Cause analysis and solution for faults in flip-board car door opening

As a common parking facility in modern courtyards, the stability and reliability are of great importance. However, occasional switch failures can cause inconvenience to the owner. The editor of Kunming Haiton Car Door New Media Centre has summarized its 33-year experience in producing, installing and repairing flip-flop warehouses, including in-depth research and solutions for common causes of flip-flop warehouse failures.

First, the cause of the failure may be due to a power problem. Checking whether the power supply is connected normally and whether the insurance wire is melted is the first step to troubleshooting this type of fault. Especially when some families have deposits, they usually add one to two backup power supplies to the power station in the villa warehouse. If the power supply is unstable or the voltage is insufficient, it may cause the power station to not work normally, which will affect the opening of the warehouse. Therefore, when checking the power supply, be sure to check whether the plug on the power supply is plugged in. If the power supply is enabled, check whether the power supply is sufficient. Solutions to solve power failures include ensuring the power is stable and regularly changing aging wires and security wires. In addition, Kunming Haiton Car Door has a solution to power failure, that is, add a power reserve to the installed car door. Even if the power is occasionally shut down, the power reserve can still be used normally by enabling the power reserve mode.

Secondly, wear or damage to door parts can also lead to opening failures. For example, problems such as door plate deformation, rail deformation, wheel wear or steel wire cracking, severe deviation of door movement may all hinder the smooth opening of the vehicle warehouse. For this type of failure, the solution is usually to replace damaged parts, or to adjust and replace the deformed parts. At the same time, intention to maintain and maintain regularly, such as applying lubricant on the chain page, cleaning up the ducts, etc., can also help reduce the wear of door parts.

Sensor failure is also one of the common causes of flip-board parking door failure. Sensors include protective mounts, red outer wire protection, gravity sensing, torsion spring force reduction, inconsistent steel wire length, etc. These protection devices and power devices are responsible for detecting the position of the door and whether they encounter obstacles during operation. If a fault occurs, it may cause the electric machine to encounter obstacles and rebound function to take effect, which will cause the vehicle warehouse door to not be opened or closed normally, which is a common problem in people\’s daily life that cannot be closed or closed. To solve this type of fault, it is necessary to check whether the connection line of the sensor is intact, whether the installation equipment of the protection device is stable, whether there is barrier covering on the surface, and whether the sensor itself is damaged, such as whether the steel wire rope is loose, whether the steel wire plate and torsion spring are shaking, etc. If necessary, a new sensor can be replaced to restore the function, or the relevant configuration can be removed directly, its function can be disabled, or the electric mode of the vehicle door can be restored. For example, if the red outer line equipment is accidentally hit by an error position or the pet pee urinates to obstruct the signal source, it may cause the switch to be disabled, and normality can be restored by disabling the red outer line.

The above is a personal experience of the Kunming Haiton Car Park New Media Editor based on previous work meetings and peer exchanges, which can solve 97% of the related problems of users during use. When encountering special cases in the work in the future, the editor will continue to summarize and continue to share. To this end, the editor revised the \”Cause Analysis and Solutions for Flip-off Cartridge Door Errors\” and wrote a more professional industry technical paper for reference.

I. Introduction

As people\’s living standards improve, the number of domestic and foreign private cars has been increasing continuously, and the development of economic development in China\’s villages has promoted the construction of self-built houses.With the rapid development, urban villa decoration has become increasingly in line with the traditional Chinese culture and is especially an important venue for parking of vehicles. Its supporting facilities are also increasingly used in the use of flip-top warehouse doors. The flip-board car door has received many youths from many courtyards and commercial venues for its small space occupied, practical beauty, and unique Oriental aesthetics. Especially young people regard the car library as a \”clear practice place\”, some people do yoga, some people practice fighting, and some people use it as a fitness venue. The underground car library in the small area has also become a red check-in and photo place on the Internet. However, during the actual use of the flip-flop door, the flip-flop door occasionally has a turnover failure, which brings inconvenience to the owner. For example, there is a sign that prohibits parking in front of the flip-flop door, or someone takes short dramas and photos in front of the luxury car to set up a friend\’s circle of friends. These failures not only affect the normal use of the lookout door, but may also have certain safety hazards. Therefore, it is important to have an in-depth analysis of the causes of the fault of the flip-board car door opening and propose effective solutions.

2. Working principle of flip-board car door

The flip-board car door is mainly composed of doors, motors, tracks, rollers, steel wire ropes, sensors and other components. Its working principle is to drive the steel wire rope through the motor, move the door up and down on the track, realizing the opening and closing of the vehicle warehouse door. During door operation, the sensor will monitor the location and operation status of the door. When a barrier or abnormal situation is detected, a signal will be issued in time to stop the motor from operating to ensure safety.

3. Turn-off faults and solutions caused by power supply problems

(I) Specific manifestations of power supply problems

Power connection abnormality:In some courtyards, the power plug of the flip-board car door motor may be loose or detached due to decoration, moving the appliance, etc., which makes the motor unable to obtain power supply and the car door cannot open or close normally.

Socket caret seal melts: When there are loading, short circuits, etc. in the circuit, the protective wire will melt and cut the circuit to protect the appliance equipment. If the circuit of the flip-flop car door fails, resulting in too high current, and the protective wire will melt, making the car door unable to work.

Improperty or insufficient power supply:Some courtyards, especially some villas, may add to the warehouse door and motorsAdd one to two backup power supplies. However, if the power supply is not stable, such as the voltage waveform is larger, or the voltage is insufficient, which is lower than the specified working voltage of the motor, the motor may not work properly, causing difficulty in starting or powerless operation, which will affect the opening of the vehicle warehouse.

(II) Methods for checking power problems

Check the power connection: First, carefully check whether the plug on the motor is plugged in and whether the connection between the plug and the socket is firm. If the plug is found to be loose, reinsert the plug. At the same time, check whether the power cable has broken or broken conditions, and if necessary, change the power cable in time.

Check the insurance seal: Check whether the insurance seal in the insurance seal box is melted. If the insulator is melted, the cause of the melting should be identified first, and after troubleshooting the circuit fault, then the insulator of the same specifications should be replaced. When replacing insurance, be careful to choose suitable insurance seals and avoid using insurance seals with excessive or too small current, so as not to affect the normal operation of the circuit or fail to protect.

Check power stability and voltage: Use a voltage meter to measure the voltage of the power supply and check whether the voltage is within the range of the motor\’s specified working voltage. If the voltage is not stable or the voltage is insufficient, consider using a stable pressure device to stabilize the voltage, or check Whether the power supply is sufficient. For the warehouse that enables the power supply, check the power supply regularly to ensure that the power supply energy is working normally when there is a problem with the main power supply.

(III) Solutions to power problems

Ensure the stability of the power supply: In order to ensure the normal operation of the flip-board car door, the stability of the power supply should be ensured. The following measures can be taken:

Installing the pressure:For areas where the voltage is unstable, it is recommended to install a pressure to ensure that the motor operates under a specified voltage. The pressure can automatically adjust the pressure.The voltage keeps the voltage within a stable range, thereby improving the working efficiency and service life of the motor.

Regularly check the power line: Regularly check the power line to see if there are any aging, broken or other conditions. For aging wires, it should be replaced in time to avoid safety hazards such as short circuits and power leakage caused by wire aging.

Rational allocation of power loads for use: In household electricity, the power loads should be allocated reasonably to avoid multiple high-power appliances being used simultaneously, resulting in circuit overload. For flip-flop truck door motors, a power circuit should be set up separately to ensure their normal operation.

Replace aging wires and insurance wires: If the wires are found to be aging or insurance wires melted, the replacement should be done in time. When changing the wire, choose a wire that meets the national standards to ensure that the cross-sectional energy of the wire meets the operating current requirements of the motor. When replacing insurance stocks, choose insurance stocks with the same specifications as the original insurance stock and avoid using inferior insurance stocks.

Add to add power reserve: In order to improve the convenience of the use of the flip-flop car door under power shutdown, Kunming Haiton Car Door proposed a solution to the power failure, that is, to add power to the installed car door. The power storage power can be used in battery and other methods. When the main power supply is powered off, the power storage power storage power can automatically switch to provide power to the motor so that the warehouse can still use the power and remote control switch modes normally. When choosing a power supply, the capacity of the power supply should be reasonably selected based on the usage frequency and working time of the warehouse to ensure that the power supply energy meets the usage needs of the warehouse.

IV. Opening faults and solutions caused by wear or damage to door parts

(I) Specific manifestations of wear or damage to door parts

Door board deformation:The door panels of the flip-board warehouse may be affected during long-term use.The impact of external force collision and temperature changes leads to deformation of the door panel. The deformation of the door panel will cause uneven gaps between the door and the track during operation, increasing the friction between the door and the track, thereby affecting the normal operation of the door.

Card is a guiding device for door operation. If the track is hit by external forces and is not installed firmly, it may cause the track to deform. The deformation of the track will cause the door to deviate from the track during operation, causing phenomena such as jamming and jamming, which will even cause the door to fall off in severe cases.

Ring wheel is a connecting component between the door and the track. During the door operation, the wheel will constantly rub against the track. If the quality of the roller is not good or the service is too long, the roller will wear. Rolling and grinding will cause noise to occur during operation, and at the same time it will affect the running stability of the door.

Steel wire cracks: Steel wire rope is an important component connecting the motor and the door. During the door operation, the wire rope bears the weight and tension of the door. ifIf the steel wire rope is of poor quality or is used for too long, the steel wire rope will crack. The steel wire cracking will cause the door to lose balance and cannot operate normally, and may even cause the door to fall and cause safety accidents.

Severe deviation of door movement refers to the door deviating from the center of the track during the operation and tilting to one side. Serious movement of doors will increase the friction between doors and the track, affecting the normal operation of doors, and at the same time, it will also cause damage to doors and tracks.

(II) Inspection method for wear or damaged door parts

Check the door panel:Clean carefully observe whether the door panel has deformation, cracks, etc. You can use a horizontal meter to measure the flatness of the door and check whether the door is horizontal. If the door plate is found to be deformed, repair or replacement should be carried out in time.

Check the track: Check the track for deformation, wear, etc. You can use a straight ruler to measure the straightness of the track and check whether the track is straight. If the track is deformed, adjustment or replacement should be made in time.

Check the roller: Check the roller for any wear or looseness. You can turn the roller with your hand to see if it is flexible. If the roller is found to be severely worn, the roller should be replaced in time.

Check the steel wire: Check whether the steel wire rope is broken or worn. You can touch the steel wire rope with your hands to check whether the surface of the wire rope is smooth. If you find that the steel wire rope is broken or worn seriously, you should change the steel wire rope in time.

Check the door operation situation:In the door operation process, observe whether the door is stable and has symptoms such as jamming or stuck. If it isThe door movement is now severely deviating, and the door position should be adjusted in time.

(III) Solutions for the wear or damage of door parts

Replace damaged parts:Replace damaged parts usually need to be replaced for problems such as door deformation, rail deformation, wheel wear, steel wire cracking, etc. When changing parts, select parts with the same specifications as the original parts to ensure the quality and performance of the parts.

Adjust and repair the deformed parts: The light deformation of the door panels and tracks can be adjusted and repaired. For example, for light slight deformation of the door panel, you can use a calibration tool to correct it; for light slight deformation of the track, you can use a track adjustment tool to adjust it. When adjusting and revising deformation parts, be careful to maintain the flatness and straightness of the door and track.

RegularlyMaintenance and maintenance: In order to reduce the wear of door parts and extend the life of doors, regular maintenance and maintenance of flip-board tanks are required.

Specific measures include:

Put the grease oil on the chain page:Put the grease oil on the chain page regularly can reduce the friction between the chain pages, reduce noise, and prevent the chain page from growing.

Cleaning the trajectory: Regularly cleaning the mists in the duct, such as dust, leaves, stones, etc., can keep the duct clean, reduce the friction between the door and the duct, and ensure the normal operation of the door.

Check the connecting parts of the door: Check the connecting parts of the door regularly, such as screws, nuts, etc. to ensure the firmness of the connecting parts. If the connecting parts are found to be loose, they should be tightened in time.

V. Turn-off faults and solutions caused by sensor failures

(I) Specific manifestations of sensor failures

Super protection bracket failure: The anti-sticking bracket is an important safety device for the flip-flop car door. Its function is to prevent the door from falling during the door operation. If the anti-sticking bracket fails, such as loose or damaged bracket, it may cause the door to fall during the operation, causing safety accidents.

Red external line protection fault:The red outer line protection device is a non-contact security protection device. The principle is to detect whether there are any obstacles during the door operation by transmitting and receiving the red outer line. If the red outer wire protection device fails, such as the red outer wire launcher or receiving tube being damaged, the red outer wire being blocked, etc., it may cause the electric machine to encounter obstacles and rebound function to take effect, thereby preventing the vehicle door from closing normally, and there may be problems such that the door cannot be closed or cannot be closed.

Gravity sensing failure: Gravity sensing device determines whether the door is operating normally by detecting the weight change of the door. If the gravity sensor device fails, such as sensor failure, parameter setting errors, etc., it may cause the motor to misjudgment the operating status of the door, thereby causing abnormal operation of the warehouse.

Torsion spring is an important power device for flip-board car doors. Its function is to balance the weight of the door and reduce the load on the motor. If the strength of the torsion spring is reduced, such as aging and cracking of the torsion spring, it may cause problems such as jamming and abnormality during the operation of the door, and it will also affect the normal opening and closing of the door.

Inconsistent length of steel wire rope: Inconsistent length of steel wire rope will cause uneven force during operation, causing problems such as deviation and locking of the door. At the same time, inconsistent length of steel wire rope will also affect the balance of the door, increase the load of the motor, and shorten the life of the motor.

(II) Methods for checking sensor failures

Check the anti-sandrack bracket: Check whether the anti-sticking bracket is firmly installed and whether the bracket is damaged or deformed. You can shake the anti-sticking bracket with your hands to check whether the bracket is loose or damaged. If the anti-sticking bracket is loose or damaged, repair or replacement should be carried out in time.

Check the Red External Protection Device:Check whether the red external line emitter and receiving tube are working normally. You can use your hands to cover the red external line and observe whether the motor will encounter obstacles and rebound. If the motor does not encounter obstacles and rebounds, explain that the red external line protection device may have a fault. At the same time, check whether the transmitting and receiving lines of the red external line are intact, and whether the wires are broken or short circuited.

Check the gravity sensing device: Check whether the sensor of the gravity sensor device is working normally. You can adjust the weight of the door and observe whether the motor can correctly determine the operating status of the door. If the motor fails to correctly determine the operating status of the door, it is explained that the gravity-sensitive device may have a malfunction. At the same time, check whether the parameter settings of the gravity sensing device are correct and whether the parameter settings meet the actual situation of the door.

Check the torsion spring: Check for the torsion spring to age, crack, etc. You can touch the torsion spring with your hands to check whether the elasticity of the torsion spring is normal. If the torsion spring is found to have aging or cracked, the torsion spring should be replaced in time. At the same time, check whether the installation of the torsion spring is correct and whether the force of the torsion spring meets the requirements.

Check the length of the steel wire rope: Measure the length of the steel wire rope and check whether the length of the steel wire rope is consistent. If the length of the steel wire rope is found to be inconsistent, the length of the steel wire rope should be adjusted in time to keep the length of the steel wire rope consistent.

(III) Solutions for sensor failure

Check sensor connection lines: Check whether the connection line of the sensor is intact and whether there are any broken or short circuits in the circuit. If you find that there is a problem with the connection line, you should repair or replace the connection line in time.

Check whether the installation equipment of the protection device is stable, whether the installation equipment is loose, deformed, etc. If you find any problem with the installation equipment, you should repair or replace the installation equipment in time.

Cleaning the surface barriers of sensors: If there is barrier mask on the surface of sensors, the barriers should be cleaned in time to ensure protectionThe sensor can work normally. For example, for the red outer line protection device, if the red outer line is obscured by dust, leaves, etc., barriers on the surface of the red outer line emitter and receiving tube should be cleaned in time.

Replace the damaged sensor: If the sensor itself is damaged, such as loose steel wire, steel wire plate and torsion spring shaking, new sensors should be replaced in time. When changing sensors, select sensors with the same specifications as the original sensor to ensure the quality and performance of the sensor.

Extract the relevant configuration or disable its functions: In some cases, if the sensor fails to be repaired in time, or the sensor function has little impact on the normal use of the vehicle warehouse, you can directly remove the relevant configuration and disable its function to restore the vehicle warehouse\’s electric mode. For example, for the Red Outer Line Protection Device, if the Red Outer Line equipment is accidentally hit by a wrong position or the pet pees urinate to obstruct the signal source, causing the switch to be disabled, and normality can be restored by disabling the Red Outer Line. But it should be noted that when removing the relevant configuration or disabling its functions, the use of the warehouse must be ensured safely.
