What is the trigger of Chang an Yuexiang central lock

The central lock structure and trigger mode are as follows:

At present, there are many types of central locks used in automobiles, but their basic components mainly include door lock switches, door lock actuators and door lock controllers.

Door lock switch: most of the central control negative switch is composed of a main switch and a sub-switch, the main switch is installed on the door next to the driver, and the driver can lock or open all the doors of the whole car by controlling the main switch; The sub-switch is mounted on each other door and can be controlled separately.

Door lock actuator: The central lock actuator is used to execute the driver's instructions to lock or open the door lock. There are three driving modes of door lock actuator: electromagnetic type, DC motor type and permanent magnet motor type.

Its structure is to lock or open the door by changing the polarity and changing the direction of its movement.

Trigger mode: 1) Electromagnetic: It is equipped with 2 coils, which are used to open and lock the door lock, and the door lock centralized operation button is usually in the middle position.

When the latching coil is given a forward current, the armature drive rod moves to the left, and the door is locked; When the reverse current is applied to the door opening coil, the armature drives the connecting rod to move to the right, and the door is removed from opening.

2) DC motor type: It is rotated by the DC motor and transmitted to the door lock through the transmission device (the transmission device has screw drive, rack drive and spur gear drive), so that the door lock lock can be opened or locked. Since the DC motor can rotate in both directions, the door lock can be locked or opened through the forward and reverse rotation of the motor.

This actuator consumes less power than an electromagnetic actuator.

3) Permanent magnet motor type: Permanent magnet motor mostly refers to permanent magnet step motor. Its function is basically the same as the previous two, but the structure is quite different.

The rotor is equipped with spur teeth, and the radial gap between the spur teeth and the magnetic pole of the stator is small and the magnetic flux is large. The stator is equipped with multiple electrodes that are axially evenly distributed, and each solenoid coil is arranged radially. When the current passes through the coil of a certain phase, the core of the coil produces suction to suck the convex teeth on the rotor to align with the magnetic pole of the stator coil, and the rotor will rotate to the minimum magnetic flux, that is, the step position.

To make the rotor continue to rotate at a step angle, a pulse of current is fed into the stator coil of the next phase according to the desired direction of rotation, and the rotor can be rotated. When the rotor rotates, the door lock is locked or opened by connecting.

This function can be restored through the settings, it is recommended that you go to the shop and ask the maintenance staff to help you set it up, I hope mine will help you.

A low battery on the key fob will cause the key light to flash, but the door will not lock. Low power and low voltage will lead to unstable circuit performance and shorten the wireless communication distance. In this case, you can lock the car close to the body.

When necessary, simply replace the battery.

There are two types of radio frequency forms of remote control key: short-range infrared remote sensing and short-range wireless radio frequency. Regardless of the form of these two, its transmitting and receiving circuits are prone to failure. This is because they are determined by three factors: circuit design, component level, and usage conditions.

Precautions for car remote locks.

Using remote control to start the vehicle, it is generally within 50 meters, beyond the scope of application, the vehicle's anti-theft, remote control, window control, etc. will not work.

After the vehicle is started remotely, the door is locked for safety reasons, and the windows are naturally all raised, and the air in the car is not circulated, so the owner needs to open the door for a while before entering the car to let the turbid heating clear.

This is a common problem of Yuexiang car, because the door sealing waterproof is very rough, so the central lock will rust, resulting in sometimes the key failure or one-time can not be opened need to press a few more times, it is recommended that if there is no insurance out of the old area 4S shop technology to replace the central lock assembly, if the city with less rain can be used for more than half a year, it is very expensive to replace it after the insurance, my moon has been close to four years, and the problem of the lock has not been solved.

I'm dizzy, your situation is the same as mine, I also bought Yuexiang in 09, white noble, the co-pilot's door central lock is not on, press the central lock car, the co-pilot and the lock is not to jump over, the lock is not always locked to find a way to lock it, and then every time I get off the car, I manually move the lock lock and lock the car, so I have been manually locking the lock for a month, one day after a month, press the lock in the central control and jump over, tested a few times, are normal, this problem is solved, you can try.

Lao Tzu's 6-year-old car, the 2013 model, has changed nearly 20 locks together.

I don't know if your car has been a few years old, is the remote control tram out of power.

As follows:

5. Emergency call, lighting, grinding and shouting rear sunshade switch, sunroof switch, etc., as shown in the figure below

GearsI hang it in the P position and the key is energized in the ON position and close four doors. Press the lock button; See the hazard indicator in the instrument flashing 2 times, automatic transmission.

The automatic car lock function is set to complete, and the manual transmission is completed.

The model automatically locks and sets the opening method, presses the ignition switch to the ON position, presses the electric door lock switch to the lock and holds it for 5 seconds within 20 seconds, and the switching operation is successful.

Chang'an Yuexiang maintenance

The hazard indicator flashes twice to indicate that the stove is opened, and the hazard indicator flashes once to indicate that it is deactivated, and the automatic lock function is realized.

The purpose is to prevent theft, and the car can be locked quickly after driving to prevent traffic jams or being pulled when waiting for traffic lights, that is, to complete the automatic car lock setting. Auto-lock is a more practical feature in the process of driving a car.

When the speed of the car reaches the set speed, the driving computer will automatically lock according to the speed of the car, which plays a certain role in safety precautions. It is important to protect the children in the car from wrenching the door of the car while the car is moving. Open it.
