How the car trunk lock works.
The working principle of the car trunk lock mainly involves the synergistic effect of the mechanical structure and the electronic control system.
First of all, from the mechanical structure point of view, the trunk lock machine is usually composed of a lock shell, lock core, lock tongue, spring, handle and so on. The lock shell is the shell of the whole lock machine, and the lock core is the core component, which realizes the function of locking and unlocking by pushing the lock tongue by the spring. When the latch retracts, the trunk can be opened; When the latch is extended, the trunk is locked.
Secondly, the electronic control system also plays an important role in the work of the car trunk lock. For example, the electronically controlled door lock system realizes the unlocking and locking of the trunk door lock through the control of components such as relays, ECUS (electronic control units) and door lock motors. When the main switch and the trunk door lock switch are opened, the anti-theft door lock computer receives the trunk unlock request signal, and completes the circuit of the electromagnetic coil of the trunk door lock through the function of the frequency converter and the trunk unlock timer, thus opening the trunk door lock.
In addition, inductive trunk cover technology provides a more convenient way to open. This technology uses intelligent sensing technology to automatically unlock and close the luggage compartment. When the vehicle is turned off, carry a valid car key into the designated identification zone and activate the Easy open function by kicking the sensor area under the rear bumper, so that the luggage lid will automatically unlock and open. When the foot is kicked again, the Easy close function is activated and the trunk lid closes automatically. The working principle of this kicking electric tailgate is to trigger the tailgate switch by analyzing the signal changes received by two antennas installed in different positions.
To sum up, the working principle of the car trunk lock combines the technology of the mechanical structure and the electronic control system, and realizes the locking, unlocking and induction automatic opening and closing functions of the trunk through the synergy of mechanical components such as the lock core, spring, handle and relays, ECU, door lock motor and other electronic control components.
The suitcase won't open
1. Squeeze to solve problems. Don't open the suitcase. It's stuck. Maybe there's too much stuff in the suitcase, and the lock inside is stuck. At this time, you can squeeze the suitcase hard to reduce the burden of the lock, and then press the unlock key to open the suitcase. 2. Open the suitcase directly, the suitcase can not be opened, which may be the reason for the damage of the combination lock. Then, using a screwdriver or wrench, remove the combination lock from the suitcase, open the suitcase, and then buy a matching combination lock from the store to reinstall it. 3. Unlock the password. If you forget the password, the suitcase wins. At this time, observe the structure of the internal structure under the combination lock, find the adjacent three iron plates, and then turn the roulette of the combination lock, so that the grooves on the three iron plates face left, press the lock, and open the suitcase. How to repair the expansion of the luggage rod is broken 1. The luggage rod is not flexible, can not be pulled with brute force, can be repaired with lubricating oil. Lubricating oil can play the role of lubrication. Slowly add a little grease to the wall of the bar, wait patiently for a few minutes, and then push and pull the bar of the suitcase until it is smooth. 2. Once the trunk lever is pulled open, there is no way to successfully profit. Too much force can cause jamming. You can shake the box from side to side with a pull rod to reset the spring bead on the pull rod, or open the box, look for the spring bead stuck, press back, and sand the damaged part with an emery cloth or a blade.
