Car lock block action
The main functions of the car lock block include the following aspects :
Control door switch : The car lock block is the key component to control the door switch. With the lock block, the driver can easily lock or open the door. The specific operation method includes using the key and door lock switch .
Anti-theft function : car lock block with anti-theft system, can effectively prevent illegal intrusion. When the door is locked, other doors are also locked at the same time, increasing the safety of the vehicle .
Convenience : Modern car design allows the driver to lock all the doors and luggage compartment doors with one click, and can also open one door individually. This design not only improves convenience, but also prevents children from opening the door by mistake while driving.
New features brought about by technological advancements : With the development of technology, the car lock block system has also been upgraded. For example, push-button door opening systems rely on wireless communication technologies, such as RFID or BLE, to ensure the safe opening of the door through complex encryption algorithms and multiple verification mechanisms, while improving the ease of use .
Structural composition : car door lock block is usually composed of a lock body, internal and external handle, lock core and other parts. The lock body is a control mechanism, the internal and external handle is convenient for operation, and the lock core is used for key operation .
Historical background and future trend : with the development of automobile electronic control technology, there are more and more electronic control units and electronic components on automobiles, and the traditional wiring method CAN no longer meet the needs. Therefore, the electronic controller local area network (CAN) technology has emerged at the historic moment, making the modern car design mostly uses network technology to improve the integration and reliability of the system .
The working principle of automobile lock block mainly includes the principle of mechanical door lock and the principle of central control door lock.
Principle of mechanical door lock
The core of the mechanical door lock is the lock core, and its operation depends on the insertion and rotation of the key. The lock core is equipped with a precision structure such as marbles or blades, and each key tooth shape corresponds to a specific combination of marbles or blades. When the correct key is inserted and rotated, the key tooth pushes the marble or blade to the correct position, disconnecting the lock core from the lock body, allowing the lock tongue to retract and unlock. If the key is not correct, the position of the marble or blade cannot be fully matched, the lock core cannot be rotated, and the door lock remains locked.
Central control door lock principle
The central control door lock uses electrical energy to convert mechanical energy to work. Its core components include door lock switch, door lock actuator and door lock controller. The door lock switch consists of a main switch and a separate switch. The main switch is usually located on the driver's side door, which can lock or unlock the whole car door at one time. Separate doors are located on other doors, allowing individual control of each door. The door lock actuator is directed by the door lock controller and is responsible for the locking and opening of the door lock. Common actuators include electromagnetic, DC motor and permanent magnet motor. When the door lock controller issues the unlocking or locking command, the motor is energized and begins to rotate, and the lock tongue is driven by the gear, connecting rod and other transmission devices, so as to realize the opening and closing of the door lock.
Structure and function of car door lock
Car door locks are usually composed of precision components such as lock core, latch, and latch, and are connected with the central lock system or remote key system in the car. Its core function is to ensure that the door is firmly locked to prevent accidental opening of the door. In addition, the car door lock is also equipped with a convenient control mechanism, whether it is inside or outside the car, it can easily unlock the door.
Historical background and technological development
Early car keys were metal plates that could be turned to open doors and start fires. With the development of technology, the key began to integrate the identification chip, the key and the chip need to be successfully identified to start the car. Then came the remote key, which opened or closed the door by remotely pressing a button. These technological advances have led to significant improvements in vehicle safety.
