Description

A car automatic locking and unlocking device

technical field

The invention relates to the field of automobile door locks, in particular to an automatic locking and unlocking device for automobiles.

Background technique

The central control door lock of the car is to make the use of the car convenient and safe, and implement centralized control of the locking and opening of each door. The door lock is an important safety component, mainly composed of two parts, one part is fixed on the door, The other part is fixed to the body and prevents the doors from opening outward through the latch, and releases them by a simple lever movement or pressing a button. The door lock must work reliably and will not disengage itself under a certain impact force. . At present, most of the cars on the market are dominated by central control door locks. The central control door lock has three main functions, namely central control, speed control and individual control. The speed control is that when the driving speed reaches a certain level, each door can automatically Locking to prevent the occupant from misoperating the door handle and causing the door to open. However, in a congested urban area, it is difficult for the car to reach its set speed, and the door cannot be self-locking to ensure the safety of the occupants. Its manufacturing cost is high and practical. It is of little significance. In order to solve the above-mentioned problems, the present invention designs an automatic locking and unlocking device for automobiles.

SUMMARY OF THE INVENTION

The purpose of the present invention is to solve the problem that the speed of the existing central control door lock is controlled in a congested urban area, and it is difficult for the car to reach its set speed.

Detailed ways

1-4, the present invention provides a technical solution: including a left front door lock 1, a right front door lock 2, a left rear door lock 3 and a right rear door lock 4, the left front door lock 1, the right front door lock 2, the left rear door The internal structure of the lock 3 and the right rear door lock 4 is the same, and they are both composed of a cover plate 7, a claw support 6 and a base plate 5. The claw support 6 is mainly composed of a lock block spring 9, a lock block 10, a buffer block 12, and a lock block. The muffler block 13 , the vibration damping block 14 , the card spring slot 15 and the slider 17 are composed. The inside of the base plate 5 is mainly composed of a linkage arm 20 , a release arm 21 , a safety arm 19 and a lever 22 . Connected with an outward opening push rod 8, a door lock control switch 23 and a door lock control relay 27 are provided around the left front door lock 1, the right front door lock 2, the left rear door lock 3 and the right rear door lock 4. The cover plate 7. The claw support 6 and the base plate 5 are fixed to each other by pins and screws, wherein the cover plate 7 and the claw support 6 constitute the locking mechanism of the lock body to realize the locking function, and the base plate realizes the inner and outer opening functions and The inner and outer lock or unlock function, the left front door lock 1 is connected with the door lock front right 2, the left rear door lock 3 and the right rear door lock 4 respectively through the electromagnetic door lock actuator 24 and the electromagnet mechanism 25, wherein the electromagnetic The door lock actuator 24 and the electromagnet mechanism 25 are electrically connected. The right front door lock 2, the left rear door lock 3 and the right rear door lock 4 are connected to each other through a linkage mechanism 26. The driver can lock the left front door 1 at the same time. Each door is locked and unlocked, which is convenient for overall control. The left front door lock 1, right front door lock 2, left rear door lock 3 and right rear door lock 4 are electrically connected to their corresponding door lock control switches 23. Each door The lock can be turned on and off independently through the door lock control switch 23, which is convenient for independent control. The switch locks between the two do not affect each other. When the seat belt 18 is fastened, the bayonet sensor 28 sends a signal to the door lock control relay 27, at this time, it controls the left front door lock 1 or the right front door lock 2 to lock; After the 18 is unlocked, the detent sensor 28 sends a signal to the door lock control relay 27. At this time, it controls the left front door lock 1 or the right front door lock 2 to unlock. Because the seat belt 18 is necessary during the driving of the car, so , the main and co-pilots are more convenient to realize automatic locking and unlocking through the seat belt 18, the left rear door lock 3 and the right rear door lock 4 are connected through the door lock control relay 27 and the weight sensor 11 in the corresponding rear seat 16 is connected , the switch lock between the two does not affect each other. When the rear passenger gets into the car, the passenger sits on the rear seat 16, and after the pressure is sensed by the weight sensor 11 in the rear seat 16, the door lock control relay 27 is sent to the door lock control relay 27. When a signal is sent, the left rear door lock 3 or the right rear door lock 4 is locked; when the rear passenger gets off the vehicle, it is necessary to manually unlock and get off the vehicle through the door lock control switch 23 .

The working principle of the present invention is:

The left front door lock 1 , the right front door lock 2 , the left rear door lock 3 and the right rear door lock 4 respectively correspond to the four doors of the car. Since the main and passenger seats must be fastened with seat belts during driving, when the seat belt 18 is fastened, the bayonet sensor 28 sends a signal to the door lock control relay 27 to control the left front door lock 1 or the right front door lock 2 at this time. Automatic locking; when the seat belt 18 is unfastened, the bayonet sensor 28 sends a signal to the door lock control relay 27, which controls the left front door lock 1 or the right front door lock 2 to automatically unlock. Since the rear occupants do not require the wearing of the seat belts 18 , in order to prevent the rear occupants from forgetting to lock the doors after getting in the vehicle, when the rear occupants get into the vehicle, the occupants sit on the rear seats 16 and pass through the rear seats 16 . After the weight sensor 11 senses the pressure, it sends a signal to the door lock control relay 27. At this time, the left rear door lock 3 or the right rear door lock 4 is locked; when the rear passenger gets off the car, it is necessary to manually pass the door lock control switch 23. Unlock and get off.
