[0002] Automobile door locks are an important part of modern automobiles. They are not only used to protect the safety of the vehicle and the items inside the vehicle, but also used to provide convenient entry and exit functions. A door lock mechanism is provided inside the automobile door lock. A sensor inside the door lock mechanism is connected to a motor, and the motor is responsible for actually opening or closing the door lock. The sensor is used to detect the vehicle state and send a signal to the motor to trigger corresponding actions.

[0003] In some current automobiles, collision sensors are provided inside the collision safety unlocking structure. These collision sensors are designed to detect whether a vehicle has collided or encountered an accident, and unlock the door as needed to facilitate the escape of passengers. However, traditional collision sensors respond to various types of vibrations or impacts, and these vibrations or impacts are not actual collisions. Instead, when the vehicle encounters potholes, speed bumps or other uneven road surfaces during driving, the sensor will misjudge it as a collision.

[0004] Therefore, the utility model designs a collision safety unlocking mechanism for automobile door locks. Summary of the Utility Model

[0028] Embodiment

[0029] As Figures 1-6 As shown in the figure, the automobile door lock collision safety unlocking mechanism proposed by the present utility model includes an automobile door 1 and a door lock mechanism provided on the automobile. The door lock mechanism is provided with an unlocking motor, and further includes: an installation groove 111 opened inside the automobile door 1; a switch mechanism installed in the installation groove 111 to activate the door lock mechanism after a collision; and a bracket mechanism provided in the installation groove 111 to support the switch mechanism to maintain a balanced placement after a collision.

[0030] Furthermore, the switch mechanism includes a cover 2. The bottom of the cover 2 is fixedly connected to a conical cover 6. Inside the cover 2, there is a support block 3. The lower surface of the support block 3 is fixedly connected to a plurality of support rods 7. The bottom ends of the support rods 7 are fixedly connected to the inner wall of the conical cover 6. The top of the support block 3 is provided with a conical groove 4. The inner bottom wall of the conical groove 4 is provided with a rolling ball 5. The rolling ball 5 is made of carbon steel or alloy steel.

[0031] Among them, the switch mechanism further includes a guide tube 8 fixedly connected to the bottom of the conical cover 6. The bottom end of the conical cover 6 is provided with a sliding opening 15 communicating with the guide tube 8 and allowing the rolling ball 5 to pass through. The bottom of the guide tube 8 is inserted with a collision sensor 10. The collision sensor 10 is also called a collision detection sensor or a collision detection device, which is a device used to detect when an automobile collides or is impacted. These sensors are an important part of the automobile safety system and can quickly trigger safety devices when a collision event occurs to protect the occupants in the vehicle. The bottom of the collision sensor 10 is fixedly connected to the top of the center-of-gravity bottom ball 11. The automobile door 1 is provided with a controller. The input end of the controller is connected to the collision sensor 10, and the output end of the controller is connected to the motor of the door lock mechanism.

[0032] Furthermore, the bracket mechanism includes a retaining ring 12 for supporting the conical cover 6. A plurality of balls 13 are arranged on the retaining ring 12 in a circumferential array and contact the bottom of the conical cover 6. The function of the balls 13 is to make the sliding of the switch mechanism on the retaining ring 12 smoother. A plurality of connecting rods 14 are fixedly connected to the outer wall of the retaining ring 12, and one end of each connecting rod 14 away from the retaining ring 12 is fixedly connected to the inner wall of the installation groove 111. The bracket mechanism further includes a plurality of clamping claws 9 fixedly connected to the bottom of the guide tube 8 and arranged linearly. The bottom of the clamping claws 9 fixedly holds a gravity bottom ball 11, and the material of the gravity bottom ball 11 is metal steel.

[0033] In this embodiment, when the automotive door lock collision safety unlocking mechanism needs to be used, as Figure 2 shown, when the automotive door 1 is violently collided, at this time, the bracket mechanism in the installation groove 111 will be violently impacted, and at the same time, the switch mechanism on the bracket mechanism will also be violently impacted. Then, the ball 5 in the conical groove 4 is disengaged from the inner bottom wall of the conical groove 4, and then the ball 5 slides into the conical cover 6 at the bottom of the cover 2, passes through the sliding opening 15 at the bottom of the conical cover 6, and then hits the collision sensor 10 through the guide tube 8. After being collided, the collision sensor 10 will be activated, and after being activated, it will send a signal to the controller. After receiving the signal and being activated, the controller will send an instruction to the motor in the door lock mechanism, and finally, the motor can be made to open the automotive door lock, so that the automotive door lock is automatically opened; when the automotive door 1 passes through a bumpy road section, at this time, the ball 5 on the switch mechanism will only slide in the conical groove 4. At the same time, when the automotive vehicle goes uphill, at this time, the conical cover 6 slides through the plurality of balls 13 in the retaining ring 12. The cover 2 at the top of the switch mechanism is lighter, but the gravity bottom ball 11 at its bottom is heavier. When the switch mechanism is tilted, gravity will generate a reset moment, pulling it back to the upright position, so that the ball 5 will not be disengaged from the conical groove 4 to trigger the collision sensor 10.

[0034] The preferred embodiments of the above utility model are only used to help illustrate the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only the specific implementation manners. Obviously, according to the content of this specification, many modifications and changes can be made. These embodiments are selected and specifically described in this specification to better explain the principle and practical application of the utility model, so that those skilled in the relevant technical field can well understand and utilize the utility model. The utility model is only limited by the claims and their full scope and equivalents.
