[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] See also Figure 1-5 The utility model provides a technical solution: an automotive electronic door lock shrapnel, comprising a main board 1, a side wing plate 2, a rebound plate 3, an arc hook 4, a slot 5, a pressure plate 6, a protrusion 7, a slider 8, a pressure rod 9, a push rod 10, a slide groove 11, and a spring 12.
[0030] Embodiment 1: The automotive electronic door lock spring is provided with a stable rebound structure, which can make the spring more stable through the arc hook 4 when it is pressed and rebounded, specifically:
[0031] The front end of the main board 1 is set to a trapezoidal structure, including a slot 5, which is opened on the upper surface of the main board 1. The main board 1 is connected to a stable rebound structure, which can rebound through the rebound plate 3 and the arc hook 4 while being limited by the side wing plate 2. The stable rebound structure also includes a side wing plate 2, which is fixedly installed on the side surface of the main board 1. Two rebound plates 3 are installed at the front end of the main board 1, and a protrusion 7 is arranged between the two rebound plates 3, and the protrusion 7 is fixedly installed at the front end of the main board 1. The rebound plate 3 is set to an inclined structure, and an empty slot is arranged between the rebound plates 3. The lower end of the rebound plate 3 is fixedly provided with an arc hook 4. A pressing plate 6 is installed on the inner wall surface of the slot 5 on the upper surface of the main board 1. The pressing plate 6 is elastically connected to the main board 1, and the pressing plate 6 is set to an inclined structure. The lower end of the side wing plate 2 is provided with an inclined block;
[0032] The electronic door lock shrapnel of the automobile will cause the main board 1 to be subjected to forward pressure when the electronic door lock of the automobile is powered on. Figure 1As shown, when the main board 1 is pressurized, the rebound plate 3 will be squeezed, and the rebound plate 3 is connected to the front end of the trapezoidal structure of the main board 1, and an empty groove is arranged between each rebound plate 3, so that the rebound plate 3 can react quickly when the main board 1 pressurizes, and the arc hook 4 at the lower end of the rebound plate 3 is fixedly installed, so that the upper half of the rebound plate 3 moves forward, and then the protrusion 7 between the rebound plates 3 triggers the switch forward, and then the rebound plate 3 returns to its original position under the rebound force of the rebound plate 3. When the main board 1 and the rebound plate 3 move, since the lower end of the side wing plate 2 installed on the side surface of the main board 1 is provided with an inclined block, the rebound trajectory will be limited, so that the spring piece is more stable when it is pressed and rebounds.
[0033] Embodiment 2: The automotive electronic door lock spring is provided with a buffer structure, through which the spring can be more resistant to pressure when absorbing the impact of pressure, specifically:
[0034] The main board 1 is also connected with a buffer structure, which can push the slider 8 to squeeze the spring 12 for buffering when the pressure plate 6 is under pressure. The buffer structure includes a slider 8, the lower surface of which is slidably mounted on the upper surface of the pressure plate 6, one end of the pressure plate 6 is located above the slot 5, the front end of the slider 8 is fixedly connected with a pressure rod 9, the pressure rod 9 is fixedly connected with a push rod 10, and the push rod 10 is slidably connected with a slide groove 11, the slide groove 11 is fixedly mounted on the upper surface of the main board 1, the front end of the pressure rod 9 is fixedly mounted with a spring 12, and the other end of the spring 12 is mounted on the outer surface of the protrusion 7, the spring 12 is located between the slide grooves 11, and the front surface of the protrusion 7 is provided with an opening corresponding to the push rod 10;
[0035] When the main board 1 is pressed, the pressure plate 6 will be pressed downward, and then the front end of the pressure plate 6 will reach between the slots 5. Figure 5 As shown, the front end of the pressure plate 6 will push the slider 8, so that the slider 8 slides on the upper surface of the main board 1, and then the pressure rod 9 is pushed by the slider 8. The push rods 10 installed on both sides of the pressure rod 9 slide through the slide groove 11. The front end of the push rod 10 will pass through the opening set on the front surface of the protrusion 7, so that the push rod 10 and the protrusion 7 trigger the switch at the same time. At the same time, the pressure rod 9 will squeeze the spring 12 between the slide groove 11 to buffer the pressure. When rebounding, the spring 12 will push the pressure rod 9, so that the slider 8 returns to its original position, which is convenient for next use.
[0036] Working principle: When using the automotive electronic door lock shrapnel, a stable rebound structure is provided. While rebounding through the rebound plate 3, the side wing plate 2 is limited to make the rebound more stable. A buffer structure is also provided, which can push the slider 8 through the pressure plate 6 to squeeze the spring 12 for buffering, thereby increasing the overall practicality.
