Detailed Implementation

[0025] The following will refer to the appendix in the embodiments of this utility model. Figures 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example:

[0027] like Figures 1 to 6 As shown, this utility model discloses a novel car door lock bracket, including a bracket body 1, on which a plate rotating shaft 2 is provided, as shown in the figure. Figure 4 As shown, the card plate rotation shaft 2 is used for the card plate 8 to rotate and fit on it. In addition, the bracket body 1 has a card plate rotation limiting groove 3 on the upper side of the card plate rotation shaft 2. The card plate rotation limiting groove 3 is used for the card plate protrusion 81 on the card plate 8 to be movably disposed in it, and plays a role in limiting the card plate protrusion 81. When the card plate 8 rotates, the card plate protrusion 81 rotates in the card plate rotation limiting groove 3. In this utility model, a limiting block 4 is integrally formed on the side of the card plate 8 away from the card plate rotation shaft 2 on one side of the card plate rotation limiting groove 3. The limiting block 4 is used to limit the card plate protrusion 81. 1. The limiting block 4 is provided with several honeycomb holes 41. The honeycomb holes 41 extend through the side of the limiting block 4 away from the bracket body 1. The honeycomb holes 41 can effectively absorb and disperse impact energy, reduce the energy transmitted to other parts, and reduce noise. Therefore, the limiting block 4 of this structure can effectively play the role of buffering and shock absorption. In addition, this structure is easy to injection mold and eliminates the separate design of the door lock bracket and the buffer block. No additional parts are required, which simplifies the assembly process. Therefore, it plays the role of reducing costs and making it easier to control.

[0028] Further, the limiting block 4 is in a concave shape, and the notch position faces the clamping plate rotating limiting groove 3, so that the area of the integral molding between the limiting block 4 and the support body 1 can be effectively increased, thereby improving the structural strength.

[0029] Wherein, the limiting block 4 includes a notch contact surface 42 located in the clamping plate rotating limiting groove 3, and the limiting block 4 is provided with a plurality of buffer corrugations 5 on the notch contact surface 42. The buffer corrugations 5 can effectively absorb and disperse impact energy, thereby achieving the effect of shock absorption and buffering.

[0030] Further, a plurality of reinforcing ribs 6 are integrally formed between the side wall of the limiting block 4 and the support body 1, and the reinforcing ribs 6 are used to further improve the structural strength of the limiting block 4 integrally formed on the support body 1.

[0031] In the utility model, the clamping plate rotating speed slowing structure is arranged on the limiting block 4 and located on the clamping plate rotating limiting groove 3. Specifically, the clamping plate rotating speed slowing structure includes a speed reduction plate 7, and the speed reduction plate 7 is integrally formed on the limiting block 4. The speed reduction plate 7 covers one side of the clamping plate rotating limiting groove 3, and a wave-shaped contact protrusion 71 is arranged on the side of the speed reduction plate 7 facing the clamping plate rotating limiting groove 3. When the clamping plate protrusion 81 rotates and approaches the limiting block 4, the clamping plate protrusion 81 first contacts the speed reduction plate 7. The wave-shaped contact protrusion 71 on the speed reduction plate 7 will form a certain resistance to the clamping plate protrusion 81. The speed reduction plate 7 has a certain deformation capacity, so it will not cause the clamping plate protrusion 81 to not contact the limiting block 4. However, the speed reduction plate 7 will slow down the speed of the clamping plate protrusion 81 through the contact with the clamping plate protrusion 81, thereby reducing the force of the clamping plate protrusion 81 impacting on the limiting block 4. In addition, the speed reduction plate 7 can be directly injection molded by a mold, which will not hinder demolding and is easy to produce.

[0032] It should be pointed out that the terms indicated in the utility model, such as "front", "rear", "vertical", "horizontal", and the like, indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the utility model.

[0033] The above description is only the preferred embodiment of the utility model, and is not used to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
