Technical Field
[0001] The utility model relates to the technical field of automobile lamps, in particular to a damping device for an automobile front combination lamp. Background Art
[0002] The module bracket of an automobile front combination lamp is an indispensable part of an automobile lighting system. It fixes, supports and adjusts a light source module to ensure that the automobile front combination lamp can work stably and reliably, providing a clear and bright lighting effect for a driver. Usually, after the module bracket is fixedly connected to the light source module, the module bracket is fixed in a lamp housing by means of some connection structures.
[0003] The existing fixing and supporting devices generally adopt the following structure to achieve: as Figure 1 shown, a base 18 is arranged in a limiting groove of a lamp housing. A screw part of a ball head screw 19 is inserted into the base 18. A ball socket 20 is arranged on one side of the module bracket. A ball head part of the ball head screw 19 is connected to the ball socket 20 of the module bracket. Then, the module bracket is fixed by a connecting piece such as a bolt 21, that is, the fixing and supporting of the module bracket is realized through the ball head screw 19, and the connection between the lamp housing and the module bracket is realized. However, with this connection method using the ball head screw 19, although the flexible design of the ball head part of the ball head screw 19 can effectively prevent the transmission torque from being too large during the vibration process, it can only play the role of fixing and supporting the module bracket and cannot produce a damping effect. Under the influence of the vibration during the vehicle driving process, the ball head screw 19 may break, resulting in the loosening or displacement of the module bracket, further affecting the lighting effect and the service life of the module bracket, and even causing the performance of the lamp to decline or be damaged. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a damping device for an automobile front combination lamp to solve the problems existing in the above-mentioned prior art, which can absorb or offset the vibration brought during the vehicle driving process while realizing the fixing and supporting of the module bracket, play a damping role, and ensure the safety and reliability of the lamp.
[0005] To achieve the above purpose, the utility model provides the following scheme:

Detailed implementation manners
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0025] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.
[0026] The present utility model provides a vibration damping device for an automotive front combination lamp. As Figures 2 - 6 shown, it includes a spring-like member 1, which is used to fixedly support a module bracket 2. The spring-like member 1 is overall in an S shape. The spring-like member 1 includes a body 3 and two arc-shaped wings 4. The body 3 is cylindrical, and the two arc-shaped wings 4 are centrosymmetric in a direction perpendicular to the axis of the body 3. A convex shaft 7 is provided on one side of the module bracket 2. A first groove 8 in the shape of a column is provided on the side of the body 3 close to the module bracket 2. The convex shaft 7 can be inserted into the first groove 8 to achieve the connection between the module bracket 2 and the spring-like member 1. A second groove 9 is provided on the side wall at the opening of the first groove 8, and the second groove 9 communicates with the outer side wall of the body 3. A T-shaped projection 10 is provided on the outer side wall of the convex shaft 7. The T-shaped projection 10 includes a web 11 and a wing plate 12 that are connected to each other. The web 11 is snapped into the second groove 9 to further ensure the connection between the module bracket 2 and the spring-like member 1. After the web 11 is snapped into the second groove 9, the wing plate 12 is located outside the side wall of the body 3, limiting the rotation of the convex shaft 7 of the module bracket 2 in the axial direction, enabling the convex shaft 7 of the module bracket 2 to achieve self-locking, and further ensuring the stability of the connection between the module bracket 2 and the spring-like member 1. An installation hole 13 is provided on the side of the body 3 close to the headlamp housing 5, and the installation hole 13 communicates with the first groove 8. A convex shaft groove 14 is provided at the center of the convex shaft 7. A screw 15 can pass through the installation hole 13 and the convex shaft groove 14 to further ensure the firm connection between the spring-like member 1 and the module bracket 2. The arc-shaped wing 4 includes an arc-shaped root 16 and an arc-shaped wing tip 17 that are connected. The arc-shaped root 16 is connected to the side wall of the body 3, and the arc-shaped wing tip 17 can be snapped into the limiting groove 6 of the headlamp housing 5 to achieve the fixed connection of the module bracket 2 to the headlamp housing 5 via the spring-like member 1.
[0027] The damping device for the front combination lamp of an automobile provided by the utility model, in the specific application process, inserts the T-shaped protrusion 10 of the module bracket 2 into the second groove 9. At the same time, the convex shaft 7 of the module bracket 2 is inserted into the first groove 8 of the spring-like member 1. Then, the screw 15 is sequentially inserted into the mounting hole 13 of the spring-like member 1 and the convex shaft groove 14 of the module bracket 2, so that the spring-like member 1 fixedly supports the module bracket 2, realizing the fixed connection of the spring-like member 1 and the module bracket 2 into one body. Furthermore, the arc-shaped wing part 4 of the spring-like member 1 is clamped into the limiting groove 6 of the lamp housing 5, and the arc-shaped wing tip part 17 abuts against the inner side wall of the limiting groove 6. Under the vibration influence during vehicle driving, vibrations will also be generated inside the front combination lamp of the automobile. The arc-shaped wing part 4 in the utility model will vibrate together like a spring. The greater the vibration amplitude generated inside the front combination lamp of the automobile, the greater the deformation of the arc-shaped wing part 4, and the more vibrations are absorbed, enabling the spring-like member 1 to absorb and counteract the vibrations generated inside the front combination lamp of the automobile, playing a role in damping. Compared with the prior art in which the ball head screw can only play a role in fixedly supporting the module bracket 2, the utility model realizes the function of damping while fixedly supporting the module bracket 2, ensuring the safety and reliability of use of the lamp.
[0028] In this embodiment, the width of the arc root 16 in the axial direction of the body 3 is smaller than the width of the arc wing tip 17 in the axial direction of the body 3, so that the contact area between the arc wing tip 17 and the limiting groove 6 of the lamp housing 5 is larger, and the damping effect is better.
[0029] The utility model uses specific examples to elaborate on the principle and implementation manner of the utility model. The description of the above embodiments is only used to help understand the method and its core idea of the utility model; at the same time, for those of ordinary skill in the art, according to the idea of the utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the utility model.
