Technical Field
[0001] This utility model relates to the field of automotive headlight technology, and in particular to an automotive headlight with collision buffer. Background Technology
[0002] As a key component of vehicle lighting, car headlights play a vital role in vehicle operation. However, in the event of a collision, existing car headlights often lack an effective buffer structure, leading to broken lenses and damaged lamp bodies. This not only affects the lighting function but may also generate debris that could cause secondary injuries to pedestrians or occupants.
[0003] While some headlights on the market currently incorporate simple impact mitigation measures, their effectiveness is poor, and their complex structure and high cost make them unsuitable for practical use. Therefore, there is an urgent need to design a novel, effective, and cost-efficient automotive headlight with collision mitigation capabilities. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:
[0005] A car headlight with collision buffer includes a headlight body, a buffer seat is provided at the lower front end of the headlight body, a buffer groove is provided inside the buffer seat, and an anti-collision component is provided inside the buffer groove.
[0006] The anti-collision component includes a connecting rod positioned directly below the buffer seat. Several evenly spaced fixed posts are fixedly mounted on the upper end of the connecting rod. Several movable through slots are opened inside the upper front side of the buffer seat, and these slots are connected to the buffer groove. The upper ends of several fixed posts are movably inserted into the movable through slots. A buffer roller is rotatably mounted on the outer side of each fixed post, and a rubber pad is fitted onto the outer surface of the buffer roller. At least three of the fixed posts have fixing mechanisms at their upper ends, and a buffer mechanism is provided inside the buffer groove.
[0007] As an improvement to the above technical solution, the buffer seat is located at the lower front end of the headlight body, and a fixing bolt is fitted between the buffer seat and the headlight body.
[0008] As an improvement to the above technical solution, the fixing mechanism includes several guide grooves formed on the upper surface of the buffer seat, and the guide grooves are located on both sides of the movable through groove. A fixing ring is fixedly sleeved on the upper outer surface of the fixing column, and the fixing ring is located at the upper end of the buffer seat. A fixing member is movably sleeved on the outer surface of the fixing column, and the fixing member is located at the upper end of the fixing ring. Two fixing nuts are screwed onto the top outer surface of the fixing column, and the top outer surface of the fixing column is provided with threads that are compatible with the fixing nuts. The fixing nuts are located at the upper end of the fixing member.
[0009] As an improvement to the above technical solution, guide blocks are fixedly installed on the lower sides of both ends of the fastener, the guide blocks are movably disposed inside the guide groove, and the diameter of the fixing ring is smaller than the width of the movable through groove.
[0010] As an improvement to the above technical solution, the buffer mechanism includes a movable seat disposed on the rear side of the fixed column. An arc-shaped groove is formed in the middle of the front surface of the movable seat. The fixed column is disposed inside the arc-shaped groove. Two dampers are disposed on the rear side of each movable seat.

The movable seat is a hard rubber component.
[0012] The beneficial effects of this utility model are:
[0013] 1. By setting a buffer seat on the lower front side of the headlight body, and opening a buffer groove on the inner side of the buffer seat, and setting an anti-collision component inside the buffer groove, when an external object is about to hit the headlight body, it will first contact the protruding buffer seat under the headlight body. Several buffer rollers are rotatably set in front of the buffer seat. When an external object hits the headlight body, it will first hit several buffer rollers. The buffer rollers will start to rotate upon impact, thereby buffering the impact force. At the same time, in conjunction with the buffer mechanism set behind the fixed column, the buffer rollers will also move backward while rotating upon impact, thereby further buffering and damping the impact force, thus protecting the headlight body and increasing the overall anti-collision performance of the device.
[0014] 2. A fixing mechanism is set at the top of the fixing column. The fixing mechanism facilitates the disassembly of the fixing column and the connecting rod, so that when several buffer rollers are damaged, the buffer rollers can be replaced easily, thereby increasing the convenience of replacing the buffer rollers.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0023] Please see Figure 1-6 This utility model provides a technical solution:
[0024] A car headlight with collision buffer includes a headlight body 1, a buffer seat 2 is provided at the lower front end of the headlight body 1, a buffer groove 21 is provided inside the buffer seat 2, and an anti-collision component is provided inside the buffer groove 21.
[0025] The anti-collision component includes a connecting rod 4 located directly below the buffer seat 2. Several fixed posts 41 are fixedly installed at equal intervals on the upper end of the connecting rod 4. Several movable through slots 22 are opened inside the upper front side of the buffer seat 2, and the movable through slots 22 are connected to the buffer groove 21. The upper ends of the fixed posts 41 are respectively movably inserted into the interior of the movable through slots 22. A buffer roller 3 is rotatably arranged on the outer side of the fixed posts 41. A rubber pad 31 is sleeved on the outer surface of the buffer roller 3. At least three fixed posts 41 are provided with a fixing mechanism at their upper ends. A buffer mechanism is provided on the inner side of the buffer groove 21.
[0026] In this embodiment, a buffer seat 2 is provided on the lower front side of the headlight body 1, and a buffer groove 21 is opened on the inner side of the buffer seat 2. An anti-collision component is provided inside the buffer groove 21. Under the action of the anti-collision component, when an external object is about to hit the headlight body 1, it will first contact the buffer seat 2 protruding below the headlight body 1. Several buffer rollers 3 are rotatably arranged in front of the buffer seat 2. When an external object hits the headlight body 1, it will first hit several buffer rollers 3. The buffer rollers 3 will start to rotate when they are hit, thereby buffering the impact force. At the same time, in conjunction with the buffer mechanism provided on the rear side of the fixed column 41, the buffer rollers 3 will also move to the rear side while rotating when they are hit, thereby further buffering and shock-absorbing the impact force, thus protecting the headlight body 1.
[0027] Specifically, the buffer seat 2 is located at the lower front end of the headlight body 1, and a fixing bolt 6 is fitted between the buffer seat 2 and the headlight body 1.
[0028] Specifically, the fixing mechanism includes several guide grooves 23 formed on the upper surface of the buffer seat 2, and the guide grooves 23 are located on both sides of the movable through groove 22. A fixing ring 42 is fixedly sleeved on the upper outer surface of the fixing post 41, and the fixing ring 42 is located at the upper end of the buffer seat 2. A fixing member 43 is movably sleeved on the outer surface of the fixing post 41, and the fixing member 43 is located at the upper end of the fixing ring 42. Two fixing nuts 44 are screwed onto the top outer surface of the fixing post 41, and the top outer surface of the fixing post 41 is provided with threads that are compatible with the fixing nuts 44. The fixing nuts 44 are located at the upper end of the fixing member 43. Guide blocks 45 are fixedly installed on the lower sides of both ends of the fixing member 43. The guide blocks 45 are movably disposed inside the guide groove 23. The diameter of the fixing ring 42 is smaller than the width of the movable through groove 22.
[0029] In this embodiment, a fixing mechanism is provided at the top of the fixing column 41. The fixing mechanism facilitates the disassembly of the fixing column 41 and the connecting rod 4, so that when several buffer rollers 3 are damaged, it is easy to replace the buffer rollers 3, thereby increasing the convenience of replacing the buffer rollers 3. At the same time, when a buffer roller 3 is damaged due to impact, the fixing nut 44 screwed on the top of the fixing column 41 can be removed with a tool, and then the fixing parts 43 can be removed one by one. Since the diameter of the fixing ring 42 is smaller than the width of the movable through groove 22, the connecting rod 4 and the fixing column 41 can be removed, so that the damaged buffer rollers 3 and rubber pads 31 can be replaced in time, increasing the convenience of replacement.
[0030] Specifically, the buffer mechanism includes a movable seat 52 located behind the fixed post 41. An arc-shaped groove 53 is formed in the middle of the front surface of the movable seat 52. The fixed post 41 is located inside the arc-shaped groove 53. Two dampers 5 are provided on the rear side of each movable seat 52. One end of the damper 5 is fixedly connected to the inner wall of the buffer groove 21, and the other end of the damper 5 is fixedly connected to the rear surface of the movable seat 52. A spring 51 is sleeved on the outer side of each damper 5. One end of the spring 51 is fixedly connected to the inner wall of the buffer groove 21, and the other end of the spring 51 is fixedly connected to the rear surface of the movable seat 52. The movable seat 52 is a hard rubber component.
[0031] In this embodiment, a buffer mechanism is provided inside the buffer groove 21. Under the action of the buffer mechanism, when an external object hits the buffer roller 3 and the rubber pad 31, the buffer roller 3 rotates. At the same time, the buffer roller 3 and the fixed column 41 move backward. The fixed column 41 moves inside the movable through groove 22, driving the guide block 45 to slide inside the guide groove 23. With the cooperation of the guide block 45 and the guide groove 23, the deviation of the fixed column 41 and the buffer roller 3 during movement can be avoided. During the process of the buffer roller 3 and the fixed column 41 moving backward, the fixed column 41 will squeeze the movable seat 52 to move backward, thereby squeezing the spring 51 and the damper 5, which can buffer and dampen the external impact force, thereby protecting the headlight body 1.
[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
