[0002] After the headlights are mounted on the chassis, a cover plate is installed on the top or side of the headlight to protect it and cover the chassis structure. The cover plate and the headlight are usually connected by clips. This connection method is relatively stable and reliable, but if the cover plate is dented due to a slight impact or external pressure, the headlight lens can be easily damaged.

[0003] Therefore, it is necessary to provide a vehicle headlight protection structure and vehicle to solve or at least alleviate the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this utility model is to propose a vehicle headlight protection structure and vehicle, which aims to solve the technical problem that the headlight will be damaged when the cover plate connected to the headlight is dented due to external force.

[0005] To achieve the above objectives, this utility model proposes a vehicle headlight protection structure, comprising:

[0006] Lighting fixtures, including lampshades;

[0007] A cover plate, which covers at least a portion of the lampshade, and the cover plate and the lampshade together form a buffer cavity;

[0008] A buffer frame is installed in the buffer cavity. The buffer frame includes multiple support surfaces. The cover plate is fitted to all of the multiple support surfaces. The side of the buffer frame away from the support surfaces is connected to the lampshade. A buffer groove is provided between adjacent support surfaces to provide buffer space when two adjacent support surfaces move relative to each other.

[0009] In one embodiment, the cover plate has a plurality of mounting portions on the side facing the buffer frame, and the buffer frame has a plurality of snap-fit ​​holes. The mounting portions snap into the snap-fit ​​holes, and the number of mounting portions and snap-fit ​​holes are the same and they are arranged in a one-to-one correspondence.

[0010] In one embodiment, the mounting part includes a support and a snap-fit ​​rib, the snap-fit ​​rib is mounted on the support facing the snap-fit ​​hole, and the snap-fit ​​rib has a snap-fit ​​position;

[0011] The cover plate also includes a buckle, the buckle including a limiting protrusion disposed opposite to the buckle, the limiting protrusion being used to cooperate with the snap-fit ​​position so that the buckle is snapped into the snap-fit ​​rib;

[0012] The outer surface of the buckle is provided with a snap-fit ​​protrusion, which engages with the snap-fit ​​hole to snap the buckle into the snap-fit ​​hole.

[0013] In one embodiment, the snap-fit ​​position is a limiting through hole, and the limiting protrusion extends into the limiting through hole so that the buckle snaps into the snap-fit ​​rib.

[0014] In one embodiment, the buffer frame is provided with a plurality of mounting holes, and the lampshade is provided with a plurality of threaded holes on the side facing the buffer frame. The number of mounting holes and threaded holes are the same and they are provided in a one-to-one correspondence.

[0019] This utility model also proposes a vehicle including a headlight protection structure as described in any of the above embodiments, the vehicle further including a frame, and the headlight protection structure being mounted on the frame.

[0020] According to the technical solution provided by this utility model, the vehicle lamp protection structure includes a lamp, a cover plate, and a buffer frame. The lamp includes a lampshade, and the cover plate covers at least a portion of the lampshade, forming a buffer cavity with the lampshade. The buffer frame is installed in the buffer cavity and includes multiple support surfaces. The cover plate is fitted to all support surfaces, and the side of the buffer frame away from the support surfaces is connected to the lampshade.

[0034] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0037] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0038] As a crucial component of a vehicle, headlights typically provide illumination and indication. To offer some protection for the headlights and conceal the internal structure of the chassis, a cover is usually installed on the top or side of the headlight. These covers can be designed in various shapes, serving not only a protective function but also enhancing the overall aesthetics of the vehicle. In traditional installation methods, the cover and headlight are usually connected by clips. This connection method is relatively secure and reliable, ensuring that the cover and headlight do not shift relative to each other due to bumps or vibrations during driving.

[0039] However, according to the applicant's observations and research, although the snap-fit ​​connection between the headlights and the cover plate is widely used in different vehicle models, it also has certain problems. Due to the need to meet pedestrian protection regulations, the cover plate has lower rigidity compared to structures such as bumpers. This design helps to reduce the injury suffered by pedestrians after colliding with the cover plate. However, this design also makes the cover plate prone to denting when subjected to minor impacts or external pressure. Because the snap-fit ​​connection is relatively rigid, the cover plate cannot effectively absorb and disperse impact energy when subjected to external forces. External impacts are directly transmitted to the headlight lens through the cover plate, causing damage or even breakage to the lens.

[0040] In view of this, the present invention proposes a vehicle headlight protection structure to solve the above problems.

[0041] Please see Figures 1 to 3 In one embodiment of this utility model, the vehicle lamp protection structure 100 includes a lamp, a cover plate 2, and a buffer frame 3. The lamp includes a lampshade 1, and the cover plate 2 covers at least part of the lampshade 1. The cover plate 2 and the lampshade 1 enclose a buffer cavity 4. The buffer frame 3 is installed in the buffer cavity 4 and includes multiple support surfaces 31. The cover plate 2 is fitted to the multiple support surfaces 31. The side of the buffer frame 3 away from the support surfaces 31 is connected to the lampshade 1. A buffer groove 32 is provided between adjacent support surfaces 31. The buffer groove 32 is used to provide buffer space when two adjacent support surfaces 31 move relative to each other.

[0042] The technical solution of this embodiment employs a buffer frame 3 installed in a buffer cavity 4, creating a buffer structure between the lamp and the cover plate 2. When the cover plate 2 is subjected to external force, it transmits the force to the buffer frame 3 via the support surface 31. The buffer frame 3 has a buffer groove 32. After being subjected to external force, the buffer frame 3 undergoes elastic deformation, absorbing and storing the impact energy. After the external force is removed, the buffer frame 3 gradually returns to its original shape and gradually releases the stored energy. This characteristic can reduce the impact force transmitted to the lamp, thereby protecting the lamp. Furthermore, due to the presence of the buffer groove 32, when the buffer frame 3 undergoes elastic deformation, it provides buffer space for adjacent support surfaces 31, preventing the support surfaces 31 from contacting each other and thus avoiding damage caused by mutual compression. The support surface 31 increases the contact area between the cover plate 2 and the buffer frame 3, which helps to disperse the impact energy transmitted from the cover plate 2 to the buffer frame 3, thereby improving the buffering performance of the buffer frame 3.

[0043] Furthermore, it should be noted that during vehicle assembly and use, the gap or surface difference between the cover plate 2 and the lamp cover 1 needs to be controlled. If the gap or surface difference between the two does not meet the standard, mold welding and other processes are required for the cover plate 2 or the lamp cover 1. This will result in defects in the cover plate 2 or the lamp cover 1, thereby reducing the service life of the cover plate 2 or the lamp cover 1. Moreover, the mold welding process itself is complex and costly. However, with the solution provided in this embodiment, if the gap or surface difference between the cover plate 2 and the lamp cover 1 does not meet the standard, only the buffer frame 3 needs to be adjusted. The gap or surface difference between the cover plate 2 and the lamp cover 1 can be adjusted by changing the height of the buffer frame 3, without the need for mold welding or processing of the lamp cover 1 or the cover plate 2. Therefore, this solution can avoid affecting the service life of the cover plate 2 or the lamp cover 1, and at the same time reduce the cost of controlling the gap or surface difference between the cover plate 2 and the lamp cover 1.

[0044] Please see Figure 4 and Figure 5 In one embodiment of this utility model, the cover plate 2 has multiple mounting parts 21 on the side facing the buffer frame 3, and the buffer frame 3 has multiple snap-fit ​​holes 33. The mounting parts 21 snap into the snap-fit ​​holes 33, and the number of mounting parts 21 and snap-fit ​​holes 33 are the same and they are arranged one-to-one. Through the snap-fit ​​arrangement of the mounting parts 21 and the snap-fit ​​holes 33, a detachable connection between the cover plate 2 and the buffer frame 3 can be realized. The snap-fit ​​connection is convenient and quick to install, which can improve the assembly efficiency between the cover plate 2 and the buffer frame 3. At the same time, the one-to-one snap-fit ​​of multiple mounting parts 21 and multiple snap-fit ​​holes 33 can also ensure that the connection between the cover plate 2 and the buffer frame 3 is firm.

[0045] Further, please refer to Figure 4 and Figure 5In one embodiment of this utility model, the mounting part 21 includes a support 211 and a snap-fit ​​rib 212. The snap-fit ​​rib 212 is mounted on the support 211 facing the snap-fit ​​hole 33, and the snap-fit ​​rib 212 has a snap-fit ​​position 213. The cover plate 2 also includes a buckle 22, which includes a limiting protrusion 221 disposed opposite to it. The limiting protrusion 221 is used to cooperate with the snap-fit ​​position 213 so that the buckle 22 is snapped with the snap-fit ​​rib 212. The outer surface of the buckle 22 is provided with a snap-fit ​​protrusion 222, which cooperates with the snap-fit ​​hole 33 so that the buckle 22 is snapped with the snap-fit ​​hole 33. The support 211 is used to provide support for the snap-fit ​​rib 212. During the design stage, the size of the support 211 can be adjusted to adjust the position of the snap-fit ​​rib 212 so that the snap-fit ​​rib 212 can be aligned with the snap-fit ​​hole 33. During installation, the buckle 22 is first fitted onto the snap-fit ​​rib 212, so that the limiting protrusion 221 engages with the snap-fit ​​position 213, thereby enabling the buckle 22 to engage with the snap-fit ​​rib 212. Then, the buckle 22 is inserted into the snap-fit ​​hole 33, so that the snap-fit ​​protrusion 222 engages with the snap-fit ​​hole 33, thus completing the engagement process between the mounting part 21 and the snap-fit ​​hole 33. The snap-fit ​​rib 212 can be implemented in various forms; it can be a rod with the snap-fit ​​position 213 or a plate with the snap-fit ​​position 213, and the specific form can be determined according to the actual situation. Overall, the height of the snap-fit ​​protrusion 222 is greater than the diameter of the snap-fit ​​hole 33 to prevent the buckle 22 from falling out of the snap-fit ​​hole 33. In this embodiment, the support 211 and the snap-fit ​​rib 212 are integrally set, reducing the number of parts to be prepared and installed, which is beneficial to improving the assembly efficiency of the cover plate 2 and the buffer frame 3.

[0046] Furthermore, please refer to Figure 5 In one embodiment of this utility model, the snap-fit ​​position 213 is a limiting through hole 213a, and the limiting protrusion 221 extends into the limiting through hole 213a to snap the buckle 22 into the snap-fit ​​rib 212. Compared with setting the snap-fit ​​position 213 as a limiting groove, the limiting through hole 213a allows the limiting protrusion 221 to move a larger range in the snap-fit ​​position 213, and allows the limiting protrusion 221 to extend deeper into the snap-fit ​​position 213, which is more conducive to the stability of the connection between the buckle 22 and the snap-fit ​​rib 212, and reduces the possibility that the buckle 22 can be easily pulled out.

[0047] Please see Figure 2 and Figure 3In one embodiment of this utility model, the buffer frame 3 is provided with multiple mounting holes 34, and the lamp cover 1 is provided with multiple threaded holes 11 on the side facing the buffer frame 3. The number of mounting holes 34 and threaded holes 11 are the same and they are arranged one-to-one. The vehicle lamp protection structure 100 also includes a threaded rod 5, and the mounting holes 34 and threaded holes 11 are connected by the threaded rod 5. The threaded rod 5 can be a screw or a threaded rod. The connection method of the threaded rod 5 can provide more stable support for the buffer frame 3, and at the same time, it can also provide a detachable connection between the buffer frame 3 and the lamp cover, which is convenient for the maintenance or replacement of the buffer frame 3. In this embodiment, the hole wall of the threaded hole 11 protrudes from the lamp cover 1. This setting can prevent the threaded rod 5 from intruding into the interior of the lamp cover 1 and affecting the internal structural layout of the lamp. At the same time, the protruding hole wall of the threaded hole 11 is equivalent to setting a reinforcing rib on the outside of the lamp cover 1, which can improve the overall strength of the lamp cover 1 to a certain extent.

[0048] Please see Figure 3 In one embodiment of this utility model, a buffer gap 41 is provided between the side of the buffer frame 3 facing the lampshade 1 and the lampshade 1. By providing the buffer gap 41, if the deformation amplitude or collapse range is less than the size of the buffer gap 41 when the buffer frame 3 deforms or collapses, the lampshade 1 can be prevented from directly colliding with the buffer frame 3, thereby reducing the risk of the lampshade 1 being damaged by impact.

[0049] In one embodiment of this utility model, a buffer layer is provided on the side of the cover plate 2 facing the support surface 31, and the support surface 31 is fitted with the buffer layer. The presence of the buffer layer reduces the direct friction between the cover plate 2 and the support surface 31, thereby extending the service life of the cover plate 2 and the support surface 31. At the same time, the buffer layer can play a certain role in filling and supporting, making the connection between the cover plate 2 and the support surface 31 tighter, thereby improving the stability of the connection between the entire cover plate 2 and the buffer frame 3. The materials used to make the buffer layer include rubber, modified rubber, polyurethane, and other materials with a certain degree of flexibility and good wear resistance.

[0050] In one embodiment of this utility model, the buffer frame 3 is a one-piece molded part. The one-piece molded buffer frame 3 is structurally a single unit, which, compared to a structure assembled from multiple parts, provides greater overall rigidity and stronger impact resistance under the same external force. Furthermore, the one-piece molding significantly reduces the number of components required, thereby lowering component management costs. In this embodiment, the buffer frame 3 is a polypropylene support. Polypropylene has a low specific gravity and high strength; using polypropylene as the material for the buffer frame 3 ensures its impact resistance while reducing its weight. In other embodiments, the buffer frame 3 can also be made of polyethylene, polycarbonate, etc.

[0051] This utility model also proposes a vehicle, which includes a headlight protection structure 100. The specific structure of the headlight protection structure 100 is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
