For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] refer to Figure 2-Figure 5 , the present application provides a lamp sealing structure, including:

[0038] An exterior light distribution mirror 100, wherein a buckle body 110 is provided at the edge of the exterior light distribution mirror 100;

[0039] A lamp body 200, wherein a glue injection slot 210 is provided at a portion of the edge of the lamp body 200 corresponding to the buckle body 110;

[0040] The buckle body 110 is buckled in the glue injection slot 210 , and the gap between the buckle body 110 and the glue injection slot 210 is filled with sealant 300 .

[0041] Specifically, before the external light distribution lens 100 and the lamp body 200 are pressed and fixed, the sealant 300 is injected into the glue injection slot 210 ; after the glue injection, the buckle body 110 and the glue injection slot 210 are matched and pre-fixed and compacted.

[0042] This structure can hide the glue injection slot 210 and the buckle body 110. The lamp body 200 and the buckle matching structure on the lamp body 200 are completely invisible when viewed from the front, ensuring that the outline of the lamp body 200 has no sudden changes and has a good appearance consistency.

[0043] This embodiment is easy to operate during installation and there will be no glue overflow. Due to the optimization of the depth of the glue injection slot 210, the sealing performance can be made more stable. The buckle body 110 and the glue injection slot 210 are key elements for fixing the headlight exterior lens 100 and the lamp body 200, which can ensure the fastening between the components after the seal is injected into the glue injection slot 210, ensuring a stable connection performance. The filled sealant 300 can effectively prevent the entry of moisture, dust and other external elements.

[0044] like Figure 2 and Figure 3 In some embodiments, there are multiple groups of the buckle bodies 110 and the glue injection slots 210, which are distributed on the edges of the external light distribution lens 100 and the lamp body 200.

[0045] Specifically, the cooperation of multiple groups of buckle bodies 110 and glue injection slots 210 can ensure that the edges of the external light distribution lens 100 and the lamp body 200 are firmly connected at all places, and all edges can effectively prevent the entry of moisture, dust and other external elements.

[0046] In some embodiments, the depth of the glue injection slot 210 is 17-21 mm.

[0047] Specifically, it has been verified that after adopting a depth of 17-21 mm, the glue injection depth is large and the glue injection amount is appropriate, which can ensure a sufficient waterproof level, effectively prevent the entry of moisture, dust and other external elements, and the sealing performance is more stable. As a more preferred solution, the depth of the glue injection slot 210 is 19 mm. When a depth of 19 mm is adopted, the highest waterproof level can be achieved, and the glue injection amount can be reduced, which can maintain a low cost investment.

[0048] like Figure 5 In some embodiments, it also includes: a fastener 400, which is inserted into the glue injection slot 210 from the bottom and connected to the buckle body 110.

[0049] In this embodiment, the fastener 400 can further strengthen the tightness of the connection between the external light distribution lens 100 and the lamp body 200, avoid the problem of loosening due to long-term use of simple clip connection, and ensure that the sealing structure of the present application is firm and reliable.

[0050] like Figure 5 In some embodiments, a threaded hole 111 is defined in the buckle body 110 ; the fastener 400 includes a screw, which passes through the glue injection slot 210 and is screwed into the threaded hole 111 .

[0051] Specifically, before the exterior light distribution mirror 100 and the lamp body 200 are pressed and fixed, the sealant 300 is injected into the glue injection slot 210; after the injection, the buckle body 110 and the glue injection slot 210 are pre-fixed and compacted, and then the lamp body 200 and the exterior light distribution mirror 100 are locked by passing the screws through the glue injection slot 210 and the bayonet body, thereby improving the tightness of the connection between the exterior light distribution mirror 100 and the lamp body 200.

[0052] The present application also discloses a vehicle lamp, on which the lamp sealing structure in any of the aforementioned embodiments is provided.

[0053] The present application also discloses a vehicle, comprising the vehicle light in any of the aforementioned embodiments.

[0054] The above-mentioned transportation means may be a car, a train, a high-speed train or other transportation means that require a headlight. By adopting the above-mentioned headlight, the injection slot 210 and the buckle body 110 can be hidden, and the lamp body 200 and the buckle matching structure on the lamp body 200 cannot be seen from the front view, ensuring that the outline of the lamp body 200 has no sudden changes and has good appearance consistency.

[0055] This embodiment is easy to operate during installation and there will be no glue overflow. Due to the optimization of the depth of the glue injection slot 210, the sealing performance can be made more stable. The buckle body 110 is a key element for fixing the headlight exterior lens 100 and the lamp body 200. It can ensure the fastening between the components after the seal is injected into the glue injection slot 210, ensuring a stable connection performance. The filled sealant 300 can effectively prevent the entry of moisture, dust and other external elements.
