Description

Sealing assembly, automobile lamp and automobile Technical Field The utility model relates to the technical field of sealing, in particular to a sealing assembly, an automobile lamp and an automobile. Background The junction between the lamp shell and the radiator of the automobile lamp needs to be sealed by using a sealing ring so as to achieve the waterproof and sealing performances and avoid the damage of electric elements in the automobile lamp. However, in the prior art, the assembly interface of the sealing ring of the car lamp, the lamp shell and the radiator has the defects that in the first aspect, the ‌ deformation matching degree of the sealing ring is insufficient, the traditional O-shaped sealing ring is easy to deform unevenly after being pressed, so that partial sealing pressure is attenuated ‌, in the second aspect, the risk of concentration of ‌ stress is large, micro crack expansion is easy to occur on a single sealing contact surface under a temperature change working condition, the sealing failure is ‌ accelerated, and in the third aspect, the assembly tolerance and the material creep amount ‌ of the lamp shell and the radiator cannot be self-adapted. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model proposes a sealing assembly, a vehicle lamp and a vehicle. The utility model solves the technical problems as follows: In a first aspect, a seal assembly is provided, comprising: the first connecting structure comprises a supporting part and a sealing part, wherein the supporting part and the sealing part are connected with each other; The second connecting structure comprises a connecting main body and a connecting step, wherein the connecting step is connected with the end face, facing the first direction, in the connecting main body, of the connecting main body, the connecting step is arranged on one side, far away from the sealing part, of the connecting main body, and extends along the first direction, the end face, facing the first direction, of the connecting step is a connecting surface, the connecting surface is connected with the supporting part, the side wall surface, facing the sealing part, of the connecting step is a main sealing surface, an annular installation space is formed between the main sealing surface and the sealing part, an auxiliary sealing surface is further arranged, and extends from the main sealing surface to the connecting surface in an inclined mode and forms a compensation groove together with the supporting part, and the compensation groove is communicated with the installation space; And the sealing ring is arranged in the installation space and is respectively abutted against the main sealing surface and the sealing part. The utility model has the advantages that the sealing ring deforms after being pressed, and the obliquely arranged auxiliary sealing surface can guide the sealing ring to extend into the compensation groove along the radial direction, so that the contact pressure distribution uniformity of the sealing ring is improved, and the sealing effect is ensured.
