Description

Technical Field

[0001] The utility model relates to the technical field of automotive lamps, in particular to a matching structure of a glue groove-fixed decorative ring. Background Technique

[0002] As an important part of an automobile, at present, in order to reduce the air resistance coefficient of new energy vehicles, the body is becoming more and more in line with dynamics, but the space of the lamps is being compressed again and again. Many traditional screw-locking structures have been gradually replaced by structures with small required spaces such as riveting and snap-fitting for fastening parts. However, sometimes the front lamps often need to be placed close to many parts of the surrounding body due to the shape requirements. Many parts inside the lamp cannot be arranged with reliable mounting feet for fastening or small-sized snap structures. For example, if the lamp decorative ring cannot be locked tightly, problems such as vibration abnormal noise, powdering, damage to internal parts and components are likely to occur.

[0003] Therefore, it is necessary to borrow and cooperate with each other in the existing limited structural space and make reasonable use of every part of the space. For example, the screw-locking part of the decorative ring is moved into the glue groove and fixed by pressing with the light distribution mirror and glue adhesion and sealing. In order to ensure the bonding force of the glue, the glue groove of the lamp housing will be activated, but the flanging of the decorative ring blocks the bottom and side of the glue groove of the lamp housing, making it impossible for the glue to cover the glue groove of the lamp housing well, so many airtight problems such as air leakage and water leakage occur. Content of the Utility Model

[0004] The purpose of the utility model is to provide a matching structure of a glue groove-fixed decorative ring to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A matching structure of a glue groove-fixed decorative ring, including a lamp housing, and further including:

[0006] A light distribution mirror arranged inside the lamp housing, a decorative ring is arranged between the lamp housing and the light distribution mirror, and a fixing mechanism for connection is arranged among the lamp housing, the light distribution mirror and the decorative ring. The fixing mechanism includes a glue groove opened inside the lamp housing, a bearing step is arranged on the inner side of the lamp housing, a vertical plate is fixed on the top of the bearing step, a guiding and limiting rib is fixed on the inner wall of the glue groove, a positioning rib is fixed on the top of the bearing step, and glue for bonding is arranged among the lamp housing, the light distribution mirror and the light distribution mirror.

[0007] Preferably, the light distribution mirror is snap-fitted inside the lamp housing, the materials of the light distribution mirror and the decorative ring are both set as polycarbonate, and the material of the lamp housing is set as polypropylene.

[0008] Preferably, the light distribution mirror includes a mirror body arranged inside the lamp housing, and a vertical plate is fixed at the bottom of the mirror body, and the vertical plate is arranged on the top of the bearing step.

[0009] Preferably, a horizontal plate is fixed to one side of the lens body, and the horizontal plate is arranged on the top of the vertical plate.

[0010] Preferably, the decorative ring includes a ring body inserted into the inside of the lamp housing, and a plug board is fixed to the bottom of the ring body, and the plug board is inserted into the inner wall of the glue groove.

[0011] Preferably, a clamping plate is fixed to one side of the ring body, and the clamping plate is inserted between the bearing step and the vertical plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By the mutual cooperation of the fixing mechanism and the glue in the present utility model, the connection between the lamp housing, the light distribution lens and the decorative ring is more stable. In the current promotion of lamps in narrow spaces, the glue groove fixing decorative ring matching structure that borrows space from each other has small space size requirements, is stably matched, has stable performance, wide application, and at the same time, the costs of parts materials and part molds will be reduced. It avoids the decorative ring flanging from blocking the bottom and side of the glue groove of the lamp housing, so that the glue cannot well cover the glue groove of the lamp housing, resulting in many airtight problems such as air leakage and water leakage.
