Description

Technical Field

[0001] The utility model belongs to the field of vehicle lamps, and in particular relates to a thick-walled part of a vehicle lamp. Background Art

[0002] The thick-walled parts of the headlights are wall-shaped components made of special materials. They are installed inside the headlight housing to fully reflect and refract the light, thus protecting the light source and reflector of the headlights. The thick-walled parts can effectively block the light inside the headlights, avoid light scattering and light leakage, and improve the focus and brightness of the light beam.

[0003] The thick-walled parts of existing headlights are generally fixed to the brackets by multiple screws, but this fixing method is cumbersome to install, and the shape of the thick-walled parts will affect the internal space of the headlights, and even affect the optical effect of the headlights. If the number of screws used is reduced, the thick-walled parts will cause problems due to vibration. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a thick-walled part for a vehicle lamp.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model is further configured as follows: the bracket has a second connection surface arranged at an angle to the first connection surface, and the thick-walled light guide has a second installation surface arranged away from the first installation surface;

[0008] The second connecting surface is provided with a plurality of first limiting structures, the first limiting structures include positioning sleeves, the second mounting surface is provided with a second limiting structure, the second limiting structure includes a positioning seat protruding from the second mounting surface, and the positioning sleeves cooperate and abut against the positioning seat.

[0009] The utility model is further configured as follows: the first limiting structure also includes a convex column arranged parallel to the positioning sleeve, a positioning hole is arranged on the positioning seat, and the convex column passes through the positioning hole.

[0010] The utility model is further configured as follows: a first limiting protrusion in contact with the inner side wall of the bracket is provided at the bottom of the thick-walled light guide member to form a first mounting surface.

[0011] The utility model is further configured as follows: a buckle plate is provided on the outer edge of the first connecting surface, a buckle hole is provided on the buckle plate to form a first connecting portion, a pit is provided on the first mounting surface to match the buckle plate, a protrusion is provided in the pit to match the button hole to form a second connecting portion.

[0012] The utility model is further configured as follows: a recessed portion extending to the outer edge of the first connecting surface is provided on the first connecting surface to form a first limiting portion, and a plate matching the recessed portion is provided on the outer edge of the first mounting surface to form a second limiting portion.

[0013] The utility model is further configured as follows: the first opening is located at the lower part of the side wall of the bracket, the first connecting surface is located on the bottom outer surface of the bracket, and the first mounting surface is located on the bottom outer surface of the thick-walled light guide.
