[0006] A raised grid-like light distribution pattern is formed on the light emitting surface, and a step slope is left at the edge of the light distribution pattern with a width of 0.2 mm.

[0007] Preferably, the light distribution pattern includes a plurality of pattern blocks arranged in a linear array on the light emitting surface to form a grid-like light distribution pattern, and the edge of the pattern block on the outermost side is chamfered to form a step surface with a width of 0.2 mm with the light distribution pattern.

[0008] Preferably, the pattern block is in the shape of a raised arc.

[0009] Preferably, the reflecting surface is a structure that protrudes backward from the light incident surface of the thick-walled part, the thick-walled part is in the shape of an elongated strip, and a plurality of reflecting surfaces are evenly spaced and arranged along the length direction of the thick-walled part.

[0010] Preferably, the thick-walled part body is made of PC plastic.

[0011] Preferably, mounting feet are arranged on the thick-walled component body.

[0012] The present invention also claims protection for a vehicle lamp, including a thick-walled vehicle lamp part.

[0013] The present invention also claims protection for a vehicle including a vehicle lamp.

[0014] Beneficial Effects

[0015] The utility model provides a thick-walled car lamp part that is easy to demould. By leaving a step slope with a width of 0.2mm at the edge of the light distribution pattern, firstly, the laying area of ​​the light distribution pattern is corrected, the laying area is reduced, and the light distribution requirements of thick-walled parts in the market can be met. What is more rare is that without significantly changing the shape of the laying surface of the light distribution pattern and changing the style, it can also make the mold demoulding easier and batch processing easier.

[0016] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained by the structures indicated in the description and the drawings. BRIEF DESCRIPTION OF THE DRAWINGS
