Description

Technical Field

[0001] The invention relates to the technical field of vehicle lamp masks, in particular to a multi-color vehicle lamp mask capable of preventing cracking. Background Art

[0002] The existing multi-color mask products for headlights have the following structure: Figure 1 As shown, the product is separated from the parting seam (3) by the upper light-transmitting member (1) and the lower light-transmitting member (2). The main disadvantages of this structure are: ①, the intersection of the black and white pieces is at the parting surface, the local glue position of the product is very sharp and thin, the PMMA flow length is short, the injection molding pressure is high, and after injection molding, the stress at the edge of the black and white pieces is very large. After assembly, annealing or encountering oily substances, the stress is released, and the edge of the black and white pieces is bright (cracked); ②, the parting line is at the intersection of the black and white pieces, and the gap is difficult to adjust during assembly and is unstable. Summary of the invention

[0003] The utility model aims to provide a multi-color cover for a headlight which can prevent cracking, and can solve the problem that the multi-color cover cracks due to large stress at the edge joint, thereby reducing the defective rate of injection molding and the defective rate of assembly.

[0004] In order to solve the above technical problems, the technical solution of the utility model is as follows: a multi-color mask for a car light that can prevent cracking, comprising a mask body, wherein the mask body is formed by bonding two layers of light-transmitting parts, the upper layer of which is a transparent part, the lower layer of which is a colored part, and the parting surface of the mask body is arranged at the lower end of the upper layer of the light-transmitting part.

[0005] Improvement on the above technical solution: a circular arc transition surface is provided at the lower end of the upper light-transmitting member of the mask body, and the parting surface is arranged on the circular arc transition surface.

[0006] Further improvement to the above technical solution: the light-transmitting member is PMMA transparent plastic.

[0007] Beneficial effects:

[0008] The multi-color face shield of the headlight that can prevent cracking described in the utility model is used. The parting surface of the face shield body is set at the lower end of the upper light-transmitting piece, which changes the product structure at the joint of the light-transmitting piece and avoids setting the parting surface at the joint edge where the light-transmitting piece intersects, which causes problems such as sharp glue and thin glue on the product. The utility model effectively solves the problem of product edge cracking; improves the problem of unstable gap face difference and inconvenient adjustment; the parting surface molding window of the utility model is wide, the injection molding process is easy to adjust, and the product quality is more stable, which effectively improves product quality, improves competitiveness, and reduces market claims.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 2 The utility model shown is a multi-color mask for a headlight capable of preventing cracking, comprising a mask body, wherein the mask body is formed by laminating two layers of light-transmitting parts, the upper light-transmitting part 1 being a transparent part, the lower light-transmitting part 2 being a colored part, and the parting surface 3 of the mask body being arranged at the lower end of the upper light-transmitting part 1.

[0015] The lower end of the upper light-transmitting member 1 of the mask body is provided with an arc transition surface, and the parting surface 3 is arranged on the arc transition surface.

[0016] The light-transmitting parts 1 and 2 are PMMA transparent plastic.

[0017] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
