Problems solved by technology

[0002] The current structure of the light distribution mirror is mainly composed of two entities bonded to each other on one side. During the production and use of the lamp, due to the influence of various objective conditions on the lamp, it is easy to crack at the joint of the two entities, resulting in the failure of the lamp. The poor appearance of the product and the poor airtightness of the product cause water leakage, which directly affects the quality of the lamp and the pass rate of the product, and the product cost increases accordingly, resulting in weakened market competitiveness.

Embodiment Construction

[0007] Depend on figure 1 It is well known that the light distribution mirror cover of this embodiment has a structure to prevent cracking, and the mold of the injection molding machine is molded and injected, and the light distribution mirror 1 and the injection molded light distribution mirror 2 will be integrated with each other. A flange structure 3 is added around the mirror. The size of the rib is 1 mm×1mm. The injection molded light distribution mirror 2 has a groove, and the light distribution mirror flange 3 is inserted into the groove of the injection molded light distribution mirror 2. During production and use During the process, the lamps and lanterns will be affected by forces from various aspects. The structure light distribution mirror of the present invention is red 2, and the injection molding light distribution mirror 2 is white. This structure reduces product cracking, improves product quality and qualified rate, and reduces cost.

Abstract

The invention relates to a cracking-prevention structure suited on a lens, which consists of the lens (1) and an injection-molding lens (2), wherein the lens (1) is provided with a flange (3), the injection-molding lens (2) is provided with a rove, the flange (3) of the lens (1) is clamped into the groove of the injection-molding lens (2); the cracking-prevention structure is characterized in that: the flange (3) of the lens (1) is a reinforcing rib. In the invention, the contact area of the two lenses can be directly increased, the stressed force in a unit area is reduced, the air tightness of a lamp is effectively improved, the cracking is prevented, and the yield of the products is improved to 93.7% from 75.2 percent.

Description

technical field [0001] The invention relates to the industry of automobile lamps, in particular to a crack-preventing structure for a light distribution lens cover of an automobile lamp. Background technique [0002] The current structure of the light distribution mirror is mainly composed of two entities bonded to each other on one side. During the production and use of the lamp, due to the influence of various objective conditions on the lamp, it is easy to crack at the joint of the two entities, resulting in the failure of the lamp. The poor appearance of the lamp and the poor airtightness of the product cause water leakage, which directly affects the quality of the lamp and the pass rate of the product, and the product cost increases accordingly, resulting in weakened market competitiveness. Contents of the invention [0003] In view of the above deficiencies, the object of the present invention is to provide a cover-type structure for the light distribution mirror of ...
