Problems solved by technology

[0002] Existing car light products usually include a car light body and a car light cover. Due to differences in the color and material of the car light body, the laser beam will be damaged during the laser welding process between the car light body and the car light cover. If the absorption is not good, the melting layer in the lamp body and the lamp cover cannot be fully melted, which will affect the connection strength between the lamp body and the lamp cover after welding. The upper cover of the lamp is detached from the headlight lamp, which will bring great inconvenience to the driving process

Embodiment Construction

[0026] It should be noted that, in the case of no conflict, the following technical solutions and technical features can be combined with each other.

[0027] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0028] This embodiment provides a car lamp product, which is prepared by laser welding process, such as figure 1 shown, including:

[0029] The lamp upper cover and the lamp body, and the melting layer between the lamp upper cover and the lamp body;

[0030] Wherein, a laser absorbing solvent layer is coated on the melting layer, and the laser absorbing rate of the laser absorbing solvent layer is greater than that of the melting layer.

[0031] In the laser welding process, a laser device emits a laser beam, and the laser beam is irradiated onto the melting layer through the laser-absorbing solvent layer, so that the laser-absorbing solvent layer and the melting layer are melted to realize the l...

Abstract

The invention relates to the field of automotive lamp packaging, in particular to an automotive lamp product and a welding method thereof. According to the automotive lamp product and the welding method thereof, a fusion layer is coated with a laser absorption solvent layer, so that absorption for laser beams is enhanced; the fusion layer and the laser absorption solvent layer can be fused together completely; adhesion, between a lamp body of an automotive lamp and an upper cover of the automotive lamp, generated during laser welding is enhanced; and the upper cover of the automotive lamp is prevented from falling off the lamp body of the automotive lamp in the using process of an automotive lamp product.

Description

technical field [0001] The invention relates to the field of car lamp packaging, in particular to a car lamp product and a welding method thereof. Background technique [0002] Existing car light products usually include a car light body and a car light cover. Due to differences in the color and material of the car light body, the laser beam will be damaged during the laser welding process between the car light body and the car light cover. If the absorption is not good, the melting layer in the lamp body and the lamp cover cannot be fully melted, which will affect the connection strength between the lamp body and the lamp cover after welding. The light upper cover is detached from the car light lamp body, which brings great inconvenience to the driving process. Contents of the invention [0003] Aiming at the problems existing in the prior art, a car lamp product and its welding method are provided, which can enhance the absorption of the laser beam during the laser weld...
