Description

Technical Field

[0001] The present application relates to the technical field of vehicle lamps, and in particular to a structure for preventing corrosion and cracking of welding ribs of tail lamps. Background Art

[0002] At present, customers have higher and higher requirements on the life of automobiles, and the warranty period is getting longer and longer. For lamps, the requirements for aging durability are becoming more and more stringent, especially for taillights. The mask and lamp housing are mostly welded and sealed, and the welding ribs are exposed to the external environment. Under long-term rain and exposure corrosion, the strength of the welding ribs will gradually weaken. Under the long-term bumpy vibration of the vehicle, the welding ribs will crack, resulting in failure of the sealing of the entire lamp. In order to prevent the welding ribs from being corroded and cracked, we provide a structure to circumvent this problem. Utility Model Content

[0003] In order to make up for the above deficiencies, the present application provides a structure to prevent corrosion and cracking of the welding ribs of the taillights, aiming to improve the current situation where customers have higher and higher requirements on the life of the car and longer and longer warranty periods. For lamps, the requirements for aging and durability are also becoming more and more stringent, especially for taillights. The masks and lamp housings are mostly sealed by welding, and the welding ribs are exposed to the external environment. Under long-term rain and exposure to corrosion, the strength of the welding ribs will gradually weaken. Under long-term bumps and vibrations of the vehicle, cracks will occur at the welding ribs, resulting in failure of the sealing of the entire lamp.

[0004] This application is implemented as follows:

[0005] The present application provides a structure for preventing corrosion and cracking of taillight welding ribs, comprising a body sheet metal, a mask, soft glue, a lamp housing and a reflector, wherein the body sheet metal and the mask are both mounted on the lamp housing;

[0006] The reflector is arranged in the lamp housing, and the soft glue is arranged between the mask and the lamp housing.

[0007] In one embodiment of the present application, the mask includes an outer mask and an inner mask, the inner mask is fixed inside the outer mask, and the outer mask and the lamp housing are welded together.

[0008] In one embodiment of the present application, the soft glue is TPE soft glue.

[0009] In one embodiment of the present application, the lamp housing and the soft glue are formed by two-color injection molding.

[0010] The beneficial effect of the present application is: the present application obtains a structure for preventing the corrosion and cracking of the welding ribs of the taillights through the above-mentioned design. When in use, soft glue is added to the lamp housing, and the soft glue and the lamp housing are double-color injection molded to achieve local interference sealing with the mask. The soft glue seal covers the welding ribs to prevent the welding ribs from being exposed to the external environment. The structure for preventing the corrosion and cracking of the welding ribs of the taillights hides the welding ribs by adding soft glue to the lamp housing, which effectively prevents the welding ribs from being exposed to the external environment and ensures that the strength of the welding ribs will not weaken with the increase of time, which effectively prevents the welding ribs from cracking and increases the service life of the lamp.
