Technical Field

The invention relates to a novel waterproof and dustproof mechanism of an automobile door lock, and belongs to the field of automobile door structures.

Technical Field

With the development of the whole automobile technology, the requirement on the overall performance of an automobile door assembly is continuously improved, and the automobile side door lock is also put forward higher requirements by current customers as a safety piece for ensuring the running safety of the automobile. When the automobile is in the weather of washing or rain and snow, water can flow into between the inner plate and the outer plate of the automobile door from the glass, the outer water blocking plate and the mud groove, the water entering the inner metal plate and the outer metal plate of the automobile door can flow downwards along the fixed guide rail, the waterproof reliability of the existing automobile door lock waterproof mechanism is not high, the shell is easy to feed water into the seam, and the electric mechanism inside the lock body is easy to generate short circuit after water is fed, so that certain failure rate is caused.

Disclosure of Invention

The invention aims to overcome the defects and provide a novel waterproof and dustproof mechanism for an automobile door lock, which has good sealing performance, does not cause short circuit of a motor and influence the function of the motor, and has good dustproof performance.

According to the technical scheme provided by the invention, the novel waterproof and dustproof mechanism for the automobile door lock comprises an upper box body, wherein a box cover module is arranged on the upper box body, the box cover module is fixed with the box body in a laser welding mode, and the box cover module comprises a motor box cover, a double-connection gear box cover and a transmission gear box cover. The box cover module is connected with the upper box body through a welding line; and the upper box body is provided with a gear transmission assembly.

Furthermore, the gear transmission assembly comprises a motor, a motor gear, a duplicate gear, a transmission gear, a locking linkage arm and a locking rocker arm, the motor is coaxially connected with the motor gear, the motor gear drives the duplicate gear and then is connected with the transmission gear, and the transmission gear, the locking linkage arm and the locking rocker arm are sequentially connected.

Further, a sealing ring is arranged at the bottom of the transmission gear.

The invention has the advantages of simple and compact structure; the water that gets into the inside and outside panel beating of door even through the lock, also has fine leakproofness, can not cause the motor short circuit, influences its function, simultaneously, has fine dirt proofness.

Detailed Description

The invention is further elucidated below in accordance with the drawings.

As shown in fig. 1-2, a novel waterproof and dustproof mechanism for an automobile door lock comprises an upper box body 1, wherein a box cover module 10 is arranged on the upper box body 1, the box cover module 10 is fixed with the upper box body 1 by laser welding, and the box cover module 10 comprises a motor box cover 9, a double-link gear box cover 12 and a transmission gear box cover 13; the box cover module 10 is connected with the upper box body 1 through a welding line 11.

The upper box body 1 is provided with a gear transmission assembly, and the gear transmission assembly comprises a motor 2, a motor gear 3, a duplicate gear 4, a transmission gear 5, a locking linkage arm 7 and a locking rocker arm 8. The motor 2 is coaxially connected with a motor gear 3, the motor gear 3 drives a duplicate gear 4 and then is connected with a transmission gear 5, and the transmission gear 5, the locking linkage arm 7 and the locking rocker arm 8 are sequentially connected. And a sealing ring 6 is arranged at the bottom of the transmission gear 5.

In the use process of the invention, firstly, the laser welding of the box cover module 10 ensures that the welding line does not leak water, and secondly, the sealing ring 6 is arranged at the bottom of the transmission gear 5, so that water splash can be prevented from splashing into the gear from the outside, and meanwhile, dust can be prevented from entering, and further, the control circuit is prevented from being influenced.
