Description

Technical Field

[0001] This utility model relates to the field of protective structures, and in particular to a car door lock protective structure. Background Technology

[0002] Car door locks are one of the core safety components of a car body. Their main function is to control the opening and closing of the doors, while ensuring the safety of people and property during parking and driving. They also have additional functions such as preventing accidental operation (e.g., the door opens unexpectedly while driving) and preventing theft. Their technology has gradually evolved from traditional mechanical structures to electronic control.

[0003] The existing door lock latch structure is usually directly connected to the B-pillar of the vehicle body during installation. The connection method is usually to fix it with bolts. However, after installation, the bolts will be exposed to the outside for a long time, and dust will easily accumulate on the outer surface of the bolts. At the same time, the bolts are also prone to wear during long-term closing of the door. Once the bolt surface is covered with dust or damaged, it will increase the difficulty of disassembling the latch structure.

[0004] Therefore, those skilled in the art have provided a door lock protection structure to solve the problems mentioned in the background art. Utility Model Content
