Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an automobile steering column shield component. Background Art

[0002] The steering column of a car is a component of the steering system that connects the steering wheel and the steering gear. The driver transfers the torque to the steering gear through the steering column, which drives the steering gear to achieve steering. A steering column cover is usually provided on the outside of the steering column to cover the steering column and serve as a decoration. It moves with the steering column when it moves. The steering column cover of a car is generally composed of an upper cover and a lower cover, which wraps around the car's combination switch, ignition lock and other related circuits to protect them. The upper and lower covers are usually plastic parts, and the edges of the two have similar smooth matching requirements. If they are only fixed by the plastic clips themselves, the matching effect of the edges of the two cannot be guaranteed. Therefore, when manufacturers manufacture the upper and lower covers, they will set a clip-on structure on their inner walls. See Figure 1 The current clamping structure includes a clamping foot 26 provided at the edge of the lower shield 2 and a clamping seat 14 provided at the edge of the upper shield 1. A clamping hole is provided in the middle of the clamping seat 14, and the clamping foot 26 is inserted into the clamping hole to realize the clamping and fixing of the upper and lower shields. However, when this clamping structure is used for assembly, it is difficult to match smoothly in the matching area, and there are problems such as large local gaps and uneven surface differences. Moreover, this clamping structure can only limit the upper and lower shields in the Z direction, and the clamping force is weak. After long-term use, the upper and lower shields are prone to loosening, resulting in displacement of the connection. Utility Model Content
