Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing, specifically relating to a structure for the cooperation between a steering column cover and a baffle. Background Technology

[0002] With the rapid pace of automotive upgrades, customers have increasingly stringent expectations for the sensory quality of vehicles. The steering column and dashboard beam are connected by a metal bracket, and the combination of functions in the steering column cover is constantly improving and increasing. This necessitates the addition of numerous support structures to the steering column, making the steering column cover crucial for shielding internal components. For light trucks, the connecting bracket between the steering column and the beam is positioned relatively high. Ordinary PVC soft covers only obscure the internal bracket from directly above, failing to cover the left and right sides of the column. Furthermore, the use of conventional injection-molded covers often results in a gap between the steering column cover and the actual cover, which worsens during four-way steering column adjustments, leading to a poor sensory experience. Therefore, a superior sensory design for the steering column cover and cover is needed to meet customer requirements. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a structure for the mating of a steering column upper cover and a retaining plate. This structure achieves effective mating and fixation between the cover and the retaining plate, thus optimizing the visual appearance. The specific technical solution is as follows:

[0004] A steering column upper cover and retainer mating structure includes three structural elements: a V-shaped groove, a rectangular hole, and a snap-fit ​​lug. The V-shaped groove is located at the bottom of the steering column upper cover's outer surface, extending from the left to the right side. The opening of the V-shaped groove is designed with a chamfered C-angle, and the internal clearance between the V-shaped groove and the retainer is 0.2mm, facilitating retainer assembly. This V-shaped groove completely hides the edge of the retainer and maintains the retainer's surface contour, ensuring consistency with the cover's surface. The rectangular holes are evenly distributed 10.5mm above the bottom of the steering column upper cover, ensuring the cover's strength during assembly. The snap-fit ​​lug extends from the back edge of the retainer; the snap-fit ​​lug is 17.8mm high, and the upper part of the rectangular hole has arc-shaped structures protruding from both sides of the snap-fit ​​lug, with a total width of 13mm and a thickness of 2.5mm. The snap-fit ​​lug structure fits snugly with the rectangular hole structure of the upper cover, effectively fixing the retainer. Simultaneously, the snap-fit ​​lug height facilitates direct finger operation, improving assembly efficiency.

[0005] Furthermore, the V-shaped groove has the following dimensions: 2mm wide at the opening, 1mm wide at the bottom, and 3mm deep.

[0006] Furthermore, the rectangular hole is 8.4mm long, 2mm wide, and 2.5mm deep.

[0007] Furthermore, the base of the branch ear is 8mm long, 2mm wide, and 2mm high.

[0008] The beneficial effects of this utility model are: the three mating structures enable the steering column cover and the shield to work together effectively, both shielding the internal components and concealing the gap between the cover and the shield to meet the customer's aesthetic requirements.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] A structure for the mating of a steering column cover and a brake pad, such as Figure 4 and Figure 6 As shown, the new type of steering column upper cover 1 and the shield 2 have three structural features: V-shaped groove 1-1, rectangular hole 1-2 and snap-fit ​​support lug 2-1 that fits into the hole.

[0020] like Figure 2 and Figure 3 As shown, the V-shaped groove 1-1 is located at the bottom of the guard 1 on the steering column and extends from the left side to the right side of the guard 1. The dimensions of the V-shaped groove 1-1 are: 2mm at the opening, 1mm at the bottom, and 3mm deep.

[0021] like Figure 3 As shown, the V-shaped groove 1-1 has a chamfered edge at the opening, and the V-shaped groove 1-1 fits with the side of the cover 2 with a 0.2mm gap on the other side, which makes it easier to assemble the cover 2.

[0022] like Figure 4 and Figure 5 As shown, the rectangular holes 1-2 on the steering column upper cover 1 are 8.4mm long, 2mm wide, and 2.5mm deep, and are evenly distributed at a position 10.5mm upward from the bottom of the steering column upper cover 1 to ensure the edge strength of the cover.

[0023] like Figure 6 and Figure 7 As shown, the snap-fit ​​support structure 2-1 is located at the edge of the retaining plate 2, extending from the back of the retaining plate 2. The total height of the snap-fit ​​support structure 2-1 is 17.8mm. The bottom is a rectangular structure with a length of 8mm, a width of 2mm, and a height of 2mm, which fits snugly with the rectangular hole structure 1-2 of the steering column upper cover 1. The upper part of the rectangular structure is an arc structure extending from both sides of the support structure 2-1, with a width of 13mm and a thickness of 2.5mm. The dimensions of the arc structure on both sides are larger than the dimensions of the rectangular hole, ensuring that the retaining plate 2 is effectively snapped onto the steering column upper cover 1. Figure 3 As shown, the inner dimension of the groove structure 1-1 of the cover 1 on the steering column is 2mm, which effectively hides the gap between the two.

[0024] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
