Description

Technical Field

[0001] This utility model relates to the structure of an automobile steering wheel, and in particular to a steering wheel support cover structure. Background Technology

[0002] As is well known, traditional automotive steering wheel rims typically consist of a frame supported by a polyurethane foam layer, with a leather layer covering the outside of the foam. During production, the foam surface is prone to scorching and peeling, while internal defects include hidden bubbles and incomplete filling. Subsequent manual trimming of the foam edges is highly susceptible to human error, resulting in a persistently high defect rate and relatively high manufacturing costs. The final product significantly impacts the vehicle's odor and the emission of volatile organic compounds. Although steering wheel manufacturing is continuously optimizing processes and selecting environmentally friendly materials, these problems have not yet been effectively resolved. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a foam layer that can replace the steering wheel, and a steering wheel support cover structure that is simple in structure, easy to install and firm.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A steering wheel support cover structure includes a steering wheel frame, with multiple mounting holes on the rim of the steering wheel frame, an upper support cover and a lower support cover on the upper and lower parts of the steering wheel frame respectively, and an upper hook and a lower hook in the annular groove of the upper and lower support covers respectively. Two lower hooks are arranged symmetrically in pairs and correspond to one mounting hole. Each pair of lower hooks passes through the corresponding mounting hole by inward elastic deformation, and after rebounding, it is locked onto the upper edge of the corresponding mounting hole by the retaining edge at its outer upper end. The upper hook has two symmetrical hook bodies at its lower end. The two hook bodies are inserted into the two lower hooks arranged in pairs by elastic deformation inward, and are respectively inserted into the slots provided at the lower part of each lower hook, so as to realize the engagement of the upper and lower support covers with the steering wheel frame.

[0005] As a further preferred option, the inner sides of the two lower hooks arranged in pairs are provided with a pair of stiffening plates on both sides of the slot, and a vertically arranged slide is formed between the pair of stiffening plates so that the two hook bodies of the upper hook can be accurately inserted into the slot during installation.

[0006] As a further preferred embodiment, the lower end of the upper hook is provided with a V-shaped groove to achieve elastic deformation of the two hook bodies.

[0007] As a further preferred embodiment, the upper part of the upper hook is a rectangular strip with a width that closely matches the inner gap of the two lower hooks arranged in pairs, so as to abut each pair of lower hooks against the two ends of the corresponding mounting hole.

[0008] As a further preferred embodiment, both the upper support cover and the lower support cover are injection molded from rigid materials.

[0009] The beneficial effects of this utility model are as follows: 1. By interlocking the upper hook on the upper support cover and the lower hook on the lower support cover into the corresponding mounting holes, the foam layer of the steering wheel can be replaced to wrap the steering wheel frame. The structure is simple, easy and secure to install, which can improve the product qualification rate and reduce manufacturing costs.

[0010] 2. Since both the upper and lower support covers are injection molded from rigid materials, the odor of the product can be eliminated by selecting environmentally friendly materials for injection molding. Attached Figure Description

[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 scope of protection of the present utility model.

[0019] like Figure 1-6As shown, the present invention relates to a steering wheel support cover structure, including a steering wheel frame 1, which is a hard injection molded part or a die-cast part, used to support the main structure of the steering wheel; a plurality of rectangular mounting holes 101 are evenly distributed on the rim of the steering wheel frame 1; an upper support cover 2 and a lower support cover 3 are respectively provided on the upper and lower surfaces of the steering wheel frame 1; annular grooves are respectively provided on the opposite surfaces of the upper support cover 2 and the lower support cover 3, forming an annular cavity to fasten the steering wheel frame 1 therein.

[0020] Upper hook 4 and lower hook 5 are respectively provided in the annular groove of the upper and lower support covers. Two lower hooks 5 are arranged symmetrically in pairs in the annular groove of the lower support cover 3 and correspond to a mounting hole 101. Each pair of lower hooks 5 passes through the corresponding mounting hole 101 through inward elastic deformation, and after rebounding, they are locked on the upper edge of the corresponding mounting hole 101 through the retaining edge at the upper end of their outer side.

[0021] The upper hook 4 has two symmetrically arranged hook bodies 401 at its lower end. The two hook bodies 401 are inserted into the two paired lower hooks 5 by elastically deforming inward, and after rebounding, they are respectively inserted into the rectangular slots 501 located at the lower part of each lower hook 5, so as to realize the engagement of the upper and lower support covers with the steering wheel frame 1. The locking edges of the two hook bodies 401 are respectively locked into the upper edge of the corresponding slots 501 to ensure a firm engagement.

[0022] The upper hook 4 has a V-shaped groove 402 at the lower center to allow for elastic deformation of the two hook bodies 401. The upper part of the upper hook 4 is a rectangular strip with a width that fits closely with the inner gap of the two lower hooks 5 arranged in pairs, so as to press each pair of lower hooks 5 against the two ends of the corresponding mounting holes 101.

[0023] A pair of reinforcing plates 6 are provided on the inner side of the two lower hooks 5 arranged in pairs, located on both sides of the slot 501. A vertically arranged slide is formed between the pair of reinforcing plates 6. The thickness of the upper hook 4 is matched with the width of the slide to ensure that the two hook bodies 401 of the upper hook 4 are accurately inserted into the slot 501 during installation.

[0024] Both the upper support cover 2 and the lower support cover 3 are injection molded from rigid materials.

[0025] During installation, insert each pair of lower hooks 5 on the lower support cover 3 into the mounting holes 101 on the steering wheel frame 1 simultaneously from bottom to top until each pair of lower hooks 5 is engaged at the upper edge of the corresponding mounting hole 101; then align the upper hooks 4 on the upper support cover 2 with each pair of lower hooks 5 on the lower support cover 3 and press down, so that the two hook bodies 401 at the lower end of each upper hook 4 elastically deform and slide down along the slide until they are engaged in the rectangular slots 501 at the lower part of each lower hook 5, thus completing the installation of the upper and lower support covers and fastening the steering wheel frame 1 in them.

[0026] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
