The composite structure consists of two parts that are joined together to enclose the rim frame.

[0003] The two parts of each segment of the existing composite structure are usually connected together by a plastic clip. Due to the constraints of plastic materials and internal space, the strength and rigidity of the plastic clip connection are limited. When the steering wheel is held, there is a possibility of squeezing or twisting between the two parts of the composite structure. At this time, there will be a certain amount of friction or relative movement at the overlapping interface of the plastic clip, thereby generating noise and causing discomfort to the user.

[0026] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings and described in detail.

[0027] like Figure 1A 、 Figure 1B and Figure 2 As shown, the existing steering wheel includes a skeleton 100 and a composite structure 200. The skeleton 100 includes a rim skeleton 110, a spoke skeleton 120 and a hub skeleton 130. The hub skeleton 130 is used to be connected to the steering column. The spoke skeleton 120 is respectively connected to the rim skeleton 110 and the hub skeleton 130. The composite structure 200 is wrapped around the outside of the rim skeleton 110. The outsides of the spoke skeleton 120 and the hub skeleton 130 are covered with decorative parts 300. The composite structure 200 includes a first part 210 and a second part 220. The first part 210 and the second part 220 match each other and can be detachably connected. After the first part 210 and the second part 220 are connected, a space will be formed between the two. The rim skeleton 110 can be located in the space, thereby achieving the wrapping of the rim skeleton 110. The first part 210 and the second part 220 are only connected together by a plurality of snap structures 230, and after being connected, there is no fastening connection between the first part 210 and the second part 220 and the wheel frame 110. Figure 2 When twisted or pressed in the direction indicated by the middle arrow, the snap structure 230 may produce abnormal friction noise; and when the steering wheel collides, the snap structure 230 may break due to insufficient strength, resulting in separation between the first part 210 and the second part 220 and the generation of fragments. Figure 1A and Figure 1B This is a schematic diagram of the structure of the steering wheel and frame that the driver sees when sitting in the driver's seat and facing the steering wheel.

[0028] In order to solve the above problems in the prior art, Figure 3As shown, the utility model provides a steering wheel, which, on the basis of the existing steering wheel, adds a fixing column 240 on the inner side of the first part 210 or the second part 220 (the side close to the rim frame 110), and the fixing column 240 is fixed to the rim frame 110 by a fastener 250. In this way, when the steering wheel is twisted or pressed, since the first part 210 is fastened to the rim frame 110, the first part 210 will remain stationary and the snap structure 230 will not produce friction noise; and since the fastener 250 has a higher connection strength, even if the steering wheel collides, the fastener 250 will not break, so the overall strength of the steering wheel can be improved, preventing the first part 210 and the second part 220 from separating after the steering wheel collides.

[0029] In some embodiments, fastener 250 may be a screw, a rivet, or any other suitable fastening element.

[0030] The number of the fixing columns 240 can be set as needed, for example, 1, 2, 3 or more; when the number of the fixing columns 240 is multiple, the fixing columns 240 can be evenly arranged along the circumference, such as Figure 4 For example, under the premise of ensuring strength, a fixing column 240 can be set at every 15 mm interval.

[0031] In some embodiments, both the first portion 210 and the second portion 220 are formed into a multi-layer composite structure, each including a support layer, a functional layer, and an exterior layer sequentially connected from the inside out. For example, the first portion 210 includes a support layer 211, a functional layer 212, and an exterior layer 213, while the second portion 220 includes a support layer 221, a functional layer 222, and an exterior layer 223. The support layer can be made of a plastic material such as acrylonitrile butadiene styrene plastic, polycarbonate, or polyamide to form a hard layer. The functional layer can be cushioned with various required functions, such as hand-off detection, heating, and lighting. The exterior layer can be made of a soft material (such as a thermoplastic elastomer, fabric, animal skin, or artificial leather) to form a soft layer, thereby providing the steering wheel with a more aesthetically pleasing appearance and a more comfortable feel. The fixing post 240 can be formed on the support layer of either the first portion 210 or the second portion 220.

[0032] Figure 3 The assembly process of the steering wheel is as follows:

[0033] First, the part with the fixing column 240, such as the first part 210, is assembled to the wheel rim frame 110. Pre-positioning structures can be set on the wheel rim frame 110 and the first part 210, so that the fixing column 240 can be pre-positioned with the wheel rim frame 110; then, the fixing column 240 is fastened to the wheel rim frame 110 by the fastener 250. For example, when the fastener 250 is a screw, screw holes are provided on the fixing column 240 and the wheel rim frame 110. When pre-positioning, the screw holes of the two need to be aligned. When tightening, the screw passes through the screw holes of the two and is tightened to achieve tightening; finally, the second part 220 and the first part 210 are assembled by the snap-fit ​​structure 230 ( Figure 3 The buckle structure 230 is not shown in FIG. Figure 2 ) snap together to complete the assembly.

[0034] In some embodiments, the fixing post 240 can also be fixed to the wheel rim frame 110 by welding. Figure 5 As shown, the fixing column 240 can be a solid structure and directly welded to the wheel rim frame 110; or as shown in FIG. Figure 6 As shown, the fixing column 240 can be a hollow structure having a cavity 241 , and the rim frame 110 is located in the cavity 241 so that the fixing column 240 wraps the rim frame 110 , thereby making the fixing column 240 and the rim frame 110 more firmly fixed.

[0035] Figure 5 The assembly process of the steering wheel is as follows:

[0036] First, the part with the fixing column 240, such as the second part 220, is assembled to the wheel rim frame 110. The wheel rim frame 110 and the second part 220 can be provided with a pre-positioning structure so that the fixing column 240 can be pre-positioned with the wheel rim frame 110; then the fixing column 240 and the wheel rim frame 110 are welded together; finally, the second part 220 and the first part 210 are connected by the snap structure 230 ( Figure 5 The buckle structure 230 is not shown in FIG. Figure 2 The wheel rim frame 110 may be provided with a through hole, and during pre-positioning, the fixing post 240 may pass through the wheel rim frame 110 through the through hole. During welding, the side arms of the fixing post 240 are welded to the wheel rim frame 110, thereby making the connection strength higher.

[0037] Figure 6 The assembly process of the steering wheel is as follows:

[0038] The second part 220 is pre-equipped with two side arms 242 of the fixing column 240. The second part 220 is first assembled to the wheel rim frame 110. During assembly, the wheel rim frame 110 is located between the two side arms 242. Then, the two side arms 242 are welded to the wheel rim frame 110, and a connecting arm 243 is welded between the two side arms 242. The two side arms 242 are connected together by the connecting arm 243, and the inner cavity 241 of the fixing column 240 is formed into a closed cavity to wrap the wheel rim frame 110. Finally, the second part 220 and the first part 210 are assembled together through the snap structure 230 ( Figure 6 The buckle structure 230 is not shown in FIG. Figure 2 ) snap together to complete the assembly.

[0039] exist Figure 3 、 Figure 5 and Figure 6 In the steering wheel shown, the first portion 210 and the second portion 220 are spliced ​​left and right, that is, in the cross-sectional view, the first portion 210 is located on the right side of the rim frame 110, and the second portion 220 is located on the left side of the rim frame 110. In some embodiments, as shown in FIG. Figure 7 、 Figure 8 and Figure 9 As shown, the first part 210 and the second part 220 can also be spliced ​​up and down, that is, in the cross-sectional view, the first part 210 is located above the rim frame 110, and the second part 220 is located below the rim frame 110, which is the same as the left and right spliced ​​steering wheel. The fixing column 240 can be arranged on the first part 210 or the second part 220, and the fixing column 240 can be fixedly connected to the rim frame 110 by a screw 250, or welded to the rim frame 110.

[0040] In some embodiments, the first part 210 and the second part 220 can also be composed of multiple identical segments respectively, and each segment of the first part 210 corresponds one-to-one to each segment of the second part 220 and matches each other. In this way, the composite structure 200 can be divided into multiple segments, each segment is independent, and can integrate different functional modules and adopt different appearance designs, thereby improving the flexibility and personalization of the steering wheel product. At the same time, the segmented design can also make the assembly and maintenance of the steering wheel simpler, which helps to reduce production and maintenance costs.

[0041] In the steering wheel of the embodiment of the present invention, a fixing column 240 is provided on the first part 210 or the second part 220 of the composite structure 200. The fixing column 240 is fastened to the rim frame 110, thereby preventing the snap structure 230 from making abnormal friction noise when the steering wheel is twisted or pressed. At the same time, it can also improve the overall strength of the steering wheel and prevent the first part 210 and the second part 220 from separating after a collision of the steering wheel.
