Description

Technical Field

[0001] This utility model relates to the field of steering wheel technology, and in particular to a steering wheel. Background Technology

[0002] As a crucial component in a car that directly interacts with the driver, the steering wheel is typically mounted on the vehicle using a positioning frame. Existing steering wheels consist of a one-piece die-cast rim, multiple spokes, and a hub. The rims are connected by multiple spokes, and during use, the steering wheel frame is fixed to the car's steering shaft through a hole in the center of the rim. For example, the utility model patent CN206501883U discloses a magnesium alloy steering wheel frame comprising a one-piece die-cast rim, spokes, and hub. Over prolonged use, the steering wheel, especially the spokes, experiences uneven pressure and torque. For instance, during sharp turns, rapid lane changes, or encountering bumpy roads, the steering wheel experiences significant and uneven forces. Over time, this can lead to fatigue damage, deformation, and even breakage of the spokes. Because the spokes, rim, and hub are a single, integrated structure, damaged spokes cannot be separated, making steering wheel repair inconvenient and potentially requiring the entire steering wheel to be scrapped, thus increasing maintenance costs. Utility Model Content

[0003] The purpose of this invention is to design a steering wheel that addresses the shortcomings of the aforementioned technologies. This steering wheel allows for individual spoke replacement instead of replacing the entire steering wheel, thereby effectively reducing maintenance costs and improving repair efficiency.

[0021] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0022] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A steering wheel includes a rim 1, a hub 2, a cover plate 4, and a number of spokes 3 evenly distributed in a circular array, with each spoke 3 having two ends detachably connected to the rim 1 and the hub 2, respectively.

[0023] The rim 1 includes a detachably connected support ring 11 and a protective ring 12. A fixing ring 101 is formed on the inner wall of the support ring 11. A movable hole 102 passes through the fixing ring 101 relative to the spoke 3. A movable groove 103 is formed on the inner wall of the opening of the movable hole 102. An adjusting sleeve 5 is inserted into and rotatably connected to the movable hole 102. An outwardly protruding portion 501 is formed on the outer wall of the first end of the adjusting sleeve 5. The outwardly protruding portion 501 is rotatably connected to the inner wall of the movable groove 103. The outwardly conical portion 501 abuts against the inner wall of the movable groove 103, thereby limiting the position of the adjusting sleeve 5. The second end of the adjusting sleeve 5 extends to the inner side of the rim 1 and forms an operating portion 502. The operating portion 502 has a square or regular hexagonal cross-section, allowing the user to use a wrench to clamp the operating portion 502 and rotate the adjusting sleeve 5. The protective ring 12 is fitted onto the outer wall of the fixed ring 101 to cover each movable hole 102, and the outer wall of the support ring 11 is adapted to the outer wall of the protective ring 12. The bottom of the support ring 11 has several grooves 104 arranged in a circular array. The grooves 104 are designed to better adapt to the driver's hand grip posture. When the driver grips the steering wheel, their fingers can naturally rest in the grooves 104. Preferably, at least two grooves 104 have mounting holes 105 on their inner walls for bolt connection, thereby fixing the support ring 11 and the protective ring 12 together with bolts.

[0024] The rim 1 is located above the hub 2. The first end of the spoke 3 is bent and provided with a first connector 301, and the second end of the spoke 3 is bent and provided with an L-shaped second connector 302.

[0025] The steering wheel is composed of a rim 1, a hub 2, a cover plate 4, and several spokes 3 evenly distributed in a circular array. A mounting ring 6 is detachably connected to the hub 2. A mating ring 201 is provided on the inner wall of the hub 2, and the mounting ring 6 is fitted onto the outer wall of the mating ring 201. A plug 401 is provided at the center of the cover plate 4, and the plug 401 is inserted into the inner wall of the mating ring 201, so that the cover plate 4 and the opposite side of the hub 2 cooperate to limit the mounting ring 6. A first limiting groove 7 is formed between adjacent mounting rings 6 and the hub 2 to limit the second connector 302, thereby limiting the second end of the spoke 3 on the hub 2. The first connector 301 is inserted and threaded into the adjusting sleeve 5. By rotating the adjusting sleeve 5, the first connector 301 is screwed in or out, thereby adjusting the tension of the spoke 3, so as to adjust the cushioning of the steering wheel as needed, thus adapting to the impact force generated by road bumps, the torque during steering, and other external forces. When spoke 3 is damaged, the user can separate the hub 2 and the mounting ring 6, and rotate the operating part 502 to rotate the adjusting sleeve 5, so that the spoke 3 can be unscrewed and disengaged from the adjusting groove, thereby achieving the separation of spoke 3. The steering wheel can replace the spoke 3 separately instead of replacing the entire steering wheel, which effectively reduces maintenance costs and improves maintenance efficiency.

[0026] Preferably, the spokes 3 are divided into two groups. The first connectors 301 of the spokes 3 in the first group and the first connectors 301 of the spokes 3 in the second group are adjacent and spaced apart. The second connectors 302 of the spokes 3 in the first group and the second connectors 302 of the spokes 3 in the second group are arranged vertically and staggered. This enhances the structural stability of the steering wheel, allowing it to better withstand and distribute stress, reducing excessive local stress, thereby reducing the risk of spoke damage and extending the service life of the steering wheel.

[0027] There are two mounting rings 6, arranged vertically and coaxially. The lower mounting ring 6 is detachably connected to the hub 2 by bolts. The two adjacent mounting rings 6 are also detachably connected by bolts. A second limiting groove 8 is formed between the opposite sides of the two adjacent mounting rings 6 to limit the second connector 302. The second connector 302 of the first group of spokes 3 is limited in the first limiting groove 7, and the second connector 302 of the second group of spokes 3 is limited in the second limiting groove 8.

[0028] Both the first limiting groove 7 and the second limiting groove 8 include a lower support groove 9, an upper support groove 10, and a slot 13 with its opening facing downwards. The slot 13 is formed on the inner wall of the upper support groove 10. The lower support groove 9 of the first limiting groove 7 is formed on the top surface of the hub 2, and the lower support groove 9 of the second limiting groove 8 is formed on the top surface of the mounting ring 6. The upper support groove 10 of the first limiting groove 7 and the upper support groove 10 of the second limiting groove 8 are respectively formed on the bottom surface of the two mounting rings 6. The cavity formed between the corresponding upper support groove 10 and lower support groove 9 is adapted to the second connector 302. The slot 13 is for the end of the second connector 302 to be inserted to limit the second end of the spoke 3.

[0029] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
