Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of steering wheel assembly, and particularly relates to a two-spoke steering wheel assembly and a vehicle. BACKGROUND

[0002] As an essential part of a vehicle, the steering wheel needs to solve the following problems in design and development:

[0003] 1. Arrangement space and weight problems:

[0004] In the prior art, the steering wheel bottom cover is mostly made of foaming material. This structure determines that the bottom cover is heavy and has a large thickness, thus occupying more internal space. In the foaming process, the foaming inlet is located below the handle bar portion, and the second foaming layer of the handle bar portion is small in thickness, which affects the flow rate of the foaming material and easily causes defects such as pores on the surface of the foaming bottom cover. For a light-colored bottom cover, the light resistance is prone to being unqualified. In addition, the decorative cover is connected with the bottom cover through multiple hooks, and it is difficult to completely disassemble the decorative cover and the switch, thus increasing the maintenance cost.

[0005] 2. Switch and wire harness fixation:

[0006] In the design of the steering wheel, the switch wire harness should be avoided from being pulled out during real vehicle assembly, so as to avoid the interference between the switch wire harness and the air bag, affect the horn function, and cause the wire harness to be damaged due to being clamped after the air bag is assembled. In the prior art, the root of the switch wire harness is fixed by a rolled tape or a tape with hooks, which increases the cost. In some vehicle models, the steering wheel adopts a wire harness slot, which is high in cost and increases the assembly time.

[0007] 3. Abnormal sound problem:

[0008] In the prior art, the switch is fixed with the decorative cover through multiple self-tapping nail connectors, and then assembled to the steering wheel foam through multiple hooks. Due to the existence of the activity amount of the clamping structure, the abnormal sound problem is easily caused by the floating of the switch when pressed.

[0009] 4. Exposed screw hole and air bag disassembly hole problem:

[0010] The screw hole (fastening switch and decorative cover) of some rear part of the steering wheel is close to the rim, which is easily touched by the driver, thus affecting the operation quality. The air bag disassembly hole of some steering wheels is located on the lower side of the left and right sides, which is easily seen by the driver, thus affecting the appearance quality.

[0011] 5. Steering wheel disassembly:

[0012] Some steering wheels are not designed with a structure for disassembling the steering wheel, so that the steering wheel cannot be disassembled after real vehicle assembly, and the steering column needs to be disassembled during maintenance, thus increasing the maintenance and maintenance cost. SUMMARY

[0013] In order to overcome the above problems, the present application provides a two-spoke steering wheel assembly and a vehicle, which saves space, cancels auxiliary fixing parts such as straps or buckles for fixing wire harnesses, reduces assembly difficulty, saves working hours, reduces cost, avoids different operation of switches, and makes the screw hole closer to the inner side of the steering wheel, so that it is not easy to be touched by the driver, thereby improving user experience.
