Description

Technical Field

[0001] The invention relates to the technical field of automobile steering wheels, and in particular to a platform-based automobile steering wheel skeleton with expandable functions. Background Art

[0002] The car steering wheel is a device used to control the driving direction. With the improvement of people's living standards, more and more families have begun to own private cars. Customers' requirements for the configuration of steering wheels have gradually increased, and they are in urgent need of a steering wheel with rich configurations. At present, the vehicle manufacturer needs to redesign the structure of the steering wheel frame every time it adds a function to the steering wheel, which increases the development time, increases the production cost, and makes it difficult to control product quality. Summary of the invention

[0003] The purpose of the present invention is to provide a platform-based automobile steering wheel framework with expandable functions in order to solve the above-mentioned problems.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0005] A platform-based automobile steering wheel skeleton with expandable functions comprises a steering wheel skeleton, the steering wheel skeleton is approximately disc-shaped, a first mounting hole is arranged at the center of the steering wheel skeleton, a first through hole, a first boss and a second through hole are arranged in sequence near one end of the steering wheel skeleton, a third through hole, a second boss and a fourth through hole are arranged in sequence near the other end of the steering wheel skeleton, the first through hole, the first boss and the second through hole are symmetrically distributed with the fourth through hole, the second boss and the third through hole respectively with the center of the steering wheel skeleton as the symmetry center, positioning blocks are arranged in the first through hole, the second through hole, the third through hole and the fourth through hole, the second boss and the second boss are arranged in the first boss and the second boss, and a shift paddle plug-in is arranged in the fourth through hole; a groove is arranged near one side of the steering wheel skeleton, an airbag and a multi-function switch plug-in are arranged in the groove, a fifth through hole is arranged near the other side of the steering wheel skeleton, and an electric heating steering wheel plug-in is arranged in the fifth through hole; a first tie hole is arranged on one side of the groove, a second tie hole is arranged on one side of the first mounting hole, and a third tie hole is arranged on the other side of the first mounting hole; a first bracket and a second bracket are arranged at positions corresponding to the fifth through hole in the circumferential direction of the steering wheel skeleton. The first through hole, the second through hole, the third through hole and the fourth through hole support the shift paddle function. The positioning block is used to position and install the shift paddle. The shift paddle plug-in is connected to the clock spring to realize the power supply of the shift paddle. The second mounting hole on the first boss and the second boss is used to fix the shift paddle. The airbag and multi-function switch plug-in is compatible with the functions of the airbag and the multi-function switch. The electric heating steering wheel plug-in is compatible with the electric heating function. The first tie hole, the second tie hole and the third tie hole meet the wiring harness fixation of different functional devices, avoiding the abnormal noise problem caused by the unfixed wiring harness. When the car passes through bumpy roads and rough roads, it is easy to cause abnormal noise inside the steering wheel, so the wiring harness inside the steering wheel needs to be fixed.

[0006] Preferably, the cross section of the positioning block is T-shaped. The positioning block is accurately positioned and the shift paddle has good stability.

[0007] Preferably, the first bracket and the second bracket are symmetrically distributed with the center of the steering wheel skeleton as the symmetry center.

[0008] Preferably, the first bracket and the second bracket are both provided with a third mounting hole near the end portion, wherein the third mounting hole can be used to fix a vibration motor to support the vibration function of the steering wheel.

[0009] Preferably, the first bracket and the second bracket are both integrally formed with the steering wheel frame. The first bracket and the second bracket enhance the structural strength of the steering wheel frame.

[0010] Preferably, spare tie holes are provided near both ends of the fifth through hole.

[0011] As the functions of the steering wheel increase, the structure of the clock spring will become correspondingly complex. To meet compatibility, the structure of the steering wheel frame also takes into account the matching structural design with the clock spring to meet matching requirements.

[0012] The beneficial effects of the present invention are: airbags, multi-function switches, shift paddles, electric heating and vibration functions can be added to the steering wheel frame of the present invention at the same time to meet people's usage needs; at the same time, spare cable tie holes are reserved, and one or two new functions can be further expanded in the later stage, which has high flexibility in use; the steering wheel frame has good compatibility and does not need to be redesigned and manufactured according to different functions, which shortens the research and development cycle and reduces development costs; the steering wheel frame has strong versatility, stable quality and high reliability.
