Description

Technical Field

[0001] This utility model relates to structural technology, specifically to a steering wheel connecting seat structure for an all-terrain vehicle. Background Technology

[0002] As an integrated carrier of the steering system and combination switch, the structural design of the all-terrain vehicle steering wheel connector directly affects the vehicle's handling and safety performance. Traditional connector structures suffer from the following technical drawbacks: ① Insufficient integration between the combination switch lever reset teeth and the insulating base, resulting in a large number of parts and poor compatibility; ② The connection method between the conductive module and the mechanical structure is singular, generally using integral welding or bolt connections, which suffers from defects such as loose conductive rings and unstable signal transmission; ③ The existing spline sleeve and connecting plate mating method fails to effectively balance mechanical strength and conductivity, posing a risk of breakage due to stress concentration. In particular, the traditional structure lacks modular design to meet the configuration requirements of different vehicle models (whether or not the combination switch function needs to be integrated), leading to the need for multiple molds on the production line and significantly increasing manufacturing costs. Furthermore, existing grounding line designs often use separate grounding terminals, which are prone to electrostatic interference under complex operating conditions. Therefore, a new all-terrain vehicle steering wheel connector structure is urgently needed to solve these problems. Utility Model Content

[0006] Firstly, the insulating base integrates the combination switch operating lever reset teeth.

[0007] Secondly, the insulating base lacks an integrated combination switch control lever reset tooth.

[0008] Preferably, the pad is connected to the connecting plate by welding, and the spline sleeve is disposed between the connecting plate and the insulating base.

[0014] (2) Improved conductivity stability: The pre-embedded conductive ring and the double wire welding structure (speaker signal line + grounding line) reduce the contact resistance;

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-3 As shown in the figure, the present invention provides a steering wheel connecting seat structure for an all-terrain vehicle, including a pad module 1 and a conductive module 2. The pad module 1 and the conductive module 2 are connected by four screws. The pad module 1 includes a pad 11, a connecting plate 12, and a spline sleeve 13. The conductive module 2 includes an insulating base 21. The insulating base 21 has two structures.

[0025] Firstly, the insulating base 21 integrates the combination switch operating lever reset tooth 23.

[0026] Secondly, the insulating base 21 does not have an integrated combination switch operating lever reset tooth 23.

[0027] With optional integrated / non-integrated insulating base configurations, the same platform can be adapted to meet the needs of different vehicle models.

[0028] Preferably, the pad 11 and the connecting plate 12 are connected by welding, and the spline sleeve 13 is set between the connecting plate 12 and the insulating base 21; by welding the pad and the connecting plate to form a rigid load-bearing body, and with the middle positioning structure of the spline sleeve, the steering wheel operating torque is effectively distributed, and the weld cracking caused by stress concentration is avoided.

[0029] Preferably, the upper end of the spline sleeve 13 is connected to the connecting plate 12 by welding, and the lower end of the spline sleeve 13 is connected to the insulating base 21 by transition fit; the welding at the upper end of the spline sleeve ensures mechanical strength, and the transition fit at the lower end ensures conductive contact area and allows for thermal expansion and contraction deformation compensation.

[0030] Preferably, the insulating base 21 is provided with a conductive ring 22, which is connected to the insulating base 21 as a whole by pre-embedding; the pre-embedding molding process improves the bonding strength between the conductive ring and the insulating substrate.

[0031] Preferably, at least one wire a is welded on the conductive ring 22, and the wire a is used to connect to the external horn switch a end through the connecting plate 12.

[0032] Preferably, the connecting plate 12 has at least one wire b welded to it, and the wire b is grounded.

[0034] A steering wheel connector structure for an all-terrain vehicle includes a pad module 1 and a conductive module 2, which are connected by four screws. The pad module 1 includes a pad 11, a connecting plate 12, and a spline sleeve 13, while the conductive module 2 includes an insulating base 21. The insulating base 21 has two possible structures.

[0037] Example 2

[0038] This embodiment further defines the previous embodiment. The pad 11 and the connecting plate 12 are connected by welding. The spline sleeve 13 is located between the connecting plate 12 and the insulating base 21. The welding connection between the pad and the connecting plate forms a rigid load-bearing body. With the intermediate positioning structure of the spline sleeve, the steering wheel operating torque is effectively distributed, avoiding weld cracking caused by stress concentration. The upper end of the spline sleeve 13 is connected to the connecting plate 12 by welding, and the lower end of the spline sleeve 13 is connected to the insulating base 21 by transition fit. The welding at the upper end of the spline sleeve ensures mechanical strength, and the transition fit at the lower end ensures conductive contact area and allows for thermal expansion and contraction deformation compensation. The insulating base 21 is provided with a conductive ring 22, which is pre-embedded and connected to the insulating base 21 as a whole. The pre-embedded molding process improves the bonding strength between the conductive ring and the insulating substrate. At least one wire a is welded on the conductive ring 22.
