[0016] In order to further explain the technical scheme of the present utility model, the present utility model is described in detail below through specific embodiments.

[0017] For example Figures 1-5As shown, the spring type scroll module of the steering wheel switch comprises a scroll support 105, a transmission gear 101, a shading gear 104 and a scroll 103. In the embodiment, the transmission gear 101 and the shading gear 104 are existing products. The transmission gear 101, the shading gear 104 and the scroll 103 are all rotationally installed on the scroll support 105, and the shading gear 104 is engaged with the transmission tooth one 103a of the scroll 103 and the transmission tooth two 104a of the shading gear 104. The spring 102 and the gear piece 106 are further included. The gear piece 106 is fixedly installed on the scroll 103 through axial sliding and circumferential fixing. The spring 102 is installed between the gear piece 106 and the scroll 103. In the embodiment, after assembly, the axis of the spring 102 coincides with the spool of the gear piece 106 and the spool of the scroll 103, so that the spring 102 has a larger installation space, thereby providing sufficient elastic force as needed. Through the spring 102, an outward force relative to the scroll 103 can be generated on the gear piece 106, so that when the scroll 103 is actuated, a corresponding damping effect is generated, and the positioning column 105a can be automatically clamped into the positioning recess 106a. The gear piece 106 has a plurality of positioning recesses 106a uniformly distributed in a ring shape on the outer side surface. The scroll support 105 has at least one positioning column 105a matched with the positioning recess 106a, and the positioning column 105a can be clamped into any one of the positioning recesses 106a. Specifically, the number of the positioning columns 105a is three, which are distributed in a three-point manner, so that when the scroll 103 is actuated, the scroll 103 rotates more stably and accurately under the cooperation of the three positioning columns 105a and the positioning recesses 106 of the gear piece 106, thereby greatly improving the comfort and accuracy of operation.

[0018] The scroll 103 has a plurality of small bosses 103b on the surface, thereby improving the grip and stability of the scroll 103 on various material surfaces.

[0019] The positioning recesses 106a form a wave-shaped structure in a ring shape.

[0020] The gear piece 106 is designed in the scroll 103 and connected with the spring 102, thereby improving the performance of the entire steering wheel switch and the comfort of user operation. The surface of the scroll 103 is designed with a plurality of small bosses 103b, thereby improving the grip and stability of the scroll 103 on various material surfaces, and further improving the overall performance. When the scroll 103 is actuated, the transmission tooth one 103a on one side of the scroll 103 drives the transmission gear 101, and the transmission gear 101 further drives the transmission tooth two 104a of the shading gear 104 below the scroll support 105 to rotate, thereby realizing the preset function operation and ensuring the linkage and function realization of the entire system. Through the above design, the user can feel unprecedented delicate feedback and smooth damping feeling, thereby improving customer satisfaction.

[0021] In summary, by designing a spring type roller module, the user can feel delicate feedback and smooth damping feeling during the rolling operation.

[0022] The above components are all general standard components or components known to those skilled in the art, and the structure and principle thereof can be known by the technical personnel through the technical manual or through the conventional experimental method.

[0023] The above embodiments and drawings are not limited to the product form and style of the utility model, and any appropriate changes or modifications made by those skilled in the art shall be considered as not departing from the patent category of the utility model.
