[0014] In order to further explain the technical scheme of the utility model, the utility model is described in detail below through specific embodiments.

[0015] As shown in the drawing, Figs. 1-3 The spring piece type roller module of the steering wheel switch includes a roller 100, a rotating tooth 101, a light shielding tooth 103, a roller shaft 104 and a roller support 105, and the roller 100, the rotating tooth 101, the light shielding tooth 103 and the roller shaft 104 are all rotationally installed on the roller support 105. In this embodiment, the roller support 105, the rotating tooth 101, the light shielding tooth 103 and the roller shaft 104 all adopt the existing structure. The rotating tooth 101 is engaged with the light shielding tooth 103 and also engaged with the tooth portion of the roller shaft 104. The roller shaft 104 is also connected with the roller 100. The roller 100 is further provided with a ring-shaped gear portion 100a on the side portion away from the rotating tooth 101. The gear portion 100a is arranged inside the roller 100. The gear portion 100a is provided with a plurality of positioning notches 100ax. The roller support 105 is further provided with a gear spring piece 102 matched with the gear portion 100a. The gear spring piece 102 is provided with a positioning convex portion 102x matched with the positioning notches 100ax.

[0016] The shape of the positioning convex portion 102x is U-shaped.

[0017] The shape of the gear spring piece 102 is L-shaped.

[0018] The roller 100 is provided with a connecting hole 100b connected with the roller shaft 104 on the other side away from the rotating tooth 101. In this embodiment, the gear portion 100a, the connecting hole 100b and the like on the roller 100 are all integrally formed with the body.

[0019] With the structure, the gear elastic sheet 102 is ingeniously assembled at the periphery of the roller support 105, and provides necessary tactile feedback and reset function through elastic deformation. In addition, the rotating tooth 101 is firmly fixed on the roller support 105, and is used to accurately capture and transfer the rotating action, so as to realize the conversion of electrical signal or the execution of mechanical function. When the user rotates the roller 100 to drive the roller shaft 104, the roller shaft 104 drives the rotating tooth 101, the rotating tooth 101 drives the light-shielding tooth 103, and the signal change is generated by the fan blades arranged on the light-shielding tooth 103 with the rotation of the roller 100. The change is accurately captured and converted into an electrical signal, so as to accurately detect the motion state or position information of the roller 100 in real time. The series of designs not only make the switch more reliable, but also ensure the accuracy of operation, and take into account the compactness of the structure and the rationality of the cost.

[0020] The above components are all general standard components or components known by those skilled in the art, and the structure and principle thereof can be known by those skilled in the art through a technical manual or through a conventional experimental method.

[0021] The above embodiments and drawings are not limited to the product form and style of the present application, and any appropriate changes or modifications made by those skilled in the art shall be considered as not departing from the scope of the present application.
