Referring to fig. 2 to fig. 5, in the present embodiment, the circuit board 20 includes two shifting blocks 21, and the two shifting blocks 21 are disposed at an interval on a surface of the circuit board 20 facing the switch mechanism 30. The switch mechanism 30 cooperates with the two blocks 21 to make menu selections.

The switch mechanism 30 includes a supporting plate 31 and a rotating component 32, the supporting plate 31 is fixedly connected to the housing 10, and the rotating component 32 is rotatably mounted on the supporting plate 31. Specifically, the carrier plate 31 is substantially circular, and the outer diameter of the carrier plate 31 is slightly larger than the aperture of the mounting hole 11 of the housing 10, so as to facilitate the outer edge of the carrier plate 31 to be attached to the surface of the housing 10 facing the circuit board 20.

In the present embodiment, a switch hole 311 is opened at a position near the center of the carrier plate 31. The rotating assembly 32 includes a rotating plate 321, a rotating touch plate 322, a first limiting ring 323 and a supporting block 324. The turntable 321 includes an outer rotor 3211, an inner rotor 3212, and an adapter 3213. The adapter 3213 connects the outer rotor 3211 and the inner rotor 3212. The adaptor 3213 is substantially annular, and has an outer diameter that matches the diameter of the adaptor hole 311, so that the adaptor 3213 is rotatably received in the adaptor hole 311. The outer rotors 3211 are substantially circular plate-shaped, and the outer diameter of the outer rotor 3211 matches the diameter of the assembly hole 11 of the housing 10, so that the outer rotor 3211 can be rotatably received in the assembly hole 11 and supported above the supporting plate 31.

The inner rotor 3212 is substantially a circular plate-shaped structure, and an outer diameter of the inner rotor 3212 is slightly larger than an inner diameter of the outer rotor 3211, so as to facilitate the connection between the outer rotor 3211 and the inner rotor 3212 by the adaptor 3213. The inner rotator 3212 is recessed toward a surface of the circuit board 20 opposite to the outer rotator 3211, and the outer rotator 3211 and the inner rotator 3212 are parallel to each other.

The first limiting ring 323 is sleeved on the outer peripheral side wall of the inner rotating body 3212 and is fixedly connected to the adapting portion 3213. The outer edge of the first position-limiting ring 323 protrudes outward to form the adapter 3213, and abuts against a surface of the supporting plate 31 facing away from the outer rotor 3211, so as to cooperate with the outer rotor 3211 to limit the adapter 3213 in the adapter hole 311 of the supporting plate 31, thereby allowing the turntable 321 to be rotatably and stably mounted on the supporting plate 31.

The inner rotary body 3212 is provided with a plurality of rotating legs 3215 along an outer edge of a surface facing the circuit board 20 at intervals, so that when the rotary plate 321 rotates, the plurality of rotating legs 3215 sequentially move the two moving blocks 21 on the circuit board 20, and input a corresponding menu selection command to the circuit board 20 according to a predetermined rule.

In this embodiment, the outer rotor 3211 is provided with a retaining ring 3217 protruding along a surface of the outer rotor facing away from the supporting plate 31 and along the outer edge and the inner edge.

Preferably, the rotating touch sheet 322 is made of a metal, or glass material, but is not limited thereto. In this embodiment, a CD stripe (not shown) is disposed on a surface of the rotating touch pad 322 facing away from the outer rotator 3211 to improve a touch feeling of the user on the rotating touch pad 322.

An annular groove 312 is formed on a surface of the carrier plate 31 away from the circuit board 20 and corresponding to the outer rotor 3211. The supporting block 324 is fixed at the bottom of the annular groove 312 for elastically supporting the outer rotor 3211 and preventing the outer rotor 3211 from shaking during rotation. In the present embodiment, the supporting block 324 is substantially circular, and the outer diameter of the supporting block 324 is slightly smaller than the outer diameter of the annular groove 312, so that the supporting block 324 is received in the annular groove 312 and stably supported on the outer body 3211.

Preferably, the support block 324 is a foam. Because the foam has elastic properties, when a user manually dials the rotating touch piece 322 to rotate, the friction between the fingers of the user and the rotating touch piece 322 can be increased, and the outer rotor 3211 can be conveniently dialed by the fingers to rotate. The user generally needs to press the rotating touch piece 322 towards the direction of the bearing plate 31 in the process of stirring the rotating touch piece 322 to rotate, at this moment, the supporting block 324 is pressed and deformed, and meanwhile, the elastic restoring force of the supporting block 324 is further fed back to the user, so that the hand feeling is effectively improved.

It is understood that a teflon layer (not shown) is formed on a surface of the supporting block 324 facing the outer body 3211, and the teflon layer is made of Polytetrafluoroethylene (PTFE) to enhance wear resistance of the supporting block 324, but is not limited thereto.
