Detailed ways

In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose, the specific implementation of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

Referring to FIGS. 1 to 3 , an embodiment of the present invention provides a photoelectric driven rotary switch, which includes a positioning base 2 and a rotating base 9 disposed on the positioning base 2 . Several stoppers 92 are distributed; a PCB board 10 is arranged on the positioning base 2 , and a photoelectric switch 101 corresponding to the several stoppers 92 is arranged on the PCB board 10 . Specifically, the photoelectric switch 101 may be a U-shaped transmission photoelectric switch or a reflective photoelectric switch.

When the rotating base 9 is rotated, the photoelectric switch 101 and the several blocks 92 in the rotating base 9 will generate an information source. Specifically, when the rotating base 9 is rotated, several blocks 92 in the rotating base 9 rotate along with it, and since the positioning base 2 is stationary, the photoelectric switch 101 is also stationary. Therefore, when the rotating base 9 rotates until one of the stoppers 92 is located between the photoelectric switches 101, the light of the photoelectric switch 101 is blocked by the stoppers 92, and a signal is output to the PCB board 10; when the rotating base 9 rotates to no stop When the block 92 is located between the photoelectric switches 101 , that is, the photoelectric switch 101 is located between two adjacent blocks 92 , and the light of the photoelectric switch 101 is not blocked, another signal is output to the PCB board 10 .

Therefore, when the rotary base 9 is rotated by 360°, the photoelectric switch 101 and several stops 92 in the rotary base 9 generate different signals, and send signals to the PCB board 10, so that different functions can be defined, such as volume adjustment, menu select etc.

At the same time, in order to increase the hand feeling, as shown in FIG. 4 and FIG. 5 , a plurality of rotating sliding teeth 91 distributed in an annular shape are formed on the inner wall of the rotating seat 9 , and at least one side movable groove 221 is formed on the positioning seat 2 , a spring 222 is arranged in the side movable slot 221 , and a sliding pin 223 abutting between the spring 222 and the rotating sliding tooth 91 is arranged in the side movable slot 221 . When the rotating base 9 is rotated 360°, the positioning base 2 is stationary, then under the action of the spring 222, the sliding tip 223 slides between the several rotating sliding teeth 91, and at the same time that the rotating rotating base 9 generates a signal, Also increases the feel.
