Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments.

Referring to fig. 1 to 3, an embodiment of the present invention provides a photoelectric driving rotary switch, including a positioning seat 2 and a rotary seat 9 disposed on the positioning seat 2, wherein a plurality of stoppers 92 are annularly distributed in the rotary seat 9; a PCB 10 is disposed on the positioning base 2, and a plurality of photoelectric switches 101 corresponding to the stoppers 92 are disposed on the PCB 10. Specifically, the optoelectronic switch 101 may be a U-shaped transmissive optoelectronic switch or a reflective optoelectronic switch.

When the rotary base 9 is rotated, the photoelectric switch 101 and the plurality of stoppers 92 in the rotary base 9 generate information sources. Specifically, when the rotary base 9 is rotated, the plurality of stoppers 92 in the rotary base 9 rotate, and the photoelectric switch 101 is also stationary since the positioning base 2 is stationary. Therefore, when the rotary base 9 rotates to a position where one of the stoppers 92 is located between the photoelectric switches 101, the light of the photoelectric switches 101 is blocked by the stoppers 92, and a signal is output to the PCB 10; when the rotary base 9 rotates to a position where no stopper 92 is located between the photoelectric switches 101, that is, the photoelectric switches 101 are located between two adjacent stoppers 92, and the light of the photoelectric switches 101 is not blocked, another signal is output to the PCB board 10.

Therefore, when the rotary base 9 is rotated by 360 °, the electro-optical switch 101 and the plurality of stoppers 92 in the rotary base 9 generate different signals and signal the PCB board 10, so that different functions, such as volume adjustment, menu selection, etc., can be defined.

Meanwhile, in order to increase the hand feeling, as shown in fig. 4 and 5, a plurality of rotating sliding teeth 91 are formed on the inner wall of the rotating base 9 and distributed annularly, at least one side moving groove 221 is formed on the positioning base 2, a spring 222 is arranged in the side moving groove 221, and a sliding pin 223 abutting between the spring 222 and the rotating sliding teeth 91 is arranged in the side moving groove 221. When the rotating base 9 rotates by 360 degrees, the positioning base 2 is still, and under the action of the spring 222, the sliding pin 223 slides among the plurality of rotating sliding teeth 91, so that the hand feeling is increased while the rotating base 9 generates signals.

As for the specific structure of the positioning base 2, as shown in fig. 5, the positioning base 2 mainly comprises an upper positioning cover 21 and a central positioning rod 22 disposed in the middle of the lower end of the upper positioning cover 21, wherein the rotating base 9 is disposed at the lower portion of the upper positioning cover 21 and located at the periphery of the central positioning rod 22, and the PCB 10 is disposed on the upper positioning cover 21, as shown in fig. 3 and 4.
