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 5, an embodiment of the present invention provides a rotary encoder switch, including a positioning seat 2 and a rotary seat 9 disposed on the positioning seat 2, wherein a contact spring 91 is disposed on the rotary seat 9; a PCB 10 is disposed on the positioning base 2, a conductive spring 101 electrically connected to the PCB 10 is disposed on the PCB 10, and the contact spring 91 is in contact with the conductive spring 101. When the rotary base 9 is rotated, the contact spring 91 is driven to slide on the conductive spring 101, so as to form an encoder capable of rotating 360 degrees and outputting a switch signal.

Specifically, as shown in fig. 6 and 7, the conductive elastic sheet 101 has three conductive terminals 1010 electrically connected to the PCB 10. Specifically, the conductive elastic sheet 101 is circular, and mainly comprises a third of the integral metal sheet 1011, a third of the discontinuous metal sheet a1012 and a third of the discontinuous metal sheet B1013, and the three conductive terminals 1010 are respectively a conductive terminal 10111 connected to the integral metal sheet 1011, a conductive terminal 10121 connected to the discontinuous metal sheet a1012 and a conductive terminal 10131 connected to the discontinuous metal sheet B1013. The intermittent metal sheet a1012 and the intermittent metal sheet B1013 are both intermittent toothed metal sheets, that is, a plurality of teeth (10120,10130) are respectively formed on the intermittent metal sheet a1012 and the intermittent metal sheet B1013, and a space (10122,10132) is formed between two adjacent teeth.

Meanwhile, the contact spring 91 is an annular spring, and the contact spring 91 has three contact pins 911 in sliding contact with the conductive spring 101.

When the contact spring 91 rotates along with the rotary base 9, the three contact pins 911 on the contact spring 91 respectively slide on the integral metal sheet 1011, the discontinuous metal sheet a1012 and the discontinuous metal sheet B1013, so as to realize discontinuous conduction and disconnection, form a pulse signal, and sense the clockwise rotation and the counterclockwise rotation of the encoder.

Specifically, as shown in fig. 6, when rotating clockwise, one of the contact pins 911 of the contact spring 91 slides on the integrated metal sheet 1011 to contact, the other contact pin 911 contacts with the teeth of the discontinuous metal sheet a1012, and the remaining contact pin 911 contacts with the empty space of the discontinuous metal sheet B1013. Therefore, during the continuous rotation, when each tooth position is rotated, the conductive terminal 10111 on the conductive elastic sheet 101 is connected to the conductive terminal 10121, or the conductive terminal 10111 is connected to the conductive terminal 10131. When the rotation is performed by one tooth, the conduction terminal 10111 and the conduction terminal 10121 are connected or the conduction terminal 10111 and the conduction terminal 10131 are switched to each other, and the pulse signal a is generated.

In the counterclockwise reverse rotation, similarly, each time the rotation is performed by one tooth, the conduction terminal 10111 and the conduction terminal 10121 are connected, or the conduction terminal 10111 and the conduction terminal 10131 are switched, so that the pulse signal B is generated.

Whether the rotation is clockwise or anticlockwise can be judged according to the front and back phases of the pulse signal A and the pulse signal B. When increment and decrement of a certain value are performed, for example, volume adjustment and audio adjustment are performed, and the increment/decrement of volume or audio is controlled by clockwise rotation and counterclockwise rotation.

By adopting the outer bearing 90 to connect the rotating seat 9 and the positioning seat 2, the rotating seat 9 can rotate 360 degrees relative to the positioning seat 2.

In this embodiment, a functional module 20 electrically connected to the PCB 10 is disposed at an upper end of the upper positioning cover 21 of the positioning base 2, and the functional module 20 may be a touch screen module 201, an OLED screen module or a key module 202, as shown in fig. 3 and 8.
