[0059] In order to better understand the above technical solutions, the example embodiments of the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all embodiments of the present application. It should be understood that the present application is not limited to the example embodiments described herein.

[0060] In the existing operating assembly combining the knob and the button, the button element and the operating knob are usually arranged on the same side of the button circuit board, that is, the operating knob circumferentially surrounds the button seat. Since the button seat needs to be installed with the button, the button seat cannot provide extra radial space to install the elastic body, the ball, and other parts for damping feedback of the rotation of the operating knob. Thus, the operating knob has no feedback when rotating, thereby causing inconvenience in use.

[0061] In view of the above, the present application provides an operating assembly combining the knob and the button. Since the button element and the fixed support are arranged on the opposite surfaces of the button circuit board, the fixed support on the side opposite to the button element can provide a groove for bearing the elastic body, because the installation of the button does not need to be considered. In this way, the elastic body can provide damping feedback for the rotation of the operating knob by abutting against the gear ring of the operating knob through the ball.

[0062] Please combine Figures 1-4 An operating assembly combining the knob and the button, which comprises a button circuit board 10 perpendicular to a first direction X, a fixed support 20 fixedly installed with the button circuit board 10, and an operating knob 30 arranged in a hollow annular shape.

[0063] The button circuit board 10 comprises a first surface 11 and a second surface 12 opposite to each other, and the first surface 11 is provided with a button element 13 for being pressed and triggered. The fixed support 20 is fixedly installed on the second surface 12 of the button circuit board 10. The axial direction of the operating knob 30 is arranged along the first direction X, and the operating knob 30 circumferentially surrounds the button circuit board 10 and the fixed support 20 at least at the same time. The fixed support 20 is used for fixedly installing the operating assembly 30 on a device shell 100 of an electronic device, and allowing the operating knob 30 to freely rotate relative to the button circuit board 10 and the fixed support 20. The fixed support 20 is provided with a groove 21 extending along the radial direction of the operating knob 30, and the end of the groove 21 is arranged in an open manner. The groove 21 is used for bearing an elastic body 60. The operating knob 30 comprises a circumferential wall portion 31, which is provided with a gear ring 313 at a position corresponding to the groove 21 along the axial direction of the operating knob 30. The elastic body 60 elastically abuts against the gear ring 313 through a ball 70 to provide damping feedback for the rotation of the operating knob 30.

[0064] Overall, the embodiment provides damping feedback for the rotation of the operation knob by arranging the elastic body and the ball between the fixed support arranged on the back side of the key element and the operation knob, and by the elastic abutment of the ball and the operation knob.

[0065] Specifically, the first surface of the key circuit board is provided with a key element, which can be triggered when pressed in the first direction to provide a key operation function. The first direction is the vertical direction of the key circuit board.

[0066] The second surface of the key circuit board opposite to the first surface is fixedly installed with a fixed support. Then, the operation knob circumferentially surrounds the key circuit board and the fixed support. When the fixed support is fixedly installed in the device shell of the electronic device, the operation knob is freely rotatable.

[0067] Wherein, along the radial direction of the operation knob, the fixed support is provided with a groove with one end open, and the elastic body such as spring is carried in the groove. Along the axial direction of the operation knob (i.e. the first direction), the circumferential wall portion of the operation knob is provided with a gear ring at the position corresponding to the groove (the gear ring is arranged on the inner side of the circumferential wall portion). It can be understood that the gear ring includes a plurality of abutting teeth uniformly distributed. Then, the elastic body is elastically abutted with the gear ring through the ball, so that when the operation knob is rotated relative to the key circuit board and the fixed support, the elastic body is elastically abutted with the operation knob through the ball to provide damping feedback for the rotation of the operation knob.

[0068] It can be understood that by adjusting the protrusion height of the abutting teeth, the damping feedback can be adjusted, that is, the feedback feeling of the operation knob is adjusted, which is convenient to use.

[0069] In the embodiment, it can be seen that the fixed support on the side opposite to the key element does not need to consider the installation of the key matched with the key element (installation along the axial direction of the operation knob), so that the fixed support can conveniently provide space or groove along the radial direction of the operation knob to install the elastic body and the ball, which is simple and reasonable in structure.

[0070] The embodiment of the application provides an operation assembly combining a knob and a key and an electronic device. The operation assembly includes a key circuit board, a first surface of the key circuit board is provided with a key element for pressing and triggering, a second surface of the key circuit board opposite to the first surface is fixedly installed with a fixed support, and an operation knob circumferentially surrounds the key circuit board and the fixed support.

[0073] Regarding the installation of the operation knob 30, in one possible implementation, the operation knob 30 includes a tongue-pressing part 32 radially extending inward from the circumferential wall part 31 towards the end of the fixed support 20, and the tongue-pressing part 32 at least radially extends inward to the projection area of the fixed support 20, so that when the fixed support 20 is fixed to the equipment shell 100, the operation knob 30 is axially limited by the equipment shell 100 and the fixed support 20.

[0074] Regarding the above-mentioned installation of the free rotation of the operation knob, in the embodiment, referring to Figure 5 , the tongue-pressing part can be formed at the end of the circumferential wall part of the operation knob radially inward, wherein it can be understood that the tongue-pressing part should be located at the end of the circumferential wall part towards the fixed support, and the tongue-pressing part should at least radially extend inward to the projection area of the fixed support, so that when the fixed support is fixedly installed on the equipment shell, the embodiment can be limited by the equipment shell and the fixed support along the axial direction of the operation knob from both sides, that is, axially limited, thereby realizing the installation of the free rotation of the operation knob.
