[0028] Example 1

[0029] Reference Figure 1-9 A push-type knob includes a knob base 1, the interior of the knob base 1 is a hollow accommodating cavity 12, a circuit board 5 that moves up and down is arranged in the accommodating cavity 12, a push switch 6 is installed at the bottom of the circuit board 5, and a number of elastic parts are arranged between the circuit board 5 and the inner bottom of the accommodating cavity 12. A knob hole 14 leading to the accommodating cavity 12 is opened on the upper surface of the knob base 1, and a knob 2 that can rotate and move up and down is arranged in the knob hole 14. An upward hollow slot is opened at the bottom of the knob 2, and an inner gear ring 23 is arranged in the hollow slot. An encoder 52 is installed on the circuit board 5, and a gear 53 that cooperates with the inner gear ring is installed on the rotating shaft of the encoder 52.

[0030] Preferably, a toothed ring 31 is fixedly provided on the outer circumferential surface of the knob 2, and a circle of wavy grooves 33 are provided on the upper surface of the toothed ring 31. A V-shaped elastic tooth 32 that cooperates with the groove 33 is fixed on the inner top surface of the accommodating cavity 12, and the tip of the V-shaped elastic tooth 32 is an arc-shaped end 34.

[0031] Preferably, the knob base 1 includes a lower base 11, the upper surface of the lower base 11 is a concave accommodating cavity 12, a base panel 13 is fixed to the upper surface of the lower base 11, the knob hole 14 is opened on the base panel 13, and the V-shaped elastic tooth 32 is fixed on the lower bottom surface of the base panel 13.

[0032] Preferably, a plurality of screw hole columns 15 are fixed on the lower base 11 , and a plurality of screw holes corresponding to the screw hole columns 15 are opened on the base panel 13 . The lower base 11 and the base panel 13 are fixedly connected by screws 151 .

[0033] Preferably, the elastic member is a spring 17, and a plurality of limiting columns 16 are fixed to the inner bottom of the lower base 11. The spring 17 is sleeved outside the limiting column 16. A limiting column hole 51 corresponding to the limiting column 16 is opened on the circuit board 5. The diameter of the limiting column hole 51 is smaller than the diameter of the spring 17, and the limiting column 16 is sleeved in the limiting column hole 51.

[0034] Preferably, a plurality of elastic sheet slots 18 are opened on the side of the lower base 11, and an elastic sheet 19 is fixed in the elastic sheet slot 18.

In this way, the user can not only feel more accurate positioning feedback, but also enjoy a richer and more satisfying control experience and interactive feeling. When pressing, directly press the knob 2 downward, the knob 2 drives the circuit board 5 to overcome the elastic force of the spring 17 and move downward, so that the press switch 6 contacts the bottom of the lower base 11 to achieve pressing. After releasing the knob 2, the knob 2 is reset under the elastic force of the spring 17.

[0038] The utility model has a simple structure, simple production, low cost, and also has flexible two-way rotation and pressing operation functions. While ensuring product performance, it greatly reduces manufacturing costs and structural complexity, reflecting higher economy and practicality.

[0040] This embodiment differs from the first embodiment in that, instead of using the toothed ring 31 and the V-shaped elastic teeth 32, a limiting device for limiting the upper position of the knob is provided on the outer circumference of the knob 2. The limiting device is a limiting ring, which is sleeved on the outer circumference of the knob and located below the knob hole. The limiting ring is used to limit the upper position of the knob 2 and prevent the knob 2 from falling out of the knob hole 14.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
