At least one collision groove 221 is arranged on each side of the positioning groove 222, and the collision groove 221 and the positioning groove 222 are arranged in sequence and spaced apart along the circumferential direction of the rotation axis of the dial key 200.

[0057] Alternatively, in some alternative embodiments of the key-dial device of the present invention, the collision groove 221 is disposed on both sides of the middle position of the concave surface.

[0058] In some embodiments of the key-dial device of the present invention, the support head 611 is a ball head or a remaining structure after a part of the ball head is removed.

[0059] In this embodiment, the top of the support head 611 is flat, so that the impact sound of the support head 611 and the collision groove 221 or the positioning groove 222 is softer, which improves the user's experience. In addition, the ball head has no tip, which avoids the tip from breaking due to collision and improves the service life of the support head 611.

[0060] In some embodiments of the dial key device of the present invention, the support head 611 is a support column parallel to the rotation axis of the dial key 200 , and the cross section of the support column is circular, arched, or fan-shaped.

[0061] In this embodiment, the contact area between the support column and the collision groove 221 or the positioning groove 222 is larger, so that the impact sound between the support head 611 and the collision groove 221 or the positioning groove 222 is softer, thereby improving the user's experience.

[0062] In some embodiments of the key-dial device of the present invention, the reset device 620 is a compression spring.

[0063] In this embodiment, by connecting the compression spring to the push rod 610, the support head 611 follows the rotation of the collision groove 221 or the positioning groove 222 and moves along the length direction of the push rod 610, so as to produce a sense of segmentation when the dial key 200 is dialed, thereby improving the user's dialing experience. The compression spring has low cost, simple structure, and is easy to install, thereby reducing the production cost of the key dial device.

[0064] In some embodiments of the key-shifting device of the present invention, the support seat 100 also includes a push rod support block 630, which is arranged on the bottom frame 110, and a sliding hole 631 is arranged in the push rod support block 630, and the push rod 610 and the reset device 620 are installed in the sliding hole 631.

[0065] In this embodiment, the sliding hole 631 serves to limit the push rod 610 when it moves along its length direction, thereby preventing the push rod 610 from deviating when it moves, thereby affecting the normal movement of the dial key 200 .

[0066] In some embodiments of the key dialing device of the present invention, the key dialing device further comprises a key box 510 and a key plate 520, wherein the key plate 520 is disposed in the key box 510, and the support base 100 is mounted on the key box 510 or the key plate 520. The key 400 is disposed between the key plate 520 and the support base 100 to press the key plate 520 after receiving the pressing of the key dialing key 200.

[0067] In this embodiment, the key box 510 protects the key 400, preventing the key 400 from being damaged due to collision. In addition, the design of the key box 510 makes the arrangement of other components in the key dialing device more neat, making the key dialing device more beautiful.

[0068] In some embodiments of the key dialing device of the present invention, the key 400 is an elastic key 400 with a self-resetting function.

[0069] In this embodiment, the elastic key 400 can automatically reset to the shape before being pressed, thereby avoiding long-term compression of the circuit board, so that the circuit state can be quickly changed by turning the key 200.

[0070] In some embodiments of the key-dial device of the present invention, the key-dial device further includes a key seat 410 , on which two keys 400 are disposed. The key seat 410 and the two keys 400 are integrally formed, and the key seat 410 and the two keys 400 are both made of rubber.

[0071] In this embodiment, the key base 410 and the two keys 400 are integrally formed, so that the keys 400 are more firmly fixed, and the keys 400 are prevented from sliding, thereby preventing the keys 400 from being squeezed due to the displacement of the keys 400, and reducing the failure rate of the key-push device. The rubber material has low cost, good elasticity, and self-reset capability.

[0072] In some embodiments of the key dialing device of the present invention, Figure 3As shown, the dial key device further includes a torsion spring 700, which is arranged between the dial key 200 and the support seat 100 to cause the dial key 200 to reset. The torsion spring 700 includes a spring coil portion 710 and two support arms 720 connected to the spring coil portion 710, and the spring coil portion 710 is sleeved on the rotating shaft 250.

The first action position 731 contacts or is connected to the dial key 200, and the second action position 732 contacts or is connected to the support seat 100, so that when the dial key 200 is dialed to one side of the dial key 200, one of the two support arms 720 acts on the support seat 100, and the other acts on the dial key 200, so that the torsion spring 700 accumulates force, thereby causing the dial key 200 to reset.

[0073] Preferably, in some embodiments of the dial key device of the present invention, the first action position 731 contacts the dial key 200, and the second action position 732 contacts the support base 100. The two first action positions 731 and the two second action positions 732 are located on the same side of the corresponding contact positions on the dial key 200 and the support base 100.

[0074] In this embodiment, when the dial key 200 is moved sideways, the torsion spring 700 generates a force to urge the dial key 200 to reset, so that the dial key 200 automatically resets, reducing the user's operation and improving the user's experience. The structure of supporting the torsion spring 700 by the support base 100 and using the torsion spring 700 to store force to support the dial key 200 to reset is simple, easy to manufacture and install, and reduces production costs.

[0077] The dial key 200 itself is provided with a pressing block 210, which moves or rotates with the dial key 200. When the dial key 200 is turned, the pressing block 210 directly presses the key 400 through the through hole 111. A conductive structure may be provided on one side of the key 400 close to the circuit to connect the circuit. Alternatively, the key 400 may also be a conductive structure.

[0078] In this embodiment, the state of the circuit can be controlled by moving the dial key 200 to a specified position. The dial key 200 can directly contact the button 400 through the extrusion block 210, and no other components are required, thereby reducing the number of components. During installation, the dial key 200 only needs to be installed on the bottom frame 110, and no other components need to be installed, so that the dial key 200 can squeeze the button 400 to connect the circuit, thereby reducing the difficulty of installing the dial key device and reducing the production cost of the dial key device.
