[0039] Figure 1 is a schematic structural diagram of a key dialing device according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 5 The embodiment of the utility model provides a key-dial device, comprising a support seat 100, a key-dial 200 and an elastic support member 600, wherein the key-dial 200 is rotatably connected to the support seat 100 around a rotating shaft 250. The key-dial 200 comprises an extrusion block 210, and the two side surfaces of the extrusion block 210 are respectively a concave surface and a convex surface, so that the extrusion block 210 is curved. The elastic support member 600 is arranged on the support seat 100, and is located on the side of the extrusion block 210 close to the concave surface. The end of the elastic support member 600 facing the concave surface is provided with a slidable support head 611, and is configured to cause the support head 611 to slide toward the concave surface. The sliding direction of the support head 611 is perpendicular to the rotation axis of the key-dial 200, and a first groove 221 is provided on the concave surface. When the key-dial 200 rotates around the rotating shaft 250 by a first preset angle, the support head 611 slides into the first groove 221.

[0040] In this embodiment, after the dial key 200 is turned around the rotating shaft 250 by a first preset angle, the conductive structure is pressed so that the conductive structure contacts the circuit, thereby connecting the circuit to achieve control of the circuit state. In the process of turning the dial key 200, the support head 611 slides relative to the concave surface along the circumference of the rotating shaft 250 of the dial key 200, and the support head 611 is pressed by the concave surface or the groove wall of the first groove 221, and slides along the direction perpendicular to the rotation axis of the dial key 200 following the first groove 221 and the concave surface. When the dial key 200 is turned around the rotating shaft 250 by a first preset angle, the elastic support member 600 and the concave surface or the groove wall of the first groove 221 cause the support head 611 to collide with the first groove 221 to make a sound, and the user can get feedback of turning the dial key 200 from the sense of hearing, thereby improving the user's experience of turning the dial key 200. Moreover, due to the different resistances generated when the support head 611 is squeezed by the concave surface or the groove wall of the first groove 221, turning the key 200 will produce a sense of segmentation, and the user can get tactile feedback of turning the key 200, further improving the user's feeling of turning the key 200.

[0041] Preferably, the concave surface includes a section of a cylindrical surface, the cylindrical surface is coaxial with the rotating shaft 250, and the first groove 221 is arranged on the cylindrical surface.

[0042] In some embodiments of the key dialing device of the present invention, Figure 3 As shown, the concave surface is further provided with a second groove 222, and when the dial key 200 rotates around the rotating shaft 250 at a second preset angle, the support head 611 slides into the second groove 222. The first preset angle is set opposite to the second preset angle.

[0043] In this embodiment, the rotation of the dial key 200 at the first preset angle and the second preset angle can make the support head 611 enter the corresponding first groove 221 or second groove 222, so that the dial key device can control multiple circuits. The support head 611 collides with the first groove 221 or the second groove 222, so that the dial key device makes a sound and produces a sense of paragraph. When the user gets feedback from the hearing and touch of the dial key 200, the dial key 200 can squeeze the conductive structure to connect the corresponding circuit, so that the user can clearly perceive the success of the operation of the dial key 200, thereby improving the user's experience of dialing the dial key 200.

[0044] In some embodiments of the key dialing device of the present invention, Figure 3 As shown, the concave surface is also provided with a third groove 223 that cooperates with the support head 611. In the moving direction of the elastic support member 600 toward the dial key 200, the rotation axis of the dial key 200 and the third groove 223 are sequentially arranged. The first groove 221, the third groove 223 and the second groove 222 are sequentially arranged at intervals along the circumferential direction of the rotation axis of the dial key 200.

[0045] In this embodiment, the third groove 223 is disposed at the middle position of the concave surface, so that when the support head 611 is inserted into the third groove 223, the dial key 200 is in the reset state. In other words, when the dial key 200 is in the reset state, the third groove 223 plays a fixing role on the dial key 200, preventing the dial key 200 from being offset, causing the circuit state to be changed, and affecting the normal operation of the dial key device.

[0046] Preferably, the concave surface includes a cylindrical surface coaxial with the rotating shaft 250 , and the first groove 221 , the second groove 222 and the third groove 223 are all arranged on the cylindrical surface and are sequentially spaced in the circumferential direction of the rotating axis of the dial key 200 .

[0047] In some embodiments of the key-dial device of the present invention, the first groove 221 , the second groove 222 , and the third groove 223 are all grooves 220 with the same shape and size.

[0048] In some embodiments of the key dialing device of the present invention, Figure 3 As shown, a convex rib 224 formed by a concave surface protruding outward is arranged between the first groove 221 and the third groove 223 .

[0049] In this embodiment, the convex rib is located between the first groove 221 and the third groove 223. When the dial key 200 rotates around the rotating shaft 250 by a first preset angle, the support head 611 slides from the third groove 223 through the protrusion into the first groove 221. The protrusion squeezes the support head 611, causing the support head 611 to collide with the first groove 221. When the collision and contact occur, a sound is emitted. The user can get feedback of the dial key 200 being dialed from the sense of hearing, thereby improving the user's experience of dialing the dial key 200. Moreover, due to the different resistances generated in the process of the support head 611 being squeezed by the protrusion 224, the dial key 200 will produce a sense of segmentation. The user can get feedback of the dial key 200 being dialed from the sense of touch, thereby further improving the user's experience of dialing the dial key 200.

[0050] In addition, in some embodiments of the key-dial device of the present invention, a convex rib 224 formed by a concave surface protruding outward is provided between the third groove 223 and the second groove 222 .

[0051] In some embodiments of the key dialing device of the present invention, Figure 3 As shown, a convex rib 224 is formed on the concave surface of the first groove 221 away from the second groove 222 .

[0052] In this embodiment, the convex rib is located on a side of the first groove 221 away from the second groove 222 , and when the dial key 200 rotates around the rotation axis 250 at a first preset angle, it stops the support head 611 and prevents the dial key 200 from being turned too far.

[0053] In addition, in some embodiments of the key-dial device of the present invention, a concave surface of the second groove 222 on a side away from the first groove 221 protrudes outward to form a convex rib 224 .

[0054] In some embodiments of the key dialing device of the present invention, Figure 2 and Figure 3 As shown, the elastic support member 600 includes a push rod 610 and a reset device 620. The push rod 610 is movably mounted on the support seat 100 along its length direction, and the end of the push rod 610 facing the concave surface is provided with a support head 611. The reset device 620 causes the support head 611 to be inserted into the groove 220 through the push rod 610.

[0055] In this embodiment, during the process of turning the dial key 200, the support head 611 is squeezed by the groove wall of the groove 220, causing the push rod 610 to move along its length direction. The reset device 620 and the groove wall of the groove 220 cause the groove 220 to collide and contact with the support head 611, so as to produce a sense of paragraph and make a sound when the dial key 200 is turned, thereby improving the user's experience of turning the dial key 200.

[0056] Preferably, the reset device 620 is a compression spring.

[0057] In this embodiment, the compression spring is connected to the push rod 610, so that the support head 611 follows the rotation of the groove 220 and moves along the length direction of the push rod 610, so as to produce a sense of paragraph and a sound when the dial key 200 is turned. The compression spring has low cost, simple structure, and is easy to install, thereby reducing the production cost of the key device.

[0058] In some embodiments of the key dialing device of the present invention, Figure 2 As shown, the support seat 100 also includes a push rod support block 630 , which is disposed on the support seat 100 . A sliding hole 631 is disposed in the push rod support block 630 , and the push rod 610 and the reset device 620 are installed in the sliding hole 631 .

[0059] 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 .

[0060] In some embodiments of the key dialing device of the present invention, Figure 3 As shown, the tooth top angle α of the support head 611 is greater than 90° and less than 180°.

[0061] In this embodiment, when the tooth top angle α of the support head 611 is within the range of greater than 90° and less than 180°, the tooth top angle α of the support head 611 is smoother, making the impact sound between the support head 611 and the groove 220 softer, thereby improving the user experience.

[0062] Alternatively, the support head 611 is a ball head or a remaining structure after a part of the ball head structure is removed.

[0063] In this embodiment, the ball head has no tip, which avoids the tip from breaking due to collision and increases the service life of the support head 611.

[0064] In some embodiments of the key dialing device of the present invention, Figure 3 As shown, there is a gap H between the end of the support head 611 and the bottom of the groove 220 , and the height of the gap H is between 1 / 3 and 1 / 2 of the depth of the groove 220 .

[0065] In this embodiment, the height of the gap H is increased to reduce the depth of the support head 611 entering the groove 220. When the height of the gap H is between 1 / 3 and 1 / 2 of the depth of the groove 220, the groove 220 and the support head 611 make a sound when they collide, and a sense of segmentation is generated after the dial key 200 is dialed, and the user can get feedback that the dial key 200 is in place, which improves the user's experience of dialing the dial key 200. It also avoids the support head 611 from entering the groove 220 too much, thereby avoiding the need for greater force when dialing, and improving the user's experience.

[0066] In some embodiments of the key dialing device of the present invention, Figure 2 As shown, the key-dial device further includes a key 400. The support base 100 has a bottom frame 110, and a through hole 111 is provided on the bottom frame 110. The key 400 is arranged on one side of the bottom frame 110, and each key 400 is arranged corresponding to a through hole 111. The key 200 is arranged on the other side of the bottom frame 110. A pressure rod 800 is arranged between the key 200 and the key 400, and the pressure rod 800 passes through the through hole 111, and the pressure rod 800 transmits the pressing of the key 200 to the key 400.

[0067] In this embodiment, the dial key 200 is moved so that the pressure rod 800 squeezes the button 400 through the perforation 111, and the side of the button 400 close to the circuit can be provided with a conductive structure to connect the circuit. Alternatively, the button 400 can also be a conductive structure. The perforation 111 acts as a limit for the pressure rod 800 when it moves toward the circuit, preventing the pressure rod 800 from deviating when the dial key 200 causes the pressure rod 800 to move, and the circuit is not connected, causing the dial device to fail to work normally.

[0068] In some embodiments of the key dialing device of the present invention, Figure 1 As shown, the key-dial device further includes 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 200.

[0069] The key plate 520 may be a circuit board, or a circuit board may be provided on a side of the key plate 520 close to the dial key 200 .

[0070] 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.

[0071] 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.

[0072] 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.

[0073] In some embodiments of the key dialing device of the present invention, Figure 5 As shown, the key-dial device further includes a key base 410 , on which two keys 400 are disposed. The key base 410 and the two keys 400 are integrally formed, and the key base 410 and the two keys 400 are both made of rubber.

[0074] 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.

[0075] In some embodiments of the key dialing device of the present invention, Figure 1 or Figure 5 As shown, the dial key 200 further includes a dial block 240 and two end plates 230. The dial block 240 is disposed on the convex surface of the extrusion block 210. The two end plates 230 are respectively disposed at both ends of the extrusion block 210. The end plates 230 are rotatably mounted on the support seat 100 through a rotating shaft.

[0076] In this embodiment, the end plate 230 can be an integral structure with the rotating shaft. The design of the end plate 230 can improve the strength of the dial key 200, making it less likely to be damaged or broken. Moreover, the rotational connection between the end plate 230 and the support base 100 makes the connection between the dial key 200 and the support base 100 more secure, reducing the possibility of the dial key 200 falling off.

[0077] In some embodiments of the key dialing device of the present invention, Figure 4 As shown, the dial key device also includes a torsion spring 700. The torsion spring 700 includes a spring coil portion 710 and two arms 720 connected to the spring coil portion 710, and the spring coil portion 710 is sleeved on the rotating shaft. The two arms 720 are arranged on both sides of the spring coil portion 710, and each arm 720 has a first action position 731 and a second action position 732, and the first action position 731 is between the second action position 732 and the spring coil portion 710. The first action position 731 contacts the dial key 200, and the second action position 732 contacts the support seat 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 seat 100, so that when the dial key 200 is dialed to one side of the dial key 200, one of the two 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 prompting the dial key 200 to reset.

[0078] 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.

[0079] The embodiment of the utility model provides an air conditioner. In some embodiments of the air conditioner of the utility model, the air conditioner comprises the key dial device in any one of the above embodiments.

[0080] In this embodiment, after the dial key 200 is turned around the rotating shaft 250 by a first preset angle, the conductive structure is pressed so that the conductive structure contacts the circuit, thereby connecting the circuit to achieve control of the circuit state. In the process of turning the dial key 200, the support head 611 is pressed by the concave surface or the groove wall of the groove 220, and moves along the direction perpendicular to the rotation axis of the dial key 200 following the groove 220 and the concave surface. When the dial key 200 rotates around the rotating shaft 250 by the first preset angle or the second preset angle, the elastic support member 600 and the concave surface or the groove wall of the groove 220 cause the support head 611 to collide with the corresponding groove 220 to make a sound, and the user can get feedback of turning the dial key 200 from the sense of hearing, thereby improving the user's experience of turning the dial key 200. Moreover, due to the different resistances generated when the support head 611 is squeezed by the concave surface or the groove wall of the groove 220, turning the key 200 will produce a sense of segmentation, and the user can get tactile feedback of turning the key 200, further improving the user's feeling of turning the key 200.
