[0029] Please see Figures 1-5 As shown, the automatically resettable knob device provided in this application includes a knob 100, a torsion spring 110, and a fixing member 120.
[0030] The knob component 100 includes a first recessed groove 101 recessed on one side of the knob, and a first connecting post 102 and a first abutting member 103 are provided in the first recessed groove 101; the torsion spring 110 includes an assembly part and at least one connecting ear 111, the connecting ear 111 is connected to the assembly part, the assembly part is sleeved on the first connecting post 102, and the first abutting member 103 abuts against the connecting ear 111; the fixing member 120 is fastened to the knob component 100, and a second recessed groove 121 is recessed on the fixing member 120 facing the knob component 100, and a second connecting post 122 and a second abutting member 123 are provided in the second recessed groove 121, the second abutting member 123 abuts against the connecting ear 111, and the torsion spring 110 is also sleeved on the second connecting post 122.
[0031] By adopting the above technical solution, by rotating the knob 100, the first abutment 103 on the knob 100 rotates and pushes the connecting ear 111, and the second abutment 123 abuts against the torsion spring 110, so that the connecting ear 111 rotates and drives the torsion spring 110 to undergo elastic deformation, so that when the operator releases his hand, the torsion spring 110 is released and pushes the knob 100 to reset.
[0032] In one specific implementation, the automatically resetting knob device further includes a connecting rod 130, which passes through the knob 100 and the fixing member 120. A through hole is provided on the first connecting post 102 and the second connecting post 122, and the connecting rod 130 is located within the through hole. The connecting rod 130 is also fixedly connected to the knob 100. Rotation of the knob 100 drives the connecting rod 130 to rotate. A threaded hole is provided at the end of the connecting rod 130 facing the knob 100, and a screw 131 is also provided at the through hole on the first connecting post 102. The knob 100 is fixedly connected to the connecting rod 130 by the screw 131. The automatically resetting knob device also includes a circuit board 140, on which a sensor 141 is provided. The sensor 141 is rotatably connected to the connecting rod 130, causing the connecting rod 130 to rotate.
[0033] By adopting the above technical solution, when the knob 100 rotates, it drives the connecting rod 130 to rotate. The connecting rod 130 is connected to the transmission device. When the connecting rod 130 rotates, it changes the voltage and resistance of the sensor 141.
[0034] In one specific implementation, the fastener 120 is fixedly connected to the circuit board 140 by screws 131. Alternatively, it can be fixedly connected by other methods such as plugging or soldering.
[0035] In one specific embodiment, the torsion spring 110 includes two connecting ears 111, which abut against both ends of the first abutment member 103 and both ends of the second abutment member 123, respectively. The first abutment member 103 has an arc-shaped plate structure, with at least one end abutting against the connecting ear 111; the second abutment member 123 has an arc-shaped plate structure, with at least one end abutting against the connecting ear 111. The second abutment member 123 is used to restrict the torsion spring 110 from rotating. The connecting ears 111 have a rectangular structure to increase the contact area between the connecting ears 111 and the first abutment member 103 and the second abutment member 123.
[0036] In one specific implementation, a fastening plate 150 is connected to the side of the knob 100 away from the fixing member 120. The fastening plate 150 is provided with a fastening member 151, and the knob 100 has a fastening groove 152 corresponding to the fastening member 151 on the side facing the fastening plate 150. The fastening plate 150 can be used to hide the screw 131 used for assembling the connecting rod, improving the appearance.
[0037] In one specific implementation, a limiting member 124 is also provided in the second settling tank 121, and the limiting member 124 is arranged opposite to the second abutment member 123 at a distance. The limiting member 124 is used to limit the range of rotation of the knob member 100.
[0038] In summary, rotating the knob 100 causes the connecting rod to rotate, which in turn changes the resistance and voltage of the sensor 141. Furthermore, the rotation of the knob 100 causes the torsion spring 110 to deform elastically. Upon release, the torsion spring 110 pushes the knob 100 back to its original position, thus achieving automatic reset. The overall structure is simple, and the torsion spring 110 is easy to replace and maintain, improving the overall service life.
[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
