[0032] The switch assembly 1 can open or close the circuit by adjusting the state, thereby realizing the on-off control of the current and controlling the closing or opening of the switch. The regulating assembly 2 adjusts the passage or disconnection state of the switch device by movement. The movement of the regulating assembly 2 can cause the state of the switch assembly 1 to change, thereby affecting the conduction or disconnection of the circuit.

[0039] In one implementation, the elastic member 3 is any one of a torsion spring, a bending spring, and a spring sheet.

[0040] The elastic member 3 generates elastic force through deformation. The elastic force generated by the elastic member 3 is determined by the material properties of the elastic member 3, the geometric shape of the elastic member 3 and the deformation of the elastic member 3. The magnitude and direction of the elastic force and the input force can amplify or reduce the force ultimately acting on the switch assembly 1.

[0041] Optionally, the elastic member 3 is a torsion spring. Torsion springs have advantages over ordinary springs. The spiral design enables the torsion spring to provide greater elasticity in a limited space and has higher space efficiency. The torsion spring stores and releases energy through twisting stretching or compression rather than lateral or longitudinal stretching or compression. Therefore, it is more suitable for applications that require rotation and can provide a wide range of rotational motion. Due to the particularity of the design structure, the deformation of the torsion spring after being subjected to force is relatively uniform, showing strong stability, and is suitable for long-term use scenarios. The wire diameter of the torsion spring, the number of turns of the torsion spring, and the expansion angle of the torsion spring will change the force of the torsion spring to meet the design requirements.

[0042] Optionally, the elastic member 3 is a bending spring. The bending spring has elastic deformation characteristics and can undergo elastic deformation after being subjected to force. When an external force acts on the bending spring, the bending spring undergoes elastic deformation, stores energy, and quickly returns to its original shape, generating an adjusted force output. By adjusting the material, shape or size of the bending spring, different elasticities and forces can be achieved to meet the needs of different applications. The simple structure and reliability of the bending spring make it easy to use in various mechanical systems. Since its elastic force can be precisely controlled by adjusting the material, shape or size, the bending spring becomes a highly customizable component suitable for different engineering needs. At the same time, due to the durability of materials such as metals, the bending spring usually has high reliability and can maintain stable performance during long-term use.

[0043] Optionally, the elastic member 3 is a spring. The spring has good elasticity and elastic deformation after being subjected to force, and can adjust the force received and output an adjusted force. At the same time, the spring can protect the equipment, reduce vibration, and improve the performance and stability of the system. The lightweight design and customizability of the spring make it adaptable to various design requirements.

[0044] In one embodiment, the switch device includes a central shaft 11, an adjustment component 2 is rotatably connected to the central shaft 11, and an elastic member 3 is sleeved on the central shaft 11; the axis of the central shaft 11 is a rotation center 11A; when the adjustment component 2 rotates, the elastic member 3 is compressed or extended, and the compression or extension of the elastic member 3 drives the switch component 1 to move.

[0045] The adjustment component 2 is rotationally connected to the central shaft 11. When the rotation occurs, the central shaft 11 is stationary, and the adjustment component 2 rotates relative to the central shaft 11. The rotation can be clockwise or counterclockwise. The sleeve between the elastic member 3 and the central shaft 11 can be an inserted sleeve, a sliding sleeve, a pressed sleeve, and a snap-fit ​​sleeve. The rotational connection between the adjustment component 2 and the central shaft 11 and the sleeve of the elastic member 3 on the central shaft 11 enable the three to work together. The rotation on the adjustment component 2 is transmitted to the elastic member 3, driving the elastic member 3 to compress or stretch. The central shaft 11 can also fix the relative position of the adjustment component 2 and the elastic member 3 to ensure that the switch device remains stable and reliable during movement.

[0046] When adjusting component 2 is rotated clockwise, please refer to Figure 2 , a part of the adjusting component 2 is acted upon by the external force rotating clockwise, driving the adjusting component 2 to rotate clockwise. A part of the adjusting component 2 drives a part of the elastic member 3 to compress and generate elastic force, and the adjusted elastic force drives the switch component 1 to move; when the adjusting component 2 rotates counterclockwise, a part of the adjusting component 2 is acted upon by the external force rotating counterclockwise, driving the adjusting component 2 to rotate counterclockwise. A part of the adjusting component 2 drives a part of the elastic member 3 to compress and generate elastic force, and the adjusted elastic force drives the switch component 1 to move.

[0047] In one embodiment, the switch assembly 1, the adjustment assembly 2, the elastic member 3 and the central axis 11 satisfy the relationship:

[0048]

[0049] Among them, F1 is the force on the switch component 1; F2 is the force on the adjustment component 2; L1 is the distance from F1 to the rotation center 11A; L2 is the distance from F2 to the rotation center 11A; M3 is the torque generated by the elastic member 3.

[0050] The force F1 on the switch assembly 1 is affected by the force F2 on the adjustment assembly 2, the distance L2 from the force F2 on the adjustment assembly 2 to the rotation center 11A, the torque M3 generated by the elastic member 3, and the distance L1 from the force F1 on the switch assembly 1 to the rotation center 11A. This relationship is essentially a force and torque balance equation. It indicates that the force F1 on the switch assembly 1 is equal to the combined effect of the force F2 on the adjustment assembly 2 and the torque M3 generated by the elastic member 3 at the rotation center 11A. This balance relationship can control the switch device to be stable and controllable during movement and adjustment. F2, L2, M3, and L1 are adjusted to adjust F1 so that F1 can meet the requirements of the switch assembly 1.

[0051] Please refer to Figure 3 , Figure 3The adjusting component 2 is subjected to the clockwise force F2, L2 is the distance from the contact point on the adjusting component 2 subjected to F2 (the starting point of the arrow F2) to the rotation center 11A, M3 is the torque generated by the elastic member 3, F1 is the force on the switch component 1, and L1 is the distance from the contact point on the switch component 1 subjected to F1 (the starting point of the arrow F1) to the rotation center 11A. In one embodiment, the adjusting component 2 includes an input member 21 and a lever bracket 22; the input member 21 is connected to the lever bracket 22; and the lever bracket 22 is connected to the elastic member 3.

[0052] The input member 21 can be a button, a knob and a lever. Optionally, the input member 21 is a lever, which can be adjusted continuously and gradually within a range; the shape and operation mode of the lever are more ergonomic, easier to understand and operate, and can be easily adjusted and controlled. The connection between the input member 21 and the lever bracket 22 can be a pin connection, a sleeve connection, a clamping bayonet design and welding. The input member 21 is subjected to external forces and can input force into the switch device. The input member 21 is connected to the lever bracket 22 to transfer the force on the input member 21 to the lever bracket 22. After receiving the force, the lever bracket 22 rotates clockwise or counterclockwise to contact the elastic member 3, and then drives the elastic member 3 to compress or stretch.

[0053] In one implementation, please refer to Figure 1 The lever bracket 22 includes a third end 22A and a fourth end 22B that are disposed opposite to each other, and the third end 22A and the fourth end 22B are disposed opposite to each other in the radial direction of the central axis 11. The switch assembly 1 includes a first button group 12 and a second button group 13; the lever bracket 22 rotates so that the third end 22A squeezes the first button group 12, or so that the fourth end 22B squeezes the second button group 13.

[0054] In the radial direction of the central axis 11, the lever bracket 22 includes a third end 22A and a fourth end 22B, and the third end 22A and the fourth end 22B are arranged opposite to each other relative to the central axis 11. The opposite arrangement of the third end 22A and the fourth end 22B allows the lever bracket 22 to be controlled in two directions. The lever bracket 22 can be rotated clockwise or counterclockwise in the radial direction of the central axis 11 by operating the input member 21, so that the elastic member 3 can generate opposite forces or torques in two directions at the same time, thereby realizing two-way control. The switch assembly 1 has two groups of button groups. The first button group 12 and the second button group 13 of the switch assembly 1 respectively control the two states of the switch device. The first button group 12 and the second button group 13 can be used to perform different functions or operations respectively to meet different usage scenarios and needs. When the lever bracket 22 rotates clockwise, part of the elastic member 3 is compressed, and another part of the elastic member 3 is stretched, driving the third end 22A to squeeze the first button group 12; when the lever bracket 22 rotates counterclockwise, part of the elastic member 3 is compressed, and another part of the elastic member 3 is stretched, driving the third end 22A to squeeze the second button group 13.

[0055] In one embodiment, the elastic member 3 includes a first end 3A and a second end 3B that are disposed opposite to each other, and the first end 3A and the second end 3B are disposed opposite to each other in the radial direction of the central axis 11 .

[0056] The elastic member is provided with a first end 3A and a second end 3B opposite to each other, and can generate a relative torque in the radial direction of the central axis 11. When an external force or torque is applied, the first end 3A of the elastic member 3 will be compressed, and the second end 3B will be stretched, or the first end 3A of the elastic member 3 will be stretched, and the second end 3B will be compressed. The elastic member 3 can be twisted in two directions, thereby pressing the first button group 12 or the second button group 13, and driving the first button group 12 or the second button group 13 to move.

[0057] In one embodiment, the first button group 12 includes a first button bracket 121, a first deformable member 122 and a first electrical signal line 123; the second button group 13 includes a second button bracket 131, a second deformable member 132 and a second electrical signal line 133; the lever bracket 22 rotates so that the first button bracket 121 squeezes the first deformable member 122 to conduct the first electrical signal line 123, or so that the second button bracket 131 squeezes the second deformable member 132 to conduct the second electrical signal line 133.

[0058] The first key bracket 121 is a supporting structure of the first key group 12, connecting the elastic member 3 and the first deformable member 122; the second key bracket 131 is a supporting structure of the second key group 13, connecting the elastic member 3 and the second deformable member 132. The first deformable member 122 and the second deformable member 132 can be rubber, elastic plastic and elastic polymer. The opening or shorting of the first electrical signal line 123 and the second electrical signal line 133 can control the opening or closing state of the switch device.

[0059] Please refer to Figure 1 When the input member 21 rotates clockwise, the lever bracket 22 rotates clockwise relative to the rotation center 11A of the central axis 11, the third end 22A rises away from the first end 3A, the third end 22A is pressed down close to the second end 3B, the elastic member 3 is stretched near the first end 3A, and the elastic member 3 is compressed near the second end 3B. The elastic member 3 deforms to generate elastic force, and the force adjusted by the elastic force on the elastic member 3 drives the second button group 13 to move, and the second button bracket 131 squeezes the second deformable member 132 to conduct the second electrical signal line 133. When the input member 21 rotates counterclockwise, the lever bracket 22 rotates counterclockwise relative to the rotation center 11A of the central axis 11, the third end 22A is pressed down close to the first end 3A, and the third end 22A rises away from the second end 3B, the elastic member 3 is compressed near the first end 3A, and the elastic member 3 is stretched near the second end 3B.
