[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 6 It can be seen that an automatically reset electric control handle includes a base, which includes a base 1 and a support part 2. An arc-shaped groove is provided above the base 1, and the support part 2 is located inside the groove. A central axis 3 extends from one side of the support part 2, and a hand-feeling ring 4 extends from the other side of the support part 2. A left crank cover 5 and a right crank cover 6 are respectively provided on both sides of the support part 2. The left crank cover 5 and the right crank cover 6 rotate around the central axis 3. A PCB board 7 is provided inside the base, and a Hall sensor is provided on the PCB board 7. A magnetic steel 8 that cooperates with the Hall sensor is provided on the left crank cover 5. A first torsion spring 9 and a second torsion spring 10 are provided between the right crank cover 6 and the central axis 3. The first torsion spring 9 and the second torsion spring 10 are used to restore the left crank cover 5 and the right crank cover 6 to the middle position. A crank cap 11 is connected above the left crank cover 5 and the right crank cover 6, and a hand-feeling block 13 is connected to the bottom of the crank cap 11 via a spring 12. The hand-feeling block 13 slides outside the hand-feeling ring 4.

[0016] When the utility model is used in a specific way,

[0017] By controlling the crank cap 11 to drive the left crank cover 5 and the right crank cover 6 to rotate on the base, the magnet 8 is driven to rotate relative to the Hall sensor to generate magnetic flux, and then output a signal. After the force is released, the first torsion spring 9 and the second torsion spring 10 reset the left crank cover 5 and the right crank cover 6 to the middle position, completing an operation.

[0018] A feel block 13 is provided at the bottom of the crank cap 11 via a spring 12, which cooperates with the feel ring 4 in the base, so that the operating position can be sensed by hand, which is convenient for blind operation.

[0019] A convex point 14 and a locking point 15 are provided on the outside of the hand-feel ring 4. The convex point 14 is an arc-shaped structure with a diameter larger than that of the hand-feel ring 4. The locking point 15 is a stepped structure. The end of the hand-feel block 13 is a sharp-edged structure. When the hand-feel block 13 passes through the convex point 14, it will compress the spring 12. The change in the reaction force on the spring 12 can be fed back from the friction force during rotation. Therefore, the change in the rotation angle at this time can be sensed. When the hand-feel block 13 cooperates with the locking point 15, due to the stepped structure of the locking point 15, it can be locked with the hand-feel block 13, fixing the electric control handle at a certain angle, realizing continuous output of signals, and facilitating use in specific scenarios.

[0020] The first torsion spring 9 and the second torsion spring 10 are wound around the central axis 3, and a mounting plate 16 is arranged between the first torsion spring 9 and the second torsion spring 10. One end of the first torsion spring 9 and the second torsion spring 10 are connected to the mounting plate 16, and the mounting plate 16 can rotate around the central axis 3. The other end of the first torsion spring 9 hooks the right crank cover 6, and the other end of the second torsion spring 10 hooks the base 1. The first torsion spring 9 and the second torsion spring 10 reset the rotation of the left crank cover 5 and the right crank cover 6 in one direction respectively.

[0021] from Figure 4 It can be seen that when the left crank cover 5 and the right crank cover 6 are rotated counterclockwise, interference is generated between the lower end of the mounting plate 16 and the base and it cannot rotate, one end of the first torsion spring 9 is limited, and the other end of the first torsion spring 9 rotates with the right crank cover 6, and a reaction force is generated on the first torsion spring 9. After the fixing force applied to the left crank cover 5 and the right crank cover 6 is released, the reaction force can reset the left crank cover 5 and the right crank cover 6. Similarly, when the left crank cover 5 and the right crank cover 6 are rotated clockwise, one end of the second torsion spring 10 is limited by the base, and the other end of the second torsion spring 10 rotates with the mounting plate 16 to generate a reaction force, which is used to reset the left crank cover 5 and the right crank cover 6.

[0022] A connecting block 17 is provided at the bottom of the right crank cover 6, and the first torsion spring 9 hooks one side of the connecting block 17. When it rotates counterclockwise, it drives the first torsion spring 9 to rotate, and when it rotates clockwise, it pushes the mounting plate 16 to rotate, thereby rotating the second torsion spring 10, and then the first torsion spring 9 and the second torsion spring 10 complete the resetting of the electric control handle.

[0023] Compared with the prior art, the utility model has the following beneficial effects: compared with the traditional electric control handle, it is small in size and easy to install and use in specific scenarios; it uses contactless angle Hall sensing technology internally to achieve redundant signal transmission, high reliability and long service life; at the same time, a torsion spring is used between the crank cover and the base for reset, to achieve automatic return to the center position and simplify operation; a hand feeling block is provided to sense the change in the rotation angle of the handle, making operation convenient.
