Description

Technical Field

[0001] This invention relates to a motor commutation speed control design, specifically a bidirectional reset speed control throttle. Background Technology

[0002] Speed ​​control throttles can convert the rotation angle of the throttle into a continuously changing voltage value through Hall effect sensors, thereby controlling the motor speed. Most existing speed control throttles can only control the motor's forward rotation. When switching between forward and reverse rotation is needed, it's often done via a button. While this design is user-friendly and safe in the electric vehicle industry, it's cumbersome in rail transport motor control or elevators. A direct forward / reverse speed control throttle that controls the motor's forward and reverse rotation and corresponding speed would be much easier to operate. Summary of the Invention

[0003] In view of the problems mentioned in the background art, the purpose of this invention is to provide a bidirectional reset speed control throttle, which can control the forward and reverse rotation of the motor accordingly when the handle is turned forward or reversed.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a bidirectional reset speed regulating throttle, including a controller and a motor, and further including a base and a rotating handle. The rotating handle is mounted on the base and rotates with the base. A sensing component is provided on one side of the base. The sensing component includes a sensing base, which is mounted on the base. A sensor insert is mounted on the sensing base. Hall sensor one and Hall sensor two are respectively provided on both sides of the sensor insert. The end of the rotating handle is located inside the sensing base. Arc magnet one and arc magnet two are respectively installed on the upper and lower sides of the end of the rotating handle. The arc magnet one, arc magnet two, Hall sensor one, and Hall sensor two are evenly distributed around the rotating handle. Hall sensor one and Hall sensor two are both connected to the controller.

[0005] Preferably, the other side of the base is provided with a bidirectional rotational reset assembly, which includes a slide block mounted on the base. One end of a spring abuts against the slide block, and the other end abuts against the slider. Both the spring and the slider are located inside the slide block, and the slider slides in cooperation with the slide block. The end of the rotating handle is located inside the slide block, and a cam is sleeved on the end of the rotating handle. The cam can abut against the slider.

[0006] Preferably, the sensor insert is detachably connected to the sensing base.

[0007] Preferably, a bearing is installed at one end of the rotating handle, and the rotating handle is rotatably engaged with the induction base through the bearing.

[0008] Preferably, a second bearing is mounted on the cam, and the rotating handle is rotatably engaged with the slide block via the cam and the second bearing.

[0009] Preferably, a cover plate is also included, which is detachably connected to the sensing base through a rotating handle.

[0010] Preferably, a second cover plate is also included, which is detachably connected to the slide through the rotating handle.

[0011] In summary, the present invention has the following advantages: the speed control throttle of the present invention can control the speed and direction of the motor by rotating the handle clockwise and counterclockwise, and can also control the start and stop of the motor by rotating the handle to automatically reset. The control logic is intuitive and easy to use. Attached Figure Description
