[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-6As shown, a stepless speed regulating retarder switch comprises a lever 1, a housing 2, and a rotating block 3 arranged in the housing 2 and linked to the lever 1. A containing space 21 is arranged in the seat body, and the rotating block 3 can be rotatably arranged in the containing space 21. A positioning groove 31 is arranged at the bottom of the rotating block 3, and a magnet 32 ​​is fixed in the positioning groove 31. A Hall circuit board 4 corresponding to the magnet 32 ​​is arranged below the rotating block 3; an outer edge of the rotating block 3 is configured as an arc surface 33, and a corresponding arc surface 33 is arranged in the housing 2. The arc-shaped mating surface 22 is provided with at least one limiting groove 23, and an elastic column 34 extending out of the arc-shaped surface 33 and cooperating with the limiting groove 23 is installed in the rotating block 3; the two side portions of the rotating block 3 are configured as inclined surfaces 35, and abutment surfaces 24 that can abut and cooperate with the inclined surfaces 35 are provided at both sides of the shell 2 facing the arc-shaped mating surface 22; at least one end of the upper and lower ends of the rotating block 3 is provided with a shaft 36 that rotates with the shell 2; the Hall circuit board 4 is installed at the bottom of the shell 2.

[0022] By adopting the above technical solution, in the present invention, the main innovation of the present invention is to set a magnet 32 ​​on the rotating block 3 and to set a Hall sensor at a position corresponding to the magnet 32 ​​below the rotating block 3. When the driver turns the lever 1, the rotating block 3 rotates, and the rotation angle corresponds to the analog signal. In this way, the driver's operation is converted into a continuous electrical signal, thereby realizing stepless speed regulation of the retarder.

[0023] The combination of the elastic bead and the limiting groove 23 can increase the operating feel and limit the rotation angle of the rotating block 3. One or more limiting grooves 23 can be provided according to actual use. The combination of the inclined surface 35 and the abutting surface 24 can limit the maximum rotation angle of the rotating block 3. The combination of the arc-shaped matching surface 22 and the arc-shaped surface 33 increases the rotation adjustment range of the rotating block 3 compared with the straight surface setting.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
