[0026] Embodiments of the present application are described in detail below with reference to the accompanying drawings, wherein the same or similar notations used throughout the drawings and the specification denote the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application. In the description of the present application, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and therefore should not be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be understood as limiting the present application.

[0027] Please refer to Figures 1-9 , the present application provides an embodiment: a handle type speed regulator, comprising a base 1, one side of the base 1 is provided with a handle 8, and the handle 8 is used to drive a linkage 4 provided in the base 1 to rotate, and the linkage 4 is provided with a driving tooth 5; the other side of the base 1 is movably connected with a detection assembly 3 provided thereon, the detection assembly 3 comprises a housing 30, one side of the housing 30 is further provided with a driven wheel 34 engaged with the driving tooth 5, and the driven wheel 34 is further provided with a trigger 32; the other side of the housing 30 is further provided with a circuit board 31, and the position of the trigger 32 is obtained through the circuit board 31.

[0028] In summary, since the device utilizes the engagement of the driving tooth 5 and the driven wheel 34, the power of the handle 8 can be transmitted to the driven wheel 34 through the gear transmission, and the rotation of the trigger 32 is driven by the driven wheel 34. When the trigger 32 rotates, it can trigger the detection module on the circuit board 31, and then output the detected signal to the control device through the circuit board 31, thereby improving the transmission accuracy of the device, and the device can accurately obtain signals even on bumpy roads. The circuit board 31 is an integrated component, that is, the circuit board 31 is provided with a detection module for identifying the rotation angle of the trigger 32; and the rotation angle of the trigger 32 is identified in real time through the detection module, and the angle signal is converted into an analog signal output.

[0029] Especially, since the detection assembly 3 is movably installed in the base 1, specifically, the shell 30 is fixedly installed in the mounting cavity 15 provided on the base 1. Thus, the detection assembly 3 can be replaced, and the speed regulator can be replaced by replacing different detection assemblies to realize the replacement of the speed regulator function. For example, the replaceable functional components include but are not limited to linear Hall brackets, normally open switches, gear adjustment assemblies (such as Figure 9 As shown, that is, the entire circumferential surface of the linkage 4 is provided with teeth); after replacing the corresponding components, at least one of the linear Hall signal output, the multifunctional switch control, and the gear adjustment signal output can be realized.

[0030] Further, since the side of the linkage 4 facing the handle 8 is also provided with a tooth groove 11, and the handle 8 is connected to the tooth groove 11 through the tooth pin 7 provided thereon. Therefore, the power of the handle 8 can be reliably transmitted to the linkage 4, and the phenomenon of slipping between the handle 8 and the linkage 4 can also be effectively avoided; wherein the number of tooth pins 7 and tooth grooves 11 is equal, preferably three, wherein the tooth pins 7 are equidistantly distributed on the outer end surface of the handle 8, and the tooth grooves 11 are equidistantly distributed on the inner wall surface of the linkage 4.

[0031] In order to avoid excessive rotation of the handle 8, which leads to disengagement of the driving tooth 5 and the driven wheel 34, the base 1 facing the handle 8 is also provided with a limiting groove 12, and the protrusion 6 provided on the outer wall surface of the linkage 4 slides in the limiting groove 12. Therefore, when the two ends of the limiting groove 12 respectively abut against the protrusion 6, the excessive rotation of the handle 8 can be prevented, thereby ensuring the rotation angle of the handle 8 to be controlled to ensure that the circuit board 31 can accurately obtain signals.

[0032] On the basis of the above scheme, in order to ensure the smoothness of the gear engagement and rotation process, one side of the linkage 4 facing the base 1 is also provided with a first shaft pin part 9, and a first bearing 2 is installed outside the first shaft pin part 9, and the outer ring of the first bearing 2 is embedded in the first installation groove 13 provided in the base 1. Thus, the linkage 4 can rotate smoothly under the action of the first bearing 2; at the same time, the handle 8 is also provided with a pipe 10, and one end of the pipe 10 penetrates through the first shaft pin part 9 and is flush with the outer side of the first shaft pin part 9. Therefore, on the one hand, the handle 8 and the linkage 4 have sufficient contact area to improve the connection strength after connection; on the other hand, the handle 8 can also rotate smoothly under the action of the first bearing 2 to improve the smoothness of the handle 8 when rotating.

[0033] Further, one side of the driven wheel 34 is provided with a second shaft pin part 37, and a second bearing 35 is installed outside the second shaft pin part 37, and the outer ring of the second bearing 35 is embedded in the second installation groove 14 provided on the base 1. Therefore, the driven wheel 34 can rotate smoothly and stably between one end of the base 1.

[0034] Further, one side of the driven wheel 34 is provided with a second shaft pin part 37, and a second bearing 35 is installed outside the second shaft pin part 37, and the outer ring of the second bearing 35 is embedded in the second installation groove 14 provided on the base 1. Therefore, the driven wheel 34 can rotate smoothly and stably between one end of the base 1.

[0035] As described above, the multi-axis positioning design is adopted to ensure the smoothness of the gear engagement and rotation process. In particular, the multi-axis positioning design makes the radial runout of the driven wheel 34 ≤0.05mm, ensuring that the rotation process is not jammed and has no abnormal sound.

[0036] Since the trigger 32 is fixed inside the third shaft pin part 33, and the trigger 32 is a magnet, the reliable installation space of the trigger 32 is provided while ensuring the reliable connection of the third shaft pin part 33 and the third bearing 36. Among them, the trigger 32 is preferably a magnet or a magnetic steel.

[0037] In order to meet the needs of different vehicle models, the circuit board 31 supports single / multi-channel analog signal output, such as (1 channel, 2 channels, 3 channels, etc.), and the output signal is a 0-5V / 0-12V voltage signal or a 4-20mA current signal, so the program can be customized according to the needs of the vehicle model. The detection module converts the angle signal into an analog signal, which is output to the vehicle electronic control system through a single / multi-channel circuit to realize acceleration control; if you need to expand the function, replace the driven wheel 34 with a linear Hall bracket / constant-on switch, which can realize linear Hall signal output / multi-function switch control.

[0038] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the described embodiments. Various changes, modifications, replacements, and variations of the embodiments can be made by those skilled in the art without departing from the principles and spirit of the present application, and still fall within the scope of the present application.
