Figure 5 and Figure 6 As shown, the cam rotating lever 213 is a V-shaped lever, and the first cam end 213A of the left arm of the V-shaped lever is specifically a cylindrical boss of the lever arm fork, and the cylindrical boss is connected to the latch 211; the second cam end 213B of the right arm of the V-shaped lever is a lever arm cam, wherein the first convex part 213B-1 is a small cylindrical boss with a slightly smaller shape, and the second convex part 213B-3 is a large cylindrical boss with a slightly larger shape, and there is a concave part connecting the small cylindrical boss and the large cylindrical boss, namely the first concave part 213B-2. Figure 4As shown, the driving baffle assembly 300 is provided with a first baffle 310 and a second baffle 320, and the first baffle 310 and the second baffle 320 cooperate with the cam rotating lever 213 during the clutch process, so that the driving baffle assembly 300 and the limiting assembly 210 are coupled and linked. In this embodiment, the coupling process of the driving baffle assembly 300 and the limiting assembly 210 is as follows:

[0079] In the process of switching from the engaged state to the disengaged state, the first baffle plate 310 abuts against the first protrusion 213B-1 to drive the latch 211 to slide from the first position to the second position and remain at the second position;

[0081] Taking the first gear 011 as the input gear, the second gear 012 as the output gear, and the gear shaft 013 as the output shaft connected to the wheel as an example, the following Figure 7 Introduce the complete working process of the clutch:

[0082] In this embodiment, if Figure 1 When the latch 211 abuts downward against the first limiting groove 220, the output gear and the input gear mesh and transmit, and the output shaft drives the wheel to rotate; when the gearbox needs to stop outputting torque, the output end of the drive assembly 400 moves to the right along the axial direction of the output shaft, and the first baffle plate 310 abuts against the first convex portion 213B-1, driving the cam rotating lever 213 to rotate around the rotating shaft on the base 100, and the compression spring is compressed, and the latch 211 connected to the first cam end 213A moves upward from the first position to the second position, disengaging from the first limiting groove 220, and the latch 211 is no longer limited, and the clutch device enters a preparatory sliding state, such as Figure 7 a; such as Figure 7 As shown in FIG. 2 b, the first baffle plate 310 abuts against the first protrusion 213B-1, the latch 211 is fully lifted, and the drive assembly 400 drives the output gear connected to the base 100 to slide to the right and gradually disengage from the input gear; Figure 7 As shown in FIG. 3 , the driving assembly 400 drives the output gear to completely disengage from the input gear until the latch 211 is aligned with the second limiting groove 230, and the first end surface of the driving baffle assembly 300 is abutted against the second limiting stop 250; Figure 7As shown in FIG. d, the output end of the drive assembly 400 moves to the left along the axial direction of the output shaft, the first protrusion 213B-1 disengages from the abutment with the first baffle plate 310, the compression spring rebounds, the latch 211 falls downward and abuts against the second limiting groove 230. At this time, the input gear and the output gear are disengaged. Since the limiting assembly 210 abuts against the second limiting groove 230, the output gear is limited in a disengaged state, the torque transmission of the gearbox is interrupted, the wheels no longer rotate, and the train stops.

[0083] When the gearbox output torque is required, such as Figure 7 As shown in FIG. 4 , the driving assembly 400 drives the driving baffle assembly 300 to move leftward and couple with the limiting assembly 210, and the second baffle 320 abuts against the second protrusion 213B-3 and slides along the outer edge of the second protrusion 213B-3, driving the latch 211 to slide from the first position to the second position along the Y direction, and the latch 211 begins to disengage from the second limiting groove 230; Figure 7 As shown in FIG. 5 , the second baffle plate 320 leaves the second convex portion 213B-3 and enters the first concave portion 213B-2 and abuts against the first concave portion 213B-2, and the latch pin 211 completely disengages from the second limiting groove 230 and no longer limits the output gear; Figure 7 As shown in FIG. g, the driving baffle assembly 300 is coupled with the limiting assembly 210, the second baffle 320 abuts against the first recess 213B-2, and the driving assembly 400 drives the base 100 and the output gear connected thereto to move leftward; Figure 7 h, until the latch 211 is aligned with the first limiting groove 220, and the second end face of the output gear abuts against the first limiting stop 240; then, the drive assembly 400 moves to the right and enters Figure 1 In the state, the latch 211 falls downward along the Y direction in the base 100 under the rebound force of the compression spring, abuts against the first limiting groove 220, the output gear and the input gear are meshed for transmission, and the output shaft drives the wheel to rotate.

[0084] In an optional embodiment provided by the present invention, Figure 1 As shown, the limiting unit 200 further includes a first limiting stop 240, which is disposed on the gear shaft 013. In the meshing state, the second end face of the second gear 012 abuts against the first limiting stop 240. In this embodiment, the first limiting stop 240 is disposed on the gear shaft 013, and in the meshing state, the first limiting stop 240 abuts against the second end face of the second gear 012 to further limit the position of the second gear 012, so that the second gear 012 and the first gear 011 can be more stably meshed.

[0085] In another optional embodiment provided by the present invention, Figure 1As shown, the limiting unit 200 further includes a second limiting stop 250. In the separated state, the second limiting stop 250 abuts against the first end surface of the driving baffle assembly 300 so that the limiting assembly 210 is aligned with the second limiting groove 230. In this embodiment, the second limiting stop 250 is provided. In the separated state, the second limiting stop 250 abuts against the first end surface of the driving baffle assembly 300 so that the limiting assembly 210 is aligned with the second limiting groove 230, thereby ensuring that the sliding distance of the second gear 012 is within the clutch stroke.

[0087] In the embodiment provided by the present invention, the base 100 can be set to be annular and connected to the first end face of the second gear 012. The annular base 100 is slidably mounted on the gear shaft 013. When the clutch device uses multiple evenly arranged drive components 400 to drive the second gear 012 connected to the base 100 to clutch, the force applied is evenly distributed along the first end face of the second gear 012 through the annular base 100, thereby improving the stability of the clutch device operation.

[0088] In the embodiment provided by the present invention, the second gear 012 is connected to the gear shaft 013 via a spline; preferably, the annular base 100 is connected to the gear shaft 013 via a spline.
