[0030] Please see Figures 1 to 4 The image shows a first embodiment of the drive mechanism for the internal transmission clutch of the present invention. Figures 5 to 6 The second embodiment of the present invention is shown. Figures 7 to 8 The third embodiment of the present invention is shown. Figures 9 to 10 The fourth embodiment of the present invention is shown in the figure. Although there are four embodiments, they all belong to the same technical scope and function. The main components of the invention include: wheel axle 1, control claw slider 2, lever 3, electro-electric slider 4, lever sleeve 5, electro-electric bushing 6, and control ring 7. The axial displacement of lever 3 is driven by the magnetic field attraction and repulsion force of control ring 7 to push electro-electric slider 4 to rotate (swing type) or move laterally (direct push type) to drive lever 3 to move axially, so as to achieve the control claw slider 2 on lever 3 to control the clutch switching of the gearbox clutch structure.

[0031] Please refer to the following first. Figures 1 to 4In the first embodiment shown (swing type), the axle 1 is provided with a concave guide groove 11 for inserting the lever 3. The front end of the lever 3 is provided with a protruding control claw slider 2, and the rear section of the lever 3 is provided with a rack 31. The rear section of the lever 3 extends through the guide groove 51 provided in the lever sleeve 5. The guide groove 51 and the outside of the lever sleeve 5 are connected by a through assembly port 52. An electrically variable slider 4 that meshes with the rack 31 of the rear section of the lever 3 is provided in the assembly port 52. As shown in the figure, the electro-modulator slider 4 is provided with a toothed surface 41 that can engage with the rack 31 at the rear end of the lever 3, and is provided with N-pole and S-pole permanent magnets on the electro-modulator slider 4; the lever sleeve 5 is provided with an electro-modulator bushing 6 outside, and the lever sleeve 5 is fitted in a control ring 7 that can be positioned and rotated. The inner ring surface of the control ring 7 is provided with N-pole and S-pole permanent magnets or electromagnets 71, and the outer side of the control ring 7 is provided with a gear 72 that is rotated by an external force. When the gear 72 is rotated by an external force by a predetermined angle, the control ring 7 rotates synchronously by a predetermined angle, so that the N-pole or S-pole permanent magnets or electromagnets 71 provided on the inner ring surface switch different magnetic poles to correspond to the N-pole or S-pole of the electro-modulator slider 4.

[0032] like Figure 3 In the first embodiment shown (swing type), when the control ring 7 rotates by a predetermined angle so that the S-pole permanent magnet or electromagnet 71 set on its inner ring surface corresponds to the electro-slider 4, the electro-slider 4 is rotated counterclockwise by the magnetic field attraction and repulsion force, and its tooth surface 41 meshes with the rack 31 of the lever 3, causing the lever 3 to move laterally backward.

[0033] like Figure 4 In the first embodiment shown (swing type), when the control ring 7 rotates by a predetermined angle so that the N-pole permanent magnet or electromagnet 71 set on its inner ring surface corresponds to the electro-slider 4, the electro-slider 4 is rotated clockwise by the magnetic field attraction and repulsion force, and its tooth surface 41 meshes with the rack 31 of the lever 3, so that the lever 3 moves axially and forward.

[0034] Please refer to the following: Figures 5 to 6 In the second embodiment shown (direct-push single-pole control ring and bipolar electro-electric slider), the axial displacement of the lever 3 is driven by the magnetic attraction and repulsion force of the control ring 7 pushing the electro-electric slider 4 to move laterally, thereby driving the axial displacement of the lever 3, so as to achieve the clutch switching of the gearbox clutch structure by the control claw slider on the lever 3.

[0035] like Figure 5The second embodiment shown (direct-push type single-pole control ring and bipolar type electro-electric slider) is similar to the first embodiment in that it has a concave guide groove 11 on the axle 1 for inserting the lever 3. The front end of the lever 3 is provided with a protruding control claw slider 2. The rear section of the lever 3 extends through the guide groove 51 provided in the lever sleeve 5. The guide groove 51 and the outside of the lever sleeve 5 are connected by a through-hole assembly port 52. The only difference between the second embodiment (direct-push type) and the first embodiment is that an electro-electric slider 4 fixed to the rear section of the lever 3 is provided in the assembly port 52. When the control ring 7 rotates by a predetermined angle so that the S-pole permanent magnet or electromagnet 71 provided on its inner ring surface corresponds to the electro-electric slider 4, the magnetic field attraction and repulsion force causes the electro-electric slider 4 to move backward laterally, thereby causing the lever 3 to move axially backward.

[0036] like Figure 6 In the second embodiment shown (direct-push single-pole control ring and bipolar electro-electric slider), when the control ring 7 rotates by a predetermined angle so that the N-pole permanent magnet or electromagnet 71 set on its inner ring surface corresponds to the electro-electric slider 4, the magnetic field attraction and repulsion force causes the electro-electric slider 4 to move forward laterally, thereby causing the lever 3 to move axially laterally forward.

[0037] like Figure 7 and Figure 8 The third embodiment shown (direct-push bipolar control ring and unipolar electro-electric slider) is such that when the control ring 7 rotates by a predetermined angle so that the N-pole or S-pole permanent magnet or electromagnet 71 set on its inner ring surface corresponds to the electro-electric slider 4, the magnetic field attraction and repulsion force is used to make the electro-electric slider 4 move forward or backward, thereby causing the lever 3 to move axially forward or backward.

[0038] like Figure 9 and Figure 10 The fourth embodiment shown (direct-push bipolar control ring and bipolar electro-electric slider) is such that when the control ring 7 rotates by a predetermined angle so that the N-pole or S-pole permanent magnet or electromagnet 71 set on its inner ring surface corresponds to the electro-electric slider 4, the magnetic field attraction and repulsion force is used to make the electro-electric slider 4 move forward or backward, thereby causing the lever 3 to move axially forward or backward.

[0039] Therefore, in the first to fourth embodiments of the present invention, the axial displacement of the lever 3 is driven by the magnetic attraction and repulsion force of the control ring 7 to push the electro-electric slider 4 to rotate (swing type) or move laterally (direct push type), thereby driving the lever 3 to move forward or backward axially, so as to achieve the control claw slider 2 on the lever 3 to control the clutch switching of the transmission clutch structure.

[0040] In summary, the present invention can reliably and effectively produce the following practical benefits: (1) It can reliably provide an internal transmission gearbox clutch drive mechanism with a simple structure, few components, low cost, light size, and good practicality.

[0041] (2) It can provide a safe, practical and industrially applicable and economically efficient internal transmission clutch drive mechanism.

Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
