There is a gap between the first magnet 55 and the second magnet 62, a gap between the first magnet 55 and the fifth magnet 21, and a gap between the fourth magnet 57 and the third magnet 42.During the sliding process of slider 2 5 relative to slider 1 4, the two first magnets 55 are always in a state of not being blocked by slider 1 4, so that the two first magnets 55 and the fifth magnet 21 and the second magnet 62 have a stable matching relationship; the first guide structure includes a guide groove 56 provided on a side of the slider body 51 close to the bottom shell 2, and a guide rib 41 adapted to the guide groove 56 is provided on the slider 1 4. The slider 1 4 is slidably provided on the slider 2 5 through the matching of the guide rib 41 and the guide groove 56; the guide groove 56 is parallel to the two first magnets 55, and the fourth magnet 57 is perpendicular to the two first magnets 55; the second guide structure includes a guide rib 43 provided on the slider 1 4, and a guide rib 41 adapted to the guide groove 56 is provided on the bottom shell 2. The guide groove 22 corresponds to the rib 43. The entire slider assembly 3 can slide relative to the bottom shell 2 through the cooperation of the guide rib 43 and the guide groove 22. The slider 1 4 is arranged in a right-angled shape, including a right-angle portion 1 44 and a right-angle portion 2 45 perpendicular to the right-angle portion 1 44. The guide rib 41 is arranged on the right-angle portion 1 44 and extends to the right-angle portion 2 45. The two third magnets 42 are arranged on the right-angle portion 2 45. The spatial projection area of ​​the slider 1 4 is smaller than the projection area of ​​the slider 2 5. There are two guide ribs 43, one on the right-angle portion 1 44 and the other on the right-angle portion 2 45. Two corresponding guide grooves 22 are provided.

[0032] In this embodiment, the upper cover 1, the bottom shell 2, and the slider assembly 3 are components of the shift control mechanism, wherein the control rocker 13 passes through the upper cover 1, the through-hole 54, and the through-hole 61 in order from top to bottom. In this embodiment, when the automatic gear is switched, the control rocker 13 is located in the automatic gear hole 11. As the control rocker 13 moves in the automatic gear hole 11, the gear is switched from the initial gear 0 to the +1 gear / +2 gear, or from the initial gear 0 to the -1 gear / -2 gear. For details, see Figure 8 , Figure 9 .

[0033] Specifically, in Figure 8, the gear position is switched from the initial gear position 0 to the +1 gear / +2 gear. In this specific embodiment, the two fifth magnets 21 on the bottom shell 2 have an N-pole on the left and an S-pole on the right. The two first magnets 55 on the slider 2 5 have an S-pole on the left and an N-pole on the right. The two second magnets 62 on the slider 3 6 have an N-pole on the left and an S-pole on the right. In the initial position of gear 0, the two fifth magnets 21 on the bottom shell 2, the two first magnets 55 on the slider 2 5, and the two second magnets 62 on the slider 3 6 are arranged in a one-to-one correspondence in the vertical direction. When shifting from the initial position of gear 0 to gear +1, the entire slider assembly 3 slides relative to the bottom housing 2 via a second guide structure. Specifically, the second guide structure comprises a guide groove 22 provided on the bottom housing 2 and a guide rib 43 provided on slider 1 4. Because the two fifth magnets 21 on the bottom housing 2 and the corresponding two first magnets 55 on slider 2 5 have different polarities, the attraction between the two magnets must be overcome when shifting gears via the operating rocker 13. This ensures a smooth shifting feel. Specifically, by adjusting the spacing between the magnets or the magnetic strength, the operating force and feedback clarity can be flexibly adjusted. When shifting from gear +1 to gear +2, slider 2 5 slides relative to slider 3 6. At this point, the operating rocker 13, which passes through the through-hole 54, moves within the through-hole 61. Furthermore, because slider 3 6 is slidably disposed within the guide channel 53, the sliding motion of slider 2 5 relative to slider 3 6 is achieved. During this time, slider 2 5 must overcome the attraction between first magnet 55 and second magnet 62 as it slides relative to slider 3 6, thereby improving the operating feel. After switching from the initial position of gear 0 to gear +1, the entire slider assembly 3 returns to its original position relative to the bottom housing 2. After switching from gear +1 to gear +2, slider 2 5 returns to its original position relative to slider 3 6.

[0034] And in Figure 9Figure 2 shows a gear shift from the initial gear position 0 to -1 / -2. The two fifth magnets 21 on the bottom housing 2 have an N pole on the left and an S pole on the right. The two first magnets 55 on the second slider 5 have an S pole on the left and an N pole on the right. The two second magnets 62 on the third slider 6 have an N pole on the left and an S pole on the right. In the initial position of 0, the two fifth magnets 21 on the bottom housing 2, the two first magnets 55 on the second slider 5, and the two second magnets 62 on the third slider 6 are arranged in a one-to-one vertical correspondence. When switching from the initial position of 0 to -1, the slider assembly 3 as a whole slides relative to the bottom housing 2 in the opposite direction to the switching from the initial position of 0 to +1. When switching from -1 to -2, the second slider 5 slides relative to the third slider 6 in the opposite direction to the switching from +1 to +2. Among them, after completing the switch from the initial position of gear 0 to gear -1, the slider assembly 3 as a whole will be reset relative to the bottom shell 2; after completing the switch from gear -1 to gear -2, the slider 2 5 will be reset relative to the slider 3 6.

[0035] exist Figure 10 The figure shows the switch between D and M gears. Here, slider 2 5 slides relative to slider 1 4 via a second guide structure, which consists of a guide slot 56 on slider 2 5 and a guide rib 41 on slider 1 4. Specifically, both third magnets 42 on slider 1 4 can be configured with north poles, while the fourth magnet 57 on slider 2 5 is configured with south poles. When switching from D to M gear, slider 2 5 slides relative to slider 1 4, and the fourth magnet 57 moves from a position opposite one of the third magnets 42 to a position opposite the other third magnet 42. When switching from M to D gear, slider 2 5 slides relative to slider 1 4 and resets, and the fourth magnet 57 also resets. After switching from D to M gear or vice versa, slider 2 5 remains fixed relative to slider 1 4, i.e., self-locking.

[0036] exist Figure 11In the figure, the switching from the initial gear to the + gear or the - gear in the manual gear is shown. Specifically, the relative positions of the first magnet 55 and the fifth magnet 21 are changed by sliding the slider assembly 3 as a whole relative to the bottom shell 2. Specifically, the two fifth magnets 21 on the bottom shell 2 are the N pole and the S pole from left to right, while the two first magnets 55 on the slider 25 are the S pole and the N pole from left to right. In the initial gear position, the two fifth magnets 21 and the two first magnets 55 are arranged in a one-to-one correspondence. When switching from the initial gear position to the + gear, the slider assembly 3 as a whole slides to the left relative to the bottom shell 2; when switching from the initial gear position to the - gear, the slider assembly 3 as a whole slides to the right relative to the bottom shell 2. After switching from the initial gear to the + gear or the - gear, the slider assembly 3 as a whole will be reset relative to the bottom shell 2.

[0037] And, as Figure 6 As shown, after the entire slider assembly 3 slides relative to the bottom housing 2, the rubber pads 65 on both sides of the slider 3 6 abut against the limit blocks 14 of the upper cover 1. At this point, when the operating slider 2 5 slides relative to the slider 3 6, the slider 2 5 and the slider 1 4 also translate and slide left and right relative to the upper cover 1 and the slider 3 6. The purpose of providing the limit blocks 14 and rubber pads 65 is to provide cushioning and vibration absorption. When the rubber pads 65 abut the limit blocks 14, they prevent the harshness caused by direct hard collisions, reduce noise, stabilize gear shifting, and enhance the smoothness and premium feel of the gear shifting operation. Furthermore, providing the limit ring 15 on the operating rocker 13 also provides cushioning, noise reduction, and stable gear shifting, as well as enhancing the smoothness and premium feel of the operation.

[0038] In addition, there is a gap between the first magnet 55 and the second magnet 62, there is a gap between the first magnet 55 and the fifth magnet 21, and there is a gap between the fourth magnet 57 and the third magnet 42, that is, a non-contact design is adopted between the relative magnets, and a magnetic holding structure without mechanical limit is realized through the principle of opposite attraction between magnets. In this way, compared with traditional mechanical shifting, there is no physical friction and wear, and the service life is greatly improved. In addition, there is no mechanical collision sound due to magnetic adsorption, and the vibration absorption characteristics of the rubber pad 65 and the rubber ring can effectively reduce the noise during the shifting operation, there is no jamming during the shifting process, and the operation is smoother.

[0039] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
