A gear ring is sleeved on the outside of the first gear, a support is fixedly mounted on the gear ring, a second movable column is fixedly mounted on the support, and a fixed plate located inside the control box is fixedly mounted on the second movable column. A compression spring is sleeved on the outside of the second movable column, and the two ends of the compression spring abut against the fixed plate and the inner wall of the control box, respectively.

[0011] Optionally, the meshing component includes a second gear fixedly sleeved on the outside of the rotating shaft, a rotating ring rotatably connected inside the control box, and three arc-shaped toothed plates fixedly connected on the rotating ring, with the arc-shaped toothed plates meshing with the corresponding second gear.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0028] The hybrid passenger vehicle engine valve drive motor proposed in this embodiment, such as... Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the device includes a motor body 1, a control box 2 fixedly mounted on the outside of the motor body 1, three fixing rings 3 fixedly connected to the bottom of the control box 2, a first receiving hole 4 on the fixing ring 3, a first movable ball 5 inside the first receiving hole 4, and three clearance holes 6 adapted to the first movable ball 5 on the bottom inner wall of the control box 2. The control box 2 is equipped with a positioning structure for positioning the first movable ball 5. A first movable ring 7 is located below the fixing rings 3, a second receiving hole 8 on the first movable ring 7, a second movable ball 9 inside the second receiving hole 8, and a slider adapted to the first movable ball 5 installed on the second movable ring 9. An installation unit is fixedly mounted on the first movable ring 7. The operator moves the motor body 1 to be installed to the preset installation position, and the operator drives the first movable ring 7 to move away from the motor body 1, so that the first movable ring 7 moves to the preset installation position on the valve body. After the first movable ring 7 moves to the preset position, it is connected by the installation unit. The first movable ring 7 is fixedly installed on the valve body. According to the position of the valve stem axis, the operator drives the motor body 1 and the control box 2 to move relative to the valve stem, changing the position of the motor body 1. During the movement of the motor body 1, the first movable ball 5 rotates relative to the fixed ring 3, and the second movable ball 9 rotates relative to the first movable ring 7. The first movable ball 5 slides relative to the second movable ball 9 through the slider. When the control box 2 and the motor body 1 are adjusted to the preset position, the position of the first movable ball 5 is positioned by the positioning structure, so that the first movable ball 5 is fixed relative to the fixed ring 3 and the control box 2. Since the positions of several first movable balls 5 are fixed, the angle of the slider is fixed and locked, so that the second movable ball 9 is fixed relative to the first movable ring 7. This makes it possible to fix the motor body 1 and the control box 2 relative to the first movable ring 7 and the valve body. This allows for adjustment of the position of the output end of the motor body 1 according to actual needs, ensuring that the axis of the output end of the motor body 1 is consistent with the axis of the valve stem, thus improving the applicability.

[0029] In some optional specific embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the slider includes a first fixed post 12 fixedly mounted on the second movable ball 9, a first connecting post 11 fixedly mounted on the first movable ball 9, a first groove 13 formed on the first fixed post 12, a first movable post 14 slidably mounted in the first groove 13, and the top end of the first movable post 14 fixedly connected to the first connecting post 11. The positioning structure includes a pressing seat 15 disposed above the first movable ball 5, the pressing seat 15 located inside the control box 2, and a receiving groove 16 adapted to the first movable ball 5 formed at the bottom of the pressing seat 15. A second fixed post 17 is disposed above the pressing seat 15, and the second fixed post 17 and the inner wall of the control box 2 are fixedly connected by a connecting block 18. The second fixed post 17 is mounted with a connecting block 18. An elastic element adapted to the pressing seat 15 is provided. A second movable ring 19 is slidably sleeved on the outside of the second fixed post 17. The bottom of the second movable ring 19 and the pressing seat 15 are fixedly connected by at least one second connecting post 20. A support sleeve 21 is slidably sleeved on the outside of the second connecting post 20, and the support sleeve 21 is fixedly connected to the second fixed post 17. The control box 2 is equipped with a pushing mechanism for moving the three second movable rings 19. The pushing mechanism includes a rotating shaft 23 disposed above the second fixed post 17, and the rotating shaft 23 is rotatably connected to the control box 2. At least one protrusion 22 is fixedly connected to the top of the second movable ring 19. A support post 25 is disposed above the protrusion 22. The top of the support post 25 and the rotating shaft 23 are connected by a connecting post 25. The connecting plate 24 is fixedly connected, and the protrusion 22 has an inclined surface adapted to the support column 25. A worm gear 26 is fixedly sleeved on the outside of one of the rotating shafts 23. A worm 27 adapted to the worm gear 26 is rotatably connected to the control box 2. The control box 2 is equipped with a control unit adapted to the worm 27. Several rotating shafts 23 are connected by meshing parts. The control unit includes a first gear 28 fixedly installed on the worm 27, and the first gear 28 is located outside the control box 2. A gear ring 29 is sleeved on the outside of the first gear 28. A support part 30 is fixedly installed on the gear ring 29. A second movable column 31 is fixedly installed on the support part 30, and a fixed plate 32 located inside the control box 2 is fixedly installed on the second movable column 31. The second movable column 31 is fitted with a compression spring 33, and the two ends of the compression spring 33 abut against the inner wall of the fixed plate 32 and the control box 2 respectively. The meshing element includes a second gear 35 fixedly fitted on the outside of the rotating shaft 23. A rotating ring 34 is rotatably connected inside the control box 2. Three arc-shaped toothed plates 36 are fixedly connected on the rotating ring 34, and the arc-shaped toothed plates 36 mesh with the corresponding second gear 35. The elastic element includes a third movable column 37 fixedly installed on the top of the pressing seat 15. A second groove 38 is opened at the bottom of the second fixed column 17. The top of the third movable column 37 is located in the second groove 38, and the top of the third movable column 37 and the top inner wall of the second groove 38 are connected by a tension spring 39.

[0030] The operator drives the first movable ring 7 to move away from the motor body 1. The first movable ring 7 drives the first fixed column 12 to slide relative to the first movable column 14 through the second movable ball 9, changing the tilt angle between the first movable column 14 and the first fixed column 12. When the first movable ring 7 moves to the preset installation position on the valve body, the first movable ring 7 is fixedly installed on the valve body by the installation unit. When the operator adjusts the position of the motor body 1 and the control box 2, the first movable column 14 slides relative to the first fixed column 12, and the tilt angle between the first fixed column 12 and the first movable column 14 changes. At this time, the tension spring 39 is in a stretched state. The tension spring 39 applies tension to the third movable column 37 and the pressing seat 15, so that the first movable ball 5 is not in contact with the receiving seat. When the slots 16 are in contact and the top of the second movable ring 19 and the bottom of the support column 25 are in contact, and the positions of the motor body 1 and the control box 2 are adjusted, the operator drives the gear ring 29 to move away from the control box 2, so that the gear ring 29 disengages from the first gear 28, releasing the restriction on the position of the first gear 28. The gear ring 29 drives the second movable column 31 and the fixed plate 32 to move through the support part 30. The compression spring 33 is in a compressed state. The operator drives the first gear 28 and the worm 27 to rotate. The worm 27 drives the corresponding rotating shaft 23 to rotate through the worm wheel 26. The rotating shaft 23 drives a corresponding arc-shaped toothed plate 36 to rotate through the second gear 35. The arc-shaped toothed plate 36 drives the rotating ring 34 to rotate. The rotating ring 34 can then drive other... The arc-shaped toothed plate 36 rotates synchronously, and the arc-shaped toothed plate 36 drives the remaining two rotating shafts 23 to rotate synchronously through the second gear 35. The rotating shafts 23 drive the support column 25 to slide on the top of the second movable ring 19 through the connecting plate 24. When the bottom end of the support column 25 slides from the top of the second movable ring 19 to the inclined surface of the protrusion 22, as the rotating shaft 23 continues to rotate, the bottom end of the support column 25 slides on the inclined surface of the protrusion 22. The support column 25 pushes the protrusion 22, the second movable ring 19, the second connecting column 20 and the first movable ball 5 to move downward, and the second connecting column 20 slides relative to the support sleeve 21. Through the design of the support sleeve 21 and the second connecting column 20, the pressing seat 15 and the second movable ring 19 move downward smoothly relative to the second fixed column 17. 5 drives the third movable column 37 to slide relative to the second groove 38, and the length of the tension spring 39 increases. When the first movable ball 5 contacts the inner wall of the receiving groove 16, the pressing seat 15 presses the first movable ball 5 to fix the first movable ball 5 relative to the pressing seat 15. The operator releases the gear ring 29, and the compressed spring 33 drives the fixed plate 32, the second movable column 31, the support part 30 and the gear ring 29 to move in the opposite direction so that the gear ring 29 is once again fitted on the outside of the first gear 28. The gear ring 29 limits the position of the first gear 28 and the worm 27 to prevent the worm 27 from rotating relative to the control box 2 due to non-human factors. This allows the rotating shaft 23 and the support column 25 to be fixed relative to the control box 2, so that the pressing seat 15 and the first movable ball 5 remain fixed relative to the control box 2.

[0031] In some optional specific embodiments, such as Figure 1 , Figure 6 and Figure 7 As shown, the mounting unit includes a connecting frame 41 fixedly mounted on the side of the first movable ring 7 away from the motor body 1. A mounting base 10 is fixedly connected to the bottom end of the connecting frame 41. A through hole 42 is provided on the mounting base 10. A limiting block 44 is contacted at the top of the mounting base 10. A lead screw 43 is fixedly connected to the bottom of the limiting block 44, and the lead screw 43 passes through the through hole 42. A locking component adapted to the limiting block 44 is mounted on the mounting base 10. The locking component includes a movable seat 45 disposed above the mounting base 10. The bottom of the movable seat 45 has an opening... There is a limiting groove 46, and the limiting block 44 is located in the limiting groove 46. The movable seat 45 is fixedly installed with an iron plate 47. The mounting seat 10 is equipped with a magnetic suction device adapted to the iron plate 47. The magnetic suction device includes a guide post 48 fixedly installed on the top of the mounting seat 10, and the guide post 48 penetrates the iron plate 47. A magnetic ring 40 located below the iron plate 47 is fixedly sleeved on the outside of the guide post 48. The top of the magnetic ring 40 is in contact with the bottom of the iron plate 47. A magnetic disk 49 located above the iron plate 47 is fixedly connected to the top of the guide post 48.

[0032] Before the first movable ring 7 is fixedly installed with the valve body, the operator drives the movable seat 45 and the iron plate 47 to move upwards, so that the iron plate 47 is no longer magnetically attracted to the magnetic ring 40, and the limiting block 44 disengages from the limiting groove 46. Then, the operator drives the movable seat 45 and the iron plate 47 to rotate relative to the guide post 48, so that the movable seat 45 is no longer directly above the limiting block 44, and at this time, the bottom of the iron plate 47 and the magnetic disk 49 are magnetically attracted and fixed. Then, the operator drives the limiting block 44 and the lead screw 43 to move, so that the lead screw 43 disengages from the through hole 42. The operator drives the first movable ring 7 to move away from the motor body 1, so that when the first movable ring 7 moves to the preset installation position on the valve body, the operator drives the limiting block 44 and the lead screw 43 to move, so that the bottom end of the lead screw 43 passes through the through hole 42. Then, the operator drives the limiting block 44 and the lead screw 43 to rotate. The bottom end of the lead screw 43 is screwed into the threaded hole on the valve body until the bottom of the limit block 44 contacts the top of the mounting seat 10. The mounting seat 10 is clamped and fixed between the limit block 44 and the valve body, so that the first movable ring 7 and the mounting seat 10 are fixed relative to the valve body. Then, the operator drives the movable seat 45 and the iron plate 47 to rotate in the opposite direction relative to the guide post 48. The limit groove 46 moves again to the top of the limit block 44. The operator drives the movable seat 45 and the iron plate 47 to move down so that the limit block 44 is inserted into the limit groove 46. The position of the limit block 44 is limited by the movable seat 45 and the limit groove 46, so as to prevent the limit block 44 and the lead screw 43 from rotating relative to the mounting seat 10 and the valve body due to non-human factors. At this time, the iron plate 47 and the magnetic ring 40 are magnetically attracted and fixed, so as to prevent the movable seat 45 and the iron plate 47 from shaking vertically relative to the mounting seat 10.

[0033] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the invention is limited to these examples; within the framework of the invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.
