Detailed Implementation

[0031] Reference Figures 1-3 As shown, this utility model provides a technical solution: a coaxial structure for an electric drive axle assembly motor, including a motor body 1, a differential gear 2 installed at the output end of the motor body 1, a first drive shaft 3 fixedly connected to the other end of the differential gear 2, a second drive shaft 4 installed on the side of the motor body 1 away from the differential gear 2, a first positioning plate 5 fixedly connected to the side of the motor body 1, a second positioning plate 6 fixedly connected to the side of the differential gear 2, and a positioning rod 7 slidably connected to the inner wall of the second positioning plate 6, which is slidably connected to the inner wall of the first positioning plate 5. By setting the first positioning plate 5, the second positioning plate 6, and the positioning rod 7, a positioning effect can be achieved during the connection of the motor body 1 and the differential gear 2, and the positioning rod 7, which is slidably connected to the inner walls of the first positioning plate 5 and the second positioning plate 6, can move.

[0032] The following is a detailed explanation of its overall setup and function.

[0033] Reference Figures 1-6 As shown in this embodiment: a control plate 8 is fixedly connected to the end of the positioning rod 7 away from the first positioning plate 5. A first spring 9 is sleeved on the surface of the positioning rod 7, and both ends of the first spring 9 are fixedly connected to the control plate 8 and the second positioning plate 6, respectively. By setting the control plate 8, the first spring 9 can be installed on the surface of the positioning rod 7, and the position of the positioning rod 7 can be restricted by setting the first spring 9. A slide rod 10 is slidably connected to the inner wall of the second positioning plate 6. A limit block 13 is fixedly connected to the end of the slide rod 10 near the positioning rod 7. The limit block 13 is slidably connected to the inner wall of the second positioning plate 6, and the side of the limit block 13 near the first positioning plate 5 is arc-shaped. By setting the slide rod 10, the movement of the limit block 13 can be controlled, and the position of the positioning rod 7 can be restricted by setting the limit block 13. A pull plate 11 is fixedly connected to the end of the slide rod 10 away from the second positioning plate 6. A second spring 12 is sleeved on the surface of the slide rod 10, and both ends of the second spring 12 are fixedly connected to the pull plate 11 and the second positioning plate 6, respectively. By setting the pull plate 11, the slide bar 10 can be moved easily, and by setting the second spring 12, the position of the slide bar 10 can be restricted.

[0034] A support block 14 is fixedly connected to the surface of the motor body 1, and the support block 14 fits tightly against the differential gear 2. By setting the support block 14, the position can be restricted when connecting the motor body 1 and the differential gear 2. A rotating plate 15 is rotatably connected to the side of the support block 14 away from the second drive shaft 4, and a locking block 16 is installed on the side of the support block 14 near the rotating plate 15. The rotating plate 15, which is rotatably connected to the surface of the support block 14, can rotate, and the position of the rotating plate 15 can be restricted by setting the locking block 16. A sliding groove is opened on the side of the support block 14 near the locking block 16, and a slider 17 is slidably connected to the surface of the sliding groove on the support block 14. The slider 17 is fixedly connected to the locking block 16, and a fixing rod 18 is slidably connected to the inner wall of the slider 17. The fixing rod 18 is fixedly connected to the surface of the sliding groove on the support block 14, and a third spring 19 is sleeved on the surface of the fixing rod 18. The two ends of the third spring 19 are fixedly connected to the slider 17 and the support block 14, respectively. By setting slider 17, the block 16 and support block 14 can be connected while ensuring the movement of block 16. By setting third spring 19, the positions of slider 17 and block 16 can be restricted.

[0035] Working principle: When assembling the coaxial structure of the electric drive axle assembly motor, firstly, pulling the control plate 8 causes the positioning rod 7 to slide on the inner wall of the second positioning plate 6. The movement of the positioning rod 7 causes it to contact the arc surface of the limiting block 13, thereby causing the limiting block 13 to drive the sliding rod 10 to slide on the inner wall of the second positioning plate 6. After the pull plate 11 moves away from the positioning rod 7 and the control plate 8 moves away from the second positioning plate 6, under the action of the elastic force of the second spring 12, the limiting block 13 moves and locks into the positioning rod 7, restricting the position of the positioning rod 7. Differential 2 and the first drive shaft 3 approach the motor body 1 and the second drive shaft 4, causing differential 2 to contact the support block 14. Moving the locking block 16 causes the slider 17 to slide on the surface of the fixed rod 18, moving the locking block 16 away from the rotating plate 15, releasing the restriction on the position of the rotating plate 15. The rotating plate 15 rotates closer to the differential 2, releasing the locking block 16. Under the force of the third spring 19, the locking block 16 moves closer to the rotating plate 15, releasing the rotating plate 15. Under the action of gravity, the rotating plate 15 rotates closer to the locking block 16. At this time... Under the constraint of the locking block 16, the rotating plate 15 contacts the differential 2, and then the differential 2 is rotated, so that the second positioning plate 6 is close to the first positioning plate 5. Pulling the pull plate 11 causes the limiting block 13 to move away from the positioning rod 7, releasing the constraint on the positioning rod 7. At this time, under the action of the elastic force of the first spring 9, the positioning rod 7 moves closer to the first positioning plate 5, realizing the positioning effect between the motor body 1 and the differential 2. Then the two can be connected. By setting the first positioning plate 5, the second positioning plate 6 and the positioning rod 7, the positioning effect can be achieved when connecting the motor body 1 and the differential 2. At the same time, by setting the support block 14, the position of the motor body 1 and the differential 2 can be restricted, so that the two can be connected easily. By setting the sliding rod 10 and the limiting block 13, the position of the positioning rod 7 can be restricted, so that the positioning rod 7 can be used to connect the first positioning plate 5 and the second positioning plate 6 easily. By setting the rotating plate 15, the position of the motor body 1 and the differential 2 can be temporarily restricted, so that the two can be connected easily.
