Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3This utility model provides an embodiment of a new energy vehicle swing arm positioning fixture, including a base 1, a third rotating plate 14 rotatably connected inside the base 1, and a fixing mechanism provided on the upper surface of the third rotating plate 14; the fixing mechanism includes a second fixing block 18, the lower surface of the second fixing block 18 is fixedly connected to the upper surface of the third rotating plate 14, a second hydraulic rod 19 is fixedly connected to the inner wall of the second fixing block 18, a conical block 17 is fixedly connected to the output end of the second hydraulic rod 19, the inner surface of the conical block 17 is slidably connected to the outer wall of the second hydraulic rod 19, a plurality of connecting blocks 20 are slidably connected to the inner surface of the conical block 17, a sliding block 16 is fixedly connected to the outer wall of each of the plurality of connecting blocks 20, a second limiting block 21 is fixedly connected to the outer wall of the sliding block 16, a fixing plate 5 is fixedly connected to the upper surface of the sliding block 16, a first limiting block 4 is connected to the lower surface of the fixing plate 5, a second limiting rod 11 is slidably connected to the outer wall of the conical block 17, and the lower surface of the second limiting rod 11 is fixedly connected to the upper surface of the third rotating plate 14;

[0024] Specifically, by inserting the through hole of the swing arm into the outside of the first limiting block 4 and the fixing plate 5, the output end of the second hydraulic rod 19 drives the conical block 17 to move, causing the conical block 17 to slide along the outer wall of the second limiting rod 11. The movement of the conical block 17 causes the connecting block 20 to slide inside the conical block 17, and pushes the sliding block 16 to move, causing the sliding block 16 to drive the second limiting block 21 to move. In turn, the movement of the sliding block 16 drives the fixing plate 5 and the first limiting block 4 to move, and the movement of the fixing plate 5 expands outward to fix the swing arm.

[0025] The outer wall of the second limiting block 21 is slidably connected to the second rotating plate 10, and the interior of the second rotating plate 10 slides on the outer wall of the sliding block 16 and the fixed plate 5; the outer wall of the second rotating plate 10 is rotatably connected to the interior of the base 1, and the lower surface of the second rotating plate 10 is fixedly connected to the upper surface of the second limiting rod 11.

[0026] Specifically, the movement of the sliding block 16 causes the fixed plate 5 and the second limiting block 21 to move, so that the second limiting block 21 slides inside the second rotating plate 10, thereby limiting the movement of the sliding block 16. The second limiting rod 11 fixes the second rotating plate 10.

[0027] The upper surface of the third rotating plate 14 is fixedly connected to the first fixing block 8, the first fixing block 8 is fixedly connected to the first hydraulic rod 9, and the output end of the first hydraulic rod 9 is fixedly connected to the first rotating plate 3; the inner wall of the first rotating plate 3 is slidably connected to the outer wall of the fixing plate 5, and the outer wall of the first rotating plate 3 is rotatably connected to the limit plate 2; the lower surface of the limit plate 2 is fixedly connected to the first limit rod 7, and the outer wall of the limit plate 2 is slidably connected to the inside of the base 1.

[0028] Specifically, the output end of the first hydraulic rod 9 drives the first rotating plate 3 to move, causing the first rotating plate 3 to slide on the outer wall of the fixed plate 5. The movement of the first rotating plate 3 drives the limiting plate 2 to move, causing the limiting plate 2 to drive the base 1 to slide inside. The movement of the limiting plate 2 and the first rotating plate 3 causes the swing arm to move, and the first limiting block 4 limits the swing arm, thereby achieving the effect of clamping the swing arm and preventing the swing arm from sliding up and down.

[0029] A connecting rod 12 is rotatably connected inside the base 1. A rotating block 6 is fixedly connected to one end of the connecting rod 12, and a gear 13 is fixedly connected to the other end of the connecting rod 12. A gear ring 15 is fixedly connected to the upper surface of the third rotating plate 14, and the upper surface of the gear ring 15 is meshed with the outer wall of the gear 13.

[0030] Specifically, rotating the rotating block 6 drives the connecting rod 12 to rotate, causing the connecting rod 12 to rotate inside the base 1, which in turn drives the gear 13 to rotate. The gear 13 drives the gear ring 15 to drive the third rotating plate 14 to rotate inside the base 1. The rotation of the third rotating plate 14 causes the second limiting rod 11 and the second fixing block 18 to rotate, and the second rotating plate 10 to rotate inside the base 1. The sliding block 16 of the rotating plate 10 moves with the fixing plate 5, while the first rotating plate 3 rotates on the limiting plate 2. The rotation of the first rotating plate 3 achieves the effect of adjusting the angle of the swing arm.

[0031] Working principle: First, by inserting the through hole of the swing arm into the outer side of the first limiting block 4 and the fixed plate 5, the output end of the second hydraulic rod 19 drives the conical block 17 to move, causing the conical block 17 to slide along the outer wall of the second limiting rod 11. The movement of the conical block 17 causes the connecting block 20 to slide inside the conical block 17, pushing the sliding block 16 to move. The sliding block 16 then drives the second limiting block 21 to move, which in turn drives the fixed plate 5 and the first limiting block 4 to move. The movement of the fixed plate 5 expands outward to fix the swing arm. During the movement of the fixed plate 5, the output end of the first hydraulic rod 9 drives the first rotating plate 3 to move, causing the first rotating plate 3 to slide on the outer wall of the fixed plate 5. The movement of the first rotating plate 3 also drives the limiting plate 2 to move, causing the limiting plate 2 to drive the base 1 to slide inside. The swing arm is moved by the limiting plate 2 and the first rotating plate 3, and the swing arm is limited by the first limiting block 4, thereby achieving the effect of clamping the swing arm and preventing the swing arm from sliding up and down. After the swing arm is fixed, the connecting rod 12 is rotated by rotating the rotating block 6, so that the connecting rod 12 rotates inside the base 1 and drives the gear 13 to rotate. The gear 13 drives the gear ring 15 to drive the third rotating plate 14 to rotate inside the base 1. The rotation of the third rotating plate 14 drives the second limiting rod 11 and the second fixing block 18 to rotate, and the second rotating plate 10 rotates inside the base 1. Then, the sliding block 16 of the second rotating plate 10 moves with the fixing plate 5, and at the same time, the first rotating plate 3 rotates on the limiting plate 2. Thus, the rotation of the first rotating plate 3 achieves the effect of adjusting the angle of the swing arm.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
