The right end inner wall of the movable frame 12 is fixedly connected to one end of the positioning spring 13. When the pull plate 14 moves to the right, the positioning spring 13 will be compressed. When resetting, the pull plate 14 is reset by the elastic force of the positioning spring 13, and the other end of the positioning spring 13 is fixedly connected to the right end outer wall of the pull plate 14. The pull plate 14 and the card block 15 are respectively penetrated and slidably connected to the inner wall of the movable frame 12. The movable frame 12 is respectively provided with slots corresponding to the pull plate 14 and the card block 15, so that the pull plate 14 and the card block 15 can slide along the slots, and the card block 15 is plugged into the inner wall of the sleeve frame 11.

[0033] Reference Figure 1-Figure 3The limit mechanism includes a limit block 10, which is an inclined surface. When the inclined surface is squeezed, the limit block 10 will slide along the inner wall of the fixed plate 1. The left end of the limit block 10 is elastically connected to the fixed plate 1 through the return spring 9. The limit block 10 is slidably connected to the inner wall of the fixed plate 1. The left end of the limit block 10 is fixedly connected to one end of the return spring 9. When the limit block 10 moves to the left, the return spring 9 is compressed. When resetting, the limit block 10 is brought back to the original position by the elastic force of the return spring 9. The other end of the return spring 9 is fixedly connected to the inner wall of the left end of the fixed plate 1, the outer wall of the limit block 10 is plugged into the outer wall of the plug plate 6, and the outer wall of the plug plate 6 is provided with a plurality of openings corresponding to the limit block 10, so that the limit block 10 can be plugged into its openings to position the entire connecting plate 5 in one direction, and the plug plate 6 is inserted through the inner wall of the fixed plate 1, and a notch corresponding to the plug plate 6 is provided on the fixed plate 1, so that the plug plate 6 can pass through the notch, and the outer wall of the plug plate 6 contacts the inner side wall of the elastic sleeve 7.

[0034] Working principle: First, when the fixed plate 1 and the connecting plate 5 need to be folded and stored, it is only necessary to disassemble the bearing seat 8 from the fixed plate 1 and the connecting plate 5 by bolts, remove the bearing seat 8 from the top of the fixed plate 1 and the connecting plate 5, then pull out the plug plate 6 from the inner side of the elastic sleeve 7, and then rotate the connecting plate 5 with the sleeve frame 11, the movable frame 12 and the plug plate 6 clockwise, so that the fixed plate 1 and the connecting plate 5 gradually move closer and insert the plug plate 6 into the inner wall notch of the fixed plate 1, so that the left end of the plug plate 6 squeezes the limit The inclined surface of the positioning block 10 allows the limiting block 10 to move to the left and compress the reset spring 9. When the limiting block 10 coincides with the outer wall opening of the plug plate 6, the reset spring 9 is used to bring the limiting block 10 to reset to the right, so that the limiting block 10 is plugged into the outer wall opening of the plug plate 6, and the plug plate 6 continues to penetrate the inner wall of the fixed plate 1 so that the limiting block 10 is continuously squeezed by the opening of the plug plate 6, so that the limiting block 10 is continuously plugged into and positioned with the opening of the plug plate 6, and the fixed plate 1 and the connecting plate 5 are folded into a V-shape for storage.

[0035] When the fixing plate 1 and the connecting plate 5 need to be used, the limiting block 10 only needs to be pushed to the left to move the limiting block 10 to the left and compress the return spring 9, so that the limiting block 10 and the outer wall opening of the plugging plate 6 are separated, and then the connecting plate 5, the plugging plate 6, the sleeve frame 11, and the movable frame 12 are rotated counterclockwise to the right to slowly pull the plugging plate 6 out of the inner wall notch of the fixing plate 1, so that the fixing plate 1 and the connecting plate 5 are in the Figure 1 State, then pull up the elastic sleeve 7 to let the plug plate 6 pass through the middle of the elastic sleeve 7, then loosen the elastic sleeve 7 and use the elastic force of the elastic sleeve 7 to cover the plug plate 6 for positioning, and then use the existing installation technology to install the bearing seat 8 and the new energy vehicle connecting shaft, and finally connect the top of the fixing plate 1 and the connecting plate 5 to the bottom end of the bearing seat 8 by tightening bolts.

[0036] When it is necessary to adjust the height of the connection between the chassis of the new energy vehicle and the movable frame 12, it is only necessary to pull the pull plate 14 to the right so that the pull plate 14 moves the block 15 to the right and compress the positioning spring 13, so that the block 15 is separated from the inner wall groove of the sleeve frame 11, and then the movable frame 12 is moved upward to make the movable frame 12 contact with the connection between the chassis of the new energy vehicle, so that the top of the movable frame 12 and the chassis connection are fixed with the existing technology, and finally the pull plate 14 is released and the reverse elastic force of the positioning spring 13 is used to reset the pull plate 14 and the block 15, so that the pull plate 14 and the block 15 are reset to the left, so that the block 15 is plugged into the inner wall groove of the sleeve frame 11, and the installation length of the entire movable frame 12 can be adjusted. When it needs to be adjusted again, just follow the above steps.
