[0033] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a lifting device for repairing new energy vehicles, including a support frame 1, four support frames 1 are symmetrically arranged, and a connecting frame 2 is installed near the top of the four support frames 1. The support frame 1 and the connecting frame 2 are positioned and fastened by positioning bolts 3. A protruding plate 4 is protrudingly provided on the outer edge of the support frame 1, and the protruding plate 4 is vertically fixed to the ground by fixing bolts 41. A slide is provided on one side of the adjacent four support frames 1.

[0034] A receiving plate 6 is clamped and installed between the above four support frames 1. An observation cavity is opened at the center of the receiving plate 6. Sliding plates 7 are inserted and installed on both sides of the observation cavity. Adjustment grooves are opened at both ends of the observation cavity. Limit blocks 71 are protrudingly provided at both ends of the sliding plate 7. An adjustment component 8 for assisting the position adjustment of the limit block 71 is installed in the adjustment groove. The adjustment component 8 includes a rotating rod 9 rotatably set in the adjustment groove. The rotating rod 9 is passed through and installed in the limit block 71. The limit block 71 is threadedly matched with the rotating rod 9. A worm gear 10 is sleeved and installed at the middle section of the rotating rod 9. An adjusting motor 11 for assisting the rotation of the worm gear 10 is installed inside the receiving plate 6. A worm 12 is installed at the front end of the shaft of the adjusting motor 11, and the worm gear 10 and the worm 12 cooperate for transmission.

[0035] Through the cooperation between the sliding plate 7 and the adjusting component 8, the adjusting motor 11 drives the worm 12 to rotate as a whole, and the worm wheel 10 and the worm 12 cooperate with each other to rotate the worm wheel 10 as a whole, and then the rotating rod 9 rotates as a whole, and the limit block 71 cooperates with the rotating rod 9 to move the limit block 71 as a whole and drive the sliding plate 7 to move as a whole, thereby adjusting the observation cavity to a specified width. The overall size of the observation cavity can be adjusted according to the size of the vehicle, etc., so as to meet the observation and maintenance needs of vehicle chassis of different sizes.

[0036] A scale plate 22 is vertically embedded on the inner side of the support frame 1, and scale lines are engraved on the scale plate 22. Through the set scale lines 22, the overall stability of the receiving plate 6 during the adjustment process can be effectively judged during work, ensuring that subsequent work proceeds smoothly.

[0037] like Figure 1 and Figure 3 and Figure 4 As shown, both sides of the receiving plate 6 are protruded to form a protruding plate 62, a rotating rod 13 is provided in the slide for vertical rotation, the protruding plate 62 is sleeved and installed on the rotating rod 13, and the rotating rod 13 and the protruding plate 62 are threadedly matched. A lifting motor 14 is installed at the top of the support frame 1 to assist the rotation of the rotating rod 13.

[0038] By cooperating between the rotating rod 13 and the lifting motor 14 arranged on the support frame 1 and the protruding plate 62 on the receiving plate 6, threaded lifting can be used instead of hydraulic lifting during operation, and the receiving plate 6 will not be crushed and fallen as a whole in the event of a fault, thereby ensuring the overall safety of the receiving plate 6.

[0039] A limit strip 15 is symmetrically and vertically fixed within the slideway. A limit groove for the limit strip 15 to slide is provided on the protruding plate 62. Several positioning holes 151 are equidistantly provided on the limit strip 15. A positioning cavity is provided within the protruding plate 62. A limit assembly 16 is installed within the positioning cavity and engages with the positioning holes 151. The limit assembly 16 includes a positioning pin 21 symmetrically slidably provided within the positioning cavity. An ejection spring 20 is installed within the positioning cavity to assist in pushing the positioning pin 21. A slideway is provided in the middle section of the protruding plate 62. A connecting plate 19 is slidably provided within the slideway. A screw 18 is rotatably provided within the slideway. The screw 18 and the connecting plate 19 are threadedly engaged. The positioning pin 21 and the connecting plate 19 are connected and fixed by a connecting belt 201. A servo motor 17 is installed within the receiving plate 6 to assist in the rotation of the screw 18.

[0040] By cooperating with the limit assembly 16 set inside the protruding plate 62 and the positioning hole 151 on the limit bar 15, the servo motor 17 can be started after the connecting plate 6 is adjusted to the specified height. The servo motor 17 drives the screw rod 18 to rotate as a whole, and the screw rod 18 is threadedly engaged with the connecting plate 19, so that the connecting plate 19 moves as a whole, and then the connecting plate 19 moves as a whole toward the rotating rod 13. The compressed ejection spring 20 pushes the positioning pin 21, so that the positioning pin 21 is inserted and installed in the positioning hole 151, thereby completing the overall positioning processing between the protruding plates 62, and can perform auxiliary positioning processing on the protruding plate 62 in subsequent work, which can effectively reduce the overall force on the rotating rod 13 and try to avoid the bending of the rotating rod 13 after the force is applied. At the same time, it can further improve the overall safety of the connecting plate 6 and avoid the overall falling of the connecting plate 6 after the rotating rod 13 breaks.

[0041] A receiving platform 5 for the car to open the receiving plate 6 is symmetrically installed on one side of the receiving plate 6. The receiving platform 5 is a wedge-shaped block structure, and an anti-slip pattern is protruding from the top of the receiving platform 5. The anti-slip pattern can provide sufficient friction when the car moves, ensuring that subsequent work proceeds smoothly.

[0042] The working principle of the technical solution provided by the utility model is as follows:

[0043] When the car needs to be lifted or lowered, the car is driven to the top of the receiving plate 6 through the receiving platform 5, and the vehicle receiving plate 6 stops rotating when the rear tire reaches the blocking plate 61, and the lifting motor 14 is started synchronously. The lifting motor 14 drives the rotating rod 13 to rotate as a whole, and the rotating rod 13 is threadedly engaged with the protruding plate 62, so that the protruding plate 62 moves as a whole. During the movement of the protruding plate 62, the receiving plate 6 is driven to rise as a whole, and the overall height of the receiving plate 6 is effectively determined by the scale lines on the scale plate 22.

[0044] After the connecting plate 6 is adjusted to the specified height, the servo motor 17 is started. The servo motor 17 drives the screw rod 18 to rotate as a whole. The screw rod 18 is threadedly engaged with the connecting plate 19, so that the connecting plate 19 moves as a whole, and then the connecting plate 19 moves as a whole toward the rotating rod 13. The compressed ejection spring 20 pushes the positioning pin 21, so that the positioning pin 21 is inserted and installed in the positioning hole 151, thereby completing the overall positioning process between the protruding plates 62. When the height of the connecting plate 6 needs to be adjusted again, the positioning pin 21 can be pushed out of the positioning hole 151.

[0045] When the overall width of the observation chamber needs to be adjusted, the adjustment motor 11 is started synchronously, and the adjustment motor 11 drives the worm 12 to rotate as a whole. The worm wheel 10 and the worm 12 cooperate with each other to rotate the worm wheel 10 as a whole, and then the rotating rod 9 rotates as a whole. The limit block 71 cooperates with the rotating rod 9 to move the limit block 71 as a whole and drive the sliding plate 7 to move as a whole, thereby adjusting the observation chamber to the specified width.

[0046] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
