[0002] A lift is a device specifically designed for the removal, replacement, and repair of power batteries in new energy vehicles. It safely elevates the battery underneath the vehicle to a certain height, allowing maintenance personnel to conveniently remove and install the battery without having to bend over or enter the confined space beneath the vehicle, thereby improving both efficiency and safety.

[0003] In the prior art, a Chinese utility model patent with publication number "CN215756163U" and patent title "Lift for Replacing New Energy Batteries" discloses a lift. The patent describes technical solutions such as "a quick clamp is installed on the pallet to ensure that when adjusted to the appropriate position, the pallet and the second bracket are relatively fixed, eliminating safety hazards; at the same time, a limit plate is installed at the bottom of the pallet, which not only increases the sliding distance of the pallet but also prevents the pallet and the second bracket from slipping, thereby enhancing safety."

[0004] However, in actual use of this technical solution, after the new energy battery on the new energy vehicle is removed and placed on the platform, when the platform is adjusted by the lift body to lift, lower or tilt the new energy battery, due to the lack of a fixing measure for the new energy battery, the new energy battery on the platform may slip or tilt and fall, thereby causing the new energy battery to fall from the platform to the ground and be damaged;

[0005] Therefore, in order to solve the above technical problems, the present invention proposes a lifting machine for replacing new energy batteries. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 - Figure 3As shown, a lift for replacing new energy batteries includes a lift body 1 and a support platform 2, and a clamping and fixing mechanism 3 is respectively provided on the front and rear sides of the support platform 2, and the clamping and fixing mechanism 3 includes a side plate 4, an electric push rod 6, an L-shaped plate 7, a first gear 12, a mounting seat 15, a drive motor 16, a second gear 17 and a clamping and fixing plate 18. The front and rear sides of the support platform 2 are respectively fixedly connected to the side plates 4, and the bottom surface of the side plate 4 is fixedly connected to the electric push rod 6, the L-shaped plate 7 is fixedly connected to the output end of the electric push rod 6, and the first gear 12 is movably connected to the outer wall of the L-shaped plate 7 through the rotating rod 13 on the inner wall, the outer wall of the L-shaped plate 7 is also fixedly connected to the mounting seat 15, and the outer wall of the mounting seat 15 is fixedly connected to the drive motor 16, the second gear 17 is fixedly connected to the output end of the drive motor 16 and meshes with the first gear 12, and the clamping and fixing plate 18 is movably connected to the rotating rod 13 through the threaded rod 20 on the outer wall and passes through the first gear 12.

[0022] like Figure 2 As shown, side panels 4 are fixedly mounted on the front and rear side walls of the support platform 2, and a group of symmetrical first guide holes 5 are opened on the top surface of the side panels 4. The first guide holes 5 on the side panels 4 are used to guide the movement of the L-shaped plate 7.

[0023] like Figure 2 As shown, the electric push rod 6 is fixedly mounted on the bottom surface of the side plate 4, and an L-shaped plate 7 is fixedly mounted on the top surface of the output end of the electric push rod 6. A first guide rod 8 is fixedly mounted on the bottom surface of the transverse portion of the L-shaped plate 7, and the first guide rod 8 is inserted into the first guide hole 5. When the output end of the electric push rod 6 drives the L-shaped plate 7 to move upward, the first guide rod 8 will move along the first guide hole 5. In this way, the clamping plate 18 can be moved to the center of the front and rear sides of the new energy battery according to the height of the new energy battery.

[0024] like Figure 3 As shown, a group of symmetrical second guide holes 9 are opened on the outer wall of the vertical portion of the L-shaped plate 7, and mounting holes 10 are further opened on the outer wall of the vertical portion of the L-shaped plate 7 and located between the second guide holes 9. Bearings 11 are fixedly installed in the holes of the mounting holes 10. The mounting seat 15 is fixedly installed on the outer wall of the vertical portion of the L-shaped plate 7. The second guide holes 9 opened on the L-shaped plate 7 are used to move the guide fibers for the clamping plate 18. The bearings 11 installed in the mounting holes 10 can enable the rotating rod 13 to achieve a rotation operation, and the mounting seat 15 is used to install the drive motor 16;

[0025] like Figure 3As shown, a rotating rod 13 is fixedly installed on the inner side wall of the first gear 12, and the rotating rod 13 and the bearing 11 are interlaced and fixed together. A threaded hole 14 that passes through the first gear 12 is also opened on the end wall of the rotating rod 13. The driving motor 16 is fixedly installed on the outer side wall of the mounting base 15, and a second gear 17 is fixedly installed on the output end of the driving motor 16. The second gear 17 and the first gear 12 are meshed with each other. After the driving motor 16 is turned on, the driving output end drives the second gear 17 to rotate. The second gear 17 drives the first gear 12 to rotate under the meshing action, so that the rotating rod 13 rotates in the bearing 11. During the rotation process, the rotating rod 13 can allow the threaded rod 20 to move through the threaded hole 14.

[0026] like Figure 3 As shown, a group of symmetrical second guide rods 19 are fixedly installed on the outer wall of the clamping plate 18, and the second guide rods 19 are inserted into the second guide holes 9. A threaded rod 20 is also fixedly installed on the outer wall of the clamping plate 18 and located between the second guide rods 19, and the threaded rod 20 is threadedly connected in the threaded hole 14. When the rotating rod 13 rotates, the threaded rod 20 will push the clamping plate 18 inward along the threaded hole 14, and the second guide rod 19 will move along the second guide hole 9 until the new energy battery is clamped and fixed between the front and rear symmetrical clamping plates 18, ensuring that the new energy battery will not slip or tilt and fall on the platform 2 when it is lifted, lowered or tilted by the lift body 1;

[0027] It should be noted that the present invention is a lift for replacing new energy batteries. When the new energy battery is placed on the top surface of the support platform 2, the electric push rod 6 installed on the bottom surface of the side panels 4 on the front and rear side walls of the support platform 2 is turned on. The electric push rod 6 will drive the output end to push the L-shaped plate 7 to move upward. During the movement, the first guide rod 8 installed on the bottom surface of the horizontal part of the L-shaped plate 7 will move in the first guide hole 5 opened on the top surface of the side panel 4 until the clamping fixing plate 18 on the rear end wall of the horizontal part of the L-shaped plate 7 is placed at the center of the front and rear sides of the new energy battery. Then the driving motor 16 installed on the outer wall of the mounting seat 15 is turned on. The driving motor 16 will drive the output end to drive the second gear 17 to rotate. During the rotation process, the second gear 17 is meshed with the first gear 12, so the second gear 17 will drive the first gear 12 to rotate. When the first gear 12 rotates, the rotating rod 13 installed on its inner side wall will engage the mounting hole 10 opened on the outer wall of the vertical part of the L-shaped plate 7. The first gear 12 is rotated in the bearing 11 installed inside. At the same time, because the threaded rod 20 installed on the outer wall of the clamping plate 18 is threadedly connected to the threaded hole 14 opened on the end wall of the rotating rod 13 and passing through the first gear 12, the threaded rod 20 will move inward along the threaded hole 14 and push the clamping plate 18 inward. The second guide rod 19 also installed on the outer wall of the clamping plate 18 will move in the second guide hole 9 to limit the movement of the clamping plate 18. The front and rear symmetrical clamping plates 18 will make relative movement operations until the new energy battery is clamped and fixed between the front and rear symmetrical clamping plates 18. By clamping and fixing the new energy battery, it can be ensured that the new energy battery will not slip or tilt and fall on the support platform 2 when it is lifted, lowered or tilted by the lift body, thereby preventing the new energy battery from being damaged after falling and improving the stability of the lift body 1 when the new energy battery is lifted and lowered.

[0028] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, various improvements may be made to the present invention and its components may be replaced with equivalents, or some of its technical features may be replaced with equivalents without departing from the scope of the present invention. Anything within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
