Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0022] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] The following is combined with Figures 1-4 This utility model will be described in detail.

[0024] Example A lifting mechanism for a battery swapping device includes at least two spaced-apart support frames 1, with a lifting frame 8 positioned between the two support frames 1. A guide rail 23 is vertically mounted on the support frame 1, and the lifting frame 8 is equipped with a first lifting guide wheel 20, a second lifting guide wheel 21, and a third lifting guide wheel 24 that cooperate with the guide rail 23. The first lifting guide wheel 20 and the third lifting guide wheel 24 are clamped on both sides of the guide rail 23, and the second lifting guide wheel 21 is in contact with the end face of the guide rail 23.

[0025] The lifting frame 8 can move vertically, and the second lifting guide wheel 21 rolls and adheres to the side of the guide rail 23 away from the support frame 1. Figure 2 and 3 As shown, the first lifting guide wheel 20, the second lifting guide wheel 21 and the third lifting guide wheel 24 abut against the three side walls of the guide rail 23 to limit the movement, ensuring the stability of the lifting frame 8, and reducing the wear between the guide rail 23 and the guide wheel by rolling.

[0026] A transmission device for driving the lifting frame 8 to rise and fall is installed on the support frame 1. The transmission device includes a first driving sprocket 22 and a first driven sprocket 3 that are rotatably arranged at intervals. A lifting chain 2 is meshed on the first driving sprocket 22 and the first driven sprocket 3. A connecting seat 19 that is fixedly connected to the lifting frame 8 is provided on the lifting chain 2. The first driving sprocket 22 is connected to a drive shaft 11, the drive shaft 11 is connected to a reducer 12, and the reducer 12 is connected to a lifting motor 13. The lifting motor 13 rotates the drive shaft 11 through the reducer 12, thereby driving the lifting chain 2 to move the lifting frame 8 up and down in the vertical direction. The transmission device can also use a screw-driven lifting structure.

[0027] A traveling wheel 4 is rotatably mounted on the lower end of the support frame 1. A track 5 is mounted below the traveling wheel 4. A second driven sprocket is fixedly connected to the traveling wheel 4. A second driving sprocket 18 is rotatably mounted on the support frame 1. A traveling chain 17 is meshed on the second driving sprocket 18 and the second driven sprocket. A traveling motor 16 is connected to the second driving sprocket 18. The traveling motor 16 drives the second driving sprocket 18 to rotate, which, in conjunction with the traveling chain 17, drives the second driven sprocket and the traveling wheel 4 to rotate synchronously, thereby realizing the movement of the lifting mechanism.

[0028] A first reinforcing rod 14 located at the lower end of the support frame 1 connects the two support frames 1. A sliding limit seat 6, which is slidably engaged with the track 5, is fixedly connected to the first reinforcing rod 14. The track 5 is I-shaped. When the lifting mechanism moves along the stationary track 5, the sliding limit seat 6 always maintains a sliding engagement with the track 5. The sliding limit seat 6 is equipped with an inwardly curved hook structure, which, in conjunction with the I-shaped track 5, prevents the lifting mechanism from derailing or overturning during movement. The first reinforcing rod 14 connects the two support frames 1 into a whole and strengthens the structure.

[0029] The upper surface and both end faces of the first reinforcing rod 14 are provided with buffer elastic blocks 15. The buffer elastic blocks 15 can buffer the impact force when the lifting frame 8 descends and the impact force when the support frame 1 moves with other structures, so as to avoid damage to the relevant structures due to impact.

[0030] The lifting frame 8 is detachably connected to a second reinforcing rod 7 perpendicular to the two support frames 1. The second reinforcing rod 7 can enhance the structural strength of the lifting frame 8. The second reinforcing rod 7 is only used during the entire lifting mechanism transportation process. When performing subsequent battery swapping operations, the second reinforcing rod 7 needs to be removed to avoid the second reinforcing rod 7 affecting the hoisting of the battery 100.

[0031] A battery swapping device uses a lifting mechanism. The device includes a telescopic arm 25 mounted on the upper end of a lifting frame 8, with a lifting device 26 installed at the telescopic end of the telescopic arm 25. After the lifting frame 8 is raised or lowered, it drives the telescopic arm 25 to adjust its height position. After the lifting device 26 fixes the battery 100, the position of the battery 100 is adjusted by the raising and lowering and moving of the lifting mechanism and the telescopic arm 25, thereby installing the battery 100.

[0032] The fixed end of the telescopic arm 25 is rotatably connected to the lifting frame 8. The lifting frame 8 is equipped with a swing telescopic rod 10. One end of the swing telescopic rod 10 is hinged to the fixed end of the telescopic arm 25, and the other end of the swing telescopic rod 10 is hinged to the lifting frame 8. The swing telescopic rod 10 controls the overall small-angle horizontal swing of the telescopic arm 25 through telescopic control, thereby better adapting to the installation requirements of the battery 100.

[0033] The lifting frame 8 is provided with an arc-shaped guide groove 9, and a roller 27 that rolls with the arc-shaped guide groove 9 is rotatably mounted on the fixed end of the telescopic arm 25. During the swinging process, the telescopic arm 25 achieves stable swinging through the roller 27 and the arc-shaped guide groove 9, and also reduces the load at the rotating connection of the telescopic arm 25.

[0034] The maximum lifting height of the lifting frame 8 over the telescopic boom 25 is no less than twice the height of the battery 100. After the telescopic boom 25 lifts the battery 100, it needs to cross over other placed batteries 100. To avoid the placed batteries 100 affecting the movement of the battery swapping equipment, the maximum lifting height of the lifting frame 8 is set to be more than twice the height of the battery 100. At this time, the lifted battery 100 moves above the placed batteries 100. To facilitate the support frame 1 crossing over the placed batteries 100 during movement, the support frame 1 is set as a portal frame with a passageway.

[0035] The specific structural features of the telescopic boom 25, lifting device 26, arc-shaped guide groove 9 and roller 27 can be found in the utility model patent with publication number CN220220693U, and will not be elaborated here.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
