In the present embodiment, the first track 211 extends along the length of the chassis 21 to facilitate movement of the battery swapping device 13. The battery swapping device 13 is movably connected to the first track 211, for example by a slider structure, rollers, or a nut-screw mechanism, such that the battery swapping device 13 can move back and forth along the first track 211. In some embodiments, the battery swapping device 13 can also be provided with a driving mechanism, for example a motor, a pneumatic cylinder, or other power components, to drive the battery swapping device 13 to move along the first track 211.

[0037] FIG. 3 is a schematic diagram of the structure of the battery swapping device 13 when it is suspended from the second track 111. As shown, similar to the first frame 212, the second frame 112 includes one or more vertical columns, the bottom of which is provided at the four corners of the chassis 11, and the second track 111 is connected to the top of the columns. FIG. 3 To facilitate the docking of the first track 211 and the second track 111, the docking end of the second track 111 is at the same height as the docking end of the first track 211, and in some preferred embodiments, the first track 211 and the second track 111 extend horizontally and are at the same height, such that when the chassis 11 is docked to the chassis 21, the first track 211 is docked to the second track 111, and the battery swapping device 13 moves along the first track 211 or the second track 111, i.e. between the first track 211 and the second track 111. Similarly, the battery swapping device 13 can also be movably connected to the second track 111 by a slider structure, rollers, or a nut-screw mechanism, which will not be described here.

[0038] FIG. 4 is a schematic diagram of the structure of the battery swapping device 13. As shown, FIG. 4As shown, the battery replacing device 13 includes a rack 131 and a mechanical arm, the rack 131 is movably connected to the first track 211. The mechanical arm includes a telescopic mechanism 132, a telescopic member 134 and a hanging member 133, the telescopic mechanism 132 is connected to the rack 131 and can be telescoped in the horizontal direction relative to the rack 131. Specifically, the telescopic mechanism 132 can include a cylinder, a lead screw, a slider and a guide rail mechanism, etc., which can realize the function of extending or retracting relative to the rack 131, but those skilled in the art can still use other conventional technical means in the art to realize the telescoping action. The hanging member 133 is movably connected to the telescopic mechanism 132 in the vertical direction, and can move up and down in the vertical direction to dock the battery box 40. In some embodiments, the telescopic member 134 is one or a combination of a hydraulic cylinder, a pneumatic cylinder or a lead screw mechanism, for example, in FIG. 3 and FIG. 4 In the embodiment shown, the telescopic member 134 includes a lead screw mechanism, the hanging member 133 is connected to the nut of the lead screw mechanism, and the screw rod of the lead screw mechanism is connected to the telescopic mechanism by a motor, so that the motor can drive the screw rod to rotate, and the hanging member 133 is moved up and down in the vertical direction by the nut. In this embodiment, the bottom of the hanging member 133 is hook-shaped, which is used to follow the telescopic mechanism 132 to move in the vertical direction and to telescope in the horizontal direction to hook the cross beam of the battery box 40, and to complete the docking action of the battery box 40. When it is necessary to move the battery box 40, the rack 131 is first moved to the appropriate position along the first track 211, and then the telescopic mechanism 132 is extended until the hanging member 133 corresponds to the cross beam of the battery box 40, and at the same time the telescopic member 134 is actuated to move the hanging member 133 in the vertical direction.

[0039] Finally, the telescopic mechanism 132 and the telescopic member 134 are moved in cooperation until the hanging member 133 is located below the cross beam of the battery box 40, realizing the docking of the battery box 40, so that the battery box 40 can be moved in the width direction of the chassis 21.

[0040] In addition, preferably, in order to prevent the docking error between the first track 211 and the second track 111 during the movement of the battery replacing device 13, the hoisting type mobile battery replacing system can further comprise a locking mechanism (not shown in the figure) for locking the first track 211 and the second track 111 when the chassis 11 is docked with the base plate 21. For example, the locking mechanism can comprise a plug and a socket respectively arranged on the first track 211 and the second track 111, and the plug is inserted into the socket by a motor to achieve the docking and fixing of the first track 211 and the second track 111. In other embodiments, the locking mechanism can also be a clamping piece for clamping and fixing the base plate 21 and the chassis 11, and those skilled in the art can also use other structures to fix the base plate 21 and the chassis 11 to achieve the fixed docking of the first track 211 and the second track 111, which is not limited in the present application.

[0041] In use, the first vehicle body 20 pulls the one or more battery boxes 40 through the base plate 21 to a predetermined location, and then the second vehicle body 10 pulls the chassis 11 carrying the battery replacing device 13 to a position corresponding to the first vehicle body 20 and the base plate 21, and makes the first track 211 dock with the second track 111.

[0042] The battery replacing device 13 moves to the first track 211 through the second track 111 and is located above the battery box 40. After the vehicle 30 to be replaced is moved to either side of the base plate 21, the battery replacing device 13 moves to a suitable position on the first track 211, and the telescopic mechanism 132 and the suspension piece 133 of the mechanical arm are telescoped in the width direction of the base plate 21, so that the battery box 40 of the vehicle 30 can be replaced.

[0043] The hoisting type mobile battery replacing system described above can realize the on-vehicle battery replacing operation by installing the battery box 40 on the base plate 21 and arranging the first track 211 on the base plate 21, so that the battery replacing device 13 can be movably suspended on the first track 211 and can move above the battery box 40 to move the battery box 40. This not only solves the problems of large occupation area and the need for infrastructure of the fixed charging station, but also facilitates the migration of the hoisting type mobile battery replacing system, reduces the equipment cost of the system, and improves the flexibility of the equipment. After the replacement of the battery box 40 on the base plate 21 is completed, the battery replacing device 13 can return to the second track 111, and the first vehicle body 20 pulls the base plate 21 to drive it away. At the same time, the second vehicle body 10 can pull the chassis 11 to move to dock with a new base plate 21 to continue the battery replacing operation, so as to improve the use efficiency of the battery replacing device 13.
