[0117] The frame 20 includes a main frame 201 and an extension frame 202 protruding from the top side of the main frame 201. The battery swapping station and the connection station are horizontally spaced and respectively located in the extension frame 202 and the main frame 201. The clean water injection device 50 is located at the bottom of the extension frame 202 and is used to connect with the water inlet 114 at the top of the main frame 11 of the split cleaning vehicle below the battery swapping station. This allows clean water to be injected into the water inlet 114 through the water inlet channel (not shown in the figure) inside the frame 20, and then supplied to the cleaning module 41 through the water supply pipeline inside the main frame 11. This enables the battery swapping station 10 to automatically swap batteries with the split cleaning vehicles while automatically injecting water.

[0118] Please refer to the following: Figure 5-6 8. As a preferred embodiment of this invention, the side end of the main frame 11 of the vehicle body is provided with a drain outlet (not shown in the figure) that connects to the return water pipe.

[0119] The sewage discharge device 60 is located on the side of the main frame 201 facing the extension frame 202 (i.e. facing the battery swapping station). It is used to connect with the drain outlet on the side of the main frame 11 of the split cleaning vehicle that arrives below the battery swapping station, so that the ground sewage is discharged into the drainage water channel inside the frame 20 through the water absorption module 42, the return water pipe inside the main frame 11 (not shown in the figure) and the drain outlet, so as to realize the automatic sewage / drainage of the 10 pairs of split cleaning vehicles in the battery swapping station while automatically swapping batteries.

After being fully charged by the charging device, it is moved by the battery 5 transfer device (not shown in the figure) into the battery compartment (not shown in the figure) located inside the main frame 11 of the vehicle body for storage. At the same time, another fully charged battery 5 is directly moved from the battery compartment into the split cleaning vehicle for replacement and installation via the battery 5 loading device (not shown in the figure).

[0121] Please refer to the following: Figure 5-13 In this embodiment, the battery swapping station 10 further includes:

[0122] The frame positioning device 70 is located on the frame 20 and is used to dock the split cleaning vehicle and position the split cleaning vehicle below the battery swapping station.

[0123] Please refer to the following: Figure 5-13 As a preferred embodiment of this example, the frame positioning device 70 includes a tensioning positioning mechanism. The tensioning positioning mechanism consists of a mounting sheet metal, a drive cylinder mounted on the mounting sheet metal, and a positioning clamping plate driven by the drive cylinder. The drive cylinder is used to drive the positioning clamping plate to move in a translational and telescopic motion relative to the split-type cleaning vehicle, so that the positioning clamping plate locks or disengages from the split-type cleaning vehicle, thereby positioning or unlocking the split-type cleaning vehicle below the battery swapping station.

[0124] The working principle of the split-type cleaning vehicle and the battery swapping system of the cleaning vehicle using the same provided by this utility model is as follows:

[0125] The automated guided vehicle 2 automatically drives into the bottom of the main frame 11 of the cleaning vehicle frame 1. The lifting mechanism 31 of the lifting device 3 on the top of the automated guided vehicle 2 drives the lifting top seat 32 to lift into place. After the locking mechanism drives the positioning pin to connect with the positioning hole at the bottom of the main frame 11, the lifting mechanism 31 continues to lift the cleaning vehicle frame 1 to lift it off the ground, and pulls the cleaning vehicle frame 1 to move forward, backward, left and right and to turn freely in 360 degrees.

[0126] As the automated guided vehicle 2 begins to move horizontally and turn, the water supply pump of the water supply device 7 draws clean water from the water tank 71 and delivers the clean water through the water supply pipeline to the cleaning brush 412 of the cleaning module 41. The cleaning brush 412 and the water suction module 42 are lowered relative to the cleaning vehicle frame 1 by manual pedaling or by the brush lifting device 411 until they are close to the ground. The rotation drive device drives the rotating brush to complete the rotational rinsing action, so as to perform a rotational cleaning operation on the ground along the movement trajectory of the automated guided vehicle 2. The return water pump of the sewage recovery device 8 evacuates the air inside the sewage tank 81 to form a negative pressure, so that the sewage collected by the water suction module 42 along the movement trajectory of the automated guided vehicle 2 flows into the sewage tank 81 from the return water pipeline and is stored in the sewage tank 81, so that the automated guided vehicle 2 pulls the cleaning device 4 on the cleaning vehicle frame 1 to perform a cleaning operation on the ground.

[0127] When the battery 5 of the split-type cleaning vehicle needs to be swapped or charged, the automatic guide vehicle 2 moves the cleaning vehicle frame 1 to the battery swapping station 10. After arriving at the battery swapping station 10, the split-type cleaning vehicle is positioned below the battery swapping station by docking with the frame positioning device 70. Then, the control device controls the opening and closing door 6 to automatically open and close the top of the internal space of the main frame 11. The translation drive device 30 drives the picking and placing unit 301 to move horizontally to the battery swapping station, so that the picking and placing unit 301 can automatically pick up and remove the battery 5 located on the upper side of the internal space of the main frame 11 through the open opening and closing door 6. Next, the translation drive device 30 drives the picking and placing unit 301 to move horizontally from the battery swapping station to the connecting station. The lifting drive device 40 drives the loading platform to move vertically upward to below the connecting station, so that the loading platform can receive the battery 5 transferred by the picking and placing unit 301 that has arrived at the connecting station. Subsequently, the lifting drive device 40 drives the material platform to descend vertically from below the connecting station to the charging station, where the charging device performs a charging operation on the battery 5 that has arrived at the charging station. The step of reinstalling the fully charged battery 5 on the top of the internal space of the main frame 11 is the reverse of the battery 5 removal process described above. Alternatively, another fully charged battery 5 can be directly moved from the battery compartment into the split-type cleaning vehicle for replacement installation using the battery 5 loading device.

[0128] When the split-type cleaning truck needs to separate the automatic guide vehicle 2, the lifting mechanism 31 descends to help the cleaning truck frame 1 be supported on the ground again. The locking mechanism drives the positioning pin to disengage from the positioning hole at the bottom of the main frame 11 to unlock the automatic guide vehicle 2. The lifting mechanism 31 continues to drive the lifting top seat 32 to descend until it is reset. The automatic guide vehicle 2 automatically travels away from the bottom of the main frame 11, completing the separation of the automatic guide vehicle 2 from the cleaning truck frame 1.

[0129] When the cleaning vehicle frame 1, which is separated from the automatic guide vehicle 2, needs to be manually pushed, the cleaning brush 412 and the water suction module 42 can be automatically driven by the operator to rise relative to the cleaning vehicle frame 1 until they are off the ground. At this time, the operator can push the cleaning vehicle frame 1 to move horizontally or rotate freely under the action of the wheels 13.

[0130] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
