DETAILED DESCRIPTION

[0019] Currently, mobile charging piles on the market are equipped with fixed-capacity battery packs, so the charging capacity of a mobile device is also fixed. In actual application scenarios, the demand for discharge capacity varies depending on the scenario. Especially in places with obvious tidal phenomena, charging piles need to be equipped with large-capacity batteries during peak hours to cope with huge charging needs; conversely, only small-capacity batteries are needed to meet charging needs, so it is necessary to effectively allocate battery packs.

[0025] like Fig.10 and 11 As shown, the protective mechanism 200 includes a gravity ball 202, a connecting plate 203 and a plurality of inflatable frames 201. The inflatable frames 201 are fixedly connected to the surface of the battery pack 6. The front and rear sides of the connecting plate 3 are fixedly connected to the controller 208.

The wedge-shaped block 209 moves in the inside of the controller 208 through the elastic block. The lower end of the drive shaft 207 is provided with a contact 210 in the middle of the controller 208.

[0026] like Fig.10 and 11 As shown, four groups of leveling blocks 206 are fixedly connected inside the connecting plate 203, the upper end of the gravity ball 202 is fixedly connected to the connecting part 204, the surface of the connecting part 204 is fixedly connected to the wedge-shaped disk 205, the wedge-shaped disk 205 is slidably connected to the surface of the leveling block 206, the upper end of the connecting part 204 is movably connected to the lower end of the base plate 1 through a ball joint, and the lower end of the connecting plate 203 is fixedly connected to the connecting plate 3 through a spring block.

[0027] like Fig.12 and 13As shown, the cleaning mechanism 300 includes a connecting shaft 301, which is rotatably connected to the surface of the connecting plate 3; the front and rear ends of the connecting shaft 301 are fixedly connected to the right moving wheel 5, the front and rear sides of the surface of the connecting shaft 301 are fixedly connected to the inclined plate 302, the surface of the inclined plate 302 is movably connected to the inclined rod 303, the inclined rod 303 and the inclined plate 302 are vertically arranged, the front and rear sides of the inclined rod 303 are fixedly connected to the connecting rod 304, the upper end surface of the connecting rod 304 is fixedly connected to the matching block 305, the upper end surface of the matching block 305 is fixedly connected to the limiting sleeve 306, the lower end surface of the bottom plate 1 is fixedly connected to the limiting rod 307, the limiting sleeve 306 is slidably connected to the surface of the limiting rod 307, the surface of the limiting sleeve 306 is fixedly connected to the fixing plate 308, and the lower end of the fixing plate 308 is provided with a cleaning brush 309; the front and rear side inclined plates 302 are symmetrically arranged front and back along the midpoint of the connecting shaft 301.

[0028] When the stacking device is moving, the right moving wheel 5 drives the connecting shaft 301 to rotate, and the connecting shaft 301 drives the swash plate 302 to rotate. Since the swash plate 302 is inclined, the swash plate 302 drives the slanted rod 303 movably connected thereto to reciprocate back and forth, the slanted rod 303 drives the connecting rod 304 to reciprocate back and forth, the connecting rod 304 drives the matching block 305 to reciprocate back and forth, the matching block 305 drives the limiting sleeve 306 to reciprocate back and forth, the limiting sleeve 306 drives the fixing plate 308 to reciprocate back and forth, and the fixing plate 308 drives the cleaning brush 309 to reciprocate back and forth, so that the cleaning brush 309 cleans the debris on the ground.

[0029] Furthermore, left movable wheels 4 are provided on the front and rear sides of the connecting plate 3, a push rod 2 is fixedly connected to the left side of the upper end surface of the bottom plate 1, a plurality of radiators 9 are detachably connected to the surface of the battery pack 6, and an inflatable airbag is provided on the upper end of the battery pack 6.

[0030] When the battery packs 6 are stacked, the locking block 101 is locked with the latch 102 in cooperation with the driven wedge block 106 and the double-sided arc-shaped slider 105, thereby limiting the stacked battery packs 6; the pressure on the double-sided arc-shaped slider 105 is increased by contracting the airbags between the upper and lower battery packs 6, so that the double-sided arc-shaped slider 105 releases the limiting work on the driven wedge block 106.

[0031] like Figure 6 As shown, the top of the battery pack 6 has a female connector for power supply, and a plurality of positioning holes are arranged around it. The bottom of the battery pack 6 has a male connector for power supply, and the male connector and the female connector are respectively equipped with high-voltage and low-voltage connectors. When the male connector is inserted into the female connector, the connectors will be connected one by one, realizing the connection of the circuit and the connection of the communication signal line.

[0032] The stacking between the charging pile module 8 and the battery pack 6: Its principle is similar to that between the battery packs 6. The charging pile module 8 is a module with external discharge capability. It is located at the top layer of the entire structural system. When the male connector 7 of the charging pile module 8 is inserted into the female connector of the lower battery pack 6, and the cylinder is inserted into the positioning hole, a tight stacking between the charging pile module 8 and the battery pack 6 is formed, and the circuits and communication signal lines therein are also connected.

[0033] Stacking of battery pack 6 and mounting platform 12: The principle is similar to the stacking between battery packs 6. The male connector 7 of the upper battery pack 6 is inserted into the female connector 7 of the mounting platform 12, and the cylinder is inserted into the positioning hole on the surface of the mounting platform 12 to form a tight stack of the battery pack 6 and the mounting platform 12, and the circuits and communication lines therein are also connected respectively.

[0034] Working principle: Place the battery pack 6 to be powered on the bottom plate 1 so that the middle of the lock block 101 is located directly above the latch 102. When the lock block 101 at the lower end of the battery pack 6 is sleeved on the latch 102 at the upper end of the mounting platform 12, the driven wedge block 106 moves to the middle of the lock block 101 under the elastic force of the return spring 108. When the inclined surface of the driven wedge block 106 contacts the arc surface of the upper end of the upper protrusion 104, the inclined surface of the driven wedge block 106 moves to the left side of the inside of the lock block 101 under the pressure of the arc surface of the driven wedge block 106. When the upper protrusion 104 completely releases the pressure applied to the driven wedge block 106, the driven wedge block 106 moves to the right between the upper protrusion 104 and the double-sided arc slider 105 under the elastic force of the return spring 108. At this time, the battery is no longer subjected to additional pressure when the airbag is filled. The upper and lower layers of multiple battery groups can be stacked by locking the locking block 101 and the latch 102; if the stacking device topples over, at the moment of tilting, the gravity ball 202 swings under its own gravity, so that the gravity ball 202 drives the connecting part 204 to always be located on the plumb line, and the connecting part 204 drives the wedge-shaped disc 205 fixedly connected thereto to swing, and the wedge-shaped disc 205 exerts pressure on the leveling block 206 while swinging, but because the connecting disc 203 is connected to the connecting plate 3, the leveling block 206 will only drive the connecting disc 203 to move downward along the slide groove of the connecting plate 3 after being pressurized, and the connecting disc 203 drives the driving shaft 207 fixedly connected thereto to move downward, and the driving shaft 207 exerts pressure on the contact 210 when moving downward, and the contact 210 is squeezed to open the control switch, and the contact 210 controls the inflatable frame 201 to inflate the airbag, so that the protective mechanism 200 performs emergency protection on the toppled battery in the first time; When the stacking device is moving, the right moving wheel 5 drives the connecting shaft 301 fixedly connected thereto to rotate, and the connecting shaft 301 drives the slanted plate 302 fixedly connected thereto to rotate. Since the slanted plate 302 is inclined, the slanted plate 302 drives the slanted rod 303 movably connected thereto to reciprocate back and forth, and the slanted rod 303 drives the connecting rod 304 fixedly connected thereto to reciprocate back and forth, and the connecting rod 304 drives the matching block 305 fixedly connected thereto to reciprocate back and forth, and the matching block 305 drives the limiting sleeve 306 fixedly connected thereto to reciprocate back and forth, and the limiting sleeve 306 drives the fixed plate 308 fixedly connected thereto to reciprocate back and forth, and the fixed plate 308 drives the cleaning brush 309 fixedly connected thereto to reciprocate back and forth, so that the cleaning brush 309 cleans the debris on the ground; If the battery pack 6 needs to be removed, the airbag on the surface of the battery pack 6 is deflated to increase the pressure exerted by the upper battery pack 6 on the lower battery pack 6. The driven wedge block 106 moves to the left under the pressure exerted by the double-sided arc-shaped slider 105, and then the locking work between the lock block 101 and the latch 102 is released under the upper arc surface of the lower protrusion 103.

[0035] While embodiments of the present invention have been shown and described, those skilled in the art will appreciate that numerous changes, modifications, substitutions and variations may be made to the embodiments without departing from the spirit and scope of the present invention, the scope of which is defined by the claims and their equivalents.
