[0023] In the above-mentioned low-voltage mobile multi-purpose energy storage charging device, there are also a U-shaped plate 6, a first pull rope 7, a first permanent magnet 8, a rotating plate 9, a round rod 10 and a cooling fan 20; an air inlet 101 and an air outlet 102 are provided on the energy storage box 1, and the air inlet 101 and the air outlet 102 are arranged oppositely; three round rods 10 are bolted in the energy storage box 1; a U-shaped plate 6 is slidably connected to one side of the energy storage box 1 close to the air inlet 101, and the U-shaped plate 6 is made of iron; several rotating plates 9 are rotatably connected at the air inlet 101, and another rotating plate 9 is rotatably connected at the air outlet 102; two first pull ropes 7 are fixedly connected to the U-shaped plate 6, and several first thin ropes 71 are arranged on each first pull rope 7; each first thin rope 71 on the same first pull rope 7 is fixedly connected to the rotating plate 9 adjacent to the air inlet 101; the other end of each first pull rope 7 is fixedly connected to the rotating plate 9 at the air outlet 102; each first pull rope 7 contacts all the round rods 10, and the round rods 10 are used to limit the movement of the first pull rope 7 to ensure that the first pull rope 7 stably pulls the rotating plate 9 at the air outlet 102; two first permanent magnets 8 are fixedly connected in the energy storage box 1, and all the first permanent magnets 8 are opposite to the U-shaped plate 6; two cooling fans 20 are installed in the energy storage box 1, and all the cooling fans 20 are fixedly connected to each other.

[0024] A number of grooves are provided on one side of the powder packet 14 close to the battery packet 3, which are used to increase the gap between the powder packet 14 and the battery packet 3, enlarge the flow space of the air flow, and improve the heat dissipation effect.

[0025] The following is the working mode of the above-mentioned embodiment: When the present invention is needed to charge the vehicle, first, the pull rod 5 is manually pulled horizontally outward, and the pull rod 5 drives the connecting rod 11 and the U-shaped frame 12 to move outward synchronously. When the U-shaped frame 12 moves, it drives the connecting plate 15 and the extrusion block 16 to move outward synchronously, and the extrusion block 16 squeezes the square block 141 on the powder bag 14 until the extrusion block 16 completely covers the square block 141, forcing the powder bag 14 to expand and clamp the battery pack 3. When the connecting rod 11 moves outward, the fixing rod 111 on the connecting rod 11 gradually contacts the limit ring 4 and is forced to move downward by the limit ring 4. When the fixing rod 111 enters the interior of the limit ring 4 and is opposite to the fixing hole 41, the fixing rod 111 is reset and inserted into the fixing hole 41, thereby locking the connecting rod 11 and preventing the connecting rod 11 from moving and affecting the clamping stability of the powder bag 14 on the battery pack 3. Then, the present invention is manually pulled to the charging position by the pull rod 5 to charge the vehicle. Charging is carried out; in this way, it is different from the existing battery pack 3 which is fixed inside the equipment by bolts or quick-release structures. The present invention realizes the clamping of the battery pack 3 by the powder pack 14 by the pulling-out operation of the pull rod 5 during movement, that is, when the present invention is manually pulled to the charging position by the pull rod 5, the battery pack 3 is automatically fixed during movement. After the present invention is moved to the designated location, the fixing rod 111 can be pressed down manually, and the pull rod 5 can be pushed horizontally to reset, forcing the fixing rod 111 to disengage from the fixing hole 41, forcing the connecting rod 11, the U-shaped frame 12, the connecting plate 15 and the extrusion block 16 to reset, that is, the extrusion block 16 is away from the square block 141, and the powder pack 14 no longer clamps the battery pack 3. That is, during the charging process of the vehicle by the present invention, if there is a problem with the battery pack 3, the manual operation only needs to open the switch door on the energy storage box 1 to quickly replace and repair the battery pack 3 without manually disassembling the fixing structure of the battery pack 3.

[0026] It should be noted that when the pull rod 5 is manually pulled horizontally outward, the rotation point of the pull rod 5 and the connecting rod 11 will move to the outside of the limit ring 4, and the pull rod 5 can rotate freely up and down, making it convenient for manual pulling of the present invention through the pull rod 5.

[0027] It should be noted that the powder pack 14 does not contact the battery pack 3 when not under pressure.

[0028] During the charging process, since the battery pack 3 will independently dissipate heat, to prevent the battery pack 3 from overheating and affecting its service life and power supply rate, when the present invention moves to the charging position, first, an operator horizontally pulls the U-shaped plate 6 upward manually. The U-shaped plate 6 pulls the first pull rope 7 to move upward synchronously. The rotating plate 9 rotates into an inclined shape under the pulling of the first pull rope 7 and a number of first thin ropes 71, so that the rotating plate 9 no longer blocks the air inlet 101 and the air outlet 102. When the U-shaped plate 6 moves upward and contacts the first permanent magnet 8, the first permanent magnet 8 attracts and holds the U-shaped plate 6. Subsequently, the control of the cooling fan 20 is rotated, and the outside air enters the energy storage box 1 from the air inlet 101 and then is discharged from the air outlet 102, so that the outside air flows in the energy storage box 1 and takes away the heat dissipated by the battery pack 3, preventing the battery pack 3 from overheating and affecting its service life and power supply rate.

[0029] It should be noted that the present invention is not limited to charging vehicles. The present invention can also charge different electrical devices through the multi-interface module provided on the energy storage box 1, and the charging application range of the present invention is wide.

[0030] Embodiment 2 On the basis of Embodiment 1, with reference to Figure 2 、 Figure 4-Figure 7 and Figure 10-13As shown in the figure, a low-voltage mobile multi-purpose energy storage charging device. In the above-mentioned low-voltage mobile multi-purpose energy storage charging device, there are also a smoke sensor 17, an electric guide rail 18, a moving block 19, a third pull rope 21, a hook 22, a fixing plate 23, a cutting knife 24, a baffle 27 and a spring telescopic rod 28. The smoke sensor 17 is bolted inside the energy storage box 1. The electric guide rail 18 is bolted inside the energy storage box 1. The electric guide rail 18 is slidably connected with two moving blocks 19, and each moving block 19 is fixedly connected to the corresponding heat dissipation fan 20. A square groove 131 is formed on one side of each fixing frame 13 facing the placement frame 2. A hook 22 is arranged near the heat dissipation fan 20 in each square groove 131. A notch 132 is formed on each fixing frame 13, and the square groove 131 communicates with the corresponding notch 132. The powder packet 14 is located directly above the corresponding notch 132. A fixing plate 23 is slidably connected in each square groove 131. A plurality of cutting knives 24 are rotatably connected to the fixing plate 23. Each heat dissipation fan 20 is fixedly connected with a third pull rope 21, and each third pull rope 21 contacts the corresponding hook 22. Each third pull rope 21 is provided with a plurality of second thin ropes 211, and all the second thin ropes 211 on the same third pull rope 21 are fixedly connected to the corresponding cutting knife 24. A baffle 27 with the same number as the cutting knives 24 is fixedly connected to the fixing plate 23, and another baffle 27 is fixedly connected to the rotating shaft of each cutting knife 24. The baffle 27 fixedly connected to the fixing plate 23 is in a horizontal state, and the baffle 27 fixedly connected to the rotating shaft of the cutting knife 24 is in a vertical state, and the baffle 27 fixedly connected to the fixing plate 23 is located on the rotation path of the baffle 27 fixedly connected to the rotating shaft of the cutting knife 24. A spring telescopic rod 28 is fixedly connected inside the square groove 131, and the telescopic part of the spring telescopic rod 28 is fixedly connected to the fixing plate 23.

[0031] In the above-mentioned low-voltage mobile multi-purpose energy storage charging device, there are also an iron frame 25 and a second permanent magnet 26. An iron frame 25 is fixedly connected to each cutting knife 24. Second permanent magnets 26 with the same number as the iron frames 25 are fixedly connected to the inner bottom surface of the square groove 131. A torsion spring is arranged at the connection between each cutting knife 24 and the fixing plate 23.

[0032] In the above-mentioned low-voltage mobile multi-purpose energy storage charging device, there are also a top block 29 and a wedge block 30. The wedge block 30 is fixedly connected to the bottom of the U-shaped plate 6. The top block 29 is fixedly connected to the moving block 19.

[0033] The cross-section of the cutting knife 24 is V-shaped, which is used to open the cut of the powder packet 14 to facilitate the rapid outflow of the fire extinguishing powder.

[0034] A second diversion groove 241 is formed on the cutting knife 24, which is used to accelerate the outflow speed of the fire extinguishing powder.

[0035] The middle part of the iron frame 25 is hollowed out to avoid blocking the outflow of the fire extinguishing powder in the powder packet 14.

[0036] The working mode of the above embodiments is as follows: Considering that although the battery pack 3 is regularly maintained at present, it cannot be ensured that the battery pack 3 will not catch fire during use. If the battery pack 3 catches fire and is not handled, it will cause the battery pack 3 to explode and burn other parts of the present invention, resulting in excessive losses. Therefore, by setting a smoke sensor 17 in the energy storage box 1 to monitor the smoke change in the energy storage box 1 in real time, if the battery pack 3 catches fire and burns, the smoke generated after the battery pack 3 burns will be detected by the smoke sensor 17. After the smoke sensor 17 detects the smoke, it will issue an alarm and start an independent power supply to control the moving block 19 to drive the two cooling fans 20 to reciprocate back and forth along the electric guide rail 18. During this process, the cooling fan 20 pulls the third pull rope 21 to move synchronously. The third pull rope 21 pulls the cutting knife 24 to rotate upward through a plurality of second thin ropes 211. The rotating shaft of the cutting knife 24 rotates on the fixed plate 23, so that the cutting knife 24 is inserted into the powder bag 14. During the rotation of the cutting knife 24, the baffle 27 on its connecting shaft is driven to rotate synchronously until the baffle 27 on the rotating shaft of the cutting knife 24 is blocked by the baffle 27 on the fixed plate 23 and then stops, as Figure 13 shown. At this time, the cutting knife 24 cannot continue to rotate. The third pull rope 21 drives the cutting knife 24, the baffle 27 and the fixed plate 23 to move leftward synchronously through a plurality of second thin ropes 211. When the fixed plate 23 moves leftward, it squeezes the telescopic end of the spring telescopic rod 28. When the cutting knife 24 moves leftward, it cuts the bottom of the powder bag 14, so that the fire extinguishing powder in the powder bag 14 flows out from the cut and falls into the square groove 131 through the notch 132. Then, the wind blown by the cooling fan 20 blows and raises the fire extinguishing powder in the square groove 131, so that the fire extinguishing powder is dispersed in the energy storage box 1, covers the surface of the battery pack 3, and conducts fire extinguishing work, avoiding the continuous burning of the battery pack 3 and avoiding burning other parts of the present invention, resulting in excessive losses; in the present invention, the powder bag 14 used to fix the battery pack 3 is also used for fire extinguishing. Different from the prior art, there is no need to set an additional fire extinguishing powder storage structure, and the structure is ingenious; it should be noted that the square groove 131 is directly opposite to the air flow blown by the cooling fan 20, and by making the fire extinguishing powder in the powder bag 14 fall into the square groove 131, different from the prior art, it can avoid the problem that a large amount of fire extinguishing powder falls to the bottom of the energy storage box 1, resulting in less fire extinguishing powder participating in the fire extinguishing and affecting the fire extinguishing effect.

[0037] It should be noted that after the fire extinguishing powder leaks out of the powder bag 14, the powder bag 14 is in a shriveled state, does not fit with the battery pack 3, and there is a gap between the fixing frame 13 and the battery pack 3, which will not block the full contact between the fire extinguishing powder and the battery pack 3.

[0038] Taking into account that when the cutting knife 24 cuts the powder bag 14, the fire extinguishing powder at the cut of the powder bag 14 accumulates, resulting in the fire extinguishing powder not being able to flow out quickly, affecting the fire extinguishing efficiency, therefore, by setting the cross-section of the cutting knife 24 to be V-shaped, the cutting knife 24 can open the cut of the powder bag 14, avoiding the problem of the fire extinguishing powder at the cut of the powder bag 14 accumulating, resulting in the fire extinguishing powder not being able to flow out quickly, affecting the fire extinguishing efficiency, and by providing a second guide groove 241 on the cutting knife 24, when the cutting knife 24 is inserted into the powder bag 14, the interior of the powder bag 14 is connected to the outside through the second guide groove 241, and the fire extinguishing powder in the powder bag 14 can be discharged through the guide groove 241. The powder flows out from groove 241 into the square groove 131, further accelerating the outflow speed of the fire extinguishing powder and improving the fire extinguishing efficiency. It should be noted that when the moving block 19 drives the cooling fan 20 to move back and forth, when the cooling fan 20 gradually moves to the initial position, the pull rope 3 21 gradually loses its tension, thereby releasing the tension on the fixed plate 23, so that the spring telescopic rod 28 pushes the fixed plate 23 to move and reset. During the movement and reset process of the fixed plate 23, the fire extinguishing powder in the square groove 131 will be pushed, so that the accumulated fire extinguishing powder will be dispersed, which is conducive to the fire extinguishing powder being blown by the cooling fan 20, and the fire extinguishing powder will be prevented from being blocked in the square groove 131, affecting the fire extinguishing operation.

[0039] Furthermore, by setting a torsion spring at the connection between the fixing plate 23 and the cutting blade 24, in the initial state, Figure 12 As shown, the cutting knife 24 is fixed to the permanent magnet 26 by the iron frame 25. At this time, the torsion spring at the connection between the fixed plate 23 and the cutting knife 24 is in a compressed state. When the cutting knife 24 is pulled upward by a number of thin ropes 211, the cutting knife 24 pulls the iron frame 25 away from the permanent magnet 26. At this time, the torsion spring at the connection between the fixed plate 23 and the cutting knife 24 releases the pressure, forcing the cutting knife 24 to remain in a relatively vertical state, to avoid the cutting knife 24 being reset by the flow of the fire extinguishing powder when the pull rope 3 21 gradually loses its tension, so that the cutting knife 24 is always inserted into the powder bag 14, ensuring the guiding effect of the cutting knife 24 on the fire extinguishing powder. It should be noted that after the fire extinguishing is completed, when the battery pack 3 is manually removed and the powder bag 14 is replaced, the cutting knife 24 is manually pressed downward so that the cutting knife 24 drives the iron frame 25 to contact the permanent magnet 26.

[0040] It is also considered that during the fire extinguishing process, the fire extinguishing powder will be blown out of the energy storage box 1 through the air inlet 101 and the air outlet 102, affecting the fire extinguishing effect. Therefore, when the moving block 19 drives the cooling fan 20 to move back and forth, the moving block 19 will drive the top block 29 to move synchronously. During the movement of the top block 29, it will squeeze the wedge block 30 downward. The wedge block 30 drives the U-shaped plate 6 to disengage from the first permanent magnet 8 downward. At this time, the rotating plate 9 loses the restriction of the first pulling rope 7 and the first thin rope 71, rotates from the inclined state to the vertical state, and closes the air inlet 101 and the air outlet 102, avoiding the fire extinguishing powder from being blown out of the energy storage box 1 through the air inlet 101 and the air outlet 102, which affects the fire extinguishing effect.
