[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) This photovoltaic energy storage charging device, by setting a first pushing mechanism, etc., when a high current charging scenario is required, the first moving component is started to move the pushing block in the direction close to the first moving plate. At this time, the first inclined surface abuts against the side wall of the first moving plate, thereby pushing the two first mounting plates to move downward. At the same time, the first spring is compressed. When the first conductive strip abuts against the top of the movable plate, the conductive column is pushed downward. At the same time, the first spring is stretched, and the lower end of the conductive column is connected to the positive pole and the negative pole of each battery respectively. At this time, the positive poles of multiple batteries can be connected to the positive pole through the conductive pole, the movable plate, the first conductive strip, the conductive wire and the first terminal. Similarly, the negative poles of multiple batteries can be connected to the negative pole through the second terminal, etc., so as to realize parallel connection of multiple batteries, which can improve the current output capacity, enhance the power supply capacity and stability. When a high voltage charging scenario is required, the first moving component The pushing block moves in the direction close to the second mounting plate. At this time, the first moving plate can move upward and reset under the action of the first spring, and drive the two first mounting plates to move upward and reset. At the same time, the moving disk and the conductive column can move upward and reset under the action of the third spring. When the second inclined surface abuts against the side wall of the second mounting plate, it can push it to move downward. At the same time, the second spring is stretched. At this time, the second terminal and the first terminal abut against the top of the moving disk at the two diagonals, thereby pushing the conductive column to move downward. At the same time, the third spring is compressed, and the lower end of the conductive column is respectively connected to the positive electrode column and the negative electrode column of each battery, and the second conductive strip connects the positive and negative electrodes of two adjacent batteries, which can realize the series connection of multiple batteries and provide a higher output voltage, so that according to different charging scenarios, it is convenient to adjust multiple batteries for parallel or series connection, which is more convenient and quick to use and makes the charging effect better.

[0017] (2) This photovoltaic energy storage charging device is provided with a circulation mechanism, etc., so that when the battery needs to be cooled during use, the fan is started to perform exhaust operation, so that the external air enters through the heat exchange hole on one side and is discharged after passing through the fixed box and the air outlet pipe. At the same time, when passing through the annular cover, the internal coolant can cool the incoming air, thereby making the cooling efficiency of the battery higher and the effect better. At the same time, when the air enters the fixed box, it impacts the surface of the rotating fan to rotate, and drives the rotating shaft and the rotating disk to rotate. When the protrusion abuts against the side wall of the fixed block, it pushes the L-shaped plate to move upward, and drives the piston to move upward. At the same time, the fourth spring is compressed.

[0018] (3) This photovoltaic energy storage charging device, by setting a sealing mechanism, etc., starts the second moving component in a low temperature state, drives the second moving plate to move downward, and at the same time, drives the sealing plate to move downward synchronously and seal the heat exchange hole, thereby ensuring the sealing state of the battery box and being able to keep the battery warm. At the same time, when the second moving plate moves downward, the piston is pulled upward by the pull rope, so that the coolant in the heat exchange hole can be completely drawn into the cooling box for temporary storage, and a vacuum state is formed in the heat exchange hole, so that the insulation effect of the battery is better, thereby ensuring its use effect and life. In addition, when the temperature sensor detects that the temperature in the battery box is high, it can also dissipate the heat inside it appropriately. BRIEF DESCRIPTION OF THE DRAWINGS

When the second inclined surface 504 abuts against the side wall of the second mounting plate 25, it can push it to move downward. At the same time, the second spring 303 is stretched. At this time, the second terminal 23 and the first terminal 2 4 abuts against the top of the moving disk 28 at the two diagonal positions, thereby pushing the conductive column 29 to move downward. At the same time, the third spring 403 is compressed, and the lower end of the conductive column 29 is respectively connected to the positive column 1201 and the negative column 1202 of each storage battery 12. In addition, the second conductive strip 27 connects the positive and negative electrodes of two adjacent storage batteries 12, which can realize the series connection of multiple storage batteries 12 and provide a higher output voltage. Therefore, it is convenient to adjust the multiple storage batteries 12 to be connected in parallel or in series according to different charging scenarios, which is more convenient and quick to use and has a better charging effect.

[0042] During use, when the battery 12 needs to be cooled, the fan 16 is started to perform the exhaust operation, so that the external air enters through the heat exchange hole 14 on one side, and is discharged after passing through the fixed box 901 and the air outlet pipe 902. At the same time, when passing through the annular cover 13, the internal coolant can cool the incoming air, so that the cooling efficiency and effect of the battery 12 are higher. At the same time, when the air enters the fixed box 901, it impacts the surface of the rotating fan 904 to rotate it, and drives the rotating shaft 903 and the rotating disk 905 to rotate. When the protrusion 906 abuts against the side wall of the fixed block 908, the L-shaped plate 907 is pushed to move upward, and the piston 702 is driven to move upward. At the same time, the fourth spring 803 is compressed. When the protrusion 906 passes over the fixed block 908, the piston 702 and the L-shaped plate 907 can move downward and reset under the action of the fourth spring 803. This reciprocating process can make the piston 702 reciprocate within a certain range in the cooling box 701.

[0043] When the piston 702 moves upward, negative pressure is generated in the cooling box 701. At the same time, the first one-way valve is opened and the second one-way valve is closed. At this time, the coolant in the heat exchange hole 14 enters the cooling box 701 through the liquid inlet pipe 703. When the piston 702 moves downward, the coolant in the cooling box 701 can be squeezed. At the same time, the first one-way valve is closed and the second one-way valve is opened. At this time, the coolant in the cooling box 701 is squeezed and returned to the annular cover 13 through the liquid outlet pipe 704. In this way, the coolant in the heat exchange hole 14 can be circulated and cooled, so that the cooling efficiency is higher and the effect is better.

[0044] Furthermore, in a low temperature state, the second movable assembly 601 is started to drive the second movable plate 602 to move downward, and at the same time, the sealing plate 603 is driven to move downward synchronously and seal the heat exchange hole 14, thereby ensuring the sealing state of the battery box 1 and being able to keep the battery 12 warm. At the same time, when the second movable plate 602 moves downward, the piston 702 is pulled upward by the pull rope 1003, so that the coolant in the heat exchange hole 14 can be completely drawn into the cooling box 701 for temporary storage, and a vacuum state is formed in the heat exchange hole 14, thereby better keeping the battery 12 warm, thereby ensuring its use effect and lifespan. Moreover, when the temperature sensor 11 detects that the temperature in the battery box 1 is high, it can also dissipate heat appropriately inside it.
