[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 6As shown, the utility model provides a movable photovoltaic energy storage lithium battery pack, including a base 1, four universal wheels 2 are fixedly installed at the bottom of the base 1, a handle 3 is fixedly installed on one side of the outer wall of the base 1, and two installation boxes 4 are movably connected to the top of the base 1, a group of card slots 5 are opened on the top of the base 1 and the two installation boxes 4, and two groups of first slide grooves 6 are opened on the inner surface walls of the two installation boxes 4, and sliding cabinets 7 are slidably embedded between the inner surface walls of the four groups of first slide grooves 6, and a group of second slide grooves 8 are opened on the inner surface walls of the four slide cabinets 7, and slide plates 9 are slidably embedded between the inner surface walls of the four groups of second slide grooves 8, and the tops of the four slide plates 9 are fixedly connected to the battery pack body 10, and the inner surface walls of the four slide cabinets 7 are fixedly connected to four groups of first buffer springs 11, and the outer walls of the sixteen groups of first buffer springs 11 are fixedly connected to rubber pads 12, and the four The inner surface wall of the sliding cabinet 7 is fixedly connected with a group of fixing rods 13, the outer surface walls of the four groups of fixing rods 13 are movably sleeved with two second buffer springs 14, the outer surface walls of the four groups of fixing rods 13 are movably sleeved with two sliding seats 15, one side of the outer wall of the eight groups of sliding seats 15 is provided with a first movable groove 16, the inner surface walls of the eight groups of first movable grooves 16 are movably inserted with first movable rods 17, the outer surface walls of the eight groups of first movable rods 17 are movably sleeved with connecting plates 18, one side of the outer wall of the eight groups of connecting plates 18 is provided with a second movable groove 19, the inner surface walls of the eight groups of second movable grooves 19 are movably inserted with second movable rods 20, the outer surface walls of the eight groups of second movable rods 20 are movably sleeved with fixing blocks 21, and the bottoms of the four slides 9 are fixedly connected to the tops of the eight groups of fixing blocks 21, and the top of one of the two installation boxes 4 is movably connected with a top cover 22.

[0026] The effect achieved by the entire embodiment 1 is that four universal wheels 2 are fixedly installed at the bottom of the base 1, and a handle 3 is fixedly installed on one side of the outer wall of the base 1, so that the photovoltaic energy storage lithium battery pack has convenient mobility. When the battery pack body 10 inside the sliding cabinet 7 is subjected to external impact, four groups of first buffer springs 11 are fixedly installed through the inner surface wall of the sliding cabinet 7, and the outer surfaces of the four groups of first buffer springs 11 are fixedly connected with rubber pads 12. The four groups of first buffer springs 11 and the four groups of rubber pads 12 can effectively absorb and disperse the impact force, and the four groups of first buffer springs 11 and the four groups of rubber pads 12 are evenly distributed on the four sides of the inner wall of the sliding cabinet 7. Therefore, no matter which direction the impact comes from, it can be evenly and effectively buffered, and the battery pack body 10 is installed on the sliding plate 9. At the top, when the battery pack body 10 is impacted, the slide plate 9 will squeeze the two groups of connecting plates 18 at the bottom. After being squeezed, the two groups of connecting plates 18 will respectively push the two groups of sliding seats 15 to move. The two groups of sliding seats 15 will respectively squeeze the two groups of second buffer springs 14 during the movement, thereby further enhancing the overall buffering effect and protecting the safety of the battery pack body 10. This design not only improves the mobility of the photovoltaic energy storage lithium battery pack, but also significantly enhances its impact resistance during transportation. The installation box 4 adopts a modular design. When the number of battery pack bodies 10 to be installed needs to be increased, only the card block 23 needs to be inserted into the corresponding card slot 5 and the fixing bolt 25 needs to be tightened to achieve rapid and stable expansion, thereby improving the flexibility and maintainability of the entire system.

[0027] Embodiment 2, as Figure 2-Figure 6 As shown, the two installation boxes 4 and the bottom of the top cover 22 are fixedly connected with a block 23, and the three groups of blocks 23 are movably inserted into the three groups of slots 5, the outer wall side of the three groups of blocks 23 is provided with a threaded groove 24, the inner surface wall of the three groups of threaded grooves 24 is threadedly connected with fixing bolts 25, four first fans 26 are fixedly installed on the inner surface wall of the base 1, four dust cover plates 27 are fixedly installed on the outer wall side of the base 1, two second fans 28 are fixedly installed on the top of the top cover 22, and two dust covers 29 are fixedly installed on the top of the top cover 22.

[0028] The effect achieved by the entire embodiment 2 is that the photovoltaic energy storage lithium battery will generate a lot of heat due to various factors during use. If this heat cannot be dissipated in time and effectively, it will damage the internal structure of the lithium battery and affect its electrochemical performance and service life. After the lithium battery pack is installed and used, two second fans 28 are fixedly installed on the top of the top cover 22, and multiple groups of ventilation holes are opened on the top of the slide plate 9. After the two second fans 28 are started, they can quickly suck out the hot air in the box, thereby forming a negative pressure environment in the box, and four first fans 26 are fixedly installed on the inner surface wall of the base 1. After the four first fans 26 are started, they will continuously inhale cold air from the outside. This heat dissipation design based on the convection principle realizes the effective exchange of hot air in the box and cold air from the outside, thereby greatly reducing the temperature of the lithium battery pack and ensuring its normal operation. Four dust cover plates 27 are fixedly installed on one side of the outer wall of the base 1, and two dust covers 29 are fixedly installed on the top of the top cover 22, thereby effectively preventing dust, debris, etc. from entering the interior of the lithium battery pack, ensuring the smooth operation of the heat dissipation system.

[0029] Working principle: First, the staff can easily move the lithium battery pack to the designated position by pushing the handle 3. During the transportation or use of the lithium battery pack, the battery pack body 10 inside the sliding cabinet 7 will inevitably be affected to a certain extent due to various external impacts and vibrations that may be encountered. In order to alleviate this impact, a group of first buffer springs 11 and a group of rubber pads 12 are arranged on the four sides of the inner wall of the sliding cabinet 7. Regardless of the direction of the impact on the battery pack body 10, a group of first buffer springs 11 and a group of rubber pads 12 can quickly absorb and disperse the impact force, thereby effectively protecting the battery pack body 10 from damage, and the battery pack body 10 is installed on the top of the slide plate 9. When the battery pack body 10 is impacted, the slide plate 9 will quickly transfer the impact force to the two groups of connecting plates 18 at the bottom. After the two groups of connecting plates 18 are squeezed, they will push the two groups of sliding seats 15 to move respectively. During the movement of the two groups of sliding seats 15, they will squeeze the two groups of second buffer springs 14 respectively, thereby further increasing The overall buffering effect is enhanced to ensure the safety of the battery pack body 10, and the base 1, the installation box 4 and the top cover 22 are all quickly engaged through the cooperation of the card block 23 and the card slot 5, and are strengthened and fixed by the fixing bolts 25. This modular design makes the expansion of the lithium battery pack very simple. When more battery pack bodies 10 need to be installed, it is only necessary to increase the number of installation boxes 4 and insert the card block 23 into the corresponding card slot 5 to easily achieve expansion. When the battery pack body 10 needs to be maintained or replaced, the slide cabinet 7 can be easily moved out from the corresponding set of first slide slots 6. After the lithium battery pack is installed and used, the staff will power on the four first fans 26 and the two second fans 28. After power on, the two second fans 28 suck out the hot air in the box through the negative pressure principle, while the four first fans 26 continuously inhale the cold air from the outside. Through this hot and cold air convection method, the effective heat dissipation of the lithium battery pack is achieved, ensuring its stability and safety during operation.
