[0021] An embodiment of the present utility model provides a battery pack with a protection function, as Figures 1-4 shown. The battery pack with a protection function includes: a plurality of rectangular battery blocks 1; a plurality of card sleeves 2, and the plurality of card sleeves 2 are respectively sleeved on the eight corners of each battery block 1, and the card sleeves are in a bent angle shape; a connecting rod 3, one end of the connecting rod 3 is fixed on two sides of each card sleeve 2; a protective shell 4, the protective shell 4 surrounds the plurality of battery blocks and the inner wall is fixedly connected to the other end of the connecting rod; a plurality of support plates 6, one end of the plurality of support plates 6 is installed on the outer surface of the protective shell 4; an isolation assembly, and the isolation assembly surrounds the protective shell 4 through the other ends of the plurality of support plates.

[0022] In this embodiment, the battery block 1 serves as the basic energy unit of the battery pack, responsible for storing and providing electrical energy. Multiple card sleeves 2 cooperate to play a role in fixing and positioning the battery block 1. The connecting rod 3 not only strengthens the connection strength between the battery block 1 and the protective case 4, but also forms a stable framework to prevent the battery block 1 from directly contacting the protective case 4, reducing the risk of the battery block 1 being damaged together with the protective case 4 after being impacted. The protective case 4 forms a complete protective layer to protect the multiple internal battery blocks 1 from external impacts and damages. The support plate 6 is used to further enhance the structural strength of the protective case 4, providing additional fixing points and support surfaces for the protective case 4. The isolation component can not only provide additional buffering when the battery pack is impacted, further reducing the impact on the internal battery block 1, but also has other protective functions such as heat insulation and dust prevention.

[0023] In a further preferred embodiment of the present utility model, the isolation component includes a top shell 7, a bottom shell 8, and a sealing ring 9. The inner wall of the top shell 7 is in contact with the other end of the support plate located on the upper surface of the protective case. The inner wall of the bottom shell 8 is in contact with the other end of the support plate located on the lower surface of the protective case. The lower edge of the top shell 7 and the upper edge of the bottom shell 8 are correspondingly matched. The sealing ring 9 is fixed on the outer side of the lower edge of the top shell 7 and overlaps with the upper edge of the bottom shell 8. The sealing ring 9 is used to seal the gap between the top shell 7 and the bottom shell 8. Waterproof glue is applied between the sealing ring 9 and the bottom shell 8.

[0024] In this embodiment, the top shell 7 and the bottom shell 8 cooperate to provide additional protection for the protective case 4, reducing the influence of external factors such as direct sunlight on the battery block 1. At the same time, it also isolates external objects to prevent heat dissipation difficulties caused by the accumulation of items, thereby triggering dangerous accidents. The main function of the sealing ring 9 is to seal the gap between the top shell 7 and the bottom shell 8 to prevent the penetration of external substances such as dust. In addition, the waterproof glue applied between the sealing ring 9 and the bottom shell 8 further enhances the sealing effect.

[0025] In a further preferred embodiment of the present utility model, multiple heat dissipation openings 10 are provided on both the top shell 7 and the bottom shell 8. Dust-proof nets 11 for isolating impurities are installed in the multiple heat dissipation openings 10. Soft PVC plastic layers are provided on the outer walls of the top shell 7 and the bottom shell 8.

[0026] In this embodiment, the main function of the heat dissipation vent 10 is to promote the heat dissipation inside the battery pack to prevent performance degradation or safety hazards caused by excessive temperature. The design of the heat dissipation vent 10 enables the battery pack to maintain a stable temperature under long-term high-load operation, thereby extending the service life. The dustproof net 11 is used to isolate impurities such as dust and particles in the air to prevent them from entering the battery pack through the heat dissipation vent 10, thereby improving the reliability and stability of its operation. The soft PVC plastic layer not only enhances the durability of the battery pack shell, making it less likely to be scratched or damaged in daily use, but also improves the comfort and safety when holding it. In addition, the soft PVC plastic layer also has a certain buffering effect, which can reduce the impact of external impact on the inside of the battery pack to a certain extent.

[0027] In a further preferred embodiment of the utility model, the protective shell 4 is made of metal, and a ceramic insulating layer 5 is provided on the inner wall of the protective shell 4. The ceramic insulating layer 5 is connected to the other ends of the multiple connecting rods 3, and the multiple connecting rods 3 are all made of ceramic composite materials.

[0028] In this embodiment, the protective shell 4 made of metal has higher strength and rigidity, and can better resist external impact and extrusion. The metal material also has good thermal conductivity, which helps to dissipate heat inside the battery pack and improve heat dissipation efficiency. The design of the ceramic insulating layer 5 is mainly to improve the insulation performance of the battery pack, and can effectively isolate the electrical components inside the battery pack from the external environment to prevent the occurrence of safety hazards such as short circuit and leakage. The ceramic composite material combines the high strength, high hardness and excellent insulation performance of ceramic materials, as well as certain properties of other materials (such as metals, resins, etc.), so that the connecting rod 3 can maintain excellent insulation and corrosion resistance while bearing a large load. In addition, the connecting rod 3 of the ceramic composite material can also effectively reduce the overall weight of the battery pack and improve the energy density.

[0029] In a further preferred embodiment of the utility model, two handles 13 are installed on the top of the top shell 7 through fixing bolts 15, and two support blocks 12 are fixed on the bottom of the bottom shell 8, and the support blocks 12 are used to isolate ground pollutants.

[0030] In this embodiment, the design of the handle 13 enables the user to easily lift and carry the battery pack, thereby improving the portability of the battery pack. In scenarios where the battery pack needs to be moved or installed, this design can greatly reduce the user's labor intensity and operating difficulty, thereby improving work efficiency. The main function of the support block 12 is to isolate ground pollutants to prevent the bottom of the battery pack from being contaminated or damaged when it is in direct contact with the ground. Ground pollutants may include moisture, oil stains, dust, etc., which may cause corrosion or short circuits to the metal parts of the battery pack. Through the isolation effect of the support block 12, the battery pack can keep the bottom clean and dry, thereby extending its service life.

[0031] In a further preferred embodiment of the utility model, isolation pads 14 are pasted on both sides of the multiple battery blocks 1, and the multiple isolation pads 14 are provided with heat dissipation holes. The multiple isolation pads 14 are in contact with each other, and the isolation pads 14 are used to isolate the multiple battery blocks 1.

[0032] In this embodiment, the main function of the isolation pad 14 is to isolate adjacent battery blocks 1 to prevent direct contact and potential short circuit risks between them. This isolation measure helps to improve the safety of the battery pack and reduce malfunctions caused by improper contact between battery blocks 1. The heat dissipation holes allow air circulation, which helps to dissipate the heat generated by the battery block 1 during operation in a timely manner. The design of the heat dissipation holes not only improves the heat dissipation efficiency of the battery pack, but also helps to keep the battery block 1 operating within a suitable operating temperature range and extend its service life. The arrangement of two-to-two contact not only ensures effective isolation between the battery blocks 1, but also makes the structure of the entire battery pack compact and orderly, thereby improving space utilization and overall aesthetics.

[0033] In a further preferred embodiment of the present invention, a plurality of finger holes 16 are provided on the plurality of support plates 6 , and the plurality of finger holes 16 can serve as finger support points, and rubber pads 17 are fixed in the plurality of finger holes 16 .

[0034] In this embodiment, the isolation component is opened, and the user can insert a finger into the finger hole 16 to more stably hold or operate the support plate 6, thereby achieving the transportation, installation or adjustment of the protective shell 4. The rubber pad 17 has the characteristics of softness, non-slipness and wear resistance. It can not only increase the friction between the user's finger and the finger hole 16 to prevent the finger from slipping during transportation or operation, but also provide a comfortable touch to reduce the discomfort caused by long-term holding.

[0035] To sum up, compared with the related art, the present device provides a protective shell 4 to perform preliminary isolation and protection on the battery block 1, thereby preventing external sewage and dust from affecting the battery block 1, and can also buffer the impact from the outside. The protection effect can be further increased by providing an isolation component, which can effectively isolate the debris accumulated next to the battery pack, ensure that the battery pack can dissipate heat normally, and reduce the probability of safety hazards. At the same time, there is an isolation space between the isolation component and the protective shell 4 through the support plate 6, and there is an isolation space between the protective shell 4 and the battery block 1 through the connecting rod 3, which further reduces the impact of external impact on internal components. The portability of the device is increased by providing a detachable handle 13. At the same time, the handle 13 can be removed after the device is installed to make the surface of the device smoother.
