[0041] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] like Figure 1-Figure 3 As shown, this embodiment provides an energy storage power supply, which includes a battery assembly 300 and an energy storage box. The energy storage box includes a hollow shell 200, and the battery assembly 300 is installed in the hollow shell 200. Ventilation holes 210 are respectively provided on opposite sides of the hollow shell 200, and ventilation assemblies 100 are respectively installed on the two ventilation holes 210. The ventilation assemblies 100 can not only cover the ventilation holes 210 of the energy storage box, but also realize the internal and external ventilation of the energy storage box.

[0043] Further, such as Figure 1-Figure 8 As shown, the ventilation assembly 100 includes a ventilation plate 10 and a blowing member 20, the ventilation plate 10 is provided with a shielding portion 11 and a ventilation window 12, the shielding portion 11 is arranged above the ventilation window 12; the blowing member 20 is arranged on the inner side of the ventilation plate 10, the blowing member 20 is installed on the shielding portion 11, the blowing member 20 has an air inlet end and an air outlet end, one of the air inlet end and the air outlet end of the blowing member 20 is connected to the outside of the ventilation plate 10 through the ventilation window 12, and the other is arranged toward the battery assembly 300 in the hollow shell 200.

[0044] Specifically, the ventilation assembly 100 provided in this embodiment blocks the vent 210 of the energy storage box through the ventilation plate 10, the shielding portion 11 and the ventilation window 12 on the ventilation plate 10 are staggered up and down, and the air inlet or outlet of the air blowing member 20 is connected to the outside of the ventilation plate 10 through the ventilation window 12, so as to dissipate heat by blowing or exhausting air. At the same time, since the air blowing member 20 is installed on the inner side of the shielding portion 11, it is avoided that the air blowing member 20 is directly exposed to the outside world, and the external liquid enters the energy storage box through the air blowing member 20, thereby achieving better waterproof performance. In addition, the setting that the air blowing member 20 is directly installed on the ventilation plate 10 enables the energy storage box to achieve modular assembly and improve assembly efficiency.

[0045] For example, the air inlet end of the air blowing member 20 in one ventilation assembly 100 is connected to the outside through the ventilation window 12, and the air outlet end of the air blowing member 20 in another ventilation assembly 100 is connected to the outside through the ventilation window 12. Figure 3 As shown, by arranging the blowing members 20 in the two ventilation assemblies 100 in opposite directions, an inverted U-shaped heat dissipation airflow field is formed in the energy storage box, thereby achieving efficient heat dissipation inside the energy storage power supply.

[0046] In this embodiment, the air blowing member 20 is a heat dissipation fan, such as an axial flow fan or a centrifugal fan, which has a simple structure and is easy to install. In other embodiments of the utility model, the air blowing member 20 can also be a rotary blower or other components capable of generating airflow.

[0047] For example, Figure 4-Figure 8 As shown, the ventilation window 12 is provided with a plurality of ventilation holes 121 arranged in a matrix, and the ventilation holes 121 communicate with the inner side and the outer side of the ventilation plate 10. The shielding portion 11 is provided as a closed structure, and the air blowing member 20 is wrapped in the energy storage box by the shielding portion 11, so as to reduce the noise transmitted when the air blowing member 20 is working; the shielding portion 11 is specifically provided as a plurality of closed-cell structures distributed in a matrix, so that its appearance is consistent with the ventilation window 12, and the appearance of the ventilation plate 10 is more coordinated.

[0048] For example, Figure 5 , Figure 7 and Figure 8As shown, the ventilation assembly 100 also includes a windshield 30, which is installed on the inner side of the ventilation plate 10, and the windshield 30 covers the ventilation window 12. The heat dissipation duct 1 is formed between the windshield 30 and the ventilation plate 10, and the air blowing member 20 is connected to the ventilation window 12 through the heat dissipation duct 1. Specifically, a gap is provided between the air blowing member 20 and the shielding portion 11, and the air inlet end or the air outlet end of the air blowing member 20 is connected to the heat dissipation duct 1 through the gap, and then connected to the outside through the heat dissipation duct 1, and the airflow inhaled or blown out by the air blowing member 20 flows through the heat dissipation duct 1. The setting of the windshield 30 can form the heat dissipation duct 1 on the one hand, improve the efficiency of the air blowing member 20 in driving the airflow flow, and on the other hand, it can also prevent external liquids such as rainwater from directly entering the energy storage box, thereby improving the waterproof performance.

[0049] For example, Figure 5-Figure 8 As shown, a first sealing rib 13 is provided on the inner side of the shielding portion 11, and the first sealing rib 13 is located between the shielding portion 11 and the air blowing member 20. The first sealing rib 13 extends around the circumference of the air blowing member 20 to form a guide cavity 2, and the guide cavity 2 is provided with a guide port connected to the heat dissipation duct 1. Specifically, the first sealing rib 13 is extended in a square frame shape, and the guide port is provided at the lower end of the guide cavity 2. The air inlet end or the air outlet end of the air blowing member 20 is connected to the heat dissipation duct 1 through the guide cavity 2 and the guide port. The provision of the first sealing rib 13 further improves the airtightness of the connecting duct between the air blowing member 20 and the ventilation window 12, making the airflow between the two more dense and less scattered, and further improving the heat dissipation efficiency of the air blowing member 20.

[0050] For example, Figure 5-Figure 8 As shown, a second sealing rib 122 is provided on the inner side of the ventilation plate 10 around the circumference of the ventilation window 12. The second sealing rib 122 is extended in a square frame shape. The second sealing rib 122 seals the periphery of the heat dissipation duct 1. The guide port runs through the upper end of the second sealing rib 122, so that the guide cavity 2 is connected to the heat dissipation duct 1. The provision of the second sealing rib 122 further improves the airtightness of the heat dissipation duct 1, reduces the airflow loss caused by the airflow overflowing through the periphery of the heat dissipation duct 1, and further improves the heat dissipation efficiency of the air blowing member 20.

[0051] Of course, in other embodiments, the air guide port may also be provided on the side of the first sealing rib 13 , and the air guide port is connected to the heat dissipation duct 1 through an additionally provided pipeline structure.

[0052] For example, Figure 7As shown, a sealing portion 31 is provided at the upper end of the wind shield 30, and the sealing portion 31 extends between the flow guide cavity 2 and the air blowing member 20 and covers the flow guide port, and the sealing portion 31 blocks the gap between the air blowing member 20 and the first sealing rib 13, thereby reducing air leakage. The upper edge of the sealing portion 31 is set as an arc-shaped structure that matches the air inlet end or the air outlet end of the air blowing member 20, while ensuring the sealing performance, it does not affect the effective operation of the air blowing member 20.

[0053] For example, Figure 6-Figure 8 As shown, the ventilation assembly 100 also includes a dustproof net 40, which is arranged between the air inlet end or the air outlet end of the air blowing member 20 and the ventilation window 12. Specifically, the dustproof net 40 is installed at one end of the air blowing member 20 facing the shielding portion 11, and is located between the air blowing member 20 and the first sealing rib 13. The provision of the dustproof net 40 improves the dustproof performance of the ventilation assembly 100, so that the overall protection level of the energy storage box can reach IP66. By reducing dust ingress, the service life of the air blowing member 20 and the battery assembly 300 is increased, and the reliability of the air blowing member 20 and the battery assembly 300 is improved.

[0054] Illustratively, the mounting structure of each component in the ventilation assembly 100 is simple and compact, with a smaller volume and outstanding design advantages.

[0055] Specifically, Figure 7 As shown, the air blowing member 20 is provided with a plurality of first through holes 21, and the air blowing member 20 is locked to the ventilation plate 10 by a plurality of fastening screws which are correspondingly passed through the first through holes 21. Specifically, a threaded hole is provided on the first sealing rib 13, and the fastening screws pass through the first through holes 21 and are connected with the corresponding threaded holes.

[0056] For example, Figure 7 As shown, a second through hole 32 is provided on the wind shield 30, and the wind shield 30 is locked to the ventilation plate 10 by means of a fastening screw passing through the second through hole 32; part of the first through hole 21 is coaxially arranged with the second through hole 32, and the corresponding fastening screw passes through the coaxial first through hole 21 and the second through hole 32 at the same time and is threadedly connected with the threaded hole on the first sealing rib 13.

[0057] For example, Figure 7 As shown, the dustproof net 40 is arranged on the side of the blowing member 20 facing the shielding portion 11, and a third through hole 41 is provided on the dustproof net 40. The dustproof net 40 is locked to the ventilation plate 10 by a fastening screw passing through the third through hole 41; part of the first through hole 21, the second through hole 32 and the third through hole 41 are coaxially arranged, and the corresponding fastening screws simultaneously pass through the coaxial first through hole 21, the second through hole 32 and the third through hole 41 and are threadedly connected with the threaded hole on the first sealing rib 13.

[0058] For example, Figure 7 and Figure 8As shown, the ventilation plate 10 is also provided with a drainage portion 14, which is arranged on the inner side of the bottom end of the ventilation window 12. The drainage portion 14 is provided with a drainage slope 141, which is arranged to be inclined downward from the inside to the outside, so as to accelerate the discharge of liquids such as rainwater entering through the ventilation window 12 and avoid liquid accumulation. In addition, the main body of the drainage portion 14 also encloses the bottom of the heat dissipation duct 1 to reduce air flow loss.

[0059] Exemplarily, the angle between the drainage slope 141 and the horizontal plane is greater than 30°.

[0060] For example, Figure 2 , Figure 5-Figure 8 As shown, the upper and lower edges and the left and right edges of the ventilation plate 10 are provided with snap-fit ​​portions 15. Correspondingly, the hollow shell 200 is provided with slot portions 201 around the vent 210. Each snap-fit ​​portion 15 is snapped into the slot portion 201 one by one to achieve the installation of the ventilation plate 10 and the hollow shell 200.

[0061] Exemplarily, the hollow shell 200 is assembled by buckling an upper shell and a lower shell.

[0062] When assembling the energy storage power supply, first install the air blowing member 20, the wind shield 30 and the dust screen 40 on the ventilation plate 10 respectively to form a ventilation assembly 100, then insert the two ventilation assemblies 100 on the lower shell, and snap the part of the buckle part 15 on the ventilation plate 10 with the slot part 201 on the lower shell, then install the battery assembly 300 into the lower shell, and then snap the upper shell to the lower shell, and snap the remaining buckle part 15 on the ventilation plate 10 with the slot part 201 on the upper shell, and finally connect the upper shell and the lower shell by fastening screws, so as to complete the assembly of the energy storage box and the entire energy storage power supply. It can be seen that the energy storage power supply can realize modular installation and improve assembly efficiency.

[0063] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
