[0043] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0044] This embodiment provides a battery box, which can be applied to lockers such as express cabinets and intelligent vending cabinets. A battery is placed in the battery box, and the battery powers electrical components such as an electronic control lock and an operation screen in the locker in case of accidental power failure.

[0045] Please refer to Figures 1 to 3 , this battery box includes a box body 1, a battery 2, an intake fan 3 and an exhaust fan 4. An air inlet 112 and an air outlet 113 are formed on the box wall of the box body 1; the battery 2 is fixed in the box body 1, and there are intervals between the four sides of the battery 2 and the box wall of the box body 1, and the four sides of the battery 2 and the box wall of the box body 1 jointly define an annular channel 17. Both the air inlet 112 and the air outlet 113 are communicated with the annular channel 17; both the intake fan 3 and the exhaust fan 4 are fixedly connected to the box wall, and the intake fan 3 is opposite to the air inlet 112, and the exhaust fan 4 is opposite to the air outlet 113. For the battery box provided in this embodiment, the battery 2 is fixed in the box body 1. The intake fan 3 is used to drive external air to enter the box body 1 through the air inlet 112, and the exhaust fan 4 is used to discharge the air in the box body 1 to the outside through the air outlet 113. The air entering the box body 1 can flow from the air inlet 112 to the air outlet 113 along the annular channel 17 between the four sides of the battery 2 and the box wall of the box body 1. Please refer to Figure 2 , the air flow flowing through the annular channel 17 mainly follows two paths. One path does not bypass the battery 2 and is shorter, and the other path bypasses the battery 2 and is longer and roughly U-shaped. The two paths together form the entire annular channel 17, so that air flows through all four sides of the battery 2 to take away the heat generated by the battery 2 in time. Therefore, the battery 2 can be quickly cooled, and the heat dissipation performance of the battery 2 in a high-temperature environment can be significantly improved.

[0046] It should be noted that in this embodiment, the installation positions of the intake fan 3 and the exhaust fan 4 are not limited. According to actual needs, the intake fan 3 and the exhaust fan 4 can also be respectively arranged on two different box walls of the box body 1. For example, the intake fan 3 and the exhaust fan 4 are respectively arranged on two box walls of the box body 1 that are spaced apart and parallel; or, the intake fan 3 and the exhaust fan 4 can also be respectively arranged on two box walls of the box body 1 that are connected at an angle.

[0047] In this embodiment, an exemplary solution is given where the number of the intake fan 3 and the exhaust fan 4 is both one. In other embodiments, the number of the intake fan 3 and the exhaust fan 4 can also be set according to actual needs. For example, the number of both the intake fan 3 and the exhaust fan 4 is two. Among them, the two intake fans 3 and the two exhaust fans 4 can both be arranged on the first side wall 11; or, one intake fan 3 and one exhaust fan 4 are simultaneously arranged on the first side wall 11, and the other intake fan 3 and the other exhaust fan 4 are simultaneously arranged on another side wall of the box body 1.

[0048] Optionally, please continue to refer to Figures 1 to 3 , the box wall includes a first side wall 11, a second side wall 12, a third side wall 13, a fourth side wall 14, a top wall 15 and a bottom wall 16. The first side wall 11 and the second side wall 12 are spaced apart and arranged in parallel in the front-rear direction (such as Figure 1 the direction indicated by the arrow ab in Figure 1 ), the third side wall 13 and the fourth side wall 14 are spaced apart and arranged in parallel in the left-right direction (such as Figure 1 the direction indicated by the arrow cd in

[0049] ), the top wall 15 and the bottom wall 16 are spaced apart and arranged in parallel in the up-down direction (such as Figure 1 the direction indicated by the arrow ef in

[0049] ). The third side wall 13 and the fourth side wall 14 are both connected between the top wall 15 and the bottom wall 16. The first side wall 11 is simultaneously connected to the front ends of the third side wall 13, the bottom wall 16, the fourth side wall 14 and the top wall 15. The second side wall 12 is simultaneously connected to the rear ends of the third side wall 13, the bottom wall 16, the fourth side wall 14 and the top wall 15. The battery 2 is fixed to the bottom wall 16, and there are intervals between the four sides of the battery 2 and the first side wall 11, the second side wall 12, the third side wall 13 and the fourth side wall 14. The annular channel 17 is jointly defined by the four sides of the battery 2 and the first side wall 11, the second side wall 12, the third side wall 13 and the fourth side wall 14, and the battery 2 is simultaneously spaced apart from the intake fan 3 and the exhaust fan 4. The battery 2 is a cube with six faces. The bottom surface of the battery 2 faces the bottom wall 16, and the top surface of the battery 2 faces the top wall 15. The annular channel 17 is jointly formed by the gaps between the peripheral side surfaces of the battery 2 connected between the top surface and the bottom surface and the first side wall 11, the third side wall 13, the second side wall 12 and the fourth side wall 14. The two paths for the air flow to flow from the air inlet 112 through the annular channel 17 to the air outlet 113 are the first path and the second path respectively. The first path is located in the gap between the battery 2 and the first side wall 11. The first path is shorter and flows through one side surface of the four peripheral side surfaces of the battery 2. The second path is located in the gaps between the battery 2 and the third side wall 13, the second side wall 12 and the fourth side wall 14. The second path is longer and flows through the other three side surfaces of the four peripheral side surfaces of the battery 2. Thus, the air flow of the two paths can flow through the four sides of the battery 2, which is beneficial to the heat dissipation of the battery 2.In this embodiment, the air inlet 112 and the air outlet 113 are arranged side by side on the first side wall 11. In other embodiments, the air inlet 112 and the air outlet 113 are respectively arranged on two adjacent or opposite ones of the first side wall 11, the second side wall 12, the third side wall 13, and the fourth side wall 14. For example, the air inlet 112 is arranged on the first side wall 11 and the air outlet 113 is arranged on the second side wall 12, or the air inlet 112 is arranged on the third side wall 13 and the air outlet 113 is arranged on the fourth side wall 14; or the air inlet 112 is arranged on the first side wall 11 and the air outlet 113 is arranged on the third side wall 13 or the fourth side wall 14.

[0050] It should be noted that the air inlet fan 3 is opposite to the air inlet 112. Therefore, when the air inlet 112 is arranged on any one of the four side walls of the box body 1, the air inlet fan 3 is fixedly connected to that side wall. For example, when the air inlet 112 is arranged on the third side wall 13, the air inlet fan 3 is fixedly connected to the third side wall 13 to be opposite to the air inlet 112.

[0051] It should be noted that the air outlet fan 4 is opposite to the air outlet 113. Therefore, when the air outlet 113 is arranged on any one of the four side walls of the box body 1, the air outlet fan 4 is fixedly connected to that side wall. For example, when the air outlet 113 is arranged on the second side wall 12, the air outlet fan 4 is fixedly connected to the second side wall 12 to be opposite to the air outlet 113.

[0052] In this embodiment, both the air inlet 112 and the air outlet 113 are arranged side by side on the first side wall 11, and both the air inlet fan 3 and the air outlet fan 4 are fixedly connected to the first side wall 11 so that the air inlet fan 3 is opposite to the air inlet 112 and the air outlet fan 4 is opposite to the air outlet 113.

[0053] In other embodiments, the cross-sectional shape of the box body 1 is not limited to the rectangular cross-sectional shape in this embodiment and can also be set according to actual needs; in addition, in other embodiments, the first side wall 11 and the second side wall 12 can also be arranged at intervals and in parallel in the left-right direction, and the third side wall 13 and the fourth side wall 14 are correspondingly arranged at intervals and in parallel in the front-back direction.

[0054] Optionally, please refer to Figure 2 , the battery box further includes a pressing plate 7. The pressing plate 7 covers the battery 2 and is connected to the bottom wall 16. The pressing plate 7 is used to fix the position of the battery 2. Further optionally, the battery box further includes a plurality of limiting blocks 6 arranged on the bottom wall 16. The plurality of limiting blocks 6 are located around the battery 2, and the plurality of limiting blocks 6 are used to limit the relative position of the battery 2 and the bottom wall 16 in the front-back direction and the left-right direction.

[0055] Optionally, the battery 2 is spaced from the top wall 15. Therefore, when the air flow in the box body 1 flows from the air inlet 112 to the air outlet 113, a part of the air flow can also blow through the gap between the top surface of the battery 2 and the top wall 15 to further enhance the heat dissipation effect of the battery 2.

[0056] Optionally, please refer to Figures 3 to 5 , the first side wall 11 includes a first plate 111 and a second plate 114 perpendicularly connected to the first plate 111. The air inlet 112 and the air outlet 113 are both opened on the first plate 111. The air inlet fan 3 and the air outlet fan 4 are both fixedly connected to the first plate 111. The second plate 114 is provided with a slot 115; the battery box further includes a dust-proof component 5, the dust-proof component 5 is detachably inserted into the slot 115, and the dust-proof component 5 is arranged opposite to the air inlet fan 3 and the air outlet fan 4 at the same time. By providing the dust-proof component 5 opposite to the air inlet fan 3 and the air outlet fan 4, it is possible to prevent dust and other sundries from being brought into the interior of the box body 1 during the air flow, ensure that the battery 2 and each fan can work reliably, and further ensure the heat dissipation effect of the battery 2; at the same time, since the dust-proof component 5 is detachably inserted and matched with the slot 115, when a certain amount of sundries accumulate on the dust-proof component 5, the dust-proof component 5 can be directly pulled out from the slot 115, which is convenient for cleaning the dust-proof component 5 or replacing it with a new dust-proof component 5; in addition, the dust-proof component 5, the air inlet fan 3 and the air outlet fan 4 are all connected to the first side wall 11, which is convenient for the disassembly, assembly and maintenance of the three. Specifically, in this embodiment, the air inlet fan 3 and the air outlet fan 4 are installed on the side of the first plate 111 adjacent to the battery 2, that is, the air inlet fan 3 and the air outlet fan 4 are located inside the box body 1; the dust-proof component 5 is located on the side of the first plate 111 away from the battery 2. In other embodiments, it is also possible to make the air inlet fan 3, the air outlet fan 4 and the dust-proof component 5 all located on the side of the first plate 111 adjacent to the battery 2.

[0057] As an alternative solution, the slot 115 can also be provided on the top wall 15 or the bottom wall 16 of the box body 1, and the detachable insertion of the dust-proof component 5 into the slot 115 can also be realized, and the dust-proof component 5 is arranged opposite to the air inlet fan 3 and the air outlet fan 4 at the same time.

[0058] In other embodiments, dust-proof components 5 can also be provided corresponding to the air inlet fan 3 and the air outlet fan 4 respectively according to actual needs, or a dust-proof component 5 can be provided only corresponding to the air inlet fan 3.

[0059] Optionally, please continue to refer to Figure 3 and Figure 4, the first plate 111 and the second side wall 12 are spaced apart and parallel to each other in the front-rear direction. The first plate 111 is simultaneously connected to the front ends of the third side wall 13, the bottom wall 16, the fourth side wall 14, and the top wall 15. The second plate 114 is flush with the top wall 15. The first side wall 11 further includes two side plates 116 that are spaced apart and parallel to each other in the left-right direction. Both side plates 116 are located between the third side wall 13 and the fourth side wall 14. In the left-right direction, one of the two side plates 116 is angularly connected to the first end of the first plate 111 and / or the first end of the second plate 114, and the other of the two side plates 116 is angularly connected to the second end of the first plate 111 and / or the second end of the second plate 114. With such a setting, during installation, the intake fan 3, the exhaust fan 4, and the dust-proof component 5 can be respectively installed on the first side wall 11 first, and then the first side wall 11 can be installed between the third side wall 13 and the fourth side wall 14, and the installation operation is simple and convenient.

The limiting plate 118 is arranged opposite to and parallel to the first plate 111 at a certain interval. The dust-proof component 5 is clamped between the limiting plate 118 and the first plate 111. With such a setting, after the dust-proof component 5 is inserted into the slot 115, in the front-rear direction, the dust-proof component 5 is clamped between the first plate 111 and the limiting plate 118, so that the dust-proof component 5 is closely attached to the first plate 111, and the dust-proof component 5 and the air inlets 112 and air outlets 113 on the first plate 111 can be relatively seamless, ensuring that when the external air flow enters the intake fan 3 through the air inlet 112, the impurities carried therein can be removed by the dust-proof component 5.
