[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] Please refer to the attached document. Figures 1-2 This application provides a battery cabinet 100 for storing batteries.

[0037] Please refer to the attached document. Figures 1-2In this embodiment, the battery cabinet 100 includes a housing 10, a waterproof component 20, and a filter cotton component 30. The housing 10 includes a bottom wall 11, a top wall 12, and a side wall 13. The bottom wall 11 and the top wall 12 are disposed at opposite ends of the side wall 13 and together form a receiving cavity 10a for placing batteries. The side wall 13 has multiple ventilation openings 13a communicating with the receiving cavity 10a. The ventilation openings 13a extend along the thickness direction of the side wall 13. The waterproof component 20 is connected to the side wall 13 and covers the ventilation openings 13a, forming an air duct 21. The air duct 21 is connected to the receiving cavity 10a and the vent 13a respectively, and is inclined toward the vent 13a. The filter cotton assembly 30 is connected to the waterproof assembly 20 and covers the air duct 21, so that the wind from the external environment flows through the vent 13a, the waterproof assembly 20 and the filter cotton assembly 30 to the receiving cavity 10a in sequence. This facilitates the multi-layer filtration of the wind from the external environment by the vent 13a, the waterproof assembly 20 and the filter cotton assembly 30, so as to achieve multi-layer protection and prevent dust, water or foreign objects from the external environment from entering the inside of the battery cabinet 100, thereby improving the protective effect of the battery cabinet 100.

[0038] Please refer to the attached document. Figures 1-2 In this embodiment of the application, the housing 10 serves as a supporting component of the battery cabinet 100, and the housing 10 is used to support the waterproof component 20 and the filter cotton component 30.

[0039] Please refer to the attached document. Figures 1-5 In this embodiment, the housing 10 includes a bottom wall 11, a top wall 12, and a side wall 13. The bottom wall 11 and the top wall 12 are disposed at opposite ends of the side wall 13 and together form a receiving cavity 10a. The receiving cavity 10a serves as the internal space of the housing 10 and is used to place batteries so that the batteries can be accommodated inside the housing 10 through the receiving cavity 10a, thereby facilitating the storage of batteries by the housing 10. The side wall 13 has multiple ventilation openings 13a that communicate with the receiving cavity 10a. The ventilation openings 13a extend along the thickness direction of the side wall 13 so that the wind from the external environment can flow into the receiving cavity 10a through the ventilation openings 13a, thereby facilitating the first layer of filtration of the wind from the external environment through the ventilation openings 13a, thereby facilitating the prevention of foreign objects and flying insects carried by the wind from the external environment, thereby achieving the first layer of protection.

[0040] By arranging multiple vents 13a, the flow efficiency of the external environment wind relative to the receiving cavity 10a is increased, thereby improving the flow velocity of the external environment wind relative to the receiving cavity 10a. Optionally, the multiple vents 13a are arranged to form a honeycomb structure.

[0041] Please refer to the attached document. Figures 1-5In this embodiment, the waterproof component 20 is disposed on the inner side of the side wall 13. The waterproof component 20 is connected to the side wall 13 and covers the vent 13a, so that the waterproof component 20 can be fixed on the inner side of the side wall 13. The waterproof component 20 forms an air duct 21, which is connected to the receiving cavity 10a and the vent 13a respectively, so that the wind from the external environment can flow to the air duct 21 through the vent 13a, thereby facilitating the second layer of filtration of the wind from the external environment by the air duct 21. This also facilitates the inner side wall 13 of the air duct 21 to block the spray water and rainwater carried by the wind from the external environment, thereby achieving the second layer of protection.

[0042] The air duct 21 is inclined toward the vent 13a so that the spray water and rainwater blocked by the inner wall 13 of the air duct 21 can flow to the vent 13a along the inclined direction, thereby facilitating the discharge of spray water and rainwater outward through the vent 13a and ensuring the smooth flow of spray water and rainwater toward the vent 13a.

[0043] Please refer to the attached document. Figures 1-5 In this embodiment, the filter cotton assembly 30 is disposed on the side of the waterproof assembly 20 facing away from the vent 13a. The filter cotton assembly 30 is connected to the waterproof assembly 20 and covers the air duct 21, so that the filter cotton assembly 30 is fixed on the side of the waterproof assembly 20 facing away from the vent 13a, so that the air from the external environment filtered by the second layer can flow to the filter cotton assembly 30, thereby facilitating the filter cotton assembly 30 to achieve the third layer of filtration of the air from the external environment, and further facilitating the filter cotton assembly 30 to block the dust carried by the air from the external environment, so as to achieve the third layer of protection.

[0044] At this time, the wind from the external environment flows through the vent 13a, the waterproof component 20, and the filter cotton component 30 to the receiving cavity 10a in sequence. This facilitates the vent 13a, the waterproof component 20, and the filter cotton component 30 to perform multi-layer filtration of the wind from the external environment, thereby achieving multi-layer protection and preventing dust, water, or foreign objects from the external environment from entering the inside of the battery cabinet 100, thus improving the protective effect of the battery cabinet 100.

[0045] Please refer to the attached document. Figure 5 The side wall 13 is also provided with a drainage cavity 13b that connects to the receiving cavity 10a. The drainage cavity 13b extends toward the bottom wall 11 and penetrates the side wall 13. The drainage cavity 13b is located below the ventilation opening 13a. The air duct 21 is also connected to the drainage cavity 13b so that the spray water and rainwater in the air duct 21 can be discharged outward along the ventilation opening 13a and the drainage cavity 13b, thereby realizing multiple outlets for spray water and rainwater and ensuring the discharge effect of spray water and rainwater.

[0046] Please refer to the attached document. Figures 1-5The waterproof component 20 includes a first waterproof structure 22 and a second waterproof structure 23. The second waterproof structure 23 is disposed on the rear side of the first waterproof structure 22. The first waterproof structure 22 is connected to the side wall 13 and covers the vent 13a. The second waterproof structure 23 is connected to the side wall 13 and covers the vent 13a, so that the first waterproof structure 22 and the second waterproof structure 23 are respectively fixed to both sides of the side wall 13. The second waterproof structure 23 is located between the first waterproof structure 22 and the filter cotton component 30, so that the first waterproof structure 22 and the second waterproof structure 23 can provide double waterproofing for the air filtered by the first layer, ensuring the waterproof effect of the waterproof component 20 relative to the air filtered by the first layer.

[0047] Please refer to the attached document. Figures 1-5 The air duct 21 includes a first air duct 211 and a second air duct 212. The first waterproof structure 22 has the first air duct 211 and the second waterproof structure 23 has the second air duct 212. The first air duct 211 is inclined toward the vent 13a so that the spray water and rainwater blocked by the first air duct 211 can flow along the inner wall 13 of the first air duct 211 to the vent 13a, thereby facilitating the spray water and rainwater in the first air duct 211 to be discharged through the vent 13a in the inclined direction under its own gravity.

[0048] The second air duct 212 is connected to the first air duct 211. The second air duct 212 is inclined toward the drainage chamber 13b so that the spray water and rainwater blocked by the second air duct 212 can flow along the inner wall 13 of the second air duct 212 to the first air duct 211 or the drainage chamber 13b. This allows the spray water and rainwater in the second air duct 212 to be discharged through the vent 13a and the drainage chamber 13b under their own gravity in the inclined direction. The first waterproof structure 22 discharges the spray water and rainwater from the vent 13a, and the second waterproof structure 23 discharges the spray water and rainwater from the vent 13a and the drainage chamber 13b.

[0049] Please refer to the attached document. Figure 6 The first waterproof structure 22 includes a first mounting frame 221 and multiple first guide plates 222. The first mounting frame 221 surrounds multiple vents 13a and is connected to the side wall 13 so that the first mounting frame 221 can be fixed to the side wall 13, thereby facilitating the connection between the first waterproof structure 22 and the side wall 13 through the first mounting frame 221. The multiple first guide plates 222 are connected to the first mounting frame 221 and spaced apart from each other to form a first air duct 211 so that the multiple first guide plates 222 can be fixed to the first mounting frame 221. The first guide plates 222 are inclined toward the vents 13a so that the spray water and rainwater blocked by the first guide plates 222 can flow to the vents 13a under the guidance, ensuring the smooth discharge of spray water and rainwater.

[0050] Please refer to the attached document. Figure 6The first guide plate 222 includes a first bent portion 2221 and a first inclined portion 2222. The first bent portion 2221 is disposed at opposite ends of the first inclined portion 2222, and an angle is formed between the first bent portion 2221 and the first inclined portion 2222. The first inclined portion 2222 is inclined toward the vent 13a, and the first bent portion 2221 extends toward the drainage chamber 13b, so that the spray water and rainwater in the first inclined portion 2222 can flow from top to bottom through the first bent portion 2221 to the drainage chamber 13b, or the spray water and rainwater in the first inclined portion 2222 can flow directly to the vent 13a, so that the spray water and rainwater can be discharged along two guiding directions.

[0051] The first guide plate 222 abuts against the part of the side wall 13 where the ventilation opening 13a is provided, so that the first bent part 2221 of the first guide plate 222 contacts the side wall 13, thereby facilitating the direct discharge of spray water and rainwater from the first guide plate 222 through the ventilation opening 13a.

[0052] Please refer to the attached document. Figure 7 The second waterproof structure 23 includes a second mounting frame 231 and a plurality of second guide plates 232. The second mounting frame 231 surrounds the plurality of ventilation openings 13a and is connected to the side wall 13 so that the second mounting frame 231 is fixed to the side wall 13, thereby facilitating the connection of the second waterproof structure 23 to the side wall 13 through the second mounting frame 231.

[0053] Multiple second guide plates 232 are connected to and spaced apart from the second mounting frame 231 to form a second air duct 212, so that the multiple second guide plates 232 are fixed to the second mounting frame 231. The second guide plates 232 are inclined toward the vent 13a so that the spray water and rainwater blocked by the second guide plates 232 can flow to the vent 13a and the drainage chamber 13b under the guidance, ensuring the smooth discharge of spray water and rainwater. The second guide plates 232 and the first waterproof structure 22 are spaced apart so that there is a gap between the second guide plates 232 and the first waterproof structure 22, so that the spray water and rainwater in the second guide plates 232 can flow to the drainage chamber 13b through the gap.

[0054] Please refer to the attached document. Figure 7 The second guide plate 232 includes a second bending portion 2321, a second inclined portion 2322, and a blocking portion 2323. The second bending portion 2321 is disposed at one end of the second inclined portion 2322 near the vent 13a, so that the second bending portion 2321 is fixed to the lower side of the second inclined portion 2322. The blocking portion 2323 is disposed at one end of the second inclined portion 2322 away from the vent 13a, so that the blocking portion 2323 is fixed to the upper side of the second inclined portion 2322.

[0055] The second inclined portion 2322 is inclined toward the vent 13a so that the spray water and rainwater in the second inclined portion 2322 can flow to the vent 13a through the first inclined portion 2222. The second bent portion 2321 extends toward the drainage chamber 13b so that the spray water and rainwater in the second inclined portion 2322 can flow to the drainage chamber 13b through the second bent portion 2321. This facilitates the spray water and rainwater in the second inclined portion 2322 to be discharged along two different outlets. The blocking portion 2323 is recessed inward in the direction away from the vent 13a to form a baffle groove so that the second guide plate 232 can block the spray water and rainwater from flowing to the filter cotton assembly 30 through the upper side of the second inclined portion 2322, thereby improving the water blocking effect of the second guide plate 232.

[0056] Please refer to the attached document. Figure 2 The filter cotton assembly 30 includes filter cotton 31 and a fixing frame 32. The fixing frame 32 is connected to the waterproof assembly 20 so that the filter cotton assembly 30 can be connected to the waterproof assembly 20 through the fixing frame 32. The filter cotton 31 is fixed to the fixing frame 32 so that the fixing frame 32 can support the filter cotton 31.

[0057] Please refer to the attached document. Figure 8 The fixed frame 32 includes a frame portion 321, a crossbeam 322, and a longitudinal beam 323. The frame portion 321 has a window 321a and a mounting groove 321b surrounding the window 321a. The crossbeam 322 and the longitudinal beam 323 are respectively connected to the frame portion 321, and the crossbeam 322 and the longitudinal beam 323 are perpendicular to each other, so that the crossbeam 322 is fixed to the frame portion 321 in the transverse direction, and the longitudinal beam 323 is fixed to the frame portion 321 in the longitudinal direction.

[0058] The edge of the filter cotton 31 is fitted into the mounting groove 321b so that the filter cotton 31 can be connected to the frame 321 through the mounting groove 321b. The filter cotton 31 covers the window 321a so that the crossbeam 322 and the longitudinal beam 323 can support the middle of the filter cotton 31. This makes it easy for the crossbeam 322 and the longitudinal beam 323 to clamp the filter cotton 31 with the outer wall 13 of the second guide plate 232, ensuring the position of the filter cotton 31 relative to the second guide plate 232 so that the filter cotton 31 can filter the air flowing through the second guide plate 232. This makes it easy for the filter cotton 31 to block the dust carried by the wind in the external environment. The filter cotton 31 can allow the wind in the external environment to pass through.

[0059] In another embodiment, an electrical system includes a battery and a battery cabinet 100. The battery is placed in the battery cabinet 100 so that it can be fixed inside the battery cabinet 100, thereby preventing dust, water or foreign objects from the external environment from coming into contact with the battery, ensuring the performance of the battery and extending its life.

[0060] The beneficial effects of this invention are as follows:

A waterproof component 20 is connected to the side wall 13 and covers the ventilation openings 13a. The waterproof component 20 forms an air duct 21, which communicates with the receiving cavity 10a. The air duct 21 is inclined toward the air duct 13a and is connected to the vent 13a. The filter cotton assembly 30 is connected to the waterproof assembly 20 and covers the air duct 21 so that the wind from the external environment flows through the vent 13a, the waterproof assembly 20 and the filter cotton assembly 30 to the receiving cavity 10a in sequence. This facilitates the air duct 13a, the waterproof assembly 20 and the filter cotton assembly 30 to filter the wind from the external environment in multiple layers, so as to achieve multi-layer protection and prevent dust, water or foreign objects from the external environment from entering the inside of the battery cabinet 100, thereby improving the protective effect of the battery cabinet 100.
