[0043] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0044] In the present disclosure, unless otherwise specified, "inside" and "outside" refer to the inside and outside of the contour of the corresponding component. Furthermore, the terms "first" and "second" used in the present disclosure are to distinguish one element from another and have no order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0045] according to Figures 1 to 12 As shown, an embodiment of the present disclosure provides an air battery, which may include a case 1, a partition 2, a working fluid tank 6, a fuel cell stack 4 and a circulation pipeline 3. A first storage space 11 and a second storage space 13 may be provided in the case 1. The partition 2 may be provided in the first storage space 11, and is used to separate the first storage space 11 into a first chamber 110 and a second chamber 111 spaced along a horizontal first direction X. The working fluid tank 6 may be provided in the second storage space 13, and the fuel cell stack 4 may be removably provided in the second chamber 111. The circulation pipeline 3 is connected between the working fluid tank 6 and the fuel cell stack 4. The circulation pipeline 3 extends from the first chamber 110 to the second storage space 13 to be connected to the working fluid tank 6. The circulation pipeline 3 passes through the partition 2 from the first chamber 110 and is detachably connected to the fuel cell stack 4 through a fluid connector.

[0046] Through the above technical solution, a partition 2 is provided to separate the first accommodating space 11 into a first chamber 110 and a second chamber 111, so that the battery stack 4 and the circulation pipeline 3 are arranged at intervals through the partition 2, which is more regular and concise, so that the operator can quickly inspect and maintain the battery stack 4 or the circulation pipeline 3, and it is convenient to find the fault point. The battery stack 4 is removably arranged in the second chamber 111, and the circulation pipeline 3 is detachably connected to the battery stack 4 through a fluid connector, which can realize the rapid disassembly and installation of the battery stack 4, which is more convenient and more reliable to use.

[0047] Among them, the second accommodating space 13 can be arranged below the first accommodating space 11, or the second accommodating space 13 can also be arranged side by side with the first accommodating space 11, or the second accommodating space 13 can also be arranged above the first accommodating space 11. The present disclosure is not limited to this, and those skilled in the art can make adaptive adjustments according to the needs of actual conditions.

[0048] The air battery may further include a third storage space 12, which is used to store the intermediate liquid tank 7, which is used to replenish the electrolyte to the working liquid tank 6. The third storage space 12 may be arranged side by side with the first storage space 11, and the second storage space 13 may be arranged below the first storage space 11 and the third storage space 12, so that the intermediate liquid tank 7 replenishes the electrolyte to the working liquid tank 6. Of course, the third storage space 12 may also be arranged side by side with the second storage space 13. The present disclosure is not limited thereto.

[0049] In some possible implementations, for example, referring to Figure 2 , Figure 5 , Figure 6 and Fig.10As shown, the second chamber 111 may have a take-in and take-out port opposite to the partition 2 along the first direction X, and the box body 1 may include a second box door 10 for closing or opening the take-in and take-out port, so as to facilitate the installation and disassembly of the battery stack 4 by opening the second box door 10. A guide structure 5 may be provided in the second chamber 111, and the guide structure 5 is used to guide the battery stack 4 to move along the first direction X so as to be connected to the circulation pipeline 3 through the fluid connector, so that the operator can quickly install and disassemble the battery stack through the guide structure 5, avoid the battery stack 4 from being offset during the displacement process of installation and disassembly, and have greater safety and reliability in use.

[0050] Among them, the second box door 10 may include a first side door 101 and a second side door 102 arranged adjacent to each other along the second direction Y. A display panel 8 may be provided on the first side door 101. For example, the display panel 8 may adopt a human-computer interaction panel for displaying information such as the current and voltage of the air battery, the temperature of the electrolyte, the protection temperature, the power and the usage time, so that the operator can monitor the status of the air battery in real time, so that the operator can detect and perform targeted maintenance in time when a certain group of battery stacks 4 fails.

[0051] Optionally, the first chamber 110 may have a maintenance port opposite to the partition 2, and the box body 1 may further include a first door 14 for closing or opening the maintenance port, so that the operator can repair the circulation pipeline 3 in the first chamber 110. The first door 14 and the second door 10 are arranged opposite to each other, so that the operator can perform maintenance.

[0052] In some possible implementations, for example, referring to Figure 2 , Figure 8 and Fig. 9 As shown, handles 43 may be provided on both sides of the battery stack 4 opposite to each other along the first direction X to facilitate the operator to pick up and carry it, and a clearance opening 20 for avoiding adjacent handles 43 is provided on the partition 2 to prevent the handles 43 from colliding with the partition 2, resulting in the battery stack 4 and the circulation pipeline 3 being unable to dock smoothly, and also to reduce the extra space occupied by the handles 43 when there is no clearance opening 20, thereby improving space utilization and integration.

[0053] It can be understood that the handle 43 arranged on the side of the battery stack 4 facing away from the partition 2 can facilitate the operator to pull and disassemble, and the handle 43 arranged on the side of the battery stack 4 facing the partition 2 allows the operator to lift the battery stack through the two handles 43.

[0054] In some possible implementations, for example, referring to Figure 2 , Figure 4 , Figure 6 , Figure 7 , Fig. 9 , Fig.11 and Fig.12As shown, the circulation pipeline 3 may include an inlet pipeline 30 for conveying electrolyte from the working liquid tank 6 to the battery stack 4 and an outlet pipeline 31 for conveying electrolyte from the battery stack 4 to the working liquid tank 6. The fluid connector may include a first fluid connector arranged between the inlet pipeline 30 and the battery stack 4 and a second fluid connector arranged between the outlet pipeline 31 and the battery stack 4. The avoidance port 20 and the adjacent handle 43 are both located between the first fluid connector and the second fluid connector. For example, the first fluid connector and the second fluid connector may be arranged at intervals in the vertical direction. By arranging the avoidance port 20 and the adjacent handle 43 between the first fluid connector and the second fluid connector, the arrangement of the pipeline interface, handle 43, inlet pipeline 30 and outlet pipeline 31 of the battery stack 4 can be made more regular and orderly. If there are multiple battery stacks 4, and the inlet pipeline 30 or the outlet pipeline 31 of one of the battery stacks fails, it is convenient for the operator to quickly find the fault point and repair it in time.

[0055] Optionally, the first fluid connector may include a first mating portion 300 disposed on the partition 2 and a third mating portion 400 disposed on the battery stack 4, the second fluid connector may include a second mating portion 310 disposed on the partition 2 and a fourth mating portion 410 disposed on the battery stack 4, the avoidance opening 20 is disposed between the first mating portion 300 and the second mating portion 310, and the adjacent handle 43 is disposed between the third mating portion 400 and the fourth mating portion 410. By disposing the first mating portion 300 and the second mating portion 310 on the partition 2, the extension direction of the liquid inlet pipeline 30 and the liquid outlet pipeline 31 can be guided, and the arrangement is more concise. When the operator disassembles the battery stack 4, the liquid inlet pipeline 30 and the liquid outlet pipeline 31 can still be connected to the partition through the first mating portion 300 and the second mating portion 310, so as to facilitate the rapid installation of the battery stack 4.

[0056] Of course, the handle 43 of the battery stack 4 adjacent to the third matching portion 400 and the fourth matching portion 410 may also be arranged above or below the third matching portion 400 and the fourth matching portion 410 in the vertical direction. This disclosure does not specifically limit this.

[0057] The structures of the first matching portion 300 and the third matching portion 400 and the structures of the second matching portion 310 and the fourth matching portion 410 can be adaptively adjusted according to the actual needs. For example, one of the first matching portion 300 and the third matching portion 400 can be configured as a lock head, and the other can be configured as a lock seat, and one of the second matching portion 310 and the fourth matching portion 410 can be configured as a lock head, and the other can be configured as a lock seat. The present disclosure is not limited thereto.

[0058] Optionally, both the first fluid connector and the second fluid connector can be constructed as a flat sealing joint, so that when the battery stack 4 is separated from the circulation pipeline 3, the first fluid connector can automatically seal the liquid inlet of the battery stack 4 and the liquid outlet of the liquid inlet pipeline 30, and the second fluid connector can automatically seal the liquid outlet of the battery stack 4 and the liquid inlet of the liquid outlet pipeline 31 to prevent the electrolyte from flowing out, which is safer and more reliable to use. And by using a flat sealing joint, the circulation pipeline 3 and the battery stack 4 can be quickly connected, and during installation, it can be quickly installed by blind plugging, which effectively improves the installation efficiency.

[0059] Among them, one of the first fluid connector and the second fluid connector can be configured as a plane sealing joint, and the other can be configured as a valve to close the pipeline instead of a plane sealing joint. The present disclosure is not limited thereto, and those skilled in the art can make adaptive adjustments according to actual needs.

[0060] In some possible implementations, for example, referring to Figure 5 , Figure 6 , Fig. 9 and Fig.10 As shown, the second chamber 111 can be divided into a plurality of sub-chambers 1111 arranged at intervals along the vertical direction by a plurality of support plates 1110, and a plurality of battery stacks 4 arranged at intervals along the horizontal second direction Y are arranged in each sub-chamber 1111, and the battery stacks 4 are arranged one by one with the guide structure 5. By setting up a plurality of battery stacks 4, the power supply capacity can be further improved, and the power supply requirements in different situations can be better met, and the number of battery stacks 4 can be flexibly adjusted according to the power supply needs, which is more operable. And by setting up the guide structure 5, it is convenient to make the battery stack 4 and the circulation pipeline 3 accurately docked, and blind insertion can be achieved, thereby improving the efficiency of disassembly and assembly.

[0061] Optionally, the guide structure 5 may include two slide rails arranged at intervals along the horizontal second direction Y, both of which may extend along the first direction X, the battery stack 4 is slidably connected to the two slide rails along the first direction X and is limited to the two slide rails along the second direction Y; guide surfaces 50 may be provided on both opposite sides of the two slide rails, the two guide surfaces 50 extend obliquely from bottom to top and away from each other, and the battery stack 4 may be provided with two mating surfaces 42 that slidably cooperate with the two guide surfaces 50. Through the cooperation between the two guide surfaces 50 and the two mating surfaces 42, the sliding cooperation between the slide rail and the battery stack 4 can be enhanced, and the stability of the sliding process can be enhanced. In addition, the fit between the battery stack 4 and the two slide rails can better achieve the limitation of the battery stack 4 in the second direction Y.

[0062] The number of the slide rails can be adaptively adjusted according to actual needs. For example, the number of the slide rails can be one or four. The present disclosure is not limited thereto.

[0063] The guide structure 5 and the battery stack 4 may be constructed in any suitable manner. For example, the guide structure 5 may further include two slide grooves spaced apart along the horizontal second direction Y, and the battery stack 4 may further be provided with a pulley or a slider that cooperates with the two slide grooves. The present disclosure is not limited thereto.

[0064] In some possible implementations, for example, referring to Figure 4 , Figure 5 , Figure 6 , Fig.11 and Fig.12 As shown, the circulation pipeline 3 may include an inlet pipeline 30 for conveying electrolyte from the working liquid tank 6 to the battery stack 4 and an outlet pipeline 31 for conveying electrolyte from the battery stack 4 to the working liquid tank 6. The multiple battery stacks 4 in each sub-chamber 1111 are connected to the working liquid tank 6 through the same inlet pipeline 30 and the same outlet pipeline 31. The inlet pipeline 30 includes a first horizontal pipe section 301 extending along the second direction Y, and the outlet pipeline 31 includes a second horizontal pipe section 311 extending along the second direction Y. The multiple battery stacks 4 in the same sub-chamber 1111 are respectively connected to the first horizontal pipe section 301 and the second horizontal pipe section 311 through a fluid connector. Through this arrangement, the multiple battery stacks 4 in each sub-chamber 1111 can realize the delivery and discharge of electrolyte through only one inlet pipeline 30 and one outlet pipeline 31, reducing the number of inlet pipelines 30 and outlet pipelines 31, which is simpler and more convenient.

[0065] The number of the battery stacks 4 can be adaptively adjusted according to the actual needs. For example, the battery stacks 4 can be divided into multiple groups along the vertical direction according to the number of sub-chambers 1111. For example, when the number of sub-chambers 1111 is seven, the battery stacks 4 can be divided into seven groups, and the number of battery stacks 4 in each group can be four. The four battery stacks 4 are arranged in the sub-chambers 1111 at intervals along the second horizontal direction Y. The present disclosure is not limited to this.
