The inventor finds that in the technical field of unmanned aerial vehicles, for example, batteries on industrial application unmanned aerial vehicles and agricultural unmanned aerial vehicles generally have large capacity, batteries charged with large multiplying power are easy to explode, the batteries need to be transported to operation scenes such as farmlands through vehicles before use, and in the normal condition of transportation, the batteries are placed in the vehicles in a naked mode or in simple battery boxes, so that users cannot notice the state of the batteries easily. The risk of battery explosion is easily increased due to collision between the battery and the battery box, and once the battery explodes, the battery box also explodes, so that external inflammable matters are ignited, and life and property losses are caused.

Fig. 1 is a schematic structural diagram of a battery storage device according to an embodiment of the invention; fig. 2 is a cross-sectional view of a battery storage device according to an embodiment of the present invention; fig. 3 is an exploded view of a battery storage device according to an embodiment of the invention. Referring to fig. 1 to fig. 3, a battery storage device according to an embodiment of the present invention is configured to accommodate a battery 100, and the battery storage device includes: the casing 10, the first stopper 20, the inner box 30.

Wherein the case 10 is formed with an accommodating space for accommodating the battery 100; the first limiting member 20 is disposed in the accommodating space and used for limiting the battery 100.

The shape of the housing 10 is not limited, and may be, for example, square, circular, hexagonal, or the like. The housing 10 may include a housing bottom wall, and a housing side wall surrounding the housing bottom wall, the housing bottom wall and the housing side wall defining the accommodating space.

The first limiting member 20 may be fixed to an inner wall of the housing 10 (including an inner wall of the housing bottom wall and an inner wall of the housing side wall), and preferably, the first limiting member 20 may be adhered to the inner wall of the housing 10. Alternatively, the outer dimension of the first limiting member 20 is slightly larger than the inner dimension of the housing 10, so that the first limiting member 20 can be pressed against the inner wall of the housing 10. The first limiting member 20 may be made of a material having elasticity, and preferably, the first limiting member 20 may include a flame-retardant foaming material, for example, flame-retardant foamed polypropylene, polypropylene plastic foaming material, and the like. The first limiting members 20 in the housing 10 may include one or more first limiting members 20, when there is one first limiting member 20, a first insertion groove P1 for the battery 100 to be inserted into may be formed on the first limiting member 20, and when there are a plurality of first limiting members 20, the plurality of first limiting members 20 may be distributed and enclose a first insertion groove P1 for the battery 100 to be inserted into.

The inner box 30 is arranged in the accommodating space, and the inner box 30 is used for accommodating cooling substances; the inner box 30 has a discharge port 31, and a discharge module 32 for sealing the discharge port 31 is hermetically provided at the discharge port 31. When the temperature in the accommodating space reaches a preset value, the sealing position between the discharge module 32 and the discharge port 31 can be deformed by heat, so that the sealing between the discharge module 32 and the inner box 30 is failed, and the cooling substance can overflow.

In this embodiment, the temperature reducing substance is a substance capable of reducing the temperature in the space, and the temperature reducing substance may specifically include at least one of the following substances: water, foam extinguishing agent and carbon dioxide. The inner case 30 may be provided at the middle of the case 10, and the battery 100 may be provided between the inner case 30 and the case 10. The plurality of batteries 100 may be disposed around the inner case 30, or the plurality of batteries 100 may be located at both sides of the inner case 30.

The inner case 30 includes a bottom wall 30a and a side wall 30b that is provided around the bottom wall 30 a. Preferably, the discharge port 31 of the inner box 30 may be located at an end of the side wall 30b of the inner box 30 close to the bottom wall 30a, so that once the temperature of the accommodating space in the housing 10 is too high, the cooling substance in the inner box 30 can be discharged as much as possible, and the situation that only the cooling substance at the upper position in the inner box 30 can be discharged due to the too high position of the discharge port 31, so that the discharging amount of the cooling substance is insufficient, and the cooling effect is not good is avoided.

When the discharge port 31 is provided at one end of the side wall 30b of the inner box 30 close to the bottom wall 30a, the bottom wall 30a of the inner box 30 may be directly attached to the bottom wall of the casing 10, or the inner box 30 may be suspended in the casing 10 such that a distance is provided between the bottom wall 30a of the inner box 30 and the bottom wall of the casing 10, and the discharge port 31 is located on the bottom wall 30a of the inner box 30. This arrangement also allows the temperature reducing substance in the inner box 30 to escape as much as possible.

In addition, it is to be noted that the position of the ignition point on the battery 100 also needs to be considered when designing the position of the discharge port 31. In general, the ignition point of the battery 100 is a port of the electrical connector of the battery 100, and the exhaust port 31 may be disposed as close to the port of the electrical connector of the battery 100 as possible, so that when the ignition point of the battery 100 starts to generate a flame, the flame at the ignition point of the battery 100 can be extinguished in time, and further ignition and detonation of the battery 100 can be avoided in time.

The outlet 31 is hermetically connected to the discharging module 32, and when the temperature in the accommodating space reaches a preset value, a sealed portion between the discharging module 32 and the outlet 31 can be thermally deformed, and preferably, at least one of the inner box 30 and the discharging module 32 can be thermally deformed.

The discharge port 31 is connected with the discharge module 32 in a sealing manner, specifically, the discharge module 32 is connected with the discharge port 31 in a threaded manner, the discharge module 32 is sealed with the discharge port 31 by a sealing ring, and the discharge module 32 is connected with the discharge port 31 in a threaded manner, so that the structure is simple and reliable, and the operation is convenient. Of course, in other embodiments, the bleeder module 32 and the discharge port 31 may be connected by an interference fit or other methods, and the invention is not limited in particular.

It can be understood that the sealing between the bleeder module 32 and the discharge port 31 can be deformed by heat, which includes the following ways: the seal ring and the inner case 30 can be thermally deformed; alternatively, the sealing ring and the drain module 32 may be thermally deformed. In some embodiments, only the seal ring may be heat deformable. The solutions provided in the above description for thermal deformation of the sealing portion between the discharging module 32 and the discharging port 31 can all achieve the sealing failure between the discharging module 32 and the discharging port 31.

In the present embodiment, the inner case 30 is preferably a plastic member, and the inner case 30 may be made of a material having a heat distortion temperature lower than 90 °, for example, PET (polyester resin). When the inner case 30 can be thermally deformed, the temperature reducing substance in the inner case 30 can be discharged most quickly than in the other two ways.

According to the battery storage device provided by the embodiment of the invention, the first limiting part is arranged in the accommodating space of the shell to limit the battery, so that the collision of the battery in the shell is buffered, the risk of the collision of the battery in the shell is effectively reduced, the inner box containing the cooling substance is arranged in the shell containing the battery, the inner box is provided with the discharge port, the discharge port is provided with the discharge module, after the temperature in the accommodating space reaches the preset value, the sealing between the discharge port and the discharge module is invalid, the cooling substance can overflow, so that the temperature in the accommodating space is reduced, and the risk of explosion of the battery and the battery box is effectively and reliably reduced.

Fig. 4 is a perspective cross-sectional view of an inner case in the battery storage device according to an embodiment of the present invention; as shown in fig. 4, the inner case 30 includes an injection port 33, and the injection port 33 allows a temperature lowering substance to be injected into the inner case 30. Specifically, the injection port 33 may be cylindrical and protrude from the surface of the inner box 30, the injection port 33 may be provided with an injection port cover 331, the injection port cover 331 may be screwed into the injection port 33 in a threaded manner, and the injection port cover 331 may also be connected to the injection port 33 in a sealing manner. By providing the inlet cap 331, the inlet 33 can be effectively sealed when the cooling material is not required to be injected, and the cooling material in the inner case 30 is prevented from overflowing or splashing out of the inlet 33 during transportation of the battery storage device.

Further, the injection port 33 may be located at the top of the inner case 30 to enable the inner case 30 to have the maximum capacity. Of course, it is not excluded that in other embodiments, the injection port 33 may be located elsewhere in the inner box 30.

In this embodiment, the inner case 30 may preferably include plastic members, and the drain module 32 may include metal members. The inner case 30 includes plastic members, so that when the temperature in the accommodating space is increased due to the combustion of the battery 100, the inner case 30 can be thermally deformed in time, and the sealing between the discharge port 31 and the discharge module 32 of the inner case 30 is disabled, so that the cooling material can be discharged into the accommodating space relatively quickly.

Alternatively, the inner box 30 may also comprise metal and the drain module 32 may also comprise plastic. The discharging module 32 includes a plastic member, so that when the temperature in the accommodating space is increased due to the combustion of the battery 100, the discharging module 32 can be thermally deformed in time, so that the sealing between the discharging port 31 of the inner case 30 and the discharging module 32 is disabled, and the cooling material can be discharged into the accommodating space.

As shown in fig. 4, the outlet 31 may be cylindrical and protrude from the side wall of the inner box 30. The cylindrical discharge port 31 can facilitate the installation of the discharge module 32. In the embodiment shown in fig. 4, the discharge module 32 may be a cover, which may be sleeved on the outer side of the cylindrical discharge port 31, specifically, the outer side of the cylindrical discharge port 31 may have an external thread, and the inner side of the cover may have an internal thread, which are connected by a thread. The discharging module 32 is directly a cover, and has simple structure and low manufacturing cost.

In addition, preferably, the discharge ports 31 may be two or more, two discharge ports 31 may be symmetrically provided in the inner case 30, or a plurality of discharge ports 31 may be uniformly arranged in the inner case 30, so that the temperature reduction process of the plurality of batteries 100 uniformly and dispersedly arranged can be realized.

In the present embodiment, another structure of the leaking module 32 is provided, specifically, referring to fig. 5 to 10, when the inner box 30 includes a metal part and the leaking module 32 includes a plastic part; the discharge module 32 includes a cylinder 321, a cap 322, and a piston 323.

The cylindrical body 321 is hermetically fixed to the discharge port 31, and a through hole 3211 is formed in a side wall of the cylindrical body 321. Specifically, as shown in fig. 5, the cylinder 321 may be sleeved outside the cylindrical discharge port 31, and the cylinder 321 and the discharge port 31 may be screwed together, and the cylinder 321 and the discharge port 31 may be end-sealed by a first sealing ring X1, and more specifically, the cylinder 321 may include a large hole section 321a and a small hole section 321b, a step 321c is formed at a joint of the large hole section 321a and the small hole section 321b, and the first sealing ring X1 may be disposed on the step.

Specifically, as shown in fig. 7 to 10, the blocking cover 322 may be sleeved outside the small hole section 321b of the cylinder 321, and the blocking cover 322 and the cylinder 321 may be sealed by an end face of a second sealing ring X2. Preferably, the cap 322 may be a plastic part, and the barrel 321 may be a metal part, however, in other embodiments, the cap 322 may be a metal part, and the barrel 321 may be a plastic part. It is sufficient that, when the temperature in the accommodating space increases to a predetermined value due to spontaneous combustion of the battery 100, the cap 322 or the barrel 321 melts to disable the seal therebetween, that is, the seal at the seal between the escape module 32 and the inner case 30.

The piston 323 is movably provided in the cylinder 321, and the piston 323 can move from a position of closing the through hole 3211 to a position of avoiding the through hole 3211, and when the piston 323 is at the position of avoiding the through hole 3211, the temperature reducing substance in the inner casing 30 can escape from the through hole 3211. The piston 323 can be in sealing contact with the inner wall of the cylinder 321, so that a closed space can be formed between the piston 323, the cylinder 321, and the cap 322.

As shown in fig. 7 and 8, in the initial state, the piston 323 can be positioned at a position where the through hole 3211 of the cylinder 321 is closed, the closed space formed by the piston 323, the cylinder 321, and the closing cap 322 is filled with air, the piston 323 cannot move toward the end of the closing cap 322, the through hole 3211 of the cylinder 321 is blocked, and the cooling material cannot flow out from the through hole 3211 of the cylinder 321.

As shown in fig. 9 and 10, when the plug 322 is made of plastic, when the battery 100 in the accommodating space spontaneously ignites, the plug 322 is deformed by heat and melted, the seal between the plug 322 and the cylinder 321 is lost, air escapes, the pressure in the space between the piston 323, the plug 322 and the cylinder 321 is reduced, the piston 323 moves towards the end of the plug 322, and the cooling material in the inner box 30 flows out from the through hole 3211 of the cylinder 321.

Similarly, when the cylinder 321 is made of plastic, when the battery 100 in the accommodating space is spontaneously ignited, the cylinder 321 may be heated, deformed and melted, the sealing between the cap 322 and the cylinder 321 is lost, air escapes, the pressure in the space between the piston 323, the cap 322 and the cylinder 321 is reduced, the piston 323 moves toward the end of the cap 322, and the cooling material in the inner box 30 flows out from the through hole 3211 of the cylinder 321.

The piston 323 can be switched to a position where the through hole 3211 is opened at a position where the through hole 3211 is closed. Specifically, the piston 323 divides the cylinder 321 into a first chamber C1 and a second chamber C2 which are isolated from each other, the first chamber C1 is located between the blocking cover 322 and the piston 323, and the second chamber C2 is communicated with the inner box 30; when the temperature in the accommodating space reaches a preset value, the discharge module 32 can be thermally deformed to disable the sealing of the first chamber C1, and the pressure of the second chamber C2 pushes the piston 323 to move to a position avoiding the through hole 3211, so that the cooling material in the inner box 30 is discharged from the through hole 3211.

Since the second chamber C2 is communicated with the inner box 30, when the first chamber C1 fails to seal due to thermal deformation, the air in the first chamber C1 escapes, the pressure in the first chamber C1 and the second chamber C2 is unbalanced, the air in the second chamber C2 pushes the piston 323 together with the cooling material, and the piston 323 moves to open the through hole 3211 against the frictional resistance with the cylinder 321.

The battery storage device provided by the embodiment of the invention can rapidly spray the cooling substance when the battery 100 is spontaneously combusted, so that the accommodating space where the battery 100 is positioned is rapidly cooled, and the situation that the temperature in the accommodating space is too high to explode so as to influence the safety of lives and properties is prevented.

Further, on the basis of any of the above embodiments, the number of the batteries 100 in the accommodating space is at least two, and at least two batteries 100 may be symmetrically or uniformly distributed around the inner case 30. Accommodating at least two batteries 100, even a plurality of batteries 100, in the accommodating space defined by the housing 10 can improve the carrying efficiency of the batteries 100 of the agricultural drone. And at least two batteries 100 are symmetrically or uniformly distributed around the inner box 30, so that the balance of weight distribution of the battery storage device can be improved, the stress of the battery storage device is balanced as much as possible in the process of loading and carrying the batteries 100, and the stability of the battery storage device in the carrying process is improved.

The number of the inner cases 30 is at least two, and the at least two inner cases 30 are collectively disposed in the middle of the casing 10. Specifically, at least two inner boxes 30 can be intensively arranged in the middle of the housing 10, and at least two batteries 100 can be arranged between the inner boxes 30 and the housing 10, the layout is reasonable and compact, the space utilization rate is high, and at least two inner boxes 30 are intensively arranged in the middle of the housing 10, so that when the temperature in the accommodating space is too high due to spontaneous combustion of any battery 100 in the accommodating space, the cooling substance in the inner boxes 30 can be dispersed to the spontaneous combustion part of the battery 100 through the shortest path after overflowing.

The two batteries 100 inside the battery storage device can be separated from each other by the first limiting member 20 and the inner case 30, and when one of the batteries 100 self-ignites, the heat source can be effectively isolated by the first limiting member 20 and the inner case 30, so that the other battery 100 is prevented from being ignited.

Further, the battery 100 may include an electrical connector port (not shown in the drawings), and the discharge port 31 of the inner case 30 may be located below the electrical connector port in a state where the battery 100 and the inner case 30 are respectively received in predetermined positions of the receiving space. Specifically, the electrical connector port may be used to be electrically connected to an external charging device to charge the battery 100, or the electrical connector port may be used to be connected to an external device to supply power to the external device, or the electrical connector port may be used to be electrically connected to an external device to implement data transmission, which is not limited in this embodiment.

In this embodiment, the discharge port 31 is preferably disposed below the port of the electrical connector, since the battery 100 is sealed, and only the port of the electrical connector is communicated with the outside, when the battery 100 is spontaneously combusted, the internal flame and high-temperature smoke are discharged through the port of the electrical connector, and thus the discharge module 32 is easily triggered due to high temperature, which is beneficial to timely overflow of the cooling substance.

As described in detail below with respect to the specific shape and structure of the first limiting member 20, as shown in fig. 3, the first limiting member 20 is substantially shaped like a Chinese character 'ji' or a Chinese character 'shan'. This kind of structure can effectively ensure that battery 100 is restrained in "how font" or "chevron" first locating part 20. Of course, in some other embodiments, the shape of the first limiting member 20 may also be other shapes, and the embodiment is not limited thereto.

In some embodiments, a first slot P1 for limiting the battery 100 is formed on the first limiting member 20; when the battery 100 is inserted into the first insertion slot, a port of the electrical connector of the battery 100 (not shown in fig. 2 and 3) faces a side facing away from the case 10, whereby, when the battery 100 is ignited by spontaneous combustion, the port of the electrical connector of the battery 100 is ignited, flame faces the center of the case 10 without being outwardly sprayed, so as to avoid ignition of external inflammable substances.

Fig. 11 is a schematic structural diagram of a battery storage device according to yet another embodiment of the invention; fig. 12 is a schematic view of the internal structure of a battery storage device according to another embodiment of the present invention when a battery is not mounted; fig. 13 is a schematic diagram of an internal structure of a battery storage device according to another embodiment of the present invention after a battery is installed in the battery storage device. As shown in fig. 11 to 13, in other embodiments, when the battery 100 is inserted into the first slot P1, the port 101 of the electrical connector of the battery 100 faces one side of the housing 10.

When the battery 100 is inserted into the first slot P1, the port of the electrical connector of the battery 100 faces one side of the case 10, and the port of the electrical connector of the battery 100 is exposed from the case 10. Therefore, when the battery 100 is enclosed in the housing 10, the battery 100 can be charged through the exposed port of the electrical connector, and particularly, the battery 100 can be charged during transportation of the battery 100 without taking the battery 100 out of the battery storage device, thereby improving the charging efficiency of the battery 100.

More specifically, the port 101 of the electrical connector of the battery 100 may be located at the top of the battery 100, and in other embodiments, the port 101 of the electrical connector of the battery 100 may be located at the side of the battery 100.

As shown in fig. 3, further, the first limiting member 20 may include a protruding portion 21, and the first slots P1 include an even number, and the even number of the first slots P1 is symmetrical to the protruding portion 21. Since the first insertion grooves P1 are used for inserting the batteries 100 to limit the position of the batteries 100, the number and position of the first insertion grooves P1 determine the number and position of the batteries 100, and thus, an even number of batteries 100 can be arranged symmetrically to the protrusions 21.

Further, the first limiting member 20 further has a second slot P2 for the inner box 30 to be inserted into. The inner case 30 is inserted into the second slot P2 to restrain the inner case 30. Specifically, the second slot P2 may be located at the protruding portion 21, and the inner case 30 is provided at the protruding portion 21, whereby the battery 100 may be arranged symmetrically to the inner case 30.

On the basis of the above embodiment, specifically, when the battery 100 is inserted into the first slot P1, the port of the electrical connector of the battery 100 may face the protruding portion 21.
