[0043] The battery pack 100 applicable to a flying device proposed by the present utility model is described by taking a flying car as an example. It is easy for those skilled in the art to understand that, in order to apply the relevant designs of the present utility model to other types of flying devices, various modifications, additions, substitutions, deletions, or other changes are made to the following specific implementation manners, and these changes are still within the scope of the principle of the battery pack 100 applicable to a flying device proposed by the present utility model.

[0044] As Figures 1 to 7 shownFigure 1 FIG. Figure 1 shows a perspective view of the battery pack 100 proposed by the present utility model and applicable to a flight device; Figure 2 FIG. Figure 2 shows an exploded perspective view of the battery pack 100 applicable to a flight device; Figure 3 FIG. Figure 3 shows a bottom view of the battery pack 100 applicable to a flight device; Figure 4 As shown in Figure 3 FIG. Figure 3 , a cross-sectional view taken along the straight line A-A in Figure 5 is shown; Figure 4 FIG. Figure 4 shows an enlarged view of part B in

[0045] As Figures 1 to 5 shown, in an embodiment of the present utility model, the battery pack 100 proposed by the present utility model and applicable to a flight device includes a battery box body 110 and a battery 120. The battery 120 is disposed in the battery box body 110. The battery box body 110 has a top plate, a bottom plate 111, and a plurality of side plates 112 connected between the bottom plate 111 and the bottom plate 111. The battery box body 110 is mounted on the flight device via the top plate. For example, when the flight device is a flying car, the battery box body 110 is mounted on the bottom of the body 200 of the flying car via the top plate. Among them, the bottom plate 111 is provided with a first through hole 1111. The material of the shell of the battery 120 is metal. The shell has a top wall, a bottom wall, and a side wall 121 connected between the top wall and the bottom wall. The top wall and the bottom wall face the top plate and the bottom plate 111 respectively, and a bottom wall portion of the shell of the battery 120 is exposed in the first through hole 1111. On this basis, a blocking member (such as Figure 5 the first blocking member 131 shown in FIG. Figure 5 ) is provided in the battery box body 110. The blocking member is used to block the outside air from entering the gap between two adjacent batteries 120 through the first through hole 1111. Through the above structural design, the present utility model can utilize the through hole to realize the heat exchange between the outside air flow and the battery 120, thereby improving the heat exchange performance of the battery pack. On this basis, the present utility model can utilize the blocking member to block the outside air, avoid the condensation phenomenon on the shell of the battery 120 caused by the water vapor therein, avoid short circuit, and ensure the insulation and corrosion resistance of the battery pack.

[0046] It should be noted that in some embodiments of the present utility model, taking the flying device as a flying car as an example, the battery box 110 can also be installed on the top of the body 200 of the flying car through its bottom plate 111. At this time, the first through hole 1111 can be opened on the top plate of the battery box 110. In other words, in various possible embodiments that conform to the design concept of the present utility model, the battery box 110 is installed on the flying device through one of the top plate and the bottom plate 111, and the other of the top plate and the bottom plate 111 is provided with the first through hole 1111, and a part of the battery 120 is exposed through the first through hole 1111. The blocking member is used to block the outside air from entering the gap between two adjacent batteries 120 through the first through hole 1111.

[0047] It should be noted that taking the bottom plate 111 being provided with the first through hole 1111 as an example, at this time, the top plate of the battery box 110 and the body 200 of the flying car may not have a direct connection relationship. For example, it can be connected to the bottom of the body 200 through other connection structures via the side wall of the battery box 110. In some embodiments, when the first through hole is provided on the top plate, the bottom plate 111 of the battery box 110 and the body 200 of the flying car may not have a direct connection relationship. For example, it can be connected to the top of the body 200 through other connection structures (such as a hoisting structure, etc.) via the side wall of the battery box 110. In other words, in various possible embodiments that conform to the design concept of the present utility model, one of the top plate and the bottom plate 111 faces the flying device, and the other of the top plate and the bottom plate 111 (i.e., the one facing away from the flying device) is provided with the first through hole. On this basis, the battery box 110 is installed on the flying device, but it does not limit at which position of the battery box 110 and through what connection structure it is installed on the flying device.

[0048] As Figure 5 shown, in an embodiment of the present utility model, the blocking member may include a first blocking member 131, and the first blocking member 131 can be at least partially disposed between two adjacent batteries 120. Through the above structural design, the present utility model utilizes the first blocking member 131 to occupy the gap G between two adjacent batteries 120, thereby realizing the blocking of the gap G. In addition, the present utility model can utilize the first blocking member 131 to provide a buffering function between two adjacent batteries 120, further improving the structural stability of the battery pack.

[0049] As Figure 5 shown, in an embodiment of the present utility model, the first blocking member 131 can fill the gap G between two adjacent batteries 120. Through the above structural design, the present utility model can utilize the blocking member 130 to completely occupy the gap G, thereby fundamentally eliminating the possibility of outside air entering the gap G, and further ensuring the insulation and corrosion resistance.

[0050] In one embodiment of the present invention, for the batteries 120 located at the edge of the entire array, a first blocking member 131 may also be provided between these batteries 120 and the side plate 112 of the battery box 110. Accordingly, the present invention uses the first blocking member 131 to occupy the gap between the battery 120 and the side plate 112, thereby achieving the blocking of the above-mentioned gap, and preventing the outside air from entering the gap between the battery 120 and the side plate 112 through the first through hole 1111. In addition, the present invention can use the first blocking member 131 to provide a buffer function between the battery 120 and the side plate 112, further improving the structural stability of the battery pack.

[0051] In one embodiment of the present invention, the first blocking member 131 may be a potting glue layer. For example, the first blocking member 131 may be formed by curing the potting glue. Through the above structural design, the present invention uses the first blocking member 131 to ensure insulation and corrosion resistance, and can use the potting glue layer to bond adjacent batteries 120 or batteries 120 and the box body into a whole, thereby improving the connection strength.

[0052] See also Figure 6 , Figure 6 A partial cross-sectional enlarged view of a battery pack in another exemplary embodiment that can embody the principle of the utility model is representatively shown in FIG. The specific cross-sectional angle and enlarged area can be referred to in Figure 4 Of Figure 3 The cutting angle and Figure 5 Of Figure 4 magnified area.

[0053] Different from Figure 5 The embodiment shown adopts a structural design in which the first blocking member 131 fills the gap G, such as Figure 6 As shown, in one embodiment of the utility model, the first blocking member 131 can be located in a partial area of ​​the gap G between two adjacent batteries 120 close to the first through hole 1111. In other words, the relative arrangement direction of the top plate and the bottom plate 111 is defined as the first direction X. In the first direction X, the first blocking member 131 is only located on one side of the gap to be blocked close to the first through hole 1111, that is, close to the air inlet side of the outside air. Through the above structural design, the utility model can reduce the material usage of the first blocking member 131 and reduce the material cost while ensuring the insulation and corrosion resistance performance, and can also reduce the weight of the battery pack, which is conducive to lightweight design and energy density improvement.

[0054] In addition, when a first blocking member 131 is also provided between the battery 120 located at the edge and the side plate 112 of the battery box 110 , the first blocking member 131 may be located in a partial area of ​​the gap between the battery 120 and the side plate 112 close to the first through hole 1111 .

[0055] Refer to Figure 7 , Figure 7 which shows a partially sectional enlarged view of a battery pack that can embody the principle of the present utility model in another exemplary embodiment. The specific cutting angle and enlarged area can be referred to Figure 4 with respect to Figure 3 the cutting angle of Figure 5 and with respect to Figure 4 the enlarged area of

[0056] As Figure 7 shown, in an embodiment of the present utility model, the sealing member may further include a second sealing member 132. The second sealing member 132 may be at least partially disposed between the bottom plate 111 and the battery 120 (such as the bottom wall of the housing), and the second sealing member 132 is arranged to surround the first through hole 1111 in a sealed and continuous manner. Through the above structural design, on the basis of ensuring the insulation and corrosion resistance performance, the present utility model can utilize the second sealing member 132 to realize the protection function for the bottom of the battery 120 and improve the anti-ball impact ability of the battery pack.

[0057] As Figure 7 shown, based on the structural design that the second sealing member 132 is disposed between the bottom plate 111 and the battery 120, in an embodiment of the present utility model, the second sealing member 132 may be a layered structure, and the second sealing member 132 is disposed on the side of the bottom plate 111 facing the battery 120. On this basis, the above layered structure covers all areas of at least a part of the bottom wall 122 of the battery 120. The above layered structure is provided with a second through hole 1321, and the second through hole 1321 is arranged corresponding to the position of the first through hole 1111. For example, when the battery pack includes a plurality of batteries 120 and the first through holes 1111 are multiple and correspond to the plurality of batteries 120 one by one, the second sealing member 132 in the form of a layered structure may cover all areas of the bottom walls 122 (or top walls 121) of all the batteries 120, or may also cover all areas of the bottom walls 122 (or top walls 121) of one or at least two batteries 120. Moreover, the number and position of the first through holes 1111 corresponding to the layered structure also determine the number and position of the second through holes 1321 to be opened in the layered structure, so as to realize surrounding the first through holes 1111 respectively in a sealed and continuous manner. Through the above structural design, the present utility model can utilize the second sealing member 132 to seal the area of the bottom of the battery 120 except for the area corresponding to the first through hole 1111, thereby blocking the outside air from entering the above-mentioned gap.

[0058] In an embodiment of the present utility model, the second sealing member 132 may be a gasket. Through the above structural design, the present utility model can make the forming of the second sealing member 132 more convenient and accurate, facilitate the precise alignment of various structures such as the first through hole 1111, and ensure the sealing performance.

[0059] Refer to Figure 8 , Figure 8 which shows a partially sectional enlarged view of a battery pack that can embody the principle of the present utility model in another exemplary embodiment. The specific cutting angle and enlarged area can be referred to Figure 4 for Figure 3 the cutting angle and Figure 5 for Figure 4 the enlarged area.

[0060] Different from Figure 7 the structural design in the shown embodiment where the second sealing member 132 has a layered structure. As Figure 8 shown, still taking the sealing member including the second sealing member 132 disposed between the bottom plate 111 and the battery 120 as an example, the second sealing member 132 can be an annular structure, and the second sealing member 132 is disposed on the side of the bottom plate 111 facing the battery 120. The above annular structure is arranged around the outer periphery of the orifice on the side of the first through hole 1111 facing the battery 120. In other words, the second sealing member 132 in this embodiment forms a structure similar to a "sealing ring". Through the above structural design, on the basis of ensuring insulation and corrosion resistance, the present utility model can reduce the material usage of the second sealing member 132, reduce the material cost, and reduce the weight of the battery pack, which is beneficial to lightweight design and improvement of energy density.

[0061] It should be understood that according to different design requirements and the structural characteristics of the battery pack, the above Figures 5 to 8 shown multiple embodiments can be implemented separately or in combination. For example, the sealing member can include both the first sealing member 131 and the second sealing member 132 at the same time. Another example is that for multiple such gaps at different positions, some gaps can be filled by the sealing member, and some gaps can be partially occupied by the sealing member, all not limited to the above embodiments.

[0062] Refer to Figure 9 , Figure 9 which shows a partially sectional enlarged view of a battery pack that can embody the principle of the present utility model in another exemplary embodiment. The specific cutting angle and enlarged area can be referred to Figure 4 for Figure 3 the cutting angle and Figure 5 for Figure 4 the enlarged area.

[0063] Such as Figure 9As shown, in an embodiment of the present invention, the sealing member may simultaneously include a first sealing member 131 and a second sealing member 132. Among them, the structure shown in the drawings takes the example that the first sealing member 131 fills the gap G between two adjacent batteries 120, and the second sealing member 132 has a layered structure. In some embodiments, when the sealing member includes the first sealing member 131 and the second sealing member 132, the first sealing member 131 may also adopt, for example Figure 6 in the form, and the second sealing member 132 may also adopt, for example Figure 8 in the form, and are not limited to the above embodiments.

[0064] In an embodiment of the present invention, when the first sealing member 131 is a potting glue layer and the second sealing member 132 is provided at the same time, the second sealing member 132 can further prevent the potting glue from flowing out through the first through hole 1111, ensuring the formation of the potting glue layer.

[0065] It should be understood that according to different design requirements and the structural characteristics of the battery pack, in one embodiment, regardless of the installation position and structural form of the sealing member 130, the sealing member 130 may only adopt one of the potting glue layer and the gasket, or the potting glue layer and the gasket may be used separately at different positions, and are not limited to the above embodiments.

[0066] In an embodiment of the present invention, the battery 120 may be a cylindrical battery. Among them, since the flying device requires a long endurance, the requirement for the energy density of the battery pack is relatively high. In the existing batteries 120 using a ternary system, the nickel content of the battery 120 needs to be relatively high (for example, the nickel content is greater than 60%), that is, above the 6 series, and even needs to reach the 9 series to meet the requirement of the flying device for the energy density. Of course, the increase in energy density also means an increase in the risk of thermal runaway. In this regard, the cylindrical battery has the characteristics of small volume and lower capacity of a single battery 120 compared with other types of batteries 120 (such as square shell batteries 120). Therefore, by using the cylindrical battery, the present invention can further reduce the risk of thermal runaway.

[0067] It should be noted that Figures 1 to 6In the illustrated embodiments, the battery box body 110 of the battery pack is taken as an example in which it is generally in a closed box-like structure, that is, the battery box body 110 has a top plate and a bottom plate 111, and of course, it also includes side plates 112 connected between the top plate and the bottom plate 111. At this time, the battery box body 110 is connected to the flying device via one of its top plate and bottom plate 111. In some embodiments of the present invention, different from the above structural design, the battery box body 110 of the battery pack 100 applicable to the flying device proposed by the present invention can also be in a trough-like structure. Specifically, the battery box body 110 has a bearing plate and a plurality of side plates 112. The bearing plate is the wall surface on the side of the battery box body 110 away from the flying device. One ends of the plurality of side plates 112 are respectively connected to the bearing plate, and the other ends together enclose the box opening of the battery box body 110 (that is, the trough opening of the trough-like structure). Accordingly, the battery box body 110 is connected to the top or bottom of the flying device via this box opening, and the flying device closes the box opening of the battery box body 110. In other words, when the battery pack is arranged at the bottom of the flying device, the fuselage (or vehicle body 200, etc.) of the flying device is connected to the box opening at the top of the battery box body 110 to serve as the top plate of the battery box body 110. Or, when the battery pack is arranged at the top of the flying device, the fuselage (or vehicle body 200, etc.) of the flying device is connected to the box opening at the bottom of the battery box body 110 to serve as the bottom plate 111 of the battery box body 110.

[0068] It should be noted that taking the battery box body 110 in a trough-like structure and the bottom plate 111 being provided with a first through hole 1111 as an example, at this time, the top of the battery box body 110 and the vehicle body 200 of the flying car may not have a direct connection relationship. For example, it can be connected to the bottom of the vehicle body 200 via the side wall of the battery box body 110 through other connection structures (such as a hoisting structure, etc.), and accordingly, it is ensured that the flying car closes the bottom box opening. In some embodiments, when the battery box body 110 is in a trough-like structure and the first through hole is provided in the top plate, the bottom of the battery box body 110 and the vehicle body 200 of the flying car may not have a direct connection relationship. For example, it can be connected to the top of the vehicle body 200 via the side wall of the battery box body 110 through other connection structures, and accordingly, it is ensured that the flying car closes the top box opening. In other words, in various possible embodiments that conform to the design concept of the present invention, the box opening of the battery box body 110 faces the flying device, and a first through hole is provided on the side facing away from the flying device. On this basis, the battery box body 110 is installed on the flying device, but it does not limit at which position of the battery box body 110 and through what connection structure it is installed on the flying device.

[0069] Refer to Figure 10 and Figure 11 , Figure 10 which representatively shows a three-dimensional exploded view of a part of the structure of the battery pack; Figure 11 which representatively shows Figure 4An enlarged schematic view of part D in []. In an embodiment of the present invention, the bottom wall 122 of the battery 120 has an exposed area 1221, and the exposed area 1221 is the area of the positive projection of the first through hole 1111 on the bottom wall 122. For a battery 120, the proportion of the area of the exposed area 1221 in the area of the bottom wall 122 is 10% - 85%, such as 10%, 15%, 25%, 50%, 70%, 85%, etc. Through the above structural design, the present invention can avoid the excessive area of the exposed area 1221, so as to ensure that there is enough connection space between the battery 120 and the battery box 110, ensure the fixation and sealing between the battery 120 and the battery box 110, and at the same time can avoid the too small area of the exposed area 1221, so as to ensure that enough external air can contact and exchange heat with the exposed area 1221 of the battery 120 through the first through hole 1111, and ensure a significant improvement in the heat exchange performance of the battery 120.

[0070] As Figure 11 As shown in the figure, in an embodiment of the present invention, an explosion-proof valve 123 is provided on the bottom wall 122 of the battery 120 housing, and at least part of the explosion-proof valve 123 is exposed in the first through hole 1111. Through the above structural design, when the battery 120 has a thermal runaway, the present invention can facilitate the high-temperature substances ejected by the explosion-proof valve 123 to be ejected through the first through hole 1111, reduce or avoid the blockage of the high-temperature substances, improve the spraying effect of the explosion-proof valve 123, and ensure safety.

[0071] Based on the structural design that at least part of the explosion-proof valve 123 of the battery 120 is exposed in the first through hole 1111, in an embodiment of the present invention, the explosion-proof valve 123 can be entirely within the range of the exposed area 1221. Through the above structural design, the present invention can completely avoid the shielding of the bottom plate 111 during the spraying of the explosion-proof valve 123, and further ensure the safety of the battery pack.

[0072] As Figure 10 As shown in the figure, in an embodiment of the present invention, the battery 120 can be a cylindrical battery 120, that is, the top wall and the bottom wall 122 of the battery 120 housing are respectively circular.
