[0027] In some embodiments, the battery device further comprises an elastic buffer provided between the bracket and the frame.

[0028] In this way, the elastic buffer and the bracket can jointly absorb impact energy when the battery device is subjected to extrusion or collision impact, reducing the risk of damage to the box body and the battery cells therein.

[0049] In addition, if there are these terms "first", "second", these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0050] In this application, unless otherwise explicitly specified and limited, if there are terms such as "mounting", "connecting", "connecting", "fixing" and the like, these terms should be broadly understood. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0052] It is to be noted that when an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar expressions used herein are used for illustrative purposes only and are not intended to be limiting.

[0053] At present, from the development of market situation, the application of battery is more and more widely. The battery is not only applied to the energy storage power system of water power, fire power, wind power and solar power station, but also widely applied to the electric bicycle, electric motorcycle, electric vehicle and other electric vehicles, military equipment, aerospace and other fields. With the continuous expansion of the application field of battery, the demand of its market is also increasing.

[0054] The battery is composed of one or more battery monomers. For each battery, the plurality of battery monomers constituting it can be connected in series or in parallel or in mixed connection. Among them, mixed connection means that there are series connection and parallel connection in the plurality of battery monomers.

[0055] The battery monomer is the smallest unit of the battery, and in the structure of the battery monomer, it includes the shell, the electrolyte and the electrode assembly. The electrode assembly is the component where the electrochemical reaction occurs in the battery monomer, and the electrode assembly includes the positive plate, the negative plate and the diaphragm. The shell can include one or more electrode assemblies. The electrode assembly is mainly formed by winding or stacking the positive plate and the negative plate, and the diaphragm is usually arranged between the positive plate and the negative plate.

[0056] The shell is a structure with one end opening and hollow inside. The electrode assembly is arranged inside the shell, and the end cover is arranged at the opening of the shell. The end cover is closed to form the internal environment of the battery monomer at the opening. Of course, the end cover and the shell can be integrated. Specifically, the end cover and the shell can form a common connecting surface before other components enter the shell. When it is necessary to encapsulate the inside of the shell, the end cover is closed to the shell. The shell can be of various shapes and sizes, such as rectangular parallelepiped, cylindrical, hexagonal prism, etc. Specifically, the shape of the shell can be determined according to the specific shape and size of the electrode assembly. The material of the shell can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc. The embodiments of the present application do not make special limitation.

[0057] In the related art, the fixing structure such as the bottom guard plate fixing frame and the wire harness fixing frame is connected with the corresponding counterpart fitting on the electrical equipment. The electrical equipment is a vehicle, an electric toy, a mobile phone, etc. The counterpart fitting on the electrical equipment is a vehicle bottom guard plate, a wire harness, etc. The cooperation mode of the above fixing structure and the box body of the battery device mainly has two kinds: the first kind is that a plurality of adapter supports are welded on the box body frame of the battery device, and the fixing structure is correspondingly fixed on the adapter supports; the second kind is that the fixing structure is integrally extruded with the box body frame.

[0058] In the former, because there are many types of fixing structures, a plurality of adapter supports need to be welded, and the adjacent adapter supports have spacing and spatial position degree requirements. An auxiliary positioning tool needs to be additionally configured to improve the welding accuracy of the adapter supports. The process is complicated and the welding quality requirement is high. In the latter, because the fixing structure is integrally extruded with the box body frame, when a certain fixing structure is damaged, the entire box body needs to be scrapped, the maintenance cost is too high, and multiple fixing structures are difficult to be fixed at different positions, and the space utilization rate is low.

[0059] In summary, the cooperation mode of the fixing structure and the box body of the battery device in the related art has great limitations, and it is difficult to meet the combined requirements of high integration and economy of the battery device.

[0060] Based on the above situation, in view of the problem that the cooperation mode of the fixing structure and the box body of the battery device in the related art has great limitations, and it is difficult to meet the combined requirements of high integration and economy of the battery device, one or more embodiments of the present application provide a battery device. By setting the support on the side of the frame away from the accommodation space, and spacing at least two fixing seats in the support along the intersecting first direction and second direction, the support is distributed with multiple fixing seats in multiple directions in space, multiple fixing seats distributed in different directions in space are integrated, the counterpart fitting on the electrical equipment of different specifications can be adaptively selected to select the fixing seat of the corresponding direction and position on the support for positioning connection, so that the fixing point of the fixing seat on the battery device has higher adaptability and consistency, and the functional structure integration of the battery device is improved. At the same time, by detachably setting the support on the frame, the disassembly efficiency of the support is improved, the adaptively matched support can be conveniently replaced according to the corresponding specification of the electrical equipment, the maintenance difficulty of the support is reduced, and the structure property of the support integrated with multiple fixing seats distributed in different directions in space is matched, which effectively meets the combined requirements of high integration and economy of the battery device.

[0061] In the embodiments of the present application, the battery device can be used in various energy storage systems using the battery device as an energy storage element, or used in a power consumption device using the battery device as a power supply. The power consumption device can be, but is not limited to, a mobile phone, a tablet, a notebook computer, an electric toy, an electric tool, an electric vehicle, an electric car, a ship, a spacecraft, etc. The electric toy can include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, an electric plane toy, etc. The spacecraft can include an airplane, a rocket, a space shuttle, a spacecraft, etc.

[0062] Referring to Figure 1 and Figure 2 , Figure 1 is a structural schematic view of a vehicle of an embodiment of the present application, Figure 2 is another structural schematic view of a vehicle of an embodiment of the present application. The vehicle 20 can be a fuel car, a gas car, or a new energy car. The new energy car can be a pure electric car, a hybrid car, or an extended-range car, etc. The vehicle 20 is internally provided with a battery device 10, which can be arranged at the bottom, the head, or the tail of the vehicle 20. The battery device 10 can be used for power supply of the vehicle 20, for example, the battery device 10 can be used as an operating power supply of the vehicle 20. The vehicle 20 can further include a controller 30 and a motor 40. The controller 30 is used to control the battery device 10 to supply power to the motor 40, for example, to meet the power demand of the vehicle 20 during starting, navigation, and driving.

[0063] Of course, in other embodiments, the battery device 10 can not only be used as an operating power supply of the vehicle 20, but also be used as a driving power supply of the vehicle 20, instead of or partially instead of fuel or natural gas to provide driving power for the vehicle 20.

[0064] Referring to Figure 3 The battery device 10 mentioned in the present application can include a battery module or a battery pack, etc. The battery cell 200 can constitute the smallest unit of the battery device 10.

[0065] Referring to Figure 4 , Figure 5 and Figure 6 The embodiments of the present application provide a battery device 10, which includes a box body 100 and a support 300.

[0066] The box body 100 includes a frame 110, which encloses a containing space 111 for containing the battery cell 200.

[0067] The bracket 300 is detachably disposed on a side of the frame 110 away from the accommodating space 111. The bracket 300 is provided with a plurality of fixing seats 310, at least two fixing seats 310 are spaced apart along a first direction X, and at least two fixing seats 310 are spaced apart along a second direction Y, and the first direction X and the second direction Y intersect.

[0068] It should be noted that, in this application, the housing 100 refers to a structure that houses and mechanically supports multiple battery cells 200. The housing 100 of the battery device 10 may also integrate a BMS (Battery Management System), a thermal management system, etc. All battery cells 200 are arranged in a predetermined orientation within the housing 100, such as in an array or in a single row or column.

[0069] In some embodiments, see Figure 3 The housing 100 may further include a first housing portion 101 and a second housing portion 102, wherein the first housing portion 101 and the second housing portion 102 cover each other. The first housing portion 101 may be a hollow structure with one end open, and the second housing portion 102 may be a plate-shaped structure, with the second housing portion 102 covering the open side of the first housing portion 101. The first housing portion 101 and the second housing portion 102 may also both be hollow structures with one end open, with the open side of the first housing portion 101 covering the open side of the second housing portion 102. The first housing portion 101 and the second housing portion 102 may have various shapes, such as a cylinder, a rectangular parallelepiped, etc.

[0070] When the first box body 101 covers the top of the second box body 102, the first box body 101 is also called an upper box cover, and the second box body 102 is also called a lower box.

[0071] In this application, the frame 110 may be the first box body 101 or the entire structure of the first box body 101. The frame 110 may be made of a metal material with a certain strength, such as steel, alloy material, etc., so that the box body 100 as a whole has good structural stability.

[0072] In this application, see Figure 4 、 Figure 5 and Figure 6 The side of the frame 110 facing away from the receiving space 111 refers to the side facing away from the receiving space 111 along the thickness direction of the frame 110, that is, the outer side of the frame 110. Correspondingly, the inner side of the frame 110 is the side close to the receiving space 111 along the thickness direction of the frame 110.

[0073] The support 300 can be detachably connected to the side of the frame 110 away from the accommodation space 111 through structural members such as bolt connections, buckle connections, etc., so as to facilitate the disassembly and replacement of the support 300. The support 300 can be made of L-shaped angle steel, I-shaped steel, or Z-shaped steel, so that the support 300 has good structural strength. Similarly, the fixing seat 310 on the support 300 can also be made of L-shaped angle steel, I-shaped steel, or Z-shaped steel.

[0074] The number of supports 300 can be multiple, such as Figure 5 , the frame 110 is a rectangular body, and the support 300 has two, which are respectively detachably arranged on the two opposite outer sides of the frame 110; or, for example, the frame 110 is a rectangular body, and the number of supports 300 is four, which are respectively detachably arranged on the four outer sides of the frame 110.

[0075] The fixing seat 310 arranged on the support 300 refers to a fixing structure for connecting with the mating part of the electrical equipment. The mating part of the electrical equipment can be, but is not limited to, the bottom guard plate of the automobile, the wire harness of the automobile, the ground wire of the automobile, etc. At this time, the fixing seat 310 corresponds to the bottom guard plate fixing seat, the wire harness fixing seat, the ground wire fixing seat, etc.

[0076] The fixing seat 310 can be arranged on the support 300 through adhesion, welding, or bolt connections. For example, all the fixing seats 310 are integrally stamped and formed with the support 300, so as to improve the positional stability of the fixing seat 310 on the support 300. The fixing seat 310 can be, but is not limited to, a square body support, a cylindrical support, etc. The fixing seat 310 is provided with a through threaded hole. The mating part of the electrical equipment is provided with a threaded alignment hole. After the fixing seat 310 and the mating part of the electrical equipment are stacked, the mating part of the electrical equipment is fixed to the fixing seat 310 by screwing the threaded hole on the fixing seat 310 and the threaded alignment hole on the mating part.

[0077] In the present application, referring to Figure 4 , Figure 5 and Figure 6 , the first direction X and the second direction Y can be arranged vertically in space, such as two mutually perpendicular planes, or can be arranged to intersect but not perpendicular in space, such as two planes intersecting at a certain angle. When the first direction X and the second direction Y are perpendicular to each other in space, the first direction X and the second direction Y can be any two of the length direction, the height direction, and the width direction of the support 300. Of course, the first direction X and the second direction Y can be two arc surface or arc line directions intersecting each other.

[0078] For example, in one embodiment, referring to 4, the first direction X is the length direction of the support 300, the second direction Y is the height direction of the support 300, and the third direction Z is the width direction of the support 300. Alternatively, in another embodiment, referring toFigure 5 The first direction X is a length direction of the support 300, the second direction Y is a width direction of the support 300, and the third direction Z is a height direction of the support 300.

[0079] Correspondingly, the interval distribution of the at least two fixing seats 310 along the first direction X can be understood as that the at least two fixing seats 310 are interval distributed along the same plane in space, and in the same plane, all the fixing seats 310 are in the same straight line, and all the fixing seats 310 have no height difference, or all the fixing seats 310 are not in the same straight line, and at least two fixing seats 310 have height difference in the plane.

[0080] The interval distribution of the at least two fixing seats 310 along the second direction Y is the same, and will not be repeated here.

[0081] The battery device 10 of the present application, by arranging the support 300 on the side of the frame 110 away from the accommodation space 111, and interval arranging at least two fixing seats 310 along the intersecting first direction X and second direction Y, makes the support 300 have multiple fixing seats 310 distributed in multiple directions in space, integrates multiple fixing seats 310 distributed in different directions in space, and the corresponding direction and position of the fixing seat 310 on the support 300 can be adaptively selected to be connected by the mating parts on the electrical equipment of different specifications, so that the fixing point of the fixing seat 310 on the battery device 10 has higher adaptability and consistency, and the functional structure integration of the battery device 10 is improved; at the same time, by detachably arranging the support 300 on the frame 110, the disassembly efficiency of the support 300 is improved, the support 300 of the corresponding specification can be conveniently replaced, the maintenance difficulty of the support 300 is reduced, and the structure property of the support 300 integrating multiple fixing seats 310 distributed in different directions in space is matched, so that the high integration and economic composite requirements of the battery device 10 are effectively met.

[0082] In addition, it should be further pointed out that the support 300 arranged on the frame 110 of the box body 100 of the battery device 10 can absorb part of the energy when the battery device 10 is subjected to extrusion, collision impact, reduce the impact force directly transmitted to the battery monomer 200 inside the box body 100, protect the box body 100 and the battery monomer 200 inside, and reduce the risk of damage to the box body 100 and the battery monomer 200 inside.

[0083] In some embodiments of the present application, referring to Figure 5 、 Figure 6 、 Figure 7 and Figure 8 , the at least two fixing seats 310 are interval distributed along the third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0084] Specifically, the bracket 300 can be, but is not limited to, a U-shaped, Z-shaped, T-shaped, L-shaped or the like structure, and the first direction X, the second direction Y and the third direction Z correspond to the length direction, the width direction and the height direction of the bracket 300 respectively.

[0085] Exemplarily, the first direction X, the second direction Y and the third direction Z correspond to three mutually perpendicular spatial planes on the bracket 300 respectively, along the first direction X, the bracket 300 is provided with eight fixing seats 310, and among the eight fixing seats 310, at least three fixing seats 310 are not on the same straight line, that is, at least two fixing seats 310 are distributed in staggered positions along the first direction X. Similarly, along the second direction Y, the bracket 300 is provided with three fixing seats 310, and among the three fixing seats 310, the three fixing seats 310 are not on the same straight line, that is, at least two fixing seats 310 are distributed in staggered positions along the second direction Y. Similarly, along the third direction Z, the bracket 300 is provided with two fixing seats 310, and the perpendicular projections of the two fixing seats 310 along the third direction Z do not coincide.

[0086] In this way, the fixing seats 310 are distributed at each position in space on the bracket 300, which can adapt to connect the mating fittings on the power equipment of various specifications.

[0092] Further, referring to Figure 6 and Figure 9 , the plurality of fixing seats 310 are arranged non-equidistantly along the first direction X on the first side plate 301; and / or the plurality of fixing seats 310 are arranged non-equidistantly along the second direction Y on the first side plate 301.

[0093] Specifically, along the first direction X on the first side plate 301, the plurality of fixing seats 310 can include wire harness fixing seats, bottom guard plate fixing seats, ground wire fixing seats, etc., the shapes of the respective fixing seats 310 are different, matching the corresponding types of fittings, at the same time, the geometric centers of the plurality of fixing seats 310 are connected on the same straight line, and the geometric centers of any two adjacent fixing seats 310 are not connected on the same straight line, so that the plurality of fixing seats 310 on the first side plate 301 are arranged non-equidistantly along the first direction X.

[0094] Similarly, along the second direction Y on the first side plate 301, the plurality of fixing seats 310 can include wire harness fixing seats, bottom guard plate fixing seats, ground wire fixing seats, etc., the shapes of the plurality of fixing seats 310 are different, matching the corresponding types of fittings, at the same time, the geometric centers of the plurality of fixing seats 310 are connected on the same straight line, and the geometric centers of any two adjacent fixing seats 310 are not connected on the same straight line, so that the plurality of fixing seats 310 on the first side plate 301 are arranged non-equidistantly along the second direction Y.

[0095] In the above structure, by providing a plurality of fixing seats 310 arranged non-equidistantly along the first direction X and / or a plurality of fixing seats 310 arranged non-equidistantly along the second direction Y on the first side plate 301 of the bracket 300, it is possible to meet the requirements of corresponding connection with the non-spacing distribution of accessories on the electrical equipment and adapt to the connection adaptability with electrical equipment of various specifications.

[0096] Further, see Figure 7 and Figure 9 , the vertical distances between the at least two fixing seats 310 of the first side panel 301 and the second side panel 302 are not equal; and / or, the vertical projections of the at least two fixing seats 310 of the first side panel 301 relative to the second side panel 302 do not overlap.

[0097] It should be noted that the vertical distance between the fixing base 310 and the second side plate 302 refers to the vertical distance between the top end of the fixing base 310 and the second side plate 302 .

[0098] Specifically, see Figure 8 and Figure 9 The first side panel 301 has two mounting bases, designated as mounting base No. 1 311 and mounting base No. 2 312. Mounting base No. 1 311 and mounting base No. 2 312 are spaced apart along a first direction X or a third direction Z. The first direction X and the third direction Z can be understood as two planes perpendicular to each other in space. The vertical distance D1 between mounting base No. 1 311 and the second side panel 302 is the same as the vertical distance D2 between mounting base No. 2 312 and the second side panel 302. D1 is greater than D2, indicating a height difference between the two mounting bases on the bracket 300. This allows for adaption to components at different heights on the electrical equipment.

[0100] In the above structure, by setting the vertical distances between at least two fixing seats 310 of the first side panel 301 and the second side panel 302 to be unequal, there is a height difference between at least two fixing seats 310 on the first side panel 301, so as to adapt to matching accessories at different heights on the electrical equipment.

[0101] The at least two fixing seats 310 on the first side plate 301 are staggered in space, and the probability of mutual interference of different fixing seats 311 when connected to the corresponding mating fittings on the electrical equipment is reduced.

[0102] In some embodiments of the present application, referring to Figure 6 、 Figure 7 、 Figure 8 and Figure 10 , the second side plate 302 on the bracket 300 is provided with a plurality of fixing seats 310.

[0103] Specifically, on the second side plate 302, the at least two fixing seats 310 are spaced apart along the first direction X, and / or the at least two fixing seats 310 are spaced apart along the second direction Y, and / or the at least two fixing seats 310 are spaced apart along the third direction Y, the first direction X, the second direction Y and the third direction Y are three mutually perpendicular planes in space.

[0104] In the above structure, the plurality of fixing seats 310 are integrated on the second side plate 302 to form a plurality of fixing points for mating connection with the mating fittings on the electrical equipment, and the first side plate 301 also has a plurality of fixing points integrated thereon, so that the fixing seats 310 at the corresponding positions on the first side plate 301 or the second side plate 302 can be selected for mating connection according to the distribution position of the mating fittings on the electrical equipment, thereby improving the installation adaptability of the battery device 10 to electrical equipment of various specifications, and further improving the structural integration and use economy of the battery device 10.

[0105] Further, referring to Figure 6 and Figure 10 , the plurality of fixing seats 310 are non-equidistantly arranged along the first direction X on the second side plate 302; and / or the plurality of fixing seats 310 are non-equidistantly arranged along the second direction Y on the second side plate 302.

[0106] Specifically, on the second side plate 302, along the first direction X, the plurality of fixing seats 310 can include wire harness fixing seats, bottom guard plate fixing seats, ground wire fixing seats, etc., the shapes of the respective fixing seats 310 are different, matched with the corresponding types of mating fittings, at the same time, the geometric centers of the plurality of fixing seats 310 are connected on the same straight line, and the geometric centers of any two adjacent fixing seats 310 are not connected on the same straight line, so that the plurality of fixing seats 310 on the second side plate 302 are non-equidistantly arranged along the first direction X.

[0107] Similarly, on the second side plate 302, along the second direction Y, the plurality of fixing seats 310 can include a wire harness fixing seat, a bottom guard plate fixing seat, a ground wire fixing seat, etc., the shapes of the plurality of fixing seats 310 are different, matched with the corresponding type of counterfitting, at the same time, the geometric centers of the plurality of fixing seats 310 are connected on the same straight line, and the geometric centers of any two adjacent fixing seats 310 are not connected on the same straight line, so that the plurality of fixing seats 310 on the second side plate 302 are arranged in a non-equidistant manner along the second direction Y.

[0108] In the above structure, by arranging a plurality of fixing seats 310 arranged in a non-equidistant manner along the first direction X and / or a plurality of fixing seats 310 arranged in a non-equidistant manner along the second direction Y on the second side plate 302 of the bracket 300, and cooperating with the plurality of fixing seats 310 on the first side plate 301, the demand for corresponding and positioning connection with the counterfitting distributed in a non-interval manner on the electrical equipment can be further met, and the connection adaptability with electrical equipment of various specifications can be adapted.

[0109] Further, referring to Figure 6 and Figure 10 , the perpendicular distances between the at least two fixing seats 310 on the second side plate 302 and the first side plate 301 are not equal; and / or, the perpendicular projections of the at least two fixing seats 310 on the second side plate 302 on the second side plate 302 do not coincide.

[0110] It should be noted that the perpendicular distance between the fixing seat 310 and the first side plate 301 refers to the perpendicular distance between the geometric center of the fixing seat 310 and the first side plate 301.

[0111] Specifically, referring to Figure 10 , the second side plate 302 has two fixing seats, which are defined as No. 3 fixing seat 313 and No. 4 fixing seat 314, respectively, the No. 3 fixing seat 313 and the No. 4 fixing seat 314 are distributed in an interval along the first direction X, and the first direction X can be understood as a plane in space. The perpendicular distance between the No. 3 fixing seat 313 and the first side plate 301 is D3, the perpendicular distance between the No. 4 fixing seat 314 and the first side plate 301 is D4, and D3 is greater than D4, that is, the two have a height difference in the bracket 300, so as to adapt to the counterfitting on the electrical equipment at different positions.

[0112] In addition, in the above embodiment, the perpendicular projection of the No. 3 fixing seat 313 on the first side plate 301 and the perpendicular projection of the No. 4 fixing seat 314 on the first side plate 301 do not coincide, and the two are staggered in space, reducing the probability of mutual interference of the No. 3 fixing seat 313 and the No. 4 fixing seat 314 when connected with the corresponding counterfitting on the electrical equipment.

[0113] In the above structure, by setting the vertical distance between the at least two fixing seats 310 of the second side plate 302 and the first side plate 301 to be unequal, the at least two fixing seats 310 on the second side plate 302 have a height difference, so as to adapt to the mating fittings at different positions on the electrical equipment.

[0114] By setting the vertical projection of the at least two fixing seats 310 of the second side plate 302 on the first side plate 301 to be non-coincident, the at least two fixing seats 310 on the second side plate 302 are staggered in space, reducing the probability of mutual interference of different fixing seats 311 when connected to the corresponding mating fittings on the electrical equipment.

[0115] Further, referring to Figure 6 、 Figure 7 and Figure 8 , the bracket 300 and the fixing seat 310 are configured as an integral molding structure.

[0116] Specifically, the bracket 300 and the fixing seat 310 are integrally stamped and formed.

[0117] Compared with the molding method of separately forming the fixing seat 310 and then welding it on the bracket 300, by configuring the steel bracket 300 and the fixing seat 310 as an integral molding structure, the manufacturing process and processing error of the bracket 300 and the fixing seat 310 can be simplified, the bracket 300 and the fixing seat 310 have higher structural strength, and the positional stability of the fixing seat 310 on the bracket 300 can also be improved.

[0118] In some embodiments of the present application, referring to Figure 6 、 Figure 7 and Figure 8 , the bracket 300 is further provided with a plurality of mounting seats 320 and a plurality of fasteners 330, and the mounting seat 320 is detachably connected to the frame 110 through the corresponding fastener 330.

Correspondingly, the frame 110 is provided with a plurality of connecting seats (not shown in the figure), which can be threaded seats or threaded holes, and the fastener 330 is a fastening bolt. The fastener 330 passes through the mounting seat 320 and is threadedly connected with the connecting seat on the frame 110, so as to detachably fix the bracket 300 on the frame 110.

[0120] Compared with directly welding the support 300 on the frame 110, the support 300 is locked and fixed on the frame 110 through the cooperation structure of the fastener 330 and the mounting seat 320, facilitating the disassembly, maintenance and replacement of the support 300.

[0123] In the above structure, the elastic buffer cooperates with the support 300 to absorb impact energy when the battery device 10 is subjected to extrusion and collision impact, reducing the risk of damage to the box body 100 and the battery monomer 200 inside. The elastic buffer cooperates with the support 300 to play a double buffering protection role, improving the impact resistance of the box body 100.

[0124] Of course, in some embodiments of the present application, the box body 100 further comprises a bottom guard plate (not shown in the figure), which is provided at the bottom of the frame 110, and the support 300 is detachably provided on the frame 110.

[0125] Specifically, the bottom guard plate is integrally stamped and formed with the frame 110, reducing the assembly complexity of the box body 100. Alternatively, the bottom guard plate is detachably provided at the bottom of the frame 110 by adhesion, clamping or bolt connection, facilitating the maintenance, disassembly and replacement of the bottom guard plate. The bottom guard plate can be understood as an outer bottom plate of the box body 100, which can be used for assembly connection with the vehicle chassis.

[0126] The support 300 is detachably provided on the frame 110 by adhesion, clamping or bolt connection, also facilitating the overall maintenance, disassembly and replacement of the support 300. The support 300 protrudes from the peripheral wall of the frame 110, facilitating the alignment and connection of the fixing seat 310 thereon with the corresponding counterpart on the electric equipment.

[0127] The bottom guard plate of the box body 100 can serve as the mounting, positioning and supporting structure of the support 300. At the same time, the bottom guard plate can pre-absorb part of the impact energy when the bottom of the battery device 10 is subjected to extrusion and collision impact, reducing the risk of damage to the support 300, the box body 100 and the battery monomer 200 inside the box body 100.
