[0071] The battery device generally includes a battery box and a battery cell located in the battery box, and the battery box is used to withstand external impact and pressure, protect the inside from physical damage, and reduce the risk caused by collision or falling.

[0072] In order to improve the stability of the battery box and facilitate the installation of the battery device components, the related art sets a horizontal and vertical limiting beam structure on the outside of the battery box, and the support beam and the limiting beam separate the box into multiple accommodation grooves.

[0073] A protective shell for protecting the battery cell is installed in the battery box, and the protective shell needs to be directly matched with the shape of the inside of the box. For different specifications of the battery box, a new mold needs to be opened for mold production to match the shape and size of the protective shell with the battery box, and the mold cost and production cost are high.

[0074] Therefore, how to reduce the production cost of the protective shell is an important topic in the research and development of the battery device and its related components.

[0078] The following embodiments take the electric device as a vehicle for example for convenience of description.

[0079] In combination with the accompanying drawings, Figure 1 The vehicle 1000 can be a fuel automobile, a gas automobile, or a new energy automobile, and the new energy automobile can be a pure electric automobile, a hybrid electric automobile, or a range extended automobile, etc. The vehicle 1000 is internally provided with a battery device 100, which can be arranged at the bottom, the head, or the tail of the vehicle 1000. The battery device 100 can be used for power supply of the vehicle 1000, for example, the battery device 100 can be used as an operating power supply of the vehicle 1000. The vehicle 1000 can further include a controller 200 and a motor 300, and the controller 200 is used to control the battery device 100 to supply power to the motor 300, for example, to meet the working power demand of the vehicle 1000 during starting, navigation, and driving.

[0080] In some embodiments of the present application, the battery device 100 can not only be used as an operating power supply of the vehicle 1000, but also be used as a driving power supply of the vehicle 1000, to replace or partially replace fuel or natural gas to provide driving power for the vehicle 1000.

[0081] In combination with the accompanying drawings, Figures 2-4 The embodiments of the present application provide a battery device 100, which includes a battery box 10 and a battery monomer 20. The battery box 10 includes a first box 1 and a plurality of protective shells 3. The first box 1 includes a main frame 11, and the main frame 11 is provided with a plurality of mounting spaces 111. At least one protective shell 3 is arranged in each mounting space 111, and the battery monomer 20 is arranged in the protective shell 3.

[0082] The battery device 100 can be a secondary battery or a primary battery, and can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery monomer 20 and the battery device 100 can be in the shape of a cylinder, a flat body, a cuboid, or other shapes, etc.

[0083] The battery box 10 is used to provide a containing space for the battery monomer 20, and the battery box 10 can adopt various structures. In some embodiments, the battery box 10 can include a first box 1 and a second box 2, the first box 1 and the second box 2 are mutually covered, and the first box 1 and the second box 2 jointly define a containing space for containing the battery monomer 20.

[0084] Among them, the first box 1 and the second box 2 can be a hollow structure with one end open, and the second box 2 is covered on the open side of the first box 1, so that the first box 1 and the second box 2 jointly define a containing space; or the second box 2 can be a plate structure, and the first box 1 can be a hollow structure with one side open, and the open side of the second box 2 is covered on the open side of the first box 1. Of course, the battery box 10 formed by the first box 1 and the second box 2 can have various shapes, such as a cylinder, a cuboid, etc.

[0085] In some embodiments, the second box 2 can be an upper cover structure different from the structure of the first box 1, of course, the second box 2 can also be the same as the structure of the first box 1, and the embodiment is described based on the structure of the first box 1.

[0086] The first box 1 includes a main frame 11, and the main frame 11 is provided with a plurality of mounting spaces 111. For the mounting space 111 described in the embodiment, it can be understood as a slot open on one side along the third direction Z shown in the figure, or as a port structure open on both sides along the third direction Z. As long as it has a certain containing space and includes a side wall surrounding the containing space, it can be understood as the mounting space 111 in the embodiment.

[0087] Among them, the third direction Z is a direction perpendicular to the bottom wall surface, and in some embodiments, the third direction Z is perpendicular to the first direction X and the second direction Y respectively.

[0088] The protective shell 3 is used to contain the battery monomer 20 and protect the battery monomer 20. However, the protective shell 3 of the embodiment is designed as a split body from the originally integrated shell structure, the number of protective shells 3 is multiple, and the size of the protective shell 3 is made into a standard part, and the function of the originally integrated structure is realized through the combination of multiple protective shells 3.

[0089] One or more protective shells 3 can be installed in each mounting space 111. In some embodiments, the width of the protective shell 3 is greater than or equal to 300mm, for example, the width of the protective shell 3 can be 300mm-1000mm, and the length is greater than or equal to 500mm, for example, the length of the protective shell 3 can be 500mm-1000mm, and the specific size is determined according to the specification of the battery box 10.

[0090] Taking an example that one protective shell 3 is installed in each installation space 111, the plurality of protective shells 3 are matched with the plurality of installation spaces 111 one by one, and the shape and size of the protective shell 3 match the size of the installation space 111, so that the plurality of protective shells 3 can be respectively installed in the plurality of installation spaces 111.

[0091] The shape of the protective shell 3 can be a box shape with an open upper end, a tray shape, etc., and of course can also be a box shape with a cover that can be closed. Each protective shell 3 is provided with a receiving groove 31, and one or more battery monomers 20 are installed in the receiving groove 31.

[0092] As can be known from the above description, the protective shell 3 in the embodiment is different from the protective shell 3 of the related art which is directly adapted to the plurality of installation spaces 111, but the plurality of split structures of the protective shell 3 are used to match the plurality of installation spaces 111, which not only facilitates the processing of the protective shell 3 and improves the production efficiency, but also can omit the connecting part between the adjacent two protective shells 3, thereby reducing the material cost.

[0093] In combination with the accompanying Figure 6 As shown in the drawings, in some examples, the protective shell 3 includes a first bottom wall 32 and a first side wall 33 connected to the first bottom wall 32, and the first bottom wall 32 and the first side wall 33 enclose a receiving groove 31 for placing the battery monomer.

[0094] The shape of the first bottom wall 32 can be a rectangle in the drawing, or other shapes such as a circle, a triangle, etc., and the specific shape of the first bottom wall 32 is determined according to the shape of the installation space 111.

[0095] The number of the first side wall 33 can be multiple, for example, when the first bottom wall 32 is a rectangle, the number of the first side wall 33 is four. The plurality of first side walls 33 can be integrally connected or integrally formed during processing.

[0096] The material of the first bottom wall 32 and the first side wall 33 can be a material such as a polymer-based composite material, a carbon fiber composite material, a plastic and mineral composite material, etc., as long as it meets certain insulation and structural strength, and the embodiment will not be enumerated one by one.

[0097] The protective shell 3 is designed to include the first bottom wall 32 and the first side wall 33 connected to the first bottom wall 32 in the embodiment, which has a simple structure, is easy to process, and has high production efficiency.

[0098] In combination with the accompanying Figures 4-6 As shown in the drawings, in some examples, the first side wall 33 of at least one side of the protective shell 3 is provided with a frame 331 extending outwardly from the receiving groove 31, and the frame 331 is arranged on the main body frame 11.

[0099] The frame 331 can be a flange formed by outwardly turning the first side wall 33, or can be connected to the first side wall 33 by mechanical connection such as welding, bonding, riveting, etc. after the first side wall 33 is connected to the first bottom wall 32.

[0100] Taking the four first side walls 33 in the figure as an example, in some embodiments, the four first side walls 33 can each be provided with a frame 331, the length of the frame 331 can be the same as the length of the first side wall 33, and the lower surface of the frame 331 can be directly placed on the main frame 11, and in some embodiments, the frame 331 and the main frame 11 can also be connected by mechanical connection.

[0101] The protective shell 3 is designed to have a frame 331, which is placed on the main frame 11 by the frame 331, which not only facilitates the positioning and installation of the protective shell 3, but also plays a certain fixing role to a certain extent, improving the stability of the protective shell 3 installed on the main frame 11.

[0102] In some examples, optionally, at least one frame 331 of the protective shell 3 is provided with a wire harness fixing structure 332.

[0103] The reason for setting the wire harness fixing structure 332 is that the wire harness inside the battery box 10 is difficult to wire, especially under working conditions such as extrusion or impact, the high-voltage wire harness is prone to contact with the battery monomer 20, and the high-voltage wire harness refers to a voltage exceeding 60 volts (V) as high voltage, and in some embodiments, high voltage can be defined as 120V or higher.

[0104] Therefore, the present embodiment utilizes the frame 331 to form the wire harness fixing structure 332, so that the high-voltage wire harness can be placed outside the protective shell 3 body through the wire harness fixing structure 332, and the high-voltage wire harness is laid and protected through the wire harness fixing structure 332, which not only facilitates the connection and wiring of the wire harness, but also reduces the risk of contact between the wire harness and the battery monomer 20.

[0105] In some examples, optionally, the wire harness fixing structure 332 includes a wire passage 3321, and the length direction of the wire passage 3321 is arranged along the length direction of the frame 331 where the wire passage 3321 is located.

[0106] The wire harness fixing structure 332 is designed to include the wire passage 3321, which can facilitate the laying of the wire harness and can fix and protect the wire harness.

[0107] When the frame 331 has a certain thickness, the wire passage 3321 can be formed on the surface of the frame 331 by machining processes such as cutting, and when the frame 331 is a flange structure with a smaller thickness, the wire passage 3321 can be formed by flange bending.

[0108] Of course, the harness fixing structure 332 of the present embodiment is not limited to this, and can also be a hook or a hanging hole provided on the frame 331 (not shown in the drawings).

[0109] In combination with the accompanying Figure 6 and the accompanying Figure 7 As shown in the drawings, in some examples, the frame 331 includes, in order from the direction away from the accommodation groove 31, a first bent portion 3322, a second bent portion 3323, and a third bent portion 3324, which are arranged adjacent to each other at an angle, and the first bent portion 3322, the second bent portion 3323, and the third bent portion 3324 enclose the wire passing groove 3321.

[0110] In some embodiments, the frame 331 of the present embodiment is a turned-up portion bent outwardly from the side wall, and the turned-up portion is formed in the wire passing groove 3321 of the present embodiment after being bent.

[0111] The first bent portion 3322 and the second bent portion 3323 can correspond to two opposite side walls of the wire passing groove 3321, and the second bent portion 3323 can correspond to the bottom wall of the wire passing groove 3321, and the first bent portion 3322, the second bent portion 3323, and the third bent portion 3324 form a U-shaped groove structure.

[0112] When the height of the main body frame 11 is greater than the height of the first side wall 33, the first bent portion 3322 can be bent again to form a fourth bent portion 3325 close to one end of the first side wall 33, the fourth bent portion 3325 protrudes upward and forms a resulting U-shaped structure, so that the height of the first bent portion 3322 is flush with the third bent portion 3324, further reducing the risk of the harness inside the wire passing groove 3321 from being detached.

[0113] The frame 331 is designed to include the first bent portion 3322, the second bent portion 3323, and the third bent portion 3324 arranged in order and arranged at an angle, and the wire passing groove 3321 is enclosed by the bending of the three, which is simple in structure and easy to process.

[0114] In some examples, the frame 331 further includes a lapping portion 3326 located on the side of the third bent portion 3324 away from the second bent portion 3323, the lapping portion 3326 is arranged at an angle with the third bent portion 3324 and lapped on the main body frame 11.

[0115] The lapping portion 3326 can be perpendicular to the first side wall 33, and the lapping portion 3326 needs to be slightly higher than the main body frame 11 to meet the lapping on the groove wall.

[0116] The reason for configuring the lap joint 3326 is that when the first bending portion 3322, the second bending portion 3323, and the third bending portion 3324 are arranged, the frame 331 forms a U-shaped groove, and thus it is difficult to directly lay on the main body frame 11.

[0117] Therefore, the third bending portion 3324 of the embodiment is further configured with a lap joint 3326 on the side away from the second bending portion 3323. In some embodiments, the lap joint 3326 is a strip-shaped plate body, and of course the cross-sectional shape can be other shapes besides rectangular, which will not be enumerated one by one in this embodiment.

[0118] The first bending portion 3322, the second bending portion 3323, the third bending portion 3324, the fourth bending portion 3325, and the lap joint 3326 are all integral structures or integrally formed structures, and the lap joint 3326 is used to facilitate the laying of the frame 331 on the main body frame 11. The main body frame 11 includes two second side walls 112 and two limiting beams 113 arranged along the second direction Y, and at least one support beam 114.

[0119] In some examples, optionally, along the length direction of the wire slot 3321, the opposite ends of the wire slot 3321 have openings.

[0120] Taking the wire slot 3321 along the length direction in the first direction X in the figure as an example, both ends of the wire slot 3321 are open structures, especially when the wire slot 3321 is formed by edge bending, the opening can be directly formed. Of course, when the wire slot 3321 is processed in other forms (such as injection molding), the wire slot 3321 structure with open ends can also be directly formed.

[0121] The opposite ends of the wire slot 3321 have openings, which is beneficial for the introduction and exit of the wire harness, and can further facilitate the installation and fixation of the wire harness.

[0122] In some examples, optionally, along the length direction of the wire slot 3321, the wire slot 3321 is connected to the wire slot 3321 of another protective shell 3 adjacent to itself.

[0123] Taking the wire slot 3321 along the length direction in the first direction X in the figure as an example, one of the wire slots 3321 is adjacent to another wire slot 3321 along the first direction X, and the two wire slots 3321 are connected to each other through the respective openings.

[0124] Taking the wire slots 3321 adjacent along the second direction Y in the figure as an example, the length directions of the two wire slots 3321 are also along the second direction Y (not shown in the figure), and then the two wire slots 3321 are connected to each other through the respective openings.

[0125] The two wire-through grooves 3321 of the two protective shells 3 are connected in length direction, so that the wire harness can be introduced or led out from one wire-through groove 3321 to the other wire-through groove 3321, and the layout of the wire harness is further facilitated.

[0126] If the two wire-through grooves 3321 are adjacent in length direction but arranged in a direction perpendicular to the respective length directions, the two wire-through grooves 3321 can be disconnected (not shown in the figure), for example, the tray adjacent in the second direction Y has two adjacent wire-through grooves 3321, and the length directions of the wire-through grooves 3321 are arranged in the first direction X, so that the two wire-through grooves 3321 adjacent in the second direction Y are disconnected.

[0127] In combination with the figures shown in Figure 3 , the figures shown in Figure 4 , and the figures shown in Figure 5 , in some examples, the main body frame 11 includes a second side wall 112, a limiting beam 113, and a support beam 114, two limiting beams 113 are arranged in the main body frame 11 in a spaced manner, and divide the internal space of the main body frame 11 into a first part 115, a second part 116, and a third part 117 arranged in sequence in the first direction X, the first direction X being the arrangement direction of the two limiting beams 113, and at least one support beam 114 is located in the second part 116 and divides the second part 116 into a plurality of mounting spaces 111.

[0128] The two limiting beams 113 are respectively located at the two ends of the main body frame 11 in the first direction X, and have a spacing with the second side wall 112 adjacent in the first direction X, and the spacing forms the first part 115 and the third part 117 described above, for mounting electric control devices such as a battery management system (BMS).

[0129] The limiting beam 113 can limit the battery monomer 20 in the mounting space 111, and reduce the possibility of stress invading the first part 115 and the third part 117.

[0130] The second part 116 is used for mounting the support beam 114, and the number of the support beam 114 can be one or more, for example, the two intersecting limiting beams 113 in the figure, one of which is arranged in the first direction X, and the other is arranged in the second direction Y, in some embodiments, the first direction X and the second direction Y are perpendicular, and the first direction X can be the length direction of the box, and the second direction Y is the width direction of the box.

[0131] At this time, the second part 116 is divided into four mounting spaces 111 by the two support beams 114, and the four protective frames are respectively mounted in the four mounting spaces 111.

[0132] The support beam 114 not only divides the internal space of the battery box 10 into zones, but also supports and fixes the second side walls 112 around the perimeter, thereby improving the overall structural strength and stability of the battery box 10.

[0133] Since wiring harnesses (such as high-voltage wiring harnesses) are usually connected to the electrical control devices of the first part 115 and the second part 116, the wiring trough 3321 needs to be designed with this characteristic in mind.

[0134] Therefore, combined with the appendix Figure 3 and 4 As shown, in some examples, optionally, the frame 331 adjacent to the second sidewall 112 is provided with a wire groove 3321, the length direction of which is set along the first direction X.

[0135] Because of the presence of the limiting beam 113, the groove walls on both sides of the third part 117 along the first direction X are the limiting beam 113 and not the second side wall 112. Only the outer frame 331 along the second direction Y of the protective shell 3 can be adjacent to the second side wall 112. The wire groove 3321 can be directly set here, and the other frame 331 does not need to be set with the wire groove 3321.

[0136] When routing wire harnesses, wire harnesses connected to electrical components in the first part 115 or the second part 116 can be directly laid in the wire passage 3321 along the first direction X, which makes it more convenient to route wires through the wire passage 3321.

[0137] Combined again with the appendix Figures 3-5 As shown, in some examples, optionally, the limiting beam 113 is provided with a notch 1131 adjacent to the wire passage groove, and one end of the wire passage groove 3321 adjacent to the notch 1131 is placed in the notch 1131.

[0138] The notch 1131 can be provided at opposite ends of the limiting beam 113 along the second direction Y, and located on the upper side of the limiting beam 113. Of course, the notch 1131 can also be provided at other positions of the limiting beam 113, such as the lower side of the end, or adjacent to the end, as long as it can satisfy the requirement that one end of the wire groove 3321 can be inserted.

[0139] When laying the wire harness, the notch 1131 allows the wire harness to pass through the limiting beam 113, and makes it easier for the electrical components in the first part 115 or the third part 117 to pass through the limiting beam 113 and enter the wire channel 3321, making it easier for the wire harness to run between the first part 115 and the second part 116.

[0140] In some examples, the first housing 1 may optionally include a bottom wall connected to the main frame 11 and forming an installation groove with the installation space 111, with the protective shell 3 located within the installation groove.

[0141] The first box body 1 is designed to further include a bottom wall, the bottom wall and the mounting space 111 enclose a mounting groove, and the protective shell 3 is located in the mounting groove, which can further improve the mounting stability and better protect the bottom of the battery monomer 20 through the bottom wall.

[0142] The second bottom wall 12 can include a bottom guard plate, which can be rectangular in shape or other shapes. The second bottom wall 12 can enclose a groove structure with the first part 115, the second part 116 and the third part 117 described above, and cooperate with the support beam 114 and the limiting beam 113 to form a mounting groove structure.

[0143] In some examples, the first box body 1 further includes a buffer 13, which is located in the mounting space 111, and the protective shell 3 is installed on the buffer 13.

[0144] The buffer 13 can be a plate-shaped piece, or a block, a column, etc., which will not be listed one by one in this embodiment. The buffer 13 can be made of rubber, foam, plastic and other deformable materials, mainly for shock absorption.

[0145] The number of buffers 13 can match the number of protective shells 3, and the bottom of each protective shell 3 is located on a buffer 13. The size of the buffer 13 can be equal to, less than or greater than the size of the first bottom wall 32.

[0146] The buffer 13 is installed in the mounting space 111, which can reduce the impact of external impact or collision on the protective shell 3 and the internal battery monomer 20, and can reduce the possibility of damage to the structure of the battery monomer 20 under impact or collision.
