At the same time, the distances between different plates and the body part are different, which is conducive to adaptively adjusting the positions of the plates according to the position of the second protrusion, reducing the redundant space in the slot, and improving the compactness of the structure.

[0038] In some embodiments, the vehicle further comprises a wire harness, the support beam is provided with a wire passing hole penetrating through the support beam, the wire passing hole is in communication with the slot, and the wire harness can pass through the wire passing hole and be arranged in the slot.

[0097] The protrusion 111 extends into the slot 410a through the open position of the slot 410a, so that the protrusion 111 can utilize the internal space of the support beam 410.

[0098] The vehicle 1000 in the embodiment of the present disclosure increases the total volume of the battery 100 under the condition that the total volume of the vehicle 1000 is constant by providing the protrusion 111 on the battery 100 and making the protrusion 111 occupy the internal space of the support beam 410, which is beneficial to improve the capacity of the battery 100, utilizes the redundant space in the support beam 410, improves the utilization rate of the space in the vehicle 1000, and is beneficial to make the structure of the vehicle 1000 more compact.

[0099] It can be understood that in some embodiments, the top cover 12 forms the first box wall 11.

[0100] It can be understood that the space inside the protrusion 111 is beneficial to improve the capacity of the battery 100.

[0102] The first component 20 refers to the sum of each component located in the accommodating cavity 10a.

[0103] It can be understood that the side of the recess 111a away from the protruding direction is open and communicates with the accommodating cavity 10a.

[0104] In this way, on the one hand, the wall thickness of each part of the first box wall 11 is the same, which facilitates the manufacture of the first box wall 11 and the protrusion 111; on the other hand, the first component 20 can utilize the space inside the protrusion 111, which is conducive to improving the capacity of the battery 100.

[0105] In some embodiments, the protruding direction of at least part of the first box wall 11 is the wall thickness direction of the first box wall 11.

[0106] The specific manner in which a part of the first box wall 11 protrudes to form the protrusion 111 is not limited, for example, a part of the first box wall 11 is punched in the wall thickness direction of the first box wall 11 by a mold to form the protrusion 111 and the recess 111a.

[0107] In some embodiments, referring to FIGS. 6 and 7, at least part of the first component 20 is located in the slot 410a, which is further conducive to improving the capacity of the battery 100.

[0108] The specific type of components included in the first component 20 is not limited.

[0109] For example, referring to FIGS. 6 and 7, the first component 20 includes a battery cell 21, so as to be conducive to directly increasing the capacity of the battery 100.

[0110] The battery cell 21 is provided with an electrode lead-out portion 211, which is used for electrical connection with the electrode lead-out portion 211 of another battery cell 21 or electrical connection with other components, so as to realize the conduction of current in the battery cell 21.

[0111] In some embodiments in which the battery cell 21 includes the electrode lead-out portion 211, the recess 111a is used for accommodating at least part of the electrode lead-out portion 211.

[0112] In this way, it is conducive to reducing the distance between the part of the surface of the battery cell 21 other than the part provided with the electrode lead-out portion 211 and the first box wall 11, so as to be conducive to improving the capacity of the battery cell 21 and making the structure of the battery 100 more compact.

[0113] In some embodiments, at least part of the electrode lead-out portion 211 is located in the slot 410a, so as to improve the utilization of the space in the slot 410a.

[0115] The first battery cell 212 refers to a specific type of battery cell 21. In embodiments where the number of battery cells 21 is more than one, all of the battery cells 21 can be the first battery cell 212, or some of the battery cells 21 can be the first battery cell 212.

[0116] In this way, the gap between the surface of the first battery cell 212 outside the electrode lead-out portion 211 and the first tank wall 11 is reduced, thereby increasing the volume of the first battery cell 212, improving the utilization of the space in the tank 10, and increasing the capacity of the battery 100.

[0117] In some embodiments, referring to the drawings, the first component 20 includes a busbar 23 connected to the battery cell 21, and the recess 111a is used to accommodate at least part of the busbar 23.

[0118] The busbar 23 is used to electrically connect different battery cells 21, so that the plurality of battery cells 21 are connected in series or parallel.

[0119] In this way, the utilization of the space in the recess 111a is improved, more space in the cavity 10a is used to arrange the battery cell 21, and the capacity of the battery 100 is improved.

[0120] In some embodiments, referring to FIG. 7, at least part of the busbar 23 is located in the slot 410a, so as to improve the utilization of the space in the slot 410a.

[0121] In some embodiments, the first component 20 includes a sampling assembly 22 connected to the battery cell 21 to obtain information of the battery cell 21, and the recess 111a is used to accommodate at least part of the sampling assembly 22.

[0122] The sampling assembly 22 is used to collect information such as temperature and voltage of the battery cell 21 by electrically connecting with the battery cell 21, and transmit the information to the battery management system (BMS) in the battery 100, so as to monitor the working state of the battery cell 21.

[0123] In this way, the utilization of the space in the recess 111a is improved, more space in the cavity 10a is used to arrange the battery cell 21, and the capacity of the battery 100 is improved.

[0124] It can be understood that the number of recesses 111a on the first tank wall 11 is one or more. The types of the first components 20 arranged in different recesses 111a can be the same or different; the type of the first component 20 arranged in the same recess 111a can be one or more.

[0125] For example, in some embodiments provided with the electrode lead-out portion 211, referring to FIG. 6, the electrode lead-out portion 211 is electrically connected with the busbar 23, and both of which are located in the same recess 111a and are electrically connected with each other, thus, it is beneficial to reduce the size of the busbar 23, so that the structure of both is more compact, and it is beneficial to make the structure of the battery 100 more compact.

[0126] For example, in some embodiments provided with the electrode lead-out portion 211, referring to FIG. 6, the electrode lead-out portion 211 is electrically connected with the busbar 23, and both of which are located in the same recess 111a and are electrically connected with each other, thus, it is beneficial to reduce the size of the busbar 23, so that the structure of both is more compact, and it is beneficial to make the structure of the battery 100 more compact.

[0127] In some embodiments provided with the busbar 23 or provided with the sampling assembly 22, referring to FIG. 6 and FIG. 7, all the battery monomers 21 are at least partially located outside the recess 111a.

[0128] All the battery monomers 21 can be only one battery monomer 21, or can be all of a plurality of battery monomers 21.

[0129] Thus, it is beneficial to reduce the gap between the surface of the battery monomer 21 outside the recess 111a and the first box wall 11, thereby increasing the volume of the battery monomer 21, improving the utilization rate of the space inside the box 10, and increasing the capacity of the battery 100.

[0130] It can be understood that the opening of the slot 410a is adapted to the arrangement position of the convex portion 111, so as to facilitate the convex portion 111 to enter the slot 410a.

[0131] For example, referring to FIG. 7, the support beam 410 is located outside the first box wall 11 along the first direction, and the opening of the slot 410a faces the first box wall 11. In the projection plane perpendicular to the first direction, the first component 20 and the slot 410a at least partially project and coincide.

[0132] Thus, it is beneficial to facilitate the convex portion 111 to directly enter the slot 410a along the first direction during the process of loading the battery 100 into the vehicle 1000, thereby simplifying the installation steps; and it is beneficial to make at least part of the first component 20 enter the space of the slot 410a, thereby facilitating to improve the capacity of the battery 100.

[0133] In some embodiments, the first direction is the height direction of the vehicle body.

[0134] The specific type of the support beam 410 and the role played in the vehicle 1000 are not limited.

[0135] For example, referring to FIG. 8, the support beams 410 include at least one of a floor cross beam 411, a seat mounting beam 412, a rocker beam 413, a center tunnel beam 414, and a floor longitudinal beam 415.

[0136] The floor cross beam 411 refers to a beam structure for placing on a floor of a passenger compartment 430, a storage compartment floor, or the like of the vehicle 1000, extending in a width direction of the vehicle 1000, and can be used to support a carpet, a cargo, or the like. The floor cross beam 411 connects other beam structures at both ends of the vehicle 1000 in the width direction of the vehicle 1000 to suppress deformation of the vehicle body.

[0137] The seat mounting beam 412 refers to a beam structure for mounting a seat, which can extend in a length direction of the vehicle 1000 or in the width direction of the vehicle 1000. The weight of the passengers of the vehicle 1000 is transmitted to the vehicle body through the seat mounting beam 412.

[0138] The rocker beam 413 refers to a beam structure extending in the length direction of the vehicle 1000 and located at one end of the vehicle 1000 in the width direction of the vehicle 1000, which is used to form a bottom structure of a door frame of the vehicle 1000. At the same time, the rocker beam 413 can also form a force transmission path to reduce damage when the vehicle 1000 is in a collision.

[0139] The center tunnel beam 414 refers to a beam structure extending in the length direction of the vehicle 1000 and located at the center of the vehicle 1000, which can form a force transmission path in the length direction of the vehicle 1000 to reduce damage when the vehicle 1000 is in a collision. The center tunnel beam 414 can be connected with at least one of the floor cross beam 411 and the seat mounting beam 412 to improve the structural strength and rigidity of the vehicle 1000.

[0140] The floor longitudinal beam 415 refers to a beam structure for placing on a floor of a passenger compartment 430, a storage compartment floor, or the like of the vehicle 1000, extending in the length direction of the vehicle 1000, which can be used to be connected with at least one of the floor cross beam 411 and the seat mounting beam 412 to further strengthen the structural strength and rigidity of the vehicle 1000. It can be used to support a carpet, a cargo, or the like.

[0141] In this way, it is beneficial to more fully utilize the internal space of various beam structures to improve the space utilization of the vehicle 1000.

[0142] In some embodiments, referring to FIG. 9, the support beam 410 is located outside the first box wall 11 along the first direction, the protrusion 111 includes a first protrusion 1114, the support beam 410 includes a first support beam 417, the first support beam 417 extends along a second direction, the first protrusion 1114 extends along a third direction, the first direction, the second direction and the third direction intersect with each other, and in a projection plane perpendicular to the first direction, a projection of the first support beam 417 intersects with a projection of the first protrusion 1114.

[0143] It can be understood that the protruding direction of the first protrusion 1114 is the third direction.

[0144] The first support beam 417 extends along the second direction, so that the first support beam 417 can inhibit the bending deformation of the vehicle 1000 caused by the load perpendicular to the second direction.

[0145] The first protrusion 1114 extends along the third direction, so that the first protrusion 1114 can inhibit the bending deformation of the vehicle 1000 caused by the load perpendicular to the third direction.

[0146] Since the extending direction of the first support beam 417 and the extending direction of the first protrusion 1114 intersect with each other, the tendency of the two to twist and deform each other can be inhibited.

[0147] In this way, through the cooperation between the first support beam 417 and the first protrusion 1114, the resistance of the vehicle 1000 to the bending deformation caused by the load in two different directions and the tendency of the mode to twist and deform are increased, the overall structural strength and rigidity of the vehicle 1000 are improved, and the safety of the vehicle 1000 is improved.

[0148] In some embodiments, the first direction, the second direction and the third direction are perpendicular to each other.

[0149] Since the extending direction of the first support beam 417 and the extending direction of the first protrusion 1114 are perpendicular to each other, the ability of the two to inhibit the tendency of twisting and deforming each other is further improved.

[0150] In some embodiments, the third direction is the length direction of the vehicle 1000, and the second direction is the width direction of the vehicle 1000.

[0151] In other embodiments, the second direction is the length direction of the vehicle 1000, and the third direction is the width direction of the vehicle 1000.

[0152] The length direction of the vehicle 1000 refers to the driving direction of the vehicle 1000. The width direction of the vehicle 1000 refers to the direction perpendicular to the driving direction of the vehicle 1000 in the horizontal plane.

[0153] In some embodiments, the first direction is a height direction of the vehicle 1000.

[0154] In some embodiments, referring to FIG. 9, the first protrusion 1114 is configured as a plurality of first protrusions 1114, each of the plurality of first protrusions 1114 extends along the third direction and is spaced apart in the second direction, and a projection of each of the plurality of first protrusions 1114 intersects with a projection of the first support beam 417 in a projection plane perpendicular to the first direction.

[0155] In this way, the plurality of first protrusions 1114 can cooperate with the first support beam 417, further improving the structural strength and rigidity of the vehicle 1000 as a whole, and improving the safety of the vehicle 1000.

[0156] It can be understood that the plurality of battery monomers 21 can be arranged in groups, and the plurality of first protrusions 1114 are beneficial to adapt to the arrangement of the battery monomers 21 of different groups in the accommodation cavity 10a respectively.

[0157] In some embodiments, referring to FIGS. 6, 9 and 10, the first protrusion 1114 includes a first protruding portion 1111 and a second protruding portion 1112, each extending along the third direction, a size of the first protruding portion 1111 along the first direction is greater than a size of the second protruding portion 1112 along the first direction, the slot 410a includes a first slot portion 410b and a second slot portion 410c, a size of the first slot portion 410b along the first direction is greater than a size of the second slot portion 410c along the first direction, the first slot portion 410b is used to accommodate the first protruding portion 1111, and the second slot portion 410c is used to accommodate the second protruding portion 1112.

[0158] The size of the first protruding portion 1111 along the first direction, referring to FIG. 6, is L1; the size of the second protruding portion 1112 along the first direction, referring to FIG. 6, is L2. L1>L2.

[0159] The size of the first slot portion 410b along the first direction is the distance between the slot bottom of the first slot portion 410b and the end surface of the first support beam 417 close to the battery 100 along the first direction, referring to FIG. 10, which is L3; the size of the second slot portion 410c along the first direction is the distance between the slot bottom of the second slot portion 410c and the end surface of the first support beam 417 close to the battery 100 along the first direction, referring to FIG. 10, which is L4. L3>L4.

[0160] In this way, the sizes of the first protruding portion 1111 and the second protruding portion 1112 are different, which facilitates the space inside the first protruding portion 1111 and the second protruding portion 1112 to adapt to different shapes and sizes of components inside the battery 100, so as to improve the compactness of the structure; the first slot portion 410b and the second slot portion 410c are adapted to the first protruding portion 1111 and the second protruding portion 1112 respectively, which is beneficial to improve the stability of the cooperation between the first protrusion 1114 and the first support beam 417.

[0161] In some embodiments, the first protruding portion 1111 has a dimension along the first direction that is greater than a dimension of the second groove portion 410c along the first direction, i.e., L1>L4, so that a direct or indirect stop cooperation between the first protruding portion 1111 and the inner wall of the first groove portion 410b along the third direction is formed, thereby further facilitating the stability of the cooperation between the first protruding portion 1114 and the first support beam 417.

[0162] In some embodiments, referring to FIGS. 6 and 10, the first protruding portion 1111 and the second protruding portion 1112 are adjacent to each other along the second direction, and the first groove portion 410b and the second groove portion 410c are in communication along the second direction.

[0163] In this way, the components arranged in the first protruding portion 1111 and the second protruding portion 1112, respectively, are arranged more concentratedly, which facilitates reducing the overall volume of the first protruding portion 1114 and the overall size of the battery 100.

[0164] In some embodiments, referring to FIGS. 9 and 10, the number of the second protruding portions 1112 is two, and each of the second protruding portions 1112 is located on the two sides of the first protruding portion 1111 along the second direction and connected to the first protruding portion 1111, and the number of the second groove portions 410c is two, and each of the second groove portions 410c is located on the two sides of the first groove portion 410b along the second direction and in communication with the first groove portion 410b. In this way, the arrangement of different components in the battery 100 is adapted.

[0165] It can be understood that, during the operation of the battery 100, the electrode lead-out portion 211 is prone to heat due to the continuous current passing through the electrode lead-out portion 211.

[0166] In some embodiments provided with the electrode lead-out portion 211 and the sampling assembly 22, the sampling assembly 22 is configured to electrically connect the electrode lead-out portion 211, the first protruding portion 1111 is configured to accommodate the electrode lead-out portion 211, and the second protruding portion 1112 is configured to accommodate the sampling assembly 22.

[0167] That is, the shape and size of the first protruding portion 1111 are adapted to the shape and size of the electrode lead-out portion 211, and the shape and size of the second protruding portion 1112 are adapted to the shape and size of the sampling assembly 22.

[0168] In this way, the overall size of the first protruding portion 1114 is reduced, and the distance between the electrode lead-out portion 211 and the sampling assembly 22 and the inner wall of the recess 111a, respectively, is reduced, thereby facilitating the compactness of the overall structure of the battery 100.

[0169] It can be understood that the number of the first support beams 417 can be one or multiple.

[0170] In some embodiments in which the number of the first support beams 417 is plural, referring to FIG. 9, the first support beams 417 all extend along the second direction and are spaced apart in the third direction, and in a projection plane perpendicular to the first direction, the projections of the first support beams 417 all intersect with the projection of the first convex portion 1114.

[0171] In this way, each first support beam 417 can be constrained with the first convex portion 1114, thereby further facilitating the stability of the cooperation between the first convex portion 1114 and the first support beam 417, and improving the overall structural strength and rigidity of the vehicle 1000.

[0172] In some embodiments in which the number of the first support beams 417 and the number of the convex portions are plural, referring to FIG. 9, in a projection plane perpendicular to the first direction, the projection of each first support beam 417 intersects with the projection of any first convex portion 1114.

[0173] In this way, each first support beam 417 can be constrained with each first convex portion 1114, thereby further facilitating the stability of the cooperation between the first convex portion 1114 and the first support beam 417, and improving the overall structural strength and rigidity of the vehicle 1000.

[0174] In some embodiments, referring to FIG. 9, in a projection plane perpendicular to the first direction, the portion of the first support beam 417 that overlaps with the projection of the first convex portion 1114 is a first beam portion 410d, and the slot 410a is located in the first beam portion 410d.

[0175] The first beam portion 410d refers to a part of the structure of the first support beam 417.

[0176] In this way, the first convex portion 1114 only occupies a part of the internal space of the first support beam 417, and the other parts of the first support beam 417 can be fixed and connected with other structures in the vehicle 1000, so as to simultaneously constrain the positions of the first support beam 417 and the battery 100.

[0177] The specific way of forming the slot 410a is not limited, for example, the first support beam 417 is formed by bending a sheet metal part, and the slot 410a is formed around the sheet metal part; or for example, a rod is processed to remove a part to form the slot 410a.

[0178] In some embodiments, referring to FIG. 10, the portion of the first support beam 417 that is misaligned with the projection of the first convex portion 1114 is a second beam portion 410e, the first beam portion 410d is bent away from the battery 100 relative to the second beam portion 410e to form the slot 410a, and the first convex portion 1114 penetrates the slot 410a along the third direction.

[0179] The slot 410a is not only open toward one side of the battery 100 in the first direction, but also open at least one end in the third direction.

[0180] In this way, on the one hand, the slot 410a is formed by bending, which is conducive to improving production efficiency and reducing production cost; on the other hand, it is conducive to adjusting the relative position of the first support beam 417 and the first protrusion 1114 in the third direction, so that the relative position of the two is arranged more flexibly.

[0181] In some embodiments, referring to FIGS. 9 and 10, the slot 410a at least partially penetrates the first beam portion 410d in the third direction, and the first protrusion 1114 is arranged in the slot 410a in the third direction. That is, the slot 410a penetrates the first beam portion 410d in the third direction.

[0182] In this way, it is more flexible to adjust the relative position of the first support beam 417 and the first protrusion 1114 in the third direction, so as to adapt to other parts in the vehicle 1000, and facilitate flexible arrangement of internal parts of the vehicle 1000.

[0183] In some embodiments provided with the first slot portion 410b and the second slot portion 410c and communicating with each other, referring to FIG. 10, at least one slot 410a is arranged at least one end of the first support beam 417 in the second direction, and the first slot portion 410b in the slot 410a is located on the side of the end surface of the second slot portion 410c close to the first support beam 417 in the second direction, and the first slot portion 410b is open away from the second slot portion 410c in the second direction.

[0184] In this way, on the one hand, the first support beam 417 is provided with the slot 410a at one end in the second direction, which is conducive to reducing the probability of deformation of the end of the first support beam 417 in the second direction during the bending process of forming the slot 410a; on the other hand, it is also convenient to adapt to the first protrusion 1114 with different sizes in the second direction.

[0185] In some embodiments, referring to FIGS. 11 and 12, the support beam 410 is located outside the first box wall 11 in the first direction, the protrusion 111 includes a second protrusion 1113, the support beam 410 includes a second support beam 416, the second support beam 416 and the second protrusion 1113 both extend in the second direction, the first direction intersects the second direction, and the second support beam 416 covers at least part of the second protrusion 1113 in the first direction.

[0186] The second support beam 416 and the second protrusion 1113 have the same extension direction, so that the second support beam 416 can cover a larger range of the second protrusion 1113.

[0187] In this way, the second protrusion 1113 can utilize more space in the slot 410a, which is conducive to increasing the volume of the battery 100 and improving the capacity of the battery 100.

[0188] It can be understood that, due to the different shapes and sizes of the components inside the battery 100, the size between the second support beam 416 and the second protrusion 1113 varies in some embodiments.

[0189] In some embodiments, referring to FIG. 12, the second protrusion 1113 includes a first portion 1113a and a second portion 1113b, and the support beam 410 includes a second support beam 416. In a projection plane perpendicular to the first direction, the projection of the second support beam 416 covers the projection of the first portion 1113a, and the projection of the second support beam 416 is completely misaligned with the second portion 1113b. The second portion 1113b is located on one side of the second support beam 416 along a third direction, and the third direction intersects with the first direction and the second direction.

[0190] In this way, in the case that the size and arrangement position between the second support beam 416 and the second protrusion 1113 vary greatly, a part of the second protrusion 1112 can be located in the slot 410a and a part of the second protrusion 1112 can be located outside the slot 410a, thereby avoiding unnecessary redundancy caused by the excessive volume of the second support beam 416, and improving the flexibility of the internal arrangement of the vehicle 1000.

[0191] In some embodiments, referring to FIGS. 13 and 14, the slot 410a has a first opening 410f facing the first tank wall 11 along the first direction, and the slot 410a further includes a second opening 410g provided on one side along the third direction. The second portion 1113b extends out of the second support beam 416 through the second opening 410g.

[0192] In this way, through the first opening 410f, the second protrusion can enter the slot 410a, and through the second opening 410g, a part of the second protrusion can be located outside the second support beam 416, so as to realize the flexible arrangement between the second protrusion and the second support beam 416.

[0193] In some embodiments, referring to FIG. 15, the first tank wall 11 includes a body portion 112 and a second protrusion 1113, and the second protrusion 1113 protrudes relative to the body portion 112.
