[0023] In a projection plane perpendicular to the first direction, the projection of the first support beam intersects with the projection of the first convex portion. In this way, through the cooperation between the first support beam and the first convex portion, the resistance of the vehicle to the bending deformation generated by loads in two different directions and the tendency to resist torsional deformation are increased, the overall structural strength and stiffness of the vehicle are improved, and the safety of the vehicle is improved.
[0024] In some embodiments, the first convex portion is configured as a plurality of, the plurality of first convex portions all extend along the third direction and are spaced apart in the second direction, and in a projection plane perpendicular to the first direction, the projections of the plurality of first convex portions all intersect with the projection of the first support beam.

[0026] In some embodiments, the first raised portion and the second raised portion are adjacent to each other in the second direction, and the first slot portion and the second slot portion are connected to each other along the second direction. In this way, it is beneficial for the components arranged in the first raised portion and the second raised portion to be arranged more concentratedly, which is beneficial to reducing the overall volume of the first convex portion and reducing the outer contour size of the battery.
[0027] In some embodiments, the battery further includes a sampling component. The battery cell includes an electrode lead-out portion. The sampling component is used for electrically connecting to the electrode lead-out portion. The first convex portion is used for accommodating the electrode lead-out portion, and the second convex portion is used for accommodating the sampling component. In this way, it is beneficial to reduce the overall size of the first convex portion, and at the same time, it is beneficial to reduce the distances between the electrode lead-out portion and the sampling component respectively and the inner wall of the concave portion, which is beneficial to making the overall structure of the battery more compact.
[0028] In some embodiments, a plurality of first support beams are configured. The plurality of first support beams all extend along the second direction and are spaced in the third direction. And, in the projection plane perpendicular to the first direction, the projections of the plurality of first support beams all intersect with the projection of the first convex portion. In this way, each first support beam can achieve mutual restraint with the first convex portion, which is further beneficial to improving the cooperation stability between the first convex portion and the first support beam, and improving the overall structural strength and stiffness of the vehicle.
[0029] In some embodiments, in the projection plane perpendicular to the first direction, the part where the first support beam coincides with the projection of the first convex portion is the first beam portion, and the slot is located in the first beam portion. In this way, the first convex portion only occupies a part of the internal space of the first support beam, which is convenient for fixing and connecting other parts of the first support beam to other structures in the vehicle, so as to synchronously constrain the positions of the first support beam and the battery.
[0030] In some embodiments, the part where the first support beam is misaligned with the projection of the first convex portion is the second beam portion. The first beam portion is bent away from the battery relative to the second beam portion to form a slot, and the first convex portion penetrates through the slot along the third direction. On the one hand, forming the slot by means of bending processing is beneficial to improving production efficiency and reducing production costs; on the other hand, it is beneficial to adjust the relative position between the first support beam and the first convex portion in the third direction, so that the relative position arrangement of the two is more flexible.
[0031] In some embodiments, the slot at least partially penetrates at least part of the first beam portion along the third direction, and the first convex portion penetrates through the slot along the third direction. In this way, it is beneficial to more flexibly adjust the relative position between the first support beam and the first convex portion in the third direction, so as to adapt to other components in the vehicle, which is beneficial to the flexibility of the layout of the internal components of the vehicle.
[0032] In some embodiments, the support beam is located outside the first box wall along the first direction.

[0034] In some embodiments, the second convex portion includes a first part and a second part. In a projection plane perpendicular to the first direction, the projection of the second support beam covers the projection of the first part, and the projection of the second support beam is completely misaligned with the second part. The second part is located on one side of the second support beam along the third direction, and the third direction intersects with the first direction and the second direction pairwise. In this way, when the dimensions and layout positions between the second support beam and the second convex portion are quite different, it is beneficial to make a part of the second convex portion located in the slot and a part located outside the slot, so as to avoid unnecessary redundancy caused by the excessive volume of the second support beam and improve the flexibility of the vehicle interior layout.
[0035] In some embodiments, the slot has a first opening. The first opening faces the first box wall along the first direction. The slot further includes a second opening provided on one side along the third direction. The second part extends out of the second support beam through the second opening. In this way, through the first opening, it is beneficial to enable the second convex portion to enter the slot, and through the second opening, a part of the second convex portion can be located outside the second support beam, so as to achieve flexible configuration between the second convex portion and the second support beam.
[0036] In some embodiments, the first box wall further includes a body portion. The second convex portion protrudes relative to the body portion. The second support beam includes a plurality of plate bodies bent and connected along the third direction. In a projection plane perpendicular to the first direction, the maximum distance between the plate body that coincides with the projection of the second convex portion and the body portion is greater than the maximum distance between the plate body that is misaligned with the projection of the second convex portion and the body portion. In this way, forming the second support beam by bending a plurality of plate bodies through a bending process is beneficial to simplify the production process, reduce the production cost, and improve the production efficiency; at the same time, the distances between different plate bodies and the body portion are different, which is beneficial to adaptively adjust the positions of the plate bodies according to the position of the second convex portion, beneficial to reducing the redundant space in the slot, and improving the compactness of the structure.
[0037] In some embodiments, the vehicle further includes a wiring harness. The support beam is provided with a through wire hole, and the wire hole communicates with the slot. The wiring harness can pass through the wire hole and be disposed in the slot. In this way, the support beam can play a certain protective role for the wiring harness, and at the same time, it is beneficial to make more full use of the internal space of the slot and improve the space utilization rate.
[0038] In some embodiments, the vehicle further includes a mounting plate. The support beam is located on one side of the battery along the first direction. The mounting plate is disposed between the battery and the support beam. The part of the mounting plate opposite to the convex portion along the first direction protrudes towards the support beam along the first direction and is recessed along the first direction on the other side facing the first box wall. In this way, the mounting plate can play an isolation and protection role between the battery and the vehicle frame, which is beneficial to reducing the damage to other components in the vehicle caused by the failure of the battery.
[0039] In some embodiments, the vehicle frame and the battery jointly enclose to form the passenger compartment of the vehicle, and the box wall forms the passenger compartment floor of the passenger compartment. In this way, it is beneficial to reduce the number of components in the vehicle and improve the compactness of the vehicle structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0090] The battery 100 is used as the power source of the vehicle 1000 to provide electrical energy for other electrical devices in the vehicle 1000, such as motors, screens, stereos, refrigerators, etc.
[0091] The box body 10 is used to provide a layout position and a protection function for the components installed in the receiving cavity 10a, such as the battery cells 21.
[0092] The box wall refers to the structure that forms the outer surface of the box body 10 and encloses to form the receiving cavity 10a. It can be understood that the aforementioned top cover 12 and bottom cover 13 each form one or more box walls respectively.
[0093] The first box wall 11 refers to the box wall among the respective box walls that is used to enclose the receiving cavity 10a and forms the convex portion 111. It can be that all the box walls are the first box wall 11, or part of the box walls are the first box wall 11.
[0094] The battery cell 21 is the smallest divided component in the battery 100 that can realize the charging and discharging functions through electrochemical reactions.
[0095] The support beam 410 is the beam structure that forms the vehicle frame 400. The support beam 410 can be used to install and fix other components in the vehicle 1000, such as the battery 100, etc.; it can also be used to support other components in the vehicle 1000, such as seats, etc.
[0096] The support beam 410 is provided with a groove 410a, that is, the surface portion of the support beam 410 is recessed to form a groove, so that the weight of the support beam 410 is reduced while the stiffness, strength, bending resistance and torsional resistance of the support beam 410 meet the design requirements, thereby playing a lightweight role.
[0097] It can be understood that at least one side of the slot 410a is open.
[0098] The protrusion 111 extends into the slot 410 a through the open position of the slot 410 a , so that the protrusion 111 can utilize the inner space of the support beam 410 .
[0099] The vehicle 1000 in the embodiment of the utility model increases the total volume of the battery 100 by providing a protrusion 111 on the battery 100 and making the protrusion 111 occupy the internal space of the support beam 410, so that when the total volume of the vehicle 1000 is constant, the capacity of the battery 100 is increased, the redundant space in the support beam 410 is utilized, the utilization rate of the space in the vehicle 1000 is improved, and the structure of the vehicle 1000 is made more compact.
[0100] It can be understood that, in some embodiments, the top cover 12 forms the first box wall 11 .
[0101] It is understandable that utilizing the space inside the protrusion 111 is beneficial to increasing the capacity of the battery 100 .
[0102] Specifically, see Figure 6 The battery 100 includes a first component 20, which is located in the accommodating cavity 10a. At least a portion of the inner surface of the first box wall 11 protrudes toward the outer surface to form a convex portion 111 on the outer surface, and a concave portion 111a is formed at a position on the inner surface corresponding to the convex portion 111, and the concave portion 111a is used to accommodate at least a portion of the first component 20.
[0103] The first component 20 refers to the sum of all components located in the accommodating cavity 10a.
[0104] It can be understood that the side of the recess 111 a away from the protruding direction is open and communicated with the accommodating cavity 10 a.
[0105] In this way, on the one hand, it is beneficial to make the wall thickness of each part of the first box wall 11 the same, which is convenient for manufacturing 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 beneficial to increase the capacity of the battery 100.
[0106] In some embodiments, at least a portion of the first box wall 11 protrudes in a direction that is the thickness direction of the first box wall 11 .
[0107] The specific manner in which a part of the first box wall 11 protrudes to form the convex part 111 is not limited. For example, a part of the first box wall 11 is stamped along the wall thickness direction of the first box wall 11 by a mold to form the convex part 111 and the concave part 111a.
[0108] In some embodiments, referring to Figure 6 and Figure 7 , at least a part of the first component 20 is located in the slot 410a to further facilitate increasing the capacity of the battery 100.
[0109] The specific types of components included in the first component 20 are not limited.
[0110] Exemplarily, referring to Figure 6 and Figure 7 , the first component 20 includes a battery cell 21. In this way, it is beneficial to directly increase the capacity of the battery 100.
[0111] The battery cell 21 is provided with an electrode lead-out part 211. The electrode lead-out part 211 is used for electrically connecting with the electrode lead-out parts 211 of other battery cells 21 or with other components to achieve the conduction of current in the battery cell 21.
[0112] In some embodiments where the battery cell 21 includes the electrode lead-out part 211, the concave part 111a is used to accommodate at least a part of the electrode lead-out part 211.
[0113] In this way, it is beneficial to reduce the distance between the part of the battery cell 21 other than the part where the electrode lead-out part 211 is provided on the surface and the first box wall 11, thereby being beneficial to increasing the capacity of the battery cell 21 and making the structure of the battery 100 more compact.
[0114] In some embodiments, at least a part of the electrode lead-out part 211 is located in the slot 410a to improve the utilization rate of the space in the slot 410a.
[0115] In some embodiments, referring to 6, the battery cell 21 includes a first battery cell 212. The electrode lead-out part 211 of the first battery cell 212 is located in the concave part 111a and at least a part other than the electrode lead-out part 211 is located outside the concave part 111a.
[0116] The first battery cell 212 refers to a specific type of battery cell 21. In embodiments where the number of battery cells 21 is multiple, all the battery cells 21 may be first battery cells 212, or some of the battery cells 21 may be first battery cells 212.
[0117] Thus, it is beneficial to reduce the gap between the surface of the first battery cell 212 outside the electrode lead-out portion 211 and the first box wall 11, thereby increasing the volume of the first battery cell 212, improving the utilization rate of the space inside the box body 10, and increasing the capacity of the battery 100.
[0118] In some embodiments, referring to the figure, the first component 20 includes a bus bar 23 connected to the battery cell 21, and the recess 111a is used to accommodate at least a part of the bus bar 23.
[0119] The bus bar 23 is used to electrically connect different battery cells 21 so as to realize series and parallel electrical connections among multiple battery cells 21.
[0120] Thus, it is beneficial to improve the utilization rate of the space inside the recess 111a, beneficial to have more space in the accommodation cavity 10a for arranging the battery cells 21, and beneficial to increase the capacity of the battery 100.
[0121] In some embodiments, referring to Figure 7 , at least a part of the bus bar 23 is located in the slot 410a to improve the utilization rate of the space inside the slot 410a.
[0122] In some embodiments, the first component 20 includes a sampling component 22. The sampling component 22 is used to connect to the battery cell 21 to obtain information of the battery cell 21, and the recess 111a is used to accommodate at least a part of the sampling component 22.
[0123] The sampling component 22 is used to electrically connect to the battery cell 21 to collect information such as the temperature and voltage of the battery cell 21 and transfer this information to the Battery Management System (BMS) in the battery 100 so as to monitor the working state of the battery cell 21.
[0124] Thus, it is beneficial to improve the utilization rate of the space inside the recess 111a, beneficial to have more space in the accommodation cavity 10a for arranging the battery cells 21, and beneficial to increase the capacity of the battery 100.
[0125] It can be understood that the number of the recesses 111a on the first box 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 types of the first components 20 arranged in the same recess 111a can be one or more.
[0126] For example, in some embodiments provided with the electrode lead-out portion 211, referring to Figure 6, the electrode lead-out part 211 is electrically connected to the bus bar 23, and the two electrically connected to each other are located in the same concave part 111a. In this way, it is beneficial to reduce the size of the bus bar 23, make the structures of the two more compact, and make the structure of the battery 100 more compact.
[0127] For another example, in some embodiments provided with the electrode lead-out part 211, the bus bar 23 and the sampling component 22, refer to Figure 6 , at least part of the electrode lead-out part 211, the bus bar 23 and the sampling component 22 are located in the same concave part 111a. In this way, it is beneficial to reduce the sizes of the bus bar 23 and the sampling component 22, facilitate the sampling component 22 to collect information of the bus bar 23 and the sampling component 22, and make the structure of the battery 100 more compact.
[0128] In some embodiments provided with the bus bar 23 or the sampling component 22, refer to Figure 6 and Figure 7 , at least part of all the battery cells 21 are located outside the concave part 111a.
[0129] All the battery cells 21 can be only one battery cell 21 or all of multiple battery cells 21.
[0130] In this way, it is beneficial to reduce the gap between the surface of the part of the battery cell 21 outside the concave part 111a and the first box wall 11, thereby increasing the volume of the battery cell 21, improving the utilization rate of the space inside the box 10, and increasing the capacity of the battery 100.
[0131] It can be understood that the opening of the slot 410a is adapted to the arrangement position of the convex part 111 so as to facilitate the convex part 111 to enter the slot 410a.
[0132] Exemplarily, refer to Figure 7 , the support beam 410 is located outside the first box wall 11 along the first direction, the opening of the slot 410a faces the first box wall 11, and in the projection plane perpendicular to the first direction, the first component 20 and the slot 410a at least partially overlap in projection.
[0133] In this way, during the process of loading the battery 100 into the vehicle 1000, along the first direction, the convex part 111 can directly enter the slot 410a, which is beneficial to simplifying the installation steps; it is beneficial to make at least part of the first component 20 enter the space of the slot 410a so as to be beneficial to increasing the capacity of the battery 100.
[0134] In some embodiments, the first direction is the height direction of the vehicle body.
[0135] The specific type of the support beam 410 and the role it plays in the vehicle 1000 are not limited.
[0136] Exemplarily, refer to Figure 8 , the support beam 410 includes at least one of a floor cross beam 411, a seat mounting beam 412, a sill beam 413, a center tunnel beam 414, and a floor longitudinal beam 415.
[0137] The floor cross beam 411 refers to a beam structure that is placed on the floor of the passenger compartment floor 430, storage compartment floor, etc. of the vehicle 1000 and extends along the width direction of the vehicle 1000. It can be used to carry carpets, vehicle-borne goods, etc. The floor cross beam 411 connects other beam structures at both ends of the vehicle 1000 along the width direction of the vehicle 1000 to suppress the deformation of the vehicle body.
[0138] The seat mounting beam 412 refers to a beam structure used for mounting seats. It can extend along the length direction of the vehicle 1000 or along the width direction of the vehicle 1000. Through the seat mounting beam 412, the weight of the vehicle 1000 occupants is transmitted to the vehicle body.
[0139] The sill beam 413 refers to a beam structure that extends along the length direction of the vehicle 1000 and is located at one end of the vehicle frame 400 along the width direction of the vehicle 1000. It is used to form the bottom structure of the car door frame. At the same time, the sill beam 413 can also form a force transmission path to reduce damage when the vehicle 1000 collides.
[0140] The center tunnel beam 414 refers to a beam structure that extends along the length direction of the vehicle 1000 and is located in the center of the vehicle 1000. When the vehicle 1000 collides, it can form a force transmission path along the length direction of the vehicle 1000 to reduce damage. The center tunnel beam 414 can be connected to at least one of the floor cross beam 411 and the seat mounting beam 412 to improve the structural strength and stiffness of the vehicle 1000.
[0141] The floor longitudinal beam 415 refers to a beam structure that is placed on the floor of the passenger compartment floor 430, storage compartment floor, etc. of the vehicle 1000 and extends along the length direction of the vehicle 1000. It can be used to connect to at least one of the floor cross beam 411 and the seat mounting beam 412 to further enhance the structural strength and stiffness of the vehicle 1000. It can be used to carry carpets, vehicle-borne goods, etc.
[0142] In this way, it is beneficial to make more full use of the internal space of various beam structures and improve the space utilization rate of the vehicle 1000.
[0143] In some embodiments, refer to Figure 9, the support beam 410 is located outside the first box wall 11 along the first direction. The convex portion 111 includes a first convex portion 1114, the support beam 410 includes a first support beam 417, the first support beam 417 extends along the second direction, the first convex portion 1114 extends along the third direction, the first direction, the second direction and the third direction intersect with each other, and in the projection plane perpendicular to the first direction, the projection of the first support beam 417 intersects with the projection of the first convex portion 1114.
[0144] It can be understood that the protruding direction of the first convex portion 1114 is the third direction.
[0145] 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.
[0146] The first convex portion 1114 extends along the third direction, so that the first convex portion 1114 can inhibit the bending deformation of the vehicle 1000 caused by the load perpendicular to the third direction.
[0147] Since the extending directions of the first support beam 417 and the first convex portion 1114 intersect with each other, the two can mutually inhibit the tendency of each other to twist and deform.
[0148] In this way, through the cooperation between the first support beam 417 and the first convex portion 1114, the resistance of the vehicle 1000 to the bending deformation caused by loads in two different directions and the tendency to twist and deform are increased, the overall structural strength and stiffness of the vehicle 1000 are improved, and the safety of the vehicle 1000 is improved.
[0149] In some embodiments, the first direction, the second direction and the third direction are perpendicular to each other.
[0150] Since the extending directions of the first support beam 417 and the first convex portion 1114 are perpendicular to each other, the ability of the two to mutually inhibit the occurrence of torsional deformation is further improved.
[0151] 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.
[0152] 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.
[0153] 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.
[0154] In some embodiments, the first direction is the height direction of the vehicle 1000.
[0155] In some embodiments, referring to Figure 9 , a plurality of first convex portions 1114 are arranged, and the plurality of first convex portions 1114 all extend along a third direction and are spaced apart in a second direction. Moreover, in a projection plane perpendicular to the first direction, the projections of the plurality of first convex portions 1114 all intersect with the projection of the first support beam 417.
[0156] In this way, the plurality of first convex portions 1114 can cooperate with the first support beam 417, further improving the overall structural strength and stiffness of the vehicle 1000 and enhancing the safety of the vehicle 1000.
[0157] It can be understood that the plurality of battery cells 21 can be arranged in groups, and the plurality of first convex portions 1114 are conducive to respectively adapting to the arrangement of different groups of battery cells 21 in the accommodation cavity 10a.
[0158] In some embodiments, referring to Figure 6 , Figure 9 and Figure 10 , the first convex portion 1114 includes a first convex part 1111 and a second convex part 1112 that both extend along the third direction. The dimension of the first convex part 1111 along the first direction is greater than the dimension of the second convex part 1112 along the first direction. The slotted groove 410a includes a first groove part 410b and a second groove part 410c. The dimension of the first groove part 410b along the first direction is greater than the dimension of the second groove part 410c along the first direction. The first groove part 410b is used to accommodate the first convex part 1111, and the second groove part 410c is used to accommodate the second convex part 1112.
[0159] The dimension of the first convex part 1111 along the first direction, referring to Figure 6 , is L1; the dimension of the second convex part 1112 along the first direction, referring to Figure 6 , is L2. L1 > L2.
[0160] The dimension of the first groove part 410b along the first direction is the distance between the bottom of the first groove part 410b and the end face of the first support beam 417 close to one end of the battery 100 along the first direction. Referring to Figure 10 , it is L3; the dimension of the second groove part 410c along the first direction is the distance between the bottom of the second groove part 410c and the end face of the first support beam 417 close to one end of the battery 100 along the first direction. Referring to Figure 10 , it is L4. L3 > L4.
[0161] Thus, the first protrusion 1111 and the second protrusion 1112 have different sizes, facilitating the spaces inside them to respectively adapt to different-shaped and -sized components inside the battery 100, so as to improve the structural compactness; the first groove portion 410b and the second groove portion 410c respectively adapt to the first protrusion 1111 and the second protrusion 1112, which is conducive to improving the cooperation stability between the first convex portion 1114 and the first support beam 417.
[0162] In some embodiments, the size of the first protrusion 1111 in the first direction is greater than the size of the second groove portion 410c in the first direction, that is, L1 > L4, so that a stop fit can be directly or indirectly formed between the first protrusion 1111 and the inner wall of the first groove portion 410b in the third direction, thereby further facilitating the improvement of the cooperation stability between the first convex portion 1114 and the first support beam 417.
[0163] In some embodiments, referring to Figure 6 and Figure 10 , the first protrusion 1111 and the second protrusion 1112 are adjacent in the second direction, and the first groove portion 410b and the second groove portion 410c are connected in the second direction.
[0164] Thus, it is beneficial for the components arranged in the first protrusion 1111 and the second protrusion 1112 to be arranged more concentratedly, which is conducive to reducing the overall volume of the first convex portion 1114 and reducing the outer contour size of the battery 100.
[0165] In some embodiments, referring to Figure 9 and Figure 10 , the number of the second protrusions 1112 is two, and they are respectively located on both sides of the first protrusion 1111 in the second direction and connected to the first protrusion 1111. The number of the second groove portions 410c is two, and they are respectively located on both sides of the first groove portion 410b in the second direction and connected to the first groove portion 410b. Thus, it is to adapt to the arrangement modes of different components inside the battery 100.
[0166] It can be understood that during the operation of the battery 100, since the electrode lead-out portion 211 continuously passes current, it is prone to heat generation.
[0167] In some embodiments provided with the electrode lead-out portion 211 and the sampling assembly 22, the sampling assembly 22 is used for electrically connecting the electrode lead-out portion 211, the first protrusion 1111 is used for accommodating the electrode lead-out portion 211, and the second protrusion 1112 is used for accommodating the sampling assembly 22.
[0168] That is to say, the shape and size of the first protrusion 1111 are convenient for adapting to the shape and size of the electrode lead-out portion 211, and the shape and size of the second protrusion 1112 are convenient for adapting to the shape and size of the sampling assembly 22.
[0169] In this way, it is beneficial to reduce the overall size of the first convex portion 1114, and at the same time, it is beneficial to reduce the distances between the electrode lead-out portion 211 and the sampling component 22 and the inner wall of the concave portion 111a respectively, which is beneficial to making the overall structure of the battery 100 more compact.
[0170] It can be understood that the number of the first support beams 417 can be one or more.
[0171] In some embodiments where the number of the first support beams 417 is more than one, refer to Figure 9 , the multiple first support beams 417 all extend along the second direction and are spaced apart in the third direction, and in the projection plane perpendicular to the first direction, the projections of the multiple first support beams 417 all intersect with the projection of the first convex portion 1114.
[0172] In this way, each of the first support beams 417 can be mutually constrained with the first convex portion 1114, which is further beneficial to improving the cooperation stability between the first convex portion 1114 and the first support beam 417, and improving the overall structural strength and stiffness of the vehicle 1000.
[0173] In embodiments where the number of the first support beams 417 and the number of the protrusions are both more than one, refer to Figure 9 , in the projection plane perpendicular to the first direction, the projection of each first support beam 417 intersects with the projection of any one of the first convex portions 1114.
[0174] In this way, each of the first support beams 417 can be mutually constrained with each of the first convex portions 1114, which is further beneficial to improving the cooperation stability between the first convex portion 1114 and the first support beam 417, and improving the overall structural strength and stiffness of the vehicle 1000.
[0175] In some embodiments, refer to Figure 9 , in the projection plane perpendicular to the first direction, the part where the first support beam 417 coincides with the projection of the first convex portion 1114 is the first beam portion 410d, and the slot 410a is located in the first beam portion 410d.
[0176] The first beam portion 410d refers to a part of the structure of the first support beam 417.
[0177] In this way, the first convex portion 1114 only occupies a part of the internal space of the first support beam 417, which is convenient for fixing and connecting other parts of the first support beam 417 to other structures in the vehicle 1000, so as to synchronously constrain the positions of the first support beam 417 and the battery 100.
[0178] The specific method 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 by surrounding it. In another example, a portion of a bar is removed by processing to form the slot 410a.
[0179] In some embodiments, see Figure 10 The portion where the first support beam 417 and the first protrusion 1114 are projected and misaligned is the second beam 410e. The first beam 410d is bent relative to the second beam 410e in a direction away from the battery 100 to form a groove 410a. The first protrusion 1114 is arranged in the third direction through the groove 410a.
[0180] The groove 410 a is not only open toward one side of the battery 100 along the first direction, but also at least one end of the groove 410 a along the third direction is open.
[0181] In this way, on the one hand, forming the groove 410a by bending processing is beneficial to improving production efficiency and reducing production costs; on the other hand, it is beneficial to adjust 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 can be arranged more flexibly.
[0182] In some embodiments, see Figure 9 and Figure 10 The slot 410a at least partially penetrates at least a portion of the first beam portion 410d along the third direction, and the first protrusion 1114 is disposed in the slot 410a along the third direction. In other words, the slot 410a penetrates the first beam portion 410d along the third direction.
[0183] In this way, it is beneficial to more flexibly adjust the relative positions of the first support beam 417 and the first protrusion 1114 in the third direction so as to adapt to other components in the vehicle 1000, which is beneficial to the flexibility of the arrangement of the internal components of the vehicle 1000.
[0184] In some embodiments, the first groove portion 410b and the second groove portion 410c are provided and the two groove portions 410c are connected to each other. Figure 10 At least one slot 410a is provided at at least one end of the first support beam 417 along the second direction, and the first slot portion 410b in the slot 410a is located on the side of the second slot portion 410c close to the end surface of the first support beam 417 along the second direction, and the first slot portion 410b is open on the side away from the second slot portion 410c along the second direction.
[0185] In this way, on the one hand, the first support beam 417 is provided with a groove 410a at one end along the second direction, which is beneficial to reducing the probability of deformation of the end of the first support beam 417 along the second direction during the bending process to form the groove 410a; on the other hand, it is also convenient to adapt to the first protrusion 1114 with different sizes along the second direction.
[0186] In some embodiments, referring to Figure 11 and Figure 12 , the support beam 410 is located outside the first box wall 11 along the first direction. The convex portion 111 includes a second convex portion 1113. The support beam 410 includes a second support beam 416. Both the second support beam 416 and the second convex portion 1113 extend along the second direction. The first direction intersects the second direction. The second support beam 416 covers at least a part of the second convex portion 1113 along the first direction.
[0187] The second support beam 416 has the same extending direction as the second convex portion 1113, so that the second support beam 416 can cover a larger area of the second convex portion 1113.
[0188] In this way, it is beneficial for the second convex portion 1113 to utilize more space in the slot 410a, which is beneficial to increasing the volume of the battery 100 and improving the capacity of the battery 100.
[0189] It can be understood that due to the different shapes and sizes of the components inside the battery 100, there are differences in the positions and sizes of the dimensions between the second support beam 416 and the second convex portion 1113 in some embodiments.
[0190] In some embodiments, referring to Figure 12 , the second convex portion 1113 includes a first part 1113a and a second part 1113b. The support beam 410 includes a second support beam 416. In the projection plane perpendicular to the first direction, the projection of the second support beam 416 covers the projection of the first part 1113a, and the projection of the second support beam 416 is completely misaligned with the second part 1113b. The second part 1113b is located on one side of the second support beam 416 along the third direction. The third direction intersects the first direction and the second direction pairwise.
[0191] In this way, when the dimensions and arrangement positions between the second support beam 416 and the second convex portion 1113 are quite different, it is beneficial for a part of the second convex portion 1112 to be located inside the slot 410a and a part to be located outside the slot 410a, so as to prevent the volume of the second support beam 416 from being too large and causing unnecessary redundancy, and improving the flexibility of the internal layout of the vehicle 1000.
[0192] In some embodiments, referring to Figure 13 and Figure 14 , the slot 410a has a first opening 410f. The first opening 410f faces the first box wall 11 along the first direction. The slot 410a further includes a second opening 410g provided on one side along the third direction. The second part 1113b extends out of the second support beam 416 through the second opening 410g.
[0193] Thus, through the first opening 410f, it is beneficial to enable the second protrusion to 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 achieve a flexible configuration between the second protrusion and the second support beam 416.
[0194] In some embodiments, referring to Figure 15 , the first box wall 11 includes a main body portion 112 and a second convex portion 1113. The second convex portion 1113 protrudes relative to the main body portion 112. The second support beam 416 includes a plurality of plate bodies 4161 bent and connected along the third direction. In a projection plane perpendicular to the first direction, the maximum distance between the plate body 4161 that coincides with the projection of the second convex portion 1113 and the main body portion 112 is greater than the maximum distance between the plate body 4161 that is misaligned with the projection of the second convex portion 1113 and the main body portion 112.
[0195] The main body portion 112 refers to the region of the first box wall 11 that is flat relative to the convex portion 111.
[0196] The maximum distance between the plate body 4161 that coincides with the projection of the second convex portion 1113 and the main body portion 112 refers to the dimension of L5 in the figure; the maximum distance between the plate body 4161 that is misaligned with the projection of the second convex portion 1113 and the main body portion 112 refers to the dimension of L6 in the figure.
[0197] Thus, forming the second support beam 416 by forming a plurality of plate bodies 4161 through a bending process is beneficial to simplifying the production process, reducing the production cost, and improving the production efficiency; at the same time, the distances between different plate bodies 4161 and the main body portion 112 are different, which is beneficial to adaptively adjusting the positions of the plate bodies 4161 according to the position of the second convex portion 1113, reducing the redundant space in the slot 410a, and improving the compactness of the structure.
[0198] In some embodiments, referring to Figure 12 , the vehicle 1000 further includes a wire harness 500. The support beam 410 is provided with a through wire hole 410h, and the wire hole 410h communicates with the slot 410a. The wire harness 500 can pass through the wire hole 410h and be disposed in the slot 410a.
[0199] The wire harness 500 refers to various flexible cables, wires, signal wires, etc. in the vehicle 1000 for transmitting force and information.
[0200] Thus, the support beam 410 can play a certain protective role for the wire harness 500, and at the same time, it is beneficial to make more full use of the internal space of the slot 410a and improve the space utilization rate.
[0201] In some embodiments, referring to Figure 16 and 17, the vehicle 1000 further includes a mounting plate 420. The support beam 410 is located on one side of the battery 100 along the first direction. The mounting plate 420 is disposed between the battery 100 and the support beam 410. The portion of the mounting plate 420 opposite to the convex portion 111 along the first direction protrudes towards the support beam 410 along the first direction and is recessed along the first direction on the other side facing the first box wall 11.
[0202] That is to say, the mounting plate 420 separates the support beam 410 from the battery 100. By generating protrusions and depressions in a partial area of the mounting plate 420, the convex portion 111 and a part of the mounting plate 420 can jointly enter the slot 410a.
[0203] In this way, the mounting plate 420 can play an isolation and protection role between the battery 100 and the vehicle frame 400, which is beneficial to reducing the damage to other components in the vehicle 1000 caused by a failure of the battery 100.
[0204] In some embodiments, the mounting plate 420 and the workshop enclose to form a passenger compartment 1000a. That is to say, the first box wall 11 does not directly form the passenger compartment 1000a.
[0205] In some embodiments, refer to Figure 18 , the vehicle frame 400 and the battery 100 jointly enclose to form the passenger compartment 1000a of the vehicle 1000, and the first box wall 11 forms the passenger compartment floor 430 of the passenger compartment 1000a.
[0206] That is to say, the first box wall 11 and the passenger compartment floor 430 are the same component and can be used to directly place components such as seats and carpets in the vehicle 1000.
[0207] In this way, it is beneficial to reduce the number of components in the vehicle 1000 and improve the structural compactness of the vehicle 1000.
