[0041] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] In the description of the embodiments of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the embodiments of the present invention.

[0043] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention.

[0044] In the embodiments of the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," or "above" a second feature may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," or "below" a second feature may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is lower in level than the second feature.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0046] like Figure 1 and Figure 2 As shown, a specific embodiment of the first aspect of the present invention provides a frame body 100. The frame body 100 includes a plurality of assembly units 110; the plurality of assembly units 110 are stacked in sequence; adjacent assembly units 110 are detachably connected to form a first storage space for storing a battery pack.

[0047] In this embodiment, by stacking multiple assembly units 110 in sequence, and by allowing adjacent assembly units 110 to be detachably connected to form a first storage space, not only can the use of welding to produce the frame body 100 be avoided, eliminating the welding and polishing process, thereby improving the production efficiency of the frame body 100 and reducing production costs; but also, when storing the frame body 100, the multiple assembly units 110 can be disassembled, which can reduce storage space pressure, thereby reducing inventory pressure and transportation pressure. When adjacent assembly units 110 are connected together to form the first storage space, the battery pack can be hoisted when it is assembled in the first storage space, which can reduce the difficulty of battery assembly and improve the convenience of battery assembly.

[0048] It should be noted that the term "a plurality" refers to at least two. In other words, the frame body 100 of this embodiment includes at least two assembly units 110. Preferably, the plurality of assembly units 110 are stacked in sequence along the vertical direction.

[0049] Exemplarily, the process of hoisting a battery pack may include:

[0050] First, the battery pack is hoisted onto the first assembly unit 110; then the second assembly unit 110 is hoisted onto the first assembly unit 110. At this time, a first storage space is formed between the two assembly units 110, and the battery pack is located in the first storage space; finally, the third assembly unit 110 and the second battery pack are hoisted in sequence, and the cycle is repeated until the battery pack is hoisted.

[0051] It can be understood that when hoisting the battery pack, the battery pack is placed from top to bottom on the corresponding assembly unit 110. When hoisting the assembly unit 110, the upper assembly unit 110 is placed from top to bottom on the adjacent assembly unit 110 on the lower layer, so that a first storage space is formed between the upper and lower adjacent assembly units 110.

[0052] In some embodiments, the assembly unit 110 includes a frame assembly 101 and a support and connection assembly 102. The support and connection assembly 102 is disposed on the frame assembly 101. The frame assemblies 101 of two adjacent assembly units 110 are detachably connected via the support and connection assembly 102, thereby forming a first storage space between the two adjacent frame assemblies 101. Specifically, one end of the support and connection assembly 102 of a given assembly unit 110 is fixedly or detachably connected to the frame assembly 101 of that assembly unit 110, and the other end of the support and connection assembly 102 is detachably connected to the frame assembly 101 of an adjacent assembly unit 110.

[0053] In this embodiment, the frame assembly 101 is provided to provide a mounting base for the battery pack, ensuring the stability of the battery pack installation. The support connection assembly 102 is provided to enable the frame assemblies 101 of two adjacent assembly units 110 to be detachably connected, ensuring the detachability of the two adjacent assembly units 110.

[0054] For example, one end of the support and connection assembly 102 of the same assembly unit 110 is welded to the frame assembly 101 of the same assembly unit 110, and the other end of the support and connection assembly 102 is detachably connected to the frame assembly 101 of the adjacent assembly unit 110. Welding the support and connection assembly 102 to the frame assembly 101 of the same assembly unit 110 can improve the assembly efficiency of the frame body 100 and enhance the smoothness of the assembly line operation.

[0055] For example, one end of the support and connection assembly 102 of the same assembly unit 110 is detachably connected to the frame assembly 101 of the same assembly unit 110, and the other end of the support and connection assembly 102 is detachably connected to the frame assembly 101 of the adjacent assembly unit 110. Detachably connecting one end of the support and connection assembly 102 of the same assembly unit 110 to the frame assembly 101 of the same assembly unit 110 eliminates the welding and polishing process, reduces the manufacturing hours of the frame body 100, improves the manufacturing efficiency of the frame body 100, and further reduces inventory and transportation pressures.

[0056] It is understood that the detachable connection method includes but is not limited to a screw fastening connection. Specifically, mounting holes are opened on the two workpieces that need to be detachably connected, screws are installed in the mounting holes, and are fixed with nuts.

[0057] like Figure 2 As shown, in some embodiments, the frame assembly 101 includes multiple crossbeams 111 and multiple longitudinal beams 112. The crossbeams 111 extend along the length of the frame body 100; the crossbeams 111 are spaced apart along the width of the frame body 100; the longitudinal beams 112 are located between two crossbeams 111 and spaced apart along the length of the frame body 100; and the longitudinal beams 112 are detachably connected to the two crossbeams 111 at both ends. In this embodiment, by providing detachably connected crossbeams 111 and longitudinal beams 112, the frame body 100 can be further disassembled into smaller units, thereby further reducing storage space requirements and lowering after-sales repair and replacement costs.

[0058] like Figure 2 As shown, further, the assembly unit 110 includes a plurality of support connection components 102; both ends of the longitudinal beam 112 are detachably connected to the cross beam 111 through the support connection components 102. Figure 3 and Figure 4 As shown, specifically, the longitudinal beam 112 is detachably connected to the first connection portion 114 of the support and connection assembly 102, and the cross beam 111 is also detachably connected to the first connection portion 114. In this embodiment, the two ends of the longitudinal beam 112 are detachably connected to the cross beam 111 via the support and connection assembly 102. When the cross beam 111 or the longitudinal beam 112 is damaged, only the damaged beam can be removed from the support and connection assembly 102 without removing other intact beams. This facilitates replacement of the damaged beam and reduces after-sales repair and replacement costs.

[0059] In other embodiments, the frame assembly 101 includes two crossbeams 111 and multiple longitudinal beams 112. The crossbeams 111 are spaced apart in the front-to-back direction, and the longitudinal beams 112 are spaced apart between the crossbeams 111 in the left-to-right direction. The ends of the longitudinal beams 112 are fixedly connected to the two crossbeams 111. Specifically, the ends of the longitudinal beams 112 are welded to the two crossbeams 111. In this embodiment, the entire frame assembly 101 serves as the smallest unit, which can increase assembly speed compared to an assembly using the crossbeams 111 and longitudinal beams 112 as the smallest unit.

[0060] like Figures 3 to 5 As shown, in some embodiments, the support connection assembly 102 includes a support portion 113, a first connection portion 114, and a second connection portion 115. The first connection portion 114 and the second connection portion 115 are formed at one end and the other end of the support portion 113, respectively. The first connection portion 114 is connected to the frame assembly 101, and the second connection portion 115 is detachably connected to the adjacent assembly unit 110. In this embodiment, the support portion 113 can support the upper frame assembly 101, forming a first storage space between the two adjacent frame assemblies 101. The first connection portion 114 and the second connection portion 115 provide a mounting base for the two adjacent frame assemblies 101.

[0061] Furthermore, the second connecting portion 115 is detachably connected to the support connecting assembly 102 of the adjacent assembly unit 110. This avoids the need to connect the second connecting portion 115 to the frame assembly 101 of the adjacent assembly unit 110, reducing the amount of processing required for the frame assembly 101. For example, the number of holes punched in the frame assembly 101 can be reduced, preventing an excessive number of mounting holes from affecting the strength of the frame assembly 101. Furthermore, when assembling the frame body 100, the number of assembly parts can be reduced, increasing assembly speed.

[0062] Furthermore, the first connecting portion 114 is detachably connected to the frame assembly 101. That is, for the same assembly unit 110, the frame assembly 101 and the supporting connection assembly 102 of the assembly unit 110 are detachably connected, which facilitates storage and reduces after-sales repair and replacement costs.

[0063] In some embodiments, one of the first connecting portion 114 and the second connecting portion 115 is detachably connected to the frame assembly 101, while the other is detachably connected to the support and connection assembly 102 of the adjacent assembly unit 110. In other words, the detachable connection of the support and connection assemblies 102 of two adjacent assembly units 110 can reduce the processing required for the frame assembly 101. For example, this can reduce the number of holes required to be drilled in the frame assembly 101, thus preventing an excessive number of mounting holes from affecting the strength of the frame assembly 101. Furthermore, when assembling the frame body 100, the number of assembly parts can be reduced, thereby increasing assembly speed.

[0064] like Figure 3 and Figure 4 As shown, the first connecting portion 114 further includes a first horizontal connecting plate formed at one end of the support portion 113, and the first horizontal connecting plate is detachably connected to the frame assembly 101. By providing the first horizontal connecting plate, the contact area between the support connection assembly 102 and the frame assembly 101 can be increased, thereby improving installation stability.

[0065] like Figure 5 As shown, the second connecting portion 115 further includes a first vertical connecting plate 117; the first vertical connecting plate 117 is formed at the other end of the support portion 113, and the first vertical connecting plate 117 is detachably connected to the support connection assembly 102 of the adjacent assembly unit 110. Specifically, the first vertical connecting plate 117 is detachably connected to one end of the support portion 113 of the adjacent support connection assembly 102 away from the frame assembly 101. In other words, the first vertical connecting plate 117 is detachably connected to the outer side surface of the support portion 113 of the adjacent support connection assembly 102 below, facilitating installation and removal.

[0066] like Figure 5 As shown, further, the second connecting portion 115 includes a second horizontal connecting plate 118; the second horizontal connecting plate 118 is formed on the left and right sides of the support portion 113, and the second horizontal connecting plate 118 is detachably connected to the first horizontal connecting plate of the adjacent supporting connecting assembly 102 below.

[0067] Specifically, the first horizontal connecting plate is provided with a longitudinal axis mounting hole, a transverse axis mounting hole, and a first connecting mounting hole. These holes are arranged from the inside out. Screws are installed in the longitudinal axis mounting hole to achieve a removable connection with the longitudinal axis. Screws are installed in the transverse axis mounting hole to achieve a removable connection with the transverse axis. The second horizontal connecting plate 118 is provided with a second connecting mounting hole. The first connecting mounting hole corresponds to the second connecting mounting hole in a one-to-one relationship, and screws are used to achieve a removable connection between the two support connection assemblies 102.

[0068] Specifically, the first vertical connecting plate 117 is provided with a third connecting mounting hole, and the supporting portion 113 is provided with a fourth connecting mounting hole. The third connecting mounting hole corresponds to the fourth connecting mounting hole one by one, and the two supporting connecting assemblies 102 are detachably connected by screws.

[0069] The side close to the frame assembly 101 is the inner side, and the side away from the frame assembly 101 is the outer side.

[0070] like Figure 5 As shown, specifically, the support connection assembly 102 further includes a third connection portion 116 ; the third connection portion 116 is formed on the left side and / or the right side of the support portion 113 , and the third connection portion 116 is detachably connected to the reinforcing rod 121 .

[0071] Specifically, the left side and / or right side of the support portion 113 may also be detachably connected to the reinforcing rod 121 .

[0072] like Figure 1 As shown, further, a pipeline mounting plate 103 is provided between two adjacent left and right support portions 113, and both ends of the pipeline mounting plate 103 are detachably connected to the two adjacent left and right support portions 113. By providing the pipeline mounting plate 103, the battery pack cables can be installed and the cables can be neatly arranged.

[0073] like Figure 1 As shown, in some embodiments, the frame body 100 further includes a reinforcement unit 120. The reinforcement unit 120 is disposed outside the first receiving space and is detachably connected to the assembly unit 110. The reinforcement unit 120 can improve the load-bearing capacity of the frame body 100.

[0074] In addition, the reinforcement unit 120 is located outside the first receiving space, which is convenient for disassembly and avoids occupying the first receiving space.

[0075] Furthermore, the reinforcement unit 120 is detachably connected to the assembly unit 110, and the assembly unit 110 can be locally reinforced according to the stress conditions. Compared with the solution of strengthening the frame body 100 as a whole, it can not only reinforce the assembly unit 110 but also reduce the overall weight.

[0076] like Figure 9 As shown, the reinforcement unit 120 further includes a plurality of reinforcement rods 121. The reinforcement rods 121 are arranged at an angle and are detachably connected to the assembly unit 110. Specifically, the reinforcement rods 121 are detachably connected to the outer side of the assembly unit 110 and are arranged at an angle. The inclined arrangement of the reinforcement rods 121 further enhances the reinforcement effect.

[0077] Furthermore, both ends of the reinforcing rod 121 are detachably connected to the supporting connection components 102 of the two assembly units 110 arranged above and below. Figure 5 As shown, specifically, the support connection assembly 102 further includes a third connection portion 116 ; the third connection portion 116 is formed on the left side and / or the right side of the support portion 113 , and the third connection portion 116 is detachably connected to the reinforcing rod.

[0078] It should be noted that, in this embodiment, the detachable connection may be achieved by bolts and screws, or by other structural parts.

[0079] The reinforcement unit 120 is described in detail below.

[0080] like Figure 1 、 Figures 9 to 11 As shown, in some embodiments, the battery frame assembly further includes a reinforcement unit 120; the reinforcement unit 120 is disposed on the side of the battery frame module and is detachably connected to the battery frame module. It should be noted that the battery frame module includes a frame body 100 and a frame base 200. In other words, the reinforcement unit 120 is disposed on the side of the frame body 100 and the frame base 200 and is detachably connected to the frame body 100 and / or the frame base 200.

[0081] In this embodiment, by providing a battery frame module, an installation base can be provided for installing a battery pack. By providing a reinforcement unit 120, the reinforcement unit 120 can be detachably provided on the outer side of the battery frame module, which not only improves the rigidity of the battery frame module, but also avoids the need to connect the reinforcement unit 120 to the battery frame module by welding, thereby solving the problem of limited welding space and high welding difficulty in the reinforcement structure of the existing battery frame assembly. After the reinforcement unit 120 fails, the reinforcement unit 120 can be removed from the battery frame module for easy maintenance, thereby solving the problem of difficulty in replacing the reinforcement structure of the existing battery frame assembly after failure.

[0082] Exemplarily, the reinforcement unit 120 is detachably disposed on the inner side of the battery frame module.

[0083] Exemplarily, the reinforcement unit 120 is detachably disposed on the outer side of the battery frame module.

[0084] Preferably, the reinforcement unit 120 is detachably mounted on at least one outer side surface of the battery frame module.

[0085] In some embodiments, the reinforcement unit 120 includes a plurality of reinforcement rods 121. The reinforcement rods 121 are tilted and detachably connected to the battery frame module. The tilted reinforcement rods 121 can further improve the rigidity of the battery frame assembly.

[0086] Furthermore, the reinforcing unit 120 is a metal part, specifically, the reinforcing rod 121 is a metal part. Compared with plastic parts, metal parts have stronger reinforcing ability.

[0087] Furthermore, the reinforcement unit 120 is a plate or a casting. Specifically, the reinforcement rod 121 is a plate or a casting. Plates are easier to process. Castings have higher rigidity than plate materials.

[0088] Exemplarily, the reinforcing rod 121 is a steel plate.

[0089] It should be noted that when laying out the reinforcing rods 121, simulation analysis software can be used to simulate and analyze the battery frame module, and the layout plan of the reinforcing rods 121 can be determined based on the simulation analysis results. Specifically, the reinforcing rods 121 are arranged in the stress concentration areas of the battery frame module so that the stress is transferred along the reinforcing rods 121, thereby improving the uniformity of the stress distribution of the battery frame module.

[0090] like Figure 9 and Figure 10 As shown, in some embodiments, the reinforcement unit 120 includes a first reinforcement assembly 122; a plurality of cross-arranged reinforcement rods 121 form the first reinforcement assembly 122. When the first reinforcement assembly 122 is installed in the battery frame module, the reinforcement rods 121 of the first reinforcement assembly 122 and the battery frame module form multiple triangles. Compared with the solution of reinforcing with a single reinforcement rod 121, the solution of reinforcing with the first reinforcement assembly 122 can further improve the rigidity of the battery frame assembly.

[0091] Furthermore, the reinforcing rods 121 forming the first reinforcing assembly 122 are detachably connected to each other, so that when the reinforcing rods 121 are damaged, they can be easily replaced.

[0092] For example, two cross-arranged reinforcing rods 121 form a first reinforcing assembly 122; the middle and both ends of the reinforcing rods 121 forming the first reinforcing assembly 122 are respectively provided with mounting holes, such as Figure 9 As shown, the mounting holes at both ends are used for detachable connection with the battery frame module through fasteners. The mounting holes in the middle are used for detachable connection with the cross-arranged reinforcement rods 121 through fasteners.

[0093] It can be understood that the reinforcing rods 121 forming the first reinforcing assembly 122 are arranged at an angle.

[0094] like Figure 9 and Figure 10As shown, in some embodiments, multiple reinforcing rods 121 arranged in a vertical direction form a second reinforcing assembly 123; adjacent reinforcing rods 121 have opposite inclinations. By arranging reinforcing rods 121 in a vertical direction, it is possible to reinforce battery frame modules at different heights. Furthermore, reinforcing rods 121 can be appropriately added or removed based on the height of the battery frame modules to accommodate battery frame modules of varying heights, improving versatility.

[0095] Specifically, two adjacent reinforcing rods 121 are arranged at intervals, which can reduce the weight of the battery frame assembly while ensuring the reinforcing effect.

[0096] Specifically, the opposite ends of two adjacent reinforcing rods 121 are connected so that the second reinforcing assembly 123 forms a V-shape or a W-shape, which can further improve the reinforcing effect.

[0097] In some embodiments, the upper end of the battery frame module has an opening for allowing the battery pack to enter and exit the battery frame module. The front side, rear side, left side and right side of the battery frame module are all detachably installed with reinforcement units 120.

[0098] In this embodiment, the upper end opening of the battery frame module allows the battery pack to be installed in the battery frame module by hoisting. By installing the reinforcement unit 120 on all four sides, the reinforcement effect of the battery frame module can be further improved compared to the existing solution of installing the reinforcement structure on two sides.

[0099] The existing battery frame assembly has an opening on one side for the battery pack to enter and exit. Therefore, the four sides of the existing battery frame assembly are not all reinforced, which results in poor reinforcement of the battery frame assembly. In this embodiment, because the battery frame module is open at the top, the reinforcement unit 120 can be installed on all four sides of the battery frame module, thus achieving a better reinforcement effect for the battery frame assembly of this embodiment.

[0100] Specifically, the first reinforcement assembly 122 is installed on both the left side and the right side of the battery frame module to strengthen the left side and the right side.

[0101] Specifically, the arrangement of the reinforcing rods 121 on the left and right sides of the battery frame module is the same. In other words, the reinforcing rods 121 on the left and right sides of the battery frame module are symmetrically arranged, making the battery frame assembly more beautiful.

[0102] Specifically, the arrangement of the reinforcing bars 121 on the front and rear sides of the battery frame module is the same. In other words, the reinforcing bars 121 on the front and rear sides of the battery frame module are symmetrically arranged, making the battery frame assembly more beautiful.

[0103] like Figure 6As shown, a specific embodiment of the second aspect of the present invention provides a battery frame assembly. The battery frame assembly includes a frame body 100 of any of the above embodiments.

[0104] Because the battery frame assembly of this embodiment includes the frame body 100 of any of the above embodiments, it has at least the above advantages, which will not be described in detail here.

[0105] Furthermore, the battery frame assembly further includes a frame base 200 , which is disposed below the frame body 100 and connected to the bottom assembly unit 110 . The frame base 200 can mount the battery frame assembly on the vehicle beam 300 .

[0106] In some embodiments, the frame base 200 is welded to the bottom assembly unit 110 to improve assembly efficiency.

[0107] In other embodiments, the frame base 200 is detachably connected to the bottom assembly unit 110. By making the frame body 100 and the frame base 200 detachable, welding can be avoided, eliminating the need for polishing, improving production efficiency, and reducing production costs. When storing the battery frame assembly, the frame body 100 and the frame base 200 can also be separated, further reducing storage space pressure.

[0108] In some embodiments, the frame base 200 and the assembly unit 110 at the bottom form a second storage space for storing battery packs. By forming the second storage space between the frame body 100 and the frame base 200, the utilization rate of the frame base 200 can be improved.

[0109] The following combination Figure 7 and Figure 8 The frame base 200 will be described in detail.

[0110] like Figure 7 As shown, in some embodiments, the frame base 200 includes a bottom bracket frame 210 and a bottom bracket support unit 220. The bottom bracket frame 210 is used to mount the battery pack; the bottom bracket support unit 220 is detachably connected to the bottom bracket frame 210 and is used to mount the bottom bracket frame 210 to the vehicle beam 300.

[0111] In this embodiment, by providing a bottom bracket support unit 220 that is detachably connected to the bottom bracket frame 210, not only can the battery frame assembly be installed on the vehicle beam 300, but the bottom bracket frame 210 and the bottom bracket support unit 220 can also be connected by welding, thereby eliminating the polishing process after welding, reducing production costs, and improving production efficiency. When storing the battery frame assembly, the bottom bracket frame 210 and the bottom bracket support unit 220 can be separated, thereby reducing storage space pressure and solving the problems of low production efficiency, high cost, and high storage space pressure existing in existing battery frame assemblies.

[0112] In some embodiments, the base support unit 220 includes two base support assemblies 201; both base support assemblies 201 are used to be detachably mounted on the vehicle frame 300; along the width direction of the vehicle frame 300, the two base support assemblies 201 are spaced apart, and the position of at least one base support assembly 201 on the base frame 210 is adjustable.

[0113] In this embodiment, by arranging two bottom support assemblies 201 at intervals along the width direction of the vehicle beam 300, and the position of at least one bottom support assembly 201 on the bottom support frame 210 is adjustable, the distance between the two bottom support assemblies 201 can be adjusted according to the width of the vehicle beam 300, so that the bottom support unit 220 can adapt to vehicle beams 300 of different widths, so that the battery frame assembly can be installed on vehicle beams 300 of different widths, thereby improving the versatility of the battery frame assembly.

[0114] It should be noted that the width direction of the vehicle beam 300 can be the left-right direction or the front-back direction. Figure 6 and Figure 7 As shown in , the width direction of the vehicle beam 300 is the left-right direction, and the length direction of the vehicle beam 300 is the front-back direction. In other embodiments, the width direction of the vehicle beam 300 is the front-back direction, and the length direction of the vehicle beam 300 is the left-right direction.

[0115] Furthermore, the bottom bracket frame 210 has multiple connection holes along the width of the vehicle beam 300; the bottom bracket support assembly 201 is connected to at least one of the connection holes via a fastener. In this embodiment, the spacing between the two bottom bracket support assemblies 201 can be adjusted by adjusting the mounting position of the fastener relative to the vehicle beam 300, allowing the bottom bracket support unit 220 to adapt to vehicle beams 300 of varying widths. This allows the battery frame assembly to be installed on vehicle beams 300 of varying widths, thereby improving the versatility of the battery frame assembly.

[0116] Furthermore, the bottom support assembly 201 includes multiple bottom support members 221; along the length direction of the vehicle beam 300, multiple bottom support members 221 are arranged at intervals, and the upper ends of the bottom support members 221 are detachably connected to the bottom support frame 210 for installing the bottom support frame 210 on the vehicle beam 300.

[0117] In this embodiment, a plurality of bottom support members 221 are arranged at intervals along the length direction of the vehicle frame 300, and the bottom support members 221 are used to install the bottom support frame 210 on the vehicle frame 300. Compared with the existing solution of installing the bottom support frame on the vehicle frame 300 by connecting sub-beams, this embodiment can reduce the overall weight of the frame base 200, thereby reducing the weight of the battery frame assembly.

[0118] It should be noted that, “a plurality” refers to at least two. In other words, the bottom bracket support assembly 201 includes at least two bottom bracket support members 221 .

[0119] Exemplarily, the bottom bracket support assembly 201 includes two bottom bracket support members 221 ; the two bottom bracket support members 221 are spaced apart along the length direction of the vehicle beam 300 .

[0120] like Figure 8 As shown, the bottom bracket support member 221 further includes a bottom bracket connector 2211 and a support connector 2212. The bottom bracket connector 2211 is detachably connected to the bottom bracket frame 210. The upper end of the support connector 2212 is connected to the bottom bracket connector 2211, and the side surfaces of the support connector 2212 adjacent to the bottom bracket connector 2211 have two connecting portions 2215; along the length direction of the vehicle beam 300, the two connecting portions 2215 are respectively arranged on either side of the bottom bracket connector 2211, and the connecting portions 2215 are used for detachable connection to the vehicle beam 300.

[0121] In this embodiment, by providing two connecting portions 2215 on the side surfaces adjacent to the support connector 2212 and the bottom bracket connector 2211 along the length direction of the vehicle beam 300, the bottom bracket support members 221 can be used alternately in the front-to-rear direction. In other words, in the front-to-rear direction, that is, along the length direction of the vehicle beam 300, bottom bracket support members 221 of the same structure can be used to connect the bottom bracket frame 210 to the vehicle beam 300, thereby improving the versatility of the bottom bracket support unit 220.

[0122] Specifically, the connecting portion 2215 includes a plurality of mounting holes, and the vehicle frame 300 is provided with corresponding mounting holes, and the bottom bracket support member 221 is detachably connected to the vehicle frame 300 through fasteners.

[0123] Furthermore, the bottom support connector 2211 includes a first bottom support connector portion 2213 and a second bottom support connector portion 2214. Along the width direction of the vehicle frame 300, the first bottom support connector portion 2213 and the second bottom support connector portion 2214 are respectively arranged on both sides of the support connector 2212 and are both connected to the support connector 2212. The first bottom support connector portion 2213 and / or the second bottom support connector portion 2214 are connected to at least one connection hole via a fastener.

[0124] In this embodiment, by respectively providing a first bottom support connection portion 2213 and a second bottom support connection portion 2214 on both sides of the support connector 2212 along the width direction of the vehicle beam 300, the bottom support members 221 arranged along the width direction of the vehicle beam 300 can be made universal, thereby improving the versatility of the bottom support members 221.

[0125] Specifically, the upper end of the support connecting member 2212 is bent to the left to form a first bottom supporting connection portion 2213, and the upper end of the support connecting member 2212 is bent to the right to form a second bottom supporting connection portion 2214. The upper side surfaces of the first bottom supporting connection portion 2213 and the second bottom supporting connection portion 2214 are flush, thereby improving the strength of the bottom supporting member 221.

[0126] Preferably, the bottom bracket support member 221 is a casting, that is, the support connecting member 2212, the first bottom bracket connecting portion 2213 and the second bottom bracket connecting portion 2214 are integrally formed.

[0127] Specifically, the first base connecting portion 2213 has mounting holes spaced apart along the width direction of the vehicle frame. The mounting holes are used to set fastening screws, which are threadedly assembled in the connecting holes and the mounting holes to detachably connect the first base connecting portion 2213 to the base frame 210.

[0128] Specifically, the second base connecting portion 2214 also has installation holes spaced apart along the width direction of the vehicle frame, and the installation holes are used to set fastening screws, which are threadedly assembled in the connection holes and the installation holes to detachably connect the second base connecting portion 2214 to the base frame 210.

[0129] By detachably connecting the first base supporting portion 2213 and the second base supporting portion 2214 to the base supporting frame 210 , the contact area between the base supporting frame 210 and the base supporting member 221 can be increased, thereby improving the supporting stability and installation stability of the base supporting frame 210 .

[0130] like Figure 7As shown, in some other embodiments, the bottom bracket support unit 220 further includes an adjustment assembly 202; one end of the adjustment assembly 202 is connected to the bottom bracket frame 210, and the other end is detachably connected to the bottom bracket support assembly 201, and is used to adjust the distance between the two bottom bracket support assemblies 201. The provision of the adjustment assembly 202 can improve the convenience of adjusting the two bottom bracket support assemblies 201.

[0131] Furthermore, the adjustment assembly 202 includes a plurality of first adjustment members and a second adjustment member. The plurality of first adjustment members are spaced apart on the bottom bracket frame 210 along the width direction of the vehicle beam 300. One end of the second adjustment member is detachably connected to the first adjustment member, and the other end is connected to the bottom bracket support assembly 201.

[0132] In this embodiment, a plurality of first adjusting members are arranged at intervals along the width direction of the vehicle beam 300, and a second adjusting member is provided which is detachably connected to the first adjusting member, and the second adjusting member is also connected to the bottom bracket support assembly 201. By adjusting the first adjusting member connected to the second adjusting member, the distance between the two bottom bracket support assemblies 201 can be changed, so that the two bottom bracket support assemblies 201 can be adapted to vehicle beams 300 of different widths, thereby improving the overall versatility of the battery frame assembly.

[0133] Specifically, a plurality of first adjustment mounting holes are defined in the bottom bracket mounting frame 211 of the bottom bracket frame 210; these first adjustment mounting holes are spaced apart along the width of the vehicle beam 300. Accordingly, second adjustment mounting holes are defined in the bottom bracket connector 2211 of the bottom bracket support assembly 201. By aligning the second adjustment mounting holes with first adjustment mounting holes at different positions and fastening with screws, the bottom bracket support assembly 201 and the bottom bracket mounting frame 211 can be detachably connected. This allows the entire battery frame assembly to adapt to vehicle beams 300 of varying widths, thereby improving the versatility of the battery frame assembly.

[0134] like Figure 7 As shown, in some embodiments, the base mounting frame 211 includes multiple base cross beams and multiple base longitudinal beams. The multiple base cross beams are spaced apart along the length of the vehicle frame 300. The base cross beams are detachably connected to the upper ends of the base support units 220. Multiple base longitudinal beams are spaced apart along the width of the vehicle frame 300, with each end of the base longitudinal beam connected to the two base cross beams. Specifically, the ends of the base longitudinal beams are welded to the base longitudinal beams to improve strength.

[0135] like Figure 7As shown, the bottom bracket frame 210 further includes a bottom bracket mounting frame 211 and a mounting crossbeam 212. The bottom bracket mounting frame 211 has a removable bottom bracket support unit 220 attached to its underside. Multiple mounting crossbeams 212 are spaced apart along the length of the vehicle frame 300, connecting to the bottom bracket mounting frame 211 for mounting the battery pack. The bottom bracket mounting frame 211 provides a mounting base for the bottom bracket support unit 220.

[0136] By setting up the installation beam 212, a mounting base can be provided for the battery pack, so that the battery pack and the bottom bracket support unit 220 can be installed on different structural parts respectively. Compared with the solution of installing the bottom bracket support unit 220 and the battery pack on the same structural part, this embodiment can reduce material usage and reduce material costs.

[0137] Exemplarily, the bottom supporting cross beam and the bottom supporting longitudinal beam are both made of pipes to ensure the torsional resistance of the bottom supporting mounting frame 211 .
