In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0037] Combine the following Figures 1 to 11 The battery frame assembly of the present invention is described in detail.

[0038] like Figure 6 As shown, a specific embodiment of the first aspect of the present invention provides a battery frame assembly. The battery frame assembly includes a frame body 100 and a frame base 200 .

[0039] The frame body 100 includes a plurality of assembly units 110; the plurality of assembly units 110 are stacked in sequence in the up-down direction, and the adjacent assembly units 110 are detachably connected, and the assembly units 110 have a first storage space; the first storage space is used to store the battery pack. The frame base 200 is disposed below the frame body 100, and the frame base 200 is connected to the assembly unit 110 at the bottom.

[0040] In this embodiment, by stacking a plurality of assembly units 110 in sequence in the up-down direction, and adjacent assembly units 110 can be detachably connected, it is possible to avoid welding to produce the frame body 100, eliminate the welding and polishing process, improve the production efficiency of the frame body 100, and reduce the production cost; and when storing the frame body 100, the plurality of assembly units 110 can be disassembled, which can reduce the storage space pressure, thereby reducing the inventory pressure and transportation pressure. The frame base 200 can provide an installation foundation for the frame body 100, so that the frame body 100 can be installed on the vehicle beam 300.

[0041] It should be noted that "assembly unit 110 has a first storage space" can be interpreted in at least two ways. The first interpretation is that the assembly unit 110 itself has a first storage space inside, for example, the assembly unit 110 is a frame structure, and the frame structure has a first storage space inside. The second interpretation is that the first storage space is formed when two assembly units 110 are detachably assembled together. In other words, when two assembly units 110 adjacent to each other are assembled together, the two assembly units 110 adjacent to each other are spliced ​​to form the first storage space.

[0042] Exemplarily, the upper end of the first storage space has an opening, and the opening is used for the battery pack to enter and exit the first storage space, so as to facilitate the installation of the battery pack to the first storage space by hoisting, which can reduce the difficulty of battery assembly and improve the convenience of battery assembly.

[0043] In some embodiments, the frame base 200 is welded to the bottom assembly unit 110 to improve assembly efficiency.

[0044] In some other embodiments, the frame base 200 is detachably connected to the assembly unit 110 at the bottom. By detachably connecting the frame body 100 and the frame base 200, it is possible to avoid welding the frame body 100 and the frame base 200, eliminating the need for grinding at this point, 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.

[0045] In some embodiments, the frame base 200 and the assembly unit 110 at the bottom form a second storage space; the second storage space is used to store the battery pack. 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.

[0046] It should be noted that in this embodiment, a plurality refers to at least two. In other words, the frame body 100 of this embodiment includes at least two assembly units 110 .

[0047] In some embodiments, the assembly unit 110 includes a frame assembly 101 and a support and connection assembly 102; the frame assemblies 101 of two adjacent assembly units 110 form a first storage space; the support and connection assembly 102 is disposed on the frame assembly 101; and the frame assemblies 101 of two adjacent assembly units 110 are detachably connected via the support and connection assembly 102. In other words, when the assembly units 110 are stacked in the up-down direction, the frame assemblies 101 of two adjacent assembly units 110 form a first storage space, one end of the support and connection assembly 102 of the same assembly unit 110 is fixedly connected or detachably connected to the frame assembly 101 of the 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.

[0048] In this embodiment, by providing the frame assembly 101, a mounting base can be provided for the battery pack to ensure the mounting stability of the battery pack. By providing the support connection assembly 102, the frame assemblies 101 of two adjacent assembly units 110 can be detachably connected to ensure the detachability of the two adjacent assembly units 110.

[0049] Exemplarily, one end of the support connection assembly 102 of the same assembly unit 110 is welded to the frame assembly 101 of the assembly unit 110, and the other end of the support connection assembly 102 is detachably connected to the frame assembly 101 of the adjacent assembly unit 110. Welding the support connection assembly 102 of the same assembly unit 110 to the frame assembly 101 can improve the assembly efficiency of the frame body 100 and improve the smoothness of the assembly line operation.

[0050] Exemplarily, one end of the support connection assembly 102 of the same assembly unit 110 is detachably connected to the frame assembly 101 of the assembly unit 110, and the other end of the support connection assembly 102 is detachably connected to the frame assembly 101 of the adjacent assembly unit 110. By detachably connecting one end of the support connection assembly 102 of the same assembly unit 110 to the frame assembly 101 of the assembly unit 110, the welding and grinding process is eliminated, the manufacturing hours of the frame body 100 are reduced, the manufacturing efficiency of the frame body 100 is improved, and the inventory and transportation pressure can be further reduced.

[0051] It is understandable that the detachable connection method includes but is not limited to the fastening connection of screws. Specifically, mounting holes are opened on the two workpieces that need to be detachably connected, screws are installed in the mounting holes, and fixed with nuts.

[0052] like Figure 2 As shown, in some embodiments, the frame assembly 101 includes a plurality of cross beams 111 and a plurality of longitudinal beams 112. The cross beams 111 extend along the length direction of the frame body 100; the plurality of cross beams 111 are arranged at intervals along the width direction of the frame body 100; the plurality of longitudinal beams 112 are located between two cross beams 111 and are arranged at intervals along the length direction of the frame body 100; the two ends of the longitudinal beam 112 are detachably connected to the two cross beams 111, respectively. In this embodiment, by providing detachably connected cross beams 111 and longitudinal beams 112, the frame body 100 can be further split into smaller units, thereby further reducing the storage space pressure and reducing the cost of after-sales repair and replacement parts.

[0053] like Figure 2 As shown, further, the assembly unit 110 includes a plurality of supporting connection components 102; the two ends of the longitudinal beam 112 are detachably connected to the cross beam 111 through the supporting connection components 102 in a one-to-one correspondence. Figure 3 and Figure 4 As shown, specifically, the longitudinal beam 112 is detachably connected to the first connection portion 114 of the support 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 through the support connection assembly 102 in a one-to-one correspondence. When the cross beam 111 or the longitudinal beam 112 is damaged, only the damaged beam can be removed from the support connection assembly 102 without removing other undamaged beams, which facilitates the replacement of the damaged beam and reduces the cost of after-sales repair and replacement parts.

[0054] In some other embodiments, the frame assembly 101 includes two cross beams 111 and a plurality of longitudinal beams 112; the two cross beams 111 are arranged at intervals in the front-to-back direction; the longitudinal beams 112 are arranged at intervals between the two cross beams 111 in the left-to-right direction, and the two ends of the longitudinal beams 112 are respectively fixedly connected to the two cross beams 111. Specifically, the two ends of the longitudinal beams 112 are welded to the two cross beams 111. In this embodiment, the frame assembly 101 as a whole is the smallest unit, which can increase the assembly speed compared to the smallest assembly unit with the cross beams 111 and the longitudinal beams 112.

[0055] 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 in a one-to-one correspondence; the first connection portion 114 is connected to the frame assembly 101, and the second connection portion 115 is connected to the adjacent assembly unit 110. In this embodiment, by providing the support portion 113, the frame assembly 101 can be supported, so that a first storage space is formed between two frame assemblies 101 adjacent to each other. By providing the first connection portion 114 and the second connection portion 115, an installation foundation can be provided for two frame assemblies 101 adjacent to each other.

[0056] Furthermore, the first connection portion 114 is detachably connected to the frame assembly 101. That is, for the same assembly unit 110, the frame assembly 101 and the support connection assembly 102 of the assembly unit 110 are detachably connected, which is convenient for storage and reduces the cost of after-sales maintenance and replacement parts.

[0057] Furthermore, the second connection portion 115 is detachably connected to the adjacent assembly unit 110. In other words, the two adjacent assembly units 110 are detachably connected via one supporting connection assembly 102.

[0058] Exemplarily, the first connection portion 114 is fixedly connected to the corresponding frame assembly 101 , and the second connection portion 115 is detachably connected to the corresponding frame assembly 101 .

[0059] In some embodiments, one of the first connection portion 114 and the second connection portion 115 is detachably connected to the frame assembly 101, and the other is detachably connected to the support connection assembly 102 of the adjacent assembly unit 110. In other words, the support connection assemblies 102 of two adjacent assembly units 110 are detachably connected, which can reduce the processing of the frame assembly 101, for example, it can reduce the drilling of the frame assembly 101, and avoid that too many mounting holes affect the strength of the frame assembly 101. In addition, when assembling the frame body 100, the number of assembly parts can be reduced, and the assembly speed can be improved.

[0060] like Figure 3 and Figure 4 As shown, further, the first connecting portion 114 includes a first horizontal connecting plate, which is formed at the upper end of the supporting portion 113 and is detachably connected to the frame assembly 101. By providing the first horizontal connecting plate, the contact area between the supporting connecting assembly 102 and the frame assembly 101 can be increased, thereby improving the installation stability.

[0061] like Figure 5 As shown, further, the second connection portion 115 includes a first vertical connection plate 117; the first vertical connection plate 117 is formed at the lower end of the support portion 113, and the first vertical connection plate 117 is detachably connected to the adjacent support connection assembly 102. Specifically, the first vertical connection plate 117 is detachably connected to the upper end of the support portion 113 of the adjacent support connection assembly 102 away from the frame assembly 101, that is, the first vertical connection plate 117 is detachably connected to the outer side surface of the support portion 113 of the adjacent support connection assembly 102 below, which is convenient for installation and disassembly.

[0062] Furthermore, the second connection portion 115 includes a second horizontal connection plate 118 ; the second horizontal connection plate 118 is formed on the left and right sides of the support portion 113 , and the second horizontal connection plate 118 is detachably connected to the first horizontal connection plate of the support connection assembly 102 adjacent thereto.

[0063] 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; the longitudinal axis mounting hole, the transverse axis mounting hole and the first connecting mounting hole are arranged from the inside to the outside. A screw is installed in the longitudinal axis mounting hole to achieve a detachable connection with the longitudinal axis. A screw is installed in the transverse axis mounting hole to achieve a detachable connection with the transverse axis. The second horizontal connecting plate 118 is provided with a second connecting mounting hole, and the first connecting mounting hole corresponds to the second connecting mounting hole one by one, and the detachable connection of the two supporting connecting components 102 is achieved by screws.

[0064] Specifically, the first vertical connecting plate 117 is provided with a third connecting mounting hole, 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 detachable connection of the two supporting connecting assemblies 102 is achieved by screws.

[0065] 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.

[0066] 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 .

[0067] Specifically, the left side surface and / or the right side surface of the support portion 113 may also be detachably connected to the reinforcing rod 121 .

[0068] like Figure 1 As shown, further, a pipeline installation plate 103 is arranged between two adjacent support parts 113 on the left and right, and both ends of the pipeline installation plate 103 are detachably connected to the two adjacent support parts 113 on the left and right. By setting the pipeline installation plate 103, the installation of the cables of the battery pack can be realized, so that the cables are neat.

[0069] The strengthening unit 120 is described in detail below.

[0070] like Figure 1 , Figures 9 to 11 As shown, in some embodiments, the battery frame assembly further includes a reinforcing unit 120; the reinforcing unit 120 is disposed on the side of the battery frame module, and the reinforcing unit 120 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 reinforcing 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.

[0071] In this embodiment, by setting up a battery frame module, an installation foundation can be provided for installing a battery pack. By setting up a reinforcement unit 120, the reinforcement unit 120 can be detachably arranged on the outer side of the battery frame module, which can not only improve the rigidity of the battery frame module, but also avoid connecting the reinforcement unit 120 to the battery frame module by welding, thereby solving the problem that the reinforcement structure of the existing battery frame assembly has limited welding space and high welding difficulty. After a failure of the reinforcement unit 120, the reinforcement unit 120 can be removed from the battery frame module for easy maintenance, thereby solving the problem that the reinforcement structure of the existing battery frame assembly is difficult to replace after a failure.

[0072] Exemplarily, the reinforcement unit 120 is detachably disposed on the inner side of the battery frame module.

[0073] Exemplarily, the reinforcement unit 120 is detachably disposed on the outer side of the battery frame module.

[0074] Preferably, the reinforcing unit 120 is detachably mounted on at least one outer side surface of the battery frame module.

[0075] In some embodiments, the reinforcing unit 120 includes a plurality of reinforcing rods 121; the reinforcing rods 121 are arranged obliquely and are detachably connected to the battery frame module. The rigidity of the battery frame assembly can be further improved by the inclined reinforcing rods 121.

[0076] Furthermore, the reinforcing unit 120 is a metal part, and specifically, the reinforcing rod 121 is a metal part. Compared with plastic parts, metal parts have stronger reinforcing ability.

[0077] Further, the reinforcing unit 120 is a plate or a casting. Specifically, the reinforcing rod 121 is a plate or a casting. The plate is easy to process. The rigidity of the casting is higher than that of the plate.

[0078] Exemplarily, the reinforcing rod 121 is a steel plate.

[0079] It should be noted that when arranging the reinforcing rods 121, simulation analysis software can be used to perform simulation analysis on the battery frame module, and the arrangement scheme of the reinforcing rods 121 can be determined according to the simulation analysis results. Specifically, the reinforcing rods 121 are arranged in the stress concentration area of ​​the battery frame module so that the stress is transmitted along the reinforcing rods 121, thereby improving the uniformity of the stress distribution of the battery frame module.

[0080] like Fig. 9 and Fig.10 As shown, in some embodiments, the reinforcement unit 120 includes a first reinforcement component 122; a plurality of cross-arranged reinforcement rods 121 form the first reinforcement component 122. When the first reinforcement component 122 is installed on the battery frame module, the reinforcement rods 121 of the first reinforcement component 122 and the battery frame module form a plurality of triangles. Compared with the solution of reinforcement by a single reinforcement rod 121, the solution of reinforcement by the first reinforcement component 122 can further improve the rigidity of the battery frame assembly.

[0081] 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, it is convenient to replace them.

[0082] Exemplarily, 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 Fig. 9 As shown, the mounting holes at both ends are used to be detachably connected to the battery frame module through fasteners. The mounting holes in the middle are used to be detachably connected to the cross-arranged reinforcing rods 121 through fasteners.

[0083] It can be understood that the reinforcing rods 121 forming the first reinforcing assembly 122 are arranged at an angle.

[0084] like Fig. 9 and Fig.10As shown, in some embodiments, a plurality of reinforcing rods 121 arranged in the up-down direction form a second reinforcing assembly 123; the inclination directions of two adjacent reinforcing rods 121 are opposite. By arranging reinforcing rods 121 in the up-down direction, different heights of the battery frame module can be reinforced. In addition, the reinforcing rods 121 can be appropriately increased or decreased according to the height of the battery frame module to adapt to battery frame modules of different heights and improve versatility.

[0085] 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.

[0086] 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.

[0087] 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, and the front side, rear side, left side and right side of the battery frame module are all detachably installed with a reinforcement unit 120.

[0088] In this embodiment, the battery pack can be installed on the battery frame module by hoisting by opening the upper end of the battery frame module. By installing the reinforcement unit 120 on all four sides, the reinforcement effect of the battery frame module can be further improved compared with the existing solution of installing the reinforcement structure on two sides.

[0089] One side of the existing battery frame assembly has an opening for the battery pack to enter and exit, so the four sides of the existing battery frame assembly are not all reinforced, which results in a poor reinforcement effect 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 the four sides of the battery frame module, so the reinforcement effect of the battery frame assembly of this embodiment is better.

[0090] Specifically, the first reinforcing assembly 122 is installed on both the left side and the right side of the battery frame module, so as to strengthen the left side and the right side.

[0091] 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.

[0092] Specifically, the arrangement of the reinforcing bars 121 on the front side and the rear side of the battery frame module is the same. In other words, the reinforcing bars 121 on the front side and the rear side of the battery frame module are symmetrically arranged, making the battery frame assembly more beautiful.

[0093] The frame base 200 is described in detail below.

[0095] 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 also the bottom bracket frame 210 and the bottom bracket support unit 220 can be connected by welding, and the grinding process after welding is eliminated, thereby reducing the manufacturing cost and improving the manufacturing efficiency. When storing the battery frame assembly, the bottom bracket frame 210 and the bottom bracket support unit 220 can be separated, thereby reducing the storage space pressure and solving the problems of low manufacturing efficiency, high cost, and high storage space pressure in the existing battery frame assembly.

[0096] In some embodiments, the base support unit 220 includes two base support assemblies 201; both base support assemblies 201 are used to be detachably installed on the vehicle frame 300; along the width direction of the vehicle frame 300, the two base support assemblies 201 are arranged at intervals, and the position of at least one base support assembly 201 on the base frame 210 is adjustable.

[0097] In this embodiment, two bottom support assemblies 201 are arranged 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.

[0098] 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 some 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.

[0099] Furthermore, the bottom bracket frame 210 is provided with a plurality of connection holes along the width direction of the vehicle beam 300; the bottom bracket support assembly 201 is connected to at least one connection hole through a fastener. In this embodiment, the spacing distance between the two bottom bracket support assemblies 201 can be adjusted by adjusting the installation position of the fastener relative to the vehicle beam 300, so that the bottom bracket support unit 220 can be adapted 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.

Compared with the existing solution of installing the bottom support frame on the vehicle beam 300 by connecting the sub-beam, this embodiment can reduce the overall weight of the frame base 200, thereby reducing the weight of the battery frame assembly.

[0109] 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, and the upper side surfaces of the first bottom supporting connection portion 2213 and the second bottom supporting connection portion 2214 are flush, so as to improve the strength of the bottom supporting member 221.
