[0063] Figure 3 The structure of the battery pack 210 in the embodiment is shown in the schematic view.

[0064] Reference Figure 3 The battery pack 210 includes a shell and battery cells arranged inside the shell. The shell includes a shell body and a bottom plate 2111. The shell body is hollow inside and has an opening at the bottom. The bottom plate 2111 is arranged at the opening of the shell body and is fixedly connected to the shell body.

The flange protrudes outward from the bottom of the main body part in the circumferential direction. The flange is fixedly connected to the bottom plate 2111.

[0066] In the embodiment, the edge 2101 of the battery pack 210 is provided with multiple perforations 2102 at intervals in the circumferential direction. Specifically, the edge 2101 of the battery pack 210 refers to the flange and the part of the bottom plate 2111 covered by the vertical projection of the flange. The perforations 2102 include first holes arranged on the flange and second holes arranged on the bottom plate 2111.

[0067] The battery cluster mounting rack 100 is used to mount and support the battery cluster.

[0068] Figure 4 Figure 1 is a structural schematic diagram of a battery cluster mounting rack 100 in the embodiment.

[0069] Reference Figure 1 , Figure 2 , Figure 4 The battery cluster mounting rack 100 includes a frame 1 and a plurality of mounting assemblies 2. One side of the frame 1 is open. The plurality of mounting assemblies 2 are connected to the inside of the frame 1 in vertical intervals, and each mounting assembly 2 includes a support frame 21, two first limiting members 22, and two pressing members 24. The support frame 21 is connected to the inside of the frame 1, and the support frame 21 is formed with a receiving groove for receiving a battery pack 210. Each first limiting member 22 is connected to one of the two lateral sides of the battery pack 210. Each first limiting member 22 has an inclined surface. The two pressing members 24 are arranged on the support frame 21 in lateral intervals, and the two pressing members 24 are used to abut the lateral sides of the battery pack 210. Each pressing member 24 has a vertical interval between the bottom wall of the support frame 21 and the pressing member 24, and each pressing member 24 is in pressing fit with a first limiting member 22 to press the battery pack 210 on the support frame 21. Each pressing member 24 has a guide surface, and the guide surface is inclined to guide the movement of the inclined surface when the battery pack 210 is installed or removed.

[0070] In the embodiment, a receiving groove is formed on the support frame 21 to preliminarily receive and limit the battery pack 210. Furthermore, the two pressing members 24 are arranged on the support frame 21 in lateral intervals, and the two pressing members 24 can abut the lateral sides of the battery pack 210 to further abut and limit the battery pack 210. Meanwhile, each pressing member 24 has a vertical interval between the bottom wall of the support frame 21 and the pressing member 24, and the interval can be used for the bottom edge 2101 of the battery pack 210 to pass through. Then, each pressing member 24 can correspond to and be in pressing fit with the first limiting member 22 connected to one lateral side of the battery pack 210 to apply a downward pressure to the battery pack 210. In this way, the battery pack 210 can be pressed vertically on the support frame 21, and the battery pack 210 can be limited and fixed in the vertical direction. This can avoid displacement of the battery pack 210 during movement, and can more effectively ensure the safety and stability of the battery pack 210.

[0071] Furthermore, each first limiting member 22 has an inclined surface, and an inclined guide surface is arranged on each pressing member 24. When the battery pack 210 moves along the bottom wall of the support frame 21 to a position where the first limiting member 22 is below the pressing member 24 and continues to move, the guide surface and the inclined surface 243 cooperate to guide the movement of the inclined surface. In this way, the battery pack 210 can be prevented from deviating from the direction, and the smoothness of the movement of the first limiting member 22 relative to the pressing member 24 can be improved.

[0072] For the convenience of description, it is defined that the opening direction of the frame 1 is longitudinal, and the direction perpendicular to the longitudinal direction is transverse in the same horizontal plane.

[0073] In this embodiment, the frame 1 is opened on one longitudinal side, so as to facilitate the placement and installation of the battery pack 210 in the frame 1, or facilitate the disassembly and removal of the battery pack 210 from the frame 1.

[0074] The frame 1 includes a plurality of columns 11, which are spaced and distributed in the circumferential direction and form a cuboid structure with an opening on one longitudinal side. Exemplarily, the plurality of columns 11 can be divided into two column 11 groups, which are spaced and distributed in the transverse direction, and each column 11 group includes at least two columns 11 spaced in the longitudinal direction.

[0075] The plurality of mounting assemblies 2 are spaced and connected to the inside of the frame 1 in the vertical direction, each mounting assembly 2 is used to mount a battery pack 210, and the plurality of mounting assemblies 2 are cooperatively arranged in the vertical direction to achieve the arrangement of the plurality of battery packs 210 in the vertical direction, which can effectively improve the space utilization in the mobile device. In addition, the plurality of mounting assemblies 2 spaced and distributed in the vertical direction can also achieve the spaced distribution of the plurality of battery packs 210 in the vertical direction, thereby facilitating the heat dissipation of each battery pack 210 and improving the safety and reliability of the battery pack 210.

[0076] Figure 5 The structure of the mounting assembly 2 in this embodiment is shown in the schematic view.

[0077] Reference Figure 4 and Figure 5 The mounting assembly 2 includes a support frame 21, two first limiting members 22, and two pressure connecting members 24.

[0078] The support frame 21 is connected to the inside of the frame 1, and the support frame 21 forms a receiving groove for receiving the battery pack 210. Specifically, the support frame 21 is connected between the plurality of columns 11.

[0079] The support frame 21 includes two main beams 211 and a plurality of support beams 212. The two main beams 211 and the plurality of support beams 212 form a receiving groove with an opening on one longitudinal side, and the opening direction of the receiving groove is the same as the opening direction of the frame 1, so that the receiving groove is communicated with the opening of the frame 1, which facilitates the placement and removal of the battery pack 210.

[0080] The two main beams 211 are respectively fixedly connected to the two ends of the frame 1 in the transverse direction. Specifically, the two main beams 211 are arranged one by one corresponding to the two column 11 groups, and each main beam 211 is fixedly connected to the inner side of the column 11 of the corresponding column 11 group in the transverse direction.

[0081] In the embodiment, the main beams 211 include a bottom plate 2111 and side plates 2112. Specifically, the bottom plate 2111 extends in the horizontal direction and serves as a support for the battery pack 210. The side plates 2112 are erected on the top of the lateral outer sides of the bottom plate 2111 and serve to be connected and fixed with the frame 1.

[0082] In the embodiment, the main beams 211 include bent plates 2113. The bent plates 2113 are connected between the bottom plate 2111 and the side plates 2112 and located on the side away from the opening of the frame 1, and serve to abut against the battery pack 210 to limit the battery pack 210 in the longitudinal direction.

[0083] A plurality of support beams 212 are connected on the two main beams 211 in the longitudinal direction. Specifically, the support beams 212 extend in the lateral direction. The lateral ends of the support beams 212 are respectively fixedly connected with the bottom of the bottom plate 2111 of the two main beams 211 one by one.

[0084] In the embodiment, the support beams 212 are flat.

[0085] In the embodiment, at least part of the top surface of the support beams 212 in the length direction can be flush with the top surface of the bottom plate 2111, so as to facilitate the placement of the battery pack 210 and improve the stability of the support of the battery pack 210.

[0086] In the embodiment, the thickness of the lateral ends of the support beams 212 is less than the thickness of the middle part, so that after the lateral ends of the support beams 212 are fixedly connected with the bottom of the bottom plate 2111, the middle part of the support beams 212 can protrude upward, and the top surface of the support beams 212 can be flush with the top surface of the bottom plate 2111, so as to cooperate with the bottom plate 2111 to support the battery pack 210.

[0087] In the embodiment, the support frame 21 further includes two fixed plates 2114 spaced apart in the lateral direction, and the fixed plates 2114 are located at the bottom of the end of the support frame 21 facing the opening of the frame 1. The fixed plates 2114 extend in the vertical direction. Specifically, the two fixed plates 2114 are arranged one by one with the two main beams 211. Each fixed plate 2114 is arranged at the bottom of the bottom plate 2111 of the corresponding main beam 211 and located at the end of the bottom plate 2111 facing the opening of the frame 1.

[0088] In the embodiment, the two first limiting members 22 are used to be connected one by one with the lateral sides of the battery pack 210.

[0089] Figure 6 For Figure 5 The enlarged structure schematic view at A.

[0090] Referring to Figure 4 , Figure 5 and Figure 6 , each first limiting member 22 has an inclined surface.

[0091] In the embodiment, each first limiting piece 22 comprises a first limiting plate 221 and an abutting plate 222.

[0092] The first limiting plate 221 is provided with at least one first limiting hole 2211, which is in one-to-one correspondence with the perforations 2102 on the bottom edge 2101 of the battery pack 210, and the two are matched to pass through the mounting piece 3, thereby realizing the connection between the battery pack 210 and the first limiting plate 221.

[0093] The abutting plate 222 is arranged on the top of the first limiting plate 221 and is used to abut the upper outer periphery of the battery pack 210. Specifically, the abutting plate 222 is connected to the longitudinal end of the first limiting plate 221.

[0094] In the embodiment, the abutting plate 222 is arranged obliquely relative to the first limiting plate 221. Specifically, the abutting plate 222 is arranged obliquely upward along the longitudinal direction and is located directly above the first limiting plate 221. At this time, the top surface of the abutting plate 222 constitutes an inclined surface.

[0095] In the embodiment, the first limiting piece 22 can further comprise a support plate 223 and an extension plate 224, and the first limiting plate 221, the abutting plate 222, the extension plate 224, and the support plate 223 are sequentially connected end to end to form a structure with a trapezoidal cross section. The longitudinal dimension of the first limiting plate 221 is greater than the longitudinal dimension of the extension plate 224, so that the first limiting piece 22 has a larger contact area with the bottom edge 2101 of the battery pack 210 through the first limiting plate 221, and at the same time, the first limiting piece 22 has better stability. Specifically, the cross section of the first limiting piece 22 is a right trapezoid, that is, the support plate 223 is erected between the first limiting plate 221 and the extension plate 224.

[0096] In other embodiments, the extension plate 224 can be omitted, that is, the first limiting piece 22 comprises the first limiting plate 221, the abutting plate 222, and the support plate 223. At this time, the first limiting plate 221, the abutting plate 222, and the support plate 223 are sequentially connected end to end to form a structure with a triangular cross section.

[0097] In the embodiment, the two pressure connecting pieces 24 are arranged on the support frame 21 in a transverse direction, and the two pressure connecting pieces 24 are used to abut the two sides of the battery pack 210 in the transverse direction to transversely limit the battery pack 210.

[0098] Furthermore, each pressure connecting piece 24 has a vertical spacing with the support frame 21, and each pressure connecting piece 24 is pressure-connected with a first limiting piece 22 to press the battery pack 210 on the support frame 21, thereby exerting a pressure on the battery pack 210 in the vertical direction to limit the battery pack 210 in the vertical direction.

[0099] Two pressing members 24 are arranged on the inner side wall of the support frame 21 away from the opening of the frame 1. Specifically, the two pressing members 24 are fixedly connected with the two bent plates 2113 one by one, and each pressing member 24 is located at the upper end of the corresponding bent plate 2113, so that the pressing member 24 and the bottom plate 2111 have a vertical spacing.

[0109] In the embodiment, the shape of the reinforcing plate 232 can be triangular, trapezoidal, etc. Specifically, the reinforcing plate 232 is a right triangle or a right trapezoid.

[0110] In the embodiment, the second limiting member 23 further comprises a mounting plate 233 connected between the two reinforcing plates 232 and the second limiting plate 231. The mounting plate 233 extends along the vertical direction.

[0111] In the embodiment, the mounting assembly 2 further comprises two connecting members 25 arranged on the supporting frame 21 in the transverse direction. Each connecting member 25 is used for connecting and fixing the second limiting member 23 and the supporting frame 21, thereby reinforcing the connection strength of the battery pack 210 and the frame 1 and improving the mounting stability of the battery pack 210.

The reinforcing plate 252 is used to press the top of the second limiting member 23 to press the battery pack 210 tightly on the support frame 21. That is, in actual application, after the connecting plate 251 is connected and fixed with the mounting plate 233 and the fixed plate 2114 through the fixing member 4, the reinforcing plate 252 can be pressed on the top of the second limiting member 23. In this way, the second limiting member 23 and the battery pack 210 can be pressed tightly on the support frame 21, thereby enhancing the vertical limiting and fixation of the battery pack 210.

[0116] Referring to Figure 4 and Figure 5 , the mounting assembly 2 further includes a plurality of positioning blocks 26 distributed on the bottom wall of the support frame 21 in a circumferential direction.

[0117] In this embodiment, the mounting assembly 2 further comprises at least two positioning columns 27, which are arranged on the inner side wall of the support frame 21 away from the opening end of the frame 1 in a transverse direction, and extend in a longitudinal direction. At this time, the battery pack 210 is provided with at least two positioning holes 2103, which are arranged one-to-one corresponding to the arrangement positions of the at least two positioning columns 27, so that the positioning columns 27 can be inserted into the positioning holes 2103 on the battery pack 210 to realize the positioning of the battery pack 210 in the transverse direction. Specifically, the longitudinal inner side of each bent plate 2113 is provided with at least one positioning column 27.

[0118] With reference to Figure 1 and Figure 2 , the battery cluster mounting rack 100 further comprises a supporting frame 5 arranged in the frame 1 and below all the support frames 21, for supporting and fixing the high-voltage box 220.

[0119] An exemplary mounting and fixing step of the battery pack 210 is as follows:

[0120] S1, each first limiting piece 22 is connected and fixed to the bottom edge 2101 of the battery pack 210 through the mounting piece 3, and each second limiting piece 23 is connected and fixed to the bottom edge 2101 of the battery pack 210 through the locking piece 6. The inclined surface of the first limiting piece 22 is inclined from bottom to top towards the direction of the second limiting piece 23.

[0121] S2, one end of the battery pack 210 connected with the first limiting piece 22 is first inserted into the frame 1 through the opening of the frame 1, and the battery pack 210 is slid along the support surface of one support frame 21 towards the direction away from the opening of the frame 1 until the battery pack 210 is completely placed on the support frame 21. In this process, the positioning blocks 26 of the two positioning groups can guide and limit the bottom edge 2101 of the battery pack 210, and since the abutting plate 222 of the first limiting piece 22 is inclined from bottom to top towards the direction of the second limiting piece 23, the abutting plate 222 of the first limiting piece 22 can cooperate with the guide surface on the upper abutting plate 241 of the pressing piece 24, so that the guide surface plays a guiding role for the movement of the inclined surface and prevents the battery pack 210 from deviating. Until the positioning column 27 provided on the bent plate 2113 is completely inserted into the positioning hole 2103 on the battery pack 210, and the bent plate 2113 abuts against the bottom edge 2101 of the battery pack 210, and the upper abutting plate 241 of the pressing piece 24 is in pressing cooperation with the first limiting piece 22, that is, the battery pack 210 is completely placed on the support frame 21.

[0122] S3, the connecting plate 251 of the connecting piece 25 is attached to the mounting plate 233 of the second limiting piece 23 and the fixed plate 2114 of the main beam 211, and the connecting plate 251 is connected and fixed with the mounting plate 233 and the fixed plate 2114 through the fixing piece 4, that is, the installation of the battery pack 210 is completed.

[0123] It should be particularly pointed out that the above steps have no sequence and can be adjusted according to actual conditions.

[0124] From the above technical solution, the utility model has at least the following advantages and positive effects:

[0125] In the embodiment, a containing groove is formed on the support frame to preliminarily contain and limit the battery pack. Further, two pressure connecting pieces are arranged on the support frame along the transverse direction at intervals, and the two pressure connecting pieces can abut against the transverse two sides of the battery pack to further abut against and limit the battery pack. Meanwhile, each pressure connecting piece has a vertical interval with the bottom wall of the support frame, and the interval can be used for the bottom edge of the battery pack to pass through. Then, each pressure connecting piece can correspond to and be press-fitted with the first limiting piece connected to the transverse side of the battery pack, and a downward pressure is applied to the battery pack. In this way, the battery pack can be pressed tightly on the support frame along the vertical direction, and the limiting and fixing of the battery pack in the vertical direction are realized. In this way, displacement of the battery pack during movement can be avoided, and the safety and stability of the battery pack can be more effectively ensured.

[0126] Further, each first limiting piece has an inclined surface, and a guide surface in an inclined shape is arranged on each pressure connecting piece correspondingly. The guide surface and the inclined surface are movably fitted, so that when the battery pack moves along the bottom wall of the support frame to the position where the first limiting piece is below the pressure connecting piece and continues to move, the guide surface can guide the movement of the inclined surface. In this way, the battery pack can be prevented from deviating from the direction, and the smoothness of the movement of the first limiting piece relative to the pressure connecting piece can be improved.
