[0002] A battery pack mounting bracket is a component used to support and secure a battery pack. For example, a battery pack mounting bracket can be used to fix the battery pack to energy storage devices, electrical appliances, and other equipment.

[0003] In related technologies, a support plate is installed on the battery pack mounting bracket to support and fix the battery pack. A buffer layer is also provided on the support plate to cushion the battery pack. The number of buffer layers is generally multiple, and each buffer layer is fixed together by adhesive, and finally glued to the support plate, thus installing multiple buffer layers onto the support plate.

[0004] However, this installation method, which requires bonding between adjacent buffer layers and between the buffer layer and the support plate, is quite complex, resulting in low installation efficiency and overall low production efficiency. Utility Model Content

[0038] The battery pack mounting bracket and energy storage device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, a battery pack mounting bracket according to some embodiments of this application includes a frame 10, a support member 20, and a buffer member 30. The frame 10 has a receiving space 11, and the support member 20 is disposed in the receiving space 11 to divide the receiving space 11 into at least one receiving cavity 12 for receiving a battery pack 60. The support member 20 has a support surface on the side facing the receiving cavity 12, and the support surface is used to support the battery pack 60. The support member 20 is provided with a mounting hole 21 penetrating the support surface. The buffer member 30 is disposed on the support surface, and the buffer member 30 has a snap-fit ​​portion 31 on the side facing the support surface, and the snap-fit ​​portion 31 snaps into the mounting hole 21.

[0040] In this embodiment, the support member 20 and the buffer member 30 are connected and installed through the snap-fit ​​part 31, eliminating the need for adhesive bonding between adjacent components, thus simplifying the installation operation and improving installation efficiency.

[0041] Among them, such as Figure 1 As shown, the frame 10 forms an integral structure of the battery pack mounting bracket, which can be welded from profiles (such as channel steel, square steel pipe, etc.). The frame 10 has an internal accommodating space 11, which can be used to accommodate the battery pack 60.

[0042] like Figure 1 As shown, the support member 20 is disposed in the receiving space 11, which can divide the receiving space 11 into at least one receiving cavity 12. The battery pack 60 is placed in the receiving cavity 12, and the support member 20 can provide support. Of course, the number of receiving cavities 12 is related to the number of support members 20 disposed in the receiving space 11. The number of receiving cavities 12 and the number of support members 20 can be flexibly set according to the actual situation. This application embodiment does not limit this.

[0043] For example, the support member 20 is a steel structure that can be welded or bolted to the frame 10. Of course, the specific type and installation method of the support member 20 can be flexibly set according to the actual situation, and this application embodiment does not limit this.

[0044] like Figure 3 As shown, the support member 20 has a support surface on the side facing the receiving cavity 12. The support surface is used to support and carry the battery pack 60. The support member 20 is provided with a mounting hole 21 that penetrates the support surface. The mounting hole 21 can be matched with other structures to realize installation.

[0045] like Figure 2 and Figure 3 As shown, the buffer 30 is disposed on the support surface, and the buffer 30 has a snap-fit ​​part 31 on the side facing the support surface. The snap-fit ​​part 31 can snap-fit ​​with the mounting hole 21, thereby realizing the snap-fit ​​installation of the buffer 30 and the support 20 without the need for adhesive bonding.

[0046] Optionally, such as Figure 3 and Figure 4 As shown, the snap-fit ​​part 31 includes a connecting section 32 and a snap-fit ​​section 33. The connecting section 32 is located on the side of the buffer member 30 facing the support surface, and the snap-fit ​​section 33 is located at the end of the connecting section 32 away from the buffer member 30. The snap-fit ​​section 33 protrudes circumferentially from the connecting section 32. The connecting section 32 passes through the mounting hole 21, and the snap-fit ​​section 33 snaps into the side of the support member 20 away from the support surface.

[0047] In this embodiment, the connecting segment 32 can pass through the mounting hole 21, and the snap-fit ​​segment 33 can snap-fit ​​with the side of the support member 20 away from the support surface, thereby forming a good snap-fit ​​structure that can withstand the frictional force on the buffer member 30 when the battery pack 60 is installed, thus preventing the buffer member 30 from separating from the support member 20.

[0048] Specifically, such as Figure 3 As shown, the connecting section 32 is inserted into the mounting hole 21, and the snap-fit ​​section 33 snaps into the side of the support member 20 away from the support surface, that is, the snap-fit ​​section 33 snaps into the edge of the mounting hole 21.

[0049] Optionally, such as Figure 4As shown, the connecting section 32 includes multiple sub-connecting sections 321, which are arranged at intervals along the circumference of the mounting hole 21. The multiple sub-connecting sections 321 enclose a gap space 322, and each sub-connecting section 321 has a snap-fit ​​section 33 on the side opposite to the gap space 322.

[0050] In this embodiment, multiple sub-connecting segments 321 enclose a gap space 322, so that any two sub-connecting segments 321 do not contact each other. When the sub-connecting segments 321 are subjected to an external force toward the gap space 322, they can deform to a certain extent and bend toward the gap space 322, making it easy for the sub-connecting segments 321 to be inserted into the mounting hole 21. After the external force disappears, the deformation of the sub-connecting segments 321 disappears, and the snap-fit ​​segment 33 snaps into the mounting hole 21.

[0051] Specifically, such as Figure 4 As shown, multiple sub-connecting segments 321 are arranged at circumferential intervals along the mounting hole 21, and the multiple sub-connecting segments 321 enclose a gap space 322. The sub-connecting segments 321 can be bent toward the gap space 322. For example, the number of sub-connecting segments 321 is four, and the gap space 322 is formed between the four sub-connecting segments 321. The gap space 322 is in the shape of a cross groove, which facilitates the bending of the sub-connecting segments 321 toward the gap space 322.

[0052] Optionally, such as Figure 6 As shown, the snap-fit ​​section 33 is provided with a guide slope 331. The guide slope 331 is located on one side of the snap-fit ​​section 33 back ion connection section 321. The guide slope 331 extends obliquely from the side of the snap-fit ​​section 33 near the sub-connection section 321 to the side of the snap-fit ​​section 33 away from the sub-connection section 321. The end of the guide slope 331 away from the sub-connection section 321 is closer to the buffer member 30 than the end of the guide slope 331 near the sub-connection section 321.

[0053] In this embodiment of the application, when the sub-connecting segment 321 is inserted into the mounting hole 21, the guide slope 331 can abut against the edge of the mounting hole 21, thereby causing the sub-connecting segment 321 to bend toward the gap space 322, that is, to bend toward the center of the mounting hole 21, so that the sub-connecting segment 321 can be inserted into the mounting hole 21, which is convenient for insertion into the mounting hole 21.

[0054] Specifically, such as Figure 6 As shown, the snap-fit ​​section 33 is provided with a guide slope 331, which is used to abut against the edge of the mounting hole 21, causing the sub-connecting section 321 to bend and be inserted into the mounting hole 21.

[0055] Optionally, such as Figure 3As shown, the buffer member 30 includes a first buffer layer 40 and a second buffer layer 50 stacked together. The second buffer layer 50 is disposed on the support surface, and the first buffer layer 40 is disposed on the side of the second buffer layer 50 away from the support member 20. The snap-fit ​​part 31 is disposed on the side of the first buffer layer 40 facing the second buffer layer 50. The second buffer layer 50 is provided with a through hole 51 extending along the stacking direction of the first buffer layer 40 and the second buffer layer 50. The snap-fit ​​part 31 passes through the through hole 51 and snaps into the mounting hole 21.

[0056] In this embodiment of the application, by providing a snap-fit ​​portion 31 in the first buffer layer 40 and a through hole 51 in the second buffer layer 50, the second buffer layer 50 can be firmly snapped between the first buffer layer 40 and the support member 20, thereby realizing the snap-fit ​​installation of multiple buffer layers.

[0057] Specifically, such as Figure 3 As shown, the buffer 30 is a multi-layer buffer layer, which is stacked with the support 20. The first buffer layer 40 is away from the support 20. The snap-fit ​​part 31 is provided on the first buffer layer 40. The second buffer layer 50 is provided with a through hole 51. The snap-fit ​​part 31 passes through the through hole 51 and snaps into the mounting hole 21.

[0058] It should be noted that the first buffer layer 40 is a single-layer structure, and the second buffer layer 50 can also be a multi-layer structure. All of these multi-layer structures are provided with through holes 51, and the snap-fit ​​part 31 passes through the through holes 51, thereby realizing the snap-fit ​​installation of the multi-layer structure.

[0059] For example, the support member 20 is the main component that bears the weight of the battery pack 60 and can be a steel structure. The buffer member 30 is the component that provides cushioning and can include multiple buffer layers. The first buffer layer 40 is the structure that directly contacts the battery pack 60 and can be made of PC material (polycarbonate). PC material has good insulation properties and can achieve insulation between the battery pack 60 and the support member 20. The second buffer layer 50 can include a rubber pad layer, which can provide good cushioning. Of course, the second buffer layer 50 can also include other material layers to increase the cushioning effect. The specific composition of the second buffer layer 50 can be flexibly set according to the actual situation, and this embodiment does not limit it.

[0060] Optionally, such as Figure 1 and Figure 3 As shown, the frame 10 has a first direction X, and the support member 20 is provided with a plurality of mounting holes 21 spaced apart along the first direction X, and each mounting hole 21 is fitted with a locking part 31.

[0061] In this embodiment, by providing multiple mounting holes 21 on the support member 20 and correspondingly providing multiple snap-fit ​​parts 31 on the buffer member 30, multiple snap-fit ​​positions are achieved, making the snap-fit ​​between the support member 20 and the buffer member 30 more secure and improving the snap-fit ​​stability between the two.

[0062] Specifically, such as Figure 1 and Figure 3 As shown, the support member 20 is provided with a plurality of mounting holes 21 spaced apart along the first direction X. Each mounting hole 21 is fitted with a locking part 31 to achieve multi-position locking. The first direction X is the direction of movement of the battery pack 60 into the receiving cavity 12, that is, the battery pack 60 is installed into the receiving cavity 12 along the first direction X.

[0063] Optionally, such as Figure 1 and Figure 3 As shown, the frame 10 has a second direction Y, which is perpendicular to the first direction X. The support member 20 includes two support plates 22 and a connecting plate 23 connecting the two support plates 22. The two support plates 22 are spaced apart along the second direction Y in the accommodating space 11. The connecting plate 23 and the two support plates 22 are integrally formed.

[0064] In this embodiment, the connecting plate 23 and the two support plates 22 are integrally formed, which allows the three components to be manufactured in one piece, reducing subsequent assembly processes and improving the strength of the connection between the connecting plate 23 and the two support plates 22.

[0065] Specifically, such as Figure 1 and Figure 3 As shown, two support plates 22 are spaced apart along the second direction Y in the accommodating space 11, providing support from two positions of the battery pack 60, resulting in a more rational structure. The connecting plate 23 and the two support plates 22 are integrally formed, creating a single structure that requires no further assembly.

[0066] It should be noted that the dimensions of the support plate 22 and the connecting plate 23 can be adjusted according to the dimensions of the battery pack 60 to be supported, so as to adapt to battery packs 60 of different sizes.

[0067] In addition, both the support plate 22 and the connecting plate 23 can be formed with folded edges, so that their cross-sections are L-shaped, which improves the structural stability of the support plate 22 and the connecting plate 23 and reduces the possibility of bending when supporting the battery pack 60.

[0068] Of course, such as Figure 1 As shown, the frame 10 also has a third direction Z, which is perpendicular to the first direction X and the second direction Y. By reasonably arranging the support members 20, the receiving cavity 12 can be arranged along the second direction Y and the third direction Z, and can accommodate multiple battery packs 60.

[0069] It should be noted that the first direction X, the second direction Y, and the third direction Z are mutually perpendicular. Specifically, this can be "perpendicular" in the strict sense, for example, the angle between the first direction X and the second direction Y is 90°; or it can be "approximately perpendicular," specifically meaning that the angle between any two of the first direction X, the second direction Y, and the third direction Z includes a certain error. Considering the measurement and the error associated with the measurement of a specific quantity (i.e., the limitations of the measurement system), this error is within the acceptable deviation range for a specific value as determined by a person skilled in the art. For example, the angle between the first direction X and the second direction Y is 90° ± 5°.

[0070] Optionally, such as Figure 7 , Figure 8 and Figure 9 As shown, this application embodiment also provides an energy storage device, including a battery pack 60 and a battery pack mounting frame of any of the above embodiments. The frame 10 has a first direction X, and the receiving cavity 12 is provided with an opening 121 on one side along the first direction X. The battery pack 60 includes a battery pack body 61 and a first limiting part 62. The battery pack body 61 is disposed in the receiving cavity 12, and the first limiting part 62 is disposed on the side of the battery pack body 61 away from the opening 121. The support member 20 is provided with a second limiting part 24, which is disposed on the side of the support member 20 away from the opening 121. The second limiting part 24 cooperates with the first limiting part 62 to limit the movement.

[0071] In this embodiment, after the battery pack 60 is installed into the receiving cavity 12, it can be limited by the second limiting part 24 and the first limiting part 62, reducing the possibility of the battery pack 60 moving when it is not fixed.

[0072] Specifically, the battery pack 60 is placed into the receiving cavity 12 along the first direction X. When the battery pack 60 is placed in, the first limiting part 62 gradually approaches the second limiting part 24. After the battery pack 60 is placed in place, the second limiting part 24 cooperates with the first limiting part 62 to limit it.

[0073] It should be noted that the battery pack body 61 has a fixing structure on the side facing the cavity 121 that cooperates with the support member 20. For example, both the support member 20 and the battery pack body 61 are provided with through holes, and the two are fixed by bolts, thereby fixing the battery pack 60. The cooperation between the second limiting part 24 and the first limiting part 62 can achieve good positioning even before the battery pack 60 is fixed.

[0074] Optionally, such as Figure 8As shown, the first limiting part 62 includes a mounting plate 63 and an elastic limiting plate 64. The mounting plate 63 is located on the side of the battery pack body 61 away from the cavity 121. The elastic limiting plate 64 is located on the side of the mounting plate 63 facing the second limiting part 24. The second limiting part 24 is provided with a limiting hole 25. The elastic limiting plate 64 is at least partially inserted into the limiting hole 25.

[0075] In this embodiment, the battery pack 60 and the support member 20 are limited by the snap-fit ​​between the elastic limiting plate 64 and the limiting hole 25. The elastic limiting plate 64 is snapped into the limiting hole 25, and the limiting is achieved by the snap-fit. The structure is simple and the snap-fit ​​can be automatically achieved when the battery pack 60 is put in, without the need for special operation of the snap-fit ​​process.

[0076] Specifically, such as Figure 8 As shown, the mounting plate 63 is connected to the battery pack body 61, and the elastic limiting plate 64 is connected to the mounting plate 63. The elastic limiting plate 64 is a component that can undergo elastic deformation and is engaged with the limiting hole 25.

[0077] Optionally, such as Figure 8 As shown, the elastic limiting plate 64 includes a first end 641, a second end 642, and a protruding connecting section 643 connecting the first end 641 and the second end 642. The first end 641 is bent and connected to the end of the mounting plate 63 near the cavity 121. The second end 642 extends beyond the end of the mounting plate 63 away from the cavity 121. An adjustment gap is formed between the second end 642 and the end of the mounting plate 63 away from the cavity 121 so that the protruding connecting section 643 can approach or move away from the mounting plate 63. The protruding connecting section 643 is engaged in the limiting hole 25.

[0078] In this embodiment, the first end 641 is bent, the protruding connecting section 643 is bent relative to the mounting plate 63, and the second end 642 extends beyond the end of the mounting plate 63 away from the cavity 121. When the battery pack 60 is inserted, the protruding connecting section 643 contacts the second limiting part 24 and can be bent to a certain extent. The end of the mounting plate 63 away from the cavity 121 will not block the movement of the second end 642, so that the protruding connecting section 643 can approach the mounting plate 63. As the battery pack 60 continues to be inserted, the protruding connecting section 643 is inserted into the limiting hole 25.

[0079] Specifically, such as Figure 8 As shown, the first end 641 of the elastic limiting plate 64 is bent and connected to the support plate 22. The protruding connecting section 643 connects the first end 641 and the second end 642. The second end 642 extends beyond the end of the mounting plate 63 away from the cavity 121. When the protruding connecting section 643 approaches the mounting plate 63, the second end 642 will not be blocked by the mounting plate 63.

[0080] For example, the elastic limiting plate 64 can be a steel plate with a thickness of 1 mm, which has good elasticity after bending, so that the deformation of the elastic limiting plate 64 can be recovered within a certain range, realizing repeated use. Of course, the material and thickness of the elastic limiting plate 64 can be flexibly set according to the actual situation, and this application embodiment does not limit it in this way.

[0081] It should be noted that an avoidance notch can also be provided at the end of the mounting plate 63 away from the cavity 121. The second end 642 of the elastic limiting plate 64 can be located at this avoidance notch, which will not obstruct the movement of the second end 642. At the same time, the distance between the first end 641 and the second end 642 can be appropriately reduced, thereby reducing the amount of material used in the production of the elastic limiting plate 64.
