[0001] Cross - reference to Related Applications This disclosure is provided based on Chinese Patent Application No. 202321025075.6 filed on April 28, 2023, which is incorporated herein by reference in its entirety, and claims priority to this Chinese patent application.

[0002] This disclosure relates to the field of battery technology, and more particularly, to battery pack housings, battery packs, and electrical devices.

Background Art

[0003] In related technologies, in a battery pack, generally a baffle is disposed between a battery and the side frame of the tray of the battery pack housing, and a power distribution space for attaching electrical elements is formed between the baffle and the side frame. However, when the battery is fixed by using a foaming adhesive, the expansion force generated in the foaming process of the foaming adhesive may break the baffle, and thus, there is a risk that the foaming adhesive and the baffle may enter the power distribution space.

Summary of the Invention

[0004] This disclosure aims to solve at least to a certain extent one of the technical problems in the related technologies.

[0005] Therefore, an object of this disclosure is to provide a battery pack housing.

[0006] Another object of this disclosure is to provide a battery pack.

[0007] Yet another object of this disclosure is to provide an electrical device.

[0008] To achieve the aforementioned objectives, one embodiment of a first aspect of the present disclosure provides a battery pack housing comprising a tray having a housing cavity formed therein, and a support assembly disposed within the housing cavity, the support assembly comprising a partition member and a support member, wherein the partition member divides the housing cavity into a battery mounting space and a power distribution space, and the support member is located within the power distribution space and is supported between the partition member and the side frame of the tray.

[0009] According to this embodiment of the present disclosure, the battery pack housing is provided with a support assembly, the support assembly including a partition member and a support member.

The partition member is located between the battery and the support member and is subjected to compressive forces caused by expansion resulting from the curing of the foam adhesive, and the support member is supported between the partition member and the side frame of the tray. Thus, the compressive forces caused by expansion that the partition member receives can be distributed to the side frame of the tray through the support member, thereby enabling the partition member to effectively withstand the compressive forces caused by expansion from the foam adhesive, thereby preventing the partition member from entering the power distribution space formed between the partition member and the side frame.

[0011] According to the battery pack in this embodiment of the present disclosure, since the aforementioned battery pack housing is provided, the compressive force caused by expansion acting on the partition member can be distributed to the side frame of the tray through the support member, thereby enabling the partition member to effectively withstand the compressive force caused by expansion from the foam adhesive, thereby preventing the partition member from entering the power distribution space formed between the partition member and the side frame.

[0012] To achieve the aforementioned objectives, one embodiment of a third aspect of the present disclosure provides an electrical device including a battery pack in an embodiment of the second aspect.

[0013] According to the electrical device in this embodiment of the present disclosure, since the aforementioned battery pack is provided, the compressive force caused by expansion acting on the partition member can be distributed to the side frame of the tray through the support member, thereby enabling the partition member to effectively withstand the compressive force caused by expansion from the foam adhesive, and thereby preventing the partition member from entering the power distribution space formed between the partition member and the side frame.

[0016] The embodiments of this disclosure are described in detail below. Examples of embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements, or elements having the same or similar function, throughout the drawings. The embodiments described below with reference to the accompanying drawings are examples and are for illustrative purposes of this disclosure and should not be understood as limitations to this disclosure.

[0017] In the following, the battery pack housing 100, battery pack 200, and electrical device 300 according to embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0018] As shown in Figures 1 to 10, a battery pack housing 100 according to one embodiment of a first aspect of the present disclosure includes a tray 2 and a support assembly 3. A housing cavity 21 is formed in the tray 2, and the support assembly 3 is disposed within the housing cavity 21. The support assembly 3 includes a partition member 31 and a support member 32, the partition member 31 dividing the housing cavity 21 into a battery mounting space 23 and a power distribution space 24, and the support member 32 is located within the power distribution space 24 and is supported between the partition member 31 and the side frame 22 of the tray 2.

[0019] Specifically, as shown in FIG. 2, in the process of assembling the battery pack housing 100, the battery 1 and the support assembly 3 are mounted in the accommodation cavity 21 of the tray 2. The support assembly 3 includes a partition member 31. The partition member 31 can be a plate-like structure, but is not limited thereto. The partition member 31 is arranged parallel to the side frame 22 and separates the battery 1 from the side frame 22. As shown in FIG. 1, the accommodation cavity 21 is partitioned by the partition member 31 into a battery mounting space 23 and a power distribution space 24. The battery mounting space 23 is configured to mount the battery located within the power distribution space. The power distribution space 24 is configured to mount various electrical components such as the power distribution box 4, the temperature collector, and the signal sensor. Thereby, separation between the battery 1 and various electrical components by the partition member 31 becomes possible. After the battery 1 and the support assembly 3 are mounted, continuing to refer to FIG. 2, the foaming adhesive 7 is injected into the battery mounting space 23, and by using the foaming adhesive 7, the battery 1 is cured to fix the battery 1 to the tray 2. The foaming adhesive 7 expands during the curing process, and the expansion force generated by the expansion is transmitted to the partition member. The support assembly 3 further includes a support member 32. The support member 32 is located within the power distribution space 24 and is supported between the partition member 31 and the side frame 22 of the tray 2. Therefore, the compressive force caused by the expansion received by the partition member is transmitted to the side frame 22 through the support member 32, which corresponds to sharing a part of the compressive force caused by the expansion. Optionally, the support member 32 is vertically arranged between the partition member 31 and the side frame 22 of the tray 2. With this arrangement, dispersion of the transmitted force can be avoided, a good route for force transmission is ensured, the transmission effect of the compressive force caused by the expansion is improved, and as a result, more of the compressive force caused by the expansion is transmitted to the side frame 22. Thus, the partition member 31 can effectively withstand the compressive force caused by the expansion from the foaming adhesive 7, thereby preventing the compressive force caused by the expansion from breaking through the partition member 31 and entering the power distribution space 24 formed between the partition member 31 and the side frame 22.

[0020] According to the battery pack housing 100 in this embodiment of the present disclosure, a support assembly 3 is provided in the battery pack housing 100. The support assembly 3 includes a partition member 31 and a support member 32. The partition member 31 partitions the accommodation cavity 21 into a battery mounting space 23 and a power distribution space 24. The partition member 31 is located between the battery 1 and the support member 32 and receives the compressive force caused by the expansion generated by the curing of the foam adhesive 7. The support member 32 is supported between the partition member 31 and the side frame 22 of the tray 2. Therefore, the compressive force caused by the expansion received by the partition member 31 can be dispersed to the side frame 22 of the tray 2 through the support member 32. As a result, the partition member 31 can effectively withstand the compressive force caused by the expansion from the foam adhesive 7, thereby preventing the partition member 31 from invading into the power distribution space 24 formed between the partition member 31 and the side frame 22.

[0021] It should be noted that the support assembly 3 is formed by the partition member 31 and the support member 32, and the actual size of the support member 32 may be adjusted based on the size of the tray 2. When the tray 2 is relatively large, the size of the support member 32 may be increased, and when the tray 2 is relatively small, the size of the support member 32 may be reduced. By attaching a support member 32 with a suitable size to the partition member 31, a support assembly 3 that meets the current requirements of the tray 2 can be formed, thereby improving the applicability of the support assembly 3.

[0022] In some embodiments of the present disclosure, as shown in FIGS. 3 and 5, a first assembling portion 311 is provided on the partition member 31, a second assembling portion 321 is provided on the support member 32, and the first assembling portion 311 and the second assembling portion 321 are assembled by fitting to fix the partition member 31 to the support member 32.

[0023] Specifically, the support assembly 3 can be an integrally formed member, or it can be formed by a detachable partition member 31 and a support member 32. This disclosure will be explained using a detachable partition member 31 and a support member 32 as an example, in which the partition member 31 is provided with a first assembly 311 and the support member 32 is provided with a second assembly 321, and the first assembly 311 and the second assembly 321 face each other. For example, the second assembly 321 may be constructed as a protruding structure, and the formed protruding structure protrudes toward the partition member 31. The first assembly 311 may be constructed as a recessed structure that fits into the second assembly 321. The first assembly 311 is constructed as a recessed structure that is recessed from the surface of the partition member 31 toward the interior of the partition member 31. In the process of assembling the support assembly 3, the second assembly portion 321 of the support member 32 is appropriately attached to the first assembly portion 311 of the partition member 31, thereby achieving a fixed attachment between the support member 32 and the partition member 31. This arrangement facilitates the fixed assembly of the support member 32 and the partition member 31, improving assembly efficiency.

[0024] In some embodiments of the present disclosure, the first assembly portion 311 is one of an assembly groove and a mounting boss, and the second assembly portion 321 is the other of the assembly groove and mounting boss.

[0025] Specifically, if the first assembly part 311 is either an assembly groove or a mounting boss, then the second assembly part 321 is the other of the assembly groove and the mounting boss. For example, if the first assembly part 311 is an assembly groove, then the second assembly part 321 is a mounting boss, and if the first assembly part 311 is a mounting boss, then the second assembly part 321 is an assembly groove. This disclosure will be explained by using an example in which the first assembly part 311 is an assembly groove and the second assembly part 321 is a mounting boss. The assembly groove may be a recess, but is not limited to this, and the mounting boss is a boss corresponding to the recess. Furthermore, the assembly groove and the mounting boss may each be provided with corresponding assembly bevels. With this arrangement, when the assembly groove and the mounting boss are assembled by fitting, assembly is assisted by using the assembly bevels, which reduces the difficulty of assembly and leads to further improvement in assembly efficiency.

[0026] In some embodiments of the present disclosure, as shown in Figure 5, the support member 32 includes a plurality of support sub-members 322, which are spaced apart in the longitudinal direction of the partition member 31.

[0027] Specifically, the support member 32 includes a plurality of support sub-members 322. The number of support sub-members 322 is determined according to specific needs. For example, the number of support sub-members 322 may be two, three, four, or five, and this is not particularly limited herein. The plurality of support sub-members 322 are arranged continuously in the longitudinal direction of the partition member 31, i.e., continuously in a first direction X. Each support sub-member 322 is fixedly assembled to the partition member 31 and is perpendicular to the partition member 31. For example, as shown in Figure 5, the support member 32 includes five support sub-members 322. Each support sub-member 322 is provided with a mounting boss, and the mounting boss of the support sub-member 322 and the assembly groove of the partition member 31 are assembled by fitting, so that the support sub-member 322 is attached to the partition member 31. Furthermore, each support sub-member 322 is supported between the partition member 31 and the side frame 22 of the tray 2. This arrangement allows the compressive force caused by the expansion of the foam adhesive 7 acting on the partition member 31 to be transmitted perpendicularly to the side frame 22 through the multiple support sub-members 322, which further enhances the transmission effect of the compression force caused by the expansion, thereby enabling the partition member 31 to withstand the compression force caused by the expansion of the foam adhesive 7 even more effectively.

[0028] In some embodiments of the present disclosure, as shown in Figures 1, 2, and 6 to 8, the battery pack housing 100 further includes a mounting bracket 5. The mounting bracket 5 is installed within the battery mounting space 23 and is adapted to mount the battery 1, with the partition member 31 being movably inserted into the mounting bracket 5.

[0029] Specifically, the battery pack housing 100 further includes a mounting bracket 5. The mounting bracket 5 is positioned within the battery mounting space 23 and at the bottom of the tray 2. The mounting bracket 5 is configured to mount the battery 1. After the battery 1 is mounted, the partition member 31 is movably inserted into the mounting bracket 5 in a third direction Z, thereby allowing the partition member 31 to be perpendicular to the mounting bracket 5. This arrangement allows the partition member 31 to be inserted directly into the mounting bracket 5, thereby improving assembly efficiency. Furthermore, after the battery 1, the mounting bracket 5, and the partition member 31 are assembled by fitting, foam adhesive 7 is injected into the battery mounting space 23, and the battery 1 and mounting bracket 5 are cured by using the foam adhesive 7, thereby allowing the battery 1 and mounting bracket 5 to be integrated and fixed to the tray 2, which increases the stability of the battery 1 during assembly.

[0030] In some embodiments of this disclosure, as shown in Figures 6 to 8, an exhaust channel 51 is formed on the mounting bracket 5, and an exhaust port 53 communicating with the exhaust channel 51 is provided on the mounting bracket 5, and the exhaust port 53 is adapted to correspond to the explosion-proof portion of the battery 1.

[0031] Furthermore, as shown in Figure 2, there are multiple batteries 1, and these batteries 1 are arranged in a continuous sequence. Additionally, as shown in Figure 2, all batteries 1 are fixedly mounted to the upper surface of the mounting bracket 5, achieving the effect of assembling the batteries 1 within the foam adhesive 7. That is, filling the batteries with the foam adhesive 7 increases the strength of the connection between two adjacent batteries 1, thereby improving the safety of the battery pack 200. Therefore, filling the batteries with the foam adhesive 7 contributes to increasing the stability of the batteries 1 within the adhesive-filled area, and as a result, the batteries 1 can be securely attached to the mounting bracket.

[0032] Furthermore, as shown in Figures 6 and 7, when the mounting bracket 5 is positioned in the direction shown in Figure 7, the discharge passage 51 is formed at the bottom of the mounting bracket 5 in the thickness direction (i.e., the third direction Z). In addition, in the thickness direction of the mounting bracket 5, as shown in Figure 6, the discharge port 53 is constructed as a through hole penetrating the mounting bracket 5, achieving the effect of the discharge port 53 communicating with the discharge passage 51.

[0033] Furthermore, when the batteries 1 are assembled to the mounting bracket 5, the explosion-proof portion of each battery 1 is positioned to correspond with the discharge port 53 in the thickness direction of the mounting bracket 5. As a result, even if the battery 1 experiences thermal runaway, the discharge port 53 can avoid the explosion-proof portion, ensuring that the explosion-proof portion opens properly. Gas released from inside the battery 1 flows into the discharge passage 51 through the discharge port 53, which allows the gas inside the battery 1 to be released rapidly. This reduces the pressure inside the battery 1 and further reduces the risk of the battery 1 exploding.

[0034] It should be noted that thermal runaway of battery 1 can lead to a pressure increase within battery 1. When the pressure inside battery 1 reaches a certain threshold, the gas inside battery 1 will break through the explosion-proof section, separating the explosion-proof section from battery 1. This allows the gas inside battery 1 to be rapidly released, thereby reducing the pressure inside battery 1, improving the safety of the battery pack and thus reducing the risk of battery 1 exploding.

[0035] Therefore, by aligning the discharge port 53 with the explosion-proof section of the battery 1, the discharge port 53 avoids the explosion-proof section in the thickness direction of the mounting bracket 5, thereby preventing the risk of the mounting bracket 5 blocking the explosion-proof section, ensuring that the explosion-proof section opens properly in the event of thermal runaway of the battery 1, thereby guaranteeing the safety of use of the battery 1, and further guaranteeing the safety of use of the battery pack.

[0036] It should be noted that the mounting bracket 5 and support assembly 3 may be made of high-strength heat-resistant insulating materials such as glass fiber composite material and thermal spray high heat-resistant metal coating. The aforementioned materials are relatively lightweight, have low manufacturing difficulty and cost, and are characterized by high compressive strength and good heat resistance, and can effectively prevent the intrusion of foam adhesive 7 into the power distribution space 24, thereby ensuring the integrity of the space. Furthermore, the aforementioned materials maintain their effectiveness under external high temperatures or internal failure of the battery 1 due to high temperatures, thereby ensuring the stability and smoothness of the discharge passage 51.

[0037] In some embodiments of this disclosure, as shown in Figures 3, 5, and 8, the partition member 31 is provided with a first insertion portion 312, and the mounting bracket 5 is provided with a second insertion portion 52, and the first insertion portion 312 and the second insertion portion 52 are in an insertion fit state, thereby assembling the partition member 31 to the mounting bracket 5.

[0038] Specifically, the partition member 31 is provided with a plurality of first insertion portions 312, which are arranged continuously in the longitudinal direction of the partition member 31. The mounting bracket 5 is provided with a plurality of second insertion portions 52, which correspond one-to-one with the plurality of first insertion portions 312. If the first insertion portion 312 is either an insertion sheet or an insertion groove, then the second insertion portion 52 is the other of the insertion sheet or insertion groove. For example, if the first insertion portion 312 is an insertion sheet, then the second insertion portion 52 is an insertion groove, and if the first insertion portion 312 is an insertion groove, then the second insertion portion 52 is an insertion sheet. The insertion sheet is inserted into the insertion groove, and the insertion sheet and insertion groove are in an intermediate fit or a tight fit state.

[0039] Furthermore, the first insertion portion 312 may be constructed as an insertion sheet, the formed insertion sheet extending away from the first adhesive baffle 3. The second insertion portion 52 may be constructed as an insertion groove fitted to the first insertion portion 312. As shown in Figure 8, the second insertion portion 52 is constructed as an insertion groove recessed from the upper surface of the mounting bracket 5 toward the interior of the mounting bracket 5, so that during insertion fitting between the first insertion portion 312 and the second insertion portion 52, the first insertion portion 312 is adapted to extend into the second insertion portion 52, thereby achieving the effect of insertion fitting between the first insertion portion 312 and the second insertion portion 52.

[0040] Therefore, during the assembly of the partition member 31 and the mounting bracket 5, the first insertion portion 312 may be inserted into the second insertion portion 52 in the third direction Z to achieve the fitting and mounting of the partition member 31 and the mounting bracket 5. The assembly process is simple and easy, which contributes to improving the assembly efficiency of the battery pack housing 100.

[0041] In some embodiments of the present invention, as shown in Figures 3 to 5, the support assembly 3 further includes a limiting member 33 which is inserted into a partition member 31, and the limiting member 33 and the partition member 31 together define a mounting passage 34 which is configured for mounting a pipeline.

[0042] Specifically, the support assembly 3 further includes a limiting member 33. The limiting member 33 and the mounting notch of the partition member 31 are assembled by insertion in a third direction Z to define a mounting passage 34. The mounting passage 34 is configured for mounting a pipeline, which includes, but is not limited to, a battery cooling pipeline. During pipeline installation, the pipeline is allowed to pass through the mounting notch of the partition member 31, and the limiting member 33 is inserted into the mounting notch of the partition member 31 in the third direction Z to secure the pipeline within the mounting passage 34. This arrangement enables the pipeline installation process in the second direction Y. If the height of the pipeline changes, it may be understood that the limiting member 33 may be flexibly adjusted in the third direction Z to obtain a mounting passage 34 that fits the pipeline. On the other hand, the mounting notch of the partition member 31 may be adjusted as appropriate based on a specific position of the pipeline. By adjusting the limiting member 33 to fit with the partition member 31, various mounting paths 34 can be obtained, thereby improving the applicability of the support assembly 3.

[0043] In some embodiments of this disclosure, as shown in Figure 4, the restricting member 33 is provided with a third insertion portion 331, and the partition member 31 is provided with a fourth insertion portion 313, and the third insertion portion 331 and the fourth insertion portion 313 are inserted and fitted together to assemble the restricting member 33 to the partition member 31.

[0044] Specifically, if the third insertion portion 331 is either an insertion sheet or an insertion groove, the fourth insertion portion 313 is the other of the insertion sheet and the insertion groove. For example, if the third insertion portion 331 is an insertion sheet, the fourth insertion portion 313 is an insertion groove, and if the third insertion portion 331 is an insertion groove, the fourth insertion portion 313 is an insertion sheet. The insertion sheet is inserted into the insertion groove, and the insertion sheet and insertion groove are in an intermediate fit or a tight fit. With this arrangement, during the assembly of the limiting member 33 and the partition member 31, the third insertion portion 331 may be inserted into the fourth insertion portion 313 in the third direction Z to achieve the fitting and mounting of the limiting member 33 and the partition member 31. The mounting process is simple and easy, which contributes to improving the assembly efficiency of the battery pack housing 100.

[0045] In some embodiments of this disclosure, a mounting sheet 314 is provided on the partition member 31, as shown in Figures 3 and 5. That is, the mounting sheet 314 may be positioned on the partition member 31. The mounting sheet 314 may be integrated with the partition member 31 or it may be detachable, and this is not particularly limited herein. The mounting sheet 314 is configured to mount the busbar for the battery 1 and the busbar for the power distribution box 4. Thus, by positioning the mounting sheet 314 on the partition member 31, an auxiliary function is added to the partition member 31, thereby providing a platform for mounting the busbar for the battery 1 and the busbar for the power distribution box 4.

[0046] In some embodiments of this disclosure, as shown in Figure 9, the partition member 31 includes a plurality of sub-partition members 315, which are in a lapping fit state in a first direction X of the battery pack housing 100 to form the partition member 31.

[0047] Specifically, the partition member 31 includes a plurality of sub-partition members 315, and the number of sub-partition members 315 is set according to specific needs. For example, the number of sub-partition members 315 may be two, three, four, or five, and this is not particularly limited herein. Furthermore, in a first direction X, the plurality of sub-partition members 315 are in a continuous overlapping and fitting state to form the partition member 31. As a specific example, three sub-partition members 315 are continuously overlapped to form one partition member 31. In the overlapping process of the sub-partition members 315, the sub-partition members 315 on both sides may be attached first, and then, during the attachment of the central sub-partition member 315, the overlapping area of ​​the central sub-partition member 315 is made to contact the overlapping areas of the sub-partition members 315 on both sides simultaneously, thereby restricting the central sub-partition member 315. Alternatively, the sub-partition members 315 may be attached sequentially, and this is not particularly limited herein. Therefore, by providing multiple partition sub-members 315, it is possible to select a suitable partition sub-member 315 based on the size of the battery pack housing 100 to meet various size requirements for the battery pack housing 100, thereby improving the versatility of the partition member 31.

[0048] As shown in Figure 9, when multiple partition sub-members 315 are continuously overlapped, the first snap-fit ​​portion 3151 and the second snap-fit ​​portion 3152 may be positioned within the overlapping region of two adjacent partition sub-members 315, respectively, with the first snap-fit ​​portion 3151 being either a snap tab or a snap slot, and the second snap-fit ​​portion 3152 being the other of either a snap tab or a snap slot. This arrangement allows two adjacent partition sub-members 315 to snap-fit ​​through their overlapping region, thereby improving the strength of the connection between the partition sub-members 315 and providing greater resistance to compressive forces caused by expansion from the foam adhesive 7.

[0049] In some embodiments of the present disclosure, as shown in Figure 9, the partition member 31 includes a plurality of partition sub-members 315, which are continuously overlapped and fitted together in a first direction X of the battery pack housing 100 to form the partition member 31. Two adjacent partition sub-members 315 together define a first assembly portion 311 within the overlapping region, and at least one support sub-member 322 is assembled to the first assembly portion 311.

[0050] Specifically, if the partition member 31 includes multiple sub-partition members 315, the support sub-member 322 may be fixedly attached to the corresponding sub-partition member 315 to transmit the compressive force caused by expansion on the sub-partition member 315 to the side frame 22 through the support sub-member 322. On the other hand, if multiple sub-partition members 315 are continuously overlapped in a first direction X, two adjacent sub-partition members 315 together define a first assembly 311 within the overlapping region. The defined first assembly 311 may be an assembly groove or a mounting boss, and the support sub-member 322 is attached to the first assembly 311. This arrangement allows the overlapping region of the sub-partition members 315 to be reused to form the first assembly 311, thereby reducing the number of specially arranged first assemblies 311. On the other hand, the first assembly portion 311, defined by attaching the support sub-member 322 to the overlapping region, also has a specific support and limiting effect on the overlapping region. As a result, the expansion-induced compressive force applied to the overlapping region of the partition sub-member 315 can be transmitted to the side frame 22, thereby preventing collapse and damage in the overlapping region.

[0051] In some embodiments of this disclosure, as shown in Figure 10, at least one support sub-member 322 is provided with a mounting hole 3221. That is, the mounting hole 3221 is located in the support sub-member 322, and an electrical element such as a circuit board may be attached using the support sub-member 322, thereby adding an auxiliary function to the support sub-member 322 and providing a base for attaching the electrical element.

[0052] In some embodiments of this disclosure, as shown in Figure 10, a positioning section 3222 is provided on at least one support sub-member 322. That is, the electrical element to be mounted may be positioned by arranging the positioning section 3222 on the support sub-member 322. Optionally, the positioning section 3222 includes, but is not limited to, positioning pins, positioning posts, and the like. This arrangement facilitates rapid positioning during mounting of the electrical element and improves assembly efficiency.

[0053] In some embodiments of the present disclosure, a stopper member 6 is positioned within the housing cavity 21, as shown in Figure 1. The stopper member 6 is located on the side of the partition member 31 and away from the battery 1, and is adapted to stop the partition member 31 and restrict its movement away from the battery 1.

[0054] Specifically, the stopping member 6 is placed inside the housing cavity 21 and fixedly attached to the tray 2. The attachment method includes, but is not limited to, welding and bolt connection. There may be multiple stopping members 6, and the number of stopping members 6 may be, for example, two, three, four, or five, but this is not particularly limited in this specification. For example, two stopping members 6 are placed inside the housing cavity 21, and the two stopping members 6 are located on both sides of the partition member 31, and are located on the side of the partition member 31 that is away from the battery 1. The stopping member 6 has a stopping effect and is configured to stop the partition member 31 and restrict the movement of the partition member 31 in the direction away from the battery 1. That is, in the process of inserting the partition member 31, the stopping member 6 may restrict the partition member 31 in a second direction Y. On the other hand, the stopping member 6 may provide support to the partition member 31 when the partition member 31 is subjected to a compressive force caused by expansion, and a portion of the compressive force caused by expansion that the partition member 31 receives is transmitted to the side frame 22 through the stopping member 6, thereby increasing the transmission routes for the compressive force caused by expansion, which contributes to further sharing a portion of the compressive force caused by expansion that the partition member 31 receives, and to preventing the partition member 31 from entering the power distribution space 24 formed between the partition member 31 and the side frame 22.

[0055] As shown in Figures 1 and 2, a battery pack 200 according to one embodiment of a second aspect of the present disclosure includes a battery 1 and a battery pack housing 100 according to an embodiment of the first aspect, wherein the battery 1 is mounted in a battery mounting space 23.

[0056] According to the battery pack 200 in this embodiment of the present disclosure, since the aforementioned battery pack housing 100 is provided, the compressive force caused by expansion that the partition member 31 receives can be distributed to the side frame 22 of the tray 2 through the support member 32, thereby enabling the partition member 31 to effectively withstand the compressive force caused by expansion from the foam adhesive 7, thereby preventing the partition member 31 from entering the power distribution space 24 formed between the partition member 31 and the side frame 22.

[0057] In some embodiments of this disclosure, as shown in Figure 2, there are multiple batteries 1, and each battery 1 is a cylindrical battery.

[0058] In some embodiments of the present disclosure, as shown in Figures 1 and 2 and in conjunction with Figure 5, the battery pack 200 further includes a power distribution box 4, which is positioned on the side frame 22 and at least partially within the power distribution space 24. The support member 32 includes a plurality of support sub-members 322, which are spaced apart in the longitudinal direction of the partition member 31, with at least one support sub-member 322 supported between the partition member 31 and the side frame 22 of the tray 2, and at least one support sub-member 322 supported between the partition member 31 and the power distribution box 4.

[0059] Specifically, the battery pack 200 further includes a power distribution box 4, which is mounted on the side frame 22 and located at least partially within the power distribution space 24. If the support member 32 includes a plurality of support sub-members 322, at least one support sub-member 322 is supported between the partition member 31 and the side frame 22 of the tray 2, and at least one support sub-member 322 is supported between the partition member 31 and the power distribution box 4. For example, if the support member 32 includes five support sub-members 322, one, two, three, or four support sub-members 322 can be arranged to be supported between the partition member 31 and the side frame 22 of the tray 2, and correspondingly, four, three, two, or one support sub-member 322 can be arranged to be supported between the partition member 31 and the power distribution box 4. Furthermore, the explanation is provided by using an example in which, as shown in Figures 1 and 5, two support sub-members 322 are positioned between the partition member 31 and the side frame 22 of the tray 2, and three support sub-members 322 are positioned between the partition member 31 and the power distribution box 4. The two support sub-members 322 are located on both sides of the power distribution box 4 and are positioned perpendicularly between the partition member 31 and the side frame 22 of the tray 2, while the three support sub-members 322 are positioned perpendicularly between the partition member 31 and the power distribution box 4. When the partition member is subjected to a compressive force due to expansion from the foam adhesive 7, a portion of the compressive force due to expansion is transmitted directly to the side frame 22 through the two support sub-members 322 on both sides of the power distribution box 4, and another portion of the compressive force due to expansion is transmitted to the power distribution box 4 through the three support sub-members 322 and indirectly to the side frame 22 through the power distribution box 4. This arrangement not only allows the compression force caused by expansion to be transmitted to the side frame 22 using the power distribution box 4, but also increases the surface area of ​​the transmission area, which contributes to improved stability during force transmission and indirectly improves the ability of the partition member 31 to withstand the compression force caused by expansion from the foam adhesive 7.

[0060] As shown in Figure 11, an electrical device 300 according to one embodiment of the third aspect of the present disclosure includes a battery pack 200 according to an embodiment of the second aspect.

[0061] According to the electrical device 300 in this embodiment of the present disclosure, since the aforementioned battery pack 200 is provided, the compressive force caused by expansion that the partition member 31 receives can be distributed to the side frame 22 of the tray 2 through the support member 32, thereby enabling the partition member 31 to effectively withstand the compressive force caused by expansion from the foam adhesive 7, thereby preventing the partition member 31 from entering the power distribution space 24 formed between the partition member 31 and the side frame 22.
