Technical Field

[0001] Cross - reference to related applications This disclosure claims the priority of Chinese Patent Application No. 202310488301.2, filed on April 28, 2023, and the entire content thereof is incorporated herein by reference.

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

Background Art

[0003] In the prior art, the exhaust plastic brackets of existing battery pack containers are not arranged with an adhesive blocking structure. When a foaming adhesive is filled between cells, the foaming adhesive will overflow to every location between cells inside the battery pack container. The foaming adhesive can easily cover and block the explosion - proof part of the battery cell and the exhaust structure of the battery pack container. Therefore, the gas inside the battery cell cannot be discharged when the cell undergoes thermal runaway. The foaming adhesive can further easily cover other components of the battery pack, which may reduce the safety during the use of the battery pack.

Summary of the Invention

[0004] This disclosure aims to solve at least one of the technical problems in the prior art mentioned above. Accordingly, this disclosure provides a battery pack container that prevents the foaming adhesive from overflowing from the adhesive filling area and improves the safety during the use of the battery pack.

[0007] The battery pack container according to this disclosure a tray with an accommodation cavity formed therein, and Mounting brackets installed inside the housing cavity, The first adhesive barrier plate and the second adhesive barrier plate are located within the containment cavity and are both attached to the mounting bracket. The system includes a first adhesive barrier plate, a second adhesive barrier plate, a mounting bracket, and a tray, all of which define an adhesive filling area, with a first exhaust passage formed on the side of the mounting bracket away from the adhesive filling area, and the exhaust port of the first exhaust passage located outside the adhesive filling area.

[0008] According to the battery pack container of this disclosure, the first adhesive barrier plate, the second adhesive barrier plate, the mounting bracket, and the tray all define an adhesive filling area, which is beneficial because it prevents foamed adhesive from overflowing from the adhesive filling area and reduces the risk of foamed adhesive covering and blocking the explosion-proof parts of the battery cells and the exhaust structure of the battery pack container, thereby allowing gases inside the battery cells to be discharged in the event of thermal runaway of the battery cells. Furthermore, the risk of foamed adhesive covering other components of the battery pack is reduced, ensuring the operational performance of other components of the battery pack and ultimately improving safety during use of the battery pack.

[0009] The battery pack according to this disclosure includes a plurality of battery cells and a battery pack container as described above, wherein the plurality of battery cells are mounted on a mounting bracket, and the plurality of explosion-proof parts of the battery cells correspond one-to-one with the plurality of discharge ports of the mounting bracket.

[0010] According to the battery pack of this disclosure, if thermal runaway occurs in the battery cell, the exhaust port can reliably avoid the explosion-proof section, which is normally open, and the gas discharged from inside the battery cell flows from the exhaust port into the first exhaust passage, and the gas flows along the first exhaust passage, and as a result the gas inside the battery cell is rapidly discharged, which is beneficial in reducing the internal pressure of the battery cell and further reduces the risk of the battery cell exploding.

Therefore, it should be understood that the present disclosure cannot be construed as being limited thereby.

[0017] Furthermore, the terms "first" and "second" are for the purpose of description only, and should not be understood as indicating or implicitly indicating the relative importance or number of the indicated technical features. Therefore, the features defined as "first" or "second" may include one or more of the features explicitly or implicitly. In the description of the present disclosure, "a plurality" means at least two, such as two, three, etc., unless specifically and explicitly defined otherwise.

[0018] In this application, unless specifically specified and defined otherwise, terms such as "attached", "connected", "joined", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated, mechanically connected, electrically connected, or communicating with each other, directly connected, or indirectly connected through an intermediate medium, or the two elements may be in internal communication or interacting with each other. A person skilled in the art can understand the specific meaning of the above-mentioned terms in this disclosure according to the specific situation.

[0019] Hereinafter, a battery pack container according to an embodiment of the present disclosure will be described with reference to FIGS. 1 to 12. The battery pack container can be applied to a battery pack, but the present disclosure is not limited thereto. The battery pack container can also be applied to other devices where the battery pack container needs to be provided. In the present disclosure, the battery pack container applied to a battery pack is described as an example.

[0020] According to one embodiment of the battery pack container of the present disclosure, as shown in Figures 1 to 12, the battery pack container includes a tray 1, a mounting bracket 2, a first adhesive barrier plate 3, and a second adhesive barrier plate 4. A housing cavity 10 is formed in the tray 1, the mounting bracket 2 is mounted in the housing cavity 10, the first adhesive barrier plate 3 and the second adhesive barrier plate 4 are positioned in the housing cavity 10 and both are mounted on the mounting bracket 2, and the first adhesive barrier plate 3, the second adhesive barrier plate 4, the mounting bracket 2, and the tray 1 together define an adhesive filling area 5. A first exhaust passage 2a is formed on one side of the mounting bracket 2 away from the adhesive filling area 5, and the exhaust port of the first exhaust passage 2a is located outside the adhesive filling area 5. The adhesive filling area 5 can be filled with colloid, which can be made as a foamed adhesive. The first adhesive barrier plate 3, the second adhesive barrier plate 4, the mounting bracket 2, and the tray 1 can block the foamed adhesive from flowing out of the adhesive filling area 5, which is beneficial because it prevents the foamed adhesive from blocking the exhaust port of the first exhaust passage 2a and ensures a smooth flow through the first exhaust passage 2a.

[0021] As shown in Figures 1 and 2, the height direction of the battery pack container is the vertical direction shown in Figures 1 and 2. Note that the first exhaust passage 2a is formed on the side of the mounting bracket 2 away from the adhesive-filled area 5. If the mounting bracket 2 is positioned in the direction shown in Figure 2, it will be understood that the first exhaust passage 2a is formed on the lower surface of the mounting bracket 2. All of the battery cells 100 of the battery pack are attached to the mounting bracket 2, and the battery cells 100 are placed in the adhesive-filled area 5, which is filled with foamed adhesive, so that the battery cells 100 are fixed within the adhesive-filled area 5. When the foamed adhesive flows into the foamed adhesive-filled area 5, the first adhesive barrier plate 3 and the second adhesive barrier plate 4 can block the foamed adhesive from flowing out of the foamed adhesive-filled area 5, thereby reducing the risk of the foamed adhesive covering and blocking the explosion-proof parts of the battery cells 100 and the exhaust structure of the battery pack container. The exhaust port of the first exhaust passage 2a is in communication with the exhaust structure of the battery pack container, so that if the battery cell 100 experiences thermal runaway, the gas inside the battery cell 100 can be discharged. The risk of foam adhesive covering other components of the battery pack can be reduced, the operational performance of other components of the battery pack can be guaranteed, and thereby the safety of using the battery pack can be improved.

[0022] Thus, the first adhesive barrier plate 3, the second adhesive barrier plate 4, the mounting bracket 2, and the tray 1 all define an adhesive filling area 5, which is beneficial because it prevents foamed adhesive from overflowing from the adhesive filling area 5 and reduces the risk of foamed adhesive covering and blocking the explosion-proof section of the battery cell 100 and the exhaust structure of the battery pack container. Gas inside the battery cell can be released if the battery cell 100 experiences thermal runaway. Furthermore, the risk of foamed adhesive covering other components of the battery pack is reduced, ensuring the operational performance of other components of the battery pack, thereby improving safety during use of the battery pack.

[0023] In some embodiments of this disclosure, as shown in Figures 1 and 3, the first adhesive barrier plate 3 is positioned opposite and spaced apart from the second adhesive barrier plate 4 in order to form an adhesive filling area 5 between the first adhesive barrier plate 3 and the second adhesive barrier plate 4. Furthermore, as shown in Figure 1, when the mounting bracket 2 is arranged in the direction shown in Figure 1, the first adhesive barrier plate 3 and the second adhesive barrier plate 4 are positioned at both ends of the mounting bracket 2 in the longitudinal direction (i.e., front-to-back direction), and both the first adhesive barrier plate 3 and the second adhesive barrier plate 4 are positioned on the upper surface of the mounting bracket 2 in the thickness direction (i.e., up-to-down direction). Furthermore, the first exhaust passage 2a is positioned on the underside of the mounting bracket 2 and can extend in a straight or curved shape in the longitudinal direction (i.e., front-to-back direction) of the mounting bracket 2, with exhaust ports at one or both ends of the first exhaust passage 2a facing the first adhesive barrier plate 3 and the second adhesive barrier plate 4, thereby forming the adhesive filling area 5 between the first adhesive barrier plate 3 and the second adhesive barrier plate 4. This prevents foamed adhesive from overflowing from the first adhesive barrier plate 3 and / or the second adhesive barrier plate 4 out of the adhesive filling area 5 and blocking the exhaust ports of the first exhaust passage 2a, thereby improving safety when using the battery pack.

[0024] In other embodiments of this disclosure, the first adhesive barrier plate 3 and the second adhesive barrier plate 4 may be arranged adjacent to each other, or they may be understood to be adjacent and connected. In this case, the first adhesive barrier plate 3 is located at one end of the mounting bracket 2 in the longitudinal direction (i.e., front-to-back direction), the second adhesive barrier plate 4 is located at one end of the mounting bracket 2 in the width direction (i.e., left-to-right direction), and both the first adhesive barrier plate 3 and the second adhesive barrier plate 4 are located on the upper surface of the mounting bracket 2. Furthermore, the first exhaust passage 2a is located on the lower surface of the mounting bracket 2, and the first exhaust passage 2a may extend in a curved shape. The exhaust port at one end of the first exhaust passage 2a is located at the longitudinal end (i.e., front-to-back direction) of the mounting bracket 2, opposite to the first adhesive barrier plate 3, and / or the exhaust port at the other end of the first exhaust passage 2a is located at the widthwise end (i.e., left-to-right direction) of the mounting bracket 2, opposite to the second adhesive barrier plate 4. When the first adhesive barrier plate 3 and the second adhesive barrier plate 4 are fixedly assembled to the mounting bracket 2, and the mounting bracket 2, the first adhesive barrier plate 3, and the second adhesive barrier plate 4 are all located within the housing cavity 10, the mounting bracket 2, the first adhesive barrier plate 3, the second adhesive barrier plate 4, and the tray together define an adhesive filling area 5, thereby reducing the risk of foam adhesive covering and blocking the explosion-proof section of the battery cell 100 and the exhaust structure of the battery pack container. Gas inside the battery cell 100 can be discharged in the event of thermal runaway of the battery cell 100. Furthermore, the risk of foam adhesive covering other components of the battery pack is reduced, ensuring the operational performance of other components and ultimately improving safety during use.

[0025] In some embodiments of this disclosure, as shown in Figures 1 and 4, the mounting bracket 2 has an exhaust port 2b that communicates with a first exhaust passage 2a, and the exhaust port 2b is adapted to correspond to the explosion-proof portion of the battery cell 100. Furthermore, as shown in Figure 1, a plurality of battery cells 100 are arranged in the battery pack container, and the plurality of battery cells 100 can be arranged in a series to form a battery assembly, and the plurality of battery cells 100 can be combined to form a plurality of battery assemblies. The battery cells 100 are fixedly attached to the upper surface of the mounting bracket 2 in the height direction (i.e., vertical direction) of the battery pack container, as shown in Figure 2, thereby achieving the effect of assembling the battery cells 100 within the adhesive-filled area 5.

[0026] The adhesive-filled area 5 is filled with foam adhesive, and the battery cell 100 is bonded between the first adhesive barrier plate 3 and the second adhesive barrier plate 4 in the longitudinal direction of the battery pack container, that is, the battery cell 100 is bonded within the adhesive-filled area 5. At the same time, the foam adhesive has the effect of bonding between two adjacent battery cells 100, thereby improving the connection strength between two adjacent battery cells 100 and improving the safety of the battery pack during use. As a result, filling the adhesive-filled area 5 with foam adhesive improves the stability of the battery cell 100 within the adhesive-filled area 5, which is beneficial because it ensures that the battery cell 100 is securely attached within the adhesive-filled area 5.

[0027] Furthermore, as shown in Figure 4, when the mounting bracket 2 is arranged in the direction shown in Figure 4, the first exhaust passage 2a is formed at the bottom of the mounting bracket 2 in the thickness direction (i.e., vertical direction), and the exhaust port 2b is configured as a through hole that penetrates the mounting bracket 2 in the thickness direction, thereby achieving the effect of the exhaust port 2b communicating with the first exhaust passage 2a.

[0028] Furthermore, when the battery cell 100 is attached to the mounting bracket 2, the explosion-proof portion of the battery cell 100 is positioned in the thickness direction of the mounting bracket 2 to correspond to the exhaust port 2b. In this way, if thermal runaway occurs in the battery cell 100, the exhaust port 2b can avoid the explosion-proof portion, and the explosion-proof portion remains normally open. The gas discharged from inside the battery cell 100 flows from the exhaust port 2b into the first exhaust passage 2a, and the gas flows along the first exhaust passage 2a. As a result, the gas inside the battery cell 100 is quickly discharged, which is beneficial because it reduces the internal pressure of the battery cell 100 and further reduces the risk of explosion of the battery cell 100.

[0029] When thermal runaway occurs in battery cell 100, the internal pressure of battery cell 100 increases. When the internal pressure of battery cell 100 reaches a certain threshold, the gas inside battery cell 100 rushes into the explosion-proof section, separating the explosion-proof section from battery cell 100. The gas inside battery cell 100 is rapidly released, thereby reducing the internal pressure of battery cell 100, improving the safety of the battery pack during use, and ultimately reducing the risk of explosion of battery cell 100.

[0030] Therefore, by positioning the discharge port 2b in accordance with the explosion-proof section of the battery cell 100, the discharge port 2b avoids the explosion-proof section in the thickness direction of the mounting bracket 2, avoiding the risk of the mounting bracket 2 blocking the explosion-proof section, ensuring that the explosion-proof section remains open in the event of thermal runaway of the battery cell 100, thereby guaranteeing the safety of the battery cell 100 during use, and further guaranteeing the safety of the battery pack during use.

[0031] In some embodiments of the present disclosure, as shown in Figures 3, 4, and 11, the first adhesive-blocking plate 3 may have a first insertion portion 31, and the mounting bracket 2 may have a second insertion portion 22, the first insertion portion 31 being matched in a push-fit manner with the second insertion portion 22 for assembling the first adhesive-blocking plate 3 to the mounting bracket 2. Furthermore, as shown in Figure 3, the first insertion portion 31 is located at the bottom of the first adhesive-blocking plate 3 in the height direction (i.e., vertical direction), and the first insertion portion 31 may be made as a protruding structure, the formed protruding structure projecting away from the first adhesive-blocking plate 3. The second insertion portion 22 may be configured as a recessed structure that fits the first insertion portion 31, and as shown in Figure 11, the second insertion portion 22 is configured as a recessed structure that is recessed in the thickness direction of the mounting bracket 2 from the upper surface of the mounting bracket 2 toward the inside of the mounting bracket 2. The first insertion portion 31 is adapted to extend into the second insertion portion 22 during the process of fitting the first insertion portion 31 with the second insertion portion 22 in an insert manner, thereby achieving the effect of fitting the first insertion portion 31 with the second insertion portion 22 in an insert manner. In this way, the effect of fixing and assembling the first adhesive barrier plate 3 onto the mounting bracket 2 is achieved.

[0032] In some embodiments of the present disclosure, as shown in Figures 4 and 11, the orthographic projection of the first insertion portion 31 is offset from the orthographic projection of the first exhaust passage 2a in the height direction of the battery pack container.

[0033] Furthermore, as shown in Figures 4 and 11, the second insertion portion 22 is configured as a recessed structure that is recessed inward from the upper surface of the mounting bracket 2 in the thickness direction of the mounting bracket 2, and the first exhaust passage 2a is configured as a recessed structure that is recessed inward from the lower surface of the mounting bracket 2 in the height direction of the battery pack container (i.e., the thickness direction of the mounting bracket 2). The orthographic projection of the second insertion portion 22 is offset from the orthographic projection of the first exhaust passage 2a. Therefore, when the first insertion portion 31 is inserted into the second insertion portion 22, the effect of offsetting the orthographic projection of the first insertion portion 31 and the orthographic projection of the first exhaust passage 2a is achieved, preventing the first insertion portion 31 from extending into the first exhaust passage 2a, thereby avoiding the first insertion portion 31 blocking the first exhaust passage 2a and ensuring the openness of the first exhaust passage 2a.

[0034] The second insertion portion 22 is spaced apart from the discharge port 2b in the longitudinal direction of the mounting bracket 2, so that when the first insertion portion 31 is inserted into the second insertion portion 22, the first insertion portion 31 does not extend into the discharge port 2b, thereby preventing the first insertion portion 31 from obstructing the discharge port 2b and ensuring the openness of the discharge port 2b.

[0035] In some embodiments of this disclosure, as shown in Figures 1 and 11, the tray 1 has a limiting portion 1c, the limiting portion 1c is located within the housing cavity 10, the limiting portion 1c is located on the side of the first adhesive blocking plate 3 away from the adhesive filling area 5, and the limiting portion 1c is adapted to abut against and limit the first adhesive blocking plate 3. The limiting portion 1c may further be configured as a plate-like structure, as shown in Figure 1, and the limiting portion 1c may be located within the housing cavity 10 and fixedly connected to the tray 1. As shown in Figure 11, the limiting portion 1c is located in the longitudinal direction of the battery pack container on the side of the first adhesive blocking plate 3 away from the adhesive filling area 5, and the orthographic projection of the limiting portion 1c and the orthographic projection of the first adhesive blocking plate 3 have an overlapping region in the longitudinal direction of the battery pack container. In this way, a mutual restricting effect is achieved between the limiting portion 1c and the first adhesive blocking plate 3 in the longitudinal direction of the battery pack container, and when the first adhesive blocking plate 3 tends to move toward the limiting portion 1c, the limiting portion 1c reliably supports the first adhesive blocking plate 3, thereby ensuring that the first adhesive blocking plate 3 is securely attached and fixed to the mounting bracket 2.

[0036] The limiting portion 1c is further positioned on the side of the mounting bracket 2 away from the adhesive-filled area 5 in the longitudinal direction of the battery pack container when the mounting bracket 2 is placed inside the housing cavity 10. The orthographic projection of the limiting portion 1c and the orthographic projection of the mounting bracket 2 have overlapping areas, and therefore a mutual restricting effect is achieved between the limiting portion 1c and the mounting bracket 2 in the longitudinal direction of the battery pack container. When the mounting bracket 2 tends to move toward the limiting portion 1c, the limiting portion 1c reliably supports the mounting bracket 2, thereby ensuring that the mounting bracket 2 is securely installed inside the housing cavity 10.

[0037] In some embodiments of the present disclosure, as shown in Figures 2 and 5, the battery pack container may further include a limiting member 6, which is inserted into a first adhesive barrier plate 3, and together the limiting member 6 and the first adhesive barrier plate 3 define a mounting passage 6a. The mounting passage 6a is configured for mounting piping. The piping may be wiring harness piping for electrically connecting the battery cells 100, heat exchange medium piping for heat exchange of the battery cells 100, or other piping fixtures that need to be mounted to the adhesive filling area 5.

[0038] Furthermore, as shown in Figure 5, the first adhesive barrier plate 3 has a mounting notch 3a. When the first adhesive barrier plate 3 is arranged in the direction shown in Figure 5, the mounting notch 3a is located at one end of the first adhesive barrier plate 3 on the side away from the first insertion portion 31 in the height direction, that is, the open mounting notch 3a is formed at the upper end of the first adhesive barrier plate 3, and the engineer arranges the piping through the mounting notch 3a into the mounting passage 6a, thereby achieving the effect of inserting the piping into the first adhesive barrier plate 3.

[0039] Furthermore, as shown in Figure 2, when the first adhesive barrier plate 3 is positioned in the direction shown in Figure 2 and the limiting member 6 is fitted to the first adhesive barrier plate 3 by a push-in method, the mounting passage 6a is defined within the mounting notch 3a. That is, both the limiting member 6 and the first adhesive barrier plate 3 define the mounting passage 6a, achieving the effect of restricting the piping within the mounting passage 6a when the piping is inserted into the mounting passage 6a, thereby preventing the piping from separating from the first adhesive barrier plate 3.

[0040] Furthermore, when the limiting member 6 is fitted to the first adhesive barrier plate 3 by a plug-in method, the orthographic projection of the limiting member 6 in the thickness direction (i.e., the front-to-back direction) of the first adhesive barrier plate 3 coincides at least partially with the orthographic projection of the mounting notch 3a, and the limiting member 6 blocks the area within the mounting notch 3a that is not the mounting passage in the thickness direction of the first adhesive barrier plate 3. This effectively avoids the risk of foamed adhesive overflowing from the adhesive filling area 5 through the area within the mounting notch 3a that is not the mounting passage, thereby improving safety when using the battery pack.

[0041] Furthermore, if there is a gap between the pipe and the inner wall of the mounting passage 6a after the pipe has been inserted into the mounting passage 6a, the filler material can be used to fill the gap between the pipe and the inner wall of the mounting passage 6a. This effectively seals the gap between the pipe and the inner wall of the mounting passage 6a, avoiding the risk of the foam adhesive overflowing from the adhesive-filled area 5 through the gap between the pipe and the inner wall of the mounting passage 6a, and improving safety when using the battery pack.

[0042] In some embodiments of this disclosure, as shown in Figure 5, the limiting member 6 has a third insertion portion 63, and the first adhesive blocking plate 3 has a fourth insertion portion 34, and the third insertion portion 63 is fitted into the fourth insertion portion 34 in an insert manner for assembling the limiting member 6 to the first adhesive blocking plate 3. Furthermore, as shown in Figure 5, when the limiting member 6 and the first adhesive blocking plate 3 are arranged in the direction shown in Figure 5, both ends of the limiting member 6 in the width direction (i.e., left-right direction) of the limiting member 6 each have a third insertion portion 63, and the third insertion portion 63 may be configured as an insertion groove. The insertion groove is recessed toward the inside of the limiting member 6, and the insertion groove extends in the height direction (i.e., vertical direction) of the limiting member 6. Therefore, in the process of the third insertion portion 63 fitting into the fourth insertion portion 34 in insertion mode, the third insertion portion 63 is fitted into the fourth insertion portion 34 in the vertical direction shown in Figure 5. The vertical direction shown in Figure 5 is the insertion direction of the third insertion portion 63 and the fourth insertion portion 34.

[0043] Furthermore, as shown in Figure 5, the first adhesive blocking plate 3 has two fourth insertion portions 34 arranged opposite each other in the width direction (i.e., left-right direction) of the first adhesive blocking plate 3, and each of the fourth insertion portions 34 is arranged along the edge of the mounting notch 3a. Therefore, in the insertion process between the limiting member 6 and the first adhesive blocking plate 3, the two third insertion portions 63 correspond one-to-one with the two fourth insertion portions 34, thereby achieving the effect of the third insertion portions 63 fitting into the fourth insertion portions 34 in an insert method, and consequently achieving the effect of the limiting member 6 fitting into the first adhesive blocking plate 3 in an insert method.

[0044] Furthermore, as shown in Figure 5, the fourth insertion portion 34 may be configured as an insertion plate. Therefore, in the process of fitting the limiting member 6 into the first adhesive blocking plate 3 by insertion, the insertion plate is adapted to extend into the insertion groove, thereby achieving the effect of fitting the third insertion portion 63 into the fourth insertion portion 34 by insertion, and thereby achieving the effect of fitting the limiting member 6 into the first adhesive blocking plate 3 by insertion.

[0045] Furthermore, as shown in Figure 5, with respect to the third insertion portion 63 and the fourth insertion portion 34 of this disclosure, the third insertion portion 63 is configured as an insertion groove and the fourth insertion portion 34 is configured as an insertion plate. Therefore, when the third insertion portion 63 is fitted into the fourth insertion portion 34 in an insertion manner, the effect of restricting the relative position between the limiting member 6 and the first adhesive blocking plate 33 in the thickness direction (i.e., the front-to-back direction) of the first adhesive blocking plate 3 is realized. As a result, the effect of the limiting member 6 fitting into and restricting the first adhesive blocking plate 33 is realized, and the risk of the limiting member 6 and the first adhesive blocking plate 3 separating from each other is reduced.

[0046] In some embodiments of the present disclosure, as shown in Figure 5, the first adhesive blocking plate 3 has a first restricting structure 32, and the restricting member 6 has a second restricting structure 62, the first restricting structure 32 fits into and restricts the second restricting structure 62, and restricts the restricting member 6 in the insertion direction of the third insertion portion 63 and the fourth insertion portion 34.

[0047] Furthermore, the first limiting structure 32 may be configured as a limiting projection, and the second limiting structure 62 may be configured as a limiting recess. The limiting projection is adapted to fit with the limiting recess to restrict, thereby achieving the effect of the first limiting structure 32 fitting with the second limiting structure 62 to restrict. As shown in Figure 5, when the first adhesive blocking plate 3 and the limiting member 6 are arranged in the direction shown in Figure 5, the first limiting structure 32 protrudes away from the first adhesive blocking plate 3 in the thickness direction (i.e., the front-to-back direction) of the first adhesive blocking plate 3, and therefore the first limiting structure 32 is configured as a limiting projection. The second limiting structure 62 is recessed inward toward the limiting member 6 in the thickness direction (i.e., the front-to-back direction) of the limiting member 6, and therefore the second limiting structure 62 is configured as a limiting recess. When the limiting member 6 is fitted into the first adhesive barrier plate 3 by insertion, the first limiting structure 32 is positioned within the second limiting structure 62, and the orthographic projection of the first limiting structure 32 and the orthographic projection of the second limiting structure 62 have an overlapping region in the height direction of the first adhesive barrier plate 3. Therefore, in the height direction of the first adhesive barrier plate 3, the limiting member 6 and the first adhesive barrier plate 3 mutually restrict each other, reducing the risk of the limiting member 6 separating from the first adhesive barrier plate 3. This ensures that the limiting member 6 is securely inserted into the first adhesive barrier plate 3, thereby effectively avoiding the risk of foamed adhesive overflowing from the adhesive filling area 5 through areas within the mounting notch 3a that are not mounting passages, and ultimately improving safety when using the battery pack.

[0048] In some embodiments of the present disclosure, as shown in Figures 3, 6, and 12, the second adhesive barrier plate 4 has a fifth insertion portion 45, and the mounting bracket 2 has a sixth insertion portion 26, the fifth insertion portion 45 is fitted into the sixth insertion portion 26 in an insert manner for assembling the second adhesive barrier plate 4 to the mounting bracket 2.

[0049] Furthermore, as shown in Figure 3, in the thickness direction (i.e., vertical direction) of the mounting bracket 2, both the sixth insertion portion 26 and the second insertion portion 22 are positioned on the upper surface of the mounting bracket 2, thereby ensuring that both the first adhesive blocking plate 3 and the second adhesive blocking plate 4 are positioned on the same side of the mounting bracket 2. In the length direction (i.e., front-to-back direction) of the mounting bracket 2, the second insertion portion 22 and the sixth insertion portion 26 are positioned at both ends of the mounting bracket 2, respectively, so that the first adhesive blocking plate 3 faces the second adhesive blocking plate 4 and is separated from the second adhesive blocking plate 4, so that both are positioned on the mounting bracket 2, and consequently, so that the adhesive filling area 5 is formed between the first adhesive blocking plate 3 and the second adhesive blocking plate 4.

[0050] Furthermore, as shown in Figure 12, when the second adhesive blocking plate 4 is arranged in the direction shown in Figure 12, the fifth insertion portion 45 is positioned at the lower end of the second adhesive blocking plate 4 in the height direction (i.e., vertical direction) of the second adhesive blocking plate 4, and the fifth insertion portion 45 may be configured as a plate-like structure, and the formed plate-like structure extends away from the second adhesive blocking plate 4. As shown in Figure 12, when the mounting bracket 2 is arranged in the direction shown in Figure 12, the sixth insertion portion 26 may be configured as a recessed structure that fits the fifth insertion portion 45. The sixth insertion portion 26 may be configured as a recessed structure that is recessed inward from the upper surface of the mounting bracket 2 towards the inside of the mounting bracket 2 in the thickness direction (i.e., vertical direction) of the mounting bracket 2. In the process of the fifth insertion portion 45 engaging with the sixth insertion portion 26 by an insertion method, the fifth insertion portion 45 extends into the sixth insertion portion 26, thereby achieving the effect of the fifth insertion portion 45 engaging with the sixth insertion portion 26 by an insertion method, and thereby achieving the effect of fixing and assembling the second adhesive barrier plate 4 onto the mounting bracket 2.

[0051] Furthermore, as shown in Figure 12, according to this disclosure, in one embodiment, the fifth insertion portion 45 is configured as a plate-like structure, and the sixth insertion portion 26 is configured as a recessed structure. When the fifth insertion portion 45 is fitted into the sixth insertion portion 26 by an insertion method, the risk of the foamed adhesive overflowing from the adhesive-filled area 5 through the gap between the fifth insertion portion 45 and the sixth insertion portion 26 is reduced, thereby improving safety when using the battery pack.

[0052] In some embodiments of this disclosure, as shown in Figure 12, the limiting boss 41 is positioned on the side of the second adhesive blocking plate 4 away from the adhesive filling area 5, and the limiting boss 41 abuts against the upper surface of the mounting bracket 2. In this way, the mounting bracket 2 provides the effect of supporting the second adhesive blocking plate 4 in the thickness direction (i.e., vertical direction) of the mounting bracket 2, improving the stability of the second adhesive blocking plate 4, and thus ensuring that the second adhesive blocking plate 4 is securely attached to the mounting bracket 2.

[0053] Furthermore, as shown in Figure 12, when the second adhesive blocking plate 4 is arranged in the direction shown in Figure 12, the limiting boss 41 is positioned close to one end of the sixth insertion portion 26 in the height direction (i.e., vertical direction) of the second adhesive blocking plate 4, the limiting boss 41 protrudes laterally away from the second adhesive blocking plate 4 in the thickness direction of the second adhesive blocking plate 4, and the limiting boss 41 is perpendicular to the sixth insertion portion 26. When the fifth insertion portion 45 is fitted into the sixth insertion portion 26 by a push-in method, the limiting boss 41 abuts against the mounting bracket 2 in the thickness direction of the mounting bracket 2. In this way, the effect of the mounting bracket 2 supporting the second adhesive blocking plate 4 is realized, the stability of the second adhesive blocking plate 4 is further improved, and therefore the second adhesive blocking plate 4 is securely attached to the mounting bracket 2.

[0054] In some embodiments of this disclosure, as shown in Figure 9, the second adhesive barrier plate 4 abuts against the lateral beam 1b of the tray 1, and both the mounting bracket 2 and the first adhesive barrier plate 3 abut against the lateral beam 1b. When the first adhesive barrier plate 3 and the second adhesive barrier plate 4 are positioned within the housing cavity and attached to the mounting bracket 2, the mounting bracket 2, the first adhesive barrier plate 3, the second adhesive barrier plate 4, and the lateral beam 1b together define an adhesive filling area 5, thereby preventing the foamed adhesive from overflowing from the adhesive filling area 5 and reducing the risk of the foamed adhesive covering and blocking the explosion-proof section of the battery cell 100 and the exhaust structure of the battery pack container. Gas inside the battery cell 100 can be discharged in the event of thermal runaway of the battery cell 100. Furthermore, the risk of the foamed adhesive covering other components of the battery pack is reduced, the operational performance of other components of the battery pack can be guaranteed, and thus the safety of the battery pack during use can be improved. Furthermore, the second adhesive barrier plate 4 is in contact with the lateral beam 1b of the tray 1, and both the mounting bracket 2 and the first adhesive barrier plate 3 are in contact with the lateral beam 1b. This is also beneficial because it improves the stability of the second adhesive barrier plate 4, as well as the stability of the mounting bracket 2 and the first adhesive barrier plate 3, thereby reducing the risk of foam adhesive overflowing from the adhesive filling area 5.

[0055] Furthermore, as shown in Figure 9, when the battery pack container is arranged in the direction shown in Figure 9, both ends of the mounting bracket 2 abut against the lateral beam 1b in the width direction (i.e., left-right direction) of the battery pack container, and both ends of the first adhesive barrier plate 3 abut against the lateral beam 1b. In addition, the mounting bracket 2, the first adhesive barrier plate 3, the second adhesive barrier plate, and the lateral beam 1b all define an adhesive-filled area 5 within the housing cavity 10, thereby preventing overflow of the adhesive-filled area 5, reducing the risk of foamed adhesive covering other components of the battery pack, ensuring the operational performance of other components of the battery pack, and ultimately improving safety during use of the battery pack.

[0056] Furthermore, as shown in Figure 9, the tray 1 may include a bottom plate 1a and a side beam 1b, and the side beam 1b may be configured as a closed-loop beam structure with an approximately "□" shape. As shown in Figure 10, when the tray 1 is arranged in the direction of Figure 10, in the height direction (i.e., vertical direction) of the tray 1, the bottom plate 1a is positioned at the lower end of the side beam 1b, and both the bottom plate 1a and the side beam 1b define the containment cavity 10, thereby achieving the effect of forming the containment cavity 10 within the tray 1.

[0057] In some embodiments of the present disclosure, as shown in Figures 8 and 12, a second exhaust passage 4a is formed on the side of the second adhesive barrier plate 4 away from the first adhesive barrier plate 3, and the second exhaust passage 4a is in communication with the first exhaust passage 2a. The second exhaust passage 4a can be in communication with the exhaust structure of the battery pack container, so that gas in the first exhaust passage 2a can be discharged from the battery pack container through the second exhaust passage 4a, which is beneficial as it improves safety when the battery pack is in use. As shown in Figure 12, the second exhaust passage 4a is formed on the side of the second adhesive barrier plate 4 facing the lateral beam 1b of the tray 1. The second exhaust passage 4a is in communication with the first exhaust passage 2a. Therefore, if thermal runaway occurs in the battery cell 100, the gas discharged from the battery cell 100 flows from the exhaust port 2b into the first exhaust passage 2a, flows along the first exhaust passage 2a to the second exhaust passage 4a, and quickly releases the gas inside the battery cell 100. This is beneficial because it reduces the internal pressure of the battery cell 100. Furthermore, the gas can be discharged from the battery pack container through the exhaust structure, further reducing the risk of explosion of the battery cell 100, thereby improving the safety of the battery pack during use.

[0058] In some embodiments of the present disclosure, as shown in Figure 12, a portion of the second adhesive barrier plate 4 abuts against the lateral beam 1b of the tray 1, and a portion of the second adhesive barrier plate 4 is recessed toward the direction toward the first adhesive barrier plate 3 to form a second exhaust passage 4a. In some embodiments of the present disclosure, in the height direction of the second adhesive barrier plate 4 (i.e., the vertical direction shown in Figure 12), the upper half of the second adhesive barrier plate 4 is adapted to abut against the lateral beam 1b, thereby achieving the effect of the second adhesive barrier plate 4 abutting against the lateral beam 1b and thereby improving the stability of the second adhesive barrier plate 4. The second exhaust passage 4a is formed in the lower half of the second adhesive barrier plate 4, and therefore the second exhaust passage 4a communicates with the first exhaust passage 2a, thereby achieving the effect of the second exhaust passage 4a communicating with the first exhaust passage 2a and thereby improving safety when using the battery pack. Therefore, the second adhesive barrier plate 4 according to the embodiment of the present disclosure is beneficial because it improves the stability of the second adhesive barrier plate 4, and at the same time, the effect of forming a second exhaust passage 4a on the second adhesive barrier plate 4 is realized, so the internal structure of the battery pack container becomes more compact, the utilization rate of the housing cavity 10 is improved, the mass of the second adhesive barrier plate 4 is reduced, and the lightweight effect of the second adhesive barrier plate 4 is realized. In this disclosure, as shown in Figure 12, one embodiment is described in which the second exhaust passage 4a is configured as a recessed structure, and in the thickness direction (i.e., front-to-back direction) of the second adhesive barrier plate 4, the recessed structure formed by the second exhaust passage 4a is recessed from the side surface of the second exhaust passage 4a facing the lateral beam 1b toward the inside of the second exhaust passage 4a, thereby realizing the effect of configuring the second exhaust passage 4a as a recessed structure. When the second adhesive barrier plate 4 comes into contact with the lateral beam 1b, the lateral beam 1b covers the open end of the second exhaust passage 4a, thereby forming the second exhaust passage 4a as a hollow structure, which prevents leakage as the gas flows through the second exhaust passage 4a.

[0059] In some embodiments of the present disclosure, the lateral beam 1b of the tray 1 has an exhaust structure, the exhaust structure is in communication with a first exhaust passage 2a and / or a second exhaust passage 4a. It will be understood that the exhaust structure is in communication with the first exhaust passage 2a, or the exhaust structure is in communication with the second exhaust passage 4a, or the exhaust structure is in communication with both the first exhaust passage 2a and the second exhaust passage 4a.

[0060] The exhaust structure may further be configured as an exhaust port or exhaust valve, with one end of the exhaust structure communicating with the first exhaust passage 2a and / or the second exhaust passage 4a, and the other end of the exhaust structure communicating with the external environment of the battery pack container, thereby achieving the effect of both the first exhaust passage 2a and the second exhaust passage 4a communicating with the external environment. As a result, if thermal runaway occurs in the battery cell 100, the gas discharged from inside the battery cell 100 can be discharged from the battery pack through the exhaust structure, thereby improving the safety of the battery pack during use and reducing the risk of battery pack failure.

[0061] This disclosure further describes, as one embodiment, that the first exhaust passage 2a is in communication with the second exhaust passage 4a, and the second exhaust passage 4a is in communication with the exhaust structure. This achieves the effect of both the first exhaust passage 2a and the second exhaust passage 4a being in communication with the exhaust structure. Therefore, in the event of thermal runaway in the battery cell 100, the gas inside the battery cell 100 flows from the exhaust port 2b into the first exhaust passage 2a, flows along the first exhaust passage 2a into the second exhaust passage 4a, and the gas is discharged from the battery pack container through the exhaust structure. This allows the gas inside the battery cell 100 to be released quickly, thereby reducing the internal pressure of the battery cell 100 and reducing the risk of battery pack failure.

[0062] In some embodiments of the present disclosure, as shown in Figure 8, a communication passage 2c may be further formed in the mounting bracket 2, configuring a plurality of first exhaust passages 2a, the communication passage 2c being connected between two adjacent first exhaust passages 2a so as to enable communication between the two adjacent first exhaust passages 2a, so that if one of the two adjacent first exhaust passages 2a is blocked, the gas in the blocked first exhaust passage 2a flows along the communication passage 2c to the other first exhaust passage 2a, ensuring the exhaust effect of the first exhaust passages 2a, reducing the risk of insufficient exhaust, and allowing the gas inside the battery cell 100 to be released quickly, thereby reducing the internal pressure of the battery cell 100 and reducing the risk of explosion of the battery cell 100.

[0063] Furthermore, multiple communication passages 2c are connected between two adjacent first exhaust passages 2a, and each of the multiple communication passages 2c is in communication with two adjacent first exhaust passages 2a. Therefore, if one of the multiple communication passages 2c is blocked, gas can flow between the two adjacent first exhaust passages 2a through the other communication passages 2c, ensuring communication between the two adjacent first exhaust passages 2a. This allows the gas inside the battery cell 100 to be released quickly, thereby reducing the internal pressure of the battery cell 100 and decreasing the risk of explosion.

[0064] In some embodiments of this disclosure, as shown in Figure 8, the first recess and the second recess are located on the lower surface of the bottom wall of the mounting bracket 2, and the first recess and the second recess are configured as the first exhaust passage 2a and the communication passage 2c, respectively.

[0065] Both the first and second recesses are further recessed in the thickness direction (i.e., vertical direction) of the mounting bracket 2 from the bottom wall of the mounting bracket 2 toward the inside of the mounting bracket 2, as shown in Figure 8, forming the first and second recesses on the lower surface of the bottom wall of the mounting bracket 2, thereby achieving the effect of forming the first exhaust passage 2a and the communication passage 2c in the bottom wall of the mounting bracket 2.

[0066] When the mounting bracket 2 is assembled into the housing cavity 10, the bottom plate 1a covers the open ends of the first exhaust passage 2a and the connecting passage 2c, thereby achieving the effect of forming a cavity structure in the first exhaust passage 2a and the connecting passage 2c, and enabling gas to flow through the first exhaust passage 2a and the connecting passage 2c.

[0067] In some embodiments of the present disclosure, as shown in Figures 8 and 12, the abutment portion 42 is located on the side of the second adhesive barrier plate 4 away from the first adhesive barrier plate 3, and the abutment portion 42 abuts against the lateral beam 1b and is located within the second exhaust passage 4a, which is beneficial because the second adhesive barrier plate 4 improves the structural strength and stability of the area provided with the second exhaust passage 4a, thereby ensuring that the second adhesive barrier plate 4 is securely attached to the mounting bracket 2.

[0068] Furthermore, as shown in Figure 12, the contact portion 42 is configured as a contact column, and when the second adhesive barrier plate 4 is placed in the housing cavity 10, one end of the contact portion 42 abuts against the lateral beam 1b in the longitudinal direction (i.e., front-to-back direction) of the battery pack container, and the other end of the contact portion 42 is connected to the surface of the second exhaust passage 4a facing the lateral beam 1b. The contact portion 42 is supported and positioned between the second adhesive barrier plate 4 and the lateral beam 1b, thereby improving the stability of the second adhesive barrier plate 4 and ensuring that the second adhesive barrier plate 4 is securely attached to the mounting bracket 2. Moreover, because the contact portion 42 is supported and positioned between the second adhesive barrier plate 4 and the lateral beam 1b, when the adhesive is filled into the adhesive filling area 5, the contact portion 42 can withstand the force applied to the second adhesive barrier plate 4 by the foamed adhesive in the longitudinal direction of the battery pack container, reducing the risk of deformation of the second adhesive barrier plate 4.

[0069] In some embodiments of the present disclosure, as shown in Figures 8 and 12, a reinforcing structure 43 is further formed on the side of the second adhesive barrier plate 4 away from the first adhesive barrier plate 3, comprising a plurality of contact portions 42, at least one of which is connected to the reinforcing structure 43.

[0070] The reinforcing structure 43 may also be configured as a reinforcing rib, as shown in Figures 8 and 12. The reinforcing structure 43 is positioned on the side of the second adhesive barrier plate 4 facing the lateral beam 1b, which is beneficial as it improves the structural strength of the second adhesive barrier plate 4. As a result, when the adhesive is filled into the adhesive filling area 5, the second adhesive barrier plate 4 can withstand the force applied to it by the foamed adhesive in the longitudinal direction of the battery pack container, reducing the risk of deformation of the second adhesive barrier plate 4. The abutment portion 42 is further connected to the reinforcing structure 43, which is beneficial as it improves the connection strength between the abutment portion 42 and the second adhesive barrier plate 4, reduces the risk of deformation of the abutment portion 42, and thus ensures that the abutment portion 42 is securely supported between the second adhesive barrier plate 4 and the lateral beam 1b.

[0071] As shown in Figures 8 and 12, in some embodiments of the present disclosure, for example, the reinforcing structure 43 is located within the second exhaust passage 4a and connected to the abutment portion 42, thereby improving the stability of the abutment portion 42 and the structural strength of the second exhaust passage 4a in the second adhesive barrier plate 4.

[0072] According to the battery pack of the embodiment of the present disclosure, the battery pack includes a plurality of battery cells 100 and a battery pack container according to the embodiment described above, wherein the plurality of battery cells 100 are attached to a mounting bracket 2, and a plurality of explosion-proof parts of the battery cells 100 correspond one-to-one with a plurality of exhaust ports. If thermal runaway occurs in the battery cell 100, it is ensured that the exhaust port 2b can avoid the explosion-proof part, which is normally open, and the gas discharged from inside the battery cell 100 flows from the exhaust port 2b into the first exhaust passage 2a, and the gas flows along the first exhaust passage 2a, so that the gas inside the battery cell 100 is quickly discharged, which is beneficial because it reduces the internal pressure of the battery cell 100 and further reduces the risk of explosion of the battery cell 100.

[0073] In some embodiments of this disclosure, the battery cell 100 is a cylindrical battery, as shown in Figure 1.
