Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a CCS bracket, battery pack and electrical equipment. Background Technology

[0002] As a crucial energy source for electronic devices, the performance and safety of batteries are critical to product design and use. In recent years, the rapid development of portable devices, electric vehicles, and energy storage systems has led to increasing demands for battery energy density, consequently driving the widespread application of high-energy-density battery technology. However, this increased energy density also brings higher requirements for thermal management and safety protection.

[0003] In related technologies, once a battery experiences thermal runaway during operation, it often releases a large amount of heat in a very short time, accompanied by the ejection of electrolyte and fumes. The ejected electrolyte or fumes may directly enter the battery pack, thereby adversely affecting adjacent cells or module wiring harnesses, posing a certain safety hazard. Utility Model Content

[0004] This application provides a CCS bracket, a battery pack, and an electrical device that can prevent electrolyte or flue gas from directly entering the battery, thereby at least partially solving the above-mentioned technical problems.

[0005] To achieve the above objectives, according to a first aspect of this application, a CCS support is provided, comprising: The frame has explosion-proof holes configured to align with the explosion-proof valves of the battery cells; and A flip cover, movably mounted on the frame, is used to close the explosion-proof hole; The flip cover is configured to open when the battery cell experiences thermal runaway and ejects waste, so that the waste is discharged through the explosion-proof hole.

[0006] By adopting the above technical solution, the flip cover can be pushed open when a battery cell experiences thermal runaway and ejects waste, thus providing a discharge path for the waste and releasing the pressure inside the thermally runaway cell. Meanwhile, the flip cover for cells not in a thermal runaway state remains closed, preventing the waste from spreading into adjacent cells. This helps prevent waste from entering adjacent cells, thereby mitigating the risk of adjacent cells being affected by waste ejected from the thermally runaway cell and ultimately improving the overall operational safety of the battery.

[0007] In some embodiments, the flip cover has a first state and a second state, wherein when the flip cover is in the first state, the explosion-proof hole is closed, and when the flip cover is in the second state, the explosion-proof hole is open; The flip cover is configured to switch from the first state to the second state under the action of the venting material from the thermally runaway battery cell when the battery cell experiences thermal runaway.

[0008] By adopting the above technical solution, the flip cover can switch from a closed state to an open state under the action of the discharge from the thermally runaway battery cell, thereby opening the explosion-proof vent when needed, while keeping it closed under normal operating conditions. In this way, the flip cover can be opened without relying on an additional triggering mechanism, the structure is relatively simplified, it is beneficial to improve the timeliness of the discharge response, and it is suitable for reducing the failure risk that additional mechanisms may bring.

[0009] In some embodiments, the flip cover is hinged to the frame.

[0010] By adopting the above technical solution, the flip cover is mounted on the frame in a hinged manner, allowing it to rotate around the hinge position, thereby enabling the opening and closing of the explosion-proof vent. This structure facilitates the stable positioning of the flip cover and also allows it to open smoothly when subjected to the force of released materials, thus improving the reliability of the explosion-proof vent's opening and closing.

[0011] In some embodiments, the radial dimension of the explosion-proof hole is not smaller than that of the explosion-proof valve.

[0012] By adopting the above technical solution, the radial dimension of the explosion-proof orifice is not less than the dimension of the explosion-proof valve, ensuring that when the explosion-proof valve of the battery cell opens and discharges the discharged material, the discharged material can be smoothly discharged through the explosion-proof orifice. This structure helps to reduce the obstruction effect of the discharged material when passing through the explosion-proof orifice, thereby improving the smoothness of the pressure relief process.

[0013] In some embodiments, the frame has a wiring channel, and the outlet of the explosion-proof hole is located outside the wiring channel.

[0014] By adopting the above technical solution, the wiring channel is used to accommodate the wire harnesses inside the battery pack, protecting the wire harnesses within the internal space of the frame, while the outlet of the explosion-proof hole is located outside the wiring channel. When a battery cell experiences thermal runaway and ejects effluent, the effluent is guided to the outside of the wiring channel for discharge, avoiding direct contact between the effluent and the wire harnesses inside the wiring channel, thereby reducing the risk of damage to the wire harnesses.

[0015] In some embodiments, the frame is provided with a cable pass-through port communicating with the wiring channel.

[0016] By adopting the above technical solution, the cable entry port is connected to the wiring channel, allowing the wire harnesses inside the battery pack to be introduced into the wiring channel through the cable entry port. In this way, the wire harnesses are centrally deployed within the wiring channel, which facilitates the orderly management of the wire harnesses and also makes it easier for the wire harnesses within the wiring channel to connect with conductive components such as aluminum busbars.

[0017] In some embodiments, the frame includes a base plate and a cover plate, and the wiring channel is formed by the base plate and the cover plate.

[0018] By adopting the above technical solution, the wire harness can be laid out in a relatively enclosed space, providing a certain degree of protection and reducing the impact of the external environment on the wire harness. At the same time, this structure facilitates the formation and installation of wiring channels and enables centralized management of the wire harness.

[0019] In some embodiments, the cover plate is detachably mounted on the base plate.

[0020] By adopting the above technical solution, when laying wire harnesses in the wiring channel, the operating space can be obtained by removing the cover plate, thus facilitating the installation and arrangement of wire harnesses. At the same time, when it is necessary to maintain or replace the wire harnesses in the wiring channel, the operation can also be achieved by removing the cover plate, thereby improving the convenience of wire harness installation and maintenance.

[0021] In some embodiments, the base plate is provided with mounting holes, and the cable passage of the frame is oriented toward the mounting holes.

[0022] By adopting the above technical solution, the mounting holes on the base plate facilitate the installation of components such as aluminum busbars inside the battery pack, and the wire passage is set to face the mounting holes, so that the wire harness in the wiring channel can smoothly extend to the aluminum busbar position through the wire passage, thereby facilitating the electrical connection between the wire harness and the aluminum busbar.

[0023] In some embodiments, the base plate is provided with a partition that protrudes from the base plate, and the base plate, the partition, and the cover plate together form the wiring channel.

[0024] By adopting the above technical solution, the protruding partition on the base plate cooperates with the cover plate to enclose the wiring channel to form a relatively closed space, so that the wire harness is fixed and protected in the channel. This helps to prevent the wire harness from shifting or making improper contact during battery pack vibration or transportation, and at the same time facilitates the orderly management of wiring.

[0025] In some embodiments, the cable passage of the frame is located in the partition.

[0026] By adopting the above technical solution, the wire passage is set at the position of the partition, so that the wire passage can be formed during the partition forming process, which helps to simplify the production process and improves the convenience of connecting the wiring channel to external conductive components.

[0027] In some embodiments, the frame further includes a stop bar that extends at least partially into the wiring channel to prevent wire harnesses within the wiring channel from detaching from the wiring channel.

[0028] By adopting the above technical solution, the baffle is used to restrict the wire harness and prevent it from coming out of the wiring channel.

[0029] In some embodiments, the baffle is disposed on the partition.

[0030] By adopting the above technical solution, baffles can be formed simultaneously during the partition forming process, which helps to simplify the manufacturing process and is suitable for reducing production costs.

[0031] In some embodiments, the baffle is disposed on the side of the partition away from the bottom plate.

[0032] By adopting the above technical solution, a larger space is formed between the baffle and the base plate, which not only restricts the wire harness but also provides relatively sufficient space for the wire harness to be arranged. This helps to reduce the squeezing or interference of the wire harness in the wiring channel, and thus improves the stability and reliability of the wiring.

[0033] In some embodiments, the height of the baffle away from the bottom plate is the same as the height of the partition protruding from the bottom plate.

[0034] By adopting the above technical solution, after the cover plate is installed, the baffle and partition can provide relatively stable support for the cover plate, which helps to maintain the positioning stability of the cover plate and is suitable for improving the overall structural reliability of the wiring channel.

[0035] In some embodiments, the explosion-proof hole is located inside the wiring channel, and a barrier is provided around the explosion-proof hole. The barrier protrudes from the bottom plate of the frame and is configured to guide the vents ejected during thermal runaway of the battery cell to the outside of the wiring channel.

[0036] By adopting the above technical solutions, it is beneficial to achieve a reasonable layout of explosion-proof holes and wiring channels, making the overall structure more compact, reducing the space occupied, and thus making it suitable for reducing the size of the battery pack.

[0037] In some embodiments, the cover plate is provided with a discharge hole, and the enclosure extends through the discharge hole to the outside of the wiring channel, so that the vents ejected during thermal runaway of the battery cell are discharged to the outside of the wiring channel.

[0038] By adopting the above technical solution, the discharge hole on the cover plate, together with the extension of the enclosure, allows the discharge material ejected during thermal runaway of the battery cell to be discharged outside the wiring channel along a predetermined path, thereby reducing the impact of the discharge material on the wiring harness inside the wiring channel, which is beneficial to protecting the integrity of the wiring harness and is suitable for improving the safety of the battery pack.

[0039] In some embodiments, the flap is located on the enclosure or the cover plate.

[0040] By adopting the above technical solution, the flip cover can be flexibly opened according to the effect of the released material when the battery cell experiences thermal runaway, thereby guiding the released material of the thermal runaway battery cell while keeping the explosion-proof holes of the battery cells that have not experienced thermal runaway in a closed state, which is conducive to improving the overall safety of the battery pack.

[0041] In some embodiments, reinforcing ribs are provided between the enclosure and the base plate.

[0042] By adopting the above technical solution, reinforcing ribs are set between the enclosure and the base plate, which enhances the structural strength of the frame and improves its resistance to deformation, thereby helping to maintain the stability of the wiring channel and explosion-proof hole structure.

[0043] In some embodiments, the partition and the reinforcing rib protrude from the base plate at the same height.

[0044] By adopting the above technical solution, the partition and the reinforcing rib protrude from the bottom plate at the same height, so that the partition and the reinforcing rib can provide relatively stable support for the cover plate after the cover plate is installed, thereby improving the installation stability of the cover plate and the reliability of the entire wiring channel structure.

[0045] In some embodiments, there are multiple explosion-proof holes, and the enclosures between adjacent explosion-proof holes are connected by the reinforcing ribs.

[0046] By adopting the above technical solution, the enclosures between the explosion-proof holes are connected by reinforcing ribs, which enhances the structural strength of the frame and improves its resistance to deformation. This helps to maintain the stability of the wiring channel and the explosion-proof hole structure. At the same time, this structure helps to form a partitioned space within the wiring channel, which facilitates the classification, arrangement and management of wire harnesses.

[0047] In some embodiments, the partition has a first contact surface on the side facing away from the base plate, the reinforcing rib has a second contact surface on the side facing away from the base plate, the frame's baffle has a third contact surface on the side facing away from the base plate, and the cover plate is in contact with at least two of the first contact surface, the second contact surface, and the third contact surface.

[0048] By adopting the above technical solution, the cover plate can obtain relatively stable support after installation through the first bonding surface, the second bonding surface and the third bonding surface, thereby improving the positioning stability of the cover plate and the overall reliability of the wiring channel structure.

[0049] According to a second aspect of this application, a battery is provided, including the CCS bracket described in the above-described technical solution.

[0050] According to a third aspect of this application, an electrical device is also provided, including the CCS bracket described in the above technical solution, or including the battery described in the above technical solution.

[0051] In the CCS support of this application embodiment, by providing a flip cover on the support body, the flip cover can be pushed open when a cell experiences thermal runaway and ejects discharge material, thereby providing a discharge path for the discharge material and releasing the internal pressure of the thermally runaway cell. Meanwhile, the flip covers corresponding to cells that have not experienced thermal runaway remain closed, thus preventing the discharge material from spreading to adjacent cells. This reduces the risk of adjacent cells being affected by the discharge material from the thermally runaway cell, and improves the overall safety of battery operation.

[0052] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0058] According to the first aspect of this application, referring to Figures 1 to 4 This disclosure provides a CCS bracket for use in a battery pack. Exemplarily, the battery pack contains multiple battery cells 10, each equipped with an explosion-proof valve so that, in the event of thermal runaway, any venting material within the battery cell 10 can be ejected through the explosion-proof valve. The venting material may include high-temperature fumes or electrolyte, etc.

[0059] The CCS support includes a frame 100 and a flip cover 200. The frame 100 has explosion-proof holes 110, which are configured to align with the explosion-proof valves of the battery cell 10. For example, each explosion-proof valve corresponds to one explosion-proof hole 110, so that in the event of thermal runaway of the battery cell 10, the discharged material ejected from the battery cell 10 can be smoothly discharged through the explosion-proof holes 110. With this structure, in the event of thermal runaway, the explosion-proof holes 110 provide a relatively unobstructed discharge path, allowing the internal pressure of the battery cell 10 to be released, thereby helping to reduce the impact of thermal runaway on the battery cell 10 and adjacent battery cells 10.

[0060] It should be understood that the so-called "explosion-proof hole 110" refers to the opening on the frame 100 used to guide the discharge of ejected material in the event of thermal runaway of the battery cell 10. Its radial dimension can be the same as or slightly larger than that of the corresponding explosion-proof valve so that the discharged material can pass through smoothly without obstruction.

[0061] In some embodiments, refer to Figure 1 and Figure 4 The flip cover 200 is movably mounted on the frame 100 and is used to close the explosion-proof hole 110. The flip cover 200 is configured to open when the battery cell 10 experiences thermal runaway and ejects vented material, so that the vented material can be discharged through the explosion-proof hole 110.

[0062] The "flip cover 200 active setting" refers to the flip cover 200 being able to flip or move around the hinge point or through other active means, so that it can be active and open when the battery cell 10 experiences thermal runaway, and remain closed in the non-thermal runaway state, thereby preventing the leakage of material from spreading to adjacent battery cells 10.

[0063] For example, the flip cover 200 can be flipped or moved around the hinge point or through other means, so that when the cell 10 experiences thermal runaway and ejects discharge material, it is pushed open by the discharge material, allowing the discharge material to be discharged through the explosion-proof hole 110. This allows the pressure inside the thermally runaway cell 10 to be released, while the flip covers 200 corresponding to cells 10 that have not experienced thermal runaway remain closed, which helps to prevent the discharge material from spreading to adjacent cells 10, thereby reducing the impact on other cells 10 inside the battery pack and improving the overall operational safety of the battery pack.

[0064] In some embodiments, refer to Figure 1 and Figure 4 The flip cover 200 has a first state and a second state. When the flip cover 200 is in the first state, the explosion-proof hole 110 is closed. When the flip cover 200 is in the second state, the explosion-proof hole 110 is opened. The flip cover 200 is configured to switch from the first state to the second state under the action of the venting material of the thermally runaway battery cell 10 when thermal runaway occurs.

[0065] For example, the flip cover 200 can be rotatably connected or hinged around the explosion-proof hole 110. In the first state, the flip cover 200 covers the explosion-proof hole 110, keeping the explosion-proof hole 110 closed. When vented material is ejected from the explosion-proof hole 110, the force of the vented material can push the flip cover 200 to overcome its own weight or elastic resistance, causing the flip cover 200 to move or rotate, thereby opening it from the explosion-proof hole 110 and entering the second state, allowing the explosion-proof hole 110 to open and the vented material to be discharged smoothly through the explosion-proof hole 110. With the above structural configuration, the flip cover 200 can be passively opened when the battery cell 10 experiences thermal runaway, and remains covered when the battery cell 10 does not experience thermal runaway. This is beneficial in limiting the discharge direction of the vented material to a certain extent, while also being simple in structure and easy to manufacture and install.

[0066] In some embodiments, the flip cover 200 is hinged to the frame 100. Exemplarily, a pivot can be provided on the frame 100, and the flip cover 200 is rotatably connected to the frame 100 via the pivot, thereby enabling it to rotate about the pivot. When the flip cover 200 is in the first state, it covers the explosion-proof hole 110, keeping the explosion-proof hole 110 closed. When the battery cell 10 experiences thermal runaway and generates discharge, the discharge can push the flip cover 200 to rotate about the pivot, causing the flip cover 200 to open from the explosion-proof hole 110 into the second state, thereby opening the explosion-proof hole 110 and allowing the discharge to be smoothly discharged.

[0067] In some embodiments, the radial dimension of the explosion-proof orifice 110 is not smaller than that of the explosion-proof valve. Exemplarily, the radial dimension of the explosion-proof orifice 110 can be the same as or slightly larger than that of the explosion-proof valve, so that the vent material ejected from the explosion-proof valve can be smoothly discharged through the explosion-proof orifice 110. With an appropriately set radial dimension of the explosion-proof orifice 110, when the battery cell 10 experiences thermal runaway and ejects high-temperature fumes or liquids, the vent material can be discharged relatively smoothly through the explosion-proof orifice 110 without being blocked due to an excessively small orifice diameter. This helps reduce the instantaneous accumulation of internal pressure within the battery cell 10, while also maintaining the controllability of the vent material discharge direction to a certain extent.

[0068] In some embodiments, refer to Figure 2 and Figure 3 The frame 100 has a wiring channel 120, and the outlet of the explosion-proof hole 110 is located outside the wiring channel 120. Exemplarily, the wiring channel 120 can be formed as an integral part of the frame 100, or it can be assembled from multiple components to enclose and form the wiring channel 120. By providing the wiring channel 120, the wiring harness within the battery pack can be guided and protected within the wiring channel 120. When the battery cell 10 experiences thermal runaway, the discharged material is discharged through the explosion-proof hole 110 without directly contacting the wiring harness within the wiring channel 120, thereby reducing the potential impact of the discharged material on the wiring harness to a certain extent and helping to maintain the integrity of the wiring harness within the wiring channel 120 and the safety of the battery pack.

[0069] In some embodiments, refer to Figure 2 and Figure 3 The frame 100 is provided with a cable passage 130 communicating with the wiring channel 120. Exemplarily, the cable passage 130 can be located on the side wall of the wiring channel 120, forming an opening communicating with the wiring channel 120, allowing external wiring harnesses of the battery pack to extend into the wiring channel 120 through the cable passage 130 and connect with the wiring harnesses within the wiring channel 120. By providing the cable passage 130, the layout and classification of wiring harnesses within the wiring channel 120 can be facilitated, promoting orderly wiring management. It also facilitates the connection of wiring harnesses to external electrical components (such as aluminum busbars or busbars), thereby improving the overall wiring flexibility and maintainability of the battery pack.

[0070] In some embodiments, refer to Figure 1 and Figure 3The frame 100 includes a base plate 140 and a cover plate 150, and the wiring channel 120 is formed by the base plate 140 and the cover plate 150. Exemplarily, the cover plate 150 can be detachably mounted on the base plate 140 or integrally welded to the base plate 140. During the manufacturing or assembly of the battery pack, the wiring harness can be arranged or introduced into the wiring channel 120 through the opening or detached state of the cover plate 150. After the wiring harness is installed, the cover plate 150 is then fixed or installed in place, thereby protecting the wiring harness within the wiring channel 120. With this structure, the wiring channel 120 can protect the wiring harness from external interference, while facilitating the installation, organization, and maintenance of the wiring harness, improving the orderliness of the wiring and the safety of the battery pack.

[0071] It should be understood that the base plate 140 and the cover plate 150 may be made of insulating materials, such as plastic. By using insulating materials, the wiring channel 120 can reduce the electrical interference that may occur between the wiring harness and the frame 100, which is beneficial to improving the electrical safety inside the battery pack, while preventing the wiring harness from being worn or damaged by contact with metal parts within the wiring channel 120.

[0072] In some embodiments, the cover plate 150 is detachably disposed on the base plate 140. Exemplarily, the cover plate 150 can be connected to the base plate 140 by bolts, screws, or clips, enabling detachable installation. With this structure, during the wiring harness arrangement or maintenance of the battery pack, the cover plate 150 can be quickly opened or removed to allow the wiring harness to be arranged within the wiring channel 120. After installation or maintenance, the cover plate 150 can be reset or fixed, thereby protecting the wiring harness within the wiring channel 120 to a certain extent, while also facilitating the management and maintenance of the wiring harness.

[0073] In some embodiments, refer to Figure 3 and Figure 4 The base plate 140 is provided with mounting holes 141, and the cable passage 130 of the frame 100 faces the mounting holes 141. It should be understood that the battery pack typically contains aluminum busbars or similar conductive components. The mounting holes 141 allow the aluminum busbars to be exposed from the base plate 140. During battery pack assembly or operation, the module temperature and pressure harnesses within the wiring channel 120 need to connect to the corresponding interfaces on the aluminum busbars. By aligning the cable passage 130 with the mounting holes 141, the module temperature and pressure harnesses can smoothly extend from the wiring channel 120 to the aluminum busbars, facilitating connection and wiring operations, while maintaining, to a certain extent, the orderliness and safety of the wiring.

[0074] In some embodiments, refer to Figure 3 and Figure 4The base plate 140 is provided with a partition 142, which protrudes from the base plate 140. The base plate 140, the partition 142, and the cover plate 150 together form a wiring channel 120. For example, the partition 142 can be integrally provided with the base plate 140, and both the partition 142 and the base plate 140 can be made of plastic. The partition 142 and the base plate 140 are formed by integral injection molding, thereby reducing production costs and facilitating the structural stability of the wiring channel 120 and the arrangement of wire harnesses.

[0075] For example, the partitions 142 can be arranged opposite each other, forming two sides of the wiring channel 120, with the bottom plate 140 located on the bottom side of the opposite partitions 142 and the cover plate 150 located on the top side of the opposite partitions 142, thereby enclosing and forming a closed wiring channel 120.

[0076] In some embodiments, the wire passage 130 of the frame 100 is provided on the partition 142. Exemplarily, the wire passage 130 can be set as a notch on the partition 142. By forming the wire passage 130 on the partition 142, the partition 142 can be divided into several segments, thereby reducing the risk of deformation that may be caused by the excessive extension of the partition 142 to a certain extent. At the same time, it is convenient to directly form the wire passage 130 during the forming process of the partition 142, so as to realize the integration of structure and function.

[0077] In some embodiments, refer to Figure 3 and Figure 4 The frame 100 also includes a retaining strip 160, which at least partially extends into the wiring channel 120 to prevent the wire harness within the wiring channel 120 from detaching from the wiring channel 120. Exemplarily, the retaining strip 160 may be disposed on the base plate 140 and / or the partition 142. By forming the retaining strip 160 within the wiring channel 120, a certain degree of constraint can be provided on the wire harness before the wiring channel 120 is covered by the cover plate 150, keeping the wire harness within the wiring channel 120, thereby facilitating the subsequent installation of the cover plate 150 and the securing of the wire harness.

[0078] In some embodiments, a baffle 160 is disposed on a partition 142. Exemplarily, the baffle 160 may be integrally formed with the partition 142 and extend along the width direction of the wiring channel 120, thereby constraining the wire harness within the wiring channel 120. Multiple baffles 160 may be provided, spaced apart along the length direction of the wiring channel 120. The baffles 160 may be distributed on the partitions 142 on both sides of the wiring channel 120, i.e., the baffle 160 may extend from one partition 142 towards the other side of the wiring channel 120, or from the other partition 142 towards one side of the wiring channel 120, to maintain the stable position of the wire harness before the cover plate 150 is installed.

[0079] In some embodiments, refer to Figure 3 and Figure 4 The baffle 160 is disposed on the side of the partition 142 away from the base plate 140. This creates a larger space between the baffle 160 and the base plate 140, thereby restricting the wire harness while providing relatively sufficient space for its arrangement. This helps to reduce the compression or interference of the wire harness in the wiring channel 120, and thus improves the stability and reliability of the wiring.

[0080] In some embodiments, the height of the side of the baffle 160 facing away from the base plate 140 is the same as the height of the partition 142 protruding from the base plate 140. Exemplarily, the side of the baffle 160 facing away from the base plate 140 is approximately flush with the side of the partition 142 facing away from the base plate 140. When the cover plate 150 is installed, it can simultaneously contact the baffle 160 and the partition 142, thereby providing support for the cover plate 150 and making it more stable after installation.

[0081] In some embodiments, the explosion-proof hole 110 is located within the wiring channel 120, and a barrier 170 is provided around the explosion-proof hole 110. The barrier 170 protrudes from the base plate 140 of the frame 100 and is configured to guide the discharge material ejected from the cell 10 during thermal runaway to the outside of the wiring channel 120. Through the barrier 170, a dedicated channel for discharge material can be formed within the wiring channel 120, allowing the discharge material from the thermally runaway cell 10 to be discharged smoothly without additionally occupying internal space of the battery pack. This structure contributes to a more compact overall layout and helps reduce the size of the battery pack.

[0082] In some embodiments, refer to Figure 2 and Figure 4 The cover plate 150 is provided with a discharge hole 151, and the enclosure 170 extends through the discharge hole 151 to the outside of the wiring channel 120, so that the discharge material ejected in the event of thermal runaway of the battery cell 10 can be discharged to the outside of the wiring channel 120. Through the combination of the discharge hole 151 and the enclosure 170, a clear drainage path can be formed inside the wiring channel 120, so that the discharge material does not remain in the channel, and at the same time, it helps to maintain the integrity of the wiring harness and other components inside the wiring channel 120.

[0083] In some embodiments, the flip cover 200 is movably disposed on the enclosure 170 or the cover plate 150. Exemplarily, the flip cover 200 is movably disposed on the enclosure 170 and located at the end of the enclosure 170 opposite to the explosion-proof hole 110. Thus, when the battery cell 10 experiences thermal runaway and ejects waste material, the waste material contacts the flip cover 200 after passing through the enclosure 170 for a certain distance, potentially increasing the force exerted on the flip cover 200 and making it easier for the flip cover 200 to switch from the first state to the second state. Simultaneously, the enclosure 170 has a guiding effect on the ejected waste material, which helps to concentrate the waste material and limit its ejection path, thereby reducing the impact on the wiring harness or other components within the wiring channel 120.

[0084] In some embodiments, refer to Figure 3 and Figure 4 A reinforcing rib 180 is provided between the enclosure 170 and the base plate 140. For example, the reinforcing rib 180 is connected to the enclosure 170 and the base plate 140 respectively. On the one hand, it can enhance the connection reliability between the enclosure 170 and the base plate 140. On the other hand, it can provide additional support for the frame 100 as a whole, thereby improving the structural strength of the frame 100 and its resistance to deformation to a certain extent.

[0085] In some embodiments, the partition 142 and the reinforcing rib 180 protrude from the base plate 140 at the same height. Exemplarily, the side of the partition 142 facing away from the base plate 140 and the side of the reinforcing rib 180 facing away from the base plate 140 are at the same horizontal position. When the cover plate 150 is installed, the cover plate 150 can simultaneously contact the partition 142 and the reinforcing rib 180, thereby improving the load-bearing support effect of the cover plate 150 and making the stability of the cover plate 150 better after installation.

[0086] In some embodiments, there are multiple explosion-proof holes 110, and the enclosures 170 between adjacent explosion-proof holes 110 are connected by reinforcing ribs 180. Exemplarily, the reinforcing ribs 180 are disposed between two adjacent enclosures 170 and are fixedly connected to the base plate 140, thereby enhancing the overall structural strength of the enclosures 170 and the base plate 140 while connecting adjacent enclosures 170.

[0087] In some embodiments, refer to Figure 3 and Figure 4 The partition 142 has a first contact surface 142a on the side facing away from the base plate 140, the reinforcing rib 180 has a second contact surface 181 on the side facing away from the base plate 140, and the baffle 160 of the frame 100 has a third contact surface 161 on the side facing away from the base plate 140. The cover plate 150 is in contact with at least two of the first contact surface 142a, the second contact surface 181, and the third contact surface 161. Exemplarily, the cover plate 150 is simultaneously in contact with the first contact surface 142a, the second contact surface 181, and the third contact surface 161 so that after installation, the partition 142, the reinforcing rib 180, and the baffle 160 together provide support for the cover plate 150, thereby enhancing the stability of the cover plate 150.

[0090] The electrical device can be an electric vehicle, an electric bicycle, an electric motorcycle, an energy storage station, a power tool, or other electronic product that requires the use of a battery module. For example, when the electrical device is an electric vehicle, the CCS bracket can be used to fix the battery module and guide the discharge of the leakage in the event of thermal runaway of the battery cell 10, thereby helping to improve the safety of the battery pack under extreme operating conditions.
