[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0024] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there can also be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

[0025] Unless otherwise defined, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the present utility model in the specification are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used in the present utility model includes any and all combinations of one or more of the related listed items.

[0026] Next, in conjunction with the accompanying drawings, some embodiments of the present utility model will be described in detail. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0027] In the prior art, a cross beam is required for exhaust, and a certain assembly gap must be reserved between the battery cell module and the cross beam, that is, there is still a certain distance between the explosion-proof valve of the battery cell and the exhaust hole of the cross beam. The high-temperature gas and electrolyte after the out-of-control battery cell opens the valve may flow to other battery cells in the same module, causing thermal diffusion.

[0028] Reference Figures 1 to 3 , the present utility model provides an exhaust member 6 for the tray 1. The exhaust member 6 is a strip-shaped hollow member. The exhaust member 6 is clamped between the two side beams of the tray 1 or between the side beam and the cross beam. Both ends of the exhaust member 6 are respectively communicated with the exhaust cavities of the side beams. At least one side of the exhaust member 6 is provided with a one-way valve 7. The opening of the one-way valve 7 is arranged corresponding to the opening of the explosion-proof valve 4 of the battery cell 5 of the battery cell module. The number of one-way valves 7 is arranged corresponding to the number of battery cells 5 of the battery cell module. The one-way valve 7 is used to open and communicate to discharge the mixture when the explosion-proof valve 4 of the battery cell 5 opens, and closes and disconnects after discharging the mixture.

[0029] Specifically, the above innovative exhaust member 6 is designed specifically for the tray 1 to ensure the safety during the storage and transportation of the battery. The exhaust member 6 adopts a strip-shaped hollow structure design, enabling it to be conveniently clamped between the two side beams of the tray 1 or between the side beam and the cross beam, forming a stable fixed structure. This design is not only easy to install, but also can be closely combined with the tray 1 to improve the stability of the overall structure.

[0030] The design of the exhaust component 6 specifically takes into account the safety requirements of the battery. At both ends of the exhaust component 6, it is respectively connected to the side beam exhaust cavity of the tray 1 to form an unobstructed exhaust passage. This design enables the mixture of high-pressure gas and electrolyte inside to be quickly and effectively discharged through the exhaust component 6 when the battery cell 5 in the battery cell module triggers the explosion-proof valve 4 due to overheating or other reasons, thus avoiding serious consequences such as explosion or rupture caused by excessive internal pressure.

[0031] More notably, the exhaust component 6 is provided with check valves 7 on at least one side. The openings of these check valves 7 correspond to the openings of the explosion-proof valves 4 of the battery cells 5 in the cell module, ensuring that when the explosion-proof valve 4 of the battery cell 5 is opened, the check valves 7 of the exhaust component 6 can quickly open and form a connection with the explosion-proof valve 4 of the battery cell 5, enabling the mixture to be discharged smoothly. After the exhaust is completed, the check valves 7 can automatically close, disconnecting the connection with the explosion-proof valve 4 of the battery cell 5, preventing external impurities or moisture from entering the battery interior and ensuring the safety of the battery's internal environment.

[0032] In addition, the number of check valves 7 is set according to the number of battery cells 5 in the cell module. This design can ensure that each battery cell 5 has a corresponding check valve 7 when the explosion-proof valve 4 is triggered, achieving an accurate and efficient exhaust effect. This not only improves the exhaust efficiency but also reduces the possible failure rate during the exhaust process, further ensuring the safety of the battery.

[0033] In summary, the exhaust component 6 of the present utility model has important application value in the design of the battery tray 1. Through its innovative structural design and function realization, it effectively improves the safety during the storage and transportation of the battery. At the same time, its easy installation, stable and reliable characteristics also make it widely applicable and convenient in practical applications.

[0034] In one embodiment, the check valve 7 includes a baffle 8 and a spring 9. The baffle 8 abuts against the explosion-proof valve 4 of the battery cell 5, and the spring 9 is arranged behind the baffle 8 for resetting the baffle 8.

[0035] Specifically, the check valve 7 in the exhaust component 6 is designed particularly exquisitely, ensuring its high efficiency and reliability in the safe exhaust of the battery. The check valve 7 mainly consists of two core components, namely a baffle 8 and a spring 9. The baffle 8 directly abuts against the explosion-proof valve 4 of the battery cell 5, forming a sealed interface. This design ensures that the baffle 8 can tightly seal the exhaust passage without triggering the explosion-proof valve 4 of the battery cell 5, preventing external impurities or moisture from entering the battery interior and ensuring the safety of the battery's internal environment.

[0036] As another important component of the one-way valve 7, the spring 9 is cleverly arranged behind the baffle 8. The main function of the spring 9 is to provide a reset force to ensure that the baffle 8 can be quickly and accurately reset and re-seal the exhaust channel after the explosion-proof valve 4 of the battery cell 5 is opened and the exhaust is completed. This design not only improves the response speed of the exhaust member 6, but also enhances its reliability and durability.

[0037] When the battery cell 5 triggers the explosion-proof valve 4 due to overheating or other reasons, the internal high-pressure gas and electrolyte mixture will push the baffle 8 to move toward the spring 9, thereby opening the exhaust channel. At this time, the spring 9 is compressed to a certain extent, providing a reserve force for the reset of the baffle 8. As the mixture is discharged, the internal pressure gradually decreases. When the pressure drops to a certain level, the reset force of the spring 9 will push the baffle 8 back to its original position and re-seal the exhaust channel. In this process, the one-way valve 7 demonstrates its precise and efficient exhaust capability, ensuring the safety of the battery in dangerous situations.

[0038] In addition, the design of the one-way valve 7 also has good reusability. Even if the explosion-proof valve 4 of the battery cell 5 is triggered multiple times, the baffle 8 and the spring 9 can still maintain their original functions and performances, providing a strong guarantee for the long-term safe use of the battery.

[0039] In summary, the one-way valve 7 in this embodiment is exquisitely designed and powerful, and can ensure high efficiency and reliability in the process of safe exhaust of the battery. At the same time, its good reusability also provides strong support for the long-term safe use of the battery.

[0040] In one embodiment, a partition 3 is disposed in the middle of the cavity of the exhaust member 6 , the partition 3 divides the cavity into two cavities, one-way valves 7 are disposed on both sides of the partition 3 , and springs 9 are disposed on both sides of the partition 3 .

[0041] Specifically, the design of the exhaust member 6 is further optimized, especially in its cavity structure. A partition 3 is cleverly arranged in the middle of the cavity of the exhaust member 6, and the partition 3 divides the cavity into two independent parts, achieving the effect of isolation and partitioning.

[0042] One-way valves 7 are respectively provided in the cavities on both sides of the partition 3. Each one-way valve 7 is composed of a baffle 8 and a spring 9, and each spring 9 is placed on the side of the corresponding partition 3. This design ensures that each one-way valve 7 can work independently without interfering with each other. When the explosion-proof valve 4 of the battery cell 5 is opened, the one-way valve 7 of the corresponding cavity will respond quickly, and the baffle 8 will open under the action of the internal pressure, allowing the mixture of high-pressure gas and electrolyte to pass through and be discharged. At this time, the spring 9 is compressed, storing the energy required for reset.

[0043] During the exhaust process, the two cavities work independently through their respective one-way valves 7. Even if the explosion-proof valve 4 of one of the battery cells 5 is triggered, it will not affect the normal exhaust of the other cavity. This design improves the flexibility and reliability of the exhaust component 6, ensuring the safety performance of the battery pack in case of emergency.

[0044] After the exhaust is completed and the internal pressure decreases, the restoring force of the spring 9 will push the baffle 8 back to its original position to reseal the exhaust passage. During this process, the baffles 8 of the two one-way valves 7 will reset independently, ensuring the complete closure of the exhaust passage and preventing the entry of external impurities or moisture.

[0045] In addition, this design has another advantage: through the cavity separation setting, more precise exhaust control can be achieved. Each cavity corresponds to a different battery cell module, enabling the exhaust of each module to be independently controlled, avoiding possible interference and misoperation.

[0046] In summary, the exhaust component 6 with the partition 3 and double one-way valve 7 design not only improves the safety performance of the battery pack but also achieves more precise exhaust control through the cavity separation setting, providing a strong guarantee for the long-term stable operation of the battery pack.

[0047] In one embodiment, a card slot is provided on the side of the exhaust component 6 where the one-way valve 7 is not provided, and the card slot is used for the exhaust component 6 to be clamped on the tray 1.

[0048] Specifically, the design of the exhaust component 6 has been carefully considered to meet the actual requirements of the tray 1 exhaust system. In particular, a card slot is provided on the side of the exhaust component 6 where the one-way valve 7 is not provided. The function of this card slot is crucial. It ensures that the exhaust component 6 can be stably and accurately clamped on the tray 1, forming a tight and reliable connection.

[0049] The design of the card slot takes into account the structural characteristics of the tray 1, enabling the exhaust component 6 to be easily and quickly installed on the tray 1 without complex tools or cumbersome steps. This design not only improves the installation efficiency but also reduces the operation difficulty, making the installation and maintenance of the tray 1 exhaust system more convenient.

[0050] Through the tight connection between the card slot and the tray 1, the exhaust component 6 can better integrate into the entire battery storage system and form a whole with the tray 1. This integrated design enhances the stability and reliability of the system, reducing potential safety hazards caused by component loosening or detachment.

[0051] In addition, the design of the card slot also takes into account the sealing between the exhaust component 6 and the tray 1. Through the tight fit between the card slot and the tray 1, it can effectively prevent external impurities, moisture, etc. from entering the interior of the exhaust component 6, thus ensuring the normal operation of the exhaust component 6 and the safety of the battery.

[0052] In summary, the exhaust component 6 with the card slot design brings many advantages to the tray 1 exhaust system. It improves the installation efficiency, reduces the operation difficulty, enhances the stability and reliability of the system, and ensures good sealing between the exhaust component 6 and the tray 1. These advantages make this exhaust component 6 an indispensable part of the battery storage system, providing strong guarantee for the safe storage and transportation of batteries.

[0053] According to another embodiment of the present application, a tray 1 is provided, which includes a partition 3 and the above-mentioned exhaust component 6. The partition 3 is clamped between the two side beams or cross beams and side beams of the tray 1, and the exhaust component 6 is mounted on the partition 3 through a card slot.

[0054] Specifically, in the design of the above-mentioned new tray 1, the tray 1 cleverly combines the partition 3 and the above-mentioned exhaust component 6 to form a safe and efficient battery storage structure.

[0055] The partition 3 in the tray 1 is designed to be clamped between the two side beams or cross beams and side beams of the tray 1. This layout not only ensures the stability of the partition 3, but also strengthens the overall structural strength of the tray 1. The main function of the partition 3 is to divide the space of the tray 1 into multiple independent areas, and each area can independently place one or more battery cell modules, thereby realizing the separated storage of battery cell modules and reducing the risk of one battery cell module affecting other battery cell modules due to a failure.

[0056] More notably, the above-mentioned exhaust component 6 is equipped on the tray 1. The exhaust component 6 is stably mounted on the partition 3 through a carefully designed card slot. This design enables the exhaust component 6 to closely fit on the tray 1, not only ensuring the stability of the exhaust component 6, but also enhancing the overall airtightness of the tray 1. When the explosion-proof valve 4 of the battery cell module is triggered, the exhaust component 6 can quickly respond and safely discharge the mixture of high-pressure gas and electrolyte inside the battery cell module through the one-way valve 7 structure inside it, thereby avoiding the explosion or rupture of the battery cell module and ensuring the safety of the battery storage system.

[0057] The design of this new tray 1 has multiple advantages. First, the combination of the partition 3 and the exhaust component 6 enables the tray 1 to separate and store battery cell modules, improving the safety of the battery storage system. Second, the card slot mounting design of the exhaust component 6 makes installation and maintenance very simple, improving the usability of the tray 1. Finally, this design makes full use of the space of the tray 1, improving the capacity and efficiency of the battery storage system.

[0058] In summary, the design of the tray 1 in this embodiment realizes the separated storage and efficient exhaust of the battery storage system by combining the partition 3 and the exhaust component 6, providing a strong guarantee for the safe storage and transportation of the battery. This design not only improves the safety and reliability of the battery storage system but also meets the requirements of modern battery storage systems for efficiency and convenience.

[0059] In one embodiment, the tray 1 includes at least two cavities, and the partition 3 and the exhaust component 6 are disposed in the middle of the two cavities.

[0060] Specifically, the structure of the tray 1 has been optimized and innovated. The tray 1 includes at least two cavities, and in particular, the partition 3 and the exhaust component 6 are ingeniously disposed in the middle positions of the two cavities.

[0061] This design enables the tray 1 to be divided into two independent cavities, and each cavity can independently store the battery module or the battery cell 5, thus realizing the separated storage of the battery module or the battery cell 5. This separated storage method helps to reduce the potential risk to other modules or cells 5 caused by the failure of one battery module or cell 5, greatly enhancing the safety and reliability of the entire tray 1.

[0062] In the middle of the two cavities, the partition 3 plays a key isolation role. The partition 3 is strong and stable, ensuring the physical separation between the two cavities and also providing support for the upper battery module or battery cell 5. The design of the partition 3 not only enhances the overall structural strength of the tray 1 but also makes the tray 1 more uniform and stable when bearing the weight of the battery module or battery cell 5.

[0063] Above the partition 3 is the installation position of the exhaust component 6. The exhaust component 6 is firmly installed on the partition 3 through its unique slot design, forming a tight connection with the two cavities. A one-way valve 7 is provided inside the exhaust component 6. When the explosion-proof valve 4 of the battery module or battery cell 5 is triggered due to excessive internal pressure, the one-way valve 7 can quickly open, allowing the mixture of high-pressure gas and electrolyte to be safely discharged, while preventing external impurities and moisture from entering the battery interior. This design of the exhaust component 6 guarantees the safety performance of the battery module or battery cell 5 in case of emergency.

[0064] In summary, this design of disposing the partition 3 and the exhaust component 6 in the middle of the two cavities not only realizes the separated storage of the battery module or battery cell 5, improves the safety and reliability of the tray 1, but also provides an effective safety guarantee for the battery module or battery cell 5 through the setting of the exhaust component 6. This design enables the tray 1 to have a broader application prospect in the field of battery storage and transportation.

[0065] In one embodiment, an exhaust port 2 is provided at the connection between the side beam or cross beam of the tray 1 and the exhaust member 6, and the exhaust port 2 is used to connect the cavity of the exhaust member 6 with the side beam exhaust cavity.

[0066] Specifically, the structural details of the tray 1 reflect the ultimate pursuit of battery safety. Specifically, an exhaust port 2 is provided at the connection between the side beam or cross beam of the tray 1 and the exhaust member 6, and this design cleverly connects the cavity of the exhaust member 6 with the side beam exhaust cavity.

[0067] The realization of this connection mechanism lies first in the precise positioning of the exhaust port 2 on the side beam or cross beam. The exhaust port 2 is located at the key position where the side beam or cross beam of the tray 1 is connected to the exhaust member 6, ensuring a smooth connection between the two and unobstructed air flow transmission.

[0068] Secondly, the design of the exhaust port 2 not only considers structural convenience but also fully takes into account safety. Through the exhaust port 2, the cavity inside the exhaust member 6 can form a closed exhaust system with the side beam exhaust cavity. When the explosion-proof valve 4 is triggered due to excessive internal pressure in the battery cells 5 in the battery module, the high-pressure gas and electrolyte mixture inside the battery cells 5 can quickly enter the cavity of the exhaust member 6 through the one-way valve 7 inside the exhaust member 6, and then enter the side beam exhaust cavity through the exhaust port 2, and finally be discharged outside the tray 1.

[0069] The effect of this design is very remarkable. First of all, it ensures the safety performance of the battery module in case of emergency. Even if the battery cells 5 have abnormalities, the internal pressure can be quickly discharged through the exhaust system, avoiding serious consequences such as explosion or rupture caused by excessive internal pressure. Secondly, this design enhances the overall airtightness of the tray 1. The combined use of the exhaust port 2 and the exhaust member 6 enables the battery module inside the tray 1 to operate in a relatively closed environment, reducing the influence of external impurities or moisture on the battery module. Finally, this design also improves the maintainability of the tray 1. Due to the detachable design of the exhaust port 2 and the exhaust member 6, users can conveniently perform operations such as cleaning, maintenance, and replacement.

[0070] In summary, the exhaust port 2 provided at the connection between the side beam or cross beam of the tray 1 and the exhaust member 6 not only ensures the safety performance of the battery module in case of emergency but also enhances the overall airtightness and maintainability of the tray 1. This design reflects the high attention and careful consideration for battery safety, making the tray 1 have a broader application prospect in the field of battery storage and transportation.

[0071] According to another embodiment of the present application, a battery pack is provided, which includes an upper cover and the above-mentioned tray 1, and the upper cover is covered on the tray 1.

[0072] Specifically, the battery pack integrates the upper cover and the above-mentioned tray 1 structure, forming a safe, compact and efficient battery storage solution.

[0073] The upper cover of the battery pack is exquisitely designed and can perfectly cover the tray 1, forming a closed battery storage environment. This design not only protects the battery module from external environmental interference and damage, such as dust, moisture, vibration, etc., but also provides additional mechanical protection for the battery module, enhancing the structural strength and durability of the battery pack.

[0074] The design of the tray 1 is the core of the battery pack. As mentioned above, the tray 1 at least includes two cavities, and a partition 3 and an exhaust part 6 are arranged in the middle of the two cavities. The partition 3 divides the tray 1 into multiple independent storage areas, and each area can hold one or more battery modules, thus realizing the separated storage of battery modules and reducing the safety risk. The exhaust part 6 can quickly discharge high-pressure gas and electrolyte through the one-way valve 7 structure inside it when the pressure inside the battery module is abnormal, ensuring the safety of the battery module.

[0075] Combining such a tray 1 with the upper cover, the battery pack not only has excellent safety performance, but also has good maintainability and scalability. Users can simply open the upper cover to replace, repair or expand the battery modules in the tray 1. At the same time, due to the modular design of the tray 1, the battery pack can also be customized according to actual needs to meet the battery storage requirements in different application scenarios.

[0076] In addition, the overall structure of the battery pack is compact and lightweight, facilitating handling and installation. This enables the battery pack to have broad application prospects in fields such as electric vehicles and energy storage systems. Whether in the field of new energy vehicles or in the field of household energy storage, this kind of battery pack can provide a safe, reliable and efficient battery storage solution.

[0077] In summary, the battery pack in this embodiment realizes the safe storage, efficient exhaust and convenient maintenance of the battery module by integrating the upper cover and the tray 1 structure. This design not only improves the safety and reliability of the battery pack, but also enhances its maintainability and scalability, bringing an innovative solution to the battery storage field.

[0078] In one embodiment, the battery pack includes at least two sets of oppositely arranged battery cell modules, and the partition 3 and the exhaust part 6 are arranged in the middle of the two sets of battery cell modules.

[0079] Specifically, the above-mentioned new battery pack design includes at least two sets of oppositely arranged battery cell modules, and the partition 3 and the exhaust part 6 are cleverly arranged in the middle of the two sets of battery cell modules.

[0080] First, two sets of opposing battery cell modules are arranged inside the battery pack. This layout can greatly improve the energy density and power output capacity of the battery pack. Through reasonable layout and matching, the two sets of battery cell modules can work together to meet the energy requirements of the battery pack in various usage scenarios.

[0081] In the middle of the two sets of battery cell modules, a partition 3 is provided. The function of the partition 3 is not only to separate the two sets of battery cell modules to prevent the failure of one set of battery cell modules from affecting the other, but also to provide a solid support structure inside the battery pack, increasing the overall strength and stability of the battery pack. In addition, the partition 3 can be designed as needed, such as adding a thermal insulation layer or fireproof material, to improve the safety of the battery pack.

[0082] More importantly, an exhaust component 6 is also provided on the partition 3. The exhaust component 6 is one of the key components for the safety of the battery pack. It can quickly release pressure when the pressure inside the battery cell module is abnormal, preventing the battery cell module from exploding or rupturing. The design of the exhaust component 6 in the middle of the two sets of battery cell modules can ensure that when any battery cell module has an abnormality, the exhaust component 6 can exhaust gas in a timely and effective manner, ensuring the safety of the entire battery pack.

[0083] This design brings significant effects. First, through the relative arrangement of the two sets of battery cell modules, the battery pack can provide higher energy density and power output, meeting the requirements of more application scenarios. Second, the setting of the partition 3 effectively reduces the mutual influence between the battery cell modules, improving the safety and reliability of the battery pack. Finally, the design of the exhaust component 6 further enhances the safety of the battery pack, ensuring that pressure can be released in a timely manner when the battery cell module has an abnormality, preventing the battery pack from being in danger.

[0084] In summary, the design of the battery pack in this embodiment realizes a comprehensive improvement in aspects such as energy density, safety, and reliability of the battery pack through the relative arrangement of the two sets of battery cell modules, the separation of the partition 3, and the safety protection of the exhaust component 6, providing strong support for the application of the battery pack in fields such as electric vehicles and energy storage systems.

[0085] According to another embodiment of the present application, an electrical device is provided, including the electrical device and the above-mentioned battery pack, and the battery pack is used to supply power to the electrical device.

[0086] Specifically, the core feature of the electrical device is the integration of the aforementioned carefully designed battery pack. This electrical device not only has excellent performance and stability, but also stands out due to the high-efficiency power supply ability of the battery pack.

[0087] Taking a high-performance electric vehicle as an example, this vehicle uses the battery pack in this embodiment as its power source. The design of this battery pack fully considers the requirements of electric vehicles for long endurance and high safety. Through the integrated tray 1 and upper cover structure, it provides stable support and effective protection for the battery cells 5. The design of the exhaust component 6 and the partition 3 in the battery pack enables harmful gases to be quickly discharged when abnormal conditions occur in the battery cells 5, thus ensuring the safety during the driving of the electric vehicle.

[0088] In practical applications, this electric vehicle performs excellently due to the excellent performance of its battery pack. On the one hand, the high-efficiency power supply ability of the battery pack enables the electric vehicle to have a longer endurance mileage, meeting the needs of users for long-distance travel. On the other hand, the high-safety design of the battery pack makes the electric vehicle more stable and reliable during driving, reducing the risk of accidents.
