Description

Technical Field

[0001] This utility model relates to the field of new energy battery module technology, and in particular to an aluminum side plate structure for a new energy battery module. Background Technology

[0002] New energy battery modules are highly susceptible to transient impacts under various conditions, including vehicle collisions, lateral intrusions, drops, and transportation vibrations. To ensure the safety and stability of battery modules, their external structure must not only effectively absorb impact energy and limit intrusion within a limited space, but also prevent excessive peak forces from being transmitted back to the cells and busbars, thereby protecting the core components of the battery module. Aluminum side plates, as load-bearing and protective components of the battery module, are located close to the cells and participate in pre-tensioning and heat conduction, making them a key component for achieving energy absorption and safety synergy. However, existing side plates primarily rely on reinforcing ribs, frames, or elastic components, offering limited impact management capabilities.

[0003] Currently, springs, foam, rubber pads, honeycomb components, or simple yield zones are commonly used in the market to buffer impacts. While these solutions are simple and convenient, they have some inherent technical drawbacks. Some solutions rely primarily on elastic energy storage, which can cause the force to react back onto the battery module during the impact rebound phase, potentially leading to secondary impacts. Other solutions rely on one-time yielding, resulting in a high initial peak force and an unstable energy absorption curve, making it difficult to achieve graded responses based on impact strength. This limits their applicability in different impact scenarios. Furthermore, considering that existing new energy battery module side panels typically require cooling circuits, current publicly available solutions generally lack orderly management and controllable release of energy transfer paths, failing to effectively balance the needs of cooling and impact protection. Summary of the Invention

[0004] This utility model discloses an aluminum side plate structure for a new energy battery module, which aims to solve the shortcomings of existing new energy battery module side plates in terms of impact management capabilities and the coordinated operation of cooling and impact protection.

[0005] The technical solution of this utility model is as follows: This utility model discloses an aluminum side plate structure for a new energy battery module, comprising: A rhomboid component, the interior of which is provided with a liquid storage cavity for containing liquid; An energy-absorbing assembly, which has a piston mechanism and a liquid buffer chamber inside, the liquid buffer chamber being used to contain gas in the initial state; A flexible tube that connects the liquid storage chamber and the liquid buffer chamber.

[0006] This technical solution enables effective energy absorption and provides a graded energy absorption response, thereby achieving efficient impact energy management within a limited space.

[0007] Furthermore, the aluminum side panel structure of the new energy battery module also includes a baffle and a connector. The diamond-shaped component is disposed between the baffle and the battery module, and the connector is used to connect the baffle and the side panel.

[0008] This technical solution enables the diamond-shaped component to be effectively connected to the battery module and side plate, forming a complete protective structure and improving the overall impact resistance.

[0009] More specifically, in some embodiments, the connector includes an outer cylinder and an inner cylinder slidably disposed within the outer cylinder, and the connector also includes a spring and an air bladder.

[0010] This technical solution allows the connectors to provide additional cushioning and energy absorption through the combination of springs and airbags, further enhancing the structure's impact resistance.

[0011] Preferably, the aluminum side plate structure of the new energy battery module includes a piston mechanism comprising a first piston rod and a second piston rod arranged opposite to each other, with a first piston and a second piston respectively provided on the first piston rod and the second piston rod, and the first piston and the second piston together defining the liquid buffer chamber.

[0012] This technical solution enables the piston mechanism to precisely control the volume change of the liquid buffer chamber, thereby providing a controllable energy absorption effect.

[0013] Furthermore, the new energy battery module has an aluminum side plate structure, and the energy-absorbing component is also equipped with a telescopic spring, which is sleeved on the first piston rod.

[0014] This technical solution allows the telescopic spring to provide preload or rebound force to the piston rod, optimizing the working characteristics of the energy absorption component and improving energy absorption efficiency.

[0015] More specifically, in some embodiments, the connector is provided with a limiting post for limiting the stroke; the energy-absorbing assembly is provided with a limiting ring for limiting the stroke.

[0016] This technical solution enables the limiting posts and limiting rings to effectively control the movement of the connectors and energy-absorbing components, prevent excessive deformation, and ensure the stability of the structure under impact.

[0017] Preferably, the new energy battery module has an aluminum side plate structure, and the energy-absorbing component is provided with a connection port for replenishing liquid.

[0018] This technical solution allows for easy maintenance and adjustment of the energy-absorbing components via the connection port, ensuring their long-term stable operation.

[0019] Preferably, the new energy battery module has an aluminum side panel structure, and the energy-absorbing component is fixed by a mounting component.

[0020] This technical solution ensures that the energy-absorbing components are securely installed in the side panel structure, improving the overall structural reliability.

[0021] This utility model discloses an aluminum side plate structure for a new energy battery module. By setting up diamond-shaped parts, energy-absorbing components and hoses, it effectively solves the problems of limited impact management capability of side plates and difficulty in coordinating cooling circuit and energy absorption in the prior art.

[0022] Specifically, existing technologies commonly employ elastic energy storage solutions such as springs, foam, and rubber pads, or one-time yielding methods. These solutions suffer from drawbacks such as impact rebound force acting on the battery module, high initial peak force, and unstable energy absorption curves. This invention utilizes a liquid storage chamber within a rhomboid component to hold liquid. Through the elastic deformation of the spring, air bladder, and rhomboid cavity, minor impacts are initially absorbed, reducing the initial load transmitted to the battery cell. When the impact intensifies, coolant flows from the storage chamber into a liquid buffer chamber. Once the buffer chamber is full, it pushes the piston, further absorbing energy through liquid flow and spring deformation, thus stabilizing the force-displacement curve and reducing peak load. This structure effectively avoids the risks of hydraulic lock-up and liquid spraying in the cooling circuit, ensuring synergy between cooling and energy absorption functions. The symmetrical operation and limiting design of the dual pistons dissipate the impact force internally, reducing the reaction force on the battery cell and busbar. After the impact is released, the coolant automatically flows back, the spring and rhomboid cavity return to their original shape, and the structure can be quickly reset and reused. The overall solution balances heat dissipation, protection, and lightweighting within a limited space, significantly improving the safety and reliability of the battery module.

[0030] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application.

[0031] New energy battery modules are highly susceptible to transient impacts under various conditions, including vehicle collisions, lateral intrusions, drops, and transportation vibrations. To ensure the safety and stability of the battery module, its external structure must not only effectively absorb impact energy and limit intrusion within a limited space, but also prevent excessive peak forces from being transmitted back to the cells and busbars, thereby protecting the core components of the battery module. Aluminum side plates, as load-bearing and protective components of the battery module, are located close to the cells and participate in pre-tensioning and heat conduction, making them a key component for achieving energy absorption and safety synergy. However, existing side plates primarily rely on reinforcing ribs, frames, or elastic components, offering limited impact management capabilities. Currently, the market commonly uses springs, foam, rubber pads, honeycomb components, or simple yield zones to buffer impacts. These solutions are simple and convenient, but they have some inherent technical flaws. Some solutions mainly rely on elastic energy storage, which can cause the force to react back onto the battery module during the impact rebound phase, potentially leading to secondary impacts. Other solutions rely on one-time yielding, resulting in a high initial peak force and an unstable energy absorption curve, making it difficult to achieve graded responses based on impact strength. This limits their applicability in different impact scenarios. Furthermore, considering that existing new energy battery module side panels typically require cooling circuits, current publicly available solutions generally lack orderly management and controllable release of energy transfer paths, failing to effectively balance the needs of cooling and impact protection.

[0032] This utility model discloses an aluminum side plate structure for a new energy battery module, which aims to solve the shortcomings of existing new energy battery module side plates in terms of impact management capabilities and the coordinated operation of cooling and impact protection.

[0033] This embodiment discloses an aluminum side plate structure for a new energy battery module. (See also...) Figure 1 The device mainly comprises a rhomboid component 4, an energy-absorbing assembly 5, and a flexible hose 6. The rhomboid component 4 has an internal liquid storage chamber 41 for containing liquid, typically a coolant, used to cool the battery module in non-impact conditions. The energy-absorbing assembly 5 has an internal piston mechanism and a liquid buffer chamber 55, which is initially empty. The flexible hose 6 connects the liquid storage chamber 41 and the liquid buffer chamber 55, allowing the liquid in the rhomboid component 4 to enter the liquid buffer chamber 55 of the energy-absorbing assembly 5 through the hose 6 during an impact, thereby achieving energy transfer and absorption.

[0034] Specifically, the rhomboid component 4 is a key part of this structure, and its internal liquid storage chamber 41 is used to store coolant. This coolant not only provides heat dissipation for the battery module during daily operation, but also serves as an energy transfer medium in the event of an impact. The rhomboid component 4 can adopt various structural forms; for example, it can be designed as a cavity with a certain degree of elasticity so that it can undergo slight elastic deformation when subjected to impact, initially absorbing some of the impact energy. This geometry can provide a certain amount of deformation space when subjected to compression, thereby buffering the impact force in the initial stage.

[0035] The energy-absorbing component 5 is another core component of this structure. Its internal piston mechanism and liquid buffer chamber 55 work together to further absorb impact energy. Initially, the liquid buffer chamber 55 provides space for subsequent liquid entry. When the liquid inside the rhomboid member 4 is compressed under impact, it enters the liquid buffer chamber 55 through the hose 6, driving the piston mechanism to move or compressing the spring through the piston mechanism's movement to absorb energy. Its stroke and damping characteristics can be designed according to actual needs to achieve effective management of impact energy. The hose 6 acts as a bridge connecting the liquid storage chamber 41 of the rhomboid part 4 and the liquid buffer chamber 55 of the energy-absorbing assembly 5. This channel ensures that, upon impact, the liquid inside the rhomboid part 4 can flow smoothly into the energy-absorbing assembly 5, thereby initiating the energy absorption process. When the rhomboid part 4 is compressed and deformed, the hose 6 can deform along with it.

[0036] This application introduces a rhomboid component 4 and an energy-absorbing assembly 5, connecting them with a flexible hose 6 to form a buffer energy-absorbing system. Under minor impacts, the elastic deformation of the rhomboid component 4 and the spring and air bladder in the connector 3 can absorb some energy, avoiding direct impact on the battery module. When the impact increases further, the liquid inside the rhomboid component 4 is squeezed and enters the liquid buffer chamber 55 of the energy-absorbing assembly 5 through the flexible hose 6, pushing the piston mechanism to move and compressing the spring, thereby further absorbing the impact energy. This graded response mechanism allows the structure to adaptively adjust according to the impact intensity, improving the overall safety and reliability of the battery module.

[0037] The working principle of the aluminum side plate structure of this new energy battery module is as follows: In the initial state, the liquid storage chamber 41 of the rhomboid part 4, the hose, and the inner cavity of the energy absorption device are all filled with the same coolant medium. When the battery module is subjected to external impact, the impact force first acts on the side plate structure. Under slight impact, the rhomboid part 4 will undergo slight elastic deformation, and the spring on the connector 3 will also be slightly compressed, thereby initially absorbing some of the impact energy. At this time, only a small amount of coolant may enter the liquid buffer chamber 55 of the energy absorption component 5, but it is insufficient to drive the piston mechanism to move, thus avoiding unnecessary wear and stress.

[0038] As the impact force increases further, the rhomboid component 4 is further compressed, and the pressure inside the liquid storage chamber 41 rises accordingly. Due to the incompressibility of the liquid, the coolant rapidly enters the liquid buffer chamber 55 of the energy-absorbing assembly 5 through the hose 6. As the coolant rushes in, the gas inside the liquid buffer chamber 55 is compressed, simultaneously pushing the piston mechanism to move. The movement of the piston mechanism further absorbs the impact energy, driving the spring or other damping elements to dissipate energy. This displacement of the liquid and the movement of the piston mechanism convert the impact energy into the kinetic and potential energy of the spring, as well as the mechanical energy of the piston mechanism, thereby effectively reducing the peak force transmitted to the battery module.

[0039] After the impact dissipates, the piston mechanism within the energy-absorbing component 5 resets under the action of the internal spring, and the coolant in the liquid buffer chamber 55 flows back to the reservoir chamber 41 of the rhomboid component 4 through the hose 6, restoring the entire system to its initial state for reuse. During this process, the coolant in the rhomboid component 4 continuously cools the battery module in the non-impact state, achieving synergy between energy absorption and thermal management. Through this design, this structure not only effectively absorbs and manages impact energy, reducing the safety risks of the battery module, but also seamlessly integrates with the battery module's thermal management system, improving the overall safety performance of new energy vehicles.

[0040] Baffle 2 is a plate-like structure whose main function is to provide a supporting and insulating interface between the rhomboid component 4 and the battery module 1. Baffle 2 can be made of various materials, such as metal alloys and composite materials, to ensure sufficient strength and rigidity when subjected to impact. Connector 3 is a component used to mechanically connect baffle 2 to the side plate of the battery pack. The springs and airbags in connector 3 also provide initial impact resistance.

[0041] The solution proposed in this application effectively solves the connection and force transmission problem between the energy-absorbing structure and the battery module 1 and the side plate in the basic solution by introducing baffle 2 and connector 3.

[0042] In practical applications, the structural design of connector 3 is crucial to its stability and controllability during collision energy absorption. If the structure of connector 3 is too simple, it may not be able to effectively buffer when subjected to impact, or may exhibit inconsistent energy absorption effects under different impact intensities, thereby affecting the protection capability of the entire side plate structure for battery module 1.

[0043] In this regard, this application further proposes that the connector 3 includes an outer cylinder 33 and an inner cylinder 34 slidably disposed within the outer cylinder 33, and the connector 3 is also provided with a spring 31 and an airbag 32.

[0044] The outer cylinder 33 is typically designed as a tubular or sleeve-shaped structure with a certain strength and rigidity. Its function is to provide external support and guidance for the inner cylinder 34 and to serve as the external frame of the connector 3. The inner cylinder 34 is designed to slide axially within the outer cylinder 33; its fit clearance and surface treatment with the outer cylinder 33 affect the smoothness of the sliding. The spring 31 is typically a compression spring, which can be compressed when the connector 3 is impacted, thereby absorbing some of the impact energy and providing a restoring force after the impact, allowing the connector 3 to return to its original position. The airbag 32 is typically made of a flexible material and filled with gas. When compressed, the internal gas is compressed, providing additional cushioning and energy absorption. Furthermore, the compression characteristics of the airbag 32 can be non-linear to accommodate impacts of varying intensities.

[0045] The solution proposed in this application incorporates a combined structure of an outer cylinder 33, an inner cylinder 34, a spring 31, and an airbag 32 into the connector 3. This allows the inner cylinder 34 to slide controllably within the outer cylinder 33 under the combined action of the spring 31 and the airbag 32 when the connector 3 is subjected to an initial minor external impact. Specifically, when the battery module 1 experiences a slight impact, the impact force is first transmitted to the connector 3 through the baffle 2. At this time, the inner cylinder 34 slides within the outer cylinder 33, and the spring 31 is compressed, absorbing a portion of the impact energy. Simultaneously, the airbag 32 is also compressed, providing additional cushioning and energy absorption. This multi-mechanism energy absorption mechanism works synergistically to effectively prolong the impact time and reduce the impact peak, thereby significantly improving the energy absorption efficiency and stability of the connector 3.

[0046] Through the above technical solution, the connector 3 is endowed with more optimized initial energy absorption characteristics. The combined use of spring 31 and airbag 32 enables the connector 3 to provide a more linear or nonlinear energy absorption response when facing collisions of different intensities, thereby effectively avoiding the limitations that may exist with a single energy absorption element. This design not only enhances the buffering capacity of the connector 3, but also improves its controllability during the collision process. It ensures that in the event of a minor collision without deformation of the buffer, the connector 3 can stably absorb and disperse minor impact energy, maximizing the protection of the battery module 1 from damage, and thus improving the safety performance of the entire aluminum side plate structure of the new energy battery module.

[0047] This application further optimizes the internal structure of the energy absorption component 5. Specifically, the piston mechanism includes a first piston rod 51 and a second piston rod 52 arranged opposite to each other. A first piston 511 and a second piston 521 are respectively provided on the first piston rod 51 and the second piston rod 52. The first piston 511 and the second piston 521 together define the liquid buffer chamber 55.

[0048] Piston rod 51 and piston rod 52 are the main components of the piston mechanism, used to transmit force and control the movement of the piston. Piston 511 and piston 521 form a seal within the liquid buffer chamber 55, allowing the liquid to drive the piston and thus absorb energy. In a preferred embodiment, piston rod 51 and piston rod 52 can be made of high-strength alloy steel to ensure they do not break or deform under impact. Piston 511 and piston 521 can be made of wear-resistant and corrosion-resistant rubber or plastic to ensure a tight seal between them and the inner wall of the liquid buffer chamber 55.

[0049] In this application, the piston mechanism is designed to consist of a first piston rod 51 and a second piston rod 52, as well as a first piston 511 and a second piston 521, arranged opposite to each other. This allows the energy-absorbing component 5 to absorb impact energy from two directions. When impacted from the direction of the first piston rod 51, the first piston 511 stretches the spring under the push of the coolant, thereby absorbing a portion of the energy. Conversely, when impacted from the direction of the second piston rod 52, the second piston 521 compresses the spring under the push of the coolant, thereby absorbing the remaining energy. Therefore, regardless of the direction of the collision, the energy-absorbing component 5 can effectively absorb impact energy, thus improving the safety of the new energy battery module.

[0050] Through the above technical solution, this application can significantly improve the energy absorption efficiency and adaptability of the energy absorption component 5, thereby better protecting the new energy battery module from collision damage. Compared with the traditional unidirectional energy absorption structure, the bidirectional energy absorption structure of this application can better cope with various complex collision situations, thereby improving the safety of the new energy battery module.

[0051] This application adds a telescopic spring 56 inside the energy absorption assembly 5. The telescopic spring 56 is sleeved on the first piston rod 51 to enhance the energy absorption effect and improve the reliability of the structure.

[0052] The telescopic spring 56 is an elastic element that absorbs and releases energy through its own expansion and contraction. Specifically, the telescopic spring 56 can take various forms, such as a coil spring or a disc spring, and its material can be selected from materials with good elasticity and strength, such as spring steel or stainless steel. The stiffness coefficient and preload of the telescopic spring 56 can be adjusted according to actual needs to meet different energy absorption requirements.

[0053] Furthermore, when the aluminum side plate structure of the new energy battery module is impacted, piston rod 51 and piston rod 52 will move relative to each other, and the telescopic spring 56 sleeved on piston rod 51 will be compressed, thereby absorbing some of the impact energy. Through the buffering effect of the telescopic spring 56, the movement speed of the piston rod can be effectively reduced, preventing direct collision and thus improving the energy absorption effect and structural reliability. In addition, the telescopic spring 56 can also provide additional buffering under smaller impact forces, thereby improving the adaptability of the structure.

[0054] When the aluminum side panel structure of the new energy battery module is impacted, connector 3 is impacted first. Inner cylinder 34 slides within outer cylinder 33, spring 31 is compressed, and airbag 32 expands, thus absorbing some of the impact energy. When the sliding stroke of inner cylinder 34 reaches the limit of limit post 35, limit post 35 will prevent inner cylinder 34 from sliding further. At the same time, energy-absorbing component 5 is also impacted. Piston rod 51 and piston rod 52 move closer to each other, and piston rod 511 and piston rod 521 compress the liquid buffer chamber 55, thus absorbing some of the impact energy. When the movement stroke of piston rod 51 and piston rod 52 reaches the limit of limit ring 57, limit ring 57 will prevent piston rod 51 and piston rod 52 from moving further.

[0055] Therefore, through the dual limiting effect of the limiting post 35 and the limiting ring 57, the deformation degree of the connector 3 and the energy absorption component 5 can be effectively controlled to avoid their failure, thereby ensuring the safety of the aluminum side plate structure of the new energy battery module.

[0056] In practical applications, the liquid volume inside the energy-absorbing component 5 may need to be adjusted according to different operating conditions to achieve the best energy absorption effect. To address this, this application proposes providing a connection port 53 for liquid replenishment on the energy-absorbing component 5. Through the connection port 53, the internal parameters of the energy-absorbing component 5 can be easily adjusted, thereby optimizing its performance.

[0057] Connection port 53 refers to an interface provided on the energy-absorbing component 5. This interface can be used to drain or replace the coolant inside the energy-absorbing component 5, or to replenish the coolant inside the energy-absorbing component 5. Specifically, connection port 53 can be an interface with a valve, and the injection of coolant can be controlled by opening and closing the valve. As a preferred embodiment, connection port 53 can be in the form of a quick connector to facilitate quick connection and disconnection of the coolant source.

[0058] The above technical solution facilitates the maintenance and upkeep of the energy-absorbing component 5, extending its service life.

[0059] The energy-absorbing component 5 is fixed by the mounting piece 54. This design can more securely install the energy-absorbing component 5 on the aluminum side plate structure of the new energy battery module, ensuring that it can effectively play its energy-absorbing role when subjected to impact.

[0060] The mounting component 54 can take various forms; for example, it can be fixed to the side plate using bolts, clips, or adhesive. As a preferred embodiment, the mounting component 54 can be designed with a certain degree of elasticity to provide cushioning during impacts, further improving the energy absorption effect.

[0061] By fixing the energy-absorbing component 5 with the mounting bracket 54, displacement or detachment of the energy-absorbing component 5 can be effectively prevented when subjected to impact, thereby ensuring that it can fully exert its energy-absorbing function and protect the safety of the battery module 1. At the same time, fixing the energy-absorbing component 5 with the mounting bracket 54 also facilitates the replacement and maintenance of the energy-absorbing component 5, and improves the overall reliability and maintainability of the aluminum side plate structure of the new energy battery module.

[0062] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
