Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and more specifically, to a housing assembly, a battery module, and a battery system. Background Technology

[0002] Currently, battery modules are widely used due to their high energy density and long service life. As the energy density of battery cells continues to increase, the heat generated by battery modules during operation also increases accordingly. Excessive temperature will increase the safety risks of battery modules.

[0003] In existing technology, workers typically install a liquid cooling plate on the housing, and then attach the battery module to the liquid cooling plate using thermally conductive structural adhesive, so that the battery module is cooled by the cooling medium flowing through the liquid cooling plate.

[0004] However, in the actual operation of the battery module, since the battery module and the liquid cooling plate are independent of each other, under the influence of external vibration, the battery module is prone to separation from the liquid cooling plate, thereby reducing the heat dissipation efficiency of the battery module and affecting the operational safety of the battery module. Utility Model Content

[0005] The main objective of this invention is to provide a housing assembly, a battery module, and a battery system to address the problem of low operational safety in existing battery modules.

[0010] Furthermore, the housing assembly also includes a limiting structure, which is disposed on the hole wall and contacts the end of the battery cell near the cooling structure to limit the battery cell.

[0011] Furthermore, the housing assembly also includes a sealing compound disposed within the receiving space to fill the gap between the battery cell and the enclosure structure.

[0012] Furthermore, the elastic structure includes: a main body portion disposed on the hole wall; and a guide portion disposed on the end of the main body portion away from the cooling structure. Along the direction from the main body portion to the guide portion, the diameter of at least a portion of the guide portion gradually decreases, so that at least a portion of the outer peripheral surface of the guide portion forms a conical structure.

[0013] Furthermore, there are multiple elastic structures, which are spaced apart along the extension direction of the hole wall to keep the outer peripheral surface of the battery cell in contact with the hole wall. Alternatively, there are multiple elastic structures, which are spaced apart around the axis of the mounting hole, and the multiple elastic structures surround each other to form a clamping space to clamp the battery cell.

[0045] To address the issue of low operational safety in existing battery modules, this application provides a housing assembly, a battery module, and a battery system.

[0046] like Figures 1 to 8 As shown, the housing assembly includes a cooling structure 10, a surrounding structure 20, a mounting structure 30, and a resilient structure 40. The surrounding structure 20 is disposed on the cooling structure 10, and at least a portion of the surrounding structure 20 and the cooling structure 10 surround to form a receiving space 21 for accommodating the battery cell 1. The mounting structure 30 is disposed within the receiving space 21 and has a mounting hole 31 for connecting the battery cell 1 to the cooling structure 10 through the mounting hole 31. The resilient structure 40 is disposed on the wall of the mounting hole 31 to maintain contact between the outer peripheral surface of the battery cell 1 and the hole wall.

[0047] Applying the technical solution of this embodiment, the enclosure structure 20 of the housing assembly is disposed on the cooling structure 10, and the enclosure structure 20 and at least a portion of the cooling structure 10 surround each other to form a receiving space 21, which is used to receive the battery cell 1. A mounting structure 30 is disposed within the receiving space 21, and the mounting structure 30 has a mounting hole 31 so that the battery cell 1 can be connected to the cooling structure 10 through the mounting hole 31. An elastic structure 40 is disposed on the hole wall of the mounting hole 31 so that the outer peripheral surface of the battery cell 1 remains in contact with the hole wall. In this way, the arrangement of the cooling structure 10, on the one hand, can be combined with the enclosure structure 20 to achieve reliable housing of the housing assembly, ensure the structural strength of the housing assembly, and reduce production costs, thus achieving the economy of the battery module; on the other hand, it can directly contact the battery cell 1, reducing the temperature of the battery cell 1 and ensuring the heat dissipation reliability and operational reliability of the battery cell 1. Therefore, the battery module achieves both structural strength and heat dissipation reliability, thereby solving the problem of low operational safety of battery modules in the prior art. Meanwhile, the flexible structure 40 allows the battery cell 1 to be securely installed on the mounting structure 30, preventing the battery cell 1 from shaking and rotating due to external vibration, thus ensuring the installation stability and operational reliability of the battery cell 1.

[0048] In this embodiment, the cooling structure 10 is a liquid cooling plate.

[0049] In this embodiment, the mounting structure 30 is injection molded. (Instruction manual PN305185HZYWLN)

[0050] like Figures 4 to 6 As shown, the mounting structure 30 is a rectangular plate with multiple mounting holes 31. These mounting holes 31 are divided into multiple groups, each group containing multiple mounting holes 31. The groups of mounting holes 31 are spaced apart along the length of the mounting structure 30, and the mounting holes 31 within each group are spaced apart along the width of the mounting structure 30. This arrangement of multiple mounting holes 31 allows the mounting structure 30 to effectively support and fix multiple battery cells 1, ensuring a tight layout between the multiple battery cells 1 and between the multiple battery cells 1 and the cooling structure 10. This achieves the integration of multiple battery cells 1 within a limited space, thereby guaranteeing the high energy density of the battery module. Simultaneously, the arrangement of the mounting structure 30 simplifies its formation, making it easier to manufacture and implement, reducing the processing difficulty for workers and improving their work efficiency.

[0051] like Figure 1As shown, the housing assembly also includes a connecting adhesive 50, which is disposed on the cooling structure 10 to connect the cooling structure 10 to the mounting structure 30 and the battery cell 1. At least a portion of the connecting adhesive 50 is made of a thermally conductive material. This arrangement of the connecting adhesive 50 serves two purposes: firstly, it establishes a connection between the cooling structure 10, the mounting structure 30, and the battery cell 1, simplifying assembly procedures and improving worker efficiency; secondly, it transfers heat from the battery cell 1 to the cooling structure 10, ensuring reliable heat dissipation for the battery cell 1. Simultaneously, this arrangement prevents separation between the cooling structure 10 and the battery cell 1 due to external forces or deformation of the housing assembly, ensuring a stable connection and reliable heat dissipation between the battery cell 1 and the cooling structure 10. This reduces the probability of battery module breakage, improves the structural strength of the battery module, and guarantees the operational and heat dissipation reliability of the battery module.

[0052] In this embodiment, the connecting adhesive 50 is a thermally conductive structural adhesive.

[0053] Instruction manual PN305185HZYWLN

[0054] like Figure 7 As shown, the housing assembly also includes a limiting structure 60, which is disposed on the hole wall and contacts the end of the battery cell 1 near the cooling structure 10 to limit the battery cell 1. This arrangement of the limiting structure 60 ensures the precise position of the battery cell 1 within the mounting hole 31 and also guarantees high consistency among multiple battery cells 1, achieving consistent heat conduction between multiple battery cells 1 and the cooling structure 10.

[0055] In this embodiment, the limiting structure 60 can also ensure the height of the connecting colloid 50, avoiding the excessive compression of the connecting colloid 50 by the cell 1 due to inconsistent battery height, which would reduce the thermal conductivity and viscosity of the connecting colloid 50, thereby ensuring the thermal conductivity and connection reliability of the connecting colloid 50, and thus ensuring the heat dissipation reliability and operational reliability of the battery module.

[0056] like Figure 1As shown, the housing assembly also includes a sealing colloid 70, which is disposed within the receiving space 21 to fill the gap between the battery cell 1 and the surrounding structure 20. This arrangement of the sealing colloid 70 serves two purposes: firstly, it hardens after filling the gap, enhancing the connection stability between the battery cell 1 and the surrounding structure 20, strengthening the structural strength of the housing assembly, and further improving the structural strength of the battery module; secondly, it compensates for irregular gaps between the battery cells 1, preventing short circuits caused by compression between multiple cells 1, optimizing the spatial arrangement of multiple cells 1, improving the operational safety and reliability of the battery module, and further ensuring the high energy density of the battery module.

[0057] In this embodiment, the sealing adhesive 70 is a foam adhesive.

[0058] like Figure 7 As shown, the elastic structure 40 includes a main body 41 and a guide portion 42. The main body 41 is disposed on the wall of the hole. The guide portion 42 is disposed on the end of the main body 41 away from the cooling structure 10. Along the direction from the main body 41 to the guide portion 42, the diameter of at least a portion of the guide portion 42 gradually decreases, so that at least a portion of the outer peripheral surface of the guide portion 42 forms a conical structure. In this way, the above arrangement provides guidance for the battery cell 1 during the installation or removal process, ensuring the smooth installation and removal of the battery cell 1, reducing the difficulty of the work for the workers, and improving the work efficiency of the workers.

[0059] In this embodiment, both the main body 41 and the guide part 42 are connected to the hole wall.

[0060] Specifically, multiple elastic structures 40 are arranged at intervals along the extension direction of the hole wall to keep the outer peripheral surface of the battery cell 1 in contact with the hole wall. Alternatively, multiple elastic structures 40 are arranged at intervals around the axis of the mounting hole 31, forming a clamping space to clamp the battery cell 1. In this way, multiple elastic structures 40 can accommodate battery cells 1 of different specifications and sizes, improving the installation versatility of the mounting structure 30 and the versatility of the housing assembly. Simultaneously, when multiple elastic structures 40 are arranged around the hole wall of the mounting hole 31, they can clamp the battery cell 1, ensuring the installation stability of the battery cell 1 while protecting it from damage caused by external forces, thus improving the shock resistance of the battery cell 1 and enhancing the operational reliability and safety of the battery module.

[0061] In this embodiment, three elastic structures 40 are provided, and the three elastic structures 40 are spaced apart around the axis of the mounting hole 31.

[0062] It should be noted that the number of elastic structures 40 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of elastic structures 40 can be two, four, five, seven, or more.

[0063] like Figure 8 As shown, the limiting structure 60 is plate-shaped, and at least a portion of its edges away from the hole wall are chamfered 61. This design makes the edges of the limiting structure 60 smoother, reducing the risk of damage to the outer surface of the battery cell 1 and further ensuring the operational reliability and safety of the battery cell 1.

[0064] Instruction manual PN305185HZYWLN

[0065] Specifically, there are multiple limiting structures 60, which are spaced apart around the axis of the mounting hole 31. In this way, the multiple limiting structures 60 can balance the weight of the battery cell 1, improve the precise position of the battery cell 1 in the mounting hole 31, further ensure the high consistency between the multiple battery cells 1, and improve the heat conduction consistency between the multiple battery cells 1 and the cooling structure 10.

[0066] In this embodiment, the number of limiting structures 60 is three.

[0067] It should be noted that the number of limit structures 60 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of limit structures 60 can be two, four, five, seven, or more.

[0068] like Figure 2 and Figure 3 As shown, the cooling structure 10 and the enclosure structure 20 are integrally formed. This arrangement enhances the structural strength of the housing assembly, improves its impact resistance and rigidity, and further strengthens the structural integrity and overall strength of the battery module. Simultaneously, this arrangement simplifies the assembly process, reduces the workload for workers, and increases their efficiency.

[0069] In this embodiment, the liquid cooling plate includes a flow channel plate and a flow plane plate. The flow plane plate is connected to the enclosure structure 20, and the flow plane plate and the enclosure structure 20 are integrally formed by die casting. The flow plane plate and the flow channel plate are brazed together, and the flow channel plate is formed by sheet metal stamping.

[0070] In this embodiment, the enclosure structure 20 and the cooling structure 10 are integrally formed, which avoids the overflow of the connecting adhesive 50 and the sealing adhesive 70 before solidification, thus avoiding waste of production materials, reducing production costs, and improving the economic efficiency of the battery module.

[0071] Specifically, the workers first install multiple battery cells 1 into the mounting holes 31. Then, they apply thermally conductive structural adhesive to the cooling structure 10. The workers then place the mounting structure 30 with the battery cells 1 installed onto the thermally conductive structural adhesive. After the adhesive solidifies, the mounting structure 30 and the multiple battery cells 1 are firmly bonded to the cooling structure 10. Next, the workers fill the accommodating space 21 of the PN305185HZYWLN instruction manual with expanding foam. The expanding foam fills the gaps between the multiple battery cells 1 and the gaps between the battery cells 1 and the surrounding structure 20. After the expanding foam solidifies, the multiple battery cells 1 and the surrounding structure 20 are integrated, enhancing the structural strength of the battery module.

[0072] This application also provides a battery module (not shown) that includes the aforementioned housing assembly.

[0073] This application also provides a battery system (not shown) that includes the battery module described above.

[0074] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0075] The enclosure structure of the housing assembly is mounted on the cooling structure, and at least a portion of the enclosure structure and the cooling structure surround each other to form a receiving space for accommodating the battery cell. A mounting structure is disposed within the receiving space, and the mounting structure has mounting holes for connecting the battery cell to the cooling structure through the mounting holes. An elastic structure is disposed on the wall of the mounting holes to keep the outer peripheral surface of the battery cell in contact with the hole wall. This arrangement of the cooling structure, on the one hand, integrates with the enclosure structure, ensuring the housing assembly's reliability and structural strength, while also reducing production costs and achieving the economic efficiency of the battery module; on the other hand, it allows direct contact with the battery cell, reducing the cell's temperature and ensuring reliable heat dissipation and operational reliability. This allows the battery module to achieve both structural strength and reliable heat dissipation, thus solving the problem of low operational safety in existing battery modules. Simultaneously, the elastic structure ensures the battery cell is securely mounted on the mounting structure, preventing shaking and rotation caused by external vibrations, thus guaranteeing the cell's installation stability and operational reliability.

[0076] In the description of this utility model, it should be understood that directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship of the specification PN305185HZYWLN, which are generally based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0077] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0078] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0079] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
