Description

[0002] As the power tool industry continues to evolve towards lighter and more portable designs, the use of rechargeable batteries as a power source has become a major design trend. Among the many types of batteries, pouch cells offer advantages such as light weight and high energy density, effectively meeting the stringent size and weight requirements of power tools while providing longer working hours and higher efficiency.
[0003] However, in practical applications, due to their material properties, pouch cells undergo a certain degree of volume change during charge-discharge cycles. Existing battery casing designs typically provide large housing chambers for pouch cells without precisely matching their specific dimensions.

This lack of effective physical constraints allows the pouch cell to shift position during operation due to volume expansion or contraction, affecting battery consistency and stability. Furthermore, irregular movement can damage the internal structure of the cell, reducing battery safety and lifespan. Moreover, low space utilization limits further increases in battery capacity, hindering the maximization of power tool performance. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0023] Due to their material properties, pouch cells undergo a certain degree of volume change during charge-discharge cycles. Existing battery casing designs typically provide large housing chambers for pouch cells without precisely matching their specific dimensions. This results in gaps between the inner wall of the chamber and the various surfaces of the pouch cell, preventing a tight fit. This lack of effective physical constraints allows the pouch cell to shift position during operation due to volume expansion or contraction, affecting battery consistency and stability. Furthermore, irregular movement can damage the internal structure of the cell, reducing battery safety and lifespan. Moreover, low space utilization limits further increases in battery capacity, hindering the maximization of power tool performance.
[0024] To address the aforementioned technical problems, embodiments of this application provide a cell housing structure and a pouch battery.
[0025] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, this application provides a battery cell housing structure, including a first half-shell 101 and a mounting bracket 100; the first half-shell 101 has a connected base plate 102 and a shell sidewall 103; the mounting bracket 100 includes a mounting partition 104 and a first side plate 105 perpendicularly connected to the mounting partition 104, the mounting partition 104 is parallel and spaced apart from the base plate 102, and the first side plate 105 extends toward the base plate 102; the mounting partition 104, the base plate 102, and the first side plate 105 form a housing chamber for accommodating a soft-pack battery cell 114, the mounting partition 104 and the base plate 102 extend horizontally toward the surface of the housing chamber, and the first side plate 105 extends vertically toward the surface of the housing chamber.
[0026] It should be noted that, in this embodiment of the application, a mounting bracket 100 is provided above the first half-shell 101. The mounting bracket 100 includes a vertical mounting partition 104 and a first side plate 105. The mounting bracket 100 and the first half-shell 101 together form a structurally regular receiving chamber. This chamber is cuboid or cubic in shape, and its internal dimensions can be precisely matched with the shape of the soft-pack battery cell 114.
[0027] Among them, reference Figure 3 and Figure 4 As shown, the mounting partition 104 is arranged parallel to the base plate 102 and spaced a certain distance apart. The first side plate 105 is vertically connected to the mounting partition 104 and extends towards the base plate 102, so that the top, bottom, and side surfaces of the receiving chamber are all flat constraint surfaces. After the soft-pack battery cell 114 is installed into the receiving chamber, its surfaces can fit against the inner wall of the chamber, thereby being uniformly physically constrained during the volume change caused by charging and discharging, effectively limiting its free movement and excessive expansion within the chamber.
[0028] It should be noted that the external structure of the first half-shell 101 may have a curvature to meet the shape requirements of the soft-pack battery.
[0029] The technical effects that the embodiments of this application can produce are as follows: This embodiment of the application achieves all-round constraint on the pouch cell 114 through a regular receiving chamber, significantly improving the stability and consistency of the cell during operation, reducing internal structural damage caused by positional displacement or irregular expansion, and improving battery safety and cycle life. This embodiment of the application optimizes space utilization efficiency through a regular cuboid or cubic chamber, increasing the energy density of the battery pack, which is beneficial for fully utilizing battery performance in applications such as power tools. As an optional implementation, the distance between the mounting partition 104 and the base plate 102 can be set to match the thickness of the soft-pack battery cell 114.
[0030] It should be noted that the battery cell includes the battery cell body and a thermally conductive silicone layer that adheres to the battery cell body. The thermally conductive silicone layer has a certain degree of elasticity, which can achieve the effects of heat conduction and vibration damping. It should also be noted that by setting the distance between the mounting partition 104 and the bottom plate 102 of the first half-shell 101 to match the thickness of the soft-pack battery cell 114, after the battery cell is installed in the receiving chamber, its upper surface is in direct contact with the surface of the mounting partition 104 facing the chamber, and its lower surface is in direct contact with the surface of the bottom plate 102 facing the chamber, thereby forming a constraint structure with upper and lower double-sided adhesion in the thickness direction of the battery cell. This design ensures that the soft-pack battery cell 114 has surface contact with the top and bottom inner walls of the chamber before expansion. When the volume of the battery cell body changes during charging and discharging, the upper and lower walls can provide a uniform reaction force to the thermally conductive silicone layer, limiting excessive deformation or misalignment of the battery cell body.
[0031] In terms of effectiveness, the embodiments of this application significantly improve the physical fixation effect of the soft-pack cell 114 through precise size matching and surface contact constraints in the vertical direction, effectively suppress the disordered expansion and contraction of the cell in the thickness direction, reduce the risk of internal material fatigue and interface peeling caused by repeated deformation, thereby improving the safety, cycle stability and service life of the battery.
[0032] As an alternative implementation, there are two parallel spaced first side plates 105 connected to the mounting partition 104, the spacing between the two first side plates 105 matching the width of the pouch cell 114.
[0033] It should be noted that, in this embodiment of the application, two parallel spaced first side plates 105 are set and perpendicularly connected to the mounting partition 104, so that the distance between them matches the width of the soft-pack battery cell 114, thereby forming an effective limiting structure on both sides of the receiving chamber.
[0034] When the pouch cell 114 is inserted into the receiving chamber formed by the mounting partition 104, the base plate 102, and the two first side plates 105, its two sides can fit against the inner surfaces of the two first side plates 105, achieving effective constraint in the lateral direction. Through the above design, the volume change of the cell due to expansion or contraction during charge-discharge cycles can be controlled in this embodiment, while the width direction is firmly restricted to prevent lateral displacement or deformation instability.
[0035] In terms of effectiveness, the embodiments of this application significantly enhance the structural stability of the battery cell during operation by limiting the width direction of the battery cell through the first side plates 105 on both sides, avoiding stress concentration and internal damage caused by lateral movement or uneven expansion, and improving the safety and cycle life of the battery; at the same time, the limiting structure helps to maintain the fit between the battery cell and the chamber, improving the compactness and space utilization of the overall structure.
[0036] Reference Figure 2 , Figure 3 , Figure 4 As shown, in an optional embodiment, the mounting bracket 100 is further provided with a second side plate 106 perpendicularly connected to the mounting partition 104. The second side plate 106 extends toward the bottom plate 102 and is perpendicular to the first side plate 105. The first half-shell 101 has a vertically extending support plate 109 at the end away from the second side plate 106. The second side plate 106, the support plate 109, the mounting partition 104, the bottom plate 102, and the first side plate 105 together form a receiving chamber. The second side plate 106 and the support plate 109 extend vertically toward the surface of the receiving chamber. The support plate 109 and the second side plate 106 are parallel and spaced apart, and the distance between them is greater than the length of the pouch cell (excluding the tabs).
[0037] It should be noted that, in this embodiment of the application, a second side plate 106 is added to the mounting bracket 100 and is perpendicularly connected to the mounting partition 104. This side plate 106 cooperates with the support plate 109 provided at the other end of the first half-shell 101 to form the two-end structure of the receiving chamber. The support plate 109 is located at the end of the first half-shell 101 away from the second side plate 106 and is perpendicular to the bottom plate 102, and is arranged parallel to and spaced apart from the second side plate 106.
[0038] The embodiment of this application uses this design so that the receiving chamber is defined in the length direction by the second side plate 106 and the support plate 109, and the distance between the two is greater than the length of the soft-pack battery cell (excluding the tabs). This design provides a safe space for the slight expansion of the battery cell in the length direction during charging and discharging, while maintaining the overall enclosure of the structure and ensuring that the battery cell is mainly controlled and constrained in the thickness and width directions.
[0039] In terms of effectiveness, this embodiment of the application, by setting the second side plate 106 and the support plate 109 to form a longitudinally enclosing structure, ensures the structural integrity of the receiving chamber while also taking into account the slight longitudinal deformation requirements of the soft-pack battery cell 114 during operation, avoiding stress concentration caused by complete rigid sealing. This design not only improves the reliability and structural stability of the battery cell installation, but also effectively releases some of the expansion stress, extending the service life of the battery cell.
[0040] In addition, the layout of this application embodiment simplifies the assembly process, facilitates the insertion and positioning of the soft-pack battery cell 114, improves production efficiency, and at the same time preserves the space for the external curvature design of the battery casing, achieving coordinated optimization of structural strength, safety performance and aesthetic appearance.
[0041] As an optional implementation, the second side plate 106 is detachably inserted into the housing side wall 103.
[0042] It should be noted that, in this embodiment, the second side plate 106 is designed as a detachable structure. By inserting it into the housing side wall 103 of the first half-shell 101, a detachable modular connection is achieved between the mounting bracket 100 and the first half-shell 101. The second side plate 106 is vertically connected to the mounting partition 104 and is inserted into a pre-set slot or positioning structure in the housing side wall 103 during assembly, thereby forming a stable limiting wall at one end of the receiving chamber.
[0043] The detachable connection method of this application embodiment allows the mounting bracket 100 to be assembled after the first half-shell 101 is formed. This facilitates positioning the soft-pack battery cell 114 between the base plate 102 and the mounting partition 104 during the assembly process, and then completing the chamber closure by inserting the second side plate 106, thus optimizing the assembly process.
[0044] Specifically, refer to Figure 2 , Figure 3 As shown, the second side plate 106 is provided with a first snap-fit part 107 on the side near the housing side wall 103; the housing side wall 103 is provided with a second snap-fit part 108, and the first snap-fit part 107 and the second snap-fit part 108 are snapped together accordingly.
[0045] It should be noted that, in this embodiment, a first snap-fit portion 107 is provided on the side of the second side plate 106 near the housing side wall 103, and a corresponding second snap-fit portion 108 is provided on the housing side wall 103. The snap-fit between the two achieves a detachable connection between the second side plate 106 and the first half-housing 101. The first snap-fit portion 107 and the second snap-fit portion 108 adopt a complementary structural design, for example, they can be configured as a combination of "slot and snap-fit protrusion" or "slot and snap-fit protrusion". When the second side plate 106 is inserted into the housing side wall 103, the first snap-fit portion 107 and the second snap-fit portion 108 are precisely aligned and interlock, forming a stable mechanical connection, thereby firmly fixing the second side plate 106 to the first half-housing, and together with other structures, forming a complete cell housing chamber. This snap-fit method allows for rapid assembly and positioning without the need for additional fasteners.
[0046] In terms of effectiveness, the snap-fit structure design of this application significantly improves the ease of installation and connection reliability of the second side plate 106, enabling rapid and accurate assembly between the mounting bracket 100 and the first half-shell, thereby improving production efficiency and automation. Furthermore, this connection method facilitates disassembly, which is beneficial for later maintenance or component replacement, enhancing the maintainability and modularity of the battery structure, making it suitable for mass production of soft-pack batteries with high reliability requirements.
[0047] Furthermore, refer to Figure 2 , Figure 3 As shown, the support plate 109 has a slot 110 at its top; the mounting partition 104 has an overlapping portion 111; the overlapping portion 111 is fitted into the slot 110. The slot 110 is formed by a recess in the middle of the top surface of the support plate 109. The mounting partition 104 has abutment portions 116 on both sides of the overlapping portion 111. In the length direction, the overlapping portion 111 protrudes relative to the abutment portion 116, and the abutment portion 116 abuts against the side wall of the support plate 109 facing the receiving chamber, generating a blocking force that prevents the mounting partition 104 from moving in the length direction. Therefore, the cooperation between the overlapping portion 111 and the slot 110 provides not only vertical support but also horizontal support.
[0048] It should be noted that, in this embodiment, a slot 110 is provided on the top of the support plate 109, and a corresponding overlapping portion 111 is provided on the mounting partition 104. When the mounting bracket 100 is assembled with the first half-shell 101, the overlapping portion 111 is embedded in the slot 110 on the top of the support plate 109, forming a stable overlapping connection structure. This design allows one end of the mounting partition 104 to be positioned and fixed to the support plate 109 through the overlapping portion 111, while the other end is connected to the shell side wall 103 through the snap-fit of the second side plate 106, thereby stably positioning the entire mounting bracket 100 within the first half-shell 101, ensuring the geometric accuracy and structural stability of the receiving chamber.
[0049] In terms of effectiveness, the embodiments of this application achieve a reliable connection between the mounting partition 104 and the support plate 109 through the cooperation of the overlapping part 111 and the slot 110, which significantly improves the overall rigidity and structural stability of the mounting bracket 100 and effectively prevents the bracket from loosening or deforming under the condition of cell expansion or external vibration. At the same time, this connection method can achieve precise positioning and rapid assembly without additional fasteners, which further improves assembly efficiency and process consistency.
[0050] Reference Figure 3 As shown, in one optional implementation, the first side plate 105 has an L-shaped structure; the long side of the L-shaped structure is connected to the mounting partition 104; and the short side of the L-shaped structure is connected to the second side plate 106.
[0051] It should be noted that the first side plate 105 adopts an L-shaped structure, which can provide initial positioning of the battery cell during installation and improve assembly stability. At the same time, the battery cell can be further positioned using the shell sidewall opposite to the first side plate 105, without having to make the first side plate 105 rectangular. The L-shaped first side plate 105 in this embodiment significantly improves the structural strength and assembly stability of the mounting bracket 100, effectively preventing bracket deformation or loosening of connections under battery cell expansion or external impact. Meanwhile, the L-shaped first side plate 105 is connected to the mounting partition 104 and the second side plate 106 through its long and short sides, respectively, enhancing the connection rigidity and collaborative load-bearing capacity between the components and improving the all-round constraint effect of the housing chamber on the soft-pack battery cell 114.
[0052] Reference Figure 1 , Figure 3 As shown, in one optional implementation, the pouch cell 114 has a tab at one end near the second side plate 106; the first side plate 105 has an injection hole 112 at the part near the second side plate 106 for injecting sealant to seal the tab.
[0053] It should be noted that, for the layout of the pouch cell 114 with a tab at one end near the second side plate 106, a sealant injection channel is formed by opening a potting hole 112 in the adjacent first side plate 105. After the pouch cell 114 is assembled, sealant can be injected into the area where the tab is located through the potting hole 112, allowing the sealant to flow and cover the tab and its connection with the cell film / circuit board, thereby sealing the tab area.
[0054] In terms of effectiveness, the embodiments of this application achieve efficient and precise sealing of the tab area by setting the potting hole 112, which significantly improves the moisture-proof, dust-proof and insulation performance of the soft pack battery, and enhances the safety and long-term stability of the battery in complex environments. At the same time, the potting hole 112 is integrated on the first side plate 105, without taking up additional space, which is conducive to maintaining the compactness of the battery structure and high space utilization.
[0055] Reference Figure 4 , Figure 5 As shown, the pouch battery provided in this embodiment includes a second half-shell 115, a pouch cell 114, and the aforementioned cell housing structure; the pouch cell 114 is disposed within the cell housing structure; the second half-shell 115 is detachably connected to the first half-shell 101. The second half-shell 115 and the first half-shell 101 form the battery casing to protect the internal structure. The pouch battery also includes a main control board 113, which is mounted on the side of the mounting partition 104 opposite to the pouch cell 114.
[0056] It should be noted that, in this embodiment, the main control board 113 is mounted on the side of the mounting partition 104 opposite to the pouch cell 114, achieving a spatially integrated distributed layout of the battery management system and the cell housing structure. The mounting partition 104 serves as a functional separator, with one side forming a housing chamber for the pouch cell 114, and the other side used to fix the main control board 113. When the first half-shell 101 and the second half-shell 115 are engaged, both the main control board 113 and the mounting bracket 100 are sealed and protected inside the battery housing. This design utilizes the dual-sided functional characteristics of the mounting partition 104 to house the electronic control components and the pouch cell 114 in the same housing, saving overall space and achieving a compact layout of electrical connections through structural integration.
[0057] This embodiment of the application significantly improves the space utilization and structural integration of the pouch battery by integrating the main control board 113 mounting function on the mounting partition 104, avoiding the problems of increased size and complex wiring caused by the external placement of the main control board 113 in traditional designs. The main control board 113 is arranged close to the pouch cell 114, which helps to shorten the connection lines, reduce contact resistance and signal interference, and improve the response speed and control accuracy of the battery management system. At the same time, the main control board 113 is encapsulated in a robust housing, receiving effective mechanical protection and environmental isolation, which enhances its working stability and reliability under harsh conditions such as vibration and humidity.
[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
