Description

Technical Field

[0001] This application relates to the technical field of batteries, and particularly to a core installation device, a battery module, and a mobile power supply. Background Art

[0002] At the forefront of energy storage technology, the battery core is undoubtedly the key to the performance and reliability of the entire system. However, even for the same type of battery cores from the same manufacturer, minor dimensional differences can still occur due to tolerance issues during the manufacturing process. These seemingly insignificant changes can trigger a series of chain reactions in actual applications.

[0003] Specifically, the axial length of the battery core may fluctuate by ±0.3 millimeters. This dimensional inconsistency makes the fixation of the battery core in the plastic frame unstable. The random placement of the battery cores further exacerbates this problem, resulting in smaller-sized battery cores wobbling within the frame. This wobbling not only reduces the stability of the battery cores but may also impact the series and parallel metal electrodes at both poles of the battery cores, ultimately leading to connection failures and affecting the performance of the entire energy storage system. If these dimensional tolerances are ignored, the wobbling of the battery cores in the frame will impact the metal connection pieces, thereby affecting the long-term reliability of the product.

[0004] In related technologies, before placing the battery core into the frame, glue is applied first. At this time, the structural glue is in a paste state, and then the battery core is placed in to complete the module assembly. After the module is left standing for a period of time, the structural glue cures and fills the fitting gap between the battery core and the frame caused by the tolerance of the battery core, ensuring that the battery core cannot wobble. Although this method can effectively fix the battery core, it has a high cost, the dispensing process is complex, and a certain standing time is required. In addition, during rework, it is also difficult to remove the glue. Summary of the Utility Model

[0005] The embodiments of this application provide a core installation device, a battery module, and a mobile power supply, aiming to improve the problem of axial wobbling of the battery core caused by manufacturing tolerances when the battery core is installed in the installation device.

[0006] In a first aspect, the embodiments of this application provide a core installation device for accommodating a battery core. The core installation device includes at least one installation frame. The installation frame includes an end plate, an enclosure, and a first elastic member. The end plate has at least one through hole; the enclosure is connected to the end plate and encloses to form an installation groove communicating with the through hole, and the installation groove is used for installing the end of the battery core; one end of the first elastic member is connected to the hole wall of the through hole, and the first elastic member can undergo elastic deformation so that the first elastic member can elastically abut against the end face of the battery core.

[0007] The mounting frame in the embodiment of the present application is used to accommodate the battery cell, and the mounting frame provides a stable installation environment for the battery cell, wherein the casing is connected to the end plate to enclose a mounting groove connected to the through hole, and the mounting groove is used to accommodate the end of the battery cell, and the casing can provide lateral support for the battery cell. The first elastic member ensures that the battery cell is stably fixed in the mounting groove, reducing the shaking caused by the axial dimensional tolerance. Due to the elastic effect of the first elastic member, the battery cell is subjected to a certain preload in the axial direction, thereby eliminating the gap between the battery cell and the battery cell mounting device in the axial direction.

[0008] The elastic contact between the first elastic member and the end face of the battery cell effectively reduces the axial shaking of the battery cell caused by manufacturing tolerances, and improves the stability of the battery cell in the battery module. Reducing the shaking of the battery cell reduces the impact on the series-parallel metal pole pieces of the two poles of the battery cell, thereby improving the reliability of the battery cell connection and extending the service life of the battery module. Compared with the traditional structural adhesive solution, the design of the first elastic member makes the installation and removal of the battery cell more convenient, facilitates maintenance and rework, and reduces maintenance costs.

[0009] In a second aspect, an embodiment of the present application provides a battery module, comprising a battery cell and a battery cell mounting device as described in the above embodiment; wherein at least one end of the battery cell is mounted in a mounting groove.

[0010] In the embodiment of the present application, by installing the battery cell on the battery cell installation device in the above embodiment, the structural stability of the battery module is significantly improved. The axial shaking of the battery cell is effectively controlled, reducing the instability caused by dimensional tolerances. The battery cell installation device can adapt to battery cells of different sizes, making the battery module more flexible and compatible. This design allows the battery module to be compatible with more than two battery cells with similar axial dimensions, expanding its scope of application. And compared with the traditional structural adhesive solution, the use of the battery cell installation device simplifies the assembly process of the battery module. The installation of the battery cell is easier and faster, reducing assembly time and cost.

[0011] In a third aspect, an embodiment of the present application provides a mobile power supply, comprising a shell, a control board and a battery module as in the above embodiment; wherein the battery module is arranged in the shell, a power supply port is arranged on the shell, and the control board is electrically connected to the battery module and the power supply port respectively.

[0012] In the embodiment of the present application, by installing the battery module in the housing, the overall structure of the mobile power supply is more stable. The axial shaking of the battery module is effectively controlled, thereby improving the stability and reliability of the mobile power supply during use. The flexibility and compatibility of the battery module allow the mobile power supply to adapt to different types of batteries, expanding its application range. This design makes it easier for the mobile power supply to adapt to different devices and usage requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] 200, Battery cell Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application

[0028] Please refer to Figures 1 to 2 , the embodiment of the present application provides a battery cell mounting device 100 for accommodating and fixing a battery cell 200. The battery cell mounting device 100 plays a crucial role in the battery module 1. Its main function is to ensure that the battery cell 200 can be stably placed during the installation process and will not cause the internal battery cell 200 to displace due to vibration, impact or other external factors during use, thereby ensuring the performance and safety of the battery cell 200

[0029] The battery cell mounting device 100 includes a mounting frame 10 for mounting the end of the battery cell 200. The mounting frame 10 can be a plastic frame. The plastic material has a certain elasticity and can absorb and disperse the vibration that may occur during the use of the battery cell 200, reduce the impact on the battery cell 200, and extend its service life. Specifically, the mounting frame 10 is composed of an end plate 11, an enclosure 12 and a first elastic member 13

[0030] It should be noted that in the current battery technology field, the shapes of battery cells 200 are diverse, including but not limited to square battery cells, elliptical battery cells, cylindrical battery cells, etc. The differences in the shapes of these battery cells 200 mainly stem from the differences in their design and manufacturing processes, as well as the performance requirements in different application scenarios. In this embodiment, we take a cylindrical battery cell as an example for detailed description. The cylindrical battery cell is widely used in the battery module 1 and has a certain representativeness

[0031] However, the design concept and fixing mechanism of the battery cell mounting device 100 provided in this application are not limited to cylindrical battery cells. Battery cells 200 with other three-dimensional shapes such as square battery cells and elliptical battery cells can also be fixed using the mounting device in this embodiment. For these battery cells 200 with different shapes, the device can still effectively fix the battery cells 200 by adjusting the shapes and positional layouts of the end plate 11, the surrounding shell 12, and the first elastic member 13.

[0032] Please continue to refer to Figure 2 , in this embodiment, the end plate 11 has at least one through hole 11a. The surrounding shell 12 is connected to the end plate 11 and encloses to form a mounting groove 100a communicating with the through hole 11a. The mounting groove 100a is used to mount the end of the battery cell 200. The surrounding shell 12 provides support on the outer peripheral wall of the battery cell 200, which helps to disperse the external pressure received by the battery cell 200, enhances the mechanical stability of the battery cell 200, and can also limit the battery cell 200 to ensure that the battery cell 200 does not shift circumferentially within the mounting groove 100a, thereby maintaining the accurate position of the battery cell 200 within the mounting groove 100a. During the actual installation process, the battery cell 200 is inserted into the mounting groove 100a through the notch of the mounting groove 100a. The design of the through hole 11a ensures that the positive and / or negative electrodes at the end of the battery cell 200 are visible and accessible within the mounting groove 100a, facilitating the electrical connection of the battery cell 200.

[0033] In this embodiment, the end plate 11 and the surrounding shell 12 are an integral member. The integral design enhances the structural stability of the mounting frame 10 and reduces the misalignment or deformation that may occur during the assembly process. The integrated structure of the end plate 11 and the surrounding shell 12 can provide better mechanical support and enhance the shock resistance and deformation resistance of the entire battery cell mounting device 100. In other embodiments, the end plate 11 and the surrounding shell 12 can also be a split structure fixed together.

[0034] Such as Figure 2As shown, one end of the first elastic member 13 is connected to the hole wall of the through hole 11a, and the other end of the first elastic member 13 can be suspended in the through hole 11a. The suspended state can provide a better damping effect, and the first elastic member 13 can absorb the vibration of the battery cell 200 during installation or use. The other end of the first elastic member 13 can also be connected to the hole wall of the through hole 11a or to the end plate 11, which can provide a more stable support for the first elastic member 13, limit the movement range of the first elastic member 13, and ensure the fixation of the battery cell 200 in the installation groove 100a. There is a gap between the first elastic member 13 and the through hole 11a to enable the first elastic member 13 to undergo elastic deformation so that the first elastic member 13 can elastically abut against the end face of the battery cell 200. Through the elastic abutment between the first elastic member 13 and the end face of the battery cell 200, the axial wobbling of the battery cell 200 in the installation groove 100a caused by manufacturing tolerances can be effectively reduced, and the stability of the battery cell 200 in the battery cell installation device 100 is improved. The first elastic member 13 also provides additional shock protection, reduces the impact on the series-parallel metal pole pieces at both poles of the battery cell 200, thereby improving the reliability of the connection of the battery cell 200 and extending the service life of the battery module 1. And compared with the traditional structural adhesive scheme, the design of the first elastic member 13 makes the installation and disassembly of the battery cell 200 more convenient, facilitates maintenance and rework, and reduces the maintenance cost.

[0035] Further, the first elastic member 13 enables the battery cell installation device 100 to be compatible with two or more battery cells 200 with similar axial dimensions, enhancing the versatility and flexibility of the battery cell installation device 100.

[0036] In some embodiments, a plurality of first elastic members 13 are provided, and the plurality of first elastic members 13 are arranged at intervals along the circumferential direction of the through hole 11a. The first elastic members 13 arranged at intervals help to disperse the stress that may be generated during the installation of the battery cell 200, reduce the local pressure on the battery cell 200, and thus protect the battery cell 200 from damage. Through the synergistic effect of the plurality of first elastic members 13, the axial position of the battery cell 200 in the installation groove 100a is more stable. The plurality of elastic members define an opening 13a for exposing the end face of the battery cell 200, so that more of the positive and / or negative electrodes of the battery cell 200 are exposed and are easy to contact, simplifying the electrical connection process between the battery cell 200 and the external circuit.

[0037] As Figure 5 shown, in some embodiments, two first elastic members 13 are provided, and the two first elastic members 13 are centrosymmetric about the central axis of the through hole 11a, providing uniform and balanced support for the battery cell 200, reducing the stress unevenness caused by improper installation, and thus protecting the battery cell 200 from damage.

[0038] In some embodiments, the end plate 11 and the first elastic member 13 are an integral component, reducing potential failure points at the connection between the first elastic member 13 and the end plate 11, lowering the risk of failure during the use of the mounting frame 10, and enhancing safety. Without additional materials, simply relying on the mounting frame 10 itself can effectively control the axial wobbling of the battery cell 200, and the production is simple. In other embodiments, the end plate 11 and the first elastic member 13 may be separate components fixed together.

[0039] As Figure 3 shown, in some embodiments, the end plate 11 is connected to a plurality of enclosures 12, meaning that a plurality of independent mounting slots 100a can be formed on one end plate 11. Each mounting slot 100a can separately accommodate a battery cell 200, thereby allowing multiple battery cells 200 to be installed in one mounting device. The user can increase or decrease the number of mounting slots 100a according to needs, flexibly adapting to different combinations of battery cells 200 and energy storage requirements.

[0040] As Figure 6 shown, wherein, the battery cell mounting device 100 includes at least one mounting frame 10. When only one mounting frame 10 is provided in the battery cell mounting device 100, this design allows one end of the battery cell 200 to be mounted in a fixed frame and the other end to be mounted in the mounting frame 10, and the fixed frame and the mounting frame 10 are connected to each other. The mounting frame 10 axially presses the battery cell 200 against the fixed frame through the first elastic member 13, ensuring the stability and axial consistency of the battery cell 200 during installation. This single-end fixing method is suitable for scenarios with limited space or specific installation requirements. When two mounting frames 10 are provided in the battery cell mounting device 100, the two mounting frames 10 are arranged opposite to each other and can be connected to each other, and are used to cooperate in mounting both ends of the battery cell 200. This design allows both ends of the battery cell 200 to be mounted in the mounting frames 10, and the two first elastic members 13 of the two mounting frames 10 cooperate with each other to be able to axially press the battery cell 200, ensuring that the battery cell 200 is uniformly stressed throughout its length and reducing stress concentration caused by improper installation. This double-end fixing method provides higher stability and adaptability.

[0041] As Figure 3 and Figure 4As shown, in some embodiments, the battery cell mounting device 100 further includes a fixing member 15. The fixing member 15 is connected to the end plate 11 and extends along the axial direction. In this embodiment, the fixing member 15 is in the shape of an elongated cylinder. The fixing member 15 of one mounting frame 10 is detachably connected to the fixing member 15 of another mounting frame 10, providing convenience during installation and maintenance, and making the installation and disassembly of the battery cell 200 in the battery cell mounting device 100 more convenient. Along the axial direction of the fixing member 15, a reinforcing rib 16 is further provided. The reinforcing rib 16 is connected to the fixing member 15 and is used to strengthen the support structure of the fixing member 15. The reinforcing rib 16 can provide additional mechanical support, enhance the strength of the fixing member 15, and reduce deformation or damage caused by stress. The reinforcing rib 16 helps the fixing member 15 to more stably fix the battery module 1 and reduces the movement or vibration of the mounting frame 10 during use.

[0042] As Figure 5 、 Figure 6 and Figure 7 shown, in some embodiments, the fixing member 15 is provided with a connection hole 15a. The connection hole 15a penetrates the end plate 11. The fixing members 15 of the two mounting frames 10 can also be fixed by locking screws 151 into the connection hole 15a. This fixing method provides better stability and is suitable for scenarios that require higher-strength fixing.

[0043] In some embodiments, the two mounting frames 10 can also be fixed by clamping the fixing member 15 of one mounting frame 10 with the fixing member 15 of another mounting frame 10. This connection method simplifies the installation process and improves the installation efficiency.

[0044] Please continue to refer to Figure 7 , in some embodiments, the fixing member 15 is located between two adjacent enclosures 12. The space between the enclosures 12 can be utilized to arrange the fixing member 15, which can more effectively utilize the limited space, especially in the design of a compact battery module 1. And it helps to accurately control the installation positions of the two mounting frames 10 to ensure the correct alignment of the battery cells 200. Of course, the fixing member 15 can also be arranged around the end plate 11, and the present application does not make any limitation thereto.

[0045] As Figure 7 and Figure 8As shown, in some embodiments, the first elastic member 13 includes a first connection section 131 and a first extension section 132. The first connection section 131 is connected to the wall of the through hole 11a, providing a fixed point for the first elastic member 13 to ensure its stable fixation within the installation groove 100a. As the connection part between the first elastic member 13 and the end plate 11, it transmits the supporting force of the battery cell 200. The first extension section 132 is connected to the first connection section 131 and extends circumferentially along the wall of the through hole 11a with a gap therebetween. The first extension section 132 can provide elastic support, allowing the first elastic member 13 to have a certain degree of movement in the axial direction of the installation groove 100a without excessive movement.

[0046] As Figure 8 and Figure 9 As shown, the first elastic member 13 further includes a first convex section 133. The first convex section 133 is connected to one end of the first extension section 132 away from the first connection section 131 and protrudes towards the inside of the installation groove 100a relative to the first extension section 132. If the axial dimension of the battery cell 200 is small, the first convex section has a first abutting surface 1331, and the first abutting surface 1331 can abut against the axial end surface of the battery cell 200. If the axial dimension of the battery cell 200 is large, after the first abutting surface 1331 of the first convex section 133 abuts against the end surface of the battery cell 200, through the elastic force of the first elastic member 13, it can move in a direction away from the notch of the installation groove 100a to adapt to the battery cell 200 with a larger axial dimension. Through the design of the first convex section 133, the battery cell installation device 100 can adapt to battery cells 200 with different axial dimensions, enhancing its versatility and flexibility. The first convex section 133 can tightly abut against the end surface of the battery cell 200, ensuring the stable fixation of the battery cell 200 in the axial direction within the installation groove 100a and reducing shaking, regardless of whether the axial dimension of the battery cell 200 is small or large.

[0047] In some embodiments, the first extension section 132 and the first convex section 133 are combined into an arc section, making the shape of the opening 13a exposing the positive and / or negative poles of the end surface of the battery cell 200 regular. Moreover, the design of the arc section reduces the stress of the material in the stress concentration area, thereby reducing the risk of material fatigue and fracture.

[0048] Please continue to refer to Figure 9 , in some embodiments, the surface of the connection between the first extension section 132 and the first convex section 133 facing the installation groove 100a is a smooth surface and / or the surface of the connection between the first convex section 133 and the first guiding section 134 facing the installation groove 100a is a smooth surface, avoiding damage to the outer shell of the battery cell 200 caused by the uneven surface of the first elastic member 13 in contact with the battery cell 200, reducing the risk of short circuit or liquid leakage of the battery cell 200 within the installation groove 100a, and improving the overall safety.

[0049] Please continue to refer to Figure 9 , in some embodiments, the first elastic member 13 further includes a first guiding section 134, which is connected to one end of the first protruding section 133 away from the first extending section 132. The first guiding section 134 and the first extending section 132 are in the same plane. The first guiding section 134 enhances the structural stability of the first elastic member 13, helps to maintain the shape and position of the first protruding section, and reduces deformation during use. The first guiding section 134 can ensure the rebound effect of the first protruding section after use through the synergistic effect with the first extending section 132.

[0050] As Figure 8 and Figure 9 shown, to solve the problem of the shaking of the battery cell 200 caused by the manufacturing tolerance in the radial direction in the installation groove 100a, the first notch 100b and the second notch 100c are arranged at intervals on the groove side wall of the installation groove 100a. It can be understood that the first notch 100b and the second notch 100c do not penetrate from the groove side wall to the groove bottom wall. The groove side wall of the installation groove 100a between the first notch 100b and the second notch 100c forms the second elastic member 14. The arrangement of the first notch 100b and the second notch 100c allows the second elastic member 14 to have a certain movement space in the radial direction of the installation groove 100a, but not to move excessively. The groove side wall without the first notch 100b and the second notch 100c can provide necessary support for the second elastic member 14. The second elastic member 14 is used to elastically abut against the outer peripheral surface of the battery cell 200. The elastic force of the second elastic member 14 can adapt to the radial dimension change of the battery cell 200, helps to reduce the radial shaking of the battery cell 200 in the installation groove 100a, and ensures that the battery cell 200 is stably fixed in the installation groove 100a.

[0051] In some embodiments, the enclosure 12 and the second elastic member 14 are an integral component, reducing potential failure points at the connection part, reducing the risk of displacement or short circuit of the battery cell 200 in the installation groove 100a, and can more effectively fix the battery cell 200. Without additional materials, relying on the installation frame 10 itself, it can effectively control the shaking of the battery cell 200 in the radial direction, and the production is simple. In other embodiments, the enclosure 12 and the second elastic member 14 can be separate components fixed together.

[0052] As Figure 9As shown, in some embodiments, the second elastic member 14 includes a second extension section 141 and a second convex section 142. The second extension section 141 provides a fixed point for the second elastic member 14 to ensure the stable position of the second elastic member 14. The second extension section 141 extends away from the through hole 11a. The second convex section 142 is connected to one end of the second extension section 141 away from the through hole 11a. The second extension section 141 can provide elastic support for the second convex section 142 and protrudes into the mounting groove 100a relative to the second extension section 141. The second convex section has a second abutting surface 1421, and the second abutting surface 1421 is used to abut against the battery cell 200. When the radial dimension of the battery cell 200 is relatively large, through the elastic force of the second elastic member 14, it can move in the radial direction away from the mounting groove 100a to adapt to the battery cell 200 with a larger radial dimension.

[0053] Combined with the above setting of the first elastic member 13, the battery cell mounting device 100 of this embodiment can adapt to battery cells 200 of different specifications and sizes. In the case of small differences, by designing different elastic return strokes of the first elastic member 13 and the second elastic member 14, the same set of mounting frames 10 can be made to be compatible with multiple models of battery cells 200. Thereby reducing the design and development costs and enhancing the product supply guarantee ability.

[0054] Please continue to refer to Figure 9 , in some embodiments, the second elastic member 14 further includes a second guiding section 143. The second guiding section 143 is connected to one end of the second convex section 142 away from the second extension section 141. The connection between the second guiding section 143 and the second convex section 142 is an inclined structure that gradually extends obliquely towards the bottom wall of the mounting groove 100a. The inclined structure design of the second guiding section 143 helps to accurately guide the battery cell 200 to move along a predetermined direction when the battery cell 200 is inserted into the mounting groove 100a, reducing the installation error. Making the installation operation of the battery cell 200 more intuitive and easier, improving the installation efficiency. It helps to ensure the correct position of the battery cell 200 in the mounting groove 100a and improve the positioning accuracy of the battery cell 200.

[0055] Understandably, the surface of the connection between the second extension section 141 and the second protruding section 142 of the second elastic member 14 facing the mounting groove 100a is a smooth surface and / or the surface of the connection between the second protruding section 142 and the second guide section 143 facing the mounting groove 100a is a smooth surface. The setting of the smooth surface reduces the mechanical scratches or wear that may be caused to the outer surface of the battery cell 200 when the battery cell 200 is inserted, and protects the integrity of the battery cell 200. It avoids damage to the outer shell of the battery cell 200 caused by the uneven surface of the second elastic member 14, reduces the risk of short circuit or leakage of the battery cell 200 in the mounting groove 100a, and improves overall safety. The smooth connection surface also makes the process of inserting the battery cell 200 into the mounting groove 100a smoother, improves the operating experience, and reduces the difficulty of operation.

[0056] like Figure 8 As shown, in some embodiments, a plurality of second elastic members 14 are provided, and the plurality of second elastic members 14 are arranged at intervals along the circumference of the mounting groove 100a. The multi-point support helps to fix the battery cell 200 more stably, reduce the shaking caused by dimensional tolerance or external impact, and improve the stability of the battery cell 200. The plurality of elastic members can more effectively absorb and disperse the vibration that may be generated by the battery cell 200 during use, reduce the impact on the battery cell 200, and extend the service life of the battery cell 200. Furthermore, the plurality of second elastic members 14 are evenly spaced and arranged, which can provide uniform support for the outer peripheral wall of the battery cell 200, reduce local stress concentration, and protect the battery cell 200 from damage.

[0057] like Figure 1 and Figure 2 As shown, the embodiment of the present application further provides a battery module 1, including a battery cell 200 and a battery cell installation device 100 as described in any of the above embodiments, wherein at least one end of the battery cell 200 is installed in the installation groove 100a. By installing at least one end of the battery cell 200 in the installation groove 100a, the stability of the battery cell 200 in the battery module 1 is enhanced, and the shaking and displacement during transportation and use are reduced.
