Description

Technical Field

[0001] This application relates to the field of energy storage equipment technology, and in particular to a quick-lock connection structure and energy storage equipment. Background Technology

[0002] With the rapid development of battery technology, especially the widespread application of modular battery stacking technology in battery energy storage systems and electric vehicles, improving the assembly and unlocking efficiency of battery module stacking has become an important research direction. Existing stacking module technologies mainly rely on traditional side bolts or metal interlocking plates to fix and connect the modules.

[0003] Traditional side-bolt fixing requires operators to align each bolt hole on the module's sidewall and tighten it with tools. This cumbersome installation process is not only time-consuming and labor-intensive but also severely restricts production efficiency. While metal interlocking locking simplifies the connection process to some extent, it still relies on specialized tools and skilled operators. Both connection methods share the pain point of difficult maintenance and repair. When a specific module needs to be replaced, it is often necessary to disassemble multiple adjacent modules, significantly extending system downtime.

[0004] In terms of structural design, existing connection methods require reserved space for bolts or metal connectors, forcing an increase in the overall module size. This contradicts the current trend of miniaturization and high energy density in battery systems. More importantly, these traditional connection structures are limited to unlocking from the locking direction, making them ineffective in scenarios requiring integrated locking and unlocking. Especially in applications with limited space or frequent operations, traditional connection unlocking methods cannot meet the requirements of efficiency and convenience. Utility Model Content

[0005] In order to simultaneously meet the requirements of rapid installation, efficient unlocking and reliable connection, and to adapt to the development needs of current battery modular stacking technology, this application provides a quick-lock connection structure and energy storage device.

[0006] The quick-lock connection structure and energy storage device provided in this application adopt the following technical solution: A quick-lock connection structure, comprising: The first connector includes a locking tongue and an unlocking part; The second connector includes a locking hook portion; The first connector and the second connector are movable relative to each other and are self-locked by engaging the locking tongue and the locking hook. The unlocking part can drive the locking tongue to move to unlock, and the unlocking direction is perpendicular to the self-locking direction.

[0007] By adopting the above technical solution, the quick-lock connection structure of this application simplifies the operation process in traditional connection methods through its self-locking design, eliminating the need for complex bolt tightening or metal plate fixing, greatly improving installation efficiency, and meeting the requirements of rapid assembly. At the same time, through the self-locking function of the locking tongue and locking hook, a stable connection can be formed between the connecting parts. In addition, the normal direction design of the unlocking process makes the operation simpler, not only improving disassembly efficiency, but also making the unlocking process free of complicated steps or tools. Operators can complete the unlocking in a short time, ensuring efficient maintenance and replacement.

[0008] In one specific implementation, the latch portion is provided with a first inclined surface, and the hook portion is provided with a second inclined surface that matches the first inclined surface, and the first inclined surface and the second inclined surface are in slidable contact.

[0009] By adopting the above technical solution, the sliding contact between the first and second inclined surfaces can reduce the impact force generated during the connection process, making the docking process between the latch and the hook more stable, avoiding jamming caused by direct contact, and improving the smoothness of the connection.

[0010] In one specific implementation, the locking hook portion is provided with a locking plane, and the locking tongue portion is provided with a latching plane that abuts against and engages with the locking plane.

[0011] By adopting the above technical solution, the latching plane of the latch and the locking plane of the hook can be engaged to ensure that the two parts are firmly fixed after connection, increase the stability and anti-loosening of the connection, and prevent the first and second connecting parts from accidentally separating during use.

[0012] In one specific implementation, the locking surface and / or the engaging surface are provided with anti-slip textures.

[0013] By adopting the above technical solution and utilizing the anti-slip texture design, the friction between the locking plane and the fastening plane can be enhanced, making the connection more stable and less prone to loosening or slippage due to external forces.

[0014] In one specific implementation, the inclination angle of the first inclined plane is greater than or equal to the inclination angle of the second inclined plane.

[0015] By adopting the above technical solution, when the inclination angle of the first inclined surface is greater than or equal to that of the second inclined surface, the locking tongue and the locking hook will more easily generate a self-locking effect during the fastening process; the larger angle of the first inclined surface can better guide the locking hook into the locking tongue, improve the accuracy of the connection, ensure that the two are tightly fastened, and thus enhance the stability after the connection.

[0016] In one specific implementation, a spring element is also included for supporting the second connector.

[0017] By adopting the above technical solution, the spring component continuously applies appropriate force to the second connector to keep the second connector in a proper position, ensuring that the connection system is stable and firm. Especially when the connector is used for a long time or subjected to external impact, the elasticity of the spring component can prevent the connection from loosening and maintain the connection stability.

[0018] An energy storage device includes a plurality of energy storage modules and a quick-lock connection structure as described in any of the above claims, wherein two adjacent energy storage modules are detachably connected via the quick-lock connection structure.

[0019] By adopting the above technical solution, the quick-lock connection structure makes the installation and disassembly of energy storage modules more convenient. Operators only need to perform simple docking and unlocking actions to complete the connection and disassembly of energy storage modules, which can also reduce the reliance on professional tools and external assistance, thereby improving the maintenance efficiency and ease of use of energy storage equipment. At the same time, the quick-lock connection structure can also enhance the connection stability between adjacent energy storage modules, prevent the modules from loosening or falling off due to vibration or external force, and ensure the installation of energy storage equipment.

[0020] In one specific implementation, the first connector and the second connector are respectively located at the top and bottom of the energy storage module.

[0021] By adopting the above technical solution, the first connector and the second connector are respectively located at the top and bottom of the energy storage module, so that multiple energy storage modules can be tightly stacked and securely connected. This design allows the system to be flexibly expanded to meet different capacity requirements.

[0022] In one specific implementation, the first connector and / or the second connector are detachably mounted on the energy storage module.

[0023] By adopting the above technical solution, the detachable connector design allows for rapid replacement in case of failure; and the connector is reusable, avoiding the need to purchase new connectors every time the energy storage module is replaced, thereby reducing the cost of equipment maintenance and module replacement.

[0024] In summary, the beneficial technical effects of this application are as follows: The quick-lock connection structure of this application simplifies the operation process in traditional connection methods through innovative self-locking design, avoids complex bolt tightening or metal joint fixing, significantly improves installation efficiency, and meets the needs of rapid assembly; the self-locking function ensures a stable connection between the connecting parts, while the unlocking process, through the normal unlocking design perpendicular to the self-locking direction, makes disassembly more convenient, without complicated steps or tools. This structure is particularly suitable for scenarios that require frequent assembly and disassembly, such as energy storage equipment, improving the maintenance efficiency and ease of use of the equipment; In addition, the quick-lock connection structure effectively reduces the impact force during the connection process and avoids jamming through the precise fit between the latch and the hook and the sliding contact between the first and second inclined surfaces. The engagement plane of the latch and the hook abuts against the locking plane to ensure the stability and anti-loosening of the connection. The addition of the spring further enhances the stability of the connection and prevents the connecting parts from loosening. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] Example 1 Reference Figure 1-3This application discloses a quick-lock connection structure and an energy storage device. In this embodiment, the energy storage device includes a plurality of energy storage modules 7. In this embodiment, the energy storage module 7 includes a housing 8 and an energy storage element disposed in the housing 8. The plurality of energy storage modules 7 are stacked and assembled in a vertical direction. The housings 8 of two adjacent energy storage modules 7 are detachably connected by a quick-lock connection structure 1.

[0031] The quick-lock connection structure 1 includes a first connector 2 and a second connector 3. In this embodiment, the top and bottom of the housing 8 of the energy storage module 7 are respectively provided with a first cavity 81 and a second cavity 82 for accommodating the first connector 2 and the second connector 3, and the first cavity 81 and the second cavity 82 are connected to the outside. The first connector 2 and / or the second connector 3 are detachably mounted on the energy storage module 7. In this embodiment, the first connector 2 includes a connecting part 23, and the second connector 3 includes a fixing part 32. The first connector 2 is detachably mounted in the first cavity 81 of the energy storage module 7 housing 8 via the connecting part 23. In this embodiment, the first cavity 81 is provided with an installation part 83. The connecting part 23 of the first connector 2 is mounted on the installation part 83 via a bolt 5. The bolt 5 passes through the installation part 83 and exits the connecting part 23. One end of the bolt 5 that exits the connecting part 23 is threadedly connected to a nut 6. The second connector 3 is mounted in the second cavity 82 of the energy storage module 7 housing 8 via the fixing part 32. The fixing part 32 of the second connector 3 is integrally formed in the second cavity 82.

[0032] In this embodiment, both the first connector 2 and the second connector 3 are vertically arranged. The first connector 2 also includes a locking tongue 21 and an unlocking part 22. In this embodiment, the connecting part 23 of the first connector 2 extends outward from the first cavity 81 and is connected to the locking tongue 21 and the unlocking part 22. The locking tongue 21 is an elastic structure. The second connector 3 also includes a locking hook 31. The fixing part 32 and the locking hook 31 are integrally formed to form the second connector 3. Both the locking hook 31 and the fixing part 32 are elastic structures. In this embodiment, the elastic structure of the locking tongue 21 and the locking hook 31 includes, but is not limited to, being made of materials such as stainless steel, carbon steel, titanium alloy, plastic, or rubber. In practice, materials with appropriate strength, corrosion resistance, and elastic recovery ability can be selected according to requirements to ensure the stability and reliability of the fastening between the first connector 2 and the second connector 3.

[0033] When the housings 8 of two energy storage modules 7 are stacked and assembled, the first connector 2 and the second connector 3 of two adjacent energy storage modules 7 move relative to each other in the vertical direction and are locked together by the locking tongue 21 and the locking hook 31 to form a self-locking mechanism. In the specific installation process, the operator stacks and assembles the housings 8 of the energy storage modules 7. As the housings 8 of the energy storage modules 7 move, the first cavity 81 and the second cavity 82 of two adjacent energy storage modules 7 are connected, which drives the first connector 2 and the second connector 3 to move relative to each other and connect. During connection, the first connector 2 is inserted into the second cavity 82 of the adjacent energy storage module 7, and the locking tongue 21 on the first connector 2 and the locking hook 31 on the second connector 3 are tightly connected to form a stable self-locking state. This process simplifies the complex steps in the traditional connection method, avoids the tightening of bolts 5 or the fixing of metal connecting pieces, and significantly improves the installation efficiency.

[0034] When unlocking is required, the unlocking part 22 on the first connector 2 can be moved, and the unlocking part 22 can drive the locking tongue 21 to move in the horizontal direction to achieve unlocking; in this embodiment, the self-locking direction between the first connector 2 and the second connector 3 is the vertical direction, the unlocking direction between the first connector 2 and the second connector 3 is the horizontal direction, the unlocking direction is perpendicular to the self-locking direction, and the unlocking direction is the normal direction of the self-locking direction; During the disassembly process, the operator moves the unlocking part 22 on the first connector 2. The unlocking part 22 drives the locking tongue 21 to move, releasing the latching tongue 21 from the locking hook 31. Since the unlocking direction of the unlocking part 22 is perpendicular to the self-locking direction, the user only needs to apply force in the normal direction perpendicular to the self-locking direction to easily unlock the connection between the first connector 2 and the second connector 3. This design makes the disassembly operation simpler and more efficient. The operator can quickly complete the unlocking without complicated steps or tools.

[0035] In this embodiment, the latch portion 21 is provided with a first inclined surface 24, and the hook portion 31 is provided with a second inclined surface 33 that matches the first inclined surface 24. Through the sliding contact between the first inclined surface 24 and the second inclined surface 33, the relative movement between the first connector 2 and the second connector 3 can be carried out smoothly. The sliding contact between the first inclined surface 24 and the second inclined surface 33 can reduce the impact force generated during the connection process, so that the two gradually approach each other until the hook portion 31 and the latch portion 21 are fully engaged, forming a stable self-locking connection. This structure helps to avoid jamming caused by direct contact and improves the smoothness of the connection process.

[0036] Furthermore, the inclination angle of the first inclined surface 24 is greater than or equal to the inclination angle of the second inclined surface 33. In this embodiment, the inclination angle of the first inclined surface 24 is slightly larger than the inclination angle of the second inclined surface 33 by 0-5°. When the two components come into contact, the first inclined surface 24 contacts the second inclined surface 33 earlier and begins to slide, thereby making the connection process smoother, reducing jamming or impact caused by sudden contact, and ensuring smooth operation. This design also makes it easier for the locking tongue 21 and the locking hook 31 to generate a self-locking effect during the latching process, which helps to make the first inclined surface 24 and the second inclined surface 33 fit tightly, thereby optimizing the latching of the locking tongue 21 and the locking hook 31, making the connection more secure, and ensuring the efficiency and safety of the connection.

[0037] In this embodiment, the locking hook portion 31 is provided with a locking plane 34, and the locking tongue portion 21 is provided with a fastening plane 25 that abuts against the locking plane 34. When the first connecting member 2 and the second connecting member 3 are connected, the fastening plane 25 of the locking tongue portion 21 and the locking plane 34 of the locking hook portion 31 gradually come into contact and tightly abut against each other. When the connecting members are fully closed, a stable locking state is formed between the locking tongue portion 21 and the locking hook portion 31, ensuring a firm connection. Through this design, the connected components can be firmly fixed to prevent accidental detachment during subsequent use.

[0038] The implementation principle of this application embodiment is as follows: During the assembly of the energy storage device, the operator stacks the housings 8 of several energy storage modules 7. Through the movement of the housings 8 of the energy storage modules 7, the first cavity 81 and the second cavity 82 of two adjacent energy storage modules 7 gradually connect, causing the first connector 2 and the second connector 3 of the energy storage modules 7 to move relative to each other in the vertical direction and connect. At this time, the first connector 2 is inserted into the second cavity 82 of the adjacent energy storage module 7 in the vertical direction, and the first inclined surface 24 on the locking tongue 21 and the first inclined surface 24 on the locking hook 31 connect with the first inclined surface 24 on the locking hook 31. The second inclined surface 33 begins to interact through sliding contact. When the first connector 2 and the second connector 3 move relative to each other, the mutual squeezing action between the first inclined surface 24 and the second inclined surface 33 causes them to gradually approach each other. The latching plane 25 of the latch 21 and the locking plane 34 of the hook 31 begin to contact and gradually abut. When the connector is fully closed, the latching plane 25 of the latch 21 and the locking plane 34 of the hook 31 fit tightly together. The hook 31 and the latch 21 are fully engaged, forming a stable locking state and ensuring the firmness of the connection. When maintenance or replacement of the energy storage device is required, the corresponding energy storage module 7 is disassembled. The operator moves the unlocking part 22 on the first connector 2 horizontally. The unlocking part 22 drives the locking tongue 21 to move horizontally, releasing the latching tongue 21 from the locking hook 31. During this process, since the unlocking direction of the unlocking part 22 is perpendicular to the self-locking direction, the user only needs to apply force in the normal direction perpendicular to the self-locking direction to easily unlock the device, thus conveniently and quickly unlocking the first connector 2 and the second connector 3. After unlocking, the corresponding energy storage module 7 can be removed for maintenance or replacement by moving the housing 8 of the energy storage module 7, thereby ensuring efficient maintenance and replacement of the energy storage device.

[0039] This embodiment provides a highly efficient quick-lock connection structure 1 for modular stacking of energy storage devices, significantly simplifying the assembly and disassembly process of energy storage modules 7. The quick-lock connection structure 1, through the self-locking design of the first connector 2 and the second connector 3, avoids the complex bolt tightening or metal plate fixing steps of traditional connection methods, improving installation efficiency. The first connector 2 and the second connector 3 form a stable self-locking mechanism through the cooperation of the locking tongue 21 and the locking hook 31, ensuring the robustness of the module connection. Furthermore, the inclined surface design of the quick-lock connection structure 1 reduces impact during the connection process, ensuring smooth docking between the first connector 2 and the second connector 3 and improving operational smoothness. The design of the locking plane 34 and the latching plane 25 ensures the stability of the first connector 2 and the second connector 3, preventing accidental detachment during use. When equipment maintenance or module replacement is required, operators can easily disassemble the module through a simple unlocking operation. Disassembly can be easily achieved simply by moving the unlocking part 22 on the first connector 2. The normal direction design of the unlocking process makes the operation simpler, which not only improves the disassembly efficiency, but also makes the unlocking process unnecessary for complicated steps or tools. Operators can complete the unlocking in a short time, ensuring efficient maintenance and replacement, thereby improving the maintenance and replacement efficiency of energy storage equipment and ensuring the efficient operation of the equipment.

[0040] Example 2 Reference Figure 4 The difference between this embodiment and the first embodiment is that the quick-lock connection structure 1 also includes a spring member 4. The spring member 4 is used to abut against the second connector 3. In this embodiment, the spring member 4 is disposed in the second cavity 82 of the energy storage module 7 housing 8. The second cavity 82 is provided with abutting part 84. One end of the spring member 4 abuts against the abutting part 84 in the second cavity 82, and the other end abuts against the fixing part 32 of the second connector 3.

[0041] When the quick-lock structure is locked, the spring 4 is used to continuously apply appropriate force to the second connector 3, providing the second connector 3 with anti-unlock capability, keeping the second connector 3 in the proper position, thereby ensuring a stable connection between the first connector 2 and the second connector 3, and ensuring the stability of the stacked assembly of the energy storage module 7. After the energy storage module 7 is subjected to external impact or long-term use, the spring component 4 can effectively prevent the loosening between the first connector 2 and the second connector 3, ensuring the stability of the connection, thereby improving the durability of the first connector 2 and the second connector 3, and thus ensuring the long-term stability of the energy storage device connection system.

[0042] Example 3 The difference between this embodiment and embodiment one is that, in the quick-lock connection structure 1, the locking plane 34 and / or the engaging plane 25 are provided with anti-slip textures (not shown in the figure); the overall structure of embodiment three is largely the same as that of embodiment one, and the specific structure can be found in the appendix. Figure 1-3 ; In this embodiment, in order to enhance the stability of the connection, both the locking plane 34 and the fastening plane 25 are provided with anti-slip textures. The anti-slip textures can increase the friction between the locking plane 34 and the fastening plane 25, making the connector less likely to loosen or slip under external force, thereby improving the stability and safety of the connection.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
