Description

Technical Field

[0001] This application relates to the field of energy storage batteries, and more specifically, to a protective box and a reusable energy storage battery pack. Background Technology

[0002] A battery storage pack is a device used to store and release electrical energy. It consists of multiple battery cells connected in series, parallel, or a series-parallel combination to meet specific voltage, capacity, and power requirements. With the rapid development of the electric vehicle industry, the retirement rate of power batteries is accelerating. Although retired power batteries experience performance degradation, they still possess a certain energy storage capacity. To effectively utilize these retired battery resources and encourage the technological recycling of power batteries, a "cascade utilization" strategy is currently widely adopted. This involves selecting battery cells or modules with better performance and reusing them in other fields.

[0003] Currently, mainstream battery packs are fixed to the battery box or support frame with bolts. When disassembling and recycling a battery cell or module, tools are needed to remove the bolts one by one. The whole process is time-consuming, labor-intensive, inefficient, and prone to damage. Summary of the Invention

[0021] Furthermore, the protective box includes a linear drive component, which is installed on the top of the protective box body. The drive end of the linear drive component extends into the protective box body and is connected to the movable frame in a transmission manner to drive the movable frame to move up and down in the vertical direction.

[0022] Furthermore, the movable component also includes a support frame and a roller, the support frame being connected to the movable frame and having a roller mounted on top, the roller's axis being perpendicular to the axis of the inlet and outlet;

[0023] The partition is provided with a receiving groove opposite to the roller, and the roller can protrude through the receiving groove from the upper surface of the partition to abut against the energy storage battery body.

[0024] Furthermore, the linear drive component is connected to the movable frame via a support frame;

[0025] The support frame includes a connecting arm and two transmission arms. The two ends of the connecting arm are perpendicularly connected to the two transmission arms, and the two transmission arms are located on the same side of the connecting arm.

[0026] The connecting arm is connected to the linear drive member, and both of the transmission arms extend into the openings of the multiple movable frames.

[0027] Furthermore, the movable component includes multiple movable frames, which are spaced apart and slide in a one-to-one correspondence with the multiple partitions;

[0028] The axes of the receiving areas formed by the enclosure between each of the movable frames and the partition are collinear.

[0029] Furthermore, in two adjacent movable frames, the two free ends located on the same side are connected by a connecting rod; the support frame is perpendicularly connected to the connecting rod.

[0030] Furthermore, the protective box includes a positioning seat, which is mounted on the upper surface of the partition and cooperates with the partition to form a positioning area for engaging with the bottom of the energy storage battery body.

[0036] The two free ends of the movable frame slide against the partition, allowing it to rise and fall vertically. When placing or removing the energy storage battery body, the movable frame is first raised, then the energy storage battery body is placed on the partition, and finally the movable frame is lowered to fix the position of the energy storage battery body. After fixing the energy storage battery body, the movable frame, under its own weight, keeps the closed end in contact with the top of the energy storage battery body, and the two sides of the movable frame can limit the movement of the energy storage battery body, thus achieving a fixing and limiting function for the energy storage battery body.

[0052] Example 1

[0053] A battery storage pack is a device used to store and release electrical energy. It consists of multiple battery cells connected together in series, parallel, or series-parallel combinations to meet specific voltage, capacity, and power requirements. With the rapid development of the electric vehicle industry, the retirement rate of power batteries is accelerating. Although retired power batteries experience performance degradation, they still possess a certain energy storage capacity. To effectively utilize these retired battery resources and encourage the technological recycling of power batteries, a "cascade utilization" strategy is currently widely adopted. This involves selecting battery cells or modules with better performance and reusing them in other fields. Currently, mainstream battery packs are bolted to battery boxes or support frames. When disassembling and recycling a battery cell or module, tools are needed to remove each bolt individually, a time-consuming, labor-intensive, inefficient process that can easily cause damage.

[0054] In view of this, see Figures 1 to 8 The protective box provided in this embodiment of the invention is used to accommodate the energy storage battery body 4, including a protective box body 1, a movable door 18, and a movable component; a partition 2 for supporting the energy storage battery body is installed inside the protective box body 1, and the protective box body 1 is also provided with an inlet and outlet for the energy storage battery body to enter, and the movable door 18 is movably connected to the inlet and outlet; the movable component includes a movable frame 5 that can be raised and lowered in the vertical direction, and the movable frame 5 has an opening facing the partition 2; both free ends of the movable frame 5 are slidably engaged with the partition 2; in the vertical direction, the closed end of the movable frame 5 is located above the partition 2, and together with the partition 2, they enclose a accommodating area for accommodating the energy storage battery body 4, and the movable frame 5 cooperates with the partition 2 to limit or unlock the energy storage battery body.

[0055] Specifically, see Figure 1 The protective box body 1 has a hinged door 18 on its front, and a latch lock 19 is provided between the door 18 and the protective box body 1. By releasing the latch lock 19, the door 18 can be opened, thus facilitating the disassembly and recycling of the energy storage battery body 4. Furthermore, a movable buckle plate 21 is also movably engaged at the bottom of the front of the protective box body 1. The movable buckle plate 21 is engaged between the bottom of the partition 2 and the bottom of the inner wall of the protective box body 1. By removing the movable buckle, the area below the partition 2 can be accessed.

[0056] The protective box body 1 is movably connected to the movable door 18, so that the protective box can be opened or closed, thereby enabling the energy storage battery body 4 to be placed or removed when the protective box is opened, and ensuring the storage environment of the energy storage battery body 4 when the protective box is closed.

[0057] The two free ends of the movable frame 5 are slidably engaged with the partition 2, allowing it to rise and fall vertically. When it is necessary to place or remove the energy storage battery body 4, the movable frame 5 can be raised first, then the energy storage battery body 4 can be placed on the partition 2, and then the movable frame 5 can be lowered so that the closed end of the movable frame 5 overlaps the top wall of the energy storage battery body 4. The movable frame 5 and the partition cooperate to fix the position of the energy storage battery body 4. After fixing the energy storage battery body 4, the movable frame 5 keeps the closed end in contact with the top of the energy storage battery body 4 under its own weight, thus limiting the vertical movement of the energy storage battery body 4. Furthermore, because there is friction between the closed end of the movable frame 5 and the top of the energy storage battery body 4, it also limits the axial movement of the energy storage battery body 4 along the receiving area. The two sides of the movable frame 5 can limit the lateral movement of the energy storage battery body 4, thus fixing and limiting the energy storage battery body 4. When it is necessary to remove the energy storage battery body 4, raising the movable frame 5 will release the lock.

[0058] The protective box optimizes the fixing and disassembly method of the energy storage battery body 4, solving the problems of difficult disassembly and recycling and low efficiency in the existing technology. At the same time, it takes into account the stability of the operation of the energy storage battery body 4 and the heat dissipation requirements, and improves the reuse efficiency of the retired energy storage battery body 4.

[0059] The structure of the protective box is described in detail below:

[0060] Among the optional solutions provided in the embodiments of the present invention, see [link to relevant documentation]. Figure 2 and Figure 3 The closed end is used to be inserted into the pressure groove 6 on the top of the energy storage battery body 4.

[0061] Specifically, the protective housing body 1 is rectangular and can hold multiple energy storage battery bodies 4. These energy storage battery bodies 4 are spaced apart along the length of the protective housing body 1. Multiple movable components are also spaced apart along the length of the protective housing body 1, forming multiple accommodating areas with the partition 2 to hold the energy storage battery bodies 4. This arrangement ensures that after opening the movable door 18, all energy storage battery bodies 4 placed within their respective accommodating areas, or any available accommodating areas, are visible, facilitating the disassembly or installation of the energy storage battery bodies 4. A pressure groove 6 on the top of each energy storage battery body 4 extends along the length of the protective housing body 1.

[0062] The top wall of the energy storage battery body 4 is recessed downwards to form a groove, and the closed end of the movable frame 5 is inserted downwards into the pressure groove 6, increasing the contact area between the movable frame 5 and the energy storage battery body 4 and enhancing the limiting effect. Furthermore, because the closed end of the movable frame 5 is embedded in the pressure groove 6, both side walls of the pressure groove 6 are in contact with the movable frame 5, which enhances the limiting effect of the movable frame 5 on the energy storage battery body 4 along the width direction of the protective box body 1. The two free ends of the movable frame 5 can limit the energy storage battery body 4 along the length direction of the protective box body 1. The closed end of the movable frame 5 is in contact with the top of the energy storage battery body 4, and its own weight can limit the energy storage battery body 4 in the vertical direction.

[0063] Among the optional solutions provided in the embodiments of the present invention, see [link to relevant documentation]. Figure 4 and Figure 5 The protective box also includes a fixing component. The fixing component is installed below the partition 2 in the vertical direction and is located between the two free ends of the movable frame 5. The fixing component is inserted into the two free ends of the movable frame 5.

[0064] Specifically, both free ends of the movable frame 5 pass through the partition 2 from above to below it and are plugged into the fixed components.

[0065] The fixing component is used to restrict the movement of the free end of the movable frame 5, and to prevent the movable frame 5 from falling out of the pressure groove 6 of the energy storage battery body 4 and thus failing to play a limiting role.

[0066] Among the optional solutions provided in the embodiments of the present invention, see [link to relevant documentation]. Figure 5 The fixing components include a mounting frame 7, a double-ended screw 9, and two plug-in blocks 12. The mounting frame 7 is located between the two free ends of the movable frame 5. The two plug-in blocks 12 are slidably engaged with the two opposite side walls of the mounting frame 7. The double-ended screw 9 is installed inside the mounting frame 7, and its two ends are threadedly connected to the two plug-in blocks 12 to drive the plug-in blocks 12 to move toward or away from the free ends of the movable frame 5.

[0067] Specifically, a mounting frame 7 is fixedly connected to the bottom surface of the partition 2, and a double-ended screw 9 is rotatably connected inside the mounting frame 7. Both ends of the double-ended screw 9 are threadedly connected to plug-in blocks 12. The plug-in blocks 12 are movably plugged into the mounting frame 7.

[0068] By rotating the double-ended screw 9, the threaded action can drive the plug-in block 12 to move, so that the end of the plug-in block 12 abuts against the movable frame 5 to limit the movable frame 5; by rotating the double-ended screw 9 in the opposite direction, the threaded action can drive the plug-in block 12 to move, so that the end of the plug-in block 12 separates from the movable frame 5 to release the limiting effect on the movable frame 5.

[0069] In the optional solution provided by the embodiments of the present invention, the protective box further includes an adjusting worm gear 8 and a handwheel 10; the fixing component further includes a worm wheel 11; the worm wheel 11 is installed in the middle of the double-ended screw 9, the adjusting worm gear 8 is geared with multiple worm wheels 11, and the handwheel 10 is installed at one end of the adjusting worm gear 8.

[0070] Specifically, a handwheel 10 is fixedly connected to one end of the adjusting worm gear 8, and a worm wheel 11 is fixedly sleeved in the middle of the double-ended screw 9, with the worm wheel 11 meshing with the adjusting worm gear 8. The length of the adjusting worm gear 8 is set along the width of the protective box body 1, and the handwheel 10 is installed at one end near the movable door 18, making it convenient for the operator to turn the handwheel 10 to adjust the fixed components. Furthermore, the movable components include multiple movable frames 5, which are spaced apart and all slide in cooperation with the partition 2; the receiving area formed by the multiple movable frames 5 and the partition 2 is connected; that is, the multiple movable frames 5 are spaced apart along the width of the protective box body 1, and the multiple movable frames 5 simultaneously fix one energy storage battery body 4, enhancing the limiting effect on the energy storage battery body 4. Preferably, there are two movable frames 5, and each movable frame 5 is equipped with an installation frame 7. An adjusting worm gear 8 is rotatably connected between the two installation frames 7, so that one adjusting worm gear 8 can control multiple fixed components at the same time, which is convenient for operation, especially for controlling the fixed components located on the side of the protective box body 1 away from the movable door 18.

[0071] By turning the handwheel 10, the operator can control the rotation of the adjusting worm 8, which in turn drives the worm wheel 11, which meshes with the adjusting worm 8, to rotate. The worm wheel 11 then drives the double-ended screw 9 to rotate, thus controlling the double-ended screw 9. Furthermore, the worm wheel 11 and the adjusting worm 8 have a self-locking mechanism, which effectively prevents the double-ended screw 9 from loosening during use, thereby ensuring the stability of the structure.

[0072] In the optional solution provided by the embodiment of the present invention, the free end of the movable frame 5 is provided with a positioning groove 13, and the plug-in block 12 is plugged into the positioning groove 13.

[0073] Specifically, the surface of the movable frame 5 is provided with a positioning groove 13, and the inner wall of the positioning groove 13 is movably inserted into the end of the plug-in block 12.

[0074] The plug-in block 12 is plugged into the positioning groove 13 to enhance the limiting effect on the movable frame 5.

[0075] In the optional solution provided by the embodiments of the present invention, the plug-in block 12 includes a plug-in body and a limiting protrusion, the limiting protrusion being located inside the mounting frame 7; one end of the plug-in body is connected to the limiting protrusion, and the other end passes through the side wall of the mounting frame 7.

[0076] Specifically, the plug block 12 is T-shaped.

[0077] The limiting protrusion protrudes from the main body of the connector to prevent the connector block 12 from detaching from the mounting frame 7.

[0078] Among the optional solutions provided in the embodiments of the present invention, see [link to relevant documentation]. Figure 1 The protective box includes a linear drive component 14, which is installed on the top of the protective box body 1. The sampling end of the linear drive component 14 extends into the protective box body 1 and is connected to the movable frame 5 for transmission, so as to drive the movable frame 5 to rise and fall in the vertical direction.

[0079] Specifically, the linear drive component 14 is configured as an electric push rod, which is fixedly installed on the top surface of the protective box body 1. The telescopic end surface of the electric push rod is movably inserted into the top surface of the protective box and is connected to the movable frame 5 via transmission.

[0080] The linear drive component 14 is used to drive the movable frame 5 to rise and fall, which makes it easier to lift the movable frame 5 and release the limiting effect of the movable frame 5 on the energy storage battery body 4, thereby facilitating the disassembly of the energy storage battery body 4 and improving the degree of automation.

[0081] In the optional solution provided by the embodiments of the present invention, the movable component includes multiple movable frames 5, which are spaced apart and all slide in cooperation with the partition 2; the accommodating area formed by the multiple movable frames 5 and the partition 2 has a collinear axis.

[0082] Specifically, multiple movable frames 5 are spaced apart along the width direction of the protective box body 1.

[0083] Multiple movable frames 5 are inserted and cooperate with the same energy storage battery body 4 to improve the limiting effect on the energy storage battery body 4.

[0084] Among the optional solutions provided in the embodiments of the present invention, see [link to relevant documentation]. Figure 7 The linear drive 14 is connected to multiple movable frames 5 via a support frame 15. The support frame 15 includes a connecting arm and two transmission arms. The two ends of the connecting arm are perpendicularly connected to the two transmission arms, and the two transmission arms are located on the same side of the connecting arm. The connecting arm is connected to the linear drive 14, and both transmission arms extend into the openings of the multiple movable frames 5.

[0085] Specifically, the telescopic end of the electric push rod is fixedly connected to a connecting arm, and the two transmission arms are located in the gap between the inner side of the movable frame 5 and the left and right sides of the energy storage battery body 4.

[0086] The electric push rod is operated to drive its telescopic end to shorten, thereby pulling the support frame 15 to move upward. The support frame 15 is set in the gap between the inner side of the movable frame 5 and the left and right sides of the energy storage battery body 4. During the upward movement of the support frame 15, it will come into contact with the top inside the movable frame 5, thereby pulling the movable frame 5 to move upward.

[0087] In the optional solution provided by the embodiments of the present invention, the two free ends of two adjacent movable frames 5 located on the same side are connected by a connecting rod.

[0088] Specifically, the connecting rod extends along the width of the protective box body 1. Preferably, the connecting rod is welded to the free end of the movable frame 5.

[0089] The connecting rod connects two adjacent movable frames 5 together, which facilitates the linear drive component 14 to control the simultaneous lifting and lowering of multiple movable frames 5.

[0090] In the optional solution provided by the embodiment of the present invention, the movable component further includes a support frame 16 and a roller 17. The support frame 16 is connected to the movable frame 5 and the roller 17 is installed on the top. The axis of the roller 17 is perpendicular to the axis of the inlet and outlet. The partition 2 is provided with a receiving groove 22 opposite to the roller 17. The roller 17 can pass through the receiving groove 22 and protrude from the upper surface of the partition 2 to abut against the energy storage battery body 4.

[0091] Specifically, the roller 17 and the support frame 16 are in rolling engagement.

[0092] See Figure 6 The telescopic end of the electric push rod is fixedly connected to a support frame 15, and the surface of the connecting rod is fixedly connected to a support frame 16. A roller 17 is rotatably connected to the surface of the support frame 16. A receiving groove 22 is provided through the surface of the partition 2, and the specifications of the receiving groove 22 are adapted to the roller 17. Specifically, the length direction of the connecting rod is set along the opening direction of the inlet and outlet. Multiple support frames 16 are fixedly connected to the surface of the connecting rod. The multiple support frames 16 are spaced apart along the length direction of the connecting rod. Each support frame 16 is provided with a roller 17, and the axis of each roller 17 is perpendicular or nearly perpendicular to the length direction of the connecting rod. The partition 2 is provided with multiple receiving grooves 22 that penetrate the partition vertically. Each roller 17 corresponds to one receiving groove 22 and can pass through the corresponding receiving groove 22 vertically.

[0093] The electric push rod is operated to drive its telescopic end to shorten, thereby pulling the support frame 15 upward. The support frame 15 is set in the gap between the inner side of the movable frame 5 and the left and right sides of the energy storage battery body 4. During the upward movement of the support frame 15, it will contact the top of the inner wall of the movable frame 5, thereby pulling the movable frame 5 upward. The movable frame 5 will drive the support frame 16 and the roller 17 to rise. The roller 17 will pass through the inside of the receiving groove 22. Finally, the roller 17 will contact the bottom of the energy storage battery body 4, thereby driving the energy storage battery body 4 to rise, so that the bottom of the energy storage battery body 4 is separated from the top surface of the partition 2 and the inner wall of the positioning seat 3, thus completely releasing the restriction on the energy storage battery body 4. After opening the movable door 18, the energy storage battery body 4 can be pulled forward to disassemble it. During the process of pulling the energy storage battery body 4, the rolling action of the roller 17 makes the energy storage battery body 4 move more smoothly, reducing the friction at the bottom of the energy storage battery body 4, making it easier to remove the energy storage battery body 4.

[0094] In the optional solution provided by the embodiments of the present invention, the protective box includes a positioning seat 3, which is installed on the upper surface of the partition 2 and forms a positioning area with the partition 2 for cooperating with the bottom of the energy storage battery body 4.

[0095] Specifically, the partition 2 is fixedly connected to the inner wall of the protective box body 1. Multiple energy storage battery bodies 4 are placed on the top surface of the partition 2. A positioning seat 3 is fixedly connected to the top surface of the partition 2, and the bottom of the energy storage battery body 4 can be inserted into the interior of the positioning seat 3. The positioning seat 3 is frame-shaped and surrounds the outer periphery of the energy storage battery body 4 to limit the horizontal movement of the energy storage battery body 4.

[0096] The positioning seat 3 further enhances the limiting effect on the energy storage battery body 4.

[0097] In the optional solution provided in the embodiments of the present invention, the side wall of the protective box body 1 is provided with heat dissipation grooves 20.

[0098] Specifically, heat dissipation slots 20 are provided through the left and right sides of the protective box body 1.

[0099] The energy storage battery body 4 is located inside the protective box body 1 and is used to provide power supply. The specific power supply circuit structure is existing technology and will not be described in detail. The heat dissipation slot 20 can facilitate the heat dissipation of the energy storage battery body 4 during operation. The movable frame 5 can be used to fix the energy storage battery body 4 inside the positioning seat 3 to ensure the stability of the energy storage battery body 4.

[0100] The advantages of the protective case are explained in detail below:

[0101] Easy to disassemble and recycle:

[0102] This invention, through the design of the movable frame 5 and the electric push rod, enables the rapid fixing and disassembly of the energy storage battery body 4. During disassembly, the telescopic end of the electric push rod pulls the support frame 15 upwards, thereby causing the movable frame 5 to rise, bringing the roller 17 into contact with the bottom of the energy storage battery body 4 and lifting it, thus releasing it from the limiting position of the positioning seat 3. At this point, after opening the movable door 18, the energy storage battery body 4 can be easily pulled forward, completing the disassembly. This design eliminates the need for tools to disassemble each bolt individually, greatly improving the efficiency of disassembly and recycling, reducing operational difficulty, and minimizing the risk of damage to the battery during the disassembly process.

[0103] Improving battery stability: The energy storage battery body 4 is fixed to the separator 2 by the positioning seat 3 and further limited by the movable frame 5, ensuring the stability of the battery during operation. The positioning seat 3 can accurately fix the bottom of the battery, while the movable frame 5 constrains the battery through its internal structure, preventing the battery from shifting or being damaged due to vibration or external force. This dual fixing method effectively ensures the stability of the battery during operation, thereby extending the battery's service life.

[0104] Optimized heat dissipation: A heat dissipation groove 20 is provided through the side of the protective casing, effectively promoting heat dissipation during battery operation. The design of the heat dissipation groove 20 not only increases the airflow area but also prevents heat accumulation inside the battery pack, thus preventing performance degradation or safety hazards due to overheating. By optimizing heat dissipation, this invention improves the reliability and safety of the battery pack and extends battery life.

[0105] The structure is stable and has good self-locking properties: In this embodiment of the invention, the meshing transmission between the adjusting worm 8 and the worm wheel 11 drives the double-ended screw 9 to rotate, thereby limiting and releasing the movable frame 5. When it is necessary to fix the movable frame 5, the adjusting worm 8 is rotated by turning the handwheel 10, which in turn drives the worm wheel 11 to rotate, so that the insertion block 12 on the double-ended screw 9 is inserted into the positioning groove 13 of the movable frame 5, completing the limiting. Conversely, turning the handwheel 10 in the opposite direction can release the limiting. The self-locking effect between the worm wheel 11 and the adjusting worm 8 can effectively prevent the double-ended screw 9 from loosening during use, ensuring the stability of the entire structure.

[0106] Improved ease of operation: The protective box is equipped with a movable door 18 and a latch lock 19, facilitating quick battery replacement and maintenance. When disassembling the energy storage battery body 4, the electric push rod drives the support frame 15 to rise, which in turn raises the movable frame 5 and the roller 17. After the roller 17 contacts the bottom of the energy storage battery body 4, it reduces the friction between the bottom of the battery and the separator 2. After opening the movable door 18, the energy storage battery body 4 can be easily pulled out. The entire process is simple and greatly improves the convenience of disassembly and maintenance.

[0107] High adaptability: Through the flexible design of the positioning base 3 and the movable frame 5, this invention can adapt to various specifications of energy storage battery bodies 4. The positioning base 3 can be adjusted according to the size of the battery, and the structural design of the movable frame 5 also has a certain degree of versatility, flexibly adapting to batteries of different sizes. This design makes this invention highly versatile and adaptable, reducing usage costs and improving equipment utilization.

[0108] High safety: The protective enclosure effectively protects the energy storage battery body 4 from external environmental influences, such as dust and water. The heat dissipation slots 20 not only optimize heat dissipation performance but also facilitate ventilation inside the battery pack, further improving its safety. Furthermore, the movable latch 21 at the bottom of the protective enclosure can be easily removed, facilitating inspection and maintenance of the area below the partition 2, ensuring the cleanliness and safety of the battery pack's interior.

[0109] Example 2

[0110] The reusable energy storage battery pack provided in this embodiment of the invention includes the protective box described in Embodiment 1, and therefore also has the beneficial effects described in Embodiment 1, which will not be repeated here.

[0111] In the optional solution provided by the embodiments of the present invention, the reusable energy storage battery pack includes an energy storage battery body 4, which is installed inside the protective box body 1 of the protective box and located within the containment area.

[0112] The energy storage battery body 4 is initially fixed by snapping its bottom into the positioning seat 3. Simultaneously, the movable frame 5 is movably connected to the insertion block 12 on the double-ended screw 9 via the positioning groove 13 on its surface, thereby further limiting and fixing the energy storage battery body 4. This ensures the stability of the battery during operation and facilitates quick disassembly and installation. The support frame 15 is driven upwards by the telescopic end of the electric push rod, which in turn raises the movable frame 5. The support frame 16 on the movable frame 5 is connected to the roller 17, which rolls within the receiving groove 22 and eventually contacts the bottom of the energy storage battery body 4, lifting the battery from the positioning seat 3. The rolling action of the roller 17 significantly reduces the friction at the bottom of the battery, making the disassembly process smoother and less strenuous. The double-ended screw 9 has insertion blocks 12 threadedly connected to both ends. By rotating the double-ended screw 9, the insertion blocks 12 can move along the mounting frame 7 under the action of the threads. When the plug-in block 12 is inserted into the positioning groove 13 on the surface of the movable frame 5, the movable frame 5 is fixed in place. When disassembly is required, the double-ended screw 9 is rotated in the reverse direction, and the plug-in block 12 disengages from the positioning groove 13, thus releasing the limiting effect on the movable frame 5. The adjusting worm 8 meshes with the worm wheel 11 in the middle of the double-ended screw 9. The rotation of the adjusting worm 8 can be controlled by rotating the handwheel 10, thereby driving the worm wheel 11 and the double-ended screw 9 to rotate. The worm wheel 11 and worm structure not only achieve precise control of the double-ended screw 9, but also utilize its self-locking characteristic to prevent the screw from loosening during operation, further ensuring the stability of the battery pack.

[0114] 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.
