[0030] Example 1 An energy storage battery pack is a device used to store and release electrical energy. It consists of multiple battery cells connected in series, parallel, or a combination of these to meet specific voltage, capacity, and power requirements. With the rapid development of the electric vehicle industry, the rate of power battery retirement is accelerating. Although retired power batteries may have degraded performance, they still possess a certain level of energy storage capacity. To effectively utilize these retired batteries and encourage the recycling of power battery technologies, a "secondary utilization" strategy is currently being widely adopted. This involves selecting high-performing battery cells or modules for reuse in other applications. Currently, mainstream battery packs are bolted to the battery box or support frame. Disassembling and recycling individual battery cells or modules requires tools to remove the bolts one by one, a time-consuming and labor-intensive process that is inefficient and prone to damage.

[0031] In view of this, see Figures 1 to 8 The protective box provided in an embodiment of the present invention is used to accommodate an energy storage battery body 4, and includes 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 in the protective box body 1, and the protective box body 1 is also provided with an entrance and exit for the energy storage battery body to enter, and the movable door 18 is movably connected to the entrance and exit; 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 matched with the partition 2; in the vertical direction, the closed end of the movable frame 5 is located above the partition 2, and is enclosed with the partition 2 to form 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.

[0032] Specifically, see Figure 1 A movable door 18 is hingedly connected to the front of the protective box body 1. A hasp lock 19 is provided between the movable door 18 and the protective box body 1. By releasing the hasp lock 19, the movable door 18 can be opened, thereby facilitating the disassembly and recovery of the energy storage battery body 4. Furthermore, a movable plate 21 is movably connected to the bottom of the front of the protective box body 1. The movable plate 21 is fixed between the bottom of the partition 2 and the bottom of the inner wall of the protective box body 1. By removing the movable latch, the position below the partition 2 can be operated.

[0033] 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.

[0034] The two free ends of the movable frame 5 slide in conjunction with the partition 2, allowing it to be raised and lowered vertically. When the energy storage battery body 4 needs to be placed or removed, the movable frame 5 can be first raised, the energy storage battery body 4 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 cooperates with the partition to fix the position of the energy storage battery body 4. After the energy storage battery body 4 is fixed, the movable frame 5 maintains the closed end in contact with the top of the energy storage battery body 4 under the action of its own gravity, thereby limiting the vertical movement of the energy storage battery body 4. In addition, due to the friction between the closed end of the movable frame 5 and the top of the energy storage battery body 4, the axial movement of the energy storage battery body 4 along the storage area is limited. The two sides of the movable frame 5 can limit the left and right movement of the energy storage battery body 4, thus fixing the energy storage battery body 4. When the energy storage battery body 4 needs to be removed, the movable frame 5 can be raised to release the lock.

[0035] The protective box optimizes the fixing and disassembly methods of the energy storage battery body 4, solving the problems of difficult and inefficient disassembly and recycling in the existing technology, while taking into account the stability and heat dissipation requirements of the operation of the energy storage battery body 4, and improving the reuse efficiency of the retired energy storage battery body 4.

[0036] The following is a detailed description of the structure of the protective box: In the optional solutions provided in the embodiments of the present invention, see Figure 2 and Figure 3 The closed end is used to be inserted into the pressing groove 6 on the top of the energy storage battery body 4.

[0037] Specifically, the protective box body 1 is a rectangular parallelepiped, housing multiple energy storage battery bodies 4. These multiple energy storage battery bodies 4 are spaced apart along the length of the protective box body 1. Multiple movable assemblies are provided, spaced apart along the length of the protective box body 1, forming multiple storage areas for the energy storage battery bodies 4 together with the partitions 2. Furthermore, this arrangement allows each energy storage battery body 4 placed within a storage area, or any unoccupied storage areas, to be visible after opening the movable door 18, facilitating removal or installation of the energy storage battery bodies 4. A pressure groove 6 on the top of the energy storage battery body 4 extends along the length of the protective box body 1.

[0038] The top wall of the energy storage battery body 4 is recessed downward to form a groove, and the closed end of the movable frame 5 is inserted downward into the pressing groove 6, which increases the contact area between the movable frame 5 and the energy storage battery body 4 and enhances the limiting effect. Moreover, because the closed end of the movable frame 5 is embedded in the pressing groove 6, both side walls of the pressing groove 6 are in contact with the movable frame 5, which can enhance 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 achieve a limiting effect on 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 can achieve a limiting effect on the energy storage battery body 4 in the vertical direction by using its own gravity.

[0039] In the optional solutions provided in the embodiments of the present invention, see Figure 4 and Figure 5 The protective box also includes a fixed component, which is installed below the partition 2 in the vertical direction and is located between the two free ends of the movable frame 5; the fixed component is plugged into the two free ends of the movable frame 5.

[0040] Specifically, both free ends of the movable frame 5 pass through the partition 2 from above the partition 2 to below the partition 2 and are plugged into and matched with the fixed assembly.

[0041] The fixing assembly is used to limit the movement of the free end of the movable frame 5 to prevent the movable frame 5 from being separated from the pressing groove 6 of the energy storage battery body 4 and failing to play a limiting role.

[0042] In the optional solutions provided in the embodiments of the present invention, see Figure 5 The fixing assembly includes a mounting frame 7, a stud 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 slide in conjunction with the two opposite side walls of the mounting frame 7; the stud screw 9 is installed in the mounting frame 7, and its two ends are respectively threadedly connected to the two plug-in blocks 12 to drive the plug-in blocks 12 to move toward or away from the free end of the movable frame 5.

[0043] Specifically, the bottom surface of the partition 2 is fixedly connected to the mounting frame 7, the interior of the mounting frame 7 is rotatably connected to a double-headed screw 9, and both ends of the double-headed screw 9 are threadedly connected to a plug-in block 12. The plug-in block 12 is movably plugged into the mounting frame 7.

[0044] By rotating the double-headed screw 9, the plug-in block 12 can be driven to move under the action of the thread, 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-headed screw 9 in the opposite direction, the plug-in block 12 can be driven to move under the action of the thread, so that the end of the plug-in block 12 is separated from the movable frame 5 to release the limiting effect on the movable frame 5.

[0045] In the optional solution provided by an embodiment of the present invention, the protective box also includes an adjusting worm 8 and a handwheel 10; the fixing assembly also includes a worm gear 11; the worm gear 11 is installed in the middle of the double-headed screw 9, the adjusting worm 8 is matched with multiple worm gears 11, and the handwheel 10 is installed at one end of the adjusting worm 8.

[0046] Specifically, one end of the adjusting worm 8 is fixedly connected to a handwheel 10, and the middle part of the double-headed screw 9 is fixedly sleeved with a worm gear 11, and the worm gear 11 is engaged with the adjusting worm 8. The length direction of the adjusting worm 8 is arranged along the width direction of the protective box body 1, and the handwheel 10 is installed at one end close to the movable door 18, so that the operator can turn the handwheel 10 to adjust the fixed component. Furthermore, the movable component includes a plurality of movable frames 5, and the plurality of movable frames 5 are arranged at intervals, and all of them are slidably matched with the partition 2; the accommodating area enclosed by the plurality of movable frames 5 and the partition 2 is connected; that is, the plurality of movable frames 5 are arranged at intervals along the width direction of the protective box body 1, and the plurality of movable frames 5 simultaneously fix one energy storage battery body 4, thereby enhancing the limiting effect on the energy storage battery body 4. Preferably, two movable frames 5 are provided, and an installation frame 7 is installed in each movable frame 5; an adjusting worm 8 is rotatably connected between the two installation frames 7, so that one adjusting worm 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.

[0047] By turning the handwheel 10, the operator can control the rotation of the adjusting worm 8, which in turn drives the worm wheel 11 meshing with the adjusting worm 8 to rotate. The worm wheel 11 then drives the double-headed screw 9 to rotate, thereby achieving control of the double-headed screw 9. In addition, the worm wheel 11 and the adjusting worm 8 can achieve a self-locking effect, which can effectively prevent the double-headed screw 9 from loosening during use, thereby ensuring the stability of the structure.

[0048] In an optional solution provided by an embodiment of the present invention, a positioning groove 13 is provided at the free end of the movable frame 5 , and the plug-in block 12 is plugged into and matched with the positioning groove 13 .

[0049] Specifically, a positioning groove 13 is formed on the surface of the movable frame 5 , and the inner wall of the positioning groove 13 is movably plugged into the end of the plug-in block 12 .

[0050] The plug-in block 12 is plugged into the positioning groove 13 to enhance the limiting effect on the movable frame 5.

[0051] In the optional solution provided by the embodiment of the present invention, the plug-in block 12 includes a plug-in body and a limiting protrusion, and the limiting protrusion is located in the installation 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 installation frame 7.

[0052] Specifically, the plug-in block 12 is T-shaped.

[0053] The limiting protrusion protrudes from the plug-in body to prevent the plug-in block 12 from being separated from the installation frame 7 .

[0054] In the optional solutions provided in the embodiments of the present invention, see Figure 1 The protective box includes a linear drive member 14, which is installed on the top of the protective box body 1, and the sampling end of the linear drive member 14 extends into the protective box body 1 and is transmission-connected to the movable frame 5 to drive the movable frame 5 to rise and fall in the vertical direction.

[0055] Specifically, the linear drive member 14 is configured as an electric push rod, which is fixedly mounted on the top surface of the protective box body 1 , and the telescopic end surface of the electric push rod is movably plugged into the top surface of the protective box and is transmission-connected to the movable frame 5 .

[0056] The linear drive member 14 is used to drive the movable frame 5 to rise and fall, so as to facilitate lifting the movable frame 5 to 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.

[0057] In the optional solution provided by the embodiment of the present invention, the movable assembly includes multiple movable frames 5, which are arranged at intervals and all slide in conjunction with the partition 2; the axes of the accommodation area enclosed by the multiple movable frames 5 and the partition 2 are collinear.

[0058] Specifically, a plurality of movable frames 5 are arranged at intervals along the width direction of the protection box body 1 .

[0059] A plurality of movable frames 5 are plugged into and matched with the same energy storage battery body 4 , thereby improving the limiting effect on the energy storage battery body 4 .

[0060] In the optional solutions provided in the embodiments of the present invention, see Figure 7 The linear drive member 14 is connected to the multiple movable frames 5 through the support frame 15; the support frame 15 includes a connecting arm and two transmission arms, the two ends of the connecting arm are respectively connected vertically 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 member 14, and the two transmission arms both extend into the openings of the multiple movable frames 5.

[0061] 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.

[0062] 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 of the inner part of the movable frame 5, thereby pulling the movable frame 5 to move upward.

[0063] In an optional solution provided by an embodiment of the present invention, in two adjacent movable frames 5 , the two free ends located on the same side are connected by a connecting rod.

[0064] Specifically, the connecting rod extends along the width direction of the protective box body 1. Preferably, the connecting rod is welded to the free end of the movable frame 5.

[0065] The connecting rod connects two adjacent movable frames 5 together, thereby facilitating the linear drive member 14 to control the simultaneous lifting of multiple movable frames 5 .

[0066] In the optional solution provided in the embodiment of the present invention, the movable component also includes a supporting frame 16 and a roller 17. The supporting frame 16 is connected to the movable frame 5, and a roller 17 is installed on the top, and 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, and 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.

[0067] Specifically, the roller 17 and the support bracket 16 are in rolling cooperation.

[0068] See also Figure 6 The telescopic end of the electric push rod is fixedly connected to a support frame 15, and a support bracket 16 is fixedly connected to the surface of the connecting rod. A roller 17 is rotatably connected to the surface of the support bracket 16. A receiving groove 22 is formed on the surface of the partition 2, and the specifications of the receiving groove 22 are compatible with the roller 17. Specifically, the length direction of the connecting rod is arranged along the opening direction of the inlet and outlet. Multiple support brackets 16 are fixedly connected to the surface of the connecting rod. Multiple support brackets 16 are arranged at intervals along the length of the connecting rod. Each support bracket 16 is provided with a roller 17, and the axis of each roller 17 is perpendicular or nearly perpendicular to the length of the connecting rod. The partition 2 is provided with multiple receiving grooves 22 that penetrate the partition in the vertical direction. Each roller 17 corresponds to a receiving groove 22 and can pass through the corresponding receiving groove 22 in the vertical direction.

[0069] When the lifting mechanism 15 is lifted up, the lifting mechanism 15 is lifted up, and the lifting mechanism 15 is lifted up, so that the lifting mechanism 15 can be lifted up and the lifting mechanism 15 is lifted up.

[0070] In an optional solution provided by an embodiment 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.

[0071] 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 positioning seat 3. The positioning seat 3 is frame-shaped and surrounds the outer periphery of the energy storage battery body 4, limiting the horizontal movement of the energy storage battery body 4.

[0072] The positioning seat 3 further improves the limiting effect on the energy storage battery body 4.

[0073] In an optional solution provided by an embodiment of the present invention, a heat dissipation groove 20 is provided on the side wall of the protective box body 1 .

[0074] Specifically, heat dissipation slots 20 are formed through the left and right sides of the protective box body 1 .

[0075] 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 repeated here. The heat dissipation groove 20 can facilitate heat dissipation during the operation of the energy storage battery body 4. 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.

[0076] The following is a detailed description of the advantages of the protective box: Easy to disassemble and recycle: The embodiment of the present invention achieves rapid securing and removal of the energy storage battery body 4 through the design of the movable frame 5 and the electric push rod. During removal, the telescopic end of the electric push rod pulls the support frame 15 upward, thereby driving the movable frame 5 upward, allowing the roller 17 to contact the bottom of the energy storage battery body 4 and lift it, freeing it from the position limit of the positioning seat 3. At this time, after opening the movable door 18, the energy storage battery body 4 can be easily pulled forward to complete the removal. This design eliminates the need for tools to remove bolts one by one, greatly improving the efficiency of disassembly and recovery, reducing the difficulty of operation, and minimizing the risk of damage to the battery during the disassembly process.

[0077] Improved battery stability: The energy storage battery body 4 is secured to the partition 2 via a positioning base 3 and further restrained by a movable frame 5, ensuring battery stability during operation. The positioning base 3 precisely secures the battery's bottom, while the movable frame 5, through its internal structure, constrains the battery, preventing displacement or damage due to vibration or external forces. This dual-fixation method effectively ensures battery stability during operation, thereby extending its service life.

[0078] Optimized heat dissipation: Heat dissipation slots 20 are provided through the sides of the protective box, effectively dissipating heat during battery operation. These slots not only increase the area for air circulation but also prevent heat accumulation within the battery pack, thereby preventing overheating that could lead to performance degradation or safety hazards. By optimizing heat dissipation, this invention enhances the reliability and safety of the battery pack and extends the battery's service life.

[0079] The structure is stable and has good self-locking properties: The embodiment of the present invention adopts the meshing transmission of the adjusting worm 8 and the worm wheel 11 to drive the double-headed screw 9 to rotate, thereby realizing the limiting and releasing of the movable frame 5. When the movable frame 5 needs to be fixed, the adjusting worm 8 is rotated by turning the handwheel 10, which in turn drives the worm wheel 11 to rotate, so that the plug-in block 12 on the double-headed screw 9 is inserted into the positioning groove 13 of the movable frame 5 to complete the limiting. Conversely, the limit can be released by rotating the handwheel 10 in the opposite direction. The self-locking effect between the worm wheel 11 and the adjusting worm 8 can effectively prevent the double-headed screw 9 from loosening during use, thereby ensuring the stability of the entire structure.

[0080] Improved Operational Convenience: The protective box features a movable door 18 and a hasp lock 19, facilitating quick battery replacement and maintenance. To remove the energy storage battery body 4, an electric push rod drives the support frame 15 upward, which in turn raises the movable frame 5 and roller 17. Contact between the roller 17 and the bottom of the battery body 4 reduces friction between the battery bottom and the separator 2. Opening the movable door 18 allows the battery body 4 to be easily pulled out, simplifying the entire process and significantly improving ease of removal and maintenance.

[0081] Strong adaptability: Through the flexible design of the positioning base 3 and the movable frame 5, the embodiment of the present invention can accommodate a variety 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, which can flexibly adapt to batteries of different sizes. This design makes the present invention highly versatile and adaptable, reducing operating costs and improving equipment utilization.

[0082] High Safety: The protective box design 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 but also facilitate ventilation within the battery pack, further enhancing battery pack safety. Furthermore, the removable gusset plate 21 at the bottom of the protective box allows for easy inspection and maintenance beneath the partition 2, ensuring cleanliness and safety within the battery pack.

[0083] Example 2 The reusable energy storage battery pack provided in the embodiment of the present invention includes the protective box described in the first embodiment, and therefore also has the beneficial effects described in the first embodiment, which will not be described in detail here.

[0084] In the optional solution provided by the embodiment of the present invention, the reusable energy storage battery pack includes an energy storage battery body 4, which is installed in the protective box body 1 of the protective box and is located in the accommodating area.

[0085] The energy storage battery body 4 is initially fixed by being snapped into the positioning seat 3 at its bottom. At the same time, the movable frame 5 is movably plugged into the plug-in block 12 on the double-headed screw 9 through the positioning groove 13 on its surface, thereby further limiting and fixing the energy storage battery body 4; ensuring the stability of the battery during operation and facilitating quick disassembly and installation. The support frame 15 is driven upward by the telescopic end of the electric push rod, thereby driving the movable frame 5 to rise. The supporting frame 16 on the movable frame 5 is connected to the roller 17. The roller 17 rolls in 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 more labor-saving. The plug-in block 12 is threadedly connected to both ends of the double-headed screw 9. By rotating the double-headed screw 9, the plug-in block 12 can move along the mounting frame 7 under the action of the thread. When the plug-in block 12 is inserted into the positioning slot 13 on the surface of the movable frame 5, the movable frame 5 is fixed in place. When disassembly is required, the stud screw 9 is rotated in the opposite direction, and the plug-in block 12 disengages the positioning slot 13, thereby releasing the restraining effect on the movable frame 5. The adjusting worm 8 engages with the worm gear 11 in the middle of the stud screw 9. By turning the handwheel 10, the rotation of the adjusting worm 8 can be controlled, thereby driving the rotation of the worm gear 11 and the stud screw 9. The worm gear structure of the worm gear 11 not only enables precise control of the stud screw 9, but also utilizes its self-locking properties to prevent the screw from loosening during operation, further ensuring the stability of the battery pack.
