Description

Technical Field

[0001] This utility model relates to the field of basic electrical components technology, and in particular to a flexible lithium battery energy storage device. Background Technology

[0002] In the wave of continuous innovation in new energy technologies, lithium-ion battery energy storage devices, with their high energy conversion efficiency and stable power supply performance, have become indispensable power guarantee equipment in scenarios such as homes, industrial production, outdoor operations, and emergency rescue. As the application scope continues to expand, the flexibility and convenience of these devices during installation are receiving increasing attention. As a core component affecting the efficiency of device handling and transportation, the rationality of the hoisting structure's design directly relates to the actual user experience of the device.

[0003] Among the current lithium-ion battery energy storage devices on the market, some use a fixed lifting lug design. This type of lifting lug is rigidly connected to the device's shell by welding. While this structure can ensure a certain connection strength during lifting, the protruding lifting lugs significantly increase the overall size of the device when lifting is not required. In confined spaces such as home storage rooms or small warehouses, these devices often cannot be tightly stacked due to the presence of the lifting lugs, resulting in wasted space. During transportation, the protruding lifting lugs are prone to collisions and friction with the vehicle's cabin or other cargo. This can not only cause deformation of the lifting lugs but also scratch the protective coating on the shell surface, reducing the device's corrosion resistance, shortening its service life, and ultimately reducing the device's practicality and flexibility. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a flexible lithium battery energy storage device that can solve the problem of fixed lifting lug design. This type of lifting lug is rigidly connected to the shell of the device by welding. Although this structure can ensure a certain connection strength during the lifting process, when the lifting operation is not required, the protruding lifting lug will significantly increase the overall volume of the device. In places with relatively small spaces such as home storage rooms and small warehouses, such devices often cannot be tightly stacked due to the presence of lifting lug, resulting in wasted space. During the transportation of the device, the protruding lifting lug is easy to collide and rub against the cabin of the transport vehicle or other cargo. This may not only cause deformation of the lifting lug, but also scratch the protective coating on the surface of the shell, reducing the corrosion resistance of the device, shortening its service life, and thus reducing the practicality and flexibility of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexibly arable lithium battery energy storage device, comprising a battery compartment body, an upper cover plate, a lithium battery pack, and two side cover plates, wherein limiting components are provided on both sides of the upper end of the battery compartment body.

[0006] The limiting component includes a lifting lug, a mounting base, and a protrusion. The protrusion is fixedly installed on the outer wall of one side of the upper end of the battery compartment body. The lifting lug is rotatably connected to the groove in the outer wall of the mounting base. The outer wall of the protrusion is provided with a mounting base sliding groove. The inner walls on both sides of the mounting base sliding groove are provided with first limiting block grooves. Limiting blocks are slidably connected inside the two first limiting block grooves.

[0007] The mounting base has second limiting block grooves on both outer walls near the protrusion. The interior of each of the two first limiting block grooves is provided with a rotating threaded rod. Rotating threaded rod sleeves are rotatably connected to both sides of the protrusion. Both limiting components are located on both sides of the upper end of the battery compartment body.

[0008] Preferably, one end of the outer wall of the mounting base is slidably connected to the inside of the mounting base groove;

[0009] Among them, the ends of the two limiting blocks near the second limiting block grooves both slide into the interior of the mounting base groove and are respectively slidably connected to the interior of the corresponding second limiting block grooves.

[0010] Preferably, the outer walls of the four T-shaped blocks at the end of the mounting base near the protrusion are slidably connected to the inner walls of the four T-shaped blocks in the mounting base slide groove, and the ends of the two rotating threaded sleeves near the limiting block both extend into the inner groove of the first limiting block.

[0011] Preferably, the ends of the two rotating threaded rods near the limiting block are respectively fixedly connected to the outer wall of the corresponding limiting block;

[0012] The ends of the two rotating threaded rods furthest from the limiting block are respectively connected to the internal threads of the corresponding rotating threaded rod sleeves.

[0013] Preferably, the lithium battery pack is installed inside the main body of the battery compartment, and the outer wall of the upper cover is slidably connected to the inner walls on both sides of the upper end of the main body of the battery compartment.

[0014] The outer walls of the two side cover plates are slidably connected to the corresponding grooves on both sides of the battery compartment body. T-shaped block grooves are opened on both sides of the outer wall of the upper cover plate. The outer walls of the two T-shaped blocks at the upper end of the two side cover plates are slidably connected to the interior of the corresponding T-shaped block grooves.

[0015] Preferably, the outer walls of the protrusions at the lower ends of the two side cover plates are slidably connected to the grooves on the outer walls of the lower ends of the battery compartment body, and the lower surface of the upper cover plate is in contact with the upper end of the lithium battery pack.

[0016] Among them, the outer wall of the protrusion at the lower end of the two side cover plates is threaded with two fixing bolts, and the end of each of the four fixing bolts near the main body of the battery compartment extends into the groove at the lower end of the main body of the battery compartment and is threadedly connected to the groove inside the groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This flexibly deployable lithium-ion energy storage device allows the limiting block to disengage from the second limiting block slot of the mounting base when no hoisting operation is required, by rotating the threaded sleeve in the limiting component. This releases the limiting effect on the mounting base, allowing the mounting base and hoisting lugs to be adjusted to a suitable position or disassembled. This design avoids the problem of fixed hoisting lugs protruding from the device surface, which would increase the overall volume. In confined spaces such as home storage rooms and small warehouses, the device can be tightly stacked, eliminating wasted space due to the presence of hoisting lugs and significantly improving space utilization. Furthermore, when placing the device in different scenarios, the state of the hoisting lug assembly can be flexibly adjusted according to the actual space conditions, making the device more adaptable to various placement environments and enhancing the flexibility of device placement.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a flexible lithium battery energy storage device, including a battery compartment body 1, an upper cover plate 4, a lithium battery pack 15 and two side cover plates 5;

[0030] Limiting components are provided on both sides of the upper end of the main body 1 of the battery compartment;

[0031] The limiting assembly includes a lifting lug 2, a mounting base 3, and a protrusion 7. The protrusion 7 is fixedly installed on the outer wall of one side of the upper end of the battery compartment body 1. The lifting lug 2 is rotatably connected to the groove in the outer wall of the mounting base 3. The outer wall of the protrusion 7 has a mounting base sliding groove 12. One end of the outer wall of the mounting base 3 is slidably connected to the interior of the mounting base sliding groove 12. The inner walls on both sides of the mounting base sliding groove 12 have first limiting block grooves 13. Limiting blocks 11 are slidably connected inside the two first limiting block grooves 13. The outer walls on both sides of the mounting base 3 near the protrusion 7 have second limiting block grooves 14. The ends of the two limiting blocks 11 near the second limiting block grooves 14 slide into the interior of the mounting base sliding groove 12 and are respectively connected to the corresponding second limiting block grooves. The internal sliding connection of 14 is as follows: the outer wall of the four T-shaped blocks at the end of the mounting base 3 near the protrusion 7 is slidably connected to the inner wall of the four T-shaped block grooves of the mounting base slide groove 12. The interior of the two first limiting block grooves 13 is provided with rotating threaded rods 10. Rotating threaded rod sleeves 9 are rotatably connected to both sides of the protrusion 7. The ends of the two rotating threaded rod sleeves 9 near the limiting block 11 are rotatably extended into the interior of the first limiting block groove 13. The ends of the two rotating threaded rods 10 near the limiting block 11 are respectively fixedly connected to the outer wall of the corresponding limiting block 11. The ends of the two rotating threaded rods 10 away from the limiting block 11 are respectively threadedly connected to the interior of the corresponding rotating threaded rod sleeves 9. The two limiting components are both provided on both sides of the upper end of the battery compartment body 1.

[0032] The lithium battery pack 15 is installed inside the battery compartment body 1. The outer wall of the upper cover plate 4 is slidably connected to the inner walls of the upper two sides of the battery compartment body 1. The outer walls of the two side cover plates 5 are slidably connected to the grooves on both sides of the battery compartment body 1. T-shaped block grooves 8 are provided on both sides of the upper cover plate 4. The outer walls of the two T-shaped blocks at the upper end of the two side cover plates 5 are slidably connected to the corresponding T-shaped block grooves 8. The outer walls of the protrusions at the lower end of the two side cover plates 5 are slidably connected to the grooves on both sides of the lower end of the battery compartment body 1. The lower surface of the upper cover plate 4 is in contact with the upper end of the lithium battery pack 15. Two fixing bolts 6 are threadedly connected to the outer walls of the protrusions at the lower end of the two side cover plates 5. The ends of the four fixing bolts 6 near the battery compartment body 1 are threaded to the grooves at the lower end of the battery compartment body 1 and are threadedly connected to the grooves in the grooves.

[0033] Furthermore, when using this device, firstly, when the lithium battery energy storage device needs to be hoisted, push the mounting base 3 so that it slides within the mounting base groove 12 of the protrusion 7. Simultaneously, the T-shaped block at one end of the mounting base 3 slides within the T-shaped block groove on the inner wall of the mounting base groove 12, ensuring the stability of the mounting base 3's sliding. After adjusting the mounting base 3 to a suitable position, rotate the threaded rod sleeve 9, causing the threaded rod 10 to move the limiting block 11 closer to the mounting base 3 until the limiting block 11 slides into the second limiting block groove 14 of the mounting base 3, thus fixing the mounting base 3. At this point, due to the hoisting... Ear 2 is rotatably connected to the groove on the outer wall of mounting base 3. This allows for the connection of lifting equipment components such as hooks to ear 2. The rotational characteristics of ear 2 are used to adjust to a suitable lifting angle, enabling the lifting of the entire device. After lifting, when disassembling the ear assembly, the threaded rod sleeve 9 is rotated in the opposite direction, causing the threaded rod 10 to move the limiting block 11 away from mounting base 3 until the limiting block 11 disengages from the second limiting block groove 14 of mounting base 3, thus disassembling mounting base 3. Then, when installing the top cover 4 and side cover 5, the lithium battery pack 15 is first installed... Install the top cover 4 into the battery compartment body 1, then slide the top cover 4 along the inner walls of the upper sides of the battery compartment body 1 so that the lower surface of the top cover 4 contacts the upper end of the lithium battery pack 15. Next, slide the two side cover plates 5 along the grooves on both sides of the battery compartment body 1 so that the T-shaped blocks at the upper end of the side cover plates 5 slide into the T-shaped block grooves 8 on both sides of the top cover 4. At the same time, the protrusions at the lower end of the side cover plates 5 slide into the grooves opened on the outer walls of the lower sides of the battery compartment body 1. After the side cover plates 5 are installed in place, tighten the fixing bolts 6 on the outer wall of the protrusions at the lower end of the side cover plates 5 so that the thread of the fixing bolts 6 near the battery compartment body 1 extends to the battery. The side cover plate 5 is firmly fixed in the threaded groove inside the lower recess of the main body 1 of the battery compartment. The upper cover plate 4 is fixed by the connection between the side cover plate 5 and the upper cover plate 4. The upper cover plate 4 and the side cover plate 5 together protect the lithium battery pack 15 inside the main body 1 of the battery compartment and prevent external factors from damaging it. When it is necessary to maintain or replace the lithium battery pack 15, loosen the fixing bolts 6 and slide the side cover plate 5 out along the grooves on both sides of the main body 1 of the battery compartment. At the same time, the upper cover plate 4 will also be pulled out with the sliding of the side cover plate 5, so that the lithium battery pack 15 inside can be operated.

[0034] When hoisting is not required, the limiting block 11 can be disengaged from the second limiting block slot 14 of the mounting base 3 by rotating the threaded sleeve 9, thus releasing the limitation on the mounting base 3. This allows the mounting base 3 and the hoisting lug 2 to be adjusted to a suitable position or disassembled. This design avoids the problem of the fixed hoisting lug protruding from the surface of the device, which would increase the overall volume. In small spaces such as home storage rooms and small warehouses, the device can be tightly stacked, eliminating the waste of space due to the presence of the hoisting lug and significantly improving space utilization. At the same time, when placing the device in different scenarios, the state of the hoisting lug assembly can be flexibly adjusted according to the actual space conditions, making the device more adaptable to various placement environments and enhancing the flexibility of device placement.

[0035] Structural Description: Battery compartment body 1: The battery compartment body 1 is the basic frame and load-bearing component of the entire lithium battery energy storage device, providing installation and housing space for all other components. Its interior is used to install the lithium battery pack 15. It is the core load-bearing structure of the device, supporting the weight of the entire device and the stability of the internal components. The upper two sides are provided with protrusions 7, which provide a basis for the installation of the limiting components. Grooves are also provided on both sides for connecting with the side cover plate 5.

At the same time, threaded grooves corresponding to the fixing bolts 6 are provided inside to fix the side cover plate 5.

[0036] Lifting lug 2: Rotatably connected to the groove opened on the outer wall of the mounting base 3. This rotational characteristic allows it to be flexibly adjusted according to the lifting angle during the lifting process, making it convenient to connect with components such as hooks of lifting equipment and providing a point of force for the lifting of the device;

[0037] Mounting base 3: One end of its outer wall is slidably connected to the inside of the mounting base slide groove 12 of the protrusion 7, and can slide within the mounting base slide groove 12 to adjust its position.

[0042] Lithium battery pack 15: Installed inside the main body 1 of the battery compartment, it is the core component for the device to realize the energy storage function. It can store and release electrical energy to provide power support for external equipment. Its upper end is in contact with the lower surface of the upper cover plate 4, and the upper cover plate 4 provides certain limits and protection for it.

[0043] The upper cover plate 4 has an outer wall that is slidably connected to the inner walls on both sides of the upper end of the battery compartment body 1. It can be slidably installed or removed along the upper end of the battery compartment body 1. Its lower surface is in contact with the upper end of the lithium battery pack 15, which covers and protects the lithium battery pack 15 and prevents external dust, debris and other objects from entering the battery compartment body 1 and affecting the operation of the lithium battery pack 15. T-shaped block grooves 8 are provided on both outer walls for connecting with the T-shaped blocks on the upper end of the side cover plate 5 to realize the linkage between the upper cover plate 4 and the side cover plate 5.

[0044] Side cover 5: There are two of them. The outer wall of the side cover 5 is slidably connected to the grooves on both sides of the battery compartment body 1. The side cover 5 can slide along the grooves on both sides of the battery compartment body 1. There are two T-shaped blocks at the top. The outer wall of the T-shaped block is slidably connected to the groove 8 of the corresponding upper cover 4 to achieve the connection with the upper cover 4. There is a protrusion at the bottom. The outer wall of the protrusion is slidably connected to the grooves on both sides of the lower end of the battery compartment body 1. The outer wall of the protrusion is threaded with two fixing bolts 6. The fixing bolts 6 are connected to the threaded grooves in the grooves at the lower end of the battery compartment body 1 to achieve the fixation of the side cover 5.

[0045] Fixing bolt 6: Threaded connection to the outer wall of the protrusion at the lower end of the side cover plate 5. The threaded end near the battery compartment body 1 extends into the groove at the lower end of the battery compartment body 1 and is threadedly connected to the groove inside the groove. By tightening the fixing bolt 6, the side cover plate 5 can be firmly fixed to the battery compartment body 1, ensuring the stable installation of the side cover plate 5. Loosening the fixing bolt 6 can release the fixation of the side cover plate 5, making it easy to disassemble the side cover plate 5.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings.
