DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1 and Figure 2 As shown, the energy storage device includes a shell, which may be a rectangular body with hollowed-out sides. The heat dissipation may be improved by providing a hollowed-out structure.

[0025] The housing includes a box body 1 and a cover plate 2, and the cover plate 2 can be fixed to the top opening of the box body 1 by screws. The cover plate 2 is a rectangular cover.

[0026] In the transverse direction, four groups of battery packs 3 for supplying power are arranged equidistantly inside the housing, and in the longitudinal direction, two groups of battery packs 3 for supplying power are arranged equidistantly.

[0027] In the horizontal direction, a mounting assembly 4 is provided inside the housing corresponding to one side of the battery pack 3 to assist in its installation, and a fixing assembly 5 is provided inside the housing corresponding to the other side of the battery pack 3 to assist in its stable fixation. An auxiliary assembly 6 is provided on the side of the cover plate 2 to assist in stable installation.

[0028] The set battery pack 3 can perform normal power supply operation, and the set battery pack 3 can be convenient for subsequent installation and disassembly. Compared with the prior art, the battery pack 3 in the energy storage device in this embodiment can be disassembled through the adhesive connection, that is, when a battery pack 3 or battery block 32 fails, it can be replaced.

[0029] like Figures 2 to 4 As shown, the battery pack 3 includes a base frame 31 fixedly mounted on the bottom side of the shell. The base frame 31 is a U-shaped frame, and the edges around it can limit the battery blocks 32. In the longitudinal direction, battery blocks 32 are equidistantly arranged inside the base frame 31. The battery blocks 32 are rectangular blocks. In the longitudinal direction, mounting grooves 33 that penetrate the circumferential edges of the base frame 31 are equidistantly opened at positions between the corresponding battery blocks 32 on the inner side of the base frame 31. The mounting grooves 33 are rectangular grooves. A heat sink 34 is movably mounted inside the mounting grooves 33, and one heat sink 34 is arranged between two adjacent battery blocks 32. The heat sink 34 is a cross-shaped rectangular plate made of aluminum, wherein the thicker part of the heat sink 34 is located in the middle of the battery block 32, which plays a role in limiting and dissipating heat, while the narrower part is located at the edge of the battery block 32, which is used to avoid the installation component 4 and the fixing component 5. Specifically, the base frame 31 can constrain the battery block 32 , and the heat sink 34 is installed inside the installation groove 33 , and can be conveniently and quickly installed between the battery blocks 32 , thereby isolating, stabilizing and dissipating heat for the battery blocks 32 .

[0030] It should be noted that in order to improve heat dissipation, support columns protruding toward the battery block 32 may be provided on the side wall of the heat sink 34, and in order to increase the pressure and prevent the support columns from poking the battery block 32, the support columns are arranged in an array. At the same time, gaps are left between the support columns arranged in the array. When the energy storage device is placed in the heat dissipation channel, that is, when air flows through the inside of the box body 1, air can flow between the support columns to quickly take away the heat. At the same time, the use of support columns instead of fins is to avoid dust accumulation between adjacent support columns, thereby blocking the gaps between adjacent support columns. Each support column is surrounded by gaps, and under the action of airflow, dust and impurities can be better discharged.

[0031] The provided installation component 4 can assist in installing the battery pack 3 , thereby ensuring convenience during installation of the battery pack 3 .

[0032] like Figure 2 , Figure 3 and Figure 5As shown, the mounting assembly 4 includes a first mounting plate 41 fixedly mounted on the bottom side of the housing, the first mounting plate 41 extends longitudinally, and the first mounting plate 41 is attached to the side of the base frame 31. The first mounting plate 41 is a rectangular plate, and a mounting cavity 42 is equidistantly provided on the side of the first mounting plate 41 close to the base frame 31 and corresponding to the position of the battery block 32. The mounting cavity 42 is a "C"-shaped cavity, and the two ends of the "C"-shaped cavity are located on the side wall of the first mounting plate 41 facing the battery block 32. A first clamping piece 431 and a second clamping piece 432 are movably mounted in a mirror image inside the mounting cavity 42, and the first clamping piece 431 and the second clamping piece 432 are attached to the two side positions of the battery block 32 that are opposite to each other in the longitudinal direction, and the first clamping piece 431 and the second clamping piece 432 are both "L"-shaped.

[0033] The top surfaces of the first clamping piece 431 and the second clamping piece 432 exposed outside the installation cavity 42 are both inclined surfaces, and the distance between the inclined surfaces on the first clamping piece 431 and the second clamping piece 432 gradually decreases from top to bottom. When the battery block 32 is placed downward, the first clamping piece 431 and the second clamping piece 432 can be automatically squeezed apart without the need for workers to manually pry apart the first clamping piece 431 and the second clamping piece 432.

[0034] A tension spring 44 is symmetrically fixedly connected between the first clamping piece 431 and the second clamping piece 432 in the same installation cavity 42 .

[0035] Specifically, the elastic tension of the tension spring 44 is set so that the first clamping piece 431 and the second clamping piece 432 are elastically clamped on the side of the battery block 32 for reset clamping. When the battery block 32 is installed, the single group of battery blocks 32 are installed into the bottom frame 31, and the battery block 32 squeezes the first clamping piece 431 and the second clamping piece 432 to make the two slide in opposite directions inside the installation cavity 42. After the battery block 32 is in place, the single group of battery blocks 32 is clamped and stabilized, and all the battery blocks 32 are installed and stabilized in turn. Then, the heat sink 34 is inserted into the battery blocks 32 in sequence and clamped in the installation slot 33. This ensures that the battery block 32 will not shift when it is not fixed, facilitates the installation of subsequent components, and improves the convenience of installation.

[0036] The fixing assembly 5 can stabilize the installed battery pack 3; like Figure 2 , Figure 3 and Figure 6As shown, the fixing assembly 5 includes a second mounting plate 51 fixedly mounted on the bottom side of the shell, and the second mounting plate 51 is attached to the other side of the bottom frame 31.

The locking clamping assembly includes a third clamping piece 5711 and a fourth clamping piece 5712. The third clamping piece 5711 and the fourth clamping piece 5712 are convex blocks made of hard rubber with circular spline grooves on the side. An adjusting block 571 is fixedly installed on the inner side of the third clamping piece 5711 and the fourth clamping piece 5712. The adjusting block 571 is threadedly sleeved to the corresponding positions of the first adjusting groove 531 and the second adjusting groove 532. The adjusting block 571 is an annular nut block with an external spline shape. A first supporting tube 572 is fixedly connected between the side of the third clamping piece 5711 and the inner wall of the inner cavity 52, and between the side of the fourth clamping piece 5712 and the inner wall of the inner cavity 52. ​​The first supporting tube 572 is a cylinder made of spring steel with a continuous "W"-shaped cross-section, which can undergo elastic deformation, so that the threads of the annular nut block are respectively fitted with the threads of the first adjusting groove 531 and the second adjusting groove 532. Specifically, the driving rod 56 is driven to rotate by a tool, and the second gear 55 rotates accordingly and engages with the first gear 54 to drive the adjusting rod 53 to rotate. The corresponding first adjusting groove 531 and the second adjusting groove 532 are threadedly engaged with the adjusting block 571, so that the third clamping piece 5711 and the fourth clamping piece 5712 slide relative to or opposite to each other inside the inner cavity 52, and the third clamping piece 5711 and the fourth clamping piece 5712 at the two sides of the corresponding battery block 32 are clamped and fixed close to each other, thereby completing the clamping and fixation of the battery block 32.

[0037] Two groups of connecting rods 58 are arranged between the second mounting plates 51 at the side positions of the longitudinally adjacent battery packs 3, and the two groups of connecting rods 58 respectively penetrate the two adjacent second mounting plates 51 and are fixedly connected to the opposite ends of the two adjacent adjustment rods 53. The connecting rods 58 are circular rods, and linkage cylinders 59 are movably sleeved on the sides of the two groups of connecting rods 58.

The locking blocks 591 are cylindrical threaded blocks. After tightening the locking blocks 591, the locking blocks 591 are crimped with the connecting rods 58 to form a fixed connection structure. Specifically, by squeezing the locking blocks 591 threads at the side positions of the connecting rods 58, the corresponding two groups of connecting rods 58 can be rotated in a linked manner, and the longitudinal corresponding position adjustment rods 53 can be rotated synchronously, thereby improving the installation and disassembly efficiency. When the battery pack 3 is installed and disassembled individually, the threads of the corresponding position locking blocks 591 can be loosened to avoid interference.

The second support cylinder 672 is a spring steel cylinder with a continuous "W"-shaped cross-section and has elastic deformation. When the pressure applied to the extrusion rod 671 is removed, the second support cylinder 672 drives it to move upward.

[0040] The lower side of the cover plate 2 is equidistantly fixed with mating rods 68, and the mating rods 68 are fitted on the top surface of the driving rod 56. The mating rods 68 are cylindrical rods made of elastic rubber. Specifically, the mating rods 68 are arranged to squeeze the top surface of the driving rod 56 to limit the driving rod 56 and prevent it from rotating. By limiting the driving rod 56, the third clamping piece 5711 and the fourth clamping piece 5712 can be guaranteed to clamp the battery block 32.

[0041] It should be noted that the top surface of the driving rod 56 has a "cross" groove, and the bottom surface of the matching rod 68 has a "cross" protrusion connected to the "cross" groove. When the cover plate 2 is installed in place, the "cross" protrusion is located in the "cross" groove, further restricting the driving rod 56.

[0042] When the cover 2 is installed on the top surface of the box body 1, press the extrusion rod 671 to make it slide downward inside the connecting groove 67. The extrusion rod 671 pushes the card plate 661 to slide downward inside the slot 66. The constraint block 662 constrains the card plate 661 so that it only moves vertically. At this time, the card plate 661 is separated from the inner wall of the active cavity 62, and the active rod 64 can slide inside the active cavity 62. The synchronous card rod 65 slides in the card slot 63 to limit the cover 2. At this time, the active rod 64 will not slide out of the active cavity 62, so that the rapid installation and positioning between the box body 1 and the cover 2 can be completed. Subsequently, the screws only need to be installed between the box body 1 and the cover 2 using tools.

[0043] Continuing the above operation in a similar manner, the movable rod 64 can continue to slide inside the movable cavity 62 until the movable rod 64 slides out of the movable cavity 62, and the battery pack can be subsequently installed and fixed for use by the extended movable rod 64, that is, when the energy storage device is fixed, a fixing part can be provided next to it, and the fixing part has a lock hole, and the extended movable rod 64 can be inserted into the lock hole, so as to connect the energy storage device with the fixing part, thereby fixing the energy storage device.

[0044] 1. Structure: The above-mentioned component arrangement facilitates the installation and removal of the battery block 32, and plays a role in the stable positioning operation when the battery block 32 is not fixed during installation, and the synchronous and rapid clamping operation when the battery block 32 is fixed. It can also choose whether to perform linkage operation and single group operation according to the battery packs 3 corresponding to different positions; in addition, it can also play a role in the stable positioning and fixing operation of the installation between the box body 1 and the cover plate 2, thereby improving the installation accuracy; 2. Materials: According to the above component material description, some structures are generally made of rubber material, which not only ensures the clamping effect, but also avoids the leakage of the internal battery block 32.

[0045] By providing the battery pack 3, the mounting assembly 4 and the fixing assembly 5, the present embodiment can enable the battery block 32 inside the battery pack to be quickly installed and removed, and the battery block 32 can be constrained during installation to prevent its position from shifting, further ensuring the convenience of installation of the battery block 32. After installation, the battery block 32 can be synchronously clamped and fixed, ensuring the stability of the battery block 32 when the battery pack is in use. Similarly, the reverse operation can also facilitate the disassembly operation of the battery block 32, facilitate subsequent maintenance, replacement and recycling, and facilitate manual operation.

[0046] 2. By setting the auxiliary component 6, the movable rod 64 performs the first sliding distance, and the movable rod 64 will not slide out of the movable cavity 62. At this time, the clamping rod 65 slides inside the clamping groove 63 to limit the cover plate 2, completing the rapid positioning and fixing of the box body 1 and the cover plate 2. The fixed cover plate 2 can constrain and limit the driving rod 56 through the matching rod 68, further ensuring the stability of clamping the battery block 32; The movable rod 64 slides for a second distance, and continues to slide inside the movable cavity 62 until the movable rod 64 slides out of the movable cavity 62. The battery pack can be subsequently installed and fixed using the extended movable rod 64, which ensures the subsequent installation of the battery pack while also ensuring the constraint and restriction between the box body 1 and the cover plate 2.

[0047] 3. By setting the installation component 4, when a single battery block 32 is installed into the bottom frame 31, the guide block is squeezed synchronously to slide inside the installation cavity 42. After loosening, the single battery block 32 is clamped and stabilized, and all battery blocks 32 are installed and stabilized in turn. Then, the heat sink 34 is inserted into the battery block 32 in sequence and snapped into the installation groove 33. This ensures that the battery block 32 will not shift when it is not fixed, facilitates the installation of subsequent components, improves the convenience of installation, and can assist in elastic clamping of the battery block 32 to ensure stability.

[0048] 4. By setting the fixing component 5, the driving rod 56 rotates to drive the second gear 55 to rotate and engage with the first gear 54 to drive the adjusting rod 53 to rotate, and the corresponding first adjusting groove 531 and the second adjusting groove 532 are threadedly engaged with the adjusting block 571, so that the third clamping piece 5711 and the fourth clamping piece 5712 slide inside, and the fixing blocks at the two sides of the corresponding battery block 32 are clamped and fixed to complete the clamping and fixing of the battery block 32. In this way, multiple groups of battery blocks 32 can be clamped and released synchronously, thereby improving the efficiency of installation and disassembly.

[0049] 5. By setting the connecting rod 58, the linkage cylinder 59 and the locking block 591, the locking block 591 is screwed on the side of the connecting rod 58, so that the corresponding two groups of connecting rods 58 can be rotated in a linked manner, and the corresponding position adjustment rods 53 can be rotated synchronously, thereby improving the installation and disassembly efficiency. When installing and disassembling a single battery pack 3, the thread of the locking block 591 at the corresponding position can be loosened to avoid interference and facilitate the subsequent removal of the battery block 32 at the corresponding position.

[0050] Example 2 The difference from Example 1 is that, in the horizontal direction, one side of the box body 1 has an air inlet hole, and the other side of the shell body has an air outlet hole. The airflow generated by the external cooling fan can generate an airflow flowing from the air inlet hole toward the air outlet hole.

[0051] like Fig.11 As shown, the inner bottom surface of the box body 1 is no longer a horizontal plane, but is inclined toward the side of the air inlet. The inner bottom surface of the box body 1 is inclined toward the side of the cover plate 2, and the inclination angle ranges from 2° to 5°, so that the top surface of the battery block 32 is set at an angle to the extension direction of the air inlet. The airflow blown in from the air inlet hits the top surface of the battery block 32, which can blow away the dust and impurities thereon. Compared with the horizontal placement of the battery block 32, the top surface of the inclined battery block 32 is subjected to a greater impact force of the airflow, and it is easier to blow away dust and impurities.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
