Description

Technical Field

[0001] The present disclosure relates to the technical field of heavy-duty energy storage, and in particular to a battery module assembly structure and a heavy-duty energy storage box. Background Art

[0002] With the widespread use of new energy, people have put forward higher requirements on the capacity of energy storage products. In order to meet market demand, manufacturers have developed heavy-duty energy storage devices, such as energy storage cabinets and energy storage containers. However, in order to simplify the structure of heavy-duty energy storage devices, some manufacturers have made further designs for the assembly and lifting and transportation requirements of each energy storage unit in heavy-duty energy storage devices.

[0003] For example, Chinese patent document CN218472068U discloses a liquid-cooled battery pack and energy storage system including: an upper box body, a lower box assembly and multiple battery modules. The multiple battery modules are deployed in a accommodating space formed by connecting the upper box body and the lower box assembly. The lower box body adopts an integrated structure combining a liquid cooling flow channel with a bottom bracket support function, thereby achieving the purpose of uniform heat dissipation for the battery modules in the box. In addition, the battery pack has a high energy density, high battery balance consistency, and is safe and reliable, thereby increasing the service life of the liquid-cooled battery pack. At the same time, it can meet the requirements of whole box load-bearing and lifting transportation, saving manufacturing and use costs.

[0004] However, the above-mentioned design of the liquid-cooled battery pack and energy storage system has the following problems:

[0005] Although the above-mentioned liquid-cooled battery pack and energy storage system can encapsulate multiple battery modules into an integrated structure through the upper box and the lower box assembly, thereby facilitating lifting and transportation, the liquid-cooled battery pack is lifted and lowered during the lifting operation and moves horizontally in the air, and multiple battery modules are grouped and bundled by multiple belts. During the lifting operation, two adjacent groups of battery modules will collide and rub against each other, which can easily cause the belts to wear and break, and eventually cause the battery modules to scatter during the lifting process.

The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0033] like Figure 1 As shown, a battery module assembly structure 10 of an embodiment includes a battery cell placement base plate 100, a first limiting guide rail 200, a second limiting guide rail 300 and a plurality of concave pressure covers 500; the first limiting guide rail 200 and the second limiting guide rail 300 are respectively fixedly arranged at the opposite side edges of the battery cell placement base plate 100, and a push clamping area 110 is formed between the first limiting guide rail 200 and the second limiting guide rail 300, and the push clamping area 110 is used to place and clamp the battery module 400; a plurality of concave pressure covers 500 are arranged side by side and covered on the push clamping area 110; each concave pressure cover 500 is respectively used to be arranged opposite to a battery cell of the battery module 400, and the first end of each concave pressure cover 500 is respectively fixedly connected to the first limiting guide rail 200, and the second end of each concave pressure cover 500 is respectively fixedly connected to the second limiting guide rail 300, so as to press and fix the battery module 400.

[0034] It can be understood that by fixing the first limiting guide rail 200 and the second limiting guide rail 300 on the opposite side edges of the battery cell placement base plate 100, a pushing clamping area 110 can be formed between the first limiting guide rail 200 and the second limiting guide rail 300. When the battery module 400 needs to be installed, the battery module 400 can be pushed into the pushing clamping area 110 from the first pushing end 1110. The battery module 400 can be moved and clamped between the first limiting guide rail 200 and the second limiting guide rail 300, so that the battery module 400 can remain in a constrained state in the vertical direction. At the same time, because each concave pressure cover 500 is arranged opposite to a battery unit of the battery module 400, by fixing the first end of each concave pressure cover 500 to the first limiting guide rail 200, and fixing the second end of each concave pressure cover 500 to the second limiting guide rail 300, each concave pressure cover 500 can be securely covered on the battery module 400 to press and fix the battery module 400.

[0035] It can be understood that, compared with the liquid-cooled battery pack and energy storage system of the prior art, the above-mentioned battery module assembly structure 10, by clamping the battery module 400 through the first limiting guide rail 200 and the second limiting guide rail 300, can not only effectively reduce the lateral shaking of the battery module 400 during hoisting and transportation, but also prevent the battery module 400 from being offset or misaligned during the assembly process. At the same time, each concave pressure cover 500 is pressed against a battery cell of the battery module 400, so that the battery module 400 can be pressed against the bottom plate, thereby clamping and fixing the battery module 400, so that adjacent battery modules 400 are not easy to collide and rub against each other, which can reduce the occurrence of scattering of each battery module 400 during the hoisting process, thereby improving the stability of the above-mentioned battery module assembly structure 10.

[0036] In one embodiment, the battery unit is composed of a plurality of cylindrical cells connected in series and in parallel. It can be understood that by connecting a plurality of cylindrical cells in series and in parallel, a battery unit with greater energy can be formed, which is more convenient to use.

[0037] Please also read Figures 1 to 3Further, the first position limiting guide rail 200 is provided with a first position limiting mounting hole 210, and the second position limiting guide rail 300 is provided with a second position limiting mounting hole 310; the first mounting end 510 is provided with a first mounting hole 5110, and the second mounting end 520 is provided with a second mounting hole 5210; the first mounting hole 5110 is correspondingly connected with the first position limiting mounting hole 210, and the first mounting hole 5110 and the first position limiting mounting hole 210 are used for passing the first bolt, and the second mounting hole 5210 is correspondingly connected with the second position limiting mounting hole 310, and the second mounting hole 5210 and the second position limiting mounting hole 310 are used for passing the second bolt. It can be understood that by passing the first bolt through the first mounting hole 5110 and the first limiting mounting hole 210, the first mounting end 510 can be tightly connected to the first limiting guide rail 200, and at the same time, the second bolt passes through the second mounting hole 5210 and the second limiting mounting hole 310, so that the second mounting end 520 can be tightly connected to the second limiting guide rail 300, so that the concave pressure cover 500 will not loosen or shift during use, and can tightly fix the battery module 400.

[0038] Combination Figure 1 and Figure 4 As shown, in this embodiment, the concave gland 500 includes a first mounting end 510 and a second mounting end 520; the first mounting end 510 is connected to the first limiting guide rail 200, and the second mounting end 520 is connected to the second limiting guide rail 300. It can be understood that by connecting the first mounting end 510 to the first limiting guide rail 200 and the second mounting end 520 to the second limiting guide rail 300, the position of the concave gland 500 is ensured to be fixed, so that the position of the battery module 400 is fixed and clamped.

[0039] Combination Figure 1As shown, in the present embodiment, the battery module assembly structure 10 also includes a first mounting pull strip 610 and a second mounting pull strip 620; the first mounting pull strip 610 is arranged on a plurality of concave pressure covers 500, the first mounting pull strip 610 is parallel to the first limiting guide rail 200, and is respectively screwed to the first mounting end 510 of each concave pressure cover 500; the second mounting pull strip 620 is arranged on a plurality of concave pressure covers 500, the second mounting pull strip 620 is parallel to the second limiting guide rail 300, and is respectively screwed to the second mounting end 520 of each concave pressure cover 500. It can be understood that the first mounting pull bar 610 and the second mounting pull bar 620 provide additional support for the battery module 400 by being arranged on multiple concave pressure covers 500. By arranging the first mounting pull bar 610 and the second mounting pull bar 620 parallel to the first limiting guide rail 200 and the second limiting guide rail 300 respectively and corresponding to the setting position of the concave pressure cover 500, the parallelism between the pull bar and the guide rail is ensured, so that the battery module 400 remains stable during the assembly process and the assembly difficulties caused by poor alignment are avoided. By making the first mounting pull bar 610 respectively screwed to the first mounting end 510 of each concave pressure cover 500, and making the second mounting pull bar 620 respectively screwed to the second mounting end 520 of each concave pressure cover 500, each concave pressure cover 500 is connected into one, thereby enhancing the structural strength of each concave pressure cover 500 and ultimately improving the fixing effect on each battery module 400.

[0040] Combination Figure 1 and Figure 4 As shown, in one embodiment, the battery module assembly structure 10 further includes a first module baffle 700 and a second module baffle 800; the first module baffle 700 is disposed at the first push end 1110 of the push clamping area 110 and is connected to the corresponding concave pressure cover 500; the second module baffle 800 is disposed at the second push end 1120 of the push clamping area 110 and is connected to the corresponding concave pressure cover 500. It can be understood that by disposing the first module baffle 700 at the first push end 1110 of the push clamping area 110, since the first module baffle 700 is connected to the corresponding concave pressure cover 500, the first push end 1110 of the push clamping area 110 can be blocked by the first module baffle 700, thereby preventing the battery module 400 from sliding out of the first push end 1110 of the push clamping area 110 during the lifting process. Furthermore, by providing a second module baffle 800 at the second push end 1120 of the push clamping area 110, since the second module baffle 800 is connected to the corresponding concave gland 500, the second module baffle 800 can block the second push end 1120 of the push clamping area 110, thereby preventing the battery module 400 from sliding out of the second push end 1120 of the push clamping area 110 during the lifting process. At the same time, it can prevent external impurities from entering the interior of the assembly structure, thereby reducing the impact of the external environment on the internal components.

[0041] like Figure 1 As shown, in this embodiment, the two ends of the first installation tie bar 610 are respectively extended to connect to the first side of the first module baffle 700 and the first side of the second module baffle 800; the two ends of the second installation tie bar 620 are respectively extended to connect to the second side of the first module baffle 700 and the second side of the second module baffle 800. It can be understood that because the first side of the first module baffle 700 and the first side of the second module baffle 800 are connected by the first installation tie bar 610, and the second side of the first module baffle 700 and the second side of the second module baffle 800 are connected by the second installation tie bar 620, the first installation tie bar 610 and the second installation tie bar 620 can effectively tighten the battery module 400, thereby achieving the fastening of the battery module 400, thereby ensuring the close combination of the internal components of the battery module 400, preventing loosening or displacement during use or transportation, and ensuring the safety and stability of the battery module 400.

[0042] Combination Figure 1 As shown, specifically, the first module baffle 700 is provided with a plurality of first heat dissipation holes 710, and the first heat dissipation holes 710 are used to be opposite to the first electrode end of the battery module 400; the second module baffle 800 is provided with a plurality of second heat dissipation holes 810, and the second heat dissipation holes 810 are used to be opposite to the second electrode end of the battery module 400. It can be understood that by providing heat dissipation holes on the first module baffle 700 and the second module baffle 800, because the first heat dissipation holes 710 are opposite to the first electrode end of the battery module 400, the heat of the battery module 400 can be quickly discharged through the first heat dissipation holes 710, and at the same time, the second heat dissipation holes 810 are opposite to the second electrode end of the battery module 400, so that the heat of the battery module 400 can be quickly discharged through the second heat dissipation holes 810, so that the heat generated by the battery module 400 during operation is effectively dissipated, thereby reducing the accumulation of heat inside the battery module 400, so as to reduce the safety risk caused by overheating.

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, the battery module assembly structure 10 further includes a plurality of assembly lugs 900, and a plurality of mounting holes 120 are provided at the peripheral position of the battery cell placement base plate 100; the assembly lugs 900 are arranged on the battery cell placement base plate 100 and are threadedly connected to the mounting holes 120. It can be understood that by arranging the assembly lugs 900 on the battery cell placement base plate 100 and threadedly connected to the mounting holes 120 at the peripheral edge of the base plate, when the battery module 400 is hoisted or installed, it is only necessary to align and connect the lugs with the brackets or mounting points of the corresponding equipment to complete the fixation, without the need for complex tools or additional support structures. This assembly method can simplify the installation process, save time and labor costs, and improve the accuracy of the installation.

[0044] Combination Figure 1 and Figure 2 As shown, further, the assembly lug 900 is provided with a hanging assembly port 910. It can be understood that by providing the hanging assembly port 910 in the assembly lug 900, it is more convenient to use a sling or a hook to pass through the hanging assembly port 910 during the hanging operation, so as to stably lift the battery module 400 and place it in the desired position. The hanging assembly port 910 is provided to increase the stability of the hanging, avoid the hook from sliding or misaligning, and improve the safety and reliability of the hanging process. At the same time, the existence of the hanging assembly port 910 also simplifies the steps of the hanging operation, reduces possible human errors, and further improves the efficiency of the hanging.

[0045] Please also read Figure 1 and Figure 4 The present disclosure also provides a heavy-duty energy storage box, including the battery module assembly structure 10 of any of the above-mentioned embodiments. It can be understood that by clamping the battery module 400 by the first limiting guide rail 200 and the second limiting guide rail 300, not only can the vertical shaking of the battery module 400 during hoisting and transportation be effectively reduced, but also the displacement or misalignment of the battery module 400 during the assembly process can be prevented. At the same time, by each concave pressure cover 500 pressing against a battery module 400, the battery module 400 can be pressed against the bottom plate, thereby clamping and fixing each battery module 400, so that the two adjacent groups of battery modules 400 are not easy to collide and rub against each other, which can reduce the scattering of each battery module 400 during the hoisting process, thereby improving the stability of the above-mentioned battery module assembly structure 10.

[0046] Compared with the prior art, the present invention has at least the following advantages:

[0047] 1) By fixing the first limiting guide rail 200 and the second limiting guide rail 300 at the opposite side edges of the battery cell placement base plate 100, a pushing clamping area 110 can be formed between the first limiting guide rail 200 and the second limiting guide rail 300. When the battery module 400 needs to be installed, the battery module 400 can be pushed into the pushing clamping area 110 from the first pushing end 1110. The battery module 400 can be moved and clamped between the first limiting guide rail 200 and the second limiting guide rail 300, so that the battery module 400 can be kept in a constrained state in the vertical direction. At the same time, because each concave pressure cover 500 is arranged opposite to a battery unit of the battery module 400, by fixing the first end of each concave pressure cover 500 to the first limiting guide rail 200, and fixing the second end of each concave pressure cover 500 to the second limiting guide rail 300, each concave pressure cover 500 can be securely covered on the battery module 400 to press and fix the battery module 400.

[0048] 2) Compared with the liquid-cooled battery pack and energy storage system of the prior art, the battery module assembly structure 10 clamps the battery module 400 through the first limiting guide rail 200 and the second limiting guide rail 300, which can not only effectively reduce the lateral shaking of the battery module 400 during hoisting and transportation, but also prevent the battery module 400 from being offset or misaligned during the assembly process. At the same time, each concave pressure cover 500 is pressed against a battery cell of the battery module 400, so that the battery module 400 can be pressed against the bottom plate, thereby clamping and fixing each battery module 400, so that the two adjacent groups of battery modules 400 are not easy to collide and rub against each other, which can reduce the occurrence of scattering of each battery module 400 during the hoisting process, thereby improving the stability of the above-mentioned battery module assembly structure 10.

[0049] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
