Technical Field

[0001] The present disclosure relates to the field of battery modules, and particularly to a lithium battery module with convenient disassembly and assembly and a household energy storage device. Background Art

[0002] Batteries in the new energy industry usually need to be supported and installed through a battery energy storage box, while ensuring electrical isolation and safety protection performance. In order to increase the capacity of the battery, multiple battery boxes are usually spliced together. Each battery box is provided with battery cells, and the battery cells in adjacent two battery boxes are electrically connected, thereby increasing the electricity storage capacity of the battery.

[0003] For example, Chinese Patent No. CN202310978046.X discloses a stacked connection structure of a power energy storage battery box, including a vertical stacking frame. The vertical stacking frame includes two side frames and a fixing frame. The two side frames are fixedly connected through the fixing frame. A plurality of supporting modules are rotatably connected inside the vertical stacking frame and are distributed from top to bottom in sequence. The supporting module includes a tray, two connector holders and a wire bundling cylinder.

[0004] The above-mentioned power energy storage battery box can separate the energy storage battery boxes on the same layer through the vertical stacking frame and the independently existing supporting modules inside, so that a plurality of energy storage battery boxes on the same layer are positioned and constrained on different trays to fix the plurality of battery boxes. However, since a plurality of battery boxes need to be placed in the corresponding frames for assembly, the convenience of battery assembly is poor, and due to the fixed frame, the overall structure of the battery is relatively bulky, which is not conducive to compact design.

[0005] Therefore, there is an urgent need for a battery box structure with relatively convenient disassembly and assembly and a relatively compact structure. Summary of the Utility Model

[0006] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a lithium battery module with convenient disassembly and assembly and a household energy storage device with relatively convenient disassembly and assembly and a relatively compact structure.

The battery box at the bottom is embedded in the embedding groove. A clamping post is provided at the bottom of each battery box. A clamping groove is provided at the top of the battery box. The clamping posts and the clamping grooves of adjacent two battery boxes are correspondingly arranged so that adjacent two battery boxes are clamped;

[0010] The lithium battery module further includes a fixing component, the fixing component includes a fixing plate and at least two fasteners. Each battery box is provided with a first connection hole, the fixing plate is provided with a second connection hole, the second connection holes are respectively arranged corresponding to the first connection holes of two adjacent battery boxes, and the fasteners sequentially pass through the second connection holes and the first connection holes to connect two adjacent battery boxes.

[0011] In one embodiment, the number of the clamping posts is multiple, the number of the clamping grooves is multiple, the multiple clamping posts are evenly distributed at the bottom of the battery box, and the multiple clamping grooves are evenly distributed at the top of the battery box.

[0012] In one embodiment, the height of the clamping post is consistent with the depth of the clamping groove.

[0013] In one embodiment, each battery box is provided with a receiving groove, and two adjacent receiving grooves together form a receiving cavity. The fixing plate is located in the receiving cavity and is respectively connected to the two battery boxes.

[0014] In one embodiment, the fixing plate is flush with the sides of two adjacent battery boxes.

[0015] In one embodiment, the number of the fixing components is multiple, and the multiple fixing components are evenly distributed on the peripheries of two adjacent battery boxes.

And because the above two connection methods are relatively convenient to operate, the disassembly and assembly convenience of the plurality of battery boxes during assembly is improved. On the other hand, since there is no need to additionally add a fixing frame to fix the battery boxes, the overall structural compactness of the battery module is higher.

[0031] To better understand the technical solutions and beneficial effects of the present disclosure, the following further describes the present disclosure in detail with specific embodiments:

[0032] As Figures 1 to 3 shown, a lithium battery module 10 with convenient disassembly and assembly in an embodiment includes a bottom cover 100, a plurality of battery boxes 200 and a fixing component 300. The bottom cover 100 is provided with an embedding groove (not shown in the figure). The plurality of battery boxes 200 are stacked. The battery box 200 at the bottom is embedded in the embedding groove. A clamping post 210 is provided at the bottom of each battery box 200, and a clamping groove 220 is provided at the top of the battery box 200. The clamping posts 210 and the clamping grooves 220 of two adjacent battery boxes 200 are correspondingly arranged so that two adjacent battery boxes 200 are clamped to preliminarily fix two adjacent battery boxes 200.

[0033] Further, the fixing component 300 includes a fixing piece 310 and at least two fasteners 320. Each battery box 200 is provided with a first connection hole (not shown in the figure). The fixing piece 310 is provided with a second connection hole (not shown in the figure). The second connection holes are respectively arranged corresponding to the first connection holes of two adjacent battery boxes 200. The fasteners 320 sequentially pass through the second connection holes and the first connection holes to connect two adjacent battery boxes 200, that is, two adjacent battery boxes 200 are further fixed by the fixing piece 310 and the fasteners 320.

[0034] In this embodiment, a battery cell is provided in each battery box 200. The fastener 320 is a screw. Two adjacent battery boxes 200 are initially fixed by a clamping post 210 and a clamping groove 220. Then, the second connection holes of the fixing piece 310 are respectively arranged corresponding to the first connection holes of two adjacent battery boxes 200. The fasteners 320 pass through the second connection holes and the first connection holes to further fix two adjacent battery boxes 200. Further, each battery box 200 is provided with an electrical connection head. Two adjacent electrical connection heads are electrically connected through a wire to electrically connect multiple battery boxes 200. The assembly process of the lithium battery module is as follows: The bottom battery box 200 is embedded in the embedding groove of the bottom cover 100. Then, multiple battery boxes 200 are sequentially stacked, and the clamping posts 210 of two adjacent battery boxes 200 are clamped with each other. Finally, two adjacent battery boxes 200 are locked by the fasteners 320 and the fixing piece 310.

[0035] For the above lithium battery module 10 with convenient disassembly and assembly, multiple battery boxes 200 are stacked. A clamping post 210 is provided at the bottom of each battery box 200, and a clamping groove 220 is provided at the top. Two adjacent battery boxes 200 are clamped by the clamping post 210 and the clamping groove 220 to initially fix the two battery boxes 200. Further, the fasteners 320 pass through the second connection holes of the fixing piece 310 and the first connection holes of the battery boxes 200, so that two adjacent battery boxes 200 are connected by the fasteners 320 and the fixing piece 310 to further fix two adjacent battery boxes 200. And because the above two connection methods are relatively convenient to operate, the disassembly and assembly convenience of multiple battery boxes 200 during assembly is improved. On the other hand, since there is no need to additionally add a fixing frame to fix the battery boxes 200, the overall structural compactness of the battery module is higher.

[0036] Such as Figure 2 and Figure 3As shown, in one embodiment, the number of the clamping posts 210 is multiple, and the number of the clamping grooves 220 is multiple. The multiple clamping posts 210 are evenly distributed at the bottom of the battery box 200, and the multiple clamping grooves 220 are evenly distributed at the top of the battery box 200. In this embodiment, two adjacent battery boxes 200 are clamped and fixed through the clamping posts 210 and the clamping grooves 220, and the multiple clamping grooves 220 and the clamping posts 210 make the clamping between the battery boxes 200 more stable.

[0037] As Figures 1 to 3 shown, in one embodiment, the height of the clamping post 210 is consistent with the depth of the clamping groove 220. In this embodiment, the sizes of the clamping post 210 and the clamping groove 220 are adapted to each other, so that two adjacent battery boxes 200 are more closely attached, and further the structure of the battery module is more compact.

[0038] As Figure 1 shown, in one embodiment, each battery box 200 is provided with a receiving groove, and two adjacent receiving grooves together form a receiving cavity 230. The fixing piece 310 is located in the receiving cavity 230 and is respectively connected to the two battery boxes 200. In this embodiment, the receiving grooves of two adjacent battery boxes 200 communicate with each other to form the receiving cavity 230, and the fixing effect of the fixing piece 310 located in the receiving cavity 230 is better.

[0039] In one embodiment, the fixing piece 310 is flush with the sides of two adjacent battery boxes 200. It can be understood that the thickness of the fixing piece 310 is consistent with the thickness of the receiving cavity 230, so that the fixing piece 310 is flush with the sides of the battery box 200, and further the structure of the battery module is more flat.

[0040] As Figure 1 shown, in one embodiment, the number of the fixing assemblies 300 is multiple, and the multiple fixing assemblies 300 are evenly distributed on the peripheries of two adjacent battery boxes 200. It can be understood that two adjacent battery boxes 200 are fixed by the multiple fixing assemblies 300, so that the fixing effect of the battery boxes 200 is more stable.

[0041] As Figure 2 and Figure 3 shown, in one embodiment, the periphery of the battery box 200 is provided with a grasping groove 240. In this embodiment, the grasping grooves 240 are provided on both sides of the battery box 200, and the two grasping grooves 240 are arranged correspondingly. The grasping groove 240 is used to accommodate the palm and fingers, so that the handling of the battery box 200 is more convenient.

[0042] As Figure 1As shown, in one embodiment, the lithium battery module further includes a pulley 400, and the pulley 400 is connected to a side surface of the bottom cover 100 away from the battery box 200. In this embodiment, the pulley 400 is fixedly connected to the bottom cover 100, making it more convenient to handle the assembled battery module during transportation.

[0043] In one embodiment, the lithium battery module further includes a screwing member (not shown in the figure). The pulley 400 is provided with a first screwing hole, and the bottom cover 100 is provided with a second screwing hole. The screwing member sequentially passes through the first screwing hole and the second screwing hole to screw the pulley 400 to the bottom cover 100. In this embodiment, the screwing member is a screw, and the pulley 400 and the bottom cover 100 are fixedly screwed by the screw, which is convenient for disassembly and assembly of the pulley 400.

[0044] This application also provides a household energy storage device, including the lithium battery module 10 with convenient disassembly and assembly described in any of the above embodiments.

[0045] Compared with the prior art, the present disclosure has at least the following advantages:

[0046] For the above-mentioned lithium battery module 10 with convenient disassembly and assembly, a plurality of battery boxes 200 are stacked. A clamping post 210 is provided at the bottom of each battery box 200, and a clamping groove 220 is provided at the top. Two adjacent battery boxes 200 are clamped by the clamping post 210 and the clamping groove 220 to preliminarily fix the two battery boxes 200. Further, a fastener 320 passes through the second connection hole of the fixing piece 310 and the first connection hole of the battery box 200 to connect two adjacent battery boxes 200 through the fastener 320 and the fixing piece 310, further fixing two adjacent battery boxes 200. And because the above two connection methods are relatively convenient to operate, the disassembly and assembly convenience of a plurality of battery boxes 200 during assembly is improved. On the other hand, since there is no need to additionally increase a fixing frame to fix the battery box 200, the overall structural compactness of the battery module is higher.

[0047] The above embodiments only represent several implementation manners of the present disclosure, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several deformations and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
