The household energy storage battery with a stacking structure is intended to solve the technical problems in the prior art that multiple energy storage batteries are difficult to stack and are prone to heat generation after stacking, which affects safety.

[0027] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0028] A household energy storage battery with a stacking structure includes a battery body 1 and a fastening ring 2. The fastening ring 2 is sleeved on the outside of each two adjacent groups of battery bodies 1. The fastening ring 2 is divided into longitudinal and transverse types, and the longitudinal and transverse fastening rings 2 have the same structure. The longitudinal and transverse fastening rings 2 are used alternately as the battery bodies 1 are continuously stacked.

[0029] First, see Figure 1 、 Figure 2 and Figure 3 , the specific structure of the fastening ring 2 is as follows;

[0030] The fastening ring 2 includes a horizontal bar 201, a vertical bar 202, a connecting rod 203, a collar 204, a bolt 205 and a nut 206. The horizontal bar 201 is movably connected to the bottom of the battery body 1. The two groups of vertical bars 202 are respectively rotatably connected to the two ends of the horizontal bar 201. The connecting rod 203 is rotatably connected to the top of the vertical bar 202. The collar 204 is fixedly connected to the end of the connecting rod 203 away from the vertical bar 202. The bolt 205 is sleeved on the inner side of the two groups of collars 204. The nut 206 is threadedly connected to the top of the bolt 205.

[0031] During use of the present invention, first, the two groups of battery bodies 1 are stacked and placed above the cross bar 201, and then the bolt 205 is placed in the middle of the top of the battery body 1, and then the vertical rods 202 at the front and rear ends are rotated and erected, and then the connecting rod 203 is rotated. The two groups of connecting rods 203 drive the two groups of rings 204 to move closer to the middle of the top of the battery body 1, so that the two groups of rings 204 overlap at the top of the battery body 1 and are sleeved onto the outside of the bolt 205, and the nut 206 is threadedly connected to the top of the bolt 205, and then the nut 206 is tightened, so that the two groups of battery bodies 1 are stacked firmly.

[0032] For further information, see Figure 1 、 Figure 3 、 Figure 4 and Figure 5 , grooves 3 are provided in the longitudinal and transverse directions on the top of the battery body 1. The width of the groove 3 is equal to the width of the connecting rod 203. The longitudinal and transverse grooves 3 can facilitate the fastening ring 2 to be sleeved on the battery body 1 from different directions. A circular groove 4 is provided at the top of the battery body 1 and at the intersection of the two sets of grooves 3. The interior of the circular groove 4 is convenient for placing bolts 205, nuts 206 and two sets of rings 204, and the depth of the circular groove 4 is greater than the height of the bolt 205. A hexagonal groove 5 is provided at the center of the circular groove 4. The bottom of the bolt 205 is engaged with the hexagonal groove 5. The hexagonal groove 5 is used to stabilize the bolt 205 and facilitate the screwing of the nut 206.

[0033] For further information, see Figure 1 、 Figure 4 and Figure 5The top of the battery body 1 is provided with four groups of positioning grooves 6, and the bottom of the battery body 1 is fixedly connected with four groups of positioning columns 7. The positioning columns 7 are engaged with the positioning grooves 6, so that the stacking of the upper and lower groups of battery bodies 1 is stable. A stabilizing foot 8 is fixedly connected to the middle of the bottom of the battery body 1. Stabilizing grooves 9 are provided around the stabilizing foot 8. The cross bar 201 is engaged with the stabilizing grooves 9 to ensure that the cross bar 201 does not move, so that the fastening ring 2 is more firmly connected to the upper and lower groups of battery bodies 1. The height of the stabilizing foot 8 is equal to the height of the positioning column 7. When the battery body 1 is placed on the ground, the stabilizing foot 8 and the positioning column 7 can support the battery body 1 at the same time. The height of the positioning column 7 is greater than the depth of the positioning groove 6, so that there is a gap in the middle of the upper and lower groups of battery bodies 1 after stacking, which can ensure air circulation, and the stabilizing foot 8 is engaged with the circular groove 4, which can help increase the stability of the stacking between the battery bodies 1.

[0034] For further information, see Figure 1 、 Figure 4 and Figure 5 Two groups of card strips 10 are fixedly connected to the front of the battery body 1, and two groups of card slots 11 are opened on the back of the battery body 1. The card strips 10 are connected with the card slots 11, and the depth of the card slots 11 is less than the thickness of the card strips 10, so that there is a gap in the middle of the battery body 1 when it is laid flat, which can ensure air circulation and facilitate the removal of heat.

[0035] For further information, see Figure 1 、 Figure 4 and Figure 5 Square grooves 12 are provided on the left and right ends of the top of the battery body 1. The inner side of the square grooves 12 is fixedly connected to a terminal post 13, which is used to connect the wires. The square grooves 12 can ensure that after the terminal post 13 is connected to the wires, it will not hinder the stacking of the battery body 1. Finger grooves 14 are provided on the left and right sides of the battery body 1, which can facilitate the transportation of the battery body 1.

[0036] The working process of this utility model:

[0037] During use of the present invention, the first battery body 1 is first placed on top of the cross bar 201 of the longitudinal fastening ring 2, and the cross bar 201 is snapped into the stabilizing groove 9, and then the second battery body 1 is placed on top of the cross bar 201 of the transverse fastening ring 2, and then the second battery body 1 together with the transverse fastening ring 2 is stacked on top of the first battery body 1, and the positioning column 7 is snapped into the positioning groove 6, and the stabilizing foot 8 is snapped into the circular groove 4, and then the bolt 205 is snapped into the hexagonal groove 5 at the top of the second battery body 1, and then the vertical rods 202 at both ends of the longitudinal fastening ring 2 are rotated and erected, and then the connecting rod 203 is rotated, and both sets of connecting rods 203 are connected. Move the two sets of collars 204 toward the middle of the top of the battery body 1 so that the two sets of collars 204 overlap at the top of the battery body 1 and are sleeved onto the outside of the bolt 205. Thread the nut 206 onto the top of the bolt 205 and tighten the nut 206 to firmly stack the two sets of battery bodies 1. Then, stack the third set of battery bodies 1 on top of the second set of battery bodies 1. Repeat the above steps and stack them continuously. The longitudinal and transverse fastening rings 2 are used alternately as the battery bodies 1 are stacked continuously. The multiple sets of battery bodies 1 are connected by the positioning columns 7 and the positioning grooves 6 to ensure the stability of the stacking of the multiple sets of battery bodies 1.

[0038] At the same time, the height of the positioning column 7 is greater than the depth of the positioning groove 6, so that there is a gap in the middle of each two groups of battery bodies 1 after stacking, and the depth of the card slot 11 is less than the thickness of the card strip 10, so that there is a gap in the middle of the battery body 1 when it is laid flat, which can ensure air circulation and facilitate the removal of heat. It can prevent the battery bodies 1 from being overheated when stacked together for use, thereby ensuring safety during use.
