[0009] As a preferred embodiment of the utility model, the wall surface of the edge guard is also provided with a connecting structure, which includes a locking groove, a spring groove and a pull groove. The locking groove is symmetrically opened on the rear wall surface of the edge guard, the spring groove is symmetrically opened in the locking groove, and the pull groove is also opened on the rear wall surface of the edge guard.

[0010] As a preferred embodiment of the present utility model, the locking groove is an arrow-shaped groove, the spring grooves are symmetrically arranged on both sides of the locking groove, and the pulling groove can be connected to the spring groove.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a stacked battery pack includes a base 20, a side guard 21 is clamped on the top of the base 20, the side guard 21 is in the shape of a rounded rectangular frame, a bottom plate 22 is fixedly connected to the cavity of the side guard 21, a battery block 23 is clamped in the cavity of the side guard 21, universal wheels are installed at the bottom of the base 20, and a rectangular groove is also opened on the rear wall of the side guard 21, and the wires of the battery block 23 can pass through the rectangular groove behind the side guard 21. This is the prior art and will not be described in detail here.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the wall surface of the edge guard 21 is provided with a disassembly structure, and the disassembly structure includes a splitting groove 30, a base shaft 31, a live edge 32 and a clamping block 33. The splitting groove 30 is opened on one side wall surface of the edge guard 21, the base shaft 31 is fixedly connected to the wall surface of the edge guard 21 at the splitting groove 30, the live edge 32 and the base shaft 31 are rotationally connected, and the clamping block 33 is symmetrically rotationally connected to the wall surface of the edge guard 21 at the splitting groove 30, and the battery block 23 can be disassembled from the splitting groove 30.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the battery block 23 is in the cavity of the edge guard 21, its bottom can contact the top of the bottom plate 22, the size of the live edge 32 is consistent with the splitting groove 30, the clamping block 33 is capsule-shaped, the base axis 31 is between the symmetrical clamping blocks 33, the wall surface of the base axis 31 can contact the live edge 32, the top of the edge guard 21 is fixedly connected with an alignment plate 24, the bottom of the edge guard 21 is provided with an alignment groove 25, the alignment plate 24 is an arc-shaped plate, the alignment groove 25 can adapt to the size of the alignment plate 24, there are four alignment plates 24 evenly distributed at the four corners of the top of the edge guard 21, and the position and number of the alignment grooves 25 are aligned with the alignment plate 24;

[0028] During specific use, the top of the base 20 is also fixedly connected with an alignment plate 24 and a locking block 45. The battery pack to be stacked is placed on the top of the base 20 through the edge guard 21. At this time, the alignment plate 24 on the top of the base 20 can enter the alignment groove 25 at the bottom of the edge guard 21 at its top, and the locking block 45 can enter the locking groove 40. When the locking block 45 enters the locking groove 40, the top of the locking block 45 can push the symmetrical spring block 43, and the spring block 43 will slide in the spring groove 41. The spring in the spring groove 41 will be compressed. When the top of the locking block 45 enters the locking groove 40, the spring will push the spring block 43 to the two sides of the locking block 45 to fix the position. The edge guards 21 to be stacked are also connected and fixed to the edge guards 21 on the top of the base 20 in this way. When a single battery block 23 needs to be removed from the cavity of the edge guard 21, the wires connecting the multiple battery blocks 23 are first disconnected, and then the clamping block 33 is rotated ninety degrees. At this time, the wall surface of the clamping block 33 is no longer in contact with the outer wall surface of the live edge 32. The live edge 32 can thus be flipped along the base axis 31. After the live edge 32 is flipped, the splitting groove 30 will be in an open state. At this time, the battery block 23 can be directly taken out from the splitting groove 30. At this point, the removal of the single battery block 23 is completed. The battery block 23 is reinstalled into the cavity of the edge guard 21 and then put into the splitting groove 30, and then the live edge 32 is flipped and the clamping block 33 is rotated to complete the removal.

[0029] In summary, by setting up a disassembly structure, a single battery block 23 can be quickly removed from the cavity of the edge guard 21, because the disassembly structure opens one side of the edge guard 21 to remove the battery block 23 and can also remove the battery block 23 when multiple edge guards 21 are stacked together. Therefore, compared with the prior art, this solution is faster and more convenient when disassembling the battery block 23.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the wall surface of the edge guard 21 is also provided with a connecting structure, which includes a locking groove 40, an elastic groove 41 and a pull groove 42. The locking groove 40 is symmetrically arranged on the rear wall surface of the edge guard 21, the elastic groove 41 is symmetrically arranged in the locking groove 40, and the pull groove 42 is also arranged in the rear wall surface of the edge guard 21. The locking groove 40 is an arrow-shaped groove, and the elastic groove 41 is symmetrically arranged on both sides of the locking groove 40. The pull groove 42 can be connected to the elastic groove 41. The connecting structure also includes an elastic block 43, a pull block 44 and a locking block 45. The elastic block 43 is elastically connected in the elastic groove 41 through a spring. Then, the shift block 44 is fixedly connected to the wall of the spring block 43 facing the shift groove 42, and the locking block 45 is symmetrically fixedly connected to the top of the edge guard 21. One end of the spring block 43 can pass through the spring groove 41. The end of the spring block 43 that can pass through the spring groove 41 is a right triangle. The shift block 44 can pass through the shift groove 42. The spring can push the spring block 43 toward another symmetrical spring block 43. The locking block 45 is in the shape of an upward arrow. The locking groove 40 can adapt to the top of the locking block 45. The symmetrical locking blocks 45 and the symmetrical locking grooves 40 are vertically aligned.

[0031] When in use, the battery pack to be stacked is placed on the top of the bottom edge guard 21 through the edge guard 21. At this time, the alignment plate 24 on the top of the base 20 can enter the alignment groove 25 at the bottom of the edge guard 21 at the top of the base 20, and the locking block 45 can enter the locking groove 40. When the locking block 45 enters the locking groove 40, the top of the locking block 45 can push the symmetrical spring block 43, and the spring block 43 slides in the spring groove 41. The spring in the spring groove 41 will be compressed. When the top of the locking block 45 enters the locking groove 40, the spring will push the spring block 43 to the two sides of the locking block 45 to fix the position. When the stacked multiple edge guards 21 are separated, the shifting block 44 is shifted to slide in the shifting groove 42. At this time, the shifting block 44 can drive the spring block 43 to slide in the spring groove 41 and no longer clamp the locking block 45. At this time, the edge guard 21 can be removed from the top of another edge guard 21;

[0032] In summary, by setting up a connecting structure, multiple edge guards 21 can be quickly combined and fixed, because when stacking the edge guards 21, the connecting structure only needs to press the edge guard 21 and another edge guard 21 vertically to connect them together. This process does not require other steps to complete, so they can be quickly connected together, reducing work pressure and working time.

[0033] Working principle: the top of the base 20 is also fixedly connected with an alignment plate 24 and a locking block 45. The battery pack to be stacked is placed on the top of the base 20 through the edge guard 21. At this time, the alignment plate 24 on the top of the base 20 can enter the alignment groove 25 at the bottom of the edge guard 21 at the top of the base 20, and the locking block 45 can enter the locking groove 40. When the locking block 45 enters the locking groove 40, the top of the locking block 45 can push the symmetrical spring block 43, and the spring block 43 will slide in the spring groove 41, and the spring in the spring groove 41 will be compressed. When the top of the locking block 45 enters the locking groove 40, the spring will push the spring block 43 to the two sides of the locking block 45 to fix the position. When another set of edge guards 21 to be stacked is connected and fixed to the edge guard 21 on the top of the base 20 in this way, when the stacked multiple edge guards 21 are separated, the shift block 44 is shifted to slide in the shift groove 42. At this time, the shift block 44 can drive the spring block 43 to slide in the spring groove 41 and no longer clamp the locking block 45. At this time, the edge guard 21 can be removed from the top of another edge guard 21.
