The upper splicing sleeve has a splicing groove on its upper surface, and the lower splicing sleeve has a plug rod at its bottom that is used in conjunction with the splicing groove. Bolt grooves are provided on both sides of the outer ends of multiple battery boxes. A fixing plate is provided on the outside of the battery box, and fixing bolts are provided on both sides of the fixing plate. Two fixing bolts are respectively threaded into the bolt grooves on the outer sides of the two battery boxes. The splicing assembly enables the standardization, normalization, and material uniformity of the power module of high-power electric products, reducing costs and thus better promoting the market growth of power modules for high-power electric products. At the same time, the number of square batteries spliced can be adjusted according to different products.
[0007] Preferably, the upper splicing sleeve and the lower splicing sleeve are provided with a semi-circular arc on opposite sides, and the two semi-circular arcs are combined into a circular groove. A reinforcing bolt is provided on one side of the outer end of the fixing plate, and the reinforcing bolt is threadedly connected to the inside of the circular groove.

Detailed Implementation
[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0025] Example:
[0026] As attached Figure 1 To be continued Figure 8 As shown:
[0027] This utility model provides a novel square battery power module, including multiple battery boxes 1; the battery box 1 is equipped with a square battery inside, the multiple battery boxes 1 are equipped with a protective shell 2 outside, the protective shell 2 is equipped with a bottom plate 201 at the bottom, the protective shell 2 is equipped with a cover plate 206 at the top, the square battery is equipped with a splicing port 101 at the top, and the multiple battery boxes 1 are equipped with a splicing component.
[0028] The splicing components include: an upper splicing sleeve 3, a splicing groove 301, a lower splicing sleeve 4, and a plug rod 401. The upper splicing sleeve 3 is provided on the top of the battery box 1, and the lower splicing sleeve 4 is provided on the bottom of the battery box 1. The upper surface of the upper splicing sleeve 3 has a splicing groove 301, and the bottom of the lower splicing sleeve 4 has a plug rod 401 that is used in conjunction with the splicing groove 301. Bolt grooves 102 are provided on both sides of the outer end of the multiple battery boxes 1. A fixing plate 5 is provided on the outside of the battery box 1. Fixing bolts 501 are provided on both sides of the fixing plate 5, and the two fixing bolts 501 are respectively threaded into the bolt grooves 102 opened on the outside of the two battery boxes 1.
[0029] When two square batteries need to be spliced together, the two square batteries are first connected through the splicing port 101. During the connection process, the insertion rod 401 at the bottom of the lower splicing sleeve 4 will be inserted into the splicing groove 301 opened on the upper surface of the upper splicing sleeve 3, so that the two battery boxes 1 are spliced together. Then, two fixing plates 5 are placed on the outer surface of the battery box 1, and the fixing bolts on both sides of the fixing plate 5 are screwed into the bolt groove 102, so that the two battery boxes 1 can be fixedly connected, preventing the two battery boxes 1 from detaching and affecting the normal output of the square batteries. This enables the standardization, normalization, and material uniformity of the power module of high-power electric products, reduces costs, and better promotes the market growth of power modules for high-power electric products. At the same time, the number of square batteries spliced can be adjusted according to different products.
[0030] The upper splicing sleeve 3 and the lower splicing sleeve 4 each have a semi-circular arc 6 on their opposite sides. The two semi-circular arcs 6 merge into a circular groove. The outer end of the fixing plate 5 has a reinforcing bolt 502, which is threaded into the circular groove. After the two battery boxes 1 are spliced together, the semi-circular arcs 6 on their opposite sides will merge into a circular groove. Then, the reinforcing bolt 502 on the outer end of the fixing plate 5 is screwed into the circular groove, so that the reinforcing bolt 502 is threaded into the circular groove, thereby reinforcing the connection between the two battery boxes 1 and making the connection tighter.
[0031] The protective shell 2 has a support plate 7 at the bottom inside, and movable slots 202 on both sides of the outer end of the protective shell 2. Handles 701 are connected to both sides of the support plate 7, and the handles 701 pass through the movable slots 202 and extend to the outside of the protective shell 2. When multiple square batteries spliced together are outputting power, the protective shell 2 can protect the square batteries. When it is necessary to remove the square batteries, the cover plate 206 is removed, the staff steps on the bottom plate 201 of the protective shell 2 with both feet, and then grabs the handles 701 on both sides. By lifting the handles 701, the support plate 7 at the bottom inside the protective shell 2 is moved up, and the square batteries are moved upward by the support plate 7. At this time, the top of the square batteries is moved to the top of the protective shell 2, which makes it easier for the staff to remove the square batteries.
[0032] The protective shell 2 has multiple heat dissipation holes 203 on both sides of its outer end, and the holes 203 are equidistant from each other. A filter screen 204 covering the heat dissipation holes 203 is provided on both sides of the outer end of the protective shell 2. Mounting bolts 205 are provided on all four sides of the outer end of the filter screen 204, and mounting grooves matching the mounting bolts 205 are provided on both sides of the outer end of the protective shell 2. When the square battery is inside the protective shell 2, the heat generated during power output can be dissipated through the multiple heat dissipation holes 203 on both sides of the outer end of the protective shell 2, thus protecting the square battery while ensuring effective heat dissipation. Furthermore, the filter screen 204 covering the heat dissipation holes 203 prevents external dust from entering the protective shell 2, preventing dust accumulation at the square battery terminals and causing short circuits. The mounting bolts 205 on all four sides of the outer end of the filter screen 204 allow for easy removal and cleaning.
[0033] The specific usage and function of this embodiment are as follows:
[0034] When two square batteries need to be spliced together, the two square batteries are first connected through the splicing port 101. During the connection process, the insertion rod 401 at the bottom of the lower splicing sleeve 4 will be inserted into the splicing groove 301 opened on the upper surface of the upper splicing sleeve 3, so that the two battery boxes 1 are spliced together. Then, two fixing plates 5 are placed on the outer surface of the battery box 1, and the fixing bolts on both sides of the fixing plate 5 are screwed into the bolt groove 102, so that the two battery boxes 1 can be fixedly connected, preventing the two battery boxes 1 from detaching and affecting the normal output of the square batteries. This enables the standardization, normalization, and material uniformity of the power module of high-power electric products, reduces costs, and better promotes the market growth of power modules for high-power electric products. At the same time, the number of square batteries spliced can be adjusted according to different products.
[0035] When multiple square batteries are spliced together to output power, the protective shell 2 can protect the square batteries. When it is necessary to remove the square batteries, the cover plate 206 is removed, the staff steps on the bottom plate 201 of the protective shell 2 with both feet, and then grabs the handles 701 on both sides. By lifting the handles 701, the staff moves the support plate 7 at the bottom of the protective shell 2, and then uses the support plate 7 to move the square batteries upward. At this time, the top of the square batteries moves to the top of the protective shell 2, making it easier for the staff to remove the square batteries.
