[0021] The following describes in detail the two embodiments of the present application with reference to the drawings.

[0022] The first embodiment:

[0023] Figures 1-6 Disclosed is a new energy lithium iron phosphate battery pack, which includes a first moving frame 1 and a second moving frame 2. A plurality of combined frames 3 are placed in a fitting manner between the first moving frame 1 and the second moving frame 2. A pair of insertion holes 7 are opened on the second moving frame 2, a pair of support holes 8 are opened on the combined frame 3, a pair of docking grooves 6 are opened at the side end of the first moving frame 1, a vertical groove 4 communicating with the insertion hole 7 is opened at one end of the second moving frame 2 away from the combined frame 3. A pair of reinforcing pipes 9 are fixedly connected to the inner top wall of the vertical groove 4. The outer ends of the pair of reinforcing pipes 9 are slidably sleeved with the same limiting block 10. A circular pipe 11 is movably inserted into the insertion hole 7. A plurality of combined pipes 12 are arranged on one side of the circular pipe 11. The plurality of combined pipes 12 are threadedly connected end to end, and one of the combined pipes 12 at one end is threadedly connected to the circular pipe 11. A limiting groove 14 for movably inserting the limiting block 10 is opened at the upper end of the circular pipe 11. A battery 5 is placed in a fitting manner on the upper end of the combined frame 3;

[0024] The combined pipe 12 movably penetrates through the support hole 8, and the end of the combined pipe 12 farthest from the circular pipe 11 extends out of the support hole 8 and is inserted into the docking groove 6. A pair of adjustment grooves 15 are opened at the upper end of the limiting block 10. A compression spring 16 is sleeved on the outer end of the reinforcing pipe 9. The ends of the first moving frame 1 and the second moving frame 2 close to each other are both in contact with the outer end of the battery 5. In the initial state, the compression spring 16 is in a contracted state. The lower end of the compression spring 16 is fixedly connected to the upper end of the limiting block 10, and the inner diameter of the compression spring 16 is larger than the diameter of the adjustment groove 15.

[0025] During use, according to the number of batteries 5 to be installed, take the corresponding number of combined frames 3, and then place the first moving frame 1 and the second moving frame 2 at both ends of the combined frame 3 respectively, so that the two ends of the first and last combined frames 3 are in close contact with the first moving frame 1 and the second moving frame 2 respectively, thereby installing the combined frames 3 corresponding to the number of batteries 5 on the first moving frame 1 and the second moving frame 2. Then select the corresponding number of combined pipes 12 according to the number of combined frames 3, thread them together, and thread one of the combined pipes 12 at the end to the circular pipe 11. After assembling the combined pipes 12, pass the combined pipes 12 through the insertion holes 7 into the support holes 8, and one end of one of the combined pipes 12 will penetrate through the support hole 8 and be inserted into the docking groove 6. At this time, the circular pipe 11 is inserted into the insertion hole 7. Under the elastic force of the compression spring 16, the lower end of the limiting block 10 is inserted into the limiting groove 14 to fix the circular pipe 11 in the insertion hole 7. Finally, place the battery 5 on the combined frame 3 and clamp the battery 5 through the first moving frame 1 and the second moving frame 2. The combined pipes 12 are used to improve the load-bearing capacity of the combined frame 3 and the stability between the combined frame 3, the first moving frame 1 and the second moving frame 2;

[0026] In summary, the battery pack not only has simple installation steps, but also is convenient for personnel to install different numbers of batteries 5.

[0027] The second implementation method:

[0028] On the basis of the first embodiment, this embodiment newly adds structures such as the fixed plate 17, and the rest is the same as the first embodiment.

[0029] Figure 5 It is shown that reinforcing plates 17 are fixedly connected to the side ends of the first moving frame 1, the second moving frame 2, and a part of the combined frame 3, and a reinforcing groove 13 is formed in the other side end of the other part of the combined frame 3. (As shown in Figure 5 shown, in order to improve the stability after splicing of multiple combined frames 3 and to connect multiple combined frames 3 together, a reinforcing plate 17 is provided at the left end of a part of the combined frame 3, and a reinforcing plate 17 is provided at the right end of the other part of the combined frame 3), magnetic coating one 18 is coated on both the inner top wall and the inner bottom wall of the reinforcing groove 13, and magnetic coating two 19 is coated on both the upper and lower ends of the reinforcing plate 17.

[0030] Insert the reinforcing plate 17 into the reinforcing groove 13 to install the first moving frame 1 and the second moving frame 2 on the combined frame 3 and to splice multiple combined frames 3 together. Reinforcing grooves 13 are formed at both ends of one of the combined frames 3. After the reinforcing plate 17 is inserted into the reinforcing groove 13, the stability of the joints of multiple combined frames 3, the first moving frame 1, and the second moving frame 2 can be improved, and at the same time, the load-bearing capacity of the combined frame 3 can be further improved. When the reinforcing plate 17 enters the reinforcing groove 13, the magnetic coating one 18 will be adsorbed to the magnetic coating two 19, thereby improving the stability of the reinforcing plate 17 in the reinforcing groove 13.

[0031] Combined with the current actual requirements, the above-mentioned embodiments adopted in this application are not limited to this. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
