Specifically, the first fixing block 8 and the second fixing block 10 are both provided with at least one first limiting portion 11, and the first fixing belt 7 and the second fixing belt 9 are both provided with at least one second limiting portion 12. The first limiting portion 11 and / or the second limiting portion 12 are in one-to-one contact with the side surfaces of the corresponding batteries, such as Figure 3 As shown, three first limiting portions 11 are arranged on the first fixing block 8 on the first fixing belt 7 of the present application, and one second limiting portion 12 is arranged on the first fixing belt 7, for a total of four limiting portions, which abut against the four sides of the battery to limit the battery.

The four first limiting parts 11 are in contact with the four sides of the battery to achieve the limiting of the battery. The first limiting parts 11 on the first fixed block 8 and the second fixed block 10 and the second limiting parts 12 on the first fixed belt 7 and the second fixed belt 9 can be adjusted according to actual needs. The number of the first limiting parts 11 and the second limiting parts 12 is four in total, corresponding to the four sides of the battery. The four limiting parts are in contact with the four sides to achieve stable limiting of the battery. Among them, the battery can be limited according to actual needs, or only the two opposite sides of the battery can be limited (one first limiting part 11, one second limiting part 12, or two first limiting parts 11, or two second limiting parts 12), and the battery can be prevented from moving in the horizontal direction and moving up and down by the clamping force of the two sides.

[0033] In one embodiment, the first fixing strap 7 and the second fixing strap 9 each include a fixing body 13 and first connecting ears 14 disposed at both ends of the fixing body 13, second connecting ears 15 are disposed on two opposite side walls of the battery base 1, the first connecting ears 14 are bolted to the corresponding second connecting ears 15, and the first fixing strap 7 and the second fixing strap 9 are both made of elastic metal material.

Figure 1 , Figure 2 and Figure 7Specifically, the first connecting ear 14 and the second connecting ear 15 are connected by bolts, and the first fixing belt 7 and the second fixing belt 9 are both made of elastic metal materials. Therefore, when the battery needs to be removed from the battery box device, it is only necessary to remove the bolts on one of the first connecting ears 14, and then lift the first fixing belt 7 or the second fixing belt 9 upward, so that the first fixing belt 7 and the second fixing belt 9 produce elastic deformation, and the battery can be taken out. It is not necessary to remove all the bolts on the two first connecting ears 14 on both sides of the fixed body 13, which can improve the disassembly efficiency and installation efficiency.

Specifically, the first limiting portion 11 and / or the second limiting portion 12 are correspondingly arranged around the first positioning surface 17 and the second positioning surface 18. Figure 3 As shown, there are three first limiting parts 11 and one second limiting part 12, and the three first limiting parts 11 and one second limiting part 12 all extend downward along the height direction (Z direction) of the battery. Therefore, a first limiting groove 19 is formed between the first positioning surface 17 and the corresponding first limiting part 11 and second limiting part 12. The top of the battery is accommodated in the first limiting groove 19, and the side surface of the battery abuts against the four limiting parts to limit the battery and prevent the battery from moving in the horizontal direction.

Similarly, Figure 4 As shown, there are two first limiting portions 11 and two second limiting portions 12, and the two first limiting portions 11 and the two second limiting portions 12 all extend downwardly along the Z direction. Therefore, a second limiting groove 20 is formed between the second positioning surface 18 and the corresponding first limiting portions 11 and second limiting portions 12. The top of the battery is accommodated in the second limiting groove 20, and the side surfaces of the battery are abutted against the four limiting portions to limit the battery and prevent the battery from moving in the horizontal direction. The second positioning surface 18 limits the battery and prevents the battery from moving up and down.

The first groove width W1 of different first fixing blocks 8 is different. Therefore, different first fixing blocks 8 installed on the first fixing belt 7 can be set with different first groove widths W1, which can adapt to batteries of different widths, further improving the versatility of the battery box device. Similarly, the second fixing block 10 is detachably arranged on the second fixing belt 9, and a second groove width W2 is formed on the second limiting groove 20 along the width direction (X direction) of the battery. The second groove width W2 of different second fixing blocks 10 is different. Therefore, different second fixing blocks 10 installed on the second fixing belt 9 can be set with different second groove widths W2, which can adapt to batteries of different widths, further improving the versatility of the battery box device.
