[0020] When in use, select a suitable battery positioning assembly according to the model and quantity of the battery 41, move the battery positioning assembly to a suitable position in the battery mounting frame 11 and fix it with bolts, then place the battery 41 in the battery positioning assembly, and then adjust the size of the fixing assembly 31 to fix the battery 41.

[0021] As attached Figure 1 As shown, in this embodiment, the battery mounting frame 11 and the plastic frame cover 12 are fastened by two locking knobs 14, which play the role of waterproofing, anti-corrosion, and anti-foreign impact on the battery 41 and other electrical components arranged inside. The side plate 35 of the battery mounting frame 11 has a number of weight-reducing holes, and a plastic lightweight baffle 36 is attached to the inside. The lightweight baffle 36 here is made of hard plastic. The strength meets the use requirements and can reduce the overall weight of the device. The baffle is fixed by a buckle. The battery mounting frame 11 is directly fixed to the longitudinal beam 13 of the vehicle. In order to increase the connection strength, protective plates 34 are added on both sides of the opening at the connection.

[0022] As attached Figure 2 and Figure 3 As shown, in this embodiment, the battery positioning assembly includes two battery mounting seats 21, and bosses are arranged at intervals at the bottom of the battery mounting outer frame 11. The bosses here are similar to the structure of steps. The battery mounting seat 21 is overlapped between the two bosses, and the battery mounting seat 21 moves along the length direction of the bosses and contacts the beam plate at the bottom of the battery mounting outer frame 11.

According to the installed battery 41 and the position of the battery mounting base 21, the fixing assembly 31 is adjusted, the second bolt is fixed, and the first plate and the second plate at both ends are rotated until a suitable size spacing is reached, and then the first screw 33 on the plate is aligned with the threaded hole on the bottom beam plate of the battery mounting outer frame 11. In actual production, the beam plate is opened with a threaded through hole. The first screw 33 and the threaded through hole are rotated to match and fix until the pressure plate 32 and the battery are in contact and squeezed. Here, a rubber pad can be set on the pressure plate 32, and the contact pressure force can make a certain friction between the battery 41 and the pressure plate 32. The value of the friction is determined according to the design and installation, and the premise is to ensure the normal use of the battery.
