The backup pad is made by the metal, through welded connection on 1 four corners of battery box layer board, and its height is leveled mutually with the height of the rectangular pipe in the battery box layer board, when making battery box 5 install on the battery layer board, battery box bottom plane can have good contact with the upper surface of battery box layer board.

As shown in fig. 2, the

support plates

2b, 2c, 2d have T-shaped grooves 21 and positioning V-shaped grooves 22 on the surfaces thereof. And is fixed on the supporting plate through a quick positioning and clamping device arranged on the supporting plate.

As shown in FIG. 3, the supporting plate 2a has a plurality of parallel mounting slots 23, which are connected to the clamping plate by mounting bolts in the mounting slots 23, and a circular hole 24 is formed at the end of each mounting slot 23 to facilitate the assembly and disassembly of the bolts on the supporting plate.

As shown in fig. 4, the clamping flap 3b is formed by joining metal parts shaped like an "L". The rapid clamping device comprises a vertical surface and a horizontal surface, wherein the bottom of the horizontal surface is provided with a plurality of V-shaped protrusions 31 and a rapid clamping device 32, the vertical surface is provided with a U-shaped groove 33, and one side of the U-shaped groove is provided with a trapezoidal groove 34. The V-shaped protrusion 31 is used for quickly attaching the clamping baffle 3b to the V-shaped groove 22 of the support plate, and fixing the clamping baffle 3b to the support plate by a quick clamping device. The trapezoidal groove 34 is used for enabling the battery box 5 to be attached to the positioning baffle conveniently and quickly, so that quick positioning is achieved, and the bolt penetrates through the U-shaped groove to lock the positioning baffle and the battery box.

As shown in fig. 5, the quick clamping device 32 is composed of a locking screw 321, two connecting rods 322, two locking hooks 323, and a fixing ring 324. The two connecting rods 322 are respectively hinged with the two lock hooks 323 and the connecting rods 322.
