Further, the first pre-deformation assembly 200 includes a plurality of deformation units disposed on the rack 100, and the deformation units include: the fixing seat 210 is fixedly connected with the frame body 100; the first abutting member 220 is rotatably connected to the fixing base 210, and the first abutting member 220 rotates relative to the fixing base 210 to abut against or separate from the battery tray 400.
Further, the second pre-deformation assembly 300 comprises: a fixing frame 310 fixedly connected with the frame body 100; the second abutting member 320 is slidably connected to the fixing frame 310, and the second abutting member 320 slides relative to the fixing frame 310 to abut against or separate from a side of the battery tray 400 away from the first abutting member 220.
Specifically, as shown in fig. 1, the first abutment 220 in the deforming unit presses the battery tray 400 downward from above the battery tray 400, and the second abutment 320 in the second pre-deforming assembly 300 applies force upward to the battery tray 400, so that the battery tray 400 is pre-deformed.
