Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1 and 2, a schematic view of an embodiment of a quick-change frame according to the present invention is shown. The utility model discloses a frame includes anticollision roof beam 1, energy-absorbing box 2, body frame 3 and power battery module 40, body frame 3 middle part is provided with and constitutes the rectangle frame by automobile body crossbeam 33 and automobile body longeron 34, energy-absorbing box 2 and anticollision roof beam 1 connect respectively in both ends around the rectangle frame, energy-absorbing box 2 and anticollision roof beam 1 loop through the bolt with body frame 3 links to each other, and anticollision roof beam 1 and energy-absorbing box 2 can effectively absorb the collision energy when the vehicle takes place the low-speed collision, reduce the impact as far as to preceding, back longeron 32's harm, through bolted connection between anticollision roof beam 1 and energy-absorbing box 2 and the body frame 3, the quick replacement of being convenient for, it is convenient to maintain. In order to realize quick replacement of the battery, in this embodiment, the bottom surfaces of two opposite sides of the power battery module 40 are provided with a plurality of lugs 41 extending outwards, the bottom portions of the opposite sides in the rectangular frame are provided with a carrying strip, the carrying strip is provided with a notch 342 matched with the lug 41, the carrying strip and the lug 41 on one side of the notch 342 are provided with threaded holes, and the carrying strip and the lug 41 are locked by bolts penetrating through the threaded holes. When hangers 41 and the carrying strip are locked, the power battery module 40 is carried by the frame, when the bolts are disassembled, the power battery module 40 can move freely and can be directly taken out from the upper part of the frame for replacement, if the power battery module 40 is inconvenient to take out from the upper part, the power battery module 40 can be pushed towards the gap 342, and therefore the power battery module 40 can be taken out from the lower part of the frame. The replacement and maintenance of the power battery module 40 are convenient.
Referring to fig. 2, in order to prevent the power battery module 40 from directly falling into the notch 342 when being placed on the carrier bar, a first limiting plate 343 is disposed on the carrier bar on the other side of the notch 342, the first limiting plate 343 is inverted L-shaped, a vertical edge of the first limiting plate 343 is connected to the carrier bar, and a transverse edge of the first limiting plate 343 shields the notch 342.
