[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a battery compartment structure for an electric vehicle, including a frame 1, the frame 1 including an L-shaped base frame 13, a middle beam 12 connected to the upper end of the base frame 13, a top frame 11 fixed to the upper end of the middle beam 12 by a connecting rod, a seat mounting seat 2 fastened to the top frame 11, the seat mounting seat 2 being fixed to a connecting piece on the inner side of the top frame 11 by bolts, the seat mounting seat 2 having an insertion hole 24, the insertion hole 24 being a rectangular hole for inserting a battery, the insertion hole 24 having downward guide walls 25 formed at the four corners of the insertion hole 24, the guide walls 25 limiting the side of the battery to prevent the upper end of the battery from moving left and right, the battery is positioned by the seat mounting seat 2, compared with the existing seat bucket battery compartment, the use of plastic material is greatly reduced, meeting the requirements of the new national standard.

[0023] like Figure 3 and 4 As shown, the lower end of the frame 1 is connected to the bottom beam 14, and the top frame 11 and the bottom beam 14 are connected to the support column 3.
