The front frame 1 includes a head tube 12, side frames 11 symmetrically arranged on the left and right, and a mounting plate 16; one end of the side frame 11 is connected to the head tube 12, and the other end of the side frame 11 is connected to the mounting box 4; the side frame 11 includes a first upper tube 111, a second upper tube 112, and a lower tube 113. The first upper tube 111 is L-shaped, one end of the first upper tube 111 is connected to the head tube 12, and the other end of the first upper tube 111 is connected to the mounting box 4. The second upper tube 112 is located below the first upper tube 111, one end of the second upper tube 112 is connected to the head tube 12, and the other end of the second upper tube 112 is connected to the lower end of the first upper tube 111. One end of the lower tube 113 is connected to the second upper tube 112, and the other end of the lower tube 113 is connected to the mounting box 4. Several reinforcing tubes 114 are provided between the first upper tube 111 and the second upper tube 112; the lower ends of the side frames 11... A front heat sink 13 is provided between the tubes 113, a rear heat sink 14 is provided between the first upper tubes 111 of the two side frames 11, and a crossbeam 15 is provided between the first upper tubes 111 of the two side frames 11. The two side frames 11, the front heat sink, and the rear heat sink form a battery housing space 17. A battery box 7 is provided in the battery housing space 17. The battery box 7 is set at a roughly vertical angle. The bottom of the battery box 7 is fixed on the mounting plate 16. A guide rod is provided in the battery housing space 17. A guide groove is provided on the battery box 7 to cooperate with the guide rod. The guide rod can constrain the battery box 7 and enable the battery box 7 to be accurately positioned.
