Further, the reinforcing pipe 3 is obliquely arranged, and the reinforcing pipe 3, the vehicle beam 1 and the middle pipe 2 form a stable triangular structure, so that the overall strength of the vehicle frame is improved.

A five-way pipe 8 is fixedly arranged on the front side of the middle pipe and is connected with the lower end part of the reinforcing pipe.

As shown in fig. 4, the bottom of the reinforced pipe 3 has an inner curved surface 32, the end of the curved surface is lower than the lower side surface of the five-way pipe, and the curved surface and the outer side surface of the five-way pipe form the notch 31. The design of the inner curved cambered surface can avoid scraping and collision possibly caused by sharp corners while keeping the formation of the notch to facilitate wiring.

The battery spring wire 6 has a spring ring 61 in the middle, which is received in the reinforcing tube. The provision of the spring coils enables the battery spring wire as a whole to obtain the necessary amount of expansion and contraction when both ends of the battery spring wire 6 are stretched.

Furthermore, the window 11 and the cover plate 12 are disposed on the lower side of the vehicle beam 1, which is convenient for disassembly and does not cause visual obstruction and scraping. The cover plate 12 can be fixed on the surface of the vehicle beam by screws at the periphery, and tools are used when disassembly is needed. The inboard of apron 12 is provided with the joint position, and the controller is fixed to be provided with the pothook, pothook and joint position accordant connection to guarantee that the controller is fixed in the apron, keep certain stability in riding. Meanwhile, when the cover plate 12 is opened during disassembly, the controller can be taken out after the cover plate is pulled open, and then the clamping hook and the clamping position are manually separated, so that the cover plate and the controller can be completely stripped, and the disassembly is very convenient.

The end of the battery spring wire has a plug 62 and the lower end of the seat tube has a port 42 which is connected to the battery pack, the plug and port being matingly connected.
