As Figure 1 shown in, the first reinforcing member 11 is a triangular sheet body, and two of the sides of the triangular sheet body are supported between the vertical section 21 and the head tube 1. The first reinforcing member 11 can increase the contact area between the head tube 1 and the first beam 2, thereby enhancing the support strength of the frame.
[0036] Optionally, the two sides of the first reinforcing member 11 can be respectively connected to the head tube 1 and the vertical section 21.
[0037] One end of the horizontal section 22 away from the vertical section 21 is connected to a seat tube 3. The seat tube 3 is vertically arranged, and the top of the seat tube 3 is used to connect a seat. A second reinforcing member 31 is provided at the connection part between the seat tube 3 and the horizontal section 22. As Figure 2 shown in, the second reinforcing member 31 includes two triangular sheet bodies, and the two triangular sheet bodies are located on the upper and lower sides of the horizontal section 22. The two sides of the triangular sheet body are respectively connected to the seat tube 3 and the horizontal section 22. Both the first reinforcing member 11 and the second reinforcing member 31 can enhance the overall support strength of the frame.
[0038] A second beam is connected to the same side of the seat tube 3 and the cross section 22, and the second beam includes two rods 41 arranged in parallel, and a first connecting member 42 connecting one end of the two rods 41, and the first connecting member 42 is arc-shaped. The first connecting member 42 is located at one end of the rod 41 close to the first beam 2. A first connecting column 411 is provided on the side of the rod 41, and the two ends of the first connecting column 411 are respectively connected to the rod 41 and the seat tube 3. The first connecting member 42 is provided with a second connecting column 421, and the two ends of the second connecting column 421 are respectively connected to the first connecting member 42 and the cross section 22 of the first beam 2.
[0039] The end of the rod 41 of the second beam away from the first connecting member 42 is connected to a rear wheel mounting frame, and the rear wheel mounting frame includes two other support frames 51 arranged in parallel, wherein one of the support frames 51 is connected to the ends of the two rods 41 away from the first connecting member 42. The two support frames 51 are connected by a second connecting member 52. The space between the two support frames 51 is used to mount the rear wheel.
[0040] A power box 6 is provided between the saddle pipe 3, the second beam and the rear wheel mounting frame, and the three sides of the power box 6 are respectively connected to the saddle pipe 3, the second beam and the rear wheel mounting frame. In the present application, a connecting strip 412 is provided on the rod 41 of the second beam, and the two sides of the connecting strip are respectively connected to the rod 41 and the power box 6.
