[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 4 A frame with a dual-battery structure includes a central axis 1, a connecting seat 15 is rotatably installed on the top of the central axis 1, and a seat 16 is provided on the top of the connecting seat 15.

[0025] A support frame 2 is provided on both sides of the central axis 1. The support frame 2 is a rectangular frame with an opening on one side, and the lower end of the support frame 2 is fixed to the side of the connecting rod 3, and the connecting rod 3 is fixed to the bottom of the central axis 1, forming the rear axle of the frame. A mounting plate 14 is provided on the top of the two support frames 2. A plurality of mounting holes are opened on the mounting plate 14, which can be used to install the bucket of the electric bicycle for placing items; at the same time, it also connects the two support frames 2 to improve the supporting strength of the support frame 2.

[0026] Among them, at least two reinforcing rods 13 are arranged in the support frame 2. The ends of the reinforcing rods 13 are fixed to the support frame 2, and the reinforcing rods 13 are cross-connected with each other, thereby strengthening the overall support strength of the support frame 2.

[0027] like Figure 1 and Figure 2 As shown, a first battery box 4 is provided between the two support frames 2 on the side close to the central axis 1. The first battery box 4 has a built-in battery pack. The bottom of the first battery box 4 is placed on the bottom of the support frame 2, and a crossbeam 5 is provided on the side of the first battery box 4 away from the central axis 1. The end of the crossbeam 5 is fixed to the support frame 2, that is, the first battery box 4 is inserted between the two support frames 2, and the crossbeam 5 and the central axis 1 are used to limit the first battery box 4, which not only ensures the stability of the placement of the first battery box 4, but also facilitates the disassembly of the first battery box 4 therein.

[0028] like Figure 1 and Figure 3 As shown, a support rod 6 is installed in the middle of the other side of the connecting rod 3, and the other end of the support rod 6 is bent upward and connected to the front axle 8, and a limit rod 7 is provided on both sides above the support rod 6, and one end of the limit rod 7 is fixed to the front axle 8, and the other end of the limit rod 7 is fixed to the upper end of the support frame 2, constituting the front axle of the frame. In actual use, the front axle 8 is a sleeve with openings at both ends, and a rotating shaft is rotatably installed in the front axle 8, so that the front wheel and the handle of the electric bicycle can be installed on the rotating shaft to realize the steering control of the electric bicycle.

[0029] Furthermore, the limiting rod 7 is an arc-shaped rod that is tilted and bent at the bottom toward the horizontal direction, so that the frame portion between the front axle 8 and the middle axle 1 is recessed downward to leave sufficient space for the driver to sit on the seat 16 with his legs bent forward.

[0030] like Figure 1 and Figure 4 As shown, a second battery box 9 is provided above the support rod 6. The second battery box 9 has a built-in battery pack. The second battery box 9 is mounted on a fixed seat, and the fixed seat is connected to the support rod 6 through a clamp 11. Two limiting rods 7 are arranged on both sides of the second battery box 9 to limit the two sides of the second battery box 9 so that the second battery box 9 is limited and stabilized after being placed on the fixed seat.

[0031] It should be noted that the fixing seat includes a support plate 10, a clamp 11 is fixed to the bottom of the support plate 10, and the support plate 10 is arranged parallel to the upper end of the support rod 6, and a load-bearing plate 12 is vertically installed at the bottom of the support plate 10, forming an "L"-shaped fixing seat, wherein the second battery box 9 is placed on the inner side of the fixing seat. The "L"-shaped fixing seat can lift the second battery box 9 placed therein, thereby supporting and fixing the second battery box 9, so that the second battery box 9 is stabilized.

[0032] Specifically, battery boxes for installing batteries are respectively provided at the front axle and the rear axle of the frame, so that the electric bicycle using the frame has at most two power supply batteries, thereby improving the endurance of the electric bicycle using the frame and allowing it to have a longer usage time.

[0033] It should be further explained that the support frame 2, the support rod 6 and the limit rod 7 are all hollow metal tubes, which improve the lightweight degree of the frame while ensuring the stress strength of the frame.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
