[0002] Bicycles, also known as bicycles or bikes, are usually two-wheeled small land vehicles. People ride on the bicycles and use pedals as power. It is a green and environmentally friendly means of transportation. There are many types of bicycles, including single-person bicycles, double-person bicycles, and multi-person bicycles.

[0003] With the progress of the times, traditional pedal bicycles are gradually replaced by power-assisted bicycles. Battery packs are installed on bicycles as auxiliary energy sources, so that when the pedals are stepped on, the battery motor is mobilized to output power to assist riding, thereby playing a power-assisting role. However, most power-assisted bicycle battery packs are now installed on the outside of the bicycle seat tube, which is very unsightly and can be easily discovered by criminals and stolen, resulting in economic losses.

DETAILED DESCRIPTION

[0018] 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 of the embodiments.

[0019] Reference Figure 1-5A bicycle seat tube structure comprises a frame tube 1, a fixed cavity 12 is opened in the frame tube 1, a tube lower cover 5 is installed at the bottom of the frame tube 1, a controller 4 is arranged on the upper surface of the tube lower cover 5, a DC socket 9 is arranged on the controller 4, a battery tube 3 is vertically arranged above the controller 4 and located in the fixed cavity 12, a seat sleeve 2 is movably inserted on the upper end tube body of the battery tube 3, and the seat sleeve 2 is movably arranged in the gap between the fixed cavity 12 and the outer wall of the upper end tube body of the battery tube 3.

[0020] Among them, a plurality of fixing holes 11 are evenly opened on the tube wall of the bottom tube body of the frame tube 1, and an opening 13 is opened on the tube wall of one side of the bottom tube body of the frame tube 1. The size of the opening 13 is consistent with the size of the DC socket 9, and the opening 13 is convenient for the external connection line to connect the internal DC socket 9

[0021] In addition, the tube body with a smaller diameter at the upper part of the battery tube 3 is set as an upper tube body 31, and the tube body with a larger diameter at the lower part of the battery tube 3 is set as a lower tube body 32. A seat sleeve 2 is vertically inserted on the outer wall of the upper tube body 31 and can move up and down. The lower tube body 32 has a larger diameter in order to limit the downward movement distance of the upper seat sleeve 2.

[0022] Moreover, the tube body with a smaller diameter at the top of the seat sleeve 2 is set as a fixed part 21, and the cavity inside the tube body with a larger diameter at the bottom of the seat sleeve 2 is set as a movable part 22. The movable part 22 of the tube body of the seat sleeve 2 is sleeved on the outer wall of the upper tube body 31 and can move up and down, and a conical part 23 is provided between the movable part 22 and the fixed part 21. The conical part 23 can effectively limit the downward movement depth of the seat sleeve 2.

[0023] At the same time, the upper tube body 31 is connected to the lower tube body and has a cavity therein. An upper battery pack 6 is vertically arranged in the cavity of the upper tube body 31, and a lower battery pack 7 is vertically arranged in the cavity of the lower tube body 32. A battery bottom end cover 8 is horizontally installed at the bottom end of the lower tube body 32. The cavity between the upper tube body 31 and the lower tube body 32 can accommodate multiple battery packs, thereby facilitating hiding the battery packs, making the seat tube structure integrated and more beautiful.

[0024] In the present embodiment, after the upper battery pack 6 in the upper tube body 31 and the lower battery pack 7 in the lower tube body 32 are installed and connected, the battery bottom end cover 8 can be installed. After the operator adjusts and connects the controller 4, the frame tube 1 can be sleeved on the battery tube 3, and at the same time, the fixing component is installed into the fixing hole 11 and fixedly connected with the tube lower cover 5, and the seat sleeve 2 can be sleeved on the battery tube 3. After installation on the bicycle, wiring is performed through the DC socket 9, and then a seat harness can be added at the connection between the seat sleeve 2 and the battery tube 3. When adjusting the height of the seat sleeve 2, the operator only needs to pull the seat sleeve 2 up and down, and the seat sleeve 2 moves up and down on the upper tube body 31, and then the purpose of adjusting the seat height can be achieved. Such a design is more convenient.

[0025] In the utility model, the upper battery pack 6 and the lower battery pack 7 are arranged in the battery tube 3, so that the battery pack can be hidden in the bicycle seat tube, and there is no need to install it on the outside, so that the overall structure is integrated, more beautiful and will not be discovered and stolen by criminals, and the seat sleeve 2 arranged on the battery tube 3 is sleeved on the upper tube body 31 and moves up and down, so as to achieve the purpose of adjusting the seat height. In this way, the battery pack can be stored while ensuring that the seat can still be adjusted, so that the functions of the bicycle seat tube are diversified.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
