[0022] Example:

[0023] See also Figure 1-5 This embodiment shows an integrated structure of a down tube opening of an electric-assisted bicycle, including a down tube 100 of an electric-assisted bicycle, and a down tube opening 1 is provided on the down tube 100 of the electric-assisted bicycle;

[0024] The DC module 2 is fixedly loaded to the lower tube opening 1, and the DC module 2 includes a lower cover plate 21 for fixedly connecting to the lower tube opening, and a DC module loading bin 22 is connected below the lower cover plate 21;

[0025] The lower cover plate 21 is used as a fastening connection part of the lower tube opening, forming a connection structure to prevent the lower tube opening 1 from reducing the strength of the lower tube;

[0026] The DC module loading compartment 22 is provided with a line connection interface, and the DC module loading compartment 22 and the corresponding inner wall of the lower tube have a line passing space, forming an integrated structure of the lower tube opening of the electric power-assisted bicycle with flexible DC module accommodation and reasonable and standardized line configuration.

[0027] A sealing ring is provided at the connection between the lower cover plate 21 and the lower tube opening 1 .

[0028] A charging docking module 3 is also provided on the lower cover plate 21 .

[0029] The charging docking module 3 includes a Type-A port 31 and a Type-C port 32 .

[0030] The lower cover plate 21 is provided with a sealing cover buckle groove 4, to which a sealing end cover 41 is connected by buckle connection.

[0031] The lower tube opening 1 is in a square shape, with a connecting edge 11 arranged around the circumference, and the four corners of the connecting edge 11 are provided with fixing threaded openings 12 for fastening the DC module.

[0032] The connecting edge 11 on one side of the lower tube opening 1 has a loading and leaving opening.

[0033] The integrated design of the down tube opening of the electric-assisted bicycle in this embodiment cleverly utilizes the down tube space. With the help of the down tube opening, relevant accessories are reasonably placed in the area between the battery and the motor, and the space inside the frame is cleverly utilized. In addition, the down tube cover is fixed with screws on the upper part to create a sealed space inside the down tube space, which can well accommodate the DC module.

[0034] Space is also reserved under the DC module for placing related lines passing through it, so the size design of the DC module has more room for adjustment; at the same time, part of the DC module is suspended in the air, which also makes the related shape of the DC module very flexible.

[0035] The integrated design of the downtube opening of the electric-assisted bicycle can also allow for the storage of some small items in the downtube opening area, assist in the connection of some lines inside the frame, and assist in the installation of the battery. Relevant spaces are opened on the downtube cover to place current input and output devices, supporting Type-A and Type-C ports for charging mobile phones, tablets, laptops and other electronic products. A sealing cover and a sealing ring are set here to ensure functions such as waterproof and dustproof while opening the hole. While meeting user needs, it can ensure product quality is not affected by relevant external factors. It truly realizes multi-function integration, improves the cost-effectiveness of the opening, stabilizes product quality, and promotes diversified iteration and comprehensive development of products.

[0036] The integrated design of the downtube opening of the electric-assisted bicycle also focuses on the improvement of the circuit. For electric-assisted bicycles, the downtube and the five-way joint contain many circuits. The circuits with various functions such as the transfer power supply, charging and discharging ends, input and output are complicated, especially during the setting and installation, which consumes a lot of space and time, and costs a lot of manpower and energy, increases the production burden, and reduces work efficiency. Therefore, the function of the downtube cover is improved here, and an integrated design is realized. The circuit is taken out from the opening, and after the external installation is completed, it is fixed with a sealing ring and screws. The integrated circuit is integrated in this area, which not only improves the product function, but also reduces labor costs, reduces the burden on the production line, and realizes the combination of humanized design and sustainable design.

[0037] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
