Description

Technical Field

[0001] The utility model relates to the field of electric power-assisted bicycles, in particular to a connection structure of a motor connection line and a controller connection line of an electric power-assisted bicycle. Background Art

[0002] Electric-assisted bicycles are different from ordinary bicycles in that they use electric motors as an auxiliary power output source to provide power assistance when the rider is riding. This is also different from ordinary electric bicycles. Electric bicycles use motors as the complete power output source, and when the power is insufficient, they use pedals as an alternative power source. The motor of an electric-assisted bicycle is mainly used as auxiliary power when riding. Therefore, electric-assisted bicycles are more like an upgrade of traditional bicycles.

[0003] For electric-assisted bicycles with rear-wheel hub motors, how to effectively connect the motor's electrical connection wires to the frame and controller while ensuring a stable and convenient connection has become an urgent problem to be solved. The traditional connection method is to insert the motor connection wires from the frame, pass through the entire frame rear fork, and then connect to the controller set near the frame downtube or the five-way. Although this meets the connection requirements to a certain extent, the distance the motor connection wires pass through the pipe from the inside is quite long, and the connection position between the motor connection wires and the controller is not convenient to operate. Disassembly during maintenance, replacement of motors, or replacement of tires will be very cumbersome. This traditional connection method requires the rider to first separate the connection wires of the rear hub motor from the controller and then completely pull them out of the frame. Not only is the operation complicated, but it is also time-consuming and labor-intensive, greatly reducing the convenience of the user experience.

[0004] Therefore, a solution is needed to enable the electrical connection line of the rear hub motor of the electric power-assisted bicycle to be connected to the controller conveniently and quickly. Utility Model Content

[0042] Please refer to Figures 1 - 5, the present utility model mainly provides a wire connection structure for an electric assist bicycle, including a first connector 1, a second connector 2 and a fixed connection plate 3. The fixed connection plate 3 may be provided with a fixing hole 31, a connection hole 32 and a first magnetic member 33. The fixed connection plate 3 can be fixed to the wire outlet opening of the rear fork of the electric assist bicycle through the fixing hole 31 and a fixing member. The fixed connection plate 3 includes an inner side 34 and an outer side 35; the first connector 1 includes a first connection portion 11, and the first connection portion 11 is matched with the connection hole 32 and is connected to the connection hole 32 by the inner side 34; the second connector 2 includes a second connection portion 21 and a second magnetic member 22. The second connection portion 21 is inserted into the connection hole 32 from the outer side 35 and is electrically connected to the first connection portion 11. More specifically, a plurality of connection terminals 12 are provided inside the first connection portion 11, and a plurality of terminal jacks 23 are provided on the second connection portion 21. The plurality of connection terminals 12 and the plurality of terminal jacks 23 are arranged correspondingly. After the first connection portion 11 and the second connection portion 21 are inserted and connected through the connection hole 32, the power and signal transmission between the controller and the rear wheel motor module are completed thereby.

[0043] The second magnetic member 22 and the first magnetic member 33 are arranged correspondingly, and the second magnetic member and the first magnetic member attract each other. In this embodiment, both the first magnetic member 33 and the second magnetic member 22 may be magnets, or one of them may be a magnet and the other may be an element made of a magnetizable material.

[0044] Furthermore, in this embodiment, the frame of the electric assist bicycle is a hollow structure. Therefore, when the fixed connection plate 3 is fixed to the wire outlet hole of the rear fork of the electric assist bicycle, the inner side 34 of the fixed connection plate 3 is located inside the rear fork tube of the frame of the electric assist bicycle, and the outer side 35 of the fixed connection 3 is located outside the rear fork tube of the frame of the electric assist bicycle. At the same time, in this embodiment, the first magnetic member 33 is arranged on the outer side 35 of the fixed connection plate 3 for facilitating connection with the second magnetic member 22. However, in another embodiment, a notch may also be opened on the inner side 34 of the fixed connection plate 3, and the first magnetic member 33 may be buried in the notch, so as to avoid the problem that the first magnetic member 33 is rusted due to long-term exposure to the outside. It should be particularly noted that, in this embodiment, the second magnetic member 22 is arranged at the end of the second connector 2. Specifically, one end of the second connector 2 is connected to the motor connecting wire, and the second magnetic member 22 is arranged at the end of the second connector 2 away from the motor connecting wire. Thereby, when the user wants to remove the second connector, only a force perpendicular to the direction of the second magnetic member 2 can be applied to the second connector 2 to better remove the second connector 2. When the force in the direction parallel to the second magnetic member 2 in the force applied by the user is relatively large, due to the influence of the structure of the second connection portion 21 and the magnetic attraction force, the second connector 2 cannot be easily removed, which also ensures the stability of the connection between the second connector 2 and the first connector 1.

[0045] Furthermore, in this embodiment, the first connector 1 is buried inside the rear fork of the electric assist bicycle. Since the frame of the electric assist bicycle is a hollow structure, the first connector 1 and the controller connection wire connected to the first connector 1 are buried inside the frame and connected to the controller of the electric assist bicycle through internal wiring of the hollow frame. The second connector 2 is connected to the rear wheel motor module through a motor connection wire, is arranged outside the rear fork of the electric assist bicycle, and is then connected to the first connector 1 through a fixed connection plate 3. In addition, the first connector 1 and the fixed connection plate 3 can be of a separable or integral structure.

[0046] Since the second connector 2 is arranged outside the frame, in order to avoid problems such as water ingress, a sealing ring 24 is arranged around the first connection part 11 of the first connector 1 and the second connection part 21 of the second connector 2.

[0047] Through the above description, the beneficial effects of the present utility model are as follows:

[0048] 1. Through the fixed connection plate arranged on the wire outlet hole of the rear fork of the electric assist bicycle, the first connector buried inside the frame of the electric assist bicycle and connected to the controller, and the second connector connected to the motor are electrically connected. When the rear wheel with a motor needs to be repaired or modified, only the second connector needs to be removed from the fixed connection plate to complete the separation, greatly improving the convenience of disassembly and modification and repair.

[0049] 2. A first magnetic member is arranged on the fixed connection plate, and a second magnetic member is arranged on the second connector. When the second connector is plugged into the first connector, the first magnetic member and the second magnetic member can prevent the second connector from falling off due to vehicle vibration during riding, improving the connection stability of the second connector.

[0050] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
