The controller is coupled to the battery cell and the center motor for controlling the rotation of the motor.

According to an embodiment of the invention, the center motor is located on the rear side of the battery cell.

According to an embodiment of the invention, the bicycle five-way is uniformly provided with a plurality of air guiding grooves at the periphery of the center motor.

According to an embodiment of the present invention, one of the two side surfaces of the center motor perpendicular to the axial direction of the motor protrudes from the surface of the battery on the same side.

According to an embodiment of the invention, the battery cells are disposed in two spaced apart cavities of the bicycle five-way.

According to an embodiment of the invention, a waterproof material is disposed between the bicycle five-way and the battery core.

According to an embodiment of the invention, a GPS module is further disposed in the bicycle five-way.

According to one embodiment of the invention, the riser of the bicycle is also equipped with an external battery.

The invention has the advantages that the electric bicycle integrated with the battery and the motor of the invention has the battery and the motor disposed in the bicycle five-way, shortens the connection circuit and reduces the energy loss; sets the air guiding groove, and improves the battery by using the air pressure difference The heat dissipation effect; the center of the entire bicycle is lower, which improves the safety of the bicycle.

detailed description

1 shows a schematic view of a drive mechanism of an embodiment of the present invention. The drive mechanism includes a bicycle five-way 100 and a center motor 200 located in a cavity of the bicycle five-way 100, a plurality of battery cells 300, and a controller 400. The power converter 500 and the power protection board 600 may further include: the battery cell 300 and the center motor 200 are separated by a five-way cover 120 and connected by a circuit; the controller 400 controls the motor and the electric vehicle. For other components, the power converter 500 converts the voltage of the battery to a low voltage available to other components. As shown in FIG. 1, a plurality of battery cells 300 may be disposed in a plurality of chambers of the bicycle five-way 100, and the plurality of chambers are separated by a five-way cover 120 to prevent the battery cells 300 from generating excessive heat. It cannot be dissipated in time. As shown in FIG. 2, a waterproof material 800 may be disposed between the battery cell 300 and the bicycle five-way 100 to prevent the battery pack from entering the water and causing a safety accident.

In another embodiment of the present invention, as shown in FIG. 2, the center motor 200 is located at the rear side of the battery cell 300, so that the center motor 200 is closer to the rear wheel, shortening the connection of the center motor 200 and the rear wheel. The length of the chain between the axles. In this embodiment, the bicycle five-way 100 is uniformly provided with a plurality of air guiding grooves 110 at a position outside the center motor 200. As shown in FIGS. 3-5, one of the two side surfaces of the center motor 200 perpendicular to the axial direction of the motor protrudes from the surface of the battery on the same side. Thus, when the electric bicycle advances, due to the blocking effect of the protruding portion of the center motor on the air, the air pressure outside the air guiding groove 110 near one end of the battery cell 300 is higher than the atmospheric pressure, and is away from the outside of the air guiding groove 110 at one end of the battery cell 300. The gas pressure is lower than the atmospheric pressure, and the gas pressure on the non-projecting side of the center motor 200 is substantially the same as the atmospheric pressure. Therefore, at the end close to the battery cell 300, the gas flows from the side where the center motor 200 protrudes to the non-bumping. On one side; at the end remote from the battery cell 300, the gas flows from the unprojected side of the center motor 200 to the convex side, and the battery cell 300 and the center motor are taken away during the gas flow. The heat generated by 200 avoids excessive heat and reduces the safety and life of the component.

In a preferred embodiment of the present invention, as shown in FIG. 1, a bicycle module 700 is further disposed in the bicycle five-way for providing navigation services for the electric bicycle.

In a preferred embodiment of the present invention, as shown in FIG. 6, in the case where long-time riding is required, an extra battery can be provided on the riser of the electric bicycle integrated with the battery and the motor of the present invention, thereby Provide longer endurance.

While the embodiments of the present invention have been described in detail, various alternative designs and embodiments defined by the claims, which are <RTIgt;
