Bicycle generator and motor combo system

Abstract

This invention discloses a bicycle generator and motor integrated system, comprising: a housing having an accommodating space; at least one stator assembly disposed within the accommodating space; a rotor assembly disposed within the accommodating space and adjacent to the at least one stator assembly; and a control component partially passing through the accommodating space, the rotor assembly, and the at least one stator assembly, and having a screw having at least one positive thread segment and at least one negative thread segment, wherein the at least one stator assembly is screwed to either the positive thread segment or the negative thread segment; wherein, by operating the control component, the screw is rotated, and the positive thread segment or the negative thread segment drives the stator assembly to move axially along the screw, thereby changing the distance between the at least one stator assembly and the rotor assembly.

2. The bicycle generator and motor combo system as described in claim 1, wherein, The at least stator group further includes a first base and a plurality of coils, each coil being disposed on the first base and on one side of the at least stator group opposite to the rotor group, and the coils being arranged in a ring-shaped arrangement with spacing.

3. The bicycle generator and motor combo system as described in claim 1, wherein, The rotor assembly further includes at least one second base and a plurality of magnets, each magnet being disposed on the at least one second base and arranged in a ring at intervals.

4. The bicycle generator and motor combo system as described in claim 1, wherein, When the number of stator groups is four, the rotor group further includes two second seats, each second seat being disposed between the corresponding two stator groups. The screw further includes two positive thread sections and two negative thread sections, and the two positive thread sections and the two negative thread sections are arranged alternately in sequence. The four stator groups are respectively screwed to the corresponding positive thread sections or negative thread sections, and generate axial displacement as the screw rotates, so as to adjust the distance between each stator group and the corresponding second seat.

5. The bicycle generator and motor combo system as described in claim 1, wherein, The control assembly further includes a slide rail assembly having a first slide rail member and a second slide rail member. The first slide rail member extends into the receiving space from one end face of the housing and passes through the rotor assembly and the at least one stator assembly. The second slide rail member is located on the other end face of the housing. The first slide rail member has a plurality of gaps. The screw passes through the slide rail assembly, and the at least one positive thread segment and the at least one negative thread segment correspond to the positions of each gap. The slide rail assembly is used to restrict the radial rotation of the at least one stator assembly and allow the at least one stator assembly to be axially displaced according to a predetermined trajectory.

6. The bicycle generator and motor combo system as described in claim 5, wherein, The at least one sub-assembly further has a locking portion that passes through each gap and is screwed into the corresponding positive or negative thread segment.

7. The bicycle generator and motor combo system as described in claim 1, wherein, The control assembly further includes a shaft and a fixing assembly. The shaft passes through the screw and both ends of the shaft are exposed outside the housing. The fixing assembly is attached to both ends of the shaft to fix the shaft.

8. The bicycle generator and motor combo system as described in claim 1, wherein, The control component further includes an adjustment handle, which is configured with the screw. The rotation of the adjustment handle drives the screw to rotate synchronously, and indirectly adjusts the distance between the rotor assembly and the at least one stator assembly.

9. The bicycle generator and motor combined system as described in claim 1, wherein, The control component further includes a control terminal and a controller. The control terminal is electrically connected to the controller. The control terminal drives the screw to rotate by electrically controlling the controller, thereby adjusting the distance between the rotor assembly and the at least one sub-assembly.

10. The bicycle generator and motor combo system as described in claim 1, wherein, The control component can control the distance between the at least certain subgroup and the rotor group so that the system can generate electricity.

11. The bicycle generator and motor combined system as described in claim 1, wherein, The control component can control the distance between the at least certain subgroup and the rotor group so that the system can perform motor-driven operation.

12. The bicycle generator and motor combo system as described in claim 1, wherein, The control component can control the distance between the at least certain subgroup and the rotor group to adjust the magnetic reluctance of the system.

13. The bicycle generator and motor combined system as described in claim 1, wherein, This shell system can be installed on the hub or the center of the chainring of a bicycle.

14. The bicycle generator and motor combo system as described in claim 9, wherein, The control terminal can be a bicycle watch, or a personal mobility or smart wearable device, for wired or wireless control.
