Abstract

A human-powered vehicle driving device includes a motor that assists in propulsion of a human-powered vehicle and a first electric switch including an operation member.

First claim

What is claimed is:

1. A human-powered vehicle driving device comprising:
an inserting portion that allows insertion of a crankshaft of a human-powered vehicle having a front side and a rear side;
a motor that assists in propulsion of the human-powered vehicle via the crankshaft or a front sprocket;
a wireless communication unit;
a first electric switch including an operation member that causes a wireless communication from the wireless communication unit; and
a base including the inserting portion, the motor, the wireless communication unit and the first electric switch, the inserting portion extending through a peripheral portion of the base in a widthwise direction of the human-powered vehicle, the first electric switch located on the peripheral portion of the base in the widthwise direction of the human-powered vehicle so that the operation member of the first electric switch different from the crankshaft is exposed from the base when the base is attached to the human-powered vehicle with the crankshaft inserted into the inserting portion, the wireless communication unit located between the crankshaft and the front side of the human-powered vehicle when the base is attached to the human-powered vehicle with the crankshaft inserted into the inserting portion, the wireless communication unit exposed from the base and removably attachable to the base through engagement of the wireless communication unit with a recess in the base.

2. The human-powered vehicle driving device according to claim 1 , wherein
the first electric switch is configured to output an electric signal for changing a control state of the motor.

3. The human-powered vehicle driving device according to claim 1 , wherein
the first electric switch further includes a positioning member including a first recess configured to receive at least part of the operation member.

4. The human-powered vehicle driving device according to claim 1 , wherein
the base is provided with a reduction gear.

5. The human-powered vehicle driving device according to claim 1 , wherein
the first electric switch is provided on the base, and
at least part of the operation member protrudes outward in the widthwise direction from an outer side of the base.

6. The human-powered vehicle driving device according to claim 1 , wherein
the operation member protrudes outward in the widthwise direction from the peripheral portion of the base.

7. The human-powered vehicle driving device according to claim 1 , wherein
the first electric switch is integrated with the base.

8. The human-powered vehicle driving device according to claim 1 , wherein
the base includes a first mounting portion that mounts the first electric switch.

9. The human-powered vehicle driving device according to claim 1 , wherein
the wireless communication unit is provided on the peripheral portion of the base.

10. The human-powered vehicle driving device according to claim 1 , wherein
the first electric switch is configured to output an electric signal and the wireless communication unit is configured to perform wireless communication in response to the electric signal outputted by the first electric switch.

11. The human-powered vehicle driving device according to claim 1 , wherein
the base includes a second mounting portion that mounts the wireless communication unit.

12. The human-powered vehicle driving device according to claim 1 , further comprising
a first controller electrically connected to the first electric switch and configured to control the motor, and upon operation of the operation member of the first electric switch, an electric signal is outputted from the first electric switch to the first controller to activate the first controller.

13. The human-powered vehicle driving device according to claim 1 , wherein
the operation member causes a change of a control state of the motor and causes the wireless communication from the wireless communication unit.

14. The human-powered vehicle driving device according to claim 1 , wherein
the operation member causes the wireless communication to be sent from the wireless communication unit to a transmission.

15. The human-powered vehicle driving device according to claim 1 , wherein
the wireless communication unit does not overlap the front sprocket when viewed from an axial direction of the crankshaft.
