Abstract

An electronic power control assembly for a bicycle electronic device, a system having the same, and a control method thereof are disclosed. The electronic power control assembly is adapted to be electrically connected to a power source and a control module for controlling at least one electronic device on a bicycle to operate and includes a sensing unit for sensing a motion state of the bicycle, a first timing unit adapted to count a first predetermined time period, and a first control unit. When the sensing unit senses that the bicycle is in a moving state, the first control unit controls the first timing unit to recount and controls the power source to supply electricity to the control module. When the first timing unit finishes counting the first predetermined time period, the first control unit controls the power source to stop supplying electricity to the control module.

First claim

What is claimed is:

1. An electronic power control assembly for a bicycle electronic device, which is adapted to be electrically connected to a power source and a control module, wherein the control module is adapted to control at least one electronic device on a bicycle to operate; the electronic power control assembly comprising:
a sensing unit which is adapted to sense a motion state of the bicycle;
a first timing unit which is adapted to count a first predetermined time period; and
a first control unit, which is electrically connected to the power source, the sensing unit, and the first timing unit, wherein when the sensing unit senses that the bicycle is in a moving state, the first control unit controls the first timing unit to recount and controls the power source to supply electricity to the control module; when the counted first predetermined time period in the first timing unit is completed, the first control unit controls the power source to stop supplying the electricity to the control module.

2. The electronic power control assembly of claim 1 , wherein when the sensing unit senses that the bicycle is changed from a stationary state to the moving state, the first control unit controls the first timing unit to recount and controls the power source to supply electricity to the control module.

3. An electronic power control system, which is adapted to be disposed on a bicycle, comprising:
a power source;
a control module, which is electrically connected to at least one electronic device on the bicycle and is adapted to control the at least one electronic device on the bicycle to operate; and
an electronic power control assembly, comprising:
a sensing unit which is adapted to sense a motion state of the bicycle;
a first timing unit which is adapted to count a first predetermined time period; and
a first control unit, which is electrically connected to the power source, the sensing unit, and the first timing unit, wherein when the sensing unit senses that the bicycle is in a moving state, the first control unit controls the first timing unit to recount and controls the power source to supply electricity to the control module; when the counted first predetermined time period in the first timing unit is completed, the first control unit controls the power source to stop supplying electricity to the control module.

4. The electronic power control system of claim 3 , wherein when the sensing unit senses that the bicycle is changed from a stationary state to the moving state, the first control unit controls the first timing unit to recount and controls the power source to supply electricity to the control module.

5. The electronic power control system of claim 3 , wherein the control module includes a second control unit and a second timing unit, which are electrically connected to each other; the second timing unit is adapted to count a second predetermined time period; when the counted second predetermined time period in the second timing unit is completed, the second control unit controls the at least one electronic device to enter a low voltage mode from a normal mode, wherein the at least one electronic device consumes less power in the low voltage mode than in the normal mode.

6. The electronic power control system of claim 5 , wherein the control module includes a communication unit connected to the second control unit; when the communication unit receives a control signal for controlling the at least one electronic device, the second control unit controls the at least one electronic device to enter the normal mode from the low voltage mode and controls the second timing unit to time the second predetermined time period, and sends a reset signal to the electronic power control assembly, so as to control the first timing unit to recount the first predetermined time period.

7. The electronic power control system of claim 5 , wherein after the second timing unit finishes counting the second predetermined time period, the second timing unit further counts a third predetermined time period; when the second timing unit finishes counting the third predetermined time period, the second control unit controls the at least one electronic device to enter a sleep mode from the low voltage mode, wherein the at least one electronic device consumes less power in the sleep mode than in the low voltage mode.

8. The electronic power control system of claim 7 , wherein a length of the first predetermined time period is greater than a length of the second predetermined time period, and the length of the first predetermined time period is greater than a length of the third predetermined time period.

9. The electronic power control system of claim 8 , wherein the length of the first predetermined time period is greater than a sum of the length of the second predetermined time period and the length of the third predetermined time period.

10. A control method of an electronic power control system as claimed in claim 3 , comprising the steps of:
counting the first predetermined time period by the first timing unit; and
sensing whether the bicycle is in the moving state or not by the sensing unit; if so, the first control unit controls the first timing unit to recount, and controls the power source to supply electricity to the control module; otherwise, determining whether the counted first predetermined time period is completed or not; if the counted first predetermined time period is completed, the first control unit controls the power source to stop supplying electricity to the control module.

11. The method of claim 10 , wherein when the sensing unit senses that the bicycle is in the moving state and the power source supplies electricity to the control module, a second timing unit of the control module counts a second predetermined time period.

12. The method of claim 11 , further comprising a step of determining whether the control module is received a control signal or not; if so, the control module sends a reset signal to the electronic power control assembly, so as to control the first timing unit to recount the first predetermined time period and to control the at least one electronic device in response to the control signal; otherwise, determining whether the counted second predetermined time period is completed or not; once the counted first predetermined time period is completed, the control module controls the at least one electronic device to enter a low voltage mode from a normal mode, wherein the at least one electronic device consumes less power in the low voltage mode than in the normal mode.

13. The method of claim 12 , further comprising a step of further counting a third predetermined time period when the counted second predetermined time period is completed; once the counted third predetermined time period is completed, the control module controls the at least one electronic device to enter a sleep mode from the low voltage mode, wherein the at least one electronic device consumes less power in the sleep mode than in the low voltage mode.
