Abstract

The present disclosure provides a clamping device including a clamping device body, and a control module connected to the clamping device body, wherein the control module is configured to acquire cycling information and control locking and unlocking of the clamping device body based on the cycling information.

First claim

What is claimed is:

1. A clamping device, comprising:
a clamping device body; and
a control module connected to the clamping device body, wherein the control module is configured to acquire cycling information and control locking and unlocking of the clamping device body based on the cycling information,
wherein the control module comprises an acquisition module and a clamping device control module, the acquisition module is configured to acquire a pedaling frequency and an acceleration,
the control module is configured to determine a cycling state based on the pedaling frequency and the acceleration, the cycling state comprises an original state, a riding state and a braking state, and the control module is further configured to: keep the clamping device body in a first position in the event that the cycling state is the original state; rotate the clamping device body to a second position and keep the rotated clamping device in the second position to lock the clamping device in the event that the cycling state is the riding state; and rotate the clamping device body to the first position to unlock the clamping device in the event that the cycling state is the braking state.

2. The clamping device according to claim 1 , wherein the clamping device body comprises an upper clamping member and a lower clamping member configured to secure the locking sheet therebetween.

3. The clamping device according to claim 2 , wherein
in the first position, a symmetry axis for the upper and lower clamping members is at a first angle to a symmetry axis of the locking sheet to enable the locking sheet to slip out of the clamping device body, and
in the second position, the symmetry axis of the upper and lower clamping members is at a second angle to the symmetry axis of the locking sheet to fix the locking sheet in the clamping device body.

4. A pedal, comprising the clamping device according to claim 1 .

5. A bicycle, comprising the pedal according to claim 4 .

6. A method of controlling a clamping device, comprising:
acquiring cycling information; and
controlling locking and unlocking of a clamping device body based on a pedaling frequency and an acceleration,
determining a cycling state based on the pedaling frequency and the acceleration, wherein the cycling state comprises an original state, a riding state and a braking state; and
keeping the clamping device body in a first position, in the event that the cycling state is the original state; rotating the clamping device body to a second position and keeping the clamping device body in the second position to lock the clamping device, in the event that the cycling state is the riding state; and rotating the clamping device body to the first position to unlock the clamping device, in the event that the cycling state is the braking state.

7. The method according to claim 6 , wherein the determining the cycling state based on the pedaling frequency and the acceleration comprises:
determining the cycling state to be the original state in the event that the pedaling frequency is zero and the acceleration is zero;
determining the cycling stat to be the riding state in the event that the pedaling frequency is not zero and the acceleration is positive or in the event that the pedaling frequency is not zero and the acceleration is zero; and
determining the cycling state to be the braking state in the event that the pedaling frequency is not zero and the acceleration is negative or in the event that the pedaling frequency is zero and the acceleration is negative.

8. The method according to claim 6 , wherein
the cycling state further comprises a climbing state,
the determining the cycling state based on the pedaling frequency and the acceleration comprises:
detecting whether a user performs a braking operation, in the event that the pedaling frequency is not zero and the acceleration is negative or in the event that the pedaling frequency is zero and the acceleration is negative;
determining the cycling state to be the climbing state and keeping the clamping device body in the second position, in response to detecting that the user does not perform the braking operation; and
determining the cycling state to be the braking state and rotating the clamping device body to the first position to unlock the clamping device, in response to detecting that the user performs the braking operation.
