Electronic brake assembly for a bicycle

摘要

An electronic brake device for use with a wheel of a bicycle provides, among other features, wireless, remote disengagement of a wheel brake. A brake coupled to a housing is movable between an engaged position and a disengaged position. The housing includes a receiver configured to receive a command signal, and a processor operative to identify the received command signal. If the command signal is identified as a first command signal, the processor outputs a first control signal. An electric motor is operatively coupled to the brake to selectively move the brake from the engaged position in which the wheel of the bicycle is being braked to the disengaged position in which the wheel of the bicycle is free of any brake contact in response to the first control signal. Measured movement of the brakes between fully braked or fully disengaged positions are possible in the disclosed arrangement.

主权项

1. An electronic brake device for use with a wheel of a bicycle, comprising:
a housing; a first brake caliper having a first end and a second end that contains a brake pad; a second brake caliper having a first end and second end that contains a brake pad, the first and second brake calipers being pivotally coupled to one another about a main pivot that is a fixed pivot; an electric motor disposed within the housing and being mounted to the first brake caliper; a first gear driven by the electric motor; a gear mechanism that is intimately coupled to the first gear and includes a plurality of gears that are driven by operation of the motor; a pivot arm assembly that is coupled to the main pivot and to a secondary pivot that is operatively coupled to the gear mechanism such that operation of the gear mechanism causes the secondary pivot to move, the pivot arm assembly having a biasing mechanism which applies a force to at least one component of the pivot arm assembly to cause movement thereof, the movement of the at least one component being translated into movement of the calipers between a brake on position in which the brake pads are in contact with the tire to prevent movement thereof and a brake off position in which the brake pads are spaced from the tire to allow movement thereof, wherein the at least one component comprises a pivot arm that pivots about the secondary pivot and the biasing mechanism includes a spring that is attached at one end to the pivot arm and at an opposite end to a first spring arm that is pivotally attached at a first end to the secondary pivot and is pivotally attached at a second end to the fixed main pivot; and a circuit that is configured to receive a remote command signal and activate the electric motor.
