Air pressure control system

摘要

A system for controlling bicycle tire air pressure on the go is provided. The system has a wheel mounted portion and a control unit in communication with one another. The wheel mounted portion attached to each wheel has a gas source, manifold, regulator to control air flow into and out of the tire, and a communication device. The control unit monitors air pressure in each tire, and has a user interface allowing input of a higher or lower tire pressure. Based on user input, the control unit instructs operation of the wheel mounted portion, controlling pressure within the tire.

主权项

1. A system for controlling a tire pressure comprising:
a control unit; and a first and second wheel mounted portion, each wheel mounted portion comprising:
a manifold attached to a hub of a wheel;a compressed gas source, wherein the gas source is a compressed gas canister, having an outlet connected to the manifold, the compressed gas canister connected to the wheel by the manifold;an air line extending from the manifold in fluid communication with the compressed gas source through the manifold, the air line attachable to a stem of the wheel;a pressure sensor in communication with the air line configured to measure a pressure within the tire;a regulator configured to allow gas to exit the stem of the tire, and configured to allow gas from the compressed gas source to flow into the tire; anda transceiver configured to send a data from the pressure sensor relating to the pressure within the tire, and configured to receive a signal instructing the regulator action; wherein the control unit comprises:
a second transceiver in communication with the transceiver of each of the first and second wheel mounted portions; anda user interface in communication with the microprocessor allowing an input instructing an increase in tire pressure and an input instructing a decrease in tire pressure;a microprocessor in communication with the transceiver of the control unit programmed and configured to communicate operating signals through the transceiver to the regulator of each wheel mounted portion to either decrease pressure in the tire by releasing gas in the tire through the stem, or increase pressure in the tire by allowing gas from the gas source into the stem in response to input from the user interface.
