ANTI-THEFT DEVICE FOR BICYCLES

摘要

An anti-theft device for a bicycle includes a tilt sensor attached to the bicycle wherein the tilt sensor has a tilt switch to detect upright orientation of the bicycle; a microcontroller, electrically connected to the tilt sensor; a transceiver, electrically connected to the microcontroller, which wirelessly transmits or receives signals; a computing device to wirelessly receive or transmit the signals; and a software application installed on the mobile computing device. If the tilt sensor detects an upright orientation of the bicycle, it sends a signal for the upright orientation to the microcontroller and the signal is forwarded to the software application. Then, the software application sends a warning to a user through a user interface. If the tilt sensor detects an upright orientation of the bicycle, it sends a signal for the upright orientation to the microcontroller and the microcontroller activates a warning beep to emit a high-pitched sound.

1. An anti-theft device for a bicycle, comprising:
a tilt sensor attached to the bicycle wherein the tilt sensor has a tilt switch to detect upright orientation of the bicycle; a microcontroller, electrically connected to the tilt sensor; a transceiver, electrically connected to the microcontroller, which wirelessly transmits or receives signals a computing device to wirelessly receive or transmit the signals; a software application installed on the computing device, and a housing to house the tilt sensor, the microcontroller and the transceiver, wherein the housing is mounted on the bicycle by a clamp,wherein if the tilt sensor detects an upright orientation of the bicycle, the tilt, sensor sends a signal for the upright orientation to the microcontroller which is then transmitted to the transceiver, to the computing device and then to the software application,wherein the tilt sensor sends signals of an orientation of the bicycle at predetermined intervals to the microcontroller,wherein if the tilt sensor sends signals of the upright orientation of the bicycle for a predetermined time, the software application sends a warning to a user through a use interface and the microcontroller activates a warning beep to emit a high-pitched sound,wherein the clamp is clamped to a seat post of the bicycle,wherein the housing is connected to the clamp by a hinge joint so that an angle of the housing can be adjusted with respect to the bicycle to align the tilt switch to the upright orientation of the bicycle in order for the tilt switch to detect the upright orientation of the bicycle,wherein the hinge joint is substantially perpendicular to a plane of the bicycle.
