Wireless bicycle trip meter
First Claim
1. A trip meter adapted to be used in a bicycle for displaying a plurality of trip data of said bicycle, wherein said bicycle has a signal transmitter for outputting a pulse signal each time said bicycle travels over a specific distance, comprising:
- a bracket secured to a member of said bicycle;
a main body detachably secured to said bracket;
a signal receiving circuit positioned in said main body for wirelessly receiving said pulse signal outputted from said transmitter;
a signal processing circuit electrically connected to said signal receiving circuit for counting a number and a frequency of said pulse signal and correspondingly generating an output signal indicative of said plurality of trip data;
a display circuit electrically connected to said signal processing circuit for displaying said output signal generated from said signal processing circuit;
a battery built in said main body for supplying a power to said signal receiving circuit, said signal processing circuit, and said display circuit; and
a detector positioned in said main body for detecting a connective state of said main body and said bracket so that said signal receiving circuit is unable to wirelessly receive said pulse signal of said transmitter when said main body of said trip meter is detached from said bracket on said bicycle.
