RADIO FREQUENCY IDENTIFICATION SYSTEM SELF-ADAPTIVE TO CHANGE IN BICYCLE WHEEL SIZE

摘要

Disclosed in the present invention is a radio frequency identification system self-adaptive to a change in the bicycle wheel size, comprising a radio frequency tag and a radio frequency identification module provided on a lock stand; the radio frequency tag is provided on an axle of a bicycle wheel, and the lock stand comprises a locking rocker, the lower end portion of the locking rocker being rotatably connected to the lock stand, the upper end portion of the locking rocker being locked to the front end of the bicycle wheel; the radio frequency identification module is provided on the locking rocker, with the center of the radio frequency identification module being located above the rear portion of the rotation center of the locking rocker. In the present invention, the radio frequency tag and the radio frequency identification module in the radio frequency identification system can complete self-adaptation. When the size of the bicycle wheel locked by the lock stand gradually increases, the position of the radio frequency tag gradually rises, the swing amplitude of the locking rocker gradually increases, and the center of the radio frequency identification module also gradually rises. Locking of bicycle wheels of different sizes corresponds to different swing amplitudes of the locking rocker, realizing the adaptive adjustment of the adaptation distance in the space between the radio frequency tag and the radio frequency identification module.
