The invention relates to a bicycle foot stand capable of being automatically opened; the stand comprises a transmission mechanism arranged in a shell, the shell is fixed to a bicycle frame mechanism, power of pedals can be transmitted to the foot stand through the transmission mechanism, and the foot stand is driven to be opened. The transmission mechanism comprises a connecting shaft rotationally connected into the shell, the connecting shaft is connected with the shell through two torsional springs, a driven gear is fixedly arranged on the connecting shaft, and a gear strip is arranged in the shell in a sliding mode. According to the invention, the foot stool can be opened through rotation of the pedal plate; a phenomenon that the rider is in danger due to fact that foot stand is not opened when riding bicycle is avoided. A driving gear is arranged on a pedal shaft, when a pedal rotates, the driving gear is driven to rotate through the pedal shaft, the foot stool is driven to rotate through transmission of a rack and a driven gear, and after the rack is completely disengaged from the driving gear, the foot stool is completely opened through the elastic force of the torsion spring.

    本发明的一种自动打开的自行车脚架,包括传动机构,所述传动机构设置在外壳内,所述外壳固定在车架机构上,通过所述传动机构可以将脚踏板的动力传递到脚架上,并带动所述脚架打开,所述传动机构包括转动连接在所述外壳内的连接轴,且所述连接轴与所述外壳之间通过两个扭簧连接,所述连接轴上固定设有从动齿轮,所述外壳内滑动设有齿轮条,本发明可以通过脚踏板的转动将脚架打开,避免骑行者在骑自行车时脚架未打开,而发生危险,本发明在脚踏板轴上设有主动齿轮,当脚踏板转动时通过脚踏板轴带动主动齿轮转动,通过齿条与从动齿轮的传动带动脚架转动,待齿轮条与主动齿轮完全脱离啮合后,通过扭簧的弹力将脚架完全打开。
