The invention discloses an electronic lock self-powered device installed in a bicycle saddle. The electronic lock self-powered device comprises a bicycle saddle cushion, a sponge layer, a saddle cushion guide rail, a rack, a rack fixing plate, a generator track plate, a power generation system, a rack return spring, a gear set, a one-way clutch, a rectifier and a voltage stabilizing loop. Whereinthe bicycle seat cushion is fixed on the seat tube, the rack is vertically arranged in the sponge layer which is easy to extrude and deform through the rack fixing plate and moves in the vertical direction along with the deformation of the sponge layer, and the rack return spring can return the rack to the original position. The power generation system is fixed on the seat cushion guide rail through a generator track plate; a gear set meshed with the rack drives a rotor of the generator to rotate through a one-way clutch; therefore, bicycle seat cushion deformation caused by inclination of thebody of a rider in the riding process is converted into rotation of the motor rotor. The one-way clutch ensures that when the angular velocity of the inner side is smaller than the angular velocity of the outer side, the motor rotor on the outer side can continue to rotate by means of inertia, so that the generator generates more electric energy, a storage battery of the electronic lock system ofthe shared bicycle is charged through the rectifier and the voltage stabilizing loop, and power supply to the electronic lock system is completed.

    发明公开了一种安装于自行车座内的电子锁自供电装置,包括自行车座垫、海绵层、座垫导轨、齿条、齿条固定板、发电机轨道板、发电系统、齿条归位弹簧、齿轮组、单向离合器、整流器以及稳压回路。其中,自行车座垫固定在座管上,齿条通过齿条固定板竖直安装在易被挤压变形的海绵层内,并随着海绵层的变形发生竖直方向的位移,齿条归位弹簧可将齿条归于原位。发电系统通过发电机轨道板固定在座垫导轨上,与齿条啮合的齿轮组通过单向离合器带动发电机的转子转动,从而将骑手在骑行过程中由于身体的倾斜而造成的自行车座垫变形转化为电机转子的转动,单向离合器保证了当内侧的角速度小于外侧的角速度时外侧的电机转子可以依靠惯性继续转动,使发电机产生更多电能,进而通过整流器和稳压回路为共享单车的电子锁系统的蓄电池充电,完成对电子锁系统的供电。
