Abstract
(EN) The application discloses a self-generating device, comprising: a piezoelectric patch, the bottom of which is provided with a deformation space for accommodating the deformed piezoelectric patch; theoscillating mechanism comprises an elastic device and a mass block which are connected with each other; the oscillation triggering mechanism has a threshold triggering function and can be reset; the bottom surface of the mass block is in contact with the oscillation triggering mechanism; the elastic device can drive the oscillation triggering mechanism through the mass block after being stressed,so that the oscillation triggering mechanism abuts against the piezoelectric plate, and when the driving force borne by the oscillation triggering mechanism is larger than a triggering threshold value, the oscillation mechanism generates oscillation, the piezoelectric plate bears alternating loads, and multiple times of deformation are generated in the deformation space. According to the self-generating device provided by the embodiment of the invention, the oscillation mechanism is arranged, and the elastic device of the oscillation mechanism can drive the mass block to generate oscillation after being stressed, so that the piezoelectric plate generates multiple times of deformation in the deformation space, mechanical energy generated by oscillation of the mass block is converted into electric energy, and the generating capacity is greatly increased.
(ZH) 本申请公开一种自发电装置,包括:压电片,底部具有供容纳形变后的压电片的变形空间;振荡机构,包括相连接的弹性器件和质量块;带阈值触发且可复位的振荡触发机构,质量块的底面与振荡触发机构相接触;弹性器件受力后能通过质量块驱动振荡触发机构,使振荡触发机构抵压于压电片上,当振荡触发机构受到的驱动力大于触发阈值时,振荡机构产生振荡,使压电片受到交变载荷,并在变形空间内产生多次形变。本申请实施例提供的自发电装置,通过设置振荡机构,振荡机构的弹性器件受力后能驱动质量块,产生振荡,进而使压电片在变形空间内产生多次形变,实现将质量块振荡产生的机械能转换为电能,发电量大大增加。
