摘要：近年来，共享经济在我国各大城市悄然兴起，而共享单车以其方便快捷、易于停放的特点，极大的方便了市民短距离出行。相关研究表明，虽然共享单车上载有太阳能板为车上的电源进行充电，但仍有很大概率会出现共享单车电源电量不足的情况，增加了运营管理的成本。随着移动设备的不断发展，手机已经成为现代人的生活必需品，由于手机功率不断提升与手机电池发展缓慢之间存在矛盾，共享充电宝也就应运而生。然而共享充电宝存在定点取存的缺点，在使用上仍有诸多不便。利用压电振子和交流发电装置，将共享单车行驶時的能量转换成电能，供给车上的电源。将共享充电宝租借平台安装在共享单车上，利用共享单车解决了共享充电宝借还困难的问题，同时能利用共享单车的电源为共享充电宝进行充电，能够有力解决前述两个主要问题。

Abstract：In recent years， the sharing economy has gradually emerged in major cities in China， and bicycle-sharing has greatly facilitated citizens' short distance travel due to their advantages of convenience and ease of parking. According to the relevant investigation and research， although the shared bikes are loaded with solar panels to charge the power supply， they are still likely to suffer from low power supply， which increases the management cost. With the continuous development of mobile devices， mobile phones have become indispensable devices for modern people. However，on account of the contradiction between the continuous improvement of mobile phone power and the slow development of mobile phone batteries， the shared charging pool came into being. Nevertheless， the shared charging treasure has the disadvantage of fixed-point storage， and it still has many inconveniences in use. Piezoelectric vibrators and ac generators are used to convert the energy of the shared bike into electricity， which is then used to power the vehicle. The shared charging treasure renting platform is installed on the shared bike， which solves the problem that the shared charging treasure is difficult to borrow. At the same time， the power supply of the shared bike can be used to charge the shared charging treasure， which solves the above two main problems.

Key Words： Shared bicycle; Shared power bank; Piezoelectric vibrator; Alternating current power generation

随着我国社会的快速发展，共享经济正在潜移默化地影响着人民的生活，其中最有代表性的当属共享单车和共享充电宝。共享单车是在“互联网+”的大背景下诞生的，它不仅改变了市民短距离出行的方式，成为了市民出行短距离换乘的首选交通工具，更响应了国家的低碳环保战略，丰富了市民短距离出行的方式^[1]。但是共享单车的GPS、蓝牙、智能车锁等模块依然会出现电能短缺的问题，给共享单车公司增加了成本，给用户的骑行带来了不必要的麻烦^[2-3]。……
