The invention discloses an electric bicycle wireless charging device, and belongs to the field of wireless charging, the electric bicycle wireless charging device comprises a pit formed in the ground and an output coil, the bottom of the pit is fixedly connected with an electric lifting rod, and the output end of the electric lifting rod is fixedly connected with a moving plate; a corrugated pipe is fixedly connected to the top of the moving plate, a supporting plate is fixedly connected to the interior of the corrugated pipe, multiple sets of sliding sleeves are arranged on the outer side of the top of the supporting plate in a circumferential array mode, ejector rods are slidably connected to the tops of the inner walls of the multiple sets of sliding sleeves, and jacking springs are arranged in the sliding sleeves; the two ends of the jacking spring abut against the bottom of the sliding sleeve and the ejector rod correspondingly, the ejector rod is pushed through tension of the jacking spring to keep thrust on the corrugated pipe, so that the corrugated pipe is expanded, and the top of the corrugated pipe is parallel to an output coil in the battery box. The influence of the deviation angle between the output coil and the input coil on wireless electric energy transmission is reduced, and the electric energy transmission efficiency is improved.

    本发明公开了一种电动自行车无线充电装置,属于无线充电领域,一种电动自行车无线充电装置,包括开设在地面的凹坑和输出线圈,所述凹坑底部固定连接有电动升降杆,所述电动升降杆输出端固定连接有移动板,所述移动板顶部固定连接有波纹管,所述波纹管内部固定连接有支撑板,所述支撑板顶部外侧圆周阵列有多组滑套,多组所述滑套内壁顶部均滑动连接有顶杆,所述滑套内部设置有顶升弹簧,所述顶升弹簧的两端分别与滑套底部和顶杆相抵,通过顶升弹簧的张力推动顶杆保持对波纹管的推力从而使波纹管进行扩张,使波纹管的顶部与电池箱内部的输出线圈平行,减少输出线圈与输入线圈之间偏移角度对无线电能传输的影响,提高电能传输的效率。
