AI Technical Summary
Technical Problem
When riding a bicycle uphill or accelerating, the driving torque is low when the pedals are near the top dead center, leading to leg fatigue.
Method used
A flexible crank structure for bicycles with compensation function was designed. Through the cooperation of auxiliary rod, movable rod and spring, the elastic element provides flexible push near the top dead center to relieve leg fatigue. At the same time, the connecting mechanism and the limiting mechanism ensure the stable connection between the crank and the main shaft.
Benefits of technology
It effectively alleviates leg fatigue when riding uphill or accelerating, and ensures a firm connection between the crank and the spindle, improving riding comfort and efficiency.

Abstract
本发明涉及自行车曲柄技术领域，且公开了一种具有补偿功能的自行车柔性曲柄结构，解决了目前上坡或加速骑行时容易出现腿困疲劳的问题，其包括曲柄，所述曲柄的外侧设有主轴，曲柄与主轴之间安装有连接机构；本发明，通过辅助杆和活动杆二之间的配合，当自行车上坡或加速骑行踩蹬脚踏板时，便于滑块一沿着L型圆杆滑动，继而使得弹簧一被压缩，并通过活动杆一和滑块三之间的配合，使得弹簧三被压缩，并通过安装辊和安装框以及U型圆杆和滑块二之间的配合，使得弹簧二被压缩，便于弹簧一和弹簧三以及弹簧二在上止点附近起作用呈柔性推动，便于脚踏板被轻松推越上止点，从而便于缓解上坡或加速骑行时出现的腿困疲劳感。
