The invention discloses a wheel folding and unfolding mechanism applied to a power-assisted tractor and a using method. The wheel folding and unfolding mechanism comprises a chassis shell. The upper bearing is connected with the chassis shell; the folding device is arranged on the chassis shell; and the wheels are connected with the folding device. An original welding mode is upgraded into a foldable mechanism, rapid folding and storage of the power-assisted tractor are achieved, the storage size of the whole tractor is reduced, and single-person operation is facilitated. When the motor extends, the gear and the rack act to tighten the tractor, when the motor retracts, the wheels are opened, and folding storage of the power-assisted tractor is automatically achieved. And linear motion of the electric cylinder is converted into rotation of folding storage through the gear and the rack, manual operation is not needed, and only one-key folding is needed. The folding storage mechanism has the advantages that the folding storage function of the upper half vehicle and the folding function of the wheels are achieved, the overall storage size is further reduced, carrying and mounting are convenient, and the practicability and portability of the mechanism are improved.

    本发明公开了一种应用于助力牵引车的车轮折叠收放机构及使用方法,包括底盘壳体;上部承载,所述上部承载与底盘壳体相连;折叠装置,所述折叠装置设置在底盘壳体上;车轮,所述车轮与折叠装置相连。具有将原有的焊接形式升级为可折叠的机构,实现助力牵引车的快速折叠收纳,减小整机收纳尺寸,便于单人操作。当电机伸长时,齿轮齿条作用将车辆收紧,电机收缩时,车轮打开,自动实现助力牵引车的折叠收纳。并通过齿轮齿条将电动缸的直线运动转化为折叠收纳的转动,无需人力操作,只需一键折叠。不仅具有上半车的折叠收纳同时还具有车轮的折叠功能,进一步缩小了整体的收纳尺寸,便于携带与安装,提高了机构的实用性与便携性性的优点。
