The linkage folding structure of the manned folding electric trailer comprises a folding trailer body, the two ends of the folding trailer body are provided with inner supporting rods and outer supporting rods which are arranged in a sliding and sleeving mode, the two outer supporting rods at at least one end are rotationally connected with linkage mechanisms correspondingly, and one end of each linkage mechanism is rotationally connected with a direction control mechanism; at least one first wheel is connected to the lower portion of the direction control mechanism, the linkage mechanism is used for pulling the direction control mechanism to move and limiting rotation of the direction control mechanism, and the folding vehicle body is further provided with a second wheel, a controller and a power source; by the adoption of the design, the pedal rod is connected with the outer supporting rod, the pedal rod and the direction control mechanism are synchronously driven to be folded when the folding bicycle body is folded, rotation of the first wheel relative to the pedal rod is limited through the arrangement of the rotation limiting rod, and the folding bicycle does not need to be folded additionally, is simpler, more convenient and faster to use, meanwhile, is reasonable in structure, guarantees supporting and is convenient to use. And the structure is simpler, limiting structures do not need to be arranged on the foot bar and the outer supporting rod, and the production cost is effectively reduced.
本申请公开一种可载人折叠电动拖车的联动收折结构,包括:折叠车体,折叠车体的两端设有滑动套设的内支撑杆和外支撑杆,至少一端的两个外支撑杆分别转动连接有联动机构,联动机构的一端转动连接有控向机构,控向机构的下方连接有至少一个第一车轮,联动机构用于拉动控向机构移动及限制控向机构转动,折叠车体还设有第二车轮、控制器及电源;采用以上设计,通过将踏杆与外支撑杆连接,实现折叠车体在收折时同步带动踏杆和控向机构收折,通过限转杆的设置,限制第一车轮相对踏杆的转动,本申请收折无需另做收折动作,使用更简单,方便快捷,同时结构合理,支撑有保障,且结构更简单,无需在踏杆和外支撑杆上做限位结构,有效的降低生产成本。
