The folding bicycle comprises a bottom connecting rod set, a front frame, a rear frame, a stand column rod set, a wheel set and two side frames, each side frame comprises an X assembly and four cross beams, each X assembly comprises a first oblique beam and a second oblique beam which are hinged through a hinge shaft arranged in the middle of the X assembly, the number of the side frames is two, and the side frames are oppositely arranged; the cross beams are used for connecting the stand column rod set and the X assembly, the stand column rod set is used for connecting the two cross beams, the front frame and the rear frame which are oppositely arranged in the vertical direction, the bottom connecting rod set comprises four bottom rods and a center connecting piece, and the wheel set is connected with the bottom connecting rod set. Each side frame of the folding bicycle only comprises one X assembly, compared with an existing folding bicycle, cross point structures are reduced, the failure rate of the folding bicycle is reduced, meanwhile, the four cross beams are additionally arranged to be used for connecting the X assemblies and the stand column rod sets, the bearing space and the bearing capacity of the folding bicycle are guaranteed, the cross beams and the X assemblies jointly form a surface support of the folding bicycle, and the folding bicycle is more convenient to use. And the bearing capacity of the folding bicycle is further improved.
本发明公开了一种折叠车,包括底部连杆组、前架、后架、立柱杆组、车轮组和侧架,侧架包括一个X组件和四个横梁,X组件包括通过设置在自身中间的铰接轴铰接的第一斜梁和第二斜梁,侧架的数量为两个,且相对布置,横梁用于连接立柱杆组和X组件,立柱杆组用于连接在竖直方向上相对布置的两个横梁、前架和后架,底部连杆组包括四根底杆和一个中心连接件,车轮组与底部连杆组相连接。折叠车每一个侧架只包括一个X组件,相对于现有的折叠车减少了交叉点结构,降低了折叠车的故障率,同时另外布置有四个横梁用于连接X组件和立柱杆组,保证了折叠车的承重空间和承重能力,且横梁与X组件共同形成折叠车的面支撑,进一步提高了折叠车的承重能力。
