The invention belongs to the technical field of bicycle structures, and particularly relates to a three-wheel folding self-locking bicycle frame with a self-balancing device. A main frame structure is formed by hinging a first movable connecting piece, a second movable connecting piece, a steering shaft connecting sleeve piece, a rear fork, a saddle stand column and a third connecting part; the third connecting part and the fourth connecting part are meshed with each other through a linkage device, the third connecting part and the fourth connecting part are meshed through linkage teeth to be matched with a downward pressing rear fork in the riding process to form the self-locking structure, and the self-balancing device is structurally characterized in that a steering shaft is hinged to a steering shaft sleeve. A front fork arm on one side of the front fork support below the steering shaft is hinged to a shock absorber supporting frame through a linkage device, the shock absorber supporting frame is hinged to a shock absorber supporting frame on the other side through a shock absorber, and the shock absorber supporting frame on the side is hinged to the front fork arm on the side through a linkage device. A sliding connecting rod hinged to the first connecting part is hinged to the handlebar rod through a transverse shaft to form a handlebar rod locking structure.

    本发明属于自行车结构技术领域,特别涉及一种具有自平衡装置的三轮折叠自锁自行车架,主车架结构是由活动连接件一与活动连接件二十字交叉铰接转向轴连接套件和后叉,车座立柱铰接连接部三,连接部三、连接部四之间通过联动装置相互啮合,所述自锁结构是由连接部三和连接部四之间通过连动齿啮合配合骑行时下压后叉构成自锁结构,自平衡装置的结构是由转向轴铰接转向轴套管,转向轴下方前叉支架一侧前叉臂通过联动装置铰接减震器支撑架,减震器支撑架通过减震器铰接另一侧减震器支撑架,所述这一侧减震器支撑架通过联动装置铰接这一侧前叉臂,连接部一上铰接的滑动连杆通过横向轴铰接车把杆构成车把杆锁紧结构。
