The invention discloses an anti-falling device modified from a middle support. The anti-falling device is structurally formed by connecting a shared rear wheel brake handle, an additionally-arranged pull wire, a newly-added pull wire fixing frame and the modified middle support in a matched mode. The outer side of the rear wheel brake handle is connected with a traction arm and the other section of drum head positioning plate, the lower portion of a bottom beam of an electric vehicle is connected with the fixing frame, the pull wire is connected between the other section of drum head positioning plate and the fixing frame, and the pull wire and the shared rear wheel brake handle form a linkage mechanism after the pull wire is connected with the middle support through a triangular rope. When a rear wheel brakes abruptly, the traction arm is driven by the shared rear wheel brake handle to pull the middle support to rotate downwards through the pull wire and the triangular rope to form inclination, two trundles arranged below the middle support are grounded synchronously due to the fact that the middle support inclines downwards, and the two grounded trundles play a role in supportingbalance during emergency braking of the vehicle body.
一种由中支撑改制的防摔倒装置,结构由共用后轮刹车把,另设的一条牵引线,新增的牵引线固定架和改制后的中支撑配套相连组成;在后轮刹车把的外侧分别连接牵引臂和另一段鼓头定位板,在电动车的底梁下面连固定架,在另一段鼓头定位板、固定架之间连接牵引线,牵引线通过三角绳和中支撑相连后与共用后轮刹车把形成联动机构,后轮急刹时,由共用后轮刹车把带动牵引臂通过牵引线、三角绳拉动中支撑向下做旋转后形成倾斜,中支撑的向下倾斜使得设置在中支撑下面的两个脚轮同步接地,接地的两个脚轮对车体急刹时的平衡起到了支撑的作用。
