The double-wheel transfer trolley with the parking automatic braking mechanism comprises a frame and two wheels, a traction handle rod is arranged at the front end of the frame, braking parts are arranged on the front sides of the wheels, the upper ends of the braking parts are hinged to the frame, and the rear sides of the braking parts are provided with braking faces; a brake rod is arranged on the front side of the brake part and comprises an inclined rod body, and the upper end of the rod body is hinged to the frame; a limiting rod and an ejector rod are arranged at the upper end of the rod body, a baffle matched with the limiting rod in a stopping mode is fixed to the frame, and the ejector rod is used for abutting against the brake part after rotating along with the rod body. The double-wheel transfer trolley further comprises a first elastic piece installed between the braking piece and the trolley frame. During use, when a vehicle needs to be parked or stored in a certain position, the traction handle rod is directly put down, the lower end of the brake rod body makes contact with the ground, the rod body rotates, the ejector rod ejects the brake piece backwards, the braking function is achieved, namely parking automatic braking can be achieved by putting down the traction handle rod, use is very convenient, additional operation is not needed, and the cost is low. And the danger caused by forgetting to brake is avoided.

    本发明提供了一种带驻车自动刹车机构的双轮转运车,包括车架和两个车轮,车架前端设有牵引把杆,车轮前侧设有制动件,制动件上端铰接在车架上,后侧具有制动面;制动件前侧设有刹车杆,刹车杆包括倾斜的杆体,杆体上端铰接在车架上;杆体上端设有限位杆和顶杆,车架上固定有与限位杆挡止配合的挡板,顶杆用于随杆体转动后顶压在制动件上;双轮转运车还包括安装在制动件和车架之间的第一弹性件。使用时,当车辆需要停放或储存在某一位置时,直接下放牵引把杆,刹车杆杆体下端与地面接触,杆体发生转动,顶杆向后顶压制动件,实现刹车功能,也即放下牵引把杆即可实现驻车自动刹车,使用非常方便,不需要额外操作,也不用担心会忘记刹车而造成危险。
