<p>A vehicle frame reinforcing and locking device comprises a vehicle beam (1) and a seat tube (3). Said vehicle beam (1) can be folded into at least two segments (11, 12). A hinge axle (81), through which various segments of the vehicle beam (1) are hinged with each other, is provided along the perpendicular direction. A reinforcement arm (2) is connected to the vehicle beam (1) and the seat tube (3), which is provided with a connecting device (32). The front end of said reinforcement arm (2) is hinged with the front segment (11) of the vehicle beam (1), and the tail end of the reinforcement ann (2) is connected with the seat tube (3) through the connecting device (32). The reinforcement arm (2) is locked by a locking device so that the position of the tail end of the reinforcement arm (2) after connected is deviated horizontally to the side of the hinge axle (81) of said vehicle beam (1) compared with an original position in natural connection. The vehicle frame reinforcing and locking device can rapidly fold or open the vehicle body, enhance the beam intensity and enable the foldable joining surface of the vehicle beam (1) with pre-tightening force, thereby achieving a reinforcing and locking device with good stability, simple structure and low cost.</p> |
