Abstract

The present utility model relates to the field of seats, and in particular to an automatic folding seat. The automatic folding seat comprises a seat body, a supporting structure, and elastic devices. First supports are hinged to the left ends of the bottom surfaces of the seat body, and second supports are hinged to the right ends of the bottom surfaces of the seat body. The elastic devices are hinged to the first supports and the second supports, the lower ends of the first supports are bent leftward, the lower ends of the second supports are bent rightwards, and pulleys are arranged at the lower ends of the first supports and the second supports. When the automatic folding seat changes from a folded state to an unfolded state, the first supports rotate leftward under the influence of weight, the second supports rotate rightward under the influence of weight, and the pulleys slide along with the first supports and the second supports until rotation angles of the first supports and the second supports relative to the seat body are maximized. When supporting legs are not completely opened and are in contact with the ground, since the supporting legs can be opened to a specific state due to the weight of a human body, during said period, the pulleys can reduce friction force with the ground, so that the supporting legs are not prone to damage.

Description

An automatic folding seat

Technical field

The utility model relates to the field of seats, in particular to an automatic folding seat.

Background technique

The Chinese patent with publication number CN110236320A provides a seat, including a seat base and a fixing device, wherein the fixing device is connected to the seat base, and the seat base can be deformed into two structural states. When the seat base is in the first structural state, the structure of the seat base is unfolded to support the human body, and the connecting rod is in contact with the ground. By setting the connecting rod, the contact area between the seat base and the ground is increased, thereby increasing the friction between the seat base and the ground, preventing the seat base from sliding, which is beneficial to the stability of the seat base. In addition, in order to further increase the friction between the seat base and the ground, a rubber sleeve is put on the outside of the connecting rod. The problem of the prior art is that when the connecting rod contacts the ground in a state that is not fully opened, the gravity of the human body will open the connecting rod to a specific state. During this period, the friction between the connecting rod and the ground is greater than the expected friction, and the connecting rod is easily damaged.
