The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

An elastic supporting structure capable of adaptively adjusting postures is shown in fig. 1 to 4, and comprises a lower supporting seat 1, an upper supporting seat 2 and a spring 3 arranged between the lower supporting seat and the upper supporting seat; the lower support seat comprises a lower base body 4 and a lower boss 5 on the upper side of the lower base body, and the upper support seat comprises an upper base body 6 and an upper boss 7 on the lower side of the upper base body; the lower end of the spring is sleeved outside the lower boss, and the upper end of the spring is sleeved outside the upper boss.

The upper end face of the lower base body is a plane, the lower end face of the upper base body is an inclined plane 8, the upper end of the spring abuts against the lower end face of the upper base body, and the lower end of the spring abuts against the upper end face of the lower base body. In a normal state, the upper base body and the lower base body are horizontally arranged, after loading, the lower boss of the lower end of the spring is allowed to be self-adaptively rotated and adjusted, the posture of the spring (and the upper supporting seat) can be self-adaptively aligned, the moment increased by the torsion of the spring is effectively reduced, the lower end face of the upper supporting seat is designed to be an inclined face, the stress when the spring is integrally bent in a C shape can be reduced, and the service life of the spring is prolonged.

The lower side of the lower base body is provided with the lug plate 9, the lug plate is provided with the shaft hole 10, the lower supporting seat can swing by taking the axis of the shaft hole as the center, the elastic shock absorption is realized by utilizing the spring, the angle of the lower supporting seat can be adjusted in a self-adaptive mode, and the stress condition of the spring and the whole supporting structure is improved.

In order to improve the stability of the spring, the upper end and the lower end of the spring are respectively provided with a plane part.
