Abstract

The invention relates to a U secondary hinge, which includes an upper platform, a spherical hinge, an elastic member and a lower platform. Wherein the lower end surface of the upper platform is provided with a ball hinge limiting groove and a first annular limiting groove surrounding the spherical hinge limiting groove. The upper end of the spherical hinge is fixed in the limiting groove of the spherical hinge. The elastic member surrounds the circumferential periphery of the ball joint, and its upper end surface abuts against the first annular limiting groove. The upper end surface of the lower platform is provided with a second annular limiting groove for accommodating the lower end surface of the elastic member, and the lower end of the ball joint is fixed on the upper end surface of the lower platform. The U-pair hinge of the present invention has a self-resetting function and a function of rotation relative to a large angle range in the z-axis direction. After combining multiple U hinges, the hinge group will have a significantly increased working space.

Description

Technical field [0001] The present invention relates to the field of mechanical components, and more particularly to a u-state hinge, which is suitable for use in a vehicle, robot, and the like need to provide a field that can be rotated in a plane. Background technique [0002] In the mechanical equipment, it is necessary to set the U secondary mechanism that can be rotated in the plane in the mechanical equipment. However, the existing U branch is a problem of rigid collision between its components during exercise. In addition, the U branch also has a problem with a small working space. [0003] Document CN 109339606A discloses an adaptive triaxial hinge that automatically adapts to the housing door cover and a different process state of the housing door cover and a sealing material and a housing opening cover. However, its structure is complicated, easy to damage, small working space, and only the rotation of one direction is adaptive. [0004] The literature CN207830353U disc...
