Door cover gravity balance hinge structure

The invention belongs to the technical field of vehicle-mounted equipment, and particularly relates to a door cover gravity balance hinge structure. Comprising a hinge base assembly, a hinge upper hinge assembly and a hinge rotating shaft assembly, the hinge base assembly comprises a hinge base, a gear damper and a damper mounting bolt, and the hinge rotating shaft assembly comprises a hinge rotating shaft, a main torsion spring, a clutch disc, a reverse torsion spring, a rotating shaft rotation stopping lining, an axial limiting lining and an E-shaped clamp. The hinge upper leaf assembly comprises a hinge upper leaf and a damping fluted disc, a hinge upper leaf main torsion spring hinge upper leaf clutch plate hanging point groove is formed in the hinge upper leaf, and a hinge base main torsion spring hinge upper leaf clutch plate hanging point groove is formed in the hinge base. Through the arrangement of the torsion spring and the clutch disc, the reverse torsion spring is used for improving the reverse ac
