Description

Technical Field

[0001] The utility model relates to the technical field of accessories for cargo boxes, in particular to a hidden connecting rod hinge structure for opening a side door of a cargo box by 180 degrees. Background Art

[0002] For light truck cargo boxes with side doors, the side doors are generally assembled with hinge structures and rotatably connected to the side walls of the cargo box to enable opening and closing during cargo loading and unloading. Currently, the structures used to achieve the hinged connection between the side doors and the side walls of the cargo box are all installed and exposed on the outer surface of the cargo box. They are exposed to the external environment for a long time and are susceptible to corrosion and wear, requiring irregular inspection and maintenance. In addition, since the hinged components will always be in a state of protruding from the surface of the cargo box after installation, it is difficult for the side doors of the cargo box to be fully opened 180°. When the side doors of the cargo box are opened to the maximum angle, the maximum protruding point of the hinged components will contact the surface of the side doors or the side walls of the cargo box, which is likely to cause wear on the surface of the side doors or the side walls of the cargo box, thereby affecting the aesthetics of the exterior of the cargo box. When the surface is worn, it will also accelerate rust, thereby reducing the service life of the side doors or the side walls of the cargo box. Utility Model Content
