A kind of door hinge assembly

Abstract

The invention discloses a car door hinge assembly. The assembly comprises a first hinge blade, a second hinge blade, a sliding shaft and a fixed shaft; the first hinge blade is fixedly connected with a car door, a first sliding groove is formed in the first hinge blade, the second hinge blade is fixedly connected with a car body, a second sliding groove is formed in the second hinge blade, one end of the sliding shaft is fixedly connected with the first hinge blade, the other en of the sliding shaft extends to the second sliding groove, and the sliding shaft can slide in the second sliding groove; one end of the fixed shaft is fixedly connected with the second hinge blade, the other end of the fixed shaft extends to the first sliding groove, and the fixed shaft slides in the first sliding groove while the sliding shaft slides in the second sliding groove. The sliding shaft and the fixed shaft are arranged, when the car door is opened or closed, the sliding shaft and the fixed shaft can slide in the corresponding sliding grooves at the same time, the opening angle of the car door is enlarged, and the interference of the car door and the periphery is avoided.

Description

technical field [0001] The invention relates to the technical field of hinges, in particular to a door hinge assembly. Background technique [0002] In the prior art, the hinge structures of various doors are basically fixed axis structures. For car doors, the fixed axis is generally fixed on the vehicle body, and then the hinge is fixed on the car door. The fixed axis passes through the hinge, and the hinge can move along the fixed axis. The shaft rotates, thereby driving the door to open and close. [0003] However, the current car door hinge structure can only rotate within a limited angle. In some special cases, the door interferes with peripheral parts after opening. The only way to avoid interference between the door and peripheral parts is to artificially control the opening angle of the door. : Opening the door to 80 degrees is the best opening angle, but due to interference problems, the door can only be opened 65 degrees as carefully as possible, which is not only...

Problems solved by technology

[0003] However, the current car door hinge structure can only rotate within a limited angle. In some special cases, the door interferes with peripheral parts after opening, and the door opening angle can only be controlled manually to avoid interference between the door and peripheral parts. For example : The best opening angle is when the door is opened to 80 degrees. However, due to interference problems, the door can only be opened to 65 degrees as carefully as possible. This is not only difficult to operate, but also the door may still be disconnected from the surrounding area due to slight touches. interference
