Novel scissor door

Abstract

The invention discloses a novel scissor door comprising car body installation parts, a car door outward-pushing mechanism, a car door rotating mechanism, and a car door body. The car door outward-pushing mechanism comprises a push rod, a connecting rod, a framework, and a rotating block mechanism; the car body installation parts, the connecting rod, the rotating block mechanism, and the frameworkform a four-bar linkage mechanism; the framework rotates around the installation axis of the framework by thrust of the push rod to drive the rotating block mechanism to rotate around a connecting axis of the framework and the rotating block mechanism; and a rotary motion of the rotating block mechanism is converted into a rotary motion of the car door rotating mechanism by a driving mechanism todrive the car door body to be rotatably opened and closed. Mechanism intensity is greatly enhanced by a special hinge structure design, the technical scheme using the four-bar linkage mechanism and agear transmission mechanism is skillfully used, and a car door opening angle of 90 degrees is achieved; the problem of difficulty in getting in and out caused by a small opening angle is solved; and car doors are opened and closed automatically by using the electric push rod, and the problem of difficulty in opening and closing of traditional scissor doors is solved.

Description

technical field [0001] The invention relates to the technical field of automobile doors, in particular to an automobile scissor door. Background technique [0002] The scissor door opens up and down through the hinges, which subverts the traditional way of opening the door outwards, so that it can open the door in a narrow area, avoiding the damage to pedestrians on the road or the door itself when the ordinary door is opened. The types of scissor doors can be roughly divided into three types: 1. Direct opening, that is, the door opening method goes straight up and down. 2. Outward opening type, in this way, it must be opened outward at a certain angle before it can be opened upward. 3. Hybrid type, this method can not only open outward like ordinary cars, but also open upward. At present, the scissor doors are mainly straight-opening and outward-opening. The current scissor door hinges have poor strength and low reliability, and are easily damaged, because the hinges tha...

Problems solved by technology

[0003] The purpose of the present invention is to address the deficiencies of the prior art, to provide a scissor door that can realize the automatic opening and closing of the car door and is suitable for most vehicle models. The technical solution of the four-bar linkage mechanism plus the gear transmission mechanism realizes the door opening angle of 90 degrees, which solves the problem of difficulty in getting on and off the car caused by the small opening angle of the door; the electric push rod can be used to realize the automatic opening and closing of the door, which solves the problem of traditional car door opening and closing.
