Description

Hinge structure for split door Technical Field The invention relates to the field of vehicles, in particular to a hinge structure for a side-by-side vehicle door. Background Vehicles are an indispensable transportation means for modern life. At present, the opening and closing modes of the doors of the medium and small-sized passenger vehicles positioned at one side are generally divided into two modes, namely two doors opening and closing in the same direction or two doors opening and closing in opposite directions. Compared with a vehicle adopting a double-door same-direction opening and closing type vehicle door, the two vehicle doors on one side of the vehicle adopting the opposite opening type vehicle door are respectively opened to two sides, so that a larger door opening space can be provided, and convenience in getting on or off passengers is improved. However, in order to avoid the situation that the front door is blocked into the rear door and is difficult to open when a side collision occurs, the conventional vehicle with the side-by-side doors generally adopts a design that the front door presses the rear door, so that the front door needs to be opened before the rear door is opened when the door is opened, and the rear door cannot be opened independently. Thus, when only the rear-row passengers get on or get off, the front door still needs to be opened first, which not only increases the complexity of opening and closing the door, but also easily brings bad riding experience to the front-row passengers. The information disclosed in the background section of the invention is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. Disclosure of Invention Aiming at the defects in the prior art, the invention aims to provide a hinge structure for a side-by-side combination door, which can realize independent opening and/or closing of a front door and/or a rear door, thereby improving the convenience of opening and closing the door and improving the riding experience of passengers.
