Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the invention, fall within the scope of protection of the invention.
Two parts are arranged for connecting the vehicle door and the vehicle body together, one is a hinge, the other is a limiter, and the limiter plays a role in limiting the opening angle of the vehicle door. The hinge is used for supporting the vehicle door, so that the vehicle door is firmly hung on the vehicle body and can move.
The door of a traditional vehicle usually adopts a front door opening design, and as the name implies, the front door opening means that all side doors of the vehicle adopt a mode of opening forwards, four side doors are usually arranged, two side doors are arranged front to back, the front side door is usually connected with a vehicle A column through a hinge, and the rear side door is connected with a vehicle B column through a hinge. Because the space available for connecting the doors is relatively large provided by the A-pillar and the B-pillar, typically one side door is connected to the corresponding pillar by at least two sets of hinges, in such a manner as to ensure that at least two support stress points are formed between the side door and the pillar to prevent sagging of the side door.
In the vehicle adopting the side-by-side door type, although two side doors are respectively arranged at the front side and the rear side of the vehicle, only the front side door is consistent with the connecting part of the side door of the traditional front door vehicle. The vehicle door at the rear needs to be connected with the vehicle body below the C column to ensure that the rear vehicle door is pulled backwards to be opened. Because the body below the C-pillar provides a relatively small space for mounting the hinge, the prior art side-by-side vehicles typically employ a rear door to body connection in accordance with a conventional hinge. Because a hinge can only provide a supporting stress point, the side door of the side-by-side vehicle at the rear is extremely prone to door sagging. In addition, even if two conventional hinges are used to connect the rear side door, the span between the two hinges is relatively small due to the limitation of installation space, and the problem of door sagging also occurs.
In order to solve the above-mentioned problem, this application embodiment provides a door hinge mechanism, this structure is through the member as the first connecting piece and the connection transfer piece of door welding assembly, is provided with two at least first connecting pieces on every member, and each first connecting piece can correspond and link to each other with the each second connecting piece of automobile body welding assembly, can make door welding assembly and automobile body welding assembly form rotatable linking to each other, can provide two at least support stress points again, reaches the purpose that prevents the door sagging.
Meanwhile, due to the fact that the two independent hinges are arranged up and down, the stress of the hinge located above is larger than that of the hinge located below, and the situation that the hinge located above is damaged and normal use is affected due to stress fatigue is easily caused. And the first connecting piece that this application embodiment provided passes through the member and connects and form an organic whole structure for the gravity of door welding assembly can be distributed to each second connecting piece by more even, makes first connecting piece and second connecting piece hookup location department atress more balanced, avoids appearing the long-time too big problem that takes place fatigue damage of atress of top hinge.
