Trackless side sliding door mechanical structure of vehicle

Abstract

The invention discloses a trackless side sliding door mechanical structure of a vehicle. A main traction arm and an auxiliary traction arm are arranged on a side sliding door; the main traction arm comprises a side wall end support, a connecting rod support with a rotating shaft, a main arm connecting rod, a connecting rod reinforcing piece with a rotating shaft and a vehicle door inner plate support which are sequentially connected. The auxiliary traction arm is composed of a side wall end support, an auxiliary arm connecting rod with a rotating shaft and a vehicle door inner plate end support. The device is composed of a support with a guide groove, a door lock connecting rod with a guide rolling shaft, a door lock and an electric supporting rod. And a lock pin rod matched with the front end of the side sliding door can slide into the opening of the door lock to be clamped with the door lock. By means of the main traction arm, the auxiliary traction arm and the guide mechanism, the constraint of a guide rail to the shape is eliminated, the vehicle door is opened in a backward sideslip mode and closed stably in a forward mode, the structure is novel, stability is high, and the extremely high application value is achieved.

Description

technical field [0001] The invention relates to a slidingly opened side sliding door of a vehicle, in particular to a mechanical structure of a trackless side sliding door of a vehicle. Background technique [0002] At present, in the industry, the sliding side sliding doors of vehicles basically adopt a structure with tracks, and the side doors are opened by sliding in the tracks. A typical structure is as follows: figure 1 , 2 As shown, the structure of the side sliding door is mainly the right sliding track, which is realized through the technical solution with tracks: by arranging the guide rails (1) of the target track on the upper and lower parts of the side wall, the door passes through the hinge assembly with guide wheels ( 2) The structure makes the guide wheel (21) slide along the track on the guide rail, so that the door can be opened rearwardly. Among them, the guide rail (1) is fixed on the upper and lower ends of the side wall of the vehicle body through posi...

Problems solved by technology

As for the railed sliding door, since the guide rail is a functional component, it must first match the sliding track of the door. The curve of the guide rail directly determines that the door can only form a side sliding and straight track. Therefore, the track curve at the top of the side wall must be straight, which cannot be achieved. The requirements of the slippery back curve; to a large extent, it limits the various aesthetic designs of the body appearance, and it is difficult to meet the needs of users who purchase mid-level and high-end vehicles for the appearance of the body.
