Door device and passenger car employing door device

Abstract

The invention discloses a door device and a passenger car employing the door device. A door plank of the door device is a folding door plank, and the hinge axes of folding hinges of the folding door plank are parallel to the hinge axes of turnover hinges, in this way, in use, under the condition that a luggage compartment needs to be sealed, an opening of the luggage compartment is sealed in a manner that the folding door plank is turned over wholly through the turnover hinges and then unfolded; when the luggage compartment needs to be opened, the folding door plank avoids the opening of the luggage compartment in a manner that deflecting plates of the folding door plank are deflected; the opening extent of the opening of the luggage compartment is further increased in a manner that the folding door plank is upturned through the turnover hinges. Therefore the door device has the advantage that the utilization rate of inside and outside spaces of a compartment body is increased.

Description

technical field [0001] The invention relates to a cabin door device and a passenger car using the cabin door device. Background technique [0002] At present, the door panels of the side doors of the luggage compartment of domestic passenger cars are mostly stamped from steel plates, and the inside of the door panels are provided with reinforcing ribs to increase the overall rigidity of the door. Commercially available passenger car doors mainly have two structures: one is upturned, such as figure 1 As shown, the hatch and the body compartment are fixed together by the hinge 102. When the hatch 101 is opened, the hatch 101 moves in a circular arc with the central axis of the hinge 102 as the axis of rotation. There are air support springs 103 on both sides of the hatch 101. After opening, it is supported by air-supported springs, so that the opening method of this swing-out hatch requires relatively large space on both sides of the vehicle body. If this kind of luggage com...

Problems solved by technology

[0002] At present, the door panels of the side doors of the luggage compartment of domestic passenger cars are mostly stamped from steel plates, and the inside of the door panels are provided with reinforcing ribs to increase the overall rigidity of the door. Commercially available passenger car doors mainly have two structures: one is upturned, such as figure 1 As shown, the hatch and the body compartment are fixed together by the hinge 102. When the hatch 101 is opened, the hatch 101 moves in a circular arc with the central axis of the hinge 102 as the axis of rotation. There are air support springs 103 on both sides of the hatch 101. After opening, it is supported by air-supported springs, so that the opening method of this swing-out hatch requires relatively large space on both sides of the vehicle body. If this kind of luggage compartment door is installed, the space on both sides of the parking space must be at least 5 meters, thereby reducing the number of vehicles parked in the station, and reducing the utilization rate of parking spaces in the station; another type of upward movement, such as Chinese patent document 201420024404.X discloses a passenger car luggage compartment door translation device, such as figure 2 As shown, the door panel 201 and the cabin body are connected by a triangular pivot arm 202. When the cabin door is opened using the principle of the four-bar linkage mechanism, the cabin door 201 and the vehicle body can keep a small distance and move upwards in parallel. The external space does not need to be too large, but when the cabin door is closed, the triangular arm 202 will occupy a huge cabin space, resulting in a sharp drop in the utilization rate of the cabin space. In long-distance tourist passenger transport, especially the Spring Festival travel passengers carry a lot of luggage , but this structure hinders the carrying of a large amount of luggage. In summary, the hatch devices of the two structures fail to make good use of the space, resulting in a waste of resource costs
