Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pillarless door structure for a vehicle.
[0002]
[Prior art]
Conventionally, in order to prevent the door from being deformed toward the interior of a vehicle at the time of a side collision (side collision), for example, as disclosed in Japanese Patent Laid-Open No. 2001-191879, the distance of a side collision object is pre-crash. It is known that a side collision is predicted by detection by a sensor, and when this side collision is predicted, a latch device is operated to protrude a pin, and the door and the rocker are locked by this pin.
[0003]
[Problems to be solved by the invention]
However, even if the door is locked to the rocker by the latch device due to the prediction of side collision, if there are pillars on both the front and rear sides of the door, the door is bound to the pillars by the door lock device and hinges, Combined with the restraint on the rocker by the latch device, it is possible to effectively suppress the amount of deformation toward the vehicle interior at the time of a side collision, but there is no pillar between the doors adjacent to each other like the pillarless door In this case, since the door support is cantilevered, the door restraint effect by the latch device cannot be sufficiently obtained, and the deformation amount of the door at the time of a side collision becomes large.
[0004]
Therefore, the present invention provides a pillarless door structure for a vehicle that can effectively disperse a collision load at the time of a side collision to the vehicle body side and can effectively suppress deformation of the door.
[0005]
[Means for Solving the Problems]
In the present invention, a first door provided on the side surface of the vehicle body is provided, and a second door is disposed adjacent to the rear side of the first door in a pillarless state, and the first and second doors are independently provided. In a pillar-less door structure for a vehicle that opens and closes and has door lock devices on the upper and lower sides of the first door adjacent to the second door,
Inside the first door, an extrusion member having a hollow portion formed with a pulling angle substantially parallel to the inclination angle of the door sash on the side of the door lock device is disposed, and the upper and lower door lock devices are arranged on the extrusion member. Installation,
A first passage hole that communicates with the upper door lock device and a second passage hole that communicates with the lower door lock device are formed in the push member substantially in parallel with the extraction angle of the hollow portion, and the first and second passage holes are formed. Forming a storage space that leads to
A door lock actuating member is installed in the storage space, and an operation cable connecting the door lock actuating member, the upper door lock device, and the lower door lock device is routed in the first and second passage holes. It is said.
[0006]
【The invention's effect】
According to the present invention, when a side impact load is input to the first door, the impact load is efficiently transmitted to the upper and lower door lock devices via the pushing member having high strength and rigidity, and these door lock devices are provided. Therefore, the side impact energy of the first door can be absorbed by the entire vehicle body and the cabin deformation can be effectively suppressed with a simple structure.
[0007]
In addition, the operation cables of the upper and lower door lock devices are respectively routed in the first and second passage holes formed in the pushing member, so that the operation cables are simply inserted into the first and second passage holes and fixed.
