Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upper vehicle body structure of an automobile, and more particularly to an upper vehicle body structure in which first and second hard roofs are displaceably provided at a rear portion of a main roof.

(Prior Art) Conventionally, in an automobile, a roof portion is movable in a front-rear direction of a vehicle body, and it is known that a rear space of a vehicle compartment can be expanded or contracted by moving the roof portion. (See, eg, US Pat. No. 4,168,859 and drawings).

(Problems to be Solved by the Invention) However, in a conventional vehicle in which the roof portion is movable in the front-rear direction of the vehicle body, the vehicle interior is opened to the outside by moving the roof portion. However, there is a problem that the occupant in the vehicle cabin gets wet when the roof is moved during rainfall.

Therefore, for the purpose of being able to extend the vehicle compartment space for traveling regardless of weather conditions, the present inventor hinge-couples the rear portion of the main roof constituting the upper portion of the vehicle body and the rear deck of the vehicle body with each other. The first hard roof and the second hard roof located on the vehicle rear side of the first hard roof are displaceably provided so as to have a plurality of states, and the hard roofs are expanded or folded. By doing so, we have developed an upper body structure of an automobile that can expand or reduce the passenger compartment space and filed a separate application.

However, in such a structure, there is a demand for automatically expanding or folding the first and second hard roofs.

Therefore, it is an object of the present invention to provide an upper body structure of an automobile capable of automatically expanding or folding both hard roofs in the above structure.

(Means for Solving the Problems) In order to achieve the above object, a solution means of the present invention is a first hard roof hinged to each other between a rear portion of a main roof constituting an upper part of a vehicle body and a rear deck of the vehicle body. And a second hard roof located on the vehicle rear side of the first hard roof so as to be displaceable so as to have a plurality of states, and by expanding or folding the both hard roofs, the vehicle interior space is expanded or It is premised on the upper body structure of a car that can be reduced. One end of the second hard roof is rotatably supported by a fixed part of the vehicle body, and the other end is connected to both hard roof coupling parts of the first or second hard roof. A link member that rotates in the vertical direction along the wall surface is provided.

(Operation) As a result, by driving the drive means, the link member is rotated and the first and second hard roofs are expanded or folded. Since the link member rotates along the inner wall surface of the second hard roof, there is no displacement in the left-right direction of the vehicle body.
It doesn't get in the way.
