Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof device for an electric vehicle capable of forming a state in which a seat portion is covered and a state in which the seat portion is stored.

[0002]

2. Description of the Related Art Conventionally, an electric vehicle that can travel at a slow speed instead of walking has been used. When using such an electric vehicle, it is desired to protect the driver in the rain so that the driver does not get wet with the rain and, if the sunshine is strong, the driver is protected from the sun. Conventionally, there is also a type in which a small roof is formed by expanding a seat portion so as to cover an upper portion of a seat of an electric vehicle, but since the folding is a bellows type, a frame for forming a plurality of bellows is required. In addition, the plurality of bellows frames are rotatably supported on the pillar at one place, and since the bellows frame makes a circular motion by opening and closing, the bellows that spread forward from the pillar form an arc-shaped roof. Will be done. For this reason,
When the pillar is low, the tip of the roof covers the front of the line of sight of a person sitting on the seat, and it becomes annoying. To avoid this, it is necessary to raise the pillar or increase the turning radius of the bellows frame. In this way, the device becomes tall and large, and it is difficult to make it compact even when folded.

Further, in a system in which other pipes having bellows frames are inserted into the left and right strut pipes so that they can slide relative to each other, and which is housed low in the back of the seat, the other strut pipes are not included. It is necessary to slide the pipe to set the roof at a predetermined height, and then to open the roof, and to separate the operation of opening and closing the roof from the vertical movement.

[0004]

SUMMARY OF THE INVENTION In view of the above, the present invention adopts a mechanism different from the conventional mechanism so that the roof member covers the upper portion of the seat portion of the electric vehicle and the electric vehicle. (EN) Provided is an electric vehicle roof device which can be stored in the back of a vehicle seat by a series of simple operations. Further, there is provided an electric vehicle roof device capable of changing the height of the roof to a height suitable for a driver.

[0005]

In view of the above, the present invention has been made in view of the above.
A roof device for an electric vehicle is an electric vehicle having a roof that covers an upper portion of a seat portion of the electric vehicle. The roof device is rotatably supported by a fixing member provided on the rear side of the seat portion, and a position raised and lowered by the rotation. And a second roof column rotatably supported above the fixing member, so that the front end of the first roof column and the rear part of the roof are rotatable. The front end of the second roof pillar and the middle portion of the roof are rotatably connected.
The roof is placed above the seat at a raised position of the first roof pillar, and the roof is stowed behind the seat at a lowered position of the first roof pillar. A mechanism is provided in which one roof pillar and the second roof pillar rotate together.

As described above, there is an effect that a state in which the roof covers the upper part of the seat portion and a state in which the roof is housed in the back portion of the seat portion can be performed by a series of operations. Therefore, as compared with the bellows system in which a plurality of bellows frames are rotated with respect to the support as described above, the state in which the roof material is set above the seat portion and the storage in the back portion of the seat become easy, The structure can be simplified.

Further, according to the present invention, in an electric vehicle having a roof covering an upper portion of a seat portion of the electric vehicle, the roof comprises a sheet-shaped roof member and a roof frame member for holding the roof member in an expanded state. A first roof strut that is rotatably supported by a fixing member provided on the rear side of the seat portion and takes a raised position and a lowered position by the rotation, and a second roof rotatably supported above the fixing member. A roof strut, and a tip end portion of the first roof strut and a rear portion of the roof frame member are rotatably connected, and a tip end portion of the second roof strut and an intermediate portion of the roof frame member rotate. Operably connected to the first
The first roof pillar is so arranged that the roof covers the upper part of the seat portion at a raised position of the roof pillar, and the roof is stored at the rear side of the seat portion at a lowered position of the first roof pillar. And a mechanism for rotating the second roof pillar in conjunction with each other.

As a result, even when the roof is composed of a sheet-shaped roof material and a roof frame material that holds the sheet-shaped roof material in an expanded state, the roof material covers the upper portion of the seat portion and is housed on the rear side of the seat portion. You can move in stable condition.

Further, the present invention is characterized in that, in the above structure, the fixing member is configured to be movable up and down, and the height of the roof can be changed by the vertical movement. As a result, the height can be changed according to the sitting height of the seated person or the desired height.
