Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to an automobile top structure.

(Prior Art) Conventionally, open-top automobiles have generally been provided with a hood that covers the upper part of the vehicle body so that it can be opened and closed, and the hood has been opened and closed via a link mechanism to make it open or closed. However, in this type of convertible type, the opening and closing of the hood is complicated, the appearance is undesirable, and it is difficult to ensure the rigidity and strength of the upper part of the car body, so the roof part above the cabin is a highly rigid removable type. A rear hood consists of a roof panel and covers only the rear part of the inverted U-shaped foldable roll bar, and a link mechanism for raising and lowering the hood in conjunction with the roll bar is provided. A growing number of vehicles have rear hoods that can be opened and closed by raising and lowering the hood.

By the way, when covering only the rear part of the roll bar with the rear hood so that it can be opened and closed as described above, the length of the rear hood from the upper edge of the rear window provided in the center of the rear hood to the rear end of the roll bar is very long. As a result, the rear window had to be made smaller to save dimensions between the rear end of the roll bar when the roll bar is folded down and the upper edge (leading edge) of the rear window that falls forward. However, there is a problem in that the rear visibility in the closed state is deteriorated.

Therefore, for example, in U.S. Patent No. 3385629,
It is described that the rear window is separated from the periphery of the rear hood opening when the rear hood is stowed, but with this structure, the seal between the rear window and the rear hood opening is incomplete when the hood is retracted. It has the disadvantage of becoming boring.

(Purpose of the invention) The present invention was devised in view of the above-mentioned drawbacks, and is an automobile hood structure that allows the rear hood to be stored without downsizing the rear window and also ensures sealing performance when the hood is stretched. The purpose is to provide the following.

(Structure of the invention) The automobile hood structure according to the invention includes a rear hood that covers at least the rear part of the vehicle body, and a rear hood that spans between the left and right side walls of the rear part of the vehicle body, and is connected to both side walls via the left and right legs to the upright position and the rear part. A roll bar is connected to the front end of the rear hood so as to be rotatable in the longitudinal direction between the stowed position when the hood is laid down, and the front end of the rear hood is fixed. In an automobile equipped with a roll bar that switches the position between a stretched position and a stowed position, and a link mechanism that raises and lowers in conjunction with the roll bar and holds the rear hood in the stretched position, the rear hood has the following features: An opening for attaching a rear window is formed, and at least the upper half of the periphery of the opening is watertightly connected to the frame of the rear window via a bellows-shaped hood, and the bellows-shaped hood is arranged so that the rear hood is in the hooded position. When the rear top is switched to the storage position, it is held in a folded state between the rear hood and the rear window frame, and when the rear hood is switched to the stowed position, the top of the roll bar is above the rear window and the rear window is folded. It is provided so as to be extendable in the front-rear direction between the roll bar and the rear window so as to allow the roll bar to be laid down in a retracted position that is tilted backward from the front end.

(Function) In the automobile hood structure according to the present invention, when the roll bar is switched to the upright position, the rear hood is switched to the hooded position and held in an expanded state by the link mechanism. At this time, the bellows-shaped hood is held in a folded state between the frame of the rear hood and the rear window, and the periphery of the rear window and the periphery of the opening of the rear hood are watertightly connected via the bellows-shaped hood. Therefore, there is a complete seal between the opening and the rear window.

On the other hand, when the roll bar is switched to the retracted position, the rear hood is switched to the retracted position. At this time, the bellows-shaped hood extends in the front-rear direction between the roll bar and the rear window, and is lowered to the retracted position where the top of the roll bar is above the rear window and falls further back than the front end of the rear window. Therefore, the rear hood is stored in the storage position. In this way, the rear hood can be retracted without reducing the size of the rear window, so it is possible to maintain good rear visibility.

(Effect of the invention) In the automobile hood structure of the invention, as explained in the above (effects) section, the rear hood is provided with an opening for attaching a rear window, and at least the upper half of the periphery of this opening is Since it is watertightly connected to the rear window frame via the bellows-shaped hood, when the roll bar is switched to the stowed position and the rear hood is retracted, the bellows-shaped hood extends appropriately, and the rear window can be easily moved without downsizing the rear window. To be able to store the hood and maintain good rear visibility, and to be able to completely seal the periphery of the rear window and the periphery of the rear hood opening to ensure perfect sealing when the hood is up. Effects such as being able to do this can be obtained.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.
