Description

TECHNICAL FIELD The present invention relates to a canvas top structure of a vehicle including a canvas that covers a roof opening portion in an openable and closable manner. The present invention relates to a canvas top structure of a vehicle.

Prior Art In a vehicle equipped with a canvas that covers the roof opening in an openable and closable manner, a negative pressure part is generated on the roof surface by the wind that flows over the roof at high speeds, and the canvas is sucked upward, Since it becomes difficult to open and close, a deflector extending in the vehicle width direction is provided at the front edge of the roof opening to disturb the wind flow behind the deflector and reduce the occurrence of negative pressure parts on the roof surface. Vehicle canvas top structures are known (eg,
No. 60-81128, etc.).

However, even in the canvas top structure of the vehicle in which the deflector extending in the vehicle width direction is provided at the front edge of the roof opening portion as described above, the region of wind disturbed by the deflector is Is limited to a certain area behind
It is unavoidable that a negative pressure part is generated in the rear part of the roof opening. Therefore, in the rear part of the roof opening, the canvas is sucked upward, which makes it difficult to open and close the canvas. there were.

The problem that a negative pressure part is generated in the rear part of the roof opening is to provide a deflector further rearward so as to spread the region where the wind flow is disturbed on the roof surface to the rear part of the roof opening. However, if the deflector is installed further rearward, the deflector will be located above the roof opening, and thus the roof opening can be set to a large size. However, there is a problem in that the feeling of opening is impaired, and it was the current situation that the deflector had to be provided at the front edge of the roof opening.

Purpose of the Invention The present invention does not impair the feeling of opening on the roof during normal traveling, that is, when the canvas suction force is small and the canvas opening / closing operability does not occur, and the roof is not damaged during high-speed traveling. It is an object of the present invention to provide a vehicle canvas top structure in which the upper negative pressure generation region can be significantly reduced and the opening and closing operability of the canvas is improved.

Configuration of the Invention The purpose of the present invention is to provide the front edge of the roof opening of the vehicle with
This is achieved by providing a deflector that extends in the vehicle body width direction and is movable rearward along the vehicle body front-rear direction by the traveling wind pressure when the traveling wind pressure is equal to or higher than a predetermined value.

According to the present invention, the deflector is located at the front edge of the roof opening of the vehicle during normal running when the wind pressure of the wind blowing on the deflector is less than the predetermined value, so that the feeling of opening on the roof is impaired. When the vehicle is running at high speed and the running wind pressure is above a certain level, the deflector moves rearward along the longitudinal direction of the vehicle body, so the negative pressure area generated at the roof opening is minimized during high-speed running. It is possible to improve the opening and closing operability of the canvas.

In a preferred embodiment of the invention, the deflector is
It is provided at the front edge of the roof opening of the vehicle through a spring and other elastic members. In this way, by providing the deflector via the elastic member, it is possible to move the deflector rearward along the longitudinal direction of the vehicle body in accordance with the traveling wind pressure during high-speed traveling when the traveling wind pressure exceeds a predetermined value. It is possible with a simple structure.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a canvas top structure according to an embodiment of the present invention. FIG. 1 (a) is a schematic perspective view of a deflector, and FIG. 1 (b) is a mounting base for mounting the deflector on a vehicle body. FIG. 1 (c) is a schematic perspective view showing the front side of the roof opening of the vehicle body.

As shown in FIG. 1 (a), the deflector 1 has slopes 2 and 2 that gradually rise rearward, and a vehicle body width direction central portion 3 thereof is attached to a vehicle body after mounting.
It is composed of almost horizontal surfaces. By having such a shape, the deflector 1 bounces up the wind blown on the vehicle body during traveling, and disturbs the flow of the air behind the deflector 1, so that the roof opening 5 of the vehicle body 4 is prevented.
Moreover, the negative pressure portion is prevented from being generated. Sliders 8 that can be fitted to the rail portions 7 of the mounting base 6 are provided at the lower ends of both edge portions of the deflector 1, respectively. A spring 9 is attached to the front side of the slider 8.

As shown in FIG. 1 (b), the mounting base 6 has rail portions 7 on both sides thereof that extend in the vehicle front-rear direction and in which the slider 8 of the deflector 1 is fitted. The other end of the spring 9 attached to the front side of the slider 8 is attached to the front inner surface of the rail portion 7 of the attachment base 6, and biases the deflector 1 to the front side. The mounting base 6 is provided with a plurality of mounting portions 10, and as shown in FIG. 1 (c), the roof panel 11 of the vehicle body 4 has bolts at positions corresponding to these mounting portions 10. A hole 12 is provided, and a nut (not shown) is welded to the roof panel 11 on the back surface of the bolt hole 12, so that the mounting base 6 is fixed to the roof panel 11 of the vehicle body 4 by a bolt. There is. Although not shown, the canvas is configured to be pulled by a cable and move along guide rails provided on both side edges of the roof panel 11 to open and close the roof opening 5.

In the vehicle canvas top structure according to the embodiment of the present invention configured as described above, since the deflector 1 is constantly urged to the front side by the spring 9,
During normal traveling in which the wind pressure of the wind blowing on the front surface of the deflector 1 is not so large, the deflector 1 is located at the front edge of the roof opening 5 of the vehicle body 4 and blocks the front portion of the roof opening 5 of the vehicle body 4. It doesn't hurt the sense of openness. On the other hand, as the vehicle speed increases, the wind pressure of the wind blown on the front surface of the deflector 1 gradually increases, and when the wind pressure overcomes the spring force of the spring 9, the deflector 1 moves backward along the longitudinal direction of the vehicle body 4. Therefore, the region where the wind flow on the roof surface is disturbed by the deflector 1 spreads to the rear portion of the vehicle body 4, and as a result, the negative pressure region generated on the roof surface can be minimized. Therefore, it is possible to easily open and close the roof opening 5 by operating the canvas even when traveling at high speed.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the scope of claims for utility model registration, and these are also included in the scope of the invention. Needless to say.

For example, in the above-described embodiment, the deflector 1 is mounted on the vehicle body 4 via the mounting base 6. However, the roof panel 11 of the vehicle body 4 is provided with a rail portion to which the slider 8 can be fitted. May be directly attached to the roof panel 11 of the vehicle body 4.

Effect of the Invention According to the present invention, it is possible to significantly reduce the upward suction of the canvas at high speeds without impairing the feeling of opening on the roof during normal driving, and to improve the operability of opening and closing the canvas. It is possible to obtain the canvas top structure of the vehicle.
