Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automobile roof structure, and more particularly to an open-top automobile roof structure in which the roof of the vehicle body can be attached and removed.

(Prior Art) As disclosed in British Patent Publication No. 2086316, for example, the roof structure of this type of automobile has a generally inverted U-shaped collapsible pillar that spans between both side walls of the vehicle body. It is known that a roof panel is removably stretched between the top of the tilting pillar and the top of the windshield. In this structure, the collapsible pillar can rotate around its both leg ends from an upright position to a tilted position where it is stored in the passenger compartment behind the seat. A canopy is generally placed between the chamber and the rear part. When the collapsible pillar is placed in the upright position, the rear side of the vehicle interior from the collapsible pillar is covered by the hood, and in this state, the roof panel is stretched between the collapsible pillar and the windshield to form the vehicle roof. can do.

(Problem to be solved by the invention) In such a structure, in order to remove the roof of the car body and make it an open type, first remove the roof panel and store it in a designated storage location, and then move the collapsible pillars to the tilted position. This required a cumbersome two-step procedure in which the device had to be brought down, making it impossible to perform the removal process quickly. This also applies to the installation work of the vehicle roof.

In addition, with conventional roof structures, as mentioned above, the cabin behind the folding pillars is covered with a hood, which does not look very good, and the hood is easily blown by the wind when driving at high speeds. There were problems such as vibration and noise.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an automobile roof structure that can improve the operability of the above-mentioned installation and removal work, and also solve problems such as appearance problems and the above-mentioned noise during high-speed driving. That is.

(Means for Solving the Problems) The automobile roof structure of the present invention is a roof that extends rearward from the front header above the front window of the automobile and covers the passenger compartment, and the roof is formed of a hard member and It is divided into a roof front part that covers the front part of the passenger compartment and a roof rear part that covers the rear part of the passenger compartment. A closed position in which a side attachment part is provided and the roof front part and the roof rear part cover the passenger compartment, and an open position in which the vehicle is at least partially overlapped and stored in a storage part at the rear of the passenger compartment so that the vehicle is in an open state. The vehicle body side mounting portions of the roof front portion and the roof rear portion are pivotally connected to the vehicle body so that the roof front portion and the roof rear portion can be moved between It is characterized by being connected to.

(Effects of the Invention) In the present invention configured as described above, the roof front part and the roof rear part constituting the roof made of hard members are each pivotally attached to the vehicle body via the vehicle body side attachment part. By simply pivoting, the roof front part and the roof rear part can be placed in either the roof forming position, that is, the closed position, or the stowed position, that is, the open position. Therefore, unlike the conventional case where the roof panel must be completely separated from the vehicle body for storage, the roof can be installed or stored in a short time with simple operations. Further, in the present invention, since the entire roof is formed of a hard member as described above, the roof has a desirable appearance and does not generate vibration noise even when exposed to wind. Furthermore, when the vehicle is stored, the front roof and the rear roof are at least partially overlapped in the open position, so the storage space can be made relatively small. Furthermore, the structure is simple because the roof front part and the roof rear part can be driven by a single driving means.

(Embodiments) Hereinafter, a roof structure for an automobile according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a side view of a roof structure of an automobile according to an embodiment of the present invention, and in this figure, reference numeral 1
2 indicates the body of the automobile, and 2 indicates the area from the front header 4 at the top of the front window 3 to the rear podium 5.
This is a roof that extends rearward to cover the vehicle interior 6. The roof 2 is made of a hard member such as a steel plate, and includes a roof front part 7 that covers the front part 6a of the vehicle interior, and a rear roof part 8 that covers the rear part 6b of the vehicle interior.

The above-mentioned coupe front portion 7 is provided with a vehicle body side attachment portion (hereinafter abbreviated as “attachment portion”) 10 having an approximately inverted U-shape as a whole.
The lower end portions 11a of both leg portions 11 extend downward and forward from the pelt line 12 of the vehicle body 1 at a slight angle. As shown in FIG. 6, the leg portions 11 are pivoted at the lower end portion 11a to the front edge 13a located inside the rear edge 14a of the side door 14 of the inner panel 13 inside the rear fender F. It is pivotally connected by a mounting pin 15. Incidentally, the mounting portion 10 may omit the portion extending across the roof 2 and may simply be composed of only the leg portions 11.

On the other hand, at lower end portions on both sides of the roof rear portion 8, vehicle body side attachment portions (hereinafter simply referred to as attachment portions) 16 are provided that extend forward and below the belt line 12. This mounting portion 16 has a pivot pin 17 of the inner panel 13 at its tip 16a.
It is pivoted by.

The roof front part 7 and the roof rear part 8, which constitute the roof 2, rotate around the pivot pins 15 and 17, so that they can take the closed position shown in FIG. 1 and the open position shown in FIG. It's getting old. In this open position, the roof front section 7 and the roof rear section 8 are stored in a storage section at the rear of the vehicle interior in a state where they are stacked one on top of the other. The roof front part 7 and the roof rear part 8 are rotated between the closed position and the open position as shown by the solid line, one-dot chain line, and two-dot chain line in FIG. 3, as will be explained in detail later. move.

The roof front part 7 and the roof rear part 8 are
A drive mechanism 20 shown in FIG. 5 allows operation between the closed and open positions. The drive mechanism 20 includes a drive gear 21, and the drive gear 21 is rotatably driven by an electric motor 23 via a double worm mechanism 22. The drive gear 21 includes a drive arm 2 that extends diagonally forward and upward from the drive gear 21 when the roof 2 is in the closed position shown in FIG.
4 is fixed at its lower end. Mounting part 1
A pivot pin 11c is also provided at a position above the pivot pin 15 of the connecting arm 11b which is fixed to the lower end portion 11a of 0 and extends upward. This pivot pin 1
1c, a first link 26 is bonded at its upper end, and the lower end of this first link 26 is pivotally connected to the upper end of the drive arm 24 by a pivot pin 25. On the other hand, the above-mentioned attachment part 1 for the roof rear part 8
A pivot pin 27 is provided at a position rearward of the pivot pin 17 of No. 6. A second link 28 is pivotally connected to this pivot pin 27 at its upper end, and like the first link 26, this second link 28 is pivoted to the upper end of the drive arm 24 at its lower end by a pivot pin 25. has been done.

Therefore, the roof rear portion 8 operates to a large extent at the initial stage of the rotation. In this way, at the beginning of the opening operation of the roof 2, the roof rear part 8 starts to move quickly and greatly, and the roof front part 7 follows this and moves small, so that the roof opening operation can be performed smoothly. .

On the other hand, as shown in FIG.
In the open position of the roof 2, the drive arm 2
It extends at a slight angle to 4. Therefore, even if the motor 23 is driven and the drive arm 24 rotates in the direction of the arrow B to close the roof 2, at the beginning of this rotation, the drive arm 24 is connected to the second link 28 by the drive arm 24. The operation of the mounting portion 16 is reduced. Therefore, at the beginning of this rotation, the movement of the roof rear portion 8 is also small. On the other hand, the first link 26 is arranged to extend substantially perpendicularly to the drive arm 24 in the roof open position, and therefore, when the motor 23 is driven as described above, the drive arm 24 It operates largely at the beginning of rotation in the direction of arrow B. Therefore, the roof front portion 7 operates largely at the beginning of the rotation. In this way, in the closing operation of the roof 2, the roof front part 7 starts to move quickly and greatly, and the roof rear part 8 starts to move small following this, and the roof front part 7
After the roof rear part 8 is completely positioned in the closed position, the roof rear part 8 is rotated to the closed position, so that the roof can be smoothly closed.

The operations of the roof front section 7 and the roof rear section 8 described above are shown in FIGS. 3 and 4. In these figures, the state in which the roof front part 7 is opening is indicated by F-closed, F-1, F-2, F-3, F-open, and the state in which the roof rear part 8 is opening is indicated by R-closed.
It is shown as R-1, R-2, R-3, and R-open.
