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 that allows the roof of the vehicle body to be attached and removed.

(Prior Art) As disclosed in British Patent Publication No. 2,086,316, for example, the roof structure of this type of automobile has a generally inverted U-shaped collapsible pillar that is hung between both side walls of the vehicle body. It is known that a roof panel is removably hung between the top of the collapsible pillar and the top of the windshield. In this structure, the collapsible pillar is centered around its both leg ends,
It is rotatable between an upright position and a tilted position where it is stored in the passenger compartment behind the seat, and a canopy is generally provided between the collapsible pillar and the rear part of the passenger compartment. 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 hung between the collapsible pillar and the windshield to close the vehicle roof. (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. Thereafter, the collapsible pillar must be tilted to the tilted position, which is a cumbersome two-step procedure, and therefore the removal operation cannot be carried out 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, the present invention aims 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. r It shall be white.

(Means for solving the problem) White of the present invention! 1! The roof structure of the JJ car is a roof that extends rearward from the upper part of the front window of the car and covers the passenger compartment.The roof is made of a hard material and covers the front part of the passenger compartment. The roof front part and the roof rear part cover the rear part of the vehicle compartment. is provided, and when the roof front section and the roof rear section are in the closed position l covering the vehicle interior, the automobile is in an oven state. The vehicle body side attachment portions of the roof front portion and the roof rear portion are pivoted to the vehicle body so that the roof front portion and the roof rear portion are movable between an open position in which the roof front portion and the roof rear portion are at least partially overlapped and stored in a storage portion at the rear of the vehicle interior. The vehicle body side mounting portions are each connected to one driving means via a link mechanism.

(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. As a result, the roof front part and the roof rear part can be placed either in the roof forming position, that is, the closed position, or in the stowed position, that is, the open position, by simply pivoting the roof front part and the roof rear part. 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. In this figure, reference numeral 1 indicates the automobile body, and reference numeral 2 indicates a section extending from the front header 4 above the front window 3 to the rear body 5. This is a roof that extends rearward to cover the vehicle interior 6. This roof 2 is formed of a hard member made of a steel plate or the like, and includes a roof front part 7 that covers the front part 6a of the passenger compartment, and a roof rear part 8 that covers the rear part i6b of the passenger compartment.
It is divided into two parts in the front and rear direction of the vehicle. Conventionally, the roof rear portion 8 includes a rear window 9.

The above-mentioned coupe front part 7 is provided with a vehicle body side mounting part (hereinafter referred to as the mounting part) 10 which has an approximately inverted U-shape as a whole, and the lower ends 11a of both legs 11 of this mounting part 10 are It extends slightly diagonally downward and forward from the belt line 12 of the vehicle body 1. As shown in FIG. 6, the legs 11 are located at the lower end 11a behind the side door 14 of the inner panel 13 inside the rear fender F. 14a, and is pivotally connected to the front edge 13a located inwardly by a pivot 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, the lower end portions of both sides of the roof rear portion 8 are provided with vehicle body side mounting portions (
A mounting section 16 (hereinafter simply referred to as a mounting section) is provided. This attachment part 16 is attached to the inner panel 1 at its tip 16a.
It is pivotally connected by the pivot pin 17 of No. 3.

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 has become. 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 indicated by solid lines in FIG.
It rotates as shown by the one-dot chain line and the two-dot chain line.

The roof front part 7 and the roof rear part 8 can be operated between the closed position and the open position by a drive mechanism 20 shown in FIG. This drive mechanism 20 includes a drive gear 21, and this drive gear 21
Is the electric motor connected through the double worm mechanism 22? It is designed to be rotationally driven by 3. A drive arm 24 is fixed to the drive gear 21 at its lower end, and extends diagonally forward and upward from the drive gear 21 when the roof 2 is in the closed position shown in FIG. Installation 8'! .

A pivot pin II is also provided at a position above the pivot pin 15 of the connecting arm Ilb fixed to the lower end portion 11a of 10 and extending upward.
C is provided. A first link 26 is bonded to the pivot pin 11C at its upper end.
The lower end of the link 26 is connected to the upper end of the drive arm 24 by a pivot pin 2.
It is pivoted at 5. On the other hand, a pivot pin 27 is provided at a position rearward of the pivot pin 17 of the attachment portion 16 for the roof rear portion 8 . This pivot pin 27 has
A second link 28 is pivotally connected at its upper end, and like the first link 26, this second link 28 is pivotally connected at its lower end to the upper end of the drive arm 24 by a pivot pin 25.

As shown in FIGS. 6 and 7, the mounting portion 16, the first and second links 26, 28 and the drive arm 24
etc. are arranged between the rear fender F and the inner panel 13, the mounting portion 10 is arranged inside the inner panel 13, and the connecting arm 1.1b extends across the inner panel 13. Note that in FIGS. 6 and 7, the symbol G indicates a window glass.

When the roof 2 is in the closed position, the first link 26 is
As shown in detail in FIG. 5, it extends generally in line with the drive arm 24 and at a slight angle to the leg 11. Therefore, even if the motor 23 is driven and the drive arm 24 rotates in the direction of arrow A to open the roof 2, at the beginning of this rotation, the drive arm 24 The actuation of the leg 11 becomes extremely small. Therefore, at the beginning of this rotation, the operation of the roof front section 7 is also small. On the other hand, the second link 28 is arranged to extend substantially perpendicularly to the drive arm 24 in this roof closed position, so that when the motor 23 is driven as described above, the drive arm 24 is At the beginning of the rotation in the A direction, the mounting part 1
6 is rotated relatively largely around the pivot pin 17.

Therefore, the roof rear portion 8 operates largely at the beginning 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. 8, the second link 26 extends at a slight angle with respect to the drive arm 24 when the roof 2 is in the open position. 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 does not move through the second link 28. The operation of the mounting portion 16 is reduced. Therefore, at the beginning of this rotation, the operation of the roof rear portion 8 is also small. On the other hand, the first link 26 is connected to the drive arm 2 in this roof open position.
It is arranged so as to extend in a direction substantially perpendicular to 4,
Therefore, when the motor 23 is driven as described above, it operates largely at the beginning of the rotation of the drive arm 24 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 begins to move quickly and greatly, and the roof rear part 8 follows this and starts to move slightly, until the roof front part 7 is positioned at the completely closed position. After that, the roof rear portion 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 states in which the roof front part 7 is opening are F-closed, F-1, and I-.
2, F-3, and F-open, and the state in which the roof rear portion 8 is opening is shown as R-closed, R-1, R-2, R-3, and R-open.

Note that when storing the roof 2 in the rear part of the vehicle interior, that is, the back of the rear seat 30,
1 is designed to be tilted forward as shown by the two-dot chain line in FIG.
