Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile roof structure, and more particularly to an open top type automobile roof structure capable of attaching and detaching a vehicle body roof.

(Prior Art) As a roof structure of an automobile of this type, as shown in, for example, British Patent Publication No. 2086316, a substantially inverted U-shaped foldable pillar is provided between both side walls of a vehicle body. It is known that a roof panel is detachably laid between the top portion of the fallen pillar and the top portion of the windshield. In this structure, the collapsible pillar is centered on both leg ends,
It is rotatable from an upright position to a tilted position where it is housed in the vehicle compartment behind the seat, and a hood is generally stretched between the retractable pillar and the vehicle compartment rear portion. When the retractable pillar is stood upright, the rear side of the cabin from the retractable pillar is covered with a hood, and in this state, the roof panel is hung between the retractable pillar and the windshield to form the vehicle body roof. can do.

(Problems to be Solved by the Invention) In such a structure, in order to remove the vehicle body roof to make it an open type, first remove the roof panel and store it in a predetermined storage place, and then move the retractable pillar to the tilted position. It requires a complicated two-step procedure in which the removal work cannot be carried out quickly. This also applies to the work for mounting the vehicle body roof.

Further, in the conventional roof structure, the vehicle compartment behind the collapsible pillar is covered with the hood as described above, so that the appearance is not so good, and the hood is struck by wind when traveling at high speed. There were problems such as vibration and noise.

Therefore, the present invention provides a roof structure for an automobile, which can improve the operability of the above-mentioned mounting and dismounting work, and can also solve the problems of the appearance and the above-mentioned noise during high-speed traveling. It is intended.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a roof structure of an automobile having a roof that extends rearward from a front header of an upper portion of a front windshield of the automobile and covers a vehicle compartment, wherein the roof is It is divided into a roof front part that is formed of a hard member and covers the front part of the passenger compartment and a roof rear part that covers the rear part of the passenger compartment. The roof front part and the roof rear part respectively extend downward at both ends in the vehicle width direction. The roof front part and the roof rear part are provided with a closed position that covers the passenger compartment and at least a part of them are overlapped and housed in the storage part below the belt line at the rear part of the car body. The vehicle body side mounting part of the roof front part is pivotally attached to the vehicle body side wall below the belt line so that the roof front part can be moved back and forth. In addition, the vehicle body side attachment portion of the roof rear portion is pivotally attached to the vehicle body side wall below the belt line behind the vehicle body side attachment portion of the roof front portion.

(Effects of the Invention) In the present invention thus configured, since the roof front portion and the roof rear portion that constitute the roof formed of the hard member are pivotally attached to the vehicle body through the vehicle body side attachment portions, respectively. By simply pivoting the roof front portion and the roof rear portion, one of the roof forming position, that is, the closed position and the storage position, that is, the open position can be set. Therefore, unlike the conventional case where the roof panel has to be completely separated from the vehicle body for storage, the roof installation or storage work can be performed in a short time by a simple operation. Further, in the present invention, since the entire roof is formed of the hard member as described above, the appearance is desired, and vibration noise does not occur even when receiving wind. Furthermore, since the roof front and the roof rear are at least partially overlapped with each other and are located at the open position when they are stored, the storage space can be made relatively small.

(Embodiment) Hereinafter, a roof structure of 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 a vehicle body of the automobile, and reference numeral 2 indicates a front header 4 above a front window 3 to a rear body 5. The roof extends rearward and covers the passenger compartment 6. The roof 2 is formed of a hard member made of a steel plate or the like, and has a roof front portion 7 that covers the vehicle interior front portion 6a and a roof rear portion 8 that covers the vehicle interior rear portion 6b.
It is divided into two parts in the longitudinal direction of the vehicle. The roof rear portion 8 includes a rear window 9.

The roof front portion 7 is provided with a vehicle-body-side mounting portion (hereinafter, simply referred to as mounting portion) 10 having a substantially inverted U shape as a whole, and lower end portions 11a of both leg portions 11 of the mounting portion 10 are It extends below the belt line 12 of the vehicle body 1 and slightly obliquely forward. As shown in FIG. 6, the both leg portions 11 are pivoted 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 at the lower end portion 11a. It is pivotally attached by a wearing pin 15. In addition, this mounting part 1
0 may omit the part which extends across the roof 2 and may be constituted only by the leg portions 11.

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

The roof front portion 7 and the roof rear portion 8 constituting the roof 2 are rotated about 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. At this open position, the roof front part 7 and the roof rear part 8 are housed in a housing part at the rear part of the vehicle compartment in a state of being overlapped with each other in the front-rear direction. The roof front portion 7 and the roof rear portion 8 are shown by solid lines in FIG. 3 between the closed position and the open position, as will be described later in detail.
Rotate as indicated by the one-dot chain line and the two-dot chain line.

The roof front portion 7 and the roof rear portion 8 can be operated between the closed position and the open position by the drive mechanism 20 shown in FIG. The drive mechanism 20 includes a drive gear 21.
Are driven to rotate by an electric motor 23 via a double worm mechanism 22. When the roof 2 is in the closed position shown in FIG. 1, a drive arm 24 extending obliquely forward and upward from the drive gear 21 is fixed to the drive gear 21 at its lower end. Lower end portion 1 of mounting portion 10
A pivot pin 11c is also provided at a position above the pivot pin 15 of the connecting arm 11b fixed to 1a and extending upward. A first link 26 is attached to the pivot pin 11c at its upper end, and the lower end of the first link 26 is pivotally attached to the upper end of the drive arm 24 by a pivot pin 25. On the other hand, a pivot pin 27 is provided at a position rearward of the pivot pin 17 of the mounting portion 16 for the roof rear portion 8. A second link 28 is attached to the pivot pin 27.
Is pivoted at its upper end and this second link 2
Similarly to the first link 26, the lower end 8 is pivotally attached 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 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 11b is the inner panel 13.
Extends across. In addition, in FIG. 6 and FIG. 7, reference symbol G indicates a windshield.

In the closed position of the roof 2, the first link 26 is
As shown in detail in FIG. 5, it extends substantially in line with the drive arm 24 and at a slight angle with respect to the leg 11. Therefore, even if the motor 23 is driven and the drive arm 24 rotates in the direction of arrow A so as to open the roof 2, the drive arm 24 moves the first arm 26 through the first link 26 at the beginning of this rotation. The operation of the legs 11 is extremely small. Therefore, the operation of the roof front portion 7 is small at the initial stage of this rotation. On the other hand, the second link 28 is arranged so as to extend in a direction substantially perpendicular to the drive arm 24 at the roof closed position. Therefore, when the motor 23 is driven as described above, the arrow of the drive arm 24 is provided. At the initial stage of the rotation in the A direction, the mounting portion 16 is rotated relatively largely around the pivot pin 17. Therefore, the roof rear portion 8 is largely operated in the initial stage of the above rotation. In this way, at the beginning of the opening operation of the roof 2, the roof rear portion 8 starts to operate quickly and largely, and the roof front portion 7 operates to continue small, so that the opening operation of the roof can be performed smoothly. .

On the other hand, as shown in FIG. 8, the second link 28 extends at a slight angle with respect to the drive arm 24 in the open position of the roof 2. Therefore, the motor 23 is driven and the drive arm 24 closes the roof 2 by the arrow B.
Even if the mounting portion 16 is rotated in the direction, the actuation of the mounting portion 16 via the second link 28 by the drive arm 24 becomes small in the initial stage of this rotation. Therefore, the operation of the roof rear portion 8 is small at the initial stage of this rotation. On the other hand, the first link 2
6 is the drive arm 24 in this roof open position.
It is arranged so as to extend in a direction substantially perpendicular to, and therefore, when the motor 23 is driven as described above, it largely operates at the initial stage of the rotation of the drive arm 24 in the direction of the arrow B. Therefore, the roof front part 7 is largely operated in the initial stage of the above rotation. As described above, in the closing operation of the roof 2, the roof front part 7 starts to operate quickly and largely, the roof rear part 8 starts to operate smaller to follow, and the roof front part 7 is completely positioned at the closed position. After that, since the roof rear portion 8 is rotated to the closed position, the closing operation of the roof can be smoothly performed.

The operations of the roof front portion 7 and the roof rear portion 8 described above are shown in FIGS. 3 and 4. In these figures, the state in which the roof front portion 7 opens is F-closed, F-1, F-
2, F-3, F-open, and the state in which the roof rear portion 8 opens is shown by R-closed, R-1, R-2, R-3, R-opened.

When the roof 2 is stored in the rear part of the vehicle compartment, that is, in the back part of the rear seat 30, the seat back 3 of the rear seat 30 is stored.
