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. 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. It can be done.

(Problem to be solved by the invention) In such a structure, in order to remove the car body roof and make it into an oven type, first remove the roof panel and store it in a designated storage location, then move the collapsible pillar to the tilted position. This required a cumbersome two-step procedure in which the device had to be brought down, making it impossible to quickly perform the removal operation. 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. This is the purpose.

(Means for Solving the Problems) The automobile roof structure of the present invention is white! JJ tun no fu I'j
A roof that extends rearward from the front rudder at the top of the window and covers the entire passenger compartment, the roof being formed of a hard member, and the roof extending below the belt line at both ends in the width direction of the vehicle. a closed position in which the roof covers the passenger compartment; and a cover in which the roof is at least partially overlapped and stored in a storage area at the rear of the rear seat so that the roof is in an oven state. The vehicle body side mounting portion of the roof is pivotally attached to the vehicle body so that the roof can be moved between This detection means is characterized in that a control means is connected to the control means that allows the ruler to open and close only when an output signal is received from the detection means.

(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, in the present invention, the roof is actuated after detecting the forward inclination of the seat back of the rear seat, so that the seat does not interfere with the movement of opening and closing the roof by pivoting the front and rear of the roof. do not have.

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. The 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 vehicle interior, and a roof rear part 13 that covers the rear seat 6b of the vehicle interior.
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 roof front section 7 is provided with a vehicle body side mounting section (hereinafter referred to as "mounting section") 10 which has an approximately inverted U-shape as a whole. It extends slightly diagonally downward and forward from the belt line 12 of No. 1. As shown in FIG. 6, the leg portions 11 are pivoted at the lower end portion 11a to the front aR 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 pin 15. In addition, this mounting part 1
0 may omit the portion that extends across the roof 2 and may simply consist of only the leg portions 11.

On the other hand, at the lower end portions of both sides of the roof rear 88, 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 rotatably driven by an electric motor 23 via a double worm mechanism 22. 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. Lower end 11 of mounting part 10
A pivot pin llc is also provided at a position above the pivot pin 15 of the connecting arm llb fixed to 1a and extending upward. A first link 26 is bonded to the upper end of the pivot pin 11C, 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 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 this second link 2
Similarly to the first link 26, the lower end of the link 8 is pivotally connected 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 part 10 is arranged inside the inner panel 13, and the connecting arm llb is arranged between the inner panel 13.
extends across the 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 leg 811 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, the motor 23 is driven so that the drive arm 24 closes the roof 2 as indicated by the arrow B.
Even if the mounting portion 16 is rotated in the direction, the movement of the mounting portion 16 by the drive arm 24 via the second link 28 is small at the beginning of this rotation. 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 2
6 is the drive arm 24 in this roof open position.
Therefore, when the motor 23 is driven as described above, it operates largely at the beginning of rotation of the drive arm 24 in the direction of the arrow B. Therefore, the roof front portion 7 operates largely at the beginning of the rotation. In this way, to the roof 2
At A, the roof front part 7 begins to move quickly and greatly, followed by the roof rear part 8, which starts to move slightly, and after the roof front part 7 is completely positioned at the closed position, Since the roof rear portion 8 rotates to the closed position, 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 section 7 is open and goes "C" is referred to as F-closed, F-1, and F-1.
-2, I-3, and F-open, and the state where the roof rear portion 8 is opening is shown as R-closed, R-1, R-2, R-3, and R-open.

With only the structure explained above, when the roof front part 7 and the roof rear part 8 of the roof 2 are stored in the storage part on the back of the rear seat 30, or when pulled out from the storage part, the seat back 31 of the rear seat 30 is There is a possibility that the movement of the front part 7 and the roof rear part 8 may be interfered with.

Therefore, in the present invention, a forward tilt switch 40 is provided to detect forward tilting of the seat back 31 of the rear seat 30 prior to the opening/closing movement of the roof 2, and an output signal from the forward tilt switch 40 is provided. A control circuit 41 is provided which activates the motor 23 for actuation of the roof 2 when received.

The forward tilt switch 40 is supported on the support bracket 42 of the seat cushion 30a of the rear seat 30, as shown in FIG. When the seat back 31 is tilted forward, it is closed by the lower end of the support bracket 43 of the seat back 31. A manual operation switch 44 that allows the operator to instruct the operator to open and close the roof 2 is connected to the control circuit 41. However, when the signal from the switch 40 is not input to the control circuit 41, the operation switch 44
The motor 23 is not driven even if the signal from the control circuit 41 is inputted to the control circuit 41. FIG. 12 shows an example in which the control circuit 41 and the like are constructed from electric circuits.
