Description

[Detailed Description of the Invention] Industrial Application Field The present invention provides a window section provided on the roof of an automobile that
The present invention relates to a sunroof opening/closing device that can be opened and closed by a sunroof panel divided into two parts.

BACKGROUND ART This type of automobile sunroof opening/closing device includes a lid for opening and closing the front part of the sunroof window;
A sunroof panel is composed of a lid that opens and closes the rear part of the vehicle, and the front lid is opened and closed by moving the rear part of the vehicle up and down, and the rear lid is opened and closed by sliding in the longitudinal direction of the vehicle. It's getting old. For example, this sunroof opening/closing device was proposed in a patent application filed in 1983 by the present applicant.
There is a device generally filed as No. 181366, in which a series of opening and closing operations of the front lid and the rear lid are performed by a single wire drive. That is, by pulling and driving the wire from the closed state of the front and rear lids, the rear end of the front lid is first rotated upward and opened, and then the rear end of the rear lid is lowered. At the same time, it can be opened by being slid toward the rear of the vehicle and stored within the roof panel.

Incidentally, as shown in FIG. 23, the opening of the front lid is carried out by a lifting mechanism 3 having a link 2 which is raised by driving the wire 1. That is, this elevating mechanism 3 is
A pin 6 protrudes from a slider 5 that slides on the guide rail 4 by a wire 1, and this pin 6 is engaged with one end of the link 2. By pulling the wire 1 toward the rear of the vehicle (to the right in the figure), the pin 6 is pulled together with the slider 5.
moves in the same direction, and the pin 6 pushes up the cam-shaped protrusion 6a of the link 2, causing the link 2 to stand up as shown in FIG. Then, the front lid (not shown) attached to the other end of the link 2 is rotated upward using its front end as a fulcrum and opened. By the way, when this link 2 stands up,
A claw piece 7a at the tip of the detent lever 7 engages with one end of the link 2, so that the link 2 is maintained in an upright state. Further, after the link 2 is erected, the pin 6 moves further rearward together with the wire 1 to open the rear lid, but at this time the pin 6 is separated from the lever 7. Then, when the front lid is closed, the wire 1 moves to the front of the vehicle (to the left in the figure) and depresses the detent lever 7 to release the engagement with the link 2. It is designed to lie down.

Problems to be Solved by the Invention However, in such a conventional sunroof opening/closing device, when the link 2 is folded down, that is, when the front lid is closed, the pin 6 engages with the root portion of the cam-shaped projection 6a. The link 2 is kept in a laid-down state by only being moved. However, since the pin 6 is only attached to the wire 1, if a load is applied to the pin 6 in the longitudinal direction of the vehicle, some movement is allowed. That is, when the front lid tries to swing up and down due to road vibration, etc., this swinging force moves the pin 6 in the longitudinal direction of the vehicle through the link 2, causing the front lid to swing and flap. This will cause the seal between the front lid and the roof to deteriorate.

Furthermore, in such a conventional sunroof opening/closing device, in order to push up the front lid by the moving force of the pin 6, that is, the driving force of the wire 1, the distance from the rotation center P of the link 2 to the acting force of the pin 6 is It is necessary to increase the standing moment of the link 2 by increasing the distance to some extent. For this reason, the distance between the rotation center P of the link 2 and the pin 6 inevitably becomes longer, resulting in an increase in the size of the elevating mechanism 3, and the roof becomes thicker in order to accommodate this elevating mechanism 3. There was a problem that the interior space became small.

Therefore, the present invention reduces the standing load of the link by moving the center of rotation of the link,
Opening/closing of an automobile sunroof that allows the elevating mechanism to be made more compact and also prevents the front lid from flapping by holding the link in the collapsed state with a groove provided on the guide rail side. The purpose is to provide equipment.

Means for Solving the Problems In order to achieve the above object, the present invention provides a tilt lid that is opened and closed via a front elevating mechanism, and a tilt lid that is opened and closed via a front elevating mechanism is provided at the front part of a window formed on the roof of an automobile. A slide lid is movably attached to the rear portion of the vehicle at the rear of the window via a rear slider driven by a wire to a main guide rail mounted on the left-right side of the vehicle, and is opened and closed by the movement of the slider. A rear lifting mechanism is provided between the slide lid and the rear slider to raise and lower the rear part of the slide lid in conjunction with the movement of the rear slider, and a wire for driving the slider and the front lifting mechanism are provided. In between, there is provided an attachment/detachment mechanism that is detached after the front lifting mechanism completes the lifting operation and is connected when the front lifting mechanism starts lowering. In the automobile sunroof opening/closing device that has come to be used, the front elevating mechanism includes a sub-guide rail mounted on the roof side and a front slider movably attached to the sub-guide rail via the attaching/detaching mechanism. , a first link is rotatably attached between the front slider and the tilt lid, and the tilt lid is operated to open and close as the angle changes as the front slider moves, and the guide member is protruded from the first link. and forming a guide groove for guiding the guide member on the sub-guide rail side,
The curved surface of the guide groove is configured to accurately match the movement locus of the guide member.

Function With the above-described structure, in the opening/closing device for an automobile sunroof of the present invention, when the window portion is opened, the wire is driven in the pulling direction, and the front lifting mechanism is first activated. In operation of this front elevating mechanism, a front slider interlocked with a wire via an attachment/detachment mechanism moves on a sub-guide rail, thereby erecting the first link. The first link is erected using a pivot point attached to the front slider as a fulcrum, and this fulcrum is moved along with the front slider. The arm of the upright moment that acts at this time is determined by the length of the first link itself, and a large moment can be obtained and the driving force of the wire can be significantly reduced.
There is no need to extend the link downward from its pivot point, that is, the fulcrum, and the front elevating mechanism can be made smaller. Furthermore, when the first link falls down, the movement locus of the guide member protruding from the first link is made to precisely match the curved surface of the guide groove provided on the sub-guide rail side, so that the guide member Since the first link is closely fitted into the groove, the first link is restricted by the guide groove and is prevented from rotating. Therefore, the tilt lid in the closed state does not swing up and down due to road vibrations, etc., and the sealing performance between the tilt lid and the roof is ensured.

Next, after the first link of the front elevating mechanism is erected, the attachment/detachment mechanism is removed, leaving the front elevating mechanism and the wire further moves on the guide rail together with the rear slider. Then, the rear elevating mechanism is activated by moving the rear slider to lower the rear part of the slide lid, and the slide lid is moved and stored within the roof panel. At this point, the sunroof is fully open.

Next, when the sunroof is closed, the wire is moved in the opposite direction, so that the slide lid and tilt lid are closed by an operation opposite to that when the sunroof is opened.

By the way, in this embodiment, the first link 32 of the front elevating mechanism 20 is provided with a roller 40 as a guide member, and the sub-guide rail 3 is provided with a roller 40 as a guide member.
Since the guide groove 42 into which the roller 40 is fitted almost closely is provided on the zero side, the roller 40 is locked in the guide groove 30 when the tilt lid 13 is closed, and the swinging of the first link 32 is prevented. Prevented. Therefore, when the tilt lid 13 is closed, it will not flap due to road vibrations etc. during driving.
Sealing performance is ensured to prevent rainwater from entering the vehicle interior. Further, the front elevating mechanism 20 includes a first link 32 that is rotatable between the front slider 31 that slides on the sub-guide rail 30 and the tilt lid 13 that is rotated about the rotation shaft 21. The first link 32 is raised and lowered, that is, the tilt lid 13 is opened and closed by the movement of the front slider 31. Therefore, the first link 32
The upright moment is determined by the length of the first link 32, and this length can be directly used as the length of the arm of the moment, so the first link 32 can be shortened. Therefore, the front elevating mechanism 20 can be made smaller.

Effects of the Invention As explained above, in the automobile sunroof opening/closing device of the present invention, the opening/closing operation of the tilt lid and slide lid, which are divided into two parts, is performed by a common wire drive. , the first link of the front elevating mechanism for opening and closing the tilt lid is fitted and locked in a guide groove provided in the sub-guide rail via a guide member when the tilt lid is closed, and the curved surface of the guide groove is connected to the guide groove. Since the first link is made to precisely match the movement locus of the member, swinging of the first link is completely prevented. Therefore, even if the tilt lid in the closed state is subjected to a load in the opening direction due to vibrations during running or wind pressure, the first link attached to the tilt lid is prevented from swinging. Movement of the tilt lid in the opening direction is prevented. This eliminates the flapping of the tilt lid, significantly improving the sealing performance and preventing rainwater from entering the vehicle interior, and also prevents the generation of banging noises when the lid flaps, greatly improving the quietness of the vehicle interior. be able to. Furthermore,
The front elevating mechanism is configured by rotatably providing a first link between a front slider and a tilt lid that move on a sub-guide rail, and the first link is raised or lowered by movement of the front slider. Because it has become like this,
The upright moment acting on the first link when the tilt lid is opened can be established depending on the length of the first link. Therefore, the first link only needs to be set to a length necessary for opening the tilt lid, and the front elevating mechanism can be miniaturized and the roof thickness can be reduced, which is an excellent effect.
