Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides an opening formed in the roof of an automobile.
This invention relates to a sunroof device that has a light-transmitting lid and a non-light-transmitting sunshade and can be opened and closed in a double manner.

(Prior Art) In this type of sunroof device, it is difficult to simply tilt up the translucent lid.
Simply lifting the rear part of the lid and tilting it upwards does not immediately ventilate the interior of the car, and there is also the inconvenience of having to open the sunshade.

Therefore, in conventional sunroof devices of this kind, for example, as disclosed in Japanese Utility Model Application Publication No. 60-132919, a ventilation opening with a louver is provided in the sunshade and the lid is simply tilted up.
Some are designed to ventilate the inside of the car through the ventilation openings, while others have sunshades that open slightly towards the rear in conjunction with the lid's tilt-up.

(Problem to be Solved by the Invention) In the above-mentioned conventional device in which the sunshade is provided with a ventilation port, even when the lid is closed, the sunshade ventilation port is always open, so the heating inside the car is heated through this ventilation port. The hot air from the air conditioner and the cold air from the air conditioner escape into the roof, causing drafts, or even if there are louvers, undesirable light from outside the car may shine into the car depending on its direction, causing damage to the ceiling inside the car. Furthermore, when the sunshade is closed, the ventilation opening is always exposed to the inside of the car, which poses problems such as unfavorable aesthetics of the inside of the car.

In addition, in conventional devices in which the sunshade opens slightly rearward in conjunction with the lid's tilt up, the part where the lid opens (rear part) and the part where the sunshade opens (front part) are shifted back and forth. There is a problem in that a long passage for air to flow is formed between the lid and the sunshade, resulting in poor ventilation.

An object of the present invention is to provide a sunroof device that solves all of the above-mentioned problems.

(Means for Solving the Problems) In order to achieve the above object, the sunroof device of the present invention has an opening formed in the roof of an automobile with a light-transmitting lid and a non-light-transmitting sunshade. , the lid can be opened and closed doubly, and a sliding member moves backward and forward along a guide rail provided on the side edge of the opening, thereby moving the lid to a fully closed position where the opening is closed. In a sunroof device, the sunroof device is provided with a drive device on the roof for moving the roof rearward and upward to a tilted position, wherein the sunroof is configured with at least two unit sunshades divided into front and rear parts. and at least the rear unit sunshade is mounted so as to be movable along a guide rail substantially parallel to the moving direction of the sliding member,
The rear unit sunshield is provided with an engaging portion, and the sliding member is provided with an engaged portion that engages with the engaging portion and opens the rear unit sunshade forward when the sliding member moves forward. It is characterized by the fact that it has been established.

(Function) In the sunroof device of the present invention, when the translucent lid is chilled up by the drive device, the unit sunshade at the rear opens in conjunction with this. Air permeability can be improved compared to other devices.

In addition, to close the rear unit sunshade,
The lid may close automatically in conjunction with the operation of the drive device when returning the lid from the tilted position to the fully closed position, but after the lid is closed to the fully closed position,
The rear unit sunshade may be closed by manual operation from inside the vehicle.

When the lid is in the fully closed position, the unit sunshades can be freely opened and closed, either individually or as a unit, to allow daylight into the vehicle interior.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

FIGS. 1a to 1d are schematic longitudinal sectional side views for explaining the principle and operation of an embodiment of the present invention.

In these figures, 1 is the roof of the car;
a is the exterior plate of roof 1, 1b is the interior plate, and 2
3 is an opening having a substantially rectangular planar shape (see Fig. 2), which is bored through both the exterior plate 1a and the interior plate 1b of the roof 1, and 3 is a translucent opening made of glass or acrylic plate. This lid is made of material and is used to open and close the upper part of the opening 2.

The first lid 3 is driven by a drive device A, which will be described later.
As shown in figure a, there is a fully closed position where the upper part of the opening 2 is completely closed, and as shown in figure 1b, there is a tilted position where the rear part is slightly raised from the fully closed position and the entire body is tilted rearward and upward. As shown in FIG. 1c, the rear part is slightly lowered from the fully closed position to the lowered position, and as shown in FIG.
and the interior panel 1b, and can be moved to a fully open position where the opening 2 is opened to the maximum.

The vertical distance between the exterior plate 1a and interior plate 1b of the roof 1 at the front of the opening 2, and the distance between the front of the lid 3 and the lower edge of the opening 2 when fully closed are as follows:
Since the vertical distance between the exterior plate 1a and the interior plate 1b of the roof 1 at the rear of the opening 2 is smaller than the vertical distance between the exterior plate 1a and the interior plate 1b of the roof 1, the rear part of the lid 3 is lowered slightly from the fully closed position and moved backward, thereby opening the lid 3. The whole can be almost completely accommodated within the roof 1 behind the opening 2.

Reference numeral 4 denotes a sunshade made of a non-translucent synthetic resin that opens and closes the lower part of the opening 2; It has a front and rear two-part structure consisting of a rear unit sunshade (hereinafter referred to as rear sunshade) 6 for closing the rear half of the sunshade.

The front sunshade 5 includes a pair of guide rails 7 (see FIG. 2 and subsequent figures) fixed to the interior panel 1b of the roof 1 on both sides of the opening 2 and facing in the front-rear direction.
The rear sunshade 6 is mounted so as to be slidable along the front sunshade 5, and the rear sunshield 6 is mounted so as to be slidable in the front-rear direction so as to overlap vertically.

A pair of left and right engagement pieces 8 (only one of which is shown), which are engagement parts, are provided on the upper surface of the front end of the rear sunshade 6 and have their tips bent toward the rear. A horizontal pin 9 forming an engaged portion of the drive device A can be engaged with and detached from the engagement piece 8 from the rear.

When the lid 3 is moved from the fully closed position to the tilt position by the drive device A, this pin 9 advances from the position shown in FIG. 1a to the position shown in FIG. to move the rear sunshade 6 from the fully open position shown in FIG. 1a.
It is adapted to be opened to the fully open position shown in Figure 1b.

Reference numeral 10 denotes a handle provided on the rear lower surface of the rear sunshade 6 and used when opening and closing the rear sunshade 6 from inside the vehicle.

On the upper surface of the front end of the front sunshade 5, there are
A pair of engagement pins 11 (only one of which is shown) is provided in a protruding manner.
2 (only one of which is shown) can be engaged from the front.

When the lid 3 is opened from the lowered position to the fully open position, each hanging piece 12 engages with the engagement pin 11, and the front sunshade 5 is opened from the lower position to the fully open position.
It can be opened from the fully closed position shown in Figure 1c to the fully open position shown in Figure 1d.

At this time, the rear sunshade 6 moves backward together with the front sunshade 5.

Reference numeral 13 denotes a handle provided on the lower front surface of the front sunshade 5 and used when opening and closing the front sunshade 5 from inside the vehicle.

Thus, in this embodiment, when the lid 3 moves from the fully closed position to the tilt position, the rear sunshade 6 automatically opens forward in conjunction with it, and the lid 3 moves from the lowered position to the fully open position. When the front sunshade 5 is opened to the maximum, the engaging pin 11 of the front sunshade 5 engages with the hanging piece 12 of the lid 3 and is pushed backward, so that the front sunshade 5 automatically opens toward the rear. At this time, the rear sunshade 6 is automatically opened rearward together with the front sunshade 5 due to the frictional resistance with the front sunshade 5, and the other front sunshade 5 and the rear sunshade 5 are opened rearward. 6 is opened and closed by manual operation from inside the vehicle.

FIGS. 3 to 6 are diagrams showing in detail a more specific embodiment of the above-described embodiment.

In these figures, each of the above-mentioned members is given the same reference numeral as above, and a detailed explanation thereof will be omitted, and the following explanation will focus exclusively on the structure and operation of the drive device A. .

Incidentally, most of the drive device A is almost the same as disclosed in the specification and drawings of, for example, Japanese Utility Model Application No. 60-51671.

Further, the present invention is not characterized by the configuration of the drive device A itself, but any device that can open the above-mentioned rear sunshade 6 in conjunction with the tilt-up operation of the lid 3. Of course, a drive device having a similar configuration may also be used.

In this embodiment, each guide rail 7 of the drive device A includes three sliding members 14, 15 at the front, middle, and rear portions that are slidably fitted together independently of each other. It is equipped with 16.

On the front sliding member 14, a bracket 17 supporting each side of the lid 3 is attached to a shaft 1 facing in the left-right direction.
It is pivoted with 8.

In the sliding member 15 in the middle part, a roller 20 that is configured to roll along a cam groove 19 of a desired shape formed in the bracket 17 is attached to a shaft 21 facing in the left-right direction.
This sliding member 15 is pivotally connected with
From the state shown in FIG. 3, by moving forward relative to the front sliding member 15, the bracket 17 and the lid 3 are moved as shown in FIG. The sliding member 15 can be moved to the tilt position shown in FIG.
By retreating relative to the front sliding member 15 from the state shown in the figure, the bracket 17 and the lid 3 are moved as shown in FIG. It can be moved to the lowered position.

In this embodiment, the pin 9 is provided protrudingly on the inner surface of the sliding member 15 in the middle portion, and when the sliding member 15 moves forward during the above-mentioned tilt-up operation, the pin 9 is inserted through the engaging piece 8. , the rear sunshade 6 can be opened to the fully open position.

The hanging piece 12 is provided on the lower surface of the front end of the lid 3, corresponding to that shown in FIGS. 1a to 1d, but it may be provided on the front sliding member 14 as the case may be.

The rear sliding member 16 is connected to the rear part of the bracket 17 by a connecting rod 22.

23 is a shaft 2 that is attached to the sliding member 16 and faces in the left-right direction.
4, and the front end of the lock lever is provided with a hook 23a that can be engaged with and detached from the front end of a rearward-facing projecting piece 25 fixed to the upper surface of the rear end of the sliding member 16 in the middle part. Further, a downward protrusion 23b that can be engaged with and disengaged from an engagement hole 26 bored at a key point in the bottom wall portion of the guide rail 7 is provided at the rear end.

The lock lever 23 is always biased by an appropriate spring (not shown) in the direction in which the protrusion 23b engages with the engagement hole 26, that is, in the clockwise direction in FIGS. As shown in FIG. 2, when the sliding member 15 at the middle portion approaches the sliding member 16 and the protruding piece 25 enters below the lock lever 23,
The lock lever 23 is rotated counterclockwise in FIGS. 3 to 5 against the biasing force of the spring, and the protrusion 23b comes out of the engagement hole 26.
In addition, the hook 23a is adapted to engage with the front end of the protruding piece 25.

The configuration of the sliding members 14, 15, 16, etc. described above is as follows:
They are provided on each of the left and right guide rails 7 so as to be symmetrical to each other.

Cables 27 (see FIG. 6), which can be moved back and forth in synchronization with each other by an appropriate motor (not shown), are slidably inserted into each guide rail 7, and one end of each cable 27 is inserted into the guide rail 7. , is fixed to the sliding member 15 at the middle portion.

The front and rear sliding members 14, 16 are not connected to a cable 27, but are connected to the middle sliding member 15 via a bracket 17, a connecting rod 22, etc.

Since the drive device A is configured as described above, it operates as follows.

As shown in FIG. 3, when the lid 3 is in the fully closed position, the protrusion 23b of the lock lever 23 is inserted into the engagement hole 2.
6, the sliding member 16 is locked to the guide rail 7, and the sliding member 14 is connected to the sliding member 16 with a bracket 17 and a connecting rod 22.
forward movement is prevented by being connected to.

From this state, when the motor is activated to move the cable 27 forward, only the sliding member 15 moves forward, and the lid 3 moves forward due to the relationship between the roller 20 and the cam groove 19, as shown in FIG. While being moved to the tilt position, the rear sunshade 6 is opened forward by the pin 9.

When the cable 27 is pulled rearward from the tilted state shown in FIG. 4 and the sliding member 15 is returned to the position shown in FIG. 3, the lid 3 is returned to the fully closed position in the opposite manner to that described above.

At this time, the pin 9 moves backward together with the sliding member 15 and separates from the engagement piece 8, leaving the rear sunshade 6 in the fully open position.

When the cable 27 is pulled rearward and the sliding member 15 is moved slightly backward from the fully closed state shown in FIG.
is moved to the lowered position, and at about the same time,
The protruding piece 25 enters below the lock lever 23,
The lock lever 23 is rotated counterclockwise as shown in FIG.

When the cable 27 is pulled further rearward from this state, the three sliding parts 14, 15, 16, the bracket 17, the lid 3, etc. are integrated and moved rearward while remaining in the state shown in FIG. At the same time, the hanging piece 12 engages with the engagement pin 11, so that the front sunshade 5 and the rear sunshade 6 are simultaneously moved rearward.

When the lid 3 etc. reach the fully open position as shown in FIG. 1d, the operation of the motor is stopped by a suitable limit switch (not shown) or the like.

When the cable 27 is advanced from the fully open position, the sliding member 15 is advanced, and
Since the hook 23a is engaged with the front end of the protruding piece 25, the sliding member 16 and the sliding member 1
The sliding member 14 connected to the connecting rod 6 through the connecting rod 22 and the bracket 17 is respectively moved forward.

At this time, the lid 3 also moves forward together with the bracket 17, etc., and the hanging piece 1 provided on the lid 3 moves forward.
2 is separated from the engagement pin 11, and the front sunshade 5 and rear sunshade 6 are left open.

When the sliding member 16 reaches the position shown in FIG.
The protrusion 23b of the lock lever 23 enters the engagement hole 26, the sliding member 16 is locked to the guide rail 7, and the hook 23a is released from the front end of the protruding piece 25, so that only the sliding member 15 moves further. As a result, the lid 3 is returned from the lowered position to the fully closed position.

(Modification) FIGS. 7 and 8 show a modification of the means for attaching the rear sunshade to the front sunshade.

In this example, a guide groove 30 for guiding the pin 29 protruding from the side surface of the rear sunshade 6 is provided on the inner surface of the side frame 28 that supports the front sunshade 5, and a guide groove 30 is provided in the middle and rear part of the guide groove 30. By providing the stepped portion 30a that slopes toward the front and upper side, when the rear sunshade 6 is opened forward, the rear sunshade 6 overlaps above the sunshade 5, and when the rear sunshade 6 is closed, the rear sunshade 6 overlaps with the sunshade 5. The lower surface of the sunshade 6 is located on the same plane as the lower surface of the front sunshade 5, so that the appearance of the interior of the vehicle can be improved.

Note that the same members as those in the above-mentioned embodiment are given the same reference numerals, and the description thereof will be omitted.

In addition, in the present invention, for example, the sunshade is divided into three parts in the front and back direction, and the rear part is opened in conjunction with the lid's tilt-up operation, or the lid can be opened and closed even when the lid is not tilt-up. Many modifications can be made to the operation, such as interlocking the opening and closing of the unit sun shade.

(Effects of the Invention) According to the present invention, the following effects can be achieved.

(a) When the lid is in the fully closed position, each unit sunshade can be opened and closed freely to allow daylight into the vehicle interior.

(b) When the lid is moved to the tilt position by the drive device, the rear unit sunshade is automatically opened forward by the sliding member, so there is no need to manually open the sunshade when tilting up, making it convenient. In addition, when the lid is closed, hot or cold air inside the car can be dissipated through the ventilation opening, causing drafts, and the light shielding properties may be impaired. It is possible to eliminate the risk of damage to the interior of the vehicle or damage to the aesthetics of the interior of the vehicle.

(c) The part where the lid opens when the lid is tilted up and the part on the sunshade side that opens in conjunction with it are both at the rear of the opening, so there is good ventilation between the inside and outside of the car. Therefore, unlike conventional devices in which the front of the sunshade opens slightly in conjunction with the lid's tilt-up, a long air passage is formed between the lid and the sunshade, impairing ventilation. There's no fear.
