Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a sunroof device for a vehicle, which is provided with an opening/closing body that can open and close the roof opening by either tilting or sliding.

"Prior Art" As a conventional sunroof device for a vehicle, there is one disclosed in, for example, Japanese Utility Model Application Publication No. 164820/1983.

That is, in this publication, a plurality of shoes movable along a rail are provided, and a link mechanism that stands on the shoes allows the opening/closing body to be opened and closed by either tilting or sliding.

What moves the opening/closing body during tilting is substantially one link member that rises and falls.

``Problem that the invention seeks to solve'' However, in such conventional sunroof devices, the amount of opening and closing of the opening/closing body is equal to the lifting height of the link member that raises and lowers, and in order to obtain a sufficient lifting height, the link mechanism occupies The increased thickness of the sunroof increases the overall thickness of the sunroof, which takes up space and lowers the ceiling of the vehicle interior, impairing the comfort of the vehicle interior and increasing the height of the vehicle.

The present invention has been made in view of these conventional problems, and aims to provide a sunroof device for a vehicle that is thin as a whole and requires a thin and small installation space.

``Means for Solving the Problems'' The gist of the present invention to achieve this purpose is to provide a roof opening provided in a vehicle with an opening/closing body that can be opened and closed by either tilting or sliding. A sunroof device for a vehicle, which includes rails arranged along both sides of the roof opening, a base base that pivotally supports the proximal end of the opening and closing body, and a drive that is driven vertically in response to opening and closing of the opening and closing body. A base and a braking base disposed at a position corresponding to the free end of the opening/closing body are slidably fitted to the side edge of the rail, and the braking base and the free end of the opening/closing body are connected to the arm. A tilting member is connected to the base base and the drive base by a member, and is erected to swing as the drive base moves, and a tip of the tilting member is connected to an intermediate portion of the arm member. Features include a sunroof device for a vehicle.

"Operation" When the opening/closing body tilts to open/close, move the drive base at the set position.

Due to the movement of the drive base, the raising/lowering member rotates in the upright direction when opening, and rotates in the falling direction when closing.

The free end of the raising/lowering member displaces the intermediate portion of the arm member, and the arm member is raised/lowered relative to the stationary brake base, whereby the opening/closing body is tilted to open/close.

When the opening/closing body slides open, the tilting member is completely pushed down until the free end of the opening/closing body is located below the rear edge of the roof opening, and the drive base is moved further from that position. rides on each base and moves along the side edge of the rail to leave from under the roof opening, and the roof opening opens. When closing, the operation is the opposite.

The connecting member 45 is pivotally supported by the brake shoe 40 via a pivot pin 45a so as to be swingable in a seesaw motion.

At the front end of the connecting member 45 facing the drive shoe 50, an engagement groove 46 is formed that can be engaged with and detached from the engagement pin 51 at the rear end of the drive shoe 50. Although not shown in the drawings, the rear end of the connecting member 45 is formed with a brake engaging portion that can be engaged with and detached from a notch carved in the rail 14, and a biasing spring causes the brake engaging portion to engage with the notch. It is biased in the direction of insertion.

The engagement groove 46 of the connecting member 45 has an entry opening that opens toward the engagement pin 51 of the drive shoe 50, a push-down inclined portion on the lower surface of the rear end, and a locking jaw that is constricted upward at the rear end.

The drive shoe 50 is formed with an upward vertical groove 50a into which a plate-shaped raising/lowering member 41 is fitted, and a cam groove 52 that rises and falls depending on the front and back position is formed over almost the entire length of the drive shoe 50. The raising/lowering member 41 is inserted into the vertical groove of the drive shoe 50, and its cam follower 44 is fitted into the cam groove 52.

The cam groove 52 includes a fully open guide portion 52a, an open/close guide portion 52b, a fully close guide portion 52c, and a retractable guide portion 52d.

A shade plate 60 capable of shielding a ceiling opening 16 on the inside of the vehicle interior that overlaps with the roof opening 11 is disposed below the opening/closing body 20.

The shade plate 60 is formed by a main shade plate 60a and a sub shade plate 60b that opens and closes an opening provided in the main shade plate 60a.The base end of the sub shade plate 60b is pivoted to the main shade plate 60a by a hinge 61. It is worn.

Both ends of the main shade plate 60a are slidably fitted to the rails 14, so that the shade plate 60 as a whole slides or tilts to follow the opening/closing body 20.

Mounting brackets 63 are fixed to both sides of the front end of the main shade plate 60a.

Pull up lever 28
is biased slightly clockwise in FIG. 1 by a spring 29.

Next, the action will be explained.

FIG. 1 shows a state in which the opening/closing body 20 is tilted and fully opened, the drive shoe 50 is closest to the base shoe 30, and the cam follower 44 of the raising/lowering member 41 is in the fully open guide portion 52a of the cam groove 52 of the drive shoe 50. It is located and stopped.

The brake engaging portion of the connecting member 45 engages with a notch in the rail 14 of the roof opening 11 to restrict movement of the brake shoe 40, and the raising/lowering member 41 engages with a notch in the rail 14 of the roof opening 11.
By suppressing the rising and falling of the opening/closing body 6, the opening degree of the opening/closing body 20 is regulated and restrained from sliding. The free end of the opening/closing body 20 is reliably supported by an arm member 26.

The shade plate 60 is pulled up when the pull-up lever 28 provided on the opening/closing body 20 is restricted from rotating by the stopper end 28a, and the engagement pin 28b of the engagement end 28c engages with the hook bracket 67, thereby raising the sub-shade plate 60b. is tilted and opened together with the opening/closing body 20.

When the electric motor 12a of the drive unit 12 is activated and the geared cable 13 is moved vertically by the drive gear 12b, the drive shoe 50 fixed to the geared cable 13 is driven to move rightward in FIG. The cam follower 44 of the raising/lowering member 41 moves from the fully open guide portion 52a of the cam groove 52 of the drive shoe 50 to the opening/closing guide portion 52b, and the raising/lowering member 41 falls down according to the inclination of the opening/closing guide portion 52b.

A slight displacement of the pivot pin 43 at the tip of the tilting member 41 causes the arm member 26 to tilt at a large angle, and the opening/closing body 20 and the lid plate 21 are moved to the pivot 20a of the base shoe 30.
The door closes by tilting around the center.

As shown in FIG. 7, when the cam follower 44 of the raising/lowering member 41 reaches the fully closed guide portion 52c at the rear of the cam groove 52 of the drive shoe 50, the sealing member 23 comes into close contact with the sealing surface 15 of the roof opening 11 to open and close it. body 20
tilts and closes completely.

When the opening/closing body 20 closes, the pull lever 28
is lowered, the subshade plate 60b also lowers, closing the opening of the main shade plate 60a. When the opening/closing body 20 is fully opened, the presser bracket 68 enters the presser piece 53 of the drive shoe 50 and the subshade plate 60
Even if I press b from below, it won't open.

When the drive shoe 50 is moved to the left in FIG. 7 from the state where the opening/closing body 20 is tilted and fully closed, the opening/closing body 20 and the cover plate 21 are tilted and fully opened in the opposite operation to the above. I can do it.

When opening, the arm member 26 operates to pull up the free end of the opening/closing body 20, so the base end side of the opening/closing body 20 is not pressed against the sealing surface 15, resulting in less fatigue of the sealing member 23 and good durability. At the same time, waterproofness is also improved.

When the drive shoe 50 is further moved to the right from the completely closed state, as shown in FIG.
The cam follower 44 of No. 1 moves within the recessed guide portion 52d of the cam groove 52 of the drive shoe 50, and the raising/lowering member 4
1 further falls down, and the rear end of the cover plate 21 and the seal member 23 retract inward from the rear roof 10 and are held on the seal member 18b of the gutter 18.

The cam follower 44 of the raising/lowering member 41 is in the cam groove 52
When the drive shoe 50 moves until it reaches the rear end of the retractable guide portion 52d, the engagement pin 51 engages the connecting member 45.
The connecting member 45 enters the engagement groove 46 from the entry opening, pushes down the push-down slope, and reverses the connecting member 45 in a seesaw motion against the urging force of the urging spring.

When the distal end of the connecting member 45 is lowered, the brake engaging portion rises and disengages from the notch of the rail 14, releasing the restricted state. The engagement pin 51 of the drive shoe 50 engages with the locking jaw of the engagement groove 46, and the brake shoe 40 becomes movable rearward.

When the drive shoe 50 is moved rearward, the brake shoe 40 is pushed by the drive shoe 50 and slides rearward, the opening/closing body 20 is stored under the roof 10, and the front part of the roof opening 11 is opened.

When the drive shoe 50 is returned from the open state and the opening/closing body 20 is closed, the braking engagement portion rides on the surface of the rail 14, so the connecting member 45 cannot be reversed and the engagement of the drive shoe 50 is interrupted. Matching pin 5
1 hooks the locking jaws of the engagement groove 46 of the connecting member 45 and pulls the brake shoe 40 forward.

In this manner, the opening/closing body 20 slides and opens/closes due to the movement of the brake shoe 40. As the opening/closing body 20 slides, the shade plate 60 also moves.

When the fully closed state is reached, the braking engagement portion of the connecting member 45 falls into the notch of the rail 14 of the roof opening 11 and engages with it, and the forward movement of the opening/closing body 20 is restricted, and then the opening/closing body 20 is fully closed.

"Effect of the invention" According to the vehicle sunroof device according to the invention,
Since the opening/closing body is tilted and opened/closed by the combination of the tilting member and arm member that stand on each base, the opening/closing body can be tilted greatly with a small lift of the tilting member, and only a small lift is required. The opening/closing body and the attached mechanism can be made thinner, allowing the vehicle to be lowered and ensuring sufficient head clearance.

Since the free end of the opening/closing body is supported with high rigidity by the arm member, the opening/closing body will not wobble even when traveling in the tilted open state.

Furthermore, since the base of the opening/closing body takes a desirable trajectory, the durability of the sealing member is improved and the waterproofness is improved.
