Description

Description: TECHNICAL FIELD The present invention relates to a sunroof device for vehicles such as automobiles.

(Prior Art) As a sunroof apparatus in which an opening 2 formed in a roof 1 of a vehicle, for example, a vehicle such as a passenger car, is opened and closed by a panel 3, there is a conventional sunroof apparatus as shown in FIG. That is, in FIG. 19, 4 is a guide rail arranged on both sides of the opening 2 and has a notch 5. Reference numeral 6 denotes a lifter mounted on both sides of the lower surface of the panel 3, the front end of which is pivotally connected to a shoe 7 in the guide rail 4. The lifter 6 has a cam groove 8 and an engagement projection 9. Reference numeral 10 denotes a slider that can slide along the guide rail 4 and a lifter 6.
And a pin 11 to be inserted into the cam groove 8. A timing arm 12 is connected to the shoe 7 and has an engaging portion 13 that engages with the notch 5 of the guide rail 4. Also,
A cam groove 14 is formed in the timing arm 12, and a pin 15 that engages with the cam groove 14 is provided on the slider 10. Reference numeral 16 denotes a closing arm, which is supported and guided by the guide rail 4 via a guide portion 17. This deadline arm 16
Is an engaging portion 17a that engages with the engaging protrusion 9 of the lifter 6,
The slider 10 has an engaging portion 19 that engages with the engaging protrusion 18, and is urged rearward by a spring 20.

In the sunroof device, when the panel 3 is tilted up from the fully closed state in FIG. 19 as shown in FIG.
The slider 10 is moved backward by the drive cable.
Then, since the pin 11 slides along the cam groove 8, the panel 3 rises around the shoe 7 and tilts up as shown in FIG. At this time, the pin 15 is
The engagement portion 13 is disengaged from the cutout 5 of the guide rail 4 to slide inside the rear end 14. Subsequently, when the slider 10 is moved backward, the pin 15 and the timing arm 12
Since the shoe 7 moves rearward, the panel 3 moves rearward to the fully open position as shown in FIG. 21 while maintaining the tilt-up posture.

(Problems to be Solved by the Invention) The conventional sunroof device of this type has the following problems.

First, since the lifting mechanism constituted by the slider 10 and the cam groove 8 is located at the front of the panel 3, the tilt opening / closing force is weak. For this reason, tilt opening / closing cannot be performed mainly due to resistance generated by friction between the weather strip at the peripheral portion of the panel 3 and the wall surface of the roof 1 and negative pressure generated during high-speed running, and the panel 3 is not closed even when fully closed. The trailing edge of the is floating.

Therefore, high-speed vehicles require high-torque motors and high-strength parts, which increase the size of the parts, resulting in dimensional loss, high prices, and the use of high-torque motors. There is a problem that the friction of the sliding part increases and the durability of the sliding part deteriorates.

In this case, considering only the tilt opening / closing force, the opening / closing mechanism such as the slider 10 and the cam groove 8 is preferably located as close to the rear end of the panel 3 as possible. However, the further this shifts, the greater the tilt opening / closing force becomes, but the smaller the opening amount A when the panel 3 is fully opened, and the larger the drop B of the cam groove 8 in order to secure a constant tilt amount. Must be done, which also affects the overall thickness.

Second, the effect of the closing arm 16 is limited to about 180 km / h. That is, in order to increase the tilt opening / closing force and to prevent the rear end of the panel from floating when fully closed due to negative pressure, most spoiler-type sunroof devices are provided with a hook-type closing arm 16. I have.

However, in order to reach the thickness, the hooking allowance C cannot be designed with a margin, so that the upward acting force F
Is too large, a phenomenon occurs that the closing arm 16 is not hooked.

Third, since the panel 3 is supported by the pins 11 of the slider 10 at the time of tilting and at the time of moving back and forth, the supporting position is the same. In the slide sunroof device, the largest force is required immediately before fully opening and closing, particularly when the tilt is lowered, just before full closing. However, when moving the panel 3 back and forth, it is sufficient that the panel 3 has a supporting point at a position where the panel 3 has sufficient force to move the panel 3 back and forth, and the vertical play of the panel 3 does not significantly occur.

Therefore, considering only the time of the forward and backward movement, the panel 3
The point of support may be earlier. If the support point is closer to the front, the rear end of the cam groove 8 is closer to the front, so that the opening amount A can be increased by that dimension. If the tilt amount is the same, the drop of the cam groove 8 Since B can be reduced, the overall thickness can be reduced.

However, it is difficult to move the supporting point of the panel 3 forward in order to secure the necessary force at the time of opening and closing the tilt. There are various problems that the support positions are the same.

The present invention has been made in view of such a conventional technique, and has an object to provide a sunroof device capable of increasing a tilt opening / closing force, being excellent in high-speed responsiveness, further improving opening efficiency, and reducing the overall thickness. It is assumed that.

(Means for Solving the Problems) According to the present invention, an opening 22 is formed in a roof 21 and guide rails 25 are fixed to the left and right of the opening 22, and a front and rear of a slider 27 supported and guided by the guide rail 25 is provided. By the movement, the panel 23 closing the opening 22 is tilted open and closed around the pivot shaft 37 between the fully closed position X and the tilted up position Y, and is tilted up between the tilted up position Y and the fully opened position Z. In a sunroof device that is moved back and forth as it is, an elevating member 30 that elevates and lowers the panel 23 with respect to the guide rail 25 is provided on the rear end side of the opening 22, and the slider 27 is used only when the panel 23 is tilted. A timing arm 29 for operating the lifting member 30 in conjunction with the slider 27 is provided.
Further, there is provided a support portion 44 for supporting the panel 23 in the tilted-up state while maintaining the height with respect to the roof 21 when moving back and forth between the tilted-up position Y and the fully opened position Z.

(Operation) The panel 23 is moved from the fully closed position X to the fully open position Z,
To open the opening 22, the slider 27 is moved rearward along the guide rail 25. Then, the elevating member 30 operates in conjunction with the slider 27 via the timing arm 29, so that the elevating member 30 pushes up the rear end side of the panel 23, and the panel 23 is tilted up to the tilt-up position Y around the pivot shaft 37. Tilt up to When the panel 23 rises to the tilt-up position Y, the support portion 44 of the slider 27 supports the panel 23 in a tilt-up state. Therefore, the panel 23 moves rearward in that state.

When closing, the slider 27 may be moved forward.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, although an Example illustrates the spoiler type sunroof apparatus, it is not limited to this.

Are provided with a cam groove 43 and a pin 44 for a supporting portion, respectively. The guide shafts 40 and 41 are movably fitted in a pair of guide portions 32 and 33 of the guide rail 25 via rollers 45, 46 and 47 so as to be movable in the front-rear direction, and the cable connecting portion 42 is a cable of the guide rail 25. It is connected to the drive cable 48 in the guide section 34.

Accordingly, the slider 27 is movable back and forth along the guide rail 25 by the driving force of the driving cable 48.
The pin 44 is movably fitted into the cam groove 39 of the lifter 26 via the roller 49, and when the slider 27 moves rearward and the pin 44 reaches the rear end of the cam groove 39, FIG. The panel 23 is held at the tilt-up position Y as shown in FIG.

The front timing arm 28 is disposed between the lifter 26 and the slider 27 in the front-rear direction as shown in FIGS. The front timing arm 28 is provided with a long hole 50 in the front-rear direction at the front end, and a rearwardly rising cam groove 51, an engaging portion 52, and a pin 53 at the rear side.

The pin 53 is slidably fitted into the cam groove 43 of the slider 27. When the panel 23 is at the tilt-up position Y, the cam action between the pin 23 and the cam groove 43 is caused by the forward and backward movement of the slider 27. The engaging portion 52 of the front timing arm 28 is
To be disengaged.

The lifting link 30 is disposed on the rear end side of the opening 22 as shown in FIGS.
A mount 55 fixed to the base 31 is pivotally supported via a fixed shaft 56 so as to be vertically swingable. The elevating link 30 is provided with a pin 57 at the tip and a tilt cam groove 58 near the fixed shaft 56, respectively. The pin 57 is fitted to the guide portion 40 of the lifter 26 via a roller 59 so as to be movable back and forth. Tilt cam groove
58 is used to fix the lifting link 30 to the fixed shaft 56 when the panel 23 is tilted.
The tilt cam groove 58 is formed so as to open backward at the base.

The rear timing arm 29 is for swinging the elevating link 30 in conjunction with the forward / backward movement of the slider 27, and is provided in the arm guide portion 35 of the guide rail 25 as shown in FIGS. It is slidably inserted in the front-rear direction. After this, the timing arm 29 has an engaging portion 60 at the front end.
However, a pin 61 is provided at each rear end, and a cam groove 62 in the front-rear direction is formed between the two.

The engaging portion 60 is detachably engageable with the notch 63 of the guide rail 25, and the pin 61 is slidably fitted into the tilt cam groove 58 so as to swing the elevating link 30 by moving the rear timing arm 29 back and forth. It is rare. The guide shaft 41 of the slider 27 is slidably inserted into the cam groove 62, and the front end of the cam groove 62 is engaged with the engaging portion 60 by the forward and backward movement of the guide shaft 41.
Are bent downward so as to engage and disengage with the notch 63 of the guide rail 25.

Next, the operation will be described with reference to the operation explanatory diagrams of FIG. 9 to FIG. In FIGS. 9 to 11, the rear timing arm 29 is shifted downward for easy understanding.

FIG. 9 shows a fully closed state in which the panel 23 is at the fully closed position X. At this time, the slider 27 is at the front end position, and the pin 53 of the front timing arm 28 is engaged with the rear end of the cam groove 43. . Since the guide shaft 41 is engaged with the front end of the cam groove 62 of the rear timing arm 29,
Is disengaged forward from the notch 63 of the guide rail 25.

Therefore, when the slider 27 is driven rearward by the drive cable 48 and the slider 27 is moved rearward along the guide rail 25, the guide shaft 41 is engaged with the bent portion at the front end of the cam groove 62. The rear timing arm 29 slides backward in the arm guide portion 35 of the guide rail 25 in conjunction with the movement of the slider 27.

Then, since the pin 61 moves backward while sliding in the tilt cam groove 58, the elevating link 30 rotates clockwise around the fixed shaft 56 by the cam action of the pin 61 and the tilt cam groove 58, and Push the end up.

Therefore, the panel 23 is tilted up around the pivot shaft 37 to the tilt-up position Y in FIG.

In this case, since the lifting link 30 is pushed up on the rear end side of the panel 23, a sufficient tilt opening / closing force can be exerted, and the tilt-up operation is ensured, and the tilt-up during high-speed traveling becomes possible. High-speed support is improved. In addition, a low-torque motor can be used as the drive source motor, and the whole can be reduced in size and cost.

On the other hand, when the panel 23 is tilted up, the pin 38 is guided in a rearwardly upward shape by the cam groove 51 of the front timing arm 28, so that the pivot shaft 37 moves slightly backward in the elongated hole 50.

Therefore, even if the panel 23 is tilted up around the pivot shaft 37, the weather strip 24 at the front end of the panel 23 is
It does not come into strong contact with the wall surface of 21, and its damage can be prevented.

When the panel 23 rises to the tilt-up position Y, the pin 44 of the slider 27 is located at the rear end side of the cam groove 39 of the lifter 26, and the pin 23 and the pivot shaft 37 move the panel 23 through the lifter 26. Support in tilt-up state.

That is, during the tilt-up, the pin 61 of the rear timing arm 29 slides in the tilt cam groove 58 and pushes up while supporting the rear end of the panel 23 by the lifting link 30.
When the pin 61 is lifted to the tilt-up position Y in FIG. 10, the pin 61 is disengaged from the tilt cam groove 58, and the support by the elevating link 30 is released.
The panel 23 is supported by the pins 44.

On the other hand, the pin 53 of the front timing arm 28
The front timing arm 28 rises to reach the upper bent portion of the front end of the cam groove 43, and the engaging portion 52 is disengaged from the notch 54 of the guide rail 25.

Further, since the guide shaft 41 of the slider 27 is disengaged rearward from the lower bent portion of the front end of the cam groove 62 of the rear timing arm 29, the rear timing arm 29 is lowered, and the engaging portion 60 is engaged with the notch 63 of the guide rail 25. Combine. As a result, the rear timing arm 29 is restricted from moving backward, and even if the slider 27 moves backward, the guide shaft 41 only moves in the cam groove 62, and the rear timing arm 29 does not move.

Therefore, when the slider 27 is further moved rearward after the panel 23 has been moved up to the tilt-up position Y, the front timing arm 28 moves rearward integrally with the slider 27.

At this time, the panel 23 is moved rearward via the pin 38 engaging with the cam groove 51 of the front timing arm 28. Therefore, the panel 23 can be moved to the fully open position Z in FIG. 11 while being held in the tilted up state by the pivot shaft 37 and the pin 44 of the slider 27.

In the tilted-up panel 23 supported by the pins 44, the guide rail 25 is fixed to the roof 21 and the pins (supporting portions) 44 move along the guide rails 25. At the time of forward / backward movement with respect to the fully open position Z, it moves while maintaining its height with respect to the roof 21 and does not protrude greatly from the roof 21.

In this way, the pin 44 of the slider 27 is
, The cam groove 39 of the lifter 26, the pin 44 of the slider 27, etc. can be brought forward, and the head of the cam groove 39 can be reduced.
Accordingly, the opening efficiency is improved by that much, and the entire sunroof device can be made thinner.

12 and 13 show a second embodiment, in which a pin 70 is provided on the timing arm 29 separately from the pin 61, and a cam on which the pin 70 slides in addition to the tilt cam groove 58 on the elevating link 30. A groove 72 is provided so that the lifting link 30 is supported by the pin 70 before the panel 23 is fully closed and at the start of tilt, and the other lifting operation is performed by the pin 61. That is, when the weather strip 24 is in contact with the vertical wall surface of the roof 21 and has a large lifting resistance, the distance between the fixed shaft 50 and the pin 70 of the rear timing arm 29 is increased by supporting the pin 70.
Operation during lifting and lowering becomes smooth.

In the third embodiment shown in FIGS. 14 to 18, the overall structure and operation are the same as those of the first embodiment,
The shapes of the 39 'and the pin 44 and the structure of the tip of the lifting link 30 are different.

14 and 15, the pin 44 is formed in an oval cross section with flat upper and lower surfaces, the roller is not fitted, and the cam groove 3 is formed.
Reference numeral 9 'designates a rear groove portion 39b which engages with the pin 44 when the panel 23 is in the tilt-up position Y and the fully open position Z, and is formed as a narrow groove substantially in contact with the upper and lower flat surfaces of the pin 44. The pin 44 comes into surface contact with the flat surface of the pin 44 to receive a large load and prevent local abnormal friction due to line contact.

The front side of the rear groove portion 39b of the cam groove 39 'is wider than the cam groove 39 (shown by a two-dot chain line in FIG. 15) of the first embodiment, so that the contact is avoided when the pin 44 moves. When the pin 61 moves in the elevating cam groove 58 to move the panel 23 up and down around the pivot shaft 37, the pin 44 does not slide on the cam groove 39 '. The width W of the pin 44 and the rear groove 39b is smaller than the length T of the pin 44 in the front-rear direction, and the groove width Z on the front side of the rear groove 39b is larger than the length T.

That is, the distance from the pivot shaft 37 to the cam groove 39 ', the lifting cam groove 58, and the like has parts tolerances and allowable gaps, so that the pins 44, 61 simultaneously move while sliding on the respective grooves when the panel is raised and lowered. Is extremely difficult, and may be twisted or cause abnormal friction. By providing a gap between the pin 44 and the front side of the cam groove 39 ', tolerances and the like are absorbed.

In FIGS. 14, 16 to 18, the lifting link 30 is pivotally supported by a fixed shaft 56 and has a link portion 30a formed with a lifting cam groove 58.
The distance between the fixed shaft 56 and the pin 57 can be adjusted steplessly.

A concave portion 81 is formed on the side surface on the distal end side of the link 30a, and the concave portion 81 has a distal end portion 30b arranged so as to be adjustable in the longitudinal direction. Two long holes 8 long in the longitudinal direction are provided at the tip 30b.
2, 83 are formed, a screw 84 penetrates through the front long hole 82, the screw 84 is screwed into the link portion 30a, and the shaft portion 85a of the eccentric cam 85 is inserted into the rear long hole 83. This shaft part 85a is inserted
Is pivotally supported by the link 30a.

The eccentric cam 85 has a shaft portion 85a and a disk portion 85b whose center is shifted,
A rotary tool engagement groove 85c is formed in the disk portion 85b, and the disk portion 85b is in contact with a pair of protrusions 86 provided before and after the rear long hole 83.

When the eccentric cam 85 is rotated about the shaft portion 85a by a rotating tool, the eccentric cam 85 rotates between the pair of protrusions 86, so that the tip portion 30b is positioned at a distance twice the eccentric amount. Can be adjusted.

As described above, adjusting the length of the elevating link 30 adjusts the distance from the pivot shaft 37 to the elevating cam groove 58. The position of the groove 39 'can be adjusted so that the pin 44 can smoothly enter and exit the rear groove 39b.

(Effect of the Invention) According to the present invention, a guide rail is provided on the rear side of the opening 22.
An elevation member 30 for elevating and lowering the panel 23 with respect to 25 is provided.A timing arm 29 for operating the elevating member 30 in conjunction with the slider 27 only when the panel 23 is tilted is provided. Since the supporting portion 44 for supporting the panel 23 in the tilt-up state while maintaining the height with respect to the roof 21 when moving back and forth between the positions Z is provided, the tilt opening / closing force can be increased as compared with the related art. In addition, the panel 23 can be improved in high-speed responsiveness, the aperture efficiency can be improved, the overall thickness can be reduced, and the roof 23 can be moved from the tilt-up position Y to the fully open position Z in the tilt-up state. To the roof 21
