European Patent Publication 1741588A1

  In the method of determining the completion position of the tilt-up of the roof panel by the contact restriction by the stopper, there is a problem that a structure for attaching the stopper is complicated and a collision sound is also generated. For this reason, a method of stopping rotation of the front slider and the rear slider drive motor at a predetermined pulse count value is generally used for the tilting completion position of the roof panel. However, if the position of the roof panel shifts with respect to the pulse count value of the drive motor due to an external load, etc., the roof panel still reaches the complete tilt-up completion position when the drive motor stops rotating. It can happen that it has not been reached.

  For example, referring to the structure of Patent Document 1, since the lift guide pin on the front slider side is located at the inclined portion of the lift guide groove when the tilt up is completed, the roof with respect to the pulse count value of the drive motor When the panel is displaced, the height of the lift guide pin is displaced by the vertical component of the inclined portion, and the roof panel tilt-up completion position varies.

  In addition, due to an assembly error between the roof panel side and the front slider and the rear slider side, there is a possibility that variations in the tilt-up completion position of the roof panel may occur for each product.

  The present invention has been created to solve such a problem, and even when a positional deviation or an assembling error occurs in the roof panel, the roof panel can be held at a normal tilt-up completion position. The object is to provide a sunroof device.

  In order to solve the above-mentioned problems, the present invention provides a roof panel that can be freely opened and closed on a fixed roof of a vehicle, and a pin engaging portion that includes a lift guide groove and a lift guide pin that slides in the lift guide groove. A front slider and a rear slider that are connected to the front and rear sides of the roof panel and move together to tilt the roof panel up by the pressing action of the pin engaging portion; and the front slider and the rear slider. In the sunroof device having a drive motor for driving, a horizontal groove for a tilt-up completion position is formed in a part of each lift guide groove, and when the roof panel is tilted up, each lift guide pin is It is characterized by being positioned in each horizontal groove.

  According to this sunroof device, since the two lift guide pins are both positioned in the horizontal groove, even if the position of the roof panel is deviated from the pulse count value of the drive motor due to an external load or the like, The displacement is absorbed by each lift guide pin sliding in the horizontal direction in the horizontal groove. Similarly, even if there is an assembly error between the roof panel side and the front slider and the rear slider side, the error is absorbed by each lift guide pin sliding in the horizontal direction in the horizontal groove. As a result, the roof panel is held at the normal tilt-up completion position without causing variations in the vertical position.

  The present invention also relates to the horizontal stroke from the position of the roof panel when the roof panel is fully closed to the position where the horizontal groove is reached, the horizontal stroke on the front slider side being the horizontal stroke on the rear slider side. The lift guide pin on the front slider side is positioned in the horizontal groove earlier than the lift guide pin on the rear slider side when tilting up.

  Tilt-up of the roof panel is mainly performed for the purpose of ventilation inside the vehicle. The rear edge of the roof panel is raised to ensure a predetermined opening, while the front edge of the roof panel is driven by wind, rain, etc. In order to prevent intrusion and the like, no opening is formed between the fixed roof and the like. However, if only the rear edge of the roof panel is lifted without any upward displacement of the front edge of the roof panel, the roof panel will rise so that the rear edge of the roof panel draws an arc around the front edge side. The front edge (specifically, the weather strip attached to the front edge) may be rubbed against the edge of the vehicle body roof so that an unreasonable load is applied. On the other hand, the roof panel is moved substantially in parallel at the initial stage of the tilt-up operation by slightly raising the roof panel on the front edge side so that an opening is not formed between the roof panel and the vehicle body side roof. And the problem of twisting can be solved. However, even in this case, since the front edge of the roof panel rises so as not to form an opening with respect to the vehicle body side roof, a slight rubbing of the front edge of the roof panel with respect to the vehicle body side roof occurs.

  Against this background, the horizontal stroke from the position of the lift guide pin when the roof panel is fully closed to the position where the horizontal groove is reached is a factor that determines the operation time for tilting up the roof panel, and the horizontal stroke is short. The tilt up is completed in a short time. In the present invention, the horizontal stroke on the front slider side is set smaller than the horizontal stroke on the rear slider side, and the lift guide pin on the front slider side is set to the lift guide pin on the rear slider side when tilting up. The operation time for tilting up the front edge of the roof panel is shortened by positioning in the horizontal groove earlier. As a result, the rubbing time of the front edge of the roof panel against the roof on the vehicle body side can be shortened, and the rubbing noise can be reduced and the damage to the front edge of the roof panel can be reduced.

  According to the present invention, the roof panel is held at the normal tilt-up completion position without causing variations in the vertical position.

"Action"
The operation of the sunroof device 1 will be described mainly with reference to FIG. FIG. 6A shows a state in which the roof panel 3 is fully closed. At this time, the front slider 7 and the rear slider 8 are at the most advanced position. The first lift guide pin 17 is positioned at the first horizontal stroke 15 </ b> A of the first lift guide groove 15 and at the lower part of the inclined groove 19 </ b> B of the pin guide groove 19. The second lift guide pin 35 is located at the first horizontal stroke 26 </ b> A of the second lift guide groove 26 and at the lower part of the arc pin guide groove 29. The link arm 30 is stored in a lying state, and the first connecting pin 33 is located at the rear end of the long hole 32.

  Since both the first lift guide pin 17 and the second lift guide pin 35 are located in the first horizontal stroke 15A and the first horizontal stroke 26A, which are horizontal grooves, the pulse count value of the drive motor M is affected even by an external load or the like. Even if the position of the roof panel 3 is shifted, the first lift guide pin 17 and the second lift guide pin 35 respectively move the first horizontal stroke 15A and the first horizontal stroke 26A in the lateral direction. Absorbed by sliding. Similarly, even if there is an assembly error between the roof panel 3 side and the front slider 7 and the rear slider 8 side, the error is caused by the first horizontal guide stroke 17 and the second lift guide pin 35, respectively. 15A, absorbed by sliding the first horizontal stroke 26A laterally. As a result, the roof panel 3 is in the normal fully closed position without causing variations in the vertical position.

  When the front slider 7 and the rear slider 8 integrally move rearward through the push-pull cable 11 by driving the motor M from the state of FIG. 6A, as shown in FIG. The inner wall of the first inclined stroke 15B of the guide groove 15 pushes the first lift guide pin 17 upward, and the inner wall of the inclined stroke 26B of the second lift guide groove 26 pushes the second lift guide pin 35 upward. The first lift guide pin 17 rises while being slightly displaced rearward by being guided by the inclined groove 19B, and the second lift guide pin 35 is also slightly rearward by being guided by the arc pin guide groove 29. Ascend while moving. The roof panel 3 rises in a substantially parallel manner so as not to form an opening with the front garnish 5 in the initial stage of tilt-up. As described above, the arc pin guide groove 29 is formed so as to draw an arc around the position of the connecting pin 34 when the roof panel 3 is fully closed, so that the second lift guide pin is formed in the arc groove. In the process of ascending 35, the position of the second connecting pin 34 hardly changes, and therefore the link arm 30 stands up with the second connecting pin 34 at a substantially fixed position as the center of rotation. During this time, the first connecting pin 33 moves to the front side of the long hole 32.

  In this way, by raising the link arm 30 with the second connecting pin 34 at a substantially fixed position as the center of rotation, a force for pulling the second connecting pin 34 forward is not required, and the second lift guide groove 26 defines the second connecting pin 34. The pressing force applied to the two lift guide pins 35 can be efficiently converted into the standing force of the link arm 30, and the standing operation of the link arm 30 can be made smooth throughout.

  In addition, the first connecting pin 33 is slidably engaged with the relief groove 31 formed in the link arm 30 so that the arc of the first connecting pin 33 centered on the second connecting pin 34 at a fixed position is obtained. And the difference between the desired rising locus of the rear edge of the roof panel 3 can be smoothly absorbed. Even if the first connecting pin 33 is provided on the link arm 30 and the escape groove 31 is formed on the roof panel side, specifically, on the second panel bracket 27, the same effect can be obtained.

  As shown in FIG. 3, the horizontal stroke a on the front slider 7 side is set smaller than the horizontal stroke b on the rear slider 8 side, and the first lift guide pin 17 has the second horizontal stroke. Since the timing at which the second lift guide pin 35 is positioned at the second horizontal stroke 26C is earlier than the timing at which the second lift guide pin 35 is positioned at 15C, the operation time for tilting up the front edge of the roof panel is shorter than the rear edge of the roof panel. . Thereby, the time for which the front edge of the roof panel 3 (specifically, the weather strip 36) rubs against the front garnish 5 can be shortened, and the rub sound and the damage to the weather strip 36 can be reduced.

  FIG. 6C shows a state in which the tilt up of the roof panel 3 is completed. In this state, the first lift guide pin 17 is positioned at the second horizontal stroke 15 </ b> C of the first lift guide groove 15. At the same time, the first lift guide pin 17 is positioned around the upper portion of the inclined groove 19B of the pin guide groove 19, but does not reach the height position of the horizontal groove 19A. On the other hand, the second lift guide pin 35 is positioned at the second horizontal stroke 26 </ b> C of the second lift guide groove 26. At the same time, the second lift guide pin 35 is positioned at the upper end of the arc pin guide groove 29. The position of the upper end is the same as the height position of the upper pin guide groove 22 of the rear guide rail 10.

  Since both the first lift guide pin 17 and the second lift guide pin 35 are positioned in the second horizontal stroke 15C and the second horizontal stroke 26C, which are horizontal grooves, the pulse count value of the drive motor M is affected by an external load or the like. Even if the position of the roof panel 3 is shifted, the first lift guide pin 17 and the second lift guide pin 35 respectively move the second horizontal stroke 15C and the second horizontal stroke 26C in the lateral direction. Absorbed by sliding. Similarly, even if there is an assembly error between the roof panel 3 side and the front slider 7 and the rear slider 8 side, the error is caused by the first horizontal guide stroke 17 and the second lift guide pin 35 respectively in the second horizontal stroke. 15C, absorbed by sliding the second horizontal stroke 26C in the lateral direction. As a result, the roof panel 3 becomes a normal tilt-up completion position without causing variations in the vertical position. Since the first lift guide pin 17 is positioned in the inclined groove 19B of the pin guide groove 19 as described above at the position where the tilt up of the roof panel 3 is completed, the roof panel 3 is the front slider 7 and the rear slider. 8 does not swing back and forth.

  When the front slider 7 and the rear slider 8 are moved further rearward from the state of FIG. 6C, the inner wall of the second inclined stroke 15D of the first lift guide groove 15 pushes the first lift guide pin 17 upward. The first lift guide pin 17 rises while being displaced rearward by being guided by the inclined groove 19B. When the first lift guide pin 17 is fully raised, the first lift guide pin 17 is guided rearward by being guided by the horizontal groove 19A as shown in FIG. 6 (d). Move horizontally. On the other hand, the second lift guide pin 35 is pressed against the inner wall of the front end of the second horizontal stroke 26 </ b> C of the second lift guide groove 26, and is horizontally moved backward by being guided by the upper pin guide groove 22. Since the second connecting pin 34 is also guided by the lower pin guide groove 23 and horizontally moves rearward, the link arm 30 is moved backward while maintaining the same posture by the two-point support of the second lift guide pin 35 and the second connecting pin 34. Move horizontally. That is, the roof panel 3 further moves up only from the front edge side and moves backward from the state where the tilt-up is completed.

When the roof panel 3 is moved, the second panel bracket 27 and the link arm 30 pass through the gap between the fixed panel 4 and the side garnish 6 as shown in FIG. 27 and the link arm 30 pass through the seal lip 38 that closes the gap between the fixed panel 4 and the side garnish 6 so as to be locally pushed.
The operation when the roof panel 3 is closed is the reverse of the above operation, and the description thereof is omitted.

  The preferred embodiments of the present invention have been described above, but the present invention is not limited to those described in the drawings, and various design changes can be made without departing from the spirit of the present invention.
