[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sunroof device, and more particularly to an inner slide type sunroof device improved so as not to rattle when a slide panel is tilted down to perform an opening / closing motion.
[0002]
[Prior art]
An inner slide type sunroof device is known in which a slide panel that opens and closes an opening provided in a fixed roof of a vehicle is tilted down and then retracted below the fixed roof (Japanese Patent Laid-Open No. 2-290717). Etc.)
[0003]
In such a sunroof device, sliders slidably engaged with guide rails fixed below the fixed roof are connected to the front and rear end portions of the left and right side portions below the slide panel, and the slide panel has a lateral direction at the rear end portion. A structure is known in which a pin is protruded and engaged with a guide groove formed in a guide rail so as to restrict vertical movement when the slide panel performs an opening / closing motion.
[0004]
[Problems to be solved by the invention]
However, a predetermined tolerance (allowable error) needs to be set between the width dimension of the guide groove and the outer diameter dimension of the pin for the convenience of manufacturing and assembly. Depending on the situation, it is inevitable that a certain amount of rattling occurs during the opening and closing movement of the slide panel.
[0005]
The present invention has been devised to solve such problems of the prior art, and its main purpose is to further reduce the rattling when the slide panel performs opening and closing movements. The object is to provide an improved sunroof device.
[0006]
[Means for Solving the Problems]
In order to achieve such an object, the present invention aims to retract the slide panel (3) that opens and closes the opening (2) provided in the fixed roof (1) of the vehicle and then pulls it down below the fixed roof. A slide that is slidably engaged with a panel stay (6) fixed below the left and right sides of the slide panel and a guide groove (13) of a guide rail (15) fixed on the fixed roof side and connected to the panel stay In a sunroof device having a member (9) and a pin (11) that protrudes from the rear end of the panel stay and engages with the guide groove when tilted down, corresponds to at least one slide member and the slide member of the panel stay between the portions, provided with a resilient member (23) for applying a pressing force to the panel stay when the guide groove pin performs engage closing movement, before The starting end of the guide groove in the guide rail, were to be arranged introduction member made of introduction groove (16) an elastic material formed is to introduce the pin when the tilt-down of the slide panel (15).
[0007]
In this way, for example, when the lower surface of the panel stay comes into contact with the elastic member provided on the upper surface of the bottom of the slide member when the slide panel is tilted down, the guide groove is caused by the pressing force generated by the elastic member. A pin is pressed against one side. Thereby, the clearance gap between a guide groove and a pin is canceled.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[0009]
FIG. 1 is a perspective view of an essential part of a vehicle showing an outline of a sunroof device to which the present invention is applied. A fixed roof 1 of the vehicle is formed with an opening 2 having a substantially rectangular shape with a long side in the vehicle body width direction. The opening 2 can be opened and closed by a slide panel 3 formed in a shape corresponding to the inner peripheral contour of the opening 2.
[0010]
As shown in FIGS. 2 to 4, the slide panel 3 includes a glass holder 4 that forms a rectangular frame corresponding to the inner peripheral contour of the opening 2, and a glass panel that is fixed above the glass holder 4 using, for example, an adhesive. 5 and a pair of left and right panel stays 6 integrally coupled to both left and right side portions below the glass holder 4 via a connecting member 4a (FIG. 4).
[0011]
The panel stay 6 extends in the front-rear direction. A front slider 7 is pivotally attached to the front end of the panel stay 6, and a cam groove 8 is formed on the side surface of the rear part of the panel stay 6. A cam follower 10 provided on the rear slider 9 is engaged with the cam groove 8. In addition, a pin 11 protrudes laterally at the rear end.
[0012]
On the indoor side of the fixed roof 1, a guide is provided with a lower guide groove 12 in which the front and rear sliders 7 and 9 are always slid and an upper guide groove 13 in which the lateral pin 11 at the rear end of the panel stay is slid when the slide panel 3 is opened and closed. A rail 14 is fixed.
[0013]
At an appropriate position in the front-rear direction of the upper guide groove 13 formed in the guide rail 14, as shown in FIG. 5, an introduction member 15 formed of a synthetic resin material rich in elasticity is attached. An introduction groove 16 having a groove width substantially equal to that of the upper guide groove 12 is formed on the side surface of the introduction member 15. The introduction groove 16 extends slightly downward in the vertical direction from the starting end opened upward, and then extends backward with a gentle arc and is connected to the upper guide groove 13 as it is.
[0014]
The basic operation of this sunroof device is the same as that of a known one, and the inside of the cable guide 17 having a C-shaped cross-section formed inside the guide rail 14 and formed above the outer lower guide groove 12 is opened. The push / pull cable 18 inserted into the rear slider 9 is connected to the side surface of the rear slider 9, and the push / pull cable 18 is driven by an electric motor (not shown) to move the rear slider 9 back and forth. Thus, the slide panel 3 is driven to open and close.
[0015]
When the rear slider 9 is moved rearward from the fully closed position of the slide panel 3 (the state shown in FIG. 2), the cam follower 10 provided on the rear slider 9 engages with the cam groove 8 formed on the panel stay 6. Therefore, the slide panel 3 first sets the pivot point of the front end of the panel stay 6 with respect to the front slider 7 as the rear slider 9 moves rearward due to the vertical and longitudinal components of the cam groove 8. Tilt in the direction of lowering the trailing edge as a center (tilt down operation).
[0016]
By this tilt-down operation, the pin 11 projecting laterally at the rear end of the panel stay 6 enters the upward opening of the start end of the introduction groove 16 formed in the introduction member 15, and the upper guide with the introduction groove 16 It is smoothly guided to the groove 13 (see FIG. 3). At this time, since the introduction member 15 is formed of a synthetic resin material rich in elasticity, the pin 11 can hit the introduction groove 16 without generating a hitting sound.
[0017]
On the other hand, the lower guide groove 12 of the guide rail 14 has the open surfaces of a pair of grooves having a U-shaped cross section opposed to each other, and the rear slider 9 slidably engaged with the lower guide groove 12 enters the left and right lower guide grooves 12. A lateral projection 21 is provided. The projections 21 are fitted with slide shoes 22 formed of a synthetic resin material having a low friction coefficient and not easily worn.
[0018]
An elastic member 23 made of an elastomer material rich in elasticity is attached immediately below the cam follower 10 at the intermediate portion in the left-right direction of the rear slider 9. The elastic member 23 is configured such that when the slide panel 3 is tilted down, the lower surface of the panel stay 6 comes into contact with the upper surface and is somewhat compressed and deformed.
[0019]
Therefore, when the rear slider 9 is pulled and driven rearward in this state, the slide panel 3 is accommodated below the fixed roof 1 with the rearward movement of the front and rear sliders 7 and 9 slidably engaged with the lower guide groove 12. At this time, when the front end of the panel stay 6 is pivotally supported by the front slider 7 slidably engaged with the lower guide groove 12 and the pin 11 of the rear end is slidably engaged with the upper guide groove 13, the panel stay 6 moves up and down. Is regulated. Moreover, since the upward reaction force of the elastic member 23 acts on the panel stay 6 and the pin 11 is pressed against the upper surface of the upper guide groove 13, the gap between the upper guide groove 13 and the pin 11 is substantially reduced. Canceled, rattling of the pin 11 in the upper guide groove 13 is suppressed.
[0020]
In short, the elastic member 23 is only required to be sandwiched between the lower surface of the panel stay 6 and the bottom surface of the slider and to be somewhat compressed and deformed when the slide panel 3 is tilted down. It may be provided not only on the bottom of the rear slider 9 shown in FIG. 5 but also on the front slider 7 side, or on the panel stay 6 side.
[0021]
【The invention's effect】
According to the present invention, during opening and closing operations of the sliding panel in the sunroof device, since the elastic member in between the bottom and the panel bottom surface of the stay of the slider has to be compressed and deformed, the starting end of the guide groove Combined with the fact that no impact sound is generated when the pin enters the introduction groove because the introduction member formed of an elastic member is provided, it is possible to suppress the occurrence of the impact sound when the slide panel is tilted down. . In addition, since the pin is pressed against the upper surface of the sliding groove of the guide rail by the upward reaction force of the elastic member, it is possible to simultaneously suppress the shakiness of the slide panel , and to the panel stay by the elastic member. since the upward reaction force introduced acts member is elastically deformed, Ru can be smoothly guided pins in the guide groove.
