Technical Field

The present invention relates to a panoramic sunroof applied to a vehicle, and more particularly, to a rear rail for reducing an operation load of a panoramic sunroof, which removes contaminants attached in the rear rail of the panoramic sunroof to minimize the operation load, and a foreign matter removing apparatus in the rear rail.

Background

A panoramic sunroof, in which glass is provided on the entire surface of a vehicle roof to provide a lighting effect and an opening feeling, is classified into a partially-openable type in which glass can be partially opened and a fully-openable type in which glass can be fully opened. The glass constituting the sunroof is subjected to various heat treatments and light blocking treatments to block ultraviolet rays, infrared rays, and strong solar heat, and is made of a high-strength material to prevent passengers from being injured by glass fragments in the event of an accident.

The size of the glass of the panoramic sunroof is large compared to a general sunroof, so the mechanical structure for driving it is relatively complicated, and rear rails for moving the front glass when fully opened are disposed at both sides of the rear glass.

Fig. 1 is a view showing an application example of a panoramic sunroof 12 provided on a vehicle, and fig. 2 is a sectional view taken along line a-a of fig. 1.

As shown in the drawing, a roof frame 12a is fixed to the ceiling of the vehicle 10, and the sunroof 12 is mounted on the roof frame 12 a. The sunroof 12 includes: a rear glass 16 fixed to the roof frame 12 a; and a front glass 14 that can be opened or closed. In addition, guide devices 20 are provided on both sides of the rear glass 16.

The guide device 20 guides the reciprocating motion of the front glass 14, and includes: a rear rail 27 provided below a connecting portion between the rear glass 16 and the side molding 12 b; a tilt lever 21 reciprocatably supported on the rear rail 27; a guide shoe (guideshoe)23 fixed to a lower end portion of the tilting lever 21; the sealing member 25 seals a gap between the rear glass 16 and the side molding 12 b.

The conventional guide device 20 having the above-described structure cannot completely block the penetration of external dust or contaminants into the inner space 27a of the rear rail 27 even though the sealing member 25 is used. This is because the panoramic sunroof 12 is constructed such that only the rear rail is exposed.

In order to solve the above problem, sand, dust, etc. (hereinafter, collectively referred to as foreign materials a) are pushed out of the rear rail 27 by the guide shoe 23 fixed to the lower end portion of the inclined bar 21, but there is a limitation in removing foreign materials from the rear rail by the guide shoe 23. The reason for this will be described later by fig. 3 and 4.

Fig. 3 is a perspective view of the guide device 20 shown in fig. 2, and fig. 4 (a) and (b) are views for explaining problems of the conventional rear rail.

As shown in fig. 3, the conventional guide device 20 includes: a rear rail 27 extending in the longitudinal direction; a tilt lever 21 supported by the rear rail 27; and a guide shoe 23 fixed to a lower end of the tilting lever 21. The guide shoe 23 reciprocates along the longitudinal direction of the rear rail 27 together with the tilt rod 21, and pushes and discharges the foreign matter a inside the rear rail 27 to the outside of both end portions of the rear rail 27, that is, in the arrow a direction.

However, even if the guide shoe 23 is operated, if an excessive amount of foreign matter flows into the internal space 27a of the rear rail 27 or the foreign matter is gathered or fixed for various reasons, the foreign matter pushed out by the guide shoe 23 often gathers in the rear rail to cause a jam (jam) phenomenon, thereby hindering the operation of the panoramic sunroof.

That is, as shown in fig. 4 (a), in the process of moving the guide shoe 23 in the arrow b direction and pushing out the foreign matter a, the foreign matter a ahead is gradually accumulated, and the space ahead of the guide shoe 23 is closed as shown in fig. 4 (b). When the clogging phenomenon of foreign matter occurs, the operation load of the sunroof greatly increases, and noise, shaking, or the like is generated at the time of the opening or closing operation of the front glass, and the operation durability is reduced.

Detailed Description

An embodiment according to the invention is described in more detail below with reference to the accompanying drawings.

Basically, the rear rail of the present invention has a plurality of holes opened to the side and lower portions to enable foreign substances penetrating the inside of the rear rail to be rapidly discharged to the outside. Conventionally, since there is no separate foreign matter discharge hole and foreign matter is pushed to the end of the rear rail and discharged, the rear rail cannot be formed to have a sufficiently long length.

The rear rail is provided at both sides of a rear glass of the panorama sunroof, and provides a moving path of the inclined rod, and has an inner space inside thereof, in which a guide shoe coupled with the inclined rod is slidably received, and a foreign matter discharging part discharging foreign matters accumulated in the inner space to the outside of the inner space and discharging foreign matters pushed by the guide shoe in a direction orthogonal to a moving direction of the guide shoe is provided on the moving path of the guide shoe.

Fig. 5 is a perspective view showing the guide 20 of the rear rail 30 and the tilting lever together according to one embodiment of the present invention. The rear rail 30 shown in fig. 5 is a conceptual diagram, and the actual rear rail 30 may have the shape of fig. 6. Different vehicles may have different shapes of the rear rail 30.

Referring to fig. 5, the lower end of the tilting lever 21 is inserted into the rear rail 30 extending in the longitudinal direction. The tilt lever 21 is a member coupled to both end portions of the front glass, and has a guide shoe 23 at a lower end portion thereof.

On the other hand, a plurality of side holes 31 and lower holes 33 are formed at the rear rail 30. The side holes 31 and the lower holes 33 are through holes located on the path of the guide shoe 23, and are channels for discharging foreign substances accumulated in the inner space of the rear rail 30 to the side and lower portions. That is, the side holes and the lower holes are foreign matter discharge portions that discharge foreign matter in a direction orthogonal to the moving direction of the guide shoe 23.

Both end portions of the rear rail 30 are opened by the discharge end portion 30a in fig. 5, but the discharge end portion 30a may be removed in the case of using the side hole 31 and the lower hole 33.

The number of such side holes 31 and lower holes 33 used or the size or shape of the holes may be changed as desired.

In particular, as shown in fig. 11, a blade portion 34 may be formed at the inner edge portions of the side hole 31 and the lower hole 33. The blade portion 34 is formed by cutting the edges in the thickness direction of the inside of the side hole 31 and the lower hole 33 into sharp blades, and functions to peel off foreign matter stuck to the guide shoe 23 from the guide shoe and discharge the foreign matter to the direction of arrow d shown in fig. 11, that is, to the outside of the rear rail 30. The foreign matter can be discharged more easily and quickly using the blade portion 34.

Fig. 6 is a plan view of the rear rail 30 according to an embodiment of the present invention, and fig. 7 is a sectional view taken along line B-B of fig. 6. Fig. 8 is a cross-sectional view taken along line C-C of fig. 6.

As shown in the drawing, the rear rail 30 forms an inner space portion 30c that can accommodate the guide shoe 23 or the cleaner 41 of fig. 9. An example using the cleaner 41 will be described below.

The rear rail 30 is formed with a side wall portion 30f, a first bottom portion 30d, and a second bottom portion 30 e. The side wall portion 30f is a portion that contacts the side surface of the guide shoe 41a of the cleaner 41, and the first bottom portion 30d is a portion that contacts the bottom surface of the guide shoe 41 a. In addition, the second bottom 30e is a portion forming a step with the first bottom 30d, which is spaced in parallel with the side stopper 41 b. The side wall portion 30f and the first bottom portion 30d function as a support surface for guiding the reciprocating movement of the cleaner 41.

The side wall portion 30f is formed with a plurality of side holes 31. The side holes 31 are arranged at predetermined intervals in the lengthwise direction of the rear rail 30, and are passages through which foreign substances inside the rear rail 30 are discharged to the outside.

In addition, a lower hole 33 is provided in the second bottom 30 e. The lower holes 33 are arranged at predetermined intervals in the longitudinal direction of the rear rail 30, similarly to the side holes 31, and discharge foreign substances inside the inner space 30c to the lower portion.

As described above, the inner sides of the side holes 31 and the lower holes 33 may be formed with the blade parts 34.

Fig. 9 is a sectional view illustrating a foreign material removing apparatus 40 according to an embodiment of the present invention together with a rear rail 30, and fig. 10 is a partial perspective view of the foreign material removing apparatus shown in fig. 9.

As shown in fig. 9, the foreign matter removing apparatus 40 of the present embodiment operates in a state of being slidably inserted into the inner space portion 30c of the rear rail 30. That is, foreign substances inside the rear rail 30 are discharged through the side holes 31 and the lower holes 33 while sliding.

The foreign material removing apparatus 40 includes: a cleaner 41 fixed to the lower end of the tilt lever 21; and a brush 41c fixed to the cleaner 41.

In addition, cleaner 41 includes: a guide shoe 41a supported in surface contact with the side wall portion 30f and the first bottom portion 30 d; and a side stopper 41 b. The side stopper 41b is a belt-shaped member of a predetermined thickness integrally formed at a side portion of the guide shoe 41a, and is spaced apart from an upper portion of the second bottom portion 30e by a predetermined interval.

Also, a plurality of brush installation grooves 41e are formed in the guide shoe 41 a. The brush arrangement groove 41e is a groove in which a plurality of grooves are formed at predetermined intervals along the longitudinal direction of the guide shoe 41a, and accommodates the brush 41c therein.

The brushes 41c extend to the side, upper and lower portions to contact the rear rail 30 in a state of being accommodated in the respective brush installation grooves 41 e. The brush 41c can sweep away foreign matter contaminating the inner wall surface of the rear rail 30.

The side slider 41b also has brushes 41c on the bottom surface and the side surfaces thereof. The brush 41c fixed to the side stopper 41b plays a role of sweeping foreign substances adhering to the second bottom portion 30e and the right side wall portion 30k of the second bottom portion 30e in the drawing. As described above, the bottom surface of the side stopper 41b is spaced in parallel from the second bottom 30e and fixes the brush 41 c.

The sweeper 41 having the above-described structure may be subjected to semi-hard anodizing treatment to prevent abrasion of the rear rail 30.

Fig. 11 and 12 are views for explaining the operation of the foreign material removing apparatus shown in fig. 9.
