Description

Fabric deflector noise reduction and storing guidance device for panoramic sunroof in vehicle}

The present invention relates to a panoramic sunroof for a vehicle, and more specifically, to prevent the occurrence of resonance caused by a deflector bar, improve wind noise when driving, enable low noise operation, and guide the storage of a fabric deflector for quick and accurate opening and closing. The invention relates to a fabric deflector noise reduction and storage induction device for an induction vehicle panoramic sunroof.

In the panoramic sunroof, which provides light and openness by placing glass on the entire ceiling of the vehicle, there are a partially open type that partially opens the glass and a completely open type that can be completely opened. The glass constituting the sunroof is subjected to various heat treatments and shading treatments to block strong solar heat as well as ultraviolet rays and infrared rays. Furthermore, the glass is made of a high-strength material so as not to injure passengers on debris in case of accident.

Such a panoramic sunroof has a larger size of glass than a normal sunroof, so the mechanical structure for driving it is relatively complex. For example, a driving device or a rear rail for moving the windshield is provided on both sides of the rear glass. It has an arranged structure.

On the other hand, a deflector is installed in front of the opening of the roof panel equipped with the panoramic sunroof. The deflector functions to prevent the wind coming into the vehicle directly through the opening when driving with the sunroof open. For example, it bounces the driving wind and raises the stream line up.

The sunroof deflector has a power type that operates using a separate electric transmission device, and a spring type that uses the elastic force of the spring. The spring type deflector automatically rises when the front glass is opened, and when it is blocked, it is pushed down by the front glass.

Further, the deflector may be divided into an outer type positioned in front of the weather strip fixed to the front frame and an inner type positioned behind the weather strip. The outer type deflector is quick to rise and is advantageous for blocking noise, and is also advantageous over the inner type deflector in terms of the open length of the glass.

1 and 2 are configuration diagrams for explaining the basic structure and problems of the inner type deflector 21. 1 is a state in which the deflector 21 is fully deployed, and FIG. 2 is when collecting the deflector 21 into the storage space 17.

As shown in FIG. 1, a lower fixing plate 15 is installed at a rear end of the front frame 13, and a deflector 21 is connected to the lower fixing plate 15. The deflector 21 is made of a fabric material and has a deflector seal 23 at its lower end. The deflector seal 23 is coupled to the deflector 21 by a sewing method and is mounted on the lower fixing plate 15. The lower fixing plate 15 supports the deflector 21 through the deflector seal 23 in a state accommodated in the storage space 17.

In addition, the deflector bar 25 is fixed to the upper end of the deflector 21. The deflector bar 25, for example, maintains a raised state by the above-described spring and supports the deflector 21 taut.

However, in the above-described conventional deflector 21, when the sunroof is blocked, the deflector 21 is often not easily accommodated in the storage space 17. In other words, it is difficult to regulate the folding direction of the deflector.

For example, when the reverse direction of the arrow a is applied while the deflector bar 25 is descending, the deflector 21 is folded forward as shown in FIG. 2 and may overlap the upper portion of the weather strip 19. Since the front glass (not shown) descends on the upper side of the weather strip 19, the deflector 21 is interposed between the weather strip 19 and the front glass. The panorama sunroof is not sealed.

In addition, the deflector bar trembles due to the impact of the wind hitting the deflector bar 25, and also generates a resonance sound, and also has the inconvenience of generating wind noise inside the gap between the front frame 13 and the lower fixing plate 15. .

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

Basically, the noise reduction and storage induction device of the present invention is provided in a front frame of a panoramic sunroof, and is installed in a storage space accommodating a deflector portion composed of a fabric deflector and a deflector bar, and accommodates the lower portion of the deflector, but is slit. A rear opening holder which provides a space part opened rearward in the vehicle traveling direction through the passage; It is installed on the upper portion of the rear opening holder, and has a basic structure of a noise reduction unit that attenuates noise generated by air flowing from the outside into the storage space.

3 to 5 are views for explaining the overall structure and operation of the fabric deflector noise reduction and storage induction device for a vehicle panoramic sunroof according to an embodiment of the present invention.

3 shows a state in which the sunroof is opened, that is, the deflector bar 25 is raised to the maximum, and FIG. 5 shows a state in which the sunroof is closed and the deflector unit 20 is completely accommodated in the storage space 17.

As shown, the noise reduction and storage induction device according to the present embodiment includes a rear opening holder 41 and a noise reduction watch 45 mounted in the storage space 17.

The rear opening holder 41 supports the deflector unit 20 and serves to guide the deflector unit into the storage space 17. In addition, the noise reduction watch 45 attenuates resonance noise generated by air flowing in from the outside. The noise reduction watch 45 is an example of an implementation of the noise reduction unit, and as long as it can process resonance noise or other noise, its shape may vary.

The deflector portion 20 has a deflector 21 made of a fabric material, a deflector bar 25 fixed to an upper portion of the deflector 21, and a deflector seal 43 fixed to a lower portion. The deflector seal 43 is a strip-shaped member extending in the width direction of the deflector 21 and is partially fixed to the lower end of the deflector 21. That is, only a part of the deflector seal 43 in the width direction (left end in the drawing) is fixed and the right end is open.

First, the rear opening holder 41 is a member extending in the width direction of the deflector 21, and has a deflector supporting portion 41f, a hook portion 41d, a locking groove 41g, and a supporting projection 41h. It provides a space portion (41a) for receiving and fixing the lower end of the deflector portion (20).

The space portion 41a is opened to the rear of the vehicle through a slit-shaped passage 41b of a certain width. The passage 41b passes the deflector 21 as a gap between the deflector support portion 41f and the hook portion 41d.

The deflector support portion 41f supports a deflector 21 folded in a receiving state as shown in FIG. 5 as a horizontally maintained plane. The width of the deflector support portion 41f is preferably as wide as possible inside the storage space 17.

In addition, in the deflector supporting portion 41f, a supporting protrusion 41h is formed at a portion included in the space portion 41a. As shown in Fig. 4, the supporting protrusion 41h lifts the lower end of the deflector 21 in the direction of the arrow t, so that the deflector seal 43 spreads upward from the deflector 21 and engages the locking groove 41g. . The deflector seal 43 prevents the deflector 21 from deviating in the direction of the arrow p in the state of being caught in the engaging groove 41g.

The hook portion 41d is positioned on the upper portion of the passage 41b, that is, on the upper portion of the deflector support portion 41f and has a shape bent toward the space portion 41a. In particular, the above-mentioned engaging groove 41g is formed in the inner portion of the hook portion 41d, that is, toward the space portion 41a, and the supporting curved portion 41c is provided on the opposite side. The supporting curved surface portion 41c supports the lower end portion of the deflector 21 that is kept tight as a streamlined curved portion. Since the support curved portion 41c takes a streamlined shape, there is no fear of tearing the lower end portion of the deflector 21.

Further, the farther the distance X from the inner wall surface 13a of the storage space 17 to the support curved portion 41c is, the better. This is because the weather strip 19 does not reach the distance when the deflector 21 is folded forward by receiving the wind pressure in the direction of the arrow a (when the deflector descends). The distance X is about half of the distance from one end of the storage space 17 to the other end.

In addition, a guide rail 41e is formed on the rear opening holder 41. The guide rail 41e is a linear protrusion extending forward and backward in the traveling direction of the vehicle, and supports the slider 45a provided under the noise reduction watch 45. The slider 45a is a member that can be positioned in the front-rear direction while being supported by the guide rail 41e.

As described above, since the position of the noise reduction watch 45 disposed on the upper portion of the rear open holder 41 can be adjusted, for example, the noise reduction watch 45 is moved in the direction of the arrow b, as shown in FIG. It is possible to more effectively contact the deflector bar 25 in one state.

On the other hand, the noise reduction watch 45, as mentioned above, as an example of a noise reduction unit that can be implemented in various ways, takes the form that both ends are bent upward in the drawing. The noise reduction seal 45 is made of silicone or rubber.

The left end of the noise reduction watch 45 is in line contact with the inner wall surface 13a of one side of the storage space 17, and the right end of the other side is in contact with the deflector 21 as the blocking section 45b. By bending both ends of the noise reduction seal 45, the assembling property is improved and the generation of noise is suppressed by forming a line contact structure.

In addition, the noise reduction watch 45, by blocking the gap between the inner wall surface (13a) and the rear opening holder (41), prevents the running wind from entering the gap. When the driving wind enters the gap, the wind turns around the lower portion of the rear opening holder 41 and falls into the rear space of the deflector 21 to directly enter the vehicle interior. Moreover, of course, noise and vibration are generated while the wind passes through the path.

As a result, the noise reduction facility 45 induces the oncoming driving wind in the direction of the arrow e to block the entry into the room and suppress the occurrence of noise and vibration.

In addition, the blocking portion 45b serves to block the deflector 21 from leaning toward the weather strip 19 and prevents resonance of the deflector bar 25 by coming into contact with the deflector bar 25 in a descending state. Doubles. As described above, since the noise reduction seal 45 is made of rubber or silicon, and the deflector bar 25 is made of a hard synthetic resin, the natural frequencies between the two are different. Therefore, when the noise reduction seal 45 is in close contact with the deflector bar 25, the resonance phenomenon in the deflector bar 25 can be improved by the action of the noise reduction seal 45.

6 is a cross-sectional side view showing another example of a fabric deflector noise reduction and storage induction device for a panoramic sunroof for a vehicle according to an embodiment of the present invention.

The same reference numerals as the above-mentioned reference numerals refer to the same members having the same function.

The noise reduction unit shown in FIG. 6 is a block-type noise reduction block 47 in which an air passage is formed. The noise reduction block 47 is made of soft silicone or rubber, and ends in the front-rear direction contact the inner wall surface 13a and the deflector 21, and plays the same role as the deflector seal 43 described above.

In the noise reduction block 47, the surface in contact with the deflector 21 is a blocking portion 47f, which prevents the deflector from being folded forward due to a reverse wind when the deflector 21 descends.

In particular, a deflector bar support groove 47e is formed on an upper portion of the blocking portion 47f. The deflector bar support groove 47e is a groove that partially receives the deflector bar 25 in a lowered state and absorbs vibration transmitted from the deflector bar 25. The deflector bar 25 is fitted to the deflector bar support groove 47e in a descending state, and is in close contact. Of course, the larger the contact area, the greater the effect of improving vibration damping and resonance.

On the other hand, in the noise reduction block 47, an induction curved portion 47a, an inlet portion 47b, a resonance attenuation space portion 47c, and an outlet portion 47d are formed. The induction curved portion 47a is a portion that collects driving wind and guides it to the inlet portion 47b. The inlet portion 47b passes air introduced by the induction curved portion 47a and sends it to the resonance attenuating space portion 47c.

The resonance attenuation space portion 47c has a larger flow cross-sectional area than the flow cross-sectional area of the inlet portion 47b, and prevents resonance. The air that has passed through the resonance attenuating space portion 47c is discharged to the atmosphere through the outlet portion 47d and hits the deflector 21 and flows upward.

In addition, a slider 47k is provided below the noise reduction block 47. The slider 47k is supported by the guide rail 41e installed on the upper portion of the rear opening holder 41, so that the position of the noise reduction block 47 can be adjusted back and forth as necessary.

As described above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications can be made by those skilled in the art within the scope of the technical spirit of the present invention.
