Description

[0001] A CRASH PAD ASSEMBLY INCLUDING DEFROSTER WITH A DEFROSTOR [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a crash pad assembly having a defroster, and more particularly, to a crash pad assembly including a defroster capable of easily removing a property occurring at a center of a windshield and a bottom of a side surface.

A defroster is a device that attaches to a front window of a driver's seat in a car and removes it by frost or icy snow so that the view is not blurred.

Korean Patent Laid-Open No. 10-2007-0005263 discloses a " channel structure of a defrosting duct for a vehicle ", specifically, a front duct portion defrosting a front glass for a vehicle is divided into a first front duct and a second front duct, The side duct portion defrosting the side glass is divided into the second side duct and the second side duct so that the air introduced through the suction portion partitioned into the lattice shape is moved to each divided space, It is described that uniform blowing is performed not only in the center but also in the left and right sides.

The defroster device is used to remove a windshield of a vehicle when a wind or the like is generated, and an end of a duct for discharging air is exposed through a crash pad. Also, as disclosed in Korean Patent Laid-Open No. 10-2007-0005263, not only air is blown toward the windshield (front glass) of the vehicle, but also air is blown toward the side glass, It is common to allow the glass to defrost together.

[0004] Recently, automobiles having devices such as a head-up display (HUD) have been introduced. The head-up display has been designed to project a virtual image in the visible region of the driver As the device, information (a constant speed cruise, an active cruise speed, a navigation, a traveling speed, a message, etc.) required by the driver is displayed, and in particular, this information is expressed by an image projected onto the windshield, And reduce the number of times to watch the road alternately, thereby contributing to driver's fatigue relief and driving safety.

Such a HUD apparatus is provided in the interior of the crash pad immediately in front of the driver's seat so as to irradiate the image through the upper surface of the crash pad. Accordingly, when the defroster device and the HUD device are provided together on the crash pad, the discharge port of the conventional defroster for defrosting the windshield (the first front discharge port and the second front discharge port of Korean Patent Laid-Open No. 10-2007-0005263) Is difficult to be formed at the point where the HUD device is formed (directly in front of the driver's seat). In such a case, it is not possible to remove the property at the point corresponding to the driver's seat, and the information transmission by the HUD device is hindered.

The crash pad assembly 1 according to the present invention includes a crash pad 100, a contact pad 200, a fixed panel 300, and a defroster 2.

The defroster 2 according to the present invention is used to prevent the windshield from being caught on the windshield of the vehicle and is used in combination with the crash pad 100. [

The defroster 2 includes a central duct 10, a divided duct 20, and a defrost duct 30.

The central duct 10 is located at a central portion of the defroster 2 and is provided with central openings 12a and 12b that open upward toward the center of the windshield. The central duct 10 may be divided into a first central duct 10a and a second central duct 10b.

If the first central duct 10a is biased toward the driver's seat of the vehicle, the second central duct 10b is biased toward the passenger's seat of the vehicle.

The first central duct 10a is formed with a first inlet 11a and a first central opening 12a. When the first central duct 10a forms a channel, the first inlet 11a becomes an inlet through which air is introduced and the first central opening 12a connects with the air introduced through the first inlet 11a It becomes an exit to be discharged. The first inlet 11a is connected to the air conditioner of the vehicle so that heated (or cooled) air or the like is introduced into the deep roaster 2. The first central opening 12a is exposed through the upper surface of the crash pad 100 and is engaged with the crash pad 100 at the point where the first central opening 12a is formed.

The first central duct 10a may be formed in a single channel shape. However, it is preferable that a partition wall is formed inside the first central duct 10a so as to uniformly blow air on the windshield so that a plurality of ducts are independently provided. An even air blowing can be performed in a wide area of the central part.

 The second central duct 10b is formed with a second inlet 11b and a second central opening 12b. When the second central duct 10b forms a channel, the second inlet 11b becomes an inlet through which air is introduced, and the second central opening 12b is connected to an outlet through which the air introduced through the second inlet 11b is discharged . The second inlet 11b is connected to the air conditioner of the vehicle to allow the heated air (or cooled air) or the like to flow into the deep roaster 2 and the second central opening 12b to allow the air Is exposed through the upper surface and is engaged with the crash pad 100 at the point where the second central opening 12b is formed.

The second central duct 10b may be formed in a single channel shape. However, in order to uniformly blow air on the windshield, it is preferable that a partition wall is formed therein so that a plurality of ducts are independently provided.

Both the first central opening 12a and the second central opening 12b correspond to the central opening.

The divided duct 20 is branched from the central duct 10, and a side opening 23 is formed at an end thereof. The side openings 23 are exposed through the crash pad 100, particularly at the points adjacent the side windows.

The split ducts 20 may be integral with the central duct 10, but are preferably separately manufactured and associated with the central duct 10.

The split duct 20 is a means for moving the air introduced into the inside of the vehicle in the lateral direction of the vehicle. In this case, the inlet for air inflow is not formed separately in the split duct 20 itself, Share the formed entrance. For this purpose, a partition wall 40 is formed in the central duct 10, and the partition wall 40 separates the fluid (air) flowing through the central opening and the fluid (air) moving through the divided duct 20, Let them move separately.

The divided duct 20 is divided into a first divided duct 20a and a second divided duct 20b. The first divided duct 20a branches outwardly from the first central duct 10a, The second divided duct 20b is branched outwardly from the duct 10b (in the direction opposite to the first divided duct 20a).

The first divided duct 20a branches toward the side of the vehicle, particularly toward the driver's seat, and the first side opening 23 is formed at the end of the first divided duct 20a.

The first divided duct 20a may be divided into an inner divided duct 21 and an outer divided duct 22. [ The second divided duct 20b is also divided into an inner divided duct 21 and an outer divided duct 22 and is symmetrical with the first divided duct 20a. Characteristic shapes and structures are symmetrical to each other.)

The inner split duct (21) is connected to the central duct (10) and extends toward the left or right direction.

The inner split duct 21 may be inclined or curved toward the front of the vehicle while being away from the central duct 10. That is, the inner split duct 21 is not formed parallel to the left and right direction of the vehicle but is formed in an inclined or curved shape, and can be bent toward the front side of the vehicle with respect to the central duct 10.

The outer split duct 22 extends from the end of the inner split duct 21 and is inclined or curved toward the rear of the vehicle away from the central duct 10. That is, the outer split duct 22 is also formed in an oblique or curved shape instead of being formed parallel to the left and right direction of the vehicle, but it is bent toward the rear of the vehicle from the inner split duct 21.

The overall shape of the first divided duct 20a (and the second divided duct 20b) including the inner divided duct 21 and the outer divided duct 22 is preferably a flexible curve.

By thus forming the split duct 20, it is possible to secure a space for installing a large number of other devices on the crash pad (especially on the driver's side) and to shorten the overall length of the defrost duct 30 .

A side opening 23 is formed at the end of the outer split duct 22 and the side opening 23 is exposed through the upper surface of the crash pad 100.

The defrost duct (30) is branched from the divided duct (20), and the defroster opening hole (31) is provided at the end. Particularly, the defrost duct 30 is branched on the outer split duct 22 and the defroster opening hole 31 is opened toward the lower end of the windshield.

Sectional area of the defrosting duct 30 is preferably smaller than the sectional area of the divided duct 20. [ The amount of air movement through the divided ducts 20 is greater than the amount of air moved through the defrosting ducts 30 so that the amount of air movement reduction of the divided ducts 20 by the defrosting ducts 30 is not large.

The air is discharged to the front edge of the upper surface of the crash pad 100 through the defroster opening hole 31. For this purpose, the defroster opening hole 31 is located on the left side and / or right side edge of the lower end of the windshield, (12a, 12b). That is, the center openings 12a and 12b and the defroster opening hole 31 are spaced apart from each other on the crash pad 100 and the space between the central openings 12a and 12b and the defroster opening hole 31 in the crash pad 100 Such as a HUD device.

As described above, the defroster 2 according to the present invention does not defrost the entire area of the windshield by the central openings 12a and 12b of the central duct 10, but by the central openings 12a and 12b The defrosting at the lower side of the side of the windshield is performed by the defroster opening hole 31 that branches off from the split duct 20 so that defrosting at the center of the windshield is made, A space in front of the driver's seat (and passenger's seat) can be ensured in the upper surface.

It is preferable that the defrosting duct 30 in the defroster 2 according to the present invention is made larger in cross sectional area at a point at which the defrosting hole 31 is branched from the divided duct 20. [ That is, the defrost duct 30 is formed such that the sectional area thereof increases as it is diverted from the divided duct 20 and then toward the defroster opening hole 31.

In this case, the moving speed of the air is increased from the point where the defrost duct 30 is branched from the divided duct 20 to the inside of the defrost duct 30 by the air diffusion action, 30) and induce airflow smoothly, so that the defrosting effect at the lower side of the side surface of the windshield can be enhanced.

In the crash pad assembly 1 according to the present invention, the defroster opening hole 31 may be divided into a plurality of openings, and an opening hole 31a for defining each of the defroster opening holes 31 may be formed. This opening hole 31a reinforces the rigidity in the defroster opening hole 31 and can prevent deformation (reduction in diameter, etc.) of the defroster opening hole 31 due to external force, It is possible to ensure the smooth discharge of air through the discharge port.

The crush pad 100 is formed with a center hole 110, a side hole 120 and an opening hole insertion groove 130 for discharging air through the defroster 2. The crash pad 100 is formed with a glass proximal portion 140 which is in contact with or near the windshield of the vehicle at its front end.

The center hole 110 corresponds to the center openings 12a and 12b of the defroster 2 and has a shape penetrating on the crash pad 100. [

The side holes 120 correspond to the side openings 23 of the defroster 2 and penetrate the crash pad 100.

The opening hole insertion groove 130 corresponds to the upper opening hole 320 of the fixing panel 300 to be described later and is formed on the glass adjacent portion 140 of the crash pad 100.

By thus forming the opening hole insertion groove 130 to which the upper side opening hole 320 of the fixed panel 300 is coupled to the front edge portion (the glass adjacent portion 140) of the crash pad 100, It is possible to form the opening hole inserting groove 130 while minimizing the change of the mold during the production (injection molding) of the pad 100 and also to use the large area of the crash pad 100 for the installation of other devices do.

The contact pad 200 hermetically seals between the windshield and the crash pad 100 to prevent foreign matter or noise from being generated between the two.

The contact pad 200 may be made of a material such as an elastic rubber or a foamed rubber, and is coupled to the glass adjacent portion 140, and has a substantially constant cross-sectional shape along the left and right direction.

The fixed panel 300 is fixedly coupled to the top of the defroster 2 and fixedly coupled to the bottom of the crash pad 100 and separated from the crash pad 100 to support the defroster 2, So as to be stably fixed to the crash pad 100. The fixed panel 300 may be formed by injection molding and assembled to the bottom surface of the crash pad 100.

The fixing panel 300 and the crash pad 100 may be assembled by separate fastening means (bolts, rivets, etc.), and may be formed by hooks, interference fit, or the like.

The fixed panel 300 is formed with a lower opening hole 310, an upper opening hole 320 and a first coupling surface 330 for stable coupling with the defrost duct 30 and the contact pad 200 .

The lower opening hole 310, the upper opening hole 320 and the first coupling surface 330 are formed adjacent to a point where the opening hole insertion groove 130 is formed. In particular, the upper opening hole 320, The surface 330 is configured to be inserted into the opening hole insertion groove 130 so that the first engagement surface 330 can form an extension line of the second engagement surface.

The lower side opening hole 310 is a hole that opens downward and is coupled to the defroster opening hole 31 in a communicating manner.

At this time, a sealing pad 400 may be formed for stable engagement between the lower opening hole 310 and the defroster opening hole 31. The sealing pad 400 may be made of a material capable of being elastically deformed, And can be tightly coupled to the defroster duct 30 and fixedly coupled to the lower opening hole 310.

The upper opening hole 320 communicates with the lower opening hole 310 and communicates with the upper side of the crash pad 100 so that air passing through the defroster opening hole 31 can be moved to the upper side of the crash pad 100.

The lower opening hole 310 and the upper opening hole 320 form a hole penetrating through the fixing panel 300 in the vertical direction so that the air supplied from the defrost duct 30 moves to the upper side of the crash pad 100, So that the defrosting hole 30 of the defrosting hole 31 can be stably fixed.

The first coupling surface 330 is located on the front side of the vehicle in the upper opening hole 320 and is formed to be in contact with the contact pad 200 while making a flat surface. The adhesion pad 200 may be bonded onto the first engagement surface 330 through adhesion.

A second engagement surface 141 for engagement of the adhesion pad 200 is formed to be constant along the lateral direction in the glass adjacent portion 140. The adhesion pad 200 is bonded to the second engagement surface 141).

In this way, the contact pad 200 is coupled to the crash pad 100 and the fixed panel 300 together.

The first coupling surface 330 forms an extension of the second coupling surface 141 (the second coupling surface 141 and the first coupling surface 330 form a constant plane or a constant curved surface) Are coupled to the crash pad 100 and the fixed panel 300 so that they can be coupled in a uniform form without any difference between them.

As described above, according to the defroster 2 and the crash pad assembly 1 according to the present invention, the defrost duct 30 having the defroster opening hole 31 is branched from the divided duct 20, The upper side space of the crash pad 100 is ensured so that the means other than the defroster 2 can be formed on the upper surface of the crash pad 100 while the defroster opening side holes 31 are spaced apart from each other, It is possible to easily remove the property that occurs in the case of FIG.

Also, it is possible to effectively discharge the air through the defroster opening hole 31 while allowing the fastening pad 200 to be firmly coupled to the crash pad 100 by the fixing panel 300.
