[0001] DEFROSTER AND CRASH PAD ASSEMBLY INCLUDING THE SAME [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a defroster and a crash pad assembly, and more particularly, to a defroster and a crash pad assembly including the same.

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.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, the well-known functions or constructions are not described in order to simplify the gist of the present invention.

1 is a perspective view showing a crash pad assembly 1 coupled with a defroster 2 according to an embodiment of the present invention. FIG. 2 is an exploded perspective view showing the crash pad assembly 1 shown in FIG. Fig. 3 is a perspective view showing the defroster 2 shown in Fig. 2, Fig. 4 is a perspective view of the defroster 2 shown in Fig. 3 from below, Fig. 5 is a perspective view of the defroster 2 shown in Fig. (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 can 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 the heated 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 conditioning system of the vehicle to allow the heated air or the like to flow into the defroster 2 and the second central opening 12b is exposed through the upper surface of the crash pad 100 And the second central opening 12b are 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 split duct (20) and has a defrost opening (31) at its end. Particularly, the defrost duct 30 is branched on the outer split duct 22 and the defrost opening 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 defrosting opening 31 is exposed through the front edge of the upper surface of the crash pad 100 (coupled to the glass proximal portion 140 of the crash pad 100) to the left and / or right edge of the lower end of the windshield 100 And are spaced apart from the central openings 12a, 12b. That is, the central openings 12a and 12b and the defrosting opening 31 are spaced apart from each other on the crash pad 100. In the space between the central openings 12a and 12b and the defrosting opening 31 in the crash pad 100, Device or the like.

As described above, the defroster 2 according to the present invention does not defrost the entire area of the windshield by the central opening of the central duct 10, but also defrosts the center of the windshield by the central opening The defrosting at the lower side of the side of the windshield is performed by the defroster opening portion 31 that branches off from the divided duct 20 to improve the defrosting efficiency and to increase the defrosting efficiency of the space in front of the driver's seat And the like.

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 where the defrosting opening 31 is branched at the defrosting opening 20 than at the point at which the defrosting opening 20 is branched. 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 defrosting opening 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.

The crash pad assembly 1 according to the present invention comprises a crash pad 100 and a defroster 2, wherein the defroster 2 can be of the type described above.

The crush pad 100 is formed with a center hole 110, a side hole 120 and a defrost hole 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 opening of the defroster 2 (position, shape, size, and the like) and penetrates 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 defrost hole 130 corresponds to the defroster opening 31 of the defroster 2 and is formed on the glass proximal portion 140 of the crash pad 100. [

By thus forming the defrost hole 130 in which the defroster opening 31 of the defroster 2 is coupled to the front edge portion (proximity portion 140 of the glass) of the crash pad 100, It is possible to form the defrost hole 130 while minimizing the change of the mold during the production (injection molding) of the crash pad 100, and also to use the large area of the crash pad 100 for the installation of other apparatuses.

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 defrost opening 31 is branched from the divided duct 20, The openings 31 are spaced apart from each other so that a space above the side surface of the crash pad 100 is secured so that means other than the defroster 2 can be formed on the upper surface of the crash pad 100, Can be easily removed.
