Description

[Detailed Description of the Invention] The present invention relates to an improvement of a side defroster guide provided in an automobile body.

BACKGROUND ART Conventionally, a side defroster guide provided on an automobile door is formed of a resin duct, and warm air is guided through the duct. However, since the temperature of the hot air distributed to the defroster is 80° C. to 90° C., it is necessary to use an expensive resin that is heat resistant, such as heat resistant ABS. Furthermore, since the door is made of resin, there are problems such as the inability to reinforce the door.

The present invention has been developed in view of the above-mentioned conventional problems, and is capable of not only increasing the wind speed taken into the interior of an automobile and regulating the wind speed, but also making it possible to improve It is an object of the present invention to provide a side defroster guide that can reinforce the vicinity of the base and press down the front part of the glass.

Therefore, in the present invention, the side defroster guide, which is composed of a door inner panel made of a steel plate and a defroster guide main body, is provided at the base of the door front pillar above the front of the door inner panel. A defroster duct is formed in the defroster guide, a glass holder is fixed to the surface of the defroster duct facing the door glass, and an intake port is connected to the instrument panel side duct when the door is closed on the indoor side surface. An air outlet opening toward the door glass is provided on the top surface of the defroster duct, and an air outlet is provided on the bottom surface of the defroster duct so that the cross-sectional area of the defroster duct is smaller at the air outlet than at the suction port. The desired purpose is achieved by having a structure in which an inclined portion is provided that slopes rearward and upward from the suction inlet toward the outlet.

The present invention will be described below with reference to illustrative embodiments.

A side defroster guide 11 is composed of a door inner panel 12 made of a steel plate and a defroster guide main body 13, and is provided at the base of the door front pillar 21 above the front of the door inner panel 12.

In addition, in FIG. 1, the door front pillar 21 is shown as being molded integrally with the door inner panel 12, but these may be molded separately.

The defroster guide body 13 is formed astride both the door inner panel 12 and the door front pillar 21, and its upper and lower edges are joined by welding or the like to the door inner panel 12 and the door front pillar 21, respectively, and the defroster guide body 13 is formed astride both the door inner panel 12 and the door front pillar 21. Guide body 1
3 and the door inner panel 12 form a defroster duct 20 having a substantially box-shaped closed cross section. Door glass 14 of the defroster duct 20
An elastic glass retainer 15 is fixed to the surface facing the defroster guide body 13, and an inlet 16 is formed in the door inner panel 12, which is the opposite surface facing the interior of the vehicle. ing.

When the door 1 is closed, the suction port 16 is connected to the second
It is detachably connected to the tip of the duct 17 on the side of the instrument panel 30 shown in the figure. The duct 17 is formed of rubber or resin into a bellows shape, and its base is connected to the instrument panel 30, and the duct 17 is conditioned by an air conditioner (not shown) disposed below the instrument panel 30. Air is blown out. or,
When the door 1 is opened, the suction port 16 is detached from the tip of the duct 17.

Further, a door glass 1 is provided on the upper surface of the door inner panel 12 that forms the upper surface of the defroster duct 20.
Air outlets 18 are provided that open in four directions.
19 is a defroster grill attached to the opening of the air outlet 18.

The positional relationship between the inlet 16 and the outlet 18 is as follows:
As shown in FIG. 1, an inlet 16 is formed at the lower front end of the defroster duct 20, and an outlet 18 is formed at the rear of the upper surface of the defroster duct 20.

Further, the bottom surface of the defroster guide body 13 forming the bottom surface of the defroster duct 20 is arranged so that the cross-sectional area inside the defroster duct 20 is smaller at the air outlet 18 than at the suction port 16. A sloped portion 22 that slopes rearward and upward toward the outlet 18 is provided to guide the air blown into the defroster duct 20 toward the outlet 18 .

When a force is applied to the upper part of the door 1, the stress is highest near the base of the door front pillar 21, but in the above embodiment, the side defroster guide 11 is placed near the base of the door front pillar 21, as shown in FIG. Since it is located at the base of the pillar 21, it also serves as a reinforcing member for reinforcing the door 1, and since the glass retainer 15 is fixed to the outer surface of the defroster guide body 13, the front upper part is the door front pillar 21.
The front part of the door glass 14 cut diagonally along can be held down.

As described above, according to the present invention, a side defroster guide composed of a door inner panel made of a steel plate and a defroster guide body is provided at the base of the door front pillar above the front of the door inner panel, and the side defroster guide A defroster duct is formed on the surface of the defroster duct, a glass holder is fixed on the surface of the defroster duct facing the door glass, and an inlet is provided on the indoor surface to connect with the instrument panel side duct when the door is closed, and a door is provided on the top surface. In addition to providing an air outlet opening in the direction of the glass, the bottom of the defroster duct is provided with an air outlet pointing from the inlet toward the outlet so that the cross-sectional area inside the defroster duct is smaller at the outlet than at the inlet. Since the inclined portion is provided, it is possible not only to increase the speed of the air blown into the defroster duct from the instrument panel side, but also to regulate the direction of the air.

Further, according to the present invention, since the side defroster guide made of a steel plate is provided at the base of the door front pillar, the vicinity of the base of the door front pillar can be reinforced.

Further, according to the present invention, since the glass retainer is fixed to the surface of the defroster duct facing the door glass, it is possible to prevent the door glass from swinging when the door glass is raised and lowered. .
