Abstract

PURPOSE:To obtain the high cleaning effect in rainy weather, etc. by installing an air stream guide body having an air stream guide surface connected to the upper surface of a deflector body onto the deflector body so as to be turned in the vertical direction of the cr body. CONSTITUTION:An elevating and lowering means 4 in a deflector body 2 pushes up an air stream guide body 3 according to a remote switch or a temperature sensor, in the necessary time, e.g, in rainy weather or traveling on a sandy road, and an air stream guide surface 30 is inclined upwardly. Therefore, the main stream (a) deflects upwardly in the rear part of a car body A, and the air sream (b) which flows along a rear window glass B is prevented from being influenced by the main flow (a), aud cleaning by the air stream (b) is carried out. In the ordinary traveling, the air sream guide body 3 is pulled down by the elevating and lowering means 4, and the lower edge is accommodated into the deflector body 2, and the air stream guide surface 30 is set horizontal, and the air resistance due to the main stream (a) is reduced. Thus, the increase of the air resistance in the ordinary traveling is suppressed, and the high cleaning effect can be obtained in the necessary time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a deflector that is attached to the rear upper end of an automobile body.

[Conventional technology]

Conventionally, the air temperature generated at the rear of the car body while driving caused dirt and dust to easily adhere to the rear surface of the car body, so
As shown in Publication No. 28, at the upper end of the rear part of the vehicle body,
A plate-shaped deflector with an airflow guiding surface was installed to direct the airflow along the rear surface of the vehicle body, thereby preventing mud and dust from adhering to the rear surface of the vehicle body.

[Problem that the invention seeks to solve]

However, as mentioned above, conventional deflectors deflect a portion of the airflow flowing above the heavy object toward the rear of the vehicle, so attempting to improve the cleaning effect of the rear of the vehicle results in increased air resistance, and vice versa. If air resistance is suppressed to a certain level, the airflow deflected by the deflector will be directed toward the airflow (mainstream) side flowing above the deflector while driving, reducing the cleaning effect, making it difficult to clean when driving in the rain or on gravel roads. There was a problem in that the cleaning effect was not exhibited when the rear view was secured, such as when driving.

[Means for solving problems]

The present invention has been made in consideration of the above-mentioned conventional problems, and includes an air flow guide surface provided at the upper end of the rear part of the vehicle body across the vehicle width direction and spaced apart from the vehicle body, and an air guide surface from the vehicle surface to the rear surface of the vehicle body. The vehicle is characterized by comprising a director main body forming a path, and an air flow guide member provided with an air flow guide surface continuous to the upper surface of the deflector main body and rotatable in the vertical direction of the vehicle body on the deflector main body. A deflector for an automobile is provided to solve the conventional problems.

[For production]

In the present invention, an air flow guide member that has a continuous air flow guide surface on the upper surface of the deflector body and is rotatable in the vertical direction of the vehicle body deflects the main flow of air toward the upper rear of the vehicle body when necessary such as when driving in the rain. This prevents the air flow flowing along the rear surface of the vehicle from being affected by the mainstream.

[Example] Next, the present invention will be described in detail based on an example shown in FIGS. 1 to 3.

In the figure, reference numeral 1 denotes a deflector located at the upper end of the rear surface of a pan-type vehicle body A. The deflector 1 has a cross section with a deflector main body 2 provided across the vehicle width direction at the upper end of the rear surface of the vehicle body, that is, at the upper end of the back door B. It consists of a substantially dogleg-shaped air flow guide body 3.

As shown in FIG. 1, the deflector main body 1 has an air flow guide surface 20 whose back surface is curved in accordance with the shape of the upper end of the back door, and is spaced apart from the upper end surface of the back door. and the upper end surface of the back door form an air flow guide path C. A part of the air flow (mainstream) a flowing above the vehicle body while the vehicle is running flows into this air flow guide path C, and the air flow is guided toward the rear window glass side.

The airflow guide 3 is located at a mounting opening 22 that is opened across the width of the vehicle at the rear of the upper surface 21 of the deflector main body 2, and rotates in the vertical direction of the vehicle via a hinge 3a provided at the internal tip. It is possible and installed. In addition, the upper surface has an air flow guide surface 3 that is continuous with the upper surface 21 of the deflector main body.
0, and the air flow guide body 3 rotates to form a deflection surface that can deflect the direction of the main Ra in a range from the rear of the vehicle body to the rear upper part of the vehicle body.

Reference numeral 4 in the figure denotes means for raising and lowering an air flow guide provided inside the deflector main body, and the raising and lowering means 4 comprises an actuator operated by a remote switch, a temperature sensor, or the like. The elevating means 4 is connected to the air flow guide 3, and when necessary, for example, in the rain or when driving on a gravel road, the actuator is extended to lift the air flow guide. When the air flow guide is pushed up, the air flow guide surface 30 is tilted and the main flow a is deflected toward the rear upper part of the vehicle body as shown in FIG. 1, and the influence of the main flow a on the air flowing along the rear window glass is Cleaning is performed by flowing air. Further, during normal running, the air flow guide 3 is lowered by the lifting means 4 and stored so that the lower end of the air flow guide 3 enters into the deflector body, and the air flow guide surface 30 is approximately horizontal. The main flow a flows toward the rear of the vehicle body in a gentle flow, and is provided so as to reduce air resistance.

〔Effect of the invention〕

As explained above, according to the present invention, since the air flow guide body having the air flow guide surface continuous to the upper surface of the deflector body is provided on the deflector body so as to be rotatable in the vertical direction of the vehicle body, When driving on a gravel road, etc., by rotating the airflow guide upward, the main stream of the airflow is deflected towards the rear upper part of the car body, and the airflow flowing along the rear of the car body is not affected by the main stream. The strong flow improves the cleaning effect and provides a high cleaning effect when needed.

In addition, by lowering the airflow guide toward the deflector body during normal driving, the main flow is not obstructed and air resistance is not increased, resulting in excellent practical effects.
