Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air outlet structure for air conditioning in a vehicle.

[0002]

[Prior Art]

 FIG. 5 shows an example of a conventional air-conditioning air outlet structure, in which an air outlet member 52 is attached to the opening of an instrument panel 51 which is an interior component, and the air outlet 53 is vertically rectified. , And fins 55 for rectifying in the left-right direction are incorporated. Reference numeral 56 is a rectifying knob in the vertical direction, 57 is a rectifying dial in the horizontal direction, and 58 is an air-conditioning duct opening / closing lever.

[0003]

[Problems to be solved by the device]

 As described above, in the conventional structure, the rectifying fins are exposed even when the air conditioner is not used, and the degree of freedom in design is low. Also, since the fins and other parts are always exposed, dirt such as dust easily collects and is difficult to clean. Further, since the fins are used for rectifying in the vertical direction and the horizontal direction, and the resistance of the outflow air is large, a sufficient amount of blowout cannot be obtained. Also, since the upper and lower and left and right wind directions are adjusted with fins, there were restrictions on the blowing direction.

Therefore, the object of the present invention is to improve the appearance and the degree of freedom in design, facilitate cleaning, increase the degree of freedom in the air discharge direction, and facilitate the control of the blown air volume. The purpose of this is to provide a vehicle air conditioning outlet structure that can also reduce the resistance of the vehicle.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has a structure of an air-conditioning outlet provided in an opening formed in an interior part of a vehicle, in which at least part of the periphery of the interior part is blown with air. It is characterized in that it has an outlet cap with an outlet that can be retracted and rotatably installed. Specifically, the outlet cap is capable of projecting and retracting in the vertical direction, and the air outlet is provided with fins for rectifying only in the vertical direction.

[0006]

[Action]

 First, since it is an outlet cap that has an air outlet around it and can be retracted, the outlet cap can be pushed into the opening when it is not in use, improving the appearance and flexibility of the design and making cleaning easier. And since it is a rotatable outlet cap, the degree of freedom is high with the air exhaust direction being 360 ° in all directions, and the outlet air volume can be controlled easily by operating the outlet cap in the vertical direction. Further, the air outlet around the outlet cap only needs to be provided with fins for rectifying only in the vertical direction, so that the resistance of the outflowing air is also reduced.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, which shows an example of a usage state of the air conditioning outlet structure of the present invention, 1 is an instrument panel which is an interior part, and 11 is an outlet cap. As shown in FIGS. 2 and 3, an opening 2 is formed on the upper surface of the instrument panel 1, and the air-conditioning duct 3 arranged inside the instrument panel 1 has a cylindrical shape attached to the opening 2. It is connected to the holder 4.

The cylindrical holder 4 is provided with a flange portion 5 that overlaps the upper surface of the instrument panel 1, and the inner peripheral side of the upper surface of the flange portion 5 is formed into a tapered surface 6. An outlet cap 11 is incorporated in the cylindrical holder 4 so as to be vertically retractable as indicated by an arrow B in FIG. 1 and rotatably in a lateral direction as indicated by an arrow C.

The outlet cap 11 is formed by integrally forming a cylindrical portion 12 and an upper wall portion 13. An air outlet 14 is formed around the cylindrical portion 12, and an air outlet 14 is formed in the air outlet 14. , A plurality of movable fins 15 that perform rectification only in the vertical direction are attached. The upper wall portion 13 has a curved upper surface and a flange portion 16. The lower surface side of the flange portion 16 is formed into a tapered surface 17.

A guide cylinder 8 is provided in the cylindrical holder 4, and an outlet cap 11 is fitted in the guide cylinder 8 in a cylindrical portion 12 so as to be vertically slidable and horizontally rotatable. . Further, as shown in FIG. 4, a plurality of ring-shaped recesses 7 ..., 7 ... Are formed in the circumferential direction above and below the inner circumference of the cylindrical holder 4, and the upper and lower sides of the guide cylinder 8 correspond to each other. .., 9 ... are formed.

Balls 21 ..., 21 ... that can project inward from the guide cylinder 8 from inside the upper and lower storage holes 9, ..., 9 are provided, and the balls 21. The springs 22 ..., 22 ... Provided in the recesses 7 ... On the other hand, an annular ball engaging groove 18 is formed in the lower peripheral portion of the cylindrical portion 12 of the outlet cap 11, and the balls 21 ... The immersion state shown in 2 and the protruding state shown in FIG. 3 are maintained.

According to the air conditioning outlet structure having the above configuration, the following advantages can be obtained as compared with the conventional structure. That is, first, when not in use, as shown in FIG. 2, by immersing the outlet cap 11 in the instrument panel 1, the appearance is improved and the area around the instrument panel 1 is easily cleaned. Become.

In use, as shown in FIGS. 1 and 3, the outlet cap 11 is projected onto the instrument panel 1 so that the air outlet 14 of the cylindrical portion 12 is oriented in all directions of 360 °. And the amount of air blown out from the air outlet 14 can be changed by changing the amount of protrusion of the cylindrical portion 12. Further, the air outlet 14 need only be provided with the movable fins 15 for rectifying only in the vertical direction, and it is not necessary to provide fins for rectifying in the horizontal direction. Therefore, the resistance of the air flowing out from the air outlet 14 It will be low.

The outlet cap may be configured to be electrically operated by using an actuator such as a motor, or may be a push-up type that pops out when pushed by hand. Further, a plurality of air outlets may be provided around the outlet cap, and further, the specific location, the detailed structure, the shape, etc. can be appropriately changed other than the embodiment. .

[0015]

[Effect of the device]

 As described above, according to the air conditioning outlet structure of the present invention, since the outlet cap having the air outlet in at least a part of the periphery is rotatably and rotatably incorporated in the opening of the interior component, It is possible to improve the external appearance and the degree of freedom in design during use, make cleaning easier, and increase the degree of freedom in the direction of air discharge, as well as the control of the blown air volume. Further, the resistance of the outflowing air can be reduced only by providing the fins for rectifying only in the vertical direction at the air outlet around the outlet cap.
