Description

[Detailed description of the invention] (Field of industrial application) This invention is a register structure for a vehicle air conditioner, specifically, a vehicle air conditioner that is rotatably mounted on the installation opening of the instrument panel to which an air duct is connected. Concerning register structure.

(Prior art) Conventionally, as this type of register structure, for example,
As described in Japanese Patent Application No. 57-97712, a wind direction adjusting fin is installed in a register body having a generally rectangular shape so as to be able to swing freely, and the conditioned air is blown out from the outlet of the register body by swinging of the adjusting fin. A device in which the blowing direction of the air is adjusted is known.

By the way, the register structure lacks novelty in design and has a bad appearance. Therefore, the register body is made circular, and the register body is rotatably attached to the mounting opening of the instrument panel.
They developed a register structure in which the angle of the wind direction adjustment fins built into the main body is changed by rotating the main body of the register, thereby adjusting the blowing direction of conditioned air.

However, in a register structure in which the register main body is circular and is rotatably attached to the instrument panel, in order to regulate the rotational position of the register main body, in other words, adjustment fins installed in the main body are adjusted to a predetermined adjustment angle. In order to maintain the resistance, it is necessary to provide a sliding resistance between the register body and the instrument panel to give the register body a sense of moderation. The idea was to interpose a separately formed spring material between the register body and the register body, and use the spring material to provide sliding resistance to the register body, thereby giving the body a sense of moderation.

(Problem to be solved by the invention) However, in the above register structure, a spring material is separately formed in order to provide sliding resistance to the register main body, and the spring material is connected between the register main body and the instrument panel. Since the parts are interposed in between, there is a possibility that the number of parts not only increases, but also increases production costs.

The present invention was devised in view of the above-mentioned problems, and its purpose is to apply sliding resistance to the resistor body using the air duct connected to the instrument panel, thereby improving the resistance of the parts. To provide a register structure that can reduce the number of points and reduce production costs.

(Means for Solving the Problems) In order to achieve the above object, the present invention forms an engaging portion 8 extending in the circumferential direction radially outward of the connection port 1a formed in the instrument panel 1. At the same time, an engaging claw 7 is formed on the register body 5 to engage with the engaging portion 8 and prevent the engaging claw 7 from detaching from the instrument panel 1.
The register main body 5 is rotatably and irremovably supported by the instrument panel 1 by engagement with the engaging portion 8, while the air duct 3 is formed of an elastic material, and the opening of the air duct 3 is provided with:
The register body 5 is interposed between a peripheral edge of the instrument panel 1 located radially outward of the connection port 1a and the register main body 5 facing the peripheral edge of the instrument panel 1. A protrusion 9 is formed that urges the cylindrical body outward.

(Function) Thus, the protrusion of the air duct applies sliding resistance to the register body, giving a sense of moderation to the register body, and making it possible to regulate the register body to a predetermined rotational position.

(Example) The register structure of a vehicle air conditioner according to the present invention will be described below with reference to an example shown in the drawings.

In the figure, 1 is an instrument panel installed on the front side of the vehicle, and a connection port 1 is opened in a circular shape in the panel 1.
