And more particularly, to a rotatable shield of an adaptive headlight lamp system that prevents thermal deformation of units disposed in the periphery of the rotatable shield by blocking conduction of heat generated by a focus formed on the rotatable shield.

Generally, the vehicle is provided with a lighting function so that the driver can see objects in the driving direction at night while driving, and an equalizing device is provided to notify other vehicles or other road users of the driving condition of the vehicle. For example, headlamps and fog lights among a variety of vehicle lamps are aimed at lighting functions, and turn signal lamps, brake lights and car lights etc. are aimed at signal functions.

Among these, the vehicle headlamp has an essential function of securing the driver's view at night by irradiating light in the running direction of the vehicle. The conventional vehicle headlamp has a fixed light irradiation direction. Since the light irradiation direction is fixed, it is difficult to ensure the driver's view when the vehicle enters the straight road from the straight road, and it is difficult to secure the driver's view continuously even with the curved road.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to clarify the solution to the technical problem of the present invention. In the following description of the present invention, however, the description of related arts will not be repeated unless the gist of the present invention is obscured. In addition, the terms described below are defined in consideration of the functions of the present invention, and may be changed depending on the intention or custom of the designer, the manufacturer, and the like. Therefore, the definition should be based on the contents throughout this specification. In addition, parts denoted by the same reference numerals throughout the specification represent the same elements.

Hereinafter, the rotary type shield 1 of the adaptive headlight system according to the present invention will be described.

4 to 6, the rotatable shield 1 of the adaptive headlight system according to the present invention includes a main body 100, a projection 200 including a high heat source region T1 in which a focal point is formed, (300) and a heat damper (310).

The main body 100 is rotated by a predetermined angle about the axis of the rotary shaft 300 so that a beam pattern is formed according to the shape of each projection 200 formed on the outer peripheral surface of the main body 100.

As shown in FIGS. 4 and 5, the main body 100 has a semi-cylindrical shape having a horizontal surface with respect to the shaft along the longitudinal direction on one side, and includes an outer peripheral surface 110 and an inner peripheral surface 120 along the circumferential direction of the shaft. . The main body 100 includes the conductive parts 130 at both ends in the longitudinal direction so that the rotary shaft part 300 is installed.

Referring to FIG. 4, a plurality of protrusions 200 protruding vertically along the longitudinal direction of the main body 100 are formed on the outer circumferential surface 110 of the main body 100.

Further, as shown in Fig. 5, the main body 100 includes an inner circumferential surface 120 formed concavely in the longitudinal direction along the circumferential direction of the shaft. 5, an inner circumferential surface 120 is formed on the other side of the main body 100 facing the outer circumferential surface 110 of the main body 100 on which the protrusions 200 are formed. The main body 100 may include a lightening groove 140 formed by the inner circumferential surface 120 and the conductive portion 130.

Accordingly, since the light-weighted groove 140 is formed in the main body 100, the rotatable shield 1 of the adaptive headlight system according to the present invention can be lightened by weight reduction, It is possible.

Here, the shape of the inner circumferential surface 120 is not limited to the shape of a semicircular column formed in the longitudinal direction along the circumferential direction of the shaft as described above. The shape of the inner circumferential surface 120 is not limited to the shape of the semi- And may be formed in various shapes for heat transfer (radiation, convection, etc.). It is needless to say that grooves or protrusions may be formed on the inner circumferential surface 120 of the main body 100 in order to facilitate the transfer of heat conducted from the heat source region T1 (radiation, convection, etc.).

The rotary shaft portion 300 is vertically protruded from opposite ends of the body 100 in the longitudinal direction, that is, from the conductive portion 130. Accordingly, the main body 100 can be rotated in accordance with the rotation of the rotary shaft portion 300 about the axis of the rotary shaft portion 300.

6, the heat damper 310 is provided so as to protrude from the outer circumference of the rotary shaft portion 310, so that heat is generated between the heat damper 310 and the rotary shaft portion 310, A difference in contact area occurs.

Accordingly, during the thermal conduction from the high heat source area T1 to the low heat source area T2, the heat damper 310 reduces the heat transfer area, that is, the heat contact area, of heat transmitted to the rotary shaft part 300, T2). ≪ / RTI >

4 to 5, the conductive portion 130 of the rotatable shield 1 of the adaptive headlight system according to the present invention is formed with a heat conduction hole 150 in communication with the lightening groove 140 .

The heat conduction prevention hole 150 is formed in the conductive portion 130 disposed between the main body 100 and the rotary shaft portion 300 so that the heat conduction from the high heat source region T1 to the rotary shaft portion 300 can be suppressed .
