Description

레이더 전파 투과형 커버{Radio Wave Penetration Cover}Radar Wave Penetration Cover {Radio Wave Penetration Cover}

본 발명은 스마트 크루즈 컨트롤(SCC; Smart Cruise Control)에 사용되는 레이더 전파 투과형 커버에 관한 것이다.The present invention relates to a radar transmission type cover used in a smart cruise control (SCC).

스마트 크루즈 컨트롤(SCC; Smart Cruise Control)이란 레이더 센서를 이용하여 전방 차량을 감지하여 선행 차량이 존재하면 선행 차량과의 특정 거리를 유지하며 주행하는 추종 기능과 선행 차량이 존재하지 않으면 특정 속도로 주행하는 설정 속도 주행 기능을 모두 갖춘 크루즈 컨트롤(Cruise Control)의 발전된 형태이다.Smart cruise control (SCC) uses a radar sensor to detect a vehicle in front and maintains a specific distance from the preceding vehicle when there is a preceding vehicle, and drives at a specific speed when there is no preceding vehicle. It is an advanced form of cruise control with all set speed driving functions.

스마트 크루즈 컨트롤는 적응적 크루즈 컨트롤(ACC: Adaptive Cruise Control)이라고도 한다.Smart cruise control is also called adaptive cruise control (ACC).

스마트 크루즈 컨트롤은 엔진 제어 유닛과 전자식 제동 유닛을 이용하여 차량의 가감속을 자동화하여 운전자의 편의성 향상과 더불어 전방 충돌의 위험 또한 감소할 수 있는 효과를 지닌 대표적인 운전자 보조/지원 시스템이다.Smart cruise control is a representative driver assistance/assistance system that uses the engine control unit and electronic braking unit to automate the acceleration and deceleration of the vehicle, thereby improving the driver's convenience and reducing the risk of forward collision.

이러한 시스템의 핵심이 되는 SCC 레이더는 차량의 전방 중앙에 설치하는 것이 성능 확보 측면에서 가장 유리한데, 이러한 차량 전방 중앙에는 통상적으로 라디에이터 그릴이나, 자동차 제조 회사의 앰블럼 또는 장식물 등이 위치하는 경우가 많다.It is most advantageous to install the SCC radar, which is the core of such a system, in the front center of the vehicle in terms of securing performance, and in the center of the front of the vehicle, a radiator grill or an automobile manufacturer's emblem or decoration is usually located in many cases. .

일반적으로 라디에이터 그릴은 금속 또는 플라스틱으로 제조되고, 크롬으로 다시 도금을 하여, 외부의 환경으로부터 발생하는 부식을 방지하게 된다.In general, a radiator grill is made of metal or plastic, and plated with chrome again to prevent corrosion from external environments.

그러나 금속은 전파 투과성이 낮기 때문에 SCC 레이더의 전파 송수신에 악영향을 미치게 된다.However, since metal has low radio wave permeability, it adversely affects radio wave transmission and reception of SCC radar.

따라서, 전파 송수신이 원활하게 이루어질 수 있도록 라디에이터 그릴의 일부 영역을 별도의 레이더 커버로 대체하여 전파 투과성을 확보하는 방법이 시도되어 왔다.Therefore, a method of securing radio wave transmittance by replacing a partial area of the radiator grill with a separate radar cover has been attempted so that radio wave transmission and reception can be performed smoothly.

한국 등록특허공보 제2018-0055983호(이하 종래기술 1)은 차량용 전파 투과 부재 제조방법에 관한 것이다.Korean Patent Publication No. 2018-0055983 (hereinafter referred to as prior art 1) relates to a method of manufacturing a radio wave transmitting member for a vehicle.

종래기술 1의 배경기술에 언급된 바와 같이, 전파 투과 부재(10)는 기재층(1) 표면의 적어도 일부에 금속층(2)을 증착한 다음, 플라스틱 부재의 커버층(3)을 사출하여, 기재층(1) 및 커버층(3)이 접합된 형태로 형성하게 된다. As mentioned in the background art of the prior art 1, the radio wave transmitting member 10 is formed by depositing a metal layer 2 on at least a part of the surface of the base layer 1, and then injecting the cover layer 3 of the plastic member, The base layer 1 and the cover layer 3 are formed in a bonded form.

한국 등록특허공보 제1,913,941호(이하 종래기술 2)은 이중 사출 시 발생하는 열에 의해 도료 변색이 발생하고, 사출 커버와 몰드 베이스가 일체로 형성되기 때문에 불량 발생 시 제품의 재활용이 불가하고, 폐기해야 하는 문제점을 개선하기 위해 제안된 것으로, 커버 부재와 몰드 베이스를 별도로 제조한 후, 체결하는 방식이다.In Korea Patent Publication No. 1,913,941 (hereinafter referred to as prior art 2), paint discoloration occurs due to heat generated during double injection, and because the injection cover and the mold base are integrally formed, the product cannot be recycled in case of defects and must be discarded. This is a method that has been proposed to improve the problem that the cover member and the mold base are separately manufactured and then fastened.

선행문헌인 종래기술 1과 종래기술 2는 SCC 레이더 커버로서의 자체기능을 충실히 수행할 수 있으나, SCC 레이더 커버의 심미성 등의 측면에서 다소 밋밋하다는 불만이 제기되어 왔다.Although prior art 1 and prior art 2 can faithfully perform their function as an SCC radar cover, complaints have been raised that the SCC radar cover is rather plain in terms of aesthetics and the like.

또한, SCC 레이더 커버의 작동 여부를 쉽게 인식하기 어렵다는 불만도 제기되어 왔다.In addition, complaints have been raised that it is difficult to easily recognize whether the SCC radar cover is in operation.

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시 예를 상세히 설명하기로 한다. 이에 앞서, 본 명세서 및 청구범위에 사용된 용어나 단어는 통상적이거나 사전적인 의미로 한정해서 해석되어서는 아니 되며, 발명자는 그 자신의 발명을 가장 최선의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의할 수 있다는 원칙에 입각하여, 본 발명의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다.Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms or words used in the present specification and claims should not be construed as being limited to their ordinary or dictionary meanings, and the inventor should properly understand the concept of the term in order to best describe his invention. Based on the principle that can be defined, it should be interpreted as meaning and concept consistent with the technical idea of the present invention.

레이더 전파 투과형 커버(1)에 사용되는 필름 레이어는 다음과 같이 이루어진다.The film layer used in the radar radio wave transmission type cover 1 is made as follows.

메인 필름층(300)의 재질은 PET이다.The material of the main film layer 300 is PET.

메인 필름층(300)의 상면에는 인쇄층(320)이 형성되며, 인쇄층(320)을 보호하기 위한 인쇄 보호층(340)이 차례로 적층된다.A printed layer 320 is formed on the upper surface of the main film layer 300 , and a printed protective layer 340 for protecting the printed layer 320 is sequentially stacked.

메인 필름층(300)의 상면의 인쇄층(320)은 자동차의 엠블럼을 나타낸다.The printed layer 320 on the upper surface of the main film layer 300 represents the emblem of a vehicle.

메인 필름층(300)의 배면에는 빛투과 방지 인쇄층(350)이 형성된다.A light transmission preventing printing layer 350 is formed on the rear surface of the main film layer 300 .

이때 빛투과 방지용 인쇄층(350)은 메인 필름층(300)의 배면 전부를 덮도록 형성하지 않고 메인 필름층(300)의 배면 일부가 노출되도록 틈을 형성하는 것이 바람직하다.In this case, the light transmission preventing printing layer 350 is not formed to cover the entire rear surface of the main film layer 300, but it is preferable to form a gap so that a portion of the rear surface of the main film layer 300 is exposed.

본 발명의 바람직한 제1실시례에서는 이러한 틈을 빛투과 방지 인쇄층 미형성부(360)라 정의한다.In the first preferred embodiment of the present invention, such a gap is defined as the light transmission preventing printed layer non-formed portion 360 .

본 발명의 바람직한 제1실시례는 다음과 같다.A first preferred embodiment of the present invention is as follows.

먼저 수지로 이루어지는 제1커버부재(100) 내지 제3커버부재(200)를 포함한다.First, it includes a first cover member 100 to a third cover member 200 made of resin.

제1커버부재(100)와 제3커버부재(200)는 PC 수지로 이루어진다.The first cover member 100 and the third cover member 200 are made of PC resin.

제2커버부재(150)는 ASA 수지 등 불투명한 수지를 사용한다.The second cover member 150 uses an opaque resin such as ASA resin.

제1커버부재(100)와 제2커버부재(150) 사이에는 메인 필름층(300)이 구비된다.A main film layer 300 is provided between the first cover member 100 and the second cover member 150 .

메인 필름층(300)의 상면에는 인쇄층(320)과 인쇄층(320)을 덮는 인쇄 보호층(340)이 적층되어 형성된다.A printing layer 320 and a printing protection layer 340 covering the printing layer 320 are laminated on the upper surface of the main film layer 300 .

메인 필름층(300)의 배면에는 빛투과 방지 인쇄층(350)이 도포된다.On the rear surface of the main film layer 300 , a light transmission preventing printing layer 350 is applied.

바람직하게는 인쇄층의 테두리(330)를 따라 빛투과 방지 인쇄층(350)이 도포되지 않는 틈이 형성하는 것이 좋다.Preferably, a gap is formed along the edge 330 of the printed layer to which the light transmission preventing printing layer 350 is not applied.

이러한 틈을 빛투과 방지 인쇄층 미형성부(360)라 정의한 바 있다.Such a gap has been defined as the non-formed portion 360 of the light transmission preventing printed layer.

이때 메인 필름층(300)과 제2커버부재(150)의 사이에는 제3커버부재(200)가 형성된다.At this time, a third cover member 200 is formed between the main film layer 300 and the second cover member 150 .

제3커버부재(200)는 후술하는 LED 조명(400)의 빛을 안내하는 도광판 역할을 한다.The third cover member 200 serves as a light guide plate for guiding the light of the LED lighting 400 to be described later.

본 발명의 제2실시례에서는 메인 필름층(300)과 제2커버부재(150) 사이에 LED 조명(400)이 위치한다.In the second embodiment of the present invention, the LED lighting 400 is positioned between the main film layer 300 and the second cover member 150 .

LED 조명(400)의 빛은 불투명한 ASA 재질의 제2커버부재(150)는 투과하지 못한다.The light of the LED lighting 400 does not pass through the second cover member 150 made of an opaque ASA material.

따라서, 레이더 전파 투과형 커버(1)의 후방을 향해서는 LED 조명(400)이 투과되지 못한다.Therefore, the LED light 400 is not transmitted toward the rear of the radar wave transmission type cover (1).

그러나, 제2커버부재(150)보다 전방에 위치한 제3커버부재(200)는 투명한 PC 재질로 이루어져 있으므로, LED 조명(400)의 빛을 투과시킬 수 있다.However, since the third cover member 200 positioned in front of the second cover member 150 is made of a transparent PC material, it is possible to transmit the light of the LED lighting 400 .

제3커버부재(200)를 투과한 빛은 빛투과 방지 인쇄층 미형성부(360)을 투과한 후, 메인 필름층(300)을 투과하여, PC 재질로 이루어진 제1커버부재(100)를 투과한다.The light that has passed through the third cover member 200 passes through the light transmission preventing printed layer non-formed part 360, then passes through the main film layer 300, and passes through the first cover member 100 made of a PC material. do.

즉, 메인 필름층(300)과 제2커버부재(150) 사이에서 LED 조명(400)의 빛은 불투명한 ASA 재질의 제2커버부재(150)가 있는 후방으로는 투과되지 못하며, 투명한 PC 재질로 이루어진 제1커버부재(100)와 제3커버부재(200)를 투과한 후 전방으로 조사된다.That is, between the main film layer 300 and the second cover member 150, the light of the LED lighting 400 is not transmitted to the rear with the second cover member 150 made of an opaque ASA material, and is made of a transparent PC material. After penetrating the first cover member 100 and the third cover member 200 made of , it is irradiated forward.

본 발명의 제3실시례에서는 LED 조명(400)이 제2커버부재(150)의 내측 테두리를 따라 형성할 수 있다.In the third embodiment of the present invention, the LED lighting 400 may be formed along the inner edge of the second cover member 150 .

레이더 전파 투과형 커버는 외관이 밋밋한 기존의 SCC 레이더 커버에 라이팅 기능을 부여하여 심미성을 강화할 수 있을뿐만 아니라, 레이더 커버에 부여된 라이팅 기능과 SCC 레이더 작동을 연동시켜, 외부에서 SCC 레이더 작동 여부를 용이하게 알 수 있다.The radar transmission type cover not only enhances aesthetics by giving a lighting function to the existing SCC radar cover, which has a plain appearance, but also facilitates the operation of the SCC radar from the outside by linking the lighting function given to the radar cover and the operation of the SCC radar. can be known
