그 후 제2차금형상부(70a)와 제2차금형하부(70b)로 이루어진 제2차금형 내부에 제1발포체(20)와 고정사출물(40)을 삽입한다.After that, the first foam body 20 and the fixed injection material 40 are inserted into the second mold made of the second mold upper part 70a and the second mold lower part 70b.

제1발포체(20)는 고정사출물(40) 내측에 배치되어, 제1발포체(20)와 고정사출물(40) 사이에는 제2발포공간(71)이 형성된다.The first foam 20 is disposed inside the fixed injection material 40, and a second foam space 71 is formed between the first foam 20 and the fixed injection material 40.

제2발포공간(71)에 제2발포액(30a)을 주입하면, 제2발포공간(71)에는 제2발포체(30)가 형성된다.When the second foaming liquid 30a is injected into the second foaming space 71, the second foaming body 30 is formed in the second foaming space 71.

이로 인해 제1발포체(20)와 고정사출물(40)은 제2발포체(30)에 고정되게 된다.As a result, the first foam 20 and the fixed injection material 40 are fixed to the second foam 30.

그 후 제1발포체(20)의 외측 및 고정사출물(40)의 외측 일부에 접착제를 도포하여 감싸기원단(50)을 접합한다.Thereafter, an adhesive is applied to the outside of the first foam 20 and a part of the outside of the fixed injection material 40 to bond the wrapping fabric 50.

이러한 종래의 '차량용 쉬라우드의 발열장치의 제조 방법'은 발포액으로 인해 외관상에 불량이 발생할 가능성이 높고, 공정이 복잡하고, 원가가 상승한다는 문제점이 있다.Such a conventional'method of manufacturing a heat generating device for a vehicle shroud' has a problem in that there is a high possibility of occurrence of defects in appearance due to the foaming liquid, the process is complicated, and the cost is increased.

도 2에 도시된 바와 같이, 발열장치(300)는 차량용 쉬라우드(100)의 하부에 설치되어, 사용자의 하체를 가열한다.As shown in FIG. 2, the heating device 300 is installed under the vehicle shroud 100 to heat the user's lower body.

도 3에 도시된 바와 같이, 발열장치(300)는 발열장치(300)의 내측에서부터 순서대로 발열장치(300)의 형태를 잡아주는 고정사출물(330)과, 단열체(320)와, 발열체(310)와, 발열체(310) 및 고정사출물(330)을 덮는 감싸기원단(340)으로 구성된다. As shown in FIG. 3, the heating device 300 includes a fixed injection object 330 that holds the shape of the heating device 300 in order from the inside of the heating device 300, a heat insulating body 320, and a heating element ( 310), and a heating element 310 and a wrapper fabric 340 covering the fixed injection material 330.

이하에서는 도 4를 참조하여, 차량용 쉬라우드의 발열장치에 대해 서술하기로 한다.Hereinafter, with reference to FIG. 4, a heating device for a vehicle shroud will be described.

발열체(310)는 복수의 발열사(311)가 일정 간격 이격되어 부직포(312)에 재봉되도록 형성된다.The heating element 310 is formed so that the plurality of heating threads 311 are spaced apart from each other at a predetermined interval to be sewn on the nonwoven fabric 312.

이 때, 발열사(311)는 발열사(311)의 직경 일부가 부직포(312)에 최대한 파묻히도록 재봉된다.At this time, the heating thread 311 is sewn so that a part of the diameter of the heating thread 311 is buried in the nonwoven fabric 312 as much as possible.

이로 인해 발열사(311)로 인해 발열체(310)의 외측면에 형성되는 요철의 높낮이 차가 적어지고, 사용자가 상기 요철을 감지하기 어려워진다.Accordingly, the difference in height of the irregularities formed on the outer surface of the heating element 310 due to the heating thread 311 is reduced, and it is difficult for the user to detect the irregularities.

발열체(310)의 양측에는 음극단자(313)와 양극단자(14)가 형성되어, 발열사(311)에 전기가 통할 수 있도록 한다.A negative terminal 313 and a positive terminal 14 are formed on both sides of the heating element 310 to allow electricity to pass through the heating thread 311.

단열체(320)는 단열이 되는 재질로 형성되어, 발열체(310)에서 발생한 열이 후술할 고정사출물(330)에 전달되지 않게 한다.The heat insulator 320 is formed of a heat-insulating material so that heat generated from the heating element 310 is not transferred to the fixed injection material 330 to be described later.

고정사출물(330)에는 발열체(310)와, 단열체(320)가 삽입될 수 있도록 요홈이 형성된다.A recess is formed in the fixed injection material 330 so that the heating element 310 and the heat insulator 320 can be inserted.

감싸기원단(340)은 고정사출물(330)의 요홈을 덮을 수 있을만큼 충분히 크게 형성된다.The wrapping fabric 340 is formed large enough to cover the groove of the fixed injection material 330.

감싸기원단(340)의 두께는 부직포(312) 위로 돌출된 발열사(311)의 직경 일부가 감싸기원단(340)에 파묻히도록 충분히 두껍게 형성된다.The thickness of the wrapping fabric 340 is formed to be sufficiently thick so that a part of the diameter of the heating yarn 311 protruding above the nonwoven fabric 312 is buried in the wrapping fabric 340.

이로 인해 사용자는 감싸기원단(340)의 외측을 통해 발열사(311)에 의해 형성되는 요철을 감지하기 어려워진다.For this reason, it becomes difficult for the user to detect the irregularities formed by the heating yarn 311 through the outside of the wrapping fabric 340.

이하에서는 도 4를 참조하여, 차량용 쉬라우드의 발열장치의 제조 방법을 서술하기로 한다.Hereinafter, a method of manufacturing a heating device for a vehicle shroud will be described with reference to FIG. 4.

우선, 단열체(320)의 하면에 제2접착제(325)를 접착한다.First, a second adhesive 325 is adhered to the lower surface of the heat insulator 320.

제2접착제(325)는 본드로 구비될 수 있다.The second adhesive 325 may be provided as a bond.

제2접착제(325)는 단열체(320) 하면의 가장자리에 접작된다The second adhesive 325 is attached to the edge of the lower surface of the heat insulator 320

제2접착제(325)에 의해 단열체(320)의 하면은 고정사출물(330)의 요홈의 바닥에 고정된다.The lower surface of the heat insulating body 320 by the second adhesive 325 is fixed to the bottom of the groove of the fixed injection material 330.

그 다음, 발열체(310)의 하면에 제1접착제(315)를 접착한다.Then, the first adhesive 315 is adhered to the lower surface of the heating element 310.

발열체(310)의 하면은 발열사(311)가 재봉되지 않는 쪽인 것이 바람직하다.It is preferable that the lower surface of the heating element 310 is the side where the heating thread 311 is not sewn.

제1접착제(315)는 양면테이프로 구비될 수 있다.The first adhesive 315 may be provided with double-sided tape.

제1접착제(315)는 발열체(310) 하면의 가장자리를 따라 접착된다.The first adhesive 315 is adhered along the edge of the lower surface of the heating element 310.

제1접착제(315)에 의해 발열체(310)의 하면은 단열체(320)의 상면에 고정된다.The lower surface of the heating element 310 is fixed to the upper surface of the heat insulator 320 by the first adhesive 315.

그 후, 발열체(310)의 상면 및 고정사출물(330)의 상부에 제3접착제(미도시)를 도포한다.After that, a third adhesive (not shown) is applied to the upper surface of the heating element 310 and the upper surface of the fixed injection material 330.

상기 제3접착제에 의해, 감싸기원단(340)은 발열체(310)의 상면 및 고정사출물(330)의 상부를 덮도록 고정된다. 즉, 고정사출물(330)의 요홈은 감싸기원단(340)으로 덮이게 된다.By the third adhesive, the wrapping fabric 340 is fixed to cover the upper surface of the heating element 310 and the upper surface of the fixed injection material 330. That is, the groove of the fixed injection material 330 is covered with the wrapping fabric 340.

이로 인해 발열체(310), 단열체(320), 고정사출물(330) 및 감싸기원단(340)은 별도의 발포 공정 없이 서로 접합되어 고정될 수 있다.Accordingly, the heating element 310, the heat insulator 320, the fixed injection material 330, and the wrapping fabric 340 may be bonded and fixed to each other without a separate foaming process.

도 4에는 발열체(310)와 단열체(320) 사이와, 단열체(320)와 고정사출물(330) 사이에 일정한 공간이 존재하는 것처럼 도시되어 있으나, 이는 이해를 돕기 위해 음극단자(313), 양극단자(314), 제1접착제(315) 및 제2접착제(325)의 두께를 과장되게 도시했기 때문이다.In FIG. 4, a certain space exists between the heating element 310 and the heat insulator 320, and between the heat insulator 320 and the fixed injection material 330, but this is a negative terminal 313, This is because the thicknesses of the anode terminal 314, the first adhesive 315, and the second adhesive 325 are shown exaggeratedly.

실제로는 음극단자(313), 양극단자(314), 제1접착제(315) 및 제2접착제(325)의 두께가 얇기 때문에, 도 3에 도시된 바와 같이, 발열체(310)와 단열체(320) 사이 및 단열체(320)와 고정사출물(330) 사이에는 공간이 거의 존재하지 않도록 형성된다.Actually, since the thickness of the negative electrode terminal 313, the positive terminal 314, the first adhesive 315, and the second adhesive 325 is thin, as shown in FIG. 3, the heating element 310 and the heat insulator 320 ) And between the heat insulating body 320 and the fixed injection material 330 is formed so that there is almost no space.

상술한 바와 같이, 본 발명의 바람직한 실시예를 참조하여 설명하였지만, 해당기술분야의 당업자는 특허 청구범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 내에서 본 발명을 다양하게 수정 또는 변형하여 실시할 수 있다.As described above, although it has been described with reference to a preferred embodiment of the present invention, those skilled in the art will perform various modifications or variations of the present invention without departing from the spirit and scope of the present invention described in the claims.
