Description

자동차용 후방 물체 식별 경보 시스템의 센서고정용 홀더{Senser fixing folder of alarm system to discern the object in back for automobile}Sensor fixing folder of alarm system to discern the object in back for automobile}

본 발명은 자동차의 후미 범퍼에 설치되어 후방 물체를 감지해 차의 충돌을 방지하는 후방 물체 식별 경보 시스템(BWS:back warring sensor)에 있어서, 센서를 범퍼에 고정하는 센서 고정용 홀더에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sensor holder for fixing a sensor to a bumper in a rear object identification warning system (BWS) installed in a rear bumper of a vehicle to detect a rear object to prevent a collision of a vehicle.

일반적으로 후방 물체 식별 경보 시스템은 초음파로 작동되며 각 센서는 송신기와 수신기의 역할을 겸하고 있다.Typically, the rear object identification alarm system is ultrasonically operated, with each sensor acting as a transmitter and a receiver.

작동 과정을 살펴보면, 우선 센서가 송신기로 초음파를 쏘고 장애물에 부딪혀 돌아오는 초음파를 다시 수신기로 변한 센서가 받아들이고 그 시간 차이를 계산하여 거리를 측정하는 것이다.In the operation process, first, the sensor shoots the ultrasonic wave with the transmitter, and the sensor that receives the ultrasonic wave that hits the obstacle is returned to the receiver and calculates the time difference to measure the distance.

상기와 같이 종래에는 후방 물체 식별 경보 시스템에 있어서, 센서를 자동차의 범퍼에 홀더를 이용하여 고정하였다.As described above, in the rear object identification alarm system, a sensor is fixed to a bumper of a vehicle by using a holder.

그러나 종래에 사용되어온 홀더는 센서가 조립되는 홀의 형상이 동일하고 홀더 제작시 사이드 게이트를 이용하여 제작하였다.However, the holders used in the related art have the same shape of the hole in which the sensor is assembled, and the holder is manufactured by using a side gate.

상기와 같이 종래에 사용되어온 홀더는 사이드 게이트 방식으로 제작함으로 써 웰드라인의 발생이 심하여 품질을 저하시키는 중요한 요인이 되었으며, 웰드라인 발생으로 인하여 제품이 수축이 일어나는 등의 문제점이 있다.As described above, the holder used in the related art is a significant factor in reducing the quality due to the severe generation of the weld line by manufacturing the side gate method, and there is a problem such that the product shrinks due to the weld line generation.

이와 같이 홀더에 웰드 라인이 발생하게 되면 웰드 라인이 클랙과 같이 보여 외관상 좋지 않고, 웰드부에서 기계적 강도가 저하되는 단점이 있다.As such, when the weld line is generated in the holder, the weld line looks like a crack, which is not good in appearance, and has a disadvantage in that the mechanical strength in the weld portion is lowered.

웰드 라인의 주원인을 살펴보면 다음과 같다. The main causes of the weld line are as follows.

① 구조적 원인 : 제품 내에 홀(Hole) 또는 두께편차에 의해 웰드라인(Weld Line) 생성 되며, 이 경우는 디자인의 변경없이 없애기는 어려우며 눈에 보이지 않게 하는 방법 밖에 없다. 즉 웰드라인의 위치를 변경하 는것이 좋다.     ① Structural cause: Weld line is created by hole or thickness deviation in the product. In this case, it is difficult to eliminate without changing the design and there is only a method to make it invisible. In other words, it is better to change the position of the weld line.

② 수지의 원인 : 수지와 첨가제의 상용성 또는 가스 발생에 의해 웰드라인 생성된다.     ② Cause of resin: Weld line is generated by the compatibility of resin and additive or gas generation.

③ 성형 및 금형상의 원인 : 가혹한 조건에서 사출에 의한 가스 발생 또는 수지의 온도, 압력 등이 너무 낮은 경우, 금형에 가스벤트(Gas vent)가 충분하지 않은 경우에 웰드라인이 발생된다.     ③ Cause of molding and mold: Weld line occurs when there is not enough gas vent in the mold when gas is generated by injection or resin temperature and pressure are too low under severe conditions.

상기와 같이 종래의 센서 고정용 홀더는 사출방식이 사이드 게이트를 이용한방법으로 웰드라인 발생이 심하여 품질을 저하시키는 큰 문제점이 있다. As described above, the conventional holder for fixing the sensor has a large problem in that the weld line is severely generated by the method of using the side gate of the injection method, thereby degrading the quality.

본 발명은 상기와 같은 문제점을 해결하기 위하여 발명한 것으로서 , 센서 고저용 홀더의 웰드라인 발생을 최대로 억제할 수 있도록 하는데 그 목적이 있다.The present invention has been invented to solve the above problems, and an object thereof is to be able to suppress the weld line generation of the holder for the sensor height to the maximum.

본 발명의 부가적인 목적으로는 센서가 조립되는 홀의 형상을 상이하게 하여 생산성을 향상시키는데 그 부가적인 목적이 있다.It is an additional object of the present invention to improve productivity by differentiating the shape of the hole in which the sensor is assembled.

상기의 과제를 해결하기 위한 수단으로 홀더의 사출 성형시 BURR 발생 및 싱크 마크(SINK MARK) 발생 방지용 도피홈을 구성함으로 해소할 수 있다.As a means for solving the above problems can be solved by configuring the escape groove for preventing the occurrence of BURR and SINK MARK during injection molding of the holder.

또한 본 발명은 홀더에 리브를 추가함으로써 웰드 라인의 대책 및 변형발생을 최소로 억제할 수 있다.In addition, the present invention can minimize the countermeasure and deformation of the weld line by adding a rib to the holder.

그리고 본 발명은 홀더의 생산방식을 사이드 게이트에서 터널 게이트로 성형함으로써 웰드라인의 위치를 변경하여 홀더의 외부에서 보이지 않도록 할 수 있다. In addition, the present invention can change the position of the weld line by forming the production method of the holder from the side gate to the tunnel gate so that it is not visible from the outside of the holder.

상기와 같이 된 본 발명은 구조가 간단하여 제작이 용이하고, 홀더의 윌드라인을 최대로 억제할 수가 있어 홀더의 외관을 미려할게 할수 있다.The present invention as described above is simple in structure and easy to manufacture, and can restrain the holder's winding line to the maximum, thereby making the holder's appearance beautiful.

또한 본 발명은 오 조립 방지용 사각홀의 크기를 다르게 하여 생산성을 최대로 향상시킬수 있으며, 도피홈 추가에 따라 BURR 발생 및 싱크 마크를 방지할 수 있는 유용한 발명이다. In addition, the present invention can improve productivity to the maximum by varying the size of the square hole for preventing mis-assembly, it is a useful invention that can prevent the occurrence of BURR and sink marks in accordance with the addition of the escape groove.

홀더(1)의 상부 양측에 4각의 조립홀(2)(2')의 크기를 다르게 하여 오 조립을 방지할 수 있도록 하고,By varying the size of the four square assembling holes (2) (2 ') on both sides of the upper part of the holder (1), it is possible to prevent misassembly,

홀더(1)의 플랜지(3) 하단부에 수직으로 리브(4)를 형성하여 플랜지에 웰드라인이 발생하는 것을 최소로 하며,A rib 4 is formed perpendicularly to the lower end of the flange 3 of the holder 1 to minimize the generation of weld lines in the flange,

리브(4)의 양측에는 경사지게 플로우 리더(FLOW LEADER)(5)를 보강하고, 홀(6)의 내부에 에어벤트(7)를 추가하여 웰드라인 및 변형의 발생을 억제하도록 하여서 된 것으로서, 미설명 부호 10은 센서, 20은 범퍼를 보인 것이다. The ribs 4 are inclined to reinforce the flow leader 5 and to add an air vent 7 to the inside of the hole 6 so as to suppress the occurrence of weld lines and deformations. Reference numeral 10 is a sensor and 20 is a bumper.

상기와 같이 된 본 발명은 터널 게이트를 이용하여 홀더(1)의 중간부에서 게이트가 형성되게 하여 사출 성형함으로써 웰드 라인이 발생하는 위치를 변경하여 홀더의 외부에서 보이지 않도록 할 수가 있다.According to the present invention as described above, the gate is formed in the middle portion of the holder 1 by using the tunnel gate, and the injection molding is performed to change the position where the weld line is generated so that it is not visible from the outside of the holder.

한편 본 발명은 홀더(1)의 중간부에 수직으로 리브(4)가 형성되고, 리브(4)의 양측에는 하향 경사지게 플로우 리더(5)가 형성되며, 홀(6)의 내부에는 에어 벤트(7)가 형성되어 있기 때문에 터널 게이트를 이용하여 사출성형 할 경우 수지의 흐름이 용이하므로 제품의 성형성이 향상되고, 윌드 라인과 변형을 최소로 줄일 수가 있다. Meanwhile, in the present invention, the ribs 4 are vertically formed in the middle part of the holder 1, the flow readers 5 are formed to be inclined downward on both sides of the ribs 4, and the air vents are formed in the holes 6. 7) is formed, so that the injection of resin using tunnel gate facilitates the flow of resin, which improves the moldability of the product and minimizes the number of wire lines and deformations.
