상기 상하윙(20)과 좌우윙(30)은 하우징(50)의 내측면에 힌지 연결되도록 양끝단면에 힌지축(22,32)이 형성되고, 일측 끝단면 후방에는 일부가 절개되어 공간부(23,33)를 형성하고 상기 공간부(23,33)에는 상기 상하윙(20)이 힌지축(22)을 중심으로 연동되도록 연동축(24,34)이 형성된다.The upper and lower wings 20 and the left and right wings 30 are hinged shafts 22 and 32 are formed at both end surfaces so as to be hinged to the inner surface of the housing 50, and a portion of the one end surface is cut behind the space portion ( 23 and 33 are formed, and interlocking shafts 24 and 34 are formed in the spaces 23 and 33 so that the upper and lower wings 20 are interlocked around the hinge shaft 22.

그리고, 타측 끝단면 후방에는 상기 하우징(50)의 내측면에 형성된 가이드홈(54)에서 가이드되어 상기 상하윙(20)과 좌우윙(30)의 회전을 제한하는 가이드 돌기(36)가 형성된다.In addition, a guide protrusion 36 which is guided by the guide groove 54 formed on the inner surface of the housing 50 to limit the rotation of the upper and lower wings 20 and the left and right wings 30 is formed at the rear of the other end surface. .

상기 조절손잡이(40)는 전면과 상면 전측에 그물형상의 파지홈(46)을 형성하고, 후측에는 삽입홈(42)이 형성되어 상기 상하윙(20)이 사이에 끼워지며, 상기 삽입홈(42)의 내측 상하면에는 걸림턱(44) 형성된다.The control knob 40 is formed in the front and upper surface of the gripping groove 46 of the net shape, the insertion groove 42 is formed on the rear side is sandwiched between the upper and lower wings 20, the insertion groove ( A locking jaw 44 is formed on the inner upper and lower surfaces of the 42.

상기 작동부(80)는 상기 조절손잡이(40)에 결합되기 위해 상기 걸림턱(44)에 걸리는 몸체(82)을 형성하며, 전면에는 탄성편(84), 후면에는 그립바(86)가 일체로 사출 성형된다.The operation unit 80 forms a body 82 that is caught on the locking jaw 44 to be coupled to the adjustment handle 40, the elastic piece 84 on the front, the grip bar 86 on the back Is injection molded into.

상기 탄성편(84)은 전면이 일정간격 함몰부(88)를 형성하여 상기 상하윙(20)의 가이드부(28)와의 마찰력을 줄이는 것이 바람직하다.The elastic piece 84 is preferably the front surface is formed with a predetermined interval depression 88 to reduce the frictional force with the guide portion 28 of the upper and lower wings 20.

그리고, 상기 그립바(86)는 후측 양방으로 연장되어 사이에 상기 좌우윙(30)의 일부가 중앙에 삽입된다.In addition, the grip bar 86 extends in both rear sides so that a part of the left and right wings 30 is inserted into the center.

이하, 본 발명에 따른 차량용 에어벤트 구조의 작용 및 효과를 살펴보도록 한다.Hereinafter, the operation and effects of the vehicle air vent structure according to the present invention will be described.

도 3에서 도시한 바와 같이, 먼저 상기 상하윙(20)과 좌우윙(30)의 일측 공간부(23,33)에 형성된 연동축(24,34))에 연동편(29)이 결합하여 다수개의 상하윙(20)과 좌우윙(30)이 연동되게 결합된다.As shown in FIG. 3, first, the interlocking piece 29 is coupled to the interlocking shafts 24 and 34 formed on one side spaces 23 and 33 of the upper and lower wings 20 and the left and right wings 30. The upper and lower wings 20 and left and right wings 30 are coupled to interlock.

상기 다수개의 상하윙(20) 중에 중앙에 위치한 상하윙(20)의 중앙부에 조절손잡이(40)의 삽입홈(42)가 끼워진다.The insertion groove 42 of the adjustment knob 40 is fitted to the central portion of the upper and lower wings 20 located in the center of the plurality of upper and lower wings 20.

그리고, 상기 삽입홈(42)에 끼워진 상하윙(20)의 후면에는 작동부(80)가 결합된다.Then, the operation unit 80 is coupled to the rear surface of the upper and lower wings 20 fitted in the insertion groove 42.

상기 삽입홈(42)의 내측 상하면에는 걸림턱(44)이 형성되어 상기 작동부(80)의 몸체(82)가 걸리게 되어 결합된다.A locking jaw 44 is formed on the inner upper and lower surfaces of the insertion groove 42 to engage and engage the body 82 of the operation unit 80.

상기 작동부(80)의 전면에 일체로 사출 성형된 탄성편(84)이 탄성력에 의해 조립 공차로 발생되는 흔들림을 억제되어 단단히 고정된다.The elastic piece 84 integrally injection-molded on the front surface of the operating part 80 is firmly fixed by suppressing the shaking caused by the assembly tolerance by the elastic force.

또한, 일체로 플라스틱 사출됨으로 부품의 질량을 경량화 할 수 있으며, 상기 탄성편의 전면에 함몰부(88)를 형성하여 마찰력을 줄임으로써, 접합되는 부위를 긁는 현상을 방지한다.In addition, it is possible to reduce the mass of the parts by integrally plastic injection, and to reduce the frictional force by forming a depression 88 on the front surface of the elastic piece, to prevent the phenomenon of scratching the joined portion.

상기 상하윙(20)과 좌우윙(30)의 양끝단면에 형성된 힌지축(22,32)은 상기 하우징(50)의 내측 내부에 형성된 힌지홈(52)에 결합된다.Hinge shafts 22 and 32 formed at both end surfaces of the upper and lower wings 20 and the left and right wings 30 are coupled to the hinge grooves 52 formed inside the housing 50.

이때, 상기 힌지축(22,32)의 후방에 형성된 가이드 돌기(36)는 상기 하우징(50)의 가이드 홈(54)에 결합된다.In this case, the guide protrusion 36 formed at the rear of the hinge shafts 22 and 32 is coupled to the guide groove 54 of the housing 50.

그리고, 상기 작동부(80)의 후측에 형성된 그립바(86)에 상기 좌우윙(30)의 일부가 삽입된다.In addition, a part of the left and right wings 30 is inserted into the grip bar 86 formed at the rear side of the operation part 80.

상기 조절손잡이(40)의 파지홈(46)을 잡고, 상기 조절손잡이(40)를 상하로 움직이면, 상기 상하윙(20)이 힌지축(22)을 중심으로 회전하여 풍향을 상하로 조절하고, 이때, 상기 가이드 돌기(26)가 상기 가이드 홈(54)에서 가이드 되어 회전을 제한한다.Holding the gripping groove 46 of the control knob 40, and moving the control knob 40 up and down, the upper and lower wing 20 is rotated about the hinge axis 22 to adjust the wind direction up and down, At this time, the guide protrusion 26 is guided in the guide groove 54 to limit the rotation.

그리고, 상기 좌우윙(30)의 작동은 상기 조절손잡이(40)를 좌우로 이동이면, 상기 좌우윙(30)이 힌지축(32)을 중심으로 회전되어 풍향을 좌우로 조절한다.And, the operation of the left and right wings 30, the left and right wing 30 is rotated about the hinge axis 32 when the control knob 40 is moved left and right to adjust the wind direction to the left and right.

이때, 상기 좌우윙(30)은 상기 상하윙(20)의 후측면에 형성된 가이드부(28)에 의해 제한된다.At this time, the left and right wings 30 are limited by the guide portion 28 formed on the rear side of the upper and lower wings 20.

상기와 같은 구조에 의하면, 다수개의 상하윙과 좌우윙을 조작하여 풍향을 조정하는데 있어서, 상기 탄성편과 작동부를 일체로 플라스틱 사출함으로써, 부품의 수를 줄이고, 조립공정을 간단히 하며, 비용절감의 효과가 있다.According to the structure as described above, in adjusting the wind direction by operating a plurality of upper and lower wings and left and right wings, by injecting the elastic piece and the operating unit integrally plastic, the number of parts is reduced, the assembly process is simplified, and the cost is reduced. It works.

그리고, 상기 탄성편의 전면에 함몰부를 형성함으로써, 상기 가이드부와 탄성편의 마찰력을 줄이므로 상기 가이드부에서 슬라이딩될 때, 플라스틱을 긁는 현상을 억제한다.And, by forming a depression on the front surface of the elastic piece, the friction force between the guide portion and the elastic piece is reduced, thereby suppressing the phenomenon of scratching the plastic when sliding in the guide portion.

상기한 바와 같이 본 발명에 따른 차량용 송풍기의 풍향 조절부 구조에 의하면 다수개의 상하윙과 좌우윙을 조작하여 풍향을 조절하는데 있어서, 일단은 상기 상하윙의 후면을 가압하고, 접촉부를 긁는 형상을 방지하는 탄성편이 작동부에 일 체로 사출 성형되어, 조립 공차 및 형상 변경 공차를 줄여 작동력에 의한 산포를 향상시키는 장점이 있다.As described above, according to the structure of the wind direction control unit of the vehicle blower according to the present invention in controlling the wind direction by operating a plurality of upper and lower wings and left and right wings, one end presses the rear surface of the upper and lower wings, and prevents the shape of scratching the contact portion. The elastic piece is injection molded integrally with the operating unit, there is an advantage to improve the dispersion due to the operating force by reducing the assembly tolerance and shape change tolerance.

또한, 조립 공정을 삭제하고 부품수를 감소시켜 원가 절감하는 효과가 있다.In addition, the cost is reduced by eliminating the assembly process and reducing the number of parts.
