Description

차량용 히팅덕트의 장착구조{Mounting structure of heating-duct for vehicle}Mounting structure of heating-duct for vehicle

본 발명은 차량용 히팅덕트의 장착구조에 관한 것으로 더욱 상세하게는 전방크로스멤버에 형성된 덕트홀에 커넥팅덕트를 추가적으로 장착함으로서 상기 전방크로스멤버의 강성을 향상시키고 제1덕트와 제2덕트를 더 용이하게 조립할 수 있는 차량용 히팅덕트의 장착구조에 관한 것이다.
The present invention relates to a mounting structure of a vehicle heating duct, and more particularly, by additionally installing a connecting duct in a duct hole formed in the front cross member, thereby improving the rigidity of the front cross member and making the first and second ducts easier. It relates to a mounting structure of a vehicle heating duct that can be assembled.

차량의 공조장치는 실내 온도를 적정 상태로 유지하기 위하여 차량에 탑재되는 장치로서 상온 보다 덥혀지거나 냉각된 공기를 블로워모터를 통해 승객석으로 송풍시키도록 구성된다. The air conditioner of the vehicle is a device mounted on the vehicle to maintain the room temperature in a proper state, and is configured to blow air heated or cooled above the room temperature to the passenger seat through the blower motor.

일반적인 승용차량에 있어 상기 공조장치를 통해 생성된 냉풍 또는 온풍은 통상적으로 운전석 전면에서 토출되도록 구성된다. In a general passenger vehicle, cold or warm air generated through the air conditioning apparatus is typically configured to be discharged from the front of the driver's seat.

그러나, 상대적으로 차체길이가 긴 중대형 승용차나 RV 또는 SUV 승용차량은 운전석 후방쪽의 냉/난방 효과를 높이기 위해 리어 히팅덕트(rear heating duct)가 추가되어 냉풍 또는 온풍이 토출되도록 구성된다.However, medium and large passenger cars or RV or SUV passenger vehicles having a relatively long body length are configured such that a rear heating duct is added to increase cooling / heating effect at the rear of the driver's seat so that cold or warm air is discharged.

즉, 상기 히팅덕트는 차체의 전방측에서 후방 시트(seat) 쪽까지 연장되게 장착된 구조로서 공조장치에서 생성된 냉풍 또는 온풍이 차량 실내 후방측으로 토출되도록 통로를 제공한다.That is, the heating duct extends from the front side of the vehicle body to the rear seat side and provides a passage for discharging cold or warm air generated by the air conditioning apparatus to the rear side of the vehicle interior.

도 1a 는 종래의 방식에 따라 히팅덕트가 부설된 모습과 단면도가 도시되어 있다. 도면을 참조하면, 차체에는 시트를 장착하기 위하여 차체의 길이방향을 따라 전방크로스멤버(20)와 후방크로스멤버(30)가 나란히 배치된다. Figure 1a is a cross-sectional view and a heating duct is laid in a conventional manner. Referring to the drawings, the front cross member 20 and the rear cross member 30 are arranged side by side along the longitudinal direction of the vehicle body to mount the seat.

그리고, 상기 히팅덕트는 전방크로스멤버(20)를 사이에 두고 제1덕트(40)와 제2덕트(50)가 연결되어 구성된다. 따라서, 전방크로스멤버(20)에는 제1덕트(40)나 제2덕트(30)가 끼워져 관통될 수 있도록 덕트홀이 형성된 구조를 갖는다. In addition, the heating duct is configured by connecting the first duct 40 and the second duct 50 with the front cross member 20 therebetween. Therefore, the front cross member 20 has a structure in which a duct hole is formed so that the first duct 40 or the second duct 30 can be inserted therethrough.

종래의 구조에서는 제2덕트(50)의 앞쪽(전방) 끝단이 덕트홀의 전방측에서 소정 길이만큼 돌출되도록 장착된 후, 상기 돌출부분에 제1덕트(40)의 뒷쪽(후방) 끝단이 끼워지면 겹쳐진부분에 미리 타공된 볼트홀에 볼팅체결하는 방식으로 조립이 이뤄졌었다.
In the conventional structure, the front (front) end of the second duct 50 is mounted to protrude by a predetermined length from the front side of the duct hole, and then the rear (rear) end of the first duct 40 is fitted to the protruding portion. The assembly was done by bolting into bolt holes pre-drilled in the overlapped areas.

하지만, (제1덕트와 제2덕트의) 볼트홀들이 맞춰지는 위치는 덕트홀에서 제2덕트가 돌출된 정도에 따라 달라지기 때문에 조립 시 불편함을 유발하였다. 또한, 제2덕트를 전방크로스멤버에 삽입하는 과정에서 상기 제2덕트가 파손될 우려가 있었다.However, the position where the bolt holes (of the first duct and the second duct) are fitted depends on the extent of the second duct protruding from the duct hole, thereby causing inconvenience in assembly. In addition, the second duct may be damaged while the second duct is inserted into the front cross member.

아울러, 도 1b 에 표시된 바와 같이 덕트홀이 형성된 주변은 강성이 취약하여 차체에 충격이 가해지면 덕트홀에 변형이 발생할 우려가 있었다.In addition, as shown in FIG. 1B, the periphery in which the duct hole is formed is weak and there is a fear that deformation may occur in the duct hole when an impact is applied to the vehicle body.

그리고, 제2덕트의 조립성을 향상시키기 위하여 제2덕트의 진입시 덕트홀과 사이의 조립공차는 3mm 이상 크기로 설정해야 하나 이러한 공차는 전방크로스멤버의 강성을 약화시킬 수 있었으며, 승차감 개선을 위해선 시트의 장착위치는 가급적 낮게 설정되어하므로 강성향상을 위해서 전방크로스멤버 및 후방크로스멤버의 높이를 증가시키는 것을 한계가 있었다.In addition, in order to improve the assemblability of the second duct, the assembly tolerance between the duct hole and the entrance should be set to 3 mm or more in size, but this tolerance could weaken the rigidity of the front cross member, Since the mounting position of the seat is set as low as possible, there was a limit to increasing the height of the front cross member and the rear cross member in order to improve rigidity.

따라서, 본 발명은 상기와 같은 문제점을 해소하기 위하여 발명된 것으로서 덕트홀 타공에 의해 취약진 전방크로스멤버의 강성을 보강할 수 있으며 제1덕트와 제2덕트를 더욱 용이하게 연결할 수 있는 차량용 히팅덕트의 장착구조를 제공하는 것에 주목적이 있다.
Therefore, the present invention has been invented to solve the above problems and can reinforce the rigidity of the front cross member vulnerable by the duct hole perforation and the vehicle heating duct that can more easily connect the first duct and the second duct The main purpose is to provide a mounting structure.

상기와 같은 목적을 달성하기 위한 본 발명은, 시트가 장착되도록 차체길이 방향으로 따라 이격되어 전방크로스멤버와 후방크로스멤버가 나란히 배치되되, 전방크로스멤버의 앞쪽에 위치하는 제1덕트와 뒷쪽 끝단이 후방크로스멤버에 연결되는 제2덕트가 상기 전방크로스멤버에 형성된 덕트홀을 통하여 연결되는 차량용 히팅덕트의 장착구조에 있어서, 상기 덕트홀에 끼워져 전방 끝단은 제1덕트의 뒷쪽 끝단에 연결되고 후방 끝단은 제2덕트이 앞쪽 끝단에 연결되어 상기 제1덕트와 제2덕트를 개통하는 커넥팅덕트;를 포함하는 것을 특징으로 한다.The present invention for achieving the above object, the front cross member and the rear cross member are arranged side by side spaced apart along the vehicle body length direction so that the seat is mounted, the first duct and the rear end is located in front of the front cross member In the mounting structure of the vehicle heating duct is a second duct connected to the rear cross member is connected through the duct hole formed in the front cross member, the front end is fitted into the duct hole is connected to the rear end of the first duct and the rear end It is characterized in that it comprises a; connecting the second duct is connected to the front end opening the first duct and the second duct.

상기 커넥팅덕트는 전방 끝단과 후방 끝단 각각이 전방크로스멤버에서 돌출되도록 형성된다.The connecting duct is formed such that each of the front end and the rear end protrudes from the front cross member.

그리고, 상기 커넥팅덕트 끝단에는 직경이 증가되도록 확장부가 절곡형성되며, 상기 확장부는 커넥팅덕트의 후방 끝단에 형성되고, 상기 제2덕트의 끝단은 확장부에 체결되도록 오므려진 모양으로 형성된다.
An extension portion is bent at an end portion of the connecting duct so as to increase a diameter. The extension portion is formed at a rear end portion of the connecting duct, and an end portion of the second duct is formed to be pinched to be fastened to the extension portion.

상기와 같은 구성의 본 발명은, 덕트홀에 커넥팅덕트가 끼워지므로 상기 덕트홀의 타공에 따라 취약해진 전방크로스멤버의 강성을 보강할 수 있는 효과가 있다.According to the present invention, the connecting duct is inserted into the duct hole, so that the rigidity of the front cross member weakened by the perforation of the duct hole can be reinforced.

상기 전방크로스멤버에 커넥팅덕트가 고정된 상태로 제1덕트와 제2덕트가 연결되어 (볼트홀의 위치가 고정되므로) 조립성을 향상시킬 수 있으며, (제2덕트의 진입을 위한 공차를 없앨 수 있으므로) 추가적인 강성저하를 방지할 수 있는 효과가 있다. The first duct and the second duct are connected to the front cross member while the duct is fixed (because the position of the bolt hole is fixed), thereby improving the assemblability and eliminating the tolerance for the entry of the second duct. Therefore, there is an effect that can prevent additional degradation of rigidity.

아울러, 결합되는 위치가 더 견고히 고정되므로 용접과 같은 다른 방식을 통하여 연결될 수 있다.
In addition, the combined position is more firmly fixed and can be connected through other methods such as welding.
