본 발명은 자동차의 와이퍼 아암용 피봇축의 충격흡수장치에 대한 것으로서, 더 상세하게는 인체가 충격되었을 때, 인체의 손상을 최대한 예방하기 위해 그 길이가 축소될 수 있도록 하는데 특징이 있는 것이다.The present invention relates to a shock absorbing device of a pivot shaft for a wiper arm of an automobile, and more particularly, when the human body is impacted, its length can be shortened to prevent damage to the human body as much as possible.

일반적으로 자동차용 와이퍼는 전방 유리창 또는 후방 유리창을 닦기 위한 기구로서, 전방 유리창의 경우 도 1에서 보는 바와 같이 유리창이 설치된 직하방에 모터(도시하지 않았음)와, 동력전달 링크(13) 등에 의해 회전 및 반전하는 피봇축(1)이 마련되어 있고, 이 피봇축(1)에 와이퍼 아암(2)의 헤드부(21)가 고정되어 함께 회전하도록 되어 있다.In general, an automobile wiper is a mechanism for wiping the front windshield or the rear windshield, and in the case of the front windshield, as shown in FIG. 1, a motor (not shown) and a power transmission link 13 or the like directly below the windshield are installed. The pivot shaft 1 which rotates and inverts is provided, and the head part 21 of the wiper arm 2 is fixed to this pivot shaft 1, and it rotates together.

한편, 근래에는 자동차가 인체와 충돌하였을 경우를 대비하여 상기와 같이 돌출된 피봇축(1)에도 충격흡수장치를 설치하기에 이르렀다.On the other hand, in recent years, in the case where the car collides with the human body, it came to install a shock absorbing device to the protruding pivot shaft (1) as described above.

즉, 차량의 정면쪽으로 인체에 부딪히게 되면 인체의 상반신이 차량의 후드판넬(33)위로 떨어지게 되고, 특히 머리부분이 상기의 피봇축(1) 위치에서 접촉하기 쉽상이기 때문에 충격흡수장치를 구비할 필요가 있는 것이다.That is, when hitting the human body toward the front of the vehicle, the upper body of the human body falls on the hood panel 33 of the vehicle, in particular, because the head portion is easy to contact at the position of the pivot shaft (1) to provide a shock absorbing device There is a need.

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 안출한 것으로서, 발명의 주된 목적은 신체의 일부가 와이퍼 아암용 피봇축에 충격되었을 때, 피봇축의 높이가 줄어 들어 충격을 흡수할 수 있도록 하는데 있으며, 더 나가서 인체를 보호할 수 있도록 하고자 하는 것이다.Therefore, the present invention has been made in view of the above-mentioned conventional problems to solve the problem, the main object of the invention when the body part is impacted on the pivot axis for the wiper arm, the height of the pivot axis is reduced to absorb the shock It is to make it possible to go out and to protect the human body.

이를 위한 특징적인 수단은 차체의 일부로 고정되어 있는 플레이트와, 상기 플레이트 상에서 브라켓트로써 입설 고정된 피봇 하우징, 상기 피봇 하우징의 중앙에 끼워진 채, 링크로부터 회전 동력을 전달 받은 피봇축, 상기 피봇축의 상단에 축설된 와이퍼 아암으로 이루어진 차량용 와이퍼 구동장치에 있어서, 상기한 피봇 하우징과 피봇축의 사이에 충격흡수관재를 개입시키되, 이 충격흡수관재는 상측의 환테부와, 그 아래의 지지환턱들을 형성한 것으로 하고, 상기한 피봇 하우징의 상단 내경에는 확장내경부를 형성한 후, 그 중단에 중앙을 향해 돌설된 다수의 돌출편들을 형성하여 상기 지지환턱이 얹힐 수 있도록 하고, 상기한 피봇축의 상단에는 스톱링을 끼운 후, 이 스톱링과 상기 충격흡수관재의 사이에 원판와셔와, 완충와셔를 개입하여, 피봇축의 상단에서 길이 방향으로 작용하는 충격에 대해 상기한 돌출편들이 꺾이면서 완충작용을 할 수 있도록 하는데 있다.Characteristic means for this is a plate which is fixed as part of the vehicle body, a pivot housing fixed as a bracket on the plate, a pivot shaft which is inserted in the center of the pivot housing, receives the rotational power from the link, on top of the pivot shaft In a vehicle wiper drive device comprising an installed wiper arm, an impact absorbing tube member is interposed between the pivot housing and the pivot shaft, and the shock absorbing tube member is formed by forming an upper annulus portion and a supporting lower portion thereof. After the expansion inner diameter is formed on the upper inner diameter of the pivot housing, a plurality of protrusions protruding toward the center of the pivot housing are formed so that the support ring can be placed thereon, and the stop ring is provided on the upper end of the pivot shaft. After insertion, the pivot ring is interposed between the stop ring and the shock absorbing tube member through a disc washer and a buffer washer. It is to allow the above-mentioned protruding pieces to be bent and cushioned against the impact acting in the longitudinal direction at the top of the shaft.

도면에서 보듯이 차량용 와이퍼 구동장치는 차체(3)의 일부로 고정되어 있는 플레이트(31)와, 상기 플레이트(31)상에서 브라켓트(32)로써 입설된 피봇 하우징(5), 상기 피봇 하우징의 중앙에 입설된 채, 링크(13)로부터 회전 동력을 전달 받은 피봇축(1), 상기 피봇축(1)의 상단에 축설된 와이퍼 아암(2)으로 이루어져 있다.As shown in the drawing, the vehicle wiper drive includes a plate 31 fixed as a part of the vehicle body 3, a pivot housing 5 installed as a bracket 32 on the plate 31, and a center of the pivot housing. It consists of a pivot shaft 1 which receives rotational power from the link 13 and a wiper arm 2 which is arranged on the upper end of the pivot shaft 1.

본 발명에서는 상기한 피봇 하우징(5)과 피봇축(1)의 사이에 충격흡수관재(4)를 개입시키되, 이 충격흡수관재(4)는 상측의 환테부(41)와, 그 아래의 지지환턱(42)들을 형성한 것으로 하고, 상기한 피봇 하우징(5)의 상단 내경에는 확장내경부(52)를 형성한 후, 그 중단에 중앙을 향해 돌설된 다수의 돌출편(51)들을 형성하여 상기 지지환턱(42)이 얹힐 수 있도록 하고, 상기한 피봇축(1)의 상단에는 스톱링(12)을 끼운 후, 이 스톱링(12)과 상기 충격흡수관재(4)의 환테부(41) 사이에 원판와셔(11)와, 완충와셔(6)를 개입하여, 피봇축(1)의 상단에서 길이 방향으로 작용하는 충격에 대해 상기한 돌출편(51)들이 꺾이면서 완충작용을 할 수 있도록 하는 것이 중요하다.In the present invention, while the impact absorbing tube member 4 is interposed between the pivot housing 5 and the pivot shaft 1, the shock absorbing tube member 4 has an upper annular portion 41 and a support below it. After forming the round jaw (42), the inner diameter of the upper end of the pivot housing (5) is formed an inner diameter of the expansion portion 52, and then formed a plurality of protruding pieces (51) protruding toward the center at the interruption The support ring jaw 42 is to be mounted, and the stop ring 12 is inserted into the upper end of the pivot shaft 1, the ring ring portion 41 of the stop ring 12 and the shock absorbing pipe member (4). Between the disc washer 11 and the buffer washer 6, the above-described protrusions 51 can be buffered against the impact acting in the longitudinal direction from the upper end of the pivot shaft (1). It is important to ensure that

이때, 상기한 원판와셔(11)는 금속재로 하는 것이 바람직하고, 완충와셔(6)는 약간의 자체 탄성력을 가지는 비금속재로써 형성하는 것이 좋다.At this time, the disc washer 11 is preferably made of a metal material, the buffer washer 6 is preferably formed of a non-metal material having a slight self-elasticity.

이와 같이 구성된 본 발명은 외부의 충격이 피봇축(1)의 길이 방향으로 작용하면 피봇축(1)이 아래로 눌리게 되고, 피봇축(1)의 상단에 고정된 스톱링(12)이 원판와셔(11) 및 완충와셔(6)와 함께 충격흡수관재(4)의 상단 환테부(41)를 누르게 된다.In the present invention configured as described above, when the external impact acts in the longitudinal direction of the pivot shaft 1, the pivot shaft 1 is pressed downward, and the stop ring 12 fixed to the upper end of the pivot shaft 1 is a disc. Along with the washer 11 and the buffer washer 6, the upper annular portion 41 of the shock absorbing tube member 4 is pressed.

환테부(41) 즉, 충격흡수관재(4)가 하강하면, 그 아래에 형성된 지지환턱(42)이 피봇 하우징(5)의 확장내경부(52)에서 중앙을 향해 돌설된 돌출편(51)에 얹혀 있다가 이들을 파손시키면서 확장내경부(52)를 따라 내려가는데 이때 대부분의 충격을 흡수하게 되는 것이며, 마지막으로 완충와셔(6)가 눌리면서 2차적으로 나머지 충격을 흡수하게 되는 것이다.When the annulus part 41, that is, the impact absorbing pipe member 4 descends, the support ring jaw 42 formed below the protrusion piece 51 protrudes toward the center from the extended inner diameter portion 52 of the pivot housing 5. It is placed on the down and expands along the inner diameter portion 52 while damaging them, which is to absorb most of the shock, and finally the buffer washer (6) is to absorb the rest of the shock secondary.

위에서 상세히 설명한 바와 같은 본 발명은 피봇 하우징(5)과 피봇축(1)의 사이에 충격흡수관재(4)를 내장하되 충격흡수관재(4)의 지지환턱(42)이 피봇 하우징(5) 내부의 돌출편(51)들을 파손시키면서 하강하고, 완충와셔(6)가 눌리도록 구성하였기 때문에 소성변형 및 자체 찬성에 의한 충격흡수작용이 이루어질 수 있게 되는 것이며, 따라서 본 발며에 따른 피봇축(1)은 충격을 받으면 그 길이가 줄어 들어 완충효과를 얻을 수 있기 때문에 최대한 인체를 보호할 수 있게 되는 것이다.According to the present invention as described in detail above, the shock absorbing tube member 4 is embedded between the pivot housing 5 and the pivot shaft 1, but the support ring 42 of the shock absorbing tube member 4 is inside the pivot housing 5. The protrusion pieces 51 are lowered while being damaged, and the buffer washer 6 is configured to be pressed, so that the shock absorbing action can be made by plastic deformation and self-approval, and thus the pivot shaft 1 according to the present footing. When the impact is shortened the length of the shock absorbing effect can be obtained to protect the human body as much as possible.
