Abstract

PURPOSE: A device for absorbing the impact of a pivot shaft for a wiper arm is provided to absorb the impact by decreasing the height of the pivot shaft and to protect a human body when some of the human body hits on the pivot shaft. CONSTITUTION: After inserting a stop ring(12) at the upper end of a pivot shaft(1), an impact absorbing member(4) is prepared between the stop ring and an upper end face of a pivot housing(11). The impact absorbing member is formed in bellows shape so that when the pivot shaft is pressed by impact, the impact absorbing member is plastically deformed. A planar washer(14) is additionally prepared on upper and lower parts of the impact absorbing member. When the external impact is reacted to the pivot shaft, the pivot shaft is pressed downwardly. The stop ring fixed at the upper end of the pivot shaft presses the upper end of the impact absorbing member. Accordingly, as the impact absorbing member is plastically deformed according to a crease, the impact is absorbed in the process of the plastic deformation.

자동차의 와이퍼 아암용 피봇축의 충격흡수장치{Impulse absorption apparatus of pivot axis for wiper arm of car}Impact absorption apparatus of pivot axis for wiper arm of car}

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 입설된 피봇 하우징, 상기 피봇 하우징의 중앙에 입설된 채, 링크로부터 회전 동력을 전달 받은 피봇축, 상기 피봇축의 상단에 축설된 와이퍼 아암으로 이루어진 차량용 와이퍼 구동장치에 있어서, 상기한 피봇축의 상단에 스톱링을 끼운 후, 이 스톱링과 상기 피봇 하우징의 상단면 사이에 충격흡수부재를 내장하여, 피봇축의 상단에서 길이 방향으로 작용하는 충격에 대해 완충작용을 할 수 있도록 하는데 있다.Characteristic means for this is a plate that is fixed as part of the vehicle body, a pivot housing installed as a bracket on the plate, a pivot shaft which is installed in the center of the pivot housing, receives the rotational power from the link, at the top of the pivot shaft In the vehicle wiper drive device comprising a built-in wiper arm, the stop ring is fitted to the upper end of the pivot shaft, thereafter built a shock absorbing member between the stop ring and the upper surface of the pivot housing, the longitudinal direction from the upper end of the pivot shaft It is to be able to buffer against the impact acting.

이하 본 발명의 실시예에 따른 구성 및 작용을 첨부 도면에 따라 상세히 설명한다.Hereinafter, the configuration and operation according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 피봇축(1)에 와이퍼 아암(2)이 축설된 상태를 보인 예시도이고, 도 2는 본 발명의 구성에 따른 와이퍼 아암용 피봇축(1)의 구성을 보인 단면도이다.1 is an exemplary view showing a state in which the wiper arm 2 is arranged on the pivot shaft 1, and FIG. 2 is a cross-sectional view showing the configuration of the pivot shaft 1 for the wiper arm according to the configuration of the present invention.

도면에서 보듯이 차량용 와이퍼 구동장치는 차체(3)의 일부로 고정되어 있는 플레이트(31)와, 상기 플레이트(31)상에서 브라켓트(32)로써 입설된 피봇 하우징(11), 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 11 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.

이때, 상기한 피봇축(1)의 상단에 스톱링(12)을 끼운 후, 이 스톱링(12)과 상기 피봇 하우징(11)의 상단면 사이에 충격흡수부재(4)를 개입시켜 구성하는 것이 특징이다.At this time, the stop ring 12 is inserted into the upper end of the pivot shaft 1, and the shock absorbing member 4 is interposed between the stop ring 12 and the upper end surface of the pivot housing 11. Is characteristic.

충격흡수부재(4)는 주름관 모양으로 이루어져 충격 발생으로 인해 피봇축(1)이 눌리면 소성변형 되도록 한 것이며, 충격흡수부재(4)의 위와 아래에는 평판형 와셔(14)를 추가로 개시키는 것이 바람직하다.The shock absorbing member 4 is formed in a corrugated pipe shape so that the plastic shaft is deformed when the pivot shaft 1 is pressed due to the impact, and the flat washer 14 is additionally opened above and below the shock absorbing member 4. desirable.

도면중 미설명 부호 15는 부시이고, 16은 O링이다.In the figure, reference numeral 15 is a bush, and 16 is an O-ring.

이와 같이 구성된 본 발명은 외부의 충격이 피봇축(1)상에 작용하면 피봇축(1)이 아래로 눌리게 되고, 피봇축(1)의 상단에 고정된 스톱링(12)이 충격흡수부재(4)의 상단을 누르게 된다.According to the present invention configured as described above, when an external shock acts on 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 has an impact absorbing member. Press the top of (4).

따라서 피봇 하우징(11)과의 사이에 개입된 충격흡수부재(4)는 주름을 따라 소성변형이 발생하므로 소성변형되는 과정에서 충격을 흡수하게 되는 것이다.Therefore, the impact absorbing member 4 interposed between the pivot housing 11 is to absorb the impact in the process of plastic deformation because plastic deformation occurs along the wrinkles.

위에서 상세히 설명한 바와 같은 본 발명은 전면 유리의 아랫부분에서 돌출되어 있는 와이퍼 아암용 피봇축(1)에 충격흡수부재(4)를 이용하여 충격을 흡수하면서 길이가 줄어들 수 있도록 하였기 때문에 인체가 부딪혔을 경우 완충효과를 얻을 수 있게 되는 것이다.The present invention as described above in the case of hitting the human body to reduce the length while absorbing the impact using the shock absorbing member (4) to the wiper arm pivot shaft (1) protruding from the lower portion of the windshield The buffer effect will be obtained.
