Description

차량용 와이퍼 암 체결구조{Screw structure of wiper arm for automobile}Screw structure of wiper arm for automobile}

본 발명은 차량용 와이퍼 암 체결구조에 관한 것으로서, 더욱 상세하게는 와이퍼 암 체결용 캡 너트를 이중구조로 제작하여 체결시 과도한 체결 토크가 가해지는 경우에도 와이퍼 암의 페인트가 벗겨지는 등의 품질문제를 해결할 수 있도록 한차량용 와이퍼 암 체결구조에 관한 것이다.The present invention relates to a wiper arm fastening structure for a vehicle, and more particularly, to produce a wiper arm fastening cap nut in a double structure to solve quality problems such as peeling off the paint of the wiper arm even when an excessive fastening torque is applied during fastening. The present invention relates to a wiper arm fastening structure for a vehicle.

일반적으로 차량용 와이퍼 암(10)은, 도 1에 도시한 바와 같이, 와이퍼 블레이드(11)를 움직여주는 지지대의 역할을 하는 것으로서, 캡 너트(12)에 의해 와이퍼 시스템(13)에 체결되는 구조로 설치된다.Generally, as shown in FIG. 1, the vehicle wiper arm 10 serves as a support for moving the wiper blade 11, and is coupled to the wiper system 13 by the cap nut 12. Is installed.

즉, 도 2에 도시한 바와 같이, 와이퍼 시스템(13)의 피봇(14)에 와이퍼 암(10)의 후단이 삽입되고, 그 위에 캡 너트(12)가 체결되는 구조로 설치된다.That is, as shown in FIG. 2, the rear end of the wiper arm 10 is inserted into the pivot 14 of the wiper system 13, and the cap nut 12 is fastened thereon.

그러나, 작업자가 일반공구나 전동공구를 가지고 캡 너트(12)를 체결할 때, 보통 견고한 체결력을 유지하기 위해 일정 이상의 토크를 가하여 캡 너트(12)를 조이는 경우가 대부분인데, 이때 캡 너트(12)가 돌아가면서 와이퍼 암(10)의 접촉면을 긁어 페인트가 벗겨지는 문제가 있으며, 이로 인해 페인트가 벗겨진 부위에 녹이 발생되는 등 품질문제를 야기하는 문제점이 있었다.However, when the operator tightens the cap nut 12 with a general tool or a power tool, in most cases, the cap nut 12 is tightened by applying a predetermined torque or more to maintain a firm tightening force. There is a problem that the paint is peeled off by scraping the contact surface of the wiper arm 10 while rotating, and this causes problems such as quality problems such as rust generated in the peeled off part of the paint.

따라서, 본 발명은 이와 같은 점을 감안하여 안출한 것으로서, 와이퍼 암의 체결시 일정한 토크 이상이 되면 자체적으로 헛돌 수 있는 이중구조의 캡 너트를 채용함으로써, 체결시 과도한 체결 토크가 가해지는 경우에도 와이퍼 암의 페인트가 벗겨지는 등의 품질문제를 해결할 수 있도록 한 차량용 와이퍼 암 체결구조를 제공하는데 그 목적이 있는 것이다.Therefore, the present invention has been devised in view of the above, by adopting a cap nut of a dual structure that can be turned itself when a certain torque or more at the time of tightening the wiper arm is adopted, even if excessive tightening torque is applied during tightening It is an object of the present invention to provide a vehicle wiper arm fastening structure that can solve quality problems such as peeling off of paint on an arm.

이하, 첨부한 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 캡 너트(12)를 이용하여 와이퍼 시스템(13)에 와이퍼 암(10)을 체결하는 구조에 있어서, 상기 와이퍼 암(10)의 표면에 접촉되면서 고정되는 압착링(15)과 와이퍼 시스템(13)의 피봇(14)에 체결되는 너트(16)의 상호 회전가능한 조합형으로 이루어진 캡 너트(12)를 포함하여 구성되는 것을 특징으로 한다.According to the present invention, in the structure in which the wiper arm 10 is fastened to the wiper system 13 using the cap nut 12, the pressing ring 15 and the wiper system fixed while contacting the surface of the wiper arm 10 are provided. And a cap nut 12 made of a mutually rotatable combination of the nuts 16 fastened to the pivot 14 of (13).

또한, 상기 압착링(15)과 너트(16)는 상하방향의 쐐기형 걸림구조를 포함하면서 자체 축선을 중심으로 하여 서로 자유롭게 회전가능한 구조로 결합되는 것을 특징으로 한다.In addition, the pressing ring 15 and the nut 16 is characterized in that coupled to the structure rotatable freely with each other about its own axis including a wedge-shaped locking structure in the vertical direction.

이를 좀더 상세히 설명하면 다음과 같다.This will be described in more detail as follows.

도 3에 도시한 바와 같이, 와이퍼 시스템(13)의 피봇(14)에 와이퍼 암(10)의 후단부가 세레이션 조합을 통해 관통 결합되고, 와이퍼 암(10)의 윗쪽으로 일부 돌출되는 피봇(14)의 상단 체결부위에 캡 너트(12)가 체결되는 구조에 의해 와이퍼 암(10)이 고정 설치된다.As shown in FIG. 3, the rear end portion of the wiper arm 10 is coupled to the pivot 14 of the wiper system 13 through a serration combination, and the pivot 14 partially protrudes upward of the wiper arm 10. The wiper arm 10 is fixedly installed due to the structure in which the cap nut 12 is fastened to the upper fastening portion of the c).

여기서, 상기 캡 너트(12)는 종전의 일체형 구조가 아니라 너트(16)와 압착링(15)의 조합형 구조 이루어져 있다.Here, the cap nut 12 is a combination structure of the nut 16 and the pressing ring 15, rather than the conventional one-piece structure.

상기 너트(16)는 와이퍼 시스템(13)의 피봇(14)에 실질적으로 체결되면서 체결력을 발휘하는 부분이고, 상기 압착링(15)은 너트(16)의 체결력에 의해 와이퍼 암(10)의 표면과 직접 접촉하는 부분이다.The nut 16 is a part which exerts a fastening force while being substantially fastened to the pivot 14 of the wiper system 13, and the pressing ring 15 is a surface of the wiper arm 10 by the fastening force of the nut 16. It is the part which directly contacts with.

상기 너트(16)와 압착링(15)은 각각 별개로 성형한 후, 강제 끼워맞춤 방식으로 결합시켜 일체식으로 제작한다.The nut 16 and the pressing ring 15 are molded separately, and then integrally manufactured by joining in a forced fit method.

이를 위하여, 너트(16)의 하단 둘레부위와 압착링(15)의 내경측에 각각 쐐기형 걸림체(17)를 형성하여 결합 후 이것들이 상하방향으로 서로 맞걸려지게 함으로써, 서로 간의 분리가 방지되면서 자체 축선방향으로는 자유롭게 회전될 수 있게 된다.To this end, by forming a wedge-shaped locking body 17 on the lower circumferential portion of the nut 16 and the inner diameter side of the pressing ring 15, respectively, after they are engaged, they are engaged with each other in the vertical direction, thereby preventing separation from each other. It can be rotated freely in its own axial direction.

따라서, 본 발명의 기술을 적용하여 와이퍼 시스템(13)에 와이퍼 암(10)을 체결하는 방법에 대해 살펴보면 다음과 같다.Accordingly, a method of fastening the wiper arm 10 to the wiper system 13 by applying the technique of the present invention is as follows.

작업자가 일반공구 또는 전동공구를 가지고 와이퍼 암(10)을 체결할 때, 일체식의 압착링(15)과 너트(16)는 아래 방향으로 진행하고, 압착링(15)은 와이퍼 암(10)의 표면과 접촉하는 동시에 고정되고, 너트(16)는 계속 회전을 하여 압착링(15)을 누르면서 피봇(14)에 체결된다.When the operator engages the wiper arm 10 with a general tool or a power tool, the integral pressing ring 15 and the nut 16 move downward, and the pressing ring 15 moves the wiper arm 10. It is fixed at the same time in contact with the surface of the nut 16, the nut 16 is rotated to be fastened to the pivot 14 while pressing the pressing ring 15.

이에 따라, 소정의 체결 토크를 가하기 위해 너트(16)를 계속해서 조여도 압착링(15)은 고정된 상태로 와이퍼 암(10)을 누르고 있게 되므로, 와이퍼 암(10)의 페인트가 벗겨지는 등의 품질문제는 발생하지 않게 된다.Accordingly, even if the nut 16 is continuously tightened to apply a predetermined tightening torque, the pressing ring 15 is held in the fixed state so that the paint on the wiper arm 10 is peeled off. No quality problem occurs.

이상에서와 같이 본 발명은 와이퍼 암의 체결시 일정한 토크 이상이 되면 자체적으로 헛돌 수 있는 이중구조의 캡 너트를 채용한 와이퍼 암 체결구조를 제공함으로써, 체결시 과도한 체결 토크가 가해지는 경우에도 와이퍼 암의 페인트가 벗겨지는 등의 품질문제를 해결할 수 있는 효과가 있는 것이다.As described above, the present invention provides a wiper arm fastening structure employing a dual-cap cap nut that can turn itself when a certain torque is exceeded when the wiper arm is tightened, so that even when excessive tightening torque is applied during fastening, It is effective to solve quality problems such as peeling paint.
