Description

스티어링 휠의 링 커버 구현방법{Obtaining method of ring cover of steering wheel}Observing method of ring cover of steering wheel}

본 발명은 스티어링 휠의 링 커버 구현방법에 관한 것으로서, 이를 보다 구체적으로 설명하자면 스티어링 휠의 링 외주에 구성되는 링 커버를 조립식으로 구현하여 제조의 편의성과 더불어 불량감소 및 대량 생산을 꾀하도록 하고 나아가 상기 커버를 특정 재질로 제작하여 스티어링 휠의 링 파지 감을 향상시킴은 물론 그 무게를 현저히 감소토록 하였다. The present invention relates to a method for implementing a ring cover of a steering wheel, to describe in more detail to implement the ring cover configured on the ring outer periphery of the steering wheel in a prefabricated manner to reduce defects and mass production as well as convenience of manufacturing The cover is made of a specific material to improve the ring grip of the steering wheel as well as to significantly reduce its weight.

첨부된 도면 도 3에서와 같이 종래 스티어링 휠의 링(1) 외주에 피복되는 링커버(11)는 스티어링 휠의 링(1)을 금형틀(2)에 안치하여 우레탄 발포제로 발포성형함으로 스티어링 휠의 링(1) 외주에 일체로 구성토록 하고 있다. As shown in FIG. 3, the ring cover 11 coated on the outer circumference of the ring 1 of the conventional steering wheel is placed on the mold 1 of the steering wheel and foamed with urethane foam to form the steering wheel. It is made to be integrally formed with the outer periphery of the ring (1).

여기서, 상기 링 커버(11)는 차량용 스티어링 휠(101)의 파지 감을 향상시킴과 동시에 운전자와 스티어링 휠(101)의 충돌시, 그 충격을 완화시켜 안전사고의 안전을 도모토록 하기 위한 것이다. Here, the ring cover 11 is to improve the grip feeling of the steering wheel 101 for the vehicle and at the same time to mitigate the impact when the driver and the steering wheel 101 collide, to ensure the safety of the safety accident.

그러나, 위와 같은 구현되는 스티어링 휠의 링 커버는 스티어링 휠을 금형틀에 안치하여 발포/성형으로 커버를 링 외주에 일체화구성시키는 방법으로 그 작업이 매우 난이 함은 물론 발포/성형 후 건조 및 커버의 마무리(다듬는 공정)과정을 순차적으로 거쳐야 하는 문제를 가지고 있어, 생산성 및 작업의 효율성이 떨어지는 문제를 가지고 있었고, However, the ring cover of the steering wheel implemented as described above is a method of integrally configuring the cover on the outer circumference of the ring by placing the steering wheel in the mold and foaming / molding. Had the problem of going through the finishing process (slicing process) in sequence, and had the problem of low productivity and work efficiency,

특히 상기 스티어링 휠의 링 커버는 그 발포/성형시 발포제의 주입불량에 의해 커버의 형상 불량이 매우 많았는데, 이러한 커버의 불량발생시 종래에는 커버가 스티어링 휠의 링과 일체 제조됨에 따라, 스티어링 휠 전체를 폐기하여야 하는 손실을 가지고 있었다. In particular, the ring cover of the steering wheel has a large number of shape defects due to the improper injection of the foaming agent during the foaming / molding. In the case of such a cover failure, the steering wheel as a whole is manufactured integrally with the ring of the steering wheel. Had a loss that must be discarded.

본 발명은 상기와 같은 종래 문제를 해결하기 위하여 발명된 것으로서, 특히상기 스티어링 휠의 링 외주에 구성되는 링 커버를 발포폴리프로필렌(이하'EPP'라 칭함)재질로 구성토록 함과 동시에 상기 링 커버를 상,하부 커버로 분할하여 하부 커버는 스티어링 휠의 링에 일체로 발포/성형토록 하고 상기 상부 커버는 별도 제작후 스티어링 휠의 링에 결합/부착토록 하였다. The present invention has been invented to solve the above-mentioned conventional problems, and in particular, the ring cover formed on the outer periphery of the ring of the steering wheel is made of foamed polypropylene (hereinafter referred to as 'EPP') material and at the same time the ring cover The upper and lower cover was divided into a lower cover to be integrally foamed / molded on the ring of the steering wheel, and the upper cover was coupled to / attached to the ring of the steering wheel after a separate production.

그러면, 상기 스티어링 휠의 링으로 링커버의 구성시 스티어링 휠과는 별개 로 상부커버를 제작할 수 있어, 작업의 효율 및 생산성 증가를 꾀할 수 있게 되고 나아가 링커버의 불량 시 스티어링 휠로부터 커버의 교체작업이 가능해지는 이점을 가지게 된다. Then, the upper cover can be manufactured separately from the steering wheel when the ring cover is configured by the ring of the steering wheel, so that the efficiency and productivity of the work can be increased, and further, the replacement work of the cover from the steering wheel when the ring cover is defective. This has the advantage of being possible.

위와 같은 과제를 해결하기 위한 본 발명의 수단으로는 As a means of the present invention for solving the above problems

첨부된 도면 도 1에서와 같이 스티어링 휠의 링(1) 외주로 링커버(11)를 구성토록 하는 스티어링 휠의 링 커버 구현방법에 있어서, In the accompanying drawings, a method of implementing a ring cover of the steering wheel to configure the ring cover 11 around the ring 1 of the steering wheel as shown in FIG. 1,

상기 링 커버(11)를 EPP(발포폴리프로필렌)재질을 이용하여 상,하부 커버(11a)(11b)로 구성하되, 상기 하부커버(11b)는 스티어링 휠의 링(1) 하부에 발포/성형하여 일체로 구성하고, 상기 상부커버(11a)는 하부커버(11b)와 달리 개별제작한 다음 상기 스티어링 휠의 링(1) 상부에 조립하여 하부커버(11b)와 접착제로 부착고정토록 하였다. The ring cover 11 is composed of upper and lower covers 11a and 11b using EPP (foamed polypropylene) material, and the lower cover 11b is foamed / molded under the ring 1 of the steering wheel. The upper cover 11a was manufactured separately from the lower cover 11b, and then assembled to the upper part of the ring 1 of the steering wheel, and fixed to be attached with the lower cover 11b and an adhesive.

따라서 본 발명은 스티어링 휠의 링 커버를 상,하부 커버로 분할하여 스티어링 휠의 링에 조립구성토록 한 것으로서, Therefore, in the present invention, the ring cover of the steering wheel is divided into upper and lower covers to be assembled to the ring of the steering wheel.

스티어링 휠과는 별개로 상기 상부커버를 대량 제작할 수 있어, 스티어링 휠의 생산효율성 증대 및 작업효율성의 증대를 꾀할 수 있게 되고, 더욱이 상기 링 커버를 스티어링 휠과 별도 제작하여 조립토록 하므로 종래 커버 문제로 인한 스티 어링 휠의 불량률 발생을 초기에 방지하여 줌은 물론 필요 시 커버를 교체할 수 있는 이점까지 가지게 되어, 스티어링 휠의 폐기처분시 발생되는 막대한 비용적 손실을 현저히 막아줄 수 있게 된다. The upper cover can be manufactured in a large quantity separately from the steering wheel, so that the production efficiency of the steering wheel can be increased and the work efficiency can be increased. Furthermore, the ring cover can be manufactured separately from the steering wheel to be assembled and assembled so as to cover the conventional cover. By preventing the initial failure rate of the steering wheel due to the zoom, as well as having the advantage of replacing the cover if necessary, it is possible to significantly prevent the enormous cost loss in the disposal of the steering wheel disposal.

이를 보다 구체적으로 설명하자면 아래와 같다.This will be described in more detail below.

스티어링 휠의 링 커버 구현을 위해서 본 발명은,The present invention for implementing a ring cover of the steering wheel,

먼저 스티어링 휠의 링(1)에 구현되는 링 커버(11)를 상,하부커버(11a)(11b)로 분할하여 구성하되, First, the ring cover 11 implemented in the ring 1 of the steering wheel is divided into upper and lower covers 11a and 11b,

상기 하부커버(11b)는 스티어링 휠의 링(1)하부에 발포/성형으로 일체 구성하고,The lower cover 11b is integrally formed by foaming / molding under the ring 1 of the steering wheel,

상기 상부커버(11a)는 스티어링 휠(101)과 별개로 개별 제작한 후 이를 하부커버(11b)가 일체 구성되어져 있는 스티어링 휠의 링(1)상부에 조립하여 하부커버(11b)와 접착제로 부착고정시킨다.The upper cover 11a is manufactured separately from the steering wheel 101 and then assembled to the upper part of the ring 1 of the steering wheel in which the lower cover 11b is integrally attached and attached to the lower cover 11b and an adhesive. Fix it.

여기서, 개별제작되는 상부커버는 그 내부로 반원형상의 삽입부를 가지는 것으로 종래에 스티어링 휠의 링에 일체로 발포/성형하였던 커버와 동일 형상을 가진다.Here, the individually manufactured upper cover has a semicircular insert portion therein, and has the same shape as the cover which was conventionally foamed / molded integrally with the ring of the steering wheel.

또한 상기 상,하부커버는 종래에 사용되었던 우레탄 재질보다 가벼운 EPP재 질로 발포/성형한다. In addition, the upper and lower covers are foamed / molded with EPP material which is lighter than the urethane material used in the related art.

따라서, 본 발명은 상기에서와 같이 스티어링 휠의 링으로 하부 커버는 일체형으로 구성하고 상부커버는 조립식으로 구성한 것으로, Therefore, the present invention is configured as a lower cover is integrally configured as a ring of the steering wheel and the upper cover is assembled as described above,

스티어링 휠과 스티어링 휠의 링 커버를 개별적으로 분할 제작하여 스티어링 휠과 스티어링 휠의 링 커버가 단시간 내에 대량 제작이 가능하여지도록 하고 나아가 스티어링 휠의 링으로 커버를 일체구성이 아닌 조립구성으로 구현하여 커버의 불량으로 인한 스티어링 휠의 전체 폐기를 막아 줌은 물론 커버의 불량 발생시, 일부 커버를 교체작업가능케 하여 원자재의 낭비를 막음은 물론 그에 따른 비용적 손실을 방지하여 주도록 하였다.The steering wheel and the ring cover of the steering wheel are separately manufactured to enable mass production of the steering wheel and the ring cover of the steering wheel in a short time, and furthermore, the cover of the steering wheel is implemented as an assembly instead of an integrated configuration. In addition to preventing the entire disposal of the steering wheel due to the poor quality of the cover, when the cover is defective, some covers can be replaced to prevent waste of raw materials and to prevent the cost loss.

또 상기 스티어링 휠의 링으로 커버를 일체형으로 구현하지 않고 조립식으로 구현할 경우 커버를 다양한 형상과 색으로 표현할 수 있어 그 외관을 보다 미려하게 하여 주는 이점까지 제공하게 된다. In addition, when the cover is implemented in a prefabricated manner without implementing the cover integrally with the ring of the steering wheel, the cover may be expressed in various shapes and colors, thereby providing an advantage of making the appearance more beautiful.
