[산업상의 이용분야][Industrial use]
본 고안은 충격흡수력이 향상된 범퍼구조에 관한 것으로서, 더욱 상세하게는 에어실린더를 장착한 충격흡수력이 향상된 범퍼구조에 관한 것이다.The present invention relates to a bumper structure with improved shock absorption, and more particularly, to a bumper structure with improved shock absorption with an air cylinder.
[종래의 기술][Prior art]
자동차에 있어서 범퍼는 자동차가 충돌할 때의 충격을 흡수하여 운전자 및 승차자의 안전을 확보하기 위한 것이다.Bumpers in automobiles are for absorbing the impact when a vehicle collides to ensure the safety of drivers and riders.
종래의 자동차용 범퍼는 범퍼카버와, 상기한 범퍼카버 안에 충전된 완충부재에 의하여 충격을 흡수하고 있다.Conventional automobile bumpers absorb shocks by a bumper cover and a buffer member filled in the bumper cover.
상기와 같이 구성된 종래의 범퍼는 충돌에 대한 충격력흡수가 불충분하여 차동차의 손상 및 승차자의 안전에 문제가 있다.The conventional bumper configured as described above has a problem of damage to the differential vehicle and safety of the occupant due to insufficient impact force absorption against a collision.
[과제를 해결하기 위한 수단][Means for solving the problem]
상기와 같은 문제를 해결하기 위하여 본 고안이 강구한 수단은 범퍼카버와, 상기한 범퍼카버에 고정되는 범퍼고정판과, 상기한 범퍼고정판에 한쪽이 고정되는 범퍼브라케트와, 차체에 부착되는 차체고정판과, 상기한 범퍼브라케트의 다른쪽을 상기한 차체고정판에 회전가능하게 고정하는 회전축과, 상기한 회전축에 설치되는 회전스프링과, 상기한 범퍼브라케트의 중앙부에 부착되는 로드고정부와, 상기한 로드고정부에 한쪽이 고정되는 로드와, 상기한 로드의 다른쪽에 결합되는 피스톤과, 상기한 피스톤을 감싸는 실린더와, 상기한 실린더의 피스톤 반대쪽에 설치되고 공기배출구멍이 형성된 배출플러그와, 상기한 실린더가 고정되고 차체에 설치되는 실린더고정판을 포함하는 충격흡수력이 향상된 범퍼구조를 제공하는 것이다.Means devised in order to solve the above problems are the bumper cover, the bumper fixing plate fixed to the bumper cover, the bumper bracket one side is fixed to the bumper fixing plate, body fixing plate attached to the vehicle body And a rotating shaft rotatably fixing the other side of the bumper bracket to the vehicle body fixing plate, a rotating spring installed on the rotating shaft, and a rod fixing part attached to a central portion of the bumper bracket. A rod fixed to one rod fixing part, a piston coupled to the other side of the rod, a cylinder surrounding the piston, a discharge plug provided on an opposite side of the piston of the cylinder and having an air discharge hole; It is to provide a bumper structure with improved shock absorbing power including a cylinder fixing plate fixed to one cylinder and installed in the vehicle body.
상기한 실린더 내부에는 공기가 채워져 있다.The cylinder is filled with air.
[기능 및 작용][Functions and actions]
상기와 같이 구성된 본 고안 충격흡수력이 향상된 범퍼구조는 자동차가 충돌할 때에, 회전축을 중심으로 회전스프링의 힘과 범퍼브라케트를 통하여 전달된 힘이 피스톤을 밀게 되고, 피스톤을 미는 힘에 따라 실린더내의 공기가 배출플러그의 공기배출구멍을 통하여 배출된다.The bumper structure of the present invention, which is configured as described above, has improved impact absorbing force, when a vehicle collides, the force of the rotating spring and the force transmitted through the bumper bracket around the rotating shaft push the piston and push the piston into the cylinder. Air is discharged through the air discharge hole of the discharge plug.
상기한 공기배출구멍의 크기가 작기 때문에, 충격력이 크면 실린더내의 공기가 일시에 빠져나가지 못하므로 오히려 로드에 연결된 범퍼브라케트가 범퍼카버를 밀게 된다. 반대로 충격력이 작으면 실린더내의 공기가 자연스럽게 빠져나가게 된다.Since the air discharge hole is small in size, if the impact force is large, the air in the cylinder does not escape at a time, so the bumper bracket connected to the rod pushes the bumper cover. On the contrary, when the impact force is small, the air in the cylinder is naturally released.
[실시예]EXAMPLE
다음으로 본 고안 충격흡수력이 향상된 범퍼구조의 가장 바람직한 실시예를 도면을 참조하여 상세하게 설명한다.Next, the most preferred embodiment of the bumper structure with improved shock absorption of the present invention will be described in detail with reference to the accompanying drawings.
먼저 제1도에 나타낸 바와 같이, 본 고안 충격흡수력이 향상된 범퍼구조의 일실시예는 범퍼카버(4)와, 상기한 범퍼카버(4)에 고정되는 범퍼고정판(6)과, 상기한 범퍼고정판(6)에 한쪽이 고정되는 범퍼브라케트(12)와, 차체(2)에 부착되는 차체고정판(10)과, 상기한 범퍼브라케트(12)의 다른쪽을 상기한 차체고정판(10)에 회전가능하게 고정하는 회전축(11)과, 상기한 회전축(11)에 설치되는 회전스프링(14)과, 상기한 범퍼브라케트(12)의 중앙부에 부착되는 로드고정부(16)와, 상기한 로드고정부(16)에 한쪽이 고정되는 로드(20)와, 상기한 로드(20)의 다른쪽에 결합되는 피스톤(22)과, 상기한 피스톤(22)을 감싸는 실린더(18)와, 상기한 실린더(18)의 피스톤(22) 반대쪽에 설치되고 공기배출구멍이 형성된 배출플러그(24)와, 상기한 실린더(18)가 고정되고 차체(2)에 설치되는 실린더고정판(8)을 포함한다.First, as shown in FIG. 1, one embodiment of the bumper structure of the present invention with improved shock absorbing force is a bumper cover 4, a bumper fixing plate 6 fixed to the bumper cover 4, and the bumper fixing plate. The bumper bracket 12 fixed to one side 6, the vehicle body fixing plate 10 attached to the vehicle body 2, and the other of the bumper bracket 12 described above are attached to the vehicle body fixing plate 10 described above. A rotating shaft 11 rotatably fixed, a rotating spring 14 provided on the rotating shaft 11, a rod fixing portion 16 attached to the center of the bumper bracket 12, and The rod 20 fixed to the rod fixing part 16, the piston 22 coupled to the other side of the rod 20, the cylinder 18 surrounding the piston 22, and the A discharge plug 24 provided on the opposite side of the piston 22 of the cylinder 18 and the air discharge hole is formed, and a seal in which the cylinder 18 is fixed and installed in the vehicle body 2. The lining fixing plate 8 is included.
상기한 실린더(18) 내부에는 공기가 채워져 있다.The cylinder 18 is filled with air.
상기와 같이 구성된 본 고안 충격흡수력이 향상된 범퍼구조는 자동차가 충돌할 때에, 회전축(11)을 중심으로 회전스프링(14)의 힘과 범퍼브라케트(4)를 통하여 전달된 힘이 피스톤(22)을 밀게 되고, 피스톤(22)을 미는 힘에 따라 실린더(18)내의 공기가 배출플러그(24)의 공기배출구멍을 통하여 배출된다.The bumper structure of the present invention having improved shock absorbing force configured as described above has a piston 22 having a force of the rotating spring 14 and a force transmitted through the bumper bracket 4 about the rotating shaft 11 when the vehicle collides. The air in the cylinder 18 is discharged through the air discharge hole of the discharge plug 24 according to the force pushing the piston 22.
상기한 공기배출구멍의 크기가 작기 때문에, 충격력이 크면 실린더(18)내의 공기가 일시에 빠져나가지 못하므로 오히려 로드(20)에 연결된 범퍼브라케트(12)가 범퍼카버(4)를 밀게 된다. 반대로 충격력이 작으면 실린더(18)내의 공기가 배출플러그(24)의 공기배출구멍을 통하여 자연스럽게 빠져나가게 된다.Since the air discharge hole is small in size, when the impact force is large, the air in the cylinder 18 does not temporarily escape, and the bumper bracket 12 connected to the rod 20 pushes the bumper cover 4. On the contrary, when the impact force is small, the air in the cylinder 18 naturally escapes through the air discharge hole of the discharge plug 24.
[고안의 효과][Effect of design]
상기와 같이 구성되고 작동되는 본 고안 충격흡수력이 향상된 범퍼구조를 사용하면, 자동차가 충돌할 때에 받는 충격력을 종래의 범퍼카버와 완충부재에서 흡수할뿐만 아니라 실린더내의 공기를 통하여도 흡수하므로 안전성이 향상된다.When the bumper structure of the present invention, which is constructed and operated as described above, is improved, the impact force received when a vehicle collides is absorbed not only by the conventional bumper cover and the buffer member but also by the air in the cylinder, thereby improving safety. do.
