승용차 도어의 임팩트 빔{Impact beam in vehicle's door}Impact beam in vehicle's door

본 발명은 차량 도어에 설치되는 임팩트빔에 관한 것으로서, 특히 차량의 측면에서 충격이 발생할 경우 일정 이상의 충격일 경우에는 임팩트 빔 자체가 파손되도록 하여 임팩트 빔이 차량의 내부로 밀려들어와 탑승자에게 부상을 입히는 것을 방지할 수 있도록 한 승용차 도어의 임팩트 빔에 관한 것이다.The present invention relates to an impact beam installed in a vehicle door, and in particular, in the event of an impact from the side of the vehicle, the impact beam itself is damaged when the impact beam itself is damaged so that the impact beam is pushed into the vehicle to injure the occupant It relates to an impact beam of a passenger car door that can be prevented.

도 1은 일반적인 차량의 일실시예를 나타내는 측면도로서, 차량의 도어에는 차량의 외부 즉, 차량의 측면에서 충격이 전해질 때 탑승자를 보호할 수 있는 임팩트빔(1)이 설치되어 있음을 알 수 있다.1 is a side view showing an embodiment of a general vehicle, it can be seen that the impact beam (1) to protect the occupant when the impact from the outside of the vehicle, that is, the side of the vehicle is installed. .

도 2는 임팩트빔에 충격이 전해졌을 때의 상태를 나타내는 도면으로서, 차량의 측면에서 충격이 전해졌을 때 도어의 전후 필라에 걸쳐서 설치되어 있는 임팩트빔(1)의 일측이 차량의 내부로 밀려들어오게 되고, 이에 따라 차량에 탑승한 승객은 밀려들어온 임팩트 빔에 의하여 부상을 입는 문제점이 있었다.FIG. 2 is a view showing a state when an impact is transmitted to the impact beam. When an impact is transmitted from the side of the vehicle, one side of the impact beam 1 provided over the front and rear pillars of the door is pushed into the vehicle. As a result, the passengers in the vehicle were injured by the impact beams.

본 발명은 상기한 문제를 해결하기 위한 것으로서, 차량 도어의 임팩트 빔에 일정한 크기의 충격 흡수 구조를 형성시켜 외부에서 전해지는 충격이 일정이상일 경우에는 임팩트빔이 스스로 파손되도록 하여 탑승자에게 전해지는 충격량을 흡수하도록 한 승용차 도어의 임팩트 빔을 제공하는 것을 목적으로 한다.The present invention is to solve the above problems, by forming a shock-absorbing structure of a certain size on the impact beam of the vehicle door, when the impact transmitted from the outside is a certain amount to the impact beam to be broken by itself to the impact amount transmitted to the occupant It is an object to provide an impact beam of a passenger car door that is adapted to absorb.

상기 목적을 달성하기 위해 본 발명 승용차 도어의 임팩트 빔은, 차량의 도어 내측에 전후 필라에 걸쳐 설치되는 임팩트빔에 있어서, 임팩트빔의 일측에 일정 이상의 충격이 가해질 때 임팩트 빔이 파손되도록 하는 충격 흡수 구조를 형성시켜 구성되는 것을 특징으로 한다.In order to achieve the above object, the impact beam of the passenger car door of the present invention, in the impact beam installed in the front and rear pillars inside the door of the vehicle, the shock absorbing to damage the impact beam when a predetermined or more impact is applied to one side of the impact beam It is characterized by forming a structure.

도 3a는 본 발명에 따른 승용차 도어의 임팩트 빔의 일실시예를 나타내는 측면도로서, 그 구성과 작용을 설명하면 다음과 같다.Figure 3a is a side view showing an embodiment of the impact beam of a passenger car door according to the present invention, the configuration and operation will be described as follows.

도어의 내부에 설치되는 임팩트 빔(10)의 소정의 장소에 회전식 전기톱 등을 이용하여 임팩트 빔(10)의 중심축에 대하여 수직인 방향으로 일정 길이의 절단홈(15)을 다수개 형성시키도록 한다. 이러한 작업은 도어 내부에 임팩트 빔을 설치하기 전에 실시하는 것이 바람직하다.A plurality of cutting grooves 15 having a predetermined length are formed in a direction perpendicular to the central axis of the impact beam 10 by using a rotary saw or the like at a predetermined place of the impact beam 10 installed inside the door. To do that. This is preferably done before installing the impact beam inside the door.

도 3a에 도시되어 있는 실시예에서는 2개의 절단홈(15)이 형성되어 있음을 알 수 있으나, 절단홈의 갯수와 길이는 필요에 따라 가변할 수 있다.In the embodiment shown in FIG. 3A, it can be seen that two cutting grooves 15 are formed, but the number and length of the cutting grooves can be varied as necessary.

상기와 같은 임팩트빔이 도어에 설치되었을 때, 차량의 측면에서 충격이 가해질 경우 측면에서 발생된 충격이 미약한 경우에는 충격이 임팩트빔(10)에 흡수되어 승객을 보호하게 된다.When the impact beam is installed in the door, when the impact is applied from the side of the vehicle, when the impact generated from the side is weak, the impact is absorbed by the impact beam 10 to protect the passenger.

그러나 임팩트빔에 흡수될 수 없는 정도의 충격량일 경우 임팩트빔(10)의 절단홈(15)부분이 파손되어 도 3b에 도시되어 있는 바와 같이 임팩트빔(10)이 파손되어, 임팩트빔이 차량의 내부로 밀려들어와 승객(20)에게 부상을 입히는 경우가 방지된다.However, when the impact amount is not absorbed by the impact beam, the cutting groove 15 of the impact beam 10 is broken and the impact beam 10 is broken as shown in FIG. The case of being pushed inside and causing injury to the passenger 20 is prevented.

도 4a는 발명에 따른 승용차 도어의 임팩트 빔의 다른 일실시예를 나타내는 측면도로서, 그 구성과 작용을 설명하면 다음과 같다.Figure 4a is a side view showing another embodiment of the impact beam of a passenger car door according to the invention, the configuration and operation will be described as follows.

도어의 내부에 설치되는 임팩트 빔(40)의 소정의 장소에 드릴 등을 이용하여 다수개의 홀(45)이 형성되도록 한다. 도면에 도시되어 있는 실시예에서는 4개의홀(45)이 형성되어 있음을 알 수 있으나, 홀의 갯수와 지름은 필요에 따라 가변할 수 있다.A plurality of holes 45 are formed in a predetermined place of the impact beam 40 installed inside the door by using a drill or the like. In the embodiment shown in the figure it can be seen that the four holes 45 are formed, but the number and diameter of the holes can be varied as needed.

상기와 같은 임팩트빔(40)이 도어에 설치되었을 때, 차량의 측면에서 충격이 가해질 경우 측면에서 발생된 충격이 미약한 경우에는 임팩트빔에 의해 충격이 흡수되지만, 차량의 측면에서 충격이 가해질 경우 측면에서 발생된 충격이 임팩트빔(40)에 흡수되어 승객을 보호하게 된다.When the impact beam 40 is installed in the door, when the impact is applied from the side of the vehicle, the impact is absorbed by the impact beam when the impact generated from the side is weak, but the impact is applied from the side of the vehicle The impact generated from the side is absorbed by the impact beam 40 to protect the passengers.

그러나 임팩트빔(40)에 의해 흡수될 수 없는 정도의 충격량일 경우 도 4b에 도시되어 있는 바와 같이 임팩트빔(40)의 홀(45)부분을 중심으로 임팩트빔(40)이 파손되어 임팩트빔이 차량의 내부로 밀려들어와 승객(20)에게 부상을 입히는 경우가 방지된다.However, when the impact amount is not absorbed by the impact beam 40, as shown in Figure 4b the impact beam 40 is broken around the hole 45 portion of the impact beam 40, the impact beam The case of being pushed into the vehicle and injuring the passenger 20 is prevented.

상기한 바와 같이 구성된 본 발명은 차량의 도어에 설치되는 임팩트빔의 일정 장소에 일정 이상의 충격이 가해질 경우 임팩트 빔이 파손될 수 있도록 하는 구조를 형성시켜 차량의 측면에서 일정 이상의 충격이 발생될 경우 임팩트빔이 차량 내부로 밀려들어와 승객에게 부상을 입히는 경우를 방지하게 된다.The present invention configured as described above forms a structure that allows the impact beam to be broken when a predetermined or more impact is applied to a predetermined place of the impact beam installed in the door of the impact beam when a predetermined or more impact is generated from the side of the vehicle. This prevents them from being pushed into the vehicle and causing injury to passengers.
