Abstract
본 고안은 자동차의 리어엔드부 보강구조에 관한 것으로, 리어엔드패널(1)의 상부에 보강부재(2)와 상측리어엔드멤버(3)가 차례로 취부되어 2개의 폐단면이 형성되고, 상기 리어엔드패널(1)의 아래쪽 끝부분과 상기 상측리어엔드멤버(3)의 중간부분에 하측리어엔드멤버 (4)의 양측이 취부되어 하나의 폐단면이 형성되는 구조로 되어 리어엔드부의 강성이 향상되어 추돌시 충격흡수력이 향상되고 비틀림강성도 향상되게 되었다.The present invention relates to a reinforcement structure of a rear end portion of an automobile, wherein a reinforcement member 2 and an upper rear end member 3 are sequentially mounted on an upper portion of the rear end panel 1 to form two closed cross sections. Both ends of the lower rear end member 4 are attached to the lower end portion of the end panel 1 and the middle portion of the upper rear end member 3 to form a closed cross section, thereby improving the rigidity of the rear end portion. As a result, the impact absorption and the torsional stiffness are improved.
Description
본 고안은 자동차의 리어엔드(rear end)부 보강구조에 관한 것으로, 특히 패널수를 증가시키고 이 패널들이 상호 3중의 폐단면구조를 이루게 되어 충돌 및 비틀림에 대하 강성이 향상되도록 된 자동차의 리어엔드부 보강구조에 관한 것이다.The present invention relates to the reinforcement structure of the rear end of an automobile. In particular, the rear end of the automobile increases the number of panels and the panels form a triple closed cross-sectional structure to improve rigidity against collision and torsion. It relates to a secondary reinforcement structure.
일반적으로 자동차의 리어엔드부에는 리어범퍼가 구비되어 후방으로 부터의 충돌에 대해 차체를 보호하도록 되어 있지만 리어범퍼의 충격흡수효과에는 한계가 있으므로 자동차의 리어엔드부 자체도 충돌시의 충격과 주행시 자동차에 발생되는 비틀림에 대해 차체가 효과적으로 대응할 수 있도록 이루어져 있다.In general, the rear end of the car is equipped with a rear bumper to protect the body against a collision from the rear, but the shock absorbing effect of the rear bumper is limited. It is designed to effectively respond to the torsion generated in the car body.
한편, 종래 자동차의 리어엔드부 보강구조는 제2도에 도시된 바와 같이, 리어엔드패널(11;rear end panel)의 상부에 리어엔드멤버 (12;rear end member)가 용접되어 상기 리어엔드패널(11)의 상부에 하나의 폐단면이 형성되고, 이 리어엔드패널(11)과 리어앤드멤버(12)에 의해 이루어진 폐단면의 내부에 보강부재(13;reunf. striker)가 경사지게 용접되되, 이 보강부재(13)의 한쪽 끝부분은 상기 리어엔드패널 (11)과 리어엔드멤버(12)의 접합부 사이에 용접되고, 다른 한쪽 끝부분은 상기 리어엔드멤버(12)의 중간부분 절곡부에 용접되는 구조로 되어 있다.Meanwhile, as shown in FIG. 2, the rear end panel reinforcing structure of the conventional vehicle is welded to a rear end member 12 on an upper portion of the rear end panel 11. One closed cross section is formed on the upper portion of the eleven, and a reinforcing member 13 is inclinedly welded to the inside of the closed cross section formed by the rear end panel 11 and the rear end member 12. One end of the reinforcing member 13 is welded between the joint of the rear end panel 11 and the rear end member 12, and the other end of the reinforcing member 13 is bent at an intermediate portion of the rear end member 12. It is a structure to be welded.
따라서 리어엔드패널(11)의 상부에 강재의 패널들에 의해 2중패단면 구조가 형성되게 되어 후방으로 부터의 충격에 리어엔드부가 강성을 갖도록 되어 있으며, 차체에 발생되는 비틀림에도 대응할 수 있도록 되어 있다.Therefore, the double-sided cross-sectional structure is formed by the steel panels on the upper end of the rear end panel 11 so that the rear end portion has rigidity against the impact from the rear, and can cope with the torsion generated in the vehicle body. .
그러나 상기와 같은 구조의 리어엔드부 보강구조는 리어엔드패널(11)의 상부 즉 리어엔드부의 상부에만 폐단면 구조가 형성되어 있어서 평평한 리어엔드패널(11)의 하부 즉 리어엔드부의 하부는 별다른 강성보강구조가 적용되어 있지 못하므로 외부의 충격과 주행시 차체에 발생되는 비틀림에 대해 충분히 대응할 수 없게 되는 문제점이 있었다.However, the rear end reinforcement structure of the structure as described above has a closed cross-sectional structure formed only at the upper end of the rear end panel 11, that is, the upper end of the rear end portion, so that the lower portion of the flat rear end panel 11, that is, the lower end of the rear end portion, has a different rigid beam. Since the steel structure is not applied, there was a problem in that it could not sufficiently cope with external shock and torsion generated in the vehicle body during driving.
이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 리어엔드패널의 형상을 변경하고 리어엔드멤버를 상측리어엔드멤버와 하측리어엔드멤버로 분리하여 보강부재와 더불어 리어엔드부의 하부에 하나의 폐단면이 추가로 형성되는 즉 리어엔드부가 3중의 폐단면으로 이루어지도록 하여 내구강성과 비틀림강성이 한층 향상되도록 된 자동차의 리어엔드부 보강구조를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, by changing the shape of the rear end panel and separating the rear end member into an upper rear end member and a lower rear end member, and one of the rear end parts together with a reinforcing member. It is an object of the present invention to provide a rear end portion reinforcing structure of an automobile in which a closed end surface of the vehicle is additionally formed, that is, the rear end portion is made of a triple closed end surface, thereby further improving the oral resistance and torsional rigidity.

3:상측리어엔드멤버 4:하측리어엔드멤버3: upper rear end member 4: lower rear end member
상기와 같은 목적을 달성하기 위한 본 고안은, 상부가 후방으로 절곡된 리어엔드패널의 상부와 중간부에 경사지게 보강부재가 용접되고, 이 보강부재의 양쪽 끝부분에 후방으로 볼록하게 형성된 상측리어엔드멤버가 용접되며, 이 상측리어엔드멤버의 중간부분과 상기 리어엔드패널의 하측끝부분에 하측리어엔드멤버의 양측이 용접되는 구조로 되어 있다.The present invention for achieving the above object, the reinforcing member is welded inclined to the upper and middle portions of the rear end panel bent rearward, the upper rear end formed convexly at both ends of the reinforcing member The member is welded, and both sides of the lower rear end member are welded to the middle portion of the upper rear end member and the lower end portion of the rear end panel.
따라서 상기와 같은 구조의 리어엔드부에는 상부에 2개의 폐단면과 하부에 1개의 폐다면이 형성되어 강성이 일층 향상되게 된다.Therefore, the rear end portion of the structure as described above is formed with two closed end surfaces at the top and one closed side at the bottom to further improve rigidity.
이하 본 고안을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 따른 자동차의 리어엔드부 보강구조의 단면도로서, 본 고안은 대체적으로 평평한 패널의 상부가 차체의 후방으로 절곡된 형상으로 이루어진 리어엔드패널(1)과, 이 리어엔드패널(1)의 상측 끝부분과 중간부분에 경사지도록 양끝부분이 용접고정되는 보강부재(2)와, 이 보강부재(2)의 양끝부분 즉, 보강부재(2)의 리어엔드패널(1) 접합부위에 역시 양끝부분이 용접고정되는 상측리어엔드멤버(3)와, 이 리어엔드멤버(1)의 중간절곡부와 상기 리어엔드패널(1)의 하측끝부분에 양측이 고정되는 하측리어엔드멤버(4)로 구성되어 있다.1 is a cross-sectional view of a rear end portion reinforcing structure of a vehicle according to the present invention, the present invention is a rear end panel 1 made of a shape in which the upper portion of the generally flat panel is bent to the rear of the vehicle body, and the rear end panel ( On both ends of the reinforcing member 2, that is, on both ends of the reinforcing member 2, that is, on the joints of the rear end panel 1 of the reinforcing member 2, in which both ends are welded and fixed to be inclined to the upper end and the middle part of 1). The upper rear end member 3, in which both ends are fixed by welding, and the lower rear end member 4 in which both sides are fixed to the middle bent portion of the rear end member 1 and the lower end of the rear end panel 1, respectively. It consists of).
따라서 상기 리어엔드패널(1)의 상부와 보강부재(2)의 사이에 하나의 폐단면이 형성되고, 이 보강부재(2)와 상기 상측리어엔드멤버 (3)의 사이에 또 하나의 폐단면이 형성되며, 이 상측리어엔드멤버(3)의 하측으로 상기 리어엔드패널(1)의 중간이하부분과 상기 하측리어엔드멤버(4) 전체 및 상기 상측리어엔드멤버(3)의 하향면으로 둘러 쌓인 또 다른 하나의 폐단면이 형성되게 된다.Accordingly, one closed end surface is formed between the upper portion of the rear end panel 1 and the reinforcing member 2, and another closed end surface is formed between the reinforcing member 2 and the upper rear end member 3. Is formed, and surrounds the lower part of the rear end panel 3, the lower half of the rear end member 4, and the lower side of the upper rear end member 3, below the upper rear end member 3; Another stacked cross-section is formed.
따라서 상기 리어엔드부는 전체적으로 2부분의 수직부분을 4부분의 수평 및 경사부분이 지지하고 있는 형상으로 이루어져 후방으로 부터의 충격이 전해질시 충격흡수력이 매우 강하고, 전체적으로 차량의 가로부를 구상하는 패널의 수가 늘어나게 된 것이므로 차량의 회전주행시 발생되는 비틀림 강성에도 효과적으로대응할 수 있게 된다.Therefore, the rear end part has a shape in which two vertical parts are supported by four horizontal and inclined parts as a whole, so that the shock absorbing power is very strong when an impact from the rear is transmitted, and the number of panels that envision the horizontal part of the vehicle as a whole Since it is increased, it is possible to effectively cope with the torsional rigidity generated when the vehicle is rotating.
이상 설명한 바와 같이 본 고안에 따르면, 리어엔드부의 강성이 보강되어 차량의 후면충돌시 충격흡수성능이 향상되고, 비틀림강성이 향상되어 자동차의 안전성이 향상되게 되는 효과가 있다.As described above, according to the present invention, the rigidity of the rear end portion is reinforced to improve the shock absorbing performance during the rear collision of the vehicle, and the torsional rigidity is improved, thereby improving the safety of the vehicle.
