Description
본 발명은 화물자동차 범퍼의 코너부결합구조에 관한 것으로, 더욱 상세하게 설명하면 화물자동차 범퍼의 코너부가 측면 충돌에 대하여 완충될 수 있도록 된 화물자동차 범퍼의 코너부결합구조에 관한 것이다.The present invention relates to a corner portion coupling structure of a lorry bumper, and more particularly, to a corner portion coupling structure of a lorry bumper, which allows the corner portion of the lorry bumper to be buffered against side collisions.
일반적으로, 모든 자동차 전면과 후면에는 충돌사고 발생될 때 차체 손상을 최소화하기 위하여 범퍼가 구비되어 있고, 이 범퍼는 차종에 따라 다양한 구조를 가지고 있다.In general, all the front and rear of the vehicle is provided with a bumper to minimize the damage to the body when a crash occurs, the bumper has a variety of structures depending on the model.
이러한 범퍼구조 중 승용차의 경우에는 범퍼의 내측에 충격흡수용 완충부재가 구비되어 있으며, 상기 범퍼가 일체로 차체에 고정되어 있다.Among such bumper structures, in the case of a passenger car, a shock absorbing shock absorbing member is provided inside the bumper, and the bumper is integrally fixed to the vehicle body.
그리고, 화물자동차의 경우에는 도 1에 도시된 바와같이 "ㄷ"자형으로 단순절곡 형성된 범퍼(50)가 차체에 고정되고, 이 범퍼(50)의 양측에는 접촉사고가 발생되었을 때 상기 범퍼(50)와 피 접촉자동차의 손상을 최소화 할 수 있도록 합성수지재로 사출성형된 코너부(60)가 구비되며, 이 코너부(60)의 내측에는 상기 코너부(60)를 범퍼(50)의 양측에 고정시킬 수 있도록 결합된 코너브래킷(61)이 상기 범퍼(50)에 융착고정되어 있다.And, in the case of a lorry, as shown in FIG. 1, the bumper 50, which is simply bent into a "c" shape, is fixed to the vehicle body, and when the contact accident occurs on both sides of the bumper 50, the bumper 50 And a corner part 60 which is injection molded with a synthetic resin material to minimize damage of the to-be-contacted vehicle, and the corner part 60 is provided on both sides of the bumper 50 inside the corner part 60. Corner brackets 61 coupled to be fixed are fusion-fixed to the bumper 50.
상기한 바와같이 구성된 화물자동차의 범퍼(50)의 코너부(60)는, 운행 중 운전자의 부주의 등으로 인하여 접촉사고가 발생되면, 접촉사고로 인한 외력이 코너부(60)에 작용되어 변형 또는 파손되므로 미관이 저하된다.In the corner portion 60 of the bumper 50 of the freight vehicle configured as described above, if a contact accident occurs due to carelessness of the driver during driving, an external force due to the contact accident is applied to the corner portion 60 to deform or Because it is broken, the appearance is degraded.
그러나, 대부분의 운전자들은 상술한 바와같이 작은 접촉사고에도 코너부(60)가 파손되어 운전자에게 경제적 손실이 따르게 되므로 이를 교환하지 않고 운행하게 되어 미관이 저하됨은 물론, 파손 또는 변형에 의하여 외부로 돌출된 코너부(60)가 타 자동차의 몸체를 손상시키는 제2의 접촉사고를 유발시킨다.However, most of the drivers, as described above, the corner portion 60 is damaged even in a small contact accident, which causes economic loss to the driver, so that the driver may operate without replacing it, deteriorating aesthetics, and protruding to the outside by damage or deformation. Corner portion 60 causes a second contact accident that damages the body of another vehicle.
이에 본 발명은 상술한 문제점을 해결하기 위하여 창출된 것으로, 접촉사고가 발생되었을 때 화물자동차 범퍼의 코너부가 측면 충돌에 대하여 회동되어 완충작용을 할 수 있도록 함을 본 발명의 목적으로 한다.Therefore, the present invention was created to solve the above-mentioned problems, and it is an object of the present invention to allow the corner portion of the freighter bumper to be rotated with respect to the side collision when the accident occurs.

상기 목적을 달성하기 위한 본 발명의 구성은, 화물자동차의 범퍼의 양측 내면에 범퍼브래킷이 고정되고, 이 범퍼브래킷의 외측에는 코너부의 내측에 고정된 코너브래킷이 회동 가능하게 결합되도록 된 힌지부가 구비됨과 더불어 내측에는 스프링핀이 구비되며, 이 스프링핀에는 코너부가 탄성 지지되도록 된 비틀림스프링이 결합되는 한편, 상기 코너브래킷에는 내측으로 연장돌출되어 상기 비틀림스프링에 탄설되는 지지부가 형성되어 구성된 것이다.The configuration of the present invention for achieving the above object, the bumper bracket is fixed to the inner surface of both sides of the bumper of the lorry, the outer side of the bumper bracket is provided with a hinge portion such that the corner bracket fixed to the inside of the corner portion is rotatably coupled. In addition, the inner side is provided with a spring pin, the torsion spring is coupled to the spring pin so that the corner portion is elastically supported, while the corner bracket extends inward to the support portion is formed in the torsion spring is formed.
이하 첨부된 예시도에 의하여 구성에 대하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration in detail with reference to the accompanying drawings as follows.
도 2는 본 발명의 결합상태 단면도이고, 도 3은 본 발명의 작동상태 단면도로서, 본 발명에 따른 화물자동차 범퍼의 코너부결합구조는, 화물자동차의 범퍼(10)의 양측 내면에는 코너부(20)를 결합시킬 수 있도록 된 범퍼브래킷(11)이 고정되어있고, 이 범퍼브래킷(11)의 외측에는 코너부(20)의 내측에 고정된 코너브래킷(21)이 회동 가능하게 결합되도록 된 힌지부(12)가 구비됨과 더불어 내측 중앙에는 상기 코너부(20)를 탄성 지지할 수 있도록 된 비틀림스프링(13)이 결합되는 스프링핀(11a)이 구비되어 있다.Figure 2 is a cross-sectional view of the coupling state of the present invention, Figure 3 is a cross-sectional view of the operating state of the present invention, the corner portion coupling structure of the bumper truck according to the present invention, the corners ( The bumper bracket 11, which is capable of engaging 20, is fixed, and the outside of the bumper bracket 11, the corner bracket 21 fixed to the inside of the corner portion 20, is rotatably coupled. A branch 12 is provided and a spring pin 11a to which the torsion spring 13 which is capable of elastically supporting the corner portion 20 is coupled to the inner center thereof.
그리고, 이 스프링핀(11a)에는 코너부(20)가 탄성 지지되도록 내측단부는 상기 범퍼브래킷(11)의 내면에 지지됨과 더불어 외측단부는 코너브래킷(21)의 지지부(21a)에 지지된 비틀림스프링(13)이 결합되어 있다.The inner end of the bumper bracket 11 is supported by the spring pin 11a so that the corner 20 is elastically supported, and the outer end thereof is a torsion supported by the support 21a of the corner bracket 21. The spring 13 is coupled.
한편, 상기 코너브래킷(21)에는 코너부(20)에 외력이 작용될 때 완충작용이 이루어지도록 힌지부(12)에서 내측으로 연장돌출되어 상기 비틀림스프링(13)의 외측단부와 접촉된 지지부(21a)가 형성되어 있다.On the other hand, the corner bracket 21 protrudes inwardly from the hinge portion 12 so that a buffering action is made when an external force is applied to the corner portion 20, and a support portion which contacts the outer end of the torsion spring 13 ( 21a) is formed.
이하 본 발명의 작용에 대하여 상세히 설명하면 다음과 같다.Hereinafter will be described in detail with respect to the operation of the present invention.
상기한 바와 같은 본 발명에 따른 화물자동차 범퍼의 코너부결합구조에 의하면, 화물자동차 운행 중 운전자의 부주의 또는 실수로 접촉사고가 발생되어 본 발명의 코너부(20)에 외력이 작용되면, 상기 코너부(20)의 내측에 결합되어 있는 코너브래킷(21)이 힌지부(12)를 지점으로 회동되어 비틀림스프링(13)과 탄설된 지지부(21a)가 상기 비틀림스프링(13)을 압축하므로 코너부(20)가 외력에 의하여 파손되지 않고 완충작용을 하게된다.According to the corner portion coupling structure of the lorry bumper according to the present invention as described above, when an external force is applied to the corner portion 20 of the present invention by inadvertent or accidental accident of the driver during the operation of the lorry, the corner The corner bracket 21 coupled to the inside of the part 20 is rotated to the hinge portion 12 to the point, the torsion spring 13 and the coalesced support portion 21a compresses the torsion spring 13 so that the corner portion (20) is not broken by the external force is to act as a buffer.
그리고, 외부의 작용력에 의하여 회동된 코너부(20)는 외력이 상실되면, 탄성 변형된 비틀림스프링(13)의 복원력에 의하여 코너브래킷(21)이 회동되므로 외력이 작용되기 이전의 상태로 복귀된다.In addition, when the external force is lost, the corner portion 20 rotated by the external action force is returned to the state before the external force is applied because the corner bracket 21 is rotated by the restoring force of the elastically deformed torsion spring 13. .
이상과 같은 본 발명에 따른 화물자동차 범퍼의 코너부결합구조에 의하면, 화물자동차의 코너부는 운행 중 미소한 접촉사고로 인하여 외력이 작용되면, 힌지부를 지점으로 회동되며 완충되어 외력을 흡수하므로 손상 또는 파손이 방지된다.According to the corner portion coupling structure of the freighter bumper according to the present invention as described above, when the external force is applied due to a slight contact accident during operation, the hinge portion is rotated to a point and absorbed by absorbing the external force damage or damage Breakage is prevented.
그러므로, 상기 코너부의 손상이 방지되므로 교환으로 인한 경제적 손실이 절감되는 매우 유용한 것이다.Therefore, it is very useful that the economic loss due to exchange is reduced since the damage of the corner part is prevented.
