Description

차량의 타이어 펑크시 안전제동장치Safety braking system for tire puncture of vehicle

본 발명은 차량의 타이어 펑크시 안전제동장치에 관한 것으로서, 상세하게는 타이어 펑크의 감지신호에 따라 각 바퀴 부위에 설치한 제동부재를 하방으로 인출되게 하여 지면에 접촉하게 함으로써 차량을 안정되게 제동시켜 사고를 방지하고자 하는 차량의 타이어 펑크시 안전제동장치에 관한 것이다.The present invention relates to a safety braking device for a tire puncture of a vehicle, and in detail, a braking member installed at each wheel part is pulled out in accordance with a detection signal of a tire puncture to bring the vehicle downward so that the vehicle is stably braked. The present invention relates to a safety brake device when a tire is punctured to prevent an accident.

일반적으로 차량을 운행함에 있어서 타이어의 펑크가 발생되면 차체가 일방으로 균형을 잃게 되어 고속주행시 차량의 전복 등 대형사고의 요인이 된다. 또한 차량이 전복되지 않더라도 여타 주행차선을 침범하게 되어 사고를 유발하게 되므로 그 위험성에 대하여는 새삼 강조할 필요가 없을 정도이다.In general, when a tire is punctured while driving a vehicle, the vehicle body is unbalanced in one direction, which causes a large accident such as a vehicle overturning at high speeds. In addition, even if the vehicle is not overturned, it will invade other driving lanes and cause an accident, so it is not necessary to emphasize the danger again.

종래에는 타이어의 펑크시 이를 해결하는 별 다른 장치의 보완이 없었으며, 자구책으로 타이어 내부에 공기가 주입된 튜브를 사용하지 않는 튜브리스(Tubeless) 타이어가 제공된 바 있다. 이는 타이어 내면에 이너라이너라고 불리우는 기밀성이 높은 고무층을 설치하고 비트부를 림플랜지에 압착하고 공기를 차단시킨 것으로 펑크시 급격한 공기 누설이 없으므로 안전성이 있으나 주행성이나 승차감이 다소 떨어지는 단점이 있다.In the prior art, there was no supplement of a different device that solves the puncture of the tire, and a tubeless tire that does not use a tube in which air is injected into the tire has been provided as a self-rescue. It installs a high airtight rubber layer called inner liner on the inner surface of the tire and compresses the bit on the rim flange and blocks the air.

그러나 일반적인 타이어에 있어서 주행중 펑크가 발생하면 단순히 속도를 급격히 감소시킨 후 차량을 정지시키는 것 이외에는 별다른 보완책이 없었다.However, if a puncture occurs while driving a general tire, there is no supplementary measure other than simply reducing the speed and then stopping the vehicle.

하지만 주행시 일측의 타이어에 펑크가 발생하면 차체가 급격히 일방으로 쏠리고 핸들을 빼앗기게 되므로 숙련된 운전자라도 사고발생의 위험이 매우 지대하다는 문제점이 있었다.However, when a puncture occurs on one side of the tire while driving, the vehicle body is steeply steered to one side and the handle is taken away.

본 발명은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로, 본 발명의 목적은 차량의 펑크시 자동적으로 펑크가 발생한 곳을 보완하여 차량의 균형을 유지하며 제동되도록 하는 차량의 타이어 펑크시 안전제동장치를 제공하는 데 있다.The present invention has been made in view of the conventional problems as described above, an object of the present invention is to compensate for the occurrence of the puncture automatically during the puncture of the vehicle safety braking during tire puncture of the vehicle to maintain the balance of the vehicle to brake To provide a device.

상기한 목적을 달성하기 위하여 본 발명은 차량의 각 바퀴부위에 설치하여 타이어펑크를 감지하는 감지센서(11); 상기 감지센서(11)의 감지치가 입력되는 ECU(12); 상기 ECU(12)의 신호를 받아 차체의 하방으로 인출되어 차량을 제동하도록 하는 제동부재(20)로 구성된 것을 특징으로 하는 차량의 타이어 펑크시 안전제동장치를 제공한다.In order to achieve the above object, the present invention is installed on each wheel of the vehicle detecting sensor for detecting a tire puncture (11); ECU 12 to which the detection value of the detection sensor 11 is input; Provides a safety braking device when the tire punctures the vehicle, characterized in that consisting of a braking member 20 for receiving the signal of the ECU 12 is drawn down to the vehicle body to brake the vehicle.

따라서 타이어펑크를 감지한 감지센서의 신호를 받아 자동으로 펑크발생된 부위의 제동부재가 하방으로 인출되어 펑크난 타이어의 높이를 대체하여 줌으로써 차량의 쏠림을 방지하고 제동되도록 한다.Therefore, the braking member of the punctured area is automatically drawn out by receiving a signal from a sensor that detects a tire puncture to replace the height of the flat tire, thereby preventing the vehicle from tipping and braking.

이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 구성도로서, (가)는 차체의 측면상태에서 구성을 간략히 나타낸 도면이고, (나)는 차체의 저면으로부터 구성상태를 나타낸 것이다. 도시한 바와 같이 본 발명은 차체의 전후륜 소정부위에 감지센서(11)를 설치하며, 이러한 감지센서(11)는 타이어 펑크시 소리에 반응하여 감지되는 것이 바람직하다.1 is a configuration diagram of the present invention, (a) is a view showing the configuration briefly in the side state of the vehicle body, (b) shows a configuration state from the bottom of the vehicle body. As shown in the present invention, the sensor 11 is installed on a predetermined portion of the front and rear wheels of the vehicle body, and the sensor 11 is preferably detected in response to a sound when the tire is punctured.

상기 감지센서는 ECU(12)와 연결되고, 이러한 ECU(12)로부터 액튜에이터(16) 및 내부에 가스가 수납된 피스톤부(18)가 연결되고, 이러한 액튜에이터(16) 및 피스톤부(18)가 차체프레임(30)의 하단, 각 바퀴부위에 설치된 제동부재(20)를 하방으로 구동하게 된다.The sensor is connected to the ECU 12, the actuator 16 and the piston unit 18 in which gas is stored therein are connected from the ECU 12, and the actuator 16 and the piston unit 18 The lower end of the body frame 30, the braking member 20 installed on each wheel portion is driven downward.

도면에서 부호 17은 피스톤부(18) 내의 가스를 점화하는 점화플러그이고, 부호 13은 상기 액튜에이터(16)에 압축공기를 공급하는 압축기, 14는 상기 압축기(13)를 구동하는 모터이며, 부호 15는 압축공기의 리턴을 방지하는 체크밸브다.In the figure, reference numeral 17 is an ignition plug for igniting gas in the piston 18, 13 is a compressor for supplying compressed air to the actuator 16, 14 is a motor for driving the compressor 13, and 15 is Is a check valve to prevent the return of compressed air.

한편 상기 제동부재(20)는 각 바퀴의 소정부위에 설치되는 바, 상부측이 차체프레임(30)에 고정된 액튜에이터(16)의 이동축(16a)과 연결되며, 상기 ECU(12)의 신호를 받아 작동되는 압축기(13)의 외부공기공급으로 액튜에이터(16)가 구동되어 하강하도록 구성된다.Meanwhile, the braking member 20 is installed at a predetermined portion of each wheel, and the upper side thereof is connected to the moving shaft 16a of the actuator 16 fixed to the body frame 30 and the signal of the ECU 12. Actuator 16 is driven to descend by the external air supply of the compressor (13) is operated to receive.

또한 상기 제동부재(20)의 중앙힌지(19) 일측 지지대(19a)는 차체프레임(30)에 고정된 브라켓(31)에 힌지연결되고, 타측의 지지대(19b)는 ECU(12)의 신호를 받아 점화되어 가스폭발로 구동되는 피스톤부(18)의 일단에 힌지 연결된다.In addition, one support 19a of the central hinge 19 of the braking member 20 is hinged to the bracket 31 fixed to the body frame 30, and the support 19b of the other side receives the signal of the ECU 12. The hinge is connected to one end of the piston unit 18 which is received and ignited and driven by a gas explosion.

이상과 같이 구성된 본 발명의 실시예에 대한 작동을 설명한다.The operation of the embodiment of the present invention configured as described above will be described.

차량의 일측 타이어에 펑크발생시 순간적으로 감지센서(11)에 감지되고, 이러한 감지신호를 ECU(12)에서 받아 점화플러그(17)를 작동시킨다. 이에 따라 피스톤부(18)에 내장된 압축가스(18a)가 폭발하면서 도 2에 도시한 바와 같이 피스톤(18b)을 밀어주게 되어 지지대(19b)를 밀게된다.When a puncture occurs in one tire of the vehicle, it is instantly sensed by the detection sensor 11, and receives the detection signal from the ECU 12 to operate the spark plug 17. Accordingly, as the compressed gas 18a embedded in the piston 18 explodes, the piston 18b is pushed as shown in FIG. 2 to push the support 19b.

이와 동시에 상기 ECU(12)의 신호는 모터(14)를 작동시켜 압축기(13)가 외부의 공기를 흡입하여 액튜에이터(16)로 보내게 되며, 따라서 액튜에이터(16)의 이동축(16a)이 하방으로 이동된다.At the same time, the signal of the ECU 12 operates the motor 14 so that the compressor 13 sucks external air and sends it to the actuator 16, so that the moving shaft 16a of the actuator 16 moves downward. Is moved to.

상기 피스톤(18b) 및 액튜에이터(16)의 작용으로 도 2의 점선위치에 있던 제동부재(20)가 실선의 위치로 이동되어 지면에 접촉하게 된다. 이때 상기 제동부재(20)의 밑면에는 마찰재가 형성되어 있음은 물론이며, 이에 따라 차량이 균형을 잃지 않고 안전하게 제동되게 된다.By the action of the piston 18b and the actuator 16, the braking member 20 in the dotted line position of FIG. 2 is moved to the position of the solid line to contact the ground. At this time, a friction material is formed on the bottom surface of the braking member 20, and thus the vehicle can be safely braked without losing balance.

참고적으로 이러한 본 발명의 작동상황을 도 3에 블록도로 나타내었다.For reference, the operation of the present invention is shown in FIG.

이상과 같이 본 발명은 차량의 펑크시 순간적으로 이를 감지한 감지센서의 신호를 받아 제동부재가 인출되어 지면에 접촉되므로 차량이 일방으로 쏠리지 않고 균형을 유지하게 됨과 동시에 제동의 효과를 실현하므로, 주행선 이탈로 인한 충돌사고를 최소화하고 차량은 물론 승차자의 안전을 보호하는 효과가 있다.As described above, the present invention realizes the effect of braking while maintaining the balance without being pulled to one side because the braking member is drawn out and comes into contact with the ground by receiving a signal of a sensing sensor which momentarily detects this during the puncture of the vehicle, There is an effect to minimize collision accidents caused by departure and to protect the safety of the vehicle as well as the rider.
