Abstract

The present invention relates to a speed bump comprising a dilatant fluid. According to the present invention, the dilatant fluid can be additionally supplied at any time by allowing the inflatable fluid to be injected into the inside of the speed bump. Also, for fixing the speed bump, holes are formed at both ends of the speed bump so that screws can be fixed, so the speed bump can be installed easily. Unlike an existing speed bump, only a driver of a speeding vehicle can feel the vibration as the vehicle passes over the speed bump containing the dilatant fluid of the present invention, so that the driver recognizes that he or she has been speeding. The speed bump comprising a dilatant fluid comprises: a lower end unit; an upper end unit; and a built in unit.

Description

팽창성유체가 포함된 과속방지턱 {Speed bump filled with dilatant fluid}{Speed bump filled with dilatant fluid}

본 발명은 팽창성유체가 포함되어 기존의 딱딱한 표면의 고체로 이루어진 과속방지턱에 의한 차량 손상을 방지하는 차량용 과속방지턱에 관한 것이다.The present invention relates to a speed bump for a vehicle that contains an inflatable fluid to prevent damage to the vehicle by a speed bump made of an existing hard surface solid.

과속방지턱은 차량의 주행 속도를 강제로 낮추는 목적이 있으며 도로에 설치되어있다. 대한민국 국토교통부가 정한 규격에 따르면 과속방지턱의 규격은 폭 3.6m, 높이 10cm이다. The speed bump has the purpose of forcibly lowering the driving speed of the vehicle and is installed on the road. According to the standards set by the Ministry of Land, Infrastructure and Transport of the Republic of Korea, the speed bump is 3.6 m wide and 10 cm high.

자비로 만든 과속방지턱은 규격보다 더 높게 만들어지는 경우가 많다. 지나치게 높은 과속방지턱은 차량 하부가 긁히거나 천천히 달리더라도 평지와의 높이차로 인해 차체에 충격이 가해진다.Self-made speed bumps are often built higher than standard. If the speed bump is too high, the lower part of the vehicle is scratched or the vehicle is impacted due to the difference in height from the flat ground even if the vehicle is running slowly.

평평한 도로를 주행하도록 설계된 차량에게 있어 과속방지턱은 차량에 상당한 충격을 가하게 된다. 과속 방지턱을 지나가면서 차량이 큰 충격을 받기 때문이 쇼크업소버나 서스펜션 등에 손상을 준다.For vehicles designed to drive on flat roads, speed bumps have a significant impact on the vehicle. The shock absorber or suspension is damaged because the vehicle receives a large impact while passing over a speed bump.

종래의 과속방지턱은 노면의 재질이나 플라스토머 고무로 이루어져있으며 차량이 저속도로 지나가더라도 자동차는 아치형태의 과속 방지턱으로 인해 강한 진동이나 약한 충격을 받는 일이 잦다. 이는 차체의 손상을 유발할 뿐 아니라 탑승자에게 불편함을 안겨주기도 한다.Conventional speed bumps are made of a road surface material or plastomer rubber, and even when a vehicle passes at a low speed, the vehicle often receives strong vibrations or weak shocks due to the arch-shaped speed bump. This not only causes damage to the vehicle body, but also causes inconvenience to occupants.

위와 같은 문제점을 해결하기 위해, 본 발명은 팽창성유체의 점탄성 특성을 일정 속도 이하로 움직이는 물체에 관해선 팽창성유체가 점성이 낮은 유체로서 거동하기 때문에 과속방지턱에 의한 차체 손상을 방지할 수 있으며, 일정 속도 이상으로 움직이는 물체에 관해선 고체처럼 거동하여 저속으로 과속방지턱을 지날 때 차체에 손상을 주지 않는 과속방지턱을 제공한다.In order to solve the above problems, the present invention can prevent damage to the vehicle body due to speed bumps because the inflatable fluid behaves as a low-viscosity fluid with respect to an object moving the viscoelastic properties of the inflatable fluid at a speed below a certain speed. As for the above-mentioned moving object, a speed bump that behaves like a solid and does not damage the vehicle body when passing the speed bump at low speed is provided.

본 발명 팽창성유체가 포함되어 있는 과속방지턱 (Speed bump filled with dilatant fluid)은 기존 조립식 과속방지턱에 사용되는 재질인 ‘플라스토머’(Plastomer)를 하단 부분에 사용하며, 상단부는 고무판을 사용하여, 볼트와 너트 그리고 와셔를 이용하여 밀봉을 한다. 또 한, 고무판 상단에 주입구를 설치한다.The speed bump filled with dilatant fluid containing the inflatable fluid of the present invention uses 'Plastomer', a material used in existing prefabricated speed bumps, for the lower part, and the upper part uses a rubber plate, Seal with bolts, nuts and washers. Also, install the inlet on the top of the rubber plate.

상단 부분에 일정한 힘이 가해질 시, 팽창성유체의 특성을 활용해, 평상시에 유체 상태를 유지하며, 힘이 가해지면, 고체로 변하면서 기존 과속방지턱의 역할을 할 수 있다. 따라서 차량이 서행 할 시, 유체 상태의 과속방지턱을 넘어 갈 수 있으므로, 차량에 손상이 가해지지 않는다.When a certain force is applied to the upper part, it maintains a fluid state in normal times by utilizing the characteristics of an inflatable fluid, and when a force is applied, it turns into a solid and can act as an existing speed bump. Therefore, when the vehicle is traveling slowly, it can go over the speed bump in a fluid state, so there is no damage to the vehicle.

본 발명은 팽창성유체가 포함되어 있어 기존의 과속방지턱을 넘어갈시 약하지만 차체의 손상이 가해지는 것을 방지 할 수 있게 된다. The present invention contains an inflatable fluid, so it is weak when going over the existing speed bump, but it is possible to prevent damage to the vehicle body.

또한, 기존의 과속방지턱을 과속을 하지 않는 운전자도 과속방지턱을 부드럽게 넘어 갈 수 있다.In addition, a driver who does not speed over the existing speed bump can smoothly go over the speed bump.

또한, 과속방지턱을 넘어 가면서 운전자가 진동을 느낄 시 과속을 했다고 운전자가 인지할 수 있게 된다.In addition, when the driver senses a vibration while crossing a speed bump, the driver can recognize that he or she has been speeding.

FIG. 2 is a perspective view of a speed bump including an inflatable fluid according to an embodiment of FIG. 2 as viewed from below; FIG.

도시된 바와 같이 팽창성유체가 포함되어 있는 과속방지턱 (Speed bump filled with dilatant fluid)는 플라스토머 (Plastomer)로 제작된 하단부 (밑면) (10), 고무판으로 제작된 As shown in the figure, the speed bump filled with dilatant fluid includes the lower part (bottom) 10 made of plastomer and the rubber plate.

상단부 (20), 상단부 (20) 를 지면과 고정시켜줄 나사 (screw) (22), 방지턱 내부에 삽입된 팽창성유체The upper part 20, the screw 22 to fix the upper part 20 to the ground, and the inflatable fluid inserted into the sill

팽창성유체 (30), 그리고 팽창성유체를 주입하기 위한 주입구 (21)를 포함한다.It includes an inflatable fluid 30, and an inlet 21 for injecting the inflatable fluid.

하단부 (10)은 기존 조립식 과속방지턱 제작 과정에서 쓰이는 재질인 플라스토머 (Plastomer)를The lower part (10) is made of plastomer, a material used in the manufacturing process of existing prefabricated speed bumps.

이용해 지면과 고정할 수 있도록 해준다.This allows it to be fixed to the ground.

하단부 (10)과는 달리, 상단부 (20) 는 고무판으로 제작하여, 팽창성유체의 효과를 최대치로 끌어 Unlike the lower part 10, the upper part 20 is made of a rubber plate to maximize the effect of the inflatable fluid.

올릴 수 있도록 한다. to be able to raise

차량이 과속방지턱을 지나갈 때 과속방지턱 내의 팽창성유체가 유체적으로 거동하게 하기 위해, 팽창성유체에 힘을 가할 수 있는 재질을 상단부에 적용한다.. In order to make the inflatable fluid in the speed bump behave fluidly when the vehicle passes the speed bump, a material that can apply a force to the inflatable fluid is applied to the upper part.

즉, 상단부 (20)는 종래의 과속방지턱과는 달리 고무판으로 제작되었다는 점을 이용하여, 차량이 That is, by using the fact that the upper part 20 is made of a rubber plate unlike the conventional speed bump, the vehicle

낮은 속도에서 운전할 때는 유체 상태를 유지하며, 차체에 손상을 가하지 않을 뿐 더러, 운전자It remains fluid when driving at low speeds, does not damage the body, and

역시 이질감을 느끼지 않는다. 반면, 기존 과속방지턱은 차량이 서행할 시에도, 차량에 어느I also don't feel any ambivalence. On the other hand, the existing speed bumps prevent any damage to the vehicle even when the vehicle is moving slowly.

정도의 손상이 가해지며, 운전자 역시 과속방지턱을 넘어가면서 덜컹거리는 불편함을 느낀다.A degree of damage is inflicted, and the driver also feels uncomfortable when going over a speed bump.

이 뿐만 아니라, 팽창성유체 과속방지턱 (Speed bump filled with Non Newtonian fluid)는 차량이In addition to this, the speed bump filled with Non Newtonian fluid

일정 속도를 초과하여 운행하면, 유체에서 고체로 변환되며 기존 과속방지턱의 성질을 갖게된다.If it is driven over a certain speed, it is converted from a fluid to a solid and has the properties of an existing speed bump.

나사 (screw) (22)는 상단부 (20)를 하단부 (밑면) (10)과 지면을 동시에 고정시켜 줄 역할을 한다. The screw 22 serves to simultaneously fix the upper end 20 to the lower end (bottom) 10 and the ground.

방지턱 내부에 삽입된 팽창성유체 (30)는 옥수수 녹말, 전분, 콜라겐, 키토산 The intumescent fluid 30 inserted into the bump is cornstarch, starch, collagen, chitosan.
