Shock-absorbing cushioning guard

Abstract

The problem was that there were many accidents involving rollovers and vehicles jumping onto the main road, resulting in numerous casualties. To improve the root cause of collision damage, we will provide impact-absorbing buffer guards. [Solution] This technology aims to prevent the escalation of accidents caused by the rebound characteristics of vehicle behavior. It is based on a tension spring, cylinder, and piston, which absorb and cushion by responding to compressed stress and stopping without reversing, and is a device that combines various parts that utilize different characteristics to complement its features. The most important element is the rebound characteristic during a collision, and by adding an effect that interferes with the destructive force of the collision and directs it to the stress area, the technology aims to prevent the escalation of accidents such as rollovers or unexpected movements that cause the vehicle to be thrown around and become involved in an accident. This technology includes the generalization of the device.

Description

Technical Field

[0001] The present invention relates to an impact-absorbing buffer guard installed at a road bifurcation zone, and relates to a technology of a device incorporating various mechanisms in order to reduce the human damage of casualties caused by a vehicle collision.

Background Art

[0002] Collision accidents of vehicles at the bifurcation points of roads existing in large numbers throughout the country, such as highways and national roads, frequently occur, and casualties and destructive damage to vehicles are undeniable. Upon verification, it was found that the vehicle bounces back during a collision. Depending on the collision surface, it often develops into a rollover or multiple accident, and is the number of accidents following the traffic jam rear-end collision accidents on general roads and highways. This is a technology of a device devised to reduce the number of casualties by reducing the damage by installing an impact-absorbing buffer guard having a function of absorbing and buffering the impact for modifying this bouncing-back characteristic.

[0003] As guards installed in the current bifurcation zones, there are facilities that have cushioning properties by putting water in a cylindrical container about the size of a resin drum can, and a form in which sandbag-type bags are stacked. And many of the general guardrails used on the side are bent into a U-shape. The impact and bouncing-back movement during a collision are fatal. This is a composite technology that overcomes these weaknesses, such as instantaneously (within a few seconds) softening the impact as absorption and buffering, greatly reducing the bouncing-back repulsion, and modifying the movement characteristics.

[0004] The combination is a technology based on three elements: a rubber-based rubber on the front, the elasticity of a piston-type coil spring, and a bouncing-back prevention stopper devised by a cylinder.

[0005] Also, because a collision is an inevitable S consideration, the current technology includes structures and mechanisms that simplify the repair and restoration from damage to devices and equipment, and because the repair is simple, it is considered to contribute to traffic itself and processing work.

Summary of the Invention

Problems to be Solved by the Invention

[0006] With current shock absorption systems, rebound characteristics often prove fatal, and control based on collision angle and location is unreliable. This is because the thinking is based solely on the primary element of absorbing and cushioning the impact. In other words, it relies on the idea that the shock absorption is solely the fault of the shock absorption equipment and the vehicle itself, resulting in the absorption performance of the corresponding equipment being almost nonexistent, and there is no consideration of absorption and cushioning. The rebound motion of the vehicle during a collision is violent, and the direction of the rebound is unpredictable, leading to rollovers near the point of impact, and unexpected behavior can cause vehicles to veer onto the main road and cause multi-vehicle accidents. The high number of accidents involving surrounding areas, rather than the number of deaths and injuries from direct collisions, has been a challenge in traffic safety measures. Means of solving the problem

[0007] The invention of claim 1, which solves this problem, is a technique of a combined mechanism that integrates the common-sense pressure theory of pistons and cylinders with multiple auxiliary devices to be added to the structure. It is a meaningful idea that can be called a new technology, and it is an idea that fundamentally solves the problem of fatalities in traffic accidents. Based on the results of experiments, it is a generalizable means that can be established as a new technology that can contribute to solving many problems.

[0008] The invention of claim 1 is a mechanism that merely combines some common-sense techniques, but it is a groundbreaking technology that produces results far exceeding the capabilities of what actually exists.

[0009] The invention of claim 1 is a means of technological fusion that integrates the characteristics of each part of the device, which are existing technologies, to absorb impact. These characteristics include a coil spring as a tensile force for elastic pressure distribution of a direct impact from the front, a cylinder and piston that guide the linear transfer of impact force, the installation of a hook to prevent reverse movement, and a discharge passage for impact air pressure. However, as a synergistic by-product, a characteristic of being drawn towards the center is obtained. A change in the forward attitude of the colliding vehicle, which can be called inertial induction of the collision vehicle due to inertial stability, has been confirmed. This characteristic makes it possible to increase the impact absorption and cushioning capacity.

[0010] The invention of claim 1 is easy to manufacture, and there are no issues with the manufacturing time. The cylinder and piston are different from those of an internal combustion engine, and precision in friction is not required.

[0011] The invention of claim 1 is based on the unique characteristics of the cylinder piston shape, which is the fundamental part of the technology. It provides cushioning and absorption through a combination of a coil spring for reverse control and a reverse prevention device. The only structural element of the technology is the movable hook, which acts as a stopper. However, due to its simple structure, it is not difficult to manufacture, and the device configuration is also simple.

[0012] The overall elements of the invention of claim 1 include a pressure reduction and discharge channel for internal air pressure to release impact pressure, and a concrete stabilizing base with a simple installation shape that improves overall performance. There are considerations for the stability of each part, such as a guidance assist mechanism for the direction of impact pressure and a cover to prevent deterioration of the equipment, and the combined use of these elements can be considered the technology itself.

[0013] The front cushioning rubber can be manufactured by re-vulcanizing and compression-molding discarded tires, and it performs adequately.

[0014] As an invention of claim 2, the structural and component characteristics of the overall invention of claim 1 are discussed separately. The mechanism for stopping the movement of the cylinder and piston should be considered as a separate technical aspect. This is a technique that uses an unusual component—a stopper—equipped with a stopper, which is a fundamental element of an internal combustion engine. Furthermore, considering the possibility that this unusual component may lead to ideas from inventors in various fields in the future, this unique piston structure should be considered a technical aspect.

[0015] The anti-reverse movable stopper attached to the cylinder and piston, which are the basic components, is movable by a repulsive coil spring, but it has a structure that allows it to be stored simply by pulling forward a metal plate with a freely movable opening in the intermediate layer, taking into consideration maintenance and resetting after operation. Effect of the invention

[0016] This invention provides a mechanism that allows the colliding vehicle to "stick" to the vehicle, drastically reducing the degree of impact, significantly decreasing phenomena such as rebound and bounce characteristics, preventing most rollovers and sudden movements, reducing complex accidents and collisions, and mitigating personal injury and property damage.

[0017] This invention can reduce the scattering of parts and damaged materials from devices and vehicles during collisions, which is expected to alleviate the burden of handling traffic accidents.

[0018] With this invention, the restoration and repair of the device can be completed in a short time due to the simple recovery function and structure, which is expected to significantly reduce costs and on-site work. [Modes for carrying out the invention]

[0019] Figure 1 shows the mechanism of Claim 1, which is the basic structure of the entire shock-absorbing buffer guard device of the invention. It is a structural cross-sectional view, and the dimensions, including the main body of the mechanism and the concrete fixing part for installation on general roads and intersections, are 600-1200 mm in width. For highway junctions, it is 1200-3000 mm, the height is about 900-1800 mm, and the total length is 600-3000 mm, etc., which will be adjusted on site. The arbitrary dimensions, which are assumed to cover a range from light vehicles to large vehicles, will be changed depending on the site conditions. Furthermore, the cylinder-piston structure, which is the innovative mechanism of the main body, will need to be enlarged by increasing the number of stoppers, etc., and it is essential to produce and stock multiple types.

[0020] Furthermore, in order to bring out the best characteristics, it is essential to use multiple basic mechanisms of the installation device, taking into account the road's shape and width. This includes selecting the size of the mechanism itself, considering combinations, and setting connections such as diagonal positions on the left and right sides of the front. The angle should be determined after considering the road width and curve shape at the site, and the device should be installed appropriately, including at T-junctions and on sharp curves.

[0021] Claim 2 has a cylindrical cylinder structure, but square, elliptical, etc. are adopted after verifying the strength and resilience characteristics of the metal. Regarding the thickness, commercially available steel materials such as 4.3 mm and 6.8 mm can be applied, but it is arbitrary. The material should be stainless steel 18-10 or higher with a hardness of about 5 for parts other than the spring.

[0022] Also, the basic tension-fixed spring can be made of commercially available steel materials within a possible range, but considering the acceleration pressure of the collision vehicle, the tensile strength is assumed to be 2 to 6.5 tons. However, if a large vehicle collides at a speed of 60 km / h, there is generally an impact of about 60 tons. The theory of this device is for buffering and not for confrontation with numerical values to prevent breakage, which is different from the essence of buffering and the strength to prevent breakage.

[0023] Furthermore, the exterior installed on this device is a protective exterior to adapt to the environment and prevent corrosion and deterioration of the equipment. It is desired to utilize it by arranging appealing coatings, characters, etc. on the surface.

[0024] Claim 3, while being auxiliary, is a crucial part of the technology that combines a mechanism that can be said to be an epoch-making boost by verifying the characteristics of guiding the front to the center of the piston while obtaining contact buffering in the intrusion direction of the collision object.

Industrial Applicability

[0025] The use of the invented impact-absorbing buffer guard is a place with secondary importance as a traffic accident scene. There was no perfect improvement measure, such as the protective collision object becoming a weapon and leading to a fatal accident. It is considered to be significant for human life in the future and to contribute to the future theoretical development or serve as a stepping stone. It is thought that it may be the origin of the ideas of future scientists who see this device. We hope that with more advanced skills, human life will be cherished, and it will be a technology that goes far beyond the direct use in industry.

[0026] Of course, for the use of this device, the existence of manufacturers is indispensable. Therefore, the profit from producing products related to human life that can be manufactured even in small town factories is not a commercial profit but a profound one.

[0027] A structural part used in the device. The rubber at the front utilizes waste tires. The concrete for fixing at the rear has low-density soft fracture characteristics. Since waste concrete, light and heavy blocks are optimal materials, in that sense, there is a significance in utilizing the negative parts of the industry.

[0028] Generally speaking, reducing the post-accident handling work is considered to be a significance in contributing to society.
