Description

VEHICLE COLLISION ABSORPTION AND PROTECTION STRUCTURE

Technical Field

The invention relates to a vehicle collision absorption and protection structure for vehicles in the passenger car category, which is mounted on the front and rear parts of the vehicles and prevents collision effects during front or rear collisions with trailers belonging to towing vehicles while in motion, using collisionabsorbing panels and collision fillers, and preventing the cabin section of passenger vehicles from going under the trailers with a spring-loaded telescopic arm, thus increasing the safety of passenger vehicle drivers and passengers.

Prior Art

The use of intelligent systems in passenger vehicles plays a significant role in reducing traffic accidents today. However, it is also observed that these technologies can sometimes be inadequate. For example, driver negligence or sudden changes in road conditions can still lead to accidents. While smart vehicles can reduce drivers' reaction times in some cases or anticipate critical situations in advance, it may not be possible to foresee and prevent every possible scenario.

There are various reasons for accidents on highways. In addition to human factors such as driver negligence, fatigue, or driving under the influence of alcohol, vehicle defects also play a significant role. The inadequacy of vehicle designs contributes significantly to highway accidents. Especially automobile manufacturers continuously develop new technologies and safety measures to make vehicles safer. However, there may still be deficiencies or design flaws in passenger vehicles whose basic design has remained unchanged for many years.

For instance, inadequate systems ensuring vehicle stability during collisions or issues related to the durability of the vehicle body can lead to serious consequences in highway accidents. Problems like insufficient braking systems or steering response can make vehicle control difficult and lead to accidents.

Additionally, accidents like going under trailer trucks can be attributed to the inadequacy of vehicle design. Especially due to their height, trailer trucks may be difficult for drivers to perceive, and this can lead to passenger vehicles going under trailer trucks, especially when making sharp turns or not leaving enough distance behind the vehicle.

Many manufacturers and independent inventors are working on improvements related to this issue. For instance, in Turkish Patent Document TR2019/12434 titled "Dynamic Impact Absorber," the document addresses the issue by mounting a metal barrier dynamic impact absorber on the rear side of trailers to prevent the impacting vehicle from going under the trailer in rear-end collisions. However, the installation of this absorber on trailer trucks was considered, taking into account the differences in trailers, the number of competent vehicles in traffic, and the passenger-carrying capacity being higher in passenger vehicles than in trailer- classified towing vehicles, it is debatable whether this variability in trailers would provide a safety benefit. Additionally, when considering multi-purpose construction vehicles, the mechanism might create compatibility issues with most trailer types, hence the invention is seen as not providing sufficient benefit.

Another reference is made in Turkish Patent Document TR 2019/14377 titled "Protective Devices Against Fatal Traffic Accidents," where an Elastic-Flexible device for absorbing impact is applied to a vehicle approaching a stopped or slower-moving vehicle from behind at a high speed, aiming to prevent fatal traffic accidents. However, unlike the first file mentioned in the previous technology, this is decided to be applied not in passenger vehicles with high passenger capacity but in the class of towing vehicles carrying cargo and connected trailers. Based on the examples mentioned above, in order to prevent such accidents, especially passenger vehicle manufacturers should develop design features that provide better durability and protection. Therefore, the inventor, noticing the lack in this regard, has decided to publish their invention titled "Vehicle Collision Absorption and Protection Structure."

Purpose of the Invention

The main purpose of the invention is to ensure the maximum safety of the driver and passengers in the vehicle during accidents.

Another aim of the invention is to increase vehicle resistance, which is another important detail of accident prevention systems prioritizing safety, with the goal of minimizing property damage.

The invention (1) is related to a vehicle collision absorption and protection structure that is mounted on the front and rear parts of vehicles (A) in the passenger car category, and it mitigates the collision impact during front or rear collisions with trailers (B) belonging to towing vehicles by using an absorbing panel (5) and a collision filler (6). It also prevents the cabin section of passenger vehicles (A) from going under trailers (B) by means of a spring-loaded telescopic arm (7), thereby enhancing the safety of passenger vehicle (A) drivers and passengers.

The invention (1) comprises:

At least one socket (2) that creates a pre-defined empty space underneath the mentioned vehicles (A) according to their brands and models for mounting the invention (1) on passenger vehicles (A), At least one collision detection sensor (3) placed on the front and rear parts of the mentioned vehicle (A), which adjusts the thrust speed of a piston (4) based on the collision intensity by detecting the distance to other passenger vehicles (A) or trailers (B) with trucks having a front or rear traveling distance,

A closed position within the socket (2), a piston (4) that converts pneumatic power into motion power horizontally through pneumatic cylinders based on the distance measurement of other passenger vehicles (A) or trailers (B) received from the mentioned collision detection sensor (3) during collision, and thus, prevents the loading of force onto the vehicle chassis during collision by acting as a protective solid elbow panel during the collision, and provides support panel functions between vehicles through at least one absorbing panel (5),

At least one collision filler (6) that is mechanically and structurally joined to the mentioned absorbing panel (5) from the front and acts as a shock absorber during the first impact of collision, and simultaneously activates the spring mechanism of the spring-loaded telescopic arm (7) immediately after the mentioned piston's (4) advancement during collision,

At least one spring-loaded telescopic arm (7) located inside the mentioned collision filler (6) that moves telescopically in a perpendicular direction to the horizontal plane during collision via internal springs, preventing the cabin section of the passenger vehicle (A) from colliding with another passenger vehicle (A) or trailer (B) during collision, thus ensuring cabin safety.
