Abstract

Anti-ramping system of vehicles in frontal collision. # System in which in the front area of the vehicle it is divided into three zones, a central zone (3) with a triangular shape, which is non-deformable, and whose separation zone is based on the triangle between the passenger compartment (1) and the front part (2), and as a vertex of said area, the central point of the front part, leaving two other zones (4) and (5), also triangular, on both sides of the part front, and which are deformable zones, comprising structural reinforcements or reinforcing plates (6) and (7) that divide the central non-deformable zone (3) from the deformable zones (4) and (5); additionally it has another reinforcement plate (8) that goes from the free ends of the plates (6) and (7) at their junction points (11) and (10) respectively, with the lateral sides. It is achieved that before a frontal crash, instead of the absorption of energy resulting from the impact, deforming the passenger compartment, the deflection of the vehicle or vehicles involved is produced towards one side or the other.

Description

ANTI-EMPOWERING SYSTEM OF VEHICLES IN FRONT SHOCK

5 OBJECT OF THE INVENTION

It is the object of the present invention, as the title establishes, an anti-embedment system for vehicles in frontal collision, that is, it refers to a system for vehicles that in case of frontal collision avoids the embedding and frontal deformation of the

10 vehicles with the consequent advantage for the occupants of the vehicles.

The present invention characterizes the fact that thanks to the arrangement of structural reinforcement elements properly positioned both by the front and optionally at the rear of the vehicle, vehicles are diverted during a

15 frontal crash, avoiding the absorption of impact energy by deformation of the vehicle with the consequent danger to the occupants of the vehicle.

Therefore, the present invention is within the scope of the security means installed in the vehicles in order to protect the occupants thereof,

20 particularly during a frontal crash.

BACKGROUND OF THE INVENTION

In the state of the art the most common protective measures employed in the

25 vehicles are the seat belt, airbag and child protection. The vehicles are also equipped with additional means such as side impact protection bars, side airbags, or structural reinforcements in general.

In case of frontal impact, the safety means applied to the vehicles are, the

30 use of the seat belt that prevents the occupant from projected forward due to inertia. Dashboard or flywheel airbags are also used, which are deployed in the face of a relatively strong impact, generating a deformable air cushion that absorbs the occupant's energy from the forward projection, protecting it from bumps and damages.

They address the problem of a frontal collision seeking to mitigate its effects, instead of trying to avoid or reduce the energy that has to be absorbed in a frontal collision.

Therefore, it is the object of the present invention to develop a protection system for

5 vehicles that seek to reduce the energy of absorption in a frontal impact, so the consequences would be clearly minor, developing a system like the one to It is described below and is reflected in its essentiality in the first claim.

DESCRIPTION OF THE INVENTION

10 The object of the present invention is an anti-embedment system for vehicles in frontal collision, which basically consists of the provision of structural reinforcement elements duly placed and arranged in such a way that they deflect the vehicles before a frontal collision.

15 A vehicle, in general, can be considered divided into a part corresponding to the passenger compartment, where the occupants go, and a front or nose, where the engine of the vehicle goes. The object of the invention seeks to divide this front part into three different zones, a non-deformable central part, which has a triangle shape, which has as its

20 base the separation zone between the passenger compartment with the front part, and as a vertex the midpoint of the front front part of the vehicle, with two other areas being both sides of this triangular central part, which would have a triangular shape, and which is deformable and which allows the vehicle to be diverted to one side or the other before a frontal crash.

The system comprises at least two structural reinforcement elements arranged from each side end of the passenger compartment to the front of the vehicle at its midpoint.

Additionally, it comprises a third structural reinforcement element that joins the ends of the lateral structural reinforcements at its lateral end. This reinforcing element

30 additional structural serves as a means of strengthening the assembly, ensuring less energy absorption, and therefore deformation of the cabin.

The triangular geometry defined by the two lateral reinforcement elements and the third reinforcement element that corresponds to the triangle defined by the system

The anti-ramping system is applicable to both passenger cars and industrial vehicles, whose chassis is based on two parallel beams that run the entire vehicle from the rear to the front, in this situation it would be enough to join the beams in a central joint, in the exact middle of the front.

All of the above would also apply to the rear of the vehicles, which would also provide additional protection against subsequent scopes, which are also the result of accidents resulting in death.

10 Thanks to the characteristics of the anti-ramping system described, it is achieved that in the event of a frontal collision, either with another vehicle, or with a lamppost or tree, instead of the absorption of energy resulting from the impact, deforming the passenger compartment, the deviation occurs from the vehicle to one side or the other, a deviation that prevents deformation of the interior passenger compartment with the improvement of protection for its occupants, in addition to

15 serve as a means of absorbing impact energy.

PREFERRED REALIZATION OF THE INVENTION.

In view of the figures, a preferred embodiment of the proposed invention is described below.

15 In Figure 1 we can see a vehicle, which in general terms can be considered to comprise a first zone corresponding to the interior passenger compartment (1) where the occupants go, and a second zone or front zone (2) or also known as the vehicle's nose .

The invention proposes to divide the front zone into three zones, a central zone (3) with a triangular shape, which is non-deformable, and which has as its base the triangle the separation zone between the passenger compartment (1) and the front part (2) , and as the vertex of said area, the central point of the front, leaving two other zones (4) and (5), also triangular, to both

25 sides of the front, and that are deformable areas. These zones (4) and (5) have to be robust enough to support all the elements that are housed inside and that only in larger impacts are deformed to give way to the triangle and deflect the impact.

30 In order to divide the front part (2) into said zones (3), (4) AND (5), structural reinforcements are used, as shown in Figure 2, which at least consist of a plates (6 ) and (7). Where the plate (6) goes from the point (11) of the left side to the central point (9) of the front (2), while the plate (7) goes from the point (10) of the right side to the center point (9).

free ends of the plates (6) and (7) at their junction points (11) and (10) respectively, with the lateral sides.

The reinforcing elements as indicated may be reinforcing plates, which in

5 a possible embodiment may preferably be made of steel, with a about 40 cm high, which are embedded in the vehicle's chassis, and that the union between them, can be done by any means among the known, by some screws and nut, by welding, etc.

10 Figure 3 shows the evolutionary process that takes place in a frontal collision of two vehicles equipped with the anti-ramping system object of the invention, where in figure a) two vehicles (12) and (13) are shown approaching frontally, in figure b) the frontal impact is shown and in figure c) the deviation of the vehicles is shown

(12) and (13) one to each side, since a frontal collision is practically impossible

15 precise, and even if it were, the structural strength of the structural reinforcement elements (6) and (7) would force each vehicle to be diverted one to each side before deforming said plates.

Figure 4 shows a representation of the anti-recess system in its

20 ideal configuration, with a good oblique that causes the vehicle to deviate from a blow. The drawback is that the space that could be left for the engine is reduced, however, it is possible to advance the reinforcement plate (8) to the broken line.

25 In Figure 5 an alternative embodiment is shown in which the confluence of the lateral reinforcement elements is not made in the form of a vertex but has an additional plate (15), has a lower effectiveness but the motor gains space.

Figure 6 shows the construction where the reinforcement plate (8) has advanced,

30 has a greater space for the engine but loses effectiveness by reducing the obliqueness of the lateral reinforcement elements.

Figure 7 shows the construction characteristics of a possible embodiment of the lateral reinforcement elements (6) and (7), which each have

arranged at the ends of the plate (8) to be inserted in the oblong grooves (6.1) and (7.1) respectively.

Figure 8 shows the previous embodiment where it can be seen how the ends 5 of the plates (6) and (7) join with the ends of the plate (8) by passing the lugs

(8.1) Y (8.2) through the grooves (6.1) Y (7.1) And retaining them by means of nuts

(8 .3).

This configuration of the joint between the lateral reinforcement elements (6) Y (7) with the plate

10 (8) by means of oblong grooves (6.1) and (7.1) allows the first means to absorb the impact energy are the means of connection between the plates, causing the lugs (8.1) AND (8.2) to move through the oblong grooves (6.1) and (7.1), then later the plates themselves absorb the impact.

15 Figure 9 shows how on the connecting end of the plates (6) and (7) with each other, there are a series of hollow cylindrical projections (6.2) and (7.2) respectively, arranged alternately and complementaryly accommodates bias in each other in the spaces that remain between them, so that when fitted it is possible to pass a connecting rod (9.1) through the continuous perforation that has been defined, as shown in Figure 10.

20 Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is stated that, within its essentiality, it may be implemented in other embodiments that differ in detail from that indicated by way of example, and to which it will also achieve the protection sought, provided that

25 alter, change or modify its fundamental principle.
