Abstract

Dynamic bumper protector, characterized by having some elastic springs of absorption, which previously calculated, are responsible for absorbing the forces arising in the collision of a vehicle. Once the force for which they have been calculated has been absorbed, and before any type of deformation in the vehicle is generated, it has detonation and explosion equipment, which is automatically activated, frontally counteracting the forces originating in the collision, with the forces that originate with the explosion, while reestablishing the elastic springs to their initial position, decompressing the system, so that it can absorb again what remains of the impact.

Description

DESCRIPTION

Dynamic bumper protector

Object of the invention

The present invention, as expressed in the statement of this specification, refers to a device, to counteract the forces arising in a vehicle collision. Which has been conceived and designed in order to obtain numerous and remarkable advantages, compared to other existing means of analogy purposes.

The device is designed to support in three distinct parts, the forces originated in a collision.

1 ° .- Absorb the forces generated in the collision

2 ° .- Counteract frontally the forces of the collision

3 ° .- Re-absorb the remaining forces of the collision

Background of the invention

Various devices are known that are used to withstand the forces originated in a collision with vehicles, among which include, conventional bumpers, already placed in vehicles, and that each time consist of better materials for the expansion of forces.

The seat belts, which tie the occupants in their seats, to prevent them from suffering blows when the collision originates.

And the airbags, whose well-known function is to insert an expanded bag between the occupants and the vehicle, just at the time of the collision.

The applicant is unaware of the existence of dynamic bumpers, such as the one described in this description.

Description of the invention

The device of the invention has a new structure in reference to conventional bumpers, which currently exist, on the basis of which three well differentiated effects are achieved and which guarantee a better response to the forces originating in a collision.

It consists of a bumper of expansion (2) that moves through the internal part of the device, and that is in the front of it, thanks to elastic springs (3) of great mechanical robustness, which are responsible for absorbing the blow during the first and third stages of the process.

The device also consists of an electronic system, which controls the detonators that activate the explosive charges (4), which have previously been calculated, and which are responsible for frontally counteracting the forces that originate in the collision, thanks to a system of striking of plungers (6) that move through the explosion chamber (5), hitting on the supports of the expansion bumper (2) and restoring it to its initial position (front part), so that in this way you can re-execute its function and absorb a second time, the forces remaining from the collision.

During the process and once the explosion is executed, which counteracts the forces of the collision, the system consists of a safety cover (9) (Mechanical Fuse) well calculated, which jumps to ensure that it does not suffer any type of damage and the once it releases the mechanism from all the accumulated pressure during the explosion, and in this way it guarantees again the response of the elastic springs of absorption.

The calculation of the dimensions and volumes of the system, the explosive charges, the forces of the elastic springs, the safety cover, etc. It will directly depend on the forces we burn to control in the collision, as well as on the part of the vehicle that we want to protect with the system, frontal, rear or lateral.

To complete the description that is being made, and in order to help a greater understanding of the characteristics of the invention, this description of a set of figures is accompanied, with which the innovations and advantages of the object device will be more easily understood. of the invention.

Description of a preferred embodiment

In view of the aforementioned figures, it can be observed how the equipment is made up of a body (1), an expansion bumper (2), two elastic absorption springs (3), a detonation and explosion equipment (4) , of an explosion chamber (5) and an embolism hitting system (6).

After making the relevant assemblies, this is sealed and sealed, ready for installation and mounting on the vehicle, which in this preferred embodiment, will be mounted behind the front bumper, at the height of the registration and will have the same dimensions as this .

The electrical connection will be made by means of a relay, which guarantees that the vehicle is started.

After starting the vehicle and in the event of a frontal collision, serious enough to cause the elastic springs (3) to perform all the shock absorption for which they have been calculated, the inductive detector detects it by detonating the load in the explosion chamber (5), which displaces the system of hitting of embols (6), instantly and before suffering any deformation of the vehicle by the collision, will return to reestablish its initial position to the expansion bumper (2), to the time that frontally counteracts the force that has been generated in the collision with the force that generates the explosion.

At the end of the explosion, the safety cover (9) jumps, releasing pressure from the whole mechanism, which again uses the expansion bumper (2) with the elastic springs (3) fully expanded, again guaranteeing the absorption of the impact, that it would have been reduced after the first two actions of the mechanism, guaranteeing in this way the reduction in a very high percentage of the consequences of the accident.

Claims (3)

1. Dynamic bumper protector, which is one of a series of elastic springs of absorption, which are responsible for absorbing the forces that originate in the collision of a vehicle. 2. Dynamic bumper protector, according to the first claim consists of a series of elastic springs of absorption, which once compressed all the elasticity for which they have been designed, activates a series of detonation and explosion equipment, which frontally counteract the forces that originate in the collision, with the forces generated by the system in the explosion, while reestablishing the expansion bumpers and elastic springs in their initial position. 3. Dynamic bumper protector, according to the second claim, consists of a series of detonation and explosion equipment, which reestablishes the expansion bumper and the elastic springs to their initial position, while simultaneously releasing the safety cover, which decompresses all the mechanism, so that in this way, the elastic springs can be activated again, guaranteeing another absorption of the impact again.
