    专利说明:

    The present invention relates to the field of shock absorption, especially with regard to vehicles such as cars, and other mechanical systems causing shocks that can injure users or damage equipment.
    Known shock-absorbing devices are substantially complex systems having mechanical parts whose manufacture is tedious, consumes energy, and the manufacture or use is not very environmentally friendly.
    In the automotive field, bodywork or bumper elements associated with the vehicle side members have been proposed, making it possible to absorb shocks. The bumpers have an absolute programmed deformation zone around 55 to 60 km / h, determined by EuroNCaP type tests. Beyond 60 km / h, the risks for the passengers of the vehicle become significantly important.
    Unfortunately, studies show that 97% of speed-related automobile accident deaths are between 47 and 74 km / h, therefore leaving a range beyond 60 km / h with significant and frequent risks.
    [0005] A first objective of the invention is to provide a simple, efficient and environmentally friendly shock-absorbing device compared to the systems of the prior art.
    [0006] A second objective of the invention is to provide a device making it possible to absorb shocks in vehicles above 60 km / h while significantly reducing the risks for users.
    To do this is proposed a shock absorber device comprisinga shock receiving section forming a piston head,a piston arm associated with the piston head,a piston body associated with the piston head and the piston arm, the body comprising a fluid which is preferably substantially slightly compressible or non-compressible.
    According to a first aspect, the piston body comprising at least one elbow or curved part, and is arranged along at least one proximal section in a proximal direction and a distal section in a distal direction.
    [0009] Further, the piston body includes at least one pressure sensitive shutter on the distal section.
    In particular, above a pressure threshold of the piston, the shutter is at least partially destroyed so that the fluid escapes through the distal section.
    Advantageously, the damping device has a simple constitution with elements that are easy to manufacture. Further, the use of a piston and a substantially incompressible medium can be calibrated to have significant damping efficiency, and is substantially environmentally friendly.
    [0012] In addition, the device makes it possible to absorb shocks from vehicles above 60 km / h, thus significantly limiting bodily injury from speed-related accidents.
    According to other aspects taken in isolation, or combined according to any technically feasible combinations:said obturator is disposed at the distal end of the distal section; and orthe piston body includes a filling structure; and orone or the filling structure is disposed at the proximal section; and orthe proximal section is substantially horizontal and the distal section substantially oblique downward; and orthe proximal section is substantially horizontal and the distal section substantially vertical downward; and orthe proximal section is substantially horizontal and the distal section substantially vertical upwards; and orthe proximal section is substantially horizontal and the distal section is substantially horizontal rearwardly, and preferably not aligned with the proximal section.
    The invention further relates to a shock absorber system comprising at least two shock absorber devices according to one of the preceding claims, in series or in parallel.
    Another object of the invention relates to a vehicle comprising at least one shock absorber device according to the invention or at least one shock absorber system according to the invention, facing the body.
    The invention further relates to a firearm comprising at least one shock absorber device according to the invention or at least one shock absorber system according to the invention, facing the hammer.
    [0017] The invention also relates to a method for absorbing a shock characterized by the placement, at a shock receiving zone, of a shock receiving section of at least one shock-receiving device. shock absorber according to the invention or a shock absorber system according to the invention.
    The invention will be further detailed by the description of non-limiting embodiments, and on the basis of the appended figures illustrating variants of the invention, in which:Figure 1 is a side view diagram of a device according to a preferred embodiment of the invention;FIG. 2 is a diagram in side view of a vehicle comprising the device of FIG. 1;FIG. 3 is a diagram in top view of a vehicle comprising two devices of FIG. 1;FIG. 4 is a diagram of another embodiment of the device according to the invention;FIG. 5 is a diagram illustrating two devices of FIG. 4 in series; andFIG. 6 is a diagram of an embodiment applied to firearms and other apparatus.
    The invention relates to the damping of shocks in several areas where shocks can cause bodily injury or material damage.
    The invention is particularly applicable to the damping of impacts from vehicles such as motor cars, trains, aircraft, motorcycles, etc.
    To this end, the invention relates to a shock absorber device 1.
    The device 1 comprises a shock receiving section 2 forming the piston head. This is in particular the end to be pushed to actuate a piston.
    The device 1 further comprises a piston arm 3 associated with the piston head 2. In particular, the arm 3 can be integral with the head 2, and transmits the force applied to the head 2 to the rest of the piston.
    The device 1 further comprises a piston body 4 associated with the piston head 2 and the piston arm 3. The piston body 4 closes a chamber 5 preferably hermetic. The body 4 comprises a fluid 6 which is preferably substantially slightly compressible or non-compressible. The compressibility of the fluid 6 makes it possible to limit the losses of force between the upstream side of the piston and the downstream side of the piston.
    According to a first aspect, the piston body 4 comprises at least one elbow or curved section 7. The piston body 4 is arranged along at least one proximal section 4a in a proximal direction A and a distal section 4b in a distal direction B. Preferably, the distal section 4b is different from the proximal section 4a.
    In addition, the piston body 4 comprises at least one pressure sensitive valve 8.
    In particular, above a pressure threshold of the piston, the shutter 8 is at least partially destroyed so that the fluid 6 escapes through the distal section 4b. This allows the intensity of the shock to be shifted to the distal section of the device. More particularly, an action / reaction mechanism is applied by the piston to the fluid 6 so that the fluid 6 performs a proportional reaction in the distal direction B.
    Advantageously, the damping device 1 has a simple constitution with elements that are easy to manufacture. Further, the use of a piston and a substantially incompressible medium can be calibrated to have significant damping efficiency, and substantially environmentally friendly manufacture and use.
    [0029] In addition, the device 1 makes it possible to absorb a vehicle impact above 60 km / h, thus significantly limiting bodily injury from speed-related accidents.
    [0030] According to a variant, the obturator 8 is disposed at the distal end of the distal section B. Advantageously, this makes it possible to move the intensity of the shock even better towards the distal end of the device 1.
    According to a variant, the piston body 4 comprises a filling structure 9. This structure 9 is configured to fill the fluid and preferably close in a substantially hermetic manner. It can be any connection structure to fill the device. Advantageously, this makes it possible to reuse the device 1.
    [0032] According to a variant, the filling structure 9 is arranged at the level of the proximal section 4a. Advantageously, this configuration, the filling structure 9 is little subject to the pressures of the piston acting more in the distal section 4d.
    According to a variant, the proximal section 4a is substantially horizontal and the distal section 4b substantially oblique downward.
    This arrangement makes it possible to damp horizontal shocks, and the corresponding force is exerted downwards. This variant is advantageous for applications in land or marine vehicles.
    One can consider a substantially horizontal proximal section and a substantially vertical distal section downward or upward.
    In another variant, the device can comprise several distal sections 4b. Advantageously, this makes it possible to distribute the force over several outputs.
    One can also imagine distal fan sections, for example 5 to 10 outlets, which may be of different sizes in length and / or in thickness, for example increasing.
    According to a variant, the proximal section 4a is substantially horizontal and the distal section 4b substantially horizontal towards the rear and preferably not aligned with the proximal section 4a. In particular, this variant may further comprise an intermediate section 4c with several concavities, more particularly with double concavity, for example in an “S” shape.
    This variant is particularly suitable for firearms 10 having a barrel 11 and a hammer 12 or a similar structure, or similar equipment such as war tanks.
    Indeed, the impact of the hammer 12 on the ammunition generates propulsion of the hammer 12 backwards which can damage the weapon 10 or injure a user 13. In addition, this moves the weapon 10 and limits the shot accuracy.
    Thus the device 1 according to this variant makes it possible to absorb the shock of the hammer 12 and to limit the associated inconvenience.
    The invention further relates to a shock absorber system comprising at least two shock absorber devices 1 as described above.
    The devices 1 can be in series, that is to say placed one after the other.
    In particular, the devices 1 in series can be connected by the fluid, that is to say have fluids in communication longitudinally; and / or connected by the pistons 3, ie the front piston arm extends into the rear device or actuates a rear piston. This makes it possible to have sequential depreciation.
    The devices 1 can be in parallel, that is to say placed next to each other. In particular, the devices in parallel can be connected by the fluid, that is to say have fluids in communication laterally; and / or connected by the shock receiving structure or the lateral parts of the heads and / or arms of the pistons. This makes it possible to distribute the shock over several devices, in particular over several heads 2 and / or arms 3 of the piston.
    The invention further relates to a vehicle 14 comprising one or more devices as described above. The vehicle can be land, marine, air, space or a train.
    For example, car side members may have the shape of a piston, the head 2 of which is associated with the rear of the bumper 15.
    Another structure can also be considered behind a bumper or another bodywork element or between the exterior and the passenger compartment.
    Another object of the invention relates to a firearm 10, or another apparatus, barrel 11 and hammer 12 comprising a device 1 as described above.
    The invention also relates to a method for absorbing a shock characterized by the establishment, at the level of a shock receiving zone, such as a bumper 15, of a shock receiving section. shock 2 of at least one shock absorber device 1 as described above.
    The invention also applies to other mechanical systems generating shocks that can injure users or equipment.
