Description

A kind of vehicle occupant leg defense of resistance to impact foot pad

Technical field

The utility model relates to motor vehicle blast protection engineering device technique fields, and in particular to a kind of vehicle occupant leg is anti- Surge guard foot pad.

Background technique

Armored vehicle design at the beginning of, anti-land mine ability install instead of motor vehicles consideration emphasis, with defence such as big gun Based on bullet, armor-piercing bullet etc..But the numerous battlefield data statistics terminated from World War II to cold war show antivehicle mine and improvised explosive Device IED (Improvised Explosive Device) has become the chief threat of motor vehicles.

Currently, the foot pad design in the world for panzer protection vehicle is fewer and fewer, domestic people grind for foot pad Study carefully and essentially consist in common anti-skidding, the effect of few dampings, let alone the function of explosion-proof protecting against shock.But in military combat In, panzer is weapon, and personnel are the switches for manipulating weapon, so the safety of the complete and personnel of vehicle is extremely important.Land mine It is usually hidden in underground, so, if landmine explosion, impact force is mainly transmitted from vehicle bottom, at this point for personnel's leg The injury in portion is very big, is such as not added to protect, will cause immeasurable consequence.In the prior art, started pair there are also people Protect the research of foot pad, but its protection effect for playing and bad.

Utility model content

The purpose of the utility model is to overcome the problems of panzer foot cushion structure protection effect difference in the prior art, thus A kind of vehicle occupant leg defense of resistance to impact foot cushion structure is provided, land mine can be effective against and improvised explosive explosion produces Raw shock wave protects the leg safety of personnel in armored vehicle.

To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions:

A kind of vehicle occupant leg defense of resistance to impact foot pad, including upper surface plate, energy absorbing component and lower plane plate, wherein institute Energy absorbing component is stated between upper surface plate and lower plane plate, the energy absorbing component includes two-layer pipe, the bimetallic tube knot Structure absorbs energy in impact process, after impact is completed, restores to the original state, thus reusable.

The two-layer pipe includes inner and outer tubes, is connected, is turned over by the tube wall of turnup between said inner tube and outer tube The tube wall of volume includes upper bending section, lower bending section and the intermediate tube for connecting upper bending part and lower bending section；In impact process In, the plastic deformation that the upper bending section and the lower bending section bend contracts between upper bending section and lower bending section Mouth deformation, to absorb energy.

Protecting foot pad further includes non-slip mat, and the non-slip mat is located on upper surface plate.

Staggered decorative pattern is provided in the non-slip mat.

Splice arrangement between the protection foot pad.

The beneficial effects of the utility model are: (1) protection foot pad provided by the utility model, has bimetallic tube by setting Structure and reusable energy absorbing component；The energy absorption capacity for effectively raising protection foot pad, greatly reduces the damage of occupant Wound, because reusable, also greatly reduces cost.

(2) protection foot pad provided by the utility model, by the way that two-layer pipe to be set as including inner tube, outer tube and company The tube wall of the turnup of inner and outer tubes is connect, the ability that protection foot pad absorbs energy is further improved.

(3) protection foot pad provided by the utility model is set in non-slip mat by the way that non-slip mat is arranged on the top of upper surface plate The decorative pattern for setting interlaced arrangement has achieved the effect that anti-skidding.

(4) structure of protection foot pad provided by the utility model, the protection foot pad is simple, and can splice between each other Arrangement connection, so as to use on a variety of military trucks, is not limited by a variety of models and different chassis shapes, is improved Applicable range.

Detailed description of the invention

It, below will be right in order to illustrate more clearly of specific embodiment of the present invention or technical solution in the prior art Specific embodiment or attached drawing needed to be used in the description of the prior art are briefly described, it should be apparent that, it is described below In attached drawing be that some embodiments of the utility model are not paying creativeness for those of ordinary skill in the art Under the premise of labour, it is also possible to obtain other drawings based on these drawings.

Description of symbols:

1- non-slip mat, the upper surface plate of 2-, 3- energy absorbing component, 4- lower plane plate, 5- two-layer pipe, 6- inner tube, 7- outer tube, The upper bending section 8-, bending section under 9-, 10- intermediate tube.

Specific embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in detail.

A kind of vehicle occupant leg defense of resistance to impact foot pad, including upper surface plate 2, energy absorbing component 3 and lower plane plate 4, Described in energy absorbing component 3 between upper surface plate 2 and lower plane plate 4, the energy absorbing component 3 include two-layer pipe 5, it is described Two-layer pipe 5 absorbs energy in impact process, after impact is completed, restores to the original state, thus reusable.

The two-layer pipe 5 includes inner tube 6 and outer tube 7, is connected between said inner tube 6 and outer tube 7 by the tube wall of turnup It connects, the tube wall of turnup includes upper bending section 8, lower bending section 9 and the intermediate tube 10 for connecting upper bending part and lower bending section；? In impact process, the plastic deformation that the upper bending section 8 and the lower bending section 9 bend, upper bending section 8 and lower bending section Necking deformation occurs between 9, to absorb energy.Energy absorbing component 3 uses thin-walled pressing-crack energy absorption device, in impact process, Energy absorbing component 3 mainly generates a constant power using the plastic deformation of metal tube, while making occupant by the deformation of energy absorbing component 3 Opposite body movement, to have the function that energy absorption.

Protecting foot pad further includes non-slip mat 1, and the non-slip mat 1 is located on upper surface plate 2.

It is provided with staggered decorative pattern in the non-slip mat 1, has been achieved the effect that anti-skidding.

Splice arrangement between the protection foot pad, the utility model has many advantages, such as that structure is simple, easy for installation.It can be more It is used on kind military truck, is not limited, can reasonably be spliced as needed by various different automobile types and different chassis shapes And it is arranged on armored vehicle.

When vehicle encounters the explosives such as land mine, vehicle floor will act on by the shock wave that explosion generates, pass through vehicle Bottom plate transfers force to lower plane plate 4, and the two-layer pipe in energy absorbing component 3 is by axial impact, 7 under tension of outer tube at this time It generates overturning to deform, in plastic history, the shape of deformed region is held essentially constant, so deformation force is relative constant.By Fig. 3, which can be seen that in two-layer pipe deformation process, absorbs energy mainly by three deformations: the upper deformation of bending section 8, necking deform And lower bending section 9 deforms.
