Abstract

The invention discloses a push rod type anti-collision automobile, and belongs to the field of automobile safety technology. When the automobile is suffered from head-on collision, in order to extend the inertia energy of a carriage of the automobile and release distance and interval on space and time, the following technical measures are adopted: the automobile is mainly divided into a frame and the carriage; the carriage is horizontally and movably connected to the frame; a push rod power absorber is mounted between the frame and the carriage; the push rod power absorber is composed of long and short, or equally length single push rod or a plurality of push rods; when the automobile is suffered from head-on collision, the carriage can horizontally move forwards relative to the frame under the action of inertia, and squeeze the push rod power absorber forwards. As the loading capacity of the push rods of the push rod power absorber is smaller than the forward horizontal movement force, the push rods are sequentially curved and deformed by the carriage from the long to the short. When one push rod or the plurality of equal length push rods is/are curved, the carriage can consume a part of inertia energy. In this way, the impact strength to the carriage and the internal passengers can be reduced.

Description

Post rod type anti-collision automobile

Technical field

The invention belongs to a field in automotive safety technology.

Background technology

Automobile on road surface is more and more, and traffic accident is also more and more frequent.According to statistics, in vapour collision case, the chance rate that vehicle front bumps is the highest, and almost, in each vapour collision case, the rarest side's automobile is frontal collisions.Therefore, the emphasis of automobile collision preventing considers it is frontal collisions; During galloping, due to the effect of inertia of material, automobile and passenger thereof store huge inertia energy.Just in case at this moment automobile generation frontal impact, these energy abrupt releases, will produce huge impulsive force, and its consequence is hardly imaginable.Because during frontal crash of vehicles, speed of a motor vehicle moment reduces, and even replys quiescence.Passenger inside the vehicle, in this process, will bear huge impulsive force forward, will be therefore likely injured.In prior art, for when the automobile generation head-on crash, can relax extraneous impulsive force, all, in the front and back of the longeron of automobile chassis frame, crashproof girder steel and low speed energy-absorption box are installed.Wish that it is when clashing into generation, the distortion that can lead to metal carrys out apparatus with shock absorbing.Reduce the impulsive force that in car, each occupant bears, protect automobile and passenger as far as possible.But, due to the total distance in crashproof girder steel and the low speed energy-absorption box front and back altogether 20-30 centimetre of only having an appointment.Therefore, its geometry deformation size is very limited, and the space of distortion is very limited, also very limited to automobile and passenger's protection.Reason is very simple, and in the dispose procedure of inertia energy, under the prerequisite of same inertia energy, ranging coverage is longer, and the impulsive force of generation is less, otherwise anti-.From current motor traffic accidents injures and deaths situation, the deformation space of 20-30 centimetre is far from being enough, and the protective capability that it can form is very limited.In prior art, for mending this deficiency, invented safety air bag.But, on automobile, not on each seat, load onto safety air bag, moreover the expansion of safety air bag self also has certain danger.Although safety air bag quality is little, speed when moment launches is high, and this velocity of impact is not a peanut for human body.According to the statistics of some national highway safety management departments, safety air bag is in collision traffic accident in 100 passenger life of every redemption, also because of the inappropriate expansion of air bag and occupant's mal seating position and sitting posture, unfortunately cause 57 occupants to lose life.Above-mentioned these are all, after car accident occurs, in the accident of particularly clashing in vehicle front, always to have injured even one of the main causes of death of so much people.Visible, the effort of indented material is also not so good as people's will, and space still has greatly improved.While how to allow automobile generation frontal collisions, the inertia energy that the passenger in compartment has, can obtain discharging as far as possible slowly, to reduce impact dynamics that in compartment, occupant bears, reduce injures and deaths, is purposes of the present invention.

Summary of the invention

For making automobile when there is head-on crash, can extend the inertia energy in compartment, the release distance on time and space, reduces the impact dynamics that in compartment, personnel bear, and protects more preferably the full complement in compartment.The present invention has taked following technical measures: automobile primary will be divided into

vehicle frame

1 and 2 liang, compartment major part, and compartment 2 horizontal anomalous movements are connected on vehicle frame 1.Between vehicle frame 1 and compartment 2, push rod energy absorber 3 is housed.Push rod energy absorber 3 be by have long have short, with long, have wall scroll or many s' push rod to combine.The push rod of push rod energy absorber 3 is arranged between compartment 2 and vehicle frame 1, as shown in Figure 1.

Owing to being horizontal anomalous movement annexation between vehicle frame 1 and compartment 2, between vehicle frame 1 and compartment 2, push rod energy absorber 3 is housed simultaneously.So when the automobile generation head-on crash, compartment 2 under the effect of inertia, can occur with respect to vehicle frame 1 forward, i.e. parallel motion longitudinally, and produce the parallel motion power of this direction.This parallel motion power forward, can push push rod energy absorber 3 forward.Because push rod energy absorber 3 is less than this parallel motion power (impulsive force) forward with long wall scroll or the bearing capacity of many push rods, so push rod is successively bent and is out of shape by compartment 2 one by one from long to short.Every press-bending one or more is with long push rod, and compartment 2 all will consume a part of inertia energy.The inertia energy that so just can make compartment 2 have obtains progressively discharging slowly, has reduced the impact dynamics that compartment 2 and interior passenger thereof once born, and has effectively protected compartment 2 and interior passenger thereof.

In figure: vehicle frame 1, compartment 2, push rod energy absorber 3, square tube 4.

The specific embodiment

Vehicle frame 1 described in the application is connected and refers to horizontal anomalous movement between compartment 2: compartment 2, with respect between vehicle frame 1, can carry out horizontal shifting, the annexation vertically moving.The mode that can realize this annexation is a lot, for example, use radial type connection, sleeve type connection, the buckle-type of rocking arm to connect etc.This routine horizontal anomalous movement connects, and has selected sleeve type connection mode.It is by below compartment 2, and hard-wired four square tubes 4 are enclosed within and realize on the longeron of vehicle frame 1, as shown in Figure 2.Four square tubes 4 are distributed in four angles in compartment 2, and they are enclosed within on the longeron of vehicle frame 1 simultaneously.Square tube 4 can be with the front and back longitudinal sliding motion on longeron of same compartment 2.

For making automobile when there is head-on crash, can extend the inertia energy that compartment 2 had at that time, the release distance on time and space, reduces the impact dynamics that in compartment, personnel bear, and protects more preferably the full complement in compartment.The present invention has taked following technical measures: automobile primary will be divided into

vehicle frame

1 and 2 liang, compartment major part, compartment 2 horizontal anomalous movements are connected on vehicle frame 1, between vehicle frame 1 and compartment 2, push rod energy absorber 3 is housed, push rod energy absorber 3 is short by there being length to have, with long have wall scroll or many push rods, combine, the push rod of push rod energy absorber 3 is arranged between compartment 2 and vehicle frame 1, as shown in Figure 1; Owing to being horizontal anomalous movement annexation between vehicle frame 1 and compartment 2, between vehicle frame 1 and compartment 2, push rod energy absorber 3 is housed simultaneously, so when automobile under steam head-on crash occurs, compartment 2 is under the effect of inertia, occurring is forward that vertical equity moves with respect to vehicle frame 1.This vertical equity displacing force forward, can push push rod energy absorber 3 forward.Due to push rod energy absorber 3 have long have short, in a time, the power that withstands shocks only have relatively long push rod (being non-whole push rod).Simultaneously because push rod energy absorber 3 bearing capacity relatively long or equal length is less than compartment 2 these vertical equity displacing forcies forward, thus push rod from long to short one by one or many isometric push rods by compartment 2 distortion of bending.The isometric push rod of every press-bending one or more, compartment 2 all will consume a part of inertia energy.The inertia energy that so just can make compartment 2 have is discharged slowly, extends the inertia energy in compartment 2, and the release distance on time and space, has reduced the impact dynamics that compartment and interior passenger thereof are born.

The principle of work of this programme: when automobile generation frontal impact, due to the effect of inertia, compartment 2 can be with respect to vehicle frame 1 parallel motion forward.This displacing force, pushes the push rod energy absorber 3 being contained between the two forward.Push rod energy absorber 3 is by different in size, with long, wall scroll or many, consists of.With the bearing capacity of long wall scroll or many push rods, be less than the impulsive force in compartment 2, so longer push rod is first bent, to being finally all bent.The isometric push rod of every press-bending one or more, compartment 2 all will consume a part of inertia energy.The inertia energy that so just can make compartment 2 have is discharged slowly, extends the inertia energy in compartment 2, and the release distance on time and space, has reduced the impact dynamics that compartment and interior passenger thereof are born.
