Car device.
Background technology
As World Economics is fast-developing, automobile already turns into a kind of modern transportation instrument become increasingly popular, and automobile is protected
While the amount of having increases sharply, the traffic accident brought therewith is similarly increasingly serious.Therefore, the safety to automobile is puted forth effort by country
Property carry out in-depth study, automotive safety be divided into actively and passively safety, active safety generally refer to automobile prevention or avoid
The performance of accident, passive security refers to the ability that collision avoids occupant from coming to harm after occurring.Wherein passive security is national
Main study subject, nowadays passive security research relies primarily on Computer Simulation and vehicle impact testing to complete, then automobile
Cost required for the experiment of full scale vehicle collision is huge, and the test period is long, in this regard, simulative automobile emulation impact test has come into vogue
Come, with devices such as impact walls, chassis, traction, release, guide rails, impulsive force is directly given to the experiment position of instruction carriage, so that
Identify the performance at the position.
Wherein as the collision mechanism for bearing automobile seat of simulative automobile impact test critical equipment, chassis is set
Meter has all played certain influence to putting and arranging for final testing equipment.Existing measure is to adopt double rollers mechanism, is utilized
Double guide rails are guided to collision chassis, and the place of occupancy is larger, is not suitable for the arrangement of small plant or laboratory test room, and
Cost also increases.
The content of the invention
On the premise of ensureing crash tests performance there is provided one kind it is an object of the invention to the shortcoming for overcoming prior art,
Effectively reduce the chassis of the simulative automobile impact test of cost.
In order to solve the above technical problems, present invention employs following technical measures：

Collision block, plummer, the idler wheel mechanism are located at the impingement plate bottom, and the Impactor is located at the collision end of the impingement plate
On, the plummer is on the impingement plate, and the idler wheel mechanism includes several wheel carrier groups, and each wheel carrier group includes
Two wheel carriers for being oppositely arranged；Each wheel carrier includes the first roller, the second roller, the first roller and places plate, the second roller
Place plate and connection first roller places the wheel carrier connecting plate that plate places plate with second roller；First roller
The first surface of the guide rail is slideably positioned in, second roller-coaster is arranged at the second surface of the guide rail, makes each
The wheel carrier is in clamp position with the guide rail.
The present invention can also be further perfect by following technical measures：
As a further improvement, the guide rail is independent one, and it is I-shaped perpendicular to the cross section on ground
Guide rail.
As a further improvement, " work " the font guide rail includes arc on first surface straight in top ends, side of sidewall portion
The second surface of shape.
As a further improvement, first roller places the first roller connection that plate further comprises perpendicular setting
Piece, second roller places the second roller connection sheet that plate further comprises perpendicular setting.
Set as a further improvement, first roller places plate with the wheel carrier connecting plate right angle, second rolling
Wheel is placed plate and set in obtuse angle to inner side with the wheel carrier connecting plate；First roller and the guide rail top ends are straight the
One slidably contacts the surfaces；The second surface sliding contact of second roller and arc in the rail-sides wall portion.
As a further improvement, the wheel carrier connecting plate inwall side is coated with composite, between reduction and guide rail
Friction.
As a further improvement, the impingement plate further comprises collision draw hook with reclaiming draw hook.
As a further improvement, having a lug boss below the connecting plate, the lug boss is located under the impingement plate
The middle part of side；The collision draw hook is on the lug boss；The recovery draw hook is located to be touched with the connecting plate
Hit and hold on relative end.
As a further improvement, the draw hook is closed type hook, the recovering hook is semiclossed hook.
Compared with prior art, the present invention has advantages below：
1. the idler wheel mechanism of chassis clamps guide rail using wheel carrier structure, guide rail uses work " font single-rail, its top has
The second surface of arc, is used cooperatively with wheel carrier structure on straight first surface and side of sidewall portion.So that idler wheel mechanism is with leading
Rail connection is more consolidated, and prevents that silver-colored chassis acceleration is excessive in process of the test, makes chassis derail, causes unnecessary accidental wound
Evil.
2. guide rail uses the cross section perpendicular to ground for the single-rail of I-shaped, guide rail floor space is saved, from
And reduce the space of experimental site.
3. the inwall of wheel carrier part scribbles composite, chassis is reduced between sliding process middle guide and idler wheel mechanism
Frictional force.
It is to lose company with chassis in experiment to prevent that rope etc. from drawing medium 4. collision draw hook is designed as closed type hook
Connect, cause the failure of an experiment.
5. reclaiming draw hook is designed as semiclossed hook so that the traction medium of such as rope is detachable at any time, and it is anti-to be
Only chassis causes chassis to be influenceed in distraction procedure by additional friction because the dissolution mediums such as rope are too short in an experiment, causes
Experimental result is inaccurate；Or experiment is interfered because dissolution medium is caught in track.
