Description
Technical field
The utility model is related to a kind of auto-safety mechanism, especially a kind of automobile inherently safe anticollision spring delays again
Rush energy absorber.
Background technology
Traditional automobile front/rear collision bumper is the safety device being mainly made of metal materials, the steel for being 3 millimeters or more with thickness
Plate strikes out U-lag steel, is surface-treated chromium plating, rivets or welds together with longitudinal beam, with vehicle body have one section it is larger between
Gap reduces the injures and deaths of vehicle collision damage and driver and conductor to buffer fast running vehicle accident collision cushion impact forces.With
Auto industry development and engineering plastics in the extensive application of auto industry, bumper is as a kind of important safety dress
Set the road for also having moved towards innovation.Automobile front/rear collision bumper is other than keeping original defencive function at present, also to pursue and vehicle
Figure modelling harmony with uniformly, the lightweight of pursuit itself.The front/rear collision bumper of car is all made of plastics, and people are known as moulding
Expect bumper.Wherein outside plate and padded coaming is made of plastic, crossbeam thickness for 1.5 millimeters or so flat cold-rolled sheet punching press and
At U-lag；Outside plate and padded coaming are attached on crossbeam, and crossbeam and longitudinal beam screw connection can disassemble at any time.This
Although the bumper of kind of structure is beautiful, its buffer capacity is inadequate, and especially when speed hits and touches, cushion effect is inadequate, can still give
Vehicle and driver and conductor make or compared with major injuries.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of automobile itself peace of cushion effect bigger
Full anticollision spring buffering energy-absorbing device again.The purpose of this utility model is realized by following technical proposals：A kind of automobile from
The safe anticollision spring of body buffering energy-absorbing device, including motor, U-lag steel, U-lag steel and longeron the fixation company as crossbeam again
It connects, it is characterised in that：Two longeron front of automobile is respectively fixedly connected with a flexible stem casing seat, and block set bottom is equipped with spring, telescopic rod one
End is fixedly connected with buffer bumper, and the other end passes through the through hole and telescopic rod block set oral area in U-lag steel to be socketed, on telescopic rod
Equipped with rack, it is fixedly connected with both-end driving motor equipped with a holder between two longeron of automobile, both-end driving motor shaft end is affixed
There is gear to be engaged with the rack on telescopic rod, both-end driving motor admittance line is switched with the motor system of falling sequence and power supply is connected, and stretches
Contracting bar side face is equipped with locking and positions semi-circular recesses, and the position side after groove retraction is equipped with the lock device with top spring, lock device
Steel ball offset with semi-circular recesses.
The operational process of the utility model is as follows, when automobilism need to protract buffer bumper, is opened by the way that motor is suitable
The positive indexing closed makes both-end driving motor start to rotate forward, and the rack taken on telescopic rod using motor shaft ends gear is to projecting forwardly to
U-lag steel front 30-40cm closes motor, before automobile occurs when collision, carries out energy-absorbing buffering by spring, mitigates vehicle
Collsion damage and the interior driver and conductor of protection.When buffer bumper is stopped transport or need to be bounced back to automobile, pass through motor two-direction switch
Position is reversed, so that motor both-end driving motor is inverted, making automobile inherently safe anticollision spring, buffering energy-absorbing device is back to U-lag again
It at steel, and is offseted by the steel ball of locking spring at front end and the semi-circular recesses of telescopic rod side, reaches locking purpose.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Specific implementation mode
As shown in Figure 1, a kind of automobile inherently safe anticollision spring buffering energy-absorbing device again, including motor, as crossbeam
U-lag steel 3, U-lag steel is fixedly connected with longeron 5, it is characterised in that：Two longeron front of automobile is respectively fixedly connected with a telescopic rod
Block set 7, block set bottom are equipped with spring 8, and spring top power is in 0.5-1kg/cm2, 2 one end of telescopic rod is fixed with buffer bumper 1 to be connected
It connects, the other end passes through the through-hole 9 in U-lag steel to be socketed with flexible stem casing seat oral area, and telescopic rod is equipped with rack 4, in automobile two
It is fixedly connected with both-end driving motor 16 equipped with a holder 15 between longeron, both-end driving motor shaft end is connected with gear 10 and stretches
Rack 4 on bar engages, and both-end driving motor admittance line 11 is connected with the motor system of falling sequence switch 12 and power supply, telescopic rod side
Semi-circular recesses 14 are positioned equipped with locking, the lock device 6 with top spring is fixedly connected on the position lateral vertical beams after groove retraction,
Its concrete structure is that spring is equipped in tubulose locking body, is equipped with steel ball 13 on spring, tubulose lock device oral area passes through thread bush
A closing in set is connect, to prevent steel ball from deviating from, and makes steel ball have 1/3 exposing to close up and covers, steel ball exposed portion and telescopic rod side
Semi-circular recesses offset.
