Description
1 technical field
The present invention relates generally to the vehicle safety design field, refers in particular to the telescopic bumper of a kind of segmentation, and this structure can absorb more collision energy, the impulsive force of mitigation collision when bumping.
2 background technologies
Vehicle bumper is a kind of safety device that is fixed on position, various automobiles front and back.Existing vehicle bumper links together with longeron and rigidity of vehicle body based on materials such as metal, plastics, glass-felt plastics, can play certain protective role to driver and conductor and vehicle when low speed collision takes place.But when vehicle generation high speed head-on crash, the effect of bumper/spoiler is just very limited, and its basic reason is that the traditional insurance thick stick does not have endergonic structure basically.At present, though existing people proposes the extension type bumper structure, its principle of work is by the automatic telescopic buffer of existing Federal bumper and certain is connected, and this shock absorber adopts hydraulic pressure or pressure system more.When collision happens, shock absorber can produce certain buffering energy-absorbing effect.Yet this extension type bumper complex structure, cost are higher, and because this telescopic bumper/spoiler is to release bumper/spoiler is whole, the load that this will increase telescoping mechanism is unfavorable for the layout of bumper/spoiler lamp, and car load front portion moulding is destroyed after stretching out.
3 summary of the invention
The structure that the purpose of this invention is to provide the scalable bumper/spoiler of a kind of segmentation, this structure can be expanded the energy-absorbing space of automotive front end, absorb collision energy, slow down the impulsive force of collision.
The purpose of segmented extension type bumper energy absorption structure of the present invention is achieved in that and it is characterized in that power-absorbing (16) is connected between segmentation bumper/spoiler (18) and the retractor device; The bumper/spoiler retractor device is by shell (5), the feed screw nut (11) and the self-locking key seat (12) that can in shell (5), slide, make the screw mandrel (4) of feed screw nut (11) motion, with feed screw nut (11) bonded assembly spring pin (3) and the propelling skewback (2) that is fixed on spring pin (3) front end with nut, be supported on and advance the self-lock pin (1) that skewback (2) is gone up and self-locking key seat (12) is interior, self-locking key seat (12) stroke stop-motion seat (13) foremost, spring compositions such as (14) on spring pin (3) and the self-lock pin (1); The shell of bumper/spoiler retractor device (5) places in the car longeron (9), and connects with the outer most edge of bolt with longeron (9); Power-absorbing (16) is connected on the self-locking key seat (12) with screw, and iron (17) is welded on the power-absorbing (16) of the left and right sides in the bumper/spoiler, and the side shield (19) in interior iron (17) outside links to each other with longeron (9) outside by slide rail (15); Segmentation bumper/spoiler (18) is fixed on interior iron (17) of bumper/spoiler and the side shield (19) for extended section.This invention realizes stretching out and recovery movement of energy absorber by the rotating of motor (8).When bumping,, expand the energy-absorbing space, absorb more collision energy, can effectively reduce the impaired of occupant's damage and car body by the conquassation distortion of the power-absorbing (16) that stretches out; When do not bump and dangerous the elimination after, can regain segmentation bumper/spoiler (18) and power-absorbing (16) by the counter-rotating of automatically controlled realization motor (8), make the front part of vehicle reinstatement.
Described segmentation bumper/spoiler (18) only intercepts the part of bumper/spoiler, and concrete size can be determined according to each vehicle.
Described power-absorbing (16), its structural shape and length are to be decided by its energy size that will absorb.
Described slide rail (15) is the two-section type telescopic rail, and sub-guide rail is extracted out from female guide rail when stretching out, and sub-guide rail slips into female guide rail during withdrawal.
The impact load decision that the number of described self-lock pin (1) will be born by this mechanism.
The horizontal component of force of described self-lock pin place spring (14) is greater than the horizontal component of force of spring pin place spring (10).
Compared with prior art, advantage of the present invention just is:
1, segmented extension type bumper energy absorption structure of the present invention can bear bigger impact load, and energy actv. assurance driver and conductor's life security and reduction are to the destruction of vehicle;
2, segmented extension type bumper energy absorption structure of the present invention, simple and compact for structure, with low cost, good reliability.

The specific embodiment
Below with reference to the drawings and specific embodiments the present invention is described in further details.
As shown in Figure 1, segmented extension type bumper energy absorption structure of the present invention, it comprises segmentation bumper/spoiler (18), power-absorbing (16), interior iron (17), side shield (19), slide rail (15), self-lock pin (1), self-locking key seat (12), stop-motion seat (13), advances skewback (2), self-lock pin spring (14), spring pin (3), spring pin spring (10), back backing block (13), screw mandrel (4), feed screw nut (11), shell (5), motor (8), motor fixing plate (7).In the present embodiment, motor (8) is fixed on the motor fixing plate (7), and motor fixing plate (7) is connected with shell (5) with screw, and the mouth of motor (8) is connected with screw mandrel (4) with holding screw.Mechanism is when stretching out stroke, motor (8) just changes, drive screw mandrel (4) and drive feed screw nut (11), the spring pin (3) that is with spring (10) is threaded on the feed screw nut (11), its front end connects propelling skewback (2) with bolt arrangement, and it is certain to make both remain distance, and self-lock pin (1) bottom support is on the inclined-plane that advances skewback (2), top places in the self-locking key seat (12), is with self-lock pin spring (14) on the self-lock pin (1).Because self-lock pin upper spring (14) is given the power of self-locking key seat (12) greater than spring pin upper spring (10) to the horizontal force that advances skewback (2), then spring pin (3) is promoting self-locking key seat (12) and is travelling forward, meanwhile, power-absorbing (16) and segmentation bumper/spoiler (18) also travel forward along with the motion of self-locking key seat (12).When self-locking key seat (12) reach stroke foremost the time, because self-locking key seat (12) has been limited motion by stop-motion seat (13), and feed screw nut (11) still travels forward, feed screw nut's this moment (11) overcomes on the spring pin (3) and self-lock pin (1) upper spring power travels forward propelling skewback (2), and then the self-lock pin (1) of its top of jack-up inserts self-lock pin (1) top to realize self-locking in the stop-motion seat (13), and segmentation bumper/spoiler (18), power-absorbing (16) and self-locking key seat (12) have also been realized locking.In this process, because side shield (19) and interior iron (17) welding, and side shield (19) connects with longeron (9) by slide rail (15), so slide rail (15) has played the motion guide effect, realization mechanism stretches out along horizontal direction.Motor (8) counter-rotating during the mechanism backhaul, screw mandrel (4) drives feed screw nut (11) and moves backward, feed screw nut (11) drives and advances skewback (2) to move backward, self-lock pin (1) moves down the realization release, after advancing skewback (2) and self-locking key seat (12) contacting, feed screw nut (11) moves backward by propelling skewback (2) the drive self-locking key seat (12) of spring pin (3) front end, and then move behind the power-absorbing (16) that connects firmly of drive and self-locking key seat (12) and the segmentation bumper/spoiler (18), realize segmentation bumper/spoiler (18) recovery movement, till running into back backing block (6), finish the withdrawal stroke of mechanism.
