Connect and transit to rear mounting plane and supporting sleeve and the matching welding of front-axle beam bottom sheet.Although such a structure meets its structural strength
And assembly reliability, but it is poor to vehicle frontal collision energy-absorbing effect.When head-on crash occurs for vehicle, due to fore sub frame knot
Structure is stronger, and longitudinal rigidity is very big, could not effectively deform, and causes the part of enging cabin to invade driving cabin, and occupant's person is pacified
It is complete very unfavorable.
Utility model content
In order to solve above-mentioned technical problem, the fore sub frame back segment that the utility model devises a kind of passenger car touches
Hit endergonic structure.
In order to solve above-mentioned technical problem, the utility model employs following scheme：
A kind of fore sub frame back segment collision energy-absorbing structure of passenger car, including under subframe front-axle beam upper piece, subframe front-axle beam
Supporting sleeve is installed, the subframe front-axle beam upper piece and the subframe front-axle beam bottom sheet snap together, and it is special after piece and vehicle body
Sign is that the left and right ends in the subframe front-axle beam upper piece back segment region and the subframe front-axle beam bottom sheet back segment region are bent backward
Folding extends and forms front wide and rear narrow " V " font structure respectively, and mounting hole is machined with respectively to pacify on the end of " V " font structure
Supporting sleeve is installed after filling the vehicle body.
Further, the subframe front-axle beam upper piece and the subframe front-axle beam bottom sheet snap together to form hollow structure；
Matching welding is fastened on the outside of the subframe front-axle beam upper piece and the subframe front-axle beam bottom sheet or so, inner side is turned over using corresponding
Side or flange surface matching welding.
Further, the subframe front-axle beam upper piece and the subframe front-axle beam bottom sheet are stamped to form using high-strength steel sheet.
Further, mounting plane after the subframe front-axle beam bottom sheet bottom surface is seamlessly transitted to vehicle body.
The fore sub frame back segment collision energy-absorbing structure of the passenger car has the advantages that：
（1）The utility model is rational in infrastructure, and it is installed after being seamlessly transitted by fore sub frame body " V " type face to vehicle body
Face, a coherent load transfer path is formed from A-P, is advantageous to the transmission of suspension link power.Work as vehicle frontal collision
When, subframe rear end itself " V " type architectural feature is come from, fore sub frame can be downward in greater impact load lower edge " V " type structure
Bending deforms, and effectively absorbs potential energy.The effective collision of subframe is deformed so as to guide engine compartment components to vehicle bottom
Portion deforms or conquassation, and then avoids engine nacelle part from invading to driver's cabin the personal safety for threatening passenger.
（2）The utility model is simple in construction, easy to process, practical.
