Abstract
The invention discloses a frame side-impact limiting device for SUVs (sport utility vehicles), which comprises a frame longitudinal beam and a body B pillar. The limiting device disclosed by the invention is characterized in that a steel side-impact limiting box consisting of a top plate, a left side plate, a bottom plate, a right side plate and an outer plate is fixed on the external sidewall ofthe frame longitudinal beam in front of the body B pillar, under a driver seat, and at a position close to a point R so as to improve the rigidity of the side-impact limiting box. The side-impact limiting box can participate in the absorption of impact energies during the early and middle periods of impact, thereby reducing the requirements on the quantity of absorbed impact energies of body parts such as the body B pillar, a body floor and a side body, and the like, namely, correspondingly reducing the rigidity demands for the body parts, reducing the complexity of the body structure, and lowering the process requirements of the body. By using the side-impact limiting device disclosed by the invention, when a side impact occurs to vehicles, impact energies can be transferred to the framelongitudinal beam as many as possible and then absorbed efficiently so as to reduce the damages to a body passenger cabin; and the side-impact limiting device has the advantages of less investment and low cost, therefore, the side-impact limiting device is suitable for non-stressed SUVs.
Description
Technical field
The present invention relates to automobile equipment, especially relate to a kind of SUV vehicle frame side impact inhibiting device.
Background technology
Development along with international and domestic automotive technology; The passive satety of automobile is more and more paid attention to by people; And new car crash tests (NCAP) test has become and has weighed an advanced important indicator of vehicle technology, and wherein side impact is again wherein a kind of main test method (three kinds of collision modes altogether: 1, positive 40% overlapping deformable obstacle Collision test; 2, the test of obstacle side collision is moved in deformable; 3, positive 100% overlapping rigidity obstacle Collision test).For a kind of non-bearing formula SUV (sports type multipurpose automobile); Passenger cabin safety method during side impact; Mainly be absorbing impact that can column (being center body pillar), body side wall intensity and vehicle frame between vehicle body Qianmen and the vehicle body back door as much as possible can so that when side collision takes place, protect personnel's in the passenger cabin personal safety.But; Tradition non-bearing formula SUV moves the requirement of the Collision test of obstacle side in order to reach deformable; Will increase of the requirement of vehicle body parts such as center body pillar, body platform and gusset, thereby the rigidity that has significantly improved these bodywork parts requires and the vehicle body technological requirement, makes body structure become more complicated to impact absorption energy number; Manufacturer will drop into huge fund for this reason, and the cost of automobile is significantly improved.
Summary of the invention
The object of the present invention is to provide a kind of can improve automobile when side collision takes place with more collision energy be delivered on the frame beam as soon as possible, efficient absorption side impact energy with reduce the injury of vehicle body passenger cabin, keep simultaneously that contour of the vehicle is attractive in appearance, less investment, SUV vehicle frame side impact inhibiting device that cost is low.
The objective of the invention is to realize like this:
A kind of SUV vehicle frame side impact inhibiting device; Comprise at the chassis side rail below the body bottom panel with between vehicle body Qianmen and vehicle body back door, fix and the center body pillar vertical with chassis side rail; Characteristic is: under the chassis side rail lateral wall in center body pillar the place ahead, operating seat, near the side impact position-limited box of R point stationkeeping by the steel of being made up of top board, left side board, base plate, right side board and outside plate, to improve the rigidity of side impact position-limited box.
The distance of the outside plate of side impact position-limited box inwall apart from the vehicle body Qianmen is 50--58mm.
When vehicle when the Collision test of obstacle side is moved in deformable; Collision acts on center body pillar earlier; Treat B-pillar deformation to the position of side impact position-limited box the time (the lateral deformation displacement is L), also do not knock before the chaufeur; The side impact position-limited box begins the absorbing impact energy, and because the rigidity very high (far above side impact position-limited box and body platform) of chassis side rail, so find the distortion of crumple formula in side impact position-limited box collision back; The minimum purpose (chassis side rail can not produce the cross travel distortion basically) of distortion when reaching the efficient absorption collision energy, thereby the personal safety of chaufeur when side impact in the protection passenger cabin.
The present invention is because under the lateral wall of chassis side rail, operating seat, increased the side impact position-limited box near R point position; And make it participate in the absorbing impact ability in the prometaphase of collision; Reduced of the requirement of vehicle body parts such as center body pillar, body platform and gusset to impact absorption energy number; Be the corresponding rigidity requirement that has reduced these vehicle body spares, reduced complicated body structure, reduced the vehicle body technological requirement.Simultaneously; Because car load also need satisfy other two Collision test requirements; So the structure of chassis side rail needn't be done special change for side impact, has only increased the side impact position-limited box in the side of chassis side rail, reached under efficient absorption side impact energy prerequisite few and dropped into, purpose cheaply.R point definition: the R point is a seating reference point, and its location definition does, with seat transfer at last, extreme lower position; The R point is in seat center of symmetry face; The vertical tangent line of back of seat and the intersection point of seat are the G point, be the R point (there is difference in out-of-position distance according to every kind of vehicle of design master layout, and is concrete selected selected according to factors such as manikin, seat soft or hard degree, pedal positions from the G point segment distance that squints forward and upwards; Generally can upwards lift 45～70mm) to reach 100mm.
The present invention have can improve automobile when side collision takes place with more collision energy be delivered on the frame beam as soon as possible, efficient absorption side impact energy with reduce the injury of vehicle body passenger cabin, keep simultaneously that contour of the vehicle is attractive in appearance, less investment, advantage that cost is low, be applicable to that non-bearing formula SUV uses.

The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the present invention is done further explain.
A kind of SUV vehicle frame side impact inhibiting device; Comprise at the chassis side rail below the body bottom panel 85 with between vehicle body Qianmen 1 and vehicle body back door 3, fixing and vertical center body pillar 6 with chassis side rail 5; Under chassis side rail 5 lateral walls in center body pillar 6 the place aheads, operating seat 2, near the side impact position-limited box 7 of R point 4 stationkeeping, to improve the rigidity of side impact position-limited box by the steel of forming by top board 10, left side board 9, base plate 12, right side board 13 and outside plate 11.
The distance L of the outside plate 11 of side impact position-limited box 71 inwall apart from the vehicle body Qianmen is 50--58mm.
