Detailed description of the invention
As Figure 1-Figure 5, the present invention is a kind of coach frontal collision breakdown contraction mechanism, and it comprises collision prevention girders 1, energy-absorption box 2, energy-absorption box guide plate 3, Connection Block 6, chassis side rail 7, longeron strengthen box 8 and crashproof support beam 9.
Described energy-absorption box 2 is rectangle or square hollow member, and its outer wall is at least provided with more than 2 the induction grooves 21 be laterally parallel to each other.
Described energy-absorption box guide plate 3 is in " 7 types " component, and its tail end connects bearing 31 and collision prevention girders 1 Joint by first, and top is by the second connection bearing 32 and Connection Block 6 Joint; Described first connects the left and right end of bearing 31 is provided with flanging 311 along collision prevention girders direction, and this flanging 311 is welded to each other with collision prevention girders 1.
Described longeron strengthen box 8 is the hollow member of a rectangle, is at least provided with the annular recess 81 of one or more outside it, and annular recess offers 4 induce pores 82 relative with longeron strengthen box four end points.
Described Connection Block 6 is the hollow triangular prism component of inclined-plane, one end opening, one right-angle surface 61 is mutually affixed with energy-absorption box 2, second bearing 32, it is mutually affixed with chassis side rail 7 that its another right-angle surface 62 connects bearing 33 by the 3rd, described hollow prism inside is provided with some reinforced ribs 63, its each connecting end surface offers some lightening holes 64, adopt above-mentioned design, can under the prerequisite meeting Connection Block 6 integral rigidity, component is tried one's best lightweight.
Concrete assembly relation is as follows:
Crashproof support beam 9 is spirally connected with both sides car door upright column (not shown) by bolt by two tip inside of collision prevention girders 1 mutually, simultaneously left and right symmetric points connect bearing 31 respectively by first within it mutually affixed with the tail end of energy-absorption box guide plate 3, the top of its energy-absorption box guide plate 3 connects bearing 32 by second and is fixed in a right-angle surface 61 of Connection Block 6; Two energy-absorption boxes 2 are arranged on the bottom of energy-absorption box guide plate 3, its one end is fixed on energy-absorption box guide plate 3, and be positioned at energy-absorption box guide plate 3 and be connected on the joint face of bearing 31 with first, its other end is fixed in a right-angle surface 61 of Connection Block 6, angular range simultaneously between this energy-absorption box 2 line of centers and horizon is :-15 ° ~ 27.5 ° (referring to Fig. 6, arranging according to the height that collision prevention girders is installed); Connection Block 6 connects bearing 33 by the 3rd and is mutually spirally connected with chassis side rail 7.
Described longeron strengthen box 8 is bolted the front that is arranged on chassis side rail 7 and is positioned at the inside front of collision prevention girders 1.
Adopt above-mentioned design, when passenger vehicle front portion collides, if collision object height is lower, as small passenger car etc., often first collision prevention girders collides contact, then its impulsive force is backward connected bearing by first and be passed to energy-absorption box guide plate, because energy-absorption box guide plate is " 7 types " component, can guarantee that impulsive force major part is transmitted along energy-absorption box crumple direction, simultaneously because collision prevention girders the inner is connected with crashproof support beam, the car door upright column of this crashproof support beam and both sides is spirally connected mutually, a seal force ring is formed with car door upright column, make like this in collision process, collision prevention girders, first connects bearing, energy-absorption box guide plate and energy-absorption box create damaged deformation, absorb most collision energy, and car door upright column and chassis side rail deflection all less, improve the traffic safety performance of passenger vehicle.
When the object height of passenger vehicle collision is higher, as knocked into the back between passenger vehicle and passenger vehicle, except buffering, the energy-absorbing function of collision prevention girders mentioned above and other parts, its longeron strengthen box arranged in collision prevention girders upper inner also can produce buffering, energy-absorbing function, can greatly reduce the impact that chassis side rail is caused like this, reduce its distortion, the traffic safety performance of passenger vehicle can be substantially increased.
Above-mentioned frontal collision breakdown contraction mechanism major part adopts screw connection manner to assemble simultaneously, is conveniently convenient to repair or replace this mechanism when passenger vehicle.
Emphasis of the present invention is just: between collision prevention girders and Connection Block, be provided with energy-absorption box and energy-absorption box guide plate, simultaneously in the upper inner of collision prevention girders, can set up a longeron strengthen box mutually affixed with longitudinal bracket.
The above, be only present pre-ferred embodiments, therefore can not limit scope of the invention process with this, and the equivalence namely done according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
