Abstract
The invention discloses a new-type hexagonal inequilateral energy absorption box structure for a front anti-collision beam of an automobile. The new-type hexagonal inequilateral energy absorption box structure comprises a first V-shaped outer plate, a second V-shaped outer plate and a mounting support. The first V-shaped outer plate and the second V-shaped outer plate are connected with each other in a welded mode. The end of the first V-shaped outer plate after connection is welded to the mounting support. The new-type hexagonal inequilateral energy absorption box structure is characterized in that the two sides of the V-shaped outer plates of an energy absorption box are provided with concave energy absorption ribs. The middle position of the upper end face of the first V-shaped outer plate and the middle position of the lower end face of the second V-shaped outer plate are provided with convex energy absorption ribs. The lengths of four sides of the side face of the energy absorption box are larger than those of two sides of the energy absorption box in the horizontal direction. The two sides, the upper portion and the lower portion of the energy absorption box are all provided with the energy absorption ribs, so it is guaranteed that collision energy crumples and is absorbed in all directions; the arrangement directions of the energy absorption ribs are different so that the crumple and energy absorption effect of an energy absorption box body can be improved; the spot welding connection technology is adopted for the energy absorption box structure, so that the new-type hexagonal inequilateral energy absorption box structure is convenient to manufacture and can fall off and deform easily to absorb the collision energy.
Description
technical field:
The present invention relates to a kind of vehicle energy absorption box, be specifically related to the energy-absorption box structure that the unequal-sided modern automobile front anti-collision beam of a kind of hexagonal is used.
background technology:
Collision safety performance is one of main contents of body structure safe design, main purpose is the degree that reduces to cause due to collision occupant injury, this requires body structure must possess the ability of energy-absorbing and resistance to deformation, while being collision happens, its collision energy must be absorbed by the privileged site of body construction, reduces as much as possible the acceleration/accel of Vehicular impact.
Energy-absorption box is the vitals that absorbs automobile collision energy, and for the central collision of self-supporting body, bumper beam and energy-absorption box can absorb the energy of 10% left and right.The design of energy-absorption box mainly considers to make it have suitable rigidity, the rigidity that reaches each parts is coordinated, if energy-absorption box rigidity more greatly, energy-absorbing is less, slows down very fast when vehicle is subject to moment impact, cause occupant to respond deceleration/decel and strengthen, be easy to reach the deceleration/decel damage limit that human body can bear; If energy-absorption box rigidity is less, in collision process, absorb little energy, thereby increase crew module's distortion reduces occupant's living space, harm occupant personal safety.
summary of the invention:
The energy-absorption box that the object of this invention is to provide a kind of Novel structure absorbs the collision energy from front anti-collision beam, plays buffer action, reduces vehicle injury to pedestrian and occupant in accident.
The technical solution used in the present invention is: the energy-absorption box structure that a kind of hexagonal scalene modern automobile front anti-collision beam is used, comprise the first V-type outside plate, the second V-type outside plate and mounting bracket, the first V-type outside plate and the second V-type outside plate are by being welded to connect, the first V-type outside plate end after connection is welded on mounting bracket, it is characterized in that: in the V-type outside plate both sides of energy-absorption box, be provided with the energy-absorbing muscle of spill, the lower surface midway location of the upper surface of the first V-type outside plate and the second V-type outside plate is provided with protruding energy-absorbing muscle.
Further, described energy-absorption box V-type outside plate side is also evenly arranged welding knock hole.
Further, described position of positioning hole and recessed energy-absorbing muscle are alternately.
Further, the length of described energy-absorption box side four edges is longer than the length on both sides in horizontal direction.
The beneficial effect that the present invention produces is: the both sides of energy-absorption box structure and the lower upper energy-absorbing muscle that all has, guarantee that collision energy is from all directions crumple energy-absorbing, the different crumple energy-absorbing effect that can improve energy-absorption box body of arranged direction of energy-absorbing muscle, between energy-absorption box structure, adopt spot welding to connect, be convenient to produce, the distortion that easily comes off absorbs collision energy.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
the specific embodiment:
Below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 1, the energy-absorption box structure that hexagonal scalene modern automobile front anti-collision beam is used is used spot-welding technology to be welded into a cuboid energy-absorption box structure for both sides opening by the first V-type outside plate 1 and the second V-type outside plate 2, and the high tensile steel plate cold stamping of practical 1.2 millimeters thick of V-type outside plate is shaped.One end at energy-absorption box is provided with flange, and is connected with energy-absorption box mounting bracket 3 by spot welding, uses spot welding to connect and is convenient to produce, and energy-absorption box is easily come off and be out of shape absorption collision energy.The other end carries out flange processing on protrusion, for being connected with bumper/spoiler.
Six angles in energy-absorption box all adopt circular arc type excessive, on energy-absorption box two sides respectively punching press have three spill energy-absorbing muscle 6 structures, this energy-absorbing muscle structural expression is semicylinder groove, at the boundary of groove surrounding, is provided with arc angling.In the upper surface of the first V-type outside plate 1 and the lower surface midway location of the second V-type outside plate 2, be provided with protruding energy-absorbing muscle 4, this energy-absorbing muscle is positioned at the centre of two spill energy-absorbing muscle 6, for guiding energy-absorption box upper surface and the lower surface crumple direction when energy-absorption box bumps energy-absorbing, improve the crumple energy-absorbing effect of energy-absorption box.
On the V-type outside plate of energy-absorption box, be also furnished with two welding knock holees 5, weld knock hole 5 between adjacent spill energy-absorbing muscle 6, the accuracy while conveniently welding in actual production process.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
