Description
Technical field
The utility model relates to automobile energy-absorbing technical field, particularly a kind of automobile-used energy-absorption box.
Background technology
Collision safety performance is one of main contents of body structure safe design, main purpose reduces owing to colliding the degree causing occupant injury, this requires that body structure must possess the ability of energy-absorbing and resistance to deformation, namely during collision happens, its collision energy must be absorbed by the privileged site of body construction, reduces the acceleration/accel of Vehicular impact as much as possible.Energy-absorption box is the vitals absorbing automobile collision energy, and for the central collision of self-supporting body, bumper beam and energy-absorption box can absorb the energy of about 10%.The design of energy-absorption box is mainly considered to make it have suitable rigidity, the rigidity reaching each parts is coordinated, if energy-absorption box rigidity is comparatively large, energy-absorbing is less, when vehicle is very fast by slowing down during moment impact, cause occupant to respond deceleration/decel to strengthen, be easy to reach the deceleration/decel damage limit that human body can bear; If energy-absorption box rigidity is less, then absorb little energy in collision process, increase the distortion of crew module thus the living space of reduction occupant, harm occupant personal safety.
Therefore the energy-absorption box being necessary to provide a kind of energy-absorbing effect when can increase auto against, reducing occupant injury.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, provides a kind of structure simple, automobile-used energy-absorption box reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of automobile-used energy-absorption box described in the utility model, comprise the first right angle plate and the second right angle plate, the two ends of two right angle plates are provided with anti-limit, the anti-limit of two pieces of right angle plates is fixedly connected by screw and nut, and it is foursquare square frame that described first right angle plate and the second right angle plate form a cross section; The inner chamber of this square frame is provided with the bulkhead of " well " word shape, and described bulkhead and square frame inwall are arranged with four areolas and four cavities, and four areolas are distributed on four angles of square frame inner chamber respectively, and described areola cross section is square shape; Four cavities are distributed on four limits of square frame inner chamber respectively, and described cavity cross section is oblong-shaped; The large cavity cross section of described bulkhead is square; Former and later two sidewalls of described bulkhead are provided with several the first guiding grooves along short transverse, and two, the left and right sidewall of described bulkhead is provided with several the second guiding grooves along short transverse.
Further, described first guiding groove is made up of the first guiding groove of to be the first rectangular-shaped guiding groove and multiple cross section be in multiple cross section arc shape, and the first rectangular-shaped guiding groove and the first guiding groove of arc shape are set in distance.
Further, described second guiding groove is made up of the second guiding groove of to be the second rectangular-shaped guiding groove and multiple cross section be in multiple cross section triangle, and the second rectangular-shaped guiding groove and the second guiding groove of triangle are set in distance.
After adopting said structure, the utility model beneficial effect is: a kind of automobile-used energy-absorption box described in the utility model, comprise the first right angle plate and the second right angle plate, the two ends of two right angle plates are provided with anti-limit, the anti-limit of two pieces of right angle plates is fixedly connected by screw and nut, and it is foursquare square frame that described first right angle plate and the second right angle plate form a cross section; The inner chamber of this square frame is provided with the bulkhead of " well " word shape, and described bulkhead and square frame inwall are arranged with four areolas and four cavities, and four areolas are distributed on four angles of square frame inner chamber respectively, and described areola cross section is square shape; Four cavities are distributed on four limits of square frame inner chamber respectively, and described cavity cross section is oblong-shaped; The large cavity cross section of described bulkhead is square; Former and later two sidewalls of described bulkhead are provided with several the first guiding grooves along short transverse, and two, the left and right sidewall of described bulkhead is provided with several the second guiding grooves along short transverse.When using the utility model, being enclosed to form foursquare square frame by two right angle plates, improve the energy-absorbing effect of energy-absorption box; By bulkhead every establishing multiple empty frame, enrich the energy-absorbing effect of energy-absorption box; Guiding bulkhead initiatively energy-absorbing by being provided with multiple guiding groove on the sidewall of bulkhead, strengthening energy-absorbing effect further, reducing the injury to occupant, ensureing occupant's personal safety.It is simple that the utility model has structure, arranges rationally, the advantages such as cost of manufacture is low.
