Abstract

The utility model relates to a safety collision energy absorber for an automobile, which is characterized in that the safety collision energy absorber for an automobile comprises a beam and an energy absorbing longitudinal beam connected with the beam, wherein the energy absorbing longitudinal beam is connected with the front part of a longitudinal beam of an automobile frame. The energy absorbing longitudinal beam forms a hollow pipe shape. The wall of the energy absorbing longitudinal beam is provided with a guide buffering hole groove. The back part of the energy absorbing longitudinal beam is separated from the front part of the longitudinal beam of the automobile frame and is connected with the front part of the longitudinal beam of the automobile frame into a whole by a connector. The back part of the energy absorbing longitudinal beam is provided with an installation seat plate provided with an installation hole. The utility model has the advantages of prevention of defects of the prior art, convenient disassembly and replacement after collision, good maintainability, simple structure, low cost and high safety. Plastic deformation can be generated for reasonably absorbing energy, automobile damage can be reduced, and the safety of drivers, passengers and the automobile can be effectively protected.

Description

The automobile safety collision energy absorber
Technical field
The utility model relates to a kind ofly can produce plastic deformation, reasonable endergonic automobile safety collision energy absorber when automobile generation head-on crash.
Background technology
Existing automotive front has all designed a buffering energy-absorbing district, promptly mainly finish by the front area of vehicle frame, this technology is to produce plastic deformation by car body longeron front area to absorb energy, and by the constraint of constrained system to the driver and conductor, comes to harm thereby reduce the driver and conductor.Because buffering energy-absorbing structure becomes integral body with automobile body welding, in case bump, though can effective deformation, buffering energy-absorbing, the effective safety of protection chaufeur, but the longeron front portion has produced plastic deformation, be difficult to repair or rehabilitation cost too high, promptly enable to repair, also can't reach former car requirement; Chinese patent 00217209.7 discloses the patent application that name is called " vehicle collision buffer gear ", this application is to produce elastic deformation when utilizing auto against to shrink, thereby the impact energy that produces when absorbing collision, reach the automobile damage rate when alleviating auto against, avoid or alleviate the purpose of automobile driver and conductor's injures and deaths, though this crusherbull zone mechanism is simple in structure, replaceable, but the elastomeric material of its use can only play temporary transient buffer action, and elastic element is out of shape the back by compression and returns energy reserve, and distortion finishes, and the energy of deposit is most of to be discharged, cause the vehicle bounce-back, vehicle and chaufeur are caused the secondary injury.
Goal of the invention
The purpose of this utility model just provide a kind of can dismounting and change, simple in structure, cheap, safe and reliable, can produce plastic deformation and rationally absorb energy, reduce the effectively automobile safety collision energy absorber of protection driver and conductor safety of automobile damage thereby reach.
Solution of the present utility model is such: the energy-absorbing longeron that includes crossbeam and join with crossbeam, the energy-absorbing longeron is connected with the automobile chassis frame longeron is anterior, be the global formation in collision energy-absorbing district with original automobile chassis frame longeron front portion or be welded to connect and change isolating construction into, be that described energy-absorbing longeron is a hollow tubular, on the wall of energy-absorbing longeron, have guiding buffering hole slot; The rear portion of energy-absorbing longeron and automobile chassis frame longeron leading portion from, be connected as one by connector.
The utility model has the advantages that: the defective that can avoid prior art; after collision, make things convenient for dismounting and change; has good maintainability; simple in structure, cheap, safe and reliable; can produce plastic deformation and rationally absorb energy, reduce the effectively automotive safety of protection driver and conductor safety of automobile damage.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is structural representations of guiding buffering hole slot 6 in the accompanying drawing 1.
Accompanying drawing 3 is that energy-absorbing longeron 4 cross sections are square structural representation.
Accompanying drawing 4 is that energy-absorbing longeron 4 cross sections are circular structural representation.
Accompanying drawing 5 is that energy-absorbing longeron 4 cross sections are polygonal structural representation.
The specific embodiment
The utility model includes crossbeam 1, preceding shrouding 2, upper cover plate 3, energy-absorbing longeron 4, installation seat plate 5, guiding buffering hole slot 6, mounting hole 7.
Described energy-absorbing longeron 4 is a hollow tubular, has guiding buffering hole slot 6 on the wall of energy-absorbing longeron 4; The rear portion of energy-absorbing longeron 4 and automobile chassis frame longeron leading portion from, be connected as one by connector.The energy-absorbing longeron 4 that includes crossbeam 1 and join with crossbeam 1, energy-absorbing longeron 4 is connected with the automobile chassis frame longeron is anterior, it is characterized in that described energy-absorbing longeron 4 is hollow tubular, has guiding buffering hole slot 6 on the wall of energy-absorbing longeron 4; The rear portion of energy-absorbing longeron 4 and automobile chassis frame longeron leading portion from, be connected as one by connector.
Be provided with installation seat plate 5 in the rear end of described energy-absorbing longeron 4, on installation seat plate 5, have mounting hole 7, energy-absorbing longeron 4 and automobile chassis frame longeron front portion are connected as one with bolt.
Described energy-absorbing longeron 4 is a kind of of square tube shape, oblong tubulose, round tubular, polygon tubulose, oval tubular.
Guiding buffering hole slot 6 is to be distributed on the perisporium of energy-absorbing longeron 4, can be distributed on two sides, three or the four sides perisporium, and best situation is to be distributed on two of symmetry faces the wall and meditates,
In embodiment of the present utility model, described guiding buffering hole slot 6 is the front portions that are positioned at energy-absorbing longeron 4.
In the structure shown in the accompanying drawing 1; described guiding buffering hole slot 6 is the guiding compression muscle that concave; its manufacturing process is that preceding shrouding 2 and 4 of energy-absorbing longerons are welded into one; then with upper cover plate 3 spot welding; make energy-absorbing longeron 4 tubulose that is rectangle; with the protection weldering installation seat plate 5 and beam body are welded again, with the protection weldering two energy-absorbing longerons 4 and crossbeam 1 are welded into integral body at last.
In structure shown in the accompanying drawing 3,4,5, described guiding buffering hole slot 6 is perforation of opening on energy-absorbing longeron wall or the guiding that does not connect distortion hole.
The utility model adopts bolt to be fixed on the chassis side rail front end by the mounting hole of being opened 7 when mounted on installation seat plate 5; when automobile generation head-on crash; energy-absorbing longeron 4 produces plastic deformation; rationally absorb collision energy; protection driver and conductor's safety; when collision is keeped in repair later, only need turn on bolt, the utility model is changed be got final product.
