Abstract
The utility model discloses an automobile anti-bump energy absorption device, which mainly comprises a bumper cross beam and an energy absorption box. The bumper cross beam comprises a high strength outer board and an inner board with the two ends welded in a B shaped sealed cross section at the attached part. The energy absorption box comprises two groove mouth shaped box boards welded with weld seam to form a mouth shaped cross section with distortion on the attachment part, and the energy absorption box is arranged in an open manner with a symmetrical induction hole, which is beneficial to the induced crushing distortion. The front and the back are separately provided with a connection board to form a sealed device through welding to make convenient the load to be transmitted separately. Because the used sealed B shaped cross section shape is welded by the inner board and the outer board of the bumper cross beam, the utility mode has good anti-bending rigidity, the energy absorption box is welded by two gold plating pieces with guiding holes, which can more completely deform and absorb energy compared with traditional energy absorption box with guiding grooves, and the energy absorption box and the bumper cross beam are connected in the vertical direction through bolts, the taken space is small. The structure is provided with good vertical rigidity and anti-bending rigidity, and is an energy absorption device with relatively good load transmission path and simple practicality.
Description
Technical field
The utility model relates to a kind of anti-collision energy absorption device, especially relates to a kind of automobile collision preventing energy absorption device.
Background technology
Along with the continuous development of auto-industry and reaching its maturity of consumption market, the crash survivability of automobile is more and more paid attention to by people.When bumping, irrational distortion can reduce crew module's living space, serious threat occupant's safety.At present, the automobile collision preventing energy absorption device is constructed and is, mainly is made up of bumper beam and energy-absorbing box, and the bumper beam cross section mostly is simple circular arc or square-section, and the energy-absorbing box mostly is square box body, offers above and induces groove.The shortcoming of present energy absorption device is that the strength and stiffness and the energy-absorbing box of bumper beam is difficult to coupling; the loading transfer path is unreasonable; be easy to out the bumper beam distortion in hitting with post preceding bumping, energy-absorbing box energy-absorbing is insufficient, thereby influences loading transfer and to crew module's protection.
Summary of the invention
The technical problems to be solved in the utility model is, in order to remedy the weak point of existing automobile collision preventing energy absorption device, more can fully be out of shape and energy-absorbing and provide a kind of, has loading transfer path preferably, and simple and practical automobile collision preventing energy absorption device.
The utility model is to solve the problems of the technologies described above to adopt following technical scheme: the automobile collision preventing energy absorption device mainly is made up of bumper beam and energy-absorbing box.Bumper beam is welded at the two ends, joint place by outside plate and inner panel and forms " B " shape closed cross-section.The energy-absorbing box is welded into " mouth " tee section by the dislocation of two notch shape box plates at the joint place weld seam, and front and back respectively have a plate to pass through welding formation closing appliance, so that energy-absorbing is more abundant.
Good effect of the present utility model is, because the closed cross-section shape that adopts bumper beam to be welded to form " B " shape by inner panel and outside plate, device is simple, has good longitudinal rigidity and bending stiffness; The energy-absorbing box is to have aperture two sheet metal components to be welded, and induces the energy-absorbing box of groove more can fully be out of shape and energy-absorbing than traditional having, and energy-absorbing box and bumper beam are a kind of simple and practical energy absorption devices in the vertical by bolted connection.
Bumper beam device and technology are simple, are easy to assembling, and Stiffness Distribution is even, has good longitudinal rigidity and bending stiffness.When collision, the load that device transmits before effectively transmitting reduces to take advantage of crew module's distortion, thereby reaches protection occupant's purpose.This later-model anti-collision energy absorption system not only can with and head-on crash, can also use and side collision and rear impact.
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
Description of drawings
Fig. 1 is an automobile collision preventing energy absorption device organigram.
Fig. 2 is the bumper beam scheme drawing.
Fig. 3 is the bumper beam section drawing.
Fig. 4 is an energy-absorbing box block diagram.
Fig. 5 is an energy-absorbing box section drawing.
Among the figure: 1. energy-absorbing box adapter plate, 2. energy-absorbing box, 3. bumper beam outside plate 4. bumper beam inner panels 5. are connecting panel, 6. induce the hole, 7. bolt hole, the 8. first box plate, the 9. second box plate, the connecting panel of 10 energy-absorbing boxes and vehicle body, 11. welded nuts, 12. weld seams, 13. bumper/spoiler connecting panels.
The specific embodiment
Embodiment as shown in Figure 1, 2, 3, a kind of automobile collision preventing energy absorption device, mainly form by bumper beam and energy-absorbing box, " B " shape closed cross sectional structure that bumper beam is made of bumper beam outside plate 3 and 4 welding of bumper beam inner panel, two ends are connected with energy-absorbing box 2 by bolt 5.The bolt hole 7 that on bumper beam outside plate 3, connects energy-absorbing box 2 in addition.
Described energy-absorbing box 2 is welded into " mouth " tee section by two notch shapes, the first box plate 8,9 dislocation of the second box plate at joint place weld seam 12, front and back respectively have bumper/spoiler connecting panel 13, energy-absorbing box adapter plate 1 to form closing appliance by welding, and every flanging place has and induces hole 6 on the energy-absorbing box.Shown in Fig. 4,5.
Open 2 at every flanging place of energy-absorbing box and induce the hole.This energy-absorbing box device and technology are simple, and because its special conquassation induces form-perforate to induce the distortion conquassation, than the easier conquassation distortion of the general energy-absorbing box of inducing grooved, add its special welding manner-dislocation welding (weld seam 12 among Fig. 5), make it more can fully absorb energy.The aspect ratio of energy-absorbing box is generally 1.8mm, and the diameter of aperture is 13mm, and the approximate location of aperture as shown in Figure 5.Open 2 apertures (Fig. 4 mesopore 6) at every flanging place of energy-absorbing box, all close front end of aperture in front, the aperture of the back aperture in front and the midway location of rear end.This energy-absorbing box can access desirable distortion owing to be to adopt the form of perforate to induce distortion when bumping, and fully absorbs energy.And such energy-absorbing box energy-absorbing effect is not very sensitive to the thickness of sheet metal component and material, induces the effect of energy-absorbing box energy-absorbing of groove good than common having.
