Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
In describing the invention, it will be appreciated that, term " " center ", " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the present invention for convenience of description and simplified characterization, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore limitation of the present invention can not be interpreted as.
With reference to Fig. 1-2, the collision energy-absorbing device that the embodiment of the present invention provides specifically comprises outer tube 13, energy absorbing tube 14 and front cross rail 15; This outer tube 13 is fixed in car body longeron 11, and energy absorbing tube 14 is removably mounted on the inside of outer tube 13, and front cross rail 15 is connected to energy absorbing tube 14 front end, plays the effect of protection energy absorbing tube 14.
Concrete, this energy absorbing tube 14 is connected to the inside of outer tube 13 by set pin 31.It should be noted that, outer tube 13 and energy absorbing tube 14 removably connect to comprise but do not limit to and adopt set pin to be connected, also can adopt bolt, screw or other can realize dismantle connect mode.
Energy absorbing tube 14 deformable is set, absorbs colliding forces by the deformation of energy absorbing tube.This energy absorbing tube 14 is in the process of colliding, absorption collision energy is carried out by there is crumple distortion in the front portion of this energy absorbing tube 14, maximum reduction impact force collision miscellaneous part or personnel, make the safety performance of car body be promoted, reduce motor traffic accidents casualty rate.Absorbing collision energy preferably to have good deformation performance, preferably, selecting steel material to make this energy absorbing tube 14.It should be noted that, the material of this energy absorbing tube 14 is not limited to steel material, and other metallic materials are applicable equally.
For the ease of being cut away in the region that energy absorbing tube 14 has occurred for crumple and distortion, this energy absorbing tube 14 arranges several groovings 141 along its length, and the quantity of this grooving 141 can be determined according to the length of energy absorbing tube 14.With reference to figure 3.
With reference to figure 4-Fig. 6, in the middle of the process of colliding, there is crumple distortion and absorb collision energy in the front portion of energy absorbing tube 14, after an impact, untie set pin 31, energy absorbing tube 14 can be pulled out a segment distance from outer tube 13, and again adopt set pin 31 energy absorbing tube 14 to be fixed on the inside of outer tube 13.Simultaneously, energy absorbing tube 14 upper forepart conquassation district 41 can be excised along grooving 141, then front cross rail 15 is reinstalled, and then can guarantee that this collision energy-absorbing device can be reused, and energy absorbing tube 14 can repeatedly recycle, and so farthest reduces maintenance cost and time, due to the great impact force of energy absorbing tube 14 Absorbable rod, therefore, the present embodiment collision energy-absorbing device can effectively reduce motor traffic accidents casualty rate, reduces automotive servicing cost simultaneously.
In addition, the embodiment of the present invention also provides a kind of car body, comprises the collision energy-absorbing device in above-described embodiment.There is the car body of this collision energy-absorbing device, can effectively reduce motor traffic accidents casualty rate, improve car body safety performance, reduce automotive servicing cost simultaneously.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
