Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, the noun of locality used is if " upper and lower, left and right " are normally for the direction of accompanying drawing, " forward and backward " is then the direction that normally moves forward with vehicle for benchmark defines, the length direction of the vehicle that " Width " extends perpendicular to front and back.
As shown in Figures 1 to 4, the invention provides a kind of rear bumper energy absorption device of vehicle and use the vehicle of this energy absorption device, wherein rear bumper energy absorption device comprises energy absorbent block body 5, described energy absorbent block body 5 is fixedly mounted in rear bumper frame body 1, and between this rear bumper frame body 1 and back wall panel beating 4.
Therefore; by installing energy absorbent block body 5 in rear bumper frame body 1; after Impactor 2 collides rear bumper frame body 1; when continuing invasion; first contact with energy absorbent block body 5, energy absorbent block body 5 by conquassation, absorbs the collision energy of Impactor 2 by self; stop Impactor 2 by energy transferring to back wall panel beating 4 structure, to reach the object of protection back wall panel beating.
In addition, because between rear bumper frame body 1 and back wall panel beating 4, the fore-and-aft distance of vehicle is limited, so, as one preferably embodiment, energy absorbent block body 5 provided by the present invention extends along the Width of vehicle, can make full use of longitudinal space limited between rear bumper frame body 1 and back wall panel beating 4 and relatively long width spaces.
Particularly, as one preferably embodiment, as shown in Figure 2, energy absorbent block body 5 provided by the invention, this energy absorbent block body 5 comprises peripheral board 6 and multiple dividing plate 7, and the plurality of dividing plate 7 is positioned at described peripheral board 6 inside and is that criss-cross is to form multiple energy-absorbing hole 8 mutually.Owing to defining the cancellated energy-absorbing hole 8 of multiple formation, by the effect each other of adjacent energy-absorbing hole 8, add energy-absorbing effect greatly.Therefore, energy absorbent block 5 is by the distortion in inner multiple energy-absorbing hole 8, and absorb the collision energy of Impactor 2, the collision energy of collision free block 2 is directly passed to back wall panel beating 4, to reach the object of protection back wall panel beating 4.Particularly, as shown in figures 1 and 3, dividing plate 7 is vertically arranged, to make formed multiple energy-absorbing holes 8 upper and lower opening and vertically to extend, to absorb collision energy from back to front better.
More specifically, described peripheral board 6 comprises header board 61, rear plate 62, left side board 63 and right side board 64, described header board 61 contacts or near described back wall panel beating 4, described rear plate 62 abuts in described rear bumper frame body 1, thus surrounds the space holding energy-absorbing hole 8.In other embodiments, also such as can not arrange the distortion of the modes such as left side plate, the present invention does not limit this.
In addition, conveniently energy absorbent block body 5 is fixedly mounted in rear bumper frame body 1, and as one preferably embodiment, described energy absorbent block body 5 also comprises connecting portion 9, this connecting portion 9 is formed on described dividing plate 7, and is fixed in described rear bumper frame body 1.Therefore, in this way, can easily energy absorbent block body 5 be fixedly mounted in rear bumper frame body 1 by connecting portion 9.
Particularly, as another kind preferably embodiment, described connecting portion 9 is formed with blocked hole 91, to snap fit onto in described rear bumper frame body 1.Therefore, in this way, described energy absorbent block body 5 can firmly snap fit onto in described rear bumper frame body 1.More specifically, as shown in Figure 4, connecting portion 9 can be formed by the part that dividing plate 7 is protruding upward.Rear bumper frame body 1 is provided with card adapter plate 92, this card adapter plate 92 is connected in rear bumper frame body 1 by modes such as welding, described card adapter plate 92 can be inserted in described blocked hole 91 and realize clamping connection to be cooperatively interacted by the two, be fixedly mounted in described rear bumper frame body 1 to make described energy absorbent block body 5, more firmly be fixedly mounted in rear bumper frame body 1 in order to energy absorbent block body 5 can be made, more specifically, described connecting portion 9 can also be welded in described rear bumper frame body 1.Therefore, by welding and the connection mode of clamping, can more described energy absorbent block body 5 be fixed in described rear bumper frame body 1.
The above-mentioned welding introduced the preferred embodiment for the present invention and provide is connected with clamping; in other implementations; energy absorbent block body 5 can also adopt other connection modes; such as; bolt connection etc.; in addition except welding, clamping, bolt connect, other the connection mode that those skilled in the art can expect also should drop in protection scope of the present invention.
In addition, as another kind preferably embodiment, described energy absorbent block body 5 is made into integration by thermoplastic material, because thermoplastic material has the characteristic of thermoplastic, hardening by cooling, therefore the energy absorbent block body 5 utilizing this material to make can reuse, economize on resources, avoid unnecessary waste.In other embodiments, energy absorbent block body 5 can also such as aluminum alloy etc. other can by the plastic material of the energy-absorbing by conquassation, the present invention does not limit this.
In addition, according to another object of the present invention, provide a kind of vehicle, this vehicle uses the rear bumper energy absorption device of vehicle provided by the invention.
Preferably, be also provided with collision prevention girders 3 below described energy absorbent block body 5, this collision prevention girders 3 extends along the Width of vehicle equally, relaxes extraneous impulsive force absorbing, and also can play the effect of protection back wall panel beating 4.
Therefore; when rear bumper frame body 1 is collided block 2 collision impact; first collision impact energy contacts with energy absorbent block body 5; after energy absorbent block body 5 is collided and impacts; self is compressed; absorb the collision impact energy on Impactor 2, with stop Impactor 2 directly by energy transferring to back wall panel beating 4, to reach the object of protection back wall panel beating 4.
To sum up, the rear bumper energy absorption device of vehicle provided by the invention, by installing energy absorbent block in rear bumper frame body, makes energy absorbent block body first absorb the energy of collision impact, protects back wall panel beating widely.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
