Individual energy-absorption box 23 is connected with automobile skeleton 30, and each energy-absorption box 23 is connected with a connecting plate 24 respectively.At the present embodiment one
In individual schematic scheme, one end of each energy-absorption box 23 is all welded with the positive portion 211 of front anticollision beam assembly 20, and each energy-absorbing
The other end of box 23 and a connecting plate 24 weld, and last connecting plate 24 is threaded connection with automobile skeleton 30.
Owing to front anti-collision beam, energy-absorption box 23, connecting plate 24 are aluminium alloy extrusions part, by using first by these multiple portions
Part is by being welded to connect in one, the mode threadeded with automobile skeleton 30 the most again, convenient transportation, it is simple to detachable maintaining.
Alternatively, owing to, in the front impact from headstock direction, head-on crash power is touched more than anterior side surface direction
Hitting power, in order to increase the collision performance of front anti-collision beam further, the positive portion 211 of the front anti-collision beam in the present embodiment is also associated with
Crashproof buttress brace 22.This crashproof buttress brace 22 is arranged along vehicle-body width direction D2, and fixing with the front side in positive portion 211 is connected, use
In the anticollision performance strengthening positive portion 211.
It addition, the front anti-collision beam in the present embodiment is only additionally arranged crashproof buttress brace 22 in positive portion 211, rather than whole crashproof
All set up buttress brace on girder 21, not only ensure that the collision performance of front anti-collision beam, and be capable of reducing front anti-collision beam
The purpose of weight, it is achieved that the lightweight of front anti-collision beam.
Wherein, crashproof buttress brace 22 has multiple with the connected mode in positive portion 211, such as welding, threaded etc., the present embodiment
In preferred crashproof buttress brace 22 with positive portion 211 for welding, be connected firmly, convenient.
It has been observed that front anti-collision beam distance ground is in the range of 438mm～498mm, the crashproof buttress brace 22 in the present embodiment
Distance ground level scope is 438mm～478mm, belongs to optimum collision region.
Therefore, the front anticollision beam assembly 20 in the present embodiment uses aluminium alloy extrusions to shape, and weight is 3kg.And pass
The front anticollision beam of automobile assembly of the steel material of system, weight is 7.5kg, is formed according to welding, complex process.Aluminum alloy materials
Front anticollision beam assembly 20 loss of weight more than 50%, weight loss effect is obvious, and technique is simple, is suitable for being applied on new-energy automobile.
Further, the crashproof girder 21 of front anticollision beam assembly 20 of the present utility model is by energy-absorption box 23 with automobile skeleton 30 even
Connecing, can absorb more impact force when collision, thus the front anti-collision beam allowing aluminium alloy to shape is ensureing stiffness
