Specific embodiment
It is of the invention to reach the technical means and efficacy that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Attached drawing and preferred embodiment, the present invention is described in detail as follows.
It please refers to Fig.1 to Fig.3, car engine room assembly of the invention includes upper longitudinal beam 10, upper longitudinal beam channel 20, fore sub frame
Mounting rack 30, front longitudinal beam 40, energy-absorption box 50 and front anti-collision beam 60.
Wherein, the front in upper longitudinal beam channel 20 welds together with fore sub frame mounting rack 30, and rear portion and upper longitudinal beam 10 are welded
Be connected together, and with the transmitting of 40 shared power of front longitudinal beam and energy-absorbing function, play in collision process (i.e. vehicle in X direction
The length direction of body) backward power transmission and ensure 40 collapse energy-absorption of front longitudinal beam when stability effect.
Specifically, upper longitudinal beam channel 20 is made of high strength steel material (such as HC340/590DP material), by side
It sees C-shaped.As shown in figure 4, upper longitudinal beam channel 20 include inner panel 22 before outside plate 21, upper longitudinal beam channel before upper longitudinal beam channel, it is upper vertical
Inner panel 24 behind outside plate 23 and upper longitudinal beam channel behind beam channel.Outside plate 21 and inner panel 22 before upper longitudinal beam channel before upper longitudinal beam channel
Cross section is in Z-shaped, they mutually overlap and constitute upper longitudinal beam channel leading portion 25 after faying surface welding.Behind upper longitudinal beam channel
The cross section of inner panel 24 is in Z-shaped after outside plate 23 and upper longitudinal beam channel, they mutually overlap and constitute after faying surface welding
Upper longitudinal beam channel back segment 26.The height of upper longitudinal beam channel leading portion 25 is lower than the height of upper longitudinal beam channel back segment 26, leads between them
The mode for crossing welding links together, and connects in smooth arc, to facilitate preferably transmitting energy.Before upper longitudinal beam channel
After section 25 and upper longitudinal beam channel back segment 26 weld together, the inside in upper longitudinal beam channel 20 forms one by outside plate before upper longitudinal beam channel
21, before upper longitudinal beam channel behind inner panel 22, upper longitudinal beam channel behind outside plate 23 and upper longitudinal beam channel inner panel 24 surround through upper vertical
The energy-absorbing space in beam channel 20.
Further, upper longitudinal beam channel leading portion 25 (i.e. before upper longitudinal beam channel before outside plate 21 and upper longitudinal beam channel on inner panel 22)
Side be concavely provided with several crumple muscle 27 for being alternatively arranged and being substantially parallel to each other, upper longitudinal beam channel back segment 26 is (i.e. upper vertical
Inner panel 24 behind outside plate 23 and upper longitudinal beam channel behind beam channel) side be then substantially flat surface, such setting can make vertical
Beam channel leading portion 25 generates crumple deformation in collision and absorbs collision energy, and upper longitudinal beam channel back segment 26 is then resisted in collision
Displacement transfer impact force, so that solution collision present in vehicle collisions is unstable, energy-absorbing is insufficient and collision adds
The excessively high problem of speed.
In addition, as shown in Figure 1 to Figure 3, the inside of upper longitudinal beam channel leading portion 25 and fore sub frame mounting rack 30 are welded on one
It rises, and the front in upper longitudinal beam channel 20 protrudes out fore sub frame mounting rack 30 in X direction and is vacantly arranged, upper longitudinal beam channel 20 is convex
It stretches out the part of fore sub frame mounting rack 30 and energy-absorption box 50 is arranged laterally side by side and is located in the range of energy-absorption box 50, play
The effect of energy-absorbing in collision process.
Upper longitudinal beam channel back segment 26 and the leading portion of upper longitudinal beam 10 weld together, in upper longitudinal beam channel 20 and upper longitudinal beam 10
Junction has one section of overlay region, in overlay region, a part of phase mutual respect of a part and upper longitudinal beam 10 in upper longitudinal beam channel 20
It is folded, sufficiently energy-absorbing is played the role of further by the setting of overlay region.
Front longitudinal beam 40 is arranged and substantially parallel with upper longitudinal beam channel 20 in X direction laterally side by side with upper longitudinal beam channel 20.
The front end of front longitudinal beam 40 is connect with energy-absorption box 50, and the rear end of front longitudinal beam 40 is connect with upper longitudinal beam 10.Preferably, before front longitudinal beam 40
Holding with the connection type of energy-absorption box 50 is to be spirally connected, and the rear end of front longitudinal beam 40 passes through a wheel cover assembly and upper longitudinal beam 10 then with welding
Mode realizes connection.Fore sub frame mounting rack 30 is welded in the outside of 40 leading portion of front longitudinal beam.Front anti-collision beam 60 is soldered to energy-absorption box
50 front end.
When using automobile of the invention be collided when, suffered by impact force a part by front anti-collision beam 60, inhale
Energy box 50 is transferred to front longitudinal beam 40, and another part is transferred to upper longitudinal beam channel 20 and upper longitudinal beam by front anti-collision beam 60, energy-absorption box 50
10, so as to play the role of the power transmission backward in X direction in collision process by more dispersed Path of Force Transfer, and can protect
Hinder stability when longitudinal-beam crushing energy-absorbing, ensures the safety of the energy-absorbing effect and automobile of car engine room assembly of the present invention.
In addition, in the present invention, before outside plate 23, upper longitudinal beam channel behind outside plate 21, upper longitudinal beam channel before upper longitudinal beam channel
The energy-absorbing space in the upper longitudinal beam channel 20 that 24 4 components of inner panel are constituted after inner panel 22 and upper longitudinal beam channel, can also play energy-absorbing
Effect, improve the safety of automobile；Simultaneously can also be protruded out by the front end in upper longitudinal beam channel 20 fore sub frame mounting rack 30,
Topology layouts energy-absorbings in collision process such as the overlay region of upper longitudinal beam channel 20 and 10 junction of upper longitudinal beam；And can also by
Crumple muscle 27 is arranged in upper longitudinal beam channel leading portion 25, and makes in the mode that smooth side plane is arranged in upper longitudinal beam channel back segment 26 upper vertical
Beam channel leading portion 25 generates crumple in collision and receives deformation, the then resistance to deformation in collision of upper longitudinal beam channel back segment 26, from
And it solves to collide unstable, the problem that energy-absorbing is insufficient and crash acceleration is excessively high present in vehicle collisions.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
It is right according to the technical essence of the invention for the equivalent embodiment of equivalent variations, but without departing from the technical solutions of the present invention
Any simple modification, equivalent change and modification made by above embodiments, all of which are still within the scope of the technical scheme of the invention.
