The extension that can regard 3 front end of side reinforcing beam as, when central collision occurs for vehicle, branch portion 6 is one with side reinforcing beam 3 and touches
The transmission path of power is hit, main part 5 and stringer 2 are an other transmission paths for impact force, and impact force passes through this two power transmissions
Path disperses to transmit backward, and a certain position of vehicle body is avoided to concentrate stress, Reducing distortion amount.In addition, if side impact and not occurs for vehicle
In the case where direct collision main part 5, thus energy-absorbing deformation can be carried out by the related main part 5 of branch portion 6.By the way that branch portion is arranged
6 can effectively promote the intensity and collision performance of front end endergonic structure, without developing front end endergonic structure again, save
Cost and time.
As depicted in figs. 1 and 2, body structure further includes mounting plate 7, and the front end of main part 5 and front anti-collision beam 1 weld, main
The rear end in body portion 5 and mounting plate 7 weld, and the rear end of the front end of stringer 2, the front end of side reinforcing beam 3 and branch portion 6 is with before
End casing 4 welds, and mounting plate 7 is bolted with cover board of front end 4.
Specifically, the front end of main part 5 and front anti-collision beam 1 weld, and the rear end of main part 5 and mounting plate 7 weld, stringer 2
Front end and the front end of side reinforcing beam 3 welded with cover board of front end 4, mounting plate 7 is bolted with cover board of front end 4, branch portion 6
It is welded respectively with main part 5 and cover board of front end 4.In assembly, first the front end of main part 5 and the end of front anti-collision beam 1 are welded
Together, then, the rear end of main part 5 and mounting plate 7 are welded together, then welds branch portion 6 and main part 5, then
The front end of stringer 2 and the front end of side reinforcing beam 3 are welded together with cover board of front end 4, in cover board of front end 4 and mounting plate 7 all
It is formed with bolt hole, is then fixed together cover board of front end 4 and mounting plate 7 by bolt, finally by 6 front end of branch portion
Cover board 4 welds together.It is attached by way of above-mentioned welding and bolt, connection is reliable, dismounting, easy to maintenance, raising
Installation accuracy and assembly convenience, improve the working efficiency of staff.
As an alternative embodiment, as shown in Figures 3 to 5, main part 5 and branch portion 6 can be separate structure,
Branch portion 6 is connected with main part 5 and cover board of front end 4 respectively.
Branch portion 6 can be in U-shape structure, and including the upper surface of being oppositely arranged plate 61 and lower panel 62 and being formed in
Side plate 63 between panel 61 and lower panel 62, top panel 61 are connected on the upper surface of main part 5, and lower panel 62 is connected to master
On the lower surface in body portion 5, the rear end of top panel 61 is formed with the first flange 611, and the rear end of lower panel 62 is formed with the second flange
621, the rear end of side plate 63 is formed with third flange 631, and the first flange 611, the second flange 621 and third flange 631 are connected to
In cover board of front end 4.Top panel 61 and lower panel 62 can be separately fixed at the upper and lower surface of main part 5 by welding
On, the first flange 611, the second flange 621 and third flange 631 can also be fixedly connected on drive end bearing bracket by welding
On plate 4,5 three stringer 2, side reinforcing beam 3 and main part cavitys are linked together by this branch portion 6, increase this three
Bonding strength between a cavity.
In addition, top panel 61 and lower panel 62 can be in a rectangular trapezoid and horizontally extending, between cathetus edges
Be formed with the side plate 63 extended along the vertical direction, the angle of side plate 63 and cover board of front end 4 between 30 degree to 60 degree so that its
The transverse direction of vehicle body has a degree of extension, can be considered as front anti-collision beam 1 in lateral extension, the small overlapping area in front is occurring
When collision, effective energy-absorbing function is played.There are also some needs to make an explanation, for example, when the left side of front anti-collision beam 1 occurs
When collision (side collision), under the transmitting effect of power, the connection welding between the main part 5 and mounting plate 7 on right side is often
The case where tearing, and in the disclosure, branch portion 6 is welded on the main part 5 on right side and cover board of front end 4, right side
Branch portion 6 can be considered as a reinforcement rib structure, and the connection welding between the main part 5 and mounting plate 7 on right side is effectively protected,
It avoids there is a situation where tearing, in addition, the branch portion 6 on right side can also drive the side reinforcing beam 3 on right side to participate in deformation energy-absorbing, increases
The transmission path of reinforcing, energy-absorbing effect is more preferably.
In addition, as shown in Figures 3 to 5, the first crumple endergonic structure 8, side plate are formed on top panel 61 and lower panel 62
It is formed with the second crumple endergonic structure 9 on 63, the first crumple endergonic structure 8 includes tri-angle-holed 81 and oblong hole 82, and second
Crumple endergonic structure 9 includes a plurality of flute profile energy-absorbing muscle extended along bodywork height direction, the energy-absorbing hole of triangle and slotted hole shape
Structure constitutes joint endergonic structure with a plurality of flute profile energy-absorbing muscle, and energy-absorbing effect is more preferable.When a vehicle is in a collision, the first crumple is inhaled
Energy structure 8 and 9 collective effect of the second crumple endergonic structure, can absorb the energy from collision, it is thus possible to avoid in large quantities
Impact energy all passes to stringer 2 and side reinforcing beam 3, so as to alleviate the deformation journey of stringer 2 and side reinforcing beam 3
Degree, but also the impact energy for being transferred to crew module and cabin can be reduced.
In the disclosure, main part 5 and branch portion 6 can be integrally formed, and while guaranteeing structural strength, avoid increasing more
Remaining connection structure saves cost.
The disclosure also provides a kind of vehicle, including above-mentioned body structure.
The preferred embodiment of the disclosure is described in detail in conjunction with attached drawing above, still, the disclosure is not limited to above-mentioned reality
The detail in mode is applied, in the range of the technology design of the disclosure, a variety of letters can be carried out to the technical solution of the disclosure
Monotropic type, these simple variants belong to the protection scope of the disclosure.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case where shield, can be combined in any appropriate way, in order to avoid unnecessary repetition, the disclosure to it is various can
No further explanation will be given for the combination of energy.
In addition, any combination can also be carried out between a variety of different embodiments of the disclosure, as long as it is without prejudice to originally
Disclosed thought equally should be considered as disclosure disclosure of that.
