Before being weldingly fixed on the upper end of both right A column assemblies 3 on gutter channel assembly 1；Both left A column assembly 11 and right A column assembly 3
Lower end between be provided with sequentially connected left front girder side girders 9, channel assembly 8 and front right longitudinal beam side girders 7 in front wall, it is left
The free end of 7 the two of front longitudinal beam side girders 9 and front right longitudinal beam side girders is solid with left A column assembly 11 and the welding of right A column assembly 3 respectively
It is fixed.
Secondly, left front girder and front right longitudinal beam are connected in left front girder side girders 9 and front right longitudinal beam side girders 7,
The front end of 4 the two of left front girder leading portion assembly 12 and front right longitudinal beam leading portion assembly is welded and fixed with front anti-collision beam；Left front girder
The rear end of 5 the two of back segment assembly 10 and front right longitudinal beam back segment assembly is welded and fixed with left A column assembly 11 and right A column assembly 3 respectively.
Finally, front panel crossbeam 6 from left to right successively with channel assembly 8 in left A column assembly 11, left front girder, front wall, right
Front longitudinal beam and right A column assembly 3 are welded and fixed；In front wall the both ends of riser 2 respectively with preceding gutter channel assembly 1 and front panel crossbeam 6
It is welded and fixed.Wherein, riser 2 is enclosed first in preceding gutter channel assembly 1, left A column assembly 11, front panel crossbeam 6 and front wall
Cyclic structure is 1.；Riser 2 is enclosed the second ring-type in preceding gutter channel assembly 1, right A column assembly 3, front panel crossbeam 6 and front wall
Structure is 2.；Second mounting portion 63, right A column assembly 3, front right longitudinal beam side girders 7 and front right longitudinal beam are enclosed third cyclic structure
③；Channel assembly 8 is enclosed fourth annular in front panel cross-beam body 61, front right longitudinal beam, front right longitudinal beam side girders 7 and front wall
Structure is 4.；Channel assembly 8 is enclosed the 5th in front panel cross-beam body 61, left front girder, left front girder side girders 9 and front wall
Cyclic structure is 5.；First mounting portion 62, left front girder, left front girder side girders 9 and left A column assembly 11 are enclosed the 6th ring-type
Structure is 6..Wherein, cyclic structure includes but is not limited to circular or close annular shape or triangular shape or nearly triangular shape or other are polygon
Shape and structure.
By forming multiple annular enclosed structures in front wall assembly, dispersion collision can be effectively transmitted in collision process
Power reduces the invasion amount and acceleration of front wall assembly in collision, improves collision performance, security performance and stability；And it is multiple
Annular enclosed close structure connection, not only increases the local stiffness and intensity of vehicle body, has also effectively added the rigid of vehicle body entirety
Degree and intensity.
The present invention also provides a kind of automobile, automobile includes such as above-mentioned front wall assembly.It is formed in the front wall assembly of automobile more
A closed cyclic structure can effectively transmit dispersion impact force in collision process, reduce the invasion of front wall assembly in collision
Amount, improves collision performance and security performance, moreover it is possible to promote the overall stiffness of front wall assembly and vehicle body.
From the description above with practice it is found that front wall assembly provided by the invention and including its automobile, with the prior art
It compares, has the advantage that first, front panel crossbeam is successively and before channel assembly, the right side in left A column assembly, left front girder, front wall
Before stringer is connected with right A column assembly, forms multiple annular enclosed structures in front wall assembly, and multiple annular enclosed structures pass through
Coaming plate crossbeam closely connects, and guarantees the continuity of load transfer path, is connected with each other to transmit dispersing impact forces, avoids impact force
It is mutated or interrupts in transmittance process, load is farthest distributed to other regions of car body, reduce front wall assembly in collision
Invasion amount and acceleration further promote vehicle body collision performance, security performance and stability, moreover it is possible to improve front wall assembly and vehicle body
Overall stiffness.Second, riser in front wall, the rigidity in channel in raising are added between front panel crossbeam and preceding gutter channel assembly
And stability；Reasonable distribution distributes layout of the cyclic structure in front wall assembly, to further increase the stability of front wall assembly
And intensity, reduce the intrusion volume and acceleration of front wall assembly when hitting.
It should be understood by those ordinary skilled in the art that: the above is only a specific embodiment of the present invention, and
It is not used in the limitation present invention, all any modification, equivalent substitution, improvement and etc. within purport of the invention, done should all include
Within protection scope of the present invention.
