Longeron 5, then A columns 11, right side A columns 12 and front windshield bottom end rail 8 transmit to the left, and pass through left side A columns 11 and right side A columns 12
It is transmitted to front wall crossbeam 9, front wall crossbeam 9 is passed by the left longeron 13 of middle channel and middle channel right vertical beam 14 to seat front beam 10
Power.
It is energy-absorption box and front longitudinal beam (left front girder 2 and front right longitudinal beam 3) front end collapse energy-absorption, preceding in 40% offset collision
Longeron (left front girder 2 and front right longitudinal beam 3) root is in Y-direction (vehicle width direction) bending energy-absorbing, upper longitudinal beam (upper left longeron 4 and upper right
Longeron 5) in Z-direction (vertical direction) bending (being crushed during the front boom long enough of upper left longeron 4 and upper right longeron 5), gooseneck
Structure (left gooseneck structure 201 and right gooseneck structure 301) allows to have slight deformation but mainly plays intermal force, front anti-collision beam 1 and
Front wall crossbeam 9 will can also be transferred to power on cabin opposite side stress frame in self-deformation energy-absorbing.Fig. 3 is shown
The Path of Force Transfer of the 40% offset collision constantly front deck force transferring structure, compared with Fig. 2, longitudinal power transmitting is identical, laterally
The lateral opposite side power transmission that impact force is then impacted by power transmission by front anti-collision beam 1, front windshield bottom end rail 8 and front wall crossbeam 9.
During 25% head-on crash, optimization upper longitudinal beam (upper left longeron 4 and upper right longeron 5) is with 1 connection structure of front anti-collision beam
It can.Upper longitudinal beam (upper left longeron 4 and upper right longeron 5) and front longitudinal beam (left front girder 2 and the right side can effectively ensure that by front anti-collision beam 1
Front longitudinal beam 3) connection, play the role of power transmission.
The front end of the front deck force transferring structure of the utility model embodiment, the middle left longeron of channel and middle channel right vertical beam is connected to
On front wall crossbeam, the rear end of the middle left longeron of channel and middle channel right vertical beam is connected on seat front beam, left gooseneck connecting plate edge
