The invention provides a front vehicle body structure which comprises a front upper anti-collision rod, a front girder welding piece, a front wheel cover welding piece, a front coaming reinforcing plate, an A column lower reinforcing plate and a threshold reinforcing plate welding piece, wherein the front upper anti-collision rod is connected with the front girder welding piece, the front girder welding piece is connected with the front wheel cover welding piece, the front wheel cover welding piece is connected with the front coaming reinforcing plate, the front coaming reinforcing plate is connected with the A column lower reinforcing plate, and the A column lower reinforcing plate is connected with the threshold reinforcing plate welding piece.
As a further improvement of the invention, the front girder welding piece is connected with a front girder B welding piece.
As a further improvement of the invention, the front girder welding piece is connected with a front cross beam of the front coaming, and the front cross beam of the front coaming is connected with a central channel assembly.
As a further improvement of the invention, the front girder welding piece is connected with a front baffle lower mounting plate welding piece.
As a further improvement of the invention, the front wheel cover weldment is connected with an a-pillar upper reinforcing plate.
The beneficial effects of the invention are as follows: through the scheme, the transmission path of force can be clarified through optimizing the structure, and the safety performance of the whole vehicle is improved.
Drawings
Fig. 1 is a schematic view of a front vehicle body structure of the present invention.
Detailed Description
The invention is further described with reference to the following description of the drawings and detailed description.
As shown in fig. 1, a front vehicle body structure includes a front upper bumper 3, a front girder welded part 4, a front wheel cover welded part 5, a dash panel reinforcement plate 6, an a-pillar lower reinforcement plate 7, and a threshold reinforcement plate welded part 8, wherein the front upper bumper 3 is connected with the front girder welded part 4, the front girder welded part 4 is connected with the front wheel cover welded part 5, the front wheel cover welded part 5 is connected with the dash panel reinforcement plate 6, the dash panel reinforcement plate 6 is connected with the a-pillar lower reinforcement plate 7, the a-pillar lower reinforcement plate 7 is connected with the threshold reinforcement plate welded part 8, and the front upper bumper 3, the front girder welded part 4, the front wheel cover welded part 5, the dash panel reinforcement plate 6, the a-pillar lower reinforcement plate 7, and the threshold reinforcement plate welded part 8 form a force transmission path.
As shown in fig. 1, the front girder welding member 4 is connected with a front girder B welding member 9, and the front upper bumper 3, the front girder welding member 4 and the front girder B welding member 9 form a force transmission path.
As shown in fig. 1, the front girder welding piece 4 is connected with a front panel front beam 2, the front panel front beam 2 is connected with a central channel assembly 11, and the front upper bumper 3, the front girder welding piece 4, the front panel front beam 2 and the central channel assembly 11 form a force transmission path.
As shown in fig. 1, the front girder welding piece 4 is connected with a front partition board lower mounting plate welding piece 1, and the front upper bumper 3, the front girder welding piece 4 and the front partition board lower mounting plate welding piece 1 form a force transmission path.
As shown in fig. 1, the front wheel cover welding member 5 is connected with an a-pillar upper reinforcing plate 10, and the front upper bumper beam 3, the front girder welding member 4, the front wheel cover welding member 5 and the a-pillar upper reinforcing plate 10 form a force transmission path.
According to the front vehicle body structure provided by the invention, as shown in fig. 1, the arrow in fig. 1 indicates the force transmission direction, 6 effective front collision force transmission paths are arranged on one side of a front region of a vehicle body, the left/right sides are symmetrical, the total number of the transmission paths is 12, and under the condition that the space under a floor is limited and the cross section of a longitudinal beam cannot be enlarged, the transmission paths are optimized, the central channel is strengthened to share collision force transmission, and finally the collision requirement is met. The left/right girder assembly is connected in two sections (a front girder and a rear girder) and penetrates through the front girder and the rear girder, the front girder adopts a common high-strength steel material to play a role in absorbing energy during collision according to performance requirements, the rear girder adopts a hot forming plate to play a role in resisting deformation and protecting a passenger cabin during collision, the cross sections of the two girders are different in size, thickness and span, and reasonable splitting and using different grade materials can play a good role in collision and reduce the cost of a vehicle body.
The foregoing is a further detailed description of the invention in connection with the preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the invention, and these should be considered to be within the scope of the invention.
