In order to transfer the collision main body, a transfer beam 2 structure is added between the vehicle body longitudinal beam and the upper longitudinal beam 1. The beam can well connect the transmission paths of the two main bodies at the front end of the vehicle body, and better decompose and absorb impact energy in a frontal impact.
The upper and lower car bodies are connected by the structure that the car body impact energy is decomposed from the transmission beam 2 to the lower longitudinal beam to the upper longitudinal beam 1. Through the actual mounting position structure of the transfer beam 2 under the whole vehicle, the welding points of the original single wheel cover structure are connected through the welding edges to form a cavity, and the structural integrity of the impact area at the front end of the vehicle is improved.
A harness via hole 21 is provided near the middle of the transfer beam 2. The first end of the transfer beam 2 is provided with a paint hole 23. The second end of the transfer beam 2 is provided with a stepped hole 22.

The first end of the longitudinal beam main body 3 is also provided with a water tank installation beam 7, and the water tank is installed on the water tank installation beam 7. The longitudinal beam main body 3, the upper longitudinal beam 1 and the transfer beam 2 are welded and connected. The method can meet the safety index of the whole vehicle and the torsional rigidity index of the front cabin area.
According to the design of the front side collision path of the whole vehicle, the lap joint relation of the wheel cover, the longitudinal beam and the upper longitudinal beam 1 is matched between the front end collision longitudinal beam area of the vehicle and the upper longitudinal beam 1 area, and the structure of the transfer beam 2 is designed, as shown in fig. 3.
The transfer beam 2 structure can effectively transfer the impact energy of the lower vehicle body longitudinal beam structure to the upper longitudinal beam 1 area, so that the upper vehicle body can participate in energy absorption at the same time, and the structural integrity is ensured, as shown in fig. 4.
In the structure of guaranteeing the original platform, the peripheral structural design transfer beam 2 is fully utilized, the transfer path is increased, and the design function definition of the platform structure is expanded, as shown in fig. 5.
The transmission structural member is connected with the peripheral member through a welding edge according to the molding requirement of the combination process, and forms a transmission path through welding the front end face with the longitudinal beam and welding the upper end face with the upper longitudinal beam 1, as shown in figure 1.
Has the following advantages:
1. the front end collision working condition index requirement of the whole vehicle is effectively integrated, and one-sided analysis and judgment on a certain front working condition can be avoided;
2. through the design of the design scheme of the transmission structure of the front end collision longitudinal beam area and the upper longitudinal beam area of the vehicle, the large-area change of the structure is avoided, and the effects of reducing the cost and improving the performance of the original platform are achieved.
3. The situation that the work is independently carried out during design is effectively reduced, and the matching period of the parts and the whole vehicle design is effectively combined in a forward moving mode.
After the structure is adopted, the impact energy of the car body is decomposed from the transmission beam to the upper longitudinal beam structure at the lower part, and the upper car body and the lower car body are connected. In order to transfer the structure of the collision main body, a transfer beam structure is added between the vehicle body longitudinal beam and the upper longitudinal beam. The beam can well connect the transmission paths of the two main bodies at the front end of the vehicle body, and better decompose and absorb impact energy in a frontal impact.
