Detailed Description
The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.
The present embodiment proposes a front wall panel assembly, as shown in fig. 1 to 3, including a front wall upper panel 9, a front wall lower panel 4 and a front wall cross beam 1, wherein two ends of the front wall cross beam 1 are welded to two front wheel covers, the front wall lower panel 4 is connected to a first front longitudinal beam 2 and a second front longitudinal beam 3, and the front wall cross beam 1 is located above the first front longitudinal beam 2 and the second front longitudinal beam 3, and is not directly connected to the first front longitudinal beam 2 and the second front longitudinal beam 3.
The front wall lower plate 4 is provided with a first reinforcing beam 5 and a second reinforcing beam 6, one end of the first reinforcing beam 5 is welded with the front wall cross beam 1, the other end of the first reinforcing beam is fixedly connected with the second front longitudinal beam 3, one end of the second reinforcing beam 6 is welded with the front wall cross beam 1, the other end of the second reinforcing beam is fixedly connected with the second front longitudinal beam 3, the first reinforcing beam 5 and the second reinforcing beam 6 are combined to form a splayed structure, and the front wall cross beam 1, the first reinforcing beam 5 and the second reinforcing beam 6 are combined to form a pi-shaped structure.
The first reinforcement beam 5 and the second reinforcement beam 6 connect the front wall cross member 1 with the first front longitudinal beam 2 and the second front longitudinal beam 3, respectively, and when a collision occurs, the impact force of the cabin parts is firstly transmitted to the front wall cross member 1, then the front wall cross member 1 transmits the impact force to the first front longitudinal beam 2 and the second front longitudinal beam 3 through the first reinforcement beam 5 and the second reinforcement beam 6, and finally the first front longitudinal beam 2 and the second front longitudinal beam 3 transmit the impact force to the rear of the vehicle. Thereby the stability of enclosing crossbeam 1 before having improved, for prior art, avoided stress concentration before enclosing crossbeam 1 on, and then enclosed crossbeam 1 and damage before leading to, the phenomenon that cabin spare part got into passenger cabin.
Because the first reinforcing beam 5 and the second reinforcing beam 6 are arranged on the cowl lower panel 4, the first reinforcing beam 5 and the second reinforcing beam 6 function as reinforcing ribs, the strength of the cowl lower panel 4 is further improved, and meanwhile, the first reinforcing beam 5 and the second reinforcing beam 6 are in a shape like a Chinese character 'ba', and compared with the existing reinforcing ribs arranged transversely or vertically, the area in which stress concentration can be avoided is larger, so that the cowl lower panel 4 has higher strength.
The first and second reinforcement beams 5,6 are U-shaped in cross-section such that the first and second reinforcement beams 5,6 each enclose a cavity 12 therebetween, wherein the transverse cross-section is a direction perpendicular to the extension of the first and second reinforcement beams 5, 6. The above structure is formed by the first and second reinforcement beams 5 and 6 protruding toward the outside.
By realizing the structure of the cavity 12, the lightweight of the front wall lower plate is optimized, the weight reduction is realized, and the cost is reduced.
