[0040] Below reference Figures 1-6 The front wallboard structure 10 according to the embodiments of the utility model is described.
[0041] As Figures 1-6 Indicated, according to the front wallboard structure 10 of the embodiments of the utility model for vehicle and include: front wallboard body 1 and front reinforcement plate 2.
[0042] Specifically, reference Figures 1-3 The front end of the front reinforcement plate 2 is connected to the lower end of the front wallboard body 1, and the front reinforcement plate 2 includes a body plate 21, and the front end of the body plate 21 has a first protrusion 211 extending in the left-right direction of the vehicle. Wherein, in the front-to-back direction, the front reinforcement plate 2 extends downwardly.
[0043] It can be understood that the front reinforcement plate 2 and the front wallboard body 1 are stacked and connected in the thickness direction of the front wallboard body 1, wherein the front reinforcement plate 2 is arranged close to the vehicle cabin relative to the front wallboard body 1, and when the front part of the vehicle is impacted, the impact force is first transmitted to the front wallboard body 1 and then to the front reinforcement plate 2. By providing the first protrusion 211 extending in the left-right direction of the vehicle at the front end of the body plate 21, the first protrusion 211 protrudes towards the front side and downwardly, so that the body plate 21 forms a crush zone at the first protrusion 211. When the front impact force is transmitted to the body plate 21, the first protrusion 211 is first deformed by force due to its position on the front side of the body plate 21, thereby absorbing the impact force and effectively reducing the intrusion amount of the front wallboard structure 10 and improving the crash performance.
[0044] At the same time, by providing the first protrusion 211 extending in the left-right direction of the vehicle at the front end of the body plate 21, the material of the front wallboard structure 10 does not need to be changed, and the overall thickness of the front wallboard structure 10 does not need to be increased, thereby saving costs, making the front wallboard structure 10 simple to form, reducing production difficulty and improving production efficiency.
[0045] According to the front wall plate structure 10 of the embodiment of the utility model, the lower end of the front end of the front reinforcing plate 2 is connected to the front wall plate body 1, the front reinforcing plate 2 comprises a body plate 21, the front end of the body plate 21 is provided with a first protrusion 211 extending along the left-right direction of the vehicle, when the front side impact force is transmitted to the body plate 21, the first protrusion 211 is first stressed and crushed and deformed, thereby absorbing the impact force, thereby effectively reducing the intrusion amount of the front wall plate structure 10, improving the crash performance, and without changing the material of the front wall plate structure 10, also without increasing the overall thickness of the front wall plate structure 10, saving the cost, making the front wall plate structure 10 simple to form, reducing the production difficulty, and improving the production efficiency.
[0046] In some embodiments of the utility model, as shown in Figures 1-3 The front reinforcing plate 2 further comprises an extension plate 22, one end of the extension plate 22 is connected to the front end of the body plate 21, the other end extends upward, the extension plate 22 is located at the rear side of the front wall plate body 1, and the front end part of the extension plate 22 and the body plate 21 are both stacked with the front wall plate body 1 and are welded and connected.
[0047] The front end part of the extension plate 22 and the body plate 21 are both stacked with the front wall plate body 1, which can increase the contact area between the front end part of the extension plate 22 and the body plate 21 and the front wall plate body 1, thereby improving the connection reliability between the front end part of the extension plate 22 and the body plate 21 and the front wall plate body 1 stacked, thereby further improving the overall rigidity of the front wall plate structure 10 and improving the crash performance.
[0048] It can be understood that, since the extension plate 22 extends upward and is stacked with and connected to the front wall plate body 1, the extension plate 22 can be connected to the front wall plate body 1 in the front-rear direction, since the body plate 21 extends in the front-rear direction, the front end part of the body plate 21 is stacked with and welded to the front wall plate body 1, so that the front end part of the body plate 21 can be connected to the front wall plate body 1 in the up-down direction, thereby making the front reinforcing plate 2 and the front wall plate body 1 be connected in the front-rear up-down direction, thereby improving the connection reliability between the front wall plate body 1 and the front reinforcing plate 2, thereby further improving the overall rigidity of the front wall plate structure 10 and improving the crash performance.
[0049] In some embodiments of the utility model, as shown in Figures 1-3 The front wall plate structure 10 further comprises a reinforcing plate cross beam 3, the reinforcing plate cross beam 3 is arranged at the front side of the front wall plate body 1, the reinforcing plate cross beam 3 extends along the left-right direction, the upper and lower ends of the reinforcing plate cross beam 3 are both connected to the front wall plate body 1, and a cavity 31 extending along the left-right direction is formed between the reinforcing plate cross beam 3 and the front wall plate body 1.
[0050] It can be understood that the part between the upper and lower ends of the reinforcing plate cross beam 3 is spaced apart from the front wall plate body 1, thereby forming a cavity 31 extending in the left-right direction, which is arranged on the front side of the front wall plate body 1. The arrangement of the cavity 31 increases the cross-sectional size between the reinforcing plate cross beam 3 and the front wall plate body 1, thereby further improving the structural strength and improving the crash performance. At the same time, due to the arrangement of the cavity 31, when the front part of the vehicle collides, the reinforcing plate cross beam 3 can collapse and deform at the cavity 31 to absorb the collision energy, thereby further improving the crash performance.
[0051] In some embodiments of the present application, as shown in Figures 1-3 The upper end of the reinforcing plate cross beam 3 has a flange 32 extending upwardly and downwardly, and the flange 32 is arranged in layers with the front wall plate body 1 and is connected. The lower end of the reinforcing plate cross beam 3 is arranged in layers with the front wall plate body 1 and the front end portion of the body plate 21 and is connected.
[0052] It can be understood that the flange 32 is arranged in layers with the front wall plate body 1 and is connected, thereby increasing the connection area between the flange 32 and the front wall plate body 1, thereby improving the connection reliability of the flange 32 and the front wall plate body 1, and simultaneously connecting the flange 32 and the front wall plate body 1 in the front-rear direction. The lower end of the reinforcing plate cross beam 3 is arranged in layers with the front wall plate body 1 and the front end portion of the body plate 21 and is connected, thereby increasing the connection area between the lower end of the reinforcing plate cross beam 3 and the front wall plate body 1, thereby improving the connection reliability between the lower end of the reinforcing plate cross beam 3 and the front wall plate body 1, and simultaneously connecting the lower end of the reinforcing plate cross beam 3 and the front wall plate body 1 in the up-down direction.
[0053] Therefore, by arranging the flange 32 in layers with the front wall plate body 1 and connecting the flange 32, the lower end of the reinforcing plate cross beam 3 is arranged in layers with the front wall plate body 1 and the front end portion of the body plate 21 and is connected, so that the reinforcing plate cross beam 3 can be connected with the front wall plate body 1 in the up-down direction and can be connected with the front wall plate body 1 in the front-rear direction, thereby improving the connection reliability between the reinforcing plate cross beam 3 and the front wall plate body 1, thereby further improving the overall stiffness of the front wall plate structure 10 and improving the crash performance.

It can be understood that the connecting plate 121 is bent and extended rearwardly, thereby facilitating the formation of the area for the user to step on and facilitating the installation of the front reinforcing plate 2.
[0055] In some embodiments of the utility model, as shown in Figures 1-4 The body plate 21 has a second protrusion 212 protruding upward, and the second protrusion 212 extends to the rear end of the body plate 21. The lower side of the body plate 21 has a groove 213 corresponding to the position of the second protrusion 212. The first protrusion 211 is arranged on the second protrusion 212 and protrudes downward.
[0056] It can be understood that the second protrusion 212 increases the structural strength of the front reinforcement plate 2. From front to back, the second protrusion 212 is inclined downward, and the first protrusion 211 is arranged on the second protrusion 212 and protrudes downward, thereby further improving the structural strength of the front reinforcement plate 2 and improving the crash performance.
[0057] In addition, the second protrusion 212 is formed by stamping the body plate 21, so that the lower side of the body plate 21 has a groove 213 corresponding to the position of the second protrusion 212. The stamping process is fast and convenient, and no additional structure needs to be connected to the body plate 21 to form the second protrusion 212. It is low in cost and also conducive to the lightweight of the body plate 21.
[0058] In some embodiments of the utility model, as shown in Figures 1-5 The vehicle includes a front longitudinal beam rear plate 20 arranged on the lower side of the connecting plate 121 and connected with the connecting plate 121. The front longitudinal beam rear plate 20 is located on one side of the gap 122 along the left-right direction. The front wall plate structure 10 further includes a sub-frame mounting reinforcement plate 4 arranged on the lower side of the connecting plate 121. One end of the sub-frame mounting reinforcement plate 4 is connected with the front longitudinal beam rear plate 20, and the other end is connected with the same side inner wall of the groove 213 through the gap 122.
[0059] The front longitudinal beam rear plate 20 is connected with the connecting plate 121, thereby realizing the connection of the front longitudinal beam rear plate 20 and the front wall plate structure 10, further improving the integrity of the internal structure of the vehicle, reducing the deformation of the front wall plate structure 10, and improving the crash performance.
[0060] It can be understood that the gap 122 is arranged, thereby facilitating the connection of the sub-frame mounting reinforcement plate 4 and the same side inner wall of the groove 213. Through the connection of the sub-frame mounting reinforcement plate 4 and the same side inner wall of the groove 213, the connection of the sub-frame mounting reinforcement plate 4 and the front reinforcement plate 2 is realized, thereby further improving the integrity of the internal structure of the vehicle, effectively improving the dynamic stiffness of the sub-frame mounting point, and improving the crash performance.
[0061] In some embodiments of the utility model, as shown in Figures 1-5As shown, the front longitudinal beam rear plates 20 are two and are respectively arranged on the left and right sides of the notch 122, the subframe mounting reinforcement plates 4 are two, and the two subframe mounting reinforcement plates 4 are respectively arranged on the left and right sides of the notch 122, and the two subframe mounting reinforcement plates 4 correspond to the two front longitudinal beam rear plates 20 one by one.
[0062] It can be understood that the two front longitudinal beam rear plates 20 are connected with the connecting plate 121, and the two subframe mounting reinforcement plates 4 are respectively connected with the inner walls of the grooves 213, so that the integrity of the internal structure of the vehicle is further improved, the dynamic stiffness of the subframe mounting point can be effectively improved, and the crash performance is improved.
[0063] In some embodiments of the utility model, as shown in Figures 1-4 As shown, the front wall plate structure 10 further comprises: a bottom reinforcement plate 5, the left and right sides of the second protrusion 212 are respectively provided with the bottom reinforcement plate 5, one end of the bottom reinforcement plate 5 is connected with the end of the body plate 21 in the left-right direction, and the other end is connected with the side wall of the second protrusion 212.
[0064] It can be understood that the bottom reinforcement plate 5 is arranged, so that the left and right sides of the second protrusion 212 can be connected with the end of the body plate 21 in the left-right direction, thereby improving the structural stability and reliability of the second protrusion 212, reducing the crushing deformation of the second protrusion 212, and further improving the crash performance.
[0065] In addition, as shown in Figure 1 、 Figure 4 and Figure 5 The vehicle comprises front longitudinal beam rear plates 20, the front longitudinal beam rear plates 20 are arranged on the lower side of the connecting plate 121 and connected with the connecting plate 121, the front longitudinal beam rear plates 20 are located on one side of the notch 122 in the left-right direction, and the front wall plate structure 10 further comprises: subframe mounting reinforcement plates 4, the subframe mounting reinforcement plates 4 are arranged on the lower side of the connecting plate 121, one end of the subframe mounting reinforcement plates 4 is connected with the front longitudinal beam rear plates 20, and the other end is connected with the same side inner wall of the groove 213 through the notch 122.
[0066] Due to the existence of the bottom reinforcement plate 5, the subframe mounting reinforcement plate 4 can avoid lifting the connecting plate 121 during the collision process, so that the foot intrusion amount is increased, and the crash performance is further improved.
[0067] In some embodiments of the utility model, as shown in Figure 1 、 Figure 4 and Figure 5 The end of the bottom reinforcement plate 5 connected with the side wall of the second protrusion 212 extends upwardly and obliquely, and the bottom reinforcement plate 5 and the front reinforcement plate 2 define a cavity 31.
[0068] It can be understood that the cavity 31 is arranged, which increases the cross-sectional size of the structure, thereby further reducing the deformation of the second protrusion 212, and further reducing the lifting of the connecting plate 121 by the auxiliary frame mounting reinforcing plate 4, in addition, through the arrangement of the above-mentioned mode, the cross section of the cavity 31 is triangular, and the triangular cross section makes the structure of the cavity 31 more stable, thereby further reducing the deformation of the front reinforcing plate 2, thereby further improving the crash performance.
[0069] In some embodiments of the utility model, as shown in Figure 1 and Figure 6 The first plate 11 is provided with mounting plates 111 at both ends in the left-right direction, and the two mounting plates 111 are respectively adapted to be connected with two A-pillars 30 of the vehicle. It can be understood that the mounting plate 111 has a plurality of rows of mounting holes, and the plurality of rows of mounting holes are arranged in the left-right direction, and each row of mounting holes includes a plurality of mounting holes arranged in the up-down direction, thereby improving the connection reliability of the mounting plate 111 with the A-pillar 30 and the first plate 11, preventing the front wall plate structure 10 from tearing the A-pillar 30 in the small offset collision process, and further improving the crash performance.
[0070] In some embodiments of the utility model, as shown in Figure 1 and Figure 6 The first plate 11 and the second plate 12 are separate processing parts. It can be understood that the first plate 11 and the second plate 12 both have left and right side areas, wherein the front reinforcing plate 2 divides the first plate 11 and the second plate 12 into left and right side areas, the left side area of the first plate 11 and the second plate 12 can be formed into a main driver cabin front wall plate, and the right side area of the first plate 11 and the second plate 12 can be formed into a co-driver front wall plate. Since the left side area of the first plate 11 needs to be provided with a steering wheel and other operating parts, the right side area of the first plate 11 does not need to be provided with a steering wheel and other operating parts, thereby making the structures developed in the left side area of the first plate 11 and the right side area of the first plate 11 different, but the structures developed in the left side area of the second plate 12 and the right side area of the second plate 12 can be the same.
[0071] Therefore, by making the first plate 11 and the second plate 12 separate parts, the structures developed in the left side area of the second plate 12 and the right side area of the second plate 12 are the same, so that the structures developed in the left side area and the right side area of the front wall plate structure 10 can be shared, reducing the development cycle and reducing the cost.
[0072] The material strength of the second plate 12 can be higher than that of the first plate 11, and the thickness of the second plate 12 can be greater than that of the first plate 11, so that the structural strength at the second plate 12 is greater than that at the first plate 11. Since the second plate 12 is located at the lower side of the first plate 11, the lower side of the front part of the vehicle is usually the front area of the passenger compartment, which is the first barrier to transmit the collision energy when the vehicle suffers a front or side collision. Strengthening the crashworthiness of this area can effectively reduce the intrusion of the passenger compartment during a collision, thereby protecting the safety of the passengers.
[0073] In addition, since the first plate 11 and the second plate 12 are separate parts, the structural strength of the front wall plate structure 10 can be improved by improving and upgrading the material and thickness of the second plate 12, thereby improving the crashworthiness. At the same time, since only the material and thickness of the second plate 12 can be improved and upgraded, that is, the improvement and upgrading of part of the material of the front wall plate structure 10 is met, without the need to improve and upgrade all the materials of the front wall plate structure 10, thereby reducing the production cost.
