[0020] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following is for reference. Figures 1-6 The vehicle body structure 100 according to an embodiment of the present utility model.

[0022] like Figure 1 As shown, according to the first aspect embodiment of the present invention, the vehicle body structure 100 includes: a front bulkhead assembly 200, the front bulkhead assembly 200 including a front bulkhead front side panel 210, a front bulkhead rear side panel 220 and a front bulkhead bottom plate 230, the front bulkhead front side panel 210 and the front bulkhead rear side panel 220 being arranged spaced apart along the front-rear direction of the front bulkhead assembly 200, and the front bulkhead bottom plate 230 being connected between the front bulkhead front side panel 210 and the front bulkhead rear side panel 220; a structural reinforcement 300, a windshield lower crossbeam 400 and a tower structure 500, the windshield lower crossbeam 400 being located above the front bulkhead rear side panel 220, the tower structure 500 being located on the front side of the front bulkhead front side panel 210, the structural reinforcement 300 being installed on the front bulkhead front side panel 210, and the structural reinforcement 300 being fixedly connected to both the windshield lower crossbeam 400 and the tower structure 500.

[0023] Among them, such as Figure 1As shown, in this embodiment of the invention, the front bulkhead assembly 200 is aligned with the front-rear direction of the vehicle, and the length direction of the front bulkhead side panel 210 is defined as the left-right direction of the vehicle. The front bulkhead side panel 210, the rear bulkhead side panel 220, the front bulkhead bottom panel 230, and the vehicle's ventilation cover form a sealed space.

[0024] The front bulkhead assembly 200 can be made of materials such as steel or aluminum alloy. The front side panel 210, rear side panel 220, and bottom panel 230 can all be formed by stamping, high-pressure die casting, or other methods. As one embodiment, the bottom panel 230 can be integrally formed with the front side panel 210 and rear side panel 220. As another embodiment, the bottom panel 230 can be welded between the front side panel 210 and rear side panel 220. As yet another embodiment, the bottom panel 230 can be fixedly connected to the front side panel 210 and rear side panel 220 using fasteners such as bolts or clips.

[0025] The structural reinforcement 300, the lower crossbeam 400 of the windshield, and the tower structure 500 can all be made of materials such as steel and aluminum alloy. These components can be formed by stamping, mold casting, or other methods. In one embodiment, the front side panel 210 of the front bulkhead has an assembly opening 211 that extends through the front side panel 210 along its thickness direction, and the structural reinforcement 300 passes through this opening. In another embodiment, the structural reinforcement 300 can be installed on the front side panel 210 using bolts, clips, or other fasteners. In yet another embodiment, the structural reinforcement 300 can be welded to the front side panel 210. The structural reinforcement 300 can be arranged in a triangular or similar triangular pattern.

[0026] The structural reinforcement 300 and the lower windshield crossbeam 400 can be fastened together using bolts, clips, etc. The structural reinforcement 300 can also be welded to the lower windshield crossbeam 400. The structural reinforcement 300 can also be welded to the tower pack structure 500, and the structural reinforcement 300 and the tower pack structure 500 can be fastened together using bolts, clips, etc. The structural reinforcement 300 is installed on the front side panel 210 of the front bulkhead, and is fixedly connected to both the lower windshield crossbeam 400 and the tower pack structure 500. When a frontal collision occurs, the collision load can be transferred from the tower pack structure 500 to the structural reinforcement 300, and then from the structural reinforcement 300 to the lower windshield crossbeam 400. This helps to extend the energy transfer path, dispersing energy to multiple areas of the vehicle body structure 100 and reducing the risk of stress concentration in the vehicle body structure 100. Vibrations from the engine compartment can easily be transmitted to the passenger compartment through the front bulkhead assembly 200. The structural reinforcement 300 is installed on the front side panel 210 of the front bulkhead, and the structural reinforcement 300 is fixedly connected to the lower crossbeam 400 of the windshield and the tower structure 500. This helps to improve the structural stability of the body structure 100, improve the dynamic stiffness of the body structure 100, thereby improving the NVH performance of the vehicle, reducing the vibration transmission efficiency of the body structure 100, and reducing the vibration of the passenger compartment.

[0027] According to the vehicle body structure 100 of the first aspect embodiment of the present invention, by providing a structural reinforcement part 300, the present invention is beneficial to improving the structural stability of the vehicle body structure 100, improving the dynamic stiffness of the vehicle body structure 100, thereby improving the NVH performance of the vehicle, reducing the vibration transmission efficiency of the vehicle body structure 100, and reducing the vibration of the passenger compartment.

[0028] In some examples of embodiments of this utility model, such as Figure 1 , Figure 2 As shown, the structural reinforcement 300 includes a first reinforcement 310 and a second reinforcement 320. The first reinforcement 310 is installed on the front side panel 210 of the front bulkhead and is fixedly connected to the lower crossbeam 400 of the windshield. The second reinforcement 320 is located on the front side of the front side panel 210 of the front bulkhead and is fixed to the first reinforcement 310 and the corresponding tower structure 500.

[0029] In one embodiment, the front side panel 210 of the front bulkhead has a mounting opening 211 that extends through the front side panel 210 along its thickness direction, and the first reinforcing part 310 passes through the mounting opening 211. In another embodiment, the first reinforcing part 310 can be installed on the front side panel 210 using fasteners such as bolts or clips. The first reinforcing part 310 can be welded to the lower crossbeam 400 of the windshield, and can be fixedly connected using fasteners such as bolts or clips. The number of first reinforcing parts 310 can be one, two, or three, and the number of second reinforcing parts 320 can also be one, two, or three. This invention is illustrated using one first reinforcing part 310 and two second reinforcing parts 320 as an example.

[0030] The second reinforcing part 320 can be welded to the first reinforcing part 310, and the second reinforcing part 320 can be fixedly connected to the first reinforcing part 310 by fasteners such as bolts and clips. The second reinforcing part 320 can also be welded to the corresponding tower structure 500, and the second reinforcing part 320 can be fixedly connected to the corresponding tower structure 500 by fasteners such as bolts and clips. The collision, vibration, and other loads borne by the tower structure 500 can be first transferred to the second reinforcing part 320, then transferred to the first reinforcing part 310, and finally transferred to the lower crossbeam 400 of the windshield through the first reinforcing part 310, thus distributing the load to various parts of the vehicle. This helps to extend the energy transfer path, reduce energy transfer efficiency, and reduce the risk of stress concentration in the body structure 100.

[0031] In some examples of embodiments of this utility model, such as Figure 2 , Figure 3 As shown, the front side panel 210 of the front bulkhead has an assembly opening 211, which extends through the front side panel 210 along the thickness direction of the front bulkhead. The first reinforcing part 310 passes through the assembly opening 211.

[0032] In an exemplary embodiment, the dimensions of the mounting opening 211 are perfectly matched with the dimensions of the first reinforcing part 310. The mounting opening 211 penetrates the front side panel 210 of the front bulkhead, and the first reinforcing part 310 passes through the mounting opening 211. This helps to enhance the connection stability between the first reinforcing part 310 and the front side panel 210 of the front bulkhead, and helps to reduce the risk of the first reinforcing part 310 loosening. The collision, vibration, and other loads borne by the tower structure 500 can be first transferred to the second reinforcing part 320, then from the second reinforcing part 320 to the first reinforcing part 310, and finally through the first reinforcing part 310 to the lower crossbeam 400 of the windshield, thus distributing the load to various components of the vehicle. This transfer process bypasses the front side panel 210 of the front bulkhead, which helps to reduce the stress on the front side panel 210 of the front bulkhead, reduce the wear and tear on the front side panel 210, and extend the service life of the front side panel 210 of the front bulkhead.

[0033] When the first reinforcing part 310 passes through the assembly opening 211, the inner wall of the assembly opening 211 will limit the first reinforcing part 310, which can reduce the risk of the first reinforcing part 310 shifting and improve the structural stability of the vehicle body structure 100. Compared with the traditional vehicle body structure, the vehicle body structure 100 of this utility model, with the first reinforcing part 310 passing through the assembly opening 211, facilitates the assembly of the first reinforcing part 310 and the front side panel 210, which can shorten the assembly time of the vehicle body structure 100, improve the assembly efficiency of the vehicle body structure 100, and also improve the overall structural compactness of the first reinforcing part 310 and the front side panel 210.

[0034] In some examples of embodiments of this utility model, such as Figure 3 As shown, the front side panel 210 of the front bulkhead has a limiting edge 212 on the side facing the rear side panel 220 of the front bulkhead. The limiting edge 212 is arranged around the assembly opening 211 in the circumferential direction and fits against the first reinforcing part 310.

[0035] The limiting stop 212 is arranged circumferentially along the assembly opening 211 and fits against the first reinforcing part 310. This helps to limit the first reinforcing part 310, reducing the risk of swaying or displacement, enhancing its positional stability, and ensuring a more stable load transfer. It also reduces the risk of vibration or noise caused by loosening of the first reinforcing part 310, thus improving the vehicle's NVH performance. When the first reinforcing part 310 passes through the assembly opening 211, there is no need to repeatedly adjust its position to align with the center or edge of the opening; simply fitting the limiting stop 212 is sufficient to position the first reinforcing part 310 against the assembly opening 211. This further simplifies the assembly process of the vehicle body structure 100, shortens its assembly time, and improves its assembly efficiency.

[0036] The limiting stop 212 fits tightly with the first reinforcing part 310, which can reduce the gap between the assembly opening 211 and the first reinforcing part 310. This is beneficial to the sealing between the first reinforcing part 310 and the front side panel 210 of the front bulkhead, which helps to reduce the risk of engine compartment exhaust gas entering the sealed space through the gap. This further enhances the sealing performance of the sealed space and reduces the risk of engine compartment exhaust gas entering the sealed space through the gap. This also helps to reduce the risk of engine compartment exhaust gas invading the passenger compartment through the air conditioning vents and improves the air quality of the passenger compartment.

[0037] In some examples of embodiments of this utility model, such as Figure 4 , Figure 5 , Figure 6As shown, the first reinforcing part 310 includes: a first body 311, which passes through the assembly opening 211 and extends obliquely downward from the rear side panel 220 of the front bulkhead to the front side panel 210 of the front bulkhead; and a second reinforcing part 320 is fixed to the first body 311.

[0038] In an exemplary embodiment, the first body 311 is provided with a first structural reinforcing rib 313, which extends to the edge of the first body 311 in the front-rear and left-right directions, thereby improving the rigidity of the first body 311. The first structural reinforcing rib 313 extending in the front-rear direction can correspond with the second reinforcing part 320, further optimizing the load transfer path between them and improving the structural cooperative load-bearing capacity of the vehicle body structure 100. Vibrations of the tower pack structure 500 can be transmitted to the first body 311 through the second reinforcing part 320, and then buffered by the inclined path of the first body 311 before being transmitted to the lower windshield crossbeam 400. This helps reduce the risk of vibration concentrating locally in the vehicle body structure 100 and being converted into noise, thereby improving the NVH performance of the vehicle body structure 100 and optimizing the force transmission path. Furthermore, since the height of the lower windshield crossbeam 400 is higher than that of the tower pack structure 500, the first body 311 extends downwards at an angle, achieving a transition in height and facilitating the assembly of the first body 311 and the second reinforcing part 320.

[0039] In some examples of embodiments of this utility model, such as Figure 2 , Figure 6 As shown, the first reinforcing part 310 further includes: a second body 312 fixedly connected to the first body 311, the mounting opening 211 extending to the upper edge of the front side panel 210 of the front bulkhead, the second body 312 being located above the first body 311 and mounted on the mounting opening 211, the upper end of the second body 312 being flush with the upper end of the front side panel 210 of the front bulkhead, and the upper end of the second body 312 being fitted with a sealing structure.

[0040] The first body 311 and the second body 312 can be integrally formed. The second body 312 can be welded to the first body 311, and the second body 312 and the first body 311 can be fixedly connected by bolts, clips, or other fasteners. The sealing structure can be attached to the upper end of the second body 312 with high-strength double-sided adhesive, or it can be fastened to the upper end of the second body 312 with clips or other fasteners. The upper end of the second body 312 is flush with the upper end of the front side panel 210 of the front bulkhead. The sealing structure is located at the upper end of the second body 312 and contacts the ventilation cover to achieve a seal. This helps to reduce the risk of uneven local pressure and gaps in the sealing structure caused by the height difference between the upper end of the second body 312 and the upper end of the front side panel 210 of the front bulkhead. Meanwhile, the assembly port 211 extends to the upper edge of the front side panel 210 of the front bulkhead. The second body 312 is assembled in the assembly port 211, which can fill the gap at the upper edge of the front side panel 210 of the front bulkhead. This is beneficial to further enhance the sealing effect of the sealed space and further reduce the path of exhaust gas from the engine room into the crew compartment.

[0041] The upper end of the second body 312 is flush with the upper end of the front side panel 210 of the front bulkhead, and the second body 312 is assembled in the assembly port 211. This helps to prevent the second body 312 from protruding or sinking into the surface of the front side panel 210 of the front bulkhead. At the same time, the sealing structure is installed on the upper end of the flush second body 312 and the upper end of the front side panel 210 of the front bulkhead. This helps to prevent the sealing structure from having an uneven appearance due to the unevenness between the upper end of the second body 312 and the upper end of the front side panel 210 of the front bulkhead, thus meeting the aesthetic requirements of the vehicle body structure 100. The upper end of the second body 312 is flush with the upper end of the front side panel 210 of the front bulkhead. The sealing structure is assembled on the upper end of the second body 312. There is no need to adjust the installation height of the sealing structure. At the same time, the assembly port 211 extends to the upper edge of the front side panel 210 of the front bulkhead, which makes it easy for the second body 312 to be installed and positioned from above. This helps to reduce operational obstacles during the assembly of the second body 312, reduces the assembly difficulty of the sealing structure, and reduces the assembly time of the body structure 100, thereby improving the production and assembly efficiency of the body structure 100.

[0042] In some examples of embodiments of this utility model, such as Figure 1 As shown, there are two second reinforcing parts 320 and two tower structures 500. The two second reinforcing parts 320 are arranged along the length direction of the front side plate 210 of the front bulkhead, and the two tower structures 500 are arranged along the length direction of the front side plate 210 of the front bulkhead. The two second reinforcing parts 320 and the two tower structures 500 are assembled in a one-to-one correspondence.

[0043] Among them, the two tower-shaped structures 500 are arranged at intervals along the width direction of the vehicle, and the two second reinforcing parts 320 are arranged at intervals along the width direction of the vehicle. The interval between the upper ends of the two second reinforcing parts 320 along the width direction of the vehicle is smaller than the interval between the lower ends of the two second reinforcing parts 320 along the width direction of the vehicle. This is beneficial for adapting to the spatial layout of the body structure 100 and for optimizing the force transmission path.

[0044] The two second reinforcing sections 320 and the two tower pack structures 500 are assembled in a one-to-one correspondence, ensuring that the load of the left tower pack structure 500 is transferred by the left second reinforcing section 320, and the load of the right tower pack structure 500 is transferred by the right second reinforcing section 320. This helps to ensure the symmetry of the force on the body structure 100 and reduces the risk of twisting and deformation of the front side panel 210 due to uneven force on the left and right sides. Each second reinforcing section 320 corresponds to a tower pack structure 500, which allows the load of the tower pack structure 500 to be transferred to the corresponding second reinforcing section 320, and then from the corresponding second reinforcing section 320 to the first reinforcing section 310, and finally from the first reinforcing section 310 to the lower crossbeam 400 of the windshield. This helps to enhance the load-bearing and transfer capacity of the tower pack structure 500 against impact loads and reduces the risk of the tower pack structure 500 loosening or breaking during vehicle operation.

[0045] In some examples of embodiments of this utility model, such as Figure 1 As shown, the second reinforcing part 320 extends obliquely downward from the rear side panel 220 to the front side panel 210 of the front bulkhead.

[0046] The first body 311 and the second reinforcing part 320 are arranged in a downward direction to ensure that the structural reinforcing part 300 transitions along the vehicle height direction. This helps to avoid the risk of interference between the structural reinforcing part 300 and other components of the body structure 100, and also helps to optimize the spatial layout of the body structure 100. The first body 311 extends forward to the foremost part of the front side panel 210 and connects with the second reinforcing part 320, which ensures that the second reinforcing part 320 does not extend into the sealed space and affect the sealing effect of the sealed space.

[0047] When the vehicle is in motion, the tower pack structure 500 is prone to vertical or horizontal vibration. The second reinforcing part 320 extends downward at an angle, which can disperse and attenuate the vibration energy of the tower pack along the inclined path, reducing the intensity of vibration during transmission. At the same time, the second reinforcing part 320 extends downward at an angle, which can reduce the rigid collision between the second reinforcing part 320 and the front side panel 210 of the front bulkhead and the tower pack structure 500, and reduce the additional noise generated by the vibration friction between the second reinforcing part 320 and the front side panel 210 of the front bulkhead and the tower pack structure 500, which is beneficial to optimizing the NVH performance of the body structure 100.

[0048] In some examples of embodiments of this utility model, the vehicle body structure 100 further includes a sealing structure, which is disposed at the upper end of the front side panel 210 and extends along the length direction of the front side panel 210, and is used to contact the vehicle's ventilation cover.

[0049] The sealing structure can be made of elastic materials such as silicone rubber or nitrile rubber, and can be constructed as a solid sealing strip or a hollow sealing tube. The sealing structure can be attached to the upper end of the front panel 210 using high-strength double-sided adhesive, or it can be fastened to the upper end of the front panel 210 using fasteners such as snap-fit ​​devices. This invention will be illustrated by taking the example of the sealing structure being fastened to the upper end of the front panel 210.

[0050] After the front bulkhead assembly 200 and the ventilation cover are assembled, a sealed space is formed. The sealing structure is located at the upper end of the front side panel 210 of the front bulkhead and extends along the length of the front side panel 210. The sealing structure is used to contact the ventilation cover of the vehicle. This allows the sealing structure to fill the gap between the front side panel 210 of the front bulkhead and the ventilation cover through its own elastic deformation, which helps to improve the sealing performance of the sealed space and reduces the risk of exhaust gas in the engine compartment entering the sealed space through gaps. This helps to reduce the risk of exhaust gas in the engine compartment entering the passenger compartment through the air conditioning vents and improves the air quality of the passenger compartment.

[0051] The front bulkhead assembly 200 of this invention achieves good contact and sealing with the ventilation cover through a sealing structure, which reduces the risk of wind noise and vibration transmission caused by gaps between the front side panel 210 and the ventilation cover, thus improving the vehicle's NVH (noise, vibration, and harshness) performance. The body structure 100 of this invention has fewer parts, which simplifies the assembly process and reduces the number of special stamping dies required for its production, thereby lowering manufacturing and development costs. By placing the sealing structure at the upper end of the front side panel 210 and extending it along its length, this invention avoids the need for additional complex structures to achieve sealing, resulting in a more aesthetically pleasing overall structure of the body structure 100.

[0052] According to the first aspect of the present invention, the vehicle body structure 100 is beneficial to improving the sealing performance of the sealed space formed by the front bulkhead assembly 200 and the ventilation cover, which helps to reduce the entry of exhaust gas from the engine compartment into the sealed space through gaps, thereby reducing the risk of exhaust gas from the engine compartment entering the passenger compartment through the air conditioning vents, improving the air quality of the passenger compartment, improving the vehicle's NVH performance, reducing the manufacturing and development costs of the vehicle body structure 100, and making the overall structure of the vehicle body structure 100 more aesthetically pleasing.

[0053] The vehicle body structure 100 and other components and operations of the vehicle according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
