[0047] See Figures 1 to 21 As shown, this embodiment of the invention also provides a vehicle that includes the above-described front body compartment structure. The vehicle can also implement any embodiment of the front body compartment structure, which will not be described in detail here.

[0048] Specifically, Figure 1 This is a schematic diagram of the front compartment structure of the vehicle body. The differences between the technical solution proposed in this case and related technical solutions are reflected in areas A and B in the diagram. Area A mainly includes the upper longitudinal beam group 26, the A-pillar area 29, and the side longitudinal beam group 5, etc. Area B mainly includes the water channel 8, the upper front panel 16, the water channel reinforcement plate 23, and the wheel arch assembly 27, etc. The structure and layout of areas A and B differ from those of related technologies.

[0049] Figure 2 and Figure 3 This is a schematic diagram showing the structural and assembly relationship of sub-components in area A of the vehicle's front compartment. This proposal includes a first support plate 1, a second support plate 2, and a baffle 13 (see...). Figure 8 Components such as T-shaped reinforcing plate 4, the horizontal reinforcing plate 42O1O3 and the vertical reinforcing plate 41O2O4 of the T-shaped reinforcing plate 4 intersect at point O2. The related technology is generally an L-shaped reinforcing plate, namely O4O2O3.

[0050] Figure 5 , Figure 6 and Figure 8 This is a schematic diagram of a partial area of ​​the front compartment structure of the vehicle body. In this proposal, within area D1, there is a third support plate 6, a front bulkhead crossbeam 7, and a water channel 8. The third support plate 6 is used to connect and support the front bulkhead crossbeam 7 and the water channel 8, improving the rigidity and modal characteristics of the front compartment and optimizing the stress path of the front compartment. Within area D2, there are components such as a first reinforcing plate 10, a second reinforcing plate 11, a baffle 13, and a water channel 8, which connect the upper longitudinal beam group 26, the lower longitudinal beam group 28, the side longitudinal beam group 5, the wheel arch assembly 27, and the front bulkhead assembly 21, forming the stress-bearing section area D3. This improves the mechanical properties and collision safety performance of the front compartment area and optimizes the NVH performance of the vehicle body. Schematic diagram E of the partial area of ​​the front compartment structure shows the arrangement and assembly relationship between the above components from different angles.

[0051] Figures 9-11 This is a schematic diagram of the structure and assembly relationship of the front compartment components, showing the relative positions of components such as the connecting reinforcement area 9, the first reinforcement plate 10, and the second reinforcement plate 11. The connecting reinforcement area 9 includes the cover plate 12, the upper front bulkhead plate 16, the water channel 8 / water channel end plate 22, the corner plate 24, and the windshield support plate 25 (see...). Figure 13 and Figure 15 ) and other components.

[0052] See Figure 2 and Figure 11As shown, the design of components such as the side longitudinal beam assembly 5, the inner side longitudinal beam lower plate 14, and the inner side longitudinal beam upper plate 15 differs significantly from related technologies. In related technologies, the side longitudinal beam assembly 5 is located in the L2 region. In this proposal, the side longitudinal beam assembly 5 extends forward along the length of the vehicle body, setting a front L1 region, which is closely connected to the transverse reinforcing plate 42 of the T-shaped reinforcing plate 4 and the inner side longitudinal beam lower plate 14. The side longitudinal beam assembly 5 and the second reinforcing plate 11 are positioned opposite each other and are respectively located on both sides of the inner side longitudinal beam lower plate 14. The L3 front region of the inner side longitudinal beam lower plate 14 and the L4 front region of the inner side longitudinal beam upper plate 15 provide a connecting carrier for components such as the first support plate 1, the second support plate 2, the side longitudinal beam assembly 5, the first reinforcing plate 10, and the second reinforcing plate 11, providing an expanded basis for optimizing the structural layout of the front compartment A region of the vehicle body. The above structural settings change the layout structure and assembly relationship of the front compartment A region of the vehicle body, optimize the force path of the front compartment region of the vehicle body, and improve the mechanical performance and collision safety performance of the front compartment region of the vehicle body.

[0053] Figure 12 This is a schematic diagram of the force path in the front compartment area of ​​the vehicle body. With the matching of structures such as the first support plate 1, the second support plate 2, the side outer panel 3, the T-shaped reinforcing plate 4, the connecting reinforcing area 9, the first reinforcing plate 10, the second reinforcing plate 11, the baffle 13, the upper longitudinal beam group 26, the lower longitudinal beam group 28, the side longitudinal beam group 5, and the front bulkhead assembly 21, force nodes C1 to C12 are formed, optimizing the force path in the front compartment area and improving the mechanical properties and collision safety performance of the front compartment area.

Figure 13 Includes windshield support plate 25, to clearly demonstrate the internal sub-component structure and assembly relationship of area B. Figure 14 A partial schematic diagram of the windless support plate 25; Figures 15-17 This is a partial schematic diagram of the structure and assembly relationship of sub-components in area B of the front compartment of the vehicle body. It shows the arrangement and assembly relationship of components such as water channel 8, cover plate 12, front bulkhead upper plate 16, third connecting plate 19, support tube beam assembly 20, water channel reinforcing plate 23, and corner plate 24 in area B of the front compartment of the vehicle body, as well as the structural features of the sub-components.

[0055] Figures 18-21This is a schematic diagram of the sub-component layout scheme for area B of the vehicle's front compartment. By optimizing the layout and assembly relationships of the various sub-components in area B, different combination methods are formed, increasing the compatibility and expandability of area B. This proposal presents the following four combination schemes, but is not limited to them. Specifically, combination scheme one includes three parts: a water channel 8, a water channel reinforcing plate 23, and a front bulkhead upper plate 16, illustrated by H1-H2 and J1-J2. The water channel reinforcing plate 23 is tightly connected to the water channel 8 to enhance the structural stability of the water channel 8 and improve the lateral stiffness of the front compartment. The water channel reinforcing plate 23 can be configured according to performance requirements. Combination scheme two includes two parts: a front bulkhead upper plate 16 and a supporting tube beam assembly 20, illustrated by H1-H2 and K1-G3-K4. Combination scheme three includes the front bulkhead upper plate 16, the supporting tube beam assembly 20, the first connecting plate 17, the third connecting plate 19, and the water channel end plate 22, illustrated by H1-H2, K1-G1-G3, K1-G3-K4, and G3-G5-K4, forming a stress-bearing area.

With the cooperation of nodes such as G1-G5, H1-H2, J1-J2, K1-K4, etc., there are multiple arrangement schemes between the various parts, not limited to the above illustrated schemes. Under the comprehensive effect of stress nodes, stress areas and frame structures, the bending stiffness and torsional stiffness of the front compartment of the vehicle body are improved, the dynamic stiffness of the front shock absorber mounting point is improved, the mechanical performance and NVH performance of the front compartment of the vehicle body are improved, and the comfort of the occupants inside the vehicle is improved.
