[0035] As shown in Figures 1-8 The present application provides a front frame mounting structure and a vehicle.

[0036] In an exemplary embodiment, the front frame mounting structure comprises:

[0037] The front wall beam assembly comprises the front wall lower reinforcing beam 1, the front longitudinal beam inner plate 3, the front wall cross beam assembly 2 and the front wall lower plate 4 connected with each other, and the front wall lower reinforcing beam 1, the front longitudinal beam inner plate 3, the front wall cross beam assembly 2 and the front wall lower plate 4 form the first closed space 9.

[0038] A reinforcing plate 5 is set on the lower reinforcing beam 1 of the front bulkhead. A second closed space 10 is formed between the reinforcing plate 5, the lower reinforcing beam 1 of the front bulkhead and the inner plate 3 of the front longitudinal beam. The second closed space 10 is located within the first closed space 9.

[0039] A connecting component, located within the second enclosed space 10, is used to connect the reinforcing plate 5 to the front lower reinforcing beam 1.

[0040] In this embodiment, the front bulkhead assembly is designed to include a front lower reinforcing beam 1, a front longitudinal beam inner plate 3, a front crossbeam assembly 2, and a front lower plate 4, all interconnected to form a first enclosed space 9. This effectively enhances the overall stability and rigidity of the front frame, improving the vehicle's responsiveness and safety during high-speed driving or aggressive handling. Simultaneously, a second enclosed space 10 is formed between the reinforcing plate 5 on the front lower reinforcing beam 1 and the front lower reinforcing beam 1 and the front longitudinal beam inner plate 3. The symmetrical arrangement of the two enclosed spaces and the second enclosed space 10 makes more efficient use of space and improves local strength without adding extra weight.

[0041] In this embodiment, the second enclosed space 10 is located within the first enclosed space 9. The double-layer sealing structure design helps improve the vehicle's sealing performance, reduces the intrusion of water, dust, and other impurities, and protects the internal structure of the frame from corrosion and damage. Simultaneously, the connecting assembly installed within the second enclosed space 10 connects the reinforcing plate 5 to the lower front bulkhead reinforcing beam 1. After the connecting assembly is installed as a whole onto the lower front bulkhead reinforcing beam 1, the reinforcing plate 5 is then installed onto the lower front bulkhead reinforcing beam 1, effectively securing the connecting assembly. This simplifies the connection method, reduces assembly complexity, and improves the strength and rigidity of the connecting assembly.

[0042] It is worth noting that in this embodiment, the front lower reinforcing beam 1, the front longitudinal beam inner plate 3, the front cross beam assembly 2, and the front lower plate 4 are welded together in pairs to improve the strength and rigidity of the front beam assembly.

[0043] It should also be noted that Figure 8 The diagram shows the first enclosed space 9 and the second enclosed space 10.

The mounting plate 7 is fixedly connected to the lower front bulkhead reinforcing beam 1, and the connectors 6 are fixedly connected to the mounting plate 7 and connected to the lower front bulkhead reinforcing beam 1.

[0045] In this embodiment, through the fixed connection of the mounting plate 7 and the lower front wall reinforcement beam 1, and the fixed connection of the connecting piece 6 and the mounting plate 7 and the lower front wall reinforcement beam 1, a firm connection system is formed, which significantly enhances the structural stability and load-bearing capacity of the entire front frame. At the same time, the design of at least two connecting pieces 6 can disperse the stress, reduce the load of a single connecting piece 6, and simplify the assembly process during installation, improve assembly efficiency and maintenance convenience.

[0046] For example, the mounting plate 7 is provided with mounting positions 701 corresponding in number to the connecting pieces 6, the connecting pieces 6 are arranged in the mounting positions 701 and fixedly connected with the mounting plate 7, and the mounting plate 7 further includes a plurality of fixed portions 702 capable of being fixedly connected with the lower front wall reinforcement beam 1. In this embodiment, the mounting plate 7 is in the shape of “Z” as a whole, and the plurality of fixed portions 702 at the lower edge thereof can be welded with the lower front wall reinforcement beam 1, so that the mounting plate 7 is firmly fixed on the lower front wall reinforcement beam 1.

[0047] It is worth noting that in this embodiment, the mounting plate 7 is provided with mounting positions 701 corresponding to the connecting pieces 6, ensuring that each connecting piece 6 can be precisely positioned at the predetermined position, and the connection with the lower front wall reinforcement beam 1 is more stable, enhancing the reliability and durability of the entire structure.

[0048] It is also worth noting that in this embodiment, the mounting plate 7 and the connecting piece 6 are fixed by welding, so that only the welding and fixation between the mounting plate 7 and the lower front wall reinforcement beam 1 need be performed during installation, the assembly process is further simplified, the assembly efficiency is improved, and the possibility of assembly errors is reduced.

[0049] It is also worth noting that in this embodiment, the connecting assembly can also be modularized, and different connecting assemblies can be designed for different vehicle models, so that the connecting assembly can be quickly adjusted and replaced according to different vehicle designs and requirements, improving the flexibility and adaptability of the design.

[0050] It is also worth noting that in this embodiment, the number of connecting assemblies is two, which are symmetrically arranged on the lower front wall reinforcement beam 1, so as to improve the connection effect when the front frame is connected subsequently.

[0053] Exemplarily, in this embodiment, the base 601 is welded with the lower front wall reinforcement beam 1 to provide stable support force.

[0054] Remarkably, in this embodiment, the support part 603 mainly supports the reinforcing plate 5, and through the cooperation of the two support parts 603 in supporting the same reinforcing plate 5, the support effect can be effectively improved.

[0055] It should also be noted that the base 601 adopts a countersunk design, which can provide good support force.

[0056] In an exemplary embodiment, the diameter of the support part 603 is smaller than the diameter of the main body 602, a support step 604 is formed between the main body 602 and the support part 603, the support part 603 penetrates out of the reinforcing plate 5, and the reinforcing plate 5 is overlapped with the support step 604.

[0057] In this embodiment, the design that the diameter of the support part 603 is smaller than the diameter of the main body 602 makes the stress distribution of the connecting piece 6 more reasonable when bearing load, enhancing the stability and strength of the connecting structure. At the same time, the support step 604 structure formed between the main body 602 and the support part 603 provides a precise mating surface for the reinforcing plate 5, which can position and preliminarily fix the reinforcing plate 5. The design that the support part 603 penetrates out of the reinforcing plate 5 and the reinforcing plate 5 is overlapped with the support step 604 realizes hidden connection, so that the connecting piece 6 is not conspicuous in appearance, improving the aesthetic appearance of the overall structure.

In this embodiment, the main body 602 is welded with the lower front wall reinforcement beam 1 to improve the connection effect, and the support step 604 surface formed by the support part 603 and the main body 602 is welded with the reinforcing plate 5, so as to improve the connection effect between the reinforcing plate 5 and the lower front wall reinforcement beam 1.

[0063] Exemplarily, the reinforcing rib 801 in the embodiment is a cylindrical sunken reinforcing rib formed by inwardly recessing the plane of the connecting plate 8, which can be fitted with the outer edge contour of the main body 602 of the connecting piece 6, so as to improve the supporting effect of the connecting piece 6 and enhance the strength of the connecting piece 6.
