Description

Technical Field

[0001] This specification relates to the field of automotive front bulkhead technology, and more particularly to a vehicle front bulkhead structure and vehicle. Background Technology

[0002] The front bulkhead of a car is a crucial component of the vehicle body structure, and its importance is reflected in multiple dimensions, directly affecting the vehicle's safety, comfort, and performance.

[0003] Traditional front bulkhead panels are typically made of 0.7–1.2 mm thick stamped steel sheets, which have relatively insufficient rigidity and require reinforcement to meet structural strength and installation rigidity requirements. However, the coverage area of ​​the brake pedal reinforcement plate is usually small, making it difficult to ensure installation rigidity in this area. During emergency braking, insufficient installation rigidity may cause significant deformation of the front bulkhead due to large pedal force, thus affecting braking safety. In addition, insufficient installation rigidity can also cause the driver to feel a softness when pressing the brake pedal, affecting the pedal feel.

[0004] Therefore, this specification provides a vehicle front bulkhead structure and a vehicle. Summary of the Invention

[0005] This specification provides a vehicle front bulkhead structure and a vehicle, which solves the problems existing in the prior art.

[0006] The following technical solution is adopted in this specification: This specification provides a vehicle front bulkhead structure, characterized in that it includes: a front bulkhead body, a brake pedal reinforcing plate, a brake pedal connecting plate, and an accelerator pedal mounting structure; The brake pedal reinforcing plate is attached to and fixedly connected to the front bulkhead body. The brake pedal reinforcing plate is used to enhance the installation strength and rigidity of the brake pedal. The accelerator pedal mounting structure is located on the side of the brake pedal reinforcing plate opposite to the front bulkhead body, and the accelerator pedal mounting structure is fixedly connected to the brake pedal reinforcing plate. A cavity structure is formed between the accelerator pedal mounting structure and the brake pedal reinforcing plate. The cavity structure is used to enhance the installation strength and rigidity of the brake pedal. The brake pedal connecting plate is attached to and fixedly connected to the front bulkhead body, and at least partially attached to the brake pedal reinforcing plate, so that it is configured together with the brake pedal reinforcing plate for mounting the brake pedal.

[0007] Based on the aforementioned technical means, this utility model can improve the installation strength and rigidity of the brake pedal. When faced with significant emergency braking force, it reduces deformation in the brake pedal mounting area, and the reduced deformation ensures stable braking force is applied to the brake pedal, thus improving braking safety. The accelerator pedal mounting structure is located on the outside of the brake pedal reinforcing plate and is fixedly connected to it, forming a cavity structure between the two. This effectively improves the overall structural rigidity of the area, not only facilitating the installation of the accelerator pedal but also indirectly strengthening the support capacity of the brake pedal area, achieving an integrated design of "one structure for multiple purposes."

[0008] Furthermore, the brake pedal reinforcing plate has a cylinder pressure rod circular hole and multiple brake pedal mounting points, with each brake pedal mounting point distributed around the cylinder pressure rod circular hole.

[0009] According to the aforementioned technical means, the circular hole of the brake master cylinder is used to install or pass through the push rod of the brake master cylinder (i.e., the brake master cylinder rod), and multiple brake pedal mounting points are arranged around this circular hole. The fixed position of the brake pedal is highly correlated with the axis of motion of the brake master cylinder rod. This layout ensures that after the brake pedal is installed, its rotation axis or force-bearing point is aligned with the brake master cylinder rod, guaranteeing a direct and efficient force transmission path, reducing off-center loads or stress concentration, and improving the linearity and reliability of the braking response.

[0010] Furthermore, a first reinforcing rib matching the front bulkhead body is formed on the brake pedal reinforcing plate; The first reinforcing rib is attached to the front bulkhead body to enhance the installation strength of the brake pedal.

[0011] Furthermore, a second reinforcing rib is formed on the front bulkhead body; a deformable portion is formed on the brake pedal connecting plate; The second reinforcing rib is attached to and fixedly connected to the brake pedal connecting plate; One end of the deformable part is formed with a first fixed connector, which is attached to and fixedly connected to the brake pedal reinforcing plate.

[0012] According to the above-mentioned technical means, the second reinforcing rib, combined with the deformable part, can improve the cooperative rigidity between the brake pedal connecting plate and the front bulkhead body. The cooperation between the two can prevent the brake pedal connecting plate from warping or slipping under stress. The first fixed connector connects to the brake pedal reinforcing plate, further enhancing the installation strength of the brake pedal.

[0013] Furthermore, a second fixing connector and a third fixing connector are respectively formed on opposite sides of the accelerator pedal mounting structure; The second fixing connector is fitted to the brake pedal reinforcing plate and fixedly connected to the brake pedal reinforcing plate; the third fixing connector is fitted to the brake pedal reinforcing plate and the front bulkhead body and fixedly connected to the brake pedal reinforcing plate and the front bulkhead body.

[0014] Based on the aforementioned technical means, the second and third fixed connectors together enhance the rigidity and durability of the accelerator pedal mounting structure.

[0015] Furthermore, a fourth fixing connector and a fifth fixing connector are respectively formed on the other two opposite sides of the accelerator pedal mounting structure; The fourth fixed connector and the fifth fixed connector are fixedly connected to the brake pedal reinforcement plate.

[0016] Furthermore, the cavity structure is located between the second fixed connector, the third fixed connector, the fourth fixed connector, and the fifth fixed connector.

[0017] Furthermore, the first fixed connector, the brake pedal reinforcing plate, and the front bulkhead body are sequentially bonded and welded together to form a three-layer welded structure.

[0018] Furthermore, the second, third, fourth, and fifth fixed connectors are respectively bonded and welded to the brake pedal reinforcing plate and the front bulkhead body in sequence to form a three-layer welded structure.

[0019] This specification provides a vehicle, including a vehicle body, characterized in that it further includes a vehicle front bulkhead structure as described above, the vehicle front bulkhead structure being mounted on the vehicle body.

[0020] The above-mentioned technical solutions adopted in this specification can achieve the following beneficial effects: This invention improves the installation strength and rigidity of the brake pedal, reducing deformation in the brake pedal mounting area when faced with large emergency braking forces. The reduced deformation ensures stable braking force is applied to the brake pedal, thus enhancing braking safety. The accelerator pedal mounting structure is located on the outside of the brake pedal reinforcing plate and is fixedly connected to it, forming a cavity structure between them. This effectively improves the overall structural rigidity of the area, not only facilitating accelerator pedal installation but also indirectly strengthening the support capacity of the brake pedal area, achieving an integrated design with "one structure for multiple purposes."

[0030] The technical solutions provided in the various embodiments of this specification are described in detail below with reference to the accompanying drawings.

[0031] A vehicle front bulkhead structure, such as Figure 1 and Figure 2As shown, the device includes a front bulkhead body 1, a brake pedal reinforcing plate 2, a brake pedal connecting plate 3, and an accelerator pedal mounting structure 4. The brake pedal reinforcing plate 2 is attached to and fixedly connected to the front bulkhead body 1, and serves to enhance the installation strength and rigidity of the brake pedal (not shown in the figure). The accelerator pedal mounting structure 4 is located on the side of the brake pedal reinforcing plate 2 opposite to the front bulkhead body 1, and is fixedly connected to the brake pedal reinforcing plate 2. A cavity structure 5 is formed between the accelerator pedal mounting structure 4 and the brake pedal reinforcing plate 2, which further enhances the installation strength and rigidity of both the brake pedal and the accelerator pedal (not shown in the figure). The brake pedal connecting plate 3 is attached to and fixedly connected to the front bulkhead body 1, and at least partially attached to the brake pedal reinforcing plate 2, so that it, together with the brake pedal reinforcing plate 2, is configured for mounting the brake pedal.

[0032] based on Figure 1 The vehicle front bulkhead structure shown enhances the installation strength and rigidity of the brake pedal, reducing deformation in the brake pedal mounting area under significant emergency braking force. This reduced deformation ensures stable braking force is applied to the brake pedal, improving braking safety. The accelerator pedal mounting structure 4 is located on the outside of the brake pedal reinforcing plate 2 and is fixedly connected to it, forming a cavity structure 5 between them. This effectively improves the overall structural rigidity of the area, facilitating accelerator pedal installation and indirectly strengthening the support capacity of the brake pedal area, achieving an integrated design with "one structure for multiple purposes."

[0033] In one or more embodiments of this specification, such as Figure 1 As shown, the brake pedal reinforcing plate 2 has a brake cylinder rod circular hole 21 and multiple brake pedal mounting points 22, which are distributed around the brake cylinder rod circular hole 21. The brake cylinder rod circular hole 21 is used to install or pass through the push rod of the brake master cylinder (i.e., the brake cylinder rod), while the multiple brake pedal mounting points 22 are arranged around the brake cylinder rod circular hole 21. The fixed position of the brake pedal is highly correlated with the movement axis of the brake cylinder rod. This ensures that after installation, the rotation axis or force point of the brake pedal is aligned with the brake cylinder rod, guaranteeing a direct and efficient force transmission path, reducing off-center load or stress concentration, and improving the linearity and reliability of the braking response.

[0034] In one or more embodiments of this specification, such as Figure 1 As shown, a first reinforcing rib 23 matching the front bulkhead body 1 is formed on the brake pedal reinforcing plate 2. The first reinforcing rib 23 is attached to the front bulkhead body 1 to improve the installation strength and rigidity of the brake pedal.

[0035] In one or more embodiments of this specification, such as Figure 1As shown, a second reinforcing rib 11 is formed on the front bulkhead body 1. A deformable part 31 is formed on the brake pedal connecting plate 3. One end of the brake pedal connecting plate 3 is attached to and fixedly connected to the second reinforcing rib 11, and a first fixed connector 32 is formed on one end of the deformable part 31 (i.e., the other end of the brake pedal connecting plate 3). The first fixed connector 32 is attached to and fixedly connected to the brake pedal reinforcing plate 2.

[0036] The second reinforcing rib, combined with the deformable part, enhances the overall rigidity between the brake pedal connecting plate and the front bulkhead body. This combination prevents the brake pedal connecting plate from warping or slipping under stress. The first fixed connector connects to the brake pedal reinforcing plate, further strengthening the installation of the brake pedal.

[0037] In one or more embodiments of this specification, such as Figure 1 , Figure 3 and Figure 4 As shown, a second fixing connector 41 and a third fixing connector 42 are formed on opposite sides of the accelerator pedal mounting structure 4. The second fixing connector 41 is fitted against and fixedly connected to the brake pedal reinforcing plate 2. The third fixing connector 42 is fitted against and fixedly connected to both the brake pedal reinforcing plate 2 and the front bulkhead body 1; that is, a portion of the third fixing connector 42 is fitted against and fixedly connected to the front bulkhead body 1, and the other portion is fitted against and fixedly connected to the brake pedal reinforcing plate 2.

[0038] Furthermore, a fourth fixing connector 43 and a fifth fixing connector 44 are respectively formed on the other two opposite sides of the accelerator pedal mounting structure 4. The fourth fixing connector 43 and the fifth fixing connector 44 are fixedly connected to the brake pedal reinforcing plate 2, further strengthening the installation strength of the accelerator pedal.

[0039] The second fixed connector 41, the third fixed connector 42, the fourth fixed connector 43, and the fifth fixed connector 44 together enhance the rigidity and durability of the accelerator pedal mounting structure 4.

[0040] In one or more embodiments of this specification, such as Figure 1 and Figure 2 As shown, the cavity structure 5 is located between the second fixed connector 41, the third fixed connector 42, the fourth fixed connector 43 and the fifth fixed connector 44.

[0041] In one or more embodiments of this specification, the first fixed connector 32, the brake pedal reinforcing plate 2, and the front bulkhead body 1 are sequentially bonded and welded together to form a three-layer welded structure.

[0042] In one or more embodiments of this specification, the second fixed connector 41, the third fixed connector 42, the fourth fixed connector 43, and the fifth fixed connector 44 are respectively bonded and welded to the brake pedal reinforcing plate 2 and the front bulkhead body 1 in sequence to form a three-layer welded structure.

[0043] The three-layer welded structure expands the welding contact area and enhances the overall load-bearing capacity of the connection, making it particularly suitable for complex stress environments such as shear force and bending moment. During long-term vehicle use, three-layer welding effectively prevents weld cracking and structural loosening. Multi-layer welding reduces gaps, preventing moisture and salt spray from penetrating the internal structure, thereby extending the service life of components.

[0044] This specification also provides a vehicle, including a vehicle body, and the aforementioned vehicle front bulkhead structure, which is mounted on the vehicle body. Installing this vehicle front bulkhead structure enhances the mounting strength of the brake pedal, reduces deformation in the brake pedal mounting area under significant emergency braking force, and ensures stable braking force is applied to the brake pedal, thus improving braking safety. The accelerator pedal mounting structure is located on the outside of the brake pedal reinforcing plate and is fixedly connected to it, forming a cavity structure between them. This effectively improves the overall structural rigidity of the area, not only facilitating the installation of the accelerator pedal but also indirectly strengthening the support capacity of the brake pedal area, achieving an integrated design of "one structure for multiple purposes."

[0045] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
