[0048] Combination Figure 1-6 As shown, the present invention provides a front bulkhead reinforcement structure for installation on a car, comprising: a lower front bulkhead baffle 1, a vacuum booster with brake pump reinforcement plate 3, an accelerator pedal connecting and fixing plate 4, and a front longitudinal beam 5. The lower front bulkhead baffle 1 is installed on the car; the vacuum booster with brake pump reinforcement plate 3 is connected to the lower front bulkhead baffle 1 and forms at least one first cavity 6 with the lower front bulkhead baffle 1, and the vacuum booster with brake pump reinforcement plate 3 is used to install the car's brake pedal; the accelerator pedal connecting and fixing plate 4 is connected to the vacuum booster with brake pump reinforcement plate 3 and forms a second cavity 7 with the vacuum booster with brake pump reinforcement plate 3, and the accelerator pedal connecting and fixing plate 4 is used to install the car's accelerator pedal; the front longitudinal beam 5 spans the lower front bulkhead baffle 1 and is connected to the lower front bulkhead baffle 1, and forms a third cavity 8 with the lower front bulkhead baffle 1.

[0049] In this embodiment of the invention, the lower front bulkhead 1 is the main component separating the car's driver's compartment and engine compartment. The steering column, brake pedal, and accelerator pedal are fixed together on the lower front bulkhead 1. The vacuum booster with brake pump reinforcement plate 3 includes a vacuum booster and a brake pump. The vacuum booster is a device that uses engine vacuum to enhance the force of the brake pedal, and the brake pump is a key component that converts the mechanical force of the brake pedal into fluid pressure. The vacuum booster and brake pump are combined and installed on the vacuum booster with brake pump reinforcement plate 3 for mounting the car's brake pedal, thus enhancing the structural strength of the brake pedal installation. The accelerator pedal connecting and fixing plate 4 is used to mount the car's accelerator pedal, thus enhancing the structural strength of the accelerator pedal installation. The front longitudinal beam 5 spans the lower front bulkhead 1, improving the overall strength of the front bulkhead reinforcement structure. The first cavity 6 formed by the vacuum booster with brake pump reinforcement plate 3 and the lower front bulkhead 1, the second cavity 7 formed by the accelerator pedal connecting and fixing plate 4 and the vacuum booster with brake pump reinforcement plate 3, and the third cavity 8 formed by the front longitudinal beam 5 and the lower front bulkhead 1 achieve the requirements for lightweighting and cost reduction of the car body front bulkhead structure.

[0050] Specifically, the vacuum booster with brake pump reinforcing plate 3 has multiple reinforcing ribs (not shown) on its surface. The reinforcing ribs and the front lower baffle 1 form at least one first cavity 6. The reinforcing ribs enhance the strength of the front body reinforcement structure.

[0051] Specifically, the front longitudinal beam 5 is located in the middle area of ​​the lower front baffle 1. Since the lower front baffle 1 has a large area, the middle area of ​​the lower front baffle 1 is not strong enough and is prone to deformation without support. The structure of the front longitudinal beam 5 makes up for the deficiencies of the structure of the lower front baffle 1.

[0052] More specifically, the accelerator pedal is located in the middle area of ​​the lower front baffle 1. After the front longitudinal beam 5 and the lower front baffle 1 form a longitudinal third cavity 8, the overall strength of the lower front baffle 1 is improved, which can effectively prevent the risk of accelerator pedal vibration.

[0053] In some embodiments, the front lower baffle 1 and the vacuum booster with brake pump reinforcing plate 3 at both ends of the first cavity 6 are connected by welding.

[0054] In this embodiment, the lower front bulkhead baffle 1 and the vacuum booster with brake pump reinforcing plate 3 are connected together by welding. This ensures the sealing of the first cavity 6 and enhances the connection strength between the lower front bulkhead baffle 1 and the vacuum booster with brake pump reinforcing plate 3. Moreover, welding is a low-cost method that enhances the strength of the front bulkhead of the vehicle body without increasing the thickness of the components or upgrading the material grade, thereby strengthening the installation structure of the brake pedal. Specifically, the lower front bulkhead baffle 1 and the vacuum booster with brake pump reinforcing plate 3 are welded together to form the first connecting part 13.

[0055] In some embodiments, the accelerator pedal connecting fixing plate 4 and the vacuum booster with brake pump reinforcing plate 3 at both ends of the second cavity 7 are connected by welding.

[0056] In this embodiment, the accelerator pedal connecting and fixing plate 4 and the vacuum booster with brake pump reinforcing plate 3 are connected together by welding. This ensures the sealing of the second cavity 7 and enhances the connection strength between the accelerator pedal connecting and fixing plate 4 and the vacuum booster with brake pump reinforcing plate 3. Moreover, welding is a low-cost method that enhances the strength of the front of the vehicle body without increasing the thickness of the components or upgrading the material grade, thereby strengthening the installation structure of the accelerator pedal. Specifically, the accelerator pedal connecting and fixing plate 4 and the vacuum booster with brake pump reinforcing plate 3 at both ends of the second cavity 7 are welded together to form the second connecting part 34.

[0057] In some embodiments, one end of the front longitudinal beam 5 is connected to the lower front baffle 1, and the other end is connected to the end of the vacuum booster with brake pump reinforcing plate 3 near the front longitudinal beam 5.

[0058] In this embodiment, the front longitudinal beam 5 is connected to the front lower baffle 1 and the vacuum booster with brake pump reinforcement plate 3 at both ends, which enhances the overall strength of the front body reinforcement structure.

[0059] In some embodiments, one end of the front longitudinal beam 5 at one end of the third cavity 8 and the lower front baffle 1 are connected by welding, and the lower front baffle 1, the vacuum booster with brake pump reinforcing plate 3, and the other end of the front longitudinal beam 5 at the other end of the third cavity 8 are connected by welding in sequence.

[0060] In this embodiment, one end of the front longitudinal beam 5 at one end of the third cavity 8 and the lower front baffle 1 are connected together by welding, which enhances the connection strength between the front longitudinal beam 5 and the lower front baffle 1. The lower front baffle 1, the vacuum booster with brake pump reinforcing plate 3, and the front longitudinal beam 5 at the other end of the third cavity 8 are also connected together by welding, further enhancing the connection strength between these components. Moreover, welding is a low-cost method that enhances the overall strength of the front body reinforcement structure without increasing the thickness of components or upgrading material grades. Specifically, one end of the front longitudinal beam 5 at one end of the third cavity 8 and the lower front baffle 1 are welded together to form a third connecting part 15, and the lower front baffle 1, the vacuum booster with brake pump reinforcing plate 3, and the front longitudinal beam 5 at the other end of the third cavity 8 are welded together to form a fourth connecting part 135.

[0061] In some embodiments, a clearance opening 9 is provided between the other end of the front longitudinal beam 5 and the accelerator pedal connecting fixing plate 4.

[0062] In this embodiment, the clearance 9 can prevent interference when the front longitudinal beam 5 or the accelerator pedal connecting and fixing plate 4 is welded to the front lower baffle 1 and the vacuum booster with brake pump reinforcing plate 3, and prevent the front longitudinal beam 5 and the accelerator pedal connecting and fixing plate 4 from being welded together.

[0063] In some embodiments, the front bulkhead reinforcement structure further includes a steering column hole cover 2, which is connected to the lower front bulkhead baffle 1 and is used to mount the vehicle's steering column.

[0064] In this embodiment, the steering column hole cover 2 can not only effectively prevent dust, dirt and moisture from entering the steering column of the car, protect the internal parts of the steering system and extend its service life, but also, the steering column hole cover 2 is connected to the lower baffle 1 of the front bulkhead, which can further enhance the overall strength of the front bulkhead reinforcement structure of the vehicle body.

[0065] In some embodiments, the front lower baffle 1, the steering column hole cover 2, and the vacuum booster with brake pump reinforcement plate 3 are connected sequentially by welding.

[0066] In this embodiment, the lower front bulkhead baffle 1, the steering column bore cover 2, and the vacuum booster with brake pump reinforcing plate 3 are connected together by welding. This enhances the connection strength between the lower front bulkhead baffle 1, the steering column bore cover 2, and the vacuum booster with brake pump reinforcing plate 3. Moreover, welding is a low-cost method that enhances the overall strength of the front bulkhead reinforcement structure without increasing the thickness of the components or upgrading the material grade. Specifically, the lower front bulkhead baffle 1, the steering column bore cover 2, and the vacuum booster with brake pump reinforcing plate 3 are welded together to form the fifth connection part 123.

[0067] Combination Figure 7As shown, the present invention also provides a method for installing a front bulkhead reinforcement structure of a vehicle body, including steps S10 to S50:

[0068] S10. Install the front lower baffle 1 onto the vehicle;

[0069] S20. Connect the steering column hole cover 2 to the lower front baffle 1.

[0072] S50. Connect the front longitudinal beam 5 of the front bulkhead to the lower baffle 1 of the front bulkhead, and form a third cavity 8 with the lower baffle 1 of the front bulkhead.

[0073] In this embodiment of the invention, the overall strength of the front structure of the vehicle body is enhanced by the vacuum booster with brake pump reinforcing plate 3, accelerator pedal connecting fixing plate 4 and front longitudinal beam 5, thereby increasing the strength of the pedal mounting structure. Moreover, the setting of the first cavity 6, the second cavity 7 and the third cavity 8 achieves the requirements of lightweighting and cost reduction of the front structure of the vehicle body.

[0074] Combination Figure 8 As shown, in some embodiments, the method for installing the front bulkhead reinforcement structure further includes steps S100 to S400:

[0075] S100. Weld the steering column hole cover 2 onto the lower front bulkhead 1.

[0076] S200, The front lower baffle 1 and the vacuum booster with brake pump reinforcing plate 3 at both ends of the first cavity 6 are connected by welding;

[0077] S300, the accelerator pedal connecting fixing plate 4 and the vacuum booster with brake pump reinforcing plate 3 at both ends of the second cavity 7 are connected by welding;

The lower baffle 1 of the front enclosure, the vacuum booster with brake pump reinforcing plate 3 and the other end of the front longitudinal beam 5 at the other end of the third cavity 8 are connected by welding in sequence.

[0079] In this embodiment, welding is a low-cost method that enhances the overall strength of the front bulkhead reinforcement structure without increasing the thickness of components or upgrading the material grade, thus further fulfilling the requirements for lightweighting and cost reduction of the automotive body front bulkhead structure.
