[0001] This utility model relates to a segmented front bulkhead assembly, belonging to the field of automotive parts technology. Background Technology

[0002] The front bulkhead is a key component of the car body structure, located between the engine compartment and the passenger compartment. Its main function is to isolate the noise and heat from the engine compartment, and at the same time prevent parts from the engine compartment from entering the passenger compartment in the event of a collision, thereby protecting the safety of the occupants.

[0003] The placement of the brake pedal is a crucial consideration in vehicle design. However, due to limitations in existing front bulkhead structures, the space available for the brake pedal is often cramped, making it difficult to meet regulatory requirements. Furthermore, both designing a new front bulkhead to meet specifications and developing a new brake pedal that complies with placement regulations require mold-making costs. Utility Model Content

[0005] This utility model provides a segmented front bulkhead assembly, which includes an upper front bulkhead, a lower front bulkhead, a left connecting plate, and a right connecting plate. The left and right connecting plates are symmetrically arranged on both sides of the lower front bulkhead. The upper, left, and right connecting plates have a trough structure. The lower front bulkhead has a notch corresponding to a brake pedal mounting bracket. The brake pedal mounting bracket has a through hole.

[0006] Preferably, the lower front panel is located below the upper front panel, and the upper front panel, lower front panel, left connecting plate, and right connecting plate are integrally formed.

[0013] Preferably, the second sound insulation cotton is provided with an airbag on the outside, and the airbag covers the second sound insulation cotton.

[0014] Preferably, there are multiple airbags, and the multiple airbags are evenly distributed between the first sound insulation cotton and the third sound insulation cotton.

[0015] The beneficial effects of this utility model are:

[0016] This utility model provides a segmented front bulkhead assembly, which integrates the upper front bulkhead, lower front bulkhead, left connecting plate, and right connecting plate into a single piece, greatly enhancing the structural rigidity and stability of the entire front bulkhead assembly, reducing seams between components, improving overall sealing and durability, and contributing to improved overall vehicle safety performance. The trough structure set in the upper front bulkhead, left connecting plate, and right connecting plate not only increases the space inside the engine compartment, but also improves the structural strength of the front bulkhead through the geometry of the troughs.

[0025] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] Example 1: This utility model provides a segmented front bulkhead assembly, which includes an upper front bulkhead 1, a lower front bulkhead 2, a left connecting plate 3, and a right connecting plate 4. The lower front bulkhead 2 is located below the upper front bulkhead 1, and the left connecting plate 3 and the right connecting plate 4 are symmetrically arranged on both sides of the lower front bulkhead 2. The upper front bulkhead 1, the lower front bulkhead 2, the left connecting plate 3, and the right connecting plate 4 are integrally formed. The upper front bulkhead 1, the left connecting plate 3, and the right connecting plate 4 are provided with a trough structure. The top of the upper front bulkhead 1 is concave towards the rear of the vehicle to form a first trough 11, and the middle of the left connecting plate 3 and the right connecting plate 4 is concave towards the rear of the vehicle to form a second trough 31. This increases the space in the engine compartment and can improve the structural strength of the upper front bulkhead 1, the left connecting plate 3, and the right connecting plate 4 by utilizing the trough structure. The outer sides of the upper front bulkhead 1, the lower front bulkhead 2, the left connecting plate 3, and the right connecting plate 4 are all provided with flanges, which facilitates the connection and assembly of the front bulkhead assembly with other vehicle components.

[0027] The lower front panel 2 is provided with a fixedly connected brake pedal mounting bracket 5. The lower front panel 2 has a notch corresponding to the brake pedal mounting bracket 5. The brake pedal mounting bracket 5 is located on the side of the lower front panel 2 near the engine compartment. The brake pedal mounting bracket 5 has a through hole 51. The brake pedal is mounted on the brake pedal mounting bracket 5 through the through hole 51 and extends into the cockpit.

[0028] In use, the front bulkhead upper panel 1, front bulkhead lower panel 2, left connecting panel 3, and right connecting panel 4 are integrally formed. The flanges on the outer side facilitate the connection of the front bulkhead assembly with other components. The trough structure on the front bulkhead upper panel 1, left connecting panel 3, and right connecting panel 4 can improve the structural strength of the front bulkhead assembly. The troughs absorb impact energy and transfer the impact energy to both sides of the troughs, preventing the impact force on the front bulkhead from being dispersed into the cockpit and causing injury to passengers. It can also increase the area inside the engine compartment. The brake pedal mounting bracket 5 is located on the front bulkhead lower panel 2 on the side close to the engine compartment. The front bulkhead lower panel 2 has a notch corresponding to the brake pedal mounting bracket 5. The notch is a clearance opening, thereby increasing the space for brake pedal arrangement and movement.

[0029] Compared with existing technologies, by designing the upper front bulkhead 1, lower front bulkhead 2, left connecting plate 3, and right connecting plate 4 as a single piece, the structural rigidity and stability of the entire front bulkhead assembly are enhanced, the seams between components are reduced, and the overall sealing and durability are improved. The first trough 11 at the top of the upper front bulkhead 1 and the second trough 31 in the middle of the left and right connecting plates 3 and 4 not only increase the space inside the engine compartment but also improve the structural strength of the front bulkhead through the geometry of the troughs. The trough structure can effectively absorb and disperse impact energy, reducing the potential injury to passengers in the cockpit. The outer sides of the upper front bulkhead 1, lower front bulkhead 2, left connecting plate 3, and right connecting plate 4 are all provided with flanges, simplifying the connection and assembly process between the front bulkhead assembly and other vehicle components. The flange provides additional connection area, enhancing the strength and stability of the connection. The brake pedal mounting bracket 5 is fixedly connected to the lower front panel 2, and the lower front panel 2 has a notch corresponding to the brake pedal mounting bracket 5, making the installation of the brake pedal easier. At the same time, the notch provides the necessary arrangement and movement space for the brake pedal, optimizing the use of space inside the vehicle.

[0030] Example 2: No sound insulation material was used in the above examples, resulting in poor sound insulation effect. Furthermore, the existing sound insulation materials are limited and cannot effectively isolate noise of different frequencies. Therefore, this application example is an optimization based on the above examples.

[0031] This embodiment also includes a sound insulation section 6, which is located on the side of the front upper panel 1, front lower panel 2, left connecting plate 3, and right connecting plate 4 near the engine compartment. The sound insulation section 6 includes a first sound insulation cotton 61, a second sound insulation cotton 62, and a third sound insulation cotton 63. The first sound insulation cotton 61, the second sound insulation cotton 62, and the third sound insulation cotton 63 are arranged sequentially from the outside to the inside and are connected sequentially by a buckle assembly. The third sound insulation cotton 63 is fixed to the front upper panel 1, the front lower panel 2, the left connecting plate 3, and the right connecting plate 4 by bolts 64. The bottom of the third sound insulation cotton 63 is provided with a magnetic suction plate 01, and the third sound insulation cotton 63 is attracted to the front panel assembly by the magnetic suction plate 01. The first sound insulation cotton 61 and the third sound insulation cotton 63 are both honeycomb designs. The first sound insulation cotton 61 and the second sound insulation cotton 62 are made of high-density high-frequency sound insulation material, while the third sound insulation cotton 63 is made of low-density sound insulation material.

[0032] During use, the sound insulation section 6 is attached to the front bulkhead assembly 02 by the magnetic plate 01 on the third sound insulation cotton 63 and fixed to the front bulkhead assembly 02 by bolts 64. The second sound insulation cotton 62, the third sound insulation cotton 63 and the first sound insulation cotton 61 are fixedly connected to each other by a snap-fit ​​assembly. The first sound insulation cotton 61 and the third sound insulation cotton 63 have a honeycomb design to improve the sound absorption and sound insulation performance of the sound insulation cotton. The first sound insulation cotton 61 and the second sound insulation cotton 62 are made of high-density high-frequency sound insulation material, which can better isolate high-frequency noise at the front end. The third sound insulation cotton 63 is made of low-density sound insulation material to absorb low-frequency noise, further improving the sound insulation effect of the front bulkhead and reducing the impact of engine compartment noise on the passenger compartment.

[0033] Compared with existing technologies, the design of three layers of sound insulation cotton, connected by snap-fit ​​components, forms a multi-layer sound insulation structure that significantly improves sound insulation performance and effectively blocks engine compartment noise from affecting the passenger compartment. The first and second sound insulation cotton 61 and 62 use high-density, high-frequency sound insulation materials to better isolate high-frequency noise at the front end; while the third sound insulation cotton 63 uses low-density sound insulation materials to absorb low-frequency noise. The honeycomb design of the first and third sound insulation cotton 61 and 63 increases the surface area of ​​the sound insulation cotton, improving sound absorption and sound insulation performance. At the same time, the honeycomb structure also has a certain degree of elasticity, which can buffer and absorb noise energy, further enhancing the sound insulation effect. This material combination allows the sound insulation section 6 to effectively deal with both high-frequency and low-frequency noise, improving the overall sound insulation effect. By setting a magnetic suction plate 01 at the bottom of the third sound insulation cotton 63, the sound insulation section 6 can be easily attached to the front bulkhead assembly. At the same time, the third sound insulation cotton 63 is fixed to the front bulkhead assembly by bolts 64, ensuring the stability of the sound insulation section 6 during vehicle operation.

[0034] Example 3: In the above examples, the sound insulation material is a static structure, mainly reducing noise transmission through the material's sound absorption and sound insulation properties, but it cannot effectively reduce the resonance effect during noise transmission. The resonance effect causes noise to be amplified at specific frequencies, thereby increasing the impact of noise on the passenger compartment. Therefore, this application embodiment optimizes the second sound insulation cotton 62 based on the above embodiments.

[0035] In this embodiment, an airbag 65 is provided on the outside of the second sound insulation cotton 62. The airbag 65 wraps the second sound insulation cotton 62. The outside of the airbag 65 contacts the bottom of the first sound insulation cotton 61 and the top of the third sound insulation cotton 63. The airbag 65 consists of multiple airbags that are evenly spread between the first sound insulation cotton 61 and the third sound insulation cotton 63.

[0036] When in use, the airbag 65 acts as a dynamic sound insulation structure. When noise is generated in the engine compartment, the airbag 65 can absorb some of the noise energy through micro-vibration, effectively absorbing and dissipating the noise energy. In addition, the airbag 65 can also reduce the resonance effect during the noise transmission process, which can further reduce the impact of engine compartment noise on the passenger compartment and improve the overall sound insulation performance of the front bulkhead.

[0037] Compared with existing technologies, when noise is generated in the engine compartment, the airbag 65 can absorb some of the noise energy through micro-vibration, making the airbag 65 more effective in absorbing and dissipating noise energy. Compared with static sound insulation materials, its sound insulation effect is more significant. Its micro-vibration can disperse and dissipate noise energy, effectively reduce the resonance effect in the noise transmission process, further reduce the impact of engine compartment noise on the passenger compartment, and improve the overall sound insulation performance of the front bulkhead.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
