Description

Technical Field

[0001] This application relates to the field of vehicle component technology, and in particular to a front windshield reinforcement assembly and a vehicle. Background Technology

[0002] With the development of automotive technology, car design has begun to shift from structural design to performance design. Issues such as corrosion, water leakage, and noise have become urgent problems for OEMs to solve. The windshield reinforcement assembly, located at the bottom of the windshield, is a crucial component supporting the glass and connecting the left and right side panels, front bulkhead, and heater core. It significantly impacts the vehicle's torsional stiffness and modal characteristics. The heater core, connected to it, is a major drainage structure in the front of the vehicle, operating in a relatively harsh environment. Furthermore, the windshield reinforcement assembly provides the mounting structure for the engine compartment sound insulation pad. An inadequate structure can easily lead to corrosion, water leakage, and noise, affecting vehicle quality and passenger comfort.

[0003] Related technologies include improving the drainage structure on the pressure chamber plate of the heater core. For example, a water-blocking part can be installed at the front of the windshield reinforcement, directly above the air conditioning inlet, to solve the leakage problem; or sealant can be applied between the windshield and the lower crossbeam to improve the sealing at the joint. However, all of these methods suffer from poor sealing performance and complex structures. Summary of the Invention

[0004] Therefore, this application provides a front windshield reinforcement assembly and vehicle, which has the advantages of good sealing effect and simple structure.

[0005] In a first aspect, embodiments of this application provide a front windshield reinforcement assembly disposed between the air chamber panel and the front wall panel. The front windshield reinforcement assembly includes a windshield reinforcement member, an upper front windshield crossbeam, and a lower front windshield crossbeam. The upper front windshield crossbeam is located below the windshield reinforcement member; both the front windshield reinforcement member and the lower front windshield crossbeam are located above the front wall panel, and the three are sequentially overlapped along the side edges in the vehicle width direction to form a cavity structure. The upper front windshield crossbeam has a first mounting surface and a second mounting surface with a stepped transition. The first mounting surface has a connecting structure for connection with the air chamber panel; a first sealing element is pressed tightly against the first mounting surface and the air chamber panel; a second sealing element is pressed tightly against the second mounting surface and the windshield.

[0006] Specifically, the windshield reinforcement is located between the upper and lower crossbeams of the windshield. The end of the upper crossbeam of the windshield, near the air chamber panel along the length of the vehicle body, is connected to the air chamber panel, and the connection method is not limited, such as screwing or welding. The end of the upper crossbeam of the windshield away from the air chamber panel is a free end. The free end of the air chamber panel has a certain gap with the instrument panel assembly and the front wall panel assembly along the length of the vehicle body to reduce the stiffness of the upper crossbeam area of ​​the windshield, so that a certain crumple space is formed when the vehicle collides with a pedestrian, thereby reducing the injury to the pedestrian. Furthermore, the design of the front windshield reinforcement, the lower front windshield crossbeam, and the front panel being sequentially overlapped along the side of the vehicle body to form a cavity structure can significantly improve the strength of the front of the vehicle, enhance the force transmission effect in frontal and side collisions, thereby improving the overall modal and torsional stiffness of the front of the vehicle and reducing the injury to pedestrians in the event of a collision. Moreover, compared to the cavity structure composed of the upper front windshield crossbeam, the lower front windshield crossbeam, and the front windshield reinforcement, the location and structure of the front panel are not easily altered. Therefore, only the structural design and layout of the front windshield reinforcement and the lower front windshield crossbeam need to be adjusted to easily form a cavity structure between the front windshield reinforcement, the lower front windshield crossbeam, and the front panel, making the structure of the front windshield reinforcement assembly simpler and easier to implement.

[0007] Since the windshield reinforcement assembly is located at the bottom of the windshield, it is a crucial component supporting the glass and connecting the left and right side panels, front bulkhead, and heater pressure chamber plate. The heater pressure chamber plate, which it connects to, is a major drainage structure at the front of the vehicle, operating in a relatively harsh environment. If the structure is flawed and the sealing is poor, water can easily enter the engine compartment, dashboard assembly, and other components, leading to corrosion, leaks, and affecting vehicle quality and ride comfort. Therefore, to address the poor sealing issue, this application incorporates a first sealing element and a second sealing element, respectively, pressed and adhered between the first mounting surface and the air chamber plate, and between the second mounting surface and the windshield. This means two sealing structures are directly installed on the upper crossbeam of the windshield, reducing water leakage from the air chamber and engine compartment. Furthermore, the placement of both sealing structures on the upper crossbeam of the windshield results in a simple and rational structural layout for the windshield reinforcement assembly.

[0008] It should be noted that the positions of the first and second mounting surfaces on the upper crossbeam of the windshield are not limited, nor are their specific structures. For example, the first and second mounting surfaces can be mounting bosses spaced apart on the outer wall of the upper crossbeam of the windshield, or they can be integrally formed on the outer wall of the upper crossbeam of the windshield. Preferably, the first and second mounting surfaces are two stepped mounting bosses on the same side of the outer wall of the upper crossbeam of the windshield. Here, a stepped transition means that the two mounting bosses have different heights along their extension direction. This facilitates the separate installation of the first and second seals on the first and second mounting surfaces, thus avoiding interference between the first and second seals when their end faces are on the same plane.

[0009] Additionally, it should be noted that the air chamber panel in this application is the same as the commonly referred to heater pressure chamber panel assembly. Located above the front bulkhead and below the windshield, the heater pressure chamber panel assembly primarily functions to drain water from the vehicle and provide air conditioning intake. Structurally, it improves the vehicle's torsional rigidity. This structure also plays a crucial role in pedestrian protection during collisions, body modal analysis, and corrosion resistance. By placing the heater pressure chamber panel structure between the windshield and the front bulkhead, a larger transition area is created, allowing liquid flowing from the windshield to collect on the heater pressure chamber panel structure instead of flowing directly into the front compartment. This improves the vehicle body's ability to guide liquids and reduces the possibility of liquid entering the front compartment.

[0010] The connection structure for connecting the air chamber plate on the first mounting surface is not limited. For example, the connection structure may be threaded holes provided on one end of the air chamber plate near the first mounting surface and on the first mounting surface, and the two can be detachably connected by bolts passing through the threaded holes on the air chamber plate and the second mounting surface in sequence; or a welding part is provided on the first mounting surface, and the two are welded together by welding. This application embodiment does not limit this.

[0011] In one possible implementation of this application, a first flange is formed at the end of the upper crossbeam of the windshield near the air chamber panel, and a second flange is formed at the opposite end. A first mounting surface is disposed on the first flange, and a sound-insulating component is pressed and fitted between the second flange and the front wall panel. Preferably, the first flange is formed at the end of the upper crossbeam of the windshield near the air chamber panel, and the second flange is formed at the opposite end. Here, the first flange is directly formed on the upper crossbeam of the windshield, increasing the mounting space on the upper crossbeam. Furthermore, placing the first mounting surface on the first flange facilitates the spacing between the first and second mounting surfaces, thereby facilitating the placement of a first sealing component on the first mounting surface. Additionally, the design of pressing and fitting a sound-insulating component between the second flange and the front wall panel improves the overall vehicle's leak-proof, vibration-damping, and noise-reducing performance.

[0012] It should be noted that the sound insulation component here has a sheet-like structure, which facilitates better adhesion between the front bulkhead and the upper crossbeam of the windshield. The first and second flanges at opposite ends of the upper crossbeam of the windshield create a Z-shaped cross-section of the entire upper crossbeam perpendicular to the vehicle's width. This effectively increases the coverage area of ​​the engine compartment sound insulation component, which adheres to the flanged structure of the engine compartment front bulkhead and the upper crossbeam of the windshield, compared to the coverage area of ​​the upper crossbeam of the windshield without the flanged structure. This results in better overall vehicle performance in terms of leak prevention, vibration isolation, and noise reduction. Specifically, the Z-shaped cross-section of the upper crossbeam of the windshield allows for additional flanges in the engine compartment sound insulation component and enables the installation points of the sound insulation component to be located on the upper crossbeam of the windshield and extend to the windshield. This results in a larger coverage area of ​​the sound insulation component in the front bulkhead area, leading to better sealing, sound insulation, and noise reduction.

[0013] In one possible implementation of this application, a plurality of first mounting bosses are further provided on the first mounting surface, each mounting boss having a mounting hole. The connection structure is a mounting hole, which is used to screw or snap onto the upper crossbeam of the windshield and the air chamber plate using fasteners. The reason for providing multiple first mounting bosses on the first mounting surface and screwing or snapping onto the upper crossbeam of the windshield via mounting holes on the first mounting bosses, rather than directly creating mounting holes on the first mounting surface, is to facilitate the installation of the first seal on the first mounting surface. Specifically, the presence of the first mounting bosses serves two purposes: firstly, it avoids obstructing the installation of the first seal; secondly, because there is a certain distance difference between the end face of the first mounting boss away from the first mounting surface and the first mounting surface, a space is formed between the end face of the first mounting boss away from the first mounting surface and the first mounting surface for accommodating the first seal. This facilitates the fit of the first seal between the first mounting surface and the air chamber plate.

[0014] In one possible implementation of this application, a plurality of second mounting protrusions are provided on the second mounting surface facing the windshield, and a second seal is disposed on the second mounting protrusions. Thus, based on the first seal formed between the upper crossbeam of the windshield and the air chamber panel, the second seals disposed on the second mounting protrusions create a sealed structure between the windshield and the windshield reinforcement assembly, preventing liquid flowing down from the windshield from entering the vehicle's engine compartment via the upper crossbeam of the windshield.

[0015] In one possible implementation of this application, the second flange has a sound insulation mounting surface and a sound insulation mounting recess; wherein there are multiple sound insulation components, and at least two sound insulation mounting surfaces are respectively disposed at both ends of the upper crossbeam of the front windshield along its length; there are multiple sound insulation mounting recesses, which are spaced apart along the extension direction of the upper crossbeam of the front windshield, for installing sound insulation components between the second flange and the front wall panel. The placement of the sound insulation mounting recesses can facilitate the installation of the sound insulation components. Furthermore, because there is a certain distance difference between the end face of the sound insulation mounting recess away from the sound insulation mounting surface and the sound insulation mounting surface, a space for arranging the sound insulation components is formed between the end face of the sound insulation mounting recess away from the sound insulation mounting surface and the sound insulation mounting surface, thus facilitating the close-fitting installation of the sound insulation components between the sound insulation mounting surface and the front wall panel.

[0016] In one possible implementation of this application, both the mounting surface and the mounting recess of the sound insulation component are provided with sound insulation component snap-fit ​​holes, and the opening direction of the sound insulation component snap-fit ​​holes faces the height direction of the vehicle body. The sound insulation component snap-fit ​​holes are used to snap the snap-fit ​​portion on the sound insulation component into the sound insulation component snap-fit ​​holes, and the sound insulation component can be pressed and fitted against the front wall panel along the extension direction of the front wall panel through multiple sound insulation component mounting recesses. Here, the design of the sound insulation component snapping into the sound insulation component snap-fit ​​holes, compared with the design of installing the sound insulation component on the front wall panel along the length direction of the vehicle body by mounting studs, can greatly increase the coverage area of ​​the sound insulation component on the front wall panel, thereby improving the overall sealing, sound insulation and noise reduction effect of the vehicle.

[0017] In one possible implementation of this application, a third mounting surface is provided on the upper crossbeam of the windshield. This third mounting surface is positioned between the first and second flanges, and it includes multiple instrument panel mounting surfaces and multiple instrument panel mounting bosses for mounting instrument components. This improves the integration of the upper crossbeam of the windshield, allowing multiple functional components to be integrated onto it. The instrument panel mounting surfaces and bosses are positioned on the upper crossbeam of the windshield because it has at least three sealing structures: at least three sealing structures between the upper crossbeam and the air chamber panel, the windshield, and the front bulkhead. These seals provide rust and leakage protection for the instrument components in the passenger compartment. Furthermore, since the upper crossbeam of the windshield and the instrument panel assembly are approximately at the same height along the vehicle body, the instrument panel mounting surfaces and bosses facilitate alignment and installation with the instrument components.

[0018] In one possible implementation of this application, the third mounting surface is further provided with connecting ears for fixing to the vehicle body. There are multiple connecting ears, each located near the instrument panel mounting boss. Here, the connecting ears can be used to increase the local rigidity of the instrument panel mounting point and to partially fulfill the function of meeting pedestrian protection requirements.

[0019] Secondly, this application also provides a vehicle comprising a windshield, an air intake panel, a front panel, and a windshield reinforcement assembly according to any one of the first aspects. The air intake panel is disposed below the windshield; the windshield reinforcement assembly is disposed below the windshield and between the air intake panel and the front panel. Because this vehicle uses the windshield reinforcement assembly according to any one of the first aspects, it has the same technical advantages, namely, good sealing performance and simple structure.

[0020] In one possible implementation of this application, the air chamber panel is made of plastic. The air chamber panel has connecting holes on the side near the windshield crossbeam for screwing or snapping onto the windshield crossbeam via a connecting structure. For example, the air chamber panel can be integrally molded using injection molding. Using plastic for the air chamber panel reduces the number of parts, thereby improving vehicle assembly efficiency. Compared to sheet metal air chamber panels, plastic air chamber panels offer greater molding flexibility. Furthermore, the weight of plastic air chamber panels is significantly lower than that of sheet metal air chamber panels, reducing the overall weight of the vehicle and contributing to vehicle lightweighting, thus improving the vehicle's range. Moreover, the use of plastic for the air chamber panel facilitates screwing or snapping onto the windshield crossbeam via a connecting structure, making it easier to disassemble and repair the air chamber panel.

The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0037] This application provides a vehicle. It should be noted that the vehicle in this application can refer to large cars, small cars, special vehicles, etc. For example, according to the vehicle type, the car in this application embodiment can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles.

[0038] With the development of vehicle technology and the promotion of pedestrian protection requirements, people have higher demands for car safety and comfort. Among them, pedestrian protection requirements mainly simulate the collision between a pedestrian and a vehicle during the process of crossing the road. First, the pedestrian's lower leg collides with the front bumper or headlights. Then, the pedestrian will be propelled diagonally upwards towards the front hood, with the thigh colliding with the front bumper and hood. Finally, the pedestrian will fall down along the vehicle's surface, and the head will collide with the front surface of the vehicle (hood, fenders, windshield, windshield trim, A-pillar, etc.).

[0039] This application provides a vehicle, referring to... Figure 1 and Figure 7 The vehicle includes a windshield 4, an air chamber panel 2, a front wall panel 3, and a windshield reinforcement assembly 1. The air chamber panel 2 is located below the windshield 4; the windshield reinforcement assembly 1 is located below the windshield 4 and between the air chamber panel 2 and the front wall panel 3. This windshield reinforcement assembly 1 has the advantages of good sealing performance and simple structure.

[0040] This application provides a front windshield reinforcement assembly 1, referring to... Figure 1 , Figure 2 and Figure 3 The front windshield reinforcement assembly 1 is disposed between the air chamber panel 2 and the front wall panel 3. The front windshield reinforcement assembly 1 includes a windshield reinforcement member, an upper windshield crossbeam 12, and a lower windshield crossbeam 13. The upper windshield crossbeam 12 is located below the windshield reinforcement member; the upper windshield reinforcement member 11 and the lower windshield crossbeam 13 are both located above the front wall panel 3, and the three are sequentially overlapped along the sides in the vehicle width direction to form a cavity structure. The upper windshield crossbeam 12 has a first mounting surface 1211 and a second mounting surface 123 with a stepped transition. The first mounting surface 1211 has a connection structure for connecting to the air chamber panel 2. Here, referring to… Figure 2 The first mounting surface 1211 and the second mounting surface 123 are not at the same height, but are stepped together. For example, the first mounting surface 1211 is located on the lower left side of the second mounting surface 123. In addition, the first mounting surface 1211 is pressed and adhered to the air chamber plate 2 with a first seal 5; the second mounting surface 123 is pressed and adhered to the windshield 4 with a second seal 6.

[0041] When a vehicle collides with a pedestrian, the windshield reinforcement assembly 1 is typically the area where the pedestrian's head is most likely to come into contact. When a pedestrian hits the windshield, the impact is transmitted to the vehicle body structure around the windshield, such as the upper windshield beam 12. If the vehicle body structure around the windshield can deform upon impact, it can cushion the impact and reduce injury to the pedestrian. Therefore, the end of the upper windshield beam 12 away from the air chamber panel 2 is designated as a free end. The free end of the air chamber panel 2 has a certain gap with the instrument panel 8 assembly and the front wall panel 3 assembly in the length direction of the vehicle body to reduce the stiffness of the upper windshield beam 12 area, thereby creating a certain crumple zone when the vehicle collides with a pedestrian, thus reducing the injury to the pedestrian.

[0042] Furthermore, the design of the front windshield reinforcement 11, the lower front windshield crossbeam 13, and the front wall panel 3, which are sequentially overlapped along the side of the vehicle body to form a cavity structure, can significantly improve the strength of the front part of the vehicle, enhance the force transmission effect in frontal and side collisions, and thus improve the overall modal and torsional stiffness of the front of the vehicle, reducing the injury to pedestrians in the event of a collision. For example, when a pedestrian's head hits the windshield 4, the windshield 4 will transfer the impact force from the pedestrian's head to the upper front windshield crossbeam 12 connected to the windshield 4. Since the end of the upper front windshield crossbeam 12 away from the air chamber panel 2 is set as a free end, it can form a certain amount of crumple deformation, thereby absorbing energy. Alternatively, when a pedestrian hits the area around the windshield, the impact force is transferred to the windshield reinforcement 11 and the cavity structure formed by the windshield lower crossbeam 13 and the windshield reinforcement 11 connected to it, causing the cavity structure to be compressed and deformed into the space to absorb the impact energy and protect the pedestrian.

[0043] Moreover, compared to the cavity structure formed by the upper windshield crossbeam 12, the lower windshield crossbeam 13, and the windshield reinforcement 11, the location and structure of the front wall panel 3 are not easily altered. Therefore, only the structural design and layout of the windshield reinforcement 11 and the lower windshield crossbeam 13 need to be adjusted to easily form a cavity structure between them, making the structure of the windshield reinforcement assembly 1 simpler and easier to implement. It should be noted that the shape of the cavity structure is not limited; it can be square, elliptical, triangular, etc. Preferably, the windshield reinforcement 11, the lower windshield crossbeam 13, and the front wall panel 3 are sequentially overlapped along the width of the vehicle body to form a more stable triangular cavity structure.

[0044] Specifically, the windshield reinforcement 11 is disposed between the upper windshield crossbeam 12 and the lower windshield crossbeam 13. The end of the upper windshield crossbeam 12 near the air chamber panel 2 along the length of the vehicle body is connected to the air chamber panel 2, and the connection method is not limited, such as screw connection or welding. The end of the upper windshield crossbeam 12 away from the air chamber panel 2 is a free end. The free end of the air chamber panel 2 has a certain gap with the instrument panel 8 assembly and the front wall panel 3 assembly in the length of the vehicle body to reduce the stiffness of the area of ​​the upper windshield crossbeam 12, so that a certain crumple space is formed when the vehicle collides with a pedestrian, thereby reducing the injury to the pedestrian. Furthermore, the design of the front windshield reinforcement 11, the lower front windshield crossbeam 13, and the front wall panel 3 being sequentially overlapped along the side of the vehicle body to form a cavity structure can significantly improve the strength of the front part of the vehicle, enhance the force transmission effect of frontal and side collisions, thereby improving the overall modal and torsional stiffness of the front of the vehicle body and reducing the injury to pedestrians when the vehicle collides with pedestrians. Moreover, compared with the cavity structure composed of the upper front windshield crossbeam 12, the lower front windshield crossbeam 13, and the front windshield reinforcement 11, since the position and structure of the front wall panel 3 are not easy to change, it is only necessary to adjust the structural design and layout of the front windshield reinforcement 11 and the lower front windshield crossbeam 13 to easily form a cavity structure between the front windshield reinforcement 11, the lower front windshield crossbeam 13, and the front wall panel 3, making the structure of the front windshield reinforcement assembly 1 simpler and easier to implement.

[0045] Since the windshield reinforcement assembly 1 is located at the lower part of the windshield, it is an important component that supports the glass and connects the left and right side panels, the front wall panel 3, and the heater pressure chamber plate. The heater pressure chamber plate, which is connected to it, is also the main drainage structure at the front of the vehicle, operating in a relatively harsh environment. If the structure is not properly designed and the sealing effect is poor, water can easily enter the vehicle's engine compartment, instrument panel 8 assembly, and other components, leading to corrosion, leaks, and affecting vehicle quality and ride comfort. Therefore, in order to solve the problem of poor sealing effect, this application incorporates a first sealing element 5 and a second sealing element 6, respectively, between the first mounting surface 1211 and the air chamber plate 2, and between the second mounting surface 123 and the windshield 4. This means that two sealing structures are directly installed on the upper crossbeam 12 of the windshield, reducing water leakage from the air chamber and engine compartment. Furthermore, since both sealing structures are located on the upper crossbeam 12 of the windshield, the structural layout of the windshield reinforcement assembly 1 is simple and reasonable.

[0046] It should be noted that the positions of the first mounting surface 1211 and the second mounting surface 123 on the upper crossbeam 12 of the windshield are not limited, nor are their specific structures. For example, the first mounting surface 1211 and the second mounting surface 123 may be mounting bosses spaced apart on the outer wall of the upper crossbeam 12 of the windshield, or the first mounting surface 1211 and the second mounting surface 123 may be integrally formed on the outer wall of the upper crossbeam 12 of the windshield. Preferably, the first mounting surface 1211 and the second mounting surface 123 may be two mounting bosses with a stepped transition on the same side of the outer wall of the upper crossbeam 12 of the windshield. Here, a stepped transition means that the two mounting bosses have different heights along their extension direction. This facilitates the installation of the first sealing element 5 and the second sealing element 6 on the first mounting surface 1211 and the second mounting surface 123 respectively. This avoids interference between the first sealing element 5 and the second sealing element 6 when the end faces of the first mounting surface 1211 and the second mounting surface 123 are on the same plane.

[0047] Additionally, it should be noted that the air chamber panel 2 in this application typically refers to the heater pressure chamber panel assembly. Located above the front wall panel 3 and below the windshield 4, the heater pressure chamber panel assembly primarily functions to drain water from the vehicle and provide air conditioning intake. Structurally, it improves the vehicle's torsional rigidity. This structure also plays a crucial role in pedestrian protection during collisions, body modal analysis, and corrosion resistance. Because the heater pressure chamber panel structure is positioned between the windshield 4 and the front wall panel 3, a larger transition area is created between them. This allows liquid flowing down from the windshield 4 to collect on the heater pressure chamber panel structure, preventing it from flowing directly into the vehicle's front compartment. This improves the vehicle's ability to guide liquid flow and reduces the possibility of liquid entering the front compartment.

[0048] The connection structure for connecting the air chamber plate 2 on the first mounting surface 1211 is not limited. For example, the connection structure may be threaded holes provided on the end of the air chamber plate 2 near the first mounting surface 1211 and on the first mounting surface 1211, and the two can be detachably connected by bolts passing through the threaded holes on the air chamber plate 2 and the second mounting surface 123 in sequence; or the first mounting surface 1211 may be provided with a welding part, and the two can be welded together by welding. This application embodiment does not limit this.

[0049] In some embodiments, refer to Figure 1 , Figure 2 and Figure 3The end of the upper crossbeam 12 of the front windshield near the air chamber panel 2 has a first flange 121, and the end opposite to the first flange 121 has a second flange 122; wherein, the first mounting surface 1211 is disposed on the first flange 121, and the second flange 122 is pressed and fitted with the front wall panel 3 by a sound insulation component 7. In this design, a first flange 121 is formed at the end of the upper crossbeam 12 of the windshield near the air chamber panel 2, and a second flange 122 is formed at the end opposite to the first flange 121, that is, at the end of the upper crossbeam 12 of the windshield near the front wall panel 3. Preferably, the flange direction of the first flange 121 is opposite to that of the second flange 122. Here, the first flange 121 is directly formed on the upper crossbeam 12 of the windshield, which can increase the installation space on the upper crossbeam 12 of the windshield. Furthermore, the first mounting surface 1211 is set on the first flange 121, which facilitates the spacing between the first mounting surface 1211 and the second mounting surface 123, thereby facilitating the arrangement of the first sealing element 5 on the first mounting surface 1211. In addition, the design of the sound insulation element 7 being pressed tightly between the second flange 122 and the front wall panel 3 can improve the overall vehicle's leak-proof, vibration isolation, and noise reduction performance.

[0050] It should be noted that the sound insulation component 7 here has a sheet-like structure to facilitate better fit between the front wall panel 3 and the upper crossbeam 12 of the windshield. The first flange 121 and the second flange 122 at opposite ends of the upper crossbeam 12 of the windshield make the cross-sectional shape of the entire upper crossbeam 12 of the windshield in the direction perpendicular to the width of the vehicle body Z-shaped. This effectively increases the coverage area of ​​the cabin sound insulation component 7 fitted to the flange structure of the front wall panel 3 and the upper crossbeam 12 of the windshield compared to when the upper crossbeam 12 of the windshield has no flange structure, thus improving the overall vehicle's leak-proof, vibration isolation, and noise reduction performance. Specifically, the Z-shaped cross-section of the upper crossbeam 12 of the windshield allows for the addition of flanges to the cabin sound insulation component 7, and allows the mounting point of the sound insulation component 7 to be arranged on the upper crossbeam 12 of the windshield and extend to the windshield 4, thereby increasing the coverage area of ​​the sound insulation component 7 in the front wall panel 3 area and improving the sealing, sound insulation, and noise reduction effects.

[0051] In some embodiments, refer to Figures 3-6The first mounting surface 1211 is also provided with multiple first mounting bosses 1211a, each with a mounting hole 1211b. The connection structure is the mounting hole 1211b, which is used to screw or snap the upper crossbeam 12 of the windshield to the air chamber plate 2 with fasteners. The reason for providing multiple first mounting bosses 1211a on the first mounting surface 1211, and connecting them to the upper crossbeam 12 of the windshield via the mounting holes 1211b, instead of directly opening mounting holes 1211b on the first mounting surface 1211, is to facilitate the installation of the first sealing element 5 on the first mounting surface 1211. Specifically, the presence of the first mounting boss 1211a can, on the one hand, avoid the installation of the first seal 5; on the other hand, since there is a certain distance difference between the end face of the first mounting boss 1211a away from the first mounting surface 1211 and the first mounting surface 1211, that is, an arrangement space for placing the first seal 5 is formed between the end face of the first mounting boss 1211a away from the first mounting surface 1211 and the first mounting surface 1211, it is convenient for the first seal 5 to fit between the first mounting surface 1211 and the air chamber plate 2.

[0052] In this embodiment, the air chamber panel 2 and the upper crossbeam 12 of the windshield can be fixedly connected by slots and clips, or by bolts, or by riveting, etc., and this application does not limit the connection. Preferably, this application uses screw connection or clip connection, which is convenient for disassembly and assembly and has a simple structure.

[0053] In some embodiments, refer to Figures 3-6 The second mounting surface 123 has multiple second mounting bosses 1231 facing the windshield 4, and the second sealing element 6 is disposed on the second mounting bosses 1231. In this way, based on the first seal formed between the windshield upper crossbeam 12 and the air chamber plate 2, the second sealing element 6 disposed on the second mounting bosses 1231 forms a sealing structure between the windshield 4 and the windshield reinforcement assembly 1, which can prevent liquid flowing down from the windshield 4 from entering the vehicle engine compartment through the windshield upper crossbeam 12.

[0054] Reference Figures 3-6The second flange 122 has a sound insulation mounting surface 1221 and a sound insulation mounting recess 1222. Multiple sound insulation components 7 are provided, with at least two mounting surfaces 1221 respectively located at both ends of the upper crossbeam 12 of the front windshield along its length. Multiple sound insulation mounting recesses 1222 are spaced apart along the extension direction of the upper crossbeam 12 of the front windshield, used to install the sound insulation components 7 between the second flange 122 and the front wall panel 3. The placement of the sound insulation mounting recesses 1222 helps to avoid obstructing the installation of the sound insulation components 7. In addition, since there is a certain distance difference between the end face of the sound insulation mounting recess 1222 that is away from the sound insulation mounting surface 1221 and the sound insulation mounting surface 1221, that is, an arrangement space for placing the sound insulation component 7 is formed between the end face of the sound insulation mounting recess 1222 that is away from the sound insulation mounting surface 1221 and the sound insulation mounting surface 1221, it is convenient to fit the sound insulation component 7 between the sound insulation mounting surface 1221 and the front wall panel 3.

[0055] In some embodiments, refer to Figures 3-6 Both the mounting surface 1221 and the mounting recess 1222 of the sound insulation component are provided with sound insulation component snap-fit ​​holes 1223, and the opening direction of the sound insulation component snap-fit ​​holes 1223 faces the height direction of the vehicle body. The sound insulation component snap-fit ​​holes 1223 are used to snap the snap-fit ​​part of the sound insulation component 7 into the sound insulation component snap-fit ​​holes 1223, and the sound insulation component 7 can be pressed and fitted against the front wall panel 3 along the extension direction of the front wall panel 3 through multiple sound insulation component mounting recesses 1222. Here, the design of the sound insulation component 7 snapping into the sound insulation component snap-fit ​​holes 1223, compared with the design of installing the sound insulation component 7 on the front wall panel 3 along the length direction of the vehicle body by using mounting studs, can greatly increase the coverage area of ​​the sound insulation component 7 on the front wall panel 3, thereby improving the sealing, sound insulation and noise reduction effect of the entire vehicle.

[0056] Continue, refer to Figures 3-6The upper crossbeam 12 of the windshield is also provided with a third mounting surface 124, which is located between the first flange 121 and the second flange 122. The third mounting surface 124 has multiple instrument panel mounting surfaces 1241 and multiple instrument panel mounting bosses 1242 for mounting instrument components. This improves the integration of the upper crossbeam 12 of the windshield, allowing the installation of multiple functional components to be integrated on the upper crossbeam 12 of the windshield. The instrument panel mounting surfaces 1241 and instrument panel mounting bosses 1242 for mounting instrument components are located on the upper crossbeam 12 of the windshield because the upper crossbeam 12 of the windshield has at least three sealing structures, namely at least three sealing structures between the upper crossbeam 12 of the windshield and the air chamber panel 2, the windshield 4, and the front wall panel 3. This allows the instrument panel mounting surfaces 1241 and the multiple instrument panel mounting bosses 1242 to provide rust and leakage protection for the instrument components in the passenger compartment. In addition, since the upper crossbeam 12 of the windshield and the instrument panel 8 assembly are at approximately the same height along the vehicle body height direction, it is convenient to align and install the instrument panel mounting surface 1241 and the instrument panel mounting boss 1242 on it.

[0057] In some embodiments, refer to Figures 3-6 The third mounting surface 124 is also provided with connecting ears 1243 for fixing to the vehicle body. There are multiple connecting ears 1243, preferably two, and each connecting ear 1243 is set near the instrument mounting boss. Here, the setting of connecting ears 1243 can be used to improve the local rigidity of the mounting point of the instrument panel 8, and to undertake part of the function of meeting pedestrian protection requirements.

[0058] In some embodiments, refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 The air chamber panel 2 is made of plastic. It has connecting holes on the side near the windshield crossbeam 12 for screwing or snapping onto the crossbeam 12 via a connecting structure. For example, the air chamber panel 2 can be integrally molded using injection molding. Using plastic for the air chamber panel reduces the number of parts, thus improving vehicle assembly efficiency. Compared to sheet metal air chamber panels, plastic air chamber panels offer greater molding flexibility. Furthermore, the weight of plastic air chamber panels is significantly lower than that of sheet metal air chamber panels, reducing the overall weight of the vehicle and contributing to weight reduction, thereby improving the vehicle's range. Moreover, the plastic material of the air chamber panel 2 facilitates screwing or snapping onto the windshield crossbeam 12 via a connecting structure, making it easier to disassemble and repair the air chamber panel 2.
