Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and more specifically, to a vehicle hood assembly and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry and increasingly stringent vehicle safety regulations, pedestrian protection has become a crucial factor that cannot be ignored in vehicle design. As domestically produced vehicles gain a larger share of the international market, their pedestrian protection functions need to meet both domestic field-of-view requirements and international market demands.

[0003] Specifically, the vehicle hood mainly consists of an outer panel, an inner panel, and internal structural components such as hinges and latches. To achieve lightweight design, the hood primarily uses a one-piece inner panel, ensuring sufficient rigidity, dent resistance, and modal performance. However, the vehicle hood is a crucial area for pedestrian safety, requiring that the stiffness of the parts where a pedestrian's head may come into contact with the hood be as low as possible.

[0004] In other words, existing technologies for vehicle hoods present a challenge in balancing pedestrian protection and dent resistance.

[0005] There is currently no good solution to the above problems. Summary of the Invention

[0007] According to one aspect of the present application, a vehicle hood assembly is provided, including: an outer hood panel, an inner hood panel, and an outer panel reinforcing plate assembly, wherein the outer panel reinforcing plate assembly is located between the outer hood panel and the inner hood panel; wherein the outer panel reinforcing plate assembly includes a plurality of middle and outer panel reinforcing plates, the plurality of middle and outer panel reinforcing plates are symmetrically arranged in a pedestrian protection area opened in the middle of the inner hood panel, and the middle and outer panel reinforcing plates are connected to the inner hood panel.

[0008] Furthermore, the outer panel reinforcement assembly also includes a front outer panel reinforcement plate, a rear outer panel reinforcement plate, and multiple side outer panel reinforcement plates; the front hood inner panel also includes a front beam area, a rear beam area, and two side beam areas located around the pedestrian protection area, with the two side beam areas symmetrically located on both sides of the pedestrian protection area; multiple side outer panel reinforcement plates are symmetrically located in each side beam area, with the front outer panel reinforcement plate connected to the front beam area and the rear outer panel reinforcement plate connected to the rear beam area.

[0009] Furthermore, the vehicle hood assembly also includes a hinge mounting reinforcement plate and a lock hook mounting reinforcement plate, both of which are located between the outer hood panel and the inner hood panel. At least one of the outer hood panel, the inner hood panel, the front outer panel reinforcement plate, the rear outer panel reinforcement plate, and the side outer panel reinforcement plate is made of aluminum alloy.

[0010] Furthermore, at least one of the inner and outer plate reinforcing plates, hinge mounting reinforcing plates, and lock hook mounting reinforcing plates is made of steel.

[0011] Furthermore, at least one of the following components—the outer front hood panel, the inner front hood panel, the front outer panel reinforcement plate, the rear outer panel reinforcement plate, the side outer panel reinforcement plate, the middle outer panel reinforcement plate, the hinge mounting reinforcement plate, and the lock hook mounting reinforcement plate—has a sheet thickness between 0.5 mm and 1.5 mm.

[0012] Furthermore, the aluminum alloy thickness of at least one of the outer and inner front hood panels is between 0.8 mm and 1 mm.

[0013] Furthermore, the aluminum alloy thickness of at least one of the front outer panel reinforcement plate, the rear outer panel reinforcement plate, and the side outer panel reinforcement plate is between 0.7 mm and 0.9 mm.

[0014] Furthermore, the steel thickness of at least one of the inner and outer reinforcing plates is between 0.9 mm and 1.1 mm.

[0015] Furthermore, the steel thickness of at least one of the hinge mounting reinforcement plate and the lock hook mounting reinforcement plate is between 1.1 mm and 1.2 mm.

[0016] Furthermore, at least one of the side outer plate reinforcement plate, middle outer plate reinforcement plate, front outer plate reinforcement plate, and rear outer plate reinforcement plate has a ring beam structure and is provided with multiple overlapping edges to connect with the inner plate of the front hatch.

[0017] Furthermore, the ring beam structure has multiple weight-reduction holes embedded in it, and multiple concave adhesive grooves are provided on the ring beam structure. At least one of the side outer plate reinforcement plate, middle outer plate reinforcement plate, front outer plate reinforcement plate, and rear outer plate reinforcement plate is glued to the inner side of the front hatch outer plate through the adhesive grooves.

[0018] Furthermore, the two side beam areas are the left beam area and the right beam area, and at least one of the left beam area and the right beam area is provided with four side outer plate reinforcement plates.

[0019] Furthermore, the vehicle hood assembly also includes two hinge mounting reinforcement plates, which are respectively located in the two side beam areas.

[0020] Furthermore, the vehicle hood assembly also includes a lock hook mounting reinforcement plate, with lock hooks provided on the inner panel of the hood, and the lock hook mounting reinforcement plate securing the lock hooks.

[0021] According to another aspect of the embodiments of this application, a vehicle is also provided, the vehicle including the above-described vehicle hood assembly.

[0022] In this embodiment, a pedestrian protection area is created by establishing an outer panel reinforcement assembly between the outer and inner panels of the hood. Specifically, an independent middle and outer panel reinforcement is provided in the pedestrian protection area. This ensures the dent resistance of the pedestrian protection area while allowing the middle and outer panel reinforcement to be connected separately to the inner panel of the hood. A buffer space is maintained between the middle and outer panel reinforcement and the outer panel of the hood, thus avoiding the stiffness enhancement effect of the integrated outer panel reinforcement. This weakens the stiffness of the middle part of the hood, thereby simultaneously achieving the technical effect of ensuring dent resistance and enhancing pedestrian protection buffer performance. This solves the technical problem in the prior art that it is difficult to balance pedestrian protection and dent resistance in vehicle hoods. Attached Figure Description

Detailed Implementation

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0035] like Figures 1 to 7As shown in the embodiment of this application, a vehicle hood assembly is provided, including an outer hood panel 10, an inner hood panel 20, and an outer panel reinforcing plate assembly 30. The outer panel reinforcing plate assembly 30 is located between the outer hood panel 10 and the inner hood panel 20. The outer panel reinforcing plate assembly 30 includes a plurality of middle and outer panel reinforcing plates 31, which are symmetrically arranged within a pedestrian protection area 21 opened in the middle of the inner hood panel 20. The middle and outer panel reinforcing plates 31 are connected to the inner hood panel 20.

[0036] In this embodiment, a pedestrian protection area 21 is created by establishing an outer panel reinforcement assembly 30 between the outer panel 10 and the inner panel 20 of the hood. In particular, an independent middle and outer panel reinforcement 31 is set in the pedestrian protection area 21. On the one hand, the anti-dent performance of the pedestrian protection area 21 is guaranteed. On the other hand, the middle and outer panel reinforcement 31 is independently connected to the inner panel 20 of the hood, and a buffer space is reserved between the middle and outer panel reinforcement 31 and the outer panel 10 of the hood. It is not affected by the rigidity enhancement effect of the integrated outer panel reinforcement, which weakens the rigidity of the middle part of the hood. Thus, the technical effect of ensuring anti-dent performance and enhancing pedestrian protection buffer performance is achieved at the same time. This solves the technical problem in the prior art that it is difficult to balance pedestrian protection and anti-dent performance of vehicle hoods.

[0037] In such Figure 2 In the specific embodiment shown, the outer panel reinforcement assembly 30 also includes a front outer panel reinforcement 32, a rear outer panel reinforcement 33, and multiple side outer panel reinforcements; the front hatch inner panel 20 also includes a front beam region 22, a rear beam region 23, and two side beam regions disposed around the pedestrian protection area 21, with the two side beam regions symmetrically disposed on both sides of the pedestrian protection area 21; multiple side outer panel reinforcements are symmetrically disposed in each side beam region, with the front outer panel reinforcement 32 connected to the front beam region 22 and the rear outer panel reinforcement 33 connected to the rear beam region 23.

[0038] The front outer panel reinforcement plate 32 is located in the front beam area 22 at the front end of the inner hood panel 20, and the rear outer panel reinforcement plate 33 is located in the rear beam area 23 at the rear end of the inner hood panel 20. The side outer panel reinforcement plates are symmetrically arranged in the two side beam areas. Here, "front end" refers to the position of the inner hood panel 20 relatively far from the driver's seat, and "rear end" refers to the position of the inner hood panel 20 relatively close to the driver's seat. The side beam areas refer to the positions of the inner hood panel 20 on both sides of the vehicle body. In other words, the front outer panel reinforcement plate 32 and the rear outer panel reinforcement plate 33 can better support the front and rear ends of the hood, improving the overall stability of the hood. The symmetrical arrangement of the side outer panel reinforcement plates ensures the uniform distribution of the hood in the lateral direction, avoiding structural imbalance caused by unilateral reinforcement.

[0039] Specifically, the pedestrian protection zone 21 is located at the center of the inner panel 20 of the front hatch, while the outer front beam area 22, rear beam area 23 and two side beam areas form a ring, which not only breaks down the stiffness distribution of the entire front hatch, but also provides the necessary support and buffer space for the pedestrian protection zone 21, effectively disperses and absorbs collision energy, reduces the injury to the pedestrian's head when hit, and improves the pedestrian protection performance of the front hatch.

[0040] The two side beam areas are designated as left beam area 24 and right beam area 25, with at least one of them equipped with four side outer panel reinforcement plates. In the event of a collision with a pedestrian, the pedestrian's head may impact the hood from different angles. Therefore, by evenly distributing four side outer panel reinforcement plates in left beam area 24 and right beam area 25, the hood can provide buffer space and energy absorption capacity at the side edges of the vehicle body, thereby protecting the pedestrian's head and reducing collision injuries.

[0041] The modal values ​​and stiffness of the hood are crucial for reducing vehicle vibration and noise during driving. The installation of side panel reinforcements not only adjusts the local stiffness of the hood, but also optimizes the modal values ​​of the entire hood by adjusting the position of the side panel reinforcements. This avoids resonance with the excitation frequency during vehicle operation, reduces vibration and noise, and improves driving comfort. Preferably, both the left beam region 24 and the right beam region 25 are provided with four side outer plate reinforcing plates. For example, the four side outer plate reinforcing plates of the left beam region 24 are the first left outer plate reinforcing plate 341, the second left outer plate reinforcing plate 342, the third left outer plate reinforcing plate 343, and the fourth left outer plate reinforcing plate 344. The first left outer plate reinforcing plate 341 to the fourth left outer plate reinforcing plate 344 are distributed along the left beam region 24 according to pedestrian protection and modal requirements. The four side outer plate reinforcing plates of the right beam region 25 are the first right outer plate reinforcing plate 351, the second right outer plate reinforcing plate 352, the third right outer plate reinforcing plate 353, and the fourth right outer plate reinforcing plate 354.

[0042] It should be noted that the "left" and "right" mentioned above correspond to... Figure 3 The relative positions of the left and right sides of the upper body. The dispersed arrangement of the aforementioned side outer panel reinforcement plates allows for greater design flexibility by adjusting the specific position and number of the reinforcement plates to meet different pedestrian protection score requirements, dent resistance performance, and connection strength with the vehicle body, depending on the vehicle model and styling requirements.

[0043] In such Figures 4 to 6 In the specific embodiments shown, please refer to the following: Figure 4 As shown in the diagram, the inner and outer reinforcing plates 31, such as... Figure 5 The front outer panel reinforcement plate 32 shown is as follows: Figure 6The rear outer panel reinforcement plate 33 and the side outer panel reinforcement plates (not shown) all have annular beam structures 41. These annular beam structures 41 are closed rings, which, compared to straight or open structures, provide more stable support under external forces, thus improving the dent resistance of the front hatch without increasing material thickness. Simultaneously, in non-stressed or less critical areas, each outer panel reinforcement plate has embedded weight-reduction holes 43. The number of weight-reduction holes 43 varies from one to several depending on the shape and thickness of each reinforcement plate, ensuring structural strength while minimizing material usage and meeting the lightweight requirements of the front hatch.

[0044] In addition, the side outer plate reinforcement plate, middle outer plate reinforcement plate 31, front outer plate reinforcement plate 32, and rear outer plate reinforcement plate 33 are also provided with multiple overlapping edges 42 to connect with the inner front hatch panel 20. The overlapping edges 42 are protruding edges extending from the edges of the aforementioned outer plate reinforcement plates. The overlapping edges 42 provide a wider bonding or welding area, thereby improving the connection strength between the aforementioned outer plate reinforcement plates and the inner front hatch panel 20, ensuring the structural integrity of the front hatch under complex working conditions. At the same time, multiple concave adhesive grooves 44 are provided on the annular beam structure 41. The adhesive grooves 44 are opened between the weight reduction holes 43 and the edges of the aforementioned outer plate reinforcement plates, so that the aforementioned outer plate reinforcement plates are glued to the inner side of the front hatch outer panel 10 through the adhesive grooves 44. This setting of adhesive grooves 44 not only fixes the connection between the aforementioned outer plate reinforcement plates and the front hatch outer panel 10, but also generates plastic deformation during pedestrian collisions, providing buffer and energy absorption space.

[0045] like Figure 2 and Figure 4 The middle and outer plate reinforcing plates 31 shown are preferably two in number, including a left middle and outer plate reinforcing plate 311 and a right middle and outer plate reinforcing plate 312 symmetrically arranged.

[0046] Specifically, since some of the side outer plate reinforcing plates are relatively narrow, the weight reduction holes 43 may not be provided on the side outer plate reinforcing plates, just as... Figure 7 As shown, the outer side plate reinforcement plate is provided with multiple recessed glue application grooves 44 and overlapping edges 42.

[0047] In such Figure 2 In the specific implementation shown, in order to meet the functional requirements of the vehicle hood assembly, the vehicle hood assembly also includes a hinge mounting reinforcement plate 36 and a lock hook mounting reinforcement plate 37, both of which are located between the outer hood panel 10 and the inner hood panel 20.

[0048] It should be noted that the hinge connects the hood to the vehicle body and bears the stress generated when the hood is opened and closed. By setting hinge mounting reinforcement plates 36 in the two side beam areas between the outer hood panel 10 and the inner hood panel 20, the structural rigidity of the hinge mounting area can be significantly enhanced, preventing deformation or damage caused by stress concentration during long-term use, and also avoiding wear and noise caused by unstable hinge position. Specifically, there are two hinge mounting reinforcement plates 36, symmetrically arranged in the left beam area 24 and the right beam area 25.

[0049] It should be noted that the inner panel 20 of the hood is equipped with a locking hook 45, and the locking hook mounting reinforcement plate 37 can enhance the locking engagement between the locking hook 45 and the vehicle body. The locking hook 45 will withstand significant tensile and shear forces when locked. The locking hook mounting reinforcement plate 37 helps to evenly distribute these forces across the inner panel 20 of the hood, reducing the risk of excessive local stress leading to locking hook 45 failure, ensuring the hood is securely locked during vehicle operation, and preventing accidental opening.

[0050] To achieve a lightweight design for the vehicle's hood assembly and ensure appropriate rigidity, at least one of the following components—outer hood panel 10, inner hood panel 20, front outer panel reinforcing plate 32, rear outer panel reinforcing plate 33, and side outer panel reinforcing plate—is made of aluminum alloy; at least one of the following components—middle outer panel reinforcing plate 31, hinge mounting reinforcing plate 36, and lock hook mounting reinforcing plate 37—is made of steel; and the thickness of at least one of the following components—outer hood panel 10, inner hood panel 20, front outer panel reinforcing plate 32, rear outer panel reinforcing plate 33, side outer panel reinforcing plate, middle outer panel reinforcing plate 31, hinge mounting reinforcing plate 36, and lock hook mounting reinforcing plate 37—is between 0.5 mm and 1.5 mm.

[0051] Preferably, the aluminum alloy thickness of at least one of the front hatch outer panel 10 and the front hatch inner panel 20 is between 0.8 mm and 1 mm; the aluminum alloy thickness of at least one of the front outer panel reinforcing plate 32, the rear outer panel reinforcing plate 33 and the side outer panel reinforcing plate is between 0.7 mm and 0.9 mm; the steel thickness of at least one of the middle outer panel reinforcing plate 31 is between 0.9 mm and 1.1 mm; and the steel thickness of at least one of the hinge mounting reinforcing plate 36 and the lock hook mounting reinforcing plate 37 is between 1.1 mm and 1.2 mm.

[0052] More preferably, in a specific embodiment not shown, the shortest distance between the outer front hood panel 10 and the engine compartment is 50mm, resulting in insufficient headroom for pedestrians. In this embodiment, the aluminum alloy thickness of the outer front hood panel 10 and the inner front hood panel 20 is set to 0.9mm; the aluminum alloy thickness of the front outer panel reinforcement plate 32, the rear outer panel reinforcement plate 33, and the side outer panel reinforcement plate is set to 0.8mm; the steel thickness of the middle outer panel reinforcement plate 31 is set to 1mm; and the steel thickness of the hinge mounting reinforcement plate 36 and the lock hook mounting reinforcement plate 37 is set to 1.2mm. In particular, in the pedestrian protection area 21, the middle outer panel reinforcement plate 31 is made of steel with a thickness of 1mm. Utilizing the high elastic modulus of the steel plate, sufficient cushioning can be provided when a pedestrian's head hits the outer front hood panel 10, preventing the head from impacting hard points such as the engine.

[0053] This application also provides a vehicle including the aforementioned vehicle hood assembly. The vehicle, including the aforementioned vehicle hood assembly, achieves the technical effect of simultaneously ensuring dent resistance and enhancing pedestrian protection buffer performance by setting independent middle and outer reinforcing plates in the pedestrian protection area. This is achieved on the one hand, ensuring the dent resistance performance of the pedestrian protection area, and on the other hand, weakening the effect of the central stiffness of the hood.

[0054] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
