DETAILED DESCRIPTION

[0055] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0056] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0058] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed or detachable connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention.

[0059] The present invention discloses an engine hood inner panel assembly and a corresponding engine hood comprising the inner panel assembly and an outer panel, wherein a hinge connecting arm assembly for fixing the engine hood is connected to the engine hood;

[0060] A lock reinforcement plate 2, an outer panel reinforcement plate 4 and a hinge reinforcement plate 3 for supporting the hood structure are fixed between the inner panel assembly and the outer panel, which not only strengthens the support of the hood space, but also strengthens the connection strength of supporting components such as the hinge and the hood locking structure.

[0061] The hood is made of aluminum alloy. The outer panel is converted from 0.7mm steel to 0.95mm aluminum, the inner panel is converted from 0.55mm steel to 0.8mm aluminum, the lock reinforcement plate 2 is 1.2mm aluminum, the outer panel reinforcement plate 4 is 1.2mm aluminum, and the hinge reinforcement plate 3 is 1.5mm aluminum. While significantly reducing the weight of the hood, CAE simulations and actual testing have shown that its rigidity still meets the requirements of the hood assembly performance.

[0062] In order to further reduce weight and increase structural strength, the inner panel 1 is provided with a plurality of first weight-reducing holes 104; the first weight-reducing holes 104 are opened in the inner panel 1 area between the lock reinforcement plate 2, the outer panel reinforcement plate 4 and the hinge reinforcement plate 3;

[0063] A supporting flange structure is provided on the inner plate 1 surrounding the outer periphery of the first weight-reducing hole 104, and a connecting strip is provided on one side of the supporting flange structure close to the lock reinforcement plate 2, the outer plate reinforcement plate 4 and the hinge reinforcement plate 3. The connecting strip cooperates with the first connecting part 205, the overlapping part 301 and the fifth connecting part 407 to fix the lock reinforcement plate 2, the hinge reinforcement plate 3 and the outer plate reinforcement plate 4.

[0064] In one embodiment, as shown in Figure 2, there are seven first lightening holes 104. Each first lightening hole 104 is coated with glue in a full circle, evenly distributed across the opening of the first lightening hole 104. The support glue provided by the raised first lightening holes 104 connects the inner and outer panels. This not only ensures more uniform application of glue, effectively supporting the inner and outer panel cavities, but also supports the space between the inner and outer panels in conjunction with the various reinforcement panels, ensuring that there are support points for the outer panel within a 200mm diameter range. This significantly improves the overall stiffness of the hood and the first-order NVH mode.

[0065] The support flange structure in the first weight-reducing hole 104 at least includes a first support flange structure 101 and an outer plate reinforcement plate connecting strip 1011 arranged close to the outer plate reinforcement plate 4, wherein the outer plate reinforcement plate connecting strip 1011 is arranged around the edge of the first support flange structure 101;

[0066] The support flange structure in the first weight-reducing hole 104 at least includes a second support flange structure 102 and a hinge reinforcement plate connecting strip 1021 arranged close to the hinge reinforcement plate 3, wherein the hinge reinforcement plate connecting strip 1021 is arranged around the edge of the second support flange structure 102;

[0067] The support flange structure in the first weight-reducing hole 104 includes at least a third support flange structure 103 and a lock reinforcement plate connecting strip 1031 provided close to the lock reinforcement plate 2, wherein the lock reinforcement plate connecting strip 1031 is provided around the edge of the third support flange structure 103;

[0068] The lock reinforcement plate connecting strip 1031 and the outer plate reinforcement plate connecting strip 1011 are continuous protruding structures, surrounding the periphery of at least five first weight-reducing holes 104 .

[0069] Compared to traditional steel hoods, the engine hood of this invention can reduce weight by approximately 30% to 40%. This reduced vehicle weight improves fuel economy, is more energy-efficient and environmentally friendly, and also enhances vehicle power performance. Aluminum has better thermal conductivity than traditional steel, facilitating heat dissipation within the engine compartment. Furthermore, aluminum hoods offer better corrosion resistance than steel hoods.

[0070] Example 1

[0071] As shown in Figure 1, this embodiment describes an engine hood inner panel assembly, which includes an inner panel 1, a lock reinforcement plate 2, an outer panel reinforcement plate 4, and a hinge reinforcement plate 3. In this embodiment, the inner panel 1 is formed by integral stamping, while the lock reinforcement plate 2, outer panel reinforcement plate 4, and hinge reinforcement plate 3 are independent components that are fixed to corresponding positions on the inner panel 1 through methods such as spot welding. Simultaneously, a certain number of standard components, such as rivet nuts and rivet bolts, are riveted to the lock reinforcement plate 2, outer panel reinforcement plate 4, and hinge reinforcement plate 3, depending on the specific assembly components to ensure local rigidity at the fixing points.

[0072] Specifically, the lock reinforcement plate 2 is connected to the upper surface of the first edge of the inner panel 1; the lock reinforcement plate 2 is installed at the corresponding position of the inner panel 1 and the engine hood locking mechanism, and on the symmetry line of the inner panel 1, the lock reinforcement plate 2 is provided with a long strip assembly hole that cooperates with the engine hood locking mechanism; preferably, the lock reinforcement plate 2 is installed near the first edge of the inner panel 1 at the front of the vehicle, extends along the width direction of the first edge, and is symmetrically arranged about the symmetry line of the inner panel 1.

The first connecting portion 205 is an L-shaped sheet structure, and the first connecting portion 205 and the upper surface of the inner panel 1 are both provided with connecting holes.

[0082] In order to facilitate the assembly of the lock reinforcement plate 2 and the inner plate 1 and improve the structural performance, a lock reinforcement plate support and limit portion 106 and a first support foot positioning portion 105 are provided at positions corresponding to the inner plate 1 and the lock reinforcement plate 2; the lock reinforcement plate support and limit portion 106 is long and strip-shaped and protrudes on the inner plate 1; the lock reinforcement plate body 204 is buckled on the lock reinforcement plate support and limit portion 106.

The first support leg 202 and the second support leg 203 are fixedly connected to the first support leg positioning portion 105 .

[0084] During assembly, the lower side surface of the lock reinforcement plate body 204 is buckled along the lock reinforcement plate support limit portion 106, and then the first support leg 202 and the second support leg 203 are respectively fitted with the two first support leg positioning portions 105, and the first support leg positioning portion 105 has an approximately U-shaped fitting surface, and the support leg is fitted and fixed to the support leg positioning portion by spot welding or riveting; on the one hand, the U-shaped fitting increases the force-bearing area, and also has a good structural support effect.

[0085] Part of the first connection portion 205 is fixed to the lock reinforcement plate connection strip 1031, and another part of the first connection portion 205 is directly fixed to the inner plate 1. The second connection portion 206 is fixed to the outer plate through supporting glue, thereby fixing the lock reinforcement plate 2 between the inner and outer plates.

The hinge reinforcement plate 3 is integrally stamped and formed. The hinge reinforcement plate support foot 302 is recessed on one side of the lock reinforcement plate 2. The overlap portion 301 is protruded from the lock reinforcement plate 2 and is arranged diagonally to the hinge reinforcement plate support foot 302. The hinge reinforcement plate support foot 302 is surrounded by a raised skirt structure. The overlap edge 303 is located at the edge of the lock reinforcement plate 2 in close proximity to the hinge reinforcement plate support foot 302.

The lower surface of the overlapping portion 301 is attached to the hinge reinforcement plate connecting strip 1021 of the inner panel 1 and fixed, while the upper surface is fixed to the outer panel via supporting glue. The hinge reinforcement plate 3 has an additional glue-coated point for connection with the outer panel, which improves the outer panel's dent resistance and the localized hinge fixing point stiffness. The stepped design and extension of the hinge reinforcement plate 3 along its length significantly improves torsional stiffness and modal properties.
