[0034] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0035] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0036] The hood assembly, located at the very front and top of the vehicle, must not only meet aesthetic requirements but also structural strength and crumple zone performance requirements. During vehicle use, the perimeter, front, and central areas of the hood assembly are high-pressure zones. Deformation and squeaking noises caused by pressure on these areas can negatively impact the driving experience. However, while meeting lightweight requirements, the hood assembly must also ensure structural strength, achieving a balance between dent resistance and crumple zone protection.

[0037] This application provides an inner panel for an engine hood. Figure 1 This is a schematic diagram of the structure of an inner panel of an engine hood according to an exemplary embodiment of this application. Figure 2 This is a schematic diagram of the structure of an inner panel body in an exemplary embodiment of this application, as shown below. Figure 1 , Figure 2 As shown, the inner panel 1 of the engine hood includes an inner panel body 11 and an outer panel support plate 12. In the length direction, the inner panel body 11 includes a supporting front end 111, a supporting middle portion 112, and a mounting section 113 located between the supporting front end 111 and the supporting middle portion 112. The outer panel support plate 12 is assembled to the mounting section 113. The supporting middle portion 112 includes at least two supporting vertical beams 1121 distributed along the width direction. The supporting vertical beams 1121 extend along the length direction, and a first hollow area 1122 is formed between two adjacent supporting vertical beams 1121.

[0038] The aforementioned inner panel body 11 forms a support structure for the outer panel 21 at the support front end, support middle and the outer panel support plate 12 located between the support front end and support middle. The support middle 112 forms a beamless support effect through the support vertical beam 1121 and the first hollow area 1122. While ensuring the overall strength of the inner panel body 11, it helps to achieve the lightweighting of the engine hood inner panel 1 and the crumple protection for pedestrians in collision scenarios.

[0039] It should be noted that the aforementioned length direction can be the direction parallel to the length of the vehicle after the inner panel 1 of the hood is assembled into the vehicle, and the width direction can be the direction parallel to the width of the vehicle after the inner panel 1 of the hood is assembled into the vehicle. Figure 1 A dashed line can represent the length direction, and a dotted line can represent the width direction.

[0040] In some embodiments, the support beam 1121 is provided with at least one first weakening hole 1125. By weakening the rigidity of the support beam 1121 through the first weakening hole 1125, it helps the support beam 1121 to have a collapse effect under impact, thus avoiding excessive injury to pedestrians.

[0041] The aforementioned supporting vertical beam 1121 may be provided with a plurality of first weakening holes 1125, which may be distributed along the vertical extension direction of the supporting vertical beam 1121. For example, the supporting vertical beam 1121 may be provided with three first weakening holes 1125, which are respectively located at the top, middle and bottom of the supporting vertical beam 1121 in the length direction to achieve the desired weakening effect.

[0042] In some embodiments, such as Figure 3 As shown, the supporting middle section 112 includes a central region and an edge region surrounding the central region. The supporting vertical beam 1121 is located in the central region, and the edge region includes multiple stacked structures 1123 spaced apart. Each stacked structure 1123 has a second weakening hole 1124. The second weakening hole 1124 located in the edge region weakens the load while satisfying the overall bending resistance of the middle section, reducing weight and cost, and achieving a balance between the robust dent resistance of the engine hood and pedestrian protection requirements. The stacked structure 1123 can be a stepped structure formed by the stacked structure in the edge region. The second weakening hole 1124, based on the stacked structure 1123, can reduce the impact of the hole position on the robust dent resistance of the engine hood by utilizing the stepped multi-layer structure, while also providing anti-collision and crumple resistance.

[0043] In the above embodiments, there may be two, three, or more support beams 1121, and this application does not limit this. The appropriate number of support beams 1121 can be selected based on the structural dimensions of the support center 112 of the inner plate body 11, the dimensions of the first hollow area 1122, and the required width of the support beams 1121. The aforementioned second weakening holes 1124 can be evenly distributed circumferentially along the edge region, and the number of second weakening holes 1124 can be 18.

[0044] For example, the supporting middle part 112 of the inner panel body 11 can be provided with 5 supporting vertical beams 1121 and 6 first hollow areas 1122.

[0045] It should be noted that the aforementioned supporting vertical beam 1121 can be a strip structure arranged substantially parallel to the length direction, or it can be a structure extending substantially parallel to the length direction. That is, the supporting vertical beam 1121 can be a regular elongated shape or an irregular structural shape. When the supporting vertical beam 1121 is a regular elongated structure, due to manufacturing errors or structural limitations of the inner plate body 11, the supporting vertical beam 1121 can be deflected relative to the length direction. When the supporting vertical beam 1121 is an irregular shape, the extension direction of the longer structure of the supporting vertical beam 1121 can be substantially parallel to the length direction. For example... Figures 1-3 As shown, the supporting vertical beam 1121 can be a strip structure with a rectangular middle section and gradually increasing width at both ends, with the extension direction of the strip structure in the longer direction parallel to the aforementioned length direction.

[0046] In some embodiments, the first hollow area 1122 includes a rectangular structure to simplify the arrangement of the first hollow area 1122. The corners of the rectangular structure may be rounded to provide both structural support and collapse protection.

[0047] In some embodiments, such as Figure 4 As shown, in the thickness direction of the inner panel 1 of the engine hood, the support front end 111 protrudes beyond the mounting section 113. The support front end 111 provides support for the outer panel 21, and since the front end is a high-pressure area, this structural design of the support front end 111 improves its dent resistance. By employing a support front end 111 that protrudes beyond the mounting section 113 in thickness, it provides support, improves dent resistance, and weakens the structure, achieving a balance between the engine hood's robust dent resistance and pedestrian protection requirements.

[0048] Furthermore, at the end of the supporting front end 111 that is away from the installation section 113, the inner panel body 11 also includes a front edge 114. The supporting front end 111 can also protrude relative to the front edge 114 in terms of thickness, so as to use the supporting front end 111 to form a supporting effect on the outer panel 21.

[0049] In the above embodiment, the supporting front end 111 may be provided with a plurality of third weakening holes 1111, which are distributed along the width direction. The third weakening holes 1111 increase the possibility of collapse, improve the pedestrian protection score in this area, and can also reduce the size design of the engine hood outer panel support plate 12, which helps to achieve cost reduction development.

[0050] The third weakening hole 1111 may include a first end near the mounting section 113, and a glue groove 1112 is provided between the first ends of two adjacent third weakening holes 1111. After glue is injected into the glue groove 1112, the inner panel body 11 and the engine hood outer panel 21 can be connected by shock-absorbing glue. The glue groove 1112 at one end of the third weakening hole 1111 can also form a crumple protection effect in the area on one side of the third weakening hole 1111.

[0051] The aforementioned third weakening hole 1111 can be an elongated strip-shaped structure extending along the length direction, and the glue groove 1112 can be an elongated strip-shaped structure extending along the width direction. The aforementioned third weakening hole 1111 and glue groove 1112 can be rectangular or arc-shaped structures. The aforementioned third weakening hole 1111 extending along the length direction can mean that the extension direction of the third weakening hole 1111 is substantially parallel to the length direction, and the extension direction of the glue groove 1112 is substantially parallel to the width direction.

[0052] In some embodiments, such as Figure 5As shown, the outer panel support plate 12 includes a main structure 121 and multiple mounting claws 122 disposed along the edge of the main structure 121. The mounting claws 122 are welded and fixed to the inner panel body 11. The main structure 121 has a second hollow area 123 distributed along the width direction. The outer panel support plate 12 is disposed between the support front end 111 and the support middle part 112. The outer panel support plate 12 is optimized based on the support front end 111 and support middle part 112 of the engine hood inner panel 1, which helps to reduce the size of the outer panel support plate 12 structure, meet the requirements of dent resistance and pedestrian protection, and also achieve cost reduction development, greatly improving the performance of the engine hood assembly 2.

[0053] Furthermore, such as Figure 1 As shown, the left and / or right sides of the support front end 111 may have engine hood latch assembly mounting surfaces for mounting the left engine hood latch mounting plate assembly and / or the right engine hood latch mounting plate assembly. The rear end and / or right side of the support middle section 112 may have engine hood left hinge and / or right hinge mounting surfaces for mounting the left engine hood hinge reinforcement plate assembly and / or the right engine hood hinge reinforcement plate assembly. The engine hood inner panel 1 has strong structural versatility, and the latch structure and hinge structure of the later engine hood assembly 2 can be developed according to this idea, which can reduce modification time, shorten the project development cycle, and reduce development costs.

[0054] This application further provides an engine hood assembly 2, such as Figures 6-8 As shown, the engine hood assembly 2 includes an outer panel 21 and the aforementioned engine hood inner panel 1.

[0055] The inner panel 1 and outer panel 21 of the aforementioned engine hood can be connected into a whole after edge pressing. The outer panel 21 is supported by the support vertical beam 1121 structure supporting the middle part 112 and the outer panel support plate 12 structure, which plays a role in weakening the middle part and at the same time compensates for the overall bending resistance of the middle part, thus achieving a balance between the dent resistance performance of the engine hood assembly 2 and the pedestrian protection requirements.

[0056] In addition, such as Figure 8 As shown, the aforementioned supporting vertical beam 1121 may be provided with a cavity 1121a to provide both structural support and collapse protection. The depth of the vertical beam cavity 1121a is 15mm-25mm; for example, the depth of the vertical beam cavity 1121a may be 19mm.

[0057] This application further provides a vehicle that includes the aforementioned hood inner panel 1 or the aforementioned hood assembly 2.

[0058] The inner panel body 11 of the aforementioned engine hood inner panel 1 forms a support structure for the outer panel 21 at the support front end, the support middle part, and the outer panel support plate 12 located between the support front end and the support middle part. The support middle part 112 forms a beamless support effect through the support vertical beam 1121 and the first hollow area 1122. While ensuring the overall strength of the inner panel body 11, it helps to achieve the lightweighting of the engine hood inner panel 1 and the crumple protection for pedestrians in collision scenarios.

[0059] The aforementioned vehicles may be buses, ambulances, trucks, vans, commercial vehicles, private cars, etc., and this application does not impose any restrictions on this.

[0060] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
