[0051] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0052] like Figure 1 and Figure 2 As shown, the hood inner panel 1 of the embodiment of the present invention includes an inner panel body 11, and the inner panel body 11 has a first surface 111 and a second surface 112. The first surface 111 is a finishing surface facing the engine compartment, and the second surface 112 faces the hood outer panel 2. After the hood 100 is opened, the first surface 111 is a visible surface. The first surface 111 directly serves as the visible appearance of the local area after the hood 100 is opened, and no concealing parts are provided. The second surface 112 corresponds to the hood outer panel 2, and the second surface 112 is an invisible surface.

[0053] A connecting component 12 is provided on the second surface 112 of the inner panel body 11. There are multiple connecting components 12, and the multiple connecting components 12 are distributed at intervals on the second surface 112. The inner panel body 11 is connected to the engine hood outer panel 2 through the connecting component 12, so that the mounting structure between the engine hood inner panel 1 and the engine hood outer panel 2 is hidden, making the visual appearance of the engine hood inner panel 1 more neat.

[0054] The connecting component 12 on the hood inner panel 1 of the embodiment of the present invention is arranged on the side facing the hood outer panel 2, reducing the parts exposed to the outside and making the side of the hood inner panel 1 facing the engine compartment neater. The first surface 111 of the hood inner panel 1 is used as a finishing surface, and there is no need to install additional parts to cover up the ugliness, which can make the appearance neater and smoother.

[0055] For example, in electric vehicles, the requirements for heat resistance of engine hood parts are gradually reduced, and thermal insulation pads are no longer required. The engine hood inner panel 1 of the embodiment of the present invention does not need thermal insulation pads or other components to cover up the ugliness, and can be directly used as a visible surface, thereby improving the neatness of the appearance.

[0056] Optionally, the first surface 111 is a flat plane, or a smooth curved surface, or a smooth visible surface that is a combination of a flat surface and a curved surface. A convex-concave structure with an appearance shape may also be provided in a local area of ​​the first surface 111 .

[0057] In some embodiments, the inner panel body 11 is made of plastic or a composite material.

[0058] According to the structural design requirements of the hood inner panel 1, while meeting the basic performance of the hood inner panel 1, the material of the inner panel body 11 can be selected. For example, based on the plasticity, structural strength, heat resistance, lightness and other requirements of the material, suitable materials can be selected for processing the hood inner panel 1.

[0059] For example, when used in electric vehicles, since the heat resistance requirements for the hood inner panel 1 are reduced, the inner panel body 11 is made of plastic material, which not only meets the basic performance requirements but also can achieve lightweight. When processing the hood inner panel 1, it is also convenient to obtain a better appearance.

[0060] like Figure 2 As shown, in some embodiments, a plurality of ribs are provided on the inner panel body 11, and the plurality of ribs are provided on the second surface 112. The ribs are used to structurally reinforce the inner panel body 11. For example, after reducing the thickness and weight of the inner panel body 11, the structural strength and stability of the inner panel body 11 can be effectively improved by providing the ribs, thereby ensuring that the inner panel body 11 can meet the requirements of its structural performance.

[0061] The rib plate of the embodiment of the present invention is disposed on the second surface 112 of the inner plate body 11 , so as not to affect the first surface 111 (also the visible surface) of the inner plate body 11 , thereby ensuring that the first surface 111 is smooth, flat and neat.

[0062] like Figure 2As shown, in some embodiments, the density of the ribs around the connecting component 12 is greater than the density of the ribs in other areas on the second surface 112, and the height of the ribs around the connecting component 12 is less than the height of the ribs in other areas on the second surface 112.

[0063] The embodiment of the present invention can ensure the structural strength and stability of the corresponding area by increasing the density of the ribs around the connecting component 12 and reducing the height of the ribs. At the same time, it can avoid shrinkage on the surface of the inner panel body 11 due to problems such as material shrinkage rate and temperature uniformity when the inner panel body 11 is injection molded with plastic or other materials, resulting in visible shrinkage marks on the first surface 111 of the inner panel body 11.

[0064] Optionally, the density in the embodiment of the present invention can be adjusted by adjusting the number of ribs around the connecting component 12 and the spacing between adjacent ribs.

[0065] like Figure 2 As shown, in some embodiments, the ribs include a first rib 131 and a second rib 132, a plurality of first ribs 131 are arranged at intervals along a first direction, a plurality of second ribs 132 are arranged at intervals along a second direction, and the first direction and the second direction intersect.

[0066] Specifically, the first ribs 131 are arranged at intervals along the first direction, and the second ribs 132 are arranged at intervals along the second direction, so that the first ribs 131 and the second ribs 132 can be arranged in a grid-like staggered manner, thereby effectively improving the structural reinforcement of the inner plate body 11 and reducing the weak areas on the inner plate body 11.

[0067] Optionally, multiple first ribs 131 are arranged in parallel and at intervals along the first direction, and multiple second ribs 132 are arranged in parallel and at intervals along the second direction. The multiple first ribs 131 can be arranged at equal intervals or at variable intervals, and the multiple second ribs 132 can be arranged at equal intervals or at variable intervals.

[0068] Alternatively, since the inner plate body 11 is not a flat plate with a regular shape, in order to improve the structural strength of the corresponding area of ​​the inner plate body 11 in some areas, multiple first ribs 131 are arranged at intervals along the first direction, and multiple second ribs 132 are arranged at intervals along the second direction, but adjacent first ribs 131 and adjacent second ribs 132 are not parallel.

[0069] Optionally, the first direction and the second direction are arranged at an angle of 60°-90° to avoid the problem of poor uniformity of structural strength on the inner panel body 11 due to the angle being too small.

[0070] For example, the first direction and the second direction are arranged vertically, the first direction is the length direction of the inner plate body 11, that is, the X direction in the figure, and the second direction is the width direction of the inner plate body 11, that is, the Y direction in the figure.

[0071] like Figure 2 As shown, in some embodiments, the spacing between two adjacent first ribs 131 is 50mm-100mm; the spacing between two adjacent second ribs 132 is 50mm-100mm; the height of the first rib 131 and the second rib 132 is 0.5mm-5mm.

[0072] Specifically, the spacing between two adjacent first ribs 131 and the spacing between two adjacent second ribs 132 can be 50mm, 60mm, 66mm, 71mm, 95mm or 100mm, and the height of the first rib 131 and the second rib 132 can be 0.5mm, 1mm, 1.25mm, 2.3mm, 4mm, 4.9mm or 5mm.

[0073] When the spacing between adjacent first ribs 131 and the spacing between adjacent second ribs 132 are less than 50 mm, the ribs may be too dense, increasing the cost and difficulty of processing; when the spacing between adjacent first ribs 131 and the spacing between adjacent second ribs 132 are greater than 100 mm, the uniformity of the structural strength on the inner panel body 11 may be poor, making it difficult to ensure the structural stability of the inner panel body 11; when the height of the first rib 131 and the second rib 132 is less than 0.5 mm, a good supporting and reinforcing effect cannot be achieved, and it is often necessary to increase the thickness of the inner panel body 11 to improve the structural strength; when the height of the first rib 131 and the second rib 132 is greater than 5 mm, the total thickness of the hood inner panel 1 may be increased, and when plastic or other materials are used for injection molding, the injection molding quality at the reinforcing ribs may not meet the standards.

[0074] The embodiment of the present invention can meet the structural strength requirements of the engine hood inner panel 1 and the installation space requirements by rationally designing the spacing between the ribs and the height of the ribs, while facilitating the guarantee of processing quality.

[0075] like Figure 2As shown, in some embodiments, the second surface 112 has a first area, the first area is located in the circumference of the connecting component 12, the first ribs 131 and the second ribs 132 are arranged on the second surface 112 outside the first area, and the ribs also include a plurality of third ribs 133, and the plurality of third ribs 133 are arranged in the first area. In the embodiment of the present invention, the third ribs 133 are arranged in the first area in the circumference of the connecting component 12 to ensure the structural stability of the first area and improve the problem of shrinkage in the corresponding area caused by the connecting component 12 during the injection molding process. Different types of rib structures are used in the first area in the circumference of the connecting component 12 and other areas on the second surface 112, thereby ensuring the structural strength of the inner plate body 11 and ensuring the smooth appearance of the first surface 111 of the inner plate body 11 after molding.

[0076] Optionally, the density of the third ribs 133 in the first area is greater than the density of the first ribs 131 and the second ribs 132 in other areas on the second surface 112, and the height of the third ribs 133 is less than the height of the first ribs 131 and the second ribs 132, thereby ensuring the structural stability of the first area while preventing shrinkage in the first area.

[0077] Furthermore, the height of the third rib 133 is 0.1 mm-0.5 mm. Compared with the first rib 131 and the second rib 132, the height of the third rib 133 is lower, which can prevent shrinkage in the circumferential area of ​​the connecting component 12 during the molding process.

[0078] The multiple third ribs 133 are divided into a first rib group and a second rib group. The first rib group includes multiple third ribs 133 spaced apart along the third direction. The second rib group includes multiple third ribs 133 spaced apart along the fourth direction. The third direction intersects with the fourth direction. The spacing between two adjacent third ribs 133 in the same rib group is 10mm-30mm.

[0079] The third ribs 133 may be arranged in the same manner as the first ribs 131 and the second ribs 132 , and may be arranged in a grid pattern within the first region. For example, the third direction may be the same as the first direction, and the fourth direction may be the same as the second direction.

[0080] When the height of the third rib 133 is less than 0.1 mm, it cannot play a good reinforcement effect and it is difficult to form an effective rib network structure with the first rib 131 and the second rib 132. When the height of the third rib 133 is greater than 0.5 mm, shrinkage is likely to occur. When the spacing between two adjacent third ribs 133 in the same rib group is less than 10 mm, it is easy to cause the rib density to be too high. When the spacing between two adjacent third ribs 133 in the same rib group is greater than 30 mm, it will be impossible to make up for the problem of reduced structural strength of the first area of ​​the inner plate body 11 due to the reduced height of the third rib 133.

[0081] like Figure 2 As shown, in some embodiments, at least part of the connecting components 12 are arranged in the middle area of ​​the second surface 112, and other connecting components 12 are arranged in the circumferential area of ​​the second surface 112. Specifically, a plurality of connecting components 12 are arranged in the middle area of ​​the second surface 112, and a plurality of connecting components 12 are arranged at intervals in the circumferential area of ​​the second surface 112, so as to ensure that the hood inner panel 1 can be stably connected to the hood outer panel 2, and avoid the phenomenon of shaking or hollowing in the middle area or edge area of ​​the inner panel body 11 due to unstable connection.

[0082] like Figure 2 As shown, three connecting components 12 labeled 12 (a), 12 (b), and 12 (c) are located in the middle area of ​​the second surface 112, and the other connecting components 12 are located in the circumferential area of ​​the second surface 112.

[0083] like Figure 3-Figure 5 As shown, in some embodiments, the connecting component 12 includes a base 121 and a connector 122, the base 121 is connected to the inner panel body 11, and the connector 122 is movably connected to the base 121 to adjust the connector 122 to align with the hole position on the engine hood outer panel 2.

[0084] Specifically, a sliding groove is provided on the base 121, and the connector 122 has a clamping column connected to the sliding groove and a plug connector fixedly plugged into the hole of the engine hood outer panel 2. The clamping column can move in the sliding groove, so as to adjust the position of the connector 122 relative to the base 121 in the length direction of the sliding groove. The connector 122 is also provided with two limit plates, which are in abutment with the base 121. The two limit plates are used to limit the movement of the connector 122 relative to the base 121 in the length direction of the connector 122. During installation, the position of the connector 122 on the base 121 can be adjusted to avoid mismatching of the holes due to deviation of the holes on the engine hood outer panel 2, thereby ensuring that it is installed in place.

[0085] like Figure 3-Figure 5As shown, in some embodiments, at least part of the connecting components 12 further include positioning members 123 , and the positioning members 123 are used to guide the corresponding connecting components 12 to align with the holes on the engine hood outer panel 2 .

[0086] In order to facilitate alignment, the positioning member 123 is used for positioning, and the plug-in member 122 is guided to correspond to the hole position on the engine hood outer panel 2, thereby improving the installation efficiency. The positioning member 123 is a positioning column, and the end of the positioning column is tapered. Accordingly, a hole corresponding to the positioning column is provided on the engine hood outer panel 2.

[0087] like Figure 2-Figure 5 As shown, in some embodiments, the connection components 12 located in the middle area of ​​the second surface 112 are all provided with positioning members 123. That is, the three connection components 12 labeled 12(a), 12(b), and 12(c) are provided with positioning members 123.

[0088] According to the installation sequence of the hood inner panel 1, it is necessary to install the connecting component 12 located in the middle area of ​​the second surface 112 first, and then install the connecting component 12 located in the circumferential area of ​​the inner panel body 11. Therefore, the positioning member 123 is arranged on the connecting component 12 located in the middle area of ​​the second surface 112. After the hood inner panel 1 is connected to the hood outer panel 2 through the connecting component 12 in the middle area of ​​the second surface 112, the connecting component 12 in the circumferential area of ​​the second surface 112 is installed, and the plug connector can be fine-tuned.

[0089] Furthermore, the positioning member 123 is arranged on the base 121 of the connecting component 12 located in the middle area of ​​the second surface 112. The positioning member 123 and the connector 122 are arranged side by side with a relatively close distance, which can reduce the error. The positioning member 123 can better guide the connector 122 to align with the hole position on the engine hood outer panel 2.

[0090] In a specific embodiment, a first rib 131, a second rib 132, a third rib 133, a base 121 and a positioning member 123 are provided on the inner plate body 11, and the inner plate body 11, the first rib 131, the second rib 132, the third rib 133, the base 121 and the positioning member 123 are integrally formed by plastic, and the connector 122 is detachably connected to the base 121.

[0091] like Figure 6 As shown, the engine hood 100 of the embodiment of the present invention includes an engine hood outer panel 2 and an engine hood inner panel 1. The engine hood outer panel 2 has a connecting hole. The engine hood inner panel 1 is the engine hood inner panel 1 in the above embodiment. The engine hood inner panel 1 is connected to the engine hood outer panel 2 through a connecting component 12.

[0092] At least part of the beneficial effects achieved by the engine hood 100 in the embodiment of the present invention are the same as the beneficial effects achieved by the engine hood inner panel 1 in the above-mentioned embodiment, so they will not be repeated.

[0093] like Figure 7 and Figure 8 As shown, in some embodiments, the engine hood 100 further includes a sound-absorbing cotton layer 3, which is disposed between the engine hood inner panel 1 and the engine hood outer panel 2. The sound-absorbing cotton layer 3 can absorb sound, replacing the original engine hood heat insulation pad. The weight of the sound-absorbing cotton layer 3 is more than 50% lighter than that of the heat insulation pad, and the acoustic performance can still meet the requirements, making it more suitable for application in electric vehicles.

[0094] In some embodiments, the thickness of the sound-absorbing cotton layer 3 is 10-20 mm. The sound-absorbing cotton layer 3 can be selected with different thicknesses according to specific requirements. At the same time, the compressibility of the sound-absorbing cotton layer 3 is very high, which can reach more than 70%. The space requirement is not high, which can avoid the problem of insufficient space between the engine hood inner panel 1 and the engine hood outer panel 2, and can also avoid the problem of insufficient gap between the engine hood and engine compartment parts.

[0095] Furthermore, the sound-absorbing cotton layer 3 is connected to the second surface 112 of the engine hood inner panel 1 , for example, by welding to the engine hood inner panel 1 .

[0096] Optionally, a through hole 31 is provided on the sound-absorbing cotton layer 3, and the through hole 31 corresponds to the connecting component 12 in the corresponding area of ​​the engine hood inner panel 1, so that the connecting component 12 can be connected to the connecting hole on the engine hood outer panel 2 through the through hole 31, thereby avoiding the sound-absorbing cotton layer 3 affecting the installation and use of part of the connecting component 12.

[0097] The vehicle according to the embodiment of the present invention comprises the engine hood inner panel 1 in the above embodiment and / or the engine hood 100 in any one of the above embodiments.
