It not only plays an important role in the appearance of the vehicle, but also covers the engine in the engine compartment, and the engine generates a lot of heat when it is working. Therefore, the main requirements for the engine hood are heat insulation and sound insulation, light weight, and strong rigidity. Among them, the engine hood inner panel plays an important role in the heat dissipation effect in the engine compartment.

[0003] However, in order to make the existing engine hood have a higher structural strength, reinforcing ribs are usually provided on the inner plate of the engine hood. The provision of the reinforcing ribs together with components such as the muffler heat shield forms a narrow space, which is not conducive to the discharge of hot air. Utility Model Content

[0004] In view of this, the utility model aims to provide an engine hood inner panel to facilitate the discharge of hot air in the cabin and improve the heat dissipation effect of the cabin.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] An engine hood inner panel comprises an inner panel body, on which reinforcing ribs and guide ribs are provided;

[0007] The reinforcing ribs are arranged along the edge of the inner plate body, and the reinforcing ribs include a first rib body arranged at one end of the inner plate body in the front-rear direction of the vehicle, and a second rib body arranged at the left and right sides of the inner plate body;

[0008] In the front-rear direction of the whole vehicle, the guide rib is arranged at the other end of the inner plate body and extends along the front-rear direction of the whole vehicle.

[0009] Furthermore, the cross section of the first rib and / or the second rib includes two symmetrically arranged parts, and in the up-down direction of the vehicle, the distance between the two parts gradually decreases from top to bottom.

[0010] Furthermore, the inner plate body includes an annular edge portion, and a reinforcement portion disposed in the edge portion;

[0011] Along the front-rear direction of the vehicle, the reinforcement part is connected between the front and rear ends of the edge part, and is surrounded with the edge part to form a heat dissipation hole;

[0012] The first reinforcement body is arranged at the front end of the edge part, the second reinforcement body is arranged at the left and right ends of the edge part, and the guide rib is arranged at the rear end of the edge part.

[0013] Furthermore, a reinforcing beam is connected between the left side and / or right side of the reinforcing portion and the edge portion;

[0014] A mounting portion is provided at a connection position between the reinforcing beam and the edge portion, and the mounting portion is used to mount the engine hood inner panel on a vehicle body.

[0015] Furthermore, the reinforcement beams are multiple and spaced apart along the front-rear direction of the vehicle, and at least one of the reinforcement beams is provided with a reinforcement protrusion;

[0016] The reinforcement protrusion extends along the length direction of the reinforcement beam.

[0017] Furthermore, the first ribs and the second ribs are connected with each other in a smooth transition; and / or,

[0018] The guide ribs are multiple and are arranged at intervals along the left-right direction of the inner plate body.

[0020] At least part of the guide ribs extends between the extension sections on both sides.

[0021] Furthermore, along the direction from the front to the rear of the vehicle, the width of the inner panel body gradually decreases.

[0022] Compared with the prior art, the utility model has the following advantages:

[0023] The engine hood inner panel described in the utility model can not only improve the structural strength of the inner panel body by arranging reinforcing ribs and guide ribs, but also can make the reinforcing ribs form a semi-ring structure, which can prevent the hot air generated by the engine from diffusing to other parts of the cabin, and the guide ribs can guide the hot air to be discharged from the cabin, thereby facilitating the discharge of hot air in the cabin and improving the heat dissipation effect of the cabin.

[0024] In addition, in the vertical direction of the vehicle, the distance between the two parts of the cross section of the first rib and / or the second rib is gradually reduced from top to bottom, which can reduce the width of the edge of the inner panel body, thereby allowing a larger heat dissipation hole to be opened on the inner panel body, which can further improve the heat dissipation effect of the engine hood inner panel. The inner panel body includes an annular edge portion and a reinforcement portion, which can enable a larger heat dissipation hole to be opened while meeting the strength requirements, which is conducive to ensuring the heat dissipation effect and improving the protection effect for pedestrians.

In addition, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0040] In addition, in the description of the present invention, unless otherwise clearly defined, the terms "installation", "connection", "connection", and "connector" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0042] This embodiment relates to an engine hood inner panel, including an inner panel body 1, on which a reinforcing rib and a guide rib 103 are provided. The reinforcing rib is provided along the edge of the inner panel body 1, and the reinforcing rib includes a first rib body 101 provided at one end of the inner panel body 1 in the front-rear direction of the whole vehicle, and a second rib body 102 provided at the left and right sides of the inner panel body 1. In the front-rear direction of the whole vehicle, the guide rib 103 is provided at the other end of the inner panel body 1 and extends along the front-rear direction of the whole vehicle.

[0043] The engine hood inner panel of the present embodiment can not only improve the structural strength of the inner panel body 1 by providing reinforcing ribs and guide ribs 103, but can also form the reinforcing ribs into a semi-ring structure, thereby preventing the hot air generated by the engine from diffusing to other parts of the cabin, and the guide ribs 103 can guide the hot air out of the cabin, thereby facilitating the discharge of hot air in the cabin and improving the heat dissipation effect of the cabin.

[0044] Based on the above overall introduction, an exemplary structure of the engine hood inner panel of this embodiment is referred to as follows: Figure 1 to Figure 1 As shown in , as a preferred embodiment, in this embodiment, the width of the inner panel body 1 gradually decreases along the direction from the front to the rear of the vehicle. At the same time, the inner panel body 1 is also roughly triangular, and the advantage of the triangle having good stability can be used to make the inner panel body 1 have good structural strength. In addition, the engine hood inner panel can be applied to low-lying sports cars in specific use. Of course, it can also be set to the shape used in existing ordinary cars and applied to ordinary cars.

[0045] Combination Figure 1 and Figure 2 As shown in the figure, as a preferred embodiment, the inner plate body 1 of this embodiment includes an annular edge portion 1a and a reinforcement portion 1b arranged in the edge portion 1a. In addition, along the front-rear direction of the vehicle, the reinforcement portion 1b is connected between the front and rear ends of the edge portion 1a, and is surrounded by the edge portion 1a to form a heat dissipation hole K. The inner plate body 1 of this embodiment adopts this structure, which not only allows it to open a larger heat dissipation hole K under the premise of meeting the strength requirements, which is conducive to ensuring the heat dissipation effect, but also can improve the protection effect on pedestrians.

[0046] Among them, Figure 2 As shown in , the reinforcing ribs and guide ribs 103 are both arranged on the edge portion 1a, that is, the first rib body 101 is arranged at the front end of the edge portion 1a, and the second rib body 102 is arranged at the left and right ends of the edge portion 1a. In addition, due to the arrangement of the reinforcing ribs of the above structure, a semi-closed annular structure with an opening facing backward is formed. At the same time, the rear end of the inner plate body 1 is likely to form a relatively closed space with the muffler heat shield and other components below it, which is not conducive to the circulation of airflow in the cabin. Therefore, Figure 1 As shown in FIG. 1 , in this embodiment, the guide rib 103 is disposed at the rear end of the edge portion 1 a to facilitate guiding the hot air flow in the cabin to be discharged.

[0047] In addition, in order to facilitate the arrangement of the guide ribs 103 and improve the guide effect, Figure 2 As shown in the figure, the rear end of the edge portion 1a is longer in the length direction of the vehicle, while the front end and the side of the edge portion 1a are both long strips. This arrangement can increase the area of ​​the heat dissipation hole K, and at the same time, a longer guide rib 103 can be arranged at the other end of the edge portion 1a, which can improve the guide effect of hot air.

[0048] As a further embodiment, Figure 3As shown in , the cross-sections of the first rib 101 and the second rib 102 each include two symmetrically arranged parts, and in the up-down direction of the vehicle, the spacing between the two parts gradually decreases from top to bottom, that is, the cross-sections of both are in a "V" shape. This can reduce the width of the edge portion 1a, thereby allowing a larger heat dissipation hole K to be opened on the inner panel body 1, which can further improve the heat dissipation effect of the inner panel of the engine hood. It should be noted here that in addition to setting the cross-sections of the first rib 101 and the second rib 102 to be in a "V" shape, it is also possible to set the cross-section of one of the first rib 101 and the second rib 102 to be in a "V" shape, and set the cross-section of the other rib to be in a conventional "U" shape or other shapes.

[0049] In addition, continue to refer to Figure 1 and Figure 2 As shown in , as a preferred implementation form, in this embodiment, the first rib 101 and the second rib 102 are connected with each other in a smooth transition, that is, the left and right ends of the first rib 101 are respectively connected with the second rib 102 on the corresponding side. Such a configuration can not only improve the reinforcing effect of the reinforcing rib on the structural strength of the inner plate body 1, but also prevent the gap between the two, so that the hot air is dissipated to other parts and affect the working performance of the components in other parts.

[0050] In addition, in order to further improve the heat dissipation effect of the hot air in the cabin, a plurality of guide ribs 103 are arranged at intervals along the left and right directions of the inner panel body 1. Thus, a plurality of guide channels can be formed at the other end (i.e., the rear end) of the inner panel body 1, which can prevent the hot air from being turbulent and reducing the flow efficiency, thereby facilitating the discharge of the hot air. Figure 1 As shown in FIG. 1 , as a specific embodiment, the number of the guide ribs 103 is four and is arranged at intervals along the left-right direction of the inner plate body 1. Of course, during the specific implementation, the number of the guide ribs 103 can be adjusted.

[0051] It should be noted that connecting the first rib 101 and the second rib 102 in a smooth transition and providing a plurality of guide ribs 103 is only a preferred implementation. Of course, in specific implementation, the first rib 101 and the second rib 102 may not be connected in a smooth transition, or only one guide rib 103 may be provided according to design requirements.

[0052] As a further embodiment, one end (i.e., the rear end) of each side second rib 102 has an extension section 1021 extending along the front-rear direction of the vehicle, and at least part of the guide rib 103 extends between the two side extension sections 1021. This design can form an outlet for hot air to flow out between the two side extension sections 1021, and the guide rib 103 can better guide the hot air out of the cabin. Figure 1 and Figure 2As shown in , as a preferred embodiment, only two of the guide ribs 103 extend between the extension sections 1021 on both sides. It should be noted that in addition to extending part of the guide ribs 103 between the extension sections 1021 on both sides, all of the guide ribs 103 may also be extended between the extension sections 1021 on both sides.

[0053] In addition, in order to improve the use effect, such as Figure 1 and Figure 2 As shown in FIG. 1 , a reinforcing beam 104 is connected between the left and right sides of the reinforcing portion 1b and the edge portion 1a, and a mounting portion is provided at the connection position between the reinforcing beam 104 and the edge portion 1a, and the mounting portion is used to mount the engine hood inner panel on the vehicle body. Moreover, the reinforcing beam 104 divides the heat dissipation hole K on the corresponding side into a plurality of sub-holes, so that the inner panel body 1 can have a good heat dissipation effect while having sufficient torsional rigidity.

[0054] Furthermore, as a further embodiment, in order to improve the structural strength of the hood inner panel, the reinforcing beams 104 are arranged in a plurality at intervals along the front-to-back direction of the vehicle, and at least one of the reinforcing beams 104 is provided with a reinforcing protrusion 1041, which extends along the length direction of the reinforcing beam 104. By providing the reinforcing protrusion 1041 on the reinforcing beam 104, the structural strength of the reinforcing beam 104 and the structural strength of the inner panel body 1 as a whole can be improved. Among them, as a specific embodiment, the reinforcing beams 104 are arranged in two groups symmetrically, and each group of reinforcing beams 104 is arranged in two groups at intervals along the front-to-back direction of the vehicle, and the two reinforcing beams 104 are respectively arranged at the front and rear ends of the inner panel body 1, and the mounting portion is arranged in a one-to-one correspondence with the reinforcing beams 104.

[0055] The mounting portion of this embodiment is specifically a mounting hole 1042. In addition, as a preferred embodiment, Figure 1 As shown in the figure, the reinforcing beam 104 at the front end of the inner panel body 1 extends in the left-right direction of the vehicle, and due to its large length, the reinforcing protrusion 1041 does not extend to the mounting hole 1042. At this time, in order to improve the mounting strength of the hood inner panel, a boss 105 is provided at the connection position between the reinforcing beam 104 and the edge portion 1a, and the protruding direction of the boss 105 is consistent with the protruding direction of the reinforcing protrusion 1041, and the mounting hole 1042 is specifically provided on the boss 105. The reinforcing beam 104 at the rear end of the inner panel body 1 is tilted backward, and the reinforcing protrusion 1041 on the reinforcing beam 104 extends to the edge portion 1a, so the mounting hole 1042 on the reinforcing beam 104 is provided on the reinforcing protrusion 1041.

[0056] In addition, in order to improve the heat dissipation effect of the inner plate body 1, the heat dissipation hole K is usually designed to be as large as possible, and also to better protect pedestrians. Figure 1 and Figure 2 As shown in the figure, a protruding portion 106 extending along the front-rear direction of the vehicle is also provided on the reinforcement portion 1b. It should be mentioned that the shape of the protruding portion 106 is not limited to the shape shown in the figure, and it can be adjusted accordingly according to design requirements.

[0057] The inner panel of the engine hood of this embodiment adopts the above structure to guide and facilitate the discharge of hot air in the cabin. Especially for low-lying vehicles with smaller Z-direction space, it can better dissipate the heat in the cabin and prevent the heat in the cabin from dissipating to other parts, which can effectively ensure the normal use of components such as air filters, various wiring harness connectors and taillights.

[0058] In addition, another purpose of this embodiment is to provide an engine hood, comprising the above engine hood inner panel, and an engine hood outer panel arranged outside the engine hood inner panel. In order to further improve the use effect, during the specific implementation, a plurality of vents arranged roughly evenly can also be provided on the engine hood outer panel for heat dissipation.

[0059] In addition, this embodiment also provides a vehicle, which is provided with an engine hood as described above.

[0060] The vehicle and the engine hood of this embodiment have all the beneficial effects of the above-mentioned engine hood inner panel, which will not be described in detail here.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
