Description

Technical Field

[0001] This application relates to the technical field of engine hoods, and more particularly to a support plate for an outer panel of an engine hood, an engine hood assembly, and a vehicle. Background Technology

[0002] The engine hood outer panel is one of the important body parts at the front of the vehicle. A support plate is installed on the inner side of the engine hood outer panel to increase its rigidity.

[0003] To achieve the goal of vehicle lightweighting, weight reduction holes are usually provided on the support plate. Although providing weight reduction holes will reduce the weight of the support plate, it will also prevent the weight reduction holes from enhancing the rigidity of the outer hood panel, resulting in a reduction in the overall enhancement effect of the support plate on the rigidity of the outer hood panel.

[0004] The existing support plate structure is poorly designed and cannot effectively disperse and withstand external impact forces, thus failing to meet the stiffness enhancement requirements of the engine hood outer panel. Utility Model Content

[0005] This application addresses, to at least some extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide a support plate for an engine hood outer panel, an engine hood assembly, and a vehicle. By setting multiple weight-reduction holes and providing support legs at the weight-reduction holes, the support legs compensate for the loss of stiffness reinforcement of the engine hood outer panel caused by the weight-reduction holes in the support plate body. Furthermore, the support legs are arranged in different directions so that the support legs can provide support to the engine hood outer panel in different directions, thereby increasing the stiffness reinforcement effect of the support plate on the engine hood outer panel.

[0007] To achieve the above objectives, in a first aspect, this application provides a support plate for an engine hood outer panel, comprising: The main body is connected to one side of the outer panel of the engine hood; the main body is provided with multiple weight reduction holes; the multiple weight reduction holes are set independently of each other; Support legs are provided in multiple configurations, with each support leg corresponding to a weight-reducing hole. One end of the support leg along its length is connected to one side edge of the corresponding weight-reducing hole, while the other end of the support leg along its length extends away from the main body and is inclined toward the opposite side edge of the corresponding weight-reducing hole. At least some of the support legs are connected to the edges on different sides of the corresponding weight reduction holes.

[0008] In the technical solution, weight-reducing holes are set on the main body to reduce its weight. While reducing the same weight, setting multiple small holes can better distribute the stress acting on the main body and also give it better structural rigidity, thus ensuring the body's reinforcement effect on the engine hood outer panel. One end of the support leg is connected to one side edge of the corresponding weight-reducing hole, and the other end extends away from the main body and is inclined towards the opposite side edge of the corresponding weight-reducing hole. This allows the support leg to be positioned at the weight-reducing hole, compensating for the loss of reinforcement rigidity on the engine hood outer panel due to the weight-reducing holes. Furthermore, by connecting some support legs to the edges of different sides of the corresponding weight-reducing holes, the support legs are arranged in different directions in space, allowing them to support the engine hood outer panel in different directions, thereby increasing the reinforcement effect of the support plate on the engine hood outer panel.

[0009] In some embodiments of this application, a plurality of weight-reducing holes are arranged along the length of the body, and the support legs corresponding to adjacent weight-reducing holes are connected to the edges of different sides of the weight-reducing holes. And / or, multiple support legs are arranged along the length of the body, and adjacent support legs are connected to the edges on different sides of the corresponding weight reduction holes.

[0010] In the technical solution, by connecting the support legs corresponding to adjacent weight reduction holes to different edges of the weight reduction holes, the support legs corresponding to two adjacent weight reduction holes are arranged in different directions in space. This allows the support legs to support the surrounding area of ​​the weight reduction holes in different directions, thereby increasing the rigidity of the main body and enhancing the rigidity of the engine hood outer panel in the surrounding area of ​​the weight reduction holes. By connecting adjacent support legs to the edges of the corresponding weight reduction holes on different sides, the adjacent support legs are arranged in different directions in space, allowing the support legs to support the main body in different directions, thereby increasing the rigidity of the main body and enhancing the rigidity of the engine hood outer panel.

[0011] In some embodiments of this application, the projection of the support leg on the body falls into the corresponding weight-reducing hole; the projection patterns of the support legs corresponding to adjacent weight-reducing holes are arranged in different directions.

[0012] In the technical solution, by making the projection of the support leg on the body fall into the corresponding weight-reducing hole, the support leg is set to correspond to the weight-reducing hole, so that the support leg can effectively support the surrounding area of ​​the corresponding weight-reducing hole, thereby increasing the stiffness enhancement effect of the surrounding area of ​​the corresponding weight-reducing hole on the outer panel of the engine hood; by setting the projection pattern of the support leg corresponding to adjacent weight-reducing holes in different directions, the support leg is connected to the edge of different sides of the weight-reducing hole, so that the support leg is set in different directions in space, and the support leg can support the outer panel of the engine hood in different directions, thereby increasing the reinforcement effect of the support plate on the outer panel of the engine hood.

[0013] In some embodiments of this application, an adhesive application groove is provided between adjacent weight reduction holes, and the adhesive application groove is opened on the side of the body facing the outer panel of the engine hood; And / or, the body has an adhesive application groove on the side facing the outer panel of the engine hood, and there are multiple adhesive application grooves, with at least some of the adhesive application grooves located between adjacent weight reduction holes.

[0014] In the technical solution, an adhesive groove is provided between adjacent weight reduction holes to bond the outer periphery of the weight reduction holes to the outer panel of the engine hood, thereby increasing the rigidity enhancement effect of the area around the weight reduction holes on the outer panel of the engine hood.

[0015] In some embodiments of this application, one side of the support leg faces the body, and the other side is disposed away from the body; The supporting leg bends toward the body at its midpoint along its length to form a crumple zone.

[0016] In the technical solution, the middle part of the support leg is bent towards the body to form a crumple zone, so that the support leg bends and crumples in a set direction to reduce the stiffness of the support leg and avoid excessive stiffness of the engine hood outer panel, which could cause great injury to pedestrians in the event of a collision between a person and a vehicle.

[0017] In some embodiments of this application, the support leg is provided with reinforcing ribs extending along its length, and the reinforcing ribs are located on the side of the support leg facing the body.

[0018] In the technical solution, reinforcing ribs are added to the support legs to increase their rigidity, thereby enhancing the rigidity of the support plate on the outer panel of the engine hood. By placing the reinforcing ribs on the side of the support leg facing the main body, the ribs increase the rigidity of the support leg while ensuring that the crumple zone can collapse. If the reinforcing ribs are placed on the side of the support leg away from the main body, they will hinder the crumple zone from collapsing, reducing its reliability.

[0019] In some embodiments of this application, the support leg is made of cut material corresponding to the weight reduction hole; the length of the support leg is less than or equal to the distance between the two sides of the weight reduction hole.

[0020] In the technical solution, by using the material cut from the weight-reducing hole to make the support leg, the material utilization rate can be improved, the manufacturing cost of the support plate can be reduced, and the connection between the support leg and the edge of the weight-reducing hole can be facilitated. By making the length of the support leg less than or equal to the distance between the corresponding two edges of the weight-reducing hole, it is ensured that the size of the material cut from the weight-reducing hole can meet the manufacturing requirements of the support leg, and the size of the material cut is avoided.

[0021] Secondly, this application provides an engine hood assembly, comprising: Engine hood inner panel; Engine hood outer panel; A support plate is provided between the inner panel of the engine hood and the outer panel of the engine hood; the support plate is the aforementioned support plate for the outer panel of the engine hood.

[0022] In the technical solution, by connecting the inner panel and the outer panel of the engine hood through the aforementioned support plate, the engine hood assembly has good rigidity, enabling it to resist various loads and resist significant deformation. In the event of a collision, the support legs deform to absorb the collision energy, thereby reducing the impact force of the outer panel of the engine hood on pedestrians. Furthermore, since the body is equipped with weight-reducing holes, the overall mass of the engine hood assembly can be reduced while increasing its rigidity.

[0023] In some embodiments of this application, the end of the support leg away from the outer panel of the engine hood is provided with a connecting portion, which is used to contact the inner panel of the engine hood, and the two are in surface contact.

[0024] In the technical solution, by setting a connecting part on the support leg, the connecting part contacts the inner panel of the engine hood, thereby increasing the contact area between the support leg and the inner panel of the engine hood, increasing the supporting effect of the inner panel of the engine hood on the support plate, so that the support plate can support the outer panel of the engine hood, increasing the rigidity of the outer panel of the engine hood, and also preventing the impact force of the outer panel of the engine hood from being transmitted to the inner panel of the engine hood through the support plate, which would cause local stress concentration and deformation of the inner panel of the engine hood.

[0025] Thirdly, this application provides a vehicle, comprising: The vehicle body has an engine compartment with an opening. The engine hood assembly is connected to the vehicle body and covers the opening; Among them, the engine hood assembly is the aforementioned engine hood assembly.

[0026] In this technical solution, the aforementioned engine hood assembly is connected to the vehicle body, allowing it to protect the components inside the engine compartment from external impacts. In the event of a collision, the support legs deform to absorb the impact energy, reducing the impact force of the engine hood outer panel on pedestrians. Furthermore, due to the weight-reducing holes in the body, the overall weight of the engine hood assembly can be kept relatively small while maintaining good rigidity, thus reducing vehicle fuel consumption.

[0027] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0031] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. The engine hood is one of the important body parts at the front of a vehicle. It covers the engine compartment and serves to seal the engine compartment and protect the components inside.

[0032] An engine hood typically consists of an inner hood panel and an outer hood panel. The inner hood panel is located inside the outer hood panel, while the outer hood panel is located on the surface of the vehicle body. If the outer hood panel is not rigid enough, it may deform during a collision, affecting vehicle safety. However, if the outer hood panel is too rigid, it may cause significant injury to pedestrians during a collision.

[0033] In related technologies, a support plate is typically installed on the side of the outer hood panel facing the inner hood panel to increase the rigidity of the outer hood panel. Simultaneously, the support plate body is equipped with support legs, with one end of the support leg connected to the support plate body and the other end connected to the inner hood panel to support the outer hood panel. When the outer hood panel is subjected to a large load, the support legs deform, reducing the supporting effect on the outer hood panel and thus preventing excessive rigidity of the outer hood panel from causing significant injury to pedestrians.

[0034] To achieve the goal of vehicle lightweighting, weight reduction holes are often opened on the body of the support plate. Although opening weight reduction holes will reduce the weight of the support plate, it will also reduce the rigidity of the support plate itself. The support plate cannot effectively distribute and withstand the impact force from the outer panel of the hood. Furthermore, the weight reduction holes cannot enhance the rigidity of the outer panel of the hood, reducing the overall effect of the support plate on enhancing the rigidity of the outer panel of the hood. As a result, the support plate cannot well meet the rigidity enhancement requirements of the outer panel of the hood.

[0035] Based on this, this application proposes a support plate for an engine hood outer panel, an engine hood assembly, and a vehicle. By setting multiple weight-reducing holes 101 and placing support legs 2 at the weight-reducing holes 101, the support legs 2 support the engine hood outer panel to compensate for the loss of stiffness reinforcement to the engine hood outer panel caused by the weight-reducing holes 101 in the support plate body 1. Furthermore, the support legs 2 are arranged in different directions so that the support legs 2 can support the engine hood outer panel in different directions, thereby increasing the stiffness reinforcement effect of the support plate on the engine hood outer panel.

[0036] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0037] As attached Figures 1 to 5 As shown in an illustrative embodiment of the support plate for the outer panel of the engine hood, the engine hood assembly, and the vehicle of this application, the support plate for the outer panel of the engine hood is used to increase the rigidity of the outer panel of the engine hood. The support plate is located on the side of the outer panel of the engine hood facing the inner panel of the engine hood. The support plate for the outer panel of the engine hood includes a body 1 and support legs 2. The body 1 is connected to one side of the outer panel of the engine hood. The body 1 is provided with weight-reducing holes 101, and multiple weight-reducing holes 101 are provided, which are independently arranged. Multiple support legs 2 are provided, and the support legs 2 are corresponding to the weight-reducing holes 101. One end of the support leg 2 in the length direction is connected to... The other end of the support leg 2, which is attached to one side edge of the corresponding weight reduction hole 101, extends away from the main body 1 and is inclined toward the opposite side edge of the corresponding weight reduction hole 101. The support leg 2 is positioned at the weight reduction hole 101 to compensate for the loss of enhanced rigidity of the engine hood outer panel caused by the weight reduction hole 101 in the main body 1. At least some of the support legs 2 are connected to the edges of different sides of the corresponding weight reduction hole 101 so that the support legs 2 are arranged in different directions in space. This allows the support legs 2 to support the engine hood outer panel in different directions, thereby increasing the support effect of the support plate on the engine hood outer panel.

[0038] By creating weight-reduction holes 101 on the body 1, the weight of the body 1 can be reduced, thus achieving vehicle lightweighting. Compared with the prior art where the weight-reduction holes 101 are set as one or several large openings, in this application, the weight-reduction holes 101 are designed as multiple independently set small holes, which can better distribute the stress acting on the body 1 and also give the body 1 better structural rigidity, thereby ensuring the reinforcement effect of the body 1 on the outer panel of the engine hood.

[0039] It should be noted that since there is no interaction force between the main body 1 and the outer panel of the engine hood at the weight reduction hole 101, the weight reduction hole 101 cannot enhance the stiffness of the outer panel of the engine hood. This reduces the stiffness enhancement effect of the main body 1 on the outer panel of the engine hood, thereby reducing the stiffness enhancement effect of the support plate on the outer panel of the engine hood. In this application, the support leg 2 is located at the weight reduction hole 101 to compensate for the portion of stiffness enhancement lost by the weight reduction hole 101, thus ensuring the stiffness enhancement effect of the support plate on the outer panel of the engine hood.

[0040] For ease of description, in this embodiment, the enhanced stiffness refers to the stiffness of the engine hood outer panel. This stiffness is added to the engine hood outer panel due to the action of the support leg 2 or the body 1, and is not inherent to the engine hood outer panel itself. This is common knowledge in the field and will not be elaborated further.

[0041] like Figure 1 and Figure 4 As shown, the support leg 2 is inclined in space from the connection point with the edge of the weight reduction hole 101 away from the main body 1 and towards the other side edge of the weight reduction hole 101. When the outer panel of the engine hood is impacted, since the supporting force and the impact force on the outer panel are not on the same line, when the impact force is transmitted from the outer panel of the engine hood to the support leg 2, the support leg 2 can deform and crush to absorb the energy generated by the impact, thereby avoiding excessive stiffness of the outer panel of the engine hood and reducing the injury to pedestrians in the collision between people and vehicles.

[0042] It should be noted that setting the support leg 2 perpendicular to the outer panel of the hood has the best effect on enhancing the rigidity of the outer panel of the hood. However, this can lead to excessive rigidity of the outer panel of the hood. When the vehicle collides with a pedestrian, the outer panel of the hood is more likely to cause significant injury to the pedestrian. Therefore, the support leg 2 is usually set at an angle relative to the outer panel of the hood in space to balance the contradiction between the deformation of the outer panel of the hood and pedestrian protection.

[0043] In some embodiments, the support leg 2 is sheet-like or plate-like. When the support leg 2 is tilted in space, one side of the support leg 2 faces the body 1, and the other side is disposed away from the body 1.

[0044] Since the support leg 2 is inclined in space, the supporting force of the support leg 2 on the outer panel of the engine hood can be decomposed into a first component force and a second component force. The first component force is set in a direction perpendicular to the outer panel of the engine hood, and the second component force is set in the length direction of the body 1.

[0045] like Figure 1 , Figure 3 and Figure 4 As shown, multiple weight-reducing holes 101 are arranged along the length of the body 1. The support legs 2 corresponding to adjacent weight-reducing holes 101 are connected to the edges of different sides of the weight-reducing holes 101, so that the support legs 2 corresponding to two adjacent weight-reducing holes 101 are set in different directions in space, so that the engine hood outer panel is subjected to uniform force, thereby making the stiffness of the engine hood outer panel uniform and increasing the stiffness enhancement effect of the support plate on the engine hood outer panel.

[0046] In some embodiments, the weight reduction hole 101 is generally square and includes two pairs of opposing edges. One pair of edges is disposed opposite to each other in the width direction of the weight reduction hole 101 and extends along the length direction of the weight reduction hole 101, respectively. The other pair of edges is disposed opposite to each other in the length direction of the weight reduction hole 101 and extends along the width direction of the weight reduction hole 101, respectively.

[0047] It should be noted that among the multiple weight-reducing holes 101, some weight-reducing holes 101 are arranged along the length direction of the body 1, and some weight-reducing holes 101 are arranged along the width direction of the body 1.

[0048] It should also be noted that since there are multiple weight reduction holes 101 arranged along the length of the body 1, it can be assumed that the edge of each weight reduction hole 101 is set accordingly.

[0049] Taking a square weight-reducing hole 101, which includes a first edge, a second edge, a third edge, and a fourth edge, as an example, the meaning of different support legs 2 being connected to the edges of different sides of the corresponding weight-reducing hole 101 will be explained in detail. The first edge, second edge, third edge, and fourth edge are located on different sides of the weight-reducing hole 101. If a support leg 2 is connected to the first edge of the corresponding weight-reducing hole 101, then the adjacent support leg 2 will be connected to the second edge, third edge, or fourth edge of the corresponding weight-reducing hole 101, and will not be connected to the first edge of the corresponding weight-reducing hole 101.

[0050] like Figure 1 , Figure 3 and Figure 4As shown, multiple support legs 2 are arranged along the length of the body 1, and adjacent support legs 2 are connected to the edges of different sides of the corresponding weight reduction hole 101, so that adjacent support legs 2 are set in different directions in space, thereby enabling the support legs 2 to support the outer panel of the engine hood in different directions, so that the reinforcing stiffness of the outer panel of the engine hood is evenly distributed, thereby increasing the stiffness enhancement effect of the support plate on the outer panel of the engine hood.

[0051] In some weight-reducing holes 101, the two ends of the support leg 2 in the length direction are provided on opposite sides of the weight-reducing hole 101 in the width direction; in other weight-reducing holes 101, the two ends of the support leg 2 in the length direction are provided on opposite sides of the weight-reducing hole 101 in the length direction.

[0052] like Figure 3 As shown, the projection of the support leg 2 on the body 1 falls into the corresponding weight reduction hole 101, so that the support leg 2 is better positioned to correspond to the weight reduction hole 101, and the force path of the first component force on the outer panel of the engine hood passes through the weight reduction hole 101, so that the support leg 2 can effectively compensate for the lack of enhanced rigidity of the outer panel of the engine hood due to the weight reduction hole 101.

[0053] like Figure 3 As shown, the projected patterns of the support legs 2 corresponding to adjacent weight reduction holes 101 are arranged in different directions so that the support legs 2 are connected to the edges of the corresponding weight reduction holes 101 on different sides. This allows the support legs 2 to be arranged in different directions in space, so that the support legs 2 can support the outer panel of the engine hood in different directions, thereby increasing the reinforcement effect of the support plate on the outer panel of the engine hood.

[0054] Furthermore, such as Figure 3 As shown, in the projection pattern of the support leg 2 on the body 1, one end of the projection pattern is located at the edge of the weight reduction hole 101, and the other end of the projection pattern is located towards the opposite edge of the weight reduction hole 101 and inside the weight reduction hole 101, so that the contact point between the support leg 2 and the inner panel of the engine hood corresponds to the middle part of the weight reduction hole 101, so that the action path of the first component force on the outer panel of the engine hood can pass through the weight reduction hole 101, and the support leg 2 can effectively compensate for the loss of reinforcing stiffness of the weight reduction hole 101, and increase the reinforcing effect of the support plate on the outer panel of the engine hood.

[0055] The stiffness of the edge area of ​​the weight reduction hole 101 is low, especially the area around the edge of the weight reduction hole 101 that is not connected to the support leg 2. Not only is the stiffness of the edge area of ​​the weight reduction hole 101 itself low, but the effect of the edge area of ​​the weight reduction hole 101 on increasing the stiffness of the outer panel of the engine hood is also weak. In this application, by setting the glue application groove 102 in the edge area of ​​the weight reduction hole 101, the edge area of ​​the weight reduction hole 101 is connected to the outer panel of the engine hood, thereby increasing the stiffness enhancement effect of the edge area of ​​the weight reduction hole 101 on the outer panel of the engine hood.

[0056] like Figure 1 As shown, an adhesive groove 102 is provided between adjacent weight reduction holes 101. The adhesive groove 102 is opened on the side of the body 1 facing the outer panel of the engine hood. Expanding adhesive is applied in the adhesive groove 102 to fill the gap between the body 1 and the outer panel of the engine hood, so as to prevent the outer panel of the engine hood from shifting relative to the body 1, thereby increasing the stiffness enhancement effect of the edge area of ​​the weight reduction hole 101 on the outer panel of the engine hood, and thus increasing the stiffness of the outer panel of the engine hood.

[0057] In other words, the body 1 has an adhesive groove 102 on the side facing the outer panel of the engine hood. There are multiple adhesive grooves 102, and at least some of the adhesive grooves 102 are located between adjacent weight reduction holes 101 to fill the gap between the edge area of ​​the weight reduction hole 101 and the outer panel of the engine hood, so as to prevent the outer panel of the engine hood from shifting relative to the body 1, thereby increasing the rigidity of the outer panel of the engine hood.

[0058] Since the weight reduction holes 101 are arranged along the length of the body 1, and the glue application groove 102 is located between adjacent weight reduction holes 101, in some embodiments, the glue application groove 102 extends along the width of the body 1 so that there is a larger glue application area between the body 1 and the outer panel of the engine hood, thereby making the body 1 and the outer panel of the engine hood better connected.

[0059] In other embodiments, such as Figure 3 As shown, some of the adhesive application grooves 102 are located at the edge of the weight reduction holes 101 but not between adjacent weight reduction holes 101. That is, these adhesive application grooves 102 extend along the length of the body 1 and are located on one side of the width of the body 1. By also providing adhesive application grooves 102 on the outer periphery of one of the edges of the weight reduction holes 101 that are opposite to each other along the width of the body 1, the filling effect of the expanding adhesive on the gap between the body 1 and the outer panel of the engine hood is increased.

[0060] In some alternative embodiments, the adhesive applicator 102 is formed on the body 1 by stamping, such as... Figure 4 As shown, the main body 1 has a protrusion 103 on the side opposite to the outer panel of the engine hood, which corresponds to the glue application groove 102. The stamping method can improve the production efficiency of the glue application groove 102.

[0061] like Figure 2 As shown, the support leg 2 bends toward the body 1 at the middle part in its length direction to form a collapsible portion 24; the collapsible portion 24 allows the support leg 2 to bend and collapse in a set direction to reduce the stiffness of the support leg 2 and avoid excessive stiffness of the engine hood outer panel, which could cause significant injury to pedestrians in the event of a collision between a person and a vehicle.

[0062] like Figure 2As shown, the collapsible portion 24 divides the support leg 2 into two parts, one part being located close to the main body 1 and the other part being located away from the main body 1 and close to the inner panel of the engine hood; the two parts of the support leg 2 are arranged along the length of the support leg 2. For ease of description, the part of the support leg 2 close to the main body 1 is referred to as the first part 21, and the part of the support leg 2 away from the main body 1 is referred to as the second part 22.

[0063] The first part 21 and the second part 22 have different tilt angles to reduce the load-bearing effect of the support leg 2, thereby reducing the enhancement effect of the support plate on the rigidity of the engine hood outer plate.

[0064] In some embodiments, the tilt angle of the first part 21 is smaller than the tilt angle of the second part 22. When the body 1 is subjected to a load, the support leg 2 is more likely to deform toward the center of the weight reduction hole 101 to absorb energy.

[0065] In some other embodiments, the tilt angle of the first part 21 is greater than that of the second part 22. When the body 1 is subjected to load, the support leg 2 is more likely to deform away from the center of the weight reduction hole 101 to absorb energy.

[0066] It should be noted that the plane perpendicular to the body 1 and passing through the length direction of the body 1 is the reference plane, the angle between the first part 21 and the reference plane is the tilt angle of the first part 21, and the angle between the second part 22 and the reference plane is the tilt angle of the second part 22. This is a conventional technical means in this field and will not be described in detail.

[0067] like Figure 2 As shown, the support leg 2 is provided with a reinforcing rib 201 extending along its length direction. The reinforcing rib 201 extends along the length direction of the support leg 2 to increase the rigidity of the support leg 2, prevent irreversible deformation of the support leg 2, increase the service life of the support leg 2, and also increase the support effect of the support leg 2 on the outer panel of the engine hood, thereby increasing the rigidity of the outer panel of the engine hood.

[0068] The reinforcing rib 201 is provided on the side of the support leg 2 facing the body 1, so that the reinforcing rib 201 increases the rigidity of the support leg 2 while ensuring that the collapsible part 24 can collapse. If the reinforcing rib 201 is provided on the side of the support leg 2 away from the body 1, the reinforcing rib 201 will hinder the collapse of the collapsible part 24 and reduce the reliability of the collapsible part 24.

[0069] In some embodiments, the reinforcing rib 201 is formed by stamping, such as... Figure 5As shown, the support leg 2 is provided with a groove 202 corresponding to the reinforcing rib 201, and the groove 202 is located on the side of the support leg 2 away from the body 1. The reinforcing rib 201 is formed by stamping, which can increase the rigidity of the support leg 2 without increasing the weight of the support leg 2. Moreover, the stamping method is simple and easy to operate, and the production efficiency of the reinforcing rib 201 is high.

[0070] like Figure 2 and Figure 5 As shown, the end of the support leg 2 away from the outer panel of the engine hood is provided with a connecting part 23. The connecting part 23 is used to contact the inner panel of the engine hood, and the two are in surface contact to increase the contact area between the support leg 2 and the inner panel of the engine hood, thereby increasing the supporting effect of the inner panel of the engine hood on the support plate. This allows the support plate to support the outer panel of the engine hood, increasing the rigidity of the outer panel of the engine hood. It also prevents the impact force of the outer panel of the engine hood from being transmitted to the inner panel of the engine hood through the support plate, which would cause local stress concentration in the inner panel of the engine hood and lead to deformation of the inner panel of the engine hood.

[0071] In some embodiments, the connecting portion 23 is located on the side of the support leg 2 facing the body 1.

[0072] In some embodiments of this application, the support leg 2 is made from the material cut from the corresponding weight-reducing hole 101. While the weight-reducing hole 101 is being created by cutting the body 1, the support leg 2 can be made from the material cut from the body. This not only facilitates the connection between the support leg 2 and the body 1, but also improves material utilization and reduces the manufacturing cost of the support plate. The length of the support leg 2 is less than or equal to the distance between the two sides of the corresponding weight-reducing hole 101 to ensure that the size of the material cut from the weight-reducing hole 101 meets the manufacturing requirements of the support leg 2, avoiding insufficient material size.

[0073] Since the support leg 2 is provided with a corresponding weight reduction hole 101 and the support leg 2 is connected to the edge of the corresponding weight reduction hole 101, the material utilization rate can be improved and the manufacturing cost of the support plate can be reduced by using the material cut from the weight reduction hole 101 to make the support leg 2. It can also facilitate the connection between the support leg 2 and the edge of the weight reduction hole 101.

[0074] In some embodiments of this application, the body 1 and the support leg 2 are integral sheet metal parts. The body 1 and the support leg 2 are made from the same sheet metal. While cutting the body 1 to generate the weight reduction hole 101, the cutting material is used to cut the substrate for making the support leg 2. The reinforcing rib 201 is formed by stamping on the substrate. Then the substrate is bent away from the body 1, and the middle part of the substrate is bent to form the collapsing part 24 and the end of the substrate away from the body 1 is bent to form the connecting part 23, so as to finally form the support leg 2.

[0075] Other types of high-rigidity materials, such as titanium alloys, can be used for the support plate, but titanium alloys are relatively more expensive than sheet metal parts.

[0076] It should be noted that the shape of the support plate and the position of the support leg 2 can be optimized in different ways, but a new collision test may be required to verify the effect.

[0077] Based on the aforementioned support plate for the outer panel of the engine hood, this application provides an engine hood assembly, including an inner panel of the engine hood, an outer panel of the engine hood, and a support plate; the support plate is disposed between the inner panel of the engine hood and the outer panel of the engine hood; the support plate is the aforementioned support plate for the outer panel of the engine hood.

[0078] By connecting the inner and outer panels of the engine hood through the aforementioned support plate, the engine hood assembly has good rigidity, enabling it to resist various loads and resist significant deformation. In the event of a collision, the support leg 2 deforms to absorb the collision energy, thereby reducing the impact force of the outer panel of the engine hood on pedestrians. Furthermore, since the body 1 is provided with weight reduction holes 101, the overall mass of the engine hood assembly can be reduced while increasing its rigidity.

[0079] Based on the above-described engine hood assembly, this application provides a vehicle including a body and an engine hood assembly; the body has an engine compartment with an opening, and an engine is installed in the engine compartment; the engine hood assembly is connected to the body and covers the opening; the engine hood assembly is the aforementioned engine hood assembly.

[0080] The aforementioned engine hood assembly is connected to the vehicle body, enabling it to protect the components inside the engine compartment from external impacts. In the event of a collision, the support legs 2 deform to fully absorb the collision energy, reducing the impact force of the engine hood outer panel on pedestrians. This effectively improves the rigidity of the engine hood outer panel without sacrificing pedestrian protection. Furthermore, because the body 1 has weight-reduction holes 101, the overall weight of the engine hood assembly is reduced while maintaining good rigidity, thus lowering vehicle fuel consumption. This not only improves vehicle safety performance but also aligns with the lightweight design trend of modern vehicles.

[0081] In practical applications, the length of the body 1 is preferably set along the left-right direction of the vehicle, and the width of the body 1 is preferably set along the front-back direction of the vehicle.

[0082] A Cartesian coordinate system is established on the vehicle, with the x-axis defined by the left-right direction of the vehicle, the y-axis defined by the front-back direction of the vehicle, and the z-axis defined by the height direction of the vehicle. In the Cartesian coordinate system, some support legs 2 are set along the xz direction and some support legs 2 are set along the yz direction, so that multiple support legs 2 can support the outer panel of the engine hood in different directions, thereby increasing the rigidity of the outer panel of the engine hood.

[0083] It should be noted that in some embodiments, the support plate is located at the rear of the outer hood panel to increase the rigidity of the rear of the outer hood panel. The rear of the outer hood panel is the end of the outer hood panel furthest from the front of the vehicle.

[0084] Through the description of several embodiments of the support plate for the outer panel of the engine hood, the engine hood assembly, and the vehicle of this application, it can be seen that the support plate for the outer panel of the engine hood, the engine hood assembly, and the vehicle of this application have at least one or more of the following advantages: 1. By setting the weight reduction hole 101 as multiple small holes, the body 1 can have higher rigidity while reducing the same weight, thus ensuring the rigidity enhancement effect of the support plate on the outer panel of the engine hood.

[0085] 2. By placing the support leg 2 at the weight reduction hole 101 and making the projection of the support leg 2 on the body 1 at the end connected to the inner panel of the engine hood located inside the weight reduction hole 101, the support leg 2 is used to compensate for the loss of the reinforcing stiffness of the outer panel of the engine hood due to the weight reduction hole 101, thereby increasing the stiffness enhancement effect of the support plate on the outer panel of the engine hood.

[0086] 3. By arranging the support legs 2 in different directions in space, the support legs 2 can provide support to the outer panel of the engine hood in different directions, thereby increasing the support effect of the support plate on the outer panel of the engine hood and thus increasing the rigidity of the outer panel of the engine hood.

[0087] 4. By arranging the support legs 2 corresponding to adjacent weight reduction holes 101 in different directions in space, the supporting force of the support legs 2 on the outer panel of the engine hood is evenly distributed on the outer panel of the engine hood, ensuring uniform rigidity of the outer panel of the engine hood, thereby increasing the reinforcing effect of the support plate on the outer panel of the engine hood.

[0088] 5. The support leg 2 is made from the material cut from the weight-reducing hole 101. While the weight-reducing hole 101 is generated by cutting the body 1, the support leg 2 is made from the material cut. This not only makes it easier for the support leg 2 to connect with the body 1, but also improves the material utilization rate and reduces the manufacturing cost of the support plate.

[0089] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
