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 hood outer panel is one of the important body parts at the front of the vehicle. When designing the hood outer panel, it is necessary to balance the contradiction between its own rigidity and pedestrian safety protection in the event of a collision. If the rigidity of the hood outer panel is insufficient, it may deform in the event of a collision, affecting vehicle safety. However, if the rigidity of the hood outer panel is too great, it may cause greater injury to pedestrians in the event of a collision.

[0003] Some engine hood outer panels have support plates on the inside, and support legs are installed on the support plates. One end of the support leg is connected to the support plate, and the other end of the support leg is connected to the inner panel of the engine hood. This increases the rigidity of the engine hood outer panel while preventing it from becoming too rigid, thus better balancing the contradiction between the rigidity of the engine hood outer panel and pedestrian safety protection during a collision.

[0004] In the existing technology, the support legs are usually set on the outer edge of the support plate. In the production process, in addition to the plate material required for the support plate itself, additional plate material is required to make the support legs, which not only increases the amount of material used, but also increases the overall manufacturing cost. 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 using cut material with weight-reducing holes to make support legs, thereby improving material utilization and reducing the manufacturing cost of the support plate.

[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 weight reduction holes; The support leg has one end connected to one side edge of the weight reduction hole along its length, and the other end extends away from the outer panel of the engine hood. The two ends of the support leg along its length are positioned opposite the two sides of the weight reduction hole, and the length of the support leg is less than or equal to the distance between the two sides of the weight reduction hole.

[0008] In the technical solution, the rigidity of the outer hood panel is increased by connecting the main body to the side of the outer hood panel facing the inner hood panel. Support legs are installed on the main body, with one end connected to the main body and the other end extending away from the outer hood panel and connecting to the inner hood panel. This reduces the overall rigidity of the support plate, thereby reducing its effect on the rigidity of the outer hood panel. This allows the outer hood panel to better balance its own rigidity with pedestrian safety during a collision, preventing excessive rigidity from causing damage during a vehicle collision. This design aims to prevent pedestrian injuries and avoid insufficient rigidity of the engine hood outer panel, which could lead to deformation during a vehicle collision and compromise vehicle safety. Weight-reducing holes are incorporated into the main body to lower its weight, facilitating vehicle lightweighting. Furthermore, by aligning the two ends of the support legs along their length with the opposite edges of the weight-reducing holes, and ensuring the length of the support legs is less than or equal to the distance between the opposite edges of the weight-reducing holes, the support legs can be fabricated using the cut material while the main body is being cut to create the weight-reducing holes. This not only facilitates the connection between the support legs and the main body but also improves material utilization and reduces the manufacturing cost of the support plate.

[0009] In some embodiments of this application, the support leg is made of material cut from a material with weight-reducing holes.

[0010] In the technical solution, the support legs can be made by using the material cut from the weight-reducing holes, which can improve the material utilization rate, reduce the manufacturing cost of the support plate, and facilitate the connection between the support legs and the edge of the weight-reducing holes.

[0011] In some embodiments of this application, the length direction of the support leg corresponds to the length direction of the material to be cut through the weight reduction hole, and the length of the support leg is less than or equal to the length of the material to be cut through the weight reduction hole. And / or, the two ends of the support leg in the length direction correspond one-to-one with the two sides of the weight reduction hole that are set opposite to each other in the length direction of the weight reduction hole.

[0012] In the technical solution, by aligning the length direction of the support leg with the length direction of the cutting material, and ensuring that the length of the support leg is less than or equal to the length of the cutting material, the size of the cutting material for the weight-reducing hole can meet the manufacturing requirements of the support leg, thus avoiding insufficient cutting material size. Furthermore, by aligning the two ends of the support leg with the two opposite edges of the weight-reducing hole along its length direction, the length direction of the support leg is approximately aligned with the length direction of the weight-reducing hole, thereby ensuring that the size of the cutting material for the weight-reducing hole can meet the manufacturing requirements of the support leg, thus avoiding insufficient cutting material size.

[0013] In some embodiments of this application, multiple weight-reducing holes are provided, and at least some of the weight-reducing holes are respectively connected to support legs on their opposite sides in the length direction. And / or, the support legs are configured as multiple, with at least two support legs alternately connected to the opposite sides of the same weight reduction hole.

[0014] In the technical solution, support legs are connected to the two opposite edges of the weight-reducing hole along its length, so that the load can be shared on both sides of the weight-reducing hole, avoiding uneven force on both sides of the weight-reducing hole. By setting multiple support legs, with at least two support legs alternately connected to the opposite edges of the same weight-reducing hole, the load on the body can be distributed to multiple support legs, preventing deformation or damage to a single support leg due to excessive force, thereby increasing the reliability of the support plate for the outer panel of the engine hood. When one support leg is damaged, the other support legs can continue to share the load, preventing a sharp drop in the stiffness of the outer panel of the engine hood due to the failure of a single support leg, thus improving the fault tolerance and overall reliability of the support plate structure.

[0015] In some embodiments of this application, the two support legs corresponding to the same weight reduction hole are staggered along the width direction of the body.

[0016] In the technical solution, by arranging the two support legs corresponding to the same weight reduction hole staggered along the width direction of the body, the two support legs are not on the same straight line along the length direction of the body and have no overlapping area, so that the cutting material of the same weight reduction hole can be used to make two support legs at the same time, avoiding the overlap of the cutting material required for the two support legs.

[0017] In some embodiments of this application, the end of the support leg away from the body is inclined toward the middle part of the weight reduction hole; And / or, the projection of the support leg onto the body falls into the weight reduction hole.

[0018] In the technical solution, by tilting the end of the support leg away from the main body toward the middle part of the weight reduction hole, and / or by having the projection of the support leg on the main body fall into the weight reduction hole, the length direction of the support leg is tilted relative to the surface of the main body, thereby reducing the support effect of the support leg on the main body and the inner panel of the engine hood, and thus avoiding excessive rigidity of the outer panel of the engine hood.

[0019] In some embodiments of this application, the middle part of the support leg is provided with a collapsible portion, which divides the support leg into two parts. The two parts of the support leg are arranged along the length direction of the support leg, and the two parts of the support leg have different inclination angles.

[0020] In the technical solution, by setting a crumple zone in the middle part of the support leg, the two parts of the support leg are tilted at different angles, thereby reducing the overall strength of the support leg, thus reducing the load-bearing capacity of the support leg, and consequently reducing the enhancement effect of the support plate on the rigidity of the engine hood outer panel.

[0021] In some embodiments of this application, the body has an adhesive application groove on the side facing the outer panel of the engine hood, and the adhesive application groove is located on the outer periphery of the weight reduction hole.

[0022] In the technical solution, an adhesive application groove is set on the main body, and an expanding adhesive is applied in the adhesive application groove to fill the gap between the main body and the outer panel of the engine hood, thereby increasing the rigidity of the outer panel of the engine hood.

[0023] 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.

[0024] 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.

[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 has 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 to reduce the supporting effect on the outer hood panel, thereby preventing excessive rigidity of the outer hood panel from causing significant injury to pedestrians. While this method can effectively balance the contradiction between the rigidity of the outer hood panel and pedestrian safety protection during a collision, in existing technologies, the support legs are usually located on the outer edge of the support plate. During the production process, in addition to the sheet metal required for the support plate itself, extra sheet metal is needed to make the support legs, thus increasing both material usage and overall manufacturing costs.

[0034] Based on this, this application proposes a support plate for the outer panel of the engine hood, an engine hood assembly, and a vehicle. The support leg 2 is made by using the cut material that generates the weight reduction hole 101 to improve material utilization and reduce the manufacturing cost of the support plate.

[0035] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0036] 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 in 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 a support leg 2. The body 1 is connected to one side of the outer panel of the engine hood. The body 1 is provided with a weight reduction hole 101 to reduce the weight of the body 1. The weight reduction hole 101 is formed by cutting the body 1. One end of the support leg 2 along its length is connected to one side edge of the weight reduction hole 101, and the other end of the support leg 2 along its length extends away from the outer panel of the engine hood. The two ends of the support leg 2 along its length are set on opposite sides of the weight reduction hole 101. The length of the support leg 2 is less than or equal to the distance between the opposite sides of the weight reduction hole 101. This allows the support leg 2 to be made using the cut material while the weight reduction hole 101 is being generated by cutting the body 1. 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.

[0037] In some embodiments, such as Figures 1-3As shown, multiple weight-reducing holes 101 are provided, and the multiple weight-reducing holes 101 are arranged along the length direction of the body 1 to increase the weight reduction effect of the body 1; the multiple weight-reducing holes 101 are set independently and do not interfere with each other to ensure the strength of the body 1, thereby effectively reducing the weight of the body 1 while ensuring the strength of the body 1.

[0038] Preferably, such as Figure 1 As shown, the weight reduction hole 101 is located in the middle part of the body 1. The weight reduction hole 101 is a closed hole so as to ensure the rigidity of the body 1 while reducing the weight of the body 1.

[0039] 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.

[0040] The length direction of the support leg 2 corresponds to the length direction of the cutting material of the weight reduction hole 101. The length of the support leg 2 is less than or equal to the length of the cutting material of the weight reduction hole 101, so that the size of the cutting material of the weight reduction hole 101 can meet the manufacturing requirements of the support leg 2, and avoid the inability to manufacture the support leg 2 due to insufficient cutting material size.

[0041] like Figure 1 and Figure 2 As shown, the two ends of the support leg 2 in the length direction correspond one-to-one with the two sides of the weight reduction hole 101 that are opposite to each other in the length direction of the weight reduction hole 101, so that the length direction of the support leg 2 corresponds to the length direction of the weight reduction hole 101, thereby ensuring that the size of the cutting material of the weight reduction hole 101 can meet the manufacturing requirements of the support leg 2, and avoiding the inability to manufacture the support leg 2 due to insufficient cutting material size.

[0042] like Figures 1-3 As shown, the weight-reducing holes 101 are arranged on both sides of their length direction and correspond one-to-one with the two ends of the support leg 2, so that the length direction of the support leg 2 is roughly along the length direction of the weight-reducing holes 101, thereby ensuring that the size of the material cut by the weight-reducing holes 101 can meet the manufacturing size requirements of the support leg 2.

[0043] It should be noted that the weight-reducing hole 101 is square, and the corresponding cutting material is also oriented. The length direction of the cutting material is the same as the length direction of the weight-reducing hole 101, and the width direction of the cutting material is the same as the width direction of the weight-reducing hole 101. The length direction of the cutting material is relatively large. By setting the length direction of the support leg 2 approximately along the length direction of the weight-reducing hole 101, the length direction of the support leg 2 is set to correspond with the length direction of the cutting material, so that the cutting material has sufficient size to make the support leg 2.

[0044] If the dimensions of the cut material in the length direction cannot meet the manufacturing requirements of the support leg 2, then the dimensions of the cut material in other directions will also be difficult to meet the manufacturing requirements of the support leg 2.

[0045] In some embodiments, the width of the weight-reducing hole 101 is set along the width of the body 1, and the length of the weight-reducing hole 101 is set along the length of the body 1. That is, the length direction of the support leg 2 is set approximately along the length direction of the body 1.

[0046] In other embodiments, the width of the weight-reducing hole 101 is set along the length direction of the body 1, and the length of the weight-reducing hole 101 is set along the width of the body 1. That is, the length direction of the support leg 2 is set approximately along the width direction of the body 1.

[0047] like Figures 1-3 As shown, at least some of the weight-reducing holes 101 are connected to support legs 2 on their opposite sides along their length direction, so that support legs 2 on both sides of the weight-reducing hole 101 along its length direction can share the load and avoid uneven force on both sides of the weight-reducing hole 101.

[0048] It should be noted that the main body 1 typically has multiple weight-reducing holes 101, but not all the material cut from the weight-reducing holes 101 needs to be used to make support legs 2. Too many support legs 2 can easily lead to excessive support for the engine hood outer panel, resulting in excessive rigidity of the engine hood outer panel. The number and placement of the support legs 2 usually need to be verified through crash tests and experiments to ensure the reinforcement effect of the support plate on the engine hood outer panel.

[0049] like Figures 1-3 As shown, multiple support legs 2 are provided so that the load on the main body 1 can be distributed to multiple support legs 2, avoiding deformation or damage to a single support leg 2 due to excessive force, thereby increasing the support effect of the support plate on the outer panel of the engine hood; and when a support leg 2 is damaged, the other support legs 2 can continue to share the load on the main body 1, avoiding a sharp drop in the stiffness of the outer panel of the engine hood due to the failure of a single support leg 2, thus improving the fault tolerance and operational reliability of the support plate.

[0050] In some embodiments, such as Figures 1-4 As shown, at least two support legs 2 are alternately connected to the opposite sides of the same weight reduction hole 101, so that the opposite sides of the weight reduction hole 101 are supported by support legs 2, thereby balancing the force on the body 1 and the support legs 2 and ensuring the support effect of the support plate on the outer panel of the engine hood.

[0051] Preferred, such as Figure 2As shown, the two support legs 2 corresponding to the same weight reduction hole 101 are staggered along the width direction of the weight reduction hole 101 so that the two support legs 2 are not on the same straight line along the length direction of the body 1 and have no overlapping area, so that the cutting material can be used to make two support legs 2 at the same time, avoiding the overlap of the cutting material required for the two support legs 2.

[0052] If the two support legs 2 are located on the same straight line or at least partially overlap along the length of the body 1, the required cutting material for the two support legs 2 will overlap. Since there is only one set of cutting material, one support leg 2 will not be able to be manufactured smoothly due to a lack of cutting material.

[0053] like Figure 4 As shown, the end of the support leg 2 furthest from the main body 1 is inclined toward the middle part of the weight reduction hole 101, so that the support leg 2 is inclined relative to the main body 1, thereby reducing the supporting effect of the support leg 2 on the main body 1 and the inner panel of the engine hood. 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, and the angle between the support leg 2 and the main body 1 changes to absorb the energy generated by the impact.

[0054] It should be noted that since the two support legs 2 are alternately connected to the opposite sides of the same weight reduction hole 101, the two support legs 2 corresponding to the same weight reduction hole 101 have different inclination directions. This design not only makes full use of the cut material to make support legs 2, but also makes support legs 2 less prone to collapse deformation when subjected to load, thereby increasing the support effect on the outer panel of the engine hood.

[0055] like Figure 2 As shown, the projection of the support leg 2 on the body 1 falls into the weight reduction hole 101, so that the support leg 2 is tilted relative to the body 1, thereby reducing the support effect of the support leg 2 on the body 1 and the inner panel of the engine hood.

[0056] It should be noted that, as Figure 2 As shown, the weight reduction hole 101 is defined by a center line 105, which extends along the width direction of the weight reduction hole 101. The projections of the ends of the two support legs 2 corresponding to the same weight reduction hole 101 away from the body 1 are located on both sides of the center line 105, so as to avoid mutual obstruction when the two support legs 2 deform, and to avoid the two support legs 2 forming mutual support to increase the support effect on the outer panel of the engine hood, thereby avoiding the outer panel of the engine hood having a large rigidity.

[0057] like Figure 3As shown, the middle portion of the support leg 2 is provided with a crumple zone 22 to reduce the overall strength of the support leg 2. The crumple zone 22 divides the support leg 2 into two parts, one part being located close to the body 1 and the other part being located away from the 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 direction of the support leg 2. For ease of description, the part of the support leg 2 close to the body 1 is referred to as the first part 201, and the part of the support leg 2 away from the body 1 is referred to as the second part 202.

[0058] The first part 201 and the second part 202 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.

[0059] like Figure 5 As shown, a straight line perpendicular to the body 1 is defined as a reference straight line 106, and a plane perpendicular to the body 1 and passing through the length direction of the body 1 is defined as a reference plane; the first part 201 is defined to form a first straight line 203 arranged along its length direction, and the angle α between the projection of the first straight line 203 and the reference straight line 106 onto the reference plane is the tilt angle of the first part 201; the second part 202 is defined to form a second straight line 204 arranged along its length direction, and the angle β between the projection of the second straight line 204 and the reference straight line 106 onto the reference plane is the tilt angle of the second part 202.

[0060] In some embodiments, the tilt angle of the first part 201 is smaller than the tilt angle of the second part 202. 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.

[0061] In some other embodiments, the tilt angle of the first part 201 is greater than that of the second part 202. 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.

[0062] like Figure 2 As shown, the support leg 2 is provided with a reinforcing rib 21, which extends along the length of the support leg 2 to increase the strength 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.

[0063] In some embodiments, the reinforcing rib 21 is formed by stamping. One side of the support leg 2 is provided with the reinforcing rib 21, and the other side of the support leg 2 is provided with a groove 24 corresponding to the reinforcing rib 21. By forming the reinforcing rib 21 by stamping, the strength of the support leg 2 can be increased 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 21 is high.

[0064] like Figure 2 As shown, the reinforcing rib 21 is located on the side of the support leg 2 facing the center of the weight reduction hole 101, and the groove 24 is located on the side of the support leg 2 away from the center of the weight reduction hole 101.

[0065] In some alternative embodiments, the reinforcing rib 21 is located on the side of the support leg 2 away from the center of the weight reduction hole 101, and the groove 24 is located on the side of the support leg 2 facing the center of the weight reduction hole 101.

[0066] like Figure 2 and Figure 3 As shown, the end of the support leg 2 away from the main body 1 is provided with a connecting part 23, which is welded to the inner panel of the engine hood.

[0067] In some embodiments, the connecting part 23 makes surface contact with the inner panel of the engine hood, which not only facilitates the connection between the support leg 2 and the inner panel of the engine hood, but also increases the contact area between the support leg 2 and the inner panel of the engine hood.

[0068] The support leg 2 is made from the material cut from the weight reduction hole 101, which not only improves the utilization rate of materials and reduces the manufacturing cost of the support plate, but also facilitates the connection between the support leg 2 and the edge of the weight reduction hole 101.

[0069] 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 21 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 a collapsing part 22 and the end of the substrate away from the body 1 is bent to form a connecting part 23, so as to finally form the support leg 2.

[0070] In some embodiments, the sheet metal parts are made of lightweight, high-strength materials and have a thickness of 0.65 mm to reduce the overall weight of the support plate while ensuring its overall strength.

[0071] In other embodiments of this application, the support plate may be made of other types of high-strength materials, such as carbon fiber composites, but carbon fiber composites are relatively more expensive than sheet metal parts.

[0072] like Figure 1 and Figure 2 As shown, the body 1 has an adhesive groove 102 on the side 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 rigidity of the outer panel of the engine hood.

[0073] like Figure 1 and Figure 2 As shown, there are multiple glue application grooves 102, at least some of which extend along the length direction of the body 1 and at least some of which extend along the width direction of the body 1, in order to increase the filling effect of the expanding glue on the gap between the body 1 and the outer panel of the engine hood.

[0074] In some embodiments, the adhesive groove 102 is located on the outer periphery of the weight reduction hole 101 to increase the filling effect of the expanding adhesive on the gap between the body 1 and the outer panel of the engine hood.

[0075] like Figure 1 and Figure 2 As shown, the main body 1 is provided with a positioning hole 103, which is used to position the connection between the main body 1 and the outer panel of the engine hood.

[0076] Preferably, there are two positioning holes 103, which are arranged along the length of the body 1 to better position the connection between the body 1 and the outer panel of the engine hood.

[0077] In some embodiments, such as Figure 1 As shown, the main body 1 is provided with an extension 104, which is located at the edge of the weight reduction hole 101, and the positioning hole 103 is provided on the extension 104.

[0078] The extension 104 is positioned away from the support leg 2 and the glue application groove 102 to avoid the support leg 2 and the expanding glue affecting the positioning effect of the positioning hole 103, and also to avoid the positioning hole 103 affecting the function of the support leg 2 and the expanding glue.

[0079] 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.

[0080] It should also be noted that other design schemes can be adopted for energy absorption and dispersion mechanisms, such as adding energy-absorbing foam, but this may affect the stiffness of the support plate.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Establish a Cartesian coordinate system on the vehicle, with the x-axis defined by the left and right directions of the vehicle, the y-axis defined by the front and rear directions of the vehicle, and the z-axis defined by the height of the vehicle. The support leg 2 is set along the xz direction.

[0087] 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.

[0088] 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 connecting the main body 1 to the outer panel of the engine hood, and connecting one end of the support leg 2 to the main body 1 and the other end to the inner panel of the engine hood, the rigidity of the outer panel of the engine hood is increased. At the same time, it can avoid excessive rigidity of the outer panel of the engine hood from causing great injury to pedestrians in a collision, thus effectively solving the contradiction between the rigidity of the outer panel of the engine hood and pedestrian protection.

[0089] 2. The support leg 2 is set along the xz direction so that the support leg 2 supports the outer panel of the engine hood in the xz direction, which can not only increase the rigidity of the outer panel of the engine hood, but also increase the torsional rigidity of the engine hood assembly.

[0090] 3. The support plate is made of thin plate, and a large weight reduction hole 101 is set in the body 1. This can ensure that while enhancing the rigidity of the outer plate of the engine hood, the vehicle weight will not be significantly increased, thus avoiding an increase in vehicle fuel consumption.

[0091] 4. The two ends of the support leg 2 are set on opposite sides of the weight reduction hole 101, so that while the weight reduction hole 101 is generated by cutting the body 1, the support leg 2 can be made using the cut material. This not only facilitates the connection between the support leg 2 and the body 1, but also improves the material utilization rate and reduces the manufacturing cost of the support plate.

[0092] 5. By designing a crumple zone 22 in the middle of the support leg 2, the support leg 2 can effectively absorb and disperse energy in the event of a collision, reducing injury to pedestrians and improving pedestrian protection performance.

[0093] 6. The support plate is made of lightweight and high-strength materials, which not only ensures the structural strength of the support plate, but also avoids a significant increase in vehicle weight, realizing the lightweight design of the vehicle and improving the vehicle's fuel efficiency and overall performance.

[0094] 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.
