[0045] The term "multiple" as used in this application refers to two or more (including two). Similarly, "multiple groups" refers to two or more groups (including two groups), and "multiple pieces" refers to two or more pieces (including two pieces).

[0046] It should be noted that with the rapid development of the automotive industry, more and more automobile manufacturers integrate and install the front bumper structure on the front end of the engine hood. This installation method requires the engine hood to have strong structural strength. However, too high a structural strength of the engine hood is not conducive to pedestrian protection during a collision. Therefore, how to improve the pedestrian protection performance of the vehicle while ensuring the strength of the engine hood has become a technical problem that urgently needs to be solved today.

[0047] Based on this, the present application proposes an engine hood assembly 100. The first mounting surface 21 of the mounting plate 2 is spaced apart from the second mounting surface 22 along the first direction X, and along the second direction Y, the first mounting surface 21 is provided at the lower end of the second mounting surface 22. The first mounting surface 21 is connected to the second mounting surface 22 through the first connecting surface 23. In this way, the mounting plate 2 is integrally in a bent structure, which is beneficial to improving the strength of the mounting plate 2, and further ensures the overall strength of the engine hood assembly 100. At the same time, the first mounting portion 32 of the mounting bracket 3 is fixedly installed on the first mounting surface 21 of the mounting plate 2 through the first supporting portion 31. The front bumper skin is fixedly installed on the vehicle body through the first mounting surface 21 and the first mounting portion 32. The first supporting portion 31 has a first crushable portion 311 that can be crushed and deformed along the first direction X. When the front bumper structure of the vehicle collides with a pedestrian, the first supporting portion 31 can be crushed and deformed along the first direction X to absorb energy, thereby increasing the crush space of the front bumper structure, which is beneficial to reducing the injury value suffered by the pedestrian during the impact and improving the pedestrian protection performance of the vehicle.

[0048] The following describes the engine hood assembly 100 and the vehicle proposed in the embodiments of the present application with reference to the accompanying drawings.

[0049] As Figures 1-6 shown, the engine hood assembly 100 according to the first aspect embodiment of the present application includes: an engine hood inner panel 1, a mounting plate 2, and a mounting bracket 3.

[0050] Among them, the mounting plate 2 is fixedly connected to the inner panel 1 of the engine hood. The mounting plate 2 has a first mounting surface 21 and a second mounting surface 22. Along the first direction X, the first mounting surface 21 is spaced apart from the second mounting surface 22, and the second mounting surface 22 is closer to the inner panel 1 of the engine hood than the first mounting surface 21. Along the second direction Y, the first mounting surface 21 is disposed at the lower end of the second mounting surface 22. The first mounting surface 21 is connected to the second mounting surface 22 through a first connecting surface 23. And along the first direction X, the first mounting surface 21 protrudes from the front end of the inner panel 1 of the engine hood. The first direction X is perpendicular to the second direction Y. The mounting bracket 3 includes a first support portion 31 and a first mounting portion 32. Along the first direction X, the first mounting portion 32 is spaced apart from the second mounting surface 22 and is located on the side of the second mounting surface 22 close to the first mounting surface 21. The first support portion 31 is fixedly connected between the second mounting surface 22 and the first mounting portion 32. The first mounting surface 21 and the first mounting portion 32 are both used for mounting the front bumper skin. Among them, the first support portion 31 has a first collapsible portion 311 that can be collapsed and deformed along the first direction X.

[0051] Specifically, the first direction X is set as the front-rear direction of the vehicle, and the front direction of the vehicle is the front, and the rear direction is the rear. The second direction Y is set as the up-down direction of the vehicle, and the direction away from the ground is the upper, and the direction towards the ground is the lower.

[0052] Along the second direction Y, the inner panel 1 of the engine hood covers the upper part of the engine compartment. The inner panel 1 of the engine hood has a certain supporting function. The mounting plate 2 and the mounting bracket 3 of the engine hood assembly 100 are used for mounting the front bumper structure. In some embodiments of the present application, the mounting plate 2 and the mounting bracket 3 are used for mounting the front bumper skin. It can be understood that the mounting plate 2 and the mounting bracket 3 can also be used for mounting other structures, such as mounting the hood lock assembly structure, etc., which are not specifically limited here.

[0053] Please refer to Figures 1-3 As shown, along the first direction X, the first mounting surface 21 is spaced apart from the second mounting surface 22 and is located in front of the second mounting surface 22. Further, along the second direction Y, the first mounting surface 21 is disposed at the lower end of the second mounting surface 22, and the first mounting surface 21 is connected to the second mounting surface 22 through the first connecting surface 23. For the convenience of the cooperative installation of the mounting bracket 3 and the front bumper structure, the first mounting surface 21 and the second mounting surface 22 are configured as vertical surfaces, or the first mounting surface 21 and the second mounting surface 22 are configured as approximately vertical surfaces. The first connecting surface 23 can be configured as a horizontal connecting surface or can be configured as an approximately horizontal connecting surface.

[0054] With such a setting, the first mounting surface 21, the first connecting surface 23, and the second mounting surface 22 that are sequentially connected on the mounting plate 2 form a bent structure as a whole. This is beneficial to improving the strength of the mounting plate 2 in the vertical and horizontal directions of the vehicle. When structural components such as the front bumper skin are installed on the mounting plate 2, the mounting plate 2 can provide a good supporting effect, thus ensuring the overall strength of the engine hood assembly 100.

[0055] It should be noted that in this application, along the first direction X, the first mounting surface 21 of the mounting plate 2 protrudes from the front end of the inner panel 1 of the engine hood. The first mounting surface 21 is used to mount the front bumper skin. The front bumper skin usually corresponds to the position of the pedestrian's legs. Therefore, when the front bumper skin of the vehicle collides with a pedestrian, due to the relatively high structural strength of the mounting plate 2, it may cause greater harm to the pedestrian's legs during the collision, which is not conducive to pedestrian protection during the collision.

[0056] Based on this, the engine hood assembly 100 in this application is further provided with a mounting bracket 3. The mounting bracket 3 includes a first mounting portion 32 and a first supporting portion 31. Along the first direction X, the first mounting portion 32 is spaced apart from the second mounting surface 22, and the first mounting portion 32 is disposed in front of the second mounting surface 22. The first supporting portion 31 is fixedly connected between the second mounting surface 22 and the first mounting portion 32. It can be understood that the first supporting portion 31 can be vertically connected between the second mounting surface 22 and the first mounting portion 32, or can be connected between the second mounting surface 22 and the first mounting portion 32 approximately vertically, which is specifically set according to actual needs and will not be specifically limited here.

[0057] Furthermore, the first mounting portion 32 and the first mounting surface 21 of the mounting plate 2 cooperate to mount the front bumper skin together. For example, along the first direction X, the first mounting portion 32 can be flush with the first mounting surface 21 of the mounting plate 2, or the first mounting portion 32 can protrude from the first mounting surface 21.

[0058] When the front bumper skin of the vehicle collides with a pedestrian, the collision force will act on both the first mounting portion 32 and the first mounting surface 21 of the mounting plate 2 at the same time. Since the first supporting portion 31 is provided with a first collapsing portion 311 that can collapse and deform along the first direction X, when the front bumper structure of the vehicle collides with a pedestrian, the first supporting portion 31 can collapse and deform along the first direction X to absorb energy, thereby increasing the collapsing space of the front bumper structure, which is beneficial to reducing the injury value of the legs of the pedestrian during the impact and improving the pedestrian protection performance of the vehicle.

[0059] In some embodiments of this application, the first collapsing portion 311 can be configured as a collapsing hole or a collapsing groove, as long as the first collapsing portion 311 can collapse and deform in the first direction X.

[0060] In summary, according to the engine hood assembly 100 proposed in the first aspect embodiment of the present application, the first mounting surface 21 of the mounting plate 2 is spaced apart from the second mounting surface 22 along the first direction X, and along the second direction Y, the first mounting surface 21 is provided at the lower end of the second mounting surface 22. The first mounting surface 21 is connected to the second mounting surface 22 through the first connecting surface 23. In this way, the mounting plate 2 is integrally bent, which is beneficial to improving the strength of the mounting plate 2, and further ensures the overall strength of the engine hood assembly 100. At the same time, the first mounting portion 32 of the mounting bracket 3 is fixedly mounted on the first mounting surface 21 of the mounting plate 2 through the first supporting portion 31, and the front bumper skin is fixedly mounted on the vehicle body through the first mounting surface 21 and the first mounting portion 32. The first supporting portion 31 has a first collapsible portion 311 that can be collapsed and deformed along the first direction X. When the front bumper structure of the vehicle collides with a pedestrian, the first supporting portion 31 can be collapsed and deformed along the first direction X to absorb energy, thereby increasing the collapse space of the front bumper structure, which is beneficial to reducing the injury value suffered by the pedestrian during the impact and improving the pedestrian protection performance of the vehicle.

[0061] In some embodiments of the present application, such as Figure 3 and Figure 4 shown, there are multiple first supporting portions 31. Along the third direction Z, the multiple first supporting portions 31 are respectively arranged on both sides of the first mounting portion 32, where the third direction Z is perpendicular to both the first direction X and the second direction Y.

[0062] Specifically, each mounting bracket 3 can be provided with multiple first supporting portions 31, and each first supporting portion 31 is fixedly mounted between the second mounting surface 22 and the first mounting portion 32. For example, the number of the first supporting portions 31 can be 2, 3, 4, 5, or 6.

[0063] Furthermore, along the third direction Z, that is, along the left-right direction of the vehicle, the multiple first supporting portions 31 are respectively arranged on both sides of the first mounting portion 32. The multiple first supporting portions 31 can be symmetrically arranged on both sides of the first mounting portion 32, or can be asymmetrically arranged on both sides of the first mounting portion 32. As a specific example, as Figure 4 shown, the mounting bracket 3 is provided with four first supporting portions 31, and two first supporting portions 31 are symmetrically arranged on each of the left and right sides of the first mounting portion 32. Each first supporting portion 31 is fixedly mounted between the second mounting surface 22 and the first mounting portion 32 in an approximately perpendicular manner. In this way, the mounting bracket 3 is integrally in a shape of "J", which is beneficial to improving the supporting strength of the mounting bracket 3 in the up-down direction of the vehicle. When structural components such as the front bumper skin are fixedly mounted on the mounting bracket 3, the mounting bracket 3 can play a better supporting role and ensure the drooping and modal performance of the front bumper assembly.

[0064] It can be understood that at least one of the plurality of first support portions 31 is provided with a first collapsible portion 311 that can be collapsed and deformed along the first direction X. Preferably, each first support portion 31 is provided with a first collapsible portion 311 that can be collapsed and deformed along the first direction X.

[0065] In some embodiments of the present application, such as Figure 1 and Figure 3 shown, there are a plurality of mounting brackets 3, and the plurality of mounting brackets 3 are arranged at intervals in sequence along the third direction Z.

[0066] Specifically, along the third direction Z, that is, along the left - right direction of the vehicle, a plurality of mounting brackets 3 are installed on the second mounting surface 22 of the mounting plate 2, and the plurality of mounting brackets 3 are arranged at intervals in sequence. For example, the number of the mounting brackets 3 can be 2, 3, 4, 5, or 6.

[0067] As a specific example, as Figure 3 shown, two mounting brackets 3 are respectively provided on the left and right sides of the mounting plate 2. Each mounting bracket 3 is cooperatively installed with the first mounting surface 21 of the mounting plate 2 to install the front bumper skin. By providing a plurality of mounting brackets 3, it is beneficial to improve the support strength for structural components such as the front bumper skin, thereby further ensuring the drooping and modal performance of the front bumper assembly. At the same time, when the front bumper structure of the vehicle collides with a pedestrian, the plurality of mounting brackets 3 can collapse and absorb energy simultaneously, optimizing the force - transmission path of the collision force.

[0068] In some embodiments of the present application, such as Figure 3 shown, the mounting plate 2 further has a third mounting surface 24. Along the first direction X, the third mounting surface 24 is located on the side of the second mounting surface 22 away from the first mounting surface 21 and is spaced apart from the second mounting surface 22. Along the second direction Y, the third mounting surface 24 is provided at the upper end of the second mounting surface 22. The second mounting surface 22 is connected to the third mounting surface 24 through a second connection surface 25, and the third mounting surface 24 is used for installing the front bumper lamp.

[0069] Specifically, referring to Figure 1 and Figure 3 shown, along the first direction X, the third mounting surface 24 is spaced apart from the second mounting surface 22 and is located behind the second mounting surface 22. Along the second direction Y, the third mounting surface 24 is provided at the upper end of the second mounting surface 22, and the second mounting surface 22 is connected to the third mounting surface 24 through a second connection surface 25, and the third mounting surface 24 is used for installing the front bumper lamp.

[0070] In order to facilitate the installation of the front bumper lamp, the third mounting surface 24 can be configured as a vertical surface, or the third mounting surface 24 is configured as an approximately vertical surface, and the second connection surface 25 can be configured as a horizontal connection surface or an approximately horizontal connection surface.

[0071] With such a setting, the first mounting surface 21, the first connecting surface 23, the second mounting surface 22, the second connecting surface 25, and the third mounting surface 24 that are sequentially connected on the mounting plate 2 are integrally bent, ensuring the mounting strength and stiffness of the mounting plate 2, providing a better supporting effect, and further ensuring the overall strength of the engine hood assembly 100.

[0072] In some embodiments of the present application, such as Figure 1 , Figure 2 and Figure 5 shown, the inner panel 1 of the engine hood includes an inner panel body 11 and a buffer portion 12. Along the second direction Y, the buffer portion 12 is spaced apart from the inner panel body 11. The buffer portion 12 is used for fixedly connecting with the outer panel of the engine hood. The inner panel 1 of the engine hood further includes a second support portion 13. The second support portion 13 is fixedly connected between the buffer portion 12 and the inner panel body 11. Among them, the second support portion 13 has a second collapsible portion 131 that can be collapsibly deformed along the second direction Y.

[0073] Specifically, when the head of the vehicle collides with a pedestrian, the head of the pedestrian is likely to hit the upper area of the engine hood. Based on this, as Figure 2 and Figure 5 shown, the inner panel 1 of the engine hood is further provided with a buffer portion 12. The buffer portion 12 is located in the middle area of the inner panel 1 of the engine hood, and along the second direction Y, the buffer portion 12 is spaced apart from the inner panel body 11 and is arranged above the inner panel body 11.

[0074] Furthermore, the buffer portion 12 is used for fixedly connecting with the outer panel of the engine hood. The inner panel 1 of the engine hood further includes a second support portion 13. The second support portion 13 is fixedly connected between the buffer portion 12 and the inner panel body 11. The second support portion 13 has a second collapsible portion 131 that can be collapsibly deformed along the second direction Y. The second collapsible portion 131 can be configured as a collapsible hole or a collapsible groove, as long as the collapsible deformation of the second collapsible portion 131 in the second direction Y can be realized.

[0075] With such a setting, when the vehicle collides with a pedestrian and the head of the pedestrian hits the upper area of the engine hood, the collision force received by the outer panel of the engine hood acts on the buffer portion 12. The buffer portion 12 transmits the collision force to the second support portion 13. The second support portion 13 can be collapsibly deformed and absorb energy along the second direction Y under the action of the collision force, thereby increasing the collapsible space in the collision area of the pedestrian's head, being beneficial to reducing the injury value suffered by the head during the pedestrian's impact, and further improving the pedestrian protection performance of the vehicle.

[0076] In some embodiments of the present application, such as Figure 5As shown, the buffer portion 12 includes an annular frame 121 and a plurality of connecting rods 122, and along the first direction X, the front and rear ends of the connecting rods 122 are respectively fixedly connected to the annular frame 121, and along the third direction Z, the plurality of connecting rods 122 are arranged in sequence at intervals, wherein the third direction Z is perpendicular to the first direction X and the second direction Y, and there are a plurality of second support portions 13, and the plurality of second support portions 13 are arranged in sequence at intervals along the circumference of the annular frame 121, and each second support portion 13 is fixedly connected between the annular frame 121 and the inner plate body 11.

[0077] Specifically, the buffer portion 12 is composed of an annular frame 121 and a plurality of connecting rods 122. The plurality of connecting rods 122 are arranged in sequence along the third direction Z at intervals, and the front and rear ends of each connecting rod 122 are respectively fixedly connected to the annular frame 121. With such an arrangement, the buffer portion 12 is constructed as a hollow grille structure in the shape of a U.S. letter K. Such a design is conducive to reducing the strength of the buffer portion 12. When a pedestrian's head collides with the buffer portion 12 area of ​​the vehicle, the damage caused to the pedestrian by the buffer portion 12 can be further reduced.

[0078] Furthermore, the engine hood inner panel 1 has a plurality of second support portions 13, which are arranged in sequence and spaced apart along the circumference of the annular frame 121, and each second support portion 13 is fixedly connected between the annular frame 121 and the inner panel body 11. With such an arrangement, the plurality of second support portions 13 can better support the buffer portion 12, thereby ensuring the supporting performance of the engine hood inner panel 1 in the second direction Y.

[0079] It can be understood that at least one of the plurality of second support portions 13 is provided with a second shrinkage portion 131 that can shrink and deform along the second direction Y. Preferably, each second support portion 13 is provided with a second shrinkage portion 131 that can shrink and deform along the second direction Y.

[0080] In some embodiments of the present application, Figure 6 As shown, the connecting rod 122 has a glue-coated portion 1221 , the annular frame 121 has at least one through hole 1211 , and the extending direction of the glue-coated portion 1221 is staggered with the axis of the through hole 1211 .

[0081] Specifically, the connecting rod 122 has a glue portion 1221, and the glue portion 1221 is arranged on the upper end surface of the connecting rod 122, wherein the extension direction of the glue portion 1221 is consistent with the extension direction of the connecting rod 122. In the present application, the annular frame 121 has at least one through hole 1211, that is, the annular frame 121 can be provided with one through hole 1211, or a plurality of through holes 1211 can be provided. If the annular frame 121 is provided with a plurality of through holes 1211, the plurality of through holes 1211 can be arranged in sequence along the circumference of the annular frame 121. In order to meet the dent resistance of the engine hood inner panel 1, the extension direction of the glue portion 1221 is staggered from the axis of the through hole 1211. At the same time, this structural form of staggered through holes 1211 also makes the collision force better dispersed during the transmission process, which is beneficial to the collapse and deformation of the buffer portion 12 during the pedestrian head impact, increases the space for collapse and deformation, reduces the injury value during the pedestrian head impact, and further improves the pedestrian protection performance of the vehicle.

[0082] In some embodiments of the present application, Figure 1 As shown, it also includes: a reinforcing plate assembly 4, which is fixedly installed on the upper side of the inner plate body 11 along the second direction Y, and the reinforcing plate assembly 4 is arranged around the inner plate body 11.

[0083] It should be noted that if Figure 5 As shown, the inner panel body 11 area has basically no effect on pedestrian leg protection impact, and also has little effect on pedestrian head protection impact. At the same time, in order to meet the functions of the engine hood inner panel 1 such as storage and seating, it is necessary to improve the strength of the inner panel body 11 area.

[0084] In the present application, in order to improve the strength of the inner panel body 11 area, the engine hood assembly 100 is also provided with a reinforcing plate assembly 4, wherein the reinforcing plate assembly 4 is fixedly mounted on the upper side of the inner panel body 11, and the reinforcing plate assembly 4 is arranged around the inner panel body 11, and the reinforcing plate assembly 4 as a whole can be constructed as a ring U-shaped structure. For example, the reinforcing plate assembly 4 surrounds the buffer portion 12 along the circumference of the inner panel body 11 and forms a 3 / 4 ring U-shaped structure. Of course, the reinforcing plate assembly 4 can also be arranged as other ring U-shaped structures, which are arranged according to actual conditions and are not specifically limited here. In this way, the structural strength of the inner panel body 11 can be improved by arranging the reinforcing plate assembly 4 without having a significant impact on pedestrian protection, which is conducive to improving the modal, strength, dent resistance and other properties of the engine hood inner panel 1.

Along the first direction X, the second strut reinforcement plate 44 is closer to the front end of the inner engine hood panel 1 than the second hinge reinforcement plate 42. The reinforcement plate assembly 4 includes a front-end reinforcement plate 45. Along the first direction X, the front-end reinforcement plate 45 is closer to the front end of the inner engine hood panel 1 than the first strut reinforcement plate 43 and the second strut reinforcement plate 44. The first hinge reinforcement plate 41, the first strut reinforcement plate 43, the front-end reinforcement plate 45, the second strut reinforcement plate 44, and the second hinge reinforcement plate 42 are sequentially connected to form the reinforcement plate assembly 4.

[0086] Specifically, along the first direction X, the first hinge reinforcement plate 41 and the second hinge reinforcement plate 42 are arranged at the position close to the rear end of the inner panel body 11, and along the third direction Z, the first hinge reinforcement plate 41 and the second hinge reinforcement plate 42 are respectively arranged on both sides of the inner panel body 11. Along the first direction X, the first strut reinforcement plate 43 and the second strut reinforcement plate 44 are arranged at the middle position of the inner panel body 11, and along the third direction Z, the first hinge reinforcement plate 41 and the second hinge reinforcement plate 42 are respectively arranged on both sides of the inner panel body 11. Along the first direction X, the front-end reinforcement plate 45 is arranged at the position close to the front end of the inner panel body 11, and the front-end reinforcement plate 45 extends integrally along the third direction Z. Further, the first hinge reinforcement plate 41, the first strut reinforcement plate 43, the front-end reinforcement plate 45, the second strut reinforcement plate 44, and the second hinge reinforcement plate 42 are sequentially connected to form the reinforcement plate assembly 4 in a ring U-shaped structure, where the ring U-shaped structure surrounds the buffer portion 12. Thus, it is beneficial to improve the structural strength of the inner panel body 11.

[0087] It should be noted that the first hinge reinforcement plate 41, the first strut reinforcement plate 43, the front-end reinforcement plate 45, the second strut reinforcement plate 44, and the second hinge reinforcement plate 42 are all provided with serrated structures. The first hinge reinforcement plate 41, the first strut reinforcement plate 43, the front-end reinforcement plate 45, the second strut reinforcement plate 44, and the second hinge reinforcement plate 42 are fixedly installed on the inner panel body 11 through the serrated structures. It can be understood that the serrated structures are configured as multiple spaced mounting convex plates that cooperate with the inner panel body 11, which will not be elaborated here.

[0088] In a second aspect, an embodiment of the present application provides a vehicle, including the engine hood assembly 100 in the first aspect embodiment.
