[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0042] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0045] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0046] It should be noted that with the rapid development of the automotive industry, more and more car manufacturers are integrating the front bumper structure onto the front of the hood. This installation method requires the hood to have strong structural strength. However, excessively strong hood structure 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 hood has become an urgent technical problem to be solved.

[0047] Based on this, this 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 located 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 has a bent structure, which helps to improve the strength of the mounting plate 2 and thus ensures the overall strength of the engine hood assembly 100. At the same time, the first mounting part 32 of the mounting bracket 3 is fixedly mounted on the first mounting surface 21 of the mounting plate 2 through the first support part 31. The front bumper skin is fixedly mounted on the vehicle body through the first mounting surface 21 and the first mounting part 32. The first support part 31 has a first collapsible part 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 support part 31 can collapse and deform along the first direction X to absorb energy, thereby increasing the collapse space of the front bumper structure, which helps to reduce the injury value of the pedestrian during the impact and improves the pedestrian protection performance of the vehicle.

[0048] The engine hood assembly 100 and the vehicle according to embodiments of this application are described below with reference to the accompanying drawings.

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

[0050] The mounting plate 2 is fixedly connected to the inner panel of the engine hood 1. 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 and the second mounting surface 22 are spaced apart, and the second mounting surface 22 is closer to the inner panel of the engine hood 1 than the first mounting surface 21. Along the second direction Y, the first mounting surface 21 is located 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 inner panel of the engine hood 1. At the front end, the first direction X is perpendicular to the second direction Y. The mounting bracket 3 includes a first support part 31 and a first mounting part 32. Along the first direction X, the first mounting part 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 part 31 is fixedly connected between the second mounting surface 22 and the first mounting part 32. The first mounting surface 21 and the first mounting part 32 are both used to install the front bumper skin. The first support part 31 has a first collapsible part 311 that can collapse and deform along the first direction X.

[0051] Specifically, the first direction X is defined as the front-to-back direction of the vehicle, with the front of the vehicle being forward and the rear being backward. The second direction Y is defined as the up-to-down direction of the vehicle, with the direction away from the ground being up and the direction towards the ground being down.

[0052] Along the second direction Y, the inner panel 1 of the engine hood covers the engine compartment. The inner panel 1 of the engine hood has a certain supporting function. The mounting plate 2 and mounting bracket 3 of the engine hood assembly 100 are used to install the front bumper structure. In some embodiments of this application, the mounting plate 2 and mounting bracket 3 are used to install the front bumper skin. It is understood that the mounting plate 2 and mounting bracket 3 can also be used to install other structures, such as the hood lock assembly structure, etc. No specific limitation is made 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 located 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. To facilitate the installation of the mounting bracket 3 and the front bumper structure, the first mounting surface 21 and the second mounting surface 22 are constructed as vertical surfaces, or as approximately vertical surfaces. The first connecting surface 23 can be constructed as a horizontal connecting surface or as approximately horizontal connecting surface.

[0054] With this configuration, the first mounting surface 21, the first connecting surface 23, and the second mounting surface 22 connected sequentially on the mounting plate 2 form a bent structure. This helps to improve 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 better support, thereby 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 a pedestrian's legs. Therefore, when the front bumper skin of the vehicle collides with a pedestrian, due to the high structural strength of the mounting plate 2, it may cause significant damage 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 also provided with a mounting bracket 3. The mounting bracket 3 includes a first mounting part 32 and a first support part 31. Along the first direction X, the first mounting part 32 is spaced apart from the second mounting surface 22, and the first mounting part 32 is located in front of the second mounting surface 22. The first support part 31 is fixedly connected between the second mounting surface 22 and the first mounting part 32. It can be understood that the first support part 31 can be vertically connected between the second mounting surface 22 and the first mounting part 32, or it can be approximately vertically connected between the second mounting surface 22 and the first mounting part 32. The specific setting depends on the actual needs, and no specific limitation is made here.

[0057] Furthermore, the first mounting part 32 and the first mounting surface 21 of the mounting plate 2 cooperate to install the front bumper skin. For example, along the first direction X, the first mounting part 32 can be flush with the first mounting surface 21 of the mounting plate 2, or the first mounting part 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 simultaneously on the first mounting part 32 and the first mounting surface 21 of the mounting plate 2. Since the first support part 31 is provided with a first crumple part 311 that can crumple and deform along the first direction X, when the front bumper structure of the vehicle collides with a pedestrian, the first support part 31 can crumple and deform along the first direction X to absorb energy, thereby increasing the crumple space of the front bumper structure, which helps to reduce the injury value to the pedestrian's legs during the impact and improves the pedestrian protection performance of the vehicle.

[0059] In some embodiments of this application, the first collapse portion 311 can be constructed as a collapse hole or a collapse groove, which can realize the collapse deformation of the first collapse portion 311 in the first direction X.

[0060] In summary, according to the engine hood assembly 100 proposed in the first aspect embodiment of this 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 located 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 has a bent structure as a whole, which is beneficial to improving the strength of the mounting plate 2, thereby ensuring the overall strength of the engine hood assembly 100. At the same time, the first mounting part 32 of the mounting bracket 3 is fixedly mounted on the first mounting surface 21 of the mounting plate 2 through the first support part 31. The front bumper skin is fixedly mounted on the vehicle body through the first mounting surface 21 and the first mounting part 32. The first support part 31 has a first collapsible part 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 support part 31 can collapse and deform 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 of the pedestrian during the impact and improving the pedestrian protection performance of the vehicle.

[0061] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, there are multiple first support parts 31. Along the third direction Z, the multiple first support parts 31 are respectively arranged on both sides of the first mounting part 32, wherein the third direction Z is perpendicular to both the first direction X and the second direction Y.

[0062] Specifically, each mounting bracket 3 may be provided with multiple first support parts 31, and each first support part 31 is fixedly installed between the second mounting surface 22 and the first mounting part 32. For example, the number of first support parts 31 may be 2, 3, 4, 5, or 6.

[0063] Furthermore, along the third direction Z, i.e., along the left-right direction of the vehicle, a plurality of first support portions 31 are respectively disposed on both sides of the first mounting portion 32. The plurality of first support portions 31 can be symmetrically disposed on both sides of the first mounting portion 32, or asymmetrically disposed on both sides of the first mounting portion 32. As a specific example, for instance... Figure 4 As shown, the mounting bracket 3 is provided with four first support parts 31. Two first support parts 31 are symmetrically provided on the left and right sides of the first mounting part 32. Each first support part 31 is fixedly installed approximately vertically between the second mounting surface 22 and the first mounting part 32. Thus, the mounting bracket 3 is shaped like a "Z". This helps to improve the support strength of the mounting bracket 3 in the vertical direction of the vehicle. When structural components such as the front bumper skin are fixedly installed on the mounting bracket 3, the mounting bracket 3 can play a better supporting role, ensuring the sag and modal performance of the front bumper assembly.

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

[0065] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, there are multiple mounting brackets 3, which are arranged at intervals along the third direction Z.

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

[0067] As a concrete example, such as Figure 3 As shown, two mounting brackets 3 are respectively provided on the left and right sides of the mounting plate 2. Each mounting bracket 3 is used to mount the front bumper skin on the first mounting surface 21 of the mounting plate 2. By setting multiple mounting brackets 3, the support strength for structural components such as the front bumper skin is improved, thereby further ensuring the sag and modal performance of the front bumper assembly. At the same time, when the front bumper structure of the vehicle collides with a pedestrian, multiple mounting brackets 3 can simultaneously crumple and absorb energy, optimizing the force transmission path of the collision.

[0068] In some embodiments of this application, such as Figure 3 As shown, the mounting plate 2 also 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 located at the upper end of the second mounting surface 22. The second mounting surface 22 is connected to the third mounting surface 24 through the second connecting surface 25. The third mounting surface 24 is used to mount the front protection lamp.

[0069] Specifically, refer to Figure 1 and Figure 3 As shown, along the first direction X, the third mounting surface 24 is spaced apart from the second mounting surface 22 and located behind the second mounting surface 22. Along the second direction Y, the third mounting surface 24 is located 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 the second connecting surface 25. The third mounting surface 24 is used to install the front protection lamp.

[0070] To facilitate the installation of the front protection light fixture, the third mounting surface 24 can be constructed as a vertical surface, or the third mounting surface 24 can be constructed as an approximately vertical surface, and the second connecting surface 25 can be constructed as a horizontal connecting surface, or it can be constructed as an approximately horizontal connecting surface.

[0071] With this configuration, 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 connected sequentially on the mounting plate 2 form a bent structure, which ensures the installation strength and rigidity of the mounting plate 2, provides better support, and further ensures the overall strength of the engine hood assembly 100.

[0072] In some embodiments of this application, such as Figure 1 , Figure 2 and Figure 5 As 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 to be fixedly connected to the outer panel of the engine hood. The inner panel 1 of the engine hood also includes a second support portion 13, which 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 collapse and deform along the second direction Y.

[0073] Specifically, when the front of a vehicle collides with a pedestrian, the pedestrian's head is more likely to hit the area above the hood. Based on this, if... Figure 2 and Figure 5 As shown, the inner panel 1 of the engine hood is also provided with a buffer part 12. The buffer part 12 is located in the middle area of ​​the inner panel 1 of the engine hood and is spaced apart from the inner panel body 11 along the second direction Y and is provided above the inner panel body 11.

[0074] Furthermore, the buffer portion 12 is used to be fixedly connected to the outer panel of the engine hood, and the inner panel of the engine hood 1 also 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 collapse and deform along the second direction Y. The second collapsible portion 131 can be constructed as a collapsible hole or a collapsible groove, as long as the second collapsible portion 131 can collapse and deform in the second direction Y.

[0075] With this configuration, when a vehicle collides with a pedestrian and the pedestrian's head hits the area above the hood, the impact force on the outer panel of the hood acts on the buffer part 12. The buffer part 12 transmits the impact force to the second support part 13. Under the action of the impact force, the second support part 13 can collapse and deform along the second direction Y to absorb energy, thereby increasing the collapse space in the pedestrian's head impact area. This helps to reduce the injury value to the pedestrian's head during the impact and further improves the vehicle's pedestrian protection performance.

[0076] In some embodiments of this application, such as Figure 5As shown, the buffer part 12 includes an annular frame 121 and multiple connecting rods 122. Along the first direction X, the front and rear ends of the connecting rods 122 are fixedly connected to the annular frame 121, and along the third direction Z, the multiple connecting rods 122 are arranged at intervals in sequence. The third direction Z is perpendicular to both the first direction X and the second direction Y. There are multiple second support parts 13. The multiple second support parts 13 are arranged at intervals in sequence along the circumference of the annular frame 121, and each second support part 13 is fixedly connected between the annular frame 121 and the inner plate body 11.

[0077] Specifically, the buffer section 12 consists of an annular frame 121 and multiple connecting rods 122. The multiple connecting rods 122 are arranged sequentially at intervals along the third direction Z, and the front and rear ends of each connecting rod 122 are fixedly connected to the annular frame 121 respectively. With this arrangement, the buffer section 12 is constructed as a grid-like hollow structure. This design helps to reduce the strength of the buffer section 12. When a pedestrian's head collides with the buffer section 12 area of ​​the vehicle, it can further reduce the injury caused to the pedestrian by the buffer section 12.

[0078] Furthermore, there are multiple second support portions 13 of the inner panel 1 of the engine hood. The multiple second support portions 13 are arranged sequentially 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 panel body 11. With this arrangement, the multiple second support portions 13 can better support the buffer portion 12 and ensure the support performance of the inner panel 1 of the engine hood in the second direction Y.

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

[0080] In some embodiments of this application, such as Figure 6 As shown, the connecting rod 122 has a glue-applying part 1221, the annular frame 121 has at least one through hole 1211, and the extending direction of the glue-applying part 1221 is offset from the axis of the through hole 1211.

[0081] Specifically, the connecting rod 122 has a glue-applying part 1221, which is disposed on the upper end face of the connecting rod 122. The extending direction of the glue-applying part 1221 is consistent with the extending direction of the connecting rod 122. In this 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 multiple through holes 1211. If the annular frame 121 is provided with multiple through holes 1211, the multiple through holes 1211 can be arranged sequentially at intervals along the circumference of the annular frame 121. In order to meet the anti-dent performance of the inner panel 1 of the engine hood, the extending direction of the glue-applying part 1221 is offset from the axis of the through hole 1211. At the same time, this structure of offset through holes 1211 also makes the collision force better dispersed during the transmission process, which is conducive to the collapse deformation of the buffer part 12 during the pedestrian head impact, increases the space for collapse 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 this application, such as 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, as Figure 5 As shown, the inner panel body 11 area has virtually no impact on the pedestrian's leg impact and also has a relatively small impact on the pedestrian's head 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 increase the strength of the inner panel body 11 area.

[0084] In this application, to improve the strength of the inner panel body 11 area, the engine hood assembly 100 also includes a reinforcing plate assembly 4. The reinforcing plate assembly 4 is fixedly installed on the upper side of the inner panel body 11 and surrounds the inner panel body 11. The reinforcing plate assembly 4 can be constructed as a U-shaped ring structure. For example, the reinforcing plate assembly 4 surrounds the buffer portion 12 circumferentially around the inner panel body 11, forming a 3 / 4 U-shaped ring structure. Of course, the reinforcing plate assembly 4 can also be configured as other U-shaped ring structures, depending on the actual situation; no specific limitations are made here. Thus, without significantly affecting pedestrian protection, the structural strength of the inner panel body 11 can be improved by providing the reinforcing plate assembly 4, which is beneficial for improving the modal characteristics, strength, and dent resistance of the engine hood inner panel 1.

[0085] In some embodiments of this application, such as Figure 1As shown, the reinforcing plate assembly 4 includes a first hinge reinforcing plate 41 and a second hinge reinforcing plate 42. Along the third direction Z, the first hinge reinforcing plate 41 and the second hinge reinforcing plate 42 are respectively disposed on both sides of the inner plate body 11. The third direction Z is perpendicular to both the first direction X and the second direction Y. The reinforcing plate assembly 4 also includes a first strut reinforcing plate 43 and a second strut reinforcing plate 44. Along the third direction Z, the first strut reinforcing plate 43 and the second strut reinforcing plate 44 are respectively disposed on both sides of the inner plate body 11. Along the first direction X, the first strut reinforcing plate 43 is positioned relative to the first hinge reinforcing plate 42. The reinforcing plate 41 is closer to the front end of the inner panel 1 of the engine hood along the first direction X. The second strut reinforcing plate 44 is closer to the front end of the inner panel 1 of the engine hood than the second hinge reinforcing plate 42. The reinforcing plate assembly 4 includes a front reinforcing plate 45. Along the first direction X, the front reinforcing plate 45 is closer to the front end of the inner panel 1 of the engine hood than the first strut reinforcing plate 43 and the second strut reinforcing plate 44. The first hinge reinforcing plate 41, the first strut reinforcing plate 43, the front reinforcing plate 45, the second strut reinforcing plate 44, and the second hinge reinforcing plate 42 are connected in sequence to form the reinforcing plate assembly 4.

[0086] Specifically, along the first direction X, the first hinge reinforcement plate 41 and the second hinge reinforcement plate 42 are disposed near the rear end of the inner plate body 11, and along the third direction Z, the first hinge reinforcement plate 41 and the second hinge reinforcement plate 42 are respectively disposed on both sides of the inner plate body 11. Along the first direction X, the first strut reinforcement plate 43 and the second strut reinforcement plate 44 are disposed in the middle of the inner plate body 11, and along the third direction Z, the first hinge reinforcement plate 41 and the second hinge reinforcement plate 42 are respectively disposed on both sides of the inner plate body 11. Along the first direction X, the front reinforcement plate 45 is disposed near the front end of the inner plate body 11, and the front reinforcement plate 45 extends entirely along the third direction Z. Furthermore, the first hinge reinforcement plate 41, the first strut reinforcement plate 43, the front reinforcement plate 45, the second strut reinforcement plate 44, and the second hinge reinforcement plate 42 are sequentially connected to form a U-shaped ring reinforcement plate assembly 4, wherein the U-shaped ring structure is disposed around the buffer part 12, which is beneficial to improving the structural strength of the inner plate 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 a serrated structure. 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 plate body 11 through the serrated structure. It can be understood that the serrated structure is constructed as multiple spaced mounting protrusions that mate with the inner plate body 11, which will not be described in detail here.

[0088] Secondly, embodiments of this application provide a vehicle including the engine hood assembly 100 of the first aspect embodiment.

[0089] According to the vehicle proposed in the second aspect embodiment of this application, by providing the aforementioned engine hood assembly 100, in which the first mounting surface 21 of the mounting plate 2 in the engine hood assembly 100 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 located 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 a first connecting surface 23, thus making the mounting plate 2 have a bent structure as a whole, which is beneficial to improving the strength of the mounting plate 2, thereby ensuring the overall strength of the engine hood assembly 100. Meanwhile, The first mounting part 32 of the mounting bracket 3 is fixedly mounted on the first mounting surface 21 of the mounting plate 2 via the first support part 31. The front bumper skin is fixedly mounted on the vehicle body via the first mounting surface 21 and the first mounting part 32. The first support part 31 has a first crumple portion 311 that can crumple and deform along the first direction X. When the front bumper structure of the vehicle collides with a pedestrian, the first support part 31 can crumple and deform along the first direction X to absorb energy, thereby increasing the crumple space of the front bumper structure, which helps to reduce the injury value of the pedestrian during the impact and improves the pedestrian protection performance of the vehicle.
