Description

Technical Field

[0002] With the rapid development of the automobile industry, the number of vehicles has increased, and vehicle performance has improved. Higher requirements have been placed on pedestrian protection. The hood is an important assembly of automobile covering parts, and it is also an important area of ​​concern for pedestrian protection. The hood lock hook and hood hinge are structures for opening and closing the hood. The lock hook reinforcement plate and hinge reinforcement plate are also necessary parts for the safe and normal opening and closing of the lock hook. The hood support plate is a structure that supports the hood. The lock hook reinforcement plate, hinge reinforcement plate and hood support plate all need to have a certain structural strength to meet the use requirements, but too high a structural strength will cause excessive damage to pedestrians in pedestrian protection tests, resulting in insufficient protection for pedestrians and difficulty in achieving a balance in comprehensive performance.

[0063] It should be noted that the engine hood is an important assembly of automobile covering parts, and the design requirements of the engine hood are: good structural strength and good pedestrian protection. However, the structural strength of the engine hood and the pedestrian protection capability are often negatively correlated. When the structural strength of the engine hood is high, the damage to pedestrians is bound to increase. When the pedestrian protection capability of the engine hood is high, the structural strength of the engine hood is also reduced accordingly. Therefore, the structural strength requirements of the engine hood and the pedestrian protection capability requirements are contradictory. When designing the engine hood, it is necessary to make a trade-off between structural strength and pedestrian protection capability.

[0064] Reference Figures 1 to 6As shown, the first embodiment of the utility model proposes a hood reinforcement structure, including: a first reinforcement plate 100, a second reinforcement plate 200 and a support assembly, the first reinforcement plate 100 and the second reinforcement plate 200 are both used to connect the hood lock structure of the hood to strengthen the structural strength of the hood lock structure, along the left and right directions, the first reinforcement plate 100 and the second reinforcement plate 200 are arranged at intervals; the support assembly is arranged between the first reinforcement plate 100 and the second reinforcement plate 200, the support assembly includes a first support plate 300 and a second support plate 400, along the front and rear directions, the first support plate 300 is limited to the first reinforcement plate 100, and / or the second support plate 400 is limited to the second reinforcement plate 200; along the up and down directions, there is a first deformation position 500 suitable for deformation of the hood between the first support plate 300 and the second support plate 400; the support The component is configured as follows: when the front side of the hood is subjected to an external impact in the front-to-back direction, the first support plate 300 is limited to the first reinforcement plate 100, and / or the second support plate 400 is limited to the second reinforcement plate 200; the support component is also configured as follows: when the top surface of the hood is subjected to an external impact in the up-down direction, the hood is suitable for deforming at the first deformation position 500, so that the hood reinforcement structure of this embodiment can increase the structural strength of the hood in the front-to-back direction by limiting the first support plate 300 and the first reinforcement plate 100, and the second support plate 400 and the second reinforcement plate 200 in the front-to-back direction; through the first deformation position 500 between the first support plate 300 and the second support plate 400, the hood is more easily deformed in the up-down direction to form a buffer, thereby improving the pedestrian protection capability of the hood.

[0065] It should be noted that the engine hood includes a hood inner panel and a hood outer panel 600, a support space is provided between the hood inner panel and the hood outer panel 600, the support assembly is arranged in the support space, welded to the hood inner panel, and bonded to the hood outer panel 600; the first reinforcement plate 100 and the second reinforcement plate 200 are welded to the hood inner panel, and the hood lock structure is welded to the first reinforcement plate 100 and the second reinforcement plate 200.

[0066] In this embodiment, refer to Figure 3 As shown, the first reinforcing plate 100 and the second reinforcing plate 200 are symmetrically distributed about the central axis of the engine hood along the front-to-back direction, making the layout more beautiful and the force distribution more uniform. The first reinforcing plate 100 and the second reinforcing plate 200 are both welded to the inner plate of the engine hood, and the reliability of the connection is stronger. Among them, the first reinforcing plate 100 and the second reinforcing plate 200 can also be asymmetrically distributed about the central axis, for example, along the left-right direction, the first reinforcing plate 100 and the second reinforcing plate 200 are aligned, but the distance from the first reinforcing plate 100 to the central axis is greater or less than the distance from the second reinforcing plate 200 to the central axis; or, along the left-right direction, the first reinforcing plate 100 and the second reinforcing plate 200 are not aligned, but are staggered.

[0067] Specifically, refer to Figure 1 and Figure 2 As shown, the first reinforcing plate 100 is irregular in shape, and the contour shape of the first reinforcing plate 100 is a combination of multiple arc segments and multiple straight line segments. The shape of the first reinforcing plate 100 is obtained through simulation testing, so that the force at each connection position of the cover lock structure is basically uniform, thereby improving the connection strength of the cover lock structure. The structure of the second reinforcing plate 200 is the same as that of the first reinforcing plate 100, and is symmetrical about the central axis.

[0068] Reference Figure 3 As shown, the support assembly includes a first support plate 300 and a second support plate 400, the first support plate 300 and the second support plate 400 are symmetrically distributed about the central axis of the engine hood along the front-rear direction, the first support plate 300 and the second support plate 400 are both welded to the hood inner plate, and bonded to the hood outer plate 600. The first support plate 300 and the second support plate 400 may also be asymmetrically distributed.

[0069] Specifically, refer to Figure 1 and Figure 2 As shown, the first support plate 300 includes a first plate portion 310 and a plurality of first support legs 320 connected to the first plate portion 310. In the up-down direction, the first support legs 320 are inclined toward the outside of the first plate portion 310. One end of the first support legs 320 away from the first plate portion 310 is welded to the hood inner plate. The plurality of first support legs 320 are sequentially spaced around the edge of the first support plate 300 to support the first plate portion 310 through the first support legs 320. When the top surface of the hood is subjected to a large external impact in the up-down direction, the first support legs 320 can collapse and absorb energy in the up-down direction to reduce the impact on the hood inner plate and the hood below the hood inner plate. The first plate portion 310 is in an arc-shaped plate shape, and the center of the first plate portion 310 is located at the rear of the vehicle in the front-rear direction. The front side of the hood is an arc line, and the first plate portion 310 is shaped similar to the arc line on the front side of the hood to make the force distribution of the hood more uniform; a plurality of first glue grooves are provided on the side of the first plate portion 310 away from the hood inner panel to be bonded to the hood outer panel 600, wherein the first glue grooves include a first sub-glue groove 311 along the left-right direction and a second sub-glue groove 312 along the front-back direction to increase the bonding strength between the first plate portion 310 and the hood inner panel; the first plate portion 310 is also provided with a plurality of first weight-reducing holes 313 distributed in sequence along the left-right direction to reduce the overall weight of the first support plate 300. At the same time, when the front side of the hood is subjected to a large impact along the front-back direction, the first support plate 300 can collapse and absorb energy along the front-back direction through the side walls forming the first weight-reducing holes 313.

[0070] The second support plate 400 also has a second plate portion and a plurality of second support feet connected to the second plate portion, the second support feet are arranged in the up-down direction or inclined in the up-down direction, one end of the second support foot away from the second plate portion is welded to the hood inner plate, and the plurality of second support feet are distributed in sequence around the edge of the second support plate 400, and the function of the second support foot is the same as that of the first support foot 320; the second plate portion is also in the shape of an arc plate, the center of the second plate portion is located at the rear of the vehicle along the front-to-back direction, and the second plate portion is also shaped like the arc line on the front side of the engine hood; a plurality of second glue grooves are provided on a side of the second plate portion away from the hood inner plate to be bonded to the hood outer plate 600, wherein the second glue grooves include a third sub-glue groove along the left-right direction and a fourth sub-glue groove along the front-to-back direction to increase the bonding strength between the second plate portion and the hood inner plate; the second plate portion is also provided with a plurality of second weight-reducing holes distributed in sequence along the left-to-right direction, and the function of the second weight-reducing holes is the same as that of the first weight-reducing holes 313, which will not be repeated here.

[0071] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, along the front-to-back direction, the first support plate 300 is limited to the first reinforcement plate 100, and the first reinforcement plate 100 is connected to the locking structure of the vehicle body through the cover lock structure, that is, the first reinforcement plate 100 is fixed to the vehicle body through the cover lock structure. When the first support plate 300 is subjected to external impact along the front-to-back direction and has a deformation tendency along the front-to-back direction, the first reinforcement plate 100 will limit and support the first support plate 300 along the front-to-back direction, thereby improving the resistance of the engine hood to deformation. Similarly, along the front-to-back direction, when the second support plate 400 is limited to the second reinforcement plate 200, it also has the same effect as the first support plate 300 being limited to the first reinforcement plate 100, which will not be repeated here.

[0072] For ease of understanding, combined with the specific scenario when the front end of the vehicle collides, taking the first support plate 300 being limited to the first reinforcement plate 100 and the second support plate 400 being limited to the second reinforcement plate 200 as an example, an exemplary explanation is given as follows: when the front end of the vehicle collides, the front side of the hood is impacted along the front-to-back direction, and the first reinforcement plate 100 and the second reinforcement plate 200 are both connected to the vehicle body through a hood lock structure. Along the front-to-back direction, the first support plate 300 is limited to the first reinforcement plate 100, and the first support plate 300 transmits the impact to the vehicle body through the first reinforcement plate 100 and the hood lock structure; the second support plate 400 is limited to the second reinforcement plate 200, and the second support plate 400 transmits the impact to the vehicle body through the second reinforcement plate 200 and the hood lock structure, so that the ability of the hood to resist deformation along the front-to-back direction is enhanced, thereby increasing the structural strength of the hood along the front-to-back direction.

[0073] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, along the up and down directions, there is a first deformation position 500 between the first support plate 300 and the second support plate 400. When the hood outer panel 600 is impacted along the up and down directions, the hood outer panel 600 is more likely to deform along the up and down directions through the first deformation position 500 to form a buffer, thereby improving the buffering effect of the hood outer panel 600, avoiding rigid collision, and thereby reducing the damage to the pedestrian's head.

[0074] For ease of understanding, in combination with the specific scenario of the vehicle pedestrian protection test, an exemplary explanation is given as follows: in the vehicle pedestrian protection test, the legs of the pedestrian are hit by the front end of the vehicle, causing the pedestrian to fall toward the hood outer panel 600 of the hood, and the pedestrian's head will collide with the top surface of the hood outer panel 600. When the pedestrian's head collides with the top surface of the hood outer panel 600 and the hood outer panel 600 is subjected to a downward impact force, the hood outer panel 600 is more likely to deform downward through the first deformation position 500 to form a buffer, thereby reducing the damage to the pedestrian and improving the hood's ability to protect pedestrians.

[0075] It should be noted that the hood outer panel 600 has a certain curvature, and the angles at which pedestrians hit the hood outer panel 600 are various, resulting in the direction of the pedestrian impact force not being completely in the up-down direction, but tilted downward, so that the force direction of the hood outer panel 600 is tilted downward, but the force direction of the hood outer panel 600 has a component in the up-down direction, and the first support plate 300 and the second support plate 400 can buffer the component in the up-down direction through the first deformation position 500. In addition, when the hood outer panel 600 is deformed, it can be elastic deformation or plastic deformation.

[0076] Reference Figure 1 As shown, in some specific embodiments of the present invention, the first support plate 300 and the second support plate 400 are spaced apart in the left-right direction, and / or, the first support plate 300 and the second support plate 400 are spaced apart in the front-back direction.

[0077] It is worth understanding that the first support plate 300 and the second support plate 400 are spaced apart so that the spacing area between the first support plate 300 and the second support plate 400 forms a first deformation position 500. When a pedestrian collides with the hood outer panel 600 in the up and down directions, the hood outer panel 600 is more likely to deform through the first deformation position 500. The hood outer panel 600 can deform to a greater extent in the up and down directions, thereby improving the cushioning effect on pedestrians, especially improving the cushioning effect on pedestrians' heads, reducing injuries to pedestrians' heads, and improving the pedestrian protection capability of the hood.

[0078] As some other embodiments, the first support plate 300 can also abut against the second support plate 400 in the left-right direction, and the abutting position, namely the first deformation position 500, can also make the hood outer panel 600 more easily deformed at the first deformation position 500; or, the first support plate 300 is connected to the second support plate 400, but the connection position between the first support plate 300 and the second support plate 400 is weakened to reduce the structural strength of the connection position, thereby forming the first deformation position 500 where the hood outer panel 600 is easily deformed, for example, the first support plate 300 and the second support plate 400 are spot welded, and the connection position between the first support plate 300 and the second support plate 400 is thinned.

[0079] Reference Figure 4 , Figure 5 and Figure 6 As shown, in other embodiments of the present invention, the first support plate 300 can abut against the second support plate 400 along the front-to-back direction; the support assembly is also configured as follows: when the front side of the engine hood is subjected to external impact, the first support plate 300 and the second support plate 400 abut against each other along the front-to-back direction.

[0080] It is worth understanding that when the support assembly is impacted in the front-to-back direction, the first support plate 300 and the second support abut against each other and jointly resist the impact in the front-to-back direction, thereby improving the structural strength between the first support plate 300 and the second support plate 400 in the front-to-back direction, making the structural strength of the engine hood in the front-to-back direction higher.

[0081] It should be noted that in the pedestrian protection test of the vehicle, the legs of the pedestrian are hit by the front end of the vehicle. At this time, it is mainly the bumper at the front end of the vehicle that contacts the pedestrian and provides a buffer to reduce the damage to the pedestrian; the hood does not directly contact the legs of the pedestrian, and the hood and the body play a supporting role together. Therefore, when the structural strength of the hood along the front-to-back direction is strengthened, it will not cause a sharp increase in the damage value of the vehicle to the legs of the pedestrian. In the front-end collision test of the vehicle, the structural strength of the hood along the front-to-back direction is increased, which is more conducive to achieving better results in the front-end collision test of the vehicle.

[0082] In addition, refer to Figure 4 , Figure 5 and Figure 6As shown, it needs to be further explained that when the front side of the hood is subjected to external impact, the first support plate 300 and the second support plate 400 abut against each other along the front-to-back direction, but when no collision occurs, the first support plate 300 and the second support plate 400 are not necessarily in a state of abutting against each other. Specifically, when no collision occurs, the first support plate 300 and the second support plate 400 can directly abut against each other along the front-to-back direction. As another embodiment, when no collision occurs, there is a gap between the first support plate 300 and the second support plate 400 along the front-to-back direction, but when a collision occurs, the hood undergoes a certain deformation along the front-to-back direction, and the first support plate 300 and the second support plate 400 abut against each other. In this case, the hood needs to undergo a certain deformation so that the first support plate 300 and the second support plate 400 can abut against each other to enhance the structural strength of the hood, which is more suitable for scenarios when the vehicle undergoes a more serious collision.

[0083] The first support plate 300 and the second support plate 400 abut against each other, which means that the first support plate 300 and the second support plate 400 are in an interlocking state, have an interlocking force, and the first support plate 300 and the second support plate 400 can form an interlocking force through their own structural strength, further increasing the structural strength of the engine hood. As another embodiment, the first support plate 300 abuts against the second support plate 400, and the second support plate 400 does not abut against the first support plate 300; or the second support plate 400 abuts against the first support plate 300, and the first support plate 300 does not abut against the second support plate 400.

[0084] In this embodiment, along the front-to-back direction, the first support plate 300 is limited to the first reinforcement plate 100, the second support plate 400 is limited to the second reinforcement plate 200, and the first support plate 300 and the second support plate 400 abut against each other, so that the three connection positions between the first reinforcement plate 100, the first support plate 300, the second support plate 400 and the second reinforcement plate 200 can all resist the impact along the front-to-back direction. Along the front-to-back direction, the first reinforcement plate 100, the first support plate 300, the second support plate 400 and the second reinforcement plate 200 can be regarded as a whole to resist the impact force in the front-to-back direction as a whole, thereby greatly improving the structural strength of the engine hood along the front-to-back direction.

[0085] Reference Figure 4 , Figure 5 and Figure 6 As shown, in some specific embodiments of the present utility model, the first support plate 300 includes a first main body portion 330, a first limiting portion 340 and a first embedding space 350, both connected to one end of the first main body portion 330 along the left-right direction, and the second support plate 400 includes a second main body portion 410, and a second limiting portion 420 both connected to one end of the second main body portion 410 along the left-right direction;

[0086] Along the left-right direction, the second limiting portion 420 is disposed in the first embedding space 350;

[0087] Along the front-to-back direction, the first limiting portion 340 can abut against the second limiting portion 420;

[0088] Along the up-down direction, a first deformation position 500 is formed between the first position limiting portion 340 and the second position limiting portion 420 , and / or a first deformation position 500 is formed between the first position limiting portion 340 and the second main body portion 410 .

[0089] It is worth understanding that the second limiting portion 420 is disposed in the first embedding position 350, and the first limiting portion 340 and the second limiting portion 420 abut against each other in the front-to-back direction, thereby enhancing the structural strength of the engine hood in the front-to-back direction. At the same time, there is a first deformation position 500 suitable for deformation of the engine hood between the first limiting portion 340 and the second limiting portion 420, thereby making it easier for the engine hood to deform in the up-and-down directions through the first deformation position 500, thereby improving the pedestrian protection capability of the engine hood.

[0090] In this embodiment, the first limiting portion 340 and the second limiting portion 420 are in surface contact with each other. Figure 4 As shown, one side of the first limiting portion 340 abuts against one side of the second limiting portion 420; or, referring to Figure 5 As shown, the first embedding space 350 is between the two first limiting portions 340, the second limiting portion 420 is placed between the two first limiting portions 340, and the two opposite surfaces of the second limiting portion 420 are respectively in contact with one surface of a first limiting portion 340; or, referring to Figure 6 As shown, the first limiting portion 340 is hook-shaped, and the second limiting portion 420 is also hook-shaped, and the first limiting portion 340 and the second limiting portion 420 are hooked and abutted.

[0091] Reference Figure 1 As shown, in some other embodiments of the present invention, the first support plate 300 is connected to the first reinforcement plate 100 , and / or the second support plate 400 is connected to the second reinforcement plate 200 .

[0092] It is worth understanding that the first support plate 300 is connected to the first reinforcement plate 100 along the front-to-back direction, so that the first support plate 300 is limited to the first reinforcement plate 100, thereby increasing the connection strength between the first support plate 300 and the first reinforcement plate 100; the second support plate 400 is connected to the first reinforcement plate 100 along the front-to-back direction, so that the second support plate 400 is limited to the second reinforcement plate 200, thereby increasing the connection strength between the second support plate 400 and the second reinforcement plate 200, thereby increasing the support strength of the first support plate 300 and the second support plate 400 for the engine hood, and the engine hood outer panel 600 can have a higher strength; when the support strength of the engine hood increases, the support strength of the engine hood can be reduced to an appropriate value by reducing the thickness of the first support plate 300, the second support plate 400, the first reinforcement plate 100 and the second reinforcement plate 200; at this time, the engine hood reinforcement structure reduces the use of materials, thereby achieving cost reduction; reduces weight, thereby achieving lightweight; increases structural strength, and improves performance.

[0093] Specifically, the first support plate 300 and the first reinforcing plate 100 may be connected by welding or bolts; the second support plate 400 and the second reinforcing plate 200 may be connected by welding or bolts. In this embodiment, the first support plate 300 is located in the upper space of the first reinforcing plate 100 in the up-down direction, and the first reinforcing plate 100 is located on the side of the first support plate 300 away from the second support plate 400. The first support plate 300 is provided with a first extension plate 360 ​​that is inclined downward and extends toward the first reinforcing plate 100. The first reinforcing plate 100 is provided with a second extension plate 110 that is inclined upward and extends toward the first support plate 300. The first extension plate 360 ​​is connected by welding or bolts. The second support plate 400 is also provided with a third extension plate, and the second reinforcing plate 200 is also provided with a fourth extension plate. The third extension plate is connected by welding or bolts.

[0094] In other embodiments of the utility model, along the up-down direction, there is a second deformation position suitable for deformation of the engine hood between the first support plate 300 and the first reinforcement plate 100, and / or, along the up-down direction, there is a third deformation position suitable for deformation of the engine hood between the second support plate 400 and the second reinforcement plate 200; the support assembly is also configured as follows: when the top surface of the engine hood is subjected to external impact, along the up-down direction, the engine hood is suitable for deformation at the second deformation position, and / or, along the up-down direction, the engine hood is suitable for deformation at the third deformation position.

[0095] It is worth understanding that the hood is more likely to deform in the up and down directions at the first deformation position 500, the second deformation position and the third deformation position to form a buffer, and the hood has multiple positions that are easily deformed by impact, further improving the pedestrian protection capability.

[0096] Among them, the various specific structures of the second deformation position and the third deformation position are the same as the various specific structures of the first deformation position 500, and are only briefly described here. The second deformation position can be formed at intervals or in connection. When the connection is formed, the connection strength of the second deformation position is low and deformation is easy to occur; the third deformation position can be formed at intervals or in connection. When the connection is formed, the connection strength of the third deformation position is low and deformation is easy to occur.

[0097] The second embodiment of the utility model provides a hood reinforcement structure, comprising: a first reinforcement plate 100, a second reinforcement plate 200 and a support plate, wherein the first reinforcement plate 100 and the second reinforcement plate 200 are both used to connect the hood lock structure of the hood to strengthen the structural strength of the hood lock structure, and the first reinforcement plate 100 and the second reinforcement plate 200 are arranged at intervals in the left-right direction; the support plate is arranged between the first reinforcement plate 100 and the second reinforcement plate 200, and the support plate has a first connection portion and a second connection portion in the left-right direction, and the first connection portion is limited to the first reinforcement plate 100 and / or the second connection portion is limited to the second reinforcement plate 200 in the front-back direction; Along the up-down direction, there is a fourth deformation position suitable for deformation of the hood between the first connection part and the first reinforcement plate 100, and / or, there is a fifth deformation position suitable for deformation of the hood between the second connection part and the second reinforcement plate 200; the support plate is configured as follows: when the front side of the hood is subjected to external impact, along the front-to-back direction, the first connection part is limited to the first reinforcement plate 100, and / or, the second connection part is limited to the second reinforcement plate 200; the support plate is also configured as follows: when the top surface of the hood is subjected to external impact, along the up-down direction, the hood is suitable for deformation at the fourth deformation position, and / or, the hood is suitable for deformation at the fifth deformation position.

[0098] In this embodiment, the support plate is an integral structure, which is equivalent to the first support plate 300 and the second support plate 400 in the first embodiment being connected as one body. A first connection portion is provided at one end of the support plate in the left-right direction, and a second connection portion is provided at the other end. The first connection portion is a plate-like structure that is inclined downward and extends toward the first reinforcing plate 100, and the second connection portion is a plate-like structure that is inclined downward and extends toward the second reinforcing plate 200. The fourth deformation position can be formed at intervals or connected. When the connection is formed, the connection strength of the second deformation position is low and deformation is easy to occur; the fifth deformation position can be formed at intervals or connected. When the connection is formed, the connection strength of the third deformation position is low and deformation is easy to occur.

[0099] The first connection portion is limited to the first reinforcing plate 100, and the second connection portion is limited to the second reinforcing plate 200. The first reinforcing plate 100 and the second reinforcing plate 200 are both connected to the vehicle body through a hood lock structure. The support plate can enhance the ability to resist deformation along the front-to-back direction by limiting the first reinforcing plate 100 and the second reinforcing plate 200, thereby improving the structural strength of the engine hood along the front-to-back direction.

[0100] For ease of understanding, in combination with a specific scenario when the front end of a vehicle collides, an example is given in which the first connection portion is limited to the first reinforcing plate 100 and the second connection portion is limited to the second reinforcing plate 200, and an exemplary description is given as follows: when a collision occurs at the front end of the vehicle and the front side of the engine hood is impacted in the front-to-back direction, the first reinforcing plate 100 and the second reinforcing plate 200 are both connected to the vehicle body through the hood lock structure, and in the front-to-back direction, the first connection portion is limited to the first reinforcing plate 100, and the first connection portion transmits the impact to the vehicle body through the first reinforcing plate 100 and the hood lock structure, and the second connection portion is limited to the second reinforcing plate 200, and the second connection portion transmits the impact to the vehicle body through the second reinforcing plate 200 and the hood lock structure, so that the ability of the engine hood to resist deformation in the front-to-back direction is enhanced, thereby increasing the structural strength of the engine hood in the front-to-back direction;

[0101] The engine hood can be deformed more easily in the up and down directions through the fourth deformation position and the fifth deformation position to form a buffer, thereby improving the pedestrian protection capability of the engine hood.

[0102] For ease of understanding, in combination with the specific scenario of the vehicle pedestrian protection test, an exemplary explanation is given as follows: in the vehicle pedestrian protection test, the legs of the pedestrian are hit by the front end of the vehicle, causing the pedestrian to fall toward the hood, and the pedestrian's head will collide with the top surface of the hood. When the pedestrian's head collides with the top surface of the hood, the hood is subjected to a downward impact force, and the hood is more likely to deform downward through the fourth deformation position and the fifth deformation position to form a buffer, thereby reducing the damage to the pedestrian and improving the hood's ability to protect pedestrians.

[0103] Reference Figure 4 , Figure 5 and Figure 6As shown, the third aspect of the utility model proposes a hood reinforcement structure, including a support assembly, the support assembly includes a first support plate 300 and a second support plate 400, along the front-to-back direction, the first support plate 300 can abut against the second support plate 400, along the up-down direction, there is a first deformation position 500 suitable for deformation of the hood between the first support plate 300 and the second support plate 400; the support assembly is configured as: when the front side of the hood is subjected to an external impact, along the front-to-back direction, the first support plate 300 and the second support plate 400 abut against each other; the support assembly is also configured as: when the top surface of the hood is subjected to an external impact, along the up-down direction, the hood is suitable for deformation at the first deformation position 500.

[0104] It is worth understanding that when a collision occurs at the front end of the vehicle and the front side of the hood is impacted in the front-to-back direction, the first support plate 300 and the second support plate 400 abut against each other in the front-to-back direction, and the ability of the support assembly to resist deformation in the front-to-back direction is enhanced, thereby increasing the structural strength of the hood in the front-to-back direction; in the pedestrian protection test of the vehicle, the legs of the pedestrian are hit by the front end of the vehicle, causing the pedestrian to fall toward the hood, and the pedestrian's head will collide with the top surface of the hood. When the pedestrian's head collides with the top surface of the hood, the hood is subjected to a downward impact force, and the hood is more likely to deform downward through the first deformation position 500 to form a buffer, thereby reducing the damage to the pedestrian and improving the hood's ability to protect the pedestrian.

[0108] It is worth understanding that the hood of the fourth aspect embodiment adopts the hood reinforcement structure of the first aspect embodiment or the second aspect embodiment or the third aspect, which enhances the structural strength of the hood along the front and rear directions, while improving the hood's ability to protect pedestrians' heads.
