DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] like Figures 1 to 6 As shown, an embodiment of the present invention provides an engine hood, comprising an outer panel 6, an inner panel 1, an outer panel reinforcement panel 2, and a lock reinforcement panel 3. The lock reinforcement panel 3 comprises a lock reinforcement panel body 31 and a flange 32 connected to the outer edge of the lock reinforcement panel body 31. The lock reinforcement panel body 31 is fixed to the inner panel 1, and a gap 8 is formed between the flange 32 and the inner panel 1.

[0028] The outer panel reinforcement plate 2 includes an outer panel reinforcement plate body 21 fixed to the outer panel 6 and a plurality of legs 22 extending from the outer panel reinforcement plate body 21 in a direction away from the outer panel 6. Some of the legs 22 are fixed to the inner panel 1, and some of the legs 22 are fixed to the flange 32. The top, bottom, front side, and rear side involved in this application refer to the up, down, front, and rear directions when the engine hood is closed on the vehicle body and a person is sitting in the driver's seat of the vehicle, with the person as the reference, and other directions are based on this reference. In this embodiment, the inner panel 1 and the outer panel 6 are connected together by edging, the lock reinforcement plate body 31 is welded to the inner panel 1, and the outer panel reinforcement plate 2 is connected to the outer panel 6 by gluing. A sufficient gap 8 is left between the flange 32 and the inner panel 1. At the same time, the flange 32 is welded to the outer panel reinforcement plate 2. In this embodiment, the lock reinforcement plate body 31 can be entirely attached to the inner panel 1, or only part of the structure of the lock reinforcement plate body 31 can be attached to the inner panel 1, and the remaining part has a gap 8 with the inner panel 1. When the engine hood hits a pedestrian, the part attached to the inner panel 1 and the flange 32 together form a buffer structure similar to a seesaw, further ensuring the safety of the pedestrian when hit. In other embodiments, the lock reinforcement plate 3 is provided with a through hole, and the lock reinforcement plate body 31 is fixed to the inner panel 1 by bolts and nuts. The engine hood of this embodiment can greatly enhance the pedestrian protection performance and reduce the damage to pedestrians caused by collisions while ensuring strength, rigidity and durability. In addition, the manufacturing process of this structure is relatively simple and easy, with high feasibility and great market potential. In this embodiment, the end of the leg 22 away from the outer panel 6 is folded outward to form a hem. The leg 22 is connected to the flange 32 and the inner panel 1 through the hem. This increases the contact area between the corresponding portion of the leg 22 and the inner panel 1, as well as the contact area between the corresponding portion of the leg 22 and the flange 32. This can increase the stability of the connection between the corresponding portion of the leg 22 and the inner panel 1, as well as the stability between the corresponding portion of the leg 22 and the flange 32, thereby ensuring a cushioning effect. Furthermore, in this embodiment, the leg 22 is inclined toward the outside of the outer panel reinforcement plate 2 in the direction from the outer panel 6 to the inner panel 1, which can further enhance the cushioning effect and thereby ensure pedestrian safety.

[0029] In one embodiment, the inner panel 1 is fixed to the bottom side of the outer panel 6. A buffer space is defined between the front side of the outer panel 6 and the front side of the inner panel 1. The outer panel reinforcement plate 2 and the latch reinforcement plate 3 are disposed in the buffer space. The hood (engine cover) is a key component of a vehicle's engine compartment. Its primary function is to protect the engine and its components from external factors such as debris, dust, water, and extreme weather conditions. In addition to protecting the engine, the hood also plays a vital role in ensuring the safety of vehicle occupants and pedestrians. Existing hoods generally consist of the outer panel 6, the inner panel 1, the latch reinforcement plate 3, and the outer panel reinforcement plate 2. A buffer space is formed between the front side of the outer panel 6 and the front side of the inner panel 1. The outer panel reinforcement plate 2 and the latch reinforcement plate 3 are disposed in the buffer space. In the event of a head-on collision, the hood's buffer space and the outer panel reinforcement plate 2 disposed therein act as a crumple zone. Upon impact, the crumple zone absorbs the impact force, deforms, and reduces the severity of the collision. This energy-absorbing mechanism disperses the impact force away from pedestrians, reducing the risk of serious injury. Furthermore, in this embodiment, when the front side of the hood collides with a pedestrian, the portion where the inner panel 1 is in contact with the flange 32 forms a buffer structure similar to a seesaw, which can enhance the pedestrian protection performance to a greater extent while ensuring the strength, rigidity and durability, and reduce the damage to pedestrians caused by collisions.

[0030] In one embodiment, the outer panel reinforcement plate body 21 and the latch reinforcement plate body 31 are spaced apart and arranged opposite to each other. In this embodiment, a certain space is left between the outer panel reinforcement plate body 21 and the latch reinforcement plate body 31. When the latch 10 of the hood collides with a pedestrian, if the impact force is large, the support leg 22 undergoes plastic deformation, which can further provide a buffer space and reduce damage to the pedestrian.

[0031] In one embodiment, the plurality of legs 22 include a plurality of first legs 221 and a plurality of second legs 222 ;

[0032] A plurality of first legs 221 are connected to the front side of the outer panel reinforcement plate body 21 , some of the first legs 221 are fixed to the inner panel 1 , and some of the first legs 221 are fixed to the front side of the flange 32 ;

[0033] Multiple second legs 222 are connected to the rear side of the outer panel reinforcement plate body 21. Some of the second legs 222 are fixed to the inner panel 1, and some of the second legs 222 are fixed to the rear side of the flange 32. In this embodiment, legs 22 are provided on both the front and rear sides of the outer panel reinforcement plate 2. The multiple first legs 221 provided on the front side of the outer panel reinforcement plate 2 are spaced apart from each other, while the multiple second legs 222 provided on the rear side of the outer panel reinforcement plate 2 are spaced apart from each other. This ensures the stability of the connection between the outer panel reinforcement plate 2 and the flange 32, further ensuring the cushioning effect and protecting pedestrians after an impact.

[0034] In one embodiment, along the extension direction of the legs 22, the cross-sectional area of the first leg 221 fixed to the inner panel 1 is smaller than the cross-sectional area of the second leg 222 fixed to the inner panel 1. In this embodiment, the front side of the buffer space is larger than the rear side, and the second leg 222 connected to the inner panel 1 is larger than the first leg 221 connected to the inner panel 1. This ensures that the connection between the second leg 222 and the inner panel 1 is stronger than the connection between the first leg 221 and the inner panel 1. When the hood latch 10 strikes a pedestrian, the first leg 221 connected to the inner panel 1 undergoes plastic deformation first, thereby creating a larger buffer space and further ensuring pedestrian safety. Furthermore, the second leg 222 fixed to the inner panel 1 is provided with a weight-reducing hollow structure.

[0035] In one embodiment, the rear side of the flange 32 includes multiple folded portions 321 spaced apart from each other, each folded portion 321 having a support leg 22. In this embodiment, the multiple spaced folded portions 321 form a relief area, ensuring that the flange 32 of this embodiment does not interfere with the installation of the original structure of the inner panel 1. Furthermore, the front, left, and right sides of the flange 32 of this embodiment are continuous folded structures, ensuring a buffering effect between the outer panel 6, the outer panel reinforcement plate 2, the flange 32, and the inner panel 1.

[0036] In one embodiment, weakened and weight-reducing holes 9 are provided on the inner panel 1, the outer panel reinforcement plate body 21, and the latch reinforcement plate 3. In this embodiment, when the hood latch 10 strikes a pedestrian, this facilitates plastic deformation of the corresponding structures, further reducing injuries sustained by the pedestrian. Furthermore, the outer panel reinforcement plate body 21 is elongated and has a groove for adhesive. The adhesive is placed in the groove and connects the outer panel reinforcement plate 2 to the outer panel 6.

[0037] In one embodiment, a lock 10 is provided on the lock reinforcement plate 3, and a through hole matching the lock 10 is provided on the inner plate 1, and the lock 10 is installed in the through hole.

[0038] In one embodiment, the engine hood also includes a hinge 5 and a hinge reinforcement plate 4, the hinge reinforcement plate 4 is installed on the bottom side of the inner panel 1, and the hinge 5 is installed on the hinge reinforcement plate 4; or, the hinge reinforcement plate 4 is installed on the top side of the inner panel 1, the bottom side of the inner panel 1 has an installation area opposite to the hinge reinforcement plate 4, and the hinge 5 is installed on the installation area of the hinge reinforcement plate 4.

[0039] According to the engine hood of this embodiment, by fixing the lock reinforcement plate body 31 to the inner panel 1 and setting a gap 8 between the flange 32 and the inner panel 1, when the lock 10 of the engine hood hits a pedestrian, the outer panel 6 is subjected to an impact force, and the impact force on the outer panel 6 is transmitted to the flange 32 through the outer panel reinforcement plate 2. The flange 32 is forced to move toward the direction of the inner panel 1. At the same time, the lock reinforcement plate body 31 is fixed and plays a supporting role, so that a buffer structure is formed between the outer panel reinforcement plate 2, the flange 32, the lock reinforcement plate 3 and the inner panel 1 of this embodiment, thereby reducing the damage to pedestrians. In addition, during the opening and closing process, the buffer structure formed between the outer panel reinforcement plate 2, the flange 32, the lock reinforcement plate 3 and the inner panel 1 of this embodiment can disperse the force at the lock 10 of the lock reinforcement plate 3, thereby reducing the occurrence of cracking problems.

[0040] In addition, an embodiment of the present invention provides a vehicle, comprising the engine hood of the above embodiment.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
