[0029] The hood, a crucial component of a vehicle, consists primarily of an outer panel and an inner panel. During the actual design process, R&D personnel discovered that to ensure the hood's structural strength and prevent deformation when pressed manually, a reinforcement plate is typically added directly between the outer and inner panels to increase the thickness of the outer panel's front end. While this increases the hood's structural strength and prevents deformation, it also increases its weight, potentially increasing the risk of pedestrian injury in the event of a collision, particularly when a pedestrian's head strikes the front end of the hood.
[0030] The utility model provides an engine hood and a vehicle, aiming to solve the technical problem that the engine hood is very likely to cause serious damage to pedestrians when a collision occurs due to the large thickness and weight of the outer plate of the existing engine hood.
[0031] See also Figure 1 and Figure 2 In one embodiment of the present invention, an engine hood is applied to a vehicle, and the engine hood includes an outer panel, an inner panel and a reinforcement panel 100. The outer panel and the inner panel are stacked, and the reinforcement panel 100 is arranged between the outer panel and the inner panel. The reinforcement panel 100 includes a first plate body 110 and a second plate body 120 stacked in a direction from the outer panel to the inner panel. The second plate body 120 includes a first connection portion 121, a second connection portion 122, a third connection portion 123 and a fourth connection portion 124 connected in sequence. The first connection portion 121 is inclined from a side close to the first plate body 110 to a side away from the first plate body 110 along the front and rear direction of the vehicle, and the fourth connection portion 124 is inclined from a side away from the first plate body 110 to a side close to the first plate body 110 along the front and rear direction of the vehicle. The first connection plate, the second connection portion 122, the third connection portion 123, the fourth connection portion 124 and the first plate body 110 are surrounded to form a buffer space 125.
[0032] The technical solution of this utility model is to provide a reinforcement plate 100 between the outer panel and the inner panel. The first connecting plate, second connecting portion 122, third connecting portion 123, and fourth connecting portion 124 of the first plate 110 and the second plate 120 form a buffer space 125. This not only improves the structural strength of the hood, but also reduces the damage to pedestrians who collide with the hood. In this embodiment, the reinforcement plate 100 is provided at the front end of the outer panel and between the outer panel and the inner panel. This improves the structural strength of the hood and reduces the possibility of deformation of the hood when pressed manually. The reinforcing plate 100 includes a first plate body 110 and a second plate body 120, wherein the second plate body 120 is an inverted trapezoidal bent plate, and the second plate body 120 includes a first connecting portion 121, a second connecting portion 122, a third connecting portion 123 and a fourth connecting portion 124 connected in sequence, and the first connecting portion 121, the second connecting portion 122, the third connecting portion 123, the fourth connecting portion 124 and the first plate body 110 enclose a travel buffer space 125, and the buffer space 125 can provide a buffer for the pedestrian when the pedestrian collides with the engine hood, thereby reducing the damage to the pedestrian. Specifically, when the pedestrian collides with the engine hood, the outer plate of the engine hood will sag downward and squeeze the first plate body 110 to drive the first plate body 110 to deform. At this time, due to the existence of the buffer space 125, the first plate body 110 has a larger deformation space and can sag and deform downward, thereby providing a buffer for the pedestrian and reducing the damage to the pedestrian when colliding with the engine hood. The engine hood is applied to technical fields such as vehicles.
[0033] See also Figure 2 In one embodiment of the present invention, let the angle between the first connection portion 121 and the second connection portion 122 be a, the angle between the second connection portion 122 and the third connection portion 123 be b, and the angle between the third connection portion 123 and the fourth connection portion 124 be c, then: 142°≤a≤147°, 114°≤b≤120°, 154°≤c≤160°. In this embodiment, the second plate body 120 is a stamped part, that is, the second plate body 120 is manufactured by stamping; and limiting the angle between the first connection portion 121 and the second connection portion 122, the angle between the second connection portion 122 and the third connection portion 123, and the angle between the third connection portion 123 and the fourth connection portion 124 to the above-mentioned different ranges, on the one hand, facilitates the stamping of the second plate body 120, and on the other hand, can improve the structural strength of the reinforcing plate 100, thereby improving the structural strength of the engine cover. In a specific embodiment, the angle between the first connection portion 121 and the second connection portion 122 is 145°, the angle between the second connection portion 122 and the third connection portion 123 is 117°, and the angle between the third connection portion 123 and the fourth connection portion 124 is 157°.
[0034] In one embodiment of the present invention, let the length of the third connecting portion 123 be d and the length of the fourth connecting portion 124 be e. Then, d < e, and 15 mm ≤ d ≤ 25 mm. In this embodiment, the third connecting portion 123 is the shortest, meaning that the lengths of the first connecting portion 121, the second connecting portion 122, and the fourth connecting portion 124 are all greater than the length of the third connecting portion 123. In other words, the second plate 120 is divided into four sections, with the third connecting portion 123 being the shortest. This facilitates deformation of the fourth connecting portion 124 when the impact force is too great, thereby reducing injuries to the pedestrian. Specifically, when the impact force of a pedestrian colliding with the hood is too great, the buffer space 125 cannot provide sufficient buffer space 125 for the deformation of the first plate 110. In this case, the first plate 110, squeezed by the outer panel, deforms downward, subsequently contacts the fourth connecting portion 124 of the second plate 120, and causes the fourth connecting portion 124 to deform. By minimizing the length of the third connecting portion 123, the fourth connecting portion 124 is more easily deformed during a collision, minimizing injuries to pedestrians. This is particularly effective when a pedestrian's head strikes the hood. In a specific embodiment, to ensure the presence of the third connecting portion 123 and the structural strength of the second plate 120, the length of the third connecting portion 123 is limited to between 15 and 25 mm. In a more specific embodiment, the length of the third connecting portion 123 is 19 mm, and the length of the fourth connecting portion 124 is 84 mm.
[0035] It should be noted that the length of the first connection part 121 refers to the distance between the side of the first connection part 121 away from the second connection part 122 and the side where the first connection part 121 and the second connection part 122 are connected; the length of the second connection part 122 refers to the distance between the side where the second connection part 122 and the first connection part 121 are connected to the side where the second connection part 122 and the third connection part 123 are connected; the length of the third connection part 123 refers to the distance between the side where the third connection part 123 and the second connection part 122 are connected to the side where the third connection part 123 and the fourth connection part 124 are connected; and the length of the fourth connection part 124 refers to the distance between the side where the fourth connection part 124 and the third connection part 123 are connected to the side where the fourth connection part 124 is away from the third connection part 123.
[0036] See also Figure 1In one embodiment of the present invention, the first plate 110 is provided with recessed portions 111 and extended portions 112 spaced apart along the front-to-back direction of the vehicle. The recessed portions 111 are recessed from the first plate 110 toward the second plate 120, while the extended portion 112 extends along the front-to-back direction of the vehicle. The first connecting portion 121 is welded to the extended portion 112, and the fourth connecting portion 124 is welded to the recessed portion 111. Specifically, by welding the fourth connecting portion 124 to the recessed portion 111 and the first connecting portion 121 to the extended portion 112, the second plate 120 is mounted to the first plate 110. This improves the structural strength of the reinforcement plate 100, and thereby the structural strength of the hood. Furthermore, the recessed portions 111 are recessed from the first plate 110 toward the second plate 120, reducing the risk of interference between the recessed portions 111 and the outer panel. In a specific embodiment, there are multiple recessed portions 111 and multiple extending portions 112 , and the multiple recessed portions 111 and the multiple extending portions 112 are spaced apart along the left-right direction of the vehicle.
[0037] See also Figure 1 In one embodiment of the present invention, the first plate 110 is provided with a plurality of bonding portions 117. Each bonding portion 117 protrudes from the first plate 110 in a direction away from the second plate 120, and each bonding portion 117 is bonded to the outer panel. Specifically, when the reinforcing panel 100 is installed between the outer panel and the inner panel, the bonding portion 117 of the first plate 110 is bonded to the outer panel to complete the installation of the first plate 110. This simple and convenient installation process can reduce the difficulty of installing the first plate 110, and thus reduce the difficulty of installing the reinforcing panel 100. The bonding portions 117 protrude from the first plate 110 in a direction away from the second plate 120, providing multiple bonding planes for bonding the outer panel. This not only allows the first plate 110 to be more securely bonded to the outer panel, but also reduces the use of materials such as adhesives (such as glue), thereby reducing production costs. In a specific embodiment, the plurality of bonding portions 117 are irregularly distributed, and each bonding portion 117 is an elliptical protrusion.
[0038] Accordingly, the first plate 110 is provided with a first weld 113 and a second weld 114 on either side of the vehicle's front-to-back direction. Both the first weld 113 and the second weld 114 are welded to the inner panel. Specifically, there are multiple first welds 113, spaced apart along the left-right direction of the vehicle, and each first weld 113 extends along the front-to-back direction of the vehicle. There are two second welds 114, one located on either side of the extension 112. In one specific embodiment, the second welds 114 are provided at the two corners on the rear side of the first plate 110.
[0039] See also Figure 1In one embodiment of the present invention, a groove 115 is provided between the recessed portion 111 and the adjacent adhesive portion 117, as well as between any two adjacent adhesive portions 117. The groove 115 is recessed from the first plate 110 toward the second plate 120. Specifically, the groove 115 provided between the recessed portion 111 and the adjacent adhesive portion 117, as well as between any two adjacent adhesive portions 117, is used to enhance the structural strength of the first plate 110, thereby enhancing the structural strength of the reinforcing plate 100 and the engine cover. It should be noted that the groove 115 is a reinforcing rib structure, primarily forming multiple reinforcing ribs extending in the transverse or longitudinal direction on the plate to enhance the structural strength of the plate.
[0040] See also Figure 1 and Figure 3 In one embodiment of the present invention, the first plate 110 is provided with a first weight-reducing hole 116, and the first connecting portion 121 and the fourth connecting portion 124 are both provided with a second weight-reducing hole 1211. Specifically, by providing the first weight-reducing hole 116 in the first plate 110 and the second weight-reducing holes 1211 in the first connecting portion 121 and the fourth connecting portion 124, the weight of the reinforcement plate 100 can be reduced, thereby reducing the weight of the engine cover.
[0041] See also Figure 2 In one embodiment of the present invention, the second connecting portion 122 is provided with a locking hook 1221, and the locking hook 1221 passes through the inner panel. Specifically, when the engine cover is placed above the engine compartment, the locking hook 1221 can cooperate with the lock buckle on the vehicle body to lock the engine cover. In a specific embodiment, the locking hook 1221 is U-shaped, that is, the locking hook 1221 is a U-shaped locking hook 1221. In this embodiment, the inner panel of the engine cover has a stepped accommodating cavity, and the end surface of the inner panel is provided with a plurality of through holes. In other words, the inner panel is a floating island structure, which can reduce the damage to pedestrians in the event of a collision with pedestrians.
