Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to an engine hood and a vehicle. Background Art

[0002] With the rapid economic growth, the automobile industry has developed rapidly, the per capita car ownership has continued to increase, the number of vehicles on the road has increased, and the safety threat to pedestrians has gradually increased. Therefore, the safety requirements for automobiles have become increasingly stringent. In order to meet the requirements of reducing the harm to pedestrians when the car collides head-on with pedestrians, the car needs to have a star-level pedestrian protection function. In related technologies, in order to improve strength, the vehicle engine hood is often designed as a multi-main rib structure, such as Figure 1 As shown in the figure, H0 is the height of the main rib. In the prior art, the height of the main rib is usually set relatively large, usually up to 20 mm. This multi-main rib structure can improve the overall rigidity of the engine hood, but due to the excessive height of the main rib, a relatively strong bending structure is formed on the engine inner plate. In addition, the main rib area is too large and the position is centered. When a car collides with a pedestrian head-on, the human head often hits the main rib area, causing great damage to the human body, and it is difficult for the vehicle to meet the pedestrian protection requirements.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0040] like Figure 2 and Figure 4 As shown, an engine hood according to an embodiment of the present invention includes an outer panel 110 and an inner panel 120 .

[0041] Specifically, the inner panel 120 is arranged on the inner side of the outer panel 110 (i.e., the side of the outer panel 110 facing the vehicle body), and the inner panel 120 includes an inner panel frame 124 and three connecting ribs. The inner panel frame 124 is connected to the outer panel 110, and a central hollow portion 121 and three connecting ribs are opened on the inner panel frame 124. The central hollow portion 121 extends along the left and right directions of the engine hood (such as Figure 2 The inner panel frame 124 is extended in the left-right direction (in the left-right direction shown in FIG. 1 ) to form an annular shape to reduce the rigidity of the middle area of ​​the engine hood. Thus, the impact force on the pedestrian is reduced during the collision between the vehicle and the pedestrian. In addition, the provision of the central hollow portion 121 also reduces the weight of the inner panel 120.

[0042] like Figure 2 and Figure 3 As shown, the cross section of the connecting rib is flat, and three connecting ribs are arranged in the central hollow portion 121 from left to right in sequence, and the two ends of the connecting ribs are respectively connected to the front edge and the rear edge of the central hollow portion 121. In this way, the structure of the inner plate frame 124 can be strengthened and its torsion resistance can be improved. Figure 1 As shown, Figure 1 It is a schematic diagram of the main ribs 002 on the engine hood outer panel 001 and the engine inner panel in the prior art, and H0 in the figure is the height of the main ribs 002. In the prior art, most engine hoods adopt the traditional multi-main rib 002 support structure, and the height of the main ribs 002 is usually set relatively large, usually up to 20mm. This multi-main rib 002 structure can improve the overall rigidity of the engine hood, but because the height of the main ribs 002 is too large, a relatively strong bending structure is formed on the engine inner panel 001, and the area of ​​the main ribs 002 on the engine hood is too large and the position is centered. When the front of the car collides with a pedestrian, it happens to be the human head impact area, resulting in a high human injury value. The cross-section of the connecting rib of the present application is flat. Compared with the prior art, it can avoid the excessive strength of the local area on the inner panel and cause serious harm to the human body, thereby improving the protection of pedestrians, and the connecting ribs can also improve the torsional resistance of the inner panel frame 124. It should be noted that if Figure 2 As shown in , the front and rear directions described in this article are based on the vehicle driving direction as the front direction and the direction opposite to the vehicle driving direction as the rear direction.

[0043] like Figure 2 As shown, when observing along the top view of the inner panel, the ratio of the area of ​​the central hollow portion 121 to the total area of ​​the inner panel is greater than 50%. When a vehicle collides with a pedestrian, the probability of collision between the human body and the solid part of the inner panel 120 can be reduced, thereby reducing the collision damage to the human body.

[0044] According to the engine hood of the embodiment of the present invention, the inner plate frame 124 is annular through the central hollow portion 121, and when viewed from the top view of the inner plate, the ratio of the area of ​​the central hollow portion to the total area of ​​the inner plate is greater than 50%, so as to reduce the rigidity of the middle area of ​​the engine hood, reduce the probability of collision between the human body and the solid part of the inner plate, reduce the impact force on pedestrians during the collision, and reduce the weight of the inner plate 120. At the same time, the connecting ribs connect the front edge and the rear edge of the central hollow portion, and the cross section of the connecting ribs is flat, which not only improves the torsion resistance of the inner plate frame 124, but also avoids excessive local strength of the inner plate, reducing the damage to pedestrians during collision.

[0045] like Figure 5 As shown, according to some embodiments of the present invention, the engine hood further includes a reinforcing plate 130, which is disposed between the outer panel 110 and the inner panel 120. The reinforcing plate 130 is connected to the outer panel 110 and is located in front of the central hollow portion 121. The reinforcing plate 130 abuts against the outer panel 110 to support the outer panel 110, improve the local strength of the outer panel 110, improve the NVH performance of the engine hood, and reduce vibration and noise during vehicle driving. The load-bearing capacity of the outer panel 110 is also improved, and when a person sits on the engine hood, the outer panel 110 will not be significantly deformed. Figure 2 As shown, the reinforcing plate 130 is located at the front side of the central hollow portion 121. Compared with the rear side of the outer plate 110, the reinforcing plate 130 is closer to the front side of the outer plate 110. When a collision occurs with a pedestrian, the probability of collision between the pedestrian and the reinforcing plate 130 can be reduced. The reinforcing plate 130 not only improves the strength of the outer plate 110, but also reduces the damage caused to the pedestrian. Figure 2 As shown, in some embodiments, the distance between the center of the reinforcing plate 130 and the front edge of the outer plate 110 is W1, the front-to-back width of the outer plate 110 is W, and W1=1 / 3W.

[0046] The reinforcing plate 130 includes a plate body 131 and at least two supporting feet, at least two supporting feet are arranged at intervals along the outer periphery of the plate body 131, the plate body 131 is connected to the outer plate 110 through the supporting feet, and the plate body 131 fits the outer plate 110 to support the outer plate 110. The supporting feet and the plate body 131 can be an integrally formed part, or the supporting feet can be welded to the plate body 131. The supporting feet are connected to the outer plate 110, and the supporting feet and the outer plate 110 can be welded. The plate body 131 and the outer plate 110 are against each other to support the outer plate 110. In some implementations, reinforcing ribs can be provided on the supporting feet to improve the stability of the reinforcing plate 130, and the reinforcing ribs can be triangular.

[0047] like Figure 5 and Figure 6As shown, according to some embodiments of the present invention, support feet are respectively provided along the front edge and the rear edge of the plate body 131, and the support feet located at the front edge of the plate body 131 are called front support feet 132, and the support feet located at the rear edge of the plate body 131 are called rear support feet 133. The front support feet 132 and the lower surface of the plate body 131 (such as Figure 6 The angle between the front support leg 132 and the front support leg 132 is A1, which is an obtuse angle. On the one hand, it can prevent the reinforcement plate 130 from forming a sharp angle and causing secondary damage to pedestrians. On the other hand, when a collision occurs with a pedestrian, it is convenient for the front support leg 132 to deform and absorb the impact force to protect the pedestrian. Specifically, 150°≤A1≤170°, for example, A1 can be 150°, 155°, 160° or 170°, etc. Figure 6 As shown, the front support foot 132 is more likely to deform under a smaller force, and is more likely to absorb more energy, greatly reducing the damage to pedestrians. When a vehicle collides with a pedestrian, and a pedestrian collides with the engine hood, the reinforcement plate 130 is subjected to the impact force (such as Figure 6 As shown by the middle arrow F), the connection between the front support leg 132 and the plate body 131 is easily bent and deformed to absorb the energy of the collision and reduce the damage to the pedestrian.

[0048] In some embodiments, the angle between the rear support leg 133 and the plate body 131 can be an obtuse angle to avoid forming a sharp angle and causing secondary damage to pedestrians, and it is easy to deform in the event of a collision to reduce the damage to pedestrians. The angle between the rear support leg 133 and the plate body 131 is A2, 90°<A2≤120°, for example, A2 can be 100°, 110°, 115° or 120°. This ensures the connection strength between the rear support leg 133 and the plate body 131 and improves the strength of the reinforcing plate 130.

[0049] like Figure 5 As shown, according to some embodiments of the present invention, the plate body 131 is provided with at least one second avoidance hole 1311, so that the plate body 131 forms a frame structure, reduces the area of ​​the plate body 131, and reduces the probability of collision with pedestrians. Figure 5 In the example, two second avoidance holes 1311 are provided on the plate body 131 .

[0050] like Figure 4 As shown, according to some embodiments of the present invention, the engine hood further comprises a latch 140, which is used to be connected to the vehicle body. The latch 140 is detachably connected to the vehicle body to lock or unlock the engine hood and the vehicle body. Figure 2As shown, the connecting rib located in the middle of the inner plate 120 among the three connecting ribs is the first connecting rib 122, and the other two connecting ribs are the second connecting ribs 123. The two second connecting ribs 123 are respectively located on the left and right sides of the first connecting rib 122. The first connecting rib 122 is provided with a mounting portion 125, and the lock buckle 140 is fixedly connected to the mounting portion 125. The mounting portion 125 can provide a mounting and fixing position for the lock buckle 140, thereby improving the installation stability of the lock buckle 140. The mounting portion 125 is recessed in a direction away from the outer plate 110 to increase the distance between the lock buckle 140 and the outer plate 110, reduce the probability of the lock buckle 140 colliding with a pedestrian during a collision, and improve the protection of pedestrians. In some embodiments, the distance L between the mounting portion 125 and the outer plate 110 is greater than or equal to 45 mm. For example, L can be 45 mm, 50 mm, 55 mm, 70 mm, etc.

[0051] like Figure 2 As shown, according to some embodiments of the present invention, the mounting portion 125 is located in front of the first connecting rib 122, and a first avoidance hole 1221 is provided in the rear of the first connecting rib 122 to reduce the area of ​​the first connecting rib 122, so as to avoid pedestrians in the event of a collision and reduce the damage to pedestrians. Figure 2 As shown, the reinforcing plate 130 is located in the length direction of the outer plate 110 (eg Figure 2 The reinforcing plate 130 is located in the middle of the outer panel 110 in the left-right direction (as shown in FIG. 1 ) and in the front side of the outer panel 110. The orthographic projection of the reinforcing plate 130 on the plane where the inner panel 120 is located falls on the mounting portion 125 and the first connecting rib 122. Thus, the strength of the outer panel 110 is improved, and the probability of collision between the reinforcing plate 130 and pedestrians is reduced.

[0052] like Figure 2 and Figure 7 As shown, according to some embodiments of the present invention, the engine hood further includes a connecting hinge, a hinge reinforcement 150 and a fixing member 152. The hinge reinforcement 150 is provided on the side of the inner panel 120 facing the outer panel 110 and is connected to the inner panel 120 through the fixing member 152. One end of the connecting hinge is connected to the vehicle body, and the other end is connected to the hinge reinforcement 150 and the inner panel 120. The hinge reinforcement 150 can improve the connection strength between the connecting hinge and the inner panel 120. The fixing member 152 includes a column 153 and a plate-shaped abutment cap 154. The hinge reinforcement 150 is provided with a mounting groove 151. The opening of the mounting groove 151 faces the outer panel 110. The column 153 is penetrated through the bottom of the mounting groove 151 and the inner panel 120. The abutment cap 154 ​​is located in the mounting groove 151 and abuts against the bottom of the mounting groove 151. Thus, the mounting groove 151 can receive the abutment cap 154, and when a collision occurs, the damage caused to the pedestrian by the abutment cap 154 ​​is reduced. The abutment cap 154 ​​can be disc-shaped to reduce the damage caused to the pedestrian.

[0053] A vehicle according to an embodiment of the present invention comprises a vehicle body and an engine hood as described above, wherein the engine hood is rotatably connected to the vehicle body. Specifically, both left and right ends of the rear side of the engine hood are rotatably connected to the vehicle body via connecting hinges, such as Figure 2 As shown, hinge reinforcements 150 are provided at the left and right ends of the rear side of the hood corresponding to the connection hinges to improve the stability of the connection between the connection hinge and the inner panel 120. The front side of the hood is detachably connected to the vehicle body through a lock 140, and the hood and the vehicle body can be locked or unlocked.

[0054] In summary, the embodiment of the present invention provides an engine hood, which has at least the following beneficial effects:

[0055] 1. The strength of the middle area of ​​the hood is reduced, which can reduce the damage to pedestrians in the event of a collision;

[0056] 2. The strength of the outer panel 110 is improved by the reinforcement panel 130, and the front support leg 132 of the reinforcement panel 130 is easily deformed during a collision to absorb the energy of the collision, thereby reducing the damage to pedestrians.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
