[0002] As an important functional part of a car, the quality of the car cover directly affects the performance of the whole car. The front hood is one of the core parts of the car cover. It is generally composed of a space surface with complex shapes and features, with the characteristics of thin material, large structure size, high precision and performance requirements, and plays a decisive role in the performance of the whole vehicle in the body structure.

[0003] However, when a pedestrian collision occurs, the existing front engine compartment cover is still insufficient in pedestrian protection performance. Therefore, it is necessary to improve the structure of the front engine compartment cover. Utility Model Content

[0004] In view of this, the utility model aims to provide a front engine compartment cover to improve the pedestrian protection performance of the front engine compartment cover.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A front engine compartment cover plate, comprising a front engine compartment cover inner plate and a front engine compartment cover outer plate which are buckled and connected together;

[0007] The left and right sides of the front part of the front bonnet inner plate are provided with collapse holes, the collapse holes on each side are arranged close to the headlights on the same side, and the collapse holes on each side are multiple and arranged at intervals from front to rear along the edge of the front bonnet inner plate.

[0008] Furthermore, both the left and right sides of the front engine cover inner panel have a top wall located at the edge, a side wall connected to the inner side of the top wall, and a bottom wall connected to the inner side of the side wall; along the direction pointing to the bottom wall on the same side, the side walls on each side are arranged inwardly, and the collapse holes on each side are located on the side walls on the same side.

[0009] Furthermore, a distance h between the side wall on each side and the front bonnet outer panel in the vertical direction of the vehicle is within 35 mm.

[0010] Furthermore, the draft angle (θ) of the side wall on each side is greater than 60°, the top wall and the side wall on each side are connected via a first rounded corner, and the side wall and the bottom wall on each side are connected via a second rounded corner.

[0011] Furthermore, the fillet radius R1 of the first fillet is greater than 6 mm, and / or the fillet radius R2 of the second fillet is greater than 12 mm.

[0012] Furthermore, the collapse holes on each side are long holes arranged in the front-rear direction of the vehicle, and both ends of the collapse holes on each side in the length direction penetrate the first fillet and the second fillet on the same side.

[0013] Furthermore, the length direction of each of the collapse holes is perpendicular to the first rounded corner and the second rounded corner at the location.

[0014] Furthermore, a weight-reducing hole is formed in the middle of the inner plate of the front engine cover, and an inner plate reinforcement bracket is provided in the weight-reducing hole, and the inner plate reinforcement bracket divides the weight-reducing hole into a plurality of areas.

[0015] Furthermore, the inner panel reinforcement bracket includes an intermediate bracket located in the middle of the weight-reducing hole in the left and right directions, and side brackets arranged on both sides of the left and right sides of the intermediate bracket; the intermediate bracket extends along the front and rear directions of the vehicle, and the side brackets on both sides include a plurality of cross-connected arms.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The front engine compartment cover described in the utility model is provided with a collapse hole on the inner plate of the front engine compartment cover near the front headlight, that is, the collapse hole is provided at a position which is easy to collide with pedestrians. In this way, when a collision occurs, the collapse deformation at the location of the collapse hole can be utilized to absorb the collision energy, thereby helping to reduce the collision damage to pedestrians and improving the pedestrian protection performance of the front engine compartment cover, and at the same time having a very good use effect.

[0018] In addition, the location of the collapse holes on the side walls can facilitate the collapse and energy absorption of the front bonnet inner panel during a collision, thereby improving the energy absorption effect. By limiting the distance between the side wall and the front bonnet outer panel, the front bonnet panel can have appropriate strength while setting the collapse holes, which helps to ensure the overall performance of the front bonnet. Limiting the draft angle of the side wall can facilitate the forming of the side wall, and can also make the stiffness of the side wall position appropriate to ensure pedestrian protection performance. Moreover, the rounded corners between the top wall and the side wall, and between the side wall and the bottom wall, can facilitate the stamping forming of the side structure of the front bonnet inner panel.

[0019] Secondly, the setting of the fillet radius of the first fillet and the second fillet can prevent cracking during the stamping of the front bonnet inner panel, ensuring the forming performance of the front bonnet inner panel. Both ends of the length direction of each shrinkage hole penetrate the first fillet and the second fillet on the same side, which is conducive to forming the shrinkage hole by positive punching, and only three stations are used to prepare the front bonnet inner panel, which helps to reduce the number of molds, reduce mold debugging time, and reduce the cost of cover development.

[0020] In addition, the length direction of the collapse hole is perpendicular to the first fillet and the second fillet at the position, which can ensure the structural strength of the front bonnet inner plate while improving the energy absorption effect of the collapse hole. The weight reduction hole and the inner plate reinforcement bracket set in the middle of the front bonnet inner plate are conducive to the lightweight of the front bonnet, and can also ensure the structural strength of the front bonnet, avoiding pedestrians from contacting the power engine and other structures in the cabin in the event of a collision and causing injuries. The inner plate reinforcement bracket adopts an intermediate bracket and a side bracket including a plurality of cross-connected support arms, which has a simple structure and is easy to design and form.

[0021] Another object of the present invention is to provide a vehicle, wherein the vehicle is provided with the front engine compartment cover as described above.

[0022] The vehicle described in the utility model can improve the pedestrian protection performance of the front engine cover by adopting the above-mentioned front engine cover, thereby improving the pedestrian protection performance of the vehicle and helping to improve the refined perception of the entire vehicle.

[0036] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0037] Embodiment 1

[0038] This embodiment relates to a front cabin cover, which has an overall structure such as Figure 1 and Figure 2 As shown, the front engine cover comprises a front engine cover inner plate 1 and a front engine cover outer plate 2 which are buckled and connected together. The front engine cover inner plate 1 has collapse holes 101 on both sides of the left and right sides of the front part, and the collapse holes 101 on each side are arranged close to the headlight on the same side, and the collapse holes 101 on each side are arranged in a plurality of intervals from front to back along the edge of the front engine cover inner plate 1.

[0039] At this time, as set above, by arranging multiple collapse holes 101 on both the left and right sides of the front part of the front bonnet inner panel 1, and the collapse holes 101 on each side are arranged close to the headlights on the same side, that is, the collapse holes 101 are arranged at the parts of the front bonnet inner panel that are easy for pedestrians to collide and contact. Therefore, when a collision occurs, the collapse deformation at the location of the collapse holes 101 can be used to absorb the collision energy, thereby helping to reduce the collision damage to pedestrians and improving the pedestrian protection performance of the front bonnet.

[0040] Based on the above overall introduction, specifically, as a preferred implementation, Figure 2 Combined with Figures 3 to 6 As shown, in this embodiment, both the left and right sides of the front bonnet inner panel 1 have a top wall 11 located at the edge, a side wall 12 connected to the inner side of the top wall 11, and a bottom wall 13 connected to the inner side of the side wall 12. Along the direction pointing to the bottom wall 13 on the same side, the side walls 12 on each side are arranged inwardly, and the above-mentioned collapse holes 101 on each side are located on the side wall 12 on the same side. At this time, arranging the collapse holes 101 on the side walls 12 can facilitate the collapse energy absorption of the front bonnet inner panel 1 during a collision, thereby improving the energy absorption effect.

[0041] It should be noted that the so-called inside and outside here specifically refer to the left and right sides of the front bonnet inner panel 1 close to the outside of the vehicle as the "outside" and the side close to the front engine compartment as the "inside" in the left and right directions of the vehicle.

[0042] See also Figures 2 to 6 As shown, in this embodiment, the top wall 11, the side wall 12 and the bottom wall 13 on the left and right sides are connected to form a roughly Z-shape or S-shape. The top wall 11 is used to be connected with the edge of the front nacelle cover outer panel 2. The bottom wall 13 constitutes the bottom end surface of the entire front nacelle cover, and the bottom wall 13 also serves as the layout surface of the front nacelle cover hinge and the front nacelle cover lock hook 3.

[0043] Moreover, first brackets are usually provided at both left and right ends of the rear portion of the front bonnet inner panel 1 for arranging hinges, wherein the hinge mounting position 4 is specifically as follows: Figure 2 At the same time, a second bracket is also provided at the front of the front bonnet inner plate 1 for arranging the locking hook 3, so that the front bonnet is connected to the cabin assembly through the hinge and the locking hook 3.

[0044] On the basis that the collapse holes 101 on each side are arranged on the side wall 12 on the same side, as a preferred embodiment, combined with Figure 2 and Figure 3As shown, the distance h between the side wall 12 on each side and the front bonnet outer panel 2 in the vertical direction of the vehicle is within 35 mm. By limiting the distance h between the side wall 12 and the front bonnet outer panel 2, the front bonnet can have a suitable strength while setting the collapse hole 101, which helps to ensure the overall performance of the front bonnet. It is also worth noting here that the smaller the distance h between the side wall 12 and the front bonnet outer panel 2, the better the safety performance and the better the formability.

[0045] Also as a preferred embodiment, see Figures 5 and 6 As shown, the draft angle θ of each side wall 12 is above 60°. At this time, the restriction on the draft angle θ of the side wall 12 can facilitate the molding of the side wall 12, and can also make the rigidity of the side wall 12 position appropriate, so as to ensure the pedestrian protection performance. In specific implementation, the draft angle θ of each side wall 12 can be set to 60°, 65°, 70°, 75°, 80° or 85°, for example.

[0046] At the same time, each side top wall 11 is connected to the side wall 12 through the first fillet 10, and each side side wall 12 is connected to the bottom wall 13 through the second fillet 20. In this way, it can facilitate the stamping and forming of the side structure of the front bonnet inner panel 1. And as a preference, the fillet radius R1 of the first fillet 10 is greater than 6 mm, and the fillet radius R2 of the second fillet 20 is greater than 12 mm. In this way, by setting the fillet radius of the first fillet 10 and the second fillet 20, cracking problems can be prevented during the stamping and forming of the front bonnet inner panel 1, thereby ensuring the forming performance of the front bonnet inner panel 1.

[0047] It should be noted that, in addition to setting the fillet radius R1 of the first fillet 10 to be greater than 6 mm and setting the fillet radius R2 of the second fillet 20 to be greater than 12 mm, the fillet radius R1 of the first fillet 10 may also be limited, and of course, the fillet radius R2 of the second fillet 20 may also be limited.

[0048] See also Figure 4 and Figure 5 As shown, in this embodiment, as a preferred implementation, each side collapse hole 101 is a long hole arranged in the front-to-back direction of the vehicle, and both ends of the length direction of each side collapse hole 101 are arranged through the first fillet 10 and the second fillet 20 on the same side. This can facilitate the formation of the collapse hole 101 by forward punching, and can realize the preparation of the front engine cover inner plate 1 by only three stations, which helps to reduce the number of molds, reduce the mold debugging time, and reduce the cover development cost.

[0049] Moreover, in the present embodiment, the length direction of each collapse hole 101 is perpendicular to the first fillet 10 and the second fillet 20 at the location, so that the energy absorption effect of the collapse hole can be improved while ensuring the structural strength of the front bonnet inner panel.

[0050] In specific implementation, each collapse hole 101 is processed and formed by a forward punching method. In specific processing, the angle position of the front bonnet inner panel 1 is adjusted based on the vehicle coordinate system, so that the front bonnet inner panel 1 does not rotate in the X direction, that is, rotates 0°, rotates in the Y direction by -8° to -15°, preferably -13°, and rotates in the Z direction by 180°, and the front bonnet inner panel 1 is positioned through the positioning hole, and the collapse hole 101 is formed by a forward punching method at this angle position.

[0051] It can be understood here that when each collapse hole 101 is formed by positive punching, the reference position of the front engine cover inner panel can be set accordingly according to its specific structure to ensure that each collapse hole 101 can be formed by positive punching.

[0052] In addition, in this embodiment, the review Figure 2 and Figure 4 As shown, a weight-reducing hole 30 is also formed in the middle of the front bonnet inner panel 1, and an inner panel reinforcement bracket 102 is arranged in the weight-reducing hole 30, and the inner panel reinforcement bracket 102 divides the weight-reducing hole 30 into multiple areas. At this time, the weight-reducing hole 30 and the inner panel reinforcement bracket 102 arranged in the middle of the front bonnet inner panel 1 are conducive to the lightweight of the front bonnet, and can also ensure the structural strength of the front bonnet, and can prevent pedestrians from contacting the power engine and other structures in the cabin and causing injuries in the event of a collision.

[0053] Still viewing Figure 2 and Figure 4 As shown, the inner plate reinforcement bracket 102, as a preferred embodiment, includes an intermediate bracket 111 located in the middle of the weight-reducing hole 30 in the left and right directions, and side brackets 112 arranged on both the left and right sides of the intermediate bracket 111. The intermediate bracket 111 is in a long strip structure and extends along the front-rear direction of the vehicle, while the side brackets 112 on both sides include a plurality of cross-connected arms, and preferably, they are all in an "X" shape. Such an arrangement makes the inner plate reinforcement bracket 102 relatively simple in structure and easy to design and shape.

[0054] The front bonnet of the present embodiment is provided with a collapse hole 101 at a position of the front bonnet inner panel 1 which is easily contacted with pedestrians. Thus, when a collision occurs, the collapse deformation at the location of the collapse hole 101 can be used to absorb the collision energy, thereby helping to reduce collision damage to pedestrians, and can improve the pedestrian protection performance of the front bonnet, and has a very good use effect.
