[0021] The reinforcing plate body 1 is a one-character structure extending along the left-right direction of the vehicle. In this embodiment, the reinforcing plate body 1 extends along the left-right direction as a whole and has a curvature to match the engine hood structure of the vehicle. The reinforcing plate body 1 is designed as a one-character structure to meet the anti-denting requirements within a range of 150 mm on both sides of the reinforcing plate, which simplifies the structural design of the reinforcing plate. The engine hood reinforcing plate is simplified from a complex grid structure to a one-character structure, and the structure of the reinforcing plate is more simple, which is conducive to reducing the design and manufacturing process difficulty and improving the design quality. In this embodiment, the weight of the simplified reinforcing plate body 1 is reduced from 0.472 kg to 0.135 kg, and the weight reduction ratio is 60%. The cost can be reduced under the condition of meeting the performance; in addition, the simplified structure of the part can also save the amount of shock-absorbing sealant.

[0022] The side of the reinforcing plate body 1 facing the inner panel 8 of the engine hood is defined as the inner side when assembled, and the side facing the rear of the vehicle is defined as the rear side. The reinforcing plate body 1 is provided with a reinforcing rib groove 3 recessed toward the inner side thereof, and the reinforcing rib groove 3 extends along the length direction of the reinforcing plate body 1. The reinforcing rib groove 3 can improve the rigidity of the reinforcing plate body 1, thereby improving the compression deformation resistance of the outer panel 7 of the engine hood.

[0023] The reinforcing rib groove 3 is used to accommodate the sealant 9, and after the reinforcing plate body 1 is fixed to the inner panel 8 of the engine hood through the supporting leg 2, the outer panel 7 of the engine hood is fixedly connected through the shock-absorbing sealant, thereby playing a supporting and shock-absorbing role. After the reinforcing rib groove 3 accommodates the sealant 9, it can be used as a glue groove, which increases the contact area between the shock-absorbing sealant and the reinforcing plate body 1, improves the fixing strength and the shock-absorbing effect. In this embodiment, the surface of the reinforcing plate body 1 facing the outer panel 7 is a sealant 9 plane, the width of the sealant 9 plane is 20 mm, and the gap between the sealant 9 plane and the outer panel 7 of the engine hood is a sealant 9 gap, which is 3 mm, i.e. the thickness of the shock-absorbing sealant is 3 mm.

[0024] The plurality of support legs 2 are distributed along the length direction of the reinforcing plate body 1, and the support legs 2 are used to be fixedly connected with the inner panel 8 of the engine hood, and the support legs 2 support the reinforcing plate body 1. In the embodiment, the support legs 2 are welded and fixed with the inner panel 8 of the engine hood, and the support legs 2 are six in total, four of which are located at the rear side of the reinforcing plate body 1, and the other two are located at the front side of the reinforcing plate body 1. The support legs 2 are staggered in the length direction of the reinforcing plate body 1, so as to increase the stability of the support.

[0025] The reinforcing plate body 1 of the engine hood reinforcing plate is in a linear structure extending along the left-right direction of the vehicle. When the engine hood reinforcing plate is installed, the reinforcing plate body 1 can be arranged within a set distance from the front end of the engine hood to the inner panel 8 of the engine hood, so as to meet the requirement of the anti-denting of the target range around the reinforcing plate body 1. The support legs 2 are fixed with the inner panel 8 of the engine hood, and the reinforcing rib groove 3 is coated with glue 9 to be fixedly connected with the outer panel 7 of the engine hood. The reinforcing plate is simplified from a network structure to a linear structure, the part structure is more simple, the blanking size and weight of the reinforcing plate body 1 are reduced, the material utilization rate is improved, the part cost and manufacturing cost are reduced, the design and manufacturing process difficulty is reduced, and the manufacturing quality is improved.

[0026] Preferably, the reinforcing plate body 1 is further provided with a flange 4 extending towards the inner side of the reinforcing plate body 1, and the flange 4 and the reinforcing plate body 1 form an inner cavity.

[0027] The flange 4 is arranged at the edge position of the reinforcing plate body 1, and the flange 4 and the reinforcing plate body 1 form an inner cavity, so that the entire reinforcing plate is in a box-shaped structure, which is beneficial to improve the rigidity of the reinforcing plate and the compression deformation resistance of the outer panel 7 of the engine hood.

[0028] Since the flange 4 extends towards the inner side of the reinforcing plate body 1, after the reinforcing plate body 1 is welded and fixed with the inner panel 8 of the engine hood, the inner cavity faces the inner panel 8 of the engine hood, and the reinforcing rib groove 3 is recessed and embedded in the inner cavity. The inner cavity provides a recessed space for the reinforcing rib groove 3, so as to avoid interference with the inner panel 8 of the engine hood.

[0029] Preferably, the flange 4 has an exhaust port 5 communicating with the inner cavity.

[0030] The inner cavity formed by the flange 4 and the reinforcing plate body 1 faces the inner panel 8 and forms a relatively closed box-shaped structure with the inner panel 8, which is easy to cause gas accumulation. During painting, the gas will affect the painting quality, resulting in insufficient paint film thickness and poor corrosion resistance. After the exhaust port 5 is arranged on the flange 4, the gas is discharged from the inner cavity during painting, so as to ensure uniform painting thickness.

[0031] Preferably, the flange 4 has an intermittent portion around the edge of the reinforcing plate body 1, the intermittent portion is located at the rear side of the reinforcing plate body 1, and the intermittent portion forms the exhaust port 5.

[0032] The flange 4 is arranged around the edge of the reinforcement plate body 1, after the discontinuous part is arranged, the reinforcement plate body 1 is welded with the inner plate 8, the position of the discontinuous part naturally forms the exhaust port 5, without additional processing on the flange 4, the forming mode of the exhaust port 5 is simplified.

[0033] In the embodiment, the flange 4 is inclined to extend backward at the discontinuous part, and the flange 4 is smoothly connected as a whole, stress is reduced, and the flange 4 has a gathering and guiding effect on exhaust.

[0034] Preferably, the height of the flange 4 ranges from 2 to 4 mm.

[0035] If the height of the flange 4 is too high, the flange 4 will interfere with the inner plate 8, and if the height of the flange 4 is too low, the flange 4 cannot play a role in improving the stiffness of the reinforcement plate body 1, and the height is set to be 2-4 mm, which can effectively utilize the space between the outer plate 7 and the inner plate 8 of the engine cover while improving the stiffness. In the embodiment, the height of the flange 4 is 3 mm.

[0036] Preferably, the depth of the reinforcing rib groove 3 ranges from 2 to 4 mm.

[0037] If the depth of the reinforcing rib groove 3 is too small, the stiffness is not improved, and if the depth of the reinforcing rib groove 3 is too small, the reinforcing rib groove 3 will interfere with the inner plate 8 of the engine cover, the depth of the reinforcing rib groove 3 is the same as the depth of the flange 4, which can effectively utilize the space of the inner cavity surrounded by the flange 4 while improving the stiffness of the reinforcement plate body 1, and avoid interference with the inner plate 8 of the engine cover.

[0038] Preferably, the reinforcement plate body 1 is further provided with a positioning hole 6, and the positioning hole 6 is located at both ends of the length direction of the reinforcement plate body 1.

[0039] The positioning hole 6 is used for positioning the engine cover reinforcement plate during installation, and the two ends of the length direction of the reinforcement plate body 1 are the maximum outer contour of the reinforcement plate body 1, and the positioning effect of the positioning hole 6 arranged at the two ends is better.

[0040] The utility model also provides an optimal embodiment of an engine cover assembly, which comprises an outer plate 7, an inner plate 8 and a reinforcement plate, and the specific structure of the reinforcement plate is the same as that of the engine cover reinforcement plate in any of the above embodiments, and is not repeated here.
