[0035] Next, in conjunction with Figures 1 - 3 The inner panel 10 of the engine hood, the engine hood assembly and the vehicle according to the embodiments of the present utility model will be described in detail.

[0036] Referring to Figure 1 and Figure 2As shown in the figure, the inner panel 10 of the engine hood according to the embodiment of the present utility model includes an inner panel body 1, a transverse reinforcing rib 2, and a plurality of radial reinforcing ribs 3. The transverse reinforcing rib 2 is connected to the inner panel body 1 and extends along the width direction of the inner panel body 1 to the edges on both sides of the inner panel body 1. Each radial reinforcing rib 3 is connected to the inner panel body 1, and the plurality of radial reinforcing ribs 3 intersect at the center 21 of the transverse reinforcing rib 2, and the plurality of radial reinforcing ribs 3 extend radially from the center 21 of the transverse reinforcing rib 2 to the edge of the inner panel body 1. The transverse reinforcing rib 2 and the plurality of radial reinforcing ribs 3 can jointly improve the structural strength of the inner panel 10 of the engine hood, improve the bending resistance and torsional stiffness of the inner panel 10 of the engine hood, improve the stability of the inner panel 10 of the engine hood, and are beneficial to improving the NVH (Noise, Vibration, Harshness) mode of the inner panel 10 of the engine hood. Among them, the center 21 of the transverse reinforcing rib 2 can be the center point of the transverse reinforcing rib 2 or the middle section area of the transverse reinforcing rib 2.

[0037] It can be understood that the width direction of the inner panel body 1 is Figure 1 and Figure 2 the left-right direction in the figure. The transverse reinforcing rib 2 extends along the width direction of the inner panel body 1 to the edges on both sides of the inner panel body 1. The transverse reinforcing rib 2 can strengthen the structural strength of the inner panel 10 of the engine hood in the width direction of the inner panel body 1. The plurality of radial reinforcing ribs 3 extend radially from the center 21 of the transverse reinforcing rib 2 to the edge of the inner panel body 1. The plurality of radial reinforcing ribs 3 can increase the force transmission path. The connection of the plurality of radial reinforcing ribs 3 to the center 21 of the transverse reinforcing rib 2 can form a plurality of continuous force transmission paths. When the inner panel 10 of the engine hood is stressed, the force can be transmitted through the transverse reinforcing rib 2 and the plurality of radial reinforcing ribs 3 and evenly distributed on the inner panel 10 of the engine hood, which is beneficial to reducing the risk of local concentrated stress on the inner panel 10 of the engine hood, thereby reducing the risk of cracking and failure of the inner panel 10 of the engine hood and improving the durability of the inner panel 10 of the engine hood.

[0038] For the inner panel 10 of the engine hood according to the embodiment of the present utility model, the transverse reinforcing rib 2 extends along the width direction of the inner panel body 1 to the edges on both sides of the inner panel body 1. The plurality of radial reinforcing ribs 3 extend radially from the center 21 of the transverse reinforcing rib 2 to the edge of the inner panel body 1. The transverse reinforcing rib 2 and the plurality of radial reinforcing ribs 3 can jointly improve the overall structural strength of the inner panel 10 of the engine hood, improve the bending resistance and torsional stiffness of the inner panel 10 of the engine hood, reduce the risk of cracking and failure of the inner panel 10 of the engine hood, and improve the durability of the inner panel 10 of the engine hood.

[0039] In some embodiments of the present utility model, referring to Figure 1 and Figure 2As shown, each radial reinforcing rib 3 has another radial reinforcing rib 3 that is centrosymmetric with respect to the center 21 of the transverse reinforcing rib 2. Two radial reinforcing ribs 3 that are centrosymmetric with respect to the center 21 of the transverse reinforcing rib 2 can form a linear reinforcing rib, so that the force transmission path is a straight line, facilitating the transmission of force.

[0040] Referring to Figure 1 As shown, the multiple radial reinforcing ribs 3 can be respectively the first radial reinforcing rib 3a, the second radial reinforcing rib 3b, the third radial reinforcing rib 3c, and the fourth radial reinforcing rib 3d. The first radial reinforcing rib 3a and the third radial reinforcing rib 3c are centrosymmetric with respect to the center 21 of the transverse reinforcing rib 2, and the first radial reinforcing rib 3a and the third radial reinforcing rib 3c can form a linear reinforcing rib. The second radial reinforcing rib 3b and the fourth radial reinforcing rib 3d are centrosymmetric with respect to the center 21 of the transverse reinforcing rib 2, and the second radial reinforcing rib 3b and the fourth radial reinforcing rib 3d can form a linear reinforcing rib.

[0041] In some embodiments of the present utility model, referring to Figure 1 and Figure 2 As shown, each radial reinforcing rib 3 has another radial reinforcing rib 3 that is axially symmetric with respect to the transverse reinforcing rib 2. For example, the first radial reinforcing rib 3a and the second radial reinforcing rib 3b are axially symmetric with respect to the transverse reinforcing rib 2, and the third radial reinforcing rib 3c and the fourth radial reinforcing rib 3d are axially symmetric with respect to the transverse reinforcing rib 2. Moreover, the first radial reinforcing rib 3a and the third radial reinforcing rib 3c are centrosymmetric with respect to the center 21 of the transverse reinforcing rib 2 and form a linear reinforcing rib extending to the edges on both sides of the inner panel body 1. The second radial reinforcing rib 3b and the fourth radial reinforcing rib 3d are centrosymmetric with respect to the center 21 of the transverse reinforcing rib 2 and form a linear reinforcing rib extending to the edges on both sides of the inner panel body 1. The two linear reinforcing ribs can symmetrically strengthen the structural strength of the inner engine hood panel 10 in the width direction on both sides of the transverse reinforcing rib 2, which is beneficial to improving the consistency of the structural strength of the inner engine hood panel 10 on both sides of the transverse reinforcing rib 2.

[0042] In some embodiments of the present utility model, referring to Figure 1 and Figure 2As shown, a plurality of first weakening holes 112 are formed between two adjacent radial reinforcing ribs 3 on the inner panel body 1. A first strip plate 113 and a second strip plate 114 which are connected at an angle are formed in the area of the plurality of first weakening holes 112 on the inner panel body 1, and the first strip plate 113 and the second strip plate 114 are respectively connected to different radial reinforcing ribs 3. The first strip plate 113 and the second strip plate 114 can increase the force transmission path. When the inner panel 10 of the engine hood is in normal use, the force on the inner panel body 1 at the first weakening holes 112 can be transmitted to the two connected radial reinforcing ribs 3 respectively through the first strip plate 113 and the second strip plate 114, which is beneficial to reducing the risk of deformation of the inner panel body 1 at the first weakening holes 112.

[0043] It can be understood that a plurality of first weakening holes 112 are formed on the inner panel body 1, which can improve the crash energy absorption effect of the inner panel body 1. When a vehicle collides with a pedestrian, the inner panel body 1 can collapse and absorb energy at the first weakening holes 112 to reduce the injury to the pedestrian and increase the survival space of the hit pedestrian. The first strip plate 113 and the second strip plate 114 can prevent a relatively large hole from being formed between two adjacent radial reinforcing ribs 3 on the inner panel body 1. The first strip plate 113 and the second strip plate 114 can appropriately strengthen the structural strength of the inner panel body 1. When the inner panel 10 of the engine hood is in normal use, the risk of cracking and failure of the inner panel body 1 can be reduced, and the durability of the inner panel body 1 can be improved.

[0044] Refer to Figure 1 and Figure 2 As shown, three first weakening holes 112 are formed between two adjacent radial reinforcing ribs 3, two of the first weakening holes 112 are triangular holes, and the other first weakening hole 112 is a rhombic hole. The first strip plate 113 and the second strip plate 114 form a V-shaped structure, and the angle between the first strip plate 113 and the second strip plate 114 is opposite to the angle between two adjacent radial reinforcing ribs 3. When a vehicle collides with a pedestrian, the inner panel body 1 can collapse and absorb energy at the first weakening holes 112. At this time, the angle between the first strip plate 113 and the second strip plate 114 can gradually increase to facilitate the collapse of the inner panel body 1 in the front-rear direction, thereby being beneficial to reducing the injury to the pedestrian.

[0045] Refer to Figure 1 and Figure 2 As shown, the inner panel body 1 has the first strip plate 113, the second strip plate 114 and a plurality of first weakening holes 112 on both the front and rear sides of the transverse reinforcing rib 2, which can, while ensuring the crash energy absorption effect of the inner panel body 1, appropriately strengthen the structural strength of the inner panel body 1, reduce the risk of cracking and failure of the inner panel body 1, and improve the durability of the inner panel body 1.

[0046] In some embodiments of the present utility model, the number of the radiation reinforcing ribs 3 is N, which satisfies the relational expression: N≥4. For example, the number of the radiation reinforcing ribs 3 can be four, five, six, etc., which can effectively improve the structural strength of the inner panel 10 of the engine hood.

[0047] In some embodiments of the present utility model, with reference to Figure 3 As shown, the radiation reinforcing rib 3 includes: a first sub-reinforcing rib 31, a second sub-reinforcing rib 32, and a plurality of connecting sub-reinforcing ribs 33. The first sub-reinforcing rib 31 and the second sub-reinforcing rib 32 are arranged in parallel, and the plurality of connecting sub-reinforcing ribs 33 are arranged at intervals, and each connecting sub-reinforcing rib 33 is connected between the first sub-reinforcing rib 31 and the second sub-reinforcing rib 32, which is beneficial to further improve the structural strength of the inner panel 10 of the engine hood.

[0048] It can be understood that the connecting sub-reinforcing rib 33 is connected between the first sub-reinforcing rib 31 and the second sub-reinforcing rib 32. The connecting sub-reinforcing rib 33 can support the first sub-reinforcing rib 31 and the second sub-reinforcing rib 32 to improve the structural strength of the radiation reinforcing rib 3, thereby being beneficial to improving the structural strength of the inner panel 10 of the engine hood. In addition, the connecting sub-reinforcing rib 33 can increase the force transmission path, which is beneficial to the uniform distribution of force in the inner panel 10 of the engine hood and reduces the risk of local deformation of the inner panel 10 of the engine hood.

[0049] In some embodiments of the present utility model, the included angle between the transverse reinforcing rib 2 and the radiation reinforcing rib 3 is α, which satisfies the relational expression: 20°≤α≤70°. For example, α can be 20°, 45°, 70°, etc., which can improve the structural strength of the inner panel 10 of the engine hood.

[0050] It can be understood that the length direction of the inner panel 10 of the engine hood is Figure 1 and Figure 2 the front-back direction in

[0051] Referring to FIGS. 1 and Figure 2 as shown, the number of the radiation stiffeners 3 is four, and the angle between the transverse stiffener 2 and the radiation stiffeners 3 is in the range of 20° to 70°. The four radiation stiffeners 3 can be respectively the first radiation stiffener 3a, the second radiation stiffener 3b, the third radiation stiffener 3c and the fourth radiation stiffener 3d. Among them, the first radiation stiffener 3a and the second radiation stiffener 3b are axially symmetric with respect to the transverse stiffener 2, the first radiation stiffener 3a and the third radiation stiffener 3c are centrosymmetric with respect to the center 21 of the transverse stiffener 2, the third radiation stiffener 3c and the fourth radiation stiffener 3d are axially symmetric with respect to the transverse stiffener 2, the second radiation stiffener 3b and the fourth radiation stiffener 3d are centrosymmetric with respect to the center 21 of the transverse stiffener 2. The transverse stiffener 2 and the 4 radiation stiffeners 3 can form a "water" shape, which can effectively improve the structural strength of the inner panel 10 of the engine hood.

[0052] In some embodiments of the present invention, referring to Figure 1 and Figure 2 as shown, the inner panel 10 of the engine hood further includes: a front stiffener 4, the front stiffener 4 is connected to the inner panel body 1, and the front stiffener 4 is formed with a grid structure to improve the structural strength of the front part of the inner panel 10 of the engine hood and improve the bending stiffness of the front part of the inner panel 10 of the engine hood. Among them, each grid of the front stiffener 4 can be triangular, quadrilateral, pentagonal, etc. The specific shape and grid density can be arranged and designed according to the torsional stiffness requirements. For example, when there is a hole structure in the front part of the inner panel 10 of the engine hood, the grid density of the front stiffener 4 can be increased at the hole structure to improve the structural strength of the inner panel 10 at the hole structure.

[0053] It can be understood that the front stiffener 4 forms a grid structure. When the inner panel body 1 is stressed, the force can be transmitted through the front stiffener 4 of the grid structure and evenly distributed at the front part of the inner panel body 1, avoiding local stress concentration, which is beneficial to reducing the risk of local deformation of the front part of the inner panel body 1.

[0054] In some embodiments of the present invention, referring to Figure 1 and Figure 2 as shown, the inner panel body 1 includes: a body part 11 and a boss part 12.

The inner panel 10 of the engine hood further includes: a hole stiffener 5, the hole stiffener 5 is arranged on the radially outer side of the buffer block mounting hole 121 and is respectively connected to the boss part 12 and the body part 11 to improve the structural strength of the boss part 12, reduce the risk of deformation of the boss part 12, and is beneficial to ensuring the position accuracy of the buffer block mounting hole 121.

[0055] Among them, the buffer block mounting hole 121 is adapted to mount a buffer block, and the buffer block is adapted to be in abutting cooperation with the vehicle body below the inner panel 10 of the engine hood. When the inner panel 10 of the engine hood is closed, the buffer block can play a role in shock absorption and buffering to reduce the impact transmitted from the inner panel 10 of the engine hood to the vehicle body, thereby facilitating reducing the risk of abnormal vibration and abnormal noise of the vehicle. The boss portion 12 is adapted to protrude downward from the inner panel 10 of the engine hood, so as to facilitate the use of a buffer block with a shorter length to be in abutting cooperation with the vehicle body, which is beneficial to saving the manufacturing cost of the buffer block.

[0056] Referring to Figure 1 、 Figure 4 and Figure 5 shown, there are four boss portions 12, two in a group. The two groups of boss portions 12 are respectively located in front of and behind the transverse reinforcing rib 2. Referring to Figure 4 shown, the boss portion 12 located in front of the transverse reinforcing rib 2 is connected with four hole reinforcing ribs 5 on the radial outer side of its buffer block mounting hole 121. The four hole reinforcing ribs 5 can form a rectangular structure reinforcing rib, which can effectively improve the structural strength of the boss portion 12. Referring to Figure 5 shown, the boss portion 12 located behind the transverse reinforcing rib 2 is connected with six hole reinforcing ribs 5 on the radial outer side of its buffer block mounting hole 121. The six hole reinforcing ribs 5 can form a "water" - shaped structure reinforcing rib, which can effectively improve the structural strength of the boss portion 12.

The rear reinforcing rib 6 is fixedly connected to the rear part of the inner panel body 1. The rear reinforcing rib 6 can be composed of a plurality of sequentially connected "C" - shaped reinforcing ribs.

[0059] In some embodiments of the present utility model, referring to Figure 2 shown, the inner panel body 1 may further include a flanging portion 13. The flanging portion 13 is connected to the outside of the main body portion 11. There is an included angle between the flanging portion 13 and the main body portion 11.

At the same time, it is also beneficial to improve the crashworthiness performance of the engine hood inner panel 10. When a vehicle collides with a pedestrian, the engine hood inner panel 10 can collapse at the second weakening hole 115 to absorb the impact of the vehicle on the pedestrian, reduce the injury to the pedestrian, and increase the survival space of the hit pedestrian. Among them, the shape of the second weakening hole 115 can be triangular, quadrilateral, pentagonal, etc.

[0061] In some embodiments of the present invention, the grid-shaped front reinforcing rib 4 is connected to the radial reinforcing rib 3, or the grid-shaped front reinforcing rib 4 is located on the extension line of the radial reinforcing rib 3. The front reinforcing rib 4 and the radial reinforcing rib 3 can transmit force to each other or indirectly transmit force through the inner panel body 1 to play a role in dispersing force, which is beneficial to avoiding local stress concentration of the inner panel body 1 and reducing the risk of local deformation of the inner panel body 1.

[0062] In some embodiments of the present invention, the engine hood inner panel 10 can be made of SMC composite material (Sheet molding compound, sheet molding compound). The SMC composite material has the advantages of light weight and high strength, which is beneficial to realizing the lightweight of the engine hood inner panel 10 and improving the structural strength of the engine hood inner panel 10.
