[0027] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0028] Below, reference is made to Figures 1-4 Describe the inner hood panel 1 of the engine according to the embodiments of the present utility model.

[0029] As Figure 1 shown, the inner hood panel 1 of the engine according to the embodiments of the present utility model includes: an inner panel main body 10 and a hinge reinforcement member 20. The inner panel main body 10 is the main part of the inner hood panel 1 and can mainly be used to install and set other components. The hinge reinforcement member 20 mainly plays a role in strengthening the inner panel main body 10, can strengthen the structure of the inner panel main body 10, and can also prevent the inner hood panel 1 from rebounding. Among them, two hinge reinforcement members 20 can be provided.

[0030] As Figure 1 and as Figure 2 shown, a hinge mounting part 100 is provided on the inner panel main body 10, and the hinge reinforcement member 20 is arranged on the hinge mounting part 100. The hinge mounting part 100 mainly plays a mounting role and can be used to mount the hinge reinforcement member 20. The hinge reinforcement member 20 is arranged on the hinge mounting part 100. At this time, it is convenient for the installation and setting of the hinge reinforcement member 20. In addition, the hinge reinforcement member 20 and the inner panel main body 10 form an integral body, which is convenient for the installation and setting of the inner hood panel 1. Among them, two hinge mounting parts 100 can be provided.

[0031] As Figure 1 and Figure 3As shown in the figure, a first main rib 200 and a first branch rib 201 are provided on the hinge reinforcement 20. One end of the first branch rib 201 is connected to the first main rib 200, and the other end of the first branch rib 201 extends towards the edge of the hinge reinforcement 20. Both the first main rib 200 and the first branch rib 201 are components of the hinge reinforcement 20. The first main rib 200 can enhance the strength and stiffness of the hinge reinforcement 20, and can improve the physical properties of the hinge reinforcement 20. The first branch rib 201 mainly can disperse the force application direction of the hinge reinforcement 20. One end of the first branch rib 201 is connected to the first main rib 200. At this time, the first branch rib 201 and the first main rib 200 form a whole, which is convenient for the installation and setting of the hinge reinforcement 20. The other end of the first branch rib 201 extends towards the edge of the hinge reinforcement 20, that is, the first branch rib 201 penetrates the internal area between the first main rib 200 and the edge of the reinforcement 20. In this way, a distribution form similar to the veins of a leaf can be formed. Specifically, when the hinge reinforcement 20 is stressed, most of the forces applied to the hinge reinforcement 20 will be concentrated on the first main rib 200, and the first main rib 200 can disperse the forces through the first branch rib 201. In this way, the stress at the first main rib 200 can be reduced, so as to ensure that the overall stress of the hinge reinforcement 20 is uniform.

[0032] Therefore, the hinge reinforcement 20 is designed with a first main rib 200 and a first branch rib 201 in imitation of the vein distribution form of natural leaves. After the hinge reinforcement 20 is stressed, the first main rib 200 will disperse the forces through the first branch rib 201, which can ensure that the overall stress of the hinge reinforcement 20 is uniform, and has an effect on improving the local stiffness deficiency of the hinge installation part 100 and the fatigue durability of the hinge reinforcement 20, and can play an effective strengthening role.

[0033] Specifically, as Figure 3 shown, there are at least two first branch ribs 201, and at least two first branch ribs 201 are respectively connected to both sides of the first main rib 200. That is to say, at least one first branch rib 201 is provided on each side of the first main rib 200. First of all, such a setting can make the structure of the hinge reinforcement 20 more integral. In addition, after the hinge reinforcement 20 is stressed, the forces on the first main rib 200 can be dispersed to the positions on both sides, and then the forces are dispersed through the first branch ribs 201 on both sides. In this way, the force dispersion path can be increased, so as to better reduce the stress at the first main rib 200 and ensure that the overall stress of the hinge reinforcement 20 is uniform, and has an effect on improving the local stiffness deficiency of the hinge installation part 100 and the fatigue durability of the hinge reinforcement 20, and can play an effective strengthening role.

[0034] Among them, as Figure 1 and Figure 2As shown, an annular beam 101 and reinforcing ribs 102 are further provided on the inner panel main body 10. The hinge mounting portion 100 is disposed on the annular beam 101. An installation hole 103 is formed inside the annular beam 101, and the reinforcing rib 102 is connected to the installation hole 103. The annular beam 101 is an integral part of the inner panel main body 10 and is mainly used for installing other components. The reinforcing rib 102 can mainly enhance the strength and stiffness of the inner panel main body 10, can take into account the load transfer of the inner panel main body 10 and absorb impact energy, and can protect pedestrian safety.

[0035] It should be noted that the annular beam 101 has an annular structure, and its structure is relatively firm and stable. For example, features such as positioning holes, buffer block mounting holes, lock mounting points, and hinge mounting surfaces are all arranged on the annular beam 101. The hinge mounting portion 100 is disposed on the annular beam 101, which can improve the firmness and stability of the structure of the hinge mounting portion 100 and will be more reliable when installing the hinge reinforcement 20. In addition, it can also avoid the problem of large deformation of the engine hood caused by insufficient stiffness of the hinge mounting portion 100 and interference with surrounding components such as fenders, ventilation covers, hinge shields, and wiper output shafts.

[0036] An installation hole 103 is formed inside the annular beam 101, and the reinforcing rib 102 is connected to the installation hole 103, which is convenient for setting. The reinforcing rib 102 can be formed into a strengthening area to enhance the internal structural strength of the inner panel main body 10. At the same time, since the reinforcing rib 102 is located in the installation hole 103, the reinforcing rib 102 and the installation hole 103 can jointly define a hollowed-out weakened area, and the hollowed-out weakened area can take into account the load transfer of the inner panel main body 10 and absorb impact energy, thereby playing a role in protecting pedestrian safety.

[0037] In addition, such as Figure 1 and Figure 2As shown in the figure, the reinforcing rib 102 includes: a second main rib 104 and second branch ribs 105. The two ends of the second main rib 104 are respectively connected to the inner side of the annular beam 101. One end of the second branch rib 105 is connected to the second main rib 104, and the other end of the second branch rib 105 is connected to the inner side of the annular beam 101. Both the second main rib 104 and the second branch ribs 105 are components of the reinforcing rib 102. The second main rib 104 can enhance the strength and stiffness of the inner plate main body 10 and improve the physical properties of the inner plate main body 10. The second branch ribs 105 mainly can disperse the force application direction of the inner plate main body 10. The two ends of the second main rib 104 are respectively connected to the inner side of the annular beam 101. In other words, the second main rib 104 penetrates through the two ends of the annular beam 101. The second branch ribs 105 on both sides of the second main rib 104 extend to the inner side edges of the annular beam. In this way, the distribution form of the bionic leaf ribs can also be formed. Specifically, when a force is applied to the inner side position of the inner plate main body 10, most of the forces received by the reinforcing rib 102 will be concentrated on the second main rib 104, and the second main rib 104 can disperse the force through the second branch ribs 105. This can reduce the force received at the second main rib 104, thereby ensuring the uniform force application of the entire reinforcing rib 102, and further better taking into account the load transfer of the inner plate main body 10, absorbing impact energy, and protecting pedestrian safety.

[0038] Of course, as Figure 1 and Figure 2 shown, there are at least two second branch ribs 105. The at least two second branch ribs 105 are respectively connected to both sides of the second main rib 104. That is to say, at least one second branch rib 105 is provided on each side of the second main rib 104. First of all, such a setting can make the structure of the reinforcing rib 102 more integral. In addition, after the reinforcing rib 102 is stressed, the force on the second main rib 104 is dispersed to the positions on both sides, and then the force is dispersed through the second branch ribs 105 on both sides. This can increase the force dispersion path, thereby better reducing the force received at the second main rib 104, ensuring the uniform force application of the entire reinforcing rib 102, and playing an effective strengthening role.

[0039] Furthermore, as Figure 1 and Figure 2As shown in the figure, the annular beam 101 includes: a first beam segment 106, a second beam segment 107, a third beam segment 108, and a fourth beam segment 109. The first beam segment 106, the second beam segment 107, the third beam segment 108, and the fourth beam segment 109 are connected end to end in sequence. The hinge mounting portions 100 are provided at the connection between the first beam segment 106 and the second beam segment 107, and at the connection between the third beam segment 108 and the second beam segment 107. That is to say, the first beam segment 106, the second beam segment 107, the third beam segment 108, and the fourth beam segment 109 are all components of the annular beam 101. The first beam segment 106, the second beam segment 107, the third beam segment 108, and the fourth beam segment 109 form the annular beam 101 by being connected end to end in sequence. There are two hinge mounting portions 100 provided. The two hinge mounting portions 100 are respectively provided at the connection between the first beam segment 106 and the second beam segment 107, and at the connection between the third beam segment 108 and the second beam segment 107. In this way, the two hinge mounting portions 100 are located at relatively symmetrical positions, making the structure of the inner panel 1 of the engine hood more integral. Moreover, the two hinge mounting portions 100 will be located at the corners of the annular beam 101 and will not affect the arrangement of other structures on the annular beam 101.

[0040] In addition, as Figure 1 , Figure 2 and 4 shown, the cross-sectional structure at the connection between the first beam segment 106 and the fourth beam segment 109, and at the connection between the third beam segment 108 and the fourth beam segment 109 is an arc structure. It should be noted that at the connection between the first beam segment 106 and the fourth beam segment 109, and at the connection between the third beam segment 108 and the fourth beam segment 109, there will be a problem of stamping springback. By constructing the cross-sectional structures at these two positions as arc structures, the arc structure can specifically be a drum-shaped surface structure. The arc structure is relatively smooth, which can enhance the overall spatial aesthetic feeling of the inner panel 1 of the engine hood and can also enhance the visual extensibility. Structurally, the arc structure is not easily deformed, which is beneficial to solving the springback problem after stamping of the inner panel 1 of the engine hood.

[0041] It should be noted that, as Figure 1 , Figure 2 and Figure 4 shown, the cross-sectional structure of the inner panel main body 10 is a stepped structure. Specifically, the outer layer of the inner panel main body 10 is set as the annular beam 101, and the inner layer is set as the reinforcing rib 102. The reinforcing rib 102 is connected to the annular beam 101 through the mounting holes 103 inside the annular beam 101. In this way, the cross-section of the inner panel main body 10 will be constructed as a stepped layered structure, and the stepped layered structure can enhance the overall structural strength of the inner panel main body 10, making it not easily damaged during the installation and setting of the inner panel main body 10, thereby improving the overall service life of the inner panel 1 of the engine hood.
