[0028] With the development of the automobile industry, the collision process between the vehicle and the pedestrian is paid more and more attention to the protection of the pedestrian. However, in order to achieve better protection effect, the active front cover hinge is generally used to connect between the front engine cover and the engine compartment, but the active front cover hinge has the disadvantages of high cost, complex mechanism, high maintenance cost and the like. Therefore, it is necessary to improve the structure of the front engine cover to reduce the harm to the pedestrian under the condition of meeting the structural strength, and to protect the pedestrian.

[0029] In order to solve the above technical problems, with reference to Figure 1As shown, the application provides a front engine hood inner panel, the front engine hood inner panel comprises an inner panel body 10 and a connecting rib 20, the inner panel body 10 is used for connecting the front engine, the inner panel body 10 forms a collapse hole 11; the connecting rib 20 comprises a first connecting rib 21 and a second connecting rib 22, the first connecting rib 21 is an annular connecting rib, the first connecting rib 21 is located on the side of the collapse hole 11 away from the front engine, the orthographic projection of the first connecting rib 21 on the inner panel body 10 is located in the collapse hole 11, and the second connecting rib 22 is obliquely connected to the first connecting rib 21 and the hole wall of the collapse hole 11. Thus, the collapse hole 11 is arranged on the inner panel body 10, and the connecting rib 20 can be arranged in the collapse hole 11 for connecting the outer panel. The first connecting rib 21 is located on the side of the collapse hole 11 away from the front engine, and the second connecting rib 22 is obliquely connected to the first connecting rib 21 and the hole wall of the collapse hole 11, so that the connecting rib 20 protrudes in the collapse hole 11 to the side away from the front engine. When the front engine hood inner panel collides with a pedestrian, the head of the pedestrian contacts the front engine hood inner panel, the annular connecting rib can have a hole, and if the impact position is located in the hole, the direct collision of the head with the inner panel body 10 can be reduced, thereby reducing the injury to the head of the pedestrian; if the impact position is located in the connecting rib 20, after the first connecting rib 21 and the second connecting rib 22 collide with the head, the first connecting rib 21 and the second connecting rib 22 can absorb energy and deform towards the collapse hole 11, thereby also reducing the injury to the head. In view of the above analysis, the front engine hood inner panel designed in this way plays a supporting role in the collapse hole 11 through the connecting rib 20, and can also reduce the degree of injury to the head when the front engine hood collides with the pedestrian.

[0030] In some embodiments, with reference to Figure 1 As shown, the inner panel body 10 forms a third recess 12, the third recess 12 is located on the radial outside of the collapse hole 11, and the third recess 12 is recessed to the side away from the connecting rib 20. The front engine hood inner panel is connected with the front engine hood outer panel, and the third recess 12 can increase the structural strength of the inner panel body 10, because the third recess 12 is recessed to the side away from the connecting rib 20, if the impact position is located in the third recess 12, the front engine hood outer panel can deform towards the third recess 12 after being stressed, thereby reducing the support to the hood outer panel, and further reducing the injury to the head.

[0031] In some embodiments, the size and shape of the collapse hole 11 are set according to actual needs, the size and number of the first connecting rib 21 are set according to the size and shape of the collapse hole 11, and the size and number of the second connecting rib 22 are set according to the size and shape of the collapse hole 11.

[0032] In some embodiments, with reference to Figure 2As shown, the second connecting rib 22 is provided in plurality, and the plurality of second connecting ribs 22 are arranged at the radial outer side of the first connecting rib 21. Specifically, one second connecting rib 22 is arranged on each side of the first connecting rib 21 in the first direction X1; and four second connecting ribs 22 are arranged on each side of the first connecting rib 21 in the second direction X2. Specifically, the width of the first connecting rib 21 in the first direction X1 is greater than the width in the second direction X2, and the number of the second connecting ribs 22 is 10, so that more second connecting ribs 22 are arranged in the direction with greater width, thereby being able to play a better supporting role. The interval arrangement of the second connecting rib 22 can form an interval, and when the head collides with the front engine hood inner panel, such as the collision position being located at the interval, direct collision with the connecting rib 20 and the inner panel body 10 can be avoided, so as to reduce the damage to the head.

[0033] In some embodiments, with reference to Figure 2 and Figure 3 As shown, the second connecting rib 22 includes a connecting portion 221 and a collapse portion 222, the connecting portion 221 connects the first connecting rib 21 and the collapse portion 222, the collapse portion 222 connects the hole wall of the collapse hole 11 on the side away from the connecting portion 221, and the collapse portion 222 is arranged obliquely between the connecting portion 221 and the hole wall of the collapse hole 11. The connecting angle of the connecting portion 221 with the first connecting rib 21 is arranged according to actual needs, and specifically, the first connecting portion 221 and the first connecting rib 21 can be arranged on the same plane. The collapse portion 222 can be deformed when the collision occurs, so as to make the first connecting rib 21 recessed toward the side of the front engine compartment, thereby reducing the damage to the head.

[0034] In some embodiments, with reference to Figure 2 and Figure 3 As shown, the collapse portion 222 includes a first collapse portion 2221, a second collapse portion 2222 and a third collapse portion 2223, the first collapse portion 2221 is connected to the connecting portion 221 on the side away from the second collapse portion 2222, the third collapse portion 2223 is connected to the hole wall of the collapse hole 11 on the side away from the second collapse portion 2222, and the second collapse portion 2222 is curvedly extended and arranged between the first collapse portion 2221 and the second collapse portion 2222. The first collapse portion 2221 is arranged at an angle with the connecting portion 221, and the third collapse portion 2223 is arranged at an angle with the hole wall of the collapse hole 11. The first collapse portion 2221 arranged at an angle with the connecting portion 221, the second collapse portion 2222 arranged at an angle with the hole wall of the collapse hole 11, and the second collapse portion 2222 curvedly extended are all more easily deformed when the collision occurs, thereby further reducing the damage to the head.

[0035] In some embodiments, Figure 3As can be seen in the cross-sectional view, the first collapsing portion 2221 and the second collapsing portion 2222 are both flat structures, the second collapsing portion 2222 is connected by multiple bending portions, and the length of the second collapsing portion is less than the length of the first collapsing portion 2221 and the length of the third collapsing portion 2223.

[0036] In some embodiments, referring to Figure 2 and Figure 4 As shown, the first connecting rib 21 includes a first protruding portion 211, and the second connecting rib 22 includes a second protruding portion 223. The first protruding portion 211 and the second protruding portion 223 are arranged to protrude away from the collapsing hole 11. The first protruding portion 211 and the second protruding portion 223 arranged to protrude away from the collapsing hole 11 can increase the structural strength of the first connecting rib 21, thereby increasing the structural strength of the connecting rib strip 20.

[0037] In some embodiments, referring to Figure 2 and Figure 4 As shown, the first protruding portion 211 forms a first recessed portion 2111, and the second protruding portion 223 forms a second recessed portion 2231. The first recessed portion 2111 and the second recessed portion 2231 are arranged to recess toward the collapsing hole 11. The first recessed portion 2111 and the second recessed portion 2231 are used to fill glue, thereby connecting the front nacelle outer plate. The size and number of the first recessed portion 2111 and the second recessed portion 2231 are set according to actual needs. Specifically, multiple first recessed portions 2111 are arranged at intervals, and the second recessed portion 2231 is arranged on the side of each second connecting rib 22 close to the first connecting rib 21. The contact area of the first connecting rib 21 with the front nacelle outer plate is greater than the contact area of a single second connecting rib 22 with the front nacelle outer plate, so multiple first recessed portions 2111 are arranged at intervals on the first connecting rib 21, and one second recessed portion 2231 is arranged on a single second connecting rib 22. This can increase the connection strength of the front nacelle outer plate.

[0038] In some embodiments, when the impact position is located at other parts of the human body, such as the shoulder, chest, waist, etc., the front nacelle inner plate of the present application can also reduce the damage to the corresponding position.
