Wherein, the length direction is the X direction in Figure 3 , the width direction is the Y direction in Figure 3 , and the height direction is the Z direction in Figure 3 , and the Z direction is perpendicular to the plane formed by the X direction and the Y direction.

[0044] In the embodiments, two first bending parts 32 are arranged, and the two first bending parts 32 are respectively connected to the two ends of the lock buckle assembly body 31, so as to improve the stability of the support of the first bending part 32 to the engine cover outer plate 1. It can be understood that in other embodiments, the number of the first bending part 32 can be set as required.

[0045] In the embodiments, the first bending part 32 is integrally formed with the lock buckle assembly body 31, which is convenient for manufacturing. It can be understood that in other embodiments, the first bending part 32 and the lock buckle assembly body 31 can also be separately arranged.

[0046] The engine hood outer plate reinforcing plate is cancelled in the embodiment, and the engine hood lock buckle assembly 3 of the embodiment comprises a lock buckle assembly body 31 connected to one side of the engine hood inner plate 2 towards the engine hood outer plate 1 and a first bending portion 32, one end of the first bending portion 32 is connected to the lock buckle assembly body 31, and the other end of the first bending portion 32 extends along the height direction and is connected with the engine hood outer plate 1 to support the engine hood outer plate 1 through the first bending portion 32, thereby reducing the pedestrian collision injury value while ensuring the dent resistance of the engine hood outer plate 1, and reducing the weight of the engine hood assembly 100, thereby improving the overall lightweight of the vehicle.

[0047] Referring to Figure 4 The engine hood lock buckle assembly 3 further comprises a second bending portion 33 connected to one end of the first bending portion 32 away from the lock buckle assembly body 31, and the second bending portion 33 extends along the width direction, and the second bending portion 33 is provided with an abutting surface connected with the engine hood outer plate 1, and the first bending portion 32 of the embodiment is connected with the engine hood outer plate 1 through the abutting surface of the second bending portion 33, thereby increasing the connection area of the first bending portion 32 and the engine hood outer plate 1, and enhancing the stability and reliability of the connection of the first bending portion 32 and the engine hood outer plate 1.

[0048] In the embodiment, the abutting surface and the engine hood outer plate 1 are connected through shock-absorbing glue to reduce the vibration of the vehicle body and improve the riding comfort of the passengers.

[0049] In the embodiment, the second bending portion 33 and the first bending portion 32 are integrally formed, which is convenient for manufacturing, and it can be understood that in other embodiments, the second bending portion 33 and the first bending portion 32 can also be separately provided.

[0050] Referring to Figure 3 The engine hood outer plate 1 comprises an outer plate body 11 and a hem portion 12 connected to the peripheral side of the outer plate body 11, and the peripheral side of the inner plate body 21 is provided with a connecting portion, one side of the connecting portion is attached to the outer plate body 11, and the other side of the connecting portion is attached to the hem portion 12, that is, the engine hood outer plate 1 is wrapped in the engine hood inner plate 2 in a hemming structure formed by the hemming, thereby effectively improving the overall rigidity and strength of the engine hood assembly 100, and making the surface of the vehicle body more smooth, reducing the joints and protrusions, and improving the overall appearance of the vehicle.

[0051] As Figure 1 and Figure 2As shown, the existing automobile engine cover assembly structure mostly adopts a multi-main rib support structure or an "XX" support structure. The engine cover assembly inner plate rib 103' of the multi-main rib support structure has 3 main ribs, and the engine cover assembly inner plate rib 103' of the "XX" support structure has as many as 5 main ribs. The rib 103' has a depth of 20 mm. Due to the excessively large area of the rib 103' region, the inner plate of the two traditional structures often accounts for more than 50% of the entire engine cover area, resulting in high strength of the engine cover assembly 100. When the automobile collides with a pedestrian, the human injury value is high.

The dot-shaped shock-absorbing glues 4 can more accurately locate and process the vibration source, so that each dot can work independently, and the stress points are dispersed, thereby better absorbing and dispersing the vibration during the driving of the vehicle, providing more uniform shock-absorbing effect. Moreover, the dot-shaped shock-absorbing glues 4 are more convenient to coat, saving time and labor cost and improving production efficiency. It can be understood that in other embodiments, the multiple shock-absorbing glues 4 can also be distributed in a dot shape on the engine cover outer plate 1, or the multiple shock-absorbing glues 4 can also be distributed in a dot shape on the support 22 and the engine cover outer plate 1, respectively.
