Detailed Description

To further illustrate the technical means and effects of the present invention for achieving the objects of the present invention, the detailed description of the specific embodiments, structures, features and effects of the crumple engine cover stiffener according to the present invention will be made with reference to the accompanying drawings and the preferred embodiments.

As shown in fig. 1, the inner engine cover plate and the crumple engine cover reinforcing plate 1 of the present invention are shown, and the outer engine cover plate (not shown in the figure) covers the crumple engine cover reinforcing plate 1. When a pedestrian collides against the hood outer panel at the head of the vehicle, the impact force is transmitted to the crumple hood reinforcing plate 1 by the hood outer panel, and the crumple hood reinforcing plate 1 is crumpled to protect the pedestrian.

As shown in fig. 2, the cover reinforcing plate 1 of the crumple engine includes a plurality of supporting legs 3 that support frame 2 and be connected with support frame 2, but support frame 2 and a plurality of supporting legs 3 integrative stamping forming. The support frame 2 forms a frame of the entire collapsed bonnet reinforcing plate 1 and is brought into abutment with the bonnet outer panel for supporting the bonnet outer panel, and the plurality of support legs 3 include a plurality of front support legs 31 and a plurality of rear support legs 32, wherein, referring to fig. 1, the azimuth "front" is defined as a direction of the vehicle toward the head in the length direction, and the azimuth "rear" is defined as a direction of the vehicle toward the tail in the length direction. Fig. 2 shows 2 front support legs 31 and 2 rear support legs 32, it is understood that the number of the front support legs 31 and the rear support legs 32 can be set as required, for example, 3 front support legs 31 and 3 rear support legs 32 are provided, or 2 front support legs 31 and 3 rear support legs 32 are provided, and at least 2 front support legs 31 and 2 rear support legs 32 are required to ensure the collapsing effect.

As shown in fig. 3, the front support leg 31 is formed with a first bent portion 311 bent toward the rear, and the rear support leg 32 is formed with a second bent portion 321 bent toward the rear. By forming the first bent portion 311 bent toward the rear portion on the front support leg 31 and the second bent portion 321 bent toward the rear portion on the rear support leg 32, when a pedestrian collides against the hood outer panel at the head of the vehicle, both the front support leg 31 and the rear support leg 32 collapse toward the rear portion, that is, in the same direction toward the rear portion (the direction away from the pedestrian), collapse in the direction farthest from the pedestrian is realized, and the impact energy is released to the maximum to protect the pedestrian. In addition, in the actual design, the first bent portion 311 has a larger folding angle than the second bent portion 321, so that the impact force is firstly restrained by the first bent portion 311 having a larger folding angle and then restrained by the second bent portion 321 having a smaller folding angle, thereby further ensuring that the collapse direction does not deviate from the design direction when the collapse occurs. Preferably, the first bent portion 311 may have a bent angle of 145 ° to 155 °, for example, 150 °. The second bend may have a bend angle of between 125 ° and 135 °, for example 130 °.

Further, as shown in fig. 2, a longitudinal rib 33 is further provided on the plurality of support legs 3 in the longitudinal direction to ensure the support strength of the collapsed bonnet reinforcing plate 1, and the orientation "longitudinal" is defined as along the longitudinal length direction of the support legs 3. The vertical reinforcing rib 33 forms a collapsing part 34 at the intersection with the first bending part 311 and the second bending part 321, respectively, and when the stress on the collapsing bonnet reinforcing plate 1 reaches a peak value, the collapsing part 34 can collapse in the design direction by concentrating the stress.

Further, as shown in fig. 3, the collapse bonnet reinforcing plate 1 is further provided with a plurality of support legs 5 connected to the plurality of support legs 3 at end portions of the plurality of support legs 3, the support legs 5 are abutted to the bonnet inner plate shown in fig. 1, and the support legs 5 can be integrally press-molded with the support legs 3. Fillet 4 is formed between a plurality of supporting legs 3 and a plurality of supporting legs 5 respectively, and the size of fillet 4 can be decided according to stamping process and structural strength, and the great easy collapsibility that produces of fillet 4, fillet 4 are preferably 120.

The above embodiments are merely descriptions of the collapsed bonnet reinforcing plate. It can be understood that the crumple bonnet reinforcing plate of the utility model is not only used for the bonnet, but also can be applied to other structures to generate crumple, thereby achieving the purpose of protection, for example, can be applied to structures such as an anti-collision fence to protect people or vehicles impacting on the anti-collision fence.

Above, the beneficial effects of the utility model include at least: the beneficial effects of the utility model include at least: the break angle that forms second kink and first kink towards the rear portion on forming the first kink towards the rear portion on the preceding supporting leg, the back supporting leg and have is greater than the break angle that the second kink has to realize pedestrian and locomotive collision back, the cover reinforcing plate that bursts to contract along the direction far away from pedestrian, furthest releases the impact energy and reaches the effect that reduces the head and bump the injury.
