The upper and lower surfaces of the right end of the reinforcing plate are respectively welded with the lower surface of the left end of the supporting plate and the corresponding surface of the front cover inner plate, and damping rubber is arranged between the right end of the supporting plate and the front cover outer plate. The utility model discloses rational in infrastructure, and manufacturing is easy, can alleviate the pedestrian in the injured degree when colliding with an automobile, has good performance in the aspect of performance such as rigidity, intensity, mode and anti concavity again.
Description
Technical Field
The utility model relates to a supporting structure of car protecgulum.
Background
In order to ensure that the front cover of the automobile can be normally opened and closed, a reinforcing plate needs to be added at the positions for installing the hinge and the lock so as to ensure that the hinge and the lock cannot deform inadmissibly in the movement process, so that the corresponding rigidity and strength need to be ensured, and the anti-concave performance is improved. In increasingly stringent N-CAP scores, weakening of the front cover assembly is more desirable to ensure a score of a pedestrian head impact. The reinforcing plate and the supporting plate ensure rigidity, strength, mode and dent resistance, and simultaneously ensure small deformation of the front cover head during collision, little score and N-CAP star level reduction. Therefore, it is a significant research topic to solve the problem of how to structurally provide a front cover bracket with high pedestrian head collision protection performance, and good performances in terms of rigidity, strength, mode, dent resistance and other performances.
Patent No. ZL 02812868.0, entitled "vehicle body with elastically supported front cover", discloses that the vehicle body relates to a front cover structure of a vehicle to reduce the injury of a pedestrian in collision with the vehicle, but focuses on how to reduce the injury of the pedestrian in collision with the vehicle, and does not relate to how to ensure good performance of the front cover in terms of rigidity, strength, mode and dent resistance.
Disclosure of Invention
The main object of the present invention is to provide a support structure for a front cover of an automobile, which can reduce the injury degree of pedestrians when colliding with an automobile and has good performance in terms of rigidity, strength, mode and anti-concavity.
The utility model discloses used technical scheme is: a support structure of an automobile front cover comprises a front cover outer plate, a front cover inner plate, a front cover hinge and a reinforcing plate. The left end of the front cover inner plate is inserted into the folding groove at the left end of the front cover outer plate. The left end of the reinforcing plate is welded with the inner plate of the front cover, and the front cover hinge is fixedly connected with the surface of the inner plate of the front cover by bolts and corresponding nuts which penetrate through the reinforcing plate and the inner plate of the front cover. Also comprises a supporting plate. The upper and lower surfaces of the right end of the reinforcing plate are respectively welded with the lower surface of the left end of the supporting plate and the corresponding surface of the front cover inner plate, and damping rubber is arranged between the right end of the supporting plate and the front cover outer plate.
Preferably, a weakening rib is provided between the left and right ends of the support plate.
Preferably, the right end of the reinforcing plate and the left ends of the front cover inner plate and the supporting plate are welded together by spot welding, and the left end of the reinforcing plate and the front cover inner plate are welded together by spot welding.
Preferably, the surfaces of the folding grooves at the left end of the front cover inner plate and the left end of the front cover outer plate are glued together.
The utility model has the characteristics of it is following: the hinge setting position is located between the front end and the rear end of the reinforcing plate, and a section of gap is respectively arranged between the front side of the hinge, the right reinforcing plate and the front cover inner plate, so that the hinge mounting position can be ensured to have corresponding rigidity and strength, the supporting plate can select corresponding soft materials with proper thickness according to the requirements of outer plate dent resistance and pedestrian protection, the arrangement of the weakening ribs can play a role in guiding the supporting plate to crush when the head of a pedestrian collides with the front cover outer plate, and thus, the front cover outer plate dent resistance can be ensured to be good, and the front cover outer plate dent resistance is favorable for ensuring the safety of the pedestrian. The reinforcing plate, the supporting plate and the front cover inner plate are welded together in a spot welding mode, machining efficiency is high, machining and manufacturing cost is low, and the size of the reinforcing plate is determined to be beneficial to weight reduction of an automobile. Through CAE analog simulation calculation, the utility model discloses the modal value of protecgulum assembly can also be increased. The utility model discloses it is rational in infrastructure, and manufacturing is easy.
