Description

Preceding guarantor's grid mounting structure

Technical Field

The utility model belongs to the technical field of auto-parts, concretely relates to preceding guarantor grid mounting structure.

Background

In the collision accident between an automobile and a person, the front part of the automobile usually collides with the legs of the person, the leg collision mainly examines the force and the bending moment of the legs, and the key factors influencing the two indexes are the front modeling of the automobile and the front structural rigidity. The shape mainly influences the collision angle and energy of thighs, and the energy absorption of thighs is influenced by the strength of the rigidity of the front structure. The influencing factors of the front structural rigidity comprise structures such as a hood body, a hood lock, a front upper grille, a grille mounting bracket, a radiator beam and the like. The front bumper is rigidly connected with the upper crossbeam support of the radiator through the upper grid support, when a thigh impacts a grid, energy absorption is realized by a mode that deformation or a mounting point of the support can be broken generally in the prior art scheme, but due to structural limitation, resistance of the front bumper is large or failure instability is caused, deformation of the front bumper is small depending on a structure in a collision process, a connection structure cannot further generate movement buffering, thigh collision energy cannot be effectively absorbed, and the thigh is stressed greatly, so that the thigh of a pedestrian is seriously collided in the collision process, meanwhile, the front stability of the automobile in the driving process is also a factor to be considered, and therefore, how to reduce the damage of the collision to the pedestrian to the maximum extent and how to ensure that the front bumper grid of the automobile in the driving process is stable is a problem to be considered and solved by technical.

The Chinese patent number is CN202686245U, the publication date is 2013, 1, 23 and discloses a connecting structure of a grille, which comprises a grille connected with a radiator beam, a grille support is arranged on the grille, and a buffering connecting structure is arranged between the grille support and the radiator beam.

When the automobile collides with a pedestrian, the grille is quickly contracted through the buffer structure between the grille bracket and the radiator, so that the injury to the legs of the pedestrian in the collision process is reduced.

However, the grille support is provided with the blocking piece opening near the fixing hole, when an automobile jolts in the driving process, the bolt easily moves towards the direction of the guide groove from the fixing hole, the grille support retracts backwards, the front security installation and positioning requirements cannot be met, the gap between the front security installation and the hood is unstable, the front security grille cannot be guaranteed to be fixed in the driving process of the automobile, and the front security grille is prone to droop due to jolt in the driving process of the automobile.
