Description

A front grille installation structure

technical field

The utility model belongs to the technical field of auto parts, in particular to a front grille installation structure.

Background technique

In the collision accidents between cars and people, the front of the car usually collides with the legs of people. The thigh collision mainly examines the force and bending moment of the leg shape. The key factors affecting the two indicators are the shape of the front of the vehicle and the Front structural stiffness. The shape mainly affects the collision angle and energy of the thigh, and the rigidity of the front structure affects the energy absorption of the thigh. The influencing factors of the rigidity of the front structure include the hood body, hood lock, front grille, grille mounting bracket, radiator beam and other structures. The front bumper is rigidly connected to the upper beam bracket of the radiator through the upper grille bracket. When the thigh impacts the grille, the existing technical solution generally realizes energy absorption through the deformation of the bracket or the way that the installation point can be collapsed. However, due to structural limitations, its The resistance is large or the failure is unstable, the deformation of the dependent structure is small during the collision process, the connecting structure cannot further move and buffer, the collision energy of the thigh cannot be effectively absorbed, and the thigh is subjected to a large force, which leads to the pedestrian's thigh during the collision. Serious collisions occur, and at the same time, the stability of the front of the car during driving is also a factor to be considered. Therefore, how to minimize the damage caused by the collision to pedestrians and ensure the stability of the front grille of the car during driving is an important issue. Problems to be solved by those skilled in the art.

The Chinese patent number is CN202686245U, the date of publication is January 23, 2013, and a connection structure of a grille is disclosed, including a grille connected with a radiator beam, the grille is provided with a grille bracket, the grille There is a buffer connection structure between the grille bracket and the radiator beam.

When a car collides with a pedestrian, the grille rapidly shrinks through the buffer structure between the grille bracket and the radiator, thereby reducing the damage to the pedestrian's calf during the collision.

However, the disadvantage is that the grille bracket of the above-mentioned application has an opening near the fixing hole. When the car is bumpy during driving, the bolts are easily moved from the fixing hole to the direction of the guide groove, so that the grille bracket retreats backward, which cannot meet the front protection requirements. Installation and positioning requirements, the gap between the front bumper and the hood after installation is unstable, and it is impossible to ensure that the front bumper grille is fixed during the driving process.

SUMMARY OF THE INVENTION

In the above-mentioned front grille installation structure, there is a gap between the insertion end of the anti-sagging bracket and the bottom of the card slot, and when the car collides, the gap provides space for the anti-sagging bracket to retreat;

The anti-sagging bracket is provided with a guiding reinforcing rib, and the guiding reinforcing rib is clamped with the clamping slot to enhance the strength of the anti-sagging bracket, and the anti-sagging bracket and the clamping groove are stably retreated through the guiding reinforcing rib;

The grille bracket is provided with a guide groove and a bolt installation hole, and a buffer connection structure is formed between the guide groove and the bolt installation hole by a baffle plate. The baffle plate prevents the grille bracket from sliding and ensures the positioning and stability of the front grille. When the car collides, the bolts break the shield, and the grille bracket shrinks backward along the guide groove through the bolts, so that the energy-absorbing structure between the grille and the radiator can absorb the deformation and energy to the greatest extent, and reduce the energy to the greatest extent. Injury to the pedestrian's calf caused by the collision;

The width of the guide groove is not less than the diameter of the bolt installation hole, which is conducive to the sliding of the bolt to the guide groove;

The beam bracket is provided with a connection hole, the connection hole is opposite to the bolt installation hole, the beam bracket and the grid bracket are connected by bolts, and the connection hole and the bolt installation hole are convenient for bolt fixing connection;

The number of said grille brackets is at least four, and the number of said anti-sagging brackets is at least two, and the plurality of grille brackets and anti-sagging brackets make the fixing effect better, the stability better, and prevent the front grille from sagging.

Compared with the prior art, the advantages of the present utility model are as follows:

When a car collides with a pedestrian, the collision force is transmitted to the grille bracket and the anti-sagging bracket through the grille. The radiator beam is provided with a beam bracket that forms a buffer connection with the grille bracket. The front grille will buffer and shrink to prevent sagging. The bracket moves and contracts backwards, so that the energy-absorbing foam or energy-absorbing box located inside the front bumper can absorb the collision kinetic energy to the maximum extent, and the double action makes the grille contract backwards within the collision range of the thigh, providing energy-absorbing space for the collision of pedestrians' thighs. , to minimize the damage caused by collision to pedestrians' thighs, there is also an anti-sagging bracket on the grille to prevent the front bumper from sagging in the bumpy and jittery conditions of the vehicle, and to ensure the front grille of the car during driving. Stablize.
