Detailed Description

Embodiments of the present utility model will be described in detail below, by way of example with reference to the accompanying drawings.

A crash box mounting assembly 1 according to an embodiment of the present utility model is described below with reference to fig. 1 and 2.

As shown in fig. 1, a crash box mounting assembly 1 according to an embodiment of the present utility model includes: a front lower impact beam 10, a subframe rail 20, and a crash box 30. The front lower impact beam 10 is generally located at the front lower end of the vehicle and is primarily capable of absorbing impact energy when the vehicle is involved in a collision. The sub-frame rail 20 is a structural portion of the sub-frame and may serve to support the vehicle body. The crash box 30 can absorb crash energy when the vehicle is involved in a crash.

As shown in fig. 1, in the front-rear direction, one end of the crash box 30 is connected to the front lower impact beam 10, and the other end of the crash box 30 is connected to the sub-frame rail 20. That is, in the front-rear direction, both ends of the crash box 30 are respectively connected with the front lower impact beam 10 and the sub-frame side member 20, firstly, the arrangement of the crash box 30 can be made more stable, secondly, when the vehicle is impacted, the front lower impact beam 10 is subjected to impact force first, the front lower impact beam 10 can absorb part of impact energy, then the impact force is continuously transmitted to the crash box 30, and the crash box 30 re-absorbs part of the impact energy, thereby reducing the transmission of the impact energy to the sub-frame side member 20, minimizing the damage of the impact force to the sub-frame side member 20, and improving the protection performance for personnel in the vehicle.

As shown in fig. 1, the sub-frame rail 20 is provided with a hollow cavity, and the other end of the crash box 30, that is, the cross-sectional area of the end of the crash box 30 adjacent to the sub-frame rail 20 is smaller than the cross-sectional area of the hollow cavity, and the other end of the crash box 30 extends into the hollow cavity. That is, the end of the energy-absorbing box 30 connected to the sub-frame rail 20 is disposed in the hollow cavity, so that the other end of the energy-absorbing box 30 is offset from the sub-frame rail 20 in the up-down direction, and when the energy-absorbing box 30 is impacted, the energy-absorbing box can move in the front-back direction in the hollow cavity, thereby reducing the impact on the sub-frame rail 20 and improving the impact safety.

Therefore, the cross-sectional area of the other end of the energy-absorbing box 30 is smaller than that of the hollow cavity, and the other end of the energy-absorbing box 30 extends into the hollow cavity, so that the other end of the energy-absorbing box 30 and the auxiliary frame longitudinal beam 20 are staggered in the up-down direction, when the energy-absorbing box 30 collides and bears force, the collision speed is more favorable for slowing down, the deformation of the auxiliary frame longitudinal beam 20 is lightened, the low-speed collision is also favorable, the damage of collision force to the auxiliary frame longitudinal beam 20 can be further reduced, and the protection performance to personnel in a vehicle is improved.

The outer surface of the other end of the crash box 30 abuts against the inner surface of the hollow cavity.

That is, in the direction from the front lower impact beam 10 to the sub-frame rail 20, the cross-sectional area of the crash box 30 increases, and the corresponding cross-sectional force increases, so that the impact energy absorbing effect of the crash box 30 can be improved, the crash box 30 is more beneficial to safe collision, the lower surface of the crash box 30 forms an obtuse angle with the horizontal plane, and when the vehicle passes through an inclined plane or a convex road surface, the front lower impact beam 10 is higher, can be lifted by the support bottom to pass through the curb stone surface, can avoid frontal impact, and can further avoid damage to functional components.

Further, the value range of the included angle alpha is as follows: alpha is more than or equal to 150 degrees and less than 180 degrees. That is, the included angle between the lower surface of the energy-absorbing box 30 and the horizontal plane cannot be too small, that is, less than 150 °, so that the cross-sectional area of the energy-absorbing box 30 cannot be effectively increased, the corresponding increase of the cross-sectional force is limited, the effect of collision energy absorption of the energy-absorbing box 30 is not obvious, and of course, the included angle between the lower surface of the energy-absorbing box 30 and the horizontal plane cannot be 180 ° or more, so that the cross-sectional area of the energy-absorbing box 30 is unchanged, even reduced, and the design of the application is not met.
