Problems solved by technology
However, in actual accidents, there are fewer cases of head-on collisions, and the most common ones are often side impacts. However, there are no buffer devices such as energy-absorbing boxes in the side doors of most cars, so it is very easy to cause damage to passengers when an accident occurs. harm
The existing energy-absorbing box is generally connected between the front bumper and the frame, and placed in the door, its energy-absorbing effect is not up to standard, so it is not suitable for use on the side of the car body

Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] refer to Figure 1 to Figure 5 , a car side impact crash box, including a crash box body arranged between the car door trim 1 and the car body, the crash box body 2 is a tetrahedral shell with a hollow inside and an opening at the bottom Body, the shape of the left and right sides 3 of the energy-absorbing box body 2 is a trapezoid with a small top and a large bottom. Notches 4 are opened at the intersection of each side of the energy-absorbing box body 2, and the grooves The opening 4 is arranged at the bottom end of each side, and a reinforcing rib 5 is provided between the upper end surface and the front side of the crash box body 2 .
[0023] The bottom surface of the crash box body 2 extends outward to form several fixing plates 6 , and the fixing plates 6 are provided with ultrasonic installation holes 7 . Preferably, t...

The invention discloses a car side impact energy absorption box. The car side impact energy absorption box comprises an energy absorption box body arranged between a car door trim and a car body. The energy absorption box body is a hollow tetrahedral shell with bottom open. The shape of the left side face and the right side face of the energy absorption box body is big-end-down trapezoid. Notches are formed in junctions of all side faces of the energy absorption box body and formed in the bottom ends of the all side faces. A reinforcing rib is arranged between the upper end face and the front side face in the energy absorption box body. The car side impact energy absorption box is simple in structure, convenient to assemble, good in stability and obvious in actual energy absorption effect.
Description
technical field [0001] The invention relates to an automobile side impact energy absorbing box. Background technique [0002] With the development of society, cars are no longer an unattainable luxury, and more and more people start to own their own cars. With the increase in the number of cars, the number of traffic accidents has also increased significantly. Since the weight of the car is generally about 1.5 tons, and the driving speed is not low, once an accident occurs, it is likely to cause huge damage to the body or the vehicle itself. [0003] Under normal circumstances, the most destructive when collided with a vehicle traveling oppositely, so the crash box is often installed on the front bumper of the car, so as to reduce the impact on the vehicle and personnel. However, in actual accidents, there are fewer cases of head-on collisions, and the most common ones are often side impacts. However, there are no buffer devices such as energy-absorbing boxes in the side d...
