Description
Technical Field
The utility model relates to a car collision safety technical field, in particular to promote structure and car of car A post collision performance.
Background
At present, 25% offset collision is a collision condition with extremely high requirements on the structural strength of a vehicle body, and from test results issued by C-IASI (China Institute automatic Safety index) and IIHS (Institute for Highway Safety), the integrity of the whole vehicle body structure is damaged after collision of many vehicles. In the 25% offset crash test, there is often a problem of tearing at the outer panel and inner panel joint of the a-pillar of the automobile.
In the prior art, two schemes are mainly adopted: firstly, the impact force received by the connection flanging of the outer plate and the inner plate of the automobile A column in the collision process is evenly distributed by increasing the number of welding spots, so that the stress condition of a single welding spot can be reduced. For some vehicle types with small impact force, the problem that welding spots at the connecting flanges of the outer plate and the inner plate of the A column of the vehicle fail can be solved well; and secondly, structural glue is added at the connecting flanging position of the outer plate and the inner plate of the automobile A column, and the connecting flanging position of the outer plate and the inner plate of the automobile A column is bonded together through the structural glue, so that the structural glue has a remarkable effect of improving the tearing of welding spots at the connecting flanging position of the outer plate and the inner plate of the automobile A column. The automobile A-pillar (A-pillar) is a connecting pillar for connecting the roof and the front cabin on the left front side and the right front side, and can block a part of turning vision between the engine cabin and the cockpit and above the left rear-view mirror and the right rear-view mirror.
However, the new energy automobile has larger weight and can reach 2000kg-2600kg, the collision energy is increased more, and the stress on the connecting flanging parts of the outer plate and the inner plate of the A column of the automobile can reach 400 KN-500 KN. The number of welding points is increased in the first use scheme, the stress of the local welding points still exceeds the limit value which can be borne by the welding points, the local welding points are torn, the whole welding points are torn, and fatal damage is caused to a vehicle body and passengers. The structural adhesive is added by using the second scheme, and the connecting strength limit of the adhesive is also exceeded. Therefore, the problem that the connecting flanging part of the outer plate and the inner plate of the A column of the automobile is easy to tear when being collided is difficult to be completely solved by a single mode of increasing the connecting strength.
