[0021] See also Figure 1-2, a regenerative suspension for automobile collision test, including channel steel a1, which is vertically fixed to the body-in-white. The channel steel a1 is connected to the body-in-white by welding to ensure firmness, reliability and vertical levelness. The two legs of the channel steel a1 are respectively provided with a number of vertical through slots, and the channel steel a1 is installed with the channel steel b2, and the channel steel b2 is provided with through holes adapted to the through slots of the channel steel a1. Among them, the two legs of the channel steel a1 are respectively provided with two vertical through slots, and the two legs of the channel steel b2 are respectively provided with two through holes adapted to the through slots. The channel steel a1 and the channel steel b2 are fixed by bolts, and the bolts pass through the adapted through slots and through holes. The channel steel a1 and the channel steel b2 are fixed by bolts, and the height of the vehicle body can be adjusted by relying on the long strip slots of the channel steel a1, and it can also be easily installed so that the vehicle after the collision test can be restored to the state before the test.
[0022] Channel steel b2 is fixedly connected to channel steel c3, and the waists of channel steel b2 and channel steel c3 fit together. The two legs of channel steel c3 are fixedly connected to vertical plane steel b7. Channel steel b2 and channel steel c3 are fixed together by welding, and plane steel b7 is also fixed together with channel steel c3 by welding. The side wall of plane steel b7 is fixedly connected to angle steel a5 and angle steel b6, and angle steel a5 and angle steel b6 are fixedly connected to horn bearing assembly 8. Angle steel a5 and angle steel b6 are mirror-set. Angle steel a5 and angle steel b6 both have two through holes, and horn bearing assembly 8 is provided with through holes that match angle steel a5 and angle steel b6.
