Auxiliary energy absorption box device and vehicle

The utility model relates to the technical field of devices for absorbing impact, in particular to an auxiliary energy absorption box device and a vehicle. The auxiliary energy absorption box device is used for being connected with a vehicle auxiliary frame and comprises an auxiliary cross beam, an auxiliary energy absorption box and a short cross beam, the auxiliary cross beam is fixedly connected with one end of the auxiliary energy absorption box, the other end of the auxiliary energy absorption box is detachably connected with one end of the short cross beam, and the other end of the short cross beam is fixedly connected with the auxiliary frame. During low-speed collision, the auxiliary cross beam and the auxiliary energy absorption box deform, the short cross beam and the auxiliary frame do not deform, the vehicle is better protected, and the protection effect is better; during maintenance, only the auxiliary cross beam and the auxiliary energy absorption box need to be replaced, and the maintenance cos
