The invention discloses a bumper with buffering and damping functions. The bumper comprises a bumper body, a protection plate, a cross beam, fixing bolts, a first damping spring, a first buffer block,a second buffer block, a buffer plate, a guide rod, a second damping spring and a third damping spring. The protection plate is arranged above the bumper body; the two ends of the bumper body are fixedly connected with the cross beam through fixing bolts, the fixing bolt is sleeved with the first damping spring, the first buffer block is arranged in the middle of the lower surface of the bumper body, the second buffer block is arranged in the middle of the upper surface of the cross beam, the upper end of the guide rod is arranged below the first buffer block, and the lower end of the guide rod penetrates the buffer plate and is arranged above the second buffer block. According to the bumper, the protection plate, the buffer plate and the cross beam are additionally arranged, the multiplesets of damping springs are arranged between the protection plate and the buffer plate and between the buffer plate and the cross beam, the strength of the bumper is effectively enhanced, and meanwhile a good buffer effect can be achieved.
