A wheel-embracing mechanism and a safety vehicle having the wheel-embracing mechanism. The wheel-embracing mechanism comprises a forward-pushing base arranged in front of a wheel, a rearward-pulling base arranged behind the wheel, and a downward-pressing base arranged above the wheel. The forward-pushing base and the rearward-pulling base are connected via upper and lower gearboxes (44 and 33). The lower gearbox (33) has arranged thereon resistant springs (51 and 37). The downward-pressing base is hinged respectively to the forward-pushing base and to the rearward-pulling base via hinge elements. The wheel-embracing mechanism allows forces of impact generated by a collision to be converted, after being cushioned and reduced by the multiple resistant springs, into oppositely-pressing and vertically downward-pressing forces, thereby embracing the wheel at the same time, utilizes the great load-bearing and pressure-resistant performances of a pneumatic tire of the wheel to transmit the forces of impact to the ground, thereby protecting the vehicle body structure from being crushed and damaged by the forces of impact, thus increasing safety protection for an occupant in the vehicle, and achieving three safety effects of collision resistance, vehicle protection, and occupant protection. |
