The invention relates to a battery pack protection structure and a vehicle, and belongs to the technical field of battery pack protection. The electric protection structure comprises a first protection structure and a second protection structure. The first protection structure comprises a plurality of beam assemblies arranged at intervals in the longitudinal direction of a vehicle body, a central channel connected with each beam assembly and beam end plates located at the two ends of the beam assemblies, each beam end plate is used for being connected with the ends of all the beam assemblies, and the first protection structure is fixedly connected with a vehicle floor. A battery pack is fixed below the first protection structure and the vehicle floor; the second protection structure comprises a doorsill main beam forming a cavity and a doorsill protection beam located in the cavity, the doorsill main beam is connected with the cross beam end plate, the doorsill protection beam extends in the longitudinal direction of the vehicle body, the outer side of the doorsill protection beam is fixedly connected with the doorsill main beam, and the projection of the doorsill protection beam on the multiple cross beam assemblies in the transverse direction of the vehicle body covers the multiple cross beams. The battery pack protection structure and the vehicle can protect the battery pack and realize utilization space optimization in the battery pack.
