Vehicle body frame structure and vehicle

The invention provides a vehicle body frame structure and a vehicle. The vehicle body frame structure comprises a doorsill, a mounting profile and a wire harness. The mounting profile is arranged on one side of the doorsill in the Z direction and is connected to the doorsill; an installation cavity is formed in the installation profile, and the wire harness is arranged in the installation cavity. In the scheme, the mounting section bar is arranged on one side of the Z direction of the threshold, and the mounting cavity is formed by the mounting section bar, so that the mounting space is provided for the wire harness, the wire harness can be mounted in the mounting cavity in the mounting section bar, and the mounting section bar has certain protection performance; therefore, compared with the mode that the wire harness is arranged on the threshold, a reinforcing structure does not need to be additionally arranged to protect the wire harness, the installation space of the battery pack is effectively guaranteed,
