The invention discloses an electric automobile threshold stiffening beam, a framework and an automobile. The electric automobile threshold stiffening beam comprises a threshold beam body and a stiffening beam body. A cavity is formed in the doorsill beam body, the reinforcing beam body is of a hollow structure, and the cross section of the reinforcing beam body is a right trapezoid. The stiffening beam body is fixed in the inner cavity of the doorsill beam in a manner that the upper bottom is forward, the lower bottom is backward and the right-angle waist is downward; the right-angle waist of the stiffening beam body is connected with the doorsill beam body through a lower support, and the inclined waist of the stiffening beam body is connected with the doorsill beam body through an upper support. The anti-overturning performance and the collision performance of the stiffening beam body can be improved, and the weight of parts can be reduced.
