The invention belongs to the field of vehicles, and particularly discloses an electric vehicle buffer bumper. The electric vehicle buffer bumper comprises a bumper body, installation seats, buffer mechanisms and buffer modules. The two ends of the bumper body are separately connected with a vehicle body through the installation seats. Cavities are formed in the dumper body, the buffer mechanisms are installed in the bumper body in a sliding mode, and the buffer mechanisms are each formed by connecting a group of connecting rods in a cross hinged mode. The buffer modules are separately installed at the two ends of the buffer mechanisms. The buffer modules are used for connecting the vehicle body, and the buffer mechanisms can relieve the tension of the buffer mechanisms towards both ends. The electric vehicle buffer bumper spreads to both ends by sliding the buffer mechanisms inside the bumper body so as to achieve the function of energy dissipation and improve the protection of the vehicle body.
