The invention discloses a novel brake energy recycling device of a new-energy automobile. The device comprises an automobile brake device and a torsional spring energy conversion device. the automobile brake device comprises a two-segment type brake pedal plate, a hydraulic oil cylinder and a brake block which are sequentially connected, and the torsional spring energy conversion device comprises torsional springs, electric generators, a storage battery, an electronic switch, a reserve motor, a gear A and a gear B; the brake pedal plate is connected with an angular sensor, and the angular sensor is connected with the input end of an ECU; one output end of the ECU is connected with the electronic switch, and the electronic switch is connected with the reverse motor; an output shaft of the reverse motor is connected with one end of the gear A, and the gear A is meshed with the gear B; and the gear B is fixedly connected with one ends of the torsional springs, and the other ends of the torsional springs are fixed to axles of wheels. By means of the device, kinetic energy of the automobile is directly converted into elastic potential energy to be stored in the torsional springs, running brake is achieved, the efficiency of energy recycling is improved, and energy of friction losses is greatly reduced.
