Self-chargeable economizing generator

The utility model relates to a generator, in particular to an energy-saving self-charging type generator, which makes full use of energy. The technical solution is that the utility model comprises a support (4), an angle iron (3), a storage battery (1), a motor (2) and a drive system (10). The storage battery (1) and the motor (2) are fixed to the support (4). Wherein, a reducer (6) is connected with and driven by the motor (2) through a driving belt (5). The generator (9) is connected with and driven to generate by the reducer through a chain (7) and large and small sprockets (8). An output terminal of the generator is connected with an input terminal of the storage battery through an electric wire (11). The utility model has advantages that: when the device braking or slowing down, residual energy in the motor can be fully utilized to generate electricity by connecting the generator with the motor, which can recharge the storage battery and make full use of energy, thereby realizing minimum energy consumpti
