Safe direct-current long-line charger for electric bicycle

Abstract

The invention relates to the technical field of electric vehicle charger protection, and further discloses a safety direct-current long-line charger for the electric bicycle. The safety direct-currentlong-line charger for the electric bicycle comprises a shell; a meshing wheel is movably connected to the interior of the shell; the surface of the meshing wheel is movably connected with a rotatingshaft; the upper end of the rotating shaft is sleeved with a winding rod; a wire is wound on the surface of the winding rod; the surface of the rotating shaft is movably connected with a spring rod; the upper end of the spring rod is movably connected with a light receiving plate; the surface of the spring rod is movably connected with an air bag; the other side of the air bag is movably connectedwith an extrusion rod; the other end of the extrusion rod is movably connected with a push plate; and the bottom of the push plate is movably connected with an extension frame. At the moment, a large-capacity electrolytic capacitor is arranged in the wire, and the current has flowability, so that the current can be attracted by the resistor block and flows into the resistor block, the impact current can be absorbed by the resistor block at the moment, the current can be changed into heat to be dissipated as time goes on, and the effect of weakening the influence of the current on a transformer in the charger is achieved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charger protection, in particular to a safe DC long-line charger for electric bicycles. Background technique [0002] The electric vehicle charger is a charging device specially configured for the battery of an electric bicycle. It belongs to a separate accessory for the vehicle. There are two types of forward type and flyback type, of which the single excitation type has a higher market share; Regarding the use of the charger, the correct operation steps are: when charging, first insert the battery, and then add the mains power; Cut off the utility power, and then pull out the battery plug. [0003] Due to the large volume of electric vehicles, it is necessary to place the vehicle outdoors for charging, and charging outdoors will expose the charging line to wind and sun erosion, and more importantly, the outdoor voltage is different from the indoor voltage, so when charging, It will ca...

Problems solved by technology

[0003] Due to the large volume of electric vehicles, it is necessary to place the vehicle outdoors for charging, and charging outdoors will expose the charging line to wind and sun erosion, and more importantly, the outdoor voltage is different from the indoor voltage, so when charging, It will cause the inside of the charger to be impacted by current, which will greatly shorten the service life of the charger in the long run, and it is prone to electric leakage and hurt people. Therefore, a safe DC long-line charging for electric bicycles came into being.
