Power-driven direct current motor of electric automobile

Abstract

The invention discloses a power-driven direct current motor of an electric automobile. A top cover is arranged at the upper end of a shell, a bottom cover is arranged at the lower end of the shell, a driving output mechanism is arranged at the upper end in the shell, a power generation rotor is arranged at the lower end in the shell, a switching mechanism is arranged on one side of the middle in the shell, an air cooling mechanism is arranged at the lower end in the shell, and a cold water tank is arranged below the bottom cover. A heat exchange coil is arranged in the inner cavity of the shell, a connecting pipe is arranged below the inner side of the top cover, a micro water pump is arranged on the outer side of the top cover, and a circulating pipe is arranged on the side face of the shell. The internal air cooling mechanism is matched with circulating water cooling, heat exchange and heat dissipation can be conducted from the interior of a driving motor, the double heat dissipation effect is good, meanwhile, through integrated arrangement of a power generation rotor and a driving output mechanism, the motor achieves effective conversion and utilization of kinetic energy of the automobile when the automobile slides and does not work, energy waste is avoided, meanwhile, the switching mechanism can freely control connection or disconnection of the power generation rotors according to requirements, adjustment is convenient, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of driving motors, in particular to a power-driven DC motor of an electric vehicle. Background technique [0002] With the impact of the energy crisis on the automobile industry, the research and development and utilization of electric alternative vehicles have been gradually carried out. The key technical points of electric vehicles are mainly batteries, chargers, motors and controllers, among which the motor is the most important factor affecting the efficiency of electric energy utilization. An important factor, the DC drive motor has become the drive motor commonly used in electric vehicles; [0003] The drive motor in the prior art needs to dissipate heat from the motor with the help of an external heat dissipation mechanism. The heat generated during the internal operation of the motor cannot be dissipated quickly, and it is very easy to cause dangerous situations such as damage, combustion and explosi...

Problems solved by technology

[0003] The drive motor in the prior art needs to dissipate heat from the motor with the help of an external heat dissipation mechanism. The heat generated during the internal operation of the motor cannot be dissipated quickly, and it is very easy to cause dangerous situations such as damage, combustion and explosion. At the same time, the existing motor can only drive the vehicle , the kinetic energy will be wasted when the vehicle slides, therefore, the present invention proposes a power-driven DC motor for electric vehicles to solve the problems in the prior art
