Summary of the invention
The utility model provides a kind of drive motors structure that is applied to small-sized pure electric automobile, and one of purpose is under the prerequisite that does not increase radial dimension, reduces axial dimension effectively, thereby reduces the motor overall volume, satisfies the requirement of arrangement space; Two of purpose provides a kind of terminal box scheme that does not adopt connector, and the external dimensions of further dwindling electric system satisfies the requirement of arrangement space.
For realizing above-mentioned purpose; The drive motors structure of a kind of electric automobile that the utility model proposes comprises motor housing; Be arranged on motor electromagnetic parts, the cooling jacket in the motor housing and revolve the change system; Be arranged in the three-phase power line of the outer cooling water nozzle of motor housing, terminal box and inverter output, and the motor three phase winding lead-out terminals that pass in the motor.The three-phase power line of said inverter output is connected in terminal box with said motor three phase winding lead-out terminals; Said terminal box is installed in the circumferential surface of motor housing and near revolving the change system; Said cooling water nozzle is pressed close to motor housing and is installed; The upper surface of described terminal box flushes with motor housing cylindrical tangent line.
Further, the three-phase power line of inverter output is connected by connector with motor three phase winding lead-out terminals in terminal box.Specific practice is: each of the three-phase power line of said inverter output is pressed into one with a connector respectively mutually and inserts in the terminal box, and the connector of each phase of the three-phase power line of inverter output is corresponding respectively again to be connected with motor three phase winding lead-out terminals.
The concrete structure of the connector in the terminal box is: an end of connector is a through-hole structure, and the multiturn high-voltage conducting wires inserts in the through hole, is packed together to integral body through external force and connector, and the other end of connector is a laminated structure, and this end is provided with connecting hole.
For guaranteeing the protection and the insulation of high-voltage line, the three-phase power line of inverter output wherein is socketed in the protecting tube, and the contact point of its protecting tube and terminal box carries out encapsulation process; The part of motor three phase winding lead-out terminals entering terminal box is enclosed within takes over control in the pillar.
The advantage of the utility model is following:
1, adopts owing to the circumferential surface and the upper surface that terminal box are arranged on motor housing flush with electric machine casing cylindrical tangent line; And be in the same side with motor cooling turnover water nozzle; And water nozzle is pressed close to motor housing, does not increase the axial length of motor, can make full use of the motor axial space.
2, terminal box does not adopt the mode of connector to connect; But after the three-phase power line of inverter output and connector be pressed into integral body; Directly be inserted in the terminal box, be connected with motor three phase winding lead-out terminals through simple connection securing member, syndeton is simple; The bulk of motor can be effectively reduced, and certain cost can be reduced.
Adopt the utility model, the axial dimension of motor can reduce about 30%, satisfies the space requirement of pure electronic compact car.Owing to simplified the connected mode of terminal box, reduce outside connector in addition, can reduce the whole cost of product.
