Description
Technical field
The utility model relates to a kind of electric car travel increasing device.
Background technology
Along with the fast development of battery-driven car, rose in recent years a kind of battery-driven car with distance increasing unit with course continuation mileage function, and gradually for people are familiar with, accept and use.Existing electric vehicle distance increasing unit mainly comprises fuel engines, motor and controller three parts, wherein fuel engines and motor form electrical generator, motor comprises rotor and stator and tail-hood, end cap and motor casing, rotor is connected with fuel engines output shaft, stator and motor casing interference fit are as Chinese patent 2012201946110, motor casing is connected with fuel engines limit lid by bolt, and fan is contained on motor tail-hood on the one hand, and the wind of fan is poor to the cooling performance of generator.Trouble is installed on the other hand.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of generator good cooling results, electric car travel increasing device easy for installation.
The technical solution of the utility model is as follows:, a kind of electric car travel increasing device, comprise driving engine and electrical generator, it is characterized in that: described electrical generator comprises rotor (1), stator (2), outer cover (3) and support and connection dish (4), described outer cover (3) covers on support and connection dish (4), the middle inside of described support and connection dish (4) is provided with the boss (4a) of fixed stator (2), on described boss (4a), have centre hole, described stator (2) is fixed on this boss (4a), the output shaft (5) of described driving engine stretches in outer cover (3) and through stator (2) and is connected with rotor (1) from the centre hole of boss (4a), described rotor (1) is hood-like, described rotor (1) covers on outside stator (2), on the closed end of described outer cover (3), have skylight (7), the closed end of described rotor (1) is along being circumferentially distributed with through hole, on the aperture of through hole, be provided with fan leaf (6).
During installation, after stator, rotor are installed, on cover outer cover just can, easy for installation, easy to maintenance.Engine housing is connected with support and connection dish.Fan is contained in the closed end of outer cover, and the wind energy of fan enters generator from the skylight of outer cover, cooled electric generator inside, and wind can also enter from the closed end of rotor, in rotor, stator etc. is carried out cooling, good cooling results.Electrical generator is difficult for consume.
In technique scheme: install for convenient, be provided with sleeve (8) in the centre hole of described rotor (1), described sleeve (8) is sleeved on the output shaft (5) of driving engine.
In technique scheme: the closed end of described rotor (1) is along being circumferentially distributed with through hole, and described fan leaf (6) is arc flabellum, described fan leaf (6) one end is fixed on the other rotor (1) of through hole.
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, good cooling results, motor long service life is easy for installation.
