Detailed description of the invention
As Figure 1-4, a kind of electric vehicle motor electric shift mechanism, including motor power shaft 1, reducing gear 2 and power take-off mechanism 3, described reducing gear 2 arranges a set of shifter 5, shifter 5 includes gear shift tooth axle 51, lazy-tongs 52 and claw 53, the driving means 6 of shifter 5 it is additionally provided with on described reducing gear 2, described driving means 6 includes direct current generator 61 and drive mechanism 62, the input of drive mechanism 62 is connected with the outfan of direct current generator 1, the outfan of drive mechanism 62 is provided with driver chuck 63, driver chuck 63 coordinates with the dead man 55 on lazy-tongs 52；Described drive mechanism 62 is worm type of reduction gearing, and worm screw 621 is connected to the outfan of direct current generator 61, and described driver chuck 63 fixes the lower end of worm gear 622, and driver chuck 63 arranges cylinder mouth 65, in the end accommodation cylinder mouth 65 of described dead man 55；Described direct current generator 61 is connected with the main controller circuit of electric vehicle motor, shift change controller and motor working condition acquiring unit is had additional inside described master controller, motor working condition acquiring unit is for the various signal of telecommunication of output of Real-time Collection master controller, and shift change controller is connected with described direct current generator circuit.
This utility model is additionally arranged shift change controller and motor working condition acquiring unit inside the master controller of electric vehicle motor, working condition acquiring unit exports the various signals of telecommunication such as the electric current to mair motor and voltage for Real-time Collection master controller, and judge electrodynamic running status by the signal of telecommunication collected is analyzed, the result of analysis is fed back to the control unit of master controller, control unit decides whether to trigger shift change controller according to analysis result, once trigger shift change controller, shift change controller will drive direct current generator work, thus worm type of reduction gearing changes claw and gear shift tooth shaft position relation by lazy-tongs, thus realize gear shift；This utility model realizes electric gear without hand shift, the driving means of shifter by direct current generator, and concrete structure is reasonable, easy to use, safe and reliable feature.
Additionally this utility model also provides for a kind of manual/automatic integrated shifter, is also in series with shift control switch on the shift change controller connection circuit with described direct current generator；Described shift control switch is a comparison circuit；During use, when the feedback signal that motor working condition acquiring unit gathers, the control unit of master controller triggers shift change controller and sends shift command, the level signal of shift change controller is through shift control switch, need just can be sent to direct current generator consistent with the level signal residing for shift control switch, otherwise can not send shift command；So only have the shift command that sends of master controller could realize gear shift time consistent with the gear residing for shift control switch；But when shift control switch is in high tap position, to main control detect that electric motor car mair motor operating mode needs at once to switch to low-grade location time, in order to protect motor, extend the service life of motor, master controller can switch to low-grade location from high tap position automatically；This utility model is by shift control switch and master controller dual gearshift control mode; go out and the purpose of protection electric motor car mair motor; hand shift is designed like the gear changing mode that automobile manual-automatic integrated change speed gear box is manual by this utility model, can control upshift and can not control downshift；This utility model is in series with shift control switch between shift change controller and direct current generator, adds drivers and actively controls the selection switch of mair motor working condition, adds the initiative in driving process.
