Summary of the invention
The objective of the invention is in order to overcome the shortcoming and defect that prior art exists, and provide a kind of load-bearing capacity big, volume is little, and has the motor assembly of the electric seat of car of self-lock ability.
For realizing above-mentioned purpose; Technical scheme of the present invention is to include the motor and speed reducer structure, and this motor includes casing, main shaft, rotor, magnetic shoe, brush and commutator, it is characterized in that: stretch out outside the casing outer end of described main shaft; And the outer end of this main shaft is the double rotational directions worm screw; This double rotational directions worm screw is made up of two ends rotation direction opposite first worm screw and second worm screw, and described reducing gear includes the housing that is fixed in the casing upper end, and interior the rotation respectively corresponding to the both sides of double rotational directions worm screw of this housing is provided with a rotation axis; Be respectively first rotation axis and second rotation axis; Be linkedly set with first turbine that cooperates with first worm-drive on described first rotation axis, be linkedly set with second turbine that cooperates with second worm-drive on described second rotation axis, coaxial first pinion that is set with on described first turbine; Coaxial second pinion that is set with on said second turbine; The wheel of described first pinion and second pinion footpath is identical, and the gearratio of the gearratio of first turbine and first pinion and second turbine and second pinion is identical, in the described housing also rotation the seat adjustment driving shaft is set; Be linkedly set with gear wheel on this seat adjustment driving shaft, described gear wheel cooperates with first pinion and the second pinion transmission.
Through this setting, the double rotational directions worm screw is processed in an end of electric machine main shaft, be same axle, greatly reduced the volume of seat motor assembly.In addition, double rotational directions worm drive first turbine and second turbine rotate in the same way, then to drive first pinion and second pinion with rotating ratio; Utilize first pinion and second pinion to drive gear wheel again; Thereby drive the rotation of seat adjustment driving shaft, the adjusting of the front and back of realization seat position or the flip angle of backrest, the present invention's transmission design like this; Make motor have bigger load-bearing capacity; Actuating force is strong, and volume is little, most critical be that so design makes the mode of motor-driven seat adjustment driving shaft have the ability of self-locking completely.
Further being provided with is that described rotor includes by the multi-disc magnet steel and piles up the rotor core that forms, and this rotor core includes " worker " font frame of multiple tracks circumference uniform distribution, is provided with the skewed slot that tilts with respect to major axes orientation between adjacent " worker " font frame.Through this setting, increased the groove number of rotor core, make magnetic flux through rotor; Change gradual change into from sudden change; Make armature supply steadily can reduce the efficient of vibration and noise, having when seat adjustment is moved fully has very good stationarity, satisfies the requirement of low noise simultaneously again.
Further being provided with is that interlock is arranged with bipolar magnet ring on the described main shaft, also is provided with the Hall element that cooperates with magnet ring induction control in the said casing.Through this setting, can utilize Hall element to convert the rotational position signal of motor to signal of telecommunication output, this position signal of telecommunication is linked in the automobile inner control control system, realize the record and the key adjusting of seat position.
Further be provided with is that described housing is riveted about by loam cake and lower cover and formed.This riveted joint can be adopted tubular rivet.
It is big that the present invention has load-bearing capacity, and volume is little, and noise is low and have advantages such as self-lock ability.
Below in conjunction with Figure of description and embodiment the present invention is done further introduction.
