Japan, Feb. 24 -- PANASONIC IP MANAGEMENT CORP has got intellectual property rights for 'MOTOR UNIT AND ELECTRIC BICYCLE.' Other related details are as follows:
Application Number: JP,2021-209883
Category (FI): B62J43/13,B62M6/50,B62M6/55
Stage: PROBLEM TO BE SOLVED: To provide a motor unit that can easily be reduced in the size of a case by reducing the width of the case and to provide an electric bicycle.SOLUTION: A motor unit 3 includes: a case 4; a motor 5 accommodated in the case 4 and having a motor rotation shaft 51 and a rotor 52 that rotates integrally with the motor rotation shaft 51; an input shaft 6; an output body 8; and a speed reduction mechanism 9. The input shaft 6 extends through the case 4 in the direction of the axis 600 and is disposed so as to be rotatable about the axis 600. The output body 8 extends through the case 4 in the direction of the axis 600 and is disposed so as to be rotatable about the axis 600. The speed reduction mechanism 9 is accommodated in the case 4, reduces the speed of rotation of the motor 5 and transmits the rotation to the output body 8. The speed reduction mechanism 9 includes a plurality of pairs (91, 92) of gears (911, 912; 921, 922) that mesh with each other. In at least one pair of the plurality of pairs of gears, respective central axes of rotations of the gears are orthogonal to each other.SELECTED DRAWING: Figure 3 (Grant)
