Integrated interactive torque sensor motor

Abstract

The invention discloses an integrated interactive torque sensor motor which is characterized in that a torsion sensing seat is provided with a ratchet flywheel; a hollow cavity arranged at one side of a motor casing contains a movable torsion sensing slip ring assembly with magnetic steel and then is sealed with the torsion sensing seat, a torsion sensing slip ring in the torsion sensing slip ring assembly and the torsion sensing seat are cooperated dynamically; an annular groove and an upright post are arranged on an annular bulge forming the hollow cavity, the upright post is arranged at one end of a locating slot arranged on the torsion sensing seat, a spring matched with the shape of the annular groove is also arranged in the locating slot, the torsion sensing seat at the annular bulge rotates around a motor shaft so as to drive the torsion sensing slip ring assembly to move; a magnet steel is in magnetic induction cooperation with a Hall element, thereby outputting an electric signal so as to control the boosting rotation of a vehicle. In the integrated interactive torque sensor motor provided by the invention, Hall sensor components are all arranged on the motor casing, the conflict of occupying space due to function arrangement is solved, and an obvious magnetic induction effect is realized.

Description

Technical field [0001] The invention relates to the field of electric power assist transmission of vehicles, in particular to the structure of a bicycle electric assist sensor motor. Background technique [0002] In the field of bicycle electric-assisted sensors, Chinese invention patent application 201110125438.9 discloses a "structure of an electric-assisted sensor matched with a bicycle rear fork". A groove is provided at the bottom of one side of the bicycle rear fork and is fixed in the groove. A circuit board mounted with Hall elements is provided, and a sensor assembly on the rear axle passing through a long slot at the bottom of the groove is also accommodated in the groove. A permanent magnet and the sensor assembly are arranged on the sensor assembly. The Hall element on the circuit board is matched with magnetic induction; because the rear axle is restricted to move in the long slot at the bottom of the groove, therefore, when the rear axle moves, the permanent magnet ...

[0002] In the field of bicycle electric power-assisted sensors, Chinese invention patent application 201110125438.9 discloses a "structure of electric power-assisted sensors that cooperate with bicycle rear forks". A circuit board equipped with a Hall element is arranged, and a sensor assembly on the rear axle that passes through the long slot hole at the bottom of the groove and is movable is accommodated in the groove, and a permanent magnet arranged on the sensor assembly is connected to the The Hall element on the circuit board is magnetically coupled; because the rear shaft is limited to move in the long slot hole at the bottom of the groove, when the rear shaft is used to move, the gap between the permanent magnet relatively fixed to the rear shaft and the Hall element The magnetic induction changes, and the electric signal is output to control the afterburner rotation of the bicycle motor; the Hall sensor of this structure adopts a mechanical setting method, and its working principle is to generate acceleration when the vehicle is riding, which is obtained by the Hall sensor which is set separately from the motor. The power is converted into an electrical signal, which is used to drive the motor for afterburner driving; obviously, the motor and the Hall sensor given by this structure are set separately, relatively speaking, the reliability of the sensing signal is reduced, and the production process is relatively complex. Many, increase the production cost, make its scope of use limited, so it is urgent to design a new type of motor combined with the Hall sensor to meet the various needs of the market
