On the electric bicycle of extensive use, the buncher of rotary handle control has been installed, the speed regulating device of this buncher comprise alignment circuit and the speed regulation control mechanism that is installed on the rotary handle.Speed regulation control mechanism comprises magneto sensor in the shell, shell, with the fixing axle of shell be installed in the fan-shaped magnetic stripe that rotating handle, rotating handle on the axle point on shell one end and constitute.Magneto sensor is connected in the alignment circuit through lead, and alignment circuit is connected on the motor power-supply wire.
Summary of the invention
At above-mentioned deficiency, the utility model be exactly to provide a kind of can be by operating personnel's buncher under water of speed governing under water.
Buncher under water of the present utility model, comprise motor and speed regulating device, motor is installed in the can, handle is installed on the shell, said speed regulating device have alignment circuit and speed regulation control mechanism, said speed regulation control mechanism is installed on the handle, handle comprises axle and the rotary sleeve that is installed on the axle, one end of axle is equipped with the speed regulation control mechanism shell, being equipped with at axis on the end face of rotary sleeve sensing shell is the fan-shaped magnetic stripe at center, with the rotary sleeve end face magneto sensor is installed with interval in the shell, magneto sensor is connected in the alignment circuit through lead, alignment circuit is connected on the motor power-supply wire, and wherein an end of rotary sleeve sensing shell stretches in the shell, between axle and the rotary sleeve and between rotary sleeve and the shell sealing ring is installed all.
Compared with the prior art, buncher under water of the present utility model, owing to used in the rotary handle counterrotating magneto sensor and magnetic stripe through the speed of service of alignment circuit control motor, with sealing mechanism the speed regulation control mechanism in the rotary handle is isolated from the outside again, to realize underwater speed governing operation, make the underwater operation personnel can carry out the purpose of speed governing easily to motor.
Said motor is a brshless DC motor, and said alignment circuit comprises computer and power amplifier, and wherein the magneto sensor in the speed regulation control mechanism is connected on the input end and computer, and the output of power amplifier connects the power input of brshless DC motor.
The central angle of said fan-shaped magnetic stripe is 90 °, the magnetic field intensity that passes through equably from by force to weak, the magneto sensor of institute's adapted is Hall element or magnetic sensitive transistor.
