Description
Technical field
The utility model relates to a kind of electric bicycle motor, particularly a kind of motor of electric bicycle of the gear reduction type that is built-in with torque sensor and velocity transducer.
Background technology
With manpower is main kinetic energy and the electric bicycle that is aided with motor kinetic energy, when running into situations such as upward slope, need be aided with more motor kinetic energy and save manpower.This situation needs controller to control motor provides more kinetic energy.This function is that controller is finished according to the information of torque sensor.
And existing torque sensor is arranged on the pedal mechanism substantially.And for the sake of security, a lot of electric bicycles also need non-zero starting, and this just needs velocity transducer.And existing velocity transducer also is arranged in pedal or the rotating shaft.Velocity transducer of the prior art and torque sensor all be and motor split setting, caused electrical structure complexity, complete vehicle weight bigger like this, and operating sensor is not very reliable.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome above-mentioned weak point, a kind of motor of gear reduction type electric bicycle to be provided, and it is built-in with torque sensor and velocity transducer.
Goal of the invention of the present utility model is achieved through the following technical solutions.
A kind of electric bicycle motor that is built-in with the gear reduction type of torque sensor, this motor is a profile formula motor, comprise rotation profile, stator, rotor, motor shaft, reduction gearing etc., also be provided with torque sensor in the motor, this torque sensor comprise be arranged in the rotation profile end face and and rotation profile between can corresponding rotation the moment swivel base, be provided with the spring steel ring that has breach between moment swivel base and the profile end face, in the middle of the described moment swivel base is dead eye, motor shaft passes from this dead eye, moment swivel base outer face connects sprocket wheel, the two ends of the breach of described spring steel ring, one end horizontal level height, other end horizontal level is low, breach one end of described spring steel ring is connected with the profile end face by contiguous block, the other end is connected with the moment swivel base by another contiguous block, is provided with a circle magnet steel on described rotation profile inner face and the moment swivel base inner face respectively uniformly, and described stator is provided with two hall devices.
Also be provided with velocity transducer in the above-mentioned motor, it is made up of with the Hall element that is arranged on the stator the circle of one on rotation profile magnet steel.
The beneficial effects of the utility model are: all built-in and motor internal of torque sensor and velocity transducer, electrical structure has simply alleviated complete vehicle weight, has also improved the stability of the transmission of torque signals and rate signal greatly.

Embodiment
Below in conjunction with the description of drawings specific embodiment of the utility model.
Present embodiment as shown in Figure 1, motor (1) comprising: rotation profile (2), movement (3), motor shaft (8), reduction gearing (9), wherein movement (2) has comprised stator and rotor, reduction gearing (9) is a planetary gear.
Rotation profile as shown in Figure 2 (2), be provided with in its end face can corresponding rotation with it moment swivel base (4), be provided with the spring steel ring (5) that has breach between moment swivel base and the profile end face.
In the middle of the moment swivel base (4) as shown in Figure 6 is dead eye (42), and motor shaft (8) passes from this dead eye, and the edge of this moment swivel base (4) has an extrusion position to be provided with connecting hole (41).Moment swivel base outer face connects the sprocket wheel of electric motor car.
As Fig. 3, Fig. 4, spring steel ring shown in Figure 5, the two ends of its breach, one end horizontal level height, other end horizontal level is low, all be provided with connecting hole (51) on the two ends, the connecting hole (51) of breach one end of described spring steel ring is connected with the connecting hole (21) of profile end face by contiguous block, the connecting hole (51) of the breach other end of spring steel ring is connected with the connecting hole (41) of moment swivel base (4) by another contiguous block, the rotation profile inner face is provided with a circle magnet steel (6), moment swivel base inner face is provided with a circle magnet steel (61), and described stator is provided with two hall devices (7).
When manpower acts on pedal, moment is sent to moment swivel base (4) by sprocket wheel, on spring steel ring (5) and the rotation profile (2), spring steel ring this moment (5) is compressed, produced angular displacement between moment swivel base (4) and the rotation profile (2), this angular displacement can be measured according to the relative angular displacement between the magnet steel (6) on magnet steel on the moment swivel base (61) and the rotation profile by two hall devices (7) that are arranged on the motor stator, this angular displacement is directly proportional with moment on the pedal, thereby draw the signal of telecommunication that is directly proportional with torque by hall signal and controller processing, finished moment sensing.On the rotation profile one circle magnet steel (6) and the velocity transducer that is arranged on Hall element (7) composition on the stator can rotate the speed pulse signal that output is directly proportional with rotating speed according to motor.
