Abstract
The utility model relates to a two signal output device of motor belongs to motor technical field, including motor rear end cover and output shaft, motor rear end cover is worn out to the rear end of output shaft, the rear end of output shaft is equipped with signal pickup assembly, motor rear end cover's back tip symmetry is equipped with two circuit boards, every circuit board direction outwards is provided with detection device, signal pickup assembly and two detection device link to each other, the utility model discloses a two signal output device of motor, every detection device can both export independent real -time pulse signal, and under the signal interruption's of the same kind condition, the signal can be continued to provide in another way, has strengthened the reliability of motor.
Description
Technical field
This utility model relates to a kind of motor possessing redundant backup function, particularly a kind of
It is applicable to electric motor car, possesses the dual signal output device of the motor of redundant backup function,
Belong to motor technology field.
Background technology
The double-wheel self-balancing electric motor car of current trend, it uses two wheel driving motors.
Motor is as directly driving and the executive component of control body gesture, the safety ten of itself
Divide important.Once motor catastrophic failure, double-wheel self-balancing electric motor car, by out of control, causes riding
Person is injured.Therefore, design a kind of motor possessing redundant backup function to avoid because of motor
The danger that catastrophic failure causes, the most necessary, wherein possess redundant backup function
Motor is necessarily required to a set of dual signal output device, increases the reliability of motor.
Utility model content
This utility model purpose is to provide a kind of motor double to overcome the deficiencies in the prior art
Signal output apparatus, two-way can export independent real-time pulse signal, in a road signal
In the case of Duan, another road can continue to provide signal, enhances the reliability of motor.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of motor is double
Signal output apparatus, including motor rear end plate and output shaft, the rear end of described output shaft passes
Motor rear end plate, the rear end of described output shaft is provided with signal pickup assembly；After described motor
The rearward end of end cap is arranged with two circuit boards；Described each circuit board direction outwardly is provided with
Detection device；Described signal pickup assembly and two detection devices are connected.
Preferably, described signal pickup assembly is grating coding disk.
Preferably, described detection device is photoelectric detection system.
Due to the utilization of technique scheme, this utility model compared with prior art has following
Advantage:
Motor dual signal output device of the present utility model, each detection device can export solely
Vertical real-time pulse signal, in the case of a road signal interruption, another road can continue to provide
Signal, enhances the reliability of motor.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of motor dual signal output device of the present utility model；
Wherein: 1, motor rear end plate；2, output shaft；3, signal pickup assembly；4, electricity
Road plate；5, detection device.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is made further the most specifically by specific embodiment
Bright.
Described in the utility model a kind of motor dual signal output device as shown in Figure 1,
Including motor rear end plate 1 and output shaft 2, after the rear end of described output shaft 2 passes motor
End cap 1, the rear end of described output shaft 2 is provided with signal pickup assembly 3；Described motor rear end plate
The rearward end of 1 is arranged with two circuit boards 4；Described each circuit board 4 direction outwardly is provided with
Detection device 5；Described signal pickup assembly 3 is connected with two detection devices 5.
Specific works principle is: signal pickup assembly 3 is with output shaft 2 rotating acquisition signal, inspection
Survey device 5 and detect the some pulse signals of output, by just calculating the number of output pulse per second
The rotating speed of current motor can be reflected.
Motor dual signal output device of the present utility model, each detection device can export solely
Vertical real-time pulse signal, in the case of a road signal interruption, another road can continue to provide
Signal, enhances the reliability of motor.
Concrete, described signal pickup assembly is grating coding disk, and described detection device is photoelectricity
Detection device, for highly preferred embodiment, using effect is the most optimal.
Below it is only concrete exemplary applications of the present utility model, to protection domain of the present utility model
Do not constitute any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed,
Within the scope of all falling within this utility model rights protection.
