Description
Technical field
The present invention relates to motor technology field, particularly relate to a kind of electronic device.
Background technology
Existing motor generates heat because of the copper loss of stator iron loss or stator coil in operation process, electric tools is ready for use on stator heat is distributed to housing or extraneous air.
In order to make consequent heat distribute as early as possible, prior art adopts heat radiation interlayer, but heat radiation interlayer Long-Time Service, the elasticity of heat radiation interlayer can be reduced, cause the adhesion of heat radiation interlayer and housing thus, cause radiating effect poor.
Summary of the invention
The present invention by providing a kind of electronic device, and then improves the radiating effect of electronic device.
In order to solve the problems of the technologies described above, the technical scheme of the embodiment of the present invention is as follows:
A kind of electronic device, comprising:
Annular stator, described annular stator comprises the multiple teeth along arc surface, and described multiple tooth is wound with coil;
Described coil comprises first group of coil and second group of coil, and first group of coil is configured to the first sub-motor, and described second group of coil is configured to the second sub-motor;
Rotor, the arc surface being arranged on annular stator is inner;
Controller, connects described first group of coil and described second group of coil, for providing different current values for described first group of coil and second group of coil;
Housing, is coated on outside described annular stator and rotor, is provided with slide rail on the housing;
Transducer, described sensor setting is in described inner walls;
Heat abstractor, described heat abstractor comprises the pulley, the radiator fan that agree with described slide rail;
Drive unit, described drive unit connecting sensor and described heat abstractor.
Further, described slide rail can be and arranges in the shape of a spiral along described housing exterior walls, or arranges in irregular circuit.
Further, be connected by magnet absorption between described pulley with described slide rail.
Further, described transducer is net distribution in described inner walls.
The one or more technical schemes provided in the embodiment of the present invention, at least have following technique effect or advantage:
Owing to adopting in this electronic device, transducer is set at case inside, in hull outside, slide rail is set, the pulley of heat abstractor agrees with mutually with this slide rail, drive unit connecting sensor and heat abstractor, the temperature information that can detect according to transducer, dispelling the heat in the place that drive unit drives heat abstractor to reach temperature higher, effectively improves radiating effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of electronic device in the embodiment of the present invention;
Fig. 2 is the structural representation of the slide rail that embodiment of the present invention middle shell is arranged.
Embodiment
The embodiment of the present invention by providing a kind of electronic device, and then improves the radiating effect of motor.
In order to solve the problems of the technologies described above, below in conjunction with Figure of description and concrete execution mode, technique scheme is described in detail.
Embodiments provide a kind of electronic device, as Fig. 1, shown in Fig. 2, comprise: annular stator 10, rotor 20, controller 30, housing 40, transducer 50, heat abstractor 60, drive unit 70, this annular stator 10 comprises multiple teeth 101 of arc surface, described multiple tooth is wound with coil, concrete, this coil comprises first group of coil 1011 and second group of coil 1012, this first group of coil 1011 is configured to the first sub-motor, and second group of coil 1012 is configured to the second sub-motor.The arc surface that rotor 20 is arranged on annular stator 10 is inner.
Like this, divided by this electronic device in order to multiple sub-motor, first group of coil 1011 is independent of second group of coil 1012.
Therefore, the controller 30 of this electronic device connects this first group of coil 1011 and second group of coil 1012, for providing different current values for this first group of coil 1011 and second group of coil 1012, because the position at this first group of coil 1011 and second group of coil 1012 place may be different, therefore, make to be positioned at rotor 20, the heat that housing 40 outside annular stator 10 produces is also different, therefore, this housing 40 is provided with slide rail 401, this housing 40 inwall is provided with transducer 402, this transducer 402 is net distribution at this housing 40 inwall, like this, this transducer 402 just can detect that the temperature of concrete which inner position is higher.Because this slide rail 401 is arranged on housing 40, to slide rail being provided with heat abstractor 60, this heat abstractor 60 comprises the pulley agreed with this slide rail 401, and the radiator fan on pulley, specifically be connected by magnet absorption between this slide rail 401 with this pulley, such pulley can slide freely on this slide rail 401, also can not fall down.Particularly, this drive unit 70 connecting sensor 50 and heat abstractor 60, when transducer 50 detects that certain spot temperature is higher, drive unit 70 drives this heat abstractor 60 to arrive the position of this temperature drift along slide rail 401, dispels the heat for this region.Effectively improve radiating effect.This slide rail 401 can arrange in the shape of a spiral along this housing exterior walls or become irregular circuit to arrange, and makes heat abstractor 60 can arrive the different parts of housing 40 along this slide rail 401, carries out efficiently radiates heat.
Although describe the preferred embodiments of the present invention, those skilled in the art once obtain the basic creative concept of cicada, then can make other change and amendment to these embodiments.So claims are intended to be interpreted as comprising preferred embodiment and falling into all changes and the amendment of the scope of the invention.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
