Description
Technical field
The present invention relates to the elimination of the non-foreign bodies detection type foreign matter of electric car wireless charging and deicing devices, can be achieved at the same time
Unattended electric car wireless charging current potential foreign matter is removed and two kinds of functions of ice-melt.
Background technique
For electric car wireless charging technology initially based on electromagnetic induction coupled modes, the starting of foreign study mechanism is more early,
As representative have Auckland, NZL university wave Boys professor headed by seminar.But due to induction type wireless power transmission
Technology is harsher to the design requirement of magnetic circuit, and transmission range is lower (mostly in cm range), therefore in current research just
Resonance type wireless charging modes are gradually magnetically coupled to be replaced.Domestic current research hotspot is concentrated mainly on theory analysis and closes
The two aspects of key equipment trial-production.The principle of electric car magnet coupled resonant type wireless charging is to pass through household 220V alternating current
Higher-order of oscillation power supply becomes high-frequency high-voltage, and by working under identical resonance frequency, transmitting coil constantly passes energy
Out, receiving coil receives energy, and by way of close coupling is isolated, loading coil draws energy, passes through rectifying and voltage-stabilizing device
It charges to batteries of electric automobile.
Currently, more and more scientists are to this skill with the continuous heating of electric car wireless charging technical research
Art gives enough affirmatives.But since wireless charging system transmission characteristic and job stability are affected by the external environment very
Greatly, therefore, more and more research institutions take up the research in foreign bodies detection and removing.And the precision of current foreign bodies detection
With means complex, and accuracy is not high, is usually done after detecting that foreign matter is located in charge position using what is artificially removed
Method increases the complexity of wireless charging operation management, and the target unattended with wireless charging is disagreed.Meanwhile ice and snow
Covering also by the stability of extreme influence wireless charging and charge coil positioning accuracy.Therefore, electric car wireless charging
The foreign matter of current potential is removed to be solved with ice-melt problems demand.The present invention is examined by the non-foreign matter designed for electric car wireless charging
Survey type foreign matter is eliminated and ice-melt integrated apparatus, may be implemented to realize that foreign matter is (living under conditions of not needing detection device for foreign matter
Body and metal chaff interferent) it eliminates with ice-melt snow function in one, there is good economy and practicability.

Drop screw rod is closely engaged by screw thread, is driven screw rod to carry out rotary lifting using external motor, is supported on non-crystalline material cover board
Charge position ground or more is risen to, centre rotational axis does the motive power of forward and reverse sliding as cover plate support sliding rail.
Sliding rail occlusion rotatable gear noose, can bidirectional rotary on the centre rotational axis of the Teflon telescope support
Turn and be engaged with cover plate support sliding rail rotation winding, drives the nonmetallic electric heating cover board opposite or mutually from operation.
The non-foreign bodies detection type foreign matter of the electric car wireless charging is eliminated and deicing device, it is characterised in that non-gold
Belong to electric heating cover board upper surface can short-term warming to 60 degree Celsius, it is ensured that the living body being attached on charge position non-crystalline material cover board is different
Object experiences burning heat sensation and avoids causing to scald to it again, to expel the organism being attached on cover board and reach the mesh of ice-melt snow
's；For other non-living body foreign matters, electric heating type non-crystalline material cover board is driven mutually from movement, to open lid by cover plate support sliding rail
Plate guarantees that foreign matter leaves the center charged area of wireless charging system for electric automobile, avoids bring charging performance unstable.
The non-foreign bodies detection type foreign matter of the electric car wireless charging is eliminated and deicing device, it is characterised in that can revolve
Turn lifting screw and centre rotational axis and drive rotation by two thread motors, rotatable lifting screw drives nonmetallic electric heating cover board
It need to be kept when rising to charge position ground or more cover plate closing state 2 ~ 3 seconds, guarantee living body foreign matter energy after experiencing burning heat sensation
Charged area is fled from time, then the centre rotational axis continuous rotation is driven to discharge the cover plate support sliding rail, centre rotational axis
Rotation angle it is equal with the ratio of sliding rail length and rotatable gear outer radius, it is ensured that traction electric machine worker thread prevents from sending out
Raw cover board opens that range is inadequate or forced motor stall and burns motor.
The utility model has the advantages that provided by the present invention for the elimination of non-foreign bodies detection type foreign matter and ice-melt of electric car wireless charging
Integrated apparatus, have the advantage that 1, principle is simple, operation with it is easy to control, may extend to the buried depth of different coils or
The wireless charging system for electric automobile that charge position region is not waited solves wireless charging system about foreign matter elimination and ice and snow substantially
The problem of covering；2, structure is simple, reliable for operation, and living body foreign matter is expelled to complement each other with melting of ice and snow step, clear rigorous, protects
System reliability of operation is demonstrate,proved；3, easy to implement, it is same that the foreign matter that this system is included, which is eliminated with ice-melt integrated apparatus,
Covering device is made of elemental devices such as hot type amorphous cover board, support sliding rail, Teflon telescope support, rotatable gears, ties
Structure is simultaneously uncomplicated, will not cause difficulty to building for system, therefore easy to implement；It 4, can be right with simple and convenient reliable method
Living body foreign matter is expelled, wireless charging central area is taken away to non-living body foreign matter, is melted to ice and snow, and foreign matter inspection is reduced
The complexity and operation cost with Attended mode are surveyed, in the environment of wireless charging technology is grown rapidly, which is met
Market needs have been closed, have been had a extensive future, foreign matter is eliminated simple, reliable with ice-melt snow control method.
