Description
Technical field
The utility model relates to a kind of position indicator systems, can not need positioning mechanism in particular to one kind
Under, can the position of automatic detection wireless charging receiving end device whether offset, if offset can automatic prompt, and can reach
The cost and maintenance of positioning mechanism are saved, the wireless charging of the application suitable for various wireless charging receiving terminal devices positions instruction
System.
Background technique
To obtain optimal efficiency of transmission, the aerial position of transmitting terminal and receiving end cannot have too many inductive power supply
Offset, there are two types of the ways of previous wireless charging positioning:
1. limitation placement position is gone to realize transmitting terminal antenna and receiving end antenna in the way of the mechanical structure of transmitting terminal
Exactitude position, but a disadvantage is that cause the instrument size of receiving end to be limited by mechanism because of the reason of mechanism protrusion, it is too big
Equipment can not be put into mechanism restricted area, and too small equipment can make mechanism alignment mode lose effect, so what transmitting terminal can arrange in pairs or groups
Receiving device is limited by mechanism.
2. magnetic-type contraposition, this is the most-often used alignment mode of early stage wireless charging, transmitting terminal antenna and receiving end day
A magnet is all installed at line center, and explicitly defines the pole the N S extreme direction of transmitting terminal and receiving end, can be light using magnet suction type
Easily realize that the function of precisely aligning, magnetic-type disadvantage are that magnet is placed in antenna center and will cause efficiency of transmission reduction, and
And increase calorific value, power be more than after 10 watts calorific value may cause problem for security.
The utility model wireless charging position indicator system using inductance close to paramagnetic material or other inductive components,
Since the relationship of mutual inductance can allow the increased principle of inductance sensibility reciprocal can be automatic in wireless charging device transmitting terminal setting sensor
Whether detection wireless charging receiving end position offsets, if offsetting meeting automatic prompt, if prompting position normal without offset, this
Utility model is to can be widely used for the various receptions for supporting wireless charging specification (Qi) compared to the advantage of previous alignment mode
End device will not cause function not to be available because of mechanism is of different sizes, and can make for avoiding magnetic from being assemblied in antenna center
Efficiency of transmission decline, and magnet is allowed to overheat the problem of leading to safety.
It is all to be carried out using above-mentioned magnetic-type and linkage on existing technique of counterpoint, the utility model wireless charging
Sensibility reciprocal of the position indicator system system using detecting inductance, inductive drop, resonance frequency, the decaying modes such as damping curve realize, industry
Boundary and beyond example.
Utility model content
In view of existing positioning system there are still there is not perfect place, inventor's through a long time is constantly researched and developed, eventually
In develop it is such can in the case where not needing positioning mechanism, can the position of automatic detection wireless charging receiving end device whether have
Offset if offsetting meeting automatic prompt, and can reach the cost and maintenance for saving positioning mechanism, connect suitable for various wireless chargings
The wireless charging position indicator system of receiving end device.
The utility model wireless charging position indicator system, including a sensing inductance unit, connect to sense wireless charging
The inductance of receiving end device；One analysis circuit unit, is electrically connected, to be analyzed to identify sensing wireless charging with sensing inductance unit
Whether receiving end device position is appropriate；And a microprocessor unit, be electrically connected with analysis circuit unit, to analyzing circuit list
The data of member passback are judged, and issue indicating signal.
The utility model wireless charging position indicator system can be divided into sensing inductance unit, voltage analysis on circuit structure
Circuit unit and microprocessor unit are analyzed and issue indicating signal after circuit unit return data judges, without appointing in volume production
What problem.
The main purpose of the utility model wireless charging position indicator system is can be in the case where not needing positioning mechanism, can
Whether offset with the position of automatic detection wireless charging receiving end device, if offsetting meeting automatic prompt, and saving can be reached
The cost and maintenance of positioning mechanism, the application suitable for various wireless charging receiving terminal devices.
