Description

Cell-phone cover

Technical field

The utility model relates to a kind of cell-phone covers, more particularly to a kind of cell-phone cover of contact wireless charger.

Background technique

Currently, the charging modes of the digital products such as mobile phone, mobile power source are broadly divided into line charge and two kinds of wireless charging, middle line Filling is to be connect between charger and mobile phone (or mobile power source) with charging cable, its advantage is that charge efficiency is high, but disadvantage is each The charging plug of charging cable end must be inserted into mobile phone when use, be extracted again after charging, it is inconvenient to use；Wireless charging Charging cable when being to remove charging between mobile phone (or mobile power source) and charger and the charging scheme released, such as at present More popular electromagnetic induction (such as QI standard) wireless charging on the market, principle are that setting can be several nearby in charger The transmitting coil that alternating electromagnetic field is generated in cm range, is arranged receiving coil and rectification, filtering, control circuit in mobile phone, The electromagnetic induction for the alternating magnetic field that receiving coil when charging in mobile phone is generated by transmitting coil and electricity is generated in receiving coil Gesture can charge to the battery in mobile phone after rectified, filtering.Existing this mobile phone electromagnetic induction charged scheme makes Used time, although between charger and mobile phone without charging cable connect, there are at high cost, charge efficiency is low, built in mobile phone The disadvantages of receiving coil fever causes mobile phone entirety temperature rise excessively high.

Summary of the invention

Purpose of the utility model is to solve at high cost, hairs present in the charging of existing mobile phone short distance electromagnetic wireless The big problem of heat, and provide it is a kind of it is at low cost, calorific value is small, the cell-phone cover of contact wireless charger easy to use.

Purpose of the utility model is realized as follows: a kind of cell-phone cover, the plastic body including being equipped with mobile phone accommodating cavity, It is convex equipped with the positive input electrode of mobile phone and the first lug boss of negative input electrode described in face respectively and second in the accommodating cavity The surface of the portion of rising, first lug boss and second lug boss has been covered each by positive conductive film and negative conductive film, institute The intersection extended respectively on the downside of the ontology between the ontology outer bottom on the outside of positive and negative conductive film is stated, it is described The outside of positive and negative conductive film matches with the positive and negative output electrode on charging rack respectively.Mobile phone is packed into the ontology when use Accommodating cavity in, positive and negative conductive film is located at surface and the second lug boss of the first lug boss under the elastic force effect of plastic body Surface tightly suppress the positive and negative input electrode on mobile phone respectively, the cell-phone cover after being loaded into mobile phone again at this time is put into charging rack On, the electric power on charging rack in positive and negative output electrode is transported on mobile phone by the positive and negative conductive film on ontology respectively It is sent into mobile phone after positive and negative input electrode and charges to rechargeable battery.

The positive and negative conductive film is the electrodeposition of metals being electroplated in the body surface；The electrodeposition of metals can be Parcel plating is carried out using more universal plastic electroplating technique using current, first can also coat one in ontology corresponding position Water power plating is carried out after layer conductive paint again, latter electro-plating method is equipped with one namely between the electrodeposition of metals and the ontology Layer conductive paint.

The positive and negative conductive film is the conductive paint coated in the body surface.

The conductive paint is conductive silver paint or conductive copper paint or conductive carbon black.

Positive input electrode and negative input electrode on the mobile phone are separately positioned on the back of the mobile phone or are arranged in institute State the back of mobile phone and the intersection of downside.

Due to using technical solution described in the utility model, the cell-phone cover after being packed into mobile phone is placed directly in mobile phone charging It can be realized on frame and contact wireless charging carried out to mobile phone, there is no electromagnetic coil using the convenience and this charging modes of pole Fever, charge efficiency and charging current and directly fill it is the same, at low cost, calorific value compared with electromagnetic type wireless charging scheme Small advantage.
