Specific embodiment
The design concept of the utility model are as follows: the closed type earphone charging storehouse for designing folding with convenience, by charge-discharge circuit and
Battery is integrated in warehouse, can be realized battery charging and discharging, and will be electrically charged earphone 4 and be coincide and be put into storehouse, real in charge and discharge
Existing electricity is shown.
It is illustrated below with reference to Fig. 1~3 pair the utility model structure.
Portable charge and discharge earphone storehouse described in the utility model, middle layer 3 and the assembling of lower case 2 are fixed together or one
It is body formed, charge-discharge circuit, battery are provided in the cavity that the two is surrounded.Electrical interface 6 is set on 2 side wall of lower case.
1 side of upper cover is flexibly connected with the side wall of the cavity, to turn on or off earphone storehouse.The mode of flexible connection
It can be common rotating shaft fixed type, be using shaft as axis rotation upper cover 1 when turning on or off earphone storehouse.Upper cover 1 is even
The opposite side of contact is provided with magnet.Upper cover 1 can be single layer structure or hollow structure.By inner cover and outer cover group when hollow structure
It fills, the space that inner cover and outer cover are surrounded can be put into the components such as magnet.
Middle layer 3 has following three effects: first is that isolation upper cover 1 and lower case 2, form cavity with lower case 2, accommodate
Charge-discharge circuit, battery；Second is that recessed formed in itself a part of region has 4 shape of earphone of coincideing, whole earphone obliquely
Rest area 5, and earphone rest area 5 is provided in the place for corresponding to 4 charging contacts of earphone for by electric discharge output thimble
Through-hole.The whole benefit designed obliquely is can to save space；Third is that being shown for carrying out electricity.
Earphone rest area 5 can be realized the firm placement and charging of earphone 4.Further, 5 bottom of earphone rest area is
Through-hole, the benefit being arranged in this way be can further downward extending space, avoid because being stored caused by earphone 4 is different in size empty
Between cannot be adaptive.More preferably, the region that upper cover 1 corresponds to earphone rest area 5 is recessed upwards.When upper cover 1 is hollow structure,
The region that its lower surface corresponds to earphone rest area 5 is recessed upwards.Design can further enhance earphone storehouse to 4 shape of earphone in this way
It is adaptive.
Magnet assemblies are additionally provided in the upper cover 1 and middle layer 3, to further realize between upper cover 1 and middle layer 3
Adsorption capacity, and then realize earphone storehouse entirety better sealing.The magnet assemblies include to be set to magnet and the centre of upper cover 1
The magnet of 3 corresponding position of layer, it is attracting between two magnet.Magnet can be set in surface or interlayer (when upper cover 1 and/or in
Interbed 3 can be arranged in interlayer when being hollow structure).
Charge-discharge circuit is illustrated below.
The charge-discharge circuit includes TYPE-C charging interface, charging pressure-boosting chip, MCU main control chip, output detection electricity
Road, charactron, USB electric discharge output interface, battery protecting circuit, electric discharge output thimble 8；Connection relationship are as follows: charging pressure-boosting chip
It is connect with TYPE-C charging interface, electric discharge output thimble, USB electric discharge output interface, battery, MCU main control chip；Electric discharge output top
Needle is connect with output detection circuit, and MCU main control chip is connect with charging pressure-boosting chip, charactron, soft-touch control 7, battery；Battery
It is connect with battery protecting circuit, soft-touch control 7.MCU main control chip is connect with soft-touch control 7, when receiving touch signal, just will
Information about power passes through numeral method.TYPE-C charging interface, USB electric discharge output interface are arranged in lower case 2.Especially
, TYPE-C charging interface is electrically connected with USB electric discharge output interface, in this way can not be by boost chip, directly in charging
USB electric discharge output interface electric discharge is given, is increased operation rate.It should be appreciated that then being risen by charging when TYPE-C charging interface does not charge
Pressure chip, which exports, gives electric discharge output interface.
In addition, it is necessary to explanation, a user has been built in the setting of MCU main control chip can according to need setting charge and discharge
The hardware platform of electric program setting, is not related to the improvement of method.
