Detailed Description
In order to facilitate and simply understand the other features and advantages of the present invention and the effects achieved by the features and advantages, the present invention will be described in detail below with reference to the accompanying drawings:
referring to fig. 1, the present invention provides a built-in charging structure of a handheld electronic device, comprising: a hand-held electronic device, a coil 2 and a magnetic member 3.
The handheld electronic device is internally provided with a rechargeable battery 11 and an accommodating space 12. The handheld electronic device may be selected from a smart phone 100 (shown in fig. 1), a tablet pc 200 (shown in fig. 2), or a notebook pc 300 (shown in fig. 3), but is not limited thereto.
The coil 2 is disposed in the accommodating space 12 and electrically connected to the rechargeable battery 11. Specifically, a substrate 13 may be disposed in the accommodating space 12 of the handheld electronic device, and the coil 2 may be disposed on the substrate 13. The coil 2 may be a circular coil or a flat coil. Both ends of the coil 2 may be electrically connected to the rechargeable battery 11, respectively.
The magnetic member 3 is disposed in the coil 2, wherein when the magnetic member 3 and the coil 2 move relatively, the coil 2 is induced to generate electric power to charge the rechargeable battery 11. Specifically, the magnetic member 3 may be a round bar magnet or a flat bar magnet. The magnetic member 3 may be a permanent magnet. In practice, the two ends of the coil 2 may be closed, so that the magnetic member 3 is enclosed in the coil 2.
Referring to fig. 1 and 4, a switch 31 may be disposed between the coil 2 and the rechargeable battery 11, and in practice, pins of the switch 31 may be electrically connected to the coil 2 and the rechargeable battery 11, respectively, and the switch 31 is disposed on a housing of the handheld electronic device. A rectifying circuit 32, an amplifying circuit 33, a protecting circuit 34, or any combination thereof may be disposed between the coil 2 and the rechargeable battery 11. The switch 31 may be used to switch to an on state or an off state. When the switch 31 is switched to the on state, the coil 2 can be connected to the rechargeable battery 11, so that the power of the coil 2 can be charged to the rechargeable battery 11; on the other hand, when the switch 31 is switched to the off state, the electrical connection between the coil 2 and the rechargeable battery 11 is cut off, and the charging is disabled. The rectifier circuit 32 may convert alternating current to direct current. The amplifying circuit 33 can amplify the current flowing to the rechargeable battery 11. The protection circuit 34 can limit the magnitude of the current flowing to the rechargeable battery 11.
Referring to fig. 1 and 4, the handheld electronic device is taken as a smart phone 100, and a switch 31, a rectifying circuit 32, an amplifying circuit 33 and a protecting circuit 34 are disposed between the coil 2 and the rechargeable battery 11. When the switch 31 is switched to the on state for charging, the smart phone 100 is shaken, and as known from faraday's law of electromagnetic induction, the magnetic member 3 and the coil 2 generate relative motion, so that the magnetic field changes, i.e. the number of magnetic lines of force in unit area changes, the coil 2 generates induced electromotive force and induced current, the magnitude of the induced current is proportional to the rate of change of the magnetic field in the coil 2, i.e. the magnetic member 3 is proportional to the rate of relative motion of the coil 2. The induced current (ac) is converted into dc by the rectifying circuit 32, amplified by the amplifying circuit 33, and the protection circuit 34 limits the current flowing to the rechargeable battery 11, and finally, the dc is supplied to the rechargeable battery 11 to complete charging. The user can watch whether the battery power displayed on the screen of the smart phone 100 is full, and if so, the switch 31 is switched to the off state, so that the electrical connection between the coil 2 and the rechargeable battery 11 is cut off, and the charging cannot be continued. Similarly, the tablet pc 200 and the notebook pc 300 operate according to the same operation principle, and thus will not be described in detail.
Therefore, the invention charges the rechargeable battery by means of electromagnetic induction, the coil 2 and the magnetic element 3 are arranged in the accommodating space 12 at one side of the rechargeable battery 11, the coil 2 and the magnetic element 3 can be miniaturized (i.e. a miniature magnet is matched with an integrated circuit), the induced current is amplified by the amplifying circuit 33 to provide enough current quantity, the purpose of built-in charging is realized, the charging wire and the charger are not required to be carried when the rechargeable battery is out, and the battery is not required to be replaced frequently, thereby saving resources and avoiding environmental pollution caused by discarding the battery.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention; changes in form, construction, or combination thereof may be made without departing from the spirit and scope of the invention as defined in the appended claims.
