Detailed ways

FIG. 1 is a schematic diagram of an electronic device according to an embodiment of the invention. Please refer to FIG. 1 , the electronic device 100 of this embodiment includes a power controller 120 and a motor 130 capable of generating electricity. The power controller 120 is used for electrically connecting an energy storage device 50 . The electronic device 100 of this embodiment may further include a circuit module 110 . When the electronic device 100 is a notebook computer, the circuit module 110 is, for example, a computer module. However, the electronic device in other embodiments of the present invention may also be a tablet computer, a mobile phone or other electronic devices. The power controller 120 can obtain the power required for the operation of the electronic device 100 from the energy storage device 50 and distribute it to various components of the electronic device 100 , but the electronic device 100 may also directly use an external power source without using the energy storage device 50 .

FIG. 2 is a partial exploded view of the generating motor of FIG. 1 , and FIG. 3 is a circuit diagram of the electronic device of FIG. 1 . Please refer to FIG. 2 and FIG. 3 , the generator motor 130 includes a magnetic part 134 and a coil part 136 . The generator-generating motor 130 in this embodiment is an example in which a fan blade 132 is connected, but the generator-generating motor 130 may also be any motor used for other purposes in the electronic device 100 . The fan blade 132 in this embodiment is fixed to the magnetic part 134 , but the fan blade in other embodiments may also be fixed to the coil part. In other words, the magnetic part 134 of this embodiment is a rotor, and the coil part 136 is a stator. Therefore, the fan blade 132 fixed to the magnetic part 134 can generate airflow with the rotation of the magnetic part 134 . In other embodiments, the coil part can also be designed as a rotor, the magnetic part can be designed as a stator, and the fan blade can be fixedly connected to the coil part to generate airflow with the rotation of the magnetic part. The coil part 136 has a main coil C12 and a magnetic induction coil C14 electrically connected to the power controller 120 . When the current is passed to the main coil C12, the magnetic field generated by the main coil C12 and the magnetic field of the magnetic part 134 will interact, and then drive the relative rotation between the magnetic part 134 and the coil part 136, so as to drive the fan blade 132 to generate air flow to the circuit Module 110 dissipates heat. When the magnetic part 134 and the coil part 136 rotate relative to each other, the magnetic field of the magnetic part 134 induced by the magnetic induction coil C14 on the coil part 136 will have a change in strength and direction, and therefore generate electric energy on the magnetic induction coil C14 . The electric energy generated by the magnetic induction coil C14 is charged into the energy storage device 50 through the power controller 120 , which conforms to the current environmental protection trend of energy saving and carbon reduction.

The power controller 120 of this embodiment includes a rectifier 122 and a power management chip 124 . The main coil C12 is electrically connected to the power management chip 124 . The main coil C12 of this embodiment is electrically connected to the power management chip 124 of the power controller 120 via the circuit module 110 . The magnetic induction coil C14 is electrically connected to the rectifier 122 . The rectifier 122 is electrically connected to the power management chip 124 . The electric energy generated by the magnetic induction coil C14 is usually in the form of alternating current and the magnitude of the current is not constant. Therefore, it needs to be boosted and stabilized by the rectifier 122 before being supplied to the power management chip 124 . The power management chip 124 is used to electrically connect the energy storage device 50 . The energy storage device 50 is, for example, a rechargeable battery. The energy storage device 50 is an accessory of the electronic device 100 , but the electronic device 100 without the energy storage device 50 still belongs to the protection scope of the present invention. At present, the energy storage device 50 on the market has relatively complex specifications for the charging procedure, so the power management chip 124 needs to control the charging procedure to ensure the ideal charging of the energy storage device 50 . For example, the power management chip 124 controls to charge the energy storage device 50 with a constant current at the initial stage of charging. After the output voltage of the energy storage device 50 stabilizes to a preset value, the power management chip 124 controls to continue charging the energy storage device 50 at a constant voltage.

Please refer to FIG. 1 and FIG. 3 , the electronic device 100 of this embodiment may further include a protection circuit 140 electrically connected to the power controller 120 and the motor 130 capable of generating electricity. The function of the protection circuit 140 is to disconnect the electrical connection between the power controller 120 and the magnetic induction coil C14 of the generating motor 130 before the power controller 120 is overloaded. Alternatively, the protection circuit 140 can also limit the amount of electric energy output from the magnetic induction coil C14 to the power controller 120 before the power controller 120 is overloaded. For example, the protection circuit 140 can control the voltage value or current value of the electric energy output from the magnetic induction coil C14 to the power controller 120 to be below a threshold value. In order to prevent the power controller 120 from being overloaded and burned due to excessive electric energy generated by the generator motor 130 , the protection circuit 140 is used to protect the power controller 120 which is expensive and affects the operation of other components.

FIG. 4 is a schematic diagram of an electric generating motor of an electronic device according to another embodiment of the present invention. Please refer to FIG. 4 , the generator-generating motor 200 used in the electronic device of this embodiment can generate electricity as well as the generator-generating motor in the previous embodiment, the difference is that the generator-generating motor 200 of this embodiment does not have a fan blade but has an eccentric The device 210 is fixed to the coil part 220. The relative rotation between the magnetic part 230 and the coil part 220 drives the eccentric 210 to rotate to generate vibration. In other embodiments, the eccentric can also be affixed to the magnetic part.

To sum up, the electric generating motor of the electronic device of the present invention has a magnetoelectric induction coil that can induce a magnetic field to generate electric energy. Therefore, when the electric generating motor performs necessary operation, it can synchronously induce the magnetic field of the magnetic part to generate electric energy. In this way, the electric energy stored in the energy storage device can be increased to prolong the use time of the electronic device, and the environmental protection purpose of energy saving and carbon reduction can be achieved. The design of recovering electric energy to prolong the use time of the electronic device may provide very important assistance to the user of the electronic device at a critical moment.

Anyone skilled in the art can make some modifications and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention should be defined by the appended claims.
