Embodiments for Carrying Out the Invention
[0009] The present invention will be described in detail with reference to the accompanying drawings so that other features, advantages, and achieved effects of the present invention can be clearly understood.
[0010] Referring to FIGS. 2 and 3, the present invention provides a mobile charging device capable of preventing a mobile communication device and a stand from falling.
[0011] The mobile charging device 1 includes a housing 11 and a storage battery 12, and the storage battery 12 is disposed inside the housing 11. Further, a first magnetic adsorption surface 111 and a second magnetic adsorption surface 112 are provided on the housing 11, and the storage battery 12 can be a solid-state battery. Different from a battery using a conventional liquid electrolyte, the solid-state battery is an advanced battery technology adopting a solid electrolyte. Different from the structure of a conventional lithium-ion battery, the greatest feature of the solid-state battery lies in conducting current using solid materials such as ceramics, polymers, and other solid chemical substances.
[0012] The stand 2 is installed on one side of the mobile charging device 1, and a third magnetic adsorption surface 211 is provided on the stand 2. When the mobile charging device 1 is attached to the stand 2, the second magnetic adsorption surface 112 and the third magnetic adsorption surface 211 are mutually adsorbed and fixed. The stand 2 is configured to include a main body 21 and legs 22. The main body 21 serves to support the mobile charging device 1, and the legs 22 are provided to support the main body 21 and maintain stability.
[0013] Referring to FIGS. 1 and 4, a mobile communication device 3 is installed on one side of the mobile charging device 1. The mobile communication device 3 is provided with a fourth magnetic adsorption surface 31. When the mobile communication device 3 is attached to the mobile charging device 1, the first magnetic adsorption surface 111 and the fourth magnetic adsorption surface 31 are mutually adsorbed and fixed. The first magnetic adsorption surface 111, the second magnetic adsorption surface 112, and the third magnetic adsorption surface 211 can be double-sided magnets. Also, the fourth magnetic adsorption surface 31 can be a double-sided magnet. A double-sided magnet is a magnet that has magnetic effects on both sides and, unlike conventional single-sided magnets, can generate magnetic forces on both surfaces. Therefore, it is suitable for applications that attract or repel ferromagnetic materials.
[0014] The mobile communication device 3 refers to an electronic device capable of performing wireless communication, usually having portability and supporting voice calls, data communication, and other communication functions. The mobile communication device 3 includes smartphones and tablets. In the actual use of this invention, the rechargeable battery 12 inside the mobile charging device 1 can store power during the charging process. When the mobile charging device 1 is connected to an external power source, the power of the external power source is sent to the mobile charging device 1 and stored in the rechargeable battery 12. When the rechargeable battery 12 is fully charged or has stored sufficient power, the mobile charging device 1 enters a standby state and prepares to supply power to the mobile communication device 3. The mobile charging device 1 is connected to the mobile communication device 3 via a connection cable and starts supplying power as needed. The mobile communication device 3 receives the power supplied from the mobile charging device 1, and the power is sent to the internal charging circuit of the mobile communication device 3. Thereafter, the power is stored in the internal battery of the mobile communication device 3. The mobile communication device 3 monitors the state of the internal battery and allows the charging process to proceed stably. When the internal battery is fully charged, the charging is automatically stopped to prevent overcharging.
[0015] Referring to FIGS. 1, 4, and 5, in this way, by using the first magnetic adsorption surface 111 and the second magnetic adsorption surface 112 of the mobile charging device 1, the mobile communication device 3 and the stand 2 can be adsorbed and fixed respectively, preventing the mobile communication device 3 from falling from the stand 2 due to contact.
[0016] Referring to FIGS. 6, 7, and 8, the charging process of the present invention can select either wireless charging or wired charging. As shown in FIGS. 6 and 7, in the wireless charging process, a power transmission coil 41 needs to be installed in the mobile charging device 1, and a power receiving coil 42 needs to be installed in the mobile communication device 3. When the mobile charging device 1 is activated, the storage battery 12 allows current to flow according to the terminal voltage and supplies current to the power transmission coil 41. According to Ampere's law, a magnetic field is generated around the power transmission coil 41, and the magnetic field changes with the change of the current, generating an alternating magnetic field. When the mobile communication device 3 is placed near the mobile charging device 1, the power receiving coil 42 senses the alternating magnetic field generated from the power transmission coil 41. Thereby, based on Faraday's law of electromagnetic induction, the power receiving coil 42 converts the alternating magnetic field into an alternating current. However, since the current generated by the power receiving coil 42 is an alternating current, a rectifying circuit inside the mobile communication device 3 converts this alternating current into a direct current. This is because the internal battery of the mobile communication device 3 usually needs to be charged with direct current.
[0017] In the wired charging process, as shown in FIG. 8, a first connection port 43 is provided in the mobile charging device 1, and a second connection port 44 is provided in the mobile communication device 3, and they are connected by a connection cable 45. When the mobile charging device 1 and the mobile communication device 3 are connected via the connection cable 45, the mobile charging device 1 activates the storage battery 12 and drives the current with the terminal voltage to supply power. The current flows from the first connection port 43 of the mobile charging device 1 through the connection cable 45 to the second connection port 44 of the mobile communication device 3. The connection cable 45 is responsible for transmitting the current from the mobile charging device 1 to the mobile communication device 3. When the current enters the second connection port 44 of the mobile communication device 3, the battery management system (Battery Management System, BMS) of the mobile communication device 3 guides the current to the internal battery, and the internal battery of the mobile communication device 3 stores the current from the mobile charging device 1. When the internal battery is fully charged, the battery management system of the mobile communication device 3 automatically stops the wired charging process. The content described above is only the best embodiment of the present invention and does not limit the scope of implementation of the present invention. Therefore, equivalent shape, structure, or combination changes made without departing from the spirit and scope of the present invention shall all be included in the claims of the present invention.
