Description

Technical Field

[0001] This utility model relates to a mobile charging device, and more particularly to a mobile charging device that can prevent mobile communication devices from falling off their support frames. Background Technology

[0002] A portable charging device (also known as a power bank) is a portable battery device designed to provide charging services anytime, anywhere for mobile communication devices such as smartphones, tablets, and laptops.

[0003] For example, a "portable power supply device" in Taiwan Patent No. TWM461242 includes a control circuit board disposed inside the portable power supply and a first power output port, a second power output port, a light-emitting module, and a power input port disposed on the portable power supply and electrically connected to the control circuit board. The control circuit board is further provided with at least one battery module, and the output current of the first power output port is greater than the output current of the second power output port.

[0004] However, when conventional power bank devices are used in mobile communication devices (such as smartphones), if the power bank is charging the mobile communication device, accidental contact with the mobile communication device may cause the device to fall and be damaged.

[0005] Therefore, how to improve the aforementioned deficiencies is the technical challenge that the designer of this case wants to solve. Utility Model Content

[0006] Therefore, in view of the conventional design, the purpose of this utility model is to solve and improve the problems and deficiencies of the conventional design, and to provide a mobile charging device that can prevent mobile communication devices and support frames from falling.

[0007] To achieve the above objectives, this utility model provides a mobile charging device that can prevent mobile communication devices from falling off their support frames. The device includes: a mobile charging device comprising a housing and a storage battery, the storage battery being disposed inside the housing, and the housing having a first magnetic surface and a second magnetic surface; and a support frame disposed on one side of the mobile charging device, the support frame having a third magnetic surface, wherein when the mobile charging device is attached to the support frame, the second magnetic surface and the third magnetic surface are attracted and fixed together.

[0008] One side of the mobile charging device is equipped with a mobile communication device, which has a fourth magnetic surface. When the mobile communication device is attached to the mobile charging device, the first magnetic surface and the fourth magnetic surface attract and fix each other.

[0009] The energy storage battery is a solid-state battery.

Detailed Implementation

[0021] To facilitate a concise understanding of the other features, advantages, and effects of this utility model, the following detailed description, in conjunction with the accompanying drawings, is provided:

[0022] Please see Figure 2 and Figure 3As shown, this utility model provides a mobile charging device that can prevent mobile communication devices from falling off their support frames, comprising:

[0023] A portable charging device 1 includes a housing 11 and an energy storage battery 12. The energy storage battery 12 is disposed inside the housing 11, and the housing 11 has a first magnetic surface 111 and a second magnetic surface 112. The energy storage battery 12 can be a solid-state battery. Solid-state batteries are an advanced battery technology that uses a solid electrolyte to replace the liquid electrolyte used in traditional liquid batteries. The structure of solid-state batteries differs from that of traditional lithium-ion batteries; the core difference lies in the use of solid materials (such as ceramics, polymers, or other solid chemicals) to conduct current.

[0024] A support frame 2 is disposed on one side of the portable charging device 1, and the support frame 2 is provided with a third magnetic surface 211. When the portable charging device 1 is attached to the support frame 2, the second magnetic surface 112 and the third magnetic surface 211 are attracted and fixed to each other. The support frame 2 may include a body 21 and a leg 22. The body 21 of the support frame 2 can be used to support the portable charging device 1, and the leg 22 supports the body 21 to maintain the stability of the body 21.

[0025] Please see Figure 1 and Figure 4 As shown, a mobile communication device 3 is provided on one side of the mobile charging device 1. The mobile communication device 3 has a fourth magnetic surface 31. When the mobile communication device 3 is attached to the mobile charging device 1, the first magnetic surface 111 and the fourth magnetic surface 31 are attracted and fixed to each other. The first magnetic surface 111, the second magnetic surface 112, and the third magnetic surface 211 can be double-sided magnets. The fourth magnetic surface 31 can also be a double-sided magnet. A double-sided magnet is a magnet that can exert magnetic force on both sides. Unlike traditional single-sided magnets, double-sided magnets have magnetism on both surfaces and can be used to attract or repel ferromagnetic materials.

[0026] The mobile communication device 3 refers to an electronic device capable of wireless communication, which is typically mobile and can support voice calls, data transmission, and other communication functions. The mobile communication device 3 may include smartphones and tablets.

[0027] In practical use, the energy storage battery 12 inside the mobile charging device 1 stores electrical energy during the charging process. When the mobile charging device 1 is connected to an external power source, the electrical energy from the external power source is sent to the mobile charging device 1 and stored in the energy storage battery 12. When the energy storage battery 12 of the mobile charging device 1 is full or has sufficient electrical energy, the mobile charging device 1 will enter a standby state, ready to supply power to the mobile communication device 3. The mobile charging device 1 can be connected to the mobile communication device 3 via a connecting cable. The mobile charging device 1 will start transmitting electrical energy to the mobile communication device 3 as needed. The mobile communication device 3 receives the electrical energy from the mobile charging device 1, and the electrical energy enters the internal charging circuit of the mobile communication device 3. The mobile communication device 3 will store the electrical energy in its internal battery. The mobile communication device 3 will monitor the status of the internal battery and ensure that the charging process proceeds smoothly. Once the internal battery is fully charged, charging will stop to prevent overcharging.

[0028] Please see Figure 1 , Figure 4 and Figure 5 As shown, the mobile charging device 1 uses its first magnetic surface 111 and second magnetic surface 112 to attach and fix the mobile communication device 3 and the support frame 2 respectively, so as to prevent the mobile communication device 3 from falling off the support frame 2 after being touched.

[0029] Please see Figure 6 , Figure 7 and Figure 8 As shown, the charging process of this utility model can be selected as either wireless charging or wired charging, depending on the needs. Figure 6 and Figure 7 In this wireless charging process, a transmitting coil 41 is installed in the mobile charging device 1, and a receiving coil 42 is installed in the mobile communication device 3. When the mobile charging device 1 is activated, the energy storage battery 12 provides electrical energy by driving current flow through its terminal voltage. The current flows through the transmitting coil 41, and according to Ampere's law, a magnetic field is generated around the transmitting coil 41. This magnetic field changes with the current, i.e., it is an alternating magnetic field. When the mobile communication device 3 is placed near the mobile charging device 1, the receiving coil 42 senses the alternating magnetic field from the transmitting coil 41. Thus, the receiving coil 42 converts the alternating magnetic field into alternating current (AC) according to Faraday's law of electromagnetic induction. Since the receiving coil 42 still generates AC, the rectifier circuit inside the mobile communication device 3 converts this AC to direct current (DC). This is because the internal battery of the mobile communication device 3 typically requires DC for charging.

[0030] exist Figure 8In this wired charging process, a first connection port 43 is provided on the mobile charging device 1, and a second connection port 44 is provided on the mobile communication device 3. A connecting line 45 is provided between the first connection port 43 and the second connection port 44. When the mobile charging device 1 and the mobile communication device 3 are connected through the connecting line 45, the mobile charging device 1 activates the energy storage battery 12. The energy storage battery 12 provides power by driving current flow through its terminal voltage. The current flows from the first connection port 43 of the mobile charging device 1 through the connecting line 45 to the second connection port 44 of the mobile communication device 3. The connecting line 45 is responsible for transmitting current from the mobile charging device 1 to the mobile communication device 3. When current enters the second connection port 44 of the mobile communication device 3, the battery management system (BMS) of the mobile communication device 3 guides the current to its internal battery, which stores the current from the mobile charging device 1. When the internal battery of the mobile communication device 3 is fully charged, the battery management system of the mobile communication device 3 automatically stops the wired charging process.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, any equivalent changes in shape, structure or combination made without departing from the spirit and scope of the present utility model should be covered within the protection scope of the present utility model.
