Description

Hanging flexible wireless charging device 【0001】

The present invention relates to a wireless charging device, and more particularly to a hanging type flexible wireless charging device.

【0002】

Various portable electronic devices, such as mobile phones and tablet computers, have been widely used in daily life. In order to provide the power required for the operation of the portable electronic device, the internal battery of the charger must be charged by the charger. Since the wireless charging device can be applied to various use environments and is not limited by the power cord, it is convenient for the user to perform charging applications, and thus the wireless charging device has been gradually developed to replace the use of the wired charger.

[0003]

Wireless charging, also known as inductive charging or non-contact charging, provides energy from a power supply device to a powered device by wireless means. At present, the wireless charging technology is generally divided into three camps, the Wireless Power Consortium (WPC), the Power Matters Alliance (PMA), and the Wireless Power Alliance A4WP (Alliance For Wireless Power), among which WPC, The A4WP alliance is the mainstream, and the wireless charging method uses magnetic induction (low frequency) and magnetic resonance (high frequency) technologies. The magnetic induction mode can only be used for short-distance transmission and the power-receiving device needs to be attached to the power supply device. Although the power conversion efficiency is high, it is difficult to realize simultaneous charging of multiple power-receiving devices. Magnetic resonance is to let the transmitting end and the receiving end reach a certain resonance frequency, so that both sides can form a magnetic resonance phenomenon, and the energy transmission is achieved in this way. Compared with the magnetic induction method, the magnetic resonance method can realize charging over a long distance.

[0004]

Fig. 1 is a diagram showing a conventional wireless charging device for wirelessly charging a power receiving device. As shown in FIG. 1, the wireless charging device 11 transmits energy to the power receiving device 12 by wireless means, wherein the coil component of the wireless charging device 11 usually uses a multi-core copper wire coil and the copper wire coil is placed on the hard ferrite. The oxide substrate is mounted in the casing, so that the existing wireless charging device cannot be freely deformed according to the use requirements and the charging environment, and usually can only be placed on the desktop for charging, which will limit the charging application and reduce the convenience. In addition, the existing wireless charging device is also inconvenient to store and carry. In particular, when charging a large-sized power receiving device, the wireless charging device also needs to be large in size, heavy in weight, and difficult to carry.

[0005]

In addition, due to the different technologies used in the existing wireless charging devices, the coupling frequency of the coil components and the circuit design of the transmitting end are also different, resulting in incompatibility of the respective specifications of the products and incapability of sharing the components. Due to the incompatibility factor, the wireless charging device cannot use the same coil component and circuit component, so that various portable electronic devices need to use various customized wireless charging devices, which reduces the advantages and versatility of the wireless charging device. And it is not possible to wirelessly charge a plurality of power receiving devices using different wireless charging technologies with a single wireless charging device.

[0006]

The purpose of the present invention is to provide a hanging type flexible wireless charging device which is flexible and light in structure, and can be wirelessly charged by magnetic induction and/or magnetic resonance coupling, and can be hung or can be retracted for storage and carrying. It increases the flexibility and convenience of wireless charging applications and saves space.

【0007】

Another object of the present invention is to provide a hanging type flexible wireless charging device capable of transmitting electromagnetic waves of more than one different frequency, which can simultaneously or time-divisionally receive one or more power receiving devices capable of receiving electromagnetic waves of the same frequency or different frequencies. Charging is performed, and wireless charging can be implemented adaptively or selectively using magnetic resonance coupling or magnetic induction.

[0008]

In order to achieve the above object, a preferred embodiment of the present invention provides a hanging type flexible wireless charging device including a flexible carrier, at least one set of transmitting film coil components, and a hanging device. The flexible carrier comprises a main cloth member and at least one sub-cloth member, wherein the sub-cloth member is coupled to the main cloth member to form at least one bag body, each bag body having an opening and an accommodating space. The transmitting film coil component is disposed in the main fabric and is configured to emit electromagnetic waves of at least one frequency to wirelessly charge at least one power receiving device disposed in the accommodating space of the bag body.
