Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A portable charging device, as shown in figure 1, comprises a shell 1 with a containing space inside, wherein a PCBA board 2 and a wireless charging transmitting coil 21 electrically connected with the PCBA board are arranged in the shell; a magnet ring 31 formed by arranging a plurality of magnet blocks 31 is embedded in the shell, and a preset interval 4 is reserved between every two adjacent magnet blocks; the position of the magnet ring is located right above the wireless charging transmitting coil, and the diameter of the magnet ring is larger than that of the wireless charging transmitting coil.

Wherein, the inside accommodation space that is equipped with of casing can holding PCBA board and wireless transmitting coil that charges. The PCBA board and the wireless charging transmitting coil are essential components of the wireless charger, and are not described herein. The magnet ring is formed by arranging a plurality of magnetic magnet blocks (as shown in fig. 2), and a gap is reserved between every two adjacent magnet blocks, so that the whole magnet ring is in a non-closed circular ring shape; because this non-confined magnet ring is located wireless transmitting coil that charges directly over, and the diameter is greater than wireless transmitting coil that charges, can play two effects: namely, the position of the wireless charging transmitting coil is positioned in a magnetic circular ring area on the surface of the charging equipment; the interference of magnetism to the wireless charging process is avoided. The specific shape of the magnet block is not limited, and may be a fan shape cut with sharp corners, a rectangle, a polygon, or the like.

The housing is based on the PCBA board, the wireless charging transmitting coil, and the magnet ring included therein, and the external shape thereof is not particularly limited, and may be rectangular, circular, polygonal, and the like. Preferably, the casing material is stereoplasm or soft engineering plastic for this battery charging outfit's weight is lighter, more portable. Or, the shell can be made of composite materials (such as carbon fibers and Kevlar fibers), glass, synthetic rubber, wood or bamboo, natural or synthetic leather and the like, so that the shell can be suitable for various processes, such as spraying, printing, IMD, electroplating, heat/water transfer printing and the like, and has wide applicability.

In one application scenario, as shown in fig. 3, the portable charging device can charge a mobile phone with a magnet ring as well. Wherein, the smart phone 6 with wireless charging function is arranged in a mobile phone protective sleeve 9 with a magnet ring 8 at the end to be charged; shielding sheets 7 are also padded in the mobile phone and the protective sleeve to prevent the mobile phone from directly contacting with the magnet ring at the end to be charged; the size of the contact of the magnet ring at the end to be charged is the same as that of the magnet ring in the portable charging device, the position of the contact is right opposite, but the polarity of the contact is opposite. When the portable charging device is used for wirelessly charging the mobile phone, the two magnet rings attract each other to enable the charging device to be firmly fixed with the mobile phone protective sleeve, and the wireless charging receiving coil of the mobile phone is right opposite to the wireless charging transmitting coil of the charging device, so that the wireless charging efficiency can be greatly improved, and the charging time is shortened.

In the application scenario, the magnet blocks can be arranged and combined differently according to N, S polarities thereof, so as to increase the attraction force between the protective sleeve and the charger. For example, the magnet blocks are all N poles or S poles, and correspondingly, the magnet blocks of the terminal magnet ring to be charged are all S poles or N poles; alternatively, the magnet blocks are staggered at intervals of N, S poles, and correspondingly, the magnet blocks of the end magnet ring to be charged are staggered at intervals of S, N poles. When the magnet blocks are arranged alternately at intervals of N, S poles, the sliding of the magnet blocks during the adsorption of the magnet blocks can be further prevented.

It is understood that the portable charging device has a wireless charging function, and other electronic devices without a magnet ring and capable of being charged wirelessly are supported.

Further, in an embodiment, the PCBA board is circular and is adapted to the size of the wireless charging transmitting coil, that is, the PCBA board and the wireless charging transmitting coil are the same in size and are arranged in an overlapping mode, so that space can be saved, and the size of the shell can be made thinner conveniently.
