Description

General wireless charging device

Technical Field

The invention relates to the technical field of electronics, in particular to a universal wireless charging device.

Background

The charging modes of the mobile terminal in the current market comprise a wired charging mode and a wireless charging mode. The wireless charging method includes two types of Magnetic Induction (MI) and Magnetic Resonance (MR) in principle. The two wireless charging principles have the common advantage of solving the trouble of fussy plugging and unplugging a charging head when the mobile terminal is charged; but the common disadvantages are: the wireless charging energy loss ratio is large, and the efficiency is less than 70%.

Magnetic induction type wireless charging mode (the technical standard is called Qi protocol) also has ultra-short distance (about 5 mm) requirement, once the mobile terminal and the transmitting charging seat are deviated, the charging efficiency is greatly reduced by about 20 percent. Therefore, the Qi protocol wireless charger is neither energy-saving nor convenient to use, and has low market share.

The magnetic resonance wireless charging mode solves the problem of wireless energy transmission distance in principle, can reach more than 1 meter theoretically, but has large energy loss and does not completely solve the problem of electromagnetic interference to surrounding space. For example, a patient with a cardiac pacemaker may be life-threatening when entering a space with a magnetic resonance wireless charger. It has been reported that it is impossible to obtain a license in the united states until the problem is not completely solved. Thus, no product has been produced for the magnetic resonance charger so far.

These two types of wireless charging methods also have a common disadvantage: the receiving end of the mobile terminal must have a receiving coil and a circuit with larger volume, which can cause serious damage to the mobile terminal on the market, especially to the appearance of the mobile terminal.

Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-3, an embodiment of the present invention provides a universal wireless charging device, which includes a charging base 10 and a charging adapter 30;

the charging base 10 comprises a bottom plate 11, a horizontal baffle 20 and a vertical baffle 12 which are fixedly connected;

in the present embodiment, the bottom plate 11 is configured to enable the device to be charged 40 to be attached to the bottom plate 11 for charging.

The horizontal baffle 20 is also provided with a power supply contact plate 21 and a socket 22, the power supply contact plate 21 is electrically connected with the socket 22, and the socket 22 can be connected with an external power supply;

one end of the charging adapter 30 is provided with at least 2 conductive contacts, and the other end of the charging adapter 30 can be in plug connection with the device to be charged 40, that is, the charging adapter 30 can be inserted into a charging port of the device to be charged 40;

when the power supply contact plate 21 contacts with the conductive contact of the charging adapter 30, the external power source can charge the device to be charged 40.

In this embodiment, the external power source may be a dc power source.

In the present embodiment, the device to be charged 40 includes, but is not limited to, a mobile terminal product such as a mobile phone, a tablet computer, and the like.

In the present embodiment, the socket 22 is a dc socket, and the dc socket includes various USB sockets or Type-C sockets or sockets manufactured by apple inc. The charging adapter 30 is a dc plug, which includes various USB plugs or Type-C plugs or plugs of apple products. The receptacle 22 and the charging adapter 30 may or may not be standard conforming.

Referring to fig. 1, a horizontal baffle 20 is fixedly disposed at the lower portion of the bottom plate 11; the vertical baffle plates 12 are fixedly arranged on the left and/or right of the bottom plate 11, that is, one vertical baffle plate 12 can be fixedly arranged on the left or right of the bottom plate 11, or two vertical baffle plates 12 can be fixedly arranged on the left and right of the bottom plate 11. The vertical baffle 12 can provide a reference position for placing the device to be charged 40 and provide a basis for positioning the power supply contact plate 21.

Referring again to fig. 1, in order to better place the device to be charged 40, the charging base 10 may further include a first moving barrier 13 and a second moving barrier 14, and the first moving barrier 13 and the second moving barrier 14 are respectively connected to the bottom plate 11.

Further, a sliding groove (not shown in the figure) can be fixedly arranged on the bottom plate 11; the first moving barrier 13 and the second moving barrier 14 are connected to the first runner or the first guide rail, respectively. In this way, when the device to be charged 40 is being charged, the device to be charged 40 can be supported and balanced by the first moving shutter 13 and the second moving shutter 14. The first movable baffle 13 and the second movable baffle 14 can be adjusted to two sides or the same side of the charging port of the device to be charged 40 through the chute.

It should be noted that the first moving barrier 13 and the second moving barrier 14 can be connected to the bottom plate 11 through a chute-like structure, such as: guide rails, lead screws, etc.

It should be noted that more than 2 movable baffles may be provided for supporting and balancing the device to be charged 40.

In order to be able to adjust the position of the power supply contact plate 21 in a better way, a guide rail (not shown) can be fastened to the horizontal baffle 20, the power supply contact plate 21 being connected to the guide rail, since the position of the charging opening differs for different devices 40 to be charged.

Referring again to fig. 2 and 3, the charging adapter 30 includes a first conductive contact 31 and a second conductive contact 32; the power feeding contact plate 21 includes a first conductive electrode 211 and a second conductive electrode 212;

when the first conductive electrode 211 is in contact with the first conductive contact 31 and the second conductive electrode 212 is in contact with the second conductive contact 32, the external power source may charge the device to be charged 40.

In the present embodiment, when the first conductive electrode 211 contacts the first conductive contact 31 and the second conductive electrode 212 contacts the second conductive contact 32, a center line (shown by a dotted line in fig. 3) of the first conductive electrode 211 coincides with a center line of the first conductive contact 31 and a center line of the second conductive electrode 212 coincides with a center line of the second conductive contact 32.

In the present embodiment, the first conductive electrode 211 and the second conductive electrode 212 are elastic electrodes. The first conductive contact 31 and the second conductive contact 32 are insulated from each other; and the first and second

conductive contacts

31 and 32 are higher than the horizontal plane. The horizontal plane here refers to the plane in which the first conductive contact 31 and the second conductive contact 32 are mounted.

Please refer to fig. 3 again, in order to prevent the short circuit phenomenon. A spacing a between the first conductive contact 31 and the second conductive contact 32 is greater than a width d of the first conductive electrode 211 and/or the second conductive electrode 212; the spacing b between the first conductive electrode 211 and the second conductive electrode 212 is greater than the width c of the first conductive contact 31 and/or the second conductive contact 32.

When the universal wireless charging device is used, the charging adapter 30 is firstly inserted into a charging port of a device 40 to be charged, the first movable baffle 13 and the second movable baffle 14 on the charging base 10 can be adjusted to two sides (or the same side) of the charging port in advance according to the position of the charging port, and then the device to be charged is placed on the charging base 10 downwards by the left baffle and/or the right baffle (namely the vertical baffle 12).

In the process of putting the device to be charged into the charging device, the power supply contact plate 21 is horizontally moved to correspond to and be fixed to the position of the charging adapter of the device to be charged. Due to the self weight of the device to be charged, the external direct current power supply is fully contacted with the electrode contacts (the first conductive contact 31 and the second conductive contact 32) on the charging adapter through the elastic salient point electrodes (the first conductive electrode 211 and the second conductive electrode 212) on the power supply contact plate 21, so that wireless charging is realized.

It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
