Wireless charging device

The present invention relates to a wireless charging device, and more particularly to an external wireless charging device.

Currently, various wireless charging devices are included in the market, which are provided with a wireless charging receiver disposed inside the handheld device to facilitate the charging operation of the handheld device on the wireless charging transmitter.

However, the handheld device of the built-in wireless charging receiver can only perform charging by pairing with a wireless charging transmitter corresponding to the same specification wireless communication protocol based on the provisions of the wireless communication protocol, greatly limiting the application of wireless charging.

Therefore, how to provide a wireless charging device that can be applied to handheld devices of various specifications has become an urgent research topic.

In view of the above problems, the main object of the present invention is to provide a wireless charging device including a wireless power transmitter, a wireless power receiver, and a connector. The wireless power transmitter has a positioning slot and is electrically connected to a power source. The wireless power receiver has a shape corresponding to the positioning groove to be placed in the positioning groove. The connector is connected to the wireless power receiver and the handheld device, wherein the wireless power receiving The device is connected to the back of the handheld device by a connector connection.

As described above, the present invention provides an external wireless charging device that is disposed outside the handheld device to facilitate application of the wireless charging device to various handheld devices, rather than only for built-in wireless charging. The handheld device of the device thus greatly increases the utility of the creation.

1 is a perspective view of the wireless charging device of the present invention; FIG. 2 is an exploded view of the wireless charging device of the present invention; and FIG. 3 is a cross-sectional view of the wireless charging device of the present invention.

Please refer to FIG. 1 , FIG. 2 and FIG. 3 , which are a perspective view, an exploded view and an A-A cross-sectional view of the wireless charging device of the present invention. The wireless charging device 1 includes a wireless power transmitter 11, a wireless power receiver 12, and a connector 13. The wireless power transmitter 11 has a positioning slot 111 and is electrically connected to a power source; the wireless power receiver 12 has a shape corresponding to the positioning slot 111 for receiving in the positioning slot 111; and the connector 13 is connected to the wireless power receiver. 12 and the handheld device M, wherein the wireless power receiver 12 is connected to the back of the handheld device M through the connector 13, so that the user can position the wireless power receiver 12 together with the handheld device M in the positioning slot of the wireless power transmitter 11. Wireless charging is performed in 111.

Further, the connector 13 is used to transmit the power received by the wireless power receiver 12 to the handheld device M.

As described above, in order to connect the wireless receiver 12 and the handheld device M more stably, the wireless charging device 1 further includes a casing 14 having a corresponding hand-held The shape of the device M and the accommodating groove 141 of the corresponding wireless power receiver 12, the accommodating groove 141 corresponds to the shape of the positioning slot 111 of the wireless power transmitter 11, which can be designed in the form of a slot for the user to wirelessly When charging, the wireless power receiver 12 and the handheld device M can be locked in the positioning slot 111 of the wireless power transmitter 11 by using the positioning slot 111.

The wireless power transmitter 11 includes a base having an angle of inclination. The tilt angle is between 10 degrees and 80 degrees, and the angle can be changed according to the user's needs, so that the user can simultaneously use the function of the handheld device M during charging.

The wireless charging device 1 includes an indicator light 15 disposed on the base for indicating a state of charge. For example, the indicator light 15 can indicate the state in which the handheld device M is currently in a charged state or has completed charging in various colors.

The wireless power transmitter 11 includes a sensor (not shown) for detecting an object disposed on the positioning slot 111 and disconnecting the wireless power supply when the object is not the handheld device M to ensure that the charging device is in use. Security.

In addition, the connector 13 includes a flexible structure that can be bent according to various use conditions, that is, the user can use the handheld device M without removing the outer casing 14, for example, when the data transmission of the handheld device M is to be performed, The connector 13 needs to be removed from the charging hole of the handheld device M, and the transmission line for data transmission is inserted into the charging hole of the handheld device M without removing the entire connector 13, the wireless power receiver 12 or the outer casing 14. In addition, for the handheld device M of different specifications, the user only needs to replace the connector 13, and the wireless power receiver 12 and the handheld device M can be connected.

In summary, the present invention provides an external wireless charging device, which is disposed outside the handheld device to facilitate wireless charging. The electrical device is applied to a variety of handheld devices, and is not limited to handheld devices for built-in wireless charging devices, thereby greatly increasing the utility of the present invention.
