[0039] It should be understood that the present application can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to make the disclosure thorough and complete and to fully convey the scope of the present application to those skilled in the art. In the drawings, the dimensions and relative sizes of layers and regions may be exaggerated for clarity. Like reference numerals throughout represent like elements.

When used herein, the term "and / or" includes any and all combinations of the relevant listed items.

[0041] In order to fully understand the present application, a detailed structure will be provided in the following description to illustrate the technical solution proposed in the present application. The preferred embodiments of the present application are described in detail below. However, in addition to these detailed descriptions, the present application may also have other implementation methods.

[0042] The following describes a charging device 100 according to an embodiment of the present application with reference to Figures 1 to 10. As shown in Figures 1 to 10, the charging device 100 includes: a wireless charging assembly 110, a power supply assembly 120, and a hinge assembly 130. The wireless charging assembly 110 is used to wirelessly charge an electronic device placed thereon; the power supply assembly 120 is electrically connected to the wireless charging assembly 110 and is used to supply power to the wireless charging assembly 110; the hinge assembly 130 includes a hinge bracket, a hinge 132, and a hinge 133. The hinge bracket is fixedly connected to the power supply assembly 120, the hinge bracket having a hinge slot, the hinge 132 being rotatably disposed in the hinge slot, and the hinge 133 being fixedly disposed on the hinge 132 and fixedly connected to the wireless charging assembly 110. The power supply assembly 120 and the wireless charging assembly 110 are foldably connected via the hinge assembly 130.

[0043] In one example, power supply assembly 120 is connected to wireless charging assembly 110, allowing power supply assembly 120 to supply its internal power to wireless charging assembly 110. Wireless charging assembly 110 can then use the received power to charge an electronic device placed on it via wireless charging. The electronic device may be a mobile phone, tablet, smartwatch, etc., without limitation.

[0044] In one example, the rotating shaft 132 rotates within the rotating shaft slot, allowing the charging device 100 to have at least two states: a folded state and an open state. When the rotating shaft 132 drives the wireless charging assembly 110 to rotate to abut against the power supply assembly 120 via the hinge 133, the charging device 100 is in the folded state, and the electronic device can be placed flat on the wireless charging assembly 110 for wireless charging by the wireless charging assembly 110. When the rotating shaft 132 drives the wireless charging assembly 110 to rotate to a certain angle between the wireless charging assembly 110 and the power supply assembly 120 via the hinge 133, the charging device 100 is in the open state, and the charging device 100 can function as an electronic device stand, and the electronic device can be placed at an angle on the wireless charging assembly 110 for wireless charging by the wireless charging assembly 110.

[0045] Based on this, the present application provides a charging device 100 with a folded state and an open state. According to the charging device 100 of the present application, the power supply component 120 and the wireless charging component 110 are foldably combined together via the hinge component 130, so that the charging device 100 can charge electronic devices through wireless charging and can also support electronic devices horizontally and tilted in the folded state and the open state, respectively. Thus, the charging device 100 can function as an electronic device stand, expanding the use scenarios of the charging device 100.

[0046] In one example, as shown in FIG3 , the charging device 100 further includes a wire 140 , through which the power supply assembly 120 is electrically connected to the wireless charging assembly 110 , and the hinge assembly 130 includes a wire hole 134 , through which the wire 140 is passed, and the wireless charging assembly 110 and the power supply assembly 120 respectively block the two ports of the wire hole 134 .

[0047] In one example, whether the charging device 100 is in a folded state or an open state, the wire 140 connecting the wireless charging component 110 and the power supply component 120 is passed through the wire hole 134 of the hinge component 130, and the wireless charging component 110 blocks one end of the wire hole 134, and the power supply component 120 blocks the other end of the wire hole 134. As a result, the wire 140 can be hidden by the wire hole 134, and the two ends of the wire hole 134 can be hidden by the wireless charging component 110 and the power supply component 120 respectively. Therefore, when the charging device 100 is in a folded state or an open state, there is no problem of exposing the internal wiring. For example, Figure 2 shows a back view of the charging device 100 in an open state, with the wire 140 in a hidden state, and Figure 3 shows a schematic diagram of the wire 140 passing through the wire hole 134 when the charging device 100 is in an open state.

[0048] The charging device 100 of this embodiment has a wire 140 connecting the wireless charging component 110 and the power supply component 120 that is passed through the wire hole 134 of the hinge component 130, and the two ends of the wire hole 134 are respectively blocked by the wireless charging component 110 and the power supply component 120. As a result, the wire 140 can be hidden regardless of whether the charging device 100 is in the folded state or the unfolded state, and the problem of exposing the internal wiring does not exist.

[0049] In one embodiment of the present application, as shown in FIG3 , the power supply assembly 120 includes: a first shell 121 ; a battery cell 122 disposed in the first shell 121 ; and a control module 123 connected to the battery cell 122 for managing the charge and discharge of the battery cell 122 .

[0050] In one example, one end of the wire 140 is connected to the control module 123, and the other end is connected to the wireless charging component 110. The electric energy of the battery cell 122 flows through the control module 123 and the wire 140 in sequence and is supplied to the wireless charging component 110, so that the wireless charging component 110 uses the received electric energy to charge the electronic device placed thereon through wireless charging.

[0051] In one example, as shown in Figure 3, the control module 123 is arranged in the first shell 121 near the hinge assembly 130 to shorten the distance between the control module 123 and the wireless charging assembly 110 and reduce the length of the wire 140; the battery cell 122 is arranged in the first shell 121 away from the hinge assembly 130.

[0052] In one example, the wire 140 connecting the wireless charging component 110 and the power supply component 120 can be a flat cable, also known as a flexible printed circuit (FPC). Of course, this application does not exclude the use of other types of wires.

[0053] In an example, the control module 123 may be a PCB (Printed Circuit Board), a PCBA (Printed Circuit Board Assembly, that is, a blank PCB board with SMT components), etc., which is not limited to this.

[0054] In one example, the control module 123 can monitor and control the charging and discharging processes of the battery cell 122 to ensure the safety, stability, and lifespan of the battery cell 122. For example, in charge management, the control module 123 can adopt an appropriate charging mode (such as trickle charging, constant current charging, constant voltage charging, etc.) based on the characteristics of the battery cell 122 to control the charging voltage and charging current, thereby improving charging efficiency and full charge rate. For example, in discharge management, the control module 123 can control the discharge current and discharge termination voltage based on the characteristics of the battery cell 122 to improve discharge efficiency and battery life. Of course, the control module 123 can also implement battery cell 122 status monitoring and management (real-time measurement of battery cell 122 parameters such as voltage, temperature, and internal resistance, estimation of battery cell 122 state of charge, remaining capacity, and fully charged capacity, reflecting the battery cell 122 usage and health status) and battery cell charge and discharge protection (preventing abnormal conditions such as overcharging, over-discharging, overcurrent, short circuit, and overtemperature in the battery cell to avoid damage or danger to the battery cell), etc., without limitation.

[0055] In one embodiment of the present application, as shown in FIG4 , the power supply assembly 120 further includes a cell protection module 125 , which is electrically connected to the cell 122 and the control module 123 , respectively. The cell protection module 125 is used to protect the cell 122 during charging and discharging.

[0056] In one example, the battery cell protection module 125 can be a circuit module for protecting the battery cell 122. It can monitor and control the charging and discharging status of the battery cell 122, prevent abnormal conditions such as overcharging, over-discharging, overcurrent, short circuit, overtemperature, etc., and protect and extend the service life of the battery cell 122.

[0057] In one example, the cell protection module 125 can be a cell protection board, such as a PCB (Printed Circuit Board), a PCBA (Printed Circuit Board Assembly, that is, a blank PCB board with SMT mounting), etc., without limitation.

[0058] In one example, the number of battery cells 122 is at least two, and at least two battery cells 122 are connected in series, wherein the pole tab of one battery cell 122 is connected to the control module 123, and the pole tab of the other battery cell 122 is connected to the battery cell protection module 125, and the power supply component 120 also includes an electrical connection portion 126, and the control module 123 and the battery cell protection module 125 are electrically connected through the electrical connection portion 126, and the spacing between the control module 123 and the battery cell protection module 125 matches the spacing between the pole tabs of two adjacent battery cells 122.

[0059] Taking two battery cells 122 connected in series as an example, as shown in Figures 4 and 5, the pole ears 1221 and pole ears 1222 of one battery cell 122 are connected to the control module 123, and the pole ears 1223 and pole ears 1224 of the other battery cell 122 are connected to the battery cell protection module 125. The electrical connection part 126 is located between the control module 123 and the battery cell protection module 125. The control module 123 and the battery cell protection module 125 are electrically connected through the electrical connection part 126. The spacing between the control module 123 and the battery cell protection module 125 matches the spacing between the pole ears of two adjacent battery cells 122, thereby increasing the area utilization of the control module 123.

[0060] In one example, the electrical coupling portion 126 includes a first coupling portion and a second coupling portion, wherein the first coupling portion is disposed on and electrically connected to the control module 123, and the second coupling portion is disposed on and electrically connected to the cell protection module 125. After the first coupling portion and the second coupling portion are coupled, the control module 123 and the cell protection module 125 are electrically connected. The electrical coupling portion 126 may be a pin-and-female header structure (one of the first and second coupling portions is a pin header and the other is a female header), a socket-and-plug structure (one of the first and second coupling portions is a socket and the other is a plug), etc., without limitation.

[0061] In one example, as shown in Figures 3 and 4, the power supply assembly 120 also includes a charge and discharge interface 124, the first shell 121 is provided with a charge and discharge interface slot 1211, the charge and discharge interface 124 is provided in the charge and discharge interface slot 1211, and the charge and discharge interface 124 is electrically connected to the control module 123.

[0062] In one example, the charging and discharging interface 124 can be a USB interface (such as USB-A, USB-B, Mini USB, Micro USB, Type-C, etc.), a Lightning interface, etc., without limitation.

[0063] In one example, the battery cell 122 can be charged through the charge and discharge interface 124, or the battery cell 122 can also be discharged through the charge and discharge interface 124. For example, when the battery cell 122 is low on power, the power supply assembly 120 can be connected to an external power supply device through the charge and discharge interface 124, and the external power supply device charges the battery cell 122 through the charge and discharge interface 124, and the control module 123 can perform charging management; or, the electronic device can also be directly connected to the power supply assembly 120 through the charge and discharge interface 124, and the battery cell 122 charges the electronic device through the charge and discharge interface 124, thereby allowing the charging device 100 to charge the electronic device through wireless charging by the wireless charging assembly 110, and also through wired charging by the power supply assembly 120.

[0064] In one example, the power supply assembly 120 may further include control buttons, indicator lights, etc., which are not limited to this. The control buttons may control the start and stop of the charging device 100, and the indicator lights may indicate the charging status, the charge level of the battery cell 122, etc., which are not limited to this.

[0065] In one embodiment of the present application, as shown in FIG6 , the wireless charging assembly 110 includes: a second shell 111 ; and a wireless charging coil 112 disposed in the second shell 111 for transmitting electrical energy to an electronic device placed in the wireless charging assembly 110 via wireless charging.

[0066] In one example, the power supply assembly 120 can be electrically connected to the wireless charging coil 112 via a wire 140. The power supply assembly 120 provides power to the wireless charging coil 112 via the wire 140, and the wireless charging assembly 110 uses the received power to charge an electronic device placed on the wireless charging assembly 110 via wireless charging.

[0067] In one example, in addition to managing the charge and discharge of the battery cell 122, the control module 123 can also control the wireless charging process of the wireless charging coil 112. For example, the control module 123 can control the transmission power of the wireless charging coil 112, which is not limited to this.

[0068] In one example, the wireless charging method of the wireless charging coil 112 can be electromagnetic induction, magnetic field resonance, radio wave, or other types, which are not limited.

[0069] In one example, the wireless charging standard of the wireless charging coil 112 may be the Qi standard, the Power Matters Alliance (PMA) standard, the Alliance for Wireless Power (A4WP) standard, iNPOFi technology, Wi-Po technology, or other standards, which are not limited thereto.

[0070] In one example, as shown in FIG6 , the wireless charging assembly 110 further includes a magnetic member 113 disposed on the second housing 111 for magnetically adsorbing the electronic device. The magnetic member 113 may be a magnet, and the electronic device may be magnetically adsorbed onto the wireless charging assembly 110 .

[0071] In one example, as shown in FIG7 , the wireless charging assembly 110 further includes a heat sink 114 disposed on the side of the second housing 111 facing away from the electronic device, for dissipating heat from the wireless charging coil 112. Specifically, the electronic device is placed on the front of the second housing 111, and the heat sink 114 is disposed on the back of the second housing 111. The heat sink 114 may be a metal heat sink (e.g., aluminum, copper, or a copper-aluminum composite), a water-cooled heat sink, a graphene heat sink, or the like, without limitation.

[0072] In one example, the second housing 111 may include a detachably connected upper housing and a middle housing, and the heat sink 114 is fixedly disposed on the back of the middle housing.

[0073] In one example, the heat sink 114 can be secured to the back of the intermediate housing using a variety of methods, including bolting, threading, welding, and the like, without limitation. For example, as shown in FIG6 , threaded holes are provided in the intermediate housing and the heat sink 114 to secure them together using screws. Furthermore, after the upper housing and the intermediate housing are assembled, the screws can be concealed within the internal cavity formed by the combined upper and intermediate housings.

[0074] In one example, there is torsional damping between the rotating shaft 132 and the rotating shaft slot. During the rotation of the rotating shaft 132 in the rotating shaft slot, the opening angle of the charging device 100 can be arbitrarily adjusted under the action of the torsional damping of the rotating shaft 132 .

[0075] In one example, the shaft bracket can be fixedly connected to the power supply assembly 120 in a variety of ways, such as bolted connection, threaded connection, welding, etc., which are not limited to this. For example, as shown in Figure 3, the shaft bracket and the power supply assembly 120 are provided with matching threaded holes, and the two can be fixed together by screws.

[0076] Similarly, the hinge 133 can also be fixed on the rotating shaft 132 in a variety of ways. The fixing methods can refer to the above description and will not be repeated here.

[0077] In one example, the hinge 133 can be located between the second shell 111 and the heat sink 114, and the hinge 133 can be clamped by the second shell 111 and the heat sink 114, so as to increase the strength and reliability of the shaft 132 assembly 130. The hinge 133 can be fixedly connected to the second shell 111 and the heat sink 114 by a variety of fixing methods. The fixing methods can refer to the description above and will not be repeated here. For example, as shown in Figure 8 (the heat sink 114 is omitted in the figure), the hinge 133 can be fixed between the intermediate shell and the heat sink 114 by thread-screw fixing. After the upper shell and the intermediate shell are assembled, the screws can be hidden in the internal cavity formed by the combination of the upper shell and the intermediate shell.

[0078] In one example, as shown in Figure 9, the pivot bracket includes a first pivot bracket 1311 and a second pivot bracket 1312, the first pivot bracket 1311 and the second pivot bracket 1312 are detachably connected, the first pivot bracket 1311 has a first rotation groove portion, and the second pivot bracket 1312 has a second rotation groove portion. After the first pivot bracket 1311 and the second pivot bracket 1312 are assembled, the first rotation groove portion and the second rotation groove portion are combined to form a rotation groove.

[0079] For example, threaded holes are provided on the first and second rotating shaft brackets 1311, 1312. After the first and second rotating shaft brackets 1311, 1312 are assembled, screws can be inserted into the threaded holes to secure the two together. Of course, other methods can also be used to secure the assembled first and second rotating shaft brackets 1311, 1312, and this is not limited to this.

[0080] In one example, the first pivot bracket 1311 further has a first threading hole portion, and the second pivot bracket 1312 further has a second threading hole portion. After the first pivot bracket 1311 and the second pivot bracket 1312 are assembled, the first threading hole portion and the second threading hole portion are combined to form the threading hole 134.

[0081] In one example, one end of the first pivot bracket 1311 also has a first pivot support portion, and one end of the second pivot bracket 1312 also has a second pivot support portion. After the first pivot bracket 1311 and the second pivot bracket 1312 are assembled, the first pivot support portion and the second pivot support portion are combined to form a pivot support portion 135.

[0082] For example, as shown in Figure 8, the second shell 111 has a groove, and the hinge support part 135 can be set in the groove. One end of the hinge bracket is connected to the second shell 111 through the hinge support part 135. When the hinge 132 drives the wireless charging component 110 to rotate through the hinge 133, the wireless charging component 110 can rotate around the axis of the hinge support part 135.

[0083] Exemplarily, FIG10 shows a schematic structural diagram of the first rotating shaft bracket 1311 , where the first rotating shaft bracket 1311 includes a first rotating groove portion 13111 , a first threading hole portion 13112 and a first rotating shaft support portion 13113 .

[0084] To summarize, according to the charging device of the embodiment of the present application, the power supply component and the wireless charging component are foldably combined together through the hinge component, so that the charging device can not only charge the electronic device by wireless charging, but also provide horizontal and tilted support for the electronic device in the folded state and the opened state respectively, so that the charging device can serve as a stand for the electronic device, thereby increasing the usage scenarios of the charging device.
