[0034] Some embodiments of the present application will be described in detail with reference to the drawings. The following examples and features in the examples can be combined with each other in the case of no conflict.

[0035] As shown in Figure 1 and Figure 2 The utility model discloses an example of a wireless charging device 10 with a retractable cord function. The wireless charging device 10 with a retractable cord function provided by the utility model example is used for wireless charging of electronic devices, for example. Specifically, the wireless charging device 10 with a retractable cord function includes a housing 100, a turntable 200, a charging module 300, and a connecting cord 400, for example. The turntable 200 is disposed inside the housing 100, for example. The charging module 300 is disposed inside the housing 100 and fixedly disposed on one side of the turntable 200, for example. The charging module 300 rotates with the turntable 200, for example, and is used to power a first external device, for example. The connecting cord 400 is disposed inside the housing 100 and wound on the turntable 200, for example. The connecting cord 400 is electrically connected to the charging module 300. When the connecting cord 400 moves away from the housing 100, the connecting cord 400 drives the turntable 300 and the charging module 200 to rotate together, that is, the connecting cord 400 has the function of a retractable cord. For example, the connecting cord 400 can be wound clockwise on the turntable 200, so that when the connecting cord 400 is pulled out, the turntable 200 is driven by the connecting cord 400 to rotate counterclockwise; or the connecting cord 400 can be wound counterclockwise on the turntable 200, so that when the connecting cord 400 is pulled out, the turntable 200 is driven by the connecting cord 400 to rotate clockwise, for example. As shown in Figure 3 An example of the connecting cord 400 being wound counterclockwise on the turntable 200 is provided in this embodiment, for example.

[0036] The wireless charging device with a retractable cord function provided by the embodiment can rotate the charging module together with the turntable, so that it is not necessary to provide a conductive spring and a ring-shaped conductive area, which reduces the size of the wireless charging device and improves the portability of the wireless charging device.

[0037] Further, referring againFigure 1 and Figure 2 The shell 100, for example, comprises an upper shell 101 and a lower shell 102, and a rotating shaft 120 is arranged in the shell 100, and the two ends of the rotating shaft 120 are connected to the upper shell 101 and the lower shell 102, respectively. At least one end of the rotating shaft 120 is fixedly connected to the shell 100, so that the rotating shaft 120 is fixed to the shell 100. The rotating disc 300 and the charging module 200 are sleeved on the rotating shaft 120 and can rotate relative to the rotating shaft 120. When the connecting line 400 moves away from the shell 100, the connecting line 400 drives the rotating disc 200 and the charging module 300 to rotate around the rotating shaft 120. In this way, displacement of the rotating disc 200 during rotation is avoided.

[0038] As described above, referring to Figure 2 The wireless charging device 10 with the retractable line function further comprises an elastic member 500, for example, in the form of a spiral and sleeved on the rotating shaft 120. One end of the elastic member 500 is fixedly connected to the rotating disc 200, and the other end is fixedly connected to the rotating shaft 120. When the connecting line 400 moves away from the shell 100 and drives the rotating disc 200 to rotate, the elastic member 500 is in a compressed state. For example, the elastic member 500 is a spring, preferably a coil spring. The elastic member 500 is used to reset the rotating disc 200, that is, when the user finishes charging and the connecting line 400 needs to be retracted, the elastic force of the elastic member 500 can be used to reset the rotating disc 200 so that the connecting line 400 can be retracted.

[0039] Referring again to Figure 1 and Figure 2 The wireless charging device 10 with the retractable line function further comprises a circuit board 700 and a connecting plate 800. Specifically, the connecting plate 800 is fixedly arranged on one side of the rotating disc 200 close to the charging module 300, and the charging module 300 is fixedly arranged on the side of the connecting plate 800 away from the rotating disc 200. The circuit board 700 is fixedly arranged between the rotating disc 200 and the connecting plate 700, and the charging module 300 and the connecting line 400 are electrically connected to the circuit board 700, respectively. The circuit board 700 is arranged to facilitate the connection of the internal circuit of the wireless charging device 10 with the retractable line function, and the connecting plate 800 is arranged to avoid interference of the circuit board 700 with the charging module 300.

[0040] In one specific embodiment, referring to Figure 3The installation portion 210 is provided with a positioning portion 230, and the connecting line 400 comprises a fixed portion 430 and a telescopic portion 440 connected to both ends of the fixed portion 430. For example, the fixed portion 430 is located at the middle of the connecting line 400, and the telescopic portion 440 is located at both ends of the connecting line 400. When the telescopic portion 440 drives the rotating disc 200 to rotate together with the charging module 300, the fixed portion 430 is relatively static with the rotating disc 200. That is, the telescopic portion 440 can be pulled out by the user to change the length of the connecting line 400, and the fixed portion 430 is fixedly arranged on the rotating disc 200.

[0041] Specifically, referring back to Figure 3 The fixed portion 430 is provided with a connecting portion 431, which is electrically connected to the circuit board 700. That is, the connecting line 400 is electrically connected to the circuit board 700 through the connecting portion 431. In this way, when the user pulls the connecting line 400, the telescopic portion 440 is pulled out by the user to drive the rotating disc 200 to rotate, but since the fixed portion 430 and the circuit board 700 are both fixedly connected to the rotating disc 200, that is, there is no relative movement between them, and there is also no relative movement between the connecting portion 431 on the fixed portion 430 and the circuit board 700, so that the circuit board 700 is not pulled to cause poor electrical connection during the extension and contraction of the connecting line 400, that is, the rotation of the rotating disc 200.

[0042] Referring back to Figure 1 and Figure 2 The wireless charging device 10 with the telescopic line function comprises a magnetic member 600, which is arranged inside the shell 100 and fixedly arranged on the connecting plate 800 away from the circuit board 700. The magnetic member 600 is arranged to facilitate positioning of the external device when the external device is placed on the wireless charging device 10 with the telescopic line function. Preferably, the magnetic member 600 is a ring-shaped magnet, and the magnetic member 600 is preferably arranged on the side of the charging module 300 close to the rotating shaft 120.

[0043] Referring back to Figure 1 and Figure 2The two ends of the connecting line 400 are oppositely provided with a first connecting port 410 and a second connecting port 420, wherein one of the first connecting port 410 and the second connecting port 420 is used for connecting an external power supply, and the other is used for connecting a second external device to supply power to the second external device. The upper shell 101 and the lower shell 102 are buckled to form a first fixing seat 111 and a second fixing seat 112 oppositely arranged on both sides of the shell 100. The connecting line 400, for example, includes a storage state, when the connecting line 400 is in the storage state, the first connecting port 410 is stored in the first fixing seat 111, and the second connecting port 420 is stored in the second fixing seat 112.

[0044] For example, when the user needs to charge, for example, the connecting line 400 can be pulled out to the required length, so that the first connecting port 410 can be connected to the external power supply, the user can place the first external device on the wireless charging device with the telescopic line function, so that the charging module 300 can supply power to the first external device, and the second connecting port 420 can be connected to the second external device to supply power to the second external device, so as to meet the user's demand for charging multiple devices at the same time. Of course, the second connecting port 420 can also be connected to the external power supply, and the first connecting port 410 can be connected to the second external device, and the present application does not limit this. The first external device and the second external device mentioned above are, for example, electronic devices, such as mobile phones, wireless earphones, electronic watches, etc.

[0045] In addition, referring to Figure 1 and Figure 2 , the wireless charging device 10 with the telescopic line function further comprises a limiting piece 900, which is located on the side of the rotating disc 200 away from the charging module 300, and one end of the limiting piece 900 is rotatably connected to the shell 100. Specifically, one end of the limiting piece 900 is rotatably connected to the lower shell 102, and the other end of the limiting piece 900 is movably arranged on the rotating disc 200 to limit the rotating disc 200.

[0046] Specifically, referring to Figure 1 and Figure 4 , the limiting piece 900 is provided with a limiting convex point 910, and the side of the rotating disc 200 away from the charging module 300 is provided with a limiting track 220. When the rotating disc 200 rotates in a first direction, the limiting convex point 910 moves in a second direction on the limiting track 220, wherein the first direction is opposite to the second direction. That is, the rotating direction of the limiting convex point 910 on the limiting track 220 is opposite to the rotating direction of the rotating disc 200. Wherein, the first direction is, for example, the clockwise direction, and the second direction is, for example, the counterclockwise direction, or the first direction is the counterclockwise direction, and the second direction is the clockwise direction.

[0047] The specific movement track of the limiting piece 900 on the limiting track 220 and the state of the connecting line 400 in the wireless charging device 10 with the telescopic line function provided by the embodiment of the utility model are described below. Figures 4-7 Figure 3 In the embodiment, for example, the connecting line 400 is wound counterclockwise on the rotating disc 200, specifically, the shell 100 has oppositely arranged top and bottom surfaces, the top surface is the surface on which the first external device is placed for wireless charging, and when viewed from the angle of the top surface, the connecting line 400 is wound counterclockwise on the rotating disc 200; it should be understood that at this time, when viewed from the angle of the bottom surface, the connecting line 400 is wound clockwise on the rotating disc 200.

[0048] Firstly, the connecting line 400, for example, includes a storage state, at this time, the first connecting port 410 is stored in the first fixed seat 111, and the second connecting port 420 is stored in the second fixed seat 112. The limiting convex point 910 is located at an arbitrary position on the limiting track 220, for example, the limiting convex point 910 is located at the position of the inner circle of the limiting track 220 as shown in the figure. Figure 5

[0049] Secondly, when the user needs to use the wireless charging device, the user needs to pull the connecting line 400 to move the connecting line 400 in the direction away from the shell 100, at this time, the connecting line 400 is in the out-line state, and when viewed from the angle of the top surface, the connecting line 400 is pulled out of the shell 100 and drives the rotating disc 200 to rotate clockwise, and the elastic member 500 is compressed.

[0050] Thirdly, when the user pulls the connecting line 400 to the required length and the user stops pulling, the rotating disc 200 will rebound under the resetting action of the elastic member 500, that is, the rotating disc 200 moves counterclockwise and drives the connecting line 400 to retract, at this time, the connecting line is in the rebound state. At this time, when viewed from the angle of the bottom surface (i.e. the angle of Figure 5 and Figure 6 ), the rotating disc 200 rotates clockwise relative to the shell 100, since the movement is relative, the limiting convex point 910 at this time is equivalent to moving counterclockwise on the limiting track 220, referring to Figure 4 and Figure 5 , the limiting track 220 has a locking groove 221, when the limiting convex point 910 rotates counterclockwise on the limiting track 220 to the locking groove 221, the limiting convex point 910 stops rotating.

[0051] As described above, the connecting line 400 includes a locking state, referring to Figure 6 ​​When the connecting line 400 is in the locking state, the limiting bump 910 is located in the locking groove 221, and the limiting bump 910 cooperates with the locking groove 221 to limit the rotation disc 200, and the rotation disc 200 stops moving. At this time, the connecting line 400 is fixed, and the user can use the wireless charging device 10 with the telescopic line function without worrying about unnecessary movement of the connecting line 400.

[0052] Further, when the user needs to store the connecting line 400 after charging, the user needs to pull the connecting line 400 outward, that is, the connecting line 400 moves away from the shell 100, at this time, the connecting line 400 is in the first winding state, and the rotation disc 200 moves counterclockwise with the connecting line 400, at this time, the limiting bump 910 moves clockwise on the limiting track 220, so that the limiting bump 910 moves away from the locking groove 221 and moves to the outer circle of the limiting track 220.

[0053] Finally, after the user stops pulling the connecting line 400, the rotation disc 200 is reset under the reset action of the elastic member 500, and continues to be observed from the angle of the front bottom surface, at this time, the rotation disc 200 moves clockwise and drives the connecting line 400 to retract into the shell 100, at this time, the connecting line 400 is in the second winding state. For example, the position of the limiting bump 910 is shown in FIG. 9, and the limiting bump 910 is located on the outer circle of the limiting track 220. The limiting bump 910 rotates counterclockwise on the outer circle of the limiting track 220 until the first connecting port 410 and the second connecting port 420 of the connecting line 400 are completely stored in the first fixed seat 111 and the second fixed seat 112. Figure 7

[0054] It should be noted that the connecting line 400 can also be wound clockwise on the rotation disc 200, at this time, the limiting track 910 and the locking groove 920 on the rotation disc need to be adjusted adaptively, and the present application does not make specific limitation.

[0055] Preferably, the first fixed seat 111 and the second fixed seat 112 are respectively provided with a magnetic attraction structure, and the first connecting port 410 and the second connecting port 420 are respectively provided with a magnetic attraction structure, so that the first connecting port 410 and the second connecting port 420 can be better stored in the first fixed seat 111 and the second fixed seat 112.

[0056] The wireless charging device with the telescopic line function provided by the embodiment can fix the charging module on the rotation disc, so that the charging module can rotate with the rotation disc, without the need to set the conductive elastic sheet and the annular conductive region, thereby reducing the size of the wireless charging device and improving the portability of the wireless charging device.

[0057] ​It can be understood that the foregoing various embodiments are only exemplary descriptions of the present application, and under the premise that the technical features do not conflict, the structures are not contradictory, and the invention purpose of the present application is not violated, the technical solutions of various embodiments can be arbitrarily combined and used.

[0058] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
