[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0028] like Figures 1 to 3 As shown, the embodiment of the utility model provides a schematic diagram of a storage state and a schematic diagram of a use state of a wireless charger with a rotating structure.

[0029] The wireless charger includes three cavities, namely the first cavity 1, the second cavity 2 and the third cavity 3. A charging module is built into each cavity. The first cavity 1 and the second cavity 2 have a first inclined surface 11 and a second inclined surface 21 respectively. The first inclined surface 11 and the second inclined surface 21 fit each other. Fitting includes complete fit and partial fit. Complete fit means that the first inclined surface 11 and the second inclined surface 21 fit together completely. Partial fit means that the first inclined surface 11 and the second inclined surface 21 fit together partially, and each part is exposed outside. Figures 1 to 3 In the state, the first inclined surface 11 and the second inclined surface 21 are completely in contact with each other. Figure 1 The wireless charger is in the storage state (excluding the third cavity 3). Figure 2 and Figure 3 The wireless charger is in use (ignoring the third cavity 3), or in a folded state. Figure 1 Status changes to Figure 2 state, or from Figure 2 Status changes to Figure 1 During the state, the first inclined surface 11 and the second inclined surface 21 rotate relatively to each other, so the first inclined surface 11 and the second inclined surface 21 are only partially fitted.

[0030] In order to realize the relative rotation between the first inclined surface 11 and the second inclined surface 21, as shown in FIG. Figure 4 As shown, the wireless charger further includes a fixed rotating shaft 4, which is arranged in a direction perpendicular to the first inclined surface 11 and the second inclined surface 21, and is used to achieve relative rotation between the first inclined surface 11 and the second inclined surface 21 and achieve axial fixation.

[0031] Specifically, the first inclined surface 11 and the second inclined surface 21 are correspondingly provided with a first axial hole 111 and a second axial hole 211; the fixed rotating shaft 4 includes a fixing cap 41 and a fixing rod 42, wherein the fixing rod 42 is arranged in the first axial hole 111 and the second axial hole 211, the first inclined surface 11 and the second inclined surface 21 can be rotated with the fixing rod 42 as the rotating axis, and an annular groove 43 is arranged at one end of the fixing rod 42 away from the fixing cap 41, and the retaining spring 6 cooperates with the annular groove 43 to achieve axial fixation; the retaining spring 6 is specifically a circular ring with an opening, and at least three fixing protrusions 621 are arranged at intervals on the inner ring of the circular ring, and the three fixing protrusions 621 cooperate with the annular groove 43 to be very tight, and of course, the number of fixing protrusions 621 can be more.

[0032] Optionally, the fixed shaft 4 can also be directly set on the second inclined surface 21. There is no need to set an axial hole on the second inclined surface 21. The fixed shaft 4 rotates through the first axial hole 111 of the first inclined surface 11. On the back side of the first inclined surface 11, that is, the surface of the first inclined surface 11 away from the second inclined surface 21, a nut or a retaining spring 6 is provided to cooperate with the fixing rod 42 to fix the first inclined surface 11 and the second inclined surface 21.

[0033] Therefore, the retaining spring 6 or the nut is a fixing device, which is used to cooperate with the fixed shaft 4 for axial fixing, that is, perpendicular to the direction of the first inclined surface and the second inclined surface, or the axial direction of the fixed shaft 4.

[0034] refer to Figures 4 to 6 , spring probes 5 are symmetrically arranged on the left and right sides of the first inclined surface 11, and conductive contacts 7 are symmetrically arranged on the left and right sides of the second inclined surface 21, and the positions of the spring probes 5 and the conductive contacts 7 correspond to each other, the spring probes 5 are electrically connected to the charging module in the first cavity 1, and the conductive contacts 7 are electrically connected to the charging module in the second cavity 2; when the first inclined surface 11 and the second inclined surface 21 are completely fitted, the charging module built into the first cavity 1 and the charging module in the second cavity 2 are electrically connected; since the charging module in the first cavity 1 and the charging module in the second cavity 2 need to be electrically connected, and the first cavity 1 and the second cavity 2 often need to rotate relative to each other, the connection cable is very easy to be broken due to rotation, and the spring probes 5 and the conductive contacts 7 are matched, which realizes the conduction and avoids the technical problem that the cable is easily broken due to rotation. Of course, the spring probes 5 are arranged on the second inclined surface 21, and the conductive contacts 7 are arranged on the first inclined surface 11, which also has the same technical effect.

[0035] Magnets 8 are symmetrically arranged on the left and right sides of the first inclined surface 11, and magnets 8 are also symmetrically arranged on the second inclined surface 21, and the positions of the magnets 8 on the first inclined surface 11 and the second inclined surface 21 are correspondingly arranged. When in the storage state or the use state, the magnets 8 on the first inclined surface 11 and the second inclined surface 21 attract each other, causing the first inclined surface 11 and the second inclined surface 21 to be relatively more fixed.

[0036] The wireless charger includes a third cavity 3 with a built-in charging module. A groove 12 for accommodating the third cavity 3 is provided on the first cavity 1. Circular hollow shafts 122 are respectively provided on two opposite groove walls 121 in the groove 12, and the two circular hollow shafts 122 are both connected to the interior of the first cavity 1; connecting holes 31 are respectively provided on both sides of the third cavity 3 corresponding to the circular hollow shafts 122, and the two circular hollow shafts 122 are respectively provided in the two connecting holes 31, and the third cavity 3 can rotate relative to the first cavity 1 through the two circular hollow shafts 122.

[0037] For the third cavity 3, due to the limitation of the position and shape of the groove 12, its rotation angle itself is limited, and the conductive connector between the first cavity 1 and the third cavity 3 can be safely arranged in the middle of the circular hollow shaft 122 without worrying about the conductive connector being damaged due to its rotation.

[0038] A convex circular cavity 13 is formed on the surface of the first cavity 1, and a magnet block is built into the convex circular cavity 13 for fixing the device to be charged on the convex circular cavity 13. Figure 3 In the usage state shown, the mobile phone is generally attached to the first cavity 1, the wireless headset is placed on the upper surface of the second cavity 2, and the watch is hung on the third cavity 3. The three are wirelessly charged at the same time, which is very convenient to use. When not in use, they are neatly stored and easy to store.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0040] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
