[0048] Specifically, in the embodiment, the first charging seat 21 can be used for wireless charging of a mobile phone or earphone, and the second charging seat 31 can be used for wireless charging of a watch.

[0049] More specifically, in the embodiment, the first slope 222 and the second slope 323 are respectively provided with two first magnetic attraction pieces 225 and two second magnetic attraction pieces 326, and are respectively arranged on the two sides of the contact pin 223 and the contact 324.

[0050] It can be understood that when the first slope 222 is close to the second slope 323, the first magnetic attraction piece 225 is aligned with the second magnetic attraction piece 326, the contact pin 223 is in contact with the contact 324 and is electrically connected, so that the two charging modules of the wireless charging device 1 are in a connected state, and at this time, the two charging modules can communicate electric quantity with each other, achieving the effect of simultaneous charging. In addition, by arranging the contact surfaces between the two charging modules as the first slope 222 and the second slope 323, the two magnetic attraction pieces are inclined, so as to facilitate the two magnetic attraction pieces to further adhere to each other by the action of gravity, and enhance the stability of the magnetic attraction connection between the first charging module 2 and the second charging module 3.

[0051] It can be understood that the two charging modules of the wireless charging device 1 are in a separated state by separating the contact pin 223 and the contact point 324 through an external force, at this time the first charging module 2 and the second charging module 3 can be used independently, which enhances the form diversity and portability of the wireless charging device 1.

[0052] Further, the first shell 22 further comprises a contact pin protruding column 224, and the contact pin 223 is located on the contact pin protruding column 224; the second shell 32 further comprises a contact point recess 325 corresponding to the contact pin protruding column 224, and the contact point 324 is located in the contact point recess 325; when the first charging module 2 and the second charging module 3 are connected, the contact point recess 325 accommodates the contact pin protruding column 224.

[0053] It can be understood that the cooperation of the contact pin protruding column 224 and the contact point recess 325 facilitates quick alignment when connecting the first charging module 2 and the second charging module 3, and also avoids the influence of the shaking of the two charging modules after being connected on the connection tightness between the contact pin 223 and the contact point 324, greatly improving the stability of the electrical connection between the two charging modules.

[0054] Please refer to Figures 2-6 Further, the face of the first shell 22 corresponding to the first charging seat 21 is a first charging face 221, and the face of the second shell 32 corresponding to the second charging seat 31 is a second charging face 322; the wireless charging device 1 comprises two preset states: placing the first charging face 221 and the second charging face 322 parallelly and connecting the first charging module 2 and the second charging module 3, at this time the state of the wireless charging device 1 is a flat state; after turning over the first charging module 2 upwardly, the first inclined face 222 is pasted with the second inclined face 323, the first charging module 2 is magnetically attracted and connected with the second charging module 3, and the angle between the two is an acute angle, at this time the state of the wireless charging device 1 is a support state.

[0055] Specifically, the contact pin 223 is a symmetrical design with the same direction at both ends, and can also be normally used when reversely connected with the contact point 324.

[0056] It can be understood that when the wireless charging device 1 is in the flat state, the mobile phone or earphone device is placed on the first charging seat 21; when the wireless charging device 1 is in the support state, the mobile phone or earphone device is magnetically attracted to the first charging seat 21 which is inclined, thereby realizing the switching of the two charging device use forms, adapting to different use scenarios, and further improving the practicability of the wireless charging device 1.

[0057] Further, the second inclined face 323 comprises a limiting edge 3231 arranged near one side of the second charging face 322, and the first inclined face 222 comprises a limiting groove 2221 arranged on the side away from the first charging face 221; when the wireless charging device 1 is in the support state, the limiting edge 3231 is clamped in the limiting groove 2221.

[0058] It can be understood that the clamping relationship between the limiting groove 2221 and the limiting side 3231 facilitates hindering the downward sliding trend of the first charging module 2 due to gravity in the support state, supporting and fixing the use form of the support state, thereby improving the structural stability of the wireless charging device 1.

[0059] Specifically, in the present embodiment, the second inclined surface 323 is further provided with a limiting protrusion 3232 away from the second charging surface 322; when the wireless charging device 1 is in the flat state, the limiting protrusion 3232 is clamped in the limiting groove 2221.

[0060] It can be understood that the limiting protrusion 3232 in the support state is in abutting relationship with the first charging module 2, supporting and avoiding the sharp part of the first charging module 2 from directly contacting the placement platform of the charging device, thereby damaging the first shell 22.

[0061] Further, the side edge of the first shell 22 is provided with at least one first wiring port 226.

[0062] It can be understood that the first wiring port 226 can charge the first charging module 2, or externally connect a data line to power other devices, thereby ensuring the functional integrity and practicality of the first charging module 2 when used separately.

[0064] Specifically, the maximum groove depth of the placement groove 321 is the same as the thickness of the charging block 311.

[0065] It can be understood that when the charging block 311 is placed in the placement groove 321, the watch can be placed flat on the second charging surface 322 for charging; the rotating shaft part 312 and the rotating shaft arm 313 drive the charging block 311 to rotate away from the second charging surface 322, so that the charging block 311 can be placed at an angle, facilitating the watch to be placed on the side of the charging block 311 for charging, thereby providing two optional charging methods for the user, improving the use diversity and ease of use of the second charging module 3.

[0066] Understandably, when the charging block 311 is placed in the placement slot 321, the rotating shaft part 312 is located in the internal space of the second shell 32 through the through hole 3211; by providing additional accommodation space for the rotating shaft part 312, the bottom wall of the placement slot 321 can be directly in contact with the charging block 311, avoiding the charging block 311 from moving away from the second charging surface 322 under the action of gravity, causing poor contact during watch charging, and improving the practicability of the second charging module 3.

[0067] Further, the rotating shaft arm 313 includes an abutting part 3131 connected to the second shell 32 and a bending part 3132 connected to the rotating shaft part 312, and the included angle between the bending part 3132 and the abutting part 3131 is obtuse; when the charging block 311 is rotated to a certain angle, the abutting part 3131 abuts against the inner wall of the second shell 32.

[0068] Understandably, when the abutting part 3131 abuts against the inner wall of the second shell 32, the charging block 311 reaches the maximum rotation position, that is, the supplementary angle of the included angle between the bending part 3132 and the abutting part 3131 is the maximum angle that the charging block 311 can actually rotate; by setting the included angle between the bending part 3132 and the abutting part 3131 as obtuse, the maximum angle that the charging block 311 can actually rotate is acute, which is convenient for the user to place the watch on the side, and the watch is not easy to move away from the charging block 311 when placed laterally, avoiding poor contact or even accidental slipping during watch charging, and improving the practicability of the second charging module 3.

[0069] Further, the inner wall of the placement slot 321 forms a first slot segment 3212 and a second slot segment 3213 in turn away from the bottom wall of the placement slot 321, the charging block 311 is partially accommodated in the first slot segment 3212, and the other part is exposed in the second slot segment 3213, and the diameter of the second slot segment 3213 is greater than that of the first slot segment 3212.

[0070] Understandably, the setting of the second slot segment 3213 provides a space for the user's fingers to move, which is convenient for the user to rotate the charging block 311, and improves the ease of use of the second charging module 3.

[0071] Further, the side of the charging block 311 away from the rotating shaft part 312 is provided with a groove 3111.

[0072] Understandably, the groove 3111 provides additional space for the user to rotate the charging block 311, which is easy for the fingers to rotate, improving the ease of use of the second charging module 3.

[0073] Further, at least one second wiring port 327 is arranged on the side of the second shell 32 away from the second inclined surface 323.

[0074] Understandably, the second wiring port 327 can charge the second charging module 3, or the external data line can power other devices, ensuring the functional integrity and practicality of the second charging module 3 when used separately.

[0075] Understandably, the watch can be placed flat or on the side when wirelessly charging, and when the watch is placed flat, the watchband is unfolded and placed on both sides adjacent to the second slope 323 of the second housing 32. The second wiring port 327 is arranged at the side away from the second slope 323, which is conducive to charging the second charging seat 31 while externally charging other devices, and avoids mutual interference between the two charging methods, improving the practicality of the second charging module 3 and the user's experience.
