[0034] In one embodiment, a heat dissipation hole connected to the first accommodating cavity is provided on the inner wall of the storage groove 140. When the slave charging seat is stored in the storage groove 140, the heat dissipation hole is hidden between the slave charging seat 200 and the storage groove 140. When the slave charging seat 200 is opened, the heat dissipation hole can be used to dissipate heat, thereby avoiding heat accumulation on the main charging seat 100 during charging, thereby improving the charging efficiency and life of the charging device.

[0035] The wireless charging device of this embodiment realizes the independent use of the slave charging seat 200 through the detachable connection between the main charging seat 100 and the slave charging seat 200, thereby improving the flexibility and practicality of the charging device; especially when the slave charging seat 200 is detached from the main charging seat 100, even if the main charging seat 100 is wirelessly charging a larger device to be charged that fully covers the surface of the main charging seat 100, it will not affect the use of the slave charging seat 200. At the same time, the detachable design reduces the accumulation of heat during charging, improves the charging efficiency and the life of the charging device. In addition, the main charging seat 100 and the slave charging seat 200 are connected through the first data line 300, which not only ensures the stability of charging, but also the first data line 300 can be used as a lanyard, greatly increasing the convenience of carrying and use by users.

[0036] It should be noted that, in the description of this application, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0037] In this embodiment, a ratio of a diameter value of the first wireless charging coil 110 to a diameter value of the second wireless charging coil 210 is greater than or equal to 1.3; and a charging power of the first wireless charging coil 110 is greater than a charging power of the second wireless charging coil 210 .

[0038] In a specific embodiment, the first wireless charging coil 110 is mainly used to wirelessly charge higher power devices (such as mobile phones, tablets, etc.), while the second wireless charging coil 210 is used to wirelessly charge lower power devices (such as watches, headphones, etc.).

[0039] In one embodiment, the first data cable 300 is detachably connected to the main charging base 100; and / or the first data cable 300 is detachably connected to the slave charging base 200.

[0040] See also Figure 4 In one embodiment, the first data cable 300 is detachably connected to the main charging base 100 .

[0041] Specifically, the control module 120 includes a first PCB board 121 and a first USB female connector disposed on the first PCB board 121. The housing of the main charging seat 100 is provided with a first plug opening 190 for the first data cable 300 to pass through.

A first USB male connector 310 is disposed at one end of the first data cable 300, and the first USB male connector 310 on the first data cable 300 is detachably connected to the first USB female connector on the first PCB board 121 through the first plug opening 190. It should be noted that in order to ensure the connection stability between the first data cable 300 and the main charging seat 100 and to prevent the main charging seat 100 from falling off from the first data cable 300 when the first data cable 300 is used as a lanyard, the first USB male connector 310 and the first USB female connector are designed to have a sufficiently large friction force.

[0042] The above-mentioned embodiment is only one of the embodiments of connecting the first data cable 300 to the main charging seat 100, and does not limit the specific implementation of the present invention in this aspect. In fact, according to different application scenarios and design requirements, the first data cable 300 and the main charging seat 100 can also be fixedly connected. For example, in a specific embodiment, an opening is opened on the outer shell of the main charging seat 100, and the first data cable 300 passes through the opening to enter the main charging seat 100 and is fixedly connected to the control module 120 in the main charging seat 100. In order to increase the connection stability of the first data cable 300, glue or a soft rubber sleeve can be applied at the position where the first data cable 300 contacts the opening, so that the first data cable 300 is stably connected to the outer shell of the main charging seat 100.

[0043] In another embodiment, the first data cable 300 is detachably connected to the slave charging base 200 .

[0044] Specifically, a second PCB board and a second USB female connector arranged on the second PCB board are provided inside the slave charging seat 200, the second PCB board is electrically connected to the second wireless charging coil 210, a second plug opening for the first data cable 300 to pass through is provided on the outer shell of the master charging seat 100, and the second USB female connector on the second PCB board faces the second plug opening. A second USB male connector is provided on the end of the first data cable 300 away from the first USB male connector 310, and the second USB male connector on the first data cable 300 is detachably connected to the second USB female connector on the second PCB board through the second plug opening. It should be noted that in order to ensure the connection stability between the first data cable 300 and the slave charging seat 200, and to prevent the slave charging seat 200 from falling off from the first data cable 300 when the first data cable 300 is used as a lanyard, the friction between the second USB male connector and the second USB female connector is designed to be sufficiently large.

[0045] The above embodiment is only one embodiment of the connection between the first data cable 300 and the slave charging seat 200, and does not limit the specific implementation of the present invention in this regard. In fact, according to different application scenarios and design requirements, the first data cable 300 and the slave charging seat 200 can also be fixedly connected. It adopts the same connection method as the first data cable 300 and the main charging seat 100. Since this connection method has been described in detail in the above content, the specific connection method will not be repeated here.

[0046] See also Figure 2 In this embodiment, the main charging seat 100 is provided with an escape opening 152 connected to the receiving groove 140 , and the escape opening 152 is used for allowing a finger to be inserted into the receiving groove 140 to take out the slave charging seat 200 .

[0047] In one embodiment, a non-slip groove is provided on one side of the slave charging seat 200 close to the escape opening 152. When the slave charging seat 200 is received in the receiving groove 140, the non-slip groove corresponds to the escape opening 152, making it easy to pull the slave charging seat 200 out with fingers.

[0048] In another embodiment, a non-slip protrusion is provided on one side of the slave charging seat 200 close to the escape opening 152. When the slave charging seat 200 is received in the receiving groove 140, the non-slip protrusion corresponds to the escape opening 152, making it easy to pull the slave charging seat 200 out with fingers.

[0049] In order to prevent the secondary charging seat from sliding out of the storage slot 140 during carrying, an embodiment of the utility model discloses that a stabilizing structure is provided between the secondary charging seat 200 and the storage slot 140 for fixing the secondary charging seat 200 in the storage slot 140 .

[0050] The stabilizing structure may be a wave dot structure, a slot structure, a magnetic structure, a buckle structure, a knob structure, a Velcro structure, a mortise and tenon structure, or a falcon joint structure.

[0051] In one embodiment, the stabilizing structure is a snap-fit ​​structure, which includes two elastic protrusions, which are respectively arranged on the two side walls of the slave charging seat, and the two inner walls of the storage groove 140 are respectively provided with grooves matching the elastic protrusions. When the slave charging seat 200 is pushed into the storage groove 140, the elastic protrusion is squeezed by the inner wall of the storage groove 140, so that it is in a compressed state. When the elastic protrusion slides to the position of the groove, due to the elastic potential energy stored by the previous compression, the elastic protrusion will quickly pop up and snap into the groove, thereby fixing the slave charging seat 200 and the main charging seat 100. When the slave charging seat 200 needs to be taken out, the slave charging seat 200 is pulled or pushed in the opposite direction. In this process, the elastic protrusion will be squeezed by the inner wall of the storage groove 140 again, and re-enter the compressed state, so that the elastic protrusion is no longer stuck in the groove, and the slave charging seat 200 can be smoothly taken out from the storage groove 140.

[0052] This embodiment provides a snap-fit ​​structure, which not only ensures a stable connection between the charging base 200 and the storage slot 140, but also provides a convenient removal method, thereby improving the user experience and convenience.

[0053] In another embodiment, the stable structure includes a magnetic attraction structure, and the magnetic attraction structure includes a first magnetic attraction member and a second magnetic attraction member, wherein the first magnetic attraction member is disposed in the storage slot 140, and the second magnetic attraction member is disposed on the slave charging base 200. When the slave charging base 200 is pushed into the storage slot 140, due to the magnetic attraction of the first magnetic attraction member and the second magnetic attraction member, the slave charging base 200 will be quickly and stably adsorbed in the storage slot 140. When the slave charging base 200 needs to be taken out, the user only needs to gently pull or push the slave charging base 200 to easily take the slave charging base 200 out of the storage slot 140.

[0054] This embodiment provides a magnetic attraction structure, which not only improves the connection stability between the charging base 200 and the storage slot 140, but also makes the removal process more convenient, providing users with a better use experience.

[0055] See also Figure 5 In this embodiment, the detachable multifunctional wireless charging device further includes a bracket 500, and the bracket 500 is rotatably connected to the main charging seat 100, and the bracket 500 can rotate within a preset angle range relative to the main charging seat 100.

[0056] The preset angle range may be 0 to 90 degrees. When the main charging base 100 does not need support, there is no angle between the bracket 500 and the main charging base 100. When the angle of the main charging base 100 relative to the desktop needs to be adjusted, the bracket 500 only needs to be rotated so that the bracket 500 rotates relative to the main charging base 100 until the angle between the bracket 500 and the main charging base 100 is greater than 0 degrees and less than or equal to 90 degrees.

[0057] In this embodiment, the main charging seat 100 includes a front side provided with the storage groove 140, a back side arranged opposite to the front side, a top side close to the first wireless charging coil 110, a bottom side close to the storage groove 140, and two side sides located between the top side and the bottom side, the side side is provided with a side groove at one end close to the bottom side, the bottom side is provided with a bottom groove, the bottom groove and the two side grooves are connected to form a U-shaped limiting groove 161 with an opening toward the top side, and the U-shaped limiting groove 161 is recessed from the back side of the main charging seat 100 toward the front side of the main charging seat 100; the bracket 500 is U-shaped, and the two ends of the bracket 500 are rotatably connected to the two side sides of the main charging seat 100 respectively, and the bracket 500 can be rotated into the U-shaped limiting groove 161.

[0058] Specifically, the U-shaped limiting groove 161 forms a step with the side of the main charging seat 100. When the bracket 500 is arranged in the U-shaped limiting groove 161, the step limits the bracket 500 toward the front of the main charging seat 100, so that the bracket 500 can only rotate toward the back of the main charging seat 100. When the bracket 500 is rotated to a certain angle (for example, 90 degrees), a side wall of the bracket 500 abuts against the end face of the side groove, so that the bracket 500 cannot continue to rotate toward the back of the main charging seat 100, thereby limiting the bracket 500 and limiting the rotation angle of the bracket 500 within a predetermined range.

[0061] In this embodiment, the second data cable receiving groove 151 is located on the front of the main charging base 100 and avoids the area of ​​the first wireless charging coil 110 and the storage groove 140. For example, the second data cable receiving groove 151 is located on the front of the main charging base 100 near the corner of one end of the first wireless charging coil 110, and does not affect the use of the second data cable 400 when the bracket 500 is used. Alternatively, the second data cable receiving groove 151 is located on the front of the main charging base 100 and is arranged near the storage groove 140, and the second data cable receiving groove 151 is connected to the avoidance port 152, so that the second data cable 400 can be easily taken out by fingers.

[0062] In another embodiment, the second data cable accommodating groove 151 is located on the side of the main charging seat 100 and is arranged away from the U-shaped limiting groove 161 , thereby effectively preventing the bracket 500 from affecting the use of the second data cable 400 .

The rechargeable battery 130 and the first PCB board 121 are both disposed at the bottom of the support plate 170, and the first PCB board 121 is located on the rechargeable battery 130. A circular mounting groove 171 is disposed on the top of the support plate 170, and the first wireless charging coil 110 is disposed in the circular mounting groove 171.

[0067] In this embodiment, the main charging stand 100 includes a rear shell 160 and a front shell 150, and the rear shell 160 and the front shell 150 are arranged to form the first accommodating cavity. The support plate 170 is provided with a flange 172 at one end away from the circular mounting groove 171, and the flange 172 is arranged to form the storage groove 140. A notch is provided at a position corresponding to the storage groove 140 on the front shell 150, so that the front shell 150, the rear shell 160 and the flange 172 are arranged to form the first accommodating cavity.

[0068] The wireless charging device of this embodiment has a compact structure, a small size and is easy to carry due to the spatial arrangement between various components.
