DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] like Figure 1 As shown, an embodiment of the present application provides a charging device 100, which is used to charge an external device. The external device can be, for example, a mobile phone, a tablet computer, a wireless headset, a smart watch, etc.

[0025] The charging device 100 includes a base 110 and a rotating body 120 .

[0026] The base 110 is used to support the rotating body 120. The rotating body 120 is hinged to the base 110. The rotation axis of the rotating body 120 can be parallel to the horizontal direction, or parallel to the vertical direction, or between the horizontal direction and the vertical direction, which is not limited here.

[0027] The rotating body 120 can support external devices. When the rotating body 120 rotates, the angle of the charging device 100 changes, and the external device rotates synchronously with the rotating body 120, thereby adjusting the angle of the external device so that the user can choose a suitable angle to view the external device.

[0028] like Figure 2 As shown, in some embodiments, the base 110 includes a base body 111 and a first arm 112. The base body 111 can be shaped as a flat plate, thereby making the center of gravity of the base 110 relatively low and the base 110 more stable when placed on a desktop. The first arm 112 can be shaped as a rod, thereby saving materials.

[0029] The first arm 112 is protruded from the base 111 along a first direction A. The first direction A may be, for example, a direction perpendicular to the base 110 , or a direction inclined to the base 110 .

[0030] Optionally, the rotating body 120 is hinged to the first arm 112, and the rotating body 120 is spaced apart from the base 111, that is, the first arm 112 elevates the rotating body 120, and the rotating body 120 does not collide with the base 110 when rotating, thereby allowing the rotating body 120 to have a larger rotation range.

[0031] Optionally, one end of the first arm 112 away from the rotating body 120 is hinged to the rotating body 120 , thereby effectively utilizing the length of the first arm 112 and making the first arm 112 relatively short.

[0032] In some embodiments, the outer contour of the rotating body 120 can be a regular shape, so that the rotating body 120 is easy to design and manufacture, has good space utilization, and is more aesthetically pleasing. Optionally, the outer contour of the rotating body 120 can be cylindrical, truncated cone, rectangular parallelepiped, cube, spherical, etc.

[0033] like Figure 3 As shown, in some embodiments, a first rotating portion 1121 extending along the second direction B is provided on the first arm 112, the first rotating portion 1121 is hinged to the rotating body 120, and the first direction A and the second direction B are set at an angle, that is, the first direction A and the second direction B are not parallel, and the angle between the first direction A and the second direction B is greater than 0 degrees and less than or equal to 90 degrees.

[0034] Optionally, the first rotating portion 1121 is disposed through the rotating body 120 , and the first rotating portion 1121 is rotatably connected to the rotating body 120 , so that the rotating body 120 has two usable ends.

[0035] The following description uses the cylindrical outer contour of the rotating body 120 as an example. The rotating body 120 has two opposing end faces and a side surface connecting the two end faces. The first rotating portion 1121 is disposed through the side surface of the first rotating portion 1121. It is understood that if the first rotating portion 1121 were disposed on one end face of the rotating body 120, it would be difficult to install other functional modules on that end face due to the presence of the rotating body 120. However, in this embodiment, the first rotating portion 1121 is disposed through the side surface of the rotating body 120. Therefore, functional modules can be installed on both end faces of the rotating body 120, and both functional modules can follow the rotating body 120 to adjust the angle.

[0036] like Figure 3 As shown, in some embodiments, the charging device 100 further includes a hovering assembly 160, which is capable of generating damping. That is, the hovering assembly 160 is used to provide a rotational torque to the rotating body 120 relative to the first rotating portion 1121, thereby enabling the rotating body 120 to support the external device to hover at a preset angle. For example, a first threshold is determined based on the weight of a common external device. The first threshold is the torque of the common external device on the rotating device. The torque of the hovering assembly 160 is set to be greater than or equal to the first threshold so that the gravity of the external device itself cannot overcome the torque of the hovering assembly 160, and the external device can hover at a preset angle. Of course, the first threshold should not be too large, otherwise it will be more difficult for the user to rotate the rotating body 120.

[0037] In some embodiments, the rotation angle range of the rotating body 120 is a preset angle, and the preset angle can be set according to actual needs. For example, the rotating body 120 is cylindrical, and the preset angle is greater than 0 degrees and less than or equal to 360 degrees. Specifically, the preset angle can be 120 degrees, so that the tilt angle of the rotating body 120 can cover daily use situations and avoid the external device from colliding with the base 111 or the first bracket due to excessive rotation angle. Alternatively, the preset angle can also be 360 degrees, so that the rotating body 120 has a larger rotation range. Since the rotation amplitude of the rotating body 120 is relatively large, it is possible to rotate external devices such as mobile phones from facing forward to facing backward, or from facing left to facing right, so that a larger adjustment amplitude is provided when adjusting the angle.

[0038] In some embodiments, the charging device 100 further includes a driving member, the output end of which is fixedly connected to the rotating body 120. The driving member drives the rotating body 120 to rotate, thereby eliminating the need for the user to manually adjust the angle of the rotating body 120, thereby increasing user comfort when using the charging device 100. The driving member can be, for example, a motor. Due to the self-locking nature of the motor, the motor can also be used to achieve hovering of the rotating body 120.

[0039] like Figure 4 As shown, in some embodiments, the hovering assembly 160 is disposed between the rotating body 120 and the first rotating portion 1121 to prevent the rotating body 120 from rotating relative to the first rotating portion 1121. When no external force is applied, the rotating body 120 can remain hovering, thereby maintaining a fixed angle. When an external force is applied, the rotating body 120 can rotate, thereby adjusting the support angle of the rotating body 120 for the external device. In other embodiments, the hovering assembly 160 can be disposed between the rotating body 120 and the first support arm 112, or the hovering assembly 160 can be disposed between the rotating body 120 and the base 111.

[0040] like Figure 5 As shown, in some embodiments, the hovering assembly 160 includes a first connecting member 161 , a second connecting member 162 and an adjusting member 163 .

[0041] The first connecting member 161 and the second connecting member 162 are rotatably connected and damped. The adjusting member 163 abuts against the second connecting member 162 and rotates with the first connecting member 161, thereby providing a certain amount of torque (i.e., damping) when the first connecting member 161 rotates relative to the second connecting member 162. While providing torque, the hovering assembly 160 also serves as a rotating component between the first arm 112 and the rotating body 120, thereby reducing wear between the first arm 112 and the rotating assembly.

[0042] The adjustment member 163 is connected to both the first connecting member 161 and the second connecting member 162. The adjustment member 163 is used to adjust the force between the adjustment member 163 and the second connecting member 162, thereby changing the torque of the hovering assembly 160. The user can adjust the torque of the hovering assembly 160 according to their needs. When the torque of the hovering assembly 160 is relatively large, the rotating body 120 is relatively difficult to rotate, thereby being able to carry heavy external devices; when the torque of the hovering assembly 160 is relatively small, the user is relatively labor-saving when driving the rotating body 120 to rotate, and the rotating body 120 is suitable for carrying light external devices. The torque of the hovering assembly 160 in the embodiment of the present application can be adjusted to meet the usage habits of different users.

[0043] For example, Figure 5As shown, one end of the first connecting member 161 is fixedly connected to the rotating body 120, the other end of the first connecting member 161 is provided with an external thread, and the middle portion of the first connecting member 161 is provided with an abutment portion 1611. The adjusting member 163 is provided with an internal thread, and the adjusting member 163 is threadedly connected to the external thread on the first connecting member 161. For example, the adjusting member 163 can be a nut.

[0044] The second connecting member 162 includes a sleeve 1621 and a torsion washer (not shown in the figure) arranged in the sleeve 1621. The sleeve 1621 and the torsion washer are both sleeved on the first connecting member 161, and the sleeve 1621 and the torsion washer are both located between the abutting portion 1611 and the adjusting member 163. The sleeve 1621 is fixed to the first arm 112. The first connecting member 161 rotates relative to the sleeve 1621, and the torsion washer rotates with the first connecting member 161. Torque is generated between the torsion washer and the sleeve 1621. The adjusting member 163 can rotate relative to the first connecting member 161 to adjust the abutting pressure between the torsion washer and the sleeve 1621, thereby adjusting the torsion between the torsion washer and the sleeve 1621. The greater the acting force between the torsion washer and the shaft sleeve 1621 , the greater the torsion of the suspension assembly 160 ; and the smaller the acting force between the torsion washer and the shaft sleeve 1621 , the smaller the torsion of the suspension assembly 160 .

[0045] In some other embodiments, the suspension assembly 160 may only include a rubber ring, which is arranged between the first rotating portion 1121 and the rotating body 120. The rubber ring is used to increase the rotational resistance between the first arm 112 and the rotating body 120, thereby providing torque, so that the structure of the charging device 100 is relatively simple.

[0046] Of course, the charging device 100 may also not include the hovering component 160. The first rotating part 1121 is hinged to the rotating body 120 in an interference fit manner, and the friction between the first rotating part 1121 and the rotating body 120 provides torque, thereby further simplifying the structure of the charging device 100.

[0047] In some embodiments, a mounting slot 112b is provided on a side of the first arm 112 facing away from the first rotating portion 1121. The second connecting member 162 is fixedly mounted in the mounting slot 112b. The bottom wall of the mounting slot 112b restricts movement of the second connecting member 162 in the first direction A, while the sidewalls of the mounting slot 112b restrict rotation of the second connecting member 162 in the rotation direction of the rotating body 120. For example, the mounting slot 112b may be a hexagonal slot, and the second connecting member 162 may also be hexagonal in shape, thereby enabling the mounting slot 112b to restrict rotation of the second connecting member 162. Of course, the mounting slot 112b may be a non-circular slot, such as a triangular slot or a quadrangular slot, as long as the second connecting member 162 and the mounting slot 112b are compatible in shape.

[0048] In some embodiments, the hover assembly 160 includes a first buckle and a first bearing. The first buckle is fixedly connected to the first rotating portion 1121, and the first bearing is fixedly connected to the rotating body 120. The first bearing is sleeved on the first buckle and rotatably connected to the first buckle. The provision of the first buckle and the first bearing can reduce friction between the first rotating portion 1121 and the rotating body 120, thereby increasing the service life.

[0049] Optionally, damping oil may be provided between the first buckle and the first bearing, so that a rotational torque is generated between the first buckle and the first bearing to achieve a hovering effect. Alternatively, the first buckle and the first bearing may be interference fit to achieve a hovering effect.

[0050] like Figure 3 As shown, in some embodiments, the charging device 100 further includes a second arm 113. The second arm 113 can be shaped as a rod, thereby saving material. The second arm 113 protrudes from the base 111 along a third direction C. The third direction C can be the same as or different from the first direction A. The third direction C can be perpendicular to the base 110 or can be inclined to the base 110.

[0051] The second arm 113 is spaced apart from the first arm 112, and the rotating body 120 is hingedly connected to both the first arm 112 and the second arm 113. That is, the rotation axis between the rotating body 120 and the first arm 112 is collinear with the rotation axis between the rotating body 120 and the second arm 113. The provision of the second arm 113 allows both sides of the rotating body 120 to be supported, resulting in a more even force on both sides of the rotating body 120. This strengthens the connection between the rotating body 120 and the base 110, allowing the rotating body 120 to carry heavier external devices and providing greater stability during rotation.

[0052] like Figure 3 As shown, the second arm 113 extends along a fourth direction D to form a second rotating portion 1131. The second rotating portion 1131 is hingedly connected to the rotating body 120. The fourth direction D is opposite to the second direction B. That is, the second rotating portion 1131 is arranged opposite the first rotating portion 1121, and the rotating body 120 is located between the second rotating portion 1131 and the first rotating portion 1121. The second rotating portion 1131 and the first rotating portion 1121 can jointly limit the rotating body 120, thereby preventing the rotating body 120 from falling out from between the first arm 112 and the second arm 113.

[0053] Optionally, the second rotating portion 1131 is disposed through the rotating body 120 . The rotating body 120 is located between the first rotating portion 1121 and the second rotating portion 1131 , and is hinged to both the first rotating portion 1121 and the second rotating portion 1131 .

[0054] like Figure 6-Figure 7 As shown, in some embodiments, the rotating body 120 is provided with a coaxial first rotating hole 120a and a second rotating hole 120b, the first rotating portion 1121 is rotatably disposed in the first rotating hole 120a, and the second rotating portion 1131 is rotatably disposed in the second rotating hole 120b. In other embodiments, the positions of the rotating holes and the rotating portions can be reversed, that is, the first rotating hole 120a can be provided in the first support arm 112, the second rotating hole 120b can be provided in the second support arm 113, and the first rotating portion 1121 and the second rotating portion 1131 are both provided in the rotating body 120.

[0055] Generally speaking, compared with the first rotating hole 120a, the first rotating part 1121 is more susceptible to damage. Similarly, compared with the second rotating hole 120b, the second rotating part 1131 is more susceptible to damage. In this embodiment, the first rotating part 1121 is arranged on the first arm 112, and the second rotating part 1131 is arranged on the second arm 113. When the first rotating part 1121 or the second rotating part 1131 is damaged, since the light-emitting module 150 and the wireless charging module 140 are both arranged on the rotating body 120, replacing the first arm 112 or the second arm 113 is simpler than replacing the rotating body 120, and the replacement cost is lower.

[0056] like Figure 6 As shown, in some embodiments, the first connecting member 161 can pass through the first rotating hole 120a and extend into the interior of the rotating body 120 to be fixedly connected to the internal structure of the rotating body 120, thereby improving the connection strength between the second connecting member 162 and the rotating body 120. Optionally, the first rotating hole 120a can be a blind hole, and a limiting hole is defined on the bottom wall of the first rotating hole 120a. The end of the first connecting member 161 away from the adjusting member 163 passes through the limiting hole and extends into the interior of the rotating body 120. The limiting hole can be rectangular in shape, and the end of the second connecting member 162 away from the adjusting member 163 can be in the shape of a sheet that matches the limiting hole, so that the second connecting member 162 and the rotating body 120 can be limitedly matched in the rotation direction, and the second connecting member 162 can rotate synchronously with the rotating body 120.

[0057] like Figure 6 As shown, in some embodiments, one of the first rotating portion 1121 and the hole wall of the first rotating hole 120a is provided with a first limiting protrusion 121, and the other of the first rotating portion 1121 and the first rotating hole 120a is provided with a first limiting groove 112a. The first limiting protrusion 121 is slidably set in the first limiting groove 112a, and the first limiting protrusion 121 and the first limiting groove 112a are limitedly matched to limit the rotation angle of the rotating body 120 relative to the first arm 112.

[0058] Exemplarily, a first limiting groove 112a is provided on the first rotating part 1121, and a first limiting protrusion 121 is provided on the first rotating hole 120a. The first limiting groove 112a is in the shape of an arc. When the rotating body 120 rotates, the first limiting protrusion 121 rotates synchronously and slides in the first limiting groove 112a. When the first limiting protrusion 121 abuts against the end of the first limiting groove 112a, the first limiting protrusion 121 cannot continue to rotate, thereby achieving the limitation of the rotating body 120. It is understandable that when external devices such as mobile phones are relatively large in size and the mobile phone is fixed on the rotating body 120 and rotates with the rotating body 120, the mobile phone may collide with the base 110, the first arm 112 or the second arm 113. By setting the first limiting protrusion 121, the rotation angle of the rotating body 120 can be limited, thereby preventing larger external devices such as mobile phones from colliding with the base 110, the first arm 112 or the second arm 113, thereby improving safety.

[0059] like Figure 6 As shown, in some embodiments, in the rotation direction of the rotating body 120, the first limiting protrusion 121 abuts against the two side walls of the first limiting groove 112a to limit the rotation of the rotating body 120, and the difference between the dimensions of the first limiting protrusion 121 and the first limiting groove 112a in the rotation direction of the rotating body 120 defines the rotation range of the rotating body 120.

[0060] like Figure 7 As shown, in some embodiments, one of the second rotating portion 1131 and the hole wall of the second rotating hole 120b is provided with a second limiting protrusion 122, and the other of the second rotating portion 1131 and the second rotating hole 120b is provided with a second limiting groove 113a, and the second limiting protrusion 122 is slidably set in the second limiting groove 113a, and the second limiting protrusion 122 and the second limiting groove 113a are limitedly matched to limit the rotation angle of the rotating body 120 relative to the second support arm 113.

[0061] Exemplarily, a second limiting groove 113a is provided on the second rotating part 1131, and a second limiting protrusion 122 is provided on the second rotating hole 120b. The second limiting groove 113a is in the shape of an arc. When the rotating body 120 rotates, the second limiting protrusion 122 rotates synchronously and slides in the second limiting groove 113a. When the second limiting protrusion 122 abuts against the end of the second limiting groove 113a, the second limiting protrusion 122 cannot continue to rotate, thereby achieving the limitation of the rotating body 120. It is understandable that when external devices such as mobile phones are relatively large in size and the mobile phone is fixed on the rotating body 120 and rotates with the rotating body 120, the mobile phone may collide with the base 110, the first arm 112 or the second arm 113. By setting the second limiting protrusion 122, the rotation angle of the rotating body 120 can be limited, thereby avoiding collision of larger external devices such as mobile phones with the base 110, the first arm 112 or the second arm 113, thereby improving safety.

[0062] like Figure 6-Figure 7 As shown, in some embodiments, the first limiting protrusion 121, the first limiting groove 112a, the second limiting protrusion 122 and the second limiting groove 113a can be set at the same time, so that the first limiting protrusion 121 and the second limiting protrusion 122 can limit the rotating body 120 at the same time to improve the limiting effect, and enable both sides of the rotating body 120 to be subjected to force at the same time when limiting, and the force is more uniform.

[0063] like Figure 7 As shown, in some embodiments, in the rotation direction of the rotating body 120, the second limiting protrusion 122 abuts against the two side walls of the second limiting groove 113a to limit the rotation of the rotating body 120, and the difference between the dimensions of the second limiting protrusion 122 and the second limiting groove 113a in the rotation direction of the rotating body 120 defines the rotation range of the rotating body 120.

[0064] In some embodiments, the wall of the second rotation hole 120b is provided with a second limiting protrusion 122. The charging device 100 further includes a second buckle 170 and a second bearing 220. One end of the second buckle 170 is fixedly connected to the second rotation portion 1131. The other end of the second buckle 170 extends through the second rotation hole 120b and is provided with a flange 171. The second bearing 220 is fixedly connected to the rotating body 120. The bearing is sleeved on the second buckle 170 and is rotationally connected to the second buckle 170. The second buckle 170 is disposed between the flange 171 and the second limiting protrusion 122. The flange 171 and the second limiting protrusion 122 jointly limit the second buckle 170, thereby preventing the second buckle 170 from falling off the second bearing 220. The structures of the first buckle and the first bearing described above can refer to the second buckle 170 and the second bearing 220.

[0065] like Figure 8-Figure 9 As shown, in some embodiments, the second rotating portion 1131 is a hollow structure, the outer wall of the second buckle 170 is arranged to fit the inner wall of the second rotating portion 1131, one of the outer wall of the second buckle 170 and the inner wall of the second rotating portion 1131 is provided with a limiting hole 170a, and the other of the outer wall of the second buckle 170 and the inner wall of the second rotating portion 1131 is provided with a third limiting protrusion 123, the limiting hole 170a and the third limiting protrusion 123 are limitedly matched to limit the second buckle 170 from moving along the second direction B or the fourth direction D, and to limit the second buckle 170 from rotating relative to the second arm 113.

[0066] For example, the outer wall of the second pressing buckle 170 is provided with a limiting hole 170a, and the inner wall of the second rotating portion 1131 is provided with a third limiting protrusion 123. When assembling the second pressing buckle 170 with the second support arm 113, the second pressing buckle 170 is directly inserted into the second rotating portion 1131 until the third limiting protrusion 123 is locked in the limiting hole 170a, thereby completing the assembly, which is relatively convenient and quick. No other components are required to fix the second pressing buckle 170 to the second support arm 113, resulting in a relatively simple structure and low cost. Optionally, the second pressing buckle 170 and the second rotating portion 1131 can have an interference fit, thereby further enhancing the limiting effect of the second pressing buckle 170 and the second rotating portion 1131.

[0067] like Figure 10 As shown, in some embodiments, the charging device 100 further includes a counterweight 114 , which is disposed in the base 111 , thereby further lowering the center of gravity of the base 110 , making the charging device 100 more stable.

[0068] like Figure 1 As shown, in some embodiments, the charging device 100 further includes a wireless charging module 140 , which is disposed on the rotating body 120 , and is used to charge external devices.

[0069] like Figure 2 and Figure 4 As shown, the wireless charging module 140 includes a coil 141, a main control board 142, a magnetic isolation plate 143 and a magnet 144. The main control board 142 is electrically connected to the coil 141. The main control board 142 is used to control the coil 141 to transmit electromagnetic signals. The receiving coil 141 in the external device can receive the electromagnetic signal and convert it into current for charging.

[0070] The magnetic isolation sheet 143 is disposed between the main control board 142 and the coil 141 . The magnetic isolation sheet 143 can reflect electromagnetic signals, thereby allowing the electromagnetic signals to propagate toward external devices and preventing the electromagnetic signals from affecting the main control board 142 .

[0071] The magnet 144 is disposed around the coil 141 , and the magnet 144 can be attracted to an external device, so that the external device and the wireless charging module 140 are aligned and not easily deviated, thereby improving charging efficiency.

[0072] like Figure 4 As shown, in some embodiments, the charging device 100 further includes a light-emitting module 150, which is disposed on the rotating body 120, and a light-transmitting portion is provided at a position of the rotating body 120 corresponding to the light-emitting module 150. The light-emitting module 150 can illuminate the surrounding environment, thereby functioning as a desk lamp, a night light, or an atmosphere light. When a user uses a mobile phone in a dark scene, the light-emitting module 150 can reduce the brightness difference between the mobile phone screen and the surrounding environment, thereby protecting the user's eyes. When the rotating body 120 rotates, the light-emitting module 150 can rotate with the rotating body 120, that is, the light-emitting module 150 can adjust its angle, so that the light-emitting module 150 can illuminate different positions, which is more convenient to use.

[0073] like Figure 4 As shown, in some embodiments, the rotating body 120 has a first end 125 and a second end 126 that are separated from each other, the wireless charging module 140 is disposed at the first end 125, and the charging device 100 further includes a light-emitting module 150, which is disposed at the second end 126. The wireless charging module 140 and the light-emitting module 150 can be the two functional modules mentioned above. Optionally, the rotating body 120 is hinged to the first arm 112 at a position midway between the first end 125 and the second end 126, so that the first arm 112 can be relatively short, the forces on the first end 125 and the second end 126 of the rotating body 120 are relatively balanced, and the rotating body 120 is subjected to relatively less centrifugal force during rotation.

[0074] like Figure 4 As shown, in some embodiments, the light-emitting module 150 is disposed away from the wireless charging module 140, that is, the light emitted by the light-emitting module 150 is directed away from the wireless charging module 140. Generally speaking, when a mobile phone is placed on the wireless charging module 140 for charging, the screen of the mobile phone is facing the user. Since the light emitted by the light-emitting module 150 is directed away from the wireless charging module 140, the light-emitting module 150 does not directly shine toward the user, thereby preventing the light-emitting module 150 from irritating the user's eyes. The rotating body 120 can simultaneously drive the light-emitting module 150 and the light-emitting module 150 to rotate, thereby simplifying the structure of the charging device 100 and reducing costs.

[0075] like Figure 4As shown, in some embodiments, the light module 150 includes a light board 151, which is provided with a plurality of LED lamp beads. The LED lamp beads have high brightness, are relatively energy-efficient, and have a long service life. Optionally, the light board 151 is provided with a reflective coating that reflects light, thereby making the light from the light board 151 more concentrated and brighter.

[0076] like Figure 4 As shown, in some embodiments, one of the light board 151 and the main control board 142 is provided with a plug-in portion 1421, and the other of the light board 151 and the main control board 142 is provided with a mating portion 1511. The light board 151 and the main control board 142 are plugged and mated via the plug-in portion 1421 and the mating portion 1511, thereby making it easier to assemble the light board 151 and the main control board 142. For example, the plug-in portion 1421 is a pin header and the mating portion 1511 is a female header, or the plug-in portion 1421 is a male connector for a flat cable and the mating portion 1511 is a female connector for a flat cable. The main control board 142 is used to power the light board 151 and drive the multiple LED lamp beads to light up or change the color temperature.

[0077] like Figure 4 As shown, in some embodiments, the light-emitting module 150 is disposed within the rotating body 120. The rotating body 120 can have a light-gathering effect, thereby relatively converging the light emitted by the light-emitting module 150 and improving its directionality. Optionally, the rotating body 120 also includes a light-transmitting cover 124 disposed at the second end 126. The light-transmitting cover 124 has a light-transmitting portion. The light-emitting module 150 and the light-transmitting cover 124 are spaced apart. The light-transmitting cover 124 has a light-transmitting effect. The light emitted by the light-emitting module 150 can be transmitted through the light-transmitting cover 124 to the outside of the rotating body 120. Optionally, the light-transmitting cover 124 is translucent and can also serve to even out the light.

[0078] like Figure 4 As shown, in some embodiments, the light emitting module 150 further includes a light uniforming cover 152 , which is disposed on the light board 151 to further uniformly distribute the light.

[0079] like Figure 10As shown, in some embodiments, the charging device 100 further includes an operating module 190 disposed within the base 111. Since the base 111 is typically stationary, rotating the main body 120 to different angles does not affect the user's ability to operate the operating module 190. The operating module 190 is electrically connected to the light-emitting module 150 and can be used to adjust the color temperature, brightness, or both of the light-emitting module 150. The operating module 190 can be touch-sensitive and disposed within the base 111, thereby protecting the operating module 190 and extending its service life. The light-emitting module 150 can be operated by touching the surface of the base 111, thereby improving the sealing and aesthetics of the base 111. Alternatively, the operating module 190 may be a button type or a knob type, which is not limited here.

[0080] In some embodiments, the charging device 100 also includes a rechargeable battery, which is disposed in the rotating body 120 or the base 111, and the rechargeable battery is electrically connected to the wireless charging module 140 and the light-emitting module 150 to power the wireless charging module 140 and the light-emitting module 150. The charging device 100 can be illuminated or charged without an external power supply, making it convenient for the user to move the charging device 100 at any time.

[0081] like Figure 10 As shown, in some embodiments, the charging device 100 further includes a connection terminal 180 , which is disposed on the base 111 . The connection terminal 180 is electrically connected to the wireless charging module 140 and the light-emitting module 150 to supply power to the wireless charging module 140 and the light-emitting module 150 .

[0082] Connecting terminal 180 is used to connect a power cord, which supplies power to charging device 100 through connecting terminal 180. Connecting terminal 180 can be, for example, a type-A connector, which is relatively common. Connecting terminal 180 is located on base 111. When charging device 100 is in use, base 111 is typically stationary, and thus the power cord is also stationary, ensuring a more stable power supply.

[0083] like Figure 11 and Figure 12As shown, in some embodiments, a first installation cavity 111a is provided in the base body 111, a first wire-passing channel 113b communicating with the first installation cavity 111a is formed inside the first arm 112, a second installation cavity 120c is provided in the rotating body 120, and a second wire-passing channel 170b is formed inside the second rotating part 1131, and the second wire-passing channel 170b is communicated with the first wire-passing channel 113b and the second installation cavity 120c.

[0084] Since the first installation cavity 111a, the first wire passage 113b, the second wire passage 170b, and the second installation cavity 120c are connected in sequence, the electrical components in the base 110 and the electrical components in the rotating body 120 can be electrically connected through the wire 210, and the wire 210 will not be leaked outside the charging device 100, which is safer and more beautiful.

[0085] For example, the wire 210 can connect the operating module 190 and the light-emitting module 150. The wire 210 extends from the first installation cavity 111a through the first wire channel 113b and the second wire channel 170b in sequence to the second installation cavity 120c. The wire 210 can supply power to the operating module 190 and the wireless charging module 140, and the operating module 190 can control the light-emitting module 150 through the wire 210.

[0086] In some embodiments, the charging device 100 further includes a limiting component, which is provided on the rotating body 120 or the wireless charging module 140, and is used to limit the external device. The limiting component can be a clamping member, which can be provided on the rotating body 120, and the clamping member fixes the external device by clamping. Alternatively, the limiting component can be a magnet 144, which is magnetically fixed to the external device, and the magnet 144 can be integrated into the wireless charging module 140. When the rotating body 120 rotates, the limiting component and the external device fixed on the limiting component can rotate with the rotating body 120, so that the external device can adjust its angle, that is, the rotating body 120 acts as a bracket.

[0087] The wireless charging module 140 can be arranged corresponding to the limiting component. When the external device is positioned in conjunction with the limiting component, the external device is within the effective charging range of the wireless charging module 140, and the wireless charging module 140 can charge the external device. For example, the wireless charging module 140 is arranged near the limiting component. When the external device is fixed to the limiting component, the wireless charging module 140 is relatively close to the external device, thereby enabling the external device to be charged or the charging efficiency to be higher.

[0088] In some embodiments, the first arm 112 is hingedly connected to the base 111, and the rotation axis of the first arm 112 is arranged at an angle to the rotation axis of the rotating body 120. This allows the rotating body 120 to rotate freely in two directions, making the rotation more flexible. Specifically, the rotating body 120 rotates about a first axis E, which is parallel to the first direction A. The first arm 112 rotates about a second axis F, which is arranged at an angle to the second axis F. The angle between the first axis E and the second axis F is greater than 0 degrees and less than or equal to 90 degrees.

[0089] like Figure 13 As shown, in some embodiments, the seat body 111 includes an upper seat 1111 and a lower seat 1112. The upper seat 1111 and the lower seat 1112 are rotatably connected about a third axis G. The third axis G is arranged at an angle to the first axis E. The rotating body 120 has rotational freedom in two directions, which makes the rotation more flexible. The angle between the third axis G and the first axis E is greater than 0 degrees and less than or equal to 90 degrees.

[0090] like Figure 13 As shown, in some embodiments, the first arm 112 is hingedly connected to the base 111 about the second axis F, and the upper base 1111 and the lower base 1112 are rotatably connected about a third axis G. The third axis G is arranged at an angle to both the first axis E and the second axis F, thereby enabling the rotating member 130 to have three degrees of rotational freedom, providing greater rotational flexibility. For example, the rotating body 120 can swing forward and backward, the first arm 112 can swing left and right, and the base 110 can rotate horizontally, allowing the rotating body 120 to freely adjust its orientation in three dimensions. The angle between the third axis G and the second axis F is greater than 0 degrees and less than or equal to 90 degrees.

[0091] like Figure 14 and Figure 15 As shown, in some embodiments, the charging device 100 further includes a rotating member 130, which includes an inner ring 131 and an outer ring 132. The inner ring 131 and the outer ring 132 are rotatably connected. One of the lower seat 1112 and the upper seat 1111 is connected to the inner ring 131, and the other of the lower seat 1112 and the upper seat 1111 is connected to the outer ring 132. The lower seat 1112 and the upper seat 1111 are rotatably connected via the rotating member 130. The provision of the rotating member 130 can reduce wear between the inner ring 131 and the outer ring 132, thereby increasing the service life of the inner ring 131 and the outer ring 132, and can reduce friction, thereby making the inner ring 131 and the outer ring 132 rotate more smoothly.

[0092] Optionally, lubricating oil or a rolling element may be provided between the inner ring 131 and the outer ring 132 to make the inner ring 131 and the outer ring 132 rotate more smoothly. The rotating element 130 may be a ball bearing, for example.

[0093] like Figure 14 and Figure 15 As shown, in some embodiments, a first mounting portion 1113 is protruded from the surface of the upper seat 1111 facing the lower seat 1112, and a second mounting portion 1114 is protruded from the surface of the lower seat 1112 facing the upper seat 1111. The first mounting portion 1113 is connected to the outer surface of the outer ring 132, and the second mounting portion 1114 is connected to the inner surface of the inner ring 131. For example, the first mounting portion 1113 can be an annular rib to facilitate full contact with the outer surface of the outer ring 132, and the second mounting portion 1114 can also be an annular rib to facilitate full contact with the inner surface of the inner ring 131.

[0094] like Figure 14 and Figure 15 As shown, in some embodiments, a first supporting portion 1115 is protruded from the surface of the upper seat 1111 facing the lower seat 1112. The first supporting portion 1115 is connected to the top surface of the outer ring 132. The first supporting portion 1115 can space the inner ring 131 and the upper seat 1111 apart, thereby preventing friction between the upper seat 1111 and the inner ring 131. The first supporting portion 1115 can also stabilize the connection between the upper seat 1111 and the outer ring 132. A second supporting portion 1116 is protruded from the surface of the lower seat 1112 facing the upper seat 1111. The second supporting portion 1116 is connected to the bottom surface of the inner ring 131. The second supporting portion 1116 can space the outer ring 132 and the lower seat 1112 apart, thereby preventing friction between the outer ring 132 and the lower seat 1112. The second supporting portion 1116 can also stabilize the connection between the lower seat 1112 and the inner ring 131.

[0095] like Figure 14 and Figure 15 As shown, in some embodiments, a limiting groove 111b is provided on the surface of the lower seat 1112 facing away from the upper seat 1111, and a through hole 111c is provided on the bottom wall of the limiting groove 111b. The base 110 also includes a limiting member 115, and the limiting member 115 includes a limiting portion 1151 and a connecting portion 1152. The limiting portion 1151 is provided in the limiting groove 111b and is limitedly matched with the limiting groove 111b. The connecting portion 1152 passes through the through hole 111c and is connected to the upper seat 1111. The limiting portion 1151 is limitedly matched with the limiting groove 111b to prevent the upper seat 1111 from separating from the lower seat 1112. It should be noted that, under normal circumstances, the upper seat 1111 and the lower seat 1112 shell are connected by the rotating part 130, so the upper seat 1111 and the lower seat 1112 will not be easily separated, and the limiting portion 1151 and the limiting groove 111b are usually in a spaced-apart state, so that the limiting portion 1151 will not rub against the limiting groove 111b, and the limiting portion 1151 and the limiting groove 111b play a backup limiting effect.

[0096] like Figure 14 and Figure 15 As shown, in some embodiments, the through hole 111c is a circular hole, the outer contour of the connecting portion 1152 is cylindrical, and the side surface of the connecting portion 1152 is spaced apart from the side wall of the through hole 111c. This ensures that when the connecting portion 1152 rotates relative to the through hole 111c, the connecting portion 1152 does not rub against the side wall of the through hole 111c. When the upper seat 1111 deflects relative to the lower seat 1112, the connecting portion 1152 abuts against the side wall of the through hole 111c, thereby limiting the upper seat 1111 from further deflecting relative to the lower seat 1112, acting as a limiter, and thus protecting the upper seat 1111 and the lower seat 1112.

[0097] In some embodiments, the upper seat 1111 and the lower seat 1112 are spaced apart so that no friction occurs when the base 110 rotates with the lower seat 1112. Optionally, the gap between the upper seat 1111 and the lower seat 1112 can be as small as possible to reduce the probability of dust entering the base 110.

[0098] In some embodiments, base 110 also includes an anti-slip pad 116, which is disposed on the surface of lower base 1112 facing away from upper base 1111. This pad prevents slipping and stabilizes base 110. Furthermore, pad 116 covers the retaining groove, thereby reducing the risk of dust intrusion into base 110 and enhancing its aesthetics. The retaining member 115 is spaced apart from the anti-slip pad 116, ensuring that the retaining member 115 does not rub against the pad 116 during rotation.
