[0007] To further clarify the purpose, technical means, and advantages of this application, the application will be described in more detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are used solely for illustrative purposes and are not intended to limit this application.

[0008] As shown in Figure 1, an embodiment of this application provides a charging device 100. The charging device 100 is used to charge an external device. The external device may, for example, be a smartphone, a tablet computer, wireless earphones, a smartwatch, and the like.

[0009] The charging device 100 includes a base 110 and a rotating body 120.

[0010] The base 110 is used to support the rotating body 120. The rotating body 120 is hinged to the base 110. The axis of rotation of the rotating body 120 may be parallel to the horizontal direction, or parallel to the vertical direction, or somewhere between the horizontal and vertical directions, and is not limited thereto.

[0011] The rotating body 120 can support an external device, and as the rotating body 120 rotates, the angle of the charging device 100 changes, causing the external device to rotate in sync with the rotating body 120. This allows the angle of the external device to be adjusted, enabling the user to select the optimal angle for viewing the external device.

[0012] As shown in FIG. 2, in some embodiments, the base 110 includes a seat body 111 and a first arm 112. The shape of the seat body 111 may be exemplarily a flat plate shape, whereby the center of gravity of the base 110 can be made relatively low, and the stability is high when the base 110 is placed on a table. The shape of the first arm 112 may be exemplarily a rod shape, and relatively less material can be saved.

[0013] The first arm 112 is provided to protrude from the seat body 111 along the first direction A. The first direction A may be exemplarily a direction perpendicular to the base 110, or a direction inclined with respect to the base 110.

[0014] Optionally, the rotating body 120 is hinge-connected to the first arm 112, and the rotating body 120 is installed at a distance from the seat body 111. That is, the first arm 112 lifts the rotating body 120, and the rotating body 120 does not collide with the base 110 during rotation. Thus, the rotating body 120 has a relatively large rotation range.

[0015] Optionally, the end of the first arm 112 away from the base 110 is hinge-connected to the rotating body 120, whereby the length of the first arm 112 can be effectively utilized, and the first arm 112 can be made relatively short.

[0016] In some embodiments, the outer shape of the rotating body 120 may be a regular shape, whereby the design and manufacture of the rotating body 120 are facilitated, the space utilization efficiency is good, and the aesthetics are also excellent. Optionally, the outer shape of the rotating body 120 may be a cylindrical shape, a frustum of a cone shape, a cuboid shape, a cube shape, a spherical shape, etc.

[0017] As shown in FIG. 3, in some embodiments, a first rotating portion 1121 extending along the second direction B is provided on the first arm 112, and the first rotating portion 1121 is hinge-connected to the rotating body 120. The first direction A and the second direction B are arranged at an angle, that is, the first direction A and the second direction B are not parallel, and the angle formed by the first direction A and the second direction B is greater than 0 degrees and less than or equal to 90 degrees.

[0018] Optionally, the first rotating part 1121 is provided through the rotating main body 120, and the first rotating part 1121 is rotationally connected to the rotating main body 120, whereby the rotating main body 120 has two available ends.

[0019]

[0020] Hereinafter, an example in which the outer shape of the rotating main body 120 is cylindrical will be given for explanation. The rotating main body 120 has two opposite end faces and a side face connecting the two end faces, and the first rotating part 1121 is provided through the side face of the rotating main body 120. It should be understood that when the first rotating part 1121 is provided on one end face of the rotating main body 120, it may be difficult to install other functional modules on this end face due to the first rotating part 1121. However, in this embodiment, since the first rotating part 1121 is provided through the side face of the rotating main body 120, functional modules can be installed on both end faces of the rotating main body 120, and the two functional modules can follow the rotating main body 120 and adjust the angle.

[0021] As shown in FIG. 3, in some embodiments, the charging device 100 further includes a hovering member 160. The hovering member 160 can generate damping, that is, the hovering member 160 is used to provide a rotational torque for the rotating main body 120 relative to the first rotating part 1121, whereby the rotating main body 120 can hover an external device at a preset angle. Exemplarily, a first threshold value is determined based on the weight of a general external device. The first threshold value is the torque exerted by a general external device on the rotating device. By setting the torque of the hovering member 160 to be not less than the first threshold value, the gravity of the external device cannot overcome the torque of the hovering member 160, and the external device can hover at a preset angle. Of course, the first threshold value should not be too large. If it is too large, the user may feel difficult to rotate the rotating main body 120.

[0022] In some embodiments, the maximum rotation angle of the rotating body 120 is a preset angle, which can be set according to actual needs. For example, when the shape of the rotating body 120 is cylindrical, the preset angle is greater than 0 degrees and less than or equal to 360 degrees. Specifically, the preset angle may be 120 degrees. This allows the tilt angle of the rotating body 120 to cover everyday usage situations and prevents the external device from colliding with the seat 111 or the first arm 112 if the rotation angle of the external device is too large. Alternatively, the predetermined angle may be 360 ​​degrees. This allows the rotating body 120 to have a larger rotation range. Because the rotation range of the rotating body 120 is relatively large, external devices such as smartphones can be rotated from facing forward to facing backward, or from facing left to facing right, thereby widening the adjustment range when adjusting the angle.

[0022] In some embodiments, the charging device 100 further includes a drive unit, the output terminal of which is fixedly connected to the rotating body 120, and the drive unit rotates the rotating body 120. This eliminates the need for the user to manually adjust the angle of the rotating body 120, improving user comfort when using the charging device 100. Exemplarily, the drive unit may be a motor. Since the motor has self-locking properties, it can also be used to enable hovering of the rotating body 120.

[0023] As shown in Figure 4, in some embodiments, the hovering member 160 is provided between the rotating body 120 and the first rotating part 1121, preventing the rotating body 120 from rotating relative to the first rotating part 1121, and allowing the rotating body 120 to maintain hovering when no external force is acting, thereby maintaining a fixed angle. When an external force is acting, the rotating body 120 can rotate, thereby adjusting the support angle of the rotating body 120 relative to external equipment. In some other embodiments, the hovering member 160 can be provided between the rotating body 120 and the first arm 112, or between the rotating body 120 and the seat 111.

[0024] As shown in Figure 5, in some embodiments, the hovering member 160 includes a first connecting member 161, a second connecting member 162, and an adjustment member 163.

[0025] The first connecting member 161 is rotatably connected to the second connecting member 162 and is damped fit. The adjustment member 163 abuts against the second connecting member 162 and rotates together with the first connecting member 161. This provides a constant torque (i.e., damping) when the first connecting member 161 rotates relative to the second connecting member 162. The hovering member 160 provides torque and can also act as a rotating member between the first arm 112 and the rotating body 120, thereby reducing wear between the first arm 112 and the rotating body 120.

[0026] The adjustment member 163 is connected to both the first connecting member 161 and the second connecting member 162, and is used to adjust the force acting between the first connecting member 161 and the second connecting member 162, thereby changing the torque of the hovering member 160. The user can adjust the torque of the hovering member 160 according to their needs. When the torque of the hovering member 160 is relatively large, the rotating body 120 becomes relatively difficult to rotate, thereby enabling it to support heavier external devices. When the torque of the hovering member 160 is relatively small, the user can rotate the rotating body 120 with relatively little force, making the rotating body 120 suitable for supporting lighter external devices. The torque of the hovering member 160 in this embodiment of the application is adjustable, thereby accommodating different user habits.

[0027] As an example, as shown in Figures 5 and 6, one end of the first connecting member 161 is fixedly connected to the first rotating part 1121, the other end of the first connecting member 161 is provided with a male thread, and a contact part 1611 is provided in the center of the first connecting member 161. The adjustment member 163 is provided with a female thread, and the female thread of the adjustment member 163 is screwed into the male thread of the first connecting member 161. For example, the adjustment member 163 may be a nut.

[0028] The second connecting member 162 includes a sleeve 1621 and a torque pad (not shown) provided within the sleeve 1621. Both the sleeve 1621 and the torque pad are fitted onto the first connecting member 161, and both are positioned between the contact portion 1611 and the adjustment 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 torque pad rotates together with the first connecting member 161. Torque is generated between the torque pad and the sleeve 1621, and the adjustment member 163 can rotate relative to the first connecting member 161, thereby adjusting the pressure between the torque pad and the sleeve 1621 and adjusting the torque between the torque pad and the sleeve 1621. The greater the force acting between the torque pad and the sleeve 1621, the greater the torque of the hovering member 160, and the smaller the force acting between the torque pad and the sleeve 1621, the smaller the torque of the hovering member 160.

[0029] In some other embodiments, the hovering member 160 may consist only of a rubber ring, which is positioned between the first rotating part 1121 and the rotating body 120 and is used to increase the rotational resistance between the first arm 112 and the rotating body 120, thereby providing torque and allowing for a relatively simple structure of the charging device 100.

[0030] Of course, the charging device 100 does not have to include the hovering member 160. The first rotating part 1121 and the rotating main body 120 are hinged together by an interference fit, and torque is provided by the frictional force between the first rotating part 1121 and the rotating main body 120, which further simplifies the structure of the charging device 100.

[0031] In some embodiments, a mounting groove 112b is provided on the side of the first arm 112 away from the first rotating portion 1121, and the second connecting member 162 is fixed to the mounting groove 112b. The bottom wall of the mounting groove 112b restricts the movement of the second connecting member 162 along the first direction A, and the side walls of the mounting groove 112b restrict the rotation of the second connecting member 162 along the rotation direction of the rotating body 120. Exemplarily, the mounting groove 112b may be a hexagonal groove, and the shape of the second connecting member 162 may also be hexagonal, thereby allowing the mounting groove 112b to restrict the rotation of the second connecting member 162. Of course, the mounting groove 112b may also be a non-circular groove such as a triangular groove or a square groove, as long as the shape of the second connecting member 162 corresponds to the shape of the mounting groove 112b.

[0032] In some embodiments, the hovering member 160 includes a first buckle and a first bearing, the first buckle being fixedly connected to a first rotating part 1121, the first bearing being fixedly connected to a rotating body 120, the first bearing being fitted into the first buckle and rotatably connected to the first buckle. By providing the first buckle and the first bearing, friction between the first rotating part 1121 and the rotating body 120 can be reduced, thereby improving the service life.

[0033] Selectively, damping oil can be provided between the first buckle and the first bearing, thereby creating rotational torque between the first buckle and the first bearing and achieving a hovering effect. Alternatively, the hovering effect can be achieved by interference fitting the first buckle and the first bearing.

[0034] As shown in Figure 3, in some embodiments, the charging device 100 further includes a second arm 113, which may be rod-shaped, thereby saving material. The second arm 113 is provided projecting from the seat 111 along a third direction C, which may be the same as or different from the first direction A, and may be perpendicular to the base 110, or inclined with respect to the base 110.

[0035] The second arm 113 is provided at a distance from the first arm 112, and the rotating body 120 is simultaneously hinged to both the first arm 112 and the second arm 113. That is, the axis of rotation between the rotating body 120 and the first arm 112, and the axis of rotation between the rotating body 120 and the second arm 113 are on the same straight line. By providing the second arm 113, both sides of the rotating body 120 are supported, and the force applied to both sides of the rotating body 120 is relatively uniform. As a result, the connection strength between the rotating body 120 and the seat 111 is improved, the rotating body 120 can support heavier external devices, and is more stable during rotation.

[0036] As shown in Figure 3, the second arm 113 extends along the fourth direction D, forming the second rotating section 1131. The second rotating section 1131 is hinged to the rotating body 120, and the fourth direction D is opposite to the second direction B. That is, the second rotating section 1131 is positioned opposite the first rotating section 1121, and the rotating body 120 is located between the second rotating section 1131 and the first rotating section 1121. The second rotating section 1131 and the first rotating section 1121 can jointly position the rotating body 120, thereby making it less likely for the rotating body 120 to fall out from between the first arm 112 and the second arm 113.

[0037] Selectively, the second rotating part 1131 is provided through the rotating body 120, and the rotating body 120 is located between the first rotating part 1121 and the second rotating part 1131, and is hinged to both the first rotating part 1121 and the second rotating part 1131 simultaneously.

[0038] As shown in Figures 6 and 7, in some embodiments, the rotating body 120 is provided with a coaxial first rotation hole 120a and a second rotation hole 120b, the first rotating part 1121 is rotatably mounted in the first rotation hole 120a, and the second rotating part 1131 is rotatably mounted in the second rotation hole 120b. In other embodiments, the positions of the rotation holes and the rotating parts can be swapped, that is, the first rotation hole 120a can be provided in the first arm 112, the second rotation hole 120b can be provided in the second arm 113, and both the first rotating part 1121 and the second rotating part 1131 can be provided in the rotating body 120.

[0039] Generally, the first rotating part 1121 is more susceptible to damage than the first rotating hole 120a. Similarly, the second rotating part 1131 is more susceptible to damage than the second rotating hole 120b. In this embodiment, the first rotating part 1121 is provided on the first arm 112, and the second rotating part 1131 is provided on the second arm 113. If the first rotating part 1121 or the second rotating part 1131 is damaged, since both the light-emitting module 150 and the wireless charging module 140 are provided on the rotating body 120, it is easier and less costly to replace the first arm 112 or the second arm 113 than to replace the rotating body 120.

[0040] As shown in Figure 6, in some embodiments, the first connecting member 161 can extend through the first rotation hole 120a into the interior of the rotating body 120 so as to be fixedly connected to the internal structure of the rotating body 120. This improves the connection strength between the second connecting member 162 and the rotating body 120. Selectively, the first rotation hole 120a may be a blind hole, and a positioning hole may be provided in the bottom wall of the first rotation hole 120a, with the end of the first connecting member 161 away from the adjustment member 163 extending through the positioning hole into the interior of the rotating body 120. The shape of the positioning hole may be rectangular, and the shape of the end of the second connecting member 162 away from the adjustment member 163 may be plate-shaped to match the positioning hole, thereby allowing the second connecting member 162 and the rotating body 120 to have a position limiting fit in the rotational direction, and allowing the second connecting member 162 to rotate synchronously with the rotating body 120.

[0041] As shown in Figure 6, in some embodiments, a first positioning projection 121 is provided on one of the first rotating portion 1121 and the hole wall of the first rotating hole 120a, and a first positioning groove 112a is provided on the other of the first rotating portion 1121 and the first rotating hole 120a. The first positioning projection 121 is slidably mounted along the first positioning groove 112a, and the first positioning projection 121 and the first positioning groove 112a are position-fitted to limit the rotation angle of the rotating body 120 relative to the first arm 112.

[0042] For example, the first rotating part 1121 is provided with a first positioning groove 112a, and the first rotating hole 120a is provided with a first positioning projection 121. The shape of the first positioning groove 112a is arc-shaped, and when the rotating body 120 rotates, the first positioning projection 121 rotates synchronously and slides within the first positioning groove 112a. When the first positioning projection 121 comes into contact with the end of the first positioning groove 112a, the first positioning projection 121 is unable to continue rotating, thereby limiting the rotation of the rotating body 120. It should be understood that if an external device such as a smartphone is relatively large and is fixed to the rotating body 120 and rotates with it, the smartphone may collide with the base 110, the first arm 112, or the second arm 113. By providing the first positioning projection 121, the rotation angle of the rotating body 120 can be limited, thereby preventing large external devices such as smartphones from colliding with the base 110, the first arm 112, or the second arm 113, and improving safety.

[0043] As shown in Figure 6, in some embodiments, the first positioning projection 121 abuts against both side walls of the first positioning groove 112a in the rotational direction of the rotating body 120 to restrict the rotation of the rotating body 120. The rotational range of the rotating body 120 is defined by the difference in dimensions between the first positioning projection 121 and the first positioning groove 112a in the rotational direction of the rotating body 120.

[0044] As shown in Figure 7, in some embodiments, a second positioning projection 122 is provided on one side of the second rotating portion 1131 and the hole wall of the second rotating hole 120b, and a second positioning groove 113a is provided on the other side of the second rotating portion 1131 and the second rotating hole 120b. The second positioning projection 122 is slidably mounted in the second positioning groove 113a, and the second positioning projection 122 and the second positioning groove 113a are position-fitted to limit the rotation angle of the rotating body 120 relative to the second arm 113.

[0045] For example, the second rotating part 1131 is provided with a second positioning groove 113a, and the second rotating hole 120b is provided with a second positioning projection 122. The shape of the second positioning groove 113a is arc-shaped, and when the rotating body 120 rotates, the second positioning projection 122 rotates synchronously and slides within the second positioning groove 113a. When the second positioning projection 122 comes into contact with the end of the second positioning groove 113a, the second positioning projection 122 cannot continue to rotate, thereby achieving positioning relative to the rotating body 120. It should be understood that external devices such as smartphones are relatively large, and when a smartphone is fixed to the rotating body 120 and rotates with the rotating body 120, there is a possibility that the smartphone may collide with the base 110, the first arm 112, or the second arm 113. By providing the second positioning projection 122, the rotation angle of the rotating body 120 can be limited, preventing large external devices such as smartphones from colliding with the base 110, the first arm 112, or the second arm 113, thereby improving safety.

[0046] As shown in Figures 6 and 7, in some embodiments, the first positioning projection 121, the first positioning groove 112a, the second positioning projection 122, and the second positioning groove 113a can be provided simultaneously, thereby allowing the first positioning projection 121 and the second positioning projection 122 to be positioned simultaneously with respect to the rotating body 120, improving the positioning effect. Furthermore, when both sides of the rotating body 120 are positioned, they receive force simultaneously, resulting in relatively uniform force distribution.

[0047] As shown in Figure 7, in some embodiments, the second positioning projection 122 abuts against both side walls of the second positioning groove 113a in the rotational direction of the rotating body 120, thereby restricting the rotation of the rotating body 120. The rotational range of the rotating body 120 is defined by the difference in dimensions between the second positioning projection 122 and the second positioning groove 113a in the rotational direction of the rotating body 120.

[0048] In some embodiments, a second positioning projection 122 is provided on the wall of the second rotation hole 120b, and 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 rotating part 1131, and the other end of the second buckle 170 passes 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, and the second bearing 220 is fitted onto the second buckle 170 and rotatably connected to the second buckle 170. The second buckle 170 is positioned between the flange 171 and the second positioning projection 122, and the flange 171 and the second positioning projection 122 jointly position the second buckle 170, thereby preventing the second buckle 170 from falling off the second bearing 220. The structures of the first buckle and first bearing described above can be referenced to the second buckle 170 and second bearing 220.

[0049] As shown in Figures 8 and 9, in some embodiments, the second rotating portion 1131 is a hollow structure, and the outer wall of the second buckle 170 is fitted closely to the inner wall of the second rotating portion 1131. A positioning hole 170a is provided on one of the outer walls of the second buckle 170 and the inner wall of the second rotating portion 1131, and a third positioning projection 123 is provided on the other of the outer wall of the second buckle 170 and the inner wall of the second rotating portion 1131. The positioning hole 170a and the third positioning projection 123 are position-fitted, thereby restricting the second buckle 170 from moving along the second direction B or the fourth direction D, and from rotating relative to the second arm 113.

[0050] For example, the outer wall of the second buckle 170 is provided with a positioning hole 170a, and the inner wall of the second rotating part 1131 is provided with a third positioning projection 123. When assembling the second buckle 170 to the second arm 113, the assembly is completed simply and quickly by directly inserting the second buckle 170 into the second rotating part 1131 until the third positioning projection 123 and the positioning hole 170a are in a positional fit. The second buckle 170 and the second arm 113 do not need to be fixed with other parts, resulting in a relatively simple structure and low cost. Selectively, the second buckle 170 and the second rotating part 1131 can also be fitted in an interference fit, which can further improve the positioning effect of the second buckle 170 and the second rotating part 1131.

[0051] As shown in Figure 10, in some embodiments, the charging device 100 further includes a counterweight block 114. The counterweight block 114 is provided within the seat 111, thereby further lowering the center of gravity of the base 110 and increasing the stability of the charging device 100.

[0052] As shown in Figure 1, in some embodiments, the charging device 100 further includes a wireless charging module 140. The wireless charging module 140 is mounted on the rotating body 120 and is for charging an external device.

[0053] As shown in Figures 2 and 4, the wireless charging module 140 includes a coil 141, a main control board 142, a magnetic shielding piece 143, and a magnet 144. The main control board 142 is electrically connected to the coil 141 and controls the transmission of electromagnetic signals by the coil 141. A receiving coil in an external device receives this electromagnetic signal and performs charging by converting it into an electric current.

[0054] The magnetic shielding piece 143 is placed between the main control board 142 and the coil 141. The magnetic shielding piece 143 can reflect electromagnetic signals, thereby preventing the electromagnetic signals from propagating to external devices and from affecting the main control board 142.

[0055] The magnet 144 is positioned around the coil 141. The magnet 144 can attract external devices, which aligns the external devices with the wireless charging module 140, reducing misalignment and improving charging efficiency.

[0056] As shown in Figure 4, in some embodiments, the charging device 100 further includes a light-emitting module 150. The light-emitting module 150 is positioned on a rotating body 120, and a light-transmitting section is provided at the position of the rotating body 120 corresponding to the light-emitting module 150. The light-emitting module 150 can illuminate the surrounding environment and functions as a desk lamp, night light, or ambient lighting. When a user uses a mobile phone in a dark place, the light-emitting module 150 reduces the brightness difference between the mobile phone screen and the surrounding environment, protecting the user's eyes. As the rotating body 120 rotates, the light-emitting module 150 rotates with the rotating body 120, meaning the light-emitting module 150 can adjust its angle, thereby allowing the light-emitting module 150 to illuminate different positions, making it more convenient to use.

[0057] As shown in Figure 4, in some embodiments, the rotating body 120 has a first end 125 and a second end 126 positioned opposite each other, a wireless charging module 140 is located at the first end 125, and the charging device 100 further includes a light-emitting module 150, which is located at the second end 126. The wireless charging module 140 and the light-emitting module 150 may be the two functional modules described above. Selectively, the rotating body 120 is hinged to a first arm 112 at an intermediate position between the first end 125 and the second end 126, thereby making the first arm 112 relatively shorter, resulting in a more balanced load distribution between the first end 125 and the second end 126 of the rotating body 120, and reducing the centrifugal force during rotation of the rotating body 120.

[0058] As shown in Figure 4, in some embodiments, the light-emitting module 150 is positioned away from the wireless charging module 140, meaning that the light emitted from the light-emitting module 150 is directed away from the wireless charging module 140. Normally, when a smartphone is placed on the wireless charging module 140 for charging, the smartphone screen faces the user. Because the light emitted from the light-emitting module 150 is directed away from the wireless charging module 140, the light-emitting module 150 is not directed at the user, thus preventing the light-emitting module 150 from irritating the user's eyes. The rotating body 120 can rotate both the wireless charging module 140 and the light-emitting module 150, thereby simplifying the structure of the charging device 100 and reducing costs.

[0059] As shown in Figure 4, in some embodiments, the light-emitting module 150 includes a lamp substrate 151, on which multiple LED lamps are provided. The LED lamps have high brightness, low power consumption, and a long lifespan. Selectively, the lamp substrate 151 is provided with a reflective coating, which reflects light, thereby concentrating the light from the lamp substrate 151 and improving brightness.

[0060] As shown in Figure 4, in some embodiments, a plug-in portion 1421 is provided on one of the lamp board 151 and the main control board 142, and an engagement portion 1511 is provided on the other of the lamp board 151 and the main control board 142. The lamp board 151 and the main control board 142 are assembled by plugging the plug-in portion 1421 and the engagement portion 1511 into each other. Exemplarily, the plug-in portion 1421 is a pin header and the engagement portion 1511 is a female header, or the plug-in portion 1421 is a male terminal of a flat cable and the engagement portion 1511 is a female terminal of a flat cable. The main control board 142 is used to supply power to the lamp board 151 and to drive and light up multiple LED lamps and change the color temperature.

[0061] As shown in Figure 4, in some embodiments, the light-emitting module 150 is located inside the rotating body 120, allowing the rotating body 120 to perform a light-concentrating effect. This concentrates the light emitted from the light-emitting module 150, improving its directivity. Selectively, the rotating body 120 includes a translucent cover 124 installed at the second end 126. The translucent cover 124 has a light-transmitting portion. The light-emitting module 150 is positioned at a distance from the translucent cover 124, allowing the translucent cover 124 to perform a light-transmitting effect, and the light emitted from the light-emitting module 150 can be transmitted through the translucent cover 124 to the outside of the rotating body 120. Selectively, the translucent cover 124 is semi-transparent, also serving to enhance the uniformity of the light.

[0062] As shown in Figure 4, in some embodiments, the light-emitting module 150 further includes a light-leveling cover 152. The light-leveling cover 152 is placed on the lamp substrate 151 and has the effect of further homogenizing the light.

[0063] As shown in Figure 10, in some embodiments, the charging device 100 further includes an operating module 190. The operating module 190 is located in the seat 111. Since the seat 111 is normally stationary, rotation of the rotating body 120 to different angles does not affect the user's operation of the operating module 190. The operating module 190 is also electrically connected to the light-emitting module 150, and can be used to adjust the color temperature of the light-emitting module 150, or to adjust the brightness of the light-emitting module 150, or to adjust both the color temperature and brightness of the light-emitting module 150 simultaneously. The operating module 190 may be touch-sensitive. Since the operating module 190 is located inside the seat 111, it is protected and its service life is extended. Because the light-emitting module 150 can be operated by touching the surface of the seat 111, the seat 111 is well-sealed and aesthetically pleasing. Alternatively, the operating module 190 may be a button type or a knob type, and is not limited to these.

[0064] In some embodiments, the charging device 100 further includes a rechargeable battery. The rechargeable battery is located inside the rotating body 120 or the seat 111 and is electrically connected to both 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. This allows the charging device 100 to provide illumination and charging without being connected to an external power source, and allows the user to easily move the charging device 100 at any time.

[0065] As shown in Figure 10, in some embodiments, the charging device 100 further includes a connection terminal 180. The connection terminal 180 is provided on the base 111 and is electrically connected to both the wireless charging module 140 and the light-emitting module 150, supplying power to the wireless charging module 140 and the light-emitting module 150.

[0066] The connection terminal 180 is used to connect a power cable, which supplies power to the charging device 100 via the connection terminal 180. For example, the type of connection terminal 180 may be a relatively common type-C interface. The connection terminal 180 is provided on the seat 111, and since the seat 111 is normally stationary when the charging device 100 is in use, the power supply cable is also stationary, resulting in more stable power supply.

[0067] As shown in Figures 11 and 12, in some embodiments, a first mounting cavity 111a is provided inside the seat body 111, and a first wiring passage 113b communicating with the first mounting cavity 111a is formed inside the first arm 112. A second mounting cavity 120c is provided inside the rotating body 120, and a second wiring passage 170b is formed inside the second rotating part 1131, with the second wiring passage 170b communicating with the first wiring passage 113b and the second mounting cavity 120c.

[0068] Since the first mounting cavity 111a, the first wiring passage 113b, the second wiring passage 170b, and the second mounting cavity 120c are sequentially connected, the electrical components in the base 110 and the electrical components in the rotating body 120 can be electrically connected via the conductor 210, and since the conductor 210 is not exposed to the outside of the charging device 100, it is highly safe and aesthetically pleasing.

[0069] For example, the conductor 210 can be connected to the operation module 190 and the light-emitting module 150. The conductor 210 extends from the first mounting cavity 111a through the first wiring passage 113b and the second wiring passage 170b to the second mounting cavity 120c, and the conductor 210 can supply power to the operation module 190 and the wireless charging module 140. The operation module 190 can control the light-emitting module 150 via the conductor 210.

[0070] In some embodiments, the charging device 100 further includes a positioning member. The positioning member is provided on the rotating body 120 or the wireless charging module 140 and is used to position an external device. The positioning member may also be a clamping member, which is provided on the rotating body 120 and can fix the external device by clamping. Alternatively, the positioning member may be a magnet 144, which is fixed to the external device by magnetic attraction and can be integrated into the wireless charging module 140. When the rotating body 120 rotates, the positioning member and the external device fixed to the positioning member rotate together with the rotating body 120, allowing the angle of the external device to be adjusted. In other words, the rotating body 120 functions as a stand.

[0071] The wireless charging module 140 can be installed in conjunction with a positioning member, and when an external device is positionally fitted to the positioning member, 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, if the wireless charging module 140 is installed near a positioning member and the external device is fixed to the positioning member, the relative distance between the wireless charging module 140 and the external device becomes smaller, enabling charging of the external device or increasing the charging efficiency.

[0072] In some embodiments, the first arm 112 is hinged to the seat 111, and the axis of rotation of the first arm 112 is positioned at an angle to the axis of rotation of the rotating body 120, so that the rotating body 120 has rotational degrees of freedom in two directions and improved rotational flexibility. That is, the rotating body 120 rotates about a first axis E, and the first axis E is parallel to the first direction A. The first arm 112 rotates about a second axis F, and the first axis E and the second axis F are positioned at an angle, and 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.

[0073] As shown in Figure 13, in some embodiments, the seat 111 includes an upper seat 1111 and a lower seat 1112, which are rotatably connected about a third axis G. The third axis G is positioned at an angle with the first axis E, and the rotating body 120 has rotational degrees of freedom in two directions, improving rotational flexibility. 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.

[0074] As shown in Figure 13, in some embodiments, the first arm 112 is hinged to the base 111 around the second axis F, and the upper base 1111 and lower base 1112 are rotatably connected around the third axis G. The first axis E and the second axis F are positioned to form an angle with the third axis G, thereby giving the rotating member 130 rotational degrees of freedom in three directions and improving rotational flexibility. Exemplarily, the rotating body 120 can swing back and forth, the first arm 112 can swing left and right, and the base 110 can rotate horizontally, so that the rotating body 120 can be adjusted in any direction in three-dimensional space. 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.

[0075] As shown in Figures 14 and 15, in some embodiments, the charging device 100 further includes a rotating member 130. The rotating member 130 includes an inner ring 131 and an outer ring 132, with the inner ring 131 rotatably connected to the outer ring 132. 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. Thus, the lower seat 1112 and the upper seat 1111 are rotatably connected via the rotating member 130. By providing the rotating member 130, wear between the inner ring 131 and the outer ring 132 can be reduced, improving the service life of the inner ring 131 and the outer ring 132, and the rotation of the inner ring 131 and the outer ring 132 can be made smoother by reducing frictional force.

[0076] Selectively, lubricating oil or rolling elements can be provided between the inner ring 131 and the outer ring 132, thereby making the rotation of the inner ring 131 and the outer ring 132 smoother. Exemplarily, the rotating member 130 may be a ball bearing.

[0077] As shown in Figures 14 and 15, in some embodiments, the first mounting portion 1113 is provided projecting from the surface of the upper seat 1111 facing the lower seat 1112, and the second mounting portion 1114 is provided projecting 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. Exemplarily, the first mounting portion 1113 may be an annular rib so as to make sufficient contact with the outer surface of the outer ring 132. The second mounting portion 1114 may be an annular rib so as to make sufficient contact with the inner surface of the inner ring 131.

[0078] As shown in Figures 14 and 15, in some embodiments, the first support portion 1115 is provided protruding from the surface of the upper seat 1111 facing the lower seat 1112, and the first support portion 1115 is connected to the upper surface of the outer ring 132. The first support portion 1115 causes the inner ring 131 to be positioned at a distance from the upper seat 1111, preventing friction between the upper seat 1111 and the inner ring 131, and the first support portion 1115 makes the connection between the upper seat 1111 and the outer ring 132 more stable. The second support portion 1116 is provided protruding from the surface of the lower seat 1112 facing the upper seat 1111, and the second support portion 1116 is connected to the bottom surface of the inner ring 131. The second support portion 1116 positions the outer ring 132 at a distance from the lower base 1112, preventing friction between the outer ring 132 and the lower base 1112, and also provides a more stable connection between the lower base 1112 and the inner ring 131.

[0079] As shown in Figures 14 and 15, in some embodiments, a positioning recess 111b is provided on the surface of the lower seat 1112 opposite to the upper seat 1111, and a through hole 111c is provided in the bottom wall of the positioning recess 111b. The bottom seat 110 further includes a positioning member 115, which includes a positioning portion 1151 and a connecting portion 1152. The positioning portion 1151 is provided in the positioning recess 111b and is position-fitted with the positioning recess 111b. The connecting portion 1152 is connected to the upper seat 1111 through the through hole 111c. By position-fitting the positioning portion 1151 with the positioning recess 111b, separation of the upper seat 1111 and the lower seat 1112 can be prevented. Normally, the upper seat 1111 and the lower seat 1112 are connected via a rotating member 130, so they cannot be easily separated. The positioning portion 1151 and the positioning recess 111b are usually spaced apart, thereby preventing the positioning portion 1151 from rubbing against the positioning recess 111b, and the positioning portion 1151 and the positioning recess 111b perform a preliminary positioning function.

[0080] As shown in Figures 14 and 15, in some embodiments, the through hole 111c is a circular hole, and the outer shape of the connecting portion 1152 is cylindrical. The side surface of the connecting portion 1152 and the side wall of the through hole 111c are spaced apart so that the connecting portion 1152 does not rub against the side wall of the through hole 111c when the connecting portion 1152 rotates relative to the through hole 111c. When the upper seat 1111 is tilted relative to the lower seat 1112, the connecting portion 1152 comes into contact with the side wall of the through hole 111c, thereby limiting the upper seat 1111 from continuing to tilt further relative to the lower seat 1112, and functions as a positioning element to protect the upper seat 1111 and the lower seat 1112.

[0081] In some embodiments, the upper seat 1111 and the lower seat 1112 are spaced apart so that friction does not occur when the base seat 110 and the lower seat 1112 rotate. Selectively, the gap between the upper seat 1111 and the lower seat 1112 can be made as small as possible, thereby reducing the possibility of dust entering the base seat 110.

[0082] In some embodiments, the base 110 further includes an anti-slip pad 116, which is provided on the surface of the lower base 1112 opposite to the upper base 1111. The anti-slip pad 116 provides an anti-slip function and improves the stability of the base 110. In addition, by covering the positioning recess, the anti-slip pad 116 reduces the risk of dust entering the base 110 and improves the aesthetics. The positioning member 115 is positioned at a distance from the anti-slip pad 116 so that the positioning member 115 does not experience friction with the anti-slip pad 116 when it rotates.
