As shown in the figures, the charging stand 1 of the present invention is a desktop charging stand or a wall charging stand, which is installed at a fixed position having a surface such as a desk or a wall, and is used to charge a mobile terminal device, for example, charging a wireless device 6 and / or a power receiving terminal 7 of a wired device. The charging stand 1 includes a base 2 and a power supply unit 3. The base 2 is installed on a desk or a wall, and includes a base surface 21 and a recess 22, and the recess 22 is formed by recessing the base surface 21 inward. The power supply unit 3 is installed on the base 2 and includes a power supply unit main body 32 and a mounting portion 31 .

[0009] The power supply unit main body 32 is at least partially installed in the recess 22 of the base 2, and includes two charging terminals 33, a wired power transmission module 34, and a wireless power transmission module 35. FIG. 1 shows the wired power transmission module 34 and the wireless power transmission module 35, and for the sake of simplicity, the wired power transmission module 34 and the wireless power transmission module 35 are omitted in FIGS. 2 to 5. As shown in FIGS. 1 and 4, each charging terminal 33 is a type-C charging terminal connected to a power receiving terminal 7 of a wired device. The wired power transmission module 34 supplies power to the two charging terminals 33, thereby charging the wired device via the charging terminals 33. 2 and 5, the mounting part 31 is installed on one side of the power supply unit main body 32 away from the recess 22 of the base 2, one side of the mounting part 31 contacts the base surface 21, and the mounting part 31 has a mounting part surface 311 and a mounting part bottom surface 312, and the mounting part surface 311 of the mounting part 31 is used to mount the wireless device 6 as shown in Fig. 5. As shown in Fig. 1, the wireless power transmission module 35 is adjacent to the mounting part bottom surface 312 of the mounting part 31, and when the wireless device 6 is placed on the mounting part surface 311 of the mounting part 31, the wireless power transmission module 35 wirelessly charges the wireless device 6 via the mounting part 31 (as shown in Fig. 5).

[0010] One side of the placement part 31 that contacts the base surface 21 has a rotation axis, and when the placement part surface 311 of the placement part 31 receives an external force, the placement part 31 can rotate around the rotation axis. For example, the placement part 31 rotates in a direction away from the recess 22 of the base 2 according to the rotation axis, forming an included angle between the placement part 31 and the base surface 21 of the base 2. As shown in Figs. 1 and 2, the placement part 31 rotates the power supply part main body 32 connected to the placement part 31 in a direction away from the recess 22 of the base 2 to expose two charging terminals 33, and the power supply part 3 is in an open state. In this configuration, the charging stand 1 can charge the wireless device 6 placed on the placement part surface 311 of the placement part 31 via the wireless power transmission module 35 (as shown in Fig. 5), and can charge the wired device inserted into the charging terminal 34 via the wired power transmission module 34 (as shown in Fig. 4). When the mounting portion 31 rotates along the rotation axis toward the recess 22 of the base 2, the mounting portion 31 and the base surface 21 of the base 2 are on the same plane, and as shown in FIG. 3, the mounting portion 31 rotates the power supply unit main body 32 connected to the mounting portion 31 toward the recess 22 of the base 2 to accommodate the power supply unit main body 32 in the recess 22 of the base 2, hiding the two charging terminals 33, and the power supply unit 3 is in a closed state. In this configuration, the charging stand 1 can charge the wireless device 6 placed on the mounting portion surface 311 of the mounting portion 31 via the wireless power transmission module 35. In one embodiment, as shown in FIG. 3, when the mounting portion 31 rotates along the rotation axis toward the recess 22 of the base 2, the mounting portion 31 is accommodated in the recess 22 of the base 2, and the surface of the mounting portion 31 and the base surface 21 of the base 2 are located on the same plane.

[0011] As can be seen from the above, the charging stand 1 of the present invention includes a power supply unit 3, and the power supply unit main body 32 of the power supply unit 3 includes a wired power transmission module 34 and a wireless power transmission module 35. When a user requires only wireless charging, the power supply unit 3 can be closed by an external force, and the charging stand 1 can charge the wireless device 6 placed on the placement surface 311 of the placement unit 31 via the wireless power transmission module 35. When a user requires both wireless charging and wired charging, the power supply unit 3 can be opened by an external force, and the charging stand 1 can charge the wireless device 6 placed on the placement surface 311 of the placement unit 31 via the wireless power transmission module 35 and charge the wired device inserted into the charging terminal 34 via the wired power transmission module 34. Therefore, compared with a conventional charging stand that requires the use of a power output cable for charging, the charging stand 1 of the present invention can select wireless charging or wired charging as needed, and the convenience of the charging stand 1 of the present invention is increased.

[0012] In order to fix the wireless device 6 to the mounting part 31, in some embodiments, the wireless power transmission module 35 has a magnetic adsorption function, whereby the wireless power transmission module 35 uses the magnetic adsorption function to fix the wireless device 6 having a magnetic force to the mounting surface 311 of the mounting part 31. In some embodiments, the base surface 21 of the base 2 has a stopper wall 211, and as shown in Figs. 2 and 5, when the power supply unit 3 is in an open state, i.e., when there is an included angle between the mounting part 31 and the base surface 21 of the base 2, the stopper wall 211 protrudes from the base surface 21 to prevent the wireless device 6 from slipping when the wireless device 6 is placed on the mounting surface 311 of the mounting part 31. As shown in FIG. 3, when the power supply unit 3 is in a closed state, that is, when the mounting portion 31 and the base surface 21 of the base 2 are on the same plane and the mounting portion 31 is housed in the recess 22 of the base 2, the stopper wall 211 is housed in the base 2 and the surface of the stopper wall 211 and the base surface 21 of the base 2 are on the same plane, so that the wireless device 6 can be placed flat on the mounting portion surface 311 of the mounting portion 31.
