[0030] Please see Figures 1-5 In this embodiment of the utility model, a rechargeable desk lamp includes a base 1 and a lampshade 2. A connecting rod 3 is provided on the end face of the base 1 for connecting the lampshade 2. A bulb 4 is disposed inside the lampshade 2. A power supply module is disposed inside the base 1. The power supply module includes a power plug 51, a control board 52 for outputting appropriate current to the bulb 4 and the power plug 51, and a data plug 53. The base 1 has a first through hole 11, through which the power plug 51 is electrically connected to the control board 52 and extends. The base 1 also has at least two second through holes 12, and at least two data plugs 53 are correspondingly disposed inside the base 1. The data plugs 53 are electrically connected to the control board 52. One end of the data plug 53 for connecting electronic devices extends from the second through hole 12, and the other end of the data plug 53 is retractably installed inside the base 1. The lampshade 2 has an internal hollow structure. The control board 52 has a voltage conversion function, capable of providing appropriate voltage to the bulb 4 or the device to be charged, including but not limited to mobile phones, tablets, laptops, smartwatches, etc. Figure 4As shown, the data plug 53 includes, but is not limited to, Type-C and Lightning interfaces. For example, the data plug 53 can be equipped with Micro-USB, Magsafe, and Mini USB interfaces.

[0031] Specifically, the shape of the base 1 includes, but is not limited to, circles and rhombuses. The base 1 has an internal hollow structure and includes an upper cover (not shown in the figure) and a lower cover (not shown in the figure). After the power supply module and power plug are installed inside the base, the lower cover is installed at the lower end of the upper cover by means of threaded connection or snap-fit ​​connection.

[0032] In another embodiment of this utility model, the control board 52 includes a rectifier bridge, a filter capacitor, a switching power supply chip, and a high-voltage transformer. The input terminal of the rectifier bridge is connected to an AC power supply, and the output terminal is connected to the filter capacitor. The AC input (e.g., 220V AC) is converted into DC power. Through high-frequency switching control, the high-voltage DC power is stepped down to low-voltage DC power (e.g., 12V / 5V). A DC-DC step-down chip and a USB protocol chip are provided. The DC-DC step-down chip is used to step down the 12V output from the secondary side to the low voltage required by the desk lamp. The USB protocol chip is used to identify the device charging protocol (e.g., PD / QC) and dynamically adjust the output voltage (e.g., 5V / 9V / 12V).

[0033] The working principle of this embodiment is as follows: Two sets of retractable data plugs 53 are installed inside the base 1 of the desk lamp. During use, the data plugs 53 can be stretched. After the charging device is fully charged, the data plugs 53 can retract into the base 1. The data plugs 53 can achieve the retractable effect by setting a telescopic device, such as a reel 14. By installing the reel 14 inside the base 1, the data plugs 53 are wound into the reel 14. The end of the data plug 53 used for power supply extends out from the second through hole 12. In some embodiments, the reel 14 includes a spiral spring, a spool, and a locking mechanism. The locking mechanism fixes the pulled-out length by a ratchet or a buckle (such as the pause button in a tape measure). When the user pulls out the data plug 53, the spool rotates, causing the spiral spring to tighten and store energy. When the user releases the data plug 53, the spring releases energy, driving the spool to reverse and retract the data plug 53.

[0034] Further as Figures 1-4 As shown in the embodiment of this utility model, the power supply module further includes a data port 54, which is electrically connected to the control board 52. The base 1 has at least one third through hole 13, which corresponds to the data plug 53. The data port 54 is inserted into the third through hole 13. The data port 54 includes, but is not limited to, a Type-C port and a Lightning port. In some embodiments, the data plug 53 can be a Micro-USB port, a MagSafe port, or a Mini USB port.

[0035] like Figure 4 As shown, in another embodiment of this utility model, the base 1 is provided with two data ports 54, namely a Type-C port and a Type-A port, and the third through hole 13 can be configured to be adapted to the shape of the Type-C port and the Type-A port.

[0036] Further as Figures 1-4 As shown in this embodiment of the present invention, the data plug 53 includes a data cable 531 and a transmission port 532. One end of the data cable 531 is electrically connected to the control board 52, and the other end of the data cable 531 is electrically connected to the transmission port 532. The base 1 has at least two reels 14 inside, into which the data cable 531 is wound up. The transmission port 532 extends from the second through hole 12. Specifically, the reels 14 are respectively installed inside the base 1 to store the data cable 531, enabling the data cable 531 to be stored. The specific structure of the reels 14 can be referred to in the embodiment described in patent CN215755657U, and will not be described further in this invention.

[0037] Further as Figures 1-4 As shown in this embodiment of the invention, a limiting block 533 is provided at one end of the data cable 531 near the transmission port 532. The size of the limiting block 533 is not smaller than the diameter of the second through hole 12. Specifically, the limiting block 533 can limit the length of the data cable 533 when it retracts, preventing the data plug 53 from completely retracting into the base 1, thus facilitating reuse. The limiting block 533 can be made of an elastic material, such as wear-resistant rubber. Figure 4 The second through hole 12 shown can be a stepped hole. The shape and size of the limiting block 533 are larger than the diameter of the hole near the inside of the base 1, which can make the limiting block 533 shrink into the stepped hole, making the overall appearance more aesthetically pleasing.

[0038] Further as Figures 1-4 As shown in the present invention, the transmission port 532 includes at least one of the following: a Type-C interface, a Lightning interface, a Micro-USB interface, and a MagSafe interface.

Specifically, the connection method between the mounting base 31 and the support rod 212 includes, but is not limited to, bonding, snap-fit ​​connection, etc., and can also be integrally molded, produced by injection molding or machining.

[0042] The working principle of this embodiment is as follows: A support frame 21 is set inside the lampshade 2 to support the lampshade 2. At the same time, the lampshade 2 is a detachable structure for easy replacement. During use, since the mounting base 31 and the connecting rod 3 are connected by a thread, the user can turn the mounting base 31 to adjust the height of the lampshade 2, thereby changing the light source. When the lampshade 2 is raised, the light source will gradually diffuse, and conversely, it will gradually converge inside the lampshade 2.

[0043] like Figure 3 As shown, in another embodiment of this utility model, the lampshade 2 is provided with 3 support bars inside to support the mounting base 31, and the outer axial surface of the mounting base 31 is provided with anti-slip grooves to facilitate the user's gripping and twisting.

[0044] Further as Figures 5-6 As shown in the embodiment of this utility model, the first through hole 11 is provided with an insulating sleeve 111, which is installed inside the first through hole 11, and the power plug 51 extends out from the insulating sleeve 111. The insulating sleeve 111 can prevent the data cable 531 from contacting the edge of the first through hole 11, protect the data cable 531 from wear and mechanical damage, and provide insulation. As shown in the figure, the rolled sleeve is in the shape of an "I" and is installed inside the first through hole 11.

[0045] In another embodiment of this utility model, the lampshade 2 is made of a semi-transparent material. Specifically, the material of the lampshade 2 includes, but is not limited to, frosted glass, milky white glass, or semi-transparent plastic, such as polypropylene (PP) or polystyrene (PS).
