[0030] The utility model is further described below in conjunction with specific embodiments and drawings.

[0031] See Figure 1-12 As shown, a multifunctional desk lamp comprises a base 1 for being placed on a supporting surface, a lamp arm structure 2 which is mounted on the base 1 in a horizontally rotatable manner and can be rotated and bent at least once in a vertical plane to adjust the height, and a lamp head 3 which is mounted on the upper end of the lamp arm structure 2 and is used to emit illumination light. When in actual use, the base 1 is placed on a table top or other flat surface so that the lamp arm structure 2 and the lamp head 3 can stand stably on the table top or other flat surface. The height of the lamp head 3 can be adjusted by rotating and bending the lamp arm structure 2 so that the lamp head 3 is moved to the optimal position to achieve lighting. This is a conventional technical means in the field.

[0032] The lower end of the lamp arm structure 2 is provided with a second lamp arm 23, and a power PCB board 232 is arranged in the second lamp arm 23. The power PCB board 232 is provided with a power input interface 233 for power supply and a power output interface 234 for external electronic products. The power input interface 233 is a DC round hole interface, which is used for an external adapter to realize input power, thereby realizing power supply to the desk lamp; the lamp arm structure 2 is also provided with an auxiliary lighting module 4 for emitting light for auxiliary lighting. That is to say, the utility model not only realizes the lighting function through the lamp head 3, but also the lamp head 3 can adjust the height through the rotation and bending of the lamp arm structure 2, so that the lamp head 3 can be moved to the optimal position, so as to realize the lighting of the predetermined position to meet different usage requirements; because the lamp arm structure 2 can be rotated horizontally relative to the base 1, the lamp arm structure 2 can be rotated and bent in multiple vertical planes to adjust the lamp head 3 to any position, so as to further meet different lighting needs; the external electronic products can also be connected to the external charging cable through the power output interface 234 to charge the external electronic products, and play the function of a power bank, and the utility model is also provided with an auxiliary lighting module 4 for emitting light for auxiliary lighting, thereby increasing the lighting effect, so that the utility model has a large light illumination, can cover most of the visual area of ​​the desktop, the overall illumination is uniform and natural, and meets the customer's usage requirements, so that the utility model has a multi-functional effect and has a strong market competitiveness. In addition, since the lamp arm structure 2 can rotate horizontally relative to the base 1, the horizontal position of the second lamp arm 23 can be adjusted arbitrarily without moving the base, thereby adjusting the directions of the power input interface 233 and the power output interface 234, thereby meeting the different usage requirements of different users.

[0033] The lamp arm structure 2 is provided with a control circuit board 211 for controlling the operation of the lamp head 3 and a touch screen 212 electrically connected to the control circuit board 211. In specific use, the operation of the lamp head 3 can be controlled by the touch screen 212, and the operation data of the lamp head can also be displayed by the touch screen 212, which is extremely convenient to use. Moreover, since the first lamp arm 21 can rotate relative to the axial direction of the lamp head, the user can rotate the first lamp arm 21 by himself without rotating the lamp head 3 or adjusting the relative position of the lamp head 3, and then control and adjust the direction of the touch screen 212 to meet the operation requirements of different users, which is extremely convenient to use.

[0034] On this basis, the first lamp arm 21 is also provided with a human body sensor 210 for detecting or sensing a human body. The human body sensor 210 is electrically connected to the control circuit board 211. When the human body sensor 210 leaves the sensing area, the human body sensor 210 and the control circuit board 211 cooperate to control the lamp head 3 to turn off the light. In other words, under the premise that the user can control the lamp head 3 to work through the touch display screen 212, the human body sensor 210 can also be used to sense whether the human body is in the sensing area. When the human body is not in the sensing area, the human body sensor 210 and the control circuit board 211 cooperate to control the lamp head 3 to turn off the light, thereby achieving the effect of turning off the light when the person leaves. Among them, the human body sensor 210 is a conventional technical product. The technology of the human body sensor 210 sensing whether the human body is in the sensing area and then controlling the on and off of the lamp is a conventional technology, which will not be repeated here.

[0035] In addition, since the human body sensor 210 is set on the first lamp arm 21, the user can rotate the first lamp arm 21 by himself without rotating the lamp head 3 or adjusting the relative position of the lamp head 3, and then control and adjust the direction of the human body sensor 210 to meet the operating needs of different users, which is extremely convenient to use.

[0042] The upper and lower ends of the third rotating joint 26 are flat, the third lamp arm 25 is flat, the outer surface of the third lamp arm 25 is smoothly connected with the outer surface of the lower end of the third rotating joint 26, and the first screw and the second screw are blocked by the third lamp arm 25 or the lower end of the third rotating joint 26; when the third lamp arm 25 is rotated 90 degrees relative to the lower end of the third rotating joint 26, the first screw and the second screw are exposed and are not blocked by the third lamp arm 25 or the lower end of the third rotating joint 26, so as to facilitate the disassembly and assembly of the first screw and the second screw, and then facilitate the disassembly and assembly of the entire first axial rotating structure 27.

[0043] The base 1 includes a bottom plate 11, an upper cover 12 fixedly mounted on the bottom plate 11, a plurality of weight plates 13 fixed on a boss 111 sleeved on the bottom plate 11 and used to increase weight, a connecting seat 14 screwed fixed to the upper end of the upper cover 12, a nut seat 15 installed at the lower end of the connecting seat 14, a first plane bearing 16 arranged between the nut seat 15 and the connecting seat 14, a screw seat 17 installed at the upper end of the connecting seat 14 and screwed fixed to the nut seat 15 to cooperate with the nut seat 15 to clamp and fix the connecting seat 14, and a screw seat 17 arranged on the screw seat 1 7 and the second plane bearing 18 between the connecting seat 14, the screw seat 17 and the nut seat 15 can rotate relative to the connecting seat 14 through the first plane bearing 16 and the second plane bearing 18 when the connecting seat 14 is clamped, and the lower end of the lamp arm structure 2 is fixedly connected to the upper end of the screw seat 17, that is, the lamp arm structure 2 can not only be stably assembled with the base 1, but also can be rotated 360 degrees relative to the base 1 without being loosened, thereby meeting different usage requirements and being extremely convenient to use. The weight plate 13 is sleeved on the boss 111 of the bottom plate 11, and its assembly structure is stable. At the same time, the weight plate 13 increases the weight of the entire base 1, making the base bearing capacity better, and it is not easy to fall, thereby enabling the utility model to stand more stably on the desktop.
