[0028] It should be noted that the computer desk with display lifting function further comprises a power drive module for providing power for the lifting of the computer desk, and the power drive module is specifically a 24V DC power module. The power drive module meets the requirements of weak current in engineering practice and satisfies the human body safety voltage requirement, so that the risk of direct contact is extremely low. Therefore, the computer desk using the 24V DC power source has high use safety.

[0029] In addition, the number of displays 20 in the utility model is not limited to two, and can be set to one, three, four, etc. The number is not limited too much.

[0030] Referring to Figure 2 As a preferred technical solution of the embodiment, the support 10 comprises a main frame and a desktop panel 120 arranged on the top of the main frame. The main frame comprises two side frames 111 and a connecting frame 112 arranged between the two side frames. In this way, the main frame structure of the support is formed by the connecting frame and the side frames, and the main frame structure is used to place the display 20 and other components.

[0031] Further, the cabinet 30 is a rectangular box structure arranged inside the support 10. When the display is lowered by the action of the lifting mechanism, the display can be sunk into the rectangular box structure, thereby achieving storage of the display. In addition, the computer desk further comprises a host computer 50 arranged on the side wall of the cabinet 30, thereby forming a complete computer structure.

[0032] Referring to Figure 3 , Figure 4 In some embodiments, the driving source comprises a motor 411 arranged inside the cabinet 30 and a transmission rod 412 arranged at the output end of the motor. It should be noted that the transmission rod is a hexagonal transmission rod, and the transmission rod is connected to the screw rod assembly through a shaft coupling. In this way, after the driving source transmits power to the transmission rod, the screw rod assembly can be driven, thereby driving the lifting assembly to realize the lifting function.

[0033] Further, the screw rod assembly comprises a screw rod 421, a lifting seat 422, and a lifting cross beam 423. The screw rod 421 is arranged vertically along the inner side of the cabinet 30 and is driven to rotate by the transmission rod 412. The lifting seat 422 is threadedly connected to the screw rod, and the lifting cross beam 423 is fixedly arranged on the lifting seat. The display 20 is fixedly connected to the lifting cross beam. In use, the screw rod is driven to rotate by the transmission rod, thereby driving the lifting seat and the lifting cross beam to move along the vertical direction of the cabinet. Since the display is fixedly connected to the lifting cross beam, the lifting of the display can be realized.

[0034] Further, in order to improve the stability of the display during the lifting and moving process, the screw rod assembly further comprises a guide rail 424 and a sliding block 425. The guide rail 424 is arranged on the inner side wall of the cabinet 30 parallel to the screw rod 421. The sliding block 425 is matched with the guide rail and can slide along the guide rail. The sliding block is fixedly connected to the lifting cross beam 423. In this way, when the screw rod assembly drives the lifting cross beam to move, the sliding block can be simultaneously driven to move along the guide rail. The linear guiding effect of the guide rail can improve the stability of the lifting and moving of the lifting cross beam and the display thereon.

[0035] In some embodiments, the computer desk with the display lifting function further comprises a stroke limiting assembly. The stroke limiting assembly comprises a lower limit switch 610 and an upper limit switch 620. The lower limit switch 610 is arranged on the bottom wall of the cabinet 30, and the upper limit switch 620 is arranged on the side wall of the desktop panel 120. In use, when the lifting assembly drives the lifting cross beam and the display to descend, the lifting cross beam can send a signal to the driving source when it contacts the lower limit switch, at which time the lifting cross beam stops descending. When the lifting cross beam rises to contact the upper limit switch, it can send a signal to the driving source, at which time the lifting cross beam stops rising. In this way, the lower limit switch and the upper limit switch can limit the upper and lower stroke displacement of the lifting cross beam, thereby preventing the lifting cross beam and the display thereon from being excessively displaced.

[0036] Referring to Figure 2Further, the desktop panel 120 is provided with a through hole 121, and the display 20 is provided with a rising plate 210 matched with the through hole 121, so that the rising plate 210 moves along the through hole 121 when the display 20 moves up and down along the lifting cross beam.

[0037] With reference to Figure 5 As a preferred technical scheme of the embodiment, the through hole 121 is rotatably connected with a flip cover 70, the flip cover 70 comprises a rotating end and a flipping end, the rotating end of the flip cover 70 is rotatably connected with the inner wall of the through hole 121 through a hinge, and the flipping end of the flip cover 70 is used to be pulled to realize the flipping function. In order to facilitate the driving of the flip cover, a pulling piece is fixedly arranged on the sidewall of the flip cover. Further, the computer desk with the display lifting function further comprises a flipping mechanism for driving the flip cover to open and close, the flipping mechanism comprises a wire wheel set and a pulling rope 820, the wire wheel set is arranged on the inner wall of the cabinet 30, the pulling rope 820 is a steel wire rope in the embodiment, and the pulling rope 820 is arranged between the wire wheel set and the flipping end of the flip cover 70. The pulling rope 820 is used to pull the flip cover to open and close.

[0038] Further, the wire wheel set comprises a plurality of wire wheels 810 rotatably arranged along the two opposite sidewalls of the cabinet 30, one end of the pulling rope 820 is fixedly connected with the flipping end of the flip cover 70, and the other end of the pulling rope 820 passes through the wire wheel 810 on one sidewall of the cabinet and extends to be wound on the wire wheel 810 on the other sidewall of the cabinet. In the embodiment, the number of the wire wheels 810 is three, two of which are rotatably arranged on one sidewall of the cabinet, and the other is rotatably arranged on the other sidewall of the cabinet. The three wire wheels form an L-shaped structure arrangement. One end of the pulling rope starts from the pulling piece, passes through the two wire wheels on one sidewall of the cabinet and extends to be wound on the wire wheel on the other sidewall of the cabinet. When the flip cover is opened by pressing the lifting key, the display is lifted to the desktop and stops when the lifting cross beam contacts the upper limit switch. When the display is lowered by pressing the lowering key, the lifting cross beam is lowered to the bottom of the cabinet and pulls the pulling rope to drive the flip cover to close, and the lifting cross beam automatically stops when contacting the lower limit switch.

[0039] When the lifting key is pressed, the driving source in the lifting mechanism drives the screw rod assembly to work, the screw rod assembly in turn drives the lifting assembly to rise, and since the lifting assembly is connected with the display 20, the display 20 can be synchronously lifted. Similarly, when the lowering key is pressed, the lifting assembly can be lowered under the action of the driving source and the screw rod assembly, and the display 20 can be lowered. The embodiment realizes the lifting function by using the screw rod transmission mode, has the advantages of high transmission efficiency, and can realize the stable movement of the lifting cross beam by combining the high-precision and high-strength linear guide rail, so that the defects of low efficiency and high failure rate of the traditional lifting rack transmission can be avoided.
