[0036] Please see Figures 1 to 2A multifunctional desktop structure includes a movable fixed frame 1, a movable component 2, a flip fixed frame 3, a flip component 4, and a tabletop 5. The tabletop 5 can move along the width of the desktop and provides a flipping function to adapt to different usage environments and needs.

[0037] Please see Figures 3 to 4 The movable fixed frame 1 is installed on the table legs and provides support for the entire tabletop structure, laying the foundation for the subsequent movement and flipping of the tabletop 5. The movable component 2 is used to realize the translation of the tabletop 5 in the width direction of the tabletop. The movable component 2 includes a movable drive mechanism 21, a first lead screw 22, and a movable rod 23. Both the drive mechanism 21 and the first lead screw 22 are mounted on the movable fixed frame 1. The first lead screw 22 is connected to the output end of the movable drive mechanism 21, allowing the movable drive mechanism 21 to drive the first lead screw 22 to rotate. The movable rod 23 is movably mounted on the movable fixed frame 1 and connected to the first lead screw 22. When the first lead screw 22 rotates, it drives the movable rod 23 to extend or retract in the width direction of the tabletop. The flipping fixed frame 3 is connected to the movable rod 23 and moves synchronously with it. The flipping component 4 is mounted on the flipping fixed frame 3 and moves synchronously with it. The flipping assembly 4 is used to flip the tabletop 5. The flipping assembly 4 includes a flipping drive mechanism 4121, a second lead screw 42, a threaded sleeve 43, and a flipping arm 44. Both the flipping drive mechanism 4121 and the second lead screw 42 are mounted on the flipping fixing frame 3. The second lead screw 42 is connected to the output end of the flipping drive mechanism 4121, which drives the second lead screw 42 to rotate. The threaded sleeve 43 is slidably fitted onto the second lead screw 42, and when the second lead screw 42 rotates, it drives the threaded sleeve 43 to slide along the length of the second lead screw 42. The lower end of the flipping arm 44 is mounted on the threaded sleeve 43, and the upper end is hinged to the lower end face of the tabletop 5. One end of the tabletop 5 is hinged to the front end of the flipping fixing frame 3, specifically through a hinge or similar structure.

[0038] The moving drive mechanism 21 drives the first lead screw 22 to rotate, which in turn causes the movable rod 23 to extend. The extension of the movable rod 23 causes the flipping fixed frame 3, the flipping assembly 4, and the tabletop 5 to move synchronously. The flipping drive mechanism 4121 drives the second lead screw 42 to rotate, which in turn causes the screw sleeve 43 to slide. The sliding of the screw sleeve 43 causes the flipping arm 44 to move, and the movement of the flipping arm 44 causes the tabletop 5 to flip upward relative to the flipping fixed frame 3.

[0039] Existing desktop structures of this type integrate the translation and flipping mechanisms within the same frame, resulting in a complex structure and inconvenient assembly and maintenance. This technical solution, however, uses a movable fixing frame 1 and a flip fixing frame 3 to separately mount the movable component 2 and the flipping component 4, achieving relative independence between the translation and flipping mechanisms and resulting in a simpler overall structure. The flip fixing frame 3 and flipping component 4 can be assembled independently before connecting to the movable component 2, and the movable component 2 can also be independently assembled to the movable fixing frame 1. Therefore, assembly is quick and convenient, and subsequent maintenance is also easier.

[0040] Please see Figure 1 and Figure 7 The multi-functional desktop structure also includes a first protective cover plate 6, which is installed above the flip-fixed frame 3 and below the desktop 5. The flip-fixed frame 3 is located directly above the flip assembly 4 to cover it. Since the flip arm 44 is connected to the lower end face of the desktop 5, a clearance groove 61 is provided on the first protective cover plate 6. The flip arm 44 can extend through the clearance groove 61 to the top of the first protective cover plate 6 to connect with the lower end face of the desktop 5. The clearance groove 61 has a certain length so that the movement of the flip arm 44 is not restricted during the flipping of the desktop 5. By setting the first protective cover plate 6, the flip assembly 4, a transmission mechanism, can be covered to prevent the parts from causing injury to the user during movement, and also to prevent items on the desktop from falling onto the flip assembly 4 and affecting its normal operation.

[0041] Please see Figure 1 The multi-functional desktop structure also includes a second protective cover 7, which is installed on the movable fixed frame 1 and located above the movable drive mechanism 21 to cover it. By setting the second protective cover 7, the movable drive mechanism 21 can be covered to prevent it from causing injury to the user during operation, and also to prevent items on the desktop from falling and affecting the normal operation of the movable drive mechanism 21.

[0042] Please see Figure 2The movable fixing frame 1 includes a first horizontal bar 11 and two first vertical bars 12. One end of each of the two first vertical bars 12 is connected to both ends of the first horizontal bar 11. The two first vertical bars 12 are of the same length, parallel to each other, and located on the same side of the first horizontal bar 11. The first vertical bars 12 are hollow tubular structures, and their specific shape can be a square tube, a semi-circular tube with an outer arc, or even a round tube. Each first vertical bar 12 is provided with a first lead screw 22, so there are two first lead screws 22; the two first lead screws 22 are of the same length and parallel to each other. There are also two movable rods 23, with one first lead screw 22 corresponding to one movable rod 23. Both movable rods 23 are simultaneously connected to the flip fixing frame 3. The moving drive mechanism 21 includes a first drive motor 211 and a first transmission shaft 212. The first drive motor 211 is mounted on the moving fixed frame 1, and its output end is connected to the first transmission shaft 212, allowing the first drive motor 211 to drive the first transmission shaft 212 to rotate. Both ends of the first transmission shaft 212 are connected to two first lead screws 22 via gearboxes, and the first transmission shaft 212 is perpendicular to the first lead screws 22. The first drive motor 211 drives the first transmission shaft 212 to rotate, which in turn drives the two first lead screws 22 to rotate. The rotation of the first lead screws 22 causes the movable rod 23 to extend or retract, thereby controlling the movement of the flipping fixed frame 3, the flipping assembly 4, and the tabletop 5. This arrangement of the moving fixed frame 1 facilitates the placement of the first lead screw 22 and the movable rod 23, and the first vertical rod 12 can accommodate the first lead screw 22, preventing it from being exposed. The first drive motor 211 synchronously drives the two first lead screws 22 to rotate, thereby enabling the two moving rods 23 to synchronously drive the table 5 to move, ensuring the synchronization of the movement and improving the smoothness and stability of the table 5 movement.

[0043] Specifically, please refer to Figure 2 The flip-fixing frame 3 is located between the two first vertical bars 12. By placing the flip-fixing frame 3 between the two first vertical bars 12, the compactness of the structure can be improved and the flat area of ​​the overall structure can be reduced.

[0044] Please see Figure 3 The first drive shaft 212 includes a left shaft 2121, a right shaft 2122, and a coupling 2123. The left shaft 2121 and the right shaft 2122 are detachably connected by the coupling 2123. By setting the coupling 2123 to achieve the detachable connection of the left shaft 2121 and the right shaft 2122, the left shaft 2121 and the right shaft 2122 can be disassembled and placed separately during packaging and transportation. When the product is assembled, the left shaft 2121 and the right shaft 2122 are connected again by the coupling 2123 to form the first drive shaft 212, which is convenient for users to assemble, reduces the packaging length, and facilitates transportation.

[0045] Please see Figures 4 to 5The flipping fixing frame 3 includes a second horizontal bar 31, a third horizontal bar 32, and two second vertical bars 33. These components are connected at their ends to form a rectangular frame. The flipping assembly 4 is located within the area enclosed by the flipping fixing frame 3. The second horizontal bar 31 and the third horizontal bar 32 are parallel and spaced apart. The two second vertical bars 33 are also parallel and spaced apart. Both second vertical bars 33 are of the same length, and one end of each is fixedly connected to both ends of the third horizontal bar 32. The length of the second horizontal bar 31 is greater than the length of the third horizontal bar 32. After the other ends of the two second vertical bars 33 are connected to the second horizontal bar 31, both ends of the second horizontal bar 31 protrude outwards relative to the second vertical bars 33. The protruding portions of the second horizontal bar 31 are connected to the ends of the two movable rods 23. The flipping fixing frame 3 has a simple structure, allowing the entire flipping mechanism to form a compact and relatively independent mechanism.

[0046] Please see Figure 5 The flip-fixed frame 3 also includes a mounting plate 34, one end of which is connected to the second crossbar 31 and the other end to the third crossbar 32. A sliding groove 341 extending along the length of the mounting plate 34 is provided, the length of which is consistent with the length of the second lead screw 42. The lower end of the threaded sleeve 43 is located within the sliding groove 341 and can slide within it along its length. By providing the mounting plate 34, the stability of the structure can be improved, ensuring that the threaded sleeve 43 can slide smoothly along the second lead screw 42. The sliding groove 341 on the mounting plate 34 also limits the maximum stroke of the threaded sleeve 43, preventing the tabletop 5 from over-flipping.

[0047] Please see Figure 4 and Figure 6The flipping fixing frame 3 is equipped with two second lead screws 42, which are parallel to each other and spaced apart. The two ends of each second lead screw 42 are connected to the second crossbar 31 and the third crossbar 32, respectively. Each second lead screw 42 is fitted with a threaded sleeve 43, and each threaded sleeve 43 is equipped with a flipping arm 44; therefore, there are two threaded sleeves 43 and two flipping arms 44. The flipping drive mechanism 4121 includes a second drive motor 411 and a second rotating shaft. The second drive motor 411 is mounted on the flipping fixing frame 3, specifically on the third crossbar 32. The output end of the second drive motor 411 is connected to the second transmission shaft 412, which can drive the second transmission shaft 412 to rotate. The two ends of the second transmission shaft 412 are respectively connected to the two second lead screws 42 via gearboxes, and the second transmission shaft 412 is perpendicular to the second lead screws 42. The second drive motor 411 drives the second transmission shaft 412 to rotate. When the second transmission shaft 412 rotates, it causes the threaded sleeve 43 to slide, and the flipping arm 44 moves with the threaded sleeve 43. Since the upper end of the flipping arm 44 is hinged to the lower end face of the table 5, the flipping arm 44 can push the table 5 to flip upward around the hinge point between the table 5 and the flipping fixing frame 3 when it moves. By synchronously driving the two second lead screws 42 to rotate through the second drive motor 411 and the second transmission shaft 412, the two threaded sleeves 43 slide synchronously. Finally, the two flipping arms 44 drive the table 5 to flip simultaneously, ensuring the synchronicity of the flipping and improving the smoothness and stability of the table 5 flipping.

[0048] Please see Figures 8 to 9 A height-adjustable desk includes height-adjustable legs 10 and a multi-functional desktop structure. A movable fixed frame 1 is installed on the upper end of the height-adjustable legs 10, and the height-adjustable legs 10 can be controlled to raise and lower the multi-functional desktop structure. The entire height-adjustable desk not only has desktop lifting function, but also tabletop 5 movement and tabletop 5 flipping function.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
