Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a tabletop assembly suitable for desks, computer desks, workbenches, etc., which can switch between desktop extension and storage functions, as well as a table including the tabletop assembly. Background Technology

[0002] In modern furniture, especially in applications such as office desks and study desks, structures with movable additional panels are often used to enhance desktop functionality and flexibility, such as flip-up extension panels or height-adjustable support platforms. These additional functional panels typically utilize mechanisms such as linkages, hinges, and pivots to change their position, expanding the desktop area or creating elevated support areas to meet diverse user needs for writing, reading, or device support.

[0003] However, the following problems are common in existing technologies:

[0004] 1. In the existing tabletop assembly, during the process of switching the functional panel from a low position to a high position, the rotation trajectory of the connecting rod or support structure often comes into contact with or collides with the edge of the tabletop. This is especially true when the panel structure is thick or the rotation path is close to the tabletop, which can easily cause movement jamming or structural interference, affecting the smoothness of use and the lifespan of the structure.

[0005] 2. To avoid collisions, some solutions attempt to place the connecting rods away from the tabletop, but this sacrifices the overall compactness and aesthetics, hinders the integrated design of the product, and makes it difficult to meet the requirements of modern homes for lightweight structures and simple appearances. Utility Model Content

[0006] The present invention aims to provide a tabletop assembly and a table to solve the problem in the prior art that the functional panel is prone to interference with the edge of the tabletop during the process of switching to the high position, which affects the smoothness of movement.

[0007] The tabletop assembly provided by this utility model includes:

[0008] Tabletop;

[0009] Functional panel;

[0010] A connecting mechanism connects the tabletop and the functional panel, and is configured to be movable so that the functional panel can switch between a first state and a second state;

[0011] In the first state, the functional panel is adjacent to the tabletop, and the upper surface of the functional panel is basically flush with the upper surface of the tabletop, which is used to expand the desktop area; in the second state, the functional panel is located in the area above the opposite edge of the tabletop, which is used to support items.

[0012] Furthermore, the connecting mechanism includes at least one first movable link with a clearance structure, the clearance structure being configured such that when the functional panel is in the second state, the edge portion of the tabletop is located within the gap area formed by the clearance structure, and the connecting mechanism avoids the tabletop during the switching process of the functional panel between the first and second states.

[0013] Preferably, a gap is provided between the functional panel and the adjacent edges of the tabletop in the first state.

[0014] Preferably, the connecting mechanism further includes at least one second movable link;

[0015] The first end of the first movable link and the first end of the second movable link are both rotatably connected to the first structural part connected to the tabletop, and the second end of the first movable link and the second end of the second movable link are both rotatably connected to the second structural part connected to the functional panel.

[0016] The first movable link and the second movable link are combined in a one-to-one correspondence, and together with the first structural part and the second structural part, they form at least one parallel four-bar linkage mechanism, which is used to ensure that the functional panel remains parallel to the tabletop when switching between the first state and the second state.

[0017] Preferably, the first movable link has a curved structure to form a clearance space for accommodating the edge of the tabletop when the functional panel is in the second state.

[0018] Preferably, the first movable link has a turning portion, which is used to provide a limiting or supporting function for the rotational connection area between the second movable link and the second structural part in the same parallel four-bar linkage when the functional plate is in the second state.

[0024] Preferably, the tabletop assembly further includes a cable tray, which is fixedly disposed at the rear of the tabletop. The cable tray is located in the lower space area corresponding to the switching process between the first and second states of the functional board, so as to accommodate cables led out from electronic devices on the functional board.

[0025] The table provided by this utility model is characterized by including the aforementioned tabletop assembly.

[0026] Compared with the prior art, the present invention has the following significant advantages:

[0027] This invention, by incorporating a first movable link with a clearance structure in the connecting mechanism, allows the functional panel to effectively avoid the edge of the tabletop during state switching, thus preventing the jamming problems caused by spatial overlap or structural interference in existing technologies. Simultaneously, the structural design of the first movable link itself balances the motion path and structural layout, ensuring the overall mechanism maintains a compact arrangement while guaranteeing motion functionality. This solves the problem of loose structure or excessive installation space occupied by traditional tabletop components due to limited link paths, thereby improving overall adaptability and practicality.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only for explaining this utility model and are not intended to limit it.

[0040] This utility model provides a tabletop assembly and a table including the tabletop assembly, aiming to solve the technical problems of limited desktop space and single function in the existing tabletop, especially the problem of interference with the edge of the tabletop during the switching of functional panels.

[0041] like Figures 1 to 10 As shown, the tabletop assembly in this embodiment mainly includes a tabletop 10, a functional board 20, and a connecting mechanism.

[0042] The tabletop 10 is part of the main tabletop; the functional panel 20 is an additional panel that can switch between two states, including a first state and a second state.

[0043] When the function board 20 is in the first state, the function board 20 is adjacent to the tabletop 10, and its upper surface is basically flush with the tabletop 10, which is used to extend the desktop.

[0044] When the functional panel 20 is in the second state, the functional panel 20 is located in the area above the edge of the tabletop 10 and is used for high-level support.

[0045] To achieve the above switching, the connecting mechanism connects the table 10 and the functional plate 20 and is constructed as a movable structure. In particular, it is provided with an avoidance structure to prevent the functional plate 20 from interfering with the edge of the table 10 during the process of switching from the first state to the second state and from the second state to the first state, thus ensuring a compact structure and smooth movement.

[0046] The avoidance structure comprises at least one first movable link 41, which has a curved structure, such as an L-shaped bend or a U-shaped bend. In one embodiment, the first movable link 41 is L-shaped, and the space between the two arms of the L-shaped first movable link 41 is an avoidance space or gap area; in another embodiment, the first movable link 41 is U-shaped (e.g., Figure 8 The U-shaped opening formed by the first movable link 41 is the clearance space 411 or gap area, which can accommodate the edge of the tabletop 10 when the functional plate 20 is raised, thus achieving the clearance function. This design effectively solves the problems of jamming and collision that may occur during the movement of conventional direct connection structures, and improves the compactness and smoothness of the mechanism.

[0047] Furthermore, the connecting mechanism preferably includes two parallel four-bar linkages, respectively disposed at the left and right ends of the functional plate 20, to enhance its stability and load-bearing balance during movement. Each parallel four-bar linkage is composed of the following components:

[0048] First moving link 41;

[0049] Second movable link 42;

[0050] The first structural part connected to the tabletop 10 (including the first connector 60 and the fixing rod 43);

[0051] The second structural part (including the output rod 44) ​​is connected to the functional panel 20.

[0052] The first movable link 41 and the second movable link 42 are respectively rotatably connected at their first ends to the fixed link 43 and at their second ends to the output link 44. Since the lines connecting the two ends of the first movable link 41 to the two connection points of the fixed link 43 and the output link 44 are parallel to the lines connecting the two ends of the second movable link 42 to the two connection points of the fixed link 43 and the output link 44, and the fixed link 43 and the output link 44 are parallel, a stable parallel four-bar linkage mechanism can be formed. During the switching process, the functional board 20 remains substantially parallel to the tabletop 10, ensuring the reliability and safety of desktop expansion and high-level load-bearing.

[0053] like Figure 4 , Figure 5As shown, the two sets of parallel four-bar linkages can be connected by synchronous linkage 80 to achieve synchronous rotation of the movable linkages on the left and right sides, avoiding problems such as offset, tilting or inconsistent angles.

[0054] The first movable link 41 not only has a curved structure, but may also have a turning part 412. When the functional plate 20 is in the second state, the turning part 412 can provide a limit or support for the rotational connection area between the second movable link 42 and the output rod 44 in the same four-bar linkage, further improving the stability after the movement is in place and preventing sagging or over-positioning.

[0055] The second movable link 42 can be either curved or non-curved.

[0056] Preferably, the second movable link 42 and the first movable link 41 can have the same geometric structure to reduce manufacturing and assembly complexity and improve the versatility of parts.

[0057] In terms of the fixed structure, the first connecting member 60 in the first structural part is fixed to the rear of the tabletop 10 and extends rearward, supporting the fixed rod 43 as the first rotating base of the movable link. The fixed rod 43 is connected to the side of the first connecting member 60 near the outer side of the tabletop 10. The output rod 44 in the second structural part is fixedly connected to the functional plate 20 and extends along the width direction, serving as the second rotating base of the movable link. The first movable link 41 and the second movable link 42 are rotatably connected at the aforementioned ends, jointly achieving a stable parallel motion path.

[0058] like Figure 9 As shown, to facilitate the organization of cables extending from electronic devices on the function board 20 or the desktop, the tabletop assembly further includes a cable management channel 91 located behind the tabletop 10. This cable management channel 91 is situated in the lower space area covered by the function board 20 during the switching between the first and second states, effectively storing cables, preventing clutter, and improving aesthetics and safety.

[0059] The cable tray 91 is preferably fixed between the two second connectors 70, using the rigid support it provides to enhance installation stability. The second connectors 70 are located between the two first connectors 60 and are fixed by welding, screws, or clips, which not only improves the overall structural strength of the tabletop assembly but also serves as a mounting base for accessory modules.

[0060] like Figure 10 As shown, the tabletop assembly can also be equipped with optional modules such as a bracket 92, a storage basket 93, and an earphone hanger 94. These modules are installed on the front edge of the functional panel 20 via snap-fit ​​mechanisms, facilitating quick assembly and disassembly and flexible configuration. The bracket 92 can be configured in two sizes to support different electronic devices, the storage basket 93 is used to store stationery or office supplies, and the earphone hanger 94 is convenient for storing earphones.

[0061] This utility model also provides a table, including the aforementioned tabletop assembly. This table integrates conventional table legs and a support structure, providing desktop extension, high load-bearing capacity, and multi-functional storage capabilities while retaining the basic functions of a traditional table. It is suitable for various application scenarios such as office, study, and home use, and possesses excellent practicality and market prospects.
