Description

Technical Field

[0001] This utility model relates to the field of dining table technology, and in particular to a novel electric folding dining table. Background Technology

[0002] Dining tables are one of the most commonly used pieces of furniture in the home. In the current technology, the tabletop of most dining tables is fixed and unchanging. When there are many guests at home, the tabletop is too small to meet the needs of many people dining at the same time.

[0003] Folding dining tables currently on the market are adjusted and changed in size by manual folding, and then positioned by a positioning mechanism. This manual folding requires a lot of force to fold the tabletop, and the operation steps are numerous, cumbersome and complicated. In some cases, the tabletop may tilt and become unstable due to uneven force, or the positioning may be unstable and the tabletop may not be able to be fully extended or retracted, which greatly affects normal use and has a low degree of automation.

[0004] The prior art CN202220634179.6 provides an intelligent electric dining table that increases the practicality of the table while automatically changing the tabletop area, making it more convenient and faster to use.

[0005] However, this folding dining table primarily forms a quadrilateral table by folding down the extended sides of a round table. While this design saves space to some extent, its folding method is relatively simple and lacks flexibility. Furthermore, structural instability may occur during folding, affecting the user experience. Existing technologies already include various folding dining table designs, such as those using sliding rails and hinges to achieve extension and folding functions. However, these solutions often require complex mechanical structures to support the folding action, resulting in higher manufacturing costs. Additionally, these mechanical structures are prone to wear and tear during long-term use, affecting the table's lifespan.

[0006] Therefore, it is particularly important to develop a new type of electric folding dining table to improve its flexibility, ease of operation, and space utilization. Utility Model Content

[0054] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0055] like Figures 1 to 13 As shown, a new type of electric folding dining table includes a table frame 1 and an extension table board 2 fixedly mounted on the table frame 1. The table frame 1 is connected to a main table board 4 via a lifting and rotating device 3. The extension table board 2 is fixedly mounted on the outer ring of the main table board 4 and spliced ​​with the main table board 4 to expand the tabletop area of ​​the dining table.

[0056] The lifting and rotating device 3 drives the main tabletop 4 to rise and rotate above the extended tabletop 2 to reduce the tabletop area.

[0057] Specifically, the lifting and rotating device 3 includes a lifting component 5 and a rotating component 6. The lifting component 5 is installed on the table frame 1, and the rotating component 6 is installed on the upper side of the lifting component 5 and lifts and lowers synchronously with the lifting component 5. The main table board 4 is installed on the upper side of the rotating component 6 and rotates synchronously with the rotating component 6.

[0058] The lifting assembly 5 includes a first mounting plate 501, which is fixedly mounted on the table frame 1. A second mounting plate 503 is connected to the upper side of the first mounting plate 501 via a first telescopic rod 502. The second mounting plate 503 is located at the extended end of the first telescopic rod 502, and the rotating assembly 6 is mounted on the upper side of the second mounting plate 503. The first telescopic rod 502 is controlled by a first drive motor 504 to realize the vertical lifting of the main table 4.

[0059] Furthermore, the first telescopic rod 502 includes a main telescopic rod 505 located between the first mounting plate 501 and the second mounting plate 503, and the outer ring of the main telescopic rod 505 is provided with at least three linkage telescopic rods 506.

[0060] In this embodiment, the linkage telescopic rod 506 is a sleeve structure, in which a smaller diameter extension rod is sleeved into its fixed rod body. The main telescopic rod 505 is driven to move up and down by the first drive motor 504, which in turn drives the extension rod to move up and down within the fixed rod body.

[0061] The linkage telescopic rod 506 extends and retracts synchronously with the main telescopic rod 505, ensuring that the main tabletop 4 remains stable during the lifting and lowering process, reducing swaying and vibration, and improving the overall stability, load-bearing capacity and safety of the dining table. This ensures that the main tabletop remains stable during the lifting and lowering process, reducing swaying and vibration, making the dining table more reliable during use.

[0062] The first drive motor 504 is installed on the lower side of the main telescopic rod 505. The first drive motor 504 preferably adopts a dual-motor design, with a load-bearing capacity of up to 125kg. By increasing the torque and power of the motor, the lifting process is made more stable and powerful; or by optimizing the reduction ratio of the motor, its output torque can be increased without significantly increasing the motor power, thereby improving the load-bearing capacity.

[0063] Furthermore, the rotating assembly 6 includes a drive gear disk 601 mounted on a second mounting plate 503. The drive gear disk 601 is controlled by a second drive motor 602. The drive gear disk 601 meshes with a driven gear disk 603. A main table plate 4 is mounted on the upper side of the driven gear disk 603.

[0064] The main table 4 and the rotating component 6 rotate synchronously, and the main table 4, the rotating component 6 and the lifting component 5 lift synchronously.

[0065] The meshing transmission between the driving gear disk 601 and the driven gear disk 603 enables the rotation of the main table panel 4. The control of the second drive motor 602 makes the rotation process smoother and more controllable.

[0066] In this embodiment, an induction cooker panel 8 is installed on the upper side of the driven gear disk 603 via a second lifting assembly 7. The induction cooker panel 8 is installed in a height-adjustable manner at the center of the main table panel 4, so that the induction cooker panel 8 can be raised or lowered as needed, increasing the flexibility and functionality of the dining table.

[0067] Furthermore, the driven gear disk 603 is provided with at least three first connecting posts 604, and is fixedly connected to the main table panel 4 through the first connecting posts 604;

[0068] The second lifting assembly 7 includes a second lifting member 701, which is controlled by a third drive motor 702.

[0069] The first connecting column 604 is located on the outer ring of the second lifting component 701. The main table panel 4 has a through hole 401 in the center. The second lifting component 701 passes through the through hole 401 and can be lifted and connected to the induction cooker panel 8.

[0070] In this embodiment, as Figure 1 , Figure 2 , Figure 12 and Figure 13 As shown, its second lifting member 701 includes a lifting rod with a linear gear rack on its outer surface. A gear disk that meshes with the linear gear rack is provided on the third drive motor 702. The gear disk is driven to rotate by the third drive motor 702, which drives the linear gear rack to move up and down, thereby driving the lifting rod to move up and down.

[0071] Furthermore, the main table panel 4 includes a first table panel 402, a through hole 401 located at the center of the first table panel 402, the lower side of the first table panel 402 being connected to the first connecting post 604, and the first table panel 402 being located below the induction cooker panel 8 and having a diameter larger than the diameter of the induction cooker panel 8.

[0072] The outer edge of the first tabletop 402 is provided with an upward-facing second connecting post 403, and a second tabletop 404 is connected to it through the second connecting post 403. The second tabletop 404 is placed on the upper side of the first tabletop 402 through the second connecting post 403, and a recessed mounting groove 405 is formed between the inner ring of the second tabletop 404 and the upper side of the first tabletop 402. The induction cooker panel 8 is placed in the mounting groove 405 and is raised and lowered at the mounting groove 405 by the second lifting component 7.

[0073] like Figures 9 to 11 As shown, the second mounting plate 503 and the driven gear disk 603 are provided with a position sensor 9 for determining the rotation angle of the driven gear disk 603 and a limiting member 10 for limiting the rotation angle of the driven gear disk 603.

[0074] The position sensor 9 includes a sensor receiver 901 mounted on the second mounting plate 503 and a sensor generator 902 mounted on the driven gear disk 603;

[0075] The limiting member 10 includes an upper limit plate 1001 installed on the second mounting plate 503. There are two limiting plates 1001, both of which are located on the outer ring of the driven gear disk 603.

[0076] The driven gear disk 603 is provided with a synchronously rotating positioning plate 1002. The positioning plate 1002 moves between two limiting plates 1001 and is limited by the two limiting plates 1001. The induction generator 902 rotates at the same angle as the positioning plate 1002.

[0077] like Figures 1 to 13 As shown, in this embodiment, there are two extended tabletops 2, which are symmetrically arranged at both ends of the table frame 1, and the lifting and rotating device 3 is arranged in the middle of the table frame 1.

[0078] Better still, the table frame 1 includes table legs 101 and mounting frame 102. The extended tabletop 2 is symmetrically arranged at both ends of the mounting frame 102. The lifting and rotating device 3 is installed in the middle of the mounting frame 102. The main tabletop 4 is placed on the upper side of the mounting frame 102. The mounting frame 102 installs and supports the extended tabletop 2, the main tabletop 4 and the lifting and rotating device 3, thereby enhancing the load-bearing capacity and stability of the table frame 1.

[0079] When unfolded, the rotating tabletop 406 connected to the upper surface of the second tabletop 404 and the upper surface of the extended tabletop 2 are on the same horizontal line. The rotating tabletop 406 and the extended tabletop 2 are joined together to form a circular tabletop to expand the tabletop area.

[0080] When folding, the lifting and rotating device 3 first drives the main table board 4 to rise as a whole, and then rotates it 90 degrees through the rotating component 6 so that the rotating tabletop 406 is located on the upper side of the extension table board 2. At this time, the two ends of the rotating tabletop 406 completely cover the upper part of the extension table board 2. At this time, only the rotating tabletop 406 exists on the upper surface of the dining table to reduce the tabletop area. The rotating tabletop 406 is a quadrilateral tabletop with curved surfaces at both ends.

[0081] like Figure 1 As shown, a controller mounting plate 11 is also provided on the mounting frame 102, on which the control switch of the lifting and rotating device 3 can be installed for easier use.

[0082] In addition, the main tabletop 4 and the extension tabletop 2 can be spliced ​​together to form a circular tabletop, or other shapes of tabletops can be designed, such as oval or square, to meet the aesthetic needs of different users.

[0083] This invention uses three electric drive devices to achieve the lifting and rotation of the main table panel 4 and the lifting of the induction cooker panel 8, which can flexibly adjust the table area according to different dining needs.

[0084] When a smaller desktop area is needed, the main tabletop can be raised and rotated 90 degrees to place it on the two extended tabletops 2 on both sides, forming a compact quadrilateral desktop.

[0085] When it is necessary to expand the dining table area, the main tabletop 4 must first be rotated so that it is away from the top of the extension tabletop 2. In this example, the two limiting plates 1001 and the center of the driven gear disk 603 form an active space with a 90-degree angle. Therefore, the maximum rotation angle of the positioning plate 1002 is 90 degrees. When the lower surface of the main tabletop 4 is no longer overlapping with the top of the extension tabletop 2, the main tabletop 4 is lowered as a whole by the lifting component 5 until the main tabletop 4 and the extension tabletop 2 are on the same horizontal line and the outer side is spliced ​​with the extension tabletop 2 to form a larger circular tabletop.

[0086] The first drive motor 504 and the second drive motor 602 control the lifting and rotating of the main table 4, which greatly simplifies the operation process and reduces the difficulty of use. Users can extend and fold the table by simply pressing a button, which improves the convenience of users.

[0087] The main table panel 4 is also equipped with an induction cooker panel 8 in the middle. The induction cooker panel 8 is controlled by the third drive motor 702 and can be easily raised and lowered. It can be used to heat food and cook dishes, which greatly enhances the comprehensive functionality and practicality of the dining table. This high flexibility allows the dining table to adapt to a variety of dining scenarios and improves the user experience.

[0088] This invention, incorporating an automated mechanical device, significantly reduces the folded tabletop area by rotating the main tabletop 4 onto the extended tabletops 2 on both sides, thus improving space utilization. This allows the dining table to remain neat and aesthetically pleasing even when folded, further enhancing its ease of use. This invention demonstrates innovation in its electric drive device, multi-stage telescopic rod design, induction cooker panel lifting assembly, and multi-layer tabletop structure, not only improving operational convenience and the dining table's flexibility but also increasing its multifunctionality and stability.

[0089] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
