Description
Technical Field
[0001] This utility model relates to the field of dining table technology, specifically to a retractable electric dining table. Background Technology
[0002] The dining table is one of the most commonly used pieces of furniture in a home.
[0003] In existing technologies, the tabletops of most dining tables are fixed and inconvenient. When there are many guests at home, the tabletop is often not enough due to its small area. At this time, it is necessary to use extra tables and chairs to expand the tabletop area, which is extremely inconvenient and results in a very poor consumer experience. Therefore, a retractable electric dining table is proposed to solve the above problems. Summary of the Invention
[0004] The purpose of this invention is to provide a retractable electric dining table to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable electric dining table, including a main tabletop,
[0006] The bottom of the main desktop is fixedly connected to a first electric telescopic rod and a second electric telescopic rod. The output ends of the first electric telescopic rod and the second electric telescopic rod are opposite. The output end of the first electric telescopic rod is fixedly connected to a first side telescopic desktop, and the output end of the second electric telescopic rod is fixedly connected to a second side telescopic desktop.
[0007] Furthermore, the first guide rails are provided on both the front and rear sides of the first telescopic desktop, and the first guide sliders are slidably connected on the first guide rails. The first guide sliders are fixedly connected to the front and rear side walls of the frame below the main desktop.
[0008] Furthermore, a third electric telescopic rod is fixedly connected to one end of the first telescopic desktop and the second telescopic desktop near the middle, one end of the third electric telescopic rod is fixedly connected to the third telescopic desktop, a fifth electric telescopic rod is fixedly connected to one end of the second telescopic desktop near the middle, and a fourth telescopic desktop is fixedly connected to one end of the fifth electric telescopic rod.
[0009] Furthermore, the third and fourth telescopic desktops are provided with second guide rails on both the front and rear sides, and second guide sliders are slidably connected on the second guide rails. The second guide sliders are respectively fixedly connected to the front and rear side walls of the frame below the first and second telescopic desktops.
[0010] Furthermore, a number of protective covers are fixedly connected to the bottom of the main desktop, and a fourth electric telescopic rod is installed inside the protective cover. The upper end of the fourth electric telescopic rod is fixedly connected to the bottom surface of the main desktop.
[0011] Furthermore, a clutter table is fixedly connected to the bottom end of the fourth electric telescopic rod, and multiple support legs are fixedly connected to the bottom end of the clutter table, with anti-slip pads fixedly connected to the bottom end of each support leg.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] By setting up a first, second, third, and fourth side tabletop, and using primary and secondary extension mechanisms on both sides of the main tabletop, the dining table area can be expanded in a stepped manner. Example: An initial 4-person table can be expanded to a 8-12 person table, adapting to different group needs, especially suitable for family gatherings or banquets. The first and second electric extension rods extend and retract synchronously in opposite directions, ensuring consistent expansion speed on both sides and avoiding jamming caused by uneven force. A fourth electric extension rod drives the main tabletop to rise and fall vertically, facilitating height adjustment. A first guide rail and slider, and a second guide rail and slider constrain the primary extension trajectory, preventing the first and second side tabletops from shifting. The second guide rail and slider ensure smooth extension of the secondary extension tabletop, preventing tilting. This dual-guide system ensures operational stability and safety; even fully loaded with tableware, the tabletop remains stable. A protective cover completely encloses the fourth electric extension rod, preventing food debris or liquid from entering the mechanical parts and extending its lifespan. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4This utility model provides a technical solution for a retractable electric dining table: a retractable electric dining table includes a main tabletop 1, with a first electric telescopic rod 2 and a second electric telescopic rod 3 fixedly connected to the bottom end of the main tabletop 1. The output ends of the first electric telescopic rod 2 and the second electric telescopic rod 3 are opposite. The output end of the first electric telescopic rod 2 is fixedly connected to a first side telescopic tabletop 4. By setting the first side tabletop, the second side tabletop, the third side tabletop, and the fourth side tabletop, the table area can be expanded in a step-like manner through the first-level telescopic (first side tabletop and second side tabletop) and the second-level telescopic (third side tabletop and fourth side tabletop) on both sides of the main tabletop 1. Example: The initial 4-person table can be expanded to 8-12 person tables to accommodate different number of people, especially suitable for family gatherings or banquets. The first electric telescopic rod 2 and the second electric telescopic rod 3 extend and retract synchronously in opposite directions to ensure that the extension speed of the tabletops on both sides is consistent and to avoid jamming caused by uneven force. The output end of the second electric telescopic rod 3 is fixedly connected to the second side telescopic tabletop 16. The front and rear sides of the first side telescopic tabletop 4 are provided with first guide rails 5. By setting the first guide rail 5, slider, second guide rail 9 and slider, the first guide rail 5 and slider constrain the first telescopic trajectory to prevent the first side tabletop from shifting to the second side tabletop. The second guide rail 9 and slider ensure that the second telescopic tabletop extends smoothly and avoids tilting. The dual guide system ensures stable operation and safety. Even when fully loaded with tableware, the tabletop does not shake. The first guide rail 5 is slidably connected to the first guide slider 6, which is fixedly connected to the front and rear side walls of the frame below the main tabletop 1.
[0024] A third electric telescopic rod 7 is fixedly connected to one end of the first telescopic tabletop 4 and the second telescopic tabletop 16 near the middle. One end of the third electric telescopic rod 7 is fixedly connected to a third telescopic tabletop 8. A fifth electric telescopic rod 17 is fixedly connected to one end of the second telescopic tabletop 16 near the middle. One end of the fifth electric telescopic rod 17 is fixedly connected to a fourth telescopic tabletop 18. Second guide rails 9 are provided on both the front and rear sides of the third and fourth telescopic tabletops 8 and 18. Second guide sliders 10 are slidably connected to the second guide rails 9. The second guide sliders 10 are fixedly connected to the front and rear side walls of the frame below the first and second telescopic tabletops 4 and 16, respectively. The main tabletop 1... Several protective covers 11 are fixedly connected to the bottom. By setting the protective covers 11, the protective covers 11 completely cover the fourth electric telescopic rod 12, preventing food scraps or liquids from entering the mechanical parts and extending the service life. The fourth electric telescopic rod 12 is set inside the protective cover 11. By setting the fourth electric telescopic rod 12 and the miscellaneous table 13, the fourth electric telescopic rod 12 drives the main table 1 to rise and fall vertically, which is convenient for adjusting the height of the dining table. The upper end of the fourth electric telescopic rod 12 is fixedly connected to the bottom surface of the main table 1, and the bottom end of the fourth electric telescopic rod 12 is fixedly connected to the miscellaneous table 13. The bottom end of the miscellaneous table 13 is fixedly connected to multiple support legs 14, and the bottom end of the support legs 14 is fixedly connected to anti-slip pads 15.
[0025] The first electric telescopic rod 2, the second electric telescopic rod 3, the third electric telescopic rod 7, the fifth electric telescopic rod 17, and the fourth electric telescopic rod 12 are all electric linear actuators, each integrating a motor and a lead screw transmission mechanism. All electric telescopic rods are electrically connected to an external power source and a central controller. The central controller can precisely control the extension and retraction stroke and speed of each electric telescopic rod according to user instructions. To ensure the synchronous expansion and contraction of the two telescopic tabletops (4, 16) and the secondary tabletops (8, 18), the system adopts multi-axis synchronous control technology, combined with displacement sensors to provide real-time feedback on the stroke of each telescopic rod. The central controller performs closed-loop control, thereby ensuring smooth and uniform extension and contraction of the tabletops, avoiding jamming and tilting. The first guide rail 5 and the second guide rail 9 are linear guide rails, and the first guide slider 6 and the second guide slider 10 are sliding seats that match the guide rails. This precision guide rail and slider structure ensures that each level of telescopic tabletop can extend and contract smoothly and without shaking along a preset trajectory when moving horizontally, providing high-precision guidance and improving operational stability and safety.
[0026] When in use, the desktop area expands (width extends):
[0027] First-stage expansion (both sides of the main desktop): When the desktop needs to be expanded, the first electric telescopic rod 2 and the second electric telescopic rod 3 are activated simultaneously and extend outwards. Since their output ends face opposite directions (one to the left, one to the right), they respectively push the first telescopic desktop 4 and the second telescopic desktop 16 horizontally outwards, away from the center of the main desktop 1; Guiding guarantee: The first guide rail 5 on the first telescopic desktop 4 cooperates with the first guide slider 6 fixed to the main desktop frame to ensure that the first telescopic desktop 4 can only slide smoothly along a straight line and will not tilt. The guiding mechanism of the second telescopic desktop 16 is similar (although not explicitly stated, the structure is symmetrical and the principle is the same).
[0028] Second-stage extension (outside the side tabletop): After or immediately following the first-stage extension, the third electric telescopic rod 7 and the fifth electric telescopic rod 17 are activated and extended outward. The third electric telescopic rod 7 pushes the third side telescopic tabletop 8 to move horizontally outward from the end of the first side telescopic tabletop 4, and the fifth electric telescopic rod 17 pushes the fourth side telescopic tabletop 18 to move horizontally outward from the end of the second side telescopic tabletop 16.
[0029] Secondary guidance is ensured by the cooperation of the second guide rail 9 on the third telescopic tabletop 8 and the second guide slider 10 fixed on the frame of the first telescopic tabletop 4, which ensures that the third telescopic tabletop 8 slides smoothly and linearly. Similarly, the fourth telescopic tabletop 18 and the second telescopic tabletop 16 also have the same guiding structure.
[0030] Effect: Through the coordinated operation of these two telescopic mechanisms, the effective usable width of the dining table expands from the main tabletop 1 to include all the side telescopic tabletops (4, 16, 8, 18), significantly increasing the tabletop area;
[0031] The fourth electric telescopic rod 12 extends → pushing the main tabletop 1 and the side tabletops up to facilitate height adjustment.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
