Detailed Implementation

[0033] 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.

[0034] like Figures 1 to 7 As shown, an electric dining table mechanism includes a mounting base 1, a turntable 2, and a drive assembly 4. The mounting base 1 is provided with a rotatable transmission ring 3, and the turntable 2 is mounted on the transmission ring 3.

[0035] The drive assembly 4 drives the transmission ring 3 to move, forming a transmission connection. The drive assembly 4 drives the transmission ring 3 to rotate, thereby causing the turntable 2 to rotate on the mounting chassis 1.

[0036] The mounting chassis 1 is provided with a second mounting structure 7 for assembling the drive assembly 4, and the drive assembly 4 is installed in the second mounting structure 7.

[0037] A second mounting structure 7 is provided on the mounting chassis 1, which can be detachably connected to the drive component 4. The drive component 4 is fixedly installed in the second mounting structure 7, which simplifies the installation process, makes installation more convenient and faster, reduces the installation difficulty, makes the whole mechanism more compact, and reduces the manufacturing cost. In addition, the area of ​​the dining table mechanism can be adjusted by installing the second mounting structure 7 on the outside or inside of the mounting chassis 1, so that it can be used for more dining tables and its application range is increased.

[0038] Specifically, the mounting chassis 1, turntable 2, and transmission ring 3 are all designed as hollow ring structures;

[0039] The drive assembly 4 includes a drive gear 401 and a gear ring 6 on the transmission ring 3;

[0040] The second mounting structure 7 includes a mounting base 701 located on the side of the mounting chassis 1. The mounting base 701 is on the same side as the gear ring 6, and the mounting base 701 has a notch 702 on the side near the gear ring 6.

[0041] The drive assembly 4 also includes a drive motor 402, which is installed in the mounting base 701. The drive motor 402 drives the drive gear 401 to rotate. The drive gear 401 is installed on one side of the notch 702 and meshes with the gear ring 6 through the notch 702 to form a transmission connection.

[0042] Mounting base 701 includes a fixed base body 703 located on the side of mounting chassis 1, the fixed base body 703 is provided with mounting holes 704, and the fixed base body 703 is detachably connected to a cover body 705;

[0043] The drive assembly 4 is installed onto the fixed base 703 through the mounting hole 704, and then the cover 705 is connected to the fixed base 703 to detachably install the drive assembly 4 into the mounting base 701.

[0044] Furthermore, the fixed base 703 is located on the upper side of the drive assembly 4, and the drive assembly 4 is installed inside the fixed base 703 from bottom to top, while the cover 705 is located on the lower side of the drive assembly 4.

[0045] The mounting base 703 and the cover 705 are provided with heat dissipation vents 706 to improve the heat dissipation performance of the drive component 4 and extend its service life.

[0046] Furthermore, the mounting chassis 1 is provided with a first mounting structure 5 for installation on its lower side. The first mounting structure 5 includes a mounting plate 501 located on the lower side of the mounting chassis 1. The mounting plate 501 is located parallel to the lower side of the mounting chassis 1 and extends toward one side of the mounting chassis 1.

[0047] Furthermore, the mounting base 1 has at least three support columns 502 on its lower side, and at least one support column 502 has a mounting plate 501 on its lower side. The mounting plate 501 extends to one side of the support column 502 and is parallel to the mounting base 1. The mounting plate 501 has a second mounting hole 503.

[0048] Furthermore, the support column 502 is designed as a hollow structure to save materials. A reinforcing column can also be added to the middle of the support column 502 to improve its supporting force and stability.

[0049] Furthermore, a limiting plate 8 is provided on the lower side of the turntable 2. The limiting plate 8 is located at the lower end of the turntable 2 and extends to the lower side of the mounting base 1. The limiting plate 8 is located on the opposite side of the second mounting structure 7.

[0050] Furthermore, the lower surface of the turntable 2 is provided with a first ball bearing slide 9, and the upper surface of the transmission ring 3 is provided with a second ball bearing slide 10. The first ball bearing slide 9 and the second ball bearing slide 10 are provided with a number of balls, and the turntable 2 is rotatably connected to the transmission ring 3 through a number of balls.

[0051] The lower surface of the transmission ring 3 is provided with a third ball bearing slide 11, and the mounting base 1 is provided with a fourth ball bearing slide 12. The third ball bearing slide 11 and the fourth ball bearing slide 12 are provided with a number of balls. The transmission ring 3 is rotatably connected to the mounting base 1 through the number of balls. By adopting this rotatable connection method of ball bearing slide and balls, the frictional resistance is reduced, making the turntable 2 rotate more smoothly.

[0052] A third ball bearing slide 11, a fourth ball bearing slide 12, and balls are provided between the transmission ring 3 and the mounting base 1, so that the drive gear 401 can drive the transmission ring 3 and the turntable 2 on the upper side of the transmission ring 3 to rotate on the upper side of the mounting base 1 through the gear ring 6.

[0053] A first ball bearing slide 9 and a second ball bearing slide 10, along with balls, are arranged between the transmission ring 3 and the turntable 2. The balls guide the rotation direction; due to their spherical structure and rolling characteristics, they ensure that the rotation direction of the turntable 2 is consistent with that of the transmission ring 3. This guiding effect prevents the turntable 2 from shifting or tilting during rotation, thus ensuring the smooth rotation of the tabletop.

[0054] The friction generated by the ball during rolling is much less than the sliding friction. When the transmission ring 3 rotates, the ball rolls between the turntable 2 and the transmission ring 3. This rolling friction makes force transmission more efficient and reduces energy loss. Lower friction means that the turntable 2 experiences less resistance when transmitting power, allowing it to rotate more smoothly. The spherical structure of the ball gives it high stability during rolling. Regardless of the rotational speed of the transmission ring 3, the ball maintains a stable rolling state. This stability prevents the turntable 2 from exhibiting significant shaking or jamming during rotation, thus ensuring the smooth rotation of the tabletop.

[0055] Because the contact between the balls and the turntable 2 and the transmission ring 3 is multi-point contact, and these contact points are evenly distributed, when the transmission ring 3 rotates, the force is evenly transmitted to the turntable 2 through the balls. This uniform force distribution ensures that the forces acting on the turntable 2 in all directions are relatively balanced, avoiding unstable rotation caused by uneven force distribution.

[0056] Its multi-point uniform contact also allows the ball bearings to withstand greater loads. During the use of the electric dining table, the tabletop on turntable 2 may bear a certain weight, such as tableware or food. The multi-point contact structure of the ball bearings can evenly distribute these loads to each contact point, thus ensuring that turntable 2 and the tabletop can still rotate smoothly under load.

[0057] In actual use, turntable 2 and transmission ring 3 may experience minor deformations due to various reasons (such as manufacturing errors, wear, etc.). The spherical structure of the balls gives them a certain degree of self-adaptability, enabling them to automatically adjust their position and rolling state to adapt to these minor deformations. This self-adaptability allows the balls to compensate for errors between components to a certain extent, thereby ensuring the smooth rotation of turntable 2.

[0058] The balls themselves have the characteristic of free rolling, allowing them to roll in any direction within their track. When the drive ring 3 rotates, the balls roll between the turntable 2 and the drive ring 3, transmitting the rotation of the drive ring 3 to the turntable 2. Since the rolling direction of the balls is independent, the turntable 2 can change its rolling direction as needed without directly affecting the rotation of the drive ring 3. Therefore, the turntable 2 can reverse or stop rotation by fine-tuning the balls while the drive ring 3 is rotating, thus stopping or reversing the rotation of the tabletop during its rotation.

[0059] like Figures 1 to 7 As shown in the figure, this is the first embodiment of the present invention. In this case, the gear ring 6 is an internal gear, and the mounting base 701...

[0060] Located inside the mounting base 1, the drive gear 401 meshes with the gear ring 6 from the inside to form a transmission connection. At this time, the drive component 4 is installed inside the mounting base 1. The structure is compact and more suitable for small electric dining tables. Multiple mounting bases 701 and drive components 15 can be provided and evenly distributed inside the mounting base 1.

[0061] In use, the drive assembly 4 is installed in the mounting base 701, so that the drive gear 401 meshes with the gear on the gear disk 6, and the cover 705 is connected to the fixed base 703 to complete the installation of the entire lower plate structure.

[0062] The third ball bearing slide 11, the fourth ball bearing slide 12 and the balls rotatably connect the mounting base 1 and the transmission ring 3. Then, the first ball bearing slide 9, the second ball bearing slide 10 and the balls rotatably connect the transmission ring 3 to the upper turntable 2. Then, a limiting plate 8 is installed on the outside of the turntable 2. The bottom end of the limiting plate 8 extends towards the mounting base 1 to the lower side of the mounting base 1 to prevent the turntable 2 from tilting or derailing, making the overall structure more stable and completing the installation of the entire dining table mechanism structure.

[0063] The mounting base 1 is then placed in a suitable position on the tabletop, and the mounting base 1 is fixed to the tabletop using bolts and other fasteners through the second mounting hole 503 on the mounting plate 501.

[0064] In addition, when the gear ring 6 is an external gear and the mounting base 701 is located on the outside of the mounting chassis 1, it is more suitable for large electric dining tables. Multiple mounting bases 701 and drive components 4 can be provided and evenly distributed on the outside of the mounting chassis 1.

[0065] This invention allows for quick and easy installation of the lower plate structure onto the dining table via the second mounting hole 503 on the mounting plate 501, greatly simplifying the installation process and improving efficiency. Simultaneously, the detachable design of the drive assembly 4 facilitates maintenance and component replacement, reducing maintenance costs. The multiple support feet 502 on the lower side enhance the stability of the lower plate structure, enabling it to better withstand the weight of the electric dining table and various forces during use. The overall lower plate structure is rationally designed, improving not only practicality but also aesthetics, and broadening its applicability.

[0066] 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.
