[0020] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-4 As shown, the foldable electric turntable dining table of this utility model includes a tabletop 4, a plate 41, and a mechanism assembly. The mechanism assembly is disposed on the tabletop 4, and the plate 41 is placed on the mechanism assembly. The mechanism assembly can drive the plate 41 to rotate on the tabletop 4. The tabletop 4 is foldable and deformable. A fixed frame 42 is provided under the tabletop 4 and is connected to the tabletop 4. Both ends of the fixed frame 42 are provided with table legs 43. Movable frames 44 are provided on both sides of the fixed frame 42. A cross connector 45 is provided on the fixed frame 42. The first end of the movable frame 44 is hinged to the cross connector 45. The movable frame 44 is connected to the top of the tabletop 4, and the second end of the movable frame 44 is provided with table legs 43.

[0022] Understandably, the fixed frame 42 and the two movable frames 44 form a cross-shaped structure, and the table 4 is supported by four table legs 43 to maintain balance. The mechanism can drive the plate 41 to rotate on the table 4, so that the food on the plate 41 rotates around the center to facilitate eating for guests.

[0023] Preferably, the movable frame 44 is hinged to the cross connector 45, so that the movable frame 44 can rotate 90° relative to the fixed frame 42, thereby bringing the table legs 43 on the movable frame 44 together with the table legs 43 on the fixed frame 42 to reduce the overall volume.

[0024] Furthermore, the movable frame 44 and the table 4 are connected at the top and can move relative to each other. When the movable frame 44 is folded into the fixed frame 42, the table 4 can be folded and deformed. The folding method of the table 4 can refer to the prior art, which will be described later.

[0025] Furthermore, the mechanism assembly is mounted on the table 4, and the plate 41 is placed on the mechanism assembly so that it can be detached, thereby facilitating the folding and transportation of the table 4.

[0026] Specifically, the fixed frame 42 includes an upper beam 421 and a lower beam 422. The upper beam 421 is set along the bottom surface of the table 4 and is connected to it. The lower beam 422 is located below the upper beam 421 and is parallel to the upper beam 421. The two ends of the upper beam 421 and the lower beam 422 are respectively connected to the corresponding table legs 43. Both the upper beam 421 and the lower beam 422 are provided with cross connectors 45. The first end of the movable frame 44 is hinged to the two cross connectors 45 respectively. The upper beam 421, the lower beam 422 and the two table legs 43 form a frame structure. The table legs 43 stand on the ground, and the upper beam 421 is assembled and connected to the bottom surface of the table 4.

[0027] The movable frame 44 includes an upper swing arm 441 and a lower swing arm 442. The upper swing arm 441 is arranged along the bottom surface of the table 4 and is connected to its top. The first end of the upper swing arm 441 is hinged to the cross connector 45 on the upper beam 421. The lower swing arm 442 is located below the upper swing arm 441 and is parallel to the upper swing arm 441. The first end of the lower swing arm 442 is hinged to the cross connector 45 on the lower beam 422. The second ends of the upper swing arm 441 and the lower swing arm 442 are respectively connected to the corresponding table legs 43. The lower end of the table legs 43 is provided with casters 431. As mentioned above, the upper swing arm 441, the lower swing arm 442, and the table leg 43 also form a frame structure. Both the upper swing arm 441 and the lower swing arm 442 are hinged to the cross connector 45, so that the movable frame 44 can rotate 90° relative to the fixed frame 42. The movable frame 44 can support the table 4 when unfolded, and the movable frame 44 can be folded up to facilitate the movement of the table 4.

[0028] Preferably, the bottom surface of the table 4 is provided with at least two card slots 401, each card slot 401 having a downward-facing slot. The upper beam 421 passes through the slot, thereby forming a detachable connection between the upper beam 421 and the table 4 via the card slots 401. The upper swing arm 441 is provided with a pad 17, and the upper swing arm 441 is connected to the table 4 by contacting the pad 17. The upper beam 421 passes through the slot and forms a detachable connection with the card slot 401, and the upper swing arm 441 supports the table 4 via the pad 17, also forming a detachable connection, allowing the movable frame 44 to move relative to the table 4. In particular, the table 4 can also be separated from the fixed frame 42 and the movable frame 44, making the table 4 and the table legs 43 form an assemblable and separable mode, making it easier to transport and stack.

[0029] Specifically, the table 4 includes a center section 402 and side panels 403. Side panels 403 are provided on both sides of the center section 402, and the center section 402 and side panels 403 are connected by several hinges 404. The fixed frame 42 is connected to the center section 402, and two movable frames 44 respectively abut against the corresponding side panels 403. A first empty space 46 is provided in the middle of the center section 402, and the mechanism assembly is disposed within the first empty space 46, and the mechanism assembly is fixedly connected to the fixed frame 42. The center section 402 and the two side panels 403 form a circular table 4, allowing the table 4 to be folded and unfolded. Furthermore, the fixed frame 42 is arranged along the center section 402. After the movable frames 44 are folded up, the two side panels 403 can hang on both sides of the center section 402, allowing the table 4 to be moved and transported by the casters 431 on the table legs 43, and allowing multiple tables 4 to be stacked against a wall in a folded state, making them more convenient and efficient to use.

[0030] The mechanism assembly includes a chassis 1, a turntable 11, and a drive motor 12. The chassis 1 is fixedly mounted on the upper beam 421. A rotatable transmission ring 2 is provided on the chassis 1. The turntable 11 is rotatably mounted on the transmission ring 2. The plate 41 is detachably mounted on the turntable 11. A second cavity 47 is provided inside the chassis 1. An internal gear ring 21 is provided on the inner wall of the transmission ring 2, and an external gear ring 22 is provided on the outer wall of the transmission ring 2. A drive gear 13 is provided on the drive motor 12. The drive gear 13 can be located in the first cavity 46 or the second cavity 47 to mesh with the internal gear ring 21 and / or the external gear ring 22.

[0031] The table 4 has a first empty space 43 at its center, which is used to install the mechanism assembly. The mechanism assembly has a second empty space 44. The outer gear ring 22 and the inner gear ring 21 correspond to the first empty space 43 and the second empty space 44, respectively, so that the drive motor 12 can be installed in the first empty space 43 or the second empty space 44, respectively, and engage the inner gear ring 21 or the outer gear ring 22 through the drive gear 13.

[0032] It is understood that the inner gear ring 21 and the outer gear ring 22 are concentrically arranged on the mechanism assembly and are paired internally and externally. The inner gear ring 21 and the outer gear ring 22 have different diameters, and naturally, different numbers of teeth. When the drive gear 13 meshes with the inner gear ring 21 or the outer gear ring 22, different rotational speeds can be output. Specifically, when the drive motor 12 is located in the first empty space 43, the drive gear 13 meshes with the outer gear ring 22, which has more teeth, allowing the mechanism assembly to operate at a lower speed to accommodate larger plates 41. When the drive motor 12 is located in the second empty space 44, the drive gear meshes with the inner gear ring 22, which has fewer teeth, allowing the mechanism assembly to operate at a higher speed to accommodate smaller plates 41.

[0033] Furthermore, multiple drive motors 12 can be installed in the first empty space 43 and the second empty space 44 to drive the internal gear ring 21 or the external gear ring 22, thereby outputting higher torque to meet the needs of the dining table.

[0034] The transmission ring 2 of this invention has an inner gear ring 21 and an outer gear ring 22 on its inner and outer sides, respectively. The drive motor 12 can be connected to either the inner gear ring 21 or the outer gear ring 22 through the engagement of the drive gear 13, thereby driving the turntable 11 to rotate. It is understood that due to the difference in the inner and outer diameters of the transmission ring 2, while maintaining the same tooth profile, the number of teeth on the outer gear ring 22 is greater than the number of teeth on the inner gear ring 21. This allows the transmission ring 2 to achieve at least two transmission ratios, driving the turntable 11 to output different speeds according to the specifications of the plates.

[0035] Specifically, when used on large dining tables, the drive gear 13 on the drive motor 12 meshes with the outer gear ring 22, driving the turntable 11 to rotate at a lower speed via the transmission ring 2. When used on small dining tables, the drive gear 13 on the drive motor 12 meshes with the inner gear ring 21, driving the turntable 11 to rotate at a higher speed via the transmission ring. By controlling the transmission ratio of the transmission ring 2, the linear velocity of plates of different sizes can be effectively controlled, ensuring the time each dish spends in front of the diner.

[0036] The transmission ring 2 includes a flange ring 23, a first clamping sleeve 24, a second clamping sleeve 25, and a ring clamp 3. The first clamping sleeve 24 and the second clamping sleeve 25 are spaced apart vertically. The first clamping sleeve 24 is rotatably connected to the chassis 1, and the turntable 11 is rotatably mounted on the second clamping sleeve 25. The flange ring 23 is clamped and fixed between the first clamping sleeve 24 and the second clamping sleeve 25, and the first clamping sleeve 24, the flange ring 23, and the second clamping sleeve 25 are concentrically arranged. An internal gear ring 21 is disposed on the inner wall of the flange ring 23. The first clamping sleeve 24, the flange ring 23, and the second clamping sleeve 25 are all annular structures and are stacked sequentially from bottom to top. The first clamping sleeve 24, the flange ring 23, and the second clamping sleeve 25 are interconnected to form an assembly. The inner ring of the flange ring 23 passes through the chassis 1 and the turntable 11, causing the internal gear ring 21 to protrude, facilitating the meshing connection between the drive gear 13 and the internal gear ring 21.

[0037] Furthermore, the ring clamp 3 is fitted onto the outer walls of the first clamp 24 and the second clamp 25. A bushing 31 is provided on the inner wall of the ring clamp 3, and the bushing 31 is clamped and fixed between the first clamp 24 and the second clamp 25. An external gear ring 22 is provided on the outer wall of the ring clamp 3. The ring clamp 3, when mounted on the first clamp 24 and the second clamp 25, can control concentricity. The bushing 31 facilitates the assembly of the ring clamp 3, as shown in the attached figure. Figure 2 As shown, the first jacket 24 is paired and connected to the chassis 1, and the flange ring 23 and the ring clamp 3 are stacked on the first jacket 24. Then, the second jacket 25 is assembled inside the ring clamp 3, so that the first jacket 24 and the second jacket 25 are concentrically arranged. Usually, multiple bolts are threaded between the first jacket 24, the bushing 31, the flange ring 23 and the second jacket 25, and they are connected to form a component, which can improve the assembly accuracy.

[0038] Furthermore, the external gear ring 22 is mounted on the ring clamp 3, thus forming a concentric arrangement with the internal gear ring 21 on the flange ring 23. The external gear ring 22 can be replaced with other parts of the same diameter but different numbers of teeth via the ring clamp 3. That is, the external gear ring 22 and the ring clamp 3 are an integral structure. The ring clamp 3 can be configured with external gear rings 22 of different numbers of teeth for the same diameter, thereby achieving flexible replacement of parts to meet different product requirements.

[0039] The aforementioned transmission ring 2 is rotatably connected to the chassis 1. Preferably, the first sleeve 24 is arranged around the outer side of the chassis 1, and a first ball groove 14 is provided between the inner sidewall of the first sleeve 24 and the outer sidewall of the chassis 1; the first ball groove 14 contains a plurality of balls, and the first sleeve 24 is rotatably connected to the chassis 1 through the plurality of balls. The second sleeve 25 is arranged around the outer side of the turntable 11, and a second ball groove 15 is provided between the inner sidewall of the second sleeve 25 and the outer sidewall of the turntable 11; the second ball groove 15 contains a plurality of balls, and the second sleeve 25 is rotatably connected to the turntable 11 through the plurality of balls.

[0040] The first ball groove 14 is provided with a number of balls so that the first sleeve 24 and the chassis 1 form a rotatable connection, that is, the first sleeve 24 and the chassis 1 form a bearing structure. The balls can provide good stability, so that the plate can rotate smoothly.

[0041] Specifically, the friction generated by the rolling ball during rolling is much smaller than the sliding friction. When the transmission ring 2 rotates, the rolling friction makes the force transmission more efficient and reduces energy loss. The smaller friction means that the transmission ring 2 experiences less resistance when transmitting power, avoiding vibration or jamming between the transmission ring 2 and the chassis 1, and ensuring that the plate can rotate more smoothly.

[0042] Furthermore, multiple balls can roll freely within the first ball groove 14, resulting in multi-point contact between the first sleeve 24 and the chassis 1, with the force points evenly distributed. This ensures that the force on the transmission ring 2 is basically balanced in all directions, avoiding unstable rotation caused by uneven force distribution. Moreover, more balls can provide greater load-bearing capacity.

[0043] In particular, there is a gap between the ball and the ball groove. The first ball groove 14 can constrain the rolling trajectory of the ball and prevent shaking and deviation.

[0044] Preferably, the mating surfaces formed by the outer sidewall of the chassis 1 and the inner sidewall of the first sleeve 24 can be inclined planes, that is, the diameters of the outer sidewall of the chassis 1 and the inner sidewall of the first sleeve 24 gradually increase from top to bottom. The force exerted by the first sleeve 24 on the chassis 1 may have a component force tending towards the center of rotation, so that the first sleeve 24 and the chassis 1 can be mutually constrained and maintain a concentric state.

[0045] It is understood that when the aforementioned drive motor 12 drives the internal gear ring 21 or the external gear ring 22, it can drive the second clamping sleeve 25 and the turntable 11 to rotate synchronously. Preferably, a second ball groove 15 is also provided between the turntable 11 and the second clamping sleeve 25, and a non-rigid rotational connection is formed by several balls, so that the turntable 11 and the second clamping sleeve 25 can rotate relative to each other. If the diner applies external force to stop or reverse the plate and the turntable 11, it will not affect the rotation of the second clamping sleeve 25, thus avoiding affecting the operation of the transmission ring 2 and the drive motor 12.

[0046] The turntable 11 is provided with at least three tray supports 16 for supporting plates 41. The at least three tray supports 16 are arranged at equal angular intervals around the rotation center axis of the turntable 11, and each tray support 16 is provided with a pad 17. The number of tray supports 16 can be set according to the size of the plate. Generally, five tray supports 16 are provided on the turntable 11 to provide load-bearing capacity for the plate 41. The pads 17 can enhance the friction between the tray supports 16 and the plate 41, so that the plate 41 is placed more stably on the turntable 11. Of course, the plate 41 can also be directly separated from the tray supports 16 for easy disassembly, assembly, and handling.

[0047] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
