Description

Technical Field

[0001] This utility model relates to the field of electric dining table technology, specifically to an electric dining table structure. Background Technology

[0002] In large dining settings, rotating plates are commonly used on tables to allow food to circulate and be easily accessible to diners. This design can also be used at home. For added convenience, the plates can even rotate on their own.

[0003] Chinese patent CN214230292U discloses a rotating dining table turntable and a rotating dining table turntable device, including a bottom cover, a top cover, and a gear ring body. The center points of the bottom cover, the top cover, and the gear ring body coincide. The gear ring body is installed between the bottom cover and the top cover. When driven by a motor, the gear ring body rotates with its center point as the rotation center. When the gear ring body rotates, it drives the top cover to rotate, while the bottom cover remains stationary. This technical solution uses a motor device to drive the gear ring body to rotate, and the rotation of the gear ring body simultaneously drives the top cover to rotate, thereby realizing the rotation function of the top cover, allowing the food placed on the top cover to rotate with the rotation of the top cover.

[0004] In the aforementioned prior art, the size and number of teeth of the gear ring are fixed, thus the rotational speed of the top cover and the plate is also fixed. However, in practice, due to the diverse sizes and specifications of dining tables and plates, the same rotational speed will result in different rotational speeds (linear velocities) of the food on the plate. This necessitates customizing corresponding gear specifications or motor speed ratios to adapt to the table / plate specifications, leading to poor compatibility. The large number of specifications also makes production and maintenance very troublesome, making it difficult to reduce costs.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0022] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1-4 As shown, the electric dining table structure of this utility model includes a tabletop 4, a mechanism assembly, and a plate 41. The tabletop 4 has a frame 42 underneath and a first slot 43 on it. The mechanism assembly is located in the first slot 43 and fixedly connected to the frame 42. The plate 41 is rotatably mounted on the mechanism assembly. The mechanism assembly has a second slot 44, an internal gear ring 21, and an external gear ring 22. The frame 42 has at least one drive motor 12, and the drive motor 12 has a drive gear 13. At least one drive motor 12 is located in the first slot 43 and / or the second slot 44, thereby being connected to the internal gear ring 21 and / or the external gear ring 22 through the drive gear 13.

[0024] The table 4 and plate 41 described in this utility model are conventional dining tables used in catering establishments. The table 4 has a supporting frame 42 underneath, and the frame 42 is equipped with table legs 46 to maintain balance. It can be understood that the drive motor 12 can drive the internal gear ring 21 and / or the external gear ring 22 to rotate through the drive gear 13, thereby driving the plate 41 on the mechanism assembly to rotate.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] The mechanism assembly includes a chassis 1 and a turntable 11. The chassis 1 is fixedly mounted on the frame 42. A rotatable transmission ring 2 is provided on the chassis 1. The turntable 11 is mounted on the transmission ring 2. A plate 41 is mounted on the turntable 11. The second empty space 44 is located inside the chassis 1. An internal gear ring 21 is located on the inner wall of the transmission ring 2. An external gear ring 22 is located on the outer wall of the transmission ring 2. The drive gear 13 on the drive motor 12 can mesh with the internal gear ring 21 and / or the external gear ring 22.

[0029] 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.

[0030] 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.

[0031] The transmission ring 2 includes a flange ring 23, a first clamping sleeve 24, and a second clamping sleeve 25. 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 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.

[0032] Furthermore, the transmission ring 2 also includes a ring clamp 3, which 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 located on the outer wall of the ring clamp 3. It can be understood that 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.

[0033] 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.

[0034] 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 side wall of the first sleeve 24 and the outer side wall of the chassis 1. A plurality of balls are provided in the first ball groove 14, and the first sleeve 24 is rotatably connected to the chassis 1 through the plurality of balls. The plurality of balls in the first ball groove 14 make the first sleeve 24 and the chassis 1 rotatably connected, that is, the first sleeve 24 and the chassis 1 form a bearing structure, and the balls can provide good stability, so that the plate can rotate smoothly.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] The second sleeve 25 is arranged around the outer side of the turntable 11. A second ball groove 15 is provided between the inner sidewall of the second sleeve 25 and the outer sidewall of the turntable 11. A plurality of balls are provided in the second ball groove 15, and the second sleeve 25 is rotatably connected to the turntable 11 through the plurality of balls. It can be understood that when the drive motor 12 drives the internal gear ring 21 or the external gear ring 22, it can drive the second 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 sleeve 25, and a non-rigid rotatable connection is formed by the plurality of balls, so that the turntable 11 and the second 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 sleeve 25, thus avoiding affecting the operation of the transmission ring 2 and the drive motor 12.

[0040] The turntable 11 is provided with at least three tray supports 16, which are equidistant from the rotation center axis of the turntable 11. Each tray support 16 is provided with an anti-slip pad 17. The number of tray supports 16 can be set according to the size of the plate. Typically, five tray supports 16 are provided on the turntable 11 to provide support for the plate 41. The anti-slip pads 17 enhance the friction between the tray supports 16 and the plate 41, making the plate 41 more stable on the turntable 11.

[0041] The frame 42 includes a beam 45, with the table 4 fixedly connected to the beam 45. Table legs 46 are located beneath the beam 45. The frame 42 is primarily used for the installation of the aforementioned mechanism components. The fixed connection between the frame 42 and the table 4 ensures that the first empty space 43 and the second empty space 44 are concentrically positioned, allowing the drive motor 12 to be installed within these spaces and fixedly connected to the frame 42. It is understood that the beam 45 surrounds the outside of the frame 42, making the table 4 more stable and increasing its load-bearing capacity.

[0042] 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.
