Description

Technical Field

[0001] This utility model relates to the field of electric dining table technology, specifically to an electric turntable mechanism 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, and the rotational speed of the gear ring is also fixed under the drive of the motor. However, in actual use, dining tables and turntables come in various sizes and specifications. The same turntable rotational speed will result in different rotational speeds (linear velocities) of the dishes on the table. Different gear rings or motor speed ratios are required to adapt to the specifications of the plates, resulting in poor compatibility and high application costs.

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

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

[0021] like Figure 1-2 As shown, the electric turntable mechanism structure of this utility model includes a chassis 1, a turntable 11, and a drive motor 12. The chassis 1 is provided with a rotatable transmission ring 2, and the turntable 11 is mounted on the transmission ring 2. The inner wall of the transmission ring 2 is provided with an inner gear ring 21, and the outer wall of the transmission ring 2 is provided with an outer gear ring 22. The drive motor 12 is provided with a drive gear 13, which can mesh with the inner gear ring 21 and / or the outer gear ring 22 to form a transmission connection, thereby driving the turntable 11 to rotate on the chassis 1.

[0022] It is well known that the tabletops and rotating trays used in restaurants are relatively large and vary in size, such as tables for 10, 15, or 20 people, while home dining tables are typically smaller. This leads to a problem: existing rotating trays need to be customized and matched to the tabletop size. Furthermore, the matching process doesn't focus on the tray's load-bearing capacity or the motor's output torque, but rather on the varying rotational speeds of the food placed on the trays, even when the rotating tray's rotation speed is constant. Consequently, there are numerous rotating tray mechanism specifications on the market, increasing the number of parts, the variety of items in stock, and warehousing costs for manufacturers.

[0023] 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 rotational speed of 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 rotational speeds according to the specifications of the plates.

[0024] 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.

[0025] Alternatively, there may be multiple drive motors 12. It is understood that the installation positions of the drive motors 12 can be flexibly arranged. Multiple drive motors 12 respectively drive the transmission ring 2 and the turntable 11 by meshing the internal gear ring 21 and the external gear ring 22 through the drive gear 13, thereby achieving higher output torque while ensuring transmission stability.

[0026] 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 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.

[0027] 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 steel ring 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.

[0028] 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.

[0029] 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. 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 these balls. The presence of balls in the first ball groove 14 enables the first sleeve 24 to be rotatably connected to the chassis 1, meaning the first sleeve 24 and the chassis 1 form a bearing structure. The balls provide excellent stability, allowing the plate to rotate smoothly.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] The turntable 11 is provided with at least three tray supports 16, which are equidistant from the rotation center axis of the turntable 11. 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.

[0036] As described above, the installation position and number of drive motors 12 can be flexibly set according to actual needs. The bottom surface of the chassis 1 is provided with a base plate 17. The drive motors 12 are located inside the transmission ring 2 and are fixedly connected to the base plate 17, so that the drive gear 13 meshes with the internal gear ring 21. Setting the drive motors 12 on the base plate 17 and making the drive gear 13 mesh with the internal gear ring 21 can save installation space.

[0037] Furthermore, the chassis 1 is mounted on the desktop frame 18, and the drive motor 12 is located on the outside of the transmission ring 2 and fixedly connected to the desktop frame 18, thereby enabling the drive gear 13 to mesh with the external gear ring 22. When applied to large-sized desktops, the drive motor 12 can be mounted on the outside of the transmission ring 2, or the number of drive motors 12 can be increased to provide greater output torque.

[0038] 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.
