Description

Technical Field

[0001] This utility model relates to the field of catering equipment technology, and in particular to an electric dining table turntable. Background Technology

[0002] With the improvement of people's living standards and the diversification of social and dining occasions, there are higher requirements for the convenience, comfort, and fun of dining table use. In many scenarios such as family gatherings, business banquets, and hotel banquets, traditional manual turntables require diners to manually turn them to retrieve food. Not only is the operation sometimes not smooth, but frequent manual turning is also somewhat troublesome. Electric turntables rotate automatically and at a uniform speed, allowing people to easily and elegantly retrieve different dishes, meeting people's social demand for a convenient and efficient dining experience. In existing technologies, ordinary electric turntables cannot automatically adjust the direction of rotation of the table. The time that the dishes stay in front of the diners is relatively short, and the time for users to pick up the dishes is not sufficient. After the dishes pass in front of the users, they have to wait for the dishes to rotate once before they can taste them again, resulting in a poor user experience and failing to meet user needs. Utility Model Content

[0003] The purpose of this utility model is to provide an electric dining table turntable, which aims to solve at least one of the technical problems in the prior art.

[0004] To achieve the above objectives, the present invention provides an electric dining table turntable, comprising:

[0005] A turntable body, the turntable body including a rotating disk and a fixed disk, the rotating disk being rotatably mounted on top of the fixed disk;

[0006] A plurality of first ferromagnetic elements are arranged circumferentially on the rotating disk;

[0007] A sliding groove is provided on the fixed plate;

[0008] The second ferromagnetic element is slidably disposed in the sliding groove so that when the rotating disk rotates, the magnetic attraction between the first ferromagnetic element and the second ferromagnetic element drives the second ferromagnetic element to slide in the sliding groove.

[0009] A drive control component is disposed on the turntable body to drive the turntable to rotate.

[0010] A first Hall switch and a second Hall switch, wherein the first Hall switch is disposed opposite to the first end of the sliding groove, and the second Hall switch is disposed opposite to the second end of the sliding groove, and both the first Hall switch and the second Hall switch are electrically connected to the drive control component;

[0011] Specifically, when the second ferromagnetic component slides to the first end, it triggers the first Hall switch, causing the drive control component to control the rotating disk to rotate forward; when the second ferromagnetic component slides to the second end, it triggers the second Hall switch, causing the drive control component to control the rotating disk to rotate in reverse.

[0012] Furthermore, the bottom surface of the middle part of the sliding groove is higher than the bottom surface of the first end and the bottom surface of the second end.

[0013] Furthermore, the sliding groove is arranged along the rotation axis of the rotating disk in the length direction, so that when the rotating disk rotates, the plurality of the first ferromagnetic components pass sequentially from above the sliding groove through the first end and the second end.

[0014] Furthermore, the bottom surface of the rotating disk extends downward to form a plurality of mounting seats, which are spaced apart circumferentially, and the plurality of the first ferromagnetic components are embedded in the plurality of mounting seats one by one.

[0015] Furthermore, the turntable body also includes:

[0016] A gear disk is mounted on the rotating disk and is located between the rotating disk and the fixed disk. The drive control component is connected to the gear disk to drive the rotating disk to rotate. A second mounting ring groove is provided on the lower surface of the gear disk.

[0017] The second rolling element, the upper half of which is disposed within the second mounting ring groove;

[0018] The top of the fixed disk is provided with a second rolling ring groove, and the lower half of the second rolling element is disposed in the second rolling ring groove.

[0019] Furthermore, the fixed disk includes:

[0020] First shell;

[0021] A second housing is detachably mounted on the first housing to form a storage cavity between the second housing and the first housing. The drive control component is disposed in the storage cavity, and the storage cavity has a through hole on the side facing the gear disk to drive the drive control component to the gear disk through the through hole.

[0022] Furthermore, the rotating disk includes a rotating disk housing and a fastening protrusion, and a plurality of fastening protrusions are provided, which are circumferentially spaced at the inner peripheral edge of the bottom of the rotating disk housing;

[0023] The inner peripheral edge of the top of the fixed disk extends toward the center of the fixed disk to form an abutting flange, so that the rotating disk and the fixed disk are axially positioned by the fastening protrusion abutting against the abutting flange.

[0024] Furthermore, the top of the rotating disk housing is provided with multiple mounting slots spaced apart along the circumference, and each of the multiple mounting slots is provided with an anti-slip pad.

[0025] Furthermore, the top of the rotating disk housing is provided with patterned grooves.

[0026] Furthermore, the drive control component includes:

[0027] A gear set, the output end of which is meshed with the gear disk;

[0028] A drive motor, the output end of which is connected to the input end of the gear set;

[0029] A control circuit board is electrically connected to the first Hall switch, the second Hall switch, and the drive motor, so that when the first Hall switch is triggered, the control circuit board controls the drive motor to rotate forward, and when the second Hall switch is triggered, the control circuit board controls the drive motor to rotate in reverse.

[0030] As can be seen from the above technical solution, the electric dining table turntable of this utility model controls the rotation direction of the turntable through a drive control component. The first ferromagnetic component and the second ferromagnetic component can attract each other. The second ferromagnetic component being located at either the first or second end of the sliding groove triggers either the first or second Hall switch. When the first Hall switch is triggered, the drive control component controls the turntable to rotate forward; when the second Hall switch is triggered, the drive control component controls the turntable to rotate backward. When the second ferromagnetic component is located at the first end and the turntable rotates forward, multiple first ferromagnetic components pass sequentially over the sliding groove, and these components pass sequentially through the second end before passing through the first end. This keeps the second ferromagnetic component at the first end, thus... The rotating disc keeps rotating clockwise. When the user needs to rotate the disc in reverse, they manually turn it to rotate in the opposite direction. At this time, at least one first ferromagnetic component moves from the first end to the second end. The first ferromagnetic component drives the second ferromagnetic component to move to the second end, thus triggering the second Hall switch. This drives the control component to control the rotating disc to rotate in reverse. Multiple first ferromagnetic components pass through the first end and then the second end in sequence, keeping the second ferromagnetic component at the second end, so that the rotating disc keeps rotating in reverse. With this setting, diners can rotate the table according to their dining preferences so that their favorite dishes can be rotated to their front more quickly. This solves the problem of having to wait a long time for dishes to rotate back due to them being rotated too far, thus improving the diners' experience.

[0046] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Please refer to the following: Figures 1 to 8 This embodiment provides an electric dining table turntable, the key features of which include a turntable body 100, a plurality of first ferromagnetic elements 210, a sliding groove 310, second ferromagnetic elements, a drive control component 400, a first Hall switch, and a second Hall switch. The turntable body 100 includes a rotating disk 200 and a fixed disk 300. The rotating disk 200 is rotatably mounted on the top of the fixed disk 300. The plurality of first ferromagnetic elements 210 are circumferentially spaced on the rotating disk 200. The sliding groove 310 is disposed on the fixed disk 300. The second ferromagnetic elements are slidably disposed in the sliding groove 310, so that when the rotating disk 200 rotates, the magnetic attraction between the first ferromagnetic elements 210 and the second ferromagnetic elements drives the second ferromagnetic elements. The component slides within the sliding groove 310. The drive control component 400 is mounted on the turntable body 100 to drive the turntable 200 to rotate. A first Hall switch is positioned opposite to the first end 311 of the sliding groove 310, and a second Hall switch is positioned opposite to the second end 312 of the sliding groove 310. Both the first and second Hall switches are electrically connected to the drive control component 400. When the second ferromagnetic component slides to the first end 311, the first Hall switch is triggered, causing the drive control component 400 to control the turntable 200 to rotate forward. When the second ferromagnetic component slides to the second end 312, the second Hall switch is triggered, causing the drive control component 400 to control the turntable 200 to rotate in reverse.

[0048] The rotation direction of the rotating disk 200 is controlled by the drive control component 400. The first ferromagnetic element 210 and the second ferromagnetic element can attract each other. The second ferromagnetic element is located at the first end 311 or the second end 312 in the sliding groove 310, which triggers the first Hall switch or the second Hall switch. When the first Hall switch is triggered, the drive control component 400 controls the rotating disk 200 to rotate forward; when the second Hall switch is triggered, the drive control component 400 controls the rotating disk 200 to rotate in reverse. When the second ferromagnetic element is located at the first end 311 and the rotating disk 200 rotates forward, multiple first ferromagnetic elements 210 pass over the sliding groove 310 in sequence, and the multiple first ferromagnetic elements 210 pass through the second end 312 and then the first end 311 in sequence. In this way, the second ferromagnetic element is held at the first end 311, so that the rotating disk 200 is kept in place. The rotating disk 200 rotates in the forward direction. When the user needs to rotate the disk 200 in reverse, they manually turn the disk 200 to rotate in the opposite direction. At this time, at least one first ferromagnetic component 210 moves from the first end 311 to the second end 312. The first ferromagnetic component 210 will drive the second ferromagnetic component to move to the second end 312. This triggers the second Hall switch, which drives the control component 400 to control the rotating disk 200 to rotate in reverse. Multiple first ferromagnetic components 210 pass through the first end 311 and then the second end 312 in sequence, keeping the second ferromagnetic component at the second end 312, so that the rotating disk 200 continues to rotate in reverse. With this setting, diners can rotate the table according to their dining preferences so that their favorite dishes can be rotated to their front more quickly. This solves the problem of having to wait a long time for the dishes to rotate back due to them being rotated too far, and improves the dining experience.

[0049] In this embodiment, at least one of the first ferromagnetic component 210 and the second ferromagnetic component is made of magnetic material, so that when the first ferromagnetic component 210 passes over the sliding groove 310, the second ferromagnetic component will move with the first ferromagnetic component 210. The magnetic material can be a magnet or a magnetic stone, and the shape of the second ferromagnetic component can be a bead, a cube, or the like.

[0050] The first Hall switch is positioned opposite to the first end 311 of the sliding groove 310, and the second Hall switch is positioned opposite to the second end 312 of the sliding groove 310. The first Hall switch is positioned so that it can be triggered by the second ferromagnetic component that slides to the first end 311, and the second Hall switch is positioned so that it can be triggered by the second ferromagnetic component that slides to the second end 312.

[0051] Preferably, the bottom surface of the middle part of the sliding groove 310 is higher than the bottom surface of the first end 311 and the bottom surface of the second end 312.

[0052] This design reduces the impact of the second ferromagnetic component sliding under gravity on the first or second Hall switch when the electric dining table turntable is not placed horizontally, thus improving the anti-interference capability of the electric dining table turntable.

[0053] Preferably, such as Figure 3 As shown, the sliding groove 310 is arranged around the rotation axis of the rotating disk 200 in the length direction, so that when the rotating disk 200 rotates, multiple first ferromagnetic components 210 pass through the first end 311 and the second end 312 sequentially from above the sliding groove 310.

[0054] With this configuration, during rotation, the first ferromagnetic component 210 can accurately drive the second ferromagnetic component to slide within the sliding groove 310 at the corresponding position, thereby triggering the corresponding first Hall switch or second Hall switch to control the forward or reverse rotation of the rotating disk 200, making the rotation control more precise and stable, and avoiding abnormal rotation of the rotating disk 200 due to misalignment between the ferromagnetic components.

[0055] Preferably, such as Figure 7 As shown, the bottom surface of the rotating disk 200 extends downward to form a plurality of mounting seats 220, which are spaced apart circumferentially, and a plurality of first ferromagnetic components 210 are embedded in the plurality of mounting seats 220 in a corresponding manner.

[0056] The first ferromagnetic component 210 is embedded in the mounting base 220 extending downward from the bottom of the rotating disk 200, which can effectively fix the first ferromagnetic component 210. During the continuous rotation of the rotating disk 200, the first ferromagnetic component 210 will not easily loosen, shift, or even fall off, ensuring the stability of its connection with the rotating disk 200. This makes the entire electric dining table turntable structure more reliable and can operate stably for a long time. It avoids problems such as loosening of the ferromagnetic component affecting its subsequent cooperation with the second ferromagnetic component and the realization of the rotation control function of the rotating disk 200. In addition, this corresponding embedding method between the mounting base 220 and the first ferromagnetic component 210 facilitates the assembly of parts during the manufacturing process and improves production efficiency.

[0057] In this embodiment, please refer to the following: Figures 1 to 8 The turntable body 100 also includes a gear disk 110 and a second rolling element 130. The gear disk 110 is mounted on the rotating disk 200 and is located between the rotating disk 200 and the fixed disk 300. The drive control component 400 is driven and connected to the gear disk 110 so as to drive the rotating disk 200 to rotate. The lower surface of the gear disk 110 is provided with a second mounting ring groove. The upper half of the second rolling element 130 is disposed in the second mounting ring groove. The top of the fixed disk 300 is provided with a second rolling ring groove 330, and the lower half of the second rolling element 130 is disposed in the second rolling ring groove 330. In addition, in one embodiment, the gear disk 110 and the rotating disk 200 can be fixedly mounted relative to each other. The drive control component 400 is driven and connected to the gear disk 110, and the gear disk 110 drives the rotating disk 200 to rotate.

[0058] The second rolling element 130 includes a frame and a ball. The frame has a ball groove, and the ball is rotatably installed in the ball groove. By installing a second annular groove on the lower surface of the gear disk 110, the rotating disk 200 rotates relative to the fixed disk 300 through rolling friction, which reduces the rotational resistance of the rotating disk 200. Moreover, the assembly structure set in this way is simple and conducive to improving production efficiency.

[0059] Furthermore, please refer to the following: Figures 1 to 5 The fixed disk 300 includes: a first housing 340 and a second housing 350. The second housing 350 is detachably mounted on the first housing 340 to form a storage cavity 360 between the second housing 350 and the first housing 340. The drive control assembly 400 is disposed in the storage cavity 360. The storage cavity 360 has a through hole 370 on the side facing the gear disk 110 so as to drive the drive control assembly 400 to the gear disk 110 through the through hole 370.

[0060] The storage cavity 360 formed between the second housing 350 and the first housing 340 allows the drive control component 400 to be placed in an orderly manner within the storage cavity 360. The drive connection to the gear disk 110 is achieved through the through hole 370, ensuring the rationality of the connections between components and avoiding the risk of damage to exposed wiring and other components. This makes the internal structure of the entire electric dining table turntable more regular and orderly, improving the overall stability and safety of the product. Furthermore, the storage cavity 360 provides a relatively independent and enclosed space for the drive control component 400, effectively preventing the entry of external dust, moisture, and other debris. This prevents these impurities from causing corrosion, short circuits, or interference with the normal operation of precision components such as electronic components, motors, and gear sets 410 within the drive control component 400, extending its service life and improving its operational stability and reliability. The second housing 350 is detachable from the first housing 340, simplifying the repair and maintenance of the drive control component 400.

[0061] In this embodiment, please refer to the following: Figures 1 to 7 The rotating disk 200 includes a rotating disk 200 housing and a fastening protrusion 250. Multiple fastening protrusions 250 are provided and are circumferentially spaced on the inner peripheral edge of the bottom of the rotating disk housing 240. The inner peripheral edge of the top of the fixed disk 300 extends toward the center of the fixed disk 300 to form an abutment flange 380, so that the rotating disk 200 and the fixed disk 300 are axially positioned by the fastening protrusions 250 abutting against the abutment flange 380.

[0062] The rotating disk 200 is positioned between the fixed disk 300 by the snap-fit ​​protrusion 250, and the rotating disk 200 can be disassembled from the fixed disk 300 in this way. During the production and assembly process, the snap-fit ​​connection can reduce the assembly difficulty and improve production efficiency. By releasing the engagement between the snap-fit ​​protrusion 250 and the abutment flange 380, the rotating disk 200 can be disassembled relatively smoothly, which facilitates the maintenance of each component and reduces the difficulty and cost of later maintenance.

[0063] Furthermore, such as Figure 6 As shown, the top of the rotating disk 200 body is provided with a patterned groove 241.

[0064] The presence of the patterned groove 241 gives the top of the turntable housing 240 a unique texture and pattern, making the entire electric dining table turntable look more refined and stylish, which helps to improve the product's competitiveness. In addition, the patterned groove 241 can reduce the amount of material used for shaping, thereby reducing production costs and improving product efficiency.

[0065] Furthermore, the top of the rotating disk 200 body is provided with multiple mounting slots 242 at intervals along the circumference, and each of the multiple mounting slots 242 is provided with anti-slip rubber pads 243.

[0066] The rotating table is placed on top of the rotating plate housing 240. The anti-slip pad 243 can increase the friction between the rotating table and the rotating plate housing 240, preventing the rotating table from shifting unexpectedly when rotating. The anti-slip pad 243 also acts as a buffer between the rotating table and the rotating plate housing 240. The anti-slip pad 243 is made of elastic anti-slip material.

[0067] In this embodiment, please refer to the following: Figures 2 to 8 The drive control component 400 includes: a gear set 410, a drive motor 420, a control circuit board, a buzzer, a first indicator light, and a second indicator light. The output end of the gear set 410 is meshed with the gear disk 110, and the output end of the drive motor 420 is driven by the input end of the gear set 410. The control circuit board is electrically connected to the first Hall switch, the second Hall switch, and the drive motor 420, so that when the first Hall switch is triggered, the control circuit board controls the drive motor 420 to rotate forward, and when the second Hall switch is triggered, the control circuit board controls the drive motor 420 to rotate in reverse.

[0068] Control circuit board functions: When the first Hall switch is triggered, the control circuit board controls the drive motor 420 to rotate forward, the first indicator light illuminates, and the buzzer beeps briefly. When the second Hall switch is triggered, the control circuit board controls the drive motor 420 to rotate in reverse, the second indicator light illuminates, and the buzzer beeps briefly. When neither the first nor the second Hall switch is activated, the drive motor 420 stops, no indicator light illuminates, and the buzzer beeps for 1 second. Regardless of whether the drive motor 420 rotates forward or reverse, it stops working after a two-hour delay. It resumes working after switching or reactivating the first or second Hall switch for two hours.

[0069] Among them, the gear set 410 achieves the purpose of speed reduction through multiple gear transmissions, so that the drive motor 420 can drive the rotating table of the dining table to rotate.

[0070] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: the rotation direction of the rotating disk 200 is controlled by the drive control component 400, and the first ferromagnetic component 210 and the second ferromagnetic component can attract each other. The second ferromagnetic component is located at the first end 311 or the second end 312 in the sliding groove 310 to trigger the first Hall switch or the second Hall switch. When the first Hall switch is triggered, the drive control component 400 controls the rotating disk 200 to rotate forward, and when the second Hall switch is triggered, the drive control component 400 controls the rotating disk 200 to rotate backward. When the second ferromagnetic component is located at the first end 311 and the rotating disk 200 rotates forward, multiple first ferromagnetic components 210 pass over the sliding groove 310 in sequence, and multiple first ferromagnetic components 210 pass the second end 312 and then the first end 311 in sequence. In this way, the second ferromagnetic component will be held in place. The first end 311 keeps the rotating disk 200 rotating forward. When the user needs to rotate the disk 200 in reverse, they manually turn the disk 200 to rotate in the opposite direction. At this time, at least one first ferromagnetic element 210 moves from the first end 311 to the second end 312. The first ferromagnetic element 210 will drive the second ferromagnetic element to move to the second end 312. This triggers the second Hall switch, driving the control component 400 to control the rotating disk 200 to rotate in reverse. Multiple first ferromagnetic elements 210 pass through the first end 311 and then the second end 312 in sequence, keeping the second ferromagnetic element at the second end 312, so that the rotating disk 200 keeps rotating in reverse. With this setting, diners can rotate the table according to their dining preferences so that their favorite dishes can be rotated to their front more quickly. This solves the problem of having to wait a long time for the dishes to rotate back because they have been rotated too far, and improves the dining experience.
