Description

Technical Field

[0001] The invention is applicable to the field of catering equipment and provides a rotating dining table with a stop sensing function. Background Art

[0002] In order to meet the needs of customers with more than a dozen or even more people dining at the same table, restaurants are usually equipped with electric revolving tables. The electric revolving tables in conventional settings usually use motors to drive the plates to achieve this purpose. However, when using the electric revolving tables, diners may need to manually stop the plates to separate meals or deal with other accidents. In this case, diners need to use a lot of force to resist the rotational force of the motor to stop the plates. This operation is very laborious and seriously affects the dining experience of diners. At the same time, in this process, the drive motor is forced to stop and trigger an overload. After long-term use, the drive motor is also prone to damage. Summary of the invention

[0003] To this end, the present invention provides a revolving dining table with a stall sensing function, which controls the driving connection between the revolving table top and the rotating drive device by adding an electromagnetic clutch between the revolving table top and the rotating drive device, and senses whether an artificial external force is controlling the revolving table top through a stall sensing unit. When it is sensed that the revolving table top is being controlled by an external force, the connection between the revolving table top and the rotating drive device can be disconnected through the electromagnetic clutch, so that the external force will not damage the motor, and the motor will not hinder the external force from controlling the revolving table top.

[0004] In order to achieve the above object, the present invention provides the following technical solution: a rotating dining table with a stop sensing function, comprising:

[0005] A supporting table body is used to install and support various components;

[0006] A rotating tabletop is arranged above the supporting table body, and a tabletop driving slot is arranged on the side of the rotating tabletop facing the supporting table body;

[0007] A rotary drive device, wherein the rotary drive device is fixedly connected to the supporting table body;

[0008] The electromagnetic clutch comprises a power end and an output end, the aforementioned rotation drive device is drivingly connected to the power end, the output end is fixedly provided with a torque transmission shaft, a plurality of torque transmission elastic members are provided between the torque transmission shaft and the aforementioned desktop drive slot, and the two ends of the torque transmission elastic member are respectively fixedly connected to the torque transmission shaft and the desktop drive slot;

[0009] The stall sensing unit comprises a matching sensing probe and a probe sensing strip, wherein the sensing probe is fixedly arranged on the side of the torque transmission shaft, and the probe sensing strip is fixedly arranged on the inner side wall of the desktop driving slot.

[0010] Furthermore, a limited rotation shaft is fixedly arranged at the middle position of the output end, a rotation bearing is arranged on the side of the rotating table top facing the supporting table body, and the rotating table top is rotationally connected to the limited rotation shaft through the rotation bearing.

[0011] Furthermore, the number of the torque transfer elastic members is preferably three, and the three torque transfer elastic members are arranged in a circular array on the outer side wall of the torque transfer shaft.

[0012] Furthermore, the lower end surface of the rotating table top is provided with a plurality of ball mounting grooves in a circular array, and supporting balls are rollingly arranged in the ball mounting grooves. A portion of the supporting balls exceeds the lower end surface of the rotating table top, and the lower end of the translating ball abuts against the upper end surface of the supporting table body.

[0013] Furthermore, a ball movement damping ring is provided on the upper end surface of the supporting table body, and the ball movement damping ring is made of soft material, and the lower end of the translation ball abuts against the ball movement damping ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the scheme of the present invention, the connection between the rotating table top and the rotating driving device is controlled by an electromagnetic clutch, and the triggering of the electromagnetic clutch relies on a stall sensing unit and a torque transmission elastic member. The stall sensing unit can sense the relative displacement between the rotating table top subjected to an external force and the output end of the electromagnetic clutch. When the displacement exceeds a preset value, the electromagnetic clutch will disconnect the connection between the rotating table top and the rotating driving device, so that the dining table can be free from the resistance of the rotating driving device and freely control the rotating table top, which is more convenient to operate.

[0016] 2. By arranging a plurality of supporting balls at the lower end of the rotating table top, effective support can be formed for the rotating table top, so that the rotating table top can operate stably after placing dishes. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] For example, see the attached Figure 1 , Attachment Figure 2 The present invention provides a rotating dining table with a stall sensing function, including a supporting table body 100 for installing and supporting various components, a rotating table top 200 is arranged above the supporting table body 100, and a table top driving slot 210 is arranged on the side of the rotating table top 200 facing the supporting table body 100, and the supporting table body 100 is located below the table top driving slot 210 and is fixedly connected to a rotating driving device 300, and the rotating driving device 300 generally adopts the form of a direct drive motor. In order to cooperate with the low-speed operation scenario of the dining table, a direct drive reduction motor or an accelerator structure can be adopted, and an electromagnetic clutch 400 and a stall sensing unit 600 are arranged between the rotating driving device 300 and the rotating table top 200. The electromagnetic clutch 400 is a prior art, as shown in the attached Figure 3As shown, it includes a power end 410 and an output end 420. The connection relationship between the power end 410 and the output end 420 can be controlled by the principle of electromagnetic induction, wherein the rotation drive device 300 is drivingly connected to the power end 410, and the electromagnetic clutch 400 can control whether the power output of the rotation drive device 300 is transmitted to the output end 420, that is, when the rotation drive device 300 continuously outputs power to drive the power end 410 to rotate continuously, the output end 420 can be controlled to rotate as needed, and the output end 420 is fixedly provided with a torque transmission shaft 430, and a plurality of torque transmission elastic members 500 are provided between the torque transmission shaft 430 and the aforementioned desktop drive slot 210, as shown in the attached Figure 5 As shown, the torque transmission elastic member 500 can be a spring, and the two ends of the torque transmission elastic member 500 are fixedly connected to the torque transmission shaft 430 and the desktop driving slot 210 respectively. In this embodiment, the number of the torque transmission elastic members 500 is preferably three, and the three torque transmission elastic members 500 are arranged in a circular array on the outer wall of the torque transmission shaft 430, and the stall sensing unit 600 includes a matching sensing probe 610 and a probe sensing strip 620. The sensing probe 610 is fixedly arranged on the side of the torque transmission shaft 430, and the probe sensing strip 620 is fixedly arranged on the inner wall of the desktop driving slot 210. The sensing probe 610 can be in the form of a Hall sensing element.

[0031] In a more optimized solution, a limited rotation shaft 440 is fixedly provided in the middle position of the output end 420, and a rotation bearing 220 is provided on the side of the rotating table top 200 facing the supporting table body 100. The rotating table top 200 is rotatably connected to the limited rotation shaft 440 through the rotation bearing 220. By utilizing the limited support of the limited rotation shaft 440 and cooperating with the rotation bearing 220, it is possible to ensure that the rotation center of the rotating table top 200 is always maintained at the initial position, and no eccentricity problem occurs.

[0032] In a more optimized solution, as shown in the attached Figure 4 As shown, the lower end surface of the rotating table top 200 is provided with a plurality of ball mounting grooves in a circular array, and support balls 230 are rollingly arranged in the ball mounting grooves. A portion of the support balls 230 extends beyond the lower end surface of the rotating table top 200, and the lower end of the translation ball abuts against the upper end surface of the supporting table body 100. At the same time, the upper end surface of the supporting table body 100 is provided with a ball movement damping ring 110, and the ball movement damping ring 110 is made of soft material. The lower end of the translation ball abuts against the ball movement damping ring 110, and the support balls 230 can form an effective support for the rotating table top 200, so that the rotating table top 200 can operate stably after the dishes are placed.

[0033] The working principle of this embodiment is as follows:

[0034] In this embodiment, the torque output by the rotation drive device 300 is relayed through the electromagnetic clutch 400 and then output to the rotating desktop 200. The electromagnetic clutch 400 can be used to control the connection between the rotation drive device 300 and the rotating desktop 200. When the rotation drive device 300 drives the rotating desktop 200 to rotate under a normal working environment, the power end 410 and the output end 420 of the electromagnetic clutch 400 are fixedly attracted. At this time, the rotation drive device 300 drives the power end 410 and the output end 420 to rotate together. When the output end 420 rotates, it will drive the rotating desktop 200 to rotate through the torque transmission elastic member 500. When the external force is strong, the rotation drive device 300 drives the power end 410 and the output end 420 to rotate together. When the rotating table top 200 is stopped (for example, when you want to stop picking up food), the rotating table top 200 will stop, while the output end 420 will continue to rotate. In this case, the rotating table top 200 will be subjected to external force and a relative displacement will occur between the output end 420. After a short period of relative displacement, the sensing probe 610 will move out of the sensing range of the probe sensing strip 620. At this time, it can be determined that the displacement exceeds the preset value. At this time, the electromagnetic clutch 400 will disconnect the connection between the power end 410 and the output end 420. At this time, the dining table can be free from the resistance of the rotating drive device 300, and the rotating table top 200 can be freely controlled, making the operation more convenient.
