Technical Field

[0001] This utility model relates to the technical field of dining table utensils, specifically to a driving mechanism for a dining table turntable. Background Technology

[0002] In large dining settings, a turntable is typically installed on the table. Traditional turntables require manual control to rotate so that diners can select different dishes. To make dining more convenient, technicians have devised a system that allows the dishes on the turntable to rotate automatically.

[0003] Existing dining table turntables typically use AC motors to drive the turntable, resulting in a constant turntable speed after factory settings, which users cannot adjust according to their actual needs during use.

[0004] Therefore, further improvements are needed. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1-5The drive mechanism of this dining table turntable includes a base 1 and a sliding ring 2. A DC motor 3 and an electronic control board 4 that converts AC power to DC power are fixedly connected to the base 1. The DC motor 3 is driven by the sliding ring 2, allowing the base 1 to rotate relative to the sliding ring 2. The electronic control board 4 is electrically connected to the DC motor 3. The electronic control board 4 can adjust the speed of the DC motor 3 by adjusting the output voltage of the DC motor 3, so that the speed of the dining table turntable can be changed in real time according to the user's needs, making the product adaptable to more different application scenarios. Moreover, the electronic control board 4 can be directly connected to an external AC power source, making the product more convenient for users.

[0024] The electronic control board 4 can convert AC power into DC power and control the output DC voltage by setting rectifier components and potentiometer components. The specific structure and working principle of the rectifier components and potentiometer components in the electronic control board 4 are existing technologies and can be understood by those skilled in the art.

[0025] Furthermore, the DC motor 3 is connected to a motor mounting plate 31, which has a plurality of motor mounting ears 311. The base 1 has motor mounting studs 11 corresponding to the motor mounting ears 311. The motor mounting studs 11 and the motor mounting ears 311 are fixed together by a screw device, thereby improving the installation accuracy and connection strength between the DC motor 3 and the base 1.

[0026] Furthermore, a relay 5 is provided between the control board 4 and the DC motor 3. The relay 5 is fixedly installed on the base 1. The relay 5 is electrically connected to the control board 4 and the DC motor 3 respectively. The relay 5 is arranged adjacent to the control board 4 and the DC motor 3, which facilitates the wiring layout between the control board 4, the relay 5 and the DC motor 3.

[0027] Relay 5 can switch the positive and negative poles of the output voltage of DC motor 3, thereby controlling the direction of DC motor 3. This allows the turntable to switch between forward and reverse rotation at will through a relatively simple transmission mechanism, further improving the product's adaptability.

[0028] Furthermore, the base 1 is provided with a positioning post 12 and a mounting screw hole 13 that can be installed and cooperate with the AC motor. The relay 5 is provided with a positioning insertion hole 51 and a plate mounting hole 52 corresponding to the positioning post 12 and the mounting screw hole 13. The positioning post 12 is inserted and cooperated with the positioning insertion hole 51, and the plate mounting hole 52 and the mounting screw hole 13 are fixed by a screw device. The manufacturer can use the base 1 model that is originally used with AC motors for production and processing. It only needs to open the mounting structure corresponding to the DC motor 3 on the basis of the base 1 model that is originally used with AC motors. The manufacturer does not need to open a new base 1 mold, which reduces the product processing cost.

[0029] Furthermore, a first cooling fan 61 is installed on the base 1, and a first baffle plate 71 is provided on the base 1 at the outer position corresponding to the first cooling fan 61. The first end of the first baffle plate 71 is connected to the side wall of the base 1, and the end of the first baffle plate 71 is arranged adjacent to the electronic control board 4. The first baffle plate 71 forms a first heat dissipation channel 81 on the side facing the first cooling fan 61. The electronic control board 4 and the first cooling fan 61 are respectively arranged in the first heat dissipation channel 81. The airflow generated by the first cooling fan 61 can flow more concentratedly in the first heat dissipation channel 81, thereby improving the heat dissipation effect on the electronic control board 4.

[0030] Furthermore, the electronic control board 4 is provided with heat dissipation fins 41 on the side corresponding to the first heat dissipation fan 61, which can further improve the heat dissipation effect of the electronic control board 4.

[0031] Furthermore, the base 1 is provided with a heating element 9 and a second cooling fan 62. The base 1 has a second baffle 72 on the outer side corresponding to the second cooling fan 62. The side of the second baffle 72 facing the second cooling fan 62 forms a second heat dissipation channel 82. The heating element 9 and the second cooling fan 62 are respectively arranged in the second heat dissipation channel 82. The airflow generated by the second cooling fan 62 can flow more concentratedly in the second heat dissipation channel 82, thereby improving the heat dissipation effect on the heating element 9.

[0032] Furthermore, the first baffle plate 71 passes through the position between the heating component 9, the first cooling fan 61, and the electronic control board 4, which can reduce the impact of the heat generated by the heating component 9 on the electronic control board 4, and at the same time reduce the chance of airflow interference between the first air duct and the second air duct.

[0033] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
