[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Figure 1 This is a structural diagram of a low-cost interactive light-based answering station of the utility model.

[0020] See Figure 1, the low-cost interactive lighting quiz table provided by the present utility model includes a base 1, a housing 2 and a panel 3. The base 1 is a rotational molding base, the housing 2 is a sheet metal housing, and the panel 3 is an acrylic panel. The inside of the sheet metal housing is hollow, and the sheet metal housing is fixed on the rotational molding base. The acrylic panel is provided with a quiz button 4 and an indicator light 5. The rotational molding base is provided with a control circuit board. The input end of the control circuit board is connected to the quiz button 4, and the output end of the control circuit board is connected to the indicator light 5.

[0021] Please continue to refer to Figure 2 , the low-cost interactive lighting quiz table provided by the present utility model, the control circuit board includes a main control MCU. The power supply end of the main control MCU is connected to a power supply voltage stabilization circuit. The input end of the main control MCU is connected to the quiz button 4 through a key input circuit. The output end of the main control MCU is connected to the indicator light 5 through an RGB output control circuit. The main control MCU is connected to a 2.4G wireless transceiver chip and a LORA wireless transceiver chip through an internal data bus. The main control MCU is connected to a computer host through the 2.4G wireless transceiver chip or the LORA wireless transceiver chip to receive a lighting adjustment signal. The distance of the 2.4G wireless transceiver circuit is relatively short, generally only about 20 - 50 meters, and its wall penetration ability is weak. Therefore, the main control circuit designed by the present utility model is compatible with two different wireless transmission methods. The transmission distance of LORA is very far, which can reach 300 - 500 meters, and its wall penetration ability is also good, and it can easily penetrate 3 - 5 layers of walls. Specifically, the main control MCU selects SH68F90 of Zhongying Electronics Co., Ltd., the LORA wireless transceiver chip selects SX1278 of SEMTECH Co., Ltd., and SX1268 of this company or the simplified version chip LLCC68 can also be selected. The 2.4G wireless transceiver chip selects SI24R1. The power supply voltage stabilization circuit part adopts the XC6206P332PR low-power voltage stabilization chip. The control circuit board uses the AT24C02 EEPROM chip as a parameter storage circuit. The RGB output control circuit uses MOS transistors, and the specific model is AO3401. The key input circuit selects a boat-shaped switch with a housing.

[0022] For the low-cost interactive lighting quiz table provided by the present utility model, the sheet metal housing is directly fixed on the rotational molding base through self-tapping screws. The rotational molding base is in a regular hexagon, square or circular shape. The surface of the rotational molding base forms a frosted semi-transparent layer. The rotational molding base has a hole in the middle for leading wires, and the wires can penetrate through it, which is used for power taking of the quiz answering control circuit and connecting the dedicated I / O port lighting control wire.

[0023] The low-cost interactive lighting quiz table provided by the present utility model comprehensively compares various materials such as wood, acrylic, aluminum profiles, and metal sheet metal, and finally the base formed by rotational molding is used as the base of the interactive quiz table. The advantage of rotational molding is that the mold cost is cheap, which is suitable for manufacturing large workbench products, such as Figure 3 the workbench 6 shown in the figure. However, due to the small order quantity of the interactive quiz table, directly customizing the mold is still too costly. The present utility model adopts an existing rotational molding process standard workbench product that meets the requirements, and designs a on-table quiz panel bracket that meets the functions of the interactive quiz table on the standard workbench, thereby forming a new type of lighting interactive quiz table with complete functions. Since the rotational molding base is a standard product with a large output, the cost is low. At the same time, the rotational molding product is light in weight, resistant to falling and not easy to break, which is suitable for long-distance transportation.

[0024] For the low-cost interactive lighting quiz table provided by the present utility model, the lights can be manually controlled by an infrared remote control. Single colors such as red, green, blue, purple, yellow, and cyan can be selected for long-term display, and display modes such as fast seven-color flashing and seven-color gradient can also be selected. It is directly controlled by the main control MCU and can be controlled to display light colors such as red, green, and blue. For example, when the quiz is successfully answered, the entire quiz table can light up green. When the quiz is fouled or the answer is incorrect, the entire quiz table automatically displays red. When in standby, blue, pink, yellow, or cyan lights can be selected for display, with various display methods such as constant lighting, flashing, and gradient. Due to the integrated design, the present utility model can receive the control signal of the computer at a long distance through a 2.4G wireless communication chip or a LORA wireless transceiver chip to form a fully functional wireless interactive lighting quiz answering system.

[0025] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be defined by the claims.
