Touch key assembly and method for producing touch key assembly

Abstract

The invention provides a touch key assembly and a method for producing the touch key assembly. The touch key assembly comprises a panel, a supporting plate, a sensor and a PCB, wherein the supporting plate is located behind the panel and is installed on the panel, the rear surface of the panel corresponds to the front surface of the supporting plate, the sensor is located behind the supporting plate and is installed on the supporting plate, the front surface of the sensor corresponds to the rear surface of the supporting plate, the PCB is located behind the sensor, and the PCB and the sensor are installed together. The touch key assembly is simple in structure and convenient to assemble, the manufacturing difficulty of the panel is converted into the manufacturing difficulty of the supporting plate and the sensor through the arrangement of the supporting plate, the manufacturing difficulty of the panel is effectively lowered, the manufacturing difficulty of the panel, the manufacturing difficulty of the supporting plate and the manufacturing difficulty of the sensor are all quite low, in this way, the purpose of reducing the production cost of the touch key assembly is achieved, and the design concept of product optimization of enterprises is better reflected.

Description

technical field [0001] The invention relates to the field of home appliances, and more specifically, to a touch key assembly and a production method of the touch key assembly. Background technique [0002] At present, most of the household appliances with touch function on the market are made of plastic or glass and other materials with high insulating medium. There is a disadvantage of gaps between type buttons, but its inherent working principle determines that its panel cannot be made of metal materials (because the sensor and panel are directly assembled, there is a possibility of electric connection, so electric shock accidents may occur), and the product is in In practical applications, due to the influence of temperature, humidity and materials, there are unreliable buttons. [0003] However, metal panels have the advantages of elegant appearance, no fear of water and harmful gases, and no material restrictions, which can overcome the problems in the above-mentioned ...

AI Technical Summary

Problems solved by technology

[0006] 1. The existing sensors are required to be closely attached to the panel, and there are problems such as difficult positioning, difficult lamination process, complicated panel surface treatment process, and inconvenient after-sales disassembly and maintenance, which violates the concept of enterprise product optimization;

[0007] 2. The existing panels have high requirements on materials and sensors, but their versatility and reliability are poor
