Abstract

The invention provides a key module and an electronic scale. The key module comprises a touchpad, a conducting ring, a display film, a light source and a circuit board, wherein the touchpad is provided with a light transmission area, and the touchpad is in direct contact with the conducting ring; the conducting ring and the light source are electrically connected with the circuit board, and the display film is arranged between the light-transmitting area and the light source. When an operator touches the touchpad, the conducting ring transmits a touch signal to the circuit board after sensingthe touch signal, the circuit board controls the light source to be turned on, and light emitted by the light source forms a pattern in the light-transmitting area of the touchpad after passing through the display film, for example, the pattern can be a symbol, letter or character such as a switch electronic scale or reset. Due to the fact that the conducting ring is in direct contact with the touchpad, no isolation piece is arranged between the conducting ring and the touchpad, touch signals acting on the touchpad can be transmitted to the conducting piece more quickly and timely, and therefore the sensitivity of the touch key is improved, the response speed of the key module is high, and the user experience degree is high.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a button module and an electronic scale. Background technique [0002] Electronic products currently on the market, such as electronic scales, adopt the form of touch buttons. Most of the touch buttons on the electronic scale are screen-printed or etched function indicators on the display panel, and the touch button PCB board is pasted under the display panel. ; There are also LED lights under the display panel to illuminate the edge of the silk screen indicator on the panel, but the button indicator in the middle cannot be illuminated, and the light is uneven, and the light at some positions is dazzling; there are also injection molding on the display panel. The button indicator is provided with an LED light under the indicator, and the button spring is set on the outer ring. [0003] After research, it is found that the existing touch keys have the following disadvantages: ...
