A touch pen with a pen point assembly and a pen cap moving synchronously

Abstract

The invention discloses a touch pen with a pen point assembly and a pen cap moving synchronously. The touch pen comprises a pen holder, the pen point assembly, a drive circuit unit, the pen cap and anelastic assembly. The pen point assembly is electrically connected with the drive circuit unit; the pen cap is combined with the pen point assembly and enables one end of the pen point assembly to beexposed, and an exposed distance is reserved between the top edge of the end and the end edge of the pen cap. When the pen point assembly is pressed; the end part of the pen point assembly and the pen cap can synchronously move from an initial position; the elastic assembly is contracted inwards and compressed in the direction of the pen holder under the condition that the exposure distance is not changed; when the elastic assembly recovers elasticity to release the pen point assembly, the end part of the pen point assembly and the pen cap return to the initial position together, loss or weakening of the signal strength of the touch pen is avoided, and then the signal strength of the touch pen is maintained.

Description

technical field [0001] The invention relates to a stylus, in particular to a stylus with synchronous movement of a pen tip assembly and a pen cap. Background technique [0002] Among consumer electronic products on the market, electronic products with touch panels are becoming more and more common, especially a capacitive touch panel, which uses the conductive and electrostatic properties of the human body to achieve touch control. Purpose. When the user directly touches the touch area of ​​the touch panel with a finger, the capacitance value of the contact position will change, and the touch panel can determine the position selected by the user according to the changed position of the capacitance value, so as to achieve the touch control effect. Purpose. [0003] As far as the existing active capacitive stylus touch panel is concerned, it is widely used due to its advantages of convenient writing, pen tip pressure-sensitivity and high sensitivity. Such as Figure 8 As sh...

Problems solved by technology

However, when the active capacitive stylus is in use, the nib B that shrinks and moves in the direction of the control unit D will be close to the pen cap A, causing the distance between the protective cover and the pen cap A to be closer and closer, causing a gap between the pen nib B and the pen cap A. Circuit feedback or feedback (signal feed-back), thereby weakening the strength of the sending and receiving signal (loss / Loss), and even causing inability to sense in severe cases

In addition, the existing active capacitive stylus has many components, and tolerances will accumulate during assembly, resulting in time-consuming, labor-intensive and difficult assembly problems
