Pen core for active pen and active pen

Abstract

The application provides a pen core for an active pen and an active pen.The pen core for the active pen of the application comprises a pen point assembly; a pressure detection device which is connected with the pen point and is used for sensing and determining the pressure information from the pen point assembly; and a support frame which is used for containing the pen point assembly and the pressure detection device; wherein the support frame is provided with a threaded hole therein; the support frame is connected with the pressure detection device through the threaded hole in a threaded mode. According to the active pen and the pen core struction for the active pen of the application, the pressure detection device will not slide during the usage of the active pen or falling and has good stability.

Description

technical field [0001] The present application relates to the field of touch technology, in particular to an active pen and a refill for the active pen. Background technique [0002] With the development of touch technology, more and more mobile terminals use touch to perform human-computer interaction. The active pen is a common tool used in human-computer interaction. The current working principle of the active pen is based on the fact that when writing, the screen of the electronic device will transmit a certain pressure to the refill, and the pressure detection device inside the refill of the active pen will After receiving the pressure and processing the received pressure signal, it is sent to the screen of the electronic device through the conductive component and the pen core, and then coupled with the capacitance of the screen end, so that the display of the electronic device, that is, the touch screen, presents the written image. content.

Problems solved by technology

[0005] 1. The support frame 407 and the nib guide sleeve 411 are connected by buckles, so that there is a gap between them, causing the nib guide sleeve 411 and the nib 401 to be unstable and shake to a certain extent;

[0006] 2. The main board 403 of the pressure detection device communicates with the pen tube 410 through the spring 409 welded on the main board. However, due to the uncertainty of the bending degree of the spring, poor contact occurs during use or when the active pen falls , reducing the reliability of the active pen;

[0007] 3. The support frame 407 and the main board 403 carrying the pressure detection device are fixed by buckles, so that when the pen tip is under pressure, relative sliding occurs between the pressure detection device and the support frame 407, so that the pressure on the pen tip of the active pen is unstable ;

[0008] 4. There is a gap between the tail of the nib holder 411 and the pressure sensor 402 of the pressure detection device, so that the nib will retract inward (that is, toward the direction of the pressure detection device) when writing, resulting in a bad writing experience
