Refills for active pens and active pens

Abstract

An active pen and a refill for the active pen. The refill comprises: a nib assembly (10); a pressure detection device (20), connected to the nib assembly (10) and used for sensing and determining pressure information from the nib assembly (10); and a supporting frame (30), used for accommodating the nib assembly (10) and the pressure detection device (20). A threaded hole (301) is formed in the supporting frame (30), and the supporting frame (30) is in threaded connection with the pressure detection device (20) through the threaded hole (301). The active pen and the refill structure for the active pen can ensure that the pressure detection device does not produce a relative slip when the active pen is used or falls, and provides 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
