AI Technical Summary

Technical Problem

Traditional styluses generate significant friction noise during prolonged use or rapid writing, and their rigid tip design may cause wear and tear on the screen, while soft materials affect writing accuracy and response speed.

Method used

The pen tip assembly design includes the pen tip body, shaft hole component, and pen refill component. The conductive needle contacts the screen. Through the cooperation of the pen refill sleeve, buffer groove, and damping spring, the impact force during writing is dispersed, reducing friction noise. The stability and protection of the assembly are ensured by detachable connecting blocks and limiting protrusions.

Benefits of technology

It achieves a low-noise writing experience, reduces screen wear, improves writing comfort and component lifespan, while enhancing the stability of electrical signal transmission and component compatibility.

Abstract

The utility model discloses a low-noise stylus nib assembly and a stylus. The stylus nib assembly comprises a stylus nib body, a shaft hole part formed in the stylus nib body and a refill part which is installed at the bottom end of the stylus nib body and made of copper surface gold-plated materials. The refill component comprises a refill sleeve installed at the bottom end of the pen point body, a buffer groove formed in the bottom end of the refill sleeve and a conductive needle arranged at the bottom end of the refill sleeve. A damping spring is arranged between the top end of the conductive needle and the inner side of the buffer groove; compared with traditional rigid connection, the touch screen has the advantages that impact force to a screen during writing is dispersed, sudden and strong friction is reduced, the writing process is smoother and mute, direct contact between the conductive needles and the screen or other writing surfaces is reduced, noise generated by friction is reduced, physical abrasion to the screen is relieved, and the touch screen is more attractive in appearance. Therefore, the service life of the screen and the touch pen can be prolonged.
