Abstract
Description
Technical Field

[0002] A magnetic-capacitive integrated screen refers to a display device that combines magnetic attraction technology and capacitive technology. This technology can provide a more convenient user interaction experience. The electromagnetic pen determines its position by inducing an electromagnetic field. The electromagnetic pen generally includes a shell and a refill fixed in the shell, a refill mounting part, and an electromagnetic resonance circuit. The tip of the refill becomes worn after a period of use and needs to be replaced.
[0003] The pen refill in the prior art is usually a solid structure, and the fixation with the mounting hole relies on the extrusion deformation of the elastic material of the pen refill body. The diameter of the pen refill body is larger than the diameter of the mounting hole of the pen refill mounting piece, so the pen refill is firmly fixed, but it is difficult to pull out and replace and install a new pen refill; when the diameter of the pen refill body is smaller than the diameter of the mounting hole of the pen refill mounting piece, it is easy to replace and install a new pen refill, but the pen refill is easy to fall off, which requires the diameter of the pen refill body to be equal to the diameter of the mounting hole of the pen refill mounting piece, which undoubtedly increases the processing accuracy and cost.

[0018] (III) Beneficial effects
[0019] Compared with the prior art, the utility model provides an electromagnetic pen for a magnetic-capacitive integrated screen, which has the following beneficial effects:
[0020] (1) The electromagnetic pen used for the magnetic capacitance integrated screen pulls the front control surface forward, and then the front control surface drives the front control rod to start moving forward. After the transmission, the limit engaging state of the front limit mechanism is released. At the same time, the rear control surface is pulled backward, and then according to the above, the limit engaging state of the rear engaging mechanism is also released. Then, the pen core can be taken out from the inside of the pen core installation groove for replacement by moving it downward. When replacing, the pen core can be limited and fixed according to the above method. In this way, the pen core can be replaced simply, conveniently and firmly, thereby improving the replacement efficiency of the pen core, while also reducing the processing accuracy of the electromagnetic pen, thereby reducing the processing cost.
[0021] (2) The electromagnetic pen for the magnetic-capacitive integrated screen has a method of releasing the limit state of the limit mechanism only by pulling the control surface, because the accidental touch that occurs during the use of the electromagnetic pen is basically caused by pressing the electromagnetic pen shell, so that the limit mechanism will not be released in the event of an accidental touch during the use of the electromagnetic pen, thereby improving the stability of the electromagnetic pen limit mechanism during use.
