Fig. 1 shows a cross-section of an electromagnetic pen 1. In some embodiments, the electromagnetic pen 1 includes a housing 10, a pen tip 11, a pen tip holder 12, and a pressure detection portion 13. In some embodiments, the housing 10 is formed of plastic, but the disclosure is not limited thereto. In some embodiments, pen tip 11 includes a first end 111 that protrudes from housing 10 and a second end 112 that is externally threaded. In some embodiments, nib holder 12 is disposed within housing 10 or is part of housing 10, i.e., housing 10 and nib holder 12 are integrally formed. In some embodiments, nib holder 12 includes a recess 121 with internal threads. In some embodiments, the internal threads of groove 121 mate with the external threads of second end 112 to secure nib 11 to nib mount 12. Fig. 1 shows an electromagnetic pen with a pen tip in an installed state. In some embodiments, first end 111 is provided with an opening 113 for receiving writing medium.
In some embodiments, the pressure detecting portion 13 is provided on the housing 10 and/or the pen tip holder 12. In some embodiments, when the electromagnetic pen 1 writes, the writing pressure is transmitted to the pressure detecting part 13, and whether writing is performed or not and the magnitude of the writing pressure are perceived.
In some embodiments, the writing medium includes any suitable writing medium such as a pencil head or an ink pen. In some embodiments, the nib 11 may be made of a wear-resistant, high temperature-resistant non-metallic material, such as polyacrylate, plastic, or the like. In some embodiments, the nib holder 12 may be made of a non-metallic material that is resistant to abrasion, high temperatures, such as polyacrylate, plastic, and the like.
The present disclosure facilitates replacement of writing medium 16 by mating the external threads of the nib with the internal threads of the nib holder, and rotating the nib to secure or detach. In addition, the damage to children when the pen tip is disassembled is avoided. In addition, the accident that the pen point flies out to hurt people in use can be avoided. In addition, through setting up pressure detection portion, the pressure that the electromagnetic pen can be perceived when writing, pressure detection portion shows when detecting pressure that the electromagnetic pen is writing this moment, can switch on corresponding circuit and acquire the orbit etc. that the electronic pen was written.
In some embodiments, first end 111 includes a land. In the present disclosure, the land portion refers to a portion of the outer peripheral surface having a plurality of ribs, with a land formed therebetween. In some embodiments, the land portion has a first width W1 in a direction perpendicular to a line connecting the first end portion 111 and the second end portion 112, the first width W1 gradually decreasing in a direction from the second end portion 112 toward the first end portion 111. By using a land, the user is helped to get better effort when rotating the pen tip, similar to screwing a screw.
As shown in fig. 3, in some embodiments, the first end 111 includes a detent 31 extending in a direction perpendicular to the line of the first end 111 and the second end 112.
As shown in FIG. 3, in some embodiments, pen tip 11 further includes a connection 114 connecting first end 111 and second end 112, connection 114 including a first portion 1141 adjacent first end 111 and a second portion 1142 adjacent first portion 1141. In some embodiments, the first portion 1141 has a second width W2 in a direction perpendicular to a line connecting the first end portion 111 and the second end portion 112, the second width W2 gradually increasing in a direction from the second end portion 112 toward the first end portion 111. As also shown in fig. 1, as the outer screw of second end 112 is engaged with the inner screw of nib holder 12, as nib 11 is slowly secured, opening 113 is also slowly compressed as W2 increases in a direction from second end 112 toward first end 111, and writing medium 16 may be more securely secured. While the writing medium is slowly and less firmly held in the opening as the nib 11 is slowly removed, i.e., slowly relaxed, the writing medium 16 may be individually replaced after the nib is removed.
In some embodiments, opening 113 extends into first portion 1141. In this manner, as W2 increases progressively in a direction from second end 112 toward first end 111, writing medium within opening 113 may be better secured due to the increased force of housing 10 against first portion 1141.
In some embodiments, second portion 1142 is disposed between first portion 1141 and second end 112, and a third width W3 of second portion 1142 is less than second width W2. As shown in fig. 5, in some embodiments, the magnetic ring 51 of the electromagnetic pen 1 is disposed around the second portion 1142. Since the third width W3 of the second portion 1142 is smaller than the second width W2, a space is left for the arrangement of the magnetic ring 51.
As shown in fig. 1, in some embodiments, the pressure detecting portion 13 includes a conductive portion 14, the conductive portion 14 being connected to the pen tip fixing base 12 and disposed on a side of the pen tip fixing base 12 remote from the second end portion 112. In some embodiments, the conductive portion 14 comprises an elastic rubber, in particular, a spherical conductive rubber.
In some embodiments, the pressure detecting portion 13 further includes a key circuit board 15 disposed opposite to the conductive portion 14, and a predetermined distance is provided between the key circuit board 15 and the conductive portion 14. In some embodiments, when writing media on, for example, a writing pad, the pressure of the writing media may be transferred to nib 11, nib 11 then transfers force to nib holder 12, nib holder 12 in turn transfers force to conductive portion 14, conductive portion 14 moves a predetermined distance into contact with the wires on key circuit board 15 and causes the key circuit board to conduct. In some embodiments, the resilient connection between nib holder 12 and housing 10 allows some relative movement when the perceived force of the writing medium is transferred to nib holder 12.
In some embodiments, the electromagnetic pen 1 further comprises an elastic member 17, the elastic member 17 being disposed within the housing 10 and connected with the nib holder 12. In some embodiments, the elastic member 17 may be a circular spring encircling the interior of the housing 10, and a section of the spring is fixed to the housing 10, and one end of the spring may be connected (e.g., fixedly connected) to the nib holder 12, so that when writing medium 16 is written, the generated pressure is conducted to the elastic member 17 through the nib holder 12, and the elastic member 17 contracts, and at this time, the conductive portion 14 contacts and contacts the key circuit board 15 to conduct a circuit. When the writing medium 16 stops writing, no pressure is generated, the elastic member 17 causes the nib holder 12 to return to the position before writing due to the elastic force, and the conductive portion 14 is disconnected from the key circuit board 15, and the circuit is broken.
It should be understood that the electromagnetic pen of the present disclosure is an active electromagnetic pen, and can write normally in paper, like a normal pen. In addition, the electromagnetic pen of the present disclosure may also include some components contained in conventional electromagnetic pens, such as coils, batteries, control circuits, etc., which are not described in detail herein for the sake of simplicity.
In some embodiments, an electronic device is also provided, including a writing pad and an electromagnetic pen as described above. As shown in fig. 6, in some embodiments, writing pad 61 has a recess 611 thereon that receives electromagnetic pen 1.
In some embodiments, the first end 111 includes a land portion having a first width W1 in a direction perpendicular to a line connecting the first end 111 and the second end 112, the first width W1 gradually decreasing in a direction from the second end 112 toward the first end 111. By using a land, the user is helped to get better effort when rotating the pen tip, similar to screwing a screw. In some embodiments, tablet 60 also includes a recess 612 that mates with the land. When the pen tip 11 of the electromagnetic pen 1 needs to be mounted or dismounted, the electromagnetic pen 1 can be inserted into the notch 612 on the handwriting board 60, and the mounting or dismounting of the pen tip 11 can be easily realized by rotating the electromagnetic pen 1 due to the matching of the notch 612 and the prismatic table part.
In some embodiments, as shown in fig. 3, the first end 111 includes a detent 31 extending in a direction perpendicular to the line of the first end 111 and the second end 112. In some embodiments, as shown in fig. 6, tablet 60 may further include a recess 612 that mates with first end 111, and a resilient tab (not shown) that mates with detent 31 may be provided in recess 612. Thus, by utilizing the elastic protruding portion and the positioning groove 31, no matter whether the shape of the first end portion 111 is the pyramid or the truncated cone, when the electromagnetic pen 1 is inserted into the notch 612, the elastic protruding portion can be retracted first, then ejected into the positioning groove 31, the electromagnetic pen 1 is fixed, and then the mounting or dismounting of the pen tip 11 can be easily achieved by rotating the electromagnetic pen 1.
