FIG. 3 is a schematic diagram illustrating the stylus as shown in FIG. 1, wherein the stylus is located at a threshold position after being inserted into a containing slot. In the following embodiments, the handheld electronic device may be a mobile phone, a smart phone or a PDA. Moreover, a portion of the handheld electronic device is not shown in FIG. 1, so as to clearly illustrate a position of a first magnetic member, and only a first position-limiting portion of a main body is illustrated in FIG. 3, so as to clearly illustrate relative positions among the stylus, the first position-limiting portion, the first magnetic member and a second magnetic member.
In addition, in other embodiments of the present invention, the handheld electronic device may also be a UMPC, a tablet PC, a pocket PC or other handheld electronic devices having a stylus.
Referring to FIG. 1, the handheld electronic device 10 includes a main body 100, a stylus 200 and a first magnetic member 300. The main body 100 has a containing slot 110. The stylus 200 is suitable for being inserted into the containing slot 110 and includes a stylus body 210 and a second magnetic member 220. Moreover, each of the first magnetic member 300 and the second magnetic member 220 can be a permanent magnet having an S pole and an N pole. The first magnetic member 300 is disposed at one side of the containing slot 110, wherein the S pole of the first magnetic member 300 faces towards the containing slot 110, and the N pole thereof faces oppositely. Moreover, the second magnetic member 220 is disposed to the stylus main body 210. When the stylus 200 is kept within the containing slot 110, the S pole of the second magnetic member 220 may be located adjacent to the first magnetic member 300, and the N pole of the second magnetic member 220 is located apart from the first magnetic member 300.
In addition, in another embodiment of the present invention, material of one of the first magnetic member 300 and the second magnetic member 220 may be diamagnetic material, paramagnetic material or ferromagnetic material. Moreover, if the material of one of the first magnetic member 300 and the second magnetic member 220 is the ferromagnetic material, the material of the ferromagnetic material includes at least one of iron, cobalt, nickel and samarium.
Referring to FIG. 2, in the present embodiment, the stylus body 210 includes a first part 210a and a second part 210b, and the second part 210b has an assembling slot 212 and a thread 214. Material of tip of the first part 210a may be plastic, and the material of the other part of the first part 210a may be aluminium. The material of the second part 210b may be plastic. Therefore, the stylus body 210 may present a metallic luster. In the present embodiment, the second magnetic member 220 is first disposed within the assembling slot 212 of the second part 210b, and then the second part 210b is assembled to the first part 210a via the thread 214 to form the stylus 200. Now, the other end of the first part 210a, which is located apart from the tip of the first part 210a leans against a position-limiting portion 216 of the second part 210a, so that joint of the first part 210a and the second part 210b has no obvious height difference in appearance after the first part 210a and the second part 210b are assembled. Moreover, in case the material of the first part 210a and the second part 210b is plastic, the first part 210a and the second part 210b may be integrally formed by injection molding so that the second magnetic member 220 may be directly embedded within the second part 210b. 
Referring to FIG. 1 again, when the stylus 200 is located outside the containing slot 110, the stylus 200 may be inserted into the containing slot 110 from an opening of the containing slot 110 along a first direction 400. Moreover, when the first magnetic member 300 and the second magnetic 220 is close enough to enable a magnetic attraction there between, the S pole of the first magnetic member 300 attracts the N pole of the second magnetic member 220 due to the magnetic force. Now, the stylus 200 may be moved towards the containing slot 110 due to the magnetic force, until the stylus 200 is totally contained within the containing slot 110. In other words, when the stylus 200 is inserted into the containing slot 110 for a predetermined distance, the stylus 200 may be sliding into the containing slot 110 automatically and fixed therein. Moreover, the S pole of the first magnetic member 300 may attract the N pole of the second magnetic member 220 due to the magnetic force, so as to keep the stylus 200 within the containing slot 110.
Based on the above embodiment, the stylus 200 may be kept within the containing slot 110 due to the magnetic force generated by the first magnetic member 300 and the second magnetic member 220, so as to substitute a lock-in structure of the conventional technique. Therefore, the present invention may solve the problem that the stylus 200 cannot be stably kept within the containing slot 110 due to worn out and malfunction of the conventional lock-in structure after a long time utilization. Moreover, as the stylus 200 may be sliding into the containing slot 110 automatically, utilization fun thereof is improved.
In addition, when the stylus 200 is totally sliding into the containing slot 110 due to the magnetic force, a head portion 230 at the end of the second part 210b may lean against a blocker 120a located at the opening of the containing slot 110, and meanwhile an impact sound is occurred. Now, according to the impact sound, the stylus 200 can be judged to be located at a threshold position after being inserted into the containing slot 110.
Next, referring to FIG. 1 and FIG. 3, to further guarantee that the stylus may be stably locked in the main body 100, the main body 100 may further have a first position-limiting portion 130, and the stylus body 210 may further have a second position-limiting portion 240. The first position-limiting portion 130 may be a protrusion located within the containing slot 110, and the second position-limiting portion 240 may be a groove formed at side surface of the stylus body 210. As shown in FIG. 3, when the stylus 200 is totally contained within the containing slot 110, the first position-limiting portion 130 may be interfered with the second position-limiting portion 240, so that the stylus 200 may be more stably kept within the containing slot 110.
It should be noted that in the embodiment of FIG. 3, when the stylus 200 is totally contained within the containing slot 110, the first magnetic member 300 may be misaligned with the second magnetic member 220. Namely, position of the first magnetic member 300 does not totally correspond to the position of the second magnetic member 220. Now, center of the first magnetic member 300 may correspond to a position between center of the second magnetic member 220 and the tip of the stylus 200. Therefore, the S pole of the first magnetic member 300 and the N pole of the second magnetic member 220 may maintain an attractive state continuously, such that the stylus 200 may be stably kept within the containing slot 110.
FIG. 4 is a schematic diagram illustrating the stylus as shown in FIG. 1, wherein the stylus is located at a threshold position after being inserted into a containing slot according to another embodiment of the present invention. It should be noted that only the first position-limiting portion of the main body and the blocker located at the end of the containing slot are illustrated, so as to clearly illustrate relative positions among the stylus, the first position-limiting portion, the blocker, the first magnetic member and the second magnetic member.
Referring to FIG. 4, in the present embodiment, the main body (not shown in FIG. 4) further has another blocker 120b. The blocker 120b may be disposed at the end of the containing slot (not shown in FIG. 4), and a shape thereof approximately corresponds to the shape of the tip of the stylus 200. When the stylus 200 is totally contained within the containing slot, the tip of the stylus 200 leans against the blocker 120b, so as to limit a threshold position of the stylus 200 after the stylus being inserted into the containing slot. Similarly, when the tip of the stylus 200 leans against the blocker 120b, an impact sound is occurred, and according to the impact sound, the stylus 200 can be judged to be located at a threshold position after being inserted into the containing slot.
In addition, the S pole of the first magnetic member 300 may attract the N pole of the second magnetic member 220 due to the magnetic force there between, so as to keep the stylus 200 within the containing slot 110. Therefore, the present invention may solve the problem that the stylus 200 cannot be stably kept within the containing slot due to worn out and malfunction of the conventional lock-in structure after a long time utilization. Moreover, the stylus 200 may further be stably kept within the containing slot 110 via interference between the first position-limiting portion 130 and the second position-limiting portion 240.
In summary, in the present invention, the stylus is kept within the containing slot via the magnetic force generated by the first magnetic member and the second magnetic member, so as to substitute the lock-in structure of the conventional technique. Therefore, the present invention may solve the problem that the stylus cannot be stably kept within the containing slot due to worn out and malfunction of the conventional lock-in structure after a long time utilization.
Moreover, when the first magnetic member and the second magnetic member are close enough to generate the magnetic force there between, the first magnetic member may attract the second magnetic member via the magnetic force, so that the stylus may move towards the containing slot automatically until the stylus is totally contained within the containing slot. Now, according to the impact sound generated when the stylus leans against the blocker, the stylus can be judged to be located at the threshold position after being inserted into the containing slot.
Moreover, when the stylus is totally contained within the containing slot, the position of the first magnetic member may be misaligned with the position of the second magnetic member, such that the first magnetic member and the second magnetic member may maintain the attractive state continuously, so as to stably keep the stylus within the containing slot.
In addition, in the present invention, not only the blocker may be applied for limiting the threshold position of the stylus after the stylus being inserted into the containing slot, but also the stylus may further be stably kept within the containing slot via interference between the first position-limiting portion and the second position-limiting portion.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
