FIG. 3 is a schematic diagram of the electronic device and the pen in a suction state according to the present invention. Fig. 4 is a schematic view partially showing the arrangement of magnets and the distribution of magnetic fields of the stylus pen according to the present invention.
Referring to fig. 2, the stylus pen 2 according to the present invention is provided with a magnetic force adsorption section disposed along a length direction of the stylus pen 2, and specifically, the magnetic force adsorption section of the stylus pen 2 may include: a receiving groove 21 extending in a longitudinal direction of the pen 2; and a plurality of magnets 22 disposed in the accommodating groove 21 and spaced apart from each other by a predetermined interval. Wherein the magnets 22 may be arranged such that like poles of two adjacent magnets 22 are opposite to each other. Further, the plurality of magnets 22 may have different specifications such as size, type, and the like. According to the present invention, by arranging the magnets in such a manner as described above, it is possible to provide more lines of magnetic force perpendicular to the longitudinal direction of the writing pen 2 in the case where the magnetic force of a single magnet and the space of the accommodation groove (the total space where the magnets are arranged) are the same, thereby maximizing the total magnetic attraction force to the magnetic material (e.g., magnetic metal 31 as described below) of all the magnets in the accommodation groove 21, the specific distribution of the lines of magnetic force being as shown in fig. 4, the attraction force of the writing pen 2 can be increased in the writing pen 2 by arranging the magnets in such a manner as described above as compared to the related art as shown in fig. 1.
According to an example of the present invention, the receiving groove 21 may include a plurality of cavity grooves respectively receiving the plurality of magnets 22, and the plurality of cavity grooves may be separated from each other by a predetermined interval. Specifically, when the receiving groove 21 includes the first, second, third and fourth cavity grooves 211, 212, 213 and 214, the magnet 22 may be disposed between the first and second cavity grooves 211 and 212 in such a manner that the S and S poles of the magnet 22 face each other, between the second and third cavity grooves 212 and 213 in such a manner that the N and N poles of the magnet 22 face each other, and between the third and fourth cavity grooves 213 and 214 in such a manner that the S and S poles of the magnet 22 face each other, that is, four magnets 22 are arranged in the manner of N, S, S, N, N, S, S, N, as shown in fig. 2 and 4. However, the arrangement of the four magnets 22 is not limited to this, and may be arranged in the manner of S, N, N, S, S, N, N, S.
Further, the housing groove 21 may be a single long groove, and the plurality of magnets 22 may be sequentially disposed in the single long groove in such a manner that like poles of two adjacent magnets are opposed to each other.
Further, when the length of each magnet is defined as L and the interval between adjacent magnets 22 is defined as P, the plurality of magnets may be arranged in such a manner as to satisfy the relation 1: p is 0.1L to 0.2L. Preferably, P ═ 0.6L-0.7L. In addition, the plurality of magnets may be arranged at the same interval or at different intervals according to actual design requirements. Thus, in the case where the handwriting pen has the same-length accommodation grooves, the magnet 22 according to the present invention can not only reduce the total number of magnets to be arranged and reduce the weight of the handwriting pen 2, but also enhance the total magnetic force of the magnet in the accommodation groove 21, thereby greatly enhancing the attractive force of the handwriting pen 2, by the above-described arrangement in which the magnets are arranged such that the like poles oppose each other, as compared to the arrangement shown in fig. 1 according to the related art. Therefore, the stylus pen 2 according to the present invention can be firmly attached to the side of the electronic device where the magnetic metal is provided.
Further, the number of magnets 22 according to the present invention is not limited to the number shown in the drawings, but the number of magnets may be increased or decreased according to actual needs.
Further, the magnet 22 of the stylus pen 2 according to the present invention may have a sectional shape of a circle, a quadrangle, a hexagon, etc., and preferably, the magnet 22 may have a sectional shape of a circle, that is, the magnet may be a cylindrical magnet. However, the present invention is not limited thereto, and the shape of the magnet may be arbitrarily changed according to actual needs.
According to another example of the present invention, an electronic device 3 may also be provided. The electronic device 3 includes the stylus pen 2 as described above and a magnetic metal 31 provided at a side portion of the electronic device 3. When the stylus pen 2 is attached to the electronic device 3, at least a portion of the magnetic metal 31 is always opposite to the magnetic force attaching section of the stylus pen 2. The magnetic metal 31 may be formed on a part of or the entire side bezel of the electronic device 3, or may be a part of the housing of the electronic device 3, or may be an additionally provided magnetic metal strip or magnetic metal sheet. The magnetic metal 31 may be disposed outside or inside the side frame of the electronic device 3 or disposed in the side frame of the electronic device 3 according to actual design requirements. The magnetic metal 31 may be, for example, SUS 430 or the like, but is not limited thereto as long as the metal having a magnetic function is applicable to the present invention.
In addition, the magnetic metal 31 may be provided only at a specific position of the electronic device 3, so that the stylus pen 2 is attached to the specific position of the electronic device 3. In addition, for the convenience of user operation, the magnetic metal 31 may be disposed at a plurality of positions on the side of the electronic device 3 so that the stylus pen 2 can be attracted to a plurality of positions or any position on the side of the electronic device 3 by magnetic attraction. Specifically, the magnetic metal 31 may be disposed at a corresponding position of the electronic device 3 according to actual design requirements, so that the stylus pen 2 is firmly attached to any position of the electronic device 3 at any angle and in any direction by the magnetic attraction between the magnetic metal 31 and the magnet 22.
In addition, the electronic device 3 may further include at least one hall sensor 32 disposed at a side portion of the electronic device 3 such that the magnetic force adsorption section of the stylus pen 2 is opposite to at least a portion of the magnetic metal 31 and the at least one hall sensor 32 when the stylus pen 2 is adsorbed on the electronic device 3. The hall sensor 32 may be disposed spaced apart from the magnetic metal 31, may be disposed on the surface of the magnetic metal 31, or may be embedded in the magnetic metal 31.
The hall sensor 32 may be used primarily to sense whether the stylus 2 is attached to the electronic device 3. Specifically, the hall sensor 32 installed in the electronic device 3 may transmit its sensed result to the controller in the electronic device 3 when sensing a change in the magnetic field of the stylus pen 2, and the controller may perform a corresponding function in response to the sensed result of the hall sensor 32. For example, when the hall sensor 32 senses that the magnetic field intensity of the stylus pen 2 is less than a first predetermined value, the sensing result may be transmitted to the controller of the electronic device 3, and the controller may determine that the stylus pen 2 is separated from the electronic device 3 and control the electronic device 3 to perform the first function. When the hall sensor 32 senses that the magnetic field intensity of the stylus pen 2 is greater than a second predetermined value, the sensing result may be transmitted to the controller of the electronic device 3, and the controller may determine that the stylus pen 2 is attached to the electronic device 3 and control the electronic device 3 to perform a second function. For example, the controller may control the electronic device 3 to perform a function of lighting the screen when the controller determines that the stylus 2 is separated from the electronic device 3, and may control the electronic device 3 to perform a function of turning off the screen when the controller determines that the stylus 2 is attached to the electronic device 3. The specific forms of the first function and the second function are not limited thereto, and various changes may be made according to actual needs. For example, the first function may be to light up the screen and turn on the memo function or notepad function, and the second function may be to turn off the screen and turn off the memo function or notepad function. Further, the first predetermined value and the second predetermined value may not be the same.
Further, the hall sensor 32 may be provided in plurality so that the electronic device 3 can each sense the suction or removal of the stylus pen 2 when the stylus pen 2 is placed at a different position of the electronic device 3. Preferably, when a plurality of hall sensors 32 are provided, the distance between two adjacent hall sensors is less than the total length of the magnetically attracting section of the stylus pen 2.
Specifically, the number of the hall sensors 32 may be set according to the placement position of the stylus pen 2 or the length of the stylus pen 2, as long as the magnetic force adsorption section of the stylus pen 2 corresponds to at least a portion of the magnetic metal 31 and at least one hall sensor 32 when the stylus pen 2 is adsorbed on the electronic device 3. For example, when the stylus pen 2 has a wide coverage of the magnetic field due to its long length, the number of the hall sensors 32 may be only one as long as the magnetic field signal of the stylus pen 2 can be received. Similarly, when the coverage of the magnetic field of the stylus pen 2 is small due to the short length, the number of the hall sensors 32 may be increased as appropriate, for example, 2 or more, so that the magnetic field signal of the stylus pen 2 can be received no matter where the stylus pen 2 is attached to the electronic device 3.
In order to enable the electronic device 3 to sense the magnetic field change of the stylus pen 2 no matter at any position of the side of the electronic device 3 where the magnetic metal 31 and the hall sensor 32 are disposed, the arrangement manner of the hall sensor 32 and the length and arrangement manner of the magnetic force adsorption section in the stylus pen 2 may satisfy the following arrangement relation 2: a < C, B < D, where a includes a1 and a2, a1 is a distance from the hall sensor located at the uppermost side to the uppermost end of the electronic device 3 on the one side, a2 is a distance from the hall sensor located at the lowermost side to the lowermost end of the electronic device 3 on the one side, B is a distance between two adjacent hall sensors 32, B may include B1, B2 … … Bn-1, n is the number of hall sensors 32, C includes C1 and C2, C1 is a distance from the first end of the magnetic force adsorption section to the farther end of the stylus pen 2, C2 is a distance from the second end of the magnetic force adsorption section to the farther other end of the stylus pen 2, and D is a distance from the first end to the second end of the magnetic force adsorption section, that is, a length of the magnetic force adsorption section. Among them, specific sizes of a1 and a2, and C1 and C2 are not particularly limited as long as the above relational expression 2 is satisfied.
Fig. 3 shows an arrangement manner in which the electronic device 3 is provided with the magnetic metal 31 and the two hall sensors 32, taking the electronic device 3 as a PAD as an example. Specifically, as shown in fig. 3, when the stylus pen 2 is attached to the right side of the electronic device 3 with the pen tip facing up, the magnetic metal 31 and the at least one hall sensor 32 located at the electronic device 3 may be disposed at the right side of the electronic device 3 to correspond to the magnetic force attaching section of the stylus pen 2 in a state where one end of the stylus pen 2 is flush with one end of the electronic device 3, so as to ensure that the stylus pen 2 is firmly attached and the electronic device 3 can sense the stylus pen 2 through the hall sensor 32. When the hall sensor 32 includes the first hall sensor 321 and the second hall sensor 322, a1 may be a distance from the first hall sensor 321 to an uppermost end of the electronic device 3, a2 may be a distance from the second hall sensor 322 to a lowermost end of the electronic device 3, B may be a distance between the first hall sensor 321 and the second hall sensor 322, C1 may be a distance from a first end (an end closest to a pen tip of the stylus 2) of the magnetic force adsorption section to a farther end (an end opposite to the pen tip of the stylus 2) of the stylus 2, C2 may be a distance from a second end (the farthest end from the pen tip of the stylus 2) of the magnetic force adsorption section to the farther other end (the end of the stylus 2 having the pen tip), D may be a distance from the first end to the second end of the magnetic force adsorption section, that is, a length of the magnetic force adsorption section, and satisfies relation 2: a < C, B < D. Among them, the relationship between a1 and a2, C1 and C2 is not particularly limited as long as the above relational expression 2 is satisfied.
In addition, the 3 power supply of the electronic device may provide power to the hall sensor 32 to maintain the operation of the hall sensor 32.
According to the present invention, in the case where the stylus pen 2 has the magnet disposed as above, the suction position and the suction direction of the stylus pen 2 at the side of the electronic device 3 where the magnetic metal is disposed may not be limited, and the stylus pen 2 may have a strong suction force, for example, the stylus pen 2 may be firmly sucked at the side of the electronic device 3 where the magnetic metal is disposed rotatably 180 °.
The electronic device 3 may be at least one of a mobile phone, a tablet computer, a palm computer, etc., but the present invention is not limited thereto, and any device that requires information input by a stylus may be applied to the present invention.
