In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the described specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0048] In some embodiments, the stylus comprises a housing, a placing piece 500 and a magnet group. The housing has a storage cavity. The shape of the housing can be cylindrical, hexagonal prism, etc. The housing can be held by the user. In addition to the placing piece 500 and the magnet group, the storage cavity can also store electronic components. The placing piece 500 has a placing groove 510, and the placing piece 500 is arranged in the storage cavity. The placing piece 500 can be used to place the magnet group. Specifically, a support can be placed in the storage cavity, and the placing piece 500 can be connected with the support. The magnet group is arranged in the placing groove 510, and the magnet group comprises at least three magnets. Specifically, by arranging the magnet group in the placing piece 500, and the magnet group comprises at least three magnets, so that the arrangement of the at least three magnets can make the stylus have a larger magnetic attraction force, so that the stylus can be adsorbed on the electronic device, which can effectively ensure that the stylus and the electronic device are accurately and stably positioned when the stylus is charged by the electronic device, and effectively improve the charging efficiency. Specifically, the stylus can have a larger magnetic attraction force.

[0049] Further, when the magnet group comprises at least three magnets, there are many cases of the arrangement mode among the three magnets, and one of the cases is introduced as follows. Please refer to Figures 1 to 3In some embodiments, the placement slot 510 includes a first slot wall 511, an opposing second slot wall 512 and a third slot wall 513, and opposing fourth slot walls 514 and 515. The second slot wall 512, the third slot wall 513, the fourth slot wall 514, and the fifth slot wall 515 surround and connect to the first slot wall 511. That is, the placement slot 510 can be square in shape. The magnets in this application can also be square in shape. The magnet assembly includes a first magnet 100, a second magnet 200, and a third magnet 300. The first magnet 100 includes an S pole and a N pole, the second magnet 200 includes an S pole and a N pole, and the third magnet 300 includes an S pole and a N pole. The third magnet 300 is disposed between the first magnet 100 and the second magnet 200. The two magnetic poles of the first magnet 100 are respectively distributed along the first direction, the two magnetic poles of the second magnet 200 are respectively distributed along the first direction, and the two magnetic poles of the third magnet 300 are distributed along the second direction. The two magnetic poles of the third magnet 300 face the first magnet 100 and the second magnet 200, respectively. Specifically, the two magnetic poles of the third magnet 300 facing the first magnet 100 and the second magnet 200, respectively, can be that the north pole of the third magnet 300 faces the first magnet 100, and the south pole of the third magnet 300 faces the second magnet 200. The magnetic pole of the first magnet 100 facing the first slot wall 511 is opposite to the magnetic pole of the second magnet 200 facing the first slot wall 511. Specifically, the magnetic pole of the first magnet 100 facing the first slot wall 511 is opposite to the magnetic pole of the second magnet 200 facing the first slot wall 511, and the magnetic pole of the first magnet 100 facing the first slot wall 511 is opposite to the magnetic pole of the second magnet 200 facing the first slot wall 511. The first direction and the second direction are perpendicular. The first direction can be a vertical direction, and the second direction can be a horizontal direction. Specifically, by arranging the first magnet 100, the second magnet 200, and the third magnet 300 as described above, the centering of the magnet group can be improved, so that the stylus pen can be accurately adsorbed at a specific position, instead of the stylus pen being accurately adsorbed at a specific position and then the magnet group deviating from the position after the stylus pen is adsorbed.

[0050] It should be noted that the orientation of the magnetic poles of the first magnet 100, the second magnet 200, and the third magnet 300 is not specifically limited. For example, the magnetic pole of the first magnet 100 facing the first slot wall 511 may be the south pole, while the magnetic pole of the first magnet 100 facing the first slot wall 511 may also be the north pole. The above embodiment is merely illustrative and not intended to be limiting.

[0051] For further information, please refer to Figures 1 to 3In some embodiments, the third magnet 300 is provided with at least two third magnets 300, which are arranged side by side between the first magnet 100 and the second magnet 200 along a third direction, and the magnetic poles of the at least two third magnets 300 are the same and face the first magnet 100, and the third direction is perpendicular to the first direction and the second direction. Specifically, the third magnet 300 can be two, and the two third magnets 300 are arranged side by side between one first magnet 100 and one second magnet 200. By arranging the at least two third magnets 300, the magnetic attraction capacity of the magnet group can be further improved, so that the stylus can be accurately adsorbed at a certain position of the electronic device. In addition, the simulation diagram of the magnetic induction lines of the magnet group when the third magnet 300 is two can be seen from Figure 14 , Figure 14 It can be seen that the magnetic induction lines are relatively dense and the magnetic force is relatively large at the middle position of the magnet group, so the magnet group has a relatively large magnetic attraction force.

[0052] Further, in some embodiments, the stylus further comprises an adhesive member for bonding the first magnet 100, the second magnet 200 and the third magnet 300, so as to fix the first magnet 100, the second magnet 200 and the third magnet 300 in the placement slot 510. Specifically, the adhesive member can be glue or hot melt adhesive. It can be conceived that the first magnet 100, the second magnet 200 and the third magnet 300 repel each other when arranged, so the adhesive member is needed to fix the first magnet 100, the second magnet 200 and the third magnet 300.

[0053] Further, the magnet group has other arrangements in addition to the above arrangement, specifically, please refer to Figures 4 to 5In some embodiments, the placement slot 510 includes a first slot wall 511, a second slot wall 512 and a third slot wall 513 oppositely arranged, and a fourth slot wall 514 and a fifth slot wall 515 oppositely arranged. The second slot wall 512, the third slot wall 513, the fourth slot wall 514 and the fifth slot wall 515 are connected to the first slot wall 511. That is, the shape of the placement slot 510 can be square. The shape of the magnet in the present application can also be square. The magnet group includes two first magnets 100, a second magnet 200, two third magnets 300 and two fourth magnets 400. The first magnet 100 includes an S pole and an N pole, the second magnet 200 includes an S pole and an N pole, the third magnet 300 includes an S pole and an N pole, and the fourth magnet 400 includes an S pole and an N pole. The two magnetic poles of the first magnet 100 are respectively distributed along a first direction, the two magnetic poles of the second magnet 200 are respectively distributed along the first direction, the two magnetic poles of the third magnet 300 are distributed along a second direction, and the two magnetic poles of the fourth magnet 400 are distributed along the second direction. Along the second direction, the first magnet 100, the third magnet 300, the second magnet 200, the fourth magnet 400 and the first magnet 100 are sequentially distributed, the two third magnets 300 are arranged side by side along a third direction between the first magnet 100 and the second magnet 200, and the two fourth magnets 400 are arranged side by side along the third direction between the first magnet 100 and the second magnet 200. The two magnetic poles of the third magnet 300 respectively face the first magnet 100 and the second magnet 200, and the two third magnets 300 face the same magnetic pole of the first magnet 100. Specifically, the N poles of the two third magnets 300 both face the first magnet 100, and the S poles of the two third magnets 300 both face the second magnet 200. The two magnetic poles of the fourth magnet 400 respectively face the first magnet 100 and the second magnet 200, and the two fourth magnets 400 face the same magnetic pole of the first magnet 100. Specifically, the N poles of the two fourth magnets 400 both face the first magnet 100, and the S poles of the two fourth magnets 400 both face the second magnet 200. The magnetic pole of the first magnet 100 facing the first slot wall 511 is opposite to the magnetic pole of the second magnet 200 facing the first slot wall 511, and the magnetic pole of the first magnet 100 facing the first slot wall 511 is opposite to the magnetic pole of the second magnet 200 facing the first slot wall 511. Specifically, the magnetic pole of the first magnet 100 facing the first slot wall 511 is the S pole, and the magnetic pole of the second magnet 200 facing the first slot wall 511 is the N pole. The first direction and the second direction are perpendicular, and the third direction is perpendicular to the first direction and the second direction. The first direction can be a vertical direction, the second direction can be a left-right horizontal direction, and the third direction can be a front-back horizontal direction.Specifically, by the above arrangement of the first magnet 100, the second magnet 200, the third magnet 300 and the fourth magnet 400, the centralization of the magnet group can be improved, so that the stylus can be precisely adsorbed at a specific position, instead of that the stylus is adsorbed at a specific position, the magnet group deviates from the position after the stylus is adsorbed.

[0054] It should be noted that the direction of the magnetic pole of the first magnet 100, the second magnet 200 and the third magnet 300 is not specifically limited, for example, the magnetic pole of the first magnet 100 facing the first slot wall 511 is S pole, and the magnetic pole of the first magnet 100 facing the first slot wall 511 can also be N pole. The above embodiment is only an example and is not specifically limited.

[0055] Further, in some embodiments, the stylus further comprises an adhesive for bonding the first magnet 100, the second magnet 200, the third magnet 300 and the fourth magnet 400, so that the first magnet 100, the second magnet 200, the third magnet 300 and the fourth magnet 400 are fixed in the placement slot 510. Specifically, the adhesive can be glue or hot melt adhesive. It is conceivable that the first magnet 100, the second magnet 200, the third magnet 300 and the fourth magnet 400 repel each other when arranged, so the adhesive is needed to fix the first magnet 100, the second magnet 200, the third magnet 300 and the fourth magnet 400.

[0056] Further, the magnet group has other arrangements in addition to the above arrangement, specifically, please refer to Figures 6 to 8In some embodiments, the placement slot 510 includes a first slot wall 511, a second slot wall 512 and a third slot wall 513 arranged oppositely, and a fourth slot wall 514 and a fifth slot wall 515 arranged oppositely. The second slot wall 512, the third slot wall 513, the fourth slot wall 514 and the fifth slot wall 515 are connected to the first slot wall 511. That is, the shape of the placement slot 510 can be square. The shape of the magnet in the present application can also be square. The magnet group includes a first magnet 100, a second magnet 200 and two third magnets 300. The first magnet 100 includes an S pole and an N pole, the second magnet 200 includes an S pole and an N pole, and the third magnet 300 includes an S pole and an N pole. The two magnetic poles of the first magnet 100 are respectively distributed along a first direction, the two magnetic poles of the second magnet 200 are respectively distributed along the first direction, and the two magnetic poles of the third magnet 300 are distributed along a second direction. The two third magnets 300 are sequentially distributed along the second direction, and both of the two third magnets 300 are arranged between the first magnet 100 and the second magnet 200. The two magnetic poles of one third magnet 300 respectively face the first magnet 100 and the other third magnet 300, and the two magnetic poles of the other third magnet 300 respectively face one third magnet 300 and the second magnet 200. Specifically, the N pole of the third magnet 300 faces the first magnet 100, and the S pole of the third magnet 300 faces the S pole of the other third magnet 300. Specifically, the N pole of the third magnet 300 faces the second magnet 200, and the S pole of the third magnet 300 faces the S pole of the other third magnet 300. The magnetic pole of the first magnet 100 facing the first slot wall 511 is the same as the magnetic pole of the second magnet 200 facing the first slot wall 511, and specifically, the magnetic pole of the first magnet 100 facing the first slot wall 511 is the S pole, and the magnetic pole of the second magnet 200 facing the first slot wall 511 is the S pole. The magnetic poles of the two third magnets 300 close to each other are the same, and specifically, the S pole of the third magnet 300 faces the S pole of the other third magnet 300. The first direction and the second direction are perpendicular. The first direction can be a vertical direction, and the second direction can be a horizontal direction. Specifically, by arranging the first magnet 100, the second magnet 200 and the third magnet 300 in the above manner, the centering of the magnet group can be improved, so that the stylus can be accurately adsorbed at a specific position. In addition, the magnet group deviates from the position after the stylus is adsorbed. In addition, the magnet group can be arranged in the above manner Figure 15 , Figure 15The simulation diagram of the magnetic induction lines of the magnet group of this embodiment is shown in FIG. 6. It can be seen that the magnetic induction lines are relatively dense in the middle position of the magnet group, and the magnetic force is relatively large. Therefore, the magnet group has a relatively large magnetic attraction force.

[0057] It should be noted that the orientations of the magnetic poles of the first magnet 100, the second magnet 200 and the third magnet 300 are not specifically limited. For example, the magnetic pole of the first magnet 100 facing the first slot wall 511 is an S pole, and the magnetic pole of the first magnet 100 facing the first slot wall 511 can also be an N pole. The above embodiment is only illustrative and is not specifically limited.

[0058] Further, please refer to Figure 9 In some embodiments, the magnet group includes at least two first magnets 100, at least one second magnet 200 and at least four third magnets 300. In the second direction, one second magnet 200 is located between two first magnets 100, and two third magnets 300 are arranged between the first magnet 100 and the second magnet 200. Specifically, the first magnet 100 and the second magnet 200 can be two, and the third magnet 300 can be four. In this way, by arranging at least two first magnets 100, a second magnet 200 and a third magnet 300, the magnetic attraction force of the magnet group can be further increased, thereby effectively ensuring that the precision of the stylus when adsorbing the electronic device is relatively high.

[0059] Further, the magnet group has other arrangements in addition to the above arrangement. Specifically, please refer to Figures 10 to 12In some embodiments, the placement slot 510 includes a first slot wall 511, a second slot wall 512 and a third slot wall 513 arranged oppositely, and a fourth slot wall 514 and a fifth slot wall 515 arranged oppositely. The second slot wall 512, the third slot wall 513, the fourth slot wall 514 and the fifth slot wall 515 are connected to the first slot wall 511. That is, the shape of the placement slot 510 can be square. The shape of the magnet in the present application can also be square. The magnet group includes a first magnet 100, a second magnet 200 and two third magnets 300. The first magnet 100 includes an S pole and an N pole, the second magnet 200 includes an S pole and an N pole, and the third magnet 300 includes an S pole and an N pole. The two magnetic poles of the first magnet 100 are respectively distributed along a first direction, the two magnetic poles of the second magnet 200 are respectively distributed along the first direction, and the two magnetic poles of the third magnet 300 are distributed along a second direction. The two third magnets 300 are sequentially distributed along the second direction, and both of the two third magnets 300 are arranged between the first magnet 100 and the second magnet 200. The two magnetic poles of one third magnet 300 respectively face the first magnet 100 and the other third magnet 300. Specifically, the N pole of the third magnet 300 faces the first magnet 100, and the S pole of the third magnet 300 faces the N pole of the other third magnet 300. The two magnetic poles of the other third magnet 300 respectively face one third magnet 300 and the second magnet 200. Specifically, the S pole of the third magnet 300 faces the second magnet 200, and the N pole of the third magnet 300 faces the S pole of the other third magnet 300. The magnetic pole of the first magnet 100 facing the first slot wall 511 is opposite to the magnetic pole of the second magnet 200 facing the first slot wall 511. Specifically, the magnetic pole of the first magnet 100 facing the first slot wall 511 is the S pole, and the magnetic pole of the second magnet 200 facing the first slot wall 511 is the N pole. The magnetic poles of the two third magnets 300 close to each other are opposite. Specifically, the S pole of the third magnet 300 faces the S pole of the other third magnet 300. The first direction is perpendicular to the second direction. The first direction can be a vertical direction, and the second direction can be a horizontal direction. Specifically, by arranging the first magnet 100, the second magnet 200 and the third magnet 300 as described above, the centering of the magnet group can be improved, so that the stylus can be accurately adsorbed at a specific position. In addition, the magnet group can deviate from the position after the stylus is adsorbed. For details, please refer to Figure 16 , Figure 16The simulation diagram of the magnetic induction lines of the magnet group of this embodiment is shown in FIG. 6. It can be seen that the magnetic induction lines are relatively dense in the middle position of the magnet group, and the magnetic force is relatively large. Therefore, the magnet group has a relatively large magnetic attraction force.

[0060] It should be noted that the orientations of the magnetic poles of the first magnet 100, the second magnet 200 and the third magnet 300 are not specifically limited. For example, the magnetic pole of the first magnet 100 facing the first slot wall 511 is an S pole, and the magnetic pole of the first magnet 100 facing the first slot wall 511 can also be an N pole. The above embodiment is only illustrative and is not specifically limited.

[0061] Further, please refer to Figure 13 In some embodiments, the magnet group includes at least two first magnets 100, at least one second magnet 200 and at least four third magnets 300. In the second direction, one second magnet 200 is located between two first magnets 100, and two third magnets 300 are arranged between the first magnet 100 and the second magnet 200. Specifically, the first magnet 100 and the second magnet 200 can be two, and the third magnet 300 can be four. In this way, by arranging the at least two first magnets 100, the second magnet 200 and the third magnet 300, the magnetic attraction force of the magnet group can be further increased, thereby effectively ensuring that the stylus has high accuracy when being attracted to the electronic device.

[0062] Further, it is conceivable that the magnetic attraction force of the magnet group is relatively large. When the stylus and the electronic device are attracted and connected, one side of the magnet group will face the electronic device. At this time, the other side of the magnet group can face the circuit board. Since there are many electronic elements on the circuit board, the magnetic force of the magnet group can affect the normal operation of the electronic elements. Therefore, the side of the magnet group facing the circuit board can be weakened by the placement piece 500, thereby ensuring that the stylus can work normally. Specifically, in some embodiments, the material of the placement piece 500 is one of ferrite, soft magnetic steel, graphite, silicon steel sheet, magnetic alloy, silicate ceramic, metal alloy, steel and aluminum. The materials of ferrite, soft magnetic steel, graphite, silicon steel sheet, magnetic alloy, silicate ceramic, metal alloy, steel and aluminum can effectively isolate the magnetic field and avoid affecting the circuit board, thereby ensuring the normal use of the stylus.

[0063] The embodiments of the utility model are described in detail above combined with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
