Referring to fig. 1, in some embodiments, a stylus 10 includes: a control assembly 100 and a charging assembly 200. The control assembly 100 includes a control board 110 and a battery 120, the control board 110 and the battery 120 being electrically connected, the battery 120 being for powering the control board 110, the control board 110 being for transmitting and receiving signals to and from an electronic device paired with the stylus 10. The electronic device may be a tablet, and it is conceivable that the stylus 10 acts capacitively with the touch pad of the tablet, i.e. that writing, drawing or operating procedures etc. may be performed on the touch screen by means of the stylus 10. After the electronic device receives the signal from the control board 110, the electronic device can sense the position of the stylus 10 on the touch screen. The principle by which the electronic device receives the signal from the control board 110 and reacts is well known and not specifically described herein.

Referring to fig. 2, the charging assembly 200 includes a magnet 210, a coil 220, and a rectifier (not shown, which may be mounted on the control board 110), and the coil 220 and the battery 120 are electrically connected to the rectifier. That is, the control board 110 and the battery 120 are electrically connected to the coil 220. After the coil 220 cuts the induction lines of the magnet 210, the coil 220 generates an alternating current, and the rectifier can change the alternating current into a direct current, thereby charging the battery 120. The charging assembly 200 may be disposed at a middle position of the stylus 10, a pen tip may be disposed at a head end of the stylus 10, and the battery 120 may be disposed at a tail end of the stylus 10. Battery 120 may be a lithium ion battery.

Wherein, when the stylus 10 moves, the coil 220 can move relative to the magnet 210 and generate current, and the rectifier can charge the battery 120 with the current generated by the coil 220. Specifically, after the battery 120 supplies power to the control board 110, the control board 110 may send or receive a signal so that the stylus 10 is connected to an electronic device, wherein when the stylus 10 moves, the coil 220 can move relative to the magnet 210 and generate current, and the rectifier can charge the battery 120 with the current generated by the coil 220; that is, when the user uses the stylus 10, the charging assembly 200 in the stylus 10 can generate current to supply power to the battery 120, so that the stylus 10 effectively avoids the situation that the battery 120 has no electric quantity, and can be used by the user all the time conveniently.

It should be noted that, when the user uses the stylus 10, the stylus 10 is not in a stationary state, and thus, the stylus 10 is in a moving state. For example, a user holds the stylus 10 while writing, drawing, rotating, and transferring the stylus 10 from one location to one location. In this moving state, the stylus 10 moves, the coil 220 moves relative to the magnet 210, and the coil 220 cuts the magnetic induction line, thereby generating current. The battery 120 of the stylus 10 may not be depleted at all times by the combined action of the coil 220 and the magnet 210. In other embodiments, the stylus 10 may be left stationary and the stylus 10 may be charged by a charger when the stylus 10 is not in use. The charging efficiency of this way is faster, and the main charging way of the stylus 10 can be used, and the way that the coil 220 and the magnet 210 charge the stylus 10 together can satisfy that the user always uses the stylus 10, thereby increasing the cruising ability of the stylus 10. Therefore, the stylus 10 is convenient for the user to use all the time, and the stylus 10 can have better cruising ability. Specifically, the stylus 10 has the characteristics of energy saving, safety and environmental protection.

In some embodiments, the charging assembly 200 is provided in plurality, and the plurality of charging assemblies 200 are each electrically connected to the control board 110. Specifically, more current can be generated through the relative movement of the coils 220 and the magnets 210 of the plurality of charging assemblies 200, and the battery 120 is charged after the current is integrated through the rectifier of the control board 110, so that the cruising ability of the stylus 10 can be increased.

The specific structure of the stylus 10 is described in detail below. Specifically, referring to fig. 2 and 3, in some embodiments, the stylus 10 includes a housing 500 and a rotator 600. The housing 500 is provided with a moving chamber 510 and a placing chamber 520 which are communicated with each other, the magnet 210 is disposed in the placing chamber 520, the coil 220 is wound around the rotating member 600, the rotating member 600 is disposed in the moving chamber 510, and the rotating member 600 is movable in the moving chamber 510 to move the coil 220 with respect to the magnet 210. Specifically, the magnet 210 is fixed to the wall of the placement chamber 520, and after the rotating member 600 is placed in the movement chamber 510, the rotating member 600 may move in the movement chamber 510, and the rotating member 600 may rotate in a rotational or linear manner. After the rotor 600 moves relative to the magnet 210, the coil 220 cuts the magnetic induction line, thereby generating an electric current. Further, in some embodiments, the housing 500 has a fixing bracket 700, the fixing bracket 700 has a moving chamber 510 and a placing chamber 520, and the magnet 210 and the rotator 600 may be mounted on the fixing bracket 700.

The manner in which the rotary member 600 linearly moves in the movement chamber 510 will be described in detail. The coil 220 is wound around the rotating member 600, the housing 500 is provided with a moving cavity 510, the moving cavity 510 may be rectangular in shape, the cavity wall of the moving cavity 510 extends along the length direction of the housing 500, the magnet 210 is fixedly connected to the inner wall of the moving cavity 510, specifically, the magnet 210 is adhered to the cavity wall of the moving cavity 510, the rotating member 600 is disposed in the moving cavity 510, and the rotating member 600 can move along the length direction of the housing 500 relative to the magnet 210. That is, the magnet 210 is disposed at one side of the rotation member 600, and when the user lifts the stylus 10, the rotation member 600 can slide along the length direction of the housing 500, that is, the rotation member 600 moves linearly, thereby cutting the magnetic induction lines.

The manner in which the mover rotates within the movement chamber 510 is described in detail below. Specifically, referring to fig. 2 and 3, in some embodiments, the housing 500 is further provided with a slot 530 communicating with the movement cavity 510, and the rotating member 600 has a rotating shaft 610, where the rotating shaft 610 is rotatably disposed in the slot 530. The central axis of the coil 220 may be parallel to the axial direction of the rotating shaft 610 or may be perpendicular to the axial direction of the rotating shaft 610. The rotation shafts 610 may be provided in two, and the two rotation shafts 610 are respectively located in the two clamping grooves 530. In this way, the rotating member 600 swings with the movement of the housing 500 by the rotation shaft 610. The rotation shaft 610 is disposed at a left end or a right end of the rotation member 600 such that the rotation member 600 can rotate with the left end of the rotation member 600 or with the right end of the rotation member 600 as an axis. When the rotator 600 rotates, the coil 220 is driven to cut the magnetic induction wire to generate current.

The rotating member 600 may be a one-piece structure. The rotary member 600 may also be of a split type construction, when the rotary member 600 is of a split type construction. In some embodiments, the stylus 10 includes a housing 500 and a rotator 600, the rotator 600 including a body and a rotation shaft 610, the coil 220 being wound on the body, the body being provided with a rotation hole, the rotation shaft 610 being located in the rotation hole. The rotation shaft 610 is fixed in the catching groove 530 (i.e., the rotation shaft 610 is fixedly coupled to the housing 500) so that the body can rotate with respect to the rotation shaft 610. In yet other embodiments, the rotator 600 includes a body around which the coil 220 is wound and a rotation shaft 610, the body being provided with a rotation hole in which the rotation shaft 610 is fixedly installed. The rotating shaft 610 is rotatably disposed in the clamping groove 530.

When the rotary member 600 rotates about the rotation shaft 610, there are two cases. In one case, the rotation shaft 610 extends in a radial direction of the cylindrical housing 500, so that a semicircular track (or a sector-shaped track, depending on a rotation amplitude) formed after the rotation of the rotation member 600 is tangential to the radial direction of the housing 500. In another case, the rotation shaft 610 extends along the axial direction of the cylindrical housing 500 (may also be the length direction of the housing 500), so that a semicircular track (or a sector track, depending on the rotation amplitude) formed by the rotation of the rotation member 600 is tangential to the axial direction of the housing 500. Specifically, referring to fig. 2, in some embodiments, the housing 500 has a predetermined length, and the rotation shaft 610 extends along the length direction of the housing 500. The length set by the housing 500 may be 15mm to 18mm. Thereby, an effect of slim appearance can be achieved. After the rotation shaft 610 extends along the length direction of the housing 500, a semicircular track (or a fan ring track, depending on the rotation amplitude) formed by the rotation of the rotation member 600 is tangential to the axial direction of the housing 500. Wherein, when a user uses the stylus 10 to draw or write, the rotating shaft 610 extends along the length direction of the housing 500, which is more beneficial for the rotating member 600 to move along with the movement of the housing 500.

Referring to fig. 1, in some embodiments, an intermediate surface 560 is defined, the intermediate surface 560 divides the housing 500 into a first portion 540 and a second portion 550 along the length direction, the tip of the stylus 10 is located at the first portion 540, and the rotator 600 and the magnet 210 are located at the second portion 550. When the user holds the stylus 10, the finger approaches the pen tip, so that the first portion 540 of the stylus 10 swings slightly, and the second portion 550 of the stylus 10 swings greatly about the finger of the user. Specifically, when the tip of the stylus 10 is located at the first portion 540 and the rotator 600 and the magnet 210 are located at the second portion 550, the rotator 600 moves effectively, and more movement can occur with respect to the magnet 210, resulting in more current.

In order to allow the user to slightly operate the stylus 10 while using the stylus 10, the rotator 600 may immediately follow the movement of the stylus 10. The rotary 600 may be provided in an eccentric configuration. Specifically, in some embodiments, the center of gravity of the rotator 600 is spaced from the central axis of the housing 500, such that a user slightly dials the stylus 10, and the rotator 600 follows the motion instantaneously.

In order to increase the magnetic field strength, the current generated when the coil 220 cuts the magnetic induction line is made larger. In a manner of disposing two magnets 210, specifically referring to fig. 2, in some embodiments, two magnets 210 are disposed, and two magnets 210 are disposed at two sides of the rotating member 600 at intervals along the axial direction of the rotating shaft 610. Wherein the N poles 211 of the two magnets 210 are disposed toward each other. That is, the N poles 211 of both magnets 210 are facing the rotor 600 and the s poles 212 are facing away from the rotor 600. It should be noted that the N poles 211 of the two magnets 210 may be disposed opposite to each other. That is, the N pole 211 of one magnet 210 faces the rotor 600 and the s pole 212 faces away from the rotor 600. The S-pole 212 of the other magnet 210 faces the rotor 600 and the n-pole 211 faces away from the rotor 600. Reference is made in particular to figures 2 and 3. In addition, two magnets 210 may be disposed at intervals on both sides of the rotator 600 along the radial direction of the rotation shaft 610.

In order to increase the magnetic field strength, there are other ways than the above. Specifically, referring to fig. 4, in some embodiments, the charging assembly 200 further includes a soft magnetic member 400, wherein the soft magnetic member 400 is made of a soft magnetic material, and the soft magnetic member 400 may be pure iron, low carbon steel, silicon steel sheet, permalloy, ferrite, or the like. After the soft magnetic member 400 is provided, the magnetic field strength can be increased, so that the current generated by the coil 220 is large. Further, the soft magnetic member 400 may be mounted in such a manner that the rotating member 600 is provided with a through hole 620 (the through hole 620 may refer to fig. 2), the soft magnetic member 400 is disposed through the through hole 620, and the soft magnetic member 400 is fixedly connected to the housing 500, that is, two ends of the soft magnetic member 400 are respectively connected to two cavity walls of the moving cavity 510.

Further, since the rotating member 600 rotates around the rotation shaft 610, its movement trace is in the shape of a semicircle or a fan ring. Accordingly, the soft magnetic member 400 may be designed to adapt to the shape of the movement trace of the rotating member 600. Specifically, referring to fig. 4, in some embodiments, the soft magnetic member 400 is in a fan-ring shape with the center of the rotating shaft 610 as the center. This can increase the magnetic field strength without obstructing the movement of the rotating member 600 by the soft magnetic member 400 while ensuring a large volume of the soft magnetic member 400.

Referring to fig. 1, in some embodiments, the stylus 10 further includes an electrode 800, the electrode 800 is electrically connected to the control board 110, and the control board 110 is used to control the electrode 800 to send and receive signals to and from the electronic device, and at least part of the electrode 800 is exposed outside the housing 500. The housing 500 includes a nib, a barrel, and a tail. At least a portion of the electrode 800 is exposed to the housing 500 to form a nib. When the electrode 800 is in contact with the touch screen of the electronic device, the control board 110 may provide a signal to the electrode 800 and control the electrode 800 to transmit a signal to the electronic device to determine the position of the stylus 10. This provides the advantage of a fast response and low latency to the stylus 10, which can enhance the user experience.

In addition, when a user writes on the touch screen using the stylus 10, the thickness of the input font can be displayed by the pressing force of the stylus 10 on the touch screen, specifically, referring to fig. 1, in some embodiments, the stylus 10 further includes a pressure sensor 910, the pressure sensor 910 is electrically connected to the control board 110, the control board 110 supplies power to the pressure sensor 910, the pressure sensor 910 is connected to the electrode 800, and the pressure sensor 910 is used for detecting the pressure applied to the electrode 800. Specifically, after the pressure sensor 910 senses the pressure, a signal is transmitted to the control board 110, and the control board 110 transmits a signal to the electronic device through the electrode 800, so that the electronic device can receive the signal and display the thickness of the font according to the size of the pressure. The technology of displaying font thickness after the electronic device receives the signal belongs to common general knowledge, and is not specifically described herein.

In addition, in some embodiments, the electrode 800 and the pressure sensor 910 may be connected through both ends of the conductive rod 900, respectively, so that when the user presses the stylus 10, the electrode 800 receives a pressure on the touch screen, and under the reaction of the force, the electrode 800 transmits the pressure to the conductive rod 900, and the conductive rod 900 transmits the pressure to the pressure sensor 910, so that the pressure sensor 910 may detect the pressure received by the electrode 800.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model. Furthermore, embodiments of the utility model and features of the embodiments may be combined with each other without conflict.
