The present invention provides a stylus 100.

In an embodiment of the present invention, as shown in fig. 1 to 5, the stylus 100 includes: the pen comprises a pen body 10, a shell 20, a control part 30, a pressure sensing part 40 and a magnetic assembly 50, wherein a main control unit is arranged in the pen body 10; the shell 20 is arranged in the pen body 10, and the shell 20 is made of a magnetic conductive material; one end of the control member 30 is located outside the pen body 10, and the other end of the control member 30 extends into the casing 20; the pressure sensing element 40 is arranged in the shell 20 and located in the extending direction of the control element 30, and the pressure sensing element 40 is connected with the main control unit; the magnetic component 50 is disposed in the casing 20 and sleeved on the control member 30, and the magnetic component 50 is magnetically attracted with the casing 20 along a direction away from the pressure sensing member 40; wherein the control member 30 is movable relative to the housing 20 to be in contact with or separated from the pressure sensing member 40.

Specifically, the pen body 10 includes a pen shell and a pen point disposed at one end of the pen shell, a main control circuit board is installed in the pen shell, and related modules of the main control unit can be integrated on the main control circuit board. Meanwhile, the stylus 100 is used in cooperation with an electronic device, the electronic device includes a display screen, and when a pen point of the stylus 100 contacts the display screen of the electronic device, a main control unit of the stylus 100 can sense the pressure of the pen point through an induction element, convert a pressure signal into a corresponding input instruction and send the input instruction to the electronic device, so that operations such as drawing, writing or browsing a page can be performed on the display screen. For the stylus 100, the specific structural configuration of the pen body 10 can be implemented by the prior art, and will not be described herein.

In the embodiment of the present invention, a cavity is formed inside the housing 20, an opening communicated with the cavity is formed at the top end of the housing 20, the pressure sensing element 40 is installed on the inner wall of the bottom end of the housing 20, the control element 30 extends into the cavity of the housing 20 from the opening of the housing 20, and the control element 30 is movably connected with the opening. The housing 20 may include an upper shell 21 and a bottom plate 22, the upper shell 21 and the bottom plate 22 are assembled, and the housing 20, the control member 30, the pressure sensing member 40 and the magnetic assembly 50 installed in the housing 20 may be prefabricated into a modular integrated structure, which may facilitate the installation of the housing 20 and the pen body 10. The housing 20 can be installed on the pen body 10 at a position suitable for being touched by a finger of a user, for example, the housing 20 is installed on a side surface of the pen body 10 (as shown in fig. 1), or the housing 20 is installed at an end of the pen body 10 away from the pen point (as shown in fig. 2), so that the user can complete a control operation by touching the control element 30 with the finger during using the stylus pen 100, which is flexible and convenient.

The pressure sensing member 40 is used to detect the pressing operation of the control member 30 by the user, and the pressure sensing member 40 may be a micro switch, which is a switch having a minute contact interval and a snap action mechanism, performing a switching operation with a predetermined stroke and a predetermined force, covered with a housing, and having a transmission element (such as the control member 30 in the present invention) outside, and is called a micro switch, also called a sensitive switch, because the contact interval of the switch is relatively small. The external mechanical force acts on the action reed of the microswitch through the transmission element, and the action reed generates instantaneous action when moving to a critical point, so that the movable contact at the tail end of the action reed is quickly connected with or disconnected from the fixed contact. The micro-gap switch appearance is less, can use very little dynamics to switch, easy to assemble and use. Whether the user presses the control 30 and the number of times the control 30 is pressed and the length of time the control 30 is pressed are sensed by the pressure sensing member 40. When the pressure sensing member 40 senses the pressing information of the control member 30, the main control unit generates corresponding instruction information according to the pressing information and transmits the instruction information to the electronic device, thereby implementing related control operations.

The casing 20 is made of a magnetic material, that is, the casing 20 has a magnetic force. The best magnetic permeability material is pure iron, and the magnetic permeability of the general soft magnetic material is higher, including: pure iron, low carbon steel, iron-silicon alloys, iron-aluminum alloys, iron-silicon-aluminum alloys, nickel-iron alloys, iron-cobalt alloys, and the like. Carry out the magnetic conduction through casing 20 to magnetic component 50 in it, make magnetic component 50's magnetic line of force form closed magnetic circuit along casing 20, and make and produce magnetic attraction between magnetic component 50 and the casing 20, and simultaneously, in this embodiment, magnetic component 50's the position that sets up is for casing 20's bottom (the one end that sets up pressure-sensitive part 40) more is close to casing 20's top (the one end of keeping away from pressure-sensitive part 40), so the top of casing 20 is stronger to magnetic attraction of magnetic component 50, so, when removing external force, through the magnetic attraction effect between magnetic component 50 and the casing 20 top, can make control 30 automatic recovery to the initial position before pressing (namely the position when magnetic component 50 and casing 20 butt), thereby realize automatic re-setting's effect.

Therefore, in the technical scheme of the invention, the control member 30 can move relative to the casing 20 to contact with the pressure sensing member 40 by pressing the control member 30 on the pen body 10, and when the pressing external force is removed, the magnetic component 50 on the control member 30 is matched with the casing 20 made of magnetic conductive material, so that the control member 30 is restored to the initial position before pressing through the magnetic attraction effect between the magnetic component 50 and the casing 20, and the automatic reset of the control member 30 is realized; meanwhile, the main control unit in the pen body 10 can acquire the pressing information of the control element 30 through the pressure sensing element 40, generate corresponding instruction information according to the pressing information, and send the instruction information to the electronic device, so that the operations of adjusting and changing the input mode or input parameters of the stylus 100 can be realized, and the stylus 100 has diversified functions, simple and convenient operation mode, simple product structure and low production cost.

In an embodiment, referring to fig. 4, the stylus 100 further includes: the magnetic conduction member 60 is disposed on the control member 30, and the magnetic conduction member 60 is located on a side of the magnetic assembly 50 facing the pressure sensing member 40.

Specifically, the magnetic conducting member 60 is a disk-shaped structure, the diameter of the magnetic conducting member 60 is matched with the outer diameter of the magnetic assembly 50, the disk-shaped magnetic conducting member 60 is attached to the surface of the magnetic assembly 50 close to the pressure sensing member 40, and a through hole for the control shaft 31 to pass through is formed in the center of the magnetic conducting member 60. Because the casing 20 and the magnetic conducting member 60 are made of magnetic conducting materials, the casing 20 and the magnetic conducting member 60 can conduct the magnetic force of the magnetic assembly 50 together, so that the magnetic force of the magnetic assembly 50 is conducted along the side wall of the casing 20, the top wall of the casing 20 and the direction of the magnetic conducting member 60, and a closed magnetic circuit is formed.

It can be understood that, when the magnetic conducting member 60 is not added, the magnetic force lines of the magnetic assembly 50 are conducted along the side wall of the casing 20, the top wall of the casing 20 and the bottom wall of the casing 20, after the magnetic conducting member 60 is added, the magnetic force of the lower half part of the magnetic assembly 50 is conducted along the magnetic conducting member 60, so that the magnetic force of the magnetic assembly 50 is greatly reduced to be conducted to the bottom wall of the casing 20, which is equivalent to the fact that the magnetic conducting member 60 shields the conduction of the magnetic force of the magnetic assembly 50 on the bottom wall of the casing 20, therefore, the magnetic attraction of the top wall of the casing 20 to the magnetic assembly 50 is obviously stronger than the magnetic attraction of the bottom wall of the casing 20 to the magnetic assembly 50, under the condition that the control member 30 is pressed to contact the pressure sensing member 40, when the external force is removed, the magnetic assembly 50 automatically resets toward the top wall of the casing 20, the resetting force and speed are more obvious, the resetting effect is better, and meanwhile, the limitation on the size and the position of the magnetic assembly 50 can also be reduced by adding the magnetic conducting member 60, in addition, the influence of the magnetic force of the magnetic assembly 50 on the micro switch and the main control unit below the magnetic conducting member 60 can be reduced. In this embodiment, the control member 30 is reset by the magnetic conductive member 60, which simplifies the structure, facilitates installation, saves space, facilitates miniaturization of the housing 20, is not easily damaged, and prolongs the service life compared with a conventional reset spring.

In an embodiment, referring to fig. 4 to 5, the control member 30 includes a control shaft 31, one end of the control shaft 31 is located outside the housing 20, and the other end of the control shaft 31 extends into the housing 20, and the control shaft 31 can rotate around its axis; the magnetic assembly 50 includes a plurality of magnets 51, and the plurality of magnets 51 are disposed around the circumference of the control shaft 31; the stylus 100 further comprises a hall sensor 70, and the hall sensor 70 is arranged on one side of the magnetic assembly 50 and connected with the main control unit; wherein, the magnetic poles of two adjacent magnets 51 facing the hall sensor 70 are opposite.

Specifically, the plurality of magnets 51 may be an integral structure, or the plurality of magnets 51 may be separate structures and connected together by a connecting member. Taking the plurality of magnets 51 as an integral structure, the magnetic assembly 50 formed by the plurality of magnets 51 is cylindrical as a whole, a through hole for the control shaft 31 to pass through is formed in the center of the cylinder, one magnet 51 corresponds to one of the sector areas, and the plurality of magnets 51 are sequentially arranged along the circumferential direction of the control shaft 31. The magnetizing direction of the magnetic assembly 50 may be along the axial direction of the control shaft 31, or along the radial direction of the control shaft 31. Whether axially or radially magnetized, the plurality of magnets 51 in the magnetic assembly 50 are arranged on the peripheral side of the control member 30 in an opposite order of magnetic poles, that is, the magnetic poles of any two adjacent magnets 51 facing the hall sensor 70 are opposite, so that magnetic fields with different directions are formed between different magnets 51. In this way, when the magnetic assembly 50 is rotated by the control shaft 31, the hall sensor 70 can sense the strength change of the magnetic field of the different magnets 51, and thus recognize the rotational position (angle) of the control shaft 31, thereby sensing whether the user rotates the control member 30 and the angle of the rotary control member 30. When the hall sensor 70 senses the rotation information of the control member 30, the main control unit generates corresponding instruction information according to the rotation information and sends the instruction information to the electronic device, so that related control operation is realized, the operation mode is simple and convenient, the product structure is simple, the production and the manufacturing are convenient, and the production cost is low.

In this embodiment, the number of the magnets 51 in the magnetic assembly 50 is set to 6, in other embodiments, the number of the magnets 51 can be set according to the requirement, and the more the magnets 51 are set, the more the sensing positions of the hall sensor 70 are in the rotating process of the control shaft 31, and the higher the sensitivity of the product is.

In one embodiment, referring to fig. 4 to 5, the magnetizing directions of the magnets 51 are arranged along the axial direction of the magnetic assembly 50, and the hall sensor 70 is located at one side of the magnetic assembly 50 in the radial direction; alternatively, the magnetizing directions of the plurality of magnets 51 are arranged along the radial direction of the magnetic assembly 50, and the hall sensor 70 is located at one axial side of the magnetic assembly 50.

Specifically, when the magnetic assembly 50 is magnetized along the axial direction of the control shaft 31, the magnetic pole of each magnet 51 faces the top wall and the bottom wall of the housing 20, and at this time, the hall sensor 70 should be installed in the projection area of the magnetic assembly 50 on the top wall (bottom wall) of the housing 20; when the magnetic assembly 50 is magnetized along the radial direction of the control shaft 31, the magnetic pole of each magnet 51 faces the sidewall of the housing 20 and the axial center of the control shaft 31, and then the hall sensor 70 should be installed on the projection area of the magnetic assembly 50 on the sidewall of the housing 20.

Taking radial magnetization as an example, when the N pole of one of the magnets 51 faces the sidewall of the housing 20, the S poles of the magnets 51 adjacent to the magnet 51 and located at two sides of the magnet 51 face the sidewall of the housing 20, so that the magnetic assembly 50 can form magnetic fields with different magnetic force directions and varying magnetic force intensity between each two adjacent magnets 51 along the circumferential direction, and the hall sensor 70 is located at the circumferential side of the magnetic assembly 50, when the control member 30 drives the magnetic assembly 50 to rotate, the hall sensor 70 will cut the magnetic force lines of the magnetic assembly 50 and sense the magnetic fields that are alternately varied, thereby identifying the rotational position (angle) of the magnetic assembly 50, i.e. identifying the rotational position of the control member 30. When the hall sensor 70 senses the rotation information of the control member 30, the main control unit generates corresponding instruction information according to the rotation information and transmits the instruction information to the electronic device, thereby implementing related control operations.

The two hall sensors 70 can be adjacently arranged at a relatively short distance, or directly packaged into a whole to form a hall element array. Of course, the two hall sensors 70 may be arranged at a relatively large distance, i.e., at any position in the circumferential direction of the magnetic assembly 50. The arrangement positions and the installation forms of the two hall sensors 70 can be set according to actual needs, and the invention is not limited.
