[0057] The present invention provides a stylus pen 100 .

[0058] In the embodiment of the present invention, Figures 1 to 5As shown, the stylus pen 100 comprises: a pen body 10, a shell 20, a control component 30, a pressure sensing component 40 and a magnetic component 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 component 30 is located outside the pen body 10, and the other end of the control component 30 extends into the shell 20; the pressure sensing component 40 is arranged in the shell 20 and is located in the extension direction of the control component 30, and the pressure sensing component 40 is connected to the main control unit; the magnetic component 50 is arranged in the shell 20 and is sleeved on the control component 30, and the magnetic component 50 is magnetically attracted to the shell 20 in a direction away from the pressure sensing component 40; wherein the control component 30 can move relative to the shell 20 to contact or separate from the pressure sensing component 40.

[0059] Specifically, the pen body 10 includes a pen shell and a pen tip disposed at one end of the pen shell. A main control circuit board is installed in the pen shell, and the relevant modules of the main control unit can be integrated on the main control circuit board. At the same time, the stylus pen 100 is used in conjunction with an electronic device, and the electronic device includes a display screen. When the pen tip of the stylus pen 100 contacts the display screen of the electronic device, the main control unit of the stylus pen 100 can sense the pressure of the pen tip through the sensing element, convert the pressure signal into a corresponding input command and send it to the electronic device, so that operations such as drawing, writing or browsing pages can be performed on the display screen. For the stylus pen 100, the specific structural setting of the pen body 10 can adopt the existing technology, which will not be repeated here.

[0060] In the embodiment of the present invention, a cavity is formed inside the shell 20, and an opening connecting the cavity is formed at the top of the shell 20, the pressure sensing component 40 is installed on the inner wall of the bottom end of the shell 20, the control component 30 extends from the opening of the shell 20 into the cavity of the shell 20, and the control component 30 is movably connected to the opening. The shell 20 may include an upper shell 21 and a bottom plate 22, and the upper shell 21 and the bottom plate 22 are assembled. The shell 20 and the control component 30, the pressure sensing component 40 and the magnetic component 50 installed in the shell 20 can be pre-fabricated into a modular integrated structure, which can facilitate the installation of the shell 20 and the pen body 10. The shell 20 can be installed at a position on the pen body 10 suitable for the user's finger to touch. For example, the shell 20 is installed on the side of the pen body 10 (such as Figure 1 Alternatively, the housing 20 is mounted on the end of the pen body 10 away from the pen tip (as shown in Figure 2 As shown), in this way, the user can complete the control operation by touching the control element 30 with a finger during the use of the stylus pen 100, which is flexible and convenient.

[0061] Among them, the pressure sensing element 40 is used to detect the user's pressing operation on the control element 30. The pressure sensing element 40 can specifically adopt a micro switch. The micro switch has a small contact spacing and a quick-acting mechanism. It uses a specified stroke and a specified force to perform a switching action. It is covered with a shell and has a transmission element (such as the control element 30 in the present invention) on the outside. Because the contact spacing of the switch is relatively small, it is called a micro switch, also called a sensitive switch. The external mechanical force acts on the action reed of the micro switch through the transmission element. When the action reed moves to the critical point, an instantaneous action is generated, so that the moving contact at the end of the action reed is quickly connected or disconnected with the fixed contact. The micro switch has a small appearance and can be switched with a very small force, which is convenient for installation and use. The pressure sensing element 40 can sense whether the user presses the control element 30, the number of times the control element 30 is pressed, and the length of time the control element 30 is pressed. When the pressure sensing element 40 senses the pressing information of the control element 30 , the main control unit generates corresponding instruction information according to the pressing information, and sends the instruction information to the electronic device, thereby realizing the relevant control operation.

[0062] Among them, the shell 20 is made of magnetic conductive material, that is, the shell 20 has the function of conducting magnetic force. The material with the best magnetic conductivity is pure iron. Generally, the magnetic permeability of soft magnetic materials is relatively high, including: pure iron and low carbon steel, iron-silicon alloy, iron-aluminum alloy, iron-silicon-aluminum alloy, nickel-iron alloy, iron-cobalt alloy, etc. The shell 20 is used to conduct magnetic conductivity to the magnetic component 50 inside, so that the magnetic force lines of the magnetic component 50 form a closed magnetic circuit along the shell 20, and a magnetic attraction force is generated between the magnetic component 50 and the shell 20. At the same time, in this embodiment, the setting position of the magnetic component 50 is closer to the top end of the shell 20 (the end away from the pressure sensing component 40) relative to the bottom end of the shell 20 (the end where the pressure sensing component 40 is set), so the magnetic attraction force of the top end of the shell 20 on the magnetic component 50 is stronger. In this way, when the external force is removed, the control component 30 can automatically return to the initial position before pressing (that is, the position when the magnetic component 50 abuts against the shell 20) through the magnetic attraction between the magnetic component 50 and the top end of the shell 20, thereby achieving the effect of automatic reset.

[0063] Therefore, in the technical solution of the present invention, the control component 30 on the pen body 10 can be pressed to move the control component 30 relative to the shell 20 and contact the pressure sensing component 40, and when the pressing external force is removed, the magnetic component 50 on the control component 30 and the shell 20 made of magnetic conductive material cooperate, and the control component 30 is restored to its initial position before being pressed through the magnetic attraction between the magnetic component 50 and the shell 20, thereby realizing automatic resetting of the control component 30; at the same time, the main control unit in the pen body 10 can obtain the pressing information of the control component 30 through the pressure sensing component 40, and generate corresponding command information according to the pressing information and send it to the electronic device, so as to realize operations such as adjusting and changing the input mode or input parameters of the stylus pen 100, so that the stylus pen 100 has diversified functions, simple and convenient operation, simple product structure and low production cost.

[0064] In one embodiment, see Figure 4 The stylus pen 100 further includes: a magnetic conductive member 60 , which is disposed on the control member 30 , and the magnetic conductive member 60 is located on a side of the magnetic component 50 facing the pressure sensing member 40 .

[0065] Specifically, the magnetic conductive member 60 is in a disc-shaped structure, and its diameter is adapted to the outer diameter of the magnetic component 50. The sheet-shaped magnetic conductive member 60 is attached to the surface of the magnetic component 50 on the side close to the pressure sensing component 40, and a through hole is provided in the center of the magnetic conductive member 60 for the control shaft 31 to pass through. Since the housing 20 and the magnetic conductive member 60 are both made of magnetic conductive materials, the housing 20 and the magnetic conductive member 60 can jointly conduct the magnetic force of the magnetic component 50, so that the magnetic force of the magnetic component 50 is conducted along the side wall of the housing 20, the top wall of the housing 20 and the magnetic conductive member 60, and a closed magnetic circuit is formed.

[0066] It can be understood that when the magnetic conductive member 60 is not added, the magnetic lines of force of the magnetic component 50 are conducted along the side walls of the shell 20, the top wall of the shell 20 and the bottom wall of the shell 20. After the magnetic conductive member 60 is added, the magnetic force of the lower half of the magnetic component 50 will be conducted along the magnetic conductive member 60, which greatly reduces the magnetic force of the magnetic component 50 from being conducted to the bottom wall of the shell 20. This is equivalent to the magnetic conductive member 60 shielding the conduction of the magnetic force of the magnetic component 50 on the bottom wall of the shell 20. Therefore, the magnetic attraction of the top wall of the shell 20 to the magnetic component 50 will be The magnetic attraction force of the bottom wall of the shell 20 on the magnetic component 50 is obviously stronger than that of the bottom wall of the shell 20. When the control component 30 is pressed to make the control component 30 contact with the pressure sensing component 40, when the external force is removed, the magnetic component 50 will automatically reset toward the top wall of the shell 20, and the reset force and speed are more obvious, and the reset effect is better. At the same time, adding the magnetic conductive component 60 can also reduce the restrictions on the size and position of the magnetic component 50. In addition, it can also reduce the influence of the magnetic force of the magnetic component 50 on the micro switch and the main control unit below the magnetic conductive component 60. In this embodiment, the control component 30 is reset by the magnetic conductive component 60. Compared with the conventional reset spring, the structure can be simplified, the installation is convenient, and the space occupation is saved, which is conducive to the miniaturization of the shell 20, and it is not easy to be damaged, which is conducive to extending the service life.

[0067] In one embodiment, see Figures 4 to 5 The control member 30 includes a control shaft 31, one end of which is located outside the shell 20, and the other end of the control shaft 31 extends into the shell 20, and the control shaft 31 can rotate around its axis; the magnetic component 50 includes a plurality of magnets 51, and the plurality of magnets 51 are arranged around the circumference of the control shaft 31; the stylus 100 also includes a Hall sensor 70, which is arranged on one side of the magnetic component 50 and connected to the main control unit; wherein, the magnetic poles of two adjacent magnets 51 facing the side of the Hall sensor 70 are opposite.

[0068] Specifically, the multiple magnets 51 can be an integrated structure, or the multiple magnets 51 can also be independent structures and connected together by connectors. Taking the multiple magnets 51 as an integrated structure as an example, the magnetic assembly 50 formed by the multiple magnets 51 is cylindrical as a whole, and a through hole for the control shaft 31 to pass through is opened in the center of the cylinder. One magnet 51 corresponds to one of the sector-shaped areas, and the multiple magnets 51 are arranged in sequence along the circumferential direction of the control shaft 31. Among them, the magnetization direction of the magnetic assembly 50 can be along the axial direction of the control shaft 31 or along the radial direction of the control shaft 31. Regardless of axial magnetization or radial magnetization, the multiple magnets 51 in the magnetic assembly 50 are arranged on the circumferential side of the control member 30 in the order of opposite 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. Thus, when the magnetic assembly 50 is rotated by the control shaft 31, the Hall sensor 70 can sense the change in the strength of the magnetic field of different magnets 51, and then identify the rotation position (angle) of the control shaft 31, thereby sensing whether the user rotates the control member 30 and the angle of the rotation 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, thereby realizing the relevant control operation, and the operation method is simple and convenient, the product structure is simple, easy to manufacture, and the production cost is low.

[0069] In this embodiment, the number of magnets 51 in the magnetic component 50 is set to 6. In other embodiments, the number of magnets 51 can be set according to needs. The more magnets 51 are set, the more sensing positions of the Hall sensor 70 during the rotation of the control shaft 31, and the higher the sensitivity of the product.

[0070] In one embodiment, see Figures 4 to 5 , the magnetizing directions of the multiple magnets 51 are arranged along the axial direction of the magnetic component 50, and the Hall sensor 70 is located on the radial side of the magnetic component 50; or, the magnetizing directions of the multiple magnets 51 are arranged along the radial direction of the magnetic component 50, and the Hall sensor 70 is located on the axial side of the magnetic component 50.

[0071] Specifically, when the magnetic component 50 is magnetized along the axial direction of the control shaft 31, the magnetic poles of each magnet 51 are respectively facing the top wall and the bottom wall of the shell 20. At this time, the Hall sensor 70 should be installed in the projection area of ​​the magnetic component 50 on the top wall (bottom wall) of the shell 20; when the magnetic component 50 is magnetized along the radial direction of the control shaft 31, the magnetic poles of each magnet 51 are respectively facing the side wall of the shell 20 and the axis of the control shaft 31. At this time, the Hall sensor 70 should be installed in the projection area of ​​the magnetic component 50 on the side wall of the shell 20.

[0072] Taking radial magnetization as an example, when the N pole of one of the magnets 51 faces the side wall of the housing 20, the S poles of the magnets 51 adjacent to the magnet 51 and located on both sides of the magnet 51 face the side wall of the housing 20. In this way, the magnetic component 50 can form a magnetic field with different magnetic directions and changing magnetic strengths between each two adjacent magnets 51 along the circumferential direction, and the Hall sensor 70 is located on the circumferential side of the magnetic component 50. When the magnetic component 50 is driven to rotate by the control component 30, the Hall sensor 70 will cut the magnetic lines of force of the magnetic component 50 and sense the alternating magnetic field, thereby identifying the rotation position (angle) of the magnetic component 50, that is, identifying the rotation position of the control component 30. When the Hall sensor 70 senses the rotation information of the control component 30, the main control unit will generate corresponding instruction information according to the rotation information, and send the instruction information to the electronic device, thereby realizing the relevant control operation.

[0073] In one embodiment, see Figures 6 to 7 The number of the Hall sensors 70 is two, and the two Hall sensors 70 are adjacently arranged or spaced apart along the circumferential direction of the magnetic component 50 .

[0074] Specifically, by arranging two Hall sensors 70 in the circumferential direction of the magnetic component 50, when the magnetic component 50 is driven to rotate by the control member 30, each Hall sensor 70 will sense the corresponding magnetic field change. According to the sequence of the magnetic field changes sensed by the two Hall sensors 70, the rotation direction of the magnetic component 50 can be identified, that is, it can be identified whether the magnetic component 50 rotates clockwise or counterclockwise around the axis of the control shaft 31. Among them, the two Hall sensors 70 can be arranged adjacent to each other at a relatively close distance, or directly packaged into one body to form a Hall element array. Of course, the two Hall sensors 70 can also be arranged at a relatively far distance, that is, arranged at any position along the circumferential direction of the magnetic component 50. The arrangement position and installation form of the two Hall sensors 70 can be set according to actual needs, and the present invention does not limit it.

[0075] In one embodiment, see Figures 3 to 5 The control member 30 further includes: a control portion 32 , which is disposed outside the housing 20 and fixed to the control shaft 31 , and a diameter of the control portion 32 is greater than a diameter of the control shaft 31 .

[0076] Specifically, the control shaft 31 is roughly in the shape of a slender cylinder, and the control part 32 is roughly in the shape of a wide and flat disc. Since the diameter of the control part 32 is larger than the diameter of the control shaft 31, the force area of ​​the user's finger is larger when pressing the control part 30, which can improve the pressing comfort and pressing feel, thereby enhancing the user's experience.

[0077] Furthermore, a thread is provided at one end of the control shaft 31 close to the control part 32, and a screw hole is provided on the surface of the control part 32 close to the control shaft 31. The control shaft 31 is screwed to the screw hole through the thread. In this way, a detachable connection between the control shaft 31 and the control part 32 can be achieved, which is convenient for installation and replacement of parts.

[0078] Furthermore, the control part 32 is provided with a plurality of anti-slip grooves 321 spaced apart along its circumferential side surface. Thus, when the user rotates the control part 32, the concave-convex structure formed by the plurality of anti-slip grooves 321 can increase the friction between the finger and the control part 32, making it convenient for the user to easily twist the control part 32 and realize the control of the rotation operation.

[0079] In one embodiment, see Figures 3 to 5 The stylus pen 100 also includes: a female connector and a male connector 81, wherein the female connector is disposed inside the pen body 10 and connected to the main control unit; the male connector 81 is disposed outside the shell 20, and the pressure sensing element 40 and the Hall sensor 70 are both connected to the male connector 81; wherein the male connector 81 is plugged into the female connector.

[0080] By providing a connector male seat 81 on the outer bottom surface of the housing 20 and providing a corresponding connector female seat in the pen body 10, when the housing 20 is installed on the pen body 10, the connector male seat 81 is plugged into the connector female seat, so that the pressure sensing element 40 and the Hall sensor 70 can be electrically connected to the main control unit. In this way, the pressure sensing element 40 and the Hall sensor 70 can transmit the collected signals to the main control unit through the connector female seat and the connector male seat 81, so as to monitor the user's pressing and rotating operations on the control element 30 in real time. The above connection method facilitates the installation, disassembly, replacement and maintenance of the housing 20 and the pen body 10.

[0081] In one embodiment, see Figures 3 to 5 The stylus pen 100 further includes: a flexible circuit board 82 , one end of which is connected to the pressure sensing element 40 and the Hall sensor 70 , and the other end of which extends to the outside of the housing 20 and is connected to the connector male socket 81 .

[0082] In this embodiment, the pressure sensing element 40 and the Hall sensor 70 are electrically connected to the connector male seat 81 through a flexible circuit board 82. The flexible circuit (FPC) is a printed circuit made of polyester film or polyimide as a substrate with high reliability and excellent flexibility. By embedding the circuit design on a bendable thin plastic sheet, a large number of precision components are stacked in a narrow and limited space, thereby forming a bendable flexible circuit, which has excellent properties such as light weight, thin thickness, and free bending and folding. By setting the flexible circuit board 82, circuit design is convenient and it is conducive to the miniaturization design of the product structure.

[0083] In one embodiment, see Figures 3 to 5 The stylus pen 100 further includes: an adhesive layer 91, the adhesive layer 91 is bonded to the outer wall of the shell 20, the flexible circuit board 82 extends from the shell 20 and is folded and bonded to the adhesive layer 91, and the connector male seat 81 is arranged on the surface of the flexible circuit board 82 away from the adhesive layer 91.

[0084] In this embodiment, since the connector male seat 81 is located on the outer bottom surface of the housing 20, and the pressure sensing element 40 and the Hall sensor 70 are located inside the housing 20, in order to realize the connection between the pressure sensing element 40, the Hall sensor 70 and the connector male seat 81, and fix the connector male seat 81 on the housing 20, in this embodiment, one end of the flexible circuit board 82 is extended to the outside of the housing 20, and after turning over, it is fixed to the outer bottom surface of the housing 20 through the adhesive layer 91. The adhesive layer 91 can be made of double-sided adhesive foam, which means that a strong adhesive acrylic adhesive is applied on both sides of the foam foam substrate, that is, one side surface of the foam is bonded to the outer bottom surface of the housing 20, and the other side surface of the foam is bonded to the folded back side of the flexible circuit board 82, and the connector male seat 81 is installed on the folded front side of the flexible circuit board 82. Among them, the foam double-sided adhesive has the characteristics of strong adhesion, good retention, good waterproof performance, strong temperature resistance, and shockproof buffering.

[0085] In one embodiment, see Figures 4 to 5 The stylus pen 100 further includes: a wear-resistant layer, wherein the wear-resistant layer is disposed between the contact surface of the magnetic component 50 and the shell 20 .

[0086] When the control member 30 drives the magnetic assembly 50 to move and rotate, there is collision and friction between the magnetic assembly 50 and the inner top wall of the housing 20, which easily causes wear of the contact portion between the magnetic assembly 50 and the housing 20, which easily affects the performance of the product over time. In this embodiment, by adding a wear-resistant layer between the contact portions of the magnetic assembly 50 and the housing 20, the wear of the contact portions between the two can be reduced, thereby extending the service life of the product.

[0087] In one embodiment, see Figures 4 to 5 The wear-resistant layer includes: a first gasket 92 and a second gasket 93. The first gasket 92 is attached to the inner wall of the shell 20 and seals the gap formed by the connecting shaft passing through the shell 20; the second gasket 93 is attached to the surface of the magnetic component 50 facing the first gasket 92.

[0088] In this embodiment, the wear-resistant layer is composed of a first gasket 92 and a second gasket 93. The first gasket 92 can be installed on the inner top wall of the housing 20, and the second gasket 93 can be installed on the magnetic assembly 50. The centers of the first gasket 92 and the second gasket 93 are both provided with through holes for the control shaft 31 to pass through. The first gasket 92 and the second gasket 93 are sleeved on the control shaft 31 through their respective through holes. In this way, when the magnetic assembly 50 contacts the inner wall of the housing 20, the collision and friction between the first gasket 92 and the second gasket 93 can reduce the collision and friction between the magnetic assembly 50 and the inner wall of the housing 20, thereby reducing the wear of the contact part between the magnetic assembly 50 and the housing 20, and can extend the service life of the magnetic assembly 50 and the housing 20. At the same time, the first gasket 92 can seal the opening at the top of the housing 20, so that the cavity of the housing 20 forms a closed space, which can achieve a good waterproof effect.

[0089] In one embodiment, see Figures 3 to 5 The stylus pen 100 further includes: a bracket 23 and a fastener, wherein the bracket 23 is disposed on the outer wall of the shell 20 and a fixing hole 231 is formed on the bracket 23; the fastener passes through the fixing hole 231 and is screwed to the pen body 10 so that the bracket 23 is fixed to the pen body 10.

[0090] In this embodiment, the housing 20 is fixed to the inner wall of the pen body 10 through a bracket 23. The number of brackets 23 can be set to multiple and evenly distributed along the circumferential direction of the housing 20. For example, two brackets 23 are set to be symmetrically distributed on the housing 20. Wherein, the form of the bracket 23 can be different when the installation position of the housing 20 is different. For example, when the housing 20 is installed at the end of the pen body 10 away from the pen tip, the bracket 23 extends downward along the axial direction of the housing 20, so that the bracket 23 can abut against the side wall of the pen body 10; for another example, when the housing 20 is installed on the side of the pen body 10, the bracket 23 extends outward along the radial direction of the housing 20, so that the bracket 23 can abut against the side wall of the pen body 10. During installation, fasteners such as bolts, screws, etc. are passed through the fixing holes 231 on the bracket 23 and screwed with the screw holes on the side wall of the housing 20, so that the housing 20 can be fixed on the pen body 10.

The memory as a computer storage medium can include a control program of a touch display system; and the second processor can be used to call the control program of the touch display system stored in the memory to execute the relevant steps of the control method of the touch display system.

[0117] Specifically, when the control element is pressed and / or rotated, the first processor obtains first operation information about pressing, second operation information about rotation, or third operation information about pressing and rotation through the pressure sensing element and the Hall sensor, and generates corresponding first instruction information, second instruction information, or third instruction information, and sends the above instruction information to the electronic device through the wireless sending module. After the second processor of the electronic device receives the above instruction information through the wireless receiving module, it will generate corresponding response information and output it to the control screen to control the display screen to perform the corresponding response operation.

[0118] Taking switching the pen tip function as an example, the current pen tip is a brush function. By pressing the control part, the first processor of the stylus generates an instruction to switch the eraser. When the second processor of the electronic device receives the pen tip function switching instruction sent by the stylus, it generates a response information of switching the brush to eraser and outputs it to the display screen, so that it appears as an eraser mark on the display screen.
