It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

With the development of communication technology, mobile terminals such as mobile phones and tablet computers have become an indispensable tool. When using mobile terminals such as a mobile phone and a tablet, an accessory such as a capacitive pen is often used to implement operations such as writing or drawing on a screen. In the related art, the pen point of the capacitance pen is often configured to be detachably connected, so that the capacitance pen is convenient to replace when the pen point is worn to a certain extent, but a part of counterfeit pen point components appear on the market, and the problems that a screen is damaged in the use process possibly exist because the pen point components are not officially verified. Meanwhile, nib components produced by the same manufacturer have different types, and the nib components of different types have different parameters such as touch feeling, friction force and the like when in use, so that when in use on different electronic equipment, the nib components have different service lives, correct identification of the nib is very important, and when using counterfeit nib components or nib components with unmatched types, terminals such as a mobile phone, a tablet computer and the like can prompt a user about nib related information in time.

Based on this, the inventors of the present application have proposed a nib assembly, a capacitive pen, and an electronic device assembly of various embodiments of the present application to improve the above-described drawbacks. Embodiments of the present application are specifically described below with reference to the accompanying drawings.

As shown in fig. 1, the present embodiment provides an electronic device assembly 1 including an electronic device 20 and a capacitive pen 10. The electronic device 20 includes a housing 21, a display 22, a motherboard, a battery, a front camera, and the like. The main board and the battery are arranged in the shell 21, and the front camera is arranged on one side of the electronic device 20 where the display screen 22 is arranged. The electronic device 20 provided in this embodiment will be described by taking a mobile phone as an example.

The front shell 212 and the rear cover 213 are respectively assembled on two opposite sides of the middle plate 2111, and the front shell 212 and the rear cover 213 are assembled and fixed with the frame 2112; the rear cover 213, the middle frame 211 and the front shell 212 together form a containing cavity, various components such as a main board, a camera, an antenna, a processor and the like can be arranged in the containing cavity, and the rear cover 213 can be provided with a camera mounting hole for mounting a rear camera.

With continued reference to fig. 1, in which the display 22 is mounted on the front case 212, the display 22 may employ an LCD (Liquid CRYSTAL DISPLAY) screen for displaying information, and the LCD screen may be a TFT (Thin Film Transistor ) screen or an IPS (In-PLANE SWITCHING, in-plane switching) screen or an SLCD (Splice Liquid CRYSTAL DISPLAY, split-panel Liquid crystal display) screen. In other embodiments, the display 22 may employ an OLED (Organic Light-Emitting Diode) screen for displaying information, the OLED screen may be an AMOLED (Active Matrix Organic LIGHT EMITTING Diode) screen or a Super AMOLED (Super Active Matrix Organic LIGHT EMITTING Diode) screen or a Super AMOLED Plus (Super Active Matrix Organic LIGHT EMITTING Diode Plus, magic screen) screen, which will not be described herein, and the display 22 may be a touch display.

In some embodiments, the housing 21 may further be provided with a jack 212, specifically, as shown in fig. 2, the jack 212 is disposed on the frame 2112 of the middle frame 211, and the jack 212 penetrates the frame 2112 and communicates with the accommodating cavity. The jack 212 may be disposed at any position of the frame 2112, preferably, the frame 2112 may include a first frame and a second frame disposed along a length direction, and a third frame and a fourth frame disposed along a width direction, the first frame and the second frame are opposite, the third frame is opposite to the fourth frame, and the first frame and the second frame are connected between the third frame and the fourth frame. The receptacles 212 may be located adjacent to other rims 2112 of any of the rims 2112, for example: the jack 212 is disposed at a position of the third frame adjacent to the first frame or the second frame, or the jack 212 is disposed at a position of the fourth frame adjacent to the first frame or the second frame. The arrangement mode is beneficial to the arrangement of other components in the accommodating cavity and prevents mutual interference.

Referring again to fig. 1, the axis of the receptacle 212 may be generally parallel to the length of the electronic device 20 so that the receptacle 212 may be used to insert longer objects. Of course, it is understood that in other embodiments, the receptacles 212 may also be disposed along the width of the electronic device 20.

The capacitive pen 10 is capable of being inserted into the receptacle 212 and removably connected to the electronic device 20. Of course, in other embodiments, the jack 212 may not be provided, and the capacitive pen 10 may be stored in other manners or separately. Referring to fig. 3 and fig. 4 together, the capacitive pen 10 includes a nib assembly 11, a pen holder 12, and a plurality of detection circuits 13 electrically isolated from each other, wherein the nib assembly 11 can be detachably connected to the pen holder 12, and the detection circuits 13 are disposed in the pen holder 12. In some embodiments, the pen holder 12 may be in a telescopic structure, and this arrangement is beneficial to adjusting the length of the pen holder 12 and facilitating storage. Illustratively, when the barrel 12 is inserted into the receptacle 212, the barrel 12 may be shortened to enable the barrel 12 to be fully received into the receptacle 212. When the pen holder 12 is separated from the electronic device 20, the pen holder 12 can be elongated, and the longer length can be more convenient to hold during the use of the pen holder 12. Of course, it will be appreciated that in other embodiments, the barrel 12 may take other forms, such as a folding barrel 12, without limitation.

In some embodiments, capacitive pen 10 may also include a communication module 14, with communication module 14 being configured for communicative connection with electronic device 20.

Specifically, the cross-section of the barrel 12 may be square or circular, which is not limited herein. Referring to fig. 5, one end of the barrel 12 is provided with a coupling hole 122 (shown in fig. 6), and the coupling hole 122 is for coupling with the nib assembly 11. (again, the form of the lower coupling hole, the internal structure) the barrel 12 further includes an inner wall 123 surrounding the coupling hole 122.

Referring to fig. 4 and fig. 5, each of the detecting circuits 13 includes a first detecting end 131 and a second detecting end 132. The first detecting end 131 and the second detecting end 132 are disposed on the inner wall 123.

The plurality of detection circuits 13 are electrically isolated from each other, where the plurality of detection circuits 13 are electrically isolated from each other means that the plurality of detection circuits 13 do not interfere with each other, i.e., on/off of any one detection circuit does not affect on/off of other detection circuits 13, in some embodiments, the plurality of detection circuits 13 may be independent from each other, in some embodiments, at least two of the plurality of detection circuits 13 may form a parallel circuit, which is not limited in this embodiment.

Referring to fig. 6, the nib assembly 11 includes a nib 111, a connector 112 and a plurality of detecting elements 113. When the connector 112 is inserted into the connection hole 122, each of the detecting elements 113 is used for conducting a detecting circuit, specifically, one detecting element 113 is electrically connected between the first detecting end 131 and the second detecting end 132 of the same detecting circuit 13, so that the detecting circuit 13 forms a passage, and the detecting circuit is conducted.

The pen head 111 contacts the display 22 when in use, so the material and structure of the pen head 111 are related to whether the pen head 111 will scratch the display 22, and the wear of the pen head 111 is an important criterion for measuring the life of the pen head assembly 11. In this embodiment, the pen tip 111 may be a pen tip 111 made of a soft material. Specifically, the pen tip 111 may be made of soft plastic (TPU) or hard plastic (RTP). In other embodiments, the pen tip 111 may be made of other soft materials, and the specific materials are not limited herein.

The pen points 111 of different brands and models may be made of different materials, and may be different in structural design, so that the performances of the pen points 111 of different brands and models are different when used on the screen of the same electronic device 20, such as the writing length, the abrasion degree of the pen points 111 on the display screen 22, and the like. And since the nib assembly 11 is detachable and self-replaceable, when a user misuses the nib assembly 11 of another brand or another model, it is very easy to form scratches on the display screen 22 of the electronic device 20, and the writing and drawing quality is lowered, and it is necessary to give a reminder to the user when this occurs.

In this embodiment, with continued reference to FIG. 6, the nib 111 has an opposite tip 1111 and a connecting end 1112. In use, the tip 1111 is configured to contact the display screen 22 and may be slid over the display screen 22. A connection end 1112 opposite the tip 1111 is used to connect to the connector 112. By way of example, the nib 111 may be generally configured as a cone, a truncated cone, etc., without limitation. The connecting end 1112 is located at the bottom surface of the tapered nib 111. The connecting end 1112 may be a spherical groove formed on the bottom surface, and when the connecting end 1112 is connected to the connecting head 112, the connecting end 1112 is partially embedded into the spherical groove, so as to avoid separation between the pen point 111 and the connecting head 112.

The connector 112 may also be integrally combined with the connection end 1112, in other embodiments, the connection end 1112 and the pen head 111 may be connected by other connection methods, such as threaded connection, or may be detachably connected by a male-female fastener or shaft hole, so that only a part of the parts may be replaced when the parts are damaged, thereby reducing the cost. The specific connection manner of the connection end 1112 and the pen tip 111 is not limited herein.

The connector 112 is used for connecting the pen holder 12 with the pen tip assembly 11, and the detection circuit 13 can be electrically connected and conducted with the pen tip assembly 11 through the connector 112. In this embodiment, the connecting head 112 may be substantially cylindrical, and one end of the connecting head 112 is connected to the nib 111, and the other end of the connecting head 112 may be inserted into the connecting hole 122 to detachably connect the pen shaft 12 and the nib assembly 11.

Specifically, as an embodiment, referring to fig. 5 and 6, an end of the connector 112 away from the pen head 111 may be provided with a mounting portion 1121. The mounting portion 1121 may be a concave structure formed on a side wall of the cylindrical connector 112, and correspondingly, a clamping member 1231 may be disposed on an inner wall 123 surrounding the connecting hole 122, where the clamping member 1231 may be a spring piece, or may be an elastic structure disposed in other manners, and is not limited herein. Specifically, in the present embodiment, taking a spring piece as an example, the locking piece 1231 is elastically disposed in the connecting hole 122 and connected to the inner wall 123, when the connector 112 is inserted into the connecting hole 122, one end of the connector 112 far from the pen point 111 contacts first, and the locking piece 1231 deforms the locking piece 1231. When the connection projection 122 is completely inserted into the connection hole 122, the clamping member 1231 is restored and embedded into the mounting portion 1121 under the action of the elastic force, so as to realize the detachable connection between the pen holder 12 and the pen tip assembly 11.

In some embodiments, the connector 112 may also be communicatively connected to the electronic device 20 via the communication module 14 of the barrel 12. As an embodiment, the connector 112 may be a TX electrode, i.e. a transmitting electrode of the capacitive pen 10, for transmitting a downlink signal to the electronic device 20 through the pen shaft 12, and providing information such as the position and writing pressure of the pen. In the present application, a plurality of detecting elements 113 are disposed on the connector 112, and are used to cooperate with the detecting circuit 13 to realize the identification of the pen point 111.

Specifically, the plurality of detecting elements 113 are disposed on the outer wall of the connecting head 112 and are electrically insulated from each other. Specifically, the detecting element 113 itself serves as one conductor, and any two points on one detecting element 113 are electrically connected. As an embodiment, referring to fig. 7, each detecting element 113 includes a first connecting end 1131 and a second connecting end 1132 connected to each other, and the first connecting end 1131 and the second connecting end 1132 are exposed from the outer wall of the connecting head 112. The detecting member is configured to conduct a detection loop as shown in fig. 7 through the first connection end 1131 and the second connection end 1132 when the connector 112 is inserted into the connection hole 122.

In other embodiments, the detecting member 113 may further include more connection terminals, such as a third connection terminal and a fourth connection terminal, which are in communication with a detecting circuit different from the first connection terminal and the second connection terminal. Specifically, the conductive detection circuit may be a signal circuit, and one detection element 113 may also conduct different electrical signals that do not interfere with each other, so that one detection element 113 may also conduct multiple detection circuits, and the number and types of the conductive circuits are not limited herein.

As an embodiment, referring to fig. 5 and 6 again, the connecting head 112 may have a length direction (as indicated by the arrow in fig. 6), and in this embodiment, the length direction may be along the axial direction of the cylindrical connecting head 112. The plurality of detecting elements 113 may be disposed at intervals in the longitudinal direction, and the first detecting ends 131 and the second detecting ends 132 located in different loops are disposed in the connecting hole 122 at intervals while being offset in the axial direction of the connecting hole 122. The space in the connection hole 122 can be more reasonably used by the first electrode 113 and the second electrode 114 which are arranged in a staggered manner.

Specifically, each detecting member 113 is configured as an annular structure surrounding the length direction of the connecting head 112, and the detecting member 113 may be an integrally formed metal ring, and the metal ring is sleeved on the outer side of the cylindrical connecting head 112. In the present embodiment, the first detecting end 131 and the second detecting end 132 may be metal bumps disposed on the inner wall 123 of the connecting hole 122. Correspondingly, the first detecting end 131 and the second detecting end 132 may be symmetrically disposed along the length direction of the connection hole 122. Thus, when the connector 112 is inserted into the connecting hole 122, since the plurality of detecting elements 113 are staggered and spaced apart in the length direction, and the plurality of pairs of first detecting ends 131 and second detecting ends 132 are also spaced apart in the connecting hole 122, one detecting element 113 is electrically connected to only one first detecting end 131 and one second detecting end 132, and conducts one detecting circuit.

Since the detecting member 113 is annular, the metal bumps forming the first detecting end 131 and the second detecting end 132 are always in contact with the annular detecting member if the entire nib assembly 11 rotates in the connecting hole 122 after the connector 112 is inserted into the connecting hole 122. Through such design, nib subassembly 11 is connected with pen-holder 12 with arbitrary angle, can both guarantee that the detection piece can switch on first detection end 131 and second detection piece 132.

The detecting members 113 conduct the detecting circuits 13 to identify the nib assemblies 11. As an embodiment, referring to fig. 8, when the number of the detecting elements 113 is greater than 3, the intervals between any two adjacent detecting elements 113 are not equal. It can be understood that, if the plurality of detecting elements 113 are disposed on the connector 112 at intervals, and if the interval between two adjacent detecting elements 113 is a for a certain type of nib assembly 11, the interval between two adjacent first detecting ends 131 or two adjacent second detecting ends 132 should be a for a pen shaft 12 matched with the nib assembly 11, so that a plurality of detecting circuits can be conducted when the nib assembly 11 matched with each other is connected with the pen shaft 12. By detecting whether different detection loops are conducted, the identification of the model corresponding to the nib assembly 11 or the authenticity of the nib assembly 11 can be realized. The detection member 113 may not be disposed at a corresponding position in the nib assembly 11 of a manufacturer different from the electronic device 20, and when such nib assembly 11 is inserted into the connection hole 112, the detection circuit 13 is not turned on, so that it is also possible to identify whether the nib assembly 11 is genuine or matches the electronic device 20.

Specifically, as an embodiment, referring to fig. 6 again, the outer wall of the connector 112 may be provided with a groove 1122, and a plurality of detecting elements are disposed in the groove 1122 at intervals. It can be appreciated that the plurality of detecting members 113 may be staggered in the length direction of the connector 112, and the detecting members 113 configured into a ring shape may make the overall structure more compact and stronger when disposed in the groove 1122, and the detecting members 113 are not easy to fall off from the connector.

As a more specific embodiment, the joint 112 may include a first segment 1123, a second segment 1124, and a third segment 1125. The second section 1124 is connected between the first section 1123 and the third section 1125, and the groove 1122 is disposed on the second section 1124. Specifically, the grooves 1122 may be disposed annularly about the second section 1124, i.e., about the length of the connector 112. Specifically, the third section 1125 is configured to connect to the pen head 11, and the mounting portion 1121 is disposed on the first section 1123. By such design, the first section 1123 may be part of the TX electrode and is connected to the third section 1125 through the second section 1124, the third section 1125 is connected to the nib 11 and may obtain writing pressure, position, etc. data from the nib 11, and by such design, the structure of the nib assembly 11 may be made more compact.

It will be appreciated that, since the connector 112 needs to be inserted into the connecting hole 122, the surface formed by connecting the connector 112 with the surfaces of the plurality of detecting members 113 cannot have too large a gap, so that smooth insertion into the connecting hole 122 can be ensured, so as an embodiment, when the detecting members are disposed in the grooves on the second section 1124, the outer side surfaces of the detecting members can be flush with the surfaces of the first section 1123 and the third section 1125 on the connector 112, so that the surface of the connector 112 is smoother and convenient for insertion into the connecting hole 122.

Because of the compact structure of the nib assembly 11, the conductors that are in close proximity to each other may be conductive, resulting in a short circuit. In some embodiments, therefore, the nib assembly 11 may further include an insulating member 116, the insulating member 116 being located between adjacent detecting members 113 for isolating adjacent detecting members 113. Specifically, the insulating member 116 may be disposed in a gap formed between the adjacent detecting member 113 and the connecting head 112. The insulating member 116 may be a rubber insulating member or a rigid plastic insulating member, and the specific material is not limited herein. The insulating member 116 may be a second section 1124 directly sleeved on the connecting head 112, so that the design is more compact.

For the same reason, conduction may occur between the plurality of detecting pieces and the connection head 112. In some embodiments, the insulating member 116 is also located between the detecting member 113 and the connecting head 112. Specifically, the insulating member 116 may be disposed on an outer side surface of the connection head 112 and also extend along gaps formed between the plurality of detecting members 113 and the connection head 112. Through such design, the conduction between the detecting members 113 and the connecting heads 112 can be avoided, so that different parts have better insulation effect.

In the nib assembly 11 provided in this embodiment, when the connector 112 is inserted into the connecting hole 122, a detecting member passes through the first detecting end 131 and the second detecting end 132 and forms a current loop as shown in fig. 7. As an embodiment, referring to fig. 4 again, the capacitive pen 10 may further include a processing module 15 and a prompting device 16. The prompting device 16 may be electrically connected to the processing module 15 and the plurality of detection circuits 13. The processing module 15 may determine whether the nib assembly 11 currently inserted into the connection hole 122 is an authorized product, such as the nib assembly 11 under official production or the nib assembly 11 under official authorized production, according to the conduction conditions of the plurality of detection circuits, the detection circuit 13 may obtain the conduction conditions of the plurality of detection circuits as shown in fig. 9, and the processing module 15 may match the conduction conditions of the nib assembly 11 under authorized product according to the conduction conditions of the plurality of detection circuits. The prompting device 16 may be a buzzer, a vibrator, etc., and when the matching result is not the nib assembly 11 of the authorized product, the prompting device 16 may issue a prompting message, which may be a sound or a vibration message.

In other embodiments, the communication module 14 may send the determination result of the processing module 15 to the electronic device 20, and when the matching result is not the nib component 11 of the authorized product, the electronic device 20 may display a prompt message on the display screen 22, where the prompt message may be, for example, pop-up window information (as shown in fig. 10). When the matching result is the nib assembly 11 of the authorized product, no processing can be performed, or a prompt such as that the nib assembly 11 is correctly inserted or connected can be displayed.

Example 2

Unlike embodiment 1, in this embodiment, the detecting member 113 may be a rod-shaped detecting member. Specifically, the opposite ends of the detecting member 113 respectively form a first connecting end 1131 and a second connecting end 1132, and the first detecting end 1131 and the second detecting end 1132 are exposed to the outer wall of the connecting head 112. By this design, the detection element can also be designed to conduct a detection circuit 13.

Specifically, the detecting member 113 may be perpendicular to the length direction of the connector and is disposed on the connector 112 in a penetrating manner, so that the first connecting end 1131 and the second connecting end 1132 are symmetrically disposed along the length direction of the connector. Correspondingly, the first detecting end 131 and the second detecting end 132 may be configured as arcs, and the first detecting end 131 and the second detecting end 132 may be substantially 180 ° arcs, so as to be disposed around the inner wall of the connecting hole 122. And the first detecting end 131 and the second detecting end 132 are insulated from each other. By such design, when the connector 112 is inserted into the connection hole 122, the first detecting end 131 contacts with the first connecting end 1131, and the second detecting end 132 contacts with the second connecting end 1132, so as to form a detecting circuit through the detecting member 113. It can be understood that, because the detecting member 113 is a conductor, when the connector 112 is inserted into the connecting hole 122 at a specific angle, the first detecting end 131 contacts the second connecting end 1132, and the second detecting end 132 contacts the first connecting end 1131, so that the entire nib assembly 11 rotates in the connecting hole 122, and the first detecting end 131 and the second detecting end 132 are always connected through the detecting member 113. By designing in this way, the nib assembly 11 is connected to the barrel 12 at any angle, so that the detecting element 113 can be guaranteed to conduct the first detecting end 131 and the second detecting end 132.

In other embodiments, the detecting members may be disposed parallel to the length direction of the connecting head 112, and the detecting members are disposed around the central axis of the connecting head 112, so that the first connecting end 1131 and the second connecting end 1132 are disposed at intervals in the length direction of the connecting head 112. Correspondingly, the first detecting end 131 and the second detecting end 132 are also disposed on the inner wall of the connecting hole 122 and are disposed at intervals along the length direction of the connecting hole 122, so that the first detecting end 131 and the second detecting end 132 can be connected through the detecting member 113.
