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 the problem that the pen point is partially imitated in the market, and the like possibly damages a screen in the using process because the pen point is not officially verified. Meanwhile, the official nibs have different models, and the nib assemblies of different models have different parameters such as touch feeling, friction force and the like when in use, so that the difference of service lives exists when in use on different electronic equipment, and correct identification of nibs is very important.

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 D CRYSTA L DI SP L AY, liquid crystal display) screen for displaying information, and the LCD screen may be a TFT (TH I N F I LM TRANS I stor ) screen or an isps (I n-PL ANE SWITCH I NG, planar switching) screen or an SLCD (Sp l ice L iqu ID CRYSTA L DI SP L AY, liquid crystal display dedicated for splicing) screen. In other embodiments, the display 22 may employ an OLED (organic light-EMITT I NG DI ode) screen for displaying information, the OLED screen may be an AMOLED (ACT IVE MATR ix organic IC L I GHT EMITT I NG Diode) screen or a Super AMOLED (Super ACT IVE MATR ix organic I C LI GHT EMITT I NG DI ode) screen or Super AMOLED Pl us (Super ACT I VE MATR ix organic IC LI GHT EMITTI NG DI ode P us) 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 can be disposed at any position of the frame 2112, preferably, the frame 2112 can 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 is opposite to the second frame, the third frame is opposite to the fourth frame, and the first frame is opposite to the second frame
Is 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.
The axis of the receptacle 212 may be generally parallel to the length of the electronic device 20 such 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 detection circuit 13, wherein the nib assembly 11 can be detachably connected to the pen holder 12, and the detection circuit 13 is 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, the detection circuit 13 includes a first detection end 131 and a second detection end 132. The first detecting end 131 and the second detecting end 132 are disposed on the inner wall 123.
Referring to fig. 6, the nib assembly 11 includes a nib 111, a connector 112, a first detecting electrode 113, a second detecting electrode 114 and a detecting resistor 115. When the connector 112 is inserted into the connection hole 122, the first detecting end 131 may contact and electrically communicate with the first detecting electrode 113, and the second detecting end 132 may contact and electrically communicate with the second detecting electrode 114.
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 other brands or other models which is not officially verified, it is extremely 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, 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 connection end 1112 may be a spherical groove formed on the bottom surface, when the connection end 1112 is connected to the connector 112, the connection end 1112 is partially embedded into the spherical groove, so that the separation between the pen point 111 and the connector 112 can be avoided, the connector 112 can be integrally combined with the connection end 1112, in other embodiments, the connection end 1112 and the pen point 111 can be connected in other connection manners, such as a male-female buckle or shaft hole matching connection, or the like, or in a detachable connection manner, so that only a part of the parts can 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 is 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, the 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 application, the first detection electrode 113, the second detection electrode 114 and the detection resistor 115 are arranged on the connector 112, and are used for being matched with the detection circuit 13 to realize the identification of the pen point 111.
Specifically, the first detection electrode 113 is disposed on the outer wall of the connector 112, the second detection electrode 114 is also disposed on the outer wall of the connector 112, and the detection resistor 115 is disposed in the connector 112 and electrically connected to the first detection electrode 113 and the second detection electrode 114, specifically, the first detection electrode 113 and the second detection electrode 114 are respectively connected to two ends of the detection resistor 115, that is, the first detection electrode 113, the second detection electrode 114 and the detection resistor 115 are connected in series. The first detection electrode 113 and the second detection electrode 114 are used for electrically connecting the detection circuit 13 and the detection resistor 115 when the connector 112 is inserted into the connection hole 122, so as to form a detection loop as shown in fig. 7.
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 first detection electrode 113 and the second detection electrode 114 may be disposed offset in the longitudinal direction, and the first detection end 131 and the second detection end 132 are disposed offset in the axial direction of the connection hole 122 in the connection 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, the first detection electrode 113 is formed in a ring shape around the longitudinal direction. The first detecting electrode 113 may be an integrally formed metal ring, and the metal ring is sleeved on the outer side of the cylindrical connector 112. The second detection electrode 114 is also formed in a ring shape around the longitudinal direction, similar to the first detection electrode 113, and may be an integrally formed metal ring, and is sleeved outside the connection 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. When the connector 112 is inserted into the connecting hole 122, the first detecting electrode 113 and the second detecting electrode 114 are staggered in the length direction, so that the first detecting electrode 113 only contacts the first detecting end 131 and is conducted with the first detecting end 131, and the second detecting electrode 114 only contacts the second detecting end 132 and is conducted with the second detecting end 132. Since the first detection electrode 113 and the second detection electrode 114 are both annular, the entire pen tip assembly 11 rotates within the connection hole 122 after the connection head 112 is inserted into the connection hole 122, and the metal bump forming the first detection end 131 is always in contact with the metal ring forming the first detection electrode 113, and the metal bump forming the second detection end 132 is also always in contact with the metal ring forming the second detection electrode 114. By such design, the nib assembly 11 is connected with the pen holder 12 at any angle, so that the first detection electrode 113 is ensured to be conducted with the first detection end 131, and the second detection electrode 114 is ensured to be conducted with the second detection end 132.
In other embodiments, the first detecting end 131 and the second detecting end 132 may have other shapes, such as a metal ring disposed along the axis of the connecting hole 122. Specifically, the first detecting end 131 and the second detecting end 132 may be metal rings staggered along the length direction of the connecting hole 122, and the metal rings are connected to the inner wall of the connecting hole 122. In the present embodiment, the first detection electrode 133 and the second detection electrode 114 may not be annular, but may be protruding points that are offset in the longitudinal direction of the connector 112, and by such a design, when the connector 112 is connected to the connection hole 122, the first detection electrode 113 is in conduction with the first detection terminal 131, and the second detection electrode 114 is in conduction with the second detection terminal 132.
The first detection electrode 113 and the second detection electrode 114 are electrically connected with the detection resistor 115, so as to realize the identification of the detection resistor 115 by the detection circuit 13. It will be appreciated that the resistance of the sensing resistor 115 may be a predetermined value, and that the resistances of the sensing resistors 115 may be different in different types of nib assemblies 11 from the same manufacturer. By detecting the magnitude of the current flowing through the detection resistor 115 at a fixed voltage, the model of the corresponding nib assembly 11, the authenticity of the nib assembly 11, and the like can be identified. The detection resistor may not be provided 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, the outer wall of the connector 112 may be provided with a groove 1122, the detection resistor 115 is disposed in the groove 1122, and the first detection electrode 113 and the second detection electrode 114 are respectively disposed at two ends of the detection resistor 115 and are electrically connected to the detection resistor 115. It can be understood that the first detection electrode 113 and the second detection electrode 114 may be staggered in the length direction, and since the first detection electrode 113 and the second detection electrode 114 are respectively disposed at two ends of the detection resistor 115, the first detection electrode 113 and the second detection electrode 114 have a certain interval in the length direction, so that the first detection electrode 113 and the second detection electrode 114 can be ensured to be connected only through the detection resistor 115, and the situations of short circuit and the like caused by direct contact conduction between the first detection resistor 115 and the second detection resistor 115 are avoided.
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. In this embodiment, the sensing resistor 115 may also be annular, which is more rapid in the manufacturing and assembly process of the nib assembly 11. Specifically, the annular detecting resistor 115 may be sleeved on the second section 1124 and embedded in the groove 1122, and the first detecting electrode 113 is electrically connected with the detecting resistor 115 and is adjacent to the first section 1123, and it is understood that the annular first detecting electrode 113 may contact one end face of the detecting resistor 115 in an abutting manner. The second detection electrode 114 is the same as the first detection electrode 113, the annular second detection electrode 114 is electrically connected with the detection resistor 115 and is adjacent to the third section 1125, and may also be in contact with an end surface of the detection resistor 115 away from the first detection electrode 113. By such design, the whole structure can be more compact and firm.
In the present embodiment, the direct contact of the first detection electrode 113 and the second detection electrode 114 with the detection resistor 115 is merely a simple embodiment, and in other embodiments, the first detection electrode 113 and the second detection electrode 114 may be connected to the detection resistor 115 by other structures, for example, by a conductor of a suitable shape, and the specific connection method is not limited herein.
It will be appreciated that, since the connector 112 needs to be inserted into the connection, the surface formed by connecting the connector 112, the first detecting electrode 113 and the second detecting electrode 114 cannot have too large a gap, so that smooth insertion into the connection hole 122 can be ensured, so that, as an embodiment, the radial diameters of the first detecting electrode 113 and the second detecting electrode 114 can be larger than the detecting resistor 115, and meanwhile, the portion of the first detecting electrode 113 protruding the detecting resistor 115 extends toward the second detecting electrode 114, and the portion of the second detecting electrode 114 protruding the detecting resistor 115 also extends toward the first detecting electrode 113, so that the first detecting electrode 113 and the second detecting electrode 114 can wrap the detecting resistor 115.
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 comprise a first insulating member 116, the first insulating member 116 being located between the first detection electrode 113 and the second detection electrode 114 for isolating the first detection electrode 113 from the second detection electrode 114. Specifically, the first insulating member 116 may be disposed in a gap formed between the first detecting electrode 113 and the second detecting electrode 114 on the connecting head 112. The first insulating member 116 may be a rubber insulating member or a rigid plastic insulating member, and the specific material is not limited herein. The first insulating member 116 may be directly sleeved on the outer side of the detection resistor 115, so that the design structure is more compact.
For the same reason, conduction may occur between the first and second detection electrodes 113 and 114 and the connection head 112. In some embodiments, the nib assembly 11 may further include a second insulating member 117 and a third insulating member 118, the second insulating member 117 being used to isolate the first detection electrode 113 from the connection head 112, and the third insulating member 118 being used to isolate the second detection electrode 114 from the connection head 112. Specifically, the second insulating member 117 may be sleeved on the second section 1124 and located between the first detection electrode 113 and the first section 1123. The third insulator 118 is sleeved on the second section 1124 and is located between the second detection electrode 114 and the third section 1125. By such a design, conduction between the first and second detection electrodes 113 and 114 and the connection head 112 can be avoided. It should be noted that the second insulating member 117 and the third insulating member 118 may be disposed on the outer side surface of the connecting head 112, or may extend along a gap formed between the first detecting electrode 113 and the second detecting electrode 114 and the connecting head 112, so as to have a better insulating effect, and the specific shapes of the second insulating member 117 and the third insulating member 118 are not limited.
In the nib assembly 11 provided by the application, when the connector 112 is inserted into the connecting hole 122, the first detecting end 131 is conducted with the first detecting electrode 113, and the second detecting end 132 is conducted with the second detecting electrode 114, so that a current loop as shown in fig. 7 is formed. 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 detection circuit 13. The detection circuit 13 may obtain the impedance value of the detection resistor 115 by applying a fixed voltage between the first detection terminal 131 and the second detection terminal 132. The processing module 15 may match the impedance value obtained by the detection circuit 13 with the impedance value of the detection resistor 115 in the official-verified nib assembly 11. The prompting device 16 may be a buzzer, a vibrator, etc., and the prompting device 16 may send out a prompting message when the matching result is that the nib assembly 11 is not officially verified, or the nib assembly 11 is not in accordance with the model.
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. 8). When the matching result is the authorized nib assembly 11, no processing can be performed, or a prompt message such as that the nib assembly 11 is correctly inserted or connected can be displayed.
The electronic device 20 in the present application may be a mobile Phone or a smart Phone (e.g., i Phone-based, andro i d TM Phone-based), a portable gaming device (e.g., N i ntendo DS TM, P l ayStat i on Portab l e TM, gameboy ADVANCE TM, i Phone-based), a laptop, a PDA, a portable internet device, a music player, and a data storage device, other handheld devices, and devices such as watches, headphones, pendants, headphones, etc., and the electronic device 20 may also be other wearable devices (e.g., head-mounted devices (HMDs) such as e-glasses, e-clothing, e-bracelets, e-necklaces, e-tattoos, e-devices, or smart watches).
The electronic device may also be any of a number of electronic devices 20, the number of electronic devices 20 including, but not limited to, cellular telephones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, cameras, other media recorders, radios, medical devices, vehicle transportation equipment, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbooks, personal Digital Assistants (PDAs), portable Multimedia Players (PMPs), moving picture experts group (MPEG-1 or MPEG-2) audio layer 3 (MP 3) players, portable medical devices, and digital cameras, and combinations thereof.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
