[0056] In order to make the objects, technical solutions and advantages of the present application clearer, the following will be combined with the drawings of the preferred embodiments of the present application to describe the technical solutions in the embodiments of the present application in a more detailed manner. In the drawings, identical or similar reference numerals indicate identical or similar components or components with identical or similar functions throughout. The described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work under the premise of the present application, all belong to the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0057] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood in a broad sense, for example, the first connection can also be indirectly connected through an intermediate medium, and can be the internal communication of two elements or the interaction relationship of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0058] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0059] The terms "first", "second", "third" (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0060] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or display including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0061] A touch panel is arranged on an electronic device such as an interactive smart panel or a tablet computer, and the touch panel serves as an operation interface for a user to operate in a touch manner, thereby improving the convenience of use. The electronic device is usually equipped with a stylus, and the user can hold the stylus to perform information interaction operation, thereby improving the convenience and accuracy of operating the touch panel.

[0062] A receiving portion and a stylus detection structure are arranged on the electronic device. The receiving portion is used to receive the stylus. When the user uses the stylus, the stylus can be taken out from the receiving portion, and when the stylus is not used, the stylus is put back into the receiving portion. The stylus detection structure includes a magnetic sensor and a magnet. When the stylus made of metal material approaches and moves away from the magnet, the magnetic sensor detects whether the stylus is placed in the receiving portion by the change of the magnetic field generated by the magnet. In this way, the stylus is prevented from being lost.

[0063] However, the electronic device also has ferrous parts. For example, the ferrous parts can be a ferrous back cover, a bracket for fixing the magnet, or a screw. The ferrous parts near the magnet will interfere with the magnetic field of the magnet, and finally cause the data read by the magnetic sensor to be inaccurate. When the interference is large, the function can even be disabled.

[0064] Therefore, the embodiment of the present application provides a stylus detection structure and an electronic device. The stylus detection structure moves towards the circuit board body through the conductive adsorption assembly and contacts the circuit board body, so that the first conductive part and the second conductive part are conducted through the conductive adsorption assembly, and a trigger signal for analyzing and judging the placement state of the stylus is generated. In this way, even if the ferrous parts on the electronic device, the detection effect of the present application cannot be affected, thereby improving the accuracy of the stylus detection structure in detecting the placement state of the stylus.

[0066] Referring to Figures 1 to 8As shown, the handwriting pen detection structure 100 provided by the embodiment of the present application is used for detecting the placement state of the handwriting pen 210 in the electronic device 200. The handwriting pen detection structure 100 comprises a circuit board and a conductive adsorption component 120. The circuit board comprises a circuit board body 110 and a conductive component 130. The circuit board body 110 is provided with a plug-in port 111. The conductive component 130 comprises at least one first conductive piece 131 and at least one second conductive piece 132. The first conductive piece 131 and the second conductive piece 132 are both arranged on the same surface of the circuit board body 110. The first conductive piece 131 and the second conductive piece 132 are both electrically connected with the plug-in port 111. The first conductive piece 131 and the second conductive piece 132 are insulated from each other.

[0067] The conductive adsorption component 120 is arranged on the second conductive piece 132. The conductive adsorption component 120 is used for adsorbing the handwriting pen 210. The conductive adsorption component 120 can also serve as a conductor. When the handwriting pen 210 triggers the conductive adsorption component 120 to move towards the circuit board body 110, the first conductive piece 131 and the second conductive piece 132 are electrically connected through the conductive adsorption component 120, and a trigger signal for analyzing and judging the placement state of the handwriting pen is generated. The plug-in port 111 is used for transmitting the trigger signal.

[0068] In the embodiment, the first conductive pieces 131 and the second conductive pieces 132 are arranged on the same surface of the circuit board body 110 and are arranged at intervals. The circuit board body 110 is provided with a plurality of wires. Each first conductive piece 131 can be electrically connected with the plug-in port 111 on the circuit board body 110 through a wire. Similarly, each second conductive piece 132 can also be electrically connected with the plug-in port 111 on the circuit board body 110 through another wire.

[0069] When the handwriting pen detection structure 100 is installed, the circuit board body 110 faces the display surface of the electronic device 200. The plug-in port 111 can be electrically connected with the mainboard 230 on the electronic device 200. The mainboard 230 is provided with a processor. Alternatively, the circuit board body 110 is provided with a processor. The plug-in port 111 is electrically connected with the processor on the circuit board body 110. The embodiment is described by taking the plug-in port 111 being electrically connected with the processor on the mainboard 230.

[0070] Figure 9 The position of the conductive adsorption component and the circuit board in the handwriting pen detection structure provided by the embodiment of the present application Figure 1 . Referring to Figure 4 and Figure 9As shown, when the stylus 210 is not placed on the region corresponding to the stylus detection structure 100 of the electronic device 200, there is a gap between the conductive adsorption component 120 and the circuit board body 110, and the conductive adsorption component 120 is not in contact with the circuit board body 110. At this time, the first conductive part 131 and the second conductive part 132 cannot be conducted, and thus a trigger signal cannot be formed.

[0071] Figure 10 Positioning diagram of the conductive adsorption component and the circuit board in the stylus detection structure provided by the embodiment Figure 2 As shown in FIGS. 1 and 2, the stylus detection structure 100 includes a circuit board body 110, a conductive adsorption component 120, and a conductive component 130. Figure 4 and Figure 10 As shown, when the stylus 210 is fixedly placed on the region corresponding to the stylus detection structure 100 of the electronic device 200, the conductive adsorption component 120 has an adsorption force to adsorb the stylus 210, so that the stylus 210 triggers the conductive adsorption component 120 to move towards the circuit board body 110 until the conductive adsorption component 120 is in contact with the circuit board body 110. At this time, the first conductive part 131 and the second conductive part 132 are electrically connected through the conductive adsorption component 120, and a trigger signal is generated. The trigger signal is transmitted to the main board 230 of the electronic device 200 through the plug-in port 111. After the processor on the main board 230 receives the trigger signal, it can be determined that the stylus 210 is placed on the electronic device 200.

[0072] The stylus detection structure 100 provided by the embodiment includes the circuit board body 110, the conductive adsorption component 120, and the conductive component 130. The first conductive part 131 and the second conductive part 132 of the conductive component 130 are located on the same surface of the circuit board body 110. The conductive adsorption component 120 is arranged on the second conductive part 132. When the stylus 210 approaches the stylus detection structure 100, the conductive adsorption component 120 adsorbs the stylus 210, and the conductive adsorption component 120 moves towards the circuit board body 110 and is in contact with the circuit board body 110, so that the first conductive part 131 and the second conductive part 132 are conducted through the conductive adsorption component 120, and a trigger signal for analyzing and determining the placement state of the stylus 210 is generated. In the prior art, a magnetic sensor is used to detect whether the stylus 210 is placed on the electronic device 200 by sensing the change of the magnetic field. In the present application, the conduction state of the first conductive part 131 and the second conductive part 132 is realized by the movement of the conductive adsorption component 120, which avoids the dependence on the change of the magnetic field and external electromagnetic interference. Therefore, even if there are ferrous parts on the electronic device 200, they cannot affect the detection effect of the present application, thereby improving the accuracy of the stylus detection structure 100 in detecting the placement state of the stylus 210. Moreover, the present application avoids using electronic sensor devices, which can save costs.

[0073] It can be understood that the stylus 210 can trigger the partial conductive adsorption assembly 120 to move towards the circuit board body 110. Specifically, the conductive adsorption assembly 120 can include a first part and a second part, the first part and the second part can be connected by a conductive spring, the second part is arranged on the second conductive piece 132, and the first part corresponds to the first conductive piece 131. The stylus 210 can trigger the first part to move relative to the second part to make the first part contact the first conductive piece 131. The stylus 210 can also trigger the conductive adsorption assembly 120 as a whole to move towards the circuit board body 110.

[0074] Hereinafter, the stylus 210 triggers the conductive adsorption assembly 120 as a whole to move towards the circuit board body 110.

[0075] Please continue to refer to Figure 8 and Figure 10 As shown, when the conductive adsorption assembly 120 moves towards the circuit board body 110, the second conductive piece 132 is compressed towards the circuit board body 110 to make the conductive adsorption assembly 120 contact the first conductive piece 131. When the stylus 210 is removed, the second conductive piece 132 extends towards the side away from the circuit board body 110 to make the conductive adsorption assembly 120 contact the first conductive piece 131.

[0076] The second conductive piece 132 of the embodiment is telescopic, which drives the conductive adsorption assembly 120 connected to the second conductive piece 132 to contact or contact the first conductive piece 131, thereby enabling the automatic reset of the conductive adsorption assembly 120.

[0077] In specific implementation, the first conductive piece 131 can be a pad, thereby the first conductive piece 131 can be formed at the same time as the circuit board body 110 is formed. The second conductive piece 132 can be a conductive silicone column, which can be assembled to the circuit board body 110 by surface mounting technology. In order to facilitate the compression of the second conductive piece 132, a compression through slot 1321 is arranged on the conductive silicone column. The compression through slot 1321 can be arranged in the middle region of the second conductive piece 132, thereby making the deformation of the second conductive piece 132 more concentrated, avoiding the compression of the second conductive piece 132.

[0078] Figure 11 The structure of the conductive adsorption assembly in the stylus detection structure provided by the embodiment of the application is shown. Please refer to Figure 9 and Figure 11As shown, the stylus detection structure 100 provided in this embodiment includes a conductive adsorption component 120 comprising a metal bracket 121 and a magnetic conductive element 122. The metal bracket 121 is connected to the second conductive element 132. The magnetic conductive element 122 is adsorbed onto the metal bracket 121 and is located between the circuit board body 110 and the metal bracket 121, with a gap between the magnetic conductive element 122 and the circuit board body 110. The magnetic conductive element 122 is used to adsorb the stylus 210. The magnetic conductive element 122 and the metal bracket 121 move towards the circuit board body 110 simultaneously, so that the magnetic conductive element 122 covers the first conductive element 131.

[0079] Specifically, the magnetic conductive component 122 is a magnet capable of conducting electricity. Thus, while attracting the stylus 210, the first conductive component 131 and the second conductive component 132 are electrically connected through the magnetic conductive component 122 and the metal support 121. Nickel-copper-nickel plating can be applied to the surface of the magnet to increase its conductivity.

[0080] The metal bracket 121 is used to mount the magnetic conductive component 122. The magnetic conductive component 122 is generally a regular shape, such as a cylinder, cuboid, or cube. The metal bracket 121 can be an irregular shape. The metal bracket 121 allows the magnetic conductive component 122 to be closer to the circuit board body 110, thereby improving the sensitivity of the stylus detection structure 100.

[0081] To facilitate the installation of the magnetic conductive element 122, in some embodiments, the metal bracket 121 has a mounting groove, and the magnetic conductive element 122 is disposed in the mounting groove.

[0082] In a specific implementation, the metal bracket 121 includes a support plate 1212 and a side plate 1213. The side plate 1213 is connected to one side of the support plate 1212, and the support plate 1212 is connected to the second conductive element 132. At least one end of the side plate 1213 has a bent portion 1214. The support plate 1212, the side plate 1213, and the bent portion 1214 together form a mounting groove. The support plate 1212, the side plate 1213, and the bent portion 1214 can be integrally formed. The metal bracket 121 can be formed by bending the support plate 1212, the side plate 1213, and the bent portion 1214, thereby facilitating the formation of the mounting groove.

[0083] The surface of the magnetic conductive component 122 abuts against the support plate 1212, and the side plate 1213 and the bent portion 1214 abut against different surfaces of the magnetic conductive component 122 respectively.

[0084] Specifically, the magnetic conductive component 122 is in Figure 11 The surface of the support plate 1212 in the Z direction abuts against the support plate 1212, and the magnetic conductive element 122 is in Figure 11The side surface in the Y direction abuts against the side plate 1213, and the magnetically conductive member 122 is in contact with the side plate 1213 in the X direction. Figure 11 The end surface in the X direction abuts against the bent part 1214, and thus the magnetically conductive member 122 is limited in the mounting groove formed by the support plate 1212, the side plate 1213 and the bent part 1214.

[0085] Please continue to refer to Figure 8 and Figure 9 , Figure 11 As shown in the drawings, the handwriting pen detection structure 100 provided in the embodiment has at least two first conductive members 131 and two second conductive members 132, and each first conductive member 131 is located between the two second conductive members 132; the magnetically conductive member 122 is located between the two second conductive members 132. By arranging two second conductive members 132, the second conductive members 132 can stably support the support plate 1212. By arranging at least two first conductive members 131, the first conductive members 131 can be distributed at different positions of the circuit board body 110, thereby increasing the contact area of the magnetically conductive member 122 and the first conductive members 131. Even if the circuit board body 110 is not flat, the magnetically conductive member 122 can still effectively contact the first conductive members 131.

[0086] Specifically, Figure 11 The X direction in the drawings is the extension direction of the metal support 121, and the two ends of the extension direction of the metal support 121 can have a connecting part 1211, which can be connected with the second conductive member 132 one by one. The connecting part 1211 can be provided with a mounting hole 1215, and the conductive adsorption assembly 120 can be connected to the electronic device 200 through the mounting hole 1215, thereby realizing the function of adsorbing the handwriting pen 210 on the electronic device 200.

[0087] Please continue to refer to Figure 1 , Figure 4 and Figure 8 In some embodiments, the wire insertion port 111 has a positive electrode pin 1111 and a negative electrode pin 1112, one of the positive electrode pin 1111 and the negative electrode pin 1112 is electrically connected with the first conductive member 131, and the other is electrically connected with the second conductive member 132. For example, the second conductive member 132 can be connected with the negative electrode pin 1112 through the wire of the circuit board body 110 as a negative electrode, and the first conductive member 131 can be connected with the positive electrode pin 1111 through the wire of the circuit board body 110 as a positive electrode. By arranging the positive electrode pin 1111 and the negative electrode pin 1112 in the wire insertion port 111, it is convenient to connect with the mainboard 230 through the connecting line.

[0088] Figure 12 Part of the structure schematic diagram of the handwriting pen detection structure provided in the embodiment. Please refer to Figure 1 , Figure 3, Figure 9 , Figure 11 and Figure 12 As shown, the stylus detection structure 100 provided in this embodiment also includes a housing 140, which has a receiving cavity 141. The housing 140 covers the circuit board body 110, and the first conductive element 131, the second conductive element 132, and the conductive adsorption assembly 120 are all located within the receiving cavity 141. By providing the housing 140, the first conductive element 131, the second conductive element 132, and the conductive adsorption assembly 120 are protected.

[0089] In a specific implementation, the receiving cavity 141 has a plurality of wire ribs 142. The extension direction of the wire ribs 142 is consistent with the movement direction of the conductive adsorption component 120. The wire ribs 142 are respectively spaced on both sides of the extension direction of the conductive adsorption component 120, and the wire ribs 142 abut against the side of the conductive adsorption component 120.

[0090] The direction of movement of the conductive adsorption component 120 is as follows: Figure 11 In the Z direction, the extension of the conductive adsorption component 120 is reversed. Figure 11 In the X direction, when the conductive adsorption component 120 moves, the guide wire 142 provides a limiting and guiding function for the movement of the conductive adsorption component 120.

[0091] Specifically, the two sides of the extending direction of the conductive adsorption component 120 can be the side plate 1213 and the side of the magnetic conductive member 122 opposite to the side plate 1213, respectively. The side plates 1213 and the side of the magnetic conductive member 122 opposite to the side plate 1213 are respectively in contact with at least two wire ribs 142, thereby increasing the stability of the movement of the conductive adsorption component 120.

[0092] In some embodiments, the receiving cavity 141 further includes a plurality of limiting ribs 143, which are located at both ends of the extending direction of the conductive adsorption assembly 120. The limiting ribs 143 define the installation position of the conductive adsorption assembly 120.

[0093] The stylus detection structure 100 provided in this embodiment has at least one notch 144 on each of the two sides of the housing 140 extending in the direction of extension. An elastic buckle 145 is located within the notch 144 and engages with the side of the circuit board body 110 opposite to the first conductive element 131. Through the deformation of the elastic buckle 145, the housing 140 engages with the circuit board body 110, thereby fixing the first conductive element 131, the second conductive element 132, and the conductive adsorption assembly 120 within the receiving cavity 141.

[0094] Understandably, after the housing 140 is snapped into the circuit board body 110, the support plate 1212 can abut against the inner wall of the receiving cavity 141. That is, the second conductive element 132 and the support plate 1212 are fixed by the housing 140 and the circuit board body 110. At this time, the support plate 1212 can simply overlap the second conductive element 132 without needing to be connected to the support plate 1212 on the second conductive element 132 by adhesive or other fixing methods. In other words, the connecting part 1211 overlaps with the second conductive element 132 in a one-to-one correspondence.

[0095] Specifically, the extension direction of the shell 140 is... Figure 11 In the X-direction, the notches 144 on the two sides of the housing 140 extending in the X-direction can be symmetrically arranged or staggered. This embodiment does not impose any restrictions on this.

[0096] In this embodiment, the housing 140 has a clearance groove 146, and the plug port 111 is located in the clearance groove 146. The clearance groove 146 provides guidance for the connecting wire connected to the plug port 111, thereby facilitating the connection of the connecting wire to the plug port 111.

[0097] In some embodiments, the housing 140 also has at least one positioning hole 147. Thus, the stylus detection structure 100 is initially positioned on the electronic device 200 through the positioning hole 147, thereby improving the assembly accuracy of the stylus detection structure 100.

[0098] Figure 13 for Figure 4 A structural diagram of the bottom middle border; Figure 14 for Figure 13 Another structural diagram from this angle. See also... Figures 1 to 14 As shown, this embodiment also provides an electronic device 200, including a stylus 210, a device body 220, and a stylus detection structure 100 provided in the above embodiment. The stylus detection structure 100 is disposed on the device body 220, and the circuit board body 110 of the stylus detection structure 100 faces the display surface of the device body 220.

[0099] The structure and working principle of the stylus detection structure 100 have been described in detail in the above embodiments, and will not be repeated here.

[0100] The device body 220 includes a motherboard 230, and the positive pin 1111 and negative pin 1112 of the stylus detection structure 100 are electrically connected to the motherboard 230 via a connecting cable.

[0101] In the embodiment, when the stylus 210 is fixedly placed on the area corresponding to the stylus detection structure 100 of the electronic device 200, the conductive adsorption component 120 has an adsorption force to adsorb the stylus 210, so that the stylus 210 triggers the conductive adsorption component 120 to move towards the circuit board body 110 until the conductive adsorption component 120 is in contact with the circuit board body 110, at which time the first conductive part 131 and the second conductive part 132 are electrically connected through the conductive adsorption component 120 and generate a trigger signal, which is transmitted to the mainboard 230 of the electronic device 200 through the plug-in port 111, and the processor on the mainboard 230 analyzes and judges the placement state of the stylus 210. Moreover, the stylus detection structure 100 has a small volume and can be applied to different wide and narrow frames.

[0102] The electronic device 200 provided in the embodiment includes a device body 220, which includes a lower frame 221, and the lower frame 221 has a containing groove 222 with an opening facing away from the display surface, and the stylus detection structure 100 is arranged in the containing groove 222. Compared with the stylus detection structure 100 arranged in the lower frame 221, the stylus detection structure 100 of the application is not affected by the height of the inner cavity of the lower frame 221, and has a wider range of use.

[0103] The containing groove 222 has at least one connecting column 223, and the shell 140 of the stylus detection structure 100 is inserted on the connecting column 223 through the positioning hole 147, so as to preliminarily position the stylus detection structure 100 on the electronic device 200. The circuit board body 110 is bonded with the containing groove 222 to fix the stylus detection structure 100 on the electronic device 200. Thus, the screwless assembly can be realized, and the production line production is facilitated.

[0104] The lower frame 221 has a groove 224 on the side facing the display surface, and the inner surface of the groove 224 is arc-shaped, and the stylus 210 is placed in the groove 224. By arranging the groove 224, the stylus 210 can be closer to the stylus detection structure 100, thereby increasing the sensitivity of the stylus detection structure 100.

[0105] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the application, but not to limit them; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the application.
