[0003] The purpose of this application is to provide a large touch screen and a large screen component, which aims to solve the technical problem in the related art that it is not easy to detect when a stylus stored in a storage slot is lost.

[0004] To achieve the above objectives, according to one aspect of this application, a large touchscreen is provided, including a large screen body and a detection mechanism for detecting the state of a stylus. The detection mechanism includes a storage component and a detection component. The storage component has a storage space, and the detection component includes a transmitting structure and a receiving structure disposed on the same side. The transmitting structure is used to transmit a detection signal toward the storage space, and the receiving structure is used to receive the detection signal. The stylus has a use state and a storage state. When the stylus is in the use state, the stylus is located outside the storage space, and the receiving structure receives a first detection signal. When the stylus is in the storage state, the stylus is stored in the storage space, and the receiving structure receives a second detection signal, which is different from the first signal.

[0005] Optionally, the testing mechanism also includes a control unit, with the transmitting structure and receiving structure disposed on the same side of the control unit and electrically connected to the control unit, and the control unit electrically connected to the main body of the large screen.

[0006] Optionally, the storage component is provided with a limiting space, and the control component passes through the limiting space; the inner wall of the limiting space is provided with two through holes leading into the storage space, and the transmitting structure and the receiving structure pass through the two through holes respectively; and / or, the control component is installed on the storage component by fasteners.

[0007] Optionally, the testing mechanism further includes a connector, which includes a detachably connected first connecting structure and a second connecting structure. One of the first connecting structure and the second connecting structure is disposed in the storage component, and the other is disposed in the stylus. When the stylus is in use, the first connecting structure and the second connecting structure are separated. When the stylus is in the storage component, the first connecting structure and the second connecting structure are connected.

[0008] Optionally, the first connecting structure and the second connecting structure are detachably connected by magnetic attraction; the first connecting structure is used to be disposed inside the stylus along the circumference of the stylus.

[0009] Optionally, the storage space is a storage groove, and the storage component has a storage surface, with the storage groove positioned on the storage surface along the length of the storage component.

[0010] Optionally, the storage component has a first side and a second side arranged opposite to each other along its own length, and the transmitting structure and the receiving structure are located on the first side or the second side simultaneously; and / or, the storage component has a mounting surface arranged opposite to the storage surface, and a mounting groove is provided on the mounting surface, and the second connecting structure is embedded in the mounting groove; the mounting surface is provided with a blocking structure, and the blocking structure prevents the second connecting structure from disengaging from the mounting groove by applying a blocking force to the second connecting structure.

[0011] Optionally, a limiting structure is provided within the storage space, and the limiting structure is provided with a limiting groove; when the stylus is in the stored state, the stylus is inserted into the limiting groove.

[0012] Optionally, the main body of the large screen is provided with a receiving groove, and the storage component is embedded in the receiving groove; and / or, the detection component is an ultrasonic detection component.

[0013] According to another aspect of this application, a large screen component is provided, including a stylus and the aforementioned large touch screen. The stylus has a use state and a storage state. When the stylus is in the use state, it is located outside the storage space, and the receiving structure receives a detection signal as a first signal. When the stylus is in the storage state, it is stored inside the storage space, and the receiving structure receives a detection signal as a second signal, which is different from the first signal.

[0014] The beneficial effects of the touchscreen provided in this application are as follows: By setting up a transmitting structure and a receiving structure, and utilizing the difference in the detection signal obtained by the receiving structure when the stylus is in use and in storage, this application can clearly distinguish whether the stylus is in storage. Specifically, when the stylus, which should be stored in the storage space, is removed from storage (i.e., lost), the detection signal of the receiving structure will change accordingly. The detection mechanism can trigger an alert mechanism based on this signal change, so that the user can know the status of the stylus in real time. The above structural design effectively reduces the risk of the stylus being lost from the storage space, ensuring the integrity and normal function of the touchscreen.

[0015] Furthermore, the transmitting and receiving structures are positioned on the same side. This design integrates the transmitting and receiving structures into the same area or location, avoiding the need to reserve installation positions on both sides and simplifying the structural design and manufacturing process of the storage components. Simultaneously, this same-side positioning eliminates the need for opposing side spaces in the storage area, allowing the transmitting and receiving structures to flexibly adapt to storage spaces of various shapes, effectively broadening their applicability.

The terminology used in this application is for the purpose of describing specific embodiments only and is not intended to limit the application. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] As described in the background section, large screens equipped with styluses typically include a storage unit with a slot for storing the stylus. However, once the stylus is stored in the slot, it is difficult to detect if it is lost.

[0040] Reference Figures 1 to 7 To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides a large touchscreen, which includes a large screen body 600 and a detection mechanism for detecting the state of a stylus 100. The detection mechanism includes a storage component 200 and a detection component 300. The storage component 200 has a storage space 211. The detection component 300 includes a transmitting structure 310 and a receiving structure 320 disposed on the same side. The transmitting structure 310 is used to transmit a detection signal toward the storage space 211, and the receiving structure 320 is used to receive the detection signal.

[0041] The stylus 100 has a use state and a storage state. When the stylus 100 is in use state, it is located outside the storage space 211, and the receiving structure 320 receives a detection signal as a first signal. When the stylus 100 is in storage state, it is stored inside the storage space 211, and the receiving structure 320 receives a detection signal as a second signal, which is different from the first signal.

[0042] In this embodiment, the detection mechanism can also be used in devices requiring touch functionality, such as tablet computers, electronic whiteboards, smart drawing boards, vehicle-mounted touch terminals, or industrial control panels. The storage component 200 is a storage block or shelf, and the storage space 211 is a storage groove. It can be understood that the storage space 211 can also be a storage hole, storage cavity, or storage position. The transmitting structure 310 is a transmitting probe, and the receiving structure 320 is a receiving probe. The detection signal emitted by the transmitting structure 310 into the storage space 211, after reaching the storage space 211, first contacts the inner wall surface of the storage space 211, then reflects towards the receiving structure 320, and is finally detected by the receiving structure 320. In this case, the propagation directions of the detection signal emitted by the transmitting structure 310 and the detection signal received by the receiving structure 320 intersect.

[0043] Furthermore, the transmitting structure 310 and the receiving structure 320 can be simultaneously disposed within the housing space 211, simultaneously disposed outside the housing space 211, or one disposed outside the housing space 211 and the other disposed within the housing space 211. The second signal differs from the first signal, which could mean that the strength, frequency, or propagation time of the second signal is different from the first signal; or it could mean that one of the first and second signals is a valid signal, and the other is a zero signal (i.e., a signal that does not exist or has no value). It is understood that the transmitting structure 310 and the receiving structure 320 can also be disposed on opposite sides (e.g., opposite to each other or adjacent to each other).

[0044] This application, by setting up a transmitting structure 310 and a receiving structure 320, utilizes the difference in detection signals obtained by the receiving structure 320 between the use state and the storage state of the stylus 100 to clearly distinguish whether the stylus 100 is in a storage state. Specifically, when the stylus 100, which should be stored in the storage space 211, is removed from the storage state (i.e., lost), the detection signal of the receiving structure 320 will change accordingly. The detection mechanism can trigger an alert mechanism based on this signal change, so that the user can know the status of the stylus 100 in real time. The above structural design effectively reduces the risk of the stylus 100 being lost from the storage space 211, ensuring the integrity of the touch screen and its normal use function.

[0045] Furthermore, the transmitting structure 310 and the receiving structure 320 are positioned on the same side. This structural design not only integrates the transmitting structure 310 and the receiving structure 320 into the same area or location, avoiding the need to reserve installation positions on both sides, but also simplifies the structural design and manufacturing process of the storage component 200. Simultaneously, the same-side positioning eliminates the need for opposing side spaces in the storage space 211, allowing the transmitting structure 310 and the receiving structure 320 to flexibly adapt to storage spaces 211 of various shapes, effectively broadening their applicability.

[0046] Reference Figure 2 , Figure 4 , Figure 7 as well as Figure 8 In one embodiment, the detection mechanism further includes a control unit 400, with the transmitting structure 310 and the receiving structure 320 disposed on the same side of the control unit 400 and electrically connected to the control unit 400. The control unit 400 is electrically connected to the main body 600 of the large screen.

[0047] In this embodiment, the control component 400 is a control circuit board, and the transmitting structure 310 and the receiving structure 320 are disposed on the same side and are both fixedly mounted on the control component 400.

[0048] The control unit 400 not only serves as a signal linkage mechanism but also supports and mounts the transmitting structure 310 and the receiving structure 320, thereby shortening the wiring length between the control unit 400, the transmitting structure 310, and the receiving structure 320. This structural design makes the detection mechanism more compact and integrated, saving overall space; it also optimizes the signal transmission path, reducing signal attenuation and interference during transmission, thus improving the accuracy and stability of the detection; furthermore, it effectively reduces production costs by reducing wiring materials and assembly processes.

[0049] Furthermore, this integrated design makes the transmitting structure 310, the receiving structure 320, and the control unit 400 a unified functional unit. When it is necessary to inspect or replace parts, the whole unit can be operated instead of checking the scattered components separately, which improves the convenience of later maintenance.

[0050] In addition, after the control unit 400 is electrically connected to the main body of the large screen 600, it can feed back information such as the storage status and usage status of the stylus 100 to the main body of the large screen 600 in real time (such as displaying prompts on the main body of the large screen 600 such as "stylus 100 has been stored" or "please put stylus 100 back"), thus realizing status linkage.

[0051] Reference Figures 7 to 9In one embodiment, the storage component 200 is provided with a limiting space 230, and the control component 400 passes through the limiting space 230; the inner wall of the limiting space 230 is provided with two connecting holes 240 that penetrate into the storage space 211, and the transmitting structure 310 and the receiving structure 320 respectively pass through the two connecting holes 240.

[0052] In this embodiment, the limiting space 230 is located on one side of the storage space 211, and can be a hollow limiting groove or a relatively closed limiting groove.

[0053] The limiting space 230 serves two purposes: firstly, it constrains the swaying of the control component 400, ensuring the stability of the control component 400 mounted on the storage component 200; secondly, it enables a nested assembly of the control component 400 and the storage component 200, making the overall structure of the detection mechanism more compact and further saving space. Simultaneously, the limiting space 230 also provides physical protection and signal isolation for the control component 400, extending its service life and reducing electromagnetic interference from external electromagnetic signals.

[0054] In addition, the connecting hole 240 not only provides directional guidance for the detection signal, reducing its diffusion to non-target areas and minimizing electromagnetic interference to other electronic components, but its structural design also helps to block external electromagnetic signals from affecting the transmitting structure 310 and the receiving structure 320, thereby improving the purity of the detection signal.

[0055] Reference Figure 2 , Figure 4 , Figure 7 as well as Figure 8 In one embodiment, the control element 400 is mounted on the receiving element 200 by fasteners.

[0056] In this embodiment, the fastener is a fastening screw or fastening bolt. The control component 400 is provided with a connecting through hole for the fastener to pass through, and the receiving component 200 is provided with a threaded hole for the fastener to pass through. It is understood that the fastener may also be a fastening pin.

[0057] The fasteners not only strengthen the connection between the control component 400 and the storage component 200, thereby improving the stability of the control component 400 installed on the storage component 200, but also facilitate the disassembly and assembly of the control component 400.

[0058] Reference Figure 4 , Figure 5 as well as Figure 8In one embodiment, the detection mechanism further includes a connector, which includes a first connecting structure 510 and a second connecting structure 520 that are detachably connected. One of the first connecting structure 510 and the second connecting structure 520 is disposed in the storage member 200, and the other is disposed in the stylus 100.

[0059] When the stylus 100 is in use, the first connecting structure 510 and the second connecting structure 520 are separated; when the stylus 100 is in storage, the first connecting structure 510 and the second connecting structure 520 are connected.

[0060] In this embodiment, the first connecting structure 510 and the second connecting structure 520 can be magnetic structures, snap-fit ​​structures, Velcro structures, concave-convex mating structures or electromagnetic adsorption structures used in conjunction.

[0061] The first connecting structure 510 and the second connecting structure 520, which are detachable, ensure the stability and security of the stylus 100 when it is in the storage state, preventing accidental detachment; and allow for unobstructed separation when the stylus 100 is switched to the use state, without affecting free access. This structural design effectively improves the convenience of storage and operation.

[0062] Meanwhile, the first connection structure 510 and the second connection structure 520 used in conjunction can also guide the stylus 100 to fall precisely into the preset position in the storage space 211, ensuring that the stylus 100 is exactly within the detection range of the transmitting structure 310 and the receiving structure 320 when in the storage state, reducing the risk of signal detection error caused by the placement deviation of the stylus 100 and improving the reliability of state detection.

[0063] Reference Figure 4 , Figure 5 as well as Figure 8 In one embodiment, the first connecting structure 510 and the second connecting structure 520 are detachably connected by magnetic attraction.

[0064] In this embodiment, one of the first connecting structure 510 and the second connecting structure 520 can be a structure made of a paramagnetic material, such as metals or alloys of iron, cobalt, and nickel, while the other is an object that is magnetic, such as a permanent magnet. Alternatively, both the first connecting structure 510 and the second connecting structure 520 can be objects that are magnetic, with opposite magnetic properties.

[0065] The magnetic attraction enables detachable connections, which not only makes connection and disassembly convenient but also ensures the reliability of the connection.

[0066] Reference Figure 4 , Figure 5 as well as Figure 8In one embodiment, the first connecting structure 510 is disposed inside the stylus 100 along the circumference of the stylus 100.

[0067] In this embodiment, the first connecting structure 510 is a 360° closed iron tube, and the length direction of the first connecting structure 510 is parallel to the axis of the stylus 100 to ensure the magnetic attraction effect; the second connecting structure 520 is disposed on the storage component 200 and is an object that is magnetic itself, such as a permanent magnet. It is understood that the first connecting structure 510 can also be a non-360° open tube, and the first connecting structure 510 can also be a tubular structure made of paramagnetic material, such as cobalt, nickel, or their alloys.

[0068] The first connecting structure 510 is arranged around the circumference of the stylus 100. This structural design allows the stylus 100 to be quickly attached to the second connecting structure 520 by means of a circumferential magnetic field, regardless of the circumferential angle at which it is placed in the storage space 211. This effectively improves the stability and reliability of the magnetic connection between the first connecting structure 510 and the second connecting structure 520.

[0069] Meanwhile, the first connecting structure 510 is built into the stylus 100, which eliminates the need for protrusions or exposed parts on the outer surface of the stylus 100, maintaining the simplicity of the stylus 100's appearance and the comfort of holding it; it also avoids direct friction between the first connecting structure 510 and external parts, extending the service life of the first connecting structure 510.

[0070] Reference Figure 2 , Figure 4 , Figure 6 as well as Figure 7 In one embodiment, the storage space 211 is a storage groove, and the storage component 200 has a storage surface 210. The storage groove is disposed on the storage surface 210 along the length direction of the storage component 200.

[0071] In this embodiment, when the stylus 100 is in the retracted state, the length direction of the stylus 100 is parallel to the length direction of the storage component 200, and the stylus 100 is completely located within the storage groove, thereby making the overall structure of the detection mechanism more compact. It can be understood that when the stylus 100 is in the retracted state, a portion of the stylus 100 may be located within the storage groove, while another portion may be located outside the storage groove. Furthermore, it can be understood that the storage groove may also be provided on the storage surface 210 along the width direction, thickness direction, or other directions of the storage component 200.

[0072] The stylus 100 is typically elongated, and the storage groove along the length of the storage component 200 naturally matches the shape of the stylus 100, allowing for a higher degree of contact between the stylus 100 and the inner wall of the storage groove after placement, thus reducing the risk of the stylus 100 wobbling. Simultaneously, the storage groove extending along the length of the storage component 200 also increases the contact area between the stylus 100 and the storage groove, further enhancing the stability of the stylus 100 in its stored state.

[0073] Reference Figure 2 , Figure 4 as well as Figures 6 to 8 In one embodiment, the receiving member 200 has a first side and a second side disposed opposite to each other along its own length direction, and the transmitting structure 310 and the receiving structure 320 are simultaneously located on the first side or the second side. It is understood that the receiving member 200 may also have other two sides disposed opposite to each other in other directions, and the transmitting structure 310 and the receiving structure 320 are simultaneously located on either of the other two sides.

[0074] The transmitting structure 310 and the receiving structure 320 are both located on the first or second side, enabling a precise fit between the propagation path of the detection signal and the stylus 100 in its stored state (a long strip-shaped form placed along the length of the storage component 200). The transmission angle, coverage area, and propagation direction of the detection signal are highly matched to the length direction of the stylus 100 and its placement within the storage space 211. This fit reduces the risk of signal attenuation and missed detections caused by misalignment between the detection signal path and the stylus 100's shape, thereby further improving the accuracy and precision of the detection.

[0075] Reference Figures 8 to 10 In one embodiment, the storage component 200 has a mounting surface 220 disposed opposite to the storage surface 210, and a mounting groove 221 is provided on the mounting surface 220. The second connecting structure 520 is embedded in the mounting groove 221. The mounting surface 220 is provided with a blocking structure 222, which blocks the second connecting structure 520 from disengaging from the mounting groove 221 by applying a blocking force to the second connecting structure 520.

[0076] In this embodiment, most of the second connecting structure 520 is embedded in the mounting groove 221 to make the overall structure of the detection mechanism more compact. The blocking structure 222 is a blocking hook. The hook portion 2221 of the blocking hook extends toward the side away from the mounting surface 220. The hook portion 2221 of the blocking hook has a hook surface 2222, which contacts the surface of the second connecting structure 520 away from the receiving surface 210 to prevent the second connecting structure 520 from detaching from the mounting groove 221. This structural design avoids the need for drilling or other treatments on the second connecting structure 520, ensuring the integrity of the second connecting structure 520.

[0077] Furthermore, to further reduce the overall size of the testing mechanism, a mounting groove 223 is provided on the mounting surface 220, and part of the barrier structure 222 is disposed within the mounting groove 223. Additionally, to reduce the impact of machining errors on the installation of the second connecting structure 520 into the mounting groove 221, and to improve the ease of installation and removal of the second connecting structure 520 within the mounting groove 221, multiple clearance grooves 224 are provided on the mounting surface 220, each corresponding to one of the corners of the mounting groove 221.

[0078] It is understood that the blocking structure 222 can also be a blocking screw. In this case, the second connecting structure 520 is provided with a connecting through hole for the blocking screw to pass through, and the bottom of the mounting groove 221 is provided with a threaded hole for the blocking screw to be screwed in and threadedly engaged with it. The blocking structure 222 can also be the inner wall surface of the mounting groove 221. Specifically, the second connecting structure 520 is interference-fitted into the mounting groove 221, and the inner wall surface of the mounting groove 221 applies a blocking force to the second connecting structure 520 by contacting it. The blocking structure 222 can also be a plug-in structure or a magnetic structure.

[0079] The mounting groove 221 and the barrier structure 222 used together ensure the stability of the second connecting structure 520 when it is installed on the storage component 200. At the same time, the mounting groove 221 also provides a wrap-around protection for the second connecting structure 520, reducing the direct damage to the second connecting structure 520 caused by external collisions and friction, and extending the service life of the second connecting structure 520.

[0080] Furthermore, to enhance the stability of the second connecting structure 520 within the mounting groove 221, multiple blocking structures 222 are provided, spaced circumferentially along the mounting groove 221. To ensure that the first connecting structure 510 and the second connecting structure 520 do not directly contact each other, the mounting groove 221 and the storage space 211 are two independent spaces, not interconnected. It is understood that if direct contact between the first connecting structure 510 and the second connecting structure 520 is required, the mounting groove 221 and the storage space 211 can also be interconnected, the connection depending on actual needs.

[0081] In addition, to enhance the stability of the stylus 100 in the storage space 211 when it is in the storage state, there are multiple second connecting structures 520, and the multiple second connecting structures 520 are spaced apart along the length direction of the storage component 200; the first connecting structure 510 is disposed inside the stylus 100 along the length direction of the stylus 100.

[0082] Reference Figures 2 to 5 In one embodiment, a limiting structure 250 is provided in the storage space 211, and the limiting structure 250 is provided with a limiting groove 251; when the stylus 100 is in the storage state, the stylus 100 is inserted into the limiting groove 251.

[0083] In this embodiment, the limiting structure 250 is a limiting protrusion, and the limiting structure 250 and the storage component 200 are integrally molded. In this case, the storage component 200 and the limiting structure 250 can both be elastic structures, such as silicone or foam, or both be rigid structures, such as metal or rigid plastic. It is understood that the limiting structure 250 can also be an elastic structure, such as silicone or foam, and the storage component 200 can be a rigid structure, such as metal or rigid plastic. The shape of the limiting groove 251 is adapted to the shape of the stylus 100.

[0084] The inner wall of the limiting groove 251 effectively constrains the stylus 100, limiting its movement, displacement, or rotation within the storage space 211, thus improving the stability of the stylus 100 in its stored state. Simultaneously, the limiting groove 251 guides the stylus 100 precisely into the detection range of the transmitting structure 310 and the receiving structure 320, ensuring that the relative position of the stylus 100 to the detection signal path is fixed in its stored state, thereby improving detection accuracy.

[0085] In addition, to further ensure the stability of the stylus 100 within the storage space 211, and to facilitate the removal of the stylus 100 from the limiting groove 251, there are multiple limiting structures 250, which are spaced apart along the length of the storage member 200. The number of limiting grooves 251 is the same as the number of limiting structures 250, and there is an operating gap between two adjacent limiting grooves 251.

[0086] Reference Figure 4 as well as Figures 6 to 8 In one embodiment, the detection element 300 is an ultrasonic detection component. In this embodiment, the transmitting structure 310 is used to transmit ultrasonic signals. It is understood that the detection element 300 may also be an infrared detection component, a laser detection component, or a radio frequency signal detection component.

[0087] Ultrasonic signals are insensitive to light and electromagnetic environments. Compared to infrared and photoelectric detection methods, they are less affected by internal electromagnetic radiation, strong external light (such as direct sunlight), or dust accumulation. Even if a small amount of dust or stains accumulate in the storage space 211, or if the surface of the stylus 100 is slightly worn, the ultrasonic waves can still propagate stably and be received, ensuring the reliability of detection in complex environments and reducing the risk of misjudgment due to environmental interference.

[0088] Meanwhile, ultrasonic detection can also calculate the distance between the stylus 100 and the detection component by measuring the round-trip time of the sound waves. This allows it to not only distinguish between the stylus 100's retracted state and its usage state, but also to further determine the degree of retraction of the stylus 100 (such as partially inserted or fully inserted). This granular function provides richer status feedback for the touchscreen (such as reminding the user that the stylus 100 is not fully retracted), which helps to achieve more refined status judgment.

[0089] Reference Figures 1 to 3 as well as Figure 11 In one embodiment, the large screen body 600 is provided with a receiving groove 611, and the storage component 200 is embedded in the receiving groove 611.

[0090] In this embodiment, the receiving groove 611 is disposed on the front surface 610 of the large screen body 600. The storage surface 210 corresponds to the opening of the receiving groove 611 (i.e., the front surface 610 of the large screen body 600), and the mounting surface 220 corresponds to the bottom of the receiving groove 611. It is understood that the receiving groove 611 can also be disposed on the side or back of the large screen body 600. The storage component 200 is installed onto the large screen body 600 and fixedly embedded in the receiving groove 611 using connecting screws. It is understood that the storage component 200 can also be fixedly embedded in the receiving groove 611 using connection structures such as snap-fit ​​structures, plug-in structures, welding structures, fusion structures, and magnetic structures, or it can be integrally formed with the large screen body 600. The storage component 200 is completely embedded in the receiving groove 611.

[0091] The storage component 200 is embedded in the receiving groove 611, realizing the embedded assembly of the testing mechanism and the main body of the large screen 600. This structural design not only helps to reduce the overall size of the touch screen, but also provides a wrap-around protection for the testing mechanism, extending its service life. In addition, it also improves the aesthetics of the testing mechanism.

[0092] Reference Figures 1 to 11 According to another aspect of this application, embodiments of this application also provide a large screen component, which includes a stylus 100 and the aforementioned large touch screen. The stylus 100 has a usage state and a storage state. When the stylus 100 is in the usage state, the stylus 100 is located outside the storage space 211, and the receiving structure 320 receives a detection signal as a first signal. When the stylus 100 is in the storage state, the stylus 100 is stored inside the storage space 211, and the receiving structure 320 receives a detection signal as a second signal, which is different from the first signal.

[0093] In summary, implementing the touch screen and screen components provided in this embodiment has at least the following beneficial technical effects: By setting up a transmitting structure 310 and a receiving structure 320, and utilizing the characteristic that the detection signal obtained by the receiving structure 320 differs between the use state and the storage state of the stylus 100, this application can clearly distinguish whether the stylus 100 is in a storage state. Specifically, when the stylus 100, which should be stored in the storage space 211, is removed from the storage state (i.e., lost), the detection signal of the receiving structure 320 will change accordingly. The detection mechanism can trigger an alert mechanism based on this signal change, so that the user can know the status of the stylus 100 in real time. The above structural design effectively reduces the risk of the stylus 100 being lost from the storage space 211, ensuring the integrity and normal use function of the touch screen.

[0094] Furthermore, the transmitting structure 310 and the receiving structure 320 are positioned on the same side. This structural design not only integrates the transmitting structure 310 and the receiving structure 320 into the same area or location, avoiding the need to reserve installation positions on both sides, but also simplifies the structural design and manufacturing process of the storage component 200. Simultaneously, the same-side positioning eliminates the need for opposing side spaces in the storage space 211, allowing the transmitting structure 310 and the receiving structure 320 to flexibly adapt to storage spaces 211 of various shapes, effectively broadening their applicability.

[0095] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. It should be noted that, for those skilled in the art, several equivalent obvious modifications and / or equivalent substitutions can be made without departing from the technical principles of this application, and these obvious modifications and / or equivalent substitutions should also be considered within the scope of protection of this application.
