[0045] The terms "first", "second", "third" (if any) in the description, claims, and drawings of the present application are used to distinguish similar objects, and do not necessarily have to describe a particular order or sequence.

[0047] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0048] The existing touch display terminal has a magnet and a magnetic sensor arranged in the frame to detect the state of the stylus. The stylus can be adsorbed on the frame by the magnet, and the user picks up the stylus when using it. In this way, when the stylus is close to and away from the magnet, the magnetic sensor will detect the change of the magnetic field emitted by the magnet, so as to judge the state of the stylus. However, there are many metal parts around the magnet, such as the back shell, so the magnetic field of the magnet is easily disturbed by other metal parts, which finally leads to inaccurate data read by the magnetic sensor, and even causes the function to fail when the interference is large.
[0049] In order to solve the above technical problems, the application provides a pen lifting detection assembly and an interactive smart panel.
[0050] Figure 1 The application provides a structural schematic diagram of the interactive smart panel. Figure 1 As shown in the figure, the application provides an interactive smart panel, which comprises a frame 100, a display module 200, a stylus 300 and a pen lifting detection assembly 400.
[0051] The frame 100 is arranged around the periphery of the display module 200, the pen lifting detection assembly 400 is connected with the frame 100, and the pen lifting detection assembly 400 is at least partially located in the frame 100.
[0052] When the stylus 300 is in the storage state, the stylus 300 is placed on the frame 100.
[0053] In the specific implementation, part of the stylus 300 is made of metal, and the stylus 300 is adsorbed on the frame 100 by the magnetic element in the pen lifting detection assembly 400. The pen lifting detection assembly 400 is arranged on the lower frame.
[0054] When a user uses the stylus 300, the pen lifting detection assembly 400 detects that the stylus 300 is in the pen lifting state, and the interactive smart panel automatically responds. Since the interactive smart panel can automatically respond, the operation of calling functions after the stylus is lifted by the user can be reduced, and the user experience can be improved.
[0055] For example, when the pen lifting detection assembly 400 detects that the stylus 300 is in the pen lifting state, the response of the interactive smart panel is to automatically start the writing function. After the user takes the stylus 300, the user can perform writing operations such as line drawing, character writing and picture drawing on the interactive smart panel by using the stylus. The response mode of the interactive smart panel is not limited in the embodiment.
[0056] It should be noted that the interactive smart panel is an integrated device for controlling and realizing man-machine interactive operation on the content displayed on the display panel (display screen) through touch technology. The interactive smart panel is widely used in the fields of education and teaching, enterprise conference and commercial display, and can effectively improve the communication environment and improve the group communication efficiency.
[0057] It can be understood that the structure shown in the embodiment does not constitute a specific limitation on the interactive smart tablet. In other embodiments of the present application, the interactive smart tablet can include more or fewer components than shown, or combine certain components, or split certain components, or different component arrangements. For example, the interactive smart tablet can also include a pickup assembly, a speaker, and the like.
[0058] Figure 2 A structure diagram of a pen detection assembly provided in an interactive smart tablet according to an embodiment of the present application is shown in Figure 3 A structure diagram of a pen detection assembly provided in an interactive smart tablet according to an embodiment of the present application is shown in Figure 4 A structure diagram of a pen detection assembly provided in an interactive smart tablet according to an embodiment of the present application is shown in Figure 5 A structure diagram of a pen detection assembly provided in an interactive smart tablet according to an embodiment of the present application is shown in
[0059] Referring to Figures 2 to 5 The pen detection assembly 400 provided in the present application includes a bracket 410, a magnetic member 420, and a conducting member 430.
[0060] The bracket 410 has a first accommodating cavity 411 therein, and the first accommodating cavity 411 has at least one elastic support portion 412 therein. The bracket 410 has a conductive portion 413 thereon, and the conductive portion 413 is partially located in the first accommodating cavity 411.
[0061] The magnetic member 420 is located in the first accommodating cavity 411, and the elastic support portion 412 and part of the inner side wall of the first accommodating cavity 411 jointly support the magnetic member 420. The magnetic member 420 can attract an accessory.
[0062] The conducting member 430 has a positive electrode 432 and a negative electrode 431. One of the positive electrode 432 and the negative electrode 431 is electrically connected to the side of the conductive portion 413 away from the magnetic member 420, and the other is electrically connected to the side of the magnetic member 420 away from the conductive portion 413.
[0063] When the accessory is close to the magnetic member 420, the magnetic member 420 drives the elastic support portion 412 to compress, and the magnetic member 420 contacts the conductive portion 413, so that the positive electrode 432 and the negative electrode 431 are in communication with the conductive portion 413 through the magnetic member 420.
[0064] It should be noted that the accessory is the stylus 300.
[0065] Referring to Figure 4 and Figure 5As shown, when the stylus 300 is in the storage state, the attraction force between the stylus 300 and the magnetic member 420 causes the elastic support part 412 to be compressed, the magnetic member 420 moves downward to contact the conductive part 413, thereby causing the positive pole 432 and the negative pole 431 to be in communication, triggering the pen-up signal. When the stylus 300 is in the pen-up state, the elastic support part 412 loses the attraction force between the stylus 300 and the magnetic member 420, the elastic support part 412 restores under the action of its own elastic force, the magnetic member 420 moves upward, the magnetic member 420 has a spacing with the conductive part 413, and the positive pole 432 and the negative pole 431 are disconnected.
[0066] The magnetic member 420 is a magnet.
[0067] The bracket 410 is made of two materials, one is an insulating soft rubber material used to form a structure except the conductive part 413, and the other is a soft rubber material with conductive additives used to form the conductive part 413. The bracket 410 is processed by double-color co-extrusion.
[0068] The pen-up detection assembly 400 provided by the embodiment is provided by setting the bracket 410, the magnetic member 420, and the conductive member 430. The bracket 410 has a first accommodating cavity 411 therein, the first accommodating cavity 411 has an elastic support part 412 therein, the bracket 410 has a conductive part 413 thereon, and the conductive part 413 is partially located in the first accommodating cavity 411. The magnetic member 420 is located in the first accommodating cavity 411, and the elastic support part 412 and part of the inner side wall of the first accommodating cavity 411 jointly support the magnetic member 420, and the magnetic member 420 can adsorb the adsorption member. The conductive member 430 has a positive pole 432 and a negative pole 431, one of the positive pole 432 and the negative pole 431 is electrically connected to the side of the conductive part 413 away from the magnetic member 420, and the other is electrically connected to the side of the magnetic member 420 away from the conductive part 413. When the adsorption member is close to the magnetic member 420, that is, when the adsorption member is in the storage state, the attraction force between the magnetic member 420 and the adsorption member causes the elastic support part 412 to be compressed, the magnetic member 420 moves towards the conductive part 413 until the magnetic member 420 contacts the conductive part 413, causing the positive pole 432 and the negative pole 431 to be in communication through the magnetic member 420 and the conductive part 413. When the adsorption member is away from the magnetic member 420, that is, when the adsorption member is in the pen-up state, the elastic support part 412 restores under the action of its own elastic force, the magnetic member 420 moves upward, the magnetic member 420 has a spacing with the conductive part 413, and the positive pole 432 and the negative pole 431 are disconnected. The state of the adsorption member can be detected by the positive pole 432 and the negative pole 431 being in communication or being disconnected, which is not affected by external electromagnetic interference and has high detection accuracy.
[0069] In order to improve the supporting effect of the elastic support part 412 on the magnetic member 420, the number of the elastic support part 412 is at least two, and each conductive part 413 is located on the two sides of the conductive part 413.
[0070] In a specific implementation, the elastic support part 412 is an elastic arm.
[0071] In some embodiments, the elastic support part 412 can be an insulating spring.
[0072] Figure 6 A structural schematic diagram of a conducting member in a pen lifting detection assembly provided by an embodiment of the application, Figure 7 An internal structural schematic diagram of a conducting member in a pen lifting detection assembly provided by an embodiment of the application.
[0073] Referring to Figure 6 and Figure 7 As shown, the conducting member 430 further includes a conducting member body 433, the negative pole 431 includes a first copper leakage part 4311 and a first wire 4312 connected with the first copper leakage part 4311, and the positive pole 432 includes a second copper leakage part 4321 and a second wire 4322 connected with the second copper leakage part 4321.
[0074] The first copper leakage part 4311 and the second copper leakage part 4321 are both connected with the conducting member body 433, and the first wire 4312 and the second wire 4322 are located in the conducting member body 433.
[0075] Among the first copper leakage part 4311 and the second copper leakage part 4321, one is electrically connected with a side of the conductive part 413 facing away from the magnetic member, and the other is electrically connected with a side of the magnetic member 420 facing away from the conductive part 413.
[0076] It can be understood that, by arranging the first copper leakage part 4311 and the second copper leakage part 4321, the contact area of the conducting member 430 with the magnetic member 420 and the conductive part 413 can be increased, thereby improving the connection reliability of the electrical connection between the conducting member 430 and the magnetic member 420 and the electrical connection between the conducting member 430 and the conductive part 413.
[0077] Among the first copper leakage part 4311 and the second copper leakage part 4321, one is electrically connected with a side of the conductive part 413 facing away from the magnetic member, and the other is electrically connected with a side of the magnetic member 420 facing away from the conductive part 413.
[0078] In a possible implementation, the conducting member body 433 has a first connection end 4331 and a second connection end 4332, the first copper leakage part 4311 is connected with the first connection end 4331, and the second copper leakage part 4321 is connected with the second connection end 4332.
[0079] It can be understood that, by setting the first connecting end 4331 and the second connecting end 4332, the first copper leakage part 4311 and the second copper leakage part 4321 are arranged at an angle with the body 433 of the conducting piece, which facilitates the installation of the conducting piece 430.
[0080] In a specific implementation, the conducting piece 430 is a flexible circuit board.
[0081] The flexible circuit board is light in weight and thin in thickness, which facilitates the realization of the light and compact overall structure of the pen-up detection assembly 400.
[0082] Figure 8 For Figure 5 The local enlargement at A in FIG. 4B. Referring to FIG. 4B, in some embodiments, the first copper leakage part 4311 is attached to the side of the magnetic piece 420 away from the conductive part 413 by means of conductive double-sided adhesive, the second copper leakage part 4321 covers the side of the conductive part 413 away from the magnetic piece 420 and part of the bracket 410, and the conductive part 413 and part of the bracket 410 are attached to the second copper leakage part 4321 by means of conductive double-sided adhesive. Figure 8
[0083] The conductive double-sided adhesive is used to realize the electrical connection between the first copper leakage part 4311 and the magnetic piece 420 and the electrical connection between the second copper leakage part 4321 and the conductive part 413, which facilitates the operation and is high in reliability.
[0084] Please continue to refer to Figure 2 and Figure 3 As shown in FIG. 4B, the frame 100 has a second accommodating cavity 110 therein, the frame 100 has an opening 120 communicating with the second accommodating cavity 110, the pen-up detection assembly 400 is partially inserted into the second accommodating cavity 110 through the opening 120, and the second copper leakage part 4321 of the pen-up detection assembly 400 is connected to the bottom wall of the second accommodating cavity 110.
[0085] In this case, the second copper leakage part 4321 is connected to the bottom wall of the second accommodating cavity 110 by means of insulating double-sided adhesive. The pen-up detection assembly 400 is assembled without using screw assemblies, and the pen-up detection assembly 400 is installed in the frame 100, which facilitates the production.
[0086] It can be understood that, by arranging the pen-up detection assembly 400 in the frame 100, the overall structure of the interactive smart tablet is compact.
[0087] In a possible implementation, the side of the bracket 410 of the pen-up detection assembly 400 away from the bottom wall of the second accommodating cavity 110 has a holding part 414, and the holding part 414 is at least partially located outside the second accommodating cavity 110.
[0088] When the pen lifting detection assembly 400 is disassembled, the pen lifting detection assembly 400 can be separated from the frame 100 by pulling the holding portion 414. In this way, the operation is facilitated, and the disassembly efficiency is improved.
[0089] Please continue to see Figure 4 and Figure 5 As shown, at least one side wall of the bracket 410 of the pen lifting detection assembly 400 is inclined to make the size of the part of the bracket 410 located in the second accommodating cavity 110 smaller than the size of the part of the bracket 410 located outside the second accommodating cavity 110.
[0090] The outer side wall of the bracket 410 abuts against the opening 120.
[0091] Specifically, as shown in Figure 4 and Figure 5 The left and right side walls of the bracket 410 are inclined.
[0092] It can be understood that the inclination of the bracket 410 facilitates the installation of the pen lifting detection assembly 400 on the frame 100. Moreover, the outer side wall of the bracket 410 is in interference fit with the opening 120, and the opening 120 extrudes the outer side wall of the bracket 410, which can ensure that the pen lifting detection assembly 400 is installed firmly and is not prone to shaking.
[0093] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it 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 present application.
