[0036] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0037] As Figure 1 and Figure 2As shown, the multifunctional stylus 100 provided by the embodiment of the present disclosure comprises a pen body 101, a pen tip 103, a remote control function button 105 and a battery 106. The remote control chip 102 is arranged in the pen body 101. The pen tip 103 is arranged at the front end of the pen body 101, and the infrared emitter 104 electrically connected with the pen tip 103 is arranged on the pen tip 103. The pen tip 103 controls the infrared emitter 104 to emit the touch infrared light when the pen tip 103 is pressed. The remote control function button 105 is arranged on the pen body 101, and the remote control function button 105 is electrically connected with the infrared emitter 104 through the remote control chip 102. The remote control function button 105 controls the infrared emitter 104 to emit the remote control infrared light when the remote control function button 105 is operated. The battery 106 is arranged in the pen body 101, and one end of the battery 106 is connected with the pen tip 103 and the remote control function button 105, and the other end of the battery 106 is connected with the infrared emitter 104, so as to supply power for the infrared emitter 104.

[0038] Specifically, the pen body 101 is the main support structure of the whole multifunctional stylus 100, and the pen body 101 can provide the space for installing and fixing the components such as the pen tip 103, the remote control function button 105, the remote control chip 102 and the battery 106, so that these components can be integrated into the multifunctional stylus 100 with the touch function and the remote control function.

[0039] Specifically, the pen body 101 needs to have certain strength and stability to avoid damage of the components arranged in the pen body 101 when the components are subjected to external force. Specifically, the pen body 101 can be made of high-strength materials such as hard plastic or metal.

[0040] Specifically, in order to facilitate the user to touch or write on the target display device, the pen tip 103 is arranged at the front end of the pen body 101.

[0041] Specifically, the pen tip 103 is equivalent to an elastic reset switch, and the infrared emitter 104 electrically connected with the pen tip 103 is arranged on the pen tip 103. When the pen tip 103 is pressed, the elastic reset switch is closed to make the battery 106 supply power for the infrared emitter 104, so as to control the infrared emitter 104 to emit the touch infrared light.

[0042] Optionally, the pen tip 103 is a retractable pen tip 103. When the pen tip 103 is pressed, the pen tip 103 is retracted to make the battery 106 communicate with the infrared emitter 104, so as to emit the touch infrared light. When the pen tip 103 is not pressed, the pen tip 103 is extended to make the battery 106 disconnect with the infrared emitter 104.

[0043] Specifically, when the infrared emitter 104 emits the touch infrared light, the optical camera equipped on the display device of the conference display device (i.e. the target display device to be controlled by the multifunctional touch pen 100) can capture the touch infrared light appearing at the pen tip 103 and transmit it to the background algorithm board of the conference display device. The background algorithm realizes the positioning of the touch point by analyzing the position and change of the touch infrared light, thereby completing the touch operation such as writing and drawing.

[0044] Specifically, the remote control function keys 105 are used to control the movement and selection of the cursor on the target display device. The remote control function keys 105 include: cursor up and down remote control keys, cursor left and right remote control keys, confirmation keys and return keys.

[0045] Specifically, the remote control function keys 105 are arranged on the pen body 101 at a position convenient for the user to operate, so as to improve the convenience of user operation. The remote control function keys 105 are electrically connected to the infrared emitter 104 through the remote control chip 102, and the operation signal generated when the remote control function keys 105 are operated can be accurately controlled by the infrared emitter 104 after being processed by the remote control chip 102.

[0046] Specifically, when the user operates the remote control function keys 105, the keys will convert the user's operation into an electrical signal and transmit it to the remote control chip 102. The remote control chip 102 encodes and processes these signals according to the preset program, and then controls the infrared emitter 104 to emit the remote control infrared light.

[0047] Specifically, the remote control chip 102 is the core control component of the remote control function. By arranging the remote control chip 102 in the pen body 101, the remote control chip 102 can be protected, reducing the risk of damage to the remote control chip 102.

[0048] Specifically, the remote control chip 102 is used to receive the operation signal transmitted by the remote control function keys 105 and encode and process these signals. The remote control chip 102 can convert the user's key operation into a specific format of infrared remote control signal, so that the infrared emitter 104 can accurately emit the remote control instruction meeting the requirements of the device. The remote control chip 102 can also control the working state of the infrared emitter 104, such as the frequency, power and other parameters of the infrared light emitted by the infrared emitter 104.

[0049] Specifically, the infrared emitter 104 includes a touch working mode and a remote control working mode. In the touch working mode, when the pen tip 103 is pressed, the infrared emitter 104 is triggered to emit touch infrared light through the electrical connection between the pen tip 103 and the infrared emitter 104, for realizing the touch operation in a short distance. In the remote control working mode, the infrared emitter 104 is controlled to emit remote control infrared light according to the operation signal of the remote control function key 105, for realizing the remote control of the target display device.

[0050] Specifically, the battery 106 is used to supply power for the infrared emitter 104, so as to ensure the normal work of the infrared emitter 104. Meanwhile, it also provides necessary power support for the pen tip 103 and the remote control function key 105, so that these components can respond to the user's operation.

[0051] Optionally, the battery 106 can be a disposable battery 106 (for example, a dry battery 106) or a rechargeable battery 106 (for example, a lithium battery 106).

[0052] The multifunctional touch pen 100 provided by the embodiment of the present disclosure includes a pen body 101, a pen tip 103, a remote control function key 105 and a battery 106. The remote control chip 102 is arranged in the pen body 101, the pen tip 103 is arranged at the front end of the pen body 101, the infrared emitter 104 is arranged on the pen tip 103 and electrically connected with the pen tip 103, and the pen tip 103 controls the infrared emitter 104 to emit touch infrared light when the pen tip 103 is pressed. The remote control function key 105 is arranged on the pen body 101, and the remote control function key 105 is electrically connected with the infrared emitter 104 through the remote control chip 102. When the remote control function key 105 is operated, the infrared emitter 104 is controlled to emit remote control infrared light through the remote control chip 102. The battery 106 is arranged in the pen body 101, one end of the battery 106 is connected with the pen tip 103 and the remote control function key 105, and the other end of the battery 106 is connected with the infrared emitter 104, for supplying power for the infrared emitter 104. In this way, the infrared emitter 104 originally in the touch pen can make the touch pen have the remote control function, without integrating a Bluetooth module or a wireless communication module, and the remote control mode of the infrared radio frequency has lower delay than the signal transmission of Bluetooth or wireless. Therefore, the multifunctional touch pen 100 provided by the embodiment of the present disclosure can improve the response speed of the remote control function while considering the miniaturization of the touch pen.

[0053] As shown in FIG. 1, Figure 3 In some embodiments, the multifunctional touch pen 100 further includes a distance sensor 107. The pen tip 103 is electrically connected with the infrared emitter 104 through the distance sensor 107, and the distance sensor 107 is used to detect the current distance between the pen tip 103 and the target display device. In the case that the detected current distance is greater than a set distance, the distance sensor 107 disconnects the electrical connection between the pen tip 103 and the infrared emitter 104.

[0054] Specifically, by setting the distance sensor 107 and making the pen tip 103 electrically connected with the infrared emitter 104 through the distance sensor 107 instead of directly electrically connecting the pen tip 103 with the infrared emitter 104, the function implementation of the pen tip 103 is controlled by the distance sensor 107.

[0055] Specifically, by detecting the current distance between the pen tip 103 and the target display device, it can be determined whether the current distance between the pen tip 103 and the target display device is suitable for touch control. If the detected current distance is greater than the set distance, it indicates that the pen tip 103 cannot touch the target display device at this distance. Therefore, in this case, the distance sensor 107 will disconnect the electrical connection between the pen tip 103 and the infrared emitter 104, so that the infrared emitter 104 cannot emit touch infrared light, thereby avoiding false triggering of the touch control operation when the distance is too far. If the detected current distance is less than or equal to the set distance, it indicates that the pen tip 103 can touch the target display device at this distance. Therefore, in this case, the pen tip 103 can be allowed to control the infrared emitter 104 to emit touch infrared light when pressed, thereby realizing accurate close-range touch control function.

[0056] Optionally, the distance sensor 107 can use various technologies to measure the distance between the pen tip 103 and the target display device, such as ultrasonic technology or infrared reflection technology, etc. The present disclosure does not make specific limitations here.

[0057] In the present disclosure, by setting the distance sensor 107 capable of detecting the distance between the pen tip 103 and the target display device, and making the pen tip 103 electrically connected with the infrared emitter 104 through the distance sensor 107, false triggering of the touch control operation when the distance is too far can be avoided.

[0058] As shown in FIG. 1, Figure 4 In some embodiments, the multifunctional touch pen 100 further includes a laser conversion chip 108 and a laser key 109. The laser conversion chip 108 is arranged in the pen body 101. The laser key 109 is arranged in the pen body 101, and the laser key 109 is electrically connected with the infrared emitter 104 through the laser conversion chip 108. When the laser key 109 is operated, the infrared emitter 104 is controlled to emit indicating infrared light through the laser conversion chip 108, so as to indicate the content that the user wants to remotely mark on the target display device.

[0059] Specifically, the laser conversion chip 108 is the core control component of the laser indication function. By arranging the laser conversion chip 108 in the pen body 101, the laser conversion chip 108 can be protected, thereby reducing the risk of damage to the laser conversion chip 108.

[0060] Specifically, the laser key 109 is arranged on the pen body 101 at a position convenient for the user to operate, so as to improve the convenience of user operation. The laser key 109 is electrically connected to the infrared emitter 104 through the laser conversion chip 108, and the operation signal generated when the laser key 109 is operated can be processed by the laser conversion chip 108 to accurately control the operation of the infrared emitter 104.

[0061] Specifically, when the user operates the laser key 109, the key converts the operation into an electrical signal and transmits it to the laser conversion chip 108. The laser conversion chip 108 controls the infrared emitter 104 to emit an indicating infrared light according to the signal. The user can use the indicating infrared light to indicate the content that he or she wants to mark remotely by moving the stylus on the target display device, for example, indicating the key information that he or she wants to emphasize remotely in a meeting.

[0062] Optionally, the laser key 109 can be designed in various operation modes such as a press type and a touch type.

[0063] In the embodiments of the present disclosure, the laser conversion chip 108 is arranged in the pen body 101, the laser key 109 is arranged on the pen body 101, and the laser key 109 is electrically connected to the infrared emitter through the laser conversion chip 108, so that the multifunctional stylus 100 integrates the laser indicating function on the basis of integrating the touch function and the remote control function. In this way, the user's use experience can be further improved, and the application scenarios of the multifunctional stylus 100 are increased.

[0064] In some embodiments, the laser conversion chip 108 and the remote control chip 102 are integrated into one encoding chip.

[0065] Specifically, by integrating the laser conversion chip 108 and the remote control chip 102 into one encoding chip, compared with arranging independent laser conversion chips 108 and remote control chips 102, the space occupied in the pen body 101 is smaller. In this way, it is beneficial to further miniaturize the multifunctional stylus 100.

[0066] In some embodiments, the pen body 101 is internally provided with a plurality of accommodating cavities, the plurality of accommodating cavities are separated by insulating partitions, and the plurality of accommodating cavities are respectively used to place the remote control chip 102, the laser conversion chip 108 and the battery 106.

[0067] It is understandable that the chip and battery 106 generate different electrical signals and currents during operation. Direct contact between them could lead to short circuits or damage to the remote control chip 102 or the laser conversion chip 108. Therefore, this embodiment uses insulating partitions to isolate multiple cavities within the pen body 101, placing the battery 106, remote control chip 102, and laser conversion chip in different cavities. This reduces interference between different components and improves the safety and reliability of the multi-functional stylus pen 100.

[0068] like Figure 5 As shown, in some embodiments, when the battery 106 is a rechargeable battery 106, the multi-functional stylus 100 further includes a charging port 110. The charging port 110 is disposed on the pen body 101 and is electrically connected to the charging input terminal of the battery 106.

[0069] Specifically, when the battery 106 is a rechargeable battery 106, it is very inconvenient to remove the battery 106 from the pen body 101 for charging. Therefore, in this embodiment of the present disclosure, a charging port 110 electrically connected to the charging input terminal of the battery 106 is provided on the pen body 101.

[0070] Optionally, the charging port 110 is located at the rear end of the pen body 101.

[0071] In some embodiments, the pen body 101 has a magnetic attraction function.

[0072] Specifically, the pen body 101 can be made directly using magnetic materials (e.g., permanent magnet materials such as ferrite and neodymium iron boron) to give it a magnetic attraction function. Alternatively, magnetic elements (e.g., magnets) can be added inside or to the surface of the pen body 101 to give it a magnetic attraction function.

[0073] Specifically, by giving the pen body 101 a magnetic function, the multi-functional stylus 100 can be magnetically attached to the target display device when not in use, preventing the multi-functional stylus 100 from being lost and making it convenient for users to access at any time.

[0074] In some embodiments, the pen body 101 is provided with an anti-slip texture.

[0075] Specifically, by setting anti-slip texture on the pen body 101, the risk of the multi-functional stylus 100 accidentally slipping from the user's hand during use can be effectively reduced.

[0076] In some embodiments, the conference display device includes a display device and a multi-functional stylus as described above. The display device has touch and remote control capabilities. The multi-functional stylus as described above can be used to control the display device via touch or remote control.
