[0043] As described in the background, the smart pen is a new type of writing tool that combines traditional writing functions with modern smart technology. In the related art, the smart pen includes a pen head and a pen body, and the pen head is mounted on the pen body. However, in order to realize the function of the smart pen, more functional components need to be provided on the smart pen, which increases the number of interactive keys and increases the difficulty of interaction in the process of human-computer interaction. In the process of pursuing function, the user's comfort and convenience are greatly reduced.

[0044] Reference Figures 1 to 7 In order to solve the above problems, according to one aspect of the present application, the embodiments of the present application provide a smart pen, which comprises a pen body 100 and a pen head 200, the pen head 200 is arranged at one end of the pen body 100; the end face of the pen body 100 away from the pen head 200 is provided with a containing groove 130; the smart pen further comprises a mounting piece 300, a pickup piece 400 and a control piece 500, wherein the mounting piece 300 comprises a mounting body 310 and an exposed body 320, the mounting body 310 is arranged in the containing groove 130, and the exposed body 320 is arranged on the mounting body 310 and located outside the containing groove 130; the pickup piece 400 is arranged on the exposed body 320; the control piece 500 is arranged in the containing groove 130 and is used for feeding back an instruction signal to a smart terminal; the control piece 500 is provided with a voice recognition module 520 which is electrically connected with the pickup piece 400.

[0045] In the embodiments of the present application, the containing groove 130 is a through groove arranged along the axial direction of the pen body 100, and the mounting body 310 can be fixedly installed in the containing groove 130 in a clamping mode, a plug-in mode, a screw connection mode, a welding mode or a gluing mode; meanwhile, the mounting piece 300 is an integrally formed piece, so as to facilitate manufacturing and processing; in other embodiments, the mounting body 310 and the exposed body 320 can also be two independent components which are connected with each other. The pickup piece 400 is a microphone which is used for picking up sound information; in other embodiments, the pickup piece 400 can also be a pickup or a pickup head. The control piece 500 comprises a control circuit board 510 and a voice recognition module 520, the voice recognition module 520 is fixedly installed on the control circuit board 510 and is electrically connected with the control circuit board 510. The smart terminal is a touch screen, and in other embodiments, the smart terminal can also be an infrared touch all-in-one machine, a smart blackboard, a tablet computer or a smart phone.

[0046] On the one hand, the voice recognition module 520 and the pickup piece 400 used in cooperation enable the smart pen to perform voice interaction with the smart terminal through voice instructions of a user, such as realizing functions of text input and editing, function calling and operation or content query and acquisition, thereby reducing the difficulty of human-computer interaction and improving the convenience and comfort of use.

[0047] In another aspect, by arranging the accommodating groove 130 on the end face of the pen body 100 away from the pen head 200, and mounting the mounting piece 300, the sound pickup piece 400 and the control piece 500 therein, the compactness and integration of the smart pen structure are realized; such a structural design does not affect the overall appearance of the smart pen and the comfort of handheld writing, and can cleverly integrate various functional components, facilitating the user to carry and use. Meanwhile, the sound pickup piece 400 is arranged on the exposed body 320, so that it can better receive external sound, avoiding the problem of poor sound pickup effect caused by being blocked by other components, and improving the sensitivity and accuracy of sound pickup.

[0048] Referring to Figures 4 to 8 In an embodiment, the exposed body 320 is provided with a mounting groove 321 on the end face away from the mounting body 310, and the sound pickup piece 400 is arranged in the mounting groove 321. The side surface of the exposed body 320 is provided with a sound transmission port 322 communicating with the mounting groove 321.

[0049] In the embodiment, the number of sound transmission ports 322 is multiple, and the multiple sound transmission ports 322 are arranged at intervals along the circumference of the exposed body 320.

[0050] On the one hand, the slot 321a of the mounting groove 321 and the sound transmission port 322 used in cooperation provide a transmission channel for sound, so that sound can be more efficiently transmitted from the outside to the sound pickup piece 400, reducing the attenuation and distortion of sound in the transmission process, and improving the success rate and fluency of voice interaction. On the other hand, the mounting groove 321 provides a certain protection for the sound pickup piece 400, reducing the opportunity for the sound pickup piece 400 to directly contact with external objects, reducing the risk of damage to the sound pickup piece 400 caused by collision, friction and other factors, and improving the service life and reliability of the sound pickup piece 400.

[0051] Referring to Figures 1 to 8 In an embodiment, the smart pen further comprises a protective cover 600 arranged on the pen body 100, the protective cover 600 encloses the exposed body 320, and the surface of the protective cover 600 is provided with sound transmission through holes 610 corresponding to the slot 321a of the mounting groove 321 and the sound transmission port 322.

[0052] In the embodiment, the protective cover 600 completely encloses the exposed body 320 and is fixedly mounted on the end face of the pen body 100 away from the pen head 200; the number of sound transmission through holes 610 is multiple, and the number of sound transmission through holes 610 is greater than or equal to the sum of the number of sound transmission ports 322 and the number of slots 321a of the mounting groove 321.

[0053] On the one hand, the protective cover 600 covers the exposed body 320, which can effectively prevent the pickup 400 from being damaged due to accidental collision, falling or friction with other objects, greatly reducing the risk of damage to the pickup 400, and effectively prolonging the service life of the smart pen. On the other hand, in combination with the sound transmission hole 610, the notch 321a of the mounting groove 321 and the sound transmission port 322, the sound can be guided and focused to a certain extent without affecting the transmission of sound, so that the external sound is more concentrated through the sound transmission hole 610 into the mounting groove 321 and reaches the pickup 400, further improving the accuracy and sensitivity of the pickup.

[0054] With reference to Figure 1 , Figure 2 and Figure 4 , in an embodiment, the smart pen further comprises a microphone cover 700, which is filled between the protective cover 600 and the exposed body 320 and covers the exposed body 320.

[0055] In this embodiment, the microphone cover 700 is a porous and breathable mesh structure; the microphone cover 700 is in close contact with the inner wall surface of the protective cover 600 and the outer surface of the exposed body 320, and the microphone cover 700 completely covers the exposed body 320.

[0056] The microphone cover 700 not only can absorb and isolate external noise, reduce environmental noise interference to the pickup 400, make the sound received by the pickup 400 clearer and purer, and improve the accuracy of voice recognition. At the same time, when the wind blows from the outside, the porous material or special structure in the microphone cover 700 can buffer and disperse the airflow, reduce the speed and impact force of the airflow, thereby reducing the noise generated by the airflow impacting the pickup 400, and further reducing the possibility of wind noise. In addition, the microphone cover 700 provides additional protection on the basis of the protective cover 600, further preventing dust, moisture, debris and other foreign matters from entering the mounting groove 321 and the sound transmission port 322 of the exposed body 320, avoiding damage to the pickup 400 by these foreign matters, and prolonging the service life of the pickup 400.

[0057] With reference to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8In an embodiment, the pickup 400 has a pickup end, which is arranged towards the slot opening 321a of the mounting groove 321. The above structure design allows the user to directly emit sound towards the slot opening 321a of the mounting groove 321, which can be accurately captured by the pickup 400. This not only improves the operability and convenience of use, but also reduces the reflection, refraction and scattering loss of sound in the propagation process, improves the receiving efficiency of sound, and ensures that the pickup 400 can capture sound signals more clearly and accurately.

[0058] With reference to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 In an embodiment, the exposed body 320 and the protective cover 600 are both triangular in cross section along the axis of the pen body 100, and the cross section of the protective cover 600 along the axis of the pen body 100 is the same as the shape of the end surface of the pen body 100 away from the pen tip 200.

[0059] In the present embodiment, the exposed body 320 and the protective cover 600 are both geometric bodies similar to triangular prisms, i.e., the cross section of the exposed body 320 and the protective cover 600 along the axis of the pen body 100 is an equilateral triangle, and the size remains unchanged throughout. The cross section of the protective cover 600 along the axis of the pen body 100 completely covers the cross section of the exposed body 320 along the axis of the pen body 100. The above structure design not only enhances the stability of the smart pen as a whole, but also improves the aesthetic appearance of the smart pen as a whole. In addition, the above structure design also reduces the mold cost and production difficulty, and improves the production efficiency.

[0060] With reference to Figures 1 to 8 In an embodiment, the pen tip 200 is a passive capacitive pen tip 200, and the pen tip 200 is electrically connected to the control member 500; the control member 500 further has a pressure sensing module 530, which is connected to the pen tip 200 and used to sense the pressure change generated by the pen tip 200.

[0062] The passive capacitive pen head 200 has high sensitivity, and is used in combination with the pressure sensing module 530 during writing, and through the application of different pressures, the line thickness and color depth can be changed; this structural design makes the writing experience more natural and smooth, effectively improving the use experience. At the same time, the pressure sensing module 530 is integrated on the control member 500 and connected with the pen head 200, and this compact design helps to realize the miniaturization and thinning of the smart pen under the premise of ensuring the function.

[0063] With reference to Figures 1 to 8 In an embodiment, the pen body 100 is provided with a magnetic attraction member for connecting with the smart terminal.

[0064] In the embodiment, the magnetic attraction member is a magnet, which is fixedly installed on the inner wall surface of the pen body 100; at the same time, the frame of the smart terminal is fixedly provided with a ferromagnetic metal component or a permanent magnet capable of generating magnetic attraction force with the magnetic attraction member, so that the smart pen can be stably adsorbed on the frame of the smart terminal; the above structural design effectively solves the problem of storing the smart pen, and reduces the possibility of losing the smart pen due to random placement.
