Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a dictionary pen. Background Technology

[0002] Based on optical symbol recognition technology and an embedded translation system, the dictionary pen replaces the button input of traditional electronic dictionaries with a high-speed scanning method for looking up words. To look up unfamiliar words, simply scan lightly, and the pressure-sensitive module of the dictionary pen will trigger the scanning component to start the scanning function when pressed. The dictionary pen can then explain and pronounce the words based on the scanned content.

[0003] Most existing dictionary pens have a retractable foot at the end of the pen casing. In the non-working state, the foot extends out of the casing. In the working state, when the dictionary pen is pressed and slid across a scanning medium such as paper or a screen, the foot contacts the surface of the medium and retracts into the casing under pressure, triggering a pressure-sensitive switch installed inside the casing to activate the scanning function. This triggering scheme is a mechanical design, which is susceptible to mechanical fatigue and wear. With increased use, the sensitivity of the trigger decreases rapidly, limiting the pen's lifespan. Utility Model Content

[0004] This invention provides a dictionary pen to solve the problems of large mechanical fatigue wear and poor reliability in the trigger design of existing dictionary pens.

[0005] This utility model provides a dictionary pen, comprising: A pen casing having a receiving cavity and an opening communicating with the receiving cavity, the opening being located at the scanning end of the pen casing; A pressure-sensitive assembly is disposed in the receiving cavity and includes a wear-resistant component, a pressure-sensitive bracket, and a pressure-sensitive element. The pressure-sensitive bracket includes a fixed part and an overlapping part connected to each other. The fixed part is connected to the pen shell, and the overlapping part is connected to the wear-resistant component. The wear-resistant component extends out of the pen shell through the opening, and at least a portion of the pressure-sensitive element is disposed in the overlapping part. When the wear-resistant part is subjected to pressure, it drives the overlapping part to bend toward the fixed part, and the overlapping part causes the pressure-sensitive element to deform so that the pressure-sensitive element generates a pressure signal.

[0006] According to the dictionary pen of this utility model, the fixing part and the overlapping part are connected at the middle, and the overlapping part and the wear-resistant part are arranged side by side; The first end of the wear-resistant part is provided with a first protrusion, which is connected to the first end of the overlapping part. The second end of the wear-resistant part is provided with a second protrusion, which is connected to the second end of the overlapping part.

[0007] According to the dictionary pen of this utility model, the first protrusion and the second protrusion reserve a receiving gap between the wear-resistant part and the overlapping part, and the pressure-sensitive element is disposed in the receiving gap.

[0008] According to the dictionary pen of this invention, the pressure-sensitive element includes: A flexible circuit board is disposed on the side of the overlapping portion facing the wear-resistant component; A varistor is disposed on the side of the flexible circuit board away from the overlapping portion. The varistor is spaced apart from the wear-resistant component and is electrically connected to the flexible circuit board.

[0009] According to the dictionary pen of this utility model, the pressure-sensitive component further includes: a reinforcing plate disposed on one side of the overlapping portion facing the wear-resistant part, and the pressure-sensitive element disposed on one side of the reinforcing plate away from the overlapping portion; The wear-resistant component is connected to the first end of the reinforcing plate via the first protrusion and to the second end of the reinforcing plate via the second protrusion.

[0010] According to the dictionary pen of this utility model, the first end of the overlapping part is provided with a first hook, and the second end of the overlapping part is provided with a second hook; A portion of the first protrusion protrudes from the first end of the wear-resistant component and is hooked into the first hook, and a portion of the second protrusion protrudes from the second end of the wear-resistant component and is hooked into the second hook.

[0011] According to the dictionary pen of this utility model, the wear-resistant component extends along the width direction of the pen shell, and the shape of the opening is adapted to the wear-resistant component.

[0012] According to the dictionary pen of this utility model, the pen shell is provided with a scanning window, and the scanning window is disposed close to the scanning end; The dictionary pen further includes: a scanning component disposed in the receiving cavity and facing the scanning window, the scanning component and the pressure-sensitive component being electrically connected; The scanning component is used to scan the content to be scanned as framed by the scanning window.

[0013] According to the dictionary pen of this utility model, the dictionary pen further includes: A full-screen display is located on the front of the pen casing. The full-screen display includes a first display area for displaying the content to be scanned. The back of the pen casing is provided with a groove, which forms the scanning window.

[0014] According to the dictionary pen of this utility model, the scanning component includes: A camera, used to capture the content to be scanned as framed by the scanning window; A fill light, which is used to provide supplementary lighting for the camera's shooting.

[0015] This invention relates to a dictionary pen. An opening is provided at the scanning end of the pen casing to house a wear-resistant component. A portion of this component extends out of the casing and is compressed by the scanning medium during scanning. This pressure is transmitted to the overlapping portion of the pressure-sensitive support, causing the overlapping portion to bend and deform towards the fixed portion. This, in turn, causes the pressure-sensitive element in contact with the overlapping portion to deform synchronously. The pressure-sensitive element generates a pressure signal when the contact portion deforms, which triggers the dictionary pen's scanning function. Therefore, this invention primarily uses the pressure signal generated by the deformation of the pressure-sensitive element to trigger the scanning function. During the triggering process, the wear-resistant component, the overlapping portion, and the pressure-sensitive element only undergo minor deformations or displacements, resulting in minimal mechanical fatigue wear between the components. This effectively solves the problem of significant mechanical fatigue wear and poor reliability in the triggering design of existing dictionary pens. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] The following is combined Figures 1-11 The dictionary pen provided by the utility model embodiment will be described in detail through specific embodiments and application scenarios.

[0031] like Figure 1 and Figure 2As shown, this embodiment provides a dictionary pen, including: a pen shell 1 and a pressure-sensitive component 2. The pen shell 1 has a receiving cavity and an opening communicating with the receiving cavity, the opening being located at the scanning end of the pen shell 1; the pressure-sensitive component 2 is disposed in the receiving cavity and includes a wear-resistant part 21, a pressure-sensitive bracket 22, and a pressure-sensitive element 23. The pressure-sensitive bracket 22 includes a fixed part 221 and an overlapping part 222 connected to each other. The fixed part 221 is connected to the pen shell 1, and the overlapping part 222 is connected to the wear-resistant part 21. The wear-resistant part 21 extends out of the pen shell 1 through the opening, and at least a portion of the pressure-sensitive element 23 is disposed in the overlapping part 222; wherein, when the wear-resistant part 21 is pressed, it drives the overlapping part 222 to bend toward the fixed part 221, and the overlapping part 222 causes the pressure-sensitive element 23 to deform, so that the pressure-sensitive element 23 generates a pressure signal.

[0032] In this embodiment, the pen shell 1 is used to install other components of the dictionary pen. The pen shell 1 has a receiving cavity, and the scanning end of the pen shell 1 has an opening that communicates with the receiving cavity. It can be understood that the scanning end is the end of the dictionary pen used to align with the content to be scanned when scanning. The receiving cavity is used to house the pressure-sensitive component 2. The pressure-sensitive component 2 is used to generate a pressure-sensitive signal when scanning. The pressure-sensitive signal can be used to trigger the scanning function of the dictionary pen so as to scan the content to be scanned.

[0033] Specifically, a portion of the wear-resistant component 21 of the pressure-sensitive assembly 2 is located within the receiving cavity, while a portion extends beyond the pen housing 1 to contact the surface of the scanning medium during scanning. The wear-resistant component 21 can be made of a wear-resistant material, or its surface can be coated with a self-lubricating coating to reduce wear between the wear-resistant component 21 and the scanning medium, and between the wear-resistant component 21 and the inner wall of the pen housing 1, thereby extending its service life. The scanning medium can be a planar medium capable of displaying text and images, such as paper or a screen.

[0034] The wear-resistant part 21, located within the receiving cavity, is connected to the overlapping portion 222 of the pressure-sensitive bracket 22. During scanning, the wear-resistant part 21 contacts the surface of the scanning medium. Under pressure from the scanning medium, it transmits pressure to the overlapping portion 222. The overlapping portion 222 is connected to the fixing portion 221, which is fixed by the pen shell 1. This causes the overlapping portion 222 to bend and deform towards the fixing portion 221 under pressure. At least a portion of the pressure-sensitive element 23 is disposed in the overlapping portion 222. When the overlapping portion 222 bends and deforms, the contact portion between the pressure-sensitive element 23 and the overlapping portion 222 deforms synchronously with the overlapping portion 222. The pressure-sensitive element 23 generates a pressure signal after the contact portion deforms. It is understood that the pressure signal from the pressure-sensitive element 23 can be transmitted to the dictionary pen's control system (such as the motherboard). Upon receiving the corresponding pressure signal, the control system controls the dictionary pen to start the scanning function.

[0035] The dictionary pen of this invention has an opening at the scanning end of the pen shell 1. The opening is used to house a wear-resistant part 21. Part of the wear-resistant part 21 extends out of the pen shell 1 and is compressed by the scanning medium during scanning. The pressure is transmitted to the overlapping part 222 of the pressure-sensitive bracket 22, causing the overlapping part 222 to bend and deform towards the fixing part 221. This causes the pressure-sensitive element 23 to deform synchronously with the part in contact with the overlapping part 222. The pressure-sensitive element 23 can generate a corresponding pressure-sensitive signal according to the deformation of the deformed part. The pressure-sensitive signal is used to trigger the scanning function of the dictionary pen.

[0036] As can be seen from the above, the dictionary pen of this utility model mainly triggers the scanning function of the dictionary pen by the pressure signal generated after the deformation of the pressure-sensitive element 23. During the triggering process, the wear-resistant part 21, the overlapping part 222 and the pressure-sensitive element 23 will only undergo slight deformation or displacement. The mechanical fatigue wear between the components is small, which effectively solves the problem of large mechanical fatigue wear and poor reliability in the triggering design of the dictionary pen in the prior art.

[0037] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the middle part of the fixing part 221 and the overlapping part 222 are connected, and the overlapping part 222 and the wear-resistant part 21 are arranged side by side; the first end of the wear-resistant part 21 is provided with a first protrusion 211, which is connected to the first end of the overlapping part 222, and the second end of the wear-resistant part 21 is provided with a second protrusion 212, which is connected to the second end of the overlapping part 222.

[0038] In this embodiment, by connecting the middle part of the overlapping part 222 to the fixing part 221, the part where the overlapping part 222 and the fixing part 221 are connected is supported and fixed by the fixing part 221, while the two ends of the overlapping part 222 are suspended, so that the two ends of the overlapping part 222 can be bent and deformed relative to the middle part of the overlapping part 222. Meanwhile, by arranging the wear-resistant part 21 and the overlapping part 222 side by side, the first end of the wear-resistant part 21 and the first end of the overlapping part 222 are arranged opposite each other, and the second end of the wear-resistant part 21 and the second end of the overlapping part 222 are arranged opposite each other. The first end of the wear-resistant part 21 is provided with a first protrusion 211 that protrudes toward the overlapping part 222 and is connected to the first end of the overlapping part 222, and the second end of the wear-resistant part 21 is provided with a second protrusion 212 that protrudes toward the overlapping part 222 and is connected to the second end of the overlapping part 222. When the wear-resistant part 21 is pressed, the first protrusion 211 and the second protrusion 212 can respectively press the first end and the second end of the overlapping part 222, causing the first end and the second end of the overlapping part 222 to bend and deform relative to the middle of the overlapping part 222, thereby deforming the pressure-sensitive element 23 that is in contact with the overlapping part 222 and generating a corresponding pressure-sensitive signal.

[0039] In some embodiments, such as Figure 3 and Figure 4 As shown, the first protrusion 211 and the second protrusion 212 leave a receiving gap between the wear-resistant part 21 and the overlapping part 222, and the pressure-sensitive element 23 is disposed in the receiving gap.

[0040] In this embodiment, the first protrusion 211 and the second protrusion 212 protrude toward the overlapping portion 222 relative to the middle of the wear-resistant part 21, and are respectively connected to the first end and the second end of the overlapping portion 222, so that there is a certain gap between the middle of the wear-resistant part 21 and the overlapping portion 222, thereby leaving a certain accommodating gap between the wear-resistant part 21 and the overlapping portion 222. The accommodating gap is used to accommodate the pressure-sensitive element 23, so as to avoid the wear-resistant part 21 directly pressing the pressure-sensitive element 23 when it is under pressure, which would cause damage to the pressure-sensitive element 23.

[0041] Alternatively, in some embodiments, such as Figure 4 As shown, the wear-resistant part 21 is provided with a relief groove 213 at the position corresponding to the pressure-sensitive element 23, so as to prevent the wear-resistant part 21 from directly pressing the pressure-sensitive element 23 when it is under pressure.

[0042] In some embodiments, such as Figure 4 and Figure 5 As shown, the pressure-sensitive element 23 includes a flexible circuit board 231 and a varistor 232. The flexible circuit board 231 is disposed on the side of the overlap portion 222 facing the wear-resistant member 21; the varistor 232 is disposed on the side of the flexible circuit board 231 away from the overlap portion 222, the varistor 232 is spaced apart from the wear-resistant member 21, and is electrically connected to the flexible circuit board 231.

[0043] In this embodiment, the flexible circuit board 231 is disposed on the side of the overlapping portion 222 facing the wear-resistant member 21, and can fit well against the surface of the overlapping portion 222. For example, the flexible circuit board 231 can be bonded to the surface of the overlapping portion 222. When the overlapping portion 222 is compressed by the wear-resistant member 21 and undergoes bending deformation, the flexible circuit board 231 deforms along with the overlapping portion 222. The resistance value of the pressure-sensitive resistor 232 disposed on the side of the flexible circuit board 231 away from the overlapping portion 222 changes. It can be understood that the flexible circuit board 231 integrates circuit structures such as a pressure detection circuit, a signal conversion circuit, and a signal conditioning circuit that are electrically connected to the pressure-sensitive resistor 232. The pressure detection circuit can detect the voltage across the pressure-sensitive resistor 232. After the voltage signal is converted and conditioned by the signal conversion circuit, signal conditioning circuit, and other circuit structures, a pressure-sensitive signal is formed and output. In addition, the varistor 232 and the wear-resistant component 21 are spaced apart to avoid the wear-resistant component 21 pressing on the varistor 232 and causing damage to the varistor 232.

[0044] Specifically, in some embodiments, there can be multiple groups of varistor 232, such as... Figure 5 and Figure 6As shown, each group of varistor 232 includes resistors R1, R2, R3, and R4. Resistors R1 and R4 are positioned where the deformation of the flexible circuit board 231 is relatively small, while resistors R2 and R3 are positioned where the deformation of the flexible circuit board 231 is relatively large. Resistors R1, R2, R3, and R4 are connected to form a Wheatstone bridge structure (e.g., ...). Figure 7 As shown in the figure, when the overlapping part 222 bends and deforms, the deformation at the positions of resistors R1 and R4 is smaller, and the increase in resistance is relatively smaller, while the deformation at the positions of resistors R2 and R3 is larger, and the increase in resistance is larger, thus... Figure 7 When the voltage across V1 and V2 changes, the analog signal can be converted into a digital signal by a 24-bit high-precision ADC (analog to digital converter), and then conditioned by a signal conditioning circuit to form a pressure-sensitive signal output.

[0045] In one specific embodiment, such as Figure 5 and Figure 6 As shown, there are two groups of varistor 232. It can be understood that each group of four varistor 232s can be arranged in various ways. Figure 5 and Figure 6 This application only shows one possible embodiment and does not limit the specific arrangement of the pressure surface resistors 232.

[0046] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the pressure-sensitive assembly 2 further includes: a reinforcing plate 24, which is disposed on the side of the overlapping portion 222 facing the wear-resistant member 21, and a pressure-sensitive element 23 is disposed on the side of the reinforcing plate 24 away from the overlapping portion 222; wherein the wear-resistant member 21 is connected to the first end of the reinforcing plate 24 through a first protrusion 211 and to the second end of the reinforcing plate 24 through a second protrusion 212.

[0047] In this embodiment, a reinforcing plate 24 is disposed between the overlapping portion 222 and the pressure-sensitive element 23. Both ends of the reinforcing plate 24 are connected to the first protrusion 211 and the second protrusion 212 of the wear-resistant component 21, respectively. When the wear-resistant component 21 is compressed, it transmits the pressure through the first protrusion 211 and the second protrusion 212 to both ends of the reinforcing plate 24, causing the reinforcing plate 24 and the overlapping portion 222 to undergo bending deformation together. The pressure-sensitive element 23 disposed on one side of the reinforcing plate 24 can also deform synchronously and generate a corresponding pressure signal. In this embodiment, the reinforcing plate 24 and the overlapping portion 222, as a whole, jointly bear the pressure of the wear-resistant component 21, exhibiting higher strength. After being subjected to repeated compression and bending deformation by the wear-resistant component 21, they can still recover to their initial state. Even after long-term use, they can maintain the sensitivity of the pressure-sensitive component 2, effectively extending its service life. In addition, the reinforcing plate 24 and the overlapping part 222 bear the pressure as a whole and generate a small deformation due to bending deformation, which is beneficial to control the deformation of the pressure-sensitive element 23 and avoid damage to the pressure-sensitive element 23 due to excessive deformation.

[0048] In one specific embodiment, the pressure-sensitive bracket 22 is a plastic bracket, and the reinforcing plate 24 is a steel plate. A portion of the flexible circuit board 231 is attached to the side wall of the steel plate away from the overlapping portion 222. The length of the steel plate is greater than the length of the portion of the flexible circuit board 231 attached to the steel plate, so that both ends of the steel plate are exposed at both ends of the flexible circuit board 231, so that one end of the steel plate abuts against the first protrusion 211, and the other end of the steel plate abuts against the second protrusion 212.

[0049] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the first end of the overlapping part 222 is provided with a first hook 2221, and the second end of the overlapping part 222 is provided with a second hook 2222; a portion of the first protrusion 211 protrudes from the first end of the wear-resistant part 21 and is hooked in the first hook 2221, and a portion of the second protrusion 212 protrudes from the second end of the wear-resistant part 21 and is hooked in the second hook 2222.

[0050] In this embodiment, by providing a first hook 2221 and a second hook 2222 at both ends of the overlap 222, and by having a portion of the structure of the first protrusion 211 hooked in the first hook 2221 and a portion of the structure of the second protrusion 212 hooked in the second hook 2222, the connection between the overlap 222 and the wear-resistant part 21 can be strengthened. This ensures that the overlap 222 remains connected to the wear-resistant part 21 during bending deformation and recovery to its initial state, preventing the overlap 222 or the wear-resistant part 21 from undergoing plastic deformation after long-term use, which could cause them to separate and affect the sensitivity of the entire pressure-sensitive assembly 2.

[0051] Specifically, in some embodiments, the wear-resistant component 21 extends along the width direction of the pen shell 1, and the shape of the opening is adapted to the wear-resistant component 21.

[0052] It is understood that, in this application, the width direction of the pen casing 1 refers to the direction parallel to the surface of the scanning medium and perpendicular to the two sides of the dictionary pen when the dictionary pen scans the scanning medium; the length direction of the pen casing 1 refers to the direction perpendicular to the end face of the scanning end of the dictionary pen (e.g., ...). Figure 1 and Figure 8 (As shown).

[0053] In this embodiment, by setting the wear-resistant component 21 as a strip-shaped structure extending along the width direction of the pen shell 1, the strip-shaped wear-resistant component 21 can increase the contact area between the wear-resistant component 21 and the medium to be scanned, making it easier to transmit pressure. Furthermore, in the prior art, the movable foot forms a protruding corner structure at the tip of the dictionary pen, which is aesthetically unappealing. In this embodiment, the portion of the wear-resistant component 21 extending beyond the pen shell 1 is also strip-shaped and fits snugly against the scanning end surface of the pen shell 1, resulting in a more aesthetically pleasing appearance. Simultaneously, the shape of the opening matches the wear-resistant component 21; that is, the shape of the opening is consistent with the shape of the edge contour formed by the sidewall of the wear-resistant component 21. This helps to reduce the gap between the opening and the wear-resistant component 21, making the overall integrity of the scanning end of the dictionary pen better and more aesthetically pleasing.

[0054] In some embodiments, such as Figure 1 and Figure 9 As shown, the pen housing 1 has a scanning window 11, which is positioned near the scanning end. The dictionary pen also includes a scanning component 3, which is disposed in the receiving cavity and faces the scanning window 11. The scanning component 3 and the pressure-sensitive component 2 are electrically connected. The scanning component 3 is used to scan the content to be scanned as framed by the scanning window 11.

[0055] In this embodiment, a scanning window 11 is provided near the scanning end of the pen shell 1. The scanning window 11 can be used to select the content to be scanned. The scanning component 3 is configured to face the inner area of ​​the scanning window 11. The scanning component 3 includes at least a camera 31. The shooting range of the camera 31 coincides with the selection range of the scanning window 11 on the scanning medium. Thus, the scanning component 3 can be activated by the pressure signal of the pressure-sensitive component 2 and scan the content to be scanned by the scanning window 11. The scanned image data is transmitted to the control system of the dictionary pen. After processing and translation by the image processing, recognition, and translation programs built into the control system, the data is fed back to the user through an interactive device (such as a speaker, screen, etc.).

[0056] For example, the scanning window 11 can be a notch or through hole set at the scanning end, and the scanning component 3 is set on the inner wall of the notch or the hole wall of the scanning window 11. When scanning, the user can directly align the notch or through hole with the content to be scanned and press down the pen shell 1 so that the wear-resistant part 21 and the surface of the medium to be scanned come into contact and are pressed. The wear-resistant part 21 is pressed so that the pressure-sensitive component 2 sends a pressure-sensitive signal to the scanning component 3. The pressure-sensitive signal can then start the scanning component 3 and perform scanning.

[0057] Alternatively, in some embodiments, such as Figure 1 , Figure 8 and Figure 9 As shown, the dictionary pen also includes: a full-screen 4, which is located on the front of the pen shell 1. The full-screen 4 includes a first display area 41, which is used to display the content to be scanned; a groove is provided on the back of the pen shell 1, which forms a scanning window 11.

[0058] Understandably, when using a dictionary pen for scanning, the scanning end of the pen shell 1 needs to be in contact with the scanning medium. At this time, the side of the pen shell 1 adjacent to the scanning end and facing the scanning medium is the back of the pen shell 1, and the side of the pen shell 1 opposite to the back is the front of the pen shell 1. The front of the pen shell 1 is also usually the side facing the user when scanning.

[0059] In this embodiment, by setting a groove on the back of the pen shell 1 as a scanning window 11, and setting the scanning component 3 on the groove wall, the user can first roughly align the groove with the content to be scanned and press down the pen shell 1. After the wear-resistant part 21 is pressed and the scanning component 3 is triggered by the pressure-sensitive component 2 to scan, the scanning component 3 can directly project the scanned image onto the first display area 41 of the full screen 4 of the dictionary pen through the control system of the dictionary pen. The first display area 41 is used to display the content to be scanned selected by the scanning window 11 in real time. That is, the first display area 41 displays the image of the area selected by the scanning component 3 in the scanning window 11. The first display area 41 can replace the observation window on the traditional dictionary pen, making it easier for the user to more intuitively determine the area selected by the scanning window 11 on the scanning medium through the content displayed in the first display area 41, so as to scan the content to be identified.

[0060] In this embodiment, a recessed scanning window 11 is used in conjunction with a first display area 41 instead of the notch or through-hole type scanning window 11 in the previous embodiment. This eliminates the need to construct notches or holes on the front of the pen shell 1, resulting in better integrity and aesthetics of the front of the pen shell 1, and also helps to increase the display area of ​​the full-screen 4.

[0061] In some embodiments, such as Figure 8As shown, the full-screen 4 also includes a second display area 42, which is used to display associated information corresponding to the content to be scanned. In practical applications, the first display area 41 and the second display area 42 can be arranged along the length of the pen shell 1, with the display area of ​​the second display area 42 being larger than that of the first display area 41. Because the second display area 42 has a relatively large display area, the associated information displayed in the second display area 42 can include not only the scanning information obtained during the user's last scan but also the scanning information obtained during the user's current scan, so that the user can query the actual scanning information needed. For example, the second display area 42 can display associated information corresponding to the content to be scanned, including pinyin, radicals, synonyms, antonyms, information sources, and translation content. Alternatively, the second display area 42 can also display an interactive interface for user interaction, such as operation buttons that the user can touch to activate the dictionary pen's query, translation, and voice broadcast functions.

[0062] In one specific embodiment, such as Figure 9 As shown, the pen shell 1 includes a middle frame 12 and a back shell 13. The full screen 4 includes a screen body 43 and a glass cover 44. The glass cover 44 is installed on one side of the middle frame 12, and the back shell 13 is installed on the other side of the middle frame 12. The glass cover 44, the middle frame 12 and the back shell 13 together form a receiving cavity. The screen body 43 is disposed inside the glass cover 44. A groove is formed on the side of the back shell 13 away from the receiving cavity. The groove is close to the scanning end. An opening is provided on the wall surface of the scanning end away from the groove. The wear-resistant part 21 extends to the outside of the scanning end through the opening.

[0063] In some embodiments, such as Figure 3 , Figure 9 , Figure 10 and Figure 11 As shown, the scanning component 3 includes a camera 31 and a fill light 32. The camera 31 is used to capture the content to be scanned selected by the scanning window 11; the fill light 32 is used to provide supplementary lighting for the camera 31.

[0064] The camera 31 can be a small, high-resolution color camera, and the fill light 32 can be an LED light. The shooting range of the camera 31 coincides with the frame selection range of the scanning window 11 on the scanning medium. The fill light 32 is used to illuminate the frame selection range of the scanning window 11 on the scanning medium to ensure sufficient lighting for the camera 31 and thus ensure image acquisition quality. It is understood that the scanning component 3 usually also includes a control motherboard 34. The control motherboard 34 can be integrated into the entire dictionary pen control system or it can be a separate motherboard chip. The control motherboard 34 is electrically connected to the camera 31, the fill light 32, and the pressure-sensitive component 2. The control motherboard 34 is used to receive the pressure-sensitive signal from the pressure-sensitive component 2 and control the camera 31 and the fill light 32 to start scanning based on the pressure-sensitive signal.

[0065] It is understood that the camera 31 and the fill light 32 are respectively located inside the receiving cavity of the dictionary pen, and one or more light-transmitting openings are provided on the side wall of the scanning window 11. When there is only one light-transmitting opening, the camera 31 and the fill light 32 are positioned opposite to the same light-transmitting opening. When there are multiple light-transmitting openings, the camera 31 and the fill light 32 are positioned opposite to each of the multiple light-transmitting openings (e.g., two light-transmitting openings).

[0066] Optionally, lenses can be installed at each light-transmitting opening to improve the sealing of the pen casing 1.

[0067] In some embodiments, in order to ensure the supplementary lighting effect on the camera 31, multiple supplementary lights 32 are provided, and the camera 31 and multiple supplementary lights 32 are arranged side by side, with the camera 31 located between the multiple supplementary lights 32.

[0068] Optionally, two fill lights 32 can be set, with the two fill lights 32 spaced apart, and the camera 31 is set between the two fill lights 32.

[0069] Furthermore, the two supplementary lights 32 can be a white LED and an infrared LED, respectively. The white LED is used to supplement the light when the dictionary pen performs OCR (Optical Character Recognition), and the infrared LED is used to supplement the light when the dictionary pen performs OID (Optical Identification).

[0070] In one specific embodiment, such as Figure 9 , Figure 10 and Figure 11 As shown, the scanning component 3 also includes a mounting bracket 33, which includes a front bracket and a rear bracket. The camera 31 and two fill lights 32 are all mounted on the circuit board. The camera 31, the two fill lights 32 and the circuit board are fixedly connected to the pen shell 1 through the rear bracket. The front bracket is placed in front of the camera 31.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
