[0002] In related technologies, when users hold a dictionary pen or scanning pen to scan paper documents, books, and tickets, they usually move the pen body at an angle on the surface of the medium to be scanned. When the angle of the pen body is not good, it may affect the image acquisition effect of the camera on the pen body. The acquired image may have problems such as trapezoidal distortion and text line tilting, which ultimately affects the recognition function of the dictionary pen. Utility Model Content

[0003] This invention provides a dictionary pen to solve the problem in the prior art where the tilt angle between the pen body and the medium to be scanned is not ideal when the user holds the dictionary pen to scan, thus affecting the scanning effect and recognition function of the dictionary pen.

[0004] This utility model provides a dictionary pen, comprising: The pen body has a receiving cavity and an opening communicating with the receiving cavity, the opening being located at the scanning end; A pressure-sensitive element is disposed in the receiving cavity; A wear-resistant component is connected to the pressure-sensitive element and extends out of the pen body through the opening; When the angle between the pen body's length direction and the medium to be scanned is less than a preset angle, the pen body contacts the medium to be scanned, or both the pen body and the wear-resistant component are in contact with the medium to be scanned; when the angle between the pen body's length direction and the medium to be scanned is not less than a preset angle, the wear-resistant component contacts the medium to be scanned and drives the pressure-sensitive element to generate a pressure-sensitive signal.

[0005] According to the dictionary pen of this utility model, the preset angle is not less than 45°.

[0006] According to the dictionary pen of this utility model, the scanning end has a first arc-shaped surface, the opening is located on the first arc-shaped surface, and the end of the wear-resistant part exposed on the pen body has a second arc-shaped surface. The angle between the common tangent of the first arc-shaped surface and the second arc-shaped surface and the length direction of the pen body is α, and α is equal to the preset angle.

[0007] According to the dictionary pen of this utility model, the length of the wear-resistant part extending out of the pen body is not less than 0.3mm and not more than 1.2mm.

[0008] According to the dictionary pen of this utility model, the distance between the two tangent points of the common tangent lines of the first arc-shaped surface and the second arc-shaped surface is not less than 1.5 mm and not more than 4 mm.

[0009] According to the dictionary pen of this utility model, the scanning end has a first corner, and the end of the wear-resistant part extending out of the pen body has a second corner. The first corner and the second corner are used to abut against the medium to be scanned. The angle between the line connecting the first corner and the second corner and the length direction of the pen body is β, and β is equal to the preset angle.

[0010] According to the dictionary pen of this utility model, the wear-resistant component extends along the width direction of the pen body, and the shape of the opening is adapted to the wear-resistant component.

[0011] According to the dictionary pen of this utility model, the pen body is provided with a scanning window, and the scanning window is disposed close to the scanning end; The dictionary pen includes: a scanning component disposed on the pen body and facing the scanning window; the scanning component and the pressure-sensitive element are electrically connected. The scanning component is used to scan the content to be scanned as framed by the scanning window.

[0012] 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 mounted on the pen body, is used to provide illumination for the camera.

[0013] According to the dictionary pen of this utility model, there are two auxiliary lights, which are arranged at intervals along the width direction of the pen body, and the camera is located between the two auxiliary lights.

[0014] This invention relates to a dictionary pen that incorporates a wear-resistant component and a pressure-sensitive element at the scanning end of the pen body. During scanning, the wear-resistant component contacts the medium to be scanned, causing the pressure-sensitive element to deform and generate a pressure signal. This pressure signal triggers the dictionary pen's scanning function. Simultaneously, through the structural cooperation between the pen body and the wear-resistant component, the wear-resistant component only contacts the medium to trigger the scanning function when the angle between the pen body's length direction and the medium to be scanned is not less than a preset angle. This allows the user to adjust the pen body angle according to the triggering status of the scanning function, ensuring that the dictionary pen is within a favorable scanning angle range relative to the medium when the scanning function is triggered. This effectively solves the problem in existing technologies where the tilt angle between the pen body and the medium to be scanned is unfavorable when the user holds the dictionary pen to scan, thus affecting the scanning effect and recognition function.

[0020] 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.

[0021] The following is combined Figures 1-3 This invention describes a dictionary pen.

[0022] like Figure 1 and Figure 2As shown, this utility model provides a dictionary pen 1, including: a pen body 11, a pressure-sensitive element (not shown in the figure), and a wear-resistant part 12. The pen body 11 has a receiving cavity and an opening communicating with the receiving cavity, the opening being located at the scanning end 111; the pressure-sensitive element is disposed in the receiving cavity; the wear-resistant part 12 is connected to the pressure-sensitive element and extends out of the pen body 11 through the opening; when the angle between the length direction of the pen body 11 and the medium to be scanned is less than a preset angle, the pen body 11 is in contact with the medium to be scanned, or both the pen body 11 and the wear-resistant part 12 are in contact with the medium to be scanned; when the angle between the length direction of the pen body 11 and the medium to be scanned is not less than the preset angle, the wear-resistant part 12 is in contact with the medium to be scanned and drives the pressure-sensitive element to generate a pressure signal.

[0023] It is understood that the pen body 11 in this embodiment is used to install other functional components of the dictionary pen 1, and the scanning end 111 of the pen body 11 is the end of the dictionary pen 1 used to align with the medium to be scanned when scanning. The scanning medium can be a planar medium capable of displaying text and images, such as paper or a screen.

[0024] The pen body 11 has a receiving cavity for housing a pressure-sensitive element and a wear-resistant component 12. Part of the wear-resistant component 12 is located within the receiving cavity, while a portion extends beyond the pen body 11 to contact the surface of the medium being scanned during scanning. The wear-resistant component 12 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 12 and the medium being scanned, and between the wear-resistant component 12 and the inner wall of the pen body 11, thereby extending its service life.

[0025] The wear-resistant part 12, located within the receiving cavity, is connected to the pressure-sensitive element. During scanning, the wear-resistant part 12 contacts the surface of the medium to be scanned. Under pressure from the medium, it transmits the pressure to the pressure-sensitive element, causing deformation at the contact point between the pressure-sensitive element and the wear-resistant part 12, thus generating a pressure-sensitive signal from the pressure-sensitive element. It can be understood that the pressure-sensitive signal from the pressure-sensitive element can be transmitted to the control system (such as the motherboard) of the dictionary pen 1. Upon receiving the corresponding pressure-sensitive signal, the control system controls the dictionary pen 1 to initiate the scanning function.

[0026] Meanwhile, in this embodiment, the wear-resistant foot 11 is configured to contact the medium to be scanned and drive the pressure-sensitive element to generate a pressure-sensitive signal when the pen body 11 is in a specific posture with the medium to be scanned, thereby triggering the scanning function of the dictionary pen 1. Specifically, by matching the dimensions and structure of the pen body 11 and the wear-resistant component 12, when the angle between the length direction of the pen body 11 and the medium to be scanned is too small (i.e., less than a preset angle), a portion of the structure of the pen body 11 contacts the medium to be scanned, thereby restricting the position of the wear-resistant component 12. This prevents the wear-resistant component 12 from contacting the medium to generate a pressure-sensitive signal, or allows the wear-resistant component 12 to only make slight contact with the medium, but not enough to cause the pressure-sensitive element to generate a pressure-sensitive signal. Only when the angle between the length direction of the pen body 11 and the medium to be scanned reaches the preset angle can the wear-resistant component 12 contact the medium to be scanned and form sufficient pressure between them to deform the pressure-sensitive element and generate a pressure-sensitive signal. In addition, when the angle between the length direction of the pen body 11 and the medium to be scanned is not less than the preset angle, and the wear-resistant component 12 contacts the medium to be scanned and drives the pressure-sensitive element to generate a pressure-sensitive signal, the pen body can also contact the medium to be scanned, as long as this contact does not interfere with the wear-resistant component 12 triggering the pressure-sensitive element.

[0027] Understandably, the preset angle can be set according to the optimal scanning angle of the scanning component 13 on the pen body 11, so as to ensure that the scanning component 13 can have a better scanning angle when the user adjusts the pen body 11 to the point where the angle between the length direction of the pen body 11 and the medium to be scanned reaches or exceeds the preset angle.

[0028] This design ensures that the scanning function of the dictionary pen 1 is only triggered when the user adjusts the pen body 11 to a specific angle. The user can determine whether the current posture of the pen body 11 is appropriate based on whether the scanning function of the dictionary pen 1 is triggered, and adjust the tilt angle of the pen body 11 relative to the medium to be scanned until the pen body 11 reaches an angle suitable for the scanning component 13 to perform scanning. The pressure-sensitive element generates a pressure-sensitive signal to trigger the scanning function of the scanning component 13, so as to ensure the image acquisition effect of the scanning component 13 and the subsequent recognition function.

[0029] Furthermore, the grip feel of the pen body 11 is different when the wear-resistant part 12 is in contact with the medium to be scanned or not. The user can also judge whether the current tilt of the pen body 11 is appropriate based on the grip feel of the pen body 11 and the triggering status of the dictionary pen 1 scanning function. If the wear-resistant part 12 is not in contact with the medium to be scanned and the dictionary pen 1 scanning function is not triggered, the user can adjust the tilt of the pen body 11 in real time until the wear-resistant part 12 comes into contact with the medium to be scanned and the dictionary pen 1 scanning function is activated.

[0030] The dictionary pen 1 of this invention features a wear-resistant component 12 and a pressure-sensitive element at the scanning end 111 of the pen body 11. During scanning, the wear-resistant component 12 contacts the medium to be scanned, causing the pressure-sensitive element to deform and generate a pressure signal. This pressure signal triggers the scanning function of the dictionary pen 1. Simultaneously, through the structural cooperation between the pen body 11 and the wear-resistant component 12, the wear-resistant component 12 will only exert sufficient pressure on the medium to trigger the scanning function of the dictionary pen 1 when the angle between the pen body 11 and the medium to be scanned is not less than a preset angle. This allows the user to adjust the angle of the pen body 11 according to the triggering status of the scanning function, ensuring that the dictionary pen 1 is within a good scanning angle range relative to the medium when the scanning function is triggered. This ensures the scanning and recognition effect of the dictionary pen 1 and effectively solves the problem in the prior art where the tilt angle between the pen body and the medium to be scanned is poor when the user holds the dictionary pen for scanning, thus affecting the scanning effect and recognition function.

[0031] Specifically, in some embodiments, the preset angle is not less than 45°.

[0032] Understandably, the normal of the scanning lens of the dictionary pen 1 is usually at a downward angle to the length direction of the pen body 11. This embodiment limits the preset angle to no less than 45°, ensuring that the scanning function of the dictionary pen 1 is triggered only when the angle between the length direction of the pen body 11 and the medium to be scanned reaches 45° or more. This ensures that when the pen body 11 moves on the medium to be scanned, the plane containing the angle between the normal of the scanning lens and the medium to be scanned is as close to a right angle as possible, allowing the scanning lens to capture images nearly perpendicularly and improving image acquisition quality.

[0033] In some embodiments, such as Figure 2 As shown, the scanning end 111 has a first arc-shaped surface 1111, and the opening is located on the first arc-shaped surface 1111. The end of the wear-resistant part 12 extending out of the pen body 11 has a second arc-shaped surface 121. The angle between the common tangent of the first arc-shaped surface 1111 and the second arc-shaped surface 121 and the length direction of the pen body 11 is α, and α is equal to the preset angle.

[0034] In this embodiment, the end face of the scanning end 111 is a first arc-shaped surface 1111, and the end face of the end of the wear-resistant part 12 extending out of the pen body 11 is a second arc-shaped surface 121. The first arc-shaped surface 1111 and the second arc-shaped surface 121 can reduce collisions and wear with the medium being scanned when they come into contact. Simultaneously, by making the common tangent of the first arc-shaped surface 1111 and the second arc-shaped surface 121 (i.e., ...) Figure 2 The solid line m in the middle) and the length direction of the pen body 11 (i.e. Figure 2The included angle α between the dotted lines n) is equal to the preset angle. When the included angle between the length direction of the pen body 11 and the medium to be scanned is less than the included angle α, the first arc surface 1111 will contact the medium to be scanned first, so that the second arc surface 121 cannot contact the medium to be scanned without rotating the pen body 11. When the included angle between the length direction of the pen body 11 and the medium to be scanned is not less than the included angle α, the second arc surface 121 can contact the medium to be scanned so as to drive the wear-resistant part 12 to press the pressure-sensitive element and generate a pressure-sensitive signal.

[0035] It is understood that the common tangent of the first arcuate surface 1111 and the second arcuate surface 121 in this embodiment refers to the common tangent of the arcuate contour formed by projection in the vertical plane, and the common tangent is one that is close to the lower edge of the first arcuate surface 1111.

[0036] In some embodiments, the length of the portion of the wear-resistant component 12 extending beyond the pen body 11 is not less than 0.3 mm and not more than 1.2 mm. In this embodiment, by limiting the upper and lower limits of the length of the wear-resistant component 12, it is possible to avoid the wear-resistant component 12 extending too far or too short beyond the pen body 11. An excessively long wear-resistant component 12 is easily damaged and will also affect the integrity and aesthetics of the scanning end 111 of the pen body 11. An excessively short wear-resistant component 12 will have difficulty contacting the medium to be scanned and generating sufficient pressure between the wear-resistant component 12 and the medium to drive the pressure-sensitive element to generate a pressure-sensitive signal.

[0037] In some embodiments, the length of the portion of the wear-resistant part 12 extending out of the pen body 11 can be 0.8 mm or 1 mm.

[0038] In some embodiments, the distance between the two tangent points of the common tangent line of the first arcuate surface 1111 and the second arcuate surface 121 is not less than 1.5 mm and not more than 4 mm. In this embodiment, by limiting the distance between the tangent points of the two arcuate surfaces and the common tangent line, the position of the wear-resistant component 12 on the first arcuate surface 1111 is defined, so that when the angle between the wear-resistant component 12 and the surface of the medium to be scanned in the length direction of the pen body 11 reaches a preset angle or higher, the wear-resistant component 12 can contact the medium to be scanned and drive the pressure-sensitive element to generate a pressure-sensitive signal.

[0039] In some embodiments, the distance between the two tangent points of the common tangent line of the first arcuate surface 1111 and the second arcuate surface 121 is 2 mm.

[0040] In some other embodiments not shown, the scanning end 111 has a first corner, and the end of the wear-resistant part 12 extending out of the pen body 11 has a second corner. The first corner and the second corner are used to contact the medium to be scanned. The angle between the line connecting the first corner and the second corner and the length direction of the pen body 11 is β, and β is equal to a preset angle.

[0041] In this embodiment, a first corner is formed on the scanning end 111 for contacting the medium to be scanned, and a second corner is formed on the end of the wear-resistant member 12 extending out of the pen body 11 for contacting the medium to be scanned. By making the angle β between the line connecting the first corner and the second corner and the length direction of the pen body 11 equal to a preset angle, when the angle between the length direction of the pen body 11 and the medium to be scanned is less than the angle β, the first corner will contact the medium to be scanned first, so that the second corner cannot contact the medium to be scanned without rotating the pen body 11; when the angle between the length direction of the pen body 11 and the medium to be scanned is not less than the angle α, the second corner can contact the medium to drive the wear-resistant member 12 to press the pressure-sensitive element and generate a pressure-sensitive signal.

[0042] It is understood that both the first corner and the second corner are formed by bending and connecting two sides. In this embodiment, the line connecting the first corner and the second corner refers to a straight line that is perpendicular to the side of the first corner and the folded edge of the second corner, respectively.

[0043] In some embodiments, such as Figure 3 As shown, the wear-resistant part 12 extends along the width direction of the pen body 11, and the shape of the opening is adapted to the wear-resistant part 12.

[0044] It is understood that, in this application, the width direction of the pen body 11 refers to the direction that is parallel to the surface of the scanning medium and perpendicular to the two sides of the dictionary pen 1 when the dictionary pen 1 scans the scanning medium.

[0045] In this embodiment, by setting the wear-resistant component 12 as a strip-shaped structure extending along the width direction of the pen body 11, the strip-shaped wear-resistant component 12 can increase the contact area between the wear-resistant component 12 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 pen tip, which is aesthetically unappealing. In this embodiment, the portion of the wear-resistant component 12 extending beyond the pen body 11 is also strip-shaped and fits snugly against the surface of the scanning end 111 of the pen body 11, resulting in a more aesthetically pleasing appearance. Simultaneously, the shape of the opening matches the wear-resistant component 12; 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 12. This helps to reduce the gap between the opening and the wear-resistant component 12, making the overall integrity of the scanning end 111 of the dictionary pen 1 better and more aesthetically pleasing. At the same time, the strip-shaped wear-resistant component 12 can better transmit pressure to the user, allowing the user to judge whether the wear-resistant component 12 is in contact with the medium to be scanned through the feel of the grip and adjust the posture of the pen body 11 accordingly.

[0046] In some embodiments, such as Figure 3As shown, the pen body 11 is provided with a scanning window 112, which is located near the scanning end 111; the dictionary pen 1 also includes a scanning component 13, which is located on the pen body 11 and faces the scanning window 112, and is electrically connected to the pressure-sensitive element; wherein, the scanning component 13 is used to scan the content to be scanned selected by the scanning window 112.

[0047] In this embodiment, a scanning window 112 is provided on the pen body 11 near the scanning end 111. The scanning window 112 can be used to select the content to be scanned. The scanning component 13 is configured to face the inner area of ​​the scanning window 112. The scanning component 13 includes at least a camera 131. The shooting range of the camera 131 coincides with the selection range of the scanning window 112 on the scanning medium. Thus, the scanning component 13 can be activated under the trigger of the pressure-sensitive signal of the pressure-sensitive element and scan the content to be scanned by the scanning window 112. The scanned image data is transmitted to the control system of the dictionary pen 1. After processing and translation by the image processing, recognition, translation and other programs built into the control system, the data is fed back to the user through an interactive device (such as a speaker, screen, etc.).

[0048] For example, the scanning window 112 can be a notch or through hole provided on the scanning end 111, and the scanning component 13 is provided on the inner wall of the notch or the hole wall of the scanning window 112. When scanning, the user can directly align the notch or through hole with the content to be scanned, and adjust the pen body 11 to a suitable angle and press it down so that the wear-resistant part 12 and the surface of the medium to be scanned come into contact and are pressed. The wear-resistant part 12 is pressed so that the pressure-sensitive element sends a pressure-sensitive signal to the scanning component 13. The pressure-sensitive signal can then start the scanning component 13 and perform scanning.

[0049] In some embodiments, such as Figure 3 As shown, the scanning component 13 includes a camera 131 and a fill light 132. The camera 131 is used to capture the content to be scanned selected by the scanning window 112; the fill light 132 is set on the pen body 11 and is used to provide illumination for the camera 131.

[0050] In this embodiment, the camera 131 can be a small, high-resolution color camera. The shooting range of the camera 131 coincides with the frame selection range of the scanning window 112 on the scanning medium. In this embodiment, the supplementary light 132 can be an LED light to illuminate the frame selection range of the scanning window 112 on the scanning medium, so as to ensure sufficient shooting light for the camera 131 and thus ensure image acquisition quality. It is understood that the scanning component 13 usually also includes a control motherboard. The control motherboard can be integrated into the entire control system of the dictionary pen 1, or it can be a separate motherboard chip. The control motherboard is electrically connected to the camera 131, the supplementary light 132, and the pressure-sensitive element. The control motherboard is used to receive the pressure-sensitive signal from the pressure-sensitive element and control the camera 131 and the supplementary light 132 to start scanning according to the pressure-sensitive signal.

[0051] In some embodiments, in order to ensure the supplementary lighting effect on the camera 131, multiple supplementary lights 132 are provided, and the camera 131 and multiple supplementary lights 132 are arranged side by side, with the camera 131 located between the multiple supplementary lights 132.

[0052] In some embodiments, such as Figure 3 As shown, there are two fill lights 132, which are arranged at intervals along the width of the pen body 11, and the camera 131 is located between the two fill lights 132.

[0053] Furthermore, the two supplementary lights 132 can be a white LED and an infrared LED, respectively. The white LED is used to supplement the light when the dictionary pen 1 performs OCR (Optical Character Recognition), and the infrared LED is used to supplement the light when the dictionary pen 1 performs OID (Optical Identification).

[0054] In some embodiments, the pen body 11 is provided with a light-transmitting hole, the camera 131 is disposed inside the light-transmitting hole, the lens of the camera 131 is coaxially disposed with the light-transmitting hole, and a protective lens is provided at the outer end of the light-transmitting hole.

[0055] It is understood that in this embodiment, the light-transmitting hole is located on the side wall of the scanning window 112, and the camera 131 captures an image of the content to be scanned through the light-transmitting hole. The camera 131 is fixed inside the pen body 11. To prevent external dust from entering the camera 131, a protective lens is provided at the outer end of the light-transmitting hole. The protective lens is made of a light-transmitting material. The outer end of the light-transmitting hole refers to the end located outside the pen body 11 along the direction of the hole axis.

[0056] 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.
