[0028] 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 protection scope of this utility model.

[0029] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "first" and "second" are numbered for the purpose of clearly identifying product components and do not represent any substantial difference. The terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this invention according to the specific circumstances.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the dictionary pen provided in this embodiment of the present invention includes a housing 1 and a cover plate 2. The housing 1 is provided with an observation window 11. The cover plate 2 is disposed on the housing 1 and covers the observation window 11. The cover plate 2 has a first cover plate portion 21 opposite to the observation window 11, and the first cover plate portion 21 can switch between a light-transmitting state and a light-blocking state under the action of an electrical signal.

[0031] It should be noted that the cover plate 2 may only have the first cover plate portion 21, see [reference]. Figure 4The cover plate 2 in the figure is the first cover plate portion 21, the area of ​​which can be the same as or larger than the area of ​​the observation window 11. Alternatively, the first cover plate portion 21 may be only a part of the cover plate 2, see [reference needed]. Figure 1 and Figure 2 .

[0032] The housing 1 has a first side and a second side facing away from each other. The first side corresponds to the front of the dictionary pen, and the second side corresponds to the back of the dictionary pen. The first side of the housing 1 has an observation window 11, and the second side has a scanning window 12, which are arranged opposite to each other. The scanning window 12 is located at the end of the second side and is used to select the object to be scanned. The observation window 11 is located at the end of the first side, allowing the user to observe the object to be scanned.

[0033] The first cover plate portion 21 being in a light-transmitting state means that the visible light transmittance of the first cover plate portion 21 is greater than a first preset value, such as a visible light transmittance greater than 90%, and the first cover plate portion 21 in the light-transmitting state can be colorless or colored. The first cover plate portion 21 being in a light-blocking state means that the visible light transmittance of the first cover plate portion 21 is less than a second preset value, such as a visible light transmittance less than 90%.

[0034] When the scanning function of the dictionary pen is needed, the first cover plate 21 is switched to a light-transmitting state so that the object to be scanned can be observed through the viewing window 11. When the scanning function of the dictionary pen is not needed, the first cover plate 21 is switched to a light-blocking state to block the viewing window 11. The viewing window 11 of the dictionary pen is no longer a notch, thereby improving the consistency of the front structure of the dictionary pen.

[0035] Specifically, the first cover plate 21 is equipped with a driving circuit, which is electrically connected to the control motherboard inside the dictionary pen. This allows the first cover plate 21 to switch between a light-transmitting state and a light-blocking state under the drive of a signal from the control motherboard; or, the first cover plate 21 can switch to a light-transmitting state under the drive of a first signal from the control motherboard, and switch to a light-blocking state under the drive of a second signal from the control motherboard. The specific driving method is related to the relevant technology used in the first cover plate 21.

[0036] The dictionary pen provided in this embodiment of the invention has a first cover portion 21 on the cover plate 2 corresponding to the observation window 11, which can switch between a light-transmitting state and a light-blocking state under the action of an electrical signal. When the scanning function is needed, the first cover portion 21 is switched to the light-transmitting state so that the user can observe the content to be scanned; when the scanning function is not needed, the first cover portion 21 can be switched to the light-blocking state to block the observation window 11, thereby improving the consistency of the front structure of the dictionary pen and also improving the appearance of the dictionary pen.

[0037] In some embodiments of this invention, the first cover plate portion 21 is electrochromic glass. Specifically, a first conductive layer, an electrochromic layer, an electrolyte layer, an ion storage layer, and a second conductive layer are sequentially stacked within the first cover plate portion 21. The first conductive layer and the second conductive layer are connected to the driving circuit.

[0038] Optionally, when a voltage is applied between the first conductive layer and the second conductive layer, the generated electric field drives ions to migrate from the ion storage layer to the electrochromic layer, where they react with the material, causing a change in its chemical state. This results in the first cover portion 21 appearing colorless or light-colored, i.e., a light-transmitting state. When a reverse voltage is applied between the first and second conductive layers, or when no voltage is applied, the ions migrate back to the ion storage layer, and the electrochromic layer returns to its initial color state, i.e., a light-blocking state.

[0039] It should be noted that the voltage driving ions to migrate from the ion storage layer to the electrochromic layer can be either a positive or a negative voltage, depending on the type of electrochromic material, the migration characteristics of the ions, and the properties of the electrolyte layer.

[0040] In some embodiments of this invention, the first cover plate portion 21 is a liquid crystal glass. Specifically, a liquid crystal layer is provided inside the first cover plate portion 21. When an external electric field is applied to the liquid crystal layer, the electric field causes the liquid crystal molecules to rearrange into an ordered state, allowing light to pass through the liquid crystal layer, i.e., it is in a light-transmitting state. When the external electric field is removed, the liquid crystal molecules return to their original disordered arrangement state, making it difficult for light to pass through, i.e., it is in a light-blocking state.

[0041] The switching between the light-transmitting and light-blocking states of the first cover plate portion 21 in this embodiment of the present invention is not limited to the electrochromic technology and liquid crystal technology mentioned above, but can also be achieved through polymer-dispersed liquid crystal technology and suspended particle device technology, etc.

[0042] like Figure 4 As shown, the dictionary pen provided in this embodiment of the present invention also includes a display screen 3. The display screen 3 and the cover plate 2 are located on the same side of the housing 1. The color of the first cover plate portion 21 in the light-shielding state is the same as the color of the display screen 3 in the screen-off state.

[0043] The display screen 3 is black or a dark color when the screen is off, and correspondingly, the first cover plate 21 is also black or a dark color when the screen is shielded from light. It should be noted that the color of the first cover plate 21 in the shielded state and the color of the display screen 3 in the off state are the same, based on the color difference that is not easily distinguishable to the naked eye, and a certain difference in transmittance between the two is allowed.

[0044] Specifically, the housing 1 also has a display window, with an observation window 11 spaced apart from the display window. A display screen 3 is positioned on the display window. The display window and observation window 11 are arranged along the length of the housing 1, with the observation window 11 positioned near one end of the housing 1, and the display window extending from one side of the observation window 11 to the other end of the housing 1. This allows the display screen 3 and the first cover plate 21 to cover most of the front area of ​​the housing 1, ensuring good consistency in the front structure of the dictionary pen when the display screen 3 is off and the first cover plate 21 is in a light-blocking state.

[0045] In some of the alternative embodiments, such as Figure 4 As shown, the cover 2 only covers the viewing window 11, meaning that the display screen 3 and the cover 2 are spaced apart on the front of the dictionary pen. In this case, the display screen 3 can be equipped with a separate protective cover, which is fixed to the display side of the display screen 3 to form a display module.

[0046] In some alternative embodiments, see Figure 2 The cover plate 2 covers the display screen 3 and the viewing window 11. The cover plate 2 also has a transparent second cover plate portion 22, which is opposite to the display screen 3.

[0047] The first cover portion 21 of the cover plate 2 covers the observation window 11. The observation window 11 in the light-transmitting state is used to observe the text, and the observation window 11 in the light-blocking state is used to block the observation window 11. The second cover portion 22 covers the display screen 3 to protect the display screen 3.

[0048] Optionally, the display window and the viewing window 11 can be two separate openings on the housing 1, with the cover plate 2 simultaneously covering both openings. Alternatively, the display window and the viewing window 11 can be integrally formed into one large opening, with the cover plate 2 embedded within this opening and pressed between the display screen 3 and the housing 1. In this way, the display screen 3 and the viewing window 11 share a single cover plate 2, further enhancing the consistency of the dictionary pen's front structure and increasing the simplicity of the dictionary pen's appearance.

[0049] Furthermore, the display screen 3 is fixed to the second cover plate 22. Optionally, the display screen 3 is bonded to the second cover plate 22 with optical adhesive. In this way, the display screen 3 and the cover plate 2 are fixed to form a display module. During installation, the display module is directly installed on the housing 1, and the cover plate 2 of the display module covers the observation window 11, simplifying the installation process.

[0050] In some embodiments of this utility model, a printing layer is provided on the area of ​​the cover plate 2 outside the first cover plate portion 21, and the color of the first cover plate portion 21 in the light-shielding state is the same as the color of the printing layer.

[0051] Specifically, the cover plate 2 has a viewing area and a printing area. The first cover plate part 21 is located in the viewing area, that is, the observation window 11 is positioned opposite to the viewing area. The area outside the viewing area is the printing area, which can shield and decorate the edges of the observation window 11, improving the appearance.

[0052] When the display screen 3 is provided, the cover plate 2 has two viewing areas, one corresponding to the first cover plate portion 21 and the other corresponding to the second cover plate portion 22. The printing area can be screen-printed with ink to form a printing layer. The area outside the two viewing areas is the printing area. The printing area can shield and decorate the edges of the viewing window 11 and the display screen 3 or the display window, improving the appearance.

[0053] For example, if the printed layer is black, then the first cover plate 21 can be set to black in the light-shielding state. When the display screen 3 is present, when the display screen 3 is off and the first cover plate 21 is powered off, the entire cover plate 2 is black, giving the dictionary pen a consistent and minimalist appearance. The printed layer can also be blue or other colors, depending on the electrochromic material and manufacturing process used in the first cover plate 21.

[0054] In some embodiments of this utility model, the color of the first cover plate portion 21 in the light-shielding state is the same as the color of the housing 1.

[0055] For example, if the housing 1 is black, then the color of the first cover portion 21 in the light-shielding state can also be set to black. When a display screen 3 is present, when the display screen 3 is off and the first cover portion 21 is powered off, the display screen 3, the first cover portion 21, and the housing 1 are all black, giving the dictionary pen a consistent and minimalist appearance. The housing 1 can also be blue or other colors, depending on the electrochromic material and manufacturing process used in the first cover portion 21.

[0056] The dictionary pen provided in this embodiment of the invention also includes a power interface, and the first cover plate 21 is electrically connected to the power interface. When the circuit between the power interface and the first cover plate 21 is connected, the first cover plate 21 switches to a light-transmitting state. When the circuit between the power interface and the first cover plate 21 is disconnected, the first cover plate 21 switches to a light-blocking state. The dictionary pen also includes a motherboard, with the power interface disposed on the motherboard, and the drive circuit within the first cover plate 21 is electrically connected to the power interface.

[0057] In some alternative embodiments, the power interface can be a CPU power interface. When the dictionary pen is powered on, the power interface simultaneously connects the CPU and the first cover plate 21, causing the first cover plate 21 to switch from a light-blocking state to a light-transmitting state; when the dictionary pen is powered off, the first cover plate 21 loses power supply and switches from a light-transmitting state to a light-blocking state.

[0058] In some alternative embodiments, the power interface is the power interface for the scanning component. Specifically, the dictionary pen provided in this embodiment of the present invention further includes a scanning switch and a scanning component. The scanning component and the first cover plate 21 are electrically connected to the power interface via the scanning switch. When the scanning switch is closed, the scanning component is activated and the first cover plate 21 switches to a light-transmitting state. When the scanning switch is open, the scanning component is deactivated and the first cover plate 21 switches to a light-blocking state.

[0059] Understandably, the first cover plate 21 and the scanning assembly share a single scanning switch. When scanning is required, the scanning switch is triggered, simultaneously energizing both the scanning assembly and the first cover plate 21, causing the first cover plate 21 to switch from a light-blocking state to a light-transmitting state. When the scanning switch is turned off, the scanning function is disabled, and the first cover plate 21 loses its power supply, switching back from a light-transmitting state to a light-blocking state.

[0060] The scan switch can refer to a switch embedded in the housing 1 for the user to press or touch. Alternatively, it can refer to a switching device on the motherboard's control circuitry, which can be controlled by virtual buttons on the display screen.

[0061] In this embodiment of the utility model, the housing 1 includes a first housing 101 and a second housing 102 that are interlocked. See [reference needed] Figure 1 and Figure 4 The first housing 101 has a first through hole forming an observation window 11, and the second housing 102 has a second through hole forming a scanning window 12. See [reference needed]. Figure 3 The scanning window 12 and the observation window 11 are set relative to each other.

[0062] It is understood that the first housing 101 is the front housing of the dictionary pen, corresponding to the front side of the dictionary pen. The second housing 102 is the rear housing of the dictionary pen, corresponding to the back side of the dictionary pen. The two are fastened together to form housing 1. The observation window 11 is located on the inner side of the outer periphery of the first housing 101, and the scanning window 12 is located on the inner side of the outer periphery of the second housing 102.

[0063] Compared to the prior art where a notch is provided at the end of the housing 1 to form an observation window and a scanning window, this embodiment allows the housing 1 to have a complete outer periphery, avoiding the observation window 11 and the scanning window 12 from disrupting the consistency of the outer periphery structure of the housing 1.

[0064] 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.
