[0034] like Figure 1 As shown, the utility model provides a learning device, comprising:

[0035] The scanning body 1 includes a holding portion 11 and a scanning unit arranged at one end of the holding portion 11, and the scanning unit is used to scan the surface of the scanning medium.

[0036] The camera module 2 is installed at the other end of the holding portion 11 and extends to the outside of the holding portion 11 , and the lens of the camera module 2 faces the front of the scanning body 1 .

[0037] The device body 3 is mounted on the holding portion 11 and is in communication connection with the scanning unit, wherein the device body 3 has a display screen.

[0038] The learning device can be a word treasure, listening and speaking treasure, a learning machine or a repeater, etc. Taking the learning device as an example, the device body 3 can realize various functions of a traditional learning machine, and the scanning body 1 is integrated on the device body 3, so that the learning machine has a scanning function, thereby improving the integration of the device.

[0039] Specifically, if Figure 1 As shown, the bottom of the grip portion 11 is the scanning end of the grip portion 11. A scanning window 12 is provided at the bottom of the grip portion 11, which is used to frame the content to be scanned during scanning. The scanning unit can be integrated with the grip portion 11 or detachably connected to the grip portion 11. The scanning unit is located within the scanning window 12 and is used to capture the text on the medium when sliding over the medium, providing scan data input to the scanning body 1 after OCR recognition.

[0040] like Figure 1 As shown, the grip portion 11 is long and narrow, designed to be held by a human hand. During scanning, the user grasps the grip portion 11 and moves it along the surface of the scanning medium, allowing the scanning unit to scan the content. An on / off switch 15 is provided on the side of the grip portion 11. The user activates the on / off switch 15 to turn the learning device on and off.

[0041] The device body 3 is fixedly or rotatably mounted on the front of the grip 11, for example, on the end of the grip 11 away from the scanning unit. Optionally, a portion of the device body 3 is exposed, exposing the scanning unit 1, to expand the display screen size of the device body 3, enhance the user experience, and reduce eye damage. For example, the width of the device body 3 may be greater than the width of the grip 11. And / or, the top of the device body 3 may be higher than the top of the grip 11.

[0042] Specifically, a first processor is installed within the scanning body 1. The first processor is installed within the holding portion 11. The scanning unit is electrically connected to the first processor, and the first processor is electrically connected to the device body 3, thereby achieving a communication connection between the scanning unit and the device body 3. The scanning unit sends the scan information to the first processor. The first processor can translate the scan information and transmit the translation result to the device body 3 for display. Alternatively, the first processor transmits the scan information and the translation information together to the device body 3 for display, so that the user can compare and view them.

[0043] In some embodiments, the display screen of the device body 3 is a touch screen. The user can control the opening or closing of the device body 3 through the touch screen.

[0044] like Figure 4 As shown, the camera module 2 is mounted on the top of the grip portion 11. Optionally, the camera module 2 is exposed on the top surface of the grip portion 11 to ensure that the device body 3 does not block the shooting field of view of the camera module 2.

[0045] The camera module 2 serves as the front camera of the learning device, and its field of view faces the front of the scanning body 1. When the medium to be scanned is a long text, the user can quickly record or shoot the text through the camera module 2 to improve the efficiency of word retrieval. Specifically, the camera module 2 is connected to the first processor in communication to send the recording or shooting information to the first processor. The first processor can translate the text and transmit the translation result to the device body 3 for display by the user. In addition, the camera module 2 can also be used as a camera for daily photo and video recording.

[0046] The present invention provides a learning device, wherein a scanning body 1 includes a holding portion 11 and a scanning unit arranged at one end of the holding portion 11. As the human hand moves, the scanning unit can scan the surface of the scanning medium; the camera module 2 is installed at the other end of the holding portion 11 and extends to the outside of the holding portion 11 to ensure that the camera module 2 has a larger shooting field of view. The user can quickly enter a single question to be analyzed or a text to be translated through the camera module 2, thereby improving the use efficiency of the learning device; the device body 3 is installed on the holding portion 11 and communicates with the scanning unit to realize information sharing and can display the scanning results with the help of a display screen for the user to view, thereby integrating the scanning unit and the camera module 2 on the learning device, enriching the functions of the learning device and improving the user's convenience.

[0047] Specifically, in some embodiments, Figure 1 、 Figure 3 and Figure 4 As shown, the learning device further includes a mounting base 4. One end of the mounting base 4 is located inside the grip portion 11 and fixedly connected to the grip portion 11, and the other end of the mounting base 4 extends outside the grip portion 11 and is provided with a mounting groove 41. The camera module 2 is fixed to the mounting groove 41.

[0048] The mounting base 4 is used to provide support for the camera module 2. Figure 1 、 Figure 3 and Figure 4 As shown, the mounting base 4 is fixed to the center of the top of the grip portion 11 and extends outward from the grip portion 11. The mounting base 4 can also be fixed to the top edge of the grip portion 11. The mounting base 4 and the outer shell of the grip portion 11 can be detachably connected using fasteners such as screws, or the mounting base 4 and the outer shell of the grip portion 11 can be integrally connected.

[0049] The mounting groove 41 is provided on the portion of the mounting base 4 that exposes the grip portion 11. The camera module 2 is located in the mounting groove 41, with the notch of the mounting groove 41 facing the front of the scanning body 1, thereby ensuring that the camera module 2 has a field of view facing the front of the learning device.

[0050] In some embodiments, the device body 3 can be rotatably mounted on the front side of the scanning body 1 .

[0051] When the device body 3 is rotated to the first position relative to the scanning body 1, the length direction of the device body 3 is consistent with the length direction of the scanning body 1. Figure 1 and Figure 2 As shown, the device body 3 rotates to a first position relative to the scanning body 1 , and the length direction of the device body 3 is parallel to the length direction of the scanning body 1 .

[0052] like Figure 3 and Figure 4 As shown, when the device body 3 is rotated to the second position relative to the scanning body 1 , the length direction of the device body 3 is perpendicular to the length direction of the scanning body 1 .

[0053] By rotatably mounting the device body 3 on the scanning body 1 , the device body 3 can be switched between vertical and horizontal orientations to adapt to different usage habits of users, thereby improving the user experience and increasing convenience.

[0054] The device body 3 is mounted on the scanning body 1 in a manner that allows for manual or automatic rotation. For example, the device body 3 is rotatably mounted on the scanning body 1 via a driver. An operation key 13 is provided on the scanning body 1. The operation key 13 is electrically connected to the driver. When triggered, the operation key 13 is configured to control the rotation of the device body 3 to a predetermined angle.

[0055] The driving member is fixed inside the holding portion 11. The driving end of the driving member is connected to the back of the device body 3 to drive the device body 3 to rotate relative to the scanning body 1. Optionally, the driving member can be a stepping motor or a servo motor.

[0056] Further, if Figure 2 As shown, the operation key 13 is provided on the grip portion 11. The operation key 13 is electrically connected to the drive member. The user triggers the operation key 13 to turn the drive member on or off. Optionally, the operation key 13 can be a knob or a button.

[0057] Optionally, the driving member drives the device body 3 to rotate a preset angle once. When in use, after the user triggers the operation key 13, the driving member automatically turns off each time it drives the device body 3 to rotate a preset angle. In some application scenarios, the preset angle is 90°. For example, the initial position of the device body 3 relative to the scanning body 1 is the first position. The user triggers the operation key 13, and the device body 3 rotates 90° clockwise or counterclockwise relative to the scanning body 1 to the second position. At this time, Figure 1 and Figure 2 As shown, the length direction of the device body 3 is perpendicular to the length direction of the scanning body 1. The user triggers the operation key 13 again, and the device body 3 rotates 90° in the opposite direction relative to the scanning body 1, so that the length direction of the device body 3 is parallel to the length direction of the scanning body 1. Therefore, the user can control the drive member by triggering the operation key 13, thereby realizing the switching of the device body 3 between the first position and the second position. Depending on the user's usage habits, the preset angle of each rotation of the device body 3 can also be set to other angles. For example, 45° or 60°, etc. This utility model does not make any specific restrictions on this.

[0058] In other embodiments, the device body 3 is fixed to the grip portion 11. The length of the device body 3 is parallel to or perpendicular to the length of the grip portion 11. The housing of the device body 3 and the housing of the grip portion 11 can be integrally connected, or the housing of the device body 3 can be fastened to the grip portion 11 using screws or other fasteners.

[0059] Specifically, in some embodiments, Figure 2 and Figure 4 As shown, the operation key 13 is located on one side of the device body 3 near the scanning unit for user operation. The operation key 13 is located on the front of the holding portion 11, and can also be located on the side or back of the holding portion 11.

[0060] In some embodiments, as Figure 2 and Figure 4 As shown, the front of the holding portion 11 includes a first plane 111 and a second plane 112. The first plane 111 and the second plane 112 are both located on the front of the holding portion 11. The first plane 111 is located on the side of the holding portion 11 away from the scanning end of the holding portion 11, and the second plane 112 is located on the side of the holding portion 11 close to the scanning end of the holding portion 11. The first plane 111 is lower than the second plane 112, and the first plane 111 and the second plane 112 are connected to form a stepped surface 113. The device body 3 can be rotatably mounted on the first plane 111.

[0061] like Figure 2As shown, when the length direction of the device body 3 is parallel to the length direction of the scanning body 1, one side edge of the device body 3 along its width direction abuts against the step surface 113 to provide support force through the step surface 113, thereby improving the stability of the device body 3 during use.

[0062] The traditional learning device is limited by the size of the scanning body 1. The display screen is installed on the front of the scanning body 1 and is flush with the front of the scanning body 1. The size is small and it causes great damage to the user's eyes. The learning device provided by the present invention is Figure 1 and Figure 2 As shown, the width of the device body 3 is greater than that of the scanning body 1. The display screen of the device body 3 is configured to be wider to enhance the user's viewing experience and reduce eye damage. Taking the example of the device body 3 being rotatably mounted on the grip 11, when the device body 3 is rotated to the first position relative to the scanning body 1, the two longitudinal edges of the device body 3 are symmetrically arranged about the longitudinal centerline of the scanning body 1. This ensures the balance of the device body 3 during rotation and the aesthetics of the learning device.

[0063] Of course, the widths between the longitudinal edges of the device body 3 and the longitudinal centerline of the grip portion 11 can be different, as long as the device body 3 can rotate smoothly. Alternatively, the width of the device body 3 and the width of the grip portion 11 can be consistent. By partially exposing the device body 3 from the longitudinal edges of the scanning body 1, the device body 3 is ensured to have a wider width, thereby improving the user's viewing experience and reducing eye damage.

[0064] Taking the device body 3 as an example, which is rotatably mounted on the gripping portion 11, when the length direction of the device body 3 is consistent with the length direction of the scanning body 1, the top of the device body 3 is higher than the top of the scanning body 1. Figure 1 and Figure 2 As shown, the device body 3 is fixedly or rotatably mounted on the scanning body 1. When the length directions of the two are consistent, a portion of the device body 3 is exposed from the top surface of the holding portion 11 to ensure that the device body 3 has a longer length, so as to enhance the user's viewing experience and reduce the user's eye damage.

[0065] Furthermore, when the device body 3 is rotatably mounted on the scanning body 1, if the length direction of the device body 3 after rotation is perpendicular to the length direction of the scanning body 1, then, as shown in FIG. Figure 3 and Figure 4 As shown, the top of the device body 3 can be slightly lower than the top of the grip portion 11, or slightly higher than the top of the grip portion 11. As long as the device body 3 can rotate within the first plane 111 without interfering with the stepped surface 113, it will be sufficient.

[0066] The scanning body 1 and the device body 3 can share a power supply or have separate power supplies. In the case where the scanning body 1 and the device body 3 share a power supply, the power supply can be set in the scanning body 1 or the device body 3. For example, a first processor and a first power supply are installed in the scanning body 1, and the scanning unit and the first processor are both electrically connected to the first power supply. A second processor is installed in the device body 3, and the first processor and the display screen are both communicatively connected to the second processor. Thus, the scanning body 1 and the device body 3 share a power supply. Optionally, the first power supply is a rechargeable battery. The scanning body 1 is provided with a charging interface, which is electrically connected to the rechargeable battery so that the rechargeable battery can be charged by connecting an external power supply with the help of the charging interface.

[0067] Similarly, the scanning body 1 and the device body 3 can share a processor or have separate processors. In the case where the scanning body 1 and the device body 3 share a processor, the processor can be set in the scanning body 1 or the device body 3. For example, a first processor and a first power supply are installed in the scanning body 1, and the scanning unit and the first processor are both electrically connected to the first power supply. A second power supply is installed in the device body 3, and the first processor and the second power supply are electrically connected to the display screen, respectively. Thus, the scanning body 1 and the device body 3 share a processor. Optionally, the second power supply is a rechargeable battery, and the first power supply and the second power supply can be charged using the same charging interface or charging interfaces can be set separately.

[0068] In addition, a second processor and a second power supply can be installed in the device body 3 at the same time, thereby providing a power supply and a processor in the scanning body 1 and the device body 3 respectively.

[0069] In some embodiments, as Figure 1 and Figure 3 As shown, the learning device further includes a rear camera 5. The rear camera 5 is installed on the back of the scanning body 1.

[0070] Specifically, if Figure 1 As shown, the rear camera 5 is installed on the back of the holding portion 11 and is arranged close to the top of the holding portion 11 to avoid blocking the rear camera 5 when the user holds the holding portion 11, thereby improving the convenience of the learning device.

[0071] The rear camera 5 has a large field of view. When the content to be scanned is a long text, the user can quickly record or shoot the text through the rear camera 5. The rear camera 5 is communicatively connected to the first processor to send the recording or shooting information to the first processor. The first processor can translate the text and transmit the translation result to the device body 3 for display for the user to view. When the user starts the question search application on the device body 3, the shooting and entry of a single question can also be completed through the rear camera 5. In addition, the rear camera 5 can also be used as a camera for daily photo and video recording. Users can choose to use the rear camera 5, camera module 2 or scanning unit according to actual usage needs to improve the efficiency of the learning device.

[0072] Furthermore, in some embodiments, Figure 1 and Figure 3 As shown, a control key 14 is provided on the scanning body 1. The control key 14 is electrically connected to the rear camera 5. The control key 14 is configured to turn on or off the rear camera 5 in a triggered state.

[0073] Optionally, the control key 14 is a knob switch or a push switch. Figure 1 and Figure 3 As shown, the rear camera 5 and control keys 14 are both located on the back of the grip 11 for easy user operation. Furthermore, the control keys 14 are positioned on the back of the grip 11 to enhance the overall aesthetics of the learning device. Of course, the control keys 14 can also be positioned on the front or side of the grip 11. This is not a specific limitation in the present invention.

[0074] The control key 14 is electrically connected to the first processor, which is in turn electrically connected to the rear camera 5. By triggering the control key 14, the user can control the rear camera 5 to turn on or off via the first processor. If the display screen of the device body 3 is a touch screen, the rear camera 5 can also be turned on or off by touching the touch screen, which is very convenient.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
