[0038] The following combination Figures 1 to 9 The learning device of the present invention is described.

[0039] The utility model provides a learning device, comprising:

[0040] The device body 1 has a through hole 11 on one side thereof.

[0041] The sealing cover 2 is hinged to the equipment body 1 .

[0042] The scanning head 3 is retractably mounted on the device body 1 .

[0043] like Figure 1 and Figure 2 As shown, when the scanning end of the scanning head 3 extends outward from the device body 1 , the sealing cover 2 is opened and the scanning head 3 extends out from the through hole 11 .

[0044] like Figure 3 and Figure 4 As shown, when the scanning head 3 is retracted into the device body 1 , the sealing cover 2 covers the through hole 11 .

[0045] The learning device provided by the present invention supports learning application functions such as word recitation, listening practice, and oral practice. A scanning head 3 is added to the device body 1 to scan and look up words through the scanning head 3 to realize the word lookup and translation function of the learning device. Specifically, optional, such as Figure 1 As shown, a through hole 11 is provided on one side of the device body 1 extending in the width direction. The through hole 11 connects the outside world and the interior of the device body 1. The scanning head 3 includes a shell, a scanning camera and a fill light. A scanning window 31 is provided at the end of the shell. The scanning window 31 is used to frame the content to be scanned during scanning. The scanning camera and the fill light are installed in the shell. The scanning camera is used to scan when the scanning head 3 slides on the scanning medium. The content scanned by the scanning camera is recognized by OCR and provides scanning data input for the scanning subject. The fill light is used to illuminate the scanning camera to ensure that the scanning camera obtains a clear word-picking image.

[0046] like Figure 2 As shown, a display screen 13 is mounted on the front of the device body 1. The display screen 13 is communicatively connected to the scanning head 3. Specifically, a processor is mounted within the device body 1. The scanning head 3 is electrically connected to the processor, which is in turn electrically connected to the display screen 13. The scanning head 3 transmits scanned information to the processor. The processor can translate the scanned information and transmit the translated information to the display screen 13 for display. Alternatively, the processor can transmit both the scanned information and the translated information to the display screen 13 for easy comparison and viewing by the user.

[0047] like Figure 1As shown, the sealing cover 2 is plate-shaped. One side of the sealing cover 2 is hinged to the side of the device body 1 where the through hole 11 is provided. Optionally, when the scanning head 3 extends from the through hole 11, the scanning head 3 pushes the sealing cover 2 to open the sealing cover 2 so that the scanning head 3 extends from the through hole 11. Alternatively, the sealing cover 2 is first opened with the help of a driving member, and the scanning head 3 extends after the sealing cover 2 is opened. After the scanning head 3 is retracted to the through hole 11, the sealing cover 2 can be pushed manually with the help of a reset member or manually to cover the through hole 11. The sealing cover 2 is used to seal the scanning head 3 inside the device body 1, thereby forming physical protection for the scanning head 3, increasing the service life of the learning device, and improving the coordination of the overall appearance of the learning device. Optionally, when the sealing cover 2 is covered on the through hole 11, the sealing cover 2 is flush with the device body 1 to ensure the aesthetics of the entire learning device.

[0048] When scanning is required, the sealing cover 2 is opened, and the scanning head 3 extends from the through-hole 11. As the scanning head 3 moves across the surface of the scanning medium, the scanning camera scans the content to be scanned. After use, the scanning head 3 is retracted and hidden within the through-hole 11. The sealing cover 2 is closed on the device body 1, providing protection for the scanning head 3 and making it easier for the user to store the learning device.

[0049] The present invention provides a learning device, in which a scanning head 3 is retractably mounted on a device body 1, and the scanning head 3 can scan while moving on the surface of a scanning medium, and display the scanning result with the help of the device body, thereby enriching the function of the learning device, and a sealing cover 2 is hinged to the device body 1, and when the scanning head 3 needs to be used, the scanning head 3 is extended from the through hole 11 to facilitate the use of the scanning head 3 for scanning; when the scanning head 3 is used, the scanning head 3 is retracted from the through hole 11 to the inside of the device body 1, and the sealing cover 2 covers the through hole 11, so that the scanning head 3 is sealed and accommodated in the device body 1, thereby forming physical protection for the scanning head 3, ensuring that the scanning head 3 is not easily damaged, and improving the user's convenience.

[0050] Specifically, in some embodiments, Figure 1 As shown, the sealing cover 2 is hinged to the device body 1 along one side of the width direction of the device body 1.

[0051] The size of the sealing cover 2 is adapted to the size of the through hole 11. Figure 2 As shown, when the sealing cover 2 is open, it fits against the back of the scanning head 3, ensuring the aesthetics of the learning device. It should be noted that when the sealing cover 2 is open, the extended length of the scanning head 3 is greater than the length of the sealing cover 2 along the length of the device body 1, ensuring that the sealing cover 2 does not block the scanning window 31, ensuring that the scanning head 3 has an optimal scanning field of view.

[0052] In other embodiments, the sealing cover 2 is hinged to the device body 1 at one side along the thickness direction of the device body 1. The two sealing covers 2 are arranged opposite to each other in a double-door style.

[0053] Specifically, the two sealing covers 2 are symmetrically hinged to the device body 1 along one side in the thickness direction of the device body 1 and along the sliding direction of the scanning head 3. When the sealing covers 2 are covered on the through hole 11, the two side edges of the sealing covers 2 along the width direction of the device body 1 are folded inward to form a groove. When the scanning head 3 extends from the through hole 11, the scanning head 3 pushes the two sealing covers 2, and the two sealing covers 2 are opened at the same time. At this time, the notches of the grooves of the two sealing covers 2 are arranged relative to each other, and the scanning head 3 is clamped between the two sealing covers 2. The opposite sides of the scanning head 3 are tightly fitted with the groove walls of the two grooves, respectively, thereby ensuring the stability of the scanning head 3 during scanning. When the scanning head 3 is retracted into the device body 1, the two sealing covers 2 are covered on the through hole 11, and the scanning head 3 is sealed and accommodated in the device body 1.

[0054] After the scanning head 3 extends out of the through hole 11, the two sealing covers 2 can clamp the scanning head 3 to ensure that the scanning head 3 can slide smoothly on the surface of the scanning medium. At the same time, by arranging the two sealing covers 2 in a double-door type relative to each other, the size of the sealing cover 2 along the length direction of the device body 1 can be reduced, avoiding the setting of a single sealing cover that makes the sealing cover too large and blocks the scanning window 31, which helps to achieve the miniaturization of the scanning head 3.

[0055] Specifically, the sealing cover 2 is rotatably mounted on the device body 1 via a rotating shaft 4. A torsion spring 5 is sleeved on the rotating shaft 4. One end of the torsion spring 5 abuts against the sealing cover 2, and the other end abuts against the inner wall of the device body 1.

[0056] There are two rotating shafts 4, one on each side of the sealing cover 2. A torsion spring 5 is sleeved around one of the two rotating shafts 4, or both rotating shafts 4 are sleeved with a torsion spring 5. The torsion springs 5 ​​ensure that the sealing cover 2 remains stably closed.

[0057] In an optional embodiment, the rotating shaft 4 is fixed to the equipment body 1, and the sealing cover 2 is provided with a rotating shaft hole, and the rotating shaft 4 can be rotatably inserted into the rotating shaft hole.

[0058] In another optional embodiment, Figure 5As shown, the sealing cover 2 includes a base 21 and a cover body 22. The base 21 is provided with a connecting hole 211, and the cover body 22 is plugged and fixed to the connecting hole 211. Specifically, the base 21 has a stepped surface, and the through hole 11 is a stepped hole. When the sealing cover 2 is covered on the through hole 11, the stepped surface of the base 21 is abutted against the stepped surface of the stepped hole. A support ear 221 is provided on one side of the cover body 22, and the support ear 221 is provided with a first arc-shaped groove, and the base 21 is provided with a second arc-shaped groove. After the cover body 22 is connected to the base 21, the first arc-shaped groove and the second arc-shaped groove are connected to form a shaft hole. One end of the shaft 4 is plugged and fixed to the shaft hole, and the other end of the shaft 4 passes through the base 21 and rotates with the device body 1.

[0059] When the scanning head 3 needs to be used, the scanning head 3 passes through the through hole 11, and the scanning head 3 pushes the sealing cover 2 to open the sealing cover 2, and the torsion spring 5 accumulates force; when the scanning head 3 is retracted into the device body 1, the torsion spring 5 releases the elastic force to drive the sealing cover 2 to cover the through hole 11, and is limited by the stepped surface of the base 21 and the stepped surface of the stepped hole.

[0060] In some embodiments, as Figure 6 、 Figure 7 and Figure 8 As shown, the learning device further includes a linear drive mechanism 6. The linear drive mechanism 6 is in transmission connection with the scanning head 3.

[0061] The linear drive mechanism 6 is installed inside the device body 1 , and drives the scanning head 3 to move linearly along the length direction of the device body 1 to ensure that the scanning head 3 can extend out of the through hole 11 or retract into the through hole 11 .

[0062] Alternatively, the scanning head 3 can be manually pushed to extend from or retract into the through hole 11. Optionally, the housing of the device body 1 is provided with a sliding hole extending along the length of the device body 1. A slider adapted to fit within the sliding hole is secured to the scanning head 3, and the slider extends through the sliding hole. The scanning head 3 can be extended or retracted by manually pushing the slider.

[0063] Specifically, in some embodiments, Figure 6 、 Figure 7 and Figure 8 As shown, the linear drive mechanism 6 includes a rotary drive member 61 and a lead screw assembly 62. The scanning head 3 is fixedly connected to a nut 621 in the lead screw assembly 62. The rotary drive member 61 is transmission-connected to a lead screw 622 in the lead screw assembly 62.

[0064] It is understandable that the rotary drive member 61 and the lead screw assembly 62 are both located in the device body 1 and close to one end of the through hole 11. The rotary drive member 61 can be a stepper motor or a servo motor. The axis of the lead screw 622 of the lead screw assembly 62 is parallel to the extension direction of the through hole 11. When the drive shaft of the rotary drive member 61 and the lead screw 622 of the lead screw assembly 62 are coaxial, the drive shaft of the rotary drive member 61 can be directly fixedly connected to the lead screw 622. When the drive shaft of the rotary drive member 61 and the lead screw 622 of the lead screw assembly 62 are not coaxial, the drive shaft of the rotary drive member 61 and the lead screw 622 of the lead screw assembly 62 can be connected by transmission through a gear system.

[0065] When the rotary drive member 61 drives the lead screw 622 to rotate, the scanning head 3 moves linearly along the axial direction of the lead screw 622 along with the nut 621 of the lead screw assembly 62, thereby allowing the scanning head 3 to extend out of the through hole 11 or retract into the through hole 11.

[0066] like Figure 6 As shown, a mounting groove 12 is provided inside the device body 1 . The rotary drive member 61 is partially received in the mounting groove 12 , thereby firmly fixing the rotary drive member 61 in the device body 1 .

[0067] In some embodiments, as Figure 6 、 Figure 7 and Figure 8 As shown, the learning device further includes a guide base 8. The inner end of the scanning head 3 is fixed to the guide base 8. One end of the guide base 8 is fixedly connected to the nut 621 in the screw assembly 62.

[0068] Specifically, when the scanning head 3 is driven to move by the rotating drive member 61 and the lead screw assembly 62, the end of the guide base 8 away from the guide plate 7 is fixedly connected to the nut 621 of the lead screw assembly 62, thereby driving the scanning head 3 to move back and forth. The end of the guide base 8 away from the nut 621 is in contact with the guide plate 7, and the guide base 8 can slide relative to the guide plate 7. By installing the guide base 8 on the inner end of the scanning head 3, the length of the scanning head 3 extending out of the device body can be extended without changing the specifications of the scanning head 3. The transmission coordination between the lead screw assembly 62 and the scanning head 3 can also be strengthened, allowing the scanning head 3 to smoothly extend or retract into the through hole 11.

[0069] Furthermore, in some embodiments, Figure 6 、 Figure 7 and Figure 8 As shown, the learning device further includes a guide plate 7. The guide plate 7 is in contact with the side wall of the scanning head 3.

[0070] Specifically, the guide plate 7 is fixed inside the device body 1. The length of the guide plate 7 is parallel to the extension and retraction direction of the scanning head 3. When the scanning head 3 is extended or retracted relative to the device body 1, the sidewalls of the scanning head 3 contact the guide plate 7 and slide along the surface of the guide plate 7, thereby guiding the scanning head 3 to move smoothly when extending or retracting the through hole 11.

[0071] In some other embodiments, Figure 7 and Figure 8 As shown, one of the inner wall of the shell of the device body 1 and the scanning head 3 is provided with a guide rail 14, and the other is provided with a guide groove, and the guide rail 14 is slidably matched with the guide groove.

[0072] Optionally, the guide rail 14 is fixed to the inner wall of the housing of the device body 1, and correspondingly, the scanning head 3 is provided with a guide groove, and the guide rail 14 can be slidably accommodated in the guide groove. Figure 7 As shown, the length direction of the guide rail 14 is parallel to the length direction of the device body 1. When the scanning head 3 extends out of the through hole 11, the human hand can hold the device body 1 along the side of the length direction for scanning, which is more convenient to hold than holding the device body 1 along the side of the width direction.

[0073] Of course, guide rails 14 may be provided on the side of the scanning head 3 and guide grooves may be provided on the inner wall of the device body 1 , as long as the scanning head 3 can be ensured to move smoothly.

[0074] 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. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
