[0034] The following combination Figures 1 to 6 The learning device of the present invention is described.

[0035] like Figure 1 and Figure 2 As shown, the utility model provides a learning device, including: a scanning body 1 and a device body 2.

[0036] The scanning body 1 includes a holding portion 11 and a scanning head 12 which is retractably mounted on one end of the holding portion 11. Figure 3As shown, the holding portion 11 is provided with a scanning hole 111 for the scanning head 12 to extend out. The device body 2 has a display screen, and the device body 2 is mounted on the holding portion 11 and is in communication connection with the scanning head 12.

[0037] 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 2 can realize various functions of a traditional learning machine, and the scanning body 1 is integrated on the device body 2, so that the learning machine has a scanning function, thereby improving the integration of the device.

[0038] Specifically, the holding portion 11 is in the shape of an elongated strip, and is intended to be held by a human hand. The bottom of the holding portion 11 is the scanning end of the scanning body 1. The scanning hole 111 is located at the scanning end of the scanning body 1, connecting the outside world and the interior of the holding portion 11. A scanning window 121 is provided at the end of the scanning head 12, and the scanning window 121 is used to frame the content to be scanned during scanning. The scanning head 12 has a scanning camera and a fill light, and the scanning camera is used to scan when the scanning body 1 slides along the surface of the scanning medium. The fill light is used to illuminate the scanning camera to ensure that the scanning camera obtains a clear word-picking picture. A power button 15 is provided on the side of the holding portion 11, and the user triggers the power button 15 to turn the learning device on or off.

[0039] When the scanning head 12 is in use, the scanning end of the scanning head 12 extends out of the scanning hole 111, allowing the user to hold the grip 11 for scanning operations. After use, the scanning head 12 is retracted and hidden within the grip 11. The grip 11 protects the scanning head 12, preventing it from protruding and being damaged, while also making it easier for the user to store the learning device.

[0040] Optionally, the device body 2 can be fixed to the front of the grip portion 11 by means of screws or other fasteners, and the length direction of the device body 2 is parallel or perpendicular to the length direction of the grip portion 11. Figure 1 and Figure 2 As shown, the device body 2 is fixedly mounted on the holding portion 11 , and the length direction of the device body 2 is consistent with the length direction of the holding portion 11 .

[0041] Alternatively, the device body 2 is rotatably mounted on the front of the grip portion 11. Specifically, Figure 1 and Figure 2 As shown, in the initial state, the length direction of the device body 2 is parallel to the length direction of the grip portion 11. By manually rotating or rotating the driving member 31, the device body 2 is driven so that the length direction of the device body 2 and the length direction of the grip portion 11 are perpendicular, thereby switching the position of the device body 2 relative to the grip portion 11 and switching the display screen between portrait and landscape modes, thereby adapting to the usage habits of different users.

[0042] The scanning body 1 and the device body 2 may share a power supply or have separate power supplies. If the scanning body 1 and the device body 2 share a power supply, the power supply may be located in either the scanning body 1 or the device body 2. Similarly, the scanning body 1 and the device body 2 may share a processor or have separate processors. If the scanning body 1 and the device body 2 share a processor, the processor may be located in either the scanning body 1 or the device body 2.

[0043] Optionally, a first processor and a first power supply are installed in the scanning body 1, and the scanning head 12 and the first processor are both electrically connected to the first power supply. A second processor is installed in the device body 2, and the second processor is electrically connected to the display screen. This allows the scanning body 1 and the device body 2 to share a common power supply. Optionally, the first power supply is a rechargeable battery. The scanning body 1 is provided with a charging port, which is electrically connected to the rechargeable battery, so that the rechargeable battery can be charged by connecting to an external power source via the charging port.

[0044] Similarly, the scanning body 1 and the device body 2 can share a processor or have separate processors. In the case where the scanning body 1 and the device body 2 share a processor, the processor can be set in either the scanning body 1 or the device body 2. For example, a first processor and a first power supply are installed in the scanning body 1, and the scanning head 12 and the first processor are both electrically connected to the first power supply. A second power supply is installed in the device body 2, 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 2 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.

[0045] Optionally, the display screen is a touch screen, and the user can input operating instructions through the touch screen, such as starting applications such as question search or word lookup, turning on or off learning equipment, etc.

[0046] The present invention provides a learning device, in which a scanning head 12 can scan the surface of a scanning medium. The device body 2 is mounted on a holding portion 11 and is in communication with the scanning head 12 to realize information sharing. When the scanning head 12 needs to be used, the scanning head 12 extends from a scanning hole 111 to scan the content to be scanned; when the scanning head 12 is used, the scanning head 12 is retracted into the holding portion 11, and the holding portion 11 is used to form physical protection for the scanning head 12. The scanning function is integrated into the learning device, thereby improving the user's convenience.

[0047] Furthermore, in some embodiments, the end of the grip portion 11 is hinged to the sealing cover 16. Figure 1 and Figure 2 As shown in FIG, when the scanning head 12 is extended out of the holding portion 11, the sealing cover 16 is opened. Figure 3 and Figure 4As shown, when the scanning head 12 is retracted into the holding portion 11 , the sealing cover 16 covers the scanning hole 111 .

[0048] Specifically, the sealing cover 16 is hingedly connected to the scanning end of the grip 11. When the scanning head 12 extends from the scanning aperture 111, it pushes the sealing cover 16, causing it to open. Once the scanning head 12 is retracted into the scanning aperture 111, the sealing cover 16 can be manually pushed with the aid of a reset member or manually, closing the scanning aperture 111. This seals the scanning head 12 within the grip 11, further physically protecting it and extending the lifespan of the learning device.

[0049] In some embodiments, as Figure 1 and Figure 2 As shown, there are two sealing covers 16. The two sealing covers 16 are symmetrically hinged to the scanning end of the holding portion 11 along the sliding direction of the scanning head 12. The two sealing covers 16 are arranged opposite each other in a double-door style. Specifically, the two side edges of the sealing covers 16 adjacent to the hinged edge are folded in the same direction, forming grooves on the sealing covers 16. When the scanning head 12 extends from the scanning hole 111, the scanning head 12 pushes the two sealing covers 16, and the two sealing covers 16 open simultaneously. The notches of the grooves of the two sealing covers 16 are arranged opposite each other. At this time, the scanning head 12 is clamped between the two sealing covers 16, and the opposite sides of the scanning head 12 are tightly fitted with the walls of the two grooves, making it less likely for the scanning head 12 to deflect during scanning. When the scanning head 12 is retracted into the scanning hole 111, the two sealing covers 16 cover the scanning hole 111 to seal the scanning head 12 inside the holding portion 11, thereby further providing physical protection for the scanning head 12 and increasing the service life of the learning device.

[0050] The two sealing covers 16 are arranged opposite to each other in a double-door style, which can not only clamp the scanning head 12 after the scanning head 12 extends out of the scanning hole 111 to ensure the stability of the scanning head 12 during scanning, but also reduce the size of the sealing cover 16 along the length direction of the holding part 11 after it is opened, avoiding a single sealing cover from blocking the scanning window 121 due to its excessive size, thereby ensuring that the scanning head 12 has a better scanning field of view.

[0051] Specifically, if Figure 5 As shown, the sealing cover 16 is rotatably mounted on the holding portion 11 via a rotating shaft 17. A torsion spring 18 is sleeved on the rotating shaft 17, one end of the torsion spring 18 abuts against the sealing cover 16, and the other end abuts against the inner wall of the housing of the holding portion 11.

[0052] The rotating shaft 17 is rotatably mounted on the grip portion 11 and fixedly connected to the sealing cover 16. Alternatively, the rotating shaft 17 is rotatably mounted on the sealing cover 16 and fixedly connected to the grip portion 11. A torsion spring 18 is sleeved on the rotating shaft 17, with its two ends respectively abutting the grip portion 11 and the sealing cover 16.

[0053] When the scanning head 12 extends out of the scanning aperture 111, the sealing cover 16 is in the open position, and the torsion spring 18 accumulates energy, and the elastic force of the torsion spring 18 stably supports the scanning head 12. When the scanning head 12 is retracted into the grip 11, the elastic force of the torsion spring 18 automatically closes the sealing cover 16 over the scanning aperture 111.

[0054] In some embodiments, as Figure 5 and Figure 6 As shown, the learning device further includes a linear drive mechanism 3. The linear drive mechanism 3 is in transmission connection with the scanning head 12. The linear drive mechanism 3 is mounted within the holding portion 11 and drives the scanning head 12 to move linearly along the axial direction of the holding portion 11, ensuring that the scanning head 12 can extend from or retract into the scanning aperture 111.

[0055] Alternatively, the scanning head 12 can be manually pushed to extend from or retract into the scanning aperture 111. Optionally, the housing of the grip portion 11 is provided with a sliding hole extending along the length of the grip portion 11. A slider adapted to fit within the sliding hole is secured to the scanning head 12. The slider is received within the sliding hole. Manually pushing the slider allows the scanning head 12 to be extended or retracted.

[0056] Specifically, in some embodiments, Figure 5 and Figure 6 As shown, the linear drive mechanism 3 includes a rotary drive member 31 and a lead screw assembly 32. The scanning head 12 is fixedly connected to a nut 321 in the lead screw assembly 32, and the rotary drive member 31 is in transmission connection with a lead screw 322 in the lead screw assembly 32.

[0057] It is understandable that the rotary drive member 31 and the lead screw assembly 32 are both located in the holding portion 11 and close to the scanning hole 111. The rotary drive member 31 can be a stepper motor or a servo motor. The axis of the lead screw 322 in the lead screw assembly 32 is consistent with the telescopic direction of the scanning head 12. The drive shaft of the rotary drive member 31 can be directly or indirectly connected to the lead screw in the lead screw assembly 32. For example, the drive shaft of the rotary drive member 31 is directly and fixedly connected to the lead screw 322. For another example, the drive shaft of the rotary drive member 31 is connected to the lead screw 322 in the lead screw assembly 32 through a gear system.

[0058] The driving shaft of the rotating driving member 31 drives the screw 322 to rotate, and the scanning head 12 is fixed to the nut 321 of the screw assembly 32, so that the nut 321 drives the scanning head 12 to move linearly along the axial direction of the screw 322, thereby allowing the scanning head 12 to extend out of the scanning hole 111 or retract into the scanning hole 111.

[0059] Furthermore, in some embodiments, Figure 5 and Figure 6As shown, the learning device further comprises a guide member 4. One of the guide member 4 and the scanning head 12 is provided with a guide block, and the other is provided with a guide groove, in which the guide block can be slidably mounted.

[0060] Specifically, the guide member 4 is in the shape of an elongated strip. The guide member 4 is fixed inside the holding portion 11 and is close to one end of the scanning head 12. The length direction of the guide member 4 is parallel to the length direction of the holding portion 11. Optionally, a guide groove is provided in the guide member 4 and extends along the length direction of the guide member 4. The guide block is fixed to the side of the scanning head 12. The guide block is slidably provided in the guide groove to guide the scanning head 12 to move smoothly when extending or retracting the scanning aperture 111.

[0061] Of course, a guide groove may be provided on the scanning head 12 and a guide block may be provided on the guide member 4, as long as it is ensured that the scanning head 12 can move smoothly.

[0062] Furthermore, if Figure 5 and Figure 6 As shown, the learning device further includes a guide base 5. The inner end of the scanning head 12 is fixed to the guide base 5. One end of the guide base 5 is fixedly connected to the nut 321 in the screw assembly 32. The inner end of the scanning head 12 refers to the non-scanning end of the scanning head 12.

[0063] Specifically, when the scanning head 12 is driven to move by the rotating drive member 31 and the lead screw assembly 32, the end of the guide base 5 away from the guide member 4 is fixedly connected to the nut 321 of the lead screw assembly 32, thereby driving the scanning head 12 to move back and forth. The end of the guide base 5 away from the nut 321 is in contact with the guide member 4, and the guide base 5 can slide relative to the guide member 4. By installing the guide base 5 on the inner end of the scanning head 12, the length of the scanning head 12 extending from the device body 2 can be extended without changing the specifications of the scanning head 12. The transmission coordination between the lead screw assembly 32 and the scanning head 12 can also be strengthened, allowing the scanning head 12 to smoothly extend or retract into the scanning aperture 111.

[0064] In some embodiments, the device body 2 can be rotatably mounted on the grip portion 11. When the device body 2 is rotated to the first position relative to the grip portion 11, the length direction of the device body 2 is perpendicular to the length direction of the grip portion 11. Figures 1 to 4 As shown, when the device body 2 is rotated to the second position relative to the holding portion 11, the length direction of the device body 2 is parallel to the length direction of the holding portion 11, and the top of the device body 2 is higher than the top of the holding portion 11.

[0065] Specifically, the device body 2 can be rotatably mounted on the scanning body 1 manually or by a driving member. In the case where the device body 2 can be rotatably mounted on the scanning body 1 by a driving member, as shown in FIG. Figure 2 and Figure 4As shown, the grip portion 11 is provided with an operation key 13. The operation key 13 is electrically connected to the drive element. When triggered, the operation key 13 is configured to control the rotation of the device body 2 to a predetermined angle. The operation key 13 is located on the front of the grip portion 11, on the side of the device body 2 near the scanning end of the grip portion 11, for easy user operation.

[0066] For example, Figures 1 to 4 As shown, the initial position of the device body 2 relative to the scanning body 1 is the second position. At this time, the length direction of the device body 2 is parallel to the length direction of the grip portion 11. The user triggers the operation key 13, and the device body 2 rotates 90° relative to the scanning body 1 and moves to the first position. At this time, the length direction of the device body 2 is perpendicular to the length direction of the scanning body 1. The user triggers the operation key 13 again, and the device body 2 rotates 90° in the opposite direction. At this time, the device body 2 switches to the second position relative to the scanning body 1.

[0067] Optionally, the driver drives the device body 2 to rotate a preset angle. The preset angle can be 90°, 30°, or the like. During use, after the user triggers the operation key 13, the driver automatically turns off each time the device body 2 rotates the preset angle. Thus, the user can control the driver by triggering the operation key 13, thereby switching the device body 2 between the first position and the second position.

[0068] By rotatably mounting the device body 2 on the scanning body 1, the display screen of the device body 2 can be switched between portrait and landscape to adapt to different usage habits of users, which is highly convenient and improves the user experience of the learning device.

[0069] like Figures 1 to 4 As shown, a portion of the device body 2 is exposed from the scanning body 1. Specifically, when the length direction of the device body 2 is parallel to the length direction of the holding portion 11, the top of the device body 2 is exposed from the top surface of the scanning body 1, so that a display screen of a longer length can be installed on the device body 2. Alternatively, the width of the device body 2 is greater than the width of the holding portion 11. For example, both sides of the device body 2 in its length direction are exposed from the scanning body 1, and the both sides of the device body 2 in its length direction are symmetrically arranged about the center line of the scanning body 1 along its length direction to ensure the aesthetics of the learning device. Of course, the widths between the both sides of the device body 2 in its length direction and the center line of the holding portion 11 along its length direction may also be different. By setting both the length and width of the device body 2 to be larger, the screen size of the display screen can be increased, so as to enhance the user's viewing experience and reduce eye damage to the user.

[0070] In some embodiments, as Figure 2 and Figure 3As shown, the learning device further includes a rear camera 6. The rear camera 6 is mounted on the back of the holding portion 11.

[0071] Specifically, in this embodiment, the rear camera 6 is located on the back of the holding portion 11 and close to the end of the holding portion 11 away from the scanning end. The rear camera 6 has a large field of view. When the content to be scanned is a large text, the user can quickly record or photograph the text through the rear camera 6.

[0072] The rear camera 6 is in communication with the first processor to transmit recorded or photographed information to the first processor. The first processor can translate the text and transmit the translation results to the device body 2 for display by the user, thereby improving word retrieval efficiency. Users can conveniently select either the rear camera 6 or the scanning head 12 for word retrieval based on their actual needs.

[0073] In addition, the rear camera 6 can also be used as a camera for daily photo and video recording.

[0074] Furthermore, if Figure 2 As shown, a control key 14 is provided on the back of the grip portion 11. The control key 14 is electrically connected to the rear camera 6, and the control key 14 is configured to turn on or off the rear camera 6 in a triggered state.

[0075] Optionally, the control key 14 is a rotary switch or a push switch. Triggering the control key 14 once starts the rear camera 6 to take a picture or record a video, and triggering the control key 14 again turns off the rear camera 6.

[0076] The control key 14 is protruded from the scanning body 1 , and the user can quickly locate the position of the control key 14 with the help of the protruding structure when using it, and can also use the protruding control key 14 to assist in holding.

[0077] 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.
