[0034] The following will be described in detail Figures 1 to 6 The learning device of the utility model is described.

[0035] As Figure 1 and Figure 2 The utility model provides a kind of learning equipment, including: scanning main body 1 and equipment main body 2.

[0036] Scanning main body 1 includes holding part 11 and the scanning head 12 of retractable installation in one end of holding part 11.

[0041] Alternatively, the device main body 2 can be rotatably installed on the front surface of the holding part 11. Specifically, as shown in Figure 1 and Figure 2 , in the initial state, the length direction of the device main body 2 is parallel to the length direction of the holding part 11. By rotating or rotating the driving member 31 to drive the device main body 2, the length direction of the device main body 2 is perpendicular to the length direction of the holding part 11, thereby switching the position of the device main body 2 relative to the holding part 11, realizing the switching of the display screen between the vertical screen and the horizontal screen, and adapting to the use habits of different users.

[0042] The scanning main body 1 and the device main body 2 can share a power supply or are respectively provided with a power supply, in the case that the scanning main body 1 and the device main body 2 share a power supply, the power supply can be arranged in the scanning main body 1 or the device main body 2. Similarly, the scanning main body 1 and the device main body 2 can share a processor or are respectively provided with a processor. In the case that the scanning main body 1 and the device main body 2 share a processor, the processor can be arranged in the scanning main body 1 or the device main body 2.

[0043] Optionally, the scanning main body 1 is provided with a first processor and a first power supply, the scanning head 12 and the first processor are electrically connected with the first power supply. The device main body 2 is provided with a second processor, the second processor is electrically connected with the display screen. Thus, the scanning main body 1 and the device main body 2 share a power supply. Optionally, the first power supply is a rechargeable battery. The scanning main body 1 is provided with a charging interface, the charging interface is electrically connected with the rechargeable battery, so as to charge the rechargeable battery by connecting an external power supply with the charging interface.

[0044] Similarly, the scanning main body 1 and the device main body 2 can share a processor or are respectively provided with a processor. In the case that the scanning main body 1 and the device main body 2 share a processor, the processor can be arranged in the scanning main body 1 or the device main body 2. For example, the scanning main body 1 is provided with a first processor and a first power supply, the scanning head 12 and the first processor are electrically connected with the first power supply. The device main body 2 is provided with a second power supply, the first processor and the second power supply are electrically connected with the display screen. Thus, the scanning main body 1 and the device main body 2 share a processor. Optionally, the second power supply is a rechargeable battery, the first power supply and the second power supply can be charged by the same charging interface or are respectively provided with charging interfaces.

[0045] Optionally, the display screen is a touch screen, the user can input operation instructions through the touch screen, such as starting the application of searching for questions or searching for words, turning on or off the learning device, etc.

[0046] The utility model provides a kind of learning device, scanning head 12 can be scanned on the surface of scanning medium, device main body 2 is installed in holding portion 11 and is connected with scanning head 12 to realize information sharing, when needing to use scanning head 12, scanning head 12 is stretched out from scanning hole 111, to scan the content to be scanned;When scanning head 12 is used, scanning head 12 is received in holding portion 11, scanning head 12 is formed by holding portion 11 with physical protection, integrates scanning function on learning device, improves the use convenience of user.

[0047] Further, in some embodiments, the end of the holding portion 11 is hingedly connected to a sealing cover 16. As shown in Figure 1 and Figure 2 When the scanning head 12 is extended out of the holding portion 11, the sealing cover 16 is opened. As shown in Figure 3 and Figure 4As shown, the sealing cover 16 covers the scanning hole 111 when the scanning head 12 is retracted into the holding part 11.

[0048] Specifically, the sealing cover 16 is hinged to the scanning end of the holding part 11. When the scanning head 12 is extended out of the scanning hole 111, the scanning head 12 pushes the sealing cover 16, and the sealing cover 16 is opened. After the scanning head 12 is retracted into the scanning hole 111, the sealing cover 16 can be pushed by a reset member or manually to cover the scanning hole 111, thereby sealing the scanning head 12 inside the holding part 11 and further physically protecting the scanning head 12 to increase the service life of the learning device.

[0049] In some embodiments, as shown in Figure 1 and Figure 2 , there are two sealing covers 16. The two sealing covers 16 are symmetrically hinged to the scanning end of the holding part 11 along the sliding direction of the scanning head 12. The two sealing covers 16 are oppositely arranged in a double-door manner. Specifically, the two sides of the sealing cover 16 adjacent to the hinged edges are concave in the same direction, forming grooves on the sealing cover 16. When the scanning head 12 is extended out of the scanning hole 111, the scanning head 12 pushes the two sealing covers 16, and the two sealing covers 16 are opened at the same time. The grooves of the two sealing covers 16 are oppositely arranged. 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 groove walls of the two grooves, so that the scanning head 12 is not easy to deviate during scanning. After 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 part 11, thereby further physically protecting the scanning head 12 to increase the service life of the learning device.

[0050] The two sealing covers 16 are oppositely arranged in a double-door manner, which can clamp the scanning head 12 after the scanning head 12 is extended out of the scanning hole 111 to ensure the stability of the scanning head 12 during scanning, and can reduce the size of the sealing cover 16 along the length direction of the holding part 11 after the sealing cover 16 is opened, thereby avoiding that a single sealing cover blocks the scanning window 121 due to the excessive size and ensuring that the scanning head 12 has a better scanning field of view.

[0051] Specifically, as shown in Figure 5 , the sealing cover 16 is rotatably installed on the holding part 11 through a rotating shaft 17. A torsional spring 18 is sleeved on the rotating shaft 17, one end of the torsional spring 18 abuts against the sealing cover 16, and the other end abuts against the inner wall of the shell of the holding part 11.

[0052] The rotating shaft 17 is rotatably installed on the holding part 11 and fixedly connected with the sealing cover 16. Alternatively, the rotating shaft 17 is rotatably installed on the sealing cover 16 and fixedly connected with the holding part 11. The torsional spring 18 is sleeved on the rotating shaft 17, and the two ends of the torsional spring 18 abut against the holding part 11 and the sealing cover 16, respectively.

[0053] When the scanning head 12 is extended out of the scanning hole 111, the sealing cover 16 is in an open state, the torsion spring 18 accumulates energy, and the scanning head 12 is stably supported by the elastic force of the torsion spring 18. When the scanning head 12 is retracted into the holding portion 11, the sealing cover 16 is automatically closed on the scanning hole 111 under the elastic force of the torsion spring 18.

[0054] In some embodiments, as shown in Figure 5 and Figure 6 , the learning device further comprises a linear driving mechanism 3. The linear driving mechanism 3 is in driving connection with the scanning head 12. The linear driving mechanism 3 is installed in the interior of the holding portion 11, and the scanning head 12 is driven by the linear driving mechanism 3 to move linearly along the axial direction of the holding portion 11, so as to ensure that the scanning head 12 can be extended out of the scanning hole 111 or retracted into the scanning hole 111.

[0055] Alternatively, the scanning head 12 can be manually pushed to extend out of the scanning hole 111 or be retracted into the scanning hole 111. Optionally, the shell of the holding portion 11 is provided with a sliding hole extending along the length direction of the holding portion 11. The scanning head 12 is fixed with a sliding block matched with the sliding hole. The sliding block is accommodated in the sliding hole. By manually pushing the sliding block, the scanning head 12 can be extended or retracted.

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

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

[0058] The driving shaft of the rotary 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 scanning head 12 is driven by the nut 321 to move linearly along the axial direction of the screw 322, and thus the scanning head 12 can be extended out of the scanning hole 111 or retracted into the scanning hole 111.

[0059] Further, in some embodiments, as shown in Figure 5 and Figure 6As shown, the learning device further comprises a guide 4. One of the guide 4 and the scanning head 12 is provided with a guide block, and the other is provided with a guide slot. The guide block is slidably installed in the guide slot.

[0060] Specifically, the guide 4 is in the shape of a long strip. The guide 4 is fixed to the inside of the holding part 11 and close to one end of the scanning head 12. The length direction of the guide 4 is parallel to the length direction of the holding part 11. Optionally, the guide slot is provided on the guide 4 and extends along the length direction of the guide 4. The guide block is fixed to the side surface of the scanning head 12. The guide block is slidably installed in the guide slot to guide the smooth movement of the scanning head 12 when it is extended or retracted from the scanning hole 111.

[0061] Of course, the guide slot can also be provided on the scanning head 12, and the guide block can be provided on the guide 4, as long as the smooth movement of the scanning head 12 can be ensured.

[0062] Further, as shown in Figure 5 and Figure 6 , the learning device further comprises a guide seat 5. The inner end of the scanning head 12 is fixed to the guide seat 5. One end of the guide seat 5 is fixedly connected with the nut 321 in the screw rod 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 moved by the rotation driving part 31 and the screw rod assembly 32, the end of the guide seat 5 away from the guide 4 is fixedly connected with the nut 321 of the screw rod assembly 32 to drive the scanning head 12 to move back and forth. The end of the guide seat 5 away from the nut 321 is in contact with the guide 4, and the guide seat 5 can slide relative to the guide 4. By installing the guide seat 5 on the inner end of the scanning head 12, the length of the scanning head 12 extended from the device main body 2 can be extended without changing the specifications of the scanning head 12, and the transmission cooperation between the screw rod assembly 32 and the scanning head 12 can be enhanced, so that the scanning head 12 can be smoothly extended or retracted from the scanning hole 111.

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

[0065] Specifically, the device main body 2 can be rotatably installed on the scanning main body 1 by manual or driving means. When the device main body 2 is rotatably installed on the scanning main body 1 by driving means, as shown in Figure 2 and Figure 4As shown, the grip 11 is provided with an operation key 13. The operation key 13 is electrically connected to the drive unit. The operation key 13 is configured to control the rotation of the device body 2 by a preset angle when triggered. The operation key 13 is located on the front of the grip 11 and on the side of the device body 2 near the scanning end of the grip 11 for user operation.

[0066] For example, such as 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 which point the length direction of the device body 2 is parallel to the length direction of the grip part 11. When the user triggers operation key 13, the device body 2 rotates 90° relative to the scanning body 1 and moves to the first position. At this point, the length direction of the device body 2 is perpendicular to the length direction of the scanning body 1. When the user triggers operation key 13 again, the device body 2 rotates 90° in the opposite direction, and at this point, the device body 2 switches to the second position relative to the scanning body 1.

[0067] Optionally, the drive unit rotates the main body 2 of the device by a preset angle in a single rotation. The preset angle can be 90°, 30°, etc. In use, after the user triggers operation key 13, the drive unit automatically shuts off after each rotation of the main body 2 of the device by the preset angle. Thus, the user can control the drive unit by triggering operation key 13, thereby switching the main body 2 of the device between a first position and a second position.

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

[0069] like Figures 1 to 4 As shown, a portion of the device body 2 protrudes from the scanning body 1. Specifically, when the length direction of the device body 2 is parallel to the length direction of the grip 11, the top of the device body 2 protrudes from the top surface of the scanning body 1, allowing for the mounting of a larger display screen on the device body 2. Alternatively, the width of the device body 2 is greater than the width of the grip 11. For example, both sides of the device body 2 in its length direction protrude from the scanning body 1, and the two 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 of the two sides of the device body 2 in its length direction and the center line of the grip 11 along its length direction can also be different. By setting both the length and width of the device body 2 to be large, the screen size of the display screen can be increased, thereby improving the user's viewing experience and reducing eye strain.

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

[0071] Specifically, in this embodiment, the rear camera 6 is located on the back of the grip 11 and close to the end of the grip 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 communicatively connected to the first processor to send recorded or captured information. The first processor can translate the text and transmit the translation results to the main body 2 for display by the user, improving word extraction efficiency. Users can conveniently choose between the rear camera 6 or the scanning head 12 for word extraction according to their actual needs.

[0073] In addition, the rear camera 6 can also be used as a camera for everyday photos and videos.

[0074] Furthermore, such as Figure 2 As shown, a control button 14 is provided on the back of the grip 11. The control button 14 is electrically connected to the rear camera 6, and the control button 14 is configured to turn the rear camera 6 on or off when triggered.

[0075] Optionally, control button 14 can be a rotary switch or a push-button switch. A single trigger of control button 14 activates the rear camera 6 for taking pictures or recording videos, while triggering control button 14 again turns off the rear camera 6.

[0076] The control key 14 protrudes from the scanning body 1. Users can quickly locate the position of the control key 14 by using the protruding structure, and the protruding control key 14 can also help with holding the device.

[0077] 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.
