[0032] The following combination Figure 1-Figure 3 The learning device of the present invention is described.

[0033] like Figure 1 As shown, the utility model provides a learning device, comprising:

[0034] 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.

[0035] The camera module 2 extends outward from the other end of the holding portion 11 and can rotate relative to the holding portion 11 .

[0036] The device body 3 is mounted on the holding portion 11 and is in communication connection with the scanning unit.

[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 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.

[0038] It is understandable that if Figure 1 As shown, the bottom of the holding portion 11 is the scanning end of the holding portion 11. A scanning window 12 is provided at the bottom of the holding portion 11, and the scanning window 12 is used to frame the content to be scanned during scanning. 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.

[0039] The device body 3 is fixedly or rotatably mounted on the front of the grip 11. The device body 3 is located at the top of the grip 11, that is, at the end of the grip 11 away from the scanning unit. Optionally, a portion of the device body 3 is exposed outside the scanning unit 1 to increase the size of the display screen on the device body 3, improve 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.

[0040] In some embodiments, the device body 3 can be fixedly mounted to the grip portion 11. The length of the device body 3 can be parallel or perpendicular to the length of the grip portion 11, or the two can be arranged at an acute angle. In other embodiments, the device body 3 can be rotatably mounted at the end of the grip portion 11 away from the scanning unit, for example, by manually or automatically adjusting the position of the device body 3 relative to the scanning body 1.

[0041] 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 and input other operation instructions through the touch screen.

[0042] like Figure 1 and Figure 2As shown, the camera module 2 is rotatably mounted on the top of the holding portion 11. Optionally, the camera module 2 is mounted on the top surface of the holding portion 11. The camera module 2 is exposed from the holding portion 11 to ensure that the camera module 2 has a larger shooting field of view. When the length direction of the device body 3 is perpendicular to the length direction of the holding portion 11, the top surface of the device body 3 is slightly lower than the top surface of the holding portion 11, or is flush with the top surface of the holding portion 11 to ensure that the device body 3 does not block the forward field of view of the camera module 2. When the length direction of the device body 3 is parallel to the length direction of the holding portion 11, the top of the device body 3 can be exposed from the top of the holding portion 11 to expand the length of the display screen of the device body 3, but it is necessary to ensure that the portion of the device body 3 exposed from the holding portion 11 does not block the shooting field of view of the camera module 2.

[0043] By controlling the rotation angle of the camera module 2, the camera module 2 can simultaneously have front and rear camera functions. Specifically, when the camera module 2 is in the initial state, the camera module 2's field of view faces the front of the learning device, and in this case, the camera module 2 functions as a front camera. The camera module 2 can be rotated 180° so that the camera module 2's field of view faces the rear of the grip portion 11, and in this case, the camera module 2 functions as a rear camera.

[0044] When the medium to be scanned is a large text, the user can quickly record or shoot the text through the camera module 2 to improve the efficiency of word retrieval. In addition, the camera module 2 can also be used as a camera for daily photo taking and video recording.

[0045] 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, the scanning unit can scan the surface of a scanning medium, a camera module 2 extends outward from the other end of the holding portion 11 and can rotate relative to the holding portion 11, so as to ensure that the camera module 2 has a larger shooting field of view, and by controlling the rotation of the camera module 2, the camera module 2 can switch between the front camera function and the rear camera function, thereby reducing the number of cameras arranged in the learning device; the device body 3 is installed on the holding portion 11, and is communicated with the scanning unit to realize information sharing between the scanning body 1 and the device body 3, thereby integrating the scanning function and the photo-taking function on the learning device, enriching the function of the scanning device, and improving the user's convenience.

[0046] Specifically, if Figure 3 As shown, in some embodiments, the learning device further includes a rotary drive member 4, a transmission shaft 5, and a mounting base 6. The camera module 2 is rotatably received in the mounting base 6. The camera module 2 is fixedly connected to the transmission shaft 5. The transmission shaft 5 is rotatably inserted into the mounting base 6. The rotary drive member 4 is in driving connection with the transmission shaft 5.

[0047] like Figure 3As shown, the mounting base 6 is fixed to the center of the top of the grip portion 11 and extends outward from the grip portion 11. The mounting base 6 can also be fixed to the top edge of the grip portion 11. The mounting base 6 and the outer shell of the grip portion 11 can be detachably connected, or the mounting base 6 and the outer shell of the grip portion 11 can be integrally connected. The camera module 2 is accommodated in the mounting base 6 and can rotate relative to the mounting base 6.

[0048] Specifically, the rotary drive member 4 is fixedly mounted within the grip portion 11. The axis of the transmission shaft 5 is arranged parallel to or coincident with the length of the grip portion 11. The transmission shaft 5 passes through the mounting base 6 and is rotatable relative to the mounting base 6. Optionally, the rotary drive member 4 is a stepper motor or a servo motor.

[0049] The camera module 2 includes a camera and a protective housing. The camera is fixed to the protective housing. The protective housing is fitted over a transmission shaft 5, or the outer wall of the protective housing is fixed to the transmission shaft 5, thereby achieving a fixed connection between the camera module 2 and the transmission shaft 5. The rotary drive member 4 is in driving connection with the transmission shaft 5 to drive the transmission shaft 5 to rotate, which in turn drives the camera module 2 to rotate, thereby enabling the camera module 2 to switch between front and rear camera functions.

[0050] Optionally, the rotary drive member 4 can drive the camera module 2 to rotate a preset angle in a single time. For example, if the preset angle is 180°, the rotary drive member 4 can drive the camera module 2 to rotate 180° in a single time to switch the camera module 2 between the front camera function and the rear camera function.

[0051] Furthermore, in some embodiments, Figure 3 As shown, the learning device further includes a first gear 7 and a second gear 8. The first gear 7 is sleeved on the transmission shaft 5. The second gear 8 is sleeved on the drive shaft 41 of the rotary drive member 4, and the first gear 7 and the second gear 8 are meshed.

[0052] Specifically, the first gear 7 and the second gear 8 are both mounted inside the grip portion 11. The drive shaft 41 of the rotary drive member 4 drives the second gear 8 to rotate, and the first gear 7 and the second gear 8 engage, and the second gear 8 drives the first gear 7 to rotate. The first gear 7 is sleeved on the transmission shaft 5, and the first gear 7 drives the transmission shaft 5 to rotate, thereby achieving a transmission connection between the rotary drive member 4 and the transmission shaft 5.

[0053] Alternatively, under the premise of achieving a reasonable layout of the internal structure of the grip portion 11, the transmission shaft 5 can also be directly connected to the driving end of the rotary drive member 4, and the transmission shaft 5 can be directly driven by the rotary drive member 4. The present invention does not make any specific restrictions on this.

[0054] like Figure 3As shown, the mounting base 6 includes a first base body 61 and a second base body 62. One end of the first base body 61 is located within the grip portion 11 and is fixedly connected to the grip portion 11. A first through hole 611 is defined in the portion of the first base body 61 located outside the grip portion 11. A second through hole 621 is defined at the other end of the second base body 62. The first base body 61 and the second base body 62 are connected such that the first through hole 611 and the second through hole 621 communicate with each other to form a receiving hole, within which the camera module 2 is mounted.

[0055] Specifically, if Figure 3 As shown, the portion of the first base 61 located inside the gripping portion 11 can be fastened to the gripping portion 11 by means of screws or other fasteners. The first through hole 611 is provided outside the first base 61 where the gripping portion 11 is exposed.

[0056] A second through hole 621 is provided in the second base 62. When the first base 61 and the second base 62 are fixedly connected by a snap or fastener, the first through hole 611 and the second through hole 621 communicate to form a receiving hole. Optionally, the camera module 2 is fixed to the transmission shaft 5 and received in the receiving hole. Of course, it is also possible to omit the mounting base and directly place the camera module 2 outside the grip 11, connecting it to the rotating drive member 4 inside the grip 11 via a rotating shaft or directly rotatably connected to the outer shell of the grip 11.

[0057] In some embodiments, the device body 3 can be rotatably mounted on the front of the scanning body 1. 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. Specifically, 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 parallel to the length direction of the scanning body 1. Figure 1 and Figure 2 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 .

[0058] By rotatably mounting the device body 3 on the scanning body 1 , the display screen of 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.

[0059] The device body 3 is mounted on the scanning body 1 and can be rotated manually or automatically. For example, the device body 3 can be rotatably mounted on the scanning body 1 via a drive member. An operation key 13 is provided on the scanning body 1. The operation key 13 is electrically connected to the drive member. When triggered, the operation key 13 is configured to control the rotation of the device body 3 to a predetermined angle.

[0060] 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.

[0061] like 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.

[0062] Optionally, the driving member drives the device body 3 to rotate a preset angle once. During 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. Optionally, the preset angle of each rotation of the device body 3 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° along the first direction relative to the scanning body 1 to the second position. The first direction can be clockwise or counterclockwise. At this time, if 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° relative to the scanning body 1 in the opposite direction of the first direction, 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 specific limitations on this.

[0063] Specifically, in some embodiments, Figure 2 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] In some embodiments, as Figure 1 As shown, the learning device further includes a rear camera 9. The rear camera 9 is installed on the back of the scanning body 1.

[0068] Specifically, if Figure 1 As shown, the rear camera 9 is installed on the back of the holding part 11 and is arranged close to the top of the holding part 11 to prevent the rear camera 9 from being blocked when the user holds the holding part 11, thereby improving the convenience of the learning device.

[0069] The rear camera 9 has a large field of view. When the content to be scanned is a long text, the user can quickly record or take a picture of the text through the rear camera 9 to improve the efficiency of word retrieval.

[0070] The rear camera 9 is connected to the first processor in communication to send recording or shooting information to the first processor. The first processor can translate the text and transmit the translation result to the display for the user to view. In addition, the rear camera 9 can also be used as a camera for daily photo and video recording. Users can choose to use the rear camera 9, camera module 2 or scanning unit according to actual usage needs to improve the efficiency of the learning device.

[0071] Furthermore, in some embodiments, Figure 1 As shown, a control key 14 is provided on the scanning body 1. The control key 14 is electrically connected to the rear camera 9. The control key 14 is configured to turn on or off the rear camera 9 in a triggered state.

[0072] Optionally, the control key 14 is a knob switch or a push switch. Figure 1As shown, the rear camera 9 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.

[0073] The control key 14 is electrically connected to the first processor, and the first processor is electrically connected to the rear camera 9. The user triggers the control key 14 to control the rear camera 9 to turn on or off through the first processor, which is very convenient.

[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.
