[0033] The following combination Figure 1-Figure 5 The learning device of the present invention is described.

[0034] like Figure 1 and Figure 2 As shown, the present invention provides a learning device comprising: a grip 1, a device body 2, a camera 3, and a composite key 4. The device body 2 is rotatably mounted on one side of the grip 1 via a rotary drive mechanism and includes a display screen 22. The camera 3 is fixedly mounted on the other side of the grip 1, and the display screen 22 is in communication with the camera 3.

[0035] The composite key 4 includes a control key 41 and a focus knob 42 mounted outside the control key 41. The focus knob 42 is electrically connected to the camera 3 and is used to adjust the focal length of the camera 3. The control key 41 is electrically connected to the rotation drive mechanism and is used to control the rotation of the device body 2 relative to the grip 1.

[0036] The learning device can be a word treasure, listening and speaking treasure, a learning machine, or a repeater. Taking the learning device as an example, the device body 2 can realize various functions of a traditional learning machine, and the camera 3 is installed on the handle 1. The handle 1 for human hand is integrated into the device body 2, and the camera 3 for shooting is added, which enriches the functions of the learning device and improves the integration of the device.

[0037] It is understandable that if Figure 1 As shown, the grip 1 is in the shape of an elongated strip and is used for being held by a human hand. A switch 11 is provided on the side of the grip 1, and the user can turn the learning device on or off by triggering the switch 11.

[0038] The camera 3 is mounted on the back of the grip 1 and is positioned near the top of the grip 1. The camera 3 has a good field of view and can be used to record or photograph text to be translated or questions to be analyzed, allowing for quick access to information to be processed, thereby improving the translation efficiency of the learning device.

[0039] The grip 1 and the device body 2 can share a power supply or have separate power supplies. In the case where the grip 1 and the device body 2 share a power supply, the power supply can be set in the grip 1 or the device body 2. Similarly, the grip 1 and the device body 2 can share a control panel or have separate control panels. In the case where the grip 1 and the device body 2 share a control panel, the control panel can be set in the grip 1 or the device body 2. Optionally, a control panel is installed in the grip 1, and the camera 3 is electrically connected to the control panel. A display screen 22 is installed on the device body 2, and the control panel is electrically connected to the display screen 22, thereby achieving a communication connection between the camera 3 and the display screen 22. The camera 3 sends the recording or shooting information to the control panel, and the control panel can process the recording or shooting information and transmit the processing results to the display screen 22 for display. Alternatively, the control panel transmits the recording or shooting information and the processing results to the display screen 22 for display, so as to facilitate user comparison and viewing. In addition, the camera 3 can also be used as a camera 3 for daily photo and video recording.

[0040] In some embodiments, the display screen 22 is a touch screen. The touch screen is electrically connected to the camera 3. The user can control the opening or closing of the camera 3 through the touch screen and can input other operating instructions through the touch screen.

[0041] like Figure 1As shown, the device body 2 is rotatably mounted on the front of the holding member 1 via a rotary drive mechanism and is disposed near the top of the holding member 1. Optionally, the rotary drive mechanism includes a driving member and a rotating shaft. The driving member is fixed to the interior of the holding member 1. One end of the rotating shaft is transmission-connected to the driving end of the driving member, and the other end is passed through the housing 21 of the holding member 1 and fixedly connected to the back of the device body 2. The driving member drives the rotating shaft to rotate, and the rotating shaft then drives the device body 2 to rotate relative to the holding member 1. Optionally, the driving member is a servo motor or a stepper motor, etc.

[0042] like Figure 1 As shown, the composite key 4 is located on the back of the grip 1. When the grip 1 is held, the composite key 4 is located below the camera 3, making it easy for the user to operate. The focus knob 42 can be rotated to adjust the focus of the camera 3. For example, turning the focus knob 42 counterclockwise increases the focus of the camera 3; turning the focus knob 42 clockwise decreases the focus of the camera 3.

[0043] The control key 41 is located in the middle of the focusing knob 42. By triggering the control key 41, the rotation of the device body 2 relative to the holding piece 1 can be controlled. For example, the rotation drive mechanism drives the device body 2 to rotate a preset angle once. During use, after the user triggers the control key 41, the drive automatically shuts down each time it drives the device body 2 to rotate the preset angle. The preset angle can be 30°, 40° or 90°, etc. Taking the preset angle of 90° as an example, in the initial state, the length direction of the device body 2 is parallel to the length direction of the holding piece 1; after the user triggers the control key 41, the device body 2 rotates until its length direction is perpendicular to the length direction of the holding piece 1 and then stops automatically. For another example, after the control key 41 is triggered, the rotation drive mechanism drives the device body 2 to rotate. After the control key 41 is triggered again, the rotation drive mechanism stops driving.

[0044] The present utility model provides a learning device, in which a device body 2 can be rotatably mounted on one side of a holding member 1 through a rotary drive mechanism, so that the position of the device body 2 relative to the holding member 1 can be adjusted as needed to adapt to the different usage habits of the user. A camera 3 is fixedly mounted on the other side of the holding member 1 and can be used for shooting and recording. A control key 41 for controlling the operation of the rotary drive mechanism and a focus knob 42 for adjusting the focal length of the camera are integrated together to form a composite key 4, which reduces the space occupied by the keys. Compared with the touch screen control method, manual adjustment is more interesting.

[0045] In some embodiments, the control key 41 is configured to control the device body 2 to switch between a first position and a second position relative to the grip 1 after being triggered. Figure 1 and Figure 2As shown, when the device body 2 is rotated to the first position relative to the holding member 1, the length direction of the device body 2 is consistent with the length direction of the holding member 1. Figure 3 and Figure 4 As shown, when the device body 2 is rotated to the second position relative to the holding member 1, the length direction of the device body 2 is perpendicular to the length direction of the holding member 1.

[0046] By rotatably mounting the device body 2 on the holding member 1 , the device body 2 can be switched between vertical and horizontal orientations to adapt to different usage habits of users, thereby improving the user experience.

[0047] In some application scenarios, the control key 41 controls the device body 2 to rotate by a preset angle each time, and the preset angle is 90 degrees. Figure 1 As shown, the device body 2 is in the first position relative to the grip 1. At this time, the length direction of the device body 2 is parallel to the length direction of the grip 1. The user triggers the control key 41, and the device body 2 rotates 90° to the second position relative to the grip 1. At this time, Figure 3 As shown, the length direction of the device body 2 is perpendicular to the length direction of the grip 1. The user triggers the control key 41 again, and the device body 2 rotates 90° in the opposite direction, returning to the initial state. Thus, the user can control the rotation drive mechanism by triggering the control key 41, thereby switching the device body 2 between the first position and the second position. Of course, the preset angle of each rotation of the device body 2 can also be set to other angles. For example, 45° or 60°, etc. This is not specifically limited in the present invention.

[0048] In some embodiments, as Figure 1 and Figure 2 As shown, the width of the device body 2 is greater than the width of the holding piece 1.

[0049] For example, both sides of the device body 2 along its length direction are exposed to the holding piece 1. Optionally, when the device body 2 is rotated to the first position relative to the holding piece 1, the two sides of the device body 2 along its length direction are symmetrically arranged about the center line of the holding piece 1 along its length direction to ensure the balance of the device body 2 during rotation, as well as the aesthetics of the learning device. Of course, the widths between the two sides of the device body 2 along its length direction and the center line of the holding piece 1 along its length direction may also be different, as long as it can ensure that the device body 2 can rotate smoothly. For another example, only one side of the two sides of the device body 2 along its length direction is exposed to the holding piece 1. By setting the width of the device body 2 to be wider, a larger display screen 22 can be installed on the device body 2 to enhance the user's viewing experience and reduce eye damage to the user.

[0050] When the device body 2 is rotated to the first position relative to the holding member 1 , the top of the device body 2 is higher than the top of the holding member 1 .

[0051] like Figure 1 and Figure 2 As shown, when the length direction of the device body 2 is parallel to the length direction of the grip 1, the top of the device body 2 is higher than the top of the grip 1. When the length direction of the device body 2 is perpendicular to the length direction of the grip 1, as shown in FIG. Figure 3 and Figure 4 As shown, the top of the device body 2 can be slightly lower than the top of the grip 1 or slightly higher than the top of the grip 1. By making the top of the device body 2 exposed above the top surface of the grip 1, the device body 2 is ensured to have a larger size, providing sufficient space for arranging a larger display screen 22, improving the user's viewing experience, and reducing eye damage to the user.

[0052] In some embodiments, as Figure 1 、 Figure 3 and Figure 5 As shown, the grip 1 is provided with a sound outlet 12 and a sound pickup hole 13. A speaker, microphone, and voice module are mounted within the grip 1. The microphone's sound pickup end faces the sound pickup hole 13. The speaker's sound output end faces the sound outlet 12. Both the speaker and microphone are electrically connected to the voice module.

[0053] like Figure 1 and Figure 3 As shown, the sound pickup hole 13 is located on the front of the grip 1. The sound outlet 12 can be set at the top or bottom of the grip 1 to ensure the aesthetics of the learning device. The sound output end of the speaker faces the sound outlet 12 to ensure that the speaker has good playback quality. Among them, the microphone is used to pick up the user's voice, for example, to record the voice to be translated or voice operation instructions through the microphone.

[0054] The microphone and the speaker are electrically connected to the voice module respectively. When the microphone receives the voice to be translated, the voice information to be translated is sent to the voice module. The voice module can translate the voice information to be translated and feed back the translation result to the speaker for playback to assist users in learning.

[0055] Specifically, in some embodiments, a voice key 14 is installed on the holding member 1, and the voice key 14 is electrically connected to the control panel.

[0056] like Figure 1 and Figure 3As shown, the voice button 14 is mounted on the front of the grip 1. The voice button 14 is a ring-shaped button. The sound pickup hole 13 is provided on the inner ring of the voice button 14 to facilitate user operation. The voice button 14 is configured to turn the microphone on or off when triggered. During use, the user triggers the voice button 14, and the control panel controls the microphone to turn on to record the voice to be translated or the voice operation instruction to the voice module. The user triggers the voice button 14 again, and the control panel controls the microphone to turn off.

[0057] In a specific embodiment, Figure 5 As shown, the sound outlet 12 is located at the top of the holding member 1.

[0058] In some embodiments, as Figure 2 and Figure 4 As shown, the learning device further includes an operation key 15. The operation key 15 is electrically connected to the camera 3, and the operation key 15 is configured to turn on or off the camera 3 in a trigger state.

[0059] It is understood that the camera 3 and the operating keys 15 are both located on the back of the grip 1 to facilitate user operation. Furthermore, the operating keys 15 are positioned on the back of the grip 1 to ensure the overall aesthetics of the learning device. When the user holds the grip 1, the operating keys 15 are positioned below the camera 3. Of course, the operating keys 15 can also be positioned on the front or side of the grip 1. This is not specifically limited in the present invention.

[0060] The operation key 15 is electrically connected to the control panel, and the control panel is electrically connected to the camera 3. When the user triggers the operation key 15, the control panel controls the camera 3 to turn on or off after receiving the instruction of the operation key 15.

[0061] In some embodiments, a boss 16 is provided on the front of the grip 1 , and the device body 2 is rotatably mounted on the boss 16 , with the back of the device body 2 being in contact with the front of the grip 1 .

[0062] Specifically, the front side of the grip 1, near the top, is recessed inward, forming a concave area. A boss 16 projects from the concave area, with the end face of the boss 16 flush with the outer edge of the concave area. The rotary drive mechanism's shaft passes through the boss 16 and is fixedly connected to the back of the device body 2. The boss 16 shields the shaft and allows the back of the device body 2 to rotate against the front of the grip, ensuring stability during rotation.

[0063] In some embodiments, a scanning head is mounted on one end of the holding member 1. The scanning head can move along the surface of the scanning medium to perform scanning.

[0064] Specifically, the scanning head is installed at the bottom of the holding member 1, that is, at the end of the holding member 1 away from the device body 2. Optionally, the scanning head and the holding member 1 can be connected as one piece, or the scanning head can be detachably arranged at the bottom of the holding member 1. A scanning window is provided at the end of the scanning head, and the scanning window is used to frame the content to be scanned during scanning. The learning device scans the surface of the scanning medium through the scanning head to obtain scanning information. During scanning, the person holds the holding member 1 in his hand and moves along the surface of the scanning medium, and the scanning head scans the content to be scanned.

[0065] The scanning head is electrically connected to the control board. The scanning head transmits scanned information to the control board. The control board can translate the scanned information and transmit the translation results to the display screen 22 for display. Alternatively, the control board transmits both the scanned information and the translated information to the display screen 22 for easy comparison and viewing by the user. This allows the user to conveniently select either the camera 3 or the scanning head for word capture based on actual needs. When the user chooses to scan with the scanning head, the camera 3 can be turned off by triggering the operation key 15, thereby reducing the power consumption of the learning device.

[0066] In some embodiments, as Figure 1 and Figure 3 As shown, the device body 2 includes a housing 21, a display screen 22 and a front camera 5. The front camera 5 and the display screen 22 are both installed in the housing 21.

[0067] Specifically, the rotating shaft of the rotary drive mechanism is fixedly connected to the back of the housing 21. The display screen 22 is mounted in the central area of ​​the front of the housing 21. The front camera 5 is mounted on the front of the housing 21, above the display screen 22. The front camera 5 is used to record or capture images. In addition, when the content to be translated is a long text, the front camera 5 can be used to record or capture the text to be translated to quickly obtain the information to be translated, thereby improving the translation efficiency of the learning device.

[0068] The device body 2 and the handle 1 can share a processing circuit or set up processing circuits separately. For example, a control panel is set only in the handle 1 to simplify the structure of the device body 2, so that the device body 2 with the display screen 22 can be made thinner. For another example, a processor is installed in the device body 2, so that the device body 2 and the handle 1 are respectively provided with processing circuits. The control panel and the processor can be connected to each other by means of wires or Bluetooth modules. The processor is electrically connected to the display screen 22 and the front camera 5 respectively. The front camera 5 can send the input single-question information to be parsed or the text information to be translated to the processor, and the processor can process and analyze the single-question information to be parsed or the text information to be translated, and transmit the processing results to the display screen 22 for display, which is extremely convenient. Optionally, the processor can also send the collected information of the front camera 5 to the control panel for processing and analysis.

[0069] Similarly, the device body 2 and the grip 1 can share a power supply or have separate power supplies. In the case where the device body 2 and the grip 1 share a power supply, the power supply can be set in either the device body 2 or the grip 1. For example, a first power supply is installed in the grip 1, and a second power supply is installed in the device body 2. By respectively setting power supplies in the device body 2 and the grip 1, the standby time of the learning device is extended. The first power supply is electrically connected to the control board, the camera 3 and the scanning head, respectively, to supply power to the control board, the camera 3 and the scanning head at the same time. The second power supply is electrically connected to the processor, the front camera 5 and the display screen 22, to supply power to the processor, the front camera 5 and the display screen 22 at the same time.

[0070] Optionally, the first power source is a rechargeable battery, and the grip 1 is provided with a charging interface, which is electrically connected to the rechargeable battery so as to be charged by connecting to an external power source via the charging interface. Optionally, the second power source is a rechargeable battery, and the first power source and the second power source can be charged via the same charging interface or can be provided with separate charging interfaces.

[0071] In the case where the display screen 22 is a touch screen, the user can also start the question search application of the learning device by touching the touch screen, and complete the entry of the single question to be analyzed through the front camera 5.

[0072] 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.
