[0030] The following is combined Figures 1-8 This invention describes the learning device.

[0031] like Figure 1 and Figure 2 As shown, this utility model provides a learning device, including: The scanning body 1 includes a grip 11 and a scanning head disposed at one end of the grip 11. A finger support 111 is protruding from the back of the grip 11.

[0032] The main body of the device 2 is installed on the front of the grip 11.

[0033] The rear camera 3 is fixedly mounted on the back of the grip 11.

[0034] The camera switch 4 is mounted on the grip 11 and electrically connected to the rear camera 3. The finger rest 111 provides tactile positioning for the camera switch 4.

[0035] Learning devices can be vocabulary learning tools, listening and speaking learning tools, learning machines, or repeaters, etc. Taking a learning machine as an example, the main body 2 of the device can realize various functions of a traditional learning machine, and the scanning body 1 is integrated into the main body 2 of the device, enabling the learning machine to have a scanning function and improving the integration of the device.

[0036] like Figure 1 As shown, the bottom of the holder 11 is the scanning end of the scanning body 1. Optionally, the scanning head is detachably disposed at the bottom of the holder 11, or the scanning head and the holder 11 can be integrally connected. The end of the scanning head is provided with a scanning window 12, which is used to select 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.

[0037] like Figure 1 As shown, the grip 11 is elongated and designed for hand gripping. During scanning, the user holds the grip 11 and moves it along the surface of the scanning medium while the scanning head scans the content to be scanned. A power switch 14 is located on the side of the grip 11, allowing the user to turn the learning device on or off by triggering the power switch 14.

[0038] like Figure 1 As shown, the rear camera 3 is fixed to the back of the grip 11 and positioned near the top of the grip 11 to prevent the user's hand from obstructing the camera when holding the device.

[0039] The rear camera 3 has a wide field of view. When scanning lengthy texts to be translated or single questions to be analyzed, users can quickly record or photograph the text or questions using the rear camera 3 to improve the word-capturing efficiency of the learning device. In addition, the rear camera 3 can also be used as a camera for everyday photos and videos.

[0040] like Figure 1As shown, the finger rest 111 protrudes from the back of the grip 11. The finger rest 111 and the back of the grip 11 can be integrally connected or fixedly installed on the back of the grip 11. The finger rest 111 is used to provide tactile positioning for the camera switch 4. Optionally, when the user holds the learning device, one scenario in which the finger rest 111 provides tactile positioning for the camera switch 4 is: the user's middle finger rests on the finger rest 111, at which time the index finger can be placed directly on the camera switch 4, facilitating the user's quick reaction to capture the scene. The positions of the finger rest 111 and the camera switch 4 can also be designed based on other operating habits. For example, when the user's ring finger rests on the finger rest 111, the middle finger or index finger can be placed directly on the camera switch 4.

[0041] Optionally, the finger rest 111 protrudes from the central area of ​​the back of the grip 11, i.e., located in the user's hand area, allowing the user to easily perceive the specific location of the camera switch 4 by touch. This enables the rear camera 3 to be quickly turned on or off without visual inspection, improving the ease of use of the learning device. The camera switch 4 can be designed to be relatively large; for example, its width can occupy 2 / 5 to 2 / 3 of the width of the grip 11, and it should be adapted to the grip 11 to facilitate operation of the camera switch 4 while holding the learning device.

[0042] The main body 2 of the device is fixedly or rotatably mounted on the front of the grip 11. For example, the main body 2 of the device is fixed to the grip 11. Figure 1 and Figure 2 As shown, the length direction of the main body 2 is consistent with the length direction of the gripping member 11. Figure 3 and Figure 4 As shown, the length direction of the device body 2 is perpendicular to the length direction of the grip 11. Alternatively, the device body 2 can be rotatably mounted on the grip 11, allowing the position of the device body 2 relative to the grip 11 to change, thereby adapting to different user habits and improving the user experience of the learning device. Specifically, as... 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 holding member 11. By rotating the device body 2, the length direction of the device body 2 becomes perpendicular to the length direction of the holding member 11, as shown. Figure 3 and Figure 4 As shown, this enables the display screen 22 to switch between portrait and landscape modes, improving the user experience.

[0043] The scanning body 1 and the device body 2 can share a power supply or have separate power supplies. If they share a power supply, the power supply can be located within either the scanning body 1 or the device body 2. Similarly, the scanning body 1 and the device body 2 can share a control board or have separate control boards. If they share a control board, the control board can be located within either the scanning body 1 or the device body 2. Optionally, a control board 5 is installed within the grip 11. The camera switch 4 is electrically connected to the control board 5, and the control board 5 is electrically connected to the rear camera 3. The camera switch 4 is configured to turn the rear camera 3 on or off when triggered. This allows the user to conveniently select either the rear camera 3 or the scanning head for word extraction based on actual needs. When the user chooses to use the scanning head, the rear camera 3 can be turned off by triggering the camera switch 4, reducing the power consumption of the learning device.

[0044] like Figure 2 As shown, a display screen 22 is mounted on the main body 2 of the device. The control board 5 is electrically connected to the display screen 22, thereby enabling communication between the scanning head and the rear camera 3 and the display screen 22 respectively. The scanning information from the scanning head and / or the shooting information from the rear camera 3 are sent to the control board 5. The control board 5 can process the scanning information from the scanning head and / or the shooting information from the rear camera 3, and transmit the processing results to the display screen 22 for display. Alternatively, the control board 5 can transmit the scanning information from the scanning head and / or the shooting information from the rear camera 3 along with the processing results to the display screen 22 for easy comparison and viewing by the user.

[0045] This utility model provides a learning device. The scanning head can scan the surface of the scanning medium. The rear camera 3 is fixedly installed on the back of the grip 11 for recording or taking pictures of the text to be translated, the questions to be analyzed, or everyday photos. Thus, scanning and photography functions are integrated on the basis of traditional learning devices. A finger rest 111 is protruding on the back of the grip 11, and the camera switch 4 is installed on the finger rest 111 so that the user can easily feel the specific location of the camera switch 4 by touch, making operation convenient. The main body 2 of the device can be rotatably installed on the front of the grip 11, and the position of the main body 2 relative to the grip 11 can be changed to adapt to different user habits and improve the user experience.

[0046] In some embodiments, such as Figure 5 As shown, the finger support 111 includes a supporting portion 1111 and a limiting portion 1112 disposed on the opposite side of the supporting portion 1111. The supporting portion 1111 and the two limiting portions 1112 are connected to form a groove 1110. The camera switch 4 is at least partially installed in the groove 1110.

[0047] Specifically, both the support portion 1111 and the limiting portion 1112 protrude outward from the back of the gripper 11. The support portion 1111 and the limiting portion 1112 can be integrally connected. The size of the groove 1110 is adapted to the camera switch 4. The two limiting portions 1112 are arranged in parallel and are located on opposite sides of the support portion 1111. The camera switch 4 is located inside the groove 1110, and the bottom wall of the camera switch 4 is slidably attached to the support portion 1111. The side walls of the opposite side of the camera switch 4 are slidably attached to the two limiting portions 1112. By installing the camera switch 4 inside the groove 1110 formed by connecting the support portion 1111 and the two limiting portions 1112, in addition to allowing the user to feel the specific location of the finger rest 111, i.e., the camera switch 4, and ensuring that the user can quickly trigger the camera switch 4 without visual observation, the ease of use of the learning device is improved. It also makes the space more compact, with the finger rest 111 and the camera switch 4 designed almost adjacent to each other. Of course, the finger rest 111 and the camera switch 4 can be set at intervals, as long as the finger rest 111 allows for convenient operation of the camera switch 4 without the need for visual observation.

[0048] In some embodiments, camera switch 4 is a rocker switch.

[0049] Specifically, such as Figure 6 and Figure 7 As shown, the rocker switch includes a button cap 41 and a limiting boss 42 disposed on the button cap 41. The button cap 41 is movably mounted on the grip 11, and the limiting boss 42 is located inside the grip 11 to prevent the button cap 41 from falling out of the grip 11. The control board 5 is provided with a resilient actuated switch 51, which is electrically connected to the rear camera 3. When the button cap 41 is pressed, the button cap 41 can press against the resilient actuated switch 51 or move away from the resilient actuated switch 51.

[0050] like Figure 7 As shown, the gripper 11 includes a housing 112 and a rear cover 113. The housing 112 and the rear cover 113 are fixedly connected to form a receiving cavity. The housing 112 may further include a front shell and a rear shell, thereby forming a mounting cavity between the front shell and the rear shell. The control plate 5 is located within the receiving cavity. In some embodiments, the inner wall of the rear cover 113 is provided with a plurality of positioning posts 1131 spaced apart. When installing the control plate 5, the outer edge of the control plate 5 can be sequentially locked onto the plurality of positioning posts 1131 by a plurality of screws 1132.

[0051] In one embodiment, the back cover 113 has a through hole, and a limiting boss 42 is arranged circumferentially around the keycap 41 and protrudes outward from the keycap 41. The keycap 41 extends out of the back cover 113 through the through hole, and the limiting boss 42 is located inside the back cover 113, abutting against the inner wall of the back cover 113 to prevent the keycap 41 from coming out of the through hole. In a specific embodiment, the keycap 41 is fixed with retaining springs at opposite ends along the length of the gripper 11, and the other ends of the two retaining springs are fixedly connected to the back cover 113. By switching between the extended and retracted states of the two retaining springs, the keycap 41 can be rotated relative to the gripper 11. For example, when the keycap 41 is pressed, the first retaining spring is in the retracted state and the second retaining spring is in the extended state. When the keycap 41 is pressed again, the first retaining spring is in the extended state and the second retaining spring is in the retracted state. Of course, in addition to rotation, the keycap 41 can also move linearly or in other forms relative to the gripper 11 to achieve the purpose of pressing the elastically actuated switch 51. Furthermore, the possibility of replacing the elastic actuation switch 51 here with other types of switches cannot be ruled out.

[0052] The outer end face of the button cap 41 is concave, serving as the pressing part 411, which matches the curvature of a human hand's fingers for easy pressing. When the user presses the button cap 41, the elastic actuation switch 51 is triggered. In the triggered state, the control board 5 controls the rear camera 3 to turn on. When the user presses the button cap 41 again, causing it to rotate in the opposite direction, the control board 5 controls the rear camera 3 to turn off based on the trigger signal from the elastic actuation switch 51.

[0053] In some embodiments, the device body 2 is rotatably mounted on the grip 11. For example... Figure 1 and Figure 2 As shown, when the device body 2 is rotated to the first position relative to the gripper 11, the length direction of the device body 2 is consistent with the length direction of the gripper 11. Figure 3 and Figure 4 As shown, when the device body 2 is rotated to the second position relative to the gripper 11, the length direction of the device body 2 is perpendicular to the length direction of the gripper 11.

[0054] The main body 2 of the device can be manually rotated and mounted on the grip 11, or it can be automatically rotated by a rotation drive mechanism. It should be noted that the main body 2 and the grip 11 can also rotate and stop at other relative positions, such as when the angle between their length directions is acute. By rotatably mounting the display 2 on the grip 11, the display screen 22 can be switched between portrait and landscape modes to adapt to different user habits, offering high convenience and improving the user experience of the learning device. In some embodiments, such as... Figure 1 and Figure 2As shown, the width of the device body 2 is greater than the width of the grip 11. Setting the width of the device body 2 to be wider allows for a larger display screen 22, improving the user's viewing experience and reducing eye strain.

[0055] The main body 2 has both sides exposed on its length, extending beyond the gripper 11. When the main body 2 rotates relative to the gripper 11 to the first position, the two sides of the main body 2 are symmetrically arranged about the center line of the gripper 11 along its length to ensure the balance of the main body 2 during rotation and the aesthetics of the learning device. Of course, the widths between the two sides of the main body 2 and the center line of the gripper 11 along its length can be different, as long as it ensures smooth rotation of the main body 2. Alternatively, the width of the main body 2 and the width of the gripper 11 can be the same.

[0056] When the device body 2 is rotated to the first position relative to the gripper 11, the top of the device body 2 is higher than the top of the gripper 11.

[0057] 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 gripper 11, the top of the device body 2 is higher than the top of the gripper 11. When the length direction of the device body 2 is perpendicular to the length direction of the gripper 11, as... Figure 3 and Figure 4 As shown, the top of the device body 2 can be slightly lower than or slightly higher than the top of the grip 11. By exposing the top of the device body 2 to the top surface of the grip 11, the device body 2 can be made longer, allowing for a larger display screen, improving the user's viewing experience and reducing eye strain.

[0058] In some embodiments, the device body 2 is rotatably mounted on the gripper 11 via a rotary drive mechanism. For example... Figure 2 and Figure 4 As shown, a control key 13 is mounted on the grip 11. The control key 13 is configured to control the main body 2 of the device to switch from a first position to a second position or from a second position to a first position when triggered.

[0059] Optionally, the rotary drive mechanism includes a drive component and a rotating shaft. The drive component is fixed inside the gripper 11, one end of the rotating shaft is connected to the drive end of the drive component, and the other end extends out of the front housing 112 and is fixedly connected to the back of the device body 2. The drive component drives the rotating shaft to rotate, which in turn drives the device body 2 to rotate relative to the gripper 11. Optionally, the drive component is a servo motor or a stepper motor.

[0060] Control key 13 is electrically connected to the drive unit. The user turns the drive unit on or off by triggering control key 13. Optionally, control key 13 can be a knob or a push button, etc. After the user triggers control key 13, the drive unit automatically turns off after each time it drives the main body 2 of the device to rotate a preset angle.

[0061] In some application scenarios, the preset angle for each rotation of the main body 2 is 90°. For example, as... Figure 1 As shown, the initial position of the device body 2 is the first position. When the user triggers control key 13, the device body 2 rotates 90° clockwise to the second position. At this time, as... Figure 3 As shown, the length direction of the device body 2 is perpendicular to the length direction of the grip 11. When the user triggers the control key 13 again, the device body 2 rotates 90° counterclockwise. At this time, the length direction of the device body 2 is parallel to the length direction of the grip 11. Thus, the user can control the rotation drive mechanism by triggering the control key 13, thereby switching the device body 2 relative to the grip 11 between a first position and a second position.

[0062] In other embodiments, depending on the user's usage habits, the preset angle for each rotation of the device body 2 can be set to other angles, such as 45° or 60°. This invention does not specifically limit this.

[0063] In one specific embodiment, such as Figure 2 and Figure 4 As shown, in the holding state, the control key 13 is located on the front of the grip 11 and below the main body 2 of the device. Optionally, the control key 13 can be located in the central area of ​​the front of the grip 11 for user operation. Of course, the control key 13 can also be located on the side or back of the grip 11, and this utility model does not specifically limit this.

[0064] Specifically, such as Figure 2 As shown, the main body 2 of the device includes a housing 21, a display screen 22, and a front-facing camera 23. Both the front-facing camera 23 and the display screen 22 are mounted on the housing 21.

[0065] The display screen 22 is mounted in the central area of ​​the front of the housing 21. The front-facing camera 23 is mounted on the front of the housing 21, above the display screen 22. The front-facing camera 23 is used to record or capture images. Additionally, when the content to be translated is a lengthy text, the front-facing camera 23 can be used to record or capture the text, thereby improving the translation efficiency of the learning device. Alternatively, the front-facing camera 23 can also be used to input individual questions to be analyzed.

[0066] In some embodiments, a processor is installed within the device body 2. The control board 5 and the processor are connected via a wire or Bluetooth module. The processor is electrically connected to the display screen 22 and the front-facing camera 23. The front-facing camera 23 can send the input question or text to be analyzed to the processor, which can process and analyze the question or text and transmit the processing results to the display screen 22 for user viewing. Optionally, the processor can also send the information collected by the front-facing camera 23 to the control board 5 for processing and analysis. By installing a processor within the device body 2, the scanning body 1 and the device body 2 are each equipped with a processing device, making it convenient to activate only the device body 2 or the scanning body 1. Of course, the scanning body 1 and the device body 2 can also share a processing device.

[0067] Similarly, the scanning body 1 and the device body 2 can share a power supply or have separate power supplies. When the scanning body 1 and the device body 2 share a power supply, the power supply can be located within the scanning body 1 or within the device body 2. For example, a first power supply is installed within the grip 11. A second power supply is installed within the device body 2. The first power supply is electrically connected to the control board 5, the rear camera 3, and the scanning head, respectively, to simultaneously power these components. The second power supply is electrically connected to the processor, the front camera 23, and the display screen 22, to simultaneously power these components. By using two power supplies, the standby time of the learning device is improved.

[0068] Optionally, the display screen 22 is a touchscreen. When the display screen 22 is a touchscreen, the user can input operation commands by tapping the touchscreen, such as launching the question-searching application on the learning device, or turning the front-facing camera 23 on or off. The front-facing camera 23 can be used to input text to be translated or to take photos for everyday use.

[0069] 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.
