[0036] The following is combined Figures 1-12 This invention describes the learning device.

[0037] like Figure 1 As shown, this utility model provides a learning device, including: a device body 1 and a scanning component 2. A storage slot 11 is provided on the back of the device body 1, and a flip cover 13 is rotatably mounted on the opening of the storage slot 11. The scanning component 2 is fixedly mounted on the flip cover 13. When the flip cover 13 is closed on the storage slot 11, the scanning component 2 is housed within the storage slot 11. When the flip cover 13 is flipped open to open the storage slot 11, the scanning component 2 extends out of the storage slot 11, with the scanning end of the scanning component 2 facing the end of the device body 1 that has a trigger element.

[0038] Learning devices can be word generators, listening and speaking devices, learning machines, or repeaters, etc. Taking a learning machine as an example, the device body 1 can realize the various functions of a traditional learning machine. The scanning component 2 is integrated into the device body 1, enabling the learning machine to have scanning capabilities and improving the integration of the device. The scanning component 2 inputs scanned content into the device body 1, and the device body 1 can perform targeted translation, word formation, radical search, synonym / antonym search, pinyin search, sentence formation, or single-question analysis on the scanned content according to the user's instructions, thereby enriching the functionality of the learning device and improving its ease of use.

[0039] Specifically, such as Figure 1As shown, the storage slot 11 is located on the back of the device body 1, near the trigger element. The flip cover 13 is rectangular. The side of the flip cover 13 along its length is parallel to the width direction of the device body 1. Optionally, the side of the flip cover 13 along its length is hinged to the opening of the storage slot 11. The scanning component 2 is fixed to the inside of the flip cover 13, or the scanning component 2 and the flip cover 13 are an integral structure.

[0040] like Figure 1 As shown, when scanning is required, the flip cover 13 is opened, and the scanning component 2 is exposed in the storage slot 11 along with the flip cover 13. The scanning component 2 includes a camera 22 and a fill light. The camera 22 is used to scan while the device body 1 slides on the scanning medium. The content scanned by the camera 22 is recognized by OCR and provides scanning data input to the device body 1. The fill light is used to illuminate the camera 22 to ensure that the camera 22 obtains clear word images.

[0041] like Figure 2 As shown, a display screen 12 is mounted on the front of the device body 1. The display screen 12 is communicatively connected to the camera 22. Specifically, a controller is installed inside the device body 1. The camera 22 is electrically connected to the controller, and the controller is electrically connected to the display screen 12. The camera 22 sends scanning information to the controller. The controller can process the scanning information and transmit the processing result to the display screen 12 for display. Alternatively, the controller can transmit both the scanning information and the processing result to the display screen 12 for easy comparison and viewing by the user.

[0042] like Figure 3 and Figure 4 As shown, after use, the flip cover 13 closes the storage slot 11, sealing the scanning component 2 inside the device body 1, thus providing physical protection for the scanning component 2 and ensuring that it is not easily damaged. When the scanning component 2 is stored, the outer side of the flip cover 13 is flush with the back of the device body 1 to maintain the aesthetic appearance of the entire learning device.

[0043] This utility model provides a learning device. The scanning component 2 can scan while moving on the surface of the scanning medium and display the results with the help of the device body 1, thereby enriching the functions of the learning device. The scanning component 2 is fixedly installed on the flip cover 13, which is rotatably installed in the slot of the storage groove 11. When the scanning component 2 needs to be used, the flip cover 13 is opened, and the scanning component 2 extends out of the storage groove 11 along with the flip cover 13 to open the scanning component 2 for scanning. When the scanning component 2 is finished, the flip cover 13 is closed to the slot of the storage groove 11, and the scanning component 2 is retracted into the inside of the device body 1, so that the scanning component 2 is sealed and stored in the device body 1, thereby forming physical protection for the scanning component 2, ensuring that the scanning component 2 is not easily damaged, and improving the user's convenience.

[0044] Specifically, in some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the learning device also includes a retaining spring 3. A retaining block 131 is provided on the inner side of the flip cover 13. The retaining spring 3 is clamped between the retaining block 131 and the groove wall of the storage slot 11.

[0045] Optionally, the locking block 131 is fixed to the inside of the flip cover 13, or the locking block 131 and the flip cover 13 are an integral structure. A rotating shaft is provided on one side of the flip cover 13. The rotating shaft is rotatably mounted on the wall of the storage groove 11 via a bearing. Alternatively, the rotating shaft is fixed to the wall of the storage groove 11 and rotatably connected to the flip cover 13. A retaining spring 3 is sleeved on the rotating shaft. One end of the retaining spring 3 abuts against the wall of the storage groove 11, and the other end abuts against the locking block 131.

[0046] like Figure 5 As shown, when the scanning component 2 is retracted into the storage slot 11, the locking block 131 compresses the retaining spring 3, and the retaining spring 3 stores energy. Figure 6 As shown, when the scanning component 2 extends out of the storage slot 11, the flip cover 13 is ejected out of the storage slot 11 by the elastic action of the retaining spring 3, and the scanning component 2 is stably supported by the elastic force of the retaining spring 3, ensuring the stability of the scanning component 2 during scanning.

[0047] To ensure that the scanning component 2 does not detach itself when retracted into the device body 1, alternatively, opposite magnetic poles can be provided on the opening of the storage slot 11 and the inner side of the flip cover 13. The attraction between the opposite magnetic poles ensures the stability of the flip cover 13 when it is closed to the opening of the storage slot 11. In this embodiment, a protrusion can be provided on the outer side of the flip cover 13 to facilitate the user's effort to open the flip cover 13.

[0048] In some embodiments, the learning device further includes a push-button latch 4. For example... Figure 5 and Figure 8 As shown, with the flip cover 13 covering the storage slot 11, the push-button latch 4 is in a locked state, housing the scanning component 2 within the storage slot 11. Figure 6 As shown, when the flip cover 13 is flipped open to open the storage slot 11, the push-button latch 4 is in the unlocked state, and the scanning component 2 can extend out from the storage slot 11.

[0049] Optionally, the push-button latch 4 includes a locking part and a latching part. The locking part is fixedly installed on the wall of the storage slot 11, and the latching part is fixed to the inside of the flip cover 13. Figure 5 As shown, when it is necessary to store the scanning component 2, press the flip cover 13 so that the latch engages with the locking part, thereby locking the flip cover 13 to the slot of the storage groove 11 by the press-type latch 4, preventing the scanning component 2 from coming out of the storage groove 11. Figure 6As shown, when the scanning component 2 is needed, press the flip cover 13 again, the latch unlocks and pops out from the locking part, the flip cover 13 pops out of the storage slot 11, and the scanning component 2 extends out of the storage slot 11.

[0050] In some specific embodiments, such as Figure 9 , Figure 10 and Figure 11 As shown, the push-button latch 4 includes a sleeve 41, a positioning pin 42, a lock housing 43, clamping arms 44, and a latch 45. The latch 45 is fixed to the flip cover 13. Both clamping arms 44 are rotatably mounted on the lock housing 43. The lock housing 43 is movably mounted inside the sleeve 41. The positioning pin 42 is fixed to the sleeve 41. The lock housing 43 is provided with a guide groove 431. The sleeve 41 has a limiting part 411.

[0051] With the positioning pin 42 housed in the first position within the guide groove 431, the two clamping arms 44 close and clamp the buckle 45 under the action of the limiting part 411. With the positioning pin 42 housed in the second position within the guide groove 431, the lock housing 43 moves outward relative to the sleeve 41, and the two clamping arms 44 open to release the buckle 45.

[0052] Specifically, the sleeve 41 is fixed to the wall of the storage groove 11. For example... Figure 9 and Figure 10 As shown, the limiting part 411 includes two limiting blocks. The two limiting blocks are symmetrically fixed to opposite sides of the end of the sleeve 41 along its axis. The positioning pin 42 is L-shaped. The positioning pin 42 is fixed to the end of the sleeve 41 and located beside the two limiting blocks. Each limiting block has a limiting groove. The openings of the two limiting grooves are opposite to each other.

[0053] like Figure 9 As shown, the buckle 45 is fixed to the inside of the flip cover 13. Figure 10 As shown, at least a portion of the lock housing 43 passes through the sleeve 41 and is capable of sliding along the inner wall of the sleeve 41. Two clamping arms 44 are respectively hinged to opposite sides of the lock housing 43 along the axis of the sleeve 41. A guide groove 431 is provided on the side of the lock housing 43 facing the positioning pin 42.

[0054] like Figure 10 As shown, when the scanning component 2 needs to be stored, the user presses the flip cover 13, causing the latch 45 to abut against the lock housing 43. Under the pressure of the latch 45, the lock housing 43 moves inward relative to the sleeve 41, simultaneously causing the two clamping arms 44 to slide along the two limiting grooves respectively. Under the limiting action of the limiting part 411, the two clamping arms 44 move closer to each other, locking the latch 45, thereby securely closing the flip cover 13 to the storage groove 11. At this time, the positioning pin 42 and the groove wall of the guide groove 431 at the first position abut against each other to ensure that the two clamping arms 44 can hold the latch 45 tightly and prevent the two clamping arms 44 from sliding out of the limiting part 411.

[0055] like Figure 11 As shown, when the scanning component 2 needs to be used, the user presses the flip cover 13 again. The positioning pin 42 disengages from the first position of the guide groove 431, and the lock housing 43 moves away from the sleeve 41, causing the two clamping arms 44 to slide out from the two limiting grooves respectively. The two clamping arms 44 expand outward to release the buckle 45, thereby unlocking the flip cover 13 and allowing the scanning component 2 to extend out of the storage groove 11 for scanning. At this time, the positioning pin 42 and the groove wall of the guide groove 431 at the second position abut against each other.

[0056] In some embodiments, the guide groove 431 has a first sliding section and a second sliding section connected in sequence. The starting end of the first sliding section and the ending end of the second sliding section are V-shaped. A first position is located at the junction of the starting end of the first sliding section and the ending end of the second sliding section. A second position is located at the junction of the ending end of the first sliding section and the starting end of the second sliding section. The first position is farther from the sleeve 41 than the second position.

[0057] Specifically, the angle between the starting end of the first sliding section and the axis of the sleeve 41 is smaller than the angle between the ending end of the second sliding section and the axis of the sleeve 41. The angle between the starting end of the second sliding section and the axis of the sleeve 41 is larger than the angle between the ending end of the first sliding section and the axis of the sleeve 41.

[0058] Optionally, the first and second sliding segments are curved segments. When the positioning pin 42 is housed in the first position within the guide groove 431, the positioning pin 42 abuts between the beginning of the first sliding segment and the end of the second sliding segment to restrict the movement of the positioning pin 42.

[0059] When the scanning component 2 is needed, pressing the flip cover 13 causes the lock housing 43 to move inward into the sleeve 41. Since the angle between the starting end of the first sliding section and the axis of the sleeve 41 is smaller than the angle between the end of the second sliding section and the axis of the sleeve 41, the positioning pin 42 can slide along the first sliding section to the second position. At this time, the push-button latch 4 is in the unlocked state. When the user presses the flip cover 13 again, the lock housing 43 moves outward from the sleeve 41 under the action of the torsion spring. Since the angle between the starting end of the second sliding section and the axis of the sleeve 41 is larger than the angle between the end of the first sliding section and the axis of the sleeve 41, the positioning pin 42 can slide along the second sliding section to the first position. At this time, the push-button latch 4 is in the locked state.

[0060] Alternatively, such as Figure 12As shown, the first sliding section is divided into a first connecting section 4311, a second connecting section 4312, and a third connecting section 4313 connected in sequence. The second sliding section is divided into a fourth connecting section 4314, a fifth connecting section 4315, and a sixth connecting section 4316 connected in sequence. The first connecting section 4311 and the sixth connecting section 4316 are connected and arranged in a V-shape. The second position is located at the connection between the third connecting section 4313 and the fourth connecting section 4314. The angle between the axes of the first connecting section 4311 and the sleeve 41 is smaller than the angle between the axes of the sixth connecting section 4316 and the sleeve 41. The angle between the axes of the fourth connecting section 4314 and the sleeve 41 is larger than the angle between the axes of the third connecting section 4313 and the sleeve 41.

[0061] When the positioning pin 42 is housed in the first position within the guide groove 431, the positioning pin 42 abuts against the first position between the first connecting section 4311 and the sixth connecting section 4316 to restrict the movement of the positioning pin 42.

[0062] When the scanning component 2 is needed, it is used to continuously press the flip cover 13, the lock case 43 moves into the sleeve 41, and the positioning pin 42 slides along the first connecting section 4311; when the user releases the flip cover 13, the positioning pin 42 transitions from the first connecting section 4311 to the second connecting section 4312, and slides along the second connecting section 4312 and the third connecting section 4313 to the second position. At this time, the push-button latch 4 is in the unlocked state.

[0063] The user presses the flip cover 13 again, and the lock case 43 moves outward from the sleeve 41 under the action of the torsion spring. Since the included angle between the axis of the fourth connecting section and the axis of the sleeve 41 is greater than the included angle between the axis of the third connecting section 4313 and the axis of the sleeve 41, the positioning pin 42 can slide along the fourth connecting section 4314 and the fifth connecting section 4315. When the user releases the flip cover 13, the positioning pin 42 transitions from the fifth connecting section 4315 to the sixth connecting section 4316 and slides along the sixth connecting section 4316 to the first position. At this time, the push-type latch 4 is in the locked state.

[0064] like Figure 9 As shown, the push-button latch 4 also includes an elastic element 46. The elastic element 46 is housed within the sleeve 41 and connected to the lock housing 43. One end of the elastic element 46 is fixed to the wall of the receiving groove 11, and the other end is fixed to the lock housing 43. When the positioning pin 42 abuts against the groove wall of the guide groove 431 at the first position, the elastic element 46 stores force; when the positioning pin 42 disengages from the first position, the force of the elastic element 46 pushes the lock housing 43 outward relative to the sleeve 41, thereby causing the two clamping arms 44 to disengage from the limiting part 411 and expand outward to release the latch 45. Optionally, the elastic element 46 is a spring.

[0065] like Figure 1As shown, a trigger element is provided at one end of the device body 1. The controller is electrically connected to the trigger element, and the controller controls the scanning assembly 2 to start scanning according to the trigger signal from the trigger element.

[0066] In use, the end of the device body 1 contacts the surface of the medium to be scanned. The user presses the learning device, causing the end of the device body 1 to move along the surface of the medium, thus triggering the trigger element under pressure. Upon receiving the trigger signal from the trigger element, the controller controls the camera 22 and the supplementary light in the scanning assembly 2 to turn on. When the user lifts the learning device, the end of the device body 1 separates from the surface of the medium, and the trigger element generates another trigger signal, causing the controller to turn off the camera 22 and the supplementary light. Optionally, the trigger element can be a pressure-sensitive sensor or a mechanical telescopic trigger structure. When the trigger element is a pressure-sensitive element, preferably, it is located at one end of the device body 1 so that the user can hold the device body 1 and press the pressure-sensitive element against the scanning medium to turn on the camera 22. When the trigger element is a mechanical telescopic trigger structure, it includes a telescopic head 5 and a trigger switch. The telescopic head 5 is telescopically mounted on the device body 1. The trigger switch is triggered when the telescopic head 5 retracts into the device body 1. The controller is electrically connected to the trigger switch.

[0067] Specifically, the trigger switch is installed inside the device body 1. The trigger switch is electrically connected to the controller, and the controller is electrically connected to the camera 22. One end of the device body 1 has a through hole. The telescopic head 5 is slidably disposed in the through hole. The telescopic head 5 is used to abut against the scanning medium during scanning.

[0068] Optionally, a spring is provided at one end of the telescopic head 5 located inside the device body 1. In use, the flip cover 13 is opened, allowing the scanning component 2 to extend out of the storage slot 11. The user holds the device body 1 and presses the telescopic head 5 against the surface of the scanning medium. The telescopic head 5 retracts into the device body 1 and contacts the trigger switch, generating a trigger signal. After scanning is complete, the user holds the device body 1 and separates the telescopic head 5 from the scanning medium. The telescopic head 5 resets under the action of the spring, and the trigger switch generates a trigger signal again, stopping the camera 22 from scanning. Then, closing the flip cover 13 allows for the storage of the scanning component 2.

[0069] In other embodiments, the triggering element is a pressure-sensitive element. The pressure-sensitive element and the controller are electrically connected. In use, the user holds the device body 1 and presses the end of the device body 1 with the pressure-sensitive element against the sliding medium surface. The controller controls the switch of the scanning assembly 2 based on the pressure value detected by the pressure-sensitive element to start or stop the scanning. Optionally, the pressure-sensitive element is a piezoresistive pressure sensor or a capacitive pressure sensor.

[0070] Specifically, such as Figure 1As shown, the scanning component 2 includes a housing 21 and a camera 22. The housing 21 is fixed to the flip cover 13. The camera 22 is fixed to one side of the housing 21. When the flip cover 13 is flipped open to open the storage slot 11, the housing 21 is positioned on one side of the camera 22 and perpendicular to the back of the device body 1.

[0071] The side of the housing 21 closest to the flip cover 13 can be fixed to the inner side of the flip cover 13 using screws or adhesive fasteners. Alternatively, the housing 21 and the flip cover 13 can be a single integrated structure. The camera 22 is mounted on the side of the housing 21 closest to the trigger element. Figure 1 As shown, when the scanning component 2 extends out of the storage slot 11, the side of the housing 21 on which the camera 22 is mounted is perpendicular to the back of the device body 1, so that when the user holds the device body 1 and slides it on the surface of the scanning medium, the scanning field of view of the camera 22 can face the scanning medium, preventing the device body 1 from blocking the camera 22.
