[0036] The following combination Figures 1 to 4 The present invention describes a learning device provided by the present invention.

[0037] This embodiment provides a learning device, such as Figure 1 As shown, it includes: a device body 10, a scanning component 20 and an elastic member 30. The device body 10 includes a housing 11 and a control board disposed in the housing 11, and the scanning component 20 includes a scanning head 21 and a camera disposed on the scanning head 21, and the camera is connected to the control board for communication. Figure 2 As shown, the housing 11 has a housing cavity 12, and the housing cavity 12 has an opening 121 located on the side wall of the housing 11. The non-scanning end of the scanning head 21 is connected to the side wall of the housing cavity 12 away from the opening 121 through the elastic member 30. Figure 3 and Figure 4 As shown, a limiter 22 is provided on one side of the scanning head 21, and a clamping member 13 is provided on the housing 11. When the scanning assembly 20 is in the storage state, as shown in FIG. Figure 2 As shown, the clamping member 13 cooperates with the limiting member 22, and the scanning assembly 20 is accommodated in the accommodating cavity 12. When the scanning assembly 20 is in the scanning state, as shown in FIG. Figure 3 As shown, the clamping member 13 is separated from the limiting member 22 , and the scanning assembly 20 is partially extended out of the opening 121 under the action of the elastic member 30 .

[0038] The learning device is a portable device such as Tingshuobao, a repeater, an electronic dictionary, a learning machine, etc. The device body 10 is used to realize the basic functions of Tingshuobao, a repeater, an electronic dictionary, a learning machine, etc.

[0039] like Figure 3As shown, the scanning head 21 has a scanning window. When the scanning assembly 20 is in a scanning state, the scanning window is exposed to the housing 11 so as to frame the content to be scanned on the scanning medium. Optionally, the camera is a monocular camera, a binocular camera or a CCD sensor.

[0040] A display screen 50 is installed on the front of the housing. The content scanned by the scanning component 20 is transmitted to the control board, which is processed by the control board in the device body 10 to obtain the pinyin, interpretation, part of speech, synonyms / antonyms, translation, examples, ancient poems and other contents of the scanned content, and display them on the display screen 50. Among them, the control board is connected to the camera through a wire, and the cavity wall of the accommodating cavity 12 is provided with a wire hole, and the wire is passed through the wire hole. The wire between the control board and the camera has a sufficient length to ensure that the scanning component 20 remains electrically connected to the control board after popping out of the accommodating cavity 12. Optionally, the wire hole is located on the cavity wall of the accommodating cavity 12 opposite to the opening 121, or on the cavity wall consistent with the pop-up direction. The scanning head 21 is provided with a protective sleeve, the length of the protective sleeve is not less than the moving stroke of the scanning component 20, and the wire is passed through the protective sleeve. The protective sleeve is inserted into the wire hole and can slide back and forth along the axial direction of the wire hole. Since the protective sleeve has a certain hardness, the protective sleeve can be used to prevent the stretched wire from gathering on the cavity wall of the accommodating cavity 12 opposite to the opening 121 when the scanning assembly 20 moves back and forth.

[0041] One end of the housing 11 has a receiving cavity 12 with an opening 121. Figure 2 As shown, opening 121 is located on the top wall of housing 11, and accordingly, scanning assembly 20 pops out from the top of housing 11. It is understood that opening 121 may also be located on the left, right, or bottom wall of housing 11. An elastic member 30 is disposed on the side of the accommodating chamber 12 opposite opening 121. Under the action of elastic member 30, scanning assembly 20 can pop out of opening 121 to the exterior of housing 11. Optionally, elastic member 30 is a spring, and the wall of accommodating chamber 12 is provided with an accommodating groove 16. The spring is partially received within accommodating groove 16, which limits the position of the spring and provides guidance for its expansion and contraction.

[0042] A limiter 22 is provided on one side of the scanning head 21, and a corresponding clamping member 13 is provided on the side wall of the housing 11. Specifically, the clamping member 13 is a blocking bar provided on the inner wall of the housing 11, and its extending direction is perpendicular to the ejection direction of the scanning assembly 20. Figure 2When the user does not need to use the scanning function, the scanning component 20 is pushed into the accommodating cavity 12, and the clamping member 13 cooperates with the limiting member 22 to constrain the scanning component 20 in the accommodating cavity 12. At this time, the elastic member 30 accumulates force. It should be noted that the scanning component 20 is accommodated in the accommodating cavity 12 means that the end of the scanning component 20 is flush with the side wall of the shell 11, or the end face of the scanning component 20 is lower than the side wall of the shell 11, thereby protecting the scanning head 21 from collision and damage, while also maintaining the overall beauty of the learning device, making it easy to carry, and effectively protecting the camera to prevent dust from falling on its surface.

[0043] refer to Figure 3 When the user desires to use the scanning function, the engagement between the stopper 22 and the latch 13 is released, and the force securing the scanning assembly 20 within the accommodating cavity 12 disappears. Subsequently, under the action of the elastic member 30, the scanning assembly 20 extends into the opening 121. It will be appreciated that the scanning function of the scanning assembly 20 can be triggered by either a pressure sensor provided on the scanning head 21 or a start button provided on the device body. This invention does not specifically limit the method for triggering the scanning function of the scanning assembly 20.

[0044] In the learning device provided by the embodiment of the present invention, the scanning component 20 is accommodated in the accommodating cavity 12 with the cooperation of the limiting member 22 and the snap-connector 13. After the limiting member 22 and the snap-connector 13 are separated, the elastic member 30 pops the scanning component 20 out of the accommodating cavity 12. While integrating the scanning function on the device body 10, the scanning component 20 is ejected and stored, which is convenient for protecting the camera when the scanning component 20 is not in use and reducing the size of the learning device, providing users with a good usage experience.

[0045] like Figure 3 and Figure 4 As shown, the scanning head 21 has a stopper 23 . When the scanning assembly 20 is in a scanning state, the stopper 23 abuts against the inner side of the side wall of the housing 11 where the opening 121 is provided.

[0046] After the elastic member 30 ejects the scanning assembly 20 from the accommodating cavity 12, the abutting force between the stopper 23 and the inner wall of the housing 11, as well as the elastic force of the elastic member 30, constrains the scanning assembly 20's freedom of movement in the ejection direction, thereby improving the stability of the scanning assembly 20 during scanning. Furthermore, the abutment of the stopper 23 against the inner side of the sidewall of the housing 11 defining the opening 121 further limits the extension of the scanning assembly 20, preventing the entire scanning assembly 20 from being ejected from the opening 121.

[0047] In one specific embodiment, the stopper 23 is provided independently of the limiter 22. For example, a stopper 23 is provided on the scanning head 21, closer to the scanning end of the scanning assembly 20 than the limiter 22. The stopper 23 may be disposed circumferentially around the scanning head 21 or simply to the side of the scanning head 21. The present invention does not specifically limit the arrangement of the stopper. In another specific embodiment, the stopper 23 and the limiter 22 are integrally formed, with the stopper 23 being the end surface of the limiter 22 facing the opening 121.

[0048] refer to Figure 2 In this embodiment, the stopper 22 includes a cantilever 24 and a first stopper 241 protruding from one side of the cantilever 24. The first end of the cantilever 24 is connected to the sidewall of the scanning head 21, and a gap is formed between the second end of the cantilever 24 and the sidewall of the scanning head 21. When the scanning assembly 20 is in the stored state, the clamping member 13 abuts against the first stopper 241, preventing the scanning assembly 20 from escaping from the accommodating cavity 12 and ensuring that the scanning assembly 20 is stably fixed within the accommodating cavity 12.

[0049] like Figures 2 to 4 As shown, the learning device also includes an unlocking member 40, which can be press-fitted into the housing 11. One end of the unlocking member 40 located within the housing 11 faces the cantilever 24. Under the pressure of the unlocking member 40, the cantilever 24 is pushed toward the scanning head 21, elastically deforming the cantilever 24 and separating the first stop 241 from the engaging member 13. Under the action of the elastic member 30, the scanning assembly 20 extends from the opening 121 until the stop 23 abuts against the inner side of the sidewall of the housing 11 providing the opening 121, partially exposing the scanning assembly 20 from the housing 11 and switching to the scanning state. As the elastic component slides into the accommodating cavity 12, the first limiting portion 241 abuts against the side of the clamping member 13 facing the opening 121, and the clamping member 13 pushes the cantilever 24 toward the scanning head 21, driving the first limiting portion 241 to bypass the clamping member 13. Then, under the rebound force of the cantilever 24, the cantilever 24 drives the first limiting portion 241 away from the scanning head 21, and the first limiting portion 241 abuts against the side of the clamping member 13 facing away from the opening 121.

[0050] Alternatively, the stopper 22 can be an elastic clamp, and the engaging member 13 can be a latching hole provided in the wall of the accommodating chamber 12. When the scanning assembly 20 is stored, the elastic clamping head is locked in the latching hole, preventing the scanning assembly 20 from being ejected. When scanning is required, the scanning assembly 20 is pushed, causing the elastic clamping head to disengage from the latching hole, and the elastic member 30 pushes the scanning assembly 20 out of the accommodating chamber 12.

[0051] In the learning device provided by the embodiment of the present invention, the setting of the cantilever 24 can drive the first limiting portion 241 to abut against the side of the clamping member 13 away from the opening 121 or separate from the clamping member 13 under the action of the unlocking member 40, making the storage and extension of the scanning component 20 easier and faster.

[0052] Optional, such as Figures 2 to 4 As shown, the cantilever 24 is further provided with a second limiting portion 242 , which is spaced apart from the first limiting portion 241 in the extending direction of the cantilever 24 . Compared to the first limiting portion 241 , the second limiting portion 242 is closer to the opening 121 .

[0053] When the scanning component 20 moves into the accommodating chamber 12, the first limiting portion 241 first contacts the clamping member 13. If the scanning component 20 continues to be pushed, the clamping member 13 and the second limiting portion 242 are abutted against each other, thereby limiting the movement of the scanning component 20 into the accommodating chamber 12 with the help of the second limiting portion 242, thereby preventing the elastic member 30 from being damaged too quickly due to excessive force.

[0054] In one embodiment, a first inclined surface is provided at the end of the clip 13. Under the action of an external force, the scanning assembly 20 moves toward the side of the accommodating chamber 12 away from the opening 121. As the scanning assembly 20 enters and exits the accommodating chamber 12, the first inclined surface abuts against the end surface of the first limiting portion 241 to provide guidance, thereby ensuring the smoothness of the storage and extension of the scanning assembly 20. Specifically, the clip 13 is provided with a first inclined surface on the side facing the opening 121 and / or on the side facing away from the opening 121. The first inclined surface of the clip 13 provided on the side facing the opening 121 provides guidance for the scanning assembly 20 to slide into the accommodating chamber 12; the first inclined surface of the clip 13 provided on the side facing away from the opening 121 provides guidance for the scanning assembly 20 to pop out of the accommodating chamber 12.

[0055] In another embodiment, a second inclined surface is provided at the end of the first limiting portion 241. When the scanning component 20 moves in and out of the accommodating chamber 12 under the action of an external force, the second inclined surface abuts against the end of the clamping member 13 to provide guidance as the scanning component 20 moves, which can also ensure the smoothness of the storage and extension of the scanning component 20. Specifically, the first limiting portion 241 is provided with a second inclined surface on the side facing the opening 121 and / or on the side facing away from the opening 121. The second inclined surface of the first limiting portion 241 provided on the side facing the opening 121 provides guidance for the scanning component 20 to pop out of the accommodating chamber 12; the second inclined surface of the first limiting portion 241 provided on the side facing away from the opening 121 provides guidance for the scanning component 20 to slide into the accommodating chamber 12.

[0056] In another embodiment, a first inclined surface is provided at the end of the clamping member 13 , and a second inclined surface is provided at the end of the first limiting portion 241 , to ensure smoothness in the storage and extension of the scanning assembly 20 .

[0057] The shell 11 is provided with a mounting hole 17, and the mounting hole 17 corresponds to the limit member 22 in the storage state. The unlocking member 40 includes a pin and a rebound member, and the pin can be slidably inserted into the mounting hole 17. One end of the pin is exposed to the shell 11 for pressing, the other end of the pin is connected to the first end of the rebound member, and the second end of the rebound member is connected to the inner wall of the shell 11. Optionally, the rebound member is a spring, and the spring is sleeved with the pin or installed next to the pin. When the pin is pressed, the rebound member extends and accumulates force, and the end of the pin located in the shell 11 pushes the limit member 22, driving the limit member 22 to separate from the clamping member 13. After the pressing force disappears, the rebound member drives the pin to move outside the shell 11 to achieve reset. In addition, the unlocking member 40 can also be a pin, and correspondingly, the shell 11 is provided with a socket, and the socket corresponds to the position of the first limit part 241 in the storage state. After the pin is inserted into the socket, pushing the limit member 22 can also achieve unlocking.

[0058] Specifically, under the action of the pressing force, the unlocking member 40 moves along the axis of the mounting hole 17 toward the stopper 22, pushing the stopper 22 toward the scanning head 21, causing the stopper 22 to separate from the engaging member 13. Under the action of the elastic member 30, the scanning assembly 20 extends from the opening 121. After unlocking, the pin moves in the opposite direction along the axis of the mounting hole 17 under the action of the resilient member, away from the stopper 22, preparing for the next unlocking. In this embodiment, by pressing the pin, the user can easily control the extension of the scanning assembly 20, making the use of the learning device more flexible and convenient.

[0059] Furthermore, if Figure 2 As shown, the wall of the accommodating cavity 12 is provided with a slide rail 14 . As the scanning assembly 20 pops out or slides in, the scanning head 21 slides along the slide rail 14 , thereby ensuring the stability and accuracy of the scanning assembly 20 sliding in and out of the accommodating cavity 12 .

[0060] Specifically, in one embodiment, the cross section of the slide rail 14 is U-shaped or dovetail-shaped, such as Figure 4 As shown, the scanning head 21 is provided with a protruding slider 25, which is slidably mounted on the slide rail 14. As the scanning assembly 20 is ejected and slid in, the slider 25 moves along the slide rail 14 to provide guidance. Optionally, two slide rails 14 are provided on the wall of the accommodating chamber 12, forming a slide groove 15 between the two slide rails 14. The scanning assembly 20 is slidably embedded in the slide groove 15, and the scanning head 21 slides under the guidance of the slide groove 15, thereby ensuring the accurate and stable movement trajectory of the scanning head 21.

[0061] In the learning device provided in this embodiment, Figure 1 As shown, the housing 11 further includes a front shell 18 and a cover plate 19 . The front shell 18 is provided with a slot body, and the cover plate 19 is covered on the slot body to form the accommodating cavity 12 .

[0062] 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.
