[0002] Learning machines are electronic teaching products and are a relatively popular type of portable learning device. Most common learning machines use a punch-card mechanism, which recognizes information on learning cards. Card-based learning machines are particularly suitable for children's self-study. They are simple to operate: simply insert a card into the recognition area, and the card is recognized and the corresponding content is displayed to the user.

[0003] Existing card-based learning machines mostly use a combination of infrared light and barcodes to recognize cards. However, these devices often use an open cavity to house the infrared light sensor, making it easy for debris to fall into the cavity and block the infrared light transmission channel, resulting in card recognition failure or inaccurate recognition results. Furthermore, infrared light from adjacent infrared sensors can easily interfere with each other, further leading to inaccurate recognition results. Utility Model Content

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] Figure 1 and Figure 2 The following is a schematic diagram showing the structure of an embodiment of the plug-in intelligent learning machine of the utility model. Figure 1 It is a schematic diagram of the overall structure. Figure 2 This is a schematic diagram of the decomposition structure. Figure 1 and Figure 2 As shown, the plug-in intelligent learning machine includes: a housing 1, a plurality of infrared tube assemblies 2, a light guide 3, a circuit board 4 and a signal output assembly 5.

[0030] The housing 1 has a card insertion area 11 and a card reading area 12 on its upper surface. The card reading area 12 is provided with a plurality of through-holes 121 arranged in parallel or side by side. A translucent keyboard input assembly 13 is also provided on the surfaces of the card insertion area 11 and the card reading area 12. The keyboard input assembly 13 covers the through-holes 121 and is made of translucent PVC material, which has excellent light transmittance and does not block the propagation of infrared light.

[0031] Multiple infrared tube assemblies 2 are mounted on the housing 1, with each infrared tube assembly 2 facing a through hole 121. The term "infrared tube assembly 2" refers to the combination of an infrared emitting tube and a photosensitive receiving tube, or an infrared receiving tube, or an infrared receiving head. The infrared emitting tube is used to emit infrared light, while the photosensitive receiving tube, infrared receiving tube, or infrared receiving head is used to receive infrared light reflected by the card.

[0032] The light guide 3 is disposed between the infrared tube assembly 2 and the upper surface of the housing 1. It is provided with multiple light guide channels 31. The infrared tube assembly 2 is disposed at the bottom end of the light guide channel 31. The top end of the light guide channel 31 extends through the through hole 121 to a position flush with the upper surface of the housing 1. In this embodiment, each infrared tube assembly 2 corresponds to a light guide channel 31, so that the infrared light emitted or received by each infrared tube assembly 2 can only propagate through its corresponding light guide channel 31, thereby preventing mutual interference.

[0033] The circuit board 4 is disposed in the housing 1 and is electrically connected to the plurality of infrared tube assemblies 2 and the keyboard input assembly 13 respectively.

[0034] The signal output component 5 is disposed on the housing 1 and electrically connected to the circuit board 4 .

[0035] Specifically, the circuit board 4 is used to receive the infrared light information transmitted by the infrared tube assembly 2 to identify the card and output the content corresponding to the card through the signal output assembly 5. It should be noted that each card is associated with a barcode, and each barcode corresponds to a corresponding content. By identifying the barcode, the corresponding content can be output through the signal output assembly 5.

[0036] In addition, a keyboard input component 13 is also provided in this embodiment, which can be used in conjunction with the signal output component 5 to enrich the functions of the learning machine, and also prevent foreign objects from falling into the light guide channel 31. The size of the keyboard input component 13 matches the size of the card insertion area 11, so that the keyboard input component 13 covers the surface of the card insertion area 11, and it does not need to find a separate location to set up the keyboard. The position of the card insertion area 11 is usually larger, and can provide enough space to set up more keys. The more keys there are, the more diversified the information that can be input, and the more functions the learning machine can realize, thereby making the learning machine more functional.

[0037] In this embodiment, a light guide 3 is provided between the infrared pair tube assembly 2 and the through hole 121 on the housing 1, so that the infrared light emitted by each infrared pair tube assembly 2 propagates along a specific light guide channel 31 without mutual interference, thereby making the card recognition result more accurate. The translucent keyboard input assembly 13 covering the light guide channel 31 prevents foreign objects from falling in while ensuring that the infrared light can penetrate, thereby preventing inaccurate recognition caused by foreign objects blocking the light guide channel 31.

[0038] Furthermore, the card-insertion type intelligent learning machine also includes a cover plate 6, which covers the upper surface of the shell 1. The cover plate 6 is provided with a card insertion window 61 facing the card insertion area 11 and a baffle plate 62 facing the card reading area 12. The baffle plate 62 and the shell 1 form a accommodating cavity with an open side, and the opening side of the accommodating cavity is adjacent to the card insertion area 11.

[0039] Specifically, the housing 1 is sequentially divided into a functional area 14, a card insertion area 11, and a card reading area 12. The circuit board 4 is disposed in the functional area 14, and the infrared tube assembly 2 is disposed in the card reading area 12. The card insertion window 61 of the cover plate 6 is sized to match the size of the card insertion area 11 and is disposed just around the edge of the card insertion area 11, thereby limiting the position of the inserted card. A baffle 62 is disposed directly opposite the card reading area 12, and the side edges of the baffle 62 just surround the three sides of the card reading area 12 to form a accommodating cavity structure, leaving only one side adjacent to the card insertion area 11 open. This allows one end of a card inserted into the card insertion area 11 to be inserted into the card reading area 12 through this opening, and then infrared light emitted by the infrared tube assembly 2 passes through the light guide channel 31 and the keyboard input assembly 13 to illuminate the barcode of the card for card recognition.

[0040] Further, such as Figure 3 、 Figure 4 and Figure 5 As shown, the infrared tube assembly 2 includes an infrared light emitting assembly 21 and a photosensitive assembly 22. A partition wall 32 is provided in the middle of the light guide channel 31 to form a light output channel 311 and a light input channel 312. The infrared light emitting assembly 21 is provided at the bottom port of the light output channel 311, and the photosensitive assembly 22 is provided at the bottom port of the light input channel 312. The top of the partition wall 32 is lower than the upper surface of the shell 1.

[0041] Specifically, the infrared pair tube assembly 2 includes an infrared light emitting assembly 21 and a photosensitive assembly 22. In order to further reduce the interference of infrared light reflected from the non-barcode area, in this embodiment, the infrared light emitting assembly 21 and the photosensitive assembly 22 are respectively arranged in the light output channel 311 and the light input channel 312. The infrared light emitted by the infrared light emitting assembly 21 propagates in the light output channel 311 and will not directly propagate to the photosensitive assembly 22 of the light input channel 312 due to the obstruction of the partition wall 32. It can only irradiate the barcode area of the card, enter the light channel under the reflection of the barcode area, and be received by the photosensitive assembly 22, thereby reducing interference in the infrared recognition process and improving the accuracy of the recognition result. In addition, in order to ensure that the infrared light reflected by the card can enter the light input channel 312, the top of the partition wall 32 needs to be lower than the upper surface of the shell 1 to provide a channel for the propagation of infrared light.

[0042] For further information, see Figure 3 and Figure 6 The plug-in smart learning machine also includes a light board 23 , on which multiple infrared tube assemblies 2 are arranged. The light board 23 and the circuit board 4 are electrically connected via a flat cable 24 .

[0043] Specifically, multiple infrared tube assemblies 2 are provided to enable recognition of a sufficient number of cards. To facilitate control of the infrared tube assemblies 2, all infrared tube assemblies 2 are mounted on a light board 23, which is electrically connected to the circuit board 4. The light board 23 is located in the card reading area 12, and the circuit board 4 is located in the functional area 14. The card insertion area 11 is provided with a wiring channel (not shown in the figure), and the cable 24 is installed in the wiring channel to achieve electrical connection between the light board 23 and the circuit board 4.

[0044] Further, such as Figure 6 As shown, shock-absorbing foam 25 is provided on the cable 24 .

[0045] Specifically, the shock-absorbing foam 25 is provided on the flat cable 24 to protect the flat cable 24 and reduce the possibility of damage to the flat cable 24 .

[0046] Further, such as Figure 3 As shown, a card sensing component 231 is further provided on the light board 23 , and the card sensing component 231 passes through the housing 1 and extends to the card reading area 12 .

[0047] Specifically, in order to realize the automatic identification process of the card, a card sensing component 231 is set on the light board 23 in this embodiment. The active button of the card sensing component 231 extends through the shell 1 to the card reading area 12. When the card is inserted into the card reading area 12, the card squeezes the active button of the card sensing component 231, and the card sensing component 231 is triggered, sending a trigger signal to the circuit board 4. After receiving the trigger signal, the circuit board 4 controls the infrared tube component 2 to work and identify the identification code on the card.

[0048] Furthermore, in order to enrich the functions of the learning machine, in this embodiment, the signal output component 5 includes a video output component 51 and an audio output component 52 which are electrically connected to the circuit board 4 respectively. The video output component 51 is arranged on the upper surface of the shell 1, and the audio output component 52 is arranged inside the shell 1.

[0049] Specifically, the video output component 51 can output video images to enhance user interactivity. For example, the video output component 51 can be used to play video content related to a card for the user to watch, thereby enriching the user's learning experience. The audio output component 52 is primarily used to play audio information related to the card content, facilitating user learning and memorization.

[0050] Compared with traditional learning machines that can only realize audio output, the plug-in intelligent learning machine with video output component 51 in this embodiment has richer functions, structural keyboard input component 13, can realize more interactive operations, and provides better user experience.

[0051] Further, such as Figure 1 、 Figure 2 and Figure 6 As shown, anti-collision silica gel 15 is provided on the corner of the housing 1 adjacent to the video output component 51.

[0052] Specifically, the video output assembly 51 and the audio output assembly 52 are arranged side by side in the functional area 14. Therefore, one long side and one short side of the video output assembly 51 are adjacent to the edge of the housing 1, the other long side is adjacent to the card insertion area 11, and the other short side is adjacent to the audio output assembly 52. The video output assembly 51 includes a display screen. To prevent the display screen from being damaged, anti-collision silicone 15 is provided near the corners of the video output assembly 51. When the learning machine is dropped, the anti-collision silicone 15 provided at these corners can reduce the impact force on the video output assembly 51, thereby reducing the possibility of damage to the display screen.

[0053] Further, such as Figure 1 、 Figure 2 and Figure 6 As shown, a protective silicone 16 is provided on one side of the longer side of the housing 1 adjacent to the video output component 51 .

[0054] Specifically, to further protect the display screen, this embodiment provides protective silicone 16 on one side of the housing 1 adjacent to the longer side of the video output assembly 51. The longer side of the video output assembly 51 is also susceptible to damage during a collision. By providing protective silicone 16 on the side of the housing 1 parallel to this longer side, the longer side of the video output assembly 51 is protected during a collision. The shorter side of the video output assembly 51 adjacent to the edge of the housing 1, however, is adjacent to the anti-collision silicone 15 and does not require additional protection.

[0055] Further, such as Figure 1 、 Figure 2 As shown, a concave portion 17 is provided on a side of the card insertion area 11 away from the card reading area 12 .

[0056] Specifically, an inner recess 17 is provided on the side of the card insertion area 11 away from the card reading area 12 , thereby facilitating the user to remove the inserted card.

[0057] Further, such as Figure 6 As shown, a battery (not shown in the figure) electrically connected to the circuit board 4 is further provided in the housing 1 , and a charging interface 41 is also provided on the circuit board 4 , which extends through the housing 1 to the outside.

[0058] Specifically, the battery is preferably made of a rechargeable lithium battery, which is used to supply power to the circuit board 4, the signal output component 5, the keyboard input component 13, and the infrared tube component 2. The charging interface 41 is used to charge the battery.

[0059] Although preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic inventive concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Clearly, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
