[0022] This application provides a learning machine; please refer to it. Figure 1 As shown, the learning machine includes a housing 1, a display screen 4, and a speaker 5 located inside the housing 1. The learning machine can also hold a matching analog keyboard card 3. The housing 1 has an opening 11, and the analog keyboard card 3 is detachably mounted on the housing 1 and covers the opening 11. Different analog keyboard cards 3 have different content; for example, one analog keyboard card 3 contains teaching content about numbers, another about characters, and yet another about letters. When the analog keyboard card 3 is mounted on the housing 1, the learning machine can recognize the analog keyboard card 3 and switch to the mode corresponding to the content on the analog keyboard card 3. The display screen 4 can display the video corresponding to the content on the analog keyboard card 3, and the speaker 5 can play the audio corresponding to the content on the analog keyboard card 3. Of course, the user can touch and press the patterns on the analog keyboard card 3 to cause the display screen 4 to play the image related to the pressed pattern, and to cause the speaker 5 to play the audio related to the pressed pattern. For example, the simulated keyboard card 3 installed on the learning machine contains numbers. When the user presses the number 3 on the simulated keyboard card 3, the display screen 4 shows the number 3 along with an image of three chicks hopping around, and the speaker 5 plays the song "Three Chicks Playing". This increases the interactivity between the user and the learning machine, stimulates the user's learning interest, and improves learning efficiency.

[0023] Therefore, the identification device for the simulated keyboard card 3 on the learning machine is very important. Only by accurately identifying the simulated keyboard card 3 inserted into the learning machine can the learning machine accurately switch to the mode corresponding to the inserted simulated keyboard card 3, thus ensuring that the user can use the learning machine for efficient learning.

[0024] Please refer to some embodiments of this application. Figures 2-5As shown, the learning machine also includes a trigger component 2. A slot 12 is provided on one side of the opening 11 in a circumferential direction. The trigger component 2 is located within the slot 12 and along the path of the simulated keyboard card 3 inserted into the housing 1. This ensures that the trigger component 2 is triggered whenever the simulated keyboard card 3 is inserted into the housing 1. Different simulated keyboard cards 3 have different contact methods with the trigger component 2, thus ensuring the accuracy of the simulated keyboard card 3's recognition. Compared to using photoelectric sensing to recognize the simulated keyboard card 3, this embodiment employs a mechanical triggering method, which is more reliable.

[0025] Specifically, in some embodiments of this application, please refer to Figure 5 As shown, the trigger component 2 includes at least one trigger button 21 and a circuit board 22. The trigger button 21 is disposed on the circuit board 22 and is movably disposed within the slot 12, allowing the trigger button 21 to have a triggered position and a non-triggered position. When the simulated keyboard card 3 is located on the housing 1, it abuts against at least one trigger button 21 to drive the trigger button 21 to move. The learning machine includes a control unit, and the circuit board 22 is coupled to the control unit. The control unit can identify the simulated keyboard card 3 based on the number and position of the triggered trigger buttons 21. When the simulated keyboard card 3 is inserted into the slot 12, the simulated keyboard card 3 can apply a downward force to the trigger button 21 under the abutment action of the slot wall of the slot 12, causing the trigger button 21 to move downward from the non-triggered position to the triggered position. The control unit can sense the number and position of the triggered trigger buttons 21 through the circuit board 22, thereby retrieving the mode corresponding to the simulated keyboard card 3 in the system for user learning.

[0026] Please refer to Figure 5 As shown, in some embodiments of this application, the trigger button 21 includes a button shell, a reset member, and a conductive member. The side of the button shell facing the placement area is a guide surface inclined towards the slot 12. When the analog keyboard card 3 is inserted into the slot 12, it can abut against the guide surface and apply a pushing force to the guide surface towards the slot 12. The pushing force is decomposed into a portion of the downward pressure on the guide surface, causing the button shell to move downward. One end of the reset member is connected to the circuit board 22, and the other end is connected to the button shell. When the button shell moves downward, the reset member is compressed, generating a reset elastic force inside. When the analog keyboard card 3 is removed from the shell 1, the button automatically moves upward from the triggered position to the untriggered position under the action of the reset elastic force of the reset member. The conductive member is located on the button shell. When the button shell moves to the triggered position, the conductive member is coupled to the circuit board 22, thereby generating a trigger signal. The circuit board 22 transmits a signal containing the position information of the analog keyboard card 3 to the controller, enabling the controller to sense the number and position of the triggered buttons 21.

[0027] In detail, when the analog keyboard card 3 is inserted into the housing 1, the controller will receive a signal "1" if the trigger button 21 is triggered, and a signal "0" if the trigger button 21 is not triggered. Assuming there are three trigger buttons 21, and the inserted analog keyboard card 3 can contact the middle trigger button 21 but not the two side trigger buttons 21, then the controller will receive code "010". The controller will retrieve the mode corresponding to 010 from the stored database, thereby recognizing the analog keyboard card 3 and switching to the mode that matches the content of the analog keyboard card 3.

[0028] It is understandable that the more trigger buttons 21 there are, the more internally stored modes there are, and the more simulated keyboard cards 3 are included with the learning machine, thus enabling the learning machine to support a wider range of teaching content. The number of trigger buttons 21 can be set according to actual needs, and this application does not impose specific limitations on this.

[0029] Further, please refer to Figure 4 As shown, in some embodiments of this application, the analog keyboard card 3 has a card block 31 at one end, which is accommodated in the slot 12. The edge of the card block 31 is provided with at least one abutting tooth 32, which abuts against at least one trigger button 21. The abutting teeth 32 are different for different analog keyboard cards 3. The difference in abutting teeth 32 here refers to the difference in either the number or the position of the abutting teeth 32. It can be that the position of the abutting teeth 32 is different. Taking three trigger buttons 21 as an example, for example, two different analog keyboard cards 3 cause the controller to obtain the code "010" and "001", or the number of abutting teeth 32 is different. For example, two different analog keyboard cards 3 cause the controller to obtain the code "001" and "011", or both the position and the number of abutting teeth 32 are different. For example, two different analog keyboard cards 3 cause the controller to obtain the code "001" and "110".

[0030] Therefore, in some embodiments of this application, please refer to Figures 1-5 As shown, the abutting teeth 32 abut against each trigger button 21 in a one-to-one correspondence. On different analog keyboard cards 3, at least one of the number or position of the abutting teeth 32 differs. Taking the trigger component 2 as an example with three trigger buttons 21, there would be seven different combinations, corresponding to seven different analog keyboard cards 3. Alternatively, in some embodiments of this application, the abutting teeth 32 abut against multiple adjacent trigger buttons 21. On different analog keyboard cards 3, at least one of the number of trigger buttons 21 abutting against the abutting teeth 32 and the position of the abutting teeth 32 differs. This allows the controller to obtain codes "110", "011", and "111", which can correspond to three different analog keyboard cards 3. The number and shape of the abutting teeth 32 can be selected according to actual needs.

[0031] It should be noted that the code received by the controller in this embodiment does not contain "000" because the code "000" represents that none of the trigger buttons 21 have been triggered. This is the same as the state where the simulated keyboard card 3 is not inserted into the housing 1. Therefore, the controller cannot determine whether the simulated keyboard card 3 is inserted into the housing 1.

[0032] Please refer to some embodiments of this application. Figure 1 , Figure 4 As shown, the casing 1 has a slot on its periphery, through which the simulated keyboard card 3 is inserted. The slot 12 is positioned opposite the slot. Since the slot 12 is located to the side of the opening 11, rather than at the opening 11 itself, it will not come into contact with the trigger component 2 during the insertion of the simulated keyboard card 3 into the casing 1, thus preventing false triggering. Similarly, positioning the slot 12 opposite the slot ensures that the trigger component 2 is triggered before the simulated keyboard card 3 is fully inserted, preventing it from being triggered during insertion and ensuring the accuracy of trigger component 2's activation.

[0033] Specifically, in some embodiments of this application, the periphery of the housing 1 is provided with an insertion port, through which the simulated keyboard card 3 is inserted, and the slot 12 is disposed opposite to the insertion port. The insertion port can be located on the left, right, front, or rear side of the housing 1. If the length of the insertion port is greater than the length of the opening 11, then the portion of the insertion port extending beyond the sides of the opening 11 forms a slide rail, and the edges of the simulated keyboard card 3 slide through the slide rail to limit the sliding of the simulated keyboard card 3, enabling it to slide accurately into the mating position. In other embodiments of this application, the size of the simulated keyboard card 3 matches the opening 11, allowing the simulated keyboard card 3 to be installed or removed through the opening 11. During installation, simply align the card block 31 with the slot 12, insert it, and then release the simulated keyboard card 3. At this time, the simulated keyboard card 3 can directly enter the opening 11, thus achieving the installation of the simulated keyboard card 3. To ensure that the analog keyboard card 3 does not move within the opening 11, in some embodiments of this application, a limiting plate 13 extends circumferentially towards the interior of the housing 1 from the opening 11. The slot 12 is located on one side of the limiting plate 13, and the circumferential edge of the analog keyboard card 3 abuts against the limiting plate 13. The limiting plate 13 can restrict the position of the analog keyboard card 3 within the opening 11. Together with the card block 31 and the slot 12, it can ensure that the analog keyboard card 3 will not shift within the opening 11.

[0034] 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.
