[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0040] Please refer to Figure 1-11 , a thinking point - reading learning machine with replaceable learning cards, including a housing 1. A main control chip is provided on the housing 1. A card placement area 2 is formed on the housing 1. A learning card 3 is removably placed on the card placement area 2. An identification area 301 and a pressing area 302 are provided on the learning card 3. An identification unit 4 and a pressing trigger module 5 electrically connected to the main control chip are provided on the housing 1. The pressing trigger module 5 corresponds to the pressing area 302 of the learning card placed on the card placement area 2, and the identification unit 4 corresponds to the identification area 301 of the learning card placed on the card placement area 2. The main control chip can read the identity information carried on the identification area 301 of the learning card through the identification unit 4.

[0041] An elastic pressing member 6 corresponding to the card placement area 2 is further provided on the housing 1. The elastic pressing member 6 forms elastic pressing on the learning card 3 placed on the card placement area 2. By elastically pressing the learning card 3 through the elastic pressing member 6, the problem of "the insertion gap is too small due to pressing the card by the front shell, resulting in easy wear and curling of the part of the card pressed by the front cover" in the traditional method can be effectively avoided.

[0042] In some embodiments, a card slot 201 is formed on the card placement area 2, and the card slot 201 has a pressing opening 202 corresponding to the pressing area 302 of the learning card.

[0043] Preferably, the card slot 201 has a lateral insertion and extraction opening 203 for inserting and extracting the learning card.

[0044] Preferably, a card insertion and extraction guiding groove 204 corresponding to the lateral insertion and extraction opening 203 is further formed on the card slot 201.

[0045] In some embodiments, an identification code is provided on the identification area 301, and the identification unit 4 is a light reflection type identification unit.

[0046] The light reflection type identification unit includes at least one group of identification components, and the identification components include a photosensitive component and a light emitting component welded on a circuit board.

[0047] A grating member 7 is installed on the housing 1, and the grating member 7 has a light guiding hole 701 corresponding to the identification component. When the learning card 3 is inserted into the card slot 201, the light guiding hole 701 of the grating member forms a light guiding channel connecting the identification component and the identification area 301 of the learning card.

[0048] Preferably, a positioning bracket 702 for positioning the photosensitive component and / or the light emitting component is provided in the light guiding hole 701 of the grating member.

[0049] More preferably, the elastic pressing member 6 is configured to elastically press the learning card 3 in the direction of covering the light guiding hole 701. The elastic pressing member 6 presses the learning card 3 tightly on the grating member 7, effectively preventing external light interference during pressing and making the identification more accurate.

[0050] More preferably, a micro switch 8 for detecting that the learning card 3 is inserted in place is provided on the housing 1. The micro switch 8 is configured to apply to the learning card 3 a elastic force opposite to the elastic force applied by the elastic pressing member 6 to the learning card 3; and the elastic force applied by the micro switch 8 to the learning card 3 is less than the elastic force applied by the elastic pressing member 6 to the learning card 3. The micro switch 8 can be used to detect whether the learning card 3 is inserted in place, and can be used to control the turning on of the light emitting component after confirming that the learning card 3 is inserted in place, making the overall energy consumption lower. And through the bidirectional pressing of the elastic pressing member 6 and the micro switch 8, the learning card 3 is more stable after being inserted.

[0051] In some embodiments, the elastic pressing member 6 is a spring piece integrally connected to the grating member 7.

[0052] A learning information storage module 9, a learning information output module 10 and a power module electrically connected to the main control chip are further provided on the housing 1.

[0053] like Figure 1 , 5 As shown, the housing includes a bottom housing 101, a middle housing 102 and a front housing 103. The middle housing 102 is mounted on the bottom housing 101 so that a portion of the bottom housing 101 is exposed outside the middle housing 102. The front housing 103 is mounted on the middle housing 102 so that a portion of the front housing 103 is mounted on the bottom housing 101 and exposed outside the middle housing 102. Thus, a first installation cavity formed by the bottom housing 101 and the middle housing 102, a second installation cavity formed by the middle housing 102 and the front housing 103, and a third installation cavity formed by the front housing 103 and the bottom housing 101 are formed in the housing. The first installation cavity, the second installation cavity and the third installation cavity constitute the installation cavity of the housing 1.

[0054] The card slot 201 is formed by the middle shell 102 and the surface shell 103 , and the click opening 202 is correspondingly arranged on the surface shell 103 .

[0055] The top side of the middle shell 102 is formed as the bottom side wall of the card slot 201, and the click trigger module 5 includes a carbon film click switch 501 attached to the top side of the middle shell 102. The carbon film click switch is a click platform attached to the surface of the corresponding shell to form a corresponding click area. The carbon film click switch includes an upper carbon film and a lower carbon film that are glued to each other, wherein an upper conductive carbon paddle circuit is printed on the upper carbon film, and a lower conductive carbon paddle circuit corresponding to the upper conductive carbon paddle circuit is printed on the lower carbon film. The carbon film click switch can set the circuit in the form of a key matrix.

[0056] After the improvement, there is no need to add an external touch chip to assist in processing. Touch control can be achieved directly through the I / O port of the main control chip. When the corresponding button is pressed, the upper and lower layers of the carbon film click switch 501 will be short-circuited together. The I / O of the main control chip detects the change in the corresponding voltage to calculate the corresponding function pressed and output the corresponding voice. When clicking, the carbon film click switch attached to the surface of the shell is not easily blocked by the shell and the learning card and cannot be pressed smoothly. The sensitivity and reliability of the click trigger are better.

[0057] Preferably, an anti-accidental touch isolation point is provided between the upper carbon film and the lower carbon film to prevent the upper and lower circuits from contacting and conducting when no pressing is performed. The anti-accidental touch isolation point can be provided in the shape of a bracket, which is used to ensure that a gap can be formed between the upper carbon film and the lower carbon film, and when pressing, the key position corresponding to the upper carbon film can be forced to pass downward through the upper and lower through-areas on the bracket and contact the lower carbon film. After canceling the pressing, the gap formed by the bracket enables the upper carbon film to move upward and return to its position. In other embodiments, the anti-accidental touch isolation point can also be provided in a block shape or a dot matrix shape.

[0058] like Figure 9 As shown, the learning information output module 10 includes a speaker 1001, which can output learning information in the form of sound.

[0059] Taking the output of learning information by voice as an example: After inserting the learning card 3, using the principle of optical coupling, the identification code information (such as barcodes) on the learning card 3 is read through photosensitive components and light-emitting components, and at the same time, the data is transmitted to the main control chip for processing; after the main control chip obtains the identity information of the learning card 3, it calls the corresponding learning information from the learning information storage module 9, so that when the user presses the corresponding position on the pressing area 302 of the learning card and triggers the pressing position of the carbon film pressing switch 501, the corresponding voice can be output through the speaker 1001.

[0060] Such as Figure 5 、 9 As shown in the figure, the learning information output module 10 may further include a light-emitting module 1002, which can output learning information by emitting light. In some embodiments, the user can be given a pressing indication by the light or the correctness of the user's pressing can be feedback by the light.

[0061] In some embodiments, the light-emitting module 1002 includes two RGB light combinations, which are respectively arranged on both sides of the front shell 103. It can be used to design various color light prompts for the raising and answering of learning questions, which is more conducive to enhancing the learning fun. A light guide member 1003 is also provided on the front shell 103, and the light is diffused on the surface through the light guide member 1003.

[0062] In some embodiments, in addition to supplying power, the power module also has a power switch. By turning on the learning machine through the power switch, inserting the learning card can perform the pressing operation, and the output information can be output through the learning information output module.

[0063] In some embodiments, the power module includes a rechargeable battery, which is more convenient to use.

[0064] In some embodiments, the learning information storage module 9 includes a memory card 901 that can be electrically connected to the main control chip through a gold finger, and a card slot 902 corresponding to the memory card is provided on the housing 1. By adding a card slot interface for inserting and removing the memory card, when adding content cards later, customers do not need to send the machine back to the manufacturer for upgrading. They can update the card content by converting it into data. Customers only need to buy a new set of content cards, and then they can learn deeper knowledge. This solves the problem that a large-capacity chip needs to be equipped in the machine at the time of factory, which will increase the cost and also increase the expenditure of consumers.

[0065] In some embodiments, a main board 11 is installed inside the housing 1. The photosensitive component and the light-emitting component are soldered on the top side of the main board 11, and the bottom side of the main board 11 has connection terminals corresponding to the carbon film gold fingers of the carbon film pressing switch 501.

[0066] After the carbon film gold finger of the carbon film push-button switch 501 contacts the connection terminal of the main board 11 up and down, it is clamped by the grating member 7 and the middle case 102. The clamping method can be: with the middle case 102 remaining stationary, the grating member 7 is screwed down onto the middle case or the bottom case 101 through screws, so that the grating member 7 has a downward movement, thereby pressing the main board 11 and the carbon film gold finger downward onto the middle case 102, making the contact between the connection terminal of the main board and the carbon film gold finger stable, and effectively ensuring the position of the light guide hole 701 at the same time, making the light guide effect provided by the grating member 7 during the identification code recognition process more stable.

[0067] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
