Description

Card-based learning device

Technical Field

The present disclosure relates to the technical field of educational equipment, and in particular to a plug-in card learning device.

Background Art

With the development of science and technology, various interactive learning devices for children's education have emerged. Common learning devices include: tablet learning devices, smart speaker learning devices, card-insertion learning devices, etc. Among them, card-insertion learning devices will set a detection switch in the middle of the bottom of the card slot to determine whether the card is inserted or not, and start to recognize the card when the detection switch is triggered. When the card is inserted at an angle or not inserted in place, the detection switch is easily triggered by mistake, which leads to problems such as recognition errors or unrecognized content, which in turn causes a high rate of product repairs and returns.

To solve this problem, one current approach is to deepen the card slot so that the card can be positioned by the card slot itself, but this greatly limits the appearance design of the learning device. How to provide a card-insertion learning device that can prevent misidentification and has no limit on the depth of the card slot is a technical problem that needs to be solved in this field.

The present disclosure provides a card-insertion learning device, which is mainly used in the field of early childhood education. In a specific implementation, children can insert various learning cards printed with Chinese characters, pinyin or English words into the learning device, and the learning device can recognize the information of the card, and then find the multimedia file corresponding to the card from the storage unit, and play the multimedia file, so that the child can understand the knowledge information corresponding to the card. The multimedia file can be in the form of audio, video, picture, etc., which is not limited by the present disclosure.

When inserting a card, the user may not insert it properly or the card may be skewed, and the learning device will directly read the card with the wrong posture, which leads to the problem that the current card-insertion learning device is prone to recognition errors. In order to solve the above problems, the present disclosure provides a new card-insertion learning device, including: a body, a detection unit and a control unit.

The body is provided with a card slot for inserting a card, the card slot is configured to at least partially accommodate the card, the insertion end of the card is provided with an identification code, and the body is provided with a card reader for reading the identification code. The present disclosure does not impose any specific restrictions on the specific depth of the card slot, and the card slot can completely accommodate the card or only partially accommodate the card. It should be noted that the card slot at least needs to be able to cover the position of the identification code on the card, so as to ensure that the card reader can read the identification code normally.

The detection unit includes at least two detection switches arranged on the inner wall of the card slot, and the at least two detection switches are configured to be arranged at intervals in the horizontal direction, and are configured to be triggered simultaneously when the card is inserted in place. Since the at least two detection switches are arranged at intervals in the horizontal direction, simultaneous triggering can only be achieved when the card is inserted in the correct position and is not skewed. It is understandable that when the card is skewed to one side, the card can only trigger the detection switch on one side, while the detection switch on the other side cannot be triggered.

The control unit is configured to control the card reader to read the identification code in response to the trigger signal. Specifically, the control unit will control the card reader to perform the card reading step only when at least two detection switches are triggered at the same time. At this time, the card posture is correct, so there will be no misidentification due to the skewed card. If the detection switches are not all triggered, it means that the card has not been inserted into place, which may be due to insufficient insertion depth or skewed insertion angle. The control unit will not control the card reader to perform the card reading step; the user needs to adjust the posture of the card until all detection switches are triggered, and the learning device will start reading the card.

When a card is inserted into the card slot, all detection switches can be triggered simultaneously only when the card is not skewed and inserted in place, thus ensuring that the card is in the correct position when the card reader starts reading. The present invention prevents misidentification and improves the user experience by setting at least two detection switches spaced apart horizontally on the inner wall of the card slot, and controlling the card reader to read when all detection switches are triggered at the same time. In addition, the method of preventing misidentification disclosed in the present invention can be applied to card slots of various depths, does not limit the depth of the card slot, and improves the appearance design space of the card-insertion learning device.

For ease of understanding, the specific structure and working principle of the plug-in card learning device of the present disclosure will be described in detail below with reference to FIG. 1 to FIG. 8 and in combination with embodiments.

With reference to FIGS. 1 to 3 , the plug-in card learning device provided by the present disclosure includes: a body 10, a detection unit and a control unit. As shown in FIGS. 1 and 2 , a card slot 11 for inserting a card 20 is provided on the body 10, and the card slot 11 is configured to at least partially accommodate the card 20. A gear switch 16 may be provided on the body 10, and the gear switch 16 is used to control the power on or off of the plug-in card learning device, and can be used to control the system language setting of the device, thereby providing a bilingual learning function. When the user turns on the gear switch 16, the learning device can read the card 20 inserted in the card slot 11. As shown in FIG. 3 , an identification code 21 is provided at the insertion end of the card 20, and a card reader for reading the identification code 21 is provided in the body 10. It should be noted that the card slot 11 at least needs to be able to cover the position of the identification code 21 on the card 20, so as to ensure that the card reader can read the identification code 21 normally.

The present disclosure does not impose any specific restrictions on the specific depth of the card slot 11. The card slot 11 can fully accommodate the card 20, or only partially accommodate the card 20. In the case where the card slot 11 is deep, since the card slot 11 has a shape that matches the card 20, the card slot 11 can naturally limit the card 20, and the card 20 inserted by the user will basically not be skewed, but the content on the card 20 will basically be covered by the device, which makes the user experience poor. In the case where the card slot 11 is shallow, the user is likely to insert the card incorrectly or skew when inserting the card, and the learning device will directly read the card 20 with the wrong posture, which is prone to recognition errors.

In order to solve the above problems, the present invention is provided with a detection unit that can indirectly detect the position and posture of the card 20, and the card 20 is read only when the position and posture are correct. Specifically, the detection unit includes at least two detection switches arranged on the inner wall of the card slot 11, and the at least two detection switches are constructed to be arranged at intervals in the horizontal direction, and are constructed to be triggered simultaneously when the card 20 is inserted into place. Since at least two detection switches are arranged at intervals in the horizontal direction, simultaneous triggering can only be achieved when the card 20 is inserted in the correct position and is not skewed. It can be understood that when the card is skewed to one side, the card 20 can only trigger the detection switch on one side, while the detection switch on the other side cannot be triggered.

In one embodiment of the present disclosure, referring to FIG. 4 and FIG. 7 , two detection switches are provided, and the two detection switches are configured to be located on opposite sides of the extending direction of the card slot 11, and are configured to cooperate with the two corners of the insertion end of the card 20, respectively. Referring to the viewing direction of FIG. 4 , the two detection switches are located on the left and right sides of the card slot 11, respectively. It can be understood that when the card 20 is correctly inserted into place, the two detection switches will cooperate with the lower left corner and the lower right corner of the card 20, respectively, so as to trigger the two detection switches at the same time. When the card 20 is inserted crookedly, the card 20 can only trigger one of the detection switches, or both detection switches cannot be triggered.

In a specific embodiment of the present disclosure, referring to FIG5 , the detection switch is a touch switch 12, which is directly triggered by pressure or thrust, and can be a button switch, a rocker switch, a micro switch, and other types, and the present disclosure does not limit this. Two touch switches 12 can be installed on the left and right positions of the inner wall of the card slot 11, respectively. When the card 20 is inserted into place, the two touch switches 12 are configured to be triggered by the push of the two corners of the insertion end of the card 20, respectively. When the card 20 is correctly inserted into place, the touch switch 12 on the left side will be pushed and triggered by the lower left corner of the card 20, and at the same time, the touch switch 12 on the right side will be pushed and triggered by the lower right corner of the card 20. Therefore, when the two touch switches 12 are triggered together, it means that the insertion posture of the card 20 is correct.

In another specific embodiment of the present disclosure, the detection switch is an in-place sensor, which can identify whether the card 20 has reached the specified position and is triggered when the card 20 is identified. The in-place sensor can be various types such as an infrared sensor, a photoelectric sensor, a magnetic sensor, etc., and the present disclosure does not limit this. Two in-place sensors can be installed on the left and right positions of the inner wall of the card slot 11, respectively. When the card 20 is inserted into place, the two in-place sensors are configured to be triggered when the two corners of the insertion end of the card 20 are identified, respectively. When the card 20 is correctly inserted into place, the in-place sensor on the left side will identify the lower left corner of the card 20 and be triggered. At the same time, the in-place sensor on the right side will identify the lower right corner of the card 20 and be triggered. Therefore, when the two in-place sensors are triggered together, it means that the insertion posture of the card 20 is correct.

Two specific forms of detection switches are provided above. The detection switches may also be other structures capable of realizing the detection function, and the present disclosure does not limit this. In addition, only two detection switches are provided in the above embodiments. In practical applications, three, four or more detection switches may also be provided. Multiple detection switches are provided on the same horizontal line, thereby ensuring that the card 20 is inserted in the correct position. The detection principle is no different from the case of providing two detection switches, and will not be described in detail. The following description will be given by taking the provision of two detection switches as an example.

The control unit is configured to control the card reader to read the identification code in response to the trigger signal. Specifically, only when at least two detection switches are triggered at the same time, the control unit will control the card reader to perform the card reading step. At this time, the posture of the card 20 is correct, so there will be no wrong recognition due to the skew of the card 20. In the case where the detection switches are not all triggered, it means that the card 20 has not been inserted into place, which may be due to insufficient insertion depth or skewed insertion angle. The control unit will not control the card reader to perform the card reading step; the user needs to adjust the posture of the card 20 until all detection switches are triggered, and the learning device will start reading the card.

When the card 20 is inserted into the card slot, all the detection switches can be triggered simultaneously only when the card 20 is not skewed and inserted in place, thus ensuring that the position of the card 20 is correct when the card reader starts reading. The present invention prevents misidentification and improves the user experience by setting at least two detection switches spaced apart in the horizontal direction on the inner wall of the card slot 11, and controlling the card reader to read when all the detection switches are triggered at the same time. In addition, the method of preventing misidentification disclosed in the present invention can be applied to card slots 11 of various depths, without limiting the depth of the card slot 11, thereby improving the appearance design space of the plug-in learning device.

In one embodiment of the present disclosure, referring to FIG. 4 and FIG. 8 , the card reading device is a plurality of infrared card readers 13. When the card 20 is inserted into place, the plurality of infrared card readers 13 are configured to emit infrared light for identifying the information of the identification code 21 to the card 20 under the control of the control unit. Specifically, as shown in FIG. 8 , the control unit includes a first main board 171, and the plurality of infrared card readers 13 and the two touch switches 12 can be arranged on the first main board 171. When the card 20 is inserted into place, the two touch switches 12 are triggered at the same time, and the first main board 171 controls the infrared card reader 13 to emit infrared light to the card 20 in response to the trigger signal, so as to obtain the information carried by the identification code 21. The plurality of infrared card readers 13 can be arranged at intervals on the first main board 171, so as to evenly correspond to the identification code 21 area on the card 20, thereby ensuring the accuracy of the identification.

In one embodiment of the present disclosure, referring to FIG. 7 and FIG. 8 , the card-inserting learning device further includes a front shell 111 and a rear shell 112 disposed in the body 10, and the front shell 111 and the rear shell 112 enclose a card slot 11. It is understandable that the inner wall of the card slot 11 described above is actually the inner side surface of the front shell 111 and the rear shell 112. As shown in FIG. 8 , a plurality of hollow portions 113 are arranged at intervals in the horizontal direction on the front shell 111 and/or the rear shell 112, and the infrared card reader 13 is configured to emit infrared light to the card 20 through the hollow portions 113.

Taking the hollow portion 113 disposed on the rear shell 112 as an example, as shown in FIG8 , the first main board 171 is disposed at the rear of the rear shell 112, and the two touch switches 12 mounted on the first main board 171 can respectively penetrate the two hollow portions 113 on the left and right sides of the rear shell 112, thereby entering the interior of the card slot 11 and being located at the positions on the opposite sides of the inner wall of the card slot 11. Multiple infrared card readers 13 can correspond to multiple hollow portions 113 one by one, and are controlled by the first main board 171 to emit infrared light to the card 20 located in the card slot 11, thereby obtaining the information carried by the identification code 21. Multiple hollow portions 113 can be arranged at intervals on the rear shell 112, so as to evenly correspond to the identification code 21 area on the card 20, thereby ensuring the accuracy of identification.

The hollow portion 113 may also be disposed on the front shell 111, or disposed on both the front shell 111 and the rear shell 112. When the hollow portion 113 is disposed on the front shell 111, the first main board 171 and the two touch switches 12 and the plurality of infrared card readers 13 mounted thereon are all disposed in front of the front shell 111. When the hollow portion 113 is disposed on both the front shell 111 and the rear shell 112, a main board may be disposed in front of the front shell 111 and in the rear of the rear shell 112, respectively, and the plurality of infrared card readers 13 and the touch switches 12 may be disposed on the two main boards, respectively.

Furthermore, based on the different ways of setting the hollow portion 113, the identification code 21 on the card 20 can also be designed in different ways. Specifically, when the hollow portion 113 is set on the back shell 112, the identification code 21 is set on the back of the card 20; when the hollow portion 113 is set on the front shell 111, the identification code 21 is set on the front of the card 20; when the hollow portion 113 is set on the front shell 111 and the back shell 112, the identification code 21 is set on the front and back sides of the card 20. Setting the identification code 21 on the front or back of the card 20 alone can make the content of the card 20 drawn on the other side more complete; and setting the identification code 21 on both the front and back sides of the card 20 can eliminate the situation where the card 20 cannot be recognized due to the reverse insertion, thereby improving the user experience.

In one embodiment of the present disclosure, the plug-in learning device further includes a speaker unit, as shown in FIG6 , the speaker unit includes a speaker 14 and a speaker switch 15. The control unit is configured to control the speaker 14 to play the audio corresponding to the identification code 21 in response to the sound signal of the speaker switch 15. Specifically, as shown in FIG4 , the control unit may include a second main board 172, and the second main board 172 may be connected to the first main board 171 via a connecting line 173, thereby realizing coordinated control.

Both the gear switch 16 and the speaker switch 15 can be installed on the second main board 172. When the gear switch 16 is in the power-on position, the second main board 172 transmits the power-on signal to the first main board 171 through the connecting line 173, and the first main board 171 can obtain the information of the identification code 21 on the card 20 inserted into the card slot 11 through the touch switch 12 and the infrared card reader 13 installed thereon; when the speaker switch 15 is triggered, the second main board 172 can directly control the speaker 14 to play the audio corresponding to the identification code 21 in response to the sound signal of the speaker switch 15, or the second main board 172 can transmit the sound signal to the first main board 171 through the connecting line 173, and the first main board 171 can control the speaker 14 to play the audio corresponding to the identification code 21.

1 and 4, the plug-in learning device further includes an upper cover 18 and a bottom shell 19, wherein the upper cover 18 is provided with a plurality of densely arranged speaker holes 181, and the setting area of the speaker holes 181 corresponds to the position of the speaker 14 in the body 10, so that the audio played by the speaker 14 can be clearly heard by the user. A battery box 191 is provided on the bottom shell 19, as shown in FIG4, the battery box 191 can be provided in the lower area of the second mainboard 172, and the battery in the battery box 191 can power the entire learning device.

In one embodiment of the present disclosure, the card-insertion learning device further includes a prompt unit, which can send a prompt signal, thereby making the user aware that the device cannot recognize the currently inserted card 20, and the user needs to adjust the posture of the card 20 or reinsert the card 20 in order for the device to read the card normally. The prompt unit in this embodiment is a voice prompt emitted by a speaker. In other embodiments, the prompt unit can also be a picture or text prompt on a display screen, or it can be a prompt signal light that emits light, etc. The present disclosure does not limit the specific method of the prompt. The provision of the prompt unit enables the user to be prompted to adjust the card 20 in a timely manner when the learning device cannot recognize the card 20, thereby improving the user experience.

When at least two detection switches are partially triggered, the control unit is configured to control the prompt unit to send a prompt signal, and/or, when the card reader cannot read the identification code 21, the control unit is configured to control the prompt unit to send a prompt signal. Specifically, only when all the detection switches are triggered, the control unit will control the card reader to read, and when only some of the detection switches are triggered, it means that the card 20 is skewed and cannot be read, so the prompt unit will send a prompt signal to remind the user to adjust the position of the card 20.

When the user inserts the card 20 backwards, the card reader cannot read any identification code 21 because the identification code 21 may be set only on one side of the card 20. When the user inserts the card 20 upside down, the card reader cannot read any identification code 21 because the identification code 21 is only set on the insertion end of the card 20. In both cases, although the card 20 is in the correct position and triggers all detection switches, the card reader cannot read the identification code 21, so the prompt unit will send a prompt signal to remind the user to reinsert the card 20.

In one embodiment of the present disclosure, referring to FIG. 4 and FIG. 5 , a stopper 114 is provided on the inner wall of the card slot 11, and the stopper 114 is configured to be located at a position not higher than the detection switch. When the card 20 is inserted into place, the insertion end of the card 20 is configured to contact and cooperate with the stopper 114. A plurality of stoppers 114 may be arranged at intervals in the horizontal direction, and the upper surface of the stopper 114 is kept horizontal, thereby playing the role of supporting the card 20.

The card 20 inserted into the card slot 11 is inserted to the bottom when it contacts the stopper 114. If the stopper 114 is set at a position higher than the detection switch, the card 20 will not be able to trigger the detection switch. The stopper 114 is constructed to be located at a position not higher than the detection switch so that the card 20 can trigger the detection switch during the insertion process, so that the control unit controls the card reader to read the identification code 21 in response to the trigger signal. Preferably, the position of the stopper 114 is flush with the detection switch, or slightly lower than the detection switch. If the stopper 114 is too much lower than the detection switch, the card 20 will not move into place when the detection switch sends a trigger signal, which may cause the card reader to be unable to read the identification code 21 in time, thereby causing the prompt unit to falsely alarm.

The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the marketplace, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
