DETAILED DESCRIPTION

[0035] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the utility model, but the embodiments of the utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the utility model, rather than all of the embodiments.

[0037] Reference Figures 1 to 6 As shown, this embodiment provides a thinking machine, including a front shell 1, a rear shell 2, a middle plate 3, a question card 7, a main board 4 and a negative pressure component 5 electrically connected to the main board 4.

[0038] The front shell 1 is connected to the rear shell 2 and encloses a receiving cavity, and the middle plate 3, the main plate 4 and the negative pressure assembly 5 are all located in the receiving cavity. A mounting notch 11 is provided on the front shell 1 at a position corresponding to the middle plate 3, and the title card 7 is located in the mounting notch 11 and is plugged into the front shell 1.

[0039] An adsorption channel 31 connected to the negative pressure component 5 is provided on the middle plate 3, and the adsorption channel 31 passes through the middle plate 3 in the direction from the front shell 1 to the rear shell 2. The negative pressure component 5 is used to generate negative pressure in the adsorption channel 31 when the main board 4 is powered, so as to adsorb and fit the question card 7 on the middle plate 3.

[0040] In a specific implementation, the thinking machine includes a front shell 1 and a rear shell 2. The front shell 1 is located at the front side of the rear shell 2 and can be connected to and enclosed with the rear shell 2 to form a accommodating cavity, which can be used to accommodate devices such as the middle plate 3, the main board 4 and the negative pressure component 5. The main board 4 is electrically connected to the negative pressure component 5, so that power can be supplied to the negative pressure component 5 through the main board 4, so that the negative pressure component 5 can be started to perform a negative pressure pumping operation.

[0041] Specifically, refer to Figure 5 and Figure 6As shown, a mounting notch 11 is also provided at a position corresponding to the middle plate 3 on the front shell 1, that is, part of the middle plate 3 can be exposed from the mounting notch 11. The title card 7 is installed in the mounting notch 11 and plugged with the front shell 1, so as to fix the title card 7 and prevent the title card 7 from falling off or shifting. Furthermore, the middle plate 3 is also provided with an adsorption channel 31 that penetrates the middle plate 3 along the direction from the front shell 1 to the rear shell 2. The adsorption channel 31 is connected to the negative pressure component 5, so that the negative pressure component 5 can be powered through the main board 4, so that the negative pressure component 5 draws air from the adsorption channel 31, and then forms a negative pressure environment in the adsorption channel 31. Since the title card 7 is located on the side of the middle plate 3 away from the rear shell 2, when the adsorption channel 31 penetrates the middle plate 3, it is equivalent to that the orifice of the adsorption channel 31 is in contact with the title card 7, so that the title card 7 can be reliably attached and adsorbed on the middle plate 3 under the action of negative pressure. Through the fitting and adsorption of the question card 7 and the middle plate 3, not only can the unevenness problem caused by the deformation and warping of the question card 7 be improved, but also the fixing effect of the question card 7 can be further improved to ensure that the thinking machine can be used normally.

[0042] It should be noted that the fitting of the question card 7 and the middle plate 3 means that the question card 7 and the middle plate 3 are completely fitted, that is, there is no gap at any position between the side of the question card 7 close to the middle plate 3 and the side of the middle plate 3 close to the question card 7, thereby effectively improving the deformation and warping of the question card 7 and preventing the question card 7 from moving even when a child pushes it.

[0043] Exemplarily, in this embodiment, the front shell 1 and the rear shell 2 can be fixed by screwing or by clamping. In addition, when the middle plate 3 is located in the accommodating cavity, it can also be fixed to either the front shell 1 or the rear shell 2 by fasteners. In addition, when the air extraction device 51 is located in the accommodating cavity, it can be fixed by fasteners. The air extraction device 51 and the main board 4 can be electrically connected by directly connecting wires or by plugging and connecting connectors.

[0044] The thinking machine provided in this embodiment includes a front shell 1, a rear shell 2, a middle plate 3, a question card 7, a main board 4, and a negative pressure component 5 electrically connected to the main board 4. The front shell 1 is connected to the rear shell 2 and encloses to form a receiving cavity, and the question card 7 is located in the installation notch 11 on the front shell 1 and plugged with the front shell 1. By arranging the negative pressure component 5 in the receiving cavity and arranging the adsorption channel 31 that penetrates and connects the negative pressure component 5 on the middle plate 3, power can be supplied to the negative pressure component 5 through the main board 4, so that the negative pressure component 5 can evacuate air from the adsorption channel 31 to form a negative pressure in the adsorption channel 31, and then the question card 7 can be reliably attached to the middle plate 3 under the action of negative pressure. That is to say, in the thinking machine of the embodiment of the utility model, in addition to being fixed by plugging and matching with the front shell 1, the question card 7 can also be adsorbed and attached to the middle plate 3 by the negative pressure provided by the negative pressure component 5, which can not only improve the unevenness caused by the deformation and warping of the question card 7, but also further improve the fixing effect of the question card 7 to ensure that the thinking machine can be used normally.

[0045] Reference Figure 4 As shown, in some embodiments, the negative pressure component 5 includes an air suction device 51 and a connecting pipe 52.

[0046] The exhaust device 51 can be specifically arranged on the cavity wall of the accommodating cavity or can also be arranged on the side of the middle plate 1 away from the question card 7. One end of the connecting pipe 52 is connected to the exhaust device 51, and the other end of the connecting pipe 52 is connected to the adsorption channel 31.

[0047] During specific use, the exhaust device 51 is electrically connected to the main board 4, so that the main board 4 supplies power to the exhaust device 51, and then the exhaust device 51 generates negative pressure by exhausting air, so that the gas in the exhaust process passes through the connecting pipe 52 and the adsorption channel 31 in sequence and directly reaches the side of the question card 7 facing the middle plate 3 (that is, the back of the question card 7), and then the back of the question card 7 generates negative pressure and is tightly attached to the side of the middle plate 3 away from the rear shell 2 (that is, the outer surface or front surface of the middle plate 3).

[0048] Exemplarily, the air extraction device 51 may be an air pump with an air extraction and adsorption function. For example, the air pump may be any one of an electric diaphragm air pump, an electromagnetic micro air pump, a piezoelectric micro air pump, and a motor micro air pump, and may be selected according to actual needs.

[0049] Exemplarily, the connecting pipe 52 can be a flexible tube such as plastic or silicone, so that the flexible tube can be bent and arranged in the accommodating cavity according to the internal space of the accommodating cavity and the position of the adsorption channel 31, so that the routing of the connecting pipe 52 inside the accommodating cavity is more regular.

[0050] In addition, the connecting pipe 52 can be fixed on the middle plate 3 by adding glue, or can also be fixed on the cavity wall of the accommodating cavity. Alternatively, in other implementations, the connecting pipe 52 can also be fixed on the middle plate 3 or the cavity wall of the accommodating cavity by buckles, etc. When the connecting pipe 52 is fixed on the middle plate 3, the connecting pipe 52 can be specifically fixed on the side of the middle plate 3 away from the question card 7, so as to avoid affecting the fit between the question card 7 and the middle plate 3.

[0051] Reference Figure 4 As shown, in some embodiments, the adsorption channels 31 include a plurality of adsorption channels 31 , and the plurality of adsorption channels 31 are arranged in an array on the middle plate 3 .

[0052] The connecting pipeline 52 includes a connecting main pipeline 521 and multiple connecting branch pipes 522. The connecting main pipeline 521 is connected to the exhaust equipment 51, one end of each connecting branch pipe 522 is connected to the connecting main pipeline 521, and the other end of each connecting branch pipe 522 is connected to each adsorption channel 31 one by one.

[0053] That is to say, by setting up multiple adsorption channels 31, and the connecting branch pipes 522 are also set to be multiple accordingly, it is possible to use a vacuum device 51 to cooperate with a connecting main pipeline 521 to achieve simultaneous vacuuming from multiple adsorption channels 31 through multiple connecting branch pipes 522, thereby forming a negative pressure environment in the multiple adsorption channels 31, so that different positions of the question card 7 can be evenly and reliably attached to the middle plate 3 under the action of the negative pressure generated by the corresponding adsorption channels 31, so as to further improve the fit between the question card 7 and the middle plate 3, so as to effectively improve the unevenness of the lifting card and further improve the fixing effect of the question card 7.

[0054] For example, refer to Figure 1 and Figure 4 As shown, the adsorption channels 31 may include at least two rows (at least two rows are evenly spaced along the width direction of the thinking machine, i.e., along Figure 1 The y1-y2 direction shown is evenly spaced), for example Figure 1 As shown, it can be arranged in three rows, each row can include at least two adsorption channels 31 (evenly spaced along the length direction of the thinking machine, that is, along the Figure 1 The x1-x2 directions shown are evenly spaced), for example Figure 1 As shown, it can be set to three. That is, three rows and three columns of adsorption channels 31 can be formed on one middle plate 3, and the number of adsorption channels 31 is 9 in total. Correspondingly, the number of connecting branch pipes 522 is also 9. At this time, in order to make the adsorption branch pipes be connected to the corresponding adsorption channels 31, the length and position of each adsorption branch pipe can be different.

[0055] In addition, the specific number and arrangement positions of the adsorption channels 31 can be set according to actual needs.

[0056] In addition, if the title card 7 is inserted along the direction of y1-y2 and plugged into the front shell 1, when the title card 7 is adsorbed and fitted with the middle plate 3 under the action of negative pressure, the adsorption and fitting between the title card 7 and the middle plate 3 can be carried out in sequence along the direction of y1-y2.

[0057] Reference Figure 4 As shown, in some embodiments, a micro switch 6 electrically connected to the main board 4 of the thinking machine is provided on the middle board 3. The micro switch 6 can trigger the main board 4 to supply power to the negative pressure component 5 when the question card 7 is plugged into the front shell 1.

[0058] That is to say, when the question card 7 is inserted into place so that the question card 7 and the front shell 1 are plugged together, the question card 7 will trigger the microswitch 6, and then the microswitch 6 will trigger the mainboard 4 to supply power to the negative pressure component 5, thereby automatically triggering the negative pressure component 5 to evacuate air, and then the question card 7 can be adhered to the middle plate 3 under the action of negative pressure to improve the fixing effect. The entire operation process has a high degree of automation and is easy to operate.

[0059] For example, in order to facilitate the arrangement of the micro switch 6, the micro switch 6 can be arranged on the side of the middle plate 3 away from the question card 7, so that the question card 7 squeezes the middle plate 3 after being inserted into place, and then the squeezing force is transmitted to the micro switch 6 through the middle plate 3 to trigger the micro switch 6. Alternatively, when the micro switch 6 is arranged on the side of the middle plate 3 away from the question card 7, an avoidance hole can be provided on the middle plate 3 for the handle of the micro switch 3 to pass through, so that the handle can directly contact the question card 7, so that the micro switch 6 is triggered by the handle after the question card 7 is inserted into place.

[0060] Reference Figure 3 and Figure 4 As shown, in some embodiments, the aperture of the adsorption channel 31 gradually decreases in the direction from the front shell 1 to the rear shell 2.

[0061] Since the side of the middle plate 3 away from the rear shell 2 is the appearance surface of the middle plate 3, that is, the side of the middle plate 3 away from the rear shell 2 after removing the question card 7 can be viewed by the user, in order to ensure the aesthetics of the middle plate 3 to a certain extent and prevent external dust and debris from entering the adsorption channel 31, and in order to ensure that the aperture size of the adsorption channel 31 is suitable to meet the requirements of the exhaust efficiency, the aperture of the adsorption channel 31 can be set to gradually decrease in the direction from the front shell 1 to the rear shell 2, that is, the aperture of the adsorption channel 31 on the side close to the question card 7 has the smallest diameter, and the aperture on the side away from the question card 7 has the largest diameter.

[0062] Alternatively, in other implementations, in order to achieve the above-mentioned effect, it is not necessary to set the aperture of the adsorption channel 31 to gradually decrease in the direction from the front shell 1 to the rear shell 2, and it is only necessary to set the aperture of the adsorption channel 31 on the side close to the question card 7 to be smaller than the aperture of the adsorption channel 31 on the side away from the question card 7.

[0063] In some embodiments, the side of the middle plate 3 close to the title card 7 is a non-smooth surface.

[0064] The middle plate 3 is provided with a convex portion extending toward the direction close to the question card 7, and the convex portion is provided corresponding to the adsorption channel 31. The side of the convex portion away from the middle plate 3 is a smooth surface and contacts and cooperates with the question card 7. The convex portion has a through hole connected to the adsorption channel 31.

[0065] That is to say, when the appearance surface of the middle plate 3 is a non-smooth surface, such as a textured surface, the fitting effect between the middle plate 3 and the title card 7 may be poor. Therefore, a convex portion extending in the direction close to the title card 7 can be provided on the middle plate 3. The side of the convex portion away from the middle plate 3 is in contact with the title card 7 and is a smooth surface. Therefore, the fitting effect between the convex portion and the title card 7 can be improved.

[0066] At the same time, a through hole connected to the adsorption channel is provided on the convex portion, so that when the vacuum device 51 generates negative pressure by vacuuming, the gas can pass through the connecting pipe 52, the adsorption channel 31 and the through hole in sequence and directly reach the side of the question card 7 facing the middle plate 3 (that is, the back of the question card 7), and then the back of the question card 7 generates negative pressure and is tightly attached to the side of the middle plate 3 away from the rear shell 2 (that is, the outer surface or front surface of the middle plate 3).

[0067] Exemplarily, the aperture of the through hole may be set to be equal to or smaller than the aperture of the hole opening of the adsorption channel 31 on the side away from the rear shell 2 .

[0068] For example, the protrusions and the middle plate 3 can be integrally formed to save manufacturing steps and improve the structural strength of the entire middle plate 3. In addition, the number and position of the protrusions can correspond to the number and position of the adsorption channels 31.

[0069] In some embodiments, the cross-section of the protrusion is circular, and the outer diameter of the protrusion ranges from 3 mm to 5 mm.

[0070] By reasonably setting the outer diameter range of the convex portion, the through hole formed on the convex portion can have a sufficient aperture to facilitate smooth flow of air.

[0071] Exemplarily, the outer diameter of the protrusion may be, for example, 3 mm, or 4 mm, or 5 mm.

[0072] In some embodiments, along the direction from the title card 7 to the middle plate 3, the extension dimension of the protrusion is 0.02 mm-0.06 mm.

[0073] By reasonably setting the extension size of the protrusion in the direction from the question card 7 to the middle plate 3, the setting of the protrusion will not significantly affect the thickness of the entire thinking machine.

[0074] Illustratively, the extension dimension of the protrusion may be, for example, 0.02 mm, or 0.04 mm, or 0.06 mm.

[0075] When the side of the middle plate 3 close to the title card 7 is a smooth surface, the smooth surface can be reliably fitted with the title card 7, so there is no need to provide the above-mentioned convex part.

[0076] Reference Figure 5 and Figure 6 As shown, in some embodiments, a first plug-in portion 111 is provided on a side wall of the installation notch 11, and a second plug-in portion is provided at a position on the question card 7 corresponding to the first plug-in portion 111. The first plug-in portion 111 and the second plug-in portion are plugged together to achieve the plug-in fixation of the question card 7.

[0077] In some embodiments, one of the first plug-in portion 111 and the second plug-in portion is a plug-in protrusion, and the other of the first plug-in portion 111 and the second plug-in portion is a plug-in hole that plugs with the plug-in protrusion, so that the question card 7 can be fixed on the front shell 1 through the plug-in cooperation between the plug-in protrusion and the plug-in hole.

[0078] For example, a plug-in protrusion may be provided on the title card 7, and a plug-in hole may be provided on a side wall of the installation notch 11. Alternatively, a plug-in hole may be provided on the title card 7, and a plug-in protrusion may be provided on a side wall of the installation notch 11.

[0079] Reference Figure 5 and Figure 6 As shown, in some embodiments, a guide surface 112 for guiding the insertion of the question card 7 is provided on the other side wall of the installation notch 11 opposite to the side wall provided with the first plug-in portion 111, so that the guide surface 112 guides the insertion of the question card 7 during the insertion process of the question card 7 until the question card 7 is inserted into place and is fixed by plugging and matching with the first plug-in portion and the second plug-in portion.

[0080] For example, when the first plug-in portion 111 is disposed on the bottom wall of the installation notch 11 , the guide surface 112 is disposed on the top wall of the installation notch 11 , and the insertion direction of the question card 7 is from top to bottom.

[0081] Alternatively, when the first plug-in portion 111 is disposed on the left side wall of the installation notch 11 , the guide surface 112 is disposed on the right side wall of the installation notch 11 , and the insertion direction of the question card 7 is from right to left.

[0082] Illustratively, in this embodiment, a camera module 8 may also be provided on a side of the middle plate 3 away from the question card 7, and an opening for allowing the camera of the camera module 8 to be exposed to the outside is provided at a corresponding position on the middle plate 3, so that the QR code on the question card 7 can be recognized by the camera module 8 to uniquely identify the question card 7.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
