Referring to Fig. 1-Fig. 21, an intelligent learning table includes a base 110, the base 110 is provided with a base side plate 111, and a table board 120 is installed on the top of the base 110, and the table board 120 is fixed with The first vertical plate 131, the second vertical plate 132, the third vertical plate 133, the top of the third vertical plate 133 is close to the protective shell 150, the protective shell 150 is fixed on the fourth vertical plate 134, the fourth vertical plate Between 134 and the first vertical plate 131, the first partition plate 121, the second partition plate 122, and the third partition plate 123 are sequentially installed from top to bottom. Between the first partition plate 121 and the second partition plate 122 forming a first placement groove; forming a second placement groove between the second partition and the third partition 123;

There are two second vertical boards 132, and the tops of the two second vertical boards 132 are connected and fixed by the fourth dividing plate 180. The fourth dividing plate 180 is fixed with the control host 240 and the upper fixing block 181. The above-mentioned control host 240 is equipped with a light sensor switch 250, which is used to control the on-off of the light bar 230. A light source is installed on the light bar 230. emit light, thereby providing illumination. The light bar 230 is provided with a lower fixing block 231, and the upper fixing block 181 and the lower fixing block 231 are hinged through the light bar rotating shaft 232. When in use, the light bar 230 can rotate around the light bar rotating shaft 232, Thereby adjusting the lighting angle. This design directly integrates the lamps and lanterns, which can effectively save space. At present, desk lamps are generally purchased in addition, which undoubtedly takes up a certain amount of space and has limited lighting effects.

The control host 240 has a built-in PLC (or single-chip microcomputer). When in use, the PLC sends and receives control commands, controls the operation of various electrical equipment, and communicates with various equipment;

The table board 120 is located in the grid between the two second vertical boards 132 and a display 220 is installed. The display 220 communicates with the computer host 210, and the display 220 and the computer host 210 together constitute a desktop computer. This design mainly takes into account the development of Internet technology, and it is inevitable to use computers to search and study materials when studying.

A sliding partition 160 is installed in the first placement groove and the second placement groove, and a partition through groove 161 is arranged on the sliding partition 160, and a book pressing assembly is respectively installed in the first placement groove and the second placement groove B, the two ends of the sliding partition 160 are respectively assembled and fixed with the shaft plate 170;

The book pressing component B includes a book pressing power block B110, and the book pressing power block B110 is assembled and fixed with the book pressing shell B120 after passing through the partition slot 161, and the book pressing power block B110 is provided with There is a power screw hole B111, and the book press shell B120 is provided with a book press board B130 on the side facing the fourth vertical plate 143, the book press board B130 is assembled and fixed with one end of the book press shaft B210, and the other end of the book press shaft B210 is loaded into the press Inside the book shell B120 and assembled with the book pressure nut B310 by threading, so as to limit the maximum distance that the book pressure shaft B210 can move to the book pressure plate B130;

A book pressure spring B410 is arranged between the book pressure plate B130 and the book pressure shell B120, and the book pressure spring B410 is preferably set on the book pressure shaft B210;

The first sensing block B511 and the first matching sensing block B512 are respectively installed on the end faces of the book pressing shell B120 and the book pressing board B130 close to each other. The first sensing block B511 and the first matching sensing block B512 are respectively connected to the second An induction circuit is connected, and the first induction circuit includes a battery, the negative electrode of the battery is connected with the first induction block B511 for conduction, the positive electrode of the battery is connected with the positive electrode of the resistor for conduction, the negative electrode of the motor is connected with the positive electrode of the current sensor for conduction, and the current The negative electrode of the sensor is electrically connected to the first sensing block B511, and the current sensor is connected to the PLC in communication. In the initial state, the first sensing block B511 and the first matching sensing block B512 are separated under the action of the book pressing spring, the first sensing circuit does not form a loop, and the current sensor has no signal. When the first sensing block B511 and the first cooperating sensing block B512 overcome the elastic force of the book pressing spring, the first sensing circuit forms a loop, the current sensor generates a signal, and transmits the signal to the PLC. After receiving the signal, the PLC judges that the pressing The pressure on the book board is relatively large, so that the book pressing component B is controlled to retreat. Until the first sensing block B511 and the first mating sensing block B512 are separated, the current sensor has no signal. This design is mainly to prevent the book pressing component B from pressing the book blindly, resulting in excessive pressing to damage the book or burn out the motor (the motor is easily burned out if it is stuck), and it can also prevent the hand from being pinched.

When in use, first put the book away, then drive the book pressing assembly to press the book against the fourth vertical plate until the first induction block B511 and the first matching induction block B512 are in contact with conduction, and then the book pressing assembly retreats 4-6cm , so that the book pressure plate B130 is closely attached to the book, and at the same time, the first induction block B511 and the first matching induction block B512 are separated. At this time, the book pressure plate B130 compresses the book by the elastic force of the book pressure spring, but the pressure is not large. But it can fix books. This design makes it very convenient for the user to take out the books. Once the pressure between the books is too large, it will be difficult to take out the books and the books will be easily damaged.

In addition, since there is an adjustable gap of 4-6 cm, the user can insert and place books at any time, without having to adjust the book pressing assembly again before placing books, which is very convenient to use. After the user inserts the book, if the first sensing block B511 and the first mating sensing block B512 are in contact again, the book pressing assembly continues for 4-6 cm on the rear legs, thereby freeing up the insertion space.

Preferably, since generally books need a lot of pressure if they are placed vertically, and it is inconvenient to take and place, therefore, the applicant has provided an insertion hole B131 on the book pressure plate B130, and the insertion hole B131 is inserted and assembled with the insertion rod B610 , the inserting rod B610 is fixed on the convex plate B600, and the convex plate B600 is provided with a pressure surface B602 and a connecting inclined surface B601, and the pressure surface B602 protrudes from the outer surface of the book pressure plate B130. This design makes the book in an inclined state when it is compressed, which is more beautiful on the one hand, and more convenient to take and insert on the other hand.

Preferably, since there are many books, it is possible to cause the first sensing block B511 and the first mating sensing block B512 to contact but the books are still not compressed, because each book has friction, once this happens, it will It makes the book pressing component B relatively tasteless, so the applicant makes the following improvements:

When the second induction block and the second matching induction block overcome the elastic force of the induction spring and stick tightly, the second induction circuit forms a loop, the current sensor generates a signal, and transmits the signal to the PLC. After receiving the signal, the PLC judges that the pressure on the induction plate At this time, if the first induction circuit forms a loop, it is judged that the book pressing is completed, and then the book pressing assembly retreats. The induction spring drives the induction plate to move toward the book pressing assembly until the second induction block B721 and the second mating induction block B722 are separated.

The third auxiliary pulley C632 is installed at one end of the output shaft C631, and the output shaft C531 passes through the third tangential relief groove C3141 of the fourth vertical partition C314 and is loaded into the motor C530, which can drive the output shaft around direction, and the motor C530 is a bidirectional motor, that is, it can be rotated forward and reverse.

The upper and lower sides of the motor C530 are respectively assembled and fixed with the upper motor board C322 and the lower motor board C323, and the lower connecting plate C810 is fixed on the bottom of the lower motor board C323 away from the output shaft, and the lower connecting board C810 passes through the motor The rotating shaft C830 is hinged to the top of the supporting shaft C820, which allows the lower motor plate to rotate through the motor shaft;

The support shaft C820 is installed in the rotation hole C3241 of the second diaphragm C324, and the support shaft C820 can rotate circumferentially in the second diaphragm C324, and the bottom of the support shaft C820 is provided with a stop ring C821 , the anti-retraction ring C821 is used to prevent the support shaft from moving in the axial direction. Assembly is fixed.

The structures of the first tangential relief groove, the second tangential relief groove and the third tangential relief groove are the same. Referring to Fig. 17, the first tangential relief groove C3121 is inclined upward and inclined The direction is obliquely upward from the second gear to the first gear.

In the initial state, the third gear C413 meshes with the second gear C412, the third power shaft C130 is located at the lowest point of the first tangential relief groove C3121 and the second tangential relief groove C3131, and the output shaft C531 is located at the third tangential relief groove. At the lowest point of the slot C3141, the motor can drive the second drive shaft 320 to rotate, that is, it can drive the book pressing assembly in the second placement slot to move.

The upper motor plate C322 is fixed with an installation protruding shaft C150, the installation protruding shaft C150 is assembled and fixed with the bottom of the motor spring C550, and the top of the motor spring C550 is assembled and fixed with the first diaphragm C321. This design makes the motor spring always press the upper motor plate, thus ensuring the stable operation of the motor.

The third power shaft C130, the first tangential relief groove, and the second tangential relief groove are respectively sleeved with a collar C710. The inner surface of the second tangential relief groove is closely rolled, thereby reducing the degree of wear on the inner surface of the first tangential relief groove and the second tangential relief groove;

A shaft cylinder C720 is arranged between the two collars C710, and the shaft cylinder C720 and the third power shaft C130 can be rotated and assembled in the circumferential direction, and one end of the shaft cylinder C720 is assembled and fixed with the telescopic shaft C511, and the other end of the telescopic shaft C511 is assembled with the electromagnet C510 , the electromagnet C510 can drive the telescopic shaft C511 to move in its axial direction;

The casing of the electromagnet C510 is rotatably assembled with the electromagnetic mounting plate C315 through the electromagnetic rotating shaft C160, and the electromagnetic mounting plate C315 is fixed on the first transverse partition C321. When it is necessary to drive the pressing book assembly in the first placement slot, the electromagnet C510 is energized to extend the telescopic shaft C511, so that the third power shaft C130 moves upward along the first tangential relief groove and the second tangential relief groove , until the collar C710 reaches the highest point of the first tangential relief groove and the second tangential relief groove, at this time, the first gear C411 and the third gear C413 are meshed for transmission. During this process, the third power shaft drives the output shaft C531 to move along the first tangential relief groove through the third belt C213, and the motor adjusts its position through the rotation of the motor shaft and the support shaft. At the same time, due to the compression of the motor spring , On the one hand, it can play a role of pressing and stabilizing the motor, on the other hand, it can produce a tension effect on the third belt, thereby preventing the third belt from loosening.

Preferably, a second collar C730 can be installed on the third power shaft C130, the second collar C730 can be assembled with the third power shaft in a circumferential direction, and the second collar C730 can be assembled and fixed with one end of the extension spring C540 , the other end of the extension spring C540 is assembled and fixed with the spring shaft C140, and the spring shaft C140 is fixed on the third vertical partition C311. The installation position of the spring shaft C140 is lower than the lowest point of the first tangential relief groove. This design makes the third power shaft C130 stretch the tension spring when it moves to the top of the first tangential relief groove, thereby The tension spring stores elastic force, and provides power for auxiliary reset of the third power shaft when the third power shaft needs to be reset. Of course, a similar structure can be provided on the second vertical partition C312 and the third power shaft, so that the reset of the third power shaft is more stable and fast.

The outside of the power assembly C is closed by a power door 140, and the power door 140 and the protective case 150 are both made of transparent materials, and the protective case 150 is covered outside the first belt and the second belt. This design allows the user to observe the operation of the power components intuitively. During the high-intensity learning process, it can disperse the user's sight, allowing the user to take a short rest and play a role in decompression. Its principle is similar to that of fingertips. The gyro is basically the same.

In addition, the main purpose of using the same motor to drive the first drive shaft and the second drive shaft is to prevent misoperation, because if different motors are used separately, it is likely to be activated incorrectly during use, causing hand pinching. In this case, the motor is used to drive the second drive shaft by default. On the one hand, the frequency of use of the second placement slot is high, and on the other hand, it is easy for the operator to keep in mind, so as to avoid misuse. In addition, this is also a way to save costs. Although the number of components is increased, but one motor is reduced, the cost does not increase in terms of manufacturing cost, and it is slightly reduced. Moreover, if the motor is not used for a long time, it is easy to be damaged. If two motors are used, the motor driving the first drive shaft must not be used frequently, which will cause it to be shelved for a long time, resulting in increased maintenance and repair costs in the later period. And this case adopts the mode of a motor, an electromagnet and other mechanical structures to be more solid and durable. According to the applicant's actual calculation, the cost difference between the method of using two motors and the method of using one motor in this case is about plus or minus 30 yuan, and minus 30 yuan means that the method in this case is 30 yuan more expensive. On the whole, this cost change can be controlled and can be ignored.

See Figures 19-21, because in actual use, the area of the table is likely to be insufficient. For example, when others are tutoring or placing other files, it is either crowded or additional tables are used together, which is very inconvenient , therefore, the applicant adds expansion component A to expand the table area;

The expansion assembly A includes a baffle plate A310 fixed on the outside of the base side plate 111, a hinge plate A320, and an expansion plate A100. The expansion plate A100 is assembled and hinged with the table plate 120 through the hinge A610, and the There is a rotating groove A101 between the expansion board A100 and the table board 120, the expansion board A100 and the top surface of the table board 120 are connected through the protective sheet A200, and the protective sheet A200 is used to close the rotating groove A101 to prevent it from pinching the user;

The guide slide A110 is fixed on the bottom surface of the expansion board A100, and the guide slide A110 is provided with a guide chute A111 and a locking slot A112. The guide chute A111 and the first roller A511 can be slidably assembled, and the first pin The shaft A511 is installed on one end of the support rod A410, and the other end of the support rod A410 is rotatably assembled with the hinge plate A320 through the second pin shaft A512;

The first pin shaft A511 can be inserted into the locking slot A112, and a torsion spring is installed between the support rod A410 and the hinge plate A320, and the torsion spring is used to make the support rod A410 generate a force to rotate toward the expansion plate , so that when the first pin shaft is assembled with the locking slot, the torsion spring provides a rotational force to the support rod A410 to prevent the first pin shaft from leaving the locking slot, and the gravity of the expansion board also has this function.

Figure 1 is the initial state of the expansion kit, and Figure 2 is the use state of the expansion assembly. In the initial state, the expansion board does not exceed the baffle A310, and the first pin A511 is located at the lowest point of the guide chute A111. When it needs to be used, turn the expansion board upwards with the hinge as the center by hand. At this time, the first pin shaft will slide in the guide chute A111. When the expansion board is parallel to the table or slightly higher than the table, the locking gap The slot is assembled with the first pin shaft, and then the expansion board is released, and the expansion board relies on its own gravity to clamp the first pin shaft in the locking slot. At this time, the desktop expanded by the expansion board can be used, which is very convenient.

Referring to Figure 21, in actual use, the protective sheet A200 will be subject to a relatively large pulling force, resulting in a short lifespan. Therefore, the applicant makes the following improvements:

The two ends of the protective sheet A200 are respectively provided with fixed parts A210, and the two fixed parts A210 are connected by a folded part A220. When the unfolded plate is used, the folded part A220 is in the state of being bent in the rotation groove A101. When the unfolded plate is retracted, The folded part A220 is opened, thereby avoiding the stretching of the protective sheet and effectively protecting the protective sheet.
