Description

Technical Field

[0001] This invention belongs to the field of children's learning equipment, and in particular relates to an intelligent children's learning desk. Background Technology

[0002] The study desk is a tool made through in-depth research in three major disciplines: ergonomics, biomechanics, and human physiology, combined with the principles of human vision, color science, and psychology. It is the result of countless data collections, experiments, and demonstrations. The study desk is a completely different concept from the traditional desk.

[0003] Existing study desks generally meet children's learning needs, such as tilting the tabletop and adjusting its height. However, when there is insufficient natural light, a desk lamp or indoor lighting is needed to provide adequate illumination. Desk lamps, however, take up considerable space on a small study desk and are difficult to store when not in use. Using indoor lighting often results in insufficient illumination, and manual adjustment of existing desk lamps requires children to get up, thus affecting their learning efficiency. Similarly, existing book clips typically use mechanical mechanisms for extension and retraction, requiring children to adjust them themselves. Given children's height, adjusting the book clips or desk lamps may pose a safety risk. Therefore, a smart children's study desk that automatically adjusts the book clips and desk lamp is urgently needed. Summary of the Invention

[0004] This invention addresses the aforementioned technical problems of safety hazards in existing children's study desks by proposing a smart children's study desk that is reasonably designed, simple in structure, low in cost, and capable of automatically adjusting the book clips and desk lamp.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention provides an intelligent children's study desk, including a desk assembly and a bookshelf assembly disposed above the desk assembly. The bookshelf assembly is provided with a book clip assembly and an LED light. The book clip assembly and the LED light are disposed on the book clip assembly via an intelligent telescopic frame. The intelligent telescopic frame includes a fixed base for fixing to the bookshelf assembly and a first connecting rod hinged to the fixed base. A second connecting rod is hinged to the end of the first connecting rod away from the fixed base, and a connecting base is hinged to the end of the second connecting rod away from the first connecting rod. The connecting base is detachably fixedly connected to the book clip assembly and the LED light.

Each of the left and right lifting leg assemblies includes a fixed leg and a lifting tube fitted inside the fixed leg. The lifting tube is fixedly connected to the desktop assembly and can be raised and lowered inside the fixed leg.

[0010] Preferably, the lifting foot is movable within the fixed foot via a lifting mechanism. The lifting mechanism includes a lifting screw disposed within the lifting foot and a screw nut fitted onto the lifting screw. The screw nut is fixed within the fixed foot. A gearbox for controlling the rotation of the lifting screw is disposed at the top of the lifting screw, and the gearbox is fixed to the top of the lifting foot.

[0011] Preferably, the gearbox includes a gearbox housing and an active output shaft disposed within the gearbox housing. The active output shaft is rotatably disposed within the gearbox housing.

[0025] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, as Figures 1 to 8 As shown, this embodiment aims to provide an intelligent children's study desk to reduce the space occupied by desk lamps and book clips and achieve intelligent operation. To this end, the intelligent children's study desk provided in this embodiment includes a desk assembly and a bookshelf assembly disposed above the desk assembly. In this embodiment, the desk assembly includes a desktop assembly and left and right height-adjustable leg assemblies symmetrically disposed at the bottom of the desktop assembly. The desktop assembly is consistent with the desktop assembly of existing common children's study desks, including a fixed tabletop, a tilting tabletop, and a fixing frame for fixing the tabletop. In this embodiment, no improvements are made, so they are not described in detail in this embodiment.

[0028] The bookshelf assembly includes a left side panel, a right side panel, shelves, a back panel assembly, and drawers. The left and right side panels face each other and are both located above the desktop assembly and fixedly positioned relative to it. One end of the back panel assembly is perpendicularly fixed to the rear edge of the left side panel, and the other end is perpendicularly fixed to the rear edge of the right side panel. One end of the shelf assembly is perpendicularly fixed to the surface of the left side panel, and the other end is perpendicularly fixed to the surface of the right side panel. The back panel assembly includes a back panel, a lamp holder / book clip connector, and a magnetic plate. The above structure is a common existing structural configuration and may vary slightly. Since this structure is not an improvement in this embodiment, it will not be described in detail here.

[0029] The bookshelf assembly is equipped with a book clip assembly and an LED light. Specifically, a through hole is provided in the middle of the back panel, and the connectors for the book clip assembly and the LED light pass through the front and back of the through hole. To reduce floor space while achieving intelligent telescopic adjustment, in this embodiment, the book clip assembly and LED light are mounted on the book clip assembly via an intelligent telescopic frame. Specifically, the intelligent telescopic frame includes a fixed base for fixing to the book clip assembly and a first connecting rod hinged to the fixed base. A second connecting rod is hinged to the end of the first connecting rod away from the fixed base, and a connecting seat is hinged to the end of the second connecting rod away from the first connecting rod. The connecting seat is detachably fixed to the book clip assembly and LED light. The fixed base and the first connecting rod, the first connecting rod and the second connecting rod, and the second connecting rod and the connecting seat are hinged via a micro-motor damping shaft. Thus, the fixed base, the first connecting rod, the second connecting rod, and the connecting seat constitute the structure of a commonly used four-section hinged rod. By setting a micro-motor damping shaft at its hinge point, and controlling the rotation of the micro-motor, control is achieved at each hinge position, thereby realizing intelligent telescopic control of the book clip assembly and LED light, thus solving the technical problems existing in mechanical control.

[0030] Of course, the desk assembly also includes a control assembly for controlling the damping shaft of the micro-motor. In this embodiment, the control assembly includes an intelligent control electronic board, a touch button board, and an infrared sensor module; the intelligent control electronic board includes an LED lighting driver output module and a bookshelf assembly driver output module, a power input terminal, N motor output terminals, and N control trigger terminals; the control trigger terminals include: a power button, an infrared start button, an illuminance button, a color temperature button, a learning mode button, a lamp holder extension button, and a bookshelf extension button. The lamp holder extension button has height, extension, and level buttons; the bookshelf extension button has height, extension, and tilt buttons. Since this type of control is simply the control of the micro-motor and LED lighting, which is a mature existing technology, its related circuit diagram is not provided in this embodiment.

[0031] To better control the LED lighting and bookshelf assembly, this embodiment also provides a micro-motor damping shaft, including a shaft housing and a micro-motor assembly with dual output shafts fitted inside the shaft housing. In this embodiment, the shaft housing is cylindrical, and the micro-motor assembly is a dual-output shaft micro-motor assembly. Similar to existing motors, the micro-motor assembly provided in this embodiment includes a dual-output shaft rotor and a stator fitted outside the dual-output shaft rotor. The stator is fixedly connected to the shaft housing. Specifically, a retaining ring is provided inside the shaft housing to fit the micro-motor assembly inside the shaft housing.

[0032] Damping blocks are connected to both ends of the micro motor assembly. In this embodiment, the damping block is a hexagonal fixed block with a placement slot on it. The placement slot is used to place a micro torque detection probe for detecting changes in the torque of the damping block. The micro torque detection probe can be a probe from a commonly used torque detector. In this embodiment, it is a metal resistance strain gauge, which is an element used to measure strain. It converts changes in strain on a mechanical component into changes in resistance. It is made by winding constantan wire or nichrome wire with a diameter of 0.02-0.05 mm into a grid shape (or by etching a grid shape from a very thin metal foil) and sandwiching it between two layers of insulating sheets (substrate). Tinned copper wire is used to connect the strain gauge wire grid as the strain gauge lead wire, which is used to connect the measuring wire. In this way, when the damping block rotates, the metal resistance strain gauge undergoes a certain change, resulting in a change in resistance. The angle of rotation of the damping block can then be derived from the amount of change in resistance.

[0033] To achieve precise control of the micro-motor assembly, in this embodiment, a flexible control electronic board is also provided between the shaft housing and the dual-output shaft micro-motor assembly for controlling the rotation of the dual-output shaft micro-motor assembly based on the magnitude of the damping block torque. To facilitate use and simplify the control structure, in this embodiment, the micro-torque detection probe is a metal resistance strain gauge. The flexible control electronic board includes a flexible printed circuit board and, on the flexible printed circuit board, a current detection circuit module for detecting current magnitude, a current amplification circuit module for amplifying current, a control chip for implementing control (in this embodiment, the control chip is an integrated current sensor, specifically model MLX91210KDC-CAS-101-SP, manufactured by Worldway Advanced (Shenzhen) Technology Co., Ltd.), a power input terminal, a power output terminal, and a signal input terminal connected to the micro-torque detection probe. The micro-torque detection probe is electrically connected to the flexible control electronic board.

[0034] In this way, the resistance of the metal resistance strain gauge changes, and the signal is transmitted to the control chip through the signal input terminal. The control chip determines whether there is a change based on the pre-set threshold. If there is a change, the current amplification circuit module is turned on to amplify the current, thereby controlling the current of the micro motor assembly to increase the output shaft torque and maintain stability. When the resistance is within the threshold range and there is no change, the current amplification circuit module is not turned on, and the power supply current only passes through the current detection circuit module to maintain the original current magnitude.

[0035] Considering the excessively high speed and low torque of the micro motor assembly, in this embodiment, a micro reducer is also provided between the micro motor assembly and the damping block, distributed at both ends of the micro motor assembly. The sun gear is axially fixed to the motor, and the damping block is connected to the power end of the micro reducer, thereby realizing the speed reduction control of the micro motor assembly and increasing the output torque.

[0036] To facilitate the use of the entire damping shaft, at least two raised ribs are provided on the outer wall of the shaft housing. The main function of the raised ribs is to fix them with the grooves of the fixing rod, forming a locking structure to prevent relative rotation.

[0037] To ensure the airtightness of the shaft housing, caps are installed at both ends of the housing, positioned between the damping block and the micro reducer. The caps have through holes for wiring to pass through. The use of these caps provides a better seal.

[0038] In this way, when any micro-motor damping shaft is positively energized, the micro-motor damping shaft rotates upward at an angle, causing the connecting rod and the LED light or book clip assembly to tilt upward at an angle. The vertical gravity of the connecting rod and the LED light or book clip assembly also changes. The resistance change of the damping block installed on the micro-motor damping shaft and the metal resistance strain gauge inside the damping block is higher than the threshold in the control chip program. The current amplification circuit module is turned on, and the current is amplified to supply the micro-motor assembly to work. The micro-motor assembly increases the output shaft torque, which also increases the torque of the damping block, offsetting the increase in vertical gravity of the LED light or book clip assembly as the angle increases, ensuring the stability of the LED light or book clip assembly at this tilt angle.

[0039] In this embodiment, for ease of processing, the fixing seat, the first connecting rod, the second connecting rod, and the connecting seat adopt a combined structure. Specifically, it consists of a U-shaped connecting recess, a U-shaped connecting protrusion, and a connecting tube. The connecting recess and the connecting protrusion can be inserted into the connecting tube. With this arrangement, mass production and arbitrary assembly are possible, and the length of different accessories can be easily adjusted to meet the needs of different LED lighting lamps or book clip assemblies.

[0040] To reduce floor space and provide a more intelligent LED lighting fixture, this embodiment also provides an LED lighting fixture. Specifically, the LED lighting fixture includes an upper lampshade shell and a lower lampshade shell that is configured in a straight-line shape to cooperate with the upper lampshade shell. An LED light strip is disposed within the lower lampshade shell. A left and right light-reflecting plate are symmetrically arranged on the lower lampshade shell. A sensor is disposed between the left and right light-reflecting plates and is electrically connected to a control assembly. In this embodiment, the sensor is an infrared sensor. The infrared sensor is connected to the circuit components inside the LED lighting fixture. The LED lighting fixture can sense the intensity of infrared radiation through the infrared sensor installed on it, and then convert this change in the intensity of infrared radiation into an electrical signal, thereby controlling the on / off state of the LED light fixture, achieving the purpose of energy saving and environmental protection.

[0041] To achieve intelligent book clamping, this embodiment provides a book-clamping panel and a book-clamping base plate that are box-shaped and fitted together. In this embodiment, the book-clamping panel and the book-clamping base plate together form a rectangular book-clamping body, the overall length of which is basically the same as the length of an existing book. It should be noted that, to facilitate book holding, a groove is formed in the middle of the book-clamping panel in this embodiment to accommodate the placement of the book. To provide support on both sides of the page-turning book, a left book clip and a right book clip are provided on both sides of the book-clamping panel. The left and right book clips are rotatably fixed on both sides of the book-clamping panel. The rotation of the left and right book clips can be controlled by a motor or by a mechanical structure, such as a torsion spring.

[0042] Considering the varying sizes of books, a left-side movable plate and a right-side movable plate are provided on both sides of the book-clamping panel. The clamping motor is fixed to the side of the left and right movable plates furthest from the book-clamping panel. The left book clip is positioned on the left side of the book-clamping panel via the left movable plate, and the right book clip is positioned on the right side via the right movable plate. The left and right movable plates are retractable on both sides of the book-clamping panel. This allows for the enlargement of the entire book clip using the left and right movable plates, accommodating books of different sizes.

[0043] To achieve automatic control of the left and right movable plates, in this embodiment, the left and right movable plates are telescopically mounted on both sides of the book-clamping panel via a synchronous telescopic mechanism assembly. Specifically, the synchronous telescopic mechanism includes a telescopic motor installed at the center of the book-clamping base plate, a driving gear installed on the output shaft of the telescopic motor, a driven left rack meshing with the upper end of the driving gear, and a driven right rack meshing with the lower end of the driving gear. The driven left rack is fixedly connected to the left movable plate, and the driven right rack is fixedly connected to the right movable plate. Thus, by rotating the telescopic motor forward or backward, the left and right movable plates can move in opposite directions, facilitating the clamping of books of different sizes.

[0044] Considering the needs of children of different heights and different learning scenarios, the height of the desktop needs to be adjusted. Therefore, the left and right lifting foot assemblies provided in this embodiment both include a fixed foot and a lifting tube fitted inside the fixed foot. In this embodiment, the fixed foot is arranged in an inverted T-shape. The lifting tube is fitted inside the vertical part of the fixed foot. The lifting tube is fixedly connected to the desktop assembly and can be raised and lowered inside the fixed foot.

[0045] Specifically, the lifting foot is height-adjustable within the fixed foot via a lifting mechanism. This mechanism includes a lifting screw housed within the lifting foot and a screw nut mounted on the lifting screw. The screw nut is fixed within the fixed foot. Since the screw nut is fixed within the fixed foot, and the fixed foot is placed on the ground, rotation of the lifting screw will only cause the fixed foot to move up and down when the fixed foot cannot move. To facilitate control of the lifting screw's rotation, a gearbox is installed at the top of the lifting screw to control its rotation. The gearbox is fixed to the top of the lifting foot. Thus, by controlling the rotation of the lifting screw, the lifting foot is raised and lowered, thereby driving the desktop assembly to rise and fall.

[0046] The gearbox includes a gearbox housing and an active output shaft disposed within the gearbox housing. The active output shaft is rotatably mounted within the gearbox housing. One end of the active output shaft is provided with an active bevel gear, and the gearbox housing also provides a driven bevel gear. The active and driven bevel gears are meshed with each other. The driven bevel gear is coaxially fixed to the lifting screw. The active output shaft passes through the gearbox housing, and the end of the active output shaft away from the active bevel gear is connected to a drive mechanism. Specifically, a hexagonal groove is provided at the end of the active output shaft. The drive mechanism controls the active output shaft through the groove. The drive mechanism can be a motor or a crank. Considering the limited number of times the desktop assembly can be raised, and to prevent accidental operation by children, a crank is used in this embodiment.

[0047] To achieve coordinated control of the left and right lifting foot assemblies, the two ends of the active output shaft are installed through the gearbox housing, and a transmission rod is installed between the two active output shafts. In this way, the overall lifting can be achieved by controlling the gearbox on one side.

[0048] In practical operation, when the indoor lighting is insufficient and learning is required, the power button on the trigger end of the control assembly is pressed, and the infrared start button is triggered. When the child's body, such as hands, face, or head, is within the detection range of the infrared sensor module, the infrared sensor module outputs a high level to drive the LED driver output module to conduct, and the LED strip emits the preset lighting light. If the brightness is not satisfactory, the illuminance button can be pressed to increase the brightness; if the color of the light is not satisfactory, the color temperature button can be pressed to adjust the white light to yellow light. When the child leaves and the body, such as hands, face, or head, is no longer within the detection range of the infrared sensor module, the infrared sensor module outputs a low level, the LED driver output module output is turned off, and the LED strip is extinguished.

[0049] Simultaneously, reminder settings can be configured. For example, after the LED light strip has been working for 45 minutes, the program can be set so that the LED light receives flashing power to remind children to rest during their studies. If a child feels that the LED light is not in the correct position, they can press and hold the extend or retract button on the smart telescopic bracket that triggers the LED light. This will cause the intelligent control board to control the corresponding micro-motor in the trigger terminal to receive a low-level signal, driving the motor output terminal to output positive current. The micro-motor's damping shaft will rotate forward, moving the LED light to the desired position.

[0050] Similarly, when a child thinks the book clip assembly is not in the correct position during learning, they can press the extend or retract button of the book clip assembly. This will trigger the corresponding micro motor in the trigger terminal of the intelligent control electronic board to obtain a high-level signal, drive the motor output terminal to output current, and rotate the damping shaft of the micro motor until the book clip assembly is in the desired position.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
