Description

Technical Field

[0001] The present invention relates to the technical field of study tables, and in particular to a language study table that can be controlled by gestures. Background Art

[0002] Study tables are functional furniture designed specifically for learning environments. They are widely used in homes, schools, training institutions, and other places, primarily to support learning activities such as writing, reading, and storing stationery and electronic devices. With the advancement of educational concepts and the refinement of user needs, study tables have gradually evolved from a simple "table and chair combination" to an intelligent, healthy, and personalized design.

[0003] Traditional table top angle adjustment mostly relies on manual buckles or bolts. The adjustment process is cumbersome and the angle locking accuracy is insufficient. There is a lack of a reliable physical locking structure after the angle adjustment. The angle may shift due to external force collision, affecting the safety of use. The protective structure cannot be automatically adjusted according to the tilt angle, resulting in books easily sliding off due to the tilt of the desktop when writing, requiring frequent manual intervention by the user. At the same time, in addition, the position of the lamp is usually fixed, and the illumination angle cannot be dynamically adjusted according to the user's writing position or ambient light, which easily produces shadows or reflections, increases eye fatigue, and is difficult to meet the lighting requirements in different learning scenarios.

[0019] Working principle: Before using the study table, first adjust the height of the study table by lifting the support legs, then turn the butterfly plate to drive the screw to rotate, loosen the connection between connecting rod 2, connecting rod 3 and table board 1, and then turn connecting rod 3. When rotating connecting rod 3, since connecting rod 3 is parallel to connecting rod 1 and both are connected to the top plate, the position of the lamp can be stably adjusted when connecting rod 3 is rotated. When it is adjusted to the appropriate position, rotate the butterfly plate in the opposite direction to prevent connecting rod 3 from rotating through the screw, and under the action of the gasket and spring, the thread engagement between the screw and table board 1 can be tighter. Then, make corresponding gestures to the camera to control the brightness of the lamp, and you can study on table board 2 or learn a language through the display screen. When you need to adjust the tilt angle of table board 2, turn the knob to drive the worm to rotate, so that the worm gear can drive the rotating rod to rotate, and then adjust the angle of table board 2. While adjusting the angle, the rotating rod will drive the gear to rotate, and under the action of the tooth plate, the baffle 1 is driven up and down through the fixed plate to limit the learning materials on table board 2 to prevent them from falling.

[0020] The present invention provides a language learning table that can be controlled by gestures. It has the following beneficial effects:

[0021] 1. The present invention uses a worm and worm gear transmission mechanism to achieve the adjustment of two angles of the table top, meeting the needs of multiple scenarios such as writing, reading, and drawing, reducing the fatigue caused by users maintaining a single posture for a long time, and cooperating with the groove limit design of the limit frame to provide physical gear locking to avoid automatic offset of the angle after adjustment, thereby improving safety of use.

[0022] 2. The present invention uses a gear and toothed plate linkage mechanism to synchronize the angle adjustments of baffle 1 and table top 2. When the angle increases, baffle 1 automatically rises to form a highly matched guardrail. When the angle decreases, baffle 1 drops and resets without blocking the desktop space. No manual operation is required, and it intelligently adapts to different tilt angles, effectively preventing books and stationery from sliding due to the tilt of the desktop.

[0023] 3. The present invention uses a four-link mechanism consisting of link 1, link 2 and link 3 in conjunction with a screw locking structure to achieve the top plate driving the lamp to move. Users can adjust the lamp to the optimal illumination angle according to the writing position or ambient light, such as facing the writing area or avoiding the reflective angle, which can reduce shadow interference, reduce eye fatigue, and improve learning comfort.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example:

[0034] Please see the attached Figure 1 -Attached Figure 7 The embodiment of the present invention provides a language learning table that can be controlled by gestures, including a table board 3, wherein the left and right ends of the table board 3 are connected to a top plate 19 through a connecting rod 18, and the two ends of the two connecting rods 18 are connected to a connecting rod 3 26 through a connecting rod 22.

Connected to the left and right ends of table board 1 3, the bottom end of table board 1 3 is fixedly connected to a storage slot 6, the top of the storage slot 6 is connected to table board 2 15 through a stabilizing component, the inner wall of table board 1 3 is connected to a rotating rod 10 through an adjusting component, the rotating rod 10 is rotatably connected to the bottom end of table board 2 15, the outer wall of the rotating rod 10 is connected to baffle 14 through a lifting component, the baffle 14 is slidably connected to the inner wall of table board 2 15, the bottom end of the top plate 19 is fixedly connected to a lamp 21, and the bottom end of the top plate 19 is fixedly connected to a camera 20;

[0035] Specifically, rotating the butterfly plate 24 drives the screw 23 to rotate counterclockwise, releasing the threaded lock between the connecting rod 3 26 and the table board 1 3. At this time, the limit rod 27 in the connecting rod 22 is slightly lifted up under the elastic action of the spring 28, so that the four-bar mechanism composed of the connecting rod 18, the connecting rod 22, and the connecting rod 3 26 enters an active state. Manually rotating the connecting rod 3 26 can drive the top plate 19 to move through the parallelogram connecting rod structure to adjust the illumination angle and position of the lamp 21. Turning the knob 7 drives the worm 8 to rotate, and the engaged worm gear 9 drives the rotating rod 10 to rotate synchronously, thereby changing the inclination angle of the table board 2 15, which can be adapted to scenes such as writing and reading. The gear 11 on the outer wall of the rotating rod 10 rotates with the rotating rod 10, meshing with the tooth plate 12 for transmission, pushing the fixed plate 13 to lift and lower the baffle 14. For example, when the inclination angle of the table board 2 15 increases, the baffle 14 automatically rises to form a highly adapted limit baffle to prevent books from slipping.

[0036] Among them, the screws 23 located on the inner walls of the two connecting rods 3 26 are both threadedly connected to the inner wall of the table board 1 3, and the two screws 23 are fixedly connected to the butterfly plate 24 at one end. The outer walls of the two connecting rods 3 26 are provided with gaskets 25.

Among them, the limit frame 17 at the top of the storage slot 6 is provided with a plurality of equidistant grooves at the top of the limit frame 17. One end of the support rod 16 is provided in one of the grooves at the top of the limit frame 17, and the other end of the support rod 16 is rotatably connected to the bottom end of the table board 2 15. A worm 8 is located on the inner wall of a table top 3, and the bottom end of the worm 8 is meshedly connected to a worm wheel 9, the outer wall of the worm wheel 9 is rotatably connected to the inner wall of the table top 3, the inner wall of the worm wheel 9 is fixedly connected to the inner wall of the rotating rod 10, the front end of the worm 8 is fixedly connected to a knob 7, and the rear end of the knob 7 is rotatably connected to the front end of the table top 3, wherein a gear 11 is located on the outer wall of the rotating rod 10, the front end of the gear 11 is meshedly connected to a toothed plate 12, the front end of the toothed plate 12 is fixedly connected to a fixed plate 13, the fixed plate 13 is fixedly connected to the bottom end of a baffle 14, the bottom end of the table top 3 is fixedly connected to a cabinet 4, the inner wall of the cabinet 4 is slidably connected to a drawer 5, the top of the table top 3 is fixedly connected to a baffle 29, the front end of the baffle 29 is provided with a display screen 30, the bottom end of the table top 3 is fixedly connected to a fixing frame 2, and the bottom end of the fixing frame 2 is fixedly connected to a lifting support leg 1;

[0037] Specifically, the lifting structure inside the lifting support leg 1 can be adjusted to suit users of different heights. When the lamp 21 is adjusted, the butterfly plate 24 is rotated in the opposite direction, and the screw 23 is screwed back into the table board 1 3. The friction area is increased by the gasket 25, and the reset pressure of the spring 28 is cooperated to achieve double locking, ensuring that the top plate 19 is stable and does not shake. The table board 2 15 is supported by the support rod 16, and its bottom end is embedded in the groove at the top of the limit frame 17. Different grooves correspond to different inclination angles, providing multi-level mechanical limits to avoid shaking during adjustment. The display screen 30 integrates language learning software and supports touch interaction. The cabinet 4 and the drawer 5 cooperate to form a three-dimensional storage space. The drawer 5 is used to store high-frequency items such as stationery and notebooks to keep the desktop tidy. A guide rail sliding structure is used between the cabinet 4 and the drawer 5, which can be pulled out. When the table board 2 15 is tilted, the storage slot 6 can receive stationery and paper that slide off the desktop to prevent items from falling directly to the ground.

[0038] The following steps are involved:

[0039] Step 1: Use the camera 20 fixedly connected to the bottom of the top plate 19 to capture the user's hand movement images or videos in real time to obtain gesture data;

[0040] Step 2: The collected gesture data is transmitted to the processor built into the learning table, and the gesture type and amplitude are analyzed using image recognition algorithms;

[0041] Step 3: The processor generates corresponding lighting control instructions based on preset gesture and function mapping rules. Sliding your finger upward or downward within the shooting range of the camera 20 triggers the brightness of the lamp 21 to increase or decrease.

[0042] Step 4: The processor transmits the control instruction to the driver module of the lamp 21 through the wired or wireless communication module to adjust the luminous intensity of the lamp 21;

[0043] Specifically, the user makes a preset gesture within the shooting range of the camera 20, such as sliding the finger up and down. The camera 20 captures the gesture data and transmits it to the built-in processor. After being analyzed by the image recognition algorithm, the driver chip of the lamp 21 is controlled through the wireless module to adjust the brightness in real time.
