[0002] With the continuous advancement of modern educational concepts, the design of study desks has gradually evolved from single-function to multi-functional and intelligent. Traditional study desks have a fixed height, which cannot be adjusted according to individual preferences or accommodate the height changes of students of different ages. Long-term use may lead to poor posture and affect students' physical health.

[0003] Currently, there are height-adjustable study desks on the market that allow for manual or electric adjustment of the desk legs to adjust the desktop height.

[0052] like Figure 1-6As shown in the figure, this application embodiment provides a height-adjustable study desk control system. The study desk includes height-adjustable desk legs 100. The control system includes a drive crank 1, a drive motor 2, an electronic control module 3, and a transmission rod 4. The drive crank 1 and the drive motor 2 are both connected to the power input end of the transmission rod 4 to drive the transmission rod 4 to rotate. The power output end of the transmission rod 4 is connected to the height-adjustable desk legs 100 to drive the height-adjustable desk legs 100 to rise and fall. The electronic control module 3 is electrically connected to the drive motor 2.

[0053] The drive handle 1 is used to manually drive the transmission rod 4 to rotate and raise or lower the liftable table leg 100.

[0054] The electrical control module 3 is used to accept user operations and control the drive motor 2 to work according to the user operations, and drive the transmission rod 4 to rotate to raise and lower the liftable table legs 100 by electric means.

[0055] The desk height adjustment control system of this application includes a drive crank 1, a drive motor 2, an electrical control module 3, and a transmission rod 4. Both the drive crank 1 and the drive motor 2 are connected to the power input end of the transmission rod 4 to drive the transmission rod 4 to rotate. The power output end of the transmission rod 4 is connected to the lead screw nut lifting mechanism 101 of one of the height-adjustable desk legs 100 through a reversing gearbox 5 to drive the height-adjustable desk leg 100 to rise and fall. The electrical control module 3 is electrically connected to the drive motor 2. In use, the desk height can be manually adjusted by operating the drive crank 1 to drive the transmission rod 4 to rotate, or the desk height can be automatically adjusted by the electrical control module 3 receiving user operation and controlling the drive motor 2 to work according to the user operation, thereby driving the transmission rod 4 to rotate.

[0056] The height control system of the study desk in this embodiment makes the height control method of the study desk more diverse. Users can choose to control the height of the study desk manually or electrically as needed, which effectively improves the applicability of the study desk.

[0057] It should be noted that the reversing gearbox 5 is also connected to another reversing gearbox (not shown in the figure) via another transmission rod (not shown in the figure), and the other reversing gearbox is connected to the screw nut lifting mechanism (not shown in the figure) of another height-adjustable table leg (not shown in the figure), so that the two height-adjustable table legs 100 of the study table can be raised and lowered synchronously to realize the adjustment of the height of the study table.

[0058] In one embodiment, the electronic control module 3 includes a signal input module 31, a motor controller 32, and a battery 33. The signal input module 31 is connected to the motor controller 32, the battery 33 is connected to the power supply terminal of the motor controller 32, and the drive terminal of the motor controller 32 is connected to the drive motor 2.

[0059] The signal input module 31 is used to accept user operations and output corresponding electrical signals to the motor controller 32 according to the user operations;

[0060] The motor controller 32 is used to output a corresponding control signal to the drive motor 2 according to the electrical signal output by the signal input module 31, so as to control the drive motor 2 to rotate forward, reverse or stop;

[0061] Battery 33 is used to power motor controller 32.

[0062] When a user needs to control the height of the study desk electrically, they can input an operation signal through the operation signal input module 31. The signal input module 31 is used to accept user operations and output corresponding electrical signals to the motor controller 32 according to the user operations. The motor controller 32 outputs corresponding control signals to the drive motor 2 according to the electrical signals output by the signal input module 31 to control the drive motor 2 to rotate forward, reverse, or stop, thereby realizing the height adjustment of the study desk as needed.

[0063] In one embodiment, the signal input module 31 includes a control button 311 and a signal conversion module 312. The control button 311 is connected to the signal input terminal of the signal conversion module 312, and the signal conversion module 312 is connected to the first signal input terminal of the motor controller 32. The signal conversion module 312 is used to convert the input signal of the control button 311 into a corresponding electrical signal and output it to the motor controller 32.

[0064] In this embodiment, by setting control button 311 and signal conversion module 312, when the user needs to control the height of the study desk electrically, the user can input a signal through control button 311. Signal conversion module 312 converts the input signal of control button 311 into a corresponding electrical signal and outputs it to motor controller 32, thereby controlling the drive motor 2 to rotate forward, reverse or stop, so as to realize the height adjustment of the study desk.

[0065] Specifically, the control button 311 may include a raise button, a lower button, and a stop button. When the user presses the raise button, the drive motor 2 rotates forward, driving the transmission rod 4 to rotate forward, causing the height-adjustable table leg 100 to rise. When it reaches the target height, the user can press the stop button, and the drive motor 2 stops rotating. When the user presses the lower button, the drive motor 2 rotates in reverse, driving the transmission rod 4 in reverse, causing the height-adjustable table leg 100 to fall. When it falls to the target height, the user can press the stop button, and the drive motor 2 stops rotating.

[0066] In this embodiment, the study desk can be locally controlled via control button 311.

[0067] In one embodiment, the signal input module 31 further includes a remote controller 313 and a wireless transmission module 314. The remote controller 313 is communicatively connected to the wireless transmission module 314. The signal output terminal of the wireless transmission module 314 is connected to the second signal input terminal of the motor controller 32. The wireless transmission module 314 is used to receive the remote control signal from the remote controller 313 and output the corresponding electrical signal to the motor controller 32 according to the remote control signal.

[0068] In this embodiment, by setting up a remote control 313 and a wireless transmission module 314, when the user needs to control the height adjustment of the study desk electrically, the user can input a signal through the remote control 313. After receiving the input signal from the remote control 313, the wireless transmission module 314 converts the input signal from the remote control 313 into a corresponding electrical signal and outputs it to the motor controller 32, thereby controlling the drive motor 2 to rotate forward, reverse, or stop, thus realizing the height adjustment of the study desk.

[0069] Specifically, the remote control 313 can be equipped with a raise button, a lower button, and a stop button. When the user presses the raise button, the drive motor 2 rotates forward, driving the transmission rod 4 to rotate forward, causing the height-adjustable table leg 100 to rise. When it reaches the target height, the user can press the stop button, and the drive motor 2 stops rotating. When the user presses the lower button, the drive motor 2 rotates in reverse, driving the transmission rod 4 in reverse, causing the height-adjustable table leg 100 to fall. When it falls to the target height, the user can press the stop button, and the drive motor 2 stops rotating.

[0070] In this embodiment, the study desk can be remotely controlled via remote controller 313 and wireless transmission module 314.

[0071] Specifically, in this embodiment, the remote controller 313 is an infrared remote controller, and the wireless transmission module 314 is an infrared receiver. Using infrared for remote control is simple in structure, low in cost, and highly reliable.

[0072] In one embodiment, the study desk height control system further includes a motor control board 6, on which a motor controller 32, control buttons 311, signal conversion module 312, and wireless transmission module 314 are all mounted.

[0073] In this embodiment, by setting up a motor control board 6, and placing the motor controller 32, control button 311, signal conversion module 312 and wireless transmission module 314 on the motor control board 6, the layout and wiring of the circuit system are facilitated.

[0074] Specifically, in this embodiment, the motor control board 6 and the battery 33 are housed inside the drive crank 1, which facilitates the maintenance of the circuit system.

[0075] In one embodiment, the drive handle 1 has a first working position and a second working position.

[0076] When the drive handle 1 is in the first working position, the drive handle 1 is connected to the output shaft 21 of the drive motor 2 so as to drive the output shaft 21 of the drive motor 2 to rotate through the drive handle 1.

[0077] When the drive handle 1 is in the second working position, the drive handle 1 is separated from the output shaft 21 of the drive motor 2 to disconnect the drive connection between the drive handle 1 and the output shaft 21 of the drive motor 2.

[0078] In this way, when it is necessary to manually control the height of the study table, the drive handle 1 is placed in the first working position. At this time, the drive handle 1 is connected to the output shaft 21 of the drive motor 2, so that by rotating the drive handle 1, the output shaft 21 of the drive motor 2 is driven to rotate, thereby realizing the height of the study table.

[0079] When the study desk needs to be raised and lowered electrically, the drive handle 1 is placed in the second working position. At this time, the drive handle 1 is separated from the output shaft 21 of the drive motor 2. The output shaft 21 of the drive motor 2 is then rotated by operating the electronic control module 3 to raise and lower the study desk. Since the drive handle 1 is separated from the output shaft 21 of the drive motor 2 at this time, the drive handle will not rotate under electric control, thus improving operational safety.

[0080] In one embodiment, the study desk height control system further includes a mounting base 7, a first clutch 8, and a second clutch 9, wherein...

[0081] The drive motor 2 is mounted on the mounting base 7, and the end of the output shaft 21 of the drive motor 2 away from the transmission rod 4 is hollow.

[0082] The first clutch element 8 is inserted into the hollow structure of the output shaft 21 of the drive motor 2 and does not rotate relative to the output shaft 21 of the drive motor 2.

[0083] The drive handle 1 is rotatably mounted on the mounting base 7, and the drive handle 1 can slide relative to the mounting base 7 along its own axis of rotation.

[0084] The second clutch 9 is fixedly mounted on the drive crank 1 and extends into the hollow structure of the output shaft 21 of the drive motor 2. The rotation axis of the second clutch 9 coincides with the rotation axis of the drive crank 1. The second clutch 9 can slide freely relative to the first clutch 8 along the direction of its own rotation axis to connect or disconnect with the first clutch 8.

[0085] in,

[0086] When the second clutch 9 is connected to the first clutch 8, the drive handle 1 can drive the output shaft 21 of the drive motor 2 to rotate, so as to drive the transmission rod 4 to rotate manually.

[0087] When the second clutch 9 is disengaged from the first clutch 8, the output shaft 21 of the drive motor 2 can rotate relative to the drive crank 1 to drive the transmission rod 4 to rotate electrically.

[0088] In this embodiment, a first clutch 8 and a second clutch 9 are designed to work together. When the user pushes the drive handle 1 forward, the second clutch 9 disengages from the first clutch 8. At this time, the drive motor 2 can drive the transmission rod 4 connected to it to rotate, thereby realizing electric control of the height adjustment of the table leg 100. When the user pulls the drive handle 1 backward, the second clutch 9 connects to the first clutch 8. At this time, by rotating the drive handle 1, the output shaft 21 of the drive motor 2 and the transmission rod 4 can be driven to rotate, thereby realizing manual control of the height adjustment of the table leg 100.

[0089] In one embodiment, the mounting base 7 is provided with a limiting groove 71, and the driven rocker 1 can be inserted into or disengaged from the limiting groove 71.

[0090] When the drive handle 1 is in the first working position, the drive handle 1 disengages from the limit groove 71;

[0091] When the drive handle 1 is in the second working position, the drive handle 1 is embedded in the limiting groove 71.

[0092] In this embodiment, when the drive handle 1 is pulled back to the first working position, the drive handle 1 disengages from the limiting groove 71. At this time, the second clutch 9 is connected to the first clutch 8. By rotating the drive handle 1, the output shaft 21 of the drive motor 2 and the transmission rod 4 can be driven to rotate, thereby realizing manual control of the lifting of the height-adjustable table leg 100.

[0093] When the drive handle 1 is pushed forward to the second working position, the drive handle 1 is inserted into the limiting groove 71. The limiting groove 71 limits the drive handle 1, preventing it from rotating. At this time, the second clutch 9 separates from the first clutch 8, and the drive motor 2 can drive the transmission rod 4 connected to it to rotate, thereby realizing the electric control of the height of the height-adjustable table leg 100.

[0094] In one embodiment, the first clutch 8 has a through hole 81 and a limiting groove 82, and the second clutch 9 extends through the through hole 81 into the hollow structure of the output shaft 21 of the drive motor 2. The second clutch 9 has a limiting protrusion 91 that matches the limiting groove 82.

[0095] When the drive handle 1 is in the first working position, the limiting protrusion 91 on the second clutch 9 engages with the limiting groove 82 of the first clutch 8.

[0096] When the drive crank 1 is in the second working position, the limiting protrusion 91 on the second clutch 9 separates from the limiting groove 82 of the first clutch 8.

[0097] When the user pushes the drive handle 1 forward and moves it closer to the drive motor 2 along its own rotation axis, the drive handle 1 will cause the limiting protrusion 91 on the second clutch 9 to disengage from the limiting groove 82 of the first clutch 8. In this way, when the output shaft 21 of the drive motor 2 rotates, the output shaft 21 will not drive the drive handle 1 to rotate.

[0098] When the user pulls the drive handle 1 backward along its own rotation axis in a direction away from the drive motor 2, the drive handle 1 will cause the limiting protrusion 91 on the second clutch 9 to be inserted into the limiting groove 82 of the first clutch 8. In this way, when the user rotates the drive handle 1, the output shaft 21 and transmission rod 4 of the drive motor 2 can be rotated by the cooperation of the first clutch 8 and the second clutch 9.

[0099] It is understandable that, in electric control, by reasonably setting the rotation angle of the output shaft 21 of the drive motor 2, such as making the drive motor 2 rotate by an integer multiple of half a turn each time, it can be ensured that the limiting groove 82 and the limiting protrusion 91 are always aligned.
