[0031] See Figures 1-5 In one embodiment, a controller for an electric height-adjustable desk includes a housing 1, a control board 2 disposed within the housing 1, and a touch display module 3 disposed on the housing 1. The touch display module 3 is electrically connected to the control board 2. The touch display module 3 includes a display screen 31, a touch control screen 32 attached to the surface of the display screen 31, and a glass cover plate 33 attached to the surface of the touch control screen 32. The touch control screen 32 includes a screen touch unit 321 that is consistent with the display area of ​​the display screen 31, and a plurality of capacitive touch buttons located on the side of the screen touch unit 321. The screen touch unit 321 and the capacitive touch buttons are both electrically connected to the control board 2.

[0032] Specifically, the capacitive touch buttons and the screen touch unit 321 are integrated on a single glass panel, and signal conflicts are avoided through a time-division driving algorithm.

[0033] Furthermore, the control board 2 is equipped with a system-on-a-chip (SOC) and a motor drive MCU, which is the core computing unit. It has a built-in CPU, memory and other interfaces to perform display driving, sensor signal acquisition, human presence algorithm calculation, interaction and settings, and finally output control commands to the motor drive MCU. The motor drive MCU performs linear motor driving, processes Hall signals, outputs voltage and current, and monitors voltage and current changes to determine the table's up and down movement.

[0034] Specifically, the capacitive touch buttons include an up button 322 and a down button 323. The up button 322 and the down button 323 are used to control the raising and lowering of the electric height-adjustable desk, respectively. The desktop can be raised and lowered by touching the up button 322 and the down button 323, which is time-saving, labor-saving and convenient.

[0035] Furthermore, a speaker 5 is provided on the side of the housing 1. The speaker 5 is electrically connected to the control board 2. Specifically, the speaker 5 is used for sound prompts and is connected to the SOC.

[0036] It is understandable that a power button 6 is provided on the side of the housing 1, and the power button 6 is electrically connected to the control board 2.

[0037] The housing 1 includes a bottom shell 11 connected to the lifting table and a side shell 12 for supporting the touch display module 3. The bottom shell 11 is provided with bolt holes 111 for connecting to the lifting table. The display screen 31 of the touch display module 3 on the side shell 12 is obliquely upward, so as to facilitate better operation by the user and is more in line with ergonomics.

[0038] The display screen 31 is an LCD display screen 31. Specifically, the display screen 31 is 2.0 inches in size, with a resolution of 320x172 and a brightness of 300cd.

[0039] The ITO layer in the touch control screen 32 uses self-capacitive diamond-shaped electrodes with a spacing of ≤1mm, preferably 0.5mm to 1mm, to ensure the touch accuracy and stability of the touch control screen 32.

[0040] Furthermore, the surface of the glass cover 33 is provided with an anti-fingerprint coating structure, which reduces fingerprint smudges and makes it more convenient and reliable to use.

[0041] The housing 1 is provided with a power interface 7 and a control interface 8 that are connected to the control board 2. The control interface 8 is electrically connected to the drive motor in the electric lifting table.

[0042] The specific working process and principle of this utility model:

[0043] When in use, connect the controller's power interface 7 to the power supply, connect the control interface 8 to the drive motor of the electric lifting table, start the controller through the power button 6, and operate the up button 322 and down button 323 to directly drive the electric lifting table to rise and fall.

[0044] The display screen 31 can show the lifting status of the electric height-adjustable desk, sitting time, prolonged sitting reminder, prompt tone volume, lock status, position memory, self-test faults, and error messages. Compared with existing controllers, the displayed information is more comprehensive. By directly touching the display screen 31, users can further view and set the information on the display screen 31. Multiple functions can be achieved through touch operation. The housing 1 is equipped with a speaker 5 that is electrically connected to the control board 2. The speaker 5 emits prompt tones to improve the interactive effect of the operator's operation of the touch control screen 32. The speaker 5 also reminds the operator of the operation and use, and provides prompts for prolonged sitting reminders, self-test faults, and error messages.

[0045] The desktop can be raised and lowered by touching the up button 322 and down button 323, which is more time-saving and labor-saving than physical button operation. Through the touch screen 31, various information can be set and viewed. The combination of capacitive touch buttons and screen touch unit 321 makes the high-frequency lifting operation of the controller convenient and quick to use. The touch screen 31 makes the controller's function settings more diverse and meets the multi-functional needs of electric height-adjustable desks.

[0046] The display screen 31 displays various information such as lifting status, sitting time, prolonged sitting reminder, prompt tone volume, lock status, position memory, self-test faults, and error messages. The speaker 5 emits prompt tones. Through the combination of the display screen 31 and the speaker 5, the content displayed on the display screen 31 is richer, and the interaction between the controller and the user is improved.

[0047] In one embodiment, a passive infrared sensor 4 (PIR sensor) for detecting the presence of a human body is provided on the side of the housing 1. The passive infrared sensor 4 is electrically connected to the control board 2. Specifically, the passive infrared sensor 4 is used to sense changes such as the user's approach and departure, and transmits them to the SOC on the control board 2.

[0048] The touch screen 31 allows users to set different standing and sitting heights to suit various user needs. The touch screen 31 also allows users to set sitting and standing times, providing reminders and adjusting the height accordingly when different durations are reached. Three reminder modes are available: the first mode uses the display screen 31 for reminders; the second mode uses both the display screen 31 and speaker 5 for reminders, with adjustable volume and sound effects for speaker 5; and the third mode automatically triggers the drive motor, causing the desktop to automatically rise or fall after prolonged sitting.

[0049] Specifically, when a user sits down near the passive infrared sensor 4, the passive infrared sensor 4 sends a command to the SOC on the control board 2. The control board 2 starts timing and displays the sitting time on the display screen 31. When the sitting time exceeds the limit, the system can provide feedback to the user in three modes through the settings program, in order to remind the user of prolonged sitting. Specifically, in the first mode, the display screen 31 reminds the user "You have been sitting for several hours (minutes), remind you to stand for several hours (minutes)," and provides suggestions for sitting and standing time. In the second mode, the display screen 31 and the speaker 5 simultaneously broadcast a message to the user. The system offers several modes. First, it provides a sedentary reminder. Upon receiving the reminder, the user can raise or lower the desktop using the touch controls 322 (up) and 323 (down) to prevent prolonged sitting. Second, it uses a control panel 2 to control the drive motor, thereby raising and lowering the desktop and directly intervening in the user's sedentary behavior. The passive infrared sensor 4 tracks the user's sitting time. This system not only prevents prolonged sitting through reminders but also intervenes by directly controlling the drive motor to raise and lower the desktop, achieving automatic desktop raising and lowering. This is more beneficial to the user's health and further meets their multi-functional needs.

[0050] It is important to note that when the user leaves their seat, the passive infrared sensor 4 does not detect the user's presence, and the seat timer is cleared until the user sits down again, at which point the timer restarts. When the user actively raises the table, the passive infrared sensor 4 also clears the timer to improve the controller's versatility. In this solution, the controller for the height-adjustable desk, through the setting of the passive infrared sensor 4, eliminates the need for manual timing and manual operation of the desk, thus achieving the functions of long-term seat reminders and automatic height adjustment, making the desk more intelligent and easier to use.

[0051] The control panel 2 supports voice interaction. The above functions can be operated through the touch screen 31 with the guidance of the voice assistant. The speaker 5 plays voice prompts to help the user complete the settings.

[0052] The signal conflict between the capacitive touch button and the screen touch unit 321 is avoided by using a time-sharing driving algorithm, which is an existing technology. The control board 2 is equipped with an obstruction detection and back-off anti-pinch function, which is common knowledge to those skilled in the art and will not be described in detail here.

[0053] A passive infrared sensor (PIR sensor) is an electronic component capable of detecting infrared radiation emitted from objects within its field of view, primarily used for detecting the movement of objects, animals, and humans. This type of sensor does not radiate energy in any form, hence it is called a "passive" sensor. Passive infrared sensors are existing technology and will not be described in detail here.

[0054] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
