[0002] Currently, elevator control panels include contactless sensor buttons and contact mechanical buttons. Contact mechanical buttons have a limited lifespan. Contactless sensor buttons are not user-friendly for visually impaired individuals, as they require touch to read the text on the button. When a hand approaches the button, it is interpreted as a trigger, causing the current floor to be pressed, resulting in false triggering. Utility Model Content

[0031] Many electronic devices use display panels to present content to users. Display panels can be pixel-based, such as light-emitting diode (LED) panels, organic light-emitting diode (OLED) panels, and / or plasma panels. In many electronic devices, such as elevators, pixel-based display panels are commonly used to display content and / or provide a user interface.
[0032] In some embodiments, this application provides an electronic device, such as an elevator, which includes an elevator body and a control component connected to the elevator body. The elevator body includes a car, etc., and the control component is the main interface for users to operate the elevator body. Its main purpose is to control the elevator body to transport users to the target floor. The control component includes an elevator control panel.
[0033] like Figure 1 As shown, in some embodiments, the control components include a display 10, an interface 20, and an input structure 30.
[0034] In some embodiments, the display 10 may be a liquid crystal display (LCD) 10, which allows a user to view images generated on an electronic device, for example, displaying the current floor number, such as "10," in the upper area of the top surface of the display 10, indicating that the user is currently on the 10th floor. In some embodiments, the display 10 may include a touchscreen, which allows a user to interact with the user interface of the electronic device. Furthermore, it should be understood that in some embodiments, the display 10 includes one or more organic light-emitting diode (OLED) displays 10, or some combination of a liquid crystal display (LCD) panel and an OLED panel. The display 10 can set the button's operating mode (including mechanical button operating mode, sensor button operating mode, and adaptive operating mode) through a screen settings menu. When using the adaptive operating mode, the default state is sensor button operating mode; when an external signal input is detected, the sensor button operating mode is automatically turned off, and the mechanical button operating mode is turned on. Operating the buttons can control the elevator body to transport the user to the target floor.
[0035] The input structure 30 includes mechanical buttons and sensor buttons, corresponding to the mechanical button working mode and sensor button working mode mentioned above. The input structure 30 enables the user to interact with the electronic device 10 (for example, pressing the number key in the mechanical button can control the elevator body to transport the user to the corresponding floor).
[0036] like Figure 3As shown, in some embodiments, the input structure 30 includes a dual-mode button circuit board 301, a button actuator 302, and a button 303. The dual-mode button circuit board 301 controls the mechanical button operating mode and the inductive button operating mode. The top surface of the dual-mode button circuit board 301 is copper-clad as the sensing plate of the touch chip. Four vertically arranged button springs 304 (as electrical elastic connectors) are mounted on the top surface of the dual-mode button circuit board 301. The top surface of the dual-mode button circuit board 301 has four corners, and each button spring 304 is located on the top surface of the dual-mode button circuit board 301 and near a corner. The electrical elastic connector passes through the hollow area of the button actuator 302. In some embodiments, the specifications of the button springs 304 are as follows: The effective number of turns is 9. The button actuator 302 is annular and mounted on the top surface of the dual-mode button circuit board 301. The button actuator 302 has an internal circumferentially flat portion extending from the inner wall towards the center. The top surface of the circumferentially flat portion is lower than the overall top surface height of the button actuator 302. The circumferentially flat portion forms a hollow area of the button actuator 302, and this hollow area faces the top surface of the dual-mode button circuit board 301. In some embodiments, the button actuator 302 is made of polycarbonate material. The sensing part 307 is sheet-shaped and mounted on the top surface of the circumferentially flat portion of the button actuator 302. The sensing part 307 covers the hollow area of the button actuator 302, and its bottom surface is connected to the upper end of the button spring 304. In some embodiments, the sensing part 307 includes a copper foil sheet. The button 303 is mounted on the top surface of the button actuator 302; in some embodiments, the button 303 includes a support portion and a reaction portion located on the top surface of the support portion. The support portion is sheet-shaped and has a shape that is substantially the same as that of the button actuator 302, while the reaction portion has a circular cross-section. The support portion of the button 303 is mounted on the top surface of the sensing portion 307; in some embodiments, the button 303 includes a PMMA button 303.
[0037] (1) Working principle of the induction button working mode
[0038] like Figure 4 and Figure 3 As shown, the inductive button operates on a capacitive non-contact sensing principle. The copper plating on the front of the dual-mode button circuit board 301 serves as the sensing plate of the touch chip, tightly connected to the sensing part 307 via the button spring 304, acting as one electrode of the capacitor plate. The finger acts as the other electrode. When a finger approaches the button 303, according to the following formula, the distance between the capacitor plates decreases, and the capacitance value is inversely proportional to the distance between the plates, thus increasing. The touch chip detects this capacitance change, and when it reaches a set threshold, it determines that an object is approaching and outputs a button press signal.
[0039] C=εS / 4πkd
[0040] Where: ε (dielectric constant) represents the dielectric properties of the dielectric material; S (area of the capacitor plates facing each other) represents the area of the two parallel plates facing each other; d (distance between the capacitor plates) represents the distance between the two parallel plates; k (electrostatic constant) represents a fixed value, k = 9 × 10⁻⁶. 9 Nm² / C².
[0041] The dual-mode button circuit board 301 is a PCB with copper plating on the front. When U1 detects that the capacitance on the sensing plate is greater than the threshold, OUT1 outputs a high level, and Q1 is reversed and SI- outputs a low level.
[0042] (2) Working principle of mechanical button working mode
[0043] like Figure 5 and Figure 3 As shown, the mechanical button is designed on the front of the dual-mode button circuit board 301. When a finger presses the button 303, the downward force deforms through the button spring 304, and the button actuator 302 presses the SW1 button on the circuit board, causing SW1 to close. BUT_DEU outputs a low level, indicating that a button has been pressed.
[0044] (3) Input of dual-mode button
[0045] like Figure 6 Hehe Figure 3 The dual-mode button differs from the ordinary single-mode button in that it has two output signals: a sensor output signal and a mechanical button output signal. The dual-mode button circuit board 301 and the elevator control system read the corresponding signal as the current button state based on the current button mode.
[0046] In some embodiments, the input structure 30 further includes a button housing 305, which circumferentially covers the outer wall of the button actuator 302, the sensing part 307, and the support part of the button 303. The bottom corner area of the button housing 305 has screw holes. The button housing 305 is mounted on the top surface of the dual-mode button circuit board 301 by engaging with the screw holes using cross-head self-tapping screws 306. The cross-head self-tapping screws 306 are located on the top surface of the dual-mode button circuit board 301.
[0047] like Figure 2As shown, interface 20 is an external input interface detection circuit that supports 5V / 24V input. The port is designed with TVS anti-electrostatic interference and uses optocoupler isolation, ensuring complete electrical isolation between the input and output terminals, resulting in strong anti-interference capabilities and stable operation. This interface 20 is electrically connected to both the elevator control system and the input structure 30. When the button operating mode is set to adaptive operating mode, the elevator control system will activate / deactivate the inductive button operating mode based on the signal from interface 20. When there is no input signal, the elevator control system activates the inductive button operating mode; when there is an input signal, the elevator control system deactivates the inductive button operating mode and activates the mechanical button operating mode.
[0048] The elevator control panel is designed to be accessible to people with disabilities. Under normal circumstances, it uses touch-sensitive buttons, which greatly extend the lifespan of the buttons because there is no wear and tear from mechanical movement. When special needs passengers use the elevator, mechanical buttons are used to meet the needs of a wider range of people.
[0049] People with disabilities can conveniently ride elevators by using this control component (e.g., the elevator control panel). Under normal circumstances, the sensor-operated button mode significantly extends the button's lifespan due to the absence of mechanical contact wear. When special needs passengers are using the elevator, the mechanical button mode is used to meet the needs of a wider range of people.
[0050] The foregoing is merely intended to illustrate the principles of this utility model.
