Description

This invention relates to a human-machine interface, and in particular to a human-machine interface device for use in an AC/DC power supply device or control device.

With the advent of industrial automation, human-machine interfaces (HMI) are widely used in many devices. A human-machine interface is also called an operator interface (OI), and its main function is to provide an interface between people and machines, and to communicate system processes or settings using letters, numbers, or graphics. Its purpose is to display messages such as alarms, locks, and other related information.

A human-machine interface allows a device to be operated using a combination of buttons and switches with different colors, sizes, and appearances, as well as indicator lights, as well as displaying operating status. For example, in addition to turning the power on and off, a display device (Flat Panel Display: FPD) can be used to inform the operator of the status of the equipment, or to convey messages for the operator's reference. Ta. Liquid crystal displays (LCDs) are currently the mainstream type of display device in general use, and it is common to integrate the above-mentioned buttons, switches, indicator lamps, or display devices to construct a human-machine interface module. Ta.

When a human-machine interface is used in a device with a smaller panel area, such as a one-rack-unit (1U) AC/DC power supply device or control device, the usable area of the human-machine interface is reduced, especially when maximizing the area of the air intake. Therefore, when designing a display device for the human-machine interface, it is difficult to clearly display, easily read, and increase visibility within the limited small screen area.

Please refer to Figure 1. Figure 1 is an exploded perspective view showing a human-machine interface device of an AC/DC power supply device or control device according to one embodiment of the present invention.

As shown in FIG. 1, a human-machine interface device for an AC/DC power supply device or a control device according to an embodiment of the present invention includes a human-machine interface module 10 and a face membrane 20.

The human-machine interface module 10 is fixedly installed on a panel of an AC/DC power supply device or a control device. A rectangular liquid crystal screen 11 is provided on the front side of the human-machine interface module 10. The liquid crystal screen 11 is composed of a certain number of pixels that can emit light. The human-machine interface module 10 is provided with a plurality of buttons 12 and a plurality of knobs 13 on one side of the liquid crystal screen 11 so that a user can operate the human-machine interface.

The surface membrane 20 is a plastic film located on the front side of the human-machine interface module 10, has a rectangular shape, and is pasted on the panel of the AC/DC power supply device or the control device. The surface film 20 corresponds to the transparent window 21 that the liquid crystal screen 11 has, and positions the liquid crystal screen 11 on the window 21. A status display area 22 adjacent to the window 21 is provided outside the surface membrane 20. The status display area 22 of this embodiment is located on one side of the window 21 in the vertical direction, and has the same color as the liquid crystal screen 11, so it looks like a part of the liquid crystal screen 11. Different status messages can be displayed within the status display area 22. A plurality of status messages are arranged vertically and inform the user of the current status of the reading device. The multiple status messages of this embodiment may include statuses such as CV (constant voltage), CC (constant current), CP (constant power), ERR (failure), REM (remote control), and lock code (lock). good. The face membrane 20 has a plurality of elongated holes 23 and a plurality of circular holes 24 corresponding to the shapes of the plurality of buttons 12 and the plurality of knobs 13.

In order to better understand the structural features of this invention, the technical means of its operation, and the effects it is expected to achieve, the principle of its operation will be explained below, which we believe will provide a deeper and more concrete understanding of the invention.

See Figure 2. FIG. 2 is a perspective view showing a state in which a human-machine interface device of an AC/DC power supply device or a control device according to an embodiment of the present invention is attached to a power supply device.

As shown in FIG. 2, when the human-machine interface module 10 is mounted on the panel 201 of the AC/DC power supply device 200, the liquid crystal screen 11 is exposed from the front side of the panel 201, and the surface film 20 is pasted on the panel 201, the surface film Twenty windows 21 correspond to the positions of the liquid crystal screen 11. The positions of the plurality of elongated holes 23 and the plurality of circular holes 24 correspond to the positions of the plurality of buttons 12 and the plurality of knobs 13. In this way, the human-machine interface device of the AC/DC power supply device or the control device according to this embodiment can be installed on the panel 201 of the AC/DC power supply device 200.

See Figure 3. FIG. 3 is an explanatory diagram when setting the human-machine interface device of the AC/DC power supply device or the control device to a constant voltage according to an embodiment of the present invention.

As shown in FIG. 3, when the user sets the AC/DC power supply device 200 to a constant voltage state, the user operates the button 12 or knob 13 to operate the screen of the LCD screen 11, causing the light spot 111 in the status display area 22 adjacent to the LCD screen 11 to emit light at a location corresponding to the CV (constant voltage) status message. The light spot 111 is a circular light-emitting spot made up of multiple pixels, and since the light spot 111 has a large light-emitting area and brightness, the user can quickly read the current constant voltage (CV) status message from the position of the light spot 111.

See Figure 4. FIG. 4 is an explanatory diagram when setting the human-machine interface device of the AC/DC power supply device or control device to constant current according to an embodiment of the present invention.

As shown in FIG. 4, when the user changes the setting of the AC/DC power supply device to a constant current state, he or she similarly operates the button 12 or knob 13 to operate the screen of the LCD screen 11, and causes the light spot 112 in the status display area 22 adjacent to the LCD screen 11 to light up and display the CC (constant current) status message. The light spot 112 is also composed of multiple pixels, and at this time the user can quickly read the current constant current (CC) status message from the position of the light spot 112.

If the user selects remote control or lock, the LCD screen 11 similarly displays a light point, allowing the user to read the current REM (remote control) or lock status message. In addition, if the device breaks down, a light point is displayed, allowing the user to read the current ERR (failure) status message, allowing the user to quickly deal with the failure.

As can be seen from the above description, the human-machine interface device of the AC/DC power supply device or control device according to the present invention integrates the display screen, buttons, knobs, etc. in the human-machine interface with the human-machine interface module, and displays the status. With a design that corresponds areas to light spots, the LCD screen saves pixels used by status messages and allows more pixels to be provided to display numerical and other data such as voltage, current, etc. Because of its use, it can be displayed clearly even in a limited screen area, making it easy to read and improving visibility.

To summarize the above, this invention has a high degree of inventiveness and practicality among products of the same type, and even when we searched domestic and foreign technical documents, we did not find a similar structure in the literature, and it is difficult to register as a utility model. In order to meet the requirements, we hereby apply for utility model registration in accordance with the law.

The above is merely a preferred embodiment of the present invention, and although the preferred embodiment of the present invention has been disclosed as above, it is in no way intended to limit the present invention. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Therefore, the scope of the utility model registration claims of the present invention should be broadly interpreted to include such changes and modifications.
