[0031] Warning signs are devices used to display warning information in order to convey various corresponding signals to the outside world.

[0032] For example, some mechanical processing production environments often involve the use of process electrical equipment, necessitating the deployment of high-voltage switchgear. While there are comprehensive regulations for the operation of high-voltage switchgear, they cannot completely eliminate equipment and personal accidents caused by operational errors. Furthermore, indicating the operating status of high-voltage switchgear is a critical safeguard against misoperation. However, current tagging systems rely primarily on manual tagging by operators, which is prone to errors, omissions, and misplaced tags, leading to accidents caused by misoperation.

[0033] In view of this, an electronic sign warning device is proposed in the present application. The aforementioned electronic sign warning device can display multiple signals, thereby having high flexibility of use.

[0034] See Figures 1 to 6 Generally speaking, the electronic sign warning device includes a back panel 101, a housing 102, a power supply and a display component, such as Figure 1 shown.

[0035] The back plate is a thin plate structure with thickness. Therefore, in order to facilitate the positioning discussion of other structures in the device, the front and back sides along the thickness direction can be defined in the back plate.

[0036] The backplate can be flat or curved. Different backplate configurations can adapt to different attachments, facilitating and speeding installation. Furthermore, the backplate can be made of different materials to facilitate installation in various scenarios.

[0037] Furthermore, a replaceable fixing mechanism is provided on the back of the back plate. As the name implies, the fixing mechanism is used to connect to the object to which the warning device is attached. For example, the object to be attached is the high-voltage switchgear mentioned above, or an abandoned building, etc.

[0038] Depending on the specific type and shape of the object being attached, the fixing mechanism can be designed in different structural forms. Furthermore, to facilitate the implementation of different connection methods, a magnet can be fixed to the back of the back plate, thereby magnetically connecting the fixing mechanism to the back plate. Therefore, it can be understood that the fixing mechanism has a structure made of a ferromagnetic material, such as an iron sheet.

[0039] Alternatively, in another example, the fixing mechanism can be configured to be fixedly connected to the backplate, and the fixing mechanism can be designed to include two parts. One part is responsible for the fixed connection to the backplate, while the other part is designed to have multiple replaceable structures. In other words, the two parts of the fixing mechanism have a universal connection configuration. By designing the fixing mechanism as two parts, the other part can be replaced as needed to meet the requirements of different connection methods. Utilizing this design approach, the electronic sign warning device can be used in a variety of situations.

[0040] In a specific embodiment, the fixing mechanism may include a base 1031 and a connecting member 1032, such as Figure 4 、 Figure 5 and Figure 6 As shown, the base is the part of the fixing mechanism that is fixedly connected to the back plate. The fixed connection can be welding, interference fit connection, or bonding. The connecting piece can be a part of the fixing mechanism that is replaceable.

[0041] Taking into account the need to connect with different attachments, the number of connectors in the fixing mechanism can be selected to be different, for example, at least two, an even number, or an odd number; in specific embodiments, the connectors can be three, four, five or six, etc.

[0042] As can be seen, the base and the connector are detachably connected. And illustratively, the base and the connector can be threaded or snap-fitted. Different connection methods are achieved through the connector, and accordingly, each connector has a different connection method with the attached object.

[0043] For example, if the connector and the object to be attached are bonded, the connector can be a plastic plate or a metal plate with adhesive applied to the surface. Alternatively, in some cases, the connector may be required to be attached to a surface of a special structure, so a flexible connector, such as an adhesive tape, with adhesive applied to the surface may be required.

[0044] Alternatively, the connection between the connecting member and the attached object is magnetic, and the connecting member can be configured as a magnetic material, or a magnet embedded in the aforementioned plastic plate, metal plate or tape.

[0045] Alternatively, the connector and the object to be attached are connected by snap-fit. Figure 5 and Figure 6 , then the connector can

[0046] It is a clamping member with a notch. For example, the connecting member is a U-shaped clamp 1033; another connecting member 203 is a C-shaped clamp 2033, and has certain expansion and contraction properties. In this way, when connecting, the object to be attached can enter the clamp through the notch.

[0047] In some examples of the present invention, a connecting member is a clamping member, and the clamping member includes a fixed plate, a transverse plate, and a movable plate. The fixed plate, transverse plate, and movable plate cooperate to form the clamping member, forming a U-shaped clamp. The fixed plate is fixedly connected to one end of the transverse plate, and the movable plate is hinged to the other end of the transverse plate via a rotating shaft and a torsion spring. Therefore, the movable plate can be pressed against the object to be attached through the rotation of the movable plate about the rotating shaft and the force of the torsion spring.

[0048] Now let's turn to the housing. As the name suggests, the housing is a structure with an internal space that can accommodate various appropriate structures in the electronic sign warning device. The housing can be made of the same material as the backplate, or it can be made of a different material.

[0049] In order to facilitate installation of various purposefully selected structures in the inner space of the housing, the housing is designed as two parts, which can be fixed by studs or bolts, and the two parts of the housing can be disassembled when necessary.

[0050] The connection method between the housing and the back plate is, for example, that the housing is fixed to the front surface of the back plate. In addition, the housing is provided with an internal cavity 1021 as the internal space mentioned above. Considering the installation of various structures in the internal cavity of the housing, threaded holes can be provided on the inner wall of the housing, grooves can be provided on the inner wall of the housing, and stop walls, locking walls, etc. can be provided on the inner wall of the housing.

[0051] Furthermore, in order to set the display component on the shell, the shell can be provided with an opening, or a hole can be provided in the shell, and the display component can transmit signals using the circuit passing through the hole. In particular, a telescopic structure is provided in the shell, which can retract and retract the display screen to the interior chamber to protect it from rain, water mist, etc. At the same time, when the weather improves, the display screen can be extended to extend out of the interior chamber. For example, this can be achieved using a track, a spring, and an electromagnet. The track is fixed in the shell, and one end of the spring is connected to the display screen and the other end is connected to the electromagnet. When the electromagnet is attracted, the spring shortens along the track, allowing the display screen to be retracted into the shell. When the electromagnet releases the spring, the spring shortens along the track, pushing the display screen out of the shell.

[0052] For example, the power supply is disposed in the inner chamber of the housing. In different examples, the power supply is configured as different instances according to different situations, such as a primary battery or a secondary battery. Alternatively, the power supply can be designed as a power adapter. The power adapter can be connected to the mains power and convert the mains power into electrical parameters such as power, voltage, or current required by the corresponding electrical device.

[0053] On this basis, a two-part display assembly comprises a display screen 103 and a control panel. The display screen is fixed to the surface of the housing, exposing the display surface so that the user can view the displayed warning information. The display is also electrically connected to a power source via a cable passing through the housing. In contrast, the control panel in the display assembly is disposed within the content chamber and electrically connected to the power source. Furthermore, the control panel is configured to control the content displayed on the display screen.

[0054] The control board can be a collection or combination of various electronic circuits and components. For example, the control board can be a single chip microcomputer, a microcontroller, a programmable logic controller, etc. The control board can adopt various conventional devices in the prior art, which will not be elaborated in detail in this application. Therefore, the single chip microcomputer can be connected to a power supply and also to a display, such as Figure 2 shown.

[0055] The display can be a display screen such as OLED or LCD. Alternatively, the display can be a black and white display screen, or a color display screen. Furthermore, the control panel can also have a photosensor, and use the photosensor to control the display brightness of the display screen to reduce energy consumption and reduce heat. Or further, the control panel can also have a timing module, which controls the brightness of the display, as well as turning it on and off at different times by formulating different time curves. In this way, through the combined use of the timing module and the photosensor, and the cooperation of the control panel, a more flexible display effect can be achieved, as well as more energy saving, increased service life, reduced heat generation, etc.

[0056] In addition to being able to display warning information, in the improved solution, the electronic sign warning device can also include a sound alarm. The sound alarm is fixed to the inner chamber of the shell, and the sound alarm is also connected to the control panel. In this way, the control panel can also play sound information when controlling the display to display the warning information. Then, in some special occasions, the information displayed on the display screen can also be played through the sound alarm through the sound alarm information. For example, in the case where the electronic sign warning device is used in situations where the strength is poor or it is inconvenient to view directly, the sound alarm can improve the prompt effect through audio playback. The sound alarm is a speaker.

[0057] In addition to the aforementioned improvements, a wireless transmitter module and / or a Bluetooth module can also be configured within the control board. These modules are connected to the control board (or its printed circuit board) via soldering or bonding. These modules can transmit wireless signals, enabling customization and design of display content, the display signal, and the sound signal of the audible alarm to meet diverse warning requirements. Furthermore, these warning messages can be pre-set in the control board's memory or customized on-site at different times as needed.

[0058] The customized or preset method can be transmitted via the interface 1022 (such as a USB interface) on the control panel, see Figure 3 Alternatively, the electronic sign warning device may further include a control terminal wirelessly connected to the wireless transmitter module. The control terminal can facilitate the operator to leave the site and improve the convenience of operation.
