[0015] By covering a flame-retardant layer above the imaging layer, in the event of high-temperature situations such as a fire, the flame-retardant layer can effectively block external fire sources from directly contacting the imaging layer and the substrate, playing a preliminary fire-prevention role; at the same time, by designing the connection layer, on the one hand, both sides of the connection layer have adhesiveness, thus bonding the flame-retardant layer and the imaging layer, and on the other hand, the connection layer also has a flame-retardant effect. On the premise of the preliminary fire prevention of the flame-retardant layer, the connection layer further prevents the spread of fire. Under the dual fire-prevention effects of the connection layer and the flame-retardant layer, the flame-retardant effect on the display module is greatly improved; moreover, the structural design of the magnetic part of the display module enables it to be fixed to the chassis by magnetic attraction.

[0035] As Figures 1 - 3As shown in the figure, the present utility model provides a display mechanism 1 with a flame retardant function, which is used to be fixed to the chassis 2 of a display device. The display mechanism 1 with a flame retardant function includes: a display module 11, a flame retardant layer 12, and a connection layer 13. The display module 11 is used to display relevant information to the outside world. The flame retardant layer 12 is used to prevent the spread of fire to the display module 11. The connection layer 13 is used to connect the display module 11 and the flame retardant layer 12.

[0036] The display module 11 includes a substrate 111, an imaging layer 112, and a magnetic member 113. The imaging layer 112 is disposed on one side of the substrate 111, and a plurality of magnetic members 113 are uniformly disposed on the other side of the substrate 111. The substrate 111 is magnetically attracted to the chassis 2 through the magnetic members 113. The flame retardant layer 12 covers the imaging layer 112. The connection layer 13 is used to connect the imaging layer 112 and the flame retardant layer 12, and the connection layer 13 is located between the imaging layer 112 and the flame retardant layer 12.

[0037] By designing that the magnetic member 113 is magnetically attracted to the chassis 2, that is, the fixed installation method of the display module 11 and the chassis 2 adopts a magnetic attraction method, rapid connection and disconnection are realized. On the one hand, the magnetic attraction method is convenient for installation and disassembly; on the other hand, in case of a fire, the display module 11 and the chassis 2 can be quickly disconnected, realizing the physical isolation of the display module 11 and the chassis 2. Whether the display module 11 catches fire or the chassis 2 catches fire, they can be isolated in time to prevent the spread of fire. It should be noted that the specific number of the magnetic members 113 should be designed according to the actual use size requirements.

[0038] By covering a layer of flame retardant layer 12 above the imaging layer 112, it can effectively block the direct contact of external fire sources with the imaging layer 112, playing a preliminary fire prevention role; and, by adopting the connection layer 13, since the connection layer 13 has adhesiveness, the flame retardant layer 12 and the imaging layer 112 are bonded together, and at the same time the connection layer 13 has a flame retardant effect. On the premise of the preliminary fire prevention of the flame retardant layer 12, it further prevents the spread of fire. Thus, under the dual flame retardant effects of the flame retardant layer 12 and the connection layer 13, the flame retardant effect on the display module 11 is greatly improved.

[0039] Exemplarily, the display module 11 is an LED display module. The imaging layer 112 is a layer composed of a plurality of lamp beads, and the thickness of the lamp bead layer is 1 millimeter. The substrate 111 is, for example, a PCB board, and the thickness range of the PCB board is 1 millimeter to 2 millimeters.

[0040] As Figure 1 and Figure 2As shown, in some embodiments of the present utility model, the display module 11 further includes an adhesive layer. The adhesive layer is disposed on the surface of the imaging layer 112. That is, the imaging layer 112 is covered with the adhesive layer on its surface, so that the imaging layer 112 is close to a smooth plane. The connection layer 13 covers the surface of the adhesive layer, and the flame retardant layer 12 covers the surface of the connection layer 13. In this embodiment, the display module 11 adopts the GOB process packaging technology. It should be understood that the GOB (Glue On Board) process is a packaging technology that directly covers the glue on the LED module circuit board. The glue layer evenly covers the circuit board and the LED chips, playing a role in protection and packaging. Due to the existence of the glue layer, the surface of the LED module using the GOB process is flatter, and the reflection and scattering of light are more uniform, thereby improving the contrast and clarity of the display screen. For example, the glue used is a special optical heat-conducting nano-filling material.

[0041] As Figure 1 and Figure 2 shown, in some embodiments of the present utility model, the flame retardant layer 12 is a transparent flame retardant layer. Exemplarily, the flame retardant layer 12 is transparent glass.

[0042] As Figure 1 and Figure 2 shown, in some embodiments of the present utility model, the connection layer 13 is a transparent adhesive layer. Exemplarily, the material of the connection layer 13 is flame retardant silica gel or flame retardant polyurethane glue or flame retardant acrylic glue, which can not only effectively connect the flame retardant layer 12 and the adhesive layer of the display module 11, but also effectively prevent the spread of fire when on fire, achieving the effect of secondary flame retardancy.

[0043] As Figure 1 and Figure 2 shown, in some embodiments of the present utility model, the thickness range of the flame retardant layer 12 is from 3 millimeters to 8 millimeters. In this embodiment, designing a flame retardant layer 12 with a thickness of 3 millimeters to 8 millimeters can achieve a good flame retardant effect.

[0044] As Figure 1 and Figure 2 shown, in some embodiments of the present utility model, the thickness range of the connection layer 13 is from 0.5 millimeters to 1 millimeter. In this embodiment, designing a connection layer 13 with a thickness of 0.5 millimeters to 1 millimeter can not only bond the adhesive layer of the display module 11 and the flame retardant layer 12 together, but also achieve a good secondary flame retardant effect.

[0045] As Figure 3 shown, the present utility model also provides a display device, including: the display mechanism 1 with a flame retardant function as described above. It should be noted that the specific number of the display mechanisms 1 with a flame retardant function should be specifically designed according to the actual required size.

[0046] As Figure 2 andFigure 3 As shown, in some embodiments of the present invention, the display device further includes: a chassis 2. It should be noted that, Figure 3 The display device shown only illustrates one display mechanism 1 with a flame retardant function. The display mechanism 1 with a flame retardant function should be adaptively adjusted according to the size of the chassis 2. Other display mechanisms 1 with a flame retardant function are omitted.

[0047] The chassis 2 is equipped with a controller 22 and a number of electromagnets 21 corresponding to the magnetic elements 113. For example, if there are eight magnetic elements 113, there will also be eight corresponding electromagnets 21. A temperature sensor 23 is used to monitor the temperature of the display module 11. For example, the temperature sensor 23 is located on the back of the substrate 111 to accurately monitor the temperature of the display module 11. Both the electromagnets 21 and the temperature sensor 23 are connected to the controller 22.

[0048] The temperature sensor 23 transmits the monitored temperature signal to the controller 22, and the controller 22 controls the polarity of the electromagnet 21 according to the temperature signal, thereby achieving mutual attraction or repulsion between the electromagnet 21 and the magnetic part 113. If the display module 11 reaches a high temperature, that is, a temperature close to the ignition point, the temperature sensor 23 transmits the detected high temperature signal to the controller 22. The controller 22 sends a signal to the electromagnet 21 according to the received high temperature signal, changes the polarity of the electromagnet 21, and thus repel each other with the magnetic part 113, disconnecting the magnetic connection between the display module 11 of the display mechanism 1 with flame retardant function and the chassis 2, achieving physical separation, isolating the fire source, preventing the fire from spreading further, and achieving a flame retardant effect. This embodiment adopts the principle of physically isolating the fire source, which can effectively prevent the fire from spreading further and protect the components inside the display module 11 or the chassis 2. If the temperature of the display module 11 is within the normal range, the temperature sensor 23 transmits the monitored normal temperature signal to the controller 22. The controller 22 controls the polarity of the electromagnet 21 to be opposite to the polarity of the magnetic part 113 according to the normal temperature signal, thereby achieving attraction between the electromagnet 21 and the magnetic part 113, and further achieving a fixed connection between the display module 11 and the chassis 2.

[0049] like Figure 3As shown in the figure, in some embodiments of the present utility model, the electromagnet 21 includes an iron core and a coil wound around the iron core. The controller 22 controls the direction of the current flowing through the coil according to the temperature signal, so that the iron core generates magnetic forces in different directions, and further controls the polarity of the electromagnet 21. The controller 22 controls the direction of the current flowing through the coil according to the received high-temperature signal, so that the electromagnet 21 generates the same polarity as the magnetic member 113, and the electromagnet 21 is disconnected from the magnetic member 113; the controller 22 controls the direction of the current flowing through the coil according to the received normal-temperature signal, so that the electromagnet 21 generates the opposite polarity to the magnetic member 113, and the electromagnet 21 and the magnetic member 113 attract each other and are fixedly connected together.

[0050] As Figure 3 shown, in some embodiments of the present utility model, the controller 22 is an STM32 microcontroller. It should be understood that the STM32 microcontroller has the advantages of high performance, low power consumption, easy programming, etc., and is an ideal choice for controlling the electromagnet 21.

[0051] In summary, the display mechanism and display device with flame-retardant function provided by the present utility model have the following beneficial effects:

[0052] (1) Quick installation and disassembly: The display module is quickly magnetically fixed and disconnected from the chassis through the magnetic member, which is convenient for installation and disassembly in case of emergency;

[0055] (4) Temperature monitoring: The built-in temperature sensor monitors the temperature of the display module, and cooperates with the controller to achieve overheat protection;

[0056] (5) Automatic control: The controller automatically controls the polarity of the electromagnet according to the temperature sensor signal, realizing the automatic fixing and release of the display module;

[0057] (6) Improve safety: Through the comprehensive design of the flame-retardant layer, the connection layer and the temperature monitoring system, the safety and reliability of the display device are improved;

[0058] (7) Reduce economic losses and casualties: The effective flame-retardant and physical isolation designs reduce the potential losses and safety risks brought by fire;

[0059] (8) Wide applicability: This design is applicable to various sizes and types of display devices, and has a wide application prospect;

[0060] The display mechanism with flame retardant function of this patent achieves efficient flame retardant protection and rapid physical isolation of the display module through innovative structural design. The magnetic fixing method is not only convenient for installation and disassembly, but also provides the possibility of rapid response in emergency situations. The dual design of the flame retardant layer and the connecting layer, combined with the temperature monitoring and automatic control system, greatly improves the safety of the display device in the event of a fire. In addition, the design also takes into account the size adaptability and operational convenience in practical applications, making it highly valuable for industrial utilization and has broad market application potential. Overall, this patent effectively solves the problems existing in the display device in the prior art in terms of fire prevention and safety through its unique design, and provides users with a safer and more reliable display solution. Therefore, the utility model effectively overcomes the various shortcomings of the prior art and has a high value for industrial utilization.
