[0035] Monitoring display screens usually need to work continuously for 24 hours to ensure real-time monitoring of important areas. However, the heat generation caused by long-term operation increases significantly, especially when multiple screens are used in a tiled manner, and the heat problem becomes more prominent. High temperatures can not only affect the performance of digital intelligent display screens but also shorten their service life. Therefore, when designing and deploying a monitoring display system, how to consider effective heat dissipation measures to extend the stability and life of the equipment has become an urgent problem to be solved.

[0036] The present utility model proposes a digital intelligent display screen.

[0037] It should be noted that the subject name of this application is a digital intelligent display screen, where "digital intelligent" means the combination of "digital" and "intelligent", usually referring to a display device that combines digital display technology and intelligent functions. In practical applications, digital intelligent display screens generally have characteristics such as high resolution, intelligent functions, interactivity, and networking capabilities, and are more suitable for use in fields such as video monitoring.

[0038] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the digital intelligent display screen 100 includes a frame 110, a display screen main body 120, and a heat dissipation component 130. Opposite two sides of the frame 110 along the first direction are provided with an air inlet 110a and an air outlet 110b. As Figure 1 marked in the figure, the first direction is the height direction of the digital intelligent display screen 100. The display screen main body 120 is installed on the front side of the frame 110 for displaying images. The rear side of the frame 110 away from the display screen main body 120 is an open setting, which is convenient for personnel to perform installation and debugging operations from the rear side. A air duct is formed by enclosing between the display screen main body 120 and the frame 110. The air duct extends along the first direction and is communicated with the air inlet 110a and the air outlet 110b. The heat dissipation component 130 is arranged at the air inlet 110a and the air outlet 110b to generate an air flow in the air duct. The outside air enters the air duct from the air inlet 110a and blows out the heat generated by the display screen main body 120 from the air outlet 110b, so as to dissipate heat from the display screen main body 120 and extend the stability and service life of the equipment.

[0039] It should be noted that in actual application scenarios, the rear side of the frame 110 is generally set against the wall. The wall surface, the frame 110, and the display screen main body 120 enclose a hollow cavity. The display screen main body 120 includes components such as a display panel and a control main board connected to the panel. During long-term operation, a large amount of heat will be generated. If heat dissipation is not carried out, the accumulated heat inside will cause damage to electronic components, affecting the display effect and the service life of the display screen. And in this solution, an air duct is arranged along the height direction of the cavity, and the heat in the cavity is taken away by combining the air inlet 110a, the air outlet 110b, and the heat dissipation component 130. In some other embodiments of the present utility model, the air duct can also be arranged along the width direction of the digital intelligent display screen 100, and the positions of the air inlet 110a and the air outlet 110b correspond to the air duct, and no specific limitation is made here.

[0040] In one embodiment, the frame 110 includes a first side frame 111 and a second side frame 112. The first side frame 111 and the second side frame 112 are arranged on opposite sides in the height direction of the digital intelligent display screen 100. The air inlet 110a is arranged on one of them, and the air outlet 110b is arranged on the other.

[0041] As Figure 3 shown, in one embodiment of the present utility model, the frame 110 includes a first side frame 111 and a second side frame 112. Specifically, the first side frame 111 is arranged at the bottom of the digital intelligent display screen 100, and the second side frame 112 is arranged opposite to the first side frame 111 and is located at the top of the digital intelligent display screen 100. The air inlet 110a is opened on the first side frame 111, and the air outlet 110b is opened on the second side frame 112. Heat dissipation components 130 are respectively arranged at the air inlet 110a and the air outlet 110b. The air inlet 110a and the air outlet 110b are aligned along the first direction. The heat dissipation component 130 on the first side frame 111 draws air into the air duct from the air inlet 110a, and the air flow carries heat and flows through the back of the display screen main body 120. The heat dissipation component 130 on the second side frame 112 blows air from the air duct to the air outlet 110b to dissipate the heat inside the digital intelligent display screen 100 to the outside, ensuring the stability of the display screen during long-term operation. Of course, in some other embodiments, the installation of the heat dissipation component 130 can be adjusted according to the installation posture of the display screen and the direction of the air duct to make the air duct reasonable.

[0042] In one embodiment, the first side frame 111 and / or the second side frame 112 are / is provided with ventilation holes 113 penetrating along the first direction. The air inlet 110a and / or the air outlet 110b are / is communicated with the ventilation holes 113. The heat dissipation component 130 is arranged inside the first side frame 111 and / or the second side frame 112 and is located inside the ventilation holes 113.

[0043] As Figure 3 and Figure 5As shown, in an embodiment of the present utility model, the first frame 111 and the second frame 112 have a certain thickness in the first direction and are provided with ventilation holes 113 therethrough. An air inlet 110a is provided on the surface of the first frame 111 away from the display screen body 120 and is communicated with the ventilation hole 113. An air outlet 110b is provided on the surface of the second frame 112 away from the display screen body 120 and is communicated with the ventilation hole 113. Heat dissipation components 130 are respectively arranged in the ventilation holes 113 of the first frame 111 and the second frame 112. It can be understood that the first frame 111 and the second frame 112 having a certain thickness can protect the edge of the display screen body 120. At the same time, the space of the ventilation holes 113 is utilized to install the heat dissipation components 130, which can improve the space utilization rate, and the heat dissipation components 130 will not interfere with the installation of the display screen body 120, facilitating the operation of the staff from the rear side of the digital display screen 100, and the structural setting is more reasonable.

[0044] In an embodiment, the first frame 111 and / or the second frame 112 are hollow tubes and are provided with an installation channel 114 therethrough along the second direction. The installation channel 114 is communicated with the ventilation hole 113 for the heat dissipation component 130 to enter the inside of the first frame 111 or the second frame 112 and move to the ventilation hole 113 for installation.

[0045] As Figure 5 As shown, in an embodiment of the present utility model, both the first frame 111 and the second frame 112 are tubular structures with a hollow interior. The first frame 111 and the second frame 112 extend along the second direction and are respectively arranged on the upper and lower sides of the display screen body 120. Installation channels 114 are respectively provided through the first frame 111 and the second frame 112 along the second direction, and the installation channels 114 are communicated with the ventilation holes 113. The volume of the heat dissipation component 130 is larger than the widths of the air inlet 110a and the air outlet 110b. During assembly, the heat dissipation component 130 can enter the inside from both ends of the first frame 111 or the second frame 112 along the installation channel 114, move along the installation channel 114 and reach the ventilation hole 113 for installation and fixation. By using the hollow structures of the first frame 111 and the second frame 112, the integration degree of the heat dissipation component 130 and the frame 110 is higher after combination, improving the installation convenience.

[0046] In an embodiment, the heat dissipation component 130 includes a fan 131 and a dust-proof member 132. The dust-proof member 132 is arranged on the fan 131 and extends towards the air inlet 110a or the air outlet 110b to close the gap between the fan 131 and the air inlet 110a or the air outlet 110b.

[0047] As Figure 4 and 6As shown, in an embodiment of the present utility model, the heat dissipation component 130 includes a fan 131 and a dust-proof member 132. Specifically, the fan 131 is used to generate air flow. When the fan 131 is disposed within the first frame 111 or the second frame 112, its bottom abuts against the inner wall surface of the installation channel 114, and there is a certain distance between the upper surface of the fan 131 and the air inlet 110a or the air outlet 110b. To prevent dust and the like from entering the gap between the fan 131 and the air inlet 110a or the air outlet 110b, a dust-proof member 132 is installed on the side of the fan 131 facing the air inlet 110a or the air outlet 110b. The dust-proof member 132 is disposed to surround the circumference of the fan 131, and the end of the dust-proof member 132 away from the fan 131 fits against the edge of the air inlet 110a or the air outlet 110b. The annular structure seals the gap therebetween, preventing impurities such as dust and water from entering the gap between the fan 131 and the air inlet 110a or the air outlet 110b.

[0048] In one embodiment, the heat dissipation component 130 further includes a buffer member 133. The buffer member 133 is disposed on the side of the fan 131 away from the dust-proof member 132 and abuts against the frame 110, for reducing the vibration of the fan 131.

[0049] As Figure 6 and 7 As shown, in an embodiment of the present utility model, the heat dissipation component 130 further includes a buffer member 133. Specifically, the buffer member 133 is a buffer pad disposed at the bottom of the fan 131. A through hole is formed in the center of the buffer member 133 for air intake, and the surfaces on both sides abut against the opposite sides of the fan 131 and the inner wall of the installation channel 114. Generally, it is made of materials such as rubber and has a certain elasticity. During the rotation of the fan 131, the buffer member 133 can offset a part of the impact vibration, enabling the digital display screen 100 to operate quietly. Further, the dust-proof member 132 can also be made of rubber material to avoid loosening and collision, improving the operating stability of the heat dissipation component 130.

[0050] In one embodiment, the number of the air inlets 110a and / or the air outlets 110b is multiple. The multiple air inlets 110a and / or the multiple air outlets 110b are arranged at intervals along the second direction on the frame 110, and a heat dissipation component 130 is provided at each of the air inlets 110a and the air outlets 110b.

[0051] As Figures 1 to 3As shown, in an embodiment of the present utility model, the number of air inlets 110a and air outlets 110b is multiple. The multiple air inlets 110a are arranged at intervals along the length direction of the first frame 111, and the multiple air outlets 110b are arranged at intervals along the length direction of the second frame 112. Each air inlet 110a and air outlet 110b correspond one by one and are aligned in the first direction. A air duct is formed between each air inlet 110a and air outlet 110b. A heat dissipation component 130 is installed in the ventilation hole 113 located at the air inlet 110a or air outlet 110b. By setting multiple air inlets 110a and air outlets 110b, multiple air ducts are formed within the frame 110, which can accelerate the heat dissipation speed inside the display screen and improve the heat dissipation efficiency.

[0052] In an embodiment, the number of display screen bodies 120 is multiple, and the multiple display screen bodies 120 are assembled in a rectangular structure.

[0053] As Figures 1 to 3 shown, in an embodiment of the present utility model, the number of display screen bodies 120 is multiple. Specifically, the specifications of each display screen body 120 are the same. After the multiple display screen bodies 120 are spliced into a rectangular shape, the first frame 111 and the second frame 112 are respectively arranged on both sides of the assembled screen in the height direction, and then the two frames in the width direction clamp both sides of the assembled screen and are respectively connected to the two ends of the first frame 111 and the second frame 112 to form the frame 110, so as to form a wrap-around for the combination of the multiple display screen bodies 120 spliced. The multiple display screen bodies 120 are stacked in the first direction and arranged in multiple columns in the second direction. Air outlets 110b and air inlets 110a are respectively arranged on the upper and lower sides of each column. The middle air duct can dissipate heat for the display screen body 120 in this column, improving the heat dissipation effect.

[0054] Furthermore, please refer to Figures 8 to 10 , in another embodiment of the present utility model, the display screen body 120 is an LED screen. The difference from the assembled screen is that the support structure of the LED screen occupies less space than that of the assembled screen, making the interior of the digital display 100 more spacious and the gas flow smoother, which can effectively improve the heat dissipation effect. It should be noted that in addition to the above-listed assembled screen and LED screen, in some other embodiments of the present utility model, the frame 110 and the heat dissipation component 130 can also be used for heat dissipation of some other types of screens, such as OLED screens, plasma screens, etc., which will not be specifically limited here.

[0055] In actual production, after the display screen main body 120 is assembled, it is fixed using the bracket assembly 140, and the edges of the display screen main body 120 are wrapped by the respective side frames of the frame 110. The frame 110 and the display screen main body 120 enclose to form an air duct, and thus the display screen main body 120 can be cooled through the heat dissipation component 130 on the frame 110. As can be seen above, the edge wrapping process enables the frame 110 and the heat dissipation component 130 to have a wider range of applications and can adapt to different display screens by changing the size.

[0056] It should be noted that since there is no limit to the size of the screen, the number of the heat dissipation components 130 is not limited either. If the size of the display screen main body 120 after assembly is less than two square meters, there is no need to set the heat dissipation component 130. Starting from two square meters, there is no upper limit. The number of the heat dissipation components 130 increases with the increase of the square number, that is, the number of the fans 131 increases to ensure the heat dissipation effect and maintain the temperature inside the digital display screen 100 within a certain range. The actual product can determine the distribution positions of multiple fans 131 according to different screen types and the length and width of the frame 110, and no specific limitation is made here.

[0057] In one embodiment, the digital display screen 100 further includes a bracket assembly 140. The bracket assembly 140 is disposed on the frame 110, and the display screen main body 120 is connected to the frame 110 through the bracket assembly 140.

[0058] Such as Figure 3 and Figure 7 As shown, in an embodiment of the present utility model, the digital display screen 100 further includes a bracket assembly 140. Specifically, the display screen main body 120 is fixed on the frame 110 through the bracket assembly 140. Since the bracket assembly 140 has a certain height in the third direction (i.e., the thickness direction of the digital display screen 100), when connected to the frame 110, a space for the air duct is formed between the display screen main body 120 and the rear side of the frame 110, which not only plays a role in fixing but also leaves a space for the air duct, and is also convenient for production personnel to assemble and join, reducing the installation difficulty.

[0059] In one embodiment, the bracket assembly 140 includes a first connecting member 141 and a second connecting member 142. The first connecting member 141 and the second connecting member 142 are arranged at intervals along the first direction, and the air duct is disposed between the first connecting member 141 and the second connecting member 142.

[0060] Such as Figure 3 and Figure 4As shown, in an embodiment of the present utility model, the bracket assembly 140 includes a first connecting member 141 and a second connecting member 142. Specifically, in order to ensure the supporting performance of the bracket assembly 140 for the display screen main body 120, the bracket assembly 140 is provided with the first connecting member 141 and the second connecting member 142. The first connecting member 141 and the second connecting member 142 are both arranged to extend along the first direction and are attached to the back structure of the display screen main body 120. It can be understood that at least 4 connection points can be provided on the first connecting member 141 and the second connecting member 142 to support four regions on the back of the display screen main body 120, so as to make the supporting effect better and the connection more stable. Further, the first connecting member 141 and the second connecting member 142 are respectively arranged on both sides of the air duct to avoid blocking the air flow and ensure the heat dissipation effect.

[0061] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
