[0053] The present invention provides a display device 100 that can be used in scenarios requiring data display and / or control and adjustment. For example, it can be used to display and control the operating status of large equipment. The display device 100 can be compatible with a computer (such as an all-in-one computer) or can be connected to the computer via wired or wireless communication.

[0054] Specifically, see Figures 1 to 3 In this embodiment, the display device 100 includes a housing 1, a display screen 2, an electronic component 3 and a plurality of conductive seals 4. The housing 1 includes a front frame 11, a middle frame 12 and a back cover 13 that are connected to each other. The front frame 11, the middle frame 12 and the back cover 13 together enclose a receiving cavity; the display screen 2 is arranged on the front frame 11 to seal the front side of the receiving cavity; the electronic component 3 is arranged in the receiving cavity, and the electronic component 3 can be covered and protected by the housing 1; the plurality of conductive seals 4 are arranged at the connection gaps between the display screen 2, the front frame 11, the middle frame 12 and the back cover 13, and form a seal for each of the connection gaps.

[0055] In this embodiment, the display screen 2 can be fixed by the housing 1, and the electronic component 3 is set in the accommodating cavity of the housing 1 to cover the electronic component 3, which can better protect the electronic component 3 from damage. Moreover, in order to facilitate the assembly of the display device 100, the housing 1 includes a front frame 11, a middle frame 12 and a back cover 13. During assembly, the display screen 2 can be fixed to the front frame 11 first, and then the electronic component 3 can be fixed to the middle frame 12. Then, the front frame 11, the middle frame 12 and the back cover can be assembled in sequence. 13, making assembly faster and more convenient, and easy to maintain each component; moreover, conductive seals 4 are provided at the connection gaps between the display screen 2, the front frame 11, the middle frame 12 and the back cover 13. The conductive seals 4 can, on the one hand, form a seal at each of the connection gaps to prevent dust and other debris from entering the housing 1, and on the other hand, effectively prevent electromagnetic leakage, so as to effectively improve the impact of the display device 100 on peripheral electrical appliances, and at the same time, reduce the interference of peripheral electrical appliances on the display device 100, so that the working performance of the display device 100 is more stable.

[0056] The housing 1 is a shell structure used to fix the display screen 2 and protect the electronic components 3. Preferably, the housing 1 is made of metal to ensure better electromagnetic shielding effect. The shape of the housing 1 is similar to that of a traditional display. The side of the display device 100 on which the display screen 2 is provided is the front side, and the side opposite thereto is the rear side. In sequence, the front frame 11, the middle frame 12 and the rear cover 13 are connected and arranged in sequence along the front-to-back direction. When the display screen 2 is displaying normally, the up-down direction of the image normally displayed by the display screen 2 is the up-down direction of the display device 100, and the left-right direction of the image displayed by the display screen 2 is the left-right direction of the display device 100. The description of the relevant directions in this utility model can be referred to in this manner.

[0057] Preferably, combined Figure 4 and Figure 5As shown, the front frame 11 includes a front wall 111, a first side wall 112, and a first retaining wall 113. The front wall 111 is annular and generally square and flat, with a hollowed-out area in the middle forming an area for exposing the display screen 2. The first side wall 112 is disposed on the outer periphery of the front wall 111 and extends rearward. The first side wall 112 is annular and surrounds the outer periphery of each side of the front wall 111. The first retaining wall 113 is disposed at the end of the first side wall 112 and is bent along the side of the first side wall 112 toward the middle area of ​​the front wall 111. The first retaining wall 113 is generally L-shaped. The side of the first retaining wall 113 connected to the first side wall 112 is connected to the middle frame 12, and the other side of the first retaining wall 113 abuts against the middle frame 12. The first side of the first retaining wall 113 extends downward from the first side wall 112, and the second side of the first retaining wall 113 extends backward from the first side to abut against the middle frame 12, so that the middle frame 12 and the front frame 11 are relatively fixed and their relative positions are more accurate. The second side of the first retaining wall 113 can form a certain shielding for the connection gap between the middle frame 12 and the front frame 11.

[0058] Among them, combined Figure 4 and Figure 6 As shown, the front frame 11 further includes a plurality of fixing brackets 114, which are disposed on the inner side of the front wall 111 and surround the outer periphery of the display screen 2. The plurality of fixing brackets 114 are arranged in a ring shape to surround the periphery of the display screen 2, thereby completely fixing the display screen 2 to the front wall 111 and ensuring the stability of the display screen 2. Furthermore, at least one conductive seal 4 is disposed between each fixing bracket 114 and the display screen 2 to form a better seal between the display screen 2 and the front wall 111, effectively preventing electromagnetic leakage.

[0059] Further, combined with Figure 7 and Figure 8As shown, the middle frame 12 includes a frame 121, a second side wall 122, and a second retaining wall 123. The frame 121 is annular and spaced apart from the front wall 111. The frame 121 has a flat connecting portion and a groove-shaped structure protruding rearward from the connecting portion. The groove-shaped structure defines a sufficient space between the front frame 11 to facilitate installation of the electronic component 3. The connecting portion of the frame 121 is connected to the first side wall 112, specifically by bolts or screws, to ensure the stability of the connection between the middle frame 12 and the front frame 11. The second side wall 122 is disposed on the outer periphery of the frame 121 and extends forward. The second side wall 122 abuts the first side wall 112 and at least partially overlaps the first retaining wall 113. The second side wall 122 is located above the second side of the first retaining wall 113, thereby enhancing the structural strength between the middle frame 12 and the front frame 11 and preventing the bolts or screws connecting the front frame 11 and the middle frame 12 from being exposed to the outside, thereby improving the appearance and achieving a better sealing effect. The second retaining wall 123 is disposed on the front side of the frame 121 and is adapted to be disposed with the first retaining wall 113. The second retaining wall 123 is also generally L-shaped to engage with the first retaining wall 113. At least one conductive seal 4 is disposed between the first retaining wall 113 and the second retaining wall 123. The conductive seal 4 further seals the gap at the connection between the front frame 11 and the middle frame 12 to better prevent electromagnetic leakage within the housing 1.

[0060] Preferably, each of the conductive seals 4 can be configured as a conductive copper film, which can better achieve electromagnetic shielding.

[0061] Among them, such as Figure 8 As shown in FIG, a convex wall 124 extends rearward from the rear opening of the frame 121; the rear cover 13 includes a rear wall 131 and a third side wall 132. The rear wall 131 covers the rear opening of the frame 121 and abuts the convex wall 124. The rear wall 131 is connected to the frame 121; the third side wall 132 extends forward from the rear wall 131 and abuts the rear side of the frame 121. The third side wall 132 is arranged around the outer periphery of the convex wall 124. Similarly, the convex wall 124, the rear wall 131, and the third side wall 132 form a mutually abutting cavity structure, thereby ensuring better strength of the rear cover 13.

[0062] Furthermore, the back cover 13 also includes a first cover body 133 and a second cover body 134. The first cover body 133 is arranged on the front side of the back wall 131 and has a first convex ring protruding forward; the second cover body 134 is arranged on the front side of the first cover body 133 and has a second convex ring protruding forward. The second convex ring is sleeved on the outer peripheral side of the first convex ring and is located on the inner side of the convex wall to further increase the strength of the back cover 13 and ensure the stability and reliability of the entire display device 100.

[0063] In addition, since the display device 100 contains a large number of electronic components 3, the operating heat is also relatively high. The display device 100 also includes a cooling fan 5 disposed within the accommodating cavity. The middle frame 12 is provided with cooling holes on both sides of the axial direction corresponding to the cooling fan 5. The cooling fan 5 can quickly discharge the heat generated by the electronic components 3 within the accommodating cavity through the cooling holes to ensure the stability of the operation of the electronic components 3. However, if cooling holes are provided, electromagnetic leakage will occur. Furthermore, the display device 100 also includes two waveguide windows 6, which are respectively provided on the outside of the corresponding cooling holes on both sides. By customizing the waveguide windows 6 with specific shapes for different electronic components 3, electromagnetic leakage can be effectively avoided. This ensures that the temperature of the display device 100 itself is not too high, and electromagnetic leakage can be better avoided, thereby improving operational stability.

[0064] Among them, the waveguide window 6 includes a window plate and a cover connected to the window plate, the window plate is provided with a plurality of through holes arranged in a honeycomb shape, the cover is provided with a long hole opposite to the plurality of through holes, and a baffle is also provided on the outside of the long hole, an air outlet channel is formed between the baffle and the long hole, and the airflow flowing out of the shell 1 can pass through the plurality of through holes and then flow toward the long hole or the gap between the long holes. The plurality of baffles can block the through holes to prevent debris from entering the shell 1.

[0065] In one embodiment, the display device 100 also includes a wall-mounted mounting plate 7 and a shock-absorbing component; the wall-mounted mounting plate is used to be connected to the wall surface waiting for installation, and the shock-absorbing component is connected to the wall-mounted mounting plate 7 and the middle frame 12. The shock-absorbing component can effectively reduce the vibration of the outer casing 1 and the display screen 2, thereby better protecting the display device 100.

[0066] Preferably, if Figure 1 and Figure 2As shown in FIG, the shock-absorbing component includes a shock-absorbing frame 81 and a shock-absorbing steel cable 82. The shock-absorbing frame 81 is connected to the middle frame 12; the shock-absorbing steel cable 82 connects the shock-absorbing frame 81 to the wall-mounting plate 7. When the display device 100 is used in a mobile environment, such as on a ship or in a car, vibration and impact are relatively severe. Therefore, the shock-absorbing steel cable 82 can better prevent hard collisions between the housing 1 and the display screen 2, thereby ensuring the stability of the display device 100.

[0067] Moreover, two sets of the wall-mounted mounting plates 7 and the shock-absorbing components are provided, which are symmetrically arranged on the left and right sides of the middle frame 12 to ensure that the display device 100 is fixed more stably.

[0068] Among them, the function and size of the display screen 2 are not specifically limited, and the size of the housing 1 is adapted to the size of the display screen 2. The display screen 2 may be a touch-screen liquid crystal display screen 2. A back panel and a gripping portion provided on the rear side of the back panel are also provided on the back of the display screen 2. The back panel is fixed to the display screen 2. During assembly, the gripping portion may be installed and removed to facilitate the transfer of the display screen 2, thereby facilitating the assembly and transfer of large-sized display screens 2. The electronic component 3 may include a drive module and a communication module, etc., so as to better electrically connect to the remote device and display and adjust the remote device. The display device 100 can realize traditional display operation functions, and the operation is more stable and the electromagnetic shielding effect is better, so the user experience is better.
