Generally, the control box 2 will be provided with control buttons, USB ports, etc., and the control box 2 will be set under the display screen 1, so that the operator can easily operate the control buttons on the control box 2. components to realize the control of the thin smart tablet.

In addition, there are various connection modes between the display screen 1 and the control box 2 , the display screen 1 and the control box 2 can be integrally formed, or the display screen 1 and the control box 2 can be formed separately.

Specifically, when the display screen 1 and the control box 2 are integrally formed: as shown in Figures 1 and 2, the thin smart panel also includes an outer frame (not shown in the figure), and the display screen 1 and the control box 2 are fixed in the outer frame . That is, the display screen 1 and the control box 2 share an outer frame, the display screen 1 and the control box 2 are connected by wires to realize signal or power connection, and the wiring is hidden in the control box 2 .

When the display screen 1 and the control box 2 are separately formed: as shown in Figures 3 to 6, the thin smart panel also includes an outer frame (not shown in the figure), the display screen 1 is arranged in the outer frame, and the control box 2 is arranged in the outer frame. On one side of the outer frame, the display screen 1 and the control box 2 are electrically connected through a connecting part 5 . The above-mentioned design makes the display screen 1 and the control box 2 form separate parts. When installing, it is only necessary to connect the connecting parts 5 to the display screen 1 and the control box 2 respectively, and the operation is very simple.

The display screen 1 can be connected with the control box 2 in the following three ways.

The first type: connection line connection. Specifically, as shown in FIGS. 3 and 4 , the connection component 5 is a connection wire 51 , one end of the connection wire 51 is connected to the display screen 1 through the outer frame, and the other end is connected to the control box 2 . The connecting wire 51 integrates all the lines in the control box 2 into one cable, which reduces the number of lines and the difficulty of wiring, and can also reduce the number of wiring ports on the display screen 1 and the control box 2 . In addition, when wiring, the connection wire 51 can be located in the middle or end of the control box 2 .

The second type: contact connection. Specifically, as shown in Figures 5 and 6, the connection part 5 includes a first contact part and a second contact part 52, the first contact part is arranged on the outer frame and connected to the display screen 1, and the second contact part 52 It is arranged on the control box 2 and connected with the control components inside the control box 2 , when the display screen 1 is installed on one side of the control box 2 , the second contact part 52 abuts against the first contact part.

In order to ensure that the two contact parts can be aligned accurately when the control box 2 and the display screen 1 are assembled, a positioning component 6 is also added. Specifically, the positioning component 6 includes a positioning protrusion 61 and a positioning groove 62 that are plug-fitted. One of the positioning protrusion 61 and the positioning groove 62 is arranged on the side of the outer frame facing the control box 2, and the other of the positioning protrusion 61 and the positioning groove 62 is arranged on the side of the control box 2 facing the outer frame. On one side, when the positioning protrusion 61 is mated with the positioning groove 62 , the second contact portion 52 abuts against the first contact portion.

The third group: wireless connection. Specifically, referring to accompanying drawings 5 and 6, the connection part 5 includes a first wireless module and a second wireless module, the first wireless module is arranged in the outer frame, the second wireless module is arranged in the control box 2, the first wireless module and the display The screen 1 is connected, and the second wireless module is connected with the control components in the control box 2.

In a preferred embodiment of the present invention, as shown in FIGS. 7 to 11 , the thin smart tablet is fixed on the installation surface 3 by means of magnetic fixation. Specifically, the thin smart tablet further includes a magnetic attraction assembly 7 for magnetically fixing the display screen 1 and the control box 2 on the installation surface 3 .

Taking the integrally formed thin smart tablet as an example, the structure of the outer frame 4 refers to FIG. 42 is connected to the side of the side frame 41 close to the installation surface 3, and is used to isolate the display screen 1 and the control box 2 from the installation surface 3. The magnetic attraction assembly 7 includes at least two first magnets 71 and at least two second magnets 72 , at least two first magnets 71 are spaced apart on the rear cover 42 , at least two second magnets 72 are spaced apart on the mounting surface 3 , and the first magnets 71 and the second magnets 72 correspond in positions and have opposite magnetic properties.

In order to increase the installation reliability of the thin smart tablet, both the first magnet 71 and the second magnet 72 are powerful magnets.

Further, it also includes a latch assembly 8, which includes a latch 81 and a socket 82, the latch 81 is fixed on the installation surface 3, the socket 82 is opened on the rear cover 42, and the end of the latch 81 away from the installation surface 3 is selectively Insert into jack 82. By setting the latch assembly 8, utilizing the cooperation of the latch 81 and the jack 82, the thin smart panel can be supported in the vertical direction, reducing the force acting on the magnetic attraction assembly 7, due to the gravity of the thin smart panel with the large screen It is heavier, therefore, the additional pin assembly 8 can improve the installation stability, and during the installation process, the alignment can be achieved through the pin assembly 8, ensuring that the first magnet 71 and the second magnet 72 can be accurately adsorbed, reducing the difficulty of installation, Further improve the installation reliability of the thin smart tablet.

Further, the height of the first side wall 212, the height of the second side wall and the height of the fourth side wall are equal, the height of the third side wall 213 is less than the height of the first side wall 212, and the height of the lid side plate 222 is the same as that of the fourth side wall. The heights of the first sidewalls 212 are equal.

In yet another embodiment of the present utility model, as shown in FIG. 12 , a processor 24, a video control board 25 and a power supply system 26 are sequentially arranged on the bottom wall 211 of the box body 21 along the length direction of the box body 21, and the processor 24 is connected with video control board 25, and video control board 25 is connected with external display screen 1, and power supply system 26 is connected with video control board 25 and processor 24 respectively, is provided with the first side away from power supply system 26 on video control board 25 A heat dissipation fan 271 , and a second heat dissipation fan 272 is provided on the side of the power supply system 26 away from the video control board 25 . By arranging a heat dissipation fan on each side of the two components with large heat generation (video control board 25 and power supply system 26), the heat dissipation efficiency can be improved.

The first cooling fan 271 is disposed adjacent to the processor 24 . Such a design can speed up the heat dissipation on the processor 24 and ensure that the processor 24 can work normally.

Both the first heat dissipation fan 271 and the second heat dissipation fan 272 are exhaust fans, and the bottom wall 211 is provided with an air outlet (not shown) corresponding to the first heat dissipation fan 271 and the second heat dissipation fan 272 .

The first loudspeaker 281 is arranged on the side of the processor 24 away from the video control board 25, and the corresponding first loudspeaker 281 on the bottom wall 211 offers the first sound outlet (not shown); A second speaker 282 is arranged on the side, and a second sound outlet is provided on the bottom wall 211 corresponding to the second speaker 282 . The sound hole can not only facilitate the diffusion of the sound of the speaker to the outside of the control box 2, but also can be used as an air inlet for the cooling fan.

The second speaker 282 is disposed between the power system 26 and the second cooling fan 272 ; or, the second speaker 282 is disposed on a side of the second cooling fan 272 away from the power system 26 .
