[0015] Compared with the related art, the present invention has the following beneficial effects:

[0016] 1.

The electric push rod is used to adjust the position of the slide plate and the outer frame outside the motion sensor. When the outer frame moves backward, the boundary marking line of the right laser plate moves to the left, and the boundary marking line of the left laser plate moves to the right. At this time, the boundary marking line on the left side of the standing area moves to the left, and the boundary marking line on the right side of the standing area moves to the right. The outer frame outside the motion sensor moves backward, the field of view of the motion sensor increases, and the range mark of the standing area also increases accordingly, so that the device can automatically adjust the field of view indication range according to the field of view of the motion sensor. By limiting the field of view, the interaction problems caused by the user standing outside the screen or in an inappropriate position can be reduced, the response efficiency and accuracy of the interactive display device are improved, external interference is reduced, and the problem that the existing interactive display device cannot automatically adjust the field of view indication range according to the field of view of the motion sensor is solved.

[0017] 2. Through the extension component on the device, the extension component can change the initial position of the pressure plate. At the same time, the device can also change the initial elastic force of the torsion spring by installing the third card rod in the card slot at different positions, so that the device can adjust the initial value of the field of view of the motion sensor, so that the device can adapt to different environments and accurately adjust the field of view of the motion sensor. And the device can adjust the depression or elevation angle of the motion sensor and the camera by adjusting the ball shaft on the assembly to adapt to users of different heights, thereby enhancing the applicability of the device.

[0018] 3. By setting the first extension plate, the second extension plate and the docking assembly, when the first extension plate and the second extension plate are extended outward, the first elastic band and the second elastic band on the docking assembly will pull the first push plate and the second push plate, and the oblique cut surfaces of the first push plate and the second push plate can abut against the oblique cut surfaces at the bottom of the first clamping rod and the second clamping rod, and the oblique cut surfaces at the bottom of the first clamping rod and the second clamping rod are facing oppositely. Therefore, when the first push plate and the second push plate move in opposite directions, the first clamping rod and the second clamping rod will move upward, so that the first clamping rod and the second clamping rod are moved into the docking hole of the first connecting frame, so that the first connecting frame and the first display screen automatically maintain a clamping state, and when the first extension plate and the second extension plate are stored, the first elastic band and the second elastic band are changed from a stretched state to a relaxed state, and the first push plate and the second push plate no longer abut against the bottom of the first clamping rod and the second clamping rod, so that the first clamping rod and the second clamping rod automatically fall down, so that the first display screen and the first connecting frame can be removed from the device, thereby enhancing the convenience and safety of the device when used.

The initial angle of the rotating plate 2001 can be adjusted by pulling the lap rod 2007, the third card rod 2008 and the third key block 2006 upward, and then rotating the connecting shaft 2004 to a certain angle, and then installing the third key block 2006 into the connecting shaft 2004, and installing the third card rod 2008 into the slots 2009 at other positions, so as to adjust the initial angle of the rotating plate 2001, so as to adjust the initial field of view of the device later.

Mounting rods 2105 are arranged in the second mounting holes 2104 and the first mounting holes 2103. When the slide plate 19 moves backward, the field of view of the device increases, and the pressing plate 2102 can abut against the rotating plate 2001 to rotate the rotating plate 2001, thereby automatically increasing the marking area of ​​the field of view. When the slide plate 19 moves forward, the field of view of the device decreases. At the same time, the rotating plate 2001 can rotate in the opposite direction, thereby automatically reducing the marking area of ​​the field of view.

[0044] The specific implementation process of the present invention is as follows: Figure 1-Figure 8As shown, when the device is in use, the first connecting frame 2 is supported by the base 1 and the support plate 3, the rear plate 5 and the connecting plate 6 are used to support the first connecting frame 2 and the first display screen 4, the camera 14 and the motion sensor 16 are used to shoot and capture the user's body movements. When the device is in use, the forward extension length of the outer frame 17 and the slide plate 19 can be adjusted according to the size of the venue and the density of people in the venue, thereby changing the field of view of the motion sensor 16. When there are many people in the venue where the device is used, the field of view of the motion sensor 16 can be appropriately reduced. When there are fewer people using the site, the field of view of the motion sensor 16 can be appropriately increased. At this time, the slide plate 19 and the outer frame 17 can be moved backward by extending the electric push rod 18, and the second connecting plate 2101 on the extension component 21 can be connected with the mounting rod 2105 in the first mounting hole 2103 and the second mounting hole 2104, so that the pressing plate 2102 moves backward. When the pressing plate 2102 moves backward, it can abut against the rotating plates 2001 on the left and right sides of the shell 15. The rotating plate 2001 on the left rotates counterclockwise, and the rotating plate 2001 on the right rotates clockwise. Since the laser plate 2003 on the left column 2002 marks the field of view mark line on the right side of the ground, the laser plate 2003 on the right column 2002 marks the field of view mark line on the left side of the ground, as shown in FIG. Figure 1 As shown, when the outer frame 17 moves backward, the field of view of the motion sensor 16 increases. At this time, the boundary marking line on the left side of the standing area moves to the left, and the boundary marking line on the right side of the standing area moves to the right. The field of view of the motion sensor 16 increases, and the range mark of the standing area also increases accordingly, so that the device can adaptively adjust the range indication range of the ground mark according to the field of view of the motion sensor 16, ensuring that the device can adjust the field of view of the device and the range of the standing area according to the size of the use site and the number of people using the site. The device can adjust the elevation or depression angle of the second connecting frame 8 and the second display screen 9, such as Figure 3 and Figure 5 As shown, the angle of the connection block 704 and the second connection frame 8 is adjusted by the ball shaft 703. Since the support block 701 and the first connection plate 705 are both made of rubber and abut against each other, there is friction between the support block 701 and the first connection plate 705, so that the device can remain fixed after adjusting the angle of the second display screen 9. By adjusting the depression angles of the second display screen 9, the camera 14 and the motion sensor 16, the device can be used by people of different heights. When the device is in use, the lap rod 2007, the third clamping rod 2008 and the third key block 2006 are pulled upward, and then the connection shaft 2004 is rotated to a certain angle, the torsion spring 2005 drives the rotating plate 2001 to rotate, the third key block 2006 is installed in the connection shaft 2004, and the third clamping rod 2008 is installed in the clamping slot 2009 at the remaining position, so as to adjust the initial angle of the rotating plate 2001, so that the device can adjust the initial field of view of the motion sensor 16.

[0045] like Figure 7 and Figure 9-11 As shown, the device can extend its own support range. By pulling the first extension plate 10 forward and the second extension plate 11 backward, the second protrusion 1204 slides inside the second slide groove 1203, the first protrusion 1202 slides inside the first slide groove 1201, and the second protrusion 1204 slides inside the first slide groove 1201, thereby ensuring smooth movement of the first extension plate 10 and the second extension plate 11, so that the support range of the front and rear sides of the support plate 3 is extended. When the first extension plate 10 and the second extension plate 11 move outward, the first extension plate 10 pulls the second push plate 1306 through the second elastic band 1309, and the second extension plate 11 pulls the first push plate 1305 through the first elastic band 1308, and the first push plate 1305 and the second push plate 1306 move back to back, and the inclined surfaces of the first push plate 1305 and the second push plate 1306 abut against the inclined surfaces at the bottom of the first card rod 1301 and the second card rod 1303 and push the first card rod 1301 and the second card rod 1303 upward. At this time, the first clamping rod 1301 and the second clamping rod 1303 move upward to the docking hole 26 in the first connecting frame 2 through the connecting sleeve 1307, so that the device automatically fixes the first display screen 4 after extending the front and rear support range, and when the first extension plate 10 and the second extension plate 11 are stored, the first elastic band 1308 and the second elastic band 1309 are relaxed, and the first clamping rod 1301 and the second clamping rod 1303 move downward, and the first connecting frame 2 and the first display screen 4 can be removed from the device.
