[0027] Example

[0028] Please see Figure 1-5 The technical solution provided in this embodiment is as follows:

[0029] Example 1:

[0030] A mobile digital exhibition hall display device includes: a mobile base plate 1, with multiple casters 2 at the bottom of the mobile base plate 1; characterized in that: multiple electric telescopic rods 3 are fixedly connected to the top of the mobile base plate 1, a connecting base 5 is fixedly connected to the top of the electric telescopic rods 3, a control panel 6 is fixedly connected to one side of the top of the connecting base 5, a CNC interactive panel 7 is fixedly connected to the top of the control panel 6, and a first movable groove 10 and a second movable groove 11 for movement are provided on the surface and top of the connecting base 5; a projection component 12 is provided on the inner wall of the first movable groove 10, and an adjustment component 13 is provided on the surface of the projection component 12.

[0031] The projection component 12 and the adjustment component 13 can help the device adapt to various situations by adjusting its position and using ambient light shielding for projection.

[0032] Side protective plates 14 for shielding are fixedly connected to the top two sides of the movable base plate 1. Storage boxes 4 are fixedly connected between multiple electric telescopic rods 3. Multiple connecting telescopic rods 8 are fixedly connected to the back of the connecting base 5.

The CNC interactive panel 7 allows users to directly control the display projection, thereby increasing the overall controllability of the device. The CNC interactive panel 7 is a device and principle well known to those skilled in the art, and will not be described in detail here. The connecting telescopic rod 8 helps to fix the handle 9 when needed. When the device is extended, it moves the entire device. When the CNC interactive panel 7 is needed, it retracts, so as not to hinder the user from using it directly, thus further improving the functionality of the device. The first movable slot 10 and the second movable slot 11 can provide a range of motion for the projection component 12. The projection component 12 can use its own structure to adjust its position during projection display to achieve the desired display effect and block the light around it, thus enhancing the projection effect of the projection component 12. The adjustment component 13 can further increase the overall projection effect of the device and adjust it to achieve the desired projection effect, thus further improving the functionality of the device. The side protective plate 14 can use its own structure to protect the device from the side.

[0034] The projection assembly 12 includes a first sliding shaft 1201 and a second sliding shaft 1202. The first sliding shaft 1201 is fixedly connected to the inner wall of the first movable groove 10, and the second sliding shaft 1202 is fixedly connected to the inner wall of the second movable groove 11. A plurality of first sliders 1203 are slidably connected to the surface of the first sliding shaft 1201. A first connecting post 1204 is fixedly connected to the surface of the first slider 1203. A limit frame 1205 is fixedly connected to one end of the first connecting post 1204. A second connecting post 1206 is fixedly connected to the back of the limit frame 1205. A plurality of sliding rings 1207 are slidably connected to the surface of the second connecting post 1206. A light-blocking curtain 1208 is fixedly connected to the bottom of the sliding rings 1207.

[0035] In this embodiment, the projection component 12 is fixed inside the first movable groove 10 by the first sliding shaft 1201, while the second sliding shaft 1202 is fixed to the inner wall of the second movable groove 11. The first slider 1203 can drive the first connecting post 1204 on the surface to move during the interaction, thereby driving the position of the limiting frame 1205 to move. At the same time, the sliding ring 1207 on the surface of the second connecting post 1206 on the back of the limiting frame 1205 can provide a sliding basis for the movement of the light-blocking curtain 1208. When needed, it can be unfolded to block light from both sides, providing a better projection display environment for the projector 1209.

[0036] A projector 1209 is slidably connected to the surface of the second sliding shaft 1202. The projector 1209 is fixedly connected between multiple second connecting posts 1206. A projection port 1210 is fixedly connected to the surface of the projector 1209. A connecting plate 1211 is fixedly connected to the surface of the projector 1209. An electric pulley 1212 is provided at the bottom of the connecting plate 1211. Third connecting posts 1213 are fixedly connected to both sides of the connecting plate 1211. The other ends of multiple third connecting posts 1213 are fixedly connected to the back of the first slider 1203.

[0037] In this embodiment, the projector 1209, which slides on the surface of the second sliding shaft 1202, will be driven by the electric pulley 1212 to adjust its sliding position. Under the action of the third connecting column 1213 and the second connecting column 1206, the first slider 1203 and the limiting frame 1205 will move, thus providing a basis for the movement of the first slider 1203. The projector 1209 and the projection port 1210 can help project the parts that need to be displayed, thereby completing the basic display effect of the device.

[0038] Example 2:

[0039] Based on Embodiment 1, this embodiment considers that while Embodiment 1 alone can achieve the adjustment of the position of the projector 1209 and prevent ambient light from affecting the projector 1209, and use movement to achieve the desired display effect, in practical application, the focusing effect of the projector 1209 may be insufficient during adjustment. Therefore, this embodiment uses the following structure to enhance the focusing effect;

[0040] The adjustment assembly 13 includes telescopic columns 1301. Multiple telescopic columns 1301 are fixedly connected to the four corners of the surface of the projector 1209. One end of the bottom telescopic column 1301 is fixedly connected to a clamping base 1302, and one end of the top telescopic column 1301 is fixedly connected to a clamping top plate 1303. A threaded push column 1304 is provided on the top of the clamping top plate 1303, and a clamping plate 1305 is provided at the bottom of the threaded push column 1304. A clamping sponge 1307 is fixedly connected to the inner wall of the clamping base 1302. The clamping sponge 1307 has an opening inside, and a focusing convex lens 1306 is disposed between the clamping plate 1305 and the clamping sponge 1307.

[0041] In this embodiment, the adjustment component 13 adjusts the position of the clamping base 1302 and the clamping top plate 1303 through the telescopic column 1301. At the same time, the threaded push column 1304 can push the position of the clamping plate 1305 downward from the top, and the clamping sponge 1307 stabilizes the bottom of the focusing convex lens 1306. This clamps the focusing convex lens 1306 to facilitate the projector 1209 to focus. When needed, the focusing convex lens 1306 can also be disassembled and replaced with another type of convex lens to adapt to the projector 1209, thereby further improving the overall flexibility of the device.

[0042] The top of the clamping base 1302 is fixedly connected to multiple connecting slide rails 1308. The top of the connecting slide rails 1308 is fixedly connected to a limiting top plate 1309. The surface of the connecting slide rails 1308 is slidably connected to a sliding fixing plate 1310. A cleaning cloth 1311 is provided on the surface of the connecting slide rails 1308. The bottom of the sliding fixing plate 1310 is fixedly connected to multiple fixing clips 1312. The positions of the fixing clips 1312 match those of the cleaning cloth 1311.

[0043] In this embodiment, the cleaning cloth 1311 fixed to the surface of the connecting slide rail 1308 can wipe and clean the clamped focusing convex lens 1306 when needed. When the device is in use, it can be covered on the top of the clamping top plate 1303 and clamped and placed by the sliding fixing plate 1310 and multiple fixing clips 1312 fixed at the bottom. At the same time, when the device is not in use, it can be directly covered on the surface of the focusing convex lens 1306 to prevent dust from falling on it, thereby further improving the overall functionality of the device.

[0044] Working principle: The user can move the base plate 1 to provide a base for the moving wheels 2 to move the entire device. The electric telescopic rod 3 can help adjust the device up and down, further improving the projection effect. The storage box 4 can help place the necessary projection tools. The connecting base 5 can help support the control panel 6 and use the CNC interactive panel 7 to complete basic display interaction, further improving the functionality of the device. The connecting telescopic rod 8 can retract the fixed handle 9 when needed, making it convenient for the user to operate the CNC interactive panel 7. When it needs to be moved, the fixed handle 9 can be taken out and pushed and pulled using its own structure, further improving the functionality of the device. The first movable slot 10 and the second movable slot 11 can help provide space for the movement of the projection component 12 and the adjustment component 13 using their own internal space. The projection component 12 can use its own structure to shield the projector 1209 while helping to adjust its position according to the content being displayed, thereby further improving the flexibility of the device. The adjustment component 13 can use its own structure to help focus and magnify the projection, and can also flexibly replace components and clean, further improving the functionality of the device. The side protective plate 14 can help protect the projection component 12 from the side.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
