Description

Technical Field

[0001] The utility model relates to the technical field of projection devices, in particular to a visual communication projection device. Background Art

[0002] Visual communication design mainly uses visual symbols, signs and graphics to convey ideas and values, so a projection device is needed to embody them. Currently, projection devices are usually implemented using projectors, and the projector needs to be fixed at a high place using a suitable bracket, and the location needs to be open to ensure the normal operation of the projector.

[0003] Traditional projectors often face issues with fixed positioning and difficult to adjust height and projection direction, which greatly limits their flexibility and applicability. This is particularly true in situations where frequent adjustments to the projection position or direction are required, such as outdoor exhibitions and impromptu meetings. The fixed installation method of traditional projectors often fails to meet practical needs. Therefore, to address these issues, we propose a visual communication projection device.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0021] Reference Figure 1-3 A visual communication projection device includes a base plate 1, a hollow column 2 is fixedly installed on the rear side of the top of the base plate 1, an L-shaped rod 3 is inserted into the interior of the hollow column 2, a servo 5 is fixedly installed on one end of the L-shaped rod 3, a placement component is fixedly installed on the output end of the servo 5, and a projector 7 is installed inside the placement component; universal wheels are fixedly installed on the four ends of the bottom of the base plate 1, a hand-tightening bolt 4 is threaded on the upper side of the outer surface of the hollow column 2, and a plurality of through holes are opened on one side of the outer surface of the L-shaped rod 3 at equal distances from top to bottom, and the through holes are adapted to the hand-tightening bolts 4.

[0022] The universal wheels make it easy to move the projector 7 to the desired location. The L-shaped rod 3 can be moved up and down to drive the projector 7. The moved L-shaped rod 3 can then be fixed using the hand screws 4 in conjunction with the through holes, thereby fixing the height of the projector 7. The servo 5 can be controlled to rotate the placement assembly, which in turn rotates the projector 7, thereby changing the projection direction of the projector 7. Users can adjust the position, height, and projection direction of the projector 7 according to their needs, making the projector 7 highly flexible when used.

[0023] The placement assembly includes a bracket 6, the top of which is fixedly connected to the output of the servo 5. A rotating shaft 11 is rotatably mounted between the left and right sides of the bracket 6. Two lugs 9 are fixedly mounted on the outer surface of the rotating shaft 11. A placement plate 8 is fixedly mounted on the bottom of the two lugs 9. The top of the placement plate 8 has a placement slot, and the projector 7 is located within the placement slot. A stepper motor 10 is fixedly mounted on one side of the bracket 6, and the output of the stepper motor 10 is fixedly connected to one end of the rotating shaft 11.

[0024] The servo 5 can drive the bracket 6 to rotate, and the bracket 6 can drive the placement plate 8 to rotate through the ear plate 9, thereby changing the horizontal direction of the projector 7; the stepper motor 10 can drive the rotating shaft 11 to rotate, and the rotating shaft 11 can drive the placement plate 8 to rotate with the rotating shaft 11 as the axis through the ear plate 9, thereby changing the projection position of the projector 7 in the vertical direction.

[0025] The bottom of the placement plate 8 is equidistantly provided with a number of heat dissipation holes 15 . The placement plate 8 is made of metal copper. The heat dissipation holes 15 and the copper placement plate 8 can assist in heat dissipation of the projector 7 and prevent the projector 7 from being damaged by overheating.

[0027] The spring 14 can pull the clamping plate 12 to move toward the placement plate 8, and the bottom of the clamping plate 12 can contact the top of the projector 7. Under the action of the spring 14, the projector 7 is clamped and fixed inside the placement groove, so that the projector 7 will not fall off the placement plate 8 after moving or changing the projection direction.
