[0002] After searching, application number 201921333778.9 discloses a multi-angle rotating LED transparent screen, including a transparent screen body, a device base and a telescopic support rod, the bottom of the transparent screen body is fixedly connected to the telescopic support rod, the bottom of the telescopic support rod is fixedly connected to the device base, one side of the device base is fixedly connected to a power interface, the inner middle part of the device base is fixedly connected to a motor fixing groove, the top of the motor fixing groove is fixedly connected to a servo motor, and the bottom of the device base is fixedly connected to an adjustable support.

[0003] During use, a multi-angle rotating LED transparent screen in this patent application controls the rotation angle and rotation speed of the servo motor through a controller, so that the transparent screen body can rotate at different rotation angles and rotation speeds, so that the transparent screen body can complete different working purposes, and then the motor is controlled by the controller to drive the silent cooling fan to rotate, thereby driving the air flow near the silent cooling fan, thereby cooling the device body. However, during such use, since the position of the silent cooling fan on the base of the device is fixed, when the transparent screen body is adjusted and rotated to different positions, the position of the transparent screen body and the silent cooling fan will be staggered, and the silent cooling fan will not be able to effectively dissipate heat for the transparent screen body, reducing the practicality of the device. For this reason, we propose a multi-angle rotating LED transparent screen. Utility Model Content
