Description

Technical Field

[0001] This application relates to the technical field of display screens, especially portable LED display screens. Background Art

[0002] An LED display screen is a flat panel display composed of small LED module panels, which is a device used to display various information such as text, images, videos, and video signals. The light-emitting color and efficiency of an LED are related to the materials and processes used to make the LED. Initially, all the lamp beads are blue, and then phosphor is added. According to different user needs, different light colors can be adjusted. The four commonly used ones are red, green, blue, and yellow. Since an LED has a low working voltage (only 1.2 - 4.0V), can emit light actively and has a certain brightness, and the brightness can be adjusted by voltage or current, and it is also resistant to impact, vibration, and has a long lifespan, there is no other display method that can rival the LED display method in large display devices.

[0003] When existing portable LED display screens are in use, in order to display or promote more information, multiple display screens are set up to achieve multi-screen linkage. However, when carrying and transporting, the overall volume of the display screen is too large, occupying a large amount of space, causing space waste, and being inconvenient for movement or storage. Moreover, the angle of the display screen is fixed, and when viewers watch, light reflection and glare will occur, affecting the viewing effect. Therefore, a portable LED display screen is proposed for the above problems. Summary of the Invention

[0004] In this embodiment, a portable LED display screen is provided to solve the problems in the prior art that when in use, in order to display or promote more information, multiple display screens are set up to achieve multi-screen linkage, but when carrying and transporting, the overall volume of the display screen is too large, occupying a large amount of space, causing space waste, being inconvenient for movement or storage, and the angle of the display screen is fixed, and when viewers watch, light reflection and glare will occur, affecting the viewing effect.

[0005] According to one aspect of the present application, a portable LED display screen is provided, including a base and a mounting frame. A moving component is arranged inside the mounting frame. The moving component includes a second motor, a second screw rod, a second display screen, and a movable plate. A second motor is fixedly installed on the mounting frame. The output shaft of the second motor extends into the interior of the mounting frame and is fixedly installed with a driving gear. The second screw rod is rotatably connected to the interior of the mounting frame through a bearing. A driven gear is fixedly installed on the second screw rod. The driving gear is meshed with the driven gear. Two movable plates are threadedly connected to the second screw rod, and two second display screens are fixedly installed on the two movable plates.

[0006] Furthermore, a first display screen is arranged on the mounting frame

[0007] Furthermore, a limit plate is fixedly installed on one side of each of the two second displays.

[0008] Furthermore, a mounting plate is fixedly installed on the base, and a mounting groove is provided on the mounting plate. A first lead screw is rotatably connected to the inside of the mounting groove through a bearing. A first motor is fixedly installed on the mounting plate, and the output shaft of the first motor extends into the inside of the mounting groove and is fixedly connected to the first lead screw. A threaded block is threadedly connected to the first lead screw.

[0009] Furthermore, a connecting bracket is fixedly installed on the threaded block, and a mounting bracket is rotatably connected to the connecting bracket.

[0010] Furthermore, an electric push rod is rotatably connected to the connecting frame, and the output end of the electric push rod is rotatably connected to the mounting frame.

[0011] Furthermore, two guide rods are fixedly installed inside the mounting groove, and both guide rods are slidably connected to the threaded block.

[0012] Furthermore, the second lead screw is provided with two sections of threads with opposite rotation directions, and the two movable plates are respectively distributed on the opposite threads.

[0013] Furthermore, a limiting rod is fixedly installed inside the mounting bracket, and both movable plates are slidably connected to the limiting rod.

[0014] Furthermore, four brake casters are fixedly installed at the bottom of the base.

[0015] Through the above embodiments of this application, by setting a moving component and starting the second motor, the two second displays can be folded or stored inside the mounting frame when not in use, thereby greatly reducing the space occupied by the display screen as a whole. By driving the output shaft of the second motor to rotate in the opposite direction, the user can easily move the two second displays from inside the mounting frame to the outside, achieving rapid deployment and greatly improving the efficiency of the display screen, enabling the user to complete the display or promotion task in a short time.

[0016] By activating the first motor, the first display screen and the two second display screens can be raised and lowered, allowing their height to be adjusted according to different usage scenarios and needs. When used outdoors, the display screens can be raised to an appropriate height so that more people can view them; when used indoors, the height of the display screens can be lowered to adapt to space limitations and the viewing angle of the audience. The first display screen and the two second display screens can achieve various combination methods, such as individual display, side-by-side display, or superimposed display, so that the display screens can meet more diverse display needs, improve information transmission efficiency, and enhance the viewing experience of the audience.

[0017] By activating the electric actuator, the output end of the electric actuator drives the mounting bracket 1 to rotate, which can adjust the tilt angle of the first and second displays. This ensures that viewers can get the best viewing effect in different positions, helps to reduce light reflection and glare, and can significantly improve the brightness and contrast of the display, especially in outdoor or brightly lit environments, making the image clearer and the colors more vibrant.
