Description

Technical Field

[0001] The utility model belongs to the technical field of projection, in particular to a multi-display projector with a cloud platform. Background Art

[0002] A projector is a device that projects images or videos onto a screen. It can connect to computers, VCDs, DVDs, BDs, game consoles, DVs, and other devices through various interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools, and entertainment venues. Currently, LCD projectors on the market are all single-display and have limited projection angles. This makes text operations and wide-angle projections extremely inconvenient, resulting in a poor user experience. Furthermore, the need for additional audio input is extremely inconvenient. Therefore, a new solution is urgently needed to address these issues. Utility Model Content

[0003] The problem to be solved by the present invention is how to provide a projector which can change the projection angle and has a secondary screen display.

[0004] A multi-display projector with a pan-tilt head comprises a projector body, a pan-tilt head and a speaker;

[0005] The projector body is hinged on the pan / tilt platform via a rotating shaft;

[0006] At least one display sub-screen is provided on the projector body;

[0007] The speaker is arranged on the pan-tilt platform.

[0008] The pan / tilt platform has a cavity, and the speaker is arranged in the cavity.

[0009] The speaker is a large sound cavity speaker.

[0010] The size of the display sub-screen is 1 inch to 20 inches.

[0011] A control mainboard and a projection lens are arranged in the projector body, and the control mainboard is used to control the projection lens and the display sub-screen.

[0012] The backlight system of the display sub-screen is an LED backlight flat panel module.

[0013] The beneficial effects of this application are: the projector body can rotate 360 ​​degrees via a hinge, allowing different projection directions to be adjusted as needed. The internal space of the gimbal can be designed with a large sound cavity to improve the user experience. The display sub-screen is placed outside the projector body for direct viewing and operation by the user. The large sound cavity can enhance the reverberation effect, making the sound more immersive.

[0016] Hereinafter, the embodiments of the present application will be described with reference to the accompanying drawings. In the following description, the same modules are represented by the same reference numerals. In the case of the same reference numerals, their names and functions are also the same. Therefore, their detailed description will not be repeated.

[0017] In order to make the purpose, technical solutions and advantages of this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and do not constitute a limitation of this application.

[0018] A multi-display projector with a pan-tilt system, such as Figure 1-Figure 2 As shown: including a projector body 100, a pan / tilt head 1 and a speaker 4;

[0019] The projector body 100 is hinged to the pan / tilt head 1 via a rotating shaft 3;

[0020] At least one display sub-screen 2 is provided on the projector body 100;

[0021] The speaker 4 is arranged on the pan / tilt platform 1 .

[0022] The pan / tilt platform 1 has a cavity, and the speaker 4 is arranged in the cavity.

[0023] The speaker 4 is a large sound cavity speaker.

[0024] The size of the display sub-screen 2 is 1 inch to 20 inches.

[0025] A control mainboard and a projection lens 5 are provided in the projector body 100 . The control mainboard is used to control the projection lens 5 and the display sub-screen 2 .

[0026] The backlight system of the display sub-screen 2 is an LED backlight flat panel module.

[0027] The pan-tilt head 1 supports the projector body 100, which can rotate 360° via a hinge 3. The interior of the pan-tilt head 1 can be designed as a large sound chamber, enhancing the user experience. The secondary display screen 2 is placed outside the projector body 100 for direct viewing and operation by the user, serving as the projector's secondary display. The hinge 3 connects the pan-tilt head 1 and projector body 100 via screws and can be made of plastic or metal. This large sound chamber enhances the reverberation effect, making the sound immersive. The projection lens 5 magnifies the internal display and projects it onto a receiving surface. The projection angle can be adjusted using the pan-tilt head, and the projected image serves as the projector's primary display. The secondary display screen 2 can be touch-sensitive or non-touch-sensitive. The control board controls the secondary display screen 2 and projection lens 5 via FPS signals, allowing simultaneous display or switching between separate, independent display interfaces. The secondary display screen 2's backlight system uses an LED backlight flat-panel module. This backlight system can be turned on and off at any time, adapting to the needs and functions of various projection environments.
