Abstract
The utility model relates to a miniature projection computer. A master control module is connected with a projection system through a flexible PCB (Printed Circuit Board); the circuit connection of the master control module is as follows: a central processor is connected with a flash memory module, a WIFI (Wireless Fidelity) network module, a memory module, a mouse control module, a video format conversion module, a power switching module, a USB (Universal Serial Bus) interface, an HDMI (High Definition Multimedia Interface) input interface, a VGA (Video Graphics Array) input interface, a network interface RJ45 (Registered Jack 45), a direct-current (DC) power input interface, an audio output interface, an AV (Audio/Video) input interface and a SD (Secure Digital) card slot respectively, and the DC power input interface is connected with the power switching module; the circuit connection of the projection system is as follows: a DMD (Digital Micromirror Device) control module is connected with a DMD drive module and an optical lens with a circuit respectively, an LED (Light Emitting Diode) drive module is connected with an LED light source, and the LED light source produces images through the optical lens; and a miniature cooling fan is arranged in a shell. The miniature projection computer has the positive effects that the miniature projection computer has the function of a computer while the display function of a projector is realized, and the trouble caused by the fact that a portable computer is required for being connected with the projector or lecture files are required for being copied to the computer when the computer and the projector are used independently in the prior art is solved.
Description
Technical field
The utility model relates to a kind of projection arrangement, particularly a kind of micro projection computer with computer function.
Background technology
In information age today, multimedia equipment is widely used in meeting speech, research and teaching, commercial activity and home entertaining.Multimedia commonly used is that computer and projector are the branch body structure, and computer is made as the center, and projector is as screen display, and computer and projector are separate equipment.Its defective is: in practical application, often have only independent equipment in user's hand, or two kinds of equipment do not match, can't be connected in one, use difficulty and cause, and two kinds of equal prices of equipment are expensive.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of micro projection computer, can solve in micro projector, to be integrated with computer function and projector becomes one, and makes operation more simple and practical, carries flexible, and cheap.
The utility model is for realizing above-mentioned purpose; The technical scheme that is adopted is: a kind of micro projection computer; It is characterized in that: comprise the projection computer shell and be arranged on mousebutton, contact control mouse plate, keyboard, camera lens focusing knob, USB interface, HDMI input interface, VGA input interface, RJ45 network interface, direct supply input interface, audio output interface, AV input interface and the SD card slot on the projection computer shell; Also comprise the main control module, the optical projection system that are arranged on the projection computer enclosure; Said main control module is connected with optical projection system through the flexible PCB plate, and said mousebutton, contact control mouse plate and keyboard are connected with the main control module respectively; The circuit of said main control module is connected to: central processing unit is connected with SD card slot with flash memory module, WIFI mixed-media network modules mixed-media, memory modules, mouse control module, video format conversion module, power supply handover module, USB interface, HDMI input interface, VGA input interface, RJ45 network interface, direct supply input interface, audio output interface, AV input interface respectively, and the direct supply input interface is connected with the power supply handover module; The circuit of said optical projection system is connected to: the DMD control module is connected with the optical lens that is provided with circuit with the DMD driver module respectively, and the LED driver module is connected with led light source, and led light source produces image through optical lens; Miniature radiator fan setting in the enclosure.
Advantage of the utility model and good effect: (1) the utility model is that the optical projection system with main control module and projector is designed to one, has both computer function when can realize the Presentation Function of projector, is equivalent to a giant-screen portable computer.The speaker only need carry the micro projector bigger slightly than mobile phone can accomplish multimedia speech, solved tradition the two when independently using, also need portable computer be connected projector or copy the trouble of speech file to computer; (2) the utility model is a kind of micro projection computer, and advantages of small volume is 220X180X55mm, and the external power supply power supply gets final product operate as normal, and cheap.

Embodiment
Like Fig. 1, shown in 2; A kind of micro projection computer; Comprise the projection computer shell and be arranged on mousebutton, contact control mouse plate, keyboard, camera lens focusing knob, USB interface, HDMI input interface, VGA input interface, RJ45 network interface, direct supply input interface, audio output interface, AV input interface and the SD card slot on the projection computer shell; Also comprise the main control module, the optical projection system that are arranged on the projection computer enclosure; The main control module is connected with optical projection system through the flexible PCB plate, and mousebutton, contact control mouse plate and keyboard are connected with the main control module respectively; The circuit of main control module is connected to: central processing unit is connected with SD card slot with flash memory module, WIFI mixed-media network modules mixed-media, memory modules, mouse control module, video format conversion module, power supply handover module, USB interface, HDMI input interface, VGA input interface, RJ45 network interface, direct supply input interface, audio output interface, AV input interface respectively, and the direct supply input interface is connected with the power supply handover module; The circuit of optical projection system is connected to: the DMD control module is connected with the optical lens that is provided with circuit with the DMD driver module respectively; The LED driver module is connected with led light source; The light that led light source produces is up to the generation image through optical lens again through optical channel, the focal length of camera lens focusing knob adjustment optical lens; Miniature radiator fan is installed in the enclosure.
Principle of work:
Central processing unit uses the TCC89XARM11 processor, mainly is responsible for the various data operations of complete machine and handles and control; Flash memory module is responsible for the storage of various data, is equivalent to the hard disk in the computing machine; The WIFI mixed-media network modules mixed-media is responsible for the IEEE802.1b/g/n network communication; Memory modules is responsible for the interim storage of various data, is equivalent to the internal memory in the computing machine;
The vision signal of central processing unit output is connected with RTD2662 video format conversion module; Support HDMI, VGA, the input of AV signal simultaneously; Through the decoded form of video format conversion module RT2662 is the RGB888 form; This form is the form of DMD driver module requirement, thereby can the vision signal of this form be sent to optical projection system through the flexible PCB plate, projects in the screen at last.The led light source of three colors of configuration red, green, blue in the optical projection system, light source makes directional light get into the DMD device through optical module.DMD is the precise information exchange is carried out in a realization to the micro mirror group of based semiconductor a device.Each reflecting optics can both be propagated through reflection the light of injecting among the DMD.Thereby on screen, make the utility model when having the Projection Display function, have both has commercial affairs to the lens set reflection entering optical lens among the led light source process DMD with image projection, amusement, and functions such as online are equivalent to a giant-screen portable computer.
