Abstract
The utility model provides a mini-sized projector comprising a casing, an IC, a PCB, and a mini-sized optical engine assembly. The casing is provided with a button board, which is a copper-clad laminate. The IC is connected with the button board by a conductive silicon sheet, and therefore the heat dissipation of the IC can be realized by the button board, and the heat dissipation efficiency can be improved.
Description
Technical field
The utility model relates to office equipment field, refers to especially a kind of micro projector.
Background technology
Along with the development of electronic technology, portable multimedia equipment is more and more abundanter, as digital camera, video camera, player etc., along with increasing of these equipment, therefore having more chance need to show the content of storage and share etc., and projecting apparatus is as a kind of conventional presentation device, there is plurality of advantages, and micro projector has increased the scope and the convenience that use especially, but, because projecting apparatus quantity of heat production is large, therefore be an one important problem for the heat radiation of micro projector, traditional radiating mode is at IC(integrated circuit) the upper fin that increases, this mode can meet the needs of heat radiation substantially, if but the operating time extends a little, micro projector heating is serious, be that this mode is dispelled the heat limited, on the other hand, traditional micro projector prevents that the mode of electromagnetic radiation from being to increase metallic shield, the scope that this mode shields is relatively little.
Utility model content
The utility model proposes a kind of micro projector, solved the problem of mentioning.
The technical solution of the utility model is achieved in that a kind of micro projector, comprise casing and be located at IC, pcb board and the micro optical-mechanical assembly in described casing, described casing is provided with keypad, and described keypad is copper foil plate, described IC joins by heat-conducting silica gel sheet and described keypad.
Further, have additional exposed Copper Foil on described pcb board, described Copper Foil is by posting conductive sponge and described keypad joins.
Further, described conductive sponge is placed in the top end of described pcb board.
Further, described keypad below is also provided with radiator fan.
Further, described keypad level is located at the below of described casing upper surface, and the corresponding described keypad of the upper surface place of described casing is provided with button and touch-screen.
The beneficial effects of the utility model are: thus micro projector of the present utility model is connected with described keypad by be provided with described heat-conducting silica gel sheet on described IC, utilize the characteristic of described keypad copper foil plate, dispel the heat, there is larger area of dissipation and radiating rate, thereby reach better radiating effect, and, can also carry out enhance heat by described radiator fan, and, described micro projector also utilizes described conductive sponge that the Copper Foil on described pcb board and described keypad are joined, thereby utilize the large-area copper foil plate of described keypad to shield.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the planar structure schematic diagram of an embodiment of a kind of micro projector of the utility model;
Fig. 2 is the cross section structure schematic diagram of micro projector shown in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, a kind of micro projector, comprise casing 1 and be located at IC, pcb board 2 and the micro optical-mechanical assembly in casing, casing 1 is provided with keypad 3, and keypad 3 is copper foil plate, IC joins by heat-conducting silica gel sheet and keypad 3, thereby the heat on IC can pass on keypad 3 by heat conduction film rapidly, and dispel the heat by keypad 3, improve the efficiency of heat radiation.
Further, have additional exposed Copper Foil on pcb board 2, Copper Foil is by posting conductive sponge and keypad 3 joins, this design, makes pcb board 2 and keypad 3 want to connect, thereby utilizes the large-area copper foils for shielding of keypad 3, simplified structure, and there is good shield effectiveness.
Further, conductive sponge is placed in the top end of pcb board 2, can certainly be arranged at other position.
Further, keypad 3 belows are also provided with radiator fan, thereby can further strengthen heat sinking function.
Further, keypad 3 levels are located at the below of casing 1 upper surface, and the corresponding keypad of the upper surface place of casing 1 is provided with button 4 and touch-screen 5, and button 4 and touch-screen 5 are for the control to micro projector.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
