Abstract
The utility model discloses a frame used for an interactive electronic whiteboard, which belongs to the technical field of whiteboard design and manufacture of interactive electronic whiteboards. The frame used for the interactive electronic whiteboard is arranged on the edge of a panel of the whiteboard; and the cross section of the frame used for the interactive electronic whiteboard comprises a depression matched with the edge of the panel; the opening part of the edge of the inner surface of the depression, on the same side surface with the front surface of the panel, is a plane which extends to one side where the front surface of the panel coated by a frame is positioned, is vertical to the surface of the panel, and is used for mounting a strip reflective film. The technical scheme of the frame used for the interactive electronic whiteboard not only can be used for the electronic whiteboards of orthographic projection screens, but also can be used for flat-panel displays like back projection, plasma, liquid crystal display, etc. as the electronic whiteboards of display devices. The frame used for the interactive electronic whiteboard can mount strip reflective films close to the surface of the whiteboard, thus effectively reducing touching height, better meeting the writing and operating habits of users, and providing more convenience for the users.
Description
Technical field
The present invention relates to a kind of structure of frame, belong to computer display apparatus manufacturing technology field, particularly use imageing sensor as the employed blank design and manufacturing technology of the interactive electric whiteboard of sensing element field.
Background technology
Be used to impart knowledge to students, the interactive electric whiteboard of conference system more and more is widely used, wherein use imageing sensor (being commonly called as camera) more than two, utilize that image processing techniques makes up, utilize projection screen also to begin to be employed as the interactive electric whiteboard of display surface.The basic structure of this blank as shown in Figure 1, general use two to be installed on the imageing sensor and the infrared illumination source 101 in two adjacent bights of blank, and the strip reflective membrane 105 that is installed in blank framework 104 inboards is the basic comprising element by support 102.But shown in the frame part cross sectional representation A-A of Fig. 2, the existing edge that is used to wrap up the groove 201 of the framework 104 that supports blank panel 103, be positioned at blank front (manipulating face) 204 1 sides, all have a certain thickness flange 202, be used to wrap the plate face of blank, be only the plane 203 that reflective membrane 105 is installed again outward.Because this projection 202 has certain thickness, general 1～2mm, so cause the reflective membrane can not be to greatest extent near the plate face of blank, make the touch height of blank by extra lifting the thickness of this flange.And for electronic whiteboard, touch lowly highly more, and meet user's the custom of writing or operating more, be not easy to occur connecting pen, maloperation such as dilatory more, the lifting that therefore touches height will put to no little inconvenience to the user.
In the electronic whiteboard industry, the surface that is used for the manufactured goods of display image generally all is called the panel of blank, comprises projection screen, the large-scale LCD of hard, the display screen and the cover glass plate thereof of plasma panel display.
Summary of the invention
Purpose of the present invention is exactly the shortcoming at prior art, and a kind of frame that can reduce the operation height of the interactive electric whiteboard that utilizes dual camera and image processing techniques structure to greatest extent is provided.
For achieving the above object, the utility model provides a kind of frame of edge of the panel that is installed in interactive electric whiteboard, include a depression that matches, is used to hold the edge of blank panel with panel, characteristics are on the xsect of frame, the front face surface of described depression and described panel is a plane to the extension of the positive place of the panel that is wrapped up by described frame one side at the opening part at the edge of the inside surface of same side; Described plane is perpendicular with panel surface after installing panel.
Further, if the front of described depression and described panel in the inner wall surface of same side, parallels with the front face surface of described panel, the plane of so described extension is also perpendicular with the side of the inwall of described depression.
Here frame can use aluminium section bar or the manufacturing of macromolecule plastic material.For the blank panel of the front projection screen that is used as projector, panel is generally a thin plate.At this moment for ease of frame is fixed on the panel, depression can be the groove that matches with described plate thickness, has the mounting screw hole of leading in the described groove on the frame.
The benefit of invention: adopt technique scheme, the mounted on surface that the reflectance coating of strip can be close to blank, can reduce touching height 1～2mm effectively, more meet daily the writing and operating habit of user, therefore will provide bigger ease of use for the user.
Description of drawings
Fig. 1: the existing structural representation that uses dual camera to utilize the interactive electric whiteboard of image processing techniques structure;
Fig. 2: the part synoptic diagram of the cross section, A-A of frame shown in Figure 1;
Fig. 3: the synoptic diagram of the part of the cross section, A-A of the utility model frame.
Embodiment
Fig. 3 is the utility model when being applied to electronic whiteboard as projection screen, the part synoptic diagram of a kind of A-A xsect of framework.Because the structure of other parts of framework, parts such as appearance profile as xsect, all irrelevant with purpose of the present invention, so only provided among Fig. 2 and Fig. 3 relevant depression 201, the installation site of edge in depression of flange 202, reflection bar installed surface 203 and blank panel, so be called the part synoptic diagram.Among the present invention, described depression can be a groove, its opening size and thickness fit as the panel of the blank of projector's front projection screen.Comparison diagram 2 and Fig. 3, its difference has been to remove among the present invention the flange 202 at the slot opening place, front of blank panel.Like this, the front face surface 204 of groove and blank panel is a plane 203 of extending to the positive place of the panel of blank one side at the opening part at the edge of same side, is used to install strip reflectance coating 105.Regardless of the mounting structure between groove and the blank panel, as long as described plane is perpendicular with panel surface after installing panel, the strip reflectance coating can support camera to be implemented in the purpose of whiteboard surface senses touch thing.
If as shown in Figure 3, groove (or the depression) side of 201 inwalls parallels with the surface of blank panel, and the plane 203 of so described extension is also perpendicular with the side of the inwall of described groove.
In the utility model, described frame can use aluminium section bar or macromolecule plastic material to use the mould manufacturing, and simplified manufacturing technique is enhanced productivity greatly.If be used for the electronic whiteboard of projection screen,, can also have the screw hole (not drawing among the figure) that leads to described inside grooves on the frame for ease of frame being fixed on the blank panel.
Basic scheme of the present invention can also be used for the electronic whiteboard of flat-panel monitors such as rear-projection projection, plasma, LCD as display device.If use flat-panel monitor as display device, then be positioned at the structure of whiteboard surface plate back on the frame xsect, perhaps can omit and alternative cooperation or fixed form with other, perhaps should make adaptive change according to the display panel of flat-panel monitor or the concrete structure of display itself, for example described groove 201 becomes the depression that only matches with the front of display panel etc., if can guarantee to install on the frame reflectance coating 105 plane 203 can with the front face surface 204 of display panel according to the structure of the present invention installation that matches.
