The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, the positioner of backlight module of the present invention, comprises substrate 1, the first location-plate 2 and the second location-plate 3; Described the first location-plate 2 and described the second location-plate 3 are arranged on described substrate 1, described the first location-plate 2 and described the second location-plate 3 have respectively right angle draw-in groove, the position of the right angle draw-in groove of described the first location-plate on described substrate 1 is relatively fixing, the position of the right angle draw-in groove of described the second location-plate on described substrate 1 can regulate, the right angle draw-in groove of the right angle draw-in groove of described the first location-plate 2 and described the second location-plate 3 is oppositely arranged, and forms the draw-in groove space 4 of location backlight module.
The first location-plate 2 described in the present embodiment and described the second location-plate 3 comprise respectively minor face 22,32 and long limit 21,31, the minor face 22 of described the first location-plate and long limit 21 surround the right angle draw-in groove of described the first location-plate, the minor face 32 of described the second location-plate and long limit 31 surround the right angle draw-in groove of described the second location-plate, the minor face 22 of described the first location-plate and the minor face 32 of described the second location-plate are oppositely arranged, and the long limit 21 of described the first location-plate and the long limit 31 of described the second location-plate are oppositely arranged.Two rectangular card grooves of the first location-plate and the second location-plate form the draw-in groove space (in figure shown in rectangular broken line) of location backlight modules, and backlight module is put into draw-in groove space and can be located.The present embodiment is for the consideration of cost-saving and aspect simple in structure, the first location-plate 2 of positioner and the second location-plate 3 are set to only minor face and long limit, consist of, the structure that it should be noted that the first location-plate 2 and the second location-plate 3 is not limited to this, also can adopt other version to replace.
The long limit 21 of described the first location-plate is fixed on described substrate 1, and the minor face 22 of described the first location-plate can be along the transverse shifting (direction of arrow in Fig. 1) on described substrate 1 surface; The minor face 32 of described the second location-plate is fixed on described substrate 1, and the long limit 31 of described the second location-plate can be along vertically move (direction of arrow in Fig. 1) on described substrate 1 surface.The first location-plate must have one relative to another, can move with minor face or long limit in the second location-plate, so can meet the different FPC(flexible PCBs of backlight) outlet design, as for minor face is set, still can moves and can change according to actual conditions relative to substrate surface in long limit.
Fig. 2 is the structural representation of the substrate of the embodiment of the present invention.With reference to Fig. 2, on substrate 1, there is the gathering sill 12 along its surperficial horizontally set, gathering sill 13 and the size regulating tank 11 arranging along its surface longitudinal, the minor face 22 of gathering sill 12 and the first location-plate matches, the minor face 22 of the first location-plate is arranged in gathering sill 12 and can slides along the direction of gathering sill 12, to regulate the exit position of backlight FPC top.In like manner, the long limit 31 of gathering sill 13 and the second location-plate matches, and the long limit 31 of the second location-plate is arranged in gathering sill 13 and can slides along the direction of gathering sill 13, to regulate right-hand exit position of backlight FPC.
It should be noted that and above-mentionedly only enumerated the portable plate 22 of the first location-plate and the portable plate 31 of the second location-plate is assemblied in the form that the gathering sill 12,13 on substrate slides, yet the portable plate 22 of the first location-plate and the move mode of the portable plate 31 of the second location-plate on substrate are not limited to this, also can adopt other forms to substitute, for example in the bottom surface of the portable plate 22 of the first location-plate and the portable plate 31 of the second location-plate, pulley is set, track etc. is set on substrate.
Shown in Fig. 3 and 4, the bottom surface of the second location-plate 3 is provided with lead 33, lead 33 matches with size regulating tank 11, the second location-plate 3 integral installations are fitted in regulating tank 11, and the second location-plate 3 can move along size regulating tank 11 under the effect of driving mechanism (not shown), to zoom in or out the draw-in groove space of backlight module.In the present embodiment, enumerated three size regulating tanks 11 have been set on substrate 1, the scheme of three leads 33 corresponding with three size regulating tanks is set on the second location-plate 3, yet the quantity of the lead 33 arranging on the quantity of the regulating tank 11 arranging on 1 on substrate and the second location-plate is not limited to three, and its quantity can change according to actual needs.And the form that the structure that the second location-plate 3 can move relative to described the first location-plate 2 is not limited to lead as above and regulating tank 11, also can adopt other forms to substitute, for example in the bottom surface of the second location-plate 3, pulley is set, track etc. is set on substrate.Wherein, driving mechanism can adopt the type of drive such as mechanical spring, electromagnetism or cylinder.
The position of the right angle draw-in groove of the first location-plate on substrate is relatively fixing in embodiments of the present invention, the position of the right angle draw-in groove of the second location-plate on substrate is adjustable, when being positioned, only the right angle draw-in groove of one jiao of corresponding first location-plate of backlight module need to be placed backlight module, and then the position of the right angle draw-in groove of adjusting the second location-plate, the right angle draw-in groove of corresponding the second location-plate in another angle of backlight module is placed, for the ease of automatic fine adjustment location, on the positioner of described backlight module, can also arrange and judge whether backlight module is positioned at induction mechanism or the Grating Mechanism (not shown) in the right angle draw-in groove of described the first location-plate and the right angle draw-in groove of described the second location-plate.When one jiao of backlight module is arranged in the right angle draw-in groove of the first location-plate, induction mechanism or Grating Mechanism feedback one signal being in place, and control the draw-in groove position, right angle that driving mechanism regulates the second location-plate; When another angle of backlight module is also arranged in the right angle draw-in groove of the first location-plate, induction mechanism or Grating Mechanism feedback one signal of having located, the location that completes backlight module, easy to operate, long-time use is also not easy to damage.
Finally should be noted that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from the spiritual scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
