Abstract
The invention provides a forming guide pillar applied to a light guide plate. The forming guide pillar of the invention comprises a light guide plate, a guide pillar, keys arranged at the upper part of the light guide plate and switches arranged at the lower part of the light guide plate; the lower part of each key is provided with a guide pillar correspondingly; the position of each guide pillar is corresponding to a switch. The guide pillar of the invention is characterized in that the guide pillar is combined on the bottom of the light guide plate in the way of UV glue forming, and has the advantages that the guide pillar is combined on the bottom of the light guide plate in the way of UV glue forming, causing the total thickness of the light guide plate and the guide pillar to be reduced; therefore, the problem of bad pressing hand feeling caused by adding the light guide plate to the key structure can be solved, and the forming guide pillar of the invention is also applicable to relatively thin mobile phones and can be manufactured according to requirements.
Description
Technical field
The present invention relates to a kind of architecture advances of mobile phone key module, particularly a kind of light guide plate moulding guide pillar.
Background technology
In mobile phones design, distinguish each function key of mobile phone and shown content for making it at night and dark place, lighting device need be installed.
Lighting device adopts the LED lamp, adopts in the mode of some button is thrown light on.But need to use a large amount of LED lamps be evenly distributed on each orientation of keyboard, could guarantee that keyboard is luminous even and briliancy is high everywhere, make that LED lamp usage quantity is too much.Therefore can cause the cell phone standby time short because of thereby needs consume the operating time that lot of energy has reduced battery greatly, LED lamp usage quantity too much also can increase production cost simultaneously, takies the mobile phone inner space.
Above-mentioned mobile phone key module as shown in Figure 1, comprise button 3 ' from top to bottom, be provided with guide pillar plate 20 ', metal clips 5 ', switch 4 ', the pcb board 6 ' of guide pillar 2 ', pcb board 6 ' is provided with LED lamp 7 ', guide pillar plate 20 ' the corresponding position of each button 3 ' below is provided with a guide pillar 2 ', each the corresponding metal clips 5 ' in guide pillar 2 ' below and switch 4 '.
For addressing the above problem, between the guide pillar plate is with metal clips, increased light guide plate, structure comprises button 3 as shown in Figure 2 from top to bottom ", be provided with guide pillar 2 " guide pillar plate 20 ", light guide plate 1 ", metal clips 5 " and switch 4 ", pcb board 6 ", pcb board 6 " be provided with LED lamp 7 ".Light guide plate 1 " can be with LED lamp 7 " light that sends reflects, and makes mobile phone key 3 " obtained uniform backlight, and can save the consumption of LED lamp original over half.But increase light guide plate 1 " after, can seriously influence button 3 " feel of pushing, this problem is perplexing the designer of mobile phone button always.
In being the patent of 200620139098.X, the patent No. disclosed a kind of mobile phone key module, be provided with rubber mass elastic layer 80, as shown in Figure 3, light-leading film 100 is bonded in elastic layer 80 upper surfaces, light-leading film 100 tops are provided with button 30, elastic layer 80 bottoms have a plurality of protruding 800, each projection 800 corresponding corresponding switches 400 (or metal clips).But elastic layer adopts elastomeric material to make, and quality is softer, pushes feel not as the harder guide pillar of quality, and elastic layer is difficult for producing as required and corresponding accurate position of switch and size.If simply change the projection of elastic layer into guide pillar, guide pillar will have certain thickness just can be made, and mobile phone is not easy to do thin.
Summary of the invention
The invention provides a kind of light guide plate moulding guide pillar, purpose is to solve the prior art problem, provides a kind of light guide plate and guide pillar to combine, and has improved button and has pushed feel, and be applicable to thin mobile phone, can make the light guide plate moulding guide pillar of required size and position as required.
The present invention's technical scheme that adopts of dealing with problems is:
Light guide plate moulding guide pillar comprises light guide plate, guide pillar, the light guide plate top is provided with button, and the light guide plate below is provided with switch, and each button below correspondence is provided with guide pillar, each guide pillar position is corresponding to separately switch, and it is characterized in that: described guide pillar is combined in bottom surface of light guide plate in the mode of UV glue moulding.
Described light guide plate is that transparent plastic material is made.
Also be provided with metal clips between described switch and the guide pillar.
The method of light guide plate moulding guide pillar is characterized in that:
(1) UV glue is poured in the mould with shrinkage pool, and the shrinkage pool of mould is filled up;
(2) light guide plate is placed on the mould;
(3) place it in irradiation a period of time under the UV light, make the UV glue curing in the mould, and attached on the light guide plate;
(4) mould is separated with light guide plate.
In the above-mentioned technology, UV rayed energy is 1000-1600mj; The UV rayed time is 6-10s.
Beneficial effect of the present invention: guide pillar combines with light guide plate by UV glue molding mode, the gross thickness of light guide plate and guide pillar is reduced, not only solved and increased the bad problem of feel of pushing that causes after the light guide plate in the press-key structure, also be applicable to thin mobile phone, and can make as required.

Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 4, the present invention includes the light guide plate 1 that transparent plastic material is made, guide pillar 2 is combined in light guide plate 1 below for UV glue with the ultraviolet irradiation molding mode, light guide plate 1 top is provided with 3 buttons 3, light guide plate 1 below is provided with switch 4, and each button 3 below correspondence position is provided with guide pillar 2, and each button 3 position is corresponding to separately switch 4, obviously each guide pillar 2 position is provided with metal clips 5 corresponding to separately switch 4 between switch 4 and the guide pillar 2.
Switch 4, metal clips 5 all are arranged on the PBC plate 6 in the present embodiment, also are provided with LED lamp 7 on the PBC plate 6.In other embodiments, the LED lamp can be arranged on the side of light guide plate, and switch, metal clips also can be arranged on the carrier that other suitable prior aries adopt.
The effect of metal clips 5 be make button 3 can be after pushing touch switch 4 reliable reset again, if light guide plate 1 elasticity enough or in addition is provided with the button resetting means metal clips 5 can be set.
Also secure bond is in light guide plate 1 bottom surface for UV glue is made for described guide pillar 2, and its method with the moulding of following UV glue is combined in bottom surface of light guide plate.
