Described mobile terminal comprises printed circuit board (PCB) 10, key switch 20, metal center 30, decoration 40, keying body 50 and elastic sheet rubber 60.
In the present embodiment, described printed circuit board (PCB) 10 in the form of sheets or strip.Described key switch 20 is fixedly installed on a side of described printed circuit board (PCB) 10, because key switch 20 uses frequently, in order to avoid key switch 20 is long make between use and cause the consequence come off, preferably adopt scolding tin to weld on the printed circuit board 10 by key switch 20, thus achieve key switch 20 firm with the connection of printed circuit board (PCB) 10.
In the present embodiment, the frame structure of described metal center 30 inner hollow, border formation main body.Normally, described metal center 30 holds main parts size such as cutting fixing touch-screen 80, display screen (not shown), printed circuit board (PCB) 10, battery (not shown), back cover 90, and described metal center 30 plays a part to support above-mentioned main parts size.Particularly, described metal center 30 has an accommodation cavity 31, and described printed circuit board (PCB) 10 and key switch 20 are arranged in described accommodation cavity 31.Described metal center 30 adopts the material such as aluminium alloy or magnesium alloy comparatively light and the material that intensity is higher usually.
Described decoration 40 is positioned on a side of described metal center 30, and described decoration 40 has the accommodation spacing hole slot 41 of the spacing keying body 50 of an accommodation.Normally, described decoration 40 is formed as a part for mobile phone appearance, and described keying body 50 is protruded from the accommodation spacing hole slot 41 of described decoration 40.
Described keying body 50 wears described accommodation spacing hole slot 41, and is limited in described decoration 40, and the position of described keying body 50 is corresponding with the position of described key switch 20.It is corresponding with the position of key switch 20 by the position of keying body 50 is arranged to, when pressing keys body 50, keying body 50 can act directly on key switch 20, thus key switch 20 is powered from battery by mainboard 10, and key switch 20 is able to work.
Described keying body 50 is positioned at the centre position of described decoration 40, by keying body 50 being arranged on the centre position of decoration 40, can prevent keying body 50 to decoration 40 certain while tilt, keying body 50 is held in decoration 40 securely.
Described elastic sheet rubber 60 is fixedly installed on a side of described metal center 30, and between described metal center 30 and keying body 50, extrudes the elastic force of described keying body 50 when described elastic sheet rubber 60 provides described keying body 50 not to be pressed.Namely, during described mobile phone horizontal positioned, distribute keying body 50, elastic sheet rubber 60, key switch 20 from inside to outside successively.In normal state, described elastic sheet rubber 60 provides elastic force keying body 50 outwards extruded.When pressing keys body 50, elastic sheet rubber 60 produces elastic deformation and forms elastic force, and elastic force is passed to key switch 20, and key switch 20 produces displacement, and then is formed with printed circuit board (PCB) 10 and be electrically connected.
What namely the elastic sheet rubber 60 in the present embodiment used those skilled in the art to commonly use have, and flexible elastomeric material is made.
Due to button 52 in the alternative soft material of the prior art of elastic sheet rubber 60 of the present embodiment
,effect, described keying body 50 adopts hard material, thus eliminates interior button 52 of the prior art
,, space is reduced, and cost reduces.And elastic sheet rubber 60 can cover the space of keying body 50 to metal center 30, thus play the effect of waterproof, owing to eliminating key support 200 of the prior art
,with sealing ring 100
,, can reduce costs further, reduce space.
In concrete enforcement, described elastic sheet rubber 60 is pasted and fixed on a side of described metal center 30 by marine glue 70.By arranging marine glue 70 between elastic sheet rubber 60 and metal center 30, waterproof effect can be improved further.In the present embodiment, described marine glue 70 adopts PE(Polyethylene; Polyethylene) glue.
In concrete enforcement, the bottom of described keying body 50 is provided with one towards the boss 51 of described elastic sheet rubber 60, and described elastic sheet rubber 60 supported by described boss 51.By arranging one in the bottom of keying body 50 towards the boss 51 of elastic sheet rubber 60, when pressing keys body 50, elastic sheet rubber 60 supported by described boss 51, the pressure of pressing keys body 50 can be passed in elastic sheet rubber 60 better, and then make elastic sheet rubber 60 produce elastic deformation.
In concrete enforcement, the week of described keying body 50, described extension 52 abutted described decoration 40 along outwardly forming a circle extension 52.In the present embodiment, by the week in keying body 50 along outwardly forming a circle extension 52, described extension 52 can be connected in decoration 40 when assembling, and can prevent keying body 50 from coming off from the accommodation spacing hole slot 41 of decoration 40.
In concrete enforcement, described elastic sheet rubber 60 comprise one towards the projection 61 of described boss 51, described protruding 61 support described boss 51.In the present embodiment, by elastic sheet rubber 60 is arranged a projection 61 on the direction of the boss 51 towards described keying body 50, and the boss 51 that described protruding 61 support keying body 50.In normal state, because protruding 61 support boss 51, when after pressing keys body 50, protruding 61 produce the elastic force of elastic deformation generation one towards boss 51, make keying body 50 return rapidly, under can preventing normal condition, keying body 50 is rocked between decoration 40 and elastic sheet rubber 60.
In concrete enforcement, the described bottom of protruding 61 is provided with a protrusion 62, and described protrusion 62 is corresponding with described key switch 20.In the present embodiment, by arranging a protrusion 62 in the bottom of the projection 61 of elastic sheet rubber 60, and protrusion 62 is relative with key switch 20, like this when pressing keys body 50, pressure can be passed to key switch 20 better by protrusion 62, pressing keys body 50 is comparatively light, promotes Consumer's Experience.
In concrete enforcement, the protrusion 62 of the boss 51 of described keying body 50, the projection 61 of described elastic sheet rubber 60, described elastic sheet rubber 60 and the center line of key switch 20 overlap.Namely, on a certain plane B paralleled with the lower planes of mobile phone, the protrusion 62 of the boss 51 of described keying body 50, the projection 61 of elastic sheet rubber 60, elastic sheet rubber 60 and the center line of key switch 20 are all in described plane B.Like this when pressing keys body 50, the pressure of pressing keys body 50 conducts to key switch 20 through the projection 61 of the boss 51 of keying body 50, elastic sheet rubber 60, the protrusion 62 of elastic sheet rubber 60 successively, make key switch 20 be easy to be pressed against like this, promote Consumer's Experience.
According to mobile terminal of the present utility model, described mobile terminal by arranging elastic sheet rubber 60 between keying body 50 and metal center 30, and described elastic sheet rubber 60 instead of the interior button 52 of soft material of the prior art
,, the effect of waterproof can be played; And owing to eliminating key support 200 of the prior art
,with sealing ring 100
,, reduce cost, make product lightening.
Although illustrate and described embodiment of the present utility model above, be understandable that, above-described embodiment is exemplary, can not be interpreted as restriction of the present utility model, those of ordinary skill in the art can change above-described embodiment when not departing from principle of the present utility model and aim, revising, replacing and modification in scope of the present utility model.
