Embodiment
For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing, the content that execution mode is mentioned is not to restriction of the present utility model.See Fig. 1 to Fig. 4, below in conjunction with accompanying drawing, the utility model is described in detail.
The partiality press keys structure of a kind of ultra-thin homogeneous printing opacity provided by the utility model, include key panel 1 and loading plate 2, described key panel 1 is fastened on the top of loading plate 2; Light guide plate 3, button 4 and luminous element 5 are installed between described key panel 1 and loading plate 2, described light guide plate 3 includes light guide section 31, press section 32 and by support portion 33 unsettled for light guide section 31, one end of described support portion 33 is fixed on loading plate 2, the other end of support portion 33 is connected to the side of light guide section 31, and press section 32 is connected to the opposite side of light guide section 31; Described luminous element 5 is fixedly installed on the loading plate 2 immediately below light guide section 31, and described button 4 is fixedly installed on the loading plate 2 immediately below press section 32, and is provided with between button 4 and press section 32, between light guide section 31 and luminous element 5 and presses gap.The fixed position of the good luminous element 5 of preset in advance and button 6 on described loading plate 2, is convenient to fixed installation.Described support portion 33 is the fulcrum of light guide section 31, makes described luminous element 5 be positioned at the center of light guide section 31 transmission region, makes press section 32 be positioned at directly over button 6 simultaneously.When pressing the outer surface directly over light guide plate 3 with hand, press section 32 touches the salient point of button 6 downwards, thus shake-up button 6 normally works; Luminous element 5 is fixedly installed on immediately below light guide section 31, and does the process of solarization line to the bottom surface of light guide section, makes uniform light illuminate light guide section 31, thus reaches the uniform-light transmission effect when outer surface is seen.Press-key structure eccentric setting of the present utility model, takies height space and area is little, makes this light guide key structure fabrication become extra-thin; And light guide structure is simple, is applicable to the button that each field needs printing opacity.
In the utility model, the bottom of described light guide section 31 is arranged with the crashproof cavity 6 preventing from colliding luminous element 5.Described luminous element 5 is fixedly installed on immediately below light guide section 31, therefore the installing space remaining in advance installing luminous element 5 is needed when lightguide plate fixing 3, described luminous element 5 is preferably set to LED, LED has certain height, in the bottom of light guide section 31, crashproof cavity 6 is set, light guide section 31 can be avoided to press down in process on the one hand and touch LED top, effectively can reduce taking height thus reaching ultra-thin of whole press-key structure on the other hand.
In the utility model, described light guide section 31, press section 32 and support portion 33 are one-body molded, and structural design is simple and production technology is simple, and suitable batch is produced, and lowers production cost; As shown in Figure 3, as the first embodiment, the top of described light guide section 31 abuts with the bottom surface of key panel 1.The region of the corresponding light guide section 31 of described key panel 1 can move downward in pressing situation, and key panel 1 pair of light guide section 31 applies downward stress, and press section 32 touches the salient point of button 6 downwards, thus shake-up button 6 normally works.
Further, as shown in Figure 4 as another embodiment, the top of described light guide section 31 is provided with lug boss 34, and this lug boss 34 is one-body molded with light guide section 31; Described key panel 1 is provided with the through hole suitable with lug boss 34, and described lug boss 34 penetrates in through hole.When pressing with hand, being directly pressed into the top of lug boss 34, namely directly downward stress being applied to light guide section 31, make press section 32 touch the salient point of button 6 downwards, thus shake-up button 6 normally works.
Preferably, the outer surface of described light guide section 31 is coated with light shield layer (not marking in the drawings), and the top area corresponding with luminous element 5 is provided with transmission region.When luminous element 5 is bright, light is launched from keying body by the transmission region of light guide section 31, display be light guide section 31 transmission region shape light, only have the region needing printing opacity could printing opacity.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
