Understand and realization the utility model for the ease of persons skilled in the art, now describe embodiment of the present utility model in conjunction with the accompanying drawings.
About aforementioned and other technology contents, characteristics and effect of the present utility model, in the following detailed description that cooperates with reference to four graphic preferred embodiments, can clearly present.Explanation by embodiment, when can being to reach technological means that predetermined purpose takes and effect to get one more deeply and concrete understanding to the utility model, yet appended graphic provides reference and explanation usefulness, is not to be used for the utility model is limited.
Before the utility model is described in detail, be noted that in the following description content similarly assembly is to represent with identical numbering.
As shown in Figures 1 and 2, be first preferred embodiment of the utility model keyboard, this keyboard 100 comprises a base plate 1, a film circuit board 2, most elastic partss 3, and a push-button unit 4.
As shown in Figures 2 and 3, film circuit board 2 is arranged at base plate 1 end face, film circuit board 2 end faces are laid with the induction contact site 21 that most each intervals are arranged, described elastic parts 3 quantity are identical with induction contact site 21 quantity, each elastic parts 3 is that rubber or silica gel material are made, and it can be fixed on film circuit board 2 end faces and be positioned at accordingly through cemented mode respectively responds to contact site 21 tops.Each elastic parts 3 comprises that one is centered around the surrounding wall 31 of respectively responding to contact site 21 outsides, an and touch part 32 that is arranged at surrounding wall 31 tops, touch part 32 can be for pushing and moving down through the distortion of surrounding wall 31, whereby, can conflict to respond to and make it produce sensor signal on the contact site 21 in touch part 32.
Push-button unit 4 comprises that one is soft materials and the button diaphragm 41 that is arranged on film circuit board 2 end faces, button diaphragm 41 is made by rubber or silica gel material, it comprises a lamellar body 411, and most the button portions 412 that are convexly set on the lamellar body 411, lamellar body 411 can see through cemented mode and be fixed on film circuit board 2 end faces.Because the quantity and the position of button portion 412 are corresponding with the quantity and the position of described elastic parts 3 respectively, therefore, when the lamellar body 411 of button diaphragm 41 was cemented at film circuit board 2 end faces, each button portion 412 can cover on each elastic parts 3 accordingly.Each button portion 412 comprises a perisporium 413 that is protruded out by lamellar body 411 up, and one be formed at perisporium 413 tops push wall 414, what each elastic parts 3 was positioned at each button portion 412 pushes wall 414 belows, when the user pushes pushing wall 414 and moving down of each button portion 412, perisporium 413 can produce distortion because of the drive of pushing wall 414, pushes touch part 32 that wall 414 can drive elastic parts 3 and moves down and conflict and respond to contact site 21.When the user discharges when pushing wall 414,, can order about and push wall 414 and reset to as shown in Figure 3 initial position by the reseting elasticity of the surrounding wall 31 of elastic parts 3 and the reseting elasticity of perisporium 413.
Preferably, push wall 414 hardness and intensity for what increase each button portion 412, and can will push wall 414 and firmly be supported on initial position, push-button unit 4 comprises that also most hard strengthen sheets 42.What each hard strengthened that sheet 42 areas are less than or equal to each button portion 412 pushes wall 414 areas, each hard reinforcement sheet 42 can be fixed on through cemented mode pushes wall 414 bottom surfaces, 32 tops, touch part of each elastic parts 3 then can be connected to each hard and strengthen sheet 42 bottom surfaces, whereby, can increase structural rigidity and the intensity push wall 414, and elastic parts 3 and hard are strengthened sheet 42 and can will be pushed wall 414 and firmly be supported on initial position.In the present embodiment, it is made by plastics or rigid material such as metal or acryl that each hard is strengthened sheet 42, and certainly, hard is strengthened the rigid material that sheet 42 also can be other kind.
Because button diaphragm 41 is a soft materials, the hard of arranging in pairs or groups is simultaneously strengthened sheet 42 and is located at the design of pushing wall 414 bottom surfaces, make the user pressing keys portion 412 push wall 414 time, the sense of touch of finger is preferable, and can reduce and understand the situation that produces finger pain after the user pushes wall 414 for a long time.Moreover, push the position that wall 414 can be positioned at elastic parts 3 tops through the support of perisporium 413, compare down with prior art, can omit scissor structure Design, make keyboard 100 comparatively simply also can reduce manufacturing cost in design.
As Fig. 4 and shown in Figure 5, it is second preferred embodiment of the utility model keyboard, the one-piece construction of this keyboard 110 is identical with first preferred embodiment, it is to be fixed on through cemented mode respectively to push wall 414 end faces that difference is in each hard reinforcement sheet 42, whereby, can increase the structural rigidity and the intensity of pushing wall 414 equally.
As Fig. 6, Fig. 7 and shown in Figure 8, it is the 3rd preferred embodiment of the utility model keyboard, the one-piece construction of this keyboard 120 is identical with first preferred embodiment, and difference is in keyboard 120 and also comprises a support frame 5 that is arranged at 2 of the lamellar body 411 of button diaphragm 41 and film circuit boards.
As Fig. 9 and shown in Figure 10, it is the 4th preferred embodiment of the utility model keyboard, the one-piece construction of this keyboard 130 is identical with the 3rd preferred embodiment, it is to be fixed on through cemented mode respectively to push wall 414 end faces that difference is in each hard reinforcement sheet 42, whereby, can increase the structural rigidity and the intensity of pushing wall 414 equally.
Conclude above-mentionedly, the keyboard 100,110,120,130 of each embodiment is strengthened the design that sheet 42 engages by the hard of the button diaphragm 41 of soft materials and rigid material, can increase the structural rigidity and the intensity of pushing wall 414.Moreover, see through hard and strengthen the design of pushing wall 414 bottom surfaces that sheet 42 is cemented at button diaphragm 41, make the user pressing keys portion 412 push wall 414 time, the sense of touch of finger is preferable, and can reduce the user and push the situation that can produce finger pain behind the wall 414 for a long time.In addition, push that wall 414 can see through the support of perisporium 413 and the position that be positioned at elastic parts 3 tops, can omit scissor structure Design, make keyboard 100,110,120,130 comparatively simply also can reduce manufacturing cost in design, can reach the purpose of the utility model institute demand really.
Though described the utility model by embodiment, but those of ordinary skills know, under the situation that does not break away from spirit of the present utility model and essence, just can make the utility model that many distortion and variation are arranged, scope of the present utility model is limited to the appended claims.
