Abstract
For a pressing structure for keyboard, be made up of two pieces of runing rests arranged in a crossed manner, runing rest comprises linkage section and is separately positioned on stiff end and the link at linkage section two ends; Wherein stiff end is connected with keyboard pcb; Keycap is connected on link; Salient point is provided with towards the side of keyboard pcb at linkage section; The linkage section of two pieces of runing rests intersects mutually, and two salient point laminatings on two pieces of linkage sections form circular contact, for pressing the resilient contact switch on keyboard pcb.The lever that the utility model intersects placement stainless steel runing rest formation two ends after utilizing two bendings balance, utilize the resilient contact switch on the boss point promotion circuit board in the middle part of stainless steel runing rest back segment, make circuit by tactile conducting, the thickness of pressing structure is little, when the resilient contact switch of use 0.2 millimeter ~ 0.4 millimeter of stroke, the stroke of pressing structure can reduce to 0.5 millimeter ~ 0.9 millimeter, thus greatly reduces the thickness of keyboard.
Description
Technical field
The utility model relates to electricity field, particularly keyboard, particularly a kind of pressing structure for keyboard.
Background technology
Keyboard is a kind of instruction and data input unit run for operating equipment, also refers to the one group of function key (as typewriter, computor-keyboard) operating a machine or equipment through system arrangement.Keyboard is also a part for composition keyboard instrument, and also can refer to the musical instrument using keyboard, as piano, numerical digit piano or electronic organ etc., keyboard contributes to practicing at typing.Keyboard is the most frequently used is also topmost input equipment, can be input in computer by English alphabet, numeral, punctuation mark etc. by keyboard, thus gives an order to computer, inputs data etc.
But in prior art, various control panel and notebook computer using keyboard as input unit.But the more space of keyboard grabbing, makes control panel and notebook computer be difficult to more frivolous, cannot satisfy the demands of consumers.Meanwhile, the keyboard life-span is more limited, and cost is high.
Utility model content
The purpose of this utility model is to provide a kind of pressing structure for keyboard solving the technical problem in the more space of keyboard grabbing in prior art.
For solving the problems of the technologies described above, a kind of pressing structure for keyboard of the utility model, comprise two pieces of runing rests arranged in a crossed manner, described runing rest comprises linkage section and is separately positioned on stiff end and the link at described linkage section two ends; Wherein said stiff end is connected with stainless steel base plate; Keycap is connected on described link; Salient point is provided with towards the side of described keyboard pcb at described linkage section; The described linkage section of two pieces of described runing rests intersects mutually, and two salient point laminatings on two pieces of described linkage sections form circular contact, for pressing the resilient contact switch on described keyboard pcb.
Preferably, described stiff end and described link are strip.
Preferably, angle is had between described stiff end length direction place straight line and described link length direction place straight line.
Preferably, described angle is 8 degree.
Preferably, described stiff end is provided with elongate holes.
Preferably, airfoil is provided with in the both sides of described link.
Preferably, the diameter of described contact is 1.0 millimeters, is highly 0.3 millimeter.
Preferably, the thickness of described runing rest is 0.2 millimeter ~ 0.5 millimeter.
Preferably, the material of described runing rest is stainless steel.
The lever that the stainless steel runing rest formation two ends intersecting placement after a kind of pressing structure for keyboard of the utility model utilizes two bendings balance, utilize the resilient contact switch on the boss point promotion circuit board in the middle part of stainless steel runing rest back segment, make circuit by tactile conducting, the thickness of pressing structure is little, when the resilient contact switch of use 0.2 millimeter ~ 0.4 millimeter of stroke, the stroke of pressing structure can reduce to 0.5 millimeter ~ 0.9 millimeter, thus greatly reduces the thickness of keyboard.
Accompanying drawing explanation
Fig. 1 is a kind of pressing structure rotary bracket structure schematic diagram for keyboard of the utility model;
Fig. 2 is the structural representation of a kind of pressing structure for keyboard of the utility model;
Fig. 3 is the non-pressed state figure of a kind of pressing structure for keyboard of the utility model;
Fig. 4 is a kind of pressing structure pressed state figure for keyboard of the utility model.
Embodiment
Below in conjunction with accompanying drawing, a kind of pressing structure for keyboard of the utility model is described in further detail.
As shown in Figure 1 to 4, a kind of pressing structure for keyboard of the utility model comprises stainless steel runing rest 1, two the stainless steel runing rests 1 after two bendings in combined crosswise, and the stainless steel runing rest 1 after bending forms lever, decreases the thickness of keyboard.The stiff end 3 of stainless steel runing rest 1 is connected on circuit board 5, at the link 4 of stainless steel runing rest 1, utilize the salient point 7 top circular contact 8 that lever principle makes on stainless steel runing rest 11 linkage section 2, obtain larger downward active force, thus promoting the resilient contact switch 9 of below, it makes wiring board contact conducting.After unclamping stainless steel runing rest 1, stainless steel runing rest 1 elasticity is recovered, and circular contact 8 departs from resilient contact switch 9, and resilient contact switch 9 recovers, and circuit disconnects, and completes and once presses circulation.There is a strip through hole 9 joint of stainless steel runing rest 1 leading portion and link 4 near the Position Design of leading portion, can improve feel during pressing.
Further, stiff end 3 is fixed on stainless steel base plate 5.Link 4 withstands keycap 6, angle between stiff end 3 and link 4 is 8 degree, the width of stiff end 3 and link 4 is greater than the width of linkage section 2, increase the stressed area of stiff end 3 and link 4, simultaneously link 4 both sides are respectively designed with an airfoil 1, for the coordinating of keycap 6, in addition, there is a strip through hole 10 stiff end 3 and link 4 joint near the Position Design of stiff end 3, can improve feel during pressing.
The lever that the stainless steel runing rest formation two ends intersecting placement after a kind of pressing structure for keyboard of the utility model utilizes two bendings balance, utilize the resilient contact switch on the boss point promotion circuit board in the middle part of stainless steel runing rest back segment, make circuit by tactile conducting, the thickness of pressing structure is little, when the resilient contact switch of use 0.2 millimeter ~ 0.4 millimeter of stroke, the stroke of pressing structure can reduce to 0.5 millimeter ~ 0.9 millimeter, thus greatly reduces the thickness of keyboard.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is not limited to embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modification or replacement are all included in the scope of the application.
