Keyboard is a kind of instruction and data input media 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 mellotron etc., keyboard contributes to practicing at typing.Keyboard is the most frequently used is also topmost input equipment, can be input in computing machine by English alphabet, numeral, punctuation mark etc. by keyboard, thus gives an order to computing machine, inputs data etc.

But in prior art, panel computer and notebook computer, for improving portability and dirigibility, extensively adopt independently keyboard as input media, and preferably to adopt wireless module to realize the push button signalling transmission of keyboard and panel computer and notebook computer.Because keyboard thickness is comparatively large, be difficult to the thickness of the expectation reducing to consumer, even if under the state reaching product thickness limit, the height stroke of button reduces greatly, affects feel, and the cost of manufacture of frivolous keyboard is higher in addition, and push button longevity is short, and thoughts and feelings rate is low.

Summary of the invention

The purpose of this utility model is to provide a kind of Wireless Keyboard solving Wireless Keyboard thickness in prior art and be difficult to thinning, that button height stroke is little, feel is poor technical matters.

For solving the problems of the technologies described above, the utility model Wireless Keyboard, comprises framework, button and keyboard pcb, it is characterized in that, is provided with the pressing structure for keyboard between described button and described keyboard pcb; The described pressing structure for keyboard is made up of two pieces of runing rests arranged in a crossed manner, and 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 keyboard pcb; 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.

Preferably, keyboard pcb is connected with wireless communication module.

The lever that the utility model Wireless Keyboard 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 reduce the thickness of keyboard, under the state reaching product thickness limit, keep applicable height stroke and feel, life-span is long, cost is few.

Embodiment

Below in conjunction with accompanying drawing, the utility model Wireless Keyboard is described in further detail.

As shown in Fig. 1 ~ Fig. 6, the utility model Wireless Keyboard, comprise stainless steel base plate 13, keyboard circuit 14 and button 12, wireless communication module and power supply is included in keyboard circuit 14, keyboard circuit 14 is arranged in stainless steel base plate 13, button 12 is arranged on stainless steel base plate 13, button utilizes button hook 5 to be connected with base plate, be distributed with a resilient contact switch 9 in stainless steel base plate 13 below any one button 12, resilient contact switch 9 is all connected with keyboard circuit 14 each via electric conductor.

Between button 12 and keyboard pcb, be provided with the pressing structure for keyboard, the pressing structure for keyboard is made up of in combined crosswise the stainless steel runing rest 1 after two bendings, 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 stainless steel base plate 13, 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 1 linkage section 2, obtain larger downward acting force, thus promote the resilient contact switch 9 of below, make it 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 13.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 11, 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 utility model Wireless Keyboard 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.

Preferably, keyboard pcb is connected with wireless communication module.

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.
