Embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model embodiment solution is mainly: adopt position limiting structure is set on button; External Force Acting is at button; elastic arm produces deformation; button moves downward and contacts with touch-switch, when external force increases, in elastic arm deformation allowed band; position limiting structure withstands on button and encloses bone edge; the button stop motion is transferred on position limiting structure from elastic arm the too much external force that button applies, and elastic arm and touch-switch are protected.
Please extremely shown in Figure 5 with reference to Fig. 3 in the lump, the utility model one embodiment proposes a kind of press-key structure, comprise that button 1, button enclose bone 3, elastic arm 2 and touch-switch (not shown) for elastic force is provided by key motion, elastic arm 2 two ends enclose bone 3 with button respectively and button 1 is connected, and button 1 is connected with touch-switch; Wherein, button 1 connect the first position limiting structures 5 away from elastic arm 2 one ends, the first position limiting structure 5 is positioned at button and encloses bone 3 tops, edge and certain vertical range is arranged each other, and this vertical range should drive in the scope that does not make elastic arm 2 that elastic deformations occur when elastic arm 2 moves or fracture with the first position limiting structure 5 and be as the criterion.button 1 is exerted pressure, button 1 moves together with the first position limiting structure 5, wherein, button 1 is oppressed touch-switch and is realized the opening operation of touch-switch, when continuing to apply external force and when elastic arm 2 allows in deformation ranges, last and the button of the first position limiting structure 5 encloses bone 3 EDGE CONTACT and withstands on this button and encloses on bone 3 edges, button 1 stop motion, touch-switch avoids being subject to the further extruding of button 1, well protected, after the pressure elimination that acts on button 1, elastic arm 2 drives button 1 and is connected with the touch-switch disengaging, button 1 is kept in the center, the first position limiting structure 5 encloses bone 3 edges disengagings with button.
In further implementation process, in order to guarantee that elastic arm 2 does not cause the deformation of self or fractures because being subject to excessive external force, employing arranges the second position limiting structure 6 at button 1 near elastic arm one end, and this position limiting structure 6 is positioned at button and encloses bone 3 tops, edge and certain vertical range is arranged each other.Button 1 is exerted pressure, button 1 moves to a certain degree, this position limiting structure 6 encloses bone 3 EDGE CONTACT with button and withstands on this button and encloses on bone 3 edges, this position limiting structure 6 has substituted elastic arm 2 and has accepted external force, avoided the strain that external force causes the excessive compressing of elastic arm 2 or fractureed, after acting on pressure on button 1 and eliminating, elastic arm 2 drives buttons 1 and is connected with the touch-switch disengaging, button 1 is kept in the center, and position limiting structure 6 encloses bone 3 edges disengagings with button.
The first position limiting structure 5 and the second position limiting structure 6 are the bulge-structure that is arranged on button 1 edge, and the first position limiting structure 5 and the second position limiting structure 6, elastic arm 2 and button 1 can be integrated.
In above embodiment, easily produce the problem of breakking away when contacting with touch-switch for fear of button 1, adopt on button encloses bone 3 edges and be provided with groove structure 8, and groove structure 8 be positioned at position limiting structure 5 under.Wherein, the first position limiting structure 5 encloses bone 3 border movements and enters at last this groove structure 8 perpendicular to button, the first position limiting structure 5 and the first groove structure 8 can be well chimeric, avoid the first position limiting structure 5 to move left and right when enclosing bone 3 border movement perpendicular to button, easily produce the problem of breakking away when therefore, also having avoided button 1 to contact with touch-switch.In like manner, on enclosing bone 3 edges, button is provided with groove structure 7, and groove structure 7 be positioned at the second position limiting structure 6 under, interactively and the relation between the first position limiting structure 5 and groove structure 8 between the second position limiting structure 6 and groove structure 7 and act on identically do not repeat them here.
In further implementation process, easily produce the problem of breakking away when further avoiding button to contact with touch-switch, the first position limiting structure 5 and the second position limiting structure 6 are arranged at respectively in groove structure 8 and groove structure 7, in the situation that button 1 is not subjected to External Force Acting, the first position limiting structure 5 or the second position limiting structure 6 have certain distance with groove structure 8 or 7 bottoms.
Compare in existing press-key structure, touch-switch is easily damaged by pressure by button and elastic deformation easily occurs elastic arm or the problem such as fracture, the utility model adopts position limiting structure is set on button, after button is stressed, this position limiting structure moves with button and finally withstands on button and encloses bone edge, born and be applied to pressure excessive on button, and stoped button further to move, this makes and the utlity model has following advantage:
(1) touch-switch can not be subjected to button with all one's strength to push up pressure and damage by pressure.
(2) elastic arm can not cause the elastic deformation of self or fracture because being applied to the excessive pressure on button.
(3) contact stabilization of touch-switch and button can not produce the problem of sideslip.
(4) press-key structure is more sturdy and durable, and is economical and practical.
The above is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
