Description
Technical field
The present invention relates to a kind of elastic arm key structure, particularly a kind of elastic arm key structure that is applied to have the electronic installation of touch control unit.
Background technology
Present electronic installation is the notebook computer, mobile phone, personal digital assistant (the Personal Digital Assistant that use always of people for example; PDA) and the function of digital camera constantly strengthen, and the function of these electronic installations is chosen and must be finished by the button on the control panel that is arranged at electronic installation, so will cause number of keys to increase.For complying with the portable development trend of electronic installation, it is impossible to increase number of keys, has only the keypress function of employing many with satisfying the above-mentioned facts.So design four directionkeys ingenious, that area occupied is less and powerful promptly arise at the historic moment, and become standard configuration such as notebook computer, mobile phone, personal digital assistant and digital camera.
See also Fig. 1, be the press-key structure schematic diagram of prior art, as shown in the figure, this press-key structure 1 for the four directions that is applied to notebook computer to button, and in this notebook computer relatively this press-key structure 1 be provided with four touch control units (figure does not mark).This press-key structure 1 is made up of press section 10, four elastic joint parts 11 and two fixed parts 12; Wherein, this press section 10 pushes along this that direction moves and can touch aforementioned this touch control unit, this four elastic joint part 11 is symmetricly set in 10 both sides, press section, after discharging, the external force of these press section 10 pressurizeds provides elastic-restoring force, this fixed part 12 is connected to this elastic joint part 11, to be fixed on this notebook computer.
After this press-key structure 1 is arranged at this notebook computer by this fixed part 12, the user can be by pushing this press section 10 and making this elastic joint part 11 that strain take place, thereby make this press section 10 touch touch control unit (figure does not mark), with input control information, the elastic-restoring force that is provided by this elastic joint part 11 makes this press section 10 return back to original position in pushing after external force discharges then.
Yet, the elastic joint part 11 of this kind press-key structure 1 is not because of there being the structure of any reinforcement rigidity, cause respectively these elastic joint part 11 discontinuity equalizations, can produce big displacement in the non-direction of pushing when pushing this press section 10, button is produced rock, use and influence button, What is more, may rock because of button and cause the press section repeatedly to trigger touch control unit (figure do not mark) in 11 short time, cause non-essential misoperation.
See also Fig. 2, press-key structure schematic diagram for another prior art, as shown in the figure, this press-key structure design is designed to U type bending structure to elastic joint part 21, attempt strengthens the rigidity of elastic joint part 21, so, when the user pushes directionkeys about this, because of the deflection that this elastic joint part 21 is provided limited, and no any connection between each elastic joint part 21, push the local time of this press section 20 in the user,, cause this press-key structure 2 to produce and rock so still can produce distortion power because of these elastic joint part 21 discontinuity equalizations respectively.
Therefore, how a kind of press-key structure that overcomes above-mentioned prior art various shortcoming is provided, produces the problem that button rocks when pushing this press section, simultaneously with solution, make simple in structure and don't increase design cost, the technical problem that needs to be resolved hurrily at present for the dealer of association area in fact.
Summary of the invention
