Definitions

  • the present invention relates to an electronic device, in particular a mobile device, a keyboard for a electronic device and a method for positioning a Keyboard of an electronic device.
  • an electronic Device in particular a mobile device from several Units are assembled, requiring construction respectively assembling an electronic device, especially a mobile device a whole range of tolerances and a good relative alignment of the different units to each other to make it work properly of the device.
  • By granting of certain tolerances, for example, the possible Influence of manufacturing inaccuracies on the functionality of the electronic device can be prevented.
  • a keyboard generally has multiple keys, that have a certain functional structure. Outward each key has a key cap, by means of which the Button can be operated by a user. For realization a key function also requires interaction the button with a circuit board of the electronic device. This is generally done via a specific one on the circuit board arranged and activatable contact point. On a Printed circuit boards are generally a number of such Contact points arranged, the activation of certain Realize key functions.
  • To activate the contact points has a button on the circuit board side at least one so-called actuator on when the button is pressed a user the appropriate contact point on the circuit board activated.
  • a switching film provided that a number of switching elements, usually in the form of metal or polydomes, having.
  • the Actuators of the keyboard which are used to activate corresponding Contact points on a printed circuit board of the electronic Device are exactly centered above the switching elements of the switching unit, the switching unit in turn according to the position of the contact points on the circuit board is aligned with the circuit board and on the other hand the key caps on the keyboard to the corresponding Key breaches of the housing of the electronic device be aligned according to good optics.
  • Is for a key cap provided exactly one key break, so the keycap should be centered, for example are in the key break.
  • the remaining tolerance is compliance with both requirements not to. This means that in case of tolerance compensation in positioning the actuators with uncontrollable Losses in the tactility of the keys expected must become. If you compare the tolerance with the Key caps in the corresponding key openings in the housing of the mobile device, the optically not optimal Accepted the position of the keycaps in the key openings become. That means that in the event that for a Keycap exactly one key break is provided, this then lie, for example, off-center in the key opening would.
  • An object of the present invention was now to electronic device, in particular a mobile radio device, or to provide a method by means of which at the same time good tactility of the keyboard and good looks are guaranteed can be.
  • the key cap and the actuator are preferably such slidable against each other that the key cap on the at least one key break in the case shell they towered through, can be aligned and at the same time the minimum an actuator for activating a corresponding one on the Printed circuit board arranged to implement at least one Key function activatable contact point centrally above a corresponding switching element can be positioned.
  • the switching unit can be, for example, a film act with metal domes or polydomes as switching elements. The switching unit must be aligned on the circuit board in this way be the contact points of the circuit board can be activated by the switching elements. When pressed the key force is applied to the transfer at least one actuator to the corresponding key.
  • the corresponding switching element for example a metal dome or a polydome, deformed in such a way that it in active contact with a corresponding contact point the printed circuit board occurs, which is thereby activated, namely by specifically closing contacts on the circuit board.
  • a button can have several actuators.
  • a polydome can be made of polyester or nylon his.
  • the geometry of the domes is arbitrary.
  • Conceivable is a raised, for example pointed at the top point of a cathedral, which in addition to exact positioning the actuators have a central or central actuation is favored.
  • the electronic device is preferably the electronic device around a cellular device.
  • electronic device is the key cap of at least one Key and the at least one circuit board arranged Actuator of at least one button in between the key cap and the actuator arranged level against each other displaceable, preferably in a plane parallel to the circuit board of the electronic device according to the invention.
  • This plane which acts as the parting plane between the actuator and the keycap of the key serves, should be close above the Actuators are located in this area as free as possible Slidability is given without the housing shell could narrow it.
  • the keycaps and the actuators are finite Tolerance range can be shifted against each other. It depends on the size of the keycap.
  • a keyboard for a electronic device provided, the first and one has second unit, the first and second units are in active contact with each other and relative to each other are movable and the first unit at least one Key cap and the second unit at least one actuator to activate at least one on a circuit board arranged and activatable contact point.
  • Pressing a key cap causes that at least an actuator operates and with the appropriate arrangement relative to a circuit board of an electronic device a specific one arranged and activatable on this circuit board Contact point activated.
  • the at least one keycap is now relative to the at least one according to the invention Actuator can be moved within a certain finite tolerance range.
  • Keyboard are the key caps using a polycarbonate film or bonded together using silicone.
  • the keycaps can also be connected by means of narrow webs his.
  • the keycaps can have any shape or design to have. Among other things, ribs on the Bottom conceivable as well as closed areas.
  • the actuators are preferably in a silicone base contain.
  • Another object of the invention was to provide a method with the help of which it becomes possible to position a keyboard of an electronic device, in particular optimize with regard to their tactile behavior. According to the invention, this object is achieved by a method according to claim 8.
  • the first and second units are the keyboard in a plane parallel to each other relative to the circuit board displaceable.
  • FIG. 1 is a section through an embodiment of a shown electronic device 1 according to the invention.
  • a circuit board 2 of the electronic device 1 On a circuit board 2 of the electronic device 1 is one can be activated to implement at least one button function Contact point 3 arranged.
  • a switching unit 4 is provided, which on the printed circuit board 2 is aligned that a switching element 5 centrally above the contact point 3 is positioned.
  • the switching element 5 it can be, for example, a metal dome or a polyester dome.
  • a key 6 is provided to activate contact point 3 .
  • This key 6 exists of two units, namely an actuator 7, the Printed circuit board 2 is facing and when the contact point is activated 3 depresses the switching element 5 on the printed circuit board 2 and thus a contact of the contact point 3 on the Circuit board 2 closes and from a key cap 8 that protrudes through a key opening 9 of a housing shell 10.
  • the key cap 8 and the actuator 7 are in operative contact to each other, i.e. when operating or when pressing the key cap 8 this force is exerted on the keycap 8 automatically transferred to the actuator 7, which is then the contact point 3 depresses so that a contact on the circuit board 2 is closed.
  • a plane 11 that is parallel runs to the circuit board 2, the actuator 7 and the key cap 8 separated from each other, i.e.
  • the actuator 7 and the keycap 8 relative to each other in a finite Tolerance range 12 can be moved parallel to circuit board 2.
  • the key cap 8 accurate to be arranged centrally in the key opening 9 of the housing shell 10 and at the same time the actuator 7 is exactly centric to position above the switching element 5, so that a central or central actuation is guaranteed. Consequently the tactile behavior of the keyboard can be optimized and at the same time a good optical appearance of the electronic Device are granted.
