Brief description
This utility model will be expanded on further by accompanying drawing below, accompanying drawing is only example, only state a kind of optimization structure class
Type, wherein：
Fig. 1 shows the top view of the version according to operating unit 1 of the present utility model；
Fig. 2 shows the sectional view of the version shown in Fig. 1 according to operating unit 1 of the present utility model；
Fig. 3 shows the top view of operating unit shown in Fig. 1 and 2 when removing operating parts；
Fig. 4 shows the detailed view of bracket side turning arm 6 bearing arrangement at the axle journal 7 of base side.
Specific embodiment
Fig. 1 shows a kind of version of operating unit 1 described in the utility model.Permissible in top view shown in Fig. 1
See operating parts 4 and the affiliated operating surface 2 designing for touch input.Operating surface 2 is surrounded by a panel frame 3.Operating parts 4 and
Operating surface 2 can move with respect to panel 3 in diagram plane.Can represent that operator may see not by scope 2l, 2m, 2r
The region arrived, can carry out detecting for the touch differentiating position by the measurement of power according to these regions on operating surface 2.
Here position resolution operation will be carried out in three regions upwards in pure water square, can be considered according to resolution capability
Region on operating surface 2 for all directional spreding.The outside mineral glass layer that operating surface 2 passes through operating parts 4 determines, by this
Mineral glass layer operation part 4 has relatively large bending resistance stiffness.Figure it is seen that can be in area by operating unit 1
On domain 2l, 2m and 2r, resolved detection acts on operating physical force F operating surface 2, passing through the generation of one or more fingers of operator,
According to region or to touch the different electronic output signals of scope generation, finally can be operated accordingly by operating unit 1
Function.
Also touch feedback can be provided to operator simultaneously.This feedback produces in the force value such as more than regulation.
One actuator 13 is designed with according to this utility model, it makes operating parts 4 with respect to its pedestal 8, along perpendicular to operating physical force F simultaneously
The direction H being located in diagram plane enters vibration or impulse movement state.Operating parts 4 passes through leaf spring 12 support and is arranged on support
On 5, rotary motion can be executed.In another version, devise a suspended bearer above leaf spring.Leaf spring 12 edge
Elastic deformation in direction of motion H, thus producing return effect.It is rotatably mounted to pedestal in order to measure active force
On support 5, for touch design operating parts 4 the direction of motion on be fixed with respect to pedestal 8 by axle journal 7, so
It is not transmitted on support 5 by the motion that actuator 13 produces.So, it is maintained by propping up that turning arm 6 guides
The rotary motion of frame 5.In order to execute rotary motion, support 5 has the parallel rotating arm 6 of two holding one determining deviations, rotation
Pivoted arm is rotatably arranged on the axle journal 7 defining common axis of rotation in base side.Wherein pass through bearing arrangement part
Elastic pretension achieves gapless state, and this point will be illustrated below in reference to Fig. 4.Operating physical force F passes through operating parts 4 and borrows
The larger leaf spring of rigidity in the direction of extension 12 is helped to act on support 5, support passes through tappet shape projection 11 because of its rotatability again,
Act on the force transducer 10 between support 5 and pedestal 8.Force transducer 10 is located on a circuit board 9, and circuit board is fixed on pedestal
On 8.In order to realize between support 5 and force transducer 10 power gapless transmit, support by many compression springs 14 along
Force transducer 10 direction is by pretension (biasing).
Related with touching scope to touch shown in Fig. 1 that scope or Petting Area 2l, 2m, 2r be adapted in order to realize
Detection, support 5, between application point 12l and 12r applying operating physical force by operating parts 4 by leaf spring 12 and defining, compares
It is easier to bend.This requirement can be realized by following measures：Support 5 pass through two tabulars, respectively there is a turning arm 6
Section 5a, 5b and relatively thin, jointing 5a and 5b a connection sheet 15 are constituted, when operating surface 2 is subject to unilateral load
When (such as when the touch load that operating surface is subject to is not in centre), connection sheet can produce torsion and bend, so single when applying
Side load, when such as carrying out single operation in 2l or 2m of region, between support section 5a and 5b, relative motion will be produced.Cause
Respectively act on force transducer 11 belonging to for section 5a and 5b, different by producing on two force transducers 11 in this case
Electrical output signal is such that it is able to differentiate the touch location on operating surface 2 with reference to three scopes 2l, 2m, 2r.Support section 5a and 5b
Between the cavity that produced by connection sheet 15, be that the arrangement of actuator 13 provides space.
Show that the corresponding construction according to this utility model design, support 5 or its turning arm 6 pass through these by Fig. 4
Structure is arranged on the axle journal 7 of base side.Turning arm 6 has hole 18, and securing one by connection sheet in hole can be in radial direction
The upper ring 17 producing elastic deformation.The hole of ring 17 is used for the axle journal 7 of installation pedestal side.The hole of ring 17 is with respect to the diameter of axle journal 7
Undersize, because a rib 16 inwall protrusion from hole in radial directions, thus the turning arm 6 reducing support 5 exists
Clamping supported clearance on axle journal 7.
