Lower end closed is lived.Housing 1 of the present utility model, gripper shoe 6 can be formed by way of injection, it would however also be possible to employ metalwork is simultaneously
Formed by mach mode.
Described gripper shoe 6 is additionally provided with elastomer 7, the touch assembly in housing 1 inner chamber passes through 7, elastomer
Support is in described gripper shoe 6；Elastomer 7 can be bonded with touching assembly in the way of using glue material, to prevent from touching assembly
Come off.Elastomer 7 of the present utility model can adopt material well-known to those skilled in the art such as PC, TPU etc..Elastomer
7 have certain elastic performance, and when user presses and touches assembly, the elastomer 7 that touch assembly can extrude its lower end becomes
Shape, so that touch assembly the displacement towards gripper shoe 6 direction occurs；After external force cancels, make in the presence of elastomer 7
Assembly must be touched reset.
The quantity of elastomer 7 is preferably provided with two, is located at the two ends touching assembly respectively, by this two elastomers 7
Good support can be provided to touching assembly.Can also be that described elastomer 7 is in touch, with described, the ring that element shapes are mated
Shape structure, the elastomer 7 that the edge of touch assembly is annular with this is combined together, and extruding touches the diverse location of assembly, can make
There is crimp with the elastomer 7 of this touch assembly relevant position cooperation.Elastomer 7 of the present utility model can also buffer tactile
Touch the impulsive force that assembly brings to pressure transducer module, it is to avoid to pressure transducer mould when falling or under effect of rapid impact
The damage that group is brought.
Touch assembly of the present utility model includes the touch pad 2 stretching out from described housing 1 lumen openings end, with reference to Fig. 1.Institute
State touch pad 2 to stretch out so that user can be operated accordingly by touch pad 2 from the opening of housing 1, for example user can press
The upper end of pressure touch pad 2, lower end, or slide into the other end of touch pad 2 from one end of touch pad 2 etc..Wherein, described tactile
Touch assembly and preferably also include being arranged on the flanged structure 11 of touch pad 2 lower edge, on described flanged structure 11 and housing 1 inner chamber
The ledge structure of end setting is combined together, such that it is able to prevent touch assembly from deviating from from the inner chamber of housing 1.By this convex
The mode that edge, ledge structure are engaged belongs to the common knowledge of those skilled in the art, and here no longer illustrates.
Button module of the present utility model, is provided with least one pressure between described touch assembly and gripper shoe 6 and passes
Sensor module, described pressure transducer module is arranged to produce, according to the described pressing touching assembly, the pressure characterizing press degree
Force signal.
Pressure transducer module of the present utility model may be mounted in gripper shoe 6 it is also possible to be arranged on touch assembly,
When pressing touches assembly, touch the displacement being occurred after assembly extrudes elastomer 7 and can act on positioned at gripper shoe 6 and touch group
On pressure transducer module between part, thus the pressure touching assembly press degree is characterized by the output of pressure transducer module
Signal.This utility model one preferred embodiment in, described pressure transducer module includes circuit board 3 and and circuit
The pressure transducer of plate 3 electrical connection.Described circuit board 3 can adopt FPCB plate, and it can be arranged on the lower end touching assembly, example
As may be provided at the lower end of touch pad 2, pressure transducer and circuit board 3 link together so that the letter of pressure transducer output
Number can be transmitted to control end by circuit board 3.
Button module of the present utility model, by touching assembly, pressure transducer module is integrated in housing so that this pressure
Sensor can be directly installed on end product in the form of module, thus improving the efficiency of production.When user's pressing is touched
When touching assembly, touch assembly and can extrude distortional elastomer, so that defeated with the pressure transducer that touch assembly is combined together
Go out the signal of feedback, this feedback signal can be changed into the instruction of client terminal after back-end processing, it is achieved thereby that user couple
The control of exterior terminal.
In one specific embodiment of this utility model, described pressure transducer can be provided with two, remembers respectively
For first pressure sensor 4, second pressure sensor 5；Described first pressure sensor 4, second pressure sensor 5 are distributed respectively
At the two ends touching assembly.Here should be noted that " two ends " herein not only comprise to touch two tip position of assembly,
It should also be appreciated that being including touching two sides in length or width for the assembly, such as top, lower section, left, right, front
Side, rear etc..
With reference to the view direction of Fig. 1, such as, when on touch pad near the position stress of first pressure sensor 4, touch
Assembly integrally moves downward, and it is larger, away from first to touch the displacement occurring on assembly near first pressure sensor 4 one end
The displacement that pressure transducer 4 one end is occurred is less, and the whole assembly that touches occurs to be similar to the motion of " seesaw " formula, and this allows for
Touch assembly and its pressure to second pressure sensor 5 is more than to the pressure of first pressure sensor 4, so that first pressure passes
Sensor 4, second pressure sensor 5 can export different pressure signals, can obtain touching on assembly by subsequent calculations
Forced position point, it is achieved thereby that the judgement of human body gesture.Based on identical reason, when second pressure close on touch pad senses
During the position stress of device 5, this allows for touching the pressure to first pressure sensor 4 for the assembly less than it to second pressure sensor
5 pressure, can obtain touching forced position point on assembly it is achieved that the judgement of human body gesture by subsequent calculations.
It may further be preferable that being used in described gripper shoe 6 coordinating with first pressure sensor 4, second pressure sensor 5
Position be respectively arranged with the contact 10 of projection, described gripper shoe 6 pass through two contacts 10 respectively with first pressure sensor 4,
Second pressure sensor 5 is combined together, and such that it is able to greatly reduce the lifting surface area of two pressure transducers, thus can improve
The sensitivity of two pressure transducers.
Button module of the present utility model, is also provided with limited post 8 between described gripper shoe 6 and touch assembly.Should
Limited post can be fixed in gripper shoe 6 it is also possible to be arranged on touch assembly.Described limited post is preferably provided with two, point
It is not distributed in neighbouring first pressure sensor 4, the position of second pressure sensor 5, carried out by this two limited post 8 spacing,
Can prevent from excessively pressing and touch the damage that assembly is brought to first pressure sensor 4, second pressure sensor 5.
Button module of the present utility model, the position being connected with gripper shoe 6 in described housing 1 is additionally provided with around described shell
First sealing ring 9 of body 1 inner chamber.The sealing between housing 1 and gripper shoe 6 can be greatly improved by this first sealing ring 9
Energy.Certainly, it is used for the being also provided with around described housing 1 inner chamber is connected on the end face of exterior terminal in described housing 1
Two sealing rings 12, such that it is able to realize the sealing property of button module and exterior terminal, improve the waterproof and dustproof of button module
Ability.
