Description
Technical field
The utility model is related to the technical field of measurement and test of keyboard, refer in particular to mechanically or manually survey single key
The feel measuring head module of examination.
Background technology
A large amount of due to computer popularize, and people mostly carry out human-computer dialogue by keyboard, to using the quality requirements of keyboard
Raising, whether the quality of the function feel of keyboard, be directly related to typing whether information accurate and the longevity of keyboard
Life.For this purpose, factory while producing product, is required for carrying out physical testing to the key of keyboard, existing detection technique is all
It is to realize that button rebound dynamics output, test system are acquired test by data collecting card by force sensor,
That is data collecting card acquires force sensor to keyboard bounce, computer software is tested system and is carried out to gathered data
Analysis and processing, the qualified or not conclusion of product is obtained according to data.But in detection process, since force sensor acquires
Dynamics range is not necessarily applicable in all dynamics acquisition schemes, and such as protection probe is compressed in 150 gram forces or so beginning at present, such as
Fruit tests bounce and is more than 150 gram forces at present, then the protection probe has begun to compress, then the dynamics of testing will appear inaccuracy
Phenomenon, because a part of bounce is absorbed by probe.
Invention content
The purpose of this utility model be to provide it is a kind of can more than setting pressure can carry out self-protection feel survey
Try head mould group.
In order to achieve the above objectives, the technical solution of the utility model is as follows：Feel measuring head module is passed by shell 1, dynamics
Sensor 2, probe 3, amplifying circuit 4, signal wire 5 and signal connector 6 form, and shell 1 is used for preserving internal circuit and amplification electricity
Road 4, for force sensor 2 by signal wire 5 by the electric signal transmission of pressure conversion to amplifying circuit 4, amplifying circuit 4 passes dynamics
The signal of sensor 2 is converted to the signal that instrument can acquire and is sent out by signal connector 6；It is installed on force sensor 2
Elastic component.
The elastic component is probe 3.
The utility model is used alone, and integrates amplifying circuit and is integrated with force sensor, compact facilitates same opportunity
The advantages that structure is installed, and data stability is good, fast response time；Using probe and force sensor connection mode, protect very well
Inductor head is during the test to the damage of measuring head.
Description of the drawings：
Attached drawing 1 is the utility model front view；
Attached drawing 2 is the A-A sectional views of attached drawing 1；
Attached drawing 3 is the utility model stereogram.
Specific implementation mode：
As shown in Figures 1 to 3, feel measuring head module, by shell 1, force sensor 2, probe 3, amplifying circuit 4, signal
Line 5 and signal connector 6 form, and shell 1 is used for preserving internal circuit and amplifying circuit 4, and force sensor 2 passes through signal wire 5
By the electric signal transmission of pressure conversion to amplifying circuit 4, the signal of force sensor 2 is converted to instrument by amplifying circuit 4 can be with
The signal of acquisition is sent out by signal connector 6；It is installed with elastic component on force sensor 2.
The elastic component is probe 3.
When using the utility model, motion drives the utility model slowly contact product, the rebound of test request product
Power need to be less than 120 gram forces.After touching product, force sensor 2 starts to generate voltage signal, will be electric by amplifying circuit 4
Pressure signal is converted to the signal that can be acquired（Test system can start gathered data）, when the utility model continues the dynamics pushed
After 150 gram forces, force sensor 2 starts to compress probe 3（It is not damaged by excessively big pressure for protection sensor 2
It is bad）So that inductor head is constantly in maximum dynamics output mode, but not because of excessive pressure damage.Motion returns
Hui Shi, protection probe 3 slowly rebounds, and after slowly leaving product, the output of inductor head dynamics is also slowly decreased to 0.
Claims (2)
