The utility model discloses a high-speed force test probe can work under the low impact force state of high frequency, when the button is pushed down, measures the big or small change of button pushing down in-process dynamics. The probe of the utility model contains the S-shaped weighing sensor, has high precision, stable output and small volume, is suitable for being directly assembled on various sound rings and can also be assembled on a stepping motor for high-frequency test; the method is particularly used for keyboard mass production, and can obviously increase efficiency and ensure the accuracy of force signal output when a large number of tests are required.
Description
Technical field
The utility model relates to probe technologies field, especially relates to a kind of high speed Force meansurement probe.
Background technology
Along with developing rapidly of computer industry, now more and more higher to the processing and manufacturing quality of computer fittings, especially for computor-keyboard, the pressing quality of touch-screen.A lot of producer has not only only been concerned about the information interaction function of this kind of flexible member and basic computer, also requires that this series products allows user have better " pressing feel " to experience simultaneously.For this reason, stroke when being pressed by setting up flexible member and the curve of the stressed change of element surface assess its " feel " fine or not degree, and in other words this curve is exactly the assessment to keyboard quality.But existing assessment mode also exists, and efficiency is low, low precision, unstable shortcoming.
Summary of the invention
The utility model is intended to solve the problems of the technologies described above at least to a certain extent, the high speed Force meansurement probe providing a kind of result of use better.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
High speed Force meansurement is popped one's head in, and comprises stainless steel probe, S type LOAD CELLS, Wiring port, upper end cover, bottom end cover; Upper end cover, bottom end cover envelope stainless steel probe, S type LOAD CELLS; Wherein stainless steel probe extends outward outside upper end cover, and the position of stainless steel probe in upper end cover connects with S type LOAD CELLS.
S type LOAD CELLS sidewall is provided with Wiring port, and Wiring port is positioned at the joint of upper end cover, bottom end cover, and Wiring port main body is positioned at outside upper end cover, bottom end cover.
Multiple high precision electro resistive foil gauge is posted in S type LOAD CELLS.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
High speed Force meansurement probe of the present utility model can work under the low impulsive force state of high frequency, when button is depressed, measures the size variation of dynamics in button pressed process.The utility model probe includes S type LOAD CELLS, and precision is high, stable output, and volume is little, is applicable to directly being assemblied on various voice coil loudspeaker voice coil, also can be assemblied on stepper motor and carries out high-frequency test; When being used in particular for keyboard volume production, when needing to carry out a large amount of test, the utility model can increase efficiency significantly, also can ensure the accuracy that force signal exports simultaneously.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 is decomposition chart of the present utility model.
Embodiment
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent.
To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.
Below in conjunction with the Figure of description in the utility model, be clearly and completely described the technical scheme in utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1 ~ Figure 2 shows that can be used as the high speed Force meansurement probe of the utility model preferred embodiment, comprise stainless steel probe 1, S type LOAD CELLS 2, Wiring port 3, upper end cover 4, bottom end cover 5.
Upper end cover 4, bottom end cover 5 envelope stainless steel probe 1, S type LOAD CELLS 2; Wherein stainless steel probe 1 extends outward outside upper end cover 4, and the position of stainless steel probe 1 in upper end cover 4 connects with S type LOAD CELLS 2.
S type LOAD CELLS 2 sidewall is provided with Wiring port 3, and Wiring port 3 is positioned at the joint of upper end cover 4, bottom end cover 5, and Wiring port 3 main body is positioned at outside upper end cover 4, bottom end cover 5.In addition, multiple high precision electro resistive foil gauge 8 is posted in S type LOAD CELLS 2.
In practical application, stainless steel probe 1 for contact with elastic element: when stainless steel pop one's head in 1 top vertically applied pressure or pulling force by elastic element time, pressure is popped one's head in by stainless steel and 1 is passed in S type LOAD CELLS 2; After S type LOAD CELLS 2 one sections of pressurizeds, can there is deformation in its thinnest part, and small deformation can make stickup superincumbent high precision electro resistive foil gauge 8 that change in resistance occurs, thus outputed voltage signal in collecting device by Wiring port 3.
Wherein, upper end cover 4 with bottom end cover 5 for S type LOAD CELLS 2 provides protective effect; As shown in Figure 2, the bottom of bottom end cover 5 can be connected with bottom S type LOAD CELLS 2 by M3 screw 7, the bottom of bottom end cover 5 is furnished with the one-piece construction that 3 threaded holes are popped one's head in for fixing high speed Force meansurement, high speed Force meansurement probe can be linked other power part as voice coil motor.
Structure of the present utility model can have stable force signal to export within the scope of certain frequency, and inner sensor can be protected to be subject to mechanical damage simultaneously.In addition, because high speed Force meansurement probe size is less, the motor of different model or other high speed one-way movement devices is easily coordinated to use.
In sum, obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
