Description
Technical field
The invention belongs to electronic balance structure design field, be specifically related to a kind of electronic scale.
Background technology
Body weight electronic scale in the market, its structure mainly includes carrying disk, display screen, power module and weighing and sensing
Device forms, and its function is mainly used in human body of weighing, and substantially after exceeding preset value until title weight of object, display screen is just opened
Begin display numerical value, and this preset value is usually 5 kilograms；It is it addition, the range of this kind of body weight electronic scale is usually 180 kilograms, bigger,
In order to reduce cost, the LOAD CELLS that precision is relatively low the most all selected by this kind of electronic scale, such as by kilogram in units of come
Saying, its display numerical value is one decimal place, namely its levels of precision is hectogram.So this traditional body weight electronic scale is on ordinary days
In addition to weighing in, substantially cannot function as its use, especially cannot be used for using as electronic scale.If it addition, choosing
Realize weighing with the LOAD CELLS that precision is higher, can use as electronic scale again, be not ask technically
Topic, it is contemplated that precision to be at least up to by gram or 0.1g in units of, also want the range upper limit to reach 180 kilograms, this title
The cost of weight sensor will be higher, at least cannot compete with conditional electronic scale in price.
Summary of the invention
It is an object of the invention to provide a kind of both can be as wide range, body weight electronic scale that precision is low, again can conduct
The electronic scale of the electronic scale that small-range, precision are high.
The technical scheme realizing the object of the invention is: a kind of electronic scale, including the first support board, has the first of a spike
Weighing cell module, display screen, regulation switch and power module；First Weighing cell module is just being positioned at the first support board
Lower section, each spike is positioned at the lowermost end of the first Weighing cell module；Its construction features is: also include the second support board,
There is the second Weighing cell module of support column；Second support board is arranged on the first support board, the second LOAD CELLS
Module is arranged under the first support board, and the bottom of a spike is less than the second Weighing cell module；First support board is provided with
Hole, each support column is positioned at the underface of a corresponding open-work, and the bottom of the second support board is provided through open-work and is crimped on a spike
On support；Second Weighing cell module includes the plastic base being bonded and fixed on the first support board diapire, fixing sets
Put on plastic base and there is the sensor installation seat of mounting groove, the second force cell being arranged in mounting groove, capping
Live mounting groove opening and center has the elastomeric cap of annular spacing groove and is fixed on the force-transmitting block bottom elastomeric cap；Elastomeric cap
With the support column described in force-transmitting block combination formation；The upper end of force-transmitting block forms the diapire of annular spacing groove, the lower side pressure of force-transmitting block
It is connected on the second force cell；The shape in the second support board bottom supporting portion is annular tube shaped, and this support is through the first load
Insert in described annular spacing groove after open-work on thing plate, and be directly crimped on the top of force-transmitting block.
In such scheme, each supporting portion leaves gap between part wall body and the inwall of this endoporus in open-work.
In the present invention, the first Weighing cell module selects wide range but the relatively low LOAD CELLS of precision, and second weighs
Sensor assembly selects small-range but the higher LOAD CELLS of precision.In use, owing to a spike is positioned at lowermost end, so
Support heel brace and play all of weight, if now the second support board is taken down, or sufficiently large for the first support board so that
User may stand on the first support board, does not touch the second support board, namely the second Weighing cell module is inoperative,
Now can be selected by regulation switch, make on display screen, to be shown that the weight amount that the first Weighing cell module is measured,
Namely can be with weighing persons body weight；When each support of the second support board is crimped on corresponding support column through open-work,
Then object can be placed on the second support board, now can be selected by regulation switch, make to be shown that on display screen the
The weight amount that two Weighing cell modules are measured, so can use as electronic scale again.It addition, in the present invention
One Weighing cell module and the second Weighing cell module, can use LOAD CELLS the most ripe and cheap on market,
So its manufacturing cost is much lower compared with using wide range and the high single-sensor of precision, there is preferable competitiveness.
