Abstract
The invention discloses a double-purpose electronic scale, and the electronic scale comprises a carrier plate and weighing sensor modules for weighing the weight of an object carried by the carrier plate. Each weighing sensor module comprises a plastic substrate, a force measurement sensor, a first supporting leg with a first supporting part, and a second supporting leg with a second supporting part. At a free state, the second supporting parts are lower than the first supporting parts, and the second supporting parts independently support the whole electronic scale. When the carrier plate carries the object, the carrier plate bears a force to drive the first supporting parts to move downwards. When the weight of the carried object exceeds a certain value, the first supporting parts move downwards to support the whole electronic scale along with the second supporting parts. The electronic scale can serve as a body weight electronic scale, and also can serve as a kitchen electronic scale.

The present embodiment is a kind of dual-purpose electronic scale, as shown in Fig. 1 to Fig. 7, including support board 1, display screen 11, regulation
Switch 12 and four LOAD CELLS assemblies 2 being used for weighing support board carrier weight；Support board in the present embodiment
Shape is square, uses glass or fiberglass to make；Four LOAD CELLS assemblies are evenly distributed on support board diapire corner
Place.
In the present embodiment, each LOAD CELLS assembly includes plastic base 3, force cell 4, is provided with the first support
First spike 5 of 50 and second spike 6 being provided with the second supporting part 60.
As shown in Fig. 5 to Fig. 7, the force cell in the present embodiment includes that 41, first precision elasticity of fixed part is held
The second precision elasticity load portion 43 of 42, one, power portion and be separately positioned on the first precision elasticity load portion 42 and second
The resistance strain gage (being not drawn on figure) in precision elasticity load portion 43；In the present embodiment, the basic configuration of fixed part is work
Font, encloses two breach of formation, and the first precision elasticity load portion and the second precision elasticity load portion are each located on one and lack
In Kou, the first precision elasticity load portion and the second precision elasticity load portion are each relatively fixed place, portion planar tilt and arrange,
Make fixed part after fixation, the first precision elasticity load portion and the second unsettled setting in precision elasticity load portion, thus be subject to
There is elastic deformation after power, and then by resistance strain gage, the deformation of self is converted into the signal of telecommunication.In the present embodiment
The range in one precision elasticity load portion 42 is 0 kilogram to 180 kilograms, and precision (also referred to as scale division value) is 100 grams,
It is mainly used in weighing persons body weight；The range in the second precision elasticity load portion 43 is 0 to 20 kilogram, and precision is 1 gram,
It is mainly used in kitchen articles to weigh.
Plastic base 3 includes roof 31 and containing cavity 32；The inwall of roof 31 is provided with for fixing force cell solid
Determining the draw-in groove in portion 41, the upper surface of roof 31 is bonded and fixed on support board 1 diapire.
First spike 5 includes columned support column 51, and the basal surface of support column is as the first supporting part 50；Dynamometry
The first precision elasticity load portion 42 crimping in sensor is arranged on the top of support column 51.In concrete practice, first
Prop up spike to may be used without flexibly supporting foot, it is contemplated that the range in the first precision elasticity load portion is more than the second precision elasticity load
The range in portion, so first spike is when using resilient support foot, its coefficient of elasticity is greater than the second resilient support foot
Coefficient of elasticity.
Second spike 6 is resilient support foot；Second spike 6 includes screw thread spring 61, is fixedly installed on screw thread spring
The upper supporting piece 62 on top, it is fixedly installed on the lower support element 63 of screw thread spring bottom end；In the present embodiment, lower support element
63 be shaped as straight tabular, the basal surface of lower support element is as the second supporting part 60；The second essence in force cell
Degree elastic load portion 43 crimping is arranged on upper supporting piece 62.
In the present embodiment, for the most spacing first spike 5 and second spike 6, also at plastic base containing cavity
Be provided with in 32 the first elastic plate 33 for spacing first spike 5 and for spacing second spike 6
Two elastic plates 34.
First elastic plate center is provided with center positioning hole 331, and the first elastic plate is set in by this center positioning hole 331
On the periphery wall of support column 51, the neighboring of the first elastic plate is fixedly installed on the inwall of plastic base.
Second elastic plate center is provided with center spacing hole 341, and the second elastic plate is set in by center spacing hole 341
On the periphery wall of support member 62, the neighboring of the second elastic plate is fixedly installed on the inwall of plastic base.
In order to not affect second spike 6, the first elastic plate being additionally provided with the first breach 332, second spike is positioned at this
In first breach 332.
In order to not affect first spike 5, the second elastic plate being additionally provided with the second breach 342, first spike is positioned at this
In second breach 343.
In the present embodiment, the first elastic plate 33 and the second elastic plate 34 be equipped with inner ring, outer ring and connect inner ring and
Four spiral arm between outer ring, center positioning hole 331 and center spacing hole 341 be arranged on respective inner ring, outer ring
It is fixedly installed on containing cavity inwall；First elastic plate of this structure in use, is possible to prevent first spike certainly
Body pressure experienced passes to plastic base 3 by the first elastic plate, it is to avoid weighing by mistake occurs in the first precision elasticity load portion
Difference；Second elastic plate of this structure in use, is possible to prevent second spike self pressure experienced by second
Elastic plate passes to pedestal 3, it is to avoid weighing error occurs in the second precision elasticity load portion.
Under free state, under the resilient support effect of second spike, the second supporting part 60 is less than the first supporting part 50,
The first unsettled setting of supporting part 50, now the second supporting part individually supports whole electronic scale.
During support board carrying object, support board stress and then drive the first supporting part move down；By selecting suitable thread bullet
Spring, when can make on support board carrier heavily less than 20 kilograms, the second supporting part 60 is consistently lower than the first supporting part 50,
During this, the second supporting part individually supports whole electronic scale, and now display screen can demonstrate the second precision elasticity load portion
The gravimetric value measured.
After carrier heavily exceedes to a certain degree, such as, time more than 20 kilograms, the bottom of support column 51 is displaced downwardly to be crimped on
On lower support element 63 in second spike 6, now the first supporting part and the second supporting part support whole electronics jointly
Scale.Now all there is elastic deformation in the first precision elasticity load portion and the second precision elasticity load portion, and passes through resistance-strain
Sheet is converted into the signal of telecommunication respective deformation quantity, by the intelligence computation of circuit, can calculate carrier weight now,
So now the present embodiment can use as scale again.
Force cell in the present embodiment, can be made by impact style batch, and its price is the cheapest, effectively reduces
The manufacturing cost of the present embodiment.
Obviously, the above embodiment of the present invention is only for clearly demonstrating example of the present invention, and is not to this
The restriction of the embodiment of invention.For those of ordinary skill in the field, the most also may be used
To make other changes in different forms.Here without also cannot all of embodiment be given exhaustive.And this
Belong to obvious change that the connotation of the present invention extended out a bit or variation still falls within protection scope of the present invention.
