Detailed description of the invention
(embodiment 1)
The present embodiment is a kind of double essence electronic scale, as shown in Fig. 1 to Fig. 7, including support board 1, display screen 11, regulation switch
12 and four for weighing the LOAD CELLS assemblies 2 of support board carrier weight；The shape side of being of support board in the present embodiment
Shape, uses glass or fiberglass to make；Four LOAD CELLS assemblies are evenly distributed at support board diapire corner.
In the present embodiment, each LOAD CELLS assembly includes plastic base the 3, first precision force cell the 8, second precision
Force cell 9, it is provided with first spike 5 of the first support 50 and is provided with second spike 6 of the second supporting part 60.
As shown in Fig. 5 to Fig. 7, in the present embodiment, the first precision force cell 8 includes first fixed part the 81, first bullet
Property load portion 82 and be arranged on the resistance strain gage (being not drawn on figure) in the first elastic load portion；In the present embodiment, first
After fixed part 81 is fixing, the first elastic load portion 82 becomes unsettled setting, thus elastic deformation occurs after stress, and then by electricity
Resistance foil gauge is converted into the signal of telecommunication the deformation of self.In the present embodiment the range of the first precision force cell 8 be 0 kilogram extremely
180 kilograms, precision (also referred to as scale division value) is 100 grams, is mainly used in weighing persons body weight.
Second precision force cell 9 includes the second elastic load portion 92 of fixed part 91, second and is arranged on the second bullet
Resistance strain gage (being not drawn on figure) in property load portion；The shape approximation of the second precision force cell 9 in the present embodiment
" G font ", the shape of the first precision force cell 8 then with the second precision force cell 9 symmetry " anti-G font ", when
So, other shape made by the first precision force cell 8 and the second precision force cell 9 is also feasible.Second is solid
Determine portion 91 fixing after, the second elastic load portion 92 becomes unsettled setting, thus elastic deformation occurs after stress, and then passes through resistance
Foil gauge is converted into the signal of telecommunication the deformation of self.In the present embodiment, the range of the second precision force cell 9 is 0 to 20 thousand
Gram, precision is 1 gram, is mainly used in kitchen articles and weighs.
Plastic base 3 includes roof 31 and containing cavity 32；The inwall of roof 31 is provided with for fixing the first fixed part 81
With the draw-in groove of the second fixed part 91, 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；First essence
The first precision elasticity load portion 82 crimping in degree force cell arranges on the top of support column 51, under free state, supports
The diapire of post 51 is unsettled.In concrete practice, first spike may be used without flexibly supporting foot, it is contemplated that the first precision bullet
Property load portion range more than the range in the second precision elasticity load portion, so first spike is when using resilient support foot,
Its coefficient of elasticity is greater than the coefficient of elasticity of the second resilient support foot.
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, the shape of lower support element 63
Shape is straight tabular, and the basal surface of lower support element is as the second supporting part 60；The second precision in second precision force cell
The crimping of elastic load portion 92 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
The first elastic plate 33 for spacing first spike 5 and the second elasticity for spacing second spike 6 it is provided with in 32
Plate 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 are equipped with inner ring, outer ring and connect inner ring and outer
Four spiral arm between circle, center positioning hole 331 and center spacing hole 341 be arranged on respective inner ring, and outer ring is fixing to be set
Put on containing cavity inwall；First elastic plate of this structure in use, can the most spacing first spike, and make
One spike transmits self pressure vertically downward；Second elastic plate of this structure in use, can be the most spacing
Upper supporting piece 62, and upper supporting piece is transmitted self pressure vertically downward.
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 screw thread
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, this mistake
In journey, the second supporting part individually supports whole electronic scale, and display screen can demonstrate the weight that the second precision elasticity load portion measures
Value, now the present embodiment can use as electronic scale.
After carrier heavily exceedes to a certain degree, such as time more than 20 kilograms, the bottom of support column 51 namely second supports
Portion 50 is displaced downwardly on the lower support element 63 that is crimped in second spike 6, and now the first supporting part and the second supporting part prop up jointly
Prop up whole electronic scale.Now all there is elastic deformation in the first precision elasticity load portion and the second precision elasticity load portion, and leads to
Cross resistance strain gage and respective deformation quantity is converted into the signal of telecommunication, by the intelligence computation of circuit, holding now can be calculated
Loading weight, now the present embodiment can use as body weight electronic scale again.
The first precision force cell 8 and the second precision force cell 9 in the present embodiment, can be criticized by impact style
Amount is made, 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 right
The restriction of embodiments of the present 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 these
Belong to obvious change that the connotation of the present invention extended out or variation still falls within protection scope of the present invention.
