Gravity sensor 6 senses that realization is weighed.
First way integrates gravity sensor, circuit board and battery due to needing on handle, can take larger sky
Between, and the handles of existing case and bag is often made very small at present, therefore handle do conference influence it is attractive in appearance；In addition, handle must be adopted
With hard plastics, not enough comfortably.
The second way is because current case handle 1 is generally designed using soft material, when carrying upwards, case and bag
Gravity is not the strength in a horizontal vertical direction, but is decomposed into F1 and closes the two power of F2, although F1 is equivalent to case and bag
Weight.But the strength that can produce so one horizontal direction of F2 is decomposed, and because the angle lifting angle [alpha] of handle is very big,
Therefore F2 strength can exceed well over F1.And gravity sensor 6 is only when all gravity is all perpendicular acting to gravity sensor 6
Upper just meeting is accurate.And aforesaid way can produce the F2 strength extruding gravity sensor 6 of horizontal direction, weighing precision is caused to reduce；
Additionally due to pull bar 5 can produce downward bending under gravity, when especially case and bag are heavier, level side in this case
To F2 strength a decomposing force vertically upward can be produced on gravity sensor 6 again, so can further reduce gravity sensitive
The precision of device 6.Pull bar 5 will have good toughness and toughness curve requirement to reach good uniformity, pull bar 5 be one piece very
Long steel disc and it can not be made too thick（Reduce volume）, so big steel disc will accomplish good toughness and to have accomplished consistent
Property, the cost of gravity sensor 6 can be greatly increased, gravity sensor 6 is generally using manganese steel as deformation steel, each portion at present
Position toughness uniformity be more difficult to accomplish, cause case and bag error in continuous weighting larger.
