Double-purpose double-stage electronic scale

Abstract

The invention discloses a double-purpose double-stage electronic scale, and the electronic scale comprises a carrier plate and weighing sensor modules for weighing an object carried by the carrier plate. Each weighing sensor module comprises a force measurement sensor, a first supporting leg with a first supporting part, and a second supporting leg with a second supporting part. Each force measurement sensor comprises a fixed part, a first-precision elastic force-bearing part, and a second-precision elastic force-bearing part. The carrier plate is disposed on the fixed parts of the force measurement sensors in a crimping manner. The first-precision elastic force-bearing parts are disposed on the first supporting legs in a crimping manner, and the second-precision elastic force-bearing parts are disposed on the second supporting legs in a crimping manner. The second supporting legs are elastic supporting legs. At a free state, the second supporting parts independently support the whole electronic scale. When the carrier plate carries an 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.

Description

technical field [0001] The invention belongs to the technical field of structural design of electronic scales, and in particular relates to a dual-purpose double-stage electronic scale. Background technique [0002] The weight electronic scales currently on the market are mainly composed of a loading board, a display screen, an adjustment switch, a power module and a load cell for supporting the loading board. When the weight of the loaded object exceeds the preset value, the display screen will start to display the value. The preset value is generally 5 kg; in addition, the maximum measuring range of this kind of weight electronic scale is generally 180 kg, and the division value is 100 g, so the error is large , so this traditional body weight electronic scale can not be used as other things except for weighing body weight on weekdays, especially it cannot be used as a kitchen electronic scale. And existing kitchen electronic scale, its graduation value can reach 1 gram, ...

Problems solved by technology

[0002] The weight electronic scales currently on the market are mainly composed of a loading board, a display screen, an adjustment switch, a power module, and a load cell for supporting the loading board. When the weight of the loaded object exceeds the preset value, the display screen will start to display the value. The preset value is generally 5 kg; in addition, the maximum measuring range of this kind of weight electronic scale is generally 180 kg, and the division value is 100 g, so the error is large , so this kind of traditional weight electronic scale can't be used for other purposes except weighing weight, especially it can't be used as a kitchen electronic scale.

And the existing kitchen electronic scale, its indexing value can reach 1 gram, but its measuring range generally does not exceed 50 kilograms, so can not be used as weighing scale

At present, there are also electronic scales with a division value of 2 grams and a range of 150 kg on the market. They are made of force sensors with high precision and a large range, but they are very expensive and cannot be popularized.
