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 button, 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 range of this kind of weight electronic scale is generally 180 kg, and the accuracy value is only 100 grams. The error is large. Therefore, this traditional weight electronic scale can basically not be used for other purposes except for weighing, especially it cannot be used as a kitchen electronic scale.
However, the existing kitchen electronic scales have an accuracy of 1 gram or even less, but their range generally does not exceed 10 kilograms, so they cannot be used as weighing scales.

Embodiment 1

[0026] This embodiment is an intelligent two-stage weighing electronic scale, see Figure 1 to Figure 11 As shown, it includes a carrier plate 91 for placing objects to be weighed; it is characterized in that: it also includes a base 92 arranged under the carrier plate and four double-stage scales for supporting the carrier plate arranged in the base Heavy sensor 93.

[0027] Each double-stage load cell includes a first mount 1, a first precision load cell 2, a first support foot 3, an elastic support 4, a second mount 5, and a second precision load cell 6, which are sequentially crimped. And the second supporting foot 7.

[0028] On the bottom wall of the first mounting seat, there is provided with an annular force-guiding crimping portion 11 and a first card seat 12 located at the center of the force-guiding crimping portion; in this embodiment, the bottom of the force-guiding crimping portion 11 The wall is an annular plane, and the top wall of the first installation seat...

Embodiment 2

[0055] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 12 to Figure 13 As shown, since the adjusting screw 83 is surrounded by the first mounting seat and the force-guiding support part, it cannot be rotated again after the overall assembly, so the adjusting mechanism 8 in this embodiment also includes an adjusting screw cover 81 and a top screw cover 82; the outer peripheral wall of the first installation seat is provided with an outwardly convex stopper 13, and the outer peripheral wall of the force guiding support part is provided with an external thread area 521; the inner wall of the upper part of the adjusting screw cap is provided with an inwardly convex annular anti The crimping part 811 is released, and the inner wall of the lower part is provided with an internal thread area 812 adapted to the external thread area of ​​the force guiding support part; the anti-off crimping part is sleeved on the outer periphery of the first mountin...

Embodiment 3

[0058] This embodiment is basically the same as Embodiment 2, the difference is: see Figure 14 to Figure 17 As shown, in this embodiment, the structural shape of the second precision load cell, the second support leg and the cover is different from that of Embodiment 2, and the second precision load cell in this embodiment is still provided with a second fixed part 61, the second force-bearing deformation part 62, and the second resistance strain gauge 63 arranged on the second force-bearing deformation part for detecting the deformation amount of the second force-bearing deformation part; but the second precision in this embodiment The shape of the load cell is similar to the reverse "G" shape, its second fixed part is similar to "C" shape, and the shape of the second force-bearing deformation part is similar to a smaller "C" shape, and it is connected with the second fixed part , combined to form a reverse "G" shape. The measuring range and precision of this second precisi...

Abstract

The invention discloses an intelligent two-step weighing electronic scale. The intelligent two-step weighing electronic scale comprises a loading plate on which an object to be weighed is placed, a base which is arranged below the loading plate, and two-step weighing sensors which are arranged in the base to support the loading plate. Each two-step weighing sensor comprises a first mounting seat, a first precision weighing sensor, a first support foot, an elastic support piece, a second mounting seat, a second precision weighing sensor and a second support foot, wherein the first mounting seat, the first precision weighing sensor, the first support foot, the elastic support piece, the second mounting seat, the second precision weighing sensor and the second support foot are successively crimped. Each first mounting seat is provided with a force transmitting crimp part. Each second mounting seat is provided with a mounting plate part and a force transmitting support part which is used for transmitting the received pressure to the mounting plate part. In a free state, each force transmitting crimp part is higher than each force transmitting support part. When a first mounting seat is stressed, an elastic support piece is compressed and moves down. When the first mounting seat is stressed to a preset extent, the force transmitting crimp part of the first mounting seat moves down to crimp a force transmitting support part. The intelligent two-step weighing electronic scale provided by the invention has two-step continuous range, and has different precision values in the range of each step.

Description

technical field [0001] The invention belongs to the technical field of weighing instruments, and in particular relates to an intelligent double-stage weighing 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 button, 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 range of this kind of weight electronic scale is generally 180 kg, and the accuracy value is only 100 grams. The error is large. Therefore, this traditional weight electronic scale can not be used for other purposes except weighing the body on weekdays, especially it cannot be used as a kitchen electronic scale. And existing kitchen electronic scale, its precision value can reach 1 gram even smaller, but...
