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.

Embodiment 1

[0055] (Embodiment 1): the present embodiment is a kind of double-precision electronic balance, see Figure 1 to Figure 10 As shown, it includes a loading board 1, a display screen 11, an adjustment switch 12, four first precision weighing assemblies 2 for supporting the loading board, and four first precision weighing assemblies for supporting the loading board and the first precision weighing assembly. The second precision weighing assembly 3, and four force guides 4 for transmitting the pressure on itself to the second precision weighing assembly.

[0056] In the present embodiment, the specific structure of the second precision weighing assembly 3 is as follows: it includes a deck 34 having an accommodation slot 33 and a slot, a second precision load cell 31 arranged in the slot, and abutting on the second The supporting foot 32 on the precision load cell 31, the spring cover 35 that covers the opening at the bottom of the accommodating groove 33 and has a center positioni...

Embodiment 2

[0066] (Embodiment 2): This embodiment is basically the same as Embodiment 1, the difference is: see Figure 11 to Figure 13 As shown, the force guide 4 in this embodiment and the deck 34 in the second precision weighing assembly are integrally made by injection molding. Compared with Embodiment 1, the force guide in this embodiment is no longer separate The bottom wall 41 is provided, but the top wall of the card seat 34 is directly used as the bottom wall 41 of the force guiding member in the first embodiment.

[0067] In addition, the specific structure of the first precision weighing assembly in this embodiment is as follows: it includes a mounting base 27 provided with a slot and an accommodating cavity, and a base that covers the bottom opening of the accommodating cavity in the mounting base and has a central through hole. The elastic cover 28 , the first precision load cell 22 located in the accommodating cavity and snapped into the slot, and the elastic supporting mem...

Embodiment 3

[0071] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 14 to Figure 18 As shown, the top end of the tubular support wall in the force guide is also provided with a square load-bearing plate 5 with four circular support holes 51, which is used as the force guide support part of the force guide in this embodiment. 40. The bottom wall of the carrier board still serves as the force-guiding crimping part 10.

[0072] In this embodiment, in the free state, the upper support member 212 of each elastic support member passes through a corresponding support hole 51 and is bonded and fixed on the bottom wall of the loading board, so that the force guiding crimping portion 10 of the loading board is higher than The force-guiding support part 40 of the force-guiding member; when the weight of the object on the loading plate exceeds a certain level, the loading plate moves down and is crimped on the load-bearing plate, that is, the force-guiding crimpin...

Abstract

An electronic scale includes a loading plate (1), a first precision weighing assembly (2) for supporting the loading plate (1), a second precision weighing assembly (3) for supporting the loading plate (1) and the first precision weighing assembly (2), and a force-guiding member (4) for transmitting itself pressure to the second precision weighing assembly (2). The first precision weighing assembly (2) includes an elastic support member (21). A force-guiding support part (40) is arranged on the force-guiding member (4). A force-guiding pressure welding part (10) is arranged on the loading plate (1). When there is no object on the loading plate (1), the force-guiding pressure welding part of the loading plate (1) is higher than the force-guiding support part (40) of the force-guiding member (4). When there are some objects on the loading plate (1), the loading plate (1) is stressed to press the elastic support member (21) to move down. After the loading plate (1) is stressed to a certain degree, the force-guiding pressure welding part (10) presses the force-guiding support part (40) of the force-guiding member (4). When the weight of the loaded objects exceeds the metre full scale of a kitchen electronic scale, the inventive electronic scale effectively prevents damage to the kitchen electronic scale besides the electronic scale is used as a weight electronic scale and the kitchen electronic scale at the same time.

Description

technical field [0001] The invention belongs to the technical field of electronic balance structure design, and in particular relates to an electronic balance. 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, but its measuring range is...
