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 combined load cell, see Figure 1 to Figure 6 As shown, it includes a mounting base 1, a first precision load cell 2, an elastic support 3, a second precision load cell 4 and a supporting foot 5; the elastic support includes an upper support 31, a spring 32 and a lower support 33, The top end of the spring abuts on the upper support, and the bottom end of the elastic support abuts on the lower support; the mounting seat, the first precision load cell, the upper support, the spring, the lower support, the second precision scale The heavy sensor and the supporting feet are sequentially crimped and arranged; the upper support member is provided with a force guiding crimping part 311, and the supporting leg is provided with a force guiding support part 51; in a free state, the force guiding crimping part is higher than the force guiding supporting part; the upper support When the part is under pressure, the spring is compressed, and then th...

Embodiment 2）

[0047] This embodiment is basically the same as the above-mentioned embodiment 1, the difference is: see Figure 7 to Figure 8 As shown, this embodiment also includes an adjustment mechanism 6 for adjusting the overall height of the elastic support; the outer peripheral wall of the supporting leg is provided with a convex stop portion 52, and the outer peripheral wall of the force-guiding crimping part is provided with an external thread Area 314; the adjustment mechanism includes an adjustment screw cap 61 and a top screw cap 62, the inner wall of the lower part of the adjustment screw cap is provided with an inwardly convex annular anti-off crimping part 611, and the inner wall of the upper part is provided with a guiding force crimping part The internal thread area 612 adapted to the external thread area; the anti-off crimping part is sleeved on the outer peripheral wall below the stopper part of the lower support, and the top screw cap is screwed on the external thread area...

Embodiment 3）

[0050] This embodiment is basically the same as the above-mentioned embodiment 2, the difference is: see Figure 9 to Figure 12As shown, the first precision load cell in this embodiment is still provided with a first fixing part, a first force-bearing deformation part, and a sensor set on the first force-bearing deformation part for detecting the deformation of the first force-bearing deformation part. The amount of the first resistance strain gauge; but the shape of the first precision load cell in this embodiment is similar to the reverse "G" shape, its first fixed part is similar to "C" shape, and the shape of the first force-bearing deformation part is similar to Based on a smaller "C" shape, it is connected with the first fixing part to form a reverse "G" shape. The range and accuracy of this first precision load cell are the same as those in Embodiment 2, and this structure can also be made by stamping, and its manufacturing process is simpler. The bottom of the mountin...

Abstract

The invention discloses an intelligent combined weighing sensor. The intelligent combined weighing sensor comprises a mounting base, a first precision weighing sensor, an elastic support part, a second precision weighing sensor and a support foot; the elastic support part comprises an upper support part body, a spring and a lower support part body, the top end of the spring is connected to the upper support part body in an abutted mode, and the bottom end of the spring is connected to the lower support part body in an abutted mode; the mounting base, the first precision weighing sensor, the upper support part body, the spring, the lower support part body, the second precision weighing sensor and the support foot are sequentially arranged in a crimped mode; the upper support part body is provided with a force guide crimping part, and the support foot is provided with a force guide supporting part; in a free state, the force guide crimping part is higher than the force guide supporting part; when the upper support part body bears pressure, the spring is compressed, and then the force guide crimping part is driven to move downwards; when the upper support part body bears the pressure at a preset degree, the force guide crimping part moves downwards to be crimped on the force guide supporting part. The intelligent combined weighing sensor has double-stage continuous ranges, and different precision values exist in ranges of both stages.

Description

technical field [0001] The invention belongs to the technical field of load cell structure design, and in particular relates to an intelligent combined load cell. 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 its measuring...
