[0002] With the application and development of microelectronics technology, people have designed various innovative electronic scales in order to change the problems existing in the use of traditional weighing tools. Electronic scales are not only a necessity in people's lives, but are also used in industrial production. Electronic scales, a type of weighing instrument, are tools that use Hooke's law or the principle of lever balance of force to measure the mass of an object. Electronic scales are mainly composed of three parts: a load-bearing system (such as a scale pan, a scale body), a force transmission conversion system (such as a lever force transmission system, a sensor), and a value indication system (such as a dial, an electronic display instrument). Due to the continuous changes in the application environment, the accuracy requirements of electronic scales are getting higher and higher, and traditional electronic scales are increasingly unable to meet people's needs.

[0003] Existing electronic scales generally measure the weight of the object being measured by directly placing the object on a tray for measurement. Sometimes, when the object is large in size, it will cause the scale to tilt when placed on the electronic scale, or the object will be tilted, which will cause errors in the data detected by the pressure sensor, reducing the measurement accuracy and failing to meet the needs of accurate weighing.

[0025] See also Figure 1-5 , the technical solution provided by this embodiment is as follows:

[0026] The high-precision electronic floor scale comprises: a shell 1, a base 3 is fixedly connected to the bottom of the shell 1, connecting columns 13 are fixedly connected to the four corners of the bottom of the base 3, a fixing mechanism 14 is fixedly connected to the bottom of the connecting column 13, a display screen 4 and a button 5 are arranged on the surface of the shell 1, a pressure sensor 8 is installed on the top of the shell 1, a lifting mechanism 9 is installed on the top of the pressure sensor 8, a weighing plate 10 is movably connected to the top of the lifting mechanism 9, a control device 11 is installed on the inner cavity surface of the shell 1, and a charging port 6 is arranged on the surface of the shell 1.

[0027] In a specific embodiment of the utility model, the connection between the device and the ground is strengthened by the setting of the fixing mechanism 14, so as to avoid the tilt of the scale body or the tilt of the object when the object tested by the existing device is large and placed on the electronic scale, thereby improving the precision of the high-precision electronic floor scale. The setting of the lifting mechanism 9 enables the user to adjust the height of the weighing plate 10 as needed, avoiding the problem of the user having to bend over for a long time when weighing, which may damage the body, thereby improving the health of the high-precision electronic floor scale.

[0028] Specifically, both side surfaces of the housing 1 are fixedly connected with carrying handles 2 , and the surfaces of the carrying handles 2 are provided with anti-slip covers.

[0029] In a specific embodiment of the present invention, the provision of the carrying handle 2 facilitates the user to move the device when in use, thereby improving the flexibility of the high-precision electronic floor scale.

[0030] Specifically, an external speaker 7 is installed on the surface of the shell 1 , and a voice announcer 12 is installed on the inner surface of the shell 1 . The external speaker 7 is electrically connected to the voice announcer 12 .

[0031] In a specific embodiment of the present utility model, the external speaker 7 and the voice announcer 12 are used in combination, so that the user can know the result through voice announcement when it is inconvenient for the user to change the numerical value, thereby improving the convenience of the high-precision electronic floor scale.

[0032] Specifically, the control device 11 includes an FPGA, a signal conversion circuit and a signal amplification circuit, and the signal amplification circuit is electrically connected to the pressure sensor 8, the FPGA and the signal conversion circuit.

[0033] In a specific embodiment of the utility model, the signal amplification circuit outputs the amplified signal to the signal conversion circuit, converts it into a digital signal that is easy to process and outputs it to the FPGA. After calculation, the data is then transmitted to the display screen 4 or broadcast by the external speaker 7, thereby improving the practicality of the high-precision electronic floor scale.

[0034] Specifically, the lifting mechanism 9 includes a sleeve column 901, a support column 902, a spring clamp column 903 and a through hole 904. The sleeve column 901 is installed on the surface of the pressure sensor 8, the support column 902 is slidably connected to the inside of the sleeve column 901, the through hole 904 is opened on the surface of the sleeve column 901, the spring clamp column 903 is fixedly connected to the surface of the support column 902, and the support column 902 is engaged with the spring clamp column 903.

[0035] In a specific embodiment of the present utility model, the spring clamping column 903 and the through hole 904 are used in combination, so that the user can press the spring clamping column 903 to adjust the support column 902 up and down inside the sleeve column 901 and release the spring clamping column 903 to fix it after adjustment. The height of the weighing plate 10 can be adjusted in this way, so that the user does not have to bend over and damage the body when measuring, thereby improving the practicality of the high-precision electronic floor scale.

[0036] Specifically, the fixing mechanism 14 includes a vacuum disk 1401, a connecting block 1402 and a control handle 1403. The vacuum disk 1401 is fixedly connected to the bottom of the connecting column 13, the connecting block 1402 is fixedly connected to the surface of the vacuum disk 1401, and the control handle 1403 is arranged on the surface of the connecting block 1402.

[0037] In a specific embodiment of the present invention, the coordinated use of the control handle 1403 and the vacuum plate 1401 allows the user to control the stable connection between the vacuum plate 1401 and the ground through the control handle 1403, thereby improving the stability of the high-precision electronic floor scale.

[0038] Specifically, the pressure sensor 8 is a resistive strain sensor, and there are two pressure sensors 8 symmetrically arranged on both sides of the housing 1 .

[0039] In a specific embodiment of the present invention, two pressure sensors 8 are provided to weigh the object, so that the weighing error is smaller and the measurement is more accurate, thereby improving the accuracy of the high-precision electronic floor scale.

[0040] Working principle: When in use, the user can use the carrying handle 2 to carry the device to the required position, and then break off the control handle 1403 to make the vacuum plate 1401 stably connected to the ground. At this time, the object to be weighed can be placed on the surface of the weighing plate 10. At this time, the pressure sensor 8 feels the pressure and deforms, causing the impedance to change. At the same time, the excitation voltage changes, and a changing analog signal is output. The signal is amplified by the signal amplification circuit and output to the signal conversion circuit, converted into a digital signal for easy processing and output to the FPGA. After calculation, the data is transmitted to the display screen 4 and broadcast by the external speaker 7, thereby realizing the weighing detection of the object. When the user needs to bend over for a long time when the plane is too low for weighing, the user can press the spring clamp column 903 so that the support column 902 can be adjusted up and down inside the sleeve column 901 and release the spring clamp column 903 for fixation after adjustment. In this way, the height of the lifting mechanism 9 is adjusted to change the height of the weighing plate 10 to increase the comfort of the user.
