Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] See Figure 1 As shown, this utility model embodiment provides an intelligent scale equipped with a color display screen, including a housing 1, a cover 2, a color display screen 3, and a main control unit 5.

[0023] In this embodiment, the cover 2 and the housing 1 cooperate to form a receiving cavity; the color display screen 3 is fixedly connected to the housing 1, and at least a portion of the color display screen 3 is located inside the receiving cavity.

[0024] More specifically, to better secure the color display screen 3 and prevent it from detaching, a display frame 6 is added between the color display screen 3 and the cover 2. Two first latching protrusions 61 are provided on both the left and right sides of the display frame 6, and corresponding second latching protrusions 16 are provided on the housing 1 to engage with the first latching protrusions 61. After the display frame 6, the color display screen 3, and the main control unit 5 are assembled into a single unit, this unit is attached to the housing 1 via a snap-fit ​​connection, i.e., the first latching protrusions 61 and the second latching protrusions 16 engage with each other. To further enhance the connection strength between the display frame 6, the main control unit 5, and the housing 1, in this embodiment, fixing holes are provided on both the display frame 6 and the main control unit 5. Correspondingly, fixing posts are provided on the housing 1, with threaded holes inside, so that the display frame 6, the main control unit 5, and the housing 1 can be connected by threads to further enhance the connection strength between the three components.

[0025] Among them, the color display screen 3 is a TFT color display screen or an OLED color display screen.

[0026] In this embodiment, the test terminal includes a weighing component 4 and a lipid measurement electrode (not shown in the figure). Both the weighing component 4 and the lipid measurement electrode are connected to the front-end test module circuit.

[0027] Each liquid crystal pixel on a TFT color display is driven by a thin-film transistor integrated behind the pixel, giving the TFT color display advantages such as high responsiveness, high brightness, and high contrast. Therefore, in this embodiment, a TFT color display is preferred. Of course, an OLED color display can also be used, and those skilled in the art can choose according to actual production needs.

[0028] See Figures 1-2 As shown, mounting holes 11 are provided at the four corners of the housing 1, and annular protrusions 12 are provided on the bottom surface of the housing 1. One end of the mounting hole 11 passes through the housing 1, and the other end of the mounting hole 11 passes through the annular protrusion 12. A mounting plate 15 is provided at the end of the housing 1 facing away from the annular protrusion 12. The mounting plate 15 is arranged around the outer periphery of the mounting hole 11. The weighing component 4 is installed in the mounting hole 11. The weighing component 4 includes, from top to bottom, double-sided adhesive 41, support feet 42, E-shaped load cells 43, scale feet 44, and foot pads 45. The support feet 42 and scale feet 44 cooperate to fix the E-shaped load cells 43. The support feet 42 are bonded to the cover 2 by double-sided adhesive 41, and the foot pads 45 are attached to the bottom of the scale feet 44. In this embodiment, the inner wall of the mounting plate 15 is provided with multiple protrusions, and correspondingly, the outer wall of the support feet 42 is provided with multiple slots so that the mounting plate 15 and the support feet 42 can be snapped together.

[0029] See Figure 2 As shown, a battery 7 and a charging management module electrically connected to the battery 7 are installed inside the housing cavity. A charging port 13 corresponding to the battery 7 and a charging cover 14 covering the charging port 13 are provided on one side of the housing 1. This design prevents dust and small debris from accumulating in the charging port 13, thereby ensuring good contact between the charging port 13 and the charging cable and extending the service life of the smart scale.

[0030] In this embodiment, the cover 2 is made of glass.

[0031] Since fat in the human body is almost non-conductive, while muscles contain a lot of blood and water, making them highly conductive, the body's muscles serve as the conductors for current flow. By analyzing the ease with which current passes through muscles and using formulas derived from extensive experiments, the weight of the test subject's muscles can be calculated, thus determining the proportion of muscle in body weight. Specifically, fat-measuring electrodes are placed in contact with the test subject's legs and / or hands, and a safe current is applied to measure bio-impedance. Based on the input user data and the measured bio-impedance, the percentage of body fat, body water, body muscle, and bone weight can be measured relatively accurately. In other words, the ratios of body fat, water, bone, and other tissue components can be obtained by measuring bio-impedance.

[0032] See Figures 3-4 As shown, the main control unit 5 includes a front-end test module, a main control Bluetooth module, and a driver module. The front-end test module and the driver module are respectively connected to the main control Bluetooth module. The main control Bluetooth module obtains the test data output by the front-end test module and calculates human health data based on the test data. The main control Bluetooth module transmits the human health data to the driver module via the SPI bus. The output port of the driver module is connected to the color display screen 3. This embodiment does not involve any improvement to the detection method or detection program, so it is not described in detail.

[0033] It should be noted that human health data includes weight, fat, water, bones, muscles, BMI, and bone mass.

[0034] In this embodiment, the driving module is a TFT color screen driving module.

[0035] In this embodiment, the main control Bluetooth module and the TFT color screen driver module communicate via SPI and are connected via 5 wires and 2 channels to achieve data interaction at a rate of 2*30MHz. This enables the display of patterns on a color screen with a resolution of 240*RGB*320 or 320*RGB*480, and can achieve a refresh rate of up to 52 frames per second, thereby enabling smooth display of dynamic video.

[0036] In this embodiment, the main control unit 5 also includes a WIFI chip, and the WIFI chip and the main control Bluetooth module are connected via serial port UART communication.

[0037] The main control Bluetooth module and the TFT color screen driver module communicate using five signal lines, as follows:

[0038] SPI_RST: Provides a reset signal;

[0039] SPI_CS: Provides the chip select signal;

[0040] SPI_SCL: Provides clock pulse signals;

[0041] SPI_RS: Provides data channel 1 signal;

[0042] SPI_SDA: Provides data channel 2 signals.

[0043] In this embodiment, after the main control Bluetooth module operates, it receives human information data sent from the mobile app, and simultaneously receives environmental data such as weather and temperature sent from the WIFI chip. The WIFI chip can obtain the current weather, temperature, and other environmental data from the server and send the data to the main control Bluetooth module. When the lipid measurement electrode pads and the E-shaped weighing sensor 43 acquire test data (weight, impedance, heart rate) about the human body, they send it to the front-end measurement chip. The main control Bluetooth module receives the weight, impedance, and heart rate data collected by the front-end measurement chip, calculates relevant health data based on the received data, and sends the health data to the TFT color screen driver module through the 5-wire 2-channel data line of SPI. Then, the TFT color screen driver module draws colorful and personalized patterns, data, or animations on the TFT color display screen.

[0044] The present invention provides an intelligent weighing scale equipped with a color display screen, which has the following advantages compared with current weighing scales:

[0045] (1) The color display screen 3 is driven by SPI communication, which can realize high-speed data interaction, thereby achieving smooth display of dynamic video, so that the smart scale can display health data information related to the human body in the form of dynamic video.

[0046] (2) The TFT color display screen can display health data and user information in multiple colors. Moreover, the display program of the TFT color display screen can be embedded in the main control Bluetooth module to realize colorful and personalized patterns, data and animation display.

[0047] (3) The wireless upgrade status can be dynamically displayed on the TFT color display screen via Bluetooth and WiFi, and the program can be continuously updated and iterated, constantly bringing users a brand-new interface display and increasing user stickiness.

[0048] (4) Data from other health devices in the home can be obtained via Bluetooth or WIFI and displayed on the TFT color display screen, so that the TFT color display screen can be used as a terminal device for managing body health data.
