[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] This utility model discloses an intelligent body fat scale, including a scale body 1. The scale body 1 is provided with scale body electrode plates 11 for testing foot impedance. The scale body 1 is connected to a handle 2 via a cable. The handle 2 is provided with handle electrode plates 21 for testing hand impedance. The scale body 1 is also provided with a processor 12 that can calculate body fat percentage through impedance information and a first wireless communication device 13 electrically connected to the processor 12. A display 3 is detachably connected to the handle 2. The display 3 includes a second wireless communication device 31 that is communicatively connected to the first wireless communication device 13 to receive body fat percentage information and a display screen 32 for displaying body fat percentage information.

[0024] The scale body 1 is used to support the user's weight and integrates a weighing sensor to measure the user's weight data. The upper surface of the scale body 1 is provided with scale body electrode plates 11. When the user stands barefoot on the scale body 1, their feet contact the scale body electrode plates 11, thus forming foot electrodes for bioelectrical impedance measurement. The handle 2 is provided with handle electrode plates 21. When the user holds the handle 2 with both hands, their palms contact the handle electrode plates 21, thus forming hand electrodes for bioelectrical impedance measurement. Through the scale body electrode plates 11 and the handle electrode plates 21, more comprehensive body impedance data can be obtained.

[0025] In this embodiment, the handle 2 is connected to the internal circuitry of the scale body 1 via a cable disposed on the scale body 1. The cable can be connected to a reel or be a spring-loaded cable, allowing the cable to extend or retract relative to the scale body 1. The cable contains electrical wires, and the handle surface is provided with four handle electrode plates 21, which are electrically connected to the cable.

[0026] The scale body 1 also integrates a processor 12, which receives bioelectrical impedance signals measured by the scale body electrode pads 11 and the handle electrode pads 21, and calculates information such as the user's body fat percentage and muscle mass according to a preset bioelectrical impedance analysis algorithm. In this embodiment, the processor 12 has a measurement circuit for generating excitation signals and collecting impedance signals from the electrodes. The processor 12 is also electrically connected to a first wireless communication device 13, which transmits the body composition information such as body fat percentage calculated by the processor 12 to the outside in the form of wireless signals. In this embodiment, by integrating the processor 12 and the first wireless communication device 13 on a microcontroller, the entire measurement process, data processing, and communication are controlled. The handle 2 is provided with a detachable display 3, which integrates a second wireless communication device 31. The second wireless communication device 31 and the first wireless communication device 13 on the scale body 1 can form a wireless communication pairing relationship via Bluetooth or Wi-Fi, and can receive the body fat percentage information transmitted by the first wireless communication device 13. The display 3 also includes a display screen 32, which can be any display module, such as LCD or LED. The detachable design of the display 3 facilitates future upgrades, allowing for easy replacement of the LCD screen, LED screen, or touchscreen. The display screen 32 is electrically connected to the second wireless communication device 31. The received body fat percentage information is processed and then displayed visually on the display screen 32.

[0027] By making the display 3 and the handle 2 detachable, it is convenient for users to view the measurement during the measurement process. After the measurement is completed, users can remove the display 3 from the handle 2 and hold it in front of their eyes or place it in a more comfortable position to view the measurement, which improves the convenience and experience of operation.

[0028] In this embodiment, the first wireless communication device 13 can also connect and communicate with external smart devices such as mobile phones, and display relevant data on the external smart devices.

[0029] In this embodiment, the display 3 also includes a power module, microprocessor, operation buttons, and storage module independent of the scale body 1. The display 3 also provides a stable operating voltage to the internal electronic components of the display 4 via the power module. Furthermore, the power module includes a rechargeable battery, and the display 3 has a charging interface to replenish the battery. Since the scale body 1 lacks the power-consuming components of the display 3, its battery life is extended. The display 3, being detachable and small, is convenient for charging and carrying. The storage module stores the data transmitted by the scale body locally, allowing users to browse historical measurement data, trend charts, or configure device settings via the operation buttons. Because the display 3 has its own power supply and related hardware, it can also interconnect with smart kitchen scales and other related products to display and store relevant information.

[0030] The handle 2 has a mounting groove 22 that can accommodate the front of the display 3, and a detachable connection structure 4 is provided between the front of the display 3 and the mounting groove 22. The depth and outline of the mounting groove 22 match the shape of the front of the display 3. When the display 3 is installed in place, its front is embedded in the mounting groove 22, forming a stable physical position.

[0031] In the embodiment, the detachable connection structure 4 adopts a snap-fit ​​structure, or it can also adopt a threaded connection, magnetic connection or other methods to achieve the detachable connection between the two.

[0032] The detachable connection structure 4 includes a slot 221 provided on the side wall of the mounting groove 22, and a limiting block 51 slidably provided on the display 3 so as to be able to extend into the slot 221. The limiting block 51 is connected to a linkage 52, which at least partially extends to the outside of the display 3 for user operation to drive the limiting block 51 to slide.

[0033] A slot 221 is provided on the inner wall of the mounting groove 22. The slot 221 is a recessed groove-shaped structure, which can be rectangular or other shapes, used to accommodate and restrict the movement of the limiting block 51 when the display 3 is installed in place, thereby achieving mechanical locking. The limiting block 51 is slidably mounted on the display 3 and can reciprocate in a specific direction. When the display 3 is pushed into the mounting groove 22, the limiting block 51 can align with the slot 221 and extend into the slot 221 to achieve locking and prevent the display 3 from falling out. At least a portion of the linkage 52 extends to the outside of the display 3 to form an operating part for user operation. In this embodiment, the operating part is a button, but it can also be a lever or other forms. The operating part is located on the side or top of the display 3, or in a position easily accessible to the fingers. When the user needs to disassemble the display 3, he / she presses or moves the operating part of the extended linkage 52 with his / her fingers. The operating force is transmitted to the limit block 51 through the linkage 52, causing the limit block 51 to slide out of the slot 221, thereby releasing the mechanical lock between the display 3 and the handle 2. At this time, the user removes the display 3 from the mounting slot 22.

[0034] The limiting block 51 is connected to a first elastic element 53 that pushes it toward the slot 221. When the limiting block 51 is in the initial state, the first elastic element 53 is in a compressed or stretched state, thereby continuously applying a spring force toward the slot 221 to the limiting block 51, thereby realizing the automatic locking function of the limiting block 51 during the installation of the display 3.

[0035] The side of the linkage 52 away from the limiting block 51 is connected to a second elastic element 54.

[0036] When the first elastic element 53 applies a continuous pushing force toward the slot 221 to the limiting block 51, the linkage 52 may rotate and shift during the sliding of the limiting block 51. By connecting a second elastic element 54 to the side of the linkage 52 away from the limiting block 51, a structure with balanced forces at both ends is formed, ensuring that the linkage 52 and the limiting block 51 slide smoothly along the preset track.

[0037] The first elastic element 53 and the second elastic element 54 can be made of components such as springs and sheet metal.

[0038] The linkage 52 is connected to a guide plate 55, the guide plate 55 has a guide groove 551, and the display 3 is provided with a guide protrusion 33 that extends into the guide groove 551.

[0039] A guide groove 551 is provided on the guide plate 55. In this embodiment, the guide groove 551 is a long strip-shaped through groove, the extension direction of which is parallel to the expected sliding direction of the limiting block 51. A guide protrusion 33 is provided on the display 3. The axis of the guide protrusion 33 is perpendicular to the sliding direction of the linkage 52 and forms a sliding fit with the inner wall of the guide groove 551, thereby limiting the lateral displacement of the linkage 52 and ensuring the accuracy and stability of the movement.

[0040] The display 3 is provided with limiting blocks 51 on both the left and right sides, and the slots 221 are provided on the left and right sides of the mounting slot 22 and are correspondingly set with the limiting blocks 51. When the display 3 is pushed into the mounting slot 22, the limiting block 51 on the left side aligns with and is inserted into the slot 221 on the left side of the mounting slot 22, while the limiting block 51 on the right side aligns with and is inserted into the slot 221 on the right side, realizing dual-point synchronous locking and restricting the display 3 from rotating or tilting during use or insertion / removal.

[0041] The limit block 51 and the linkage 52 are integrally molded, which simplifies the assembly process and improves the structural strength and reliability.

[0042] The monitor 3 has a support structure 34 at the rear. When the monitor 3 is detached from the handle 2, it can be placed independently on a flat surface such as a desktop using the support structure 34, making it convenient for users to remotely view data, browse history records, or perform device settings.

[0043] In this embodiment, the support structure 34 is a support frame hinged to the rear of the display 3. The hinged connection allows the support frame to rotate within a certain angle range relative to the display 3, enabling the display 3 to have both unfolded and folded states for storage. When the support frame is unfolded, one end acts as a fulcrum contacting the support surface, while the other end connects to the display 3, forming a stable triangular support structure that keeps the display 3 tilted to present a suitable viewing angle. When the support frame is folded, it fits snugly against the rear of the display 3, reducing the overall volume and facilitating storage and portability. The support structure 34 can also be implemented using a folding bracket, a snap-on bracket, or a support groove, etc.

[0044] The handle 2 is provided with a magnetic component 23, and the scale body 1 is provided with a Hall sensor 14 at the corresponding position. The Hall sensor 14 is electrically connected to the processor 12.

[0045] In this embodiment, the processor 12 is pre-programmed with mode switching control logic. When the handle 2 is placed on the scale body 1, the Hall sensor 14 detects a magnetic field signal, and the processor 12 determines that the handle 2 has not been lifted, thus enabling the four-electrode measurement mode, using only the four scale body electrode plates 11 on the scale body for measurement. When the user lifts the handle, and the Hall sensor 14 does not detect a magnetic field signal, the processor 12 determines that the handle 2 is in use, thus enabling the eight-electrode measurement mode, using both the scale body electrode plates 11 and the handle electrode plates 21 for measurement. This meets the user's measurement needs in different scenarios.
