DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0031] like Figure 1 and Figure 2 As shown, the human body composition analysis device provided by an embodiment of the present invention includes: a support plate 100, a control plate, a flexible conductive medium 200 and a plurality of measuring electrodes. The plurality of measuring electrodes are all arranged on the supporting surface of the support plate 100, and each measuring electrode is connected to the control plate through at least two flexible conductive media 200.

[0032] Specifically, the support plate 100 is made of glass, and the flexible conductive medium 200 is a conductive adhesive, conductive ink, or conductive cloth. In this embodiment, the flexible conductive medium 200 is conductive cloth. There are four or eight measuring electrodes, each of which is disposed on the support surface of the support plate 100. The control board is located on the side of the support plate 100 facing away from the support surface. The multiple measuring electrodes are electrically connected to the control board via at least two flexible conductive mediums 200. This prevents static electricity from concentrating on the flexible conductive medium 200 during passage, effectively improving the overload capacity of the flexible conductive medium 200 and making it less susceptible to breakdown, thereby enhancing the stability of the fat measurement function.

[0033] Furthermore, when the measuring electrode is connected to the control board through at least two flexible conductive media 200 , at least one corresponding end of the plurality of flexible conductive media 200 is an integrated structure.

[0034] Specifically, the ends of the multiple flexible conductive media 200 are integrally structured, or the ends of the multiple flexible conductive media 200 connected to the measuring electrodes are integrally structured, or the ends of the multiple flexible conductive media 200 connected to the control board are integrally structured. In this embodiment, the ends of the multiple flexible conductive media 200 connected to the measuring electrodes are separate structures, while the ends connected to the control board are integrally structured. Specifically, the entire flexible conductive media 200 can be split in the middle to form multiple flexible conductive media 200 with one end integral and the other end separate. When the ends of the multiple flexible conductive media 200 are connected to the measuring electrodes and the control board respectively, the independent ends of the multiple flexible conductive media 200 are connected to the side of the support plate 100 to prevent static electricity from concentrating on the flexible conductive media 200 when passing through. By connecting the integral structure of the other end to the control board, the multiple flexible conductive media 200 can be connected to the control board, thereby facilitating operation.

[0035] Furthermore, the measuring electrode includes an ITO (Indium Tin Oxides) coating layer.

[0036] Specifically, multiple areas on the support surface are provided with an ITO coating layer 310 to form multiple measuring electrodes. The multiple ITO coating layers 310 are electrically connected to the control board through a flexible conductive medium 200. ITO is an N-type oxide semiconductor - indium tin oxide. The ITO film is an indium tin oxide semiconductor transparent conductive film, which usually has two performance indicators: resistivity and transmittance. Using the ITO coating layer 310 as a measuring electrode can achieve measurement while improving the aesthetics of the human body composition analysis device provided by the embodiment of the present invention.

[0037] Furthermore, the ITO coating layer 310 includes an extension portion 311 disposed on a side surface of the support plate 100 , and one end of the flexible conductive medium 200 is connected to the extension portion 311 .

[0038] like Figure 3 As shown, each ITO coating layer 310 includes an extension 311. Part of the extension 311 of the ITO coating layer 310 is located on the first side of the support plate 100, while another part of the extension 311 of the ITO coating layer 310 is located on the second side of the support plate 100. The first and second sides are parallel to each other. Specifically, ITO can be plated on the side of the support plate 100 using a target winding plating method to serve as the extension 311 of the ITO coating layer 310. Each extension 311 is connected to one end of a corresponding flexible conductive medium 200, thereby connecting the measuring electrode to the control board. Each ITO coating layer 310 extends to the side of the support plate 100. By connecting the flexible conductive medium 200 to the extension 311 on the side of the support plate 100, it can be connected to the corresponding measuring electrode. This eliminates the need to drill holes in the support plate 100 or extend the flexible conductive medium 200 to the support surface, saving processing steps. The resulting human body composition analysis device has an aesthetically pleasing appearance and the support plate 100 has a high strength.

[0039] In some embodiments, the flexible conductive medium 200 can be mounted on the support plate 100 via fasteners to abut against the extension portion 311 , or connected to the extension portion 311 by bonding. In this embodiment, the flexible conductive medium 200 is bonded to the extension portion 311 by conductive adhesive.

[0040] Specifically, the side of the flexible conductive medium 200 opposite the extension 311 is coated with conductive adhesive. The flexible conductive medium 200 is bonded to the side of the support plate 100 opposite the extension 311 via the conductive adhesive, thereby securing one end of the flexible conductive medium 200 and electrically connecting it to the measuring electrode. The flexible conductive medium 200 is connected to the extension 311 via the conductive adhesive, eliminating the need for additional metal electrode materials to achieve connection to the measuring electrode. This reduces the amount of metal electrode materials and assembly steps, lowering material and labor costs, and thus lowering the production cost of the human body composition analysis device provided by the embodiments of the present invention.

[0041] Furthermore, a conductive coating is provided on the side of the extension 311 opposite the flexible conductive medium 200. The conductive coating can be a conductive silver ink layer, which can be processed onto the extension 311 by silk screen printing. The provision of the conductive coating improves the stability of the ITO coating layer 310 on the supporting side.

[0042] In some embodiments, the flexible conductive medium 200 is connected to the control board via a wire. Specifically, one end of the wire is connected to the flexible conductive medium 200 by welding, and the other end is connected to the control board by welding, thereby forming a closed loop to achieve body impedance measurement.

[0043] like Figure 4 and Figure 5 As shown, the human body composition analysis device provided by the embodiment of the present invention further includes a connecting electrode 400 , which abuts against an end of the flexible conductive medium 200 away from the measuring electrode and is connected to the control board via a wire.

[0044] The number of connecting electrodes 400 is equal to the number of measuring electrodes. The multiple connecting electrodes 400 are all located on the side of the support plate 100 facing away from the support surface and are connected to the multiple measuring electrodes one-to-one through the flexible conductive medium 200. Specifically, the flexible conductive medium 200 connecting different measuring electrodes is independent of each other. Taking the connection method of one group of measuring electrodes and the connecting electrodes 400 as an example for specific description, one end of the flexible conductive medium 200 is connected to the extension portion 311 of the measuring electrode via conductive adhesive. The middle portion of the flexible conductive medium 200 is bent toward the side of the support plate 100 facing away from the support plate 100 and adheres to the side of the support plate 100 facing away from the support surface. The connecting electrode 400 abuts against the end of the flexible conductive medium 200 away from the extension portion 311 and is connected to the control board via a wire, thereby connecting the flexible conductive medium 200 and the control board, forming a closed loop and achieving body impedance measurement. The flexible conductive medium 200 is connected to the control board via the connecting electrode 400 . The connecting electrode 400 abuts against the flexible conductive medium 200 to avoid damage to the flexible conductive medium 200 , thereby improving the stability of the connection between the flexible conductive medium 200 and the control board.

[0045] Furthermore, the connecting electrode 400 includes a mounting seat 410 and an elastic connecting member. The elastic connecting member is mounted on the mounting seat 410 and abuts against the flexible conductive medium 200 .

[0046] Specifically, the mounting base 410 can be mounted on the support plate 100 by means of snap connection or bonding, and the elastic connecting member is located between the mounting base 410 and the support plate 100. Figure 6 and Figure 7 As shown, the human body composition analysis device provided by the embodiment of the present invention also includes a face shell 500. The face shell 500 is located on the side of the support surface away from the support plate 100 and is connected to the support plate 100 by a snap-fitting manner. The mounting seat 410 is detachably mounted on the face shell 500. The elastic connector is mounted on the mounting seat 410 and abuts against the flexible conductive medium 200. One end of the wire is connected to the elastic connector and the other end is connected to the control board. The flexible conductive medium 200 is connected to the control board via the elastic connector. The elastic restoring force of the elastic connector improves the stability of the connection between the elastic connector and the flexible conductive medium 200. When abutting against flexible conductive media 200 of different thicknesses, the elastic connector will produce different elastic deformations, thereby avoiding the problem of the support plate 100 being lifted due to a rigid connection.

[0047] The elastic connecting member includes an elastic metal sheet or a coil spring 420, such as Figure 8 As shown, in this embodiment, the elastic connecting member includes a coil spring 420 , a first end of the coil spring 420 is connected to the mounting seat 410 , and a second end of the coil spring 420 is provided with a coil surface 421 for abutting against the flexible conductive medium 200 .

[0048] The coil spring 420 is located between the mounting base 410 and the support plate 100, with one end fixedly mounted to the mounting base 410. The axis of the coil spring 420 is perpendicular to the support plate 100, so that the force exerted by the coil spring 420 on the flexible conductive medium 200 is more balanced. The elastic connector includes the coil spring 420, which has a greater elastic deformation, thereby being able to abut against a wider range of flexible conductive media 200 with different thicknesses. In addition, the first end of the coil spring 420 is connected to the mounting base 410, and the second end of the coil spring 420 is provided with a spiral surface 421 for abutting against the flexible conductive medium 200, thereby increasing the contact area between the coil spring 420 and the flexible conductive medium 200 and improving the stability of the connection between the two.

[0049] Specifically, the mounting base 410 can be connected to the face shell 500 by means of a snap connection or a threaded connection. In this embodiment, the mounting base 410 is connected to the face shell 500 by a snap connection. Specifically, the mounting base 410 is located on the side of the face shell 500 that faces away from the support plate 100. The face shell 500 is provided with a through hole for the coil spring 420 to pass through. The side of the face shell 500 that faces away from the support plate 100 is provided with a limiting member 510 that is arranged opposite to the through hole. A snap connection groove that cooperates with the mounting base 410 is formed between the limiting member 510 and the face shell 500. An elastic clip 411 is provided on the side of the mounting base 410 opposite to the face shell 500. When the mounting base 410 is installed on the face shell 500, the mounting base 410 is snapped into the slot, and the elastic clip 411 produces elastic deformation, which increases the mutual force between the mounting base 410 and the face shell 500, thereby improving the installation stability of the mounting base 410. The mounting base 410 is installed on the face shell 500 by snapping, which facilitates the installation of the mounting base 410.

[0050] Furthermore, the human body composition analysis device further includes a bottom shell 600 , which is located on a side of the surface shell 500 facing away from the support plate 100 and is connected to the surface shell 500 .

[0051] The bottom shell 600 can be connected to the face shell 500 by means of a snap connection or a threaded connection. In this embodiment, the bottom shell 600 is connected to the face shell 500 by snap connection. Specifically, a slot is provided on the side of the face shell 500 facing away from the support plate 100, and the bottom shell 600 is snapped into the slot, thereby achieving the connection between the bottom shell 600 and the face shell 500. The bottom shell 600 covers the various components on the face shell 500, thereby playing a protective role.

[0052] The human body composition analysis device provided by an embodiment of the present invention includes: a support plate 100, a control board, a flexible conductive medium 200, and multiple measuring electrodes. The multiple measuring electrodes are all arranged on the support surface of the support plate 100, and each measuring electrode is connected to the control board via at least two flexible conductive media 200. When a user uses the human body composition analysis device provided by an embodiment of the present invention, their feet contact the measuring electrodes on the support plate 100. The measuring electrodes transmit current to the control board via the flexible conductive medium 200. The control board analyzes and displays the detection data. The measuring electrodes are connected to the control board via at least two flexible conductive media 200, thereby preventing static electricity from concentrating on the flexible conductive medium 200 when it passes through, effectively improving the overload capacity of the flexible conductive medium 200, making the flexible conductive medium 200 less likely to be broken down, thereby improving the stability of the fat measurement function.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
