Description

Technical Field

[0001] The utility model relates to the field of body fat scales, and particularly relates to a body fat scale with a connecting wire steering structure. Background Art

[0002] The eight-electrode body fat scale applies the principle of BIA bioelectrical impedance measurement to measure the impedance information of corresponding segments of the human body by measuring the response of the human body to weak alternating current, and then analyzes various components of the human body; since the alternating current input by the overall scheme is very weak, during the measurement process, the change of the conduction impedance of the device itself has a great influence on the final measurement result.

[0003] For the eight-electrode measurement scheme, the user needs to hold 4 electrodes with the hand and contact 4 electrodes with the leg. Among them, one end of the electrode on the leg or hand must be directly led out by a longer wire and connected to the main board; and in order to improve the user experience, a wire reel scheme is extended to retract and store this wire; however, the eight-electrode products with this structure have the following disadvantages:

[0004] 1. The wire reel scheme applied is generally a double-layer wire reel scheme. Due to reasons such as the structural strength and size space of this scheme, the wire used is generally a round wire. In order to save the overall size space, the wires need to be twisted together inside. Considering the actual use requirements of the product, the telescopic length is generally more than 1.5 meters, and the total length of the flat wire needs to reach more than 2.5 meters. After the wires are twisted together, it is easy to cause fluctuations in parasitic capacitance, thus causing fluctuations in the overall measurement result;

[0005] 2. If the round wire is adjusted to a flat wire scheme, the wire cores can be arranged side by side. Although this method can effectively reduce the interference inside the wire cores and maintain the stability of the body fat measurement of the product; however, due to the influence of its shape, the flat wire scheme cannot effectively control the deflection direction of the flat wire after it exits the wire reel. After long-term use, the wire will be twisted multiple times, resulting in changes in body fat measurement, and even the risk of the wire being directly broken;

[0006] Therefore, there is an urgent need for a body fat scale with a connecting wire steering structure to solve the above problems. Summary of the Utility Model

[0040] Refer to Figures 1 to 6, A body fat scale with a connecting wire steering structure, including a handle 100, a scale body 200, a control board 300, and a wire reel 400. The control board 300 is arranged inside the scale body 200, and the wire reel 400 is rotatably arranged inside the scale body 200.

[0041] 1) Refer to Figures 1-2 , There are 4 first electrodes 110 arranged on the handle 100, 4 second electrodes 210 arranged on the scale body 200, and 4 weight sensors evenly distributed at the bottom of the scale body 200. When measuring, the user stands on the scale body 200, holds the handle 100 with both hands, detects the impedance of the user's upper body through the 4 first electrodes 110 on the handle 100, detects the impedance of the user's lower body through the 4 second electrodes 210 on the scale body 200, and detects the weight of the user through the 4 weight sensors on the scale body 200. All parameters are transmitted to the control board 300 for summarization and analysis, and finally the body fat parameters of the user are obtained.

[0042] 2) In one embodiment, it further includes a flat wire 500 and a steering assembly 600; One end of the flat wire 500 is connected to the handle 100, and the other end extends into the scale body 200 and is connected to the wire reel 400. The flat wire 500 can be wound up on the wire reel 400 or unwound from the wire reel 400; The steering assembly 600 is arranged inside the scale body 200 and / or at the wire outlet end of the wire reel 400. When the flat wire 500 passes through it, the steering assembly 600 can force the flat wire 500 to deflect, so that the flat wire 500 is adjusted from being arranged in the vertical direction to being arranged in the horizontal direction;

[0043] Specifically, when the handle 100 is pulled out, it will drive the flat wire 500 to pull the wire reel 400 to rotate, and then the flat wire 500 originally wound on the wire reel 400 will be gradually unwound. It should be noted that the flat wire 500 is arranged vertically on the wire reel 400, that is, the flat wire 500 is perpendicular to the upper end face of the scale body 200. After being controlled by the deflection of the steering assembly 600, it will be adjusted to the horizontal state, that is, the flat wire 500 is parallel to the upper end face of the scale body 200.

[0044] 3) As a preferred embodiment of the steering assembly 600, the steering assembly 600 includes a first deflection member 610 and a second deflection member 620;

[0045] The first deflection member 610 is arranged inside the scale body 200 or at the wire outlet end of the wire reel 400. When the flat wire 500 passes through it, the first deflection member 610 can force the flat wire 500 to deflect once;

[0046] The second deflection member 620 is arranged at the wire outlet end of the scale body 200. When the flat wire 500 passes through it, the second deflection member 620 can force the flat wire 500 to deflect twice;

[0047] The flat wire 500 can be adjusted from being arranged in a vertical direction to being arranged in a horizontal direction under the adjustment of the first deflection member 610 and the second deflection member 620;

[0048] Specifically, the first deflection member 610 serves as the first section of the turning adjustment of the flat wire 500 when passing through the outlet end of the wire drum 400, and limits the normal deflection direction of the flat wire 500. The direction of the outlet end of the wire drum 400 only needs to have a clear deflection inclination angle, and the size is controlled so that the flat wire 500 will not return to the vertical state when passing through the first deflection member 610. It does not limit whether it is independently nested or directly adjusted on the surface and bottom shell of the wire drum 400, and does not limit the angle; the deflection of the wire drum 400 is divided into two sections of turning (the first deflection member 610 and the second deflection member 620). Preferably, the deflection angle of the flat wire 500 after passing through the first deflection member 610 is 45°; and when the body fat scale is used, the handle 100 needs to be pulled up vertically. Therefore, the second deflection member 620 is set as a turning point from the vertical direction. When it is pulled up at the second deflection member 620, due to the influence of force, the final direction of the flat wire 500 is controlled to be fixed during normal use.

[0049] 4) In a further embodiment, the first deflection member 610 includes a deflection seat 611 arranged in the scale body 200 or at the outlet end of the wire reel 400, and the deflection seat 611 is provided with an inclined deflection hole 612, and the flat wire 500 is passed through the deflection hole 612; the second deflection member 620 is configured as a guide wheel 621 rotatably connected to the outlet end of the scale body 200, the rotation axis of the guide wheel 621 is arranged in the horizontal direction, and the flat wire 500 is wound around the guide wheel 621.

[0050] Specifically, the deflection seat 611 is used as the first stage of steering, and is preferably arranged at the outlet end of the line drum 400. The guide wheel 621 is rotatably connected to the scale body 200 through a rotating shaft structure, and is used as the second stage of steering, ultimately realizing the adjustment of the flat wire 500 from being arranged in the vertical direction to being arranged in the horizontal direction.

[0051] 5) In a further embodiment, a body fat scale with a connecting line steering structure further includes a first conductive component 710, a second conductive component 720 and a self-locking component 800;

[0052] The first conductive component 710 is disposed in the scale body 200 and connected to the control board 300;

[0053] The second conductive component 720 is disposed on the wire drum 400 and connected to the other end of the flat wire 500. The second conductive component 720 contacts the first conductive component 710 to maintain electrical connection when the wire drum 400 rotates relative to the scale body 200.

[0054] The self-locking assembly 800 is connected between the wire reel 400 and the weighing body 200, and is used to limit the movement of the wire reel 400 relative to the weighing body 200;

[0055] Specifically, the first conductive component 710 and the second conductive component 720 can always maintain electrical connection when the wire reel 400 rotates relative to the weighing body 200, so that the signal collected by the handle 100 is sent to one end of the flat wire 500, and is transmitted to the control board 300 through the flat wire 500, the second conductive component 720, and the first conductive component 710. Then, combined with the signals transmitted by the 4 second electrodes 210 on the weighing body 200, the summary and analysis of the data are realized.

[0056] 6) As a preferred embodiment of the self-locking assembly 800, the self-locking assembly 800 includes a clamping member 810 and a ratchet wheel 820. The ratchet wheel 820 is rotatably arranged on the weighing body 200 and is provided with a first abutting portion 830 and a second abutting portion 840 thereon. The clamping member 810 is arranged on the weighing body 200 and is provided with a third abutting portion 850 thereon. The wire reel 400 is provided with a fourth abutting portion 860;

[0057] The first abutting portion 830 can abut against the fourth abutting portion 860 when the second abutting portion 840 is on one side of the third abutting portion 850, so as to limit the rotation of the wire reel 400 relative to the weighing body 200;

[0058] The first abutting portion 830 can be separated from the fourth abutting portion 860 when the second abutting portion 840 is on the other side of the third abutting portion 850, so that the wire reel 400 can rotate relative to the weighing body 200;

[0059] Specifically, when the user pulls out the handle 100, the wire reel 400 will be driven to rotate through the flat wire 500. The first abutting portion 830 on the ratchet wheel 820 first abuts against the fourth abutting portion 860 on the wire reel 400, thereby restricting the rotation of the wire reel 400 relative to the weighing body 200. When the user continues to apply force, the second abutting portion 840 on the ratchet wheel 820 will be on the other side of the third abutting portion 850, so that the first abutting portion 830 on the ratchet wheel 820 is separated from the fourth abutting portion 860, that is, the restriction of the first abutting portion 830 on the fourth abutting portion 860 is released, and the wire reel 400 can rotate relative to the weighing body 200. When the ratchet wheel 820 is driven in the reverse direction so that the second abutting portion 840 reversely crosses and is on one side of the third abutting portion 850, it will abut against the fourth abutting portion 860 on the wire reel 400 again, and the rotation of the wire reel 400 relative to the weighing body 200 will be restricted again, realizing "self-locking".

[0060] 7) In one embodiment, the card member 810 is provided as a U-shaped elastic piece 811, the third abutting portion 850 is disposed on the inner wall of the U-shaped elastic piece 811, the second abutting portion 840 can abut against one side of the third abutting portion 850, or when the U-shaped elastic piece 811 is deformed, cross over and be located on the other side of the third abutting portion 850; the movement of the ratchet wheel 820 will push and deform the connecting arm where the third abutting portion 850 on the U-shaped elastic piece 811 is located, so that the first abutting portion 830 can cross over the third abutting portion 850 and enter the other side of the third abutting portion 850.

[0061] 8) It should be noted that the self-locking assembly 800 can also adopt a ball-type self-locking mechanism, a spring piece-type self-locking mechanism, etc., which will not be elaborated here and should not be regarded as a limitation to the present utility model; the advantages of the present utility model are as follows: 1. Through the above structure, not only can the wire reel be a single-layer structure, greatly reducing the thickness of the weighing body, but the self-locking assembly can lock after the connecting wire is pulled out, thereby ensuring the stability of the electrical signal transmission and helping to improve the measurement accuracy; 2. By the steering assembly, the angle of the flat wire can be deflected, that is, adjusted from being arranged in the vertical direction to being arranged in the horizontal direction, which can ensure that when the handle is pulled out, the flat wire can be smoothly turned horizontally, and the overall rotation direction can be controlled to avoid the situation of over-twisting of the flat wire during normal use.

[0062] Preferably, the deflection seat 611 is connected to the inside of the weighing body 200 or disposed at the wire outlet end of the wire reel 400 through a clamping structure 630.

[0063] As a preferred embodiment of the first conductive assembly 710, the first conductive assembly 710 is provided as a brush disc or a slip ring

[0064] As a preferred embodiment of the second conductive assembly 720, the second conductive assembly 720 is provided as a spring pin or a spring piece.

[0065] In one embodiment, a body fat scale with a connecting wire steering structure further includes a connecting member 940 having a mounting portion 960 and a limiting portion 950. A through hole 930 through which the mounting portion 960 can pass is provided on the ratchet wheel 820. The limiting portion 950 can abut against the ratchet wheel 820 when the mounting portion 960 is connected to the weighing body 200 to limit the separation of the ratchet wheel 820 from the weighing body 200.

[0066] In one embodiment, the wire cores in the flat wire 500 are arranged along the width direction of the flat wire 500; the wire reel provided by the present utility model is a single-layer structure, which can have enough space to adjust the traditional round wire into a flat wire; in practical applications, for the convenience of users, usually the wire length needs to meet the requirement of stretching 1.5 meters, and the total length is close to 3 meters. The flat-type flat wire 500 can be made relatively wide, and the wire cores do not need to be wound around each other, and the measurement result will be more stable, avoiding the parasitic capacitance fluctuation generated by the wire after the circular flat wire 500 is wound.

[0067] A body fat scale with a connecting wire turning structure further includes an upper cover 910 and a lower cover 920 connected to the upper cover 910 through a detachable structure. The upper cover 910 and the lower cover 920 together enclose an accommodation space for accommodating a wire reel 400, a first conductive component 710, a second conductive component 720, and a self-locking component 800. This setting enables the upper cover 910, the lower cover 920, the wire reel 400, the first conductive component 710, the second conductive component 720, and the self-locking component 800 to form a wire reel assembly, which can then be directly assembled onto the scale body 200, improving the assembly efficiency and reducing the assembly difficulty.

[0068] As a first embodiment of the detachable structure, the detachable structure is provided as a snap-fit structure.

[0069] As a second embodiment of the detachable structure, the detachable structure is provided as a bolt connection structure.
