[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] Example: Refer to Figure 1-Figure 15 A multifunctional human body weighing device comprises a mounting frame 1 and a display 2 fixedly mounted on the mounting frame 1, and further comprises: a first connecting seat 5 and a second connecting seat 6 which are lifted and lowered on the mounting frame 1, and the first connecting seat 5 and the second connecting seat 6 are symmetrically arranged; weighing sensors 7 are fixedly mounted on the first connecting seat 5 and the second connecting seat 6, and a third connecting seat 8 and a fourth connecting seat 9 are fixedly mounted on the tops of the two groups of weighing sensors 7 respectively; an aluminum alloy frame 29 is rotatably mounted on the third connecting seat 8 and the fourth connecting seat 9, a weighing plate 32 is fixedly mounted on the bottom of the side wall of the aluminum alloy frame 29, and an anti-cross-infection component is rotatably mounted on the weighing plate 32 and the aluminum alloy frame 29; a lifting drive unit is arranged on the mounting frame 1, and an output end of the lifting drive unit is fixedly connected to the second connecting seat 6; a rotating drive unit is arranged on the first connecting seat 5, and an output end of the rotating drive unit is fixedly connected to the aluminum alloy frame 29.

[0037] In this embodiment, the display 2 is used to display the measurement data of the device. The lifting drive unit and the rotating drive unit can also be controlled by the control module of the display 2, so as to select the corresponding weighing measurement mode according to the state of the person being weighed. The specific selection mode is as follows:

[0038] 1. When weighing a person who can stand, the weighing plate 32 is parallel to the ground, and the ground of the weighing plate 32 is 10CM-25CM away from the ground, so that the user can stand on the weighing plate 32;

[0039] Second, when weighing and measuring a person who is inconvenient to stand, the weighing plate 32 is parallel to the ground, and the lifting drive unit drives the weighing plate 32 to rise, so that the patient sitting on the weighing plate 32 is off the ground;

[0040] 3. When weighing a person who is unable to sit or stand, the rotating drive unit drives the aluminum alloy frame 29 to rotate 90 degrees, and the lifting drive unit drives the aluminum alloy frame 29 to descend.

[0041] To sum up, in this embodiment, the human body scale can select the corresponding weighing and measuring mode according to the physical state of the weighing and measuring person, that is, a person who can stand normally can choose the standing mode, so that the person stands on the weighing plate 32 for weighing and measuring, and a person who can sit but cannot stand can choose the sitting mode, that is, the weighing plate 32 is driven by the lifting drive component to make the legs and feet of the person sitting on the weighing plate 32 leave the ground, so as to measure the weight while sitting on the weighing plate 32. When there is a person who can neither stand nor sit down, the rotating drive component can be started to drive the aluminum alloy frame 29 to flip ninety degrees, so that the person who needs to be weighed and measured can lie on the aluminum alloy frame 29 to complete the weighing and measurement.

The lifting drive unit includes a second mounting plate 26 fixedly installed on the back of the mounting frame 1 and a first mounting plate 24 fixedly installed on the top of the mounting frame 1, and a screw rod 27 is rotatably installed on the first mounting plate 24 and the second mounting plate 26, and the screw rod 27 is threadedly connected to the second connecting seat 6, and a second motor 25 is fixedly installed on the first mounting plate 24, and the output shaft of the second motor 25 is transmission-connected to the screw rod 27 through a bevel gear set 28.

[0043] In this embodiment, when the second motor 25 is started, the second motor 25 drives the screw rod 27 to rotate, and the screw rod 27 drives the second connecting seat 6 to slide along the first guide rail 3, thereby driving the aluminum alloy frame 29 to rise and fall, thereby realizing the conversion of the standing weighing measurement mode and the sitting weighing measurement mode of the human body scale.

[0044] Reference Figure 1-Figure 8 The rotary driving part includes an angle iron 15 fixedly mounted on the bottom of the first connecting seat 5, a first motor 16 is fixedly mounted on the angle iron 15, a spline sleeve shaft 17 is fixedly mounted on the output end of the first motor 16, a first rotating shaft 11 is rotatably mounted on the third connecting seat 8, a worm gear 12 is fixedly mounted on the first rotating shaft 11, and the first rotating shaft 11 is fixedly mounted on the aluminum alloy frame 29, a worm 13 is rotatably mounted on the third connecting seat 8, the worm 13 is meshed with the worm gear 12, a spline shaft 14 is fixedly mounted on the bottom of the worm 13, and the spline shaft 14 is slidably connected with the spline sleeve shaft 17.

[0046] Reference Figure 1-Figure 8 A second rotating shaft 19 is rotatably mounted on the fourth connecting seat 9, and the second rotating shaft 19 is fixedly mounted on the aluminum alloy frame 29. A chuck 20 is fixedly mounted on the second rotating shaft 19, and two card slots 21 are provided on the chuck 20, and the two card slots 21 are perpendicular to each other at 90°. An electromagnetic telescopic rod 22 is fixedly mounted on the fourth connecting seat 9, and a card block 10 is fixedly mounted on the output end of the electromagnetic telescopic rod 22, and the card block 10 is inserted into the card slot 21. A fixed plate 23 is fixedly mounted on the fourth connecting seat 9, and the fixed plate 23 is slidably connected to the movable rod of the electromagnetic telescopic rod 22.

[0047] Before the rotation drive assembly is started, the electromagnetic telescopic rod 22 drives the block 10 to descend, so that the block 10 is separated from the slot 21, and then the rotation drive assembly drives the aluminum alloy frame 29 to rotate 90°.

[0048] When the rotary drive assembly stops working, the electromagnetic telescopic rod 22 starts the block 10 to rise, and then the block 10 is inserted into the slot 21, so as to fix the chuck 20 and then fix the aluminum alloy frame 29 to prevent the aluminum alloy frame 29 from rotating during weighing measurement.

[0049] It should be noted that the worm wheel 12 and the worm 13 have the ability of self-locking, and the cooperation between the clamping block 10 and the clamping slot 21 is used to improve the stability of the aluminum alloy frame 29 .

[0050] The fixed plate 23 is slidably connected to the movable rod of the electromagnetic telescopic rod 22 , and the fixed plate 23 is used to limit the sliding rod of the electromagnetic telescopic rod 22 , thereby further improving the stability of the aluminum alloy frame 29 .

[0051] Reference Figure 1-Figure 4 and Figure 9-10The cross-infection prevention component includes two groups of transmission rollers 30 rotatably mounted at both ends of an aluminum alloy frame 29, and a belt 40 is coupled to the two groups of transmission rollers 30 and a weighing plate 32. A third motor 31 is fixedly mounted on the side wall of the aluminum alloy frame 29, and the output shaft of the third motor 31 is fixedly connected to the transmission roller 30.

[0052] In this embodiment, the third motor 31 is started and drives the belt 40 to rotate. Under the limitation of the limiting wheel 33, the belt 40 rotates along the outer edge of the "L" shape to replace the belt 40 that has been touched by the user, and the belts 40 that have been touched by other users are cleaned and disinfected during rotation to avoid cross infection among users.

[0053] Reference Figure 1 , Figure 4 and Figure 5 A connecting block 34 is fixedly mounted on the side wall of the aluminum alloy frame 29, a third guide rail 35 is fixedly mounted on the connecting block 34, a third mounting plate 36 is slidably mounted on the third guide rail 35, a distance measuring sensor 38 is fixedly mounted on the third mounting plate 36, a rubber strip 37 is fixedly mounted on the third mounting plate 36, and the rubber strip 37 is interference connected with the third guide rail 35.

[0054] In this embodiment, the third mounting plate 36 is made to rest against the top of the user's head, the user's feet are made to contact the belt 40 that is in contact with the weighing plate 32, and then the distance between the belt 40 and the third mounting plate 36 is measured by the distance measuring sensor 38, thereby measuring the user's height, so that a corresponding treatment (recuperation) plan can be formulated in combination with the user's weight data. The design of the rubber strip 37 can prevent the third mounting plate 36 from sliding when no external force is applied, thereby making the measurement data more accurate.

[0055] In this embodiment, by switching the body scale to the lying weighing measurement mode, an accurate height measurement can be performed on a person who cannot stand upright when standing.

[0056] Reference Figure 1 , Figure 4 , Figure 12-Figure 15The disinfection assembly includes a connecting ring 18 fixedly mounted on the first connecting seat 5 and the second connecting seat 6, a mounting tube 42 is rotatably mounted on the connecting ring 18, a water spray hole 43 is provided on the mounting tube 42, a sponge cover 44 is sleeved on the mounting tube 42, the sponge cover 44 covers the water spray hole 43, the sponge cover 44 is in contact with the belt 40, and a fifth connecting seat 41 is slidably mounted on both second guide rails 4, a fourth motor 45 is fixedly mounted on one of the fifth connecting seats 41, and the output shaft of the fourth motor 45 is fixedly connected to the mounting tube 42; an alcohol tank 39, a first water pipe 51 is fixedly mounted on the alcohol tank 39; a mounting cylinder 49, fixed It is installed on another fifth connecting seat 41, and a gear speed increaser 47 is fixedly installed on the fifth connecting seat 41. The input shaft of the gear speed increaser 47 is fixedly connected to the mounting tube 42. A mounting rod 48 is rotatably installed in the mounting cylinder 49, and a turbine 50 is fixedly installed on the mounting rod 48. The mounting rod 48 is fixedly connected to the output end of the gear speed increaser 47; a sealing swivel 46 is rotatably installed on the mounting tube 42, and the sealing swivel 46 is connected to the inner cavity of the mounting tube 42. The sealing swivel 46 is fixedly connected to the discharge end of the mounting cylinder 49 through the second water pipe 52, and the output end of the first water pipe 51 is fixedly connected to the liquid inlet end of the mounting cylinder 49.

[0057] In this embodiment, the fourth motor 45 is started, and the fourth motor 45 drives the mounting tube 42 to rotate, and the mounting tube 42 drives the sponge cover 44 to rotate to scrape the belt 40. During this process, the mounting tube 42 drives the gear speed increaser 47 to rotate, and the output speed is increased by the gears inside the gear speed increaser 47. Then the gear speed increaser 47 drives the mounting rod 48 to rotate, and the mounting rod 48 drives the turbine 50 to rotate. The turbine 50 extracts the medical alcohol in the alcohol tank 39 through the first water pipe 51, and then transmits it to the sealing swivel 46 through the second water pipe 52, enters the mounting tube 42 through the sealing swivel 46, and then sprays it onto the sponge cover 44 through the water spray hole 43 to soak the sponge cover 44, and then smears it on the belt 40 through the sponge cover 44 to sterilize and disinfect the surface of the belt 40, thereby preventing cross infection.

[0058] In this embodiment, the horizontal distance between the rotation axis of the mounting tube 42 and the rotation axis of the first rotating shaft 11 is the same as the height distance between the rotation axis of the mounting tube 42 and the rotation axis of the first rotating shaft 11, and the first rotating shaft 11 is higher than the mounting tube 42. Therefore, when the device is in the standing weighing measurement mode, the sponge cover 44 is in contact with the belt 40. Then, when the device is switched to the lying weighing mode, the sponge cover 44 is still in contact with the belt 40. Therefore, no matter what mode the device is in, alcohol can still disinfect and clean the surface of the belt 40 through the sponge cover 44, thereby preventing cross infection.

[0059] Reference Figure 1 and Fig.10An electric heating plate 53 is fixedly installed on the inner side of the aluminum alloy frame 29, and the heating temperature of the electric heating plate 53 is ≤37°C.

[0060] Among them, 37°C is a temperature close to normal body temperature of the human body. Therefore, the use of such an electric heating plate 53 can provide warmth without causing overheating or discomfort to the user. Among them, the aluminum alloy frame 29 is made of heat-conductive aluminum alloy, and the belt 40 is a silicone belt. The heat generated by the electric heating plate 53 can be transmitted to the belt 40 through the aluminum alloy frame. Therefore, in this embodiment, the electric heating plate 53 heats the aluminum alloy frame 29 and transmits the heat to the belt 40, which can not only provide a comfortable temperature for a person lying down for weighing and measuring, but also promote the volatilization of alcohol on the surface of the belt 40, so that the surface of the belt 40 remains dry.
