[0002] With the deepening of health management concepts in my country, the country has proposed a "Three-Year Weight Management" action plan, aiming to improve the overall health of the population through scientific and reasonable weight monitoring and management. As an important device for height and weight monitoring, intelligent height and weight scales are widely used in hospitals, communities, schools, gyms, and other public health management venues.

[0003] However, with increased usage frequency and more complex environments, the equipment is prone to tilting or even falling when subjected to external impacts or when placed unstable, which may damage the equipment or even injure surrounding people or objects, posing a significant safety hazard.

[0004] In addition, height measurement requires the equipment to be tall enough, but existing height and weight scales usually adopt a fixed structure. Therefore, they require a large packaging volume and placement space during transportation. The large packaging volume also increases the difficulty of manual handling. Utility Model Content

Detailed Implementation

[0030] To illustrate the technical features, objectives, and effects of this utility model in detail, the following description, in conjunction with the accompanying drawings and embodiments, provides a further detailed explanation. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0031] Please see the appendix Figure 1-8 A utility model embodiment provides an intelligent height and weight scale, comprising: a weighing module 100 for acquiring human body weight data, a support member located below the weighing module 100, the support member being arranged asymmetrically front and back; a lower support module 500 installed at the rear end of the weighing module 100, having a forward-tilting degree of freedom, the upper end of the lower support module 500 being a hollow structure; an upper support module 200 installed inside the lower support module 500 and having a vertical movement degree of freedom along the lower support module 500; a height measurement module 300 for acquiring human body height data, the height measurement module 300 being installed on the upper support module 200 and parallel to the weighing module 100, the height measurement module 300 having a downward-tilting degree of freedom; and a control module 400 connected to the weighing module 100 and the height measurement module 300, for receiving and outputting height and weight measurement results.

[0032] In the above embodiments, the weighing module 100 and the height measurement module 300 acquire the weight and height data of the human body and send them to the control module 400 for output. The asymmetrically arranged support components prevent tilting when the user steps on the edge of the weighing pan, improving stability. At the same time, the equipment can quickly return to a balanced state when it is placed unstable or subjected to external impact, avoiding damage to the equipment or injury to personnel. During transportation or storage, the lower support module 500 and the height measurement module 300 can be flipped and folded, and the upper support module 200 can be retracted downwards to reduce the packaging volume, thereby facilitating transportation or handling.

[0033] Based on the above embodiments, the weighing module 100 and the lower support module 500 are detachably connected. The weighing module 100 and the lower support module 500 are also connected by a first hinge 122, so that the weighing module 100 and the lower support module 500 are in a fixed state during operation. When transportation or handling is required, the detachable connection can be disassembled so that the lower support module 500 can be flipped and folded forward. The height measuring module 300 and the upper support module 200 are detachably connected. The height measuring module 300 and the upper support module 200 are also connected by a second hinge 230, so that the height measuring module 300 and the upper support module 200 are in a fixed state during operation. When transportation or handling is required, the detachable connection can be disassembled so that the height measuring module 300 can be flipped and folded downward, thereby reducing the packaging volume.

[0034] Based on the above embodiments, the weighing module 100 includes a weighing pan base 110, a support member installed below the weighing pan base 110, a weighing pan base housing 120 and a weighing sensor 130 installed on the weighing pan base 110, the weighing sensor 130 extending through the weighing pan base housing 120, a weighing pan 140 installed above the weighing sensor 130, and the support member being foot pads 160, which include two front foot pads 161 and two rear foot pads 162. The distance between the rear foot pads 162 is greater than the distance between the front foot pads 161, thereby making the foot pads 160 asymmetrically distributed front and back.

[0035] Based on the above embodiments, the weighing pan base 110 includes a base plate 112. A front support square tube 111 and a rear support square tube 118, as well as two left and right support square tubes 114 located between the front and rear support square tubes 111 and 118, are installed on the top of the base plate 112. The front support square tube 111, rear support square tube 118, and left and right support square tubes 114 are all installed close to the edge of the base plate 112 to further reduce the risk of equipment tipping. A connecting fixing plate 116 is installed on the left and right support square tubes 114. The upper end of the connecting fixing plate 116 penetrates the weighing pan base housing 120 and is connected to the lower support module 500. A [missing information - likely a component or material] is installed on the side of the left and right support square tubes 114 closest to the edge of the base plate 112. Small square tube 117 is located between the rear support square tube 118 and the connecting fixing plate 116. A sensor fixing plate 115 is installed on the base plate 112. The weighing sensor 130 is installed on the sensor fixing plate 115. One end of the sensor fixing plate 115 abuts against the connecting fixing plate 116. The other end of the sensor fixing plate 115 is symmetrically equipped with reinforcing ribs 113 between the front support square tube 111 and the front support square tube 111. The front support square tube 111, the rear support square tube 118, the left and right support square tubes 114 and the small square tube 117 are made of galvanized steel pipe square tubes. The base plate 112 and the connecting fixing plate 116 are made of stainless steel plates, thereby increasing the weight of the weighing pan base 110.

[0036] The front support square tube 111, rear support square tube 118, left and right support square tubes 114, small square tube 117, connecting fixing plate 116, and reinforcing rib 113 are all fixed by welding. The base plate 112 is connected to the front support square tube 111, rear support square tube 118, and left and right support square tubes 114 by spot welding. The connecting fixing plate 116 is used to connect the left and right support square tubes 114 to increase their strength. The sensor fixing plate 115 is connected to the left and right support square tubes 114 and the connecting fixing plate 116, and the reinforcing rib 113 is connected to the left and right support square tubes 114 and the sensor fixing plate 115 by welding. This can strengthen the strength of this part and prevent local deformation of the base plate 112.

[0037] To facilitate temporary or short-distance relocation of the equipment, rear wheels 150 can be installed at the rear end of the base plate 112. In this case, the operator can tilt the equipment backward so that the rear wheels 150 contact the ground and use the rolling of the rear wheels 150 to transfer the equipment.

[0038] To further reduce the height of the weighing module 100, the front support square tube 111, the rear support square tube 118, the left and right support square tubes 114 and the small square tube 117 can be made of flat galvanized steel square tubes to reduce the height of the weighing pan base 110. At the same time, a recessed support mounting position 121 is set at the rear end of the weighing pan base shell 120, and the first hinge 122 is installed in the support mounting position 121.

[0039] Based on the above embodiments, the lower support module 500 includes a lower profile 530, which is a hollow structure. A plastic rack 540 is installed inside the lower profile 530 along its height direction. A gear baffle 560 is installed on the top of the plastic rack 540. The upper support module 200 includes an upper profile 210, which is a hollow structure. An upper profile inner bracket 240 is installed at the lower end of the upper profile 210. A gear mounting plate 242 is provided below the upper profile inner bracket 240. A one-way damping gear 270 is installed on the gear mounting plate 242. The one-way damping gear 270 meshes with the plastic rack 540. The lower profile 530 and the upper profile 210 are made of aluminum profiles to reduce the weight of the upper support module 200 and the lower support module 500. The transmission method employing a one-way damping gear 270 meshing with a plastic rack 540 ensures that the upper support module 200 experiences no damping when extended upwards, but requires overcoming resistance when retracting downwards. This prevents the upper support module 200 from slipping off due to gravity after being extended, thus affecting its use. A gear baffle 560 is used to limit the one-way damping gear 270, preventing the upper support module 200 from detaching from the lower support module 500.

[0040] Based on the above embodiments, a bearing fixing component 250 is installed below the inner support 240 of the upper profile, and a rubber-coated bearing 260 is installed on the bearing fixing component 250. The outer circumference of the rubber-coated bearing 260 abuts against the inner wall of the lower profile 530. A friction plate 280 is installed on the outer side of the upper profile 210, and the side of the friction plate 280 abuts against the inner wall of the lower profile 530 on the other side. During extension and retraction, the rolling friction between the rubber-coated bearing 260 and the inner wall of the lower profile 530 and the sliding friction between the friction plate 280 and the inner wall of the lower profile 530 increase the friction force for the up and down movement of the upper profile 210, making its extension and retraction smooth, while reducing the shaking of the upper profile 210 during the extension and retraction process, making the extension and retraction process more stable.

[0041] Based on the above embodiments, the lower support module 500 includes a support base 510, a support base housing 520 is installed on the upper part of the support base 510, and a metal frame 511 is provided on the support base 510. The metal frame 511 penetrates the support base housing 520 and extends upward. The metal frame 511 is used to install and position the lower profile 530. The lower profile 530 is installed on the metal frame 511 to ensure accurate positioning and stable installation. The support base 510 is installed in the support base mounting position 121 and is detachably connected. The front end of the support base 510 is connected to the first hinge 122. Hand screws 550 are installed on both sides of the lower profile 530. When the hand screws 550 are rotated inward, they can abut against the outer surface of the upper profile 210. In use, after the upper support module 200 is extended and retracted into place, the upper support module 200 can be further locked by tightening the hand screws 550 so that their interior abuts against the outer surface of the upper profile 210. To make the upper cut of the lower profile 530 aesthetically pleasing and to avoid cutting the operator, a profile sleeve 570 can be installed on the top of the lower profile 530.

[0042] Based on the above embodiments, the height measurement module 300 includes a housing composed of a lower shell 310 and an upper shell 340. A length sensor fixing bracket 330 is installed inside the housing, and an ultrasonic length sensor 350 is installed on the length sensor fixing bracket 330.

The upper shell 340 is connected to the outer shell fixing bracket 320, and the upper shell 340 and the outer shell fixing bracket 320 are detachably connected. For example, the upper shell 340 is locked to the outer shell fixing bracket 320 from the outside by screws. The second hinge fixing plate 220 is connected to the lower shell 310 by a second hinge 230, so that after the connection between the upper shell 340 and the outer shell fixing bracket 320 is detached, the height measurement module 300 can be flipped downward.

[0043] Based on the above embodiments, the control module 400 includes a motherboard 410, on which a height and weight board 420, a WIFI board 460, a speaker 470, and a touch screen 480 are connected.
