Description

Technical Field

[0002] With the improvement of modern living standards and the enhancement of health awareness, children's height measurement has become a common health monitoring project in daily life. Children's height is one of the important indicators to measure their growth and development, and accurate height measurement is of great significance for understanding children's growth trends and timely discovering developmental problems. At present, there are many children's height measurement instruments on the market, which usually combine weighing and height measurement functions. However, most of these devices can only provide a single measurement method, and the lack of children's sitting height and posture correction function makes them have certain limitations in practical applications.

[0003] Although existing children's height measuring instruments can accurately measure children's height and weight, they generally cannot conveniently measure children's sitting height. Since most devices are designed only for children's standing postures, effective height measurement cannot be performed when children are in sitting or other special postures. In addition, most devices in the prior art lack posture feedback and correction functions. During the measurement process, children may have inaccurate measurement data due to improper standing or sitting postures. The lack of real-time posture correction and feedback will directly affect the accuracy of height measurement, especially in situations where height requirements are high, the error may be more significant.

[0038] Please refer to the attached Figure 1 - Attachment Figure 3 The embodiment of the present invention provides a child height measuring instrument, comprising:

[0039] The weighing mechanism 2 is fixedly connected to the middle upper surface of the mounting platform 1, and its function is to provide an installation position for other mechanisms and to weigh and measure the weight of the child to be measured. The weighing mechanism 2 includes a mounting box 201 and a weighing device 202. The mounting box 201 is fixedly connected to the middle upper surface of the mounting platform 1, and multiple groups of weighing devices 202 are all fixedly connected to the inside of the mounting box 201. The upper end of the weighing device 202 is fixedly connected to a mounting top plate 203.

[0040] Specifically, the installation box 201 is located in the central position of the device, fixedly connected to the middle upper surface of the installation platform 1, and is used to install multiple groups of weighing devices 202 inside, and provide activity space for installing the top plate 203. The weighing device 202 is the core component of the weighing mechanism. The weighing device 202 detects the weight of the child to be measured through the pressure sensor or load sensor set inside. The weighing device 202 is combined with the inside of the installation box 201 by a fixed connection. Each group of weighing devices can transmit data to the control mechanism 9 in real time, so that the staff can read the weight value through the operating device 902. When the child stands or sits in the measuring area of ​​the equipment, the weight is applied to the sensor on the weighing device. The sensor converts the pressure change into an electrical signal and feeds back the weight information to the control system through the data processing unit. The installation top plate 203 is a fixed support plate above the installation box 201, which is used to provide an installation position for other mechanisms.

[0041] Please refer to the attached Figure 4 , measuring mechanism 3, measuring mechanism 3 is fixedly connected to the upper rear surface of the weighing mechanism 2, and its function is to measure the height of the child to be measured by non-contact measurement, and provide an installation position for the movable mechanism 4, the measuring mechanism 3 includes a fixed base 301 and a supporting slide 302, the lower side of the fixed base 301 is fixedly connected to the upper rear surface of the installation box 201, the lower end of the supporting slide 302 is fixedly connected to the upper side of the fixed base 301, the upper side of the supporting slide 302 is fixedly connected with a height measuring device 303, and the front lower surface of the height measuring device 303 is fixedly connected with a non-contact measuring probe 304.

[0042] Specifically, the lower side of the fixed base 301 is fixedly connected to the upper surface of the rear side of the installation box 201 to ensure that the measuring mechanism 3 is firmly installed on the weighing mechanism 2 to avoid shaking or displacement during the measurement process, which affects the measurement accuracy. The support chute 302 is a support member with a C-shaped chute on the back. The lower end of the support chute 302 is fixedly connected to the upper side of the fixed base 301. Its main function is to provide support for the height measuring device 303 and provide activity space and installation position for the movable mechanism 4. The height measuring device 303 is fixedly connected to the upper side of the support chute 302. As the core component of the measuring mechanism, it is responsible for processing the signal from the non-contact measurement probe 304 and calculating the height data of the child. The height measuring device 303 has a built-in data processing unit and a communication interface, which can transmit the measurement results to the control mechanism 9 for display or storage. The non-contact measurement probe 304 is fixedly connected to the lower surface of the front side of the height measuring device 303. Its function is to measure the distance between the child's head and the probe by transmitting and receiving specific signals such as infrared, ultrasonic or laser. The non-contact measurement method avoids the inconvenience caused by direct contact and improves the comfort and safety of measurement.

[0043] Please refer to the attached Figure 5 , movable mechanism 4, movable mechanism 4 is arranged on the rear side of measuring mechanism 3, and its function is to drive the side support mechanism 5 on the rear side of movable mechanism 4 to move up and down through cooperation with measuring mechanism 3, movable mechanism 4 comprises fixed rack 401 and limit slider 402, fixed rack 401 is fixedly connected to the rear side of supporting slide groove 302, limit slider 402 is slidably connected to the inside of supporting slide groove 302, the middle part of limit slider 402 is rotatably connected with transmission shaft 404, the outer surface of transmission shaft 404 is fixedly connected with multiple groups of transmission gears 403, the outer edges of transmission gears 403 are meshed with corresponding fixed rack 401, the right side of limit slider 402 is fixedly connected with lifting drive motor 405, the power output end of lifting drive motor 405 is fixedly connected with the right end of transmission shaft 404.

[0044] Specifically, the fixed rack 401 is fixedly connected to the rear side of the supporting slide groove 302. The fixed rack 401 provides a meshing basis for the transmission gear 403, so that the limit slider 402 can move up and down smoothly. The design of the fixed rack determines the up and down travel range of the movable mechanism 4, ensuring that the movement of the limit slider 402 will not exceed the predetermined range.

[0045] The limit slider 402 is slidably connected inside the support slide 302, responsible for carrying the transmission gear 403 and providing stable sliding support, and can achieve precise up and down movement through the transmission gear 403 meshing with the fixed rack 401, thereby driving the side support mechanism 5 and the posture feedback and correction mechanism 6 to move up and down synchronously. The transmission shaft 404 is the core transmission component in the movable mechanism 4, and multiple sets of transmission gears 403 are fixedly connected to its outer surface, and the multiple sets of transmission gears 403 are all meshed with the fixed rack 401. Driven by the transmission shaft 404, they move the limit slider 402 up and down along the support slide 302 through meshing movement. The lifting drive motor 405 is fixedly connected to the right side of the limit slider 402, and the power output end of the motor is fixedly connected to the right end of the transmission shaft 404. The rotation of the motor drives the transmission shaft to rotate, thereby pushing the transmission gear 403 to mesh with the fixed rack 401, thereby causing the limit slider 402 to move up and down along the support slide 302.

[0046] Please refer to the attached Figure 6, side support mechanism 5, the side support mechanism 5 is fixedly connected to the rear side of the movable mechanism 4, and its function is to provide support for the posture feedback and correction mechanism 6, and then provide movable support for the movement of the posture feedback and correction mechanism 6, the side support mechanism 5 includes a support plate 501 and a fixed block 502, the right front side of the support plate 501 is fixedly connected to the rear side of the limiting slider 402, the rear side of the fixed block 502 is fixedly connected to the left front side of the support plate 501, the upper side of the fixed block 502 is fixedly connected with a first movable rotating shaft 503, the front side of the first movable rotating shaft 503 is fixedly connected with a first telescopic rod 504, the front end of the first telescopic rod 504 is fixedly connected with a second movable rotating shaft 505, and the upper end of the second movable rotating shaft 505 is fixedly connected with a second telescopic rod 506.

[0047] Specifically, the support plate 501 is fixedly connected to the rear side of the limit slider 402, playing a bearing and supporting role, the fixed block 502 is fixedly connected to the left front side of the support plate 501, and is used to provide an installation position for the first movable shaft 503, and the first movable shaft 503 is fixedly connected to the upper side of the fixed block 502 and connected to the first telescopic rod 504. The function of the movable shaft is to allow the first telescopic rod 504 to adjust its angle in the horizontal direction, so that the posture feedback and correction mechanism 6 can adjust its angle according to the standing or sitting posture of the child.

[0048] The first telescopic rod 504 is located at the front end of the first movable shaft 503 and can be extended and retracted within a certain range. The telescopic movement of the first telescopic rod 504 is limited by the angle adjustment of the movable shaft 503. The second movable shaft 505 is located at the front end of the first telescopic rod 504 and is connected to the second telescopic rod 506. The second movable shaft 505 allows the second telescopic rod 506 to further adjust the angle in the horizontal direction, thereby further adjusting the position of the posture feedback and correction mechanism 6 to ensure that it provides the necessary posture support for the posture feedback and correction mechanism 6 when measuring the height of the child. The cooperation between the second movable shaft 505 and the first telescopic rod 504 enables the side support mechanism to flexibly respond to the adjustment requirements of different postures.

[0049] Please refer to the attached Figure 7 , posture feedback and correction mechanism 6, the posture feedback and correction mechanism 6 is fixedly connected to the front end of the posture feedback and correction mechanism 6, its function is to attract the child's attention, collect the child's standing posture information, and make feedback to assist the child to adjust the posture, the posture feedback and correction mechanism 6 includes a movable base 601 and a feedback display 602, the right side of the movable base 601 is fixedly connected to the end of the second telescopic rod 506, the lower side of the feedback display 602 is fixedly connected to the upper side of the movable base 601, the upper side of the feedback display 602 is fixedly connected with an angle adjustment device 603, and the upper side of the angle adjustment device 603 is provided with a posture detection probe 604.

[0050] Specifically, the movable base 601 is located at the base of the posture feedback and correction mechanism 6, and is connected to the second telescopic rod 506. It mainly plays a supporting role and can adjust the display angle of the feedback display 602. The feedback display 602 is installed on the movable base 601. The function of the feedback display is to display the posture information of the child in real time and provide visual feedback to help the child understand whether he is in the correct posture. During the height measurement process, the display will attract the child's attention through graphics, text or color changes, prompting the child to adjust the standing or sitting posture to ensure the accuracy of the measurement data. The height, angle and display content of the display can be adjusted according to the specific situation of the child to ensure that the child can clearly see the feedback information and then make posture adjustments.

[0051] The angle adjustment device 603 is connected to the upper end of the feedback display 602, and is mainly used to adjust the angle of the posture detection probe 604. It can adjust the angle of the posture detection probe 604 according to the height and position of the child under the automatic operation of the control mechanism 9, so that it is always at a suitable angle for observing the child, so that the posture detection probe 604 can clearly see the posture correction information.

[0052] The function of the posture detection probe 604 is to monitor the standing posture of the child in real time in a non-contact manner. The probe usually uses image recognition technology to accurately detect the angle, position and posture deviation of the child's body. The posture detection probe 604 will continuously scan the posture data of the child and feed back this information to the control mechanism 9. If the child's posture is inappropriate, the probe will detect it and prompt the child to adjust the posture through the feedback display 602. This information is completed through real-time sensing technology, so it can accurately evaluate whether the child needs to adjust the standing or sitting posture.

[0053] Please refer to the attached Figure 8 , a measuring base mechanism 7, the measuring base mechanism 7 is fixedly connected to the middle part of the weighing mechanism 2, and its function is to provide an installation position for the child's height measurement point, and to switch the standing height measurement point and the sitting height measurement point according to specific needs. The measuring base mechanism 7 includes an electric slide rail 701 and a base switching slider 702. The lower side of the electric slide rail 701 is fixedly connected to the middle upper surface of the mounting top plate 203, the lower inner surface of the base switching slider 702 is slidably connected to the outer surface of the base switching slider 702, and the left upper surface of the base switching slider 702 is fixedly connected with a standing measuring base 703, and the lower surfaces of the front and rear sides of the standing measuring base 703 are fixedly connected with a stabilizing support block 704, and the lower side of the stabilizing support block 704 is slidably connected to the upper surface of the mounting top plate 203.

[0054] Specifically, the function of the electric slide rail 701 is to provide a horizontal sliding track for the base switching slider 702, thereby forming a stable sliding platform and driving the base switching slider 702 to move left and right. The lower inner surface of the base switching slider is slidably connected to the outer surface of the electric slide rail 701. The function of the base switching slider is to select a suitable measuring base in the standing or sitting measurement base according to the measurement requirements. The base switching slider 702 can slide along the electric slide rail 701. During the sliding process, it is kept stable by sliding connection with the electric slide rail. The left upper surface of the base switching slider is fixedly connected with the standing measurement base 703, and the right upper surface is fixedly connected with the sitting measurement base 802. When switching the measurement mode, the control mechanism 9 will drive the base switching slider 702 to move left and right through the electric slide rail 701 to select a suitable measurement base. When standing measurement is required, the base switching slider will position the standing measurement base 703 to a suitable position. If sitting measurement is required, the sitting measurement base 802 is moved to a suitable measurement position by the slider. The standing measurement base 703 is the main supporting component that provides a measurement point for the child's standing height. The standing measurement base 703 provides a stable standing platform for the child during measurement, ensuring that the child can stand upright on it for height measurement. The function of the stable support block 704 is to prevent the base from tilting or sliding during the measurement process, ensuring that the child is always in a stable position during the measurement.

[0055] Please refer to the attached Figure 8 , measuring seat mechanism 8, the measuring seat mechanism 8 is fixedly connected to the right side of the measuring base mechanism 7, and its function is to provide a measuring point for the child's sitting height, and to switch it as needed under the drive of the measuring base mechanism 7, the measuring seat mechanism 8 includes a lifting support seat 801 and a sitting posture measuring seat 802, the lower end of the lifting support seat 801 is fixedly connected to the right upper surface of the base switching slider 702, the lower side of the sitting posture measuring seat 802 is fixedly connected to the upper end of the lifting support seat 801, the rear side of the sitting posture measuring seat 802 is fixedly connected with a sitting posture limiting device 803, and the middle part of the sitting posture limiting device 803 is fixedly connected with a neck pillow 804.

[0056] Specifically, the measuring seat mechanism 8 is an important component used for sitting posture measurement in the child height measuring instrument. It realizes accurate measurement of the height of the child in a sitting position through the cooperation of the lifting support seat 801 and the sitting posture measurement seat 802. The lifting support seat 801 provides a height adjustment function for the sitting posture measurement seat 802, and enables it to move with the sliding of the base switching slider 702. The lifting support seat 801 can be lifted and lowered to ensure that the child's sitting posture measurement height meets the requirements of height measurement and ensure the accuracy of the measurement results. Precise control during the lifting process is completed by the control mechanism 9.

[0057] The sitting posture measurement seat 802 provides a stable sitting posture measurement platform for children. The sitting posture measurement seat 802 is fixedly connected to the lifting support seat 801, and a sitting posture limiting device 803 is also fixedly connected to the rear side thereof, which is used to ensure that the child can maintain a stable sitting posture during measurement. When the base switching slider 702 adjusts the sitting posture measurement seat 802 to an appropriate position, the sitting posture measurement seat 802 will move together with the lifting support seat 801 and adjust the height as needed so that the child can measure his height in a suitable sitting posture. The sitting posture limiting device 803 is a component used in conjunction with the sitting posture measurement seat 802. Its function is to ensure that the child can maintain the correct position and stability during the sitting posture measurement process. The sitting posture limiting device 803 effectively limits the sitting posture range of the child by means of physical restriction or slight restraint, and prevents inaccurate measurement data due to inappropriate sitting posture. The neck pillow 804 is a part of the sitting posture limiting device 803, which is fixed in the middle of the sitting posture limiting device to provide additional neck support for the child. This design can help children maintain the correct head position, thereby avoiding deviations in measurement results due to improper head position when measuring in a sitting position.

[0058] Please refer to the attached Fig. 9 , control mechanism 9, the control mechanism 9 is fixedly connected to the right side of the installation platform 1, and its function is to facilitate the staff to control the device, and then control the equipment to perform the child height measurement operation. The control mechanism 9 includes a console base 901 and an operating device 902. The lower side of the console base 901 is fixedly connected to the upper right side surface of the installation platform 1, and the lower side of the operating device 902 is fixedly connected to the upper side of the console base 901. The left upper surface of the operating device 902 is fixedly connected with a display panel 903, and the right upper surface of the operating device 902 is fixedly connected with an operating panel 904. The operating device 902 is electrically connected to the weighing device 202, the height measuring device 303, the non-contact measuring probe 304, the lifting drive motor 405, the feedback display 602, the angle adjustment device 603, the posture detection probe 604, the electric slide rail 701, the display panel 903, and the operating panel 904.

[0059] Specifically, the console base 901 is the physical support part of the entire control mechanism, providing a stable installation platform for the operating device 902, and providing space for the layout of the entire control mechanism 9. The operating device 902 is the main control interface of the children's height measuring instrument. The staff operates and sets the equipment through it. The operating device 902 integrates the control and display functions of the equipment. The staff sets the operation mode and selects the measurement method through the buttons on the operating panel 904. The display panel 903 is used to display the measurement results, equipment status and other related information in real time. It can feedback weighing data, height measurement data, posture feedback information, etc. in real time to help the staff understand the current working status of the equipment. The operating panel 904 is used for user input and operation. The staff inputs instructions through the operating panel 904 to control the working status of each component, such as starting weighing, height measurement, switching measurement mode, etc. The control mechanism 9 establishes a connection with each important component in the device through electrical connection. Through these electrical connections, the operating device 902 can issue instructions to each component to control their work, thereby completing the entire measurement process.

[0060] Working principle: First, the user guides the child to be measured to the measuring area of ​​the device. During this process, the weighing mechanism 2 of the device will first measure the weight. When the child stands or sits in the weighing area, the pressure sensor in the weighing device 202 detects the pressure change of the child's weight and transmits the data to the control mechanism 9 through a signal. The control mechanism 9 displays the weight data in real time through the operating device 902, and the staff can confirm the child's weight based on the displayed information.

[0061] Next, the device automatically enters the height measurement mode. Depending on the child's standing or sitting posture, the device will switch to different measuring bases. When standing measurement is required, the base switching slider 702 slides the standing measurement base 703 into a suitable position through the action of the electric slide rail 701. When the child stands on the base, the non-contact measurement probe 304 in the measuring mechanism 3 starts working. The probe emits a specific signal and calculates the child's height by measuring the reflected signal. The data is transmitted to the control mechanism 9 in real time and displayed on the display panel 903 of the operating device 902.

[0062] If sitting posture measurement is required, the base switching slider 702 will adjust the sitting posture measurement seat 802 to an appropriate position. At this time, the lifting support seat 801 will ensure that the sitting posture measurement seat 802 reaches an appropriate height, and the child sits on the seat, and the measuring mechanism 3 continues to measure the height in a non-contact manner. The sitting posture limit device 803 ensures that the child maintains a stable sitting posture during measurement and prevents the measurement data from being affected by improper sitting posture.

[0063] During the height measurement process, the posture feedback and correction mechanism 6 of the device monitors the child's standing or sitting posture in real time through the posture detection probe 604. When the probe detects that the child's posture is incorrect, the feedback display 602 prompts the child to adjust it through visual or text. The angle of the feedback display is automatically adjusted by the angle adjustment device 603 to ensure that it is always at an angle suitable for observing the child's posture.

[0064] During the measurement process, the movable mechanism 4 cooperates with the side support mechanism 5 to control the lifting position of the measuring mechanism by driving the lifting motor 405 to ensure that the child maintains a proper posture during the measurement. The movable mechanism 4 achieves precise vertical movement through the meshing of the gear and the rack, so that the measuring mechanism can adjust the measuring distance in real time according to the height of the child.

[0065] The control mechanism 9 is the core of the entire system and is responsible for coordinating the operation of each component. The staff inputs instructions through the operation panel 904 to control the equipment to complete tasks such as weight measurement, height measurement, and posture correction. The control system can intelligently adjust the working state of the equipment according to the measurement mode switching, sensor data feedback, and posture correction requirements. Finally, the equipment ensures the accuracy of each measurement result through precise posture detection, weight measurement, and height measurement. The measurement data is displayed and saved by the control mechanism, and the staff can query and record the height changes of the child at any time to assist in the health management of the child.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
