Description

Technical Field

[0001] This utility model relates to the field of body posture detection technology, specifically, to a body posture detection device based on infrared ranging. Background Technology

[0002] The human body's posture is mainly formed by the support of bones and the interaction of muscles. However, the human skeleton, especially the skeleton of adolescents, is easily changed by daily habits or some pathological problems, such as uneven shoulders, hunchback, and leg length discrepancy. When these changes have occurred thoroughly, they can be detected by visual observation. However, when these changes have just appeared, they are more difficult to detect by visual observation.

[0003] Therefore, regular physical examinations are an essential part of the process.

[0004] Currently, there are many instruments for body posture detection, but they are all multifunctional and expensive, so they can only be used in environments with large-scale traffic, such as hospitals. For smaller areas such as schools and communities, the main constraint on using these devices is cost.

[0005] Some specialized instruments and equipment are relatively simplified in design, but these devices are highly targeted, such as detection devices mainly for scoliosis or detection devices mainly for leg length discrepancy. Although these specialized devices are low in cost, they are not versatile enough and have limited functions in schools, communities, and other tasks that are mainly used for screening.

[0006] Therefore, in order to meet the needs of preliminary screening for abnormalities in the overall body posture of people in schools, communities, and other places, it is necessary to design a simple, low-cost, and highly versatile body posture detection device.

[0007] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing a simple, low-cost, and highly versatile infrared ranging-based body posture detection device.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is: a body posture detection device based on infrared ranging, comprising a base, a column and a top structure forming an inverted frame;

[0010] The base is provided with a platform for standing;

[0011] The column is provided with at least one horizontal beam that can slide up and down, and at least two first infrared ranging sensors that can slide horizontally along the horizontal beam are provided on the front side of the horizontal beam.

[0012] At least two second infrared ranging sensors that can slide horizontally along the top frame are provided at the lower end of the top frame; the sliding direction of the second infrared ranging sensors is the same as the sliding direction of the first infrared ranging sensors.

[0013] The front side of the crossbeam and the lower end of the top frame are respectively provided with scales along the length direction;

[0014] Each of the first infrared ranging sensors and each of the second infrared ranging sensors are connected to the central processing unit to output the collected ranging information.

[0015] Based on the above, the front side of the column is provided with a vertical sliding groove, and the crossbeam is provided with a crossbeam slider corresponding to the vertical sliding groove at the center position of the crossbeam. The friction between the vertical sliding groove and the crossbeam slider is greater than the overall weight of the crossbeam, so that the crossbeam can be suspended at any position of the vertical sliding groove.

[0016] Based on the above, the front end face of the crossbeam is provided with a first horizontal groove, the front end face of the crossbeam is a vertical plane, the back of the first infrared ranging sensor is a vertical surface that is in close contact with the front end face of the crossbeam, the rear end of the first infrared ranging sensor slides in cooperation with the first horizontal groove through a sensor slider, the rear end of the first infrared ranging sensor is magnetically attached to the front end face of the crossbeam, the scale is set on the front end face of the crossbeam, and a reading pointer is set on the first infrared ranging sensor corresponding to the scale.

[0017] Based on the above, the bottom end of the top frame is provided with a second horizontal sliding groove, the bottom end surface of the top frame is a plane, the back of the second infrared ranging sensor is a plane that is in close contact with the bottom end of the top frame, the rear end of the second infrared ranging sensor slides in cooperation with the second horizontal sliding groove through a sensor slider, the rear end of the second infrared ranging sensor is magnetically attached to the bottom end of the top frame, the scale is set on the bottom end plane of the top frame, and a reading pointer is set on the second infrared ranging sensor corresponding to the scale.

[0018] Based on the above, the first and second horizontal slides are provided with drag chains for connecting the various infrared ranging sensors.

[0019] Based on the above, a thin-film pressure distribution sensor is configured on the platform, and the thin-film pressure distribution sensor is connected to the central processing unit.

[0020] Based on the above, the platform is provided with a protrusion for positioning, and the two sides of the protrusion serve as positioning reference surfaces for the inner sides of the feet when standing with both feet.

[0021] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:

[0022] The base platform allows a person to stand, facing or with their back to the pillar. A first infrared ranging sensor on the crossbeam detects the left-right deviation of the body; a second infrared ranging sensor on the top frame detects the left-right height difference. Combined, these sensors can screen for issues caused by skeletal development problems such as spinal deformities, uneven shoulders, and leg length discrepancies. This device is not used for specific disease diagnosis, but only for preliminary screening of abnormal body postures. It informs the recipient of any abnormal posture and allows them to proceed to a professional institution for further testing and diagnosis. This improves the efficiency of posture screening, reduces the pressure on hospitals and other medical resources, and is inexpensive, making it suitable for widespread application in communities, hospitals, and remote areas.

[0023] Furthermore, while infrared ranging sensors have a lower overall cost and lower accuracy compared to laser ranging sensors, their cost is extremely low. They are accurate enough for initial screening and are conducive to widespread application.

[0024] Furthermore, by combining magnetic attraction and sliding groove methods, the installation accuracy of the sensor is ensured to be high enough, providing sufficient precision even in simplified equipment. Attached Figure Description

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0030] like Figure 1 and Figure 2As shown, a body posture detection device based on infrared ranging includes a U-shaped frame consisting of a base 1, a column 2, and a top frame 3. Typically, the column 2 corresponds to the back or face of the human body. The base 1 is provided with a platform for standing. In this embodiment, a thin-film pressure distribution sensor 4 is arranged on the platform to detect the pressure distribution of the human body based on the feet and determine the basic state of the human body.

[0031] In this embodiment, as Figure 3 As shown, the platform is provided with a protrusion 8 for positioning, and the two sides of the protrusion 8 serve as positioning reference surfaces 9 for the inner sides of the feet when standing with both feet.

[0032] The column 2 is provided with at least one horizontal beam 5 that can slide up and down. At least two first infrared ranging sensors 6 that can slide horizontally along the horizontal beam 5 are provided on the front side of the horizontal beam 5. The front side of the horizontal beam 5 and the lower end of the top frame 3 are respectively provided with scales arranged along the length direction.

[0033] Specifically, in this embodiment, the front side of the column 2 is provided with a vertical slide groove 21, and the crossbeam 5 is provided with a crossbeam slider corresponding to the vertical slide groove 21 at the center position. The friction between the vertical slide groove and the crossbeam slider is greater than the overall weight of the crossbeam, so that the crossbeam can be suspended at any position of the vertical slide groove.

[0034] The front end face of the crossbeam 5 is provided with a first horizontal groove 51. The front end face of the crossbeam 5 is a vertical plane. The back side of the first infrared ranging sensor 6 is a vertical plane that is in close contact with the front end face of the crossbeam. The rear end of the first infrared ranging sensor slides in cooperation with the first horizontal groove through a sensor slider 61. The rear end of the first infrared ranging sensor 6 is magnetically attached to the front end face of the crossbeam. The scale is set on the front end face of the crossbeam. The first infrared ranging sensor is provided with a reading pointer corresponding to the scale.

[0035] At least two second infrared ranging sensors 7, which can slide horizontally along the top frame 3, are provided at the lower end of the top frame 3. The sliding direction of the second infrared ranging sensors 7 is the same as that of the first infrared ranging sensor 6. A second horizontal sliding groove 31 is provided at the bottom end of the top frame 3. The bottom end surface of the top frame 3 is a plane. The back of the second infrared ranging sensor 7 is a plane that is in close contact with the bottom end of the top frame 3. The rear end of the second infrared ranging sensor 7 is slidably engaged with the second horizontal sliding groove 31 through a sensor slider. The rear end of the second infrared ranging sensor 7 is engaged with the bottom end of the top frame 3 through magnetic attraction. The scale is set on the bottom end plane of the top frame, and a reading pointer is set on the second infrared ranging sensor 7 corresponding to the scale.

[0036] Each of the first infrared ranging sensors and each of the second infrared ranging sensors are connected to the central processing unit to output the collected ranging information.

[0037] To overcome the line stability problem caused by the frequent movement of infrared ranging sensors, drag chains for connecting each infrared ranging sensor are provided in the first and second horizontal slides.

[0038] Working principle explanation:

[0039] The person stands on the platform of base 1, adjusts their posture, keeps their back facing the column, and tells the test subject to stand naturally and relax, so that the body is in a natural upright position, and the test begins.

[0040] First, adjust the height of the crossbeam 5 to the area below the shoulders and back of the human body. Then, adjust the two first infrared ranging sensors 6 to symmetrical positions on both sides of the human body. The symmetrical positions can be determined according to the scale. Then, read the values ​​of the first infrared ranging sensors 6 and record the scale for correlation. In this way, adjust the measurement points, read multiple sets of readings of the first infrared ranging sensors 6, and record the scale for correlation. This will give you a set of data about the human back. By comparing the data, you can determine whether there is a problem of forward or backward tilting of the back.

[0041] If multiple infrared ranging sensors are set up, the process can be simplified by determining the positions of multiple infrared ranging sensors to read multiple data at once.

[0042] Of course, you can also adjust the height of beam 5 and record multiple sets of data for comparison.

[0043] If a significant difference is observed, the examination can be stopped, indicating a postural problem. It is recommended to seek further testing at a hospital or other professional institution.

[0044] Once the back problem has been detected, the height distribution on the left and right sides will be checked.

[0045] Specifically, the two infrared ranging sensors 7 at the lower end of the top frame 3 are adjusted to be above the shoulders of the human body. After recording the scale, the height values ​​of the shoulders are read. According to the aforementioned method, a set of data is obtained through adjustment, and then compared to determine whether there are superficial problems such as uneven shoulders, leg length discrepancy, or height differences caused by spinal torsion.

[0046] If significantly different data are found, the examination should be stopped. If this indicates a postural problem, it is recommended to go to a hospital or other professional institution for further testing.

[0047] The thin-film pressure distribution sensor 4 on the sole of the foot can help the human body correct its standing posture. On the other hand, it can be used as one of the parameters to judge whether there is a problem with the body's posture on both sides. In other words, when the pressure distribution of both feet is the same, but there is obvious incoordination in the appearance of the body, it can be basically judged that there is a problem with the body posture.

[0048] The above-mentioned equipment has a simple structure, inexpensive components, and is easy to use. It does not require complex algorithms and is easy to develop, making the overall product cost low and easy to promote and apply in communities, schools, remote areas and other places.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
