The backrest design should be ergonomic, support the child's back and protect the spine. The chair can effectively protect the health of students' spine, but this needs to be based on the correct use of the chair. Scoliosis is a common spinal deformity disease, also known as scoliosis. The main manifestation is that the side of the spine deviates to one side, making the back present a C-shaped or S-shaped curve. A spinal X-ray shows that the spine has a lateral curvature greater than 10°, which can be diagnosed as scoliosis.

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict. Example

[0021] The student spine health monitoring and testing chair is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-6As shown, a student spine health monitoring and testing chair provided by the present invention includes a testing cushion 7 and a testing backrest 1. The testing backrest 1 is fixed to the rear side of the testing cushion 7, and a supporting leg is arranged below the testing cushion 7; a pressure testing cushion 8 is arranged on the testing cushion 7, and a plurality of sitting pressure sensors 9 are arranged in the pressure testing cushion 8; the sitting pressure sensor 9 adopts a general pressure sensor, and the sitting pressure sensor 9 is evenly distributed in the pressure testing cushion 8. The pressure testing cushion 8 adopts materials such as foam rubber, has good elasticity, and is more comfortable to sit on. At the same time, the pressure testing cushion 8 has a deformation space, so that the sitting pressure sensor 9 can be better triggered, and the detection is more accurate. The data of the sitting pressure sensor 9 after detection is uploaded to the cloud background system through a wireless network or Bluetooth, and the cloud generates a pressure distribution map of the entire cushion, so that it can be judged whether the sitting posture is accurate. The detection backrest 1 is provided with a plurality of spinal push plates 3 on both sides of the spine along the width direction, and the spinal push plates 3 are slidably connected with the detection backrest 1, so that the spinal push plates 3 move to the two outer sides of the spine; the detection backrest 1 is provided with a compression spring 5 to resist the spinal push plates 3, so that the spinal push plates 3 have a movement trend from both sides to the middle spine; the end of the compression spring 5 is provided with a lateral pressure sensor 6 to detect the lateral thrust of the spinal push plate 3. The compression spring 5 is in a compressed state after installation, giving the spinal push plate 3 an initial pressure. When the human body leans on the spinal push plate 3, the human body will apply an outward lateral thrust to the spinal push plate 3. When the posture is wrong, the force applied to the spinal push plate 3 at this position increases when the spine is laterally bent. At the same time, the compression of the compression spring 5 is increased, so that the compression spring 5 provides a greater reverse thrust force to help correct the straightening of the spine. The lateral pressure sensor 6 can detect the force of each position on the spinal push plate 3, so as to judge the situation of scoliosis at each position, and correct the scoliosis situation more targetedly. Three-dimensional detection of the longitudinal and lateral pressure distribution of the spine can help you better understand the spinal deformation and promptly restrict and correct the spine according to the problem.

[0023] The specific technical scheme of sliding is that a plurality of arc-shaped conduits 2 are arranged on the detection backrest 1, an arc-shaped guide post 311 adapted to the arc-shaped conduit 2 is arranged on the spinal push plate 3, the arc-shaped guide post 311 is slidably connected with the arc-shaped conduit 2, the compression spring 5 is located in the arc-shaped conduit 2, one end of the compression spring 5 is against the arc-shaped guide post 311, and a force is given to the arc-shaped guide post 311 to move toward the spine. In this embodiment, an arc-shaped conduit 2 with a little curvature is preferably used, and those skilled in the art can also directly use a straight tube without curvature. The horizontal resistance of the arc-shaped conduit 2 with curvature will increase, and a tangential component of the lateral thrust can drive the arc-shaped guide post 311 to slide in the arc-shaped conduit 2. It makes it more difficult to push the spinal push plate 3 sideways when scoliosis occurs, thereby providing greater resistance to limit scoliosis. At the same time, since the compression spring 5 is built into the arc-shaped conduit 2, its elastic force directly acts on the arc-shaped guide column 311 along the axis of the arc-shaped conduit 2, which can provide a greater elastic force, and the force will not be reduced due to the curvature of the arc-shaped conduit 2. Therefore, the force generated by the spine push plate 3 on the spine is reduced, while the force of the compression spring 5 does not change, so that the spine push plate 3 has a stronger force to limit scoliosis.

[0024] Furthermore, an arc-shaped contact plate 314 is provided on the side of the spinal push plate 3 that contacts the human body, a connecting plate 313 is provided between the arc-shaped contact plate 314 and the arc-shaped guide column 311, a guide groove 21 is provided on the arc-shaped guide tube 2, and the connecting plate 313 is slidably connected to the guide groove 21. In order to better limit the spine, a sticky soft silicone layer is provided on the outer side of the arc-shaped contact plate 314, and the sticky soft silicone layer is adsorbed on the back of the human body when in use. The sticky soft silicone layer can be made of silicone, and the sticky soft silicone layer is a thinner layer. When the back is against the arc-shaped contact plate 314, slight adsorption can be achieved, so that the back and the arc-shaped contact plate 314 will not slide relative to each other when the spine is scoliotic, thereby ensuring that the arc-shaped contact plate 314 always provides a corrective force to the spine. The lower end of the arc contact plate 314 is provided with a rotating shaft 315, and the rotating shaft 315 is rotatably connected with the connecting plate 313. A torsion spring 316 is provided between the connecting plate 313 and the arc contact plate 314, so that the end of the arc contact plate 314 has a tendency to move closer to the back of the human body. The other end of the arc contact plate 314 is provided with a limiting block, and the limiting block abuts against the connecting plate 313. The arc contact plate 314 is arranged in a rotatable form, so that the arc contact plate 314 can be well limited when the human body approaches the seat back. When the human body leans back, the compression torsion spring 316 is deformed so that the arc contact plate 314 is tightly abutted against the human body, and when the human body moves away, the torsion spring 316 is reset, so that the arc contact plate 314 moves with the human body until it is reset to the point where the limiting block abuts against the connecting plate 313 and stops.

[0025] In order to correct the spine and sitting posture in a targeted manner, a preferred technical solution is that an adjustment knob 4 is provided at one end of the arc-shaped catheter 2 away from the spine, the adjustment knob 4 is threadedly connected to the end of the arc-shaped catheter 2, the end of the adjustment knob 4 is against the compression spring 5, and the lateral pressure sensor 6 is fixed between the compression spring 5 and the adjustment knob 4. The adjustment knob 4 can adjust the compression degree of the compression spring 5, thereby providing different resistances at different positions. For scoliosis at different positions, the pressure can be adjusted in a targeted manner.

[0026] A preferred technical solution is that one spinal push plate 3 is provided in each of the guide grooves 21 at the upper and lower ends, and two spinal push plates 3 are provided in each of the guide grooves 21 in the middle position; the two spinal push plates 3 in the middle are close to the spine direction as the first spinal push plate 31, and the one away from the spine is the second spinal push plate 32, the arc guide column 311 of the first spinal push plate 31 is provided with an extension section 312 with a smaller diameter, and the arc guide column 311 of the second spinal push plate 32 is sleeved on the extension section 312 and is slidably connected with the extension section 312. Further, two compression springs 5 ​​are provided in the arc guide tube 2, the compression spring 5 with a larger diameter is sleeved on the compression spring 5 with a smaller diameter, the compression spring 5 with a larger diameter abuts against the arc guide column 311 of the second spinal push plate 32, and the compression spring 5 with a smaller diameter abuts against the extension section 312 of the first spinal push plate 31. The two spinal push plates 3 are sleeved with each other, and when the first spinal push plate 31 moves, the second spinal push plate 32 is pushed to move synchronously, and the second spinal push plate 32 can move independently, so that it can adapt to the different back widths of different people. Further, two compression springs 5 ​​are arranged in the arc-shaped conduit 2, and the compression spring 5 with a large diameter is sleeved on the compression spring 5 with a small diameter, and the compression spring 5 with a large diameter is against the arc-shaped guide column 311 of the second spinal push plate 32, and the compression spring 5 with a small diameter is against the extension section 312 of the first spinal push plate 31. The elastic force of the compression spring 5 with a small diameter is slightly smaller, so that the first spinal push plate 31 is easier to be pushed, and the distance between the two first spinal push plates 31 can be conveniently adjusted.

[0027] Preferably, the detection cushion 7 is provided with a sunken receiving groove 72 in the buttocks area, a raised portion 71 is provided in the middle position of the front side of the detection cushion 7, the middle of the rear side of the detection cushion 7 is sunken downward, and gradually rises in both directions; the raised portion 71 gradually lowers in the direction of the receiving groove 72, the receiving groove 72 extends to the raised portion 71, the receiving groove 72 is arranged along the curved surface of the raised portion 71, and the depth of the receiving groove 72 is the same at all places. The detection cushion 7 is better adapted to the human body, and the receiving groove 72 is arranged along the upper curved surface of the detection cushion 7 to maintain the curvature of the curved surface of the detection cushion 7, so that the receiving groove 72 can be more comfortable after the cushion is installed. The receiving groove 72 maintains the curvature at all places, and the depth is kept consistent at all places, so that it can be ensured that the pressure at all places is relatively uniform when sitting on it, and the detection element can be detected more accurately after installation. The structural design of the raised portion 71 makes the center of the human body tilt toward the position of the receiving groove 72, and the pressure detection is more accurate.

[0028] The preferred technical solution is that a receiving cavity 73 is provided under the detection cushion 7, and a battery 101 and a signal transceiver 102 are provided in the receiving cavity 73. The signal transceiver 102 is electrically connected to the seat pressure sensor 9 and the lateral pressure sensor 6. The battery 101 supplies power to the signal transceiver 102, and the signal transceiver 102 is connected to the background system through a wireless signal. The battery 101 ensures that the chair does not need to be plugged in and only needs to be charged regularly. The only electronic component is the signal transceiver 102, and the low power allows the battery to be used for a long time. Data processing is all performed in the background system. The data collected by the seat pressure sensor 9 is processed into a pressure distribution map of the buttocks to evaluate the stress condition of the spine, while the lateral pressure sensor 6 is processed into a pressure distribution map on both sides of the spine in the vertical direction to determine whether the pressure at various parts of the spine is uniform. Example

[0029] This embodiment also provides a detection and control method for a student spine health monitoring and detection chair, comprising the following steps: Step S01, the seat pressure sensor 9 of the pressure detection cushion 8 detects the pressure distribution of the human body on the seat, and transmits the data to the background system; Step S02, the side pressure sensor 6 of the backrest 1 detects the lateral pressure distribution of the human body, and transmits the data to the background system; the background system processes and analyzes the two data and can display them in a graphical form.

[0030] Step S03, the background system determines whether the sitting posture is correct based on the pressure distribution of the sitting pressure sensor 9. When the sitting posture is correct, the scoliosis is determined based on the pressure distribution of the lateral pressure sensor 6. When the sitting posture is correct, the pressure distribution of the spine should be relatively uniform in theory. When the pressure of the lateral pressure sensor 6 fluctuates greatly, it can be determined that there is scoliosis at that position.

[0031] Step S04: When the sitting pressure sensor 9 detects that the sitting posture of the human body is incorrect, the human body state is judged according to the pressure distribution of the side pressure sensor 6, and the sitting posture problem of the student is analyzed. When the pressure distribution detected by the sitting pressure sensor 9 is uneven, it will inevitably lead to uneven pressure at various locations detected by the side pressure sensor 6. According to the superposition of the pressure distribution of the sitting pressure sensor 9 and the pressure distribution of the side pressure sensor 6, the sitting posture of the child can be predicted.

[0032] When it is found in step S03 or step S04 that the sitting posture of the human body is incorrect, the adjustment knob 4 at the corresponding position is adjusted according to the pressure distribution of the lateral pressure sensor 6, and the sitting posture or scoliosis is corrected by increasing the resistance in stages. When the adjustment knob 4 is adjusted for the first time, the pressure is increased a little bit, and after a period of time, when it is detected that the lateral pressure at this position decreases, the distance of the adjustment knob 4 is adjusted a little bit again, and the spine is corrected through staged adjustments.
