[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 11 The present invention provides a technical solution: Example 1: A foot pressure distribution measurement structure for gait training, comprising: a gait training treadmill 1.

[0021] Specifically, a recessed groove 11 is formed on the surface of the gait training machine treadmill 1, and a treadmill conveyor belt 2 is installed inside the recessed groove 11. The relative positions of the gait training machine treadmill 1 and the treadmill conveyor belt 2 can be as follows: Figure 1 As shown, the upper surface of the treadmill conveyor belt 2 is lower than the upper surface of the gait training device treadmill 1; Secondly, a conveyor belt support frame 3 is installed inside the treadmill conveyor belt 2. The conveyor belt support frame 3 is mainly used to support the treadmill conveyor belt 2, ensuring that the user can stand on the upper surface of the treadmill conveyor belt 2 and avoid excessive deformation of the treadmill conveyor belt 2. A pressure measuring component 4 is installed between the conveyor belt support frame 3 and the upper part of the treadmill conveyor belt 2. The pressure measuring component 4 includes a two-layer structure of mounting base plate 5 and mounting partition plate 6. The pressure measuring component 4 is mainly used to monitor the user's foot pressure in a timely and accurate manner. The specific structure of mounting base plate 5 and mounting partition plate 6 is shown below. Multiple pressure sensors 52 arranged in a rectangular array are fixedly mounted on the mounting base plate 5. These pressure sensors 52 are widely used high-performance sensors in the prior art. Their core principle is to convert the physical quantity of pressure (or pressure difference) into a proportional change in capacitance, which is then converted into a standard electrical signal (such as voltage, current, or digital signal) for output via a measuring circuit. The pressure sensors 52 feature high precision, high stability, low power consumption, and strong overload resistance, making them suitable for the precise and reliable plantar pressure measurement required by this device. By setting multiple pressure sensors 52, they can contact the entire sole of the user's foot. The pressure monitored by each pressure sensor 52 is collected, and then... The location of the pressure sensor 52 can accurately simulate the pressure distribution on the user's feet. A guide groove 61 is vertically opened in the middle of the mounting partition 6, located directly above the pressure sensor 52. A matching limiting slider 63 is vertically slidably installed in the inner cavity of the guide groove 61. The limiting slider 63 can slide vertically up and down in the inner cavity of the guide groove 61. The limiting slider 63 moves down and applies pressure to the pressure sensor 52. A rolling wheel 64 is rotatably installed on the upper part of the limiting slider 63. The upper part of the rolling wheel 64 protrudes from the upper surface of the limiting slider 63, and the upper part of the rolling wheel 64 abuts against the upper inner wall of the treadmill conveyor belt 2. The rolling wheel 64 is designed to reduce the friction force on the treadmill conveyor belt 2 during transmission. When using this device, the user stands on the upper surface of the treadmill conveyor belt 2. Multiple limiting sliders 63 corresponding to the user's feet are squeezed and moved downwards, thereby generating a squeezing force on the pressure sensors 52 below the limiting sliders 63. By collecting the pressure magnitude monitored by these pressure sensors 52 and the location of these pressure sensors 52 themselves, the static foot pressure distribution of the user can be accurately simulated. When the user walks on the treadmill conveyor belt 2, the treadmill conveyor belt 2 itself maintains transmission and conveying. At this time, the stable correspondence between the user's feet and the pressure sensors 52 is no longer maintained. Since the position of the user's feet will change, by collecting the pressure monitored by multiple pressure sensors 52 over a larger range and analyzing the pressure changes of the pressure sensors 52, and by controlling the time variable, the dynamic foot pressure distribution of the user can be simulated.

[0022] To facilitate the installation and positioning of the pressure measuring component 4, this application further includes a receiving groove 31 on the upper surface of the conveyor belt support frame 3. The depth of the receiving groove 31 is slightly less than the overall thickness of the pressure measuring component 4, ensuring that the rolling wheel 64 can abut against the inner wall of the upper part of the running platform conveyor belt 2. A limit block 32 is fixedly installed on the inner side wall of the receiving groove 31, and a limit groove 41 corresponding to and adapted to the limit block 32 is provided at the edge of the pressure measuring component 4. Figure 4As shown, the limiting block 32 and the limiting slot 41 are used to initially limit the horizontal position of the pressure measuring component 4, so that the pressure measuring component 4 can be installed and positioned with the conveyor belt support frame 3. The pressure measuring component 4 is fixedly connected to the bottom of the receiving slot 31 by bolts at the edge. Therefore, the relative positions of the mounting base plate 5, the mounting partition plate 6 and the conveyor belt support frame 3 can be fixed. On the one hand, it can prevent the pressure measuring component 4 from jumping as a whole. On the other hand, it can also prevent horizontal misalignment between the pressure sensor 52 and the limiting slider 63. This ensures that when the rolling wheel 64 is pressed and drives the limiting slider 63 to slide down, the limiting slider 63 only squeezes one pressure sensor 52 below it, thereby improving the accuracy of the measurement.

[0023] In order to install and tighten the running platform conveyor belt 2, this application also has mounting grooves 33 at both ends of the conveyor belt support frame 3. The inner cavity of the mounting groove 33 is rotatably mounted with a transmission roller 34. The two transmission rollers 34 support the two ends of the running platform conveyor belt 2 respectively, thereby ensuring that the running platform conveyor belt 2 is always in a taut state and avoiding slack. A drive motor is provided at the shaft end of one of the transmission rollers 34 to drive its rotation. The drive motor (not shown in the figure) drives the transmission roller 34 to rotate. This is the prior art and will not be described in detail here.

[0024] To reduce the friction experienced by the conveyor belt 2 during transmission, this application further includes a receiving groove 35 on the lower surface of the conveyor belt support frame 3. Multiple support rollers 36, evenly spaced, are rotatably mounted within the receiving groove 35. The lower parts of the support rollers 36 abut against the lower inner wall of the conveyor belt 2. Figure 8 As shown, since the running platform conveyor belt 2 is wrapped around the outside of the conveyor belt support frame 3, the friction between the inner wall of the lower part of the running platform conveyor belt 2 and the conveyor belt support frame 3 can be reduced by setting the support shaft roller 36, thereby ensuring that the transmission and conveying of the running platform conveyor belt 2 is smoother.

[0025] To facilitate the installation of the limiting slider 63, this application further includes a limiting groove 62 formed on the inner wall of the guide groove 61, and a limiting protrusion 65 fixed to the outer wall of the limiting slider 63. The limiting protrusion 65 is vertically slidably installed in and adapted to the inner cavity of the limiting groove 62. Figure 6 and Figure 7As can be seen, a total of three limiting bumps 65 are provided on the side wall of a limiting slider 63. One limiting bump 65 is located on one side surface of the limiting slider 63, and the other two limiting bumps 65 are located on the other side surface opposite thereto. Three limiting chutes 62 are provided on the two inner side walls opposite to the guiding through groove 61, so as to ensure that no movement interference occurs between the multiple limiting bumps 65 after the multiple limiting sliders 63 are installed. An inclined notch 651 is provided at the lower end of the limiting bump 65. When the limiting slider 63 is installed, it is pressed downward from the upper opening of the guiding through groove 61. At this time, the inclined notch 651 will squeeze the inner side wall of the guiding through groove 61 to slightly deform until the limiting bump 65 corresponds to the limiting chute 62 and then restores the deformation, thereby preventing the limiting slider 63 from easily withdrawing from the inner cavity of the guiding through groove 61. A buffer pad 66 is fixed on the lower surface of the limiting slider 63. The buffer pad 66 is used to buffer the impact received by the pressure sensor 52, so as to improve the stability of the pressure data measured by the pressure sensor 52.

[0026] In order to install and connect the rolling wheel 64 with the limiting slider 63, the present application further has a roller groove 631 opened on the upper surface of the limiting slider 63. An axial hole 632 is opened on the inner side wall of the roller groove 631. The lower half of the rolling wheel 64 is located in the inner cavity of the roller groove 631 and is adapted thereto. The end of the rotating shaft of the rolling wheel 64 is rotatably inserted into the inner cavity of the axial hole 632, as Figure 7 As can be seen, the settings of the roller groove 631 and the axial hole 632 are mainly used for installing and positioning the rolling wheel 64, ensuring that the rolling wheel 64 can only rotate on the upper part of the limiting slider 63 and will not be separated therefrom.

[0027] In order to adapt to users of different heights, the conveyor belt support frame 3 of the present application is fixedly installed in the inner cavity of the recessed groove 11. A telescopic frame 12 is installed at the edge of the upper surface of the gait training instrument treadmill 1. An armrest 13 is fixedly installed on the upper part of the telescopic frame 12. The telescopic frame 12 is arranged in a "匚"-shaped structure with the opening downward, and the telescopic frame 12 can be lifted and lowered by itself to facilitate adapting to users of different heights.

[0028] To process the monitoring data from the pressure sensor 52, this application also includes a control host 7 installed outside the gait training treadmill 1. An interactive display 71 is mounted on the top of the control host 7. The control host 7 receives the data monitored by the pressure sensor 52, processes it, and then displays the user's actual gait in the form of an image on the interactive display 71 for the user's reference and understanding of their own condition. A projector 72 is installed on the surface of the control host 7, and the projector 72 faces the upper surface of the treadmill conveyor belt 2. The projector 72 acts as a projection device to project reasonable and standardized footprints onto the upper surface of the treadmill conveyor belt 2 for the user to correct their gait. A side bracket 14 is fixedly installed on the side of the gait training treadmill 1, and a control PC 15 is installed on the top of the side bracket 14. The control PC 15 and the control host 7 maintain a communication connection through a wireless transmission module. The settings of the control PC 15 allow the user to adjust parameters such as the position, angle, and size of the footprints projected by the projector 72, and to record various parameters and trends of their own gait during correction and rehabilitation.

[0029] To ensure that the limiting slider 63 exerts downward pressure on the pressure sensor 52 when pressed down, this application also includes a sealing cylinder 51 fixedly installed on the mounting base plate 5. The sealing cylinder 51 itself is a hollow structure, and a through hole 54 is opened through the surface of the mounting base plate 5. The sealing cylinder 51, the through hole 54, and the pressure sensor 52 are arranged in a corresponding order from top to bottom. A sealing plug 511 is slidably installed in the inner cavity of the mounting base plate 5. A piston rod 512 is fixed on the upper surface of the sealing plug 511. The upper end of the piston rod 512 extends above the sealing cylinder 51 and is fixed with a pressure plate 513. The upper surface of the pressure plate 513 is in contact with the lower surface of the limiting slider 63, thus limiting the slider... When block 63 slides downward, the limiting slider 63 will press down on the pressure plate 513, thereby causing the sealing plug 511 to move downward in the inner cavity of the sealing cylinder 51. A spring 515 is provided on the lower surface of the sealing plug 511. The lower end of the spring 515 passes through the through hole 54 and is fixed with an end plate 516. The end plate 516 presses on the upper surface of the pressure sensor 52. When the sealing plug 511 moves downward, the sealing plug 511 will compress the spring 515. The spring 515 generates elastic force on the end plate 516, which can apply downward squeezing force to the pressure sensor 52, thereby ensuring that when the limiting slider 63 moves downward, it can indirectly generate downward pressure on the pressure sensor 52.

[0030] To prevent the pressure sensor 52 around the user's feet from generating measurement data, this application also includes a bellows 514 fixedly disposed between the lower surface of the sealing plug 511 and the bottom of the sealing cylinder 51, and the bellows 514 is sleeved on the outside of the spring 515, such as... Figure 10As shown, the bellows 514 is provided to ensure the sealing of the inner cavity of the sealing cylinder 51 and to ensure that the medium in the inner cavity of the sealing cylinder 51 will not leak when the sealing plug 511 moves down. Four connecting pipes 53 arranged in a ring array are provided at the bottom of the sealing cylinder 51. The two ends of the connecting pipes 53 are respectively connected to the inner cavities of two adjacent sealing cylinders 51. Since the sealing plug 511 under the user's feet will move downward, the medium in the inner cavity of the sealing cylinder 51 can be squeezed into the inner cavity of the adjacent sealing cylinder 51 through the connecting pipes 53, thereby pushing the sealing plug 511 in the inner cavity of the adjacent sealing cylinder 51 to move slightly upward. The advantages of the above design are: combining Figure 11 As shown, when the user's feet are standing on the upper surface of the treadmill conveyor belt 2, the area of ​​the treadmill conveyor belt 2 directly below the feet will move downwards, while the area of ​​the treadmill conveyor belt 2 around the feet will tilt due to the tension of the treadmill conveyor belt 2. Figure 11 The upper part of the device causes the sealing plug 511 around the foot to be squeezed downwards, resulting in the pressure sensor 52 around the foot also generating measurement data. Therefore, the footprint pattern displayed on the interactive display 71 will be larger than the user's actual footprint. Since the device connects the inner cavities of all adjacent sealing cylinders 51 through the connecting tube 53, the sealing plugs 511 not directly under the user's foot will move slightly upwards due to the increased pressure inside the sealing cylinder 51. This counteracts the downward pressure on the sealing plugs 511 when the treadmill conveyor belt 2 is tightened, ensuring that other pressure sensors 52 outside the area directly under the user's foot will not generate measurement data. Figure 11 The lower part), thereby ensuring that the footprint pattern displayed on the interactive display 71 is closer to the actual footprint pattern; finally, a limit ring 517 is fixed in the lower half of the inner wall of the sealing cylinder 51, which can be used to limit the downward movement of the sealing plug 511.
