Description

Technical Field

[0001] This utility model relates to the field of medical measurement device technology, and in particular to a shoe sole pressure distribution testing device for simulating walking. Background Technology

[0002] With the increasing awareness of health and the development of disciplines such as sports science and biomechanics, the study of plantar pressure distribution has become increasingly important. Plantar pressure distribution refers to the pressure pattern generated when a person stands or walks, and understanding plantar pressure distribution can help prevent and treat foot diseases, optimize footwear design, improve the performance of sports equipment, evaluate rehabilitation effects, and enhance athletes' performance.

[0003] Patent CN214434202U discloses a foot pressure distribution measuring device, including a housing and a battery box. The housing contains a detection plate, and a control box is mounted on one side of the detection plate. A hinge is mounted above the control box, and a cover is located above the hinge. A screw is located inside the cover, and a handle is mounted to the left of the screw. While this device can measure static pressure distribution by having the patient stand still or on one leg, it may not provide accurate data for changes in foot pressure during walking or other dynamic activities. Because people's walking postures vary, the pressure distribution on the sole of the foot changes rapidly with each step. Relying solely on static measurement results to analyze foot biomechanical characteristics may miss important dynamic information, leading to an incomplete and inaccurate diagnosis. Utility Model Content

[0004] To address the problems of the prior art, this invention provides a shoe sole pressure distribution testing device for simulating walking, enabling dynamic testing of the pressure distribution on the sole of the shoe during simulated walking.

[0005] The technical solution is as follows: A shoe sole pressure distribution testing device for simulating walking includes a base plate, support columns, and a support plate. The base plate is the load-bearing carrier of the testing device. Multiple support columns are provided and fixedly installed on the top surface of the base plate. The support plate is fixedly installed on the base plate by multiple support columns and serves as the carrier for placing the user's foot. It also includes: two guide plates, symmetrically fixedly installed on both sides of the top surface of the support plate, each guide plate having a groove on its upper part; and a sliding frame, slidably installed between the two guide plates, with both ends of the sliding frame located within the grooves of the guide plates. Elastic elements are provided between the guide plates and the sliding frame. Four pulleys are provided and rotatably mounted at intervals on the bottom of the sliding frame. The fixed pulleys are arranged in pairs and symmetrically distributed on the left and right sides of the sliding frame. Each fixed pulley is wound with a loop belt. The footrest is located between two belts in the same group. Two fixed pulleys are symmetrically rotatably mounted on the outer walls of both sides of the footrest. The fixed pulleys are connected to the corresponding fixed pulleys of the footrest in the same group via belts. Under the action of the elastic element, the bottom surface of the footrest does not contact the support plate when the belt is at its free length. Pressure sensors are densely arranged on the footrest surface. The pressure sensors are used to sense the pressure distribution of the user stepping on the footrest.

[0006] As a further preferred embodiment, the bottom of the foot support is provided with an anti-slip textured coating, and both the foot support and the pressure sensor thereon are supported by flexible materials. The foot support and the pressure sensor thereon can adapt to changes in the shape of the foot while maintaining high sensitivity and accuracy.

[0007] As a further preferred embodiment, the elastic element includes a connecting plate and a spring. The connecting plate is fixed on the sides of the two guide plates facing each other at their tops. A spring is provided between the connecting plate and the sliding frame. The spring acts on the sliding frame, so that the sliding frame is initially at the top of the groove of the guide plate. When the user's two feet step on the footrest at the same time, the footrest pulls the spring downward through the belt and the sliding frame until the footrest is supported by the support plate, so that the footrest can fit tightly against the user's soles, improving the accuracy of the pressure sensor in monitoring the pressure at various points on the soles of the feet.

[0008] As a further preferred embodiment, symmetrical pivots are installed on the top surface of the base plate on both sides of the support plate. The pivots do not contact the support plate. A conveyor belt is wound between the two pivots. The support plate is supported on the upper part of the conveyor belt. The contact surfaces of the conveyor belt and the footrest are rough surfaces. The conveyor belt can roll against the support plate. The user steps on the footrest with both feet, so that the footrest contacts the conveyor belt to simulate walking.

[0009] As a further preferred embodiment, the system also includes motors. Two motors are symmetrically fixedly mounted on the base plate. The output shaft of each motor is connected to a corresponding rotating shaft on the same side. The motors synchronously drive the rotating shafts to rotate, so that the conveyor belt on the rotating shafts can move automatically, thereby automatically simulating walking and testing the distribution of plantar pressure.

[0010] As a further preferred embodiment, each footrest has a ring of airbags on its inner bottom wall, and each guide plate is equipped with an air pump. The air pump's air inlet is connected to the corresponding airbag on the same side via a connecting pipe. The air pump draws air into the airbag through the connecting pipe, allowing the airbag to expand or contract, thus enabling the airbag to adapt to different users' foot sizes on the footrest and further improving the fit between the user's foot and the pressure sensor on the footrest.

[0011] The beneficial effects are: 1. By densely setting pressure sensors on the foot support surface of the foot support, this utility model can accurately sense the pressure distribution of the user stepping on the foot support. With the help of the sliding frame and the elastic element, the foot support will only fit tightly against the user's foot when the user's foot applies pressure, thus ensuring the accuracy of the measurement.

[0012] 2. Through the design of the conveyor belt and motor, this utility model can automatically simulate walking, so that when the user's feet step on the footrest, the conveyor belt can be driven to roll as if walking, thus more accurately reflecting the pressure distribution of the soles of the feet during walking.

[0013] 3. This utility model can also control the airbag with an air pump to adapt to different users' foot sizes, and ensure smooth movement through structures such as fixed pulleys and belts, reducing discomfort during the testing process. Attached Figure Description

It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0020] A device for testing the plantar pressure distribution of shoes to simulate walking, such as... Figures 1-4 As shown, the device includes a base plate 1, support columns 101, and support plate 2. The base plate 1 is the load-bearing carrier of this testing device. Multiple support columns 101 are provided and fixedly installed on the top surface of the base plate 1. The support plate 2 is fixedly installed on the base plate 1 by multiple support columns 101 and serves as the carrier for the user's feet. The device also includes: guide plates 3, two of which are symmetrically fixedly installed on both sides of the top surface of the support plate 2. Each guide plate 3 has a groove on its upper part; a sliding frame 4, slidably installed between the two guide plates 3, with both ends of the sliding frame 4 located within the grooves of the guide plates 3. Elastic elements are provided between the guide plates 3 and the sliding frame 4; and four fixed pulleys 7, which are rotatably installed at intervals on the bottom of the sliding frame 4. The fixed pulleys 7 are arranged in groups of two and symmetrically distributed on the left and right sides of the sliding frame 4. Each wheel is wound with a ring-shaped belt 8; the footrest 9 is located between the two belts 8 in the same group, and two fixed pulleys 71 are symmetrically and rotatably installed on the outer walls of both sides of the footrest 9. The fixed pulleys 71 are connected to the fixed pulleys 71 of the corresponding footrest 9 in the same group through the belts 8. Under the action of the elastic element, the bottom surface of the footrest 9 does not contact the support plate 2 when the belt 8 is at its free length; pressure sensors 10 are densely arranged on the foot support surface of the footrest 9. The pressure sensors 10 are used to sense the pressure distribution of the user stepping on the footrest 9; the bottom of the footrest 9 is provided with an anti-slip textured coating. The footrest 9 and the pressure sensors 10 on it are both supported by flexible materials. The footrest 9 and the pressure sensors 10 on it can adapt to changes in the shape of the foot while maintaining high sensitivity and accuracy.

[0021] like Figure 2 and Figure 3As shown, the elastic element includes a connecting plate 5 and a spring 6. The connecting plate 5 is fixed on the side of the top of the two guide plates 3 facing each other. The spring 6 is provided between the connecting plate 5 and the sliding frame 4. The spring 6 acts on the sliding frame 4, so that the sliding frame 4 is initially at the top of the groove of the guide plate 3. When the user's two feet step on the foot support 9 at the same time, the foot support 9 pulls the spring 6 downward through the belt 8 and the sliding frame 4 until the foot support 9 is supported by the support plate 2, so that the foot support 9 can fit tightly against the user's foot, improving the ability of the pressure sensor 10 to accurately monitor the pressure at various points on the foot.

[0022] like Figure 1 As shown, symmetrical rotating shafts 11 are installed on the top surface of the base plate 1 on both sides of the support plate 2. The rotating shafts 11 do not contact the support plate 2. A transmission belt 12 is wound between the two rotating shafts 11. The support plate 2 is supported on the upper part of the transmission belt 12. The contact surfaces of the transmission belt 12 and the foot support 9 are rough surfaces. The transmission belt 12 can roll against the support plate 2. The user steps on the foot support 9 with both feet, so that the foot support 9 contacts the transmission belt 12 to simulate walking. It also includes motors 13. Two motors 13 are symmetrically fixed on the base plate 1. The output shaft of the motor 13 is connected to the corresponding rotating shaft 11 on the same side. The motor 13 synchronously drives the rotating shaft 11 to rotate, so that the transmission belt 12 on the rotating shaft 11 can move automatically, thereby automatically simulating walking and testing the distribution of foot pressure.

[0023] like Figure 1 and Figure 4 As shown, an airbag 15 is provided on the inner side wall of the bottom of the foot support 9, and an air pump 14 is installed on the guide plate 3. The air inlet of the air pump 14 is connected to the corresponding airbag 15 on the same side through the connecting pipe 16. The air pump 14 draws air into the airbag 15 through the connecting pipe 16. The airbag 15 can expand or contract, so that the airbag 15 can adapt to the foot size of different users on the foot support 9, further improving the tightness of the fit between the user's foot and the pressure sensor 10 on the foot support 9.

[0024] When using this device to conduct a foot pressure distribution test, the user first places both feet on the footrest 9 on the support plate 2. The footrest 9 is connected to the sliding frame 4 via the belt 8 and moves downward, thereby compressing the spring 6 until the footrest 9 is supported by the transmission belt 12 on the support plate 2. This ensures that the footrest 9 can closely conform to the shape of the user's foot. At the same time, the anti-slip textured coating on the bottom of the footrest 9 and the pressure sensor 10 made of flexible material ensure good contact with the foot, improving the sensitivity and accuracy of pressure sensing. Meanwhile, the air pump 14 performs appropriate inflation or deflation adjustments to ensure that the inner wall of the bottom of the footrest 9 is properly inflated. The airbag 15 further enhances the fit between the foot support 9 and the foot according to the user's foot size, ensuring the reliability of pressure distribution data acquisition. Once the user is standing firmly, the motor 13 starts to work, driving the rotating shaft 11 to rotate, which in turn drives the transmission belt 12 to roll. The transmission belt 12 is stably supported by the support plate 2 and moves with the rotation of the rotating shaft 11, simulating the relative movement of the sole of the foot and the ground during walking. The user stands on the foot support 9 and walks synchronously. As the transmission belt 12 rolls, the pressure sensors 10, which are densely distributed on the foot support 9, can monitor and record the pressure distribution of various parts of the sole of the foot in real time when the user is walking.
