Description

Technical Field

[0001] This utility model relates to the field of shoe sole anti-slip testing technology, specifically to a shoe sole anti-slip testing platform. Background Technology

[0002] Existing traditional friction testing methods typically employ simple friction test benches or mechanical devices to measure the coefficient of friction by directly applying known forces (such as pressure) and a fixed test surface. These tests are usually conducted on a single horizontal plane, using standard materials (such as wood, metal, rubber, etc.) as the test surface. Traditional testing methods focus primarily on testing friction under static conditions, lacking dynamic simulation of friction, and the test conditions (such as pressure, angle, and speed) are usually fixed, failing to simulate the complex contact and interaction between the shoe sole and the ground during actual use. Furthermore, traditional techniques do not consider the dynamic changes of the shoe sole under actual gait and the frictional characteristics of different parts (such as the forefoot and heel).

[0003] In view of this, we have studied and improved upon the existing problems to provide a shoe sole anti-slip testing platform to solve the current issues. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a shoe sole anti-slip testing platform, comprising: a testing stand, a friction drive assembly, and an ankle joint assembly. The surface of the testing stand is provided with an adjustment seat, and a hydraulic rod is fixedly installed on the surface of the adjustment seat. The output end of the hydraulic rod is fixedly connected to the top end of the ankle joint assembly. The friction drive assembly includes a fixed seat, a linear slide, and a lead screw drive assembly fixed to the surface of the fixed seat for driving the linear slide linearly. The surface of the fixed seat is provided with a slot for engaging various friction coefficient testing plates. The ankle joint assembly includes a piston cylinder seat, a fixed ear seat, and a movable ankle plate. A pressure measuring rod is slidably sleeved on the bottom end of the piston cylinder seat. The bottom end of the pressure measuring rod is fixedly connected to the surface of the fixed ear seat. One end of the fixed ear seat is rotatably connected to the surface of the movable ankle plate. A deformation force gauge is fixedly installed on the surface of the fixed ear seat for measuring the rotational torque of the movable ankle plate. A pressure sensor and a bottom pressure plate are fixedly connected to the bottom surface of the movable ankle plate, and the measuring end of the pressure sensor is connected to the surface of the bottom pressure plate.

[0006] This design precisely controls the vertical downward pressure of the ankle joint assembly via a hydraulic rod, thereby adjusting the contact pressure between the sole and the test plate surface to simulate test conditions with varying friction. This design provides flexibility to the test platform, enabling the simulation of different contact states between the sole and the ground during actual use, thus improving the representativeness and accuracy of the test results.

[0007] In a preferred embodiment, this invention can be further configured such that the bottom pressure plate and the dynamic ankle plate adopt an elastic metal plate structure, the deformation force meter is used to measure the deflection force of the dynamic ankle plate, and the pressure sensor is used to measure the elastic deformation of the bottom pressure plate. By accurately measuring the rotational torque of the dynamic ankle plate caused by friction through the deformation force meter, combined with the structure of the bottom pressure plate and the pressure sensor, the deflection force and elastic deformation caused by friction can be accurately measured, providing more comprehensive friction data. This design is particularly suitable for testing the anti-slip performance of the sole in different parts (such as the ball of the foot and the heel), and can accurately reflect the true friction and anti-slip effect of the sole.

The hydraulic sensor, by measuring the hydraulic oil pressure inside the piston cylinder seat, can monitor the contact pressure between the sole and the test surface in real time. This design ensures the stability and accuracy of the forward pressure during testing, thereby making friction force measurement more precise and improving the reliability of the test bench.

[0009] In a preferred embodiment, the present invention can be further configured such that the hydraulic rod is a hydraulic drive rod structure used to drive the ankle joint assembly to move downward on the surface of the vertical friction drive assembly, and to provide vertical downward pressure to the ankle joint assembly.

[0010] The hydraulic rod design allows for precise adjustment of the speed and force of the ankle joint assembly's vertical downward movement, simulating the anti-slip performance of the sole under different friction conditions. This design enables the testing platform to perform tests of varying intensities according to actual needs, simulating the state of the sole's contact with the ground under different pressures, thus better reflecting the anti-slip performance of the sole.

[0011] In a preferred embodiment, the present invention can be further configured such that: the lead screw drive assembly is arranged horizontally, including a motor, a lead screw rotatably mounted on the surface of a fixed base, and a threaded sleeve block fixed to the bottom surface of a linear slide. The threaded sleeve block is sleeved on the surface of the lead screw. The lead screw drive assembly is used to drive the linear slide to move laterally, and the direction of movement is parallel to the bottom surface of the moving ankle plate.

[0012] The lead screw drive assembly uses a motor to drive the linear slide table for precise lateral movement, ensuring a smooth movement path for the sole during testing and making friction force measurements more reliable. This structural design allows for testing the friction performance of the sole in different directions during testing, enhancing the applicability and testing range of the equipment.

[0013] In a preferred embodiment, the present invention can be further configured such that the driving force of the hydraulic rod is adjustable, and the thrust at the output end of the hydraulic rod is controlled by adjusting the pressure of the hydraulic oil, thereby adjusting the magnitude of the vertical downward pressure of the ankle joint assembly to simulate test conditions of different friction forces.

[0014] The adjustable hydraulic drive rod design allows for flexible adjustment of the vertical downward pressure on the ankle joint assembly to simulate different ground conditions and friction states, meeting a variety of testing requirements. This design provides greater flexibility for testing the anti-slip performance of shoe soles, enabling the simulation of various states of contact between the sole and the ground in real-world environments.

[0027] Combination Figures 1-4 As shown, this utility model provides a shoe sole anti-slip testing platform, including: a testing stand 100, a friction drive assembly 200, and an ankle joint assembly 300. The surface of the testing stand 100 is provided with an adjustment seat 110, and a hydraulic rod 120 is fixedly installed on the surface of the adjustment seat 110. The output end of the hydraulic rod 120 is fixedly connected to the top end of the ankle joint assembly 300. The friction drive assembly 200 includes a fixed seat 210, a linear slide 220, and a lead screw drive assembly 230 fixed to the surface of the fixed seat 210 for driving the linear slide 220 to move linearly. The surface of the fixed seat 210 is provided with a slot for engaging various friction coefficient test plates. 221, the ankle joint assembly 300 includes a piston cylinder seat 310, a fixed ear seat 320, and a movable ankle plate 330.

One end of the fixed ear seat 320 is rotatably connected to the surface of the movable ankle plate 330. A deformation force gauge 340 is fixedly installed on the surface of the fixed ear seat 320.

A pressure sensor 332 and a bottom pressure plate 331 are fixedly connected to the bottom surface of the movable ankle plate 330, and the measuring end of the pressure sensor 332 is connected to the surface of the bottom pressure plate 331.

[0028] Description of working effect: In this embodiment, the vertical downward pressure of the ankle joint assembly 300 is precisely adjusted by the hydraulic rod 120, simulating the friction test of the sole under different ground conditions, providing more accurate friction force data. The deformation force gauge 340 torque measuring device can monitor the rotation of the dynamic ankle plate 330 under the influence of friction force in real time. Simultaneously, the elastic metal plate structure of the bottom pressure plate 331 and pressure sensor 332 allows the device to comprehensively detect the deflection force and elastic deformation caused by friction, ensuring the comprehensiveness and accuracy of the test.

[0030] Working effect description: By measuring the rotational torque of the ankle plate 330 caused by friction through the deformation force gauge 340, and combining the structure of the bottom pressure plate 331 and the elastic metal plate of the pressure sensor 332, the deflection force and elastic deformation caused by friction can be accurately measured, providing more comprehensive friction data. This design is particularly suitable for testing the anti-slip performance of different parts of the sole, such as the forefoot and heel, and can accurately reflect the true friction and anti-slip effect of the sole.

[0031] In this embodiment, a hydraulic sensor is installed inside the piston cylinder seat 310 and filled with hydraulic oil. A piston, slidably fitted onto the inner side of the piston cylinder seat 310, is located at the top of the pressure measuring rod 311. This piston is used to measure the pressure between the sole and the test plate surface based on the hydraulic pressure inside the piston cylinder seat 310. The hydraulic sensor, by measuring the hydraulic oil pressure inside the piston cylinder seat 310, can monitor the contact pressure between the sole and the test surface in real time. This design ensures the stability and accuracy of the forward pressure during testing, resulting in more precise friction measurement and improved reliability of the test bench.

This design allows the test bench to perform tests of varying intensities according to actual needs, simulating the state of the sole in contact with the ground under different pressures, thereby better reflecting the anti-slip performance of the sole.

The threaded sleeve is fitted onto the surface of the lead screw. The lead screw drive assembly 230 is used to drive the linear slide 220 to move laterally, and the direction of movement is parallel to the bottom surface of the movable ankle plate 330. The lead screw drive assembly 230 drives the linear slide 220 to perform precise lateral movement through the motor, ensuring a smooth movement path of the sole during the test and making the friction measurement during the test more reliable. Through this structural design, the friction performance of the sole in different directions can be tested during the test, enhancing the applicability and testing range of the equipment.

[0034] In this embodiment, the driving force of the hydraulic rod 120 is adjustable. The thrust at the output end of the hydraulic rod 120 is controlled by adjusting the pressure of the hydraulic oil, thereby adjusting the magnitude of the vertical downward pressure of the ankle joint assembly 300 to simulate test conditions with different friction forces. Through the adjustable hydraulic drive rod design, the magnitude of the vertical downward pressure of the ankle joint assembly 300 can be flexibly adjusted according to different friction force test requirements, thus simulating different ground conditions and friction states to meet various test requirements. This design provides greater flexibility for testing the anti-slip performance of shoe soles, enabling the simulation of various states of contact between the shoe sole and the ground in a real environment.
