Description

Technical Field

[0001] This utility model relates to the field of shoe abrasion resistance testing technology, specifically an outdoor shoe abrasion resistance testing device. Background Technology

[0002] When people wear shoes, due to differences in individual walking habits or postures and the environment they are in, the shoe materials are in a complex frictional environment. However, existing friction tests for shoe materials are difficult to comprehensively test the friction of shoe materials and are difficult to simulate and reproduce the complex frictional environment when people are active.

[0003] Therefore, this utility model provides an outdoor shoe abrasion resistance testing device to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this invention is that existing testing devices cannot flexibly simulate the complex friction environment during human activities.

[0005] This utility model provides the following technical solution: an outdoor shoe abrasion resistance testing device, including a frame, an adjustment component and a friction component. The adjustment component is installed on the frame, and the friction component is installed below the adjustment component on the frame. The adjustment component simulates walking abrasion posture by cooperating with the reciprocating planar friction of the friction component through its own circumferential rotation and radial reciprocating movement.

[0006] The adjustment assembly includes a degree-of-freedom platform, a first drive motor, and a rotating shaft. The degree-of-freedom platform is fixedly installed below the frame, and the first drive motor is fixedly installed on the surface of the degree-of-freedom platform. A rotating shaft, coaxially fixed with the first drive motor, is rotatably installed through the degree-of-freedom platform below it, and a mold is fixedly installed at the end of the rotating shaft.

[0007] A first electric push rod is fixedly installed between the rotating shaft and the mold.

[0008] The friction assembly includes a second drive motor, a disc, a connecting rod, and a friction body. The second drive motor is fixedly installed below the frame. The output shaft of the second drive motor is fixedly installed on the disc. One end of the connecting rod is eccentrically hinged to the surface of the disc. The other end of the connecting rod is hinged to one side of the friction body. The friction body is slidably installed inside the frame.

[0009] The friction body includes a base and a friction layer. The base is slidably installed inside the frame, and the friction layer is fixedly installed on the surface of the base.

[0010] A second electric push rod is fixedly installed on the frame, and a slide plate is slidably installed inside the frame. A second drive motor is fixedly installed on the slide plate, and the end of the second electric push rod is fixedly connected to the surface of the slide plate.

[0011] The surface of the friction body is fixedly fitted with multiple friction layers with different friction coefficients.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By adjusting the combination of the component and the friction component, this utility model can improve the accuracy of the test by making the friction component perform reciprocating uniform friction on the shoe material. At the same time, it can flexibly switch different friction coefficients to simulate different environmental friction. The adjustment component can make the shoe material deflect at multiple angles and rotate circumferentially and cooperate with the friction component to conduct wear resistance test. This can further simulate the friction environment of people during different activities, which is conducive to flexibly, comprehensively and realistically simulating the friction or wear of shoe materials during actual use.

[0014] 2. In addition to the adjustment component and friction component working together to test the shoe material, the friction component can also drive the shoe material to cyclically extend and retract through the first push rod to apply pressure to the shoe material, thereby simulating the wear and tear on the shoe material caused by a person's walking posture, thus improving the abrasion resistance test effect of the shoe material and enabling a more comprehensive and realistic abrasion resistance test.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Example 1: In view of the technical problem that existing testing devices cannot fully simulate the complex friction environment during human activities, resulting in test data that is difficult to closely reflect the wear and tear of actual use, this embodiment of the present disclosure provides an outdoor shoe abrasion resistance testing device, including a frame 1, an adjustment component 2, and a friction component 3. The adjustment component 2 is installed on the frame 1, and the friction component 3 is installed below the adjustment component 2. The adjustment component 2 simulates the walking wear posture by cooperating with the reciprocating planar friction of the friction component 3 through its own circumferential rotation and radial reciprocating movement.

[0025] The adjustment component 2 includes a degree-of-freedom platform 21, a first drive motor 22, a rotating shaft 23, and a mold 24. The degree-of-freedom platform 21 is fixedly installed below the frame 1. The first drive motor 22 is fixedly installed on the surface of the degree-of-freedom platform 21. The rotating shaft 23, which is coaxially fixed with the first drive motor 22, is rotatably installed through the bottom of the degree-of-freedom platform 21. The mold 24 is fixedly installed at the end of the rotating shaft 23.

[0026] It should be noted that the mold 24 adopts the foot bionic mold 24 in the prior art, so as to better simulate the real use of shoe materials.

[0027] When testing the abrasion resistance of shoe materials, the operator controls the free platform 21 to drive the first drive motor 22, the rotating shaft 23 and the mold 24 to tilt at multiple angles and rotate slightly in the circumference. This allows the shoe materials to be flipped at different angles to test their abrasion resistance, thus enabling a comprehensive abrasion resistance simulation test.

[0028] It should be noted that the freedom platform 21 in this embodiment is a six-degree-of-freedom platform 21, which improves the friction test effect by allowing the first drive motor 22, the rotating shaft 23, and the mold 24 to deflect at multiple angles through the greater angular flexibility of the six-degree-of-freedom platform 21. Furthermore, the six-degree-of-freedom platform 21 can move along the z-axis, that is, it can drive the first drive motor 22, the rotating shaft 23, and the mold 24 to rise and fall, thereby causing the mold 24 to move radially along the rotating shaft 23. This allows the six-degree-of-freedom platform 21 to drive the first drive motor 22, the rotating shaft 23, and the mold 24 to periodically move radially, applying pressure to the shoe material. This simulates the pressure exerted on the shoe material by the foot during walking, and also simulates the wear and tear caused by a person walking on the shoe material, thus facilitating comprehensive simulation testing of the shoe material.

[0029] While the platform 21 drives the first drive motor 22, the rotating shaft 23 and the mold 24 to rotate and rub at different angles to conduct all-round friction tests and simulate the pressure of foot walking to test wear resistance, the operator can also start the first drive motor 22 to drive the rotating shaft 23 and the mold 24 to rotate, thereby causing the mold 24 and the shoe material to rotate circumferentially. This circumferential rotation of the mold 24 and the shoe material allows for a more comprehensive and realistic test of the wear resistance of the shoe material, which is conducive to more realistically and comprehensively simulating real sports scenarios, such as forefoot rolling, sudden stops and turns during running.

[0030] The friction assembly 3 includes a second drive motor 31, a disc 32, a connecting rod 33, and a friction body 34. The second drive motor 31 is fixedly installed below the frame 1. The output shaft of the second drive motor 31 is fixedly installed on the disc 32. One end of the connecting rod 33 is eccentrically hinged to the surface of the disc 32. The other end of the connecting rod 33 is hinged to one side of the friction body 34. The friction body 34 is slidably installed inside the frame 1.

[0031] It should be noted that, in this embodiment of the present disclosure, the frame 1 is provided with a receiving groove, the friction body 34 slides in the receiving groove, and the receiving groove is provided with a guide rail groove to keep the friction body 34 sliding stably through the guide rail groove.

[0032] The friction body 34 includes a base 341 and a friction layer 342. The base 341 is slidably installed inside the frame 1, and the friction layer 342 is fixedly installed on the surface of the base 341.

[0033] The friction layer 342 is sandpaper. In this embodiment, the friction layer 342 uses p60-p240 sandpaper. Taking a shoe sole with a normal pressure of 30N and a rubber hardness of 65 as an example, the average static friction coefficient of p60 sandpaper is 1.1-1.3μ and the average dynamic friction coefficient is 0.9-1.1μ; the average static friction coefficient of p120 sandpaper is 0.8-1.0μ and the average dynamic friction coefficient is 0.7-0.9μ; and the average static friction coefficient of p240 sandpaper is 0.6-0.8μ and the average dynamic friction coefficient is 0.5-0.7μ.

[0034] The friction layer 342 can be fixed to the surface of the substrate 341 by any method in the prior art that can fix sandpaper, such as using a clamp, adhesive, magnetic attraction, or vacuum adsorption method that can hold sandpaper. Here, the fixing methods that are very mature in the prior art will not be described in detail.

[0035] When conducting abrasion resistance tests on shoe materials, the operator starts the second output motor, which drives the disc 32 to rotate. The rotation of the disc 32 drives the friction body 34 to reciprocate through the eccentrically hinged connecting rod 33. The reciprocating friction body 34 then performs a friction test on the bottom of the shoe material. This reciprocating planar friction achieves uniform friction, avoiding localized excessive wear or defects in the shoe material that could lead to distorted test results and deviations.

[0036] Example 2: The following only describes the differences from Example 1, and the similarities will not be repeated.

[0037] To reduce costs, in this embodiment, the degree-of-freedom platform 21 can also be a degree-of-freedom platform 21 without Z-axis movement, i.e., unable to drive the first drive motor 22, the rotating shaft 23, and the mold 24 to rise or fall. Alternatively, if the degree-of-freedom platform 21 can perform Z-axis movement and rise or fall, in order to improve the effect of simulating the pressure applied to the shoe material during foot walking, a first electric push rod 25 is fixedly installed between the rotating shaft 23 and the mold 24. The extension and retraction of the first electric push rod 25 can better drive the first drive motor 22, the rotating shaft 23, and the mold 24 to rise or fall, and can periodically drive the mold 24 to apply pressure to the shoe material, thereby improving the effect of simulating the pressure applied to the shoe material during foot walking, which is beneficial to improving the effect of shoe material abrasion resistance testing.

[0038] The friction body 34 has multiple friction layers 342 with different friction coefficients fixedly installed on its surface. Different friction coefficients can simulate the friction under different environments, thereby enabling the testing of the abrasion resistance of the shoe material under different environmental conditions, and thus enabling a more comprehensive and realistic test of the abrasion resistance of the shoe material.

[0039] A second electric push rod 35 is fixedly installed on the frame 1, and a slide plate 36 is slidably installed inside the frame 1. A second drive motor 31 is fixedly installed on the slide plate 36, and the end of the second electric push rod 35 is fixedly connected to the surface of the slide plate 36.

[0040] It should be noted that the receiving groove 11 inside the frame 1 is slidably mounted with a slide plate 36 through the guide rail groove 12. Through the extension and retraction of the second electric push rod 35, the slide plate 36 and the second drive motor 31 can be driven to move horizontally, thereby enabling the second drive motor 31 and the friction body 34 to move horizontally synchronously and switch different friction layers 342 to rub the shoe material.

[0041] Working process: When conducting abrasion resistance testing on shoe materials, the operator can activate the second electric push rod 35, which in turn drives the friction component 3 to move horizontally through the extension and retraction of the second electric push rod 35. This allows the friction body 34 to switch between different friction zones during reciprocating movement to conduct abrasion resistance testing on the shoe materials. Furthermore, it allows for flexible switching between friction layers 342 with different coefficients of friction to conduct abrasion resistance testing on the shoe materials. This is beneficial for simulating abrasion resistance under different environments and the staged wear of shoe materials, thus enabling a more comprehensive and realistic test of the abrasion resistance of shoe materials under different environments.

[0042] During abrasion resistance testing of shoe materials, the operator activates the free-degree-of-freedom platform 21 to drive the first drive motor 22, rotating shaft 23, and mold 24 to tilt and slightly rotate at multiple angles. This allows the shoe material to be flipped at different angles for friction testing of abrasion resistance, enabling comprehensive abrasion resistance simulation testing. Simultaneously, the operator can also activate the first drive motor 22 to rotate the rotating shaft 23 and mold 24, causing the mold 24 and shoe material to rotate circumferentially. This circumferential rotation of the mold 24 and shoe material allows for a more comprehensive and realistic abrasion resistance test, facilitating a more realistic and comprehensive simulation of real-world sports scenarios, such as forefoot rolling, sudden stops, and turns during running. Furthermore, during friction testing, the extension and retraction of the first electric push rod 25 can better drive the first drive motor 22, rotating shaft 23, and mold 24 to rise and fall, thereby improving the effect of simulating the pressure applied to the shoe material during foot walking. This better simulates the wear and tear caused by the pressure exerted on the shoe material by the tester walking, thus improving the overall simulation testing effect of the shoe material.

[0043] While the operator controls and adjusts the mold 24, the second drive motor 31 is activated to rotate the disc 32. The rotation of the disc 32 drives the friction body 34 to reciprocate through the eccentrically hinged connecting rod 33. This reciprocating friction body 34 performs a friction test on the bottom of the shoe material, achieving uniform friction through reciprocating planar friction and avoiding distortion of test results due to excessive local wear or local defects in the shoe material. Furthermore, during the abrasion resistance test of the shoe material, the second electric push rod 35 is activated to extend and retract, causing the friction assembly 3 to move horizontally. This allows the friction body 34 to switch between different friction zones during reciprocating movement to perform abrasion resistance testing on the shoe material. This enables flexible switching between friction layers 342 with different friction coefficients to simulate abrasion resistance under different environments and the staged wear of the shoe material, thus providing a more comprehensive and realistic test of the abrasion resistance of the shoe material under different conditions.
