Description

A kind of shoe simulation try-on test equipment and its test method

technical field

The application relates to the technical field of shoe performance testing equipment, and in particular to a shoe simulation try-on test equipment and a testing method thereof.

Background technique

In the field of shoe manufacturing, the durability of finished shoes (including bending resistance, wear resistance, and upper pulling resistance) is an important indicator for testing the quality of finished shoes. At present, in the industry, the fatigue test of finished shoes is often achieved by real people trying on them. This method has the problems of long try-on cycle, difficulty in guaranteeing timeliness, and affecting product listing. In addition, there are also differences in test results due to different try-on personnel. big problem.

For this reason, there are industry standards that use testing equipment to test the durability of shoes at home and abroad. However, the existing testing equipment, whether domestic or foreign, has the following shortcomings: 1. It is used for wearing shoes. The shoe last is made of hard PVC material, and its surface is relatively hard, so it cannot form a good bending and extrusion effect, and the simulation effect of human walking or running is not good; Second, in order to achieve bending, the existing The shoe lasts used in the test equipment all need to have large grooves on the foot surface, so the whole shoe last is not full enough and does not have a complete toe part and ankle part. Therefore, during the test, it cannot be used. Accurately simulate the phenomenon of squeezing and pulling on different positions of the upper under the behavior of people walking or running, so it is impossible to accurately obtain the durability test structure of the shoe; 3. When the existing test equipment is tested, the toe cap is often It is suppressed, but the heel of the shoe is free, and the degree of freedom of the shoe corresponding to the forefoot of the human foot is insufficient, so it cannot well reflect the force of the shoe when it is stepped on.

In addition, in the prior art, there are also test equipments that use the structure of mechanical legs to simulate human gait behavior. These test equipments generally have problems such as large size, large floor space, complex structure, high cost and low test effect. In addition, some of these test equipment still have problems such as limited flexibility of mechanical legs, poor gait simulation effect, poor simulation effect of the force of the finished shoe, and large equipment loss. In this device, the forearm and the connecting part of the robot are used to simulate the functional part of the thigh of the human body, the leg support part is used to simulate the functional part of the calf of the human body, and the last is used to simulate the foot of the human body. The two ends of the leg support part are directly connected to the connecting part and the last respectively, and there is no rotating structure for simulating the joint function. Therefore, the whole leg and foot of the robot are always on the same straight line. The gait simulation is completed by rotating around the same fulcrum while the relative posture remains stationary. During the process, when the leg drives the foot to land on the ground, the foot cannot directly complete the action of lifting the heel and pressing the forefoot at the landing point. The upper surface of the shoe can be bent only by gradually moving backward relative to the ground simulation module until the legs are in a vertical state, and then continuing to slide relative to the ground simulation module. When the human body actually walks or runs, the friction effect and the bending effect of the shoes are very different, and the range of activities required for the legs and feet is extremely large (also the reason why the ground simulation module is set to be movable in this patent application), Therefore, the device cannot realistically simulate the state of the shoes stepping on the ground and bending freely when the human body is walking or running, and it cannot achieve the feeling of squeezing and pulling the shoe material when the human foot is moving, so the test results are accurate. In addition, the strength of the mechanical legs in this device is often large when stepping down, so the shoes and lasts have a large load and a low service life. By setting elastic shock absorption in the legs and feet Although the components can play a certain buffering effect, the loss of equipment and materials is still large, and it is difficult to control the production cost and maintenance cost.

With respect to the prior art, the above-mentioned scheme has the following beneficial effects:

1. In this application, the shape of the simulated foot model matches the shape of the human foot, and its shape is full, so it can reliably simulate the situation that the foot is squeezed due to bending during walking or running, so as to effectively The durability of the shoe material can be clearly recognized. In this simulation foot mold, the body part has good bending resistance, which simulates the characteristics of the human foot from the heel part to the metatarsophalangeal joint part, which are supported by the tarsus and metatarsal bones and cannot be bent. , the toe part is made of flexible material, which is connected to the front end of the body part and can be bent relative to the body part, which is used to simulate the toe part of the human foot located on the front side of the metatarsophalangeal joint; when it is necessary to test the fatigue characteristics of the finished shoe When the sock and the shoe to be tested are set on the outer jacket of the simulated foot model, the driving mechanism is turned on, and the simulated foot model and the finished shoe are driven by the driving mechanism to switch continuously from stepping to the treading surface and away from the treading surface, so as to realize the test and the test equipment. The structure is simple, the cost is low, the space is small, and since the drive mechanism only needs to be controlled to reciprocate in a single direction, the test efficiency is extremely high, which can greatly shorten the fatigue test cycle of new products and ensure product launch time; specific The test principle of the present application is that when the simulated foot model and the shoe to be tested move toward the tread surface, since the length direction of the simulated foot model is inclined relative to the tread surface and the toes of the simulated foot model are inclined toward the tread surface, the shoe to be tested corresponds to the simulated foot model. The part of the toe first contacts the tread surface and gradually bends relative to the part corresponding to the body part, so as to realize the bending condition of the finished shoe and the various positions of the upper surface when the heel is lifted relative to the ground and pushed down when walking or running. Simulation of force conditions (bending, compressing, stretching, and squeezing, etc.), and due to real people walking or running, the most significant force in shoes occurs when the heel of the foot is lifted and the toe of the foot is under the part of the foot. When pedaling, that is, when the human foot is bent, the force of the shoe is the most significant. Therefore, in the test equipment of the present application, the simulated foot mold is set to the shape of the toes pointing downwards, so as to directly form the toe pedal when pedaling. And the posture of raising the heel of the main body is enough to achieve the simulation effect and meet the fatigue test requirements of the shoe to be tested due to bending.

When the toes of the simulated foot model move toward the tread surface, the toes will slide forward relative to the tread surface. During this sliding process, the displacement and friction force of the shoe to be tested relative to the tread surface are the same as those of a real person walking or running. The displacement and friction force value formed relative to the ground when the forefoot is pushed down and lifted are similar. Therefore, the test equipment provided by the present application can also simulate the friction between the sole of the shoe and the ground, so it can also realize the sole of the shoe to be tested. Abrasion resistance test.

Another outstanding advantage of the present application is that, since the toe of the simulated foot mold is made of flexible material, it has good bending characteristics and a certain buffering capacity. When the driving mechanism drives the simulated foot mold and the shoe to be tested In the process of stepping down, the toes have a buffering effect on the driving mechanism and the shoes to be tested, which can prevent the driving mechanism and the shoes to be tested from being damaged, and improve the service life of the testing equipment and the testing accuracy of the shoes to be tested.

2. In this application, the angle between the length direction of the simulated foot mold and the tread surface is 0-80°, and the size of the angle between the length direction of the simulated foot mold and the tread surface is determined by the state of human activity (walking or running, etc.), the shoes to be tested. It is determined by factors such as size and style design. For example, the length direction of the simulated foot model corresponding to the shoe simulation try-on test equipment used to simulate human walking and the angle between the tread surface are relative to the length direction of the simulated foot model corresponding to the simulated human running. The included angle with the tread surface should be smaller; the angle between the length direction of the simulated foot model corresponding to the shoe to be tested with a smaller size and the tread surface is compared with the length direction of the simulated foot model corresponding to the shoe with a larger size to be tested. The angle with the tread surface should be smaller; the angle between the length direction and the tread surface of the simulated foot model corresponding to the shoe to be tested with a warped toe part is compared with that of the simulated foot model corresponding to the shoe to be tested with a flat toe part. The angle between the length direction and the tread surface should be small.

3. In this application, the setting of the angle adjustment structure makes the angle of the simulated foot mold relative to the tread surface adjustable, so that the fatigue resistance of the shoes to be tested with different functions, different sizes or different styles can be tested. In addition, It also ensures that the test can be performed based on different bending degrees of the same finished shoe to be tested, so as to obtain the fatigue resistance characteristics of the finished shoe more comprehensively.

4. In this application, the simulated foot mold is detachably fixed to the output end of the drive mechanism, so it can be replaced according to the size of the shoe to be tested, so as to test products of different sizes and shoe types.

5. In this application, the artificial foot mold is composed of a silicone part and a metal holder. The silicone part can be easily molded and simulate the shape of the human foot and the state of the human skin. The metal holder can not only play the role of simulating the bones of the human foot, but also It can be reliably connected with the drive mechanism and ensure that the shape of the silicone part is not damaged.

6. In this application, the foot body is used to open a groove on the bottom surface of the metatarsophalangeal joint part of the corresponding human body, and the setting of the groove locates the bending boundary of the simulated foot mold, thereby determining the bending position of the shoe to be measured, and ensuring the test. accuracy of results.

7. In this application, the width of the groove is 4.5-5.5mm and the depth is 9-11mm, which ensures that the bending boundary can be reliably defined without affecting the fullness of the simulated foot mold.

8. In this application, the surface hardness of the silicone parts is 17A-23A, which has good wear resistance and long service life.

9. In this application, the drive mechanism includes a drive member and an angle adjustment structure, and the drive member can be a screw stepping motor, a linear motor or a magnetic levitation motor, with a simple structure and reliable power supply function; the angle adjustment structure includes a fixed member and a rotating member, The fixed piece constitutes a turntable fixedly connected with the driving end of the driving piece, and the rotating piece can be rotated and positioned relative to the turntable, so as to realize the purpose of adjusting the angle of the simulated foot mold, with simple structure and low cost.

10. In this application, the setting of the controller makes the automation degree of the test equipment higher.

11. In this application, the pressure sensor is configured corresponding to the tread surface and is electrically connected to the controller, and the controller is suitable for controlling the operation of the driving mechanism based on the signal transmitted by the pressure sensor, so as to ensure that the driving mechanism drives the simulated foot model and the shoe to be tested during testing. The pressing force can be matched with the pressing force of the real person to further improve the accuracy of the test results.

12. In this application, the simulated floor can be replaced, that is, the test equipment of this application can simulate different activity environments, such as cement floor, tile floor or plastic floor, etc. Therefore, the shoes to be tested can be based on their real applications. Fatigue tests are performed on scenarios to improve the accuracy of tests.

13. In this application, the cabinet is provided with a climate chamber, and the climate chamber can control the temperature, humidity, wind power, ultraviolet rays and the degree of rain and fog formation through the controller, so that the shoes to be tested can also be subjected to fatigue tests based on different use environments to further Improve test accuracy.

14. In this application, the setting of the operation panel is convenient for testers to control and monitor the test equipment.

15. In the present application, the test steps of the shoe simulation try-on test equipment are simple, and the requirements for the operator's ability are not high, so the labor cost can be controlled, and the test results can be guaranteed to be accurate and effective.

Specifically, as shown in FIG. 5 to FIG. 9 , the simulated foot mold 3 includes a silicone part 31 and a metal holder 32 . The shape of the silicone part 31 matches the human foot, and includes an ankle 311 and a foot body 312 . The metal holder 32 includes a bottom plate 321 and a connecting column 322. The bottom plate 321 is wrapped in the foot body 312 and extends from the heel portion of the foot body 312 to the foot body 312 for corresponding to the metatarsophalangeal joint portion of the human foot. When the body 312 is supported on the ground, it is parallel to the ground, and the front end of the bottom plate 321 is a hypotenuse that gradually slopes backward from the inside of the self-sufficient body 312 toward the outside of the foot body 312 to match the distribution direction of the metatarsophalangeal joint of the human foot. It should be understood that this The front and rear orientations referred to in the embodiment are specifically based on the orientation of the simulated foot model 3 . One end of the connecting column 322 is fixedly connected with the bottom plate 321 , which can be fixed by means of integral molding or screw connection. The part of the silicone part 31 located at the front end of the bottom plate 321 constitutes the toe part 30b, and the remaining part and the metal holder 32 together constitute the body part 30a. The simulation foot mold 3 is supported by a silicone part 31 and a metal holder 32. The silicone part 31 can be easily shaped and simulate the shape of the human foot and the state of the human skin. The metal holder 32 can not only play the role of simulating the bones of the human foot, but also can Reliably connect with the drive mechanism 2 and ensure that the shape of the silicone part 31 is not damaged. Preferably, in this embodiment, the hardness of the surface layer of the silicone part 31 is 17A-23A, and its wear resistance is good, which is beneficial to ensure the service life.

The specific way of fixing the simulated foot mold 3 and the output end of the driving mechanism 2 provided in this embodiment is as follows: the heel and the ankle 311 of the simulated foot mold 3 are partially inserted between the first plate 2222a and the second plate 2222b. Specifically, The bottom surface of the heel portion of the foot body 312 is in contact with the second plate 2222b, and the top end of the connecting column 322 is in contact with the first plate 2222a. After the abutment is in place, the connecting column 322 and the first plate 2222a are fixed by bolts. The installation of the simulation foot mold 3 is relatively simple and easy to operate. As shown in FIG. 4 , the second plate 2222b is always inclined and extended in this embodiment. Therefore, after the simulation foot mold 3 is installed in place, its length direction is relatively The tread surface 121 is at an angle and the toes of the dummy foot model 3 face the tread surface 121 . Thus, when the dummy foot model 3 steps down to the tread surface 121 , the toe portion 30 b of the dummy foot form 3 will inevitably contact the tread surface 121 first and face the body portion 30 a Since the body portion 30a has the ability to resist bending, the body portion 30a is always inclined downward along its length direction, thereby simulating the bending state of the human foot when walking or running. And based on the installation method of the simulation foot mold 3 on the mounting frame 2222, it can be known that the connection relationship between the simulation foot mold 3 and the output end of the drive mechanism 2 is a detachable fixed relationship, which also makes the simulation foot mold 3 can be easily replaced according to actual needs. Therefore, in this embodiment, the simulated foot mold 3 is suitable to be replaced according to the size and shape of the finished shoe to be tested, so as to meet the requirements for fitting shoes of different sizes and different shoe shapes and to complete the fatigue test.

In this embodiment, the shape of the simulated foot mold 3 matches the shape of the human foot, and its shape is full, so it can reliably simulate the situation that the foot squeezes the finished shoe due to bending during walking or running, so as to effectively The durability of the shoe material is clearly recognized. In the simulated foot mold 3, the body portion 30a has good bending resistance, which simulates the support of the tarsus and metatarsal bones in the heel part to the metatarsophalangeal joint part of the human foot and cannot be bent. The toe portion 30b is made of flexible material, which is connected to the front end of the body portion 30a and can be bent relative to the body portion 30a, which is used to simulate the toe portion 30b of the human foot on the front side of the metatarsophalangeal joint; when When it is necessary to test the fatigue characteristics of the finished shoes, put socks and the finished shoes to be tested on the outer jacket of the simulated foot model 3, open the driving mechanism 2, and drive the simulated foot model 3 and the finished shoes through the driving mechanism 2 from stepping to the tread surface 121 and from the tread surface 121. The test equipment is continuously switched in the state of being far away to realize the test. The test equipment has a simple structure, low cost and small space occupation. Since it only needs to control the reciprocating motion of the driving mechanism 2 in a single direction, the test efficiency is extremely high, which can greatly shorten the time required for testing. The fatigue test cycle of the product ensures the time to market of the product; specifically, the test principle of the shoe simulation try-on test equipment is that when the simulated foot mold 3 and the shoe to be tested move towards the tread surface 121, the length direction of the simulated foot mold 3 It is inclined relative to the tread surface 121 and its toes are facing the tread surface 121. Therefore, the part of the shoe to be tested that corresponds to the toe portion 30b of the simulated foot mold 3 first contacts the tread surface 121 and gradually bends relative to the portion corresponding to the body portion 30a to achieve Simulation of the bending situation of the shoe and the force situation (bending, compression, stretching and extrusion, etc.) of each position of the shoe upper surface when the heel is lifted relative to the ground and pushed down when a real person walks or runs. When a real person is walking or running, the force on the shoe is most significant when the heel of the foot is lifted and the toe 30b of the foot is pushed down, that is, when the human foot is bent, the force on the shoe is the most significant. , in the test equipment of the present application, the simulation foot mold 3 is set to the shape of the toes pointing downward, so as to directly form the posture of the toe part 30b and the heel of the body part 30a being lifted when stepping, which is enough to achieve the simulation effect and meet the needs to be tested. Fatigue test requirements for finished shoes due to bending.

During the movement of the toe portion 30b of the simulated foot mold 3 toward the tread surface 121, the toe portion 30b will slide forward relative to the tread surface 121. During this sliding process, the displacement and friction formed by the shoe to be measured relative to the tread surface 121 The force is similar to the displacement and friction force value formed relative to the ground when a real person lifts the forefoot down after stepping down during walking or running. Therefore, the test equipment provided in this application can also simulate the friction between the sole of the shoe and the ground. It can realize the test of the abrasion resistance of the sole of the shoe to be tested.

In addition, another outstanding advantage of this embodiment is that, since the toe portion 30b of the simulated foot mold 3 is made of a flexible material, it has good bending characteristics and a certain buffering capacity. Therefore, when the driving mechanism 2 In the process of driving the simulated foot mold 3 and the shoe to be tested, the toe portion 30b can form a buffering effect on the driving mechanism 2 and the shoe to be tested, so as to prevent the driving mechanism 2 and the shoe to be tested from being damaged and improve the performance of the testing equipment. Service life and test accuracy of the shoe to be tested.

In this embodiment, the angle between the length direction of the simulated foot mold 3 and the tread surface 121 is 0-80°, and the angle is determined by factors such as the state of human activity (walking or running, etc.), the size and style of the shoes to be tested, and so on. For example, the shoe simulation try-on test equipment is used to simulate the length direction of the corresponding simulated foot model 3 when the human body is walking and the angle between the tread surface 121 and the length direction of the corresponding simulated foot model 3 when the human body is running. The included angle should be small; the included angle between the length direction of the simulated foot mold 3 corresponding to the shoe to be tested with a smaller size and the angle between the tread surface 121 is compared with the length direction of the simulated foot mold 3 corresponding to the shoe with a larger size to be tested. The included angle of the treading surface 121 should be small; the angle between the length direction of the simulated foot mold 3 corresponding to the shoe to be tested with the toe part is relatively warped and the angle between the treading surface 121 is compared with the simulation corresponding to the shoe to be tested with the flat toe part. The angle between the length direction of the foot mold 3 and the tread surface 121 is small. In this embodiment, the simulated foot mold 3 can be easily adjusted in angle through the angle adjustment structure 22. Therefore, the fatigue testing equipment provided in this embodiment can realize different functions, different sizes or different styles of shoes to be tested. The fatigue resistance is tested, and at the same time, different bending degrees can be tested based on the same shoe to be tested, so as to obtain the fatigue resistance of the shoe more comprehensively.

The distance between the outer end of the body 312 and the heel of the foot body 312 is 62-64% of the total length of the foot body 312. 71-73% of the total length, the center line of the groove 3121 referred to here is specifically the line centered on the groove 3121 along the groove width direction of the groove 3121. The groove 3121 under this design is located on the inner side of the foot body 312. The distance between one end and the heel of the foot body 312 is greater than the distance between the end located outside the foot body 312 and the heel of the foot body 312, so the groove 3121 gradually slopes backward from the inner side of the foot body 312 toward the outer side of the foot body 312, which simulates The distribution direction of the metatarsophalangeal joints corresponding to the human foot, so it is possible to locate the bending boundary of the simulated foot mold 3, so as to clarify the bending position of the shoe to be tested and ensure the accuracy of the test results. The width of the groove 3121 is 4.5-5.5mm and the depth is 9-11mm, which ensures that the bending boundary can be reliably defined without affecting the fullness of the simulated foot mold 3 .
