The current test standard GB / T 3903.3-2011 "Shoe Test Method for Peeling Strength" can objectively detect the adhesion of the shoe head, but it cannot deeply judge the quality problems of the shoe head that may occur during wearing, nor can it evaluate the protection effect of the shoe head.

It can also be adjusted according to the structure and shape of different shoes, and has a wide range of applications. However, due to the different weights of different shoes, the impact force on the shoe head cannot be controlled every time; the protection effect of the shoe head on the foot when impacted cannot be given; the calf column is used to support the shoe opening position to fix the shoe during impact, which is easy to loosen; the middle part of the shoe is used to support the support plate to simulate the foot arch, which does not match the actual wearing state of the foot, and the other parts of the shoe are not effectively supported during the test; the sample may move during the test, affecting the test effect.

[0030] 6. Shock absorbers. Detailed Implementation

[0031] like Figures 1-3 As shown, the shoe toe impact resistance protection performance testing device disclosed in this embodiment includes a base plate 1, a housing 2, a drive assembly 3, a foot mold 4, and an impact assembly 5. The housing 2 is located on top of the base plate 1. The drive assembly 3 includes a drive mechanism 31 located on the upper side of the housing 2 and a swing arm 32 connected to the output end of the drive mechanism 31. The foot mold 4 is located at the end of the swing arm 32 away from the drive mechanism 31, and a first force sensor is located at the front end of the foot mold 4. The impact assembly 5 is located on top of the base plate 1, and the foot mold 4 impacts the impact surface of the impact assembly 5 under the drive of the swing arm 32.

[0032] In practical use, the test shoe is first put on the foot mold 4. Then, the drive mechanism 31 drives the swing arm 32 to rotate until it is parallel to the base plate 1. When the swing arm 32 rotates, it drives the foot mold 4, which is wearing the test shoe, to rotate to a horizontal test height. Then, the transmission action between the drive mechanism 31 and the swing arm 32 is disconnected, allowing the swing arm 32 to drive the foot mold 4 to rotate freely downwards and impact the impact surface of the impact component 5. After the impact, the first force sensor feeds back the impact force from the toe of the test shoe to the shoe mold. By fitting the foot mold 4 to the test shoe, the test is more in line with the human foot, and the impact force feedback is more accurate. It can highly simulate the actual impact of different people wearing shoes on the toe, and can quantitatively evaluate the impact resistance and protective performance of the toe.

[0033] Specifically, in the embodiment, the foot mold 4 is detachably connected with the swing arm 32, and the foot mold 4 includes a series of different sizes, so as to replace the foot mold matched with the shoe when testing the shoe of different sizes, and the practicability is higher. The foot mold 4 is made of soft material to better simulate the actual situation that the toe of the shoe is impacted when the foot is worn, and the front end of the foot mold 4 is designed to be toe-shaped, or at least the thumb of the foot is designed separately. The first force value sensor or other energy testing device is arranged at the thumb of the foot mold 4, so as to detect the impact force or impact energy of the toe of the shoe fed back to the foot each time. The counterweight device is arranged on the swing arm 32, and the total weight of the swing system composed of the shoe, the foot mold 4 and the swing arm 32 is adjusted through the counterweight device, so as to control the consistency of the impact energy when the sample of different weights is impacted. Exemplarily, the counterweight device can be a weight, and the connecting part for connecting the weight is arranged on the swing arm 32. The connecting part can be connected with the weight through threads or buckled, so as to facilitate disassembly and assembly. Through the foot mold 4 and the counterweight device, the shoe of different weights can be impacted to the impact interface with the same fixed impact energy each time, and the impact energy can be adjusted, so that the flexibility, accuracy and stability of the measurement are greatly improved.

[0034] In addition, the bottom plate 1 is arranged in a rectangular shape, is mainly made of metal or alloy material, has higher weight, and can ensure that the bottom plate 1 does not slide during the test, so as to improve the stability of the test.

[0036] Preferably, the driving mechanism 31 further includes an induction sensor 313 arranged on the side surface of the fixed disc 311, and the induction sensor 313 is used for sensing the swing arm 32. The induction sensor 313 can sense whether the swing arm 32 moves to the highest horizontal position. If the swing arm 32 moves to the highest horizontal position, the controller receives the signal of the induction sensor 313, and then controls the motor to stop outputting, and the swing arm 32 is disconnected. Subsequently, the swing arm 32 makes free fall motion to impact the impact interface.

After the angle is adjusted, the first threaded sleeve 5432 is rotated by the first rotating handle 5433 to make the first threaded sleeve 5432 close to the vertical plate 541, so that the sliding plate 5425 and the semicircular plate 5423 are locked, and the angle is locked.

The mounting seat 51 can move left and right along the bottom plate 1 to adjust the distance between the impact interface 52 and the test shoe, so as to adapt to the test of different sizes of shoes.

[0042] Preferably, the positioning mechanism 512 comprises a locking screw 5121, a locking sliding block 5122, a second threaded sleeve 5123 and a second rotating handle 5124. The locking screw 5121 extends from the top of the mounting seat 51 to the bottom of the bottom plate 1 through the second sliding groove 11 and is threadedly connected with the locking sliding block 5122.
