Therefore, the quality of footwear products is closely related to their folding resistance. When people wear and use shoes, the part of the shoes that bends the most is the front part of the shoes. For this reason, a folding resistance test device for footwear products is designed in the prior art. This folding resistance test device for footwear products mainly includes a fixed pedal and a whole swing pedal located in front of the fixed pedal. The middle and rear parts of the shoe to be tested are fixed on the fixed pedal, and the front part of the shoe is supported on the swing pedal. Then, the whole swing pedal is driven by a first motor to swing continuously to repeatedly bend the shoe. After a certain number of bends, the sole is checked to see if there are any breakages, cracks, or debonding. This test is to test the bending and folding resistance of the shoe under normal wearing conditions. The folding resistance test device in the prior art has only one whole swing pedal. The entire front of the shoe is completely supported on this swing pedal and moves synchronously as a whole under the pressure of the entire swing pedal.

[0014] The beneficial effects of the folding resistance test device for footwear provided by the present invention are: Compared with the prior art, in the folding resistance test device for footwear provided by the present invention, the pedal group includes at least three swing pedals arranged at intervals along the width direction of the fixed pedal, and the driving mechanism can independently drive each swing pedal to swing around the hinge axis.

[0021] See also Figures 1 to 8 The present invention provides a folding resistance test device for footwear products, wherein the folding resistance test device for footwear products comprises: A base 100 (specifically, a support seat, a support frame, a support shell and other structures), a fixed pedal 1 and a pedal group located in front of the fixed pedal 1 in the length direction, the pedal group includes at least three swing pedals 2 arranged at intervals along the width direction of the fixed pedal 1, the fixed pedal 1 is fixedly connected to the base 100, each swing pedal 2 is hinged to the base 100 along the same hinge axis, and the hinge axis of the swing pedal 2 extends along the width direction of the fixed pedal 1; A driving mechanism disposed on the base 100, the driving mechanism can independently drive each swing pedal 2 to swing around the hinge axis; The fixing mechanism is movably arranged on the base 100 and is used to fix the shoe to be tested on the fixed pedal 1.

[0022] Since in the folding resistance test device for footwear products provided by the present invention, the pedal group includes at least three swing pedals 2 arranged at intervals along the width direction of the fixed pedal 1, and the driving mechanism can independently drive each swing pedal 2 to swing around the hinge axis, the folding resistance test device for footwear products can test the folding resistance of the shoe in a more refined manner by means of local force bending, compared with the traditional folding resistance test device in which a whole swing pedal is used to repeatedly bend the shoe. For example, when only the middle swing pedal 2 among at least three swing pedals 2 is moved to apply force to bend the front part of the shoe, the effect of force bending at a local point in the middle of the front part of the shoe can be simulated; and when only the swing pedals 2 on both sides of at least three swing pedals 2 are moved to apply force to bend the shoe, the shoe folding resistance can be tested in a more refined manner by means of local force bending. When folding the front of the shoe, the influence of the bending of the local points on both sides of the front edge of the shoe under force can be simulated, so as to finely bend the front of the shoe by locally applying force. This is very beneficial for the refined research on the folding resistance analysis of footwear products, because the shoes in actual use are often not bent like a whole swing pedal due to the complexity of environmental road conditions and the particularity of human foot structure. Therefore, the refined research on the folding resistance analysis of footwear products can simulate the bending of the local points on the front of the shoe under force, and analyze the different influences on the shoe damage under different force conditions, so as to design shoes with better quality and stronger targeting (for example, only local reinforcement of parts that are more prone to damage)

[0023] According to one embodiment of the present application, the driving mechanism independently drives each swing pedal 2 to swing around the hinge axis, including: driving each swing pedal 2 to swing synchronously in the same direction at a constant angular velocity around the hinge axis so that the whole formed by each swing pedal 2 drives the shoe to bend (similar to the situation where a whole swing pedal bends the shoe) to simulate the situation where the front part of the shoe is bent as a whole on a flat surface; driving each swing pedal 2 to swing synchronously in the same direction with different swing amplitudes around the hinge axis so that the front part of the shoe has bending and extrusion with different swing amplitudes at multiple positions along the width direction of the shoe to simulate the situation where the front part of the shoe is bent as a whole on an uneven surface; and driving part of the swing pedals 2 in each swing pedal 2 to swing around the hinge axis, which also means that this part of the swing pedal 2 does not swing (move), thereby simulating the situation where the front part of the shoe is locally bent under force.

[0024] In addition, the folding resistance test device for footwear provided by the present invention can also be equipped with another fixed pedal 1, and the other fixed pedal 1 is equipped with an integral swing plate 3. The integral swing plate 3 is hinged to the base 100, so that the bending properties of the shoes to be tested can be tested in a traditional mode. The integral swing plate 3 can be driven by the driving mechanism provided by the present invention to achieve reciprocating swing, and can also be driven by a swing motor 22 to achieve reciprocating swing.

[0025] According to a specific embodiment of the present application, the base 100 includes an upper support plate 101 connected to a fixed pedal 1 away from the pedal group and another fixed pedal 1 away from the overall swing plate 3. Each fixed pedal 1 is provided with a matching fixing mechanism, and the fixing mechanism includes a vertical electric guide rail 4 extending in the vertical direction arranged on the upper support plate 101, a horizontal electric guide rail 5 extending in the horizontal direction connected to the vertical electric guide rail 4, and a shoe pressing rod 6 connected to the horizontal electric guide rail 5. A shoe pressing block 7 is provided at the lower end of the shoe pressing rod 6. In addition, a pushing cylinder 8 is also provided on the upper support plate 101. The piston rod of the pushing cylinder 8 is provided with an arc-shaped push plate 9 located above the fixed pedal 1. The inner concave surface of the arc-shaped push plate 9 is used to abut against the tail end of the shoe to be tested.

[0026] According to one embodiment of the present application, the fixed pedal 1 is fixedly connected to the base 100 in the horizontal direction, the end of the swing pedal 2 adjacent to the fixed pedal 1 is hinged to the base 100, and the lower surface of the end of the swing pedal 2 away from the fixed pedal 1 is detachably supported on the base 100; The folding test device includes an inclined guide rail 10, and the driving mechanism includes a power output member 11, a slider 12 and a top support member. The inclined guide rail 10 is located below the fixed pedal 1 and the pedal group and gradually extends upward along the arrangement direction of the fixed pedal 1 and the pedal group. The base 100 also includes an inclined support plate 102. The inclined guide rail 10 can be specifically set on the inclined support plate 102, and the slider 12 can be slidably set on the inclined guide rail 10. The power output member 11 is transmission-connected with the slider 12 to be able to drive the slider 12 to slide back and forth along the inclined guide rail 10. The top support member can be optionally installed on the slider 12. When the slider 12 is equipped with a top support member, when the power output member 11 drives the slider 12 to slide back and forth along the inclined guide rail 10, the top support member repeatedly supports the pedal group to enable each swing pedal 2 to swing independently around the hinge axis.

[0027] According to one embodiment of the present application, the slider 12 is a triangular structure, the upper surface of the slider 12 is a horizontal plane, and the upper surface of the slider 12 never contacts the swing pedals 2 when the slider 12 slides back and forth along the inclined guide rail 10. The slider 12 has at least three mounting holes 121 passing through its upper surface, and the number and positions of the mounting holes 121 correspond to the at least three swing pedals 2. The supporting member includes at least three top columns 13, and the upper end of the top column 13 preferably has an arc-shaped head 131 for supporting the swing pedal 2. Among the at least three top columns 13, there are top columns 13 with the same height and top columns 13 with different heights. Each top column 13 can be inserted in the mounting hole 121, and at least three top columns 13 preferably have There are multiple model groups of top columns 13, and each model group of top columns matches the number of mounting holes 121 and has the same number of at least 3 top columns 13. After the top column 13 of the same size is inserted into each mounting hole 121, it matches the above-mentioned "driving each swing pedal 2 to swing synchronously in the same direction at a constant angular velocity around the hinge axis". After the top columns 13 of different sizes are inserted into the mounting holes 121, it matches the above-mentioned "driving each swing pedal 2 to swing synchronously in the same direction at different swing amplitudes around the hinge axis". Some mounting holes 121 are inserted with top columns 13, and some mounting holes 121 are not inserted with top columns 13, which matches the above-mentioned "driving some of the swing pedals 2 to swing around the hinge axis".

[0028] According to one embodiment of the present application, the mounting hole 121 is adjacent to the front end of the slider 12, and the arrangement direction of the rear end and the front end of the slider 12 is consistent with the arrangement direction of the fixed pedal 1 and the pedal group. The mounting hole 121 also penetrates downwardly through the lower surface of the slider 12, and the number of inclined guide rails 10 is consistent with the number of mounting holes 121, and the inclined guide rails 10 are aligned with the lower ends of each mounting hole 121 one by one. The inclined guide rail 10 is a magnetic guide rail, and the lower end of the top column 13 is a magnetic end. The magnetic end also forms a downwardly opening limit groove 132. When the top column 13 is inserted into the mounting hole 121, the magnetic end of the top column 13 is aligned with the corresponding inclined guide rail. The inclined guide rail 10 is magnetically engaged, and the magnetic end of the top column 13 limits the corresponding inclined guide rail 10 in the limiting groove 132. In order to make the swing amplitude of the swing pedal 2 meet certain requirements, such as as large as possible, the mounting hole 121 needs to be as close to the front end of the slider 12 as possible, and the corresponding inserted column can also be as close to the front end of the slider 12 as possible. Since the front end of the slider 12 gradually narrows, the advantage of this embodiment is that the lower end of the top column 13 is magnetically engaged with the corresponding inclined guide rail 10, and further limited by the limiting groove 132, the stability of the top column 13 when inserted in the corresponding mounting hole 121 is greatly improved.

[0029] See also Figure 2 , Figure 5 and Figure 6 In addition, the fixed pedal 1 is formed with top column through holes 14 corresponding to the number and position of at least three mounting holes 121, so that the top column 13 can pass downward through the corresponding top column through holes 14 to reach the mounting holes 121 of the slider 12.

[0030] According to a preferred embodiment of the present application, the power output member 11 is a first motor, and the driving mechanism further includes a turntable 15, a driving rod 16, a sleeve 17 and a guide rod 18. The output shaft of the first motor (power output member 11) is connected to the turntable 15 in a transmission manner, and the turntable 15 is rotatably connected to the base 100 through a rotating shaft coaxial with its central axis. Preferably, the output shaft of the first motor is connected to the turntable 15 through a gearbox 23, so that the rotation speed of the turntable 15 can be adjusted as needed. The guide rod 18 is arranged on one side of the turntable 15, and the axial direction of the guide rod 18 is arranged along the radial direction of the turntable 15. The sleeve 17 can be movably and lockably mounted on the guide rod 18 along the axial direction of the guide rod 18, and the driving rod 16 can be locked and mounted on the guide rod 18. One end of the driving rod 16 is hinged to the sliding sleeve 17 through the first hinge shaft 19, and the other end of the driving rod 16 is hinged to the slider 12 through the second hinge shaft 20. The first hinge shaft 19 and the second hinge are parallel to the central axis of the turntable 15. The sliding sleeve 17 can be axially moved by manual operation and manually mechanically locked to the guide rod 18 by a locking screw, etc., or it can be automatically moved and locked axially by electric control. When the sliding sleeve 17 is locked at different axial positions of the guide rod 18, the rotation radius of the first hinge shaft 19 rotating with the turntable 15 is different, so that the reciprocating movement distance of the slider 12 can be adjusted, and then the swing amplitude of the swing pedal 2 can be adjusted, thereby adjusting the bending test amplitude of the shoe to be tested.

[0031] According to a preferred embodiment of the present application, an external thread is formed on the outer periphery of the guide rod 18, an internal thread that is threadedly matched with the external thread is formed on the inner side of the sleeve 17, and a second motor 21 is connected to the axial end of the guide rod 18, that is, in this embodiment, the sleeve 17 realizes automatic axial movement and locking to the guide rod 18 through electronic control.

[0032] According to a preferred embodiment of the present application, the pedal group includes five swing pedals 2, each of which has the same size. The folding test device has different models corresponding to shoes of different sizes. When the shoes to be tested are supported on the fixed pedal 1 and five swing pedals 2 of the corresponding model of the folding test device, the vertical projections of the five swing pedals 2 can all pass through the shoes to be tested. The advantage of the preferred situation of five swing pedals 2 is that it can simulate as much as possible (not representing that it can completely simulate) the situation in which the five toes on the wearer's feet work together with the ground to bend the shoes, which is more conducive to simulating and exploring the bending situation of the shoes under real conditions.
