Generally, a special sole puncture resistance detector is required for the detection.

Detailed implementation

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Refer to Figures 1 to 7 As shown, to achieve the above object, the present invention provides the following technical solutions: A sole puncture simulation device includes a controller 1, a workbench 2, a mounting bracket 3, a first force-applying assembly 4, a second force-applying assembly 5, and a third force-applying assembly 6. A puncture area 21 is provided on the workbench 2, and a puncture needle device 7 is provided in the puncture area 21; The mounting bracket 3 is installed on the workbench 2. A connecting head 31 and a rotating assembly 32 are provided on the mounting bracket 3. The first force-applying assembly 4, the second force-applying assembly 5, and the third force-applying assembly 6 are all installed on the connecting head 31. The rotating assembly 32 is used to adjust the orientations of the first force-applying assembly 4, the second force-applying assembly 5, and the third force-applying assembly 6; The first force-applying assembly 4, the second force-applying assembly 5, and the third force-applying assembly 6 each include a connecting frame 41, a clamping head 42, and a driving member 43. One end of each connecting frame 41 is connected to the connecting head 31. Each driving member 43 is respectively installed on the corresponding connecting frame 41. The clamping head 42 is installed at the working end of the driving member 43. The driving member 43 is used to drive the clamping head 42 to move up and down; As Figure 2 shown, the driving member 43 is arranged in a driving cylinder structure and can provide a stable driving force.

[0022] The first force-applying assembly 4 is used to clamp and drive the forefoot area; The second force-applying assembly 5 is used to clamp and drive the arch area; The third force-applying component 6 is used to clamp and drive the heel area.

[0023] In the design of the present invention, the forefoot area, the arch area, and the heel area of the shoe sole are respectively clamped by three clamping heads 42, and the orientations of the first force-applying component 4, the second force-applying component 5, and the third force-applying component 6 are adjusted through the rotating component 32 to simulate different road conditions. For example: when on flat ground, the insole is parallel to the ground plane; when there is a steep slope, the insole has a certain inclination with respect to the ground plane.

[0024] Furthermore, by adjusting the angles of the first force-applying component 4, the second force-applying component 5, and the third force-applying component 6, the inclination angle of the insole can be adjusted, thereby simulating different motion states, such as whether the forefoot touches the ground first or the heel touches the ground first, or the forefoot and the heel touch the ground simultaneously. Finally, through the force application situations of the first force-applying component 4, the second force-applying component 5, and the third force-applying component 6, the exercise intensity and the force-bearing situation when the insole contacts the puncture needle device 7 are simulated, so as to achieve the desired quality inspection effect.

[0025] This device can simulate puncture detection under various scenarios and various motion modes.

[0026] The present invention is further configured as: the rotating component 32 includes an adjusting base 33 and an adjusting motor 34, and the connecting head 31 is rotatably connected to the adjusting base 33. With this structural design, the adjusting motor 34 can drive the adjusting base 33 to rotate, thereby realizing the angular change of the adjusting base 33.

[0027] The transmission between the adjusting motor 34 and the adjusting base 33 is achieved through a rotating shaft and some linkage gears. Since it is a conventional technical means and there are various arrangement methods, it will not be elaborated here.

[0028] The present invention is further configured as: an adjusting box 431, an adjusting wheel 432, and a rotating motor 433 are provided on the driving member 43. The adjusting box 431 is fixedly installed at the working end of the driving member 43. Both the rotating motor 433 and the adjusting wheel 432 are installed in the adjusting box 431. One end of the connecting frame 41 is connected to the adjusting wheel 432, and the rotating motor 433 is used to drive the adjusting wheel 432 to rotate.

[0029] With this structural design, the rotating motor 433 drives the adjusting wheel 432 to rotate, so that the connecting frame 41 connected to the adjusting wheel 432 rotates, thereby realizing the angle adjustment of the force-applying component. As Figure 2 shown, a through groove 22 for the moving frame to pass through is opened at the lower end of the adjusting box 431.

[0030] The present invention is further configured that: the three groups of adjusting wheels 432 are respectively a first wheel body, a second wheel body, and a third wheel body. A first limiting rod is provided on the first wheel body. A first limiting groove is penetrated through the second wheel body. A second limiting groove is provided on the third wheel body. The groove lengths of the first limiting groove and the second limiting groove are the same. One end of the first limiting rod passes through the adjusting box 431 and the first limiting groove, and is slidably connected in the second limiting groove.

[0031] Figure 4 As shown, due to the design of the first limiting rod, when the first wheel body, the second wheel body, or the third wheel body rotates, the positional relationship between the first limiting rod and the first limiting groove, and between the first limiting rod and the second limiting groove will change.

[0032] Furthermore, it can avoid excessive torsion among the forefoot area, the arch area, and the heel area of the sole, which affects the elastic performance of the sole itself and causes abnormal puncture effects.

[0033] The present invention is further configured that: the puncture needle device 7 includes a moving component 71, a mounting component 72, and a puncture needle body 73. There are multiple groups of the mounting component 72 and the puncture needle body 73, and they are arranged in one-to-one correspondence. Multiple groups of the mounting components 72 are equidistantly mounted on the moving component 71; A through groove 22 for the puncture needle body 73 to pass through is provided in the puncture area 21.

[0034] Due to the design of this structure, different sizes and types of puncture needles can be installed on different mounting components 72, and the position of the mounting component 72 is adjusted through the moving component 71, so as to quickly realize puncture simulations at different positions and different puncture types.

[0035] The present invention is further configured that: the moving component 71 includes a transmission chain 712, transmission wheels 713, a driving motor 714, and a balancing component 715. The balancing component 715 is provided at both ends of the transmission chain 712; There are two groups of the transmission wheels 713. The transmission chain 712 is wound around the two transmission wheels 713. The driving motor 714 is used to drive one of the transmission wheels 713 to rotate; The mounting component 72 is mounted on the transmission chain 712. When the mounting component 72 moves to the position of the balancing component 715, the orientation of the puncture needle body 73 can be kept unchanged.

[0036] As Figure 5 、 Figure 6 and Figure 7 shown, when the mounting component 72 moves through the position of the balancing component 715, under the action of the balancing component 715, the orientation of the mounting component 72 does not change, so that the initial mounting orientation and mounting angle of the puncture needle remain unchanged to meet the puncture requirements.

[0037] The present invention is further configured such that: the mounting assembly 72 includes a rotating block 721, a guiding block 722, and a mounting block 723. The guiding block 722 and the mounting block 723 are respectively disposed on both sides of the rotating block 721, and the guiding block 722 is used to cooperate with the balancing assembly 715.

[0038] The present invention is further configured such that: the guiding block 722 includes a plurality of guiding columns; The balancing assembly 715 includes multiple groups of balancing plates 8, and a balancing gap 81 for the guiding columns to pass through is formed between the balancing plates 8.

[0039] As Figure 6 and Figure 7 shown, in the design of this structure, when the guiding block 722 moves to both ends of the moving chain, the guiding columns pass through the balancing gap 81 and abut against the balancing plates 8, so that the orientations of the rotating block 721 and the mounting block 723 change. Since the arc of the balancing gap 81 is the same as the arc of the transmission chains 712 at both ends, the orientation of the mounting block 723 remains unchanged all the time, and the orientation of the puncture needle body 73 does not change.

[0040] The present invention is further configured such that: the mounting block 723 includes a mounting base 9 and a connecting seat 91. The mounting base 9 is connected to one side of the rotating block 721, the connecting seat 91 is detachably mounted on the mounting base 9, and the puncture needle body 73 is detachably mounted on the connecting seat 91. In the design of this structure, different connecting seats 91 can be installed to meet the installation of different puncture needle bodies 73. Further, according to the different-angle notches provided on the connecting seat 91, the puncture needle body 73 can be installed at different angles with the ground plane when installed, so as to simulate various puncture situations in reality.

[0041] The present invention is further configured such that: a abutting portion 23 is provided below the through slot 22 corresponding to the workbench 2. A return spring is provided inside the mounting base 9, and the lower end of the connecting seat 91 abuts against the return spring. When the insole is pressed down, the connecting seat 91 abuts against the abutting portion 23.

[0042] As Figure 7 shown, in the design of this structure, during the puncture simulation, the pressure of the connecting seat 91 can act on the abutting portion 23, reducing the influence on the rotating block 721 and the transmission chain 712, thereby playing a certain protective role for the device.

[0043] As Figure 1 and Figure 5 shown, an operation port is provided on the side of the workbench 2 for the operator to replace the puncture needle body 73. Taking the operation port and the through slot 22 as the two working positions of the puncture needle, corresponding to Figure 5 the left and right sides of the transmission chain 712 in

[0044] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
