[0015] From the above description of the present application, the present application has the following beneficial effects relative to the prior art:

[0016] 1. By setting the forefoot pressing head assembly and the heel pressing head assembly, the second driving piece drives the second pressing head to abut against the upper surface of the heel area of the shoe sole, and the first driving piece drives the first pressing head to reciprocate in the direction perpendicular to the test table surface so that the first pressing head abuts against the forefoot area of the shoe sole and then separates from the abutment. The forefoot and the heel are linked, and the data of the rebound force measured by the first measuring device and the second measuring device can know the rebound condition of the forefoot area of the shoe sole in the landing process, and can also know the rebound condition of the heel in the landing process, and further know the boosting effect of the shoe sole on the foot in the process that the forefoot lands and the heel lifts.

[0017] 2. The first measuring device adds a timing sensor, measures the time of the process that the first pressing head abuts against the forefoot area of the shoe sole and then separates from the abutment, and combines the time and the rebound force, so as to know the rebound force change in different time periods, which is helpful for analyzing the rebound condition of the shoe sole.

[0018] 3. The heel pressure head assembly slides back and forth on the frame parallel to the extension direction of the sole. It can adjust the position of the heel pressure head assembly according to different sole sizes, so that the forefoot area and heel area of ​​different shoe sizes can correspond to the first and second pressure heads, which is convenient for detecting soles of different sizes.

[0019] 4. The heel indenter assembly slides along the first slide rail on the test platform via a sliding groove. When the position of the heel indenter assembly needs to be adjusted, adjust the locking mechanism to move it away from the first slide rail. When the position of the heel indenter assembly is adjusted to the correct position, adjust the locking mechanism to press it against the first slide rail, thus positioning the heel indenter assembly on the first slide rail and preventing it from moving relative to the first slide rail.

[0020] 5. The projection of the first slide rail onto a plane perpendicular to the test platform and perpendicular to the extension direction of the first slide rail is T-shaped, so that when it slides with the slide groove, the slide groove cannot disengage from the first slide rail in a direction perpendicular to the test platform.

[0021] 6. The lifting component is driven by the third drive component to move back and forth in a direction perpendicular to the test platform, which can adjust the height of the forefoot pressure head component to adapt to different sole thicknesses.

[0022] 7. Since the locking handwheel is limited in the direction of the first axis, rotating the rotating part causes the second clamping part to move closer to or further away from the first clamping part. When the lifting rod is in position, rotating the locking handwheel causes the second clamping part to approach the first clamping part and abut against the outer wall of the lifting rod, thus clamping the lifting rod together and making its positioning more stable. When it is necessary to adjust the lifting rod, rotating the locking handwheel causes the first clamping part to move away from the first clamping part and disengage from abutting against the outer wall of the lifting rod, releasing the lifting rod and allowing its height to be adjusted.

[0023] 8. A lubrication system is provided to supply lubricant to the forefoot pressure head assembly, heel pressure head assembly, and lifting mechanism, reducing friction and wear.

[0024] 9. During the stamping process, the forefoot press head assembly may cause the equipment to shake. Adding a cylinder, ensuring it always exerts an upward force, and using a dual-unit assembly to adjust the magnitude of this upward force, balances the weight of the moving parts of the forefoot press head assembly, making the upward and downward forces roughly equal. This results in smoother equipment operation and reduced shaking.

[0025] 10. After the second pressure head touches the upper surface of the heel area of ​​the sole, the first drive component is controlled to drive the first pressure head to press against the forefoot area of ​​the sole and move away from it. The rebound force of the forefoot area of ​​the sole is measured by the first measuring device, and the rebound condition of the forefoot area can be determined from the measured data. During the process of the first pressure head pressing against the forefoot area of ​​the sole and moving away from it, the rebound force of the heel area of ​​the sole is measured by the second measuring device, and the rebound condition of the heel area can be determined from the measured data. This test can link the forefoot and heel, and by analyzing the measured data, the effect of the sole on the foot assistance during the forefoot landing and heel lift process can be determined.

[0042] As shown in the drawings, Figure 1 , 4 , 5 and 7, the rack 1 is provided with a rack body 11, a lifting mechanism 12 and a test table 13 for placing the shoe sole. As shown in the drawings, Figure 1 and 2 , the rack body 11 is provided with an upper chamber 111 and a lower chamber 112 formed by a plate material, and the upper chamber 111 is located above the lower chamber 112. The first window 1111 is arranged on the cavity wall of the front surface of the upper chamber 111. In this embodiment, the front surface refers to the surface of the shoe sprint performance testing device facing the user during use. As shown in the drawings, Figure 4 and 5 , the test table 13 is a horizontal surface, which is arranged on the bottom wall of the upper chamber 111 and opposite to the first window 1111, and the test table 13 also extends out of the first window 1111. The first sliding rail 131 is arranged on the test table 13. The first sliding rail 131 is arranged on the left side and the right side of the test table 13, and the extension direction of the first sliding rail 131 is parallel to the extension direction of the shoe sole on the test table 13. The first sliding rail 131 is a T-shaped sliding rail, that is, the projection of the first sliding rail 131 on the plane perpendicular to the test table 13 and perpendicular to the extension direction of the first sliding rail 131 is T-shaped, so that when the first sliding rail 131 is in sliding cooperation with the sliding groove 3121, the sliding groove 3121 cannot be separated from the first sliding rail 131 in the direction perpendicular to the test table 13.

[0043] As shown in the drawings, Figure 2 , 4 and 7, the lifting mechanism 12 comprises a third driving member 121 and a lifting member 122. The lifting member 122 is at least partially located above the test table 13, and the third driving member 121 is used to drive the lifting member 122 to reciprocate in the direction perpendicular to the test table 13, so as to adjust the height of the forefoot head assembly 2 to adapt to the thickness of different shoe soles. The lifting member 122 comprises a lifting rod 1221 perpendicular to the test table 13, and the third driving member 121 is used to drive the lifting rod 1221 to reciprocate in the direction perpendicular to the test table 13, so as to drive the lifting member 122 to reciprocate in the direction perpendicular to the test table 13.

[0044] Specifically, as shown in the drawings, Figure 2 ,4 As shown in Figure 7, the lifting component 122 includes a lifting rod 1221, a guide rod 1222, a first mounting base 1223, a second mounting base 1224, and a third mounting base 1225. Two lifting rods 1221 are provided, symmetrically arranged on the left and right sides of the test platform 13, respectively. Each lifting rod 1221 extends vertically and is fixed to the bottom wall of the upper chamber 111. One end of each lifting rod 1221 is located inside the lower chamber 112, and the other end is located above the test platform 13. In this embodiment, each lifting rod 1221 is a ball screw.

[0045] Two guide rods 1222 are provided, symmetrically arranged on the left and right sides of the test platform 13, and corresponding to the two lifting rods 1221 respectively. Each guide rod 1222 extends vertically upward from the bottom wall of the first cavity. The guide rods 1222 serve as guides in the lifting mechanism 12.

[0046] like Figure 2 , 3 As shown in Figures 4 and 7, the cross-section of the first mounting base 1223 is approximately U-shaped. The left arm of the first mounting base 1223 has two through holes running vertically through it for the left-side lifting rod 1221 and guide rod 1222 to pass through, and the right arm has two through holes running vertically through it for the right-side lifting rod 1221 and guide rod 1222 to pass through. The openings of the grooves on the first mounting base 1223 face forward. The two lifting rods 1221 and the first mounting base 1223 are interference-fitted, so that each lifting rod 1221 drives the first mounting base 1223 to rise and fall synchronously during lifting and lowering. The left arm of the first mounting base 1223 has a first hole 12231 running through it along the extension direction of the left arm, and the first hole 12231 communicates with the two through holes on the left arm. The right arm of the first mounting base 1223 has a second hole 12232 running through it along the extension direction of the right arm, and the second hole 12232 communicates with the two through holes on the right arm.

[0047] like Figure 2 , 4 As shown in Figure 7, the cross-section of the second mounting base 1224 is roughly in the shape of a straight line, and its two ends are provided with through holes that extend vertically through the center, allowing the guide rods 1222 on the left and right sides to pass through.

[0048] like Figure 2 , 4 As shown in Figure 7, the third mounting base 1225 is a seat extending vertically, with its upper end fixedly connected to the second mounting base 1224, and its other end located between the left and right arms of the first mounting base 1223 and fixedly connected to the first mounting base 1223. The third mounting base 1225 is provided with a second slide rail 12251 extending vertically on both its left and right sides.

[0049] like Figure 2As shown, the third driving member 121 is installed in the lower chamber 112 of the frame body 11, which is a driving motor. The third driving member 121 drives one end of the two lifting rods 1221 located in the lower chamber 112 to rotate, thereby driving the lifting rods 1221 to ascend and descend along the vertical direction. It should be understood that the third driving member 121 and the lifting rods 1221 are not limited to the driving motor and the ball screw exemplified in the embodiment, and any mechanism commonly used in the art that can achieve vertical lifting shall be within the protection scope of the present application.

[0050] As shown in FIG. 1, Figure 4 The forefoot pressing head assembly 2 is installed on the frame 1, and further, the forefoot pressing head assembly 2 is installed on the part of the lifting member 122 above the test table 13 and reciprocally slides with the lifting member 122 along the direction perpendicular to the test table 13. The forefoot pressing head assembly 2 comprises a first driving member (not shown in the figure), a first body 21 and a first pressing head 22 located above the forefoot area of the shoe sole. The first driving member drives the first pressing head 22 to reciprocally move along the direction perpendicular to the test table 13.

[0051] Specifically, the first body 21 extends along the vertical direction and reciprocally slides with the second sliding rail 12251 along the vertical direction. The first pressing head 22 is fixed to the bottom end of the first body 21. The first driving member is a linear motor, which is used to drive the first body 21 to reciprocally slide along the second sliding rail 12251. It should be understood that the first driving member is not limited to the linear motor exemplified in the embodiment, and any mechanism commonly used in the art that can achieve the same motion shall be within the protection scope of the present application.

[0052] As shown in FIG. 1, Figure 4 and 5 The heel pressing head assembly 3 is installed on the frame 1. Further, the heel pressing head assembly 3 reciprocally slides on the frame 1 in parallel to the extension direction of the shoe sole; the position of the heel pressing head assembly 3 can be adjusted according to different sizes of the shoe sole, so that the forefoot area and the heel area of the shoe sole of different sizes can correspond to the first pressing head 22 and the second pressing head 33, facilitating the detection of shoe soles of different sizes. The extension direction of the above-mentioned first sliding rail 131 is the same as the sliding direction of the heel pressing head assembly 3. The heel pressing head assembly 3 is provided with a sliding groove 3121 and a locking member 313. The sliding groove 3121 reciprocally slides with the first sliding rail 131 and is configured to be unable to be separated from the sliding rail along the direction perpendicular to the test table 13; the locking member 313 is installed on the heel pressing head assembly 3 and is configured to be suitable for adjusting the length of the extension into the sliding groove 3121 to abut against or away from the sliding rail.

[0053] Specifically, as shown in FIG. 1, Figure 4 and Figure 5As shown, the heel indenter assembly 3 comprises a second body 31, a second driving member 32 and a second indenter 33 above the heel region of the sole, the second driving member 32 drives the second indenter 33 to reciprocate in a direction perpendicular to the test table 13.

[0054] As shown in Figure 4 and Figure 5 the second body 31 comprises a connecting plate 311, two supports 312 and a locking member 313. The two supports 312 each extend in a vertical direction, and the bottom end of each support 312 is provided with a sliding groove 3121 adapted to the first sliding rail 131. A threaded hole is provided in the side groove wall of each sliding rail or any sliding groove 3121, and communicates with the sliding groove 3121. The connecting plate 311 extends in a horizontal direction, and its two ends are respectively fixed to the top ends of the two supports 312. The locking member 313 is a screw, which is threadedly connected to the threaded hole in the groove wall of the sliding groove 3121. By rotating the locking member 313, the length of the locking member 313 extending into the sliding groove 3121 can be adjusted, so as to abut against or move away from the sliding rail. When it is necessary to adjust the position of the heel indenter assembly 3, the locking member 313 is adjusted to move away from the first sliding rail 131. When the position of the heel indenter assembly 3 is adjusted to the right position, the locking member 313 is adjusted to abut against the first sliding rail 131, so that the heel indenter assembly 3 is positioned on the first sliding rail 131 and does not move relative to the first sliding rail 131.

[0055] The second indenter 33 is fixed to the output end of the second driving member 32.

In the present embodiment, the second driving member 32 is not limited to the electric cylinder in the present embodiment, and any mechanism commonly used in the art which can achieve the same movement shall be within the protection scope of the present application.

[0057] As shown in Figure 4 the first measuring device 4 is installed on the test table 13 or the first indenter 22, and comprises a first force sensor and a timing sensor. The first force sensor is used to measure the rebound force of the forefoot region of the sole during the process that the first indenter 22 abuts against and moves away from the forefoot region of the sole. The timing sensor is used to measure the time of the process that the first indenter 22 abuts against and moves away from the forefoot region of the sole. By combining the time and the rebound force, the change of the rebound force in different time periods can be known, which is helpful for analyzing the rebound of the sole.

[0058] As shown in Figure 5 the second measuring device 5 is installed on the test table 13 or the second indenter 33, and comprises a second force sensor. The second force sensor is used to abut against the upper surface of the heel region of the sole to measure the rebound force of the heel region of the sole during the process that the first indenter 22 abuts against and moves away from the forefoot region of the sole.

[0059] In the present embodiment, as shown in Figure 4 andFigure 5 As shown, the first measuring device 4 is installed on the first pressure head 22, and the second measuring device 5 is installed on the second pressure head 33. When the first pressure head 22 and the second pressure head 33 are subjected to the reaction force of the sole, the first force sensor, the timing sensor and the second force sensor start measuring. It should be understood that the installation positions of the first measuring device 4 and the second measuring device 5 are not limited to the manner exemplified in the present embodiment, and they can also be installed at positions corresponding to the forefoot region and the heel region of the sole on the test bed surface 13.

[0060] As shown in Figure 2 and 3 The locking handle 6 includes a rotating part 61, a first clamping part 62 and a second clamping part 63.

[0061] As shown in Figure 2 , 3 and 6, the rotating part 61 rotates with the lifting member 122 about a first axis perpendicular to the extending direction of the lifting rod 1221, and is limited in the direction of the first axis, i.e. the rotating part 61 cannot move along the direction of the first axis. Specifically, the rotating part 61 is provided with two. Each rotating part 61 includes a rotating rod 611 and a rotating handle 612. One end of each rotating rod 611 penetrates through the cavity wall of the front chamber 111 of the rack 1 and extends into the first hole 12231 of each first mounting seat 1223 to achieve rotating connection with the lifting member 122 about the first axis, and the other end is located outside the upper chamber 111 and is fixedly connected with the rotating handle 612. The rotating handle 612 abuts against the outer wall of the upper chamber 111, and the part of the rotating rod 611 located in the upper chamber 111 is provided with a limiting protrusion 6111 adapted to abut against the cavity wall of the front chamber 111, so that the rotating part 61 is limited in the direction of the first axis.

[0062] The first clamping part 62 is installed on the lifting member 122 and extends perpendicular to the lifting rod 1221, and one end of the first clamping part 62 also abuts against the side wall of the lifting rod 1221. Specifically, the first clamping part 62 is placed in the first hole 12231, which is a tubular body adapted to the first hole 12231; the first clamping part 62 is sleeved outside the rotating rod 611, and the inner hole diameter is greater than the outer diameter of the rotating rod 611. The end of the first clamping part 62 close to the lifting rod 1221 is provided with an arc surface adapted to the outer wall of the lifting rod 1221.

[0063] The second clamping portion 63 is arranged on the lifting member 122 and extends in the same direction as the first clamping portion 62 and is screwed with the rotating portion 61. Specifically, the second clamping portion 63 is arranged in the first hole 12231 and is a tubular body matched with the first hole 12231; the second clamping portion 63 is screwed with the rotating rod 611 of the rotating portion 61 in the first hole 12231 through the inner hole thereof. The second clamping portion 63 is provided with an arc surface matched with the outer wall of the lifting rod 1221 at one end close to the lifting rod 1221. The second clamping portion 63 is configured to move towards the first clamping portion 62 to abut against the outer wall of the lifting rod 1221 or move away from the first clamping portion 62 to be separated from the outer wall of the lifting rod 1221 when the rotating portion 61 rotates.

[0064] Since the locking handle 6 is limited in the direction of the first axis, the second clamping portion 63 moves towards or away from the first clamping portion 62 by rotating the rotating portion 61. When the lifting rod 1221 is lifted to the position, the second clamping portion 63 is moved towards the first clamping portion 62 and abuts against the outer wall of the lifting rod 1221 by rotating the locking handle 6, so that the lifting rod 1221 is clamped by the first clamping portion 62 and the second clamping portion 63, and the positioning of the lifting rod 1221 is more stable. When it is necessary to adjust the lifting rod 1221, the first clamping portion 62 is moved away from the first clamping portion 62 and separated from the outer wall of the lifting rod 1221 by rotating the locking handle 6, so that the lifting rod 1221 is released and the height of the lifting rod 1221 can be adjusted.

[0065] As shown in Figure 2 The lubricating assembly 7 is arranged on the frame 1 and is used to supply lubricating liquid to the forefoot pressing head assembly 2, the heel pressing head assembly 3 and the lifting mechanism 12. Specifically, the lubricating assembly 7 is arranged in the lower chamber 112 of the frame 1 and is provided with liquid delivery channels (not shown in the figure) respectively connected to the friction positions of the forefoot pressing head assembly 2, the heel pressing head assembly 3 and the lifting mechanism 12, so as to deliver lubricating liquid through the liquid delivery channels to reduce the friction resistance and wear.

[0066] As shown in Figure 4 The air cylinder 8 is arranged on the lifting member 122 and always has an upward force. In this embodiment, the air cylinder 8 is provided with two air cylinders respectively arranged on the left side and the right side of the third mounting seat 1225, and each air cylinder 8 always has an upward force.

[0067] As shown in Figure 2 The two-in-one member 9 is arranged on the frame 1 and is used to adjust the upward force of the air cylinder 8. Specifically, the two-in-one member 9 is arranged in the lower chamber 112 of the frame 1 and includes an air pressure reducing valve and a filter. The air pressure reducing valve is used to adjust the air pressure to adjust the upward force of the two air cylinders 8. The filter is used to filter the air source.

[0068] Through the setting of the cylinder 8 and the two-piece 9, during the process of the forefoot pressing head stamping, the cylinder 8 always has upward force, so that the equipment is more stable during operation, and the shaking and vibration during operation are reduced.

[0069] The control module (not shown in the figure) is installed on the rack 1, and is used for controlling the first driving member, the second driving member 32 and the third driving operation and collecting the measurement data of the first measurement device 4 and the second measurement device 5. The sensors in the first measurement device and the second measurement device 5 transmit the measured data to the control module. The control module can also set the loading time, the loading force value, the unloading time, the cycle number and the like when the forefoot stamping assembly is stamping, and can display the collected data. The forefoot pressing head assembly 2 and the heel pressing head assembly 3 are controlled by the control module, and the control module can also collect the moving distance of the first pressing head 22 and the second pressing head 33, and according to the measured moving distance, the deformation degree of the corresponding region of the sole during the test process can be known.

[0070] The embodiment also provides a shoe test method, which adopts the shoe sprint performance test equipment described above.

[0071] The sole is placed on the test table 13, and the forefoot region and the heel region of the sole correspond to the first pressing head 22 and the second pressing head 33 respectively.

[0072] The second driving member 32 is controlled to drive the second pressing head 33 to move towards the heel region of the sole and abut against the upper surface of the heel region of the sole.

[0073] The first driving member is controlled to drive the first pressing head 22 to move towards the forefoot region of the sole, and to stamp the forefoot region of the sole and then move away from the forefoot region of the sole.

[0074] The first measurement device 4 measures the resilience of the forefoot region of the sole during the process that the first pressing head 22 stamps the forefoot region of the sole and then moves away from the forefoot region of the sole.

[0075] The second measurement device 5 measures the resilience of the heel region of the sole during the process that the first pressing head 22 stamps the forefoot region of the sole and then moves away from the forefoot region of the sole.

[0076] The control module collects the measurement data of the first measurement device 4 and the second measurement device 5.

[0077] After the second pressing head 33 is pressed against the upper surface of the heel region of the shoe sole, the first driving member drives the first pressing head 22 to press the forefoot region of the shoe sole and move away from the forefoot region of the shoe sole. The first measuring device 4 measures the rebound force of the forefoot region of the shoe sole. The rebound of the forefoot region of the shoe sole can be analyzed according to the measured data. During the process that the first pressing head 22 presses the forefoot region of the shoe sole and moves away from the forefoot region of the shoe sole, the second measuring device measures the rebound force of the heel region of the shoe sole. The rebound of the heel region of the shoe sole can be analyzed according to the measured data. The test can link the forefoot and the heel. The boost effect of the shoe sole on the foot during the process that the forefoot lands and the heel lifts can be analyzed according to the measured data.

[0078] The use process of the shoe boost performance test device of the embodiment is specifically as follows:

[0079] As shown in Figures 1 to 7 , first, the shoe sole is placed on the test table 13. The position of the shoe sole is adjusted so that the forefoot region of the shoe sole corresponds to the first pressing head 22. The locking member 313 of the heel pressing head assembly 3 is adjusted. The position of the heel pressing head assembly 3 is slid so that the heel region of the shoe sole corresponds to the second pressing head 33.

[0080] When the boost effect of the shoe sole on the foot during the process that the forefoot lands and the heel lifts needs to be tested, the second driving member 32 drives the second pressing head 33 to move to press against the upper surface of the heel region of the shoe sole. Then, the test parameters such as the loading time, the loading force value, the unloading time and the cycle number of the forefoot pressing head assembly 2 are set in the control module. The first driving member drives the first pressing head 22 to impact the forefoot region of the shoe sole and move away from the forefoot region of the shoe sole. In this process, the first measuring device 4 and the second measuring device 5 collect the rebound force and time of the shoe sole. According to the force, time and deformation degree collected by the control module, the rebound of the heel during the process that the forefoot lands can be known. Thus, the boost effect of the shoe sole on the foot during the process that the heel lifts can be known.
