Description

Technical Field

[0001] The present invention belongs to the technical field of foot pressure detection equipment, and in particular is a walking motion simulation mechanical device for multi-point pressure detection in shoes based on multiple mechanical sensors. Background Art

[0002] After shoes are manufactured, testing equipment is often used to spot-check a batch of shoes to ensure that all data about the shoes meet standards. This type of testing equipment simulates a person walking in the shoes and uses pressure sensors to record internal data to test the quality or internal condition of the shoes.

[0003] For example, the invention patent with publication number CN118319243A in the field of foot pressure detection technology discloses a device for dynamic foot pressure distribution testing of shoes, including a pressure-measuring shoe, several flexible pressure sensors attached to the bottom of the shoe cavity of the pressure-measuring shoe, a data acquisition and processing module installed on the outer side of the pressure-measuring shoe, and a power supply module. The data acquisition and processing module is also equipped with wireless communication technologies such as Bluetooth or Wi-Fi to transmit the collected data to terminal devices such as mobile phones and computers for further analysis and display.

[0004] Combining the above cases with actual conditions, we found the following problems: When detecting the internal conditions of shoes through simulated walking, it is usually difficult to detect uphill and downhill conditions. Or, when going uphill and downhill, due to the change in the inclination of the stepping point, the pressure of the simulation equipment is reduced during simulated walking and cannot reach the normal walking pressure of pedestrians, which leads to inaccurate data. Summary of the Invention

[0005] The purpose of the present invention is to provide a walking motion simulation mechanical device for multi-point pressure detection in shoes based on multiple mechanical sensors. By setting up a simulation component and a pedal component, the pedal inclination can be adjusted during simulated walking, and through the cooperation of a guide plate and a clamping block, after the pedal inclination is changed, sufficient pressure is still maintained between the foot frame and the pedal to ensure that it is consistent with the pedaling force when a person walks, improve the data accuracy when going up and down slopes, and thus solve the above-mentioned problems of the prior art.

[0006] To achieve the above objectives, the present invention provides a walking motion simulation mechanical device for detecting multi-point pressure in a shoe based on multiple force sensors, comprising two bilaterally symmetrical support frames, a simulation component for simulating walking provided at the upper portion between the two support frames, and a pedal component matched with the simulation component provided at the lower portion between the two support frames; The simulation component includes a rotating box, a plurality of sliding seats regularly arranged on the curved surface of the rotating box, and two guide plates symmetrically arranged on the front and rear sides of the rotating box. The front and rear side walls are slidably connected to the outer sides with a clamping block, a shoe rack is fixed between the two clamping blocks, and the inner side of the guide plate is provided with a guide groove adapted to the size of the clamping block. The pedal assembly includes a pedal and two rotating structures for driving the pedals. The rotating structure includes a rotating plate coaxially fixed to the middle of the corresponding side wall of the pedal, a transmission rod and a third hinge rod. The bottom end of the third hinge rod is hinged to the edge of the rotating plate surface, and the top end is hinged to the bottom end of the transmission rod. The transmission rod is provided with a plurality of left and right horizontal cross bars, and the outer side of the guide plate is provided with a plurality of fixed cylinders corresponding to the plurality of said cross bars one by one. A push rod is slidably connected in the fixed cylinder, and the cross bar passes through the corresponding fixed cylinder on the left and right. The outer end face of the push rod is inclined, and the cross bar corresponds to the position of the outer end face of the corresponding push rod.

[0007] In this setting, when the turntable drives the pedal to rotate counterclockwise by a certain angle, the pedal becomes inclined with the front lower and the back higher, simulating a downhill slope. The pedal drives the turntable to rotate counterclockwise, causing the guide plate to move closer to the middle and contact the block, causing the shoe rack to slide outward during the rotation process, thereby ensuring that there is sufficient pressure between the shoes on the shoe rack and the pedal. This avoids the situation where the shoe rack's rotation radius remains unchanged after the pedal is tilted, resulting in the shoe rack being unable to reach the pressure of a pedestrian's normal walking when in contact with the pedal, making the detected shoe pressure data inaccurate.

[0008] In the technical solution of the present invention, a first motor is fixed to the middle part of the outer side of the rear support frame, and the output shaft of the first motor passes through the rear support frame and the rear guide plate from the outside to the inside in sequence and is coaxially fixedly connected to the rotating box.

[0009] In this arrangement, the rotating box is driven to rotate by the first motor, and the direction of rotation can be changed.

[0010] In the technical solution of the present invention, several of the blocks are distributed in a ring shape, the guide groove is in a convex ring shape as a whole and the bottom end protrudes downward, the guide groove and the block are distributed in the same range, the inner side of the block is fixed to the corresponding side wall of the sliding seat by magnetic attraction, and a sliding groove is provided at the position corresponding to the sliding seat and the block, and the block is fixed to the corresponding shoe rack through the corresponding sliding groove.

[0011] In this setting, when simulating flat walking, the card block is fixed to the innermost side of the sliding seat by magnetic attraction. When the shoe rack contacts the pedal, the card block is subjected to inward pressure. Due to the obstruction of the slide groove, the shoe rack will not rotate left or right, and the card block will not slide inward under the inward pressure, resulting in insufficient pressure between the shoe rack and the pedal.

[0012] In the technical solution of the present invention, the outer end of the fixed cylinder is fixed to the inner wall of the support frame on the corresponding side, the inner end of the push rod is fixed to the outer wall of the corresponding guide plate, the upper and lower rod walls of the push rod are fixed with convex blocks, the inner wall of the fixed cylinder is provided with convex grooves corresponding to the position and size of the convex blocks, and the side wall of the fixed cylinder is provided with a movable opening for the cross bar to move up and down.

[0013] In this setting, the design of the convex block and the convex groove prevents the push rod from rotating in the fixed cylinder, causing the guide plate to shift in position, making the block and the guide groove unable to correspond, and thus rendering the entire device unusable.

[0014] In the technical solution of the present invention, a plurality of openings corresponding to the plurality of sliding seats are provided on the arc-shaped surface of the rotating box, and limiting grooves are symmetrically fixed on the front and rear sides of the sliding seat. The openings and the limiting grooves are both radially arranged, and the openings are provided with limiting blocks corresponding to the position and size of the limiting grooves.

[0015] In this configuration, by providing openings and limiting grooves, the rotating box can drive the sliding seat to rotate and can slide radially to adjust its position.

[0016] In the technical solution of the present invention, a linkage structure is provided inside the rotating box, and the linkage structure includes front and rear transverse fixed rods, a movable block located at the rear end of the fixed rod, and a slider located at the front end of the fixed rod. The front end of the fixed rod is fixedly connected to the front inner wall of the rotating box, and a connecting rod is provided between the movable block and the slider. The movable block and the slider are both slidably connected to the fixed rod, and the outer end surface of the slider is provided with a plurality of first hinge rods regularly distributed in an annular shape, and the plurality of first hinge rods correspond one-to-one to the plurality of sliding seats, and the outer ends of the first hinge rods are hinged to the corresponding inner end surfaces of the sliding seats.

[0017] In this setting, by setting up a linkage structure, when the movable block slides backward, the connecting rod drives the slider to move backward synchronously, and then drives the sliding seat to move radially inward through the first hinge rod, so that the radius of the entire sliding seat is reduced, avoiding the shoe rack from colliding with the higher end of the pedal 301 due to excessive extension when simulating uphill, causing the entire device to fail to operate.

[0018] In the technical solution of the present invention, the rear end of the fixed rod passes through the rear side wall of the rotating box and the rear guide plate in sequence, and the end face is rotatably connected to the rear support frame, the movable block is located between the rear guide plate and the rear support frame, and the movable block is provided with hanging ears on the left and right sides, and a second hinge rod is provided between the hanging ears and the horizontal bar below, the top end of the second hinge rod is hinged to the corresponding hanging ear, and the bottom end is hinged to the corresponding horizontal bar, and the top end of the second hinge rod is tilted outward.

[0019] In this arrangement, by providing a second hinge rod, when the pedal drives the rotating plate to rotate counterclockwise and drives the transmission rod to move upward, the top end of the second hinge rod is pushed outward.

[0020] In the technical solution of the present invention, a rotating block is embedded in the movable block, the front end annular surface of the rotating block passes through the front side wall of the movable block, the rear end of the connecting rod is fixed to the front end surface of the rotating block, the front end of the connecting rod is fixed to the slider, and the rotating block is rotatably connected to the movable block.

[0021] In this setting, a rotating block is provided to prevent the movable block from rotating synchronously with the slider, thereby preventing the entire device from becoming unusable.

[0022] In the technical solution of the present invention, a second motor is fixed to the lower outer wall of the front support frame corresponding to the middle position of the pedal, and the output shaft of the second motor passes through the front support frame and is coaxially fixed to the front side wall of the rotating plate on the corresponding side.

[0023] In this configuration, the second motor drives the rotating plate 312 and the pedal 301 to rotate. In the technical solution of the present invention, the tread of the pedal is made of rubber material driven by a servo motor, and the outer surface roughness of the tread of the pedal is different.

[0024] In this setup, the contact surface between the pedal and the shoe is changed by a servo motor, thereby changing the friction between the two to simulate walking on different roads.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, by setting a simulation component and a pedal component, starting the second motor makes the pedal tilted with the front lower and the back higher. When the turntable rotates counterclockwise, it simulates a downhill slope. At the same time, the third hinge rod pushes the transmission rod upward, driving the cross bar to move upward and push the push rod inward, so that the guide plates on both sides are close to the middle and the blocking block is located in the guide groove. When the shoe rack rotates to contact the pedal, the blocking block will gradually enter the protruding part at the bottom of the guide groove, so that the shoe rack slides outward during the rotation process, reducing the distance between the shoe rack and the pedal, thereby ensuring that there is sufficient pressure between the shoes on the shoe rack and the pedal, and improving the accuracy of the detection data.

[0026] 2. In the present invention, a linkage structure is provided. When the pedal drives the turn plate to rotate counterclockwise and drives the transmission rod to move upward, the top end of the second hinge rod pushes the movable block outward to slide backward, and the connecting rod drives the slider to move backward synchronously, and then drives the sliding seat radially inward through the first hinge rod, so that the radius of the entire sliding seat is reduced, avoiding the shoe rack from colliding with the higher end of the pedal due to excessive extension when simulating uphill, causing the entire device to be unable to operate. At the same time, the inward movement distance is less than the outward protrusion distance of the guide groove guiding the card block. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0029] Unless expressly stated otherwise, throughout the specification, the term “comprise” or variations thereof such as “include” or “comprising” will be understood to include the stated elements or components but not to exclude other elements or components.

[0030] Reference Figures 1-13 As shown, this embodiment provides a technical solution: The present invention discloses a walking motion simulation mechanical device for detecting multiple pressure points inside a shoe based on multiple mechanical sensors. The device comprises two bilaterally symmetrical support frames 100. A simulation component 200 for simulating walking is provided at the upper portion between the two support frames 100. A pedal component 300 supporting the simulation component 200 is provided at the lower portion between the two support frames 100. The simulation component 200 simulates a person wearing shoes and walking on the pedal component 300. The multiple mechanical sensors detect pressure at multiple points inside the shoe. The entire device is controlled by a PLC controller, and pressure data from the mechanical sensors is transmitted via wireless signals. The simulation component 200 includes a rotating box 201, a plurality of sliding seats 208 regularly arranged on the curved surface of the rotating box 201, and two guide plates 203 symmetrically arranged on the front and rear sides of the rotating box 201. The front and rear side walls are slidably connected to the outer sides with a clamping block 206. A shoe rack 202 is fixed between the two clamping blocks 206. The inner side of the guide plate 203 is provided with a guide groove 203a that is adapted to the size of the clamping block 206. When the rotating box 201 rotates counterclockwise, the heel of the shoe rack 202 first contacts the pedal assembly 300, and the outermost end of the shoe rack 202 can be rotated 180° and then fixed. The rotation and fixation can be achieved by the design of the clamping bolt and the clamping slot. This is a prior art and will not be described in detail here. The sliding seat 208 and the shoe rack 202 are driven to rotate to simulate the user wearing shoes and walking; The pedal assembly 300 includes a pedal 301 and two rotating structures 310 for driving the pedal 301. When the pedal 301 is horizontal, the rotating box 201 directly drives the sliding seat 208 and the shoe rack 202 to rotate counterclockwise. When the shoe on the shoe rack 202 rotates until the heel contacts the tread of the pedal 301, the multiple groups of pressure sensors installed inside the shoe will record and transmit signals to the PLC controller. The rotating box 201 continues to rotate, and the vertical distance between the shoe rack 202 and the pedal 301 decreases, so that the pressure exerted by the shoe rack 202 on the pedal 301 increases until the bottom surface of the shoe rack 202 is parallel to the pedal 301. Then, the heel of the shoe rack 202 separates from the pedal 301. At this time, the vertical distance between the shoe rack 202 and the pedal 301 increases, and the pressure between the two will decrease until they are completely separated. This process is consistent with the change in the pressure between the shoe and the road surface when a person walks, which first increases and then decreases. The rotating structure 310 includes a rotating plate 312 fixed coaxially with the middle of the side wall corresponding to the pedal 301, a transmission rod 314 and a third hinge rod 313. The bottom end of the third hinge rod 313 is hinged to the edge of the rotating plate 312, and the top end is hinged to the bottom end of the transmission rod 314. The transmission rod 314 is provided with a plurality of left and right horizontal cross bars 315. The outer side of the guide plate 203 is provided with a plurality of fixed cylinders 204 corresponding to the plurality of cross bars 315. The fixed cylinders 204 are slidably connected to the push rods 205. , the cross bar 315 passes through the corresponding fixed cylinder 204 on the left and right, the outer end surface of the push rod 205 is inclined, and the cross bar 315 corresponds to the outer end surface of the corresponding push rod 205. When the rotating plate 312 drives the pedal 301 to rotate counterclockwise for a certain angle, the pedal 301 is inclined in the front lower and the back higher. When the rotating box 201 rotates counterclockwise, the shoes on the shoe rack 202 and the pedal 301 simulate a downhill slope. When the rotating box 201 rotates clockwise, the shoe rack 202 rotates 180 degrees, and the shoes and the pedals are in a downward slope. 301 simulates an uphill slope, the pedal 301 drives the rotating plate 312 to rotate counterclockwise, so that the third hinge 313 pushes the transmission rod 314 upward and drives the cross bar 315 to move upward, thereby giving an inward thrust to the outer end surface of the push rod 205, so that the push rod 205 drives the guide plate 203 to move closer to the middle and the block 206 is located in the guide groove 203a. When the rotating box 201 drives the shoe rack 202 to rotate, the block 206 will slide in the guide groove 203a. When the shoe rack 202 rotates When the shoe rack 202 moves to contact the pedal 301, the block 206 will gradually enter the protruding part at the bottom of the guide groove 203a, causing the shoe rack 202 to slide outward during the rotation process, thereby ensuring that there is sufficient pressure between the shoes on the shoe rack 202 and the pedal 301, and avoiding the situation where the rotation radius of the shoe rack 202 remains unchanged after the pedal 301 tilts, resulting in the shoe rack 202 being unable to reach the pressure required for normal walking when in contact with the pedal 301, thereby making the detected shoe pressure data inaccurate.

[0031] See also Figure 1 and Figure 2 As shown, a first motor 209 is fixed to the middle part of the outer side of the rear support frame 100 by bolts. The output shaft of the first motor 209 passes through the rear support frame 100 and the rear guide plate 203 from the outside to the inside and is coaxially fixed with the rotating box 201 by bolts. The rotating box 201 is driven to rotate by the first motor 209, and the rotation direction can be changed.

[0032] See also Figure 3-Figure 6As shown, several blocks 206 are distributed in a ring shape, and the guide groove 203a is a convex ring shape as a whole and the bottom end protrudes downward. When the block 206 rotates inside the guide groove 203a to the downward protruding part, the block 206 is released and drives the sliding seat 208 to slide outward, ensuring that when the pedal 301 is tilted, there is sufficient pressure between the shoe rack 202 and the pedal 301. The guide groove 203a and the block 206 are distributed in the same range. The inner side of the block 206 and the corresponding side wall of the sliding seat 208 are fixed by magnetic attraction. When simulating flat walking, The block 206 is fixed to the innermost side of the sliding seat 208 by magnetic attraction. A sliding groove 207 is provided at the corresponding position of the sliding seat 208 and the block 206. The block 206 passes through the corresponding sliding groove 207 and is fixed to the corresponding shoe rack 202. When the shoe rack 202 contacts the pedal 301, the block 206 is subjected to inward pressure. Since the sliding groove 207 is rectangular, it prevents the shoe rack 202 from rotating left and right and the block 206 will not slide inward under the inward pressure, resulting in insufficient pressure between the shoe rack 202 and the pedal 301.

[0033] See also Figure 7-Figure 8 As shown, the outer end of the fixed cylinder 204 is fixed to the inner wall of the corresponding side support frame 100, and the inner end of the push rod 205 is fixed to the outer wall of the corresponding guide plate 203. The upper and lower rod walls of the push rod 205 are fixed with convex blocks, and the inner wall of the fixed cylinder 204 is provided with a convex groove corresponding to the position and size of the convex block. The side wall of the fixed cylinder 204 is provided with a movable opening for the cross bar 315 to move up and down. Through the design of the convex block and the convex groove, the push rod 205 is prevented from rotating in the fixed cylinder 204, which causes the position of the guide plate 203 to be offset, so that the block 206 and the guide groove 203a cannot correspond, and the entire device cannot be used.

[0034] See also Figures 9-13 As shown, the arc surface of the rotating box 201 is provided with a plurality of openings corresponding to the plurality of sliding seats 208 one by one, and the sliding seats 208 are symmetrically fixed with limiting grooves on the front and rear sides. The openings and the limiting grooves are both radially arranged, and the openings are provided with limiting blocks corresponding to the position and size of the limiting grooves, so that the rotating box 201 can drive the sliding seat 208 to rotate while being able to slide radially to adjust the position.

[0035] Specifically, a linkage structure 210 is provided inside the rotating box 201. The linkage structure 210 includes a front and rear transverse fixed rod 211, a movable block 212 located at the rear end of the fixed rod 211, and a slider 213 located at the front end of the fixed rod 211. The front end of the fixed rod 211 is fixedly connected to the front inner wall of the rotating box 201. A connecting rod 214 is provided between the movable block 212 and the slider 213. The movable block 212 and the slider 213 are both slidably connected to the fixed rod 211. The outer end surface of the slider 213 is provided with a plurality of first hinge rods regularly distributed in an annular shape. 215, a plurality of first hinges 215 correspond to a plurality of sliding seats 208 one by one, and the outer ends of the first hinges 215 are hinged to the inner end surfaces of the corresponding sliding seats 208. When the movable block 212 slides backward, the connecting rod 214 drives the slider 213 to move backward synchronously, and then drives the sliding seat 208 to move radially inward through the first hinge 215, so that the radius of the entire sliding seat 208 is reduced, so as to avoid the shoe rack 202 from colliding with the higher end of the pedal 301 due to excessive extension when simulating uphill, causing the entire device to be unable to operate.

[0036] Specifically, the rear end of the fixing rod 211 passes through the rear side wall of the rotating box 201 and the rear guide plate 203 in sequence, and the end face is rotatably connected to the rear support frame 100. The fixing rod 211 can rotate synchronously with the rotating box 201, and the movable block 212 is located between the rear guide plate 203 and the rear support frame 100. The movable block 212 is provided with hanging ears on the left and right sides, and a second hinge 216 is provided between the hanging ears and the lower cross bar 315. The top end of the second hinge 216 is hinged to the corresponding hanging ear, and the bottom end is hinged to the corresponding cross bar 315, and the top end of the second hinge 216 is tilted outward to ensure that when the bottom end of the second hinge 216 is pushed, the top end moves outward, and when the pedal 301 drives the rotating plate 312 to rotate counterclockwise and drives the transmission rod 314 to move upward, the top end of the second hinge 216 is pushed outward.

[0037] Furthermore, a rotating block 217 is embedded in the movable block 212, and the front end annular surface of the rotating block 217 passes through the front side wall of the movable block 212. The rear end of the connecting rod 214 is fixed to the front end surface of the rotating block 217, and the front end of the connecting rod 214 is fixed to the slider 213. The rotating block 217 is rotatably connected to the movable block 212. When the rotating box 201 drives the sliding seat 208 to rotate, the first hinge rod 215 drives the slider 213 to rotate synchronously. By setting the rotating block 217, the movable block 212 and the slider 213 are prevented from rotating synchronously, which makes the entire device unusable. It should be noted that the distance the sliding seat 208 moves inward is less than the distance that the guide groove guides the card block to bulge outward, so as to avoid the sliding seat 208 moving inward. The bulging distance is too small, resulting in that there is still no large pressure between the shoe rack 202 and the pedal 301.

[0038] In addition, a second motor 311 is fixed to the lower outer wall of the front support frame 100 corresponding to the middle position of the pedal 301. The output shaft of the second motor 311 passes through the front support frame 100 and is coaxially fixed to the front wall of the corresponding side turn plate 312. The turn plate 312 and the pedal 301 are driven to rotate by the second motor 311. The first motor 209 and the second motor 311 are both controlled by a PLC controller.

[0039] In addition, it should be noted that the tread of the pedal 301 is made of rubber material driven by a servo motor, and the outer surface roughness of the tread of the pedal 301 is different. The servo motor drives the pedal 301 to change the contact surface with the shoe and thus change the friction between the two to simulate walking on different roads. In addition, a support plate is fixed in the middle of the pedal 301, and the support plate is located below the upper tread to prevent the tread from collapsing when pressed down by the shoe.

[0040] The working principle of the walking motion simulation mechanical device for multi-point pressure detection in shoes based on multiple mechanical sensors in the present invention is as follows: When walking on a simulated flat road, the first motor 209 is started to drive the rotating box 201 to rotate, so that the shoe frame 202 contacts the pedal 301 to simulate pedestrian walking, and the pressure data inside the shoe is transmitted and recorded through multiple groups of pressure sensors.

[0041] When walking on a simulated downhill road, the second motor 311 is started to drive the rotating plate 312 and the pedal 301 to rotate counterclockwise by a certain angle, and the pedal 301 is inclined with the front lower and the back higher. When the rotating box 201 rotates counterclockwise, the shoes on the shoe rack 202 and the pedal 301 simulate a downhill slope. At the same time, the third hinge rod 313 pushes the transmission rod 314 upward to drive the cross bar 315 to move upward, thereby giving the outer end surface of the push rod 205 an inward thrust, so that the push rod 205 drives the guide plate 203 to move closer to the middle and the block 206 is located in the guide groove 203a. When the pedal 301 drives the rotating plate 312 to rotate counterclockwise, thereby driving the transmission rod 314 to move upward, the top end of the second hinge rod 216 pushes the movable block 212 outward to slide backward, and the connecting rod 214 drives the slider 213 to move backward synchronously, thereby driving the sliding seat 208 radially inward through the first hinge rod 215, so that the extended radius of the entire sliding seat 208 is reduced, thereby preventing the shoe rack 202 from extending too much and colliding with the higher end of the pedal 301 during simulated uphill riding, causing the entire device to malfunction; When the rotating box 201 drives the shoe rack 202 to rotate, the block 206 will slide in the guide groove 203a. When the shoe rack 202 rotates to contact the pedal 301, the block 206 will gradually enter the protruding part at the bottom of the guide groove 203a, causing the shoe rack 202 to slide outward during the rotation process, thereby ensuring that there is sufficient pressure between the shoes on the shoe rack 202 and the pedal 301, and avoiding that after the pedal 301 tilts, if the rotation radius of the shoe rack 202 remains unchanged, the shoe rack 202 cannot reach the normal walking pressure of pedestrians when contacting the pedal 301, and the detected shoe pressure data is inaccurate. After the adjustment is completed, the first motor 209 is started to drive the rotating box 201 to rotate counterclockwise.

[0042] When walking on a simulated uphill road, the adjustment steps are the same as those for walking on a simulated downhill road. After the adjustment is completed, the shoe rack 202 needs to be rotated 180° and then fixed, and the first motor 209 is started to drive the rotating box 201 to rotate clockwise.
