Description

Technical Field

[0001] This utility model belongs to the technical field of foot sole testing equipment, and specifically relates to a force-measuring shoe. Background Technology

[0002] Force-measuring shoes are a type of high-tech footwear that integrates pressure or force sensors. They can monitor the wearer's gait, plantar pressure distribution, and biomechanical data in real time, and are widely used in fields such as medical rehabilitation, sports science, and human-computer interaction.

[0003] Prior patent CN218869534U discloses an exoskeleton shoe, specifically comprising: a shoe body and a pressure assembly disposed inside the shoe body; the pressure assembly includes an upper shoe plate, a lower shoe plate, a control circuit board, and a bridge-type steel plate sensor for sensing pressure; a bridge-type steel plate sensor and a control circuit board are disposed between the upper and lower shoe plates; wherein at least one bridge-type steel plate sensor is provided; the control circuit board and the bridge-type steel plate sensor are electrically connected, and the bridge-type steel plate sensor solves the technical problems of "high installation requirements, large fluctuation range of detection data, and easy false alarms", achieving the technical effect of simple installation and accurate data measurement. However, when a rigid sensor is used for plantar pressure, it will lead to insufficient flexibility and discomfort when worn. Currently, there are also force-measuring shoes that use thin-film flexible sensors instead of rigid sensors, but although thin-film sensors can improve flexibility and wearing comfort, they have problems such as poor sensor lifespan and signal changes due to bending of the thin film during measurement, leading to interference in the measurement.

[0012] In some embodiments, the first end of the connector has a plurality of first fixing holes spaced apart along its length, the front fixing member has a second fixing hole, and the connector is connected to the front end of the front fixing member by a first fastener fastening into the first fixing holes and the second fixing holes; and / or,

[0013] The second end of the connector is provided with a plurality of third fixing holes spaced apart along its own length direction, and the rear fixing member is provided with a fourth fixing hole. The connector is connected to the rear fixing member by a second fastener fastening the third fixing holes and the fourth fixing holes.

[0014] In some embodiments, the connector is a long strip-shaped structure, with the wide side of the connector facing the wearer's foot.

[0015] In some embodiments, the connector is a carbon fiber sheet; the width of the connector is 8mm to 20mm, and the thickness of the connector is 0.8mm to 2mm.

[0016] In some embodiments, two connectors are provided, which are arranged side by side and spaced apart along the width direction of the front fastener.

[0017] In some embodiments, both the front fixing member and the rear fixing member include a first bearing plate and a second bearing plate disposed below the first bearing plate, and the sensor is disposed between the first bearing plate and the second bearing plate, the sensor being a rigid sensor;

[0018] The second bearing plate has elastic properties, or both the first bearing plate and the second bearing plate have elastic properties.

[0024] The technical solution provided by this utility model has the following advantages and effects:

[0025] This force-measuring shoe connects the front end of the front fixing component to the rear fixing component via an elastic connector. This allows the front and rear fixing components to bend relative to each other, enabling the wearer's forefoot and heel to bend relative to each other when wearing the shoe. Since the front fixing component is only connected to the connector at its front end, the connector can separate from the front fixing component after the connection point. This minimizes the constraint on the forefoot when the wearer's toes leave the ground and allows the forefoot sensor to remain basically horizontal with the ground during the toe-off phase. This effectively avoids the upper surface bending moment caused by the flexion of the metatarsophalangeal joint on the sensor of the front fixing component, greatly reducing the off-center load on the sensor and thus improving the accuracy and stability of the measurement data.

[0034] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0035] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0036] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0037] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0038] This utility model embodiment provides a force-measuring shoe 100, such as Figures 1 to 5 As shown, the force-measuring shoe 100 includes a front fixing member 1, a rear fixing member 2, and a connecting member 3.

[0039] Both the front fixing member 1 and the rear fixing member 2 are equipped with sensors 4; these sensors 4 can be used to monitor the wearer's gait, plantar pressure distribution, and biomechanical data in real time. Specifically, in this embodiment, the sensor 4 is mainly used to measure the interaction force or similar interaction force between the wearer and the ground during exercise (mainly for walking, running, and other conventional movements). The front fixing member 1 has a front end 11 and a rear end 12 connected to the front end 11, and the front end 11, rear end 12, and rear fixing member 2 are arranged sequentially. The connecting member 3 has elastic properties, and its opposite ends are connected to the front end 11 and the rear fixing member 2, respectively. The connecting member 3 spans across the rear end 12, and the portion of the connecting member 3 spanning across the rear end 12 can be separated from the rear end 12. It should be noted that the force-measuring shoe 100 is worn on the wearer's foot, specifically designed for use with shoes. The wearer's shoe is fixed to the force-measuring shoe 100. The front fixing member 1 corresponds to the relatively forward area of ​​the front fixing member 1, which is close to the forefoot of the wearer. The wearer's rear fixing member 2 corresponds to the relatively forward area of ​​the front fixing member 1, which is close to the heel of the wearer. Since the front end 11, rear end 12, and rear fixing member 2 of the front fixing member 1 are arranged sequentially, the front end 11 of the front fixing member 1 can correspond to the forward position of the forefoot, such as the area near the metatarsophalangeal joint, and the rear end 12 of the front fixing member 1 can correspond to the rear position of the forefoot, such as the area behind the metatarsophalangeal joint. It should be noted that the force-measuring shoe 100 is also equipped with cables connecting the two sensors 4 and a protective shell for protecting the cables. The protective shell can be set between the connector 3 and the front fixing member 1 and the rear fixing member 2 to effectively protect the cables from being squeezed or punctured by protruding stones or other objects on the ground during walking. In addition, the force-measuring shoe 100 also includes a conventional data acquisition unit to realize functions such as data acquisition, data analysis and communication, as well as other conventional components such as power supply, which are not specifically limited here.

[0040] Understandably, the elastic performance of connector 3 refers to its ability to fully recover its initial shape and size after deformation under stress and removal of the external force. However, it has almost no stretching performance, meaning that connector 3 hardly changes length in the direction of force, such as tension or compression. This ensures the length between the front and rear foot fixing parts during wear, preventing the forefoot or heel from slipping out of the force-measuring shoe 100. Therefore, the front end 11 of the front fixing part 1 is connected to the rear fixing part 2 through connector 3, allowing the front fixing part 1 and the rear fixing part 2 to bend relative to each other but not stretch. This allows the wearer's forefoot and heel to bend relative to each other after wearing the force-measuring shoe 100 and to return to their original shape. Furthermore, since the front fixing member 1 is only connected to the connector 3 at its front end 11, the portion of the connector 3 spanning the rear end 12 can be separated from the rear end 12. That is, the portion of the connector 3 spanning the rear end 12 of the front fixing member 1 is in an independent state relative to the rear end 12, rather than a fixed connection state. This allows the connector 3 to be separated from the front fixing member 1 after the connection point, which can minimize the constraint of the front fixing member 1 on the forefoot when the wearer's toes leave the ground. Moreover, since the front fixing member 1 can maintain a basically horizontal state with the ground during the push-off phase, the sensor 4 on the front fixing member 1 will not be subjected to the upper surface bending moment generated by the bending of the metatarsophalangeal joint, and the off-center load is also greatly reduced, thereby improving the accuracy and stability of the measurement data.

[0041] In some embodiments, such as Figure 2 As shown, the connector 3 is a long strip-shaped sheet structure, with its wide surface facing the wearer's foot. It should be noted that the long strip-shaped connector 3 typically has a large length and width, and a small thickness. Therefore, the larger plane extending along the length and width directions is the wide surface of the connector 3, and the smaller plane extending along the thickness direction is the side surface of the connector 3. The two ends of the connector 3 are defined with the longest extension direction of the sheet as the length axis, and the two ends are located along the length axis. In this embodiment, the connector 3 is connected to the front end 11 of the front fixing member 1 and the rear fixing member 2 at their respective ends along the length axis. The wide surface of the connector 3 faces the wearer's foot, and the side surface of the connector 3 is perpendicular to the foot. This orientation allows the connector 3 to fully contact the foot during wearer movement (such as walking or foot flexion), flexing flexibly with foot movements and automatically adapting to changes in the shape of the foot.

[0042] In some embodiments, the connector 3 is a carbon fiber sheet, which has the characteristics of high-efficiency energy rebound, thus enabling it to flexibly bend with foot movements, quickly adapt to changes in the shape of the sole, and has good fatigue resistance and stability. Of course, in other embodiments, the connector 3 is not limited to a carbon fiber sheet; other materials with elastic properties and the ability to adapt to changes in the shape of the sole can be used, and no particular limitation is made here. The width of the connector 3 is 8mm to 20mm, and the thickness of the connector 3 is 0.8mm to 2mm.

[0043] In some embodiments, such as Figure 2 As shown, two connectors 3 are provided, arranged side-by-side and spaced apart along the width direction of the front fixing member 1. It should be noted that the width direction of the front fixing member 1 corresponds to the direction from the inside to the outside of the foot, that is, the width direction of the wearer's foot. By connecting the front fixing member 1 and the rear fixing member 2 with these two connectors 3, more even support can be provided, and the connection stability of the two connectors 3 is better. During the dynamic activity of the force-measuring shoe 100, it can effectively reduce the problem of excessive pressure at a single point and has better adaptability, responding independently to different deformation needs in different areas of the foot.

[0044] In some embodiments, such as Figure 2 As shown, the front end 11 and the rear end 12 of the front fixing member 1 are integrally formed. This integral structure is achieved by directly fabricating the front end 11 and rear end 12 into a continuous, single component through a single processing step, eliminating the need for secondary assembly such as welding or bolts. The front end 11 and rear end 12 are spatially distinguished only by their relative positions on the foot, rather than by any fundamental structural or functional differences. Of course, in other embodiments, the front end 11 and rear end 12 of the front fixing member 1 can also be separate connected structures; no particular limitation is imposed here.

[0045] In some embodiments, the front fastener 1 has a front edge 16 and a rear edge 17 extending along the front end 11 to the rear end 12, and a centerline disposed between the front edge 16 and the rear edge 17. The connection area between the connector 3 and the front fastener 1 is at least partially located between the front edge 16 and the centerline. Specifically, the connection area between the connector 3 and the front fastener 1 can be entirely located between the front edge 16 and the centerline, or partially located between the front edge 16 and the centerline, so that the connection area between the connector 3 and the front fastener 1 is substantially entirely located in front of the centerline, and the connector 3 is connected to the front fastener 1 near the toe. Preferably, the connection position of the connector 3 and the front fastener 1 corresponds to the position in front of the metatarsophalangeal joint of the wearer's foot. This allows the connector 3 to be separated from the front fixing member 1 at the position corresponding to the toe, preferably behind the metatarsophalangeal joint, improving wearing comfort and effectively preventing the sensor 4 on the front fixing member 1 from being affected by the upper surface bending moment caused by the bending of the metatarsophalangeal joint, thereby improving the accuracy and stability of the measurement data.

[0046] In some embodiments, the distance between the rear edge of the connection area between the connector 3 and the front fixing member 1 and the centerline is 0mm to 10mm. Specifically, the rear edge of the connection area between the connector 3 and the front fixing member 1 can be located on the side of the centerline near the rear edge 17, or the rear edge of the connection area between the connector 3 and the front fixing member 1 can be located on the side of the centerline near the front edge 16. It should be noted that the rear edge of the connection area between the connector 3 and the front fixing member 1 refers to the edge of the connection area between the connector 3 and the front fixing member 1 near the rear edge 17. It can be understood that by setting the rear edge of the connection area between the connector 3 and the front fixing member 1 near the centerline, the connector 3 can be stably fixed to the toe position of the front fixing member 1, without affecting the wearing comfort and detection accuracy.

[0047] In some embodiments, such as Figure 1As shown, the front fixing member 1 has first strap fixing members 15 on opposite sides of its extension direction from the front fixing member 1 to the rear fixing member 2. It should be noted that the opposite sides of the front fixing member 1 along its extension direction correspond to the inner and outer sides of the wearer's foot. The first strap fixing members 15 are used to fix the straps, so that the wearer's shoe is fixed to the force-measuring shoe 100 at the position corresponding to the forefoot. The first strap fixing members 15 are located at the center line of the front fixing member 1, and are positioned corresponding to the position before or at the metatarsophalangeal joint of the wearer. Specifically, the first strap fastener 15 can be positioned at the front end 11 of the front fastener 1, which corresponds exactly to the position of the wearer's metatarsophalangeal joint, or the first strap fastener 15 can be positioned at the front end 11 of the front fastener 1, which corresponds to a position slightly forward of the metatarsophalangeal joint. Therefore, the connector 3 after this position can bend and separate from the sensor 4. When the wearer is exercising, during the toe-off phase, the wearer's metatarsophalangeal joint can bend and is not constrained by the strap and the front fastener 1, thus improving comfort and the accuracy and stability of the measurement data.

[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the first end of the connector 3 has a plurality of first fixing holes 31 spaced apart along its length, and the front fixing member 1 has a second fixing hole. The connector 3 is connected to the front fixing member 1 by a first fastener fastening the first fixing holes 31 and the second fixing holes. Specifically, by having a plurality of first fixing holes 31 spaced apart along its length at the first end of the connector 3, the first fixing holes 31 at corresponding length positions and the second fixing holes of the front fixing member 1 can be connected by the first fastener according to the wearer's foot length, thereby adjusting the overall length of the force-measuring shoe 100 to accommodate different foot lengths of the wearer and improve versatility. The first fastener can be a bolt, a positioning pin, or a buckle, etc., as long as it enables a detachable connection between the two, and no special restrictions are imposed here. In this embodiment, the front fixing member 1 has two spaced second fixing holes, and two first fasteners are provided accordingly. The two first fasteners fix the two first fixing holes 31 and the two second fixing holes to form the above-mentioned connection area. The two-point fixing method can effectively prevent the connector 3 from rotating relative to the front fixing member 1, so as to stably fix the connector 3 at a specific position of the front fixing member 1.

[0049] In some embodiments, such as Figure 1 and Figure 2As shown, the second end of the connector 3 has a plurality of third fixing holes 32 spaced apart along its length, and the rear fixing member 2 has a fourth fixing hole. The connector 3 is connected to the rear fixing member 2 by a second fastener that engages with the third fixing holes 32 and the fourth fixing hole. Specifically, by having a plurality of third fixing holes 32 spaced apart along its length at the second end of the connector 3, the third fixing holes 32 at corresponding length positions and the fourth fixing hole of the rear fixing member 2 can be connected by the second fastener according to the wearer's foot length. This allows adjustment of the overall length of the force-measuring shoe 100 to accommodate different foot lengths of the wearer and improve versatility. The second fastener can be a bolt, a positioning pin, or a buckle, as long as it allows for a detachable connection between the two, and no particular limitation is made here. In this embodiment, the rear fixing member 2 has two fourth fixing holes, and two second fasteners are provided accordingly. The two second fasteners fix the two third fixing holes 32 and the two fourth fixing holes. The two-point fixing method can effectively prevent the connector 3 from rotating relative to the rear fixing member 2, so as to stably fix the connector 3 at a specific position of the rear fixing member 2.

[0050] In some embodiments, such as Figures 2 to 5As shown, both the front fixing member 1 and the rear fixing member 2 include a first bearing plate 13 and a second bearing plate 14 disposed below the first bearing plate 13. The sensor 4, which is a rigid sensor, is disposed between the first bearing plate 13 and the second bearing plate 14. The two bearing plates and the sensor 4 are connected by multiple bolts. Specifically, the first bearing plate 13 has a first threaded hole, and the upper end of the sensor 4 has a second threaded hole corresponding to the first threaded hole. The first bearing plate 13 is sequentially fixed to the first and second threaded holes by bolts to connect to the upper end of the sensor 4. The second bearing plate 14 has a third threaded hole, and the lower end of the sensor 4 has a fourth threaded hole corresponding to the third threaded hole. The second bearing plate 14 is sequentially fixed to the third and fourth threaded holes by bolts to connect to the lower end of the sensor 4. One sensor 4 or multiple (≥ two) sensors 4 can be disposed between the first bearing plate 13 and the second bearing plate 14. When only one sensor 4 is disposed, the sensor 4 needs to have strong resistance to off-center loads. When multiple (≥ two) sensors 4 are used, if a single sensor 4 has poor resistance to off-center loads (or lacks off-center load resistance), the fixed ends of each sensor 4 are connected together by the first support plate 13, and the measuring ends of each sensor 4 are connected together by the second support plate 14. This allows them to jointly resist the influence of off-center loads on the measurement, greatly improving the measurement accuracy of the sensor 4. At least the second support plate 14 has elastic properties. Specifically, it may be that only the second support plate 14 has elastic properties, or both the first and second support plates 13 have elastic properties; no particular limitation is made here. When the wearer wears the force-measuring shoe 100, the second support plate 14 contacts the ground, and the first support plate 13 contacts the wearer's sole. The elastic properties of the support plates must allow them to fully recover their initial shape and size after deformation under stress and the removal of the external force, while also providing sufficient support to support the wearer's feet during walking. Therefore, at least the second support plate 14 is configured to have elastic properties, providing elastic cushioning during the heel strike and a certain degree of elasticity during toe lift-off, achieving a flexible wearing effect and improving wearing comfort. Rigid sensors are characterized by their robust structure, strong resistance to deformation, and almost no deformation under pressure, ensuring accurate and reliable pressure data. When used in conjunction with an elastic support plate, they only transmit pressure without bending or twisting with the foot, resulting in a long service life.

[0051] In some embodiments, such as Figure 2As shown, both the first support plate 13 and the second support plate 14 are square carbon fiber plates, with their wide surfaces facing the wearer's foot. The square-plate support plates have a large length and width, and a small thickness. Therefore, the larger planes extending along the length and width directions are the wide surfaces of the support plates, and the smaller planes extending along the thickness direction are the side surfaces. By using square-plate carbon fiber plates for both the first support plate 13 and the second support plate 14, the carbon fiber plates possess high-efficiency energy rebound characteristics and excellent fatigue resistance. That is, both the first support plate 13 and the second support plate 14 are elastic, achieving a better flexible wearing effect. In this embodiment, by having the wide surface of the support plate facing the wearer's foot and the side surface perpendicular to the foot, this orientation allows the support plate to provide stable support to the wearer during movement (such as walking or foot flexion) through full contact between the wide surface and the foot, thus creating a flexible wearing effect. In addition, the first support plate 13 and the second support plate 14 have an arc-shaped transition structure around their perimeter to prevent sharp edges from causing injury to the wearer during exercise.

[0052] In some embodiments, such as Figure 3 As shown, the cross-sectional areas of the first support plate 13 and the second support plate 14 are both larger than the cross-sectional area of ​​the sensor 4. The vertical projection surfaces of the first support plate 13 and the second support plate 14 cover the vertical projection surface of the sensor 4. It should be noted that the vertical projection surface refers to the projection surface along the Z-axis in a three-dimensional coordinate system. Because the cross-sectional areas of the two support plates are both larger than the cross-sectional area of ​​the sensor 4, the mating structure of the first support plate 13, the sensor 4, and the second support plate 14 has a similar I-shaped structure in the longitudinal section, thereby forming a cantilever structure between the front fixing member 1 and the rear fixing member 2 to provide effective elastic cushioning performance during the heel landing and toe lift-off phases.

[0053] In some embodiments, the first strap fastener 15 extends outward along the side of the front fastener 1, and the first strap fastener 15 has a first strap hole 151. By passing the strap through the first strap hole 151, the strap can be fixed to the force-measuring shoe 100, so that the wearer's shoe is fixed to the force-measuring shoe 100 at the position of the forefoot via the strap.

[0054] In some embodiments, such as Figure 1As shown, the rear fixing member 2 has two second strap fixing members 21 respectively provided on opposite sides along the extension direction of the front fixing member 1 to the rear fixing member 2. It should be noted that the opposite sides of the rear fixing member 2 along the extension direction of the front fixing member 1 to the rear fixing member 2 correspond to the inner and outer sides of the wearer's foot. The second strap fixing member 21 is used to fix the strap, so that the wearer's shoe is fixed to the force testing shoe 100 by the strap at the position of the heel and the rear foot. The second strap fixing members 21 on opposite sides of the rear fixing member 2 are arranged one-to-one to form two pairs of second strap fixing members 21. The second strap fixing member 21 has a second strap hole 211. By passing the strap through the second strap hole 211, the strap can be fixed to the force testing shoe 100. Specifically, a pair of second strap fasteners 21 corresponding to the rear fixing member 2 fixes one strap. Therefore, two straps can be fixed by two pairs of second strap fasteners 21, thereby fixing the instep and heel of the wearer's foot, and fixing the wearer's shoe to the position of the instep and heel on the force-measuring shoe 100. All four second strap fasteners 21 are vertically arranged on the rear fixing member 2. The second strap holes 211 on the pair of second strap fasteners 21 adjacent to the front fixing member 1 are inclined from top to bottom towards the front fixing member 1, while the second strap holes 211 on the other pair of second strap fasteners 21 are inclined from top to bottom away from the front fixing member 1. This allows the fixed straps to adapt to the position of the instep and heel, forming a comfortable and secure binding.

[0055] In summary, the force-measuring shoe 100 is connected to the rear fixation member 2 via a flexible connector 3 at the front end 11 of the front fixation member 1. This allows the front fixation member 1 and the rear fixation member 2 to bend relative to each other, enabling the wearer's forefoot and heel to bend relative to each other when wearing the force-measuring shoe 100. Since the front fixation member 1 is only connected to the connector 3 at its front end 11, the connector 3 can be separated from the front fixation member 1 after the connection point. This minimizes the constraint on the forefoot of the wearer when the toes leave the ground, and allows the forefoot sensor 4 of the front fixation member 1 to remain basically horizontal with the ground during the toe-off phase. This effectively avoids the upper surface bending moment generated by the bending of the metatarsophalangeal joint on the sensor 4 of the front fixation member 1, greatly reducing the off-center load on the sensor 4, thereby improving the accuracy and stability of the measurement data.

[0056] Therefore, the force measuring shoe 100 has the characteristics of simple structure, light weight, convenient and sturdy wearing, while improving the accuracy and stability of measurement data and reducing the impact of wearing the force measuring shoe 100 on walking.

[0057] The above embodiments are not an exhaustive list based on the present invention, and there may be other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
