Description

[Technical Field]

[0001] The present invention relates to a detection device and footwear. [Background technology]

[0002] In recent years, technologies have been proposed that use a detection device placed on the bottom or insole of footwear to detect loads applied to the sole of the foot. The load detected by the detection device is used, for example, to analyze a user's walking condition, health condition, and exercise performance. For example, a detection device configured as an insole includes a detection element placed inside an insole body and an electronic module. The electronic module includes, for example, a signal processing circuit that processes signals from the detection element, a power source such as a battery that supplies electrodes to the detection element, and a charging connector. Furthermore, Patent Document 1 discloses a configuration in which an electronic board on which electronic components are mounted is placed inside an insole body while being housed in an electronic box.

[0003] [Patent Document 1] Special Publication No. 2020-536702 Summary of the Invention [Problem to be solved by the invention]

[0004] In a configuration in which an electronic board is housed in an electronic box, if a charging connector is mounted on the electronic board as an electronic component, the electronic box needs to be provided with an exposure hole to expose the connection portion of the charging connector to the outside. In this case, when an external force is applied to the electronic box, the charging connector can move through the exposure hole, causing the electronic board to bend and deform, and stress is concentrated on the portion of the electronic board where the charging connector is mounted. [Means for solving the problem]

[0005] The following describes an embodiment that solves the above problem. [Aspect 1] A detection device equipped with a detection element that detects physical information obtained from the soles of the feet, the detection device comprising: an electronic box having an internal storage space; and an electronic board housed in the electronic box and having electronic components mounted thereon; the electronic box having an exposure hole for exposing the electronic components mounted on the electronic board to the outside of the electronic box; and when viewed in a plan view of the electronic box in the direction in which the electronic components are exposed from the exposure hole, at least one of the area surrounding the exposure hole and the area overlapping the exposure hole has a protrusion that abuts against at least one of the electronic board and the electronic components.

[0006] According to the above configuration, the electronic box has a protrusion that abuts against the electronic board around the exposure hole or in a portion overlapping the exposure hole. Therefore, when an external force is applied to the electronic box, the protrusion, which is a part of the electronic box, abuts against the electronic board or electronic component, thereby suppressing bending of the electronic board due to excessive movement of the electronic component exposed through the exposure hole. As a result, local stress concentration on the electronic board caused by the exposure hole provided in the electronic box for exposing the electronic component can be suppressed.

[0007] [Aspect 2] A detection device as described in aspect 1, comprising a rechargeable power supply unit housed in the electronic box and supplying power to the detection element, the electronic component including a charging connector for charging the power supply unit, and the charging connector being exposed to the outside of the electronic box through the exposure hole.

[0009] [Aspect 4] The detection device according to aspect 3, wherein the protrusion includes an upper protrusion that protrudes downward from the top wall, and the upper protrusion abuts against an upper surface of at least one of the electronic board and the electronic component.

[0010] [Aspect 5] A detection device as described in aspect 3, wherein the electronic box has a bottom wall located below the storage space, and the protrusion includes a lower protrusion that protrudes upward from the bottom wall, and the lower protrusion abuts against the lower surface of at least one of the electronic board and the electronic component.

[0011] [Aspect 6] The electronic box has a bottom wall located below the storage space, and the protrusion includes an upper protrusion protruding downward from the top wall and a lower protrusion protruding upward from the bottom wall, and the upper protrusion abuts against an upper surface of at least one of the electronic board and the electronic component, and the lower protrusion abuts against a lower surface of at least one of the electronic board and the electronic component.

[0015] An embodiment of the detection device 10 of the present invention embodied in an insole for detecting a load will be described below. 1, the detection device 10 includes a base 20 used as an insole of footwear, and a detection unit 30 attached to the base 20. Having flexibility means that the detection device is soft enough to be partially compressed in the thickness direction in accordance with the movement of the sole of the foot when walking, jumping, landing, etc.

[0016] <Base> The base 20 includes an upper housing 21 that forms the upper part of the base 20, and a lower housing 22 that forms the lower part of the base 20. The detection unit 30 is attached inside the base 20 in a manner that it is sandwiched between the upper housing 21 and the lower housing 22.

[0017] The lower surface of the upper housing 21 is formed in a flat shape, and the upper surface is formed in a three-dimensional shape that conforms to the shape of the sole of the foot. Examples of materials for the upper housing 21 include EVA (ethylene vinyl acetate) and PU (polyurethane). The cushioning and resilience of the insole can be adjusted by adjusting either or both of the material for the upper housing 21 and the thickness of the upper housing 21. In addition, a skin 23 that covers the upper housing 21 is attached to the upper surface of the upper housing 21.

[0018] Lower housing 22 is a part formed in the shape of a flat plate, and on its upper surface are provided sensor housing 24 and box housing 25 for housing the components of detection unit 30. Sensor housing 24 and box housing 25 are recesses provided on the upper surface of lower housing 22. Lower housing 22 is formed by stacking and integrating a bottom plate 22b without holes under a perforated plate 22a having through holes 26 shaped to correspond to sensor housing 24 and box housing 25. Examples of materials constituting lower housing 22 include EVA (ethylene vinyl acetate) and PU (polyurethane).

[0019] The base 20 also includes an adhesive layer 27 that bonds the lower surface of the upper housing 21 to the upper surface of the lower housing 22. The adhesive layer 27 is not particularly limited, and may be an adhesive layer using a sheet material such as double-sided tape, or an adhesive layer using an adhesive.

[0020] <Detection unit> As shown in FIG. 1, the detection unit 30 has four detection elements 31. The four detection elements 31 consist of three toe sensors 31a to 31c and one heel sensor 31d. The toe sensors 31a to 31c are detection elements for the toes that detect the load applied to the area of ​​the sole where the flesh is thick, extending from the ball of the big toe to the ball of the little toe. The heel sensor 31d is a detection element for the heel that detects the load applied to the heel of the sole.

[0021] The sensor housings 24 provided in the lower housing 22 of the base 20 are provided at positions where the detection elements 31 are to be disposed. Each detection element 31 is housed in the sensor housing 24. A known pressure-sensitive sensor using a piezoelectric element or the like can be used as the pressure sensor constituting each detection element 31. In particular, considering that the detection elements 31 are placed on the soles of the feet, it is preferable to use a capacitance-type pressure sensor made of an elastomer using a dielectric elastomer from the viewpoints of stretchability and durability. Examples of the dielectric elastomer include cross-linked polyrotaxane, silicone elastomer, acrylic elastomer, and urethane elastomer.

[0022] The detection unit 30 further includes an electronic box 35 and wiring 36. The configuration housed in the electronic box 35 will be described later. The electronic box 35 is housed in the box housing portion 25 and is adhered to the lower surface of the upper housing 21 by an adhesive layer 35a similar to the adhesive layer 27. The electronic box 35 and the box housing portion 25 are located at the plantar arch, or the so-called arch position. Therefore, the electronic box 35 is located closer to the heel than the toe sensors 31a to 31c.

[0023] The wiring 36 electrically connects each connection terminal of each detection element 31 to the electronic box 35. The wiring 36 has flexibility that allows it to deform in accordance with the base 20. Examples of the flexible wiring 36 include a flexible printed wiring board and a lead wire.

[0024] <Electronic box details> 2 to 4, electronic box 35 is a rectangular box-shaped member having an internal storage space S. Electronic box 35 includes an upper case 40 and a lower case 50, and forms the rectangular box shape by combining upper case 40 and lower case 50. Upper case 40 and lower case 50 are each integrally formed from, for example, a resin material or the like.

[0025] The upper case 40 is a lidded square box-shaped member that opens downward and includes a substantially rectangular top wall 41 and an upper peripheral wall 42 that is formed along the periphery of the top wall 41 and extends downward. Ribs 41A that reinforce the top wall 41 are formed on the inner surface of the top wall 41 (see FIG. 4). The ribs 41A are formed in a lattice pattern that extends vertically and horizontally along the periphery of the top wall 41.

[0026] The top wall 41 of the upper case 40 is provided with an exposure portion 43 for exposing an upper portion of a charging connector 63 (described later) from the electronic box 35. The exposure portion 43 includes a circular annular wall 43A that protrudes from the inner surface of the top wall 41 and an exposure hole 43B that is provided at the lower end of the annular wall 43A. The annular wall 43A is formed in a shape that gradually reduces in diameter from top to bottom. The annular wall 43A is formed as a part of the top wall 41.

[0027] An upper fitting portion 42A that fits into the lower case 50 is provided at the lower end of the upper peripheral wall 42. The upper fitting portion 42A is a recess formed along the circumferential direction of the upper peripheral wall 42. The upper fitting portion 42A is a portion that fits into a lower fitting portion 52A provided on the lower peripheral wall 52 of the lower case 50, which will be described later.

[0028] The lower case 50 is a rectangular box-shaped member with a bottom that opens upward, and includes a substantially rectangular bottom wall 51 and a lower peripheral wall 52 that is formed along the periphery of the bottom wall 51 and extends upward. A partition wall 51A is provided on the inner surface of the bottom wall 51, dividing the interior of the lower case 50 into a first housing section S1 and a second housing section S2. A support wall 51B is provided on the inner surface of the bottom wall 51 in a portion located in the first housing section S1, for supporting an electronic board 61 or electronic component 62 (described later) from below and forming a gap between the electronic board 61 and the bottom wall 51.

[0029] A lower fitting portion 52A that fits into the upper case 40 is provided at the upper end of the lower peripheral wall 52. The lower fitting portion 52A is a protrusion formed along the circumferential direction of the lower peripheral wall 52. The lower fitting portion 52A is a portion that fits into an upper fitting portion 42A provided on the upper peripheral wall 42 of the upper case 40. The upper peripheral wall 42 of the upper case 40 and the lower peripheral wall 52 of the lower case 50 are fixed together by a known method such as adhesive, with the upper fitting portion 42A and the lower fitting portion 52A fitted together.

[0030] A rechargeable power supply unit 60 such as a battery and an electronic board 61 are housed in the storage space S within the electronic box 35. The power supply unit 60 supplies power to each detection element 31. The power supply unit 60 is connected to the electronic board 61 and the wiring 36 by wiring (not shown).

[0031] Electronic components 62 and a charging connector 63 are mounted on the electronic board 61. The charging connector 63 is a type of electronic component 62. The electronic board 61 is in the shape of a flat plate having an upper surface and a lower surface located on the opposite side.

[0032] Charging connector 63 is mounted on the upper surface of electronic board 61 at a position overlapping exposure hole 43B in a plan view of electronic box 35 viewed from above. The plan view of electronic box 35 viewed from above (hereinafter simply referred to as plan view) corresponds to the plan view of electronic box 35 viewed in the direction in which charging connector 63 is exposed through exposure hole 43B. Charging connector 63 is a cylindrical member having an outer circumferential shape that is slightly smaller than exposure hole 43B of upper case 40. The lower end surface of charging connector 63 is fixed to the upper surface of electronic board 61.

[0033] An upper portion of charging connector 63 is inserted through exposure hole 43B of upper case 40 and protrudes above annular wall 43A of upper case 40, thereby being exposed on the upper surface of upper case 40. An insertion port 63A into which a terminal of a charging cable (not shown) is inserted is formed at the upper end of charging connector 63 exposed from the upper surface of upper case 40. The outer peripheral surface of charging connector 63 and the inner peripheral edge of exposure hole 43B of upper case 40 are fixed together with an adhesive (not shown). This adhesive functions as a seal that prevents foreign matter and liquid from entering electronic box 35.

[0034] The charging connector 63 is a portion to which a charging terminal of a charging cable (not shown) extending from a charging device is detachably connected when charging the power supply unit 60 housed in the electronic box 35. The charging device is prepared separately when charging the power supply.

[0035] Examples of the electronic components 62 include elements that constitute a signal processing circuit that processes signals from each detection element 31, elements that constitute a memory unit that stores various information such as signals from each detection element 31 and information obtained by processing those signals, and elements that constitute a communication unit that communicates with the outside. As an example, the electronic components 62 are mounted on both the upper and lower surfaces of the electronic board 61. In this case, the electronic board 61 is a double-sided mounting board in which the electronic components 62 are mounted on both the upper and lower surfaces.

[0036] 3, a first contacted portion 61A, which is a flat portion on which no electronic component 62 is mounted, is provided around the portion on the top surface of electronic board 61 where charging connector 63 is mounted. A second contacted portion 61B, which is a flat portion on which no electronic component 62 is mounted, is provided on the bottom surface of electronic board 61 at a portion opposite to the portion on which charging connector 63 is mounted.

[0037] <Upper protrusion and lower protrusion> 2 to 7, the upper case 40 has two upper protrusions 44 that protrude downward from an annular wall 43A that is part of the top wall 41. Each upper protrusion 44 is cylindrical, and a flat support surface 44A is formed at its tip. The support surface 44A abuts in a surface-to-surface contact manner against a first abutted portion 61A on the upper surface of the electronic board 61. The protrusion height of the upper protrusions 44 is greater than that of the ribs 41A.

[0038] 2, the upper protrusion 44 is disposed around the exposure hole 43B in a plan view. In a plan view, the upper protrusion 44 is preferably disposed at a position closer to the periphery of the exposure hole 43B. For example, the upper protrusion 44 is preferably disposed so that at least a portion thereof is located closer to the periphery of the exposure hole 43B than the outer periphery of the annular wall 43A, and more preferably is disposed at a position where its outer periphery is in contact with the periphery of the exposure hole 43B. The two upper protrusions 44 are disposed so as to be located on radially opposite sides of the exposure hole 43B, with the exposure hole 43B sandwiched between them.

[0039] 2 to 7, the lower case 50 has two lower protrusions 53 that protrude upward from a portion of the inner surface of the bottom wall 51 that is located in the second housing section S2. Each lower protrusion 53 is cylindrical, and has a flat support surface 53A formed at its tip. The support surface 53A abuts in a surface-to-surface contact manner against a second abutted portion 61B on the lower surface of the electronic board 61. The protrusion height of the lower protrusions 53 is greater than that of the partition wall 51A and the support wall 51B.

[0040] As shown in Fig. 2, lower protrusion 53 is disposed near exposure hole 43B in a plan view. In a plan view, lower protrusion 53 is preferably disposed at a position closer to the center of charging connector 63. For example, in a plan view, lower protrusion 53 is preferably disposed at a position overlapping the outer periphery of charging connector 63 or at a position closer to the center than that position, more preferably at a position overlapping the center of charging connector 63, and even more preferably at the center of charging connector 63. Furthermore, as shown in Fig. 2, lower protrusion 53 is preferably disposed at a position overlapping exposure hole 43B in a plan view.

[0041] Here, an example of the arrangement of the two upper protrusions 44 and the two lower protrusions 53 in a plan view will be described. As shown in Fig. 2, an imaginary line L1 passing through the centers of the two upper protrusions 44 and an imaginary line L2 passing through the centers of the two lower protrusions 53 in a plan view are assumed.

[0042] An example of the two upper protrusions 44 and the two lower protrusions 53 is arranged so that at least one of the imaginary line L1 and the imaginary line L2 intersects with the front-to-back direction of the foot (the arrangement shown in FIG. 2).

[0043] An example of the two upper protrusions 44 and the two lower protrusions 53 is arranged so that at least one of the imaginary line L1 and the imaginary line L2 is parallel to the front-to-back direction of the foot (the arrangement shown in FIG. 2).

[0044] An example of the two upper protrusions 44 and the two lower protrusions 53 is that the two upper protrusions 44 and the two lower protrusions 53 are arranged so that the intersection of the imaginary line L1 and the imaginary line L2 is located within the exposure hole 43B (the arrangement shown in Figure 2).

[0045] In one example, the two upper protrusions 44 and the two lower protrusions 53 are arranged so that the imaginary line L1 and the imaginary line L2 are aligned in the same line. Next, the operation of this embodiment will be described.

[0046] When walking or exercising while wearing footwear with an insole inserted as the detection device 10, a localized external force may be applied to the electronic box 35 of the detection device 10. Examples of such cases include when climbing stairs while pressing the arch of the foot against a corner of the stairs, and when stepping on a hard object smaller than the electronic box 35, such as a pebble, with the arch of the foot.

[0047] In such a case, an external force is applied to electronic box 35, tending to bend electronic box 35. Then, an external force is also applied to electronic board 61 housed inside electronic box 35, tending to bend it in the same direction, via electronic box 35.

[0048] In this case, in the case of an electronic box having a conventional configuration, if the electronic box is provided with exposure hole 43B that exposes charging connector 63, charging connector 63 can be excessively inserted into exposure hole 43B. Conversely, charging connector 63 can be excessively pushed into housing space S of the electronic box through exposure hole 43B. As a result, electronic board 61 is significantly curved at the portion where charging connector 63 is mounted, causing stress to concentrate in that portion.

[0049] On the other hand, in the case of electronic box 35 of the present embodiment, in a plan view, upper protrusion 44 and lower protrusion 53 that abut against electronic board 61 are provided around exposure hole 43B and in a portion of electronic box 35 that overlaps exposure hole 43B. Therefore, the abutment between upper protrusion 44, which is a part of electronic box 35, and electronic board 61 can suppress excessive movement of charging connector 63 in a direction (upward) into exposure hole 43B. Similarly, the abutment between lower protrusion 53, which is a part of electronic box 35, and electronic board 61 can suppress excessive movement of charging connector 63 in a direction (downward) to be pushed into accommodation space S of electronic box 35.

[0050] This makes it possible to suppress large upward or downward convex bending of electronic board 61 at the portion where charging connector 63 is mounted when a local external force is applied to electronic box 35. As a result, it is possible to suppress local stress concentration on electronic board 61 at the portion where charging connector 63 is mounted, i.e., local stress concentration on electronic board 61 caused by exposure hole 43B being provided in electronic box 35. Although details are omitted, simulation results have also been obtained that show that local stress concentration on electronic board 61 is suppressed when upper protrusion 44 and lower protrusion 53 are provided.

[0051] Next, the effects of this embodiment will be described. (1) Detection device 10 includes electronic box 35 having storage space S therein, and electronic board 61 housed in electronic box 35 and having charging connector 63 mounted thereon. Electronic box 35 includes exposure hole 43B for exposing electronic components (charging connector 63) to the outside of electronic box 35. In a plan view, protrusions (upper protrusion 44 and lower protrusion 53) that come into contact with electronic board 61 are provided around exposure hole 43B and in the portion of electronic box 35 that overlaps exposure hole 43B.

[0052] According to the above configuration, it is possible to suppress localized stress concentration on the electronic substrate 61 caused by the exposure hole 43B being provided. (2) The detection device 10 is housed in the electronic box 35 and includes a rechargeable power supply unit 60 that supplies power to the detection element 31. The electronic components include a charging connector 63 for charging the power supply unit 60. The charging connector 63 is exposed to the outside of the electronic box 35 through the exposure hole 43B.

[0053] The charging connector 63 is configured to be necessarily exposed to the outside of the electronic box 35. Therefore, the configuration (1) above is particularly effective in suppressing local stress concentration on the electronic board 61.

[0054] (3) The protrusion includes an upper protrusion 44 that protrudes downward from the top wall 41. The upper protrusion 44 abuts against the upper surface of the electronic board 61. According to the above configuration, excessive movement of charging connector 63 in the direction (upward) into exposure hole 43B can be suppressed. This makes it possible to suppress large upward curvature of electronic board 61 at the portion where charging connector 63 is mounted.

[0055] (4) The electronic box 35 has a bottom wall 51 located below the accommodation space S. The protrusion includes a lower protrusion 53 that protrudes upward from the bottom wall 51. The lower protrusion 53 abuts against the lower surface of the electronic board 61.

[0056] The above configuration can prevent charging connector 63 from moving excessively (downward) toward housing space S of electronic box 35. This can prevent electronic board 61 from bending significantly downward at the portion where charging connector 63 is mounted.

[0057] (5) The electronic box 35 is not potted, i.e., the housing space S is not filled with an encapsulating resin. In this case, the electronic substrate 61 is not fixed to the electronic box 35 by the encapsulating resin, and therefore the electronic substrate 61 is prone to deformation when an external force is applied to the electronic box 35. Therefore, the above configuration (1) is particularly effective in suppressing local stress concentration on the electronic substrate 61. Furthermore, the above configuration also makes it possible to use electronic components 62 whose performance deteriorates due to potting treatment.

[0058] This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. The electronic component 62 exposed to the outside of the electronic box 35 through the exposure hole 43B is not limited to the charging connector 63. For example, instead of the charging connector 63, a communication connector for wired communication may be exposed to the outside of the electronic box 35.

[0059] The power supply unit 60 may be omitted. The exposure hole 43B may be provided in a wall other than the top wall 41 of the electronic box 35, for example, in the bottom wall 51.

[0060] The upper protrusion 44 and the lower protrusion 53 may be configured to come into contact with the electronic board 61 when the electronic board 61 is slightly deformed. The number of upper protrusions 44 may be one, or may be three or more. The arrangement of the upper protrusions 44 may also be changed.

[0061] The contact state of the upper protrusion 44 with the electronic board 61 is not limited to surface contact, but may be point contact or line contact. Furthermore, the upper protrusion 44 may be configured to contact the electronic component 62 instead of the electronic board 61.

[0062] The number of the lower protrusions 53 may be one, or may be three or more. The arrangement of the lower protrusions 53 may also be changed. The contact state of the lower protrusion 53 with the electronic board 61 is not limited to surface contact, but may be point contact or line contact. Also, the lower protrusion 53 may be configured to contact the electronic component 62 instead of the lower protrusion 53 itself.

[0063] Either the upper protrusion 44 or the lower protrusion 53 may be omitted. The shapes of the upper protrusion 44 and the lower protrusion 53 are not limited to a cylindrical shape, but may be other shapes, such as a polygonal prism, a pyramid, or a cone.

[0064] The configuration for sealing the gap between charging connector 63 and electronic box 35 is not limited to the configuration in which annular wall 43A is bonded to charging connector 63. For example, instead of annular wall 43A, an annular sealing member may be fixed to electronic box 35, and the inner circumferential surface of the sealing member may be pressed against charging connector 63 to achieve sealing.

[0065] The position where the upper protrusion 44 is provided on the top wall 41 is not limited to the annular wall 43A. For example, the upper protrusion 44 may be provided on a flat portion of the top wall 41, or on the sealing member.

[0066] In the above embodiment, the detection elements 31 are common pressure sensors having the same shape, but some or all of them may be non-common pressure sensors. The number and arrangement of the detection elements 31 provided in the detection device 10 are not limited to the configuration of the above embodiment.

[0067] The number and arrangement of the electronic boxes 35 provided in the detection device 10 are not limited to the configurations of the above-described embodiments. For example, a plurality of electronic boxes 35 may be provided. The detection element 31 for detecting body information obtained from the soles of the feet is not limited to a pressure sensor. Examples of the detection element 31 other than a pressure sensor include a temperature sensor, an odor sensor, and an inertial sensor.

[0068] The detection device 10 may be applied to footwear. [Explanation of symbols]
