Description

Support layer for smart insole

The description below relates to the support layer for the smart insole.

The smart insole may be provided with electronic devices for interaction with the user's sole. For example, a pressure sensor for measuring the pressure applied from the user's sole or a vibrator for applying vibration to the user's sole may be provided. When the smart insole is equipped with a pressure sensor and/or vibrator, the pressure sensor must withstand the user's load, so it must have an appropriate level of durability. In addition, in the case of the smart insole, a situation in which a relatively large pressure is frequently applied according to a user's activity, a situation in which higher durability is required.

In addition, in the case of the smart insole, durability of the connection between the pressure sensor and/or the vibrator and the control unit is important. The pressure sensor and/or the vibrator is provided on or inside the insole body part. On the other hand, the control unit is difficult to be provided on the insole body part due to the thin thickness of the insole body part, and is generally provided on the back counter of the shoe or the midsole of the shoe. Due to this structure, the support layer having a pressure sensor and/or a vibrator and having one end connected to the control unit may be deformed according to a user's activity. Even if it is deformed according to the user's activity, there is a need for a support layer capable of maintaining stability.

The electronic device disposed on the support layer may be physically and electrically connected to the controller through a pin pitched PET film (FPCB) provided at one end of the support layer. Among the support layers, the part connected to the control unit receives load and torsion force. The existing support layer has limited flexibility with respect to the length and hardness of the connected part and the available angle of circuit movement is limited and narrow, so the pad part of the support layer is It may come off from the connector of the control unit, or the connected part may be torn. In addition, in order to prevent the pad part of the support layer from coming off, when bonding, molding, or fixing holes are added and connected to each other, the connection part is weak due to internal stress and a tearing problem occurs, thereby preventing the operation of the electronic device. can occur

The above-mentioned background art is possessed or acquired by the inventor in the process of deriving the disclosure of the present application, and it cannot be said that it is necessarily known technology disclosed to the general public prior to the present application.

An object of one embodiment is to provide a support layer for a smart insole with improved durability.

A support layer for a smart insole according to an embodiment includes: a body layer for supporting an electronic device as referenced in the claims; a connection layer extending from the body layer; and a connection pad provided at an end of the connection layer spaced apart from the body layer, wherein the connection layer includes: a distal part including an end spaced apart from the body layer; a proximal part including the other end abutting the body layer, extending from the body layer in a first direction, and positioned at a different height from the distal part; and a connecting part connecting the distal part and the proximal part.

The proximal part may be provided parallel to the body layer, and the distal part may be positioned below the body layer.

The connecting part may include: a horizontal part provided at the same height as the proximal part and extending from the proximal part in a second direction crossing the first direction; and a height adjustment part having one end connected to the horizontal part and the other end connected to the distal part.

The support layer for the smart insole may further include a protective layer attached to one surface of the body layer and the connection layer.

The protective layer may include a main protective part attached to one surface of the body layer; and a connection protection part extending from the main protection part and attached to one surface of the connection layer.

A width of the main protection part may be greater than a width of the connection protection part based on a direction perpendicular to the first direction.

The edge portion of the main protection part may be spaced apart from the edge portion of the body layer.

The edge portion of the protective layer may be spaced apart from the edge portion of the connection layer.

The protection layer and the connection pad may be provided on the same surface of the connection layer, and the protection layer may be spaced apart from the connection pad in a longitudinal direction of the connection layer.

The protection layer and the connection pad may be provided on different surfaces of the connection layer, and the protection layer may overlap at least a portion of the connection pad in a direction perpendicular to a length direction of the connection layer.

The horizontal part and the distal part may overlap each other in a direction perpendicular to an upper surface of the horizontal part.

The horizontal part and the height adjustment part may form an acute angle with each other, and at least a portion may overlap each other with respect to a direction perpendicular to a length direction of the horizontal part.

The connection layer may have a shape bent a plurality of times.

The distance between the horizontal part and the distal part is variable while the relative positions of the proximal part and the distal part are fixed when the connection layer is viewed in a direction perpendicular to the upper surface of the proximal part .

When the connection layer is viewed in a direction perpendicular to the upper surface of the proximal part, the connection layer may have an 'L' shape.

The support layer for the smart insole according to an embodiment may have improved durability. The support layer for the smart insole increases the length of the connection layer formed from the pad part connected to the control unit to the base layer supporting the electronic device in a limited space, thereby having high durability against tension due to load and distortion.

Specifically, the support layer for the smart insole may increase durability by attaching a protective layer to one or both sides of the base layer including the circuit. In addition, even if distortion occurs by providing an offset between the protective layer and the base layer, a phenomenon in which the protective layer is separated from the support layer and/or a phenomenon in which the protective layer comes into contact with the pad portion may be prevented.

1 and 2 , a support layer for a smart insole according to an embodiment may be provided in the smart insole to implement electrical and physical connection between the electronic devices S1-S4 and the controller C. The electronic elements S1 - S4 may be provided in plurality, and may be, for example, a pressure sensor or a vibrator. For example, when the electronic elements S1-S4 are pressure sensors, it is possible to sense the pressure applied from the user's sole. As another example, when the electronic devices S1 - S4 are vibrators, vibration stimulation may be applied to the sole of the user's foot. Hereinafter, the electronic elements S1 - S4 will be described based on the pressure sensor, but it should be noted that the types of the electronic elements are not limited.

A support layer for the smart insole (hereinafter, referred to as a 'support layer') may be provided in the insole I. For example, the support layer is provided inside the insole I, and the plurality of pressure sensors S1-S4 are distributed in the support layer to measure pressures applied from different parts of the sole. For example, the first to third pressure sensors S1-S3 may measure the pressure applied from the user's forefoot, and the fourth pressure sensor S4 may measure the pressure applied from the user's rearfoot. Measurable.

The support layer includes a body layer (P), a connection layer (1) extending from the body layer (P), and a connection pad (11) provided at an end of the connection layer (1) spaced apart from the body layer (P) may include

The body layer P may be composed of three layers. The body layer P may include a lower PET (FPCB), a spacer, and an upper PET (FPCB). The pressure sensor includes two layers spaced apart from each other, and detects pressure by measuring the force acting between the two layers. The lower PET of the body layer (P) includes a line extending from the lower layer of the two layers constituting the pressure sensor, and the upper PET of the body layer (P) extends from the upper layer of the two layers constituting the pressure sensor It may include a line that becomes The spacer of the body layer P may assist the lower PET and the upper PET of the body layer P to be spaced apart from each other, and may prevent the lower PET and the upper PET from contacting and interfering with each other. The line provided in the lower PET of the body layer P and the line provided in the upper PET may be connected to each other in a region adjacent to the connection layer 1 .

The connection layer 1 may extend from the body layer P. Unlike the body layer P, the connection layer 1 may consist of one layer. The connection layer 1 may have a shape extending from any one of the lower PET and upper PET layers of the body layer P, for example. An integrated line in which the line provided in the lower PET of the body layer P and the line provided in the upper PET are connected to each other may extend along the connection layer 1 , and an end may be connected to the connection pad 11 .

The connection pad 11 may electrically connect the integrated line to the control unit C. The controller C may receive pressure information sensed from the plurality of pressure sensors S1-S4. The controller C may have a relatively larger size than the pressure sensors S1-S4, and may be mounted on a midsole (not shown) or a back-counter.

The connection layer 1 includes a distal part 12 including one end spaced apart from the body layer P, and the other end abutting the body layer P and extending in a first direction from the body layer P and distal It may include a proximal part 15 positioned at a different height from the part 12 , and connecting

parts

13 , 14 connecting the distal part 12 and the proximal part 15 .

The connection layer 1 may have an approximately 'L' shape when viewed in a direction perpendicular to the upper surface of the proximal part 15 . In the narrow space inside the shoe, securing a gap between the body layer (P) and the control unit (C) is limited. By designing the support layer to have an approximately 'L' shape in the shape of the connection layer 1, the length of the connection layer 1 can be formed to be long in a limited and narrow space. Due to this structure, even if relative movement and/or distortion occurs between the body layer P and the control unit C, the load and torsional force applied to the connection layer 1 may be reduced. As a result, the durability of the connection layer 1 can be improved.

Also, in the case of the connection layer 1 , the proximal part 15 and the distal part 12 may have a height difference from each other. For example, the distal part 12 may be located at a lower elevation than the proximal part 15 . According to this structure, the length of the connection layer 1 can be formed long in a limited and narrow space. Due to this structure, even if relative movement and/or distortion occurs between the body layer P and the control unit C, the load and torsional force applied to the connection layer 1 may be reduced. As a result, the durability of the connection layer 1 can be improved.

3 is a perspective view of a support layer for a smart insole according to an embodiment, FIG. 4 is a side view of a support layer for a smart insole according to an embodiment, and FIG. 5 is a plan view of a support layer for a smart insole according to an embodiment . In reality, the thickness of the connection layer 1 is formed to be thinner, but it should be noted that the thickness of the connection layer 1 and the body layer P are illustrated as the same in FIG. 3 for the sake of schematic drawing.

3 to 5 , the connection layer 1 extends from the body layer P and has an approximately 'L' shape when viewed in a plan view, and has an approximately 'L' shape when viewed from the front. . The proximal part 15 may be provided parallel to the body layer P, and the distal part 12 may be positioned below the body layer P. Since the connecting layer 1 is formed with a long length in a limited space, even if relative movement and/or torsion occurs between the connecting pad 11 and the body layer P, the amount of deformation of the connecting layer 1 per unit length is small. can

parts

13 and 14 include a horizontal part 14 provided at the same height as the proximal part 15 and extending from the proximal part 15 in a second direction intersecting the first direction, and one end of the horizontal part 14 ) and the other end may include a height adjustment part 13 connected to the distal part 12 . When the height adjustment part 13, which is a part whose height is changed among the

connection parts

13 and 14, is formed close to the distal part 12 instead of the proximal part 15, the part extending from the control part (not shown), that is, Since the length of the distal part 12 can be formed to be small, the size of the region in which the control unit (not shown) is mounted can be formed to be small. For example, assuming that the control unit (not shown) is mounted on the midsole, the midsole needs a groove for accommodating the control unit (not shown). As the length of the distal part 12 is formed to be small, the size of the groove itself is reduced. can be formed

The support layer may further include a protective layer 2 attached to one surface of the body layer P and the connection layer 1 . The protective layer 2 may be formed of an insulating material. The protective layer 2 may improve the durability of the body layer P and the connection layer 1 . The protective layer 2 may be made of a flexible material. The protective layer 2 may be attached to the upper surface or the lower surface of the body layer P and the connection layer 1 . 3 to 5 illustrate a state in which the protective layer 2 is attached to the upper surfaces of the body layer P and the connection layer 1 .

The protective layer 2 may include a main protective part 26 attached to one surface of the body layer P, and a connection protective part extending from the main protective part 26 and attached to one surface of the connection layer 1 . have. The connecting protection part comprises a first part 22 covering the distal part 12 , a second part 23 covering the height adjustment part 13 , and a third part covering the horizontal part 14 ( 24 ) and a fourth portion 25 covering the proximal part 15 . The protective layer 2 may be, for example, PET Film, FPCB (FCCL), Black shield tape, or acrylic tape.

The proximal part 15 extends from the body layer P in the first direction, and the width of the main protection part 26 may be greater than the width of the connection protection part in a direction perpendicular to the first direction. According to this shape, even if repeated deformation is applied to the connection layer 1, the protective layer 2 can be stably attached to the body layer P with a large area, so that the protective layer 2 and the body layer ( P) and the bonding stability of the connection layer 1 may be increased.

The edge portion of the main protection part 26 may be spaced apart from the edge portion of the body layer P by a distance D. Also, the connection protection part may be spaced apart from the edge portion of the connection layer 1 by an interval D. For example, the main protection part 26 and the connection protection part may be spaced apart from each other by 1 mm or more from the edge part of the body layer P and the edge part of the connection layer 1 . The spacing between the main protection part 26 and the connection protection part is shown to be the same for convenience, but it should be noted that the numerical values may be different from each other. In addition, it should be noted that, without a gap, the edge portions may be configured to coincide with each other.

The connection protection part of the protection layer 2 and the connection pad may be provided on the same side, for example, on the top side, of the distal part 12 of the connection layer 1 . In this case, the connection protection part may be spaced apart from the connection pad 11 by a distance D based on the longitudinal direction of the distal part 12 of the connection layer 1 . Since the connection pad 11 is fixed to the connector (not shown), movement may be limited, but the distal part 12 may be deformed because it is a part connected to the body layer P provided in the insole. Even if the distal part 12 is deformed in a direction of counterclockwise rotation about the y-axis, the connection protection part is spaced apart from the connection pad 11 , so that interference between the protection layer 2 and the connection pad 11 is prevented can be

Since the protective layer 2 is spaced apart from both edges of the distal part 12, even if the distal part 12 is deformed in the rotational direction about the x-axis, the protective layer 2 is separated from the distal part 12. can be prevented.
