Description

Ring-shaped biosignal detection device with step joint

[0001] The present invention relates to a ring-shaped biosignal detection device having a step joint, and more particularly, to a ring-shaped biosignal detection device having a step joint in the shape of steps on both sides of a top cover, and advantageous in tolerance management by overlapping one side and the other side of an outer ring with the step joint.

[0002] Electrocardiogram (ECG) monitoring devices are widely used in the clinical diagnosis of heart disease and can be used to diagnose conditions such as myocardial infarction and pulmonary embolism. In particular, people with or suspected of having heart disease need to be able to detect or receive early warning of sudden cardiac abnormalities.

[0003] Electrocardiogram (ECG) devices attach electrodes to the body to detect the minute electrical signals generated by the heartbeat. However, conventional ECG devices suffer from the problem of being uncomfortable for the examiner to wear due to the size of the electrodes.

[0004] Meanwhile, wearable devices are being used in a variety of ways to detect biosignals such as blood pressure. Most conventional wearable devices are worn on the wrist. However, this type of wearable device has limitations, such as low reliability of biosignal data, as the wearable device does not come into contact with any part of the body other than the wearer.

[0005] To address the low reliability of biosignal data in conventional wearable devices, a ring-shaped sensing device is being developed that can improve the reliability of biosignal data. Conventional ring-shaped sensing devices may include an inner ring, an outer ring, and a top cover, and can be manufactured by assembling various components.

[0006] However, conventional ring-type sensing devices are manufactured by assembling various components, making it difficult to manage tolerances between components. In particular, managing tolerances for the outer ring, which is joined to the outer surface of the inner ring, is difficult. This difficulty in tolerance management can lead to defective products during the manufacturing process.

[0007] The present invention is intended to solve the above-described problem, and more specifically, relates to a ring-shaped bio-signal detection device which is advantageous in tolerance management by having a step joint formed in a step shape on both sides of a top cover and by joining one side and the other side of an outer ring to overlap the step joint.

[0008] In order to solve the above-described problem, the present invention provides a ring-shaped biosignal detection device having a step joint, which is a ring-shaped detection device for collecting biosignals, comprising: an inner ring that comes into contact with a user's finger; an outer ring that is coupled to the outer side of the inner ring while leaving a predetermined section of the inner ring open; and a top cover that is coupled to the outer side of the inner ring while leaving the predetermined section open. When the outer ring and the top cover are coupled to the inner ring, both ends of the top cover overlap with the outer ring.

[0009] The top cover of the ring-shaped biosignal detection device having a step joint of the present invention for solving the above-described problem may include a main body portion extending to a first thickness, and step joints provided on both sides of the main body portion and extending to a second thickness.

[0010] In order to solve the above-described problem, the second thickness of the ring-shaped biosignal detection device having a step joint of the present invention is smaller than the first thickness, and a step step may be formed between the main body and the step joint.

[0011] When the outer ring and the top cover are combined with the inner ring of the ring-shaped bio-signal detection device having a step joint of the present invention to solve the above-described problem, one side and the other side of the outer ring can overlap the step joint of the top cover.

[0012] In order to solve the above-described problem, an adhesive may be applied to the portion where one side and the other side of the outer ring of the ring-shaped biosignal detection device equipped with a step joint of the present invention overlaps with the step joint of the top cover.

[0013] In order to solve the above-described problem, a waterproof resin may be applied between one side and the other side of the outer ring of the ring-shaped biosignal detection device having a step joint of the present invention and the main body of the top cover.

[0014] In order to solve the above-described problem, the direction in which the step protrusion of the ring-shaped bio-signal detection device equipped with the step joint of the present invention extends may be extended in a diagonal direction with respect to the first direction extending in a direction perpendicular to the circumferential direction in which the inner ring extends.

[0015] In order to solve the above-described problem, one end of the outer ring and the other end of the outer ring of the ring-shaped biosignal detection device equipped with a step joint of the present invention can extend in a diagonal direction with respect to a first direction extending in a direction perpendicular to the circumferential direction in which the inner ring extends.

[0016] The top cover of the ring-shaped bio-signal detection device having a step joint of the present invention for solving the above-described problem includes a main body portion extending to a first thickness, a first step joint portion provided on both sides of the main body portion and extending to a second thickness, and a second step joint portion provided on one or the other side of the first step joint portion and extending to a third thickness, wherein the second thickness may be smaller than the first thickness, and the third thickness may be smaller than the second thickness.

[0017] In order to solve the above-described problem, the outer ring of the ring-shaped bio-signal detection device having a step joint of the present invention may be made of a metal part, and the top cover may be made of an injection-molded part.

[0018] The present invention relates to a ring-shaped biosignal detection device having a step joint, which has a step joint in the shape of steps on both sides of a top cover, and has an advantage in tolerance management by overlapping one side and the other side of an outer ring with the step joint.

[0019] In addition, the present invention has the advantage of reducing the rate of occurrence of defective products as tolerance management becomes easier by overlapping one side and the other side of the outer ring with a step joint.

[0020] In addition, the present invention has an advantage in that the outer ring and the top cover can be firmly joined as the joint area where the outer ring and the top cover are joined by the step joint increases.

[0030] When a component is referred to as being "connected, coupled" to another component, it should be understood that while the component may be directly connected or coupled to the other component, there may also be a new component between the component and the other component. Conversely, when a component is referred to as being "directly connected" or "directly coupled" to another component, it should be understood that no new component exists between the component and the other component.

[0031] The terms "first," "second," etc., used herein may be used to describe various components, but the components should not be limited by the terms. The terms are used solely to distinguish one component from another.

[0032] The present invention relates to a ring-shaped biosignal detection device having a stepped joint, wherein the ring-shaped biosignal detection device has stepped joints formed in a step shape on both sides of a top cover, and wherein one side and the other side of an outer ring are joined to overlap the stepped joints, thereby facilitating tolerance management. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0033] Referring to FIG. 1, a ring-shaped biosignal detection device having a step joint according to an embodiment of the present invention includes an inner ring (110), an outer ring (130), and a top cover (140).

[0034] The inner ring (110) above is in contact with the user's finger. The inner ring (110) may be formed in a circular ring shape, and the user's finger may be inserted into the inner ring (110) formed in a circular ring shape.

[0035] Referring to Fig. 1, the outer ring (130) is coupled to the outer side of the inner ring (110), but is coupled in a state where a predetermined section (111) of the inner ring (110) is open. The outer ring (130) is formed in an arc shape and extends.

[0036] The above outer ring (130) is formed in an arc shape and is coupled to a portion of the outer side of the inner ring (110). The portion of the outer side of the inner ring (110) where the outer ring (130) is not coupled may be an open predetermined section (111). The top cover (140) may be coupled to the predetermined section (111).

[0037] The top cover (140) is coupled to the outer side of the inner ring (110), and can be coupled to the predetermined section (111). The top cover (140) is formed in an arc shape and extends, and the top cover (140) can be coupled to the predetermined section (111) on the outer side of the inner ring (110) where the outer ring (130) is not coupled.

[0038] When the top cover (140) is coupled to the outer side of the inner ring (110), the top cover (140) can be coupled to the outer ring (130) on the outer side of the inner ring (110). When the outer ring (130) and the top cover (140) are coupled to each other, the outer ring (130) and the top cover (140) form a shape of a closed circular ring on the outer side of the inner ring (110).

[0039] A ring-shaped biosignal detection device equipped with a step joint according to an embodiment of the present invention may further include a battery assay. The battery assay includes a substrate and a battery, and the battery assay is positioned between the inner ring (110) and the outer ring (130) and between the inner ring (110) and the top cover (140).

[0040] Specifically, after the battery assay is combined with the inner ring (110), the outer ring (130) and the top cover (140) can be combined to the outside of the inner ring (110) and the battery assay.

[0041] The substrate of the above battery assay may include a control unit and a sensor unit capable of measuring and collecting biosignals. The control unit and sensor unit of the substrate can collect a user's biosignal when the user's finger is inserted into the inner ring (110) and comes into contact with the inner ring (110).

[0042] The above substrate may be implemented as a PCB (Printed Circuit Board) substrate including a control unit, and the substrate may include various configurations for collecting a user's biosignals in addition to the PCB substrate.

[0043] The battery provided in the above battery assay may supply power to operate the ring-shaped detection device. Specifically, the battery may supply power to operate the substrate, and the control unit and sensor unit of the substrate may be operated through the battery.

[0044] According to an embodiment of the present invention, when the outer ring (130) and the top cover (140) are combined with the inner ring (110), both ends of the top cover (140) may overlap with the outer ring (130).

[0045] As described above, the outer ring (130) and the top cover (140) can be joined to each other on the outside of the inner ring (110). At this time, if the top cover (140) and the outer ring (130) do not overlap and are joined while one end and the other end of the outer ring (130) and the other end and one end of the top cover (140) are in contact, there is a problem in that it is difficult to manage the tolerance of the outer ring (130) and the top cover (140).

[0046] Specifically, when one end and the other end of the outer ring (130) and the other end and one end of the top cover (140) are in contact and joined, if the length of the outer ring (130) and the top cover (140) is manufactured to be smaller than the specified size, a gap may be created and the joining may not occur. In addition, if the length of the outer ring (130) and the top cover (140) is manufactured to be larger than the specified size, there is a risk that the joining may not occur due to insufficient space.

[0047] In order to solve such a problem, a ring-shaped biosignal detection device equipped with a step joint according to an embodiment of the present invention can be connected so that, when the outer ring (130) and the top cover (140) are connected to the inner ring (110), both ends of the top cover (140) overlap with the outer ring (130).

[0048] In order to overlap both ends of the top cover (140) with the outer ring (130), the top cover (140) may include a main body (150) and a step joint (160).

[0049] Referring to FIGS. 2 and 3, the main body (150) extends to a first thickness (151), and the main body (150) extends in an arc shape. The step joint (160) is provided on both sides of the main body (150) and extends to a second thickness (161).

[0050] According to an embodiment of the present invention, the second thickness (161) of the step joint (160) may be smaller than the first thickness (151) of the main body (150). As the second thickness (161) of the step joint (160) is smaller than the first thickness (151) of the main body (150), a step protrusion (162) may be formed between the main body (150) and the step joint (160).

[0051] Referring to FIG. 2, the lower surface of the main body (150) and the lower surface of the step joint (160) may be on the same circumferential line, and since the second thickness (161) of the step joint (160) is smaller than the first thickness (151) of the main body (150), the upper surface of the main body (150) is positioned higher than the upper surface of the step joint (160).

[0052] The above step (162) may be a step created by a height difference between the upper surface of the main body (150) and the upper surface of the step joint (160), and the above step (162) may be formed in a step shape.

[0053] Referring to FIGS. 4 and 5, when the outer ring (130) and the top cover (140) are combined with the inner ring (110), one side and the other side of the outer ring (130) may overlap the step joint (160) of the top cover (140).

[0054] Specifically, when the outer ring (130) and the top cover (140) are combined with the inner ring (110), one side and the other side of the outer ring (130) can be raised above the step joint (160) of the top cover (140), as shown in FIG. 6.

[0055] Here, after the outer ring (130) and the top cover (140) are combined, the upper surface of the outer ring (130) and the upper surface of the main body (150) can be arranged on the same circumferential line.

[0056] According to an embodiment of the present invention, an adhesive may be applied to the portion where one side and the other side of the outer ring (130) and the step joint (160) of the top cover (140) overlap.

[0057] Before one side and the other side of the outer ring (130) and the step joint (160) of the top cover (140) overlap, an adhesive may be applied to the step joint (160), and one side and the other side of the outer ring (130) and the step joint (160) of the top cover (140) may be joined through the adhesive.

[0058] The adhesive according to the embodiment of the present invention may be of various types as long as it can bond one side and the other side of the outer ring (130) and the step joint (160) of the top cover (140).

[0059] In this way, when the outer ring (130) and the top cover (140) are combined with the inner ring (110), there is an advantage in managing the length tolerance of the outer ring (130) as one side and the other side of the outer ring (130) overlap with the step joint (160) of the top cover (140).

[0060] Specifically, even if the length of the outer ring (130) is manufactured to be smaller than the specified size, the outer ring (130) and the top cover (140) can be joined through the step joint (160).

[0061] In addition, when the outer ring (130) and the top cover (140) are combined with the inner ring (110), one side and the other side of the outer ring (130) overlap with the step joint (160) of the top cover (140), thereby increasing the joint area of ​​the outer ring (130) and the top cover (140), and thereby making it possible to firmly combine the outer ring (130) and the top cover (140).

[0062] According to an embodiment of the present invention, the outer ring (130) may be formed of a metal part, and the top cover (140) may be formed of an injection-molded part. Specifically, the outer ring (130) may be formed of a metal material, and the top cover (140) may be formed of an injection-molded material, such as plastic.

[0063] According to an embodiment of the present invention, a step joint may be formed on the outer ring (130), but it may be easier to process the top cover (140) made of an injection molded part than to process the outer ring (130) made of a metal part. Therefore, it is preferable that the step joint (160) be provided on the top cover (140).

[0064] According to an embodiment of the present invention, a waterproof resin may be applied between one side and the other side of the outer ring (130) and the main body (150) of the top cover (140). When the outer ring (130) and the top cover (140) are coupled while the one side and the other side of the outer ring (130) overlap the step joint (160) of the top cover (140), a gap may be generated between the one side and the other side of the outer ring (130) and the main body (150) of the top cover (140).

[0065] In order to prevent water from entering the inner ring (110) through such a gap, a waterproof resin may be applied between one side and the other side of the outer ring (130) and the main body (150) of the top cover (140).

[0066] The waterproof resin according to an embodiment of the present invention may be made of various types as long as it can reinforce the gap that occurs between one side and the other side of the outer ring (130) and the main body (150) of the top cover (140).

[0067] Referring to FIG. 3, the direction in which the step (162) according to the embodiment of the present invention extends may be extended in a diagonal direction with respect to the first direction (113) that extends in a direction perpendicular to the circumferential direction (112) in which the inner ring (110) extends.

[0068] The circumferential direction (112) along which the inner ring (110) extends may be the same as the circumferential direction of the outer ring (130) extending in an arc shape and the circumferential direction of the top cover (140) extending in an arc shape. The circumferential direction (112) along which the inner ring (110) extends may be the circumferential direction (112) illustrated in FIG. 3, and the first direction (113) may be a direction perpendicular to the circumferential direction (112).

[0069] The direction in which the step (162) provided on the top cover (140) extends may be diagonal to the first direction (113). According to an embodiment of the present invention, the direction in which the step (162) extends may be parallel to the first direction (113).

[0070] However, if the direction in which the step jaw (162) extends is extended diagonally with respect to the first direction (113), the area of ​​the step joint (160) can be expanded. Specifically, referring to FIG. 3, the area of ​​the step joint (160) can be expanded when the direction in which the step jaw (162) extends is diagonal with respect to the first direction (113) compared to when the direction in which the step jaw (162) extends is parallel to the first direction (113).

[0071] As the area of ​​the step joint (160) increases, the contact area between one side and the other side of the outer ring (130) and the step joint (160) increases, thereby allowing the outer ring (130) and the top cover (140) to be firmly joined together.

[0072] Referring to FIG. 4, one end of the outer ring (130) and the other end of the outer ring (130) according to an embodiment of the present invention may extend in a diagonal direction with respect to a first direction (113) extending in a direction perpendicular to the circumferential direction (112) in which the inner ring (110) extends.

[0073] The circumferential direction (112) along which the inner ring (110) extends may be the same as the circumferential direction of the outer ring (130) extending in an arc shape and the circumferential direction of the top cover (140) extending in an arc shape. The circumferential direction (112) along which the inner ring (110) extends may be the circumferential direction (112) illustrated in FIG. 4, and the first direction (113) may be a direction perpendicular to the circumferential direction (112).

[0074] One end of the outer ring (130) and the other end of the outer ring (130) may be points of contact with the step (162) provided on the top cover (140). Therefore, one end of the outer ring (130) and the other end of the outer ring (130) may be formed in a shape corresponding to the step (162) extending in a diagonal direction with respect to the first direction (113).

[0075] Accordingly, one end of the outer ring (130) and the other end of the outer ring (130) may extend in a diagonal direction with respect to the first direction (113). However, the present invention is not limited thereto, and one end of the outer ring (130) and the other end of the outer ring (130) may extend in a direction parallel to the first direction (113).

[0076] Referring to Fig. 7, the step joint (160) according to an embodiment of the present invention may be formed of a plurality of step layers. The step joint (160) may be formed in a step shape forming a plurality of step protrusions.

[0077] Specifically, referring to FIG. 7, the top cover (140) according to an embodiment of the present invention may include the main body (150), the first step joint (171), and the second step joint (172).

[0078] The main body (150) extends to a first thickness (151), and the main body (150) extends in an arc shape. The first step joint (171) is provided on both sides of the main body (150) and extends to a second thickness, and the second step joint (172) is provided on one or the other side of the first step joint (171) and extends to a third thickness.

[0079] According to an embodiment of the present invention, the second thickness of the first step joint (171) may be smaller than the first thickness of the main body (150), and the third thickness of the second step joint (172) may be smaller than the second thickness.

[0080] Referring to Fig. 7, the lower surface of the main body (150), the lower surface of the first step joint (171), and the lower surface of the second step joint (172) may be on the same circumferential line. Since the second thickness of the first step joint (171) is smaller than the first thickness of the main body (150), and the third thickness of the second step joint (172) is smaller than the second thickness of the first step joint (171), the upper surface of the main body (150) is higher than the upper surface of the first step joint (171), and the upper surface of the first step joint (171) is disposed at a higher position than the upper surface of the second step joint (172).

[0081] At this time, two step ridges may be generated due to the height difference between the upper surface of the main body (150) and the upper surface of the first step joint (171), and the height difference between the upper surface of the first step joint (171) and the upper surface of the second step joint (172). The step ridges may be formed in the shape of multiple steps.

[0082] Referring to FIG. 7, when the first step joint (171) and the second step joint (172) are provided on the top cover (140), one end and the other end of the outer ring (130) can be formed in a shape that simultaneously contacts the first step joint (171) and the second step joint (172).

[0083] By providing multiple step joints in this way, the joint area between the outer ring (130) and the top cover (140) can be increased, thereby making it possible to firmly connect the outer ring (130) and the top cover (140).

[0084] In the above description, the top cover (140) is described as having two step joints, but is not limited thereto. The top cover (140) may also have two or more step joints.

[0085] The ring-shaped biosignal detection device equipped with a step joint according to the embodiment of the present invention described above has the following effects.

[0086] A ring-shaped biosignal detection device equipped with a step joint according to an embodiment of the present invention has a step joint formed in a step shape on both sides of a top cover, and has an advantage in tolerance management by overlapping one side and the other side of an outer ring with the step joint.

[0087] In addition, the ring-shaped biosignal detection device equipped with a step joint according to an embodiment of the present invention has the advantage of reducing the rate of occurrence of defective products as tolerance management becomes easier by jointing one side and the other side of the outer ring so as to overlap with the step joint.

[0088] A ring-shaped biosignal detection device equipped with a step joint according to an embodiment of the present invention has an advantage in that the outer ring and the top cover can be firmly joined as the joint area where the outer ring and the top cover are joined increases by the step joint.

[0089] While the present invention has been described with reference to the embodiments illustrated in the drawings, these are merely exemplary, and those skilled in the art will appreciate that various modifications and variations of the embodiments are possible. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the appended claims.
