[0002] Optical heart rate or blood sample detection has become popular on wearable devices, primarily smartwatches. Existing wearable device heart rate or blood sample detection solutions require the wearable device to be placed close to the skin to minimize interference from ambient light.

[0003] For glasses, when integrating optical components on the temples to realize heart rate detection or blood oxygen detection functions, the position where the temples fit the skin is easily affected by hair, thus affecting the detection results; and when integrating optical components on the nose pads to realize heart rate detection or blood oxygen detection functions, the nose pads integrated with optical components easily occupy the user's visual space, affecting the user's normal activities, and the nose pads often cannot be worn and fit well, and cannot always keep the nose pads close to the user's nose according to the shape of the nose of different users, which affects the heart rate and blood oxygen detection results and leads to inaccurate detection.

The nose pad is too large and easily occupies the user's visual space. In addition, since the nose pad cannot always fit closely to the user's nose according to the shape of the nose of different users, it affects the heart rate and blood oxygen detection results, resulting in inaccurate detection.

[0010] The nose pad shell is provided with a matching hole corresponding to the threaded connection hole;

[0011] The angle adjustment portion further includes a connecting bolt, which extends into the threaded hole section to be threadedly connected to the threaded hole section;

[0012] The nose pad end of the position adjustment portion extends into the connecting hole section and is fixedly connected to the connecting hole section.

[0013] In one embodiment, the frame end of the position adjustment portion includes a flat connecting end, and the flat connecting end is configured to be overlapped with the flat connecting end of the vital sign detection nose pad structure on the other side and connected to the frame.

[0014] In one embodiment, the photoelectric detection structure includes a main board, and a light-emitting portion and a photosensitive portion spaced apart on the main board, the light-emitting portion is used to emit light toward the nose wing, and the photosensitive portion is used to receive light reflected from the nose wing and generate the user's heart rate information and / or blood oxygen information.

[0015] In one embodiment, the housing is penetrated by a light-transmitting hole communicating with the accommodating cavity, and the light-transmitting hole forms the light-transmitting portion.

[0016] In one embodiment, the vital sign detection nose pad structure further includes a sealing portion, which is disposed in the light-transmitting hole and abuts against the hole wall of the light-transmitting hole, and the sealing portion is light-transmitting.

[0017] In one embodiment, the nose pad shell includes:

[0018] a nose pad upper shell, connecting the position adjustment portion and the angle adjustment portion; and

[0019] The nose pad lower shell is fixedly connected to the nose pad upper shell and encloses the nose pad upper shell to form the accommodating cavity. The nose pad lower shell is used to abut against the nose wing and is penetrated by the light-transmitting hole.

[0020] In one embodiment, the nose pad lower shell includes:

[0021] A nose pad inner shell, enclosing the nose pad upper shell to form the accommodating cavity, wherein the nose pad inner shell has a first hole extending through one end thereof away from the nose pad upper shell; and

[0022] A nose pad shell is sleeved on the outer side of the nose pad inner shell and is flexibly provided. The nose pad shell is provided with a second hole portion communicating with the first hole portion, and the nose pad shell is used to abut against the nose wing;

[0023] The first hole portion is connected to the second hole portion to form the light-transmitting hole.

Since the position adjustment part is flexibly set, after the deformation of the position adjustment part, the position adjustment part will not return to its original shape, but maintain the deformed shape setting. At this time, the photoelectric detection structure works and can send a photoelectric signal to the user's nose wing through the light-transmitting part, so as to detect the user's heart rate information and / or blood oxygen information according to the photoelectric signal.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] This utility model proposes a nose pad structure for vital sign detection. It aims to improve the existing solution of placing the vital sign detection component on the nose pad. The nose pad is too large and easily occupies the user's visual space. In addition, the nose pad cannot always fit closely to the user's nose according to the shape of the user's nose, which affects the heart rate and blood oxygen detection results and leads to inaccurate detection.

[0042] See also Figure 1-3 In one embodiment of the present invention, the vital sign detection nose pad structure 100 includes a nose pad shell 1, a vital sign detection structure 2 and a universal adjustment structure 3. The nose pad shell 1 has an accommodating cavity. The nose pad shell 1 is used to abut the nose wing, and a light-transmitting portion is provided at one end abutting the nose wing. The vital sign detection structure 2 includes a photoelectric detection structure, which is arranged in the accommodating cavity. The photoelectric detection structure is used to detect the user's heart rate information and / or blood oxygen information through the light-transmitting portion. The universal adjustment structure 3 includes a position adjustment portion 31 and an angle adjustment portion 32. The position adjustment portion 31 is flexibly arranged, and the angle adjustment portion 32 is connected to the nose pad shell 1 through a connecting hole; the frame end 312 of the position adjustment portion 31 is used to connect to the glasses frame, and the nose pad end 311 of the position adjustment portion 31 is connected to the angle adjustment portion 32 through the connecting hole. The position adjustment portion 31 drives the nose pad shell 1 to move in multiple directions, and the angle adjustment portion 32 drives the nose pad shell 1 to rotate in multiple directions.

[0043] In the technical solution of the present invention, the position adjustment unit 31 and the angle adjustment unit 32 first drive the nose pad shell 1 to move according to the shape of the nose wing of different users, thereby adjusting the position and angle of the nose pad shell 1 respectively, so that the nose pad shell 1 can closely fit the user's nose wing. Since the position adjustment unit 31 is flexible, after the position adjustment unit 31 is deformed, it will not return to its original shape, but will maintain the deformed shape. The photoelectric detection structure can emit a photoelectric signal to the user's nose wing through the light-transmitting portion to detect the user's heart rate information and / or blood oxygen information based on the photoelectric signal. With such a configuration, the position and angle of the nose pad shell 1 can be determined according to the user's nose wing shape and wearing habits through the adjustment of the position adjustment part 31 and the angle adjustment part 32, so that the vital sign detection nose pad structure 100 can adapt to a variety of nose wings of different shapes, and the nose pad shell 1 can always accurately abut and fit the nose wing, so as to ensure the accuracy of the vital sign detection structure 2 in detecting the user's heart rate information and / or blood oxygen information, and because the position adjustment part 31 and the nose pad shell 1 are both connected to the position connection part 32 through the connecting hole, while realizing the universal adjustment function of the nose pad structure 100, it also effectively reduces the volume of the position connection part 32, reduces the processing steps of the nose pad structure 100, and makes the position connection part 32 not occupy too much visual space of the user when the nose pad shell 1 abuts on the nose wing, thereby improving the user's usage experience.

[0044] To further enhance the wearer's experience and reduce the amount of space occupied by the wearer's eyes, in one embodiment of the present invention, the frame end 312 of the position adjustment portion 31 includes a flat connection end, which is configured to overlap and connect to the frame with the flat connection end of the other side nose pad structure 100. In this configuration, the two flat connection ends are stacked and placed within the frame. By optimizing the shape of the connection ends and setting the connection method, the size of the frame is reduced, thereby further reducing the space occupied by the wearer's eyes and ensuring the wearer's experience.

[0045] It should be noted that the present invention does not limit the specific structural forms of the position adjustment part 31 and the angle adjustment part 32. For example, in one embodiment of the present invention, the position adjustment part 31 can be set as a three-axis displacement part, and the angle adjustment part 32 can be set as a universal ball. The three-axis displacement part is used to connect the base of the universal ball and the frame, and the nose pad shell 1 is connected to the sphere of the universal ball. With such arrangement, when the user needs to adjust the position and angle of the nose pad shell 1 according to the shape of his or her nose wing, the three-axis displacement member moves to drive the universal ball and the nose pad shell 1 to move in multiple directions, thereby completing the adjustment of the position of the nose pad shell 1, and then, the universal ball rotates to drive the nose pad shell 1 to rotate along the axis extending in multiple directions, thereby completing the adjustment of the angle of the nose pad shell 1, and finally making the position and angle of the nose pad shell 1 adapt to the user's nose pad shape. At the same time, when the nose pad shell 1 abuts the user's nose wing, under the influence of gravity, the universal ball can further drive the nose pad shell 1 to rotate, so that the nose pad shell 1 can fit the user's nose wing more accurately, so as to ensure the accuracy of the vital sign detection structure 2 in detecting the user's heart rate information and / or blood oxygen information.

[0046] In another embodiment of the present invention, the position adjustment part 31 can be set as a steel wire rope, which is flexibly set, and the angle adjustment part 32 can be set as a rotating connector. The rotating connector rotating ring connects the nose pad shell 1 and the nose pad end 311 of the steel wire rope, and the frame end 312 of the steel wire rope is used to connect the glasses frame. With such a configuration, when the user needs to adjust the position and angle of the nose pad shell 1 according to the shape of his or her nose wing, the user can apply external force to the steel wire rope to drive the steel wire rope to deform, so as to drive the nose pad shell 1 to move. After the deformation of the steel wire rope, since the steel wire rope is flexibly set, the steel wire rope will not return to its original shape, but maintain the deformed shape setting, thereby completing the adjustment of the position of the nose pad shell 1. Afterwards, when the nose pad shell 1 abuts the user's nose wing, under the influence of gravity, the rotating connector will drive the nose pad shell 1 to rotate, so that the nose pad shell 1 can accurately fit the user's nose wing, thereby ensuring the accuracy of the vital sign detection structure 2 in detecting the user's heart rate information and / or blood oxygen information.

[0047] Of course, in other embodiments of the present invention, the position adjustment portion 31 and the angle adjustment portion 32 may also be configured as other structural forms, which can be selected according to actual needs during actual configuration.

[0048] In another embodiment of the present invention, the connection hole includes a threaded connection hole formed through the angle adjustment portion 32, and the nose pad housing 1 is provided with a mating hole corresponding to the threaded connection hole. The nose pad structure 100 further includes a connecting bolt 6, which passes through the mating hole to extend into the threaded connection hole and is threadedly engaged with the threaded connection hole, thereby fixedly connecting the position adjustment portion 31 to the angle adjustment portion 32. In this arrangement, the connecting bolt 6 passes through the mating hole to extend into the threaded connection hole and is threadedly engaged with the threaded connection hole. The connection between the nose pad housing 1 and the angle adjustment portion 32 via the connecting bolt 6 can ensure the stability of the connection between the nose pad housing 1 and the angle adjustment portion 32.

[0049] Specifically, in this embodiment, the angle adjustment portion 32 is connected to the nose pad housing 1 via a connecting bolt 6 .

[0050] When the angle adjustment portion 32 is connected to the nose pad housing 1 via the connecting bolt 6, in order to further increase the mobility of the nose pad housing 1, thereby improving the adaptability of the nose pad housing 1 and enabling the nose pad housing 1 to further adapt to more needs, in one embodiment of the present invention, the diameter of the connecting bolt 6 is A, and the diameter of the mating hole is B, where B>A. With this arrangement, when the diameter of the mating hole is larger than the diameter of the connecting bolt 6, the nose pad housing 1 can rotate relative to the connecting bolt 6 along its axially extending axis. This allows the nose pad housing 1 to further adapt to the wearer's needs after adjusting its position and angle, thereby making the nose pad structure 100 more capable of meeting the wearer's needs and expanding its scope of application.

[0051] Of course, it should be noted that in order to avoid the difference between the aperture of the mating hole and the diameter of the connecting bolt 6 being too large, which causes the connection between the nose pad shell 1 and the angle adjustment part 32 to become loose, and instead causes the nose pad structure 100 to be unable to meet the normal use needs of the wearer, in another embodiment of the present utility model, it is necessary to further limit the aperture of the mating hole and the diameter of the connecting bolt 6. Specifically, in this embodiment, the diameter of the connecting bolt 6 is A, the aperture of the mating hole is B, and A<B<1.1A.

[0052] In addition, in order to ensure that the photoelectric detection structure can detect the user's heart rate information and / or blood oxygen information smoothly through photoelectric detection, in one embodiment of the present invention, the photoelectric detection structure includes a main board 21, and a light-emitting portion 22 and a photosensitive portion 23 spaced apart on the main board 21. The light-emitting portion 22 is used to emit light to the nose wing, and the photosensitive portion 23 is used to receive the light reflected from the nose wing and generate the user's heart rate information and / or blood oxygen information. Specifically, in this embodiment, the light-emitting portion 22 first emits light to the user's nose wing through the light-transmitting portion. The light is irradiated on the user's nose wing, and in the blood vessels inside the human tissue, the light is reflected by hemoglobin. Part of the reflected light is reflected to the photosensitive portion 23 and received by the photosensitive portion 23. The photosensitive portion 23 can generate the user's heart rate information and / or blood oxygen information based on the reflected light.

[0053] Of course, to ensure the normal operation of the light emitting unit 22 and the light sensing unit 23 , the light emitting unit 22 and the light sensing unit 23 are both electrically connected to the mainboard 21 .

[0054] In an embodiment of the present invention, the light emitting portion 22 may be configured as a light emitting diode, and the light sensing portion 23 may be configured as a photosensitive diode.

[0055] It should also be noted that the present invention does not limit the specific type of light emitted by the light-emitting portion 22. In one embodiment of the present invention, the light-emitting portion 22 can emit red light; in another embodiment of the present invention, the light-emitting portion 22 can emit green light; in yet another embodiment of the present invention, the light-emitting portion 22 can also emit infrared light.

[0056] In other embodiments of the present invention, the light emitting portion 22 may also emit a mixture of at least two of red light, green light, and infrared light, which may be selected according to actual needs during actual configuration.

[0057] Furthermore, to ensure that the light emitted by the photoelectric detection structure can successfully illuminate the user's nose, in one embodiment of the present invention, the housing is provided with a light-transmitting hole 11 that communicates with the accommodating cavity, and light-transmitting hole 11 forms a light-transmitting portion. This arrangement allows the light emitted by the photoelectric detection structure to pass through light-transmitting hole 11 and directly illuminate the user's nose, thereby ensuring the accuracy of the vital sign detection nose pad structure 100 in detecting the user's heart rate information and / or blood oxygen information.

[0058] It should be considered that when a light-transmitting hole 11 is provided, dust or debris from the outside may enter the accommodating cavity through the light-transmitting hole 11, and may even cover the photoelectric detection structure, resulting in obstruction of the light emitted by the photoelectric detection structure. Therefore, in a further embodiment of the present invention, the vital sign detection nose pad structure 100 also includes a sealing portion 4, which is provided in the light-transmitting hole 11 and abuts against the hole wall of the light-transmitting hole 11, and the sealing portion 4 is light-transmitting. With such a setting, the light emitted by the photoelectric detection structure can first be irradiated onto the sealing portion 4, and since the sealing portion 4 is light-transmitting, the light can pass through the sealing portion 4 and irradiate the nose wing of the user, and the setting of the sealing portion 4 can seal the light-transmitting hole 11 to isolate the accommodating cavity from the outside, and prevent dust or debris from the outside from entering the accommodating cavity and affecting the normal operation of the photoelectric detection structure.

[0059] It can be understood that the present invention does not limit the material of the sealing part 4. In one embodiment of the present invention, the material of the sealing part 4 can be set to glass; in another embodiment of the present invention, the material of the sealing part 4 can also be set to transparent resin, or other light-transmitting materials. In actual setting, it can be selected according to needs.

[0060] Furthermore, since the photoelectric detection structure is installed in the accommodating cavity, in order to facilitate the installation of the photoelectric detection structure during the manufacturing process, in one embodiment of the present invention, the nose pad shell 1 includes a nose pad upper shell 12 and a nose pad lower shell 13. The nose pad upper shell 12 is connected to the position adjustment part 31 and the angle adjustment part 32. The nose pad lower shell 13 is fixedly connected to the nose pad upper shell 12 and encloses the accommodating cavity with the nose pad upper shell 12. The nose pad lower shell 13 is used to abut the nose wing and is penetrated by a light-transmitting hole 11. In this way, the photoelectric detection structure is first installed in the inner cavity of the nose pad lower shell 13, and then the nose pad upper shell 12 and the nose pad lower shell 13 are connected to each other to enclose and form an accommodating cavity, so that the photoelectric detection structure is in the accommodating cavity, and the photoelectric detection structure is sealed to ensure the working environment of the photoelectric detection structure.

[0061] Of course, in another embodiment of the present invention, the photoelectric detection structure can also be first installed in the inner cavity of the nose pad upper shell 12, and then the nose pad upper shell 12 and the nose pad lower shell 13 are connected. The present invention does not limit this.

[0062] In a further embodiment of the present invention, to ensure the stability of the installation of the photoelectric detection structure, a support platform 5 is provided within the accommodating cavity. The support platform 5 is fixedly connected to the photoelectric detection structure to support the photoelectric detection structure. The provision of the support platform 5 can provide an installation foundation for the installation of the photoelectric detection structure, thereby ensuring the stability of the installation of the photoelectric detection structure.

[0063] Of course, the present invention does not limit the specific structural form of the supporting platform 5. In one embodiment of the present invention, the supporting platform 5 may include a plurality of spaced-apart bosses, and the plurality of bosses are jointly connected to the photoelectric detection structure, thereby ensuring the stability of the support for the photoelectric detection structure.

[0064] In another embodiment of the present invention, the supporting platform 5 can also be arranged in a ring shape and fixedly connected to the periphery of one end face of the photoelectric detection structure. In this way, when the supporting platform 5 carries the photoelectric detection structure, it can prevent the photoelectric detection structure from positional displacement and angular displacement, and also ensure the stability of the support for the photoelectric detection structure.

[0065] Furthermore, in order to prevent the photoelectric detection structure from detaching from the supporting platform 5 when the user uses the vital sign detection nose pad structure 100, the supporting platform 5 is fixedly connected to the photoelectric detection structure. The present invention also does not limit the specific connection form between the supporting platform 5 and the photoelectric detection structure. In one embodiment of the present invention, the supporting platform 5 and the photoelectric detection structure are connected by bonding; in another embodiment of the present invention, the supporting platform 5 and the photoelectric detection structure are welded.

[0066] In other embodiments of the present invention, the supporting platform 5 and the photoelectric detection structure may also be connected by snap-fit connection, threaded connection, or other connection forms, and the present invention does not impose any restrictions on this.

[0067] Specifically, in this embodiment, the supporting platform 5 is provided on the lower shell 13 of the nose pad, and the photoelectric detection structure is installed in the inner cavity of the lower shell 13 of the nose pad.

[0068] It should be noted that when the nose pad upper shell 12 and the nose pad lower shell 13 are connected to each other, if there is a position deviation between the two, the accommodating cavity will not be sealed, thereby communicating with the outside world, which will affect the normal operation of the photoelectric detection structure. Therefore, in order to ensure the accuracy of the relative position of the nose pad upper shell 12 and the nose pad lower shell 13 when connected, in one embodiment of the present invention, the vital sign detection nose pad structure 100 also includes a positioning structure, which includes a positioning part and a matching part. Among the positioning part and the matching part, one is provided on the nose pad upper shell 12 and the other is provided on the nose pad lower shell 13. The positioning part and the matching part are used to locate the relative position of the nose pad upper shell 12 and the nose pad lower shell 13. With such an arrangement, before connecting the nose pad upper shell 12 and the nose pad lower shell 13, it is first necessary to make the positioning part and the matching part cooperate with each other to determine the relative position of the nose pad upper shell 12 and the nose pad lower shell 13, so as to ensure the accuracy of the connection position of the nose pad upper shell 12 and the nose pad lower shell 13, thereby ensuring the sealing effect of the accommodating cavity.

[0069] It can be understood that the present invention does not limit the specific structural forms of the positioning part and the matching part. In one embodiment of the present invention, the positioning part can be set as a positioning pin, and the matching part can be set as a matching groove. In this way, before the nose pad upper shell 12 is connected to the nose pad lower shell 13, it is necessary to first extend the positioning pin into the matching groove to complete the positioning of the nose pad upper shell 12 and the nose pad lower shell 13, and then connect the nose pad upper shell 12 and the nose pad lower shell 13 to ensure the accuracy of the connection position.

[0070] In another embodiment of the present invention, the positioning portion can also be set as a positioning baffle, and the matching portion can be set as a matching plate. Before the nose pad upper shell 12 is connected to the nose pad lower shell 13, it is necessary to first make the positioning baffle abut against the matching plate to complete the positioning of the nose pad upper shell 12 and the nose pad lower shell 13, and then connect the nose pad upper shell 12 and the nose pad lower shell 13 to ensure the accuracy of the connection position.

[0071] It should be noted that, since the lower shell 13 of the nose pad is used to abut the nose wing, in order to improve the user experience when using the nose pad structure 100 for vital sign detection and enhance the user's comfort, in one embodiment of the present invention, the lower shell 13 of the nose pad also includes a nose pad inner shell 131 and a nose pad outer shell 132. The nose pad inner shell 131 and the nose pad upper shell 12 are enclosed to form a accommodating cavity. The end of the nose pad inner shell 131 away from the nose pad upper shell 12 is penetrated by a first hole portion 111, and the nose pad outer shell 132 is sleeved on the outside of the nose pad inner shell 131 and is flexibly arranged. The nose pad outer shell 132 is penetrated by a second hole portion 112 connected to the first hole portion 111. The nose pad outer shell 132 is used to abut the nose wing, and the first hole portion 111 is connected to the second hole portion 112 to form a light-transmitting hole 11. With such a configuration, when the user uses the vital sign detection nose pad structure 100, the nose pad shell 132 can abut against the user's nose wing. At this time, the nose pad shell 132 will undergo elastic deformation under the action of pressure, thereby providing a buffer for the user when using the vital sign detection nose pad structure 100, and can better fit the surface shape of the user's nose wing, thereby enhancing the user's comfort.

[0072] In a further embodiment of the present invention, the sealing portion 4 is disposed in the first hole portion 111 and abuts against a side wall of the first hole portion 111 .

[0073] The present invention also provides a pair of glasses comprising a frame, a vital sign detection nose pad structure 100, and a cable. The specific structure of the vital sign detection nose pad structure 100 is described in the aforementioned embodiments. Since the present glasses utilize all of the technical solutions of all of the aforementioned embodiments, they possess at least all of the beneficial effects brought about by the technical solutions of the aforementioned embodiments, and are not further detailed here. A processor structure is provided on the frame, and a cable electrically connects the vital sign detection structure 2 and the processor structure. The processor structure is configured to receive a user's heart rate information and / or blood oxygen information, and output the user's heart rate data and / or blood oxygen data based on the user's heart rate information and / or blood oxygen information.

[0074] In the technical solution of the present invention, the position adjustment part 31 and the angle adjustment part 32 first enable the nose pad shell 1 to move according to the nose wing shape of different users, so as to adjust the position and angle of the nose pad shell 1 respectively, so that the nose pad shell 1 can fit closely to the user's nose wing. At this time, the photoelectric detection structure works and can send a photoelectric signal to the user's nose wing through the light-transmitting part to detect the user's heart rate information and / or blood oxygen information based on the photoelectric signal. Then, the detected user's heart rate information and / or blood oxygen information is transmitted to the processor structure through a cable, so that the processor structure can output the user's heart rate data and / or blood oxygen data based on the user's heart rate information and / or blood oxygen information, thereby completing the detection of the user's heart rate and / or blood oxygen. With this arrangement, the detection structure is accurate and the detection is convenient.

[0075] In a further embodiment of the present invention, the glasses further include a protective cover, which is flexible and fits over the outer side of the cable. Because the protective cover is flexible, the protective cover does not affect the normal movement of the cable. Furthermore, the protective cover prevents damage to the cable from external influences, thereby extending the service life of the cable.

[0076] The above are merely exemplary embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
