Sleep is not only necessary to maintain human life, but it also plays a very important role in maintaining the daily life of humans.

As the quality of human life improves, the importance of sleep has also been emphasized. Various methods have been proposed to maintain the correct and comfortable sleep, and a variety of assistive devices have been developed and studied to help maintain a comfortable sleep. .

For this reason, the importance of a pillow, which is a necessity at the time of sleeping, increases, and various technologies for a pillow are being developed and commercialized. The present invention relates to a pillow which is a tool necessary for sleeping.

The pillow is designed to support the head at a constant height during sleep and relax the airways and tension on the cervical vertebrae and help smooth the circulation of blood supplied to the head. However, using a pillow that is not appropriate for you, When using a pillow, it is not only difficult to take a good night's sleep, but also the symptom of headache, cervical vertebra, and shoulder pain after awakening from sleep.

In particular, when the sleeping position is unconsciously generated, the pressure on the face, the neck, the shoulder, and the arm is applied due to a wrong sleeping position, the blood circulation is not smooth and edema occurs, and when the wrong sleeping posture is maintained for a long time, In addition to being a cause of various diseases such as snoring and apnea, the use of the right pillow and the importance of sleeping in the right posture are being recognized again.

The use of the right pillow can be achieved by purchasing a pillow suitable for the user's body, but the sleeping position, which is generated in the unconscious state during sleep, is difficult to recognize because it is difficult to recognize the sleeping pattern.

Accordingly, it is possible to identify various sleep patterns that occur during sleeping of a person using a pillow during sleep, and provide the sleep patterns to the sleepers, thereby allowing the user to recognize various sleep patterns generated during sleep, The invention of a smart pillow is being developed.

In this conventional example, Korean Patent Laid-Open No. 10-2010-18975 (published on Mar. 2, 2010) discloses a pillow with a built-in non-restrained sleep state determining device.

In the above-described conventional example, biometric information including pulse, respiration, body motion, snoring, and irregular heartbeat during sleeping pillow is detected through a sensor, the biometric signal detected by the sensor is filtered and amplified, And a controller for extracting a specific parameter from the detected bio-signal to provide the user's sleep state as a quantitative indicator.

Accordingly, the pillow user can adjust his / her life pattern by acquiring various kinds of biometric information that occurs during his / her sleep through such a conventional example.

Accordingly, it is possible to analyze the sleep pattern of the user by detecting the sleep state of the sleeping user, and to provide the information about the objective sleeping pattern based on the user's sleeping information, thereby positively managing the sleeping state of the user of the pillow Respectively.

However, a pressure sensor, a sound sensor, and a pressure sensor for acquiring sleeping information are installed inside the pillow body to sense the movement of the sleeping person, the reaction of the sleeping person, the direction of the sleeping face, etc. The pillow body having a constant cushion, The sensor and circuit boards installed therein are easily damaged, which is inconvenient when using the pillow, and has a disadvantage that the durability is poor.

In order to improve the disadvantages of the conventional well-being pillow system, the present inventor filed a supplementary application for a pillow for well-being with the patent application No. 10-2015-111832 filed on August 5, 2015.

The 'wellness pillow' of the inventor of the present invention, which has been supplemented by the present invention, improves the shape of the top surface of the pillow in direct contact with the body of the user of the pillow to facilitate understanding of the sleeping pattern of the pillow user, .

Further, when the pillow body made of a cushioning material is handled, various sensors and circuit boards installed therein are prevented from being deformed or damaged, thereby improving durability.

Through the above improvement, the inventive well-being pillow system has been able to be developed as a new product.

However, in the body pressure sensor which is installed in the left and right direction of the pillow inside the pillow body to sense the pressure of the sleeping person, some errors are generated in the sensing signal detecting the direction of the sleeping person during the sleep, The present invention has been made.

Hereinafter, a sensing structure of a pressure sensor for a pillow according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a front exterior appearance of a pillow 100 to which the present invention is applied, and FIG. 2 illustrates a backward separation state of a pillow to which a sensing structure according to the present invention is applied.

Referring to FIG. 1, the shape of the pillow body 10 will be briefly described. In the pillow body 10, as shown in the figure, a protruding portion 16 of a rod- And a plurality of protrusions are formed at predetermined intervals in the front-back direction of the top surface 11 of the main body 10.

Even if the body 10 of the elastic material is deformed by the head weight of the sleeping person, that is, the body pressure, the plurality of the protrusions 16 are provided with a predetermined gap between the plurality of protrusions to maintain air permeability, Effect. ≪ / RTI >

The main body 10 is formed such that the thickness of the central portion of the body 10 is smaller than the thickness of the left and right sides, and the upper surface 11 extending from the central portion to the left and right side edges is formed to have an oblique slope, I.e., the head of the user, to the occipital region 12.

That is, at the center rear side of the upper surface of the main body 10, the rear head portion of the sleeping person is positioned to form a rear head seating portion 12 having a spherical concave groove with a predetermined depth so as to take a comfortable sleep, A cervical spine receiving portion 13 is formed to support the cervical spine portion of the sleeping person to release tense muscles on the cervical spine and shoulder to prevent the occurrence of the neck disk, the snoring, and the headache.

In addition, on the left and right side edges of the upper surface of the main body 10, there are formed separation preventing projections 14 and 15 which are protruded somewhat higher than the upper surface and the upper surface is rounded to prevent a sleeping posture .

2, the structure of the body pressure sensing unit 30 embedded in the body of the pillow body 10 at the bottom surface 20 is illustrated as being detached.

A rectangular mounting groove 40 having a predetermined width and depth in the left and right longitudinal direction is formed on the bottom surface 20 of the main body 10 and a body pressure sensing sensing unit 30 is installed in the mounting groove 40. [ .

Particularly, the installation groove 40 has a structure in which the left and right sides are somewhat deeper than the central portion. The reason why the left and right sides of the installation groove 40 are formed slightly deeper than the central portion is that the body pressure detection The sensing sensitivity of the sensing unit 30 is prevented from varying with the height of the main body, thereby improving the body pressure sensing performance and accuracy.

The body pressure sensing sensing part 30 installed in the mounting groove 40 has a predetermined length of a circuit board 34 formed in a flat plate shape and a circuit board 34 fixed to the circuit board 34 A plurality of body pressure detecting sensors 32 integrally formed on the upper surface 11 of the main body and a pressure sensor 34 for receiving head pressure of a sleeping person applied on the upper surface 11 of the main body, And sensing plates (36, 37).

More specifically, the body pressure sensing unit 30 acquires sleep patterns such as a sleeping time, a sleeping depth, and the number of times of occurrence of a repetition occurrence, and transmits the sleep pattern to a user's portable smart device. And to acquire and provide sleep information so that sleep patterns can be analyzed through a dedicated program.

Therefore, a plurality of separate pressure-sensitive sensors 32 are provided along the installation groove so as to obtain the sleeping information according to the part where the head part of the sleeping person is located at the time of sleep and the direction of movement of the head at the time of the heading, And the plurality of pressure sensors 32 are integrally fixed on one circuit board 34. The pressure sensors 32 are installed in the mounting groove 40 formed on the bottom surface 20 of the main body, So that the horizontal state is maintained.

The body pressure detecting sensor 32 provided on the circuit board 34 installed on the inside of the mounting groove 40 so as to maintain a substantially horizontal state has a body pressure detecting sensor 32 provided on the upper surface 11 of the body, Since the center thickness of the pillow body 10 is formed to be slightly thinner than both the right and left thicknesses as described above, when the same body pressure is applied on the upper surface 11 of the body, The body pressure transmitted to the sensor 32 is changed, which may interfere with accurately grasping the sleeping information such as the accurate position of the sleeping position and the number of times of repetition.

The depth of the installation groove 40 is different from the center of the main body 10 and the right and left sides of the main body 10 in order to compensate for the difference in the body pressure due to the difference in thickness of the pillow body 10.

A deformation preventing member 50 having a predetermined thickness in the vertical direction with respect to the circuit board 34 is installed so as to prevent the circuit board 34 made of a straight shape from being broken by the right and left refractions after being installed inside the main body 10 of the elastic material do.

The deformation preventing member 50 has a structure in which the deformation preventing member 50 is inserted and fixed to the inside of the deformation preventing member mounting groove 45 formed in the longitudinal direction of the mounting groove 40 to vertically support one side of the circuit board 34, After the body pressure sensing unit 30 is assembled into the groove 40, a base plate 60 having a predetermined thickness is coupled to the bottom of the pillow, and then a pillow cover is wrapped around the pillow cover.

3 is a vertical sectional view and a partial enlarged view according to an assembled state in which the body pressure sensing sensing unit 30 is installed inside the installation groove 40 formed in the pillow body 10.

3, a plurality of pressure sensors 32 are disposed in a row on the circuit board 34. The pressure sensors 32 are arranged in a row along the longitudinal direction of the main body 10, So that the head position of the sleeping person can be grasped.

2, the bottom plate 60 of the flat plate is coupled to the bottom surface 20 of the main body 10, so that the main body 10 made of a cushioning material is inserted into the bottom surface 20 of the main body 10, And to prevent the body pressure sensing sensing unit 30, which is embedded in the body 10, from separating.

3, the base plate 60 is brought into contact with the bottom surface to keep the main body 10 in a horizontal state, and the circuit board 34, which is embedded in the mounting groove 40, The horizontal state is maintained while being supported on the upper surface of the bottom plate 60 and the plurality of pressure sensors 32 provided on the circuit board 34 are also installed horizontally by the horizontally installed circuit board 34 do.

However, the body pressure detecting sensor S1 located on the left and right sides of the main body 10 and the body pressure detecting sensor S2 located in the center of the main body 10 are different from the upper face 11 of the main body 10, Which may cause a difference in the body pressure sensing performance.

In order to compensate for this, as described above, the left and right thick portions of the main body 10 are formed so as to have a depth of the installation groove 40, The sensing pressure plate 37 on which the sensor pressing protrusion 38 is formed is positioned on the upper surface of the body pressure detecting sensor S1 located on the center side of the main body 10, And a pressure plate 36 is installed.

That is, a plate-type sensing platen 36 is provided on the upper surface of the body pressure sensing sensor S2, which is located at the center of the body 10 where the thickness of the body 10 is relatively thin and the body pressure sensing is advantageous, A body thickness difference or an inclination difference of the sensing pressure plate is formed on the upper surface of the body pressure sensing sensor S1 located on the right and left sides of the body 10 which is relatively thick due to a relatively large thickness of the body 10, In order to overcome the disadvantage of the pressure sensing due to the difference in height of the mounting plate 40, the sensor pressing protrusion 38 having a different height at the left and right sides is formed so that the sensing platen 37 is positioned higher, .

The sensing pressure plate 37 provided with the sensor pressing protrusions 38 provided on the right and left sides of the mounting groove 40 has a thickness corresponding to the difference in distance between the two pressure sensors, The sensor pressing projection 38a provided on the upper surface of the outermost body pressure detecting sensor is arranged in a direction opposite to the sensor pressing projection 38b provided on the upper surface of the body pressure detecting sensor in which the sensor pressing protrusion 38a is installed in the inner direction, So that compensation is performed according to the height difference between the inside and outside of the main body.
