Description

BACKGROUND

The disclosure relates to a bedding device, and more particularly to a pillow and a method for adjusting a height and surface form of the bedding device.

When people sleep in different postures, the contact area between the head and the pillow or bed is varying, so a pillow with an adjustable height or a mattress with an adjustable surface form according to different sleep positions may improve the sleep comfort of people. Conventional bedding devices cannot accurately determine the sleep positions of the human, and thus fails to change the surface forms thereof to adapt to the sleep positions of people.

SUMMARY

The disclosure provides a bedding device, for example, a pillow and/or a mattress, that accurately determines the sleep positions of a human and adjusts the surface form thereof according to the sleep positions.

The bedding device comprises:

• • at least one adjusting unit able to adjust a height of the bedding device;
  • at least one human measurement module comprising a measurement control module and a measurement execution module, the human measurement module able to measure a three-dimensional surface morphology of a human and/or a quilt covering the human, able to obtain a three-dimensional point cloud of the human and/or a point cloud of the quilt, is able to establish a three-dimensional model of the human and/or a three-dimensional model of the quilt, able to recognize each part of the human from the three-dimensional point cloud and/or the three-dimensional model, and able to judge a spatial position and/or posture of each part of the human;
  • at least one sleep position determining module able to determine a sleep position of the human based on the spatial position and/or posture of each part of the human; and
  • at least one form adjustment module able to control the at least one adjusting unit to adjust a surface form of the bedding device based on the sleep position of the human and/or the spatial position and/or posture of each part of the human.

When the bedding device comprises a plurality of adjusting units, the plurality of adjusting units is able to adjust the height of the bedding device independently. The plurality of adjusting units is arranged in an array. A support platform is arranged on the top of each adjusting unit. At least one support platform is disposed on the surface of the bedding device. A heating/cooling module able to change the temperature of the support platform is disposed on the support platform. Optionally, the cooling module is a semiconductor cooling module. A massage module in vibration and/or other forms is arranged on the support platform and/or the adjusting unit to massage the human.

Specifically, the bedding device comprises at least one human measurement module able to measure 3D surface morphology of the head, neck, trunk, limbs and/or a quilt covering the human to obtain a 3D point cloud. A 3D human model is built based on the point cloud. The spatial position and/or posture of the head, neck, trunk and limbs are determined based on the point cloud and/or the 3D human model.

The at least one sleep position determining module is able to determine the sleep position of the human based on the 3D spatial position and/or posture of the head, neck, trunk and limbs and figure out the morphology of the cervical spine, thoracic spine, lumbar spine, hip bones and limbs of the human.

The at least one form adjustment module is able to control the at least one adjusting unit to adjust the surface form of the bedding device based on the sleep position and/or the forms of the spine, hip bones and limbs, so as to enable people to sleep in a comfortable position.

The form adjustment module is able to control the adjusting units in an array to move according to a preset rule. The movement rule comprises information on the lifting height, speed, time and location of each adjusting unit. The adjusting unit array may undulate in a wave form. The adjusting units in contact with and adjacent to the human may move up and down to assist the human in turning over. The adjusting units selected may move up and down in cycles and/or the adjacent adjusting units may alternately move up and down in cycles to press/massage the human.

The human measurement module is able to detect whether the sleep position changes or not by making continuous measurement on the body form. When the human is changing its sleep position, the form adjustment module controls the adjusting units that will come into contact with the human in the turning over direction to move down, so as to reduce the resistance for turning over the human. For example, when the human turns over to the left side from a supine position, the adjusting units on the left side of the body which will come into contact with the body move down, so as to form a low-lying area for the body to turn over. When the sleep position is changed, the adjusting units in contact with the human adjust the body posture to the most comfortable state under the control of the form adjustment module. When the human remains motionless, the form adjustment module controls each adjusting unit to move up, so that the adjusting units that will not come into contact with the human are kept at their longest length, and those that will come into contact with the human are also kept at their longest length to keep the human in the most comfortable position, thus making it easier for the adjusting units to move down to assist in turning over.

The bedding device of the disclosure is initialized prior to use. During initialization, each adjusting unit is equal in height and remains unchanged. When the human is lying on the bedding device in the supine, lateral, prone and other positions, the human measurement module measures the human in different positions respectively to obtain the point clouds on the surface of the human in different positions, and to build a plurality of 3D human models in different positions. During initialization, the point cloud on the surface of the human in a standing position is measured to build a 3D model of the human in the standing position. The human measurement module calculates the dimensions of features comprising volume, length and perimeter of different parts of the human (such as shoulder width, waist circumference, arm length and leg length) based on the 3D human model.

When the bedding device is in use, the form adjustment module figures out the surface form of the bedding device based on the feature dimensions of the human to achieve the most comfortable state of the human in the current sleep position, calculate the height of each adjusting unit in contact with different parts of the human, and compare the calculated height with the real-time height of each adjusting unit to determine the direction and length of adjustment for each adjusting unit. In this way, the adjusting accuracy and speed of each adjusting unit is improved.

When the bedding device is in use, the human data obtained from initialization is compared with that measured in real time, comprising the comparison of the volume and circumference of each part of the human, so as to predict the surface form of the bedding device when the human is in the best sleep position, and to change the height of each adjusting unit accordingly.

When the bedding device is in use, the form adjustment module is able to control the adjusting units to keep the form of the trunk/spine/head/neck of the human closest to that in the standing position, especially to keep the form of the spine closest to that in the standing position.

The human measurement module is able to measure the surface form and/or position and/or posture of the human by 3D laser scanning and/or TOF and/or double-sided stereoscopic vision and/or structured light and/or ultrasonic measurement and/or other well-known methods to obtain 3D human data and build a 3D human model.

The bedding device of the disclosure overcomes the problem in the prior art that the supine and prone positions with the head tilting sideways cannot be determined, and can accurately determine the body posture and adjust its surface form accordingly, so that the human is always in a comfortable state.

DETAILED DESCRIPTION

To further illustrate, embodiments detailing a bedding device and a method for adjusting a height and surface form of the bedding device are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.

A bedding device of the disclosure comprises an adjusting unit as shown in FIG. 1 which is cylindrical and comprises a base 311 and a telescopic rod 312. The base is mounted on a baseplate. The telescopic rod is telescoped relative to the base, and the height of the telescopic rod is adjustable in a pneumatic, hydraulic, or mechanical way. A support platform 313, which is in the shape of round or polygon with a radius of less than 5 cm, in certain embodiments less than 2 cm, is disposed on the top of the telescopic rod. The support platform and the telescopic rod are connected fixedly or flexibly. In certain embodiments, the support platform is connected to the top end of the telescopic rod through a hinge 314 or a spring, and swings relative to the telescopic rod. In certain embodiments, the support platform is perpendicular to the telescopic rod when no external force is applied thereto. The lifting height difference of the adjusting unit is at least greater than 5 cm, in certain embodiments greater than 10 cm. A displacement measurement device, which is able to measure the displacement of the telescopic rod relative to the base and then obtain the height of the adjusting unit, is disposed in the adjusting unit. In certain embodiments, the adjusting unit is in the shape of a polygon prism. The adjusting unit comprises one or more support platforms, and two or more adjusting units share one support platform.

In FIG. 2, a plurality of adjusting units 310 are vertically arranged in an array on the baseplate 320. The array is arranged in a rectangular form or in other forms. A surface of the bedding device, such as a pillow surface or a bed surface, comprises a plurality of adjusting units, telescopic rods and support platforms. The height and form of the pillow/bed surface is changed by changing the height of the adjusting units at different positions. The adjacent support platforms are connected by elastic members. When the adjacent adjusting units are different in height, the adjacent support platforms are tensioned relative to each other to change the angle of inclination, so as to smooth the curved surface transition of the pillow surface or the bed surface. When the bedding device is in the form of a pillow, it only comprises one adjusting unit and one support platform.

In FIG. 3, the bedding device is in the form of a mattress, comprising at least one human measurement module 10 which comprises at least one measurement control module 11 and at least one measurement execution module. The measurement execution module comprises at least one camera 13 and at least one linear laser 12, as well as a servo mechanism and auxiliary circuits as required. The laser 12 and the camera 13 are connected to the measurement control module 11. The measurement execution module is arranged above or on the side of the bedding device. Linear laser beams emitted by the laser scans the human, and the camera takes laser spot pictures. The measurement control module 11 and the measurement execution module are able to measure various parts of the human, including but not limited to the head 21, the neck 23, the trunk 26 and the limbs, in a 3D laser scanning manner. The measurement control module can identify point clouds at the laser spots from the picture. The measurement execution module is driven by the servo mechanism to scan different parts of the human, and the measurement control module obtains the point clouds at different positions on the surface of the human based on the pictures of different positions and then generates a point cloud on the surface of the entire human, and identifies different parts (comprising the head, neck, trunk and limbs), spatial positions and postures of the human based on the features of the point cloud. The features of the point cloud comprise but are not limited to the range, curvature, gradient, density and spatial shape of the point cloud. The measurement control module generates a 3D human model based on the point cloud, and identifies different parts, spatial positions and positions of the human based on the 3D human model. The measurement control module is able to generate 3D models of the head, neck model and trunk based on the point cloud measured.

The measurement control module identifies the face, the lateral head and the posterior portion of the head according to the point cloud and/or model of the head, and determines the 3D spatial position and posture of the head based on the models of these parts and/or the head. The identification is achieved by identifying organs such as the nose, auricles, eyes and lips, and then determining the position and/or posture of the head. The identification is achieved by identifying the features of different curved surfaces of the point cloud and/or model, comprising but not limited to the size, curvature and shape. The identification is achieved by identifying the features of point distribution in the point cloud, comprising but not limited to the gradient, density and dispersion degree of the points. Because of the differences in the reflection of linear laser beam from skin and hairy parts, the different parts also have different distribution patterns of the point cloud. As the hair can absorb more laser beams, the point clouds at the hairy parts are sparse and discrete. According to the features of the point cloud, the hairy parts and skin are determined.

The measurement control module identifies the 3D form and/or position and/or posture of the trunk based on the point cloud and/or model of the trunk. The measurement control module identifies the position and posture of the shoulders and determines the position of the trunk based on the shoulders. When the human is covered with a quilt, the point cloud on the quilt surface at the trunk is obtained. Whether the trunk is in a supine/prone or lateral position is determined based on the form of the point cloud on the quilt surface. In the lateral position, the point cloud on the quilt surface, especially at the shoulders, is high in height and narrow in width, and the height is greater than the width. In the supine/prone position, the width of the point cloud on the quilt surface, especially at the shoulders, is greater than the height thereof, and the height is the vertical distance between the highest point of the point cloud and the bed surface. A curved surface model or a 3D model of the human/quilt surface is built based on the point clouds, and the posture of the trunk is determined based on the features of the curved surface or the 3D model.

The measurement control module identifies the 3D form and/or posture of the neck based on the point cloud and/or model of the neck, and determines the position and posture of the cervical spine. The measurement control module identifies the 3D form and/or position and/or posture of the limbs based on the point cloud and/or model of the limbs.

The bedding device comprises at least one sleep position determining module 15. The measurement control module transmits the 3D form, position and posture information of the human to the sleep position determining module. The sleep positions comprise the supine position with face up, the supine, lateral and prone positions with the head tilting sideways, and the prone position with face down. The sleep position determining module determines the sleep positions based on the positions of each part of the human. When the face/head is up, the body is in the supine position, as shown in FIGS. 3 and 4, i.e., a supine position with face up. When the head is tilted sideways, the body is in the lateral position (such as the body posture in FIG. 5), the supine position with the head tilting sideways (such as the body postures in FIGS. 6 and 7), and the prone position with the head tilting sideways (such as the body postures in FIGS. 8 and 9), and the sleep position needs to be determined in combination with the form of the body and/or neck. When no quilt is covered on the human, it is determined that the trunk is in a lateral, supine or prone position based on the form of the trunk and shoulders. If the human is covered with a thick quilt, it may be determined that the trunk is lying in a lateral or supine/prone position, but it is impossible to distinguish between the supine position and the prone position. The posture of the trunk needs to be further determined in combination with the form of the neck. When the head is tilted to the left side of the human, the sternocleidomastoid in the right neck is stretched to form a raised area in the neck connecting the clavicle of the trunk and the posterior portion of the ear. Because the head is tilted to the left side, the raised area is rotated towards the front of the trunk. At the same time, the sternocleidomastoid in the left neck contracts, and the splenius capitis and splenius cervicis in the posterior portion of the left neck also contract. There is no raised area in the posterior portion of the neck, but instead there is a slightly recessed area sloping from the occiput to the root of the left neck, and a large area of folds sloping from the occiput to the root of the left neck is formed on the skin of the area. When the head is tilted to the right side of the body, the sternocleidomastoid in the left neck is stretched to form a raised area in the neck facing forwards, and a slightly recessed area and skin folds which are oblique are formed at the posterior portion of the neck. When it is impossible to determine that the trunk is in the supine or prone position, the sleep position determining module may determine the orientation of the trunk based on the form of the neck. If it is detected that the head is tilted sideways and the trunk is not in the lateral position, and that there is a raised area in the neck connecting the trunk and the posterior position of the ear, the forebreast of the trunk is up, and the body is in the supine sleep position with the head tilting sideways. If there is no raised area in the neck and/or a large area of oblique skin folds and/or a slightly recessed area in the neck are detected, the back of the trunk is up, and the body is in the prone sleep position with the head tilting sideways.

The form adjustment module 17 receives the body model, position, posture and sleep position information transmitted from the measurement control module and the sleep position determining module, and determines the spatial relationship between each part of the body and each adjusting unit according to the projection of each part of the human on the surface of the bedding device, i.e., determine which adjusting units to support a specific part of the body and the height of each adjusting unit. According to the correspondence, the form adjustment module controls the adjusting units to change their height, so as to adjust the position and posture of each part of the human and keep the human in the best position.

When the bedding device is in the form of a pillow, the form adjustment module controls the adjusting units constituting a pillow surface to change their height and then to change the height of the pillow surface and/or the spatial form and angle of inclination of the pillow surface, so as to adjust the head to the most comfortable position or a preset position, or to make the cervical spine in the most suitable position. In certain embodiments, the pillow surface is adjusted to a position which is the most adapted to the natural curvature of the human cervical spine. When the body is in the lateral position, the cervical spine is adjusted to be on the symmetrical plane of the longitudinal center of the human, i.e., the cervical spine coincides with the central line of the body when viewing right behind the human.

When the bedding device is in the form of a mattress, the form adjustment module controls the adjusting units in contact with the body to change their height and then to change the curved surface form and convex-concave state of the bed surface, so as to adjust the spatial position and posture of the head, neck, trunk and limbs to a comfortable position or a preset position, or to make the human spine in the most suitable position. In certain embodiments, when the body is in the supine or prone position, each part of the human is adjusted so that the spine is in a position which is the most adopted to the natural curvature of the human spine. In certain embodiments, when the body is in the lateral position, the spine is adjusted to be on the symmetrical plane of the longitudinal center of the human, i.e., the spine coincides with the central line of the body when viewing right behind the human.

The adjusting unit array of the bedding device comprises one or more areas, and each area works independently. In certain embodiments, a pillow area is divided from the mattress. In certain embodiments, a double bed is divided into two single areas which are controlled separately.

When in use, the human measurement module continuously detects any changes in the body form, and the sleep position determining module continuously monitors any changes in the sleep position and/or body posture. When the change in the body posture is detected, the form adjustment module adjusts the position and posture of each part of the human till the human is in a preset state or the most comfortable state.

The measurement control module, through the driving control module, controls the laser and the camera and/or the camera accessory of the intelligent terminal to perform 3D scanning measurement on the human to obtain the point cloud on the body surface and generate a 3D human model. The measurement control module identifies each part of the human and determines the spatial position and posture of the head, neck, trunk and limbs. The measurement control module transmits the position and posture information of the human model and each part of the human to the sleep position determining module and the form adjustment module. The sleep position determining module determines the sleep position of the body according to the above information and transmits the information to the form adjustment module. The form adjustment module determines the correspondence between each part of the human and the adjusting unit according to the position and posture of the human, and determines the height and form of the bedding device surface when the body is in a comfortable position.
