    DETAILED DESCRIPTION OF THE EMBODIMENTS [0012] FIG 1 is a schematic diagram of a structure of an intelligent sofa provided according to an embodiment of this invention, and FIG. 2 is a topical sectional view of an intelligent sofa provided according to an embodiment of this invention.
    [0013] Referring to FIGS. 1 and 2, an intelligent sofa provided according to an embodiment of this invention includes: a back cushion 1, a pedestal 2 and two handrails 3, wherein the back cushion 1 is connected with the pedestal 2, and the handrails 3 are located on opposite both sides of the pedestal 2, respectively. In order to improve applicability of the sofa, the intelligent sofa provided according to this embodiment further includes: an extension pad 4, a controller 5 and a drive assembly.
    [0014] The back cushion 1 is angularly connected with the pedestal 2 via an expansion link 6, in that the back cushion 1 is connected with the pedestal 2 in a right angle or an obtuse angle to facilitate the user to sit. As for specific arrangement of right-angle or obtuse-angle connection in different angles, it can be set or adjusted as per user’s requirement for use.
    [0015] The pedestal 2 has an interior provided with a support plate 22 parallel with a surface of the pedestal 2, the support plate 22 being used for supporting weight of the user; and the back cushion 1 is provided with a support column 14 therein for resisting a pressure on the back cushion 1 generated by sitting of the user. The support column 14 is connected with the support plate 22 via the expansion link 6, such that the back cushion 1 is angularly connected with the pedestal 2 via the support plate 22, the expansion link 6 and the support column 14, or, a surface of the back cushion 1 is located on a same level as a surface of the pedestal 2.
    [0016] When the back cushion 1 is angularly connected with the pedestal 2, dilatation of the expansion link 6 remains unchanged, such that the support plate 22, the expansion link 6 and the support column 14 form a stable support component to prevent shake from being occurred in the user’s use.
    [0017] The intelligent sofa provided according to this embodiment can arrange the back cushion 1 and the pedestal 2 to be presented in 180°, that is, can transform the sofa to a bed for use. Specifically, the back cushion 1 is controlled to rotate along the pedestal 2 by expansion and retraction of the expansion link 6, such that the surface of the back cushion 1 is located on a same level as the surface of the pedestal 2.
    [0018] When being intended to transform the sofa to a bed for use, the user can send an instruction to the controller 5 by a mobile phone or a remote controller, and the controller 5 then sends a transformation instruction to the drive assembly connected with input ends of the controller, the drive assembly being connected with the expansion link 6. In this case, the controller finally controls the locking of the expansion link 6, such that the back cushion 1 gradually rotates in a direction away from the pedestal 2, thereby achieving the object of transforming the sofa to a bed by rotating the back cushion 1 along the pedestal 2. In this embodiment, the controller 5 can be other chip having data processing function, such as single chip microcomputer, DSP, ARM and so forth, which is not specifically defined in this application.
    [0019] The center of gravity of the sofa resides in the pedestal 2 and the handrails 3 on both sides thereof, that is, the sofa is maintained to be stable by the pedestal 2 and the handrails 3. When the sofa is transformed to a bed for use, the back cushion 1 presents a flat-laid state, which may generate a downward acting force on one end of the pedestal 2, such that the pedestal 2 may be possibly rolled over. Therefore, in order to ensure stability of the sofa when being transformed to a bed for use, in this embodiment, an auxiliary bracket 16 is provided on a back portion of the back cushion 1, and connected with the back portion of the back cushion 1 via a connecting shaft, the connecting shaft being connected with the drive assembly, by which the auxiliary bracket 16 is controlled to rotate along the connecting shaft.
    [0020] When receiving the transformation instruction from the user, the controller 5 sends an instruction to the drive assembly and the expansion link 6 simultaneously, and controls the back cushion 1 to rotate along the pedestal 2 via the expansion link 6, so as to transform the sofa to a bed. Meanwhile, the drive assembly drives the connecting shaft to rotate, and controls the auxiliary bracket 16 to rotate for the connecting shaft as a fixed point and not to stop until the auxiliary bracket 16 is perpendicular to the back cushion 1. Further, in order to ensure stability, the auxiliary bracket 16 has a length slightly greater than a distance between the back portion of the back cushion 1 and the ground where the back cushion 1 is in the flat-laid state.
    [0021] Usually, when the user sits on the pedestal 2 of the sofa, the user’s shins are in a state perpendicular to the ground, while when the user needs to lie on the bed transformed from the sofa, the user’s legs also need to be in a state parallel with the ground, in this case the user can achieve comfortable experience. In view of a volume of the sofa, a total length of the back cushion 1 and the pedestal 2 after being flat-laid would also be shorter than the user’s height, in this case a component for allowing legs to be in a state parallel with the ground is also required to be arranged on the sofa.
    [0022] In this embodiment, an extension pad 4 is provided on one end of the pedestal 2, such that the user can hold legs in the air when lying on the bed transformed from the sofa, in this case all of the user’s body can be on the bed to enjoy full rest. Therefore, in this embodiment, the extension pad 4 is connected with one end of the pedestal 2 away from the back cushion 1, that is, contacts the user’s legs when the user sits in the sofa. In an original state (that is, in a state of sofa), a surface of the extension pad 4 is in a state perpendicular to the ground.
    [0023] The extension pad 4 includes several extension portions 41 connected in sequence, with adjacent two extension portions 41 connected flexibly instead of fixedly, such that the extension pad 4 can be changed in shapes to facilitate the several extension portions 41 to envelop one end of the pedestal 2 away from the back cushion 1. Iii an original state, the extension pad 4 can envelope one end of the pedestal 2 by means of the feature that the adjacent two extension portions 41 can be angularly connected together, to prevent the influence in the user’s legs occurred by the extension pad 4 when the user sits in the sofa.
    [0024] The extension pad 4 is provided with an actuator therein for driving the extension pad 4 to extend, such that a surface of the extension pad 4 is located on a same level as the surface of the pedestal 2. The actuator is connected with the drive assembly, which controls the extension pad 4 to extend for a part of the extension pad 4 connected with the pedestal 2 as a fixed point by the actuator according to an instruction of the controller, that is, drives the extension pad 4 to expand and refract along the pedestal 2. In this case, the extension pad 4 has a free end extending from a state perpendicular to the ground to a state parallel with the ground, such that the surface of the extension pad 4 is level with the surface of the pedestal 2 to allow the user’s legs to be held in the air.
    [0025] hr this embodiment, the drive assembly is used for driving the expansion link 6, the connecting shaft and the actuator, which may be implemented using electrical motor in this embodiment. The drive assembly includes several electrical motors, each correspondingly connected with the expansion link 6, the connecting shaft and the actuator respectively to drive them to perform the corresponding actions.
    [0026] As illustrated in FIG. 4, FIG. 4 is a schematic diagram of the intelligent sofa provided according to this embodiment, which has been transformed to a bed according to user’s instruction. When being intended to have a rest while sitting in the sofa illustrated in FIG. 1, the user can send a transformation instruction using a control program pre-installed in a mobile phone or a remote controller matched with the sofa, and the controller 5 within the intelligent sofa sends a drive instruction to electrical motors corresponding to the drive assembly through a series of processing after receiving the transformation instruction. One of the electrical motors drives the expansion link 6 to start to be locked, such that the back cushion 1 gradually rotates downward and does not stop until the surface of the back cushion 1 is level with the surface of the pedestal 2. Meanwhile, another electrical motor drives the connecting shaft to rotate, such that the auxiliary bracket 16 starts to rotate to a state perpendicular to the back cushion 1. A yet another electrical motor drives the actuator to extend, thereby driving the extension pad 4 to extend from a state enveloping one end of the pedestal 2 to a flat state, such that the extension pad 4 is parallel with the ground and level with the surface of the pedestal 2. At this time, after the above series of control procedures are completed, the intelligent sofa is transformed to a state of bed.
    [0027] The above transformation procedures are performed simultaneously. Also, in order to simplify the operation procedures of the intelligent sofa, when the transformation operations are required to be performed simultaneously, the drive assembly can be arranged as an electrical motor, and the expansion link 6, the connecting shaft and the actuator are driven simultaneously by one electrical motor to perform the corresponding operations to simplify the structure of the intelligent sofa. Further, when the user is only intended to adjust an angle between the back cushion 1 and the pedestal 2, or only intended to extend the extension pad 4 instead of transforming the sofa to a bed, the instruction sent by the user would only be sent to the corresponding drive assembly by the controller 5. At this time, the drive assembly can consists of a plurality of the electrical motors, in that where any part of the sofa is required to be operated, the instruction would be sent to the corresponding electrical motor, such that use of the intelligent sofa provided according to this embodiment can be diversified.
    [0028] Since it would occupy more space when the intelligent sofa is transformed to a bed for use, in order to ensure there is a sufficient space to support the intelligent sofa to transform, a remained space is required to be determined first when the user needs such transformation in this embodiment. The extension operation can be performed only if the remained space is sufficient to support the intelligent sofa to extend, otherwise an alert would be issued to remind the user of clearing up the space.
    [0029] For this, a first distance sensor 42 for detecting a distance between the extension pad 4 and an obstacle is provided on a movable end of the extension pad 4, and a second distance sensor 15 for detecting a distance between the back cushion 1 and an obstacle is provided on an upper end of a back portion of the back cushion 1, wherein the second distance sensor 15 is arranged on a lower side of the auxiliary bracket 16, and the first distance sensor 42 and the second distance sensor 15 are connected with input ends of the controller 5 provided in an interior of the pedestal 2, respectively.
    [0030] The controller 5 receives the transformation instruction from the user, and sends the instruction to the first distance sensor 42 and the second distance sensor 15 in advance in order to detect the distance. The controller 5 pre-stores space values required for the transformation of the intelligent sofa to a bed, which can be presented by distance, that is, a space required for extension of the extension pad 4 and a space required for rotation and flat laying of the back cushion 1. The first distance sensor 42 and the second distance sensor 15 send the detected distance value to the controller 5, by which the corresponding distance value is compared with a pre-stored distance threshold value. Where the distance value monitored in real time is greater or equal to the distance threshold value, an operation of extending the intelligent sofa can be continued to perform, otherwise an alert would be issued to remind the user of clearing up the obstacle.
    [0031] In order to realize an alerting operation, in this embodiment, alerters 25 are provided on sides of the handrails 3 and connected with input ends of the controller 5 for alerting according to an instruction of the controller 5. When the controller 5 determines the current remained space is insufficient to support the extension of the intelligent sofa according to the detected result of the first distance sensor 42 and the second distance sensor 15, the controller 5 sends an alert instruction to the alerters 25, which initiate the alerting operation and remind the user of performing the corresponding operation.
    [0032] If the numerical value detected by the second distance sensor 15 is less than the pre-stored distance threshold value, and the numerical value detected by the first distance sensor 42 is far greater than the pre-stored distance threshold value and greater than a sum of a distance required for the rotation of the back cushion 1 in a current situation and a distance required for the extension of the extension pad 4, the intelligent sofa can adjust its position by itself, that is, the intelligent sofa moves in a direction of the extension pad 4 by a distance required for the rotation of the back cushion 1 to a flat-laid state. At this time, when the intelligent sofa is transformed to a bed, neither the extension pad 4 nor the back cushion 1 can contact the obstacle.
    [0033] In order to realize the self-movement function of the intelligent sofa, the intelligent sofa is equipped with wheels 8 in this embodiment, wherein every two of the wheels 8 are located on a bottom portion of a same handrail 3, in this case the intelligent sofa includes four wheels 8. Where the intelligent sofa is not required to move, in order to ensure stability of the intelligent sofa, the four wheels 8 are matched with locking mechanisms 9 respectively, by which the wheels 8 are locked in case of being unused.
    [0034] The wheels 8 are connected with the drive assembly, and the locking mechanisms 9 are connected with the controller 5. Where the intelligent sofa is required to move for adjusting a distance front and back by itself in the process of being transformed to a bed, the controller 5 sends a self-adjustment instruction to the drive assembly, which can be an additionally arranged electrical motor at this time. The electrical motor drives the wheels 8 to move in a direction of a greater current distance value, such that the intelligent sofa can be transformed to a bed within a sufficient space, thereby improving operational convenience.
    [0035] The pedestal 2 is further provided with a power supply module 7 therein, the power supply module 7 being connected with the controller 5, the drive assembly, the first distance sensor 42 and the second distance sensor 15. The power supply module 7 is used for supporting energy to the intelligent sofa, including supporting energy to the controller 5, the drive assembly, the first distance sensor 42, the second distance sensor 15, and so forth.
    [0036] After the intelligent sofa is transformed to a bed, the user needs to put a pillow again for comfortable rest. In this embodiment, in order to facilitate the user to rest, a pillow 12 is proved on a top portion of the back cushion 1 as illustrated in FIG. 3.
    [0037] When the intelligent sofa is in an original state, the pillow 12 is located on the top portion of the back cushion 1 for supporting the user’s head when the user is sitting. The pillow 12 has two ends connected with sides of the back cushion 1 via corresponding rotary members 11 respectively, and two rotary members 11 have other ends connected with each other via a revolving shaft 17 located within the back cushion 1, the rotary members 11 being used for supporting the pillow 12.
    [0038] The revolving shaft 17 is connected with the drive assembly, and when the back cushion 1 rotates along the pedestal 2, the drive assembly drives the revolving shaft 17 to rotate according to the instruction of the controller 5, so as to rotate the pillow 12 to the surface of the back cushion 1 via the rotary members 11. In the process of transforming the intelligent sofa to a bed, the revolving shaft 17 is driven to rotate simultaneously, then the rotary members 11 are driven to rotate, such that the pillow 12 rotates to the surface of the back cushion 1, thereby facilitating user’s use and improving user’s experience.
    [0039] In order to improve user’s degree of comfort for sitting in the sofa, a seat cushion 21 is provided on the surface of the pedestal 2. Further, there may be aged people using the intelligent sofa, and once some sudden situation occurred on the aged people who cannot call for help by himself, their lives may be in danger. Therefore in this embodiment, a physiological monitoring module 24 for monitoring physiological parameters of a user is provided within the seat cushion 21, which is connected with the controller 5.
    [0040] The physiological monitoring module 24 includes a heart rate sensor, a temperature sensor, a respiration sensor and a blood pressure sensor, wherein physiological signs of the user who uses the intelligent sofa are monitored in real time by the heart rate sensor and the respiration sensor. When data including heart rates, body temperature, respiration, blood pressures, and the like becomes abnormal, the physiological monitoring module 24 sends the detected result to the controller 5, which sends a call-for-help instruction to the alertors 25, and meanwhile can also send feedback information to a main user’s mobile phone, so as to notify the main user to take rescue measures.
    [0041] When using a sofa or bed in winter or in cool whether, the user may feel cold on body. In order to improve user’s degree of warmth, the intelligent sofa provided according to this embodiment provides: a first heating mechanism 23 within the pedestal 2, wherein the first heating mechanism 23 is located on a bottom portion of the seat cushion 21 for heating the seat cushion 21; and a second heating mechanism 13 within the back cushion 1 for heating the surface of the back cushion 1, the first heating mechanism 23 and the second heating mechanism 13 being connected with the controller 5, respectively.
    io [0042] When being intended to heat the intelligent sofa or a bed transformed therefrom, the user can send a heating instruction to the controller 5, by which the first heating mechanism 23 an the second heating mechanism 13 are controlled to be initiated to heat the back cushion 1 and the seat cushion 21 on the pedestal 2, such that the user can feel warm in use, thereby improving the user’s experience.
    [0043] As can be known from the above technical solutions, embodiments of this invention provide an intelligent sofa, wherein the back cushion 1 is angularly connected with the pedestal 2 via an expansion link 6, and enabled to rotate along the pedestal 2 by expansion and retraction of the expansion link 6, such that a surface of the back cushion 1 is located on a same level as a surface of the pedestal 2; an extension pad 4 provided with an actuator is connected with one end of the pedestal 2, the actuator being connected with the drive assembly, by which the extension pad 4 is driven to extend according to an instruction of the controller 5, such that a surface of the extension pad 4 is located on a same level as the surface of the pedestal 2. The extension pad 4 has a movable end provided with a first distance sensor 42 for detecting a distance between the extension pad 4 and an obstacle, and the back cushion 1 has a back portion provided with a second distance sensor 15 for detecting a distance between the back cushion 1 and an obstacle. The first distance sensor 42 and the second distance sensor 15 send the detected distance value to the controller, by which the corresponding distance value is compared with a pre-stored distance threshold value. Where the distance value monitored in real time is greater or equal to the distance threshold value, an operation of extending the intelligent sofa can be continued to perform, otherwise an alert would be issued to remind the user of clearing up the obstacle. The intelligent sofa provided according to this invention can detect a distance between the sofa body and the obstacle by itself, and can perform transforming operations by itself without further need of manual adjustment operation by the user, thereby simplifying operations and improving experience.
