[0016] Figure 1 A schematic diagram of the structure of a smart sofa provided by an embodiment of the present invention; Figure 2A partial cross-sectional view of a smart sofa provided in an embodiment of the present invention.

[0017] See also Figure 1 and Figure 2 An embodiment of the present invention provides a smart sofa, comprising: a back cushion 1, a base 2 and two armrests 3, the back cushion 1 is connected to the base 2, and each armrest 3 is located on two opposite sides of the base 2. In order to improve the applicability of the sofa, the smart sofa provided in this embodiment also includes: an extension pad 4, a controller 5 and a driving component.

[0018] The back cushion 1 is connected to the base 2 at an angle through the telescopic rod 6. The back cushion 1 and the base 2 are connected at a right angle or an obtuse angle to facilitate the user's sitting. The specific setting of the right angle connection or the obtuse angle connection at different angles can be set or adjusted according to the user's usage requirements.

[0019] A support plate 22 is provided inside the base 2, and the support plate 22 is parallel to the surface of the base 2, and is used to support the weight of the user; a support column 14 is provided inside the back cushion 1, and is used to resist the pressure exerted on the back cushion 1 when the user sits down. The support column 14 is connected to the support plate 22 through the telescopic rod 6, and the back cushion 1 and the base 2 are connected at an angle through the support plate 22, the telescopic rod 6 and the support column 14, or the surface of the back cushion 1 and the surface of the base 2 are located on the same plane.

[0020] When the back pad 1 and the base 2 are connected at an angle, the telescopic degree of the telescopic rod 6 remains unchanged, so that the support plate 22, the telescopic rod 6 and the support column 14 form a stable supporting component to avoid shaking when the user uses it.

[0021] The smart sofa provided in this embodiment can set the back cushion 1 and the base 2 at 180 degrees, that is, the sofa can be transformed into a bed for use. Specifically, by extending and retracting the telescopic rod 6, the back cushion 1 is controlled to rotate along the base 2 so that the surface of the back cushion 1 and the surface of the base 2 are located on the same plane.

[0022] When the user wants to transform the sofa into a bed, the user sends a command to the controller 5 through a mobile phone or a remote controller, and the controller 5 then sends the transformation command to the drive component connected to its output end, and the drive component is connected to the telescopic rod 6, and finally controls the locking of the telescopic rod 6, so that the back cushion 1 gradually rotates away from the base 2, and the purpose of transforming the sofa into a bed is achieved by the rotation of the back cushion 1 along the base 2. In this embodiment, the controller 5 can be a single-chip microcomputer, DSP, ARM or other chips with data processing functions, and this application does not make specific limitations.

[0023] Since the center of gravity of the sofa lies on the base 2 and the armrests 3 on both sides, that is, the stability of the sofa is maintained by the base 2 and the armrests 3, when the sofa is converted into a bed, the back cushion 1 is in a flat state, which will generate a downward force on one end of the base 2, making the base 2 likely to tip over. Therefore, in order to ensure the stability of the sofa when it is converted into a bed, in this embodiment, an auxiliary bracket 16 is provided on the back of the back cushion 1, and the auxiliary bracket 16 is connected to the back of the back cushion 1 through a connecting shaft; the connecting shaft is connected to the driving assembly, and the driving assembly controls the auxiliary bracket 16 to rotate along the connecting shaft.

[0024] When the controller 5 receives the user's transformation instruction, the controller 5 sends instructions to the driving assembly and the telescopic rod 6 at the same time, and controls the back cushion 1 to rotate along the base 2 through the telescopic rod 6, so that the sofa is transformed into a bed; at the same time, the driving assembly drives the connecting shaft to rotate, and controls the auxiliary bracket 16 to rotate with the connecting shaft as the fixed point, and stops after the auxiliary bracket 16 rotates to be perpendicular to the back cushion 1. In order to ensure stability, the length of the auxiliary bracket 16 is slightly larger than the distance between the back and the ground when the back cushion 1 is in a flat state.

[0025] Normally, when a user sits on the base 2 of the sofa, the calf is perpendicular to the ground, and when the user lies on the bed converted from the sofa, the legs also need to be parallel to the ground for the user to feel comfortable. However, given the size of the sofa, the total length of the back cushion 1 and the base 2 after laying flat is shorter than the height of the user, so it is necessary to provide a component on the sofa that allows the legs to be parallel to the ground.

[0026] In this embodiment, an extension pad 4 is provided at one end of the base 2, so that when the user lies on the transformed bed, the legs can be free, so that the user's entire body can be located on the bed to get a full rest. Therefore, in this embodiment, the extension pad 4 is connected to the end of the base 2 away from the back pad 1, that is, it contacts the legs when the user sits down. In the original state, that is, when it is a sofa, the surface of the extension pad 4 is perpendicular to the ground.

[0027] The extension pad 4 includes several extension parts 41 connected in sequence, and two adjacent extension parts 41 are movably connected and not fixed, so that the extension pad 4 can change its shape, so that the extension parts 41 can wrap the end of the base 2 away from the back pad 1. In the original state, the extension pad 4 uses the characteristic that two adjacent extension parts 41 can be connected at an angle to wrap one end of the base 2, so as to prevent the extension pad 4 from affecting the user's legs when the user sits on the sofa.

[0028] An actuator is provided inside the extension pad 4, and the actuator is used to drive the extension pad 4 to extend so that the surface of the extension pad 4 is on the same plane as the surface of the base 2. The actuator is connected to the driving component, and the driving component controls the extension pad 4 to extend with the portion connected to the base 2 as a fixed point according to the instruction of the controller, that is, the extension pad 4 is driven to extend and retract along the base 2, so that the free end of the extension pad 4 extends from a state perpendicular to the ground to a state parallel to the ground, so that the surface of the extension pad 4 is flush with the surface of the base 2, so that the user's legs are lifted off.

[0029] In this embodiment, the driving assembly is used to drive the telescopic rod 6, the connecting shaft and the actuator, and can be implemented by a motor in this embodiment. The driving assembly includes several motors, each of which is respectively connected to the telescopic rod 6, the connecting shaft and the actuator to drive the telescopic rod 6, the connecting shaft and the actuator to perform corresponding actions.

[0030] like Figure 4 As shown, Figure 4 The schematic diagram of the smart sofa provided in this embodiment transforming into a bed according to the user's instruction, when the user sits on the bed Figure 1 When the user wants to take a break on the sofa shown in the figure, he can use the control program pre-installed in the mobile phone or the remote control used with the sofa to send a change command. After receiving the change command, the controller 5 in the smart sofa sends a drive command to the corresponding motor of the drive component after a series of processing. One of the motors drives the telescopic rod 6 to start locking, so that the back cushion 1 gradually rotates downward and stops after the surface of the back cushion 1 is flush with the surface of the base 2; at the same time, another motor drives the connecting shaft to rotate, so that the auxiliary bracket 16 starts to rotate to a state perpendicular to the back cushion 1; another motor drives the actuator to unfold, and the extension pad 4 is unfolded from the state of wrapping one end of the base 2 to a straight state, so that the extension pad 4 is parallel to the ground and flush with the surface of the base 2. At this time, after completing a series of control processes, the smart sofa is transformed into a bed.

[0031] The above transformation process is carried out simultaneously, and in order to simplify the operation process of the smart sofa, when the transformation operation needs to be carried out simultaneously, the driving component can be set as a motor, and the telescopic rod 6, the connecting shaft and the actuator are driven by the motor to perform the corresponding operation, so that the structure of the smart sofa is simpler. When the user only wants to adjust the angle between the back cushion 1 and the base 2, or only wants to unfold the extension cushion 4 instead of converting it into a bed, the command sent by the user will only be sent by the controller 5 to the corresponding driving component. At this time, the driving component can be composed of multiple motors. The command can be sent to the corresponding motor according to which part of the sofa needs to be operated, so that the use of the smart sofa provided in this embodiment can achieve diversified characteristics.

[0032] Since the space occupied will increase when the smart sofa is converted into a bed, in order to ensure that the smart sofa has enough space for conversion, in this embodiment, when the user needs to convert, it is necessary to first determine the remaining space. The expansion operation is performed only when the remaining space is sufficient for the smart sofa to be unfolded, otherwise an alarm is issued to remind the user to clear the space.

[0033] To this end, a first distance sensor 42 for detecting the distance between the extension pad 4 and an obstacle is provided at the movable end of the extension pad 4, and a second distance sensor 15 for detecting the distance between the back pad 1 and an obstacle is provided at the upper end of the back of the back pad 1. The second distance sensor 15 is arranged on the lower side of the auxiliary bracket 16. The first distance sensor 42 and the second distance sensor 15 are respectively connected to the input end of the controller 5 arranged inside the base 2.

[0034] The controller 5 receives the user's conversion instruction and sends the instruction to the first distance sensor 42 and the second distance sensor 15 in advance for distance detection. The controller 5 pre-stores the space value required when the smart sofa is converted into a bed, which can be represented by distance, that is, the space required for the extension pad 4 to unfold and the space required for the back pad 1 to rotate and lay flat. The first distance sensor 42 and the second distance sensor 15 send the detected distance value to the controller 5, and the controller 5 compares the corresponding distance value with the pre-stored distance threshold. When the distance value monitored in real time is greater than or equal to the distance threshold, the operation of unfolding the smart sofa can continue to be executed, otherwise an alarm is issued to remind the user to clear the obstacle.

[0035] In order to realize the alarm operation, in this embodiment, an alarm 25 is provided on the side of the armrest 3, and the alarm 25 is connected to the output end of the controller 5. The alarm 25 is used to alarm according to the instruction of the controller 5. When the controller 5 determines that the current remaining space is insufficient for the smart sofa to unfold according to the detection results of the first distance sensor 42 and the second distance sensor 15, the controller 5 sends an alarm instruction to the alarm 25, and the alarm 25 starts the alarm operation to remind the user to take corresponding measures.

[0036] If the value detected by the second distance sensor 15 is less than the pre-stored distance threshold, the value detected by the first distance sensor 42 is much greater than the pre-stored distance threshold, and the value is greater than the sum of the distance required for the back cushion 1 to rotate in the current situation and the distance required for the extension cushion 4 to unfold, then the smart sofa can adjust its position by itself, that is, the smart sofa moves in the direction of the extension cushion 4, and the moving distance is the distance required for the back cushion 1 to rotate to a flat state. At this time, when the smart sofa is transformed into a bed, neither the extension cushion 4 nor the back cushion 1 will touch any obstacles.

[0037] In order to realize the function that the smart sofa can move by itself, in this embodiment, the smart sofa is equipped with wheels 8. Every two wheels 8 are located at the bottom of the same armrest 3, so the smart sofa includes four wheels 8. When the smart sofa does not need to be moved, in order to ensure the stability of the smart sofa, the four wheels 8 are respectively matched with locking mechanisms 9, and when the wheels 8 are not needed, the locking mechanisms 9 lock the wheels 8.

[0038] The wheel 8 is connected to the driving assembly, and the locking mechanism 9 is connected to the controller 5. When the smart sofa is in the process of being transformed into a bed and needs to move to adjust the front-to-back distance, the controller 5 sends an automatic adjustment instruction to the driving assembly. At this time, the driving assembly can be a separate motor. The motor drives the wheel 8 to move in the direction of the current larger distance value, so that the smart sofa can be transformed into a bed in sufficient space, thereby improving the convenience of operation.

[0039] A power module 7 is also provided in the base 2, and the power module 7 is respectively connected to the controller 5, the drive assembly, the first distance sensor 42 and the second distance sensor 15. The power module 7 is used to provide energy support for the smart sofa, including providing power for the controller 5, the drive assembly, the first distance sensor 42 and the second distance sensor 15.

[0040] After the smart sofa is transformed into a bed, the user needs to place the pillow again to rest comfortably. However, in this embodiment, in order to facilitate the user's rest, Figure 3 As shown, a pillow 12 is provided on top of the back cushion 1 .

[0041] When the smart sofa is in the original state, the pillow 12 is located on the top of the back cushion 1 to support the head of the user when the user is sitting. The two ends of the pillow 12 are connected to the side of the back cushion 1 through the corresponding rotating parts 11, and the other ends of the two rotating parts 11 are connected through the rotating shaft 17 located in the back cushion 1. The rotating parts 11 are used to support the pillow 12.

[0042] The rotating shaft 17 is connected to the driving assembly. When the back cushion 1 rotates along the base 2, the driving assembly drives the rotating 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 through the rotating member 11. When the smart sofa is transformed into a bed, the rotating shaft 17 is driven to rotate at the same time, thereby driving the rotating member 11 to rotate, so that the pillow 12 rotates to the surface of the back cushion 1, which is convenient for the user to use and improve the user experience.

[0043] In order to improve the comfort of the user sitting on the sofa, a cushion 21 is provided on the surface of the base 2. Since the smart sofa may be used by the elderly, if the elderly are unable to call for help in an emergency, their lives will be in danger. Therefore, in this embodiment, a physiological monitoring module 24 for monitoring the physiological parameters of the user is provided in the cushion 21, and the physiological monitoring module 24 is connected to the controller 5.

[0044] The physiological monitoring module 24 includes a heart rate sensor, a temperature sensor, a respiration sensor and a blood pressure sensor, which monitor the physiological signs of the user using the smart sofa in real time. When the data such as heart rate, body temperature, respiration and blood pressure are abnormal, the physiological monitoring module 24 sends the detection result to the controller 5, and the controller 5 sends a call for help to the alarm 25. At the same time, feedback information can also be sent to the main user's mobile phone to notify the main user to take rescue measures.

[0045] When users use a sofa or bed in winter or when the weather is cooler, their bodies will feel cold. In order to increase the warmth of the users, the smart sofa provided in this embodiment is provided with a first heating mechanism 23 in the base 2. The first heating mechanism 23 is located at the bottom of the seat cushion 21 and is used to heat the seat cushion 21; a second heating mechanism 13 is provided in the back cushion 1 and is used to heat the surface of the back cushion 1; the first heating mechanism 23 and the second heating mechanism 13 are respectively connected to the controller 5.

[0046] When the user needs to heat the smart sofa or the converted bed, a heating instruction is sent to the controller 5, and the controller 5 controls the first heating mechanism 23 and the second heating mechanism 13 to start, so as to heat the back cushion 1 and the seat cushion 21 on the base 2, so that the user can feel the warmth when using it, thereby improving the user experience.

[0047] It can be seen from the above technical scheme that the embodiment of the present invention provides a smart sofa, the back cushion 1 is connected to the base 2 at an angle through the telescopic rod 6, and the back cushion 1 is rotated along the base 2 by the telescopic rod 6, so that the surface of the back cushion 1 and the surface of the base 2 are located on the same plane. The extension pad 4 provided with an actuator is connected to one end of the base 2, and the actuator is connected to the driving component. The driving component drives the extension pad 4 to stretch out according to the instruction of the controller 5, so that the surface of the extension pad 4 and the surface of the base 2 are located on the same plane. The movable end of the extension pad 4 is provided with a first distance sensor 42 for detecting the distance between the extension pad 4 and the obstacle, and the back of the back cushion 1 is provided with a second distance sensor 15 for detecting the distance between the back cushion 1 and the obstacle. The first distance sensor 42 and the second distance sensor 15 send the detected distance value to the controller 5, and the controller 5 compares the corresponding distance value with the pre-stored distance threshold. When the distance value monitored in real time is greater than or equal to the distance threshold, the operation of unfolding the smart sofa can continue to be performed, otherwise an alarm is issued to remind the user to clear the obstacle. The smart sofa provided by the present invention can automatically detect the distance between the sofa body and the obstacle and automatically perform the transformation operation without the need for manual adjustment by the user, thereby making the operation more convenient and improving the user experience.
