The support column 14 is connected with the support plate 22 through the telescopic rod 6, and the back pad 1 and the base 2 are connected in an angle through the support plate 22, the telescopic rod 6 and the support column 14, or the surface of the back pad 1 and the surface of the base 2 are positioned on the same surface.
When the back pad 1 and the base 2 are connected in an angle, the expansion degree of the expansion link 6 is kept unchanged, so that the support plate 22, the expansion link 6 and the support column 14 form a stable support part, so that shaking is avoided when a user uses the back pad.
The intelligent sofa provided by the embodiment can be used by arranging the back cushion 1 and the base 2 at 180 degrees, namely, the sofa is changed into a bed for use. Specifically, the back pad 1 is controlled to rotate along the base 2 by the extension and contraction of the extension and contraction rod 6, so that the surface of the back pad 1 and the surface of the base 2 are positioned on the same plane.
When a user wants to change the sofa into a bed, the user sends an instruction to the controller 5 through the mobile phone or the remote controller, the controller 5 sends the change instruction to the driving component connected with the output end of the controller, the driving component is connected with the telescopic rod 6, and finally the locking of the telescopic rod 6 is controlled, so that the back cushion 1 gradually rotates in a direction away from the base 2, and the aim of changing the sofa into the bed is achieved through the rotation of the back cushion 1 along the base 2. In this embodiment, the controller 5 may be a single chip microcomputer, a DSP, an ARM, or other chips with data processing functions, which is not particularly limited in the present application.
Because the center of gravity of the sofa is located on the base 2 and the armrests 3 on two sides, namely, the base 2 and the armrests 3 keep the sofa stable, and when the sofa is changed into a bed for use, the back cushion 1 is in a flat state, a downward acting force can be generated on one end of the base 2, so that the base 2 can be laterally turned over. Therefore, in order to ensure the stability of the sofa when the sofa is converted into a bed, in this embodiment, the back of the back cushion 1 is provided with the auxiliary bracket 16, the auxiliary bracket 16 is connected with the back of the back cushion 1 through a connecting shaft, the connecting shaft is connected with a driving assembly, and the driving assembly controls the auxiliary bracket 16 to rotate along the connecting shaft.
When the controller 5 receives a conversion instruction of a user, the controller 5 simultaneously sends an instruction to the driving assembly and the telescopic rod 6, the telescopic rod 6 controls the back cushion 1 to rotate along the base 2 to convert the sofa into a bed, and meanwhile, the driving assembly drives the connecting shaft to rotate to control the auxiliary support 16 to rotate at a fixed point by taking the connecting shaft as a fixed point, and the auxiliary support 16 stops rotating until the auxiliary support 16 is vertical to the back cushion 1. In order to ensure stability, the length of the auxiliary support 16 is slightly greater than the distance between the back and the ground when the back pad 1 is in a flat state.
Typically, the user sits on the base 2 of the sofa with the lower leg portion in a position perpendicular to the ground, and when the user needs to lie on the bed formed by the conversion of the sofa, the leg portion needs to be parallel to the ground, so that the user experiences comfort. In view of the volume of the sofa, the overall length of the back cushion 1 and the base 2 after being laid is shorter than the height of the user, so that a component for the legs to be parallel to the ground needs to be arranged on the sofa.
In this embodiment, an extension pad 4 is provided at one end of the base 2, so that the legs can be emptied when the user lies on the converted bed, and the whole body of the user can be positioned on the bed, so that a sufficient rest can be obtained. Thus, in this embodiment, the extension pad 4 is connected to the end of the base 2 remote from the back pad 1, i.e. in contact with the legs when the user sits down. In the original state, i.e. sofa, the surface of the extension pad 4 is vertical to the ground.
The extension pad 4 comprises a plurality of extension portions 41 which are connected in sequence, and two adjacent extension portions 41 are movably connected and are not fixed, so that the extension pad 4 can change shape, and one end of the base 2 far away from the back pad 1 is conveniently wrapped by the plurality of extension portions 41. In the original state, the extension pad 4 wraps one end of the base 2 by utilizing the characteristic that two adjacent extension portions 41 can be connected in an angle, so that the extension pad 4 can not affect the legs of a user when the user sits on the sofa.
An actuating mechanism is arranged in the extension pad 4 and is used for driving the extension pad 4 to be unfolded, so that the surface of the extension pad 4 and the surface of the base 2 are positioned on the same surface. The actuating mechanism is connected with the driving component, the driving component controls the extension pad 4 to be unfolded at a fixed point by taking the part connected with the base 2 as a part connected with the base 2 through the actuating mechanism, namely, the extension pad 4 is driven to stretch along the base 2, so that the free end of the extension pad 4 stretches from a state vertical to the ground to a state parallel to the ground, the surface of the extension pad 4 is flush with the surface of the base 2, and the legs of a user are emptied.
In this embodiment, the driving component is used for driving the telescopic rod 6, the connecting shaft and the actuating mechanism, and in this embodiment, the driving component can be implemented by adopting a motor. The driving assembly comprises a plurality of motors, and each motor is correspondingly connected with the telescopic rod 6, the connecting shaft and the executing mechanism respectively so as to drive the telescopic rod 6, the connecting shaft and the executing mechanism to execute corresponding actions.
As shown in fig. 4, fig. 4 is a schematic diagram of the intelligent sofa according to the embodiment after the intelligent sofa is converted into a bed according to the instruction of the user, when the user sits on the sofa shown in fig. 1, when the user wants to rest, the controller 5 in the intelligent sofa receives the conversion instruction and then sends a driving instruction to the corresponding motor of the driving assembly through some columns of processing by utilizing the control program pre-installed in the mobile phone or the remote controller matched with the sofa. One motor drives the telescopic rod 6 to start locking so that the back cushion 1 gradually rotates downwards and stops after the surface of the back cushion 1 is flush with the surface of the base 2, meanwhile, the other motor drives the connecting shaft to rotate so that the auxiliary support 16 starts rotating to be perpendicular to the back cushion 1, and the other motor drives the actuating mechanism to be unfolded so that the extension cushion 4 is unfolded to be in a straight state from a state of wrapping one end of the base 2, and the extension cushion 4 is parallel to the ground and flush with the surface of the base 2. At this time, after a series of control processes are completed, the intelligent sofa is converted into a bed state.
