Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] Example: like Figures 1-8 As shown, the functional sofa provided in this embodiment includes a base 1, a linkage mechanism 10, a leg assembly 2, a backrest assembly 3, a soft-padded assembly 4, a vibration assembly 5, and a heating assembly 6; as Figures 5-8 As shown, the linkage mechanism 10 is hinged to the base 1. The leg assembly 2 and the backrest assembly 3 are respectively hinged to both sides of the linkage mechanism 10, and the leg assembly 2 and the backrest assembly 3 can rotate relative to the linkage mechanism 10 to adjust their tilt angles relative to the base 1. The linkage mechanism 10 is used to enable the leg assembly 2 and the backrest assembly 3 to swing on the base 1. Figures 1-4 As shown, the soft padding component 4 covers the leg assembly 2 and the backrest assembly 3, and the vibration component 5 and the heating component 6 are both installed inside the soft padding component 4.

[0023] The functional sofa provided in this embodiment hinges the leg assembly 2 and the backrest assembly 3 to both sides of the linkage mechanism 10, allowing the leg assembly 2 and the backrest assembly 3 to rotate relative to the linkage mechanism 10. This enables the leg assembly 2 to be tilted relative to the base 1 to support the user's legs in different postures, and the backrest assembly 3 to be tilted relative to the base 1 to support the user's back in different postures. This effectively ensures the adaptability of the functional sofa to the user's sitting, lying, and zero-gravity postures.

[0024] Specifically, such as Figure 1 , Figure 3 and Figure 6 As shown, when the leg assembly 2 is rotated relative to the base 1 until it is perpendicular to the base 1, and when the backrest assembly 3 is rotated relative to the base 1 until it is perpendicular to the base 1, the sofa is in a seated position, which can adapt to the user's sitting posture. Figure 2 and Figure 7 As shown, when the leg assembly 2 is rotated relative to the base 1 until it is approximately parallel to the base 1, and when the backrest assembly 3 is rotated relative to the base 1 until it is approximately parallel to the base 1, the sofa is in a reclining position, which can accommodate the user's reclining posture. Figure 6 As shown, when the leg assembly 2 and backrest assembly 3 are rotated relative to the base 1 to an angle of approximately 127° between them, the sofa is in a zero-gravity state, adaptable to the user's zero-gravity posture. It should be noted that the zero-gravity posture originates from the aerospace field, referring to the state in which an astronaut's body is tilted at approximately 127° in a spacecraft, with the spine naturally extended and pressure evenly distributed.

[0025] The functional sofa provided by this utility model can not only adapt to different user postures, but also realize the swinging of the leg assembly 2 and backrest assembly 3 on the base 1 through the linkage mechanism 10. For example, the user can drive the leg assembly 2 and backrest assembly 3 to swing through their own shaking. Since the leg assembly 2 and backrest assembly 3 are respectively installed on both sides of the linkage mechanism 10, and as... Figure 8 As shown, the linkage mechanism 10 is hinged to the base 1 via a pin or other hinge. Therefore, the leg assembly 2 and the backrest assembly 3 will drive the linkage mechanism 10 to rotate, thereby enabling the leg assembly 2 and the backrest assembly 3 to swing on the base 1 and achieve the rocking chair function.

[0026] It should be noted that using the linkage mechanism 10 to realize the rocking function of the seat is existing technology. For example, the linkage mechanism 10 can be a spring linkage mechanism 10. In this case, the balance control of the rocking motion can be realized through the linkage between the spring return and the linkage. Since the linkage mechanism 10 used to realize the rocking function of the functional sofa is existing technology, its specific structure and specific operating principle will not be described in detail here.

[0027] Furthermore, the functional sofa provided in this embodiment can also generate vibration through the vibration component 5 to achieve a vibration massage effect, and generate heat through the heating component 6 to achieve a heat therapy effect. Therefore, the functional sofa provided in this embodiment not only has a rotatable backrest component 3 and a rotatable leg component 2 to adapt to the user's sitting, lying, and zero-gravity postures, but also combines rocking chair, vibration massage, and heat therapy functions, effectively improving the functionality and comfort of the sofa.

[0028] Compared with the prior art, the functional sofa provided in this embodiment can not only rotate the leg assembly 2 and the backrest assembly 3 to adapt to different user postures, but also realize the rocking function through the linkage mechanism 10, the vibration massage function through the vibration assembly 5, and the heating function through the heating assembly 6, effectively improving the comfort of use.

[0029] It should also be noted that the functional sofa provided in this embodiment may also include a seat frame, the base 1 is a partial structure of the seat frame, the soft padding component 4 covers the outside of the seat frame, the seat frame is used as the main support structure of the functional sofa, and the soft padding component 4 is used to improve the user's comfort.

[0030] In this embodiment, the vibration component 5 includes a vibration switch, and the heating component 6 includes a heating switch. The vibration switch is used to control the start and stop of the vibration component 5, and the heating switch is used to control the start and stop of the heating component 6. Both the vibration switch and the heating switch are installed on the outside of the soft package component 4.

[0031] The vibration switch and heating switch allow users to select between vibration and heat therapy modes according to their needs. To further enhance the ease of operation of the vibration and heating switches, such as... Figure 1 As shown, a control panel 7 can be installed on the outside of the upholstered component 4 near the armrest of the sofa. Both the vibration switch and the heating switch are installed on the control panel 7.

[0032] Both the vibration switch and the heating switch can be physical switches such as knobs or buttons, or they can be touch buttons.

[0033] like Figure 9 and Figure 10 As shown, the soft-pack assembly 4 includes a backrest area 40, and a movable assembly 8 is installed inside the soft-pack assembly 4 in the backrest area 40. The movable assembly 8 includes an output end that can move along the height direction of the backrest area 40, and a massage head assembly 80 is installed at the output end of the movable assembly 8.

[0034] The massage head assembly 80 is prior art. For example, the massage head assembly 80 may include a motor and a massage block. The motor drives the massage block to rotate, thereby massaging the user's back. The moving assembly 8 is used to move the massage head assembly 80 along the height direction of the backrest area 40 inside the soft-padded assembly 4 of the backrest area 40, thereby achieving massage of different parts of the user's back.

[0035] like Figure 2 As shown, the upholstered assembly 4 may further include a seat area 45 and a leg area 46. The seat area 45 is located below the backrest area 40 and lies flat, while the leg area 46 is located below the seat area 45. The leg assembly 2 is installed inside the upholstered assembly 4 in the leg area 46, and the backrest assembly 3 is installed inside the upholstered assembly 4 in the backrest area 40. Figure 1 and Figure 9 As shown, vibration components 5 can be installed inside the soft-padded components 4 of the backrest area 40, seat area 45 and leg area 46, while heating components 6 are installed inside the soft-padded components 4 of the backrest area 40.

[0036] like Figure 11 and Figure 12 As shown, the movable component 8 includes a support frame 81 and a core housing 82. The support frame 81 is fixed inside the soft-pack component 4 of the backrest area 40. The core housing 82 is slidably connected to the support frame 81 along the height direction of the backrest area 40. The massage head component 80 is mounted on the core housing 82.

[0037] The support frame 81 is used to support the core housing 82, and the core housing 82 is used to support the massage head assembly 80 and drive the massage head assembly 80 to slide on the support frame 81.

[0038] The motor of the massage head assembly 80 can be installed inside the core housing 82, while the massage blocks are installed outside the core housing 82.

[0039] To enable the movement housing 82 to slide on the support frame 81, the movement housing 82 and the support frame 81 can be connected by a lead screw and a lead screw nut. At this time, the nut can be moved on the lead screw by driving the lead screw to rotate by the motor, thereby enabling the movement housing 82 to slide on the support frame 81.

[0040] Or, such as Figure 11 and Figure 12 As shown, the support frame 81 is provided with a rack 810 extending along the height direction of the backrest area 40. The internal housing 82 is equipped with a walking motor and a walking gear. The side of the internal housing 82 facing the rack 810 is provided with an opening. The teeth on the walking gear pass through the opening and mesh with the rack 810. The output end of the walking motor is connected to the walking gear to drive the walking gear to rotate.

[0041] After the walking motor drives the walking gear to rotate, the walking gear can move on the rack 810, and at the same time drive the core housing 82 to slide on the support frame 81, so as to realize the movement of the massage head assembly 80 in the height direction of the backrest area 40.

[0042] like Figure 11 As shown, the soft-padded component 4 of the backrest area 40 is also equipped with a first limit switch 83 and a second limit switch 84 that are spaced apart. The output end of the moving component 8 moves along the height direction of the backrest area 40 in the interval between the first limit switch 83 and the second limit switch 84.

[0043] The first limit switch 83 and the second limit switch 84 can both be installed on the support frame 81. The first limit switch 83 and the second limit switch 84 can cooperate with each other to limit the movement of the movement of the movement housing 82 on the support frame 81 and prevent the movement housing 82 from detaching from the support frame 81.

[0044] Furthermore, such as Figure 14 As shown, the functional sofa provided in this embodiment may include a control system 70. The first limit switch 83, the second limit switch 84, and the walking motor are all connected to the control system 70. When the core housing 82 moves to the first limit switch 83, the first limit switch 83 is closed. At this time, the control system 70 can receive the closing information of the first limit switch 83 and control the walking motor to close. Correspondingly, when the core housing 82 moves to the second limit switch 84, the second limit switch 84 is closed. At this time, the control system 70 can receive the closing information of the second limit switch 84 and control the walking motor to close.

[0045] The massage head assembly 80 includes a massage switch, which is used to control the start and stop of the massage head assembly 80 and adjust the massage intensity of the massage head assembly 80. The massage switch is located on the outside of the soft pack assembly 4.

[0046] like Figure 1 As shown, when a control panel 7 is installed on the outer side of the upholstered component 4 near the armrest of the sofa, the massage switch can also be installed on the control panel 7.

[0047] like Figure 1 As shown, in this embodiment, the soft pack component 4 may include a neck support and a lumbar support, and both the neck support and the lumbar support are provided with an inflatable airbag component 44.

[0048] The airbag assembly 44 of the neck support is used to support the user's neck after inflation, and the airbag assembly 44 of the lumbar support is used to support the user's waist after inflation.

[0049] like Figures 3-4 , Figures 13-15As shown, the soft-pack component 4 also includes an armrest area 41, on one side of which is provided a computer stand 42 and / or a mobile phone stand 43.

[0050] like Figure 1 As shown, the armrest area 41 can be two, such as Figure 13 and Figure 14 As shown, one of the two armrest areas 41 is equipped with a computer stand 42, such as Figure 14 As shown, another handrail is equipped with a mobile phone holder 43.

[0051] To further enhance the ease of use of this functional sofa, both the computer stand 42 and the mobile phone stand 43 can be detachably connected to one side of the armrest area 41 of the upholstered component 4. The detachable connection method can be screw connection or clip connection.

[0052] The airbag assembly 44 may include an airbag and an air pump 9 for inflating the airbag, such as... Figure 15 As shown, the air pump 9 can be installed inside the soft-pack component 4 of the armrest area 41 where the mobile phone holder 43 is located.

[0053] Furthermore, such as Figure 15 As shown, the airbag assembly 44 also includes a solenoid valve 90, which is used to connect to the air pump 9 to maintain pressure.

[0054] like Figures 5-7 As shown, the leg assembly 2 includes a leg support mechanism 20 and a leg drive member 21, and the backrest assembly 3 includes a backrest support mechanism 30 and a backrest drive member 31. The leg support mechanism 20 and the backrest support mechanism 30 are respectively hinged to both sides of the linkage mechanism 10. The output end of the leg drive member 21 is connected to the leg support mechanism 20, and the leg drive member 21 is used to drive the leg support mechanism 20 to rotate relative to the linkage mechanism 10. The output end of the backrest drive member 31 is connected to the backrest support mechanism 30, and the backrest drive member 31 is used to drive the backrest support mechanism 30 to rotate relative to the linkage mechanism 10.

[0055] Both the leg support mechanism 20 and the backrest support mechanism 30 can adopt a linkage structure, while both the leg drive component 21 and the backrest drive component 31 can adopt a telescopic actuator such as a cylinder or hydraulic cylinder. Since the leg support mechanism 20, the backrest support mechanism 30, the leg drive component 21 and the backrest drive component 31 are all existing technologies, their specific structures and usage processes will not be described in detail here.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
