When switched to dining chair mode, the larger multifunctional smart sofa can accommodate multiple people for dining.

[0072] The horizontal adjustment assembly 5 includes: a horizontal drive component 51, a horizontal transmission component 52, and a horizontal guide component 53. The horizontal drive component 51 is mounted on the horizontal frame assembly 1. Specifically, the horizontal drive component 51 is a first motor. The horizontal transmission component 52 is connected to the horizontal drive component 51 and is connected to the seat cushion frame assembly 2. The horizontal transmission component 52 drives the seat cushion frame assembly 2 to move back and forth in the horizontal plane. Specifically, the horizontal transmission component 52 includes a horizontal lead screw 521 and a horizontal moving block 522. The horizontal lead screw 521 is connected to or fixedly connected to the output shaft of the horizontal drive component 51 through a coupling. The horizontal moving block 522 is threadedly engaged with the horizontal lead screw 521 and is connected to the seat cushion frame assembly 2. When the horizontal moving block 522 moves in the horizontal direction, it drives the seat cushion frame assembly 2 to move in the horizontal direction. The horizontal guide component 53 is mounted on the horizontal frame and is connected to the seat cushion frame to guide the movement of the seat cushion frame.

[0073] The horizontal guide 53 includes a horizontal guide rail and a horizontal moving member. The horizontal guide rail is connected to the horizontal frame assembly 1 and is arranged in a direction from back to front. The horizontal moving member is movably connected to the horizontal guide rail. Specifically, it can be a sliding connection, a sliding fit, a rolling connection, or a rolling fit to enable the horizontal moving member to move along the horizontal guide rail. The horizontal moving member is connected to the seat cushion frame. Specifically, the horizontal guide rail is a C-groove, and the horizontal moving member is a horizontal roller. The horizontal roller rolls in the C-groove and can slide.

[0074] The vertical adjustment assembly 6 includes: a vertical drive component 61, a vertical transmission component 62, a first connecting rod 63, a second connecting rod 64, and a vertical guide component 65. The vertical drive component 61 is mounted on the vertical frame assembly 3. Specifically, the vertical drive component 61 is a second motor. The vertical transmission component 62 is connected to the vertical drive component 61 and is connected to the backrest frame assembly 4. Specifically, the vertical transmission component 62 includes a vertical lead screw 621 and a vertical moving block 622. The vertical lead screw 621 is connected to the output shaft of the vertical drive component 61 via a coupling or fixed connection. The vertical moving block 622 is connected to the vertical lead screw 621. 1. Threaded connection; one end of the first connecting rod 63 is connected to the vertical transmission component 62, and the other end of the first connecting rod 63 is movably connected to the backrest frame assembly 4. Specifically, one end of the first connecting rod 63 is fixedly connected to the vertical moving block 622 via a strip rod 66, and the other end of the first connecting rod 63 is hinged to the backrest frame assembly 4; one end of the second connecting rod 64 is hinged to the vertical frame assembly 3, and the other end of the second connecting rod 64 is hinged to the backrest frame assembly 4; the vertical guide component 65 is installed on the vertical frame assembly 3, the vertical guide component 65 is arranged in the vertical direction, and the vertical guide component 65 is connected to the backrest frame assembly 4. The backrest frame assembly 4 is driven by the vertical driving component 61, the vertical lead screw 621, and the vertical moving block 622. The vertical lead screw 621 and the vertical moving block 622 can support the backrest frame assembly 4, thereby improving the strength of the backrest frame assembly 4.

[0075] When the sofa needs to be switched to bed mode, the horizontal drive component 51 drives the horizontal lead screw 521 to rotate, and the horizontal moving block 522 moves the seat cushion frame forward. The controller synchronously controls the horizontal drive component 51 and the vertical drive component 61 to drive simultaneously, so that the seat cushion frame assembly 2 and the backrest frame assembly 4 are linked. When the vertical drive component 61 drives the vertical lead screw 621 to rotate, the vertical moving block 622 moves downward under the action of the vertical lead screw 621. The vertical moving block 622 drives the first connecting rod 63 to move downward, and the first connecting rod 63 drives the backrest frame assembly 4. As the backrest frame assembly 4 moves downward, it drives the second link 64 to rotate. The second link 64 rotates with the point where it connects to the vertical frame assembly 3 as the center. When the second link 64 rotates, it drives the backrest frame assembly 4 to gradually rotate from a vertical state to a horizontal state. During this process, the backrest frame assembly 4 also rotates relative to the first link 63. Thus, through the coordination of various motion states and the mutual motion of multiple components, the backrest frame assembly 4 is lowered to the same height as the seat cushion frame assembly 2, and at the same time, it changes from a vertical state to a horizontal state.

[0076] The vertical guide 65 includes a vertical guide rail and a vertical moving member. The vertical guide rail is connected to the vertical frame assembly 3 and is arranged in the vertical direction. The vertical moving member is movably connected to the vertical guide rail. Specifically, it can be a sliding connection, a sliding fit, a rolling connection, or a rolling fit to enable the vertical moving member to move along the vertical guide rail. The vertical moving member is connected to the backrest frame assembly 4. Specifically, the vertical guide rail is a C-shaped groove, and the vertical moving member is a vertical moving roller. The vertical moving roller rolls and can move within the vertical guide rail. The vertical moving roller is connected to the backrest frame assembly 4 through a strip rod 66 and a first connecting rod 63.

[0077] The seat cushion frame assembly 2 is equipped with a seat cushion elastic element 7, which cushions the pressure on the seat cushion frame assembly 2. The seat cushion elastic element 7 includes multiple serpentine springs arranged parallel to each other and located in the same horizontal plane. The multiple serpentine springs are connected by connectors to achieve simultaneous cushioning. Through the connection, the multiple serpentine springs can work together to achieve a cushioning effect, avoiding the situation where only one or a few springs bear the weight and provide cushioning. This improves the overall support force and strength of the seat cushion elastic element 7 and extends its overall service life.

[0078] The seat cushion frame assembly 2 is equipped with a seat comfort adjustment device 8, which includes a support member 81. The support member 81 can abut against the seat cushion elastic member 7. The position of the support member 81 is adjustable up and down, and the support member 81 moves along an arc-shaped trajectory below the seat cushion elastic member 7. The seat comfort adjustment device 8 also includes a seat comfort drive member 82 and a seat comfort transmission member 83. The seat comfort drive member 82 is mounted on the seat cushion frame assembly 2. Specifically, the seat comfort drive member 82 is a third motor. The seat comfort transmission member 83 is driven by the seat comfort drive member 82 and is also driven by the support member 81 to drive the support member 81 to move. Specifically, the seat comfort transmission member 83 includes a seat comfort adjustment screw 831 and a seat comfort adjustment moving block 832. The seat comfort adjustment screw 831 is connected to or fixedly connected to the output shaft of the seat comfort drive member 82 through a coupling. The seat comfort adjustment moving block 832 is driven by the support member 81.

[0079] The support member 81 is movably connected to the seat cushion frame assembly 2 via a linkage assembly. The linkage assembly includes two third linkages 84 and two fourth linkages 86, as well as a middle linkage 85. The two third linkages 84 are arranged parallel to each other, and one end of the third linkage 84 is hinged to the seat feel transmission member 83. Specifically, one end of the third linkage is hinged to the seat feel adjustment moving block 832; the other end of the third linkage 84 is hinged to the middle linkage 85. The two fourth linkages 86 are arranged parallel to each other, and both ends of the middle linkage 85 are fixedly connected to the two fourth linkages 86 respectively. One end of the fourth linkage 86 is hinged to the seat cushion frame assembly 2, and the other end of the fourth linkage 86 is hinged to the support member 81.

[0080] When a heavier person sits on the sofa, the cushion elastic element 7 will sink deeper. For users with long legs, this deep sinking can affect their comfort when sitting, such as while eating or resting. The controller controls the third motor to move the seat adjustment block 832, which in turn moves the lower end of the third link 84 forward, causing the third link 84 to rotate. After the third link 84 rotates, it lifts the middle link 85, causing it to move upward along an arc. The middle link 85 then drives the fourth link 86 to swing upward. Under the action of the fourth link 86, the support element 81 moves upward along an arc, thus supporting the cushion elastic element 7 and adjusting the user's seating comfort. This adjusts the depth of the cushion sinking when the user is seated, providing a better seating experience and improving comfort. Furthermore, the support member 81 is hinged to the fourth link 86. As the support member 81 moves upward along the arc trajectory, the position of the support member 81 can be adjusted according to the user's weight and the position of the point of application. For example, it can be adjusted to be horizontal, tilted forward at a certain angle, or tilted backward at a certain angle, thereby further improving the user's comfort.

[0081] The beneficial effects of this invention are that the multifunctional smart sofa of this invention has the following advantages:

[0082] 1. The multifunctional smart sofa of the present invention can switch between three states: sofa, bed and dining chair. It has many functions, which can maximize the performance of the sofa. It also has a simple structure and occupies little space.

By linking the horizontal adjustment component 5 and the vertical adjustment component 6, the efficiency of the multifunctional smart sofa in changing from a sofa to a bed can be improved, and the compactness of the movement of the seat frame component 2 and the backrest frame component 4 can be improved, making operation simpler and more convenient.

[0085] 4. Through the setting of the first link 63, the second link 64 and multiple hinges, the backrest frame assembly 4 can be adjusted in height and can also move in an arc trajectory. It can also gradually rotate from a vertical state to a horizontal state at the same time, which makes the movement highly flexible.

[0086] 5.
