[0002] Sofas have become an essential piece of furniture in many homes, providing a comfortable resting environment for users during their leisure time. With the advancement of technology, smart sofas have become an indispensable and important choice when people choose furniture to meet their needs.

[0003] For example, Chinese patent CN216534596U discloses a smart sofa that is easy to adjust to adapt to different postures; it includes a sofa body; a foot support component is provided at the bottom of the front end of the sofa body, and a back adjustment component is rotatably provided at the rear end; and a storage component is rotatably provided on the outer wall of one side; the foot support component includes a foot load-bearing plate with several rectangular insertion slots opened horizontally at the top and a leg support plate with a limit rod rotatably connected at the bottom; and the limit rod is inserted into the rectangular insertion slot.

[0004] The aforementioned smart sofa has the advantage of using storage nets to store items; however, it still has some drawbacks, such as the lack of foreign object detection and anti-pinch functions. Pets, children, items, or hands and feet can easily be placed at the bottom of the smart sofa. During the rotation and adjustment of the sofa's leg support plate, it cannot detect the condition of the bottom of the smart sofa in time. When the sofa's leg support plate retracts, it can easily pinch pets, children, items, or hands and feet lying at the bottom of the smart sofa, reducing the safety performance of the smart sofa. Therefore, its control system needs to be improved. Summary of the Invention

One rotating component 4 is connected to a sofa backrest frame 5, and the other rotating component 4 is connected to a sofa leg frame 6. The rotating component 4 includes a rotating rod 41, two L-shaped mounting blocks 42, and two connecting plates 43. Both ends of the rotating rod 41 are rotatably connected to the two bearing seats 19 via bearings. Two L-mount blocks 42 and two connecting plates 43 are symmetrically fixed on the circumferential surface of the rotating rod 41. The L-mount blocks 42 are fixedly connected to the sofa back frame 5 and the sofa leg frame 6 respectively by screws. The connecting plates 43 are connected to the connecting rods 7. When the two ends of the rotating rod 41 rotate on the two bearing seats 19 through bearings, it facilitates the simultaneous rotation of the two L-mount blocks 42 and the two connecting plates 43, which in turn facilitates the rotation of the sofa back frame 5, the sofa leg frame 6, and the two connecting rods 7, achieving a linkage effect for sofa adjustment and precisely controlling the adjustment angle of the sofa. Two connecting rods 7 connect the components 4. A push rod rotating assembly 8 is fixed between the sofa back frame 5 and the base plate 1. The push rod rotating assembly 8 includes a first hinge block 81, an electric push rod 82, and a connecting rotating frame 83. The first hinge block 81 is fixed to the base plate 1, and both ends of the connecting rotating frame 83 are fixed to the sofa back frame 5. One end of the electric push rod 82 is hinged to the first hinge block 81, and the other end is fitted onto the connecting rotating frame 83. The electric push rod 82 hinged to the first hinge block 81 can be connected to the sofa back frame 5 through the connecting rotating frame 83, facilitating the control of the sofa back. The backrest frame 5 is used at various angles. The connecting rod 7 includes a threaded telescopic tube 71 and two connecting blocks 72. The two connecting blocks 72 are fixed to both ends of the threaded telescopic tube 71 and are respectively fitted onto two connecting plates 43. The two ends of the threaded telescopic tube 71 are fixedly connected to the two connecting blocks 72. The two connecting blocks 72 can be connected to the two connecting plates 43 to facilitate the transmission of power. When the sofa backrest frame 5 rotates, it can drive the sofa leg frame 6 to adjust. The threaded telescopic tube 71 can flexibly adjust the length of the connection according to the distance between the two connecting plates 43. An infrared sensor 9 is installed on one side of the sofa leg frame 6.

The upper end of the swing rod 122 is fixedly connected to the second bevel gear 11, and the lower end is fixedly connected to the mounting plate 123. The swing rod 122 can rotate on the rotating plate 121 through the bearing. When the second bevel gear 11 fixed at the upper end of the swing rod 122 meshes with the first bevel gear 10, it can drive the mounting plate 123 to rotate, which can swing the infrared sensor 9, adjust the detection range, and increase the monitoring area.

[0031] In use, the support frame 2 can fix the main frame 3 of the sofa. The bearing seats 19 fixed on both sides of the main frame 3 are rotatably connected to two rotating components 4, which rotatably connect the backrest frame 5 and the leg frame 6 of the sofa. When the push rod rotating component 8 is extended and retracted, it can precisely control the rotation range of the backrest frame 5. The two connecting rods 7 connected between the rotating components 4 can drive the leg frame 6 to rotate simultaneously, thereby controlling the adjustment angle of the sofa and improving comfort. The first bevel gear 10 fixed on one of the rotating components 4 can... The second bevel gear 11 fixed at the upper end of the swing rod 12 meshes with the first bevel gear 10, which can drive the infrared sensor 9 installed on the swing rod 12 to swing, thereby adjusting the working angle of the infrared sensor 9 and increasing the sensing range of the area below the sofa leg frame 6. This allows for accurate detection of pets, children, items, or hands and feet at the bottom of the sofa. If a pet, child, item, or hand or foot is detected, the push rod rotation component 8 of the smart sofa control system will stop immediately, preventing injury to pets, children, items, or hands and feet and improving the safety performance of the smart sofa.

[0032] refer to Figures 1-5 Multiple reinforcing rods 13 are fixed on the support frame 2, and multiple triangular reinforcing ribs 14 are fixed between the main frame 3 of the sofa and the support frame 2. The multiple reinforcing rods 13 fixed on the support frame 2 can enhance the structural strength, and the multiple triangular reinforcing ribs 14 can improve the firmness between the main frame 3 of the sofa and the support frame 2, thereby improving the overall stability of the sofa.

[0033] refer to Figures 1-5A second hinge block 15 is fixed to the lower surface of the mounting plate 123, and one side of the infrared sensor 9 is mounted on the second hinge block 15. The second hinge block 15 allows for flexible adjustment of the vertical rotation angle of the infrared sensor 9, improving ease of use.

[0034] refer to Figures 1-5 A PLC controller 16 is fixed on the base plate 1. The PLC controller 16 is electrically connected to the push rod rotating assembly 8 and the infrared sensor 9 through wires. The PLC controller 16 can conveniently control the operation of the push rod rotating assembly 8 and the infrared sensor 9, thereby improving the accuracy of sofa control. The method of the infrared sensor 9 to detect items and pets under the sofa can be applied in various occasions, such as chairs, folding beds, and telescopic tables, to improve the safety performance of use.

[0035] refer to Figures 1-5 The PLC controller 16 is equipped with a voice collection module, a voice processing module, and a voice command control module. The voice collection module collects the voice control commands issued by the user and sends them to the voice processing module. The voice processing module extracts and processes the sofa control keywords from the collected voice control commands and sends them to the voice command control module. The voice command control module performs relevant actions based on the sofa control keywords. The cooperation of the voice collection module, voice processing module, and voice command control module facilitates the operation of the intelligent sofa control system via voice control.

[0036] refer to Figures 1-5A padded side panel 17 is fixed to the side surface of the support frame 2. Padded pads 18 are fixed to the main frame 3, backrest frame 5, and leg frame 6 of the sofa. The padded side panels 17 and padded pads 18 improve the comfort of the smart sofa. A rotating seat 22 is fixed to the lower surface of the leg frame 6. A servo motor 20 is fixed to the rotating seat 22. A support plate 21 is provided inside the rotating seat 22 and fixed to the motor shaft of the servo motor 20. The padded side panels 17 and padded pads 18 improve the comfort of the smart sofa control system. A rotating seat 22 is fixed to the bottom of the leg frame 6. The seat 22, in conjunction with the servo motor 20, drives the support plate 21 to rotate. During the rotation, the support plate 21 can remove simple items located under the sofa leg frame 6. If the simple items are pushed out, the infrared sensor 9 sends a signal to the servo motor 20 to make the support plate 21 rotate back. Then, the push rod rotation component 8 of the sofa control system continues to operate, causing the sofa to retract and return to its normal state. If there are still obstacles under the sofa leg frame 6 after the support plate 21 rotates, the support plate 21 can provide support, thus assisting the person sitting on the sofa to put their feet down. Without the support plate 21... If the sofa legs are still some distance off the ground, it's difficult for someone sitting on the sofa to get off. Therefore, a support plate 21 is added to provide support, allowing people to easily get off the sofa even before it returns to its normal position and remove any foreign objects underneath. Specifically, when the infrared sensor 9 detects an object, the servo motor 20 controls the rotation angle of the support plate 21, stopping it on the ground and preventing the chair from retracting. This adds a secondary safety measure on top of the already stopped push rod rotation assembly 8, because under normal circumstances, if the infrared sensor... When a foreign object is detected under the sofa, the push rod rotating assembly 8 will stop moving. At this time, the person sitting on the sofa may not realize that there is a problem under the sofa and may try to use their own force to continue to retract the sofa. At this time, they may overcome the force of the push rod rotating assembly 8 and cause the sofa legs to continue to press down. However, because of the presence of the support plate 21, it can provide physical resistance by supporting on the ground, so that the person sitting on the sofa cannot use their leg strength to continue to compress the sofa legs, which can effectively avoid pinching injury. This prevents the person sitting on it from causing injury when they try to forcefully retract the sofa leg frame 6.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
