Description

Technical Field

[0001] This utility model relates to the field of home furniture technology, and in particular to a sliding and height-adjustable sofa frame. Background Technology

[0002] With the advancement of the times and the upgrading of consumers' functional requirements for sofas, consumers expect sofas to provide more than just seating. They also have higher requirements for seating comfort, practicality, functionality, pressure relief, comfort, and technological feel. Traditional scissor-type lifting frames rely on manual operation, which is time-consuming and requires a lot of external force, especially for elderly users or heavier users. Although electric push rod lifting can achieve automation, it has a complex structure and high manufacturing cost. Moreover, if there is a sudden power failure or operational error during the lifting process, the sofa is prone to fall rapidly due to inertia, causing damage to the bottom. Therefore, those skilled in the art provide a sliding and lifting sofa frame to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a sliding and height-adjustable sofa frame.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A sliding and height-adjustable sofa frame includes a fixed frame. Sliding grooves are formed on both sides of the top surface of the fixed frame. Sliding blocks are slidably connected to both sides of the sliding grooves. A slot is formed on the top surface of each sliding block, and a rod is inserted into the slot. An X-shaped rod is rotatably connected to the surface of the rod. A connecting rod is provided on one side of the sliding block. A driving assembly is provided on one side of the top surface of the fixed frame. Damping telescopic rods are fixedly installed on both sides of the top surface of the connecting rod. A buffer spring is sleeved on the outer surface of the damping telescopic rod. A flexible block is fixedly installed on the top of the buffer spring. A guide rod is fixedly connected to one side of the sliding block. An overlapping plate is fixedly installed on one side of the guide rod. Support blocks are fixedly connected to both sides of the bottom of the overlapping plate. Guide blocks are fixedly connected to both sides of the outer surface of the fixed frame. The inner wall of the guide block is slidably connected to the outer surface of the guide rod.

[0005] As a further embodiment of this utility model, the driving component includes a mounting block fixedly connected to one side of the outer surface of the fixed frame. A servo motor is fixedly mounted on one side of the mounting block, and a bidirectional screw is fixedly mounted on the output end of the servo motor. Both sides of the surface of the bidirectional screw are threaded through the middle of the surface of the connecting rod.

[0006] As a further embodiment of this utility model, a rotating rod is rotatably connected to the middle of the surface of the X-shaped rod, and a slider is fixedly installed at one end of the X-shaped rod.

[0007] As a further improvement of this utility model, through holes are provided on both sides of the top of the fixed frame, and a lead screw passes through the internal thread of the through hole.

[0008] As a further embodiment of this utility model, a circular block is fixedly installed on the top of the lead screw, and an abutment block is rotatably connected to the bottom of the lead screw.

[0009] As a further embodiment of this utility model, a circular piece is fixedly connected to the bottom of the buffer spring, and the bottom of the circular piece is fixedly connected to the surface of the connecting rod.

[0010] As a further embodiment of this utility model, an anti-detachment block is fixedly installed at one end of the bidirectional screw, and the diameter of the anti-detachment block is larger than the diameter of the bidirectional screw.

[0011] As a further embodiment of this invention, a waterproof membrane for increasing water resistance is attached to the outer surface of the fixing frame, and a resistance pad is attached to the bottom of the fixing frame.

[0012] The beneficial effects of this utility model are as follows: 1. By setting up guide rods, overlapping plates, and guide blocks, when people adjust the height of the sofa, its sliding block moves towards the center along the sliding groove. Then, the sliding block pushes the guide rod to one side, causing the guide rod to drive the overlapping plate to expand to both sides of the fixed frame. This makes it easier to adjust the sofa's deformation and accommodate different sitting postures, thereby expanding the usable area of ​​the sofa.

[0013] 2. By setting up the drive assembly, X-shaped rod, connecting rod, and sliding block, when the user needs to raise the sofa, the user can turn on the servo motor power, causing the servo motor to drive the bidirectional screw to rotate. Then, the bidirectional screw drives the connecting rod and sliding block to move towards the center along the sliding groove. Subsequently, the sliding block drives the X-shaped rod to merge, causing the X-shaped rod to lift the sofa upwards, thus facilitating the lifting of the sofa by the user.

[0014] 3. By using a damping telescopic rod, connecting rod, and buffer spring, when the sofa needs to be lowered slowly, the X-shaped rod moves the sofa downwards, causing the bottom of the sofa to contact the top of the flexible block and buffer spring. The buffer spring then contracts, thus cushioning the sofa during its descent and reducing the risk of damage to the bottom of the sofa from a rapid fall. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0018] Reference Figures 1-4 A sliding and height-adjustable sofa frame includes a fixed frame 1. Sliding grooves are provided on both sides of the top surface of the fixed frame 1. Sliding blocks 2 are slidably connected to both sides of the sliding grooves. A slot is provided on the top surface of the sliding block 2, and a rod 3 is inserted into the slot. An X-shaped rod 4 is rotatably connected to the surface of the rod 3. A connecting rod 6 is provided on one side of the sliding block 2. A drive assembly 5 is provided on one side of the top surface of the fixed frame 1. The drive assembly 5 includes a mounting block 51 fixedly connected to one side of the outer surface of the fixed frame 1. A servo motor 52 is fixedly mounted on one side of the mounting block 51. A bidirectional screw 53 is fixedly mounted on the output end of the servo motor 52. Both sides of the surface of the bidirectional screw 53 are threaded through the middle of the surface of the connecting rod 6. An anti-detachment block is fixedly mounted on one end of the bidirectional screw 53, and the diameter of the anti-detachment block is larger than the diameter of the bidirectional screw 53.

[0019] When the sofa needs to be raised, the operator can turn on the servo motor 52, causing the bidirectional screw 53 to rotate. The bidirectional screw 53 then drives the connecting rod 6 and the sliding block 2 to move towards the center along the sliding groove, causing the insert rod 3 to drive the X-shaped rod 4 to merge towards the center. The X-shaped rod 4 then lifts the sofa upwards. When the sofa needs to be lowered, the operator can turn on the servo motor 52, causing the bidirectional screw 53 to reverse. The bidirectional screw 53 then drives the connecting rod 6 to slide to both sides along the sliding groove, causing the X-shaped rod 4 to spread out to both sides. This then moves the sofa downwards, and upon contact with the top surface of the flexible block 9, the buffer spring 8 contracts under pressure, subsequently driving the damping telescopic rod 7 to slow down the movement, thus facilitating the operator's cushioning operation of the sofa.

[0020] In this utility model, damping telescopic rods 7 are fixedly installed on both sides of the top surface of the connecting rod 6. A buffer spring 8 is sleeved on the outer surface of the damping telescopic rod 7. A flexible block 9 is fixedly installed on the top of the buffer spring 8. A circular piece is fixedly connected to the bottom of the buffer spring 8. The bottom of the circular piece is fixedly connected to the surface of the connecting rod 6. A waterproof membrane for increasing waterproofness is attached to the outer surface of the fixing frame 1. A resistance pad is attached to the bottom of the fixing frame 1.

[0021] With the damping telescopic rod 7, connecting rod 6 and buffer spring 8 in place, when the sofa needs to be lowered slowly by personnel, the X-shaped rod 4 moves the sofa downwards, so that the bottom of the sofa comes into contact with the top of the flexible block 9 and the buffer spring 8. Then the buffer spring 8 contracts, thus buffering the sofa during the descent and reducing the possibility of the sofa falling to the ground quickly and causing damage to the bottom of the sofa.

[0022] Reference Figures 1-4 A guide rod 15 is fixedly connected to one side of the sliding block 2, and an overlapping plate 16 is fixedly installed on one side of the guide rod 15. Support blocks 17 are fixedly connected to both sides of the bottom of the overlapping plate 16. Guide blocks 18 are fixedly connected to both sides of the outer surface of the fixed frame 1. The inner wall of the guide block 18 is slidably connected to the outer surface of the guide rod 15. With the guide rod 15, the overlapping plate 16 and the guide block 18, when the sofa is adjusted in height, the sliding block 2 moves towards the center along the sliding groove. Then the sliding block 2 pushes the guide rod 15 to one side, so that the guide rod 15 drives the overlapping plate 16 to expand to both sides of the fixed frame 1, making it easier to adjust the sofa deformation and meet the sitting posture of different people, thereby expanding the usable area of ​​the sofa.

[0023] In particular, a rotating rod 10 is rotatably connected to the middle of the surface of the X-shaped rod 4, and a slider 11 is fixedly installed at one end of the X-shaped rod 4.

[0024] The rotating rod 10 and the slider 11 are designed to assist the X-shaped rod 4 in raising and lowering.

[0025] In particular, through holes are provided on both sides of the top of the fixed frame 1, and a screw rod 12 is threaded through the inside of the through holes. A circular block 13 is fixedly installed on the top of the screw rod 12, and an abutment block 14 is rotatably connected to the bottom of the screw rod 12. With the arrangement of the circular block 13, the lead screw 12 and the abutment block 14, when personnel need to lift the fixed frame 1, they can turn the circular block 13 to drive the lead screw 12 to lift the fixed frame 1 upward, thus facilitating the lifting of the fixed frame 1.

[0026] Working principle: When a person needs to raise the sofa, they can turn on the servo motor 52, causing the bidirectional screw 53 to rotate. The bidirectional screw 53 then drives the connecting rod 6 and the sliding block 2 to move towards the center along the sliding groove, causing the insert rod 3 to drive the X-shaped rod 4 to merge towards the center. The X-shaped rod 4 then lifts the sofa. Next, when the person adjusts the sofa's height, the sliding block 2 moves towards the center along the sliding groove. The sliding block 2 then pushes the guide rod 15 to one side, causing the guide rod 15 to drive the overlapping plate 16 to expand towards both sides of the fixed frame 1, thus... It allows for easy adjustment of the sofa's deformation to accommodate different sitting postures, thereby expanding the sofa's usable area. When the user needs to lower the sofa, they can connect the servo motor 52 to reverse the bidirectional screw 53. The bidirectional screw 53 then drives the connecting rod 6 to slide along the sliding groove to both sides, causing the X-shaped rod 4 to spread out to both sides. This then moves the sofa downwards, and when it contacts the top surface of the flexible block 9, the buffer spring 8 is compressed and then drives the damping telescopic rod 7 to slow down, thus facilitating the user's cushioning operation of the sofa.

[0027] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described in detail here.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
