Description

Technical Field

[0001] This utility model relates to the field of sofas, and in particular to an integrated height-adjustable sofa. Background Technology

[0002] A sofa is a type of upholstered furniture. It is a multi-seat chair with soft cushions and armrests on both sides. The frame is made of wood or steel and lined with cotton or other foam materials. Overall, it is quite comfortable.

[0003] In modern furniture, most sofas are fixed at one height, failing to provide the most suitable height for users of different heights and body types. This makes it impossible to ensure that the user's spine is in a natural and comfortable position, potentially leading to back pain and other problems with prolonged use. It also increases pressure points on the body, causing excessive stress on certain parts and reducing comfort during long periods of sitting, thus diminishing the sofa's suitability for different groups. Furthermore, the lack of leg extension facilities in sofas restricts their relaxation capabilities, failing to meet the needs of people who require full leg extension and support during extended rest or television viewing. This hinders the achievement of deep, full-body relaxation and reduces the sofa's functional versatility and enjoyment. Utility Model Content

[0004] The main purpose of this utility model is to provide an integrated height-adjustable sofa that can effectively solve the problems of increased pressure points on the body, excessive pressure on certain parts of the body, reduced comfort of prolonged sitting, reduced applicability of the sofa to different groups of people, and reduced demand for full leg extension and support, making it difficult to achieve a deep relaxation effect, and reducing the sofa's functional diversity and fun.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated height-adjustable sofa, comprising a main body, a base box fixedly connected to the bottom of the main body, protective pads provided on both the left and right sides of the bottom of the base box, support columns fixedly connected to the front and rear sides of the upper sidewalls of the two protective pads, outer columns slidably connected to the outer sides of the four support columns, connecting columns fixedly connected to the tops of the four outer columns, the tops of the four connecting columns fixedly connected to the inner upper sidewall of the base box, support rods fixedly connected to the middle of the upper sidewalls of the two protective pads, lead screws threadedly connected to the interior of the four support rods, sleeves fixedly connected to the inner upper sidewall of the base box, the tops of the two lead screws rotatably connected to the interior of the sleeves, and first bevel gears rotatably connected to the tops of the two support rods, the interiors of the two first bevel gears meshing with the lead screws.

[0006] Furthermore, a first support plate is fixedly connected to the rear sidewall of the two support rods, and a fixing block is fixedly connected to both the left and right sides of the first support plate. A motor is provided on the right side of the upper sidewall of the right fixing block, and a fixture is fixedly connected to the upper sidewall of both fixing blocks.

[0007] Furthermore, a rotating rod is fixedly connected to the output end of the motor. Both ends of the rotating rod are rotatably connected to the inside of two fixtures. Second bevel gears are fixedly connected to the outer sides of both ends of the rotating rod, and the two second bevel gears mesh with the first bevel gear.

[0008] Furthermore, a first connecting rod is fixedly connected to the front interior of the main body, a leg support plate is rotatably connected to the outer side of the first connecting rod, a first connecting plate is threadedly connected to the top of the rear side wall of the leg support plate, and a second connecting plate is rotatably connected to the top of the two first connecting plates.

[0009] Furthermore, the upper sidewalls of the two second connecting plates are threaded to the front interior of the main body, and the two slots on the rear sidewall of the leg support plate are fixedly connected to the second connecting rods. The interior of the base box is fixedly connected to the second support plate, and electric push rods are provided on both the left and right sides of the interior of the second support plate.

[0010] Furthermore, connecting blocks are fixedly connected to both the left and right sides of the interior of the second support plate, and first hinge frames are fixedly connected to the rear sides of the two electric push rods. The two first hinge frames are rotatably connected to the outer sides of the two connecting blocks.

[0011] Furthermore, each of the two electric push rod telescopic ends is fixedly connected to a second hinge frame, and the front sides of the two second hinge frames are rotatably connected to the outside of the two second connecting rods.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through its protective pad, outer column, sleeve, motor, and second bevel gear, solves the problem of increased pressure points on the body, causing excessive pressure on certain parts of the body, reducing comfort during prolonged sitting, and decreasing the sofa's suitability for different users. When the support rod fixedly connected to the middle of the upper side wall of the protective pad moves up and down, it drives the support columns fixed to the front and rear sides of the upper side wall of the protective pad to slide synchronously within the outer column. The top of the support column is fixedly connected to the upper side wall inside the base box via a connecting column. Therefore, the movement of the support rod ultimately causes the base box and the main body fixed to the base box to rise or fall, effectively ensuring that the user's feet can rest flat on the ground, reducing body pressure, alleviating fatigue from prolonged sitting, reducing cleaning dead spots, and making sofa maintenance easier.

[0014] 2. By incorporating a leg rest, a second connecting plate, a connecting block, an electric push rod, a second hinge frame, and a second connecting rod, the design addresses the issue of insufficient leg extension and support, hindering deep relaxation and reducing the sofa's functionality and appeal. The first connecting plate, threaded to the top of the rear side wall of the leg rest, moves accordingly. The second connecting plate, rotatably connected to the top of the first connecting plate, is threaded to the inside of the front of the main body. This structure ensures the stability of the leg rest during unfolding and retraction. The threaded and rotatable connections constrain and guide the movement of the leg rest, effectively reducing pressure on various parts of the body and providing an ultimate relaxation experience. This keeps all parts of the body in a comfortable and stable state, enhancing overall comfort.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 - Figure 7 As shown: An integrated height-adjustable sofa includes a main body 1, with a base box 2 fixedly connected to the bottom of the main body 1. The base box 2 supports and secures the internal components of the main body 1 and the base box 2. Protective pads 3 are provided on both the left and right sides of the bottom of the base box 2, which protect the bottom of the base box 2 from the ground and reduce friction and wear.

[0028] Support columns 4 are fixedly connected to the front and rear sides of the upper sidewalls of the two protective pads 3. The outer sides of the four support columns 4 are slidably connected to the outer columns 5. The tops of the four outer columns 5 are fixedly connected to the connecting columns 6. The tops of the four connecting columns 6 are fixedly connected to the inner upper sidewall of the base box 2. The outer columns 5 are connected to the inner top wall of the base box 2 through the connecting columns 6. When being driven to lift, the inside of the outer columns 5 will slide on the outside of the support columns 4, and the four support columns 4 and the outer columns 5 will provide bottom support for the main body 1.

[0029] Support rods 7 are fixedly connected to the middle of the upper sidewalls of both protective pads 3. Lead screws 8 are threaded into the interior of the four support rods 7. When the lead screws 8 are driven, their outer sides thread with the support rods 7, causing the support rods 7 to move up and down along the lead screws 8. Sleeves 9 are fixedly connected to the upper interior sidewalls of the base box 2. The top ends of the two lead screws 8 are rotatably connected to the inside of the sleeves 9. The connection between the sleeves 9 at the top of the base box 2 and the top ends of the lead screws 8 allows the lead screws 8 to rotate within the sleeves 9. First bevel gears 10 are rotatably connected to the top ends of both support rods 7. The interiors of the two first bevel gears 10 mesh with the lead screws 8. The meshing of the interiors of the first bevel gears 10 at the top of the support rods 7 with the outer sides of the lead screws 8 causes the first bevel gears 10 to be driven, thus driving the lead screws 8 to rotate.

[0030] Two support rods 7 are fixedly connected to the rear sidewalls of a first support plate 11. Fixing blocks 12 are fixedly connected to both the left and right sides of the first support plate 11. A motor 13 is installed on the upper right sidewall of the right fixing block 12, supporting the motor 13 at the top via the fixing blocks 12. Fixers 15 are fixedly connected to the upper sidewalls of both fixing blocks 12. A rotating rod 14 is fixedly connected to the output end of the motor 13. Both ends of the rotating rod 14 are rotatably connected inside the two fixings 15. Second bevel gears 16 are fixedly connected to the outer sides of both ends of the rotating rod 14. The two second bevel gears 16 mesh with the first bevel gear 10, and the motor... The output end of 13 drives the rotating rod 14 to rotate, and the second bevel gear 16, which is fixedly connected to the outer sides of the left and right ends of the rotating rod 14, rotates synchronously. Since the second bevel gear 16 meshes with the first bevel gear 10, the rotation of the second bevel gear 16 will drive the first bevel gear 10, which meshes with it, to rotate. The first bevel gear 10 is installed at the top of the support rod 7 and meshes with the lead screw 8 inside. Therefore, when the first bevel gear 10 rotates, it will cause the lead screw 8 to rotate threadedly inside the support rod 7. The top of the lead screw 8 is rotatably connected to the inside of the sleeve 9. During the rotation of the lead screw 8, due to its threaded engagement with the support rod 7, the support rod 7 will move up and down along the lead screw 8.

[0031] A first connecting rod 18 is fixedly connected to the front interior of the main body 1, and a leg support plate 17 is rotatably connected to the outer side of the first connecting rod 18. By fixing the first connecting rod 18 to the front interior of the main body 1 and the front interior of the base box 2, the outer leg support plate 17 is supported, so that the first connecting rod 18 can be rotated easily.

[0032] The top of the rear sidewall of the leg support plate 17 is threaded with a first connecting plate 19. The top of each of the two first connecting plates 19 is rotatably connected with a second connecting plate 20. The upper sidewall of the two second connecting plates 20 is threaded to the front interior of the main body 1. During the rotation and unfolding of the leg support plate 17, the first connecting plates 19 threaded to the top of the rear sidewall of the leg support plate 17 move accordingly. The top of the second connecting plate 20 rotatably connected to the top of the first connecting plate 19 is threaded to the front interior of the main body 1, ensuring the stability of the leg support plate 17 during unfolding and retraction.

[0033] The second connecting rod 26 is fixedly connected to the two slots on the rear side wall of the leg support plate 17. The second connecting rod 26 is installed and placed through the slots on the rear side wall of the leg support plate 17. The second support plate 21 is fixedly connected to the inside of the bottom box 2. Electric push rods 23 are provided on both the left and right sides of the inside of the second support plate 21. The electric push rods 23 and connecting blocks 22 and other devices inside are supported at the bottom by the second support plate 21.

[0034] Connecting blocks 22 are fixedly connected to both the left and right sides of the interior of the second support plate 21. The rear sides of the two electric push rods 23 are fixedly connected to the first hinge frame 24. When the extension end of the electric push rod 23 drives the leg support plate 17 to extend, the overall angle of the electric push rod 23 will change. It is connected to the first hinge frame 24 on the rear side of the electric push rod 23 through the connecting block 22 to facilitate the support of the electric push rod 23 and allow the first hinge frame 24 to rotate inside the connecting block 22. Two first hinge frames 24 are rotatably connected to the outside of two connecting blocks 22. The telescopic ends of two electric push rods 23 are fixedly connected to second hinge frames 25. The front sides of the two second hinge frames 25 are rotatably connected to the outside of two second connecting rods 26. After the electric push rod 23 is activated, its telescopic end extends forward, driving the second hinge frame 25 fixedly connected to it to move forward. The front side of the second hinge frame 25 is rotatably connected to the outside of the second connecting rod 26 fixed in the hole groove on the rear side wall of the leg support plate 17. As the second hinge frame 25 moves forward, it will push the leg support plate 17 to rotate around the first connecting rod 18 as the axis, thereby driving the leg support plate 17 to extend outward.

[0035] It should be noted that this utility model is an integrated lifting sofa with height adjustment function. First, the motor 13 and electric push rod 23 are connected to an external power supply and control terminal to supply power to the device.

[0036] When the sofa height needs to be adjusted, motor 13 is turned on. The output end of motor 13 drives the rotating rod 14 to rotate, and the second bevel gear 16, which is fixedly connected to the outer sides of the left and right ends of the rotating rod 14, rotates synchronously. Since the second bevel gear 16 meshes with the first bevel gear 10, the rotation of the second bevel gear 16 will drive the first bevel gear 10, which meshes with it, to rotate. The first bevel gear 10 is installed at the top of the support rod 7 and meshes with the lead screw 8 inside. Therefore, when the first bevel gear 10 rotates, it will cause the lead screw 8 to rotate threadedly inside the support rod 7. The top end of the lead screw 8 is rotatably connected to the inside of the sleeve 9. During the rotation of the lead screw 8, due to its threaded engagement with the support rod 7, the support rod 7 will move up and down along the lead screw 8.

[0037] When the support rod 7, which is fixedly connected to the middle of the upper side wall of the protective pad 3, moves up and down, it drives the support columns 4, which are fixed on the front and rear sides of the upper side wall of the protective pad 3, to slide synchronously within the outer columns 5 on their outer sides. The top of the support column 4 is fixedly connected to the upper side wall inside the base box 2 through the connecting column 6. Therefore, the movement of the support rod 7 ultimately drives the base box 2 and the main body 1 fixed on the base box 2 to rise or fall, thereby realizing the adjustment of the sofa height.

[0038] When the user needs to use the leg support function, the electric push rod 23 is activated. The rear side of the electric push rod 23 is rotatably connected to the outside of the connecting block 22 via the first hinge frame 24. The connecting block 22 is fixed inside the left and right sides of the second support plate 21, which is fixed inside the base box 2. After the electric push rod 23 is activated, its telescopic end extends forward, driving the second hinge frame 25, which is fixedly connected to it, to move forward. The front side of the second hinge frame 25 is rotatably connected to the outside of the second connecting rod 26, which is fixed in the slot on the rear side wall of the leg support plate 17. As the second hinge frame 25 moves forward, it pushes the leg support plate 17 to rotate about the first connecting rod 18 as an axis. The first connecting rod 18 is fixed inside the front side of the main body 1, and the leg support plate 17 is rotatably connected to its outside.

[0039] During the rotation and unfolding of the leg support plate 17, the first connecting plate 19, which is threaded to the top of the rear side wall of the leg support plate 17, moves accordingly. The second connecting plate 20, which is rotatably connected to the top of the first connecting plate 19, is threaded to the inside of the front side of the main body 1. This structure ensures the stability of the leg support plate 17 during unfolding and retraction. Through the threaded connection and rotational connection, the movement trajectory of the leg support plate 17 is constrained and guided.

[0040] When the leg support plate 17 needs to be retracted, the electric push rod 23 retracts, driving the second hinge frame 25 to move backward, thereby pulling the leg support plate 17 to rotate in the opposite direction about the first connecting rod 18, returning it to its initial retracted state. Throughout the process, all components work together. The electric push rod 23 provides power, the hinge frame and connecting rod realize the transmission of force and the change of movement direction, and the threaded connecting plate ensures the stability and controllability of the movement of the leg support plate 17.
