Description

Technical Field

[0001] The present application relates to the field of furniture accessories, and in particular to a bracket with an extendable deformation structure. Background Art

[0002] A sofa is a cushioned, multi-seat chair with a spring or thick foam backrest and armrests on both sides. It is a type of soft furniture.

[0003] Sofas are indispensable furniture in home decoration. During sofa manufacturing, the sofa bracket is usually produced first and then the sofa is installed on the sofa bracket. The sofa bracket in the prior art is generally only suitable for raising and adjusting the seat cushion, and the bottom of the sofa is generally very close to the ground, which makes it inconvenient for users to clean the ground under the sofa.

[0004] Therefore, the applicant proposed a conjecture that by installing a liftable cleaning component on the bottom of the sofa, the height of the bottom of the sofa can be raised while the ground under the sofa can be automatically cleaned, thereby saving cleaning time. Based on this conjecture, the applicant proposed a bracket with an extendable deformation structure. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] The purpose of this application is to solve the problem that the sofa brackets in the prior art are generally only suitable for raising and adjusting the seat cushions, and the distance between the bottom of the general sofa and the ground is very close, which makes it inconvenient for users to clean the ground under the sofa. Compared with the prior art, a bracket with an extendable deformation structure is provided. Compared with the prior art, the bottom of the sofa body can be raised by a lifting component, so that it is away from the ground, which is convenient for subsequent users to clean the dust under the sofa body. The height of the sofa body cushion can also be adjusted, which is more convenient to use. The lifting component will drive the cleaning component while lifting the sofa, so that the cleaning component moves from the back to the front, thereby automatically cleaning the dust under the sofa body through the brush layer, so that the cleaned dust is accumulated in the front part of the sofa body, thereby saving the user's cleaning time. When the cleaning component encounters a heavy object that cannot be cleaned during cleaning, the deformable layer on the cleaning component will be deformed by the force, so the color-developing layer will also be deformed. The deformed area of ​​the color-developing layer will change color, thereby serving as a reminder to the user. The deformable layer can be retracted, so that it is convenient for the user to observe the ground, thereby improving the cleaning effect.

[0007] 2. Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] A bracket with an extending and deforming structure includes a sofa body, a lifting component, a cleaning component and a color-developing layer. The lifting components are located at the four corners of the bottom of the sofa body and are connected to the sofa body for raising the height of the bottom of the sofa body from the ground. The cleaning components are located at the bottom of the sofa body and are distributed along the length of the sofa body. The cleaning components are slidably connected to the sofa body for cleaning the ground. The color-developing layer is installed in the bottom area of ​​the cleaning component for changing the color of the area. The lifting component, the cleaning component and the color-developing layer are arranged in a coordinated manner. When the lifting component lifts the sofa body, the lifting component drives the cleaning component to move to clean dust. When heavy objects are encountered during cleaning, the color-developing layer will be deformed, thereby changing the color of the area.

[0010] Furthermore, the lifting assembly includes a lifting leg, a lifting cylinder and a driving mechanism. The top of the lifting leg is threadedly connected to the lifting cylinder, the top of the lifting cylinder is rotatably connected to the sofa body, and the driving mechanism is installed inside the sofa body to drive the lifting cylinder to rotate.

[0011] Furthermore, a limiting groove is vertically provided on the outer side of the lifting leg, and a limiting block matching the limiting groove is provided on the sofa body.

[0012] Furthermore, the driving mechanism includes a driving wheel and a chain. The chains are arranged in two groups, and the two groups of chains are respectively sleeved on the outside of the lifting cylinder along the length direction of the sofa body. A gear engaged with the chain is fixed on the outside of the lifting cylinder. A driving wheel is installed between the two groups of chains. Both groups of chains are engaged with the driving wheel. One end of the driving wheel is transmission-connected to the motor, and the end of the driving wheel away from the motor is connected to the cleaning component.

[0013] Furthermore, the cleaning assembly includes a rotating rod, a deformation plate and a slider. The bottom of the rotating rod is connected to the deformation plate, and a brush layer is fixed on the side of the deformation plate facing the ground. The two ends of the rotating rod are rotatably connected to the slider, and a torsion spring is fixed between the slider and the rotating rod. A sliding groove is opened in the sofa body to accommodate the movement of the slider along the width direction of the sofa body.

[0014] Furthermore, a retraction wheel is rotatably connected to the sofa body, which is fixed to the bottom of the driving wheel. A traction rope is wrapped around the surface of the retraction wheel, and the other end of the traction rope is fixed to the top of the slider. A driven wheel that is against the traction rope is also provided in the sofa body, and an elastic rope is fixed to the slider and the inner wall of the sofa body.

[0015] Furthermore, a plurality of push grooves are provided at both ends of the rotating rod, and a push block matching the push grooves is fixed to the sofa body along the first direction.

[0016] Furthermore, the color-developing layer includes a color-changing layer, a counterweight and a water cavity. A cavity is opened in the color-developing layer, the color-changing layer is located in the cavity, the water cavity is located below the color-changing layer, and the water cavity and the color-changing layer are connected through an opening, and an elastic sealing film is fixed in the opening.

[0017] Furthermore, the color development layer is made of elastic material, and the counterweight is made of metal material.

[0018] Furthermore, a color developing hole is opened at a position of the color developing layer corresponding to the color changing layer, and the color changing layer is made of a color changing silica gel material.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) Compared with the prior art, the present invention can raise the bottom of the sofa body by means of the lifting assembly, thereby keeping it away from the ground, making it convenient for subsequent users to clean the dust under the sofa body, and can also adjust the height of the sofa body cushion, making it more convenient to use. The lifting assembly will drive the cleaning assembly while lifting the sofa, causing the cleaning assembly to move from back to front, thereby automatically cleaning the dust at the bottom of the sofa body through the brush layer, so that the cleaned dust accumulates at the front of the sofa body, thereby saving the user's cleaning time. When the cleaning assembly encounters a heavier object that cannot be cleaned during cleaning, the deformation layer on the cleaning assembly will be deformed by the force, so the color-developing layer will also be deformed. The area where the color-developing layer is deformed will change color, thereby reminding the user, and the deformation layer can shrink, thereby facilitating the user to observe the ground, thereby improving the cleaning effect.

[0022] (2) The output end of the motor will drive the driving wheel to rotate clockwise. The chains engaged on both sides of the driving wheel will rotate synchronously under the drive of the driving wheel, thereby synchronously driving the four lifting cylinders to rotate, so that the four lifting legs can maintain a synchronous lifting effect, thereby increasing the distance between the sofa body and the ground.

[0023] (3) When the retracting wheel rotates, the traction rope will be retracted, thereby generating a pulling force on the slider, causing the slider to drive the deformation plate to slide through the rotating rod. During the movement, the deformation plate will clean the ground through the brush layer, thereby pushing the dust from the back of the sofa body to the front section, making it easier to clean. When the deformation plate moves to the predetermined position, the pushing groove on the rotating rod will contact the pushing block, causing the rotating rod to rotate, thereby driving the deformation plate to rotate and causing the deformation plate to shrink. The shrunken deformation plate will not block the field of view.

[0024] (4) When the color-developing layer is lifted up by an object and deformed, the area of ​​the color-developing layer where it is lifted up will also deform, causing the water cavity in this area to be pressurized and the liquid inside to flow out and be absorbed by the color-changing layer, thus achieving a color change that serves as a good reminder to the user.

[0038] This embodiment 1 will be combined with the disclosed drawings to clearly and completely describe the technical solution, so that the purpose, technical solution and beneficial effects of the embodiment of the present disclosure are more clear. Obviously, the described embodiment is a part of the embodiment of the present disclosure, not all the embodiments. Based on the described embodiment of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this disclosure.

[0039] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the conventional meanings understood by those skilled in the art to which this disclosure pertains. The words “first”, “second” and similar terms used in this disclosure do not indicate any order, quantity or importance, but are merely used to distinguish different components.

When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0040] Example 1:

[0041] The present invention provides a stent with a stretchable deformation structure, see Figure 1-3 , including a sofa body 1, and also including a lifting component 2, a cleaning component 3 and a color-developing layer 4. The lifting component 2 is located at the four corners of the bottom of the sofa body 1, and the lifting component 2 is connected to the sofa body 1, and is used to raise the height of the bottom of the sofa body 1 and the ground. The cleaning component 3 is located at the bottom of the sofa body 1 and is distributed along the length direction of the sofa body 1. The cleaning component 3 is slidably connected to the sofa body 1 and is used to clean the ground. The color-developing layer 4 is installed in the bottom area of ​​the cleaning component 3 and is used to change the color of the area. The lifting component 2, the cleaning component 3 and the color-developing layer 4 are arranged in coordination. When the lifting component 2 lifts the sofa body 1, the lifting component 2 will drive the cleaning component 3 to move to clean the dust, and encountering heavy objects during cleaning will cause the color-developing layer 4 to deform, thereby changing the color of the area.

[0042] Specifically, when in use, the bottom of the sofa body 1 can be raised by the lifting component 2, so that it is away from the ground, making it convenient for the subsequent user to clean the dust under the sofa body 1. The lifting component 2 will drive the cleaning component 3 while lifting the sofa, so that the cleaning component 3 moves from back to front, thereby automatically cleaning the dust at the bottom of the sofa body 1, and the cleaned dust is accumulated at the front end of the sofa body 1, thereby saving the user's cleaning time. When the cleaning component 3 encounters a heavier object during cleaning, the deformable layer on the cleaning component 3 will be deformed, so the color-developing layer 4 will also be deformed. The deformed area of ​​the color-developing layer 4 will change color, thereby reminding the user, thereby improving the cleaning effect.

[0043] See also Figure 4-6The lifting assembly 2 includes a lifting leg, a lifting cylinder 5 and a driving mechanism. The top of the lifting leg is threadedly connected to the lifting cylinder 5, and the top of the lifting cylinder 5 is rotatably connected to the sofa body 1. The driving mechanism is installed inside the sofa body 1 for driving the lifting cylinder 5 to rotate. A limiting slot is vertically opened on the outside of the lifting leg, and a limiting block matching the limiting slot is provided on the sofa body 1. The driving mechanism includes a driving wheel 6 and a chain 7. The chain 7 is provided in two groups, and the two groups of chains 7 are respectively sleeved on the outside of the lifting cylinder 5 along the length direction of the sofa body 1. A gear meshing with the chain 7 is fixed on the outside of the lifting cylinder 5. A driving wheel 6 is installed between the two groups of chains 7. Both groups of chains 7 are meshed with the driving wheel 6. One end of the driving wheel 6 is transmission-connected to a motor, and the end of the driving wheel 6 away from the motor is connected to the cleaning assembly 3.

[0044] Specifically, the motor is connected to the external power supply through a power cord, and the motor can be turned on through the motor switch. The output end of the motor will drive the driving wheel 6 to rotate in the clockwise direction. The chains 7 engaged on both sides of the driving wheel 6 will rotate synchronously under the drive of the driving wheel 6, thereby synchronously driving the four lifting cylinders 5 to rotate. It should be noted that the two sets of chains 7 have opposite rotation directions under the drive of the driving wheel 6, so the screw grooves between the lifting cylinders 5 connected thereto and the lifting legs are also opposite. The screw grooves include positive screw grooves and reverse screw grooves, so that the four lifting legs can maintain a synchronous lifting effect, thereby stably lifting the sofa body 1, thereby increasing the distance between the sofa body 1 and the ground, making it easier for users to clean.

[0045] Among them, the limit slot and the limit block are arranged in combination to limit the lifting leg so that it cannot rotate, thereby effectively ensuring the stability of the vertical sliding of the lifting leg; the motor adopts a servo motor, and its input end is connected to a controller.

[0046] See also Figure 1-3 and Figure 7-10 The cleaning component 3 includes a rotating rod 8, a deformation plate 9 and a slider 10. The bottom of the rotating rod 8 is connected to the deformation plate 9, and a brush layer is fixed on the side of the deformation plate 9 facing the ground. The sliders 10 are rotatably connected at both ends of the rotating rod 8, and a torsion spring is fixed between the slider 10 and the rotating rod 8. A slide groove is provided in the sofa body 1 to accommodate the slider 10 moving along the width direction of the sofa body 1. A retraction wheel 11 is rotatably connected in the sofa body 1. The retraction wheel 11 is fixed to the bottom of the driving wheel 6. A traction rope 12 is wrapped around the surface of the retraction wheel 11. The other end of the traction rope 12 is fixed to the top of the slider 10. A driven wheel that resists the traction rope 12 is also provided in the sofa body 1. An elastic rope 13 is fixed to the slider 10 and the inner wall of the sofa body 1. A plurality of push grooves 14 are provided at both ends of the rotating rod 8. A push block matching the push groove 14 is fixed to the sofa body 1 along the first direction.

[0047] When the sliding plate 10 is moved to the predetermined position, the pushing groove 14 on the rotating rod 8 contacts the pushing block, causing the rotating rod 8 to rotate, thereby driving the deformable plate 9 to rotate and causing the deformable plate 9 to retract, so that the user can clearly observe whether there is dust or other objects on the bottom of the sofa body 1, and the retracted deformable plate 9 will not block the field of view.

[0048] Among them, the deformation plate 9 and the color development layer 4 are both made of elastic rubber material; the brush layer uses nylon brushes; the torsion spring provides torque to the rotating rod 8, so that the rotating rod 8 can automatically recover after being separated from the pushing block, which facilitates the reuse of the deformation plate 9.

[0049] See also Figure 3 and Figure 11 The color-developing layer 4 includes a color-changing layer 15, a counterweight and a water cavity 16. A cavity is opened in the color-developing layer 4, the color-changing layer 15 is located in the cavity, the water cavity 16 is located below the color-changing layer 15, and the water cavity 16 is connected to the color-changing layer 15 through an opening. An elastic sealing film is fixed in the opening. The color-developing layer 4 is made of elastic material, the counterweight is made of metal material, and a color-developing hole is opened in the color-developing layer 4 corresponding to the position of the color-changing layer 15. The color-changing layer 15 is made of color-changing silicone material.

[0050] Specifically, the multiple counterweights in the color-developing layer 4 increase the weight of the color-developing layer 4, so that the color-developing layer 4 can better fit the ground. When the color-developing layer 4 is lifted up by an object and deformed, the lifted area of ​​the color-developing layer 4 will be deformed, so that the water cavity 16 in the area is pressurized and the liquid inside flows out and is absorbed by the color-changing layer 15, so that the color change serves as a good reminder to the user.

[0051] Among them, the color development layer 4 is provided with a water inlet connected to the water cavity 16, and a sealing plug is inserted at the water inlet; a plurality of micropores are provided on the elastic sealing membrane, which are automatically closed under the action of elasticity under normal conditions. When squeezed, the micropores are deformed, causing the liquid inside to flow out.

[0052] Compared with the prior art, the bottom of the sofa body 1 can be raised by the lifting component 2, so that it is away from the ground, which is convenient for subsequent users to clean the dust under the sofa body 1, and the height of the seat cushion of the sofa body 1 can also be adjusted, which is more convenient to use. The lifting component 2 will drive the cleaning component 3 while lifting the sofa, so that the cleaning component 3 moves from back to front, thereby automatically cleaning the dust at the bottom of the sofa body 1 through the brush layer, so that the cleaned dust accumulates at the front end of the sofa body 1, thereby saving the user's cleaning time. When the cleaning component 3 encounters a heavier object that cannot be cleaned during cleaning, the deformable layer on the cleaning component 3 will be deformed by the force, so the color-developing layer 4 will also be deformed. The area where the color-developing layer 4 is deformed will change color, thereby serving as a reminder to the user, and the deformable layer can shrink, thereby facilitating the user to observe the ground, thereby improving the cleaning effect.

[0053] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
