Description

Technical Field

[0001] This utility model relates to the field of living furniture technology, and in particular to a self-rotating buffer mechanism and furniture. Background Technology

[0002] In the modern furniture manufacturing industry, sofas, as an important component of daily home and office environments, have comfort and durability as core concerns for users. Currently, most sofas use a serpentine spring structure as a support component for the seating surface, providing support to the cushion through the elastic deformation of the serpentine spring.

[0003] However, traditional serpentine spring structures have a significant drawback in practical use: insufficient dynamic cushioning. When a user sits down or stands up, the spring quickly collapses or rebounds, lacking an effective dynamic cushioning mechanism. Specifically:

[0004] When sitting down, the serpentine spring sinks too much instantly, causing the user to feel insufficient support;

[0005] When standing up, the serpentine spring rebounds too quickly, generating a noticeable reaction force and reducing comfort.

[0006] Therefore, existing sofas need to be improved to address the problem of insufficient dynamic cushioning.

[0007] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0008] One objective of this invention is to provide a self-rotating buffer mechanism and furniture that can effectively solve the problem of insufficient dynamic buffering in existing sofas.

[0009] To achieve the above objectives, this utility model provides a spin buffer mechanism, comprising:

[0010] A follower lower stud, the lower end of which is rotatably configured about a vertical axis;

[0011] A support stud is provided, the lower end of which is helically connected to the follower stud, and the upper end of which is used to provide upward support.

[0012] A stud spring is located between the two studs and is used to drive the upper stud of the support to move upward relative to the lower stud of the follower.

[0013] Optionally, the lower end of the follower stud is fitted with a rotary bearing, and the upper end of the follower stud is provided with a lower helical part.

[0014] Optionally, the lower part of the upper stud is provided with an upper spiral part that is spirally connected to the lower spiral part.

[0015] Optionally, the bottom surface of the upper spiral portion is provided with a spring limiting ring through which the lower spiral portion passes.

[0016] Optionally, the surface roughness of the inner wall of the spring limiting ring is less than the surface roughness of the outer wall of the spring limiting ring.

[0017] Optionally, the upper spiral portion and the spring limiting ring are integrally formed, or the upper spiral portion and the spring limiting ring are welded and fixed.

[0018] Optionally, the stud spring is sleeved on the lower helical portion;

[0019] Furthermore, the upper end of the stud spring abuts against the bottom surface of the spring limiting ring, and the lower end of the stud spring abuts against the top surface of the inner ring of the rotary bearing.

[0020] Optionally, the top of the support stud is provided with a horizontal support plate.

[0021] On the other hand, a type of furniture is provided, including:

[0022] Furniture base;

[0023] An elastic support member, located above the furniture base, is used to provide upward elastic support to the human body;

[0024] In any of the aforementioned spin buffer mechanisms, the follower lower stud of the spin buffer mechanism is rotatably mounted relative to the furniture base around a vertical axis, and the support upper stud of the spin buffer mechanism is fixedly mounted to the bottom of the elastic support member.

[0025] Optionally, the furniture may be a sofa or a bed frame.

[0026] The beneficial effects of this utility model are: it provides a self-rotating buffer mechanism and furniture.

[0027] (1) When the user sits down, the elastic support is compressed and sinks, pushing the upper stud of the support downward. At this time:

[0028] ① The stud spring is compressed to store energy;

[0029] ② The helical engagement between the upper support stud and the lower follower stud converts the linear downward pressure into the rotational motion (forward rotation) of the lower follower stud, and the kinetic energy is consumed by the friction damping of the threads;

[0030] ③ The sinking speed of the elastic support is slowed down due to energy conversion, thus avoiding instantaneous collapse.

[0031] (2) When the user stands up, the stud spring releases its stored energy, pushing the upper stud of the support upwards. At this time:

[0032] ①The stud compression spring drives the stud to reverse, and the rebound kinetic energy is absorbed by the rotational damping.

[0033] ② The elastic support slowly resets to avoid the impact caused by rapid rebound.

[0034] Therefore, the self-rotating buffer mechanism and furniture provided by this utility model can effectively solve the problem of insufficient dynamic buffering in existing sofas. Attached Figure Description

[0051] This invention provides a self-rotating buffer mechanism and furniture, which can effectively solve the problem of insufficient dynamic buffering in existing sofas.

[0052] See Figure 1 The furniture provided in this embodiment includes:

[0053] Furniture base 1;

[0054] Elastic support 2, located above the furniture base 1, is used to provide upward elastic support to the human body;

[0055] Spin buffer mechanism 4, located below the elastic support 2, is used to provide upward support to the elastic support 2.

[0056] In this invention, the furniture can be a sofa or a bed frame, or other furniture that needs to provide elastic support for the human body. When used as a sofa, the elastic support 2 serves as the seating support; when used as a bed frame, the elastic support 2 serves as the bed frame slats. This invention does not limit the specific use of the furniture.

[0057] Furthermore, see his 2 and Figure 3 The spin buffer mechanism 4 includes:

[0058] Follower stud 401, the lower end of which is rotatably mounted relative to the furniture base 1 about a vertical axis;

[0059] The upper support stud 402 is provided, the lower end of which is helically connected to the lower follower stud 401, and the upper end of which is connected to the bottom of the elastic support member 2 to provide upward support.

[0060] A stud spring 403 is located between the two studs and is used to drive the upper support stud 402 to move upward relative to the lower follower stud 401.

[0061] The working process of the self-rotating buffer mechanism 4 and the furniture provided by this utility model is as follows:

[0062] (1) When the user sits down, the elastic support 2 is compressed and sinks, pushing the upper stud 402 of the support downward. At this time:

[0063] ① The stud spring 403 is compressed to store energy;

[0064] ② The helical engagement between the upper stud 402 and the lower stud 401 converts the linear downward pressure into the rotational motion (forward rotation) of the lower stud 401, and the kinetic energy is consumed by the friction damping of the threads.

[0065] ③ The sinking speed of the elastic support 2 is slowed down due to energy conversion, thus avoiding instantaneous collapse.

[0066] (2) When the user stands up, the stud spring 403 releases its stored energy, pushing the upper stud 402 of the support upward. At this time:

[0067] ① The stud spring 403 drives the stud 401 to reverse, and the rebound kinetic energy is absorbed by the rotational damping.

[0068] ② The elastic support 2 slowly resets to avoid the impact caused by rapid rebound.

[0069] Therefore, the self-rotating buffer mechanism 4 and furniture provided by this utility model can effectively solve the problem of insufficient dynamic buffering in existing sofas.

[0070] In this embodiment, the lower end of the follower lower stud 401 is fitted with a rotary bearing 404, and the upper end of the follower lower stud 401 is provided with a lower helical portion 4011. The lower part of the supporting upper stud 402 is provided with an upper helical portion 4021 that is helically connected to the lower helical portion 4011. Further, the bottom surface of the upper helical portion 4021 is provided with a spring limiting ring 4022 through which the lower helical portion 4011 passes. The stud compression spring 403 is fitted on the lower helical portion 4011; and the upper end of the stud compression spring 403 abuts against the bottom surface of the spring limiting ring 4022, and the lower end of the stud compression spring 403 abuts against the top surface of the inner ring of the rotary bearing 404.

[0071] The follower lower stud 401 is mounted at the bottom of the adjustment cavity via a rotary bearing 404, ensuring free rotation under the elastic force of the stud spring 403 and avoiding the jamming problem caused by friction in traditional structures. The mating design of the upper helical part 4021 and the lower helical part 4011 converts linear motion into rotational motion, making the buffering process smoother. This separate structure also facilitates the replacement of individual components during maintenance. The spring limiting ring 4022 not only provides a stop for the stud spring 403 but also effectively limits the axial working position of the follower lower stud 401, ensuring that the follower lower stud 401 always maintains a helical engagement with the supporting upper stud 402 during rotation.

[0072] Optionally, the top of the upper stud 402 is provided with a horizontal support plate 4023 for upwardly supporting the elastic support member 2. The horizontal design of the horizontal support plate 4023 can ensure that the reaction force of the elastic support member 2 on the upper stud 402 is vertically downward along the axis of the upper stud 402, avoiding the upper and lower studs from getting stuck due to the biased reaction force.

[0073] Optionally, the surface roughness of the inner wall of the spring limiting ring 4022 is less than the surface roughness of the outer wall of the spring limiting ring 4022. During rotation, the follower stud 401 easily comes into contact and rubs against the inner wall of the spring limiting ring 4022. Keeping the surface roughness of the inner wall of the spring limiting ring 4022 to a smaller value helps improve the smoothness of the inner wall, reducing frictional resistance, minimizing wear on parts caused by friction, and extending service life. Relaxing the surface roughness requirement for the outer wall of the spring limiting ring 4022 can reduce processing costs.

[0074] In this embodiment, the upper spiral portion 4021 and the spring limiting ring 4022 are integrally formed, or the upper spiral portion 4021 and the spring limiting ring 4022 are welded and fixed.

[0075] The one-piece molding structure can reduce the number of weld points and improve the connection strength. Welded connection allows for the prior surface treatment of the inner wall of the spring limiting ring 4022, such as polishing and grinding, to make the surface roughness of the inner wall of the spring limiting ring 4022 meet the requirements before welding it to the upper spiral part 4021, thus reducing the difficulty of the surface treatment process.

[0076] Optionally, in order to further ensure that the upper spiral part 4021 and the lower spiral part 4011 do not shift radially, a sleeve (not shown in the figure) can be provided on the outside of both the upper spiral part 4021 and the lower spiral part 4011. It is understood that adding a sleeve can also serve as a dust protection function.

[0077] In summary, the spin buffer mechanism 4 and the furniture provided in this embodiment have the following advantages:

[0078] ① Dynamic buffer optimization: The linear pressure is converted into rotational motion through the spiral connection, and the kinetic energy is consumed by the thread friction damping, which effectively slows down the sinking speed of the elastic support 2 and avoids instantaneous collapse.

[0079] ② Smooth rebound control: The energy storage of the stud spring 403 drives the follower stud 401 to reverse, and the rotational damping absorbs the rebound kinetic energy, so as to realize the slow reset of the elastic support 2 and prevent rapid impact.

[0080] ③ Reliable axial positioning: The spring limit ring 4022 restricts the working position of the follower lower stud 401, ensuring that the helical engagement is always effective, and at the same time provides a stop for the stud compression spring 403.

[0081] ④ Reduced friction loss: The low roughness treatment of the inner wall of the 4022 spring limit ring reduces contact friction and extends the service life of the parts, while the requirements for the outer wall are relaxed to save costs.

[0082] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
