Description

[0001] Technical Field: This invention relates to the field of intelligent electromechanical furniture, and more particularly to a rocking reclining chair; Background Technology

[0002] The rocking chair, an ancient toy originating from our ancestors who used curved tree trunks bound together to form a swinging frame for amusement, has evolved over thousands of years into countless forms. Its presence is felt in every corner of the world, and its unique rocking motion has always embodied people's yearning for relaxation, comfort, elegance, and even carefree spirit. However, throughout its long development, it has consistently struggled to overcome a fundamental technological barrier—"it can rock, but it cannot rock freely and continuously."

[0003] This shortcoming not only makes it extremely inconvenient to use, but also greatly hinders the rocking chair's highly beneficial health, relaxation, and wellness features. For centuries, the rocking chair has been a garden pet of the upper class. Because it cannot rock itself, a nanny or servant could take over the rocking, allowing the owner to enjoy the beneficial experience of "leisurely and deep sleep" provided by the rocking chair. This is why they affectionately called the rocking chair "leisure chair," "divine chair," or "comfort chair." It is precisely this upper-class perception and tradition that has allowed this uniquely rocking ancient creature to continue. For the general public, the rocking chair, because it cannot rock itself, offers an experience even less enjoyable than a regular chair. This predicament is not only a regret for a certain social group, but also a deficiency in society as a whole.

[0004] In the era of automation, the global industry attempted to solve this problem. While no better solution was found, a number of "track-type," "spring-type," and "base-type" electric rocking chairs emerged. These "base-type electric rocking chairs" were innovative achievements by innovators who, unable to automate the rocking chair with curved legs, had to bypass the curved legs and find alternative paths. However, while these innovative products achieved "self-rocking," their swaying was based on a fixed base and performed mechanical movements with a "fixed frequency" and "fixed amplitude." Unfortunately, this mechanical swaying motion only had the action of "rocking" but lacked the free swaying spirit of a rocking chair. Obviously, this mechanical reciprocating swaying does not conform to the "natural freedom and carefree" nature of a rocking chair, and its health-preserving aesthetic experience is difficult for the world to accept.

[0005] The "curved-leg rocking chair" can be said to conform to the laws of nature. Because the rocking pattern of the curved-leg rocking chair contains a special law of "linear focus and planar trajectory", it is this unique law that gives the rocking chair the excellent rocking performance of "natural, free, carefree, comfortable and elegant". It is also because of this unruly free rocking characteristic that countless skilled craftsmen in the industry have been unable to master it for more than half a century. As a result, the "automation" of rocking chairs has been forced to take a detour, resulting in a long-term technological gap in this field.

[0006] This invention, through in-depth analysis of the unique motion laws of rocking chairs and following the first principles of rocking chair movement, independently developed a "harmonic oscillation technology." This technology fundamentally conforms to the free swaying nature of "circular foot rocking," solving the world problem of rocking chairs being unable to "sway on their own" for thousands of years. It ends the history of rocking chairs relying on hand cranking for thousands of years, transforming the "leisure chair," a science fiction object that the ancients dreamed of, from a cultural concept into a high-quality technological product. Furthermore, it builds upon this peak by creating a work and study table, elevating the leisure chair to a new level. It becomes a multi-functional leisure chair that combines reclining, sitting, leaning, lying down, leisure, relaxation, health care, wellness, work, and study, and is hailed as the "Leisure Throne."

[0007] Prior to this invention, this field was nonexistent. Summary of the Invention

[0008] The purpose of this invention is to completely overcome the technical obstacle of rocking chairs, which have existed for thousands of years, being unable to rock on their own. This would allow the natural properties that are extremely beneficial to people's leisure, health, and wellness to be fully released, transforming the chair into a versatile and comfortable reclining and sitting device. This device would provide people with a comfortable and relaxing space for leisure, relaxation, health care, wellness, work, and study, allowing them to freely lie down, sit, lean back, or recline, and freely adjust the comfort of all joints. It would also eliminate a series of adverse physiological and psychological problems that easily arise from prolonged sitting or lying down during leisure or work, such as lower back pain, stiff neck, joint discomfort, limb fatigue, leg swelling, poor blood circulation, premature aging of vision, and even anxiety and insomnia. This invention offers a comfortable and relaxing seat that protects the body's health, ensuring long-term comfort without fatigue.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] Technical solution:

[0011] To overcome the shortcomings of the two existing rocking chairs, namely that "the curved foot rocking chair cannot rock continuously" and "the fixed base rocking chair cannot rock freely", the present invention provides a reclining chair, including: a rocking frame (1) and a reclining cabin (2); the reclining cabin (2) is located on the upper part of the rocking frame (1).

[0012] The rocker frame (1) includes a frame (11), an arc-shaped rocker foot (12), and a drive unit (13).

[0013] The frame (11) is a rigid plate hollow structure with several structural holes for the internal and external peripheral components of the structure, and is fixed with multiple structural components (14); its lower edge is fixed with an arc rocker foot (12) that rolls against the ground to support the swing; the frame (11) is a left-right symmetrical structure, and the two sides of the frame are fixed together by a support rod (15); the bottom of the swing frame (1) is provided with a driver (13) between it and the ground to drive the swing body to swing when necessary.

[0014] The reclining cabin (2) includes a backrest mechanism (21), a seat board (22) and a leg support mechanism (23);

[0015] The backrest mechanism (21) includes a backrest body (211), a backrest bracket (212), and a backrest lifter (T213); the backrest mechanism (21) is rotatably mounted on the structural member (14) of the rocking frame (1) via the backrest bracket (212); and is supported on the corresponding hole on the rocking frame (1) via the live connecting pin (T16) of the backrest lifter (T213);

[0016] The seat plate (22) is located in the middle of the rocking frame (1) and is fastened to the structural member (14) through a pre-set fastening notch; the seat plate (22) is configured such that the rear end is lower than the front end; the rear end of the seat plate (22) is hinged to the backrest mechanism (21) through the structural member (14); the front end is hinged to the leg support mechanism (23) through the structural member (14);

[0017] The leg support mechanism (23) is set on the structural member (14) at the front end of the swing frame (1), and is rotatably extended and connected to the swing frame (1). It is supported on the corresponding hole on the swing frame (1) by the live connecting pin (T16) of the leg lifter (T2331).

[0018] The oscillating actuator (13) is an indirect intermittent harmonic technology oscillating actuator, including: an indirect power compensation actuator (131) and a harmonic technology electronic control system (132); the indirect power compensation actuator (131) is electrically connected to the harmonic technology electronic control system (132) and is used to control the indirect power compensation actuator (131) to intermittently output indirect compensation power to the oscillating frame (1) to assist the oscillating body to oscillate freely and continuously.

[0019] The indirect intermittent power compensation actuator (131) includes a housing (1311) and a power output transmission assembly (1313); the housing (1311) also includes a drive motor (1312) housing; the housing (1311) is fixedly connected to the swing frame (1), but the power output transmission assembly (1313) is indirectly connected to the swing frame (1).

[0020] The harmonic technology electronic control system (132) includes: a control center module (1321), an attitude sensing device (1322), and a human-machine interaction component (1323).

[0021] The attitude sensing device (1322) is connected to the control center module (1321) for real-time monitoring of the swaying motion state of the swing frame (1) and sending a phase signal containing the start-up time point (TO1) to the control center module (1321); the human-machine interaction component (1323) is connected to the control center module (1321) for setting the swaying mode.

[0022] The transmission assembly (1313) includes a worm gear mechanism (13131), a worm shaft (13132), a clutch (13133), a drive arm (13134), and a ground roller (13135). The worm gear mechanism (13131) is located at the lower end of the drive motor (1312) and is connected to the power output end of the drive motor (1312). The worm shaft (13132) is coaxially connected to the worm of the worm gear mechanism (13131) and passes through the corresponding shaft hole on the rocker frame (1). A bearing is installed between the shaft hole and the shaft and is movably connected to the bearing of the rocker frame (1). Both the inner and outer ends of the bearing are provided with clips. The ring is locked to prevent axial movement; the active rotor of the clutch (13133) is sleeved on the worm gear shaft (13132) and fixedly connected to the worm gear shaft (13132) with a pin key, and rotates together; the passive rotor of the clutch (13133) is fixedly connected to the shaft hole of the drive arm (13134) and is engaged and disengaged from the active rotor of the clutch; the active rotor of the clutch (13133) is controlled by the harmonic technology electronic control system and intermittently drives the drive arm (13134). The ground end of the drive arm (13134) is equipped with a ground roller (13135) that rolls in contact with the ground, forming an indirect intermittent transmission structure.

[0023] The leg support mechanism (23) includes a leg rest (231), a foot rest (232), and an extension mechanism (233); the extension mechanism (233) includes a lifter (T2331) and a geometrically variable triangle (2332) and an isosceles quadrilateral (2333); the leg rest (231) and the foot rest (232) are located on the upper part of the extension mechanism and are extended and retracted by the lifting drive of the lifter (T2331).

[0024] The leg lift (T2331) is interchangeable with the backrest lift (T213) and includes: a lift motor (T11), a hexagonal drive shaft (T12), a lift screw reversing head (T13), a lift screw (T14), a square support tube (T15), a lift screw nut seat (T16), and a connecting pin (T17).

[0025] The lifting motor (T11) is fixed to the underside of the leg support plate (231) by a motor bracket; the other end is the power output end, which is connected to the middle section of the hexagonal drive shaft (T12);

[0026] The hexagonal drive shaft (T12) is the connecting pivot between the lifting device (T2331) and the lifted component. It is symmetrically connected to the lifting screw reversing head (T13) and the lifted component (the legs are leg rests (231) and the backrest bracket (212)).

[0027] The upper end of the lifting screw (T13) is rotatably connected to the lifting screw reversing head (T14). The internal structure of the reversing head has two pairs of bevel gears meshing at 90°, which can reverse the rotational power by 90° and transmit it to another transmission component.

[0028] The lower end of the lifting screw (T13) is fitted with a lifting screw nut seat (T17), which is fixed on the square support tube (T15). The two ends of the square support tube (T15) are connected to the rocker frame (1) by a movable connecting pin (T16). Therefore, the position of the nut seat (T17) is slightly rotatable and relatively fixed. Thus, the lifting screw (T13) can only rise or fall with the nut seat (T17) as the base point, and through the lifting screw reversing head (T14), it drives the lifted parts connected to both ends of the hexagonal drive shaft (T12) to rise or fall. The lifted parts are connected to both ends of the hexagonal drive shaft (T12) through miniature bearings, and the bearings are locked and limited by locking rings.

[0029] The limit switch (T18) has two bidirectional contacts corresponding to the two poles and is fixed to each other on the side of the lifting screw nut seat (T16); the limit retaining ring (T19) is fixed at both ends of the lifting screw (T13) and moves together with the lifting screw (T13) to trigger the limit switch so that the control system can obtain the preset lifting limit position signal.

[0030] The technical solution also includes a work and study table (3), which is located above the front of the reclining cabin (2) and is detachably connected to the rocking frame (1), and is configured to be relatively adjustable and rock synchronously with the rocking frame (1).

[0031] As a key technical point: the deployment of the structural holes on the rocking frame (1) is of profound significance. The system center of gravity Go is the coupling point of various energies such as potential energy, kinetic energy, inertial force, and driving force, which makes this reclining chair uniquely possess zero-damping self-swaying performance and can provide valuable performance of not being tired after sitting for a long time by feeding back positive spiritual and physical energy to the rider.

[0032] As a key technical point: the arc rocker foot (12) has a preset radius of curvature, the radius of curvature R is limited to 710-1010mm, the chord length L is limited to 800-1280mm, and the arc can be a single-centered arc or multiple tangentially coupled arcs.

[0033] As a key technical point: the rocking actuator (13) is the core drive assembly of the present invention, which is matched with the human chair potential energy harmonic self-rocking mechanism to form a perfect rocking system that integrates human and machine and combines rigidity and flexibility.

[0034] As a key technical point: the backrest mechanism (21) is configured to be infinitely adjustable from vertical to rearward tilting 0-<90°; used to adjust the upper body posture and the relative position of the center of gravity G1 and the system center of gravity Go, so as to adjust the swaying performance in real time.

[0035] As a key technical point: the seat plate (22) is configured to be higher in the front and lower in the back to adapt to the swaying working characteristics, with a drop of 50mm-115mm, so as to fit the curve of the human buttocks and avoid the buttocks from being displaced and worn during swaying.

[0036] As a key technical feature: the leg support mechanism (23) is a two-stage composite linkage structure designed for special leg movement postures. It can initially place the legs in a hinged angle position, and through a large tilting angle extension mechanism, reshape them into a straight, upward-pointing posture in space, ultimately lifting the legs to a preset height where the soles of the feet are slightly above the heart level. This design also adjusts the deep health benefits of the rocking chair. With the feet at this height, they can not only form an optimal comfortable leaning posture of approximately 112±5° with the upper body, but also improve blood circulation in the legs and internal organs, achieving the goal of quickly relieving leg fatigue.

[0037] As a key technical feature, the reclining cabin (2) is configured with a multi-link linkage adjustment mechanism. It can adjust the leaning angle of the upper body and the lifting angle of the legs and feet. While adjusting the overall comfort angle, it also adjusts the swaying performance of the swaying body. This is an autonomously adjustable adaptive comfort system that responds to the expansion and contraction adjustment of the swaying performance. It can independently execute the support angle, height and length of the legs and upper body, and can also adjust the overall posture with one click.

[0038] As a key technical feature, this seating is also equipped with a chair potential energy harmonic self-swaying mechanism. This mechanism is based on a series of scientific theories, such as the fact that swaying motion is a "swaying wave" with a four-phase cycle of "starting momentum, generating momentum, retracting momentum, and accumulating momentum" in both directions, and that there are "potential energy phase differences" and "velocity phase differences" between the person and the seat during swaying. The human body, as a natural dynamic energy body, is integrated into the entire motion system as a dynamic factor affecting swaying. This system is precisely coupled with the overall structural parameters to form a zero-damping coefficient system, ultimately constructing the chair potential energy harmonic self-swaying mechanism.

[0039] The core technology of this invention is the successful development and application of harmonic oscillation technology. "Without harmonic technology, there would be no free and continuous oscillation of the rocking chair." It has fundamentally changed the oscillation mode of the arc-shaped rocking chair and fundamentally solved the global problem that the arc-shaped rocking chair cannot oscillate continuously. The harmonic oscillation technology is specifically applied to the "indirect intermittent harmonic technology driver (13)" and the "human chair potential energy harmonic self-oscillation mechanism" of this invention; the indirect intermittent harmonic technology oscillation driver (13) controls the indirect kinetic energy compensation actuator (131) through the harmonic technology electronic control system (132) to give the oscillating body an indirect influence thrust in each oscillation cycle, following the waveform of the oscillation wave (called harmonics). Its working principle is: at the appropriate time and place, apply an appropriate force to the oscillating body (push and release) and let the rocking chair continue to oscillate freely, so this recliner can achieve continuous free oscillation; the indirect harmonic technology driver has similar effects to a mother rocking a baby, with the characteristics of quickly inducing sleep, assisting deep sleep, and quickly replenishing energy; while the human chair potential energy harmonic self-oscillation The mechanism utilizes the natural energy of the human body. When sitting in the rocking chair, the human body sways with the rocking wave (harmonic waves). As long as one does not intentionally move against the potential energy, the human body, as a flexible body, experiences a "phase lag" in each swaying stroke with the rigid rocking chair. This is called "potential energy phase difference" and "velocity phase difference." These potential energy phase differences and velocity phase differences will cause the rocking chair and the human body, which are natural energy bodies, to have a mutually stimulating effect. This effect will directly cause the rocking chair to continuously rock (details of the specific implementation method are described). The human-chair potential energy harmonic self-rocking mechanism has the characteristics of activating brain thinking, relaxing physical cells, and promoting pleasant emotions. During the process of the human body and the rocking chair rocking together with harmonic waves, the rocking motion has the characteristics of feeding back mental pleasure and physical energy to the human body. Therefore, the rider can sit for a long time without feeling tired while rocking. The characteristics of the two oscillation mechanisms mentioned above are naturally compatible, just like a couple in a family, the hermaphroditism of a creature, the perfect match of things, and the synergy of working conditions. Together, they enhance the unique wisdom, perfection, and numerous advantages of this reclining chair.

[0040] The beneficial effects of this invention are:

[0041] Overcoming the technical obstacle that has prevented rocking chairs from rocking freely and continuously for thousands of years, the technical performance of rocking devices with curved feet has directly leaped from the hand-cranked era to the era of carefree ease.

[0042] It has opened up a wide range of application scenarios: With the removal of technical obstacles to rocking chairs, the leisure, health and wellness properties of rocking chairs that are extremely beneficial to human beings have been fully released, thus opening up a wide range of application scenarios for people to deeply develop and utilize the rocking properties of the curved footrests.

[0043] It created universal benefits: By clearing away the technical obstacles of the curved rocking feet, the rocking chair, a masterpiece of nature that for thousands of years belonged to the homes of the rich and noble, while the general public could only "smell its fragrance and look at its appearance but could not enjoy its benefits," has now entered the homes of ordinary people.

[0044] Fulfilling the world's dream of carefree living: The ancients bestowed the beautiful name of carefree living upon the rocking chair, but this sci-fi marvel, like a dream of carefree living that has lingered for millennia, remained unfulfilled. This invention, however, finally brings this wish to fruition.

[0045] Elevating the quality and aesthetics of the entire category of rocking devices: By overcoming the technical obstacles of curved footrests and with the new support of modern manufacturing technology, this reclining device will change its previous stale state and become a modern lifestyle item with a high-tech appearance that everyone loves.

[0046] Enhanced Body Support: The unique swaying motion aesthetic design precisely supports the body's curves under different usage needs, providing a perfect support experience.

[0047] Excellent comfort experience: The ability to freely switch between various postures such as lying down, sitting, leaning, and reclining, and the ability to fine-tune comfort, can prevent fatigue caused by maintaining a single posture for a long time, making every posture comfortable and worry-free at all times.

[0048] A unique and relaxing experience: Lying back and forth on this rocking device will naturally bring forth a wonderful and carefree mood, allowing you to fantasize about outer space, contemplate life, enjoy the present moment, and imagine the future...

[0049] A series of superior functions: a living tool that integrates multiple functions such as leisure, health preservation, health care, rehabilitation, work, and study, as well as multiple postures such as lying down, sitting, leaning, and reclining. It achieves full-time and space-time scene coverage and functional integration of the human body, breaking the physical boundaries between life, work, leisure, and health preservation.

[0050] Numerous and significant beneficial effects: Swaying is a universally acknowledged and enjoyable activity for people of all ages. Everyday swaying activities (such as swinging) offer countless benefits, such as improved blood circulation, increased dopamine levels, and clearer, more focused thinking. When swaying is integrated into a complete energy-boosting system through a unique aesthetic, its beauty is fully revealed, resulting in a more significant effect on boosting mood and vitality. It also promotes harmony between the body and nature, stimulates the secretion of dopamine and other pleasure hormones, increases brain oxygen supply, activates the vestibular system in the inner ear, improves sleep quality, enhances blood circulation, lowers heart rate and blood pressure, alleviates anxiety and restlessness, and aids in physical and emotional regulation. Prolonged swaying leads to smoother bodily functions, gradually creating a sustained positive energy state beneficial to health and longevity.

[0051] Nourishing Body and Mind: This invention provides a unique dynamic aesthetic through continuous, natural, and comfortable swaying that aligns with the body's physiological rhythms. Whether in work, study, or leisure settings, this device effectively relieves mental and physical stress and brings pleasant emotional benefits through its unique swaying motion feedback.

[0052] Health Benefits: The comfortable reclining posture combined with the rhythmic swaying motion effectively improves the distribution of force and blood circulation in the body during prolonged sitting or lying down. Functionally, it prevents a series of adverse physiological and psychological effects that are easily caused by prolonged sitting, lying down, leisure, or work, such as lower back pain, stiff neck, joint discomfort, limb fatigue, leg swelling, poor blood circulation, visual fatigue, vision impairment, and even anxiety and insomnia. It provides thoughtful care for the whole body's health. Its carefree and comfortable characteristics, which allow for prolonged sitting without fatigue, are a great benefit, especially for those who work, study, or take time off to maintain their health.

[0053] Fatigue Replenishment: When the body's energy is depleted (such as after returning from an outing or after a long period of exertion at home) and one is fatigued, a good night's sleep is essential to replenish energy. Simply sit in the rocking chair and activate the harmonic drive rocking mechanism via voice or touch. The chair will rock like a mother rocking a baby, quickly helping the body enter a state of deep sleep. According to the laws of nature, the body absorbs energy from nature during deep sleep, rapidly replenishing energy. Upon waking, fatigue will be gone and you will feel refreshed.

[0054] Clean, environmentally friendly, healthy, and low-energy consumption: The unique human-chair potential energy harmonic self-swaying mechanism of the reclining chair is an energy-free mechanism. This swaying mode can meet the needs of most people in most daily use scenarios and times, making this highly used household appliance almost free of negative energy consumption.

[0055] Prolonged sitting without fatigue: When the body needs to work, study, or simply relax and enjoy life, sitting in this reclining chair allows it to rock back and forth. This natural rocking provides a significant boost of positive energy to the body's mental and emotional well-being, making the user feel increasingly energetic, clear-headed, relaxed, and cheerful. The more the chair rocks, the less tired the user becomes (healthy individuals can sit for over 5 hours without feeling fatigued). This feature provides an extremely comfortable and relaxing micro-Tai Chi-like environment for workers, students, and those seeking leisure.

[0056] Technical contributions of this invention:

[0057] It revealed the core principles of rocking chair movement, which were previously little known and not recorded in any literature;

[0058] This reveals the fundamental technical obstacle that makes it difficult to automate rocking chairs: their inherent tendency to sway freely + linear focal point 0q-0-0h;

[0059] It reveals that the energy of the swaying motion originates from the potential energy inherent in the unique structure of the swaying body. The reason why it can sway back and forth is because it has a back-and-forth oscillation mechanism, rather than external energy. Therefore, it is a clean and healthy energy body with no negative energy consumption.

[0060] It reveals that the reason why swaying exercise has the functions of health preservation, sleep aid and fitness is that the essence of swaying is that swaying has a constantly refreshing and cleansing effect on thinking, and a physical stimulating effect on the body's cells. Therefore, it has the functions of refreshing thoughts, making people focus, adjusting emotions, soothing the mind, relaxing muscles and promoting blood circulation, and strengthening the body. It allows people to temporarily forget the negative energy mood at this moment with joy and peace.

[0061] It reveals the physical phenomena of "potential energy phase difference" and "velocity phase difference" in the rocking chair, thus accurately creating the idea that "the rocking chair can establish mutual excitation with the rocking subject to achieve a self-rocking mechanism."

[0062] The phenomenon of oscillating motion was first defined as a concept of "oscillating wave";

[0063] We have developed an indirect intermittent harmonic oscillation technology and driver specifically designed for the continuous self-oscillation of a circular arc oscillating body.

[0064] The system has systematically established the motion theory, control methods, and implementation examples of swaying motion, and created a fully functional Xiaoyao product.

[0065] This invention has entered the practical application stage. Attached Figure Description

[0106] Detailed Implementation

[0107] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be analyzed in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the examples of this invention, and not all of them. This invention is applicable to all reclining devices, and reclining cabins are also applicable to similar functions such as therapeutic equipment; the components of the embodiments described and shown in the accompanying drawings can be arranged and designed in different configurations. Therefore, the following embodiments are only used to explain this invention, and not to limit the scope of this invention. Based on the embodiments of this invention, other similar implementation methods obtained by those skilled in the art without creative effort are all within the scope of protection of this invention.

[0108] This invention uses the reclining chair as an example to explain the implementation method in detail, such as... Figures 1 to 14 As shown, a series of embodiments of the present invention are systematically illustrated:

[0109] Example 1: Shaking Body Example

[0110] like Figure 2As shown, the present invention provides a reclining chair, which mainly includes a rocking frame (1), a reclining seat (2), and an ergonomic table (3).

[0111] The swing frame (1) serves as the support for the entire machine, with symmetrically arranged arc-shaped rocker feet (12) on both sides of its bottom. The bottom of the arc-shaped rocker feet (12) abuts against the ground, forming a swing fulcrum. Between the swing frame (1) and the ground, an indirect intermittent intelligent harmonic technology swing actuator (13) is constructed. This actuator transmits power to the swing body indirectly, and the electronic control system is equipped with harmonic control drive technology to indirectly influence the swing energy replenishment of the swing frame (1). Simply put, the power is transmitted to the swing frame using the ground reaction force, and the force application strategy is to control the timing and intensity of the force application to drive the swing body through harmonic control technology. In this embodiment, the moment when the harmonic actuator intervenes to apply force is the zero point of the swing phase from the "accumulation phase" to the "starting phase", and the force application intensity is the difference between the swing angular velocity of the swing body and the rotational angular velocity of the drive arm.

[0112] Skeleton (11) Example: such as Figure 4 It is made of tubular steel welded together or rigid plate hollowed out, or it can be made of other alloys or carbon fiber integrally cast. It has structural holes and four structural components (14) fixed in front, back, left and right. The upper edge can be equipped with a handrest, or it can be customized to be without a handrest, or with a handrest on half, or other irregular shapes to meet the needs of different users; the lower edge is fixed with an arc rocker foot (12). In this embodiment, it is made of rigid plate with a thickness of 3.5-4mm hollowed out, and its shape is an upper arch and a lower crescent shape.

[0113] Circular rocker foot (12) Example: As Figure 3 The circular arc rocker foot (12) is a rocking component that rolls in contact with the ground. It is made of high-strength rigid tubing such as carbon steel or aluminum alloy through cold bending or hot bending processes, or it can be cast as a whole with the frame. It is symmetrically fixed to the lower edge of the frame (11) and connected to form a rocking frame (1) by multiple fixed support rods (15). Its preset radius of curvature R is limited to the range of 710-1010mm, and the chord length L is limited to the range of 800-1280mm. The limitation of this parameter range is based on the balance between rocking stability and sensitivity, and is obtained through repeated experiments. When the radius of curvature is less than the threshold, the rocking sensitivity increases significantly, the rocking controllability decreases, and it is easy to cause the safety hazard of back tipping. When the radius of curvature R is greater than the threshold of 1010mm, the ratio of chord length to radius of curvature increases, the rocking rate slows down, and the rocking response exhibits hysteresis characteristics, which will significantly reduce the user's relaxed and pleasant experience and make it difficult to maintain continuous rocking.

[0114] Although the arc-shaped rocker foot is a common component in existing technology, there has been no scientific definition or design specification for it, nor have there been any products on the market that have been recognized for their excellent design performance. This invention defines the arc-shaped rocker foot as a highly sensitive response component of the arc-shaped rocker body, preferably with a radius of curvature R of 840mm and a chord length L of 1050mm; and it is fixed to the bottom of the rocker frame using high-quality round steel pipe and welding process. In other embodiments, it can also be integrally cast or integrally cut with the frame (11).

[0115] It should be noted that the above numerical range is an optimized range based on standard adult body size data. The values ​​may differ for a specific population, but as long as the design geometric parameters fall within or are equivalent to the above range, they should fall within the protection scope of this application.

[0116] Example 2: Indirect intermittent intelligent harmonic technology oscillating actuator (13) Example:

[0117] like Figure 5 — Figure 5c As shown, Figure 5 The indirect intermittent intelligent harmonic technology drive actuator (13) comprises: an indirect kinetic energy compensator (131) and a harmonic technology electronic control system (132). The indirect kinetic energy compensator (131) is configured such that its housing is fixed to the oscillating body, and the power transmission path is transmitted to the oscillating body via ground reaction force, such as... Figure 5bAs shown. Its transmission assembly (1313) includes a worm gear mechanism (13131), a worm shaft (13132), a clutch (13133), a drive arm (13134), and a ground roller (13135); the worm gear mechanism (13131) is located at the lower end of the drive motor (1312) and is connected to the power output end of the drive motor (1312); the worm shaft (13132) is coaxially connected to the worm of the worm gear mechanism (13131) and passes through the corresponding shaft hole on the rocker frame (1), and a bearing is installed between its shaft hole and the shaft, which is movably connected to the bearing of the rocker frame (1); both the inner and outer ends of the bearing are provided with The retaining ring is locked to prevent axial movement; the driving rotor of the clutch (13133) is sleeved on the worm gear shaft (13132) and fixedly connected to the worm gear shaft (13132) with a pin key, and rotates together; the driven rotor of the clutch (13133) is fixedly connected to the shaft hole of the drive arm (13134) and is engaged and disengaged from the driving rotor of the clutch; the driving rotor of the clutch (13133) is controlled by the harmonic technology electronic control system and intermittently drives the drive arm (13134). The ground contact end of the drive arm (13134) is equipped with a ground roller (13135) that rolls in contact with the ground, forming an indirect intermittent transmission structure.Working state of the rocking actuator (13): Although the rocking actuator (13) and the rocking body are integrated, their operation is completely independent of each other. The rocking body can rock by nature, but it could not rock continuously before. Now, because of the "indirect intermittent intelligent harmonic technology driving mechanism", the rocking chair can rock freely and continuously. Power off state: The rocking actuator (13) is in the power off self-retracting state (the driving arm is in a straight state pointing backward); standby state: After power is applied, the rocking actuator (13) is in the power-on standby state (the driving arm (13134) is still in a straight state pointing backward under the control of the system, but is always ready to focus on the start time point); start: When the system captures the start point (T01), it commands the rocking actuator (13) to start, and the driving arm (13134) rotates harmonicly according to the preset speed in accordance with the rocking wave phase of the rocking body. Working principle of the oscillating actuator: Special note: The system's built-in mechanism is as follows: The oscillating body and the actuator are two independent moving bodies, each with its own rotational speed and angular velocity. The actuator does not move the oscillating body; rather, when the oscillating body's rotational angular velocity is lower than the actuator's, the actuator briefly pushes the oscillating body due to the angular velocity difference, accelerating it. The pushed oscillating body, due to its increased speed, exceeds the actuator's angular velocity and rolls freely forward at the new speed. The drive arm also moves according to its set speed and motion. However, when the oscillating body's oscillation angular velocity is faster than the drive arm's rotational angular velocity, there is no indirect interaction between the oscillating body and the drive arm. The drive arm has no influence on the oscillating body; instead, they each move independently according to their own angular velocities. There is also another need... Key points of analysis: Due to the built-in mechanism of the rocking chair, it is an unstable device. Even a slight breeze will cause it to rock. In other words, the rocking chair has its own rocking property. No special activation procedure is required; the mere act of sitting down is enough to make it rock. The rocking actuator is not designed to start the rocking chair. It is merely an "assistor" that can only respond to the rocking wave (harmonics) of the rocking body to assist in the rocking. When the rocking chair is stationary or below the minimum rocking speed, the activation of the rocking actuator is ineffective. Only when the rocking body's angular velocity is higher than the minimum angular velocity can the rocking actuator be activated (intervening during the rocking). It can then intervene at the opportune moment, like a jumper in a rope skipping game, moving in harmony with the harmonics. This intervention point is the starting point (T01), and this wave is the rhythm of the rocking. Stopped state: The swing drive can be stopped at any time. After stopping, the drive arm will automatically retract to the straight rear position. Another situation is that the swing will automatically stop after reaching the preset time end and automatically retract to the stopped state.

[0118] The rocking actuator (13) handles human movement or abnormal situations: The rocking actuator has an intelligent processing mechanism. When human movement causes rocking chair movement, the system cannot capture the starting point (T01) normally, and the actuator will be in an unresponsive state before receiving the command. After receiving the command, the actuator will also determine whether the angular velocity of the rocking body meets the preset conditions before it will take action to start the drive. After starting the drive, there is also an automatic mechanism to harmonize the speeds of the two. Therefore, the rocking actuator will automatically and intelligently handle these abnormal situations when the rocking body is in an abnormal state.

[0119] like Figure 5a This is a diagram showing the installation location of the indirect intermittent intelligent harmonic technology oscillator (13) in this embodiment. The oscillator (13) in this embodiment is installed between the rear end of the oscillator (1) and the ground. The drive arm (13134), which is an indirect power actuator (13131), is set to rotate back and forth within an angle range of less than 90° between the rear end of the oscillator (1) and the ground to intermittently drive the oscillating body. This arrangement is specially designed based on harmonic control technology to indirectly utilize the ground reaction force in order to protect the free oscillation nature of the oscillating body.

[0120] like Figure 5c The diagram shows the phase of the oscillation wave of the harmonic technology control system (132) of the indirect harmonic technology driver (13) in this embodiment, and a schematic diagram of the harmonic drive start time T01.

[0121] The indirect harmonic technology compensator (131) also has the characteristic of single-sided speed difference energy transmission. That is, the kinetic energy output by the compensator is driven by the swaying wave of the swaying body and is superimposed with the swaying potential energy of the swaying body. Only when the swaying angular velocity of the swaying body is lower than the preset gear speed (because the rotational angular velocity of the drive arm is the preset speed of pushing the swaying), the indirect kinetic energy of the drive arm can promote the swaying body. When the swaying angular velocity of the swaying body reaches or exceeds the angular velocity of the drive arm, the boosting effect naturally disappears, thereby achieving the harmonic swaying effect of "going with the flow".

[0122] It should be noted that this embodiment utilizes ground reaction force for indirect energy compensation. Other embodiments may also employ indirect energy compensation methods such as inertial force from space energy blocks or indirect energy compensation from space magnetic field energy. However, regardless of the indirect energy compensation method used, the electronic control system can only utilize harmonic control technology, which is the only intelligent control approach to solve the dynamic compensation of a circular swaying body. Other examples of indirect kinetic energy compensation obtained by those skilled in the art without creative effort are all within the scope of protection of this invention. Embodiment 3: Reclining Cabin Embodiment: As shown in the figure below. Figure 6As shown, the reclining cabin (2) is installed on the upper part of the rocking frame (1) by welding four structural components (14) to the front and rear of the rocking frame, including: backrest mechanism (21), seat plate (22) and leg support mechanism (23).

[0123] The backrest mechanism (21) is shown in Figure 7, including: backrest body (211), backrest bracket (212), and backrest lifter (T213). The backrest mechanism is set to be able to make a stepless tilt of 72° relative to the seat plate with the rear structural member (14) as the axis, so as to adjust the upper body posture angle of the passenger, and also take into account the adjustment of the swaying center of gravity and swaying performance of the swaying body.

[0124] Backrest body (211) such as Figure 7a As an independent pluggable modular design, it has a plug-in slot at the bottom for easy disassembly and assembly, which facilitates the insertion of the backrest bracket (212) into the pin, so as to realize the quick disassembly and assembly of the backrest, easy plugging and unplugging, and anti-accidental release locking.

[0125] The lower end of the backrest bracket (212) has a suspension hole, which is connected to the movable screw of the rear end structure (14) of the rocker frame (1). The upper end is rotatably connected to both ends of the hexagonal drive shaft (T12) of the backrest lifter (T213) and locked by a retaining ring.

[0126] Backrest lift (T213) Figure 9d The elevator is supported on the frame (11) of the swing frame (1) by a square support tube (T15) and live connecting pins (T16) at both ends, allowing the elevator to rotate slightly relative to the swing frame (1).

[0127] Seat plate (22) as Figure 8 The seat plate is made of wire mesh and is designed with an ergonomic streamline shape, with a higher front and lower back configuration. It has four notches at its corners for fastening and connecting with four structural members (14) on the front, back, left, and right sides. The four structural members (14) on the frame (11) are detachably mounted in the middle of the rocking frame (1). The rear end is hinged to the backrest mechanism (211) via the rear structural member (14); the front end is hinged to the leg support mechanism (213) via the front structural member (14). To accommodate the rocking motion, the front-to-back drop of the seat plate is limited to 50mm-115mm to conform to the curve of the human buttocks and ensure that the rider does not experience slippage or friction discomfort during continuous rocking motion. In this embodiment, the front-to-back drop of the seat plate is set to 80mm.

[0128] Example 4: Leg support mechanism (23) Example:

[0129] like Figure 9As shown, the leg support mechanism (23) is used to support and adjust the leg posture of the passenger. It includes: a leg rest (231), a foot rest (232), and an extension mechanism (233); the extension mechanism (233) further includes a lifter (T2331) (T is a general part code), a variable triangle (2332), and an irregular quadrilateral (2333); the leg rest (231) and the foot rest (232) are located on the upper part of the extension mechanism (233) and extend or retract as the extension mechanism (233) is driven.

[0130] The extension mechanism (233) adopts a dual-stage linkage composite extension structure designed based on the product efficiency principle of "variable triangle (2332) + unequal-sided quadrilateral (2333)" to solve the dilemma of the lower limbs being limited by the space in which they extend and retract.

[0131] Leg lift (T2331) Figure 9d It adopts a lifting device assembly that is compatible with the backrest lifting device (T213). This assembly includes a lifting motor (T11), a hexagonal drive shaft (T12), a lifting screw (T13), a lifting screw reversing head (T14), a square support tube (T15), a connecting pin (T16), a lifting screw nut seat (T17), a lifting screw limit switch (T18), and a limit retaining ring (T19).

[0132] During lifting and lowering, such as Figure 9d Combination Figure 9e After receiving the lifting signal (taking lifting as an example): the lifting motor (T11) rotates the reversing bevel gear of the lifting screw reversing head (T14) through the hexagonal transmission shaft (T12), causing the rotational power to be reversed by 90° and transmitted to the lifting screw (T13); the lower end of the lifting screw is provided with a lifting screw nut seat (T17), which is fixed to the top of the square support tube (T15), and the two ends of the square support tube (T15) are rotatably connected to the supporting device, which serves as the host, by movable connecting pins (T16). Therefore, when the lifting screw (T13) rotates with the lifting screw nut seat (T17), it will be pushed upwards. Therefore, the leg rest (231), which is movably connected to the same shaft, will rise through the hexagonal drive shaft (T12); since one pivot point of the footrest (232) is connected to the leg rest (231), and the other pivot point is connected to the linkage rod (23332) of the scalene quadrilateral (2333), and the linkage arm of the scalene quadrilateral is hinged to the hexagonal drive shaft (T12), the leg rest (231) and the scalene quadrilateral (2333) together extend and lift the footrest (232) to a predetermined height angle and position, as shown. Figure 9eThis allows the leg rest (231) to reach the preset height angle and spatial position, and also lifts the feet to a level higher than the heart. In this embodiment, the preset length of the leg rest (231) is 430mm, the preset length of the footrest (232) is 240mm, the length of the extended support mechanism is 670mm, and the tilt angle and rotation extension angle are 108-118°. It also has the function of adjusting the relative position of the occupant's leg center of gravity G2 and the system center of gravity Go, so as to adjust the swaying performance and reclining comfort of the seat in real time.

[0133] The leg support mechanism in this embodiment has an extension endpoint designed to raise the user's feet significantly above heart level. This allows blood in the lower limbs to flow back to the heart more quickly due to gravity, effectively promoting blood circulation, relieving leg fatigue, and providing health benefits. This height can be adjusted steplessly within a wide range, depending on the user's comfort.

[0134] Example 5: Xiaoyao Engineering Desk (3):

[0135] like Figure 12 As shown, the ergonomic desk (3) is used to provide a platform for work, study, or entertainment. The ergonomic desk (3) is placed on the round sleeve of the front structural member (14) of the rocking frame (1) by fastening the round notches on the supporting feet. In order to keep the desk stable in rocking, it is also provided with anchor hooks (340) and anchor hook length adjusters (341). Users can adjust the locking force of the anchor hooks to make the desk easy to remove, place, fix, and fine-tune its position, so as to meet the needs of different heights and usage scenarios.

[0136] Example 6: The self-oscillating mechanism of human chair potential energy harmonics

[0137] like Figure 13 , Figure 13a As shown, the human-chair potential energy harmonic self-swaying mechanism is a human-chair collaborative swaying mechanism specially constructed by this reclining chair. In the context of this invention, harmonics are commonly known as momentum, a technology that moves with the potential energy of the swaying wave; the mechanism is a mechanism that enables the rocking chair to sway by deeply coupling multi-dimensional non-obvious technological elements in the swaying performance of the rocking body. The relevant elements have been analyzed before, mainly including the structural hole layout position parameters of the skeleton (11), the preset curvature radius of the arc rocking foot (12), and the multi-stage adjustment parameters of the reclining cabin (2), such as: the tilt angle adjustment parameters of the backrest, the tilt parameters of the seat board, the leg support parameters, and the distribution parameters of the center of gravity at both ends of the occupant's body, etc. By scientifically configuring these parameters, the damping coefficient of the system approaches 0, and then the intelligent energy body of the "human body" is integrated for readjustment and intelligent participation, constructing a human-chair energy collaborative self-swaying body that does not require energy.

[0138] The involvement of the "human body" in the swaying process is not a direct, coordinated effort, but rather an indirect, harmonic response driven by an inherent scientific mechanism that subtly influences the swaying, making the human consciously or unconsciously participate. A physical phenomenon helps illustrate this: when a flexible body moves alongside a rigid body, their movements are not perfectly synchronized; a "potential energy phase difference" exists. This phase difference, depending on the different harmonic states at different swaying frequencies, produces… To illustrate the different effects, consider two examples from different scenarios to help understand the principle of "harmonics": In some earthquake-prone countries and regions, swimming pools are built on the rooftops of high-rise buildings. The water in the pool interferes with and attenuates seismic waves during earthquakes, reducing building sway. The principle is based on the "potential energy phase difference" between the water's sway and the building's sway. However, this "interference suppression and attenuation" mechanism doesn't utilize "harmonics," but rather the interference characteristics of "disharmonics." The irregular waves of the earthquake interfere with the swaying waves of the water, thus canceling out and suppressing the building's sway. The conclusion is that "disharmonics" generate interference.

[0139] Why does the human body, when swaying with the rocking chair, a specially designed rocking body, contribute to the rocking effect? ​​The secret lies in the fact that the human body is an intelligent and dynamic entity, consciously or unconsciously moving in harmony with the rocking waves of the rocking chair, a phenomenon that can be simply understood as "harmonic resonance." The conclusion is that harmonics can produce resonance, and the energy after resonance is increasing. Therefore, when a passenger rides on the rocking chair, because the human body is a flexible body while the rocking chair is a rigid body, there is a "potential energy phase difference" between their movements. Figure 13a Furthermore, since the human body is an "intelligent, dynamic energy body," meaning that the human body "moves in harmony with the swaying waves," thus amplifying the swaying waves, the human body not only does not interfere with the potential energy of the swaying body, but also intentionally or unintentionally moves in accordance with the swaying waves. Therefore, a mutually reinforcing effect of "the chair carrying the person swaying, and the person assisting the chair in swaying" is formed during the swaying. In this way, the human body actually acts as an "energy expansion and storage body" during the swaying. Thus, the human body intentionally or unintentionally plays a role in "indulging" and "developing" potential energy. This "indulgence" and "development" will subtly affect the expansion and contraction of the swaying potential energy, promoting and amplifying the expansion and storage of the swaying potential energy of the swaying body.

[0140] The most valuable aspect of this reclining chair is that its "harmonic oscillation drive mechanism" and "human-chair potential energy harmonic self-oscillation mechanism" function like a micro-Tai Chi energy body. The "human-chair harmonic self-oscillation mechanism" has the performance characteristics of relieving fatigue, recharging energy, stimulating vitality, and boosting spirit, enabling the human body to obtain activated energy. On the other hand, the "harmonic oscillation drive mechanism" has the performance characteristics of relaxing muscles, weakening thoughts, alleviating lethargy, softening the body, and promoting the human body to quickly enter deep sleep to replenish energy, thus enabling the human body to quickly restore physical strength. The two are yin and yang, coexisting in harmony and cooperating, with their functions complementing each other, forming a perfect combination, allowing the human body's energy to be naturally circulated, renewed, and replenished. This is the most valuable aspect of this reclining chair.

[0141] Example 7: Illustration of the multi-functional and multi-dimensional beneficial effects of this reclining chair:

[0142] like Figure 10a , Figure 10b As shown, this invention can be applied in various ways in practice.

[0143] in Figure 10a It shows the work posture. Figure 10b It showcases a state of rest and recuperation:

[0144] Figure 10A shows the rocking motion of this recliner;

[0145] Figure 10B shows the reclining chair in a seated working position.

[0146] Figure 10C shows the reclining chair in a working position with legs crossed.

[0147] Figure 10D shows the reclining chair in a working position with legs hanging down.

[0148] Figure 10E shows the reclining chair in a semi-reclining position with legs crossed, comfortably reading information on a mobile phone.

[0149] Figure 10F shows the reclining working position of this chair (can be operated by voice) (can close eyes and rest at any time).

[0150] Figure 10G shows the reclining and sleeping posture of this reclining chair;

[0151] Figure 10H shows the reclining and resting posture of this reclining chair;

[0152] Figure 10i shows the semi-reclining posture of this reclining chair for a brief period of relaxation;

[0153] Figure 10J shows the sitting posture of this reclining chair, a meditative and resting posture;

[0154] Figure 10K shows the balanced sitting posture of this reclining chair for quiet contemplation (visual objects that guide the mind can be placed in front of the chair).

[0155] Figure 10L shows the automatic welcoming and welcoming posture of this recliner for passengers;

[0156] The above-described embodiments are only partial examples of posture diagrams. All postures of this reclining chair can be adjusted arbitrarily according to mood and comfort, and any adjustment in one place will affect the overall posture changes.

[0157] Example 8: The working process of this reclining chair: as follows Figure 14 This reclining chair is itself an unstable energy system with a damping coefficient approaching zero. Without special activation, it enters a swaying state simply by the user sitting down, naturally operating within the chair's potential energy harmonic self-swaying mechanism. This continuous self-swaying state is the chair's default swaying mode, suitable for most scenarios and times. Due to its precisely structured potential energy harmonic self-swaying mechanism, the chair will sway freely and continuously as long as the user doesn't intentionally move against the potential energy. If the user is somewhat aware of "going with the flow" and occasionally moves slightly in accordance with the flow, it can stimulate the chair to sway significantly. This "high mood" in the chair simultaneously provides the user with more pleasant "emotional value" and "biovitality," thus naturally creating a mutually beneficial, mutually stimulating, and comfortable sitting effect between the person and the chair. So, what would happen if someone occasionally moves against the potential energy? There are no harmful consequences. On the contrary, the user can utilize the "anti-potential energy" property to instantly stop the chair in a certain sitting position. For example, when needing to get up immediately, the user can use the "anti-potential energy" property to abruptly stop in the sitting position, faster than the system's steady support, to quickly sit up or get up. The system's rocking actuator is mainly used when the user needs to take a nap. In this case, simply say "Little Bao, Little Bao, I want to sleep" or press the "Relax" button on the remote control, and the rocking chair will enter the "intelligent harmonic drive mode." Close your eyes, relax your mind and body, and enjoy a peaceful sleep. The chair will naturally stop rocking after a default 20 minutes. If you are still not asleep, repeat the above steps to continue rocking for another 20 minutes. There are other situations where the actuator is needed, such as when infants or elderly people without self-care abilities need rocking. In these cases, the actuator can be activated to assist in rocking.

[0158] The reclining chair of this invention is not a basic reclining chair, but a high-end seat with both form and function, possessing advanced health and deep comfort features. Its structure is only its "form", while the profound functions contained in the "form" are its "spirit".

[0159] The core technology of this invention is the successful development and application of harmonic oscillation technology. "Without harmonic technology, there would be no realization of the free and continuous oscillation function of the rocking chair." It has fundamentally changed the oscillation mode of the arc-shaped rocking chair and fundamentally solved the world problem that the arc-shaped rocking chair cannot oscillate continuously.
