Description

Technical Field

[0001] This invention relates to the field of intelligent seating technology, and more specifically, to an intelligent electric sofa chair with zero wall resistance and zero gravity based on human body perception. Background Technology

[0002] In modern society, people's lifestyles and scenarios are becoming increasingly diverse. The demand for seating products has long surpassed the basic function of simply "sitting," and has shifted to a comprehensive experience that is comfortable, adaptable, intelligent, and safe. Whether it's relaxing at home, taking a break during office work, or recovering from exercise or undergoing rehabilitation, chairs have become essential tools used frequently in daily life. However, existing sofa and chair products have many limitations in design and function that urgently need to be addressed, making it difficult to meet the core needs of different groups of people in different scenarios.

[0003] From a usage perspective, traditional sofas and chairs often need to be placed against a wall, which not only limits the flexible layout of interior spaces but also makes placement a challenge in small apartments, open-plan offices, and other spaces with limited room, preventing the full utilization of space. Furthermore, the support structures of existing products are mostly fixed designs, making it difficult to dynamically adjust parameters such as height and angle according to the user's posture. Different users have different heights and body types, and even the same user has vastly different needs for support points depending on their posture—sitting, leaning, or relaxing. Fixed support structures cannot accurately match these dynamically changing needs, leading to uneven stress on the body. Key areas such as the waist, shoulders, and back do not receive effective support or receive excessive support. Over time, this can easily cause muscle fatigue and stiffness, and may even lead to sports injuries such as lower back muscle strain and shoulder joint wear. In severe cases, it can even induce chronic diseases such as lumbar disc herniation and cervical spondylosis.

[0004] In terms of intelligent adaptation and safety protection, existing sofas and chairs lack the ability to sense human posture and cannot promptly identify whether a user's posture is unbalanced or poses a potential risk of injury. For example, when a user is engaging in light activity or relaxing on the sofa, if their body tilts excessively, existing products cannot provide effective warnings or assistance in adjustment, which may lead to accidental tipping or excessive pressure on certain parts of the body. In addition, the moving parts of traditional sofas and chairs are mostly exposed, and dust and moisture easily accumulate in the gaps, which not only affects the product's lifespan but may also pose safety hazards to users, especially when there are elderly people or children in the home, posing a risk of being pinched or bumped. The lack of comprehensive consideration of comfort, durability, and safety reduces the user experience.

[0005] These problems highlight the significant shortcomings of existing sofas and chairs in meeting people's growing demands for a high-quality lifestyle. There is an urgent need for a smart electric sofa and chair that can be placed without leaning against a wall, possesses human body sensing capabilities, dynamically adjusts its support posture, and combines safety and comfort to overcome the deficiencies of current technology.

[0008] According to one embodiment of the present invention, a membrane is fixedly covered on the upper surface of the base, and the docking groove is fixedly connected to the highest arc surface of the membrane.

[0009] According to one embodiment of the present invention, a second component is further included; the second component includes a docking rod inserted into the docking groove, a support member being rotatably connected to the top end of the docking rod, and transverse plates being symmetrically fixedly connected to the body of the docking rod; a sliding column is fixedly connected to the transverse plate, and a magnet is fixedly connected to the bottom end of the sliding column.

The fixed end of the spring away from the inner wall of the cylindrical shell is fixedly connected to a magnet; a Hall switch is embedded in the top wall of the inner cavity of the cylindrical shell.

[0011] According to one embodiment of the present invention, the support member has an air pump placement chamber, and the support member has symmetrically formed inner grooves, each of which is fixedly connected to a strip chamber, and a pusher is slidably connected to the strip chamber.

[0012] According to one embodiment of the present invention, an auxiliary through hole with a diameter larger than the output diameter of the drive motor B is provided at the bottom end of the main frame away from the drive motor A.

[0014] According to one embodiment of the present invention, a bidirectional air pump is installed in the air pump placement chamber.

[0015] According to one embodiment of the present invention, the bar bin and the pusher are arranged as a group, and a total of four groups are provided.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This human-sensing-based, zero-wall, zero-gravity smart electric sofa chair achieves a deep integration of intelligent sensing and dynamic adaptation, significantly improving comfort and adaptability. Through a posture sensing unit composed of Hall switches and magnets, the sofa chair can capture real-time changes in the user's body posture. Combined with the coordinated drive of drive motor A, drive motor B, and a bidirectional air pump, it achieves precise adjustments to the longitudinal and lateral angles, as well as auxiliary support in case of imbalance. This dynamic adjustment capability allows the sofa chair to adapt to the different heights and body types of users, while simultaneously meeting the support needs of the same user in different postures such as sitting, leaning, and relaxing. It ensures that all key parts of the body receive uniform and effective support, fundamentally solving the problems of fixed support and poor adaptability of traditional sofa chairs, making the user experience more personalized and comfortable.

[0018] 2. This human-sensory-based zero-wall, zero-gravity smart electric sofa chair significantly expands its application scenarios through its improved zero-wall design and spatial adaptability. By utilizing the sliding connection between the sliding plate and the base, along with the structural design of each drive component, the sofa chair can achieve zero-gravity posture adjustment without relying on a wall, breaking the limitations of traditional sofa chairs on placement. Whether in small apartments, open-plan offices, hotel rooms, or rehabilitation centers, it can be flexibly placed to fully utilize limited space and enhance spatial layout flexibility. Simultaneously, the zero-wall design allows the sofa chair to extend forward and backward without obstruction from walls, providing users with more ample relaxation space and further enhancing the comfort of the zero-gravity experience.

[0019] 3. In this human-sensing, zero-wall, zero-gravity smart electric sofa chair, the membrane not only seals and protects moving parts, extending the product's lifespan, but also provides effective cushioning, preventing injuries from accidental contact with moving components. The posture imbalance warning and auxiliary adjustment functions can promptly detect and intervene in dangerous postures, helping users adjust to a safe and comfortable position. This reduces the risk of sports injuries such as muscle strains and joint wear caused by improper posture, making it particularly suitable for post-exercise recovery, rehabilitation care, and the elderly—groups with high requirements for support and safety—making the use process safer and more reliable.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] This invention provides a zero-wall, zero-gravity intelligent electric sofa chair based on human body perception. See [link to relevant documentation]. Figures 1-3 The structure includes a seat 1, a base 2, and a sliding plate 3. The sliding plate 3 is slidably connected to the side wall of the base 2. The base 2 has an internal cavity and also includes a first component 4. The first component 4 includes a frame plate 401 symmetrically fixedly connected to the upper surface of the base 2. A drive motor A402 is fixedly connected to the upper surface of the base 2, and a main frame 403 is fixedly connected to the output shaft of the drive motor A402. A drive motor B404 is fixedly connected to the upper surface of the base 2, and a screw 405 is fixedly connected to the output shaft of the drive motor B404. The drive motors A402 and B404 are symmetrically distributed on the upper surface of the base 2. The base 2 has an internal cavity to accommodate some transmission components and wiring. The function of the sliding plate 3 is to cooperate with the zero-wall design. When the sofa chair adjusts its posture, the sliding plate 3 can slide along the side wall of the base 2, allowing the seat 1 to extend backward without relying on the wall, meeting the requirements of the zero-gravity posture, and improving space utilization.

[0036] See Figures 4-6 As shown, the first component 4 provides multi-angle body support for the user; the drive motor A402 can indirectly drive the docking groove 409 to adjust its longitudinal angle, i.e., the direction perpendicular to its output shaft, through the main frame 403; the bottom of the main frame 403, away from the drive motor A402, has an auxiliary through hole with a diameter larger than the output diameter of the drive motor B404. Driven by the drive motor A402, the main frame 403 drives the docking groove 409 to adjust its longitudinal angle, i.e., the angle change perpendicular to the output shaft of the drive motor A402, to adapt to the user's leaning posture.

[0037] The screw 405 is used to adjust the lateral angle of the docking groove 409 in conjunction with the gear 407; that is, in the direction parallel to the output shaft of the drive motor B404. When the drive motor B404 drives the screw 405 to rotate, the gear 407 rotates accordingly, thereby driving the shaft 406 to rotate.

[0038] The membrane 410 is used to enclose the components, reducing dust and moisture in the gaps between moving parts and providing passive safety protection for the user. The membrane 410 effectively prevents dust, moisture, and other impurities from entering the gaps between components, extending the product's lifespan. Simultaneously, it forms a buffer between the user and the moving parts, preventing accidental bumps or pinching injuries and improving user safety.

[0039] According to one embodiment of the present invention, a shaft 406 is rotatably connected to the middle of the main frame 403, a gear 407 is fixedly connected to the middle of the shaft 406, and N-shaped parts 408 are fixedly connected to both ends of the shaft 406. A docking groove 409 is fixedly connected to the top surface of the N-shaped parts 408. The N-shaped parts 408 are integrally formed of aluminum alloy, making the structure lightweight and stable. The docking groove 409 is made of engineering plastic, possessing good toughness and wear resistance. It has an internal groove that matches the embedded block of the docking rod 501, which is used to achieve a stable connection between the first component 4 and the second component 5, ensuring the accuracy of power transmission during angle adjustment.

[0040] According to one embodiment of the present invention, a membrane 410 is fixedly covered on the upper surface of the base 2, and the docking groove 409 is fixedly connected to the highest arc surface of the membrane 410.

[0041] According to one embodiment of the present invention, see Figure 7 and Figure 8 As shown, it also includes a second component 5; the second component 5 includes a docking rod 501 inserted into the docking groove 409, a support member 502 rotatably connected to the top of the docking rod 501, and a transverse plate 503 symmetrically fixedly connected to the body of the docking rod 501; a sliding column 504 is fixedly connected to the transverse plate 503, and a magnet 505 is fixedly connected to the bottom of the sliding column 504. The seat 1 is adapted to the support member 502 in the second component 5, providing the user with a direct sitting and back support surface. Its size design takes into account the needs of users of different body types, ensuring comprehensive support range. The second component 5 is mainly responsible for human posture perception, imbalance warning, and auxiliary support adjustment; the magnet 505 uses a high-performance permanent magnet with stable magnetism; the support member 502 is made of high-strength engineering plastic and sponge composite, and the surface is covered with breathable fabric, which not only ensures structural strength but also has good comfort. Its function is to directly support the seat 1 and achieve posture adjustment with the cooperation of various components.

[0042] According to one embodiment of the present invention, a cylindrical shell 506 is symmetrically hinged to the bottom surface of the support member 502. A spring 5041 is fixedly connected inside the cylindrical shell 506. The spring 5041 has good elastic recovery performance. The end of the spring 5041 away from the inner wall of the cylindrical shell 506 is fixedly connected to a magnet 505. A Hall switch 507 is embedded in the top wall of the inner cavity of the cylindrical shell 506. The Hall switch 507 has the characteristics of high sensitivity and fast response. It is used in conjunction with the magnet 505 to form an attitude sensing unit. When the support member 502 tilts, it will drive the cylindrical shell 506 to move synchronously, causing the distance between the Hall switch 507 and the magnet 505 to change, thereby triggering signal transmission.

[0043] According to one embodiment of the present invention, an air pump placement chamber 508 is provided inside the support member 502, and symmetrical inner grooves are provided on the support member 502. Each inner groove is fixedly connected to a strip chamber 509, and a pusher member 510 is slidably connected inside the strip chamber 509. The air pump placement chamber 508 adopts a sealed design and is equipped with a bidirectional air pump. The bidirectional air pump has bidirectional functions of inflation and deflation, low operating noise, and high efficiency, and is used to provide power for auxiliary support adjustment. A filter screen is installed on the outside of the air pump placement chamber 508 to ensure the operation of the bidirectional air pump inside. At the same time, the connecting pipes connecting the bidirectional air pump and each strip chamber 509 are all routed inside the support member 502 to avoid exposed wiring and improve structural neatness and safety.

[0044] The bidirectional air pump in the air pump placement compartment 508 and the connecting pipe of the strip compartment 509 both run from inside the support member 502. The strip compartment 509 and the pusher member 510 are a group, and a total of four groups are provided. The strip compartment 509 is made of lightweight aluminum alloy and has a hollow internal structure. It is connected to the bidirectional air pump through the connecting pipe. Its function is to provide a sliding track and gas-containing space for the pusher member 510. The pusher member 510 is made of soft rubber and hard plastic composite, which has a certain degree of support and flexibility. The strip compartment 509 and the pusher member 510 are a group, and a total of four groups are provided, each corresponding to a different position of the support member 502. Driven by the bidirectional air pump, they can extend in the direction of support required to provide targeted auxiliary support for the user.

[0045] According to one embodiment of the present invention, an auxiliary through hole with a diameter larger than the output end diameter of the drive motor B404 is provided at the bottom end of the main frame 403 away from the drive motor A402. The larger diameter of the auxiliary through hole at the bottom end of the main frame 403 away from the drive motor A402 provides space for the installation and movement of the output shaft of the drive motor B404 and the screw 405, thus preventing interference between components.

[0046] According to one embodiment of the present invention, the connecting rod 501 consists of an inner block and a rod body. The inner block is adapted to the slot of the connecting groove 409. The connecting rod 501 is made of engineering plastic and the rod body is made of aluminum alloy. The inner block is adapted to the slot of the connecting groove 409 to ensure a stable connection between the connecting rod 501 and the connecting groove 409. At the same time, the connecting rod 501 can be selected with different heights according to the user's height, body type, and other needs, improving the adaptability of the product.

[0047] The working principle of this device is as follows:

[0048] In its initial state, the sofa chair can be placed anywhere in the room without relying on a wall. The sliding plate 3 and the side wall of the base 2 remain relatively stationary, and all components are in their initial positions. When a user approaches and sits on the seat 1, the seat 1 transmits pressure to the support member 502. The support member 502 maintains its initial posture after receiving the force. At this time, the Hall switch 507 and the magnet 505 are in their initial relative positions and no signal is triggered. When the user adjusts their body posture, such as leaning back or tilting to the side, the support member 502 will change its angle accordingly, thereby causing the cylindrical shell 506 hinged at its bottom to move synchronously. The movement of the cylindrical shell 506 changes the distance between the Hall switch 507 embedded in the top wall of its inner cavity and the magnet 505 at the bottom of the sliding column 504. After sensing the change in magnetic field, the Hall switch 507 quickly generates an electrical signal and transmits it to the device's main controller.

[0049] After receiving the signal, the main controller activates the corresponding drive components to make adjustments based on the direction and degree of posture change indicated by the signal feedback. If the user needs to adjust the longitudinal angle, i.e., change the angle of leaning forward or backward, the main controller will control the drive motor A402 to start. The output shaft of the drive motor A402 drives the main frame 403 to rotate around the output shaft. The rotation of the main frame 403 is transmitted to the docking groove 409 through the shaft 406 and the N-shaped part 408. The docking groove 409 then drives the support part 502 connected by the docking rod 501 to adjust the longitudinal angle of the seat 1 until it reaches an angle that adapts to the user's posture, achieving a zero-gravity leaning state and reducing body pressure.

[0050] When the user needs to adjust the lateral angle, i.e., the support angle in the left and right directions, or when the main controller determines that lateral support adjustment is needed based on posture sensing signals, it will control the drive motor B404 to start. The output shaft of the drive motor B404 drives the screw 405 to rotate. The screw 405, through meshing with the gear 407, drives the shaft 406 to rotate in the middle of the main frame 403. The N-shaped parts 408 at both ends of the shaft 406 rotate accordingly, thereby driving the docking groove 409 and the support member 502 to adjust the lateral angle, ensuring that the support direction of the seat 1 is accurately matched with the user's body posture. During this process, the auxiliary through hole at the bottom of the main frame 403 provides sufficient movement space for the screw 405 and the output shaft of the drive motor B404, avoiding interference between components and ensuring the smoothness of the adjustment process.

[0051] When the relative position change between Hall switch 507 and magnet 505 reaches a preset threshold, the main controller determines that the user's posture is at risk of imbalance. It immediately activates the bidirectional air pump and controls it to inflate the strip compartment 509 on the support 502 corresponding to the direction of imbalance. Once the air enters the strip compartment 509, it pushes the pusher 510 to slide along the compartment 509 and extend outwards, gently pushing and supporting the user's body to help adjust their posture. Simultaneously, a slight warning signal is emitted through a preset prompting device to remind the user to pay attention to posture safety. If the user adjusts their posture to a safe range, Hall switch 507 and magnet 505 return to their initial relative positions, the main controller controls the bidirectional air pump to release the air, and the pusher 510 returns to its initial position after the air is expelled.

[0052] Throughout the adjustment process, the membrane 410 continuously envelops the moving parts of the first component 4, expanding and contracting with the angle changes of the docking groove 409. This effectively prevents dust and moisture from entering the gaps between components, while providing passive protection for the user to avoid accidental contact with the moving parts during adjustment, preventing bumps or pinches. The sliding plate 3 slides along the side wall of the base 2 according to the extension range of the seat 1, ensuring that the sofa chair does not need to rely on the wall when achieving a zero-gravity posture, making full use of indoor space and improving the flexibility of use. The filter screen in the air pump placement chamber 508 continuously filters the air entering the air pump, ensuring the stable operation of the bidirectional air pump, while the internal wiring connecting pipe avoids wire tangling or exposure, further improving the safety and durability of the product.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
