Description

Technical Field

[0001] This invention relates to intelligent ergonomic chairs, and more particularly to a dynamic chair that can actively adjust sitting posture and exercise the pelvic and / or lower back muscles. Background Technology

[0002] Chairs are a common item in work and daily life. Most people in office jobs spend a significant amount of time in chairs every day. Currently, numerous scientific studies have shown that prolonged sitting has adverse effects on health, particularly on the lumbar spine, cervical spine, back, and pelvis. This is because during periods of high concentration, people tend to maintain the same posture for extended periods without moving or adjusting.

[0003] Existing technologies include dynamic chairs, such as those disclosed in patent documents WO9916335, JP200552317, and WO2019143555. These dynamic chairs allow users to adjust their posture without leaving the seat, thus avoiding prolonged periods of sitting in the same position. This helps mitigate the adverse effects of prolonged sitting. However, these dynamic chairs essentially achieve their dynamic function through an unstable seat structure, requiring the user to actively adjust their center of gravity to change posture; for example, tilting the user to the left will cause the seat to tilt to the left. This dynamic solution does not provide a good user experience, and may even be worse than traditional chairs. This is because users often maintain the same posture for extended periods while focused on work, forgetting to actively move, or any unintentional or subconscious shift in their center of gravity can cause the seat to tilt, resulting in the user being unexpectedly changed in posture and creating the illusion that the chair might tip over. Therefore, these dynamic solutions do not allow users to fully immerse themselves in their work as they would with a traditional chair. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a dynamic chair. This dynamic chair can actively adjust the movement of the seat plate and drive the user's movement through the movement of the seat plate, preventing the user from maintaining the same posture for a long time. At the same time, the adjustment process of this dynamic chair is not sensitive to the user's center of gravity position, thus allowing the user to fully immerse themselves in work as if using a traditional chair.

[0005] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0006] A dynamic seat includes a seat body and a support column. The seat body includes at least a seat board and may also include conventional components such as a backrest and armrests. However, it should be noted that the backrest and armrests are not essential in the technical solution of this invention. The seat described in this invention may also be a stool-like form that only includes a seat board and a support column. For ease of description, these are collectively referred to as seats in this invention.

[0007] The support column, generally columnar in shape, supports the seat plate. It integrates a motion system capable of bending the support column through partial rotation and controlling the degree and direction of this bending, thereby controlling the degree and direction of the seat plate's tilt.

[0008] The motion seat also includes a sensing system and a control system.

[0009] The sensor control system senses the muscle force distribution on the seat base and adjusts the seat tilt according to the force distribution. The sensing system can also measure forces on the seat plate opposite to the direction of seat plate movement. These forces are essentially the resistance exerted by the human body on the moving seat plate, aiming to bring the seat plate back to a desired position, such as a horizontal position, a position set by the user according to their habits, or a position tilted or rotated to a predetermined position according to a programmed setting. In this invention, this position is referred to as the set position. Optionally, the sensing system is distributed at the bottom of the seat plate, the bottom or sides of the support pillars, the seat armrests, and / or the seat back.

[0010] The control system can control the motion system to make the seat plate execute a predetermined motion pattern, thereby causing the human body to respond accordingly to the motion pattern of the seat plate. When the resistance is sufficient to return the seat plate to the set position, the seat will provide a feedback signal, which can be a vibration signal, a sound signal, or other signal means. The resistance that brings the seat plate back to the set position requires the use of the user's back muscles and pelvic muscles. That is, in the process of resisting the movement of the seat plate, the user will exercise their back muscles and pelvic muscles. Therefore, with the aid of an appropriate control program, the seat plate of the dynamic seat of the present invention can perform various motion patterns such as forward and backward tilting, lateral tilting, and rotation, and accordingly mobilize the user's pelvic muscles and / or lower back muscles to achieve the effect of massaging and stretching the corresponding muscle groups.

[0011] The required resistance, the maximum range of motion of the seat, and the time interval between different movement patterns can be determined by the user's activity patterns detected by the sensor system. An appropriate algorithm is used to select the movement pattern and resistance. The motion seat can also provide exercise activities independent of the seat itself.

[0012] The motion seat of this invention can wirelessly communicate with applications on electronic devices such as mobile phones and computers. These applications can track and transmit sensor data to derive activity patterns, calorie burn, weight, and other health parameters. The applications can record and / or analyze these health parameters, such as comparing parameters from different periods and plotting corresponding parameter curves; these parameters can be shared on social media.

[0013] The support column includes a support ring at the bottom and a motion system mounted on the support ring. The motion system includes a lower rotating ring rotatably connected to the top of the support ring, a middle rotating ring rotatably connected to the top of the lower rotating ring, an upper rotating ring rotatably connected to the top of the middle rotating ring, and a seat plate rotatably connected to the top of the upper rotating ring. The support ring, lower rotating ring, middle rotating ring, upper rotating ring, and seat plate are rotatably connected by bearings with internal bearings.

[0014] In some embodiments, each rotating ring is a tubular structure with a continuous wall surface having a first height and a second height, such that the rotation axis of the lower cross-section of the rotating ring does not coincide with the rotation axis of the upper cross-section; in other embodiments, each rotating ring is composed of a circular ring structure and several supports with different heights evenly spaced circumferentially at the bottom of the circular ring structure, and the output shaft of the motor is connected to the supports to realize the independent and controlled rotation of the rotating ring.

[0015] Preferably, the lower rotating ring can rotate in a controlled manner relative to the support ring; the middle rotating ring can rotate in a controlled manner relative to the lower rotating ring; the upper rotating ring can rotate in a controlled manner relative to the middle rotating ring; and the seat plate can rotate in a controlled manner relative to the upper rotating ring. The controlled rotation is achieved by several independent drive units.

[0016] There is an included angle between the normal axis of the lower rotating ring, middle rotating ring, and upper rotating ring and their bottom connecting surface, which is defined as the cross-sectional included angle in this invention. When the seat plate rotates to an angle α of inclination in a certain plane, the rotation angle of the lower rotating ring relative to the support ring axis is σ1, the rotation angle of the middle rotating ring relative to the normal axis of the lower rotating ring and its connecting surface is σ2, and the rotation angle of the upper rotating ring relative to the normal axis of the middle rotating ring and its connecting surface is σ3. To ensure that the user does not rotate when the seat tilt angle changes, as compensation, the rotation angle of the seat plate relative to the normal axis of the upper rotating ring and its connecting surface is σ4. And σ1, σ2, σ3, and σ4 satisfy the following relationship:

[0017]

[0018] The rotation is shown as a rotation vector. In the Cartesian coordinate system, α, β, and γ are the tilt or torsion angles of the seat plate in different orientation directions, respectively.

[0019] This invention can transmit torque and rotation through conventional meshing gears or gear sets, or through rolling elements with a high coefficient of friction. Preferably, the drive unit comprises a gear ring disposed on each rotating ring, support ring, and seat plate, and a motor assembly that meshes with the gear ring. The motor assembly includes a motor and gears or gear sets. The motor is fixed to the inner wall of the lower rotating ring or support ring of the mating gear ring, or to a separately mounted motor bracket. The outer wall of the gear ring is fixedly connected to the inner wall of each rotating ring, support ring, and seat plate.

[0020] Preferably, the bottom of the lower rotating ring, the middle rotating ring, and the base plate are all provided with protruding drive gear rings, and the top of the middle rotating ring and the bottom of the upper rotating ring are provided with partially meshing connecting gear rings; the drive gear ring is engaged with a gear or gear set driven by a corresponding motor, and thus can rotate actively; the connecting gear rings mesh with each other and are used to transmit rotational power.

[0021] Alternatively, all rotating rings and base plates have protruding drive gear rings at their bottom, and each drive gear ring has a matching motor assembly. The motor at the bottom of the base plate is used solely to perform the rotational movement of the base plate.

[0022] Preferably, the gear or gear set includes a planetary gear set, an internal gear, a bevel gear, or a combination thereof. The output shaft of the motor drives the gear ring connected to it to rotate through the sun gear, internal gear, or bevel gear of the planetary gear set, thereby driving the rotating ring connected to the gear ring to rotate.

[0023] Preferably, the bearing is disposed on top of the support ring and each rotating ring.

[0024] Preferably, the outer diameter of the gear ring is smaller than the outer diameter of the corresponding swivel ring, thereby forming a narrow diameter portion protruding from the bottom cross-section at the bottom of each swivel ring, and the outer wall of the narrow neck is the outer wall of the gear ring.

[0025] Preferably, the outer wall of the gear ring at the bottom of the upper-level rotating ring is interference-fitted with the inner wall of the bearing at the top of the lower-level rotating ring or support ring.

[0026] Preferably, the transmission can be achieved by replacing the gear ring with an elastic element having a certain coefficient of friction, and the elastic element is preferably a rubber ring.

[0027] Preferably, to compensate for non-coaxial misalignment, a universal joint is also provided between at least one motor and the rotating ring. The universal joint can be an assembly structure known in the art.

[0028] Preferably, the sensing system is located between the top of the upper rotating ring and the seat plate; or further, depending on the application scenario of the dynamic seat, the sensing system is also provided in the support ring, the seat armrest and / or the seat back.

[0029] Preferably, the motion seat further includes a power source for supplying electrical energy to the control system, sensing system, and motion system.

[0030] Preferably, the motors in each motor group are stepper motors or servo motors with position feedback signals.

[0031] It should be understood that, in this invention, the controlled rotation of each rotating ring allows the support column to bend within a certain angle range, and the direction of this bending is arbitrary. For example, when the support ring of the support column is placed vertically, by controlling the rotation direction and angle of the upper, middle, and lower rotating rings, the upper end of the support column can bend at any desired angle in any desired direction in the horizontal dimension. This allows the seat plate to be tilted at any desired angle in any desired direction, achieving tilting in any plane. When the seat plate continuously performs the action of tilting to the desired angle in multiple planes, the seat plate can achieve undulating rotation on the horizontal plane.

[0032] The seat tilt angle is four times the tilt angle (θ) formed by the difference between the first and second heights of the swivel ring. For example, a 10-degree swivel tilt angle (θ) allows the seat tilt angle to be between 0 and 40 degrees; in another embodiment, a 90-degree seat tilt angle can be achieved by selecting a 22.5-degree swivel tilt angle (θ). For dynamic seating, a 10-degree swivel tilt angle is considered sufficient and is a practical limitation, but a soft limitation. To provide a good user experience and safety, the upper limit of the seat tilt is preferably 40 degrees. Higher and lower tilt angles can be achieved. Larger angles can be used for specific customers and applications.

[0033] Compared to existing technologies, the advantages of this invention are as follows: Since the rotation of each ring is driven by a motor, the tilt direction and angle of the seat are controlled, meaning the seat posture will not change due to changes in the user's center of gravity. This feature allows users to use the dynamic chair of this invention with peace of mind, without misjudging the possibility of the chair tipping over due to subconscious posture changes. Furthermore, the tilt degree and direction of the seat can be changed at a relatively slow speed through a preset program in the control system, thereby massaging and stretching the user's pelvis and lower back muscles. This slow speed allows the user to adapt to the changes in seat posture consciously or subconsciously without disturbance, thus avoiding maintaining the same posture for extended periods and preventing disturbance caused by changes in seat posture. Of course, the dynamic chair of this invention can also change the tilt degree and direction of the seat at a relatively fast speed when the user is fully prepared, based on their commands, such as commands to increase the speed of seat tilt changes or commands to rotate the tilt direction.

[0034] The dynamic chair of this invention can be applied to ergonomic chairs for office or home use, chair equipment for rehabilitation training, and hardware facilities for games, audio-visual entertainment, or training that simulate real-life scenarios.

[0035] The rotating support system of this invention can be used not only in ergonomic chairs, but also in a variety of suitable applications such as electronic devices, electrical appliances, exhibition stands, and robotic arms. Attached Figure Description

Detailed Implementation

[0050] Example 1

[0051] Referring to Figures 1-5, a dynamic seat is provided, which includes a seat plate (not shown in the figures) and a support column supporting the seat plate; the support column is integrated with a motion system, which can cause the support column to rotate locally, thereby causing the support column to bend in a certain direction and at a certain angle, and thus causing the seat plate to tilt in a certain direction and at a certain angle; the motion system can also cause the seat plate to rotate in a certain direction and at a certain angle.

[0052] The motion seat also includes a control system 10 and a sensing system 12. The sensing system 12 can measure the resistance force exerted by the user on the seat plate in the opposite direction of the seat plate's movement. The control system 10 can control the motion system to make the seat plate perform a predetermined movement pattern, thereby causing the human body to make a corresponding resistance response to the movement pattern of the seat plate. With the aid of appropriate control programs, the seat plate of the motion seat can perform various movement patterns such as forward and backward tilting, lateral tilting, and rotation, and accordingly mobilize the user's pelvic muscles and / or lower back muscles to achieve the effect of massaging and stretching the corresponding muscle groups.

[0053] The motion seat also includes a communication system for wireless communication between the motion seat and electronic devices such as mobile phones and computers. The electronic devices have corresponding applications installed, which can track and transmit sensor data to derive activity patterns, calorie burn, weight, and other health parameters. The applications can also record and / or analyze these health parameters, such as comparing health parameters at different times and plotting corresponding parameter curves; these parameters can be shared on social media.

[0054] As shown in Figures 1-3, the support column includes, from bottom to top, a support ring 1, a first bearing 6, a lower rotating ring 2, a second bearing 7, a middle rotating ring 3, a third bearing 8, an upper rotating ring 4, a fourth bearing 9, and a base plate 5. Multiple drive units 13 are provided inside the support column. The lower rotating ring 2, the middle rotating ring 3, and the upper rotating ring 4 each have their own drive unit 13. The drive units can drive the lower rotating ring 2, the middle rotating ring 3, and the upper rotating ring 4 to rotate independently and relative to their adjacent rotating rings, thereby changing the degree and direction of bending of the support column.

[0055] like Figure 1B As shown, when the seat plate rotates to an angle α that is tilted in a certain plane, the rotation angle of the lower rotating ring relative to the axis of the support ring is σ1, the rotation angle of the middle rotating ring relative to the normal axis of the lower rotating ring and its connecting surface is σ2, the rotation angle of the upper rotating ring relative to the normal axis of the middle rotating ring and its connecting surface is σ3, and the rotation angle of the seat plate relative to the normal axis of the upper rotating ring and its connecting surface is σ4. Furthermore, σ1, σ2, σ3, and σ4 satisfy the relationship described in Formula 1 above during rotation.

[0056] See Figure 5 The lower rotating ring 2 has a lower drive gear ring 17 fixed at its lower end, the middle rotating ring 3 has a middle drive gear ring 18 fixed at its lower end, and the base plate 5 has an upper drive gear ring 19 fixed at its lower end. The middle rotating ring 3 has a lower connecting gear ring 20 fixed at its upper end, and the upper rotating ring 4 has an upper connecting gear ring 21 fixed at its lower end. The lower connecting gear ring 20 and the upper connecting gear ring mesh with each other at a certain point, so when the middle rotating ring 3 rotates, it can simultaneously drive the upper rotating ring 4 to rotate.

[0057] The outer wall of the lower drive gear ring 17 is interference-fitted with the inner wall of the first bearing 6; the outer wall of the middle drive gear ring 18 is interference-fitted with the inner wall of the second bearing 7; the upper drive gear ring 19 is interference-fitted with the inner wall of the fourth bearing 9; and the lower end of the upper rotating ring 4 is interference-fitted with the third bearing 8. The outer walls of the first to fourth bearings are all fixedly disposed within the bearing sleeve 24, and the bearing sleeve 24 is fixedly connected to the upper end of the support ring or rotating ring below it.

[0058] The inner wall of the support ring 1 is fixedly provided with a first motor 14 via a support plate 25. A sun gear is fixedly provided on the output shaft of the first motor 14. A plurality of planetary gears are provided on the outer periphery of the sun gear to connect the sun gear and the lower drive gear ring 17. The sun gear and the planetary gears form a planetary gear set 22. Each rotating ring level unit has an independently set planetary gear set 22 with the same driving mode. A planetary gear carrier 23 for fixing the planetary gears is provided above the planetary gear set 22 of the upper rotating ring 4. The inner wall of the lower rotating ring 2 is fixedly provided with a second motor 15 via the support plate 25 of this level. The second motor 15 is driven and connected to the middle drive gear ring 18 via the planetary gear set 22. The inner wall of the upper rotating ring 4 is fixedly provided with a third motor 16 via the support plate 25 of this level. The third motor 16 is driven and connected to the upper drive gear ring 19 via the planetary gear set 22.

[0059] The seat plate 5 is also equipped with an independent vibration motor for providing vibration massage to the user. The vibration motor is communicatively connected to the control system.

[0060] Example 2

[0061] See Figure 6 Unlike Embodiment 1, in this embodiment, the first motor 14, the second motor 15 and the third motor 16 are fixed in a non-centralized manner against the side wall, and their output shafts are fixed with corresponding internal gears 27 directly connected to them. The gear ring and its corresponding rotating ring are driven by the internal gears.

[0062] Example 3

[0063] See Figure 7 Unlike embodiments 1 and 2, in this embodiment, the first motor 14, the second motor 15, and the third motor 16 are fixed in a non-centralized manner against the side wall, and the output shafts of the second motor 15 and the third motor 16 are perpendicular to the rotation axis of their corresponding rotating rings; and bevel gears 28 that match the flared gear rings are fixed on the output shafts of the second motor 15 and the third motor 16. The first motor 14 drives the lower drive gear 17 to drive the lower turntable 2 to rotate, and the second motor 15 and the third motor 16 respectively drive the bevel gears 28 connected to them to drive the middle rotating ring 3 and the upper rotating ring 4 to rotate independently.

[0064] Example 4

[0065] See Figure 8Unlike embodiments 1-3, this embodiment also includes a fourth motor 26, and a fourth drive gear ring 29 is provided at the bottom of the upper rotating ring 4, while the lower connecting gear ring 20 and the upper connecting gear ring 21 are omitted. The output shaft of the fourth motor 26 is drivenly connected to the fourth drive gear ring 29 via a bevel gear 28. The fourth motor 26 is used to rotate the upper rotating ring 4 when a gear connection between the lower surface of the base plate and the upper rotating ring 4 is not possible.

[0066] Example 5

[0067] See Figure 9 Based on embodiment 3, a universal joint 30 is further provided between the motor and the rotating ring to compensate for non-coaxial misalignment. The universal joint 30 can be an assembly structure known in the art.

[0068] Example 6

[0069] See Figure 10A , Figure 10B Unlike embodiments 1-5, each rotating ring structure in this embodiment consists of a circular ring and several supports 31 of different heights evenly spaced around its bottom. The bottom surface of the circular ring is provided with an elastic element with a certain coefficient of friction; in this embodiment, the elastic element is specifically a rubber ring 32. Replacing the toothed ring with an elastic element and replacing the rotating ring structure with a continuous wall structure with a rotating ring structure composed of a circular ring and supports can significantly reduce processing and material costs and make the seat lighter.

[0070] Example 7

[0071] like Figure 11 As shown, when the seat plate continuously performs the action of tilting to the desired angle in multiple planes in a certain orientation sequence, the seat plate can be made to undulate and rotate on the horizontal plane. Figure 11 An illustrative implementation is shown, with the central horizontal position being the default initial position of the seat plate. It can first move in the direction indicated by the solid arrow in the figure to achieve clockwise rotation, or it can move in the direction indicated by the dashed arrow in the figure or other feasible directions known to those skilled in the art to achieve rotation in a set manner.

[0072] Example 8

[0073] See Figure 12This embodiment provides a method for exercising the pelvic and lower back muscles using the dynamic chair described in the previous embodiment. In the initial state, the support column 1 of the dynamic chair remains vertical and does not bend, and the seat plate remains horizontal. When the sensing system 13 senses pressure on the seat plate, it feeds back the pressure signal to the control system 10. The control system 10 uses pre-stored user information, such as user weight and habitual sitting posture, such as sitting forward, sitting backward, or semi-reclining. The sensing system 13 can determine the user's sitting posture based on the perceived difference in pressure position. When the pressure signal matches the user information, the control system 10 determines that the dynamic chair is in use, waits to receive user instructions, and starts timing.

[0074] When a user instruction is received, the control system 10 sends a control signal to the motion system according to the instruction, and the motion system executes the motion mode selected by the user according to the control signal.

[0075] When the timer exceeds the preset waiting time and no user instruction is received, the control system 10 determines that the user has maintained the same sitting posture for a long time, and automatically sends a control signal to the motion system according to the preset program. The motion system then executes the preset motion mode according to the control signal.

[0076] The motion modes include various motion modes such as forward and backward tilting, lateral tilting, and rotation.

[0077] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
