[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The following is combined Figures 1-3 The zero-gravity seating device of this utility model includes a support assembly 100, a seat assembly 200, a first telescopic member 300, and a drive structure 400. The seat assembly 200 includes a seat body 210 and a footrest 220. The seat body 210 is connected to the support assembly 100, and the footrest 220 is rotatably connected to the seat body 210. One end of the first telescopic member 300 is connected to the footrest 220, and the other end is used to connect to the seat body 210 or the support assembly 100. The drive structure 400 is movably mounted on the footrest 220. The drive structure 400 is connected to the first telescopic device 300 in a transmission manner to drive the first telescopic device 300 to extend and retract. In this process, the drive structure 400 moves relative to the footrest 220, and the first telescopic device 300 extends and retracts accordingly to adjust and fix the relative angle between the footrest 220 and the seat body 210.

[0023] The zero-gravity seat device provided by this utility model, by directly setting the drive structure 400 on the footrest 220, allows users to reach and operate it in a natural sitting posture without bending over or struggling to find it, greatly improving the convenience of adjustment. Because the drive structure 400 is connected to the first telescopic device 300, continuous and stepless control of the telescopic range is achieved, enabling the footrest 220 to remain stable at any angle within its rotation range, thus meeting users' personalized needs for precise angles. This design solves the inconvenience of operation and the problem of fixed angles caused by traditional snap-on adjustments, significantly improving the comfort and user-friendliness of the footrest 220.

[0024] Understandably, referring to Figures 1 to 3 In some examples of this utility model, the drive structure 400 is a pedal movably mounted on the footrest 220. The pedal is connected to the first telescopic device 300 via the first transmission structure to drive the first telescopic device 300 to extend and retract. When the pedal moves relative to the footrest 220, the first telescopic device 300 can drive the footrest 220 to rotate relative to the seat body 210. When the pedal is fixed relative to the footrest 220, the footrest 220 is fixed relative to the seat body 210.

[0025] When the user applies pushing or retracting force to the pedal, the extension and retraction of the pedal directly drives the first telescopic device 300, thereby naturally adjusting the angle of the footrest 220. Similarly, it provides an intuitive and instinctive operating experience, enhancing the sense of interaction.

[0026] It should be noted that in this embodiment, the footrest 220 is rotatably connected to the seat body 210, meaning that the extension trajectory of the footrest 220 is an arc. When the footrest 220 is rotated downward and forward from the retracted state, its support surface can always conform to the natural curve of the user's calf and foot; providing continuous and even support from the thigh to the calf, effectively improving comfort, promoting blood circulation in the legs, avoiding the pressure caused by the unsupported area behind the knee, and achieving the key to a relaxed posture such as "zero gravity".

[0027] Of course, in some other examples, the drive mechanism 400 can also be an integrated pull ring, hidden under the lower edge of the footrest 220. When adjustment is needed, the user gently hooks the pull ring with their toe and then pulls it. This design maintains the simplicity and integrity of the footrest 220's appearance.

[0028] Understandably, referring to Figures 1 to 3 In this embodiment, the aforementioned pedal is located in the middle of the footrest 220, and the pedal is provided with anti-slip ridges. The pedal being located in the middle of the footrest 220 makes the foot push more balanced and the support more stable; at the same time, the anti-slip ridges can effectively increase the friction between the sole of the foot and the pedal, prevent the foot from slipping, and improve the safety of use; the combination of the two not only enhances the stability of use, but also improves comfort.

[0029] In this embodiment, the first transmission structure is a transmission rope. The transmission rope can be easily bent and bypass obstacles, adapting to the complex and narrow space layout inside the seat, and efficiently transmitting the action of the drive structure 400 to the first telescopic device 300; the rope transmission can absorb some vibration, making the adjustment process of the footrest 220 smoother and quieter, and improving the user experience.

[0030] Of course, in some other examples, the first transmission structure can also be a gear and rack structure, in which the movement of the drive structure 400 is driven by the gear to drive the rack to move linearly, thereby pushing or pulling the first telescopic device 300, which has high transmission efficiency and precise control.

[0031] Reference Figure 2 In this embodiment, the first telescopic member 300 is arranged at an angle, with one end of the first telescopic member 300 connected to the seat assembly 200 and the other end connected to the support assembly 100.

[0032] With the above structure, the inclined arrangement of the first telescopic member 300 efficiently converts its linear telescopic motion into angular rotation of the seat assembly 200, realizing stepless and smooth adjustment of the backrest angle.

[0033] Understandably, referring to Figure 1 and Figure 2 In some examples of this utility model, the seat body 210 is rotatably connected to the support assembly 100; The zero-gravity seat device also includes a second telescopic device 500 and an operating switch 600. One end of the second telescopic device 500 is connected to the seat body 210, and the other end is connected to the support assembly 100. The operating switch 600 is located on the support assembly 100 and is connected to the second telescopic device 500 in a transmission manner. The operation switch 600 drives the second telescopic device 500 to extend and retract, so as to adjust and fix the relative angle between the seat body 210 and the support assembly 100.

[0034] Because the operating switch 600 is connected to the second telescopic device 500, continuous and stepless control of the telescopic amount is achieved, so that the seat assembly 200 can be stably positioned at any angle within the rotation range, meeting the user's personalized needs for precise angles.

[0035] In this embodiment, the operating switch 600 is driven by the second telescopic device 500 through the second transmission structure. The second transmission structure is a transmission rope, which can be easily bent and bypassed obstacles, adapting to the complex and narrow space layout inside the seat, and efficiently transmitting the action of the drive structure 400 to the second telescopic device 500. The rope transmission can absorb some vibration, making the adjustment process smoother and quieter, and improving the user experience.

[0036] It should be noted that, in this embodiment, the operating switch 600 is any one of a knob, button, or touch switch, providing multiple options such as a knob (suitable for stepless adjustment), a button (momentary control), or a touch switch (modern technological feel), so that the product can be adapted to different market positioning and user preferences.

[0037] Understandably, referring to Figure 1 and Figure 2 In some examples of this utility model, both the first telescopic member 300 and the second telescopic member 500 are gas springs.

[0038] Specifically, it can be understood that there is a small unlocking pin at the base of the piston rod of the gas spring. When this pin is pressed, the valve inside the gas spring opens, allowing gas to flow and thus enabling it to extend and retract freely; when the pin springs back, the valve closes, and the gas spring is locked at its current length.

[0039] The function of the transmission rope is to remotely transmit the user's operations on the drive structure 400 and the operating switch 600 as "pressing" and "releasing" actions on the unlocking pin.

[0040] Understandably, referring to Figure 1 and Figure 2 In some examples of this invention, the first telescopic member 300 and the second telescopic member 500 are both located at the bottom of the seat assembly 200. Integrating both at the bottom of the seat assembly 200 greatly optimizes the space layout, making the entire seat device more compact and space-saving.

[0041] The telescopic end of the first telescopic member 300 is hinged to the footrest 220 of the seat assembly 200, and the fixed end of the first telescopic member 300 is hinged to the support assembly 100; the telescopic end of the second telescopic member 500 is hinged to the seat body 210 of the seat assembly 200, and the fixed end of the second telescopic member 500 is hinged to the support assembly 100. Of course, in some other examples, the corresponding hinge positions of the telescopic and fixed ends of the first telescopic member 300 and the second telescopic member 500 can be adjusted accordingly. For example, the fixed end of the first telescopic member 300 can be connected to the footrest 220, and the telescopic end can be connected to the seat body 210. This is not limited here.

[0042] Understandably, referring to Figures 1 to 3In some examples of this utility model, the opposite sides of the seat body 210 are rotatably connected to the support assembly 100. At least one of the rotatable connections between the opposite sides of the seat body 210 and the support assembly 100 is provided with a damping structure 700, which is configured to provide resistance to the relative rotation between the seat body 210 and the support assembly 100.

[0043] It can be understood that, in some embodiments, damping structures 700 are provided at the rotatable connection points between the opposite sides of the seat body 210 and the support component 100, or damping structures 700 are provided at the rotatable connection points between one side of the seat body 210 and the support component 100, which is not limited here.

[0044] By employing the aforementioned structure, the damping structure 700 effectively suppresses the acceleration caused by gravity during the rotation of the seat body 210 (along with the footrest 220 and the user), ensuring a smooth and uniform process of reclining or returning to center, preventing sudden drops or bounces, and significantly improving safety and a premium feel. It provides continuous support feedback to the user, keeping the seat stable at any angle, eliminating swaying, and making the user feel firmly supported, enhancing relaxation and a sense of security during rest. By controlling the rotation speed, the damping structure 700 transforms simple "rotation" into a "controllable and elegant posture change," mechanically improving the product's quality and the user's comfort.

[0045] When the seat assembly 200 is adjusted, the damping structure 700 enables it to rotate smoothly and slowly, enhancing the sense of luxury and safety of operation. The damping structure 700 can absorb minor impacts during rotation, making the movement smoother and quieter.

[0046] It should be noted that in this embodiment, the damping structure 700 can be a rotary damper. The rotary damper generates torque through the shear resistance of a viscous fluid (such as silicone oil). This torque is proportional to the angular velocity of the seat body 210, which can effectively suppress rapid rotation and ensure that the process of leaning back or returning to center is always smooth and uniform, completely eliminating harsh impacts or a sense of loss of control. Of course, the use of a magnetic damper is not excluded.

[0047] Understandably, referring to Figures 1 to 3 In some examples of this utility model, the support assembly 100 includes a movable base 110 and a support frame 120. The movable base 110 is provided with movable casters 111; the support frame 120 is provided with an armrest 121. The support frame 120 is connected to the movable base 110 and is rotatably connected to the seat assembly 200.

[0048] With the above structure, the movable base 110 is equipped with movable casters 111, which allows the entire support assembly 100 to be moved easily, making it convenient for use or storage in different positions; the armrests 121 on the support frame 120 provide stable gripping points for users when getting up, sitting down or moving, increasing the safety and convenience of use, and the armrests 121 are equipped with control switches for easy control; the support frame 120 is rotatably connected to the seat assembly 200, allowing the seat to rotate relative to the support assembly 100, making it convenient for users to adjust their sitting posture or change direction, improving the flexibility of use.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
