Description

Technical Field

[0001] This application relates to the field of massage equipment, and more specifically, to a massage chair designed to prevent seat hogging. Background Technology

[0002] Shared massage chairs are a sharing economy product under the "smart internet + internet of things" model. Through intelligent hardware devices and cloud management platforms, they can realize multiple functions such as online reservation, unmanned service, and safe operation. Shared massage chairs usually adopt operable automated massage mechanisms that can automatically change position, position, massage depth, massage particles, and massage methods according to various factors such as the user's body shape, body type, and massage needs, providing users with a comprehensive massage service.

[0003] However, since shared massage chairs are usually located in densely populated urban areas, although it is convenient for users to find a nearby massage chair at any time, the massage chairs are often occupied by others who do not pay for them. This results in a waste of resources and causes continuous economic losses to the businesses that deploy shared massage chairs. Therefore, there is an urgent need to provide a massage chair with an anti-seat-occupancy function. Utility Model Content

[0004] The purpose of this application is to provide a massage chair that prevents users from occupying seats, thereby solving the problem that existing shared massage chairs are often occupied by others for rest but without actual consumption, causing economic losses to the business.

[0005] The embodiments of this application are implemented as follows:

[0006] A first aspect of this application provides an anti-seat-occupancy massage chair, including a chair frame, a seat cushion mechanism, a lifting mechanism, a drive component, a controller, and a pressure sensor. One end of the seat cushion mechanism is hinged to the chair frame, and the other end is connected to the lifting mechanism. One end of the lifting mechanism is hinged to the chair frame, and the other end is connected to the output end of the drive component. The fixed end of the drive component is fixedly connected to the chair frame. The pressure sensor is fixedly mounted on the seat cushion mechanism to acquire pressure signals from the seat cushion mechanism. The controller is electrically connected to both the pressure sensor and the drive component, and controls the drive component to move according to the pressure signals acquired by the pressure sensor. This causes the lifting mechanism to move relative to the chair frame, thereby lifting the seat cushion mechanism relative to the chair frame. This anti-seat-occupancy massage chair solves the problem of existing shared massage chairs being frequently occupied by others for rest without actual use, resulting in economic losses for businesses.

[0007] As one possible implementation, the controller is equipped with a timer, which is used to record the actual duration for which the pressure sensor continuously acquires pressure signals. The controller is also equipped with a preset duration. When the actual duration reaches the preset duration, the controller is used to control the drive component to move so that the seat cushion mechanism can be lifted.

[0008] As one possible implementation, when the pressure sensor starts acquiring a pressure signal, the controller controls the timer to start timing; when the pressure sensor stops acquiring a pressure signal, the controller controls the timer to stop timing.

[0009] In one possible implementation, the seat cushion mechanism includes a seat cushion body and a seat cushion support member. The seat cushion body is fixedly disposed on the top surface of the seat cushion support member. One end of the seat cushion support member is hinged to the chair frame, and the other end is connected to the lifting mechanism.

[0010] In one possible implementation, the lifting mechanism includes a rotating component and a connecting rod. The first end of the rotating component is hinged to the chair frame, the second end is hinged to the output end of the drive member, and the third end is hinged to one end of the connecting rod. The other end of the connecting rod is connected to the bottom surface of the seat cushion support member. The drive member drives the rotating component to move the connecting rod, so that the seat cushion support member drives the seat cushion body to move relative to the chair frame.

[0011] In one possible implementation, the rotating assembly includes a first rod, a second rod, and a third rod connected end to end in sequence, so as to form a triangular frame together through the first rod, the second rod, and the third rod; or, the rotating assembly is a triangular plate.

[0012] As one possible implementation, the orthographic projection of the connecting rod on the chair frame is either straight or curved.

[0013] In one possible implementation, the lifting mechanism further includes a support plate, the seat cushion support is stacked on the top surface of the support plate, the other end of the connecting rod is hinged to the bottom surface of the support plate, one end of the support plate is hinged to the chair frame, and the other end is provided with a roller, which makes rolling contact with the seat cushion support.

[0014] In one possible implementation, the number of lifting mechanisms is two sets, which are symmetrically distributed on the left and right sides of the chair frame. The two sets of lifting mechanisms are fixedly connected by a connector, and the output end of the drive component is hinged to the connector.

[0015] As one possible implementation, the driving component is a motor or an electric actuator.

[0016] The beneficial effects of the embodiments of this application include:

[0017] The anti-seat-occupancy massage chair includes a chair frame, a seat cushion mechanism, a lifting mechanism, a drive component, a controller, and a pressure sensor. One end of the seat cushion mechanism is hinged to the chair frame, and the other end is connected to the lifting mechanism. One end of the lifting mechanism is hinged to the chair frame, and the other end is connected to the output end of the drive component. The fixed end of the drive component is fixedly connected to the chair frame. The pressure sensor is fixedly mounted on the seat cushion mechanism to acquire the pressure signal of the seat cushion mechanism. The controller is electrically connected to both the pressure sensor and the drive component and is used to control the drive component to move according to the pressure signal acquired by the pressure sensor, so that the lifting mechanism moves relative to the chair frame, thereby lifting the seat cushion mechanism relative to the chair frame. When the massage chair is not in use, the seat cushion mechanism remains in a horizontal or slightly tilted normal state to facilitate user seating. When someone sits down but does not perform any payment action (such as not scanning a payment code or starting a massage program), the pressure sensor detects a continuous pressure signal and transmits it to the controller. The controller determines that "pressure exists but no payment instruction" is an "invalid seat occupation" state and sends an action command to the drive unit. The drive unit outputs power, causing the lifting mechanism to rotate upward around its hinge point with the chair frame. The lifting mechanism further pushes the free end of the seat cushion mechanism (the end furthest from the hinge point between the seat cushion mechanism and the chair frame) upward, causing the seat cushion mechanism to form a larger tilt angle (e.g., the front end remains unchanged while the rear end is raised). The tilted seat cushion mechanism cannot properly support the human sitting posture, thus forcing the invalid seat occupant to leave. When the pressure sensor detects that the pressure signal has disappeared (i.e., the seat occupant has left), the controller sends a reset command to the drive unit, and the lifting mechanism drives the seat cushion mechanism back to its normal state, waiting for the next valid user. This anti-seat-occupancy massage chair uses an automated "detection-control-execution" mechanism to precisely solve the problem of invalid seat occupation in shared scenarios. While reducing losses for businesses and lowering operating costs, it also takes into account user experience and equipment reliability, and has functional expandability, providing an efficient solution for the commercial operation of shared massage chairs.

[0029] Please refer to the reference. Figures 1 to 6 This application provides an anti-seat-occupancy massage chair 100, including a chair frame 1, a seat cushion mechanism, a lifting mechanism, a drive component 4, a controller, and a pressure sensor 21. One end of the seat cushion mechanism is hinged to the chair frame 1, and the other end is connected to the lifting mechanism. One end of the lifting mechanism is hinged to the chair frame 1, and the other end is connected to the output end of the drive component 4. The fixed end of the drive component 4 is fixedly connected to the chair frame 1. The pressure sensor 21 is fixedly mounted on the seat cushion mechanism to acquire pressure signals from the seat cushion mechanism. The controller is electrically connected to both the pressure sensor 21 and the drive component 4, and controls the drive component 4 to move according to the pressure signals acquired by the pressure sensor 21, thereby lifting the seat cushion mechanism relative to the chair frame 1 through the movement of the lifting mechanism. This anti-seat-occupancy massage chair 100 can solve the problem of existing shared massage chairs being frequently occupied by others for rest without actual consumption, causing economic losses to businesses.

[0030] It should be noted that the anti-seat-occupancy massage chair 100 includes a chair frame 1, a seat cushion mechanism, a lifting mechanism, and a drive component 4. The chair frame 1 serves as the overall skeleton of the massage chair, providing a foundation for fixing and installing the seat cushion mechanism, the lifting mechanism, and the drive component 4. The seat cushion mechanism, as the seating part that the user directly contacts (at least including the seat cushion), has one end hinged to the chair frame 1, allowing the seat cushion mechanism to rotate around the hinge point. The other end is connected to the lifting mechanism, forming a flip structure with "one end hinged and the other end adjustable." The lifting mechanism, as a transmission intermediary (such as the connecting rod 33 assembly or the push rod structure), has one end hinged to the chair frame 1, and the other end connected to the output end of the drive component 4 (such as a motor shaft or a cylinder piston rod). It can rotate around the hinge point under the drive component 4, thereby pushing the seat cushion mechanism to rise and fall. The drive component 4, as a power source (such as a motor, an electric push rod, or a cylinder), has its fixed end rigidly connected to the chair frame 1 to ensure stable power output. The output end transmits power to the seat cushion mechanism through the lifting mechanism.

[0031] The anti-seat-occupancy massage chair 100 also includes a controller and a pressure sensor 21. The pressure sensor 21 can be fixedly installed on the contact surface of the seat cushion mechanism (such as inside the seat cushion or under the surface fabric). It can detect the pressure signal on the seat cushion mechanism in real time (such as whether someone is sitting down and the amount of pressure). The pressure signal is converted into an electrical signal and transmitted to the controller. The controller, as the core control unit (such as a microcontroller or PLC), is electrically connected to the pressure sensor 21 and the drive unit 4 through wires or wireless means. It can receive the pressure signal from the pressure sensor 21, make judgments according to the internal logic, and then send action commands to the drive unit 4, such as start or stop, forward or reverse rotation, etc.

[0032] When the massage chair is not in use, the seat cushion mechanism remains in a horizontal or slightly tilted normal state to facilitate user seating. When someone sits down but does not perform any consumption operation (such as not scanning a payment code or starting a massage program), the pressure sensor 21 detects a continuous pressure signal and transmits it to the controller. The controller determines that "pressure exists but no consumption command" is an "invalid seat occupation" state and sends an action command to the drive unit 4. The drive unit 4 outputs power, causing the lifting mechanism to rotate upward around its hinge point with the chair frame 1. The lifting mechanism further pushes the free end of the seat cushion mechanism (the end away from the hinge point between the seat cushion mechanism and the chair frame 1) upward, causing the seat cushion mechanism to form a large tilt angle (such as the front end remaining unchanged while the rear end is raised). The tilted seat cushion mechanism cannot properly support the human sitting posture, thus forcing the invalid seat occupant to leave. When the pressure sensor 21 detects that the pressure signal disappears (i.e., the seat occupant leaves), the controller sends a reset command to the drive unit 4, and the lifting mechanism drives the seat cushion mechanism back to a normal state, waiting for the next valid user.

[0033] The core pain point of traditional shared massage chairs is "free use of rest space," meaning users sit down but don't initiate the consumption process, preventing the equipment from providing services to paying users and directly reducing equipment utilization efficiency and business revenue. The anti-occupancy massage chair 100 provided in this application uses a pressure sensor 21 to detect "sitting behavior" in real time. Combined with the controller's judgment of "consumption instructions," it can accurately distinguish between "valid consumption seating" (process initiated) and "invalid occupancy" (sit down without consumption). It actively removes invalid users by lifting the seat cushion mechanism, ensuring the equipment prioritizes services for paying users, significantly improving equipment utilization, and thus reducing economic losses for businesses due to invalid occupancy.

[0034] The lifting mechanism slowly tilts the seat cushion mechanism via drive component 4, rather than using violent vibrations or noise to drive the user away. This avoids causing user resentment due to rough actions, while gently conveying the signal that the user needs to use the device through the physical means of "tilting so that the user cannot sit down". At the same time, when an invalid user leaves, the seat cushion mechanism can automatically return to its normal state, without affecting the normal use of subsequent paying users. This balances the "anti-seat-hogging function" and "user experience", and also avoids mechanical wear and tear (such as loose parts or structural deformation) caused by frequent and violent actions.

[0035] The controller's logic program can be flexibly adjusted according to usage needs, such as setting a "pressure duration threshold" (e.g., only initiating the lifting action after 3 minutes of no consumption to avoid misjudgment) and "lifting angle grading" (e.g., adjusting the tilt angle based on the duration of seat occupation, first a slight tilt to remind the user, then a large tilt to drive them away); it can also be linked with the payment system and back-end management system of shared massage chairs, such as uploading "invalid seat occupation records" to the back-end to help merchants analyze peak usage periods and optimize equipment placement (e.g., moving the equipment to consumption areas with more precise foot traffic), further improving operational efficiency.

[0036] In summary, the Anti-Seat-Occupying Massage Chair 100 accurately solves the problem of invalid seat occupation in shared scenarios through an automated "detection-control-execution" mechanism. While reducing losses for merchants and lowering operating costs, it also takes into account user experience and equipment reliability, and has functional expandability, providing an efficient solution for the commercial operation of shared massage chairs.

[0037] As one possible implementation, the controller is equipped with a timer to record the actual duration for which the pressure sensor 21 continuously acquires the pressure signal. The controller is also equipped with a preset duration. When the actual duration reaches the preset duration, the controller controls the drive component 4 to move so that the seat cushion mechanism can be lifted.

[0038] It should be noted that the controller has a built-in timer (such as a hardware timing module or software timing program). When the pressure sensor 21 first detects a valid pressure signal (such as when the pressure value exceeds the threshold for determining whether to sit down, excluding interference such as slight touch or placement of objects), the timer automatically starts and begins timing, recording the actual duration of the pressure signal in real time (i.e., the continuous stay time from when the user sits down until the pressure disappears). At the same time, the controller pre-stores a "seat-occupancy trigger threshold duration" (i.e., a preset duration that can be adjusted according to operational needs, such as 3 minutes or 5 minutes). This preset duration is used to distinguish between "temporary short stays" (such as when a user passes by and briefly tries to sit down or tidies up items) and "invalid long-term seat occupancy" (such as continuously sitting down without consuming any items).

[0039] After the user sits down, the pressure sensor 21 detects the pressure signal and transmits it to the controller. After the controller determines that the pressure value is valid, it triggers the timer to start and begins to accumulate the actual time. The controller compares the actual time accumulated by the timer with the preset time in real time. If the actual time does not reach the preset time (e.g., sitting for 1 minute), even if there is no consumption operation, the controller determines it as "temporary stay" and does not trigger the action of the drive component 4. If the actual time reaches or exceeds the preset time (e.g., sitting for 5 minutes without starting the consumption program), the controller determines it as "invalid seat occupation". After determining it as "invalid seat occupation", the controller sends an action command to the drive component 4. The drive component 4 drives the seat cushion mechanism to lift up through the lifting mechanism. When the user leaves, the pressure sensor 21 detects that the pressure signal has disappeared. The controller simultaneously triggers the timer to be reset and sends a reset command to the drive component 4. The seat cushion mechanism returns to normal and waits for the next detection.

[0040] As one possible implementation, when the pressure sensor 21 starts acquiring a pressure signal, the controller controls the timer to start timing; when the pressure sensor 21 stops acquiring a pressure signal, the controller controls the timer to stop timing.

[0041] It should be noted that when a user sits down (or an object is placed on the seat cushion mechanism), and the pressure value detected by the pressure sensor 21 reaches the controller's preset "effective pressure threshold" (such as exceeding 5kg, 15kg, etc., excluding interference from dust, slight touch, etc.), that is, when "pressure signal acquisition begins," the controller immediately sends a start command to the timer. The timer starts accumulating time from "0" and records the duration of the current pressure signal in real time. When the user leaves the seat cushion mechanism (or removes an object from the seat cushion mechanism), and the pressure value detected by the pressure sensor 21 is lower than the "effective pressure threshold," that is, when "pressure signal acquisition ceases," the controller synchronously sends an end command to the timer. The timer stops timing and resets to zero (or temporarily stores the timing data and then resets to zero), waiting for the next pressure signal to trigger.

[0042] During the continuous timing process, the controller will compare the "actual duration accumulated by the timer" with the "preset duration" in real time. If the actual duration does not reach the preset duration, the pressure signal disappears (such as when the user leaves early), and the controller determines it as "temporary stay" and does not trigger the action of drive component 4. If the actual duration reaches the preset duration and the pressure signal still exists (such as when the user continues to sit without consuming), the controller immediately determines it as "invalid seat occupation" and triggers drive component 4 to lift the seat cushion mechanism.

[0043] As one possible implementation method, such as Figures 1 to 6 As shown, the seat cushion mechanism includes a seat cushion body 22 and a seat cushion support 23. The seat cushion body 22 is fixedly mounted on the top surface of the seat cushion support 23. One end of the seat cushion support 23 is hinged to the chair frame 1, and the other end is connected to the lifting mechanism.

[0044] It should be noted that the seat cushion mechanism includes the seat cushion body 22 and the seat cushion support 23. The seat cushion body 22, as the functional component that directly contacts the user, is typically composed of soft filling materials (such as sponge or memory foam) and surface fabrics (such as breathable mesh or leather). Its core function is to provide a comfortable seating experience. It can also integrate massage modules (such as rollers 31 or airbags) to achieve a massage function. The seat cushion body 22 can be fixed to the top surface of the seat cushion support 23 by adhesive, snaps, or bolts, ensuring that the seat cushion body 22 does not shift or loosen when the user sits down. The support member 23, as the "skeleton and transmission carrier" of the seat cushion mechanism, can be made of rigid materials (such as metal brackets or high-strength plastic frames) and has sufficient load-bearing strength (to withstand the weight of an adult and the force when lifting). Its structural design needs to be adapted to the connection requirements. That is, one end of it is hinged to the chair frame 1 through a hinge (such as a hinge or bushing) (forming a fixed rotation point to ensure that the seat cushion mechanism can rotate around the hinge point), and the other end is connected to the movable end of the lifting mechanism (such as the end of the connecting rod 33) through a pin, bolt, etc., becoming the "force point" for the lifting mechanism to push the seat cushion up and down.

[0045] When the drive component 4 drives the lifting mechanism to move, the movable end of the lifting mechanism will push the free end of the seat cushion support 23 (i.e. the end away from the hinge point between the seat cushion support 23 and the chair frame 1) upward or downward. Since one end of the seat cushion support 23 is hinged to the chair frame 1, it will rotate around the hinge point, thereby causing the seat cushion body 22 fixed on the top surface to rotate synchronously. When rotating upward, the seat cushion body 22 is lifted to drive away invalid occupants. When rotating downward, it can return to the normal state for valid users to sit down and use.

[0046] As one possible implementation method, such as Figures 1 to 6 As shown, the lifting mechanism includes a rotating assembly 34 and a connecting rod 33. The first end of the rotating assembly 34 is hinged to the chair frame 1, the second end is hinged to the output end of the drive member 4, and the third end is hinged to one end of the connecting rod 33. The other end of the connecting rod 33 is connected to the bottom surface of the seat cushion support member 23. The drive member 4 drives the rotating assembly 34 to move the connecting rod 33, so that the seat cushion support member 23 drives the seat cushion body 22 to move relative to the chair frame 1.

[0047] It should be noted that the lifting mechanism includes a rotating assembly 34 and a connecting rod 33. The rotating assembly 34 is a multi-point linkage structure (such as an L-shaped bracket and a triangular connecting rod 33), and has three functional hinge ends. The first end is hinged to the chair frame 1 via a hinge (such as a pin or hinge), forming a fixed rotation point to ensure that the rotating assembly 34 can rotate around this hinge point. The second end is hinged to the output end of the drive component 4 (such as the piston rod of the motor push rod or the crank connected to the motor shaft) via a hinge, and is the power input end to receive the push from the drive component 4. The third end of the rotating component 34 is hinged to one end of the connecting rod 33 via a hinge, serving as the power output end. This converts the rotation of the rotating component 34 into linear or oscillating motion of the connecting rod 33. The connecting rod 33 is a rigid transmission rod (such as a metal rod or a high-strength plastic rod). One end of the connecting rod is hinged to the third end of the rotating component 34, and the other end is connected to the bottom surface of the seat support 23 (usually at a position far from the hinge point between the seat support 23 and the chair frame 1). It serves as a "power transmission bridge" connecting the rotating component 34 and the seat support 23.

[0048] The fixed end of the drive component 4 is rigidly connected to the chair frame 1, and the output end can extend and retract in a straight line (such as an electric push rod) or rotate around an axis (such as a servo motor + crank). When the drive component 4 is activated, its output end pushes or pulls the second end of the rotating component 34, forcing the rotating component 34 to rotate around the first end (the hinge point with the chair frame 1). When the rotating component 34 rotates, the third end synchronously drives one end of the connecting rod 33 to make an arc motion. The connecting rod 33 then transmits the motion to the bottom surface of the seat cushion support 23, which finally pushes the seat cushion support 23 to flip around its hinge point with the chair frame 1, causing the seat cushion body 22 on the top surface to "lift up" (flip upward) or "reset" (flip downward).

[0049] As one possible implementation method, such as Figures 1 to 3 As shown, the rotating assembly 34 includes a first rod, a second rod, and a third rod connected end to end in sequence, so that the first rod, the second rod, and the third rod together form a triangular frame; or, in other embodiments, such as Figures 4 to 6 As shown, the rotating component 34 is a triangular plate. As one possible implementation, such as... Figures 1 to 3 As shown, the orthographic projection of link 33 onto chair frame 1 is a straight line; or, in other embodiments, such as Figures 4 to 6 As shown, the orthographic projection of link 33 onto chair frame 1 is curved. Those skilled in the art should be able to make reasonable selections and designs based on actual circumstances; no specific limitations are imposed here.

[0050] As one possible implementation method, such as Figures 1 to 6As shown, the lifting mechanism also includes a support plate 32, and a seat cushion support member 23 is stacked on the top surface of the support plate 32. The other end of the connecting rod 33 is hinged to the bottom surface of the support plate 32. One end of the support plate 32 is hinged to the chair frame 1, and the other end is provided with a roller 31. The roller 31 makes rolling contact with the seat cushion support member 23.

[0051] It should be noted that the lifting mechanism also includes a support plate 32, which is a rigid support plate (such as a metal plate or high-strength composite board). As a "transitional load-bearing layer" between the seat cushion support 23 and the connecting rod 33, it has the following connections and functions: First, the bottom surface of the seat cushion support 23 is in contact with the top surface of the support plate 32 (relative sliding can be achieved through a slide rail, guide groove, or direct contact), and the support plate 32 provides stable bottom support for the seat cushion support 23; Second, one end of the support plate 32 is hinged to the chair frame 1 via a hinge (to the seat...). The hinged ends of the cushion support 23 are located on the same side, forming a reference point for synchronous rotation. The other end is hinged to the other end of the connecting rod 33, so that the power of the rotating component 34 can be transmitted to the support plate 32 through the connecting rod 33. The roller 31 is installed on the end of the support plate 32 away from its hinge point with the chair frame 1 (such as being fixed to the mounting seat of the support plate 32 by a bushing). The rolling surface of the roller 31 is in direct contact with the bottom surface of the cushion support 23, and can roll freely around its own axis to realize rolling friction between the support plate 32 and the cushion support 23.

[0052] When the driving component 4 drives the rotating component 34 to rotate, the third end of the rotating component 34 pushes or pulls the free end of the support plate 32 (i.e., the end away from the hinge point between the support plate 32 and the chair frame 1) through the connecting rod 33. The support plate 32 rotates around its hinge point with the chair frame 1, and the roller 31 on it moves synchronously with the support plate 32. Since one end of the seat cushion support 23 is hinged to the chair frame 1 and the other end is in rolling contact with the roller 31, when the support plate 32 rotates, the roller 31 will roll along the bottom surface of the seat cushion support 23. At the same time, the rolling friction will drive the seat cushion support 23 to rotate synchronously around its hinge point, ultimately realizing the lifting of the seat cushion body 22 (the support plate 32 rotates upward and the roller 31 pushes the seat cushion support 23) or the reset (the support plate 32 rotates downward and the roller 31 drives the seat cushion support 23 to fall back). By converting "sliding friction" into "rolling friction" through the roller 31, the resistance of the relative movement between the two can be greatly reduced, and the stability and reliability of the lifting action can be improved.

[0053] As one possible implementation method, such as Figure 1 and Figure 4 As shown, there are two sets of lifting mechanisms, which are symmetrically distributed on the left and right sides of the chair frame 1. The two sets of lifting mechanisms are fixedly connected by a connector, and the output end of the drive unit 4 is hinged to the connector.

[0054] It should be noted that there are two sets of lifting mechanisms, and the two sets have completely identical structures (both include a rotating component 34, a connecting rod 33, a support plate 32, and a roller 31). They are installed on the left and right sides of the chair frame 1 respectively (based on the left and right direction when the user sits down). The installation positions of the two sets of lifting mechanisms and their connection points with the chair frame 1 and the seat cushion support 23 are completely symmetrical. For example, the first end of the rotating component 34 of the left lifting mechanism is hinged to the left edge of the chair frame 1, and the first end of the rotating component 34 of the right lifting mechanism is correspondingly hinged to the right edge of the chair frame 1, ensuring that the force and movement on both sides are synchronized.

[0055] The two ends of the connecting parts (such as rigid metal rods or rectangular frames) are fixedly connected (e.g., by bolting or welding) to the core components of the two sets of lifting mechanisms (which can be the second end of the rotating assembly 34 or a specific position of the connecting rod 33), connecting the two independent lifting mechanisms in series into a whole. The output end of the driving part 4 (such as the piston rod of the electric push rod) is not directly connected to a single lifting mechanism, but is hinged to the middle (or center of gravity) of the connecting parts through a hinge, forming a power transmission path of "driving part 4 - connecting part - two sets of lifting mechanisms".

[0056] When the controller controls the drive component 4 to move, the output end of the drive component 4 pushes or pulls the connector. Since the connector is fixed to the two sets of lifting mechanisms, it will synchronously drive the rotating components 34 of the two lifting mechanisms to rotate around their respective hinge points with the chair frame 1. The two rotating components 34 then push the bottom surfaces of the left and right sides of the seat cushion support 23 synchronously through their respective connecting rods 33, support plates 32, and rollers 31. Finally, the seat cushion support 23 is driven to rotate smoothly around its hinge point with the chair frame 1, realizing the symmetrical lifting or resetting of the seat cushion body 22, so as to apply a balanced thrust to the left and right sides of the seat cushion support 23 synchronously, thereby improving the stability and reliability of the lifting action.

[0057] The above description is merely an optional embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0058] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.
