Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a multifunctional integrated operating table. Background Art

[0002] The operating table is used to provide stable support for patients, allowing them to maintain the proper position during surgery and ensure the smooth progress of the operation.

[0003] The existing patent with publication number CN117159306B discloses a length-adjustable operating table, which includes a base, a controller fixed on the base, and a fixed cushion provided on the upper part of the base. It also includes an extension component, which includes a mounting shell, a bidirectional drive component, and a leveling component. The mounting shell is fixed on the base, and the bidirectional drive component and the leveling component are built into the mounting shell. The bidirectional drive component is driven by a motor to push two sets of leveling components to extend from both ends of the mounting shell, so that it can adjust the length of the operating table, and then the movable cushion is pushed upward by the electric lifting mechanism to keep the upper surface of the movable cushion and the fixed cushion flat, thereby improving the patient's comfort, saving storage space of the operating table, and enhancing its practicality.

[0004] However, when the length of the multifunctional integrated operating table in the prior art, including the aforementioned patent, is adjusted, if the patient is already lying on the operating table, the telescopic portion will generate friction with the human body. When the extension assembly is extended, the relative displacement of the movable cushion and the fixed cushion will directly affect the contact area of ​​the human body. Because the movable cushion needs to be adjusted for flatness by a lifting mechanism, relative friction will be generated between the human body and the surface of the movable cushion during the extension and retraction process. Especially in surgical scenarios where the human body cannot actively cooperate with movement, the external force generated by friction may affect the stability of the surgical site, increase the difficulty of operation for medical staff, and cause additional discomfort and potential risks to the patient. Summary of the Invention

[0005] Based on this, it is necessary to provide a multifunctional integrated operating table to address the problem that when the length of the current multifunctional integrated operating table is adjusted, the movement of the extension component causes friction between the patient and the surface of the operating table.

[0006] The above purpose is achieved through the following technical solutions:

[0007] A multifunctional integrated operating table, comprising:

[0008] A support platform is provided with a soft cushion, and the soft cushion covers the surface of the support platform.

[0009] Two movable platforms are located at both ends of the support platform. The movable platforms and the support platform can slide relative to each other. The movable platforms move forward away from the middle area of ​​the support platform to extend the effective length of the support platform for supporting the human body.

[0010] A flexible covering layer, wherein the flexible covering layer covers the surface of the mobile platform, one end of the flexible covering layer is fixedly connected to the soft pad, and the other end of the flexible covering layer is provided with a movable plate, and the movable plate is slidably connected to the mobile platform. The other end of the flexible covering layer slides relative to the mobile platform through the movable plate, and the flexible covering layer is always in a tensioned state.

[0011] A driving component is used to provide power for the mobile station.

[0012] Furthermore, it also includes an elastic airbag, which is fixedly connected to the mobile platform. When the mobile platform moves forward, the elastic airbag is inflated to support the human body. When the mobile platform moves backward, the elastic airbag is exhausted to compress and store.

[0013] Furthermore, the movable plate is fixedly provided with a squeezing roller, and the squeezing roller abuts against the surface of the elastic airbag to squeeze the elastic airbag to accelerate exhaust when the movable platform moves in the reverse direction.

[0014] Furthermore, a sliding plate is slidably provided on the movable platform, the sliding plate is fixedly connected to the movable platform, the sliding plate and the movable platform surround and form a sliding chamber, and the sliding chamber can be connected to the elastic airbag.

[0015] Furthermore, it also includes a trigger component, which moves synchronously with the mobile platform. The trigger component is used to detect the human body so that the moving distance of the mobile platform driven by the driving component matches the height of the human body.

[0016] Furthermore, the trigger assembly includes a start plate, which is slidably connected to the movable platform, and is provided with a vent and a one-way valve. The start plate has a start position and a close position. When the start plate is in the start position, the vent is connected to the elastic airbag and the sliding chamber; when the start plate is in the close position, the one-way valve is connected to the elastic airbag and the sliding chamber.

[0017] Furthermore, the trigger assembly includes a first elastic member, which is fixedly connected to the starting plate and the movable platform. The elastic force of the first elastic member always causes the starting plate to be located in the closed position or to have a tendency to approach the closed position.

[0018] Furthermore, the trigger component includes a first sensor, which is located in the sliding chamber. The driving component detects pressure data in the sliding chamber through the first sensor to control the stop position of the forward movement of the mobile platform.

[0019] Furthermore, the driving assembly includes a square rod and a threaded rod, the square rod and the threaded rod are slidingly connected, and the threaded rod is rotationally connected to the moving platform.

[0020] Furthermore, the trigger component includes a second sensor, and the driving component detects the rotational resistance of the threaded rod and the moving platform through the second sensor to control the stop position of the reverse movement of the moving platform.

[0021] The beneficial effects of the present invention are:

[0022] This invention provides a multifunctional integrated operating table. By arranging a movable platform and a flexible covering layer, when the movable platform moves forward to extend the support platform, the flexible covering layer adapts to the platform's displacement through the passive sliding of the movable plate. The movable platform pulls the flexible covering layer from beneath the support platform and spreads it flat across the movable platform surface, forming an extended surface of the cushion. During this process, the flexible covering layer remains relatively stationary at all times in contact with the human body, avoiding direct friction with the body during the raising, lowering, or retracting of the movable cushion in traditional solutions.

They are not intended to indicate or imply that the device or component being referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0041] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0042] Refer to the following Figures 1-10 The multifunctional integrated operating table provided in an embodiment of the present invention is described.

[0043] like Figures 1-8 As shown, the multifunctional integrated operating table provided by the embodiments of the present invention is particularly suitable for various surgical scenarios. Its adjustable length allows for flexible adaptation to different surgical requirements and patient body shapes. Of course, the multifunctional integrated operating table can also be used for other medical examinations, rehabilitation treatments, and other related operations that require flexible adjustment of the support structure and spatial layout.

[0044] Specifically, the multifunctional integrated operating table includes a base 100, a support table 200, and a cushion 210. The base 100 serves as the installation foundation for the entire operating table and is fixedly mounted on the ground or other fixed surface. The support table 200 is located above the base 100 and is used to support the human body, enabling various adjustment actions such as raising and lowering, and extending and retracting the operating table. The cushion 210 is laid on the surface of the support table 200 and directly contacts the patient's body. The cushion 210 is used to provide a comfortable lying experience for the patient, dissipate body pressure, and avoid discomfort or injury caused by local pressure on the patient's body during long operations.

[0045] When adjusting the length of an existing multifunctional integrated operating table, if the patient is already lying on the operating table, when the extension component is extended, the relative movement of the movable cushion and the fixed cushion will directly act on the human body contact area. During the extension and retraction process, relative sliding friction will occur between the human body and the surface of the movable cushion, which can easily pull the patient's skin, causing unnecessary pain and potential injury risks to the patient.

[0046] Based on this, the multifunctional integrated operating table provided in an embodiment of the present invention includes multiple mobile platforms 300, a flexible covering layer 310 and a driving assembly 500. The multiple mobile platforms 300 are used to extend the effective length of the support platform 200 to support the human body. The flexible covering layer 310 is used to reduce the friction between the human body and the extended part when the mobile platform 300 moves. The driving assembly 500 is used to provide power for the movement of the mobile platform 300.

[0047] Specifically, multiple movable platforms 300 are located at both ends of the support table 200 and can slide relative to the support table 200. The movable platform 300 has a first stroke and a second stroke. When the movable platform 300 is in the first stroke, the driving component 500 drives the movable platform 300 to move forward toward the extended position of the support table 200, so that the operating table has a larger area to fully support the patient's body. When the operating table can complete supporting the patient's body, the first stroke ends and the support table 200 is in an extended state.

[0048] When the movable table 300 is in the second stroke, the driving assembly 500 drives the movable table 300 to move in the opposite direction toward the center position of the support table 200. The area of ​​the operating table that can support the patient's body gradually decreases until the movable table 300 moves to the initial position. The second stroke ends and the support table 200 is in the initial state.

[0049] A flexible cover layer 310 covers the surface of the mobile platform 300 and has a fixed end and a movable end. The fixed end of the flexible cover layer 310 is fixedly connected to the cushion 210, and the movable end of the flexible cover layer 310 is provided with a movable plate 320. The movable plate 320 is slidably connected to the mobile platform 300, and the movable end of the flexible cover layer 310 slides relative to the mobile platform 300 via the movable plate 320.

[0050] In one embodiment, an elastic return member (not shown in the figure) is provided between the movable platform 300 and the movable plate 320. One end of the elastic return member is fixedly connected to the movable plate 320, and the other end of the elastic return member is connected to the end of the movable platform 300 close to the support platform 200. The elastic force of the elastic return member always makes the movable plate 320 approach the movable platform 300 or has a tendency to approach the movable platform 300.

[0051] When the movable platform 300 is in its first stroke, the drive assembly 500 drives the movable platform 300 in a forward motion. The fixed end of the flexible cover layer 310 and the cushion 210 remain stationary. Under the action of the movable platform 300, the movable end below the movable platform 300 causes the movable plate 320 to overcome the elastic force of the elastic return element, driving the movable end toward the edge of the movable platform 300. This causes the flexible cover layer 310 originally located below the movable platform 300 to move to the extended surface of the cushion 210 to support the patient's body. At this time, the elastic return element is in a stretched state, ensuring that the flexible cover layer 310 is smoothly deployed to support the patient's body.

[0052] When the movable platform 300 is in the second stroke, the driving assembly 500 drives the movable platform 300 to move in the opposite direction, and the elastic reset member drives the movable plate 320 to drive the movable end of the flexible covering layer 310 to move toward the center position of the support platform 200, so that the flexible covering layer 310 located on the extension surface of the soft pad 210 moves to the bottom of the soft pad 210 and resets.

[0053] The driving assembly 500 serves as a power source in the multifunctional integrated operating table, and provides power for the movement of other components, including but not limited to the movement of the moving table 300.

[0054] It is understood that the drive assembly 500 can be a common drive form, such as an electric motor, an internal combustion engine, etc. The power source in the drive assembly 500 can be centralized, transmitting power to other components through a transmission structure; or the power source can be decentralized, with multiple decentralized power sources driving each component separately.

[0055] Therefore, when the movable platform 300 adjusts the length of the support platform 200, the flexible covering layer 310 moves along with the movement of the movable platform 300, and the portion of the flexible covering layer 310 in contact with the human body will not be relatively displaced due to the movement of the movable platform 300, thereby avoiding relative friction between the human body and the extended portion when adjusting the length of the support platform 200.

[0056] Further, such as Figure 2-Figure 8 As shown, the multifunctional integrated operating table provided in an embodiment of the present invention further includes an elastic airbag 330. When the movable platform 300 moves forward, the elastic airbag 330 is inflated to support the human body. When the movable platform 300 moves backward, the elastic airbag 330 is deflated to be compressed and stored.

[0057] Specifically, the mobile platform 300, the support platform 200, the cushion 210, and the flexible cover layer 310 enclose a support area. The elastic airbag 330 is located in the support area and is fixedly connected to the mobile platform 300. When the mobile platform 300 is in the initial position, the elastic airbag 330 is compressed and stored in the support area. The mobile platform 300 is attached to the support platform 200 and the cushion 210 via the elastic airbag 330. When the mobile platform 300 moves away from the initial position, the elastic airbag 330 inflates to fill the support area.

[0058] The elastic airbag 330 is made of a high-strength, highly flexible, medical-grade rubber material, ensuring that when inflated, it can withstand the weight of the human body and maintain good shape stability. When deflated, the elastic airbag 330 is thin and fits snugly within the storage area, minimizing the space required.

[0059] When the platform 300 is in its first stroke, the drive assembly 500 drives the platform 300 in forward motion, and the elastic airbag 330 begins to inflate. The elastic airbag 330 gradually expands in the support area, and the portion of its surface bearing the weight of the person begins to adaptively deform based on the body's curves and pressure distribution, evenly distributing the person's weight and providing comfortable and stable support. When the platform 300 completes its first stroke, the elastic airbag 330 reaches the preset inflation pressure, providing continuous and stable support for the person.

[0060] When the moving platform 300 is in the second stroke, the gas in the elastic airbag 330 is quickly discharged. As the gas is discharged, the elastic airbag 330 gradually shrinks and becomes smaller, returning to a flat state and being located in the support area.

[0061] The flexible and deformable nature of the elastic airbag 330 allows it to conform to the body's surface when supporting a person, automatically adjusting its support strength based on the pressure distribution across different parts of the body, effectively dispersing the pressure. Furthermore, the elastic airbag 330 can be quickly deflated and compressed, making the retraction of the support platform 200 more flexible and convenient.

[0062] It is understood that the airbag 330 can be inflated using an external air source controlled by a micro-pump, a pneumatic valve, or a hydraulic-to-pneumatic pressure conversion device. These inflation methods must ensure stable inflation pressure and timely response, while also taking into account the safety and reliability of the surgical environment and meeting the requirements for adjusting the support force of the airbag 330 in different surgical scenarios.

[0063] In one embodiment, Figure 2-Figure 8 As shown, a squeezing roller 360 is provided on the moving platform 300 , and the squeezing roller 360 abuts against the surface of the elastic airbag 330 to squeeze the elastic airbag 330 to accelerate exhaust when the moving platform 300 moves in the reverse direction.

[0064] Specifically, the elastic airbag 330 is fixedly connected to one end of the mobile platform 300 near the middle of the support platform 200. The squeezing roller 360 is fixedly mounted on the support platform 200. The squeezing roller 360 divides the elastic airbag 330, which is placed in the support area, into a supporting portion and a fixed portion. The supporting portion contacts the flexible cover layer 310 to support the human body, while the fixed portion is located between the support platform 200 and the mobile platform 300 and does not contact the flexible cover layer 310.

[0065] When the moving platform 300 is in the first stroke, as the moving platform 300 moves forward, the fixed portion of the elastic airbag 330 gradually decreases and the supporting portion gradually increases. Gas is filled into the elastic airbag 330, causing the supporting portion of the elastic airbag 330 to gradually expand and support the human body.

[0066] When the movable platform 300 is in the second stroke, as the movable platform 300 moves in the reverse direction, the supporting portion of the elastic airbag 330 gradually decreases, while the fixed portion correspondingly increases. Because the squeezing roller 360 is located at the boundary between the supporting and fixed portions of the elastic airbag 330, the squeezing roller 360 squeezes the elastic airbag 330 as the supporting portion moves toward the fixed portion. The external force of the squeezing roller 360 causes the elastic airbag 330 to deform, compressing the internal space and rapidly expelling the gas.

[0067] Thus, the continuous squeezing action of the squeezing roller 360 allows the gas in the elastic airbag 330 to be discharged quickly, thereby accelerating the exhaust process.

[0068] It is understood that the component that squeezes the elastic airbag 330 may be a squeezing roller 360, or a squeezing plate, squeezing block, or other structure. These structures may be fixedly mounted on the support platform 200 or movably connected to the support platform 200. However, these structures should be able to deform the elastic airbag 330 by applying an external force when the movable platform 300 is in the second stroke, thereby accelerating the discharge of the gas inside.

[0069] In one embodiment, Figure 2-Figure 8 As shown, a sliding plate 350 is slidingly provided on the moving platform 300, and the sliding plate 350 is fixedly connected to the moving plate 320. The sliding plate 350 and the moving platform 300 surround and form a sliding chamber 340, and the sliding chamber 340 is used to realize the inflation and deflation of the elastic airbag 330 through the movement of the moving platform 300.

[0070] Specifically, the sliding plate 350 fits tightly against the inner wall of the moving platform 300 , so that the sliding chamber 340 is connected to the elastic airbag 330 . The moving plate 320 drives the sliding plate 350 and the moving platform 300 to slide relative to each other to adjust the volume of the sliding chamber 340 .

[0071] When the movable platform 300 is in its first stroke, it moves forward, causing the movable plate 320 at the movable end of the flexible cover layer 310 to drive the sliding plate 350 to slide forward relative to the movable platform 300. As the sliding plate 350 moves, the volume of the sliding chamber 340 decreases, and the gas within the sliding chamber 340 flows into the elastic airbag 330, completing the inflation process and providing stable support for the patient. After the movable platform 300 completes its first stroke, the gas pressures in the sliding chamber 340 and the elastic airbag 330 reach equilibrium, and the elastic airbag 330 maintains a constant supporting force.

[0072] When the movable platform 300 is in its second stroke, it moves in the reverse direction. The movable platform 300 and the support platform 200 compress the elastic airbag 330, causing the gas inside the elastic airbag 330 to be discharged into the sliding chamber 340. As the gas enters, the pressure inside the sliding chamber 340 increases, pushing the sliding plate 350 to slide in the opposite direction relative to the movable platform 300, increasing the volume of the sliding chamber 340 and completing the exhaust process. The elastic airbag 330 returns to its compressed and stored state. When the movable plate 320 abuts the movable platform 300, the drive assembly 500 stops, and the gas pressure in the sliding chamber 340 and the elastic airbag 330 reaches equilibrium, and the elastic airbag 330 remains in its contracted state.

[0073] Thus, the elastic airbag 330 is automatically inflated and deflated by the movement of the moving platform 300 through the sliding plate 350 and the sliding chamber 340 .

[0074] It can be understood that in this embodiment, an elastic reset member can be set between the movable platform 300 and the movable plate 320, so that when the movable plate 320 drives the sliding plate 350 to move, it is necessary to overcome the elastic force of the elastic reset member to achieve adjustment of the volume of the sliding chamber 340.

[0075] In one embodiment, the extension panels of existing multifunctional integrated operating tables are typically fixed and can only be fully extended or retracted, with no ability to precisely adjust to the patient's actual height. This makes it difficult for surgeons to determine the ideal operating table length based on individual patient differences during surgery. This not only affects patient comfort, but also limits the surgeon's field of view and ease of operation, hindering the smooth conduct of surgery.

[0076] Based on this, Figure 2-Figure 10 As shown, the multifunctional integrated operating table provided in an embodiment of the present invention further includes a trigger component 400, which moves synchronously with the moving platform 300. The trigger component 400 is used to detect the human body so that the driving component 500 drives the moving platform 300 to move a distance that matches the height of the human body.

[0077] Specifically, the trigger assembly 400 includes a starting plate 410 and a first elastic member 413. The starting plate 410 is provided with a vent 411 and a one-way valve 412. The starting plate 410 has a starting position and a closing position. When the starting plate 410 is in the starting position, the vent 411 connects the elastic airbag 330 and the sliding chamber 340, so that the sliding chamber 340 can inflate the elastic airbag 330; when the starting plate 410 is in the closing position, the one-way valve 412 connects the elastic airbag 330 and the sliding chamber 340, so that after the moving platform 300 completes the first stroke, the gas in the elastic airbag 330 is restricted from flowing back into the sliding chamber 340, and the gas in the elastic airbag 330 is allowed to be discharged into the sliding chamber 340 when the moving platform 300 moves in the opposite direction.

[0078] Actuating plate 410 is slidably connected to movable platform 300. A first elastic member 413 is disposed between the actuating plate 410 and movable platform 300. The first elastic member 413 is configured to automatically return the actuating plate 410 to the closed position after human pressure is removed. The elastic force of the first elastic member 413 always forces the actuating plate 410 to remain in the closed position or to tend toward the closed position.

[0079] The patient's body pressure acts on the actuating plate 410, overcoming the elastic force of the first elastic member 413 and causing the actuating plate 410 to move forward to the actuating position. When the elastic airbag 330 and the sliding chamber 340 are connected through the vent 411, the drive assembly 500 begins to drive the movable platform 300 forward, and the actuating plate 410 gradually moves away from the initial position following the movable platform 300. During this movement, the sliding chamber 340 injects gas into the elastic airbag 330 through the vent 411. When the actuating plate 410 is freed from the body's pressure, the elastic force of the first elastic member 413 pushes the actuating plate 410 in the opposite direction to the closed position, and the drive assembly 500 stops driving. At this point, the one-way valve 412 connects the elastic airbag 330 and the sliding chamber 340. Due to the one-way conduction characteristics of the one-way valve 412, the backflow of gas within the elastic airbag 330 is restricted, ensuring that the elastic airbag 330 can maintain stable support force.

[0080] When the moving platform 300 moves in the opposite direction, the moving platform 300 and the supporting platform 200 squeeze the elastic airbag 330, so that the pressure inside the elastic airbag 330 is greater than the pressure inside the sliding chamber 340. Under the action of the pressure difference, the gas pushes the one-way valve 412 to open, allowing the gas in the elastic airbag 330 to be discharged into the sliding chamber 340, thereby completing the exhaust process.

[0081] Thus, the activation plate 410 and first elastic member 413 use human body pressure as a trigger signal to automatically control the position of the activation plate 410, thereby controlling the connection between the elastic airbag 330 and the sliding chamber 340, thereby improving the system's automation and response speed. The provision of the one-way valve 412 effectively prevents gas backflow, ensuring that the elastic airbag 330 maintains stable support force after inflation.

[0082] It can be understood that when the one-way valve 412 connects the elastic airbag 330 and the sliding chamber 340, the one-way valve 412 can only be opened when the elastic airbag 330 needs to withstand a larger pressure to prevent the human body from applying pressure to the elastic airbag 330. The gas in the elastic airbag 330 will be discharged into the sliding chamber 340 through the one-way valve 412, causing the supporting force of the elastic airbag 330 to decrease, thereby weakening its supporting effect on the human body.

[0083] It is understood that the portion of trigger assembly 400 used to detect a human body can be a pressure sensor, or it can be a photoelectric sensor, ultrasonic sensor, or other component. For example, trigger assembly 400 can use an infrared pair of tubes to detect the proximity of a human body by transmitting and receiving infrared signals, thereby avoiding physical contact wear. Alternatively, it can use a laser radar to scan the human body's contours and accurately calculate the required extension length, enabling non-contact intelligent adjustment. These components can be fixedly mounted on mobile platform 300 or integrated into activation board 410, but all require sensing the human body's position or pressure to trigger the actuation logic.

[0084] It is understood that the first elastic member 413 is a spring or elastic rubber member, whose elastic force is directed along the sliding path of the activation plate 410. The first elastic member 413 can be a helical compression spring, generating a restoring force through linear deformation, or a wave spring, achieving high-load elasticity requirements with a small axial space. Furthermore, other components capable of storing and releasing elastic energy can be used in the present invention.

[0085] In one embodiment, Figure 2-Figure 8 As shown, the trigger assembly 400 includes a first sensor 420, which is located in the sliding chamber 340. The driving assembly 500 detects the pressure data in the sliding chamber 340 through the first sensor 420 to control the stop position of the forward movement of the moving platform 300.

[0086] Specifically, when the starting plate 410 is separated from the human body pressure, the sliding chamber 340 stops inflating the elastic airbag 330. At this time, as the moving platform 300 continues to move forward, the moving plate 320 at the moving end of the flexible covering layer 310 continues to drive the sliding plate 350 to move, causing the pressure in the sliding chamber 340 to continue to rise.

[0087] The first sensor 420 monitors the air pressure in the sliding chamber 340 in real time. When the air pressure reaches a preset threshold, the driving assembly 500 stops working, so that the moving platform 300 stops accurately.

[0088] Thus, by detecting the air pressure change in the sliding chamber 340 through the first sensor 420, the forward movement stop position of the moving platform 300 is precisely controlled, ensuring that the extension length of the support platform 200 and the supporting state of the elastic airbag 330 are in the optimal state.

[0089] In one embodiment, Figure 2-Figure 6 As shown, the driving assembly 500 includes a square rod 510 and a threaded rod 520, and the trigger assembly 400 includes a second sensor. The square rod 510 and the threaded rod 520 are slidably connected, and the threaded rod 520 is rotatably connected to the movable platform 300. The square rod 510 and the threaded rod 520 are used to convert the rotation of the square rod 510 into the movement of the movable platform 300. The driving assembly 500 detects the rotational resistance between the threaded rod 520 and the movable platform 300 through the second sensor to control the stop position of the reverse movement of the movable platform 300.

[0090] Specifically, the drive assembly 500 includes a drive motor 530, which is fixedly mounted in the middle of the lower wall of the support platform 200. The drive motor 530 is used to drive the square rod 510 to rotate about its own central axis. The square rod 510 is fixedly connected to the drive motor 530, and the square rod 510 is used to drive the threaded rod 520 to rotate. A threaded hole is provided at the lower end of the support platform 200 to cooperate with the threaded rod 520. The threaded rod 520 passes through the threaded hole. The interior of the threaded rod 520 is provided with a square hole that cooperates with the square rod 510. The threaded rod 520 is slidably connected to the square rod 510 through the square hole. The other end of the threaded rod 520 is rotatably connected to the movable platform 300.

[0091] When the square rod 510 rotates, the square rod 510 cooperates with the square hole inside the threaded rod 520, and the threaded rod 520 rotates synchronously with the square rod 510. Under the transmission action of the threaded hole, the threaded rod 520 moves axially while rotating. The axial movement of the threaded rod 520 directly drives the movable platform 300 and the support platform 200 to move relative to each other, thereby driving the movable platform 300 to adjust the length of the support platform 200.

[0092] The second sensor is located at the connection between the square rod 510 and the threaded rod 520 to detect the rotation resistance of the square rod 510 and the threaded rod 520 .

[0093] When the movable platform 300 moves in the reverse direction, the gas in the elastic airbag 330 is completely discharged into the sliding chamber 340. At this point, the movable platform 300 has returned to its initial position and cannot move further toward the center of the support platform 200. As the square rod 510 continues to drive the threaded rod 520 to rotate, the rotational resistance of the threaded rod 520 gradually increases due to the limited displacement of the movable platform 300. When the second sensor detects that the rotational resistance between the square rod 510 and the threaded rod 520 reaches a preset threshold, the drive motor 530 stops driving the square rod 510.

[0094] Therefore, by providing a second sensor to monitor the change in the rotational resistance of the square rod 510 and the threaded rod 520 , the moving platform 300 can be accurately controlled to stop moving, thereby avoiding damage to the mechanical structure or exceeding the travel limit due to overdriving.

[0095] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
