Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a standing-sitting posture conversion and rehabilitation training device. Background Technology

[0002] Providing rehabilitation training for patients with leg disabilities is a key method to help them regain leg function. Rehabilitation training for patients with leg disabilities requires the use of large medical rehabilitation equipment, through which the movement of the equipment drives the patient's legs to perform exercises such as swinging them back and forth.

[0003] However, large medical rehabilitation equipment is made of heavy components such as metal frames and large motors, making it difficult to move around freely and limiting patients to training in fixed locations. Portable, small rehabilitation training devices can solve this problem by reducing the size and weight of the device, allowing patients to use it at home for leg training. The training mechanisms in these devices can help patients perform active or passive leg swinging movements, thereby improving leg function.

[0004] However, rehabilitation training devices rely solely on user operation, making it difficult to switch between standing and sitting postures, thus hindering patients from achieving self-training. Furthermore, their complex structure and low ease of use reduce the user experience. Utility Model Content

[0005] This application provides a standing-sitting posture conversion and rehabilitation training device to solve the technical problems of difficulty in enabling patients to train independently and low ease of use.

[0006] This application provides a standing-sitting posture conversion and rehabilitation training device, including: a seat mechanism, a lifting mechanism, and a training mechanism. The seat mechanism has a symmetrical structure, including a seat plate and two side frames; the seat plate has track grooves on both sides, and the side frames have convex shafts on their inner sides, with the track grooves slidably connected to the convex shafts; the seat mechanism includes a first state and a second state, with the seat plate sliding along the convex shafts via the track grooves, causing the seat mechanism to transition from the first state to the second state; the lifting mechanism has a symmetrical structure, including two first movable units, two intermediate connecting rods, two second movable units, two fixed plates, and two push-pull units; each push-pull unit includes a push-pull rod; one end of the push-pull rod is connected to a first movable unit; one end of the first movable unit is rotatably connected to the side frame, the first... The other end of the movable unit is rotatably connected to the intermediate connecting rod and one end of the second movable unit; the other end of the second movable unit is rotatably connected to the fixed plate; the training mechanism has a symmetrical structure, including two first support arms, two second support arms, two crankshafts, two first connecting rods, two second connecting rods, and two third connecting rods; the first support arms are connected to the side frame, and one end of the first support arm, the second support arm, and the first connecting rod are rotatably connected; the other end of the first connecting rod, the first end of the third connecting rod, and the crankshaft are connected; the second end of the third connecting rod is rotatably connected to one end of the second connecting rod, and the other end of the second connecting rod is connected to the second support arm.

[0007] The aforementioned standing-sitting posture conversion and rehabilitation training device can enable users to switch between sitting and standing postures through a lifting mechanism. Furthermore, the device helps users perform rehabilitation training such as lower limb swinging through the cooperation of various components within the training mechanism, allowing users to train independently. The device is also lightweight and highly convenient.

[0008] In one possible implementation, a first pivot and a second pivot are provided on the outer side of the side frame; the first movable unit includes a first upper connecting rod and a second upper connecting rod; the first upper connecting rod includes a connecting hole on the rod; the second movable unit includes a first lower connecting rod and a second lower connecting rod; the fixed plate includes a third pivot and a fourth pivot; one end of a push-pull rod is connected to the first movable unit, including: the first end of the push-pull rod is rotatably connected to one end of the first upper connecting rod; one end of the first movable unit is rotatably connected to the side frame, including: the other end of the first upper connecting rod is rotatably connected to the first pivot; one end of the second upper connecting rod is rotatably connected to the second pivot; the other end of the first movable unit, an intermediate connecting rod, and one end of the second movable unit are rotatably connected, including: the first end of the intermediate connecting rod is rotatably connected to the connecting hole on the rod, the second end of the intermediate connecting rod is rotatably connected to the other end of the second upper connecting rod, the first end of the intermediate connecting rod is rotatably connected to one end of the first lower connecting rod, and the second end of the intermediate connecting rod is rotatably connected to the end of the second lower connecting rod; the other end of the second movable unit is rotatably connected to the fixed plate, including: the other end of the first lower connecting rod is rotatably connected to the third pivot; the other end of the second lower connecting rod is rotatably connected to the fourth pivot.

[0009] In the above device, both the first movable unit and the second movable unit are combined linkages. The first movable unit and the second movable unit are connected by an intermediate connecting rod, which allows them to change in height and angle after being driven by force, so as to realize synchronous raising or lowering and complete the conversion between standing and sitting postures.

[0010] In one possible implementation, the standing-sitting posture conversion and rehabilitation training device also includes a moving mechanism; the moving mechanism has a symmetrical structure, including two front wheels, two rear wheels and two motors; the motors drive the rear wheels and are connected to the crankshaft transmission via a coupling device.

[0011] The aforementioned device includes four motion wheels and a motor. The motor can provide multiple driving forces to control the switching of the sitting posture, the movement of the rehabilitation training device, and leg training, thereby enhancing the user's autonomy in activities.

[0012] In one possible implementation, the push-pull unit further includes: a power unit and a power connecting rod; the power unit is connected to a motor drive; one end of the power connecting rod is connected to the push-pull rod, and the other end of the power connecting rod is connected to the power unit.

[0013] In the above-mentioned device, the power unit transmits force to the first movable unit through the power connecting rod, and then transmits force to the intermediate connecting rod and the second movable unit through the first movable unit. The first movable unit, the intermediate connecting rod and the second movable unit cooperate with each other to achieve the adjustment of angle and height, thereby realizing the lifting function of the device.

[0014] In one possible implementation, the standing-sitting posture conversion and rehabilitation training device also includes an anti-tipping mechanism, which includes two connecting beams, a rear crossbeam, and two side supports; the connecting beams connect the front wheel and the rear wheel; the rear crossbeam connects the connecting beams; and the two side supports are respectively mounted on the two connecting beams and are movably connected to the connecting beams.

[0015] In the aforementioned device, when the standing-sitting posture conversion and rehabilitation training device is changed to a standing position, the rear crossbeam touches the ground, and at the same time, the side support moves from the connecting beam and supports the ground, realizing a multi-point stable support structure for the device at the rear, left, and right, preventing the device from tipping over and improving safety.

[0016] In one possible implementation, the outer surface of the seat plate is provided with a sliding band for assisting movement.

[0017] Since users need to exert force on their buttocks to raise or lower during the process of switching between standing and sitting postures, a sliding belt is installed on the surface of the seat to reduce the friction between the seat and the buttocks and to allow the user to move more smoothly with the seat. The sliding belt is driven by the raising and lowering of the seat, which helps the user switch between standing and sitting postures, thus improving the flexibility and comfort of the device.

[0018] In one possible implementation, the seat mechanism further includes: a backrest, two armrests, and two belly plates; the two ends of the backrest are respectively connected to two side frames; the armrests are mounted on the side frames; the belly plates are rotatably connected to the side frames; and the belly plates include locking units.

[0019] When the device is in a seated position, the back panel provides support to enhance user comfort, and the belly panel is retracted. When the device is in a standing position, the back panel provides support to enhance user safety, and the belly panel rotates along the connecting axis with the side frame to a position parallel to the back panel. When rotated into position, the belly panel is fixed by a locking unit to secure the user's body and enhance device safety.

[0020] In one possible implementation, the training mechanism further includes two foot pedals, two first baffles, and two second baffles; the two foot pedals are respectively hinged to two second support arms; the size of the foot pedals is adjustable; the two first baffles are respectively disposed on the two first support arms, and the two second baffles are respectively disposed on the two second support arms.

[0021] When using the standing-sitting posture conversion and rehabilitation training device, users can place their feet on the foot pedals to avoid friction with the ground when moving and to save energy during training. The adjustable foot pedals can accommodate various foot sizes, improving the device's versatility. The first and second baffles at the first and second support arms can prevent the user's legs from slipping off the support arms during training, enhancing the device's safety.

[0022] In one possible implementation, the seat, backrest, rear crossbeam, and foot pedals are foldable.

[0023] The seat, backrest, and rear crossbeam are designed as foldable structures that fold about the central axis. When pressure is applied from both sides, the standing-sitting posture conversion and rehabilitation training device can fold in half. The foot pedal is also a foldable structure that can be folded to both sides, reducing the space occupied by the device and improving its portability.

[0024] In one possible implementation, the standing-sitting posture conversion and rehabilitation training device also includes a safety belt; the safety belt is respectively installed on the seat mechanism, the first support arm, the second support arm and the foot pedal.

[0025] A seat belt is installed on the seat mechanism to secure the upper part of the user's body, a seat belt is installed on the support arm to secure the user's legs, and a seat belt is installed on the foot pedal to secure the user's feet, further preventing the user from detaching from the device while seated, thus improving the device's safety.

[0026] In one possible implementation, the first support arm is a telescopic structure, and the second support arm is a telescopic structure.

[0027] The first and second support arms are designed to be telescopic, allowing the length of the support arms to be adjusted so that the device can accommodate users with different leg lengths, thus improving the device's versatility.

[0028] In one possible implementation, the standing-sitting posture conversion and rehabilitation training device also includes a control mechanism; the control mechanism includes a control panel and a processor, the control panel being communicatively connected to the processor; and the processor being communicatively connected to a motor.

[0029] Users transmit control signals to the processor via the control panel. The processor then sends corresponding control signals to the motor, which drives the station's sitting posture conversion and rehabilitation training device to realize the user's operating commands, thus improving the device's convenience.

[0030] As can be seen from the above technical solutions, this application provides a standing-sitting posture conversion and rehabilitation training device, including: a seat mechanism, a lifting mechanism, and a training mechanism. The seat mechanism has a symmetrical structure, including a seat plate and two side frames; the seat plate has track grooves on both sides, and the side frames have convex shafts on their inner sides, with the track grooves slidably connected to the convex shafts; the seat mechanism includes a first state and a second state, with the seat plate sliding along the convex shafts via the track grooves, causing the seat mechanism to transition from the first state to the second state; the lifting mechanism has a symmetrical structure, including two first movable units, two intermediate connecting rods, two second movable units, two fixed plates, and two push-pull units; the push-pull unit includes a push-pull rod; one end of the push-pull rod is connected to the first movable unit; one end of the first movable unit is rotatably connected to the side frame, the first... The other end of the movable unit is rotatably connected to the intermediate connecting rod and one end of the second movable unit; the other end of the second movable unit is rotatably connected to the fixed plate; the training mechanism has a symmetrical structure, including two first support arms, two second support arms, two crankshafts, two first connecting rods, two second connecting rods, and two third connecting rods; the first support arms are connected to the side frame, and one end of the first support arm, the second support arm, and the first connecting rod are rotatably connected; the other end of the first connecting rod, the first end of the third connecting rod, and the crankshaft are connected; the second end of the third connecting rod is rotatably connected to one end of the second connecting rod, and the other end of the second connecting rod is connected to the second support arm.

[0031] The aforementioned standing-sitting posture conversion and rehabilitation training device can enable users to switch between sitting and standing postures through a lifting mechanism. Furthermore, the device helps users perform rehabilitation training such as lower limb swinging through the cooperation of various components within the training mechanism, allowing users to train independently. The device is also lightweight and highly convenient. Attached Figure Description

Detailed Implementation

[0037] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following examples do not represent all embodiments consistent with this application.

[0038] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0039] The terms "first," "second," "third," etc., used in the specification and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms can be used interchangeably where appropriate.

[0040] Rehabilitation training for patients with leg disabilities is a core means of restoring leg function. Currently, large-scale medical rehabilitation equipment is a commonly used training tool. It consists of a metal frame and large motors and other components, which can drive the patient's legs to complete movements such as swinging back and forth, simulating a normal walking posture, stimulating leg muscles, joints and nerves, and promoting functional recovery.

[0041] However, the heavy metal frames and large motors of large rehabilitation equipment make them bulky and difficult to move, limiting users to fixed locations, increasing rehabilitation costs and difficulty, and restricting training frequency and duration. Portable, small rehabilitation training devices can solve this problem: using lightweight materials and optimized structural design, they reduce size and weight, allowing users to train anytime. However, existing small rehabilitation training devices struggle to quickly switch between standing and sitting postures, making it difficult for patients to train independently, increasing rehabilitation difficulty and dependency. Furthermore, the complex structure and inconvenient operation of these devices reduce ease of use and negatively impact the user experience.

[0042] To address the issues of poor flexibility and low convenience in existing devices, this application provides a standing-sitting posture conversion and rehabilitation training device.

[0043] The standing-sitting posture switching and rehabilitation training device provided in this application embodiment achieves the switching between sitting and standing states through a lifting mechanism. It has a simple structure and is highly convenient to operate. When the device is in a standing state, the training mechanism can assist the user in lower limb training, including but not limited to standing training, walking training, and pedaling training. When the device is in a sitting state, the training mechanism can assist the user in other lower limb training, including but not limited to stretching training and positioning training. When the device is in a sitting state, a moving mechanism can also assist the user in moving freely, allowing the device to simultaneously serve as an aid to walking and a training device.

[0044] Figure 1 This is a schematic diagram of the structure of a standing-sitting posture conversion and rehabilitation training device provided in this application embodiment in the standing posture state.

[0045] Figure 2 This is a schematic diagram of the structure of a standing-sitting posture conversion and rehabilitation training device provided in this application embodiment in a sitting position.

[0046] like Figure 1 and Figure 2As shown, the standing-sitting posture conversion and rehabilitation training device includes: a seat mechanism, a lifting mechanism, and a training mechanism. The seat mechanism is a symmetrical structure, including a seat plate 101 and two side frames 102. The seat plate 101 has track grooves 1011 on both sides, and a convex shaft is provided on the inner side of the side frame 102. The track grooves 1011 are slidably connected to the convex shaft. The seat mechanism includes a first state and a second state. The seat plate 101 slides along the convex shaft via the track grooves 1011, allowing the seat mechanism to transition from the first state to the second state. The lifting mechanism is a symmetrical structure, including two first movable units, two intermediate connecting rods 201, two second movable units, two fixed plates 202, and two push-pull units. The push-pull unit includes a push-pull rod 2031. One end of the push-pull rod 2031 is connected to the first movable unit. One end of the first movable unit is rotatably connected to the side frame 102, and the other end of the first movable unit... The end of the intermediate connecting rod 201 is rotatably connected to one end of the second movable unit; the other end of the second movable unit is rotatably connected to the fixed plate 202; the training mechanism has a symmetrical structure, including two first support arms 301, two second support arms 302, two crankshafts 303, two first connecting rods 304, two second connecting rods 305, and two third connecting rods 306; the first support arm 301 is connected to the side frame 102, and one end of the first support arm 301, the second support arm 302, and the first connecting rod 304 is rotatably connected; the other end of the first connecting rod 304, the first end of the third connecting rod 306, and the crankshaft 303 are connected; the second end of the third connecting rod 306 is rotatably connected to one end of the second connecting rod 305, and the other end of the second connecting rod 305 is connected to the second support arm 302.

[0047] In some embodiments, the standing-sitting posture conversion and rehabilitation training device achieves standing-sitting posture conversion through a lifting mechanism and cooperates with the seat mechanism to change the user's posture. Specifically, when the device switches from a sitting state to a standing state: the push-pull unit receives the driving force of the motor, and the push-pull rod 2031 provides a pushing force to the first movable unit, causing the angle of the first movable unit to change and its height to increase; at the same time, the first movable unit transmits the force to the second movable unit through the intermediate connecting rod 201, causing the angle of the second movable unit to change and its height to increase; the first and second movable units rise in height simultaneously, so that the device is raised and converted to a standing state. During the process of raising the device, the seat plate 101 is subjected to an upward lifting force, and the track groove 1011 on the seat plate 101 slides on the convex shaft due to the force, gradually sliding from a position parallel to the ground to a position approximately perpendicular to the ground, providing an upward force to the user's buttocks, thereby causing the user's posture to change from a sitting posture to a standing posture.

[0048] Conversely, when the device switches from a standing to a sitting position: the push-pull unit receives the driving force from the motor, and the push-pull rod 2031 provides a pulling force to the first movable unit, causing the angle of the first movable unit to change and its height to decrease; simultaneously, the first movable unit transmits the force to the second movable unit through the intermediate connecting rod 201, causing the angle of the second movable unit to change and its height to decrease; the first and second movable units decrease in height simultaneously, allowing the device to descend and switch to a sitting position. During the descent, the seat plate 101 is subjected to a downward lifting force, and the track groove 1011 on the seat plate 101 slides on the convex shaft due to the force, gradually sliding from a position approximately perpendicular to the ground to a position parallel to the ground. At this time, the supporting force on the user's buttocks from the seat plate 101 gradually decreases, thereby causing the user's posture to change from a standing to a sitting position.

[0049] In some embodiments, to achieve changes in the height of the device, the first movable unit and the second movable unit may be a multi-link combination structure.

[0050] Specifically, the first movable unit includes a first upper connecting rod 2001 and a second upper connecting rod 2002; the first upper connecting rod 2001 includes a connecting hole 2003; the second movable unit includes a first lower connecting rod 2004 and a second lower connecting rod 2005; the side frame 102 is provided with a first rotating shaft 1021 and a second rotating shaft 1022 on its outer side; the fixing plate 202 includes a third rotating shaft 2021 and a fourth rotating shaft 2022; one end of the push-pull rod 2031 is connected to the first movable unit, including: the first end of the push-pull rod 2031 is rotatably connected to one end of the first upper connecting rod 2001; one end of the first movable unit is rotatably connected to the side frame 102, including: the other end of the first upper connecting rod 2001 is rotatably connected to the first rotating shaft 1021; the second upper connecting rod 2002... One end of the first movable unit is rotatably connected to the second rotating shaft 1022; the other end of the first movable unit, the intermediate connecting rod 201, and one end of the second movable unit are rotatably connected, including: the first end of the intermediate connecting rod 201 is rotatably connected to the connecting hole 2003 on the rod, the second end of the intermediate connecting rod 201 is rotatably connected to the other end of the second upper connecting rod 2002, the first end of the intermediate connecting rod 201 is rotatably connected to one end of the first lower connecting rod 2004, and the second end of the intermediate connecting rod 201 is rotatably connected to one end of the second lower connecting rod 2005; the other end of the second movable unit is rotatably connected to the fixing plate 202, including: the other end of the first lower connecting rod 2004 is rotatably connected to the third rotating shaft 2021; the other end of the second lower connecting rod 2005 is rotatably connected to the fourth rotating shaft 2022.

[0051] In some embodiments, the specific process of changing from a sitting posture to a standing posture through the first movable unit and the second movable unit is as follows: The push-pull rod 2031 provides an upward thrust to the first upper connecting rod 2001, causing the angle of the first upper connecting rod 2001 to change and its height to increase. The first upper connecting rod 2001 also drives the second upper connecting rod 2002 to change its angle and its height to increase. At the same time, the first upper connecting rod 2001 transmits force to the intermediate connecting rod 201 through the rod connecting hole 2003, causing the intermediate connecting rod 201 to rise upward while maintaining its angle perpendicular to the ground. The intermediate connecting rod 201 transmits the upward force to the first lower connecting rod 2004 and the second lower connecting rod 2005, causing the angle of the first lower connecting rod 2004 and the second lower connecting rod 2005 to change and its height to increase, thereby raising the overall height of the device and thus changing from a sitting posture to a standing posture.

[0052] Conversely, the specific process of changing from a standing to a sitting posture through the first and second movable units is as follows: The push-pull rod 2031 provides a downward pulling force to the first upper connecting rod 2001, causing the angle of the first upper connecting rod 2001 to change and its height to decrease. Simultaneously, the first upper connecting rod 2001 drives the second upper connecting rod 2002 to change its angle and decrease its height. At the same time, the first upper connecting rod 2001 transmits force to the intermediate connecting rod 201 through the rod connecting hole 2003, causing the intermediate connecting rod 201 to decrease downwards while maintaining its angle. The intermediate connecting rod 201 transmits the downward force to the first lower connecting rod 2004 and the second lower connecting rod 2005, causing the angle of the first lower connecting rod 2004 and the second lower connecting rod 2005 to change and their height to decrease, thus lowering the overall height of the device and achieving the change from a standing to a sitting posture.

[0053] It should be understood that the first movable unit and the second movable unit can also be other devices that can generate deformation, as long as they can change in angle and height after being subjected to force. No specific limitation is made in the embodiments of this application.

[0054] In some embodiments, the push-pull unit can provide the lifting mechanism with the force to achieve the conversion between standing and sitting postures. Specifically, the push-pull unit further includes: a power unit 2032 and a power connecting rod 2033; the power unit 2032 is connected to a motor drive; one end of the power connecting rod 2033 is connected to the push-pull rod 2031, and the other end of the power connecting rod 2033 is connected to the power unit 2032.

[0055] In some embodiments, the power unit 2032 can be connected to a motor drive, and the motor provides driving force to the power unit 2032. The power unit 2032 transmits the force to the push-pull rod via the power connection rod 2033.

[0056] It should be understood that the push-pull unit can also obtain driving force in other ways. For example, the power unit 2032 can move back and forth by its own motor, and this application embodiment does not specifically limit this.

[0057] For example, the standing-sitting posture conversion and rehabilitation training device may also include a transmission rocker arm. The user rotates the transmission rocker arm, which transmits the force to the power unit 2032 through the transmission mechanism (gear set, etc.), causing the push-pull rod 2031 to generate a pushing or pulling force, thereby realizing the conversion between the sitting and standing postures. The specific conversion method is the same as in the aforementioned embodiments, and will not be repeated here.

[0058] In some embodiments, during the transition from standing to sitting posture, since the seat 101 is a structure that provides upward support for the user, friction is generated between the user and the seat 101 as the user moves up or down, which can easily cause discomfort. Therefore, to reduce friction, a sliding belt is provided on the outer surface of the seat 101 to assist movement. The sliding belt generates transmission as the seat moves, thereby reducing friction and facilitating the transition from standing to sitting posture by the seat 101.

[0059] In some embodiments, the standing-sitting posture conversion and rehabilitation training device achieves lower limb training through a training mechanism. Specifically, a driving force is applied to the crankshaft 303, causing it to rotate. During rotation, the crankshaft 303 drives the first connecting rod 304 and the third connecting rod 306 to swing. After the third connecting rod 306 swings, it drives the second connecting rod 305 to swing. While swinging, the first connecting rod 304 and the second connecting rod 305 respectively drive the first support arm 301 and the second support arm 302 connected to them to swing, thereby driving the thigh and calf to swing. The first support arm 301 and the second support arm 302 are rotatably connected. When the first support arm 301 and the second support arm 302 are swung under force, they can cause the user's knee joint to bend, straighten, and other changes, thereby achieving the purpose of helping the user to perform lower limb activity training.

[0060] In some embodiments, the power of the training mechanism may come from an electric motor, which provides rotational force to the crankshaft 303. Specifically, the standing-sitting posture conversion and rehabilitation training device also includes a moving mechanism; the moving mechanism has a symmetrical structure, including two front wheels 401, two rear wheels 402, and two motors; the motors may be disposed in the rear wheels 402, driving the rear wheels and being connected to the crankshaft 303 via a coupling device.

[0061] It should be understood that rotational force can also be provided to the crankshaft 303 in other ways, and the embodiments of this application do not specifically limit this. For example, an energy storage mechanism can be provided in the device to store the force generated when the device moves or moves, and the energy storage mechanism can provide driving force to the crankshaft 303.

[0062] In some embodiments, the front wheel 401 and the rear wheel 402 are rolling wheels that can change angle. When driven by a force, they can move the entire device. The motor in the rear wheel 402 can provide driving force to the rear wheel 402, so that the rear wheel 402 can roll, thereby driving the front wheel 401 to roll, achieving the purpose of moving the device with four rolling wheels.

[0063] It should be noted that the motor can also be set in other locations, such as being fixed near the rear wheel 402, as long as it can transmit power. This application embodiment does not make any specific limitations.

[0064] It should be understood that, in addition to motor drive, other methods can be used to provide driving force to the front wheel 401 and rear wheel 402 to make the device move, and the embodiments of this application do not specifically limit this. For example, by pushing or pulling the rear armrest, the front wheel 401 and rear wheel 402 can be driven to roll.

[0065] For example, the rear wheel 402 can be set as a large-diameter rolling wheel, and an edge for gripping can be provided on the inner side of the rear wheel 402. When the user grips the edge, the force of the arm drives the rear wheel 402 to roll, which in turn drives the front wheel 401 to roll, so as to achieve the purpose of the front wheel 401 and the rear wheel 402 rolling and driving the device to move.

[0066] In some embodiments, the standing-sitting posture conversion and rehabilitation training device further includes an anti-tipping mechanism; the anti-tipping mechanism includes two connecting beams 501, a rear crossbeam 502 and two side supports 503; the connecting beams 501 connect the front wheel 401 and the rear wheel 402; the rear crossbeam 502 connects the connecting beams 501; the two side supports 503 are respectively disposed on the two connecting beams 501, and the side supports 503 are movably connected to the connecting beams 501.

[0067] When the standing-sitting posture conversion and rehabilitation training device is in the standing position, an anti-tipping mechanism is installed at the bottom of the device to ensure the user's safety during standing training. During the transition from a sitting to a standing position, the rear crossbeam 502 moves downwards until it supports the ground; simultaneously, the side support 503 located outside the connecting beam 501 rotates and supports the ground, thus forming a multi-point stable support structure on the rear, left, and right sides of the device. This prevents the device from tipping over due to improper force exerted by the user during training, improving the device's safety.

[0068] In some embodiments, the seat mechanism further includes: a backrest 103, two armrests 104 and two belly plates 105; the two ends of the backrest 103 are respectively connected to two side frames 102; the armrests 104 are disposed on the side frames 102; the belly plates 105 are rotatably connected to the side frames 102; the belly plates 105 include a locking unit 1051.

[0069] In some embodiments, to improve user stability on the device and ensure user safety, when the device is in a standing position, the locking unit 1051 can be unlocked, and the two abdominal plates 105 can be rotated toward the center of the device until they are parallel to the back plate 103, and then the locking unit 1051 can be locked. At this time, the abdominal plates 105 rest against the user's abdomen, applying a certain pressure to the user's abdomen to fix the user's upper body.

[0070] In some embodiments, the seat 101, back plate 103, rear crossbeam 502 and foot pedal 307 are foldable structures.

[0071] Specifically, the seat plate 101, back plate 103 and rear crossbeam 502 are all centrally symmetrical foldable structures. When an external force is applied, the entire device can be folded. The foot pedal 307 is also a foldable structure that can be folded to both sides, thereby reducing the overall space occupied by the device and improving its portability.

[0072] In some embodiments, the training mechanism further includes two foot pedals 307; the two foot pedals 307 are respectively hinged to two second support arms 302; the size of the foot pedals 307 is adjustable.

[0073] For example, in a seated position, the user's feet are placed on two foot pedals 307 respectively, which makes it convenient for the user to move while sitting on the device; and the user can apply pressure to the foot pedals 307 to drive the first support arm 301 and the second support arm 302 to swing, thereby realizing autonomous training in a seated position.

[0074] For another example, in a standing position, the user places both feet on the two foot pedals 307 respectively, using the foot pedals 307 as the point of force, without directly touching the ground or suspending in the air, to ensure the safety of training; and the user can apply pressure to the foot pedals 307 to drive the first support arm 301 and the second support arm 302 to swing, thereby realizing autonomous training in a standing position.

[0075] In some embodiments, the training mechanism further includes two first baffles 308 and two second baffles 309; the two first baffles 308 are respectively disposed on the two first support arms 301, and the two second baffles 309 are respectively disposed on the two second support arms 302.

[0076] Specifically, the first baffle 308 is used to block the user's thighs, and the second baffle 309 is used to block the user's calves, preventing the user from having an excessive range of motion in their legs due to improper force during lower limb training. Furthermore, the parts of the first baffle 308 and the second baffle 309 that come into contact with the user's body are made of flexible materials, further enhancing comfort during use.

[0077] In some embodiments, the standing-sitting posture conversion and rehabilitation training device further includes a safety belt; the safety belt is respectively disposed on the seat mechanism, the first support arm 301, the second support arm 302 and the foot pedal 307.

[0078] Specifically, the seat belts installed in the seat mechanism are used to secure the user's abdomen and other upper body parts, the seat belts installed in the first support arm 301 are used to secure the user's thighs, the seat belts installed in the second support arm 302 are used to secure the user's lower legs, and the seat belts installed in the foot pedal 307 are used to secure the user's feet, so as to prevent slippage caused by improper force during leg training and improve the safety of the device.

[0079] In some embodiments, the first support arm 301 is a telescopic structure, and the second support arm 302 is a telescopic structure.

[0080] Specifically, the first support arm 301 and the second support arm 302 can be adjusted according to the user's leg length to a length suitable for the user's training, so that the same device can be used by different users and improve the universality of the device.

[0081] In some embodiments, the standing-sitting posture conversion and rehabilitation training device further includes a control mechanism; the control mechanism includes a control panel 601 and a processor, the control panel 601 being communicatively connected to the processor; and the processor being communicatively connected to a motor.

[0082] For example, the control panel 601 includes a joystick and a training button. By controlling the joystick, the user transmits movement commands to the processor, which analyzes the commands and sends a signal to the motor, causing the motor to drive the rear wheel 402 to roll, thereby controlling the movement of the device. By pressing the training button, the user transmits training commands to the processor, which analyzes the commands and sends a signal to the motor, causing the motor to drive the crankshaft 303 to rotate, thereby causing the first support arm 301 and the second support arm 302 to swing.

[0083] In some embodiments, the control panel 601 may also include a training level adjustment button. The user can select different training levels by clicking the training level adjustment button and send the command to the processor. The processor adjusts the driving force according to the training level selected by the user to adapt to the patient's training needs.

[0084] In some embodiments, the control panel 601 may also include an emergency stop button for emergency braking. In an emergency, pressing the emergency stop button can stop the motor from driving, improving the safety of the device.

[0085] In some embodiments, the standing-sitting posture conversion and rehabilitation training device further includes a pressure sensor and an angle sensor. The pressure sensor is disposed on the foot pedal 307 to detect the pressure distribution on the user's feet and transmit the pressure data to the processor. The processor analyzes and determines whether the pressure data is within the normal range. When the pressure data exceeds the normal threshold, the processor issues a stop signal to stop the training action of the device and prevent accidents such as falls. The angle sensor is disposed between the first support arm 301 and the second support arm 302 to detect the angle between the two and transmit the angle data to the processor. The processor analyzes and determines whether the angle data is within the normal range. When the angle data exceeds the normal threshold, the processor issues a stop signal to stop the training action of the device and prevent accidents such as excessive stretching angle.

[0086] In some embodiments, the angle sensor can also work in conjunction with the processor to adjust the training level.

[0087] For example, when a user selects a specific training level, the processor controls the motor to drive the crankshaft 303 to rotate, causing the first support arm 301 and the second support arm 302 to swing. The angle sensor collects the angle data between the first support arm 301 and the second support arm 302 and transmits the angle data to the processor. When the processor analyzes that the angle data matches the current training mode, it controls the motor to stop driving.

[0088] In some embodiments, the processor of the control mechanism may also integrate a voice recognition module, a data storage module, a GPS module, a virtual reality module, etc., to enhance the user experience.

[0089] Specifically, the voice recognition module controls the device by recognizing the user's voice signals, such as "adjust the training mode to level one" or "play music"; the data storage module stores the user's training data and rehabilitation progress; the GPS module locates the device and transmits the location data in real time to other devices that communicate with the standing-sitting posture conversion and rehabilitation training device via wireless communication; and the virtual reality module connects to an external display device to integrate the user's walking movements into a virtual scene, enhancing the fun of training.

[0090] In some embodiments, the standing-sitting posture conversion and rehabilitation training device may also include sensors such as heart rate sensors and electromyography sensors for detecting the user's physiological data. These sensors transmit physiological data to a processor, which analyzes the physiological data and determines the training mode suitable for the user's current state.

[0091] In some embodiments, the standing-sitting posture conversion and rehabilitation training device may further include a display panel for dynamically displaying training data and the user's current status. For example, the processor displays data collected by an angle sensor, pressure sensor, heart rate sensor, and electromyography sensor on the display panel for easy observation by the user.

[0092] In some embodiments, the standing-sitting posture conversion and rehabilitation training device may also include a remote control panel for operation by others other than the user, thereby improving the operability and convenience of the device.
