Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rehabilitation equipment, and in particular to an auxiliary weight-reducing support system and a following rehabilitation training system. BACKGROUND

[0002] Rehabilitation training is crucial for a training object with lower limb movement dysfunction caused by stroke or other accidents to recover the ability to walk.

[0003] At present, the support methods of lower limb rehabilitation training equipment mainly include two types, one of which is to bind the training object to the equipment for training through the method of suspension weight reduction; the other type is that the training object wears the lower limb rehabilitation training equipment and then supports the exoskeleton equipment and the body weight through a hand-held walking stick for training.

[0004] For the support method of suspending the training object, the freedom of movement of the training object is limited, and the suspension strap is easy to hurt the training object, causing secondary injury to the training object. Importantly, the training object cannot achieve the training of overall coordination. The training object performs rehabilitation training in place, and the rehabilitation effect and the psychological feeling of the training object are different from "real walking on the ground".

[0005] And the lower limb rehabilitation training equipment through the walking stick training method needs the training object to use the walking stick through the strength of the upper limbs of the training object, and needs the training object to have strong arm strength, which can only be used for lower limb paralysis, but the training object with healthy upper limbs, such as training objects with stroke, hemiplegia, brain injury, muscle weakness, etc., cannot use such exoskeleton equipment, which has great limitations. Moreover, walking with a walking stick is particularly prone to falling, and the safety of training is very low. Moreover, when balancing the exoskeleton with a walking stick, such lower limb rehabilitation training equipment cannot guarantee the normal motion law of the center of mass. In the rehabilitation training with a walking stick, the center of mass is controlled by the training object, which causes the motion law of the center of mass to be inconsistent with the motion law of the center of mass in normal walking, and the person needs to constantly intervene and adjust the problem through the walking stick.

[0006] The training effect of the lower limb rehabilitation training equipment with the above two types of support methods is not ideal, the safety is also relatively low, and there are problems such as complicated wearing and removing steps, and the training object is undoubtedly consumed a lot of physical strength of medical staff by frequent helping and carrying.

[0048] The assisted weight reduction support system and the follow-up rehabilitation system disclosed herein will be further described in conjunction with the drawings and specific embodiments. The advantages and features of the present application will become more apparent from the following detailed description and claims. It should be noted that the drawings are in very simplified form and are not precise in scale, and are solely for the purpose of facilitating an easy and clear understanding of the embodiments of the present application.

[0049] Referring to Figure 1 The present application provides a follow-up rehabilitation training system, which comprises an assisted weight reduction support control system 10A and a lower limb rehabilitation training device 10B, the lower limb rehabilitation training device 10B comprising a waist connecting platform 10C, and a support member in the assisted weight reduction support control system 10A connecting the waist connecting platform 10C to provide a support force for the waist connecting platform 10C, the waist connecting platform 10C being used to fix the waist or the hip of a training subject. The training subject is a person in need of gait training.

[0050] The lower limb rehabilitation training device 10B, as shown in Figure 1As shown, the exoskeleton robot, also known as an exoskeleton robot, can be worn on the human body and synchronized with the human body. The lower limb rehabilitation training device 10B can follow the movement of the training object during the walking movement of the training object to help the training object to carry out rehabilitation training. The lower limb rehabilitation training device 10B can include two sets of gait training mechanisms and a waist connecting platform. The two sets of gait training mechanisms are connected through the waist connecting platform. Each set of gait training mechanisms at least includes: a thigh rod, a shank rod, a hip joint assembly, a knee joint assembly, an ankle joint assembly, and a foot support assembly. The hip joint assembly is connected with the thigh rod through at least one rotary joint structure.

The ankle joint assembly is connected with the foot support assembly through at least one rotary joint structure. The rotary joint structure can rotate in a first plane in which the thigh rod and the shank rod are located. The hip joint assembly is connected with the waist connecting platform through a twisting joint structure. The twisting joint structure can rotate in a second plane. The second plane is perpendicular to the first plane. The rotation in the first plane is the sagittal plane freedom movement of the hip joint assembly, the knee joint assembly, and the ankle joint assembly. The rotation in the first plane is the transverse plane freedom movement of the hip joint assembly. The vertical here includes a 90-degree angle with each other, and also includes an approximate 90-degree angle. The hip joint assembly, the ankle joint assembly, and the knee joint assembly each at least include a power source and a transmission structure. The power source provides a power source for the transmission structure. The transmission structure connects the rotary joint structure, so that the rotary joint structure is driven by the power source to rotate in the first plane. It also includes a reset mechanism. One end of the reset mechanism is fixed on the hip joint assembly. The other end of the reset mechanism is fixed on the waist connecting platform. When the hip joint assembly moves in the transverse plane freedom, the reset mechanism is affected by the movement to change, limits the angle change between the hip joint assembly and the waist connecting platform within a predetermined range, and provides a restoring force to restore the angle between the hip joint assembly and the waist connecting platform to the initial position. The foot support assembly includes: a contact layer in contact with the ground and capable of providing a friction coefficient, and a foot support plate. The foot support plate at least includes a rigid support section. The foot support plate is fixedly connected with the contact layer. In some embodiments, the foot support plate is configured to be foldable at the forefoot segment; and / or, the foot support plate is further configured to be foldable at the rear foot segment. In some embodiments, the foot support plate is a multi-section structure. At least a part of the multi-section structure is a rigid support section. At least a part of the multi-section structure is an elastic support section. The elastic support section is provided at the forefoot and / or the rear foot. The foot support assembly can directly contact the ground to simulate the human foot walking on the ground, instead of moving on the running belt of the treadmill, so that the rehabilitation training is closer to the real walking.

[0051] Figures 2 to 12The application provides a specific implementation of the assisted weight loss support control system 10A. The assisted weight loss support control system 10A comprises a base, a main frame, a support and an adjusting assembly. The main frame is fixed to the base; the support is slidable along the main frame in a first range; and the adjusting assembly controls the support to slide along the main frame to a set position, the support moves relative to a support surface in a second range under the action of the adjusting assembly, and outputs a support force. Here, the sliding refers to the movement along the main frame. The movement here refers to the random or fixed frequency dynamic movement. The set position here is related to the height of the training object, and the height of the hip or waist of the training object is used to determine the set position to which the support is slid along the main frame. The support surface here includes but is not limited to the ground. The specific implementation of the assisted weight loss support control system 10A will be described in detail below.

[0052] Referring to the drawings Figures 2 to 4 An embodiment of the assisted weight loss support control system 10A according to the application is described. Figures 2 to 4 Various views of the assisted weight loss support system 100 according to the embodiment of the application are shown. The assisted weight loss support system 100 comprises a main frame 110, a base 1000, a support 120 and an adjusting assembly. The main frame 110 can be mounted on the base 1000 shown in FIG. Figures 2 to 4 The support 120 is slidable along the main frame 110 in a first range. The adjusting assembly controls the support to slide along the main frame 110 to a set position, and the support 120 moves relative to a support surface in a second range under the action of the adjusting assembly, and outputs a support force. The first range here corresponds to the height adjustment range of the hip or waist of different training objects.

[0053] The adjusting assembly controls the support 120 to slide along the main frame 110 in the upright direction, and adjusts the position of the support on the main frame according to the height of the hip or waist of different training objects, so that the assisted weight loss support system 100 is adapted to the height of different training objects. The set position is related to the height of the waist or hip of the current training object.

[0054] The main frame 110 serves as a structural frame to mount and connect the adjustment device. The main frame 110 is configured to support the entire adjustment device and the support 120, and to maintain the stability of the adjustment device and the support 120 during use. The main frame 110 can be configured as a rectangular frame having two vertical columns 111, 112 extending vertically, an upper beam 113 connecting upper ends of the columns 111, 112, and a lower beam 114 connecting lower ends of the columns 111, 112. The connections between the columns 111, 112 and the beams 113, 114 can be implemented by welding, riveting, screwing, or one-piece forming. The columns 111, 112 and the beams 113, 114 of the main frame 110 can define a receiving space therebetween. In some embodiments, the base 1000 further comprises a following frame 1100 and casters 1200, which can carry the auxiliary support weight reduction system 100 to move with the base 1000 as the training object walks.

[0055] The support 120 can be sleeved on the main frame 110 and can slide in the upright direction of the main frame 110, and can be adjusted in position on the main frame 110 according to the height of the hip or waist of different training objects, so that the auxiliary support weight reduction system 100 can be adapted to the height of different training objects. The support 120 can be connected to a lower limb rehabilitation training device worn by the training object or any part of the body of the training object, and is preferably fixedly connected to the waist or hip of the training object. The support 120 is fixedly connected to a waist connection platform of the lower limb rehabilitation training device worn by the training object. In some embodiments, as shown in Figures 2 to 4 The support 120 includes a contact body 121 provided with one or more connection features, such as a threaded hole, a blind hole, a through hole, a connecting lug, a pin, etc., to be fixedly connected to the waist connection platform of the lower limb rehabilitation training device worn by the training object. The contact body 121 protrudes from the receiving space defined by the columns 111, 112 and the beams 113, 114 of the main frame 110 and extends forward, so that the distance between the training object and the lower limb rehabilitation training device and the auxiliary support weight reduction system 100 can be maintained when the contact body 121 is fixedly connected to the lower limb rehabilitation training device worn by the training object, preventing interference. Preferably, the support 120 can be configured to include two contact bodies 121 symmetrically arranged with respect to the vertical center axis of the main frame 110 to evenly distribute the force. The support 120 can also be connected to the adjustment device and can serve to transmit the support force of the adjustment device, and is configured to provide a support force particularly opposite to the direction of gravity to the training object in the extension direction of the guide device 130 (i.e., the vertical direction) during rehabilitation training.

[0056] In some embodiments, as shown in Figures 2 to 4As shown, the adjusting assembly comprises a power adjusting device 150, which comprises a power device 151, a control device and a moving device, wherein the moving device is linked with the support 120, the control device controls the operation of the power device 151, and the operation of the power device 151 outputs a power source for driving the moving device to slide along the main frame 110 in a first range, and the moving device slides along the main frame 110 to drive the support 120 to slide along the main frame 110 to a set position.

[0057] The operation of the power device 151 outputs a power source for driving the moving device to drive the support 120 to move in a second range, or the power adjusting device 150 provides an elastic deformation force so that the support 120 can move in the second range relative to the support surface.

[0058] In some embodiments, as shown, Figures 2 to 4 The adjusting assembly further comprises a guide device 130, which is fixed to the main frame 110 and defines a track for the moving device and the support 120 to move vertically along the main frame 110.

[0059] In some embodiments, the moving device adopts a lead screw transmission mechanism. As shown, Figure 3 The moving device comprises a lead screw 152 and a sliding block 153, the sliding block 153 is movable along the lead screw 152, the power device 151 outputs a power source to drive the lead screw 152 to rotate and drive the sliding block 153 to slide along the lead screw 152, thereby driving the support 120 to slide along the main frame 110 in a direction along which the main frame 110 lies. The sliding block 153 is connected with the support 120. The lead screw 152 can be implemented as a ball screw or a trapezoidal screw, preferably a ball screw. The power device 151 can be implemented as an electric motor. In particular, the lead screw 152 is located between the two guide rails of the guide device 130, and is preferably located in the middle of the two guide rails of the guide device 130. The lead screw 152 is arranged parallel to the columns 111, 112 of the main frame 110 and the guide rails of the guide device 130, i.e. the axis direction of the lead screw 152 is consistent with the direction (i.e. the support direction) in which the guide device 130 defines the movement of the sliding block 153. The sliding block 153 is provided with a connecting device 1531 matched with the lead screw 152. The connecting device 1531 can be provided with a thread matched with the lead screw 152, so as to be threadedly connected to the lead screw 152, so that the rotation of the lead screw drives the sliding block 153 to slide in the support direction.

[0060] Alternatively, the connecting device 1531 can be implemented as a nut. The lead screw 152 can be arranged on the slider 153, preferably at a central position of the slider 153. Via the cooperation of the nut and the lead screw 152, the movement of the slider 153 can be realized under the action of the rotation of the lead screw 152. The rotation of the lead screw 152 can be controlled by the power device 151, and the rotation of the lead screw 152 is driven by the rotation of the power device 151 to realize the lifting or lowering of the slider 153, thereby driving the support 120 to slide along the main frame 110 in the direction of the main frame 110.

[0061] In particular, an elastic body providing elastic deformation force is further provided between the lead screw 152 and the slider 153. For example, the elastic adjusting device herein can be an elastic body arranged between the lead screw 152 and the slider 153. For example, the connecting device 1531 (e.g. nut) of the slider 153 can be connected to the slider 153 itself via the elastic body, so that the connection between the slider 153 and the lead screw 152 has a buffering feature. A force sensor can also be directly arranged between the lead screw 152 and the slider 153, for example between the nut and the movement unit or the elastic body, or a pressure sensor can be arranged between the elastic body and the movement unit to sense the support force.

[0062] The adjusting assembly further comprises a guide device 130 fixedly connected to the main frame 110 and defining the sliding direction (vertical direction or up-down direction) of the slider 153 and the support 120, for example defining the trajectory of the movement device and the support 120 for vertical movement along the main frame 110. The movement device is connected to the support 120 and can drive the support 120 to slide along the support direction of the main frame 110. Among them, the components of the adjusting assembly are basically positioned in the accommodation space defined between the columns 111, 112 and the beams 113, 114 of the main frame 110, and basically do not protrude beyond the accommodation space, as shown in Figure 4 to prevent interference with the movement of the training object during the rehabilitation training process.

[0063] The guide device 130 can be implemented as a guide rail extending upward from the lower beam 114 to the upper beam 113 between the columns 111, 112 of the main frame 110, preferably a pair of guide rails symmetrically arranged with respect to the vertical center axis of the main frame 110. The guide device 130 is fixedly connected to the upper beam and the lower beam of the main frame 110 at both ends. The guide device 130 is configured to define the movement direction and range of the slider 153 and the support 120. In particular, the guide device 130 defines the sliding direction of the slider 153 and the support 120 along the support direction of the main frame, for example the up-down direction.

[0064] In particular, the guide device 130 defines the movement direction of the slider 153 and the support 120, which can be achieved by a through hole formed in the movement device and the support 120 and sleeved on the guide device 130. Preferably, the cross-sectional shape of the through hole is consistent or at least substantially consistent with the cross-sectional shape of the guide rail of the guide device 130, so that the movement device and the support 120 can stably slide along the guide rail of the guide device 130.

[0065] Those skilled in the art should understand that the guide device 130 can also be implemented as a linear bearing and an optical axis, or as a limiting guide groove and the like. As long as the structure of the guide device 130 can define the movement direction of the movement device and make the movement device move in a specific direction, these alternative implementations of the guide device 130 are intended to be included in the scope of the present application.

[0066] In some embodiments, the movement device can also be provided with an elastic body (such as a spring and the like), for example, the slider 153 is connected to the support via the elastic body. A strain sensor can also be provided in the elastic body to sense the strain conducted to the elastic body by the support, and calculate the support force provided by the power adjusting device 150 based on the strain, and / or a displacement detection sensor can be provided on the movement device, for example, a displacement detection sensor is provided between the lead screw 152 and the slider 153 to sense the strain and calculate the support force provided by the power adjusting device 150 based on the strain. The provision of the displacement detection sensor means that the displacement detection sensor is arranged to detect the displacement of the slider 153 relative to the lead screw 152, without limiting the installation position of the displacement detection sensor and the like. The displacement detection sensor can be implemented as any suitable displacement sensor or distance measuring device in the art, such as a laser range finder, an infrared range finder, a linear displacement sensor, a pull rope displacement sensor, an LVDT displacement sensor, a magnetostrictive displacement sensor, and the like.

[0067] The elastic body can play a role of buffering during the fluctuation of the waist of the training object, preventing damage to the body of the training object. The strain sensor senses the strain in the elastic body (such as a spring), and the elastic modulus of the elastic body can be combined to calculate the stress of the elastic body, and the size of the elastic body and the like can be combined to calculate the stress in the elastic body, so as to calculate the size of the support force. In the case where the displacement detection sensor is provided between the lead screw 152 and the slider 153, the displacement can be sensed, and the size of the strain in the elastic body can be calculated based on the displacement, and then the size of the support force can be calculated.

[0068] The power adjusting device 150 is configured to drive the sliding block 153 to slide along the main frame supporting direction, and the movement of the sliding block 153 along the supporting direction drives the support 120 to slide along the supporting direction. By sliding the support 120 along the supporting direction, the support force directly applied to the training object by the support 120 can be adjusted.

[0069] The power adjusting device 150 provides an elastic deformation force so that the support 120 can move within the second range relative to the supporting surface. For example, the power adjusting device 150 further comprises an elastic adjusting device providing an elastic deformation force, the support 120 is connected to the elastic adjusting device, the elastic adjusting device provides the elastic deformation force to adjust the support force, and the support 120 can move within the second range under the action of the elastic deformation force of the elastic adjusting device.

[0070] In some embodiments, the elastic adjusting device is the auxiliary member 160. The auxiliary member 160 can be implemented as an elastic body such as a spring or a rubber sleeve, etc. connected at two ends to the support 120 and the sliding block 153, respectively. The elastic deformation force of the spring or the rubber sleeve, etc. can be utilized to provide a certain range of up and down movement space for the waist or the hip of the training object during walking in the process of implementing gait training by the training object using the follow-up rehabilitation training system, rather than directly transmitting the support force to the waist or the hip of the training object through rigid connection.

[0071] In addition, the sliding block 153 can also be provided with a sliding connection assembly 170. The sliding block 153 is slidably connected to the support 120 via the sliding connection assembly 170, so that the sliding block 153 can be connected to the support 120 in a relatively movable manner under the buffering action of the auxiliary member 160. In particular, the sliding connection assembly 170 can be implemented as comprising a sliding rod 171 fixed to the sliding block 153, and a sliding block 172 fixed to the support 120. The sliding block 172 is sleeved on the sliding rod 171 to slidably connect the support 120 to the sliding block 153.

[0072] Of course, in addition to using the elastic deformation force of the elastic adjustment device to achieve movement in the second range, the following embodiments can also be used. In some embodiments, the power adjustment device 150 further comprises a detection sensor for sensing the force acting on the support 120 or the movement of the support, and the control device controls the operation of the power device 151 to output a power source for driving the movement device to move the support in the second range according to the force or movement sensed by the detection sensor. Alternatively, the power adjustment device 150 further comprises an elastic adjustment device for providing an elastic deformation force and a detection sensor, the support 120 is connected to the elastic adjustment device, and the detection sensor is used to sense the force acting on the support 120 or the movement of the support 120. The control device controls the operation of the power device 151 to output a power source for driving the movement device to adjust the elastic deformation force of the elastic adjustment device, and to move the support 120 in the second range to adjust the support force.

[0073] In addition, with reference to the accompanying Figures 5 to 8 Another implementation of the auxiliary support weight loss system of the present application is described, wherein the auxiliary support weight loss system 200 comprises a main frame 210, a base 1000, a support 220, and an adjustment assembly, wherein the adjustment assembly comprises a power adjustment device 250, and the power adjustment device 250 comprises a power device 251, a control device, and a movement device. Compared with the auxiliary support weight loss system 100, the difference lies in the power adjustment device 250 and the related connection structure, which will be described in detail below with reference to the accompanying drawings.

[0074] The movement device is linked with the support 220, the control device controls the operation of the power device 251, and the power device 251 outputs a power source for driving the movement device to slide along the main frame 210 in the first range, and the movement device slides along the main frame 210 to drive the support 220 to slide along the main frame 210 to a set position. The power device 251 also outputs a power source for driving the movement device to move the support 220 in the second range, or the power adjustment device 150 provides an elastic deformation force so that the support 220 can move in the second range relative to the support surface.

[0075] In some embodiments, as Figures 4 to 7 The adjustment assembly further comprises a guide device 230 fixed to the main frame 210 and defining the trajectory of the vertical movement of the movement device and the support 220 along the main frame 210.

[0076] In some embodiments, the movement device can use an electric push rod transmission mechanism. Specifically, as Figures 4 to 7As shown, the movement device comprises a push rod 252 and a slide 253, and a power device 251 drives the push rod 252 to move up and down along the main frame 210 or the support direction of the main frame 210 or the direction in which the main frame 210 is located. The push rod 252 can be implemented as an electric push rod or an electro-hydraulic push rod. The power device 251 can be implemented as an electric motor. The up and down movement of the push rod 252 drives the slide 253 to move up and down along the main frame 210 or the support direction of the main frame 210 or the direction in which the main frame 210 is located, thereby driving the support 220 fixed on the slide 253 to also move along the main frame 210 in the first range.

[0077] The bottom end of the push rod 252 is fixed to the main frame 210, in particular to the lower beam 214 of the main frame 210. And preferably, as viewed from the front and rear direction (i.e. in the plane shown in Figure 5 And 6 The push rod 252 is located between the two guide rails of the guide device 230, in particular preferably in the middle of the two guide rails of the guide device 230, as viewed in the plane shown. The push rod 252 is arranged parallel to the columns 211, 212 of the main frame 210 and the guide rails of the guide device 230, i.e. the axis direction of the push rod 252 is consistent with the direction in which the slide 253 moves (i.e. the support direction) defined by the guide device 230.

[0078] Those skilled in the art will understand that the movement device can also be implemented as comprising other types of linear actuators, such as electric cylinders, pneumatic cylinders, hydraulic cylinders, etc.

[0079] The push rod 252 can be implemented to extend upward beyond the slide 253, in particular beyond the upper beam 213 of the main frame 210. And in this case, unlike the case of the auxiliary support weight reduction system 100, the push rod 252 is arranged outside the accommodation space defined between the columns 211, 212 and the beams 213, 214 of the main frame 110. Correspondingly, the slide 253 is provided with a connecting device 2531 to be connected to the push rod 252 via the connecting device 2531. The connecting device 2531 can be implemented as a pull rod, so that the extension or retraction of the push rod 252 pulls or pushes the slide 253 to slide along the support direction of the main frame.

[0080] In other embodiments, the push rod 252 can be implemented not to extend upward beyond the slide 253. Correspondingly, in this case, the slide 253 can be directly connected to the upper end of the push rod 252 without the connecting device 2531 implemented as a pull rod.

[0081] In particular, in this embodiment, the power adjusting device 250 provides an elastic deformation force so that the support 220 can move relative to the support surface in the second range. For example, the power adjusting device 250 further comprises an elastic adjusting device providing an elastic deformation force, the support 220 is connected to the elastic adjusting device, the elastic adjusting device provides the elastic deformation force to adjust the support force, and the support 220 can move in the second range under the action of the elastic deformation force of the elastic adjusting device. In some embodiments, the elastic adjusting device can be provided with an elastic body (such as a spring or a rubber sleeve, etc.) between the push rod 252 and the sliding block 253, and the elastic body is connected to the upper end of the push rod 241 and the upper end of the connecting device 2531 of the sliding block 253 respectively, so that the connection between the sliding block 253 and the push rod 252 has a buffering characteristic. The elastic deformation force of the spring or the rubber sleeve structure can be used to provide a certain range of up and down movement space for the waist or hip of the training object during walking in the process of implementing gait training for the training object by using the follow-up rehabilitation training system, instead of directly transmitting the support force to the waist or hip of the training object through rigid connection.

[0082] Of course, in addition to using the elastic deformation force of the elastic adjusting device to achieve the movement in the second range, the following embodiments can also be used. In some embodiments, the power adjusting device 250 further comprises a detection sensor for sensing the force acting on the support 220 or the movement of the support, and the control device controls the operation of the power device 251 to output the power source for driving the movement device to drive the support 220 to move in the second range according to the force or movement sensed by the detection sensor.

[0083] Alternatively, the power adjusting device 250 further comprises an elastic adjusting device providing an elastic deformation force and a detection sensor, the support is connected to the elastic adjusting device, the detection sensor is used to sense the force acting on the support 220 or the movement of the support, and the control device controls the operation of the power device 251 to output the power source for driving the movement device to adjust the elastic deformation force of the elastic adjusting device, drive the support 220 to move in the second range, and adjust the support force.

[0084] For example, a force sensor can also be directly arranged between the push rod 252 and the sliding block 253, for example, one end of the force sensor can be connected to the elastic body, and the other end can be connected to the upper end of the push rod 241 or the upper end of the connecting device 2531 of the sliding block 253, or the force sensor can be arranged at the bottom end of the push rod 252 between the push rod 252 and the lower beam 214 of the main frame 210 to directly sense the support force. Arranging the force sensor (such as a pressure sensor) between the push rod 252 and the lower beam 214 of the main frame 210 can cause interference problems caused by the weight and movement of the push rod 252.

[0085] By setting the elastic body between the push rod 252 and the sliding block 253, (1) in the system in which the auxiliary support force is not automatically controlled, the elastic body is used to realize the natural fluctuation of the waist of the training object in the rehabilitation training process; (2) in the system in which the auxiliary support force is automatically controlled, the fluctuation of the support of the waist of the training object in the rehabilitation training process can be realized through automatic control, at this time, the elastic body can also be set, mainly as a certain buffer, to avoid too large rigid impact in the walking process; of course, the elastic body can also not be set.

[0086] With reference to Figures 9 to 12 , the following describes still another embodiment of the auxiliary support weight reduction system according to the present application, wherein the auxiliary weight reduction support system 300 comprises a main frame 310, a base 1000, a support 320, and an adjusting assembly, wherein the adjusting assembly comprises a power adjusting device 350, and the power adjusting device 350 comprises a power device 351, a control device, and a movement device. Compared with the auxiliary support weight reduction systems 100 and 200, the difference lies in the power adjusting device 350 and the related connection structure, which will be specifically described below in combination with the drawings.

[0087] The movement device is linked with the support 320, the control device controls the operation of the power device 351, and the operation output power source of the power device 351 is used to drive the movement device to slide along the main frame 310 within a first range, and when the movement device slides along the main frame 310, the support 320 is driven to slide along the main frame 310 to a set position. The operation output power source of the power device 251 is also used to drive the movement device to drive the support 320 to move within a second range, or the power adjusting device 350 provides an elastic deformation force so that the support 320 can move within the second range relative to the support surface.

[0088] In some embodiments, as shown in Figures 9 to 12 , the adjusting assembly further comprises a guide device 330 fixed to the main frame 310 and defining the trajectory of the vertical movement of the movement device and the support 320 along the main frame 310.

[0089] In some embodiments, the motion device adopts a mechanical structure composed of a winding wheel and a flexible rope. The motion device comprises a wheel set 3521, a flexible rope 3522, a winding wheel 3523, and a sliding block 353. The wheel set 3521 can be fixed to the main frame 310, for example, the upper beam 313 of the main frame 310, and can change the extension direction of the flexible rope 3522. The power device 351 can be fixed to the main frame 310, for example, the lower beam 314 of the main frame 310. The flexible rope 3522 is wound on the wheel set 3521, one end of which is connected to the motion device, for example, connected to the sliding block 353 via the connecting device 3531, and the other end is connected to the winding wheel 3523 of the power device 351. The power device 351 can be implemented as an electric motor, which drives the winding wheel 3523 to rotate when rotating, and the rotation of the winding wheel 3523 shortens the flexible rope 3522 and drives the sliding block 353 to slide along the support direction of the main frame 310, thereby driving the support 320 fixed on the sliding block 353 to also slide along the main frame 310 within a first range.

[0090] Alternatively, an elastic member can also be provided between the flexible rope 3522 and the sliding block 353, and a sensor can also be provided to detect the size of the support force output by the adjustment device.

[0091] In particular, in this embodiment, the power adjustment device 350 provides an elastic deformation force so that the support 320 can move relative to the support surface within a second range. For example, the power adjustment device 350 further comprises an elastic adjustment device providing an elastic deformation force, the support 320 is connected to the elastic adjustment device, the elastic adjustment device provides an elastic deformation force to adjust the support force, and the support 320 can move within the second range under the action of the elastic deformation force of the elastic adjustment device. In some embodiments, an elastic body (such as a spring or a rubber sleeve, etc.) can be provided between the flexible rope 3522 and the sliding block 353, and the elastic body is connected to the connecting device 3531 of the flexible rope 3522 and the sliding block 353 at both ends, so that the connection between the sliding block 353 and the flexible rope 3522 has a buffering feature. In addition, the flexible rope 3522 itself can have elasticity to further provide the connection between the sliding block 353 and the flexible rope 3522 with a buffering feature. The elastic deformation force of the spring or the rubber sleeve and the like can also be used to provide a certain amplitude of up and down movement space for the waist or hip of the training object during walking in the process of implementing gait training for the training object using the follow-up rehabilitation training system, instead of directly transmitting the support force to the waist or hip of the training object through rigid connection.

[0092] Of course, in addition to using the elastic deformation force of the elastic adjustment device to realize the movement in the second range, the following embodiments can also be used. In some embodiments, the power adjustment device 350 further comprises a detection sensor for sensing the force acting on the support 320 or the movement of the support 320, and the control device controls the operation of the power device 351 to output the power source for driving the movement device to move the support 320 in the second range according to the force or movement sensed by the detection sensor.

[0093] Alternatively, the power adjustment device 350 further comprises an elastic adjustment device for providing an elastic deformation force and a detection sensor, the support 320 is connected to the elastic adjustment device, and the detection sensor is used to sense the force acting on the support 320 or the movement of the support 320. The control device controls the operation of the power device 351 to output the power source for driving the movement device to adjust the elastic deformation force of the elastic adjustment device, and to move the support 320 in the second range to adjust the support force.

[0094] For example, a force sensor can also be directly arranged between the flexible rope 3522 and the slider 353, for example, one end of the force sensor can be connected to the elastic body, and the other end can be connected to the flexible rope 3522 or the connecting device 3531 of the slider 353, or the force sensor can be arranged at the bottom end of the wheel set 3521 between the wheel set 3521 and the upper beam 313 of the main frame 310 to directly sense the support force. However, arranging the force sensor (such as a pressure sensor) between the wheel set 3521 and the upper beam 313 of the main frame 310 will cause interference problems caused by the weight and movement of the wheel set 3521.

[0095] By arranging the elastic body between the flexible rope 3522 and the slider 353, the following functions can be achieved: (1) In a system where the auxiliary support force is not automatically controlled, the elastic body is used to realize the natural fluctuation of the waist of the training object during the rehabilitation training process; (2) In a system where the auxiliary support force is automatically controlled, the fluctuation of the support of the waist of the training object during the rehabilitation training process can be realized through automatic control. At this time, the elastic body can also be arranged, mainly as a certain buffer, to avoid excessive rigid impact during walking. Of course, the elastic body can also not be arranged.

[0096] In some other embodiments, the adjustment device can have various modifications, and a connecting rod mechanism can also be used to realize the lifting and lowering of the movement device, and a gear and rack scheme can also be used to realize the lifting and lowering of the movement device.

The adjustment of the support force can be directly force feedback control adjustment by controlling the power unit, or can be through setting an elastic device between the movement device and the power adjustment device, controlling the deformation of the elastic device, and simultaneously detecting the deformation of the elastic device, to control the size of the support force outputted by the adjustment device.

[0098] The control assembly can be configured to control the movement of the power adjustment device according to user input.

[0099] The assisted support weight loss system can further comprise wireless and / or wired communication devices for receiving control signals / user input from external computing devices; and / or a keyboard and / or keys to receive user input.

[0100] The support force outputted by the adjustment device can be automatically adjusted, or manually controlled by the user. For automatic control adjustment, the required height and support force are calculated according to the body parameters (leg length and body weight) of the training subject, and then inputted into the control assembly, to obtain instructions for controlling the movement of the movement device through calculation, and to drive the power adjustment device, so as to drive the movement device to automatically ascend or descend, and to automatically adjust the support force. For manual control adjustment, only the input device (such as a switch, a button, a knob, etc.) and the power device of the power adjustment device are needed to realize manual adjustment.

[0101] In another aspect of the present application, a follow-up rehabilitation system is provided, which comprises any one of the assisted weight loss support systems 10A (such as any one of the assisted weight loss support systems 100, 200, 300) described above, and a base 1000 on which the main frame of the assisted weight loss support system 10A is fixedly installed. The base 1000 comprises casters 1200 installed on a follow-up frame 1100, and the main frame of the assisted weight loss support system is fixedly installed to the base 1000 via connecting legs. The follow-up frame 1100 can be implemented as an open rectangle, i.e. a rectangle having only three sides, in which a space is defined for the feet of the training subject to move in. The training subject can easily enter or exit from the opening. The casters 1200 can be implemented as universal wheels, and have braking devices, and can follow the movement of the training subject during rehabilitation training.

The lower limb rehabilitation training device is fixed to the support member of the assisted weight loss support system. The support force of the gait training device can be adjusted during rehabilitation training, to truly simulate the more realistic movement of the training subject, and to provide more realistic walking ground contact force.

As described above, the support force coarse adjustment mechanism can be realized by the sliding within the first range realized by the power adjustment device, and the support force fine adjustment mechanism can be realized by the movement of the support part within the second range relative to the support surface realized by the power adjustment device.
