[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0039] See also Figure 1 An embodiment of the utility model provides a rehabilitation exercise device, which includes a frame 1 and a roller 2, a sling 3 and a weight-bearing assembly 8 arranged on the frame 1. The roller 2 is located at the bottom of the frame 1, and the sling 3 extends downward from the top of the frame 1 and is used to be fixed to the patient's shoulders. The other end of the sling 3 is connected to the weight-bearing assembly 8, and the weight-bearing assembly 8 is used to reduce the weight of the patient's legs.

[0040] In this embodiment, considering that the patient's legs need to move during the rehabilitation period but the leg muscles cannot fully support the patient's own weight, rollers 2 are provided at the bottom of the frame 1 to facilitate the patient's walking, and a sling 3 and a weight-bearing component 8 are provided on the frame 1, so that the sling 3 extends downward from the top of the frame 1 and is fixed to the patient's shoulders, and the weight-bearing component 8 is used to reduce the weight of the patient's legs, so that the patient's legs can receive better rehabilitation treatment. Therefore, the above technical solution can improve the rehabilitation treatment effect on the patient's legs.

[0041] In one embodiment of the utility model, the roller 2 includes two universal wheels 21 located at the front side and two follower wheels 22 located at the rear side, and the follower wheels 22 are casters or ball wheels. Such a configuration can facilitate the patient's walking and turning, and the follower wheels 22 can rotate in the direction of the universal wheels 21.

[0042] In one embodiment of the present invention, it also includes an armrest 5 disposed on the frame 1, and the armrest 5 is used to assist the patient in walking.

[0043] It should be noted here that during the patient's walking, the patient's hands do not need to be placed on the armrests 5, that is, the weight reduction provided to the patient's legs in most cases comes from the sling 3, and the armrests 5 are mainly provided to stabilize the patient's center of gravity, that is, during the patient's walking, the armrests 5 will not play a role in reducing the weight of the patient's legs.

[0044] In one embodiment of the present invention, a waist guard plate 51 which can move up and down is provided at a position of the armrest 5 close to the frame 1 , and the waist guard plate 51 is used to abut against the patient's waist.

[0045] In this embodiment, in order to further improve the rehabilitation treatment effect, it is possible to consider ensuring the posture stability of the patient during walking. Therefore, by setting a waist guard 51, it is possible to achieve contact with the patient's waist; further, it is considered to set a waist guard 51 that can be moved up and down, which can accommodate more patients of different heights, thereby increasing the range of people it is suitable for.

[0046] In one embodiment of the utility model, it also includes a hook 6 disposed on the frame 1, and the hook 6 is used to be fixed to the back of the patient;

[0047] When the patient is walking, the coat worn by the patient is fixed to the sling 3 and the hook 6 respectively, and when the patient turns, the hook 6 drives the frame 1 to turn.

[0048] In this embodiment, considering that the patient should try not to hold the handrail 5 with his hands when turning, a hook 6 is provided on the frame 1, so that the hook 6 can be used to hook the coat worn by the patient's upper body (of course, the sling 3 also hooks the coat to achieve the pulling of the patient), thereby relying on the hook 6 to drive the frame 1 to turn.

[0049] In one embodiment of the utility model, a fixed pulley block 7 is provided on the top of the frame 1, and the sling 3 is turned by the fixed pulley block 7. The weight-bearing component 8 and the patient's shoulders are respectively located on both sides of the fixed pulley block 7, so that better force can be applied to the sling 3.

[0050] In some embodiments, the suspension rope 3 may be a steel wire rope, and may also be made of other materials, which is not limited here.

[0051] like Figure 3 As shown, in one embodiment of the utility model, the fixed pulley assembly 7 includes a first fixed pulley 71 having two slideways and six second fixed pulleys 72 each having one slideway, wherein three second fixed pulleys 72 are symmetrically arranged with the other three second fixed pulleys 72;

[0052] For the three second fixed pulleys 72 on the same side, the three second fixed pulleys 72 are arranged at right angles;

[0053] For the six symmetrically arranged second fixed pulleys 72, two of the second fixed pulleys 72 are adjacent, and the two second fixed pulleys 72 respectively correspond to a slideway in the first fixed pulley 71, so that the two suspension ropes 3 passing through the two second fixed pulleys 72 and the first fixed pulley 71 are parallel, and the suspension rope 3 connecting the load-bearing component 8 and the first fixed pulley 71 is perpendicular to the horizontal plane.

[0054] In this embodiment, for the three second fixed pulleys 72 on the same side, the three second fixed pulleys 72 are arranged at right angles, so that it can be ensured that the force transmitted by the suspension rope 3 does not change. If there is an acute angle or an obtuse angle, the weight reduction will be inaccurate; the two suspension ropes 3 passing through the two second fixed pulleys 72 and the first fixed pulley 71 are parallel, so that the two suspension ropes 3 can be separated by using one first fixed pulley 71 without causing uneven force.

[0055] like Figure 2 As shown, in one embodiment of the utility model, the weight-bearing assembly 8 includes a weight-bearing block 81 and squeezing assemblies 82 located on both sides of the weight-bearing block 81, the sling 3 is connected to the weight-bearing block 81, and the squeezing assembly 82 is used to apply pressure to both sides of the weight-bearing block 81 to increase the weight reduction on the patient's legs.

[0056] In this embodiment, a weight block 81 and extrusion components 82 located on both sides of the weight block 81 are provided, so that the extrusion components 82 can be used to apply pressure to both sides of the weight block 81 to increase the weight reduction on the patient's legs, thereby achieving continuous weight reduction rather than discrete weight reduction (i.e., only relying on weight blocks of different weights), thereby achieving more accurate weight reduction for different target patients.

[0057] In one embodiment of the utility model, two linear slides 9 are provided at the bottom of the frame 1, and each extrusion assembly 82 includes a second linear motor 821 provided at the bottom of the frame 1, two movable connecting plates 822 sleeved on the linear slide 9, two springs 823 sleeved on the linear slide 9 and located between the two connecting plates 822, and an extrusion wheel 824 fixed to one connecting plate 822, the output shaft of the second linear motor 821 is fixed to the other connecting plate 822, the extrusion wheel 824 is used to abut against the two sides of the weight block 81, and the second linear motor 821 is used to drive the two connecting plates 822 to move left and right to change the pressure of the extrusion wheel 824 on the weight block 81.

[0058] In this embodiment, by providing a spring 823 and an extrusion wheel 824, a stable variable force can be achieved. By providing a second linear motor 821, the two connecting plates 822 can be driven to move left and right more conveniently to change the pressure of the extrusion wheel 824 on the weight block 81.

[0059] In one embodiment of the utility model, the weight-bearing assembly 8 further includes a second controller (not shown in the figure) disposed on the frame 1, and the second controller stores gait information obtained by pre-rehabilitation training of the target patient, and the gait information includes step frequency and foot pressure;

[0060] The second controller is electrically connected to the second linear motor 821, and is used to control the output shaft length of the second linear motor 821 based on the gait information of the target patient to change the pressure of the extrusion wheel 824 on the weight block 81, thereby keeping the weight borne by the target patient's legs unchanged.

[0061] In this embodiment, taking into account the different weights, walking frequencies, and pressures exerted by the soles of the feet on the ground each time different target patients walk, the utility model inventor creatively proposes that the gait information of different target patients can be collected first, so as to achieve "the right medicine for the right disease", that is, the output shaft length of the second linear motor 821 is controlled according to the gait information of the target patient to change the pressure of the extrusion wheel 824 on the weight block 81, thereby keeping the weight borne by the target patient's legs unchanged (i.e., constant force weight loss state), which can be more conducive to the rehabilitation treatment of the legs.

[0062] like Figure 1 and 3 As shown, in one embodiment of the utility model, the device further includes an adjustment component 4 disposed on the frame 1, and the adjustment component 4 is used to move the position of the sling 3 extending from the top of the frame 1 during the patient's walking process to keep the sling 3 in a vertically upward state relative to the patient's shoulders. In this way, the weight of the patient's leg can be kept unchanged (i.e., a constant force weight reduction state), which can be more conducive to the rehabilitation treatment of the leg.

[0063] It should be noted that if the sling 3 tilts while the patient is walking, the force on the patient's legs will change, that is, the weight of the leg weight reduction cannot remain unchanged, which is not conducive to the rehabilitation treatment of the patient's legs. However, by setting the adjustment component 4, constant force weight reduction on the patient's legs can be achieved.

[0064] Please continue reading Figure 3 In one embodiment of the utility model, the adjustment component 4 is respectively connected to two symmetrically arranged second fixed pulleys 72, and a strip hole 11 is provided on the top of the frame 1 running through the top and bottom. The sling 3 passes through the strip hole 11, and the adjustment component 4 is used to move the position of the sling 3 extending from the strip hole 11 during the patient's walking.

[0065] In this embodiment, a strip hole 11 passing through the top of the frame 1 is provided vertically, so that the adjustment component 4 can be used to move the position of the sling 3 extending from the strip hole 11 during the patient's walking, so as to keep the sling 3 in a vertically upward state relative to the patient's shoulders. In this way, the weight of the patient's legs can be kept unchanged (i.e., a constant-force weight reduction state), which can be more conducive to the rehabilitation treatment of the legs.

[0066] In one embodiment of the utility model, the adjustment component 4 includes a linear guide rail 41 and a first linear motor 42 arranged on the top of the frame 1, a slide 43 is arranged on the linear guide rail 41, a second fixed pulley 72 is fixed on the slide 43, the slide 43 is connected to the output shaft of the first linear motor 42, and the first linear motor 42 is used to drive the slide 43 to move forward and backward to move the position of the suspension rope 3 extending from the bar hole 11.

[0067] In this embodiment, a linear guide rail 41 and a first linear motor 42 are set, and a slide 43 is set on the linear guide rail 41. The slide 43 is connected to the output shaft of the first linear motor 42. In this way, the first linear motor 42 can be used to drive the slide 43 to move forward and backward to move the suspension rope 3 to extend from the bar hole 11. This method is simpler and faster.

[0068] In one embodiment of the utility model, the adjustment component 4 also includes a camera 44 and a first controller (not shown in the figure) arranged on the top of the frame 1, the camera 44 is used to capture the image of the patient's shoulder, the first controller is electrically connected to the camera 44 and the first linear motor 42, respectively, the first controller is used to determine the current position of the shoulder based on the image captured by the camera 44, and control the first linear motor 42 to drive the slide 43 to move based on the current position of the shoulder, so as to keep the sling 3 in a vertical upward state relative to the patient's shoulder.

[0069] In this embodiment, the first controller is used to extract features from the image captured by the camera 44 to determine the current position of the shoulder, and the current position exists in the first controller in the form of coordinates. Therefore, the first controller combines the coordinates with the current position coordinates of the output shaft of the first linear motor 42 to control the output distance of the output shaft next time, thereby keeping the sling 3 in a vertical upward position relative to the patient's shoulder.

[0070] In summary, by providing a weight block 81 and squeezing components 82 located on both sides of the weight block 81, the squeezing components 82 can be used to apply pressure to both sides of the weight block 81 to increase the weight loss on the patient's legs, thereby achieving continuous weight loss rather than discrete weight loss (i.e., relying solely on weight blocks of different weights), thereby achieving more accurate weight loss for different target patients. By providing an adjustment component 4 at the top of the frame 1, the adjustment component 3 can be used to move the position of the sling 3 extending from the top of the frame 1 during the patient's walking process to keep the sling 3 in a vertically upward state relative to the patient's shoulders, thereby keeping the weight of the patient's legs unchanged (i.e., a constant-force weight loss state), which can be more conducive to the rehabilitation treatment of the legs.

[0071] It should be noted that, in the present invention, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
