Referring to FIG. 1 and FIG. 2, a rehabilitation robot 10 according to an embodiment is provided, which includes: an upper limb rehabilitation device and a lower limb rehabilitation device connected to the upper limb rehabilitation device. The upper limb rehabilitation device includes a head device 100, a shoulder width adjusting device 200, a right arm device 300, and a left arm device 400. The head device 100 is disposed on the shoulder width adjusting device 200. The right arm device 300 and the left arm device 400 are disposed at two sides of the shoulder width adjusting device 200, respectively. The shoulder width adjusting device 200 is used to adjust a shoulder width of the rehabilitation robot to fit a patient.

Referring to FIGS. 3 to 7, the shoulder width adjusting device 200 includes a back mechanism and a shoulder width adjusting mechanism. The back mechanism includes a first back plate 211. The right arm device 300 and the left arm device 400 are each movably connected to the first back plate 211. The shoulder width adjusting mechanism includes a shoulder width adjusting member. The shoulder width adjusting member is capable of driving the right arm device 300 or/and the left arm device 400 to move towards each other or away from each other, so as to adjust the shoulder width.

Referring to FIG. 3, the shoulder width adjusting device 200 further includes a shoulder mechanism, which includes a first shoulder plate 221 and a second shoulder plate 222. The first shoulder plate 221 and the second shoulder plate 222 are both movably connected to the first back plate 211. The right arm device 300 is disposed at the first shoulder plate 221, the left arm device 400 is disposed at the second shoulder plate 222. The shoulder width adjusting member drives the first shoulder plate 221 or/and the second shoulder plate 222 to move towards each other or away from each other, thus adjusting an interval between the right arm device 300 and the left arm device 400.

By driving the first shoulder plate 221 or/and the second shoulder plate 222 to move by the shoulder width adjusting member, the interval between the first shoulder plate 221 and the second shoulder plate 222 can be adjusted, thereby meeting the wear requirements of patients with different shoulder widths for subsequent rehabilitation.

As shown in FIGS. 6 and 7, the first back plate 211 is provided with a shoulder width adjusting guide rail 2111. The first shoulder plate 221 is provided with a first shoulder width slider 2211 mating the shoulder width adjusting guide rail 2111. The second shoulder plate 222 is provided with a second shoulder width slider 2221 mating the shoulder width adjusting guide rail 2111.

The shoulder width adjusting member drives the first shoulder width slider 2211 to move along the shoulder width adjusting guide rail 2111, the shoulder width adjusting member drives the second shoulder width slider 2221 to move along the shoulder width adjusting guide rail 2111, such that the first shoulder plate 221 and the second shoulder plate 222 move towards each other or away from each other. When the first shoulder plate 221 and the second shoulder plate 222 move towards each other, the shoulder width becomes smaller; when the first shoulder plate 221 and the second shoulder plate 222 move away from each other, the shoulder width is larger, such that the shoulder widths can be adjusted for the use of patients with different shoulder widths.

As shown in FIGS. 6 and 7, the first back plate 211 is provided with a shoulder width adjusting base 2112. The shoulder width adjusting member includes a shoulder width adjusting screw 231 rotatably disposed on the shoulder width adjusting base 2112. The shoulder width adjusting screw 231 is provided with a left-hand threaded section and a right-hand threaded section. The shoulder width adjusting mechanism further includes a first shoulder width adjusting nut 232 and a second shoulder width adjusting nut 233. The first shoulder width adjusting nut 232 is disposed on the first shoulder plate 221 and engaged with the left-hand threaded section, and the second shoulder width adjusting nut 233 is disposed on the second shoulder plate 222 and engaged with the right-hand threaded section.

When the shoulder width adjusting screw 231 rotates, the first shoulder width adjusting nut 232 and the second shoulder width adjusting nut 233 correspondingly move towards each other or away from each other due to the left-hand threaded section and the right-hand threaded section thereon, such that the shoulder plate 221 and the second shoulder plate 222 are driven to move towards each other or away from each other.

The shoulder width adjusting screw 231 may be adjusted manually, or may also be driven to rotate by a driving means. For example, as shown in FIGS. 5 and 6, the shoulder width adjusting mechanism further includes a shoulder width adjusting driver 234 for driving the shoulder width adjusting screw 231 to rotate. The shoulder width adjusting driver 234 is fixed to the first back plate 211. The shoulder width adjusting driver 234 may be a motor or other structure capable of implementing the driving. As shown in FIGS. 5 and 6, the shoulder width adjusting driver 234 transmits the drive torque to the shoulder width adjusting screw 231 by the mating of synchronous wheel and belt.

In an alternative embodiment, the shoulder width adjusting member includes a left-hand adjusting screw and a right-hand adjusting screw. The first shoulder width adjusting nut 232 is disposed at the first shoulder plate 221 and engaged with threads of the left-hand adjusting screw, and the second shoulder width adjusting nut 233 is disposed at the second shoulder plate 222 and engaged with threads of the right-hand adjusting screw. At this time, the left-hand adjusting screw and the right-hand adjusting screw may be rotated manually, and of course, two driving means may be provided to drive the left-hand adjusting screw and the right-hand adjusting screw, respectively.

As shown in FIG. 6, the shoulder width adjusting guide rail 2111 is provided with at least one shoulder width adjusting stopper 2113. The shoulder width adjusting stopper 2113 can restrict the amplitude of movement of the first shoulder width slider 2211 and the second shoulder width slider 2221 on the shoulder width adjusting guide rail 2111. Meanwhile, an accidental start or over-adjustment of the shoulder width adjusting driver 234 during use can be avoided, thus ensuring the safety of use. Further, the shoulder width adjusting stopper 2113 may be a shoulder width adjusting screw fixed to the shoulder width adjusting guide rail 2111.

Through the disposition of the shoulder width adjusting device 200, the rehabilitation robot 10 is capable of adjusting an interval between the right arm and the left arm thereof according to different shoulder widths conditions of patients, thereby allowing the rehabilitation robot to fit well with the patient, improving the rehabilitation therapy effect and improving the patient's therapy experience. In other words, the rehabilitation robot 10 is capable of meeting the use of rehabilitation of patients with different shoulder widths.

Referring to FIGS. 3 to 7, the head device 100 includes a helmet mechanism and a head adjusting mechanism. The helmet mechanism is disposed at the first back plate 211. The back mechanism further includes a second back plate 212 movably connected to the first back plate 211. The head adjusting mechanism is capable of driving the first back plate 211 to move on the second back plate 212, so as to adjust the position of the helmet mechanism relative to the second back plate. For example, the head adjusting mechanism is capable of driving the first back plate 211 to move upward and downward or left and right relative to the second back plate 212, however, the present disclosure is not limited thereto.

The head adjusting mechanism includes a head adjusting screw 121, a head adjusting nut 122, a head adjusting guide rail 123, a head adjusting slider 124, and a first head driver 125. Both of the head adjusting screw 121 and the head adjusting guide rail 123 are disposed on the second back plate 212. Both of the head adjusting nut 122 and the head adjusting slider 124 are disposed on the first back plate 211. The head adjusting screw 121 is threadedly engaged with the head adjusting nut 122. The head adjusting slider 124 is slidably disposed on the head adjusting guide rail 123.

The first head driver 125 can drive the head adjusting screw 121 to rotate, such that the head adjusting nut 122 moves in an axis direction of the head adjusting screw 121, thereby driving the first back plate 211 to move up and down. Since the helmet mechanism is disposed on the first back plate 211, the position of the helmet mechanism can be adjusted by the first back plate 211, and thus the function of adjusting a length of a neck or a height of the helmet mechanism can be implemented.

Of course, in an alternative embodiment, the first head driver 125 may drive the head adjusting screw 121 by a synchronous wheel and belt component, and the redundant description thereof will not be further described herein.

As shown in FIG. 5, the second back plate 212 is further provided with a mounting base 2122 for mounting the head adjusting guide rail 123. The mounting base 2122 is provided with an anti-waggling groove 1262 and an anti-waggling slider 1261. The anti-waggling slider 1261 can be selectively fixed into the anti-waggling groove 1262 and protrudes from the anti-waggling groove 1262. One side of the anti-waggling slider 1261 abuts against a sidewall of the anti-waggling groove 1262, the other side of the anti-waggling slider 1261 abuts against the head adjusting guide rail 123.

Since waggling may occur during mounting of the head adjusting guide rail 123 or during use, the anti-waggling slider 1261 can abut against the head adjusting guide rail 123, so as to prevent the waggling of the head adjusting guide rail 123, thus the stability is improved. When maintenance or the like is required, the anti-waggling slider 1261 can be removed from a current place, and moves and fixed to a proper position of the anti-waggling groove 1262, thus further improving the anti-waggling effect.

As shown in FIGS. 3 to 5, the helmet mechanism includes a helmet mounting stand 111, a helmet body 112, and a second head driver 113 for driving the helmet body 112 to rotate.

The helmet mounting stand 111 is fixed to the first back plate 211, the helmet body 112 is rotatably connected to the helmet mounting stand 111. The second head driver 113 is disposed on the helmet mounting stand 111 or the first back plate 211. The second head driver 113 can drive the helmet body 112 to move up and down on the helmet mounting stand 111, so as to achieve nodding of the helmet body 112. Of course, the second head driver 113 can also drive the helmet body 112 to waggle side to side on the helmet mounting stand 111, so as to achieve shaking of the helmet body 112.

The helmet mechanism further includes a helmet fixing ring 1121. The helmet body 112 is fixed to the helmet fixing ring 1121. The helmet fixing ring 1121 is shaped as a semicircular ring. Both ends of the helmet fixing ring 1121 are rotatably connected to the helmet mounting stand 111. As shown in FIG. 4, the helmet mounting stand 111 is substantially U-shaped. As shown in FIG. 3, a middle portion of the U-shaped helmet mounting stand 111 is provided with a connecting plate 1112 for fixing to the first backing plate 211.

In addition, as shown in FIG. 4, the helmet mechanism further includes a helmet strap 114 disposed on the helmet body 112 for easy wearing.

Referring FIGS. 4 and 5, the helmet mechanism further includes a helmet synchronous wheel 115, a head driving synchronous wheel 116 and a helmet driving synchronous belt (not shown). The helmet driving synchronous belt is wound on the helmet synchronous wheel and the head driving synchronous wheel, and the helmet body 112 is provided with a helmet mounting shaft rotatably connected to the helmet mounting stand 111. The helmet synchronous wheel is fixed to the helmet mounting shaft, and the helmet driving synchronous wheel is disposed on the second head driver 113.

Since the helmet driving synchronous belt may loosen after being used for a period of time, the helmet mounting stand 111 is further provided with a head tensioning roller 1111 for tensioning the helmet driving synchronous belt. The helmet mounting stand 111 is further provided with at least two head tensioning mounting holes 1113 for mounting the head tensioning roller 1111. When the head tensioning roller 1111 cannot achieve a predetermined tensioning effect, the head tensioning roller 1111 can be removed from one head tensioning mounting hole and mounted to another head tensioning mounting hole to further achieve a better tensioning effect. Further, the at least two head tensioning mounting holes are arranged at an interval.

As shown in FIG. 5, the first shoulder plate 221 is provided with a first shoulder arm mounting plate 2212 for connecting the right arm device 300. The second shoulder plate 222 is provided with a second shoulder arm mounting plate 2222 for connecting the left arm device 400.

Since the left arm device 400 and the right arm device 300 have a symmetrical configuration, only the right arm device 300 will be described as an example for ease of the illustration.

As shown in FIG. 8, the right arm device 300 includes an upper arm mechanism and a lower arm mechanism. The upper arm mechanism includes an upper arm plate 311 and an upper arm adjusting plate 312. The lower arm mechanism includes a lower arm plate 321, and one end of the lower arm plate 321 is rotatably connected to one end of the upper arm adjusting plate 312.

The upper arm adjusting plate 312 is movably connected to the upper arm plate 311 and capable of moving along the upper arm plate 311, thus adjusting length of the upper arm mechanism. Since different patients have different arm lengths, and when the patients use the right arm device 300 to perform the passive movement of the arm for rehabilitation, the wearing may be inconvenient or even impossible, which results in poor rehabilitation experience of the patient and failure of passive therapy. In the present embodiment, the upper arm adjusting plate 312 can move along the upper arm plate 311 to achieve the arm length adjustment of the upper arm mechanism, such that the wearing requirements of patients with different arm lengths are met, and the same right arm device 300 can be used for different patients to complete the wearing and the rehabilitation therapy, which greatly reduces the therapy cost compared to the conventional customized method.

Both of the left arm length and the right arm length of the rehabilitation robot 10 may be adjusted, and thereby meeting the uses of it fitted to patients with different arm lengths, allowing it to fit well with the patient.

As shown in FIG. 9, the upper arm plate 311 is provided with an upper arm sliding guide rail 3111 extending in a length direction of the upper arm plate 311. The upper arm adjusting plate 312 is provided with an upper arm slider 3121, which is slidably mates with the upper arm sliding guide rail 3111. The upper arm slider 3121 can move along the upper arm sliding guide rail 3111, thereby achieving the moving operation between upper arm adjusting plate 312 and the upper arm plate 311, and then the retractable length adjustment of the upper arm mechanism is realized.

The upper arm mechanism further includes an upper arm locking slider 313 slidably mating with the upper arm sliding guide rail 3111. The upper arm locking slider 313 is fixed on the upper arm adjusting plate 312. The upper arm locking slider 313 is provided with an upper arm locking threaded hole 315. The upper mechanism further includes an upper arm locking member 314 threadedly engaged with the upper arm locking threaded hole. When adjusting to a proper upper arm length, the position between the upper arm adjusting plate 312 and upper arm adjusting plate 312 is locked by manually rotating the upper arm locking member 314 to extend into the upper arm locking threaded hole and abut against the upper arm sliding guide rail 3111 closely.

Of course, in an alternative embodiment, the upper arm locking threaded hole can be disposed on the upper arm slider 3121. When the upper arm adjusting plate 312 is adjusted to a certain position, the upper arm locking member 314 is rotated to abut against the upper arm sliding guide rail 3111, and thus the technical effect of locking is achieved.

As shown in FIGS. 8 and 10, the right arm device 300 further includes an upper arm wiggling mechanism. The upper arm wiggling mechanism includes an upper arm wigging bracket 331, a first upper arm driver 332, and a second upper arm driver 333. The first upper arm driver 332 is used to drive the upper arm wigging bracket 331 to rotate, thus implementing the inward-outward wiggling motion of the upper arm mechanism. The upper arm plate 311 is rotatably disposed on the upper arm wigging bracket 331. The second upper arm driver 333 is disposed on the upper arm wigging bracket 331 and used to drive the upper arm plate 311 to rotate, thus implementing the forward-backward wiggling motion of the upper arm mechanism. A rotation axis of the upper arm wigging bracket 331 forms an angle with a rotation axis of the upper arm plate 311.

Further, the upper arm wigging bracket 331 is a bended plate provided with three strengthening ribs, so as to meet the requirements of the movement strength.

In assembly, the right arm device 300 is connected to the shoulder width adjusting device 200 by the first shoulder arm mounting plate 2212. The left arm device 400 is connected to the shoulder width adjusting device 200 by the second shoulder arm mounting plate 2222.

As shown in FIGS. 8 and 10, the upper arm wiggling mechanism further includes an arm connecting plate 334 fixed to the first shoulder arm mounting plate 2212. The upper arm wigging bracket 331 is rotatably disposed on the arm connecting plate 334. The upper arm wigging bracket 331 is further provided with a first upper arm arc-shaped strip 3311. The arm connecting plate 334 is further provided with a first upper arm stopper 3341. The upper arm wigging bracket 331 rotates and drives the first upper arm arc-shaped strip 3311 to rotate. The first upper arm stopper 3341 can stop the rotation of the first upper arm arc-shaped strip 3311 by abutting against an end of the arc-shaped strip 3311.

The right arm device 300 or the left arm device 400 can be used for assisting the patient to perform exercises of passive physical stretching out and drawing back or bending exercise. The robot may cause problems due to various unpredictable causes, such as excessive exercise, which may cause accidental injury or serious accident to the patient. Therefore, the first upper arm stopper 3341 and the first upper arm arc-shaped strip 3311 are provided. When the first upper arm driver 332 drives the upper arm wigging bracket 331 to rotate, the first upper arm arc-shaped strip 3311 is driven to rotate simultaneously. When the rotation reaches a certain amplitude or accidentally reaches to an unintended amplitude, the first upper arm stopper 3341 can perform a restricting function by abutting against the end of the first upper arm arc-shaped strip 3311. Due to the disposition of structure with an arc-shaped strip, a restricting function can be performed when the positive rotation proceeds as well as the negative rotation.

As shown in FIGS. 8 and 9, the upper arm wigging bracket 331 is provided with a second upper arm stopper 3312, the upper arm plate 311 is provided with a second upper arm arc-shaped strip 3112.

In an embodiment, the present disclosure provides a rehabilitation system. The rehabilitation system may include the rehabilitation robot 10. However, the present disclosure is not limited thereto.

For example, as shown in FIGS. 19 and 20, the rehabilitation system may further include a rehabilitation bed device 800 including a bed mechanism. The bed mechanism includes a bed base 811, a bed adjustable shelf 821 and a bed body 822. The bed base 811 is provided with a bed arc-shaped rail. The bed adjustable shelf 821 is capable of moving along the bed arc-shaped rail. The bed body 822 is movably connected to the bed base 811 and disposed on the bed adjustable shelf 821. The rehabilitation robot 10 is detachably disposed on the bed body 822.

As shown in FIGS. 19 to 21, when the bed adjustable shelf 821 moves on the bed arc-shaped rail, since it needs to move upwards, the cases of rolling over or falling off from the bed arc-shaped rail may occur. Therefore, the rehabilitation bed device 800 further includes an anti-fall mechanism. The anti-fall mechanism is disposed on the bed mechanism and used for preventing the bed adjustable shelf 821 from falling off the bed arc-shaped rail. Through the disposition of the anti-fall mechanism, and the anti-fall mechanism is disposed on the bed adjustable shelf 821, the anti-fall mechanism and the bed arc-shaped rail are movably connected therebetween, and thus the anti-fall mechanism is also slidably or scrollable engaged with the bed arc-shaped rail when the bed adjustable shelf 821 moves along the bed arc-shaped rail. In the meantime, the anti-fall mechanism and the bed adjustable shelf 821 are in a restricting collaboration therebetween, for avoiding falling-off of the bed adjustable shelf 821 from the bed arc-shaped rail, such that the overall operation is more stable and reliable, and the safety of use of it fitted to the patient is secured.

Therefore, when the patient is placed on the bed body 822, the disposition of the anti-fall mechanism prevents the bed adjustable shelf 821 from falling off from the bed arc-shaped rail, safety is improved, and thereby enabling the patient to follow the bed body 822 to move in the space, realizing auxiliary rehabilitation therapy for the patient and reducing the workload of the nursing worker.

As shown in FIG. 20, the bed base 811 is further provided with a first anti-fall rail 831 and a second anti-fall rail 832. The first anti-fall rail 831 and the second anti-fall rail 832 are provided to have an interval therebetween. The anti-fall mechanism includes the first anti-fall member and the second anti-fall member. The first anti-fall member is in a restricting engagement with the first anti-fall rail 831 and capable of moving along the first anti-fall rail 831. The second anti-fall member is in a restricting engagement with the second anti-fall rail 832 and capable of moving along the second anti-fall rail 832.

The anti-fall is realized by a means of the restricting engagement with each other between the first anti-fall rail 831 and the second anti-fall member, which may be embodied in many ways. For example, the first anti-fall rail 831 may be an anti-fall rail groove, the second anti-fall member may be an anti-fall rail engaged with the anti-fall rail groove, and an occlusal structure is provided between the anti-fall rail groove and anti-fall rail, thereby functioning as restricting and falling-off preventing. The second anti-fall rail 832 have the same operational principle as that of the second anti-fall member, and the redundant description thereof will not be further described herein.

As shown in FIG. 20, the first anti-fall rail 831 includes a first arc-shaped plate provided with a first arc-surface and a second arc-surface. The first anti-fall member includes at least two first roller 833. At least one first roller 833 is in rolling engagement with the first arc-surface. At least one first roller 833 is in rolling engagement with the second arc-surface. The second anti-fall rail 832 includes a second arc-shaped plate. The second arc-shaped plate is provided with a third arc-surface and a fourth arc-surface. The second anti-fall member includes at least two second roller 834. At least one second roller 834 is in rolling engagement with the third arc-surface. At least one second roller 834 is in rolling engagement with the fourth arc-surface.

As shown in FIG. 20, the first anti-fall rail 831 and the second anti-fall rail 832 are disposed at two sides of the bed arc-shaped rail, respectively, to making the operation of the bed mechanism more stable and reliable. Both of arc-shaped tracks of the first arc-shaped plate and the second arc-shaped plate are provided to be in correspondence with the bed arc-shaped rail. When the bed adjustable shelf 821 moves along the bed arc-shaped rail, the first roller 833 is capable of being in rolling engagement with two sides (the first and second arc-surfaces) of the first arc-shaped plate. Through the clamping function of the rolling engagement on both sides of the first roller 833, it is not only realized the engagement with the moving of the bed adjustable shelf 821 along the bed arc-shaped rail, but also realized the occlusal function for the first arc-shaped plate simultaneously, thereby realizing restriction and falling-off prevention. The second anti-fall rail 832 has the same principle of engagement as that of the second roller 834, and the redundant description thereof will not be further described herein.

In an alternative embodiment, as shown in FIGS. 20 and 23, in a case of meeting the requirements, one first roller 833 and one second roller 834 are arranged respectively. The first roller 833 is in rolling engagement with the arc-surface of the first arc-shaped plate towards ground side. The second roller 834 is in rolling engagement with the arc-surface of the second arc-shaped plate towards the ground side. Since the bed adjustable shelf 821 is relatively at a side of the first arc-shaped plate or the second arc-shaped plate far away from the ground, when the bed adjustable shelf 821 is adjusted, the first roller 833 and the second roller 834 can realize the restriction and falling-off prevention as well, and the redundant description thereof will not be further described herein.

As shown in FIGS. 21 and 23, the bed adjustable shelf 821 includes a bed adjustable plate 8211, a first side plate 8212 and a second side plate 8213. The first side plate 8212 and the second side plate 8213 are disposed at opposite sides of the bed adjustable plate 8211, respectively. Both of the first side plate 8212 and the second side plate 8213 are disposed at an angle. The first roller 833 is disposed on the first side plate 8212, the second roller 834 is disposed on the second side plate 8213.

As shown in FIG. 23, the first side plate 8212 and the second side plate 8213 is fixed on the opposite sides of the bed adjustable plate 8211 at a right angle, respectively. Both of plate sides of the first side plate 8212 and the second side plate 8213 towards the ground side are provided to have an arc-surface, the arc-surface is provided to be in correspondence with the arc-surface of the bed arc-shaped rail (or the first or second arc-shaped plate) for a better collaborate exercise, solving problems of interference that may occur.

As shown in FIG. 23, the first side plate 8212 is provided with four scrollable first rollers 833. The second side plate 8213 is provided with four scrollable second rollers 834. The first roller 833 may adopt two specifications for engaging with the first and second arc-surfaces of the first arc-shaped plate. The second roller 834 may also adopt two specifications for engaging with the third and fourth arc-surfaces of the second arc-shaped plate, and the redundant description thereof will not be further described herein.

As shown in FIGS. 23 and 24, the first side plate 8212 is further provided with a first ball seat 8214 and a first ball bearing 8215 convexly disposed on the first ball seat 8214.

The second ball bearing 8217 is in rolling engagement with the bed base 811.

When the bed adjustable shelf 821 moves by engaging with the bed arc-shaped rail, the derivation of movement may occur. For example, an offset toward the first side plate 8212 or second side plate 8213 may occur. At this time, the motion accuracy may be affected. Therefore, the first ball bearing 8215 and the second ball bearing 8217 are disposed on the first side plate 8212 and the second side plate 8213, respectively. When the bed adjustable shelf 821 offsets towards the first side plate 8212 side, the first ball bearing 8215 abuts against and is in rolling engagement with a side wall of the bed base 811. The reactive force may occur when abutting against, and thus the first ball bearing 8215 returns the bed adjustable shelf 821, so as to function as a certain adjustment, even if the bed adjustable shelf 821 is not returned. Since the first ball bearing 8215 is convexly disposed on the first ball seat 8214, the first side plate 8212 does not contact the bed base 811, such that friction affecting the movement of the bed mechanism is avoided, securing the normal operation. The second ball bearing 8217 and the second side plate 8213 have the same operational principle, and the redundant description thereof will not be further described herein.
