Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a rehabilitation training device for fracture patients with walking assistance function. Background Art

[0002] In life and work, injuries such as leg fractures are inevitable due to accidents. After a period of treatment, rehabilitation is still required to fully recover. Currently, there are many rehabilitation equipment for the legs, such as walking aids. Most of the existing walking aids are non-foldable designs, which are not convenient for storage. And when fracture patients use them, they need to repeatedly pick up the walking aid and move it to another position for training. However, fracture patients have weak leg strength, and there is no support for them during the process of picking up and moving the walking aid, so there is a risk of falling. Summary of the Invention

[0003] This section of the application is used to briefly introduce concepts, which will be described in detail in the following detailed implementation section. This section of the application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0004] To solve the technical problems mentioned in the above background art section, some embodiments of the present application provide a rehabilitation training device for fracture patients with walking assistance function, including a left walking assistance mechanism, a right walking assistance mechanism, a first connecting rod passing through the left walking assistance mechanism and the right walking assistance mechanism, and a second connecting rod fixedly arranged on the left walking assistance mechanism and the right walking assistance mechanism; the structure of the right walking assistance mechanism is the same as that of the left walking assistance mechanism; The left walking assistance mechanism includes a first moving component fixedly arranged on the second connecting rod, a first supporting component rotatably arranged on the first moving component, a second moving component, a second supporting component rotatably sleeved on the second moving component, and a third supporting component rotatably sleeved on the first moving component and the second moving component.

[0005] Specifically, the first moving component includes a first moving seat, a first rotating shaft rotatably arranged on the first moving seat, a second rotating shaft rotatably arranged on the first moving seat, first gears symmetrically fixed at both ends of the first rotating shaft, second gears symmetrically fixed at both ends of the second rotating shaft, a first chain symmetrically sleeved on the first gears and the second gears, and a first wheel fixed on the second rotating shaft; the structure of the second moving component is the same as that of the first moving component.

[0006] Specifically, the first support assembly includes a first connection block rotatably arranged on the first connecting rod, a first telescopic rod rotatably arranged on the first rotating shaft and having one end fixedly arranged on the first connection block, a first linkage device arranged on the first telescopic rod and the first rotating shaft, and a first spring having one end fixedly arranged on the first connection block and the other end fixedly arranged on the first telescopic rod.

[0007] Specifically, the second support assembly includes a second telescopic rod, a second linkage device arranged on the second telescopic rod and the second moving assembly; and a second spring sleeved on the second telescopic rod.

[0008] Specifically, the third support assembly includes a first support rod rotatably sleeved on the first connecting rod and rotatably sleeved on the second moving assembly, a second support rod rotatably sleeved on the first rotating shaft and rotatably sleeved on the other end of the second telescopic rod, a third telescopic rod having one end rotatably sleeved on the first connecting rod and the other end rotatably sleeved on one end of the second telescopic rod, and a fourth telescopic rod having one end rotatably sleeved on the second connecting rod and the other end rotatably sleeved on the second moving assembly.

[0009] Specifically, the first linkage device includes a first cavity fixedly arranged on the first telescopic rod, first sliding grooves symmetrically fixedly arranged on the first cavity, second sliding grooves symmetrically fixedly arranged on the first cavity, first sliding frames symmetrically sliding on the first sliding grooves and the second sliding grooves, a third gear rotatably arranged on the first cavity, fourth gears symmetrically fixedly arranged on both sides of the third gear, a fifth gear fixedly arranged on the first rotating shaft, a second chain sleeved on the third gear and the fifth gear, a first push rod fixedly arranged on the first telescopic rod and having the other end sleeved on the first sliding frame, and a first limiting device sliding on the first cavity.

[0010] Specifically, the first limiting device includes a third sliding groove fixedly arranged on the first cavity, a fourth sliding groove fixedly arranged on the first cavity, a first limiting frame sliding on the third sliding groove and the fourth sliding groove, a third spring having one end fixedly arranged on the first limiting frame and the other end fixedly arranged on the third sliding groove, and a fourth spring having one end fixedly arranged on the first limiting frame and the other end fixedly arranged on the fourth sliding groove.

[0011] Specifically, the second linkage device includes a second cavity fixedly arranged on the second telescopic rod, fifth sliding grooves symmetrically fixedly arranged on the second cavity, sixth sliding grooves symmetrically fixedly arranged on the second cavity, second sliding frames symmetrically sliding on the fifth sliding grooves and the sixth sliding grooves, a sixth gear rotatably arranged on the second cavity, seventh gears symmetrically fixedly arranged on both sides of the sixth gear, a third chain sleeved on the sixth gear and the second moving assembly, a second push rod fixedly arranged on the second telescopic rod and having the other end sleeved on the second sliding frame, and a second limiting device sliding on the second cavity.

[0012] Specifically, the second limiting device includes a seventh sliding groove fixedly provided on the second cavity, an eighth sliding groove fixedly provided on the second cavity, a second limiting frame slidably provided on the seventh sliding groove and the eighth sliding groove, a fifth spring with one end fixedly provided on the second limiting frame and the other end fixedly provided on the seventh sliding groove, and a sixth spring with one end fixedly provided on the second limiting frame and the other end fixedly provided on the eighth sliding groove.

[0013] The beneficial effects of the present invention are as follows: (1) The first support assembly and the second support assembly play a supporting role, and at the same time cooperate with the first moving assembly and the second moving assembly respectively. When the patient is training, as the patient presses with the arm, the first moving assembly and the second moving assembly can be alternately moved and locked, so that the walking aid can automatically move along with the patient's walking frequency. Compared with the existing walking aids, the patient does not need to lift and move the walking aid, which is more convenient to use, and also avoids the problem that the patient is prone to fall when losing support while moving the walking aid.

[0014] (2) When the patient uses it, hold the third telescopic rods on both sides with both hands. When the patient steps forward with the affected limb, pressure will be exerted on the support assemblies on both sides through the third telescopic rods, so that the first telescopic rod and the second telescopic rod are compressed, and the first push rod moves downward, thereby driving the first sliding frame to slide along the first sliding groove and the second sliding groove. Due to the provision of the guiding groove, the first sliding frame will slide in a counterclockwise direction on the first sliding groove and the second sliding groove, and will mesh with the fourth gear during the downward movement, driving the fourth gear to rotate. The fourth gear is coaxially and fixedly provided with the third gear, so the fourth gear will drive the third gear to rotate. The third gear will drive the fifth gear to rotate through the second chain. The fifth gear drives the first rotating shaft to rotate. The first rotating shaft will drive the first moving assembly to roll forward. At the same time, the second push rod moves downward, thereby driving the second sliding frame to slide along the fifth sliding groove and the sixth sliding groove. Due to the provision of the guiding groove, the second sliding frame will slide in a counterclockwise direction on the fifth sliding groove and the sixth sliding groove. However, different from the first sliding frame, the second sliding frame will first push the second limiting device to limit the second moving assembly during the downward movement, so that the second moving assembly cannot roll. When the first sliding frame and the second sliding frame move upward after passing through the bottom of the sliding groove, the first sliding frame will squeeze the first limiting device, so that the first limiting device limits the fourth gear and makes it unable to rotate, thereby making the first wheel unable to roll. At the same time, the second sliding frame will gradually disengage from the second limiting device. Then, during the upward movement of the second sliding frame on the fifth sliding groove and the sixth sliding groove, it will mesh with the seventh gear and drive the seventh gear to rotate. The seventh gear is coaxially and fixedly provided with the sixth gear, so the seventh gear will drive the sixth gear to rotate. The sixth gear will drive the second moving assembly to roll forward through the third chain. Description of the Drawings

[0022] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0023] Referring to Figures 1 - 15 As shown, a rehabilitation training device for fracture patients with a walking assistance function according to the present invention includes a left walking assistance mechanism 1, a right walking assistance mechanism 2, a first connecting rod 3 penetrating through the left walking assistance mechanism and the right walking assistance mechanism, and a second connecting rod 4 fixedly arranged on the left walking assistance mechanism and the right walking assistance mechanism; the structure of the right walking assistance mechanism is the same as that of the left walking assistance mechanism; the left walking assistance mechanism and the right walking assistance mechanism are respectively located on the left and right sides of the patient, and the patient is assisted to perform walking training through the walking assistance mechanisms on both sides; The left walking assistance mechanism includes a first moving component 11 fixedly arranged on the second connecting rod, a first supporting component 12 rotatably arranged on the first moving component, a second moving component 13, a second supporting component 14 rotatably sleeved on the second moving component, and a third supporting component 15 rotatably sleeved on the first moving component and the second moving component; the first moving component and the second moving component have the same structure; the first supporting component and the second supporting component play a supporting role, and at the same time cooperate with the first moving component and the second moving component respectively. When the patient is training, with the pressing of the patient's arm, the first moving component and the second moving component can be alternately moved and locked, so that the walking aid can automatically move along with the patient's walking frequency. Compared with the existing walking aid, the patient does not need to lift and move the walking aid, which is more convenient to use, and also avoids the problem that the patient is prone to fall when losing support during moving the walking aid.

[0024] Specifically, the first moving component includes a first moving seat 111, a first rotating shaft 112 rotatably arranged on the first moving seat, a second rotating shaft 113 rotatably arranged on the first moving seat, first gears 114 symmetrically fixed at both ends of the first rotating shaft, second gears 115 symmetrically fixed at both ends of the second rotating shaft, a first chain 116 symmetrically sleeved on the first gears and the second gears, and a first wheel 117 fixed on the second rotating shaft; the second moving component has the same structure as the first moving component; the first supporting component can drive the first rotating shaft to rotate, the first rotating shaft will drive the first gears on both sides to rotate, the first gears drive the second gears to rotate through the first chain, and the second gears drive the second rotating shaft to rotate, thereby driving the first wheel to rotate, so that the first moving component moves forward.

[0025] Specifically, the first supporting component includes a first connecting block 121 rotatably arranged on the first connecting rod, a first telescopic rod 122 rotatably arranged on the first rotating shaft and with one end fixedly arranged on the first connecting block, a first linkage device 123 arranged on the first telescopic rod and the first rotating shaft, and a first spring 124 with one end fixedly arranged on the first connecting block and the other end fixedly arranged on the first telescopic rod; the first linkage device is used to link the first telescopic rod and the first moving component. When the patient is training, due to the fracture of the patient's leg and insufficient supporting force, the upper limb and the walking aid need to be used for auxiliary support, that is, when the affected limb is stepped forward, pressure will be exerted on the walking aid. At this time, the first telescopic rod will be slightly compressed, and the first moving component will be driven to roll forward a certain distance through the first linkage component. Then the healthy limb is stepped forward. Since the healthy limb can provide support, the pressure of the patient's upper limb on the walking aid is reduced. At this time, the first telescopic rod will reset, but the first moving component will be limited in movement when the first linkage component resets, avoiding the first moving component from moving in the opposite direction.

[0026] Specifically, the second support assembly includes a second telescopic rod 141, a second linkage device 142 disposed on the second telescopic rod and the second moving assembly; a second spring 143 sleeved on the second telescopic rod; the second linkage device is used to link the second telescopic rod and the second moving assembly; when the patient is training, due to the fracture of the patient's leg and insufficient supporting force, the upper limb and the walking aid need to be used for auxiliary support. That is, when the affected limb is stepped forward, a pressure will be exerted on the walking aid. At this time, the first telescopic rod will be slightly compressed, and the first moving assembly will be driven by the first linkage assembly to roll forward for a certain distance. At this time, the second telescopic rod will also be slightly compressed, but the second linkage assembly will limit the second moving assembly at this time, so that the second moving assembly cannot roll. Then the healthy limb is stepped forward. Since the healthy limb can provide support, the pressure of the patient's upper limb on the walking aid is reduced. At this time, the first telescopic rod will reset, but the first linkage assembly will limit the movement of the first moving assembly when resetting, avoiding the first moving assembly from moving in the opposite direction. At this time, the second linkage assembly will release the limit on the second moving assembly, so that the second moving assembly can move forward. That is, when the patient steps forward the affected limb, the first moving assembly moves forward and the second moving assembly is stationary. Then when the healthy limb is moved, the first moving assembly is stationary and the second moving assembly moves forward, so that the walking aid moves with the patient during the patient's training. Compared with the existing walking aid, the patient does not need to lift and move the walking aid, which is more convenient to use and also avoids the problem that the patient is prone to fall when losing support when moving the walking aid.

[0027] Specifically, the third support assembly includes a first support rod 151 rotatably sleeved on the first link and rotatably sleeved on the second moving assembly, a second support rod 152 rotatably sleeved on the first rotating shaft and rotatably sleeved on the other end of the second telescopic rod, a third telescopic rod 153 with one end rotatably sleeved on the first link and the other end rotatably sleeved on one end of the second telescopic rod, and a fourth telescopic rod 154 with one end rotatably sleeved on the second link and the other end rotatably sleeved on the second moving assembly; the lengths of the first support rod and the second support rod are different, the first support rod and the second support rod are arranged in a cross shape, and a rotating shaft is provided at the intersection; when the first telescopic rod and the second telescopic rod are compressed and reset, they will drive the first support rod and the second support rod to rotate, and at the same time, the third telescopic rod and the fourth telescopic rod will also be stretched and contracted.

[0028] Specifically, the first linkage device includes a first cavity 1231 fixedly provided on the first telescopic rod, first sliding grooves 1232 symmetrically and fixedly provided on the first cavity, second sliding grooves 1233 symmetrically and fixedly provided on the first cavity, first sliding frames 1234 symmetrically sliding on the first and second sliding grooves, a third gear 1235 rotatably provided on the first cavity, fourth gears 1236 symmetrically and fixedly provided on both sides of the third gear, a fifth gear 1237 fixedly provided on the first rotating shaft, a second chain 1238 sleeved on the third gear and the fifth gear, a first push rod 1239 fixedly provided on the first telescopic rod and sleeved on the first sliding frame at the other end, and a first limiting device 125 sliding on the first cavity; the first and second sliding grooves are hexagonal sliding grooves, and the first and second sliding grooves are provided with guiding grooves, and the guiding grooves are arranged in a dislocation manner with the first and second sliding grooves; the first sliding frames slide on the first and second sliding grooves, and the surface of the first sliding frame in contact with the fourth gear is provided with teeth; the top of the first sliding frame slides at the bottom of the first push rod. When the first telescopic rod is compressed, that is, the first push rod moves downward, and then drives the first sliding frame to slide along the first and second sliding grooves. Due to the provision of the guiding grooves, the first sliding frame will slide in a counterclockwise direction on the first and second sliding grooves, and mesh with the fourth gear during the downward movement, driving the fourth gear to rotate. The fourth gear is coaxially and fixedly arranged with the third gear, so the fourth gear will drive the third gear to rotate. The third gear will drive the fifth gear to rotate through the second chain, and the fifth gear drives the first rotating shaft to rotate. The first rotating shaft will drive the first moving assembly to roll forward. When the first sliding frame slides to near the bottom, it will gradually disengage from the fourth gear. Then, during the upward movement of the first sliding frame on the first and second sliding grooves, the first sliding frame will squeeze the first limiting device, so that the first limiting device limits the fourth gear and makes it unable to rotate, and further makes the first wheel unable to roll.

[0029] Specifically, the first limiting device includes a third chute 1251 fixedly arranged on the first cavity, a fourth chute 1252 fixedly arranged on the first cavity, a first limiting frame 1253 slidably arranged on the third chute and the fourth chute, a third spring 1254 with one end fixedly arranged on the first limiting frame and the other end fixedly arranged on the third chute, and a fourth spring 1255 with one end fixedly arranged on the first limiting frame and the other end fixedly arranged on the fourth chute; the lower end surface of the part of the first limiting frame overlapping with the first chute and the second chute is provided with an inclined surface to facilitate the first sliding frame to push the first limiting frame; when the first sliding frame enters the upward moving part of the first chute and the second chute, it will squeeze the first limiting frame to move, the fourth spring is squeezed, and after the first limiting frame moves, it will engage with the fourth gear. Since the first limiting frame is limited by the third chute and the fourth chute and cannot rotate, the fourth gear will be stuck and cannot rotate, that is, the first wheel cannot roll. When the first sliding frame slides to the highest point of the first chute and the second chute, that is, when it enters the guiding groove, the first sliding frame and the first limiting frame are separated from contact, the fourth spring pushes the first limiting frame to reset, and the first limiting frame disengages from the fourth gear to release the limit.

[0030] Specifically, the second linkage device includes a second cavity 1421 fixedly arranged on the second telescopic rod, fifth sliding grooves 1422 symmetrically fixedly arranged on the second cavity, sixth sliding grooves 1423 symmetrically fixedly arranged on the second cavity, second sliding frames 1424 symmetrically slidably arranged on the fifth and sixth sliding grooves, a sixth gear 1425 rotatably arranged on the second cavity, seventh gears 1426 symmetrically fixedly arranged on both sides of the sixth gear, a third chain 1427 sleeved on the sixth gear and the second moving assembly, a second push rod 1428 fixedly arranged on the second telescopic rod and with the other end sleeved on the second sliding frame, and a second limiting device 144 slidably arranged on the second cavity; the fifth and sixth sliding grooves are hexagonal sliding grooves, and the fifth and sixth sliding grooves are provided with guide grooves, and the guide grooves are arranged in a staggered manner with the first and second sliding grooves, and the positions of the guide grooves on the fifth and sixth sliding grooves are different from the positions of the guide grooves on the first and second sliding grooves; the second sliding frames are slidably arranged on the fifth and sixth sliding grooves, and the surface of the second sliding frame in contact with the seventh gear is provided with teeth; the top of the second sliding frame is slidably arranged at the bottom of the second push rod. When the second telescopic rod is compressed, that is, the second push rod moves downward, and then drives the second sliding frame to slide along the fifth and sixth sliding grooves. Due to the arrangement of the guide grooves, the second sliding frame will slide in a counterclockwise direction on the fifth and sixth sliding grooves. However, different from the first sliding frame, the second sliding frame will first push the second limiting device to limit the second moving assembly during the downward movement, so that the second moving assembly cannot roll. When the second sliding frame slides to near the bottom, it will gradually disengage from the second limiting device. Then, when the second sliding frame moves upward on the fifth and sixth sliding grooves, it will engage with the seventh gear and drive the seventh gear to rotate. The seventh gear is coaxially fixedly arranged with the sixth gear, so the seventh gear will drive the sixth gear to rotate, and the sixth gear will drive the second moving assembly to roll forward through the third chain.

[0031] Specifically, the second limiting device includes a seventh slide 1441 fixed on the second cavity, an eighth slide 1442 fixed on the second cavity, a second limiting frame 1443 slidably arranged on the seventh slide and the eighth slide, a fifth spring 1444 fixed at one end on the second limiting frame and fixed at the other end on the seventh slide, and a sixth spring 1445 fixed at one end on the second limiting frame and fixed at the other end on the eighth slide; the upper end surface of the portion where the second limiting frame overlaps with the fifth slide and the sixth slide is provided with an inclined surface, and since the bottom of the second sliding frame contacts the second limiting frame first when sliding, The inclined surface is arranged to facilitate the second sliding frame to push the second limiting frame; when the second sliding frame enters the downward moving part of the fifth slide groove and the sixth slide groove, it will squeeze the second limiting frame to move, the fifth spring is squeezed, and the second limiting frame will mesh with the seventh gear after moving. Since the second limiting frame is limited by the seventh slide groove and the eighth slide groove and cannot rotate, it will jam the seventh gear, and the seventh gear cannot rotate, that is, the second moving assembly cannot roll. When the second sliding frame slides to the lowest point of the fifth slide groove and the sixth slide groove, the second sliding frame is disengaged from the second limiting frame, and the fifth spring pushes the second limiting frame to reset, and the second limiting frame is disengaged from the seventh gear, and the limit is released.

[0032] The above descriptions are merely some preferred embodiments of the present disclosure and illustrate the underlying technical principles. Those skilled in the art should understand that the scope of the invention encompassed by the embodiments of the present disclosure is not limited to technical solutions formed by specific combinations of the aforementioned technical features.
