DETAILED DESCRIPTION

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] This embodiment discloses a movement assistive device for rehabilitation training of the elderly, referring to... Figure 1 , Figure 2 As shown, it includes two support frames 1, which are roughly parallel in structure, forming a space between the two support frames 1 for accommodating a human body. The front sides of the two supports are connected and fixed by connecting rods 8. Multiple sets of connecting rods 8 can be set as needed to maintain the structural stability of the two support frames 1.

[0032] The rear sides of both support frames 1 are open, allowing the user to enter between the two support frames 1 from the rear, with the user facing forward. Figure 2 As shown, the right side is the front side, and the left side is the back side.

[0033] Support legs 5 and rollers 6 are provided at the bottom of the support frame 1. The support legs 5 are fixedly connected to the bottom of the support frame 1 at the rear side. The rollers 6 are rotatably connected to the bottom of the support frame 1 at the front side.

[0034] The bottom of the support frame 1 is supported by the support foot 5 and the roller 6, which can maintain the stability of the motion assist device. By moving the rear support foot 5 slightly forward and using the front roller 6 as support, the entire motion assist device can be moved. The rolling friction can reduce the resistance to movement.

[0035] Reference Figure 2 As shown, the support frame 1 includes a first upright 101, a second upright 102, a first crossbar 103, and a second crossbar 104. The first upright 101 is located in front of the second upright 102, and the distance between the first upright 101 and the second upright 102 gradually increases downwards. Both the first upright 101 and the second upright 102 are slightly inclined, with the inclination of the first upright 101 being slightly greater than that of the second upright 102. The two ends of the first crossbar 103 and the second crossbar 104 are fixedly connected between the first upright 101 and the second upright 102, respectively. The first crossbar 103 and the second crossbar 104 are arranged in a parallel structure, roughly horizontal, and the crossbars also form a gripping position for the user, facilitating hand support or lifting of the motion assist device.

[0036] In addition, an auxiliary frame 2 is fixedly connected to the upper side of the support frame 1, and a support pad 3 is provided on the upper part of the auxiliary frame 2. A handle 4 is fixedly connected to the support foot 5 facing forward. The support pad 3 and the handle 4 can conveniently provide auxiliary support to the user.

[0037] like Figure 1 , 2 As shown, the height of the second crossbar 104 is approximately 80-85cm. When the user stands between the two support frames 1, both hands can grip the second crossbar 104 of the two support frames 1, allowing it to be used as a traditional step aid. The auxiliary frame 2 is higher, and the support pad 3 is installed on the upper side of the auxiliary frame 2. The support pad 3 supports the user's forearms. When in use, the user's upper arms hang downwards, and the arms can be placed on the upper part of the support pad 3, while the hands can grip the auxiliary handle 4. The arms can be used as support, making the exercise aid device more stable in supporting the user. The height of the support pad 3 is about 30cm higher than the second crossbar. The specific height can be set according to the user's different height, and multiple sizes are available to facilitate selection by users of different heights.

[0038] Example 2

[0039] This embodiment discloses a motor assistive device for rehabilitation training of the elderly, based on Embodiment 1, and further referring to... Figures 3-6 Please provide a detailed explanation.

[0040] Reference Figure 3 As shown, a mounting base 7 is fixedly connected to the lower front side of the support frame 1, that is, the lower end of the first upright 101 is fixedly connected to the mounting base 7. The roller 6 is provided with a linkage shaft 13, and the roller 6 is rotatably connected to the mounting base 7 through the linkage shaft 13.

[0041] During walking training, users sometimes need to maintain a roughly straight line to balance the force on both legs, allowing for smoother and more efficient training. When using this exercise assist device to walk forward, the rear supporting foot 5 is slightly advanced, with the two front rollers 6 providing primary rolling support. These rollers 6 are prone to shifting during forward rolling, causing their rotation to deviate and preventing the exercise assist device from maintaining a straight line, resulting in an arc-shaped trajectory. Furthermore, since the rollers 6 are located at the bottom of the exercise assist device, directly connecting them via a pivot would require a horizontal bar at the bottom between the two support frames 1, which would interfere with the user's foot lifting motion.

[0042] Reference Figure 3As shown, the mounting seat 7 is in a hollow structure, and the support frame 1 is provided with a tube cavity 9 extending upward and downward, and the connecting rod 8 is also provided with a tube cavity 9 extending horizontally, and the tube cavities 9 of the support frame 1 and the connecting rod 8 are communicated with each other, and the lower end of the tube cavity 9 in the support frame 1 is communicated with the inner cavity of the mounting seat 7. Specifically, the tube cavity 9 in the first vertical rod 101 is communicated with the tube cavity 9 in the connecting rod 8, forming a structure with three sides on the upper side, left and right sides, and the lower side being open.

[0043] In the embodiment, a linkage mechanism is arranged between the two linkage shafts 13, and the linkage mechanism is arranged in the tube cavity 9, so that the linkage of the two linkage shafts 13 can be realized. The outer diameters of the two rollers 6 are consistent, and the two rollers 6 are linked with each other, so that synchronous rotation can be realized, and then the movement auxiliary device can move forward.

[0044] Referring to Figure 4 As shown, the linkage mechanism includes a linkage rope 12, which is made of flexible material and has almost no elasticity, is used to transmit the length direction tension, and has good tensile strength performance. The linkage rope 12 is annular in structure with the first end adjacent to the second end, and at least part of the linkage rope 12 is arranged in the tube cavity 9, forming a state that two strands of the linkage rope 12 run in parallel in the tube cavity 9.

[0045] The two linkage shafts 13 are in a coaxial state, one side of the linkage rope 12 is wound around the outer periphery of one side of the linkage shaft 13, and the other side of the linkage rope 12 is wound around the outer periphery of the other side of the linkage shaft 13. The linkage rope 12 is wound 2-5 turns around the linkage shaft 13, and the winding directions of the linkage rope 12 around the two linkage shafts 13 are consistent.

[0046] Referring to Figure 4 As shown, when the movement auxiliary device moves forward, the roller 6 rolls forward with the ground, and the roller 6 drives the linkage shaft 13 to rotate. For the roller 6 on the right side, because the linkage rope 12 is wound around the outer periphery of the linkage shaft 13, there is a certain friction force, and when the linkage shaft 13 rotates, a first strand 1201 of the linkage rope 12 will form a unwinding action, and a second strand 1202 of the linkage rope 12 will form a winding action, so as to drive the linkage rope 12 to move. The opposite movement can also be formed between the roller 6 on the left side, the linkage shaft 13 and the linkage rope 12, the first strand 1201 of the linkage rope 12 forms a winding action, and the second strand 1202 of the linkage rope 12 forms a unwinding action, and the first strand 1201 and the second strand 1202 of the linkage rope 12 will form a mutual pulling and limiting action, so as to keep the two linkage shafts 13 rotating synchronously, and then the two rollers 6 can be kept rolling forward, avoiding the generation of too large bending curve.

[0047] Referring to Figure 3As shown, since the first upright 101 and the cavity 9 of the connecting rod 8 are approximately perpendicular, the cavity 9 is bent. Therefore, at the connection between the first upright 101 and the cavity 9 of the connecting rod 8, several guide wheels 10 and several guide wheels 11 can be provided. The guide wheels 10 and 11 can guide the two linkage ropes 12 separately, so that the linkage ropes 12 can smoothly bend in the cavity 9 and can reciprocate between the two linkage shafts 13 along the cavity 9.

[0048] Furthermore, to maintain the linkage rope 12 under tension, thereby creating a certain winding pressure between the linkage rope 12 and the linkage shaft 13, and thus ensuring sufficient friction between them to prevent slippage, anti-slip textures or an anti-slip coating can be provided on the outer circumferential surface of the linkage shaft 13. This further enhances friction between the linkage rope 12 and the linkage shaft 13, preventing slippage.

[0049] Reference Figure 5 , Figure 6 As shown, a tensioning mechanism 14 is provided in the middle of the crossbar, which keeps the linkage rope 12 taut. The tensioning mechanism 14 includes a housing 1401, which is fixedly connected to the crossbar and communicates with the cavity 9 inside the crossbar. The two linkage ropes 12 pass through the inner cavity of the housing 1401. A vertically oriented guide rail 1402 is provided in the inner cavity of the housing 1401, and two sliders 1403 are slidably connected to the guide rail 1402. Each slider 1403 is rotatably connected to a tensioning wheel 1404, which can move up and down along the guide rail 1402 following the sliders 1403.

[0050] Two connecting ropes 12 pass over tension pulleys 1404, respectively, on opposite sides of the pulleys 1404, i.e., above and below each pulley 1404. A spring 1405 is positioned between the two sliders 1403, with its upper and lower ends abutting against the sliders 1403 and elastically pushing them in opposite directions. Furthermore, two sets of limiting wheels 1406 are provided within the housing 1401, guiding the two connecting ropes.

[0051] When the linkage rope 12 passes through the tensioning mechanism 14, the two linkage ropes 12 pass over the upper and lower sides of the two tensioning wheels 1404 respectively. The first strand 1201 applies an upward force to the lower tensioning wheel 1404, and the second strand 1202 applies a downward force to the upper tensioning wheel 1404. The middle is elastically supported by the spring 1405. The elasticity of the spring 1405 provides tension to the linkage rope 12 and forms a certain elastic buffer space to avoid the linkage rope 12 breaking due to excessive force.

[0052] Embodiment Three

[0053] The embodiment discloses a motion assisting device for rehabilitation training of the elderly. The motion assisting device is based on the embodiments one or two, and is further described in detail with reference to Figure 7 、 Figure 8 .

[0054] As shown in Figure 7 , the linkage shaft 13 comprises a shaft sleeve 1301 and a shaft body 1302, and the shaft sleeve 1301 and the shaft body 1302 are arranged in a sleeved structure. The shaft sleeve 1301 penetrates through the mounting seat 7, and both ends of the shaft sleeve 1301 are rotationally connected to the mounting seat 7, and the middle section of the shaft sleeve 1301 is located in the inner cavity of the mounting seat 7. The shaft body 1302 is coaxially arranged in the inner wall of the shaft sleeve 1301, and both ends of the shaft body 1302 are rotationally connected to the inner wall of the shaft sleeve 1301 and are axially limited; one end of the shaft body 1302 extends out of the shaft sleeve 1301 and is fixedly connected to the roller 6, so that the shaft body 1302 can synchronously rotate with the roller 6.

[0055] As shown in Figure 7 、 Figure 8 , a plurality of through grooves 1303 are arranged on the outer wall of the middle section of the shaft sleeve 1301, the through grooves 1303 penetrate through the inner and outer walls of the shaft sleeve 1301, and the shaft sleeves 1301 are annularly and uniformly distributed. The movable block 1304 is arranged in the through groove 1303, the movable block 1304 can slide in the radial direction of the shaft sleeve 1301 in the through groove 1303, the movable block 1304 can partially extend out of the outer wall of the shaft sleeve 1301, and the movable block 1304 can partially extend into the inner wall of the shaft sleeve 1301. The linkage rope 12 is wound around the outer wall of the middle section of the shaft sleeve 1301, and the relative expansion and contraction of the movable block 1304 can slightly adjust the pressure of the linkage rope 12.

[0056] In order to limit the position of the linkage rope 12, the limiting block 15 is fixedly arranged on the upper side of the inner cavity of the mounting seat 7, the limiting block 15 is provided with a limiting hole 1501 penetrating through the upper and lower sides, the linkage rope 12 can smoothly pass through the limiting hole 1501, the position of the linkage rope 12 wound on the lower side is located on the outer wall of the middle section of the shaft sleeve 1301, i.e., the position of the movable block 1304, and the movable block 1304 can be wound in the inner wall.

[0057] The middle section of the shaft body 1302 is a linkage part 1305, the outer periphery of the linkage part 1305 is fixedly connected with linkage blocks 1306, and the linkage blocks 1306 are arranged in one-to-one correspondence with the movable blocks 1304. The linkage blocks 1306 are annularly and uniformly distributed, and the cross section of the linkage block 1306 is similar to a ratchet structure, one side of the linkage block 1306 is provided with a linkage surface one 1308, and the other side is provided with a linkage surface two 1307, wherein the linkage surface one 1308 is inclined and inclined towards the inner periphery of the shaft body 1302 in the direction of the movable block 1304.

[0058] Referring to Figure 8 When the roller 6 rolls towards the front side direction of the support frame 1, the roller 6 drives the shaft body 1302 to rotate clockwise, the shaft body 1302 rotates clockwise relative to the shaft sleeve 1301, the linkage surface one 1308 of the linkage block 1306 can be in mutual abutment with the movable block 1304, and through the inclined structure of the linkage surface one 1308, gradually moves to the inner side end position of the movable block 1304 one, the linkage surface one 1308 can abut and push the movable block 1304 to gradually protrude from the outer periphery of the shaft sleeve 1301. With the gradual protrusion of the movable block 1304, the contour of the linkage rope 12 originally around the middle section of the shaft sleeve 1301 is slightly larger, a certain pressure is generated between the movable block 1304 and the linkage rope 12, thereby the movable block 1304 and the linkage rope 12 can have stable friction, and smooth linkage between the shaft body 1302 and the shaft sleeve 1301 can be ensured.

[0059] In addition, a plurality of stop blocks 1309 are fixedly connected to the inner periphery of the middle section of the shaft sleeve 1301, the stop blocks 1309, the linkage blocks 1306 and the movable blocks 1304 are in one-to-one correspondence, the linkage block 1306 is located between the stop block 1309 and the movable block 1304, and the linkage surface two 1307 is formed on the side of the linkage block 1306 facing the stop block 1309, the linkage surface two 1307 is a plane, which can abut against the stop block 1309 to limit the relative rotation amplitude of the shaft sleeve 1301 and the shaft body 1302. The linkage block 1306 is blocked and limited by the movable block 1304 and the stop block 1309 on both sides in the rotation direction, so that the linkage block 1306 can only be adjusted within a small angle range, that is, only a small idle angle is formed between the shaft sleeve 1301 and the shaft body 1302, to avoid excessive rotation deviation of the rollers 6 on both sides.

[0060] Referring to Figure 8As shown, when the roller 6 rolls towards the rear side of the support frame 1, the roller 6 drives the shaft body 1302 to rotate counterclockwise, the shaft body 1302 rotates counterclockwise relative to the shaft sleeve 1301, the linkage surface two 1307 of the linkage block 1306 rotates towards the direction of the stop block 1309, until the linkage surface two 1307 abuts against the stop block 1309, the shaft sleeve 1301 and the shaft body 1302 will keep synchronous rotation. After the shaft body 1302 rotates, the abutting pressure of the linkage surface one 1308 of the linkage block 1306 and the movable block 1304 will be slightly relaxed, the movable block 1304 can slightly move inward, slightly preventing the loosening of the winding pressure of the linkage rope 12 on the middle section of the shaft sleeve 1301 and the outer side of the movable block 1304, and the linkage rope 12 can be slightly relaxed, so that the two linkage shafts 13 can produce small differential action, facilitating the adjustment of the rear movement of the entire movement auxiliary device and the adjustment of the direction and position of the movement auxiliary device.
