The structure of the displacement device of the present invention will be described in detail in conjunction with the accompanying drawings.

[0051] Embodiment 1

[0052] Figure 1 Schematic diagram of the three-dimensional structure of the displacement device of this embodiment is shown. Figure 1 In this embodiment, the shifting device includes a base 1, a support frame 2, a shifting adjustment mechanism 3, a first connecting mechanism 4, a second connecting mechanism 5 and a mounting mechanism 6.

[0053] See also Figure 1 In this embodiment, a moving wheel 11 is installed at the bottom of the base 1, so that the entire displacement device can be easily moved. The moving wheel 11 can be a universal wheel with a locking device, so that the displacement device can be easily moved to a specified position and fixed by the locking device. Of course, in some embodiments, the base 1 may not be provided with a moving wheel 11, but a variety of methods such as a quick clamp can be used to stabilize the base 1, wherein the quick clamp is designed according to the mechanical principle of the double rocker structure in the planar four-bar mechanism, and uses the dead point clamping in mechanical mechanics.

[0054] See also Figure 1, in this embodiment, the support frame 2 is installed on one side of the base 1, and the length of the support frame 2 is adjustable. The support frame 2 includes a first support rod section 21 and a second support rod section 22; the lower end of the first support rod section 21 is fixedly connected to the base 1, and the lower end of the second support rod section 22 is inserted into the upper end of the first support rod section 21 and locked by a locking knob (not shown in the figure). Specifically, by loosening the locking knob, the length of the second support rod section 22 inserted into the first support rod section 21 can be adjusted to control the length of the support frame 2, and after adjusting to the appropriate length, it is locked by the locking knob. It can be understood that in other embodiments, the relative position adjustment of the first support rod section 21 and the second support rod section 22 of the support frame 2 can also be realized through a lead screw-nut transmission mechanism or other existing adjustment mechanisms to achieve the purpose of adjusting the length of the support frame 2.

[0055] Please refer to Figure 1 , in this embodiment, an armrest 23 is further provided on the support frame 2, which is convenient for holding during rehabilitation training. The armrest 23 can be arranged on the second support rod section 22. Of course, the armrest 23 can also be Figure 4 arranged on the first support rod section 21 as shown.

[0056] Please refer to Figure 1 , in this embodiment, on one side of the support frame 2 facing the displacement adjustment mechanism 3, a mounting seat 24 for mounting the displacement adjustment mechanism 3 is provided, and the height of the mounting seat 24 on the support frame 2 is adjustable, so that the mounting position of the displacement adjustment mechanism 3 on the support frame 2 can be adjusted. On one side of the first support rod section 21 of the support frame 2 facing the displacement adjustment mechanism 3, a plurality of first threaded holes are provided, and the plurality of first threaded holes are arranged along the length direction of the first support rod section 21. A second threaded hole corresponding to the first threaded hole is provided on the mounting seat 24, and the mounting seat 24 can be installed at a suitable position on the first support rod section 21 through bolts.

[0057] Please refer to Figure 1 , in this embodiment, the length of the first support rod section 21 is also adjustable, including a bottom fixed section and a top movable section. The bottom fixed section and the top movable section can adopt a connection method similar to that of the first support rod section 21 and the second support rod section 22, so that the mounting seat 24 can be fixedly installed on the top movable section of the first support rod section 21, and the height of the displacement adjustment mechanism 3 can be directly adjusted by adjusting the length of the top movable section extending out of the bottom fixed section.

[0058] Please refer to Figure 1, in this embodiment, the displacement adjustment mechanism 3 is designed in a parallelogram structure, including a first upper connecting rod 31, a first lower connecting rod 32, and a first electric push rod 33; the first upper connecting rod 31 is parallel to the first lower connecting rod 32, and the first upper connecting rod 31 is located above the first lower connecting rod 32; one end of the first upper connecting rod 31 and the first lower connecting rod 32 is rotatably connected to the support frame 2, and the other end of the first upper connecting rod 31 and the first lower connecting rod 32 is rotatably connected to one end of the first connecting mechanism 4; the push rod end 331 of the first electric push rod 33 is rotatably connected to the first upper connecting rod 31 (or the first lower connecting rod 32), and the tail end 332 of the first electric push rod 33 is rotatably connected to the support frame 2. By adjusting the overall lifting of the displacement adjustment mechanism 3 through the first electric push rod 33, the displacement of the installation mechanism 6 can be driven (including horizontal translation and vertical lifting), and a large-range displacement of the limb rehabilitation assistive device 7 installed thereon can be achieved through a small displacement of the push rod. Of course, in other embodiments, the tail end 332 of the first electric push rod 33 is rotatably connected to the first upper connecting rod 31 (or the first lower connecting rod 32), and the push rod end 331 of the first electric push rod 33 is rotatably connected to the support frame 2.

[0059] Specifically, as Figure 1 shown, the push rod end of the first electric push rod 33 is rotatably connected to the rod body of the first upper connecting rod 31 (or the first lower connecting rod 32) close to the support frame 2. It can be understood that in some embodiments, the push rod end of the first electric push rod 33 is rotatably connected to other positions of the first upper connecting rod 31, such as being connected in the middle.

[0060] Specifically, as Figure 1 shown, the first upper connecting rod 31 and the first lower connecting rod 32 each include two; one end of the two first upper connecting rods 31 is rotatably connected to the upper end of the mounting seat 24, and the other end of the two first upper connecting rods 31 is rotatably connected to the upper part of one end of the first connecting mechanism 4; one end of the two first lower connecting rods 32 is rotatably connected to the upper end of the mounting seat 24, and the other end of the two first lower connecting rods 32 is rotatably connected to the lower part of one end of the first connecting mechanism 4; a rotational connection is formed between the rod bodies of the two first upper connecting rods 31 close to the support frame 2 and the push rod end 331 of the first electric push rod 33 through a rotating shaft, and the tail end 332 of the first electric push rod 33 is rotatably connected to the lower end of the mounting seat 24.

[0061] As Figure 1As shown, in this embodiment, the first connecting mechanism 4 is a double-plate structure arranged symmetrically (of course, it can also be a double-rod structure). One end of the first connecting mechanism 4 is connected to the displacement adjustment mechanism 3, and the other end of the first connecting mechanism 4 is connected to one end of the second connecting mechanism 5.

[0062] As Figure 1 shown, in this embodiment, the second connecting mechanism 5 includes a second upper connecting rod 51a, a second lower connecting rod 51b, a fixing part 52, and a second electric push rod 53. One end of the second upper connecting rod 51a and the second lower connecting rod 51b is rotatably connected to the end of the first connecting mechanism 4 that is not connected to the displacement adjustment mechanism 3. The other ends of the second upper connecting rod 51a and the second lower connecting rod 51b are respectively rotatably connected to the upper and lower ends of the fixing part 52. The fixing part 52 is fixedly connected to the mounting mechanism 6. The push rod end of the second electric push rod 53 is rotatably connected to the second upper connecting rod 51a (or the second lower connecting rod 51b), and the tail end of the second electric push rod 53 is rotatably connected to the first connecting mechanism 4. By the second electric push rod 53, the tilt angle of the mounting mechanism 6 can be adjusted, so as to realize the adjustment of the tilt angle of the limb rehabilitation assistive device 7 mounted on the mounting mechanism 6 to meet the movement training needs of different people. Of course, in other embodiments, the tail end of the second electric push rod 53 is rotatably connected to the second upper connecting rod 51a (or the second lower connecting rod 51b), and the push rod end of the second electric push rod 53 is rotatably connected to the first connecting mechanism 4.

[0063] Specifically, as Figure 1 shown, the push rod end of the second electric push rod 53 is rotatably connected to the rod body of the second upper connecting rod 51a (or the second lower connecting rod 51b) near the fixing part 52. It can be understood that in some embodiments, the push rod end of the second electric push rod 53 is rotatably connected to other positions of the second upper connecting rod 51a.

[0064] In this embodiment, there are two second upper connecting rods 51a and two second lower connecting rods 51b respectively. The two second upper connecting rods 51a are symmetrically arranged on both sides of the first connecting mechanism 4, and the two second lower connecting rods 51b are also symmetrically arranged on both sides of the first connecting mechanism 4, and the second upper connecting rod 51a is located above the second lower connecting rod 51b.

[0065] As Figure 1 shown, in this embodiment, the mounting mechanism 6 adopts a U-shaped gripper. The base 71 of the limb rehabilitation assistive device 7 is inserted into the U-shaped gripper, and the U-shaped gripper realizes the clamping and fixing of the base 71 of the limb rehabilitation assistive device 7 under the action of the internal elastic member (the clamping and fixing method can refer to 6).

[0066] Of course, in some embodiments, the mounting mechanism 6 may also adopt, for example, Figure 3 the bolt mounting mechanism 6 as shown, and can be fixedly connected to the base 71 of the limb rehabilitation assistive device 7 by means of bolt connection.

[0067] Of course, the mounting mechanism 6 may also adopt a structure similar to Figure 8 the magnetic chuck shown, Figure 9 the rectangular tubular mounting frame shown, or other mechanisms such as a square box tray that are convenient for connecting and fixing to the base 71 of the limb rehabilitation assistive device 7.

[0068] It should be noted that the limb rehabilitation assistive device 7 described in this embodiment can be, for example, a limb rehabilitation assistive device 7 with joint angle training requirements such as a crank-slider type, a crank-rocker type, a swing guide rod type, and a crank-block type. Using the displacement device of this embodiment, it is possible to keep the limb rehabilitation assistive device 7 in a horizontal state during the displacement process, which is stable and safe. Using the displacement device of this embodiment, by horizontally moving the limb rehabilitation assistive device 7, it is possible to ensure that the basic angles required for joint training remain unchanged.

[0069] Embodiment 2

[0070] As Figure 5 shown, this embodiment introduces another displacement device. The displacement device also includes a base 1, a support frame 2, a displacement adjustment mechanism 3, a first connection mechanism 4, a second connection mechanism 5, and a mounting mechanism 6. Compared with the displacement device of Embodiment 1, the difference is that the structure of the second connection mechanism 5 is different, and the other structures are basically the same, so they will not be described repeatedly.

[0071] Please refer to Figure 5 , in this embodiment, the second connection mechanism 5 includes a second connecting rod 51 and a second electric push rod 53; the second connecting rod 51 adopts a spoon-shaped structure. One end of the second connecting rod 51 is rotatably connected to the end of the first connection mechanism 4 that is not connected to the displacement adjustment mechanism 3, and the other end of the second connecting rod 51 is fixedly connected to the mounting mechanism 6; the push rod end / tail end of the second electric push rod 53 is rotatably connected to the middle of the first connection mechanism 4, and the tail end / push rod end of the second electric push rod 53 is rotatably connected to the middle of the second connecting rod 51. By the second electric push rod 53, the tilt angle of the mounting mechanism 6 can be adjusted, so as to adjust the tilt angle of the limb rehabilitation assistive device 7 mounted on the mounting mechanism 6 to meet the movement training needs of different people.

[0072] Please refer to Figure 5 , in this embodiment, the mounting mechanism 6 adopts a U-shaped gripper. As Figure 6As shown, insert the base 71 of the limb rehabilitation assistive device 7 into the U-shaped gripper. The U-shaped gripper clamps and fixes the base 71 of the limb rehabilitation assistive device 7 under the action of the internal elastic member.

[0073] Of course, the installation mechanism 6 in this embodiment can also be similar to Figure 3 the bolt installation mechanism 6 shown. The bolt installation mechanism 6 can be fixedly connected to the base 71 of the limb rehabilitation assistive device 7 by means of bolt connection.

[0074] Of course, the installation mechanism 6 in this embodiment can also be similar to Figure 8 the magnetic chuck shown, Figure 9 the rectangular tubular installation frame shown, or other mechanisms such as a square box tray that are convenient for connecting and fixing to the base 71 of the limb rehabilitation assistive device 7.

[0075] It should be noted that the limb rehabilitation assistive device 7 described in this embodiment can be, for example, a limb rehabilitation assistive device 7 with joint angle training requirements such as a crank-slider type, a crank-rocker type, a swing guide rod type, and a crank-block type. Using the displacement device of this embodiment, the limb rehabilitation assistive device 7 can be kept in a horizontal state during the displacement process, which is stable and safe. Using the displacement device of this embodiment, by horizontally moving the limb rehabilitation assistive device 7, the basic angles required for joint training can be ensured to remain unchanged.

[0076] Embodiment III

[0077] As Figure 7 shown, this embodiment introduces a third displacement device. The displacement device also includes a base 1, a support frame 2, a displacement adjustment mechanism 3, a first connection mechanism 4, a second connection mechanism 5, and an installation mechanism 6. Compared with the displacement device of Embodiment I, the difference is that the structure of the second connection mechanism 5 is different, and the other structures are basically the same, so they will not be described repeatedly.

[0078] Please refer to Figure 7 , in this embodiment, the second connection mechanism 5 is a pair of connecting rods symmetrically arranged on both sides of the first connection mechanism 4. One end of the second connection mechanism 5 is fixedly connected to the end of the first connection mechanism 4 that is not connected to the displacement adjustment mechanism 3, and the other end of the second connection mechanism 5 is fixedly connected to the installation mechanism 6.

[0079] Please refer to Figure 7 , in this embodiment, the installation mechanism 6 uses a U-shaped gripper. Insert the base 71 of the limb rehabilitation assistive device 7 into the U-shaped gripper. The U-shaped gripper clamps and fixes the base 71 of the limb rehabilitation assistive device 7 under the action of the internal elastic member.

[0080] Of course, asFigure 8 As shown, the mounting mechanism 6 in this embodiment can also adopt Figure 8 the magnetic chuck shown, and fix the base 71 of the limb rehabilitation assistive device 7 by adsorbing with the magnetic chuck, so as to mount the limb rehabilitation assistive device 7 on the mounting mechanism 6.

[0081] Of course, the mounting mechanism 6 in this embodiment can also adopt a bolt mounting mechanism 6 similar to Figure 3 shown, or Figure 9 the rectangular tubular mounting frame shown, or other mechanisms such as a square box tray that are convenient for connecting and fixing with the base 71 of the limb rehabilitation assistive device 7.

[0082] The mounting plane of the mounting mechanism 6 is set horizontally, so as to keep the limb rehabilitation assistive device 7 in a horizontal state during the displacement process and use process, which is stable and safe.

[0083] It should be noted that the limb rehabilitation assistive device 7 described in this embodiment can be, for example, a limb rehabilitation assistive device 7 with joint angle training requirements such as a crank-slider type, a crank-rocker type, a swing guide rod type, and a crank-block type. Using the displacement device of this embodiment, by horizontally moving the limb rehabilitation assistive device 7, the basic angles required for joint training can be ensured to remain unchanged.

[0084] Embodiment Four

[0085] As Figure 9 shown, this embodiment introduces a fourth displacement device. The displacement device includes a base 1, a support frame 2, a displacement adjustment mechanism 3, a first connection mechanism 4, and a mounting mechanism 6. Compared with the displacement device in Embodiment One, the difference is that the displacement device in this embodiment does not have a second connection mechanism 5, the first connection mechanism 4 is directly fixedly connected to the mounting mechanism 6, and the shape of the mounting mechanism 6 is different, while other structures are basically the same, so they will not be described repeatedly.

[0086] As Figure 9 shown, in this embodiment, the mounting mechanism 6 adopts a rectangular tubular mounting frame, the axis of the rectangular tubular mounting frame is arranged along the horizontal direction, and the end of the first connection mechanism 4 that is not connected to the displacement adjustment mechanism 3 is fixedly connected to the top of the rectangular tubular mounting frame.

[0087] It should be noted that the limb rehabilitation assistive device 7 described in this embodiment can be, for example, a limb rehabilitation assistive device 7 with joint angle training requirements such as a crank-slider type, a crank-rocker type, a swing guide rod type, and a crank-block type. Among them, Figure 10 the connection schematic diagram between the upper limb training mechanism and the rectangular tubular mounting frame is shown, and the support component of the upper limb training mechanism is inserted and fixed in the rectangular tubular mounting frame; Figure 11The connection schematic diagram between the crank-rocker type lower limb training mechanism and the rectangular tubular mounting frame is shown, and the support component of the crank-rocker type lower limb training mechanism is inserted and fixed in the rectangular tubular mounting frame.

[0088] It can be understood that the mounting mechanism 6 in this embodiment can also be replaced by other mechanisms such as a bolt mounting mechanism 6, a magnetic chuck, a U-shaped gripper or a square box tray that are convenient for connecting and fixing with the base 71 of the limb rehabilitation assistive device 7.
