[0002] To fully address the challenges of an aging population, labor shortages, and rising costs, research and development of intelligent robots for the elderly is underway. Lower limb rehabilitation training robots, as an effective means of enhancing the motor function of disabled or semi-disabled elderly individuals, not only help delay functional decline and improve their quality of life, but also enhance their ability to live independently.

[0003] A lower-limb exoskeleton is essentially a wearable robot designed to expand the mobility of the human lower limbs and reduce the physical exertion of weight-bearing and walking. Among the components of a lower-limb exoskeleton, the foot structure is the most complex in terms of movement and force distribution. Therefore, research on lower-limb exoskeletons generally begins with studying the foot's gait.

[0004] In this regard, hydraulic power-assisted shoes, as a part of the lower limb exoskeleton robot, are of great significance to the research of the lower limb exoskeleton robot. For example, a Chinese patent (application publication number CN115229766A) discloses a hydraulic power-assisted shoe for an exoskeleton robot. Its structure explores and improves the operational flexibility and wearing comfort of the hydraulic power-assisted shoe for the lower limb exoskeleton robot. Some hydraulic power-assisted shoes on the market explore aspects such as the shock absorption and breathability of the soles. In short, the structure of existing hydraulic power-assisted shoes is generally relatively simple, and cannot achieve a good power-assisted effect, and thus cannot achieve the purpose of saving effort.

[0062] The thrust ring 801 is sleeved between the front cylinder tube 401 and the rear cylinder tube 402 in the cylinder part 4 and can rotate relative to the cylinder shell and move back and forth with the cylinder shell.

[0063] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use. Example 6

[0064] See also Figure 1-8 The oil cylinder part 4 includes an oil cylinder front tube 401, an oil cylinder rear tube 402, a guide rod 403, a fixing block 404, a piston 405, a pipe joint 406 and a nut 407;

[0065] One end of the piston 405 is fastened to the hole of the fixed block 404 by a nut 407, and the fixed block 404 is welded to the base plate 2; two pipe joints 406 are provided, which are fixedly mounted on the fixed block 404 and are respectively connected to the high-pressure and low-pressure oil holes inside the piston 405; the front tube 401 of the cylinder and the rear tube 402 of the cylinder are respectively inserted into the piston 405 and fixed with threads to form a cylinder shell, and the cylinder shell moves back and forth and rotates relative to the piston 405, and the front tube 401 of the cylinder and the piston 405 are sealed with a sealing ring; the guide rod 403 is fixedly mounted on the side wall of one end of the rear tube 402 of the cylinder, and one end of it is inserted into the circular frame plate 103 below the control pedal 101. The guide rod 403 controls the rotation of the cylinder shell as the control pedal 101 moves up and down.

[0066] Furthermore, in this embodiment, a first circulation groove 408 and a second circulation groove 412 are provided at one end of the piston 405, and a piston low-pressure groove 409 and a piston high-pressure groove 410 are also provided at the other end. A communication groove 411 corresponding to the positions of the piston low-pressure groove 409 and the piston high-pressure groove 410 is provided on the cylinder front tube 401; through the setting of the above-mentioned grooves, different circulation circuits of high-pressure oil can be formed, and at the same time, the piston low-pressure groove 409 or the piston high-pressure groove 410 and the communication groove 411 can be connected or closed to each other in conjunction with the rotation of the cylinder shell, thereby realizing the telescopic movement of the cylinder shell.

[0067] Specifically, when using Figure 7-8 As shown, when the oil cylinder housing moves toward the fixed block 404, the communication groove 411 on the oil cylinder rear tube 402 is connected with the piston low-pressure groove 409 and the second flow groove 412 on the piston 405;

[0068] At this point, the high-pressure oil in the system enters the oil chamber A9 through the high-pressure end pipe joint 406 and the first flow groove 408 opened inside the piston 405. As a result, the high-pressure oil squeezes the annular walls on both sides of the oil chamber 1. Since the left annular wall belongs to the fixed side wall of the piston 405, the high-pressure oil can only squeeze the annular wall of the cylinder front tube 401, pushing the cylinder to the right.

[0069] When the cylinder moves rightward, the oil in the oil chamber C11 is squeezed into the oil chamber B10 through the piston low-pressure groove 409 and the communication groove 411, and then returns to the interior of the piston 405 through the second flow groove 412, and then returns to the pipe joint 406 at the low-pressure end, and then returns to the oil tank connected to the pipe joint 406;

[0070] That is, the cylinder housing will continue to move to the right until the left side of the cylinder housing hits the right side of the piston and the volume of the oil chamber C11 becomes 0. At this time, the guide rod 403 is in its original position.

[0071] When the control rod 403 is rotated by pressure, the cylinder housing rotates along with it because it is fixedly connected to the control rod 403. As a result of the rotation of the cylinder housing, the communication groove 411 on the cylinder rear tube 402 rotates and connects to the piston high-pressure groove 410, and the piston low-pressure groove 409 is closed.

[0072] At this time, the system's high-pressure oil not only enters oil chamber A9, but also enters oil chamber C11. Due to the volume of the piston in oil chamber A9, the force-bearing area of ​​oil chamber A9 is smaller than the force-bearing area of ​​oil chamber C11. The rightward thrust of the high-pressure oil in oil chamber A9 on the cylinder is smaller than the leftward thrust of the high-pressure oil in oil chamber C11 on the cylinder. Therefore, the cylinder moves to the right, and the high-pressure oil enters oil chamber C11, while the high-pressure oil in oil chamber 1 is squeezed out. Since the volume of oil chamber B10 remains unchanged, no oil enters or exits oil chamber B10.

[0073] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use.

[0074] The working principle and specific use process of the hydraulic power-assisted shoes:

[0075] The hydraulic power shoe is initially in a horizontal state and in a balanced position. When the forefoot of a person steps on the control pedal 101, the guide rod 403 is inserted into the circular frame 103 below the control pedal 101, and the guide rod 403 moves downward along with the control pedal 101.

[0076] The downward movement of the guide rod 403 will drive the cylinder housing of the cylinder part 4 to rotate. At this time, the cylinder begins to move to the left. The thrust ring 801 is installed between the front cylinder tube 401 and the rear cylinder tube 402. It can rotate relative to the cylinder housing, that is, it remains stationary. Therefore, the thrust ring 801 will move to the left with the cylinder housing but will not rotate with it.

[0077] Therefore, when the control pedal 101 is under force, the thrust ring 801 moves to the left driven by the cylinder housing, and the bearing 803 on the fixed shaft 802 of the thrust ring 801 pushes the bent hinge 6 as the thrust ring 801 moves to the left. The rotational movement of the bent hinge 6 is converted into the rotational movement of the rotating plate 301 and the side plate 302 through cooperation with the short hinge 5. As the cylinder housing moves to the extreme left, the rotating plate 301 rotates to the highest point.

[0078] When a person's heel steps on the rotating plate 301, the control pedal 101 is no longer subjected to downward force and moves upward under the action of the four return springs 102, driving the guide rod 403 to move upward, causing the cylinder housing to rotate in the opposite direction and start moving back until it returns to its original position. The rotating plate 301 then rotates in the opposite direction and returns to its original horizontal position.

[0079] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present utility model. Therefore, based on the innovative concept of the present utility model, changes and modifications to the embodiments described herein, or equivalent structures, equivalent processes, or equivalent functional transformations made using the contents of the present utility model specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields, are all included in the scope of protection of the present utility model patent.
