Cooperating with the first elastic airbag 220 and the second elastic airbag 223, they can wrap the calf and thigh of the patient. Then, through the first hydraulic transmission component, the second hydraulic transmission component, and the third hydraulic transmission component, the joints, calves, and thighs are driven to move. Under the action of the energy storage conversion module, there are two modes;

[0049] Energy storage mode: When the first bone wall 222, the second bone arm 211, and the foot support component on the normal side are operating, that is, the first hydraulic transmission component, the second hydraulic transmission component, and the third hydraulic transmission component are driven to operate through the activities of the human body, completing the energy storage process of the energy storage conversion module;

The oil discharge port 1012 corresponds to and communicates with the first aperture 4121, and the oil inlet port 1022 corresponds to and communicates with the second aperture 4122.

[0056] Further, the valve core body 1018 includes a valve core body 1018.

Two connecting cross bars 1017 are connected to the front end of the valve core body 1018. The two connecting cross bars 1017 penetrate through the first chamber 1013 and are fixed with magnetic attraction pieces 1016, and an electromagnet 1015 is fixed on the outer wall of the first chamber 1013.

[0057] As Figure 9 、 10 As shown in FIGS. 11 and 12, the valve core body 1018 can slide back and forth in the second chamber 1019. The driving mode of the power: by controlling the attraction generated by the operation of the electromagnet 1015 and the magnetic attraction piece 1016, the valve core body 1018 is driven to slide to the right;

A plurality of first apertures 4121 are connected in parallel and converge with the second flow channel 4113. Since they are in a "凵"-shaped structure and extend to the second inlet 912 port, the liquid is pressed into the normal pressure chamber 911. Since the oil inlet 1022 corresponds to and is connected with the second aperture 4122 in one-to-one correspondence, they are used for liquid suction, that is, a plurality of first apertures 4121 are connected in parallel and converge in the first flow channel 4112. The first flow channel 4112 is in an "L"-shaped structure, and one end of the first flow channel 4112 is connected with the first inlet 814, and is used for sucking liquid from the pressurized chamber 811. In this process, the first hydraulic transmission assembly, the second hydraulic transmission assembly and the third hydraulic transmission assembly are driven to operate through the body on the normal side. Under the action of the valve body assembly, the oil in the normal pressure tank is continuously drawn into the pressurized tank. Under the structural action of the refueling tank, pressurization and energy storage are performed. Figure 9 shown.

[0061] Example 3

[0062] As another embodiment of the present invention, the pipeline switching assembly includes a main pipe rack 711, one end of which is connected to the interior of the normal pressure chamber 911, and the other end is extended with three groups of interfaces and respectively installed with switching valve bodies 712, each of which drives the switching valve body 712 to fork into two channel tubes 713, and the two channel tubes 713 are connected to the second chamber 1019 where the two adjacent valve bodies 1011 are located.

[0063] In this embodiment, based on the switching function of the valve body assembly in the foregoing embodiment and in combination with the setting of the pipeline switching assembly, specifically, when the driving electromagnet 1015 operates, under the magnetic attraction of the magnetic attraction piece 1016 and the electromagnet 1015, the valve core body 1018 is driven to move rightward. At this time, the second through groove 10182 communicates with the second through hole 1024, and the area corresponding to the first through hole 1021 is blocked at this time. The first through groove 10181, the second through groove 10182, the second through hole 1024, and the third through hole 1025 are communicated, indirectly connecting the channel pipe 713 with the corresponding third liquid guide pipe 314, fourth liquid guide pipe 315, sixth liquid guide pipe 515, fifth liquid guide pipe 514, second liquid guide pipe 121, and first liquid guide pipe 120, as Figure 9 , 10 and as shown in 11, when the switching valve body 712 at the corresponding position operates, the oil inside the atmospheric pressure chamber 911 can be connected to the channel pipe 713 at the corresponding position, and can act in the reverse direction on the corresponding third liquid guide pipe 314, fourth liquid guide pipe 315, sixth liquid guide pipe 515, fifth liquid guide pipe 514, second liquid guide pipe 121, and first liquid guide pipe 120, that is, the corresponding first hydraulic transmission assembly, second hydraulic transmission assembly, and third hydraulic transmission assembly operate. When the control is in one-to-one correspondence, the normal side of the body completes energy storage, supplies energy to the other side of the body, and through the movement of this normal body, then acts in the reverse direction on the body of the other patient and moves symmetrically with it, forming a walking gait to assist in driving the movement of this torso.

[0064] Embodiment 4

[0065] As other embodiments of the present invention, a balance flywheel 413 is further provided in the middle of the rear side of the frame body 412, which can be used to increase the stability of the device.

[0066] Under the action of this structure, the stability of the body is further strengthened. By setting the balance flywheel 413, according to the principle of conservation of angular momentum, after the balance flywheel 413 rotates at a high speed, an inertia makes it not undergo a large azimuth change in a short time, which is equivalent to a function of increasing stability, and when the patient walks, it helps prevent him from falling.
