Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "plurality" is two or more.

[0030] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0031] In addition, the technical features involved in different embodiments of the present utility model described above can be combined with each other as long as they do not conflict with each other.

[0032] The present utility model provides a device for stretching the calves of a cerebral palsy patient's legs as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , which is used to assist patients in lower limb rehabilitation training. When in use, the lower limb exercise device is used to assist the patient's lower limbs in lifting the feet and performing lower limb training actions such as stretching the muscles of the thighs and calves. Its main structure includes: a seat 1 and a lower limb training mechanism 2. The seat 1 at least includes a seat base 11. In addition, the seat 1 may further include structures such as armrests and a backrest. Further, the angle of the seat back is adjustable; the lower limb training mechanism 2 is connected to the seat base 11, and the lower limb training mechanism 2 includes at least one exoskeleton mechanical leg 21; the exoskeleton mechanical leg 21 includes a thigh support member 211, a calf support member 212, a foot support member 213, a first driving member 214, a second driving member 215, and a third driving member 216. The thigh support member 211, the calf support member 212, and the foot support member 213 are sequentially movably connected through a first movable shaft 217 and a second movable shaft 218. That is: the thigh support member 211 and the calf support member 212 are connected through the first movable shaft 217; the calf support member 212 and the foot support member 213 are connected through the second movable shaft 218. One end of the thigh support member 211 away from the calf support member 212 is connected to the seat base 11 through a third movable shaft 219. The first movable shaft 217 and the second movable shaft 218 extend in a first direction, and the third movable shaft 219 extends in a second direction; the directions of the first direction and the second direction are as shown in Figure 3 .

[0033] Among them, the first driving member 214 and the second driving member 215 are respectively used to adjust the angle between the calf support member 212 and the foot support member 213, and the angle between the thigh support member 211 and the calf support member 212. The third driving member 216 is used to drive the thigh support member 211 to rotate around the third movable shaft 219. In this way, it assists the patient in performing training operations such as moving the feet and stretching the calves. The first driving member 214, the second driving member 215, and the third driving member 216 can adopt a hydraulic or electric drive form. Specifically, it can be selected according to actual needs. Among them, the initial angle between the calf support member 212 and the foot support member 213 can be configured to be less than 180°, so as to help patients who cannot straighten their legs perform training more smoothly.

[0034] Further, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the lower limb training mechanism 2 includes two exoskeleton mechanical legs 21. In this embodiment, two exoskeleton mechanical legs 21 arranged in parallel are preferably used as the lower limb training mechanism 2. They are arranged in parallel on the seat base 11, and further, a cushion is arranged on the thigh support 211. When in use, the patient sits on the cushion, with both legs corresponding to the two exoskeleton mechanical legs 21, and the calf and the sole of the foot are fixed on the calf support 212 and the sole support 213 respectively.

[0035] Further, such as Figure 2 As shown, the two exoskeleton mechanical legs 21 are respectively movably connected to the seat base 11 through two third movable shafts 219, and the ends of the two thigh support members 211 away from the calf support member 212 are respectively provided with gear plates 2111, and the axis of the gear plates 2111 is provided with a connecting hole 2112, and the third movable shaft 219 is penetrated in the connecting hole 2112, so that the thigh support member 211 is movably connected to the seat base 11;

[0036] The axis of the gear plate 2111 coincides with the axis of the third movable shaft 219 , and the gear plates 2111 on the two thigh supports 211 mesh with each other, so that the two exoskeleton mechanical legs 21 form a structure that can be synchronously expanded or retracted.

[0037] It should be noted that, in this embodiment, the gear plates 2111 on the two thigh supports 211 mesh with each other, so as long as one of them rotates, the other gear plate 2111 will be driven to rotate, and then the two exoskeleton mechanical legs 21 will open and close at the same time, so that the two can achieve a linkage effect. And the opening and closing degrees of the two exoskeleton mechanical legs 21 can always remain consistent.

[0038] Further, such as Figure 3 and Figure 4 As shown, a slide rail 2131 is provided on the foot support 213 , and the slide rail 2131 extends along the length direction of the foot support 213 . A slider 2132 is slidably connected to the slide rail 2131 , and a foot support plate 2133 is provided on the end of the slider 2132 away from the slide rail 2131 .

[0039] In this embodiment, a slide rail 2131 is provided on the sole support member 213, and the slide rail 2131 extends along the length direction of the sole support member 213. A slider 2132 is slidably connected to the slide rail 2131. Furthermore, a limiting portion is provided on the slider 2132, so that it can only slide on the slide rail 2131 and will not separate from the slide rail 2131. A sole support plate 2133 is provided on one end of the slider 2132 away from the slide rail 2131, and the sole support plate 2133 is used to support and fix the sole of the patient's foot.

[0040] It should be noted that since the axis of rotation of the sole support member 213 is not the same as the axis of the patient's ankle movement, when the sole support member 213 moves, the patient's sole and calf will be pulled, and in severe cases, it will cause harm to the patient's ankle. In this embodiment, the slide rail 2131 and the slider 2132 between the sole support plate 2133 and the sole support member 213 form a buffer structure. When the sole support member 213 moves, a displacement will occur between the sole support plate 2133 and the sole support member 213, so that the patient's sole can stretch flexibly.

[0041] Furthermore, as Figure 3 and Figure 4 shown, an elastic member 2134 is provided on the sole support member 213. The two ends of the elastic member 2134 are respectively connected to the sole support member 213 and the slider 2132. The slider 2132 stays in the middle of the slide rail 2131 through the elastic member 2134.

[0042] In this embodiment, the angle between the patient's sole and calf is close to ninety degrees under normal conditions. The angle between the sole support plate 2133 and the calf support member 212 is also close to ninety degrees in the unactivated state. When training the patient's sole and calf, it is necessary to repeatedly change the angle between the two to be greater than ninety degrees and less than ninety degrees, that is, to move the patient's sole.

[0043] Therefore, when the device is not in use, the elastic member 2134 acting to keep the slider 2132 in the middle position of the slide rail 2131 can buffer the ineffective stress on the patient's sole in two directions.

[0044] Furthermore, as Figure 3 and Figure 4 shown, a first telescopic member 2121 and a second telescopic member 2113 are respectively provided on the calf support member 212 and the thigh support member 211; the extending direction of the first telescopic member 2121 is the same as the extending direction of the calf support member 212; the extending direction of the second telescopic member 2113 is the same as the extending direction of the thigh support member 211;

[0045] The first telescopic member 2121 and the second telescopic member 2113 are respectively used to adjust the lengths of the calf support member 212 and the thigh support member 211.

[0046] In this embodiment, the functions of the first telescopic member 2121 and the second telescopic member 2113 are similar to those described in the previous embodiment. The first telescopic member 2121 and the second telescopic member 2113 can also play a buffering role. Since the axis when the calf support member 212 moves is not the same as the axis when the patient's knee moves, when the calf support member 212 moves, the patient's calf and thigh will be pulled, and in severe cases, it will cause harm to the patient's knee. Therefore, the first telescopic member 2121 and the second telescopic member 2113 can effectively release the ineffective stress on the patient's calf and thigh.

[0047] It can be understood that the specific functions of the first telescopic member 2121 and the second telescopic member 2113 in this embodiment can be obtained by those skilled in the art according to the prior art, and the structures and working principles of the first telescopic member 2121 and the second telescopic member 2113 will not be elaborated here.

[0048] Furthermore, as Figure 3 and Figure 4 shown, the calf support member 212 and the thigh support member 211 can respectively adjust their lengths by adjusting the first telescopic member 2121 and the second telescopic member 2113, so that the device can be used to match patients of different heights.

[0049] Furthermore, a first soft pad 2122 and a second soft pad 311 are respectively provided on the calf support member 212 and the thigh support member 211. It can be understood that the first soft pad 2122 and the second soft pad 311 are respectively used to support the patient's calf and thigh to improve the comfort of the patient during training.

[0050] Furthermore, a first fixing member 2135, a second fixing member 2123 and a third fixing member 310 are respectively provided on the foot sole support plate 2133, the calf support member 212 and the thigh support member 211. The first fixing member 2135, the second fixing member 2123 and the third fixing member 310 are respectively used to fix the patient's foot sole, calf and thigh to prevent the patient's lower limbs from loosening from the training device.

[0051] Furthermore, the first fixing member 2135, the second fixing member 2123 and the third fixing member 310 are configured as a strap structure.

[0052] It can be understood that the strap structure is simple in structure and can adjust its length as needed to ensure that the patient's leg and the device maintain a proper position.

[0053] Furthermore, a fourth driving member 312 is also provided between the thigh support member 211 and the third driving member 216. The fourth driving member 312 is used to drive the thigh support member 211 to rotate around the third direction as the axis, where the indication of the third direction is as Figure 3As shown in the figure. It should be noted that the fourth driving member 312 can further assist the patient in leg movement training, specifically helping the patient correct internal rotation of the thigh.

[0054] In summary, the present application provides a device for stretching the calves of cerebral palsy patients. In the solution of the present application, the first driving member 214, the second driving member 215, and the third driving member 216 respectively drive the foot sole support member 213, the calf support member 212, and the thigh support member 211, so as to perform training actions such as lifting the patient's foot and stretching the thigh and calf muscles. Moreover, there is a buffer distance between the foot sole support plate 2133 and the foot sole support member 213, so that the stress of the foot sole movement is released during the process of stretching the calf, avoiding injury to the foot sole.

[0055] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
