[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-3 The utility model provides an embodiment: a multi-posture lower limb rehabilitation training device, including a base plate 1, a motor 2 is installed on the base plate 1, the output end of the motor 2 is fixedly connected to a bevel gear 3, the bevel gear 3 is meshed with a bevel gear 4, the bevel gear 4 is fixedly connected to a screw rod 5, the bevel gear 3 connected to the output end of the motor 2 is meshed with the bevel gear 4, when the motor 2 is started, the bevel gear 3 and the bevel gear 4 are driven to rotate, thereby transmitting the rotational motion of the motor 2 to the screw rod 5, the screw rod 5 is rotationally connected to the base plate 1, the screw rod 5 is threadedly connected to a threaded sleeve 6, the screw rod 5 is connected to the threaded sleeve 6 through a thread, and the screw rod 5 is connected to the threaded sleeve 6 through a thread. The rotational motion is converted into the linear movement of the threaded sleeve 6. A support frame 7 is fixedly installed at the bottom of the base plate 1. The threaded sleeve 6 is slidably connected to the support frame 7. When the threaded sleeve 6 moves linearly, the support frame 7 limits the linear motion of the threaded sleeve 6. The threaded sleeve 6 is hinged with a slider 8. A support column 9 is fixedly connected to the base plate 1. A seat 10 is fixedly connected to the upper part of the support column 9. The seat 10 is hinged with a backrest 11. A slide groove 12 is provided on the backrest 11. The slider 8 slides in the slide groove 12 on the backrest 11, thereby driving the backrest 11 to achieve angle adjustment, thereby changing the inclination of the seat 10 to adapt to different postures of the user such as lying, semi-lying, sitting, etc.

[0027] A motor 2 13 is fixedly connected to the bottom of the base plate 1, and a turntable 14 is fixedly connected to the output end of the motor 2 13, which is responsible for the power of the lower limb rehabilitation training part. After starting, the turntable 14 is driven to rotate. A connecting shaft 15 is fixedly connected to the turntable 14, and the connecting shaft 15 is rotatably connected to a connecting rod 16, and the connecting rod 1 16 is hinged to a connecting rod 2 17, and the connecting rod 2 17 is hinged to a connecting rod 3 18, and the connecting rod 3 18 is hinged to a leg brace 20. A rotating shaft 19 is fixedly connected to the base plate 1, and the leg brace 20 is rotatably connected to the rotating shaft 19 to transmit the swing of the connecting shaft 15. The connecting rods 1 16, 17, and 18 are hinged to transmit the motion to the leg brace 20, and the leg brace 20 is used for the user to place the legs.

[0028] An ankle brace 21 is installed above the leg brace 20. The ankle brace 21 is used for the user to place the ankle and provide fixation and support for the ankle.

[0029] A roller 22 is installed at the bottom of the leg brace 20. When the leg brace 20 rotates around the rotating shaft 19, the roller 22 rotates on the ground accordingly, thereby reducing friction during movement and improving the smoothness of movement.

[0030] An armrest 23 is mounted on the seat 10 to provide additional comfort and support for the user.

[0031] The connecting shaft 15 is arranged at a non-center position of the rotating disk 14. Due to the eccentric connection between the connecting shaft 15 and the rotating disk 14, the connecting shaft 15 and the connected connecting rod 16 swing back and forth.

[0032] The support columns 9 are arranged at the four corners of the bottom of the seat 10 . There are four support columns 9 . The support columns 9 provide support for the seat 10 and maintain the stability of the seat 10 .

[0033] Working principle: The user starts the motor, and through the start of motor 12, the bevel gear 13 is driven to rotate, and then meshes with bevel gear 24, so that the screw 5 fixedly connected to bevel gear 24 rotates. The thread on the screw 5 is connected to the threaded sleeve 6, and the rotational movement of the screw 5 is converted into the linear movement of the threaded sleeve 6. The support frame 7 on the base plate 1 limits the linear movement of the threaded sleeve 6 to ensure that the threaded sleeve 6 moves safely along the screw 5. The threaded sleeve 6 is hinged with a slider 8, and the slider 8 slides in the slide groove 12 on the backrest 11, driving the backrest 11 to adjust the angle, thereby changing the inclination of the seat 10 to adapt to the user's different postures such as lying, semi-lying, sitting, etc. The user adjusts the inclination of the seat 10 by controlling the start and stop of motor 12 according to his own rehabilitation stage and comfort requirements. The operation of motor 12 allows the backrest 11 to be adjusted within a preset angle range;

[0034] The user sits on the seat 10, places the legs on the leg brace 20, and places the ankles on the ankle brace 21. The armrests 23 on the seat 10 provide additional comfort and support for the user. Then the motor 2 13 is started. The motor 2 13 starts and drives the turntable 14 to rotate. Due to the eccentric connection between the connecting shaft 15 and the turntable 14, the connecting shaft 15 and the connected connecting rod 1 16 swing back and forth. The swing of the connecting rod 16 is transmitted through the connecting rod 2 17 and the connecting rod 3 18, and finally drives the leg brace 20 to rotate around the rotating shaft 19. The rotation of the leg brace 20 drives the user's legs to expand and close together, simulating the natural swing of the legs, which helps to restore the function of the lower limbs. The rollers 22 installed at the bottom of the leg brace 20 rotate on the ground.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
