DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] Please refer to the attached Figure 1-4 The utility model provides an upper limb exercise device for stroke patients, comprising two support frames 1 and a seat 2, wherein the seat 2 is located between the two support frames 1, and the two support frames 1 are connected to support plates 3 through a lifting and adjusting component, and top plates 4 are horizontally fixed to the tops of the two support plates 3, and a first exercise component for assisting the stroke patient's upper limb extension and swinging is arranged on the top plate 4, and a second exercise component for weight-bearing exercise of the stroke patient's upper limb is also arranged on the top plate 4;

[0026] The first exercise component includes two reducers 5. It should be noted that the reducer is a transmission device for low speed and high torque. The power of the high-speed motor is decelerated by meshing the gear with a small number of teeth on the input shaft of the reducer with the large gear on the output shaft. The bottom of the two reducers 5 is symmetrically fixed at the two ends of the top of the top plate 4. A servo motor 6 is fixed on the top of the reducer 5. The output shaft of the servo motor 6 is fixedly connected to the input shaft of the reducer 5. The output shaft of the reducer 5 vertically penetrates the top plate 4, and a connecting rod 7 is fixed to the bottom end of the output shaft of the reducer 5. A swing plate 8 is fixed to the bottom end of the connecting rod 7. A first pull ring 9 is fixed to the bottom of the front end of the swing plate 8. Specifically, under the deceleration action of the reducer 5, when the two servo motors 6 run in reverse, the two swing plates 8 can be driven to move toward or in reverse through the connecting rod 7 (such as Figure 5 and Figure 6As shown in the figure), the two first pull rings 9 are driven to move toward or in the opposite direction. The stroke patient can hold the two first pull rings 9 with both hands, so that the patient's upper limbs move toward or in the opposite direction synchronously with the two first pull rings 9. That is, the exercise device can well assist the stroke patient in performing upper limb extension exercise. When the two servo motors 6 run in the same direction, the two swing plates 8 can be driven to reciprocate in the same direction through the connecting rod 7 (as shown in the figure). Figure 7 and Figure 8 As shown), the two first pull rings 9 are driven to reciprocate in the same direction. At this time, when the stroke patient holds the two first pull rings 9 with both hands, the upper limbs of the stroke patient can reciprocate in the same direction synchronously with the two first pull rings 9, that is, the exercise device can well assist the stroke patient in performing swinging exercise on the upper limbs;

[0027] The second exercise component includes two limiting holes 10, and the two limiting holes 10 are symmetrically opened at both ends of the top plate 4. A lifting rod 11 is vertically penetrated in each limiting hole 10, and the hole wall of the limiting hole 10 is in contact with the surface of the lifting rod 11, that is, under the limiting action of the limiting hole 10, the lifting rod 11 can be stably lifted and lowered, and a top limiting plate 12 is fixed to the top of the lifting rod 11. A reset spring 13 is sleeved on the surface of the lifting rod 11, and the top end of the reset spring 13 is fixedly connected to the bottom of the top limiting plate 12, and the bottom end of the reset spring 13 is fixedly connected to the top of the top plate 4. A bottom limit plate 14 is fixed, and a second pull ring 15 is fixed at the bottom end of the bottom limit plate 14. Therefore, under the joint limiting action of the top limit plate 12 and the bottom limit plate 14, the lifting rod 11 can be effectively prevented from falling off. Specifically, the stroke patient can hold the second pull ring 15 with both hands and then pull it downward. When the second pull ring 15 is pulled downward with both hands, the lifting rod 11 can be driven to move downward, so that the reset spring 13 undergoes elastic deformation to generate a reaction force, and the effect of weight-bearing exercise can be achieved. Therefore, the exercise device can well assist the stroke patient in performing weight-bearing exercise on the upper limbs.

[0028] The lifting and adjusting assembly includes a plurality of first threaded holes 16, and the plurality of first threaded holes 16 are symmetrically opened at both side ends of the support frame 1 from top to bottom. The bottom end of the support plate 3 is inserted into the support frame 1, and a plurality of second threaded holes 17 are opened at the bottom end of the support plate 3 from top to bottom. A fixing bolt 18 is threadedly connected between the second threaded hole 17 and the first threaded hole 16. Specifically, under the action of the fixing bolt 18, the support plate 3 can be fixedly connected to the support frame 1, and the caregiver only needs to disassemble and assemble the fixing bolt 18 and adjust the connection between the fixing bolt 18 and the first threaded holes 16 at different heights to control the lifting and lowering of the support plate 3, thereby controlling the lifting and lowering of the top plate 4, thereby controlling the height adjustment of the two first pull rings 9 and the two second pull rings 15, so that it can be well suitable for stroke patients with different upper limb lengths to use for exercise;

[0029] A first shell 19 is fixed on the top of the top plate 4, and the reducer 5, servo motor 6, top limit plate 12 and reset spring 13 are all located in the first shell 19. A heat dissipation hole 20 is opened at the side end of the first shell 19, which can be used for heat dissipation when the servo motor 6 is running. Second shells 21 are symmetrically fixed at both ends of the bottom of the top plate 4, and the bottom end of the output shaft of the servo motor 6 and the top end of the connecting rod 7 are both located in the second shell 21. A through hole 22 is opened at the bottom of the second shell 21, and the bottom end of the connecting rod 7 vertically passes through the through hole 22. Specifically, under the action of the first shell 19 and the second shell 21, not only can its internal structure be protected from dust and other protection operations, but also the overall aesthetics of the exercise device can be effectively improved.

[0030] It should be noted that the device is electrically connected to an external main controller and 220V mains electricity, and the main controller can be a computer or other prior art equipment for control.

[0031] The use process of the utility model is as follows: first, the caregiver can adjust the height of the two first pull rings 9 and the two second pull rings 15 to a suitable height according to the height of the stroke patient by disassembling and assembling the fixing bolts 18 and adjusting the connection between the fixing bolts 18 and the first threaded holes 16 of different heights, and then let the stroke patient sit on the seat 2. When weight-bearing exercise is needed, the stroke patient holds the second pull ring 15 with both hands and then pulls it downward. When the second pull ring 15 is pulled downward with both hands, the lifting rod 11 can be driven to move downward, so that the reset spring 13 undergoes elastic deformation to generate a reaction force, and the effect of weight-bearing exercise can be achieved. Therefore, the exercise device can well assist the stroke patient in weight-bearing exercise of the upper limbs. When extended exercise is needed, the user controls the two servo motors 6 to run in reverse. When the two servo motors 6 run in reverse, the two swing plates 8 can be driven to move toward or in the opposite direction (such as Figure 5 and Figure 6 As shown in the figure), the two first pull rings 9 are driven to move toward or in the opposite direction, so that the upper limbs of the patient move toward or in the opposite direction synchronously with the two first pull rings 9, that is, the exercise device can well assist the stroke patient to perform upper limb extension exercise. When swing exercise is required, the user controls the two servo motors 6 to run in the same direction. When the two servo motors 6 run in the same direction, the two swing plates 8 can be driven to reciprocate in the same direction through the connecting rod 7 (as shown in the figure). Figure 7 and Figure 8 As shown), the two first pull rings 9 are driven to reciprocate in the same direction, so that the upper limbs of the stroke patient can reciprocate in the same direction synchronously with the two first pull rings 9, that is, the exercise device can well assist the stroke patient in performing swinging exercise on the upper limbs;

[0032] In summary, the exercise device not only has the function of weight-bearing exercise for the upper limbs of stroke patients, but can also well assist stroke patients in extension and swinging exercises of the upper limbs, and also has a height adjustment function, so that it can be suitable for stroke patients with different upper limb lengths to use for exercise, greatly improving its practicality and being suitable for promotion.

[0033] The above is only a preferred embodiment of the utility model. Any person skilled in the art can modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
