DETAILED DESCRIPTION

[0023] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0024] Figure 1 is a perspective view of a joint rehabilitation training device provided by an embodiment of the present application; Figure 2 is an exploded view of a joint rehabilitation training device provided by an embodiment of the present application.

[0025] As shown in Figure 1 and Figure 2 , the present application provides a joint rehabilitation training device, which comprises a driving motor 1, a connecting assembly 2 and a training assembly 3. The driving motor 1 transmits power to the training assembly 3 through the connecting assembly 2, thereby driving the part of a patient in need of training to do circumferential movement, which can promote the recovery of the affected part.

[0026] The connecting assembly 2 comprises a first connecting piece 21 and a second connecting piece 22, the first connecting piece 21 is detachably connected to the output end of the driving motor 1, the second connecting piece 22 is connected to the training assembly 3, the first connecting piece 21 and the second connecting piece 22 have mutual magnetic attraction force, so that the second connecting piece 22 can be mounted on the first connecting piece 21, and the driving motor 1 can transmit power to the second connecting piece 22 and the training assembly 3 through the first connecting piece 21. At the same time, through the magnetic attraction of the first connecting piece 21 and the second connecting piece 22 of the connecting assembly 2, the transmission efficiency is guaranteed, the training assembly 3 and the driving motor 1 are quickly disassembled and assembled, the replacement efficiency of the training assembly 3 mounted on the driving motor 1 is improved, and the applicability of the joint rehabilitation training equipment is improved.

[0027] The driving motor 1 can output torque to drive the training assembly 3 to move, and the driving motor 1 can be a permanent magnet synchronous motor. The training assembly 3 is used for covering or fixing the part of the patient that needs to be trained, and the specific shape can be adjusted according to the affected part of different patients. For example, when the affected part is the elbow, the training assembly 3 can be a cylindrical structure with a cavity inside, which is used to accommodate the elbow of the patient. After the patient places the elbow in the cavity, the driving motor 1 is started to drive the training assembly 3 to move, and the rehabilitation training of the elbow is completed. When the affected part is the ankle, the training assembly 3 can be a long strip structure, and the patient can fix the foot on the training assembly 3, and the driving motor 1 drives the training assembly 3 and the foot of the patient to move, and the rehabilitation training of the ankle is completed.

[0028] In addition, by setting the detachable connection of the first connecting piece 21 and the driving motor 1, and the detachable connection of the second connecting piece 22 and the training assembly 3, the first connecting piece 21 and the second connecting piece 22 can also be replaced at any time, thereby further improving the convenience of use.

[0029] Figure 3 is a structure diagram of the connecting assembly of the joint rehabilitation training equipment provided by the embodiment of the application; Figure 4 is a sectional view of the connecting assembly of the joint rehabilitation training equipment provided by the embodiment of the application.

[0030] As Figure 3 and Figure 4As shown, in one preferred embodiment, the first connecting piece 21 is provided with a protrusion 211, and the second connecting piece 22 is provided with a groove 221; or the first connecting piece 21 is provided with a groove 221, and the second connecting piece 22 is provided with a protrusion 211; the protrusion 211 is matched with the groove 221, and the protrusion 211 is clamped into the groove 221. By matching the protrusion 211 and the groove 221 between the first connecting piece 21 and the second connecting piece 22, the first connecting piece 21 and the second connecting piece 22 can be conveniently disassembled while having good connection strength.

[0031] Further, in Figure 3 As shown in the embodiment, the first connecting piece 21 is provided with a protrusion 211 extending in the radial direction, and the second connecting piece 22 is provided with a groove 221 matching the protrusion 211 extending in the radial direction. When the protrusion 211 is matched with the groove 221, the first connecting piece 21 and the second connecting piece 22 can stably transmit torque, thereby improving the training effect of the training assembly 3.

[0032] In one preferred embodiment, the protrusion 211 and the groove 221 can be respectively provided with a plurality of protrusions 211 and grooves 221 arranged in a straight line in correspondence, so as to further improve the connection strength of the first connecting piece 21 and the second connecting piece 22. Moreover, by matching the protrusion 211 and the groove 221, the first connecting piece 21 and the second connecting piece 22 have a larger contact area when matched with each other, so that the magnetic attraction matching of the first connecting piece 21 and the second connecting piece 22 is more firm, thereby improving the reliability and safety of the joint rehabilitation training device.

[0033] In addition, the protrusion 211 can be integrally formed with the first connecting piece 21 or the second connecting piece 22, and the groove 221 can be integrally formed with the second connecting piece 22 and the first connecting piece 21 in correspondence, so as to further improve the connection strength of the first connecting piece 21 and the second connecting piece 22 and improve the reliability of the joint rehabilitation training device.

[0034] As shown in the embodiment, Figure 3 and Figure 4 In one preferred embodiment, an inclined surface 4 can be provided on the protrusion 211, and an inclined matching surface can be provided on the groove 221 to abut and match the inclined surface 4. As shown in the embodiment, Figure 4 The inclined surface 4 and the inclined matching surface make the size of the protrusion 211 gradually decrease from the root to the end, and the size of the groove 221 gradually increase from the root to the end, so as to guide the matching of the protrusion 211 and the groove 221. After the protrusion 211 is placed in the groove 221, the protrusion 211 can be naturally embedded in the groove 221 under the guidance of the magnetic attraction and the inclined surface 4, thereby realizing the connection of the first connecting piece 21 and the second connecting piece 22.

[0035] Based on the setting mode of the inclined surface 4 and the inclined matching surface, the convex part 211 can form a trapezoidal body, and the shape of the groove 211 is matched with the shape of the trapezoidal body. When the convex part 211 is clamped into the groove 221, the inclined surface 4 on the convex part 211 abuts against the inclined matching surface on the groove 221, so that the first connecting piece 21 and the second connecting piece 22 can be more firmly attached. In addition, a high friction force can be formed between the inclined surface 4 and the inclined matching surface, so that the driving force generated by the driving motor 1 can be transmitted to the training assembly 3. The inclination angle of the inclined surface 4 is in the range of 11 degrees to 15 degrees (°), and exemplarily can be 11°, 12°, 13°, 14°, 15°, and preferably 13°.

[0036] As shown in Figure 4 In one preferred embodiment, a first magnetic attraction part 212 is formed on the first connecting piece 21, and a second magnetic attraction part 222 corresponding to the first magnetic attraction part 212 is formed on the second connecting piece 22, and the first magnetic attraction part 212 and the second magnetic attraction part 222 generate magnetic attraction force to attract each other. The first magnetic attraction part 212 and the second magnetic attraction part 222 can be respectively formed on the plane when the first connecting piece 21 and the second connecting piece 22 are in contact, so that the first magnetic part and the second magnetic part can be completely attached when they attract each other, effectively improving the connection firmness of the first connecting piece 21 and the second connecting piece 22.

[0037] The first magnetic attraction part 212 formed on the first connecting piece 21 and the second magnetic attraction part 222 formed on the second connecting piece 22 can ensure that the connecting assembly 2 has a simple connection structure, and also can realize quick and convenient disassembly of the driving motor 1 and the training assembly 3. In some embodiments, the number of the first magnetic attraction part 212 and the second magnetic part is multiple, and the multiple first magnetic attraction parts 212 and the multiple second magnetic parts correspond to each other respectively. The multiple first magnetic attraction parts 212 and the multiple second magnetic parts can be respectively and symmetrically arranged on the first connecting piece 21 and the second connecting piece 22, so that the first connecting piece 21 and the second connecting piece 22 can form uniform magnetic attraction force. In this way, the multiple first magnetic attraction parts 212 and the multiple second magnetic parts can generate stronger magnetic attraction force between the first connecting piece 21 and the second connecting piece 22, further improving the reliability and safety of the joint rehabilitation training equipment.

[0038] Alternatively, the first connecting piece 21 and / or the second connecting piece 22 can be made of a magnetic material as a whole, so that the first connecting piece 21 and the second connecting piece 22 can have good magnetic attraction and cooperation strength.

[0039] Figure 5 is a structural schematic view of the first limiting piece and the second limiting piece of the joint rehabilitation training equipment provided by the embodiment of the present application.

[0040] As Figure 5 shown, in one preferred embodiment, the first limiting piece 5 is connected with the driving motor 1, and the second limiting piece 6 is arranged on the side of the first connecting piece 21 close to the driving motor 1. When the training assembly 3 is subjected to resistance, specifically, when the affected part of the patient cannot smoothly follow the movement of the training assembly 3 to generate a reaction force on the training assembly 3, the rotational movement of the training assembly 3, the second connecting piece 22 and the first connecting piece 21 is blocked, and then the relative movement between the first connecting piece 21 and the output end of the driving motor 1 occurs, so that the first limiting piece 5 and the second limiting piece 6 abut each other, and then the driving motor 1 stops running.

[0041] Through the above arrangement, the driving motor 1 has an automatic emergency stop function in an emergency. When the patient has an accident during the training process, the affected part applies a force to the training assembly 3, and the direction of the force is opposite to that of the driving force of the driving motor 1. At this time, the first limiting piece 5 is displaced relative to the second limiting piece 6 to stop the driving motor 1. This greatly ensures the safety of the user and effectively improves the safety and reliability of the joint rehabilitation training equipment.

[0042] The first limiting piece 5 can be fixed on the side wall of the driving motor 1 facing the training assembly 3 by screwing or clamping. The second limiting piece 6 can also be fixed on the side wall of the first connecting piece 21 facing the driving motor 1 by screwing or clamping.

[0043] As Figure 5 shown, in one preferred embodiment, the first limiting piece 5 has a limiting groove 51 accommodating the second limiting piece 6, and the limiting groove 51 has a first position 511 and a second position 512 relative to the second limiting piece 6. When the training assembly 3 is subjected to resistance, the driving motor 1 drives the limiting groove 51 to move from the first position 511 to the second position 512 relative to the second limiting piece 6, and the limiting groove 51 abuts against the second limiting piece 6 at the second position 512.

[0044] The second limiting piece 6 can be displaced relative to the first limiting piece 5 along the limiting groove 51, and the edge of the limiting groove 51 is arc-shaped, which can play a guiding role to make the first limiting piece 5 and the second limiting piece 6 slide more smoothly when displaced. When the joint rehabilitation training equipment is in a normal use state, the first position 511 of the first limiting piece 5 abuts against the second limiting piece 6. When an emergency occurs, the first limiting piece 5 can be displaced in the opposite direction relative to the second limiting piece 6, and at this time, the second position 512 of the first limiting piece 5 abuts against the second limiting piece 6, and the driving motor 1 stops running.

[0045] Through the above setting, in the emergency state, the first limiting piece 5 can be displaced through the limiting groove 51 and the second limiting piece 6, so that the displacement between the first limiting piece 5 and the second limiting piece 6 is more smooth and reliable, effectively avoiding the disengagement during sliding, further improving the safety and reliability of the joint rehabilitation training equipment.

[0046] Figure 6 It is a structure diagram of the training assembly of the joint rehabilitation training equipment provided by the embodiment of the application.

[0047] As Figure 6 shown, in one of the preferred embodiments, the training assembly 3 comprises a fixing piece 31 and a supporting piece 32 slidingly arranged on the fixing piece 31, and the supporting piece 32 is connected with the second connecting piece 22 through the fixing piece 31. The fixing piece 31 is arranged on the side of the supporting piece 32 away from the part to be trained, and the supporting piece 32 is connected with the driving motor 1 through the fixing piece 31. The supporting piece 32 can be slidingly arranged on the fixing piece 31 to meet the difference in use requirements of different patients.

[0048] Among them, the supporting piece 32 can be provided with a long strip-shaped sliding groove 321, and the fixing frame can be provided with a sliding block 311 matched with the sliding groove 321. Through the relative displacement between the sliding groove 321 and the sliding block 311, the supporting piece 32 can make a linear motion relative to the fixing frame. Optionally, the shape of the sliding groove 321 on the supporting piece 32 can be curved or arc-shaped. In this way, the cooperation between the fixing frame and the supporting piece 32 can make the training assembly 3 meet different training requirements, thereby improving the universality of the joint rehabilitation training equipment.

[0049] As Figure 2 and Figure 6 shown, the training assembly 3 further comprises a fastener 33, and the affected part can be attached to the supporting piece 32 through the fastener 33. For example, the fastener 33 can be a bandage. Through the bandage, the affected part of the patient can be fixed on the supporting piece 32 by binding or clamping, which can improve the stability of the connection between the affected part and the supporting piece 32, avoid the affected part from being separated from the supporting piece 32 during use, and effectively ensure the training effect of the joint rehabilitation training equipment.

[0050] In addition, the training assembly 3 can be provided as two, and the two training assemblies 3 are arranged on opposite sides of the driving motor 1 and connected with the driving motor 1 through the connecting assembly 2. In this way, the training assemblies 3 arranged on opposite sides of the driving motor 1 can enable the user to perform bilateral or unilateral rehabilitation training according to the actual situation or use requirements, thereby meeting the different rehabilitation training requirements of the user and effectively improving the user's experience.

[0051] Finally, it should be noted that the above examples are merely used to illustrate the technical solutions of the present application but not to limit the present application. Although the present application is explained in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and all of these should be covered in the scope of the claims of the present application.
