[0043] like Figures 1 to 12As shown, an embodiment of the present invention provides a lower limb rehabilitation training brace with a fixing function, including a first support frame 1 and a second support frame 2, the first support frame 1 and the second support frame 2 are movably connected through an adjustable joint mechanism 3, the adjustable joint mechanism 3 has a locking function, the adjustable joint mechanism 3 is located at the connecting portion of the first support frame 1 and the second support frame 2, and a locking head is arranged on the adjustable joint mechanism 3, which can lock or unlock the adjustable joint mechanism 3 by sliding, and can also limit the movable range of the first support frame 1 and the second support frame 2, limit the training movements of the patient, and avoid secondary injuries during rehabilitation training. The principle and use process of the adjustable joint mechanism 3 are the same as those in the prior art, and will not be described in detail here. A fixing seat 16 and a charging seat 4 are fixedly installed on the first support frame 1 and the second support frame 2, and a plastic sheet 5, a gasket 6 and a sliding seat 8 are sleeved on the outside of the first support frame 1 and the second support frame 2, and the gasket 6 is fixedly connected and surrounds the plastic sheet 5, the slide seat 8 is fixedly connected to the outside of the gasket 6, the first support frame 1 and the second support frame 2 are both two groups, and two gaskets 6 and slide seats 8 are arranged on a first support frame 1 and a second support frame 2, and the gaskets 6 on adjacent first support frames 1 and adjacent second support frames 2 are connected and fixed by connecting belts 7. The lower limb rehabilitation training brace corresponding to one leg of the patient is composed of two groups of first support frames 1 and second support frames 2. The setting of the gasket 6 and the connecting belt 7 can associate the two groups of first support frames 1 and second support frames 2 to form a whole. At the same time, the existence of the connecting belt 7 can also adjust the distance between the adjacent first support frames 1 and the adjacent second support frames 2, so as to adapt to the thickness of the lower limbs of patients with different body shapes, thereby further improving the adaptation range of the entire brace, the gasket 6 is arc-shaped, adapted to the external shape of the patient's lower limbs, and is a plastic structure with good deformation ability. After wearing, it can better surround the outside of the patient's lower limbs, and the comfort after wearing is higher;

[0044] The adjusting component is used to fix the relative position between the gasket 6 and the sliding seat 8 and the first supporting frame 1 and the second supporting frame 2. The adjusting component is connected to the fixing seat 16. The setting of the adjusting component improves the adjusting structure of the traditional brace, further expands the adjustable range, and the operation during the adjustment process is simple and convenient. It also has a preliminary fixing effect. Even after being worn on the outside of the lower limb, it can still be adjusted as long as it is not locked, avoiding repeated wearing, disassembly and adjustment operations; the locking component is used to lock the position of the gasket 6 and the sliding seat 8 after the position is adjusted. The locking components are respectively connected between the first supporting frame 1 and the second supporting frame 2. The locking component can lock the structure of the adjusting component after the adjusting component determines that the adjustment is completed, thereby This prevents the structure of the adjustment component from loosening due to accidental touching during the patient's subsequent rehabilitation training or getting out of bed, thereby ensuring the stability of the entire brace during use after wearing it; the fixing component is used to fix the relative position between the first support frame 1 and the second support frame 2, and is connected to the charging base 4. The setting of the fixing component can, on the one hand, lock the position of the first support frame 1 and the second support frame 2 during the patient's getting out of bed, so as to reduce the burden of fixing the adjustable joint mechanism 3, and at the same time, it can also synchronously limit the structure in the locking component, thereby further strengthening the locking effect of the locking component, allowing the structures of the entire brace to cooperate with each other and echo each other in effect, thereby improving the technical solution of the entire brace.

[0045] In this embodiment, if Figure 4 and Figure 7 as well as Figures 9 to 12As shown, the adjustment assembly includes a locking plate 9 sleeved in the fixed seat 16, and a uniformly distributed spring 30 is fixedly connected between the fixed seat 16 and the locking plate 9. The slide seat 8 surrounds the outer side of the fixed seat 16, and the inner side wall of the slide seat 8 is provided with uniformly distributed teeth. The outer side of the locking plate 9 is provided with teeth that match the shape of the slide seat 8. The locking plate 9 can move in the fixed seat 16. The locking plate 9 will compress the spring 30 in the process of moving away from the direction of the slide seat 8, so that the spring 30 accumulates elastic potential energy, but at the same time, the teeth on the locking plate 9 will also The teeth on the slide 8 split from each other, thereby releasing the locking state of the slide 8, and then the slide 8 can drive the gasket 6 to move and adjust on the outside of the fixed seat 16, changing the external position of the plastic sheet 5, the gasket 6 and the slide 8 on the first support frame 1 and the second support frame 2. Compared with the adjustment and fixing method of the latch fixing hole adopted in the transmission adjustment structure, the adjustment range is larger, and when the position of the locking plate 9 is not locked, even if the first support frame 1, the second support frame 2 and the gasket 6 have been worn, they can still be adjusted in the wearing state, and pulling the gasket 6 can drive the slide 8 The teeth on the locking plate 9 are displaced and squeezed to make the locking plate 9 move in the fixing seat 16, so as to adapt to the adjustment operation of the sliding seat 8 and the gasket 6, making the operation of the entire adjustment bracket more convenient and applicable to a wider range of scenarios. A pressing piece 19 is symmetrically installed in the middle of the locking plate 9, and the pressing piece 19 is provided with evenly distributed friction lines 20. A first movable groove 28 adapted to the shape of the pressing piece 19 is provided in the middle of the fixing seat 16, and a second movable groove 31 adapted to the shape of the pressing piece 19 is provided in the middle of the first support frame 1 and the second support frame 2. The setting of the pressing plate 19 makes the middle structure of the locking plate 9 be located on the outside of the fixing seat 16. The patient or relevant medical staff can drive the relative movement between the locking plate 9 and the fixing seat 16 by pressing the pressing plate 19. The setting of the first movable groove 28 and the second movable groove 31 ensures the movement range of the locking plate 9 and the pressing plate 19, avoiding obstruction to the movement process of the locking plate 9 and the pressing plate 19. The setting of the friction pattern 20 makes the contact area between the pressing plate 19 and the hand larger and the friction force greater during the process of pressing the pressing plate 19, thereby playing an anti-slip role.

[0046] In this embodiment, if Figures 4 to 10As shown, the locking assembly includes a connecting piece 21 fixedly connected to the outside of the first support frame 1 and the second support frame 2, the position of the connecting piece 21 corresponds to the position of the second movable groove 31, and the end of the connecting piece 21 is fixedly connected to the support block 22, and the outside of the support block 22 is fixedly connected to the paddle 17, the paddle 17 is Z-shaped, the connecting piece 21 is C-shaped, and a second weakened groove 27 is provided on the connecting piece 21. The setting of the connecting piece 21 forms a connection relationship between the support block 22 and the first support frame 1 and the second support frame 2. The setting of the second weakened groove 27 makes the thickness of the connecting piece 21 at the second weakened groove 27 thinner and weaker, and it is more likely to deform after being subjected to external force. The C-shaped structure of the connecting piece 21 enables the paddle 17 to drive the support block 22 to move, and causes the connecting piece 21 to deform to adapt to the displacement of the support block 22, thereby enabling the support block 22 to change its position between the pressing piece 19 and the second movable groove 31, so as to lock the pressing piece 19. and unlocking, the thickness value of the support block 22 is the same as the distance value between the pressing sheet 19 and the second movable groove 31, and the support block 22 extends into the first movable groove 28. When the support block 22 is completely inserted between the pressing sheet 19 and the second movable groove 31, the existence of the support block 22 fills the space between the pressing sheet 19 and the second movable groove 31, so that the pressing sheet 19 can no longer move between the second movable groove 31 and the first movable groove 28. A deformation groove 23 is provided on the support block 22 and a deformation plate 24 is formed by separating the deformation groove 23. A first weakening groove 26 is provided on the deformation plate 24, and a positioning strip 25 is provided on the outside of the deformation plate 24. The first weakening groove 26 forms a thinning at the connection between the deformation plate 24 and the support block 22, thereby making the strength of the deformation plate 24 at the first weakening groove 26 weaker. After being squeezed by external force, it is more likely to undergo adaptive deformation. A positioning groove 29 adapted to the shape of the positioning strip 25 is provided on the second movable groove 31.

[0047] When performing the locking operation on the pressing piece 19, first insert the end of the supporting block 22 and the deformable plate 24 into the gap between the pressing piece 19 and the second movable groove 31, then push the paddle 17 in the direction away from the second movable groove 31, drive the connecting piece 21 to deform at the second weakened groove 27, and make the supporting block 22 inserted toward the space between the pressing piece 19 and the second movable groove 31, then push the paddle 17 in the direction of the fixing seat 16, drive the supporting block 22 to insert between the pressing piece 19 and the second movable groove 31, during the process, the positioning strip 25 on the deformable plate 24 contacts the upper surface of the second movable groove 31 and is squeezed by the second movable groove 31, thereby making the deformable plate 24 bend and deform at the first weakened groove 26 and accumulate elastic potential energy, the deformation groove 23 is closed, the deformable plate 24 approaches the supporting block 22, and the area at the end of the supporting block 22 and the deformable plate 24 is smaller, until the supporting block 22 is completely inserted into the pressing piece When the pressing plate 19 is in the locked position, the support block 22 is locked to the position of the pressing piece 19. On the contrary, if the user wants to release the locked state, the paddle 17 is directly pulled in the direction away from the first electric excitation rod 10, so that the support block 22 withdraws from between the pressing piece 19 and the second movable groove 31, and the deformable plate 24 is bent and deformed at the first weakened groove 26 again, so that the positioning strip 25 withdraws from the positioning groove 29 until the support block 22 completely leaves the space between the pressing piece 19 and the second movable groove 31, so that the pressing piece 19 and the locking plate 9 can be moved, and then the plastic sheet 5, the gasket 6 and the slide seat 8 can be adjusted in position outside the first support frame 1 and the second support frame 2.

[0048] In this embodiment, if Figures 1 to 6As shown, the fixing assembly includes a second electric excitation rod 12 fixedly connected to the charging base 4 and symmetrically installed. A retractable second telescopic rod 13 is arranged in the second electric excitation rod 12. A limiting opening 18 adapted to the external shape of the paddle 17 is provided at the end of the second telescopic rod 13. When the patient wearing the brace needs to get out of bed, in order to ensure the fixation and protection effect of the brace on the patient's lower limbs, it is usually necessary to adjust the brace to a first state. In the first state, the first support frame 1 and the second support frame 2 are parallel and collinear to each other. In this state, the adjustable joint mechanism 3 is also in a locked state, maintaining the relative position between the first support frame 1 and the second support frame 2, so that the patient can get out of bed. After that, the joints of the lower limbs cannot move and bend, avoiding secondary injuries during the activity. The fixing components in this state work synchronously to reinforce the fixed state of the first support frame 1 and the second support frame 2. At the same time, the second electric excitation rod 12 on the charging base 4 also pushes the second telescopic rod 13 to extend, so that the end of the second telescopic rod 13 moves and is sleeved on the outside of the paddle 17, so that the paddle 17 cannot be displaced, and the paddle 17 in the locked state is further reinforced to avoid the locking effect of the locking component being affected by accidental touch during the patient's getting out of bed and moving. The spacing adjusts the working stability of the component, making the working environment of the locking component more stable.

[0049] A first electric excitation rod 10 is symmetrically installed in the charging seat 4 on the first support frame 1, and a third electric excitation rod 14 is symmetrically installed in the charging seat 4 on the second support frame 2. The positions of the first electric excitation rod 10 and the third electric excitation rod 14 correspond to each other, and the first electric excitation rod 10 and the third electric excitation rod 14 are respectively provided with a retractable first telescopic rod 11 and a third telescopic rod 15. The end of the first telescopic rod 11 is provided with a plug interface that is compatible with the shape of the end of the third telescopic rod 15. The first electric excitation rod 10, the first telescopic rod 11, the third electric excitation rod 14 and the third telescopic rod 15 are all in the adjustable joint mechanism 3. On the outside, the positions of the first electric excitation rod 10, the first telescopic rod 11, the third electric excitation rod 14 and the third telescopic rod 15 can avoid the existence of the adjustable joint mechanism 3 hindering the operation of the first electric excitation rod 10, the first telescopic rod 11, the third electric excitation rod 14 and the third telescopic rod 15. A sensor is provided on the charging seat 4. When the fixing component is working, the first support frame 1 and the second support frame 2 are in the first state to fix and protect the patient's lower limbs. The adjustable joint mechanism 3 is also in a locked state. The first telescopic rod 11 in the first electric excitation rod 10 and the first telescopic rod 11 in the third electric excitation rod 14 The three telescopic rods 15 are all in an extended state, and the end of the first telescopic rod 11 is fixedly connected to the end of the third telescopic rod 15, further strengthening the stability of the first support frame 1 and the second support frame 2 after the relative position is fixed, reducing the workload of the adjustable joint mechanism 3, and the exterior of the first telescopic rod 11 and the third telescopic rod 15 are made of hard plastic. After being connected, they have high strength, which can assist the brace in fixing the patient's lower limbs, and have a certain deformation ability, which can produce a certain deformation after wearing to match the first support frame 1 and the second support frame 2 with the shape of the patient's lower limbs. When the patient moves his lower limbs on the bed for rehabilitation training, the fixing component does not work and the adjustable joint mechanism 3 is also in an unlocked state. The relative position of the first support frame 1 and the second support frame 2 can be rotated and adjusted with the adjustable joint mechanism 3 as the axis, so that the patient can perform rehabilitation training. A sensor is also provided on the charging base 4, which can record the number of activities when the first support frame 1 and the second support frame 2 produce displacement activities, and enter the data into the smart device for monitoring, so as to monitor and determine the patient's rehabilitation training intensity. The principle and use process of this sensor are the same as those of the prior art and will not be elaborated here.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
