Description

Technical Field

[0001] This invention relates to the field of sports rehabilitation training robot technology, specifically to a lower limb supine rehabilitation brace for sports rehabilitation training. Background Technology

[0002] With the rapid development of the manufacturing industry, robotic arms are increasingly being used in manufacturing, medical and other fields. To achieve sports rehabilitation training based on robotic arms, the end of the robotic arm needs to be connected to the limbs of the person being rehabilitated through a set of suitable support devices (here called rehabilitation braces) to achieve organic connection and fixation between the human and the machine, so as to traction and drag the limbs to complete rehabilitation movements.

[0003] Most existing rehabilitation braces are fixed in design, used for immobilization and protection after injury, but they have poor adaptability and are not suitable for sports rehabilitation training. Braces for sports rehabilitation training robots, especially for lower limb joint rehabilitation, are very rare, and generally fall into two categories: one primarily fixes the leg, targeting knee and hip joint rehabilitation exercises, but offering little protection for ankle joint movements; the other considers joints such as the knee, hip, and ankle simultaneously, implemented through linkages, guide rails, and other mechanisms, but these are complex to design, costly to manufacture, and heavy.

[0004] For the first type of rehabilitation brace, if the patient needs to fix the ankle, it cannot meet the user's needs for sports rehabilitation training because there are no fixation parts. For the second type of rehabilitation brace, due to the large number of movable parts and high precision requirements, the processing difficulty and production cost are high, the weight is heavy, and the requirements for collaborative robotic arms are high. Therefore, we propose a lower limb supine rehabilitation brace for sports rehabilitation training. Summary of the Invention

[0005] The purpose of this invention is to provide a lower limb supine rehabilitation brace for sports rehabilitation training, so as to solve the problems to be solved in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lower limb supine rehabilitation brace for sports rehabilitation training, comprising a leg fixation plate and a foot fixation plate. A slide rail is fixedly mounted on the surface of the leg fixation plate, and a sliding member is slidably connected to the surface of the slide rail. Semi-circular first connecting members are hinged to both sides of the foot fixation plate via first pins. A first pull rod is fixedly connected to the top of the first connecting member. One end of the first pull rod is hinged to one side of the sliding member via a second pin. A U-shaped connecting pull rod is hinged to the surface of the foot fixation plate, located on one side of the first pin, via a third pin. One side of the connecting pull rod is fixedly mounted on the surface of the leg fixation plate. Multiple sets of indexing pin locking holes are formed through the surface of the leg fixation plate. Indexing pins are provided on the surface of the sliding member, and these indexing pins are inserted into the locking holes. Buffer blocks are fixedly mounted on both sides of the leg fixation plate, corresponding to the positions of the sliding members, to block the sliding members.

[0007] Preferably, the leg fixing plate includes a first mounting plate and a second mounting plate. The second mounting plate is fixedly connected to both sides of the first mounting plate at an angle. A U-shaped connecting rod is fixedly connected to one side of the top of the first mounting plate by three sets of fixing screws.

[0008] Preferably, the sliding component includes a slider, a mounting base, a tongue, an indexing pin support, and a support frame. The slider is slidably connected to the outer surface of the slide rail, and the mounting base is fixedly connected to the outer surface of the slider. An indexing pin support is fixedly installed on one side of the bottom of the mounting base by a fixing threaded pin. An indexing pin is fixedly installed inside the indexing pin support, and the bottom of the indexing pin is inserted into the inside of the indexing pin locking hole. A tongue is fixedly connected to the top of the mounting base, and a support frame is fixedly connected to one side of the mounting base.

[0009] Preferably, the tongue is fixedly connected to an external robotic arm.

[0010] Preferably, the buffer blocks are provided in three sets. Two sets of buffer blocks are fixedly connected to one side of the top of the indexing pin locking hole and the position corresponding to the mounting base, and one set of buffer blocks is provided on the other side of the top of the indexing pin locking hole and the position corresponding to the mounting base.

[0011] Preferably, the first pull rod includes a connecting rod and a sleeve. The connecting rod is configured as an "L" shape. One end of the connecting rod is fixedly connected to the first connecting member, and the other end of the connecting rod is fixedly connected to the sleeve. The sleeve overlaps the inside of the support frame. One end of the support frame is provided with a second pin. One end of the second pin passes through the inside of the sleeve and extends to the other end of the support frame.

[0012] Preferably, the foot fixing plate includes a third mounting plate and a mounting bracket. Mounting brackets are fixedly installed on both sides of the top of the third mounting plate. The mounting brackets are triangular in shape. A first mounting hole is opened through the top of the triangular mounting bracket. A connecting rod is hinged inside the first mounting hole through a third pin. A second mounting hole is opened through the surface of the triangular mounting bracket. A first connecting member is hinged inside the second mounting hole through a first pin.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention uses a type of indexing pin to lock the foot fixation plate and the leg fixation plate at different positions of the indexing pin locking holes on the surface of the leg fixation plate, so that the foot fixation plate and the leg fixation plate can be fixed at different angles. This design can meet the needs of patients undergoing rehabilitation for different angles due to their lower limb conditions, etc. In addition, the operation is simple and convenient, and unlocking and locking can be achieved quickly, by using an indexing pin to lock the foot fixation plate with an indexing pin locking hole.

[0018] 2. The relative rotation of the foot fixing plate and the leg fixing plate is achieved by linear motion of a single slide rail, which is easy to install. The single slide rail is easy to install and has low requirements for processing precision. This structure is simple, reliable and has low manufacturing cost.

[0019] 3. The joint position connecting the foot fixation plate and the first connector is designed according to ergonomics.

The shape of the leg fixation plate and foot fixation plate, as well as the position and size of the straps and pad mounting holes, are designed according to the size of the human foot and calf. The design adopts the ergonomic design method and is used with pads and straps for easy wearing. It can better fit the skin and provide more comfortable and reliable coverage. This design is lightweight and can achieve a greater net weight load output, thereby expanding the range of applicable people. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1This invention provides a technical solution: a supine lower limb rehabilitation brace for sports rehabilitation training, comprising a leg fixation plate 1 and a foot fixation plate 2. A slide rail 3 is fixedly mounted on the surface of the leg fixation plate 1, and a sliding member 4 is slidably connected to the surface of the slide rail 3. Semi-circular first connecting members 6 are hinged to both sides of the foot fixation plate 2 via first pins 5. A first pull rod 7 is fixedly connected to the top of the first connecting member 6, and one end of the first pull rod 7 is hinged to one side of the sliding member 4 via a second pin 8. A U-shaped... The connecting rod 10 is fixedly installed on one side of the leg fixing plate 1. The surface of the leg fixing plate 1 has multiple sets of indexing pin locking holes 11. The surface of the slide 4 is provided with indexing pins 12. The indexing pins 12 are inserted into the interior of the indexing pin locking holes 11. The indexing pins 12 are spring-loaded pins. Pulling up and rotating the top of the indexing pins 12 can lock them in place, so that the root of the indexing pins 12 can be disengaged from the interior of the indexing pin locking holes 11. Both sides of the surface of the leg fixing plate 1 are fixedly installed with buffer blocks 20 to block the slide 4.

[0029] The foot fixation plate 2 and the leg fixation plate 1 are locked together at different positions by the indexing pin 12 and the indexing pin locking hole 11 on the surface of the leg fixation plate 1, so that the foot fixation plate 2 and the leg fixation plate 1 can be fixed at different angles. This setting can meet the needs of patients undergoing rehabilitation for different angles due to their lower limb conditions. The operation is simple and convenient, and the locking and unlocking can be achieved quickly by the indexing pin 12 and the indexing pin locking hole 11. The foot fixation plate 2 and the leg fixation plate 1 are fixed to rotate relative to each other by the linear movement of the single slide rail 3 and the slide 4. The installation is convenient, and the single slide rail 3 is easy to install and has low processing precision requirements. This structure is simple and reliable and has low manufacturing cost.

[0030] Please see Figure 2 and Figure 3 The leg fixing plate 1 includes a first mounting plate 13 and a second mounting plate 14. The second mounting plate 14 is fixedly connected to both sides of the first mounting plate 13 at an angle. The top side of the first mounting plate 13 is fixedly connected to a "U"-shaped connecting rod 10 by three sets of fixing screws.

[0031] The second mounting plate 14 is installed at an angle on both sides of the first mounting plate 13. This arrangement can wrap the leg during the process of fixing the leg fixation plate 1 to the patient's leg, thereby preventing the leg fixation plate 1 from shifting from the patient's leg.

[0032] Please see Figure 1 , Figure 2 and Figure 4The sliding component 4 includes a slider 15, a mounting base 16, a tongue 17, an indexing pin support 18, and a support frame 19. The slider 15 is slidably connected to the outer surface of the slide rail 3. The mounting base 16 is fixedly connected to the outer surface of the slider 15. The indexing pin support 18 is fixedly installed on one side of the bottom of the mounting base 16 by a fixing threaded nail. An indexing pin 12 is fixedly installed inside the indexing pin support 18. The bottom of the indexing pin 12 is inserted into the inside of the indexing pin locking hole 11. The tongue 17 is fixedly connected to the top of the mounting base 16. The support frame 19 is fixedly connected to one side of the mounting base 16.

[0033] When the indexing pin 12 is pulled upward to the top and rotated at a certain angle, the indexing pin 12 can be locked in the upper position. At this time, the root of the indexing pin 12 can disengage from the indexing pin locking hole 11. The slider 15 allows the entire device to move along the outer surface of the slide rail 3. The first pull rod 7 and the first connecting piece 6, which are hinged by the second pin 8 on one side of the mounting base 16, can make the leg fixing plate 1 and the foot fixing plate 2 present corresponding angles when the entire slide 4 moves along the slide rail 3.

[0034] Please see Figure 1 and Figure 4 The tongue 17 is fixedly connected to the external robotic arm. When the robotic arm moves, if the indexing pin 12 is locked, the human leg will move with the robotic arm. When the indexing pin 12 is locked in different indexing pin locking holes 11, the foot fixing plate 2 and the leg fixing plate 1 are at different angles. This setting can meet the needs of patients undergoing rehabilitation for different angles due to their lower limb condition. When the robotic arm moves, if the indexing pin is in the highest locked position, the human lower leg basically remains still. The robotic arm drives the tongue 17 and the slider 4 to make linear movements on the slide rail 3. Correspondingly, this setting can make the slider 4 drive the foot fixing plate 2, the first connecting piece 6 and the first pull rod 7 to make linkage movements.

[0035] Please see Figure 1 The buffer block 20 is provided in three sets. Two sets of buffer blocks 20 are fixedly connected to one side of the top of the indexing pin locking hole 11 and the position corresponding to the mounting base 16. One set of buffer blocks 20 is provided on the other side of the top of the indexing pin locking hole 11 and the position corresponding to the mounting base 16.

[0036] When the robotic arm drives the slide 4 to move along the slide rail 3, one side of the movement boundary is when the slide 4 is in contact with the uppermost buffer block 20. At this time, the angle between the plane of the foot fixation plate 2 and the vertical plane is 55°. The other side of the movement boundary is when the slide 4 is in contact with the lowermost single buffer block 20. At this time, the angle between the plane of the foot fixation plate 2 and the vertical plane is 35°. This setting allows the robotic arm to drive the foot fixation plate 2 to perform reciprocating rehabilitation training. The buffer blocks 20 on one side are set as a group to avoid the slide 4 blocking the buffer blocks 20 and affecting the normal movement of the indexing pin support 18.

[0037] Please see Figure 1 and Figure 5 The first pull rod 7 includes a connecting rod 21 and a sleeve 22. The connecting rod 21 is L-shaped. One end of the connecting rod 21 is fixedly connected to the first connecting member 6, and the other end of the connecting rod 21 is fixedly connected to the sleeve 22. The sleeve 22 overlaps the inside of the support frame 19. One end of the support frame 19 is provided with a second pin 8. One end of the second pin 8 passes through the inside of the sleeve 22 and extends to the other end of the support frame 19.

[0038] The sleeve 22, which is hinged to the support frame 19 by the second pin 8, can drive the foot fixing plate 2, the first connecting piece 6 and the first pull rod 7 to perform linkage movement during the movement of the entire sliding piece 4.

[0039] Please see Figure 1 and Figure 6 The foot fixing plate 2 includes a third mounting plate 23 and a mounting bracket 24. The mounting bracket 24 is fixedly installed on both sides of the top of the third mounting plate 23. The mounting bracket 24 is triangular. A first mounting hole 25 is opened through the top of the triangular mounting bracket 24. A connecting rod 10 is hinged inside the first mounting hole 25 through a third pin 9. A second mounting hole 26 is opened through the surface of the triangular mounting bracket 24. A first connecting piece 6 is hinged inside the second mounting hole 26 through a first pin 5.

[0040] The mounting bracket 24 is triangular and is installed at the middle of both sides of the top of the third mounting plate 23. The first mounting hole 25 and the second mounting hole 26 can be used to hinge the connecting rod 10 and the first connector 6.

[0041] The surface of the mounting bracket 24 is provided with two sets of first strap grooves 27 for installing foot straps. One end of each of the two mounting brackets 24 is provided with two sets of third strap grooves 31 for installing heel straps. The two sets of first strap grooves 27 can be used to bind the straps, thus binding the patient's foot. The two sets of third strap grooves 31 can be used to bind the patient's heel. In this way, the two sets of straps can fix the entire patient's foot inside the foot fixation plate 2.

[0042] The top of the third mounting plate 23 has a first pad mounting hole 28 and a second pad mounting hole 29 on both sides. The first pad mounting hole 28 and the second pad mounting hole 29 can place the external pad on the top of the third mounting plate 23. This arrangement can ensure that the patient has sufficient comfort when using the device.

[0043] Please see Figure 1 and Figure 2 Both sets of the second mounting plates 14 have a second strap groove 30 through which the lower leg strap is installed. The second strap groove 30 can fix the patient's lower leg inside the first mounting plate 13 and the second mounting plate 14. This setting can prevent the patient's lower leg from coming off the surface of the leg fixation plate 1 during rehabilitation exercises.

[0044] In use, firstly, the indexing pin 12 engages with different positions of the indexing pin locking holes 11 on the surface of the leg fixation plate 1, allowing the foot fixation plate 2 and the leg fixation plate 1 to be fixed at different angles. This design can meet the needs of patients undergoing rehabilitation for different angles due to their lower limb conditions. Furthermore, the fixing via the indexing pin 12 and the indexing pin locking holes 11 is simple and convenient to operate, allowing for quick unlocking and locking. The relative rotation of the foot fixation plate 2 and the leg fixation plate 1 is achieved through the linear motion of a single slide rail 3 and a sliding component 4, and installation is convenient. The single slide rail 3 is easy to install and requires low machining precision. This design is structurally simple. The design is reliable and has low manufacturing cost. The second mounting plate 14 is installed at an angle on both sides of the first mounting plate 13. This arrangement allows the leg to be wrapped during the fixation of the leg fixation plate 1 and the patient's leg. The second strap groove 30 allows the patient's lower leg to be fixed inside the first mounting plate 13 and the second mounting plate 14. This design prevents the patient's lower leg from detaching from the surface of the leg fixation plate 1 during rehabilitation exercises, thus preventing displacement between the leg fixation plate 1 and the patient's leg. When the indexing pin 12 is pulled upward to the top and rotated at a certain angle, the indexing pin 12 can be locked in the upper position.At this point, the root of the indexing pin 12 can disengage from the indexing pin locking hole 11. The slider 15 allows the entire device to move along the outer surface of the slide rail 3. The first pull rod 7 and the first connecting piece 6, hinged on one side of the mounting base 16 by the second pin 8, allow the leg fixing plate 1 and the foot fixing plate 2 to present corresponding angles when the entire slide 4 moves along the slide rail 3. The tongue 17 is fixedly connected to the external robotic arm. When the robotic arm moves, if the indexing pin 12 is locked, the human leg will move with the robotic arm. When the indexing pin 12 is locked in different positions, the foot fixing plate 2 and the leg fixing plate 1 are at different angles relative to each other. This setup can meet the different angle needs of patients undergoing rehabilitation due to their lower limb conditions. When the robotic arm moves, if the indexing pin 12 is in the highest locked position, the lower leg remains basically still. The robotic arm drives the tongue 17 and the slider 4 to move linearly on the slide rail 3. Correspondingly, this setup allows the slider 4 to drive the foot fixing plate 2, the first connecting piece 6, and the first pull rod 7 to perform linkage motion. Furthermore, when the external robotic arm drives the slider 4 to move along the slide rail 3, one side of the movement boundary is when the slider 4 is in contact with the uppermost buffer stop 20. At this time, the angle between the plane of the foot fixing plate 2 and the vertical plane is 55°, while the other side moves... When the boundary is such that the slide 4 is in contact with the single buffer block 20 at the bottom, the angle between the plane of the foot fixing plate 2 and the vertical plane is 35°. This setting allows the robotic arm to drive the foot fixing plate 2 to perform reciprocating rehabilitation training. The buffer blocks 20 on one side are set as a group to prevent the buffer blocks 20 from affecting the normal movement of the indexing pin support 18 when the slide 4 is moving. The sleeve 22 inside the support frame 19 is hinged to the second pin 8, which can drive the foot fixing plate 2, the first connecting piece 6 and the first pull rod 7 to perform linkage movement during the entire movement of the slide 4. The mounting frame 24 is set as a triangle and is installed on the middle of both sides of the top of the third mounting plate 23. The mounting bracket 24 is positioned such that the first mounting hole 25 and the second mounting hole 26 allow for hinged connection between the connecting rod 10 and the first connecting piece 6. Two sets of first strap grooves 27 for installing foot straps are provided through the surface of the mounting bracket 24. Two sets of third strap grooves 31 for installing heel straps are provided through one end of each set of mounting brackets 24. The two sets of first strap grooves 27 allow for binding of the straps, thus securing the patient's foot. The two sets of third strap grooves 31 secure the patient's heel. This arrangement of straps secures the entire patient's foot within the foot fixation plate 2.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
