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.

[0075] Example 1

[0076] A type of orthopedic leg rehabilitation exercise bed, such as Figures 1-7As shown, the device includes support legs 1, bed frame 2, servo motor 3, drive assembly 4, movable assembly 5, mounting assembly 6, placement block 7, connecting strap 8, and buckle 9. Support legs 1 are provided on both the left and right sides of the bottom of bed frame 2. Servo motor 3 is provided in the middle of the bottom of bed frame 2. Drive assembly 4 is provided on the right side of the bottom of bed frame 2. Movable assembly 5 is provided on the right side of the bottom of bed frame 2. Movable assembly 5 is located to the right of drive assembly 4. Mounting assembly 6 is provided on the right side of the top of bed frame 2. Two placement blocks 7 are rotatably provided on mounting assembly 6. Two connecting straps 8 are provided on the upper left side of the inner side of placement block 7. Buckles 9 are provided on the other end of connecting straps 8. Buckles 9 cooperate with placement blocks 7. The drive assembly 4 includes a drive rod 401, a first rotating rod 402, a first connecting rod 403, a second connecting rod 404, and a movable block 405. The drive rod 401 is mounted on the output shaft of the servo motor 3. The first rotating rod 402 is rotatably mounted on the middle right side of the bottom of the bed 2. The first connecting rod 403 is rotatably mounted between the middle of the first rotating rod 402 and the right side of the drive rod 401. The movable block 405 is slidably mounted on the middle right side of the bottom of the bed 2. The movable block 405 is located to the right of the first rotating rod 402. The second connecting rod 404 is rotatably mounted between the middle of the bottom of the movable block 405 and the right side of the first rotating rod 402. The movable block 405 has symmetrical locking holes 406 on its right side.

[0077] The movable component 5 includes a slider 501, a first spring 502, a connecting rod 503, a locking rod 504, and a second spring 505. The slider 501 is symmetrically slidably mounted on the top right side of the bed body 2. The first spring 502 is mounted between the lower part of the slider 501 and the bottom right side of the bed body 2. The connecting rod 503 is mounted on the lower left side of the slider 501. The connecting rod 503 is slidably engaged with the locking hole 406. The locking rod 504 is symmetrically slidably mounted on the inner side of the movable block 405. The second spring 505 is mounted between the locking rod 504 and the movable block 405. The connecting rod 503 has a locking groove 506 on its inner side. The locking rod 504 engages with the locking groove 506.

[0078] The mounting assembly 6 includes a shaped clamping block 601, a third spring 602, and a push rod 603. The upper inner side of the slider 501 is symmetrically equipped with shaped clamping blocks 601. The placement block 7 is rotatably installed between the shaped clamping blocks 601 on the same side. The middle outer side of the shaped clamping block 601 is equipped with a third spring 602 between it and the slider 501. The lower inner side of the slider 501 is equipped with a push rod 603, which cooperates with the shaped clamping block 601.

[0079] When a patient needs to perform leg rehabilitation exercises, first, have the patient lie on top of the bed 2, then place both feet on the placement block 7, and then pull the buckle 9 outward to lock the placement block 7, so that the connecting strap 8 fixes the patient's feet. Then, start the servo motor 3. The output shaft of the servo motor 3 drives the drive rod 401 to rotate. The drive rod 401 drives the first rotating rod 402 to swing back and forth left and right through the first connecting rod 403. The first rotating rod 402 drives the movable block 405 to move back and forth left and right through the second connecting rod 404. The movable block 405 drives all its components to move back and forth left and right. Because the locking rod 504 locks the feet, the patient's feet are secured. The slot 506 drives the connecting rod 503 and the slider 501 to reciprocate left and right. The first spring 502 deforms adaptively and acts as a buffer. The slider 501 drives all its components to reciprocate left and right, causing the placement block 7 to move the patient's feet back and forth, so that the patient's legs can perform reciprocating flexion and extension movements to achieve the purpose of rehabilitation exercises. When the patient no longer needs to perform leg rehabilitation exercises, the servo motor 3 is turned off, the buckle 9 is opened, and then the buckle 9 is rotated inward, so that the connecting belt 8 releases the patient's feet, allowing the patient to remove their feet from the placement block 7 and finally leave the bed 2.

[0080] Example 2

[0081] Based on Example 1, such as Figures 8-12 As shown, it also includes an adjustment assembly 10, which includes a guide rail 1001, a movable frame 1002, a rotating block 1003, a second rotating rod 1004, a fourth spring 1005, a contact block 1006, and a fifth spring 1007. The bottom right side of the bed body 2 is symmetrically provided with guide rails 1001, and the number of guide rails 1001 is 4. The movable frame 1002 is slidably provided between the two guide rails 1001 on the same side in the transverse direction. The rotating block 1003 is symmetrically provided in the bottom right side of the bed body 2 in the transverse direction. The second rotating rod 1004 is slidably and rotatably provided on the outer side of the movable frame 1002. The fourth spring 1005 is provided between the bottom middle of the second rotating rod 1004 and the rotating block 1003 on the same side. The contact block 1006 is slidably provided on the inner side of the movable frame 1002. The contact block 1006 cooperates with the locking rod 504. The fifth spring 1007 is provided between the outer side of the contact block 1006 and the movable frame 1002 on the same side.

[0082] It also includes a pulling assembly 11, which includes a guide rod 1101, a pull rope 1102, a support frame 1103, a first guide wheel 1104, a mounting block 1105, a sixth spring 1106, a second guide wheel 1107, a limit rod 1108, a seventh spring 1109, and a shaped block 1110. The guide rod 1101 is symmetrically arranged front and back on the bottom right side of the bed body 2. The guide rod 1101 is located to the right of the guide rail 1001 on the right side. The support frame 1103 is provided on the top right side of the bed body 2. The first guide wheel 1104 is symmetrically rotatably arranged on the lower right side of the support frame 1103. The mounting block 1105 is symmetrically slidably arranged on the upper left side of the support frame 1103. The top of the mounting block 1105 is connected to the support frame 1104. A sixth spring 1106 is provided between 03. A second guide wheel 1107 is rotatably provided on the inner side of the mounting block 1105. A pull rope 1102 is provided between the right side of the contact block 1006 and the placement block 7 on the same side. The pull rope 1102 passes through the guide rod 1101 on the same side. The pull rope 1102 passes around the first guide wheel 1104 and the second guide wheel 1107 on the same side. A limit rod 1108 is symmetrically slidably provided on the bottom right side of the movable block 405. The limit rod 1108 cooperates with the contact block 1006. A seventh spring 1109 is provided between the lower part of the limit rod 1108 and the bottom of the movable block 405. A shaped block 1110 is provided on the inner right side of the movable frame 1002. The shaped block 1110 cooperates with the push rod 603.

[0083] When the patient does not wish to perform leg flexion and extension exercises, the movable frame 1002 can be pushed inward. The movable frame 1002 causes all its components to move inward, thereby rotating the second rotating rod 1004. The fourth spring 1005 adapts and deforms, fixing the position of the movable frame 1002, which in turn causes the rotating block 1003 to rotate. Then, the movable frame 1002 is released. When the movable block 405 reciprocates left and right, it causes all its components to reciprocate left and right. When the limiting rod 1108 contacts the contact block 1006, it is pressed down, causing the seventh spring 1109 to stretch. When the limiting rod 1108 passes the contact block 1006, the seventh spring 1109 returns to its original state, causing the limiting rod 1108 to move upward and reset, locking the connection. Contact block 1006 allows movable block 405 to drive contact block 1006 to reciprocate left and right. Simultaneously, contact block 1006 presses against latch 504, causing it to move inward. Second spring 505 compresses, causing latch 504 to release from latch 506. At this point, movable block 405 separates from connecting rod 503, and movable block 405 no longer drives slider 501 to reciprocate left and right. Slider 501 and all its components stop moving, thus preventing the patient's leg from reciprocating flexion and extension. Simultaneously, shaped block 1110 contacts push rod 603, causing push rod 603 to move upward. Push rod 603 presses against shaped clamp 601, causing it to move outward and open. Third spring 602 compresses, causing shaped clamp 601 to release placement block 7. When movable block 405 drives contact block 1... When the device moves to the left, the fifth spring 1007 stretches. Guided by the guide rod 1101, the first guide wheel 1104, and the second guide wheel 1107, the movable block 405 drives the placement block 7 upward via the pull rope 1102. The mounting block 1105 will adaptively move downward according to the weight of the patient's leg. The sixth spring 1106 stretches. When the movable block 405 drives the contact block 1006 to move to the right, the fifth spring 1007 returns to its original state, thereby relaxing the pull rope 1102. Under the action of gravity, the placement block 7 moves downward to reset, and the sixth spring 1106 returns to its original state, driving the mounting block 1105 upward to reset. This reciprocating motion allows the placement block 7 to move the patient's leg up and down repeatedly, achieving the desired exercise effect. The purpose is to allow the movable frame 1002 to be pulled outwards and reset when the patient does not wish to perform leg-raising movements. This repositions all components on the frame outwards, causing the second rotating rod 1004 and the rotating block 1003 to rotate and reset. At this point, the contact block 1006 separates from the locking rod 504 and the movable block 405. The movable block 405 will not cause the contact block 1006 to reciprocate left and right, thus stopping the contact block 1006 from moving and preventing the patient's leg from reciprocating up and down. Simultaneously, the second spring 505 returns to its original state, causing the locking rod 504 to move outwards and reset, re-locking the locking slot 506. This allows the movable block 405 to drive the slider 501 to reciprocate left and right, while the irregular block 1110 separates from the push rod 603.The third spring 602 returns to its original state, causing the irregularly shaped clamping block 601 to move inward and reset, re-clamping the placement block 7. The irregularly shaped clamping block 601 then presses the push rod 603 downward to reset. Similarly, the patient can also, as needed, have one leg perform reciprocating flexion and extension movements while the other leg performs reciprocating lifting movements.

[0084] Example 3

[0085] Based on Example 2, such as Figure 4 , Figure 11 and Figure 12 As shown, it also includes a limiting component 12, which includes a guide sleeve 1201, a limiting frame 1202, and an eighth spring 1203. The upper left side of the support frame 1103 is symmetrically provided with guide sleeves 1201, and the number of guide sleeves 1201 is 4. The inner sides of the guide sleeves 1201 on the same side are all slidably provided with limiting frames 1202. The limiting frames 1202 are all slidably connected to the support frame 1103. The right side of the limiting frame 1202 is provided with an eighth spring 1203 between the upper right side of the support frame 1103.

[0086] It also includes an auxiliary component 13, which includes a third rotating rod 1301, a third connecting rod 1302, a contact rod 1303, and a ninth spring 1304. The third rotating rod 1301 is symmetrically rotated on the upper right side of the support frame 1103 and the lower right side of the bed 2. The upper third rotating rod 1301 is slidably engaged with the limit frame 1202. The third connecting rod 1302 is symmetrically rotated between the middle of the third rotating rods 1301 on the same side. The contact rod 1303 is symmetrically slidably mounted on the right side of the bed 2. The contact rod 1303 is in contact with the lower third rotating rod 1301 and engages with the slider 501. The ninth spring 1304 is located between the right side of the contact rod 1303 and the right side of the bed 2.

[0087] When the patient's leg is performing a reciprocating lifting motion, the first spring 502 keeps the corresponding slider 501 stationary at the far right. Slider 501 presses against contact rod 1303, causing it to move to the right. The ninth spring 1304 stretches, and contact rod 1303 presses against the lower third rotating rod 1301, causing it to rotate to the right. This, through the third connecting rod 1302, drives the upper third rotating rod 1301 to rotate to the right. The upper third rotating rod 1301 then drives the limiting frame 1202 to move to the right. The eighth spring 1203 stretches, causing the limiting frame 1202 to block the bottom of mounting block 1105, preventing it from moving downwards. This avoids the patient's leg being too heavy, causing the rope 1 to... 102 cannot pull the placement block 7 upward. When the patient's leg is performing reciprocating flexion and extension movements, the slider 501 will move back and forth. When the slider 501 moves to the left and separates from the contact rod 1303, the ninth spring 1304 returns to its original state, driving the contact rod 1303 to move to the left to reset. The contact rod 1303 separates from the lower third rotating rod 1301, and the eighth spring 1203 returns to its original state, driving the limit frame 1202 to move to the left to reset, so that the limit frame 1202 no longer blocks the bottom of the mounting block 1105. At the same time, it drives the upper third rotating rod 1301 to rotate to the left to reset. Through the third connecting rod 1302, it drives the lower third rotating rod 1301 to rotate to the left to reset.

[0088] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
