Description

Technical Field

[0001] This invention relates to the field of postoperative arm training technology, specifically to a striking cushioning mechanism and a postoperative arm training device containing the mechanism. Background Technology

[0002] Following surgeries involving the arm, such as orthopedic and breast surgeries, patients are prone to functional impairments such as joint stiffness and decreased muscle strength. Scientific postoperative arm training is crucial for restoring normal limb function and preventing secondary injury. Currently, postoperative arm training for patients has significant shortcomings. Most patients rely on voluntary movement for rehabilitation, but their arm strength is weak and their range of motion is limited after surgery. Self-training makes it difficult to control the force and range of motion, resulting in poor targeting and low efficiency. Furthermore, improper force application can lead to wound traction and worsened tissue adhesions. The convenience of self-training is extremely poor, failing to meet the precise needs of postoperative rehabilitation.

[0003] Secondly, among existing auxiliary training devices, wall-mounted striking trainers are widely used due to their small footprint. However, these devices have a fatal flaw: relying on wall mounting for fixation, they are prone to loosening and wobbling after prolonged exposure to the impact force generated by the patient's strikes. This not only affects the continuity of the patient's force application during training but may also pose safety hazards. More importantly, the instability of the device directly interferes with the accurate measurement of striking force, making it impossible for medical staff to obtain the patient's true training data. This hinders the development or adjustment of personalized rehabilitation plans and severely impacts rehabilitation outcomes. Therefore, there is an urgent need to develop a postoperative arm training device that addresses these problems. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a striking buffer mechanism and a postoperative arm training device containing the mechanism, which can effectively solve the problems of inconvenient postoperative arm training and easy deviation of long-term striking training devices in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a striking buffer mechanism, including a trainer, and further comprising: The arm assistive assembly includes two protective gears slidably disposed on both sides of the trainer, with an assistive wrap plate rotatably mounted on both sides of each protective gear; The impact reinforcement assembly includes a rotating frame rotatably mounted in a trainer, an impact block being movably mounted at a distance on the rotating frame, and an adsorption element provided on the mounting surface of the trainer. When the impact block is impacted, the adsorption force of the adsorption element increases. The impact reinforcement assembly also includes a drive component that drives the rotating frame to rotate intermittently, and each rotation of the rotating frame drives the protective gear to reciprocate linearly once.

[0006] Furthermore, two mounting brackets are symmetrically installed on the outer walls of both sides of the trainer. A sliding plate is slidably installed on each of the two mounting brackets. A first telescopic frame is slidably installed on the sliding plate. A second telescopic frame is provided at the telescopic end of the first telescopic frame. The protective gear is installed at the telescopic end of the second telescopic frame.

[0007] Furthermore, an electric actuator is fixedly installed at the telescopic end of the first telescopic frame, and the output end of the electric actuator is fixedly connected to the side wall of the second telescopic frame.

[0009] Furthermore, a first magnet is fixedly installed in the first piston tube, and a second magnet is fixedly installed at one end of the first piston rod located in the first piston tube.

[0010] Furthermore, the driving component includes a rotating tube fixedly mounted on a rotating frame, a full gear sleeved on the rotating tube, a drive motor in the trainer, and a half gear meshing with the full gear on the output shaft of the drive motor.

[0011] Furthermore, the trainer is provided with an elastic rod, a first trigger switch is fixedly installed at the telescopic end of the elastic rod, and a pressure plate is fixedly installed at the telescopic end of the elastic rod. A second trigger switch is fixedly installed on the side wall of the elastic rod. A multi-head cam is fixedly sleeved on the rotating tube. When the multi-head cam rotates, it reciprocates to squeeze the elastic rod. When the squeezing force of the multi-head cam is at its maximum, the first trigger switch and the second trigger switch are triggered simultaneously.

[0012] Furthermore, when the first trigger switch is triggered, the first magnet and the second magnet attract each other; when the first trigger switch and the second trigger switch are triggered simultaneously, the first magnet and the second magnet repel each other.

[0013] Furthermore, the rotating frame is provided with multiple buffer slots, the striking block is disposed in the buffer slots, the buffer slots are provided with a second piston tube, a second piston rod is movably inserted into the second piston tube, the end of the second piston rod is fixedly connected to the striking block, a detector is elastically connected between the striking block and the buffer slots, an extraction tube is connected between the second piston tube and the rotating tube, an air intake tube is rotatably inserted into the mounting surface of the trainer, and a sealed bearing is connected between the air intake tube and the rotating tube.

[0014] Furthermore, the adsorption component includes a mounting ring installed in the trainer, the mounting ring having multiple suction cups, and a connecting pipe connecting the suction cups and the rotating tube.

[0015] Furthermore, the air inlet tube is provided with an air supply hole, an adjusting block is slidably provided in the air supply hole, and an adjusting hole is provided in the adjusting block.

[0018] The technical solution provided by this invention has the following advantages compared with the known prior art: By incorporating an arm-assisted component to help patients with striking training, the training becomes less strenuous. The striking blocks are constantly repositioned during training, allowing for multiple sets of comparative data to improve training accuracy. Furthermore, a striking reinforcement component is included in the trainer, which transforms the patient's striking force into reinforcement of the trainer, providing cushioning and further enhancing training precision.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] The present invention will be further described below with reference to embodiments. Example 1:

[0024] refer to Figures 1-3 A striking cushioning mechanism includes a trainer 1 and an arm assist assembly, comprising two protective gears 8 slidably disposed on both sides of the trainer 1. Two mounting brackets 3 are symmetrically mounted on the outer walls of both sides of the trainer 1. A slide plate 4 is slidably mounted on each of the two mounting brackets 3. A first telescopic frame 5 is slidably mounted on the slide plate 4. A second telescopic frame 7 is provided at the telescopic end of the first telescopic frame 5. The protective gear 8 is mounted on the telescopic end of the second telescopic frame 7. An electric push rod 6 is fixedly mounted at the telescopic end of the first telescopic frame 5. The output end of the electric push rod 6 is fixedly connected to the side wall of the second telescopic frame 7. The telescopic directions of the first telescopic frame 5 and the second telescopic frame 7 are perpendicular. An assist wrapping plate 9 is rotatably mounted on both sides of each protective gear 8. The assist wrapping plate 9 includes two telescopically connected arc-shaped plates. A strap 10 is mounted on the arc-shaped plates. A handle is mounted on one end of the assist wrapping plate 9 near the trainer 1, and a cushioning plate is also elastically connected to one end of the assist wrapping plate 9.

[0025] like Figure 1As shown, the protective gear 8 can be adjusted to move forward and backward and left and right through the first telescopic frame 5 and the second telescopic frame 7. At the same time, an electric push rod 6 is set at the end of the first telescopic frame 5, which can simulate the action of punching.

[0026] In addition, the height and initial horizontal position of the protective gear 8 can be adjusted by the slide plate 4, so that it can be suitable for patients of different heights, and can also be adapted to some patients with mobility impairments.

[0027] The protective gear 8 is equipped with a support wrapping plate 9, which includes two curved plates. The spacing between the two curved plates can be adjusted to accommodate customers of different body types.

[0028] When in use, the patient's arm is tied with strap 10, the patient holds the handle and makes a fist, and the impact force on the patient's arm is reduced by the buffer plate, similar to boxing gloves, but without the need to take them off, making it more convenient.

[0029] refer to Figure 5 and Figure 6 The top of the second telescopic frame 7 is provided with a first piston tube 11. A first piston rod 12 is movably inserted into one end of the first piston tube 11 near the protective gear 8, and a force-generating spring 13 is sleeved on the first piston rod 12. A rotating linkage frame is provided on the top wall of the protective gear 8. The end of the first piston rod 12 is connected to the rotating linkage frame. A first magnet 30 is fixedly installed in the first piston tube 11, and a second magnet 31 is fixedly installed at one end of the first piston rod 12 located in the first piston tube 11. The driving component includes a rotating tube 18 fixedly installed on the rotating frame 20. A full gear is sleeved on the rotating tube 18. The trainer 1 is provided with a drive motor, and a half gear meshing with the full gear is provided on the output shaft of the drive motor. The gear and training device 1 are equipped with an elastic rod 26. A first trigger switch 27 is fixedly installed on the telescopic end of the elastic rod 26, and a pressure plate 29 is fixedly installed on the telescopic end of the elastic rod 26. A second trigger switch 28 is fixedly installed on the side wall of the elastic rod 26. A multi-head cam 25 is fixedly sleeved on the rotating tube 18. When the multi-head cam 25 rotates, it reciprocates to squeeze the elastic rod 26. When the squeezing force of the multi-head cam 25 is at its maximum, the first trigger switch 27 and the second trigger switch 28 are triggered simultaneously. When the first trigger switch 27 is triggered, the first magnet 30 and the second magnet 31 attract each other. When the first trigger switch 27 and the second trigger switch 28 are triggered simultaneously, the first magnet 30 and the second magnet 31 repel each other.

[0030] like Figure 4 and Figure 5 As shown, the drive motor drives the half gear to rotate, and the half gear and the full gear periodically transmit power, causing the rotating frame 20 to rotate at a certain angle. This achieves the purpose of hitting different striking blocks 2 each time, obtaining different sets of data. This allows for more accurate acquisition of the patient's recovery data, thereby enabling the development of a better training program.

[0031] At the same time, the rotation of the rotating frame 20 will also drive the multi-head cam 25 to rotate. The multi-head cam 25 is composed of multiple concentric cams, and the number of cams is the same as the number of striking blocks 2. That is, each time the striking block 2 is replaced, one of the cams in the multi-head cam 25 will be driven to press against the elastic rod 26 (e.g., Figure 7 As shown), when the compression begins, only the first trigger switch 27 is triggered. At this time, the first magnet 30 and the second magnet 31 attract each other, that is, the first piston rod 12 moves into the first piston tube 11, pulling the patient's arm to bend. Then the elastic rod 26 is compressed until the second trigger switch 28 is triggered. At this time, the striking block 2 completes the position change. At the same time, the first magnet 30 and the second magnet 31 repel each other, which, together with the force spring 13, assists the patient in punching.

[0032] Since both the first magnet 30 and the second magnet 31 are electromagnets, the intensity of magnetic repulsion and attraction can be controlled by adjusting the output power of the magnet's path. In this way, the force of the assistive patient's punch can be changed by adjusting the degree of compression of the force-generating spring 13 when the first magnet 30 and the second magnet 31 repel and attract each other. Example 2:

[0033] refer to Figure 7 and Figure 8 To improve the overall stability of the trainer 1, a striking reinforcement component is added, including a rotating frame 20 rotatably mounted in the trainer 1. A striking block 2 is movably mounted at a distance on the rotating frame 20. An adsorption component is provided on the mounting surface of the trainer 1, including a mounting ring 14 mounted in the trainer 1. Multiple suction cups 15 are provided on the mounting ring 14, and a connecting pipe 19 connects the suction cups 15 and the rotating tube 18. When the striking block 2 is impacted, the adsorption force of the adsorption component increases. Multiple buffer grooves 21 are provided on the rotating frame 20, and the striking block 2 is placed in the buffer grooves 21. A second piston tube 22 is provided in the buffer grooves 21, and a second piston rod 23 is movably inserted into the second piston tube 22. The end of the plunger 23 is fixedly connected to the striking block 2. A detector 36 is elastically connected between the striking block 2 and the buffer groove 21 (the detector 36 detects the striking force, and comparative data is obtained by using different striking blocks 2 to improve the accuracy of training). An extraction tube 24 is connected between the second piston tube 22 and the rotating tube 18. An air intake tube 16 is rotatably inserted into the mounting surface of the trainer 1. A sealed bearing 17 is connected between the air intake tube 16 and the rotating tube 18. An air supply hole 32 is provided on the air supply hole 16. An adjusting block 33 is slidably provided in the air supply hole 32, and an adjusting hole 34 is provided in the adjusting block 33. The adjusting hole 34 is T-shaped. A reset rod 35 is connected between the adjusting block 33 and the inner wall of the connecting tube 19. The striking reinforcement assembly also includes a driving component that drives the rotating frame 20 to rotate intermittently. Each rotation of the rotating frame 20 drives the protective gear 8 to reciprocate linearly once.

[0034] like Figure 7 As shown, each time the punch is thrown, the striking block 2 moves into the buffer groove 21, squeezing the second piston rod 23 into the second piston tube 22. The second piston tube 22 draws air from the suction pipe 16 through the extraction pipe 24, and the suction pipe 16 draws air from the mounting ring 14, thereby drawing air from the suction cup 15 and increasing the suction force. The second piston tube 22 is connected to an air outlet, and the rotating frame 20 is equipped with an exhaust port. When the second piston rod 23 rebounds, the second piston tube 22 discharges the drawn air through the air outlet and exhaust port. Both the extraction pipe 24 and the air outlet are equipped with one-way valves.

[0035] When the amount of air that can be adsorbed at suction cup 15 is insufficient, such as Figure 9 As shown, the adjusting block 33 slides under the action of the adsorption force, and the air suction pipe 16 is temporarily connected to the external space through the adjusting hole 34. At this time, the air suction pipe 16 draws out a part of the external air for the extraction pipe 24 to suck up, so as to maintain the overall stability of the impact reinforcement component.

[0036] The second piston tube 22 is equipped with a spring. This arrangement of the second piston rod 23 and the second piston tube 22 not only serves to reinforce the piston but also to provide a buffer, preventing the impact from feeling too hard.

[0037] A postoperative arm training device employs the aforementioned impact buffer mechanism.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
