A reflecting plate is fixedly arranged on the outer side of one end of the counting trigger plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. By setting the small arm fixing component, during rehabilitation exercise, the small arm of the patient can be tied and fixed through the small arm fixing component, which is convenient for upper limb exercise. Specifically, when in use, the patient's arm passes through the rotating cylinder on the wrist training module and holds the grip with the hand, and then bends and extends the arm, and the arm can be exercised and rehabilitated through the arm training mechanism. It is convenient to use. By setting the magnetic damper, the training intensity of the arm training mechanism can be adjusted, which is convenient for different people to use.

[0019] 2. By setting the driving mechanism, the driving mechanism can drive the arm training mechanism to swing reciprocally, which can assist in exercising patients with difficulty in exerting force on the upper limb and is beneficial to the rehabilitation of the patients. During the process of the driving mechanism exercising the patient's arm by driving the arm training mechanism, the driving mechanism can drive the counting trigger plate on the counting module to swing reciprocally. When the counting trigger plate swings, the reflecting plate and the infrared induction counting probe cooperate to count the number of flexion and extension trainings of the arm. The counted number of flexion and extension trainings is finally displayed on the counter main body, which is convenient for controlling the training intensity and can avoid the situation that the rehabilitation effect is poor due to the unqualified training intensity or the arm muscle injury caused by the excessive training intensity.

[0020] 3. By setting up the wrist training module, the patient's wrist can be rotated for exercise. The patient passes the arm through the rotating cylinder and holds the handle on the wrist training module with the palm of the hand, and rotates it forward and backward with force, then the wrist can be rotated for exercise. By setting the first pressure sensor and the second pressure sensor on the wrist training module, the forward and backward rotation forces of the patient's wrist can be detected through the first pressure sensor and the second pressure sensor. The wrist rotation exercise force value is set in advance on the single-chip microcomputer controller. When the patient rotates the wrist forward for exercise, the forward rotation force value of the patient's wrist can be detected through the first pressure sensor. When the value detected by the first pressure sensor is greater than the training value set on the single-chip microcomputer controller, the single-chip microcomputer controller will control the wrist training module to rotate forward. On the contrary, when the patient rotates the wrist backward for exercise, the backward rotation force value of the patient's wrist can be detected through the second pressure sensor. When the value detected by the second pressure sensor is greater than the training value set on the single-chip microcomputer controller, the single-chip microcomputer controller will control the wrist training module to rotate backward. By setting different training force values on the single-chip microcomputer controller, the wrist training intensity can be adjusted, which is convenient for the rehabilitation department to use for upper limb exercise rehabilitation and can meet different exercise needs.

[0021] 4. When the patient's wrist is difficult to exert force, the single-chip microcomputer controller directly controls the rotation module on the wrist training module to open. Through the rotation module, the ring gear can be driven to rotate forward and backward. When the ring gear rotates forward and backward, the handle can drive the patient's wrist to rotate forward and backward, and the wrist of the patient can be assisted in rotating for exercise, which is convenient for the rehabilitation department to use for upper limb exercise rehabilitation.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] An embodiment is as Figures 1-8 shown. An upper limb exerciser for the rehabilitation department includes a fixed base 1 and an elbow support seat 2 arranged on the top of the fixed base 1. First chassis 3 and second chassis 4 are symmetrically and fixedly arranged on the top of the fixed base 1. A driving mechanism 5 is arranged between the first chassis 3 and the second chassis 4. The top of the driving mechanism 5 is meshed with an arm training mechanism 6. Magnetic dampers 7 are symmetrically and fixedly connected to both sides of the end of the arm training mechanism 6. During specific use, the patient's arm passes through the wrist training module 9 and holds the wrist training module 9 with the palm. Then, by flexing and extending the arm, the arm can be exercised and rehabilitated through the arm training mechanism 6. The training intensity of the arm training mechanism can be regulated through the magnetic dampers 7, which is convenient for different people to use. A forearm fixing assembly 8 is fixedly connected to the middle of the arm training mechanism 6 through a bracket. During rehabilitation exercises, the patient's forearm can be tied and fixed through the forearm fixing assembly 8, which is convenient for upper limb exercises. The end of the arm training mechanism 6 away from the magnetic damper 7 is fixedly connected to a wrist training module 9. A single-chip microcomputer controller 10 is fixedly arranged on the front surface of the second chassis 4. A counting module 11 is arranged in the inner cavity of the first chassis 3. The driving mechanism 5 can drive the arm training mechanism 6 to swing back and forth, which can assist in exercising patients with difficulty in exerting force on the upper limb and is beneficial to the rehabilitation of patients. During the process of the driving mechanism 5 exercising the patient's arm by driving the arm training mechanism 6, or when the patient exercises independently, the driving mechanism 5 can drive the counting trigger plate 1101 on the counting module 11 to swing back and forth. When the counting trigger plate 1101 swings, the reflection plate 1104 and the infrared induction counting probe 1102 cooperate to count the number of flexion and extension training times of the arm. The counted number of flexion and extension training times is finally displayed on the counter body 1103, which is convenient for controlling the training intensity and can avoid the situation of poor rehabilitation effect due to unqualified training intensity or arm muscle injury caused by excessive training intensity;

[0045] The wrist training module 9 includes a connecting plate member 901 fixedly arranged at one end of the arm training mechanism 6 and a rotating module 903 fixedly arranged on one side of the connecting plate member 901. A rotating cylinder 902 is rotatably connected to the middle of the connecting plate member 901 through a bearing. An annular gear 904 is fixedly sleeved on the outer side of one end of the rotating cylinder 902. Arc-shaped sliding grooves 905 are symmetrically arranged on the annular gear 904. An arc-shaped guide rod 906 is fixedly arranged in the inner cavity of the arc-shaped sliding groove 905. An arc-shaped slider 907 is slidably sleeved on the outer side of the arc-shaped guide rod 906. Return springs 908 are sleeved on the outer side of the arc-shaped guide rod 906 at both ends of the arc-shaped slider 907. A grip 909 is fixedly connected between the two arc-shaped sliders 907. First pressure sensors 910 and second pressure sensors 911 are respectively fixedly arranged at the top of the inner cavities of the two arc-shaped sliding grooves 905. During exercise, the patient's arm passes through the rotating cylinder 902 and the patient holds the grip 909 on the wrist training module 9 and rotates it forward and backward with force to finally drive the rotating cylinder 902 to rotate forward and backward, so as to perform rotational exercise on the wrist. By arranging the first pressure sensor 910 and the second pressure sensor 911 on the wrist training module 9, the first pressure sensor 910 and the second pressure sensor 911 can detect the force of the patient's wrist rotating forward and backward. The wrist rotation exercise force value is set in advance on the single-chip microcomputer controller 10. When the patient performs forward rotation exercise on the wrist, the first pressure sensor 910 can detect the forward rotation force value of the patient's wrist. When the value detected by the first pressure sensor 910 is greater than the training value set on the single-chip microcomputer controller 10, the single-chip microcomputer controller 10 will control the rotating module 903 on the wrist training module 9 to drive the annular gear 904 and the rotating cylinder 902 to rotate forward. On the contrary, when the patient performs backward rotation exercise on the wrist, the second pressure sensor 911 can detect the backward rotation force value of the patient's wrist. When the value detected by the second pressure sensor 911 is greater than the training value set on the single-chip microcomputer controller 10, the single-chip microcomputer controller 10 will control the rotating module 903 on the wrist training module 9 to drive the annular gear 904 and the rotating cylinder 902 to rotate backward. By setting different training force values on the single-chip microcomputer controller 10, the training intensity of the wrist can be adjusted, which is convenient for the rehabilitation department to carry out upper limb exercise rehabilitation. It can meet different exercise needs. When the patient's wrist is difficult to exert force, the single-chip microcomputer controller 10 directly controls the rotating module 903 on the wrist training module 9 to open. The rotating module 903 can assist in driving the annular gear 904 and the rotating cylinder 902 to rotate forward and backward. When the annular gear 904 and the rotating cylinder 902 rotate forward and backward, they can drive the patient's wrist to rotate forward and backward through the grip 909, and can perform auxiliary rotational exercise on the patient's wrist, which is convenient for the rehabilitation department to carry out upper limb exercise rehabilitation.

The rotation motor 9032 can drive the driving gear A9033 to rotate. When the driving gear A9033 rotates, it can drive the annular gear 904 and the rotating cylinder 902 to rotate.

[0048] As a further embodiment of the above invention: The elbow support seat 2 is set as an arc-shaped structure, and rubber bumps 12 are fixedly arranged at equal intervals inside the elbow support seat 2. The elbow support seat 2 can support the patient's elbow. The rubber bumps 12 are arranged at equal intervals, which can not only improve the comfort of the elbow but also play a certain anti-slip role, avoiding the elbow from sliding during exercise and facilitating arm exercise.

[0049] As a further embodiment of the above invention: The driving mechanism 5 includes a driving motor 501 fixedly installed on one side of the inner cavity of the second chassis 4. The end of the output shaft of the driving motor 501 is fixedly connected with a driving rod 502. Two groups of driving gears B503 are fixedly sleeved on the outer side of the driving rod 502. The driving motor 501 on the driving mechanism 5 can drive the driving gears B503 to rotate forward and backward through the driving rod 502. When the driving gears B503 rotate forward and backward, through the driven gear 602, it can drive the arm training mechanism 6 to swing reciprocally, assisting the exercise of patients with difficulty in exerting force on the upper limbs and being beneficial to the recovery of patients.

[0050] As a further embodiment of the above invention: The driving rod 502 is rotatably installed between the first chassis 3 and the second chassis 4 through a bearing.

The connecting plate member 901 is fixedly connected to one end of the two training swing arms 603. When the driving gear B503 rotates forward and backward, the arm training mechanism 6 can be driven to swing reciprocally through the driven gears 602, and auxiliary exercise can be carried out for patients who have difficulty exerting force in the upper limbs.

[0052] As a further embodiment of the above invention: There are two sets of magnetic dampers 7, and the two sets of magnetic dampers 7 are respectively fixedly installed on one side of the inner cavity of the first chassis 3 and one side of the inner cavity of the second chassis 4, and the magnetic dampers 7 are fixedly connected to one end of the rotating column 601. The training intensity of the arm training mechanism can be regulated through the magnetic dampers 7, which is convenient for different groups of people to use.

[0053] As a further embodiment of the above invention: The forearm fixing assembly 8 includes an arc-shaped kit 801 fixedly arranged between the two training swing arms 603. Binding straps 802 are equidistantly arranged on the arc-shaped kit 801. During rehabilitation exercise, the forearm is placed in the arc-shaped kit 801, and then the forearm can be bound and fixed through the binding straps 802, which is convenient for upper limb exercise.

[0054] As a further embodiment of the above invention: The counting module 11 includes a counting trigger plate 1101 fixedly arranged at one end of the driving rod 502, an infrared induction counting probe 1102 fixedly arranged on one side of the inner cavity of the first chassis 3, and a counter main body 1103 fixedly installed on the outer surface of the first chassis 3. A reflecting plate 1104 is fixedly arranged on the outer side of one end of the counting trigger plate 1101. During the process of the driving mechanism 5 exercising the patient's arm by driving the arm training mechanism 6, the driving mechanism 5 can drive the counting trigger plate 1101 on the counting module 11 to swing reciprocally. When the counting trigger plate 1101 swings, the reflecting plate 1104 and the infrared induction counting probe 1102 cooperate to count the number of flexion and extension trainings of the arm. The counted number of flexion and extension trainings is finally displayed on the counter main body 1103, which is convenient for controlling the training intensity and can avoid the situation that the rehabilitation effect is poor due to the unqualified training intensity or the arm muscle injury caused by the excessive training intensity.

[0055] During use: Pass the arm through the wrist training module 9, place the elbow in the elbow support seat 2, hold the wrist training module 9 with the palm, then place the forearm in the arc-shaped kit 801, and fix the forearm by the binding strap 802. After the forearm is fixed by binding, flex and extend the arm, and the arm can be exercised and rehabilitated by the arm training mechanism 6. The training intensity of the arm training mechanism can be adjusted by the magnetic damper 7, which is convenient for different people to use. When the upper limb of the patient is difficult to exert force, control the driving mechanism 5 to rotate forward and backward automatically. When the driving mechanism 5 rotates forward and backward, it can drive the arm training mechanism 6 to swing back and forth, and can assist in exercising the patients with difficulty in exerting force in the upper limb, which is beneficial to the rehabilitation of the patients;

[0056] During the process of the driving mechanism 5 exercising the patient's arm by driving the arm training mechanism 6, or when the patient exercises independently, the driving mechanism 5 can drive the counting trigger plate 1101 on the counting module 11 to swing back and forth. When the counting trigger plate 1101 swings, the reflecting plate 1104 and the infrared induction counting probe 1102 can be used in cooperation to count the number of flexion and extension training of the arm. The counted number of flexion and extension training is finally displayed on the counter main body 1103, which is convenient for controlling the training intensity and can avoid the situation of poor rehabilitation effect due to unqualified training intensity or arm muscle injury caused by excessive training intensity;

[0057] During exercise, the patient passes their arm through the rotating cylinder 902 and holds the grip 909 on the wrist training module 9 with their hand, applying force to rotate it forward and backward, ultimately driving the rotating cylinder 902 to rotate forward and backward, thus enabling wrist rotation exercise. By setting the first pressure sensor 910 and the second pressure sensor 911 on the wrist training module 9, the force of the patient's wrist rotating forward and backward can be detected through the first pressure sensor 910 and the second pressure sensor 911. The wrist rotation exercise force value is preset on the single-chip microcomputer controller 10. When the patient performs forward wrist rotation exercise, the force value of the patient's forward wrist rotation can be detected through the first pressure sensor 910. When the value detected by the first pressure sensor 910 is greater than the training value set on the single-chip microcomputer controller 10, the single-chip microcomputer controller 10 will control the rotation module 903 on the wrist training module 9 to drive the annular gear 904 and the rotating cylinder 902 to rotate forward. Conversely, when the patient performs backward wrist rotation exercise, the force value of the patient's backward wrist rotation can be detected through the second pressure sensor 911. When the value detected by the second pressure sensor 911 is greater than the training value set on the single-chip microcomputer controller 10, the single-chip microcomputer controller 10 will control the rotation module 903 on the wrist training module 9 to drive the annular gear 904 and the rotating cylinder 902 to rotate backward. By setting different training force values on the single-chip microcomputer controller 10, the training intensity of the wrist can be regulated, facilitating the use of upper limb exercise rehabilitation in the rehabilitation department, meeting different exercise needs. When the patient's wrist has difficulty exerting force, the single-chip microcomputer controller 10 directly controls the rotation module 903 on the wrist training module 9 to turn on. Through the rotation module 903, it can assist in driving the annular gear 904 and the rotating cylinder 902 to rotate forward and backward. When the annular gear 904 and the rotating cylinder 902 rotate forward and backward, they can drive the patient's wrist to rotate forward and backward through the grip 909, enabling assisted rotation exercise of the patient's wrist.
