[0002] The number of stroke patients in my country is increasing year by year. Even after treatment, they often have upper and lower limb movement disorders. Some patients with lower limb movement disorders can gradually walk on their own through walking training for rehabilitation training, while upper limb movement disorders require rehabilitation training through professional training equipment. The current upper limb rehabilitation training equipment is complex in structure and large in size, and needs to be carried out in a special training venue, which limits the application of patients. Moreover, the current training equipment often only has one of the functions of active training, passive training, resistance training, and power training. It has a single function and cannot test and evaluate the effectiveness and effect of the patient's training, making it difficult to find the best rehabilitation training plan. In addition, the current passive upper limb rehabilitation training provides weak protection for patients when the equipment fails during training. Since these patients have poor neurological perception, they may be injured by large-scale forced movement during training. Summary of the invention

[0018] In order to more fully explain the implementation of the present invention, the implementation examples of the present invention are provided. These implementation examples are merely elaborations of the present invention and do not limit the scope of the present invention.

[0020] As shown in the attached drawings, an upper limb rehabilitation trainer that integrates assessment testing and active and passive training includes a base plate 1, on which a guide rail 2 in the front-to-back direction is fixedly installed, and a guide rail 3 in the left-to-right direction is installed on the guide rail in the front-to-back direction for sliding forward and backward. The guide rails in the front-to-back direction are two parallel rails, and the two ends of the left-to-right direction guide rails are slidably installed on the two guide rails in the front-to-back direction. A slider 4 is installed on the left-to-right direction guide rails, and a handle 5 and a support hand rest 6 are installed on the slider. The handle and the support hand rest are both installed on the slider in a horizontal direction for rotation.

[0021] An infrared touch screen frame 7 is fixedly mounted on the bottom plate, and the center of the infrared touch screen frame coincides with the center of the rectangle formed by the four corners of the guide rails in the front and rear directions. The guide rails and sliders in the left and right directions are both located above the infrared touch screen frame, and a set of intelligent pull-cord drive mechanisms are respectively mounted on the bottom plates at the four corners of the infrared touch screen frame.

[0022] The intelligent pull rope driving mechanism includes a motor 11, a reel 12 is connected to the output shaft of the motor, one end of the pull rope 13 is fixed to the reel 12, a synchronous plate 10 is fixedly connected to the slider 4, the synchronous plate 10 is located below the slider, four winding columns 15 are fixedly connected to the synchronous plate, a rotating wheel is installed on the winding column, and the pull rope is passed around the rotating wheel. The four winding columns are evenly distributed on the same circumference with the center of the synchronous plate as the center of the circle, and the pull rope is connected to the Hall sensor 9 near the corresponding corner of the infrared touch screen frame after passing around the winding column. The Hall sensor is installed on the bottom plate, and the Hall sensor includes a Hall integrated board 901, the Hall integrated board is fixed on the bottom plate, the fixed shaft 903 is fixedly connected to the Hall integrated board, the magnet 902 is rotatably connected to the fixed shaft 903, and the pull rope is fixedly connected to the magnet. This Hall sensor is a prior art, the pull rope drives the magnet to rotate, and after the magnet rotates, the Hall integrated board can detect the position of the magnet, thereby determining the angle direction of the pull rope, and then calculating the position of the synchronous belt plate. A transition fixed pulley 14 is installed at the pull rope between the Hall sensor and the reel, and the pull rope is passed around the transition fixed pulley.

[0023] The lower part of the synchronization plate 10 is inductively coupled to the infrared touch screen frame. The pull rope 13 passes through the dynamometer 8 from the reel to the middle of the Hall sensor. The force measuring end of the dynamometer 8 is provided with a rope threading hole 801. The pull rope passes through the rope threading hole. The dynamometer is fixedly connected to the mobile drive device. The mobile drive device is a lead screw 802. The lead screw is connected to the lead screw drive motor 803. The lead screw is equipped with a lead screw slider. The dynamometer is fixedly connected to the lead screw slider. The dynamometer is a digital display dynamometer. The pull rope first passes through the transition fixed pulley and then the winding column. The dynamometer is installed between the reel and the transition fixed pulley. The function of the dynamometer is to detect the tension of the pull rope to ensure that the tension of the pull rope is always within the set range during the operation of the equipment. If the tension of the pull rope does not meet the requirements, the tension of the pull rope is adjusted by driving the dynamometer to move by the lead screw. The tension of the pull rope is within the set range to ensure the normal operation of the equipment and the normal detection of the position.

[0024] The motor 11, infrared touch screen frame 7, dynamometer 8, and mobile drive device are all connected to the controller.

[0025] When using this device, the patient holds the handle and places the forearm on the support hand rest to start training. During the movement, the synchronization board senses the infrared touch screen frame to determine the position of the slider, and the signal of the Hall sensor can also determine the position of the slider. The controller reads the data of the infrared touch screen frame and the Hall sensor to calibrate the position. If there is a deviation, an alarm will be issued and the motor will be immediately controlled to brake and stop moving to avoid accidental injury to the user. It effectively protects the patient. Protection is particularly important when training in passive mode.

[0026] This trainer can be used for training in passive mode, active mode, resistance mode, and power-assisted mode:

[0027] 1. In passive mode, the motor is in working state, and the motor drives the patient to perform upper limb training through the pull rope. At this time, the dynamometer is in tension state;

[0028] 2. In the resistance mode, the motor is auxiliary. The infrared touch screen frame applies the corresponding opposite force to the two motors according to the moving direction of the support hand. When the tension meter value decreases, the two motors control the rope reel to tighten the rope, so that the tension meter is maintained within the specific tension range and the tension of the rope is kept tight.

[0029] 3. In the power-assisted mode, the infrared touch screen frame is given corresponding acceleration by two specific motors according to the moving direction of the support hand rest to assist it in moving, and the other two motors maintain the tension of the rope.

[0030] 4. In active mode, turn off the motor, allow the patient to train freely, and keep the tension of the dynamometer within the set range.

[0031] After describing the implementation mode of the present invention in detail, people familiar with the technology can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention, and the present invention is not limited to the implementation mode of the examples given in the specification.
