[0002] In modern society, the health problem of children always attracts the heartstrings of every parent and all circles of society, especially when children suffer from arm injury, the problem is more prominent. After arm injury, due to long-term braking and lack of necessary activities, the arm muscles of children often atrophy, and the joints can become stiff. These complications not only bring many inconveniences to the daily life of children, but also have a profound impact on their learning and development. Therefore, after the arm has recovered certain activity ability, following the professional guidance of medical staff, scientific and appropriate arm rehabilitation exercise plays a crucial role in promoting the recovery of the arm function of children and reducing the occurrence of complications. However, although there are some devices and tools for arm exercise of children on the market, these products can indeed help children to perform arm rehabilitation exercise to some extent, but they still have some deficiencies in design and use. Specifically, the existing arm exercise devices mostly focus on the realization of exercise function, and ignore the psychological characteristics and needs of children. These devices are often rather dull and lack of interactivity and interest when used, and it is difficult to attract the attention of children for a long time and stimulate their exercise enthusiasm. In this way, not only the continuity and regularity of exercise are affected, but also the children may develop resistance to exercise, thereby reducing the effect of exercise.

At the same time, the control line of the storage module is connected to the control line of the microprocessor to form a control path. The storage module is used to store preset programs and parameters, such as the strobe mode of the light strip and the playback content of the speaker.

[0023] The beneficial effects of this improvement are as follows: When the child pushes the seat to the trigger position, i.e., the photoelectric sensor setting position, the photoelectric sensor detects the change in light intensity and outputs an electrical signal. After receiving the electrical signal from the photoelectric sensor, the microprocessor controls the level state of the interface circuit according to the preset program, causing the light strip to start flashing to provide visual ambiance encouragement. At the same time, the microprocessor also controls the input signal of the audio amplifier circuit, causing the speaker to start playing preset audio content to provide sound ambiance encouragement. The storage module provides the necessary program and parameter support throughout the process.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0035] like Figures 1-5As shown, a children's rehabilitation arm exercise device includes a seat 1 and armrest seats 2 disposed on both sides of the seat 1. The armrest seats 2 are equipped with a microprocessor 3, a power supply 4, a storage module 5, and a speaker 6. A movable groove 7 is formed in the armrest seats 2, and a photoelectric sensor 8, a spring 9, a push seat 10, a fixed seat 11, an adjusting seat 12, and a screw 13 are disposed in the movable groove 7. The transmitter and receiver of the photoelectric sensor 8 are respectively disposed opposite to each other on both sides of the inner wall of the movable groove 7, so that the sensor output signal is triggered when the push seat 10 moves and blocks the light beam. A handle 15 is provided at the top of the push seat 10 for easy gripping by children. An LED strip 16 and scale lines 17 are provided on the armrest seats 2. The power supply 4, storage module 5, speaker 6, and light... The electrical sensor 8 and the light strip 16 are both electrically connected to the microprocessor 3 via wires to form a complete control circuit. When the child grips the handle 15, it moves the push seat 10 to the trigger position, which is the effective exercise position. The activation of the atmosphere function encourages the child, increasing the interactivity and fun of the exercise, attracting the child's attention, and stimulating their enthusiasm for exercise. The moving groove 7 is located at the middle of the top of the armrest 2 along its length. Springs 9 are installed on both sides of the inner end of the moving groove 7. The rear ends of the springs 9 are connected to the front walls of the push seat 10, which is movably located at the rear end of the moving groove 7. The front ends of the springs 9 are connected to the rear walls of the adjustment seat 12, which is movably located at the front end of the moving groove 7. When the child grips the push seat 10... When the top handle 15 moves the push seat 10 forward, it compresses the spring 9. When the force applied to the push seat 10 is released, the push seat 10 can move backward and reset under the rebound force of the spring 9. Both sides of the bottom end of the push seat 10 are provided with pulleys 14. The presence of pulleys 14 on both sides of the bottom end of the push seat 10 increases the smoothness of the push seat 10's forward and backward movement in the moving groove 7. The fixed seat 11 is located in the moving groove 7 near the adjusting seat 12. The fixed seat 11 is connected to one end of the screw 13, and the other end of the screw 13 passes through the adjusting seat 12 and the armrest seat 2 and is connected to the knob 19 located on the outside. The outer thread of the screw 13 is compatible with the inner thread of the adjusting seat 12. By rotating the knob 19, the screw 13 is rotated, adjusting the position. The seat 12 rotates with the screw 13, allowing for forward and backward displacement adjustment within the moving groove 7. This compresses or releases the spring 9, enabling adjustment of the arm exercise resistance according to the rehabilitation progress. A triangular guide block 18 is located on the outer upper end of the adjusting seat 12, while a scale line 17 is positioned on the top wall of the armrest seat 2 at the end of the guide block 18. This scale line 17 indicates the distance the adjusting seat 12 has moved, and the presence of the scale line 17 and guide block 18 allows rehabilitation staff to easily determine the current resistance value by reading and confirming the distance the adjusting seat 12 has moved. The light strip 16 is located on both sides of the top of the armrest seat 2.Furthermore, the input terminal of the light strip 16 is connected to the output terminal of the microprocessor 3 via a wire to form a control path. The microprocessor 3 controls the level state of the interface circuit to realize the on / off and flashing of the light strip 16. The light strip 16, when lit and flashing under ambient lighting conditions, provides visual encouragement and support for children. The output terminal of the photoelectric sensor 8 is connected to the input terminal of the microprocessor 3 via a wire to form a signal transmission path. The audio output terminal of the microprocessor 3 is connected to the input terminal of the speaker 6 via an audio amplification circuit to form an audio transmission path. The data bus of the storage module 5 is connected to the data bus of the microprocessor 3 to form a data transmission path. Simultaneously, the control line of the storage module 5 is connected to the control line of the microprocessor 3 to form a control path. The storage module 5 stores preset programs and parameters, such as the flashing mode of the light strip 16 and the playback content of the speaker 6. By pushing... When the child pushes seat 10, it reaches the trigger position, i.e., the setting position of photoelectric sensor 8. After detecting the change in light intensity, photoelectric sensor 8 outputs an electrical signal. Upon receiving the electrical signal from photoelectric sensor 8, microprocessor 3, according to a preset program, controls the level state of the interface circuit, causing light strip 16 to flash, providing visual ambiance encouragement. Simultaneously, microprocessor 3 also controls the input signal of the audio amplification circuit, causing speaker 6 to play preset audio content, providing auditory ambiance encouragement. Storage module 5 provides necessary program and parameter support throughout the process. The positive terminal of power supply 4 is connected to the positive terminals of each component via wires, while the negative terminal of power supply 4 is connected to the negative terminals of each component via wires, forming a stable DC voltage supply path. The establishment of power supply 4 provides a stable DC voltage for the entire system, ensuring continuous operation of each component.

[0036] The working principle of this utility model is as follows: When a child sits on the seat 1 with both hands on the armrests 2 on either side, they only need to hold the handles 15 to push the push seat 10 forward in the moving slot 7 to extend their arms. Once the push seat 10 moves to a trigger position detectable by the photoelectric sensor 8, it will effectively exercise the child. At this time, the photoelectric sensor 8 will detect the change in light intensity and output an electrical signal. After receiving the electrical signal from the photoelectric sensor 8, the microprocessor 3, according to a preset program, controls the level state of the interface circuit, causing the light strip 16 to flash, providing visual encouragement. Simultaneously, the microprocessor 3 also controls the input signal of the audio amplification circuit, causing the speaker 6 to play preset audio content, providing auditory encouragement. The storage module 5 provides necessary program and parameter support throughout the process. When the push seat is released... When the force is applied to the push seat 10, the push seat 10 returns to its original position under the rebound force of the spring 9, which allows the child's arm to flex and extend repeatedly, thus achieving arm rehabilitation exercises. The presence of pulleys 14 on both sides of the bottom of the push seat 10 increases the smoothness of the push seat 10's forward and backward movement in the moving groove 7. By rotating the knob 19, the screw 13 rotates, and the adjusting seat 12 rotates with the screw 13, adjusting its forward and backward movement in the moving groove 7, thereby compressing or releasing the spring 9. This allows for adjustment of the arm exercise resistance according to the rehabilitation process. With the establishment of the scale line 17 and the indicator block 18, when the moving adjusting seat 12 adjusts the arm exercise resistance, the indicator block 18 indicates different positions of the scale line 17, making it easy for rehabilitation care personnel to read and confirm the movement distance of the adjusting seat 12, and thus determine the current resistance value.
