Description

Technical Field

[0001] This utility model relates to the field of training equipment technology, and in particular to a magnetic resistance type upper and lower limb linkage training device. Background Technology

[0002] Magnetoresistive limb training equipment primarily generates a magnetic field using permanent magnets or electromagnets. When the moving parts of the equipment (such as flywheels, shafts, etc.) move within this magnetic field, they cut magnetic field lines, generating eddy currents. According to Lenz's law, these eddy currents produce an induced magnetic field in the opposite direction to the original magnetic field, thus creating resistance that opposes the movement of the moving parts. This resistance becomes the force that needs to be overcome during limb training. By adjusting the magnetic field strength, the relative position of the moving parts to the magnetic field, or the speed of movement, the magnitude of the eddy currents can be changed, thereby adjusting the resistance to suit the needs of different trainees.

[0003] Magnetic resistance limb training devices are generally suitable for patients whose limb function is limited due to fractures, muscle strains, ligament injuries, etc. In the later stages of rehabilitation, these devices can be used for progressive strength training and joint range of motion training. By precisely adjusting the resistance, it is possible to gradually increase the resistance from a low level according to the patient's recovery progress, avoiding overtraining and secondary injury. This helps patients safely and effectively restore limb strength and motor function. For patients with conditions such as arthritis and stroke sequelae, magnetic resistance limb training devices can provide them with gentle and adjustable exercise methods. For arthritis patients, they can perform appropriate limb activities without increasing the burden on the joints, which helps maintain joint flexibility and muscle strength. For stroke sequelae patients, it helps improve limb motor control and muscle atrophy, and promotes the recovery of nerve function.

[0004] Existing upper and lower limb linkage training devices have many shortcomings. On the one hand, most devices use traditional electric drive, which not only increases the cost and energy consumption of the equipment, but also leads to malfunctions due to power failures, lacking sustainability in energy use. Furthermore, existing devices provide insufficient protection for joints during exercise, and prolonged training can easily cause injuries to the knees, ankles, and other joints. On the other hand, some devices have fixed structures, making it impossible to adjust the seat position and the angle of the training components according to different body types and conditions of trainees. This makes it difficult for trainees to find a comfortable training posture, affecting training effectiveness and experience, especially for wheelchair users and other special groups, making it difficult to meet their needs.

An adjustment frame 4 is snapped onto the inner side of the protective frame 2 for installing a handle 6. The device includes an upper limb training handle that can be rotated and adjusted to suit the needs of different trainees. It can also be used for upper limb training by wheelchair users. The above structure is existing technology and therefore will not be described in detail. The outer side wall of the sprocket teeth contacts the second sprocket belt 5.

The inner walls of the front and rear sides of the main body 1 are rotatably connected to the pulleys 9 via bearings. The left and right ends of the pulleys 9 are fixedly connected to the linkage columns 7. The outer side wall of the linkage column 7 is fixedly connected to the foot pedal 8. The inner walls of the front and rear sides of the main body 1 are rotatably connected to the rotating column 10 via bearings. The rotating column 10 is fixedly connected to the magnetic reluctance generator wheel 11, which generates electrical energy by rotating. It converts the mechanical energy of the trainee's movement into electrical energy and transmits it to the storage battery 111 through wires for storage, providing sustainable energy for the trainer. The bottom inner wall of the main body 1 is fixedly connected to the storage battery 111.

[0026] Reference Figures 2-4A frosted pad is fixedly connected to the top outer wall of the foot pedal 8. The magnetic reluctance generator wheel 11 includes brushes, a commutator, a stator, and a rotor. It is composed of a stator, a rotor, a commutator, and brushes. The stator generates a magnetic field, the rotor generates an induced electromotive force, the commutator converts alternating current to direct current, and the brushes contact the commutator to draw out the current. The above structure is existing technology and therefore will not be described in detail. The magnetic reluctance generator wheel 11 is electrically connected to the battery 111 via wires. The first sprocket belt 3 contacts the side outer wall of the pulley 9. The front and rear inner walls of the adjustment frame 4 are rotatably connected to the upper limb training handle via bearings. The second sprocket belt 5 contacts the side outer wall of the upper limb training handle.

[0027] Reference Figures 3-4 The adjustment mechanism 12 includes a seat frame 121, which is slidably connected to the front and rear outer walls of the base frame 101. A seat plate 122 is fixedly connected to the top outer wall of the seat frame 121, serving as a support structure for the seat plate 122. The seat plate 122 can slide back and forth on the base frame 101 to adjust the seat position and meet the sitting posture needs of different trainees. Positioning rollers 123 and lower rollers 124 are rotatably connected to the front and rear inner walls of the seat frame 121 via bearings. A support column 125 is fixedly connected to the front inner wall of the seat frame 121. A movable plate 126 is slidably connected to the side inner wall of the support column 125. A fixing post 127 is fixedly connected to the front outer wall of the movable plate 126. A pull handle 128 is fixedly connected to the front end of the fixing post 127. A handle 128 is fixedly connected to the rear outer wall of the movable plate 126. The seat frame 1210 has a plug plate 1210. A compression spring 129 is fixedly connected to the front outer wall of the movable plate 126. The positioning roller 123 contacts the top outer wall of the base frame 101, and the lower roller 124 contacts the top inner wall of the base frame 101. The fixed column 127 passes through the front outer wall of the support column 125. The side outer wall of the handle 128 is painted with red indicator paint. By setting the red indicator paint, the trainee can see more clearly and find the operation position for adjustment. The end of the compression spring 129 away from the movable plate 126 is fixedly connected to the front inner wall of the support column 125. During the adjustment of the seat frame 121 position, it plays a reset role. When the handle 128 is released, the plug plate 1210 can be inserted into the inner wall of the base frame 101 for limiting. The plug plate 1210 is engaged with the front inner wall of the base frame 101.

[0028] Working principle: The trainee holds the upper limb training handle, causing them to perform flexion, extension, and rotational cyclic movements. Simultaneously, the trainee steps on foot pedal 8, driving the lower limbs in an elliptical trajectory, simulating human gait. This exercise aims to strengthen the upper and lower limbs, reducing pressure on the knee and ankle joints and preventing knee injury. When the handle adjustment frame 4 is rotated in the opposite direction, it can be used for upper limb training by wheelchair users. During the up-and-down training, the upper limb training handle moves the lower second sprocket belt 5, which in turn rotates the sprocket teeth. This rotation drives the first sprocket belt 3, which in turn rotates the pulley 9, which in turn rotates the magnetic reluctance generator wheel 11. When the generator wheel 11 rotates, it generates electrical energy, which is transmitted through wires to the storage battery 111 for storage. This allows the entire upper and lower limb linkage training device to be used without being plugged in. At the same time, since different trainees have different sitting postures, the fixed column 127 is moved by pulling the handle 128. The movement of the fixed column 127 moves the movable plate 126, which in turn moves the insertion plate 1210. The insertion plate 1210 moves and separates from the front inner wall of the base frame 101. Then, the seat frame 121 is moved back and forth on the base frame 101. After adjustment, the insertion plate 1210 is reinserted into the corresponding front inner wall of the base frame 101 for limiting, allowing different people to sit on the seat plate 122 in different positions to adjust the comfort.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
