Description
TECHNICAL FIELD
[0001] The utility model relates to upper limbs rehabilitation training device technical field more specifically, it relates to an upper limbs rehabilitation training device. BACKGROUND
[0002] In the prior art of upper limbs rehabilitation training, the existing rehabilitation training device has many shortcomings, which seriously affect the effect of rehabilitation training, the applicability of the equipment and the safety of the user.
[0003] Firstly, the conventional upper limbs rehabilitation training device generally has the problems of simple structure and single function. These devices can usually only realize movement in a single direction or limited angle, and cannot meet the needs of multi-angle and multi-directional bending of the upper arm and forearm in upper limbs rehabilitation training. For example, some equipment can only realize the forward and backward swinging of the arm, but cannot rotate or move laterally, that is, cannot drive the forearm to bend, which seriously restricts the comprehensiveness and effectiveness of rehabilitation training. For patients who need to recover the function of the upper limbs in all directions, the training effect of such equipment is often unsatisfactory, which may lead to slow rehabilitation progress, and even some muscle groups may atrophy due to lack of exercise. In addition, the single movement mode is also easy to make the patient feel boring and tedious during training, which reduces the training enthusiasm and affects the rehabilitation effect.
[0004] Secondly, although some improved devices in the prior art introduce a clamping mechanism driven by a motor to try to clamp the upper arm and forearm of the user separately, this design still has obvious defects. The most prominent problem is that these devices cannot flexibly adjust the clamping force according to the body characteristics of different users. As we all know, the body characteristics of each person, such as body type, body fat rate, muscle density, etc. are significantly different. For example, the circumference and softness of the arm of a lean user and a fat user may be very different. If a uniform clamping force is used, the lean user may feel too tight or even painful, while the fat user may not be clamped firmly enough, which may fall off. This "one-size-fits-all" design not only affects the comfort of the user, but also may have a negative impact on the effect of rehabilitation training. More importantly, since the trigger mechanism of the emergency stop protection device cannot be adjusted according to the body characteristics of the user, the device may not be stopped in time in an emergency, which may pose a potential safety hazard.
[0005] In addition, although some more advanced devices introduce adjustable clamping force and triggering mechanism to try to solve the problem of individual differences, there are still obvious deficiencies in the structural design of these devices, the main problem is that these adjustable structures are often too simple, lack effective fixing and locking mechanism, and the movement of the device inevitably produces vibration and movement during the rehabilitation training process, which may cause the structure of the adjusted triggering mechanism to shift or deform, resulting in changes in the triggering threshold; this not only affects the accuracy and consistency of the training, but also may cause serious safety hazards, if the triggering mechanism suddenly fails during the clamping of the arm, the device may not stop in time in an emergency, increasing the risk of injury to the user.

[0017] (Three) beneficial effects
[0018] Compared with the prior art, the utility model provides a kind of upper limb rehabilitation training device, with following
[0019] Beneficial effects:
[0020] 1. The design of the rotating device solves the problem of single function and inability to realize multi-angle movement of traditional equipment. It includes movable frame, rotating frame and fixed frame and other components, forming a flexible movement system. The rotation of the rotating frame is realized by the rotation of the driving wheel and the driven wheel driven by the rotating motor. At the same time, the rotation of the movable frame on the rotating frame is controlled by the movable motor. This design not only realizes the rotation of the large arm, but also independently controls the extension and retraction of the small arm, thereby realizing the all-round and multi-angle rehabilitation training of the large arm and the small arm. This multi-degree-of-freedom movement mode overcomes the limitation of traditional equipment that can only move in a single direction, providing a more comprehensive and effective rehabilitation training program for patients. At the same time, the reduction gear box equipped with the equipment ensures the smoothness of the movement, avoiding sudden movements that may cause discomfort or harm to the patient, improving the safety and comfort of the training.
[0021] 2. The introduction of the protection device solves the problem of inability to adjust the clamping force and trigger mechanism according to individual differences. It includes shaft sleeve, control sleeve, shaft rod, clamping mechanism, movable slot, push spring, movable block, limiting slot, screw sleeve, limiting block and limiting frame and other components. Through this design, the equipment can flexibly adjust the clamping force and the sensitivity of the trigger mechanism according to the body characteristics of the patient. The rotation of the control sleeve can change the compression degree of the push spring, thereby adjusting the difficulty of the limiting frame sliding out of the limiting slot, which directly affects the trigger sensitivity of the clamping mechanism. This adjustable design not only improves the adaptability of the equipment to patients of different body types, but also greatly enhances the safety of the training process. For example, for patients with thin body type or weak muscle strength, the trigger threshold can be reduced to ensure that the equipment can be stopped in time in case of abnormal situations. For patients with a fat body type or strong muscle strength, the trigger threshold can be appropriately increased to avoid false triggering affecting the training effect. This personalized adjustment mechanism greatly improves the application range and safety of the equipment.
[0022] 3. The design of the reinforcing mechanism solves the problem of insufficient stability of the adjustment structure. It includes adapter plate, adapter rod, lock sleeve, lock rod, lock slot and adapter hole and other components. This design ensures the stability of the adjusted structure through multiple locking mechanisms. The cooperation of the adapter plate and the adapter rod allows the operator to easily unlock when adjustment is needed, and to firmly lock by rotating the adapter plate after adjustment is completed. The design of the lock sleeve and the lock rod further enhances the locking effect, preventing the control sleeve from shifting during equipment operation due to vibration or movement. The setting of the adapter spring provides pre-tightening force to ensure that the locking mechanism is always in a stable state. This multiple locking mechanism effectively solves the problem of loose adjustment structure in traditional equipment, ensuring the stability and reliability of the trigger mechanism during training. Even during long training, the equipment can maintain the initial adjusted state, ensuring the consistency and safety of the training. BRIEF DESCRIPTION OF DRAWINGS
