DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1

[0029] Most of the training chairs in the prior art have simple structures and low comfort levels. They can only help the elderly whose arms can move freely to complete daily training. However, for the elderly whose arms are not easy to move, there is no way to use the training chair to complete daily rehabilitation training independently, which cannot meet the different needs of the elderly. In order to solve this technical defect in the prior art, Figure 1-Figure 4As shown, this embodiment proposes a limb function rehabilitation training chair, which can not only help the elderly with limited arm movement to quickly complete arm joint training, but also help the elderly with normal arm movement to train arm strength. A backrest assembly 2 is movably installed on the seat plate 1 of the training chair, and the backrest assembly 2 includes a backrest body movably connected to the seat plate 1. The upper end of the backrest body is provided with a headrest for protecting the cervical vertebra. During training, the headrest can support and cushion the user's cervical vertebra, thereby improving the user's comfort. The backrest assembly 2 is provided with a limb training mechanism 3 for exercising arm joints and grip strength, and the seat plate 1 is provided with a limiting auxiliary mechanism 4 for leg limiting and massage. The lower end of the seat plate 1 is provided with a height adjustment mechanism 5. When using the training chair, the height adjustment mechanism 5 is first used to adjust the seat plate 1 to a suitable height. After the user sits down, the limiting auxiliary mechanism 4 will limit and fix the legs and waist, and then the limb training mechanism 3 is used for rehabilitation training.

[0030] In order to lift and support the arms of the elderly and make the elderly's exercise posture more standardized, the present embodiment is provided with a limb training mechanism 3. Specifically, the limb training mechanism 3 includes side wall grooves 301 symmetrically opened on both sides of the backrest body, and a mounting slider 302 is slidably connected to the side wall groove 301. An electric push rod 303 for driving the mounting slider 302 to move up and down is arranged inside the side wall groove 301. A training bracket 304 is hingedly arranged on the mounting slider 302, and a micro motor 305 for driving the training bracket 304 is fixedly installed at the lower end of the mounting slider 302. A columnar airbag 306 is fixedly installed on the training bracket 304. The columnar airbag 306 is made of a rubber material whose shape can be automatically restored, and a one-way When the circulating air valve is squeezed, the air inside the columnar airbag 306 will be discharged through the exhaust hose 307 and the rectangular air nozzle 308. When the deformation is restored, the air will enter the interior of the columnar airbag 306 through the air valve. A rectangular air nozzle 308 is fixedly installed on the side of the backrest body away from the user. An exhaust hose 307 is connected between the rectangular air nozzle 308 and the columnar airbag 306. A circular air hole 309 is opened on the side of the backrest body close to the user. When the micro motor 305 is powered on, it can make the training bracket 304 rotate in a predetermined direction, so as to assist the user to complete joint activity training. The rectangular air nozzle 308 is connected to the circular air hole 309. After the air is discharged through the rectangular air nozzle 308, it will be evenly sprayed out through multiple circular air holes 309.

[0031] According to the above content, when using the training chair, first, the elderly will sit on the seat plate 1 and make their back close to the backrest body, so that their upper body is in an upright state.

[0032] Next, place the upper arm of the patient's arm on the mounting slider 302, then bend the arm and place the lower arm on the training bracket 304, and hold the cylindrical airbag 306 with the hand. Then, the mounting slider 302 will move upward under the action of the electric push rod 303, thereby lifting the elderly's arm to a position flush with the shoulder.

[0033] If the elderly person's arm cannot move autonomously, the training bracket 304 will reciprocate under the action of the micro motor 305, so that the forearm can bend reciprocally, helping the elderly person to complete joint exercise.

[0034] If the elderly's arms can move autonomously, the training bracket 304 will always rotate outward under the action of the micro motor 305. Next, the elderly will use their hands to pull the training bracket 304 back and forth inward, thereby exercising their arm strength while completing joint exercises. Moreover, when the output power of the micro motor 305 increases, the force required for the elderly to pull the training bracket 304 will also increase. Therefore, the training intensity can be freely adjusted.

[0035] Moreover, when the elderly person pulls the training bracket 304 back and forth inward, the columnar airbag 306 is repeatedly squeezed. When the columnar airbag 306 is squeezed, air is discharged through the exhaust hose 307 and the rectangular air nozzle 308. Next, the air is evenly discharged through multiple circular air holes 309, thereby blowing air on the elderly person's back.

[0036] This embodiment, by setting up a limb training mechanism 3 and utilizing the mutual cooperation between the mounting slider 302 and the training bracket 304, can not only help the elderly with limited arm movement to quickly complete arm joint training, but also help the elderly with normal arm movement to perform arm strength training, which can meet the different needs of the elderly and has a wide range of applications; moreover, this embodiment, by setting up a limb training mechanism 3 and utilizing the mutual cooperation between the columnar airbag 306 and the rectangular air nozzle 308, can not only enable the elderly to perform hand grip training while exercising their arm joints, but also use the movement of their hands to blow air to their backs, which can not only ensure the comprehensiveness of the training, but also prevent the back from sweating, thereby improving the comfort of exercise.
