Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0021] Please refer to Figure 1-5 , the present invention provides a technical solution: an air cushion wheelchair with adjustable sitting posture, including a wheelchair frame 1, an armrest 3, a support rod 5, a front support leg 6 and a rear support leg 8. The lower surface of the wheelchair frame 1 is fixedly connected to the upper end of the rear support leg 8, and the front side surface of the wheelchair frame 1 is fixedly connected to the upper end of the front support leg 6. A support rod 5 is fixedly connected to the front end of the wheelchair frame 1, and the upper surface of the wheelchair frame 1 is fixedly connected to the lower end of the armrest 3. A slide rail 4 is provided inside the armrest 3, and a skateboard 401 is slidably connected inside the slide rail 4. One end of the skateboard 401 is fixedly connected to a push rod 402, and one end of the push rod 402 is fixedly connected to a bottom plate 7. The bottom plate 7 is located on the upper surface of the wheelchair frame 1. A plurality of airbags 2 are installed on the upper surface of the bottom plate 7, and a number of pressure sensors 203 are installed inside the plurality of airbags 2. The bottom of the plurality of airbags 2 is fixedly installed with a controller 201, and one side surface of the controller 201 is connected to a micro air pump 202 through a wire. The micro air pump 202 is installed on the side surface of the airbag 2.

[0022] As a technical optimization scheme of the present invention, a through hole 403 is opened inside one end of the slide rail 4, and a clamping block 4011 is provided inside the through hole 403. The inner side surface of the clamping block 4011 is fixedly connected to an elastic sheet 4012, and one end of the elastic sheet 4012 is fixedly connected to one end of the skateboard 401. By the cooperation of the clamping block 4011 and the elastic sheet 4012 at one end of the skateboard 401 with the through hole 403, the installation and disassembly of the skateboard 401 and the bottom plate 7 are facilitated. Therefore, the disassembly of the airbag 2 on the upper surface of the bottom plate 7 is facilitated, and thus the maintenance and repair of the airbag 2 are facilitated.

[0023] As a technical optimization solution of the present utility model, an L-shaped rod 701 is fixedly connected to the upper surface of the bottom plate 7, and a cloth sleeve 703 is sleeved on the side surface of the L-shaped rod 701. The upper end of the cloth sleeve 703 is fixedly connected to the lower surface of multiple air bags 2. A nut 702 is threadedly connected to the side surface of one end of the L-shaped rod 701, which facilitates the removal of the multiple air bags 2 from the bottom plate 7, so as to clean the air bags 2 after long-term use, ensuring the cleanliness of the air bags 2 and further improving the comfort of the patient during use.

[0024] As a technical optimization solution of the present utility model, the length of a single air bag 2 is 15 cm, and the width of the air bag 2 is 10 cm. The thickness of the air bag 2 can be adjusted between 5 and 10 cm through a pressure sensor 203, a micro air pump 202 and a controller 201, so it can be applied to different requirements and scenarios.

[0025] As a technical optimization solution of the present utility model, the air bag 2 is composed of a protective and sealing layer. The protective layer is made of breathable, waterproof and anti-slip canvas fabric, while the sealing layer is made of rubber material, thus ensuring that the user remains dry and comfortable during use.

[0026] As a technical optimization solution of the present utility model, a pedal 501 is fixedly connected to the lower end of the support rod 5, and a single air bag 2 is installed on the upper surface of the pedal 501. The single air bag 2 installed on the upper surface of the pedal 501 can improve the comfort of the patient's legs and promote blood circulation in the patient's legs at the same time.

[0027] When the present utility model is in use, the patient sits on the upper surface of the air bag 2. Then, through the pressure sensor 203 inside the multiple air bags 2, the pressure of the patient sitting on the wheelchair will be transmitted to the controller 201. At this time, the controller 201 will inflate the air bag 2 through the micro air pump 202 according to the pressure value transmitted by the pressure sensor 203, so that the air bag 2 can better fit the patient's body. When the patient stays in a certain posture for a long time, at this time, the pressure sensor 203 will detect that the pressure at some positions of the patient is relatively large, so it will start the corresponding micro air pump 202 through the controller 201 to adjust a certain posture for the patient. At this time, the local pressure of the patient can be reduced and the comfort of the patient can be improved. After using for a period of time, the patient's family member can remove the slide plate 401 from the inside of the slide rail 4 by pressing the slide plate 401 inside the through hole 403. At this time, the push rod 402 pushes the bottom plate 7 and the air bag 2 to separate from the wheelchair frame 1. Then, the patient's family member can inspect or repair the air bag 2. After that, the family member can remove the nut 702 from the side surface of the L-shaped rod 701, and then further remove the air bag 2 from the bottom plate 7. Then, the air bag 2 can be thoroughly cleaned to maintain the cleanliness of the air bag 2 during use, and at the same time, the cleaning difficulty of the patient's family member is reduced and the cleaning efficiency of the air bag 2 is improved.
