[0002] A wheelchair is an assistive device primarily used for mobility and daily activities by people with limited mobility. A wheelchair typically consists of a seat and a pair of wheels. The wheels in contact with the ground can be manually or electrically operated. Manual wheelchairs are usually pushed by the user themselves, but can also be propelled by someone else to traverse relatively flat or gentle slopes.
[0003] When a wheelchair is needed, the user is moved to the wheelchair seat, and the footrest and armrests are adjusted to give the user a comfortable sitting posture. However, because the headrest height of existing wheelchairs cannot be adjusted, the headrest height cannot be adapted to the user's height and body shape, which may lead to overextension or overcompression of the head and neck, resulting in discomfort or pain. Summary of the Invention

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] Please see Figures 1-4 This invention discloses a smart wheelchair with navigation guidance, comprising a seat 1 for providing rest for the user and a tire 2. The tire 2 is mounted on one side surface of the seat 1. A mounting box 3 is mounted on the top surface of the seat 1. A display 4 is mounted on the inner wall of the mounting box 3. A recording component is mounted on the bottom surface of the display 4. A reinforcing rod 5 is mounted on the top surface of the seat 1. A fixing tube 6 is mounted on one side surface of the reinforcing rod 5. A insertion hole 7 is opened on the inner wall of the fixing tube 6. An adjustment hole 8 is opened on the inner wall of the insertion hole 7. An adjustment component is mounted on the inner wall of the fixing tube 6. A backrest component is mounted on the inner wall of the insertion hole 7.
[0018] The recording components include a GPS module 9, which is installed on the bottom surface of the mounting box 3 and electrically connected to the display 4. A processor 10 is installed on the bottom surface of the mounting box 3 and electrically connected to the display 4. A voice recognition chip 11 is installed on the bottom surface of the mounting box 3 and electrically connected to the processor 10. The voice recognition chip 11 analyzes the voice recorded by the microphone 18 and generates instructions that are transmitted to the processor 10. At this time, the processor 10 will provide the optimal path based on the location of the GPS module 9 and the location of the department, and then display the display 4.
[0019] The adjustment assembly includes a sliding groove 12, an adjustment plate 13 installed on the inner wall of the sliding groove 12, a pull block 14 installed at one end of the adjustment plate 13, a limit post 15 installed at the other end of the adjustment plate 13, and a telescopic spring 16 installed on the outer surface of the limit post 15. The sliding groove 12 is opened on one side surface of the fixed tube 6. When the pull block 14 is pinched and moved, the adjustment plate 13 connected to one side surface of the pull block 14 will move when the pull block 14 moves. At this time, the limit post 15 installed on one side surface of the adjustment plate 13 will move on the inner wall of the fixed tube 6.
[0020] There are two sliding grooves 12, which are equidistantly opened on one side surface of the fixed tube 6. Each sliding groove 12 has an adjusting plate 13 on its inner wall. The outer surface of the adjusting plate 13 is in contact with the inner wall of the sliding groove 12. The limiting post 15 is in contact with the inner wall of the adjusting hole 8. When the limiting post 15 moves, it will squeeze the telescopic spring 16 installed on one side surface. When the limiting post 15 moves, it will retract into the inner wall of the adjusting hole 8, which will hold the bottom surface of the reinforcing plate 17 and pull it upward. When the reinforcing plate 17 is pulled, it will drive the adjusting rod 22 on its bottom surface to move in the inner wall of the insertion hole 7.
[0021] The pillow assembly includes a reinforcing plate 17, a microphone 18 mounted on one side surface of the reinforcing plate 17, a pickup hole 19 mounted on one side surface of the reinforcing plate 17, a speaker 20 mounted on one side surface of the reinforcing plate 17, a headrest 21 mounted on one side surface of the reinforcing plate 17, an adjusting rod 22 mounted on the bottom surface of the reinforcing plate 17, a fixing hole 23 opened on the outer surface of the adjusting rod 22, and the adjusting rod 22 is installed on the inner wall of the insertion hole 7.
[0022] The microphone 18 is electrically connected to the voice recognition chip 11, the speaker 20 is electrically connected to the processor 10, and the pickup holes 19 are two respectively opened on one side surface and the other side surface of the reinforcing plate 17. When the navigation function is needed, the user's head is pressed against the headrest 21 and the user says the department or doctor to be visited. When the user speaks, the microphone 18 installed on one side surface of the reinforcing plate 17 will record the voice used through the pickup holes 19.
[0023] The adjusting rods 22 are installed at two equal intervals on the bottom surface of the reinforcing plate 17. There are ten fixing holes 23, which are arranged in a linear array on the outer surface of the adjusting rods 22. The inner wall of the adjusting hole 8 is in movable contact with the outer surface of the limiting post 15, and the adjusting rod 22 is in movable contact with the inner wall of the insertion hole 7. When the limiting post 15 extends, it will be inserted into the fixing hole 23 opened on the surface of the adjusting rod 22, so that the limiting post 15 and the adjusting hole 8 are fixed to each other, thereby realizing the adjustment of the height of the headrest 21.
[0024] The working principle and usage process of this invention: When using the intelligent medical wheelchair with navigation guidance, the user sits on the top surface of the seat 1. When the navigation function is needed, the user's head is against the headrest 21, and the user speaks the department or doctor they need to go to. When the user speaks, the microphone 18 installed on one side of the reinforcing plate 17 will record the voice through the pickup hole 19. Because the microphone 18 is electrically connected to the voice recognition chip 11, the voice recognition chip 11 will analyze the voice recorded by the microphone 18 and generate instructions that are transmitted to the processor 10. The processor 10 will then provide the optimal route based on the location of the GPS module 9 and the department, and display it on the surface of the display 4. The user can then move according to the display 4 to achieve the navigation guidance function. When turning is required, the processor 10 will control the speaker 20 to emit a voice command to assist the user in adjusting their position.
[0025] When the position of the headrest 21 needs to be adjusted, pinch the pull block 14 and move it. When the pull block 14 moves, it will move the adjusting plate 13 connected to one side of its surface. At this time, the limiting post 15 installed on one side of the adjusting plate 13 will move on the inner wall of the fixing tube 6. When the limiting post 15 moves, it will squeeze the telescopic spring 16 installed on one side of its surface. When the limiting post 15 moves, it will retract into the inner wall of the adjusting hole 8. Then, hold the bottom surface of the reinforcing plate 17 and pull it upward. When the reinforcing plate 17 is pulled, it will move the adjusting plate 13. The adjustment rod 22 on its bottom surface moves within the inner wall of the insertion hole 7. At this time, the height of the headrest 21 is adjusted according to the user's habits. After the adjustment is completed, the pull block 14 is released. When the pull block 14 is released, the compressed telescopic spring 16 will return to its original position. When the telescopic spring 16 returns to its original position, it will push the limiting post 15 to move, and the limiting post 15 will extend out of the adjustment hole 8. When the limiting post 15 extends out, it will insert into the fixing hole 23 opened on the surface of the adjustment rod 22, and the limiting post 15 and the adjustment hole 8 will be fixed to each other, thereby realizing the adjustment of the height of the headrest 21.
