In addition, the wheelchair is equipped with an anti-tipping sensor at the bottom that automatically locks the wheels when a risk of tipping is detected to prevent accidents.

[0031] Information interaction module: The tablet computer 3 provided on the armrest 4 is used as an information interaction medium. When not in use, it can be hidden beside the armrest 4 without taking up additional space. When in use, it is pulled out and placed horizontally above the knees of the wheelchair seat. The tablet computer 3 on the front can be used by the user to operate, such as customizing various functions through the APP. The desktop on the back can be used to place sundries, tableware, etc. It is highly practical. Through the key input device provided on the other armrest 4 and the real-time response of the intelligent voice assistant, it can provide users with weather, news and other information.

[0032] Monitoring Module: The hardware monitoring unit, consisting of a wristband and camera attached to the wheelchair, works in conjunction with the software monitoring unit to comprehensively ensure user safety. The software monitoring unit automatically detects obstacles and avoids collisions. The health monitoring unit monitors vital signs such as heart rate and blood pressure in real time and synchronizes this data to the cloud, facilitating remote monitoring by family members and medical staff. The GPS positioning system allows family members to track the user's location in real time to ensure their safety.

[0033] Input module: supports multiple input methods such as key input, voice input, ARVR input, brain-computer input, etc. Different input methods can adapt to the needs of different users, especially brain-computer interface technology, which realizes mind control and greatly provides convenience for people with disabilities.

[0034] Seat Module: The seat cushion is made of pure natural latex, which is highly breathable and has a massage function, relieving fatigue from prolonged sitting. The backrest angle can be adjusted from 0 to 90 degrees to meet the user's different needs, such as sitting or lying down. The support angle can be intelligently adjusted to prevent side slippage and enhance comfort. The armrests are height-adjustable. The built-in temperature sensor is electrically connected to the temperature control module to automatically adjust the temperature for enhanced user comfort. The roller curtain at the front footrest rises to the front waist level after the user is seated, providing windproof and heat insulation. The temperature control system also automatically adjusts the temperature inside the roller curtain according to the temperature, ensuring user comfort in all seasons.

[0035] The toilet opening is made of silicone and has a narrow oval shape. The honeycomb at the front of the toilet seat features a hollowed-out structure to prevent urine from splashing. The waste collection box 7 underneath is replaceable and easy to clean. The sensor inside the smart toilet 6 automatically detects the need for urination and defecation, and the cleaning and drying mechanism automatically activates after use to ensure hygiene. The smart toilet 6 also features odor absorption and fragrance functions to keep the environment fresh, and its detachable design facilitates cleaning and maintenance.

[0036] The wheelchair also includes a constant temperature module and a lighting and sound module. The constant temperature module uses built-in sensors to monitor the internal temperature in real time, controlling the temperature control module to automatically adjust the seat and back heating or cooling to ensure the user is always comfortable. The lighting and sound module's intelligent sensor light automatically illuminates at night, providing soft lighting; the adaptive safety lighting system improves travel safety when out and about at night; and the built-in miniature speaker located in the rear armrest automatically adjusts the volume according to the ambient noise to ensure clear listening.

[0037] In addition, the wheelchair shown in this application can also interact with the supporting community-wide smart devices, which is explained below through the examples. Example 1

[0038] Scene: Elderly people returning home from the community garden Automatic connection to smart door locks: When a senior uses a voice command to "navigate home," the smart wheelchair's integrated system automatically activates community-wide smart device interaction. When the wheelchair arrives within three meters of the residential unit's entrance, the wheelchair's built-in sensors establish a wireless connection with the smart door lock, automatically verifying the user's identity (via a pre-set wheelchair ID and door lock binding). The door lock automatically unlocks and emits a "door opened" notification, eliminating the need for the senior to manually retrieve a key or enter a password.

[0039] Smart Home Integration: Upon entering the house, the wheelchair automatically connects to the living room's smart home system and, based on pre-set habits (e.g., returning home in the evening), automatically turns on the main living room light (adjusted to 70% brightness to avoid glare), adjusts the air conditioning temperature to 26°C (summer) or 22°C (winter), and switches the TV to a news channel (based on the elderly's daily preferences). This entire process requires no manual intervention, achieving a seamless transition from entry to comfortable seating.

[0040] Smart elevator call: If an elderly person lives on the 5th floor and arrives at the elevator lobby on their way back, the wheelchair sends a command to the smart elevator via IoT technology, notifying them of their destination floor (the 5th). The elevator automatically moves from the current floor to the 1st floor, opens the car door, and announces, "The elevator has arrived at the 1st floor, please enter." Once inside, the wheelchair automatically parks inside the car (avoiding the doorway) and announces, "We have arrived at the 5th floor, please exit safely."

[0041] Automatic meal ordering at the community canteen: At lunchtime, a senior citizen can request "Go to the community canteen." The wheelchair navigates to the canteen and automatically connects to the canteen's smart ordering system. A camera identifies available seats (preferably window seats with ample space), drives to the desired seat, and announces "Arrived at table." Simultaneously, a tablet automatically displays the day's menu. The senior citizen can then say, "One steamed fish, one bowl of millet porridge." The system automatically places the order and synchronizes it with the canteen kitchen. After the meal, the wheelchair completes the payment using a linked payment account, eliminating the need to queue or pay manually. Example 2

[0042] Scenario: Elderly people moving around independently in designated areas of the community Autonomous driving within designated areas: The community designates safe activity areas for wheelchairs (such as central gardens, fitness areas, and corridors). Elderly people input "go to the fitness area" through voice, and the intelligent driving function is activated: the intelligent navigation system plans the shortest path based on the real-time map (avoiding fitness equipment areas and pedestrian gathering points). During driving, the system detects obstacles (such as children who suddenly run by or parked strollers) through the front camera and side sensors, slows down 1.5 meters in advance, and slightly adjusts the direction to avoid them. Upon arrival, the system automatically stops next to the rest chairs in the fitness area.

[0043] Emergency response: If an elderly person suddenly becomes dizzy in the fitness area, the health monitoring module detects that the heart rate suddenly rises to 130 beats / minute (far exceeding the normal range) and the blood pressure rises to 160 / 100 mmHg, and the emergency execution function is immediately triggered: The intelligent integrated system automatically sends an emergency signal to the community medical station, including real-time location (rest chair on the northeast side of the fitness area), heart rate and blood pressure data, and a preliminary diagnosis of "suspected sudden hypertension"; The wheelchair will announce "physical abnormality detected, medical staff have been contacted, and you will be taken to the community medical station" and then automatically activate the intelligent driving function and drive at a low speed (0.8 m / s) to the community medical station (the preset designated medical area). Vital sign data is continuously monitored during driving, updated every 30 seconds and sent to the medical station. At the same time, a warning light is turned on in front of the wheelchair to remind pedestrians around that "emergency transfer is being carried out, please give way."

[0044] Manual mode backup: If the elderly want to manually control the wheelchair to slowly tour the garden, they can switch to "manual pushing mode" through the control panel. The motor assistance force will be weakened, making it easier for the elderly to adjust the direction independently, taking into account both autonomy and safety. Example 3

[0045] Scenario: Daily home life and health management for the elderly Real-time vital sign monitoring and early warning: Every morning, when an elderly person sits in their wheelchair, the health monitoring module on the seat cushion and backrest automatically activates. Contact sensors monitor heart rate (e.g., 72 beats / minute) and blood pressure (e.g., 135 / 85 mmHg). The data is displayed in real time on a tablet and simultaneously uploaded to family members and the community health management platform. If the blood pressure rises to 150 / 95 mmHg (outside the preset normal range) on a given day, the system will immediately issue a voice prompt, "Blood pressure is high. Rest and blood sugar measurement are recommended." A reminder message, "The elderly person's blood pressure is currently abnormal. Please pay attention," is also pushed to the family member's mobile app.

[0046] Behavioral reminders for medical and nursing plans: Based on the health and nursing plan formulated by the community doctor (such as "15-minute leg massage at 10 am every day" and "Low-salt diet for dinner"), the voice assistant will automatically remind you at the appointed time: "It is 10 o'clock now, time for leg massage, and the leg guard massage function has been activated for you" (the vibration massage mode of the leg guard structure is activated simultaneously); 30 minutes before dinner, a reminder will be given: "Please avoid high-salt foods for dinner, and it is recommended to eat vegetables and whole grains."

[0047] Schedule and timed reminders: The physical examination is preset at 9:00 am every Wednesday. At 8:00 am on the same day, the wheelchair will give a voice prompt, "There is a physical examination at 9:00 am today. The route to the community physical examination center has been planned for you. Please bring your ID card or medical insurance card." If the elderly have the habit of taking a nap, set 13:00-14:30 as the nap time. At 13:00, it will prompt "You are ready for a nap. Do you want to adjust the backrest to lying mode?". At 14:30, it will gently remind you, "Nap time is over. It is recommended to sit up slowly and move around." Example 4

[0048] Scenario: Elderly people going out at night and special needs management Whole body constant temperature and lighting protection: In winter nights, when the elderly need to go out to take out the trash, the wheelchair's constant temperature system detects the ambient temperature of 5°C and automatically starts heating the seat, backrest and armrests (maintaining 28°C). The roller shutter of the leg guard structure automatically rises and heats to 25°C at the same time to prevent cold. When driving, the luminous warning strip on the edge of the wheelchair lights up (soft yellow light), and the smart sensor lights on both sides automatically turn on (illuminating the 2-meter range in front). When encountering other pedestrians, the adaptive safety lighting system dims the brightness (to avoid glare) to ensure visibility without disturbing others.

[0049] Smart Toilet and Battery Life Support: When a senior needs to use the toilet while strolling in the community, they can voice-command "Open Toilet." A silicone opening at the rear of the chair automatically deploys, and a honeycomb structure within the urination area prevents urine from splashing. After use, a sensor triggers a cleaning cycle (rinse with fresh water and dry with warm air at 50°C), activating the odor absorption module (releasing a light lemon fragrance). If the tablet displays "Battery Remaining 20%," the senior can command "Navigate to Nearest Charging Point." The wheelchair will be directed to a community charging station, where it will quickly charge for 30 minutes, restoring the battery to 80%, sufficient for the return trip.

[0050] Flexible switching of input methods: If the elderly have difficulty moving their fingers, they can use voice input to "turn on the music"; if the environment is noisy (such as a community event site) and voice recognition is disturbed, they can switch to touch operation (click the "Music" icon on the armrest panel); for users with upper limb disability, brain-computer input can be enabled (through the preset brain wave command "Play news") to achieve contactless operation.

[0051] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
