Technical Field

[0001] The present invention relates to the technical field of wheelchairs, and particularly to a road - driving safety intelligent monitoring wheelchair with a ventilator function. Background Art

[0002] With the development of society and the improvement of people's living standards, the number of wheelchair users has gradually increased, including the elderly, the disabled, and those who temporarily need to move with the help of a wheelchair due to injuries or illnesses. For some wheelchair users suffering from respiratory diseases, it is crucial to ensure timely access to stable oxygen supply and real - time monitoring of their breathing conditions during travel. However, traditional wheelchairs only have basic transportation functions and cannot meet the needs of this special group for ventilator functions during road driving.

[0003] At the same time, road safety has always been a key concern for wheelchair users. In the actual road environment, there are various potential dangers, such as obstacles ahead, moving objects suddenly appearing on both sides and behind, etc. Ordinary wheelchairs lack effective road safety monitoring and braking devices. Once an emergency occurs, it is very difficult for wheelchair users to react in time, which easily leads to safety accidents.

[0004] Therefore, it is necessary to develop a wheelchair that can not only provide a ventilator function but also has the ability of road safety intelligent monitoring and braking to ensure the life safety and physical health of wheelchair users during road driving. Summary of the Invention

[0029] Preferably, the rotation speed of the respiratory fan is determined according to the following formula:

[0030] n = (OSmin - OS) ÷ k + n0;

[0042] A power threshold is preset, and the battery pack power is compared with the power threshold. If the battery pack power is lower than the power threshold, give an alarm and prompt the user to charge or replace the battery.

[0043] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0044] The present invention can provide a stable and continuous oxygen supply for users through the oxygen cylinder disposed at the bottom of the frame and the breathing fan connected thereto. Whether traveling on a flat road or a bumpy section, it can ensure the smooth delivery of oxygen, meet the breathing needs of users during travel, and effectively relieve the physical discomfort or health risks that may be caused by hypoxia. The breathing monitoring unit is connected to the oxygen cylinder and can monitor the breathing data of the breathing machine module in real time, such as key indicators like breathing frequency and oxygen concentration. Once an abnormal situation is detected, the control module can timely adjust the working state of the breathing machine module to ensure the breathing safety of users.

[0045] Through the combined application of lidar, camera, and millimeter-wave radar, the present invention realizes the comprehensive monitoring of the road environment in front, on both sides, and behind. The lidar can accurately detect the distance of obstacles on the road ahead, and the camera can identify the types of obstacles, providing more detailed information for judging whether there are potential dangers; the millimeter-wave radar is responsible for monitoring the information of moving objects on the road on both sides or behind, and giving early warnings of possible collision risks. When the road safety monitoring module detects dangerous situations such as the presence of an obstacle ahead and the distance is too close, or moving objects approaching on both sides or behind, the braking unit will quickly respond to lock the wheels and brake to a stop. This automatic braking function greatly shortens the reaction time, effectively reduces the possibility of accidents, and provides reliable safety protection for wheelchair users.

[0046] This intelligent monitoring wheelchair for road travel with a breathing machine function integrates the breathing machine function with road safety monitoring and braking functions, providing a more convenient and safe travel experience for users. Users no longer need to carry complex breathing equipment additionally or worry about road safety issues, greatly improving the autonomy and quality of life.

[0047] The power supply monitoring unit in the battery module can detect the battery pack power in real time and give an early warning according to the power situation. This not only ensures the normal operation of the breathing machine module, road safety monitoring module, and control module, but also reminds users to charge in time to avoid equipment failures or safety hazards caused by insufficient power.

[0056] As Figure 1 - Figure 2 shown, the present invention provides a road driving safety intelligent monitoring wheelchair with a ventilator function, including: a wheelchair module, including a frame 1, wheels 2, a seat 3, and a backrest 4.

[0057] Ventilator module, including an oxygen cylinder 5, a breathing fan 6 and a breathing monitoring unit. The oxygen cylinder 5 is arranged at the bottom of the wheelchair frame 1. The breathing fan 6 is connected to the oxygen cylinder 5. The breathing fan 6 is used to deliver the oxygen in the oxygen cylinder 5 to the user. The breathing monitoring unit is connected to the oxygen cylinder 5 and is used to monitor the breathing data of the ventilator module. The breathing fan is connected to an oxygen mask.

[0058] Road safety monitoring module, including a lidar, a camera, a millimeter-wave radar and a braking unit. The lidar and the camera are arranged at the front end of the wheelchair module. The lidar is used to detect the distance of obstacles on the road ahead. The camera is used to detect the types of obstacles on the road ahead. The millimeter-wave radar is arranged on both sides and at the rear end of the wheelchair module. The millimeter-wave radar is used to detect the information of moving objects on the road on both sides or at the rear. The braking unit is arranged on the wheels 2 and is used to lock the wheels 2 to brake and stop the vehicle.

[0059] Control module, connected to the ventilator module and the road safety monitoring module. The control module is used to receive the breathing data of the ventilator module and the road data detected by the road safety monitoring module, and control the ventilator module and the braking unit according to the breathing data and the road data.

[0060] Battery module, including a battery pack and a power supply monitoring unit. The battery pack is connected to the ventilator module, the road safety monitoring module and the control module. The battery pack is used to provide electrical energy for the ventilator module, the road safety monitoring module and the control module. The power supply monitoring module is connected to the battery pack and is used to detect the battery pack power and give an alarm according to the battery pack power. The battery module can be installed at the bottom or the back of the wheelchair module frame.

[0061] The present invention can provide users with comprehensive breathing support and road safety monitoring, ensuring the safety and comfort of users during road driving. First, the design of the ventilator module enables users to obtain sufficient oxygen supply when needed, and at the same time, the breathing monitoring unit can monitor the user's breathing status in real time to ensure the effective operation of the ventilator. Second, through the coordinated action of the lidar, camera and millimeter-wave radar, the road safety monitoring module can comprehensively sense the surrounding environment, timely detect obstacle and moving object information, and provide safety guarantee for the user's driving. The setting of the braking unit can quickly brake and stop the vehicle in case of emergency to avoid potential dangers. In addition, as the core of the entire system, the control module can receive and process data from each module to achieve intelligent control and adjustment. Finally, the design of the battery module ensures the continuous operation of the system, and the addition of the power supply monitoring unit further improves the reliability and safety of the system.

[0062] In some embodiments of the present application, the wheelchair module further includes armrests 7 and footrests 8. The armrests 7 are rotatably arranged on both sides of the frame 1, and the footrests 8 are arranged at the bottom of the frame 1.

[0063] It is understandable that the rotatable design of the armrest 7 enables the user to adjust the position of the armrest 7 according to their own needs, facilitating the user's access to and from the wheelchair. The setting of the footrest 8 provides stable foot support for the user, especially during driving, which helps to maintain the user's body balance. This improvement not only enhances the practicality and user experience of the wheelchair, but also further enhances the safety of the wheelchair during road driving.

[0064] In some embodiments of the present application, the respiration monitoring unit includes: a first pressure sensor disposed inside the oxygen cylinder, the first pressure sensor being configured to detect the oxygen pressure inside the oxygen cylinder; a flow sensor disposed on the gas delivery conduit of the oxygen cylinder, the flow sensor being configured to detect the user's respiration flow rate; a second pressure sensor disposed on the gas delivery conduit of the oxygen cylinder, the second pressure sensor being configured to detect the user's respiration pressure; and a blood oxygen saturation sensor disposed on the wheelchair module, the blood oxygen saturation sensor being configured to detect the user's blood oxygen saturation.

[0065] It is understandable that by integrating the first pressure sensor, the flow sensor, the second pressure sensor, and the blood oxygen saturation sensor, the respiration monitoring unit can monitor the user's oxygen usage, respiration flow rate, respiration pressure, and blood oxygen saturation in real time, thereby providing accurate respiration health monitoring for the user. This design not only helps to promptly detect the user's respiration abnormalities, but also can intelligently adjust the oxygen supply according to the user's actual respiration condition to ensure the user's respiration safety during driving.

[0066] In some embodiments of the present application, the control module includes: a receiving unit configured to receive the respiration data of the ventilator module and the road data detected by the road safety monitoring module; a processing unit configured to set the operating parameters of the ventilator module according to the respiration data and set the control instructions for the braking unit according to the road data; and a control unit configured to control the ventilator module according to the operating parameters and control the braking unit according to the control instructions. The control module is disposed at the armrest of the wheelchair module or other positions convenient for the user to use.

[0067] It can be understood that by integrating the receiving unit, the processing unit, and the control unit, the control module realizes the dual intelligent control of the ventilator module and the braking unit. The receiving unit can obtain the breathing data of the ventilator module and the road data of the road safety monitoring module in real time, ensuring the accuracy and timeliness of the data. The processing unit then intelligently sets the operating parameters of the ventilator module and the control instructions of the braking unit according to these data, realizing the precise response to the user's breathing needs and the real-time monitoring of road safety. The control unit then accurately controls the working states of the ventilator module and the braking unit according to the instructions of the processing unit, ensuring the breathing safety and road driving safety of the user during driving.

[0068] In some embodiments of the present application, the processing unit is configured to set the operating parameters of the ventilator module according to the breathing data, including: the breathing data includes oxygen pressure, breathing flow rate, breathing pressure, and blood oxygen saturation; an oxygen pressure threshold is set, the oxygen pressure is compared with the oxygen pressure threshold, and whether to replace the oxygen cylinder is determined according to the determination result; if the oxygen pressure is greater than the oxygen pressure threshold, the use state of the oxygen cylinder is maintained; if the oxygen pressure is less than or equal to the oxygen pressure threshold, a prompt to replace the oxygen cylinder is given.

[0069] It can be understood that by carefully analyzing the oxygen pressure in the breathing data and comparing it with the preset oxygen pressure threshold, the processing unit can intelligently judge the remaining capacity of the oxygen cylinder, thereby timely reminding the user to replace the oxygen cylinder. This function effectively avoids breathing interruption caused by insufficient oxygen supply, ensuring continuous oxygen supply for the user during driving. At the same time, this design also reduces the operation burden of the user through an automated judgment process, improving the convenience and safety of use.

[0070] In some embodiments of the present application, the processing unit is configured to set the operating parameters of the ventilator module according to the breathing data, and further includes: a blood oxygen saturation threshold is set, the blood oxygen saturation is compared with the blood oxygen saturation threshold, and whether to adjust the operating state of the breathing fan is determined according to the comparison result; if the blood oxygen saturation is greater than or equal to the blood oxygen saturation threshold, the operating state of the breathing fan is not adjusted; if the blood oxygen saturation is less than the blood oxygen saturation threshold, the blood oxygen saturation difference between the blood oxygen saturation and the blood oxygen saturation threshold is determined, and the rotation speed of the breathing fan is determined according to the blood oxygen saturation difference, breathing flow rate, and breathing pressure.

[0071] It can be understood that by real-time monitoring the blood oxygen saturation and comparing it with a preset blood oxygen saturation threshold, the processing unit can intelligently determine whether the user's blood oxygen level is within a safe range. When the blood oxygen saturation is lower than the threshold, the processing unit will not only precisely adjust the rotation speed of the breathing fan according to the degree of decrease in blood oxygen saturation, but also comprehensively consider the changes in breathing flow and breathing pressure. This comprehensive regulation strategy ensures that the ventilator module can provide appropriate assistance according to the actual breathing needs of the user, effectively improving the oxygen therapy effect.

[0072] In some embodiments of the present application, the rotation speed of the breathing fan is determined according to the following formula:

[0073] n = (OSmin - OS) ÷ k + n0;

[0074] k = f(Q, P) ÷ n0;

[0075] Wherein, n represents the rotation speed of the breathing fan, OSmin represents the blood oxygen saturation threshold, OS represents the blood oxygen saturation, k is the comprehensive influence coefficient, n0 represents the initial rotation speed of the breathing fan, and f(Q, P) represents the functional relationship between the blood oxygen saturation and the breathing flow and breathing pressure.

[0076] It can be understood that by introducing a specific mathematical formula to determine the rotation speed of the breathing fan, the adjustment process becomes more precise and controllable. This quantitative regulation method not only improves the response speed and accuracy of the ventilator module, but also makes the entire system more stable and reliable. In addition, this technical solution also provides personalized breathing assistance treatment for users, intelligently adjusting the rotation speed of the breathing fan according to physiological parameters such as the blood oxygen saturation, breathing flow, and breathing pressure of different users, to achieve personalized oxygen therapy effects.

[0077] In some embodiments of the present application, the processing unit sets the control instruction of the braking unit according to the road data, including: the road data includes the obstacle distance, obstacle type, and moving body information; setting the driving speed of the wheelchair and the control instruction of the braking unit according to the obstacle distance and obstacle type; setting the driving direction of the wheelchair according to the moving body information. If the moving body information is that the moving body is moving behind, then set the wheelchair to change lanes; if the moving body information is that the moving body is moving on both sides, then set the wheelchair to maintain the original lane.

[0078] It can be understood that by integrating the obstacle distance, obstacle type, and moving object information in the road data, the processing unit can intelligently set the driving speed of the wheelchair and the control command of the braking unit. This design enables the wheelchair to automatically adjust its driving strategy when facing different road environments, ensuring driving safety. In particular, when a moving object is detected approaching from behind, the wheelchair can actively change lanes to avoid potential collision risks. When moving objects are detected on both sides, the wheelchair maintains its original lane, ensuring both driving efficiency and avoiding potential safety hazards caused by unnecessary lane changes.

[0079] In some embodiments of the present application, the processing unit sets the driving speed of the wheelchair and the control command of the braking unit according to the obstacle distance and obstacle type, including: setting a safety distance, comparing the obstacle distance with the safety distance, if the obstacle distance is less than or equal to the safety distance, setting the braking unit to start a braking command and setting the wheelchair to change lanes; if the obstacle distance is greater than the safety distance, not starting the braking command and determining whether the obstacle type is an immovable obstacle; if the obstacle type is an immovable obstacle, adjusting the driving speed to 25% of the original driving speed; if the obstacle type is a movable obstacle, adjusting the driving speed to 50% of the original driving speed.

[0080] It can be understood that by further refining the setting conditions of the braking command, the processing unit can more precisely control the driving speed and braking behavior of the wheelchair according to different obstacle distances and obstacle types. When the obstacle distance is less than or equal to the preset safety distance, the timely activation of the braking unit can effectively avoid collisions, and the design of the wheelchair changing lanes further enhances the obstacle avoidance ability. In the case where the obstacle distance is greater than the safety distance, the processing unit can intelligently adjust the driving speed according to the obstacle type, ensuring both the driving efficiency of the wheelchair and the safety during driving. In particular, for immovable obstacles, the significant reduction in driving speed helps the wheelchair pass smoothly, while for movable obstacles, a moderate speed adjustment can maintain the driving coherence of the wheelchair as much as possible while ensuring safety.

[0081] In some embodiments of the present application, the power supply monitoring module is used to detect the battery pack power and give an early warning according to the battery pack power, including: presetting a power threshold, comparing the battery pack power with the power threshold, if the battery pack power is lower than the power threshold, giving an early warning and prompting the user to charge or replace the battery.

[0082] It is understandable that through the real-time monitoring and early warning functions of the power supply monitoring module, users can timely understand the power status of the battery pack and avoid sudden shutdowns caused by insufficient power. When the power of the battery pack is lower than the preset power threshold, the timely triggering of the early warning system not only reminds users to charge or replace the battery in a timely manner, but also effectively prevents potential safety hazards that may be caused by power exhaustion.

[0083] Those skilled in the art should understand that the embodiments of the present application can be provided as methods, systems, or computer program products. Therefore, the present application can take the form of a completely hardware embodiment, a completely software embodiment, or an embodiment combining software and hardware aspects. Moreover, the present application can take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) that contain computer-usable program code.

[0084] The present application is described with reference to the flowcharts and / or block diagrams of methods, apparatuses (systems), and computer program products according to the embodiments of the present application. It should be understood that each process and / or block in the flowchart and / or block diagram can be implemented by computer program instructions, and the combination of processes and / or blocks in the flowchart and / or block diagram can also be implemented. These computer program instructions can be provided to the processor of a general-purpose computer, a special-purpose computer, an embedded processor, or other programmable data processing devices to generate a machine, so that the instructions executed by the processor of the computer or other programmable data processing devices generate means for implementing the specified functions in Figure 1 one process or multiple processes and / or blocks Figure 1 one block or multiple blocks.

[0085] These computer program instructions can also be stored in a computer-readable memory that can direct a computer or other programmable data processing device to work in a specific manner, so that the instructions stored in the computer-readable memory generate a manufactured article including instruction means, and the instruction means implement the specified functions in Figure 1 one process or multiple processes and / or blocks Figure 1 one block or multiple blocks.

[0086] These computer program instructions can also be loaded onto a computer or other programmable data processing device, so that a series of operation steps are executed on the computer or other programmable device to generate a computer-implemented process, and thus the instructions executed on the computer or other programmable device provide steps for implementing the specified functions in Figure 1 one process or multiple processes and / or blocks Figure 1 one block or multiple blocks.
