Description

Technical Field

[0001] The present invention relates to the technical field of wheelchairs, and in particular to an AI interactive wheelchair. Background Art

[0002] A wheelchair is a chair with wheels that can help replace walking. It is an important means of transportation for the injured, sick, and disabled for home rehabilitation, transportation, medical treatment, and outdoor activities. A wheelchair not only meets the transportation needs of the physically disabled and those with limited mobility, but more importantly, it makes it easier for family members to move and care for the patients, allowing the patients to exercise and participate in social activities with the help of a wheelchair.

[0003] In medical work, most people with leg disabilities who need rehabilitation training and the elderly with limited leg strength need to use wheelchairs for transportation. Most of these people have insufficient leg strength but have not completely lost the ability to walk, so they need to stand or walk regularly. The existing wheelchair structure is relatively traditional and its intelligence level is not high. Moreover, when the above-mentioned people need to stand, they have to rely on the support of other people or the support of objects such as bed edges and railings to stand stably. If they stand directly, due to insufficient leg strength, the pressure is concentrated on the hands, and the armrests of the wheelchair are in an overall backward position. It is easy for the wheelchair to slide to the side away from the user due to the deviation of the force direction, and there is a risk of falling. In this regard, the present invention provides an AI interactive wheelchair to solve the above problems. Summary of the Invention

Through the sunshade component, ultraviolet rays can be sensed when the user moves outdoors, so as to remind the user whether it needs to be blocked, thereby improving the comfort when used outdoors.

[0034] It should be noted that the front moving part includes a front fixed rod 203 fixed to the bottom of the leg rack 201, a front connecting plate 204 fixed between the outer side of the front fixed rod 203 and the left side of the corresponding leg rack 201, and a front wheel 205 fixedly installed at the bottom of the front connecting plate 204; the rear moving part includes two rear fixed plates 206 fixedly installed at the bottom of the main seat plate 1, a rear fixed rod 207 fixedly installed at the left side of the bottom of the rear fixed plate 206, a rear connecting plate 208 fixed at the bottom end of the rear fixed rod 207, and a universal wheel 209 fixedly installed at the bottom of the rear connecting plate 208, so that the main seat plate 1 can move normally and stably. The standing component is located between the armrest frame 212 on the same side and the opposite side of the walking wheel 211, and will not hinder the operation of the walking wheel 211, wherein the two walking wheels 211 are driven by two transmission motors respectively, so as to control the operation and speed of the transmission motor, thereby achieving the steering effect.

[0035] In this embodiment, the AI interaction component is a structure used to improve the intelligence level of the wheelchair so that the user experience can be greatly improved.

[0036] like Figure 1 and Figure 2 As shown, the AI interaction components include a number of human infrared sensors 301 fixedly installed between the main seat plate 1 and the outer side of the rear movable part, an ultrasonic ranging sensor 302 fixedly installed at the bottom of the foot pedal 202, a visual control screen 303 rotatably installed on the top of the front armrest panel 213 through a damping shaft and connected to the Wenxin Yiyan intelligent model, a face recognition camera 304 integrated on the top of the visual control screen 303, a monitoring bracelet 305 connected to the visual control screen 303 through a detachable wire, a headrest 306 fixedly installed on the right side of the push handle 216, and two voice receiving and releasing modules 307 fixedly installed on the front and back of the headrest 306 respectively.

[0037] It should be noted that several human infrared sensors 301 are respectively fixedly installed on the front and back of the main seat plate 1 and the left side of the rear fixed rod 207, so that the human infrared sensor 301 can sense approaching hot people, so as to facilitate the wheelchair user to make judgments. The monitoring bracelet 305 has a built-in heart rate monitoring module and a temperature and humidity monitoring module, which can monitor the ambient temperature and humidity around the user, and can also monitor the user's heart rate to improve the professionalism of use. At the same time, the detachable wire is a magnetic data cable and has a charging function, so that the monitoring bracelet 305 can be connected to the visual control screen 303 for use, and can also be used separately.

[0038] In addition, the human infrared sensor 301, the ultrasonic ranging sensor 302, the face recognition camera 304, the monitoring bracelet 305, and the voice receiving and releasing module 307 are all signal-connected to the visual control screen 303. The voice receiving and releasing module 307 includes a voice receiving module and a microphone module. The visual control screen 303 is internally integrated with a control chip and a microcontroller to play the role of overall control. At the same time, under the action of the voice receiving module, the user can also set the control program through voice to facilitate interaction using voice. At the same time, the visual control screen 303 is connected to the cloud and the Baidu Wenxin Yiyan artificial intelligence model, and has the functions of wireless Internet access and AI interaction. It can then access the network and input corresponding information to provide entertainment for the user. At the same time, it also has the ability of AI dialogue, which effectively improves the overall entertainment. Moreover, the face recognition camera 304 can recognize the user's face and can store a variety of different facial information, so that the input instructions and AI interactive dialogue functions for different faces are different, thereby improving the user's privacy.

[0039] In this embodiment, the standing assembly is a structure for facilitating the user to stand directly using the wheelchair and for facilitating the user to stand with support.

[0040] like Figure 3 、 Figure 5 and Figure 6 As shown, the standing assembly includes an electric push rod 401 fixedly mounted on the bottom of the armrest board 213, a support plate 402 fixedly mounted on the bottom of the armrest board 213, a standing board 403 placed on the top of the support plate 402, an anti-slip pad 404 bonded to the top of the standing board 403, a U-shaped block 405 fixed to the bottom of the standing board 403, a movable hole 406 opened on the left side of the U-shaped block 405, two guide rods 407 fixed between the top wall and the bottom wall of the movable hole 406, and a sliding connection between the two guide rods. A push block 408 is fixedly connected to the output shaft of the corresponding electric push rod 401 between the outer sides of 407; a telescopic spring 409 is fixed between the top of the push block 408 and the inner top wall of the corresponding movable hole 406; two first driving mechanisms 410 are fixedly installed on the opposite sides of the two U-shaped blocks 405; an active rod 411 is rotatably connected to the inner side of the bottom of the U-shaped block 405 through a bearing; an active housing 412 is fixed to the outer side of the active rod 411; and a driven rod 413 is rotatably connected to the inner bottom of the active housing 412 through a bearing. , four synchronous wheels 414 respectively fixedly mounted on the outside of the two active rods 411 and the two driven rods 413, a synchronous belt 415 meshingly connected to the outside of the two corresponding synchronous wheels 414, two equipment boxes 416 respectively fixed to the opposite sides of the two active shells 412, two linkage rods 417 respectively fixed to the opposite sides of the two driven rods 413, a transmission rod 418 rotatably connected to the inside of the equipment box 416 through a bearing, and respectively sleeved on the outside of the two linkage rods 417 and the two transmission rods 418 Four gears 419, a swing block 420 fixed to the outside of the transmission rod 418, a driven housing 421 fixed to the left side of the swing block 420, a contact block 422 fixed to the top of the driven housing 421, two support blocks 423 fixed to the bottom of the driven housing 421, a telescopic rod 424 fixedly installed at the bottom of the driven housing 421, a squeezing spring 425 fixedly installed at the bottom of the driven housing 421, a squeezing plate 426 fixed to the bottom of the squeezing spring 425, and an adjusting wheel 427 fixedly installed at the bottom of the squeezing plate 426.

[0041] It should be noted that if Figure 4As shown, the output shaft of the first driving mechanism 410 passes through the outer side of the corresponding U-shaped block 405 and is fixedly connected to the end of the corresponding active rod 411, so that the first driving mechanism 410 can drive the active rod 411 to rotate, and the opposite ends of the two linkage rods 417 pass through the active shell 412 and the equipment box 416 in turn, so that the gear 419 can perform transmission work on the inner side of the corresponding equipment box 416, and the two gears 419 inside the same equipment box 416 are engaged with each other, and the opposite ends of the two transmission rods 418 respectively pass through the opposite sides of the two equipment boxes 416, so that the gear 419 driven by the linkage rod 417 can drive the other gear 419 to rotate, thereby allowing the transmission rod 418 to rotate.

[0042] In addition, the swing block 420 is located between the opposite sides of the two equipment boxes 416, and a rubber pad is bonded to the top of the abutment block 422, and the top of the rubber pad abuts against the bottom of the corresponding active shell 412, so that the swing block 420 can normally drive the driven shell 421 to rotate, and can allow the abutment block 422 to move to the bottom of the corresponding active shell 412 for abutment support, thereby allowing the entire standing assembly for the user to support standing to form a straight line perpendicular to the ground, thereby improving the stability of the support.

[0043] At the same time, a non-slip and wear-resistant block is bonded to the bottom of the support block 423, and the bottom of the non-slip and wear-resistant block can abut against the ground, so that the support block 423 can play a stable supporting role through the non-slip and wear-resistant block. In the natural state, the anti-slip and wear-resistant block is located above the bottom of the adjusting wheel 427. After pressure is applied, the anti-slip and wear-resistant block can abut against the ground, thereby replacing the adjusting wheel 427 to play a supporting role.

[0044] In addition, the telescopic rod 424 is located on the inner side of the corresponding extrusion spring 425, and the top of the extrusion plate 426 is fixedly connected to the bottom end of the corresponding telescopic rod 424. The telescopic rod 424 consists of a sleeve and a square rod slidably connected to the inner side of the sleeve, so that the square rod can play a role in rotation limiting, so that the telescopic rod 424 can only move up and down. Among them, the top of the square rod passes through the top of the corresponding sleeve, and the bottom end of the square rod is fixed with a limiting plate slidably connected to the inner side of the sleeve. The diameter of the limiting plate is larger than the diameter of the square rod, so that the limiting plate can limit the square rod and prevent it from detaching, thereby allowing the adjusting wheel 427 to achieve the effect of moving up and down under the cooperation between the telescopic rod 424 and the extrusion spring 425. The position of the driven housing 421 can be conveniently slidably adjusted through the adjusting wheel 427. When stable support is required, the support block 423 is used to provide support.

[0045] In this embodiment, the sunshade assembly is a structure used to block sunlight to a certain extent outdoors so as to effectively improve the overall comfort.

[0046] like Figure 1 、 Figure 2 and Figure 7 As shown, the sunshade assembly includes a mounting frame 501 fixed between the tops of the two rear fixed plates 206, two symmetrical plates 502 fixed to the right side of the mounting frame 501, a second driving mechanism 503 fixedly installed on the front side of the front symmetrical plate 502, a round rod 504 rotatably connected between the two symmetrical plates 502 on opposite sides through a bearing, a fixed frame 505 sleeved on the outside of the round rod 504, a first movable frame 506 sleeved on the outside of the round rod 504, a second movable frame 507 sleeved on the outside of the round rod 504, a third movable frame 508 sleeved on the outside of the round rod 504, a sunshade curtain 509 bonded between the fixed frame 505, the first movable frame 506, the second movable frame 507 and the outside of the third movable frame 508, two limit plates 510 fixed to the right side of the third movable frame 508, and an ultraviolet sensor 511 fixedly installed on the top of the third movable frame 508.

[0047] It should be noted that the mounting frame 501 is located at the bottom of the pushing handle 216, and the pushing handle 216 extends to the left through the inner side of the fixed frame 505, so that the pushing handle 216 is not restricted by the fixed frame 505. The output shaft of the second drive mechanism 503 passes through the front side of the front symmetrical plate 502 and is fixedly connected to the front end of the round rod 504, so that the second drive mechanism 503 can drive the round rod 504 to rotate, wherein the first drive mechanism 410 and the second drive mechanism 503 are both composed of a servo motor and a reducer. The reducer can reduce the load of the servo motor, thereby enabling smooth transmission.

[0048] In addition, the fixed frame 505, the first movable frame 506, the second movable frame 507 and the third movable frame 508 are all frames with openings on the left and right sides and the bottom, and from the inside to the outside they are the fixed frame 505, the first movable frame 506, the second movable frame 507 and the third movable frame 508. The outer side of the fixed frame 505 is fixedly connected to the right side of the installation frame 501. The front sides of the first movable frame 506 and the second movable frame 507 are penetrated by the end of the round rod 504 and are rotatably connected to the outer side of the round rod 504 through bearings. The front side of the third movable frame 508 is penetrated by the end of the round rod 504 and is fixedly connected to the outer side of the round rod 504, so that the third movable frame 508 can rotate with the round rod 504, and then can pull the awning curtain 509 to open, and under the rotation of the first movable frame 506 and the second movable frame 507, it can be driven by the awning curtain 509 to rotate and open, thereby supporting the awning curtain 509.

[0049] At the same time, the side of the limiting plate 510 close to the fixed frame 505 extends to the right side of the first movable frame 506, so that the limiting plate 510 can push and limit the first movable frame 506 and the second movable frame 507 when the third movable frame 508 is retracted. The ultraviolet sensor 511 is connected to the signal of the visual control screen 303, which facilitates the use of the visual control screen 303 to play the role of overall control and reception.

[0050] It should also be noted that the electrical components appearing in the article are all electrically connected to the main controller and the adapter power supply 215. The provision of power is common knowledge in the field, and the adapter power supply 215 is a detachable and rechargeable power supply. The main controller can be a conventional known device such as a microcomputer that serves as a control. It can be implemented through simple programming by technicians in this field, and they are all existing publicly available power connection technologies and will not be described in detail in the article.

[0051] The working principle of the above embodiment is:

[0052] (1) When using a wheelchair for transportation, the walking wheel 211 is controlled by the visual control screen 303 so that it can move automatically, which is convenient for the user to move and relax outdoors. When the ultraviolet sensor 511 detects that the external ultraviolet rays are too strong, the visual control screen 303 sends a reminder to the user. At the same time, the voice receiving and releasing module 307 sends relevant voice when reminding, so that the user can clearly receive the reminder and then choose whether to open the awning curtain 509. When opening, the second driving mechanism 503 is started to drive the round rod 504 to rotate, thereby opening the third movable frame 508 and pulling the awning curtain 509 to open. In the process of opening the awning curtain 509, the second movable frame 507 and the first movable frame 506 are pulled to open, and the positions of the second movable frame 507 and the first movable frame 506 are positioned under the tension of the awning curtain 509, so that the awning curtain 509 can block the ultraviolet rays above the user's head, thereby improving the comfort when moving outdoors.

[0053] (2) By wearing the monitoring bracelet 305 on the hand, the user's heart rate can be monitored in real time. Under the action of the human infrared sensor 301, it can be detected in real time whether someone is approaching, and timely reminders can be given through the visual control screen 303 and the voice receiving and releasing module 307. The ultrasonic ranging sensor 302 can monitor obstacles in front of the wheelchair to prevent collisions. At the same time, the user can also control the wheelchair by speaking corresponding instructions to the voice receiving and releasing module 307, thereby improving the overall intelligence of the wheelchair.

[0054] (3) When standing or standing training is required, the user can use a preset voice command, such as "I need to stand up". After the voice is received by the voice receiving and releasing module 307, the electric push rod 401 is started to drive the push block 408 to move. The U-shaped block 405 can be driven to move by the limit of the two guide rods 407. At the same time, the first driving mechanism 410 drives the active rod 411 to rotate, so that the active shell 412 rotates downward. Under the transmission cooperation between the synchronous wheel 414 and the synchronous belt 415, the driven rod 413 is rotated, and then the corresponding gear 419 is driven to rotate through the linkage rod 417. Under the meshing transmission of the two gears 419, the transmission rod 418 is rotated, and then the swing block 420 and the driven shell 421 are driven to rotate. Since the rotation directions of the two are opposite after the meshing transmission of the gear 419, the driven shell 421 can be centered on the transmission rod 418. The user can then rotate the stand plate 403 downward to move the U-shaped block 405, the active shell 412 and the driven shell 421 downward, and let the support block 423 support the driven shell 421 instead of the adjusting wheel 427, so that the user can stably apply pressure perpendicular to the ground, and then stand steadily, and can also maintain this posture to directly complete the purpose of standing training.

[0055] Compared with the existing technology, the AI interactive wheelchair, through the coordinated use of the standing component and the AI interactive component, can use the AI interactive function to improve the intelligence of the wheelchair, and facilitate the user to stand stably. It can also directly perform standing training through the wheelchair, which improves the convenience of standing training. Since no other tools or personnel assistance are required during standing training, it can cultivate the user's psychology of independent standing training, reduce the workload of nursing staff, and facilitate users to perform efficient leg training. Through the AI interactive component, the user's entertainment when using the wheelchair can be improved, and AI can be used to directly query information such as weather, and simple conversations can be carried out, so that users are no longer bored when using the wheelchair. It also enables the user to sense and judge the people or objects around him while walking, thereby playing a protective role. At the same time, it can also monitor the user's heart rate and transmit it to the cloud for storage and sending, so that relevant personnel can grasp the user's status through the mini program. Through the sunshade component, it can also sense ultraviolet rays when the user moves outdoors, so as to remind the user whether it needs to be blocked, thereby improving the comfort when used outdoors, thereby further improving the user's actual experience and enabling him to have a better mood. It solves the problem that most existing wheelchairs only have conventional functions for special people to travel, which will lead to the low degree of intelligence of the wheelchair and it is inconvenient for users to directly use the wheelchair for standing training.
