Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multifunctional wheelchair with a gyroscope. Background Technology

[0002] With the arrival of an aging society and the increase in the number of people with disabilities, the demand for wheelchairs, as an important assistive tool for people with mobility impairments, is constantly growing. However, existing wheelchair technology still has many shortcomings in terms of functionality and user experience, making it difficult to meet the needs of users in diverse scenarios.

[0003] First, most existing wheelchairs have limited functions, focusing only on stability and anti-tipping features, lacking multi-functional integration. Users cannot achieve comfortable posture adjustments when resting or sleeping, limiting the user experience. Second, while many folding wheelchairs have improved portability and storage convenience, their folded function remains limited, serving only as a means of transportation and unable to be converted into a bed or other multi-functional device. Furthermore, existing wheelchairs generally lack dynamic stability systems. When on uneven surfaces or when accidentally tilted, there is no effective posture adjustment mechanism, making them prone to tipping over and posing safety hazards to users.

[0004] In the existing technology, existing wheelchairs cannot maintain overall stability by dynamically adjusting the posture of each component when tilted, which is particularly inadequate in complex terrain or in emergency situations.

[0005] In summary, this utility model addresses these shortcomings by proposing a multifunctional wheelchair with a gyroscope. Through innovative design and functional integration, it significantly improves the stability and ease of use of the wheelchair. Utility Model Content

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0035] Example

[0036] This embodiment provides a multifunctional wheelchair with a gyroscope, including: a seat 1, a backrest 2 hinged to the rear side of the seat 1, a pedal mechanism 3 hinged to the front side of the seat 1, and a drive motor 9.

[0037] The seat 1 includes: a seat body, a fixing frame 8 fixedly disposed at the bottom of the seat body, and armrests 4 fixedly disposed on both sides of the top of the fixing frame 8;

[0038] The drive motor 9 is fixedly installed in the fixed frame 8. The first wheel 5 and the universal wheel 6 are respectively connected to the two sides of the fixed frame 8 by rotating shafts. The universal wheel 6 can turn flexibly and, together with the first wheel 5, enables the wheelchair to change its direction of travel flexibly. A rotating rod motor 23 is fixedly installed on the rear side of the fixed frame 8. The output end of the drive motor 9 is rotatably connected to the first wheel 5 through a transmission shaft.

[0039] Among them, pushers 7 are fixedly installed on the top two sides of the backrest 2, and a rotating motor 71 is fixedly installed on one side of each pusher 7. A lifting rod 72 is fixedly installed at the output end of the rotating motor 71. A second wheel 73 is connected to the bottom shaft of the lifting rod 72. A sliding plate 21 is fixedly installed on the rear side of the backrest 2. A sliding groove is opened on the sliding plate 21. A slider 22 is slidably installed in the sliding groove. A rotating rod 24 is hinged to the slider 22. The end of the rotating rod 24 away from the slider 22 is fixedly connected to the output shaft of the rotating rod motor 23.

[0040] The armrest 4 is fixedly equipped with a controller 13, which is used to control various functions of the wheelchair. The mounting frame 8 is fixedly equipped with a charging power supply, which supplies power to the electrical equipment of the wheelchair. The bottom of the seat body and the backrest 2 are respectively fixedly equipped with gyroscopes. The charging power supply is electrically connected to the controller 13. The controller 13 is electrically connected to the gyroscope, the rotating motor 71, the drive motor 9, the rotating rod motor 23, and the lifting rod 72.

[0041] The pedal mechanism 3 includes: a foot pedal 31, a connecting rod 32, and a foot pedal back plate 33;

[0042] The top of the connecting rod 32 is hinged to the front end of the seat 1, and the foot pedal 31 is fixedly mounted on the bottom of the connecting rod 32.

[0043] The surface of the foot pedal 31 is provided with anti-slip texture to prevent the user's foot from slipping;

[0044] An electric adjustment push rod 11 is hinged to one side of the connecting rod 32. The end of the electric adjustment push rod 11 away from the connecting rod 32 is fixedly set on the front side of the fixed frame 8. The electric adjustment push rod 11 is electrically connected to the controller 13. The electric adjustment push rod 11 can adjust the angle of the pedal mechanism 3 according to the command.

[0045] The connecting rod 32 includes: a straight rod 321 and an "L"-shaped rod 322;

[0046] The straight rod 321 has a cavity inside, and the top of the "L"-shaped rod 322 is slidably disposed in the cavity;

[0047] The straight rod 321 has several first through holes on its side wall, and the through holes communicate with the cavity. The L-shaped rod 322 has a second through hole fixedly provided on one side, and the diameters of the first through holes and the second through holes are the same.

[0048] The top of the “L”-shaped rod 322 is confined in the cavity by the first through hole and the second through hole and the bolt, thereby adjusting the length of the connecting rod 32.

[0049] The backrest panel 2 is also fixedly equipped with foldable guardrails 10 on both sides. The foldable guardrails 10 are arranged parallel to the backrest panel 2. When in use, the guardrails 10 can be opened to ensure the safety of the user. When not in use, they can be folded parallel to the backrest panel 2 to save space.

[0050] A neck pillow 12 is fixedly installed on the top front side of the backrest 2.

[0051] As a preferred implementation, the gyroscope is a MEMS gyroscope.

[0052] In a preferred embodiment, the drive motor 9 is a three-phase asynchronous motor.

[0053] In a preferred embodiment, the rotating rod motor 23 and the rotating motor 71 are stepper motors.

[0054] As a preferred embodiment, the lifting rod 72 is a DT series electric actuator.

[0055] In a preferred embodiment, the electric adjusting push rod 11 has a built-in displacement sensor, which is electrically connected to the controller 13. The displacement sensor can accurately feed back the displacement information of the electric adjusting push rod 11, which facilitates precise control by the controller 13.

[0056] In a preferred embodiment, the drive motor 9 is fixedly mounted in the mounting frame 8. Its output end drives the drive shaft to rotate via gear transmission. The drive shaft then meshes with the wheel axle gears of the two first wheels 5 to transmit power and drive the first wheels 5 to rotate.

[0057] In a preferred embodiment, the controller 13 is equipped with a wheelchair reset button and a bed reset button to control the gyroscope, the rotary motor 71, the drive motor 9, the rotating rod motor 23, the lifting rod 72, and the electric adjustment push rod 11.

[0058] When in use, when the wheelchair is started, the drive motor 9 starts working as a power source. The drive motor 9 drives the first wheel through the transmission shaft, thereby driving the first wheel to rotate smoothly. The omnidirectional wheel 6 ensures the steering of the wheelchair.

[0059] Regarding the adjustment of the backrest angle, the rotating rod motor 23 starts to operate after receiving the command. The rotation of its output shaft drives the rotating rod 24 to rotate synchronously. The slider 22 at the end of the rotating rod 24 is pulled by the movement of the rotating rod and slides linearly in the preset groove of the slide plate 21. Since the slider 22 is connected to the backrest 2 by a hinge, the linear displacement of the slider 22 is converted into the rotation of the backrest 2 around the hinge point, thereby realizing the forward or backward angle adjustment of the backrest 2 to meet the different leaning needs of the user.

[0060] Regarding the operation of the second wheel 73, after the rotation motor 71 on the pusher 7 is started, it drives the lifting rod 72 connected to it to start rotating. When the lifting rod 72 rotates to a preset appropriate angle, the drive component inside the lifting rod 72 starts to work, pushing the second wheel 73 to perform vertical lifting and lowering movements until the second wheel 73 smoothly contacts the ground, providing an additional support point for the wheelchair and enhancing stability.

[0061] The angle adjustment of the pedal mechanism 3 is accomplished by the electric adjustment push rod 11. During operation, the foldable guardrail 10 is first opened to ensure user safety. Then, the electric adjustment push rod 11 extends or retracts according to the command issued by the controller 13. One end of the electric adjustment push rod 11 is hinged to the connecting rod 32, and the other end is fixed to the fixed frame 8. Its extension and retraction movement is transmitted to the connecting rod 32 through the hinge point, causing the connecting rod 32 to rotate around the hinge point with the front end of the seat 1, thereby driving the foot pedal 31 to achieve angle adjustment.

[0062] The controller 13 plays a core control role in the entire system. It is equipped with wheelchair mode reset buttons and bed mode reset buttons. The operator inputs mode switching commands to the controller 13 by pressing the corresponding buttons. At the same time, the controller 13 continuously receives real-time posture data from the gyroscopes at the bottom of the seat body and backrest 2. After the data is processed and precisely calculated by the internal algorithm of the controller 13, the controller 13 automatically sends precise control signals to the rotary motor 71, drive motor 9, rotary rod motor 23, lifting rod 72, and electric adjustment push rod 11 to coordinate and adjust the operating status of each component. For example, during the transition from wheelchair mode to bed mode, the controller 13, based on algorithm analysis, gradually adjusts the backrest 2 to tilt backward to a suitable angle, while simultaneously adjusting the pedal mechanism 3 to lift upward at a certain angle, and the second wheel 73 lowers to contact the ground and provide support. All components work closely together to accurately complete the transition from wheelchair to bed mode.

[0063] In summary, this invention, by integrating a gyroscope and controller, enables the wheelchair to monitor and adjust its posture in real time, ensuring stability on uneven surfaces or when tilted, significantly improving user safety. The adjustability of the backrest and pedal mechanism provides diverse comfortable posture options. Through the coordinated operation of the electric adjustment lever and lifting rod, the various components (such as the backrest, pedal mechanism, and second wheels) can transform the wheelchair into a bed position, meeting the user's needs for rest, sleep, and other scenarios. The controller integrates multiple functional modules, allowing for mode switching and posture adjustment through simple button operation, simplifying operation and enhancing the user experience.

[0064] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
