Description
Technical Field
[0001] The utility model relates to the technical field of electric wheelchairs, in particular to an electric wheelchair capable of standing and walking. Background Art
[0002] With the development of society and the improvement of people's living standards, more and more disabled people are using multifunctional wheelchairs. At present, it is difficult for people with lower limb disabilities living in rural areas to buy suitable wheelchairs in the market. Because most of the roads in rural areas are dirt roads with potholes, it is a luxury to go out for a walk. They will be trapped at home all the time. Due to long-term sitting, they will also suffer from bedsores, urinary tract infections and other diseases many times, which will cause serious harm and trouble to the body and life. This is also a common phenomenon among disabled people in China. Many disabled people dream of having a multifunctional wheelchair that can be walked while sitting or standing, and is easy to take away when traveling, so as to reduce bedsores and urinary tract infections, facilitate their work and life, and reduce the burden of family care.
[0003] However, the electric standing wheelchairs on the market cannot stand and walk well on rural roads. Most wheelchairs are not convenient for walking on bumpy roads due to the small wheels installed in the front. Garbage and other things are easily scraped under the small wheels, making it inconvenient to overcome obstacles. Moreover, they are not easy to carry away and are heavy and difficult to disassemble. The body of the wheelchair is too long when standing and is not flexible when walking indoors. Some wheelchairs can stand but not walk, which is not very convenient for the work and life of wheelchair users.
[0004] China Authorization Announcement No. CN 211382258 U, the authorization announcement date is September 1, 2020, which discloses a multi-mode intelligent wheelchair lifting mechanism equipped with a flexible exoskeleton suit, including an upward inclined drive unit, a lead screw, an H-shaped mobile platform, a guide rail, an inclined small arm, a lifting large arm, a base drive unit, a lifting platform, a front drive unit, a slide bracket slide, a leg support and a telescopic pedal. This application can be switched to a horizontal posture mode for patients with walking disabilities to perform passive rehabilitation training in a lying position in the early stage of muscle weakness rehabilitation; it can also be switched to a normal wheelchair sitting mode for patients to walk and realize a convenient life for patients; it can also be switched to a horizontal lifting mode of the chair surface, adjusting the lifting height and angle of the chair surface to help users take and put high objects; it can also be switched to an auxiliary support standing mode, so that the chair surface is flipped forward to present a standing posture, supporting patients in the late stage of rehabilitation, and leaving the wheelchair for ground rehabilitation training with the help of a sensitive cane and a flexible exoskeleton suit. Therefore, it has the characteristics of comprehensive functions and convenient use. The defect of the prior art is that when the user changes from a sitting posture to a standing posture, for safety reasons, the user still needs to get out of the wheelchair and wait until the wheelchair completes the posture change before returning to the wheelchair for continued use. For some users whose physical fitness ensures that they are not convenient for standing, such a structure still requires the assistance of others to complete the standing posture, which greatly reduces the convenience of the user. In view of this situation, it is urgent to improve. Utility Model Content

Through such a structural setting, the strength of the universal wheel bracket 32 is enhanced and the service life of the structure is improved.
[0045] The operation steps of posture transformation in this embodiment are:
[0046] 1. Fasten the knee pad 28 and output the posture change instruction through the controller 14;
[0047] 2. The power output of the electric push rod 22 causes the connecting rod 45 to drive the motor fixing plate 33, the driving motor 41, and the driving wheel 17 to move forward a predetermined distance. At the same time, the movable arm 23 synchronously drives the guide rail slider 24 to move in the reverse direction a predetermined distance through the sliding rod 34 and then stops;
[0048] 3. Adjust the tension bolt 50 to turn the backrest 11 and the armrest 12 synchronously by 90°;
[0049] 4. The power output of the electric push rod 26 of the seat cushion drives the rear cross beam 29 to flip 90 degrees, and the backrest and the armrest frame rotate synchronously, so that the backrest, the seat cushion and the chassis frame assembly form a vertical relationship, that is, the change of the standing posture is completed.
[0050] This implementation can drive itself in the forward direction. It first increases the length of the vehicle and improves safety when changing postures, so that users can stand up without leaving the wheelchair and without the help of external forces, allowing disabled people to better integrate into society and experience the joy of work and life. Standing can also bring health to the body. Moreover, after repeated calculations and a large number of computer simulation certifications, the movement trajectory of the wheelchair when standing is consistent with the movement trajectory of the normal human body. The design is ingenious, scientific and reasonable, which greatly improves the practicality of the wheelchair.
[0051] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
