[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 6The present invention provides a technical solution: a wheelchair that can prevent rollover, comprising a metal frame 1, a seat plate 2 and a back plate 3, the seat plate 2 is butted against the middle part of the inner wall of the metal frame 1, and the back plate 3 is connected to the top end of the inner wall of the metal frame 1, a flip foot pedal 4 is connected to the bottom end of the outer wall of the metal frame 1, and a handle 5 is sleeved on the top end of the outer wall of the metal frame 1, a breathable cushion 6 is connected to the top end of the seat plate 2, the bottom end of the metal frame 1 is connected to a universal front wheel 7 through a rotating seat, and a rear wheel 8 is connected to the side of the bottom end of the metal frame 1 away from the universal front wheel 7, and a support frame 9 is welded to the bottom end of the middle part of the metal frame 1. The metal frame 1 is connected to the flip pedal 4 by rotation, the fixed seat 13 is connected to the back plate 3 by sliding, and the fixed seat 13 and the limit plate 15 form an integrated structure; the threaded holes are evenly spaced on the back plate 3; the two sides of the outer wall of the metal frame 1 are connected to the bracket 10 through the fixing pin, and the top of the outer wall of the bracket 10 is connected to the handrail 11; one side of the outer wall of the bracket 10 is connected to the controller 12 through the mounting seat, and the support frame 9 is in an "X" shape; the top of the back plate 3 is connected to the fixed seat 13, and the internal thread of the fixed seat 13 is connected There is a threaded rod 14, and a threaded hole corresponding to the threaded rod 14 is opened on one side of the outer wall of the back plate 3; a limiting plate 15 is connected to the side of the fixing seat 13 away from the threaded rod 14, and the outer wall of the limiting plate 15 is slidably connected to the inner row plate 16; the inner row plate 16 is internally threadedly connected with threaded pins 17, and the threaded pins 17 are evenly spaced on the inner row plate 16; a fixing hole corresponding to the threaded pin 17 is opened inside the limiting plate 15, and a guide cavity corresponding to the limiting plate 15 is opened in the middle of the inner wall of the inner row plate 16; the fixing seat 13 is in a "C" shape.

[0023] In specific implementation, during the use of the wheelchair, since the outer wall of the support frame 9 is connected to the metal frame 1, the wheelchair is reinforced by the support frame 9, and then the foot pedal 4 is pushed and flipped to a horizontal state, and then the elderly is picked up and placed on the breathable cushion 6 of the seat plate 2. At this time, the breathable cushion 6 is used to improve the riding comfort and reduce the discomfort that may be caused by long-term use of the wheelchair. The breathable cushion 6 can effectively reduce the accumulation of heat and moisture, avoid skin damage when sitting for a long time, and also help reduce the risk of pressure sores. Then, the elderly is supported and his back is leaned against the backboard 3, and the backboard 3 is used to provide auxiliary support for the elderly;

[0024] Since the metal frame 1 is connected to the armrest 11 through the bracket 10, the elderly person then puts his arm on the armrest 11, which provides additional support and balance for the elderly person, helping the elderly person to stay stable during the ride and prevent accidental slipping or imbalance. After that, the elderly person can control the universal front wheel 7 and the rear wheel 8 through the controller 12, so that the wheelchair drives the elderly person forward, or a family member holds the handle 5 to push the wheelchair to drive the elderly person forward;

[0025] In order to provide better support for the elderly, first dock the interior of the fixed seat 13 with the back plate 3. Since the fixed seat 13 is connected to the limiting plate 15, the movement of the fixed seat 13 will drive the limiting plate 15 to move together. Then manually rotate the threaded rod 14 until the threaded rod 14 penetrates the fixed seat 13 and docks with the back plate 3, thereby limiting the fixed seat 13 to prevent the fixed seat 13 from moving at will. Then, connect the inner row plate 16 with the limiting plate 15 from top to bottom, and then rotate the threaded rod 14 to penetrate the limiting plate 15, and then limit the inner row plate 16 to prevent the inner row plate 16 from moving at will.

[0026] Then, the inner row of plates 16 assists the wheelchair to maintain balance during movement, and when the wheelchair moves or changes direction, the inner row of plates 16 provides additional lateral support when the wheelchair turns to prevent rollover, thereby providing a limit for the body of the elderly, and providing a lateral support force, thereby preventing the elderly's upper body from leaving the backrest due to the turning or bumping of the wheelchair, thereby causing lateral collision injuries to the elderly, thereby providing more stable support and reducing the risk of wheelchair rollover, especially when the elderly turn or move on uneven ground, the lateral inner row of plates 16 helps to improve the overall structural stability of the wheelchair, thereby playing a role in facilitating stable support and preventing rollover when the wheelchair is in use;

[0027] As the use time increases, when the outer wall of the inner row plate 16 becomes dirty or damaged and needs to be replaced, the threaded pin 17 is first rotated to disconnect the limit plate 15, thereby canceling the limit of the inner row plate 16. Since the inner row plate 16 and the limit plate 15 are slidably connected, at this time, only the limit plate 15 needs to be moved upward to be removed for replacement;

[0028] Because the outer wall of the back panel 3 is provided with threaded holes corresponding to the threaded rods 14, and the threaded holes are evenly spaced on the back panel 3, family members can first rotate the threaded rods 14 to disconnect the back panel 3, thereby canceling the limit between the back panel 3 and the fixing seat 13, and then move the fixing seat 13 to drive the inner row of panels 16 to move, thereby changing the distance between the inner row of panels 16 until the inner row of panels 16 move to the specified position, and then rotate the threaded rods 14 to connect with the corresponding threaded holes, thereby limiting the fixing seat 13, so that the distance between the inner row of panels 16 corresponds to the usage habits of the elderly, thereby facilitating people to adjust the position of the inner row of panels 16.

[0029] To sum up, when the wheelchair that can prevent rollover is used, after the elderly is placed on the wheelchair, the universal front wheel 7 and the rear wheel 8 and other components are controlled by the controller 12, so that the universal front wheel 7 and the rear wheel 8 rotate, so that the wheelchair drives the elderly forward, and provides adjustment functions for various parts of the wheelchair, so as to make personalized adjustments according to the specific needs of the elderly. This is the existing technology and will not be elaborated on here. By adding the inner row of plates 16, the overall structural stability of the wheelchair is improved, the risk of the wheelchair rollover is reduced, and when the wheelchair turns, the inner row of plates 16 provide lateral support force, thereby preventing the elderly's upper body from leaving the backrest due to the turning or bumping of the wheelchair, thereby causing lateral collision injuries to the elderly. In addition, this solution does not use physical devices to prevent the entire wheelchair from falling sideways, but uses the lateral inner row of plates 16 to provide a limit for the elderly's body. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
