Description

Technical Field

[0001] The utility model relates to the technical field of walking aids, in particular to a wheeled mobile device for assisting in supporting the human body. Background Art

[0002] In the field of medical auxiliary devices, traditional walking aids have always been favored by patients or the elderly with inconvenient legs and feet for their stability and practicality. These walking aids are usually equipped with a seat function, enabling users to have a comfortable resting place when walking for a long time or in need of rest, effectively reducing the fatigue caused by walking.

[0003] However, the armrests of traditional walking aids are usually fixed and cannot be adjusted according to the different postures and needs of users. This may cause some inconvenience to users, especially during the process of changing from a standing position to a sitting position.

[0004] When a user needs to switch from a standing position to a sitting position, if the position of the armrest is too high, they may need to exert extra effort to lower their body, which not only increases the operation difficulty but also may increase the risk of accidental falls. On the contrary, if the armrest position is too low, the user may need to bend down or twist their body to comfortably hold the armrest, which will not only affect their sitting comfort but also may cause unnecessary pressure on their spine and joints.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is more than two.

[0043] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "splicing", "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0044] The following combines Figures 1 to 6 to describe a wheeled mobile device for assisting in supporting the human body according to an embodiment of the present utility model.

[0045] A wheeled mobile device for assisting in supporting the human body, comprising a bottom rod 1, a mounting plate 2 and a seat cushion 3. The two bottom rods 1 are parallel to each other. The two mounting plates 2 are respectively vertically mounted on the side walls of the bottom rods 1. The two mounting plates 2 are arranged opposite to each other. The two sides of the seat cushion 3 are respectively connected to the two mounting plates 2;

[0046] Lifting mechanisms 4 are fixedly installed on both of the bottom rods 1. The driving ends of the lifting mechanisms 4 are connected to the corresponding mounting plates 2;

[0047] Armrest mechanisms 5 are rotatably installed at the tops of the two mounting plates 2. The armrest mechanisms 5 are used to support the human body;

[0048] A folding mechanism 6 is provided between the two bottom rods 1. The two ends of the folding mechanism 6 are horizontally connected to the two bottom rods 1. The folding mechanism 6 is used to adjust the distance between the two bottom rods 1;

[0049] Movable wheels 8 and braking mechanisms 7 are provided at the bottoms of the two bottom rods 1. The braking mechanisms 7 are used to limit the rolling of the movable wheels 8.

[0050] In the wheeled mobile device for assisting in supporting the human body of this solution, the driving end of the lifting mechanism 4 is connected to the mounting plate 2, so that the mounting plate 2 can drive the seat cushion 3 and the armrest mechanism 5 to lift together.

[0051] Therefore, when the user is in a sitting position, the lifting mechanism 4 is started. The lifting mechanism 4 drives the mounting plate 2 downward, and the mounting plate 2 drives the seat cushion 3 and the armrest mechanism 5 downward. Among them, the user can adjust the height of the mounting plate 2 according to his own height, so that the seat cushion 3 can provide rest support for the user, and the armrest mechanism 5 can support the human body, greatly improving the practicability and comfort of the walking aid.

[0052] When the user changes to a standing position, the lifting mechanism 4 is continued to be started, so that the mounting plate 2, the seat cushion 3 and the armrest move upward together. At this time, the heights of the seat cushion 3 and the armrest mechanism 5 change. The seat cushion 3 can provide support for the user's legs, and the armrest can continue to support the human body, solving the problem that the armrests of traditional walking aids are usually fixed and cannot be adjusted according to the different postures and needs of users.

[0053] The arrangement of the movable wheels 8 and the braking mechanisms 7 at the bottom of the bottom rod 1 makes the walking aid more flexible when moving, and can also quickly fix the position when needed to prevent slipping or accidental movement. This design not only ensures the convenience of the walking aid, but also improves its safety in use.

[0054] It should be noted that the movable wheels 8 are preferably universal wheels, and universal wheels are provided at both ends of the bottom rod 1, which can ensure that the wheeled mobile device of this solution can move in multiple angles and directions, reducing the physical consumption and time waste of users.

[0055] In addition, the folding mechanism 6 provided between the two bottom rods 1 can facilitate users to adjust the distance between the two bottom rods 1 according to needs. This design not only makes the walking aid more convenient for storage and carrying, but also can be flexibly adjusted according to the user's walking environment or space limitations during use, further enhancing the practicality and convenience of the walking aid.

[0056] The lifting mechanism 4 includes a power member 41, a first lifting link 42, a second lifting link 43, and a lifting plate 44. The lifting plate 44 is vertically installed on the bottom rod 1. The head end of the first lifting link 42 is rotatably connected to the bottom of the lifting plate 44, and the tail end of the first lifting link 42 is rotatably connected to the bottom of the mounting plate 2;

[0057] The head end of the second lifting link 43 is rotatably connected to the top of the lifting plate 44, and the tail end of the second lifting link 43 is fixedly connected to the top of the mounting plate 2. The first lifting link 42 and the second lifting link 43 are parallel to each other;

[0058] A convex portion 45 is provided at the head end of the first lifting link 42. The mounting end of the power member 41 is rotatably installed on the bottom rod 1, and the driving end of the power member 41 is rotatably installed on the convex portion 45.

[0059] Among them, the head end and the tail end of the first lifting link 42, and the head end and the tail end of the second lifting link 43 are connected to form a parallelogram at the four end points, ensuring the stability of the lifting plate 44 during the lifting process, enabling the lifting plate 44 to maintain a stable lifting trajectory, and avoiding operation errors or damages caused by shaking or tilting. The power member 41 is a cylinder. When the power member 41 is started, since the power member 41 is hinged to the convex portion 45, the power member 41 can drive the convex portion 45 to start rotating with the head end of the second lifting link 43 as the origin. At this time, the convex portion 45 and the first lifting link 42 are integrally formed, so that the first lifting link 42 starts to rotate under the drive of the convex portion 45, and the second lifting link 43 rotates together, making the lifting action of the lifting plate 44 more direct and efficient, effectively reducing the energy loss of the power member 41 and improving the lifting efficiency.

[0060] The armrest mechanism 5 includes an armrest main body 51, a first support link 52, a second support link 53, and a support limiting component 54;

[0061] Both ends of the first support link 52 are respectively connected to the mounting plate 2 and the armrest main body 51. The bottom and top of the second support link 53 are respectively connected to the mounting plate 2 and the armrest main body 51. The first support link 52 and the second support link 53 are parallel to each other. The armrest main body 51 is provided with a support limiting component 54, and the support limiting component 54 is used to limit the rotation of the first support link 52.

[0062] It should be noted that the first end and the second end of the first support link 52, and the first end and the second end of the second support link 53, the four end points are connected to form a parallelogram. Therefore, by simply rotating the first support link 52 and the second support link 53, the height of the armrest main body 51 can be quickly adjusted, which not only reduces the operation difficulty and the safety risks caused by complex operations, but also ensures that the user can obtain the best support when operating the wheelchair or equipment.

[0063] When the armrest main body 51 is adjusted to a suitable height, the support limiting component 54 can limit the rotation of the first support link 52, thereby ensuring that the armrest main body 51 remains stable during use, making the wheeled mobile device of this solution more stable during driving.

[0064] The support limiting component 54 includes a spring limit pin 541, a limit groove 542 and an adjustment dial 543. The top of the first support link 52 is provided with a sector-shaped limit portion 544. The spring 74 limit pin 541 includes an elastic ring 545 and a pin 546. One end of the elastic ring 545 is fixedly connected to the pin 546. The other end of the pin 546 passes through the limit groove 542 and is movably clamped with one end of the sector-shaped limit portion 544. The adjustment dial 543 is eccentrically rotatably installed on the armrest. The adjustment dial 543 is provided with a connecting rod 547, and the connecting rod 547 is located inside the elastic ring 545.

[0065] Through the design of the adjustment dial 543, the user can conveniently control the position of the pin 546 of the spring 74 limit pin 541 in the limit groove 542. The adjustment dial 543 is eccentrically rotatably installed on the armrest main body 51. The user can directly adjust the position of the connecting rod 547 on the elastic ring 545 by rotating the adjustment dial 543, and then drive the elastic ring 545 and the pin 546 to move, so that the pin 546 moves flexibly and stably in the limit groove 542 and is separated from the sector-shaped limit portion 544, so that the first support link 52 can rotate freely.

[0066] After the user releases the adjustment dial 543, the elastic ring 545 has good deformation recovery ability, enabling the elastic ring 545 to drive the connecting rod 547 and the latch 546 to move back to their original positions. At this time, the latch 546 is engaged with one end of the sector-shaped limiting portion 544, and the latch 546 can accurately lock the inclination angle of the current first support link 52, thereby ensuring that the entire armrest mechanism 5 can be stably positioned at a specific position when needed, enhancing the stability and safety of the armrest mechanism 5.

[0067] The design of the spring 74 limit pin 541 can quickly respond when the support link moves or shakes unexpectedly, preventing further instability or damage through the engagement of the latch 546 with the sector-shaped limiting portion 544, helping to reduce the potential risks and damages of this wheeled mobile device and ensuring the safety of the user during operation.

[0068] A brake handle 71 is provided at the front end of the armrest main body 51, and the brake mechanism 7 includes a brake wire, a paddle 73, a spring 74, and a brake shaft 72;

[0069] The brake handle 71 is fixedly connected to the head end of the brake wire. The paddle 73 is rotatably installed on the inner wall of the bottom rod 1. One end of the paddle 73 is connected to the tail end of the brake wire, the other end of the paddle 73 is rotatably connected to the top of the brake shaft 72. The bottom of the brake shaft 72 extends out of the bottom rod 1, and the bottom of the brake shaft 72 is movably abutted against the moving wheel 8. A spring 74 is provided around the brake shaft 72. The top of the spring 74 is fixedly connected to the top of the brake shaft 72, and the bottom of the spring 74 is fixedly connected to the bottom wall of the bottom rod 1.

[0070] By providing the brake handle 71 at the front end of the armrest main body 51, the user can more conveniently control the braking action. Especially in an emergency, the moving wheel 8 can be quickly and effectively stopped from rotating, thus ensuring the safety of the user.

[0071] It should be noted that a brake shaft seat is provided on the bottom rod 1, and the brake shaft seat is installed between the brake shaft 75 and the bottom rod. The brake handle 71 is fixedly connected to the head end of the brake wire, so that the user only needs to gently pull the brake handle 71, causing the end of the paddle 73 close to the brake wire to be subjected to an upward pulling force, making the end of the paddle 73 close to the brake shaft 72 press down on the brake shaft 72 downward. The brake shaft 75 is pressed downward, and the external spline shape feature on the lower side of the top flange thereof will come into contact with the internal spline feature of the brake shaft seat, thereby restricting the relative rotation between the brake shaft seat and the brake shaft 75, and then restricting the rotation of the moving wheel 8 in the vertical axis direction, thus achieving the braking effect.

[0072] When the user releases the brake handle 71, the spring 74 drives the brake shaft 72 to reset, enabling the brake mechanism 7 to quickly rebound after braking, avoiding wear of the moving wheel 8 caused by long-term braking and deterioration of the user experience. At the same time, the buffering effect of the spring 74 also makes the braking process smoother, enhancing the comfort of use.

[0073] The folding mechanism 6 includes a first folding rod 61, a second folding rod 62, a folding handle 63, and a third folding rod 64;

[0074] The folding handle 63 is vertically located between the two bottom rods 1. There are two first folding rods 61 and two second folding rods 62. One end of each of the two first folding rods 61 is rotatably connected to the top of the folding handle 63, and the other end of each of the two first folding rods 61 is rotatably connected to the top of the corresponding lifting plate 44. One end of each of the two second folding rods 62 is rotatably connected to the bottom of the folding handle 63, and the other end of each of the two second folding rods 62 is rotatably connected to the bottom of the corresponding lifting plate 44. The first folding rod 61 and the second folding rod 62 are parallel to each other;

[0075] The folding handle 63 is provided with a vertical chute 65. There are two third folding rods 64. One end of each of the two third folding rods 64 is slidably connected to the chute 65, and the other end of each of the two third folding rods 64 is rotatably connected to the bottom of the corresponding lifting plate 44.

[0076] The setting of the folding mechanism 6 enables the wheeled mobile device of this solution to maintain good stability during folding and unfolding, effectively preventing shaking and accidental folding. Moreover, when the lifting plate 44 is in the folded state, the space occupied by the entire mechanism is greatly reduced, effectively improving the space utilization rate.

[0077] Vertically pull up the folding handle 63 and simultaneously press the two ends of the bottom rod 1 inward, causing the first folding rod 61 and the second folding rod 62 to tilt upward, and the end of the third folding rod 64 close to the chute 65 to tilt downward, thus conveniently and quickly completing the folding process of the wheeled mobile device of this solution.

[0078] Vertically press down the folding handle 63 and simultaneously pull the bottom rod 1 outward, which can cause the first folding rod 61 and the second folding rod 62 to tilt downward and then be in a horizontal state. At this time, the end of the third folding rod 64 close to the chute 65 tilts upward until one end of the third folding rod 64 is located at the top of the chute 65, and then the wheeled mobile device of this solution can be easily unfolded.

[0079] The folding mechanism 6 further includes a first base link 66, a second base link 67, a base 68, and a third base link 69;

[0080] There are two second base linkages 67 and third base linkages 69. One ends of the two second base linkages 67 are respectively rotatably connected to the bottom of the first base linkage 66, and the other ends of the two second base linkages 67 are respectively rotatably connected to the opposite mounting plates 2. The mutually approaching ends of the two third base linkages 69 are hinged to each other, and the mutually remote ends of the two third base linkages 69 are respectively rotatably connected to the opposite mounting plates 2. The top of the first base linkage 66 is rotatably connected to the base 68;

[0081] One end of the base 68 is hinged to the opposite mounting plate 2, and the other mounting plate 2 is provided with a snap structure. The other end of the base 68 is snap-connected to the other opposite mounting plate 2. The seat cushion 3 is detachably mounted on the base 68.

[0082] It should be noted that one end of the base 68 is hinged to the opposite mounting plate 2, and the other end is snap-connected to the opposite mounting plate 2. During the folding process, both of the two second base linkages 67 are tilted upward, which can drive the first base linkage 66 to move upward, so that the end of the base 68 is tilted upward, effectively avoiding the situation that the base 68 cannot be disassembled, resulting in the inability to fold the wheeled mobile device.

[0083] In addition, the folding mechanism 6 is also provided with a third base linkage 69. The third base linkage 69 can improve the stability of the folding mechanism 6 during folding and unfolding, effectively preventing shaking and accidental folding, and improving the safety of use.

[0084] The front end of the bottom rod 1 is provided with a footrest 11. When the user's foot is placed on the footrest 11, it can increase the comfort of the user and also help improve the overall stability of the wheeled mobile device, reducing accidents caused by leg shaking.

[0085] Both of the two mounting plates 2 are provided with vertical mounting rods 21. The backrest 22 and the safety belt 23 are arranged on the two mounting rods 21, and a walking assist handle 24 is arranged at the top of the mounting rod 21.

[0086] It should be noted that the mounting rod 21 is fixedly connected to the mounting plate 2. Therefore, the mounting rod 21 rises and falls together with the mounting plate 2, so that the backrest 22 and the safety belt 23 can rise and fall together, providing a supporting effect for the sitting and standing postures of the user.

[0087] The backrest 22 provides back support for the user, enabling the user to maintain a comfortable posture during use. Whether sitting or standing, the backrest 22 can effectively relieve the pressure on the back and reduce the sense of fatigue.

[0088] The safety belt 23 provides additional safety protection for the user, allowing the user to always maintain a relative position with the seat cushion 3, thereby ensuring that the user's center of gravity is always in the device, preventing falls and rollovers caused by body tilt or accidents, and greatly increasing safety during use.

[0089] The seat cushion 3 is a T-shaped structure. When sitting, the T-shaped seat cushion 3 can evenly distribute the weight of the body and reduce the pressure on the buttocks and legs. When the user stands, the side parts of the T-shaped structure can play a role of avoiding air, so that the user can easily switch between sitting and standing positions.

[0090] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
