Description

TECHNICAL FIELD

[0001] The utility model relates to an auxiliary moving device, in particular to an old person auxiliary moving device for the aged, belongs to the technical field of old person auxiliary moving equipment. BACKGROUND

[0002] With the acceleration of the aging society, the old person auxiliary device becomes the important tool for improving the life quality of the old people. In the field of the old person auxiliary moving equipment, the prior art is mostly concentrated on the single function realization, and it is difficult to take into account the dual needs of walking support and temporary rest.

[0003] In the prior art, such as the walking auxiliary device with variable mode disclosed by the announcement number CN210844114U, the telescopic frame is controlled by the electric push rod to realize the conversion of the seat and the walking function. The device can realize the mode change, but it depends on the electric drive, and cannot be used when there is no electricity or the motor fails. Moreover, the mechanical structure is relatively complex, which increases the manufacturing cost and the failure rate. For the old people who need quick response and simple operation, the applicability is limited. For example, the old person walking intelligent auxiliary guiding mobile robot disclosed by the publication number CN111166631A enhances the use stability through the symmetrical adjustment mechanism and the protection mechanism. The design considers the protection during walking, but the folding plate and other seat components are usually external and are not integrated in the frame body, which leads to the structure protruding during storage, affecting the flexibility of the device movement, and may become a stumbling hazard during walking. In addition, the above-mentioned existing device has obvious deficiency in structure lightening. Most walking aids use solid metal materials to ensure the bearing strength, which leads to the overall weight being too large, and the old people or nursing staff move and operate very hard. When the state of the device with the sitting function is switched, the user needs to make a large body position adjustment or completely leave the support range, which is not only inconvenient to operate, but also brings the risk of imbalance and falling. Moreover, the movable parts and the fixed frame body of the existing walking aid often lack effective guiding and limiting mechanism. For example, there is a shaking gap between the telescopic rod and the sleeve, which is easy to produce structure instability during bearing or moving. The locking mechanism of the folding plate after unfolding often relies on the simple latch or hook, and the connection firmness is insufficient, and it is easy to interfere with other objects when not collected. These structural defects make the existing device have low reliability and poor user experience when realizing the seamless conversion of walking and sitting rest functions. UTILITY MODEL CONTENTS

[0035] Embodiment two

[0036] Improved on the basis of embodiment one:

[0037] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , the arc-shaped supporting rods 11 of the movable frame assembly 1 are arranged in layers from top to bottom, three arc-shaped supporting rods 11 are arranged in each layer, the front ends of adjacent arc-shaped supporting rods 11 are fixedly connected with front end support rods 17 arranged vertically, the tail ends of the upper and middle layers of arc-shaped supporting rods 11 are fixedly connected with tail end support plates 13 arranged vertically, and the tail ends of the middle and lower layers of arc-shaped supporting rods 11 are fixedly connected with tail end support rods 15 arranged vertically. The layered design enhances the overall stability of the movable frame assembly 1, and the distribution of multiple arc-shaped supporting rods 11 optimizes the stress points, making the device more evenly distribute pressure when supporting the weight of the elderly, reducing the risk of deformation caused by local stress concentration. The front end support rods 17 help the elderly to hold on and maintain balance when in the auxiliary moving state, while ensuring that the front ends of the two groups of movable frame assemblies 1 are more firmly connected, preventing accidental separation during use. The tail end support plates 13 not only provide a basis for the installation of the folding plate assembly 3, but also serve as docking points when switching states, enhancing the continuity of the structure. The tail end support rods 15 bear the main supporting load when in the auxiliary sitting state, ensuring that the folding plate assembly 3 can stably support the weight after being unfolded, avoiding seat shaking or tilting.

[0038] Further, the ends of the middle layer of arc-shaped supporting rods 11 are provided with positioning holes 14, and the limiting sleeves 21 fitted on the middle layer of arc-shaped supporting rods 11 are threadedly connected with positioning bolts 27, and the positioning bolts 27 are connected with one of the positioning holes 14, so that the position of the movable frame assembly 1 on the fixed frame assembly 2 can be accurately locked.

[0039] Further, the tail end of the bottom layer of arc-shaped supporting rods 11 is connected with a moving roller 16, and the moving roller 16 is in the same plane as the bottom surface of the fixed frame assembly 2. When the device needs to be moved, the moving roller 16 can be used to reduce frictional resistance and make the operation more labor-saving. At the same time, because the roller is flush with the bottom surface, the moving roller 16 will not interfere with the stability in the auxiliary sitting state.

[0040] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the upper and lower limit sleeve 21 of the fixed frame assembly 2 is fixedly connected with a sleeve support rod 24 arranged vertically, the bottom layer limit sleeve 21 is respectively connected at both ends of the arc-shaped groove pipe 22, the sleeve support rod 24 can enhance the overall rigidity of the fixed frame assembly 2, by connecting the upper and lower limit sleeve 21, a stable frame structure is formed, effectively dispersing the dynamic load generated when the movable frame assembly 1 moves, preventing deformation or loosening of the assembly, the connection of the bottom layer limit sleeve 21 and the arc-shaped groove pipe 22 ensures that the base part of the fixed frame assembly 2 has sufficient supporting force, so that the device can maintain balance in various states, reducing the risk of tilting.

[0041] Further, the bottom end of the fixed frame assembly 2 is provided with a bottom surface support pipe 23, the bottom surface support pipe 23 and the arc-shaped groove pipe 22 are arranged in parallel, and a plurality of bottom support rods 25 are fixedly connected between the bottom surface support pipe 23 and the arc-shaped groove pipe 22, the bottom support rod 25 tightly combines the bottom surface support pipe 23 and the arc-shaped groove pipe 22 to form a solid base frame, effectively resisting external impact and wear caused by long-term use, not only improving the structural integrity of the device, but also reducing the shaking when moving, making the elderly feel safer when walking or sitting, it should be noted that the sleeve support rod 24, the bottom surface support pipe 23 and the bottom support rod 25 are all lightweight hollow thin-walled pipe structures, and the end of the bottom surface support pipe 23 is arc-shaped.

[0042] As shown in Figures 6 to 9 The inner side of the tail end support plate 13 is provided with an inner clamping groove 18, and the plate body part at the bottom end of the tail end support plate 13 is provided with a through groove 19, the bottom end of the first and second folding plates 31 and 32 is connected with a butt joint shaft 38, the bottom end of the first folding plate 31 is rotatably connected in the through groove 19 of one of the tail end support plates 13 through the butt joint shaft 38, the bottom end of the second folding plate 32 is rotatably connected in the through groove 19 of the other tail end support plate 13 through the butt joint shaft 38, and the first and second folding plates 31 and 32 are clamped in the inner clamping groove 18 when they are in the folding state, the inner clamping groove 18 is used to accommodate the first and second folding plates 31 and 32, and when the first and second folding plates 31 and 32 are folded out of the groove, the through groove 19 can limit the first and second folding plates 31 and 32, that is, the bottom end of the first and second folding plates 31 and 32 can be blocked, ensuring that the first and second folding plates 31 and 32 are in a horizontal state, thereby facilitating the elderly to sit on the folding plates, the hidden design makes the folding plate assembly 3 blend into the whole device when not in use, avoiding the risk of tripping or occupying additional space caused by the protruding part, and when the first and second folding plates 31 and 32 are folded out of the inner clamping groove 18, the through groove 19 limits them, ensuring that the bottom end is firmly blocked, so that the folding plates remain in a horizontal state, facilitating the elderly to sit safely.

[0043] Further, the side edge abutting parts of the first folding plate 31 and the movable abutting plate 33 are connected with a plurality of cross invisible hinges 34, and the connecting side of the cross invisible hinge 34 is close to the side of the second folding plate 32. The cross invisible hinge 34 can provide a hidden and reliable connection mode, so that the movable abutting plate 33 can be smoothly unfolded or folded, without affecting the overall appearance and function of the folding plate assembly 3. When the movable abutting plate 33 needs to be unfolded to be connected with the abutting groove 35 of the second folding plate 32, the cross invisible hinge 34 ensures the stability of the abutting process, prevents the misplacement or loosening of the plate, and thus forms a continuous cushion surface, improves the comfort of the old people, and reduces the risk of scratching or pinching.

[0044] Further, the upper plate surface of the movable abutting plate 33 in the unfolded state is provided with a plurality of V-shaped clamping grooves 36, and the groove bottom surface of the abutting groove 35 is provided with a plurality of V-shaped clamping strips 37. When the movable abutting plate 33 is in the unfolded state, the V-shaped clamping strips 37 are correspondingly clamped and connected with the V-shaped clamping grooves 36. The corresponding clamping of the V-shaped clamping strips 37 and the V-shaped clamping grooves 36 ensures that the connection between the movable abutting plate 33 and the second folding plate 32 is more firm. The interlocking mechanism of the V-shaped clamping grooves 36 and the V-shaped clamping strips 37 effectively prevents the two folding plates from sliding or separating when bearing.

[0045] Working principle: In the auxiliary moving state, the front ends of the two groups of movable frame assemblies 1 are abutted to form a stable support frame, and the old people can be located inside the frame, holding the arc-shaped supporting rod 11 or the front end supporting rod 17 of the movable frame assembly 1 with both hands, and walking with the help of the support force provided by the device to reduce the risk of falling;

[0046] When it is needed to switch to the auxiliary sitting state, the user pushes the movable frame assembly 1 to make the tail ends thereof abut together. At this time, the position of the movable frame assembly 1 is locked by the positioning bolt 27 and the positioning hole 14 of the middle layer arc-shaped supporting rod 11, to prevent accidental sliding.

[0047] Then, the folding plate assembly 3 is unfolded, the first folding plate 31 and the second folding plate 32 are flipped out from the inner clamping groove 18 of the tail end supporting plate 13, and are rotated in the through groove 19 through the abutting shaft 38. The through groove 19 forms a limit to ensure that the first folding plate 31 and the second folding plate 32 are in a horizontal state. The movable abutting plate 33 is unfolded through the cross invisible hinge 34 and clamped into the abutting groove 35 of the second folding plate 32. The V-shaped clamping strips 37 are correspondingly clamped and connected with the V-shaped clamping grooves 36, to form a continuous cushion surface. The old people can directly sit down and rest without turning around or moving the whole device.

[0048] During the whole process, the bottom surface support pipe 23 of the fixed frame assembly 2 is connected with the arc-shaped slot pipe 22 through the bottom support rod 25 to provide stable base support and reduce shaking, while the layered arc-shaped supporting rod 11 of the movable frame assembly 1 is ensured to be uniformly stressed when bearing load through the front end support rod 17, the tail end support plate 13 and the tail end support rod 15, thereby avoiding local stress concentration; the lightweight design such as the arc-shaped supporting rod 11, the limiting sleeve pipe 21 and the arc-shaped slot pipe 22 adopts a hollow thin-walled tubular structure, and the first folding plate 31, the second folding plate 32 and the movable butt joint plate 33 are in a honeycomb hollow plate structure, the end head and the corner of each component are treated with a circular arc, the overall weight is reduced, the old people or nursing personnel can easily operate, and the structural strength and safety are maintained.
