[0056] The present invention has at least the following beneficial technical effects:
[0057] 1. The user-adaptive multifunctional walking aid provided by the present invention adopts a modular design, which divides the walking aid into three modules: a shock-absorbing chassis module, a height adjustment module, and a user-adaptive module, making it easy to assemble the walking aid as a whole.
[0058] 2. The user-adaptive multifunctional walking aid provided by this invention adopts a parallelogram mechanism and a single-sided scissor mechanism in its height adjustment module, which enables personalized height adjustment during the height adjustment process and significantly improves the smoothness of the adjustment process; at the same time, it enables the walking aid to have a certain folding capability, and the height of the walking aid can be adjusted to about one-third of the usable height, thus improving the portability of the walking aid.
[0059] 3. The user-adaptive multi-functional walking aid provided by this invention has an added suspension module to the shock-absorbing chassis module, which reduces the manufacturing difficulty of the walking aid and improves the grip performance of the brushless hub motor and omnidirectional wheels; at the same time, the shock-absorbing damping spring improves the walking aid's obstacle-crossing ability in rough environments and enhances the stability of the walking aid when driving.
[0060] 4. The user-adaptive multifunctional walking aid provided by this invention has a variety of usage methods. It is equipped with multiple handrails at the front and rear, and has suspension hooks for chest fixation and waist fixation.

[0061] 5. The user-adaptive multifunctional walking aid provided by this invention is equipped with a user-adaptive module. After the user adjusts the waist suspension height, the gyroscope sensor on the telescopic link detects the angle change and controls the motor to adjust the height of the walking aid. When the angle of the telescopic link returns to horizontal, the spring buckle locks itself, and the walking aid is adjusted to a suitable height. The user does not need to adjust the height of the walking aid, reducing the requirements of the walking aid on the user's own ability.

[0077] The preferred embodiments of the present invention are described below to make the technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.
[0078] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and the present invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components is appropriately exaggerated in the drawings.
[0079] This invention provides a user-adaptive multifunctional walking aid. The height adjustment module consists of a push rod motor and a support mechanism. The motor drives the support mechanism to achieve personalized height adjustment, making the height adjustment of the walking aid convenient. It can be used independently by users with walking disabilities, improving the user's independent walking ability. The support mechanism combines a single-sided scissor mechanism and a parallelogram mechanism to realize the folding function of the walking aid.
[0080] like Figure 1 As shown, the user-adaptive multifunctional walking aid of this embodiment includes a shock-absorbing chassis module 3, a height adjustment module 2, and a user-adaptive module 1. The shock-absorbing chassis module 3 is located at the bottom of the walking aid and can move to buffer vibrations during walking. The height adjustment module 2 is located on the upper part of the shock-absorbing chassis module 1 and can adjust the height. The user-adaptive module 1 is located on the upper part of the height adjustment module 2 and can adapt to the user's waist height.
[0081] like Figure 2As shown, the shock-absorbing chassis module 3 includes a chassis connector 4 and support mechanisms on both sides of the chassis connector. The two support mechanisms have identical structures and are arranged in parallel, with their head and tail ends aligned. The two ends of the chassis connector 4 are connected to the two support mechanisms respectively. The support mechanisms include shock absorber connector 1 5, shock absorber damper 6, brushless hub motor connector 7, brushless hub motor 8, chassis 9, shock absorber connector 2 10, caster wheel connector 11, and caster wheel 12. The front end of the chassis 9 is bolted to shock absorber connector 1 5, and the rear end is bolted to shock absorber connector 2 10. The two ends of the chassis connector 4 are bolted to the two shock absorber connectors 1 5. The brushless hub motor connector 7 is hinged to the front end of the chassis 9 with bolts; the caster wheel connector 11 is hinged to the rear end of the chassis 9 with bolts; the brushless hub motor 8 is bolted to the brushless hub motor connector 7; and the caster wheel 12 is bolted to the caster wheel connector 11. Two shock absorbers 6 are provided. The first shock absorber 6 is bolted to the shock absorber connector 5 and the brushless wheel hub motor connector 7 at both ends, forming the front shock absorption mechanism. The second shock absorber 6 is bolted to the shock absorber connector 10 and the universal wheel connector 11 at both ends, forming the rear shock absorption mechanism. The shock absorber 6 can extend and shorten to a certain extent, absorbing a certain amount of potential energy and playing a shock absorption role. At this time, the brushless wheel hub motor connector 7 and the universal wheel connector 11 can rotate around the bolts at a certain angle, realizing the suspension function, improving the grip of the front and rear wheels of the walking aid, thereby improving the stability of the walking aid in outdoor environments. The rear-mounted brushless wheel hub motor 8 and the front-mounted universal wheel 12 can realize multiple functions such as downhill speed control, uphill assistance, and hill-climbing, reducing the physical exertion of using the walking aid and improving the safety of the walking aid when traveling on slopes.
[0082] like Figure 1 , Figure 3 and Figure 13As shown, the height adjustment module 2 has two sets, which are connected to the support structures on both sides respectively. The height adjustment module 2 includes an internal connecting rod 13, an adaptive module connector 14, a support connecting rod 15, a push rod motor 16, a support connecting rod connector 17, an internal connecting rod 28, a support connecting rod 29, a fixed base 20, and a push rod motor 28. The support connecting rod 15, the support connecting rod 20, the internal connecting rod 13, and the internal connecting rod 29 all have through holes at their front and rear ends. The adaptive module connector 14 has through holes on both the upper and lower sides. The rear end of the support connecting rod 15 is hinged to the upper through hole 141 by bolts, and the rear end of the internal connecting rod 13 is hinged to the lower through hole 141 by bolts. Hole 142 is hinged; the front end of support link 15 is hinged to the through hole structure 172 on the support link connector 17 by bolts, and the front end of internal link 13 is hinged to the lower through hole 174 by bolts; the front end of support link 29 is hinged to the through hole structure 177 on the support link connector 17 by bolts, and the front end of internal link 28 is hinged to the lower through hole 176 by bolts; the fixed base 20 has two through holes, upper and lower, the front end of support link 29 is hinged to the lower through hole 202 by bolts, and the front end of internal link 13 is hinged to the upper through hole 201 by bolts. The two ends of push rod motor 16 are hinged to support link 15 and support link 29 respectively, and the two ends of push rod motor 46 are hinged to support link 29 and base frame 9 respectively.
[0083] like Figure 4 The diagram shows the structure of the adaptive module connector 14, which includes a hollow round rod and a support member that is perpendicularly connected to the hollow round rod. The support member has through holes 141 and 142 for mounting the hinge.
[0084] like Figure 5 The diagram shows the structure of the support rod connector 17. The cross-section of the support rod connector 17 is arc-shaped at both ends, and a groove 171 is opened on one side. The groove 171 is used to accommodate the connecting mechanism. Several through holes are opened on the side wall of the groove 171.
[0085] like Figure 6 The diagram shows the structure of the fixed base 20, which includes a hollow square column and a cylinder connected to the side of the hollow square column. The cylinder has through holes 201 and 202 for mounting hinge components.
[0086] The line connecting the centers of the paired through holes on the adaptive module connector 14, the support rod connector 17, and the fixed base 20 has the same angle with the horizontal line and is 60°. This angle is calculated to be the optimal angle. When the walker is fully folded, the support rod 15 interferes with the internal rod 13, and the support rod 29 interferes with the internal rod 28, which serves as a limiting function.
[0087] like Figure 7As shown, the hinge points between the fixed base 20, the second support rod 19, the second internal link 18, and the support link connector 17 form a parallelogram mechanism; the hinge points between the adaptive module connector 14, the first support rod 15, the first internal link 13, and the support link connector 17 also form a parallelogram mechanism; the parallelogram mechanism ensures that during height adjustment or folding of the walker, the walker armrest, which is one side of the parallelogram mechanism, always remains parallel to the ground, which is the other side of the parallelogram mechanism, ensuring that the user does not need to release the walker during height adjustment. The scissor mechanism of the height adjustment module 2 has good folding performance and can be locked at any height. Simplifying it into a single-sided mechanism can reduce the overall weight of the walker without affecting its good folding performance and support capacity. The combination of the parallelogram mechanism and the single-sided scissor mechanism, replacing the two support arms of the scissor mechanism with the parallelogram mechanism as the support mechanism of the walker, gives this mechanism the characteristics of both the parallelogram mechanism and the scissor mechanism.
[0088] like Figure 8 The diagram shows the connection mechanism in the height adjustment module 2. The connection mechanism is located on the support rod connector 17 and specifically includes a gear 21, a disc damper 22, a shaft 23, a bearing 24, and a hexagonal nut 25. The bearing 24 is installed inside the through hole of the support rod connector 17, and the disc damper 22 is mounted on the bearing 24. The disc damper 22 is symmetrically arranged in the groove 171 of the support rod connector 17. The shaft 23 passes through the through hole 174, and the other end of the shaft 23 is limited by the hexagonal nut 25. The gear 21 is installed on the opposite side of the disc damper 22 and is fixed to the shaft 23 by a flat key. The upper and lower gears 21 mesh with each other. Keyways are provided inside the internal connecting rod 13 and internal connecting rod 29, and they are fixed to the shaft 23 by flat keys. The above connecting mechanisms are symmetrically arranged on both sides of the support link connector 17. When the angle of the lower link mechanism changes, the internal link drives the shaft 23, and the shaft 23 drives the gear 21 to change angle, so that the upper and lower links produce the same angle change. The disc damper 22 generates a damping torque in the clockwise direction and does not generate a damping torque in the counterclockwise direction. It can effectively protect the rotating mechanism, reduce the noise and inertia of the walker during the height adjustment process, and significantly improve the stability and service life of the mechanism.
[0089] like Figure 9 and Figure 10As shown, the user adaptive module 1 includes armrest glove 1 26, multi-functional bracket 27, chest fixation 28, suspension hook 1 29, armrest glove 2 30, quick-release buckle 31, suspension hook 2 32, waist fixation 33, ball joint seat 34, ball joint 35, ball joint connector 36, telescopic inner rod 37, eccentric self-locking buckle 38, gyroscope sensor 39, and telescopic outer rod 40. Armrest glove 1 26 and armrest glove 2 30 are fixed to the multi-functional bracket 27 by bolts. The chest fixation 28 is fixed to the multi-functional bracket 27 by four quick-release buckles 31, and the height of the chest fixation 28 can be adjusted by the quick-release buckles 31. Both the chest fixation 28 and the waist fixation 33 are equipped with double-layer hook rails. Suspension hook 1 29 is installed on the guide rail of the chest fixation 28, and suspension hook 2 32 is installed on the guide rail of the waist fixation 33. The ball joint seat 34 is bolted to the waist fixation 33, and the ball joint 35 is installed inside the ball joint seat 34. The ball joint connector 36 is bolted to the ball joint 35 and bolted to the through hole at the front end of the telescopic inner rod 37. The telescopic inner rod 37 is nested inside the telescopic outer rod 40, and its length is adjusted or locked by the eccentric self-locking buckle 38. The gyroscope sensor 39 is bolted to the telescopic outer rod 40 and is used to detect changes in the angle between the telescopic linkage mechanism and the horizontal direction. When the height of the walker is adjusted to the point where the telescopic linkage mechanism is kept horizontal, the push rod motor 16 and the push rod motor 2 46 are stopped, realizing the user self-adaptation function. The chest fixation 28 and the waist fixation 33 are equipped with strap hooks, and the user can fix himself to the walker with the straps. In the event of a fall, the straps will lift the body and prevent the body from directly contacting the ground, thus realizing the fall prevention function. The multi-functional bracket 27 has two handles on the front, which the user can hold to push the walker forward. There is a horizontal handle on the rear, which is higher than the front handle, and the user can hold this handle and lie on the walker to move backward. The bottom of the multi-functional bracket 27 has two cylinders, which are connected to the adaptive module connector 14 in a nested manner.
[0090] like Figure 11 and Figure 12 As shown, the user adaptive module 1 also includes an angle adjustment mechanism, which specifically includes an angle adjustment link 1 41, an angle adjustment shaft 42, an angle adjustment link 2 43, a spring lock 44, and a link connector 45. The angle adjustment link 1 41 is hinged to the telescopic outer rod 40 by bolts, and the rear end of the angle adjustment link 2 43 is hinged to the lower end through hole of the angle adjustment link 1 41 by the angle adjustment shaft 42. The front end of the angle adjustment link 2 43 has a through hole 431, which is hinged to the lower end through hole of the link connector 45 by bolts. The telescopic outer rod 40 is hinged to the upper end through hole of the link connector 45 by bolts. When the telescopic outer rod 40 is adjusted to a horizontal state, the spring lock 44 self-locks, and the angle adjustment mechanism cannot be adjusted at this time. After the spring lock 44 is unlocked, the angle can be adjusted.
[0091] In this embodiment of the user-adaptive multi-functional walking aid, when the walking aid is in its initial state, the height of the waist fixation 33 is different from the user's waist height. The user needs to manually open the spring lock 44 to adjust the height of the waist fixation 33. At this time, the angle of the telescopic outer rod 40 will change. After the gyroscope sensor 39 detects the angle change, it controls the height adjustment module push rod motor 16 and push rod motor 2 46 to adjust the overall height of the walking aid. When the telescopic outer rod 40 returns to the horizontal state, it is considered that the height of the walking aid is most suitable for the user. At this time, the spring lock 44 locks itself, and the angle of the telescopic outer rod 40 no longer changes. During the use of the walking aid, it can realize the function of supporting the user's waist.
[0092] When using the walking aid in this embodiment, such as Figure 13 The image shows the walker in its fully folded state. When push rod motor 16 and push rod motor 26 are at their lowest travel positions, the walker height adjustment module 2 is fully retracted, and the walker height is adjusted to its lowest point. The angle between support rod 15, support rod 2 19, and the horizontal direction is at its minimum, which is 7°. Figure 14 The diagram shows the highest position of the walker. When push rod motor 16 and push rod motor 26 are at their highest stroke positions, the walker height adjustment module 2 is fully extended. The walker height is adjusted to its highest position, and the angle between support rod 15 and support rod 29 and the horizontal direction is at its maximum, which is 35°. The push rod motors can be locked within their maximum stroke range, and the walker height can be adjusted arbitrarily between the fully folded height and the maximum height. The angle between the two support arms of the scissor mechanism and the horizontal direction is controlled by push rod motor 16 and push rod motor 246, thereby controlling the height of the walker's handrails. The user does not need to adjust it manually.
[0093] This invention applies a scissor mechanism to the support structure of a walking aid, abandoning the traditional frame structure. This allows the walking aid to freely adjust its height and fold, while reducing its weight and size. The invention provides multiple human-computer interaction methods. Handrails are installed on both the front and rear sides of the module, allowing users to turn freely within the walking aid and choose different usage modes. The module has an overall frame structure, equipped with a chest support module and a lumbar support module, which secures the user with straps. Based on a parallelogram mechanism, this invention designs a telescopic link that can freely adjust its height. This link connects the walking aid body module and the multi-functional human-computer interaction module. The push rod is equipped with a gyroscope that can detect its tilt angle and automatically adjust the walking aid height, achieving user self-adaptation.
[0094] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
