Technical Field
[0001] The utility model relates to the technical field of pedestrian assistance, in particular to a simple pedestrian assistor for large-inclination roadways. Background Art
[0002] A simple pedestrian assistor for large-inclination roadways is a mobile device designed to provide support and stability for pedestrians in inclined terrains or large-inclination roadways. This assistor usually has a special design to cope with steep inclinations and uneven terrains, helping pedestrians cross such environments safely. Its main functions are to provide stable support, convenient movement, and easy operation, so that pedestrians can walk or stand on steep inclined road surfaces. The assistor may be equipped with components such as handrails, support footrests, wheels, and braking systems to ensure that pedestrians can maintain balance and safety during use. This assistor is usually used in roadways or roads with inclined terrains such as mountains, slopes, and ramps to provide convenient and safe mobile support for pedestrians.
[0003] A simple pedestrian assistor for large-inclination roadways usually consists of multiple mechanisms such as a main frame, a handle / handrail, a support footrest, a wheel axle and wheels, a braking system, adjustable components, a folding structure, and additional functional components. The main frame is its skeleton, supporting the installation and operation of other components, while the handle / handrail is for pedestrians to hold or support to maintain balance and stability. The support footrest is located at the bottom, providing additional support and stability, especially on inclined ground. The wheel axle and wheels are used for movement and may be specially optimized for inclined terrains. The braking system is particularly important on steep slopes, controlling the stop and movement of the assistor. The adjustable components allow adaptation to different heights and terrains, and the folding structure facilitates carrying and storage. Additional functional components such as lights, alarms, seats, etc. provide more convenience and safety.
[0004] However, for a simple pedestrian assistor for large-inclination roadways, it is usually driven by the following devices. Although the manual pushing method is simple and reliable, it may increase the physical exertion of pedestrians and may not be practical enough for people with limited mobility. The electric drive method depends on power supply and is relatively heavy, increasing the difficulty of carrying and operation. At the same time, the maintenance cost is also high. Although the hydraulic drive system has high power and control performance, the maintenance cost is expensive and the structure is complex. Once a failure occurs, professional knowledge and skills may be required for repair. Therefore, a simple pedestrian assistor for large-inclination roadways is proposed to solve the above problems.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0032] Referring to Figure 1 and Figure 2 An embodiment provided by the present utility model: A simple walking aid for pedestrians in a large-inclination roadway, including a wall 1. An empty slot 21 is opened inside the wall 1. A bottom plate 2 is fixedly connected to the side wall of the wall 1. A motor 5 is fixedly connected to the top of the bottom plate 2. The output end of the motor 5 is fixedly connected to a first sprocket 6. The outer wall of the first sprocket 6 is rotatably connected to a first chain 7. The inner wall of the first chain 7 is rotatably connected to a second sprocket 8. The side wall of the second sprocket 8 is rotatably connected to a third sprocket 9. The outer wall of the third sprocket 9 is rotatably connected to a second chain 10. The inner wall of the second chain 10 is rotatably connected to a fourth sprocket 11. The outer wall of the fourth sprocket 11 is rotatably connected inside the empty slot 21. A support assembly is arranged inside the bottom plate 2. The support assembly includes a first fixing column 3, and the outer wall of the first fixing column 3 is fixedly connected inside the bottom plate 2.
[0033] Specifically, when using the simple walking aid for pedestrians in a large-inclination roadway, first, the output end of the motor 5 drives the first sprocket 6 to rotate, thereby starting the operation of the entire chain drive system. The rotation of the first sprocket 6 drives the rotation of the first chain 7, causing the second sprocket 8 inside the structure to start rotating. The movement of the second sprocket 8 drives the third sprocket 9 on the side wall to rotate together, and then transmits the power to the second chain 10 on the outer wall. The rotation of the third sprocket 9 also synchronously drives the second chain 10 on the outer wall to rotate. At the same time, the movement of the second chain 10 drives the fourth sprocket 11 on the inner wall to rotate again, realizing the transmission and conversion of power, enabling the walking aid to effectively assist pedestrians in walking in a large-inclination roadway and improving the stability and safety of walking.
[0034] Referring to Figure 4 A connecting block 4 is fixedly connected to the outer wall of the second chain 10. A second clamping column 18 is fixedly connected to the side wall of the connecting block 4. A first clamping column 15 is slidably connected inside the second clamping column 18. A clamping groove 19 is opened on the outer wall of the first clamping column 15. A ball 16 is arranged on the outer wall of the clamping groove 19. A spring 20 is arranged on the outer wall of the second clamping column 18. A collar 17 is slidably connected to the outer wall of the spring 20. A second fixing column 14 is fixedly connected inside the first clamping column 15. One end of the second fixing column 14 is fixedly connected to a handrail 13.
[0035] Specifically, a second clamping post 18 is installed on the outer wall of the first clamping post 15. This design allows for easy operation when the handrail 13 needs to be replaced. At the same time, by pulling the collar 17, the internal spring 20 will be contracted, and the movement of the collar 17 will drive the rolling balls 16 on the inner wall to slide. The movement of the rolling balls 16 then drives the inner wall of the clamping groove 19 opened on the outer wall of the first clamping post 15. Such a structural design allows for the convenient replacement of the handrail 13 without complex disassembly or repair. It effectively improves the maintenance and usability of the walking aid, providing a better user experience for users.
[0036] Refer to Figure 1 and Figure 3 , a light bulb 12 is fixedly connected to the bottom of the handrail 13.
[0037] Specifically, one end of the second fixing post 14 is installed with a handrail 13, providing additional support and stability for pedestrians. At the same time, a light bulb 12 is fixed to the bottom of the handrail 13, realizing the lighting function during walking. This design not only increases the practicality of the walking aid but also improves the safety and convenience of pedestrians when walking in large-inclination roadways.
[0038] Working principle: When using the simple walking aid for pedestrians in a large-inclination roadway, first, the output end of the motor 5 drives the first sprocket 6 to rotate. The rotation of the first sprocket 6 drives the first chain 7 to rotate. The rotation of the first chain 7 drives the second sprocket 8 on the inner wall to rotate. At the same time, the rotation of the second sprocket 8 drives the third sprocket 9 on the side wall to rotate together. The rotation of the third sprocket 9 drives the second chain 10 on the outer wall to rotate together. At the same time, the rotation of the second chain 10 drives the fourth sprocket 11 on the inner wall to rotate, achieving the effect of using the chain as the driving end. Subsequently, a connecting block 4 is fixed to the outer wall of the second chain 10. At the same time, the rotation of the second chain 10 drives the connecting block 4 to move. The movement of the connecting block 4 drives the first clamping post 15 to move together. A second fixing post 14 is fixed inside the first clamping post 15. At the same time, one end of the second fixing post 14 is fixed with a handrail 13. At the same time, a light bulb 12 is fixed to the bottom of the handrail 13, achieving the lighting effect. The second clamping post 18 slides on the outer wall of the first clamping post 15. At the same time, pulling the collar 17 drives the internal spring 20 to contract. At the same time, the movement of the collar 17 drives the rolling balls 16 on the inner wall to slide. And the movement of the rolling balls 16 drives the inner wall of the clamping groove 19 opened on the outer wall of the first clamping post 15, achieving the effect of being able to replace the handrail 13.
