Problems solved by technology

The stair lift needs to be installed with a series of supporting facilities before it can be used, so the cost is relatively high. At the same time, because the stair lift is relatively large, it will occupy most of the stair space after installation, which will affect other people's use of the stairs
Electric stair-climbing wheelchairs are only suitable for elderly people who use wheelchairs, and most elderly people do not need to use wheelchairs, so electric stair-climbing wheelchairs are not universally applicable
Another way is to install elevators, but the cost is huge and the maintenance is complicated. In some communities, especially old communities where the elderly live, it is difficult to ensure that every family can enjoy the convenience of elevators.
[0004] For most elderly people, they actually have the basic ability to go up and down stairs alone. However, due to age, physical decline, and possible arthritis that affects the ability to go up and down stairs, it takes a lot of time for the elderly to go up and down stairs. It takes longer time and more physical strength, which is not conducive to the life of the elderly, especially when the elderly live alone, they often encounter the situation of carrying heavy objects upstairs, which deepens the inconvenience of the life of the elderly
[0005] Among the existing technical solutions, the application publication number is CN 111809809 A, which is a handrail-based stair climbing auxiliary device. The bayonet of the pull rod is used to snap into the handrail of the stairs. Stretch out, the device relies on the cooperation with the handrail of the stair railing to achieve the power-assisted effect, but this device cannot carry heavy objects, and the user needs to push the pull rod to move a step every time he goes up a step. The operation steps are cumbersome, inconvenient to use, and not in line with human nature The design concept is relatively complex, and the boosting effect is not obvious

Embodiment 1

[0081] Under normal environmental conditions, the processor of the induction controller uses a low-cost STM32F103C8T6 single-chip microcomputer, and the usage scenario is the process of going up stairs:

[0082] The user first hangs the weight on the hook 18, then holds the handrail 6 with both hands and pushes it upwards. The handrail 6 is subjected to an upward thrust along the stairs, and the handrail 6 bends upwards under the action of the thrust at this time. This bending deformation causes the distance between the two differential capacitance plates of the acceleration sensor in the induction module 17 to become smaller, and the change data is transmitted to the induction controller through the wireless module, and then controls the servo motor 1 to rotate forward. Now the transmission mechanism starts to work, and the armrest 6 moves upwards under the drive of the servo motor 1 . At the same time, the resistance value of the stress sensor in the induction module 17 chan...

Embodiment 2

[0084] In a more extreme environment (such as -20°C), the processor of the induction controller adopts the S7-1200 industrial PLC that can be used in a relatively harsh environment. The usage scenario is the process of going up stairs:

[0085] The user first hangs the weight on the hook 18, then holds the handrail 6 with both hands and pushes it upwards. The handrail 6 is subjected to an upward thrust along the stairs, and the handrail 6 bends upwards under the action of the thrust at this time. This bending deformation causes the distance between the two differential capacitance plates of the acceleration sensor in the induction module 17 to become smaller, and the change data is transmitted to the induction controller through the wireless module, and then controls the servo motor 1 to rotate forward. Now the transmission mechanism starts to work, and the armrest 6 moves upwards under the drive of the servo motor 1 . At the same time, the resistance value of the stress senso...

Embodiment 3

[0087] Under normal environmental conditions, the processor of the alarm controller adopts STM32F407ZGT6 single-chip microcomputer and ESP8266 Internet of Things module. The usage scenario is when the user feels unwell during use:

[0088] The user holds the handrail 6 with both hands, and when climbing up the stairs, when he suddenly feels unwell, he can press the one-key alarm button 16 on the handrail 6, and after the processor of the alarm controller receives the one-key alarm signal, it will pass The ESP8266 IoT module sends the stair position and floor position of the elderly to the management room, and connects the voice to communicate with the elderly to help the elderly out of danger.

Abstract

The invention discloses a stair climbing power assisting device and a stair climbing power assisting method. The method includes the steps that a transmission mechanism comprises two groups of servo motors, worms, transmission shafts, worm wheels and chain wheels, the two groups of servo motors, the worms, the transmission shafts, the worm wheels and the chain wheels are oppositely arranged on the left side and the right side of a base, the worms are connected with output shafts of the servo motors, the worm wheels are matched with the worms to form meshing transmission, and the transmission mechanism further comprises chains meshed with the chain wheels on the two sides to form chain transmission; the transmission mechanism further comprises a sliding rail, a sliding platform and a chain transmission device, the upper side of the chain transmission device is provided with strip-shaped teeth matched with the upper side of the chain, and the lower side of the chain transmission device is provided with a small chain wheel matched with the lower side of the chain; and the transmission mechanism further comprises a folding rod, a handrail and an induction module mounted on the handrail, the induction module comprises a stress sensor, an acceleration sensor and a wireless module, the wireless module is connected with an induction controller, and the signal output end of the induction controller is connected with a driver of the servo motor. According to the stair climbing power assisting method, the walking aid can help the old to go upstairs and downstairs easily and carry heavy objects, and is humanized in design, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of life assistance, and in particular relates to a stair climbing booster device and a booster method. Background technique [0002] Population aging is an important trend of social development, a manifestation of the progress of human civilization, and also the basic national conditions of our country for a long time to come. Since my country entered an aging society at the end of the 20th century, the number of elderly people and their proportion to the total population have continued to grow. From 2000 to 2019, the number of elderly people aged 65 and over in my country increased by nearly 62.96 million. In the future, the degree of aging will continue to deepen. Facing the gradual deepening of population aging, my country will gradually improve the old-age security system for the elderly to fully protect the life of the elderly in their later years. [0003] Due to their age, the elderly have many incon...
