Embodiment 1

[0067] see figure 1 , the present embodiment provides an automatic retractable smart crutch. The smart crutch can be used by people with mobility impairments such as the elderly, and can also be used by people with visual impairments. The intelligent crutches are generally made of lighter and harder materials, such as aluminum alloy, when they are manufactured. In this embodiment, the smart crutch includes a crutch head 1 , an upper rod 7 , a lower rod 12 and an obstacle avoidance vehicle 17 . In this embodiment, the crutch additionally includes a stopper 11 .

[0068] see figure 2 The crutch head 1 is provided with a pressing installation hole 2, the crutch head 1 can adopt the existing crutch head, which is generally T-shaped, and the surface can be provided with structures such as threads, so that the person holding the cane can hold it. Under normal circumstances, due to the special shape of the crutch head 1, the relative position of the person with the cane and the c...

Embodiment 2

[0086] see Figure 16 , this embodiment provides an automatic retractable intelligent crutch, which adds some structures on the basis of embodiment 1. Wherein, the obstacle avoidance vehicle 17 also includes an alarm module 25 and at least one camera 24 . The camera 24 is installed on the casing 19, and is used for taking dynamic images outside the casing 19. When the ultrasonic sensor 22 detects an obstacle, the control board 23 is also used to first obtain the outline of the obstacle in the dynamic image according to the dynamic image, and then compare the outline of the obstacle with a preset outline of a human body falling to the ground, and obtain the similarity, Finally, it is judged whether the similarity is greater than a preset similarity, and when the similarity is greater than the preset similarity, the alarm module is driven to send a fall alarm message. In this way, when it is judged that the similarity reaches the preset similarity degree, it means that the obs...

Embodiment 3

[0088] This embodiment provides an automatic retractable intelligent crutch, which adds a push switch on the basis of Embodiment 1. The push switch is installed in the press mounting hole 2, and the push end protrudes from the outer surface of the crutch head 1; the push switch is used to open or close the power supply system of the obstacle avoidance vehicle 17, and the power supply system is used to supply the servo motor 21, the ultrasonic sensor 22 and The control board 23 supplies power. Since the power supply system of the obstacle avoidance car can be controlled by pressing the switch, the person with a cane can turn off the function by pressing the switch without the need for the obstacle avoidance function provided by the crutches, thereby saving more electric energy, and can also be turned off in time when the crutches falsely alarm The obstacle avoidance function of crutches makes it more convenient to use crutches.

Abstract

The invention discloses an automatic telescopic intelligent walking stick and an intelligent obstacle avoidance method thereof. The walking stick comprises a walking stick head, an upper rod, a lowerrod and an obstacle avoidance vehicle. The top end of the upper rod is connected with the walking stick head, and a plurality of protruding blocks are arranged on the outer wall at equal intervals. Aslideway which extends to the top end of the lower rod and is matched with the upper rod is formed in the lower rod, and a plurality of grooves are formed in the inner wall of the slideway. When the bottom end of the upper rod is inserted into the top end of the lower rod, the protruding blocks are limited in the corresponding grooves. The obstacle avoidance vehicle comprises a case, at least three servo motors, at least three Mecanum wheels, at least three ultrasonic sensors and a control panel. The control panel judges the relative position I of the crutch person and the case, judges the relative position II of the obstacle and the case, calculates a deviation angle, judges whether the deviation angle is larger than a preset angle or not, and drives the case to rotate until the deviationangle is larger than the preset angle if not. The obstacle avoidance walking stick meets the use requirements of walking stick persons with different heights, achieves the obstacle avoidance function, and guarantees the walking safety of the walking stick persons.

Description

technical field [0001] The present invention relates to an intelligent crutch in the technical field of crutches, in particular to an automatically retractable intelligent crutch, and also relates to an intelligent obstacle avoidance method for the automatic extendable intelligent crutch of the crutch. Background technique [0002] A cane is a walking aid, usually a wooden or metal stick. There are various types and materials of crutches, among which bamboo and wooden crutches are the most. Crutches, especially armpit crutches, are important medical rehabilitation aids, which can provide support for the elderly and patients with limited mobility, and enable people on crutches to walk on their own, and are widely used. [0003] Now with the prosperity of science and technology, more and more smart devices are circulating on the market. Crutches were originally just a simple and common walking aid. With the rise of the Internet of Things, there are now many types of function...
