Crutch with controllable rod length through pressure sensing and method thereof for controlling rod length

Abstract

The invention relates to a crutch with a controllable rod length through pressure sensing and a method thereof for controlling the rod length. The crutch comprises a holding part, a leading screw, a rod body, a control module and a supporting part, wherein the holding part and the supporting part are configured with a plurality of pressure sensing units to sense the held strength applied to the holding part and the contacting strength applied to the ground by the supporting part so as to generate a plurality of holding pressure values and feedback pressure values; the rod body is connected with the holding part; a motor is configured on the supporting part; one end of the leading screw is meshed with the motor, and the other end is pivotally connected with the rod body; the holding part judges that the holding part is held according to the holding pressure values and the feedback pressure values, and when the crutch is tilted, the motor is ordered to rotate to drive the leading screw to pivotally rotate so that the leading screw and the rod body translate in opposite directions to shorten the crutch or lengthen the crutch. The invention also provides the method for controlling therod length through the pressure sensing. Thus the crutch can be regulated to a height suitable for a user by matching with slope variation.

Description

technical field [0001] The invention relates to a crutch with the function of length adjustment and its length adjusting method, in particular to a crutch and its length adjusting method for adjusting its own length according to the inclination angle of the crutch and the pressure of the crutch contacting the ground. Background technique [0002] see Figure 1A , Figure 1B as shown, Figure 1A is a schematic diagram of a single-leg telescoping crutch of the prior art, Figure 1B is a schematic diagram of a prior art multi-leg telescoping crutch. In the prior art, crutches are sharp tools for assisting people with disabilities to walk. Early crutches were mostly single-legged crutches 1. However, in order to make the single-legged crutches 1 convenient for users to store and carry, the manufacturer developed a multi-segment single-legged crutches 1, which consists of columns 11 with different apertures connected in series, and has The ability of stretching to adjust the l...

Problems solved by technology

However, the single-legged crutch 1 only touches the ground with a single foot 12, and the user needs to spend a lot of effort to maintain the upright operation of the single-legged crutch 1, which makes it more inconvenient for the user to apply force. Therefore, some manufacturers have developed such Figure 1B The illustrated multi-leg telescopic crutch 2 uses a chassis 22 to configure multiple legs to assist the crutch to stand upright on the ground

But it still has inconvenience, that is, in order to facilitate the design and save costs, each branch 21 of the multi-legged telescopic crutch 2 has been designed in a standardized manner, so the length of each branch 21 is fixed, resulting in multi-legged telescopic crutches. The length adjustment mode of the crutches 2 is fixed, so it may not be possible to adjust the height that the user is comfortable with. It is easy to cause the multi-legged telescopic crutches 2 to be either too high or too low for the user after the length is adjusted.

In addition, when the user walks on a path with a gradient change, the user exerts force on the multi-legged telescopic crutch 2 in different ways. It is easy to form when the multi-legged telescopic crutch 2 is too long when going uphill. Telescopic crutch 2 is too short

As far as the user is concerned, once the slope changes, the length of the crutch needs to be adjusted, which is quite inconvenient to use

[0003] It can be seen that the above-mentioned existing crutches with length adjustment function and their length adjustment methods obviously still have inconvenience and defects in product structure, method and use. and need to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
