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...
