the electric quantity prompting lamp is electrically connected with the processor.

Furthermore, a capacitive touch key is arranged on the crutch handle; the capacitive touch key is electrically connected with the processor.

By adopting the technical scheme, the utility model has the beneficial effects that: this walking stick of intelligent regulation length judges whether the people is moving through setting up acceleration sensor, if the people is moving to atmospheric pressure altitude sensor detects the elevation/decline of height above sea level, then the treater intelligence judges that the people is in the topography of climbing or downhill slope. If the user is in a climbing state, the processor controls the linear push rod to contract, the crutch body is shortened, and the climbing of the user is facilitated; if the user is in the downhill state, the processor controls the linear push rod to extend, the crutch body is lengthened, and the user can conveniently go downhill.

Furthermore, the linear push rod can be manually operated to extend or retract through a telescopic operation key.

Furthermore, a capacitive touch key is further arranged on the handle of the crutch, when a user uses the crutch, the user can touch the capacitive touch key by hand, the processor judges that the user is using the crutch, the acceleration sensor and the air pressure height sensor work, and the processor intelligently controls the electric push rod to extend or shorten according to signals transmitted by the acceleration sensor and the air pressure height sensor.

If the capacitive touch key does not detect the touch of a human hand, the acceleration sensor and the air pressure height sensor do not work, and the electric push rod cannot extend or shorten.

Detailed Description

The utility model will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1, 2, 3 and 4, the present embodiment provides a crutch with an intelligent length adjustment, which includes a crutch handle 1 and a crutch body 2 connected to the crutch handle 1. A handle mounting groove 100 is formed in the crutch handle 1, and a processor 6, a rechargeable power supply module 7, a charging protection circuit module 8, an air pressure height sensor 9, an acceleration sensor 10 and an electric quantity detection circuit module 11 are arranged in the handle mounting groove 100. The notch of handle mounting groove 100 is provided with control panel 3, last flexible operation button 31, the waterproof interface 32 and the electric quantity warning light 33 that charges that are provided with of control panel 3. In this embodiment, it is preferable that the processor 6 is a processor of model 66F 0815; the rechargeable power module 7 adopts a rechargeable lithium battery.
