Abstract

The utility model discloses a blind-guide crutch with electricity generation and electricity storage. The blind-guide crutch comprise a blind-guide switch (1), a pressing plate (2), a gear speed changer (3), an electric generator (4), a controller (5), a storage battery (6), an ultrasonic sensor (7), a speaker (8), a changeover switch (9), a laser sensor (10), a photosensor (11), an LED (light-emitting diode) lamp (12), a time telling switch (13), a timing circuit board (14), a timing power supply (15), a telescopic rod (16) and a handle (17). The blind-guide switch is opened to be communicated with the controller, and the pressing plate is pressed to transfer the power to the gear speed changer through a gear column, so as to lead the electric generator to generate electricity. Electrical energy generated by the electric generator is transferred to the ultrasonic sensor through the controller. When the ultrasonic sensor detects a barrier ahead within the fan-shaped range of 0.5m to 2m, the ultrasonic sensor sends signal to the controller, and the signal is processed by the controller and is connected with the speaker to give an alarm. A timing device of the blind-guide crutch can tell the time by voice, so as to remind the current time for the blind.
