Full-automatic umbrella folding and unfolding operation mechanism

Abstract

A full-automatic umbrella folding and unfolding operating mechanism comprises an umbrella handle, a motor in the umbrella handle, a power supply module, a circuit board, a screw rod extending into an umbrella shaft, and a nut arranged on the screw rod in a matching manner; a main switch and a positive and negative rotation switching circuit are arranged on the circuit board; the power supply module is connected with the main switch; the main switch is connected with the positive and negative rotation switching circuit; the positive and negative rotation switching circuit is connected with the motor; and the positive and negative rotation switching circuit is operated by a switch button on the umbrella handle; and the main switch protrudes from and extends out of the umbrella handle or the main switch is operated by a switch knob on the umbrella handle. When an umbrella is folded or unfolded in normal times, the main switch is switched to be in a turn-off state, so that the unnecessary electricity consumption of the power supply module can be avoided; and when the voltage is low or the main switch is turned off, the switch button is started to control the positive and negative rotation switching circuit to be in the turn-off state, the function of folding and unfolding the umbrella by hands easily can be achieved, the embarrassment that the umbrella cannot be in emergency use under the condition that the full-automatic umbrella folding and unfolding function fail fails, the automatic umbrella folding and unfolding function is more complete, and the use is more convenient and more flexible.

Description

technical field [0001] The invention relates to an umbrella, in particular to an operating mechanism for a fully automatic opening and closing of an umbrella that can be fully opened and fully retracted. Background technique [0002] In recent years, due to the erratic climate, everyone has the habit of carrying an umbrella to prevent the sudden heavy rain from being drenched. But the early stage umbrellas need to push the umbrella frame up to a certain position by hand to open the umbrella. In case of a sudden rain, it is often too late to open the umbrella and get wet. Therefore, someone has just designed a kind of umbrella, is provided with a button at the handle, presses this button and can automatically open umbrella and does not have automatic umbrella closing function, still needs both hands to fold umbrella and just can enter when wanting to take a car. In the car, it is still vulnerable to rain in this short period of time, so it loses the convenience of the umbrel...
