In outdoor leisure spaces, Patio Umbrellas are an important tool for sunshade and rain shelter. Their convenience and practicality are increasingly favored by people. In particular, those Patio Umbrellas equipped with automatic opening and closing mechanisms have brought users an unprecedented user experience with their intelligent design. This article will explore in depth how the automatic opening and closing mechanism of Patio Umbrellas works.
The automatic opening and closing mechanism of Patio Umbrellas mainly relies on the sensor sensing principle, circuit control mechanism and safety protection mechanism. These mechanisms work together to enable the patio umbrella to automatically open or close according to changes in the external environment, which is both convenient and practical.
The key to automatic opening and closing umbrellas lies in sensors. Common sensors include light sensors and raindrop sensors.
Light sensor: Determine whether the umbrella needs to be opened by sensing the intensity of light. When the light intensity is lower than a certain threshold, the light sensor will trigger a signal to notify the umbrella to open. In this way, on cloudy or rainy days, the light sensor can sense the change in light and automatically open the umbrella to provide users with sunshade or rain shelter.
Raindrop sensor: It determines whether the umbrella needs to be opened by sensing the presence of raindrops. Raindrop sensors usually use resistive sensors or capacitive sensors. When raindrops touch the sensor, the sensor generates an electrical signal, which controls the opening and closing of the umbrella through the circuit. This sensor can respond quickly on rainy days to ensure that the courtyard umbrella is opened in time and protect users from rain.
After the sensor senses the signal that the umbrella needs to be opened, the circuit control mechanism is needed to open the umbrella. The circuit control mechanism usually consists of a power supply, a switch and a motor.
Power supply: Provides energy for automatic opening and closing of the umbrella. Common power supplies include dry batteries and lithium batteries. The power supply is usually installed in the umbrella handle for easy replacement and charging.
Switch: A device that controls the opening and closing of the umbrella. The switch usually consists of a button or a touch screen, and the user can control the state of the umbrella by operating the switch.
Motor: It is a key component to realize the opening and closing of the umbrella. The motor is usually installed at the connection between the umbrella handle and the ribs, and the umbrella can be opened and closed by rotating the ribs. The motor is connected to the switch through a circuit control mechanism. When the switch signal is received, the motor controls the rotation of the ribs according to the signal, thereby realizing the automatic opening and closing of the umbrella.
In order to ensure the safety and stability of the automatic opening and closing umbrella, some safety protection mechanisms are usually added.
Windproof device: In order to prevent the umbrella from being damaged or blown over in strong winds, the windproof device is usually implemented by adding a spring device between the umbrella and the ribs or increasing the wind-resistant design of the umbrella. These devices can enhance the stability of the umbrella and ensure normal use in bad weather.
Automatic folding device: For easy storage and carrying, the automatic folding device will fold the umbrella into a smaller volume when the umbrella is closed. In this way, users can easily put the garden umbrella into a bag or a handbag for easy carrying and storage.
