    Hello
    The meteorological situation in Poland has made me wonder about the possibility of retrofitting a garden umbrella with an electric motor that will automatically fold the umbrella in high winds. The umbrella has such a classic market cob umbrella. All I would need is a suitable motor, as I can handle the automation without any problems.
    I have a HomeAssistant at home with a wind speed sensor plugged in. If the wind speed exceeds the set value, the motor will fold the umbrella.
    I've been unaware of this a few times and the umbrella has been blown over. I'm afraid it might fly into my terrace windows one day and cause more damage.....
    The weather situation today is so uncertain that such automation is the ideal solution for the frequent changeability of weather conditions.

    How about a motor/drive from the car wipers instead of a crank?
    You could also mess around with a motor from electric windows.

    .
    An idea worth considering. It would probably be possible to fit it somehow but the problem could be watertightness. A motor outdoors needs to be watertight to some degree.

    Well, it's a matter of making him a case/cover, perhaps even from a fitted plastic box? It's a simple matter.
    It doesn't have to be super-tight either, just protected from direct water infiltration (rain), it's not easy in a car either...
    The most problematic part is the connection between the gear shaft and the umbrella drive.
    An example of a very effective drive, of course to use the gear motor itself, without the tin mechanism - the drive contains electronics to control the increase in current when the end positions are reached - no end switches :)
    example
    And the important thing-this drive is very tight :) .

    You can do it yourself with a pair of pliers... More data would be rather useful.
    What maximum torque is needed to unfold or fold the umbrella?
    Amperometers instead of limit switches?
    Ok , but to what extent adjustable? How much does the motor draw? You can theorise all over the world. It either works or it doesn't. The umbrella will either fail to fold and unfold or the motor will roz.....i the umbrella. Maybe if it's a matter of folding and unfolding it will only need a pinion lock release mechanism? Maybe, maybe, maybe... Photographs of the mechanism, force data measured approximately e.g. with a torque spanner etc. are rather necessary to make reasonably accurate hints or suggestions to solve the issue.

    An electric actuator would pass the test best. That is, the kind that were used in Sat antenna turntables.
    The windscreen wiper motor turned a screw ( M10 x 1000mm ) on which a nut with a handle moved. There was also a version where the motor turned a sleeve with a nut and the screw had a handle. The way the motor was switched on was arbitrary.

    How about a sunroof motor from a toyota would be ok? I have a working one we can make a deal

Topic summary

The discussion revolves around retrofitting a garden umbrella with an electric motor for automatic folding in high winds, prompted by concerns over potential damage from strong weather conditions. Various motor options are suggested, including car wiper motors, electric window motors, and sunroof motors from Toyota. Participants emphasize the importance of waterproofing the motor and propose using a protective casing. The connection between the motor and the umbrella's drive mechanism is highlighted as a critical challenge, with suggestions for using gear motors with built-in electronics to manage current and prevent damage. The need for torque specifications and additional data for effective implementation is also noted.
