Description

This application relates to the technical field of umbrellas, and particularly to screwless electric umbrellas.

Umbrellas, which are the most commonly used everyday items, have functions such as windproof, rainproof, and UV shielding. Folding umbrellas are popular because they are light, compact and convenient to store. However, in the early days, the umbrella could be opened by pushing the ribs up to a certain position by hand, and when it rained suddenly, the umbrella could get wet late. This allows you to design an umbrella with a button on the handle, and when you press this button you can automatically open the umbrella, but it does not have an automatic closing function and you can hold the umbrella with both hands when you try to get on. You can get inside the car by closing it, but in this short time you got wet in the rain.

In addition, since there is only one pull string for a conventional automatic umbrella, this pull string withstands the tensile force of opening and closing the umbrella, is easily cut by pulling, and after opening, the middle rod of the umbrella shakes.

In the technical means of the embodiment of the present application, the automatic opening / closing function of the umbrella is realized by rotating the take-up reel in the forward / reverse direction via the forward / reverse rotation of the motor. Specifically, it is as follows.

When the open umbrella button of the forward / reverse rotation button on the electric hand is pressed, the motor rotates in the forward direction to rotate the take-up reel in the forward direction, and when the take-up reel rotates in the forward direction, the second take-up rim of the take-up reel (that is, As the first drawstring) unwinds, the first take-up rim of the take-up reel (ie, the second drawstring) begins to take up, the second drawstring pulls up the middle tube; when the middle tube is moved up. , The distance between the inner tube pulley holder and the middle tube pulley holder increases, and in the action of the third drawstring, the outer tube is moved up; when the outer tube is moved up, the middle tube pulley holder and the outer tube The distance to the pulley holder increases, and in the action of the fourth drawstring, the lower locro is moved up; when the lower locro moves up, the ribs are opened.

In contrast, when the closing button of the forward / reverse rotation button on the electric hand is pressed, the motor reverses, the reverse rotation of the motor reverses the take-up reel, and when the take-up reel reverses, the take-up reel As the first take-up rim (ie, second pull string) winds up, the second take-up rim (ie, first pull string) begins to unwind, the first pull string pulls down the middle tube; the middle tube goes down. When moved, the distance between the inner tube pulley holder and the middle tube pulley holder becomes smaller, and the outer tube can be moved down by the action of the third drawstring; when the outer tube is moved down. , The distance between the inner tube pulley holder and the outer tube pulley holder is reduced, and in the action of the closing umbrella spring on the rib, the lower locro is moved downward, and at the same time, the outer tube is powered to move downward; When the lower locro is moved down, the ribs are closed.

By taking the above technical measures, as an advantageous effect of the present application, the present application rotates the take-up reel forward and reverse by the forward and reverse rotation of the forward and reverse rotation motor without the need for a screw, and significantly reduces the parts. It reduces, reduces the volume of the entire umbrella, promotes the winding and unwinding of the drawstring, and in the action of the drawstring and the closed umbrella spring, the inner tube upper pulley holder, middle tube pulley holder, outer tube pulley holder in the umbrella. By adjusting the distance between the three parties, the automatic opening and closing function of the umbrella is realized. In this application, several drawstrings are provided, the force received by the drawstrings is dispersed, and the load of tensile stress applied to the drawstrings is reduced so that the drawstrings are not easily broken by tension and the middle rod is opened. Is stable, does not shake easily, and has a long life.
