Description

Technical Field

[0001] The invention relates to the technical field of umbrellas, in particular to a novel automatic umbrella. Background Art

[0002] Umbrellas are the most commonly used daily necessities, with functions such as wind protection, rain protection, and sun protection. Among them, folding umbrellas are popular among users because of their small size and convenient storage. However, in the early days, umbrellas needed to be pushed up to a certain position by hand before they could be opened. Once a sudden rainstorm came, it was often too late to open the umbrella and get wet. Therefore, someone designed an umbrella with a button on the handle. Pressing the button can automatically open the umbrella, but it does not have the function of automatically closing the umbrella. When you want to take a car, you still need to use both hands to fold the umbrella back before you can get into the car. In this short period of time, you will get wet by the rain.

[0003] In addition, the existing automatic umbrella has only one pull rope, which bears the pulling force of opening and closing the umbrella and is easy to be broken.

[0016] Working principle of the present invention:

[0017] The invention realizes the self-opening and self-closing functions of the umbrella by driving the reel to rotate forward and reversely through the forward and reverse rotation of the motor.

[0018] Press the umbrella opening button of the forward and reverse buttons on the electric umbrella head, the motor rotates forward to drive the take-up wheel to rotate forward, the take-up wheel rotates forward, the second winding groove of the take-up wheel (i.e. the first pull rope) releases the line, and at the same time, the first winding groove of the take-up wheel (i.e. the second pull rope) starts to reel in the line, and the second pull rope pulls the middle tube upward; the middle tube moves upward, the distance between the inner tube pulley seat and the middle tube pulley seat increases, and under the action of the third pull rope, the outer tube moves upward; the outer tube moves upward, the distance between the middle tube pulley seat and the outer tube pulley seat increases, and under the action of the fourth pull rope, the lower nest moves upward; the lower nest moves upward, and the umbrella frame opens.

[0019] On the contrary, when the umbrella folding button of the forward and reverse buttons on the electric umbrella head is pressed, the motor reverses, and the motor reverses to drive the take-up wheel to reverse, the take-up wheel reverses, the first winding groove (i.e., the second pull rope) of the take-up wheel, and the second winding groove (the first pull rope) start to reel in the line, and the first pull rope pulls the middle tube downward; when the middle tube moves downward, the distance between the inner tube pulley seat and the middle tube pulley seat becomes smaller, and under the action of the third pull rope, the outer tube can move downward; when the outer tube moves downward, the distance between the middle tube pulley seat and the outer tube pulley seat becomes smaller, and under the action of the umbrella folding spring on the umbrella frame, the lower nest moves downward, and also provides power for the outer tube to move downward; when the lower nest moves downward, the umbrella frame is folded.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are as follows: the present invention drives the reel to rotate forward and backward through the forward and reverse rotation of the forward and reverse rotation motor, promotes the reeling and unreeling of the pull rope, and adjusts the distance between the pulley seat on the inner tube, the pulley seat on the middle tube, and the pulley seat on the outer tube in the umbrella under the action of the pull rope and the umbrella retracting spring, thereby realizing the self-opening and self-retracting functions of the umbrella. The present invention is provided with multiple pull ropes, which disperse the bearing force of the pull ropes, reduce the tensile strength of the pull ropes, make the pull ropes not easy to be broken, and after being stretched out, the middle rod is stable, not easy to shake, and has a long service life.

[0021] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

[0066] When the forward / reverse button 124 on the electric umbrella head 1 is pressed, the forward / reverse motor 122 rotates forward to drive the take-up wheel 131 to rotate forward. The take-up wheel 131 rotates forward, and the second winding groove 133 (i.e., the first pull rope 61) of the take-up wheel 131 releases the wire. At the same time, the first winding groove 132 (i.e., the second pull rope 62) of the take-up wheel 131 starts to reel in the wire. The second pull rope 62 pulls the middle tube 31 upward. When the middle tube 31 moves upward, the distance between the pulley seat 221 on the inner tube and the pulley seat 321 of the middle tube increases. Under the action of the third pull rope 63, the outer tube 41 moves upward. When the outer tube 41 moves upward, the distance between the pulley seat 321 on the middle tube and the pulley seat 421 of the outer tube increases. Under the action of the fourth pull rope 64, the lower nest 45 moves upward. When the lower nest 45 moves upward, the umbrella frame 5 opens.
