Description

Technical Field

[0001] The invention relates to an umbrella, and in particular to an electric umbrella structure which can be opened and folded automatically. Background Art

[0002] When using early umbrellas, the user must hold the handle with one hand and push the ribs up to a certain position with the other hand so that the umbrella cloth opens with the ribs, and pulls the ribs down when folding. Since this type of umbrella must be opened and closed with both hands, if the user has one hand to hold objects or is injured and inconvenient to use the umbrella, it will be inconvenient to use the umbrella. Therefore, someone designed an umbrella with a button on the handle. Pressing the button can automatically open the umbrella, but it does not have an automatic umbrella folding function, and both hands must be used to fold the umbrella, which is still inconvenient to use. Therefore, in recent years, umbrellas that can open and close automatically have been designed.

[0003] As disclosed in the Chinese invention patent announcement No. CN109303396A, the "opening and closing structure, middle rod and umbrella" is a conventional automatically opening and closing umbrella, wherein the opening and closing structure is used to open or close the umbrella, wherein the umbrella comprises a middle rod, an upper nest provided at one end of the middle rod, and a lower nest slidably sleeved on the other end of the middle rod, wherein the opening and closing structure comprises a pulley and a first fixed pulley provided in the upper nest, a pull rope, and a second fixed pulley provided in the lower nest, wherein the pulley and the first fixed pulley are arranged at intervals, and the first fixed pulley and the second fixed pulley are arranged oppositely, wherein the pull rope passes through the middle rod and sequentially passes around the pulley, the second fixed pulley and the first fixed pulley, wherein the opening and closing structure further comprises a first gear, a worm gear meshing with the first gear, and a motor, wherein the first gear is sleeved on a connecting rod of the pulley, and the motor is connected to the worm gear The middle rod includes a control component, which includes a button arranged on the handle, a circuit board, a switch and a power-off component all arranged in the handle, the switch and the power-off component are electrically connected to the circuit board, the button can touch the switch, the button includes an umbrella opening button and an umbrella closing button, the control component also includes a battery, two terminals arranged on the circuit board, and a spring-type wire, one end of the wire passes through the middle rod and is connected to the motor, the other end of the spring-type wire is connected to a terminal, and the battery is connected to the other terminal, the middle rod includes an outer tube, at least one middle tube and an inner tube, the inner tube, at least one middle tube and the outer tube are slidably connected in sequence from the inside to the outside, and a spring is also provided in the middle rod, the spring is accommodated in the inner tube, and the spring-type wire and part of the pull rope pass through the spring. When in use, the umbrella opening button is pressed to connect the circuit, so that the motor rotates forward to drive the worm, the first gear, the pulley, the second fixed pulley and the pull rope to move, so that the lower nest moves in the direction of the upper edge of the middle rod close to the upper nest, so as to achieve the purpose of opening the umbrella; the umbrella closing button is pressed to connect the circuit, so that the motor rotates reversely to drive the worm, the first gear, the pulley, the second fixed pulley and the pull rope to move, so that the lower nest moves in the direction of the upper edge of the middle rod away from the upper nest, so as to achieve the purpose of closing the umbrella.

[0004] However, the conventional automatic opening and closing umbrella, wherein the rod comprises an inner tube, at least one middle tube and an outer tube which are slidably sleeved from the inside to the outside in sequence, and thus the inner space of the inner tube is limited, and it is difficult to simultaneously insert the spring, the spring-type wire and the pull rope in the inner space, resulting in difficulty in assembly, poor assembly efficiency and high manufacturing cost. Furthermore, when the umbrella is opened and closed, since the spring-type wire and the pull rope are inserted in the spring, the spring-type wire is easily worn in the middle rod or entangled with or interfered with the spring, causing the opening and closing of the umbrella to pause, slow down or get stuck, etc., which is indeed necessary to improve it.
