Electric foldable landscape umbrella

Abstract

The invention relates to an outdoor sun-shading rain-shading device, in particular to an electric foldable landscape umbrella. The electric foldable landscape umbrella comprises a standing column, a decorating column, a movable center column, an umbrella-top upper octangular support, an umbrella-top lower octangular support, a supporting arm, an umbrella cloth, a fabric shrinking system, a hydraulic oil cylinder, a framework stiffened plate and a control switch, wherein the fabric shrinking system is arranged at the lower portions of the supporting arm and the umbrella-top lower octangular support; the edges of the umbrella cloth are fixed at edge corners of the supporting arm, and the center of the umbrella cloth is fixed on a fabric flange plate of the standing column; the hydraulic oilcylinder is arranged at the portion, arranged at the lower portion of the movable center column, inside the decorating column; an oil cylinder fixing plate is arranged at the lower portion of the hydraulic oil cylinder and used for fixing the hydraulic oil cylinder on the framework stiffened plate. According to the electric foldable landscape umbrella, it is avoided that rainwater is splashed allaround, the service life of the umbrella cloth is prolonged, automatic unfolding and folding of the landscape umbrella is achieved, and the trouble of artificial shrinking is reduced.

Description

[technical field] [0001] The invention relates to outdoor sun-shading and rain-shielding equipment, in particular to an electric folding landscape umbrella. [Background technique] [0002] Landscape umbrellas are mostly used in outdoor scenic spots and some densely populated places. They are usually used to give people a place to avoid shade and rain when the sun is too strong and it is raining. Landscape umbrellas are relatively large and need to be fixed in a certain place all the time. place, but there are many times when it is necessary to fold up the umbrella cloth of the landscape umbrella. For example, when it does not rain at night, the umbrella cloth of the landscape umbrella will only block people from enjoying the starry sky. At this time, the umbrella cloth must be completely folded up. [0003] Now the general landscape umbrella is composed of multiple support arms, which push out the bottom corners of the umbrella cloth respectively, so as to spread the umbrell...

Problems solved by technology

[0003] Now the general landscape umbrella is composed of multiple support arms, which push out the bottom corners of the umbrella cloth respectively, so as to spread the umbrella cloth. When the umbrella cloth is folded, the bottom corner of the umbrella cloth is first moved to the end of the support arm. Then the outer end of the support arm is gathered towards the top of the landscape umbrella. When the umbrella is unfolded, when it rains, the rain will flow down the edge of the umbrella cloth. Umbrella cloth will still float outside and cannot be fully folded, which will cause rainwater to splash on pedestrians, affecting the appearance and user experience of landscape umbrellas. In addition, landscape umbrellas are usually large in size, and it is difficult to adopt the traditional shrinking and unfolding method , very inconvenient

[0004] For example, a large-scale umbrella with a lever principle disclosed in patent CN102150982A facilitates stretching and contraction by using the lever principle, but the structure is complicated, and long-term exposure to the outdoors will cause the umbrella body to age, and it is relatively difficult to maintain; a patent CN106617560A discloses a The electric folding umbrella uses the motor as the power source to control the stretching and shrinking of the umbrella body. Although the shrinking process is convenient, it needs to be charged, and it is prone to failure when it is used in a large outdoor umbrella. Therefore, a safe and convenient umbrella is required. Large umbrella that can be disassembled and repaired, and is easy to expand and contract
