Problems solved by technology

[0003] The current umbrellas generally have parasols or umbrellas. Generally, the sunshade umbrellas are made of opaque materials to shield the sun well. It is easy to block the line of sight when used, and the safety is poor. Umbrellas are generally made of plastic materials with good light transmission. , but it is not suitable for the strong sunlight in summer, so the versatility of parasols and umbrellas is poor

Embodiment 1

[0025] refer to Figure 1-3 , a self-changing umbrella, including an umbrella composed of an umbrella surface 1, an umbrella handle 2, an umbrella handle 3 and an umbrella rib 5. The outer wall of the umbrella handle 3 is provided with an arc-shaped concave surface 21, and the arc-shaped concave surface 21 is arranged to fit more closely. With the palm, it is easy to hold, and it is more comfortable to use than the traditional umbrella. The outer wall of the arc-shaped concave surface 21 is covered with a plush cover 4, and the plush cover 4 is set for easy holding, which improves the friction of the hand holding , to prevent sliding, the umbrella surface 1 is composed of an opaque layer 6 and a light-transmitting layer 7, the opaque layer 6 can be made of waterproof cloth material, and a double braided belt 9 is passed between the opaque layer 6 and the light-transmitting layer 7 The sewing connection is completed by the double braided belt 9, and the fixing is relatively fir...

Embodiment 2

[0029] refer to Figure 4 The light-transmitting layer 7 is a plastic layer 7 with a cavity 10 inside, the strain mechanism is located in the cavity 10, the strain mechanism includes a plurality of plastic rods 11 located in the cavity 10, and the outer wall of the plastic rod 11 is sleeved with a slide The sheet 12, the side of the sliding sheet 12 close to the double braid 9 is fixedly connected with the shrink cloth 13, the side of the double braid 9 near the sliding sheet 12 is fixedly connected with the memory metal foil 14, the memory metal foil 14 is made of nickel-titanium alloy Nitinol material is a shape memory alloy, which has a shape memory effect. Take a spring made of memory alloy as an example. Put this spring in hot water, and the length of the spring will elongate immediately. In cold water, it will return to its original state immediately, and the memory metal foil 14 is fixedly connected to the lower side wall of the slide plate 12 away from the end of the d...

Abstract

The invention discloses a self-changing umbrella, which comprises an umbrella composed of an umbrella surface, an umbrella handle, an umbrella handle and umbrella ribs, the umbrella surface is composed of an opaque layer and a light-transmitting layer, and the opaque layer and The light-transmitting layers are connected by double braided belts, and a strain mechanism is arranged in the light-transmitting layers. The advantage is that the present invention forms an umbrella surface by combining an opaque layer and a light-transmitting layer, and a deformable layer is arranged in the light-transmitting layer, which is usually used as a rain shield. Under the high-intensity light in summer, the temperature in the air rises, The deformed layer made of EVA resin material softens and extends in the high temperature environment outside in summer. The deformed layer is laid in the cavity to reduce the incidence of light and shade the sun. It has a strong ability to change. When the light weakens and the temperature drops, The deformed layer is restored to its original shape, avoiding blocking the line of sight, making it easy to observe through the plastic layer, and is suitable for rain and sun protection in summer, which is convenient and practical.

Description

technical field [0001] The invention relates to the technical field of umbrellas, in particular to a self-changing umbrella. Background technique [0002] Umbrella is a tool for shading the sun or sheltering from rain and snow. The materials used to make umbrellas usually include stretchable cloth, and other materials and tangling wires that can be used as skeletons. With hand, it is lifted during use, although the main purpose of umbrella when initial invention, be used to block sunlight, be most often taken as the instrument that the rainy day keeps off the rain now. Other uses of umbrellas include decorations, crutches and even weapons. [0003] The current umbrellas generally have parasols or umbrellas. Generally, the sunshade umbrellas are made of opaque materials in order to shield the sun well. It is easy to block the line of sight when used, and the safety is poor. Umbrellas are generally made of plastic materials with good light transmission. , but it is not suita...
