Description

Large-span outdoor electric blind

Technical Field

The utility model belongs to electronic tripe curtain field especially relates to an outdoor electronic tripe curtain of large-span.

Background

The electric blind curtain is widely used and comprises an electric cylinder and a plurality of blades arranged from top to bottom, wherein the electric cylinder drives the blades to synchronously rotate through a transmission mechanism, so that the light inlet quantity of light is adjusted, shading adjustment is carried out, the indoor natural lighting degree can be accurately adjusted, the light taking-in is adjusted according to the needs of users, and better visual comfort is realized. The electric blind can effectively block ultraviolet rays and direct sunlight, and prevent the generation of greenhouse effect, thereby being beneficial to the heat preservation and insulation effect of the whole building and being beneficial to energy conservation.

The electric blind used for outdoor sun shading has large span, namely, has larger width, and the length of the corresponding blade is longer, and the blade is easy to bend under the action of gravity. For overcoming the crooked problem of blade, the current practice is thickening and widens the blade, makes blade intensity increase, but if excessively thicken and widen the blade, can make the material cost increase by a wide margin undoubtedly to increase blade weight by a wide margin, need drive the blade rotation with high-power electric jar, lead to the electric jar cost also to increase by a wide margin. Therefore, due to cost, the blades cannot be made very thick and very wide, so that the maximum length of the existing blades cannot exceed 4 meters, otherwise the blades can be bent, and correspondingly, the span of the electric blind can only be 4 meters at most, and the span is small. When the window that sunshade span demand was more than 4 meters was used, just need the electronic blind more than two to carry out the sunshade side by side, like 6 meters sunshade span demand, just need adopt the electronic blind of 3 meters of two spans to carry out the sunshade side by side, form great space between the adjacent electronic blind, this space can't carry out the shading and adjust, not only can influence the sunshade effect, still can reduce pleasing to the eye degree.

Therefore, the electronic blind curtain that is used for outdoor sunshade of current has the less defect of span, when the great place of sunshade span demand was used, need use the electronic blind curtain more than two, and the sunshade effect is relatively poor, pleasing to the eye degree is relatively poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an outdoor electronic blind of large-span.

In the aforementioned large-span outdoor electric blind, the second rotating shaft is connected to the blades through the bracket.

Compared with the prior art, the utility model discloses increased bearing mechanism on the basis of current electronic tripe curtain to drive mechanism's structure has been optimized. The stand passes through the keysets and links to each other with the blade, the bearing effect that has played the blade to prevent that the blade is crooked, make electronic blind can adopt longer blade to make, obtain the electronic blind that the span is big, when the great place of sunshade span demand was used, electronic blind can satisfy the span demand, and is not only effectual like this, and pleasing to the eye degree is better moreover. The utility model discloses a drive mechanism is close to the middle part of blade, and the transmission is more steady. In addition, the electric blind for outdoor use is large in area generally, bears large wind pressure when windward, and the bearing mechanism can effectively support the blades, so that the blades are reduced to shake, and noise is reduced.

Therefore, the utility model has the advantages of the span is great, when the great place of sunshade span demand is used, also only needs an electronic blind, and the sunshade effect is equally better, pleasing to the eye degree is equally better.
