Description
Technical Field
The invention relates to the technical field of shutters, in particular to a folding and unfolding mechanism of a blind and an electric shutter thereof.
Background
Blinds originate in china and are a form of window. The shutter has the blades that can adjust in a flexible way, compares in traditional cloth art (window) curtain, when playing better sunshade effect, receive and release more conveniently, and is brief generous, and occupation space does not accord with the brief wind that masses begin to pursue. The existing shutter mostly adopts a manual traction rope to realize the lifting and the rotation of the shutter blades, and the automation and the intellectualization are low. With the technological progress in recent years, electric blinds driven by motors are gradually developed, but the current electric blinds can not only adjust the rotation angle of the blind blades to open and close the blinds but also cannot lift the blinds, so that the lighting rate is low; the lifting of the blind and the angle adjustment of the louver blades are required to be carried out synchronously and cannot be carried out independently, so that the blind can be closed only when the blind is placed down, and the blind can be opened only when the blind is folded up. In order to solve the above-mentioned rigid mode of the electric blind, patent No. 201680034654.3, entitled "electric blind" discloses an electric blind, which includes a blind frame body composed of a head component and a column component, a rotary motor is installed in the head component, a link mechanism is configured in the column component, the link mechanism is composed of a plurality of rectangular link units which can be folded clockwise or anticlockwise, the ends of the blades of the blind are fixedly connected to the links at the top of each rectangular link unit, and the ends of the blades extend out of the links and are connected to the column component in a sliding manner through pulleys. When link mechanism anticlockwise folds, the folding promotion of every rectangular connecting rod that the blade can be along with, and the connecting rod of every rectangular connecting rod topmost can change at folding in-process angle simultaneously, drives the angle of blade then and expandes, realizes packing up of venetian blind, and the tripe is opened. When the connecting rod mechanism rotates clockwise, the shutter blind is lowered, and the shutter blind is closed. When the link mechanism continues to rotate clockwise, the blind only rises for a short distance, but the blind is in an open state, so that the blind is placed downwards, and the blind is opened.
However, the above patent realizes the mode that the louver is lowered and the louver blades are opened. However, the lifting of the venetian blind and the closing of the venetian blind are still carried out synchronously, namely, no matter the venetian blind is folded anticlockwise or clockwise, the height of the blades is matched with the rotation angle of the blades at the moment, namely, when the blades rise to the maximum, the angles of the blades are required to be completely opened, and when the blades fall to a half, the angles of the blades are required to be in a half-open state, so that a plurality of limitations are caused, and the venetian blind cannot meet requirements of various situations. This is not possible in the above patent, which requires that the blind be raised only half way, while requiring that the slats be fully closed or fully extended. Moreover, the process and the mode of the shutter which is converted into the half-releasing opening state from the downward releasing closing state are too complex and tedious, the conversion time is long, and the requirements of the fast-paced life on simplification, fast lifting and opening and closing of the shutter cannot be met.

The present embodiment provides a folding and unfolding mechanism for a blind, as shown in fig. 1 to 8, comprising a scissor lift mechanism 4, a blind clamp 7 and a rotating mechanism for controlling the rotation of the blind clamp 7; one end of the louver clamp 7 is clamped at the end of the louver 6 on the louver 3, and the other end is inserted into each scissor node of the scissor type lifting mechanism 4 and can rotate at the scissor node. The angle of rotation of each louver clamp 7, and thus each louver 6, can be controlled by a rotating mechanism. When the blind 3 needs to be folded, the rotating mechanism controls the blind 6 to rotate to the horizontal state, meanwhile, the scissor-type lifting mechanism 4 is folded, the scissor-type nodes on the scissor-type lifting mechanism 4 can drive each blind clamp 7 to move upwards, then the blind 6 is stacked together, and then the blind 3 is folded. When the blind 3 needs to be placed downwards, the scissor-type lifting mechanism 4 extends, and meanwhile, the rotating mechanism controls the blind 6 to rotate to a vertical state, so that the blind 6 is closed mutually, and closing is completed. Because the rotating mechanism and the scissor-type lifting mechanism 4 independently control the rotation of the shutter 6 and the lifting of the shutter 6, the angle adjustment and the lifting of the shutter 6 are not interfered with each other, and then the requirements of various situations can be met, for example, when the shutter 3 is folded to a half, the shutter 6 can be completely closed, completely opened or half opened, or when the shutter 3 is completely lowered, the shutter 6 is still in an open state (horizontal state), so that the purpose of semi-shading is achieved.
In this embodiment, as shown in fig. 1 to 8, the scissor lift mechanism 4 includes a plurality of cross connecting rods 5; two mutually crossing connecting rods 5 form a group and are hinged by a shutter clamp 7.

When the polygonal rotating shaft 8 rotates, the large bevel gear 11 can drive the small bevel gear 12 to rotate, then the rotation of the polygonal rotating shaft 8 in the horizontal direction is converted into the rotation of the small bevel gear 12 in the vertical direction, the louver clamp 7 drives the louver 6 to vertically rotate, and the angle adjustment of the louver 6 is realized. Preferably, referring to fig. 2 to 5, the bevel gear assemblies are arranged at intervals and are arranged in a staggered manner with respect to the bevel gear assemblies on the polygonal rotating shafts 8 on opposite sides, that is, one of the louver clamps 7 on both sides of one louver 6 has a large bevel gear 11, and the other has no large bevel gear 11, while the other one of the louver clamps 7 on the same side of two vertically adjacent louvers 6 has a large bevel gear 11, and the other one has no large bevel gear 11, so that the number of bevel gear assemblies used is reduced, and the use cost is reduced. And the arrangement mode that the bevel gear components are staggered mutually can ensure the lifting stability of the blind 3. The polygonal rotating shaft 8 can be a triangular shaft, a rectangular shaft and a hexagonal shaft, preferably a hexagonal shaft, and the polygonal rotating shaft 8 can drive the large bevel gear 11 to rotate and can ensure that the large bevel gear 11 slides on the polygonal rotating shaft 8, so that the rotation and the lifting of the louver clamp 7 are not interfered with each other.
