Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention and the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Referring to fig. 1 to 3, an embodiment of the present invention provides a controllable sun blind, including a rotating shaft 1, a rotating disc 2, a traction member 5, and a blind mat; the rotating shaft 1 is horizontally arranged at the top, the rotating disc 2 is in transmission connection with the rotating shaft 1, a plurality of connecting ends 3 are fixedly arranged around the rotating disc 2, the connecting ends 3 are arranged around the rotating disc 2 in a biased manner, and the top ends of a plurality of traction pieces 5 are respectively connected with the connecting ends 3; the shutter curtain mat is formed by vertically connecting and arranging a plurality of transversely arranged curtain sheets 4, each curtain sheet 4 corresponds to one traction piece 5, and the traction pieces 5 can act on the curtain sheets 4, so that the traction pieces 5 drive the curtain sheets 4 to be opened upwards when being upwards pulled under the action of the rotary disc 2.

The invention is characterized in that the independent opening and closing control of the areas with different heights of the whole venetian blind mat is realized through the matching of the turntable 2 and the traction piece 5.

Referring to fig. 1 to fig. 2, the specific working principle is as follows:

when the turntable 2 is rotated to a position where all the link ends 3 are located at a low position, generally the link ends 3 are arranged along the lower half circumference of the turntable 2, all the curtain sheets 4 are closed at this position, and this position is also generally the initial position of the turntable 2. In this position, the traction element 5 is not in contact with the curtain 4, and there is no interaction between the two.

When a certain area of the blind mat needs to be opened partially, the rotating shaft 1 can be controlled to rotate, and the rotating disc 2 is driven to rotate. When the rotary table 2 rotates, the traction piece 5 corresponding to the connecting end 3 positioned at the highest position firstly generates a traction effect with the corresponding curtain sheet 4 to drive the curtain sheet 4 to start to be opened upwards. Along with the rotation of the rotary disc 2, the connecting ends 3 are sequentially lifted upwards, and the corresponding curtain sheets 4 are also opened according to the corresponding sequence. When the link end 3 runs to the highest point, the corresponding curtain sheet 4 is also opened to the maximum extent. Since the connecting ends 3 arranged on the rotary disc 2 also pass through the highest point in turn during the rotation of the rotary disc 2, the corresponding curtain sheets 4 are also opened to the maximum extent in turn and then closed again until being completely closed.

The resulting effect is: the whole blind mat is sequentially opened from different areas according to the corresponding sequence, and is just like waves. Therefore, as long as the rotation angle of the rotary disc 2 is controlled, one direction is always corresponding to a certain area of the blind mat, thereby realizing the independent controllable opening and closing of the area with specific height. For example, when indoor personnel need to independently open the middle height of the blind mat and close other areas, the connecting end 3 in the middle part only needs to be rotated to the highest point.

The specific structure of the blind mat has two application scenes of indoor use and outdoor use. In this embodiment, the indoor blind is explained first:

referring to fig. 3 in detail, preferably, the curtain sheets 4 are connected in series by ladder cords 6, the tail portions of the curtain sheets 4 are provided with receiving through holes, the pulling ropes 7 penetrate through the receiving through holes of all the curtain sheets 4, the bottom ends of the pulling ropes 7 are connected with the bottommost curtain sheet 4, and the top ends of the pulling ropes 7 are connected with a winding roller 18.

The specific structure of the blind mat in this embodiment is essentially not much different from the prior art blind. Under normal conditions, all the curtain sheets 4 can droop and close under the action of the self-weight of the front part.

Besides the function of realizing the partial opening and lighting, the blind mat also has the function of completely accommodating and opening. When the winding drum 18 rotates, the cord 7 is wound so as to pull the curtain sheet 4 to be stored from the bottom upward, and the entire blind mat is stored from the bottom upward. The rotating winding drum 18 may be manually operated, typically by means of a bead chain or the like, to rotate the winding drum 18, as is known in the art. This solution is usually applied to the indoor side of a glazing or to the interior of a glazing partition.

For the interaction structure of the traction piece 5 and the curtain sheet 4, preferably, an opening-closing perforation is arranged in front of the tail part of the curtain sheet 4, the corresponding traction piece 5 passes through the opening-closing perforation of the corresponding curtain sheet 4, and a traction head with the size larger than that of the opening-closing perforation is arranged below the traction piece 5 positioned below the opening-closing perforation.

When the traction piece 5 is pulled upwards under the action of the turntable 2, the traction head can be lifted upwards until contacting with the curtain sheet 4, and the curtain sheet 4 can be driven to be opened by further lifting of the traction piece 5.

As a further preference, the pulling member 5 is a steel wire, which extends to the lower part of the pulling head, and the bottom end of the steel wire is connected with a second sliding block (not shown); two sides of the blind mat are provided with second guide rails 12, and the second sliding blocks are connected with the second guide rails 12 in a sliding way.

When the traction element 5 is a wire, the figures of the present description also provide a crown block at the top of the column to assist its guidance, but this is not a necessary feature.

The steel wire is used as the traction piece 5, so that the space occupied by the traction piece 5 can be greatly reduced, each curtain sheet 4 can be controlled more conveniently, and the overall control effect is more refined. However, the steel wire is a flexible material, and is easy to be wound and knotted. Therefore, the bottom end of each steel wire traction piece 5 is connected with a second sliding block, and the structure scheme is convenient for wire arrangement. Moreover, the bottom end positions of all the traction members 5 are staggered, so that the second sliding blocks are also staggered, and only one second guide rail 12 is needed to accommodate all the second sliding blocks.

Preferably, the device also comprises a top beam 9 and an upright post 8; the upright posts 8 are fixedly arranged on two sides, and the top beam 9 is fixed on the top between the upright posts 8; the rotating shaft 1 is arranged on the top beam 9, and the top end of the curtain mat is connected with the top beam 9; the pulling element 5 extends along the uprights 8 on both sides. The members located on both sides of the blind mat, such as the second guide rail 12 and the second slider, may be housed in the column 8 to be shielded.

In order to improve the degree of automation, it is more preferable that the rotating shaft 1 is in transmission connection with an opening and closing control motor 10, and the opening and closing control motor 10 drives the rotating disc 2 to rotate. When indoor personnel need to control the opening of the blind mat at any part, only the opening and closing control motor 10 needs to be controlled.

Since the winding drum 18 also needs to rotate in accordance with the state of storing the blind mat, it is preferable that the dial 2 and the winding drum 18 are coaxially connected to the rotation shaft 1, and clutches (not shown) are provided between the dial 2 and the rotation shaft 1 and between the winding drum 18 and the rotation shaft 1. Particularly, the partial opening and the complete storage of the blind mat are two completely independent actions, the actions cannot be carried out synchronously, one motor can be saved by adopting clutch control, and the manufacturing cost is reduced.

Of course, as a sub-alternative, as shown in fig. 3, the winding drum 18 is connected to a storage motor 11 in a transmission manner, and the storage motor 11 drives the winding drum 18 to rotate independently. The dual motor drive scheme is more costly but relatively simple to maintain.

Example two

The only difference between this embodiment and the first embodiment is: the blind mat of the embodiment adopts the scheme of an outdoor sun-shading curtain, and focuses more on the performances of strength, wind resistance and the like.

Referring to fig. 4 to 7, in particular, preferably, the curtain sheets 4 are connected in series by the scissors assemblies 13 at two sides of the blind mat; the scissor assembly 13 consists of scissor rods, the scissor rods are hinged in the middle in a crossed manner to form a scissor unit, and the ends of the scissor unit are hinged and connected in series end to form the scissor assembly 13; the bottom end of the scissor assembly 13 is connected with a pull rope 7, and the top end of the pull rope 7 is connected with a winding roller 18; two sides of the blind mat are provided with first guide rails 14, and the intersection of the scissors assembly 13 is provided with a first sliding block (not shown), which is connected with the first guide rails 14 in a sliding way; the tail parts of the two ends of the curtain sheet 4 are hinged with the cross point of the scissor assembly 13, so that the curtain sheet 4 can open and close and swing around the cross point of the scissor assembly 13; two ends of the curtain sheet 4 are also provided with supporting terminals 15, so that the supporting terminals 15 are overlapped on the corresponding scissor rods under the action of self weight of the curtain sheet 4.

Unlike the indoor solution, the curtain sheet 4 of this embodiment can be made of a larger and stronger material. And the storage structure is also different from the indoor scheme, and a scissor fork structure is adopted. When the pull rope 7 is put down, the scissor assembly 13 extends downwards, and a first sliding block is matched with the first guide rail 14 in the whole process, so that the scissor assembly has strong wind resistance. When the pull rope 7 is retracted, the scissor assembly 13 will be retracted upwards, and the scissor rod will support the support terminal 15, so that the curtain sheet 4 is automatically opened and retracted in the retracting process, and cannot be mutually locked.

In detail, referring to fig. 7, when the control part is opened, the control dial 2 is rotated to open the corresponding curtain sheet 4 by the pulling member 5, as in the same embodiment. During partial opening, the support terminal 15 may be separated from the scissor lever.

Preferably, the surface of the tail part of the curtain sheet 4 is provided with a sunken connecting groove 16, the front part of the curtain sheet 4 is provided with a connecting part 17 matched with the connecting groove 16, and the connecting part 17 is embedded in the connecting groove 16 when the curtain sheet 4 is closed, so that the matching is better sealed, and external rainwater, dust and the like are prevented from entering.

Other technical features in this embodiment, such as the structure of the traction member 5 and the automation scheme of the driving system, are completely the same as those in the first embodiment, and are not described herein again.

According to the controllable sun-shading blind, through the traction control of the special rotary disc 2, the whole blind mat can be opened independently in different areas along with different rotation angles of the rotary disc 2, so that the opening of the areas with different heights of the blind mat can be controlled independently only by adjusting the angle of the rotary disc 2. And the structure is simple, and the debugging is convenient. The traction piece 5 can be made of steel wires, is easy to lay and is convenient to install. Meanwhile, the blind mat has two structural schemes of indoor and outdoor, and the indoor scheme is light and low in cost; the outdoor scheme has high strength and is wind-resistant and rain-proof. And has an automated electrical scheme.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
