Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of 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 some embodiments of the present invention, and not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Example 1

Referring to fig. 1 to 3, the embodiment of the invention provides a controllable sunshade blind, which comprises a rotating shaft 1, a rotating disc 2, a traction piece 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 an offset manner, and the top ends of a plurality of traction pieces 5 are respectively connected with the plurality of connecting ends 3; the blind mat is formed by connecting and arranging a plurality of transversely arranged curtain sheets 4 up and down, each curtain sheet 4 corresponds to one traction piece 5 respectively, and the traction pieces 5 can act on the curtain sheets 4, so that the traction pieces 5 drive the curtain sheets 4 to open upwards when being pulled upwards under the action of the rotating disc 2.

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

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

When the turntable 2 is rotated until all the connection ends 3 are positioned at a low position, the connection ends 3 are generally arranged along the lower half circumference of the turntable 2, and all the curtain sheets 4 are closed at this position, which is also generally the initial position of the turntable 2. In this position, the traction member 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 partially opened, the rotating shaft 1 can be controlled to rotate, and the turntable 2 is driven to rotate. When the turntable 2 rotates, the traction piece 5 corresponding to the connecting end 3 positioned at the highest position firstly generates traction action with the corresponding curtain sheet 4 to drive the curtain sheet 4 to start to open upwards. Along with the rotation of the rotary table 2, the connecting ends 3 are sequentially lifted upwards, and the corresponding curtain sheets 4 are opened in a corresponding sequence. When the connecting 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 turntable 2 pass through the highest points in turn during the rotation of the turntable 2, the corresponding curtain sheets 4 are opened to the maximum extent in turn and then closed again until they are completely closed.

The resulting effects are: the whole blind mat is opened by different areas sequentially according to the corresponding sequence, and is just like waves. Thus, as long as the rotation angle of the turntable 2 is controlled, there is always one direction corresponding to a certain area of the blind mat, thereby achieving independently controllable opening and closing of a certain height area. For example, when indoor personnel need to open the middle part of the blind mat independently and close other areas, only the connecting end 3 of the middle part needs to rotate to the highest point.

Aiming at the specific structure of the blind mat, two application scenes of indoor use and outdoor use exist. In this embodiment, the scheme of the indoor blind is described first:

referring to fig. 3 in detail, preferably, the curtain pieces 4 are connected in series by the ladder cord 6, the tail of the curtain piece 4 is provided with a receiving perforation, the pull cord 7 passes through the receiving perforation of all curtain pieces 4, the bottom end of the pull cord 7 is connected with the curtain piece 4 at the bottommost, and the top end of the pull cord 7 is 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. In a normal state, all the curtain sheets 4 sag and close under the action of the dead weight of the front part.

Besides the above-mentioned partial opening lighting, the blind mat also has the function of completely storing and opening. When the winding drum 18 rotates, the pull rope 7 is wound, so that the curtain sheet 4 is pulled to be stored from the bottom upwards, and the whole blind mat is stored from the bottom upwards. The rotation of the winding drum 18 may be performed manually, typically by means of a bead chain or the like, which brings about the rotation of the winding drum 18, as in the prior art. The solution is generally applied to the indoor side of a glazing, or to the inside of a glass partition.

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

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

As a further preferred option, the traction element 5 is a steel wire, which extends below the traction head and has its bottom end connected to a second slider (not shown); two sides of the blind mat are provided with second guide rails 12, and the second sliding blocks are in sliding connection with the second guide rails 12.

When the traction element 5 is a steel wire, a fixed pulley is also provided on the top of the upright in the drawing of the description to assist in guiding it, but this is not a necessary technical feature.

The steel wire is used as the traction piece 5, so that the occupied space of the traction piece 5 can be greatly reduced, each curtain piece 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 wind and tie. Therefore, the bottom end of the traction piece 5 made of each steel wire is connected with a second sliding block, which is a structural scheme convenient for wire arrangement. Moreover, the bottom end positions of all the traction members 5 are staggered in height, so that the second sliding blocks are also staggered in height, and all the second sliding blocks can be accommodated by only one second guide rail 12.

Preferably, the device also comprises a top beam 9 and a stand column 8; the upright posts 8 are fixedly arranged on two sides, and the top beams 9 are fixed on the tops between the upright posts 8; the rotating shaft 1 is arranged on the top beam 9, and the top end of the curtain is connected with the top beam 9; the traction members 5 are arranged to extend along the uprights 8 on both sides. The second guide rail 12, the second slider, and other components located on both sides of the blind mat may be stored in the pillar 8 to be shielded.

In order to improve the automation degree, more preferably, 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 turntable 2 to rotate. When indoor personnel need to control the blind mat to be opened 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 response to the shutter mat being stored, it is preferable that the turntable 2 and the winding drum 18 are coaxially connected to the rotation shaft 1 by transmission, and clutches (not shown) are provided between the turntable 2 and the rotation shaft 1 and between the winding drum 18 and the rotation shaft 1, respectively. In particular, the partial opening and the complete storage of the blind mat are two completely independent actions, the two completely independent actions cannot be performed synchronously, one motor can be saved by adopting clutch control, and the manufacturing cost is reduced.

As a sub-alternative, of course, as shown in fig. 3, the winding drum 18 is connected with a housing motor 11 in a driving manner, and the housing motor 11 alone drives the winding drum 18 to rotate. The dual motor drive scheme is more costly but is relatively simple to maintain.

Example two

The only difference between this embodiment and the first embodiment is that: the shutter mat of the embodiment adopts the scheme of an outdoor sunshade curtain, and focuses on the performances of strength, wind resistance and the like.

Referring to fig. 4 to 7, more specifically, the curtain sheet 4 is preferably connected in series by a scissors assembly 13 located at both sides of the blind mat; the scissors assembly 13 consists of scissors rods, the scissors rods are mutually hinged in the middle to form scissors units, and the end parts of the scissors units are connected in series in a head-to-tail hinged mode to form the scissors assembly 13; the bottom end of the scissor assembly 13 is connected with a stay cord 7, and the top end of the stay cord 7 is connected with a winding drum 18; the two sides of the blind mat are provided with first guide rails 14, and the crossing point of the scissors assembly 13 is provided with a first sliding block (not shown in the figure) which is in sliding connection with the first guide rails 14; the tail parts of the two ends of the curtain sheet 4 are hinged with the crossing points of the scissor assemblies 13, so that the curtain sheet 4 can swing around the crossing points of the scissor assemblies 13; the two ends of the curtain sheet 4 are also provided with supporting terminals 15, so that the curtain sheet 4 is erected on the corresponding scissor rods under the action of dead weight by the supporting terminals 15.

Unlike the indoor solution, the curtain sheet 4 in this embodiment can be made of a larger and stronger material. And the storage structure is also different from an indoor scheme, and a scissors fork structure is adopted. When the pull rope 7 is put down, the scissor assembly 13 can be stretched downwards, and the first sliding block is matched with the first guide rail 14 in the whole process, so that the wind resistance is high. When the pull rope 7 is retracted, the scissor assembly 13 is retracted upwards, and the supporting terminal 15 is supported by the scissor rod, so that the curtain sheet 4 is automatically opened and avoided in the retraction process, and the curtain sheet 4 is not blocked mutually.

When the control part is opened, as in the embodiment, the control turntable 2 is rotated, and the corresponding curtain sheet 4 is pulled to be opened by the traction piece 5, see fig. 7 in detail. During partial opening, the support terminal 15 may come off the scissor lever.

Preferably, the surface of the tail part of the curtain sheet 4 is provided with a concave 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 closed, 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 driving system automation scheme, are the same as those in the first embodiment, and will not be described herein.

According to the controllable sun-shading blind provided by the invention, the whole blind mat can be independently opened in different areas along with different rotation angles of the rotary table 2 through traction control of the special rotary table 2, so that the opening of the blind mat in different height areas can be independently controlled by only adjusting the angle of the rotary table 2. And the structure is simple, and the debugging is convenient. The traction member 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, the indoor scheme is light, and the cost is low; the outdoor scheme has high strength, wind resistance and rain resistance. And has an automated motorized solution.

The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
