[0002] The sunshade curtain is a curtain cloth for blocking sunlight and has a wide range of application scenarios in life, such as cars, interior decoration, and greenhouse sheds.

[0003] In a greenhouse shed, the sunshade curtain is used to cover part of the sunlight from the outside when the intensity of the sunlight is too high, so that the intensity of the sunlight in the greenhouse is maintained at a suitable intensity for plant growth. When the intensity of the outside light decreases, the sunshade curtain needs to be retracted so that the sunlight from the outside can enter the greenhouse to meet the needs of plant growth.

[0004] In the use process of the sunshade curtain in the greenhouse, the sunshade curtain is pulled by a guide mechanism such as a guide rope and is driven by a driving mechanism to realize the use of the sunshade curtain. When the sunshade curtain is retracted, the traction mechanism and the sunshade curtain are retracted together. Therefore, when the sunshade curtain needs to be replaced due to damage, the sunshade curtain needs to be separated from the traction mechanism first, so that the sunshade curtain can be replaced. The replacement process is troublesome and inconvenient for the replacement of the sunshade curtain. CONTENT OF THE INVENTION

[0012] By adopting the technical scheme, the guide rope drives the first clamping block to move, and the second clamping block and the first clamping block cooperate to clamp the sunshade curtain, so that the effect that the sunshade curtain moves with the traction rope is realized, and the control on the movement state of the sunshade curtain is completed.

[0013] Optionally, a cooperation groove is formed in one side of the first clamping block facing the second clamping block, and a cooperation protrusion is arranged on one side of the second clamping block facing the first clamping block.

[0016] By adopting the technical scheme, the magnetic attraction between the first magnet and the second magnet further reduces the probability that the first clamping block and the second clamping block slide towards each other, and improves the clamping ability of the first clamping block and the second clamping block on the sunshade curtain.

[0017] Optionally, the clamping transmission mechanism comprises a clamping block placing frame, the clamping block placing frame is connected with a rotating motor, a plurality of placing holes are arranged around the clamping block placing frame, and the second clamping block is installed in the placing hole.

[0018] By adopting the above technical scheme, the clamping block placing frame provides a placing space for the second clamping block, the rotating motor drives the clamping block placing frame to rotate synchronously with the second winding roller, so that the second clamping block can rotate synchronously with the first clamping block, and the cooperation of the first clamping block and the second clamping block is facilitated.

[0021] Optionally, the locking piece comprises a locking rod, a reset spring and an abutting rod, the hole wall of the placing hole is provided with a locking sliding hole, the locking rod slides in the locking sliding hole, one side of the clamping placing frame facing the first clamping block is provided with an abutting hole, the abutting rod slides in the abutting hole, the abutting rod is used for driving the locking rod to move away from the placing hole, and the reset spring is located in the locking sliding hole and connected to one side of the locking rod away from the placing hole.

[0028] By adopting the above technical scheme, the first magnet is arranged as an electromagnet, which can generate magnetism by being electrified when the first clamping block and the second clamping block clamp the sunshade curtain, thereby attracting the second magnet, facilitating the cooperation of the first clamping block and the second clamping block. When the sunshade curtain is retracted, the first magnet can be de-energized or generate reverse magnetic force by passing through a reverse current, thereby facilitating the separation of the first clamping block and the second clamping block, and facilitating the retraction of the sunshade curtain by the first retraction roller.

[0029] Compared with the prior art, the present application has at least one of the following beneficial technical effects:

[0030] 1. When the sunshade curtain is used, the drive motor drives the retraction baffle and the second retraction roller to rotate. The rotation of the retraction baffle drives the first retraction roller to rotate, so that the sunshade curtain starts to be released. The rotation of the second retraction roller drives the guide rope to move, the guide rope pulls the clamping assembly to move, and the clamping assembly clamps the sunshade curtain, thereby realizing the sun-shading function of the sunshade curtain. After the sunshade curtain is damaged, the drive motor reverses to drive the retraction baffle and the first retraction roller to reverse. The retraction baffle drives the first retraction roller to rotate to retract the sunshade curtain. The second retraction roller rotates to retract the guide rope and the clamping assembly. When the sunshade curtain is replaced, only the first retraction roller and the retraction baffle are connected to the sunshade curtain to be removed from the retraction seat. The sunshade curtain on the first retraction roller is replaced, and the first retraction roller is reconnected with the retraction seat, so that the replacement of the sunshade curtain can be realized. Alternatively, a new sunshade curtain, a first retraction roller and a retraction baffle can be directly used to realize the replacement of the sunshade curtain, thereby facilitating the replacement of the sunshade curtain.

[0031] 2. The locking member can keep the second clamping block in the mounting hole when the second clamping block is not connected with the first clamping block. When the first clamping block and the second clamping block are in contact, the trigger block is in contact with the locking member, so that the locking member can be separated from the second clamping block, thereby facilitating the clamping of the sunshade curtain by the second clamping block and the first clamping block.

[0032] 3. The first magnet and the second magnet are embedded in the first clamping block and the second clamping block, thereby facilitating the cooperation and connection between the first clamping block and the second clamping block. The first magnet is arranged as an electromagnet, which is electrified when the first clamping block and the second clamping block are connected. The first magnet attracts the second magnet, thereby facilitating the connection of the first clamping block and the second clamping block. When the first clamping block and the second clamping block are separated, the first magnet is de-energized or passes through a reverse current, thereby facilitating the separation of the first clamping block and the second clamping block.

The drive motor 21 is connected to the retractor baffle 13 and the second retractor roller 22 through gears. The guide rope 23 is looped and connected end to end. One end of the guide rope 23 is sleeved on the second retractor roller 22, and the other end of the guide rope 23 is sleeved on the rotary rod 25. The clamping assembly 24 is connected to the guide rope 23 and clamps or releases the sunshade curtain as the guide rope 23 moves.

[0041] When the sunshade curtain is shading, the driving motor 21 drives the rolling baffle 13 and the second rolling roller 22 to rotate, the rolling baffle 13 drives the first rolling roller 11 and the second rolling roller 22 to rotate synchronously, so that the sunshade curtain on the first rolling roller 11 is released and clamped by the clamping assembly 24 connected by the guide rope 23 on the second rolling roller 22, the sunshade curtain is laid between the second rolling roller 22 and the rotary rod 25 along with the movement of the guide rope 23, and the shading effect is realized. When the sunshade curtain needs to be replaced due to damage, the driving motor 21 can be reversed, the sunshade curtain is separated from the clamping assembly 24 and is collected to the outside of the first rolling roller 11, the first rolling roller 11 is separated from the rolling baffle 13 and the rolling abutment 12, a new sunshade curtain is replaced with the damaged sunshade curtain, and the first rolling roller 11 is reinstalled on the rolling abutment 12, so that the replacement of the sunshade curtain is completed, or a new sunshade curtain, the first rolling roller 11 and the rolling baffle 13 are directly used, and the replacement of the sunshade curtain can also be realized, finally, the replacement of the sunshade curtain is facilitated.

[0042] With reference to Figure 1 and Figure 2 , the clamping assembly 24 comprises a first clamping block 241, a second clamping block 242 and a clamping transmission mechanism 243, the first clamping block 241 is connected with the guide rope 23, the second clamping block 242 is connected with the clamping transmission mechanism 243, the second clamping block 242 cooperates with the first clamping block 241 to clamp the sunshade curtain, and the clamping transmission mechanism 243 is arranged at intervals of the second rolling roller 22 and rotates synchronously with the second rolling roller 22.

[0043] The first clamping block 241 and the second clamping block 242 jointly clamp the sunshade curtain and drive the sunshade curtain to move along with the movement of the guide rope 23 under the traction of the guide rope 23, and finally the sunshade curtain is laid between the second rolling roller 22 and the rotary rod 25, so that the shading function of the sunshade curtain is realized.

[0044] With reference to Figure 1 and Figure 2 , a matching groove 2411 is formed on the side of the first clamping block 241 facing the second clamping block 242, a matching protrusion 2421 is arranged on the side of the second clamping block 242 facing the first clamping block 241, a friction layer is arranged on the inner wall of the matching groove 2411 and the outer wall of the matching protrusion 2421, a first magnet is embedded in the first clamping block 241 by an injection molding process, a second magnet is embedded in the second clamping block 242 by an injection molding process, the first magnet is arranged as an electromagnet, and the first magnet and the second magnet attract each other when the first clamping block 241 is connected with the second clamping block 242.

By arranging the first magnet as an electromagnet, when the first clamping block 241 and the second clamping block 242 clamp the sunshade curtain, the first magnet is electrified and attracts the second magnet, enhances the connection tightness between the first clamping block 241 and the second clamping block 242, and the first clamping block 241 and the second clamping block 242 can better clamp the sunshade curtain. When the sunshade curtain is recycled, the first magnet can be de-energized or pass a reverse current, so that the first clamping block 241 and the second clamping block 242 can be separated from each other, and the sunshade curtain is recycled to the outside of the first winding roller 11.

[0046] With reference to Figure 1 The clamping transmission mechanism 243 comprises a clamping block placing frame 2431 and a rotating motor 2432, the clamping block placing frame 2431 is coaxially connected with the output shaft of the rotating motor 2432, and the rotating motor 2432 is synchronously rotated with the driving motor 21.

[0047] The clamping transmission mechanism 243 drives the clamping block placing frame 2431 to synchronously rotate with the second winding roller 22 by the rotating motor 2432, so that the second clamping block 242 can be matched with the first clamping block 241, thereby realizing the clamping of the sunshade curtain. When the sunshade curtain is recycled, the rotating motor 2432 cooperates with the driving motor 21, so that the second clamping block 242 can be placed in the placing hole 24311, thereby realizing the recycling of the second clamping block 242.

[0048] With reference to Figure 2 , Figure 3 and Figure 4The locking piece 244 in the placement hole 24311 can lock the second clamping block 242 in the placement hole 24311 when the second clamping block 242 is not matched with the first clamping block 241, so as to reduce the probability that the second clamping block 242 is separated from the placement hole 24311. When the first clamping block 241 is matched with the second clamping block 242, the trigger block 245 is abutted with the abutment rod 2443 to drive the abutment rod 2443 to slide in the abutment hole 24313. The abutment rod 2443 is connected with the locking rod 2441 through the abutment slope, so as to drive the locking rod 2441 to move away from the placement hole 24311, thereby separating the locking rod 2441 from the second clamping block 242. The second clamping block 242 is matched with the first clamping block 241 to clamp the sunshade curtain.

[0049] The locking piece 244 in the placement hole 24311 can lock the second clamping block 242 in the placement hole 24311 when the second clamping block 242 is not matched with the first clamping block 241, so as to reduce the probability that the second clamping block 242 is separated from the placement hole 24311.

The abutment rod 2443 is connected with the locking rod 2441 through the abutment slope, so as to drive the locking rod 2441 to move away from the placement hole 24311, thereby separating the locking rod 2441 from the second clamping block 242. The second clamping block 242 is matched with the first clamping block 241 to clamp the sunshade curtain.

[0050] With reference to Figure 1 The distance between the adjacent first clamping block 241 supports connected by the guide rope 23 increases or decreases along the moving direction of the sunshade curtain. When the sunshade curtain is retracted, the second clamping block 242 can be retracted into the adjacent placement holes 24311 in the clamping block placement frame 2431 in sequence, so as to facilitate the retraction of the second clamping block 242.

[0051] The implementation principle of the sunshade curtain control device is as follows: when the sunshade curtain is shading, the driving motor 21 drives the winding baffle 13 and the second winding roller 22 to rotate, the winding baffle 13 drives the first winding roller 11 to rotate, so that the first winding roller 11 and the second winding roller 22 rotate synchronously, the first winding roller 11 releases the sunshade curtain and the clamping assembly 24 driven by the traction rope clamps, the sunshade curtain is laid between the second winding roller 22 and the rotary rod 25, and the shading work of the sunshade curtain is completed.
