The recyclable electric blind control system 100 provided in this embodiment can drive the transmission assembly 30 by the driving motor, and then control the opening, closing and releasing of the blind 20 by the transmission assembly 30 through the linkage assembly 40, and the following detailed description is given by combining the control method of the recyclable electric blind control system 100 provided in this embodiment:

taking the fully lowered closed state of the blind 20 as shown in fig. 2 as an initial state, all the blinds 21 are in the longitudinally closed state, and the linkage seat 34 is located at the first position L1 as shown in fig. 7. The control method of the recyclable electric blind control system 100 is specifically as follows:

as shown in fig. 7 and 8, step 1: the driving motor drives the driving wheel 31 to rotate in a first direction D1 as shown in FIG. 7, and the synchronous belt 33 is driven to rotate in the first direction D1 under the assistance of the driven wheel 32, so that the linkage seat 34 longitudinally moves from a first position L1 to a second position L2;

the linkage seat 34 drives the driving connecting rod 41 to push the first swinging connecting rod 42a to rotate from the longitudinal direction to the transverse direction, and synchronously drives the first shutter 21a to turn from the longitudinal closing state to the transverse opening state;

under the linkage transmission of the folding connecting rods 43, the swinging connecting rods 42 synchronously drive the connected shutters 21 to turn from a longitudinal closing state to a transverse opening state;

until the linkage mount 34 reaches the second position L2, each swinging link 42 turns to the lateral direction, and each shutter 21 turns to the lateral open state, at which time the shutter curtain 20 assumes the lowered open state as shown in fig. 3.

As shown in fig. 8 and 9, step 2: the driving motor drives the driving wheel 31 to continuously rotate in the first direction D1, and the synchronous belt 33 is driven to rotate in the first direction D1 under the assistance of the driven wheel 32, and the linkage seat 34 starts to longitudinally move upwards from the second position L2;

the linkage seat 34 pushes the first swing link rod 42a to move upwards, the first swing link rod 42a is upwards close to the adjacent swing link rod 42 above the first swing link rod, the folding link rod 43 between the first swing link rod 42a and the adjacent swing link rod 42 above the first swing link rod is inwards folded until the first swing link rod 42a is folded with the adjacent swing link rod 42 above the first swing link rod and then moves upwards continuously;

and so on, and then each swinging connecting rod 42 is pushed by the linkage seat 34 to move up and down one by one layer, when two adjacent swinging connecting rods 42 are close to each other, the folding connecting rod 43 between the two swinging connecting rods is folded inwards;

each swinging connecting rod 42 drives the respective connected blinds 21 to synchronously move up and down one by one in a layer-by-layer manner, so that the blinds 20 are recovered from bottom to top;

when the linkage seat 34 pushes the folding link 42 up all the way together, the linkage seat 34 reaches the third position L3; at this time, as shown in fig. 4, all the blinds 21 are stacked on the upper end of the frame 10, and the blinds 20 are completely recovered.

As shown in fig. 8 and 9, step 3: the driving motor drives the driving wheel 31 to rotate in a second direction D2 opposite to the first direction D1 as shown in FIG. 9, and the synchronous belt 33 is driven to rotate in the second direction D2 under the assistance of the driven wheel 32, so that the linkage seat 34 starts to longitudinally move downwards from the third position L3;

under the assistance of the gravity of each swinging connecting rod 42, each swinging connecting rod 42 is separated layer by layer from top to bottom and moves downwards, when two adjacent swinging connecting rods 42 are far away from each other, the folding connecting rod 43 between the two swinging connecting rods is unfolded until the two swinging connecting rods are unfolded to the limit length, and the two adjacent swinging connecting rods 42 return to the initial distance between the two swinging connecting rods;

under the assistance of the gravity of each shutter 21, each shutter 21 is synchronously separated from top to bottom one by one along with the swing connecting rod 42 connected with each shutter until the shutter returns to the initial position, so that the shutter curtain 20 is lowered from top to bottom;

when the linkage mount 34 is returned to the second position L2, all of the folding links 43 are unfolded, all of the swinging links 42 and the louvers 21 are returned to their respective initial positions, and the blind 20 is fully lowered back to the lowered open state shown in fig. 3.

As shown in fig. 7 and 8, step 4: the driving motor drives the driving wheel 31 to rotate in the second direction D2, and the synchronous belt 33 is driven to rotate in the second direction D2 under the assistance of the driven wheel 32, so that the linkage seat 34 longitudinally moves from the second position L2 to the first position L1;

the linkage seat 34 drives the driving connecting rod 41 to pull the first swinging connecting rod 42a to rotate from transverse direction to longitudinal direction, and synchronously drives the first shutter 21a to turn from a transverse opening state to a longitudinal closing state;

under the linkage transmission of the folding connecting rods 43, the swinging connecting rods 42 synchronously drive the connected shutters 21 to turn from the transverse opening state to the longitudinal closing state;

the linkage seat 34 comes to the first position L1, the swing links 42 are turned to the longitudinal direction, the shutters 21 are turned to the longitudinal closing state, and the shutter curtain 20 is restored to the lowered closing state of the initial state as shown in fig. 2.

In the present embodiment, the first position L1 is lowest, near the bottom end of the side frame 13, the third position L3 is highest, near the top end of the side frame 13, and the second position L2 is above the first position L1, and the longitudinal distance between the second position L1 and the first position L1 is related to the rotation radius of the swing link 42.

In step 1 and step 4, the driving motor may stop driving halfway, so that the linkage seat 34 stays at any position between the first position L1 and the second position L2, and the blind 20 is in a half-open and half-closed state, so as to adjust the brightness of the light incident through the blind 20. When the driving motor is restarted, the driving motor can be rotated in the first direction D1 or the second direction D2 again, so that the linkage seat 34 can start to move from the stop position to the first position L1 or the second position L2 again, and the shutter curtain 20 can be opened or closed.

Similarly, in step 2 and step 3, the driving motor may be stopped halfway, so that the linkage seat 34 stays at any position between the second position L2 and the third position L3, and the blind 20 is in the semi-recovery state. When the driving motor is restarted, the driving motor can be rotated in the first direction D1 or the second direction D2 again, so that the linkage seat 34 can be moved from the stop position to the second position L2 or the third position L3 again, and the shutter curtain 20 can be recovered or lowered. And further flexibly select and control the opening and closing modes of the blind curtain 20.

In step 2 and step 3, since the end of the shutter 21 is connected to the swinging connecting rod 42 through the turning shaft seat 22, when the shutter 21 and the swinging connecting rod 42 are recovered and lowered, the turning shaft seat 22 is sequentially moved up from bottom to top or is sequentially moved down from top to bottom in the longitudinal opening F, so that a stable guiding effect of the first layer is provided, that is, the vertical movement of the swinging connecting rod 42 and the shutter 21 plays a stable guiding role.

In steps 1 to 4, since the linkage seat 34 is connected to the sliding trolley 50, when the synchronous belt 33 drives the linkage seat 34 to longitudinally move among the first position L1, the second position L2 and the third position L3, the sliding trolley 50 synchronously longitudinally slides along the track groove, so that a stable guiding effect of the second level is provided, namely stable operation when the synchronous belt 33 drives the linkage seat 34 is maintained.

Particularly when the recyclable electric blind control system 100 is applied to a use scene of the awning 200 with blind walls provided in this embodiment, or in blind walls with higher heights such as building walls, the self weight of the blind 21 is larger, and the stability requirement for turning the blind is higher; and the moving distance is longer when the shutter curtain 20 is recovered or lowered, the synchronous belt 33 is easy to shake, so that the movement of the linkage seat 34 is unstable, and meanwhile, the length of the linkage assembly 40 is longer, and the requirement for stable matching between the transmission assembly 30 and the linkage assembly 40 is higher. At this time, the advantages of the recyclable electric blind control system 100 provided in this embodiment are more remarkable than those of the prior art, and the recyclable electric blind control system has stronger stability under the smart cooperation among the side frame 13, the transmission assembly 30 and the linkage assembly 40.

Further, compared with the prior art, the transmission assembly 30 provided in this embodiment has the key that the arrangement of the linkage seat 34 and the cooperation of the linkage seat with the driving link 41 and the first swinging link 42a in the linkage assembly 40 form a transmission linkage joint, and the stable guiding guarantee of the two layers is combined, so that the transmission operation of the blind 20 can be completed by passing through the synchronous belt 33 of the side frame 13 up and down.

In addition, the frame 10 of the control system 100 of the retractable electric blind provided in this embodiment is not just a supporting member, but the longitudinal opening F cooperates with the tilting shaft seat 22 to perform a stable guiding function, in addition to the above-mentioned structure of the rail groove 14 cooperating with the rail car 50.

As shown in fig. 12, the turning shaft seat 22 is laterally penetrated and provided with a shaft hole H, and the end of the shutter 21 is convexly provided with a connecting column E, wherein the connecting column E comprises a shaft joint portion E1 matched with the shaft hole H, and a limiting portion E2 at the front end of the shaft joint portion E1. The shaft joint part E1 is inserted into the shaft hole H of the turnover shaft seat 22 so that the shutter 21 and the turnover shaft seat 22 form turnover shaft joint; the limiting portion E2 is inserted into the corresponding swinging link 42, so that the shutter 21 and the swinging link 42 form a circumferentially limited connection.

Therefore, when the swinging connecting rod 42 drives the shutter 21 connected with the swinging connecting rod to turn over, the turning shaft seat 22 does not act, and when the swinging connecting rod 42 drives the shutter 21 to longitudinally move up and down, the turning shaft seat 22 longitudinally moves up and down along the longitudinal opening F, so that the stable guiding effect of the first layer is realized.

As shown in fig. 11, cylindrical reinforcing ribs F1 extending longitudinally are disposed on two sides of the longitudinal opening F, protruding clamping strips F2 are disposed on the reinforcing ribs F1 along the length direction, and the reinforcing ribs F1 serve to strengthen the mechanical strength of the longitudinal opening F on one hand and form a shaft seat rail together with the clamping strips F2 for the longitudinal movement of the overturning shaft seat 22 on the other hand. Longitudinal clamping grooves F3 are concavely formed in two sides of the overturning shaft seat 22, the overturning shaft seat 22 is clamped in the longitudinal opening F, and clamping strips F2 are clamped in the clamping grooves F3, so that the overturning shaft seat 22 can longitudinally move up and down along a shaft seat track on the longitudinal opening F.

The two sides of the clamping groove F3 of the overturning shaft seat 22 further extend to the two sides to form an arc-shaped wrapping groove F4 matched with the outer peripheral surface of the reinforcing rib F1, the clamping groove F3 is clamped on the clamping strip F2, and the wrapping groove F4 wraps a part of the reinforcing rib F1 on the two sides of the clamping strip F2, so that the overturning shaft seat 22 is further ensured to stably move on a shaft seat track.

As shown in fig. 5, 7 and 8, the bottom end of the side frame 13 is fixedly provided with a shaft seat push rod 16, and the lower end of the shaft seat push rod 16 is fixed on the lower fixing frame G2 and extends upwards. When the shutter 21 is in the transversely opened state, the shutter curtain 20 is gradually lowered until the shutter curtain 20 is completely lowered, and the linkage seat 34 returns to the second position L2, the shaft seat push rod 16 abuts against the first overturning shaft seat 22a, so that the lowest position of the shutter curtain 20 is limited.

Further, when the linkage seat 34 moves longitudinally from the second position L2 to the first position L1, the linkage seat 34 drives the driving link 41 to pull the first swing link 42a to rotate longitudinally from the transverse direction, and the axle seat push rod 16 pushes against the first overturning axle seat 22a, so as to prevent the longitudinal position of the first swing link 42a from moving downwards, and serve as a lever fulcrum for the first swing link 42a to rotate longitudinally from the transverse direction.

As shown in fig. 8 to 10, the linkage seat 34 is provided with an inwardly extending lift lever 35, and when the linkage seat 34 is further moved longitudinally upward from the second position L2, the lift lever 35 lifts the first swing link 42a to move from bottom to top. At this time, the driving link 41 is pivotally connected to and supports one end of the first swing link 42a, the lifting lever 35 supports the other end of the first swing link 42a, and the driving link 41 and the lifting lever 35 lift the first swing link 42a substantially to the horizontal, so that the upper swing links 42 are stacked one by one with the first swing link 42a being bottomed along with the upward movement of the link seat 34, and each shutter 21 is ensured to be lifted up smoothly at the time of recovery.

As shown in fig. 13 in combination with fig. 7 to 9, two folding links 43 are pivotally connected between two adjacent swinging links 42, and each folding link 43 is pivotally connected to two longitudinally opposite ends of two swinging links 42 up and down, so that two folding links 43 pivotally connected between two adjacent swinging links 42 and two swinging links enclose one linkage unit 40a, and a series of linkage units 40a are connected in series to form a column of linkage assemblies 40 in the embodiment.

As shown in fig. 13, the folding link 43 includes a first strut 43a and a second strut 43b that are coupled to each other, and the second strut 43b is provided with a boss T at a coupling position of the two such that a folding angle R of less than 180 degrees and having an opening facing outward is formed between the first strut 43a and the second strut 43 b. In other embodiments, the boss T may be provided on the first strut 43 a.

When the longitudinal distance between two adjacent swinging connecting rods 42 is farthest, the folding angle R of the two folding connecting rods 43 between the two swinging connecting rods is largest, and the vertex distance is farthest; when the adjacent swing links 42 are close to each other, the folding angle R of the two folding links 43 therebetween becomes smaller gradually and the apex distance becomes closer gradually as the longitudinal distance shortens, thereby ensuring that both folding links 43 fold inwardly until the adjacent swing links 42 are overlapped with each other, and both folding links 43 fold inwardly between the adjacent swing links 42.

As shown in fig. 7 and 8, the top end of the linkage assembly 40 is provided with a brake rope 44 and an auxiliary spring 45, the upper ends of the brake rope 44 and the auxiliary spring 45 are fixedly connected to an upper fixing frame G1 at the upper end of the frame 10, the lower end of the brake rope 44 is connected to one end of the uppermost second swing link 42b, and the lower end of the auxiliary spring 45 is connected to the other end of the second swing link 42 b.

When the shutter 21 is in the laterally opened state, the brake cord 44 is tightened to assist the shutter 21 to remain in a substantially horizontal state, while the assist spring 45 is substantially relaxed; when the shutter 21 is in a longitudinally closed state, the brake cord 44 is relaxed, and the auxiliary spring 45 lengthens the power; the restoring force of the contraction of the assist spring 45 can assist the turning of the louver 45 when the louver 21 turns from the longitudinally closed state to the laterally open state.

As shown in fig. 6, the inner ring surface of the timing belt 33 is uniformly distributed with transmission racks C1, the outer peripheral surfaces of the driving wheel 31 and the driven wheel 32 are uniformly distributed with driving racks C2, and the driving racks C2 of the driving wheel 31 and the driven wheel 32 are meshed with the transmission racks C1 of the timing belt 33 to drive the timing belt 33 to rotate around the driving wheel 31 and the driven wheel 32.

The linkage seat 34 is clamped on the synchronous belt 33 through screws so as to be fixed with the synchronous belt, one side of the inner ring surface of the synchronous belt 33 clamped by the driving seat 34 is provided with a clamping rack (not shown in the figure) which is meshed with the transmission rack C1 in a direction, so that the fixed connection between the two is firmer, and when the driving seat 34 is driven by the synchronous belt 33 to longitudinally move up and down, the meshing between the transmission rack C1 and the clamping rack further plays a role of longitudinal limiting, so that the linkage seat 34 is prevented from falling off from the synchronous belt 33 under the action of the gravity of the heavy shutter 21.
