Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention and the accompanying drawings are combined together to clearly and completely describe the technical solutions in the embodiments of the present invention. It should be noted that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Referring to fig. 1 to 5, an embodiment of the present invention provides a safety sunshade curtain, which includes a top bracket 1, a guide rail 2, a curtain mat 3, a driving system and a trigger switch 4; the guide rails 2 are vertically arranged on two sides, and the top support 1 is fixedly arranged on the top between the guide rails 2; the driving system is arranged on the top beam; the curtain mat 3 which can be stored upwards is in transmission connection with a driving system, and two sides of the curtain mat 3 are in sliding connection with the guide rails 2; the trigger switch 4 is fixed behind the guide rail 2 and is in transmission connection with the driving system;

the driving system comprises a motor 5, a synchronous shaft 6, a linkage gear 7, a winding shaft 8, a winding gear 9 and a clockwork spring 10; the motor 5 is in transmission connection with the synchronizing shaft 6, and two ends of the synchronizing shaft 6 movably connected to the top bracket 1 are respectively in transmission connection with a linkage gear 7; the winding shaft 8 is rotationally connected with the top bracket 1 and is in transmission connection with the curtain 3, the winding gear 9 is in transmission connection with two ends of the winding shaft 8, and the linkage gear 7 is in meshing transmission with the winding gear 9 when the synchronous shaft 6 approaches to the winding shaft 8; the clockwork spring 10 is arranged between the winding shaft 8 and the top bracket 1, so that the winding shaft 8 has the tendency of driving the curtain mat 3 to be accommodated;

the trigger switch 4 comprises a trigger member 19, a switch base 18 and a traction steel wire 11; the switch base 18 is fixedly arranged at the rear part of the guide rail 2; the trigger member 19 is movably connected to the switch base 18, and a trigger terminal 20 is fixedly and convexly arranged on the trigger member 19; the trigger member 19 is in transmission connection with the synchronizing shaft 6 through the traction steel wire 11 to drive the synchronizing shaft 6 to move.

The utility model has the biggest characteristic that the curtain mat 3 can be folded up at once whenever indoor personnel open the window. On one hand, the curtain 3 and the driving system are protected, and the curtain 3 is prevented from being continuously closed and colliding with the window after the window is opened; on the other hand, when the curtain 3 is completely closed, the curtain 3 can be completely retracted as long as the window is opened, and rescue can be helped when an emergency happens.

The specific working principle is as follows:

referring to fig. 1 to 3, when the window is closed, the window frame acts on the trigger switch 4, specifically, the trigger terminal 20, and the trigger member 19 is driven by the window frame via the trigger terminal 20 to move in the window closing direction, pulling the pull wire 11. The traction steel wire 11 which is pulled can drive the synchronizing shaft 6 to move towards the winding shaft 8, the linkage gear 7 can be in meshed transmission with the winding gear 9, the power of the motor 5 is transmitted to the winding shaft 8, and the winding shaft 8 is in a gear engaging state. In the 'gear engaging' state, the motor 5 rotates forward and backward to control the curtain 3 to close or retract at will, and the function is completely equivalent to that of a common sunshade curtain product. In the closing process of the curtain mat 3, the winding shaft 8 can overcome the elasticity of the clockwork spring 10 to rotate, which is equivalent to the process of winding the clockwork spring 10; in the process of folding the curtain 3, the winding shaft 8 rotates in the direction of the spring force of the spring 10, which corresponds to the process of releasing the spring 10.

When the window is opened at any time and the trigger terminal 20 is no longer pressed by the jamb, the pull wire 11 is released. At this time, the synchronizing shaft 6 is separated from the winding shaft 8, so that the interlocking gear 7 is disengaged from the winding gear 9, and the power of the motor 5 cannot be transmitted to the winding shaft 8, and the state is "neutral". At this time, the elastic force of the spring 10 will drive the winding shaft 8 to rotate, thereby driving the curtain 3 to retract rapidly.

It should be noted that the specific structure of the curtain 3 is irrelevant to the technical point of the present invention. No matter what kind of structure is adopted by the curtain mat 3, the utility model can be applied to the middle as long as the curtain mat can be folded upwards.

Detailed description of the drawings with reference to fig. 1 to 2, the drive system preferably also comprises a mobile carriage 12; the motor 5 is fixedly arranged on the movable support 12, and the synchronizing shaft 6 is rotationally connected to the movable support 12 and is in transmission connection with the motor 5; the movable bracket 12 is hinged on the top bracket 1 and drives the synchronizing shaft 6 to swing to be close to or far away from the winding shaft 8; the top end of the traction steel wire 11 is connected with a movable bracket 12.

The movable action of the synchronizing shaft 6 is realized by the movable bracket 12, the synchronizing shaft 6 keeps a transmission connection relation with the motor 5 all the time, the design is more scientific, and the whole transmission structure is simplified. The movable support 12 realizes the movement of the synchronizing shaft 6 in a swinging mode, and is favorable for ensuring the stability of the movement process. Theoretically, as long as the tooth heights of the linkage gear 7 and the winding gear 9 are small, the moving amplitude of the synchronizing shaft 6 only needs to be small to realize engagement and disengagement.

Further preferably, a first spring (not shown) is provided between the movable bracket 12 and the top bracket 1 to urge the synchronizing shaft 6 away from the winding shaft 8. The first spring between the movable bracket 12 and the top bracket 1 is not necessarily installed, and by optimizing the installation orientation of the movable bracket 12, the tendency of the synchronizing shaft 6 to be away from the winding shaft 8 can be realized by the dead weight of the motor 5, the synchronizing shaft 6 and the movable bracket 12. However, the first spring can improve the reliability of the movement of the mechanism and can also reduce the limitation of the layout of the movable bracket 12.

Since the linkage gear 7 and the winding gear 9 always have a tendency of disengaging from each other in the transmission process, in the process of engaging the linkage gear and the winding gear to be in gear, enough force is required to tightly push the movable bracket 12 to stabilize the synchronizing shaft 6. To address this need, there are two approaches:

referring to fig. 1 to 2 in detail, as a first preferred mode, the movable bracket 12 is provided with a connection terminal 13 extending from the synchronizing shaft 6, and the top end of the traction wire 11 is connected to the connection terminal 13. The connecting terminal 13 makes the overall mechanical structure of the movable support 12 a labor-saving lever, and the traction wire 11 only needs to provide a small force to keep the synchronizing shaft 6 stable.

As shown in detail in fig. 3, as another preferred mode, a self-locking mechanism 14 is arranged between the movable bracket 12 and the top bracket 1; the self-locking mechanism 14 comprises a swinging rod 15, a connecting rod 16 and a shifting rod 17; one end of the swing rod 15 is connected with the movable bracket 12, and the other end is hinged with the top bracket 1; one end of a deflector rod 17 is hinged with the top bracket 1 and is arranged in a crossed way with the swinging rod 15, and the other end of the deflector rod 17 is connected with the traction steel wire 11; two ends of the connecting rod 16 are hinged to the middle of the swinging rod 15 and the middle of the deflector rod 17; a third spring (not shown) is provided between the shift lever 17 and the top bracket 1, so that the shift lever 17 has a tendency to release the oscillating lever 15. When the pulling steel wire 11 pulls the shift lever 17, the connecting rod 16 can drive the swing rod 15 to swing, and the movable support 12 is pushed to swing towards the winding shaft 8. When the linkage gear 7 is meshed with the winding gear 9, the connecting rod 16 and the shifting rod 17 of the self-locking mechanism 14 move to parallel positions, and the swinging rod 15 is pushed to be dead no matter how large force is applied to break away, so that self-locking is realized. The traction wire 11 thus only needs to provide a small force to keep the synchronizing shaft 6 stable. The self-locking principle can refer to the self-locking clamp in the prior art.

The trigger switch 4 has two embodiments. Referring to fig. 4, in the present embodiment, preferably, the triggering member 19 is slidably connected to the switch base 18, and the bottom end of the traction wire 11 is connected to the triggering member 19. The sliding type trigger structure is simple in structure and easy to produce, manufacture and install. However, the sliding travel of the triggering element 19 is equal to the pulling travel of the traction wire 11, which cannot be adjusted.

Further preferably, a second spring (not shown) is provided between the trigger member 19 and the switch base 18 to make the trigger member 19 tend to release the traction wire 11, thereby increasing the response speed of the trigger switch 4 during the windowing process.

Furthermore, a fixed pulley for changing the trend of the traction steel wire 11 is preferably arranged on the guide rail 2 and the top bracket 1, and the traction steel wire 11 is wound on the fixed pulley so as to reasonably plan the trend of the traction steel wire 11.

Referring to fig. 6, as the response speed is usually faster as long as the spring 10 acts to retract the curtain 3, the curtain 3 may be damaged due to too fast action. In order to solve this problem, it is preferable that the guide rail 2 has a buffer strip 22 at the top thereof which gradually converges inward from the bottom to the top, and buffer heads 23 having a wide bottom and a narrow top are provided at the bottom ends of both sides of the curtain 3. When the curtain 3 is rapidly retracted by the action of the springs 10 and reaches the top end of the guide rail 2, the cushion tape 22 exerts a frictional damping cushion action on the cushion head 23, and the speed thereof is reduced. The buffer belt 22 and the buffer head 23 are designed in a progressive manner, and the resistance to the movement of the buffer belt and the buffer head is increased towards the top end of the guide rail 2 until the buffer belt and the buffer head stop. When the curtain 3 is put down, the damping effect is gradually weakened, and the putting-down and closing actions of the curtain 3 are not hindered.

Example two

The only difference between this embodiment and the first embodiment is the specific structure of the trigger switch 4.

Referring to fig. 5, specifically, preferably, the triggering member 19 is rotatably connected to the switch base 18, and the triggering member 19 is provided with adjusting holes 21 radially arranged along a rotation center, and a bottom end of the traction wire 11 is connected to the adjusting hole 21 at any position.

Although the triggering member 19 is more complex when swinging and hinging, the triggering member has different adjusting holes 21 according to the size of the rotating radius, thereby forming strokes with different lengths for the traction steel wire 11 and facilitating the adjustment of the action of the matching driving system.

Other technical features of this embodiment, such as the structure of the driving system and the arrangement of the buffer zone 22, are completely the same as those of the first embodiment, and are not described herein again.

The utility model provides a pair of safe sunshade curtain to clockwork spring 10 is power, in any time, as long as open the window, curtain mat 3 will upwards pack up automatically, prevents to hit the window at 3 closed in-process of curtain mat, can open the demand that window and curtain mat 3 fleed at any time when dangerous situations such as fire control appear still having satisfied. The lifting and the opening of the daily curtain 3 can be controlled by the motor 5, and the use is the same as that of a normal sunshade curtain. The operation principle is not electrically controlled, but is purely mechanical, and the operation principle can still function even under the condition of extreme power failure, so that the operation principle has extremely high reliability. Trigger switch 4 can install in the outside of all kinds of windows, takes place the combined action with the window, and the commonality is strong. And has a top buffer structure to prevent the curtain 3 from being damaged in the process of folding.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
