Examples

Referring to fig. 1 to 4, the present invention provides a novel sunshade curtain, which comprises a driving system 1, a top beam 2, a guide rail 3 and a curtain mat 4; wherein the curtain mat 4 comprises a plurality of scissor assemblies, a shade 5 and a bottom curtain 6; the shearing fork assembly consists of a plurality of shearing fork strips 14, every two of the shearing fork strips 14 are hinged in a crossing way, and the adjacent groups of the shearing fork strips 14 which are hinged in a crossing way are hinged at the end parts; the plurality of scissor assemblies are vertically, telescopically and transversely arranged, adjacent scissor assemblies are arranged in a staggered manner in the thickness direction, and the bottom ends of the scissor assemblies are hinged with the bottom curtain 6; the left end and the right end of the bottom curtain 6 are respectively provided with a sliding block 7, the sliding blocks 7 are in sliding connection with the guide rails 3 which are vertically fixed on the left side and the right side, and the sliding blocks 7 are in transmission connection with the driving system 1; the top beam 2 is fixedly and transversely arranged at the tops of the two guide rails 3, and the top end of the scissor assembly is hinged with the top beam 2; a gobo 5 of flexible material is mounted to each of the scissor bars 14 for closing movement between the gobos 5 when the scissor assemblies are extended downwardly.

The invention utilizes the characteristics of the scissors structure, and utilizes the driving system 1 to drive the bottom curtain 6 to ascend and descend for sliding, thereby enabling the scissors assembly to be folded or extended. During folding or stretching, the position is that the light-transmitting and air-permeable cavity surrounded by the scissors strips 14 is the largest, namely, the curtain mat 4 undergoes the increase-decrease of the cavity during the opening and closing process. Therefore, the opening and closing of the curtain 4 and the degree of lighting ventilation can be controlled by driving the raising and lowering of the bottom curtain 6. In this structure, the entire curtain 4 is interlocked, so that the state of the entire curtain 4 is changed synchronously, and the problem that the state of the bottom of the curtain 4 is different from that of the upper part of the curtain 4 does not occur.

In this structure, both the light shielding and the wind shielding require the closing of the light shielding sheet 5. Avoid cutting the fork subassembly on the one hand and have the tolerance to lead to dieing between the anti-dazzling screen 5, on the other hand avoids cuting danger, anti-dazzling screen 5 adopts flexible material, makes it touch each other when closed again can elastic deformation adaptation tolerance, also can utilize self elasticity to produce the guard action when cuting dangerous the emergence. For the specific shape of the light shielding sheet 5, it is preferable that the surface shape of the light shielding sheet 5 is axisymmetric, and the edge of the light shielding sheet is provided with a closing part protruding outwards, so that the closing parts gradually approach to each other until the closing parts are closed when the scissors assembly is extended.

In addition, the light-shielding sheets 5 are not necessarily completely attached in the thickness direction, and thus a curved air duct is formed for ventilation. Even if the space between the shading sheets 5 is completely closed to shade light, shield wind and rain, the ventilation function is still achieved.

Referring to fig. 5, for the specific structure of the driving system 1, preferably, the driving system 1 includes a driving motor 8, a synchronizing shaft 9, a driving sprocket 10, a driven sprocket 11, and a transmission chain 12; the driving motor 8 is fixedly arranged on the top beam 2 and is in transmission connection with the synchronizing shaft 9; the synchronous shaft 9 is rotationally connected to the top beam 2, and two ends of the synchronous shaft 9 are respectively in transmission connection with a driving chain wheel 10 rotationally connected to the top end of the guide rail 3; the driven chain wheel 11 is rotatably connected to the bottom end of the guide rail 3, the transmission chain 12 is wound on the driving chain wheel 10 and the driven chain wheel 11, and the sliding block 7 is in transmission connection with the transmission chain 12.

The driving motor 8 is generally a speed reducing motor, and is controlled by a special control system, and the control mode is not limited to key, remote control, network control and the like. The driving motor 8 drives the synchronous shaft 9 to rotate forwards or backwards, so that the driving chain 12 is driven to rotate forwards or backwards through the driving chain wheel 10 and the driven chain wheel, and the bottom curtain 6 is driven to lift.

In order to further optimize the anti-pinch protection function of the product and improve the safety, a torque protection device 13 is preferably arranged between the driving motor 8 and the synchronizing shaft 9. The device uses torque as a limit, when a human body or other objects are clamped by the scissors assembly, the further movement of the scissors assembly is blocked, and the resistance is finally transmitted between the driving motor 8 and the synchronous shaft 9 to form resistance torque. When the resisting moment is too large, the torque protection device 13 cuts off the power between the driving motor 8 and the synchronizing shaft 9, and the condition that people clamp or articles are damaged due to further movement of the scissor assembly is avoided.

Referring to fig. 6, further, the torque protection device 13 includes a housing 15, an input shaft 16, a rotating gear 17, a first gear 18, a second gear 19 and a damper 21; the input shaft 16 is in a T shape and is provided with an input end and two gear mounting ends arranged oppositely in a mirror direction, and the input end of the input shaft 16 penetrates through the shell 15 to be in transmission connection with the driving motor 8; the two rotating gears 17 are respectively and rotatably connected with the two gear mounting ends of the input shaft 16; an output shaft 20 which protrudes outwards in the axial direction is arranged in the center of the second gear 19, and the output shaft 20 penetrates through the shell 15 and is in transmission connection with the synchronous shaft 9; the first gear 18 is disposed opposite to the second gear 19 in tooth surface and simultaneously meshes with the two rotary gears 17; the resistance between the housing 15 and the first gear 18 is adjusted by adjusting the damping 21.

The working principle is as follows: the power of the driving motor 8 is input through the input shaft 16, and at this time, because the adjustable damping 21 forms resistance to the first gear 18 to force it to be fixed, the rotating gear 17 will engage with the first gear 18 to rotate, thereby driving the second gear 19 to rotate at a faster speed to output torque to the synchronizing shaft 9. If an obstacle is clamped on the scissors assembly to prevent the movement of the curtain 4, the resistance torque on the synchronizing shaft 9 is increased, when the resistance torque is larger than the stabilizing torque generated by the adjusting damper 21, the first gear 18 slips relative to the shell 15, and the torque output by the driving motor 8 is consumed on the first gear 18 instead. This avoids shearing risks without damaging the drive system 1.

Preferably, adjacent scissor assemblies are offset in thickness due to the increased lateral dimension of the scissor assemblies when folded. Preferably, the holding tank more than the twice is seted up respectively to back timber 2 and end curtain 6, and the holding tank of back timber 2 sets up with the holding tank of end curtain 6 relatively, cuts the tip of fork subassembly and inlays and locate in the holding tank. Therefore, the movements between the adjacent scissor assemblies cannot interfere with each other, and the space in the transverse direction is saved.

The novel sunshade curtain provided by the invention can realize the state synchronous control of the whole curtain mat 4 and realize the synchronous shielding, lighting or semi-lighting ventilation function. The scissors assembly has the anti-shearing protection of ascending and descending two directions, and can not suffer from shearing risk because fingers or other components pass through the ventilation gap of the scissors assembly. Even if the shading sheet is completely shielded, a channel for air circulation can be formed after the shading sheet 5 is closed, and meanwhile, the functions of wind prevention and ventilation are achieved.

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.
