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 5, an embodiment of the present invention provides a folding sunshade curtain, which includes a guide rail 1, a slider 2, a transmission gear 3, an upper sunshade 4, a lower sunshade 5, a curtain bottom 6 and a driving device; the upper sunshade piece 4 and the lower sunshade piece 5 are formed into a group, and the front side edges of each group of upper sunshade piece 4 and lower sunshade piece 5 are hinged with each other; the front side of the upper sunshade sheet 4 is provided with a convex shading part 7, and the front side of the lower sunshade sheet 5 is provided with a light transmission notch 8 matched with the shading part 7; the tail parts of the upper sunshade piece 4 and the lower sunshade piece 5 are respectively and fixedly connected with the transmission gear 3, the tail parts of the upper sunshade piece 4 and the lower sunshade piece 5 of the adjacent group are opposite, are respectively and rotatably connected with the sliding block 2, and are mutually meshed and transmitted through the transmission gear 3, so that the upper sunshade piece 4 and the lower sunshade piece 5 of the adjacent group swing in opposite directions by corresponding angles; the sliding block 2 is in sliding connection with the guide rail 1, and the guide rail 1 is arranged on two sides of the upper sunshade piece 4 and the lower sunshade piece 5 in parallel; the curtain bottom sheet 6 is connected below the lower sunshade sheet 5 positioned at the bottom and is in sliding connection with the guide rail 1; the driving device extends along the guide rail 1 and is connected with the curtain bottom sheet 6 in a transmission way.
The working principle of the invention is as follows:
the driving device can act on the curtain bottom sheet 6 to drive the curtain bottom sheet to slide along the guide rail 1. The upper sunshade piece 4 and the lower sunshade piece 5 are hinged to form a curtain piece structure, the curtain piece structure is similar to an organ shape, and the sliding of the curtain bottom piece 6 drives the curtain bottom piece to stretch for shielding or shrink for folding. Meanwhile, the tail parts of the upper sunshade piece 4 and the lower sunshade piece 5 of the adjacent group are meshed and driven by the driving gear 3, so that the whole sunshade is in linkage relation, and as long as the curtain bottom piece 6 is driven to slide, the rotation amplitude of all the upper sunshade piece 4 and the lower sunshade piece 5 is corresponding, and the problem that the local expansion or contraction amplitude of the upper sunshade piece 4 or the lower sunshade piece 5 is different can not occur.
Meanwhile, the shading parts 7 on the front sides of the upper shading sheet 4 and the lower shading sheet 5 are matched with the light transmission gaps 8, and when the upper shading sheet 4 and the lower shading sheet 5 are fully extended to shade, the shading parts 7 are covered on the light transmission gaps 8 to fully shade. When the upper sunshade piece 4 and the lower sunshade piece 5 slightly shrink, fold and swing, the light shielding part 7 swings and opens, so that light and fresh air can realize semi-transmission ventilation through the light transmission notch 8.
It should be noted that the gear ratio of the transmission gear 3 between the upper sunshade sheet 4 and the lower sunshade sheet 5 of the adjacent group is not necessarily one to one. If the height of the upper sunshade piece 4 is equal to the height of the lower sunshade piece 5, the upper sunshade piece 4 and the lower sunshade piece 5 form an isosceles triangle structure, the rotation of the upper sunshade piece 4 and the lower sunshade piece 5 is opposite in direction and equal in amplitude, and the connecting transmission parts of the adjacent groups are also supposed to adopt a one-to-one transmission ratio. However, if the height of the upper sunshade piece 4 is not equal to the height of the lower sunshade piece 5, the triangle structure formed by the two is not a simple isosceles triangle, the rotation amplitude of the upper sunshade piece 4 and the lower sunshade piece 5 is not equal, and the connection transmission parts of adjacent groups can also adopt corresponding transmission ratios to realize special linkage effect.
The invention has two preferred embodiments, differing in the mode of action for the half-open state. Referring to fig. 3, preferably, in the present embodiment, the driving device includes a pulley 9, a driving belt 11, a driving motor 10 and a connecting member; the pulleys 9 are at least provided with two pulleys and are arranged along the guide rail 1, the driving belt 11 is wound on the pulleys 9, the driving motor 10 is in transmission connection with one of the pulleys 9, and the connecting component is connected between the driving belt 11 and the curtain bottom sheet 6.
The driving device adopts a belt transmission scheme, can easily realize the bidirectional sliding driving of the curtain bottom sheet 6, and further drives the upper sunshade sheet 4 and the lower sunshade sheet 5 to stretch or fold. If the semi-open ventilation and light transmission of the upper sunshade piece 4 and the lower sunshade piece 5 are needed, the curtain bottom piece 6 can be controlled to slide for a short stroke to drive the upper sunshade piece 4 and the lower sunshade piece 5 to be folded in a small range, so that the semi-ventilation and light transmission are realized.
However, the solution of this embodiment results in a half-open light-transmitting state, in which the curtain sheet 6 is at a certain height from the bottom, the partial space being in a fully open state. The height travel is about 10% -30% of the total sunshade travel, depending on the half-open amplitude.
Referring to fig. 4, specifically, preferably, the upper sunshade 4 includes an upper sheet 14 and an upper swing arm 15; the lower sun-shading sheet 5 comprises a lower sheet 16 and a lower swing arm 17; the back sides of the upper sheet 14 and the lower sheet 16 are respectively fixedly connected with an upper swing arm 15 and a lower swing arm 17, and the tail parts of the upper swing arm 15 and the lower swing arm 17 are respectively fixedly connected with a transmission gear 3.
The upper sunshade sheet 4 and the lower sunshade sheet 5 adopt the split assembly structure, the upper sheet 14 and the lower sheet 16 can be manufactured by plates, and can be processed into various special shapes, and the light shielding part 7 and the light transmission notch 8 can be cut, so that the processing is facilitated. The upper swing arm 15 and the lower swing arm 17 are used as skeleton structures for connecting with the transmission gear 3.
In addition, the structural characteristics of the present invention determine that each set of the upper and lower sun-shading sheets 4 and 5 cannot be completely straightened. Therefore, preferably, the front ends of the upper swing arm 15 and the lower swing arm 17 are provided with a limiting portion (not shown) protruding from the guide rail 1, and the limiting portion is abutted against the surface of the guide rail 1 to limit when the upper sunshade 4 and the lower sunshade 5 are closed, so that the upper sunshade 4 and the lower sunshade 5 keep an included angle arrangement. Therefore, the upper sunshade piece 4 and the lower sunshade piece 5 cannot be propped up to death in the folding process, and when the shielding is completely stretched, the limiting part is propped against the surface of the guide rail 1, so that the sunshade windproof function is reserved.
The upper sunshade piece 4 and the lower sunshade piece 5 of the adjacent group occupy a certain space at the joint part due to the meshing structure of the transmission gear 3. In order to solve this problem, it is preferable that the back side of the transmission gear 3 is provided with a shielding sheet 18, and both sides of the shielding sheet 18 are fixedly connected with the slider 2, respectively. Thus, when the sun shield is viewed from the back side, the transmission gear 3 is not seen, and thus the product is maintained to be beautiful. At the same time, the shielding sheet 18 also prevents the upper and lower sun-shading sheets 4 and 5 from generating gap light leakage at the tail.
In order to match the control of the driving system, it is further preferable that the curtain sheet 6 is provided with an induction switch (not shown). When the curtain sheet 6 touches the window sill or an obstacle to generate a sensing signal, it is determined that the curtain sheet 6 is lowered into place.
Example two
The difference between this embodiment and the first embodiment is that: the driving means act differently.
Referring to fig. 6 to 7, in the present embodiment, the sunshade of the present invention preferably further includes a shading compensation sheet 22, a winding drum 21 and a spring (not shown); the plurality of shading compensation sheets 22 are connected end to end and wound on the surface of the winding drum 21, the winding drum 21 is rotatably arranged at the top of the guide rail 1, and a spring is arranged between the winding drum 21 and the top of the guide rail 1, so that the shading compensation sheets 22 are elastically wound upwards and accommodated.
The driving device correspondingly matched with the driving device comprises a belt wheel 9, a transmission belt 11, a driving motor 10, an upper connecting hook 20 and a lower connecting hook 12; the belt wheels 9 are at least provided with two belt wheels and are arranged along the guide rail 1, the driving belt 11 is wound on the belt wheels 9, and the driving motor 10 is in transmission connection with one belt wheel 9; the upper connecting hook 20 and the lower connecting hook 12 are arranged up and down and are respectively connected with the upper end and the lower end of the driving belt 11 in a transmission way; the back side of the shading compensation sheet 22 at the bottom is provided with an upper connecting part 19 matched with the upper connecting hook 20, the back side of the curtain bottom sheet 6 is provided with a lower connecting part 13 matched with the lower connecting hook 12, the upper connecting hook 20 is detachably connected with the upper connecting part 19, and the lower connecting hook 12 is detachably connected with the lower connecting part 13.
Aiming at the sun-shading semi-open ventilation and light transmission state, the driving device in the embodiment has the following action modes: when the bottom of the curtain sheet 6 is lowered to the bottom, after the upper sunshade sheet 4 and the lower sunshade sheet 5 are completely extended and shielded, the lower connecting hook 12 of the driving device is separated from the curtain sheet 6, the upper connecting hook 20 acts on the shading compensation sheet 22, the alignment generates a downward pressing effect, and when all the upper sunshade sheets 4 and the lower sunshade sheets 5 are forced to be contracted and folded downwards to realize half-open, the shading compensation sheet 22 is pulled to shield downwards against the elastic force of the spring so as to compensate the stroke of the sunshade top.
When the folding is required to be fully opened, the driving device drives the upper connecting hook 20 to move upwards, and the shading compensation sheet 22 is wound and stored upwards under the elasticity of the spring. The upper coupling hooks 20 are then disengaged from the shade compensation sheet 22, while the lower coupling hooks 12 act on the shade sheet 6 to control the folding of the entire shade.
In this embodiment, the remaining technical features may be inherited from the first embodiment, and will not be described herein.
The folding sunshade curtain provided by the invention maintains the function of completely opening or completely shielding the sunshade in the prior art, and simultaneously can realize the linkage of all the upper sunshade plates 4 and the lower sunshade plates 5 of the whole sunshade, so that the whole sunshade can uniformly transmit light and breathe. The operation mode is simple, and the motor can be realized by changing the rotation amplitude of the motor or changing the rotation direction of the motor.
