Technical Field

[0001] The present invention relates to the field of decorative building materials, and in particular to a flexible mechanical sunshade. Background Art

[0002] Sunshade products have both shading and ventilation functions and are gradually becoming popular in modern buildings.

[0003] Existing mechanical sunshades generally use rigid slats. The shading range is then controlled and adjusted by the swinging of the slats. The drive system of these flexible mechanical sunshades is relatively complex, and the adjustment process is relatively slow. Furthermore, mechanical sunshades generally struggle to achieve the desired opening and closing of localized areas to allow light and air to flow as needed. For example, in an office, if the same mechanical sunshade covers a certain area that needs to be light-free while another area needs to be shaded, existing mechanical sunshades cannot meet these requirements.

[0004] It is not difficult to see that the existing technology still has certain defects. Summary of the Invention

[0017] The flexible mechanical sunshade provided by the present invention has the following advantages:

[0018] The curtain is composed of multiple flexible unit pieces. The state of the unit piece can be changed by using the opening and closing slider to achieve the opening and closing of the local area to allow light and air to pass through.

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention and the accompanying drawings. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] Example 1

[0045] See also Figures 1 to 3 The embodiment of the present invention provides a flexible mechanical sunshade, comprising a frame 1, curtain pieces 2, an opening and closing slider 3, a rotating end 4, a guide rail 10 and a rotary drive group; a plurality of curtain pieces 2 are arranged in parallel, wherein each curtain piece 2 is composed of a plurality of flexible unit pieces 5, one end of the unit pieces 5 is aligned, and the other end of the unit pieces 5 is arranged along the thickness direction, and the two ends of the unit pieces 5 are respectively fixedly connected to the two rotating ends 4; the rotating ends 4 are respectively rotatably connected to the frame 1; a guide rail 10 is fixed between each group of rotating ends 4, and the opening and closing slider 3 is slidably connected to the guide rail 10; the opening and closing slider 3 It includes a first sub-slider 6 and a second sub-slider 7 fixedly connected to each other and set at a distance. The first sub-slider 6 is provided with a plurality of first slide grooves 8 that match the unfolded arrangement of the unit pieces 5, and the second sub-slider 7 is provided with a second slide groove 9 that matches the aligned arrangement of the unit pieces 5; one end of each unit piece 5 is respectively sleeved in the first slide groove 8, and the other end is sleeved in the second slide groove 9, so that the unit piece 5 on the side of the first sub-slider 6 of the curtain piece 2 is in an unfolded state, and the unit piece 5 on the side of the second sub-slider 7 is in an aligned closed state; the rotary drive group is transmission-connected to the rotary end head 4 to drive the curtain piece 2 to rotate.

[0046] The curtain piece 2 of the present invention is divided into multiple unit pieces 5. The curtain piece 2 itself can independently control the swing angle through the rotation drive group, and the opening and closing of the unit piece 5 can be independently controlled by the opening and closing slider 3, thereby forming a variety of states and arbitrarily changing the light and air permeability of the local area of the sunshade.

[0047] In the fully closed state, the opening and closing slider 3 slides until its ends mate with the end cap. Specifically, the first sub-slider 6, which drives the unit panels 5 to unfold, mates with the corresponding rotating end cap 4. The second slot 9 on the second sub-slider 7 closes the unit panels 5 into a single piece. At this point, the rotary drive assembly is controlled to align the curtain panels 2 closely, completely blocking out light. To fully open, the rotary drive assembly simply rotates the curtain panels 2 a certain angle to allow light to pass between them.

[0048] To adjust localized light and air permeability, adjust the curtain slats 2 to the desired angle and then control the sliding of the opening and closing slider 3 accordingly. As the opening and closing slider 3 slides, the first sub-slider 6 drives the unit slats 5 to open, creating gaps between the unit slats 5 for light and air to pass through. The size and position of this light and air permeability area are determined by the sliding position of the opening and closing slider 3. Therefore, this structure enables precise control of localized light and air permeability to meet the needs of different indoor areas.

[0049] It should be noted that the specific material of the curtain slats 2 is not limited herein, as long as it exhibits sufficient toughness. Furthermore, the number of opening and closing sliders 3 is not limited to one per set of curtain slats 2. If more precise control is required, multiple opening and closing sliders 3 may be provided per set of curtain slats 2. Furthermore, the present invention does not limit the specific extension direction of the curtain slats 2. While conventional curtain slats 2 extend vertically, they may also extend horizontally or even at an angle.

[0050] The guide rail 10 stabilizes the sliding movement of the opening and closing slider 3. However, the presence of the guide rail 10 can affect the appearance of the curtain slat 2. Given that the curtain slat 2 is composed of unitary panels 5, the guide rail 10 is preferably positioned on the side of the curtain slat 2, joining the unitary panels 5 to form a closed connection. In addition to providing stable guidance for the opening and closing slider 3, the guide rail 10 also fulfills the same function as the unitary panels 5, providing shade.

[0051] The unit sheets 5 can be arranged in an overlapping manner in the thickness direction, but this arrangement is obviously inefficient in the fully closed state. Therefore, a more preferred arrangement is that the unit sheets 5 on each group of curtain sheets 2 are staggered and joined to each other on the sides.

[0052] Furthermore, the unit pieces 5 of each set of curtain panels 2 are provided with a zipper (not shown) on the joint edge that cooperates with each other. A slider (not shown) that cooperates with the zipper is fixed to the second sub-slider 7 of the opening and closing slider 3, so that the zipper is closed or released when the opening and closing slider 3 slides. In this way, when the unit pieces 5 are spliced into a curtain panel 2 under the restraint of the second slide groove 9, the joint portion will be tightly closed by the zipper.

[0053] Alternatively, another method is used to close the unit pieces 5: the unit pieces on each set of curtain pieces are provided with magnetic strips (not shown) on the joint edges, so that when the opening and closing slider 3 slides, the unit pieces 5 are stretched open or attracted to each other by the magnetic strips.

[0054] The rotary drive group includes two structural schemes. Figure 4 As a first preferred embodiment, the rotary drive assembly includes an electric push rod 11, a connecting rod 12, and a rocker 13. The rear end of the electric push rod 11 is hinged to the frame 1, its movable end is hinged to the connecting rod 12, the rocker 13 is fixedly connected to the rotating end 4, and the connecting rod 12 is hinged to all the rockers 13. By controlling the extension of the electric push rod 11, the swing angle of the curtain slat 2 can be controlled.

[0055] See also Figure 5 Alternatively, as another preferred embodiment, the rotary drive assembly includes a first motor 14, a pulley 15, and a transmission belt 16. The first motor 14 is fixedly mounted on the frame 1, with one pulley 15 in transmission connection with the first motor 14. All rotating ends 4 at the same end are respectively in transmission connection with pulleys 15, with the transmission belt 16 wound between the pulleys 15. The pulley 15 occupies less space than the connecting rod 12 and the electric push rod 11, but the transmission process is relatively less labor-saving, and the first motor 14 requires a larger driving torque.

[0056] The present invention also includes a slider drive group for driving the opening and closing slider 3. The specific structure of the slider drive group has two schemes:

[0057] See also Figure 6 As a first preferred solution, in this embodiment, the slider drive group includes a control unit (not shown), a second motor 17, a winding wheel 18 and a traction wire 19; the second motor 17 is installed on the skeleton 1 and is transmission-connected to the winding wheel 18, and the second motor 17 is control-connected to the control unit; one end of the traction wire 19 is connected to the winding wheel 18 and the traction wire 19 is wound around the winding wheel 18, and the other end of the traction wire 19 is fixedly connected to the opening and closing slider 3.

[0058] The control unit controls the rotation of the second motor 17, thereby controlling the number of turns of the winding wheel 18 and adjusting the sliding position of the opening and closing slider 3. The traction wire 19 not only drives the opening and closing slider 3 to slide, but is also relatively thin, making it less likely to obstruct vision when the curtain slats 2 are in the light-transmitting state, thus facilitating concealment. In this solution, the control unit can independently control each second motor 17, and thus each opening and closing slider 3, according to a program, providing the most refined control.

[0059] As a further preference, the opening and closing slider 3 is located on the other side of the traction wire 19 and is connected to a reset device; the reset device includes a connecting wire 21, a reset spring and a reset roller 20; the reset roller 20 is installed on the frame 1, and is located at the end position of the curtain 2 facing the opening and closing slider 3; the reset roller 20 and the frame 1 are elastically connected by a reset spring, one end of the connecting wire 21 is fixedly connected to the reset roller 20 and is wound around the surface of the reset roller 20, and the other end of the connecting wire 21 is connected to the opening and closing slider 3.

[0060] By resetting the mainspring, the resetting roller 20 always generates an elastic force that drives the connecting wire 21 to wind and shrink, pulling the opening and closing slider 3 so that it has a resetting trend. This pulling force is in the opposite direction to the driving force of the slider drive group.

[0061] Furthermore, in order to prevent the traction wire 19 from shaking and affecting the landscape, and to prevent the traction wire 19 from being entangled and other problems, a wire groove is provided axially inside the guide rail 10, and the traction wire 19 is embedded in the wire groove.

[0062] Example 2

[0063] The only difference between this embodiment and the first embodiment lies in the specific structural solution of the slider drive group.

[0064] See also Figure 7 In this embodiment, as another preferred solution, the slider drive group includes a third motor 22, a screw rod 23, a synchronous belt 24 and a lifting plate 25; the screw rod 23 is fixedly installed on both sides of the frame 1 and is transmission-connected to the third motor 22; the screw rods 23 on both sides are synchronously transmission-connected through the synchronous belt 24; the lifting plate 25 is fixedly connected to the nut of the screw rod 23, and the opening and closing slider 3 is connected to the lifting plate 25, so that the lifting plate 25 drives the opening and closing slider 3 to move.

[0065] The slider drive assembly of this embodiment employs a simplified approach, employing synchronized sliding control of all opening and closing sliders 3. While the level of refined control is somewhat lower than in Example 1, it is easier to implement, with lower assembly and program manipulation requirements. It should be noted that the specific connection structure between the lifting plate 25 and the opening and closing sliders 3 is not specifically defined herein; it suffices as long as the lifting plate 25 can drive the opening and closing sliders 3 along the curtain slats 2. Since the curtain slats 2 also have a rotational function, the opening and closing sliders 3 also have a rotational function and require a rotational connection to the lifting plate 25 or a similar connection method.

[0066] In addition, in order to cope with power outages, a handle (not shown) can be added to assist manual control. The handle is detachably connected to the screw drive, and the opening and closing slide block 3 can be driven to move by manually installing the handle and rotating it.

[0067] Other technical features of this embodiment, such as the structural scheme of the rotation drive group, the arrangement of the unit pieces 5 and the closed structure, can all adopt the technical scheme of the first embodiment, and their working principles are exactly the same, so they will not be described in detail here.

[0068] The flexible mechanical sunshade provided by the present invention features an innovative design in which the curtain slats 2 are composed of multiple flexible unit sheets 5. The state of each unit sheet 5 can be individually adjusted using an opening and closing slider 3, achieving localized opening and closing for light and air permeability. A rotation drive group and a slider drive group control the overall rotation of the curtain slats 2 and the opening and closing of the unit sheets 5, respectively. These coordinated actions enable control of multiple light transmission states, facilitating precise control. Furthermore, a zipper structure allows the unit sheets 5 to be spliced together as the opening and closing slider 3 slides, preserving the integrity of the entire curtain slat 2.

[0069] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
