Description

Technical Field

[0001] This utility model relates to the field of louver installation technology, and more specifically, to an upward-folding sunshade louver. Background Technology

[0002] Shading louvers are generally used for indoor and outdoor shading and ventilation. The amount of air and light passing through can be adjusted by changing the opening size of the shading panel.

[0003] Existing sunshade louvers use drive screws. For example, Chinese patent CN220167764U discloses a screw-lifted sunshade panel, including a curtain wall body. Each slide rail has a drive screw along its length. One end of each drive screw is connected to a drive mechanism. Each drive screw is sleeved with a first sliding mechanism and a second sliding mechanism. The first sliding mechanism is connected to the first sunshade panel and fixed on the slide rail. The drive mechanism drives the drive screw to rotate, thereby causing the second sliding mechanism to slide within the slide rail. This allows the second sunshade panel to move up and down relative to the slide rail. Since the first and second sunshade panels are hinged, the first sunshade panel also rotates at the first sliding mechanism, dividing the entire sunshade panel into two panels, reducing weight. Furthermore, the screw-driven method is not affected by the weight of the sunshade panel compared to traditional support rods, making it more convenient to adjust the opening and closing size of the sunshade panel and regulate the amount of air and light passing through.

[0004] However, the drive screw is expensive, and maintenance requires disassembling and replacing the entire screw and louvers. It is also only suitable for small-scale curtain walls, which limits its application.

[0005] Therefore, there is a need to provide a more widely applicable and easy-to-install / disassemble sunshade louver. Utility Model Content

[0006] In view of this, in order to solve the above problems, this utility model proposes an upward-folding sunshade louver, including a curtain wall body 1. The curtain wall body 1 is provided with a frame 2 arranged parallel to the length direction of the curtain wall body 1. The curtain wall body 1 is provided with two sets of drive mechanisms and two sets of chains 4 on the left and right sides. Each set of chains 4 is sleeved with a corresponding set of drive mechanisms. The curtain wall body 1 is provided with two sets of upper and lower slide rails at intervals. The slide rails are provided with upper louvers 61 and lower louvers 62. The upper louvers 61 are connected to one set of chains 4, and the lower louvers 62 are connected to the other set of chains 4. The upper louvers 61 and lower louvers 62 are controlled by the two sets of drive mechanisms and chains 4 respectively. The upper louvers 61 and lower louvers 62 can be opened and closed individually or simultaneously. By setting the drive mechanism and chains 4 to drive the louvers, the cost is low and the disassembly and assembly are convenient.

[0007] A type of upward-folding sunshade louver includes a curtain wall body 1, characterized in that: a frame 2 is provided on the outside of the curtain wall body 1, parallel to the length direction of the curtain wall body 1; two sets of drive mechanisms and two sets of chains 4 are provided on the left and right sides inside the curtain wall body 1, each set of chains 4 is sleeved with a corresponding set of drive mechanisms; two sets of upper and lower slide rails are provided parallel to each other on the outside of the curtain wall body 1, and upper louvers 61 and lower louvers 62 are provided on the slide rails; the upper louvers 61 are connected to one set of chains 4, and the lower louvers 62 are connected to another set of chains 4; the upper louvers 61 and lower louvers 62 are controlled by the two sets of drive mechanisms and chains 4 respectively, and the upper louvers 61 and lower louvers 62 can be opened and closed individually or simultaneously.

[0008] Furthermore, the slide rail includes an upper slide rail 51 and a lower slide rail 52, with a barrier strip between the upper slide rail 51 and the lower slide rail 52 to prevent them from being connected. The upper louver 61 is connected to a first pulley group, and the upper louver 61 slides between the upper slide rails 51 via the first pulley group. The lower louver 62 is connected to a second pulley group, and the lower louver 62 slides between the lower slide rails 52 via the second pulley group.

[0009] Furthermore, both the upper louver 61 and the lower louver 62 include two sub-blades, the one near the end being the first sub-blade 633 and the one near the middle being the second sub-blade 644, and the first sub-blade 633 and the second sub-blade 644 are rotatably connected by a first hinge 71.

[0010] Furthermore, the end of the first sub-blade 633 is provided with a second hinge 72, one side of the second hinge 72 is fixed to the end of the frame 2, and the other side is connected to the end of the first sub-blade 633.

[0011] Furthermore, the end of the second sub-blade 644 of the upper louver 61 is connected to the first pulley group. The first pulley group includes two first pulleys 8 symmetrically arranged on the left and right sides. The first pulleys 8 are placed in the upper slide rail 51. The chain 4 is provided with a fixing block 43. The fixing block 43 is connected to the first pulley 8 through a connector 44. The driving mechanism drives the chain 4 and the fixing block 43 to drive the first pulley 8 to slide in the upper slide rail 51, so that the upper louver 61 opens and closes.

[0012] Furthermore, the end of the second sub-blade 644 of the lower louver 62 is connected to a second pulley group, which includes two second pulleys 9 symmetrically arranged on the left and right sides, and the second pulleys are placed in the lower rail 52.

[0013] Furthermore, the chain 4 is provided with a fixing block 43, and the fixing block 43 is connected to the second pulley 9 through a connector 44. The connector 44 and the fixing block 43 are rotatably connected. The driving mechanism drives the chain 4 and the fixing block 43 to drive the second pulley 9 to slide in the lower rail 52, so that the lower louver 62 opens and closes.

[0014] Furthermore, the driving mechanism includes a motor 33, which is located at one end of the chain 4. The end of the chain 4 closest to the motor 33 is provided with a first gear disk 41, and the end of the chain 4 furthest from the motor 33 is provided with a second gear disk 42. The first gear disk 41 and the second gear disk 42 mesh with the chain 4. The motor 33 drives the first gear disk 41, thereby driving the chain 4. The chain 4 drives the second gear disk 42, causing the fixed block 43 connected to the chain 4 to be driven by the chain 4. This causes the first pulley group to slide in the upper slide rail 51, and the second pulley group to slide in the lower slide rail 52.

[0015] Furthermore, the two sets of drive mechanisms and chains 4 operate independently. One set of drive mechanisms and chains 4 controls the opening and closing of the upper louver 61, while the other set of drive mechanisms and chains 4 controls the lower louver 62. When only the upper louver 61 or the lower louver 62 needs to be opened or closed, one set of motors 33 is activated. When both the upper louver 61 and the lower louver 62 need to be opened and closed simultaneously, both sets of motors 33 are activated simultaneously.

[0016] Furthermore, when both the upper louver 61 and the lower louver 62 are closed, the fixing block 43 slides to the middle with the chain 4, and the first hinge 71 closes. At this time, the first hinge 71 is located between the fixing block 43 and the second hinge 72.

[0028] The slide rail includes an upper slide rail 51 and a lower slide rail 52. A barrier strip is provided between the upper slide rail 51 and the lower slide rail 52 so that the upper slide rail 51 and the lower slide rail 52 are not connected. The upper louver 61 is connected to a first pulley group and slides between the upper slide rails 51 through the first pulley group. The lower louver 62 is connected to a second pulley group and slides between the lower slide rails 52 through the second pulley group.

[0029] Both the upper louver 61 and the lower louver 62 include two sub-blades, the one near the end being the first sub-blade 633 and the one near the middle being the second sub-blade 644. The first sub-blade 633 and the second sub-blade 644 are rotatably connected by a first hinge 71.

[0030] The end of the first sub-blade 633 is provided with a second hinge 72. One side of the second hinge 72 is fixed to the end of the frame 2, and the other side is connected to the end of the first sub-blade 633.

[0031] The end of the second sub-blade 644 of the upper louver 61 is connected to the first pulley group.

One set of drive mechanisms and chains 4 controls the opening and closing of the upper louver 61, and the other set of drive mechanisms and chains 4 controls the lower louver 62. When only the upper louver 61 or the lower louver 62 needs to be opened or closed, one set of motors 33 is turned on. When both the upper louver 61 and the lower louver 62 need to be opened and closed at the same time, both sets of motors 33 are turned on at the same time.

[0036] When both the upper louver 61 and the lower louver 62 are closed, the fixing block 43 slides to the middle with the chain 4, and the first hinge 71 closes. At this time, the first hinge 71 is located between the fixing block 43 and the second hinge 72.
