Description

Technical Field

[0001] This utility model belongs to the technical field of sunshade devices, and more specifically, relates to a sunshade device with a traction mechanism. Background Technology

[0002] Sunshade curtains are used to effectively block sunlight from building windows, preventing excessively high indoor temperatures that could cause discomfort or premature aging of items due to prolonged sun exposure. For large-scale shading applications, such as horizontal, sloping, and dome-shaped structures, sunshade curtains with an FTS (Flexible Transmission System) are typically used. The FTS system consists of two motors, one mounted on the fabric and the other on the steel cable. When the fabric unfolds to the predetermined position, the motor inside the fabric tube reverses, thus stretching the fabric. This system is suitable for large glass roofs.

[0003] However, the existing sunshade curtains with FTS systems have limited application length, with an extension length of only 15m, making it difficult to provide sunshade for large-span glass roofs. This limits the applicable scope of the sunshade curtains. Therefore, how to improve the existing sunshade devices to expand their applicable scope has become an urgent problem for those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing sunshade devices are difficult to use for shading large-span glass roofs, thus limiting their applicability.

[0005] To achieve the above objectives, this utility model provides a sunshade device with a traction mechanism, including two sunshade mechanisms, a guide mechanism, and a first traction mechanism and a second traction mechanism installed between the two sunshade mechanisms.

[0006] Each of the two sunshade mechanisms includes a fabric roll tube and a sunshade curtain connected at one end to the fabric roll tube;

[0007] The guiding mechanism includes two guide ropes arranged on both sides of the sunshade, and a first guide pulley and a second guide pulley are hung side by side on each guide rope;

[0008] Both the first traction mechanism and the second traction mechanism include traction plates connected to the lower ends of the first guide pulley and the second guide pulley, respectively. One side of the traction plate is connected to the other end of the sunshade adjacent to it, and the other side is connected to a traction component.

[0009] The traction assembly includes a tensioning unit and a first traction rope and a second traction rope disposed opposite to each other at both ends of the traction plate. The tensioning unit can drive the traction plate to move along the guide rope through the first traction rope and the second traction rope to traction the sunshade.

[0010] Optionally, the tensioning unit includes a first directional pulley, a second directional pulley, and a rope winder, wherein the first traction rope and the second traction rope are respectively wound around the first directional pulley and the second directional pulley, and are both connected to the rope winder.

[0011] Optionally, the two ends of the traction plate are symmetrically provided with connecting portions for connecting the first traction rope and the second traction rope.

[0012] Optionally, both the first traction mechanism and the second traction mechanism include a first base plate and a second base plate disposed opposite to each other at both ends of the traction plate, wherein the first base plate and the second base plate are respectively used to connect the first directional pulley and the second directional pulley to the outer wall.

[0013] Optionally, a cover plate is provided below both the first base plate and the second base plate to shield the first guide pulley and the second guide pulley.

[0014] Optionally, the rope winder includes a rope winding tube and a rope winding tube drive unit, wherein the rope winding tube is disposed on one side of the winding tube, and the rope winding tube drive unit is used to drive the rope winding tube to rotate forward or backward.

[0015] Optionally, the fabric roll tube includes a roll tube and a roll tube drive unit for driving the roll tube to rotate, with one end of the sunshade curtain connected to the roll tube.

[0016] Optionally, the sunshade device may further include a control module for controlling and supplying power to the rope winding drive unit and the winding tube drive unit.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention proposes a sunshade device with a traction mechanism. By setting a guide mechanism and installing a first traction mechanism and a second traction mechanism between two sunshade mechanisms, both the first and second traction mechanisms are connected to a first guide pulley and a second guide pulley, respectively, via their traction plates. One side of the traction plate is connected to the other end of the adjacent sunshade curtain, and the other side is connected to a traction assembly. The tensioning unit in the traction assembly, through the first and second traction ropes, moves the traction plate along the guide rope, thereby tractioning the sunshade curtain. Compared to existing sunshade devices, this invention connects two sunshade mechanisms using the first and second traction mechanisms and can traction the sunshade curtain, thus overcoming length limitations and enabling the sunshade device to meet the requirements of shading large-span glass roofs, expanding the applicability of the sunshade device. Furthermore, the guide mechanism is positioned on both sides of the sunshade curtain, ensuring that the guide rope, the first traction rope, and the second traction rope do not obstruct the sunshade curtain, resulting in a significant sunshade effect and improved aesthetics.

[0019] As can be seen from the above, this utility model can effectively solve the problem that existing sunshade devices are difficult to use for sunshading large-span glass roofs, thus limiting their applicable scope.

[0045] Reference Figs. 1-3An embodiment of this utility model provides a sunshade device with a traction mechanism, including two sunshade mechanisms, a guide mechanism, and a first traction mechanism and a second traction mechanism installed between the two sunshade mechanisms.

[0046] Each of the two shading mechanisms includes a fabric roll tube and a shading curtain 1 with one end connected to the fabric roll tube;

[0047] The guiding mechanism includes two guide ropes 2 arranged on both sides of the sunshade curtain 1, and a first guide pulley 3 and a second guide pulley 4 are hung side by side on each guide rope 2;

[0048] Both the first traction mechanism and the second traction mechanism include a traction plate 5 connected to the lower ends of the first guide pulley 3 and the second guide pulley 4 respectively. One side of the traction plate 5 is connected to the other end of the adjacent sunshade curtain 1, and the other side is connected to a traction component.

[0049] The traction assembly includes a tensioning unit and a first traction rope 6 and a second traction rope 7 disposed opposite to each other at both ends of the traction plate 5. The tensioning unit can drive the traction plate 5 to move along the guide rope 2 through the first traction rope 6 and the second traction rope 7 to pull the sunshade curtain 1.

[0050] In one embodiment, the fabric roll tube includes a roll tube 8 and a roll tube drive unit for driving the roll tube 8 to rotate, with one end of the sunshade 1 connected to the roll tube 8. The roll tube drive unit is not shown.

[0051] In one specific embodiment, the length of the second guide pulley 4 is greater than the roll length of the first guide pulley 3.

[0052] Specifically, the traction plates connected to the lower ends of the first guide pulley and the second guide pulley respectively can be arranged in an overlapping manner under the drive of the tensioning component, and the roller tubes in the two sunshade mechanisms are parallel to the adjacent traction plates, so that the sunshade curtains in the two sunshade mechanisms can be kept horizontal to reduce light leakage and achieve a better shading effect.

[0053] In one specific embodiment, the two ends of the traction plate 5 are symmetrically provided with connecting parts 51 for connecting the first traction rope 6 and the second traction rope 7.

[0054] In one embodiment, the tensioning unit includes a first directional pulley 9, a second directional pulley 10, and a rope winder. A first traction rope 6 and a second traction rope 7 are respectively wound around the first directional pulley 9 and the second directional pulley 10, and are both connected to the rope winder.

[0055] In one specific embodiment, the rope winder includes a rope winding tube 11 and a rope winding tube drive unit. The rope winding tube 11 is disposed on one side of the fabric winding tube, and the rope winding tube drive unit is used to drive the rope winding tube 11 to rotate forward or backward. The rope winding tube drive unit is not shown.

[0056] Specifically, the winding tube drive unit can drive the traction plate to move along the guide rope by rotating the transmission end in the forward or reverse direction, so as to achieve the traction and tension of the sunshade curtain, and can cooperate with the winding tube drive unit to unfold or retract the sunshade curtain.

[0057] In addition, the first traction mechanism and the second traction mechanism can operate simultaneously or independently, so that the two sunshades can be pulled synchronously or only a single sunshade can be pulled according to the needs of use.

[0058] In addition, the rope winding tube drive unit and the tube winding drive unit are respectively located inside the rope winding tube and the tube winding tube. They are mainly composed of drive components such as motors and are driven by gears or belts. Their specific structures and working principles are existing technologies and will not be elaborated on here.

[0059] In one embodiment, the sunshade device further includes a control module (not shown) for controlling and supplying power to the rope winding drive unit and the tube winding drive unit. The control module is connected to an external power source to facilitate control of the sunshade device.

[0060] In one embodiment, both the first traction mechanism and the second traction mechanism include a first base plate 12 and a second base plate 13 disposed opposite to each other at both ends of the traction plate 5. The first base plate 12 and the second base plate 13 are respectively used to connect the first directional pulley 9 and the second directional pulley 10 to the outer wall.

[0061] In one specific embodiment, a cover plate 14 for shielding the first guide pulley 3 and the second guide pulley 4 is provided below both the first base plate 12 and the second base plate 13.

[0062] Specifically, the cover plate allows only a portion of the traction plates of both the first and second traction mechanisms to be exposed, while the first traction rope, the second traction rope, and the guide rope can be hidden, thus improving the aesthetics.

[0063] In one embodiment, the periphery of both the first directional pulley 9 and the second directional pulley 10 is provided with a plurality of hexagon socket head cap screws 15 for limiting the first traction rope 6 and the second traction rope 7, respectively. Specifically, the hexagon socket head cap screws can prevent the first traction rope and the second traction rope from disengaging from the first directional pulley and the second directional pulley, thereby ensuring the stability of the sunshade curtain in use.

[0064] In one embodiment, a guide bracket 16 is provided between the first guide pulley 3 and the second guide pulley 4 to guide the first traction rope 6 or the second traction rope 7. Specifically, the guide bracket can effectively prevent the first traction rope or the second traction rope from sinking downwards and affecting the installation of the sunshade curtain when it is under a large span of tension, thus further ensuring the stability of the sunshade curtain in use.

[0065] During installation, the sunshade device of this invention requires mounting the fabric roll tubes of the two sunshade mechanisms onto the wall below the glass roof. Then, the guide mechanism, the first traction mechanism, and the second traction mechanism are sequentially connected to the wall and the sunshade curtain. When the sunshade curtain needs to be unfolded, the control module first drives the roll tube drive unit and the rope drive unit, causing the roll tube drive unit to unroll and the rope drive unit to rewind, thus pulling the sunshade curtain to the middle section via the traction plate. The first and second traction ropes tension the traction plate. When the sunshade curtain needs to be retracted, the control module again drives the roll tube drive unit and the rope drive unit to reverse, retracting the sunshade curtain, or selectively unfolding or retracting one of the sunshade curtains.

[0066] The sunshade device with a traction mechanism proposed in this utility model is configured with a guide mechanism and a first traction mechanism and a second traction mechanism installed between two sunshade mechanisms. The first traction mechanism and the second traction mechanism are connected to the first guide pulley and the second guide pulley respectively through their traction plates. By connecting one side of the traction plate to the other end of the adjacent sunshade curtain and connecting the other side to a traction assembly, the tensioning unit in the traction assembly can drive the traction plate to move along the guide rope through the first traction rope and the second traction rope to achieve traction of the sunshade curtain.

[0067] Therefore, compared with existing sunshade devices, the sunshade device of this utility model uses a first traction mechanism and a second traction mechanism to connect two sunshade mechanisms and can pull the sunshade curtain, thereby breaking through the length limitation and enabling the sunshade device to meet the requirements of sunshading large-span glass roofs, thus expanding the applicable range of the sunshade mechanism. Moreover, the guide mechanism is set on both sides of the sunshade curtain, so that the guide rope, the first traction rope and the second traction rope will not obstruct the sunshade curtain, resulting in a significant sunshade effect and greater aesthetics.

[0068] While one or more embodiments of the present invention have been described above, those skilled in the art will recognize that the present invention can be implemented in any other form without departing from its spirit and scope. Therefore, the embodiments described above are illustrative and not restrictive, and many modifications and substitutions will be apparent to those skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
