Description

Technical Field

[0001] This utility model relates to the field of sunshade device technology, and in particular to a swing arm awning. Background Technology

[0002] Awnings are a common type of sunshade device, widely used in hotels, office buildings, and other places. They effectively block strong sunlight without affecting the view from windows, and can also beautify the building's appearance, regulate indoor lighting, and improve the quality of life. Awnings control the angle at which the awning fabric unfolds by rotating a swing arm. Currently, the maximum rotation angle of the swing arm in existing awnings is usually fixed. This means that when the awning is fully unfolded, either the awning is parallel to the wall to completely cover doors and windows, or the awning is at a certain angle to the wall to leave a gap. However, in reality, different installation conditions and varying user needs make this fixed maximum rotation angle design insufficient to meet usage requirements, necessitating optimization. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to design a swing arm canopy that can adjust the maximum rotation angle of the swing arm to adapt to installation and usage requirements.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] Design a swing arm awning, including a base, an awning cloth, and a roller rotatably mounted on the base. One end of the awning cloth is fixedly connected to the roller, and the other end of the awning cloth is provided with a fixing plate. The fixing plate is provided with swing arm mechanisms on both sides in the length direction. The swing arm mechanism includes a fixed seat, a swing arm mounted on the fixed seat, and an angle adjustment unit. The swing arm includes a hinge seat and a connecting seat. The connecting seat is connected to the fixing plate, and the hinge seat is rotatably connected to the fixed seat. The angle adjustment unit can abut against the hinge seat to limit the maximum rotation angle of the swing arm. Adjusting the angle adjustment unit can change the maximum rotation angle of the swing arm.

[0006] This design features a swing-arm awning installed outside doors and windows, effectively blocking strong sunlight. The awning fabric is rolled up on a roller. When unfolding, the roller is rotated to release the fabric, which then unfolds and descends under the drive of the swing-arm mechanism, forming a certain angle with the doors and windows during the unfolding process. When retracting, the roller is rotated to retract the fabric, which then drives the swing-arm to rotate and close to the doors and windows. The adjustable swing-arm rotation angle enhances the flexibility and adaptability of the awning's installation layout. Through the contact mechanism between the angle adjustment unit and the hinged base, users can freely adjust the maximum rotation angle of the swing arm according to actual needs, such as shading area and wind resistance. The maximum rotation angle is 180°, meeting the requirements of different climate conditions and site layouts. The swing-arm mechanism uses a rotating connection between the hinged base and the fixed base, which can disperse stress through small swings when wind force changes, reducing structural rigidity impact and improving wind resistance.

[0007] Furthermore, the angle adjustment unit includes a limiting block rotatably mounted on the fixed base and an adjusting nut movably mounted on the fixed base. One end of the adjusting nut abuts against the surface of the limiting block, and turning the adjusting nut can drive the limiting block to rotate.

[0008] The screw drive design of the adjusting nut and the limiting block enables continuous angle adjustment. Specifically, the limiting block is rotatably mounted on a fixed base via a pin. The fixed base has a through hole with a thread on its inner wall that matches the adjusting nut. One end of the adjusting nut extends out of the through hole and abuts against the surface of the limiting block. Tightening the adjusting nut allows the end abutting against the surface of the limiting block to move axially, thereby driving the limiting block to rotate and change its position to adjust the maximum rotation angle of the swing arm. Furthermore, both the limiting block and the adjusting nut can be disassembled individually, and if either fails, it can be replaced separately without replacing the entire fixed base, thus reducing maintenance costs.

[0009] Furthermore, the angle adjustment unit also includes a first elastic element located between the limiting block and the fixed seat, the first elastic element driving the limiting block to abut against the adjusting nut.

[0010] The first elastic element is a torsion spring, with its two ends abutting against the fixed seat and the limiting block, respectively. The spring force keeps the end of the adjusting nut in contact with the limiting block, ensuring no play during angle adjustment. Furthermore, the preload of the first elastic element and the self-locking thread of the adjusting nut form a dual anti-loosening mechanism, maintaining the angle locked state even under vibration conditions. Compared to a pure thread structure, this improves the resistance to loosening.

[0011] Furthermore, the fixing seat is provided with a receiving groove for accommodating the first elastic member.

[0012] The receiving groove limits the first elastic element through the side wall, forming a positional constraint to ensure that the compression direction of the first elastic element is relatively parallel to the force axis of the adjusting nut, thus avoiding the dispersion of preload caused by off-center loading.

[0013] Furthermore, the fixing base includes baffles located on both sides in its width direction, and the limiting block is provided with a retaining groove that cooperates with the baffles.

[0014] The combination of the baffle and the baffle groove forms a "lateral + longitudinal" dual constraint. When the swing arm is at its maximum rotation angle, the baffle groove and the baffle are pressed together, forming a limiting and stabilizing structure.

[0015] Furthermore, the swing arm also includes a hollow connecting rod, with the hinge seat and the connecting seat respectively inserted at both ends of the connecting rod.

[0016] The connecting rod is made of a suitable material to meet the rigidity requirements of the swing arm under dynamic loads, while also considering lightweight design and mechanical performance. The hinge and connecting seat use a pin-positioning assembly structure, which allows for quick installation and disassembly, improving assembly efficiency.

[0017] Furthermore, at least one of the swing arm mechanisms is provided with an elastic unit, which includes a second elastic element and a pull rope. One end of the second elastic element is connected to the connecting seat, and the other end is connected to the fixed seat through the pull rope.

[0018] The second elastic element is a tension spring. When the roller retracts the tarpaulin, the tension spring is stretched to form elastic potential energy. When the roller releases the tarpaulin and unfolds it, the elastic potential energy of the tension spring is gradually released so that the tarpaulin can be unfolded smoothly and tightened, avoiding wrinkles and improving its wind resistance.

[0019] Furthermore, the second elastic element is located within the hollow cavity of the connecting rod.

[0020] The second elastic element is hidden inside the cavity of the connecting rod, allowing the elastic force to be transmitted directly along the axis of the rod, eliminating the lever arm loss of traditional external structures, and making the appearance simpler and more beautiful.

[0021] Furthermore, the fixing base is provided with a connecting block connected to the pull rope, and the surface of the connecting block is provided with a groove that fits into the pull rope.

[0022] The pull rope is a loop rope, with one end placed in the hollow cavity of the connecting rod and hooked to the hook at the end of the second elastic element. The other end passes through the hinge seat, the limiting block and hooked to the connecting block. The connecting block has a groove on its periphery, and the pull rope is fitted into the groove to ensure that it does not fall off.

[0023] Furthermore, it also includes a drive motor that can drive the reel to rotate to wind up or unwind the tarpaulin.

[0024] The drive motor is a reel motor, which is installed inside the reel to ensure a clean overall appearance. The controller controls the forward and reverse rotation of the drive motor to drive the reel to rotate, thereby enabling the tarpaulin to be rolled up or unrolled.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This design features a swing-arm awning installed outside doors and windows, effectively blocking strong sunlight. The awning fabric is rolled up on a roller. When unfolding, the roller is rotated to release the fabric, which then unfolds and descends under the drive of the swing-arm mechanism, forming a certain angle with the doors and windows during the unfolding process. When retracting, the roller is rotated to retract the fabric, which then drives the swing-arm to rotate and close to the doors and windows. The adjustable swing-arm rotation angle enhances the flexibility and adaptability of the awning's installation layout. Through the contact mechanism between the angle adjustment unit and the hinged base, users can freely adjust the maximum rotation angle of the swing arm according to actual needs, such as shading area and wind resistance. The maximum rotation angle is 180°, meeting the requirements of different climate conditions and site layouts. The swing-arm mechanism uses a rotating connection between the hinged base and the fixed base, which can disperse stress through small swings when wind force changes, reducing structural rigidity impact and improving wind resistance.

[0032] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0033] like Figure 1 and Figure 2 As shown, this embodiment provides a swing-arm awning, which is installed on the upper edge of a door or window. It includes a base 1, an awning fabric 2, and a roller 3 rotatably mounted on the base 1. The base 1 can be fixed to the wall with rivets. One end of the awning fabric 2 is fixedly connected to the roller 3, and the other end of the awning fabric 2 is provided with a fixing plate 4. Swing-arm mechanisms 5 are provided on both sides of the fixing plate 4 along its length. A drive motor (not shown in the figure) is installed inside the roller 3 to ensure a simple overall appearance. The drive motor is a roller motor, and the controller controls the forward and reverse rotation of the drive motor to drive the roller 3 to rotate, thereby achieving the winding or unwinding of the awning fabric 2. The swing-arm mechanism 5 includes a fixed base 51, a swing arm 52 mounted on the fixed base 51, and an angle adjustment unit 53. The fixed base 51 is vertically mounted on the wall. The swing arm 52 includes a hollow connecting rod 523, a hinge seat 521, and a connecting seat 522. The hinge seat 521 and the connecting seat 522 are respectively inserted into both ends of the connecting rod 523. The connecting rod 523 is made of a suitable material to meet the rigidity requirements of the swing arm 52 under dynamic load, while also considering lightweight and mechanical performance. The joint ends of the hinge seat 521 and the connecting seat 522 adopt a pin-positioning assembly structure, which can realize quick installation and disassembly, and improve assembly efficiency. The connecting seat 522 is detachably connected to the fixing plate 4. The fixing seat 51 has a hinge joint at one end near the hinge seat 521. The hinge seat 521 is hinged to the hinge joint. The angle adjustment unit 53 can abut against the hinge seat 521 to limit the maximum rotation angle of the swing arm 52. Adjusting the angle adjustment unit 53 can change the maximum rotation angle of the swing arm 52.

[0034] like Figure 3 and Figure 4As shown, the angle adjustment unit 53 includes a limiting block 531 rotatably mounted on a fixed base 51, an adjusting nut 532 movably mounted on the fixed base 51, and a first elastic member 533 located between the limiting block 531 and the fixed base 51. The fixed base 51 has a receiving groove 511, and the first elastic member 533 is disposed in the receiving groove 511. The receiving groove 511 limits the first elastic member 533 through its side wall, forming a positional constraint to ensure that the compression direction of the first elastic member 533 is relatively parallel to the force application axis of the adjusting nut 532, avoiding the dispersion of preload caused by off-center loading. The first elastic member 533 drives the limiting block 531 to abut against one end of the adjusting nut 532. Tightening the adjusting nut 532 can drive the limiting block 531 to rotate. The helical drive design of the adjusting nut 532 and the limiting block 531 enables continuous angle adjustment. Specifically, the limiting block 531 is rotatably mounted on the fixed seat 51 via a pin. The fixed seat 51 has a through hole with a thread matching the adjusting nut 532 on its inner wall. One end of the adjusting nut 532 extends out of the through hole. The first elastic element 533 is a torsion spring, with both ends of the torsion spring abutting against the fixed seat 51 and the limiting block 531, respectively. The spring force of the torsion spring ensures that the end of the adjusting nut 532 is always in contact with the limiting block 531, ensuring no backlash during angle adjustment. Tightening the adjusting nut 532 allows the end abutting against the surface of the limiting block 531 to move axially, thereby driving the limiting block 531 to rotate and change its position to adjust the maximum rotation angle of the swing arm 52. Furthermore, the preload of the first elastic element 533 and the self-locking thread of the adjusting nut 532 form a double anti-loosening mechanism, maintaining the angle locked state even under vibration conditions. Compared to a pure thread structure, this improves the resistance to loosening. Meanwhile, both the limit block 531 and the adjusting nut 532 can be disassembled separately, and either one can be replaced if it fails, without having to replace the entire mounting base, thus reducing maintenance costs.

[0035] like Figure 2 and Figure 3As shown, the swing arm mechanism 5 is equipped with an elastic unit 54. One or two elastic units 54 can be provided. Each elastic unit 54 includes a second elastic element 541 and a pull rope 542. The second elastic element 541 is a tension spring, with hooks at both ends. The connecting seat 522 has a hook groove for hook engagement, and the other end is connected to the fixed seat 51 via the pull rope 542. Specifically, the fixed seat 51 has a connecting block 513 connected to the pull rope 542. The surface of the connecting block 513 has a groove 5131 that fits into the pull rope 542. The pull rope 542 is a loop rope. One end is placed in the hollow cavity of the connecting rod 523 and hooked to the hook at the end of the second elastic element 541. The other end passes through the hinge seat 521 and the limiting block 531 and hooks into the connecting block 513. The connecting block 513 has a groove 5131 on its periphery, and the pull rope 542 is fitted into the groove 5131 to prevent it from falling off. The second elastic element 541 is hidden inside the cavity of the connecting rod, allowing the elastic force to be transmitted directly along the rod axis, eliminating the lever arm loss of traditional external structures, and making the appearance simpler and more aesthetically pleasing. When the roller 3 retracts the tarpaulin 2, the tension spring is stretched to form elastic potential energy. When the roller 3 releases the tarpaulin 2 to unfold, the elastic potential energy of the tension spring is gradually released, so that the tarpaulin 2 unfolds smoothly and is tightened, avoiding wrinkles and improving its wind resistance.

[0036] In addition, the swing-arm awning in this embodiment can also be equipped with a light sensing unit and a rain sensing unit. By collecting the light intensity, the light intensity signal is transmitted to the controller, and the light intensity is used to control the automatic unfolding, retraction, and opening and closing angle of the curtain. The rain sensing unit monitors whether it is raining, and when rain is detected, the signal is transmitted to the controller to control the curtain to automatically retract.

[0037] This embodiment of the swing-arm awning is installed outside doors and windows, effectively blocking strong sunlight. The awning fabric 2 is rolled up on a roller 3. When it needs to be unfolded, the roller 3 is rotated to release the awning fabric 2, which unfolds and descends under the drive of the swing-arm mechanism 5, forming a certain angle with the doors and windows during the unfolding process. When it needs to be retracted, the roller 3 is rotated to retract the awning fabric 2, which drives the swing arm 52 to rotate and move closer to the doors and windows. The adjustable rotation angle of the swing arm 52 improves the flexibility and adaptability of the swing-arm awning installation layout. Through the contact mechanism between the angle adjustment unit 53 and the hinge seat 521, the user can freely adjust the maximum rotation angle of the swing arm 52 according to actual needs, such as shading area and wind resistance. The maximum rotation angle is 180°, meeting the needs of different climate conditions and site layouts. The swing-arm mechanism 5 adopts a rotating connection between the hinge seat 521 and the fixed seat 51, which can disperse stress through small swings when the wind changes, reduce the impact on structural rigidity, and improve wind resistance performance.
