Description

Technical Field

[0001] The invention relates to the technical field of sunshade curtains, and in particular to a sunshade curtain with a self-maintenance function. Background Art

[0002] Truck windshield sunshade film, also known as sunshade or sun visor, is a practical car accessory, especially in hot summer, the sunshade film can block most of the sunlight and reduce the temperature inside the car, so that the driver can enjoy a comfortable driving environment in hot summer. Long-term direct sunlight will accelerate the aging of the car interior. The sunshade film can effectively protect the interior from ultraviolet damage. The aluminum foil sunshade film has good reflective properties and can effectively block sunlight and heat. The common aluminum foil sunshade films on the market include double-sided silver aluminum film, patterned aluminum foil, etc., with various sizes, suitable for truck windshields of different sizes.

[0003] After using the existing sunshade for a period of time, the sunshade may not be able to be reset. At this time, the sunshade needs to be reset, which is very troublesome. Usually, if the sunshade cannot be reset, the outer shell, shaft, etc. of the sunshade need to be completely disassembled, or directly regarded as discarded and cannot be used again. In addition, the existing sunshade is fixed by the slots at both ends. The left side of the sunshade needs to be aligned with the left glass edge of the driver's seat, and the right side is usually fixed in the middle position of the truck glass. A driving recorder is often installed in this position, so the right installation position of the sunshade will conflict with the position of the driving recorder. In actual installation, the driving recorder needs to be removed, which is very inconvenient for users. The structure of the lower end of the sunshade film of the existing sunshade curtain is that the lower end of the sunshade film is wrapped with a long strip of fixing sheet, and the sunshade film is rolled up, and the fixing sheet is wrapped into the sunshade film with tape, and a hook is covered on the outside of the fixing sheet for fixing the sunshade curtain. Since the sunshade curtain is exposed to sunlight for a long time, the tape wrapped around the fixing sheet at the lower end of the sunshade film will crack and cannot be bonded. In this way, the fixing sheet will fall off from the sunshade film, resulting in the hook being unable to effectively fix the sunshade film, and also affecting the use effect of the sunshade curtain.

In addition, the existing sunshade film is fixed by the slots at both ends. The left side of the sunshade film needs to be aligned with the left glass edge of the driver's seat, and the right side is usually fixed in the middle position of the truck glass, and a driving recorder is often installed at this position, so the right side installation position of the sunshade film is It will conflict with the position of the driving recorder. In actual installation, the driving recorder needs to be removed, which is very inconvenient for users. The structure of the lower end of the existing sunshade film is that the lower end of the sunshade film is wrapped with a long strip-shaped fixing piece, and the sunshade film is rolled up, and the fixing piece is wrapped into the sunshade film with tape, and a hook with a horizontal component is slidably installed on the fixing piece to fix the sunshade film. Since the sunshade film is exposed to sunlight for a long time, the tape wrapped around the fixing piece at the lower end of the sunshade film will crack and cannot be bonded. In this way, the fixing piece will fall off the sunshade film, resulting in the hook being unable to effectively fix the sunshade film, and also affecting the use effect of the sunshade curtain.

[0023] An unlimited mounting slot 12 is provided on the outer wall of one end of the dustproof shell 11 away from the dustproof groove 13. The unlimited mounting slot 12 is T-shaped. An adjustment block 14 is movably inserted into the unlimited mounting slot 12. The adjustment block 14 is set to be in a T-shape that matches the unlimited mounting slot 12. A suction cup 15 is fixed at one end of the adjustment block 14.

[0024] The rotating shaft 33 movably passes through the circular groove 34 and is inserted in the winding drum 5. The plastic clamping plate 36 is movably clamped in the clamping groove 35. The outer wall of the rotating shaft 33 located in the connecting groove 38 is fixedly sleeved with a plastic clamping ring 37, and the plastic clamping ring 37 is movably inserted in the connecting groove 38.

[0025] A limiting slot 331 is provided at the end of the rotating shaft 33 away from the self-repair component 3, and a fixed sleeve 39 is slidably provided on the surface of the rotating shaft 33 close to the self-repair component 3. Four groups of limiting gear bars 30 are fixedly connected to the surface of the fixed sleeve 39. A torsion spring 4 is sleeved on the surface of the rotating shaft 33, and the torsion spring 4 is located in the inner cavity of the winding drum 5. One end of the torsion spring 4 passes through the limiting slot 331, and the other end of the torsion spring 4 is clamped and fixed to the surface of the four groups of limiting gear bars 30. The end of the winding drum 5 close to the self-repair component 3 is fixedly sleeved with the surface of the fixed sleeve 39. A positioning rod 51 is fixedly installed on one side of the inner cavity of the first fixed shell 2, and the positioning rod 51 extends to the inner cavity of one end of the winding drum 5 away from the end of the first fixed shell 2. The setting of the positioning rod 51 can be used to provide auxiliary support for one end of the winding drum 5 to ensure the normal rotation of the winding drum 5.

[0026] The winding drum 5 is located in the dustproof groove 13 .

[0027] The horizontal component 7 includes an adhesive plate 71 attached to the lower end of the sunshade film 6. A circular rail 72 is fixedly provided on one side of the adhesive plate 71. A clamping block 73 is movably inserted inside the circular rail 72. A hook 74 is fixedly provided at the lower end of the clamping block 73.

[0028] By setting an infinite installation slot 12, the position of the adjustment block 14 in the infinite installation slot 12 can be adjusted by sliding the adjustment block 14. The infinite installation slot 12 runs through the entire shell 11. During installation: the left side of the sunshade film 6 is aligned with the left side of the driver's seat. When the position of the installation suction cup 15 on the right side conflicts with the driving recorder, the suction cup 15 can move left or right along the infinite installation slot 12 to solve the problem of position conflict, so that the driving recorder does not need to be disassembled, the installation is more convenient, and the pasting is convenient.

When the sunshade film 6 needs to be unfolded, it is only necessary to pull the hook 74 downward along the windshield, and the sunshade film 6 is gradually unfolded as the winding drum 5 rotates, so that the winding drum 5 drives the fixing sleeve 39 to rotate, and then the torsion spring 4 fixed on the fixing sleeve 39 and the limit card slot 331 is deformed, contracted and tightened, and at the same time drives the rotating shaft 33 Rotation. When the sunshade film 6 completely covers the front windshield of the truck, it is only necessary to fix the hook 74 and the accessories on the dashboard. When the sunshade film 6 needs to be recovered, it is only necessary to cancel the fixation of the accessories on the dashboard of the hook 74, and then use the torsion spring 4 to generate a reverse torsional force to drive the winding drum 5 to rotate, thereby driving the sunshade film 6 to rise and gradually wrap around the surface of the winding drum 5. When the device is used for a long time, the torsional force of the torsion spring 4 may become loose. At this time, the sunshade film 6 cannot be completely retracted and wound onto the surface of the winding drum 5, thus causing the sunshade film 6 to be unable to be completely retracted. Then, the two groups of plastic card plates 36 can be driven to rotate on the inner side of the circular groove 34 by rotating the rotating shaft 33. Since the plastic card plate 36 is made of plastic material and has a certain deformation ability, the torsion spring 4 on the limiting card groove 331 at one end of the rotating shaft 33 can be synchronously driven to actively rotate and tighten, thereby driving the fixed sleeve 39 and the winding drum 5 to rotate, and then the excess end of the sunshade film 6 is wound onto the surface of the winding drum 5 for operation.

[0029] It should be understood that the purpose of these embodiments is only to illustrate the present invention and is not intended to limit the protection scope of the present invention.
