Description

Technical Field

[0001] This utility model relates to the field of sunshade curtain technology, and in particular to a sunshade curtain with self-maintenance function. Background Technology

[0002] Truck windshield sunshade film, also known as sun visor or sun shield, is a practical automotive accessory. Especially in the hot summer, sunshade film can block most of the sunlight, reduce the interior temperature, and allow the driver to enjoy a comfortable driving environment even in hot summer. Prolonged direct sunlight can accelerate the aging of the car interior. Sunshade film can effectively protect the interior from ultraviolet damage. Aluminum foil sunshade film has good reflective properties and can effectively block sunlight and heat. Common aluminum foil sunshade films on the market include double-sided silver aluminum film, patterned aluminum foil, etc., in various sizes to suit different sizes of truck windshields.

[0003] After a period of use, existing sunshades may become unable to reset, which is very troublesome. Usually, if the sunshade cannot be reset, the entire outer shell and hinges of the sunshade need to be disassembled, or it can be considered unusable. In addition, existing sunshades are fixed by slots at both ends. The left side of the sunshade needs to be aligned with the left edge of the driver's side window, while the right side is usually fixed in the middle of the truck window. This position is often where a dashcam is installed, so the installation position of the right side of the sunshade will conflict with the position of the dashcam. In actual installation, the dashcam needs to be removed, which is very inconvenient for the user. The existing structure of the lower end of the sunshade film in sunshade curtains is as follows: the lower end of the sunshade film is wrapped with a long strip-shaped fixing piece, and the sunshade film is rolled up. The fixing piece is wrapped in the sunshade film with tape. The fixing piece has hooks on the outside for fixing the sunshade curtain. Because the sunshade curtain 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 stick. As a result, the fixing piece will come out of the sunshade film, making it impossible for the hooks to effectively fix the sunshade film, which also affects the use effect of the sunshade curtain. Utility Model Content

[0004] Specifically, the technical problem this utility model aims to solve is to provide a sunshade with a self-maintenance function, addressing the issue that existing sunshade films often fail to reset after a period of use. This necessitates disassembling the film, which is inconvenient. Typically, if a sunshade cannot reset, it is considered unusable. Furthermore, existing sunshade films are fixed using slots at both ends. The left side of the sunshade needs to be aligned with the left edge of the driver's side window, while the right side is usually fixed in the middle of the truck window. This location is often where a dashcam is installed, so the right side of the sunshade will be incompatible with the driver's side window. The location of the dashcam conflicts with the actual installation, requiring the dashcam to be removed, which is very inconvenient for users. Existing sunshade films have a structure where a long strip of fixing sheet is wrapped around the bottom of the film, and the film is rolled up. The fixing sheet is then wrapped with tape and a hook with a horizontal component is slidably mounted on the fixing sheet to secure it. However, due to prolonged exposure to sunlight, the tape wrapping the fixing sheet at the bottom of the film cracks and fails to adhere, causing the fixing sheet to detach from the film. This prevents the hook from effectively securing the film and affects the sunshade's performance. This invention addresses this problem.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sunshade curtain with self-maintenance function, including a shell, the shell including a dustproof shell, one end of the dustproof shell being connected to a first fixed shell, the end of the dustproof shell away from the first fixed shell being connected to a self-maintenance component, the self-maintenance component including a second fixed shell disposed at the end of the dustproof shell away from the first fixed shell, a fixed bushing fixedly disposed in the middle of the second fixed shell, a circular groove being formed on the fixed bushing, a communicating groove being formed inside the fixed bushing, and the communicating groove and the circular groove being interconnected, a rotating shaft being inserted in the circular groove, two sets of mutually symmetrical slots being formed in the middle of the circular groove, two sets of mutually symmetrical plastic plates being provided on the rotating shaft, a winding drum being disposed between the first fixed shell and the second fixed shell, and the rotating shaft extending into the inner cavity of the winding drum, a sunshade film being wrapped around the outer wall of the winding drum, and a horizontal component being connected to the lower end of the sunshade film.

[0028] The outer wall of the dust cover 11 away from the dust cover groove 13 has an unlimited mounting slot 12. An adjustment block 14 is movably inserted into the unlimited mounting slot 12. A suction cup 15 is fixedly provided at one end of the adjustment block 14.

[0029] The rotating shaft 33 moves through the circular groove 34 and is inserted into the take-up drum 5. The plastic clamp 36 is movably engaged in the clamp groove 35. A plastic retaining ring 37 is provided at the end of the rotating shaft 33 away from the plastic clamp 36. The plastic retaining ring 37 is movably engaged in the connecting groove 38.

[0030] A limiting groove 331 is provided at the end of the rotating shaft 33 away from the self-maintenance component 3. A fixing sleeve 39 is slidably provided on the surface of the rotating shaft 33 near the self-maintenance component 3. Four sets of limiting bars 30 are fixedly connected to the surface of the fixing sleeve 39. A torsion spring 4 is sleeved on the surface of the rotating shaft 33 and is located in the inner cavity of the take-up drum 5. One end of the torsion spring 4 passes through the limiting groove 331 and the other end of the torsion spring 4 is snapped and fixed to the surface of the four sets of limiting bars 30. The end of the take-up drum 5 near the self-maintenance component 3 is fixedly sleeved with the surface of the fixing sleeve 39. A positioning rod 51 is fixedly installed on one side of the inner cavity of the first fixing shell 2, and the end of the positioning rod 51 away from the first fixing shell 2 extends to the inner cavity of one end of the take-up drum 5. The positioning rod 51 can be used to provide auxiliary support for one end of the take-up drum 5 to ensure the normal rotation of the take-up drum 5.

[0031] The winding drum 5 is located inside the dustproof groove 13.

[0032] The adjusting block 14 is configured to be T-shaped to cooperate with the unlimited mounting slot 12, and the cross-section of the unlimited mounting slot 12 is T-shaped.

[0033] The horizontal component 7 includes an adhesive plate 71 that is 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 locking block 73 is movably inserted into the circular rail 72. A hook 74 is fixedly provided at the lower end of the locking block 73.

[0034] By setting an infinite mounting slot 12 and adjusting the position of the sliding adjustment block 14 within the infinite mounting slot 12, the infinite mounting slot 12 extends through the entire housing 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 right-side mounting suction cup 15 conflicts with the dashcam, the suction cup 15 can move left or right along the infinite mounting slot 12 to resolve the position conflict, thus eliminating the need to disassemble the dashcam and making installation more convenient. The adhesive plate 71 is glued to the lower end of the sunshade film 6, which solves the problem that the tape wrapping the fixing piece at the lower end of the sunshade film will crack and fail to adhere after long-term exposure to sunlight. When it is necessary to unfold the sunshade film 6, simply pull the hook 74 down along the windshield. The sunshade film 6 gradually unfolds as the winding drum 5 rotates, causing the winding drum 5 to rotate the fixing sleeve 39, which is then fixed to the fixing sleeve 39 and the limiting slot 331. The torsion spring 4 on the top deforms and contracts, tightening and simultaneously rotating the shaft 33. Once the sunshade film 6 completely covers the truck's windshield, simply secure the hook 74 and the accessories on the dashboard. When retracting the sunshade film 6, simply unsecure the hook 74 and the accessories on the dashboard. Then, the torsion spring 4 generates a reverse torsional force, rotating the take-up drum 5. This causes the sunshade film 6 to rise and gradually wrap around the surface of the take-up drum 5. With prolonged use, the torsion force of the torsion spring 4 may loosen, preventing the sunshade film 6 from fully retracting and wrapping around the surface of the take-up drum 5. This results in the sunshade film 6 not being fully retracted. To resolve this, the shaft 33 can be turned, causing the two sets of plastic clamps 36 to rotate inside the circular groove 34. Since the plastic clamps 36 are made of plastic, they have a certain deformation capacity, which simultaneously drives the torsion spring 4 on the limiting groove 331 at one end of the shaft 33. Active rotation tightening is performed, which in turn drives the fixed sleeve 39 and the take-up drum 5 to rotate, and then the excess end of the sunshade film 6 is wound up to the surface of the take-up drum 5.
