[0002] With the development of the automotive industry and the continuous improvement of people's living standards, the diversification of automotive functions has become an important demand for users and a factor in their car purchase decisions. Currently, the field of automotive window dustproof nets is largely untapped, with few types available. Most car models on the market do not have dedicated dustproof devices for the front windows. When there is a lot of dust and fluff outside the car, opening the windows allows dust and fluff to enter the vehicle, polluting the interior environment. Therefore, the only way to avoid this is to close the windows, but closing the windows also leads to poor ventilation. Therefore, there is a need to invent an automotive window dustproof net device. Summary of the Invention

[0003] The purpose of this invention is to provide a dustproof net device for automobile windows, which solves the problem that existing models do not have a dedicated dustproof device on the front window, resulting in poor ventilation when the window is closed.

[0024] like Figures 1 to 4 The illustrated automotive window dustproof net device includes a triangular window housing 1, located at the triangular window position at the front of the A-pillar of the vehicle body. A coil 3 is rotatably connected to the triangular window housing 1, and a spring 4 is connected to the coil 3. When the coil 3 rotates, it causes the spring 4 to tighten or loosen. The coil 3 is fixedly connected to both ends of an elastic band 5. A dustproof net 6 is connected to the side wall of the elastic band 5. The elastic band 5 is arranged around the dustproof net 6. When the dustproof net 6 is fully opened, it can cover the size of the window frame. The elastic band 5 is a circular rubber band and is detachably connected to the side wall of the window frame.

[0025] To facilitate the winding up of the dustproof net 6 and the elastic band 5 during rotation, the winding reel 3 includes two sets of parallel limiting circular plates 31, with a winding drum 32 fixedly connected between the limiting circular plates 31. A central shaft 33 is provided in the winding reel 3, and the diameter of the limiting circular plates 31 is larger than the diameter of the winding drum 32. In this embodiment, both ends of the elastic band 5 are fixedly connected to the winding drum 32, either by injection molding or by using fixing clips on the winding drum 32 to snap the elastic band 5 into place.

[0026] In order to facilitate the rotatable connection of the winding reel 3 to the triangular window housing 1, a pivot hole 13 is provided on the side wall of the triangular window housing 1, and the spring 4 is sleeved on the central shaft 33, with one end of the central shaft 33 rotatably connected to the pivot hole 13.

[0027] To facilitate the fixing of both ends of the spring 4, a fixing groove 34 is provided at the other end of the central shaft 33. The inner end 41 of the spring 4 is snapped and fixedly connected to the fixing groove 34, and the outer end 42 of the spring 4 is snapped and fixedly connected to the triangular window cover plate 2 on one side of the triangular window housing 1. The triangular window cover plate 2 in the attached drawings of this embodiment is a schematic diagram when it is open. During assembly, the triangular window cover plate 2 needs to be fixed to the triangular window housing 1.

[0028] To facilitate the winding of the dustproof net 6 and the elastic band 5 onto the reel 3, a take-up groove 12 is provided on the rear side of the triangular window housing 1. The elastic band 5 and the dustproof net 6 can be wound onto the reel 3 through the take-up groove 12. In this embodiment, the take-up groove 12 can be configured as a waist-shaped groove.

[0029] In order to guide the winding and storage of the dustproof net 6 and the rubber band 5, a guide cover 11 is fixedly provided in the triangular window shell 1 at the position corresponding to the storage groove 12. The guide cover 11 has a smaller opening at the end closer to the storage groove 12 and a larger opening at the end farther away from the storage groove 12.

[0030] To facilitate pulling out the dustproof net 6 by hand, a handle 8 is fixedly connected to the rubber band 5.

[0031] To facilitate the installation and fixing of the handle 83, the handle component 8 includes a handle fixing part 81 that is fixedly connected to the rubber band 5, and the handle 83 is fixedly installed on the handle fixing part 81.

[0032] To prevent the dustproof net 6 and the rubber band 5 from being completely rolled into the triangular window housing 1, a limiting plate 82 is fixedly installed on the side wall of the handle fixing part 81, and the handle 83 is fixedly installed on the limiting plate 82. The width of the limiting plate 82 is greater than the width of the retraction groove 12. This structure ensures that the entire handle 83 will not enter the triangular window housing 1 through the retraction groove 12, thus making it easy to pull out the dustproof net 6 by hand.

[0033] To facilitate the dustproof net 6 being pulled out and secured to the window frame, several sets of buckles 7 are fixedly connected to the side wall of the window frame. The buckles 7 are spaced along the window frame and are used to engage with the rubber band 5.

[0034] This invention incorporates a storage mechanism at the triangular window position, comprising a triangular window housing 1, a triangular window cover 2, a winding reel 3, and a spring 4. When the dust net 6 needs to be retracted, the spring 4 automatically winds the dust net 6, along with the elastic band 5, onto the winding reel 3. When the dust net 6 needs to be opened, it can be pulled out directly using the handle 8 on the elastic band 5, and then manually fastened into the clips 7 around the window frame. A reasonable number of clips 7 ensures the dust net 6 is securely attached to the window frame. When the dust net 6 needs to be retracted, simply detach the elastic band 5 from the clips 7 and release; the elastic band 5 and dust net 6 will automatically retract into the triangular window housing 1.

[0035] The dustproof net 6 can be made of polytetrafluoroethylene (PTFE), which has excellent wear resistance, acid and alkali resistance, and high and low temperature resistance compared to traditional nylon netting. With a mesh size of 100 mesh or more and a hole diameter of 150um, it can protect against dust with a diameter of 150um or more, as well as most visible debris.
