Description

Technical Field

[0001] The utility model relates to the field of automobile production, in particular to an aging-resistant, high-insulation, externally-attached automobile skylight protective film. Background Art

[0002] With the rapid development of the automobile industry and the increasing diversification of consumer demand, car sunroofs have been widely used in various types of vehicles as an important configuration to improve driving comfort and viewing experience. However, as a large-area glass structure, the car sunroof is exposed to the external environment, especially under high temperature and strong ultraviolet radiation conditions, and is easily affected by aging and thermal radiation, resulting in increased temperature inside the car, affecting the driving experience, and may accelerate the aging of the interior decorative materials. Therefore, it is particularly important to develop an aging-resistant, high-insulation car sunroof protective film that is resistant to aging and has high heat insulation.

[0003] Currently, there are a variety of car sunroof insulation measures on the market, mainly including internal insulation film and external insulation materials. Among them, the insulation film material mainly uses insulation material to make a thin film, which is installed on the sunroof to block sunlight and prevent sunlight from shining into the car through the sunroof, causing the temperature to rise.

[0004] However, these products have limited insulation effects to varying degrees. Some internal insulation films achieve insulation effects mainly by absorbing infrared rays, but they are easily saturated and may produce secondary radiation, affecting the durability of insulation performance and have poor aging resistance. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an aging-resistant, high-insulation, external automobile sunroof protective film to solve the problems of existing products to varying degrees. The heat insulation effect is limited. Some internal heat insulation films mainly achieve the heat insulation effect by absorbing infrared rays, but are easily saturated and may produce secondary radiation, affecting the durability of the heat insulation performance and having poor aging resistance.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aging-resistant shell heat-insulating external automobile sunroof protective film, comprising a first TPU shell, a heat-insulating film is arranged between the first TPU shell and the second TPU shell, a mounting strip is arranged on one side of the heat-insulating film, the mounting strip extends upward for a section, and a groove is provided on one side of the mounting strip close to the mounting strip.

[0007] By adopting the above technical solution, the first TPU shell and the second TPU shell are arranged outside the thermal insulation film to protect the thermal insulation film and prevent the thermal insulation film from directly contacting the outside world, thereby ensuring the long-term use of the thermal insulation film.

[0008] The utility model is further configured such that a through groove is provided on a surface of the first TPU shell and the second TPU shell close to the thermal insulation film.

[0009] By adopting the above technical solution, a certain distance is ensured between the outer shell and the thermal insulation film by means of the provided through groove, thereby ensuring the thermal insulation effect of the protective film.

[0010] The utility model is further configured that an air exchange cavity is opened in the mounting strip in coordination with the through groove, a wheel fan is arranged in the air exchange cavity, a rotating shaft is arranged in the air exchange cavity in coordination with the wheel fan, and the wheel fan rotates through the rotating shaft.

[0011] By adopting the above technical solution, the wheel fan is set to drive the air circulation in the slot when the wheel fan rotates, thereby cooling the slot, improving the insulation effect of the insulation film, and ensuring the service life of the protective film.

[0012] The utility model is further configured that an exhaust hole is provided on a surface of the installation strip away from the heat insulation film to cooperate with the air exchange cavity.

[0013] By adopting the above technical solution, the air flow in the mounting strip is ensured through the exhaust holes, thereby achieving the air flow in the mounting strip.

[0014] The utility model is further configured that a connecting cavity is provided in the mounting strip in cooperation with the slot, a connecting channel is provided in the mounting strip in cooperation with the connecting cavity, and the connecting channel is connected to the air exchange cavity.

[0015] By adopting the above technical solution, the air entering from the slot is ensured to be discharged from the exhaust hole through the connecting channel, thereby achieving the cooling of the thermal insulation film.

[0016] The utility model is further configured that an adhesive strip is provided at the bottom of the installation strip.

[0017] By adopting the above technical solution, the installation strip is installed through the adhesive strip, and then the protective film is installed.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] The utility model installs the installation strip to one side of the sunroof through the adhesive strip. At this time, the protective film is attached to the sunroof, and the slotted opening is aligned with the forward direction of the vehicle. In daily use, a certain interval is ensured between the TPU shell and the thermal insulation film through the connecting cavity to ensure the thermal insulation effect. Thereafter, when the vehicle is driving, the gas enters the installation strip through the slot, drives the wheel fan to rotate, drives the air in the connecting cavity to circulate, effectively takes away the heat, and increases the service life of the protective shell.
