Description
Technical Field
[0001] This utility model belongs to the technical field of automotive air vent trim strips, specifically relating to an anti-detachment automotive air vent trim strip. Background Technology
[0002] Car vent trim strips can add rich color and texture to a car's interior, significantly enhancing its overall aesthetics and perceived quality. By choosing trim strips in different colors, materials, and designs, car owners can perfectly match them with other parts of the car's interior, creating a personalized cabin atmosphere. Installation is relatively simple; just align the trim strip with the vent and gently press or stick it on. However, for trim strips that require disassembly of interior components for installation, it is recommended to have them installed by a professional automotive mechanic to avoid damaging the interior parts.
[0003] However, since car air vent trim is located inside the car, the interior temperature gradually rises after the car is parked, causing the air vent trim to heat up as well. Because many car air vent trims are currently made of plastic, and plastic has a low density, its heat dissipation efficiency is reduced. This means that when the air vents blow air, they cannot effectively dissipate the heat inside the trim, leaving it at a high temperature for extended periods, which accelerates its aging process. Utility Model Content
[0004] The purpose of this invention is to provide an anti-detachment automotive air vent trim strip, aiming to solve the problem that existing automotive air vent trim strips are located in the car's interior environment. When the car is parked, the interior temperature gradually rises, causing the temperature of the air vent trim strip to rise as well. Since many current automotive air vent trim strips are made of plastic, and plastic has a low density, this results in reduced heat dissipation efficiency. Consequently, when the air vents are blowing air, they cannot effectively dissipate the heat inside the trim strip, leaving it at a high temperature for extended periods, thus accelerating its aging process.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-detachment type automotive air vent trim strip, comprising a U-shaped frame and a first fixed frame and a second fixed frame integrally connected at the ends of the U-shaped frame, anti-slip pads are installed on the corresponding side walls of the first fixed frame and the second fixed frame, and anti-slip protrusions are installed at the ends of the anti-slip pads. Grooves are formed on the inner walls of the U-shaped frame, the first fixed frame and the second fixed frame, and heat dissipation holes are formed through the surface of the U-shaped frame. A dustproof net is connected to the end of the groove.
[0006] Preferably, as an anti - detachment automotive air outlet trim of the present utility model, the anti - slip pad is in a "human" shape, and there are two anti - slip pads.
[0007] Preferably, as an anti - detachment automotive air outlet trim of the present utility model, there are three anti - slip ridges.
[0008] Preferably, as an anti - detachment automotive air outlet trim of the present utility model, there are twenty grooves, which are evenly distributed on the inner walls of the U - shaped frame, the first fixed frame and the second fixed frame.
[0009] Preferably, as an anti - detachment automotive air outlet trim of the present utility model, the groove is in a "U" shape.
[0010] Preferably, as an anti - detachment automotive air outlet trim of the present utility model, the heat dissipation holes are in a horn shape and are connected to the grooves.
[0011] Preferably, as an anti - detachment automotive air outlet trim of the present utility model, the dustproof net is made of nylon material.
[0012] Compared with the prior art, the beneficial effects of the present utility model are:
[0013] By opening grooves and heat dissipation holes on the automotive air outlet trim, when the trim is connected to the blades of the automotive air outlet and the vehicle starts and the air outlet starts to blow air, the air flow will flow along the grooves and be discharged through the heat dissipation holes. This collaborative design of the grooves and heat dissipation holes can significantly reduce the temperature of the trim itself and effectively reduce the damage caused by high temperature to the trim material.
[0014] By using the dustproof net, when the vehicle starts and the air outlet starts to blow air, the dust carried in the air flow will be effectively blocked by the dustproof net. This design can prevent dust from clogging the channels of the grooves and heat dissipation holes, thus ensuring the normal functioning of the heat dissipation function and preventing the trim from softening, deforming, etc. due to poor heat dissipation, and maintaining its good state and performance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-6 This utility model provides the following technical solution: a car air vent trim strip with anti-detachment feature, comprising a U-shaped frame 1 and a first fixed frame 2 and a second fixed frame 3 integrally connected to the ends of the U-shaped frame 1. Anti-slip pads 4 are installed on the corresponding side walls of the first fixed frame 2 and the second fixed frame 3. Anti-slip protrusions 5 are installed at the ends of the anti-slip pads 4. Grooves 6 are formed on the inner walls of the U-shaped frame 1, the first fixed frame 2, and the second fixed frame 3. Heat dissipation holes 7 are formed through the surface of the U-shaped frame 1. Dustproof nets 8 are connected to the ends of the grooves 6. The anti-slip pads 4 are herringbone shaped and have two layers. The anti-slip protrusions 5 have three layers.
[0025] In practical use, the car air vent trim consists of a U-shaped frame 1, a first fixed frame 2, and a second fixed frame 3. During installation, the installer simply clips the trim onto the air vent blades to complete the assembly. After assembly, the anti-slip pads 4 and anti-slip protrusions 5 on the trim will tightly engage with the air vent blades, creating a counteracting effect and effectively enhancing the anti-detachment performance between the air vent trim and the blades.
[0026] It is worth noting that the U-shaped frame 1, the first fixed frame 2, and the second fixed frame 3 are made of plastic.
[0027] Preferably, twenty grooves 6 are evenly spaced on the inner walls of the U-shaped frame 1, the first fixed frame 2, and the second fixed frame 3. The grooves 6 are U-shaped. The heat dissipation holes 7 are funnel-shaped and connected to the grooves 6. The dustproof mesh 8 is made of nylon.
[0028] In practical use, once the car's air vent trim is connected to the air vent blades, and the car is started and air begins to flow from the vents, the airflow will follow the groove 6 and be discharged through the heat dissipation hole 7. The groove 6 and the heat dissipation hole 7 work together to significantly reduce the temperature of the trim itself, effectively reducing the damage caused by high temperatures to the trim material.
[0029] Meanwhile, when the car starts and air is vented, dust carried in the airflow is effectively intercepted by the dust filter 8. This design prevents dust from clogging the channels of the groove 6 and the heat dissipation holes 7, ensuring the normal operation of the heat dissipation function and preventing the trim strip from softening or deforming due to poor heat dissipation, thus maintaining its good condition and performance.
[0030] Of particular note is that the heat dissipation vent 7 is designed in a trumpet shape, a unique shape that helps reduce noise generated during airflow.
[0031] Working principle: When installing the car air vent trim, the installer simply needs to precisely clip the trim onto the air vent blades to easily complete the assembly process. After successful assembly, the carefully designed anti-slip pads 4 and anti-slip protrusions 5 on the trim will fit tightly against the air vent blades, creating a stable counterforce. This design effectively enhances the anti-detachment performance between the air vent trim and the blades, ensuring the trim remains firmly in place even during vehicle travel, preventing loosening or detachment.
[0032] Once the car's air vent trim is securely connected to the air vent blades, and the car is started and the vents begin to vent normally, the airflow will smoothly follow a specific path along the groove 6 and ultimately exit through the heat dissipation hole 7. The groove 6 and the heat dissipation hole 7 work together to create an efficient heat dissipation channel, significantly reducing the trim's own temperature. In high-temperature environments, this effectively reduces damage to the trim material caused by high temperatures, preventing material aging and performance degradation due to prolonged exposure to high temperatures, thus extending the trim's lifespan.
[0033] Meanwhile, during car startup and airflow from the vents, some dust inevitably gets trapped in the airflow. However, thanks to the dust filter 8, this dust is effectively trapped. This design is crucial, preventing dust from clogging the channels of the recess 6 and the vents 7, ensuring continuous and normal heat dissipation. If dust clogs the channels, the heat dissipation effect will be greatly reduced, and the trim strips can easily soften or deform due to poor heat dissipation, affecting their appearance and normal use. With the protection of the dust filter 8, the trim strips can always maintain their good condition and performance, creating a more comfortable and aesthetically pleasing environment inside the car.
[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
