Abstract
Description
Technical Field
[0001] This utility model relates to the field of trim technology, specifically to an anti-ultraviolet polymer trim for the roof of a new energy vehicle. Background Technology
[0002] Trim strips are important protective and decorative components for new energy vehicles. They can fill various gaps and crevices between the components of the vehicle's roof and are generally placed inside the drainage channel. While improving the sealing between the drainage channel and the outside world, trim strips also help with shock absorption, waterproofing, dustproofing, and sound insulation, thereby improving the comfort of the driving experience and protecting the vehicle body from external environmental damage.
[0003] The existing trim strips have a single-channel drainage design, which results in a wide channel and a slow water flow, leading to a weak sand-carrying capacity and a tendency for sand and gravel to accumulate. Existing flat cross-section or simple curved design trim strips cannot improve the wind resistance of the roof. Therefore, a UV-resistant polymer trim strip for the roof of new energy vehicles is proposed. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides an anti-ultraviolet polymer trim strip for the roof of new energy vehicles.
[0005] The technical solution adopted by this utility model to solve its technical problem is an anti-ultraviolet polymer trim strip for the roof of a new energy vehicle, which includes a trim strip, the trim strip including a top piece, a W-shaped water guide piece, a buckle and a wind-breaking fin structure;
[0006] The W-shaped water guide plate is integrally connected to the bottom of the top plate, the buckle is integrally connected to both ends of the bottom of the top plate, and the wind-breaking fin structure is set on the top of the top plate.
[0007] By adopting the above technical solution, a set of UV-resistant trim strips is provided for the water channels on both sides of the roof of new energy vehicles through a trim strip composed of a top plate, a W-shaped water guide plate, a buckle and a wind-breaking fin structure. The wind-breaking fin structure improves the wind-breaking effect of the roof during driving, splits high-speed airflow, and reduces turbulence on the roof.
[0008] Specifically, a first water-guiding groove is formed between the top plate and the W-shaped water-guiding lower plate, and a second water-guiding groove is formed at the bottom center of the W-shaped water-guiding lower plate.
[0009] By adopting the above technical solution, through the setting of the W-shaped water guide plate, the two sets of first water guide grooves formed at both ends of the W-shaped water guide plate, and the second water guide groove formed at the bottom of the W-shaped water guide plate, three independent drainage channels are formed between the top plate and the water guide groove of the car roof. The three independent drainage channels can reduce the probability of blockage during the drainage process. Compared with the traditional setting of a single drainage channel concentrated in the middle, even if one or two of the three drainage channels in this application are blocked by dust accumulation, there are still drainage channels for rainwater to drain. Moreover, since all three drainage channels are open structures, they can be easily cleaned after the trim strip is removed from the drainage groove of the roof, greatly increasing the convenience of later maintenance and use.
[0010] Specifically, the wind-breaking fin structure includes fin-shaped protrusions, the front end of which is a shark fin structure and the tail end of which is a landslide structure. The shark fin structure is higher than the landslide structure, and the shark fin structure and the landslide structure are smoothly connected.
[0011] The shark fin structure, with a height of 8-10mm, is used to split high-speed airflow and reduce turbulence on the roof, while the slope of the ramp structure, with an angle of 10-20°, guides the airflow to a smooth transition.
[0012] Specifically, the trim strip is made of UV-resistant ABS polymer material.
[0013] By adopting the above technical solution, the trim made of UV-resistant ABS material has a good UV protection effect, thus ensuring the long service life of the trim outdoors.
[0014] The beneficial effects of this utility model are as follows: The trim strip, composed of a top plate, a W-shaped water-guiding lower plate, a buckle, and a wind-breaking fin structure, provides a UV-resistant trim strip structure for the water-guiding channels on both sides of the roof of a new energy vehicle. The wind-breaking fin structure improves the wind-breaking effect of the roof during driving, splitting high-speed airflow and reducing turbulence on the roof. The W-shaped water-guiding lower plate, with its two first water-guiding channels at both ends and a second water-guiding channel at the bottom, creates three independent drainage channels between the top plate and the roof's water-guiding channels. These three independent drainage channels reduce the probability of blockage during drainage. Compared to the traditional single drainage channel concentrated in the middle, this application's three drainage channels can effectively reduce blockage even if one or more channels are blocked. Two sets of channels are blocked by dust accumulation, but there are still drainage channels for rainwater to drain away. Because all three drainage channels are open structures, they can be easily cleaned after the trim strip is removed from the roof drainage channel. This solves the problem that the existing trim strip has a single-channel drainage design, which is wide, the water flow is slow, the sand carrying capacity is weak, and it is easy for sand and gravel to accumulate. This application replaces the original single large channel drainage method with three independent channels. When the water flows through any of the channels of this application, its flow rate is higher than that of the large channel, making it easier for sand and gravel to be carried away by the water flow, reducing the possibility of channel blockage. Sand and other debris are easy to accumulate in a single channel, causing drainage failure. This solves the problem that the existing flat cross-section or simple curved design of the trim strip cannot improve the wind resistance of the roof. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figure 1-4 As shown, the UV-resistant polymer trim strip for the roof of a new energy vehicle according to this utility model includes a trim strip 1, which includes a top piece 11, a W-shaped water guide piece 12, a buckle 14, and a wind-breaking fin structure.
[0023] The W-shaped water guide plate 12 is integrally connected to the bottom of the top plate 11, the buckle 14 is integrally connected to both ends of the bottom of the top plate 11, and the wind-breaking fin structure is set on the top of the top plate 11.
[0024] The present invention also includes a first water guide groove 13 formed between the top plate 11 and the W-shaped water guide lower plate 12, and a second water guide groove 15 formed at the bottom center of the W-shaped water guide lower plate 12.
[0025] In use, the W-shaped water guide plate 12, the two sets of first water guide grooves 13 formed at both ends of the W-shaped water guide plate 12, and the second water guide groove 15 formed at the bottom of the W-shaped water guide plate 12, form three independent drainage channels between the top plate 11 and the water guide groove of the car roof. The three independent drainage channels can reduce the probability of blockage during the drainage process. Compared with the traditional setting of a single drainage channel concentrated in the middle, even if one or two of the three drainage channels in this application are blocked by dust accumulation, there are still drainage channels for rainwater to drain. Moreover, since all three drainage channels are open structures, they can be easily cleaned after the trim strip 1 is removed from the drainage groove of the roof, which greatly increases the convenience of later maintenance and use.
[0026] The present invention also includes that the wind-breaking fin structure includes a fin-shaped protrusion 16, the front end of the fin-shaped protrusion 16 is a shark fin structure, the tail end of the fin-shaped protrusion 16 is a landslide structure, and the shark fin structure is higher than the landslide structure, and the shark fin structure and the landslide structure are smoothly connected.
[0027] The shark fin structure, with a height of 8-10mm, is used to split high-speed airflow and reduce turbulence on the roof, while the slope of the ramp structure, with an angle of 10-20°, guides the airflow to a smooth transition.
[0028] This utility model also includes the fact that the decorative strip 1 is made of UV-resistant ABS polymer material.
[0029] When in use, the trim strip 1, made of UV-resistant ABS material, has a good UV protection effect, ensuring the long service life of the entire trim strip outdoors.
[0030] In use, the trim strip 1 is embedded in the drainage grooves on both sides of the car roof, and the buckle 14 is pressed into the buckle of the drainage groove to assemble the entire trim strip 1. During this process, the W-shaped water guide plate 12 is used to form three independent drainage channels between the top plate 11 and the drainage grooves of the car roof. The two sets of first water guide grooves 13 formed at both ends of the W-shaped water guide plate 12 and the second water guide groove 15 formed at the bottom of the W-shaped water guide plate 12. The three independent drainage channels can reduce the probability of blockage during the drainage process. Compared with the traditional setting of a single drainage channel in the middle, even if one or two of the three drainage channels in this application are blocked by dust accumulation, there are still drainage channels for rainwater to drain. Moreover, since all three drainage channels are open structures, they can be easily cleaned after the trim strip 1 is removed from the drainage grooves of the car roof, which greatly increases the convenience of later maintenance and use. The wind-breaking fin structure improves the wind-breaking effect of the car roof during driving, splits the high-speed airflow, reduces turbulence on the roof, and further increases the stability of the car.
[0031] Furthermore, the UV-resistant ABS is model CYCOLAC ABS FR15U.
