[0002] With the development of science and technology, vehicles have become widely used in people's daily lives. Taillights, as an important component of vehicles, can serve as a warning and alert to vehicles behind. However, in cold and snowy weather, water droplets and fog easily form on the inner surface of the lampshades of existing vehicle taillights, affecting the lighting effect of the vehicle's taillights.

[0003] Therefore, it is necessary to provide a new taillight structure and vehicle to solve the above technical problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a taillight structure and a vehicle, aiming to solve the technical problem that the existing vehicle taillights have poor lighting effects in low-temperature snowy weather.

[0032] As an important part of the vehicle, the taillight can play a role in warning and alerting the vehicles behind. Figure 1 The upper surface of the taillight's lampshade 100' is often exposed to the outside environment, and some even have recessed structures. In cold, snowy weather, a large amount of snow can accumulate on the taillight's lampshade 100', accelerating the condensation rate of water vapor inside the taillight, affecting the vehicle's taillight's lighting performance. The specific mechanism is this: in cold environments, the temperature of water vapor inside the taillight is higher, while the taillight's lampshade 100' is lower due to contact with the outside air and accumulated snow. During use, the water vapor inside the lampshade 100' releases heat and condenses upon contact with the cooler lampshade 100', gathering inside the lampshade 100' to form water droplets. Furthermore, as the water droplets accumulate inside the taillight, they converge and flow down the inner wall of the lampshade 100'. Over time, the condensed water droplets inside the lampshade 100' will flow along the inner surface 130 of the lampshade 100', forming traces and affecting the taillight's lighting performance.

[0033] The utility model provides a taillight structure and a vehicle, aiming to solve the technical problem that the existing vehicle taillights have poor lighting effects in low-temperature snowy weather.

[0034] See also Figure 2 and Figure 3 In one embodiment of the present invention, the taillight structure includes a lampshade 100 and a body sheet metal 200. The lampshade 100 has an outer side surface, and the outer side surface includes a horizontal area 110 and an inclined area 120 connected in sequence; the body sheet metal 200 is arranged above the horizontal area 110; when snow falls to the inclined area 120, the snow can automatically slide down along the inclined area 120.

[0035] The technical solution of the present invention is to design an inclined area 120 on the outer side of the lampshade 100 so that snow falling into the inclined area 120 can slide freely. The vehicle body sheet metal 200 is arranged above the horizontal area 110 to block the horizontal area 110, thereby preventing the formation of snow accumulation, reducing the condensation rate of water vapor, and further reducing the rate of water droplet formation, thereby ensuring the lighting effect of the vehicle's taillights. In this embodiment, the lampshade 100 is arranged at the installation location of the taillight to protect the vehicle's taillights. The outer side of the lampshade 100 includes the horizontal area 110 and the inclined area 120. The inclined area 120 allows snow to automatically slide off when it falls into the inclined area 120, thereby preventing snow accumulation in the inclined area 120. The vehicle body sheet metal 200 is arranged above the horizontal area 110 to provide a shielding effect, preventing snow accumulation in the horizontal area 110. Specifically, when the vehicle is in a low-temperature snowy environment, the body sheet metal 200 arranged above the horizontal area 110 can prevent snow from falling to the horizontal area 110, thereby avoiding the formation of snow accumulation. Snow falling to the inclined area 120 will automatically slide down under the action of gravity, thereby avoiding the formation of snow accumulation on the lampshade 100, reducing the condensation rate of water vapor, reducing the generation rate of water droplets, and ensuring the lighting effect of the vehicle's taillights.

[0036] See also Figure 3In one embodiment of the present invention, the horizontal region 110 includes a horizontal surface 111, and the inclined region 120 includes a first inclined surface 121 and a second inclined surface 122. The horizontal surface 111, the first inclined surface 121, and the second inclined surface 122 are sequentially connected. The inclination angle of the first inclined surface 121 is smaller than the inclination angle of the second inclined surface 122. When snow falls onto the first inclined surface 121 and the second inclined surface 122, the snow can slide off automatically. The inclination angle refers to the angle between the inclined surface and the horizontal surface 111. In this embodiment, a first inclined surface 121 and a second inclined surface 122 connected in sequence are used to form an inclined area 120, which can meet the stamping limit of the body sheet metal 200; specifically, if a single inclined surface is used as the inclined area, in order to ensure that the lampshade 100 can completely accommodate the taillight, the area of ​​the horizontal area 110 needs to be increased. Accordingly, in order to ensure that the body sheet metal 200 can completely block the horizontal area 110, the size of the body sheet metal 200 also needs to be increased, but this often exceeds the impact limit of the body sheet metal 200. Therefore, in order to meet the stamping limit of the body sheet metal 200, the taillight structure uses a first inclined surface 121 and a second inclined surface 122 connected in sequence to form an inclined area 120, which reduces the area of ​​the horizontal area 110, and then reduces the size of the body sheet metal 200 to meet the stamping limit of the body sheet metal 200. Furthermore, the outer surface of the lampshade 100 is composed of a horizontal surface 111, a first inclined surface 121, and a second inclined surface 122, each with increasing inclination angles. This optimizes the outer contour and shape of the lampshade 100, making it more aesthetically pleasing, and thus enhancing the appearance of the vehicle. Furthermore, it reduces sharp edges of the lampshade 100 to ensure safety.

[0037] In one embodiment of the present invention, the lampshade 100 has a suitable tilt angle. The tilt angle of the first inclined surface 121 is greater than the suitable tilt angle, and the suitable tilt angle satisfies the requirement that snow automatically slides off when it falls onto the inclined area 120. Specifically, the suitable tilt angle satisfies the requirement that snow automatically slides off when it falls onto the lampshade 100, i.e., when snow falls onto the inclined surface, it automatically slides off under the action of gravity. Therefore, the tilt angle of the first inclined surface 121 is greater than the suitable tilt angle, so that snow automatically slides off when it falls onto the first inclined surface 121. Accordingly, the tilt angle of the second inclined surface 122 is greater than the tilt angle of the first inclined surface 121. Therefore, the tilt angle of the second inclined surface 122 should also be greater than the suitable tilt angle, so that snow automatically slides off when it falls onto the second inclined surface 122.

[0038] In a specific embodiment of the present invention, the suitable inclination angle is equal to 50°.

[0039] See also Figure 2In one embodiment of the present invention, the vehicle body sheet metal 200 is disposed directly above the horizontal region 110. Specifically, the vehicle body sheet metal 200 is disposed directly above the horizontal region 110, that is, directly above the horizontal plane 111. This allows the vehicle body sheet metal 200 to block the horizontal plane 111, preventing snow from falling onto the horizontal plane 111 and thus preventing snow from accumulating on the lampshade 100.

[0040] In one embodiment of the present invention, the vehicle body sheet metal 200 has a corner 210, and the junction between the horizontal region 110 and the inclined region 120 is disposed corresponding to the corner 210. Specifically, the corner 210 of the vehicle body sheet metal 200 is disposed corresponding to the junction between the horizontal region 110 and the inclined region 120. This allows the vehicle body sheet metal 200 to better shield the horizontal region 110, preventing snow from falling on the horizontal region 110 and thus preventing snow from accumulating on the lampshade 100.

[0041] See also Figure 2 In one embodiment of the present invention, the lampshade 100 further comprises an inner side surface 130, which is provided with an anti-fog coating 131. Specifically, the provision of the anti-fog coating 131 can reduce condensation of water vapor on the inner side surface 130 of the lampshade 100, thereby maintaining the clarity and transparency of the lampshade 100. In one specific embodiment, the anti-fog coating 131 is a hydrophilic component. That is, the anti-fog coating 131 has hydrophilic properties, which can increase the tension of liquid water adhering thereto, ultimately causing the liquid water to form a water film on the inner wall of the lampshade 100. This water film neither affects the lighting effect of the vehicle's taillights nor prevents dust from adhering to the inner side surface 130 of the lampshade 100. By adopting the hydrophilic anti-fog coating 131, liquid water can form a water film on the inner wall of the lampshade 100, that is, it can prevent water droplets formed by condensation from flowing down along the inner side surface 130 of the lampshade 100. In this way, the formation of traces on the inner side surface 130 of the lampshade 100 can be avoided, thereby ensuring the lighting effect of the vehicle's taillights.

[0042] In one embodiment of the present invention, both the horizontal region 110 and the inclined region 120 are provided with decorative stripes. Specifically, by providing decorative stripes on the horizontal region 110 and the inclined region 120, i.e., on the outer surface of the lampshade 100, the lampshade 100 is enhanced in appearance, thereby enhancing the appearance of the vehicle. In one specific embodiment, to ensure that light emitted by the vehicle's taillights can pass through the lampshade 100, the lampshade 100 is made of a light-transmitting material such as acrylic.

[0043] In order to prevent snow from accumulating on the inclined area 120 of the lampshade 100, the inclined angle of the inclined area 120 of the lampshade 100 needs to be sufficiently large. Specifically, the weight of the snow attached to the lampshade 100 along the inclined area 120 of the lampshade 100 is greater than the friction between the lampshade 100 and the snow, and the friction between the lampshade 100 and the snow is equal to the product of the weight of the snow along the direction perpendicular to the lampshade 100 and the friction coefficient between the snow and the lampshade 100. However, the existing lampshade 100 has a variety of decorative stripes, and different decorative stripes correspond to different friction coefficients. In addition, since the shape of snow is uncertain and ice is formed due to temperature changes, it is difficult to measure the friction coefficient between the snow and the lampshade 100. Therefore, the present invention, by setting an appropriate inclination angle to design the structure of the lampshade 100, can avoid measuring the friction coefficient between the snow and the lampshade 100, thereby reducing the design difficulty.

[0044] The present invention provides a measuring method for measuring the suitable tilt angle mentioned above, which comprises:

[0045] S100, before designing the structure of the lampshade 100, prepare a flat lampshade 100, wherein the lampshade 100 has specific decorative stripes;

[0046] S200, placing the lampshade 100 horizontally, and placing a certain mass (such as 5g, 10g, 15g, 20g, etc.) of snow without ice on the lampshade 100;

[0047] S300, placing the lampshade 100 in an environment at 0° and gradually tilting the lampshade 100;

[0048] S400, when the snow starts to slide, recording the tilt angle of the lampshade 100 to obtain a reference tilt angle of the lampshade 100;

[0049] S500 , repeating steps S200 to S400 to obtain a reference tilt angle of the lampshade 100 when snow of different masses is placed, and then averaging multiple reference tilt angles to obtain a suitable tilt angle.

[0050] When designing a lampshade 100 with different decorative stripes, the above steps can be repeated to measure the appropriate inclination angles corresponding to the various decorative stripes. When designing the lampshade 100, it is only necessary to make the inclination angle of the first inclined surface 121 greater than the corresponding appropriate inclination angle to avoid snow accumulation.

[0051] The present utility model also proposes a vehicle, which includes a taillight structure. The specific structure of the taillight structure refers to the above-mentioned embodiment. Since this vehicle adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
