Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobiles, and more specifically, to a vehicle lamp and a vehicle. Background Art
[0002] The problem of automobile fog is a difficult problem in the industry. When fog appears on the surface of the lampshade, it will not only damage the appearance of the entire lamp, but may also cause light pattern deviation due to light refraction, thus affecting the function of the lamp.
[0003] At present, the most notable fogging problem of the whole vehicle is the fogging of transparent lampshade taillights under the sun. Fog is mainly caused by the large temperature difference between the inside and outside of the lampshade, and the condensation of water vapor in the area of the lampshade with lower temperature. Since the transparent lampshade has better light transmittance, under the same solar irradiation conditions, the material inside the transparent lampshade absorbs more solar energy than the red lampshade, resulting in a higher temperature inside the lamp and a larger temperature difference with the outside, making it easier to form fog.
[0004] Traditional methods to solve fogging include adjusting the position of the air holes on the lamp housing, applying anti-fog coating on the lampshade and lamp housing, etc. However, the air holes are set so that water vapor can easily enter the lamp through the air holes when the lamp housing is exposed to rain; and even if the anti-fog coating is applied to the lampshade and lamp housing, there is still a certain probability of fogging.
[0005] Therefore, how to reduce the probability of fogging of vehicle lights has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

DETAILED DESCRIPTION
[0039] The core of the utility model is to disclose a vehicle lamp to reduce the probability of fogging of the vehicle lamp.
[0040] Another core of the utility model is to disclose a vehicle comprising the above-mentioned vehicle lamp.
[0041] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions of the utility model described in the claims. It should be noted that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings. In the absence of conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.
[0042] Combination Figure 1-Figure 4 The vehicle lamp disclosed in the utility model includes a lamp housing 200, a lamp shade 100, a thick-walled member 400, a decorative frame 300 and a light-emitting component; the lamp housing 200 and the lamp shade 100 are connected to form an installation space, and an anti-fog coating is coated on the inner wall of the installation space, that is, an anti-fog coating is coated on the inner wall of the lamp housing 200 and the lamp shade 100. The thick-walled member 400, the decorative frame 300 and the light-emitting component are all arranged in the installation space, and the thick-walled member 400 is arranged on the light-emitting path of the light-emitting component; the thick-walled member 400 and the decorative frame 300 are both made of plastic material, and the outer surface is coated with a water-locking coating 500 for locking water, and the water-locking coating 500 can specifically be varnish or hardened paint. Varnish is a transparent coating that can lock the moisture of the component itself, and hardened paint can also play a role in locking the moisture of the component itself. For example, the hardened paint can be UVHC3000CC hardened paint.
[0043] Plastic parts are hygroscopic and will continuously absorb moisture from the surrounding environment until they are saturated during production, transportation and use. Figure 3 When the car lights are placed in an environment exposed to sunlight, the plastic parts absorb the sun's radiation energy, causing their own temperature to rise rapidly. The moisture in the plastic parts will evaporate into the surrounding environment, increasing the humidity inside the lamp installation space, thereby forming fog in the cold area of the lamp.
[0044] Combination Figure 4 The utility model can prevent the thick-walled parts 400 and the decorative frame 300 from absorbing water during production, transportation and use by coating the outer surfaces of the thick-walled parts 400 and the decorative frame 300 made of plastic in the installation space with a water-locking coating, thereby preventing the internal moisture from emitting into the installation space under sunlight and causing fog condensation, and at the same time will not affect the functions of the thick-walled parts 400 and the decorative frame 300.
[0045] The anti-fog coating has a higher cost than the water-locking coating 500. In addition to its water-locking function, it can also realize the anti-fog of the lampshade 100. Specifically, the anti-fog coating can be an anti-fog paint, and the hydrophilic compound contained in the anti-fog paint can form a hydrophilic layer on the surface of the coating. When water vapor in the air contacts the surface of the coating, due to the hydrophilic effect, the water vapor will quickly and evenly spread to form a thin water film instead of forming fog droplets. In this way, light can pass through the lampshade 100 smoothly, thereby reducing or eliminating the visual effect of fog.
[0046] Compared with the prior art, the present invention sprays a water-locking coating 500 on the decorative frame 300 and the thick-walled part 400 inside the lamp without changing the shape of the entire lamp. This can lock the water vapor inside the plastic parts and prevent them from being released or absorbed, thereby fundamentally reducing the water vapor content in the lamp after sun exposure and greatly reducing the chance of fogging of the lamp.
[0047] The specific structures and matching relationships of the lamp housing 200 , the lampshade 100 , the thick-walled member 400 , the decorative frame 300 and the light output assembly are all prior art and will not be described in detail herein.
[0048] Furthermore, other parts made of plastic materials in the installation space are also coated with a water-locking coating 500 on their outer surfaces. Exemplarily, a bracket assembly for fixing the light-emitting assembly is provided in the installation space, the bracket assembly is made of plastic material, and the outer surface of the bracket assembly is coated with a water-locking coating 500 for locking in water.
[0049] A waterproof coating is applied on the outer walls of the lamp housing 200 and the lampshade 100 to improve the waterproof performance of the vehicle lamp and ensure the light emitting effect of the vehicle lamp. The type of the waterproof coating is not limited.
[0050] In order to further optimize the anti-fog effect, a desiccant can be set in the installation space. The desiccant can directly absorb the water vapor in the installation space.
[0051] Combination Figure 5-Figure 7 In a specific embodiment disclosed in the utility model, a ventilation hole 201 is opened on the lamp housing 200, and a ventilation valve 600 is arranged in the ventilation hole 201. The ventilation valve 600 includes a valve body 610, a waterproof breathable membrane 620 and an adsorption layer 630. The valve body 610 is arranged in the ventilation hole 201 and has a ventilation channel running through it. The ventilation channel connects the installation space and the outside world to ensure the balance of air pressure and temperature inside and outside the installation space. The waterproof breathable membrane 620 is arranged in the breathable channel and has waterproof and breathable functions. When the outside air enters the installation space through the breathable channel, the waterproof breathable membrane 620 only allows gas (including moisture) to pass through and prevents liquids such as rainwater from passing through; the adsorption layer 630 is arranged in the breathable channel. When the outside air enters the installation space through the breathable channel, the adsorption layer 630 can adsorb impurities (including polluted gases and tiny particles, such as sulfur dioxide, nitrogen oxides, dust, etc.) and moisture in the air to ensure that only dry and clean air enters the installation space to avoid damage to the internal components of the lamp.
[0052] The adsorption layer 630 may specifically include an adsorption purification net 632, an adsorbent 631, and other structures having good adsorption performance and capable of adsorbing impurities and moisture in the air (moisture in the air is moisture). For example, the adsorbent 631 may be activated carbon, silica gel, molecular sieve, and the like.
[0053] The utility model achieves a balance of air pressure and temperature inside and outside the installation space through a breathable channel, thereby reducing the temperature in the installation space and reducing the probability of fog generation in the lampshade 100. The adsorption layer 630 and the waterproof breathable membrane 620 are arranged to adsorb impurities and moisture in the polluted gas or moisture flowing through the breathable channel to ensure that the gas entering the installation space through the breathable channel has been free of impurities and moisture, thereby ensuring the dryness and purity of the gas in the installation space and reducing the probability of fog generation.
[0054] In some embodiments, the adsorption layer 630 includes at least one of the adsorption purification net 632 and the adsorbent 631, that is, only the adsorption purification net 632 or the adsorbent 631 is set in the air permeable channel as the adsorption layer 630, or the adsorption purification net 632 and the adsorbent 631 are set as the adsorption layer 630 at the same time, preferably the latter, so as to fully adsorb the impurities and moisture contained in the air in the air permeable channel to ensure the purity and dryness of the gas entering the internal space of the installation space.
[0055] The adsorption purification net 632 and the adsorbent 631 can be flexibly arranged at any position of the air permeable channel. Specifically, the adsorption purification net 632 can be one layer or multiple layers, and the multiple layers of the adsorption purification net 632 can be arranged on the same side or different sides of the waterproof breathable membrane 620, and will not affect the functions of the adsorption purification net 632 and the waterproof breathable membrane 620. The waterproof breathable membrane 620 can be one layer or multiple layers.
[0056] It can be understood that when the adsorption purification net 632 is multi-layered, the ventilation holes on two adjacent layers of the adsorption purification net 632 are staggered along the axial direction of the air permeable channel to achieve maximum adsorption efficiency and enhance the adsorption and filtration effect on impurities and moisture in the air.
[0057] To facilitate the installation of the vent valve 600 on the lamp housing 200, Figure 7 In one embodiment, the air hole 201 is a stepped hole, a positioning protrusion is provided on the valve body 610, and a sealing member (not shown in the figure) is tightly provided between the positioning protrusion and the stepped surface to achieve a sealed connection between the air valve 600 and the lamp housing 200.
[0058] The vehicle disclosed in the utility model includes the above-mentioned headlights, so it also has the above-mentioned structure and beneficial effects. Other structures refer to the prior art and will not be described in detail here.
[0059] The above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the utility model. Various modifications to these embodiments will be obvious to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. The specific technical means in some embodiments can be combined in part or in whole into another embodiment without being explicitly excluded by another embodiment. Therefore, the utility model will not be limited to the embodiments shown in this article, but will conform to the widest range consistent with the principles and novel features disclosed herein.
