Abstract
Description
Technical Field
[0001] This disclosure relates to the field of automotive lighting technology, specifically to an automotive lighting system and a vehicle. Background Technology
[0002] When water molecules in the air inside a vehicle's headlights are heated by the light, they turn into water vapor. If airflow is poor and there are dead zones, this vapor will condense into fog or small water droplets on the inside of the headlight lens. Additionally, in high-temperature and high-humidity environments, the air temperature inside the lamp cavity rises with each on-off cycle. When the lights are turned off, this hot air cannot escape quickly, and the humidity inside the lamp cavity increases rapidly due to the influence of the outside air, causing the headlight lens to fog up.
[0003] The conventional solution to headlight fogging is to add vents to the rear housing of the headlight to allow air circulation, and simultaneously apply an anti-fog coating to the inner surface of the headlight lens. This coating causes condensed water molecules to form a uniform water film on the inner surface of the lens, preventing visible fog or water droplets from forming. However, this solution has drawbacks: it is not only costly, but also has a higher chance of water droplets dripping onto the inner surface of the lens, and it can cause cosmetic defects on the inner surface of the lens after prolonged use. Utility Model Content
[0004] The purpose of this disclosure is to provide a vehicle headlight and vehicle that reduces the probability of fogging of the headlight lens.
[0005] To achieve the above objectives, this disclosure provides a vehicle lamp, comprising:

[0008] A defogger box is removably installed at the opening. One end of the defogger box extends into the receiving cavity, and the other end is connected to the rear shell. The defogger box contains a heating element, a heat-conducting plate, and a desiccant arranged sequentially from bottom to top. The heat-conducting plate can evenly transfer the heat from the heating element to the desiccant.
[0009] Optionally, the area of the heat-conducting plate is not less than the area of the desiccant, and the area of the heat-conducting plate is not greater than the area of the heating element.
[0010] Optionally, the defogger box includes:

[0013] Optionally, the connecting cover plate has a port protruding away from the side wall on the side away from the side wall, the heating element is connected to the port, and the port is used to connect to the vehicle controller.
[0014] Optionally, the defogger box further includes:
[0015] Two first slots are respectively disposed on the two side walls, and the opposite side edges of the heating element can be inserted into the two first slots accordingly; and
[0016] Two second slots are respectively disposed on the two side walls and spaced apart from the first slot, and the opposite two side edges of the heat-conducting plate can be inserted into the two second slots respectively.

[0024] Optionally, the vehicle further includes an instrument panel, which has an indicator light connected to the controller. The indicator light is configured to illuminate when the controller is connected to the heating element.
[0025] The above technical solution incorporates a defogger box within the vehicle headlight. This box contains a heating element, a heat-conducting plate, and a desiccant. The desiccant absorbs water vapor inside the headlight, keeping the internal air dry. The placement of the heating element, heat-conducting plate, and desiccant ensures the desiccant is evenly heated by the heating element through the heat-conducting plate, further reducing the possibility of water droplets accumulating on the inner lens of the headlight and causing dripping.

Detailed Implementation
[0037] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0038] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" are defined in relation to the actual orientation of the headlights during use, while directional terms such as "inner" and "outer" are defined in relation to the outline of the corresponding components. The terms "first," "second," etc., are used to distinguish different components and do not imply sequentiality or importance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.
[0039] According to one embodiment of this disclosure, such as Figures 1 to 7 As shown, a vehicle headlight is provided, including a faceplate 11, a rear shell 2, and a defogger box 3. The rear shell 2 can be fastened together with the faceplate 11 to form a receiving cavity, and an opening 21 is provided on the side of the rear shell 2 away from the faceplate 11. The defogger box 3 can be retractably installed at the opening 21, with one end of the defogger box 3 extending into the receiving cavity and the other end connected to the rear shell 2. A heating element 4, a heat-conducting plate 5, and a desiccant 6 are arranged sequentially from bottom to top in the defogger box 3. The heat-conducting plate 5 can evenly transfer the heat of the heating element 4 to the desiccant 6.
[0040] Through the above technical solution, a defogger box 3 is installed in the vehicle headlight. The defogger box 3 contains a heating element 4, a heat-conducting plate 5, and a desiccant 6 stacked inside. The desiccant 6 can absorb water vapor inside the headlight, keeping the air inside the headlight dry. Furthermore, the placement of the heating element 4, heat-conducting plate 5, and desiccant 6 allows the desiccant 6 to be evenly heated by the heating element 4 through the heat-conducting plate 5, further reducing the possibility of water droplets accumulating on the inner cover 11 of the headlight and causing water dripping. In addition, heating the desiccant 6 by the heating element 4 allows for its reuse, reducing maintenance costs for users throughout the entire lifespan of the headlight.
[0041] It should be noted that the desiccant 6 can be a solid block, and 3M adhesive can be applied to the side near the heat-conducting plate 5 to adhere the desiccant 6 to the heat-conducting plate 5. When the desiccant 6 is placed above the heat-conducting plate 5, it can also be in a loose, multi-particle form and spread on the heat-conducting plate 5; this disclosure does not limit this. Regarding the structure of the vehicle headlights, a trim frame 12, a rearview mirror 13, and a daytime running light 14 can be sequentially arranged in the cavity between the faceplate 11 and the rear shell 2. The defogger box 3 can be located between the daytime running light 14 and the rear shell 2. In addition, the vehicle headlights in this disclosure can be headlights, taillights, or turn signals; this disclosure does not limit this.
[0042] Furthermore, the area of the heat-conducting plate 5 is not less than the area of the desiccant 6, and the area of the heat-conducting plate 5 is not greater than the area of the heating element 4. This not only allows the heat-conducting plate 5 to be heated evenly, but also maximizes the contact area between the desiccant 6 and the heat-conducting plate 5, so that the desiccant 6 is heated evenly and the defogging effect is improved.
[0043] According to one embodiment of this disclosure, such as Figures 3 to 6 As shown, the defogger box 3 may include a connecting cover 31 and two opposing sidewalls 32. The connecting cover 31 is detachably connected to the rear shell 2 and located outside the receiving cavity. The connecting cover 31 can be fastened at the opening 21 and abut against the rear shell 2. The two sidewalls 32 are respectively connected to the connecting cover 31, and the heating element 4, the heat-conducting plate 5, and the desiccant 6 are all located between the two sidewalls 32. The connecting cover 31 can be locked at the opening 21 to prevent the defogger box 3 from being completely inserted into the headlight and difficult to remove. At the same time, the connecting cover 31 can seal the opening 21 to reduce the loss of heat when the heating element 4 is heating, and improve the drying effect of the desiccant 6 on the inside of the headlight. Here, the side of the connecting cover 31 away from the sidewall 32 may be provided with a port 311 protruding away from the sidewall 32. The heating element 4 is connected to the port 311, and the port 311 is used to connect to the vehicle controller 7. Thus, the heating element 4 is electrically heated and connected to the vehicle's controller 7 via port 311, allowing the heating element 4 to be repeatedly heated. Furthermore, because port 311 is protruding, it can also act as a handle for easy removal of the defogger box 3. Additionally, port 311 can be equipped with a heating element connection foot 3111 and a humidity detection element connection foot 3112, facilitating easier connection of the heating element 4 housed within the headlights and the humidity detection element 8 (mentioned below) to the controller 7.
[0044] It should be noted that, regarding the arrangement of the heating element 4, the heat-conducting plate 5, and the desiccant 6, the demisting box 3 may also include a bottom wall, which is connected to the side wall 32. The heating element 4, the heat-conducting plate 5, and the desiccant 6 can be stacked on the bottom wall. Additionally, as... Figures 3 to 6As shown, the defogger box 3 may also include two first slots 321 and two second slots 322. The two first slots 321 can be respectively disposed on the two side walls 32, and the opposite side edges of the heating element 4 can be inserted into the two first slots 321. The two second slots 322 can be respectively disposed on the two side walls 32, spaced apart from the first slots 321, and the opposite side edges of the heat-conducting plate 5 can be inserted into the two second slots 322. By reinforcing the heating element 4 and the heat-conducting plate 5 with the first slots 321 and the second slots 322, the possibility of the heating element 4 and the heat-conducting plate 5 detaching from the defogger box can be further reduced.
[0045] According to one embodiment of this disclosure, such as Figures 3 to 5 As shown, the defogger box 3 may also include a first retaining member 33, the two ends of which are detachably connected to the ends of the two side walls 32 away from the connecting cover plate 31. The function of the first retaining member 33 is to reinforce the placement of the heating element 4, the heat-conducting plate 5, and the desiccant 6, preventing them from sliding out of the defogger box 3 from the side away from the connecting cover plate 31. At the same time, the detachable design of the first retaining member 33 also facilitates the replacement of the heating element 4, the heat-conducting plate 5, and the desiccant 6.
[0046] According to one embodiment of this disclosure, such as Figure 1 and Figure 2 As shown, the side of the rear cover 2 away from the face shield 11 can be provided with multiple vent holes 22 at intervals, and vent caps 221 can be provided in the vent holes 22. This is to facilitate the circulation of gas inside the headlight with the outside, so as to reduce the possibility of moisture accumulation inside the headlight.
[0047] Based on the above solution, this disclosure also provides a vehicle, which includes a controller 7, a humidity detection element 8, and the aforementioned headlights. The controller 7 can be connected to the heating element 4 in a switchable manner. The humidity detection element 8 can be connected to the headlights and also connected to the controller 7. Here, the humidity detection element 8 can be a hygrometer or a humidity sensor. The heating element 4 can be connected to the humidity detection element 8 and the controller 7 so that the data obtained by the humidity detection element 8 can determine whether to control the heating element 4 to turn on. Specifically, the humidity detection element 8 can be used to monitor the relative humidity of the gas inside the headlights and feed the monitoring data back to the controller 7 in real time. The humidity detection element 8 can be configured such that when the humidity data detected by the humidity detection element 8 exceeds a threshold, the controller 7 connects to the heating element 4, that is, the controller 7 supplies power to the heating element 4. At this time, the heating element 4 heats the desiccant 6, and the emitted water vapor is discharged through the vents of the rear shell 2 until the relative humidity inside the headlights is lower than the set threshold, at which point the controller 7 stops supplying power.
[0048] It should be noted that since the temperature tolerance parameters of desiccants 6 of different materials are different, in order to ensure the life of desiccant 6, the temperature of heating element 4 can be matched and determined to a set range according to the temperature tolerance parameters of desiccant 6. In order to ensure that the temperature of heating element 4 is within the set range, heating element 4 can also be equipped with a control switch 41. The control switch 41 can be connected in series with heating element 4 and controller 7 to more accurately control and adjust the temperature of heating element 4.
[0049] Furthermore, such as Figure 3 As shown, the defogger box 3 may be provided with a second retainer 34 for placing the humidity detection element 8. The function of the second retainer 34 is to fix the placement position of the humidity detection element 8, so as to reduce the variables caused by the movement of the humidity detection element 8 and improve the stability of the data acquired by the humidity detection element 8. Here, the second retainer 34 can be located on the outside of the defogger box 3 or on the inside of the defogger box 3, and this disclosure does not limit it.
[0050] According to one embodiment of this disclosure, such as Figure 7 As shown, the vehicle may also include an instrument panel, on which an indicator light 9 connected to the controller 7 is provided. The indicator light 9 is configured to illuminate when the controller 7 is connected to the heating element 4, so that the people inside the vehicle can more intuitively confirm whether the heating element 4 is turned on and whether dehumidification is being performed inside the vehicle.
[0051] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
[0052] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0053] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
