[0002] With the development of the times, cars have become an essential means of transportation for people. Among them, headlights are essential parts of cars as warning signs to ensure driving safety in different environments. However, headlights are prone to generate heat during use, causing the air inside the headlights to expand due to heat. In order to ensure the air pressure balance and heat dissipation inside and outside the headlights, a structure for exchanging air with the outside world is set on the headlights so that the headlights can be used in low temperature and high humidity environments. The high-humidity gas in the environment outside the headlights enters the lamp through the air exchange structure. After the headlights stop being used, the temperature difference between the inside and outside of the headlights will cause the moisture inside the headlights to gradually condense into mist, water droplets or ice on the outer mirror, which not only affects the appearance of the headlights, but also affects the use of the headlights.

[0003] In the related art, a commonly used solution is to spray anti-fog paint on the outer mirror of the headlight or add a desiccant inside the headlight.

The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0040] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0041] This embodiment provides a vehicle lamp defogger, which is a part of a vehicle accessory and is arranged in a vehicle lamp assembly, wherein the vehicle lamp assembly is, for example, a front lamp, a side lamp, a rear lamp, and the like.

[0042] A vehicle lamp defogger device, such as Figure 1-Figure 4 As shown, the device comprises a housing 1 and a rear cover 3. The housing 1 is used to place a desiccant 2 to achieve the defogging function of the headlight defogging device and ensure the normal use of the headlight assembly. The housing 1 is connected to the rear cover 3 to fix the desiccant 2 to prevent the desiccant 2 from moving and affecting the drying effect.

[0043] The device housing 1 has a sink cavity 11, and the sink cavity 11 is used to accommodate a desiccant 2. The desiccant 2 is bonded to the sink cavity 11 by double-sided adhesive, for example, to improve the assembly effect of the desiccant 2 and the sink cavity 11. The sink cavity 11 is in a concave groove shape to accommodate the desiccant 2. The wall of the sink cavity 11 is provided with a plurality of through holes 111, and the through holes 111 are used to allow moisture in the headlight assembly to pass through, so that the desiccant 2 absorbs its moisture and avoids the generation of fog in the headlight assembly.

[0044] The device housing 1 is provided with a first mounting surface 12, and a flange body is provided at the opening edge of the sink cavity 11, for example, and the flange body extends along the plane direction of the sink cavity 11. Among them, the side surface of the flange body facing the outside of the sink cavity 11 is the first mounting surface 12, which provides a mounting surface or a blocking surface for the back cover 3 to prevent the back cover 3 from sinking into the sink cavity 11. The flange body can extend along the inner side or the outer side of the sink cavity 11. The inward extension can block part of the sink cavity 11 and form a preliminary shielding for the desiccant 2; the outward extension can ensure the opening size of the sink cavity 11, and the structural form of the desiccant 2 is less restricted. For example, the desiccant 2 can be a soft structure, a hard structure, or an irregular body, and the opening is made as large as possible to ensure that the desiccant 2 can be placed normally in the sink cavity 11.

[0045] An annular reinforcing rib 121 is provided at the edge of the first mounting surface 12, and the annular reinforcing rib 121 can be located at the circumferential outer edge of the first mounting surface 12 to ensure that the first mounting surface 12 has a sufficiently large contact area. The annular reinforcing rib 121 can not only improve the layout strength, but also provide a connection position for the back cover 3. For example, the annular reinforcing rib 121 is provided with a first mounting hole 1211 and a second mounting hole 1212. Drilling holes in the annular reinforcing rib 121 can avoid damaging the integrity and overall strength of the device housing 1.

[0046] The rear cover 3 is detachably connected to the device housing 1 so that the desiccant 2 can be replaced, making the vehicle lamp defogger more flexible and preventing the vehicle lamp defogger from failing. The rear cover 3 has a second mounting surface 33, which provides a mounting surface or contact surface for the device housing 1. The second mounting surface 33 is fitted with the first mounting surface 12 to close the sink cavity 11 and fix the desiccant 2.

[0047] The back cover 3 is provided with a fixing buckle 31 and an elastic buckle 32. The fixing buckle 31 is plugged into the first mounting hole 1211 to initially fix the back cover 3. Under the action of external force, the elastic buckle 32 can be deformed to correspond to the second mounting hole 1212. When the external force is removed, the elastic buckle 32 is plugged into the second mounting hole 1212 to complete the assembly.

[0048] In this embodiment, if Figure 1-Figure 4 As shown, the elastic buckle 32 includes a spring piece 321 and a plug-in block 322, and the spring piece 321 is fixedly connected to the plug-in block 322. The spring piece 321 is fixedly connected to the back cover 3, and the spring piece 321 is along the thickness direction of the back cover 3 (refer to Figure 3 The plug-in block 322 is located on the side wall of the spring piece 321 and extends along the plane direction of the rear cover 3, for example, along the length direction of the rear cover 3 (refer to Figure 3The X-axis shown in the figure) and the orthographic projection of part of the plug-in block 322 does not fall within the rear cover 3, but protrudes from the rear cover 3 to ensure that the plug-in block 322 can be inserted into the second mounting hole 1212.

[0049] When installing the back cover 3 to the device housing 1, the back cover 3 enters the area enclosed by the annular reinforcement rib 121, first insert the fixing buckle 31 into the first mounting hole 1211, press the back cover 3 toward the sink cavity 11, and the wall of the annular reinforcement rib 121 squeezes the plug-in block 322, causing the spring piece 321 to deform and the plug-in block 322 to shift. When the back cover 3 is pressed downward until the first mounting surface 12 and the second mounting surface 33 are in contact, the plug-in block 322 is aligned with the second mounting hole 1212, the spring piece 321 returns to its original state, and the plug-in block 322 is inserted into the second mounting hole 1212. When the back cover 3 needs to be removed, push the plug-in block 322, the spring piece 321 is deformed, the plug-in block 322 withdraws from the second mounting hole 1212, and the back cover 3 is removed.

[0050] The plug block 322 is provided with an inclined surface 3221. When the rear cover 3 is mounted to the device housing 1, the inclined surface 3221 faces the side away from the device housing 1, and the inclined surface 3221 can make the plug block 322 enter the second mounting hole 1212 more smoothly.

[0051] In this embodiment, if Figure 1-Figure 4 As shown, the back cover 3 is provided with a first reinforcing rib 34, which is located on the same side as the elastic buckle 32 and protrudes from the surface of the back cover 3. The first reinforcing rib 34 is provided along the circumference of the elastic buckle 32. The first reinforcing rib 34 is, for example, C-shaped, and the elastic buckle 32 is close to the edge of the back cover 3. The first reinforcing rib 34 half-covers the elastic buckle 32, which can improve the strength of the elastic buckle 32 position, avoid the back cover 3 from being broken by force when the back cover 3 is disassembled, and effectively extend the service life of the back cover 3. At the same time, a branch reinforcing rib 341 can also be provided at the midpoint of the first reinforcing rib 34 to further improve the local strength.

[0052] The first reinforcing rib 34 can prevent the elastic buckle 32 from being deformed excessively and becoming ineffective due to excessive pressure on the elastic buckle 32 on the back cover 3 .

[0053] In this embodiment, if Figure 3 , Figure 4 As shown, the fixing buckle 31 includes a first fixing pin 311 and a second fixing pin 312. The first fixing pin 311 and the second fixing pin 312 are located on the same side of the back cover 3 and are arranged on the side of the back cover 3, protruding from the side wall of the back cover 3, and are conveniently connected to the first mounting hole 1211.

[0054] The first fixing pin 311 and the second fixing pin 312 can be disposed in one first mounting hole 1211 or in different first mounting holes 1211. For example, the first mounting hole 1211 includes a first sub-mounting hole 12111 matched with the first fixing pin 311 and a second sub-mounting hole 12112 matched with the second fixing pin 312, so as to facilitate one-to-one corresponding plugging, improve stability during plugging, and avoid shaking.

[0055] In addition, in order to improve the accuracy of installation and reduce the trial and error rate, the sizes of the first fixing pin 311 and the second fixing pin 312 can be different, so as to facilitate installation error prevention, realize the unique correspondence between the fixing pin and the mounting hole, and improve the installation efficiency. The sizes of the first fixing pin 311 and the second fixing pin 312 can be different, such as different widths and different lengths. It is understandable that the first fixing pin 311 and the second fixing pin 312 can also be different in shape, so as to facilitate distinction, realize rapid assembly, and prevent errors when installing the rear cover 3. The specific situation shall prevail.

[0056] The fixing buckle 31 and the elastic buckle 32 are located on opposite sides for easy insertion and removal. The fixing buckle 31 is provided with an inclined surface, that is, the first fixing pin 311 and the second fixing pin 312 are both provided with inclined surfaces, so as to facilitate smooth installation. Of course, the fixing buckle 31 may not be provided with an inclined surface to ensure that the fixing buckle 31 can be tightly connected to the first mounting hole 1211, which is subject to the actual situation.

[0057] In this embodiment, if Figure 4 As shown, the rear cover 3 is provided with a second reinforcing rib 35 protruding outward, and the second reinforcing rib 35 is arranged vertically and horizontally to improve the overall structural strength of the rear cover 3. The second reinforcing rib 35 is, for example, any one of a cross shape, a field shape, a soil shape, and a scholar shape, wherein the first reinforcing rib 34 and the branch segment reinforcing rib 341 can partially overlap with the second reinforcing rib 35 for easy operation.

[0058] In this embodiment, if Figure 3 As shown, a plurality of third reinforcing ribs 1213 are arranged on the outer side wall of the annular reinforcing rib 121. The third reinforcing ribs 1213 may be triangular or trapezoidal. The third reinforcing ribs 1213 are arranged close to the first mounting hole 1211 and / or the second mounting hole 1212, respectively, so as to improve the structural strength of the side of the annular reinforcing rib 121, thereby solving the problem that the structural strength of the annular reinforcing rib 121 may not be increased due to the opening.

[0059] In this embodiment, if Figure 1-Figure 4As shown, the through hole 111 includes a first hole 1111 and a second hole 1112. The first hole 1111 is arranged on the inner side wall of the sink cavity 11, and the second hole 1112 is arranged on the inner bottom wall of the sink cavity 11. A plurality of first holes 1111 are arranged along the length or width direction of the sink cavity 11 (refer to Figure 3 The first holes 1111 are arranged at intervals along the Y axis shown in the figure. The first holes 1111 are, for example, in the shape of a long strip and extend along the depth direction of the sink cavity 11 to increase the opening area and provide more space for the flow of moisture. A plurality of second holes 1112 are provided and arranged in an array on the inner bottom wall of the sink cavity 11. The second holes 1112 are, for example, in the shape of a circle.

[0060] Among them, the setting of the first hole 1111 and the second hole 1112 ensures that moisture can enter the sinking cavity 11 from multiple directions and positions, thereby achieving full utilization of the desiccant 2. The first hole 1111 and the second hole 1112 can enable the desiccant 2 to quickly contact the moisture in the lamp assembly, ensuring that each position of the desiccant 2 can absorb moisture, ensuring the moisture absorption effect of the desiccant 2, and improving the dryness of the lamp assembly.

[0061] In this embodiment, if Figure 1 , Figure 2 As shown, the vehicle lamp defogger device further includes a seal 4, and the second mounting surface 33 is sealedly connected to the first mounting surface 12 through the seal 4. The seal 4 is, for example, a sealing rubber ring, which is arranged along the circumference of the annular reinforcement rib 121 to ensure that the second mounting surface 33 and the first mounting surface 12 have good sealing performance.

[0062] The sealing member 4 may be bonded to the second mounting surface 33 or the first mounting surface 12 , specifically to the first mounting surface 12 , for example, by means of colloid, for easy installation.

[0063] The headlight defogger device proposed in the present application can adapt to various irregular desiccant structures and has stronger adaptability. When the rear cover is mounted to the device housing, the rear cover is surrounded by the annular reinforcement ribs in the device housing. When water flows down on the device body or the headlight assembly, the annular reinforcement ribs can prevent the water from flowing directly onto the seal between the rear cover and the device body, further reducing the risk of water entering the headlight.

[0064] The present disclosure also proposes a vehicle, including a headlight assembly, wherein the headlight includes a headlight and a headlight housing, and the headlight is arranged in the headlight housing to provide a lighting function for a user and improve the user's driving safety. The headlight assembly is arranged, for example, at the front side, rear side, left side, right side, etc. of the vehicle to meet the vehicle's lighting requirements in different directions.

[0065] The vehicle also includes a headlight defogger as in the above embodiment, which is arranged in the lamp housing to prevent the headlight assembly from generating moisture or fog, thereby affecting the lighting effect. The headlight defogger is, for example, a single body, and is detachably or fixedly arranged in the lamp housing, so as to facilitate replacement of the entire headlight defogger. Alternatively, the headlight defogger is, for example, an integrally formed structure with the lamp housing, which is easy to implement, simplifies the forming process, and saves manpower and time costs.

[0066] The vehicle lamp defogger device in the present application has the advantages of simple structure, convenient installation, firmness, reliability, and reusability, and is conducive to popularization and use.

[0067] The above embodiments are only preferred embodiments for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent substitution or change made by a person skilled in the art based on the present application is within the protection scope of the present application.
