Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The following is for reference. Figures 1-5 Desiccant box 1000 according to a first aspect embodiment of the present invention is described.

[0037] The application of the desiccant box 1000 is not limited. It can be used in vehicles, such as vehicle lights; in household appliances; and in electronic products. This embodiment describes the application of the desiccant box 1000 in vehicle lights as an example, and will not be elaborated further below.

[0038] likeFigure 1 As shown, the desiccant box 1000 according to an embodiment of the present utility model includes: a box body 100.

[0039] The box 100 is used to hold desiccant 200.

[0040] Alternatively, the desiccant 200 may be a desiccant package, desiccant sheet, desiccant rod, or desiccant gel, etc. The specific form of the desiccant 200 can be adjusted, and this application does not impose specific limitations on it.

[0041] Combination Figure 1 The box body 100 includes: a bottom wall structure 10 and a peripheral wall structure 30.

[0042] The peripheral wall structure 30 is cylindrical and one end is connected to the bottom wall structure 10. The bottom wall structure 10 and the peripheral wall structure 30 together form a receiving cavity 101, which is used to contain the desiccant 200. The peripheral wall structure 30 is provided with at least one first vent hole 31.

[0043] The bottom wall structure 10, as part of the box 100, provides a connection platform for the peripheral wall structure 30 and is an important component of the receiving cavity 101.

[0044] Optionally, the bottom wall structure 10 can be a planar structure, but it can also be designed into other shapes to suit specific application scenarios according to actual needs.

[0045] Furthermore, the shape of the bottom wall structure 10 can be adjusted according to actual needs. It can be circular or other regular or irregular shapes to better adapt to the installation space inside the vehicle headlight.

[0046] The peripheral wall structure 30 is a cylindrical structure. Here, "cylindrical" is interpreted broadly, meaning it is not limited to a "circular cylinder" shape; for example, it could be other cylindrical shapes adapted to the bottom wall structure 10. Specifically, the peripheral wall structure 30 can be a shape with closed sides and one end connected to the bottom wall structure 10. Its cross-section can be circular, elliptical, square, rectangular, or other polygonal, or it can be an irregular shape. This design helps the desiccant box 1000 adapt to some complex installation spaces.

[0047] The first vent 31 connects the receiving cavity 101 containing the desiccant 200 to the inside of the headlight, ensuring that the desiccant 200 can efficiently absorb moisture inside the headlight, thereby maintaining a dry environment inside the headlight.

[0048] The first vent 31 is set on the peripheral wall structure 30, which can ensure that moisture enters the desiccant box 1000 evenly from multiple directions, avoid local moisture accumulation, and make full use of the entire surface of the desiccant 200, thereby improving the overall moisture absorption effect.

[0049] Optionally, the first vent 31 is Figures 1-3 The shape shown is rectangular, or the first vent 31 can be designed as a square, or it can be a trapezoid or other polygon, or a circle, or other irregular shapes. The shape of the first vent 31 can be flexibly selected according to actual needs, and this application does not impose specific restrictions.

[0050] The number of first vents 31 can be set flexibly, either one or multiple, depending on the specific application requirements.

[0051] By setting multiple first vents 31, the air circulation channels are increased, making it easier for moisture inside the headlight to enter the receiving cavity 101, thereby improving the dryness of the headlight's internal environment.

[0052] Furthermore, combined Figure 2 and Figure 3 When there are multiple first vent holes 31, the multiple first vent holes 31 are arranged at intervals along the circumferential direction of the peripheral wall structure 30, which can ensure that moisture can enter the desiccant box 1000 evenly and improve the moisture absorption efficiency.

[0053] Alternatively, when there are multiple first vents 31, their arrangement can be flexibly configured according to the specific internal structure of the headlight. For example, multiple first vents 31 can be provided in areas with higher humidity to increase airflow in those areas, ensuring that moisture can quickly enter the receiving cavity 101 and be absorbed by the desiccant 200. Similarly, multiple first vents 31 can also be provided near the connection point to improve local moisture absorption efficiency and provide optimal protection.

[0054] To improve the stability of the desiccant box 1000 during use, such as Figure 1 As shown, the desiccant box 100's box body 100 is mounted on the headlight housing 2000.

[0055] Furthermore, in order to improve the connection stability and sealing between the housing 100 and the headlight structure, such as Figures 1-3 As shown, the box body 100 also includes a sealing snap edge 40.

[0056] Optionally, the sealing edge 40 is provided on the edge of the bottom wall structure 10 or on the outer peripheral surface of the peripheral wall structure 30.

[0057] Specifically, when the box 100 is installed on the vehicle light, the sealing edge 40 can fit tightly against the installation position, thereby fixing the box 100 to the vehicle light. At the same time, it helps to reduce the amount of moisture entering the vehicle light from the gap between the desiccant box 1000 and the vehicle light housing 2000, ensuring that the desiccant 200 can work efficiently in a closed environment, improving moisture absorption efficiency, keeping the internal structure of the vehicle light dry, and extending the service life of the vehicle light.

[0058] The sealing edge 40 is a ring shape. This ensures that when the desiccant box 100 is installed on the vehicle headlight, it can achieve a tight fit in multiple directions, further improving the reliability and efficiency of the desiccant box 1000.

[0059] In some alternative embodiments, combined with Figure 3 The sealing edge 40 extends along the edge of the bottom wall structure 10. This arrangement ensures that the housing 100 fits snugly against the mounting surface of the headlight housing 2000 when installed, while minimizing occupancy of other areas.

[0060] Optionally, the sealing edge 40 is provided on the outer peripheral surface of the peripheral wall structure 30. This arrangement allows the housing 100 to fit tightly against the inner side wall of the vehicle lamp through the sealing edge 40 on the peripheral wall when it is installed into the vehicle lamp housing 2000, forming an effective lateral seal and preventing moisture from entering from the side.

[0061] like Figures 1-3 As shown, the housing 100 also includes a locking protrusion 50. The locking protrusion 50 is provided on the peripheral wall structure 30, and the locking protrusion 50 and the sealing edge 40 are spaced apart along the axial direction of the housing 100, forming a mounting groove 102 for engaging the vehicle lamp housing 2000.

[0062] Specifically, when the desiccant box 1000 is installed on the vehicle light assembly, the vehicle light housing 2000 is located in the mounting groove 102 between the locking protrusion 50 and the sealing edge 40. This arrangement ensures a tight fit between the desiccant box 1000 and the vehicle light housing 2000 while avoiding interference with other components.

[0063] The locking protrusion 50 extends circumferentially along the peripheral wall structure 30 to provide a more uniform and secure fixation. This effectively prevents the desiccant box 1000 from loosening or shifting during use, ensuring its long-term stable operation.

[0064] By extending circumferentially along the peripheral wall structure 30, the contact area between the locking protrusion 50 and the headlight housing 2000 is increased, further enhancing the overall sealing performance. This also helps prevent moisture from entering the desiccant box 1000, thereby improving the moisture-proof effect.

[0065] Furthermore, the locking protrusion 50 makes the installation process simpler and faster. Simply insert the desiccant box 1000 into the headlight housing 2000, and the mounting groove 102 formed by the locking protrusion 50 and the sealing edge 40 allows for quick and reliable installation without the need for additional fixing devices. Therefore, in this embodiment, the desiccant box, by providing the sealing edge 40 and the locking protrusion 50 to form a reliable mounting groove 102, achieves a stable connection between the desiccant box 1000 and the headlight housing 2000, and facilitates quick and easy installation and removal of the desiccant box 1000.

[0066] Alternatively, the locking protrusion 50 can be designed in segments to provide multi-directional fixation and support, depending on actual needs.

[0067] like Figure 4 As shown, there are four locking protrusions 50, which are evenly distributed circumferentially. This ensures that the desiccant box 1000 is subjected to balanced force during installation, and each locking protrusion 50 provides a stable support point. Especially when the vehicle encounters vibration and impact during driving, the four evenly distributed locking protrusions 50 can effectively prevent the desiccant box 1000 from tilting or loosening.

[0068] At the same time, this symmetrical design reduces the directional requirements during installation and simplifies the operation.

[0069] Optionally, the size or position of the locking protrusion 50 can be adjusted according to actual needs to adapt to different installation environments. For example, in certain special scenarios, the setting position of the locking protrusion 50 can be changed.

[0070] In some alternative embodiments, the locking protrusion 50 has a chamfer on the side facing the sealing edge 40. This facilitates smooth rotation of the desiccant box 1000 into the headlight housing 2000, improving installation ease.

[0071] like Figure 3 As shown, the first vent 31 is located on the side of the locking protrusion 50 away from the mounting groove 102.

[0072] With this configuration, when the desiccant box 1000 is installed on the headlight housing 2000, all the first vents 31 are located inside the headlight, ensuring that the moisture inside the headlight can be absorbed efficiently, further ensuring the moisture absorption effect.

[0073] like Figure 2 As shown, the desiccant box 1000 according to some optional embodiments of the present invention also includes a sealing ring 60, which is mounted on the outer peripheral wall structure 30 and located in the mounting groove 102.

[0074] The sealing ring 60 further enhances the seal between the desiccant box 1000 and the headlight housing 2000, preventing moisture from seeping in through gaps. By placing the sealing ring 60 within the mounting groove 102, not only is increased friction prevented from shifting the desiccant box 1000 after installation, but a uniform and reliable seal is also provided. This design ensures the desiccant box 1000 remains stable during vehicle operation, effectively improving overall moisture protection.

[0075] In some alternative embodiments, an opening 301 is formed at the end of the peripheral wall structure 30 that is away from the bottom wall structure 10.

[0076] The opening 301 is directly connected to the receiving cavity 101. Its main function is to provide users with a convenient operating channel for placing or removing the desiccant 200.

[0077] The opening 301 is located at the end of the peripheral wall structure 30 away from the bottom wall structure 10, which ensures the space utilization of the receiving cavity 101 and does not affect the installation and cooperation of the desiccant box 1000 with other components, thus ensuring the compactness and functionality of the overall structure.

[0078] like Figures 1-2 As shown, the desiccant box 1000 also includes a cover 70 for blocking the opening 301, the cover 70 being detachably connected to the peripheral wall structure 30.

[0079] The cover 70 is positioned at the opening 301 to prevent the desiccant 200 from falling out and to ensure that the desiccant 200 remains in the predetermined position during use and will not be scattered or displaced due to vibration or other external forces.

[0080] The cover 70 and the peripheral wall structure 30 are detachably connected, which facilitates the disassembly and assembly of the cover 70, making it easier to replace the desiccant 200. This avoids performance degradation caused by the desiccant 200 becoming saturated with moisture, ensuring the dryness inside the headlight and thus extending the overall service life of the headlight's internal components.

[0081] The detachable connection between the cover 70 and the peripheral wall structure 30 can be a snap-fit ​​connection, a magnetic connection, or a sliding lock connection, etc.

[0082] Further, optionally, combined Figure 2 and Figure 3The cover 70 has at least two latching protrusions 71 along its circumferential edge. The peripheral wall structure 30 has latching grooves 32 corresponding to the latching protrusions 71. Each latching groove 32 includes an entry section 321 and a fixing section 322. The entry section 321 is open on the side facing the opening 301. The fixing section 322 extends circumferentially along the cover 70, and one section of the fixing section 322 is connected to the entry section 321. Each fixing section 322 is located in a first direction of the entry section 321 in the circumferential direction. Each latching protrusion 71 enters through the entry section 321 and then screws into the fixing section 322 in the first direction.

[0083] In the above technical solution, these protrusions 71 are evenly distributed to ensure balanced force distribution. Simultaneously, corresponding slots 32 are provided on the peripheral wall structure 30, with each slot 32 corresponding to one protrusion 71. Each slot 32 includes an entry section 321 and a fixing section 322. The entry section 321 is open on the side facing the opening 301, facilitating easy entry of the protrusion 71. The fixing section 322 extends circumferentially along the cover 70, with one section connected to the entry section 321, forming a complete closed path.

[0084] During installation, first align the cover 70 with the opening 301 on the peripheral wall structure 30, so that the latching protrusion 71 aligns with the entry section 321 of the slot 32. Since the entry section 321 is open on one side, the latching protrusion 71 can easily slide in. After the latching protrusion 71 is fully inserted into the entry section 321, rotate the cover 70 in the first direction so that the latching protrusion 71 is screwed from the entry section 321 into the fixing section 322. The fixing section 322 ensures that the latching protrusion 71 can be firmly locked in place after rotation, preventing the cover 70 from accidentally loosening or falling off.

[0085] Conversely, during the process of removing the cover 70, the cover 70 is rotated in the opposite direction of the first direction, so that the latch 71 moves from the fixed section 322 to the entry section 321. Then, the cover 70 is gently lifted in the vertical direction of the first direction to separate it from the peripheral wall structure 30, so that the cover 70 is completely removed from the slot 32.

[0086] Through the cooperation of the latch 71 and the slot 32, the cover 70 can be quickly installed and removed without additional tools, greatly improving the replacement of the desiccant 200. At the same time, the fixed section 322 ensures that the cover 70 remains stable when encountering vibrations and impacts during vehicle operation.

[0087] Alternatively, the surface of the fixed section 322 that contacts the protrusion 71 has an anti-slip layer.

[0088] The anti-slip layer helps enhance the stability of the 71. Optionally, the anti-slip layer can be a rubber layer, a silicone layer, etc. An anti-slip adhesive layer can also be applied to achieve the anti-slip effect.

[0089] In further optional embodiments, such asFigure 1 and Figure 2 As shown, the cover 70 has at least one second vent 72.

[0090] The second vent 72 provides an additional airflow channel for the desiccant box 1000.

[0091] When the second vent 72 works in conjunction with the first vent 31 on the peripheral wall structure 30, the moisture inside the headlight can enter the receiving cavity 101 through two paths, achieving more uniform airflow and ensuring full contact with the desiccant 200 from multiple directions, thus improving moisture absorption efficiency. This multi-directional ventilation arrangement ensures full utilization of the surface of the desiccant 200.

[0092] Optionally, there are multiple second vents 72, and these multiple second vents 72 are centrally symmetrically distributed with respect to the center of the cover 70. The centrally symmetrical distribution of multiple second vents 72 ensures more uniform airflow within the space below the cover 70. This layout helps improve overall ventilation efficiency and reduces the possibility of insufficient or excessive ventilation in localized areas.

[0093] Optionally, the second vent 72 can be circular, or it can be designed as a square, or it can be a trapezoid, rectangle, or other polygonal shape, or other irregular shape. The shape of the second vent 72 can be flexibly selected according to actual needs, and this application does not impose specific limitations.

[0094] Optionally, please refer to Figure 1 and Figure 2 The cover 70 also includes at least one radially extending first reinforcing rib 73, and the first reinforcing rib 73 and the second vent hole 72 are alternately arranged on the cover 70 in the circumferential direction.

[0095] The first reinforcing rib 73 improves the overall mechanical properties of the cover 70 by dispersing stress, enhancing its structural strength and stability, and reducing the probability of deformation of the cover 70.

[0096] The first reinforcing rib 73 and the second vent 72 are arranged alternately to ensure unobstructed ventilation and good moisture absorption effect.

[0097] Combination Figure 2 Multiple first reinforcing ribs 73 are arranged to extend circumferentially along the cover body 70. This arrangement can enhance the structural stability of the cover body 70 from multiple directions, allowing stress to be more evenly distributed across the entire cover body 70, effectively improving its resistance to deformation.

[0098] According to some optional embodiments of the present invention, the box body 100 further includes a second reinforcing rib 80, which is disposed on at least one side of the bottom wall structure 10.

[0099] The second reinforcing rib 80 is located on one or more sides of the bottom wall structure 10, which can effectively disperse the pressure or impact force on the bottom wall. The presence of the second reinforcing rib 80 not only enhances the rigidity of the bottom wall structure 10, but also indirectly improves the stability of the entire desiccant box 1000.

[0100] like Figure 4 As shown, the second reinforcing rib 80 is located on the side of the bottom wall structure 10 facing the receiving cavity 101.

[0101] like Figure 5 As shown, the second reinforcing rib 80 is located on the side of the bottom wall structure 10 away from the receiving cavity 101.

[0102] like Figures 6-7 As shown, the vehicle lighting device according to a second aspect embodiment of the present invention includes: a housing 2000 and a desiccant box 1000. The housing 2000 has a mounting hole 2001 communicating with the interior. The peripheral wall structure 30 of the box body 100 in the desiccant box 1000 is inserted into the mounting hole 2001. The edge of the mounting hole 2001 has a mounting opening 2002. After the locking protrusion 50 is inserted into the housing 2000 through the mounting opening 2002, it is rotated to cause the edge of the mounting hole 2001 to engage in the mounting groove 102.

[0103] Combination Figure 6 There are four mounting ports 2002, and each mounting port 2002 corresponds to the locking protrusion 50 of the desiccant box 1000.

[0104] After the desiccant box 1000 is fixed to the housing 2000, the first vent 31 of its peripheral wall structure 30 and the second vent 72 of the cover 70 are both located inside the vehicle lamp device. This arrangement allows air from inside the vehicle lamp to enter the desiccant box 1000 through multiple ventilation holes, enabling the desiccant 200 to exert its dehumidifying effect and effectively prevent fogging and condensation inside the vehicle lamp. This not only keeps the internal environment of the vehicle lamp device dry but also improves the stability and lifespan of the vehicle lamp.

[0105] In some alternative embodiments, combined with Figure 6 and Figure 7 The housing 2000 is also provided with a limiting member 2003 at the edge of the mounting hole 2001, and the limiting member 2003 is spaced apart from the mounting opening 2002. The locking protrusion 50 enters the mounting opening 2002 and rotates to abut against the limiting member 2003.

[0106] Here, the limiting member 2003 provides precise positioning for locking the desiccant box 1000. Specifically, after the desiccant box 1000 is inserted into the mounting hole 2001, the locking protrusion 50 on it first enters the mounting opening 2002, and then, through a rotational operation, moves the locking protrusion 50 to a position contacting the limiting member 2003. The presence of the limiting member 2003 effectively indicates the correct installation position of the desiccant box 1000, helping to ensure that the desiccant box 1000 is accurately positioned in the mounting hole 2001 and preventing improper installation due to misoperation.

[0107] Alternatively, there may be multiple limiting members 2003, and the multiple limiting members 2003 are arranged at intervals. The multiple limiting members 2003 are evenly distributed on the edge of the mounting opening 2002, which can disperse the externally applied forces (such as stress generated by insertion, rotation or vibration) and avoid deformation or damage caused by local stress concentration.

[0108] Furthermore, the edge of the mounting port 2002 may be a relatively weak part of the housing 2000 structure. Therefore, setting multiple limiting members 2003 can provide additional support for this area and improve its resistance to deformation.

[0109] Because the edges of the mounting port 2002 are reinforced, the entire housing 2000 can better maintain its shape and function during long-term use, reducing the risk of wear or failure and extending the service life of the vehicle lighting device.

[0110] The vehicle according to the third aspect of the present invention includes the vehicle lighting device according to the second aspect of the present invention.

[0111] It is worth noting that the specific type of vehicle referred to in this application is not limited; for example, the vehicle can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. The vehicle using the improved headlight device according to this utility model embodiment can maintain stable dryness of the headlight device and extend its service life. This, in turn, improves vehicle reliability and reduces maintenance frequency and costs.
