[0001] The invention relates to the technical field of LED vehicle lamp modules, and in particular discloses an LED vehicle lamp module with a moisture-proof mechanism. Background Art

[0002] LED modules are integrated LED light boards that combine light groups and constant current drivers. To ensure uniform light and no dizziness, each lamp bead on the LED module light board is usually equipped with a lens. Currently, LED light sources have low heat, uniform reflection and varied shapes, so they are increasingly used in automotive lighting.

[0003] Chinese patent CN212537730U discloses a special LED headlight for underground mines with a moisture-proof device, which includes a lamp body, a protective cover is sleeved on the outside of the lamp body, a connection hole is opened on the bottom wall of the protective cover, the connection hole penetrates the bottom wall of the protective cover, the lamp body is connected to an electric wire, the electric wire is connected to the vehicle through the connection hole, and a drying device is arranged in the side wall of the protective cover. In the present invention, when a vehicle is used underground in a mine, the moisture around the lamp body is absorbed and dried by the drying device in the side wall of the protective cover before entering the lamp body, thereby reducing the probability of moisture entering the lamp body and reducing the damage of the lamp body to the lamp body by moisture, which has the effect of increasing the service life of the headlight.

In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0023] See also Figure 1-5 , an LED car light module with a moisture-proof mechanism, comprising a shell 1, a car light module body 2 is arranged inside the shell 1, a partition 3 is fixedly connected inside the shell 1, a plurality of evenly distributed first ventilation holes 4 are penetrated through the outer wall of the partition 3, a plurality of evenly distributed second ventilation holes 5 are penetrated through the lower end surface of the shell 1, a box body 7 is slidably connected between the lower end surface of the partition 3 and the bottom end surface inside the shell 1, a plurality of evenly distributed third ventilation holes 12 are opened on the bottom end surface of the box body 7, a non-woven bag 16 is placed inside the box body 7, and a desiccant 17 is arranged inside the non-woven bag 16;

[0024] A cavity 8 is provided inside the box body 7, and two symmetrically distributed second limit rings 14 are fixedly connected inside the cavity 8. The interiors of the two second limit rings 14 are slidably connected with a clamping rod 10, and the opposite ends of the two clamping rods 10 extend to the outside of the box body 7. A rotating shaft 9 is rotatably connected inside the cavity 8, and two symmetrically distributed pulling ropes 11 are fixedly connected to the outer wall of the rotating shaft 9, and the other ends of the two pulling ropes 11 are respectively fixedly connected to the two clamping rods 10, and the outer walls of the two clamping rods 10 are fixedly connected with a first limit ring 13, and the outer walls of the two clamping rods 10 are sleeved with a spring 15 located between the first limit ring 13 and the second limit ring 14, and the inner wall of the shell 1 is provided with two clamping grooves 18 matching the clamping rods 10.

[0025] In this embodiment: when replacing the desiccant 17, the rotating shaft 9 is rotated by the knob, and the rotating shaft 9 pulls the two clamping rods 10 to slide relative to each other through the pulling rope 11, so that the two clamping rods 10 are disengaged from the clamping slots 18, so that the box body 7 can be taken out from the shell 1. After replacing the non-woven bag 16 containing the desiccant 17, the box body 7 is inserted into the shell 1. During the process of inserting the box body 7 into the shell 1, the clamping rod 10 slides inwardly under the squeezing action of the inner wall of the shell 1, and then the spring 15 is compressed by the first limiting ring 13. When the clamping rod 10 is aligned with the clamping slot 18, the clamping rod 10 slides outwardly under the elastic force of the spring 15, so as to be clamped into the clamping slot 18 to fix the box body 7. The present invention connects the box body 7 with the desiccant 17 and the shell 1 by clamping, so that the desiccant 17 is convenient to replace.

[0026] As a technical optimization solution of the present invention, a fan 6 is installed on the upper end surface of the partition 3.

[0034] As a technical optimization solution of the present invention, one end of the clamping rod 10 close to the inner wall of the shell 1 is inclined.

[0035] In this embodiment, the end of the clamping rod 10 close to the inner wall of the housing 1 is set as an inclined surface, so that the clamping rod 10 can be easily clamped into the clamping slot 18.

[0036] The working principle and use process of the present invention are as follows: when replacing the desiccant 17, the rotating shaft 9 is rotated by the knob, and the rotating shaft 9 pulls the two clamping rods 10 to slide relative to each other through the pulling rope 11, so that the two clamping rods 10 are disengaged from the clamping slot 18, so that the box body 7 can be taken out from the shell 1. After replacing the non-woven bag 16 containing the desiccant 17, the box body 7 is inserted into the shell 1. During the process of inserting the box body 7 into the shell 1, the clamping rod 10 slides inwardly under the squeezing action of the inner wall of the shell 1, and then the spring 15 is compressed by the first limiting ring 13. When the clamping rod 10 is aligned with the clamping slot 18, the clamping rod 10 slides outwardly under the elastic force of the spring 15, so as to be clamped into the clamping slot 18 to fix the box body 7. The present invention connects the box body 7 with the desiccant 17 and the shell 1 by clamping, so that the desiccant 17 is convenient to replace.
