[0004] One of the LED car lights with good sealing performance in the above-mentioned comparative documents is to install a lampshade outside the diffuser plate to achieve good sealing and protection of the lighting area to avoid the generation of water mist. In actual operation, the vehicle will generate large vibrations during operation. This vibration may cause gaps in the connection of the headlights, thereby affecting the sealing performance inside the headlights. In addition, the lamps inside the headlights are connected to the external structure of the headlights, which may have an adverse effect on the sealing inside the headlights at the connection. Utility Model Content

[0005] The utility model aims to provide a highly sealed automobile rear lamp to solve the problem in the above-mentioned background technology that a large vibration will be generated during the operation of the vehicle, and this vibration may cause gaps in the connection of the lamp, thereby affecting the sealing performance inside the lamp.

[0006] To achieve the above object, the utility model provides the following technical solutions: a highly sealed automobile rear lamp, comprising a fixing frame, a protective net, and a lampshade, wherein the protective net is fixedly connected to one side of the fixing frame, and the protective net is set as a frame structure, and the lampshade is fixedly connected to the inner side of the protective net;

[0007] A sealing structure for sealing the inside of the lamp is provided on the inner side of the fixed frame, and the sealing structure includes a connecting ring fixedly connected to the inner side of the fixed frame, and a sealing ring is fixedly connected to the inner side of the connecting ring. A groove is provided between the fixed frame, the connecting ring and the sealing ring, and an elastic sealing strip is fixedly connected inside the groove.

[0008] Preferably, a plurality of equally spaced connecting sleeves are provided on the side of the sealing ring, and the connecting sleeves penetrate the interior of the sealing ring, and threads are provided inside the connecting sleeves.

[0009] Preferably, a sealing plate is attached to one side of the sealing ring, and a plurality of sliding holes distributed at equal distances are provided on the side of the sealing plate, and the sliding holes are aligned with the connecting sleeve.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The high-sealability automobile rear lamp is provided with a sealing structure. When the lamp is vibrated and the connecting screws become loose, the limiting effect of the connecting screws is weakened, which may cause a certain gap between the sealing ring and the sealing plate. However, since the elastic sealing strip is compressed between the sealing plate and the connecting ring, when a gap appears between the sealing ring and the sealing plate, the elastic sealing strip fills the gap with its elasticity, thereby maintaining the sealing inside the lamp.

[0016] Furthermore, a sealed space is constructed between the protective net, the sealing plate, the mounting ring, and the sealing cover, and the LED lamp bead is connected to the inside of the sealing cover by means of threads, so that the light-emitting part thereof is located inside the sealing cover. When the LED lamp bead is installed and fixed, the LED lamp bead and the sealed space between the protective net, the sealing plate, the mounting ring, and the sealing cover do not interfere with each other. With the design of the transparent material of the sealing cover, when the LED lamp bead is working, the light emitted can pass through the sealing cover and the lampshade, thereby illuminating the external environment.

[0017] Furthermore, the protective net is arranged outside the lampshade, so that when the headlight is hit by an external object, the protective net can provide a certain degree of protection to the lampshade, thereby enabling the headlight to adapt to a relatively harsh environment.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In a further preferred embodiment of the present invention, Figure 1 - Figure 6As shown, a high-sealability automobile rear lamp comprises a fixing frame 1, a protective net 2, and a lampshade 3. The protective net 2 is fixedly connected to one side of the fixing frame 1, and the protective net 2 is set as a frame structure, and the lampshade 3 is fixedly connected to the inner side of the protective net 2; a sealing structure for sealing the inside of the lamp is provided on the inner side of the fixing frame 1, and the sealing structure comprises a connecting ring 4 fixedly connected to the inner side of the fixing frame 1, and a sealing ring 6 is fixedly connected to the inner side of the connecting ring 4, a groove is provided between the fixing frame 1, the connecting ring 4, and the sealing ring 6, and an elastic sealing strip 5 is fixedly connected inside the groove, a plurality of equidistantly distributed connecting sleeves 7 are provided on the side of the sealing ring 6, and the connecting sleeve 7 passes through the inside of the sealing ring 6, and a thread is provided inside the connecting sleeve 7, a sealing plate 8 is attached to one side of the sealing ring 6, and a plurality of equidistantly distributed sliding holes 9 are provided on the side of the sealing plate 8, The sliding hole 9 is aligned with the connecting sleeve 7, and the connecting sleeve 7 is internally threadedly connected with a connecting screw 10, and the connecting screw 10 passes through the sliding hole 9, and the end of the connecting screw 10 fits with the side of the sealing plate 8, and the end of the connecting sleeve 7 is slidably connected to the inside of the sliding hole 9, and the sealing plate 8 is provided with three openings that are equidistantly distributed inside, and each opening is fixedly connected with a mounting ring 11, and a sealing cover 12 is fixedly connected to one side of the mounting ring 11, and the sealing cover 12 is located inside the protective net 2, and the mounting ring 11 is provided with threads inside, and the sealing cover 12 is set to a transparent material, and a sealed space is formed between the protective net 2, the sealing plate 8, the mounting ring 11, and the sealing cover 12, and the mounting ring 11 is internally threadedly connected with an LED lamp bead 13, and the light-emitting part of the LED lamp bead 13 is located inside the sealing cover 12;

[0027] First, the connecting screw 10 is passed through the inside of the vehicle body, so that it is fixed to the vehicle body through the connecting sleeve 7, so as to achieve mutual connection between the headlight and the vehicle body. When the connecting screw 10 is installed inside the connecting sleeve 7, the connecting screw 10 will slide inside the sliding hole 9, thereby driving the sealing plate 8 to move toward the sealing ring 6, so that the connecting sleeve 7 is installed inside the sliding hole 9. At this time, the sealing plate 8 will contact the elastic sealing strip 5, so that it and the connecting ring 4 can compress the elastic sealing strip 5 together until the sealing plate 8 and the sealing ring 6 are tightly fitted. At this time, a sealing structure is formed between the sealing plate 8 and the sealing ring 6;

[0028] When the lamp is vibrated and the connecting screw 10 is loosened, the restrictive effect of the connecting screw 10 is weakened, which may cause a certain gap between the sealing ring 6 and the sealing plate 8. However, since the elastic sealing strip 5 is compressed between the sealing plate 8 and the connecting ring 4, when a gap appears between the sealing ring 6 and the sealing plate 8, the elastic sealing strip 5 fills the gap with its elasticity, thereby maintaining the sealing inside the lamp.

[0029] A sealed space is constructed between the protective net 2, the sealing plate 8, the mounting ring 11, and the sealing cover 12, and the LED lamp bead 13 is connected to the inside of the sealing cover 12 by means of threads, so that the light-emitting part thereof is located inside the sealing cover 12. When the LED lamp bead 13 is installed and fixed, the sealed space between the LED lamp bead 13 and the protective net 2, the sealing plate 8, the mounting ring 11, and the sealing cover 12 does not interfere with each other. With the design of the transparent material of the sealing cover 12, when the LED lamp bead 13 is working, the light emitted can pass through the sealing cover 12 and the lampshade 3, thereby illuminating the external environment;

[0030] The protection net 2 is arranged outside the lampshade 3, so that when the headlight is hit by external objects, the protection net 2 can provide a certain degree of protection to the lampshade 3, thereby enabling the headlight to adapt to a relatively harsh environment.
