Technical Field

[0001] The utility model relates to the technical field of LED vehicle lamps, in particular to a waterproof and sealed LED vehicle lamp structure. Background Art

[0002] Vehicle lamps are an important part of a vehicle, which can provide lighting for the vehicle in case of poor light, foggy weather or at night during driving; among them, LED vehicle lamps refer to that both the external and internal light sources of the vehicle adopt LED technology for external and internal lighting; external lighting devices involve thermal limit and EMC problems, and there are also many complex standards for load unloading tests.

[0003] Currently, most vehicle lamps are composed of a housing and a lamp cover. In order to ensure the sealing performance of the vehicle lamp, waterproof glue is applied at the joint of the housing and the lamp cover. However, during long-term use, the waterproof glue is extremely prone to drying out and then cracking, which affects the subsequent use of the vehicle lamp. Summary of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figures 1-4 , a waterproof and sealed LED headlight structure, including a first housing 1, both sides of the first housing 1 are provided with openings. A lamp cover 2 is installed on one side of the first housing 1, and a first limiting plate 16 is vertically installed on the outer wall of the other side of the first housing 1. A first sealing plate 8 is correspondingly installed on the side of the first limiting plate 16 away from the lamp cover 2, and there is a gap between the first sealing plate 8 and the first housing 1;

[0025] An elastic metal strip 9 is provided on the outer wall of the first sealing plate 8, and a plurality of worm gear grooves 10 arranged at intervals are opened on the metal strip 9. One end of the metal strip 9 is fixed on the first sealing plate 8, and a worm 14 meshing with the worm gear grooves 10 is provided above the other end of the metal strip 9. The end of the worm 14 is coaxially installed with a connecting shaft 13. The connecting shaft 13 is rotatably installed on the fixed seat 12, and the fixed seat 12 is fixed on the support frame 11. The support frame 11 is a "U"-shaped frame with an opening facing the first sealing plate 8, and the bottom of the support frame 11 is fixed on the first sealing plate 8. When the connecting shaft 13 rotates, it can drive the worm 14 to rotate. Due to the meshing of the worm 14 and the worm gear grooves 10, the rotation of the worm 14 can drive one end of the metal strip 9 to move in the support frame 11, so that the metal strip 9 can be tightened or loosened on the first sealing plate 8;

[0026] In order to facilitate the rotation of the worm 14, a screw head 15 is installed at the end of one of the connecting shafts 13. When rotating the worm 14, an operator can take a tool such as a screwdriver and place it on the screw head 15 to rotate the worm 14, facilitating the operation of taking in and releasing the metal strip 9.

[0027] On the side of the first housing 1 away from the lamp housing 2, there is a second housing 3. The outer wall of the second housing 3 is in clearance fit with the inner wall of the first housing 1, and a second limiting plate 17 is vertically installed along the outer wall of the second housing 3. On the side of the second limiting plate 17 close to the first housing 1, a second sealing plate 18 is installed, and the second sealing plate 18 corresponds to the clearance. Among them, both the second sealing plate 18 and the first sealing plate 8 are elastic rubber plates. During use, hold the first housing 1 with the open end facing the second housing 3 and move closer, so that the second sealing plate 18 is inserted between the first sealing plate 8 and the first housing 1. Then, the worm 14 can be rotated, and the tightening of the metal strip 9 squeezes the two sealing plates, causing the sealing plates to deform and closely adhere to each other, thereby reducing the gaps between the sealing plates and between the second sealing plate 18 and the first housing 1, and improving the sealing performance after the connection of the two housings.

[0028] In order to protect the worm 14, an arc-shaped cover plate 22 is provided above the worm 14, and the end of the cover plate 22 is fixed to the fixed seat 12.

[0029] It should be noted that the side of the first limiting plate 16 away from the first housing 1 and the side of the second limiting plate 17 away from the second housing 3 both correspond to the side surface of the metal strip 9, which limits the position of the metal strip 9 on the first sealing plate 8, ensuring that the metal strip 9 can fully act on the sealing plate when tightened, and improving the effect of the metal strip 9 on the sealing plate.

[0030] Specifically, an LED lamp 6 is arranged inside the second housing 3, and an arc-shaped section 7 is arranged along the inner wall of the second housing 3. During actual use, a reflector is installed on the inner wall of the second housing 3 to improve the lighting effect of the LED lamp 6.

[0031] Among them, when the LED lamp 6 needs to be replaced or repaired, the worm 14 can be directly rotated to loosen the metal strip 9 on the sealing plate. At this time, the first housing 1 can be directly pulled off from the second housing 3, facilitating the disassembly and installation between the two housings.

[0032] A chassis 4 is installed on the side of the second housing 3 away from the first housing 1. A controller is arranged inside the chassis 4. The controller is connected to the LED lamp 6 through a wire, and a live wire 21 is connected to the controller. The live wire 21 penetrates through the chassis 4. During actual use, the controller is one of a control main board and a PLC controller to control the LED lamp 6; a plurality of ventilation holes 19 are opened on the side of the chassis 4 away from the second housing 3 to ensure the normal heat dissipation of the controller, and a desiccant box 20 is also installed on the chassis 4. The desiccant box 20 contains desiccant, and the desiccant box 20 corresponds to the ventilation holes 19 to dry the air entering and leaving the chassis 4 to prevent water vapor and the like from entering the chassis 4 and affecting the controller.

[0033] When installing the LED headlight, a plurality of mounting seats 5 arranged at intervals are provided at the edge of the chassis 4. Bolts are penetrated through the mounting seats 5, and the entire LED headlight can be fixed by bolts.

[0034] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
