Description

Technical Field

[0001] This utility model relates to the field of anti-fogging vehicle lights, specifically an anti-fogging vehicle light. Background Technology

[0002] When the air inside the headlights cools down (e.g., when driving out of an underground parking garage and into a cooler outdoor space), the moisture will condense into water mist. This is almost unavoidable because slight gaps inevitably appear in the headlights during long-term use, causing the air inside the headlights to exchange with the air in the outside space.

[0003] In existing technologies, to avoid condensation and fogging, more efficient defogging technologies generally use a miniature air pump and activated carbon box to extract air from inside the lamp body, filter it, and then send it into the lamp body to prevent moisture condensation. However, this method requires additional air intake and return holes to be opened on the lamp, which results in higher costs. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle light that prevents fogging, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fog-proof vehicle light, comprising a lamp cover, a lamp body installed in the inner cavity of the back end of the lamp cover, a controller installed in the back end of the lamp body, the output end of the controller being connected via a wire to a circuit board mounted on a protruding part of the back end of the lamp body, a lamp hole being formed in the protruding part of the back end of the lamp body, a sealing component being installed on the inner wall of the lamp hole, the front end of the lamp body having a concave structure, a protruding rib integrally formed in the inner cavity of the lamp body, a lamp cavity being formed between adjacent protruding ribs, a connecting pin being installed in the output end of the circuit board that penetrates the lamp hole and extends into the lamp cavity, an LED being installed in the output end of the connecting pin, and the sealing component being tightly fitted onto the outer wall of the connecting pin.

[0006] As a further embodiment of this utility model: the sealing assembly includes a sealing plug that is inserted into the inner wall of the lamp hole, the outer circumference of the sealing plug is integrally formed with a sealing ring that fits tightly against the inner wall of the lamp hole, and the connecting pin is tightly inserted into the inner circumference of the sealing plug.

[0007] As a further embodiment of this utility model: the sealing assembly further includes an upper connecting hole opened in the upper part of the sealing plug and a lower connecting hole opened in the lower part of the sealing plug. The ends of the upper connecting hole and the lower connecting hole away from the lamp cavity extend to the outside of the sealing plug. The output end of the upper connecting hole is connected to a discharge pipe, and the input end of the lower connecting hole is connected to a return pipe.

[0008] As a further embodiment of this utility model: multiple circuit boards are connected in series with the controller via wires, the input terminal of the controller is connected to a connector via wires, and the connector is electrically connected to the vehicle battery via a plug.

[0009] As a further improvement of this utility model: the ends of the upper connecting hole and the lower connecting hole near the lamp cavity are connected to the inner cavity of one end of the lamp cavity.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By setting a sealing mechanism, the design of the sealing mechanism only requires adding a sealing mechanism at the original lamp hole position, without the need to add discharge holes and return holes, and without changing the original injection mold, thus achieving the design of return holes and discharge holes at a lower cost.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5In this embodiment of the present invention, an anti-fogging vehicle light includes a lamp cover 1, a lamp body 3 installed in the inner cavity of the back end of the lamp cover 1, a controller 4 installed in the back end of the lamp body 3, and a circuit board 5 installed on the protruding part of the back end of the controller 4 via a wire. A lamp hole 6 is provided on the protruding part of the back end of the lamp body 3, and a sealing component is installed on the inner wall of the lamp hole 6. The front end of the lamp body 3 has a concave structure, and a protruding rib 8 is integrally formed in the inner cavity of the lamp body 3. The space between adjacent protruding ribs 8 is the lamp cavity. A connecting pin 10 is installed in the output end of the circuit board 5, which penetrates the lamp hole 6 and extends into the lamp cavity. An LED bead 14 is installed in the output end of the connecting pin 10, and the sealing component is tightly fitted into the outer wall of the connecting pin 10.

[0020] In this embodiment: First, when the vehicle is started, the vehicle's battery (not the power battery) begins to discharge. As the battery discharges, the micro air pump, which is electrically connected to the battery, operates. The micro air pump extracts the gas inside the lamp body 3 through the sealing assembly and passes it through the activated carbon box. The activated carbon inside the activated carbon box filters the moisture in the extracted gas. The filtered gas is then transported back into the lamp body 3 through the sealing mechanism, thus preventing the moisture in the air inside the lamp body 3 from condensing when it cools down, which would cause fogging.

[0021] When using the vehicle lights, an electrical signal is sent to the controller 4 by turning on the vehicle lights switch. The controller 4 then controls the circuit board 5 to be powered on. The circuit board 5 provides power to the LED beads 14 through the connection pin 10, thereby realizing the vehicle lights illumination function.

[0022] Please refer to this carefully. Figure 3 , Figure 4 and Figure 5 The sealing assembly includes a sealing plug 7 that is plugged into the inner wall of the lamp hole 6. A sealing ring 13 is integrally formed on the outer circumference of the sealing plug 7 and fits tightly against the inner wall of the lamp hole 6. A connecting pin 10 is tightly plugged into the inner circumference of the sealing plug 7. The sealing assembly also includes an upper connecting hole 11 opened in the upper part of the inside of the sealing plug 7 and a lower connecting hole 12 opened in the lower part of the inside of the sealing plug 7. The ends of the upper connecting hole 11 and the lower connecting hole 12 away from the lamp cavity extend to the outside of the sealing plug 7. The output end of the upper connecting hole 11 is connected to a discharge pipe 15, and the input end of the lower connecting hole 12 is connected to a return pipe 9.

[0023] In this embodiment: the micro air pump is connected to the output end of the discharge pipe 15, the output end of the micro air pump is connected to the activated carbon box, and the output end of the activated carbon box is connected to the return pipe 9 through a pipe. When the vehicle is started, the micro air pump is powered by electricity and generates suction. At this time, the air inside the lamp cavity is sucked out through the upper connection hole 11 under the suction and enters the activated carbon box through the discharge pipe 15. At this time, the moisture contained in the air is intercepted and filtered by the activated carbon in the activated carbon box. Then the air enters the lamp cavity through the return pipe 9, avoiding the problem of condensation and fogging caused by the moisture in the lamp cavity meeting the cold when the vehicle drives out of the underground garage.

[0024] Please refer to this carefully. Figure 1 and Figure 2 Multiple circuit boards 5 are connected in series with the controller 4 via wires. The input terminal of the controller 4 is connected to a connector 2 via wires. The connector 2 is electrically connected to the vehicle battery via a connector.

[0025] In this embodiment: after the plug-in 2 is plugged into the plug connector, it can be electrically connected to the storage battery.

[0026] Please refer to this carefully. Figure 4 and Figure 5 The upper connecting hole 11 and the lower connecting hole 12 are connected to the inner cavity of one end of the lamp cavity at the end of the lamp cavity.

[0027] In this embodiment, this design allows the gas inside the lamp cavity to be discharged outwards, filtered, and then returned to the lamp cavity.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
