The method for improving fog widely adopted on the existing automobile headlamp comprises the following steps: the shell is provided with a breathable film or a breathable cap or a drying agent or a mixture of the breathable film or the breathable cap or the drying agent, and the defogging function is realized by reducing the moisture in the air in the lamp shell, but the defect that the fog is difficult to eliminate in a short time still exists, particularly in regions with humid air in the south. For vehicles with long service life, the drying agent can lose effectiveness and can not play a role in defogging. Simultaneously in order to guarantee the aridity of the inside air of lamps and lanterns, so generally adopt the form in fan + radiator + wind channel and then make the steam that car light work produced all at lamp inner loop when dispelling the heat to the car light, but this heat radiation structure still can cause the overheated condition of lamp inner part to the car light that the space is more restricted.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 3, a preferred embodiment of the present invention provides a vehicle lamp with a rapid defogging function, including a lamp housing 1, an exhaust assembly and a breathable film 4, wherein the exhaust assembly is fixedly disposed on the lamp housing 1, and the exhaust assembly is located at a position above the lamp housing 1 after being fixedly mounted on a vehicle, with the vehicle as a reference direction, so that a hot airflow generated by a heating assembly 5 during the operation of the vehicle lamp can automatically rise to the position of the exhaust assembly, thereby conveniently and timely exhausting heat. The ventilation holes 3 are arranged at the bottom and/or on a plurality of groups of outer side walls of the lamp shell 1. The air permeable membrane 4 is completely fixed and covered on the vent hole 3. The arrangement position of the ventilation hole 3 needs to be arranged according to the shape and size of the car lamp and the structure of thermal simulation in the lamp shell 1, and finally the aim to be achieved is to ensure that the air entering from the ventilation hole 3 can pass through the area where the heating component 5 is located in the lamp shell 1 as much as possible, so that the heat can be taken away in time, and the heat dissipation efficiency is improved.

As shown in fig. 3, at least one set of ventilation holes 3 is arranged on the outer side wall farthest from the outer side wall where the air exhaust assembly is arranged. This setting can make the convection current air that forms between ventilation hole 3 and the subassembly of airing exhaust pass through more regions, plays better radiating effect. As shown in fig. 4, the ventilation holes 3 may also be provided as a shaped ventilation area consisting of an arrangement of a plurality of sets of unit sub-holes 31. This is provided to avoid some positions of the lamp envelope 1 where the ventilation holes 3 cannot be opened, and to arrange more positions of the lamp envelope 1 due to the smaller diameter of the unit sub-holes 31. In addition, the axes of the unit sub-holes 31 and the outer wall of the lamp housing 1 are set to different angles, so that different flow directions of the wind entering from the unit sub-holes 31 in the same area can be ensured, the flow direction of the external air entering the lamp housing 1 can be changed more flexibly and more variously, and the targeted unit sub-holes 31 can be arranged according to the heat dissipation requirements of different parts in the lamp housing.

As shown in fig. 3, a mounting chamber 11 is disposed at a mounting position of the exhaust assembly on the lamp housing 1 for mounting and fixing the exhaust assembly. A plurality of groups of side walls close to the position of the exhaust assembly arranged on the lamp shell 1 enclose to form an air gathering structure which gradually shrinks towards the exhaust assembly. The air exhaust assembly is positioned right above the component with the largest heat dissipation capacity in the lamp shell 1. Thereby, a large amount of heat inside the lamp housing 1 can be collected at the air inlet of the suction fan 2. The suction fan 2 is fixedly connected in the arranging chamber 11, and an air suction opening of the suction fan 2 is positioned above the inner side surface of the lamp housing 1. Through the arrangement, hot air can be prevented from being accumulated in a small space enclosed by the side wall of the air inlet of the suction fan 2 and the inner side wall of the lamp shell 1. The air exhaust assembly comprises an air suction fan 2 and a breathable film 4, wherein the breathable film 4 is fixedly arranged on one air exhaust side of the air suction fan 2. The ventilated membrane 4 is an existing membrane and mainly used for filtering moisture in air and ensuring the dryness of the air. Moreover, the suction fan 2 and the breathable film 4 in the invention do not have the problem of long-term failure, and the service life of the suction fan and the breathable film can extend through the life cycle of the whole lamp.

The working principle is as follows:

as shown in fig. 3, according to the principle that hot air flows upwards, hot air generated by each part of the car lamp in the working process can flow to the upper part of the lamp shell 1, at the moment, the suction fan 2 can suck away hot air, the air outlet is formed through the breathable film 4 at the air outlet, meanwhile, pressure difference can be generated inside and outside the lamp shell 1, the air at the external normal temperature can enter the lamp shell 1 through the breathable film 4, the temperature difference inside and outside the lamp is reduced, thereby reducing the generation of fog in the lamp, rapidly eliminating the fog in the lamp, and simultaneously, the heat dissipation in the lamp is also well improved.

The above description is intended to describe in detail the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the claims of the present invention, and all equivalent changes and modifications made within the technical spirit of the present invention should fall within the scope of the claims of the present invention.
