Description
Technical Field
The invention belongs to the technical field of electrical equipment manufacturing, relates to an optical signal device or a lighting device of an automobile, in particular to a novel demisting structure for an automobile lamp,
background
At present, automobiles enter families with more people, LEDs are adopted in a part of light sources of devices for optical signals or illumination in the field of automobiles, heat generated by the LEDs is less, the phenomenon of fog is more prominent objectively, the optical effect and the appearance of the automobile lamps are influenced, some users can complain about the phenomenon, and the problem that each whole automobile manufacturer and automobile lamp suppliers urgently need to solve is how to reduce and avoid the generation of the fog. The existing solution in the market is to arrange an in-out ventilation structure to quickly dissipate fog; the scheme of adding a drying agent into the breathable film is adopted, so that the generation of fog can be slowed down; and adopt the integrated structure of the ventilated membrane and desiccant, the desiccant can be used repeatedly; in addition, a structure combining moisture absorption and heating and dehumidification is adopted, so that the cost is relatively high. The above schemes can not avoid the generation of fog, the effect is not obvious, and the cost is higher.
Disclosure of Invention
The invention provides a novel demisting structure for a car lamp, aiming at solving the problems. The technical scheme is as follows:
the utility model provides a novel car light defogging structure, includes car light face guard, car light casing, and the car light face guard is integrative with the encapsulation of car light casing, be provided with interior air pressure balancing unit, interior air pressure balancing unit's protection architecture, outer air pressure balancing unit and outer air pressure balancing unit's protection architecture on the car light casing, interior air pressure balancing unit and outer air pressure balancing unit all adopt the flexible tubular construction who has sealed effect, can contract along with the change of atmospheric pressure, change the volume in the lamp and reach atmospheric pressure balance, and the car light structure adopts the totally enclosed encapsulation.
Furthermore, a rubber material area is arranged below the car lamp shell, and the shape of the car lamp shell is changed according to the change of the internal and external pressure of the car lamp shell, so that the function of assisting in adjusting the internal air pressure of the car lamp is achieved.
Furthermore, the rubber material area is prepared into a shell with two components of rubber and plastic in a double-shot injection molding mode.
Furthermore, when the automobile lamp is packaged, a drying agent is placed at the same time, and gas assembled into the automobile lamp is dried and removed at one time.
Furthermore, a drying agent installation groove is formed in the inner side of the car lamp shell and used for placing a drying agent.
Through the design scheme, the invention can bring the following beneficial effects: the novel demisting structure for the car lamp, provided by the invention, completely seals the whole car lamp to prevent water vapor from entering, thoroughly removes damp air mixed in the lamp during the process of assembling the lamp by adding a drying agent, and simultaneously avoids the negative influence caused by air pressure change due to temperature change by arranging the air pressure balancing device. The technical scheme of the invention can thoroughly avoid the generation of fog, improve the optical effect and the appearance beautifying degree of the car lamp, and has the advantages of low cost and easy popularization.
Drawings
The invention will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:
fig. 1 is a schematic structural view of the closed air pressure balancing apparatus of the present invention.
The automobile lamp comprises a lamp shade 1, a lamp shell 2, an inner air pressure balancing device 3, an inner air pressure balancing device 4, an outer air pressure balancing device 5, an outer air pressure balancing device 6 and a rubber material area 7.
Detailed Description
As shown in fig. 1, the present invention is a novel demisting structure for a car lamp, which includes a car lamp cover 1 and a car lamp housing 2, wherein the car lamp cover 1 and the car lamp housing 2 are integrally packaged, an inner air pressure balancing device 4, a protection structure 3 of the inner air pressure balancing device, an outer air pressure balancing device 6 and a protection structure 5 of the outer air pressure balancing device are disposed on the car lamp housing 2, both the inner air pressure balancing device 4 and the outer air pressure balancing device 6 adopt telescopic tube structures with sealing effects, and can contract with the change of air pressure to change the volume in the lamp to achieve air pressure balance, and the car lamp structure adopts totally-enclosed packaging.
Furthermore, a rubber material area 7 is arranged below the car lamp shell 2, and the shape of the car lamp shell is changed according to the change of the internal pressure and the external pressure of the car lamp shell 2, so that the function of assisting in adjusting the air pressure in the car lamp is achieved.
Further, the rubber material area 7 is prepared into a shell with two components of rubber and plastic by adopting a double-shot injection molding mode.
Furthermore, when the automobile lamp is packaged, a drying agent is placed at the same time, and gas assembled into the automobile lamp is dried and removed at one time.
Furthermore, a drying agent installation groove is formed in the inner side of the car lamp shell and used for placing a drying agent.
Humid air in the sealed back car light of joining in marriage of car light passes through the drier and once only gets rid of, when the inside temperature of car light is higher than ambient temperature, inside air inflation, atmospheric pressure increase, the tip through interior atmospheric pressure balancing unit outwards removes and balances atmospheric pressure, the balanced partial atmospheric pressure of rubber material district 7 on supplementary car light casing 2 simultaneously, when the inside temperature of car light is less than ambient temperature, inside air contraction, atmospheric pressure diminishes, the tip through outer atmospheric pressure balancing unit 6 inwards removes and balances atmospheric pressure.
The novel demisting structure for the car lamp, provided by the invention, completely seals the whole car lamp to prevent water vapor from entering, thoroughly removes damp air mixed in the lamp during the process of assembling the lamp by adding a drying agent, and simultaneously avoids the negative influence caused by air pressure change due to temperature change by arranging the air pressure balancing device. The technical scheme of the invention can thoroughly avoid the generation of fog, improve the optical effect and the appearance beautifying degree of the car lamp, and has the advantages of low cost and easy popularization.
This concludes the description of the embodiments of the present invention.
