Description

A kind of waterproof sealing structure of vehicle xenon headlight fixer shell

Technical field

The utility model relates to a kind of automobile lamp, especially relates to a kind of and the waterproof sealing structure matching used auxiliary equipment of this automobile lamp, belongs to the automobile lamp field.

Background technology

Headlight for vehicles is one of main light fixture in the automobile lamp, and its effect is to illuminate the road of vehicle front and scenery on every side, makes the driver safety driving.

At present the Halogen lamp LED that generally uses of headlight for vehicles is replaced by xenon headlight gradually, and xenon headlight has more advantage: long service life is 10 times of Halogen lamp LED; Luminosity is strong, is 3 times of Halogen lamp LED, and the light of radiation is a kind of brilliant ultrawhite light that bores; Power consumption is few, reduces 50% than Halogen lamp LED, and the performance of xenon headlight meets the requirement of headlight for vehicles luminous intensity distribution performance.But it is bright that xenon headlight requires have very high voltage to swash, it swashs bright voltage and is about 23000V, must supporting use a kind of name is called the auxiliary equipment of " stabilizer ", the effect of stabilizer is 12V low-voltage on the automobile to be boosted to about 23000V high voltage supply with xenon headlight, after swashing bright xenon headlight, dropped to the operate as normal of keeping xenon headlight about 80V in 1 minute.

Stabilizer is by electronic devices and components, circuit board and shell constitute, electronic devices and components in the shell and circuit board can not make moist and water drenches, moistureproof requirement is very strict, at present, the electronic devices and components of stabilizer and circuit board generally are to be placed in an aluminium outer casing container or the metal material outer casing container, its sealing means is rubber filling type sealing or the sealing of marine glue cushion, rubber filling type sealing is that electronic devices and components and the circuit board with stabilizer is placed in the shell, in outer casing container, fill and fill a kind of soft electronic casting glue or rigid electron pouring sealant, be wrapped in the electronic devices and components and the circuit board of stabilizer in the casting glue fully, its advantage is that sealing property moistureproof and waterproof performance is good, shortcoming is that casting glue will be filled full entire container, and the waste raw material increase cost and complex process, and can not keep in repair and renewal part, need integral replacing; Marine glue cushion sealing is to install one deck waterproof pad in the cover plate of outer casing container additional, its advantage be simple and easy for installation, cost is low, its shortcoming is that waterproof and dampproof poor-performing is unreliable, is a kind of orthoscopic hermetically-sealed construction.More than two kinds of water-tight modes all have shortcoming and defect.

Summary of the invention

The purpose of this utility model provides a kind of waterproof sealing structure of vehicle xenon headlight fixer shell, and it is good that the sealing structure has waterproof and dampproof performance, simple in structure, easy to manufacture, the easy for installation and low remarkable advantage of cost.

The principle of technical solutions of the utility model is dioptric type sealing principle and structure.

As everyone knows, the dioptric type hermetically-sealed construction improves greatly than the sealing property of orthoscopic hermetically-sealed construction, significant sealing affection, and sealing property is superior.

Concrete technical scheme of the present utility model is, front shroud that the shell of stabilizer is stamped to form by the aluminum shell framework and the sheet metal of rectangle and back shroud cover and constitute, and the electronic devices and components of stabilizer and circuit board are placed in the inside of shell.The periphery that casing frame and forward and backward cover plate cover is step-like chimb, during sealing and the groove of cover plate form the dioptric type sealing.The inner face periphery that closes behind forward and backward cover plate and the casing frame lid strikes out groove, the shape of groove is consistent with the stairstepping chimb of casing frame periphery, size is a bit larger tham the ladder chimb, when forward and backward cover plate and casing frame cover, the stairstepping chimb of casing frame just embeds in the groove of forward and backward cover plate, makes casing frame and forward and backward cover plate become the shell of a sealing.

During encapsulation, at first the electronic devices and components and the circuit board of stabilizer are put in the casing frame, viscosity waterproof construction glue with a kind of industrial thickness is poured in the groove of forward and backward cover plate then, and former and later two covers with forward and backward cover plate and casing frame close again, finishes whole assembling.

Industry viscosity waterproof construction glue is the waterproof flexible glue that can solidify under a kind of normal temperature, have extremely strong viscosity and waterproof action, can be with casing frame and forward and backward cover plate good bond, viscose glue stairstepping chimb along casing frame in the groove of forward and backward cover plate forms dioptric type sealing shape, makes the waterproof sealing impact of performance remarkable.After tested, even the stabilizer of this kind hermetically-sealed construction is immersed in the water, can not seep water and make moist yet.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Front shroud 3 that the shell of stabilizer is stamped to form by the aluminum shell framework 2 and the sheet metal of rectangle and back shroud 6 cover and constitute, and the electronic devices and components of stabilizer and circuit board are placed in the inside of shell.Casing frame 2 has step-like chimb 11 with the periphery that front shroud 3 covers, and the periphery of front shroud inner face strikes out front shroud groove 4; Outside framework 2 has step-like chimb 9 with the periphery that back shroud 6 covers, the periphery of back shroud inner face strikes out back shroud groove 7, the shape of front shroud groove 4 and back shroud groove 7 is consistent with the

stairstepping chimb

11 and 9 of casing frame 2 peripheries, size is a bit larger tham the stairstepping chimb, just embed in the groove of forward and backward cover plate, become the shell of an involution.

During encapsulation, before a kind of industrial viscosity waterproof construction glue 10 and 8 is poured in respectively, in the back shroud groove 4 and 7, then front shroud 3 and back shroud 6 are covered with casing frame 2 respectively, the

stairstepping chimb

11 and 9 of casing frame 2 embeds respectively in the viscosity waterproof construction glue 10 and 8 in front and rear cover plate groove and the groove, after the adhesive curing of viscosity waterproof construction casing frame 2 is become monolithic case with front shroud 3 with back shroud 6 cementations, viscosity waterproof construction glue fill full casing frame stairstepping chimb with before, space between the back shroud groove, form the dioptric type hermetically-sealed construction, make the waterproof and dampproof impact of performance of stabilizer shell remarkable.

The effect of xenon headlight circuit line cover 1 is that stabilizer output 23000V high-tension electricity passes through for the circuit line of xenon headlight.

The effect of power input line cover 5 is that the power input line of stabilizer input 12V low tension passes through.

Screw hole 12 is to reinforce forward and backward cover plate to be connected effect with casing frame.
