The specific embodiment

Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail.

Present embodiment by front shroud 1, anti-dazzling screen 2, dop 3, bulb 8, lamp holder 10, fore shell 5 and back cover 7, wire frame 14, catch bar 11 and upper and

lower magnet

12 and 16, auxiliary anti-dazzling screen 9, upper and

lower rubber cushion

13 and 15 and water proof ring 4 and waterproof pad 6 constitute.

Front shroud 1 has a tip circle tube for short; Anti-dazzling screen 2 is long half of cylinder, and the position, intermediate portion has lets out unthreaded hole; In the middle of the dop 3 is cavity, has the two-stage step; Anti-dazzling screen 2 upper ends install and fix front shroud 1, and its lower end becomes as a whole with dop 3 assemblies again, is referred to as the dop assembly.

Bulb 8 is encapsulated in above the lamp holder 10, and auxiliary anti-dazzling screen 9 is half of ladder barrel, and its lower end also is installed in above the lamp holder 10, becomes as a whole equally, is referred to as the lamp holder assembly.The latter half arc of auxiliary anti-dazzling screen 9 directly increases to anti-dazzling screen 2 and is close.

Wire frame 14 is the revolving body of " worker " font for the cross section, and its center is a through hole, and the outside coils; The bottom of catch bar 11 is installed on the center of wire frame 14, the upper and lower end of wire frame 14 is adorned upper and

lower rubber cushion

13 and 15 respectively, load onto respectively more thereafter,

lower magnet

12 and 16, upper and

lower magnet

12 and 16 has stipulated an activity space that pumps at wire frame 14 centers work for catch bar 11, and these parts are installed together and have constituted an electromagnetism suction assembly with flexible power output.

Fore shell 5 is big end down, middle empty ladder barrel, and the centre position of the external cylindrical surface of its little cylinder in top has the annular groove that a circle is used to adorn water proof ring 4; Extend one section in the large cylinder of the top downward portion of little cylinder.Back cover 7 is for there being round-ended cylinder, and its feather edge is equipped with the power line inlet device.The tail end that lamp holder assembly and electromagnetism suction assembly utilize the last top of catch bar 11 to buckle into lamp holder 10 links together, pack into then in the fore shell 5, utilize waterproof pad 6 and back cover 7 again, above-mentioned two big assemblies are installed in the inside, and guarantee that the lamp holder assembly can telescopic moving swimmingly in the little cylinder on fore shell 5 tops, so just become the main body of a lamp.The main body of lamp be mounted in the dop assembly in intracardiac, promptly the little cylinder on fore shell 5 tops wears in the endoporus of dop 3, forms whole height lamp.Water proof ring 4, waterproof pad 6 mainly are to be used for the water-tight effect, make aqueous vapor can not intrude into all parts of car light inside and car light inside, have guaranteed service life.

During use, when the coil forward of wire frame 14 outsides is switched on, produce magnetic field, and conduction makes it to become a magnetic catch bar to the catch bar 11 at wire frame 14 centers, its magnetic line of force direction is opposite with the magnetic line of force direction of lower magnet 16, forms same magnetic pole relative position.According to the principle that the same sex of magnetic is repelled each other, catch bar 11 promptly is pulled to the position of magnet 12, and is held securely by the magnetic force in the same way of last magnet 12, and at this moment, coil stops going up power supply, and catch bar 11 is still held by last magnet 12 and keeps former invariant position.Because it is interlock that lamp holder assembly and electromagnetism are inhaled assembly, so bulb 8 will up move synchronously with auxiliary anti-dazzling screen 9, at this moment, the auxiliary anti-dazzling screen 9 of unthreaded hole quilt of letting out in anti-dazzling screen 2 left sides shelters from and seals (in conjunction with Fig. 3 analysis), the light that bulb 8 is sent can only penetrate to the right, left-half is closed, there is not light directive left side---be second position of headlight Lamp cup, the principle that auxiliary in addition anti-dazzling screen 9 adopts the latter half arc directly to increase, make anti-dazzling screen 2 and auxiliary anti-dazzling screen 9 more approaching, thereby the radiation of blocking surplus light more effectively, thereby opposite driver's traffic safety has been guaranteed in the generation of ghost phenomenon when having stopped low lamp effectively.Be low lamp state this moment.
