Later there is the lamp factory to paste the drier inside the lamps and lanterns, but the drier reaches life or absorbs water the state and reach after the saturation, can't absorb the inside steam of lamps and lanterns and can't change, and final still hazy, this kind of mode has certain ageing, addresses the symptoms and does not cure the basis.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a lid structure behind removable drier to solve the problem that proposes among the above-mentioned background art.

The utility model provides a lid structure behind removable drier, including back lid, sealing washer and lamp body, lid is whole cylindricly behind the drier, middle fretwork, then place the drier in the back lid, a plurality of bleeder vents are arranged to the back lid side wall, set up a tegillum on the back lid 1, tegillum and back lid are through a piece muscle structural connection, tegillum opposite side has a ring formula buckle, back lid base embolias the sealing washer, sealing washer and lamp body interference fit, back lid both sides respectively have a cantilever type buckle, 2 cantilever type buckle symmetric distributions, 2 the cantilever type buckle is pressed to be packed into in the lamp body and is hugged closely fixedly with lamp body card foot.

The small cover and the rear cover are integrally formed in an injection molding mode.

The utility model discloses a back lid both sides respectively have a cantilever type buckle, can directly press the lamp body of packing into through buckle structure, and easy operation is convenient, and lid cantilever type buckle is hugged closely fixedly behind the card foot on the lamp body and the drier, reaches fine sealed effect, prevents inside outside steam gets into lamps and lanterns, reduces drier life, avoids frequently changing the drier. When the drying agent rear cover is replaced, the lamp shell can be separated only by pinching 2 cantilever type buckles at the same time, and the drying agent rear cover is easily detached.

Detailed Description

In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, the utility model is further explained by combining the specific implementation mode.

As shown in fig. 1, 2, 3, 4, and 5, the desiccant-replaceable rear cover structure includes a rear cover 1, a sealing ring 2, and a lamp housing 4, wherein the rear cover 1 is cylindrical and hollow in the middle. The drying agent 3 is placed in the drying agent rear cover 1, and a plurality of air holes 105 are distributed on the side wall of the drying agent rear cover 1, so that the drying agent can absorb water vapor in the lamp conveniently; in order to prevent the drying agent from falling off, a small cover 101 is designed on the rear cover 1, the small cover 101 and the rear cover 1 are connected through a thin rib structure 102, therefore, a part can be developed in the design, a circular ring type buckle 103 is arranged on the other side of the small cover 101, and the small cover 101 and the rear cover 1 are integrally injection-molded, so that the cost is reduced. After the drying agent 3 is loaded into the rear cover 1, the small cover 101 is hung into the rear cover 1 through the rotary ring type buckle 103, and the operation is simple and time-saving. The sealing ring 2 is sleeved in the base of the rear cover 1, the sealing ring 2 is in interference fit with the lamp shell 4, two small-wing-shaped cantilever type buckles 104 are respectively arranged on two sides of the rear cover 1, 2 cantilever type buckles 104 are symmetrically distributed at an included angle of 180 degrees, the 2 cantilever type buckles 104 can be simultaneously pressed by one hand, and the cantilever type buckles 104 are directly pressed into the lamp shell 4 to be tightly attached and fixed with the lamp shell clamping feet 401. In the state of the whole vehicle, if the drying agent 3 needs to be replaced, the whole rear cover assembly needs to be detached and then the drying agent 3 needs to be replaced, and the replacement space of the rear part of the lamp is smaller under the general condition. The advantage of the replaceable desiccant rear cover structure is also embodied, the connection between the cantilever type buckle 104 and the main body on the two sides of the rear cover 1 is locally reduced, so that the activity range of the cantilever type buckle 104 is increased, only one hand is needed to press the two symmetrical cantilever type buckles 104 lightly, through the lever principle, the two cantilever type buckles 104 are separated from the lamp housing clamping feet 401 in a rotating mode around the sheet rib structure 102, the rear cover 1 can be separated from the lamp housing 4 easily, the replacement can be carried out without other tools, and the operation is easy, simple and convenient.

As shown in fig. 5, 6 and 7, the structure of the replaceable desiccant rear cover has an advantage that most of the mask subassemblies 5 and the lamp housings 4 are glued and pressed automatically by a machine at present, when the mask subassemblies 5 are provided with modules, the module connectors 501 of the mask subassemblies and the wiring harness connectors 402 of the lamp housings need to be taken out through the lamp housing holes 4 after the mask subassemblies 5 and the lamp housings 4 are pressed, the two are inserted and then put into the lamp housings 4, and finally the desiccant rear cover is installed.

The utility model discloses a improve on the basis of lid behind the lamps and lanterns wiring, cover the direct cylindric structure that increases after and be used for fixed drier, remain original face guard sub-assembly promptly and pencil after the lamp body pressfitting to the function of inserting, also can change the drier, reach a thing dual-purpose.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
