The lamp shell and the face mask are sealed by a closed-loop rubber groove structure, so that the size of the lamp is larger than the sizes of the two rubber grooves, and the space required by the two rubber grooves is at least the shell wall thickness 4+ the mask rubber leg wall thickness 2+ the rubber thickness 4. Especially on slender type lamps and lanterns, if adopt the sealed scheme of traditional gluey groove, the required space is big, so the part size is big, and is with high costs, and lamps and lanterns molding is restricted, and to present the technical current situation that whether space or molding demand all increases day by day, obviously can appear the not enough problem in space.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem of the prior art, the embodiment of the utility model provides a seal structure for car lamps and lanterns has reduced the required space size of lamps and lanterns seal structure for lamps and lanterns overall dimension reduces greatly, has not only satisfied the sealed space demand of increasing miniaturization of present lamps and lanterns and can use the diversified molding demand that molding element increases, still has that lamps and lanterns seal structure functional, manufacturing process are simple and advantage with little costs.

The utility model provides a seal structure for car lamps and lanterns, seal structure includes that face guard glues groove, casing glue leg and sealed glue, the casing glue leg with two cell walls in face guard glue groove constitute the sealed glue groove that the section structure is the mountain type, sealed glue fill in sealed glue inslot.

Preferably, the cross-sectional structure of the mask glue groove is a V-shaped structure.

Preferably, the free ends of the shell rubber legs face to the direction away from the groove bottom of the mask rubber groove.

Preferably, the shell body is located in the mask glue groove and close to the groove bottom position of the mask glue groove.

The embodiment of the utility model provides a seal structure for car lamps and lanterns compares prior art, has following beneficial effect:

1. compared with the traditional rubber groove sealing structure, the required space size of the sealing structure is reduced, accordingly, the overall size of the lamp can be greatly reduced, and meanwhile, the cost is reduced;

2. under the condition that the whole size of the lamp meets certain requirements, the reduction of the occupied space of the sealing structure enables the modeling space of the lamp to be more loose, and therefore the requirement for increasing modeling elements is met to a certain extent.

3. In addition, the sealing structure of the herringbone rubber groove can completely meet the functional requirements on the sealing performance, has certain performance stability, and is not easy to crack after being impacted by machinery and vibration;

4. in addition, in the manufacturing process, the production can be realized by adopting the traditional gluing process equipment, the process is simple, the equipment does not need to be newly added or replaced, and the cost is saved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following description will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the term "connected" is to be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; may be a mechanical connection, may be a conductive connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The embodiment of the utility model provides a seal structure for automobile lamp, through glue groove seal structure basis at the tradition, two upper and lower (perhaps control) gluey grooves of the gluey groove of closed loop type unite two into one to carry out configuration optimization, the required space size of lamps and lanterns seal structure has been reduced, make lamps and lanterns overall dimension reduce greatly, not only satisfied present lamps and lanterns sealed space demand that increases miniaturization and can use the diversified molding demand that molding element increases, still have lamps and lanterns seal structure functional, manufacturing process is simple and advantage with low costs.
