Abstract
A kind of electronic module hermetic water-proof structure involved in the utility model, including upper cover body and lower case, therebetween it is equipped with the inner cavity that can accommodate electronic module, the contact surface of lower case is equipped with groove, the sealing ring of softer, elastic is equipped in groove, the sealing ring diameter of section is greater than groove section diameter, and the mine dam for being equipped with protrusion is surveyed in the nearly inner cavity of the contact surface of lower case.After upper cover body and lower case engagement flexible deformation occurs for sealing ring, and the contact surface of upper cover body and lower case is closed, prevents outside liquid from penetrating into inner cavity.Mine dam setting, the liquid for failing to be completely cut off by sealing ring can be effectively prevented and flow into inner cavity, furthermore, when flexible deformation occurs for sealing ring, mine dam can also apply resistance thrust to sealing ring, so that elastic deformation mainly occurs outward for sealing ring, so that sealing ring is more bonded with upper cover body with the contact surface of lower case.
Description
Technical field
The utility model relates to a kind of electronic module hermetic water-proof structures, belong to mechanical equipment technical field.
Background technique
With the development of automotive electronics, wherein electronic product using more and more extensive, arrangement environment is also more and more severe
It carves, especially waterproof requirement, for some electronic product modules since position is more severe, waterproof requirement is even as high as IP7 grades
Or 8 grades of waterproofs, it is much straight frequently with dispensing or two shells between two shells of electronic module at present for this high waterproof requirement
It connects welding and reaches sealing, efficiency for dispensing glue is relatively low, and especially glue has solidification too long, causes productive temp slower；What welding needed
Equipment cost is also relatively high, and product loses maintenanceability substantially after welding, needs repairing, is needed to product if product is faulty
Carrying out destructive dismantling just can be carried out, this two kinds of waterproof projects all have some limitations in actual operation.
Utility model content
The purpose of this utility model: being intended to provide a kind of reliable electronic module waterproof construction, and production cost is low, waterproof effect
Fruit is good, install, dismantle, maintenance, then assemble it is all very convenient.
This electronic module waterproof construction, including upper cover body and lower case, electronic module can be accommodated therebetween by being equipped with
Inner cavity, the contact surface of lower case are equipped with groove, the sealing ring of softer, elastic are equipped in groove, and the sealing ring cross-section is straight
Diameter is greater than groove section diameter, and the mine dam for being equipped with protrusion is surveyed in the nearly inner cavity of the contact surface of lower case.
The sealing ring is circle.The sealing ring is rectangular.
The sealing ring material hardness is between 30 degree to 60 degree.
It is using the advantage of technical solutions of the utility model:
1. after upper cover body and lower case engagement flexible deformation occurs for the sealing ring of the present apparatus, by upper cover body and lower case
Contact surface is closed, prevents outside liquid from penetrating into inner cavity.
2. the mine dam of the present apparatus is arranged, the liquid for failing to be completely cut off by sealing ring can be effectively prevented and flow into inner cavity, in addition,
When flexible deformation occurs for sealing ring, mine dam can also apply resistance thrust to sealing ring, so that sealing ring is mainly outward
Elastic deformation occurs, so that sealing ring is more bonded with upper cover body with the contact surface of lower case.
Detailed description of the invention
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, below will be to institute in embodiment
Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only one recorded in the present invention
A little embodiments are also possible to obtain other drawings based on these drawings for those of ordinary skill in the art.
Fig. 1 is the structural schematic diagram of the utility model；
Specific embodiment
We come further detailed to this electronic module hermetic water-proof structure in conjunction with attached drawing and specific example below
Explanation.
This electronic module waterproof construction, including upper cover body and lower case, electronic module can be accommodated therebetween by being equipped with
Inner cavity, the contact surface of lower case are equipped with groove, the sealing ring of softer, elastic are equipped in groove, and the sealing ring cross-section is straight
Diameter is greater than groove section diameter, and the mine dam for being equipped with protrusion is surveyed in the nearly inner cavity of the contact surface of lower case.The sealing ring is circle
Shape.The sealing ring is rectangular.The sealing ring material hardness is between 30 degree to 60 degree.
After lower cover and lower case are combined closely, the sealing ring in lower case groove is under the extruding of upper cover contact level
Elastic deformation occurs, meanwhile, the wall that discharges water of the nearly lumen side of lower casing contact level applies resistance thrust in sealing ring deformation process, prevents
Only deformation occurs to lumen side for sealing ring so that the deformation direction of sealing ring mainly towards outside, can effectively reinforce sealing ring with
Airtightness between upper cover body and lower casing contact level effectively improves the water proof effect of sealing ring.
In addition, by the setting for the wall that discharges water, only a few can be effectively prevented penetrates the liquid of sealing ring and enter inner cavity, into
One step promotes the waterproof performance of this structure.
It is above that certain exemplary embodiments of the utility model are only described by way of explanation, undoubtedly, for
Those skilled in the art can be with a variety of different without departing from the spirit and scope of the utility model
Mode is modified described embodiment.Therefore, above-mentioned attached drawing and description are regarded as illustrative in nature, and should not be construed as
Limitation to the utility model claims protection scope.
