Description
Technical Field
The present invention relates to an automotive ventilation cap, and more particularly, to an automotive ventilation cap having a simple structure, capable of being easily assembled, having waterproof and shockproof functions, and having ventilation properties.
Background
Generally, a breathable cap is used for a housing of an automotive electrical component, such as a headlamp, a tail lamp, a fog lamp, a turn signal lamp, a motor, various pressure sensors, a pressure switch, and a housing of an electronic control device.
That is, in the case of the electric component, a ventilation cap is provided at an opening portion formed to communicate between the inside and the outside of the case to prevent water, dust, and the like from flowing into the inside thereof, to alleviate a pressure change in the case due to a temperature change, to transmit sound between the inside and the outside of the case, and to discharge gas and moisture generated in the case.
Conventionally, a housing of an electric component for an automobile exposed to pollutants such as rainwater, muddy water, oil, and the like generally has a tubular opening, and a breathable cap having an L-shaped cylindrical body is used for the opening. The above-mentioned ventilation cap prevents the direct attachment of pollutants to the mounting opening. Finally, the mounting opening is not blocked, and the air permeability and the water resistance of the mounting opening are guaranteed. However, perfect air permeability and water resistance cannot be secured according to the change of the external environment.
In the prior art, in the case where more shock resistance or water resistance is required, the filter member may be attached to the open end of the housing before the cylindrical body is combined with the opening.
However, even if the cylindrical bodies are joined, it is not possible to prevent water, dust, and the like from flowing into the interior of the housing of the automotive electrical component or the like. In order to clearly correct the inflow of water, dust, etc. into the interior of the housing, in the case of increasing the length of the cylindrical body, the space required to install the cylindrical body and the manufacturing cost of the cylindrical body will increase.
Also, a labyrinth may be provided inside the cylindrical body, thereby filtering out foreign substances, in which case the structure of the cylindrical body will become complicated, and thus, the cost will be increased.
Further, in order to perform functions such as waterproofing and anti-vibration, the conventional breathable caps have been tried in various ways in addition to the above-described various ways, and finally, components for performing the functions or additional structures are added, so that the overall size increases and the manufacturing cost increases.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily carry out the present invention. The present invention can be embodied in a variety of different forms, and is not limited to the embodiments described in the present specification. In order to clearly explain the present invention in the drawings, portions that are not related to the description are omitted, and the same reference numerals are given to the same or similar components throughout the specification.
In the present specification, it is to be understood that the terms "comprises" or "comprising," or the like, are used to specify the presence of stated features, integers, steps, acts, elements, components, or groups thereof, and do not preclude the presence or addition of one or more other features, integers, steps, acts, elements, components, or groups thereof. In addition, when a part of a layer, a film, a region, a plate, or the like is "on" another part, the part includes not only a part directly on the other part but also a part having another part in the middle thereof. Conversely, the case where a portion of a film, a region, a plate, or the like is "under" other portions includes not only the case where the portion is directly under the other portions but also the case where the other portions are present therebetween.
Hereinafter, the automotive ventilation cap 1 according to an embodiment of the present invention will be described in more detail with reference to the drawings.
The automotive ventilation cap 1 according to the first embodiment of the present invention is applied to an automotive ventilation cap that is attached to a cylindrical opening 101, and the cylindrical opening 101 is provided to protrude from the outer shell of an automotive part 100.
The automotive ventilation cap 1 of the present invention includes a body 10 and a cover member 30.
Referring to fig. 2 to 4, the body 10 is formed in a cylindrical shape, is fixed by being closely inserted into an outer surface of the opening 101, has an enlarged diameter portion 12 on an outer surface thereof, and is ventilated by providing a plurality of vent holes 13 in the enlarged diameter portion 12 along a longitudinal direction thereof. In this case, the outer surface of the enlarged diameter portion 12 may be provided with wrinkles. The closure is maintained by the formation of wrinkles and prevents post-assembly detachment.
The body 10 is substantially cylindrical and is formed of two portions having different outer diameters, that is, a reduced diameter portion 11 and an enlarged diameter portion 12. The diameter-enlarged portion 12 may be a portion whose outer diameter increases from the diameter-reduced portion 11. Therefore, the inner diameter of the body 10 is the same, but the outer diameter is divided into two parts.
Referring to fig. 3, a cut portion 10a is formed at a distal end of the body 10 so that the opening 101 of the member 100 can be easily inserted.
The enlarged diameter portion 12 of the main body 10 is an enlarged diameter portion, and the vent hole 13 is formed in the enlarged diameter portion 12 in a radial shape. When air is supplied to the inside and outside of the main body 10, the ventilation hole 13 can adjust the amount of ventilation.
That is, the ventilation amount can be adjusted by adjusting the diameter of the ventilation holes 13 or adjusting the number of the ventilation holes 13.
Referring to fig. 3, the cover member 30 is formed in a cylindrical shape having a closed end and is closely inserted into an outer surface of the body 10, and the closed end is provided with a step 31 for limiting the insertion of the body 10 when the body 10 is inserted so that the vent hole 13 has a space 30a communicating with a hollow portion of the body 10.
The lid member 30 is formed in a lid shape having a closed end, and particularly, it is important to form the step 31 on the side surface. If the step 31 is not provided, the main body 10 is inserted into the inner end of the cover member 30, thereby blocking the air passage.
The step 31 is formed at a position not to block the vent hole 13.
Therefore, the air passage between the opening 101 and the outside is formed by the space formed by the vent hole 13, the end of the main body 10, and the inner surface of the closed end of the lid member 30.
A membrane filter 20 is provided at the end of the body 10. In this case, the membrane filter 20 may be subjected to water-repellent or oil-repellent treatment in accordance with the required specifications.
Wherein the membrane filter 20 is provided in a state of being fastened to the end of the body 10. That is, the membrane filter 20 is attached to the end of the body 10 by using an adhesive on the body 10. The filter may be attached by other processing methods such as ultrasonic welding, thermal welding, and laser welding.
The main body 10 and the cover member 30 may be formed of materials having different elastic modulus. That is, the body 10 is formed of an elastic polymer, and the cover member 30 may be formed of a synthetic resin. The main body 10 is made of a material having a high elastic modulus, such as an elastic polymer, and can be firmly assembled between the opening 101 and the lid member 30.
In this case, the length of the body 10 may be greater than that of the cover member 30. By making the length of the main body 10 longer, the position can be easily visually confirmed when the main body is assembled to the opening 101, and the assembling property can be improved.
On the other hand, referring to fig. 4, a schematic view of ventilation performed in the automotive ventilation cap 1 of the present invention is shown. As shown in the figure, first, the outside air flows between the diameter-reduced portion 11 of the main body 10 and the inner side surface of the cover member 30.
Then, the filtrate is filtered through the vent hole 13 of the enlarged diameter portion 12 and flows into the closed end inner surface of the lid member 30.
Finally, after moving along the inner surface of the closed end surface toward the center, the fluid flows into the hollow portion of the body 10 through the membrane filter 20, and finally flows into the member 100 through the opening 101. Of course, the internal air of the above-described component 100 is discharged in the opposite direction.
As described above, the air flows in the vertical direction, and particularly, flows along the vent hole 13, and thus, the present invention is suitable for a member requiring air permeability.
Further, by manufacturing a plurality of bodies 10 having different numbers and diameters of the vent holes 13, an appropriate body 10 can be selected and assembled according to a desired ventilation amount.
On the other hand, fig. 5 and 6 show a breathable cap 1 for an automobile according to a second embodiment of the present invention. Referring to fig. 5 and 6, the ventilation cap 1 is different from the first embodiment in that the cover member 30 is provided with the adjustment projection 31a along an arc.
In this case, the adjustment projection 31a is provided on the inner surface of the lid member 30 along an arc having the same diameter as that of the arc in which the vent hole 13 is formed. The adjusting protrusion 31a is smaller than a height of the space 30 a.
As described above, the adjustment protrusion 31a is aligned with the vent hole 13 so that the cap member 30 is slightly rotated with respect to the body 10, thereby easily adjusting the ventilation amount. In particular, if the cover member 30 is formed of a transparent or translucent material, the worker can adjust the ventilation amount more easily. That is, referring to fig. 5, since the regulating protrusion 31a and the vent hole 13 are not overlapped, the ventilation amount can be maximized. In this state, when the lid member 30 is slightly rotated with respect to the main body 10, the adjustment projection 31a and the vent hole 13 start to overlap each other, and the ventilation amount is reduced in proportion to the overlapping area, and finally, the ventilation amount can be arbitrarily adjusted.
While one embodiment of the present invention has been described above, the idea of the present invention is not limited to the embodiment disclosed in the present specification, and a person having ordinary skill in the art understanding the idea of the present invention can easily propose another embodiment by adding, changing, deleting, adding, etc. components within the scope of the same idea, and also fall within the scope of the idea of the present invention.
