1 is an exploded perspective view of a vehicle antenna according to a sealing example of the present invention, and FIGS. 2 to 4 show detailed structures of an upper case, a lower case, and a rubber pad of FIG. 1, respectively.

In the present embodiment, a shark antenna is shown as an example of a vehicle antenna, and the sak antenna is an upper case UC, an antenna circuit ATC, a lower case DC, and a rubber pad PAD, as shown in FIG. ).

1 and 2, the upper case UC is opened to be coupled to the lower case DC, the air resistance is minimized when the vehicle is performed, and the antenna circuit ATC is disposed inside the outside. In order to protect the antenna circuit (ATC) from the environment, it can be implemented in the form of a streamlined dome with an empty interior. The upper case UC may be made of, for example, a material of a plastic polymer compound such as polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (PC + ABS).

In addition, a boss BO into which the case coupling member CSCR is inserted is coupled to the upper case UC so that the case coupling member CSCR such as the lower case DC and the screw may be coupled thereto. Can be formed. The upper case UC coupled to the lower case DC by the case coupling member CSCR may be coupled in such a manner that an open lower case edge CEG applies pressure to the rubber pad PAD.

In addition, the upper case UC may further include a watertight partition rib WBR in an empty space therein. The watertight barrier rib WBR may be formed in a shape corresponding to the substrate guide SGD of the lower case DC to be described later. For example, the watertight bulkhead rib WBR is formed along an outer shape of the substrate guide SGD of the lower case DC, and when the upper case UC and the lower case DC are coupled to each other, an outer portion of the substrate guide SGD is formed. It is formed to surround the, it is possible to further prevent the inflow of moisture to the antenna circuit (ATC) disposed on the substrate guide (SGD).

On the other hand, the antenna circuit (ATC) is a portion that transmits and receives a radio signal to function as an actual antenna, it may include a substrate (SUB) and a plurality of circuit elements and antenna elements disposed on the substrate (SUB). In particular, the antenna circuit (ATC) may include a variety of circuit elements and antenna elements to transmit and receive radio signals of various communication methods other than a specific communication method. The antenna circuit ATC is fixedly coupled to a designated position of the lower case DC.

Hereinafter, the lower case DC will be described with reference to FIGS. 1 and 3. In FIG. 3, (a) is a top view of the lower case DC, and (b) is a bottom view.

The lower case DC mounts and fixes the antenna circuit ATC inside the antenna ANT. The lower case DC may be formed of a metal material such as aluminum or zinc so as to stably support the antenna circuit ATC.

The lower case DC is provided with a substrate guide SGD for designating a mounting position of the antenna circuit ATC, and the substrate guide protrusions are mounted so that the antenna circuit ATC is stably mounted and fixed to the substrate guide SGD. SGB) and substrate fastening hole SLH may be formed. The substrate fastening hole SLH may include a substrate coupling member such that the substrate SUB on which various circuit elements of the antenna circuit ATC are disposed is coupled to the lower case DC using a substrate coupling member SSCR such as a screw. Means a hole into which an SSCR) is inserted.

In addition, a case fastening hole CLH may be formed in the lower case DC to be coupled to the upper case UC using the case coupling member CSCR. The case fastening hole CLH of the lower case DC is formed corresponding to the position of the boss BO formed in the upper case UC. As shown in FIG. 1, the case coupling member CSCR is inserted into the boss BO of the upper case UC through the case fastening hole CLH of the lower case DC, thereby lowering the antenna ANT. Combine the case DC and the upper case UC.

The upper surface of the lower case (DC) is formed with a guide boss (GBO) protruding in the form to surround the case fastening hole (CLH). The guide boss GBO not only guides the case coupling member CSCR inserted into the boss BO of the upper case UC through the case fastening hole CLH, but also the boss BO of the upper case UC. The upper case UC or the boss BO of the upper case is prevented from being damaged by the case coupling member CSCR.

In addition, a fastening member may be formed in the lower case DC to fix the antenna ANT to the vehicle. In this case, the fastening member may be formed as, for example, a columnar fastener (LH) having a thread. The fastener LH of the lower case DC is inserted into the vehicle through an antenna hole prepared in advance in the vehicle, and the inserted fastener LH is fastened to the corresponding antenna nut in the vehicle to connect the antenna ANT to the vehicle. Can be fixed at

That is, the lower case DC may be coupled to the antenna circuit ATC and the upper case UC by using the substrate coupling member SSCR and the case coupling member CSCR, and may use a fastener LH as a fastening member. To allow the antenna ANT to be mounted on the vehicle.

In addition, the lower case DC has a wired line so that the antenna circuit ATC can transmit or receive a signal to the vehicle through the lower case DC and receive a power voltage and a ground voltage to the antenna circuit ATC. The cable hole CH may be further formed to pass therethrough.

When the lower case DC and the upper case UC are coupled by the coupling member CSCR, the rubber pad PAD is connected to the lower case DC and the upper case UC by the elasticity of the rubber pad PAD. In addition to preventing damage, water is prevented from flowing into the antenna along the interface between the lower case DC and the upper case UC.

When the antenna pad is fastened to the vehicle, the rubber pad PAD allows the antenna to be stably adhered to the vehicle and prevents water from flowing into the antenna or inside the vehicle along the interface between the antenna and the outside of the vehicle. In addition, the appearance of the vehicle and the antenna are matched to minimize the damage to the appearance of the vehicle due to the mounting of the antenna.

The rubber pad PAD may be integrally formed with the lower case DC so as to surround the outer case of the lower case DC. 4 illustrates a rubber pad PAD coupled to the lower case DC.

Also in FIG. 4, (a) shows the top view of the rubber pad PAD, and (b) shows the bottom view.

Referring to FIGS. 1 and 4, the rubber pad PAD may be manufactured by insert injection molding so as to be integrally formed with the lower case DC. At this time, the rubber pad PAD that is injected into the insert is fixed in a form that the injected rubber passes through the through hole TH of the lower case DC, thereby increasing the bonding force between the rubber pad PAD and the lower case DC, After the rubber pad (PAD) can be formed so as not to be separated from the lower case (DC).

Here, the rubber pad (PAD), for example, may be composed of a soft vulcanized rubber having a hardness of 50 to 70 degrees, such as EPDM (Ethylene Propylene Diene Monomer), TPE (Thermoplastic Elastomer).

The rubber pad PAD may be formed at the position corresponding to the lower end of the case edge CEG of the upper case UC at the upper side edge of the rubber pad PAD. The case coupling plane portion CLPA is formed such that the lower end of the case edge CEG of the upper case UC is in stable contact so that moisture does not penetrate therein.

In addition, the rubber pad PAD may be formed flat on the upper surface of the lower case DC. The plane here may be referred to as a partition wall plane part BLPA. The partition coupling plane portion BLPA is formed to have a predetermined height from an upper surface of the lower case DC. For example, the partition-coupling plane portion BLPA may be formed to surround the substrate guide SGD to a predetermined height.

When the upper case UC and the lower case DC are coupled to each other, the watertight partition ribs WBR formed on the upper case UC apply pressure to a corresponding position on the partition coupling plane portion BLPA of the rubber pad PAD. Will be added.

The watertight bulkhead rib WBR additionally blocks water from entering the antenna circuit ATC similarly to the case edge CEG by applying pressure to the bulkhead coupling plane BLPA of the rubber pad PAD.

At this time, the rubber pad PAD may be easily inserted into the boss BO of the upper case UC through the case coupling hole CLH of the lower case DC. It is not formed in the area.

In addition, the rubber pad PAD may have a vehicle fastening hole corresponding to a region of the fastener LH and the cable hole CH at a lower surface thereof. In other words, the rubber pad PAD is fastened to the vehicle through the fastener LH and the cable hole CH, and the vehicle is fastened so that various cables can be connected between the inside of the vehicle and the antenna circuit ATC. Holes may be formed.

In addition, a plurality of watertight ribs WR1 to WR3 may be formed on the bottom surface of the rubber pad. The plurality of watertight ribs WR1 to WR3 are formed to prevent moisture from flowing through the interface between the antenna ANT and the vehicle.

Three inflow paths of water that can flow from the antenna ANT to the antenna circuit ATC disposed therein can be considered. First, moisture may flow into the interface where the upper case UC and the lower case DC of the antenna are coupled. Secondly, moisture can flow through the interface where the antenna and vehicle are coupled. Finally, the moisture may be introduced along the space where the coupling member for coupling the upper case UC and the lower case DC is fastened.

The plurality of watertight ribs WR1 to WR3 are formed to prevent moisture from flowing through the interface between the antenna and the vehicle in the water inflow path. The watertight ribs WR1 and WR2 disposed at the outer side of the plurality of watertight ribs WR1 to WR3 may be formed in different sizes with shapes corresponding to the shape of the bottom surface of the rubber pad PAD. However, several milliseconds WR3 and WR4 formed in the lower surface of the rubber pad PAD may be formed regardless of the shape of the lower surface of the rubber pad PAD. For example, in FIG. 4, the third watertight rib WR3 is formed in a shape corresponding to the outer shape of the substrate guide SGD, and the fourth water mill rib WR4 is formed in a shape corresponding to the vehicle fastening hole.

However, the plurality of watertight ribs WR1 to WR4 may be formed in a closed loop structure on the lower surface of the rubber pad PAD to block water introduced into the inside.

In addition, the plurality of watertight ribs WR1 to WR3 are gradually narrowed at the bottom so that the antenna ANT is easily bent by the pressure applied in the vertical direction of the lower surface of the rubber pad PAD when the antenna ANT is coupled to the vehicle. Loss may be formed in the form.

In addition, the plurality of watertight ribs WR1 to WR3 must be bent outward from the bottom surface of the rubber pad PAD to prevent water from being introduced into the inside. Accordingly, the watertight ribs WR1 to WR3 may be formed to have a predetermined angle in the outer surface direction so as to be easily bent in the outer direction.

Here, each of the plurality of watertight ribs WR1 to WR3 may be formed to have different angles and lengths, and each of the plurality of watertight ribs WR1 to WR3 may be formed to have different angles and lengths depending on positions. This is because the outer surface of the vehicle on which the antenna ANT is mounted is often not flat.

On the other hand, the waterproof performance by the plurality of watertight ribs WR1 to WR3 is improved as the compression ratio indicating the change in shape of the rubber due to pressure increases. However, if the compression ratio is increased by increasing the pressure in the vertical direction on the lower surface of the rubber pad (PAD) to improve the waterproof performance, even if the water-tight ribs WR1 to WR3 are easily formed to bend outward, Due to the elasticity of the watertight ribs WR1 to WR3, a bending deformation (dent) occurs on the engaging surface of the vehicle. For this reason, there is a limit in raising waterproof performance.

In addition, when the water-tight ribs WR1 to WR3 are formed too thin, the elasticity is insufficient and the waterproof performance is lowered. That is, when the watertight ribs WR1 to WR3 are formed to bend easily even at low pressure, the waterproof performance is lowered.

However, in the rubber pad PAD according to the present embodiment, rib compression grooves PCF are formed on the outer side of at least one watertight rib among the plurality of watertight ribs WR1 to WR3. As the rib compression groove (PCF) is formed, the watertight ribs have a space that can be bent in the outward direction. In addition, the rubber pad PAD in the region where the rib compression groove PCF is formed is thinner than the other regions. Therefore, the watertight ribs having the rib compression grooves PCF formed on the outer side thereof (for example, the third watertight ribs WR3) have a lower elasticity than the case where the rib compression grooves PCF are not formed even though the compression ratio due to pressure is increased. Will have Therefore, it does not cause bending deformation in the vehicle while improving waterproof performance.

5 is a cross-sectional view illustrating a plurality of watertight ribs and rib compression grooves in the rubber pad of FIG.

FIG. 5 is an enlarged cross-sectional view of the area indicated by the circle of FIG. 4. Referring to FIG. 5, in the present example, the third watertight rib WR3 of the first to third watertight ribs WR1 to WR3 is one example. Ribbed compression groove (PCF) was formed only on the outside of the.

In the case of the first watertight rib WR1, the watertight rib formed at the outermost side of the lower surface of the rubber pad PAD does not have a space therein, and thus, the rib compression groove PCF cannot be formed. However, as the first watertight rib WR1 is disposed at the outermost side of the rubber pad PAD, the end may be formed to face the outer direction of the rubber pad PAD. When the end is formed so as to face the outward direction of the rubber pad (PAD), although the compression ratio is lowered, it does not cause bending deformation in the vehicle. That is, although the rib compression groove PCF may not be formed in the first watertight rib WR1, the first watertight rib WR1 is formed to face outwardly of the pad at a predetermined angle so as not to cause bending deformation in the vehicle.

On the other hand, the second watertight rib WR2 is formed at a position corresponding to the case edge CEG of the upper case UC on the lower surface of the rubber pad PAD. The position in close contact with the case edge CEG of the upper case UC in the rubber pad PAD corresponds to the case joining plane portion CLPA, and as shown in FIG. 5, the case joining plane in the rubber pad PAD. The thickness t1 of the portion CLPA is thinner than the thickness t2 in the other region.

Therefore, the thickness t1 of the outer side of the second watertight rib WR2 on the lower surface of the rubber pad PAD is thinner than the thickness t2 of the inner side, so that the second watertight rib WR2 is easily bent in the lower outward direction. Can be. That is, since the outer side of the second watertight rib WR2 on the lower surface of the rubber pad PAD has a structure similar to that of the rib compression groove PCF, the rib compression groove PCF does not need to be formed.

That is, in the present embodiment, the rib compression groove PCF may be selectively formed according to the structure of the rubber pad PAD instead of being formed at the outer periphery of all the watertight ribs WR1 to WR3. In particular, the rib compression grooves PCF may not be formed in the watertight ribs WR1 and WR2 formed in the region corresponding to the case coupling plane portion CLPA on the outer side of the rubber pad PAD.

FIG. 6 shows a process of mounting an antenna on a vehicle according to an embodiment of the present invention, and FIG. 7 shows changes in watertight rib shape before and after the vehicle is mounted on the antenna.

In FIG. 6, for example, it is assumed that the antenna ANT is mounted on the roof RF of the upper part of the vehicle.

Referring to FIG. 6, in the antenna ANT in which the upper case UC, the lower case DC, and the rubber pad PAD are coupled, a fastener LH formed at a lower portion of the lower case DC is inserted into the vehicle. do. In this case, a loop hole RFH into which the fastener LH may be inserted is formed in the loop RF in which the antenna ANT is disposed. In addition, the loop hole RFH may be formed in a form through which various cables connected through the fastener LH and the cable hole CH may pass.

When the fastener LH is inserted into the vehicle through the roof hole RFH, the antenna nut NUT is fastened to the fastener LH inside the vehicle. When the antenna nut NUT is coupled by a screw thread formed in the fastener LH, the antenna ANT is coupled to and fixed to the loop RF of the vehicle. At this time, the plurality of watertight ribs WR1 to WR4 are compressed. At this time, the plurality of compressed watertight ribs WR1 to WR4 block moisture flowing into the vehicle between the loop RF and the antenna ANT.

Particularly, in the present embodiment, rib compression grooves PCF are formed along the periphery of at least one of the watertight ribs WR3 and WR4 among the plurality of watertight ribs WR1 to WR4 on the lower surface of the rubber pad PAD. As shown in FIG. 2, the shape change of the watertight ribs WR3 and WR4 before and after the vehicle mounting of the antenna ANT may occur more than when the rib compression groove PCF is not formed. That is, since the rib compression groove PCF is formed, the compression ratio of the watertight ribs WR3 and WR4 can be increased, and at the same time, the bending deformation of the loop that can be caused by the elasticity of the watertight rib can be minimized.

As a result, it is possible to prevent the bending deformation from occurring in the vehicle while improving the waterproof performance of the antenna ANT. In addition, the watertight ribs WR1 to WR4 are formed to bend in the outward direction from the lower surface of the rubber pad PAD, so that the resistance of the watertight ribs to the inside of the fastening process in which the antenna ANT is mounted on the vehicle. This can reduce the likelihood of errors being directed. Therefore, the convenience of the fastening process can be improved.

8 shows a structure of a rib compression groove according to another embodiment of the present invention.

In FIG. 8, rib compression grooves PCF1 and PCF2 are formed not only on the outer side of the watertight rib WR3 but also on the inner side thereof. The rib compression groove PCF1 formed on the outer side of the watertight rib WR3 provides an empty space in which the watertight rib WR3 can change shape as described above, thereby increasing the compression ratio of the watertight rib WR3. On the other hand, the rib compression groove PCF2 formed on the inner side of the watertight rib WR3 provides the same effect as the length of the watertight rib WR3 along with the rib compression groove PCF1 formed on the outer side, thereby providing a watertight rib WR3. ) Can be modified more. That is, the compression ratio of the watertight rib WR3 can be further increased.

Therefore, the waterproof performance of the antenna ANT by the watertight rib WR3 can be further improved.

However, referring to FIG. 7, in the case of the fourth watertight rib WR4, the height of the inner portion of the watertight rib WR4 on the rubber pad PAD is different from the height of the outer portion. This is due to the structure of the vehicle fastening hole formed in the rubber pad, and has a structure similar to that already formed even if a separate rib compression groove PCF2 is not formed. As shown in Fig. 7, in the rubber pad PAD, when the length of the watertight rib on the inner side is longer than the length on the outer side, the rib compression groove PCF2 may not be generated.

As a result, the waterproof structure of the vehicle antenna according to the embodiment of the present invention forms a compression groove outside the waterproof rib on the lower surface of the rubber pad, so that the waterproof rib of the vehicle antenna fastened to the vehicle naturally faces the outer direction and contacts the vehicle. By making the waterproof ribs closely adhere to the vehicle and increase the extrusion rate, the waterproof performance can be improved, and since the waterproof rib does not apply excessive pressure to the exterior of the vehicle, it is possible to prevent the bending deformation from occurring in the exterior of the vehicle.

In addition, by reducing the possibility that the waterproof ribs are directed inward in the fastening process between the vehicle and the vehicle antenna, it is possible to obtain a stable waterproof performance by reducing the possibility of the problem that the waterproof performance is degraded by the fastening process, and convenience in the process Can greatly improve.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.

Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
